Update

Based on Manipulating the browser history, passing the empty string as second parameter of pushState method (aka title) should be safe against future changes to the method, so it's better to use pushState like this:

history.pushState(null, '', '/en/step2');    

You can read more about that in mentioned article

Original Answer

Use history.pushState like this:

history.pushState(null, null, '/en/step2');

• More info (MDN article): Manipulating the browser history
• Can I use
• Maybe you should take a look @ Does Internet Explorer support pushState and replaceState?

Update 2 to answer Idan Dagan's comment:

Why not using history.replaceState()?

From MDN

history.replaceState() operates exactly like history.pushState() except that replaceState() modifies the current history entry instead of creating a new one

That means if you use replaceState, yes the url will be changed but user can not use Browser's Back button to back to prev. state(s) anymore (because replaceState doesn't add new entry to history) and it's not recommended and provide bad UX.

Update 3 to add window.onpopstate

So, as this answer got your attention, here is additional info about manipulating the browser history, after using pushState, you can detect the back/forward button navigation by using window.onpopstate like this:

window.onpopstate = function(e) {
    // ... 
};

As the first argument of pushState is an object, if you passed an object instead of null, you can access that object in onpopstate which is very handy, here is how:

window.onpopstate = function(e) {
    if(e.state) {
        console.log(e.state);
    }
};

Update 4 to add Reading the current state:

When your page loads, it might have a non-null state object, you can read the state of the current history entry without waiting for a popstate event using the history.state property like this:

console.log(history.state);

Bonus: Use following to check history.pushState support:

if (history.pushState) {
  // \o/
}

I solved that problem on Mac OSX (10.10) by using -K option for ssh-add:

ssh-add -K ~/.ssh/your_private_key

For macOS 10.12 and later you need to additionally edit your ssh config as described here: https://github.com/jirsbek/SSH-keys-in-macOS-Sierra-keychain

yourElement.setAttribute("style", "background-color:red; font-size:2em;");

Or you could write the element as pure HTML and use .innerHTML = [raw html code]... that's very ugly though.

In answer to your first question, first you use var myElement = createElement(...);, then you do document.body.appendChild(myElement);.

If you want to disable the clickable, you can also add inline this in html

style="cursor: not-allowed;"

I was able to get this to work by adding it to the body tag. Was nicer for me because I don't have anything on the html element.

body {
    overflow-y: scroll;
}

IEquatable<T> can be a much easier way to do this with modern frameworks.

You get a nice simple bool Equals(T other) function and there's no messing around with casting or creating a separate class.

public class Person : IEquatable<Person>
{
    public Person(string name, string hometown)
    {
        this.Name = name;
        this.Hometown = hometown;
    }

    public string Name { get; set; }
    public string Hometown { get; set; }

    // can't get much simpler than this!
    public bool Equals(Person other)
    {
        return this.Name == other.Name && this.Hometown == other.Hometown;
    }

    public override int GetHashCode()
    {
        return Name.GetHashCode();  // see other links for hashcode guidance 
    }
}

Note you DO have to implement GetHashCode if using this in a dictionary or with something like Distinct.

PS. I don't think any custom Equals methods work with entity framework directly on the database side (I think you know this because you do AsEnumerable) but this is a much simpler method to do a simple Equals for the general case.

If things don't seem to be working (such as duplicate key errors when doing ToDictionary) put a breakpoint inside Equals to make sure it's being hit and make sure you have GetHashCode defined (with override keyword).

Much simpler...try day(eomonth(@Date))

The point is that the first line of your codes is not what you expected.

You should use:

val map = scala.collection.mutable.Map[A,B]()

You then have multiple equivalent alternatives to add items:

scala> val map = scala.collection.mutable.Map[String,String]()
map: scala.collection.mutable.Map[String,String] = Map()


scala> map("k1") = "v1"

scala> map
res1: scala.collection.mutable.Map[String,String] = Map((k1,v1))


scala> map += "k2" -> "v2"
res2: map.type = Map((k1,v1), (k2,v2))


scala> map.put("k3", "v3")
res3: Option[String] = None

scala> map
res4: scala.collection.mutable.Map[String,String] = Map((k3,v3), (k1,v1), (k2,v2))

And starting Scala 2.13:

scala> map.addOne("k4" -> "v4")
res5: map.type = HashMap(k1 -> v1, k2 -> v2, k3 -> v3, k4 -> v4)

If you want to initialize the list with N elements of some fixed value:

public List<T> InitList<T>(int count, T initValue)
{
  return Enumerable.Repeat(initValue, count).ToList();
}

Just ssh'ing to the host is not enough, on Windows at least. That adds the host key to ssh/known_hosts but the error still persists.

You need to close the git bash window and open a new one. Then the registry cache is cleared and the push/pull then works.

While I agree that this should not be a comment, but a docstring as most (all?) answers suggest, I want to add numpydoc (a docstring style guide).

If you do it like this, you can (1) automatically generate documentation and (2) people recognize this and have an easier time to read your code.

To store the array values in cookie, first you need to convert them to string, so here is some options.

Storing cookies as JSON

Storing code

setcookie('your_cookie_name', json_encode($info), time()+3600);

Reading code

$data = json_decode($_COOKIE['your_cookie_name'], true);

JSON can be good choose also if you need read cookie in front end with JavaScript.

Actually you can use any encrypt_array_to_string/decrypt_array_from_string methods group that will convert array to string and convert string back to same array. For example you can also use explode/implode for array of integers.

Warning: Do not use serialize/unserialize

From PHP.net

Do not pass untrusted user input to unserialize(). - Anything that coming by HTTP including cookies is untrusted!

As an alternative solution, you can do it also without converting array to string.

setcookie('my_array[0]', 'value1' , time()+3600);
setcookie('my_array[1]', 'value2' , time()+3600);
setcookie('my_array[2]', 'value3' , time()+3600);

And after if you will print $_COOKIE variable, you will see the following

echo '<pre>';
print_r( $_COOKIE );
die();

Array
(   
    [my_array] => Array
        (
            [0] => value1
            [1] => value2
            [2] => value3
        )

)

This is documented PHP feature.

From PHP.net

Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system.

Elasticsearch accepts GET requests with a body. It even seems that this is the preferred way: Elasticsearch guide

Some client libraries (like the Ruby driver) can log the cry command to stdout in development mode and it is using this syntax extensively.

Small edit to @seengee answer: In order to work, you need curly braces around the variable, otherwise you'll get an error.

header("Content-type: {$imginfo['mime']}");

The above answers regarding @JsonProperty and CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES are 100% accurate, although some people (like me) might be trying to do this inside a Spring MVC application with code-based configuration. Here's sample code (that I have inside Beans.java) to achieve the desired effect:

@Bean
public ObjectMapper jacksonObjectMapper() {
    return new ObjectMapper().setPropertyNamingStrategy(
            PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);
}

.set_title('') can be used to add title to Seaborn Plot

import seaborn as sb
sb.boxplot().set_title('Title')

Function makeRed and makeBlack use queue and dequeue to execute each other. The effect is that, the '#wow' element blinks continuously.

<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
    <script type="text/javascript">
      $(document).ready(function(){
          $('#wow').click(function(){
            $(this).delay(200).queue(makeRed);
            });
          });

      function makeRed(){
        $('#wow').css('color', 'red');
        $('#wow').delay(200).queue(makeBlack);
        $('#wow').dequeue();
      }

      function makeBlack(){
        $('#wow').css('color', 'black');
        $('#wow').delay(200).queue(makeRed);
        $('#wow').dequeue();
      }
    </script>
  </head>
  <body>
    <div id="wow"><p>wow</p></div>
  </body>
</html>

You could actually use xlsread to accomplish this. After first placing your sample data above in a file 'input_file.csv', here is an example for how you can get the numeric values, text values, and the raw data in the file from the three outputs from xlsread:

>> [numData,textData,rawData] = xlsread('input_file.csv')

numData =     % An array of the numeric values from the file

   51.9358    4.1833
   51.9354    4.1841
   51.9352    4.1846
   51.9343    4.1864
   51.9343    4.1864
   51.9341    4.1869


textData =    % A cell array of strings for the text values from the file

    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'


rawData =     % All the data from the file (numeric and text) in a cell array

    'ABC'    [51.9358]    [4.1833]
    'ABC'    [51.9354]    [4.1841]
    'ABC'    [51.9352]    [4.1846]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9341]    [4.1869]

You can then perform whatever processing you need to on the numeric data, then resave a subset of the rows of data to a new file using xlswrite. Here's an example:

index = sqrt(sum(numData.^2,2)) >= 50;  % Find the rows where the point is
                                        %   at a distance of 50 or greater
                                        %   from the origin
xlswrite('output_file.csv',rawData(index,:));  % Write those rows to a new file

You can try a list comp

>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

Another way is by using filter

>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

Try This

SELECT f.*
FROM first_table f LEFT JOIN second_table s ON f.key=s.key
WHERE s.key is NULL

This is easier since Java 9. A Duration still isn’t formattable, but methods for getting the hours, minutes and seconds are added, which makes the task somewhat more straightforward:

    LocalDateTime start = LocalDateTime.of(2019, Month.JANUARY, 17, 15, 24, 12);
    LocalDateTime end = LocalDateTime.of(2019, Month.JANUARY, 18, 15, 43, 33);
    Duration diff = Duration.between(start, end);
    String hms = String.format("%d:%02d:%02d", 
                                diff.toHours(), 
                                diff.toMinutesPart(), 
                                diff.toSecondsPart());
    System.out.println(hms);

The output from this snippet is:

24:19:21

I have been seeing the exact same error today, but it was not a config or direct JavaScript issue.

An external .net project had been updated but the changes not picked up properly in the compilation of the web site. My presumption is that ASP.NET ajax was not able to construct the client representations of the .NET objects properly and so was failing to load correctly.

To resolve, I rebuilt the external project(s), and rebuilt my solution that was experiencing issues. The problem went away.

First, what you are looking for is a column or bar diagram, not really a histogram. A histogram is made from a frequency distribution of a continuous variable that is separated into bins. Here you have a column against separate labels.

To make a bar diagram with matplotlib, use the matplotlib.pyplot.bar() method. Have a look at this page of the matplotlib documentation that explains very well with examples and source code how to do it.

If it is possible though, I would just suggest that for a simple task like this if you could avoid writing code that would be better. If you have any spreadsheet program this should be a piece of cake because that's exactly what they are for, and you won't have to 'reinvent the wheel'. The following is the plot of your data in Excel:

I just copied your data from the question, used the text import wizard to put it in two columns, then I inserted a column diagram.

For writing if statement inline, the code inside of it should only be one statement:

if ( a < b ) // code to be executed without curly braces;

Maybe something like this

ps -eo pid,pcpu,comm

And if you like to parse and maybe only look at some processes.

#!/bin/sh
ps -eo pid,pcpu,comm | awk '{if ($2 > 4) print }' >> ~/ps_eo_test.txt

In a git bash session, you can add a script to ~/.profile or ~/.bashrc (with ~ being usually set to %USERPROFILE%), in order for said session to launch automatically the ssh-agent. If the file doesn't exist, just create it.

This is what GitHub describes in "Working with SSH key passphrases".

The "Auto-launching ssh-agent on Git for Windows" section of that article has a robust script that checks if the agent is running or not. Below is just a snippet, see the GitHub article for the full solution.

# This is just a snippet. See the article above.
if ! agent_is_running; then
    agent_start
    ssh-add
elif ! agent_has_keys; then
    ssh-add
fi

Other Resources:

"Getting ssh-agent to work with git run from windows command shell" has a similar script, but I'd refer to the GitHub article above primarily, which is more robust and up to date.

I had a similar problem. I was working on a project where I did not control the web.xml configuration file, so I could not use the changes suggested about altering the version. Of course the project was not using JSF so this was especially annoying for me.

I found that there is a really simple fix. Go to Preferences > Maven > Java EE Itegration and uncheck the "JSF Configurator" box.

I did this in a fresh workspace before importing the project again, but it may work equally as well on an existing project ... not sure.

Another work-around is to construct a string with a temporary substitute character. Then you can use REPLACE to change each temp character to the double quote. I use tilde as the temporary substitute character.

Here is an example from a project I have been working on. This is a little utility routine to repair a very complicated formula if/when the cell gets stepped on accidentally. It is a difficult formula to enter into a cell, but this little utility fixes it instantly.

Sub RepairFormula()
Dim FormulaString As String

FormulaString = "=MID(CELL(~filename~,$A$1),FIND(~[~,CELL(~filename~,$A$1))+1,FIND(~]~, CELL(~filename~,$A$1))-FIND(~[~,CELL(~filename~,$A$1))-1)"
FormulaString = Replace(FormulaString, Chr(126), Chr(34)) 'this replaces every instance of the tilde with a double quote.
Range("WorkbookFileName").Formula = FormulaString

This is really just a simple programming trick, but it makes entering the formula in your VBA code pretty easy.

There are two ways to create custom ToggleButton

1) By defining custom background 2) By creating custom button

Check http://www.zoftino.com/android-toggle-button for custom styles

Toggle button with custom background

Define drawable as xml resource like below and set it as background of toggle button. In the below example, drawable toggle_color is a color selector, you need to define this also.

<?xml version="1.0" encoding="utf-8"?>

                    <shape android:shape="rectangle"
                        android:tint="?attr/android:colorButtonNormal">

                        <solid android:color="@android:color/white" />
                        <padding android:left="8dp"

                            android:bottom="6dp" />
                    </shape>
                </item>
            </ripple>

                <size android:width="8dp" />
                <solid android:color="@color/toggle_color" />
            </shape>
        </item>
    </layer-list>
</inset>

Toggle button with custom button

Create your own images for two state of toggle button (make sure images exist for all sizes of screens) and place them in drawable folder, create selector and set it as button.

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

Typically, there is no difference - the BETWEEN keyword is not supported on all RDBMS platforms, but if it is, the two queries should be identical.

Since they're identical, there's really no distinction in terms of speed or anything else - use the one that seems more natural to you.

Adding this to your iframe might resolve the issue:

frameborder="0"  seamless="seamless"

The name scrambling is used to ensure that subclasses don't accidentally override the private methods and attributes of their superclasses. It's not designed to prevent deliberate access from outside.

For example:

>>> class Foo(object):
...     def __init__(self):
...         self.__baz = 42
...     def foo(self):
...         print self.__baz
...     
>>> class Bar(Foo):
...     def __init__(self):
...         super(Bar, self).__init__()
...         self.__baz = 21
...     def bar(self):
...         print self.__baz
...
>>> x = Bar()
>>> x.foo()
42
>>> x.bar()
21
>>> print x.__dict__
{'_Bar__baz': 21, '_Foo__baz': 42}

Of course, it breaks down if two different classes have the same name.

I wanted to make a version of this that uses $.getJSON() from a separate JSON file.

    var selectData, $states;

    function updateSelects() {
        var cities = $.map(selectData[this.value], function (city) {
            return $("<option />").text(city);
        });
        $("#city_names").empty().append(cities);
    }

    $.getJSON("updateSelect.json", function (data) {
        var state;
        selectData = data;
        $states = $("#us_states").on("change", updateSelects);
        for (state in selectData) {
            $("<option />").text(state).appendTo($states);
        }
        $states.change();
    });
});

I developed a noSQL database for storing DOM trees in Web Browsers where references to all DOM elements on page are stored in a short index. Thus function "getElementById()" is not needed to get/modify an element. When elements in DOM tree are instantiated on page the database assigns surrogate primary keys to each element. It is a free tool http://js2dx.com

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

Yes, you can.

I was able to set the height of my SELECT to exactly what I wanted in IE8 and 9. The trick is to set the box-sizing property to content-box. Doing so will set the content area of the SELECT to the height, but keep in mind that margin, border and padding values will not be calculated in the width/height of the SELECT, so adjust those values accordingly.

select {
    display: block;
    padding: 6px 4px;
    -moz-box-sizing: content-box;
    -webkit-box-sizing:content-box;
    box-sizing:content-box;
    height: 15px;
}

Here is a working jsFiddle. Would you mind confirming and marking the appropriate answer?

This worked for me well.

angular.forEach(element.find('div'), function(node)
{
  if(node.id == 'someid'){
    //do something
  }
  if(node.className == 'someclass'){
    //do something
  }
});

I tried this out for transmitting continuous data (float values converted to string) from my PC (MATLAB) to my phone. But, still my App misreads the delimiter '\n' and still data gets garbled. So, I took the character 'N' as the delimiter rather than '\n' (it could be any character that doesn't occur as part of your data) and I've achieved better transmission speed - I gave just 0.1 seconds delay between transmitting successive samples - with more than 99% data integrity at the receiver i.e. out of 2000 samples (float values) that I transmitted, only 10 were not decoded properly in my application.

My answer in short is: Choose a delimiter other than '\r' or '\n' as these create more problems for real-time data transmission when compared to other characters like the one I've used. If we work more, may be we can increase the transmission rate even more. I hope my answer helps someone!

Are you posting from a different source (so different port, or hostname)? If so, this very very recent topic I just answered might be helpful.

• Odd jQuery problem - Ajax request to a C program not quite working

The problem was the XHR Cross Domain Policy, and a useful tip on how to get around it by using a technique called JSONP. The big downside is that JSONP does not support POST requests.

I know in the original post there is no mention of JavaScript, however JSON is usually used for JavaScript so that's why I jumped to that conclusion

Short answer:

We can't live without onStart because that is the state when the activity becomes "visible" to the user, but the user cant "interact" with it yet may be cause it's overlapped with some other small dialog. This ability to interact with the user is the one that differentiates onStart and onResume. Think of it as a person behind a glass door. You can see the person but you can't interact (talk/listen/shake hands) with him. OnResume is like the door opener after which you can begin the interaction.

Additionally onRestart() is the least understood one. We can ask the question as to why not directly go to onStart() or onResume() after onStop() instead of onRestart(). It becomes easier to understand if we note that onRestart() is partially equivalent to onCreate() if the creation part is omitted. Basically both states lead to onStart() (i.e the Activity becomes visible). So both the states have to "prepare" the stuff to be displayed. OnCreate has the additional responsibility to "create" the stuff to be displayed

So their code structures might fit to something like:

onCreate()
{
     createNecessaryObjects();

     prepareObjectsForDisplay();
}


onRestart()
{
     prepareObjectsForDisplay();

}

The entire confusion is caused since Google chose non-intuitive names instead of something as follows:

onCreateAndPrepareToDisplay()   [instead of onCreate() ]
onPrepareToDisplay()            [instead of onRestart() ]
onVisible()                     [instead of onStart() ]
onBeginInteraction()            [instead of onResume() ]
onPauseInteraction()            [instead of onPause() ]
onInvisible()                   [instead of onStop]
onDestroy()                     [no change] 

The Activity Diagram might be interpreted as:

Obviously, there are a lot of solutions to this. Here is another one though:

wc -l somefile | tr -d "[:alpha:][:blank:][:punct:]"

This only outputs the number of lines, but the trailing newline character (\n) is present, if you don't want that either, replace [:blank:] with [:space:].

In the link you provided, thats not a loop in sql...

thats a loop in programming language

they are first getting list of all distinct districts, and then for each district executing query again.

My HTML page had these starting tags:

This was on a page that using the slick jquery slideshow.

I removed the tags and replaced with:

Specify a size for the item and warehouse like in the [dbo].[testing1] FUNCTION

@trackingItems1 TABLE (
item       nvarchar(25)  NULL, -- 25 OR equal size of your item column
warehouse   nvarchar(25) NULL, -- same as above
price int   NULL

) 

Since in MSSQL only saying only nvarchar is equal to nvarchar(1) hence the values of the column from the stock table are truncated

Remove the coma at the end of your SELECT statement (VALUE,), and also remove the one at the end of your FROM statement (rrf b,)

If you want to stay close to .NET check out Enterprise Library Logging Application Block. Look here. Or for a quickstart tutorial check this. I have used the Validation application Block from the Enterprise Library and it really suits my needs and is very easy to "inherit" (install it and refrence it!) in your project.

Simpler than ever, forget about ViewTypes. Is not recommended to use multiple viewtypes inside one adapter, it will mess the code and break the single responsibility principle since now the adapter needs to handle logic to know which view to inflate, now imagine working in large teams where each team has to work in one of those viewtypes features, it will be a mess to touch the same adapter by all the teams that work in the different viewtypes, this is solved using ConcatAdapter where you isolate the adapters, code them one by one and then just merge them inside one view.

From recyclerview:1.2.0-alpha04 you now can use ConcatAdapter

If you need a view with different viewTypes , you can just write the Adapters for each section and just use ConcatAdapter to merge all of them inside one recyclerview

ConcatAdapter

This image shows 3 different viewtypes that one recyclerview has, header, content and footer.

You only create one adapter for each section, and then just use ConcatAdapter to merge them inside one recyclerview

val firstAdapter: FirstAdapter = …
val secondAdapter: SecondAdapter = …
val thirdAdapter: ThirdAdapter = …
val concatAdapter = ConcatAdapter(firstAdapter, secondAdapter, 
     thirdAdapter)
recyclerView.adapter = concatAdapter

Thats all you need to know, if you want to handle loading state, for example remove the last adapter after some loading happened, you can use LoadState

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

Local variables do not get default values. Their initial values are undefined without assigning values by some means. Before you can use local variables they must be initialized.

There is a big difference when you declare a variable at class level (as a member, i.e., as a field) and at the method level.

If you declare a field at the class level they get default values according to their type. If you declare a variable at the method level or as a block (means any code inside {}) do not get any values and remain undefined until somehow they get some starting values, i.e., some values assigned to them.

To add a little to @Bakuriu's answer:

If you already know where the warning is likely to occur then it's often cleaner to use the numpy.errstate context manager, rather than numpy.seterr which treats all subsequent warnings of the same type the same regardless of where they occur within your code:

import numpy as np

a = np.r_[1.]
with np.errstate(divide='raise'):
    try:
        a / 0   # this gets caught and handled as an exception
    except FloatingPointError:
        print('oh no!')
a / 0           # this prints a RuntimeWarning as usual

Edit:

In my original example I had a = np.r_[0], but apparently there was a change in numpy's behaviour such that division-by-zero is handled differently in cases where the numerator is all-zeros. For example, in numpy 1.16.4:

all_zeros = np.array([0., 0.])
not_all_zeros = np.array([1., 0.])

with np.errstate(divide='raise'):
    not_all_zeros / 0.  # Raises FloatingPointError

with np.errstate(divide='raise'):
    all_zeros / 0.  # No exception raised

with np.errstate(invalid='raise'):
    all_zeros / 0.  # Raises FloatingPointError

The corresponding warning messages are also different: 1. / 0. is logged as RuntimeWarning: divide by zero encountered in true_divide, whereas 0. / 0. is logged as RuntimeWarning: invalid value encountered in true_divide. I'm not sure why exactly this change was made, but I suspect it has to do with the fact that the result of 0. / 0. is not representable as a number (numpy returns a NaN in this case) whereas 1. / 0. and -1. / 0. return +Inf and -Inf respectively, per the IEE 754 standard.

If you want to catch both types of error you can always pass np.errstate(divide='raise', invalid='raise'), or all='raise' if you want to raise an exception on any kind of floating point error.

If you are open to using Perl, that would be my suggestion. Although there are probably some sed and/or AWK experts that probably know how to do this much easier. If you have a more complex mapping with more than just dbName for your replacements you could extend this pretty easily, but you might just as well put it into a standard Perl script at that point.

perl -p -e 's/\$\{dbName\}/testdb/s' yourfile | mysql

A short Perl script to do something slightly more complicated (handle multiple keys):

#!/usr/bin/env perl
my %replace = ( 'dbName' => 'testdb', 'somethingElse' => 'fooBar' );
undef $/;
my $buf = <STDIN>;
$buf =~ s/\$\{$_\}/$replace{$_}/g for keys %replace;
print $buf;

If you name the above script as replace-script, it could then be used as follows:

replace-script < yourfile | mysql

It's October 2017, and Google makes Android Support Library with the new things call Lifecycle component. It provides some new idea for this 'Can not perform this action after onSaveInstanceState' problem.

In short:

• Use lifecycle component to determine if it's correct time for popping up your fragment.

Longer version with explain:

• why this problem come out?

  It's because you are trying to use FragmentManager from your activity(which is going to hold your fragment I suppose?) to commit a transaction for you fragment. Usually this would look like you are trying to do some transaction for an up coming fragment, meanwhile the host activity already call savedInstanceState method(user may happen to touch the home button so the activity calls onStop(), in my case it's the reason)

  Usually this problem shouldn't happen -- we always try to load fragment into activity at the very beginning, like the onCreate() method is a perfect place for this. But sometimes this do happen, especially when you can't decide what fragment you will load to that activity, or you are trying to load fragment from an AsyncTask block(or anything will take a little time). The time, before the fragment transaction really happens, but after the activity's onCreate() method, user can do anything. If user press the home button, which triggers the activity's onSavedInstanceState() method, there would be a can not perform this action crash.

  If anyone want to see deeper in this issue, I suggest them to take a look at this blog post. It looks deep inside the source code layer and explain a lot about it. Also, it gives the reason that you shouldn't use the commitAllowingStateLoss() method to workaround this crash(trust me it offers nothing good for your code)

• How to fix this?

  • Should I use commitAllowingStateLoss() method to load fragment? Nope you shouldn't;

  • Should I override onSaveInstanceState method, ignore super method inside it? Nope you shouldn't;

  • Should I use the magical isFinishing inside activity, to check if the host activity is at the right moment for fragment transaction? Yeah this looks like the right way to do.

• Take a look at what Lifecycle component can do.

  Basically, Google makes some implementation inside the AppCompatActivity class(and several other base class you should use in your project), which makes it a easier to determine current lifecycle state. Take a look back to our problem: why would this problem happen? It's because we do something at the wrong timing. So we try not to do it, and this problem will be gone.

  I code a little for my own project, here is what I do using LifeCycle. I code in Kotlin.

val hostActivity: AppCompatActivity? = null // the activity to host fragments. It's value should be properly initialized.

fun dispatchFragment(frag: Fragment) {
    hostActivity?.let {
       if(it.lifecyclecurrentState.isAtLeast(Lifecycle.State.RESUMED)){
           showFragment(frag)
       }
    }
}

private fun showFragment(frag: Fragment) {
    hostActivity?.let {
        Transaction.begin(it, R.id.frag_container)
                .show(frag)
                .commit()
    }

As I show above. I will check the lifecycle state of the host activity. With Lifecycle component within support library, this could be more specific. The code lifecyclecurrentState.isAtLeast(Lifecycle.State.RESUMED) means, if current state is at least onResume, not later than it? Which makes sure my method won't be execute during some other life state(like onStop).

• Is it all done?

  Of course not. The code I have shown tells some new way to prevent application from crashing. But if it do go to the state of onStop, that line of code wont do things and thus show nothing on your screen. When users come back to the application, they will see an empty screen, that's the empty host activity showing no fragments at all. It's bad experience(yeah a little bit better than a crash).

  So here I wish there could be something nicer: app won't crash if it comes to life state later than onResume, the transaction method is life state aware; besides, the activity will try continue to finished that fragment transaction action, after the user come back to our app.

  I add something more to this method:

class FragmentDispatcher(_host: FragmentActivity) : LifecycleObserver {
    private val hostActivity: FragmentActivity? = _host
    private val lifeCycle: Lifecycle? = _host.lifecycle
    private val profilePendingList = mutableListOf<BaseFragment>()

    @OnLifecycleEvent(Lifecycle.Event.ON_RESUME)
    fun resume() {
        if (profilePendingList.isNotEmpty()) {
            showFragment(profilePendingList.last())
        }
    }

    fun dispatcherFragment(frag: BaseFragment) {
        if (lifeCycle?.currentState?.isAtLeast(Lifecycle.State.RESUMED) == true) {
            showFragment(frag)
        } else {
            profilePendingList.clear()
            profilePendingList.add(frag)
        }
    }

    private fun showFragment(frag: BaseFragment) {
        hostActivity?.let {
            Transaction.begin(it, R.id.frag_container)
                    .show(frag)
                    .commit()
        }
    }
}

I maintain a list inside this dispatcher class, to store those fragment don't have chance to finish the transaction action. And when user come back from home screen and found there is still fragment waiting to be launched, it will go to the resume() method under the @OnLifecycleEvent(Lifecycle.Event.ON_RESUME) annotation. Now I think it should be working like I expected.

In order to get new refresh_token each time on authentication the type of OAuth 2.0 credentials created in the dashboard should be "Other". Also as mentioned above the access_type='offline' option should be used when generating the authURL.

When using credentials with type "Web application" no combination of prompt/approval_prompt variables will work - you will still get the refresh_token only on the first request.

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

response, err := http.PostForm(APIURL, url.Values{

    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

I have similar problem. Spring 4 and Tomcat 8. I solve the problem with Spring configuration

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
    <property name="initialSize" value="10" />
    <property name="maxActive" value="25" />
    <property name="maxIdle" value="20" />
    <property name="minIdle" value="10" />
     ...
    <property name="testOnBorrow" value="true" />
    <property name="validationQuery" value="SELECT 1" />
 </bean>

I have tested. It works well! This two line does everything in order to reconnect to database:

<property name="testOnBorrow" value="true" />
<property name="validationQuery" value="SELECT 1" />

You could do something like this

String[] myStrings = { "One", "Two", "Three" };

or in expression

functionCall(new String[] { "One", "Two", "Three" });

or

String myStrings[];
myStrings = new String[] { "One", "Two", "Three" };

There are several mechanisms to avoid a link to reach its destination. The one from the question is not much intuitive.

A cleaner option is to use href="#no" where #no is a non-defined anchor in the document.

You can use a more semantic name such as #disable, or #action to increase readability.

Benefits of the approach:

• Avoids the "moving to the top" effect of the empty href="#"
• Avoids the use of javascript

Drawbacks:

• You must be sure the anchor name is not used in the document.
• The URL changes to include the (non-existing) anchor as fragment and a new browser history entry is created. This means that clicking the "back" button after clicking the link won't behave as expected.

Since the <a> element is not acting as a link, the best option in these cases is not using an <a> element but a <div> and provide the desired link-like style.

If this problem is still flummoxing you and you are developing using Eclipse, have a look at this Eclipse bug: Resources files from "src/main/resources" are not correctly included in classpath

Solution seems to be look at properties of project, Java build path, source folders. Delete the /src/main/resources dir and add it again. This causes Eclipse to be reminded it needs to copy these files to the classpath.

This bug affected me when using the "Neon" release of Eclipse. (And was very frustrating until I realized the simple fix just described)

Here is how I solved my problem:

Directive

app.directive("directive_name", function(){
    return {
        restrict: 'E',
        transclude: true,
        template: function(elem, attr){
           return '<div><h2>{{'+attr.scope+'}}</h2></div>';
        },
        replace: true
    };
})

Controller

$scope.building = function(data){
    var chart = angular.element(document.createElement('directive_name'));
    chart.attr('scope', data);
    $compile(chart)($scope);
    angular.element(document.getElementById('wrapper')).append(chart);
  }

I now can use different scopes through the same directive and append them dynamically.

Yes. Recent versions of IE (IE8 or above) let you adjust that. Here's how:

• Fire up Internet Explorer.
• Click the 'Tools' menu, then click 'Developer Tools'. Alternatively, just press F12.

That should open the Developer Tools window. That window has two menu items that are of interest:

• Browser Mode. This setting determines the value of the user-agent header sent for every request.
• Document Mode. This setting determines how the rendering engine renders the page.

I'm using DotNet Core MVC and after fighting for a few hours with nuget packages, Startup.cs, attributes, and this place, I simply added this to the MVC action:

Response.Headers.Add("Access-Control-Allow-Origin", "*");

I realise this is pretty clunky, but it's all I needed, and nothing else wanted to add those headers. I hope this helps someone else!

Just to close this

foreach (KeyValuePair<DateTime, string> kvp in dictionary)
{
    //textBox3.Text += ("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
    Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}

Changes to this

foreach (KeyValuePair<DateTime, string> kvp in dictionary)
{
    //textBox3.Text += ("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
    textBox3.Text += string.Format("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}

The 'file' protocol is not a network protocol. Therefore file://192.168.1.57/~User/2ndFile.html simply does not make much sense.

Question is how you load the first file. Is that really done using a web server? Does not really sound like. If it is, then why not use the same protocol, most likely http? You cannot expect to simply switch the protocol and use two different protocols the same way...

I suspect the first file is really loaded using the apache server at all, but simply by opening the file? href="2ndFile.html" simply works because it uses a "relative url". This makes the browser use the same protocol and path as where he got the first (current) file from.

Yes there is a problem with Click event handler (klik) - First argument must be an object type and second must be EventArgs.

public void klik(object sender, EventArgs e) {
  //
}

If you want to paint on a form or control then use CreateGraphics method.

public void klik(object sender, EventArgs e) {
    Bitmap c = this.DrawMandel();
    Graphics gr = CreateGraphics();  // Graphics gr=(sender as Button).CreateGraphics();
    gr.DrawImage(b, 150, 200);
}

As well as using Package manager console to get nuget to update the project with Install-Package Microsoft.AspNet.WebApi.WebHost for missing GlobalConfiguration,

I needed Install-Package Microsoft.AspNet.WebApi.SelfHost for missing using System.Web.Http;

Sometimes just setting canvas's tabindex to '1' (or '0') works. But sometimes - it doesn't, for some strange reason.

In my case (ReactJS app, dynamic canvas el creation and mount) I need to call canvasEl.focus() to fix it. Maybe this is somehow related to React (my old app based on KnockoutJS works without '..focus()' )

Try:

git config core.fileMode false

From git-config(1):

core.fileMode
    Tells Git if the executable bit of files in the working tree
    is to be honored.

    Some filesystems lose the executable bit when a file that is
    marked as executable is checked out, or checks out a
    non-executable file with executable bit on. git-clone(1)
    or git-init(1) probe the filesystem to see if it handles the 
    executable bit correctly and this variable is automatically
    set as necessary.

    A repository, however, may be on a filesystem that handles
    the filemode correctly, and this variable is set to true when
    created, but later may be made accessible from another
    environment that loses the filemode (e.g. exporting ext4
    via CIFS mount, visiting a Cygwin created repository with Git
    for Windows or Eclipse). In such a case it may be necessary
    to set this variable to false. See git-update-index(1).

    The default is true (when core.filemode is not specified
    in the config file).

The -c flag can be used to set this option for one-off commands:

git -c core.fileMode=false diff

And the --global flag will make it be the default behavior for the logged in user.

git config --global core.fileMode false

Changes of the global setting won't be applied to existing repositories. Additionally, git clone and git init explicitly set core.fileMode to true in the repo config as discussed in Git global core.fileMode false overridden locally on clone

Warning

core.fileMode is not the best practice and should be used carefully. This setting only covers the executable bit of mode and never the read/write bits. In many cases you think you need this setting because you did something like chmod -R 777, making all your files executable. But in most projects most files don't need and should not be executable for security reasons.

The proper way to solve this kind of situation is to handle folder and file permission separately, with something like:

find . -type d -exec chmod a+rwx {} \; # Make folders traversable and read/write
find . -type f -exec chmod a+rw {} \;  # Make files read/write

If you do that, you'll never need to use core.fileMode, except in very rare environment.

Your user don't have the right permissions to read the file, since you used open() without specifying a mode.

Since you're using Windows, you should read a little more about File and Folder Permissions.

Also, if you want to play with your file permissions, you should right-click it, choose Properties and select Security tab.

Or if you want to be a little more hardcore, you can run your script as admin.

Because neither == nor the equals() method of the array compare the contents; both only evaluate object identity (== always does, and equals() is not overwritten, so the version from Object is being used).

For comparing the contents, use Arrays.equals().

Assuming:

1. You have 2's-complement representations in mind; and,
2. By (unsigned long) you mean unsigned 32-bit integer,

then you just need to add 2**32 (or 1 << 32) to the negative value.

For example, apply this to -1:

>>> -1
-1
>>> _ + 2**32
4294967295L
>>> bin(_)
'0b11111111111111111111111111111111'

Assumption #1 means you want -1 to be viewed as a solid string of 1 bits, and assumption #2 means you want 32 of them.

Nobody but you can say what your hidden assumptions are, though. If, for example, you have 1's-complement representations in mind, then you need to apply the ~ prefix operator instead. Python integers work hard to give the illusion of using an infinitely wide 2's complement representation (like regular 2's complement, but with an infinite number of "sign bits").

And to duplicate what the platform C compiler does, you can use the ctypes module:

>>> import ctypes
>>> ctypes.c_ulong(-1)  # stuff Python's -1 into a C unsigned long
c_ulong(4294967295L)
>>> _.value
4294967295L

C's unsigned long happens to be 4 bytes on the box that ran this sample.

If you need one single regex, try:

(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)

A short explanation:

(?=.*[a-z])        // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z])        // use positive look ahead to see if at least one upper case letter exists
(?=.*\d)           // use positive look ahead to see if at least one digit exists
(?=.*\W])        // use positive look ahead to see if at least one non-word character exists

And I agree with SilentGhost, \W might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?] (feel free to add more of course!)

MD5 is considered broken, not because you can get back the original content from the hash, but because with work, you can craft two messages that hash to the same hash.

You cannot un-hash an MD5 hash.

An example usage:

>>> s = 'Hello world'
>>> t = buffer(s, 6, 5)
>>> t
<read-only buffer for 0x10064a4b0, size 5, offset 6 at 0x100634ab0>
>>> print t

The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string.

This isn't very useful for short strings like this, but it can be necessary when using large amounts of data. This example uses a mutable bytearray:

>>> s = bytearray(1000000)   # a million zeroed bytes
>>> t = buffer(s, 1)         # slice cuts off the first byte
>>> s[1] = 5                 # set the second element in s
>>> t[0]                     # which is now also the first element in t!
'\x05'

This can be very helpful if you want to have more than one view on the data and don't want to (or can't) hold multiple copies in memory.

Note that buffer has been replaced by the better named memoryview in Python 3, though you can use either in Python 2.7.

Note also that you can't implement a buffer interface for your own objects without delving into the C API, i.e. you can't do it in pure Python.

I found it is better to use the command Serial.readString() to replace the Serial.read() to obtain the continuous I/O for Arduino.

Used below code to display custom list in AlertDialog

AlertDialog.Builder builderSingle = new AlertDialog.Builder(DialogActivity.this);
builderSingle.setIcon(R.drawable.ic_launcher);
builderSingle.setTitle("Select One Name:-");

final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(DialogActivity.this, android.R.layout.select_dialog_singlechoice);
arrayAdapter.add("Hardik");
arrayAdapter.add("Archit");
arrayAdapter.add("Jignesh");
arrayAdapter.add("Umang");
arrayAdapter.add("Gatti");

builderSingle.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

builderSingle.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String strName = arrayAdapter.getItem(which);
                AlertDialog.Builder builderInner = new AlertDialog.Builder(DialogActivity.this);
                builderInner.setMessage(strName);
                builderInner.setTitle("Your Selected Item is");
                builderInner.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog,int which) {
                                dialog.dismiss();
                            }
                        });
                builderInner.show();
            }
        });
builderSingle.show();

HTML

<div id='a'>
  <div>
    <a class='click'>abc</a>
  </div>
</div>

You could use the XPATH as :

//div[@id='a']//a[@class='click']

output

<a class="click">abc</a>

That said your Python code should be as :

driver.find_element_by_xpath("//div[@id='a']//a[@class='click']")

This command:

git ls-tree --full-tree -r --name-only HEAD

lists all of the already committed files being tracked by your git repo.

update 
  table1 t1
set
  (
    t1.column1, 
    t1.column2
      ) = (
    select
      t2.column1, 
      t2.column2
    from
      table2  t2
    where
      t2.column1 = t1.column1
     )
    where exists (
      select 
        null
      from 
        table2 t2
      where 
        t2.column1 = t1.column1
      );

Or this (if t2.column1 <=> t1.column1 are many to one and anyone of them is good):

update 
  table1 t1
set
  (
    t1.column1, 
    t1.column2
      ) = (
    select
      t2.column1, 
      t2.column2
    from
      table2  t2
    where
      t2.column1 = t1.column1
    and
      rownum = 1    
     )
    where exists (
      select 
        null
      from 
        table2 t2
      where 
        t2.column1 = t1.column1
      ); 

Is there maybe a way to grab the rendered page from the internet explorer rendering engine and send it to a PDF-Printer tool automatically?

This is how ActivePDF works, which is good means that you know what you'll get, and it actually has reasonable styling support.

It is also one of the few packages I found (when looking a few years back) that actually supports the various page-break CSS commands.

Unfortunately, the ActivePDF software is very frustrating - since it has to launch the IE browser in the background for conversions it can be quite slow, and it is not particularly stable either.

There is a new version currently in Beta which is supposed to be much better, but I've not actually had a chance to try it out, so don't know how much of an improvement it is.

Made this new helper function in TypeScript, maybe someone will appreciate it. If you remove type declaration from script parameter it will just be plain JS.

const evalPageScripts = () => {
  const scripts = document.querySelectorAll('script');

  scripts.forEach((script: HTMLScriptElement) => {
    const newScript = document.createElement('script');
    newScript.type = 'text/javascript';
    newScript.src = script.src;

    if (script.parentNode) {
      script.parentNode.removeChild(script);
    }

    return document.body.appendChild(newScript);
  })
};

export default evalPageScripts;

As mentioned above, res.locals is a good (recommended) way to do this. See here for a quick tutorial on how to do this in Express.

[Note: edited to modernize ggplot syntax]

Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot. One advantage is that ggplot works with data.frames directly.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.

library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  xlab("My x label") +
  ylab("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area("Nitrogen") + 
  scale_x_continuous("My x label") +
  scale_y_continuous("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  labs(size= "Nitrogen",
       x = "My x label",
       y = "My y label",
       title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

which gives an identical figure to the one above.

Consider if instead it was:

class RectangularRoom(object):
    def __init__(self, width, height):
        pass

    def cleanTileAtPosition(self, pos):
        pass

    def isTileCleaned(self, m, n):
        pass

and you subclass and forget to tell it how to isTileCleaned() or, perhaps more likely, typo it as isTileCLeaned(). Then in your code, you'll get a None when you call it.

• Will you get the overridden function you wanted? Definitely not.
• Is None valid output? Who knows.
• Is that intended behavior? Almost certainly not.
• Will you get an error? It depends.

raise NotImplmentedError forces you to implement it, as it will throw an exception when you try to run it until you do so. This removes a lot of silent errors. It's similar to why a bare except is almost never a good idea: because people make mistakes and this makes sure they aren't swept under the rug.

Note: Using an abstract base class, as other answers have mentioned, is better still, as then the errors are frontloaded and the program won't run until you implement them (with NotImplementedError, it will only throw an exception if actually called).

myOptions = {
        center: myLatlng,
        minZoom: 6,
        maxZoom: 9,
        styles: customStyles,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };

Here's another way:

var myspan = document.getElementById('myspan');

if (myspan.innerText) {
    myspan.innerText = "newtext";
}
else
if (myspan.textContent) {
        myspan.textContent = "newtext";   
}

The innerText property will be detected by Safari, Google Chrome and MSIE. For Firefox, the standard way of doing things was to use textContent but since version 45 it too has an innerText property, as someone kindly apprised me recently. This solution tests to see if a browser supports either of these properties and if so, assigns the "newtext".

simpler:

re.findall(r'/(?!ignoreme)(\w+)',  "/hello /ignoreme and /ignoreme2 /ignoreme2M.")

you will get:

['hello']

The best way to get a browser's default styling on something is to not style the element at all in the first place.

Usually a back-reference is either $1 or \1 (backslash one) for the first capture group (the first match of a pattern in parentheses), and indeed Sublime supports both syntaxes. So try:

my name used to be \1

or

my name used to be $1

Also note that your original capture pattern:

my name is (\w)+

is incorrect and will only capture the final letter of the name rather than the whole name. You should use the following pattern to capture all of the letters of the name:

my name is (\w+)

If you are familiar with git you'll be happy to use histedit that works like git rebase -i.

I had the same problem, and neither umount /path -f, neither umount.nfs /path -f, neither fuser -km /path, works

finally I found a simple solution >.<

sudo /etc/init.d/nfs-common restart, then lets do the simple umount ;-)

Do one of the two jQuery serializers inside your form submit to get all inputs having a submitted value.

var criteria = $(this).find('input,select').filter(function () {
    return ((!!this.value) && (!!this.name));
}).serializeArray();

var formData = JSON.stringify(criteria);

serializeArray() will produce an array of names and values

0: {name: "OwnLast", value: "Bird"}
1: {name: "OwnFirst", value: "Bob"}
2: {name: "OutBldg[]", value: "PDG"}
3: {name: "OutBldg[]", value: "PDA"}

var criteria = $(this).find('input,select').filter(function () {
    return ((!!this.value) && (!!this.name));
}).serialize();

serialize() creates a text string in standard URL-encoded notation

"OwnLast=Bird&OwnFirst=Bob&OutBldg%5B%5D=PDG&OutBldg%5B%5D=PDA"

The error message says

"The path to the driver executable must be set by the webdriver.ie.driver system property;"

You are setting the path for the Chrome Driver with "webdriver.chrome.driver" property. You are not setting the file location when for InternetExplorerDriver, to do that you must set "webdriver.ie.driver" property.

You can set these properties in your shell, via maven, or your IDE with the -DpropertyName=Value

-Dwebdriver.ie.driver="C:/.../IEDriverServer.exe" 

You need to use quotes because of spaces or slashes in your path on windows machines, or alternatively reverse the slashes other wise they are the string string escape prefix.

You could also use

System.setProperty("webdriver.ie.driver","C:/.../IEDriverServer.exe"); 

inside your code.

Yo can try this:

SELECT CURDATE();

If you check the following:

SELECT NOW(); SELECT DATE(NOW()); SELECT DATE_FORMAT(NOW(),'%Y-%m-%d');

You can see that it takes a long time.

This is what I did.
First, just override the jumbotron class, and do the following:

.jumbotron{
    background: url("bg.jpg") no-repeat center center; 
    -webkit-background-size: 100% 100%;
    -moz-background-size: 100% 100%;
    -o-background-size: 100% 100%;
    background-size: 100% 100%;
}

So, now you have a jumbotron with responsive background in place. However, as Irvin Zhan already answered, the height of the background still not showing correctly.

One thing you can do is fill your div with some spaces such as this:

<div class="jumbotron">
    <div class="container">
        About
        <br><br><br> <!--keep filling br until the height is to your liking-->
    </div>
</div>

Or, more elegantly, you can set the height of the container. You might want to add another class so that you don't override Bootstrap container class.

<div class="jumbotron">
    <div class="container push-spaces">
        About
    </div>
</div>

.push-spaces
{
    height: 100px;
}

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called.

This is why you get a compiler warning when you write

 MyClass myObject = new MyClass();
 myObject.myStaticMethod();
 // should be written as
 MyClass.myStaticMethod()
 // because it is not dispatched on myObject
 myObject = new MySubClass();
 myObject.myStaticMethod(); 
 // still calls the static method in MyClass, NOT in MySubClass

Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

 Integer.parseInt("10");
 Integer.parseInt("AA", 16);

Probably the shortest would be str(s or '')

Because None is False, and "x or y" returns y if x is false. See Boolean Operators for a detailed explanation. It's short, but not very explicit.

POCO is simply an object that does not take a dependency on an external framework. It is PLAIN.

Whether a POCO has behaviour or not it's immaterial.

A DTO may be POCO as may a domain object (which would typically be rich in behaviour).

Typically DTOs are more likely to take dependencies on external frameworks (eg. attributes) for serialisation purposes as typically they exit at the boundary of a system.

In typical Onion style architectures (often used within a broadly DDD approach) the domain layer is placed at the centre and so its objects should not, at this point, have dependencies outside of that layer.

First of all we should get clear that Hadoop was created as a faster alternative to RDBMS. To process large amount of data at a very fast rate which earlier took a lot of time in RDBMS.

Now one should know the two terms :

1. Structured Data : This is the data that we used in traditional RDBMS and is divided into well defined structures.

2. Unstructured Data : This is important to understand, about 80% of the world data is unstructured or semi structured. These are the data which are on its raw form and cannot be processed using RDMS. Example : facebook, twitter data. (http://www.dummies.com/how-to/content/unstructured-data-in-a-big-data-environment.html).

So, large amount of data was being generated in the last few years and the data was mostly unstructured, that gave birth to HADOOP. It was mainly used for very large amount of data that takes unfeasible amount of time using RDBMS. It had many drawbacks, that it could not be used for comparatively small data in real time but they have managed to remove its drawbacks in the newer version.

Before going further I would like to tell that a new Big Data tool is created when they see a fault on the previous tools. So, whichever tool you will see that is created has been done to overcome the problem of the previous tools.

Hadoop can be simply said as two things : Mapreduce and HDFS. Mapreduce is where the processing takes place and HDFS is the DataBase where data is stored. This structure followed WORM principal i.e. write once read multiple times. So, once we have stored data in HDFS, we cannot make changes. This led to the creation of HBASE, a NOSQL product where we can make changes in the data also after writing it once.

But with time we saw that Hadoop had many faults and for that we created different environment over the Hadoop structure. PIG and HIVE are two popular examples.

HIVE was created for people with SQL background. The queries written is similar to SQL named as HIVEQL. HIVE was developed to process completely structured data. It is not used for ustructured data.

PIG on the other hand has its own query language i.e. PIG LATIN. It can be used for both structured as well as unstructured data.

Moving to the difference as when to use HIVE and when to use PIG, I don't think anyone other than the architect of PIG could say. Follow the link : https://developer.yahoo.com/blogs/hadoop/comparing-pig-latin-sql-constructing-data-processing-pipelines-444.html

According to your query Select * from [User] U where U.DateCreated = '2014-02-07'

SQL Server is comparing exact date and time i.e (comparing 2014-02-07 12:30:47.220 with 2014-02-07 00:00:00.000 for equality). that's why result of comparison is false

Therefore, While comparing dates you need to consider time also. You can use
Select * from [User] U where U.DateCreated BETWEEN '2014-02-07' AND '2014-02-08'.

public class Application {

    private static List<HttpMessageConverter<?>> getMessageConverters() {

        return converters;
    }   

    public static void main(String[] args) {
        RestTemplate restTemplate = new RestTemplate();

        restTemplate.setMessageConverters(getMessageConverters());

First you should ensure that your command object is not null. Then you should set the CommandText property of the command to your sql query. Finally you should store the return value in an object variable and check if it is null before using it:

command = new OracleCommand(connection)
command.CommandText = sql
object userNameObj = command.ExecuteScalar()
if (userNameObj != null)
  string getUserName = userNameObj.ToString()
 ...

I'm not sure about the VB syntax but you get the idea.

Short and simple:

def ave(x,y):
  return (x + y) / 2.0

map(ave, a[:-1], a[1:])

And here's how it looks:

>>> a = range(10)
>>> map(ave, a[:-1], a[1:])
[0.5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.5, 8.5]

Due to some stupidity in how Python handles a map over two lists, you do have to truncate the list, a[:-1]. It works more as you'd expect if you use itertools.imap:

>>> import itertools
>>> itertools.imap(ave, a, a[1:])
<itertools.imap object at 0x1005c3990>
>>> list(_)
[0.5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.5, 8.5]

I like using the static initializer "technique" when I have a concrete realization of an abstract class that has defined an initializing constructor but no default constructor but I want my subclass to have a default constructor.

For example:

public abstract class Shape {

    public static final String COLOR_KEY = "color_key";
    public static final String OPAQUE_KEY = "opaque_key";

    private final String color;
    private final Boolean opaque;

    /**
     * Initializing constructor - note no default constructor.
     *
     * @param properties a collection of Shape properties
     */
    public Shape(Map<String, Object> properties) {
        color = ((String) properties.getOrDefault(COLOR_KEY, "black"));
        opaque = (Boolean) properties.getOrDefault(OPAQUE_KEY, false);
    }

    /**
     * Color property accessor method.
     *
     * @return the color of this Shape
     */
    public String getColor() {
        return color;
    }

    /**
     * Opaque property accessor method.
     *
     * @return true if this Shape is opaque, false otherwise
     */
    public Boolean isOpaque() {
        return opaque;
    }
}

and my concrete realization of this class -- but it wants/needs a default constructor:

public class SquareShapeImpl extends Shape {

    private static final Map<String, Object> DEFAULT_PROPS = new HashMap<>();

    static {
        DEFAULT_PROPS.put(Shape.COLOR_KEY, "yellow");
        DEFAULT_PROPS.put(Shape.OPAQUE_KEY, false);
    }

    /**
     * Default constructor -- intializes this square to be a translucent yellow
     */
    public SquareShapeImpl() {
        // the static initializer was useful here because the call to 
        // this(...) must be the first statement in this constructor
        // i.e., we can't be mucking around and creating a map here
        this(DEFAULT_PROPS);
    }

    /**
     * Initializing constructor -- create a Square with the given
     * collection of properties.
     *
     * @param props a collection of properties for this SquareShapeImpl
     */
    public SquareShapeImpl(Map<String, Object> props) {
        super(props);
    }
}

then to use this default constructor, we simply do:

public class StaticInitDemo {

    public static void main(String[] args) {

        // create a translucent, yellow square...
        Shape defaultSquare = new SquareShapeImpl();

        // etc...
    }
}

I wrote a drawable lib to custom round corner position, it looks like this:

You can get this lib at here:

This can be done by two ways according to your Android OS.

1. You can use android:largeHeap="true" in application tag of Android manifest to request a larger heap size, but this will not work on any pre Honeycomb devices.
2. On pre 2.3 devices, you can use the VMRuntime class, but this will not work on Gingerbread and above See below how to do it.

VMRuntime.getRuntime().setMinimumHeapSize(BIGGER_SIZE);

Before Setting HeapSize make sure that you have entered the appropriate size which will not affect other application or OS functionality. Before settings just check how much size your app takes & then set the size just to fulfill your job. Dont use so much of memory otherwise other apps might affect.

Reference: http://dwij.co.in/increase-heap-size-of-android-application

Here's another fix that works for me:

(event.target as HTMLInputElement).value

That should get rid of the error by letting TS know that event.target is an HTMLInputElement, which inherently has a value. Before specifying, TS likely only knew that event alone was an HTMLInputElement, thus according to TS the keyed-in target was some randomly mapped value that could be anything.

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

With EF 7:

[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
Column(TypeName = "datetime2")]
DateTime? Dateadded { get; set; }

migration script:

AlterColumn("myschema.mytable", "Dateadded", c => c.DateTime(nullable: false, precision: 7, storeType: "datetime2", defaultValueSql: "getutcdate()"));

result:

ALTER TABLE [MySchema].[MyTable] ADD  CONSTRAINT [DF_MySchema.MyTable_Dateadded]  DEFAULT (getutcdate()) FOR [Dateadded]

After exploring some of the helpful strategies provided here, I found that I only needed to add iOS specific CSS (I put it at the bottom of my main css sheet.) Seems like hiding the overflow-x was the answer for me. I assume that stating the width at 100% helps in the event that my content goes wide. It should be noted that I was only having this issue in iOS. If it is also in Firefox, just the html and body block should probably be used as the @media is specifically targeting mobile devices.

@media
only screen and (-webkit-min-device-pixel-ratio: 1.5),
only screen and (-o-min-device-pixel-ratio: 3/2),
only screen and (min--moz-device-pixel-ratio: 1.5),
only screen and (min-device-pixel-ratio: 1.5){

  html,
  body{
    width:100%;
    overflow-x:hidden;
  }

}

Please hip me if this seems incorrect to anyone :)

Here you can check to show the model state error one by one

 public HttpResponseMessage CertificateUpload(employeeModel emp)
    {
        if (!ModelState.IsValid)
        {
            string errordetails = "";
            var errors = new List<string>();
            foreach (var state in ModelState)
            {
                foreach (var error in state.Value.Errors)
                {
                    string p = error.ErrorMessage;
                    errordetails = errordetails + error.ErrorMessage;

                }
            }
            Dictionary<string, object> dict = new Dictionary<string, object>();



            dict.Add("error", errordetails);
            return Request.CreateResponse(HttpStatusCode.BadRequest, dict);


        }
        else
        {
      //do something
        }
        }

}

From a blog I found:

"This [git-credential-cache] doesn’t work for Windows systems as git-credential-cache communicates through a Unix socket."

Git for Windows

Since msysgit has been superseded by Git for Windows, using Git for Windows is now the easiest option. Some versions of the Git for Windows installer (e.g. 2.7.4) have a checkbox during the install to enable the Git Credential Manager. Here is a screenshot:

Still using msysgit? For msysgit versions 1.8.1 and above

The wincred helper was added in msysgit 1.8.1. Use it as follows:

git config --global credential.helper wincred

For msysgit versions older than 1.8.1

First, download git-credential-winstore and install it in your git bin directory.

Next, make sure that the directory containing git.cmd is in your Path environment variable. The default directory for this is C:\Program Files (x86)\Git\cmd on a 64-bit system or C:\Program Files\Git\cmd on a 32-bit system. An easy way to test this is to launch a command prompt and type git. If you don't get a list of git commands, then it's not set up correctly.

Finally, launch a command prompt and type:

git config --global credential.helper winstore

Or you can edit your .gitconfig file manually:

[credential]
    helper = winstore

Once you've done this, you can manage your git credentials through Windows Credential Manager which you can pull up via the Windows Control Panel.

The best way to do it, is to define a function, and pass it a parameter of the ID's name that you want to grab from the DOM, then every time you want to grab an ID and store it inside an array, then you can call the function

<p id="testing">Demo test!</p>

function grabbingId(element){
    var storeId = document.getElementById(element);

    return storeId;
}


grabbingId("testing").syle.color = "red";

If you need to do this in, say, a command line one-liner, it's also possible. I was able to do this for deployment on Google Colab:

1. Create a Personal Access Token: https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token
2. Run: pip install git+https://<PERSONAL ACCESS TOKEN>@github.com/<USERNAME>/<REPOSITORY>.git

Its very simple. I had implemented using -webkit-appearance: slider-vertical, It worked in chorme, Firefox, Edge

<input type="range">

input[type=range]{
    writing-mode: bt-lr; /* IE */
    -webkit-appearance: slider-vertical; /* WebKit */
    width: 50px;
    height: 200px;
    padding: 0 24px;
    outline: none;
    background:transparent;
}

Assign the response to a value and test the attributes of it. These should tell you something useful.

response = requests.post(url,params=data,headers=headers)
response.status_code
response.text

• status_code should just reconfirm the code you were given before, of course

To make a dropdown list you need two properties:

1. a property to which you will bind to (usually a scalar property of type integer or string)
2. a list of items containing two properties (one for the values and one for the text)

In your case you only have a list of string which cannot be exploited to create a usable drop down list.

While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:

@model List<string>
@Html.DropDownList(
    "Foo", 
    new SelectList(
        Model.Select(x => new { Value = x, Text = x }),
        "Value",
        "Text"
    )
)

where Foo will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:

<select name="Foo" id="Foo">
    <option value="item 1">item 1</option>
    <option value="item 2">item 2</option>
    <option value="item 3">item 3</option>
    ...
</select>

This being said a far better view model for a drop down list is the following:

public class MyListModel
{
    public string SelectedItemId { get; set; }
    public IEnumerable<SelectListItem> Items { get; set; }
}

and then:

@model MyListModel
@Html.DropDownListFor(
    x => x.SelectedItemId,
    new SelectList(Model.Items, "Value", "Text")
)

and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId property of this view model to the corresponding Value of some element in the Items collection.

You should use urllib2, like this:

import urllib2
for url in ["http://entrian.com/", "http://entrian.com/does-not-exist/"]:
    try:
        connection = urllib2.urlopen(url)
        print connection.getcode()
        connection.close()
    except urllib2.HTTPError, e:
        print e.getcode()

# Prints:
# 200 [from the try block]
# 404 [from the except block]

This answer is intended for developers.

Clearing the cache means that new shares of this webpage will show the new content which is provided in the OG tags. But only if the URL that you are working on has less than 50 interactions (likes + shares). It will also not affect old links to this webpage which have already been posted on Facebook. Only when sharing the URL on Facebook again will the way that Facebook shows the link be updated.

catandmouse's answer is correct but you can also make Facebook clear the OG (OpenGraph) cache by sending a post request to graph.facebook.com (works for both http and https as of the writing of this answer). You do not need an access token.

A post request to graph.facebook.com may look as follows:

POST / HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Host: graph.facebook.com
Content-Length: 63
Accept-Encoding: gzip
User-Agent: Mojolicious (Perl)

id=<url_encoded_url>&scrape=true

In Perl, you can use the following code where the library Mojo::UserAgent is used to send and receive HTTP requests:

sub _clear_og_cache_on_facebook {
    my $fburl     = "http://graph.facebook.com";
    my $ua        = Mojo::UserAgent->new;
    my $clearurl  = <the url you want Facebook to forget>;
    my $post_body = {id => $clearurl, scrape => 'true'};
    my $res       = $ua->post($fburl => form => $post_body)->res;
    my $code      = $res->code;
    unless ($code eq '200') {
        Log->warn("Clearing cached OG data for $clearurl failed with code $code.");
        }
    }
}

Sending this post request through the terminal can be done with the following command:

curl -F id="<URL>" -F scrape=true graph.facebook.com

Just add the cloaking CSS to the head of the page or to one of your CSS files:

[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak, .ng-hide {
    display: none !important;
}

Then you can use the ngCloak directive according to normal Angular practice, and it will work even before Angular itself is loaded.

This is exactly what Angular does: the code at the end of angular.js adds the above CSS rules to the head of the page.

Perl one-liner:

perl -pe'chomp, s/$/,/ unless eof' file

or, if you want to be more cryptic:

perl '-peeof||chomp&&s/$/,/' file

You can do this by using below code

<HorizontalScrollView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">
                    <ScrollView
                        android:layout_width="wrap_content"
                        android:layout_height="match_parent">
                        <LinearLayout
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content">
                            
                        </LinearLayout>
                    </ScrollView>
    </HorizontalScrollView>

If you'd like to link to the root directory you can use

/, or /index.html

If you'd like to link to a file in the same directory, simply put the file name

<a href="/employees.html">Employees Click Here</a>

To move back a folder, you can use

../

To link to the index page in the employees directory from the root directory, you'd do this

<a href="../employees/index.html">Employees Directory Index Page</a>

You can do this using CliWrap in one line:

var stdout = new Cli("cmd")
         .Execute("copy /b Image1.jpg + Archive.rar Image2.jpg")
         .StandardOutput;

Annotate your Entity class with the code below.

In Java:

@PrimaryKey(autoGenerate = true)
private int id;

In Kotlin:

@PrimaryKey(autoGenerate = true)
var id: Int

Room will then auto-generate and auto-increment the id field.

You can use a Deferred objects for ASYNC loading.

function load_img_async(source) {
    return $.Deferred (function (task) {
        var image = new Image();
        image.onload = function () {task.resolve(image);}
        image.onerror = function () {task.reject();}
        image.src=source;
    }).promise();
}

$.when(load_img_async(IMAGE_URL)).done(function (image) {
    $(#id).empty().append(image);
});

Please pay attention: image.onload must be before image.src to prevent problems with cache.

Use imageWithData: method, which gets translated to Swift as UIImage(data:)

let image : UIImage = UIImage(data: imageData)

You must set Preserving Object References:

var jsonSerializerSettings = new JsonSerializerSettings
{
    PreserveReferencesHandling = PreserveReferencesHandling.Objects
};

Then call your query var q = (from a in db.Events where a.Active select a).ToList(); like

string jsonStr = Newtonsoft.Json.JsonConvert.SerializeObject(q, jsonSerializerSettings);

See: https://www.newtonsoft.com/json/help/html/PreserveObjectReferences.htm

On Windows 10 and Android Studio you can go in Android Studio to "File"->"Settings" in Settings then to "Appearance & Behavior" -> "System Settings" -> "Android SDK". In the Tab "SDK Tools" active:

• "Android SDK Build-Tools .."
• "Android Emulator"
• "Android SDK Plattform-Tools"
• "Android SDK Tools"

If all installed then you can start the Emulator in Android Studio with "Tools" -> "Android" -> "AVD Manager". If the Emulator run you can try "react-native run-android"

Probably not the most efficient code, but here it goes:

$dateElements = explode('-', $dateValue);
$year = $dateElements[0];

echo $year;    //2012

switch ($dateElements[1]) {

   case '01'    :  $mo = "January";
                   break;

   case '02'    :  $mo = "February";
                   break;

   case '03'    :  $mo = "March";
                   break;

     .
     .
     .

   case '12'    :  $mo = "December";
                   break;


}

echo $mo;      //January

Judging from your example, shouldn't it be {% url myproject.login.views.login_view %} and end of story? (replace myproject with your actual project name)

Using PHP close/open tags is not very good solution because of 2 reasons: you can't print PHP variables in plain HTML and it make your code very hard to read (the next code block starts with an end bracket }, but the reader has no idea what was before).

Better is to use heredoc syntax. It is the same concept as in other languages (like bash).

 <?php
 if ($condition) {
   echo <<< END_OF_TEXT
     <b>lots of html</b> <i>$variable</i>
     lots of text...
 many lines possible, with any indentation, until the closing delimiter...
 END_OF_TEXT;
 }
 ?>

END_OF_TEXT is your delimiter (it can be basically any text like EOF, EOT). Everything between is considered string by PHP as if it were in double quotes, so you can print variables, but you don't have to escape any quotes, so it very convenient for printing html attributes.

Note that the closing delimiter must begin on the start of the line and semicolon must be placed right after it with no other chars (END_OF_TEXT;).

Heredoc with behaviour of string in single quotes (') is called nowdoc. No parsing is done inside of nowdoc. You use it in the same way as heredoc, just you put the opening delimiter in single quotes - echo <<< 'END_OF_TEXT'.

When MS-DOS and Windows 3.1 operated in 16-bit mode, an Intel 8086 word was 16 bits, a Microsoft WORD was 16 bits, a Microsoft DWORD was 32 bits, and a typical compiler's unsigned int was 16 bits.

When Windows NT operated in 32-bit mode, an Intel 80386 word was 32 bits, a Microsoft WORD was 16 bits, a Microsoft DWORD was 32 bits, and a typical compiler's unsigned int was 32 bits. The names WORD and DWORD were no longer self-descriptive but they preserved the functionality of Microsoft programs.

When Windows operates in 64-bit mode, an Intel word is 64 bits, a Microsoft WORD is 16 bits, a Microsoft DWORD is 32 bits, and a typical compiler's unsigned int is 32 bits. The names WORD and DWORD are no longer self-descriptive, AND an unsigned int no longer conforms to the principle of least surprises, but they preserve the functionality of lots of programs.

I don't think WORD or DWORD will ever change.

But in my opinion one important thing.

The "char(number)" it's lenght of variable.

If we've got table with "Names" like for example [Test1..Test200] and we declare char(5) in SELECT like:

DECLARE @variable char(5)
SET @variable = 'Test1%'
SELECT * FROM table WHERE Name like @variable

the result will be only - "Test1"! (char(5) - 5 chars in lenght; Test11 is 6 )

The rest of potential interested data like [Test11..Test200] will not be returned in the result.

It's ok if we want to limit the SELECT by this way. But if it's not intentional way of doing it could return incorrect results from planned ( Like "all Names begining with Test1..." ).

In my opinion if we don't know the precise lenght of a SELECTed value, a better solution could be something like this one:

DECLARE @variable varchar(max)
SET @variable = 'Test1%'
SELECT * FROM <table> WHERE variable1 like @variable

This returns (Test1 but also Test11..Test19 and Test100..Test199).

You can use Cursor.Current.

// Set cursor as hourglass
Cursor.Current = Cursors.WaitCursor;

// Execute your time-intensive hashing code here...

// Set cursor as default arrow
Cursor.Current = Cursors.Default;

However, if the hashing operation is really lengthy (MSDN defines this as more than 2-7 seconds), you should probably use a visual feedback indicator other than the cursor to notify the user of the progress. For a more in-depth set of guidelines, see this article.

Edit:
As @Am pointed out, you may need to call Application.DoEvents(); after Cursor.Current = Cursors.WaitCursor; to ensure that the hourglass is actually displayed.

I stumbled across this (very old) question. Interestingly the most obvious and elegant solution (imho) is missing: Array.prototype.reduce(...). All major browsers support this feature since about 2011 (IE) or even earlier (all others):

var arr = ['a','b','c','d','d','e','a','b','c','f','g','h','h','h','e','a'];_x000D_
var map = arr.reduce(function(prev, cur) {_x000D_
  prev[cur] = (prev[cur] || 0) + 1;_x000D_
  return prev;_x000D_
}, {});_x000D_
_x000D_
// map is an associative array mapping the elements to their frequency:_x000D_
document.write(JSON.stringify(map));_x000D_
// prints {"a": 3, "b": 2, "c": 2, "d": 2, "e": 2, "f": 1, "g": 1, "h": 3}

C++11 brought us lambdas, which can be incredibly useful in this situation:

#define MACRO(X,Y)                              \
    [&](x_, y_) {                               \
        cout << "1st arg is:" << x_ << endl;    \
        cout << "2nd arg is:" << y_ << endl;    \
        cout << "Sum is:" << (x_ + y_) << endl; \
    }((X), (Y))

You keep the generative power of macros, but have a comfy scope from which you can return whatever you want (including void). Additionally, the issue of evaluating macro parameters multiple times is avoided.

Here's the pattern I have used for creating plugins with additional methods. You would use it like:

$('selector').myplugin( { key: 'value' } );

or, to invoke a method directly,

$('selector').myplugin( 'mymethod1', 'argument' );

Example:

;(function($) {

    $.fn.extend({
        myplugin: function(options,arg) {
            if (options && typeof(options) == 'object') {
                options = $.extend( {}, $.myplugin.defaults, options );
            }

            // this creates a plugin for each element in
            // the selector or runs the function once per
            // selector.  To have it do so for just the
            // first element (once), return false after
            // creating the plugin to stop the each iteration 
            this.each(function() {
                new $.myplugin(this, options, arg );
            });
            return;
        }
    });

    $.myplugin = function( elem, options, arg ) {

        if (options && typeof(options) == 'string') {
           if (options == 'mymethod1') {
               myplugin_method1( arg );
           }
           else if (options == 'mymethod2') {
               myplugin_method2( arg );
           }
           return;

Thanks to cryo for improved version that I based my tested code below:

#Instead of adding silence at start and end of recording (values=0) I add the original audio . This makes audio sound more natural as volume is >0. See trim()
#I also fixed issue with the previous code - accumulated silence counter needs to be cleared once recording is resumed.

you can write the function in a separate file (say common-functions.php) and include it wherever needed.

function getEmployeeFullName($employeeId) {
// Write code to return full name based on $employeeId
}

You can include common-functions.php in another file as below.

include('common-functions.php');
echo 'Name of first employee is ' . getEmployeeFullName(1);

You can include any number of files to another file. But including comes with a little performance cost. Therefore include only the files which are really required.

You can try this UITextfield subclass which you can set a condition for the text to dynamically change the UIReturnKey:
https://github.com/codeinteractiveapps/OBReturnKeyTextField

For portability, you really should do something like this:

public static final String NEW_LINE = System.getProperty("line.separator")
.
.
.
word.contains(NEW_LINE);

unless you're absolutely certain that "\n" is what you want.

To download a file please use the following code ... Store the File name with location in $file variable. It supports all mime type

$file = "location of file to download"

header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);

To know about Mime types please refer to this link: http://php.net/manual/en/function.mime-content-type.php

You might also consider removing the need for duplicated parameter names in your Sql by changing your Sql to

table.Variable2 LIKE '%' || :VarB || '%'

and then getting your client to provide '%' for any value of VarB instead of null. In some ways I think this is more natural.

You could also change the Sql to

table.Variable2 LIKE '%' || IfNull(:VarB, '%') || '%'

You could use Timestamp.valueOf(String). The documentation states that it understands timestamps in the format yyyy-mm-dd hh:mm:ss[.f...], so you might need to change the field separators in your incoming string.

Then again, if you're going to do that then you could just parse it yourself and use the setNanos method to store the microseconds.

We can use elasticdump to take the backup and restore it, We can move data from one server/cluster to another server/cluster.

1. Commands to move one index data from one server/cluster to another using elasticdump.

# Copy an index from production to staging with analyzer and mapping:
elasticdump \
  --input=http://production.es.com:9200/my_index \
  --output=http://staging.es.com:9200/my_index \
  --type=analyzer
elasticdump \
  --input=http://production.es.com:9200/my_index \
  --output=http://staging.es.com:9200/my_index \
  --type=mapping
elasticdump \
  --input=http://production.es.com:9200/my_index \
  --output=http://staging.es.com:9200/my_index \
  --type=data

2. Commands to move all indices data from one server/cluster to another using multielasticdump.

Backup

multielasticdump \
  --direction=dump \
  --match='^.*$' \
  --limit=10000 \
  --input=http://production.es.com:9200 \
  --output=/tmp 

Restore

multielasticdump \
  --direction=load \
  --match='^.*$' \
  --limit=10000 \
  --input=/tmp \
  --output=http://staging.es.com:9200 

Note:

• If the --direction is dump, which is the default, --input MUST be a URL for the base location of an ElasticSearch server (i.e. http://localhost:9200) and --output MUST be a directory. Each index that does match will have a data, mapping, and analyzer file created.

• For loading files that you have dumped from multi-elasticsearch, --direction should be set to load, --input MUST be a directory of a multielasticsearch dump and --output MUST be a Elasticsearch server URL.

• The 2nd command will take a backup of settings, mappings, template and data itself as JSON files.

• The --limit should not be more than 10000 otherwise, it will give an exception.

• Get more details here.

Addendum:

The proposed functions findLast...Position() do not work correctly in a scenario with a collapsing toolbar while the toolbar is expanded.

It seems that the recycler view has a fixed height, and while the toolbar is expanded, the recycler is moved down, partially out of the screen. As a consequence the results of the proposed functions are too high. Example: The last visible item is told to be #9, but in fact item #7 is the last one that is on screen.

This behaviour is also the reason why my view often failed to scroll to the correct position, i.e. scrollToPosition() did not work correctly (I finally collapsed the toolbar programmatically).

I don’t know for sure but I’m reading a book right now and what I am getting is that a program need to handle its signal ( as when I press CTRL-C). Now a program can use SIG_IGN to ignore all signals or SIG_DFL to restore the default action.

Now if you do $ command & then this process running as background process simply ignores all signals that will occur. For foreground processes these signals are not ignored.

Try setting:

android:indeterminateDrawable="@drawable/progress" 

It worked for me. Here is also the code for progress.xml:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
    android:toDegrees="360">

    <shape android:shape="ring" android:innerRadiusRatio="3"
        android:thicknessRatio="8" android:useLevel="false">

        <size android:width="48dip" android:height="48dip" />

        <gradient android:type="sweep" android:useLevel="false"
            android:startColor="#4c737373" android:centerColor="#4c737373"
            android:centerY="0.50" android:endColor="#ffffd300" />

    </shape>

</rotate> 

I guess something like this should do it. It basically writes the content to a new file and replaces the old file with the new file:

from tempfile import mkstemp
from shutil import move, copymode
from os import fdopen, remove

def replace(file_path, pattern, subst):
    #Create temp file
    fh, abs_path = mkstemp()
    with fdopen(fh,'w') as new_file:
        with open(file_path) as old_file:
            for line in old_file:
                new_file.write(line.replace(pattern, subst))
    #Copy the file permissions from the old file to the new file
    copymode(file_path, abs_path)
    #Remove original file
    remove(file_path)
    #Move new file
    move(abs_path, file_path)

In the distribution I use, the tasks are listed in the task list by default (at least for Java). For other content types, you may check the following settings.

Display the Tasks View: Window > Show View > Other > General > Tasks

For non-Java Task Tags: check the following settings: Window > Preferences > General > Editors > Structured Text Editors > Task Tags You can enable searching for task tags in the [Task Tags] tab and select the content types in the [Filters] tab.

For Java task tags, you should look in: Window > Preferences > Java > Compiler > Task Tags

With 500k documents, there is no reason to scale whatsoever. A typical laptop with an SSD and 8GB of ram can easily do 10s of millions of records, so if you are trying to pick because of scaling your choice doesn't really matter. I would suggest you pick what you like the most, and perhaps where you can find the most online support with.

Simple code that gives you the difference with multiple items if you want that:

a=[1,2,3,3,4]
b=[2,4]
tmp = copy.deepcopy(a)
for k in b:
    if k in tmp:
        tmp.remove(k)
print(tmp)

It is possible to have static class variables, but probably not worth the effort.

Here's a proof-of-concept written in Python 3 -- if any of the exact details are wrong the code can be tweaked to match just about whatever you mean by a static variable:

class Static:
    def __init__(self, value, doc=None):
        self.deleted = False
        self.value = value
        self.__doc__ = doc
    def __get__(self, inst, cls=None):
        if self.deleted:
            raise AttributeError('Attribute not set')
        return self.value
    def __set__(self, inst, value):
        self.deleted = False
        self.value = value
    def __delete__(self, inst):
        self.deleted = True

class StaticType(type):
    def __delattr__(cls, name):
        obj = cls.__dict__.get(name)
        if isinstance(obj, Static):
            obj.__delete__(name)
        else:
            super(StaticType, cls).__delattr__(name)
    def __getattribute__(cls, *args):
        obj = super(StaticType, cls).__getattribute__(*args)
        if isinstance(obj, Static):
            obj = obj.__get__(cls, cls.__class__)
        return obj
    def __setattr__(cls, name, val):
        # check if object already exists
        obj = cls.__dict__.get(name)
        if isinstance(obj, Static):
            obj.__set__(name, val)
        else:
            super(StaticType, cls).__setattr__(name, val)

and in use:

class MyStatic(metaclass=StaticType):
    """
    Testing static vars
    """
    a = Static(9)
    b = Static(12)
    c = 3

class YourStatic(MyStatic):
    d = Static('woo hoo')
    e = Static('doo wop')

and some tests:

I had this problem with no detectable lock files. I found the solution here: http://schooner.uwaterloo.ca/twiki/bin/view/MAG/HgLockError

Here is a transcript from Tortoise Hg Workbench console

% hg debuglocks
lock:  user None, process 7168, host HPv32 (114213199s)
wlock: free
[command returned code 1 Sat Jan 07 18:00:18 2017]
% hg debuglocks --force-lock
[command completed successfully Sat Jan 07 18:03:15 2017]
cmdserver: Process crashed
PaniniDev% hg debuglocks
% hg debuglocks
lock:  free
wlock: free
[command completed successfully Sat Jan 07 18:03:30 2017]

After this the aborted pull ran sucessfully.

The lock had been set more than 2 years ago, by a process on a machine that is no longer on the LAN. Shame on the hg developers for a) not documenting locks adequately; b) not timestamping them for automatic removal when they get stale.

var code = myString.Split(new [] {"code"}, StringSplitOptions.None)[1];
// code = " : -1"

You can tweak the string to split by - if you use "code : ", the second member of the returned array ([1]) will contain "-1", using your example.

For sending get request with parameter i use

  $http.get('urlPartOne\\'+parameter+'\\urlPartTwo')

By this you can use your own url string

'size_t' and 'ptrdiff_t' are required to match your architecture (whatever it is). Therefore, I think rather than using 'int', you should be able to use 'size_t', which on a 64 bit system should be a 64 bit type.

This discussion unsigned int vs size_t goes into a bit more detail.

You can use this code:

int count;
            try {
                URL url = new URL(f_url[0]);
                URLConnection conection = url.openConnection();
                conection.setConnectTimeout(TIME_OUT);
                conection.connect();
                // Getting file length
                int lenghtOfFile = conection.getContentLength();
                // Create a Input stream to read file - with 8k buffer
                InputStream input = new BufferedInputStream(url.openStream(),
                        8192);
                // Output stream to write file
                OutputStream output = new FileOutputStream(
                        "/sdcard/9androidnet.jpg");

                byte data[] = new byte[1024];
                long total = 0;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    // publishing the progress....
                    // After this onProgressUpdate will be called
                    publishProgress("" + (int) ((total * 100) / lenghtOfFile));
                    // writing data to file
                    output.write(data, 0, count);
                }
                // flushing output
                output.flush();
                // closing streams
                output.close();
                input.close();
            } catch (SocketTimeoutException e) {
                connectionTimeout=true;
            } catch (Exception e) {
                Log.e("Error: ", e.getMessage());
            }

The short answer is yes, yes there is a way to get around mysql_real_escape_string(). #For Very OBSCURE EDGE CASES!!!

The long answer isn't so easy. It's based off an attack demonstrated here.

The Attack

So, let's start off by showing the attack...

mysql_query('SET NAMES gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

In certain circumstances, that will return more than 1 row. Let's dissect what's going on here:

1. Selecting a Character Set

   mysql_query('SET NAMES gbk');
   

   For this attack to work, we need the encoding that the server's expecting on the connection both to encode ' as in ASCII i.e. 0x27 and to have some character whose final byte is an ASCII \ i.e. 0x5c. As it turns out, there are 5 such encodings supported in MySQL 5.6 by default: big5, cp932, gb2312, gbk and sjis. We'll select gbk here.

   Now, it's very important to note the use of SET NAMES here. This sets the character set ON THE SERVER. If we used the call to the C API function mysql_set_charset(), we'd be fine (on MySQL releases since 2006). But more on why in a minute...

2. The Payload

   The payload we're going to use for this injection starts with the byte sequence 0xbf27. In gbk, that's an invalid multibyte character; in latin1, it's the string ¿'. Note that in latin1 and gbk, 0x27 on its own is a literal ' character.

   We have chosen this payload because, if we called addslashes() on it, we'd insert an ASCII \ i.e. 0x5c, before the ' character. So we'd wind up with 0xbf5c27, which in gbk is a two character sequence: 0xbf5c followed by 0x27. Or in other words, a valid character followed by an unescaped '. But we're not using addslashes(). So on to the next step...

3. mysql_real_escape_string()

   The C API call to mysql_real_escape_string() differs from addslashes() in that it knows the connection character set. So it can perform the escaping properly for the character set that the server is expecting. However, up to this point, the client thinks that we're still using latin1 for the connection, because we never told it otherwise. We did tell the server we're using gbk, but the client still thinks it's latin1.

   Therefore the call to mysql_real_escape_string() inserts the backslash, and we have a free hanging ' character in our "escaped" content! In fact, if we were to look at $var in the gbk character set, we'd see:

   ?' OR 1=1 /*

   Which is exactly what the attack requires.

4. The Query

   This part is just a formality, but here's the rendered query:

   SELECT * FROM test WHERE name = '?' OR 1=1 /*' LIMIT 1
   

Congratulations, you just successfully attacked a program using mysql_real_escape_string()...

The Bad

It gets worse. PDO defaults to emulating prepared statements with MySQL. That means that on the client side, it basically does a sprintf through mysql_real_escape_string() (in the C library), which means the following will result in a successful injection:

$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Now, it's worth noting that you can prevent this by disabling emulated prepared statements:

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

This will usually result in a true prepared statement (i.e. the data being sent over in a separate packet from the query). However, be aware that PDO will silently fallback to emulating statements that MySQL can't prepare natively: those that it can are listed in the manual, but beware to select the appropriate server version).

The Ugly

I said at the very beginning that we could have prevented all of this if we had used mysql_set_charset('gbk') instead of SET NAMES gbk. And that's true provided you are using a MySQL release since 2006.

If you're using an earlier MySQL release, then a bug in mysql_real_escape_string() meant that invalid multibyte characters such as those in our payload were treated as single bytes for escaping purposes even if the client had been correctly informed of the connection encoding and so this attack would still succeed. The bug was fixed in MySQL 4.1.20, 5.0.22 and 5.1.11.

But the worst part is that PDO didn't expose the C API for mysql_set_charset() until 5.3.6, so in prior versions it cannot prevent this attack for every possible command! It's now exposed as a DSN parameter.

The Saving Grace

As we said at the outset, for this attack to work the database connection must be encoded using a vulnerable character set. utf8mb4 is not vulnerable and yet can support every Unicode character: so you could elect to use that instead—but it has only been available since MySQL 5.5.3. An alternative is utf8, which is also not vulnerable and can support the whole of the Unicode Basic Multilingual Plane.

Alternatively, you can enable the NO_BACKSLASH_ESCAPES SQL mode, which (amongst other things) alters the operation of mysql_real_escape_string(). With this mode enabled, 0x27 will be replaced with 0x2727 rather than 0x5c27 and thus the escaping process cannot create valid characters in any of the vulnerable encodings where they did not exist previously (i.e. 0xbf27 is still 0xbf27 etc.)—so the server will still reject the string as invalid. However, see @eggyal's answer for a different vulnerability that can arise from using this SQL mode.

Safe Examples

The following examples are safe:

mysql_query('SET NAMES utf8');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because the server's expecting utf8...

mysql_set_charset('gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because we've properly set the character set so the client and the server match.

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've turned off emulated prepared statements.

$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=gbk', $user, $password);
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've set the character set properly.

$mysqli->query('SET NAMES gbk');
$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "\xbf\x27 OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

Because MySQLi does true prepared statements all the time.

Wrapping Up

If you:

• Use Modern Versions of MySQL (late 5.1, all 5.5, 5.6, etc) AND mysql_set_charset() / $mysqli->set_charset() / PDO's DSN charset parameter (in PHP = 5.3.6)

OR

• Don't use a vulnerable character set for connection encoding (you only use utf8 / latin1 / ascii / etc)

You're 100% safe.

Otherwise, you're vulnerable even though you're using mysql_real_escape_string()...

faster way will require additional space .

For example:

1. put all items in one list into a HashSet ( you have to implement the hash function by yourself to use object.getAttributeSame() )

2. Go through the other list and check if any item is in the HashSet.

In this way each object is visited at most once. and HashSet is fast enough to check or insert any object in O(1).

ASP.NET Core

Routing is configured in the Configure method of the Startup class. To set the "homepage" simply add the following. This will cause users to be routed to the controller and action defined in the MapRoute method when/if they navigate to your site’s base URL, i.e., yoursite.com will route users to yoursite.com/foo/index:

app.UseMvc(routes =>
{
   routes.MapRoute(
   name: "default",
   template: "{controller=FooController}/{action=Index}/{id?}");
});

Pre-ASP.NET Core

Use the RegisterRoutes method located in either App_Start/RouteConfig.cs (MVC 3 and 4) or Global.asax.cs (MVC 1 and 2) as shown below. This will cause users to be routed to the controller and action defined in the MapRoute method if they navigate to your site’s base URL, i.e., yoursite.com will route the user to yoursite.com/foo/index:

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    // Here I have created a custom "Default" route that will route users to the "YourAction" method within the "FooController" controller.
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "FooController", action = "Index", id = UrlParameter.Optional }
    );
}

If you are using Ubuntu 18.04 along with Python 3.6, then pip or pip3 won't help. You need to install tkinter using following command:

sudo apt-get install python3-tk

Here is another way:

//Acsending
case "SUP_APPROVED_IND": qry =
                            qry.OrderBy(r => r.SUP_APPROVED_IND.Trim() == null).
                                    ThenBy(r => r.SUP_APPROVED_IND);

                            break;
//….
//Descending
case "SUP_APPROVED_IND": qry =
                            qry.OrderBy(r => r.SUP_APPROVED_IND.Trim() == null).
                                    ThenByDescending(r => r.SUP_APPROVED_IND); 

                            break;

SUP_APPROVED_IND is char(1) in Oracle db.

Note that r.SUP_APPROVED_IND.Trim() == null is treated as trim(SUP_APPROVED_IND) is null in Oracle db.

I know it's been a year since this was asked, but just for people that are going to visit this page I am posting my solution.

By using what @Aldi Unanto suggested here is a more complete answer:

  jQuery('.show_hide').click(function(e) {
    e.preventDefault();
    if (jQuery('.slidingDiv').is(":visible") ) {
      jQuery('.slidingDiv').stop(true,true).hide("slide", { direction: "left" }, 200);
    } else {
      jQuery('.slidingDiv').stop(true,true).show("slide", { direction: "left" }, 200);
    }
  });

First I prevent the link from doing anything on click. Then I add a check if the element is visible or not. When visible I hide it. When hidden I show it. You can change direction to left or right and duration from 200 ms to anything you like.

Edit: I have also added

.stop(true,true)

in order to clearQueue and jumpToEnd. Read about jQuery stop here

You could get rid of all the letters too:

as.numeric(gsub("[[:alpha:]]", "", years))

Likely this is less generalizable though.

Try using Web API HttpClient

    static async Task RunAsync()
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://domain.com/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


            // HTTP POST
            var obj = new MyObject() { Str = "MyString"};
            response = await client.PostAsJsonAsync("POST URL GOES HERE?", obj );
            if (response.IsSuccessStatusCode)
            {
                response.//.. Contains the returned content.
            }
        }
    }

Open a good text editor (I'd recommend TextMate, but the free TextWrangler or vi or nano will do too), and open:

/etc/apache2/httpd.conf

Find the line:

"#LoadModule php5_module        libexec/apache2/libphp5.so"

And uncomment it (remove the #).

Download and install the latest MySQL version from mysql.com. Choose the x86_64 version for Intel (unless your Intel Mac is the original Macbook Pro or Macbook, which are not 64 bit chips. In those cases, use the 32 bit x86 version).

Install all the MySQL components. Using the pref pane, start MySQL.

In the Sharing System Pref, turn on (or if it was already on, turn off/on) Web Sharing.

You should now have Apache/PHP/MySQL running.

In 10.4 and 10.5 it was necessary to modify the php.ini file to point to the correct location of mysql.sock. There are reports that this is fixed in 10.6, but that doesn't appear to be the case for all of us, given some of the comments below.

Renaming .bashrc to .profile (or soft-linking the latter to the former) should also do the trick. See here.

Regex.Split("abc][rfd][5][,][.", @"\]\]");

ini_set('magic_quotes_runtime', 0)

I guess.

Using DISTINCT will work

SELECT GROUP_CONCAT(DISTINCT(categories) SEPARATOR ' ') FROM table

REf:- this

With sed on dash shell of LANG=en_US.UTF-8, I got the followings working right:

$ echo "??? ????????" | sed -e 's/\(.\)/\1\n/g'

and

$ echo "Hello world" | sed -e 's/\(.\)/\1\n/g'
H
e

Thus, output can be looped with while read ... ; do ... ; done

edited for sample text translate into English:

"??? ????????" is zh_TW.UTF-8 encoding for:
"???"     = How are you[ doing]
" "         = a normal space character
"???"     = Happy new year
"?????" = a double-byte-sized full-stop followed by text description

I am late to this one by a while, but I'm going to blow your mind, ready?

The reason this is happening, is because you are calling bootstrap in, after you are calling jquery-ui in.

Literally, swap the two so that instead of:

<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script src="js/bootstrap.min.js"></script>

it becomes

<script src="js/bootstrap.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>

:)

Edit - 26/06/2015 - this keeps attracting interest months later so I thought it was worth an edit. I actually really like the noConflict solution offered in the comment underneath this answer and clarified by user Pretty Cool as a separate answer. As some have reported issues with the bootstrap tooltip when the scripts are swapped. I didn't experience that issue however because I downloaded jquery UI without the tooltip as I didn't need it because bootstrap. So this issue never came up for me.

Edit - 22/07/2015 - Don't confuse jquery-ui with jquery! While Bootstrap's JavaScript requires jQuery to be loaded before, it doesn't rely on jQuery-UI. So jquery-ui.js can be loaded after bootstrap.min.js, while jquery.js always needs to be loaded before Bootstrap.

You can also use

border-left: 9vw solid #F5E5D6;
border-right: 9vw solid #F5E5D6;     

OR

border: 9vw solid #F5E5D6;

You can always try this:

/home/user/anaconda3/bin/pip install -r requirements.txt

This simply uses the pip installed in the conda environment. If pip is not preinstalled in your environment you can always run the following command

conda install pip

You can use code snippets to insert any lines you want.

Also, if you type three single quotation marks (''') on the line above the function header, it will insert the XML header template that you can then fill out.

These XML comments can be interpreted by documentation software, and they are included in the build output as an assembly.xml file. If you keep that XML file with the DLL and reference that DLL in another project, those comments become available in intellisense.

always use with statement like ;WITH then you'll never get this error. The WITH command required a ; between it and any previous command, by always using ;WITH you'll never have to remember to do this.

see WITH common_table_expression (Transact-SQL), from the section Guidelines for Creating and Using Common Table Expressions:

When a CTE is used in a statement that is part of a batch, the statement before it must be followed by a semicolon.

The installation of CuDNN is just copying some files. Hence to check if CuDNN is installed (and which version you have), you only need to check those files.

Install CuDNN

Step 1: Register an nvidia developer account and download cudnn here (about 80 MB). You might need nvcc --version to get your cuda version.

Step 2: Check where your cuda installation is. For most people, it will be /usr/local/cuda/. You can check it with which nvcc.

Step 3: Copy the files:

$ cd folder/extracted/contents
$ sudo cp include/cudnn.h /usr/local/cuda/include
$ sudo cp lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

Check version

You might have to adjust the path. See step 2 of the installation.

$ cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

Notes

When you get an error like

F tensorflow/stream_executor/cuda/cuda_dnn.cc:427] could not set cudnn filter descriptor: CUDNN_STATUS_BAD_PARAM

with TensorFlow, you might consider using CuDNN v4 instead of v5.

Just add my answer in addition to Nigel Kirby's as I can't comment yet:

In order to pass a dynamically created parameter, you can also export the variable in 'Execute Shell' tile and then pass it through 'Trigger parameterized build on other projects' => 'Predefined parameters" => give 'YOUR_VAR=$YOUR_VAR'. My team use this feature to pass npm package version from build job to deployment jobs

UPDATE: above only works for Jenkins injected parameters, parameter created from shell still need to use same method. eg. echo YOUR_VAR=${YOUR_VAR} > variable.properties and pass that file downstream

You can use the "New Class" dialog, but that leaves other steps you need to do by hand (e.g. adding an entry to the manifest file). If you want those steps to be automated, you can create the activity via the manifest editor like this:

1. Double click on AndroidManifest.xml in the package explorer.
2. Click on the "Application" tab of the manifest editor
3. Click on "Add.." under the "Application Nodes" heading (bottom left of the screen)
4. Choose Activity from the list in the dialog that pops up (if you have the option, you want to create a new top-level element)
5. Click on the "Name*" link under the "Attributes for" header (bottom right of the window) to create a class for the new activity.

When you click Finish from the new class dialog, it'll take you to your new activity class so you can start coding.

Five steps might seem a lot, but I'm just trying to be extra detailed here so that it's clear. It's pretty quick when you actually do it.

instanceof is a keyword that can be used to test if an object is of a specified type.

Example :

public class MainClass {
    public static void main(String[] a) {

    String s = "Hello";
    int i = 0;
    String g;
    if (s instanceof java.lang.String) {
       // This is going to be printed
       System.out.println("s is a String");
    }
    if (i instanceof Integer) {
       // This is going to be printed as autoboxing will happen (int -> Integer)
       System.out.println("i is an Integer");
    }
    if (g instanceof java.lang.String) {
       // This case is not going to happen because g is not initialized and
       // therefore is null and instanceof returns false for null. 
       System.out.println("g is a String");
    } 
}
