this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

Best command is: tree -fi

-f print the full path prefix for each file
-i don't print indentations

e.g.

$ tree -fi
.
./README.md
./node_modules
./package.json
./src
./src/datasources
./src/datasources/bookmarks.js
./src/example.json
./src/index.js
./src/resolvers.js
./src/schema.js

In order to use the files but not the links, you have to remove > from your output:

tree -fi |grep -v \>

If you want to know the nature of each file, (to read only ASCII files for example) with two whiles:

tree -fi | \
grep -v \> | \
while read first ; do 
    file ${first}
done | \
while read second; do 
    echo ${second} | grep ASCII
done

Use the command dir to list all the directories and files in a directory; ls is a unix command.

you could add an sed script to your commandline:

ls /home/user/new/*.txt | sed -r 's/^.+\///'

By default ls -t sorts output from newest to oldest, so the combination of commands to use depends in which direction you want your output to be ordered.

For the newest 5 files ordered from newest to oldest, use head to take the first 5 lines of output:

ls -t | head -n 5

For the newest 5 files ordered from oldest to newest, use the -r switch to reverse ls's sort order, and use tail to take the last 5 lines of output:

ls -tr | tail -n 5

Try this one:

find . -type f -printf "%T@ %p\n" | sort -nr | cut -d\  -f2-

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

If you want to use Unix shell commands on Windows, you can use Windows Powershell, which includes both Windows and Unix commands as aliases. You can find more info on it in the documentation.

PowerShell supports aliases to refer to commands by alternate names. Aliasing allows users with experience in other shells to use common command names that they already know for similar operations in PowerShell.

The PowerShell equivalents may not produce identical results. However, the results are close enough that users can do work without knowing the PowerShell command name.

This would print the files in those directories line by line.

array=(ww/* ee/* qq/*)
printf "%s\n" "${array[@]}"

ls | tr "" "\n"

That does the trick:

ls -R1 $PWD | while read l; do case $l in *:) d=${l%:};; "") d=;; *) echo "$d/$l";; esac; done | grep -i ".txt"

But it does that by "sinning" with the parsing of ls, though, which is considered bad form by the GNU and Ghostscript communities.

To search and delete empty files in the current directory and subdirectories:

find . -type f -empty -delete

-type f is necessary because also directories are marked to be of size zero.

The dot . (current directory) is the starting search directory. If you have GNU find (e.g. not Mac OS), you can omit it in this case:

find -type f -empty -delete

From GNU find documentation:

If no files to search are specified, the current directory (.) is used.

If you give the find command an absolute path, it will spit the results out with an absolute path. So, from the Ken directory if you were to type:

find /home/ken/foo/ -name bar -print    

(instead of the relative path find . -name bar -print)

You should get:

/home/ken/foo/bar

Therefore, if you want an ls -l and have it return the absolute path, you can just tell the find command to execute an ls -l on whatever it finds.

find /home/ken/foo -name bar -exec ls -l {} ;\ 

NOTE: There is a space between {} and ;

You'll get something like this:

-rw-r--r--   1 ken admin       181 Jan 27 15:49 /home/ken/foo/bar

If you aren't sure where the file is, you can always change the search location. As long as the search path starts with "/", you will get an absolute path in return. If you are searching a location (like /) where you are going to get a lot of permission denied errors, then I would recommend redirecting standard error so you can actually see the find results:

find / -name bar -exec ls -l {} ;\ 2> /dev/null

(2> is the syntax for the Borne and Bash shells, but will not work with the C shell. It may work in other shells too, but I only know for sure that it works in Bourne and Bash).

My ls sorts by name by default. What are you seeing?

man ls states:

List information about the FILEs (the current directory by default). Sort entries alpha-betically if none of -cftuvSUX nor --sort is specified.:

Here is a variation using tree which outputs directory names only on separate lines, yes it's ugly, but hey, it works.

tree -d | grep -E '^[+|+]' | cut -d ' ' -f2

or with awk

tree -d | grep -E '^[+|+]' | awk '{print $2}'

This is probably better however and will retain the / after directory name.

ls -l | grep "^d" | awk '{print $9}'

I wrote a shell script called fullpath that contains this code, use it everyday:

    #!/bin/sh
    for i in $* ; do
        echo $(pwd)/$i
    done

Put it somewhere in your PATH, and make it executable(chmod 755 fullpath) then just use
fullpath file_or_directory

Try the arrow module from http://crsmithdev.com/arrow/:

import arrow
arrow.now()

Or the UTC version:

arrow.utcnow()

To change its output, add .format():

arrow.utcnow().format('YYYY-MM-DD HH:mm:ss ZZ')

For a specific timezone:

arrow.now('US/Pacific')

An hour ago:

arrow.utcnow().replace(hours=-1)

Or if you want the gist.

arrow.get('2013-05-11T21:23:58.970460+00:00').humanize()
>>> '2 years ago'

Not sure if this is what you're after, but it will loop through the range that you gave it and if it finds an "A" it will remove it from the cell. I'm not sure what oldStr is used for...

Private Sub foo()
Dim myString As String
RowCount = WorksheetFunction.CountA(Range("A:A"))

For i = 2 To RowCount
    myString = Trim(Cells(i, 1).Value)
    If InStr(myString, "A") > 0 Then
        Cells(i, 1).Value = Left(myString, InStr(myString, "A"))
    End If
Next
End Sub

There are many articles about writing code to import an excel file, but this is a manual/shortcut version:

If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.

The quickest way to get your Excel file into SQL is by using the import wizard:

1. Open SSMS (Sql Server Management Studio) and connect to the database where you want to import your file into.
2. Import Data: in SSMS in Object Explorer under 'Databases' right-click the destination database, select Tasks, Import Data. An import wizard will pop up (you can usually just click 'Next' on the first screen).

3. The next window is 'Choose a Data Source', select Excel:

   • In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).

   • Click the 'Browse' button to select the path to the Excel file you want to import.

   • Select the version of the excel file (97-2003 is usually fine for files with a .XLS extension, or use 2007 for newer files with a .XLSX extension)
   • Tick the 'First Row has headers' checkbox if your excel file contains headers.
   • Click next.

4. On the 'Choose a Destination' screen, select destination database:
   • Select the 'Server name', Authentication (typically your sql username & password) and select a Database as destination. Click Next.

5. On the 'Specify Table Copy or Query' window:

   • For simplicity just select 'Copy data from one or more tables or views', click Next.

6. 'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.

7. Click Finish.

Around 1:51 in the video, notice how she puts a <script> tag in there? The way it works is like this:

Create an html file (that's just a text file with a .html ending) somewhere on your computer. In the same folder that you put index.html, put a javascript file (that's just a textfile with a .js ending - let's call it game.js). Then, in your index.html file, put some html that includes the script tag with game.js, like Mary did in the video. index.html should look something like this:

<html>
    <head>
        <script src="game.js"></script>
    </head>
</html>

Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).

Good luck on your journey, hope it's as fun for you as it has been for me so far :)

Non of the above answers worked for me so here is what I did eventually:

import React, { Component } from 'react';

/**
 * Component that alerts if you click outside of it
 */
export default class OutsideAlerter extends Component {
  constructor(props) {
    super(props);

    this.handleClickOutside = this.handleClickOutside.bind(this);
  }

  componentDidMount() {
    document.addEventListener('mousedown', this.handleClickOutside);
  }

  componentWillUnmount() {
    document.removeEventListener('mousedown', this.handleClickOutside);
  }

  /**
   * Alert if clicked on outside of element
   */
  handleClickOutside(event) {
    if (!event.path || !event.path.filter(item => item.className=='classOfAComponent').length) {
      alert('You clicked outside of me!');
    }
  }

  render() {
    return <div>{this.props.children}</div>;
  }
}

OutsideAlerter.propTypes = {
  children: PropTypes.element.isRequired,
};

These days listen for oninput. It feels like onchange without the need to lose focus on the element. It is HTML5.

It’s supported by everyone (even mobile), except IE8 and below. For IE add onpropertychange. I use it like this:

const source = document.getElementById('source');_x000D_
const result = document.getElementById('result');_x000D_
_x000D_
const inputHandler = function(e) {_x000D_
  result.innerHTML = e.target.value;_x000D_
}_x000D_
_x000D_
source.addEventListener('input', inputHandler);_x000D_
source.addEventListener('propertychange', inputHandler); // for IE8_x000D_
// Firefox/Edge18-/IE9+ don’t fire on <select><option>_x000D_
// source.addEventListener('change', inputHandler); 

<input id="source">_x000D_
<div id="result"></div>

You will not be able to capitalize the first word of each sentence with CSS.

CSS offers text-transform for capitalization, but it only supports capitalize, uppercase and lowercase. None of these will do what you want. You can make use of the selector :first-letter, which will apply any style to the first letter of an element - but not of the subsequent ones.

p {
    text-transform: lowercase;
}
p:first-letter {
    text-transform: capitalize;
}

<p>SAMPLE TEXT. SOME SENTENCE. SOMETHING ELSE</p>
<!-- will become this:
Sample text. some sentence. something else. -->

That is not what you want (and :first-letter is not cross-browser compatible... IE again).
The only way to do what you want is with a kind of programming language (serverside or clientside), like Javascript or PHP. In PHP you have the ucwords function (documented here), which just like CSS capitalizes each letter of each word, but doing some programming magic (check out the comments of the documentation for references), you are able to achieve capitalization of each first letter of each sentence.

The easier solution and you might not want to do PHP is using Javascript. Check out the following page - Capital Letters - for a full blown Javascript example of doing exactly what you want. The Javascript is pretty short and does the capitalization with some String manipulation - you will have no problem adjusting the capitalize-sentences.js to your needs.

In any case: Capitalization should usually be done in the content itself not via Javascript or markup languages. Consider cleaning up your content (your texts) with other means. Microsoft Word for example has built in functions to do just what you want.

If NEW_TABLE already exists then ...

insert into new_table 
select * from old_table
/

If you want to create NEW_TABLE based on the records in OLD_TABLE ...

create table new_table as 
select * from old_table
/

If the purpose is to create a new but empty table then use a WHERE clause with a condition which can never be true:

create table new_table as 
select * from old_table
where 1 = 2
/

Remember that CREATE TABLE ... AS SELECT creates only a table with the same projection as the source table. The new table does not have any constraints, triggers or indexes which the original table might have. Those still have to be added manually (if they are required).

Since Spring 3.0 you can use @Primary annotation. As per documentation:

Indicates that a bean should be given preference when multiple candidates are qualified to autowire a single-valued dependency. If exactly one 'primary' bean exists among the candidates, it will be the autowired value. This annotation is semantically equivalent to the element's primary attribute in Spring XML.

You should use it on Bean definition like this:

@Bean
@Primary
public ExampleBean exampleBean(@Autowired EntityManager em) {
    return new ExampleBeanImpl(em);
}

or like this:

@Primary
@Service
public class ExampleService implements BaseServive {
}

Once you have your Context and know the name of the database, use:

context.deleteDatabase(DATABASE_NAME);

When this line gets run, the database should be deleted.

Nothing works in my case using the scripts above but I was able to close these figures from eclipse console bar by clicking on Terminate ALL (two red nested squares icon).

There are few answers here indicating both strategies for 2 different versions of Jackson library below:

For Jackson 2.6.*

ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
     PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);

For Jackson 2.7.*

ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
     PropertyNamingStrategy.SNAKE_CASE);

Add permission to your Manifest file.

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

• Remove the file from the index, but keep it versioned and left with uncommitted changes in working copy:

  git reset head <file>
  

• Reset the file to the last state from HEAD, undoing changes and removing them from the index:

  git reset HEAD <file>
  git checkout <file>
  
  # If you have a `<branch>` named like `<file>`, use:
  git checkout -- <file>
  

  This is needed since git reset --hard HEAD won't work with single files.

• Remove <file> from index and versioning, keeping the un-versioned file with changes in working copy:

  git rm --cached <file>
  

• Remove <file> from working copy and versioning completely:

  git rm <file>
  

There is nothing built in afaik, but building it yourself should be easy. I would do as you suggest and use reflection to obtain the properties and use them to create the columns of the table. Then I would step through each item in the IEnumerable and create a row for each. The only caveat is if your collection contains items of several types (say Person and Animal) then they may not have the same properties. But if you need to check for it depends on your use.

My mistake was that I was creating classes in resource package...

Creating classes in src/main/java solved the issue.

Per sys.hexversion and API and ABI Versioning:

import sys
if sys.hexversion >= 0x3000000:
    print('Python 3.x hexversion %s is in use.' % hex(sys.hexversion))

Posted this in a similar thread, but thought it might be relevant here as well.

Achieving this with a single instance of jQuery-UI Accordion

As others have noted, the Accordion widget does not have an API option to do this directly. However, if for some reason you must use the widget (e.g. you're maintaining an existing system), it is possible to achieve this by using the beforeActivate event handler option to subvert and emulate the default behavior of the widget.

For example:

$('#accordion').accordion({
    collapsible:true,

    beforeActivate: function(event, ui) {
         // The accordion believes a panel is being opened
        if (ui.newHeader[0]) {
            var currHeader  = ui.newHeader;
            var currContent = currHeader.next('.ui-accordion-content');
         // The accordion believes a panel is being closed
        } else {
            var currHeader  = ui.oldHeader;
            var currContent = currHeader.next('.ui-accordion-content');
        }
         // Since we've changed the default behavior, this detects the actual status
        var isPanelSelected = currHeader.attr('aria-selected') == 'true';

         // Toggle the panel's header
        currHeader.toggleClass('ui-corner-all',isPanelSelected).toggleClass('accordion-header-active ui-state-active ui-corner-top',!isPanelSelected).attr('aria-selected',((!isPanelSelected).toString()));

        // Toggle the panel's icon
        currHeader.children('.ui-icon').toggleClass('ui-icon-triangle-1-e',isPanelSelected).toggleClass('ui-icon-triangle-1-s',!isPanelSelected);

         // Toggle the panel's content
        currContent.toggleClass('accordion-content-active',!isPanelSelected)    
        if (isPanelSelected) { currContent.slideUp(); }  else { currContent.slideDown(); }

        return false; // Cancels the default action
    }
});

See a jsFiddle demo

First Method

when you want to open a video in full screen for that Activity you have to set the theme attribute in the Manifest. set this value that is

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

change theme programmatically here

Second Method

create another fullscreen.xml like below and setContentView(R.layout.fullscreen) on click of the button

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

    <VideoView android:id="@+id/myvideoview"
        android:layout_width="fill_parent"
        android:layout_alignParentRight="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>

From the doc for path.resolve:

The resulting path is normalized and trailing slashes are removed unless the path is resolved to the root directory.

But path.join keeps trailing slashes

So

__dirname = '/';
path.resolve(__dirname, 'foo/'); // '/foo'
path.join(__dirname, 'foo/'); // '/foo/'

If your string will always be of that format, a regex is overkill:

>>> var g='{getThis}';
>>> g.substring(1,g.length-1)
"getThis"

substring(1 means to start one character in (just past the first {) and ,g.length-1) means to take characters until (but not including) the character at the string length minus one. This works because the position is zero-based, i.e. g.length-1 is the last position.

For readers other than the original poster: If it has to be a regex, use /{([^}]*)}/ if you want to allow empty strings, or /{([^}]+)}/ if you want to only match when there is at least one character between the curly braces. Breakdown:

• /: start the regex pattern
  • {: a literal curly brace
    • (: start capturing
      • [: start defining a class of characters to capture
        • ^}: "anything other than }"
      • ]: OK, that's our whole class definition
      • *: any number of characters matching that class we just defined
    • ): done capturing
  • }: a literal curly brace must immediately follow what we captured
• /: end the regex pattern

Just remove the .val(). Like:

if ( $('html').attr('lang') == 'fr-FR' ) {
    // do this
} else {
    // do that
}

Have you tried SELECT DISTINCT ?

INSERT INTO destTable
SELECT DISTINCT * FROM srcTable

Mac users:

1. Go to System Preferences -> Network -> Wi-Fi
2. Copy the IP address below Status (Usually 192.168.1.x)
3. Paste it in your ng serve like: ng serve --host 192.168.1.x

Then you must be able to see your page on other devices through 192.168.1.x:4200.

Very simple code to make jquery slider Here is two div first is the slider viewer and second is the image list container. Just copy paste the code and customise with css.

I'm the one who donated the Ant export filter to Eclipse. I added the auto export feature, but only to my personal plug-in eclipse2ant, which I still maintain to coordinate bug fixes.

Unfortunately I have no time to merge it to the official Eclipse builds.

Did you forget the Background Property. The brush should be an ImageBrush whose ImageSource could be set to your image path.

<Grid>
    <Grid.Background>
        <ImageBrush ImageSource="/path/to/image.png" Stretch="UniformToFill"/>
    </Grid.Background>

    <...>
</Grid>

I just came across one use case that I had to use var over let to introduce new variable. Here's a case:

I want to create a new variable with dynamic variable names.

let variableName = 'a';
eval("let " + variableName + '= 10;');
console.log(a);   // this doesn't work

var variableName = 'a';
eval("var " + variableName + '= 10;');
console.log(a);   // this works

The above code doesn't work because eval introduces a new block of code. The declaration using var will declare a variable outside of this block of code since var declares a variable in the function scope.

let, on the other hand, declares a variable in a block scope. So, a variable will only be visible in eval block.

I was facing the same issue every time I have to kill the port.

I tried ./node_modules/.bin/ng serve --proxy-config proxy.conf.json --host 0.0.0.0 Instead of npm start and its works

Maybe I'm missing something here... but if you want the present working directory you can just use this: (Get-Location).Path for a string, or Get-Location for an object.

Unless you're referring to something like this, which I understand after reading the question again.

function Get-Script-Directory
{
    $scriptInvocation = (Get-Variable MyInvocation -Scope 1).Value
    return Split-Path $scriptInvocation.MyCommand.Path
}

Putting the model dot property in strings worked for me: ModelState.AddModelError("Item1.Month", "This is not a valid date");

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

It's not generally correct that you can "remove an item from a database" with both methods. To be precise it is like so:

• ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

• EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

  • If the relationship is optional, i.e. the foreign key that refers from the child to the parent in the database allows NULL values, this foreign will be set to null and if you call SaveChanges this NULL value for the childEntity will be written to the database (i.e. the relationship between the two is removed). This happens with a SQL UPDATE statement. No DELETE statement occurs.

  • If the relationship is required (the FK doesn't allow NULL values) and the relationship is not identifying (which means that the foreign key is not part of the child's (composite) primary key) you have to either add the child to another parent or you have to explicitly delete the child (with DeleteObject then). If you don't do any of these a referential constraint is violated and EF will throw an exception when you call SaveChanges - the infamous "The relationship could not be changed because one or more of the foreign-key properties is non-nullable" exception or similar.

  • If the relationship is identifying (it's necessarily required then because any part of the primary key cannot be NULL) EF will mark the childEntity as Deleted as well. If you call SaveChanges a SQL DELETE statement will be sent to the database. If no other referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

I am actually a bit confused about the Remarks section on the MSDN page you have linked because it says: "If the relationship has a referential integrity constraint, calling the Remove method on a dependent object marks both the relationship and the dependent object for deletion.". This seems unprecise or even wrong to me because all three cases above have a "referential integrity constraint" but only in the last case the child is in fact deleted. (Unless they mean with "dependent object" an object that participates in an identifying relationship which would be an unusual terminology though.)

Use below code snippet This worked for me

ObjectMapper objectMapper = new ObjectMapper();
String jsonString = "{\"symbol\":\"ABCD\}";
objectMapper.configure(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true);
Trade trade = objectMapper.readValue(jsonString, new TypeReference<Symbol>() {});

Model Class

@JsonIgnoreProperties    public class Symbol {
    @JsonProperty("symbol")
    private String symbol;
}

To toggle a checkbox or you can use

element.checked = !element.checked;

so you could use

if (attribute == elementName)
{
    arrChecks[i].checked = !arrChecks[i].checked;
} else {
    arrChecks[i].checked = false;
}

I had this same issue. I was doing

arr = []
arr.append["HI"]

So using [ was causing error. It should be arr.append("HI")

For those who came here looking for a way to download a blob url video / audio, this answer worked for me. In short, you would need to find an *.m3u8 file on the desired web page through Chrome -> Network tab and paste it into a VLC player.

Another guide shows you how to save a stream with the VLC Player.

Because @pythonlarry asked here are the missing generator based versions

The groupby join is easy. Groupby will group elements consecutive with same key. And return pairs of keys and list of elements for each group. So when the key is an space an space is returne else the entire group.

from itertools import groupby
def group_join(string):
  return ''.join(' ' if chr==' ' else ''.join(times) for chr,times in groupby(string))

The group by variant is simple but very slow. So now for the generator variant. Here we consume an iterator, the string, and yield all chars except chars that follow an char.

def generator_join_generator(string):
  last=False
  for c in string:
    if c==' ':
      if not last:
        last=True
        yield ' '
    else:
      last=False
    yield c

def generator_join(string):
  return ''.join(generator_join_generator(string))

You have to check every ID in tableA against every ID in tableB. A fully featured RDBMS (such as Oracle) would be able to optimize that into an INDEX FULL FAST SCAN and not touch the table at all. I don't know whether H2's optimizer is as smart as that.

H2 does support the MINUS syntax so you should try this

select id from tableA
minus
select id from tableB
order by id desc

That may perform faster; it is certainly worth benchmarking.

if ( condition ) {
    return;
}

The return exits the function returning undefined.

The exit statement doesn't exist in javascript.

The break statement allows you to exit a loop, not a function. For example:

var i = 0;
while ( i < 10 ) {
    i++;
    if ( i === 5 ) {
        break;
    }
}

This also works with the for and the switch loops.

Short version: Yes it is faster, with less code!

String concatenation does a lot of work without knowing if it is needed or not (the traditional "is debugging enabled" test known from log4j), and should be avoided if possible, as the {} allows delaying the toString() call and string construction to after it has been decided if the event needs capturing or not. By having the logger format a single string the code becomes cleaner in my opinion.

You can provide any number of arguments. Note that if you use an old version of sljf4j and you have more than two arguments to {}, you must use the new Object[]{a,b,c,d} syntax to pass an array instead. See e.g. http://slf4j.org/apidocs/org/slf4j/Logger.html#debug(java.lang.String, java.lang.Object[]).

Regarding the speed: Ceki posted a benchmark a while back on one of the lists.

Here is the right anwser:

ADD_EXECUTABLE(your_executable ${source_files})

TARGET_LINK_LIBRARIES( your_executable
pthread
)

equivalent to

-lpthread

If you want to find out only whether or not the files are identical, you can use the Windows fc command in binary mode:

fc.exe /b file1 file2

For details, see the reference for fc

Using Apache Commons Lang:

!StringUtils.isAlphanumeric(String)

Alternativly iterate over String's characters and check with:

!Character.isLetterOrDigit(char)

You've still one problem left: Your example string "abcdefà" is alphanumeric, since à is a letter. But I think you want it to be considered non-alphanumeric, right?!

So you may want to use regular expression instead:

String s = "abcdefà";
Pattern p = Pattern.compile("[^a-zA-Z0-9]");
boolean hasSpecialChar = p.matcher(s).find();

I was having a problem with ASP.NET MVC 5 where CheckBoxFor would not check my checkboxes on server-side validation failure even though my model clearly had the value set to true. My Razor markup/code looked like:

@Html.CheckBoxFor(model => model.MyBoolValue, new { @class = "mySpecialClass" } )

To get this to work, I had to change this to:

@{
    var checkboxAttributes = Model.MyBoolValue ?
        (object) new { @class = "mySpecialClass", @checked = "checked" } :
        (object) new { @class = "mySpecialClass" };
}
@Html.CheckBox("MyBoolValue", checkboxAttributes)

As of Gradle 4.9 Application plugin understands --args option, so passing the arguments is as simple as:

build.gradle

plugins {
    id 'application'
}

mainClassName = "my.App"

src/main/java/my/App.java

public class App {
    public static void main(String[] args) {
        System.out.println(args);
    }
}

bash

./gradlew run --args='This string will be passed into my.App#main arguments'

or in Windows, use double quotes:

gradlew run --args="This string will be passed into my.App#main arguments"

From the screenshot I can see that you want to pass "user" and "password" values to the service. You have send the parameter values in the request header part which is wrong. The values are sent in the request body and not in the request header. Also your syntax is wrong. Correct syntax is: {"user":"user_val","password":"password_val"}. Also check what is the the content type. It should match with the content type you have set to your service.

I came here looking for a simple way to add existing source files to a GitHub repository. I saw @Pete's excellently complete answer and thought "What?! There must be a simpler way."

Here's that simpler way in five steps (no console action required!)

If you're really in a hurry, you can just read step 3. The others are only there for completeness.

1. Create a repository on the GitHub website. (I won't insult your intelligence by taking you through this step-by-step.)
2. Clone the new repository locally. (You can do this either through the website or through desktop client software.)
3. Find the newly cloned repository on your hard drive and add files just like you would to a normal directory.
4. Sync the changes back up to GitHub.
5. That's it!

Done!

Here is a rough explanation of the concepts.

[ACK] is the acknowledgement that the previously sent data packet was received.

[FIN] is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN).

So, suppose

• host A sends a data packet to host B
• and then host B wants to close the connection.
• Host B (depending on timing) can respond with [FIN,ACK] indicating that it received the sent packet and wants to close the session.
• Host A should then respond with a [FIN,ACK] indicating that it received the termination request (the ACK part) and that it too will close the connection (the FIN part).

However, if host A wants to close the session after sending the packet, it would only send a [FIN] packet (nothing to acknowledge) but host B would respond with [FIN,ACK] (acknowledges the request and responds with FIN).

Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST] instead of the usual [FIN,ACK]. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.

You can find a more detailed and comprehensive explanation here.

Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:

class Test {
  Dictionary<int,String> entities;

  public String getEntity(int code) {
    return this.entities[code];
  }
}

If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).

The following is an excerpt from my personal blog .

Using Git with 3D Games

Update Oct 2015: GitHub has since released a plugin for Git called Git LFS that directly deals with the below problem. You can now easily and efficiently version large binary files!

Git can work fine with 3D games out of the box. However the main caveat here is that versioning large (>5 MB) media files can be a problem over the long term as your commit history bloats. We have solved this potential issue in our projects by only versioning the binary asset when it is considered final. Our 3D artists use Dropbox to work on WIP assets, both for the reason above and because it's much faster and simpler (not many artists will actively want to use Git!).

Git Workflow

Your Git workflow is very much something you need to decide for yourself given your own experiences as a team and how you work together. However. I would strongly recommend the appropriately named Git Flow methodology as described by the original author here.

I won't go into too much depth here on how the methodology works as the author describes it perfectly and in quite few words too so it's easy to get through. I have been using with my team for awhile now, and it's the best workflow we've tried so far.

Git GUI Client Application

This is really a personal preference here as there are quite a few options in terms of Git GUI or whether to use a GUI at all. But I would like to suggest the free SourceTree application as it plugs in perfectly with the Git Flow extension. Read the SourceTree tutorial here on implementing the Git Flow methodology in their application.

Unity3D Settings

For versions of Unity 3D v4.3 and up:

1. (Skip this step in v4.5 and up) Enable External option in Unity ? Preferences ? Packages ? Repository.
2. Open the Edit menu and pick Project Settings ? Editor:
   1. Switch Version Control Mode to Visible Meta Files.
   2. Switch Asset Serialization Mode to Force Text.
3. Save the scene and project from File menu.

Want you migrate your existing repo to LFS?

Check out my blog post for steps on how to do it here.

Additional Configuration

One of the few major annoyances one has with using Git with Unity3D projects is that Git doesn't care about directories and will happily leave empty directories around after removing files from them. Unity3D will make *.meta files for these directories and can cause a bit of a battle between team members when Git commits keep adding and removing these meta files.

Add this Git post-merge hook to the /.git/hooks/ folder for repositories with Unity3D projects in them. After any Git pull/merge, it will look at what files have been removed, check if the directory it existed in is empty, and if so delete it.

I prefer the one line python or perl command, both often included in major linux disdribution

echo $'
<a href="http://stackoverflow.com">
</a>
<a href="http://google.com">
</a>
' |  python -c $'
import re
import sys
for i in sys.stdin:
  g=re.match(r\'.*href="(.*)"\',i);
  if g is not None:
    print g.group(1)
'

and to handle files:

ls *.txt | python -c $'
import sys
import re
for i in sys.stdin:
  i=i.strip()
  f=open(i,"r")
  for j in f:
    g=re.match(r\'.*href="(.*)"\',j);
    if g is not None:
      print g.group(1)
  f.close()
'

There is: Path.ChangeExtension method. E.g.:

var result = Path.ChangeExtension(myffile, ".jpg");

In the case if you also want to physically change the extension, you could use File.Move method:

File.Move(myffile, Path.ChangeExtension(myffile, ".jpg"));

You can fix the issue by deleting the __MigrationHistory table which is created automatically in the database and logs any update in the database using code-first migrations. Here, in this case, you manually changed your database while EF assumed you had to do it with the migration tool. Deleting the table means to the EF that there are no updates and no need to do code-first migrations thus it works perfectly fine.

Another understated reason for not using a singleton DbContext, even in a single threaded single user application, is because of the identity map pattern it uses. It means that every time you retrieve data using query or by id, it will keep the retrieved entity instances in cache. The next time you retrieve the same entity, it will give you the cached instance of the entity, if available, with any modifications you have done in the same session. This is necessary so the SaveChanges method does not end up with multiple different entity instances of the same database record(s); otherwise, the context would have to somehow merge the data from all those entity instances.

The reason that is a problem is a singleton DbContext can become a time bomb that could eventually cache the whole database + the overhead of .NET objects in memory.

There are ways around this behavior by only using Linq queries with the .NoTracking() extension method. Also these days PCs have a lot of RAM. But usually that is not the desired behavior.

Have your tried json-io (https://github.com/jdereg/json-io)?

This library allows you to serialize / deserialize any Java object graph, including object graphs with cycles in them (e.g., A->B, B->A). It does not require your classes to implement any particular interface or inherit from any particular Java class.

In addition to serialization of Java to JSON (and JSON to Java), you can use it to format (pretty print) JSON:

String niceFormattedJson = JsonWriter.formatJson(jsonString)

I want to add several observations, based on the comments that have accumulated.

1. Thread.stop() will stop a thread if the security manager allows it.
2. Thread.stop() is dangerous. Having said that, if you are working in a JEE environment and you have no control over the code being called, it may be necessary; see Why is Thread.stop deprecated?
3. You should never stop stop a container worker thread. If you want to run code that tends to hang, (carefully) start a new daemon thread and monitor it, killing if necessary.
4. stop() creates a new ThreadDeathError error on the calling thread and then throws that error on the target thread. Therefore, the stack trace is generally worthless.
5. In JRE 6, stop() checks with the security manager and then calls stop1() that calls stop0(). stop0() is native code.
6. As of Java 13 Thread.stop() has not been removed (yet), but Thread.stop(Throwable) was removed in Java 11. (mailing list, JDK-8204243)

mysql_query function is used for executing mysql query in php. mysql_query returns false if query execution fails.Alternatively you can try using mysql_error() function For e.g

$result=mysql_query($sql)

or

die(mysql_error());

In above code snippet if query execution fails then it will terminate the execution and display mysql error while execution of sql query.

If I am correct, the second parameter of substr() should be the length of the substring. How about

b = a.substr(i,2);

?

Yes include the first file into the second. That's all.

See an example below,

File1.php :

<?php
  function first($int, $string){ //function parameters, two variables.
    return $string;  //returns the second argument passed into the function
  }
?>

Now Using include (http://php.net/include) to include the File1.php to make its content available for use in the second file:

File2.php :

<?php
  include 'File1.php';
  echo first(1,"omg lol"); //returns omg lol;
?>

Trying to solve this problem myself, I discovered that there is no HeadBucket permission. It looks like there is, because that's what the error message tells you, but actually the HEAD operation requires the ListBucket permission. I also discovered that my IAM policy and my bucket policy were conflicting. Make sure you check both.

Check the version of the excel, if you are using older version then Value2 is not available for you and thus it is showing an error, while it will work with 2007+ version. Or the other way, the object is not getting created and thus the Value2 property is not available for the object.

Use apply().

It writes the changes to the RAM immediately and waits and writes it to the internal storage(the actual preference file) after. Commit writes the changes synchronously and directly to the file.

If you're on Windows, try findstr. Third-party tools are not needed:

findstr /V /L "searchstring" inputfile.txt > outputfile.txt

It supports regex's too! Just read the tool's help findstr /?.

P.S. If you want to work with big, huge files (like 400 MB log files) a text editor is not very memory-efficient, so, as someone already pointed out, command-line tools are the way to go. But there's no grep on Windows, so...

I just ran this on a 1 GB log file, and it literally took 3 seconds.

this fails:

 SET @nPortalUID = CAST(@vPortalUID AS uniqueidentifier)
 PRINT @nPortalUID

this works

the difference is NVARCHAR(36), your input parameter is too small!

Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards.

Although, this is indicated as an error your logs will be saved normally. The highlighted error will still be present until there is a fix of this bug. More about this in the m2e support site.

The current available solution is to use an external maven version rather than the bundled version of Eclipse. You can find about this solution and more details regarding this bug in the question below which i believe describes the same problem you are facing.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error

Not suitable for 2008 when the question was asked, but these days this works well for me:

async function newImageSrc(src) {
  // Get a reference to the image in whatever way suits.
  let image = document.getElementById('image-id');

  // Update the source.
  img.src = src;

  // Wait for it to load.
  await new Promise((resolve) => { image.onload = resolve; });

  // Done!
  console.log('image loaded! do something...');
}

string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

datetime is a module which contains a type that is also called datetime. You appear to want to use both, but you're trying to use the same name to refer to both. The type and the module are two different things and you can't refer to both of them with the name datetime in your program.

If you need to use anything from the module besides the datetime type (as you apparently do), then you need to import the module with import datetime. You can then refer to the "date" type as datetime.date and the datetime type as datetime.datetime.

You could also do this:

from datetime import datetime, date
today_date = date.today()
date_time = datetime.strp(date_time_string, '%Y-%m-%d %H:%M')

Here you import only the names you need (the datetime and date types) and import them directly so you don't need to refer to the module itself at all.

Ultimately you have to decide what names from the module you need to use, and how best to use them. If you are only using one or two things from the module (e.g., just the date and datetime types), it may be okay to import those names directly. If you're using many things, it's probably better to import the module and access the things inside it using dot syntax, to avoid cluttering your global namespace with date-specific names.

Note also that, if you do import the module name itself, you can shorten the name to ease typing:

import datetime as dt
today_date = dt.date.today()
date_time = dt.datetime.strp(date_time_string, '%Y-%m-%d %H:%M')

I had the same problem and the only solution that worked was:

Response.Clear();
Response.ContentType = "Application/msword";
Response.AddHeader("Content-Disposition", "attachment; filename=myfile.docx");
Response.BinaryWrite(myMemoryStream.ToArray());
// myMemoryStream.WriteTo(Response.OutputStream); //works too
Response.Flush();
Response.Close();
Response.End();

Both lines are in fact correct but do subtly different things.

The first line creates a new object on the stack by calling a constructor of the format Thing(const char*).

The second one is a bit more complex. It essentially does the following

1. Create an object of type Thing using the constructor Thing(const char*)
2. Create an object of type Thing using the constructor Thing(const Thing&)
3. Call ~Thing() on the object created in step #1

function GetCookieValue(name) {
    var found = document.cookie.split(';').filter(c => c.trim().split("=")[0] === name);
    return found.length > 0 ? found[0].split("=")[1] : null;
}

Simply put these codes at top of your PHP/index file:

error_reporting(E_ALL); // Error/Exception engine, always use E_ALL

ini_set('ignore_repeated_errors', TRUE); // always use TRUE

ini_set('display_errors', FALSE); // Error/Exception display, use FALSE only in production environment or real server. Use TRUE in development environment

ini_set('log_errors', TRUE); // Error/Exception file logging engine.
ini_set('error_log', 'your/path/to/errors.log'); // Logging file path

try this: (you missed the single quotes)

var floorplanSettings = '@Html.Raw(Json.Encode(Model.FloorPlanSettings))';

No need to use regex .... Just use list slicing ...

string="(tidtkdgkxkxlgxlhxl) ¥£%#_¥#_¥#_¥#"
print(string[string.find("(")+1:string.find(")")])

You need to attach a click event handler and clear the contents of the textarea from that handler.

HTML

<input type="button" value="Clear" id="clear"> 
<textarea id='output' rows=20 cols=90></textarea>

JS

var input = document.querySelector('#clear');
var textarea = document.querySelector('#output');

input.addEventListener('click', function () {
    textarea.value = '';
}, false);

and here's the working demo.

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f3" action="#" >
                <input id="edit3" type="submit" name="edit" value="Edit">
               </form>

   </tbody>
</table>

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "file/to/transfer";

    Session session = null;

You can generate a random number with the rand method. The argument passed to the rand method should be an integer or a range, and returns a corresponding random number within the range:

rand(9)       # this generates a number between 0 to 8
rand(0 .. 9)  # this generates a number between 0 to 9
rand(1 .. 50) # this generates a number between 1 to 50
#rand(m .. n) # m is the start of the number range, n is the end of number range

Try this,

public static Double[][] multiplicar(Double A[][],Double B[][]){
    Double[][] C= new Double[2][2];
    int i,j,k;
     for (i = 0; i < 2; i++) {
         for (j = 0; j < 2; j++) {
             C[i][j] = 0.00000;
         }
     }
    for(i=0;i<2;i++){
        for(j=0;j<2;j++){
            for (k=0;k<2;k++){
                  C[i][j]+=(A[i][k]*B[k][j]);

            }

        }
    }
    return C;
}

You can use variable by using keyword "use ($category_id)"

$category_id = array('223','15');
Products::whereIn('id', function($query) use ($category_id){
   $query->select('paper_type_id')
     ->from(with(new ProductCategory)->getTable())
     ->whereIn('category_id', $category_id )
     ->where('active', 1);
})->get();

Well, you can always use window.crypto object available in the recent version of browser.

Just need one line of code to get a random number:

let n = window.crypto.getRandomValues(new Uint32Array(1))[0];

It also helps to encrypt and decrypt data. More information at MDN Web docs - window.crypto.

To draw a centered text:

TextRenderer.DrawText(g, "my text", Font, Bounds, ForeColor, BackColor, 
  TextFormatFlags.HorizontalCenter | 
  TextFormatFlags.VerticalCenter |
  TextFormatFlags.GlyphOverhangPadding);

Determining optimal font size to fill an area is a bit more difficult. One working soultion I found is trial-and-error: start with a big font, then repeatedly measure the string and shrink the font until it fits.

Font FindBestFitFont(Graphics g, String text, Font font, 
  Size proposedSize, TextFormatFlags flags)
{ 
  // Compute actual size, shrink if needed
  while (true)
  {
    Size size = TextRenderer.MeasureText(g, text, font, proposedSize, flags);

    // It fits, back out
    if ( size.Height <= proposedSize.Height && 
         size.Width <= proposedSize.Width) { return font; }

    // Try a smaller font (90% of old size)
    Font oldFont = font;
    font = new Font(font.FontFamily, (float)(font.Size * .9)); 
    oldFont.Dispose();
  }
}

You'd use this as:

Font bestFitFont = FindBestFitFont(g, text, someBigFont, sizeToFitIn, flags);
// Then do your drawing using the bestFitFont
// Don't forget to dispose the font (if/when needed)

You can get a list of column names by running:

SELECT name FROM PRAGMA_TABLE_INFO('your_table');
name      
tbl_name  
rootpage  
sql

You can check if a certain column exists by running:

SELECT 1 FROM PRAGMA_TABLE_INFO('your_table') WHERE name='sql';
1

I agree with dfsq if all you want to do is show the button. If you want to switch between hiding and showing the button however, it is easier to use:

$("#buttonEditComment").toggleClass("hide");

you can even write it just like this:

<a href="javascript:void(0);"></a>

im not sure its a better way but it is a way :)

b = a(find(a~=0))

I think you face three problems:

1. understanding the FileChooser
2. writing/reading files
3. understanding extensions and file formats

ad 1. Are you sure you've connected the FileChooser to a correct panel/container? I'd go for a simple tutorial on this matter and see if it works. That's the best way to learn - by making small but large enough steps forward. Breaking down an issue into such parts might be tricky sometimes ;)

ad. 2. After you save or open the file you should have methods to write or read the file. And again there are pretty neat examples on this matter and it's easy to understand topic.

ad. 3. There's a difference between a file having extension and file format. You can change the format of any file to anything you want but that doesn't affect it's contents. It might just render the file unreadable for the application associated with such extension. TXT files are easy - you read what you write. XLS, DOCX etc. require more work and usually framework is the best way to tackle these.

I strip before and after data.

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;
 using System.Text.RegularExpressions;

 namespace testApp
 {
     class Program
     {
         static void Main(string[] args)
         {
             string tempString = "morenonxmldata<tag1>0002</tag1>morenonxmldata";
             tempString = Regex.Replace(tempString, "[\\s\\S]*<tag1>", "");//removes all leading data
             tempString = Regex.Replace(tempString, "</tag1>[\\s\\S]*", "");//removes all trailing data

             Console.WriteLine(tempString);
             Console.ReadLine();
         }
     }
 }

There seems a different consensus in the C# and Java camps on this. The majority of Java code I have seen uses:

// apply mutex to this instance
synchronized(this) {
    // do work here
}

whereas the majority of C# code opts for the arguably safer:

// instance level lock object
private readonly object _syncObj = new object();

...

// apply mutex to private instance level field (a System.Object usually)
lock(_syncObj)
{
    // do work here
}

The C# idiom is certainly safer. As mentioned previously, no malicious / accidental access to the lock can be made from outside the instance. Java code has this risk too, but it seems that the Java community has gravitated over time to the slightly less safe, but slightly more terse version.

That's not meant as a dig against Java, just a reflection of my experience working on both languages.

PSH> $cred = Get-Credential

PSH> $cred | Export-CliXml c:\temp\cred.clixml

PSH> $cred2 = Import-CliXml c:\temp\cred.clixml

That hashes it against your SID and the machine's SID, so the file is useless on any other machine, or in anyone else's hands.

Yes you can. The default location for script files is data/db

If you put any script there you can call it as

load("myjstest.js")      // or 
load("/data/db/myjstest.js")

As of rails 5 you can also use rails instead of rake

Rails 3 - 4

# < rails-5.0
rake db:migrate:up VERSION=20160920130051

Rails 5

# >= rails-5.0
rake db:migrate:up VERSION=20160920130051

# or

rails db:migrate:up VERSION=20160920130051

the alphanum function (self answered) have a bug, but I don't know why. For text "cas synt ls 75W140 1L" return "cassyntls75W1401", "L" from the end is missing some how.

Now I use

delimiter //

  DECLARE i INT DEFAULT 1;
  DECLARE v_char VARCHAR(1);

WHILE (i <= LENGTH(prm_strInput) )  DO
  SET v_char = SUBSTR(prm_strInput,i,1);
  IF v_char REGEXP  '^[A-Za-z0-9]+$' THEN 
        SET v_parseStr = CONCAT(v_parseStr,v_char);  
  END IF;
  SET i = i + 1;
END WHILE;
RETURN trim(v_parseStr);

If you specifically want to use an ad hoc wireless network, then Andy's answer seems to be your only option. However, if you just want to share your laptop's internet connection via Wi-fi using any means necessary, then you have at least two more options:

1. Use your laptop as a router to create a wifi hotspot using Virtual Router or Connectify. A nice set of instructions can be found here.
2. Use the Wi-fi Direct protocol which creates a direct connection between any devices that support it, although with Android devices support is limited* and with Windows the feature seems likely to be Windows 8 only.

*Some phones with Android 2.3 have proprietary OS extensions that enable Wi-fi Direct (mostly newer Samsung phones), but Android 4 should fully support this (source).

if you get "unexpected Character" error you should check if there is a BOM (Byte Order Marker saved into your utf-8 json. You can either remove the first character or save if without BOM.

try them if it help.

As the question is answered. For web develoment. I came so far and found a good explanation about bootsrapping in Laravel doc. Here is the link

In general, we mean registering things, including registering service container bindings, event listeners, middleware, and even routes.

hope it will help someone who learning web application development.

Well, the problem you have is wrong line ending/encoding for notepad. Notepad uses Windows' line endings - \r\n and you use \n.

; Default Value: On
; Development Value: Off

Looks file you use the .mkdirs() method on a File object: http://www.roseindia.net/java/beginners/java-create-directory.shtml

// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
    // Directory creation failed
}

You have to set "secondary okay" mode to let the mongo shell know that you're allowing reads from a secondary. This is to protect you and your applications from performing eventually consistent reads by accident. You can do this in the shell with:

rs.secondaryOk()

After that you can query normally from secondaries.

A note about "eventual consistency": under normal circumstances, replica set secondaries have all the same data as primaries within a second or less. Under very high load, data that you've written to the primary may take a while to replicate to the secondaries. This is known as "replica lag", and reading from a lagging secondary is known as an "eventually consistent" read, because, while the newly written data will show up at some point (barring network failures, etc), it may not be immediately available.

Edit: You only need to set secondaryOk when querying from secondaries, and only once per session.

This is what worked for me

find . -type f -name "*.svg" -exec bash -c 'rsvg-convert -h 1000  $0 > $0.png' {} \;
rename 's/svg\.png/png/' *

This will loop all the files in your current folder and sub folder and look for .svg files and will convert it to png with transparent background.

Make sure you have installed the librsvg and rename util

brew install librsvg
brew install rename

I have searched and searched and played and played with it and although it is not perfect it may help others making the attempt to validate first and last names that have been provided as one variable.

In my case, that variable is $name.

I used the following code for my PHP:

    if (preg_match('/\b([A-Z]{1}[a-z]{1,30}[- ]{0,1}|[A-Z]{1}[- \']{1}[A-Z]{0,1}  
    [a-z]{1,30}[- ]{0,1}|[a-z]{1,2}[ -\']{1}[A-Z]{1}[a-z]{1,30}){2,5}/', $name)  
    # there is no space line break between in the above "if statement", any that   
    # you notice or perceive are only there for formatting purposes.  
    # 
    # pass - successful match - do something
    } else {
    # fail - unsuccessful match - do something

I am learning RegEx myself but I do have the explanation for the code as provided by RegEx buddy.
Here it is:

Assert position at a word boundary «\b»

Match the regular expression below and capture its match into backreference number 1
«([A-Z]{1}[a-z]{1,30}[- ]{0,1}|[A-Z]{1}[- \']{1}[A-Z]{0,1}[a-z]{1,30}[- ]{0,1}|[a-z]{1,2}[ -\']{1}[A-Z]{1}[a-z]{1,30}){2,5}»

Between 2 and 5 times, as many times as possible, giving back as needed (greedy) «{2,5}»

* I NEED SOME HELP HERE WITH UNDERSTANDING THE RAMIFICATIONS OF THIS NOTE *

Note: I repeated the capturing group itself. The group will capture only the last iteration. Put a capturing group around the repeated group to capture all iterations. «{2,5}»

Match either the regular expression below (attempting the next alternative only if this one fails) «[A-Z]{1}[a-z]{1,30}[- ]{0,1}»

Match a single character in the range between “A” and “Z” «[A-Z]{1}»

Exactly 1 times «{1}»

Match a single character in the range between “a” and “z” «[a-z]{1,30}»

Between one and 30 times, as many times as possible, giving back as needed (greedy) «{1,30}»

Match a single character present in the list “- ” «[- ]{0,1}»

Between zero and one times, as many times as possible, giving back as needed (greedy) «{0,1}»

Or match regular expression number 2 below (attempting the next alternative only if this one fails) «[A-Z]{1}[- \']{1}[A-Z]{0,1}[a-z]{1,30}[- ]{0,1}»

Match a single character in the range between “A” and “Z” «[A-Z]{1}»

Exactly 1 times «{1}»

Match a single character present in the list below «[- \']{1}»

Exactly 1 times «{1}»

One of the characters “- ” «- » A ' character «\'»

Match a single character in the range between “A” and “Z” «[A-Z]{0,1}»

Between zero and one times, as many times as possible, giving back as needed (greedy) «{0,1}»

Match a single character in the range between “a” and “z” «[a-z]{1,30}»

Between one and 30 times, as many times as possible, giving back as needed (greedy) «{1,30}»

Match a single character present in the list “- ” «[- ]{0,1}»

Between zero and one times, as many times as possible, giving back as needed (greedy) «{0,1}»

Or match regular expression number 3 below (the entire group fails if this one fails to match) «[a-z]{1,2}[ -\']{1}[A-Z]{1}[a-z]{1,30}»

Match a single character in the range between “a” and “z” «[a-z]{1,2}»

Between one and 2 times, as many times as possible, giving back as needed (greedy) «{1,2}»

Match a single character in the range between “ ” and “'” «[ -\']{1}»

Exactly 1 times «{1}»

Match a single character in the range between “A” and “Z” «[A-Z]{1}»

Exactly 1 times «{1}»

Match a single character in the range between “a” and “z” «[a-z]{1,30}»

Between one and 30 times, as many times as possible, giving back as needed (greedy) «{1,30}»

I know this validation totally assumes that every person filling out the form has a western name and that may eliminates the vast majority of folks in the world. However, I feel like this is a step in the proper direction. Perhaps this regular expression is too basic for the gurus to address simplistically or maybe there is some other reason that I was unable to find the above code in my searches. I spent way too long trying to figure this bit out, you will probably notice just how foggy my mind is on all this if you look at my test names below.

I tested the code on the following names and the results are in parentheses to the right of each name.

1. STEVE SMITH (fail)
2. Stev3 Smith (fail)
3. STeve Smith (fail)
4. Steve SMith (fail)
5. Steve Sm1th (passed on the Steve Sm)
6. d'Are to Beaware (passed on the Are to Beaware)
7. Jo Blow (passed)
8. Hyoung Kyoung Wu (passed)
9. Mike O'Neal (passed)
10. Steve Johnson-Smith (passed)
11. Jozef-Schmozev Hiemdel (passed)
12. O Henry Smith (passed)
13. Mathais d'Arras (passed)
14. Martin Luther King Jr (passed)
15. Downtown-James Brown (passed)
16. Darren McCarty (passed)
17. George De FunkMaster (passed)
18. Kurtis B-Ball Basketball (passed)
19. Ahmad el Jeffe (passed)

If you have basic names, there must be more than one up to five for the above code to work, that are similar to those that I used during testing, this code might be for you.

If you have any improvements, please let me know. I am just in the early stages (first few months of figuring out RegEx.

Thanks and good luck, Steve

In my case (I'm using Carthage) the problem with

error: Multiple commands produce 
1) Target *** has copy command from
2) That command depends on command in Target ***: script phase “Run Carthage Script” 

was caused due to importing frameworks both to Embeded frameworks and Run carthage script phases in Build Phases configuration

These 2 phases copy frameworks to derrived data, so Xcode see duplicated files and print these errors with warning:

ignoring duplicated output file: (in target ***)

After removing duplicated frameworks from Embeded frameworks phase everything is working correctly.

Your DOS command 2> nul

Read page Using command redirection operators. Besides the "2>" construct mentioned by Tanuki Software, it lists some other useful combinations.

I will say before all that this will not always works, i have tested this with sans-serif font and external fonts like open sans

Sometimes, when you use huge fonts, try to approximate to font-size:49px and upper

This is a header text with a size of 48px (font-size:48px; in the element that contains the text).

But, if you up the 48px to font-size:49px; (and 50px, 60px, 80px, etc...), something interesting happens

The text automatically get smooth, and seems really good

For another side...

If you are looking for small fonts, you can try this, but isn't very effective.

To the parent of the text, just apply the next css property: -webkit-backface-visibility: hidden;

You can transform something like this:

To this:

(the font is Kreon)

Consider that when you are not putting that property, -webkit-backface-visibility: visible; is inherit

But be careful, that practice will not give always good results, if you see carefully, Chrome just make the text look a little bit blurry.

Another interesting fact:

-webkit-backface-visibility: hidden; will works too when you transform a text in Chrome (with the -webkit-transform property, that includes rotations, skews, etc)

Without -webkit-backface-visibility: hidden;

With -webkit-backface-visibility: hidden;

Well, I don't know why that practices works, but it does for me. Sorry for my weird english.

The plus sign is the historic encoding for a space character in URL parameters, as documented in the help for the urlencode() function.

That same page contains the answer you need - use rawurlencode() instead to get RFC 3986 compatible encoding.

I had this same problem and stumbled upon the following simple solution. Just add a bit of padding to the image and it resizes itself to fit within the div.

<div class="col-sm-3">
  <img src="xxx.png" class="img-responsive" style="padding-top: 5px">
</div>

It should normally be done with Request.Form["elementName"].

For example, if you have <input type="text" name="email" /> then you can use Request.Form["email"] to access its value.

Well in JavaScript you can check two strings for values same as integers so yo can do this:

• "A" < "B"
• "A" == "B"
• "A" > "B"

And therefore you can make your own function that checks strings the same way as the strcmp().

So this would be the function that does the same:

function strcmp(a, b)
{   
    return (a<b?-1:(a>b?1:0));  
}

Since there is no issue with GC. I prefer this.

for(int i=0; i<array.length; ++i){
    if(array[i] == valueToFind)
        return true;
}

The EF Core doesn't create DBset for the SQL views automatically in the context calss, we can add them manually as below.

public partial class LocalDBContext : DbContext
{ 

    public LocalDBContext(DbContextOptions<LocalDBContext> options) : base(options)
    {

    }

    public virtual DbSet<YourView> YourView { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<YourView>(entity => {
            entity.HasKey(e => e.ID);
            entity.ToTable("YourView");
            entity.Property(e => e.Name).HasMaxLength(50);
        });
    }

}

The sample view is defined as below with few properties

using System;
using System.Collections.Generic;

namespace Project.Entities
{
    public partial class YourView
    {
        public string Name { get; set; }
        public int ID { get; set; }
    }
}

After adding a class for the view and DB set in the context class, you are good to use the view object through your context object in the controller.

I had the same problem.I solved with following command maven:

mvn eclipse:eclipse -Dwtpversion=2.0

PS: My project is WTP plugin

Try this (apply to a class you image is in (not img itself), e.g.

.myimage {
  background: transparent url("yourimage.png") no-repeat top center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: 100%;
  height: 500px;
}

The best way to get the id of the entity you added is like this:

public int InsertEntity(Entity factor)
{
    Db.Entities.Add(factor);
    Db.SaveChanges();
    var id = factor.id;
    return id;
}

Install Tidy2 plugin. I have Notepad++ v6.2.2, and Tidy2 works fine so far.

My approach was as below. Now I just wanted my form to be validated when one specific checkbox was clicked/changed:

$('#myForm input:checkbox[name=yourChkBxName]').click(
 function(e){
  $("#myForm").valid();
}
)

If you wish to use CV2, you need to use the resize function.

For example, this will resize both axes by half:

small = cv2.resize(image, (0,0), fx=0.5, fy=0.5) 

and this will resize the image to have 100 cols (width) and 50 rows (height):

resized_image = cv2.resize(image, (100, 50)) 

Another option is to use scipy module, by using:

small = scipy.misc.imresize(image, 0.5)

There are obviously more options you can read in the documentation of those functions (cv2.resize, scipy.misc.imresize).

Update:
According to the SciPy documentation:

imresize is deprecated in SciPy 1.0.0, and will be removed in 1.2.0.
Use skimage.transform.resize instead.

Note that if you're looking to resize by a factor, you may actually want skimage.transform.rescale.

To get the iframe to always load fresh content, add the current Unix timestamp to the end of the GET parameters. The browser then sees it as a 'different' request and will seek new content.

In Javascript, it might look like:

frames['my_iframe'].location.href='load_iframe_content.php?group_ID=' + group_ID + '&timestamp=' + timestamp;

create dir platforms and copy qwindows.dll to it, platforms and app.exe are in the same dir

cd app_dir mkdir platforms xcopy qwindows.dll platforms\qwindows.dll

Folder structure + app.exe + platforms\qwindows.dll

try:

var url = '/Home/Index/' + e.value;
 window.location = window.location.host + url; 

That should get you where you want.

This can help too

td[style] {height: 50px !important;}

This will override any inline style

But, sometimes, even with user-select and touch-callout turned off, cursor: pointer; may cause this effect, so, just set cursor: default; and it'll work.

Call

Calls one batch program from another without stopping the parent batch program. The call command accepts labels as the target of the call. Call has no effect at the command-line when used outside of a script or batch file. https://technet.microsoft.com/en-us/library/bb490873.aspx

Start

Starts a separate Command Prompt window to run a specified program or command. Used without parameters, start opens a second command prompt window. https://technet.microsoft.com/en-us/library/bb491005.aspx

The listed answers won't work if the results of the AJAX form submit affects the HTML outside the scope of the modal before the modal finishes closing. In my case, the result was a grayed out (fade) screen where I could see the page update, but could not interact with any of the page elements.

My solution:

$(document).on("click", "#send-email-submit-button", function(e){
    $('#send-new-email-modal').modal('hide')
});

 $(document).on("submit", "#send-email-form", function(e){
    e.preventDefault();
    var querystring = $(this).serialize();
    $.ajax({
        type: "POST",
        url: "sendEmailMessage",
        data : querystring,
        success : function(response) {
            $('#send-new-email-modal').on('hidden.bs.modal', function () {
                $('#contacts-render-target').html(response);
            }
    });
    return false;
});

Note: My modal form was inside a parent div that was already rendered via AJAX, thus the need to anchor the event listener to document.

Using -engine specific rules ensures effective browser targeting.

Add this in your input element

<input
    action="action"
    onclick="window.history.go(-1); return false;"
    type="submit"
    value="Cancel"
/>

You can use string.match() and a regular expression for this too:

if(pathname.match(/^\/sub\/1/)) { // you need to escape the slashes

string.match() will return an array of matching substrings if found, otherwise null.

Here's an example where I change the background image from one to another with a 2 second alpha fade delay both ways - 2s fadeout of the original image into a 2s fadein into the 2nd image.

    public void fadeImageFunction(View view) {

    backgroundImage = (ImageView) findViewById(R.id.imageViewBackground);
    backgroundImage.animate().alpha(0f).setDuration(2000);

    // A new thread with a 2-second delay before changing the background image
    new Timer().schedule(
            new TimerTask(){
                @Override
                public void run(){
                    // you cannot touch the UI from another thread. This thread now calls a function on the main thread
                    changeBackgroundImage();
                }
            }, 2000);
   }

// this function runs on the main ui thread
private void changeBackgroundImage(){
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            backgroundImage = (ImageView) findViewById(R.id.imageViewBackground);
            backgroundImage.setImageResource(R.drawable.supes);
            backgroundImage.animate().alpha(1f).setDuration(2000);
        }
    });
}

For anyone who may stumble across this thread while trying to fix this same error that results by running Enable-Migrations, chances are none of the solutions above will help you (I tried them all).

I encountered this same issue in Web API 2 after running this in PM console:

Enable-Migrations -EnableAutomaticMigrations -ConnectionString IdentityConnection -ConnectionProviderName System.Data.SqlClient -Force

I fixed it by changing it to actually use the ApplicationDbContext created in IdentityModels.

Enable-Migrations -ContextTypeName ApplicationDbContext -EnableAutomaticMigrations -Force

The interesting thing is not only does this reference the same exact connection string, but the constructor includes code that 4castle said was a potential fix (i.e., the throwIfV1Schema: false suggestion.

Note that the -Force parameter is only being used because the Configuration.cs file already exists.

I got half way through (till null, and one node as suggested by plinth), but lost track after making recursive call. However, after reading the post by plinth, here is what I came up with:

Node reverse(Node head) {
  // if head is null or only one node, it's reverse of itself.
  if ( (head==null) || (head.next == null) ) return head;

  // reverse the sub-list leaving the head node.
  Node reverse = reverse(head.next);

  // head.next still points to the last element of reversed sub-list.
  // so move the head to end.
  head.next.next = head;

  // point last node to nil, (get rid of cycles)
  head.next = null;
  return reverse;
}

The hint (using axfr) only works if the NS you're querying (ns1.foo.bar in your example) is configured to allow AXFR requests from the IP you're using; this is unlikely, unless your IP is configured as a secondary for the domain in question.

Basically, there's no easy way to do it if you're not allowed to use axfr. This is intentional, so the only way around it would be via brute force (i.e. dig a.some_domain.com, dig b.some_domain.com, ...), which I can't recommend, as it could be viewed as a denial of service attack.

I know this is quite old, but when a lost stranger finds this question looking for an answer (like I did) then this is the best way to do it, instead of using removeAttr():

$element.prop("onclick", null);

Citing jQuerys official doku:

"Removing an inline onclick event handler using .removeAttr() doesn't achieve the desired effect in Internet Explorer 6, 7, or 8. To avoid potential problems, use .prop() instead"

My Specs:

mysql --version
mysql  Ver 8.0.16 for Linux on x86_64 (MySQL Community Server - GPL)

What worked for me:

mysql> CREATE USER 'username'@'localhost' IDENTIFIED BY 'desired_password';
mysql> GRANT ALL PRIVILEGES ON db_name.* TO 'username'@'localhost' WITH GRANT OPTION;

Response in both queries:

Query OK, O rows affected (0.10 sec*)

N.B: I created a database (db_name) earlier and was creating a user credential with all privileges granted to all tables in the DB in place of using the default root user which I read somewhere is a best practice.

Otherwise for old version, if '--show-item' is not recognize, you can use the following command :

svn log -r HEAD | grep -o -E "^r[0-9]{1,}" | sed 's/r//g'

Hope it helps.

You can access keys in the App.Config using:

This problem happens because you are calling fun.cpp instead of fun.hpp. So c++ compiler finds func.cpp definition twice and throws this error.

Change line 3 of your main.cpp file, from #include "fun.cpp" to #include "fun.hpp" .

The schema definition should be unique for a collection, it should not be more then one schema for a collection.

You can use it like this in template without any filters

{{ car.date_of_manufacture.strftime('%Y-%m-%d') }}

Assuming $WORKING_DIR is set to the directory... this one-liner should do it:

(otherwise just replace with your directory)

LPCWSTR is equivalent to wchar_t const *. It's a pointer to a wide character string that won't be modified by the function call.

You can assign to LPCWSTRs by prepending a L to a string literal: LPCWSTR *myStr = L"Hello World";

LPCTSTR and any other T types, take a string type depending on the Unicode settings for your project. If _UNICODE is defined for your project, the use of T types is the same as the wide character forms, otherwise the Ansi forms. The appropriate function will also be called this way: FindWindowEx is defined as FindWindowExA or FindWindowExW depending on this definition.

AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.

As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.

So AArch64 and ARM64 refer to the same thing.

Ask "What unit testing framework do you use? and why?"

You can decide if actually using a testing framework is really necessary, but the conversation might tell you a lot about how expert the person is.

EDIT:

Apparently, there is no reliable way to do this. See: Is there any way to specify a suggested filename when using data: URI?

The above answer is useful but in graphs, it is difficult to distinguish between darker gradients of black. One alternative I found is to use gradients of gray colors as follows

palette(gray.colors(10, 0.9, 0.4))
plot(rep(1,10),col=1:10,pch=19,cex=3))

More info on gray scale here.

When I used the code above for different colours like blue and black, the gradients were not that clear. heat.colors() seems more useful.

My experience with this was that when I had this in every execution it was fine using the provider as a string like this

Security.addProvider(new BounctCastleProvider());
new JcaPEMKeyConverter().setProvider("BC");

But when I optimized and put the following in the constructor:

   if(bounctCastleProvider == null) {
      bounctCastleProvider = new BouncyCastleProvider();
    }

    if(Security.getProvider(bouncyCastleProvider.getName()) == null) {
      Security.addProvider(bouncyCastleProvider);
    }

Then I had to use provider like this or I would get the above error:

new JcaPEMKeyConverter().setProvider(bouncyCastleProvider);

I am using bcpkix-jdk15on version 1.65

This sounds to me like what you have is one command with 2 outputs, I would opt for making the change in both client and server for this.

At the client, use JS to build up the URL you want to post to (use JQuery for simplicity) i.e.

<script type="text/javascript">
    $(function() {
        // this code detects a button click and sets an `option` attribute
        // in the form to be the `name` attribute of whichever button was clicked
        $('form input[type=submit]').click(function() {
            var $form = $('form');
            form.removeAttr('option');
            form.attr('option', $(this).attr('name'));
        });
        // this code updates the URL before the form is submitted
        $("form").submit(function(e) { 
            var option = $(this).attr("option");
            if (option) {
                e.preventDefault();
                var currentUrl = $(this).attr("action");
                $(this).attr('action', currentUrl + "/" + option).submit();     
            }
        });
    });
</script>
...
<input type="submit" ... />
<input type="submit" name="excel" ... />

Now at the server side we can add a new route to handle the excel request

routes.MapRoute(
    name: "ExcelExport",
    url: "SearchDisplay/Submit/excel",
    defaults: new
    {
        controller = "SearchDisplay",
        action = "SubmitExcel",
    });

You can setup 2 distinct actions

public ActionResult SubmitExcel(SearchCostPage model)
{
   ...
}

public ActionResult Submit(SearchCostPage model)
{
   ...
}

Or you can use the ActionName attribute as an alias

public ActionResult Submit(SearchCostPage model)
{
   ...
}

[ActionName("SubmitExcel")]
public ActionResult Submit(SearchCostPage model)
{
   ...
}

Addition to @jwize's answer

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

  function compileAngularElement( elSelector) {

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

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

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

        }

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

compileAngularElement( '.user' ) ;

If the user name that is in the connection string has access to more then one database you have to specify the database you want the connection string to connect to. If your user has only one database available then you are correct that it doesn't matter. But it is good practice to put this in your connection string.

I had docker up to date, docker said it was running, and the diagnosis was good. I needed to unset some legacy environment variable (thanks https://docs.docker.com/docker-for-mac/troubleshoot/#workarounds-for-common-problems )

unset DOCKER_HOST
unset DOCKER_CERT_PATH
unset DOCKER_TLS_VERIFY

To add some text, what I did some time ago , if the link you are sharing its a page you can modify. You can add some meta-tags to the shared page:

<meta name="title" content="The title you want" />
<meta name="description" content="The text you want to insert " />
<link rel="image_src" href="A thumbnail you can show" / >

It's a small hack. Although the old share button has been replaced by the "like"/"recommend" button where you can add a comment if you use the XFBML version. More info her:

• When will the the compiler not know when to make a function/method 'inline'?

This depends on the compiler used. Do not blindly trust that nowadays compilers know better then humans how to inline and you should never use it for performance reasons, because it's linkage directive rather than optimization hint. While I agree that ideologically are these arguments correct encountering reality might be a different thing.

After reading multiple threads around I tried out of curiosity the effects of inline on the code I'm just working and the results were that I got measurable speedup for GCC and no speed up for Intel compiler.

(More detail: math simulations with few critical functions defined outside class, GCC 4.6.3 (g++ -O3), ICC 13.1.0 (icpc -O3); adding inline to critical points caused +6% speedup with GCC code).

So if you qualify GCC 4.6 as a modern compiler the result is that inline directive still matters if you write CPU intensive tasks and know where exactly is the bottleneck.

Yes, you can get it with unpyclib that can be found on pypi.

$ pip install unpyclib

Than you can decompile your .pyc file

$ python -m unpyclib.application -Dq path/to/file.pyc

When you do a push, git only takes the changes that you have committed.

Remember when you do a git status it shows you the files you changed since the last push?

Once you commit those changes and do a push they are the only files that get pushed so you don't have to worry about thinking that the entire master gets pushed because in reality it does not.

How to push a single file:

git commit yourfile.js
git status
git push origin master

If I understand well you can only check if a listener has been checked but not which listener is presenter specifically.

So some ad hoc code would fill the gap to handle your coding flow. A practical method would be to create a state using variables. For example, attach a listener's checker as following:

var listenerPresent=false

then if you set a listener just change the value:

listenerPresent=true

then inside your eventListener 's callback you can assign specific functionalities inside and in this same way, distribute the access to functionalities depending of some state as variable for example:

accessFirstFunctionality=false
accessSecondFunctionality=true
accessThirdFunctionality=true

You should add fstream::out to open method like this:

file.open("test.txt",fstream::out);

More information about fstream flags, check out this link: http://www.cplusplus.com/reference/fstream/fstream/open/

Solution : 1.Project -> Build Path -> Configure Build Path

2.Select Java Build path on the left menu, and select "Source"

3.Under Project select Include(All) and click OK

Cause : The issue might because u might have deleted the CLASS files or dependencies on the project

This worked for me. If you got Maximum execution time 300 exceeded in DBIMysqli.class.php file. Open the following file in text editor C:\xampp\phpMyAdmin\libraries\config.default.php then search the following line of code:

$cfg[‘ExecTimeLimit’] = 300;

and change value 300 to 900.

You have several options

• Get map.values() , which gets the values, not the keys
• Get the map.entrySet() which has both
• Get the keySet() and for each key call map.get(key)

dbo is the default schema in SQL Server. You can create your own schemas to allow you to better manage your object namespace.

Check what's the CONSTRAINT name and the FOREIGN KEY name:

SHOW CREATE TABLE table_name;

Remove both the CONSTRAINT name and the FOREIGN KEY name:

ALTER TABLE table_name
  DROP FOREIGN KEY the_name_after_CONSTRAINT,
  DROP KEY the_name_after_FOREIGN_KEY;

Hope this helps!

/var/www/html is just the default root folder of the web server. You can change that to be whatever folder you want by editing your apache.conf file (usually located in /etc/apache/conf) and changing the DocumentRoot attribute (see http://httpd.apache.org/docs/current/mod/core.html#documentroot for info on that)

Many hosts don't let you change these things yourself, so your mileage may vary. Some let you change them, but only with the built in admin tools (cPanel, for example) instead of via a command line or editing the raw config files.

call/apply executes function immediately:

func.call(context, arguments);
func.apply(context, [argument1,argument2,..]);

bind doesn't execute function immediately, but returns wrapped apply function (for later execution):

function bind(func, context) {
    return function() {
        return func.apply(context, arguments);
    };
}

Here is a shorter version of the function presented above:

function getWidth() {
    if (self.innerWidth) {
       return self.innerWidth;
    }
    else if (document.documentElement && document.documentElement.clientHeight){
        return document.documentElement.clientWidth;
    }
    else if (document.body) {
        return document.body.clientWidth;
    }
    return 0;
}

Check to see if you have a Debuggable attribute in your AssemblyInfo file. If there is, remove it and rebuild your solution to see if the local variables become available.

My debuggable attribute was set to: DebuggableAttribute.DebuggingModes.IgnoreSymbolStoreSequencePoints which according to this MSDN article tells the JIT compiler to use optimizations. I removed this line from my AssemblyInfo.cs file and the local variables were available.

If your list of words is of substantial length, and you need to do this test many times, it may be worth converting the list to a set and using set intersection to test (with the added benefit that you wil get the actual words that are in both lists):

>>> long_word_list = 'some one long two phrase three about above along after against'
>>> long_word_set = set(long_word_list.split())
>>> set('word along river'.split()) & long_word_set
set(['along'])

If you specifically want to use the SQL Server PIVOT function, then this should work, assuming your two original columns are called act and cmd. (Not that pretty to look at though.)

SELECT act AS 'Action', [View] as 'View', [Edit] as 'Edit'
FROM (
    SELECT act, cmd FROM data
) AS src
PIVOT (
    MAX(cmd) FOR cmd IN ([View], [Edit])
) AS pvt

CREATE TABLE t (d1 timestamp, d2 timestamp);

INSERT INTO t VALUES ('2010-03-11 12:00:00', '2010-03-30 05:00:00');
INSERT INTO t VALUES ('2010-03-11 12:00:00', '2010-03-30 13:00:00');
INSERT INTO t VALUES ('2010-03-11 00:00:00', '2010-03-30 13:00:00');
INSERT INTO t VALUES ('2010-03-10 12:00:00', '2010-03-30 13:00:00');
INSERT INTO t VALUES ('2010-03-10 12:00:00', '2010-04-01 13:00:00');

SELECT d2, d1, DATEDIFF(d2, d1) AS diff FROM t;

It didn't work, because QuerySets are not JSON serializable.

1) In case of json.dumps you have to explicitely convert your QuerySet to JSON serializable objects:

class Model(model.Model):
    def as_dict(self):
        return {
            "id": self.id,
            # other stuff
        }

And the serialization:

dictionaries = [ obj.as_dict() for obj in self.get_queryset() ]
return HttpResponse(json.dumps({"data": dictionaries}), content_type='application/json')

2) In case of serializers. Serializers accept either JSON serializable object or QuerySet, but a dictionary containing a QuerySet is neither. Try this:

serializers.serialize("json", self.get_queryset())

Read more about it here:

https://docs.djangoproject.com/en/dev/topics/serialization/

For me this error occurred simply because I forgot tell Eclipse that I wanted a runnable jar file and not a simple library jar file. So when you create the jar file in Eclipse make sure that you click the right radio button

It's usually \t in command-line interfaces, which will convert the char \t into the whitespace tab character.

For example, hello\talex -> hello--->alex.

A simple &nbsp; between input fields would do the job easily...
