This error can also occur if your interface name is different than the file it is contained in. Read about ES6 modules for details. If the SignInComponent was an interface, as was in my case, then

SignInComponent

should be in a file named SignInComponent.ts.

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

Yes I think this would be quicker.

As of February 2020, for Android Studio 3.5.3, the simplest answer I found is this video.

Note 1: At 01.24 "Find" tab appears below. Click "Do Refactor" and continue as in the video.

Note 2: If you have any Java/Kotlin files "Marked as Plain Text" you need to modify the package name at the top manually, i.e. package com.example.thisplaceneedstobemanuallyupdated

Note 3: Be careful about letter cases while renaming, just as in the video.

Note 4: If you want to update the project name on title bar of project window, modify rootProject.name = 'YourProjectName' inside "settings.gradle" file under "Gradle Scripts" directory.

If you don't want to add LINQ or other extensions just do:

float[] subArray = new List<float>(myArray).GetRange(0, 8).ToArray();

Here is the solution :

@media (min-width: 1200px) {
    .container{
        max-width: 970px;
    }
}

The advantage of doing this, versus customizing Bootstrap as in @Bastardo's answer, is that it doesn't change the Bootstrap file. For example, if using a CDN, you can still download most of Bootstrap from the CDN.

You can also use position fixed css property.

<!-- html code --> 
<div class="box" id="myElement"></div>

/* css code */
.box {
    position: fixed;
}

// js code

document.getElementById('myElement').style.top = 0; //or whatever 
document.getElementById('myElement').style.left = 0; // or whatever

1.exports -> use as singleton utility
2. module-exports -> use as logical objects such as service , model etc

Figure out what version of python3 you have installed:

yum search pip

and then install the best match. Use reqoquery to find name of resulting pip3.e.g

repoquery -l python36u-pip

tells me to use pip3.6 instead of pip3

Based on @jared-burrows' solution. For any package, but passing Context as parameter...

public static String getDataDir(Context context) throws Exception {
    return context.getPackageManager()
            .getPackageInfo(context.getPackageName(), 0)
            .applicationInfo.dataDir;
}

Since nobody has mentioned this..

If all you want is an array of values, an easier alternative would be to use the .map() method. Just remember to call .get() to convert the jQuery object to an array:

Example Here

var names = $('.parent input:checked').map(function () {
    return this.name;
}).get();

console.log(names);

var names = $('.parent input:checked').map(function () {_x000D_
    return this.name;_x000D_
}).get();_x000D_
_x000D_
console.log(names);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div class="parent">_x000D_
    <input type="checkbox" name="name1" />_x000D_
    <input type="checkbox" name="name2" />_x000D_
    <input type="checkbox" name="name3" checked="checked" />_x000D_
    <input type="checkbox" name="name4" checked="checked" />_x000D_
    <input type="checkbox" name="name5" />_x000D_
</div>

Pure JavaScript:

Example Here

var elements = document.querySelectorAll('.parent input:checked');
var names = Array.prototype.map.call(elements, function(el, i) {
    return el.name;
});

console.log(names);

var elements = document.querySelectorAll('.parent input:checked');_x000D_
var names = Array.prototype.map.call(elements, function(el, i){_x000D_
    return el.name;_x000D_
});_x000D_
_x000D_
console.log(names);

<div class="parent">_x000D_
    <input type="checkbox" name="name1" />_x000D_
    <input type="checkbox" name="name2" />_x000D_
    <input type="checkbox" name="name3" checked="checked" />_x000D_
    <input type="checkbox" name="name4" checked="checked" />_x000D_
    <input type="checkbox" name="name5" />_x000D_
</div>

Here's how I did it in Excel 2003 using conditional formatting.

To apply conditional formatting to Sheet1 using values from Sheet2, you need to mirror the values into Sheet1.

Creating a mirror of Sheet2, column B in Sheet 1

1. Go to Sheet1.
2. Insert a new column by right-clicking column A's header and selecting "Insert".

3. Enter the following formula into A1:

   =IF(ISBLANK(Sheet2!B1),"",Sheet2!B1)

4. Copy A1 by right-clicking it and selecting "Copy".
5. Paste the formula into column A by right-clicking its header and selecting "Paste".

Sheet1, column A should now exactly mirror the values in Sheet2, column B.

(Note: if you don't like it in column A, it works just as well to have it in column Z or anywhere else.)

Applying the conditional formatting

1. Stay on Sheet1.
2. Select column B by left-clicking its header.
3. Select the menu item Format > Conditional Formatting...

4. Change Condition 1 to "Formula is" and enter this formula:

   =MATCH(B1,$A:$A,0)

5. Click the Format... button and select a green background.

You should now see the green background applied to the matching cells in Sheet1.

Hiding the mirror column

1. Stay on Sheet1.
2. Right-click the header on column A and select "Hide".

This should automatically update Sheet1 whenever anything in Sheet2 is changed.

You can also use unionBy for 4.0.0 and later, as follows: let uniques = _.unionBy(data, 'id')

After looking at the code you're having typos, here is the updated code

var clicks = 0; // should be var not int
    function clickME() {
        clicks += 1;
        document.getElementById("clicks").innerHTML = clicks; //getElementById() not getElementByID() Which you corrected in edit
 }

Demo

Note: Don't use in-built handlers, as .click() is javascript function try giving different name like clickME()

This is link by Tomas has a well written script to zip contents of a folder.

To make it work just copy the script into a batch file and execute it by specifying the folder to be zipped(source).

No need to mention destination directory as it is defaulted in the script to Desktop ("%USERPROFILE%\Desktop")

Copying the script here, just incase the web-link is down:

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION

SET sourceDirPath=%1
IF [%2] EQU [] (
  SET destinationDirPath="%USERPROFILE%\Desktop"
) ELSE (
  SET destinationDirPath="%2"
)
IF [%3] EQU [] (
  SET destinationFileName="%~n1%.zip"
) ELSE (
  SET destinationFileName="%3"
)
SET tempFilePath=%TEMP%\FilesToZip.txt
TYPE NUL > %tempFilePath%

FOR /F "DELIMS=*" %%i IN ('DIR /B /S /A-D "%sourceDirPath%"') DO (
  SET filePath=%%i
  SET dirPath=%%~dpi
  SET dirPath=!dirPath:~0,-1!
  SET dirPath=!dirPath:%sourceDirPath%=!
  SET dirPath=!dirPath:%sourceDirPath%=!
  ECHO .SET DestinationDir=!dirPath! >> %tempFilePath%
  ECHO "!filePath!" >> %tempFilePath%
)

MAKECAB /D MaxDiskSize=0 /D CompressionType=MSZIP /D Cabinet=ON /D Compress=ON /D UniqueFiles=OFF /D DiskDirectoryTemplate=%destinationDirPath% /D CabinetNameTemplate=%destinationFileName%  /F %tempFilePath% > NUL 2>&1

I'd like to offer my version of option parsing, that allows for the following:

-s p1
--stage p1
-w somefolder
--workfolder somefolder
-sw p1 somefolder
-e=hello

Also allows for this (could be unwanted):

-s--workfolder p1 somefolder
-se=hello p1
-swe=hello p1 somefolder

You have to decide before use if = is to be used on an option or not. This is to keep the code clean(ish).

while [[ $# > 0 ]]
do
    key="$1"
    while [[ ${key+x} ]]
    do
        case $key in
            -s*|--stage)
                STAGE="$2"
                shift # option has parameter
                ;;
            -w*|--workfolder)
                workfolder="$2"
                shift # option has parameter
                ;;
            -e=*)
                EXAMPLE="${key#*=}"
                break # option has been fully handled
                ;;
            *)
                # unknown option
                echo Unknown option: $key #1>&2
                exit 10 # either this: my preferred way to handle unknown options
                break # or this: do this to signal the option has been handled (if exit isn't used)
                ;;
        esac
        # prepare for next option in this key, if any
        [[ "$key" = -? || "$key" == --* ]] && unset key || key="${key/#-?/-}"
    done
    shift # option(s) fully processed, proceed to next input argument
done

A more generic solution without function overloading than my previous one:

template<typename T>
std::string TypeOf(T){
    std::string Type="unknown";
    if(std::is_same<T,int>::value) Type="int";
    if(std::is_same<T,std::string>::value) Type="String";
    if(std::is_same<T,MyClass>::value) Type="MyClass";

    return Type;}

Here MyClass is user defined class. More conditions can be added here as well.

Example:

#include <iostream>



class MyClass{};


template<typename T>
std::string TypeOf(T){
    std::string Type="unknown";
    if(std::is_same<T,int>::value) Type="int";
    if(std::is_same<T,std::string>::value) Type="String";
    if(std::is_same<T,MyClass>::value) Type="MyClass";
    return Type;}


int main(){;
    int a=0;
    std::string s="";
    MyClass my;
    std::cout<<TypeOf(a)<<std::endl;
    std::cout<<TypeOf(s)<<std::endl;
    std::cout<<TypeOf(my)<<std::endl;

    return 0;}

Output:

int
String
MyClass

Lockheed Martin uses a 3-prefix naming scheme which was wonderful to work with, especially when reading others' code.

   Scope          Reference Type(*Case-by-Case)   Type

   member   m     pointer p                       integer n
   argument a     reference r                     short   n
   local    l                                     float   f
                                                  double  f
                                                  boolean b

So...

int A::methodCall(float af_Argument1, int* apn_Arg2)
{
    lpn_Temp = apn_Arg2;
    mpf_Oops = lpn_Temp;  // Here I can see I made a mistake, I should not assign an int* to a float*
}

Take it for what's it worth.

This is known as the "fragment identifier" and is typically used to identify a portion of an HTML document that sits within a fully qualified URL:

) AS source
PIVOT
(
    MAX([Value])
    FOR [Period] IN ([2000], [2001], [2002])
) as pvt

Another way,

SELECT ACCOUNT,
      MAX(CASE WHEN Period = '2000' THEN Value ELSE NULL END) [2000],
      MAX(CASE WHEN Period = '2001' THEN Value ELSE NULL END) [2001],
      MAX(CASE WHEN Period = '2002' THEN Value ELSE NULL END) [2002]
FROM tableName

To match either / or end of content, use (/|\z)

This only applies if you are not using multi-line matching (i.e. you're matching a single URL, not a newline-delimited list of URLs).

To put that with an updated version of what you had:

/(\S+?)/(\d{4}-\d{2}-\d{2})-(\d+)(/|\z)

Note that I've changed the start to be a non-greedy match for non-whitespace ( \S+? ) rather than matching anything and everything ( .* )

The Host Header tells the webserver which virtual host to use (if set up). You can even have the same virtual host using several aliases (= domains and wildcard-domains). In this case, you still have the possibility to read that header manually in your web app if you want to provide different behavior based on different domains addressed. This is possible because in your webserver you can (and if I'm not mistaken you must) set up one vhost to be the default host. This default vhost is used whenever the host header does not match any of the configured virtual hosts.

That means: You get it right, although saying "multiple hosts" may be somewhat misleading: The host (the addressed machine) is the same, what really gets resolved to the IP address are different domain names (including subdomains) that are also referred to as hostnames (but not hosts!).

Although not part of the question, a fun fact: This specification led to problems with SSL in early days because the web server has to deliver the certificate that corresponds to the domain the client has addressed. However, in order to know what certificate to use, the webserver should have known the addressed hostname in advance. But because the client sends that information only over the encrypted channel (which means: after the certificate has already been sent), the server had to assume you browsed the default host. That meant one ssl-secured domain per IP address / port-combination.

This has been overcome with Server Name Indication; however, that again breaks some privacy, as the server name is now transferred in plain text again, so every man-in-the-middle would see which hostname you are trying to connect to.

Although the webserver would know the hostname from Server Name Indication, the Host header is not obsolete, because the Server Name Indication information is only used within the TLS handshake. With an unsecured connection, there is no Server Name Indication at all, so the Host header is still valid (and necessary).

Another fun fact: Most webservers (if not all) reject your HTTP request if it does not contain exactly one Host header, even if it could be omitted because there is only the default vhost configured. That means the minimum required information in an http-(get-)request is the first line containing METHOD RESOURCE and PROTOCOL VERSION and at least the Host header, like this:

GET /someresource.html HTTP/1.1
Host: www.example.com

In the MDN Documentation on the "Host" header they actually phrase it like this:

A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.

As mentioned by Darrel Miller, the complete specs can be found in RFC7230.

For everyone saying to get the bytes, copy it to MemoryStream, etc. - if the content isn't expected to be larger than computer's memory should be reasonably be expected to allow, why not just use StreamReader's built in ReadLine() or ReadToEnd()? I saw these weren't even mentioned, and they do everything for you.

I had a use-case where I just wanted to store the path of a SQLite file from a FileDialogResult that the user picks during the synching/initialization process. My program then later needs to use this path when it is run for normal application processes. Maybe not the ideal way to capture/re-use the information, but it's not much different than writing to/reading from an .ini file - I just didn't want to set one up for one value. So I just read it from a flat, one-line text file. Here's what I did:

string filePath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
if (!filePath.EndsWith(@"\")) temppath += @"\"; // ensures we have a slash on the end
filePath = filePath.Replace(@"\\", @"\"); // Visual Studio escapes slashes by putting double-slashes in their results - this ensures we don't have double-slashes
filePath += "SQLite.txt";

string path = String.Empty;
FileStream fs = new FileStream(filePath, FileMode.Open);
StreamReader sr = new StreamReader(fs);
path = sr.ReadLine();  // can also use sr.ReadToEnd();
sr.Close();
fs.Close();
fs.Flush();

return path;

If you REALLY need a byte[] instead of a string for some reason, using my example, you can always do:

byte[] toBytes;
FileStream fs = new FileStream(filePath, FileMode.Open);
StreamReader sr = new StreamReader(fs);
toBytes = Encoding.ASCII.GetBytes(path);
sr.Close();
fs.Close();
fs.Flush();

return toBytes;

(Returning toBytes instead of path.)

If you don't want ASCII you can easily replace that with UTF8, Unicode, etc.

Update: Apparently possible by passing a flag to mysql_connect(). See Executing multiple SQL queries in one statement with PHP Nevertheless, any current reader should avoid using the mysql_-class of functions and prefer PDO.

You can't do that using the regular mysql-api in PHP. Just execute two queries. The second one will be so fast that it won't matter. This is a typical example of micro optimization. Don't worry about it.

For the record, it can be done using mysqli and the mysqli_multi_query-function.

Just to make a more comprehensive answer, the C way of iterating over a string can apply in Python, if you really wanna force a square peg into a round hole.

i = 0
while i < len(str):
    print str[i]
    i += 1

But then again, why do that when strings are inherently iterable?

for i in str:
    print i

What about this ? :

Data.indexOf(_.find(Data, function(element) {
  return element.name === 'John';
}));

Assuming you are using lodash or underscorejs.

In Laravel:

Add set_time_limit(0) line on top of query.

set_time_limit(0);

$users = App\User::all();

It helps you in different large queries but you should need to improve query optimise.

dtypes is a Pandas Series. That means it contains index & values attributes. If you only need the column names:

Verified the following on Virtualbox-5.0.24, Android_x86-4.4-r5. You get a screen similar to an 8" table. You can play around with the xxx in DPI=xxx, to change the resolution. xxx=100 makes it really small to match a real table exactly, but it may be too small when working with android in Virtualbox.

Given sheet 2:

ColumnA
-------
apple
orange

You can flag the rows in sheet 1 where a value exists in sheet 2:

ColumnA  ColumnB
-------  --------------
pear     =IF(ISERROR(VLOOKUP(A1,Sheet2!A:A,1,FALSE)),"Keep","Delete")
apple    =IF(ISERROR(VLOOKUP(A2,Sheet2!A:A,1,FALSE)),"Keep","Delete")
cherry   =IF(ISERROR(VLOOKUP(A3,Sheet2!A:A,1,FALSE)),"Keep","Delete")
orange   =IF(ISERROR(VLOOKUP(A4,Sheet2!A:A,1,FALSE)),"Keep","Delete")
plum     =IF(ISERROR(VLOOKUP(A5,Sheet2!A:A,1,FALSE)),"Keep","Delete")

The resulting data looks like this:

ColumnA  ColumnB
-------  --------------
pear     Keep
apple    Delete
cherry   Keep
orange   Delete
plum     Keep

You can then easily filter or sort sheet 1 and delete the rows flagged with 'Delete'.

i think the simple solution is:

sh /dir/* > ./result.txt

The goal of the OP is that he wants to define inline scripts into his Partial View, which I assume that this script is specific only to that Partial View, and have that block included into his script section.

I get that he wants to have that Partial View to be self contained. The idea is similar to components when using Angular.

My way would be to just keep the scripts inside the Partial View as is. Now the problem with that is when calling Partial View, it may execute the script in there before all other scripts (which is typically added to the bottom of the layout page). In that case, you just have the Partial View script wait for the other scripts. There are several ways to do this. The simplest one, which I've used before, is using an event on body.

On my layout, I would have something on the bottom like this:

// global scripts
<script src="js/jquery.min.js"></script>
// view scripts
@RenderSection("scripts", false)
// then finally trigger partial view scripts
<script>
  (function(){
    document.querySelector('body').dispatchEvent(new Event('scriptsLoaded'));
  })();
</script>

Then on my Partial View (at the bottom):

<script>
  (function(){
    document.querySelector('body').addEventListener('scriptsLoaded', function() {

      // .. do your thing here

    });
  })();
</script>

Another solution is using a stack to push all your scripts, and call each one at the end. Other solution, as mentioned already, is RequireJS/AMD pattern, which works really well also.

PermGen stands for Permanent Generation.

Here is a brief blurb on DDJ

Your solution is correct, but there is some redundancy in your regex.
The similar result can also be obtained from the following regex:

^([A-Z]{3})$

The {3} indicates that the [A-Z] must appear exactly 3 times.

I can think of one unfortunate side-effect. In java embedded databases, the number of ids you can have with a 32bit id field is 2^31, not 2^32 (~2billion, not ~4billion).

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
   weightSelected = [pickerArray objectAtIndex:row];
}

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

Yes.

the answer below is good too... I was looking for that today but couldn't find it. Thanks

You will not write code into a static block that needs to be invoked anywhere in your program. If the purpose of the code is to be invoked then you must place it in a method.

You can write static initializer blocks to initialize static variables when the class is loaded but this code can be more complex..

A static initializer block looks like a method with no name, no arguments, and no return type. Since you never call it it doesn't need a name. The only time its called is when the virtual machine loads the class.

$path = 'image.jpg';
echo substr(strrchr($path, "."), 1); //jpg

You override the rich comparison operators in your object.

class MyClass:
 def __lt__(self, other):
      # return comparison
 def __le__(self, other):
      # return comparison
 def __eq__(self, other):
      # return comparison
 def __ne__(self, other):
      # return comparison
 def __gt__(self, other):
      # return comparison
 def __ge__(self, other):
      # return comparison

Like this:

    def __eq__(self, other):
        return self._id == other._id

You can use the ansible.cfg file, it should look like this (There are other parameters which you might want to include):

[defaults]
inventory = <PATH TO INVENTORY FILE>
remote_user = <YOUR USER>
private_key_file =  <PATH TO KEY_FILE>

Hope this saves you some typing

Intersect the targets with the haystack and make sure the intersection is precisely equal to the targets:

$haystack = array(...);

$target = array('foo', 'bar');

if(count(array_intersect($haystack, $target)) == count($target)){
    // all of $target is in $haystack
}

Note that you only need to verify the size of the resulting intersection is the same size as the array of target values to say that $haystack is a superset of $target.

To verify that at least one value in $target is also in $haystack, you can do this check:

 if(count(array_intersect($haystack, $target)) > 0){
     // at least one of $target is in $haystack
 }

gonbe's answer is excellent. But still I want to mention that file:/// = ~/../../, not $SPARK_HOME. Hope this could save some time for newbs like me.

There are also some ST2/ST3 Plugins for such tasks. I do like these two:

• Delete Blank Lines (also available via Package Control)
• Trailing Spaces (also available via Package Control)

The first one has two methods for removing empty/unnecessary lines. One of them called Delete Surplus Blank Lines which is cool. It removes only those lines that are followed by another empty line

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

For my interactive day-to-day gitting (where I diff the working tree against the HEAD all the time, and would like to have untracked files included in the diff), add -N/--intent-to-add is unusable, because it breaks git stash.

So here's my git diff replacement. It's not a particularly clean solution, but since I really only use it interactively, I'm OK with a hack:

d() {
    if test "$#" = 0; then
        (
            git diff --color
            git ls-files --others --exclude-standard |
                while read -r i; do git diff --color -- /dev/null "$i"; done
        ) | `git config --get core.pager`
    else
        git diff "$@"
    fi
}

Typing just d will include untracked files in the diff (which is what I care about in my workflow), and d args... will behave like regular git diff.

Notes:

• We're using the fact here that git diff is really just individual diffs concatenated, so it's not possible to tell the d output from a "real diff" -- except for the fact that all untracked files get sorted last.
• The only problem with this function is that the output is colorized even when redirected; but I can't be bothered to add logic for that.
• I couldn't find any way to get untracked files included by just assembling a slick argument list for git diff. If someone figures out how to do this, or if maybe a feature gets added to git at some point in the future, please leave a note here!

You can also simply convert a 2D array into hash using:

1.9.3p362 :005 > a= [[1,2],[3,4]]

 => [[1, 2], [3, 4]]

1.9.3p362 :006 > h = Hash[a]

 => {1=>2, 3=>4} 

Add .idea and *.iml to .gitignore, you don't need those files to successfully import and compile the project.

you can use .css method of jquery..

If you just want the difference in years, there's:

SELECT EXTRACT(YEAR FROM date1) - EXTRACT(YEAR FROM date2) FROM mytable

Or do you want fractional years as well?

SELECT (date1 - date2) / 365.242199 FROM mytable

365.242199 is 1 year in days, according to Google.

Try this:

subset(studentdata, Drink=='water')

that should do it.

If you are using MasterPages and Content pages in your app - you also have the option of putting the ScriptManager on the Masterpage and then every ContentPage that uses that MasterPage will NOT need a script manager added. If you need some of the special configurations of the ScriptManager - like javascript file references - you can use a ScriptManagerProxy control on the content page that needs it.

I would point out that (functionally) there's a BIG difference between cycles and/or multiple paths in the SCHEMA and the DATA. While cycles and perhaps multipaths in the DATA could certainly complicated processing and cause performance problems (cost of "properly" handling), the cost of these characteristics in the schema should be close to zero.

Since most apparent cycles in RDBs occur in hierarchical structures (org chart, part, subpart, etc.) it is unfortunate that SQL Server assumes the worst; i.e., schema cycle == data cycle. In fact, if you're using RI constraints you can't actually build a cycle in the data!

I suspect the multipath problem is similar; i.e., multiple paths in the schema don't necessarily imply multiple paths in the data, but I have less experience with the multipath problem.

Of course if SQL Server did allow cycles it'd still be subject to a depth of 32, but that's probably adequate for most cases. (Too bad that's not a database setting however!)

"Instead of Delete" triggers don't work either. The second time a table is visited, the trigger is ignored. So, if you really want to simulate a cascade you'll have to use stored procedures in the presence of cycles. The Instead-of-Delete-Trigger would work for multipath cases however.

Celko suggests a "better" way to represent hierarchies that doesn't introduce cycles, but there are tradeoffs.

You should use scaleY instead.

ul {_x000D_
  background-color: #eee;_x000D_
  transform: scaleY(0);    _x000D_
  transform-origin: top;_x000D_
  transition: transform 0.26s ease;_x000D_
}_x000D_
p:hover ~ ul {_x000D_
  transform: scaleY(1);_x000D_
}

<p>Hover This</p>_x000D_
<ul>_x000D_
  <li>Coffee</li>_x000D_
  <li>Tea</li>_x000D_
  <li>Milk</li>_x000D_
</ul>

I've made a vendor prefixed version of the above code on jsfiddle, and changed your jsfiddle to use scaleY instead of height.

Per the documentation from GitHub regarding GFM syntax highlighted code blocks

We use Linguist to perform language detection and syntax highlighting. You can find out which keywords are valid in the languages YAML file.

Rendered on GitHub, console makes the lines after the console blue. bash, sh, or shell don't seem to "highlight" much ...and you can use posh for PowerShell or CMD.

Forget about using success and error method.

Both methods have been deprecated in angular 1.4. Basically, the reason behind the deprecation is that they are not chainable-friendly, so to speak.

With the following example, I'll try to demonstrate what I mean about success and error being not chainable-friendly. Suppose we call an API that returns a user object with an address:

User object:

{name: 'Igor', address: 'San Francisco'}

Call to the API:

$http.get('/user')
    .success(function (user) {
        return user.address;   <---  
    })                            |  // you might expect that 'obj' is equal to the
    .then(function (obj) {   ------  // address of the user, but it is NOT

        console.log(obj); // -> {name: 'Igor', address: 'San Francisco'}
    });
};

What happened?

Because success and error return the original promise, i.e. the one returned by $http.get, the object passed to the callback of the then is the whole user object, that is to say the same input to the preceding success callback.

If we had chained two then, this would have been less confusing:

$http.get('/user')
    .then(function (user) {
        return user.address;  
    })
    .then(function (obj) {  
        console.log(obj); // -> 'San Francisco'
    });
};

git reset --hard 4a155e5 Will move the HEAD back to where you want to be. There may be other references ahead of that time that you would need to remove if you don't want anything to point to the history you just deleted.

If you want to add your custom headers to ALL requests, you can change the defaults on $httpProvider to always add this header…

app.config(['$httpProvider', function ($httpProvider) {
    $httpProvider.defaults.headers.common = { 
        'Authorization': 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==',
        'Accept': 'application/json;odata=verbose'
      };
}]);

I posted a bunch of stuff in comments I think it warrants its own answer.

As everyone says here, using equals() depends on the order. If you don't care about order, you have 3 options.

Option 1

Use containsAll(). This option is not ideal, in my opinion, because it offers worst case performance, O(n^2).

Option 2

There are two variations to this:

2a) If you don't care about maintaining the order ofyour lists... use Collections.sort() on both list. Then use the equals(). This is O(nlogn), because you do two sorts, and then an O(n) comparison.

2b) If you need to maintain the lists' order, you can copy both lists first. THEN you can use solution 2a on both the copied lists. However this might be unattractive if copying is very expensive.

This leads to:

Option 3

If your requirements are the same as part 2b, but copying is too expensive. You can use a TreeSet to do the sorting for you. Dump each list into its own TreeSet. It will be sorted in the set, and the original lists will remain intact. Then perform an equals() comparison on both TreeSets. The TreeSetss can be built in O(nlogn) time, and the equals() is O(n).

Take your pick :-).

EDIT: I almost forgot the same caveat that Laurence Gonsalves points out. The TreeSet implementation will eliminate duplicates. If you care about duplicates, you will need some sort of sorted multiset.

To complete @SamSaffron's answer :

You can use class_name with either foreign_key or inverse_of. I personally prefer the more abstract declarative, but it's really just a matter of taste :

class BlogPost
  has_many :images, class_name: "BlogPostImage", inverse_of: :blog_post  
end

and you need to make sure you have the belongs_to attribute on the child model:

class BlogPostImage
  belongs_to :blog_post
end

I tried this and it worked.

app.get('/', function (req, res) {
    res.sendFile('public/index.html', { root: __dirname });
});

Do you realize, that CLAMP255 returns 0 for v < 0 and 255 for v >= 0?
IMHO, CLAMP255 should be defined as:

#define CLAMP255(v) (v > 255 ? 255 : (v < 0 ? 0 : v))

Difference: If v is not greater than 255 and not less than 0: return v instead of 255

HTML5 element can give dotted underline so the beneath text will have dotted line rather than regular underline. And the title attribute creates a tool tip for the user when they hover their cursor over the element:

NOTE: The dotted border/underline is shown by default in Firefox and Opera, but IE8, Safari, and Chrome need a line of CSS:

<abbr title="Hyper Text Markup Language">HTML</abbr>

Given that commonly 1 = true and 0 = false, all you need to do is count the number of rows, and cast to a boolean.

Hence, your posted code only needs a COUNT() function added:

SELECT CAST(COUNT(1) AS BIT) AS Expr1
FROM [User]
WHERE (UserID = 20070022)

This code snippet worked for me. I have an issue with the parsing batch of XML files. I had to encode them to 'iso-8859-5'

import xml.etree.ElementTree as ET

tree = ET.parse(filename, parser = ET.XMLParser(encoding = 'iso-8859-5'))

If you want to build DOM you can use jsdom.

There's also cheerio, it has the jQuery interface and it's a lot faster than older versions of jsdom, although these days they are similar in performance.

You might wanna have a look at htmlparser2, which is a streaming parser, and according to its benchmark, it seems to be faster than others, and no DOM by default. It can also produce a DOM, as it is also bundled with a handler that creates a DOM. This is the parser that is used by cheerio.

parse5 also looks like a good solution. It's fairly active (11 days since the last commit as of this update), WHATWG-compliant, and is used in jsdom, Angular, and Polymer.

And if you want to parse HTML for web scraping, you can use YQL¹. There is a node module for it. YQL I think would be the best solution if your HTML is from a static website, since you are relying on a service, not your own code and processing power. Though note that it won't work if the page is disallowed by the robot.txt of the website, YQL won't work with it.

If the website you're trying to scrape is dynamic then you should be using a headless browser like phantomjs. Also have a look at casperjs, if you're considering phantomjs. And you can control casperjs from node with SpookyJS.

Beside phantomjs there's zombiejs. Unlike phantomjs that cannot be embedded in nodejs, zombiejs is just a node module.

There's a nettuts+ toturial for the latter solutions.

¹ Since Aug. 2014, YUI library, which is a requirement for YQL, is no longer actively maintained, source

You could also use a URI template. If you structured your request into a restful URL Spring could parse the provided value from the url.

HTML

<li>
    <a id="byParameter" 
       class="textLink" href="<c:url value="/mapping/parameter/bar />">By path, method,and
           presence of parameter</a>
</li>

Controller

@RequestMapping(value="/mapping/parameter/{foo}", method=RequestMethod.GET)
public @ResponseBody String byParameter(@PathVariable String foo) {
    //Perform logic with foo
    return "Mapped by path + method + presence of query parameter! (MappingController)";
}

Spring URI Template Documentation

You need to put package-info.java in your generated jaxb package. Its content should be something like that

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.example.org/StudentOperations/")
package generated.marsh;

Maybe you simply want the standard format string "N", as in

number.ToString("N")

It will use thousand separators, and a fixed number of fractional decimals. The symbol for thousands separators and the symbol for the decimal point depend on the format provider (typically CultureInfo) you use, as does the number of decimals (which will normally by 2, as you require).

If the format provider specifies a different number of decimals, and if you don't want to change the format provider, you can give the number of decimals after the N, as in .ToString("N2").

Edit: The sizes of the groups between the commas are governed by the

CultureInfo.CurrentCulture.NumberFormat.NumberGroupSizes

array, given that you don't specify a special format provider.

What do we mean by org.hibernate.exception.SQLGrammarException?

Implementation of JDBCException indicating that the SQL sent to the database server was invalid (syntax error, invalid object references, etc).

and in my words there is a kind of Grammar mistake inside of your hibernate.cfg.xml configuration file,

it happens when you write wrong schema defination property name inside, like below example:

<property name="hibernate.connection.hbm2ddl.auto">create</property>

which supposed to be like:

<property name="hibernate.hbm2ddl.auto">create</property>

Just to give a short, working example to see an effect of their difference

new Thread(foo).Start();

private void foo()
{
  this.Dispatcher.BeginInvoke(DispatcherPriority.Normal,
    (ThreadStart)delegate()
    {
        myTextBox.Text = "bing";
        Thread.Sleep(TimeSpan.FromSeconds(3));
    });
  MessageBox.Show("done");
}

If use BeginInvoke, MessageBox pops simultaneous to the text update. If use Invoke, MessageBox pops after the 3 second sleep. Hence, showing the effect of an asynchronous (BeginInvoke) and a synchronous (Invoke) call.

I think the problem is you have to use the ! to unbundle identifier

I have

override func prepareForSegue(segue: UIStoryboardSegue?, sender: AnyObject?) {
        if segue!.identifier == "Details" {
            let viewController:ViewController = segue!.destinationViewController as ViewController
            let indexPath = self.tableView.indexPathForSelectedRow()
            viewController.pinCode = self.exams[indexPath.row]

        }

    }

My understanding is that without the ! you just get a true or false value

What all of these answers do not highlight is that when comparing a value to $null, you have to put $null on the left-hand side, otherwise you may get into trouble when comparing with a collection-type value. See: https://github.com/nightroman/PowerShellTraps/blob/master/Basic/Comparison-operators-with-collections/looks-like-object-is-null.ps1

$value = @(1, $null, 2, $null)
if ($value -eq $null) {
    Write-Host "$value is $null"
}

The above block is (unfortunately) executed. What's even more interesting is that in Powershell a $value can be both $null and not $null:

$value = @(1, $null, 2, $null)
if (($value -eq $null) -and ($value -ne $null)) {
    Write-Host "$value is both $null and not $null"
}

So it is important to put $null on the left-hand side to make these comparisons work with collections:

$value = @(1, $null, 2, $null)
if (($null -eq $value) -and ($null -ne $value)) {
    Write-Host "$value is both $null and not $null"
}

I guess this shows yet again the power of Powershell !

TL;DR:

git checkout HEAD path/to/file
git stash apply

Long version:

You get this error because of the uncommited changes that you want to overwrite. Undo these changes with git checkout HEAD. You can undo changes to a specific file with git checkout HEAD path/to/file. After removing the cause of the conflict, you can apply as usual.

Just adding my suggestion for a resolution, I had a copy of a VM server for developing and testing, I created the database on that with 'sa' having ownership on the db.

I then restored the database onto the live VM server but I was getting the same error mentioned even though the data was still returning correctly. I looked up the 'sa' user mappings and could see it wasn't mapped to the database when I tried to apply the mapping I got a another error "Fix: Cannot use the special principal ‘sa’. Microsoft SQL Server, Error: 15405". so I ran this instead

ALTER AUTHORIZATION ON DATABASE::dbname TO sa

I rechecked the user mappings and it was now assigned to my db and it fixed a lot of access issues for me.

You can easily make your own 'AlertView' and use it everywhere.

alertView("You really want this?");

Implement it once:

private void alertView( String message ) {
 AlertDialog.Builder dialog = new AlertDialog.Builder(context);
 dialog.setTitle( "Hello" )
       .setIcon(R.drawable.ic_launcher)
       .setMessage(message)
//     .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
//      public void onClick(DialogInterface dialoginterface, int i) {
//          dialoginterface.cancel();   
//          }})
      .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialoginterface, int i) {   
        }               
        }).show();
 }

<router-outlet [node]="..."></router-outlet> 

is just invalid. The component added by the router is added as sibling to <router-outlet> and does not replace it.

The top answers above did not work for me (restarting, updating to version 1.1.18 ... I was already updated, deleting the temp files, clearning NuGet cache etc).

What I discovered is that I had differing references to MSTest.TestAdapter and MSTest.Framework in different test projects (my solution has two). One was pointed to 1.1.18 like...

packages.config

<package id="MSTest.TestAdapter" version="1.1.18" targetFramework="net461" />
<package id="MSTest.TestFramework" version="1.1.18" targetFramework="net461" />

... but another has the references to 1.1.11. Some of the answers above lead to this discovery when two versions of the libraries showed up in my temp directory (%TEMP%\VisualStudioTestExplorerExtensions\) after restarting Visual Studio.

Solution

Simply updating my packages.config to the 1.1.18 version is what restored my unit tests functionality in VS. It appears that there are some bugs that do not allow side-by-side references of the MSTest libraries. Hope this helps you.

More info:

• Visual Studio 2017 Ent: 15.5.6 (I had updated from 15.0.1 with hopes to fix this issue, but I had it in both)

The simplest is to just give the 'trans' (formerly 'formatter' argument the name of the log function:

m + geom_boxplot() + scale_y_continuous(trans='log10')

EDIT: Or if you don't like that, then either of these appears to give different but useful results:

m <- ggplot(diamonds, aes(y = price, x = color), log="y")
m + geom_boxplot() 
m <- ggplot(diamonds, aes(y = price, x = color), log10="y")
m + geom_boxplot()

EDIT2 & 3: Further experiments (after discarding the one that attempted successfully to put "$" signs in front of logged values):

fmtExpLg10 <- function(x) paste(round_any(10^x/1000, 0.01) , "K $", sep="")
ggplot(diamonds, aes(color, log10(price))) + 
  geom_boxplot() + 
  scale_y_continuous("Price, log10-scaling", trans = fmtExpLg10)

Note added mid 2017 in comment about package syntax change:

scale_y_continuous(formatter = 'log10') is now scale_y_continuous(trans = 'log10') (ggplot2 v2.2.1)

It is not possible.
ObjectA.PropertyA.PropertyB will fail if ObjectA is null due to null dereferencing, which is an error.

if(ObjectA != null && ObjectA.PropertyA ... works due to short circuiting, ie ObjectA.PropertyA will never be checked if ObjectA is null.

The first way you propose is the best and most clear with intent. If anything you could try to redesign without having to rely on so many nulls.

Modern solution - works in all browsers and IE9+

caniuse - browser support.

Update

As I continue to recieve upvotes on this, I think it is reasonable to remember that this answer is 4 years old. Web has grown in a really fast pace, so please be mindful about this answer.

I had the same issue recently and researched about the subject.

The solution given is called long polling, and to correctly use it you must be sure that your AJAX request has a "large" timeout and to always make this request after the current ends (timeout, error or success).

Long Polling - Client

Here, to keep code short, I will use jQuery:

function pollTask() { 

    $.ajax({

        url: '/api/Polling',
        async: true,            // by default, it's async, but...
        dataType: 'json',       // or the dataType you are working with
        timeout: 10000,          // IMPORTANT! this is a 10 seconds timeout
        cache: false

    }).done(function (eventList) {  

       // Handle your data here
       var data;
       for (var eventName in eventList) {

            data = eventList[eventName];
            dispatcher.handle(eventName, data); // handle the `eventName` with `data`

       }

    }).always(pollTask);

}

It is important to remember that (from jQuery docs):

In jQuery 1.4.x and below, the XMLHttpRequest object will be in an invalid state if the request times out; accessing any object members may throw an exception. In Firefox 3.0+ only, script and JSONP requests cannot be cancelled by a timeout; the script will run even if it arrives after the timeout period.

Long Polling - Server

It is not in any specific language, but it would be something like this:

function handleRequest () {  

     while (!anythingHappened() || hasTimedOut()) { sleep(2); }

     return events();

} 

Here, hasTimedOut will make sure your code does not wait forever, and anythingHappened, will check if any event happend. The sleep is for releasing your thread to do other stuff while nothing happens. The events will return a dictionary of events (or any other data structure you may prefer) in JSON format (or any other you prefer).

It surely solves the problem, but, if you are concerned about scalability and perfomance as I was when researching, you might consider another solution I found.

Solution

Use sockets!

On client side, to avoid any compatibility issues, use socket.io. It tries to use socket directly, and have fallbacks to other solutions when sockets are not available.

On server side, create a server using NodeJS (example here). The client will subscribe to this channel (observer) created with the server. Whenever a notification has to be sent, it is published in this channel and the subscriptor (client) gets notified.

If you don't like this solution, try APE (Ajax Push Engine).

Hope I helped.

UPDATE ANDROID 10 AND HIGHER

Start an activity from service (foreground or background) is no longer allowed.

There are still some restrictions that can be seen in the documentation

https://developer.android.com/guide/components/activities/background-starts

When we want to take Integer as inputs
For just 3 inputs as in your case:

import java.util.Scanner;
Scanner scan = new Scanner(System.in);
int a,b,c;
a = scan.nextInt();
b = scan.nextInt();
c = scan.nextInt();

For more number of inputs we can use a loop:

import java.util.Scanner;
Scanner scan = new Scanner(System.in);
int a[] = new int[n]; //where n is the number of inputs
for(int i=0;i<n;i++){
    a[i] = scan.nextInt();    
}

Its really helped me to dynamically generate ids of showDetailItem for the below code.

<af:forEach id="fe1" items="#{viewScope.bean.tranTypeList}" var="ttf" varStatus="ttfVs" > 
<af:showDetailItem  id ="divIDNo${ttfVs.count}" text="#{ttf.trandef}"......>

if you execute this line <af:outputText value="#{ttfVs}"/> prints the below:

{index=3, count=4, last=false, first=false, end=8, step=1, begin=0}

Check if your project files are read-only. Remove the read-only property by right clicking on the project folder and select properties. In the properties screen remove the read-only checkbox. I came across the same problem, and this solved it for me.

You can do this with the code below, and the code in your question was actually very close to what you needed, all you have to do is call the cmap object you have.

import matplotlib

cmap = matplotlib.cm.get_cmap('Spectral')

rgba = cmap(0.5)
print(rgba) # (0.99807766255210428, 0.99923106502084169, 0.74602077638401709, 1.0)

For values outside of the range [0.0, 1.0] it will return the under and over colour (respectively). This, by default, is the minimum and maximum colour within the range (so 0.0 and 1.0). This default can be changed with cmap.set_under() and cmap.set_over().

For "special" numbers such as np.nan and np.inf the default is to use the 0.0 value, this can be changed using cmap.set_bad() similarly to under and over as above.

Finally it may be necessary for you to normalize your data such that it conforms to the range [0.0, 1.0]. This can be done using matplotlib.colors.Normalize simply as shown in the small example below where the arguments vmin and vmax describe what numbers should be mapped to 0.0 and 1.0 respectively.

import matplotlib

norm = matplotlib.colors.Normalize(vmin=10.0, vmax=20.0)

print(norm(15.0)) # 0.5

A logarithmic normaliser (matplotlib.colors.LogNorm) is also available for data ranges with a large range of values.

(Thanks to both Joe Kington and tcaswell for suggestions on how to improve the answer.)

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

The documentation for templating is partial, I watched the source.

The _.template function has 3 arguments:

1. String text : the template string
2. Object data : the evaluation data
3. Object settings : local settings, the _.templateSettings is the global settings object

If no data (or null) given, than a render function will be returned. It has 1 argument:

1. Object data : same as the data above

There are 3 regex patterns and 1 static parameter in the settings:

1. RegExp evaluate : "<%code%>" in template string
2. RegExp interpolate : "<%=code%>" in template string
3. RegExp escape : "<%-code%>"
4. String variable : optional, the name of the data parameter in the template string

The code in an evaluate section will be simply evaluated. You can add string from this section with the __p+="mystring" command to the evaluated template, but this is not recommended (not part of the templating interface), use the interpolate section instead of that. This type of section is for adding blocks like if or for to the template.

The result of the code in the interpolate section will added to the evaluated template. If null given back, then empty string will added.

The escape section escapes html with _.escape on the return value of the given code. So its similar than an _.escape(code) in an interpolate section, but it escapes with \ the whitespace characters like \n before it passes the code to the _.escape. I don't know why is that important, it's in the code, but it works well with the interpolate and _.escape - which doesn't escape the white-space characters - too.

By default the data parameter is passed by a with(data){...} statement, but this kind of evaluating is much slower than the evaluating with named variable. So naming the data with the variable parameter is something good...

For example:

var html = _.template(
    "<pre>The \"<% __p+=_.escape(o.text) %>\" is the same<br />" +
        "as the  \"<%= _.escape(o.text) %>\" and the same<br />" +
        "as the \"<%- o.text %>\"</pre>",
    {
        text: "<b>some text</b> and \n it's a line break"
    },
    {
        variable: "o"
    }
);

$("body").html(html);

results

The "<b>some text</b> and 
 it's a line break" is the same
as the "<b>some text</b> and 
 it's a line break" and the same
as the "<b>some text</b> and 
 it's a line break"

You can find here more examples how to use the template and override the default settings: http://underscorejs.org/#template

By template loading you have many options, but at the end you always have to convert the template into string. You can give it as normal string like the example above, or you can load it from a script tag, and use the .html() function of jquery, or you can load it from a separate file with the tpl plugin of require.js.

Another option to build the dom tree with laconic instead of templating.

I think this is what you are looking for -

select Address1+Address2 as CompleteAddress from YourTable
where Address1+Address2 like '%YourSearchString%'

To prevent a compound word being created when we append address1 with address2, you can use this -

select Address1 + ' ' + Address2 as CompleteAddress from YourTable 
where Address1 + ' ' + Address2 like '%YourSearchString%'

So, '123 Center St' and 'Apt 3B' will not be '123 Center StApt 3B' but will be '123 Center St Apt 3B'.

You might want to look at the Pyxplot plotting package http://pyxplot.org.uk which has very similar syntax to gnuplot, but with the rough edges cleaned up. It handles colors and line styles quite neatly, and homogeneously between x11 and eps/pdf terminals.

The Pyxplot script for what you want to do above would be:

set style 1 lt 1 lw 3 color red
set style 2 lt 1 lw 3 color blue
set style 3 lt 2 lw 3 color red
set style 4 lt 2 lw 3 color blue
plot 'data1.dat' using 1:3 w l style 1,\
  'data1.dat' using 1:4 w l style 2,\
  'data2.dat' using 1:3 w l style 3,\
  'data2.dat' using 1:4 w l style 4`

Before I answer this, I'd like to point out that Chrome and IE 10+ actually supports calc with viewport units.

FIDDLE (In IE10+)

Solution (for other browsers): box-sizing

1) Start of by setting your height as 100vh.

2) With box-sizing set to border-box - add a padding-top of 75vw. This means that the padding will be part f the inner height.

3) Just offset the extra padding-top with a negative margin-top

FIDDLE

div
{
    /*height: calc(100vh - 75vw);*/
    height: 100vh;
    margin-top: -75vw;
    padding-top: 75vw;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    background: pink;
}

Unit test is usually done for a single functionality implemented in Software module. The scope of testing is entirely within this SW module. Unit test never fulfils the final functional requirements. It comes under whitebox testing methodology..

Whereas Integration test is done to ensure the different SW module implementations. Testing is usually carried out after module level integration is done in SW development.. This test will cover the functional requirements but not enough to ensure system validation.

mysqlclient is a fork of MySQLdb and can serve as a drop-in replacement with Python 3.4 support. If you have trouble building it on Windows, you can download it from Christoph Gohlke's Unofficial Windows Binaries for Python Extension Packages

I'm using GNU Make from the GnuWin32 project, see http://gnuwin32.sourceforge.net/ but there haven't been any updates for a while now, so I'm not sure on this project's status.

It seems you can cheat a bit using jetxee's algorithm. He is finding the first three toes fine, and you should be able to guess where the fourth is based off that.

Here is the example of selector. If you use eclipse , it does not suggest something when you click ctrl and space both :/ you must type it.

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/btn_default_pressed" android:state_pressed="true" />
<item android:drawable="@drawable/btn_default_selected"
    android:state_focused="true"
    android:state_enabled="true"
    android:state_window_focused="true"  />
<item android:drawable="@drawable/btn_default_normal" />

If the paths for the files in question are the same in the two repos and you're wanting to bring over just one file or a small set of related files, one easy way to do this is to use git cherry-pick.

The first step is to bring the commits from the other repo into your own local repo using git fetch <remote-url>. This will leave FETCH_HEAD pointing to the head commit from the other repo; if you want to preserve a reference to that commit after you've done other fetches you may want to tag it with git tag other-head FETCH_HEAD.

You will then need to create an initial commit for that file (if it doesn't exist) or a commit to bring the file to a state that can be patched with the first commit from the other repo you want to bring in. You may be able to do this with a git cherry-pick <commit-0> if commit-0 introduced the files you want, or you may need to construct the commit 'by hand'. Add -n to the cherry-pick options if you need to modify the initial commit to, e.g., drop files from that commit you don't want to bring in.

After that, you can continue to git cherry-pick subsequent commits, again using -n where necessary. In the simplest case (all commits are exactly what you want and apply cleanly) you can give the full list of commits on the cherry-pick command line: git cherry-pick <commit-1> <commit-2> <commit-3> ....

Yes, you can even change it by triggering an event

<input type='text' name='pass'  onclick="(this.type='password')" />


<input type="text" placeholder="date" onfocusin="(this.type='date')" onfocusout="(this.type='text')">

From the post above, I think the best way is

1. Have a fixed div with width: 100%
2. Inside the div, make a new static div with margin-left: auto and margin-right: auto, or for table make it align="center".
3. Tadaaaah, you have centered your fixed div now

Hope this will help.

You need to use delegates and protocols. Here is a site with an example http://iosdevelopertips.com/objective-c/the-basics-of-protocols-and-delegates.html

Working with me v.good Reference

public class ShakeEventListener implements SensorEventListener {
public final static int SHAKE_LIMIT = 15;
public final static int LITTLE_SHAKE_LIMIT = 5;

private SensorManager mSensorManager;
private float mAccel = 0.00f;
private float mAccelCurrent = SensorManager.GRAVITY_EARTH;
private float mAccelLast = SensorManager.GRAVITY_EARTH;

private ShakeListener listener;

    public void onShake();

    listener = l;

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

Links to relevant Microsoft documentation (for PowerShell 5.0; tho versions 3.0 and 4.0 are also available at the links):

• about_Scripts
• about_Functions
• about_Functions_Advanced_Parameters

Try out Ctrl + z But it will kill the process, not suspend it.

Setting autoPlay: true didn't work for me. But on setting autoPlay: 5000 it worked.

Add 0.001 first to the number and then call setScale(2, RoundingMode.ROUND_HALF_UP)

Code example:

public static void main(String[] args) {
    BigDecimal a = new BigDecimal("10.12445").add(new BigDecimal("0.001"));
    BigDecimal b = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println(b);
}

Instead of overwriting the html every time, just toggle the class.

$('#click_advance').click(function() {
    $('#display_advance').toggle('1000');
    $("i", this).toggleClass("icon-circle-arrow-up icon-circle-arrow-down");
});

This may be of some help (do not literally write out the backslashes '\' in the commands, they are meant to indicate that "everything has to be on one line"):

It seems that all the commands (in grey) take any type of key file (in green) as "in" argument. Which is nice.

Here are the commands again for easier copy-pasting:

openssl rsa                                                -in $FF -out $TF
openssl rsa -aes256                                        -in $FF -out $TF
openssl pkcs8 -topk8 -nocrypt                              -in $FF -out $TF
openssl pkcs8 -topk8 -v2 aes-256-cbc -v2prf hmacWithSHA256 -in $FF -out $TF

and

openssl rsa -check -in $FF
openssl rsa -text  -in $FF

If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()

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:

A thing worth noting is that setting .State = EntityState.Deleted does not trigger automatically detected change. (archive)

If you are OK with HTML5 it can be accomplished without any JavaScript code at all...

<input type="number" name="textWeight" id="txtWeight" max="5" min="0" />

Otherwise, something like...

var input = document.getElementById('txtWeight');

input.addEventListener('change', function(e) {
    var num = parseInt(this.value, 10),
        min = 0,
        max = 100;

    if (isNaN(num)) {
        this.value = "";
        return;
    }

    this.value = Math.max(num, min);
    this.value = Math.min(num, max);
});

This will only reset the values when the input looses focus, and clears out any input that can't be parsed as an integer...

OBLIGATORY WARNING

You should always perform adequate server-side validation on inputs, regardless of client-side validation.

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

Most of the suggestions are now, no longer valid.

The correct fix as of today, is to use the 'button' layout.

eg. <div class="fb-like" data-href="https://developers.facebook.com/docs/plugins/" data-layout="button" data-action="like" data-show-faces="true" data-share="false"></div>

The FB Docs, seem not to be fully updated yet... if you scroll down you'll see they state only 3 layouts are available, yet the dropdown suggests 4.

This means you can now use a less hacky solution!

Basename wild cards were introduced in Java 6; i.e. "foo/*" means all ".jar" files in the "foo" directory.

In earlier versions of Java that do not support wildcard classpaths, I have resorted to using a shell wrapper script to assemble a Classpath by 'globbing' a pattern and mangling the results to insert ':' characters at the appropriate points. This would be hard to do in a BAT file ...

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

echo "word1 word2" | cut -f 1 -d " "

cut cuts the 1st field (-f 1) from a list of fields delimited by the string " " (-d " ")

When comparing objects in Java, you make a semantic check, comparing the type and identifying state of the objects to:

• itself (same instance)
• itself (clone, or reconstructed copy)
• other objects of different types
• other objects of the same type
• null

Rules:

• Symmetry: a.equals(b) == b.equals(a)
• equals() always yields true or false, but never a NullpointerException, ClassCastException or any other throwable

Comparison:

• Type check: both instances need to be of the same type, meaning you have to compare the actual classes for equality. This is often not correctly implemented, when developers use instanceof for type comparison (which only works as long as there are no subclasses, and violates the symmetry rule when A extends B -> a instanceof b != b instanceof a).
• Semantic check of identifying state: Make sure you understand by which state the instances are identified. Persons may be identified by their social security number, but not by hair color (can be dyed), name (can be changed) or age (changes all the time). Only with value objects should you compare the full state (all non-transient fields), otherwise check only what identifies the instance.

For your Person class:

public boolean equals(Object obj) {

    // same instance
    if (obj == this) {
        return true;
    }
    // null
    if (obj == null) {
        return false;
    }
    // type
    if (!getClass().equals(obj.getClass())) {
        return false;
    }
    // cast and compare state
    Person other = (Person) obj;
    return Objects.equals(name, other.name) && Objects.equals(age, other.age);
}

Reusable, generic utility class:

public final class Equals {

    private Equals() {
        // private constructor, no instances allowed
    }

    /**
     * Convenience equals implementation, does the object equality, null and type checking, and comparison of the identifying state
     *
     * @param instance       object instance (where the equals() is implemented)
     * @param other          other instance to compare to
     * @param stateAccessors stateAccessors for state to compare, optional
     * @param <T>            instance type
     * @return true when equals, false otherwise
     */
    public static <T> boolean as(T instance, Object other, Function<? super T, Object>... stateAccessors) {
        if (instance == null) {
            return other == null;
        }
        if (instance == other) {
            return true;
        }
        if (other == null) {
            return false;
        }
        if (!instance.getClass().equals(other.getClass())) {
            return false;
        }
        if (stateAccessors == null) {
            return true;
        }
        return Stream.of(stateAccessors).allMatch(s -> Objects.equals(s.apply(instance), s.apply((T) other)));
    }
}

For your Person class, using this utility class:

public boolean equals(Object obj) {
    return Equals.as(this, obj, t -> t.name, t -> t.age);
}

Since I cannot comment on the answer, I'd build on Jin Izzraeel's answer

var myBuffer = [];
var str = 'Stack Overflow';
var buffer = new Buffer(str, 'utf16le');
for (var i = 0; i < buffer.length; i++) {
    myBuffer.push(buffer[i]);
}

console.log(myBuffer);

by saying that you could use this if you want to use a Node.js buffer in your browser.

Therefore, Tom Stickel's objection is not valid, and the answer is indeed a valid answer.

You should not be doing this. Instead, do:

test1.py:

 def print_test():
      print "I am a test"
      print "see! I do nothing productive."

service.py

#near the top
from test1 import print_test
#lots of stuff here
print_test()

The maximum name size is 30 characters because of the data dictionary which allows the storage only for 30 bytes

Why the map/lambda magic? Doesn't this work?

>>> foo = ['a', 'b', 'c']
>>> print(','.join(foo))
a,b,c
>>> print(','.join([]))

>>> print(','.join(['a']))
a

In case if there are numbers in the list, you could use list comprehension:

>>> ','.join([str(x) for x in foo])

or a generator expression:

>>> ','.join(str(x) for x in foo)

Add the JSON MIME type to IIS 6. Follow the directions at MSDN's Configure MIME Types (IIS 6.0).

• Extension: .json
• MIME type: application/json

Don't forget to restart IIS after the change.

UPDATE: There are easy ways to do this on IIS7 and newer. The op specifically asked for IIS6 help so I'm leaving this answer as-is. But this answer is still getting a lot of traffic even though IIS6 is very old now. Hopefully you're using something newer, so I wanted to mention that if you have a newer IIS7 or newer version see @ProVega's answer below for a simpler solution for those newer versions.

If you are using native javascript then you can use this code -

let ids = users.map(function(obj, index) {

    return obj.id;
})

console.log(ids); //[12, 14, 16, 18]

1. First of all, there is no difference between View.OnClickListener and OnClickListener. If you just use View.OnClickListener directly, then you don't need to write-

   import android.view.View.OnClickListener

2. You set an OnClickListener instance (e.g. myListener named object)as the listener to a view via setOnclickListener(). When a click event is fired, that myListener gets notified and it's onClick(View view) method is called. Thats where we do our own task. Hope this helps you.

There are 3 basic commands to compare files in unix:

1. cmp : This command is used to compare two files byte by byte and as any mismatch occurs,it echoes it on the screen.if no mismatch occurs i gives no response. syntax:$cmp file1 file2.

2. comm : This command is used to find out the records available in one but not in another

3. diff

I'm pretty new to iOS and Phonegap as well, but I was able to do this by adding in an eventListener. I did the same thing (using the example you reference), and couldn't get it to work. But this seemed to do the trick:

// Event listener to determine change (horizontal/portrait)
window.addEventListener("orientationchange", updateOrientation); 

function updateOrientation(e) {
switch (e.orientation)
{   
    case 0:
        // Do your thing
        break;

    case -90:
        // Do your thing
        break;

    case 90:
        // Do your thing
        break;

    default:
        break;
    }
}

You may have some luck searching the PhoneGap Google Group for the term "orientation".

One example I read about as an example on how to detect orientation was Pie Guy: (game, js file). It's similar to the code you've posted, but like you... I couldn't get it to work.

One caveat: the eventListener worked for me, but I'm not sure if this is an overly intensive approach. So far it's been the only way that's worked for me, but I don't know if there are better, more streamlined ways.

UPDATE fixed the code above, it works now

I would use this in HTML 5... Just sayin

#footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 60px;

}

It complains because it needs to use ssh instead of https but your git is still configured with https. so basically as others mentioned previously you need to either enable prompts or to configure git to use ssh instead of https. a simple way to do this by running the following:

git config --global --add url."[email protected]:".insteadOf "https://github.com/"

or if you already use ssh with git in your machine, you can safely edit ~/.gitconfig and add the following line at the very bottom

Note: This covers all SVC, source version control, that depends on what you exactly use, github, gitlab, bitbucket)

# Enforce SSH
[url "ssh://[email protected]/"]
  insteadOf = https://github.com/
[url "ssh://[email protected]/"]
        insteadOf = https://gitlab.com/
[url "ssh://[email protected]/"]
  insteadOf = https://bitbucket.org/

• If you want to keep password pompts disabled, you need to cache password. For more information on how to cache your github password on mac, windows or linux, please visit this page.

• For more information on how to add ssh to your github account, please visit this page.

Also, more importantly, if this is a private repository for a company or for your self, you may need to skip using proxy or checksum database for such repos to avoid exposing them publicly.

To do this, you need to set GOPRIVATE environment variable that controls which modules the go command considers to be private (not available publicly) and should therefore NOT use the proxy or checksum database.

The variable is a comma-separated list of patterns (same syntax of Go's path.Match) of module path prefixes. For example,

export GOPRIVATE=*.corp.example.com,github.com/mycompany/*

Or

go env -w GOPRIVATE=github.com/mycompany/*

• For more information on how to solve private packages/modules checksum validation issues, please read this article.
• For more information about go 13 modules and new enhancements, please check out Go 1.13 Modules Release notes.

One last thing not to forget to mention, you can still configure go get to authenticate and fetch over https, all you need to do is to add the following line to $HOME/.netrc

machine github.com login USERNAME password APIKEY

I would bet most users aren't the type of user that use the keyboard as a navigation control. Is it then acceptable to annoy the majority of your users for a small group that prefers to use keyboard navigation? Short answer — depends on who your users are.

Also, I don't see this experience in the same way in Firefox and Safari. So this argument seems to be mostly for IE. It all really depends on your user base and their level of knowledge — how they use the site.

If you really want to know where you are and you are a keyboard user, you can always look at the status bar as you key through the site.

In addition to the accepted answer by @Andreas Mueller, just want to add that as @tangy mentioned above:

StratifiedShuffleSplit most closely resembles train_test_split(stratify = y) with added features of:

1. stratify by default
2. by specifying n_splits, it repeatedly splits the data

Since today I know it: the best thing for text extraction from PDFs is TET, the text extraction toolkit. TET is part of the PDFlib.com family of products.

PDFlib.com is Thomas Merz's company. In case you don't recognize his name: Thomas Merz is the author of the "PostScript and PDF Bible".

TET's first incarnation is a library. That one can probably do everything Budda006 wanted, including positional information about every element on the page. Oh, and it can also extract images. It recombines images which are fragmented into pieces.

pdflib.com also offers another incarnation of this technology, the TET plugin for Acrobat. And the third incarnation is the PDFlib TET iFilter. This is a standalone tool for user desktops. Both these are free (as in beer) to use for private, non-commercial purposes.

And it's really powerful. Way better than Adobe's own text extraction. It extracted text for me where other tools (including Adobe's) do spit out garbage only.

I just tested the desktop standalone tool, and what they say on their webpage is true. It has a very good commandline. Some of my "problematic" PDF test files the tool handled to my full satisfaction.

This thing will from now on be my recommendation for every sophisticated and challenging PDF text extraction requirements.

TET is simply awesome. It detects tables. Inside tables, it identifies cells spanning multiple columns. It identifies table rows and contents of each table cell separately. It deals very well with hyphenations: it removes hyphens and restores complete words. It supports non-ASCII languages (including CJK, Arabic and Hebrew). When encountering ligatures, it restores the original characters...

Give it a try.

The -regex find expression matches the whole name, including the relative path from the current directory. For find . this always starts with ./, then any directories.

Also, these are emacs regular expressions, which have other escaping rules than the usual egrep regular expressions.

If these are all directly in the current directory, then

find . -regex '\./[a-f0-9\-]\{36\}\.jpg'

should work. (I'm not really sure - I can't get the counted repetition to work here.) You can switch to egrep expressions by -regextype posix-egrep:

find . -regextype posix-egrep -regex '\./[a-f0-9\-]{36}\.jpg'

(Note that everything said here is for GNU find, I don't know anything about the BSD one which is also the default on Mac.)

Cookie-Based Authentication

Cookies based Authentication works normally in these 4 steps-

1. The user provides a username and password in the login form and clicks Log In.
2. After the request is made, the server validate the user on the backend by querying in the database. If the request is valid, it will create a session by using the user information fetched from the database and store them, for each session a unique id called session Id is created ,by default session Id is will be given to client through the Browser.

3. Browser will submit this session Id on each subsequent requests, the session ID is verified against the database, based on this session id website will identify the session belonging to which client and then give access the request.

4. Once a user logs out of the app, the session is destroyed both client-side and server-side.

Had similar problems recently. Would suggest you carefully check if the user you're connecting with has proper authorizations on the remote machine.

You can review permissions using the following command.

Set-PSSessionConfiguration -ShowSecurityDescriptorUI -Name Microsoft.PowerShell

It fixed it for me.

See java.beans.ConstructorProperties, it's an annotation designed for doing exactly this.

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

If you need to set the user header string in the curl request, you can use the -H option to set user agent like:

Using a proxy tool like Charles Proxy really helps make short work of something like what you are asking. Here is what I do, using this SO page as an example (as of July 2015 using Charles version 3.10):

1. Get Charles Proxy running
2. Make web request using browser
3. Find desired request in Charles Proxy
4. Right click on request in Charles Proxy
5. Select 'Copy cURL Request'

You now have a cURL request you can run in a terminal that will mirror the request your browser made. Here is what my request to this page looked like (with the cookie header removed):

curl -H "Host: stackoverflow.com" -H "Cache-Control: max-age=0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36" -H "HTTPS: 1" -H "DNT: 1" -H "Referer: https://www.google.com/" -H "Accept-Language: en-US,en;q=0.8,en-GB;q=0.6,es;q=0.4" -H "If-Modified-Since: Thu, 23 Jul 2015 20:31:28 GMT" --compressed http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

I hope you use the java collection / java commons collections!

With an java.util.ArrayList you can do things like the following:

yourArrayList.remove(someObject);

yourArrayList.add(someObject);

Delete the .git directory in the root-directory of your repository if you only want to delete the git-related information (branches, versions).

If you want to delete everything (git-data, code, etc), just delete the whole directory.

.git directories are hidden by default, so you'll need to be able to view hidden files to delete it.

The way via unlist and matrix seems a bit convoluted, and requires you to hard-code the number of elements (this is actually a pretty big no-go. Of course you could circumvent hard-coding that number and determine it at run-time)

I would go a different route, and construct a data frame directly from the list that strsplit returns. For me, this is conceptually simpler. There are essentially two ways of doing this:

1. as.data.frame – but since the list is exactly the wrong way round (we have a list of rows rather than a list of columns) we have to transpose the result. We also clear the rownames since they are ugly by default (but that’s strictly unnecessary!):

   `rownames<-`(t(as.data.frame(strsplit(text, '\\.'))), NULL)
   

2. Alternatively, use rbind to construct a data frame from the list of rows. We use do.call to call rbind with all the rows as separate arguments:

   do.call(rbind, strsplit(text, '\\.'))
   

Both ways yield the same result:

     [,1] [,2] [,3]  [,4]
[1,] "F"  "US" "CLE" "V13"
[2,] "F"  "US" "CA6" "U13"
[3,] "F"  "US" "CA6" "U13"
[4,] "F"  "US" "CA6" "U13"
[5,] "F"  "US" "CA6" "U13"
[6,] "F"  "US" "CA6" "U13"
…

Clearly, the second way is much simpler than the first.

So I'm myself new to React and I found a way to do it.

This solution does not require any extra packages.

Step 1 ReactDocs

In the above docs they mention export in Shell and other options, the one I'll attempt to explain is using .env file

1.1 create Root/.env

#.env file
REACT_APP_SECRET_NAME=secretvaluehere123

Important notes it MUST start with REACT_APP_

1.2 Access ENV variable

#App.js file or the file you need to access ENV
<p>print env secret to HTML</p>
<pre>{process.env.REACT_APP_SECRET_NAME}</pre>

handleFetchData() { // access in API call
  fetch(`https://awesome.api.io?api-key=${process.env.REACT_APP_SECRET_NAME}`)
    .then((res) => res.json())
    .then((data) => console.log(data))
}

1.3 Build Env Issue

So after I did step 1.1|2 it was not working, then I found the above issue/solution. React read/creates env when is built so you need to npm run start every time you modify the .env file so the variables get updated.

You need to tell SQLPlus which database you want to log on to. Host String needs to be either a connection string or an alias configured in your TNSNames.ora file.

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

Try putting double quotes in your filepath variable

"\"E:/ABC/SEM 2/testfiles/all.txt\""

Check the permissions of the file or in any case consider renaming the folder to remove the space

For me following fixed the issue:

1. npm cache clear
2. Made sure that NPM & Git proxies are set properly

In this case Git proxy may not be required.

As, @Shaswat Rungta said: "I think the question is more about how to add it after the installation is over."

On my PC(Windows 7) I think that the command "Git Bash here" disappeard after I installed Visual Studio 2017.

I fixt this by downloading and installing Git again.

Note that the IEnumerable<T> allready implemented by the System.Collections so another approach is to derive your MyObjects class from System.Collections as a base class (documentation):

System.Collections: Provides the base class for a generic collection.

We can later make our own implemenation to override the virtual System.Collections methods to provide custom behavior (only for ClearItems, InsertItem, RemoveItem, and SetItem along with Equals, GetHashCode, and ToString from Object). Unlike the List<T> which is not designed to be easily extensible.

Example:

public class FooCollection : System.Collections<Foo>
{
    //...
    protected override void InsertItem(int index, Foo newItem)
    {
        base.InsertItem(index, newItem);     
        Console.Write("An item was successfully inserted to MyCollection!");
    }
}

public static void Main()
{
    FooCollection fooCollection = new FooCollection();
    fooCollection.Add(new Foo()); //OUTPUT: An item was successfully inserted to FooCollection!
}

Please note that driving from collection recommended only in case when custom collection behavior is needed, which is rarely happens. see usage.

Simplicity of this technique is stunning:
(This method has its implications though, but if you only need to center element regardless of flow of the rest of the content, it's just fine. Use with care)

Markup:

<div>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum accumsan tellus purus, et mollis nulla consectetur ac. Quisque id elit at diam convallis venenatis eget sed justo. Nunc egestas enim mauris, sit amet tempor risus ultricies in. Sed dignissim magna erat, vel laoreet tortor bibendum vitae. Ut porttitor tincidunt est imperdiet vestibulum. Vivamus id nibh tellus. Integer massa orci, gravida non imperdiet sed, consectetur ac quam. Nunc dignissim felis id tortor tincidunt, a eleifend nulla molestie. Phasellus eleifend leo purus, vel facilisis massa dignissim vitae. Pellentesque libero sapien, tincidunt ut lorem non, porta accumsan risus. Morbi tempus pharetra ex, vel luctus turpis tempus eu. Integer vitae sagittis massa, id gravida erat. Maecenas sed purus et magna tincidunt faucibus nec eget erat. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc nec mollis sem.</div>

And CSS:

div {
  color: white;
  background: red;
  padding: 15px;
  position: absolute;
  top: 50%;
  left: 50%;
  -ms-transform: translateX(-50%) translateY(-50%);
  -webkit-transform: translate(-50%,-50%);
  transform: translate(-50%,-50%);
}   

This will center element horizontally and vertically too. No negative margins, just power of transforms. Also we should already forget about IE8 shouldn't we?

Another option I like, which can be generalized once I start seeing the code not conform to DRY, is to use one controller that redirects to another controller.

public ActionResult ClientIdSearch(int cid)
{
  var action = String.Format("Details/{0}", cid);

  return RedirectToAction(action, "Accounts");
}

I find this allows me to apply my logic in one location and re-use it without have to sprinkle JavaScript in the views to handle this. And, as I mentioned I can then refactor for re-use as I see this getting abused.

Check it out -

<input type="button" id="btnclick" value="click" />
var intervalA;
        var intervalB;

        $(document).ready(function () {

            $('#btnclick').click(function () {
                blinkFont();

                setTimeout(function () {
                    clearInterval(intervalA);
                    clearInterval(intervalB);
                }, 5000);
            });
        });

        function blinkFont() {
            document.getElementById("blink").style.color = "red"
            document.getElementById("blink").style.background = "black"
            intervalA = setTimeout("blinkFont()", 500);
        }

        function setblinkFont() {
            document.getElementById("blink").style.color = "black"
            document.getElementById("blink").style.background = "red"
            intervalB = setTimeout("blinkFont()", 500);
        }

    </script>

    <div id="blink" class="live-chat">
        <span>This is blinking text and background</span>
    </div>

you can configure the coverage exclusion in the sonar properties, outside of the configuration of the jacoco plugin:

...
<properties>
    ....
    <sonar.exclusions>
        **/generated/**/*,
        **/model/**/*
    </sonar.exclusions>
    <sonar.test.exclusions>
        src/test/**/*
    </sonar.test.exclusions>
    ....
    <sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>
    <sonar.jacoco.reportPath>${project.basedir}/../target/jacoco.exec</sonar.jacoco.reportPath>
    <sonar.coverage.exclusions>
        **/generated/**/*,
        **/model/**/*
    </sonar.coverage.exclusions>
    <jacoco.version>0.7.5.201505241946</jacoco.version>
    ....
</properties>
....

and remember to remove the exclusion settings from the plugin

You might need to use a character by character (getc()) loop to ensure you have no buffer overflows and don't truncate the input.

I had this same problem. As Dedren says, the problem is not the query, but the form object's control source. Put [] around each objects Control Source. eg: Contol Source: [Product number], Control Source: Salesperson.[Salesperson number], etc.

Makita recomends going to the original table that you are referencing in your query and rename the field so that there are no spaces eg: SalesPersonNumber, ProductNumber, etc. This will solve many future problems as well. Best of Luck!

You can use functools.partial for this (as you suspected):

from functools import partial

def target(lock, iterable_item):
    for item in iterable_item:
        # Do cool stuff
        if (... some condition here ...):
            lock.acquire()
            # Write to stdout or logfile, etc.
            lock.release()

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    l = multiprocessing.Lock()
    func = partial(target, l)
    pool.map(func, iterable)
    pool.close()
    pool.join()

Example:

def f(a, b, c):
    print("{} {} {}".format(a, b, c))

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    a = "hi"
    b = "there"
    func = partial(f, a, b)
    pool.map(func, iterable)
    pool.close()
    pool.join()

if __name__ == "__main__":
    main()

Output:

hi there 1
hi there 2
hi there 3
hi there 4
hi there 5

/* I have done it this way, and also tested it */

Step 1 = Register custom cell class (in case of prototype cell in table) or nib (in case of custom nib for custom cell) for table like this in viewDidLoad method:

[self.yourTableView registerClass:[CustomTableViewCell class] forCellReuseIdentifier:@"CustomCell"];

OR

[self.yourTableView registerNib:[UINib nibWithNibName:@"CustomTableViewCell" bundle:nil] forCellReuseIdentifier:@"CustomCell"];

Step 2 = Use UITableView's "dequeueReusableCellWithIdentifier: forIndexPath:" method like this (for this, you must register class or nib) :

   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
            CustomTableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"CustomCell" forIndexPath:indexPath];

            cell.imageViewCustom.image = nil; // [UIImage imageNamed:@"default.png"];
            cell.textLabelCustom.text = @"Hello";

            dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
                // retrive image on global queue
                UIImage * img = [UIImage imageWithData:[NSData dataWithContentsOfURL:     [NSURL URLWithString:kImgLink]]];

                dispatch_async(dispatch_get_main_queue(), ^{

                    CustomTableViewCell * cell = (CustomTableViewCell *)[tableView cellForRowAtIndexPath:indexPath];
                  // assign cell image on main thread
                    cell.imageViewCustom.image = img;
                });
            });

            return cell;
        }

I think another way is to use recursion. Here is my code:

def gcd(a, b):
    if a > b:
        c = a - b
        gcd(b, c)
    elif a < b:
        c = b - a
        gcd(a, c)
    else:
        return a

http://msdn.microsoft.com/en-us/library/system.string.split.aspx

Example from the docs:

string source = "[stop]ONE[stop][stop]TWO[stop][stop][stop]THREE[stop][stop]";
string[] stringSeparators = new string[] {"[stop]"};
string[] result;

// ...
result = source.Split(stringSeparators, StringSplitOptions.None);

foreach (string s in result)
{
    Console.Write("'{0}' ", String.IsNullOrEmpty(s) ? "<>" : s);
}

== operator compares two object references to check whether they refer to same instance. This also, will return true on successful match.for example

public class Example{
public static void main(String[] args){
String s1 = "Java";
String s2 = "Java";
String s3 = new string ("Java");
test(Sl == s2)     //true
test(s1 == s3)      //false
}}

above example == is a reference comparison i.e. both objects point to the same memory location

String equals() is evaluates to the comparison of values in the objects.

   public class EqualsExample1{
   public static void main(String args[]){
   String s = "Hell";
   String s1 =new string( "Hello");
   String s2 =new string( "Hello");
   s1.equals(s2);    //true
    s.equals(s1) ;   //false
    }}

above example It compares the content of the strings. It will return true if string matches, else returns false.

There is no runtime performance cost to using var. Though, I would suspect there to be a compiling performance cost as the compiler needs to infer the type, though this will most likely be negligable.

The child process environment is lost in the moment it ceases to exist, and moving the environment content from there to the parent is somewhat tricky.

You probably need to spawn a shell script (you can generate one dynamically to /tmp) which will output the virtualenv environment variables to a file, which you then read in the parent Python process and put in os.environ.

Or you simply parse the activate script in using for the line in open("bin/activate"), manually extract stuff, and put in os.environ. It is tricky, but not impossible.

foreach($data as $value)
{
    $value["transaction_date"] = date('d/m/Y',$value["transaction_date"]);
}
return $data;

Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing

#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()

You can't do this, which is by design. The Django framework authors intended a strict separation of presentation code from data logic. Filtering models is data logic, and outputting HTML is presentation logic.

So you have several options. The easiest is to do the filtering, then pass the result to render_to_response. Or you could write a method in your model so that you can say {% for object in data.filtered_set %}. Finally, you could write your own template tag, although in this specific case I would advise against that.

The error is because you are including the script links at two places which will do the override and re-initialization of date-picker

<meta charset="utf-8">_x000D_
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />_x000D_

$(document).ready(function() {_x000D_
    $('.dateinput').datepicker({ format: "yyyy/mm/dd" });_x000D_

<!-- Placed at the end of the document so the pages load faster -->_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>

So exclude either src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"

or src="http://code.jquery.com/ui/1.11.0/jquery-ui.js"

It will work..

I think the better answer for this questions is

array_diff() 

because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.

Whereas

array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.

To find distinct in field_1 in collection but we want some WHERE condition too than we can do like following :

db.your_collection_name.distinct('field_1', {WHERE condition here and it should return a document})

So, find number distinct names from a collection where age > 25 will be like :

db.your_collection_name.distinct('names', {'age': {"$gt": 25}})

Hope it helps!

With css:

.img {
    display:table-cell;
    max-width:...px;
    max-height:...px;
    width:100%;
}

From version 9.1.4 you only need to import ReactiveFormsModule

https://angular.io/guide/reactive-forms

Close, you can use

$('#select_2 option:selected').html()

This could help. It requires the footer height to be a fixed number. Basically, you have a div inside the footer div with it's normal content, with position: absolute, and then the image with position: relative, a negative z-index so it stays "below" everything, and a negative top value of the footer's height minus the image height (in my example, 50px - 600px = -550px). Tested in Chrome 8, FireFox 3.6 and IE 9.

You can use the title attribute, e.g. if you want to have a Tooltip over a text, just make:

<span title="This is a Tooltip">This is a text</span>

It depends on what you want to test:

• for a string, you can use If strName = vbNullString or IF strName = "" or Len(strName) = 0 (last one being supposedly faster)
• for an object, you can use If myObject is Nothing
• for a recordset field, you could use If isnull(rs!myField)
• for an Excel cell, you could use If range("B3") = "" or IsEmpty(myRange)

Extended discussion available here (for Access, but most of it works for Excel as well).

EDIT: this will case errors with jquery to happen, plus some other inconveniences. YOU SHOULD NOT USE IT: (perhaps if one could add a privaate method instead of a public property function, this would be OK, but don't have the time now). Community wikied

do not use:

Even though javascript's object by default doesn't have the count function, classes are easily extendable, and one can add it oneself:

Object.prototype.count = function () {
    var count = 0;
    for(var prop in this) {
        if(this.hasOwnProperty(prop))
            count = count + 1;
    }
    return count;
}

So that after that one can execute

var object = {'key1': 'val1', 'key2':'val2', 'key3':'val3'};
console.log(object.count()); // 3

As a conclusion, if you want count functionality in objects, you need to copy the code from code block 1, and paste it early in execution time ( before you call the count ).

Let me know if that works for you!

Regards, Pedro

Another more efficient way to do is just use @Value

@Value("classpath:sss.json")
private Resource resource;

and after that you can just get the file this way

File file = resource.getFile();

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

1) If a DataFrame has got Nan and Non Null values and you want to find whether the DataFrame
is empty or not then try this code.
2) when this situation can happen? 
This situation happens when a single function is used to plot more than one DataFrame 
which are passed as parameter.In such a situation the function try to plot the data even 
when a DataFrame is empty and thus plot an empty figure!.
It will make sense if simply display 'DataFrame has no data' message.
3) why? 
if a DataFrame is empty(i.e. contain no data at all.Mind you DataFrame with Nan values 
is considered non empty) then it is desirable not to plot but put out a message :
Suppose we have two DataFrames df1 and df2.
The function myfunc takes any DataFrame(df1 and df2 in this case) and print a message 
if a DataFrame is empty(instead of plotting):

df1                     df2
col1 col2           col1 col2 
Nan   2              Nan  Nan 
2     Nan            Nan  Nan  

and the function:

def myfunc(df):
  if (df.count().sum())>0: ##count the total number of non Nan values.Equal to 0 if DataFrame is empty
     print('not empty')
     df.plot(kind='barh')
  else:
     display a message instead of plotting if it is empty
     print('empty')

>>> lst = list(range(165))
>>> lst[0::10]
[0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160]

Note that this is around 100 times faster than looping and checking a modulus for each element:

$ python -m timeit -s "lst = list(range(1000))" "lst1 = [x for x in lst if x % 10 == 0]"
1000 loops, best of 3: 525 usec per loop
$ python -m timeit -s "lst = list(range(1000))" "lst1 = lst[0::10]"
100000 loops, best of 3: 4.02 usec per loop

I don't think there's one that's complete in the standard Java classes; HttpURLConnection is missing quite a few codes, like HTTP 100/Continue.

There's a complete list in the Apache HttpComponents, though:
org.apache.http.HttpStatus (replaced org.apache.commons.HttpClient.HttpStatus from Apache Http Client, which reached end of life)

my code has this tag

meta http-equiv="X-UA-Compatible" content="IE=7" />

is there a way where i can skip this tag and yet layouts get displayed well and fine using that tag the display will work upto IE 7 but i want to run it wel in further versions...

JSON (= JavaScript Object Notation), is a lightweight and fast mechanism to convert Javascript objects into a string and vice versa.

Since Javascripts objects consists of key/value pairs its very easy to use and access JSON that way.

So if we have an object:

var myObj = {
    foo:   'bar',
    base:  'ball',
    deep:  {
       java:  'script'
    }
};

We can convert that into a string by calling window.JSON.stringify(myObj); with the result of "{"foo":"bar","base":"ball","deep":{"java":"script"}}".

The other way around, we would call window.JSON.parse("a json string like the above");.

JSON.parse() returns a javascript object/array on success.

alert(myObj.deep.java);  // 'script'

window.JSON is not natively available in all browser. Some "older" browser need a little javascript plugin which offers the above mentioned functionality. Check http://www.json.org for further information.

There's always cmd. It may be less annoying if you have trouble quoting arguments to start-process:

cmd /c start /wait notepad

Or

notepad | out-host

you can use ls -1

ls -l will also do the work

Checkout https://mrin9.github.io/RapiPdf a custom element with plenty of customization and localization feature.

Disclaimer: I am the author of this package

After trying a lot of things I find a way that works. I share it here if it is useful to anyone. You can see it here working: http://jsbin.com/iquviq/30/edit

.content {
        width: 200px;
        height: 600px;
        background-color: blue;
        position: absolute; /*Can also be `fixed`*/
        left: 0;
        right: 0;
        top: 0;
        bottom: 0;
        margin: auto;
        /*Solves a problem in which the content is being cut when the div is smaller than its' wrapper:*/
        max-width: 100%;
        max-height: 100%;
        overflow: auto;
}

This reply is on a very old question to help others facing this issue.

I face this failed error while I were working on my Java project using IntelliJ IDEA IDE.

Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install (default-cli) on project getpassword: The packaging for this project did not assign a file to the build artifact

this failed happens, when I choose install:install under Plugins - install, as pointed with red arrow in below image.

Once I run the selected install under Lifecycle as illustrated above, the issue gone, and my maven install compile build successfully.

This cross-browser lib seems safer - just zoom and moz-transform won't cover as many browsers as jquery.transform2d's scale().

http://louisremi.github.io/jquery.transform.js/

For example

$('#div').css({ transform: 'scale(.5)' });

Update

OK - I see people are voting this down without an explanation. The other answer here won't work in old Safari (people running Tiger), and it won't work consistently in some older browsers - that is, it does scale things but it does so in a way that's either very pixellated or shifts the position of the element in a way that doesn't match other browsers.

http://www.browsersupport.net/CSS/zoom

Or just look at this question, which this one is likely just a dupe of:

complete styles for cross browser CSS zoom

No need to write own css, there is an library called "Bootstrap css" by calling that in your HTML head section, we can achieve many stylings,Here is an example: If you want to provide two column in a row, you can simply do the following:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">_x000D_
_x000D_
<div class="row">_x000D_
  <div class="col-md-6">Content</div>_x000D_
  <div class="col-md-6">Content</div>_x000D_
</div>

Here md stands for medium device,,you can use col-sm-6 for smaller devices and col-xs-6 for extra small devices

Try this in your constructor

MainActivity maniActivity = (MainActivity)context;
EditText firstName = (EditText) maniActivity.findViewById(R.id.display_name);

If you don't give any position to parent then by default it takes static. If you want to understand that difference refer to this example

Example 1::

http://jsfiddle.net/Cr9KB/1/

   #mainall
{

    background-color:red;
    height:150px;
    overflow:scroll
}

Here parent class has no position so element is placed according to body.

Example 2::

http://jsfiddle.net/Cr9KB/2/

#mainall
{
    position:relative;
    background-color:red;
    height:150px;
    overflow:scroll
}

In this example parent has relative position hence element are positioned absolute inside relative parent.
