I would do like below, where $products is the actual array given in the problem at the very beginning.

print_r(
  array_search("breville-variable-temperature-kettle-BKE820XL", 
  array_map(function($product){return $product["slug"];},$products))
);

Do not use rand(); use new C++11 facilities (e.g. std::mt19937, std::uniform_int_distribution, etc.) instead.

You can use code like this (live here on Ideone):

#include <iostream>
#include <random>
using namespace std;

int main()
{
    // Random seed
    random_device rd;

    // Initialize Mersenne Twister pseudo-random number generator
    mt19937 gen(rd());

    // Generate pseudo-random numbers
    // uniformly distributed in range (1, 100)
    uniform_int_distribution<> dis(1, 100);

    // Generate ten pseudo-random numbers
    for (int i = 0; i < 10; i++)
    {
        int randomX = dis(gen);
        cout << "\nRandom X = " << randomX;
    }
}

P.S.

Consider watching this video from Going Native 2013 conference for more details about rand()-related problems:

rand() Considered Harmful

You can use PadLeft

var newString = Your_String.PadLeft(4, '0');

Updated Answer for Node.js ~>0.8

Node is able to concatenate buffers on its own now.

var newBuffer = Buffer.concat([buffer1, buffer2]);

Old Answer for Node.js ~0.6

I use a module to add a .concat function, among others:

https://github.com/coolaj86/node-bufferjs

I know it isn't a "pure" solution, but it works very well for my purposes.

python formula now uses python3(v3.6.5 for now), brew will link the directory:

/usr/local/opt/python -> ../Cellar/python/3.6.5

it will also link the binary:

/usr/local/bin/python3 -> ../Cellar/python/3.6.5/bin/python3

If you still need to use python2.x, use:

brew install python@2

To use homebrew's python, just put its directory in PATH, for bash:

export PATH="/usr/local/opt/python/libexec/bin:$PATH"

for fish:

set -x PATH /usr/local/opt/python/libexec/bin $PATH

Note:

1. doing this will shadow the system default version of python
2. homebrew used to link python to /usr/local/share/python in older versions.

In SQL Server 2008,2012,2014 you can insert multiple rows using a single SQL INSERT statement.

 INSERT INTO TableName ( Column1, Column2 ) VALUES
    ( Value1, Value2 ), ( Value1, Value2 )

Another way

INSERT INTO TableName (Column1, Column2 )
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2
UNION ALL
SELECT Value1 ,Value2

1. Create a new package.
2. Move your files from the default package to the new one.

Here is a little combination of @Regexident Option 1 and @Garett answers, to get a powerful string cutter between a prefix and suffix, with MORE...ANDMORE words on it.

NSString *haystack = @"MOREvalue:hello World:valueANDMORE";
NSString *prefix = @"value:";
NSString *suffix = @":value";
NSRange prefixRange = [haystack rangeOfString:prefix];
NSRange suffixRange = [[haystack substringFromIndex:prefixRange.location+prefixRange.length] rangeOfString:suffix];
NSRange needleRange = NSMakeRange(prefixRange.location+prefix.length, suffixRange.location);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle);

Since you've already received help on the query, I'll take a poke at your syntax question:

The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join and on clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.

Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:

select
 count(*)
from Table1 as t1
join Table2 as t2
    join Table3 as t3
    on t2.Key = t3.Key                   -- join #1
    and t2.Key2 = t3.Key2 
on t1.DifferentKey = t3.DifferentKey     -- join #2  

This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:

select
 count(*)
from Table1 as t1
    join Table3 as t3
        join Table2 as t2
        on t2.Key = t3.Key                   -- join #1
        and t2.Key2 = t3.Key2   
    on t1.DifferentKey = t3.DifferentKey     -- join #2

Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.

My answer comes quite late because I'm a pretty new developer. This is what you can do:

Location.select(:name, :website, :city).find(row.id)

Btw, this is Rails 4

#include <windows.h>

double PCFreq = 0.0;
__int64 CounterStart = 0;

void StartCounter()
{
    LARGE_INTEGER li;
    if(!QueryPerformanceFrequency(&li))
    cout << "QueryPerformanceFrequency failed!\n";

    PCFreq = double(li.QuadPart)/1000.0;

    QueryPerformanceCounter(&li);
    CounterStart = li.QuadPart;
}
double GetCounter()
{
    LARGE_INTEGER li;
    QueryPerformanceCounter(&li);
    return double(li.QuadPart-CounterStart)/PCFreq;
}

int main()
{
    StartCounter();
    Sleep(1000);
    cout << GetCounter() <<"\n";
    return 0;
}

This program should output a number close to 1000 (windows sleep isn't that accurate, but it should be like 999).

The StartCounter() function records the number of ticks the performance counter has in the CounterStart variable. The GetCounter() function returns the number of milliseconds since StartCounter() was last called as a double, so if GetCounter() returns 0.001 then it has been about 1 microsecond since StartCounter() was called.

If you want to have the timer use seconds instead then change

PCFreq = double(li.QuadPart)/1000.0;

to

PCFreq = double(li.QuadPart);

or if you want microseconds then use

PCFreq = double(li.QuadPart)/1000000.0;

But really it's about convenience since it returns a double.

You haven't posted the findvertex method, but Access Reading Violation with an offset like 0x00000048 means that the Vertex* f; in your getCost function is receiving null, and when trying to access the member adj in the null Vertex pointer (that is, in f), it is offsetting to adj (in this case, 72 bytes ( 0x48 bytes in decimal )), it's reading near the 0 or null memory address.

Doing a read like this violates Operating-System protected memory, and more importantly means whatever you're pointing at isn't a valid pointer. Make sure findvertex isn't returning null, or do a comparisong for null on f before using it to keep yourself sane (or use an assert):

assert( f != null ); // A good sanity check

EDIT:

If you have a map for doing something like a find, you can just use the map's find method to make sure the vertex exists:

Vertex* Graph::findvertex(string s)
{
    vmap::iterator itr = map1.find( s );
    if ( itr == map1.end() )
    {
        return NULL;
    }
    return itr->second;
}

Just make sure you're still careful to handle the error case where it does return NULL. Otherwise, you'll keep getting this access violation.

Just install Google Repository form your sdk manager and than restart Android Studio.

Even though I'm somewhat late answering the question:

You can now use WebElement.isDisplayed() to check if an element is visible.

Note:

There are many reasons why an element could be invisible. Selenium tries cover most of them, but there are edge cases where it does not work as expected.

For example, isDisplayed() does return false if an element has display: none or opacity: 0, but at least in my test, it does not reliably detect if an element is covered by another due to CSS positioning.

Try the following API for phone number validation. Also this will return the Country, Area and Provider

demo https://libphonenumber.appspot.com/

git https://github.com/googlei18n/libphonenumber/releases/tag/v8.9.0

It worked for me, but the exe4j can leave a signature when you double click the .exe application

1. You must download Android SDK from this link.

2. You can really put it anywhere, but the best place at least for me was right in the YOUR USERNAME folder root.

3. Then you need to set the path by copying the below text, but edit your username into the path, copy the text into Terminal by hitting command+spacebar type terminal. export PATH = ${PATH}:/Users/**YOURUSERNAME**/android-sdk/platform-tools/

4. Verify ADB works by hitting command+spacebar and type terminal, and type ADB.

There you go. You have ADB setup on MAC OS X. It works on latest MAC OS X 10.10.3.

The best I've seen is Zend Guard.

You can also define a class for the bullets you want to show, so in the CSS:

ul {list-style:none; list-style-type:none; list-style-image:none;}

And in the HTML you just define which lists to show:

<ul style="list-style:disc;">

Or you alternatively define a CSS class:

.show-list {list-style:disc;}

Then apply it to the list you want to show:

<ul class="show-list">

All other lists won't show the bullets...

Since you've already looked into strtok just continue down the same path and split your string using space (' ') as a delimiter, then use something as realloc to increase the size of the array containing the elements to be passed to execvp.

See the below example, but keep in mind that strtok will modify the string passed to it. If you don't want this to happen you are required to make a copy of the original string, using strcpy or similar function.

char    str[]= "ls -l";
char ** res  = NULL;
char *  p    = strtok (str, " ");
int n_spaces = 0, i;


/* split string and append tokens to 'res' */

while (p) {
  res = realloc (res, sizeof (char*) * ++n_spaces);

  if (res == NULL)
    exit (-1); /* memory allocation failed */

  res[n_spaces-1] = p;

  p = strtok (NULL, " ");
}

/* realloc one extra element for the last NULL */

res = realloc (res, sizeof (char*) * (n_spaces+1));
res[n_spaces] = 0;

/* print the result */

for (i = 0; i < (n_spaces+1); ++i)
  printf ("res[%d] = %s\n", i, res[i]);

/* free the memory allocated */

free (res);

res[0] = ls
res[1] = -l
res[2] = (null)

To do it in the storyboard, you need to use an image for the button.

Alternatively you can do it in code:

 btn.layer.cornerRadius = 10
 btn.clipsToBounds = true

You can use two <div> elements:

• One is a container (it is the one which you originally wanted the background image to appear at).

• The second one is contained within. You set its size to the size of the background image (or the size you wish to be appearing).

The contained div is then set to be positioned absolute. This way it does not interfere with the normal flow of items in the containing div.

It enables you to use sprite images efficiently.

A 32-bit unsigned int has a range from 0 to 4,294,967,295. 0 to 65535 would be a 16-bit unsigned.

An unsigned long long (and, on a 64-bit implementation, possibly also ulong and possibly uint as well) have a range (at least) from 0 to 18,446,744,073,709,551,615 (2⁶⁴-1). In theory it could be greater than that, but at least for now that's rare to nonexistent.

As a workaround, you may use...

Windows Powershell ISE

As the Powershell script editor does not seems to have a buffer limitation in its read-eval-print-loop part (the "blue" part). And with Powershell you may execute DOS commands as well.

PS. I understand this answer is a bit aside the original question, however I believe it is good to mention as it is a good workaround.

I dealt with this before & had posted in the spring forums.

The advice we received was to use a type of SQlQuery. Here's an example of what we did when trying to get a value out of a DB that might not be there.

@Component
public class FindID extends MappingSqlQuery<Long> {

        @Autowired
        public void setDataSource(DataSource dataSource) {

                String sql = "Select id from address where id = ?";

                super.setDataSource(dataSource);

                super.declareParameter(new SqlParameter(Types.VARCHAR));

                super.setSql(sql);

                compile();
        }

        @Override
        protected Long mapRow(ResultSet rs, int rowNum) throws SQLException {
                return rs.getLong(1);
        }

In the DAO then we just call...

Long id = findID.findObject(id);

Not clear on performance, but it works and is neat.

java.sql.Timestamp is a subclass of java.util.Date. So, just upcast it.

Date dtStart = resultSet.getTimestamp("dtStart");
Date dtEnd = resultSet.getTimestamp("dtEnd");

Using SimpleDateFormat and creating Joda DateTime should be straightforward from this point on.

If your library name is say libxyz.so and it is located on path say:

/home/user/myDir

then to link it to your program:

g++ -L/home/user/myDir -lxyz myprog.cpp -o myprog

Firstly, be sure where your python directory. It is normally in C:\Python27. If yours is different then change it from the below command.

If after you install it python still isn’t recognized, then in PowerShell enter this:

[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User")

Close PowerShell and then start it again to make sure Python now runs. If it doesn’t, restart may be required.

This should do it:

Here is a way which allows to remove points after a certain number of points plotted:

import matplotlib.pyplot as plt
# generate axes object
ax = plt.axes()

# set limits
plt.xlim(0,10) 
plt.ylim(0,10)

for i in range(10):        
     # add something to axes    
     ax.scatter([i], [i]) 
     ax.plot([i], [i+1], 'rx')

     # draw the plot
     plt.draw() 
     plt.pause(0.01) #is necessary for the plot to update for some reason

     # start removing points if you don't want all shown
     if i>2:
         ax.lines[0].remove()
         ax.collections[0].remove()

I just spent hours to fix a similar issue. The problem in my case, was the the

max_input_vars = "1000"

by default, in the php.ini. I had a really huge form without uploads. php.ini is set to upload_max_filesize = "100M" and post_max_size = "108M" and it was surely not the issue in my case. PHP behavior is the same for max_input_vars when it exceeds 1000 variables in the form. It returns and empty _POST array. I wish I could have found that one hours, and hours ago.

In Data Source (on the left of Visual Studio) right click on the database, then Configure Data Source With Wizard. A new window will appear, expand the Connection string, you can find the connection string in there

The proper solution to resolve this issue is by following the steps

. Update Visual studio if you have older version to 15.5.4 (Optional)

2. Remove all binding redirects from web.config

3. Add this to the csproj file:

 <PropertyGroup>
  <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
  <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
</PropertyGroup>

4. Build.

5. In the bin folder, there should be a (WebAppName).dll.config file.

6. It should have redirects in it. Copy these to the web.config

7. Remove the above snipped from the csproj file again

8. It should work

I have seen problems with the "for each" using objects and prototype and arrays

my understanding is that the for each is for properties of objects and NOT arrays

I had the same error, but while I was connected and other previous statements in a script ran fine before! (So the connection was already open and some successful statements ran fine in auto-commit mode) The error was reproducable for some minutes. Then it had just disappeared. I don't know if somebody or some internal mechanism did some maintenance work or similar within this time - maybe.

Some more facts of my env:

• 11.2
• connected as: sys as sysdba
• operations involved ... reading from all_tables, all_views and granting select on them for another user

For me, the problem occurs when I've downloaded macOS Compressed Archive which underlying directory contains

jdk-11.0.8.jdk
- Contents
  - Home
    - bin
    - ...
  - MacOS
  - _CodeSignature

So, to solve the problem, JAVA_HOME should be pointed directly to /Path-to-JDK/Contents/Home.

Here is a quick summary of the segues and an example for each type.

Show - Pushes the destination view controller onto the navigation stack, sliding overtop from right to left, providing a back button to return to the source - or if not embedded in a navigation controller it will be presented modally
Example: Navigating inboxes/folders in Mail

Show Detail - For use in a split view controller, replaces the detail/secondary view controller when in an expanded 2 column interface, otherwise if collapsed to 1 column it will push in a navigation controller
Example: In Messages, tapping a conversation will show the conversation details - replacing the view controller on the right when in a two column layout, or push the conversation when in a single column layout

Present Modally - Presents a view controller in various animated fashions as defined by the Presentation option, covering the previous view controller - most commonly used to present a view controller that animates up from the bottom and covers the entire screen on iPhone, or on iPad it's common to present it as a centered box that darkens the presenting view controller
Example: Selecting Touch ID & Passcode in Settings

Popover Presentation - When run on iPad, the destination appears in a popover, and tapping anywhere outside of this popover will dismiss it, or on iPhone popovers are supported as well but by default it will present the destination modally over the full screen
Example: Tapping the + button in Calendar

Custom - You may implement your own custom segue and have control over its behavior

The deprecated segues are essentially the non-adaptive equivalents of those described above. These segue types were deprecated in iOS 8: Push, Modal, Popover, Replace.

For more info, you may read over the Using Segues documentation which also explains the types of segues and how to use them in a Storyboard. Also check out Session 216 Building Adaptive Apps with UIKit from WWDC 2014. They talked about how you can build adaptive apps using these new Adaptive Segues, and they built a demo project that utilizes these segues.

If you are Working On Oracle Then:

SELECT column1 || column2 AS column3
FROM table;

OR

If You Are Working On MySql Then:

SELECT Concat(column1 ,column2) AS column3
FROM table;

Here is a more generic solution based on @Arun answer

public abstract class TextViewLinkHandler extends LinkMovementMethod {

    public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {
        if (event.getAction() != MotionEvent.ACTION_UP)
            return super.onTouchEvent(widget, buffer, event);

        int x = (int) event.getX();
        int y = (int) event.getY();

        x -= widget.getTotalPaddingLeft();
        y -= widget.getTotalPaddingTop();

        x += widget.getScrollX();
        y += widget.getScrollY();

        Layout layout = widget.getLayout();
        int line = layout.getLineForVertical(y);
        int off = layout.getOffsetForHorizontal(line, x);

        URLSpan[] link = buffer.getSpans(off, off, URLSpan.class);
        if (link.length != 0) {
            onLinkClick(link[0].getURL());
        }
        return true;
    }

    abstract public void onLinkClick(String url);
}

To use it just implement onLinkClick of TextViewLinkHandler class. For instance:

    textView.setMovementMethod(new TextViewLinkHandler() {
        @Override
        public void onLinkClick(String url) {
            Toast.makeText(textView.getContext(), url, Toast.LENGTH_SHORT).show();
        }
    });

Using JavaScript

 public ActionResult Index()
 {
    return Content("<script>window.location = 'http://www.example.com';</script>");
 }

Note: As @Jeremy Ray Brown said , This is not the best option but you might find useful in some situations.

Hope this helps.

Another alternative for this (older) question:

import datetime
import pytz
import time

pacific=pytz.timezone('US/Pacific')
now=datetime.datetime.now()
# pacific.dst(now).total_seconds() yields 3600 secs. [aka 1 hour]
time.strftime("%-H", time.gmtime(pacific.dst(now).total_seconds()))
'1'

The above is a good way to tell if your current time zone is actually in daylight savings time or not. (It provides an offset of 0 or 1.) Anyway, the real work is being done by time.strftime("%H:%M:%S", time.gmtime(36901)) which does work on the output of gmtime().

>>> time.strftime("%H:%M:%S",time.gmtime(36901))  # secs = 36901
'10:15:01'

And, that's it! (NOTE: Here's a link to format specifiers for time.strftime(). ...)

Yet another way to do this:

shopt -s extglob

selfpath=$0
selfdir=${selfpath%%+([!/])}

while [[ -L "$selfpath" ]];do
  selfpath=$(readlink "$selfpath")
  if [[ ! "$selfpath" =~ ^/ ]];then
    selfpath=${selfdir}${selfpath}
  fi
  selfdir=${selfpath%%+([!/])}
done

echo $selfpath $selfdir

The differences between strong and retain:

• In iOS4, strong is equal to retain
• It means that you own the object and keep it in the heap until don’t point to it anymore
• If you write retain it will automatically work just like strong

The differences between weak and assign:

• A “weak” reference is a reference that you don’t retain and you keep it as long as someone else points to it strongly
• When the object is “deallocated”, the weak pointer is automatically set to nil
• A "assign" property attribute tells the compiler how to synthesize the property’s setter implementation

<a href="<?php echo $_SERVER['DOCUMENT_ROOT'].'/hello.html'; ?>">go with php</a>
    <br />
<a href="/hello.html">go to with html</a>

Try this yourself and find that they are not exactly the same.

$_SERVER['DOCUMENT_ROOT'] renders an actual file path (on my computer running as it's own server, C:/wamp/www/

HTML's / renders the root of the server url, in my case, localhost/

But C:/wamp/www/hello.html and localhost/hello.html are in fact the same file

Run the following:

$ mysql -u root -p      
mysql> GRANT ALL ON *.* to root@'ipaddress' IDENTIFIED BY 'mysql root password';     
mysql> FLUSH PRIVILEGES;     
mysql> exit

Then attempt a connection from the IP address you specified:

mysql -h address-of-remove-server -u root -p   

You should be able to connect.

You should use fgetcsv. Since you cannot import a file as a stream because the csv is a variable, then you should spoof the string as a file by using php://temp or php://memory first:

$fp = fopen("php://temp", 'r+');
fputs($fp, $csvText);
rewind($fp);

Then you will have no problem using fgetcsv:

$csv = [];
while ( ($data = fgetcsv($fp) ) !== FALSE ) {
    $csv[] = $data;
}

$data will be an array of a single csv line (which may include line breaks or commas, etc), as it should be.

Caveat: The memory limit of php://temp can be controlled by appending /maxmemory:NN, where NN is the maximum amount of data to keep in memory before using a temporary file, in bytes. (the default is 2 MB) http://www.php.net/manual/en/wrappers.php.php

Move path\to\anaconda in the PATH above path\to\python

Your second example does not work if you send the argument by reference. Did you mean

void copyVecFast(vec<int> original) // no reference
{

  vector<int> new_;
  new_.swap(original); 
}

That would work, but an easier way is

vector<int> new_(original);

From the documentation of the HttpWebRequest.Timeout property:

A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.

Is it possible that your DNS query is the cause of the timeout?

The essence of object oriented programming is encapsulating logic together with the data it operates on.

Instance methods are the logic, instance fields are the data. Together, they form an object.

public class Foo
{
    private String foo;
    public Foo(String foo){ this.foo = foo; }
    public getFoo(){ return this.foo; }

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

What could possibly be the result of running the above program?

Without an object, there is no instance data, and while the instance methods exist as part of the class definition, they need an object instance to provide data for them.

In theory, an instance method that does not access any instance data could work in a static context, but then there isn't really any reason for it to be an instance method. It's a language design decision to allow it anyway rather than making up an extra rule to forbid it.

SQL Developer will look in the following location in this order for a tnsnames.ora file

1. $HOME/.tnsnames.ora
2. $TNS_ADMIN/tnsnames.ora
3. TNS_ADMIN lookup key in the registry
4. /etc/tnsnames.ora ( non-windows )
5. $ORACLE_HOME/network/admin/tnsnames.ora
6. LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME_KEY
7. LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME

To see which one SQL Developer is using, issue the command show tns in the worksheet

If your tnsnames.ora file is not getting recognized, use the following procedure:

1. Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.

   In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...

   In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.

2. Confirm the os is recognizing this environmental variable

   From the Windows command line: echo %TNS_ADMIN%

   From linux: echo $TNS_ADMIN

3. Restart SQL Developer

4. Now in SQL Developer right click on Connections and select New Connection.... Select TNS as connection type in the drop down box. Your entries from tnsnames.ora should now display here.

<?php
if ( session_id() != "" ) {
    session_start();
}

Basically, you need to check if a session was started before creating another one; ... more reading.

On the other hand, you chose to destroy an existing session before creating another one using session_destroy().

In addition to dumping the ordered list of keys alongside the dictionary, another low-tech solution, which has the advantage of being explicit, is to dump the (ordered) list of key-value pairs ordered_dict.items(); loading is a simple OrderedDict(<list of key-value pairs>). This handles an ordered dictionary despite the fact that JSON does not have this concept (JSON dictionaries have no order).

It is indeed nice to take advantage of the fact that json dumps the OrderedDict in the correct order. However, it is in general unnecessarily heavy and not necessarily meaningful to have to read all JSON dictionaries as an OrderedDict (through the object_pairs_hook argument), so an explicit conversion of only the dictionaries that must be ordered makes sense too.

Add permission to your Manifest file.

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

If you keep your schema discrete then you can scale an application by deploying a given schema to a new DB server. (This assumes you have an application or system which is big enough to have distinct functionality).

An example, consider a system that performs logging. All logging tables and SPs are in the [logging] schema. Logging is a good example because it is rare (if ever) that other functionality in the system would overlap (that is join to) objects in the logging schema.

A hint for using this technique -- have a different connection string for each schema in your application / system. Then you deploy the schema elements to a new server and change your connection string when you need to scale.

Why bother saving the field as readable? Just us AS

SELECT theTimeStamp, FROM_UNIXTIME(theTimeStamp) AS readableDate
               FROM theTable
               WHERE theTable.theField = theValue;

EDIT: Sorry, we store everything in milliseconds not seconds. Fixed it.

There could be several things causing this and it somewhat depends on what you have set up in your database.

First, you could be using a PK in the table that is also an FK to another table making the relationship 1-1. IN this case you may need to do an update rather than an insert. If you really can have only one address record for an order this may be what is happening.

Next you could be using some sort of manual process to determine the id ahead of time. The trouble with those manual processes is that they can create race conditions where two records gab the same last id and increment it by one and then the second one can;t insert.

Third, you query as it is sent to the database may be creating two records. To determine if this is the case, Run Profiler to see exactly what SQL code you are sending and if ti is a select instead of a values clause, then run the select and see if you have due to the joins gotten some records to be duplicated. IN any even when you are creating code on the fly like this the first troubleshooting step is ALWAYS to run Profiler and see if what got sent was what you expected to be sent.

The following code will work for google apiv2:

public void convertAddress() {
    if (address != null && !address.isEmpty()) {
        try {
            List<Address> addressList = geoCoder.getFromLocationName(address, 1);
            if (addressList != null && addressList.size() > 0) {
                double lat = addressList.get(0).getLatitude();
                double lng = addressList.get(0).getLongitude();
            }
        } catch (Exception e) {
            e.printStackTrace();
        } // end catch
    } // end if
} // end convertAddress

Where address is the String (123 Testing Rd City State zip) you want to convert to LatLng.

Disclaimer: The original question was about MySQL. The SQL Server answer is below.

MySQL

In MySQL, the regex syntax is the following:

SELECT * FROM YourTable WHERE (`url` NOT REGEXP '^[-A-Za-z0-9/.]+$') 

Use the REGEXP clause instead of LIKE. The latter is for pattern matching using % and _ wildcards.

SQL Server

Since you made a typo, and you're using SQL Server (not MySQL), you'll have to create a user-defined CLR function to expose regex functionality.

Take a look at this article for more details.

Check your monitor scaling.

My problem turned out to be this:

It turned out to be different DPI-scaling on the primary and secondary monitor. When the secondary monitor was set to 125% (same as the primary monitor) the icons appeared again.

Answer actually provided by User3163 posting on SuperUser.com

All double quotes inside double quotes which suround the string must be changed doubled. As example I had one of json file strings : "delivery": "Standard", In Vba Editor I changed it into """delivery"": ""Standard""," and everythig works correctly. If you have to insert a lot of similar strings, my proposal first, insert them all between "" , then with VBA editor replace " inside into "". If you will do mistake, VBA editor shows this line in red and you will correct this error.

Differentiating between the possible origins of exceptions raised from a compound with statement

Differentiating between exceptions that occur in a with statement is tricky because they can originate in different places. Exceptions can be raised from either of the following places (or functions called therein):

• ContextManager.__init__
• ContextManager.__enter__
• the body of the with
• ContextManager.__exit__

For more details see the documentation about Context Manager Types.

If we want to distinguish between these different cases, just wrapping the with into a try .. except is not sufficient. Consider the following example (using ValueError as an example but of course it could be substituted with any other exception type):

try:
    with ContextManager():
        BLOCK
except ValueError as err:
    print(err)

Here the except will catch exceptions originating in all of the four different places and thus does not allow to distinguish between them. If we move the instantiation of the context manager object outside the with, we can distinguish between __init__ and BLOCK / __enter__ / __exit__:

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        with mgr:
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        # At this point we still cannot distinguish between exceptions raised from
        # __enter__, BLOCK, __exit__ (also BLOCK since we didn't catch ValueError in the body)
        pass

Effectively this just helped with the __init__ part but we can add an extra sentinel variable to check whether the body of the with started to execute (i.e. differentiating between __enter__ and the others):

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        entered_body = False
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        else:
            # At this point we know the exception came either from BLOCK or from __exit__
            pass

The tricky part is to differentiate between exceptions originating from BLOCK and __exit__ because an exception that escapes the body of the with will be passed to __exit__ which can decide how to handle it (see the docs). If however __exit__ raises itself, the original exception will be replaced by the new one. To deal with these cases we can add a general except clause in the body of the with to store any potential exception that would have otherwise escaped unnoticed and compare it with the one caught in the outermost except later on - if they are the same this means the origin was BLOCK or otherwise it was __exit__ (in case __exit__ suppresses the exception by returning a true value the outermost except will simply not be executed).

try:
    mgr = ContextManager()  # __init__ could raise
except ValueError as err:
    print('__init__ raised:', err)
else:
    entered_body = exc_escaped_from_body = False
    try:
        with mgr:
            entered_body = True  # __enter__ did not raise at this point
            try:
                BLOCK
            except TypeError:  # catching another type (which we want to handle here)
                pass
            except Exception as err:  # this exception would normally escape without notice
                # we store this exception to check in the outer `except` clause
                # whether it is the same (otherwise it comes from __exit__)
                exc_escaped_from_body = err
                raise  # re-raise since we didn't intend to handle it, just needed to store it
    except ValueError as err:
        if not entered_body:
            print('__enter__ raised:', err)
        elif err is exc_escaped_from_body:
            print('BLOCK raised:', err)
        else:
            print('__exit__ raised:', err)

Alternative approach using the equivalent form mentioned in PEP 343

PEP 343 -- The "with" Statement specifies an equivalent "non-with" version of the with statement. Here we can readily wrap the various parts with try ... except and thus differentiate between the different potential error sources:

import sys

try:
    mgr = ContextManager()
except ValueError as err:
    print('__init__ raised:', err)
else:
    try:
        value = type(mgr).__enter__(mgr)
    except ValueError as err:
        print('__enter__ raised:', err)
    else:
        exit = type(mgr).__exit__
        exc = True
        try:
            try:
                BLOCK
            except TypeError:
                pass
            except:
                exc = False
                try:
                    exit_val = exit(mgr, *sys.exc_info())
                except ValueError as err:
                    print('__exit__ raised:', err)
                else:
                    if not exit_val:
                        raise
        except ValueError as err:
            print('BLOCK raised:', err)
        finally:
            if exc:
                try:
                    exit(mgr, None, None, None)
                except ValueError as err:
                    print('__exit__ raised:', err)

Usually a simpler approach will do just fine

The need for such special exception handling should be quite rare and normally wrapping the whole with in a try ... except block will be sufficient. Especially if the various error sources are indicated by different (custom) exception types (the context managers need to be designed accordingly) we can readily distinguish between them. For example:

try:
    with ContextManager():
        BLOCK
except InitError:  # raised from __init__
    ...
except AcquireResourceError:  # raised from __enter__
    ...
except ValueError:  # raised from BLOCK
    ...
except ReleaseResourceError:  # raised from __exit__
    ...

Two ways I know of:

export class SomeComponent implements OnInit
{
    public localVar:any;

    ngOnInit(){
        this.http.get(Path).map(res => res.json()).subscribe(res => this.localVar = res);
    }
}

This will assign your result into local variable once information is returned just like in a promise. Then you just do {{ localVar }}

Another Way is to get a observable as a localVariable.

export class SomeComponent
{
    public localVar:any;

    constructor()
    {
        this.localVar = this.http.get(path).map(res => res.json());
    }
}

This way you're exposing a observable at which point you can do in your html is to use AsyncPipe {{ localVar | async }}

Please try it out and let me know if it works. Also, since angular 2 is pretty new, feel free to comment if something is wrong.

Hope it helps

The good option is to use AdminClient as below before starting to produce or consume the messages

private static final int ADMIN_CLIENT_TIMEOUT_MS = 5000;           
 try (AdminClient client = AdminClient.create(properties)) {
            client.listTopics(new ListTopicsOptions().timeoutMs(ADMIN_CLIENT_TIMEOUT_MS)).listings().get();
        } catch (ExecutionException ex) {
            LOG.error("Kafka is not available, timed out after {} ms", ADMIN_CLIENT_TIMEOUT_MS);
            return;
        }

I think button onclick="history.back();" is one way to solve the problem. But it might not work in the following cases.

1. If the page gets refreshed or reloaded.

2. If the user opens the link in a new page.

To overcome these, the following code could be used if you know which page you have to return to. E.g. If you have a no of links on one page and the back button is to be used to return to that page.

<input type="button" onclick="document.location.href='filename';" value="Back" name="button" class="btn">

{
    if(n==1)

    return n*func1(n-1);
}

int func(int no)
{

    String a=""+no;

    String reverse = new StringBuffer(a).reverse().toString();

    if(a.equals(reverse))
    {

        if(!a.contains("0"))
        {
           System.out.println("hey");
            check=true;
            return Integer.parseInt(a);
        }

    }

      //  else
      //  {
    func(no++);
    if(check==true)
    {
        return 0;
    }
       return 0;   
   }
public static void main(String[] args) {
    // TODO code application logic here
    Scanner in=new Scanner(System.in);
    System.out.println("Enter testcase");
   int testcase=in.nextInt(); 
   while(testcase>0)
   {
     int a=in.nextInt();
     PlaindromeNumbers obj=new PlaindromeNumbers();
       System.out.println(obj.func(a));
       testcase--;
   }
}

}

If you already have nodejs installed (check with which nodejs) and don't want to install another package, you can, as root:

update-alternatives --install /usr/bin/node node /usr/bin/nodejs 99

Normalise the data then store as a varchar. Normalising could be tricky.

That should be a one-time hit. Then as a new record comes in, you're comparing it to normalised data. Should be very fast.

All the answers so far don't address the trailing concern:

Is there an efficient method when there are hundreds of revisions after the one to be deleted?

The steps follow, but for reference, let's assume the following history:

[master] -> [hundreds-of-commits-including-merges] -> [C] -> [R] -> [B]

C: commit just following the commit to be removed (clean)

R: The commit to be removed

B: commit just preceding the commit to be removed (base)

Because of the "hundreds of revisions" constraint, I'm assuming the following pre-conditions:

1. there is some embarrassing commit that you wish never existed
2. there are ZERO subsequent commits that actually depend on that embarassing commit (zero conflicts on revert)
3. you don't care that you will be listed as the 'Committer' of the hundreds of intervening commits ('Author' will be preserved)
4. you have never shared the repository
   • or you actually have enough influence over all the people who have ever cloned history with that commit in it to convince them to use your new history
   • and you don't care about rewriting history

This is a pretty restrictive set of constraints, but there is an interesting answer that actually works in this corner case.

Here are the steps:

1. git branch base B
2. git branch remove-me R
3. git branch save
4. git rebase --preserve-merges --onto base remove-me

If there are truly no conflicts, then this should proceed with no further interruptions. If there are conflicts, you can resolve them and rebase --continue or decide to just live with the embarrassment and rebase --abort.

Now you should be on master that no longer has commit R in it. The save branch points to where you were before, in case you want to reconcile.

How you want to arrange everyone else's transfer over to your new history is up to you. You will need to be acquainted with stash, reset --hard, and cherry-pick. And you can delete the base, remove-me, and save branches

By default, Maven doesn't bundle dependencies in the JAR file it builds, and you're not providing them on the classpath when you're trying to execute your JAR file at the command-line. This is why the Java VM can't find the library class files when trying to execute your code.

You could manually specify the libraries on the classpath with the -cp parameter, but that quickly becomes tiresome.

A better solution is to "shade" the library code into your output JAR file. There is a Maven plugin called the maven-shade-plugin to do this. You need to register it in your POM, and it will automatically build an "uber-JAR" containing your classes and the classes for your library code too when you run mvn package.

To simply bundle all required libraries, add the following to your POM:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.2.4</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  ...
</project>

Once this is done, you can rerun the commands you used above:

$ mvn package
$ java -cp target/bil138_4-0.0.1-SNAPSHOT.jar tr.edu.hacettepe.cs.b21127113.bil138_4.App

If you want to do further configuration of the shade plugin in terms of what JARs should be included, specifying a Main-Class for an executable JAR file, and so on, see the "Examples" section on the maven-shade-plugin site.

JavaScript doesn't have a built-in init() function, that is, it's not a part of the language. But it's not uncommon (in a lot of languages) for individual programmers to create their own init() function for initialisation stuff.

A particular init() function may be used to initialise the whole webpage, in which case it would probably be called from document.ready or onload processing, or it may be to initialise a particular type of object, or...well, you name it.

What any given init() does specifically is really up to whatever the person who wrote it needed it to do. Some types of code don't need any initialisation.

function init() {
  // initialisation stuff here
}

// elsewhere in code
init();

Here's some code that avoids getting the count to instantiate an array, but uses an ArrayList instead and just before returning converts the ArrayList to the needed array type.

Note that Supervisor class here implements ISupervisor interface, but in Java you can't cast from object[] (that ArrayList's plain toArray() method returns) to ISupervisor[] (as I think you are able to do in C#), so you have to iterate through all list items and populate the result array.

/**
 * Get Supervisors for given program id
 * @param connection
 * @param programId
 * @return ISupervisor[]
 * @throws SQLException
 */
public static ISupervisor[] getSupervisors(Connection connection, String programId)
  throws SQLException
{
  ArrayList supervisors = new ArrayList();

  PreparedStatement statement = connection.prepareStatement(SQL.GET_SUPERVISORS);
  try {
    statement.setString(SQL.GET_SUPERVISORS_PARAM_PROGRAMID, programId);
    ResultSet resultSet = statement.executeQuery();  

    if (resultSet != null) {
      while (resultSet.next()) {
        Supervisor s = new Supervisor();
        s.setId(resultSet.getInt(SQL.GET_SUPERVISORS_RESULT_ID));
        s.setFirstName(resultSet.getString(SQL.GET_SUPERVISORS_RESULT_FIRSTNAME));
        s.setLastName(resultSet.getString(SQL.GET_SUPERVISORS_RESULT_LASTNAME));
        s.setAssignmentCount(resultSet.getInt(SQL.GET_SUPERVISORS_RESULT_ASSIGNMENT_COUNT));
        s.setAssignment2Count(resultSet.getInt(SQL.GET_SUPERVISORS_RESULT_ASSIGNMENT2_COUNT));
        supervisors.add(s);
      }
      resultSet.close();
    }
  } finally {
    statement.close();
  }

  int count = supervisors.size();
  ISupervisor[] result = new ISupervisor[count];
  for (int i=0; i<count; i++)
    result[i] = (ISupervisor)supervisors.get(i);
  return result;
}

Do you want to remove all items? If so, do the foreach first, then just use Items.Clear() to remove all of them afterwards.

Otherwise, perhaps loop backwards by indexer:

listBox1.BeginUpdate();
try {
  for(int i = listBox1.Items.Count - 1; i >= 0 ; i--) {
    // do with listBox1.Items[i]

    listBox1.Items.RemoveAt(i);
  }
} finally {
  listBox1.EndUpdate();
}

I guess you cant, this maybe a limitation or not included in the IE browser. I have tried your jsfiddle with IE6-8 and all of it doesn't show the scrollbar and not sure with IE9. While in FF and chrome the scrollbar is shown. I also want to see how to do it in IE if possible.

If you really want to show the scrollbar, you can add a fake scrollbar. If you are familiar with some of the js library which use in RIA. Like in jquery/dojo some of the select is editable, because it is a combination of textbox + select or it can also be a textbox + div.

As an example, see it here a JavaScript that make select like editable.

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

ConsoleAppLauncher is an open source library made specifically to answer that question. It captures all the output generated in the console and provides simple interface to start and close console application.

The ConsoleOutput event is fired every time when a new line is written by the console to standard/error output. The lines are queued and guaranteed to follow the output order.

Also available as NuGet package.

Sample call to get full console output:

// Run simplest shell command and return its output.
public static string GetWindowsVersion()
{
    return ConsoleApp.Run("cmd", "/c ver").Output.Trim();
}

Sample with live feedback:

// Run ping.exe asynchronously and return roundtrip times back to the caller in a callback
public static void PingUrl(string url, Action<string> replyHandler)
{
    var regex = new Regex("(time=|Average = )(?<time>.*?ms)", RegexOptions.Compiled);
    var app = new ConsoleApp("ping", url);
    app.ConsoleOutput += (o, args) =>
    {
        var match = regex.Match(args.Line);
        if (match.Success)
        {
            var roundtripTime = match.Groups["time"].Value;
            replyHandler(roundtripTime);
        }
    };
    app.Run();
}

This problem is also caused by:

If you are on a mac/linux, and are using 'ControlMaster' in your ~/.ssh/config, there may be some ssh control master processes running.

To find them, run:

ps aux | grep '\[mux\]'

And kill the relevant ones.

As already noted by manu, XOR algorithm is a popular one which works for all integer values (that includes pointers then, with some luck and casting). For the sake of completeness I would like to mention another less powerful algorithm with addition/subtraction:

A = A + B
B = A - B
A = A - B

Here you have to be careful of overflows/underflows, but otherwise it works just as fine. You might even try this on floats/doubles in the case XOR isn't allowed on those.

Here's the Javadoc in Oracle's website for the Date class: https://docs.oracle.com/javase/8/docs/api/java/util/Date.html
If you scroll down to "Constructor Summary," you'll see the different options for how a Date object can be instantiated. Like all objects in Java, you create a new one with the following:

Date firstDate = new Date(ConstructorArgsHere);

Now you have a bit of a choice. If you don't pass in any arguments, and just do this,

Date firstDate = new Date();

it will represent the exact date and time at which you called it. Here are some other constructors you may want to make use of:

Date firstDate1 = new Date(int year, int month, int date);
Date firstDate2 = new Date(int year, int month, int date, int hrs, int min);
Date firstDate3 = new Date(int year, int month, int date, int hrs, int min, int sec);

Just hide them before showing them:

$(document).ready(function(){ 
    $("input[name$='group2']").click(function() {
        var test = $(this).val();
        $("div.desc").hide();
        $("#"+test).show();
    }); 
});

Also, if you can't change class B, you can fix the error by using multiple inheritance.

class B:
    def meth(self, arg):
        print arg

class C(B, object):
    def meth(self, arg):
        super(C, self).meth(arg)

print C().meth(1)

In order to determine the aspect ratio, you need to have a ratio to aim for.

function getHeight(length, ratio) {
  var height = ((length)/(Math.sqrt((Math.pow(ratio, 2)+1))));
  return Math.round(height);
}

function getWidth(length, ratio) {
  var width = ((length)/(Math.sqrt((1)/(Math.pow(ratio, 2)+1))));
  return Math.round(width);
}

In this example I use 16:10 since this the typical monitor aspect ratio.

var ratio = (16/10);
var height = getHeight(300,ratio);
var width = getWidth(height,ratio);

console.log(height);
console.log(width);

Results from above would be 147 and 300

It seems to me that your Hibernate libraries are not found (NoClassDefFoundError: org/hibernate/boot/archive/scan/spi/ScanEnvironment as you can see above).

Try checking to see if Hibernate core is put in as dependency:

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-core</artifactId>
  <version>5.0.11.Final</version>
  <scope>compile</scope>
</dependency>

var window = new MyWindow();

for center of the screen use:

window.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterScreen;

for center of the parent window use:

window.WindowStartupLocation = System.Windows.WindowStartupLocation.CenterOwner;

ADT are a set of data values and associated operations that are precisely independent of any paticular implementaition. The strength of an ADT is implementaion is hidden from the user.only interface is declared .This means that the ADT is various ways

What you are looking for is probably this:

ImageView myImageView;
myImageView = mDialog.findViewById(R.id.image_id);
String src = "imageFileName"

int drawableId = this.getResources().getIdentifier(src, "drawable", context.getPackageName())
popupImageView.setImageResource(drawableId);

Let me know if this was helpful :)

Instead of invoking the sp_helptext locally with a remote argument, invoke it remotely with a local argument:

EXEC  [ServerName].[DatabaseName].dbo.sp_HelpText 'storedProcName'

== => !=

=== => !==

Equal and its opposite

Sometimes it is not desirable to use interpolation on title attribute or on any other attributes as for that matter, because they get parsed before the interpolation takes place. So:

<!-- dont do this -->
<!-- <a title="{{product.shortDesc}}" ...> -->

If an attribute with a binding is prefixed with the ngAttr prefix (denormalized as ng-attr-) then during the binding will be applied to the corresponding unprefixed attribute. This allows you to bind to attributes that would otherwise be eagerly processed by browsers. The attribute will be set only when the binding is done. The prefix is then removed:

<!-- do this -->
<a ng-attr-title="{{product.shortDesc}}" ...>

(Ensure that you are not using a very earlier version of Angular). Here's a demo fiddle using v1.2.2:

Fiddle

To change database owner:

ALTER AUTHORIZATION ON DATABASE::YourDatabaseName TO sa

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

What about element.tagName?

See also tagName docs on MDN.

If you are using Kotlin then this will solve your problem. (MS Json format)

val dataString = "/Date(1586583441106)/"
val date = Date(Long.parseLong(dataString.substring(6, dataString.length - 2)))

es6

for (let [key, value] of map) {
    console.log(key, value);
}

es5

for (let entry of Array.from(map.entries())) {
    let key = entry[0];
    let value = entry[1];
}

For the first case you propose you can use: '[[:blank:]]+[A-Z0-9]+[[:blank:]]+', for example:

echo "The thing P1 must connect to the J236 thing in the Foo position" | grep -oE '[[:blank:]]+[A-Z0-9]+[[:blank:]]+'

In the second case maybe you need to use something else and not a regex, maybe a script with a dictionary of technical words...

Cheers, Fernando

You can also check for socket output stream error while writing to client socket.

out.println(output);
if(out.checkError())
{
    throw new Exception("Error transmitting data.");
}

Description

You can do this using jQuery's .bind() method. Check out the jsFiddle.

Sample

Html

<input id="myTextBox" type="text"/>

jQuery

$("#myTextBox").bind("change paste keyup", function() {
   alert($(this).val()); 
});

A few others have posted answers. There are some obvious problems, like it returns false when the Regex passes, and the ^ and $ operators indicate start/end, whereas the question is looking for has (any) whitespace, and not: only contains whitespace (which the regex is checking).

Besides that, the issue is just a typo.

Change this...

var reWhiteSpace = new RegExp("/^\s+$/");

To this...

var reWhiteSpace = new RegExp("\\s+");

When using a regex within RegExp(), you must do the two following things...

• Omit starting and ending / brackets.
• Double-escape all sequences code, i.e., \\s in place of \s, etc.

Full working demo from source code....

$(document).ready(function(e) { function hasWhiteSpace(s) {
        var reWhiteSpace = new RegExp("\\s+");
    
        // Check for white space
        if (reWhiteSpace.test(s)) {
            //alert("Please Check Your Fields For Spaces");
            return 'true';
        }
    
        return 'false';
    }
  
  $('#whitespace1').html(hasWhiteSpace(' '));
  $('#whitespace2').html(hasWhiteSpace('123'));
});

You can try to do this:

...
// get completed xml document
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;
$xml_string = $doc->saveXML();
echo $xml_string;

You can make set these parameter right after you've created the DOMDocument as well:

$doc = new DomDocument('1.0');
$doc->preserveWhiteSpace = false;
$doc->formatOutput = true;

That's probably more concise. Output in both cases is (Demo):

<?xml version="1.0"?>
<root>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
  <error>
    <a>eee</a>
    <b>sd</b>
    <c>df</c>
  </error>
</root>

I'm not aware how to change the indentation character(s) with DOMDocument. You could post-process the XML with a line-by-line regular-expression based replacing (e.g. with preg_replace):

$xml_string = preg_replace('/(?:^|\G)  /um', "\t", $xml_string);

Alternatively, there is the tidy extension with tidy_repair_string which can pretty print XML data as well. It's possible to specify indentation levels with it, however tidy will never output tabs.

tidy_repair_string($xml_string, ['input-xml'=> 1, 'indent' => 1, 'wrap' => 0]);

Perfect solution I have tried it and succeed to get my index page when I have append this code in my site configuration file.

location / {
            try_files $uri $uri/ /index.php;
}

In configuration file itself explained that at "First attempt to serve request as file, then as directory, then fall back to index.html in my case it is index.php as I am providing page through php code.

In your package.json, go to scripts and use --port 4000 or set PORT=4000, like in the example below:

package.json (Windows):

"scripts": {
    "start": "set PORT=4000 && react-scripts start"
}

package.json (Ubuntu):

"scripts": {
    "start": "export PORT=4000 && react-scripts start"
}

I needed to run this Zip function in Mac OSX

so I would always zip that annoying .DS_Store.

I adapted https://stackoverflow.com/users/2019515/user2019515 by including additionalIgnore files.

function zipIt($source, $destination, $include_dir = false, $additionalIgnoreFiles = array())
{
    // Ignore "." and ".." folders by default
    $defaultIgnoreFiles = array('.', '..');

    // include more files to ignore
    $ignoreFiles = array_merge($defaultIgnoreFiles, $additionalIgnoreFiles);

    if (!extension_loaded('zip') || !file_exists($source)) {
        return false;
    }

    if (file_exists($destination)) {
        unlink ($destination);
    }

    $zip = new ZipArchive();
        if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
        return false;
        }
    $source = str_replace('\\', '/', realpath($source));

    if (is_dir($source) === true)
    {

        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

        if ($include_dir) {

            $arr = explode("/",$source);
            $maindir = $arr[count($arr)- 1];

            $source = "";
            for ($i=0; $i < count($arr) - 1; $i++) { 
                $source .= '/' . $arr[$i];
            }

            $source = substr($source, 1);

            $zip->addEmptyDir($maindir);

        }

        foreach ($files as $file)
        {
            $file = str_replace('\\', '/', $file);

            // purposely ignore files that are irrelevant
            if( in_array(substr($file, strrpos($file, '/')+1), $ignoreFiles) )
                continue;

            $file = realpath($file);

            if (is_dir($file) === true)
            {
                $zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
            }
            else if (is_file($file) === true)
            {
                $zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
            }
        }
    }
    else if (is_file($source) === true)
    {
        $zip->addFromString(basename($source), file_get_contents($source));
    }

    return $zip->close();
}

SO to ignore the .DS_Store from zip, you run

zipIt('/path/to/folder', '/path/to/compressed.zip', false, array('.DS_Store'));

You can get the milliseconds since 1/1/1970 using such code:

private static DateTime JanFirst1970 = new DateTime(1970, 1, 1);
public static long getTime()
{
    return (long)((DateTime.Now.ToUniversalTime() - JanFirst1970).TotalMilliseconds + 0.5);
}

Fast and good hash functions can be composed from fast permutations with lesser qualities, like

• multiplication with an uneven integer
• binary rotations
• xorshift

To yield a hashing function with superior qualities, like demonstrated with PCG for random number generation.

This is in fact also the recipe rrxmrrxmsx_0 and murmur hash are using, knowingly or unknowingly.

I personally found

uint64_t xorshift(const uint64_t& n,int i){
  return n^(n>>i);
}
uint64_t hash(const uint64_t& n){
  uint64_t p = 0x5555555555555555ull; // pattern of alternating 0 and 1
  uint64_t c = 17316035218449499591ull;// random uneven integer constant; 
  return c*xorshift(p*xorshift(n,32),32);
}

to be good enough.

A good hash function should

1. be bijective to not loose information, if possible and have the least collisions
2. cascade as much and as evenly as possible, i.e. each input bit should flip every output bit with probability 0.5.

Let's first look at the identity function. It satisfies 1. but not 2. :

Input bit n determines output bit n with a correlation of 100% (red) and no others, they are therefore blue, giving a perfect red line across.

A xorshift(n,32) is not much better, yielding one and half a line. Still satisfying 1., because it is invertible with a second application.

A multiplication with an unsigned integer ("Knuth's multiplicative method") is much better, cascading more strongly and flipping more output bits with a probability of 0.5, which is what you want, in green. It satisfies 1. as for each uneven integer there is a multiplicative inverse.

Combining the two gives the following output, still satisfying 1. as the composition of two bijective functions yields another bijective function.

A second application of multiplication and xorshift will yield the following:

Or you can use Galois field multiplications like GHash, they have become reasonably fast on modern CPUs and have superior qualities in one step.

   uint64_t const inline gfmul(const uint64_t& i,const uint64_t& j){           
     __m128i I{};I[0]^=i;

Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec

Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec, as I have ~/bin in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...

Launch it from the root of your project, where you can see src and target dirs.

The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)

$ mvnexec 
 1) org.jmeld.ui.JMeldComponent
 2) org.jmeld.ui.text.FileDocument
 3) org.jmeld.JMeld
 4) org.jmeld.util.UIDefaultsPrint
 5) org.jmeld.util.PrintProperties
 6) org.jmeld.util.file.DirectoryDiff
 7) org.jmeld.util.file.VersionControlDiff
 8) org.jmeld.vc.svn.InfoCmd
 9) org.jmeld.vc.svn.DiffCmd
10) org.jmeld.vc.svn.BlameCmd
11) org.jmeld.vc.svn.LogCmd
12) org.jmeld.vc.svn.CatCmd
13) org.jmeld.vc.svn.StatusCmd
14) org.jmeld.vc.git.StatusCmd
15) org.jmeld.vc.hg.StatusCmd
16) org.jmeld.vc.bzr.StatusCmd
17) org.jmeld.Main
18) org.apache.commons.jrcs.tools.JDiff
#? 

If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P)

By default it compiles project every run. but you can avoid that using mvnexec -B

It allows to search only in test classes -M or --no-main, or only in main classes -T or --no-test. also has a filter by name option -f <whatever>

Hope this could save you some time, for me it does.

Actually I cannot agree to each statement.

"COALESCE expects all arguments to be of same datatype."

This is wrong, see below. Arguments can be different data types, that is also documented: If all occurrences of expr are numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type, then Oracle Database determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that data type, and returns that data type.. Actually this is even in contradiction to common expression "COALESCE stops at first occurrence of a non-Null value", otherwise test case No. 4 should not raise an error.

Also according to test case No. 5 COALESCE does an implicit conversion of arguments.

DECLARE
    int_val INTEGER := 1;
    string_val VARCHAR2(10) := 'foo';

    END;

    DBMS_OUTPUT.PUT_LINE( '5. COALESCE(SYSDATE,SYSTIMESTAMP) -> '|| COALESCE(SYSDATE,SYSTIMESTAMP) );

END;

Output:

2. NVL(string_val, int_val) -> foo
3. COALESCE(int_val,string_val) -> 1

5. COALESCE(SYSDATE,SYSTIMESTAMP) -> 2016-11-30 09:55:55.000000 +1:0 --> This is a TIMESTAMP value, not a DATE value!

try os.path.exists this will check for the path and return True if exists and False if not.

The error is due the fact that you are passing a wrong to strcat(). Look at strcat()'s prototype:

   char *strcat(char *dest, const char *src);

But you pass char as the second argument, which is obviously wrong.

Use snprintf() instead.

char str[1024] = "Hello World";
char tmp = '.';
size_t len = strlen(str);

snprintf(str + len, sizeof str - len, "%c", tmp);

As commented by OP:

That was just a example with Hello World to describe the Problem. It must be empty as first in my real program. Program will fill it later. The problem just contains to add a char/int to an char Array

In that case, snprintf() can handle it easily to "append" integer types to a char buffer too. The advantage of snprintf() is that it's more flexible to concatenate various types of data into a char buffer.

For example to concatenate a string, char and an int:

char str[1024];
ch tmp = '.';
int i = 5;

// Fill str here

snprintf(str + len, sizeof str - len, "%c%d", str, tmp, i);

You don't necessarily have to create a Spring project. Almost all Java web applications have he same project structure. In almost every project I create, I automatically add these source folder:

• src/main/java
• src/main/resources
• src/test/java
• src/test/resources
• src/main/webapp*

src/main/webapp isn't actually a source folder. The web.xml file under src/main/webapp/WEB-INF will allow you to run your java application on any Java enabled web server (Tomcat, Jetty, etc.). I typically add the Jetty Plugin to my POM (assuming you use Maven), and launch the web app in development using mvn clean jetty:run.

Try this

#generic_search_button
{
    float: left;
    width: 24px; /*new width*/
    height: 24px; /*new width*/
    border: none !important; /* no border and override any inline styles*/
    margin-top: 7px;
    cursor: pointer;
    background-color: White;
    background-image: url(/Images/search.png);
    background-repeat: no-repeat;
    background-position: center center;
}

I think the image size might be wrong

Just append :after to your #alertlist li:hover selector the same way you do with your #alertlist li.selected selector:

#alertlist li.selected:after, #alertlist li:hover:after
{
    position:absolute;
    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}

Put the text in an inline element, such as a <span>.

<h1><span>The Last Will and Testament of Eric Jones</span></h1>

And then apply the background color on the inline element.

h1 {
    text-align: center; 
}
h1 span { 
    background-color: green; 
}

An inline element is as big as its contents is, so that should do it for you.

In Stored procedure, you return the values using OUT parameter ONLY. As you have defined two variables in your example:

   outstaticip OUT VARCHAR2, outcount OUT NUMBER

Just assign the return values to the out parameters i.e. outstaticip and outcount and access them back from calling location. What I mean here is: when you call the stored procedure, you will be passing those two variables as well. After the stored procedure call, the variables will be populated with return values.

If you want to have RETURN value as return from the PL/SQL call, then use FUNCTION. Please note that in case, you would be able to return only one variable as return variable.

Well, SEE is expensive. However SQLite has interface built-in for encryption (Pager). This means, that on top of existing code one can easily develop some encryption mechanism, does not have to be AES. Anything really. Please see my post here: https://stackoverflow.com/a/49161716/9418360

You need to define SQLITE_HAS_CODEC=1 to enable Pager encryption. Sample code below (original SQLite source):

#ifdef SQLITE_HAS_CODEC
/*
** This function is called by the wal module when writing page content
** into the log file.
**
** This function returns a pointer to a buffer containing the encrypted
** page content. If a malloc fails, this function may return NULL.
*/
SQLITE_PRIVATE void *sqlite3PagerCodec(PgHdr *pPg){
  void *aData = 0;
  CODEC2(pPg->pPager, pPg->pData, pPg->pgno, 6, return 0, aData);
  return aData;
}
#endif

There is a commercial version in C language for SQLite encryption using AES256 - it can also work with PHP, but it needs to be compiled with PHP and SQLite extension. It de/encrypts SQLite database file on the fly, file contents are always encrypted. Very useful.

According to your requirement

just show me a basic example of using setTimeout to loop something

we have following example which can help you

var itr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];_x000D_
var  interval = 1000; //one second_x000D_
itr.forEach((itr, index) => {_x000D_
_x000D_
  setTimeout(() => {_x000D_
    console.log(itr)_x000D_
  }, index * interval)_x000D_
})

The way to do was looking at the code in code/core/Mage/Catalog/Model/Resource/Category/Flat/Collection.php at line 380 in Magento 1.7.2 on the function setPage($pageNum, $pageSize)

 $collection = Mage::getModel('model')
     ->getCollection()
     ->setCurPage(2) // 2nd page
     ->setPageSize(10); // 10 elements per pages

I hope this will help someone.

I don't think this is possible. There appears to be an open Jira for it:

SPR-6702: Explicitly set response Content-Type in @ResponseBody

This command shows the configured heap sizes in bytes.

java -XX:+PrintFlagsFinal -version | grep HeapSize

It works on Amazon AMI on EC2 as well.

Consider that, when having a large number of files, there is a Limit at INotify Watches on Linux. So increasing the watches limit to 512K, for example, can solve this.

sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p --system

Note that the previous causes an in-memory change that you will lose after restart.

However, you can make it persistent, by executing:

echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

As a reference, you can check: https://github.com/angular/angular-cli/issues/8313#issuecomment-362728855 and https://github.com/guard/listen/wiki/Increasing-the-amount-of-inotify-watchers

Here is an example that should help. If you have a timestamp with a timezone, you can convert that timestamp into any other timezone. If you haven't got a base timezone it won't be converted correctly.

SELECT now(),
   now()::timestamp,
   now() AT TIME ZONE 'CST',
   now()::timestamp AT TIME ZONE 'CST'

Output:

-[ RECORD 1 ]---------------------------
now      | 2018-09-15 17:01:36.399357+03
now      | 2018-09-15 17:01:36.399357

timezone | 2018-09-16 02:01:36.399357+03

If anyone wonders for the Array version, it goes like this:

int i = Array.FindIndex(yourArray, x => x == itemYouWant);

On most platforms, long and int are the same size (32 bits). Still, it does have its own format specifier:

long n;
unsigned long un;
printf("%ld", n); // signed
printf("%lu", un); // unsigned

For 64 bits, you'd want a long long:

long long n;
unsigned long long un;
printf("%lld", n); // signed
printf("%llu", un); // unsigned

Oh, and of course, it's different in Windows:

printf("%l64d", n); // signed
printf("%l64u", un); // unsigned

Frequently, when I'm printing 64-bit values, I find it helpful to print them in hex (usually with numbers that big, they are pointers or bit fields).

unsigned long long n;
printf("0x%016llX", n); // "0x" followed by "0-padded", "16 char wide", "long long", "HEX with 0-9A-F"

will print:

0x00000000DEADBEEF

Btw, "long" doesn't mean that much anymore (on mainstream x64). "int" is the platform default int size, typically 32 bits. "long" is usually the same size. However, they have different portability semantics on older platforms (and modern embedded platforms!). "long long" is a 64-bit number and usually what people meant to use unless they really really knew what they were doing editing a piece of x-platform portable code. Even then, they probably would have used a macro instead to capture the semantic meaning of the type (eg uint64_t).

char c;       // 8 bits
short s;      // 16 bits
int i;        // 32 bits (on modern platforms)
long l;       // 32 bits
long long ll; // 64 bits 

Back in the day, "int" was 16 bits. You'd think it would now be 64 bits, but no, that would have caused insane portability issues. Of course, even this is a simplification of the arcane and history-rich truth. See wiki:Integer

sh files are unix (linux) shell executables files, they are the equivalent (but much more powerful) of bat files on windows.

So you need to run it from a linux console, just typing its name the same you do with bat files on windows.

I had the same issue, it turns that I had my project configured as many of you stated above, yet the problem persisted, so I went deeper and came across that I was using Apache Tomcat 6 as my Runtime Server, so the fix was simple, I just upgraded the project to use Apache Tomcat 7 and that's all, finally the IDE recognized javax.servlet.annotation.WebServlet annotation.

On windows, nearly all AMPP (Apache,MySQL,PHP,PHPmyAdmin) packages don't include a mail server (but nearly all naked linuxes do have!). So, when using PHP under windows, you need to setup a mail server!

Imo the best and most simple tool ist this: http://smtp4dev.codeplex.com/

SMTP4Dev is a simple one-file mail server tool that does collect the mails it send (so it does not really sends mail, it just keeps them for development). Perfect tool.

Edit: Thanks Marc, read up on the struct vs class issue and you're right, thank you!

I tend to use the following method for doing what you describe, using a static method of JSon.Net:

MyObject deserializedObject = JsonConvert.DeserializeObject<MyObject>(json);

Link: Serializing and Deserializing JSON with Json.NET

For the Objects list, may I suggest using generic lists out made out of your own small class containing attributes and position class. You can use the Point struct in System.Drawing (System.Drawing.Point or System.Drawing.PointF for floating point numbers) for you X and Y.

After object creation it's much easier to get the data you're after vs. the text parsing you're otherwise looking at.

If you cannot use spark-csv, you can do the following:

df.rdd.map(lambda x: ",".join(map(str, x))).coalesce(1).saveAsTextFile("file.csv")

If you need to handle strings with linebreaks or comma that will not work. Use this:

import csv
import cStringIO

def row2csv(row):
    buffer = cStringIO.StringIO()
    writer = csv.writer(buffer)
    writer.writerow([str(s).encode("utf-8") for s in row])
    buffer.seek(0)
    return buffer.read().strip()

df.rdd.map(row2csv).coalesce(1).saveAsTextFile("file.csv")

regexp_replace(rndc.pd, '\\s+', '_','g') as pd

You can create an std::string

#include <string>
#include <vector>
int main(int argc, char *argv[])
{
  // check if there is more than one argument and use the second one
  //  (the first argument is the executable)
  if (argc > 1)
  {
    std::string arg1(argv[1]);
    // do stuff with arg1
  }

  // Or, copy all arguments into a container of strings
  std::vector<std::string> allArgs(argv, argv + argc);
}

First off I should point out that css animations would probably work best if you are doing this a lot but I ended getting the desired effect by wrapping .scrollLeft inside .animate

});

$('.swipeLeft').click(function()

    $('.swipeBox').animate( { scrollLeft: '-=460' }, 1000);
});

The second parameter is speed, and you can also add a third parameter if you are using smooth scrolling of some sort.

You need to save your PHP script file in UTF-8 encoding, and leave the <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> in the HTML.

For text editor, I recommend Notepad++, because it can detect and display the actual encoding of the file (in the lower right corner of the editor), and you can convert it as well.

Something like

select *
  from foo
 where regexp_like( col1, '[^[:alpha:]]' ) ;

should work

SQL> create table foo( col1 varchar2(100) );

Table created.

SQL> insert into foo values( 'abc' );

1 row created.

SQL> insert into foo values( 'abc123' );

1 row created.

SQL> insert into foo values( 'def' );

1 row created.

SQL> select *
  2    from foo
  3   where regexp_like( col1, '[^[:alpha:]]' ) ;

COL1
--------------------------------------------------------------------------------
abc123

In my case, I was having the same error using docker and the trick was in setting in the .env file this DB_HOST=db where db is the name of the container running the database server.

Yes there is a difference in the performance of both: jQuery('#id').show() is slower than jQuery('#id').css("display","block") as in former case extra work is to be done for retrieving the initial state from the jquery cache as display is not a binary attribute it can be inline,block,none,table, etc. similar is the case with hide() method.

See: http://jsperf.com/show-vs-addclass

And now something completely different...

Instead of using css tricks don't forget about solutions as simple as html entities:

You can pivot your DataFrame after creating:

>>> df = pd.DataFrame(data)
>>> df.pivot(index=0, columns=1, values=2)
# avg DataFrame
1      c1     c2
0               
r1  avg11  avg12
r2  avg21  avg22
>>> df.pivot(index=0, columns=1, values=3)
# stdev DataFrame
1        c1       c2
0                   
r1  stdev11  stdev12
r2  stdev21  stdev22

As explained above, you can use the Firebase default push id.

If you want something numeric you can do something based on the timestamp to avoid collisions

f.e. something based on date,hour,second,ms, and some random int at the end

01612061353136799031

Which translates to:

016-12-06 13:53:13:679 9031

It all depends on the precision you need (social security numbers do the same with some random characters at the end of the date). Like how many transactions will be expected during the day, hour or second. You may want to lower precision to favor ease of typing.

You can also do a transaction that increments the number id, and on success you will have a unique consecutive number for that user. These can be done on the client or server side.

I always use below approach. I've created one table in database as Table1 with only one column i.e. Row_Id Number (Long Integer) and its value is 0

INSERT INTO <TABLE_NAME_TO_RESET>
SELECT Row_Id AS <COLUMN_NAME_TO_RESET>
FROM Table1;

This will insert one row with 0 value in AutoNumber column, later delete that row.

If you want to make sure that your $ operator does not suffer from XSS hack you can implement ServletContextListener and do some checks there.

Again: This only guards the $. Please also see other answers.

The KeyDown event only triggered at the standard TextBox or MaskedTextBox by "normal" input keys, not ENTER or TAB and so on.

One can get special keys like ENTER by overriding the IsInputKey method:

public class CustomTextBox : System.Windows.Forms.TextBox
{
    protected override bool IsInputKey(Keys keyData)
    {
        if (keyData == Keys.Return)
            return true;
        return base.IsInputKey(keyData);
    }
}

Then one can use the KeyDown event in the following way:

CustomTextBox ctb = new CustomTextBox();
ctb.KeyDown += new KeyEventHandler(tb_KeyDown);

private void tb_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
          //Enter key is down

          //Capture the text
          if (sender is TextBox)
          {
              TextBox txb = (TextBox)sender;
              MessageBox.Show(txb.Text);
          }
    }
}

Google Reflection if you want to discover interfaces as well.

Spring ClassPathScanningCandidateComponentProvider is not discovering interfaces.

You can use Visual Studio for C, but if you are serious about learning the newest C available, I recommend using something like Code::Blocks with MinGW-TDM version, which you can get a 32 bit version of. I use version 5.1 which supports the newest C and C++. Another benefit is that it is a better platform for creating software that can be easily ported to other platforms. If you were, for example, to code in C, using the SDL library, you could create software that could be recompiled with little to no changes to the code, on Linux, Apple and many mobile devices. The way Microsoft has been going these days, I think this is definitely the better route to take.

Question: Is there a simple way to do this in the current release of Python?

Answer: There is no simple (direct) way to do this in the current release of Python.

Reference: Please refer to docs.python.org/2/library/datetime.html, section 8.1.2. timedelta Objects. As we may understand from that, we cannot increment month directly since it is not a uniform time unit.

Plus: If you want first day -> first day and last day -> last day mapping you should handle that separately for different months.

    python 3.2

    with open("d://test.txt") as f:
              k=(((i.split("\n"))[0].rstrip()).split() for i in f.readlines())
              d={}
              for i,_,v in k:
                      d.setdefault(i,[]).append(v)

For me it was for removing some credentials from a repo. I tried rebasing and ran into a ton of seemingly unrelated conflicts along the way when trying to rebase --continue. Don't bother attempting to rebase yourself, use the tool called BFG (brew install bfg) on mac.

It's not clear exactly what you want to do with the index of a substring [update: it is clearer now - thanks] but you may be able to use the function substring-after or substring-before:

substring-before('My name is Fred', 'Fred')

returns 'My name is '.

If you need more detailed control, the substring() function can take two or three arguments: string, starting-index, length. Omit length to get the whole rest of the string.

There is no index-of() function for strings in XPath (only for sequences, in XPath 2.0). You can use string-length(substring-before($string, $substring))+1 if you specifically need the position.

There is also contains($string, $substring). These are all documented here. In XPath 2.0 you can use regular expression matching.

(XSLT mostly uses XPath for selecting nodes and processing values, so this is actually more of an XPath question. I tagged it thus.)

If I really had to switch on type of object, I'd use .ToString(). However, I would avoid it at all costs: IDictionary<Type, int> will do much better, visitor might be an overkill but otherwise it is still a perfectly fine solution.

 $('image').animate({ 'zoom': 1}, 400);

I'd consider also Apache Thrift http://thrift.apache.org/

It can bridge between several programming languages, is highly efficient and has support for async or sync calls. See full features here http://thrift.apache.org/docs/features/

The multi language can be useful for future plans, for example if you later want to do part of the computational task in C++ it's very easy to do add it to the mix using Thrift.

<div style='width:200px;margin:0 auto;> sometext or image tag</div>

this works horizontally

In C, you can "simulate" exceptions along with automatic "object reclamation" through manual use of if + goto for explicit error handling.

I often write C code like the following (boiled down to highlight error handling):

#include <assert.h>

typedef int errcode;

errcode init_or_fail( foo *f, goo *g, poo *p, loo *l )
{
    errcode ret = 0;

    if ( ( ret = foo_init( f ) ) )
        goto FAIL;

    if ( ( ret = goo_init( g ) ) )
        goto FAIL_F;

    if ( ( ret = poo_init( p ) ) )
        goto FAIL_G;

    if ( ( ret = loo_init( l ) ) )
        goto FAIL_P;

    assert( 0 == ret );
    goto END;

    /* error handling and return */

    /* Note that we finalize in opposite order of initialization because we are unwinding a *STACK* of initialized objects */

FAIL_P:
    poo_fini( p );

FAIL_G:
    goo_fini( g );

FAIL_F:
    foo_fini( f );

FAIL:
    assert( 0 != ret );

END:
    return ret;        
}

This is completely standard ANSI C, separates the error handling away from your mainline code, allows for (manual) stack unwinding of initialized objects much like C++ does, and it is completely obvious what is happening here. Because you are explicitly testing for failure at each point it does make it easier to insert specific logging or error handling at each place an error can occur.

If you don't mind a little macro magic, then you can make this more concise while doing other things like logging errors with stack traces. For example:

#include <assert.h>
#include <stdio.h>
#include <string.h>

#define TRY( X, LABEL ) do { if ( ( X ) ) { fprintf( stderr, "%s:%d: Statement '" #X "' failed! %d, %s\n", __FILE__, __LINE__, ret, strerror( ret ) ); goto LABEL; } while ( 0 )

typedef int errcode;

errcode init_or_fail( foo *f, goo *g, poo *p, loo *l )
{
    errcode ret = 0;

    TRY( ret = foo_init( f ), FAIL );
    TRY( ret = goo_init( g ), FAIL_F );
    TRY( ret = poo_init( p ), FAIL_G );
    TRY( ret = loo_init( l ), FAIL_P );

    assert( 0 == ret );
    goto END;

    /* error handling and return */

FAIL_P:
    poo_fini( p );

FAIL_G:
    goo_fini( g );

FAIL_F:
    foo_fini( f );

FAIL:
    assert( 0 != ret );

END:
    return ret;        
}

Of course, this isn't as elegant as C++ exceptions + destructors. For example, nesting multiple error handling stacks within one function this way isn't very clean. Instead, you'd probably want to break those out into self contained sub functions that similarly handle errors, initialize + finalize explicitly like this.

This also only works within a single function and won't keep jumping up the stack unless higher level callers implement similar explicit error handling logic, whereas a C++ exception will just keep jumping up the stack until it finds an appropriate handler. Nor does it allow you to throw an arbitrary type, but instead only an error code.

Systematically coding this way (i.e. - with a single entry and single exit point) also makes it very easy to insert pre and post ("finally") logic that will execute no matter what. You just put your "finally" logic after the END label.

Here is how to clear all trash & caches (without other private data in browsers) by a command line. This is a command line batch script that takes care of all trash (as of April 2014):

erase "%TMP%\*.*" /f /s /q
for /D %%i in ("%TMP%\*") do RD /S /Q "%%i"

for /D %%i in ("%ALLUSERSPROFILE%\TEMP\*") do RD /S /Q "%%i"

erase "%SystemRoot%\TEMP\*.*" /f /s /q
for /D %%i in ("%SystemRoot%\TEMP\*") do RD /S /Q "%%i"

There are two ways to handle the situation where we do not want the index to be stored in csv file.

1. As others have stated you can use index=False while saving your
   dataframe to csv file.

   df.to_csv('file_name.csv',index=False)

2. Or you can save your dataframe as it is with an index, and while reading you just drop the column unnamed 0 containing your previous index.Simple!

   df.to_csv(' file_name.csv ')
df_new = pd.read_csv('file_name.csv').drop(['unnamed 0'],axis=1)

I ran into this problem although mine is slightly different. Posting here to maybe help somebody sometime.

I had

const Layout = ({ children }) => {
    <div className="mx-4 my-3">
        <Header />
        <Menu />
        {children}
        <Footer />
    </div>
};

But it needed to be:

const Layout = ({ children }) => (
    <div className="mx-4 my-3">
      <Header />
      <Menu />
      {children}
      <Footer />
    </div>
);

It's a difference of tabs vs spaces, I guess. I'm not sure why it'd care...

I have read that while the underlying chips are essentially the same, the design of the board is different.

Gamers want performance, and tend to favor overclocking and other things to get high frame rates but which maybe burn out the hardware occasionally.

Businesses want reliability, and tend to favor underclocking so they can be sure that their people can keep working.

Also, I have read that the quadro boards use ECC memory.

If you don't know what ECC memory is about: it's a [relatively] well known fact that sometimes memory "flips bits (experiences errors)". This does not happen too often, but is an unavoidable consequence of the underlying physics of the memory cards and the world we live in. ECC memory adds a small percentage to the cost and a small penalty to the performance and has enough redundancy to correct occasional errors and to detect (but not correct) somewhat rarer errors. Gamers don't care about that kind of accuracy because for gamers those are just very rare visual glitches. Companies do care about that kind of accuracy because those glitches would wind up as glitches in their products or else would require more double or triple checking (which winds up being a 2x or 3x performance penalty for some part of their business).

Another issue I have read about has to do with hooking up the graphics card to third party hardware. In other words: sending the images to another card or to another machine instead of to the screen. Most gamers are just using canned software that doesn't have any use for such capabilities. Companies that use that kind of thing get orders of magnitude performance gains from the more direct connections.

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is)

        double toLat = 50.45, toLon = 30.523333;
        String url = RoadProvider.getUrl(fromLat, fromLon, toLat, toLon);
        InputStream is = getConnection(url);
        mRoad = RoadProvider.getRoute(is);
        map = new MapControl();
        add(new LabelField(mRoad.mName));
        add(new LabelField(mRoad.mDescription));
        add(map);
    }

        super.onUiEngineAttached(attached);
        if (attached) {
            map.drawPath(mRoad);
        }
    }
    private InputStream getConnection(String url) {
        HttpConnection urlConnection = null;
        InputStream is = null;
        try {
            urlConnection = (HttpConnection) Connector.open(url);
            urlConnection.setRequestMethod("GET");
            is = urlConnection.openInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return is;
    }
}

file() is not supported in Python 3

Use open() instead; see Built-in Functions - open().

Try =index(ARRAY, ROW, COLUMN)

where: Array: select the whole sheet Row, Column: Your row and column references

That should be easier to understand to those looking at the formula.

var formData = new FormData($('#form-id'));
params   = $('#form-id').serializeArray();

$.each(params, function(i, val) {
    formData.append(val.name, val.value);
});

This helped for me:

All you need to do, is to specify a envirnoment variable called JAVA_TOOL_OPTIONS. If you set this variable to -Dfile.encoding=UTF8, everytime a JVM is started, it will pick up this information.

When you use string literals, such as "this is a string" and in your case "sssss" and "kkkk", the compiler puts them in read-only memory. However, strcat attempts to write the second argument after the first. You can solve this problem by making a sufficiently sized destination buffer and write to that.

char destination[10]; // 5 times s, 4 times k, one zero-terminator
char* str1;
char* str2;
str1 = "sssss";
str2 = "kkkk";
strcpy(destination, str1);
printf("%s",strcat(destination,str2));

Note that in recent compilers, you usually get a warning for casting string literals to non-const character pointers.

I believe you can only add variables to the Watch window while the debugger is stopped on a breakpoint. If you set a breakpoint on a step, you should be able to enter variables into the Watch window when the breakpoint is hit. You can select the first empty row in the Watch window and enter the variable name (you may or may not get some Intellisense there, I can't remember how well that works.)

VMDK is a virtual disk file, what you need is a VMX file. Cruise on over to EasyVMX and have it create one for you, then just replace the VMDK file it gives you with the Cnrome OS one.

EasyVMX is good since VMWare Player has no VM creation stuff in it (at least in version 2, not sure about 3). You had to use one of VMWare's other products to do that.

How abt something like this, using the standard bitset ...

#include <bitset> 
#include <iostream> 

template <std::size_t N> 
inline void 
rotate(std::bitset<N>& b, unsigned m) 
{ 
   b = b << m | b >> (N-m); 
} 

int main() 
{ 
   std::bitset<8> b(15); 
   std::cout << b << '\n'; 
   rotate(b, 2); 
   std::cout << b << '\n'; 

   return 0;
}

HTH,

Besides what other said, a common problem is to declare the types of the same function that is overloaded. Typical case is EventEmitter on() method which will accept multiple kind of listeners. Similar could happen When working with redux actions - and there you use the action type as literal to mark the overloading, In case of EventEmitters, you use the event name literal type:

interface MyEmitter extends EventEmitter {
  on(name:'click', l: ClickListener):void
  on(name:'move', l: MoveListener):void
  on(name:'die', l: DieListener):void
  //and a generic one
  on(name:string, l:(...a:any[])=>any):void
}

type ClickListener = (e:ClickEvent)=>void
type MoveListener = (e:MoveEvent)=>void
... etc

// will type check the correct listener when writing something like:
myEmitter.on('click', e=>...<--- autocompletion

Actually, curl has an option explicitly for this: --resolve

Instead of curl -H 'Host: yada.com' http://127.0.0.1/something

use curl --resolve 'yada.com:80:127.0.0.1' http://yada.com/something

What's the difference, you ask?

Among others, this works with HTTPS. Assuming your local server has a certificate for yada.com, the first example above will fail because the yada.com certificate doesn't match the 127.0.0.1 hostname in the URL.

The second example works correctly with HTTPS.

In essence, passing a "Host" header via -H does hack your Host into the header set, but bypasses all of curl's host-specific intelligence. Using --resolve leverages all of the normal logic that applies, but simply pretends the DNS lookup returned the data in your command-line option. It works just like /etc/hosts should.

Note --resolve takes a port number, so for HTTPS you would use

curl --resolve 'yada.com:443:127.0.0.1' https://yada.com/something

You'll need to open the workbook to refer to it.

Sub Setwbk()

    Dim wbk As Workbook

    Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _
        Master Benchmark Data Sheet.xlsx")

End Sub

_{* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:}

Why do I have to "set" it?

Set is how VBA assigns object variables. Since a Range and a Workbook/Worksheet are objects, you must use Set with these.

You can use this working script:

/**
* @param {range} countRange Range to be evaluated
* @param {range} colorRef Cell with background color to be searched for in countRange
* @return {number}
* @customfunction
*/

function countColoredCells(countRange,colorRef) {
  var activeRange = SpreadsheetApp.getActiveRange();
  var activeSheet = activeRange.getSheet();
  var formula = activeRange.getFormula();

  var rangeA1Notation = formula.match(/\((.*)\,/).pop();
  var range = activeSheet.getRange(rangeA1Notation);
  var bg = range.getBackgrounds();
  var values = range.getValues();

  var colorCellA1Notation = formula.match(/\,(.*)\)/).pop();
  var colorCell = activeSheet.getRange(colorCellA1Notation);
  var color = colorCell.getBackground();

  var count = 0;

  for(var i=0;i<bg.length;i++)
    for(var j=0;j<bg[0].length;j++)
      if( bg[i][j] == color )
        count=count+1;
  return count;
};

Then call this function in your google sheets:

=countColoredCells(D5:D123,Z11)

All you have to do is read the code on getbootstrap.com:

default_data['item3'] = 3

Easy as py.

Another possible solution:

default_data.update({'item3': 3})

which is nice if you want to insert multiple items at once.

Most elegant and clean is a jQuery plugin: https://github.com/untill/jquery.longclick/, also available as packacke: https://www.npmjs.com/package/jquery.longclick.

In short, you use it like so:

$( 'button').mayTriggerLongClicks().on( 'longClick', function() { your code here } );

The advantage of this plugin is that, in contrast to some of the other answers here, click events are still possible. Note also that a long click occurs, just like a long tap on a device, before mouseup. So, that's a feature.

If you just want to limit the find to the first level you can do:

 find /dev -maxdepth 1 -name 'abc-*'

... or if you particularly want to exclude the .udev directory, you can do:

 find /dev -name '.udev' -prune -o -name 'abc-*' -print

Try 4.0/100

I prefer minecart as it is extremely easy to use. The below snippet show how to extract images from a pdf:

#pip install minecart
import minecart

pdffile = open('Invoices.pdf', 'rb')
doc = minecart.Document(pdffile)

page = doc.get_page(0) # getting a single page

#iterating through all pages
for page in doc.iter_pages():
    im = page.images[0].as_pil()  # requires pillow
    display(im)

Well that's pretty easy actually with GCD. A typical workflow would be something like this:

dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0ul);
    dispatch_async(queue, ^{
        // Perform async operation
        // Call your method/function here
        // Example:
        // NSString *result = [anObject calculateSomething];
                dispatch_sync(dispatch_get_main_queue(), ^{
                    // Update UI
                    // Example:
                    // self.myLabel.text = result;
                });
    });

For more on GCD you can take a look into Apple's documentation here

1) if list1 is a member of a class, create the list in the constructor so it's there and non-null though empty.

2) for (Object obj : list1 != null ? list1 : new ArrayList())

I've had a similar issue with User registration today and I was getting a

SQLSTATE[HY000]: General error: 1364 Field 'password' doesn't have a default value (SQL: insert into users

I fixed it by adding password to my protected $fillable array and it worked

protected $fillable = [
  'name',
  'email',
  'password',
];

I hope this helps.

String[] strings = new String[25000];
for (int i = 0; i < 25000; i++) strings[i] = '1234567';

String result;
result = "";
for (String s : strings) result += s;
//linear +: 5s

result = "";
for (String s : strings) result = result.concat(s);
//linear .concat: 2.5s

result = String.join("", strings);
//Java 8 .join: 3ms

Public String join(String delimiter, String[] s)
{
    int ls = s.length;
    switch (ls)
    {
        case 0: return "";
        case 1: return s[0];
        case 2: return s[0].concat(delimiter).concat(s[1]);
        default:
            int l1 = ls / 2;
            String[] s1 = Arrays.copyOfRange(s, 0, l1); 
            String[] s2 = Arrays.copyOfRange(s, l1, ls); 
            return join(delimiter, s1).concat(delimiter).concat(join(delimiter, s2));
    }
}
result = join("", strings);
// Divide&Conquer join: 7ms

If you don't have the choise but to use Java 6 or 7 then you should use Divide&Conquer join.

Here is a very simple way to create a custom dialog.

dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">
<!--  Put your layout content  -->
</LinearLayout>

MainActivity.java

ShowPopup(){
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.dialog, null);
android.app.AlertDialog.Builder alertDialogBuilder = new 
android.app.AlertDialog.Builder(this);
alertDialogBuilder.setView(promptsView);
alertDialogBuilder.setCancelable(true);
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}

You can just specify the python version when running a program:

for python 2:

python filename.py

for python 3:

python3 filename.py

Stop this error you have to follow this simple steps

1. Open Visual Studio
2. Select option debug from the top
3. Select Options
4. In Option Select debugging under debugging select General
5. In General Select check box "Automatically close the console when debugging stop"
6. Save it

Then Run the code by using Shortcut key Ctrl+f5

**Other wise it still show error when you run it direct

In my case I changed this:

<mat-form-field>
  <input type="email" placeholder="email" [(ngModel)]="data.email">
</mat-form-field>

to this:

<mat-form-field>
  <input matInput type="email" placeholder="email" [(ngModel)]="data.email">
</mat-form-field>

Adding the matInput directive to the input tag was what fixed this error for me.
