I found a C preprocessor trick that is doing the same job without declaring a dedicated array string (Source: http://userpage.fu-berlin.de/~ram/pub/pub_jf47ht81Ht/c_preprocessor_applications_en).

Sequential enums

Following the invention of Stefan Ram, sequential enums (without explicitely stating the index, e.g. enum {foo=-1, foo1 = 1}) can be realized like this genius trick:

#include <stdio.h>

#define NAMES C(RED)C(GREEN)C(BLUE)
#define C(x) x,
enum color { NAMES TOP };
#undef C

#define C(x) #x,    
const char * const color_name[] = { NAMES };

This gives the following result:

int main( void )  { 
    printf( "The color is %s.\n", color_name[ RED ]);  
    printf( "There are %d colors.\n", TOP ); 
}

The color is RED.
There are 3 colors.

Non-Sequential enums

Since I wanted to map error codes definitions to are array string, so that I can append the raw error definition to the error code (e.g. "The error is 3 (LC_FT_DEVICE_NOT_OPENED)."), I extended the code in that way that you can easily determine the required index for the respective enum values:

#define LOOPN(n,a) LOOP##n(a)
#define LOOPF ,
#define LOOP2(a) a LOOPF a LOOPF
#define LOOP3(a) a LOOPF a LOOPF a LOOPF
#define LOOP4(a) a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP5(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP6(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP7(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP8(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP9(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF


#define LC_ERRORS_NAMES \
    Cn(LC_RESPONSE_PLUGIN_OK, -10) \
    Cw(8) \
    Cn(LC_RESPONSE_GENERIC_ERROR, -1) \
    Cn(LC_FT_OK, 0) \
    Ci(LC_FT_INVALID_HANDLE) \
    Ci(LC_FT_DEVICE_NOT_FOUND) \
    Ci(LC_FT_DEVICE_NOT_OPENED) \
    Ci(LC_FT_IO_ERROR) \
    Ci(LC_FT_INSUFFICIENT_RESOURCES) \
    Ci(LC_FT_INVALID_PARAMETER) \
    Ci(LC_FT_INVALID_BAUD_RATE) \
    Ci(LC_FT_DEVICE_NOT_OPENED_FOR_ERASE) \
    Ci(LC_FT_DEVICE_NOT_OPENED_FOR_WRITE) \
    Ci(LC_FT_FAILED_TO_WRITE_DEVICE) \
    Ci(LC_FT_EEPROM_READ_FAILED) \
    Ci(LC_FT_EEPROM_WRITE_FAILED) \
    Ci(LC_FT_EEPROM_ERASE_FAILED) \
    Ci(LC_FT_EEPROM_NOT_PRESENT) \
    Ci(LC_FT_EEPROM_NOT_PROGRAMMED) \
    Ci(LC_FT_INVALID_ARGS) \
    Ci(LC_FT_NOT_SUPPORTED) \
    Ci(LC_FT_OTHER_ERROR) \
    Ci(LC_FT_DEVICE_LIST_NOT_READY)


#define Cn(x,y) x=y,
#define Ci(x) x,
#define Cw(x)
enum LC_errors { LC_ERRORS_NAMES TOP };
#undef Cn
#undef Ci
#undef Cw
#define Cn(x,y) #x,
#define Ci(x) #x,
#define Cw(x) LOOPN(x,"")
static const char* __LC_errors__strings[] = { LC_ERRORS_NAMES };
static const char** LC_errors__strings = &__LC_errors__strings[10];

In this example, the C preprocessor will generate the following code:

enum LC_errors { LC_RESPONSE_PLUGIN_OK=-10,  LC_RESPONSE_GENERIC_ERROR=-1, LC_FT_OK=0, LC_FT_INVALID_HANDLE, LC_FT_DEVICE_NOT_FOUND, LC_FT_DEVICE_NOT_OPENED, LC_FT_IO_ERROR, LC_FT_INSUFFICIENT_RESOURCES, LC_FT_INVALID_PARAMETER, LC_FT_INVALID_BAUD_RATE, LC_FT_DEVICE_NOT_OPENED_FOR_ERASE, LC_FT_DEVICE_NOT_OPENED_FOR_WRITE, LC_FT_FAILED_TO_WRITE_DEVICE, LC_FT_EEPROM_READ_FAILED, LC_FT_EEPROM_WRITE_FAILED, LC_FT_EEPROM_ERASE_FAILED, LC_FT_EEPROM_NOT_PRESENT, LC_FT_EEPROM_NOT_PROGRAMMED, LC_FT_INVALID_ARGS, LC_FT_NOT_SUPPORTED, LC_FT_OTHER_ERROR, LC_FT_DEVICE_LIST_NOT_READY, TOP };

static const char* __LC_errors__strings[] = { "LC_RESPONSE_PLUGIN_OK", "" , "" , "" , "" , "" , "" , "" , "" "LC_RESPONSE_GENERIC_ERROR", "LC_FT_OK", "LC_FT_INVALID_HANDLE", "LC_FT_DEVICE_NOT_FOUND", "LC_FT_DEVICE_NOT_OPENED", "LC_FT_IO_ERROR", "LC_FT_INSUFFICIENT_RESOURCES", "LC_FT_INVALID_PARAMETER", "LC_FT_INVALID_BAUD_RATE", "LC_FT_DEVICE_NOT_OPENED_FOR_ERASE", "LC_FT_DEVICE_NOT_OPENED_FOR_WRITE", "LC_FT_FAILED_TO_WRITE_DEVICE", "LC_FT_EEPROM_READ_FAILED", "LC_FT_EEPROM_WRITE_FAILED", "LC_FT_EEPROM_ERASE_FAILED", "LC_FT_EEPROM_NOT_PRESENT", "LC_FT_EEPROM_NOT_PROGRAMMED", "LC_FT_INVALID_ARGS", "LC_FT_NOT_SUPPORTED", "LC_FT_OTHER_ERROR", "LC_FT_DEVICE_LIST_NOT_READY", };

This results to the following implementation capabilities:

LC_errors__strings[-1] ==> LC_errors__strings[LC_RESPONSE_GENERIC_ERROR] ==> "LC_RESPONSE_GENERIC_ERROR"

You can't do this without some browser specific code, since they implement text select ranged slightly differently. However, there are plugins that abstract this away. For exactly what you're after, there's the jQuery Caret (jCaret) plugin.

For your code to get the position you could do something like this:

$("#myTextInput").bind("keydown keypress mousemove", function() {
  alert("Current position: " + $(this).caret().start);
});

You can test it here.

You can also use info files to list all the sections of all the binaries loaded in process binary.

You could also use numpy. When your data is stored in a numpy.ndarray:

import numpy as np
from random import sample
l = 100 #length of data 
f = 50  #number of elements you need
indices = sample(range(l),f)

train_data = data[indices]
test_data = np.delete(data,indices)

You should try to remove unnecessary images before removing the image:

docker rmi $(docker images --filter "dangling=true" -q --no-trunc)

After that, run:

docker rmi c565603bc87f

A return value of the previously executed process.

10.4 Getting the return value of a program

In bash, the return value of a program is stored in a special variable called $?.

This illustrates how to capture the return value of a program, I assume that the directory dada does not exist. (This was also suggested by mike)

        #!/bin/bash
        cd /dada &> /dev/null
        echo rv: $?
        cd $(pwd) &> /dev/null
        echo rv: $?

See Bash Programming Manual for more details.

I suggest use instead:

$sudo service mongodb stop

That could work.

That is not what the error message says. It says that you cannot use the = operator. Try for instance LIKE 'foo'.

Apache commons lang now supports this. Just make sure you have a recent enough version of Apache commons lang on your classpath. You'll need version 3.2+

Release Notes for version 3.2

LANG-797: Added escape/unescapeJson to StringEscapeUtils.

To check whether a property exists on a JObject, you can use the square bracket syntax and see whether the result is null or not. If the property exists, a JToken will be always be returned (even if it has the value null in the JSON).

JToken token = jObject["param"];
if (token != null)
{
    // the "param" property exists
}

If you have a JToken in hand and you want to see if it is non-empty, well, that depends on what type of JToken it is and how you define "empty". I usually use an extension method like this:

public static class JsonExtensions
{
    public static bool IsNullOrEmpty(this JToken token)
    {
        return (token == null) ||
               (token.Type == JTokenType.Array && !token.HasValues) ||
               (token.Type == JTokenType.Object && !token.HasValues) ||
               (token.Type == JTokenType.String && token.ToString() == String.Empty) ||
               (token.Type == JTokenType.Null);
    }
}

After carefully going through the thread here and checking all the solutions proposed by people, I can confidently claim this, after following the steps mentioned on Apple developer docs for creating CSR and mobile provision file, just do this!,

1. Launch Xcode.
2. Select window->Organizer
3. Click this refresh button and that filthy yellow bar will remove instantly.

http://img.skitch.com/20100820-1ngm8an14c6fm3dt7g6j51d2nx.jpg

Trust me, you only have to do this. There is no need to repeat the process again and again to make sure that you doing it the right way. Just press Refresh, enter your login credentials and it's done.

Remove the content of the folder \.m2\repository\org\apache\maven\plugins\maven-resource-plugin\2.7. The cached info turned out to be the issue.

Please make sure You are not placing your View or JSP or HTML in WEB-INF or META-INF

I haven't tried it but if you put a div in your table cell set so that it will have scrollbars if needed, then you could insert in there, with a fixed height on the div and it should keep your table row to a fixed height.

Changing keystore password

$ keytool -storepasswd -keystore keystorename
Enter keystore password:  <old password>
New keystore password: <new password>
Re-enter new keystore password: <new password>

Changing keystore alias password

$keytool -keypasswd -keystore keystorename -alias aliasname
Enter keystore password:  
New key password for <aliasname>: 
Re-enter new key password for <aliasname>:

Note:

**Keystorename**: name of your keystore(with path if you are indifferent folder) 
**aliasname**: alias name you used when creating (if name has space you can use \) 
for example: $keytool -keypasswd -keystore keystorename -alias stop\ watch

$myarray = array(
  'test1' => 'foo',
  'test2' => 'bar',
  'test3' => 'baz',
  'test4' => 'waldo'
);

$myarray2 = array(
'foo',
'bar',
'baz',
'waldo'
);

// Get the last array_key
$last = array_pop(array_keys($myarray));
foreach($myarray as $key => $value) {
  if($key != $last) {
    echo "$key -> $value\n";
  }
}

// Get the last array_key
$last = array_pop(array_keys($myarray2));
foreach($myarray2 as $key => $value) {
  if($key != $last) {
    echo "$key -> $value\n";
  }
}

Since array_pop works on the temporary array created by array_keys it doesn't modify the original array at all.

$ php test.php
test1 -> foo
test2 -> bar
test3 -> baz
0 -> foo
1 -> bar
2 -> baz

To get the maximum value of a column across a set of rows:

SELECT MAX(column1) FROM table; -- expect one result

To get the maximum value of a set of columns, literals, or variables for each row:

SELECT GREATEST(column1, 1, 0, @val) FROM table; -- expect many results

How about just doing some linq queries against your dictionary, and then binding your graph to the results of those?...

var under = colStates.Where(c => (decimal)c.Value / (decimal)totalCount < .05M);
var over = colStates.Where(c => (decimal)c.Value / (decimal)totalCount >= .05M);
var newColStates = over.Union(new Dictionary<string, int>() { { "Other", under.Sum(c => c.Value) } });

foreach (var item in newColStates)
{
    Console.WriteLine("{0}:{1}", item.Key, item.Value);
}

I suggest Junidecode . It will handle not only 'L' and 'Ø', but it also works well for transcribing from other alphabets, such as Chinese, into Latin alphabet.

Its better to access the count with the laravels count method

$count = Model::where('status','=','1')->count();

or

$count = Model::count();

Here is the example:

var charCode = "a".charCodeAt(0);_x000D_
console.log(charCode);

Or if you have longer strings:

var string = "Some string";_x000D_
_x000D_
for (var i = 0; i < string.length; i++) {_x000D_
  console.log(string.charCodeAt(i));_x000D_
}

String.charCodeAt(x) method will return ASCII character code at a given position.

You probably want an extra wrapper. use a div for the background and position it below your content..

http://jsfiddle.net/pixelass/42F2j/

HTML

<div id="background-image"></div>
<div id="content">
    Here is the content at opacity 1
    <img src="http://lorempixel.com/100/50/fashion/1/">

</div>

CSS

#background-image {
    background-image: url(http://lorempixel.com/400/200/sports/1/);
    opacity:0.4;
    position:absolute;
    top:0;
    left:0;
    height:200px;
    width:400px;
    z-index:0;
}
#content {
    z-index:1;
    position:relative;
}

In case entire entity is being return, better solution in spring JPA is use @Query(value = "from entity where Id in :ids")

This return entity type rather than object type

select sq.PARSING_SCHEMA_NAME, sq.LAST_LOAD_TIME, sq.ELAPSED_TIME, sq.ROWS_PROCESSED, ltrim(sq.sql_text), sq.SQL_FULLTEXT
  from v$sql sq, v$session se
 order by sq.ELAPSED_TIME desc, sq.LAST_LOAD_TIME desc;

for month

DateTime.Now.ToString("MM");

for day

DateTime.Now.ToString("dd");

for year

DateTime.Now.ToString("yyyy");

If you want to use ssh credentials,

  git(
       url: '[email protected]<repo_name>.git',
       credentialsId: 'xpc',
       branch: "${branch}"
    )

if you want to use username and password credentials, you need to use http clone as @Serban mentioned.

    git(
       url: 'https://github.com/<repo_name>.git',
       credentialsId: 'xpc',
       branch: "${branch}"
    )

With PowerShell version 4:

You can run a command as given below:

   Get-Service | select -property name,starttype

This SP looks very strange. It does not modify what is passed to @b. And nowhere in the SP you assign anything to @b. And @Password is not defined, so this SP will not work at all.

I would guess you actually want to return @Password, or to have SET @b = (SELECT...)

Much simpler will be if you modify your SP to (note, no OUTPUT parameter):

set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go

ALTER PROCEDURE [dbo].[Validate] @a varchar(50)

AS

SELECT TOP 1 Password FROM dbo.tblUser WHERE Login = @a

Then, your code can use cmd.ExecuteScalar, and receive the result.

You might consider this Open Source tool, matiri, https://github.com/AAFC-MBB/matiri which is a concurrent mysql backup script with metadata in Sqlite3. Features:

• Multi-Server: Multiple MySQL servers are supported whether they are co-located on the same or separate physical servers.
• Parallel: Each database on the server to be backed up is done separately, in parallel (concurrency settable: default: 3)
• Compressed: Each database backup compressed
• Checksummed: SHA256 of each compressed backup file stored and the archive of all files
• Archived: All database backups tar'ed together into single file
• Recorded: Backup information stored in Sqlite3 database

My Eclipse installation could not find log4j.properties when running JUnit tests from Eclipse, even though the file was located at src/test/resources.

The reason was that Eclipse (or the m2e connector) did not copy content from src/test/resources to the expected output folder target/test-classes - the root cause was that in the project's properties under Java Build Path -> Source tab -> Source folders on build path -> src/test/resources, somehow there was an Excluded: ** entry. I removed that excluded entry.

Alternatively, I could have manually copied src/test/resources/log4j.properties to target/test-classes/log4j.properties.

Yes there is a way

You can add some ALT+Letter shortcuts to the VBA editor environment. I added ALT+C to Comment selected text lines and A+X to Uncomment selected text lines:

1. In the VBE, right-click on a toolbar and select Customize
2. Optionally create a new toolbar
3. Select the Command Tab and 'Edit' in the Categories listbox. Find 'Comment Block' in the Commands listbox. Click and drag it to the target toolbar. Left-click on it to open the context popup menu and select 'Image and Text'. Replace the name with &C.
4. Repeat step 3 for the Uncomment Block command and replace the name with &X.
5. Close the Customize popup window.

There are built-in Alt+Letter commands that cannot be used for new shortcuts using letters: A,D,E,D,H,I,O,Q,R,T,V,W.

Text element inside Center of SizedBox work much better way, below Sample code

Widget build(BuildContext context) {
    return RawMaterialButton(
      fillColor: Colors.green,
      splashColor: Colors.greenAccent,
      shape: new CircleBorder(),
      child: Padding(
        padding: EdgeInsets.all(10.0),
        child: Row(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            SizedBox(
              width: 100.0,
              height: 100.0,
              child: Center(
                child: Text(
                widget.buttonText,
                maxLines: 1,
                style: TextStyle(color: Colors.white)
              ),
              )

        ),
    ),
  onPressed: widget.onPressed
);
}

Assuming a modern release, find -newermt is powerful:

find -newermt '10 minutes ago' ## other units work too, see `Date input formats`

or, if you want to specify a time_t (seconds since epoch):

find -newermt @1568670245

For reference, -newermt is not directly listed in the man page for find. Instead, it is shown as -newerXY, where XY are placeholders for mt. Other replacements are legal, but not applicable for this solution.

From man find -newerXY:

Time specifications are interpreted as for the argument to the -d option of GNU date.

So the following are equivalent to the initial example:

find -newermt "$(date '+%Y-%m-%d %H:%M:%S' -d '10 minutes ago')" ## long form using 'date'
find -newermt "@$(date +%s -d '10 minutes ago')" ## short form using 'date' -- notice '@'

The date -d (and find -newermt) arguments are quite flexible, but the documentation is obscure. Here's one source that seems to be on point: Date input formats

There is now a "native" solution on Windows 10, after enabling Bash on Windows, you can enter Bash shell by typing bash:

You can run Bash script like bash ./script.sh, but keep in mind that C drive is located at /mnt/c, and external hard drives are not mountable. So you might need to change your script a bit so it is compatible to Windows.

Also, even as root, you can still get permission denied when moving files around in /mnt, but you have your full root power in the / file system.

Also make sure your shell script is formatted with Unix style, or there can be errors.

int a,b,c,d;
if(scanf("%d %d %d %d",&a,&b,&c,&d) == 4) {
   //read the 4 integers
} else {
   puts("Error. Please supply 4 integers");
}

The custom format hh:mm only shows the number of hours correctly up to 23:59, after that, you get the remainder, less full days. For example, 48 hours would be displayed as 00:00, even though the underlaying value is correct.

To correctly display duration in hours and seconds (below or beyond a full day), you should use the custom format [h]:mm;@ In this case, 48 hours would be displayed as 48:00.

Cheers.

Use replaceFirst function of String class. There are so many variants of replace function that you can use.

They are indeed fools. If you look at RFC 3986 Appendix A, you will see that "space" is simply not mentioned anywhere in the grammar for defining a URL. Since it's not mentioned anywhere in the grammar, the only way to encode a space is with percent-encoding (%20).

In fact, the RFC even states that spaces are delimiters and should be ignored:

In some cases, extra whitespace (spaces, line-breaks, tabs, etc.) may have to be added to break a long URI across lines. The whitespace should be ignored when the URI is extracted.

and

For robustness, software that accepts user-typed URI should attempt to recognize and strip both delimiters and embedded whitespace.

Curiously, the use of + as an encoding for space isn't mentioned in the RFC, although it is reserved as a sub-delimeter. I suspect that its use is either just convention or covered by a different RFC (possibly HTTP).

I was confused as I knew VueJS should only contain 1 root element and yet I was still getting this same "template syntax error Component template should contain exactly one root element..." error on an extremely simple component. Turns out I had just mispelled </template> as </tempate> and that was giving me this same error in a few files I copied and pasted. In summary, check your syntax for any mispellings in your component.

You are testing against the string minus the last character:

>>> '"xxx"'[:-1]
'"xxx'

Note how the last character, the ", is not part of the output of the slice.

I think you wanted just to test against the last character; use [-1:] to slice for just the last element.

However, there is no need to slice here; just use str.startswith() and str.endswith() directly.

To check for duplicates you need to compare distinct pairs.

I used such way inside a method to check the passed in IEnumberable content

if( iEnum.Cast<Object>().Count() > 0) 
{

}

Inside a method like this:

GetDataTable(IEnumberable iEnum)
{  
    if (iEnum != null && iEnum.Cast<Object>().Count() > 0) //--- proceed further

}

You might want to take a look at the excellent HTTP Python library called Requests. It makes every task involving HTTP a bit easier than urllib2. From Cookies section of quickstart guide:

To send your own cookies to the server, you can use the cookies parameter:

>>> cookies = dict(cookies_are='working')

>>> r = requests.get('http://httpbin.org/cookies', cookies=cookies)
>>> r.text
'{"cookies": {"cookies_are": "working"}}'

Add this line to autoload.php in the application folder:

$autoload['time_zone'] = date_default_timezone_set('Asia/Kolkata');

Varying is an alias for varchar, so no difference, see documentation :)

The notations varchar(n) and char(n) are aliases for character varying(n) and character(n), respectively. character without length specifier is equivalent to character(1). If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.

then call the variable

            img: imgLink,
        }

#define PRINT if(0)print

The first comments out the PRINT instructions, the second prevents PRINT instruction because of a NULL if condition. If optimization is set, the compiler should strip out never executed instructions like: if(0) print("hello world"); or ((void)0);

To answer the original question on how to get the index as an integer for the desired selection, the following will work :

df[df['A']==5].index.item()

try

if ($('#column-left form:visible').length > 0) { ...

SELECT *
FROM
(
SELECT [Period], [Account], [Value]
FROM TableName
) AS source
PIVOT
(
    MAX([Value])
    FOR [Period] IN ([2000], [2001], [2002])
) as pvt

Another way,

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

You can use non-blocking sockets and one of pecl extensions for PHP:

• http://php.net/event
• http://php.net/libevent
• http://php.net/ev
• https://github.com/m4rw3r/php-libev

You can use library which gives you an abstraction layer between your code and a pecl extension: https://github.com/reactphp/event-loop

You can also use async http-client, based on the previous library: https://github.com/reactphp/http-client

See others libraries of ReactPHP: http://reactphp.org

Be careful with an asynchronous model. I recommend to see this video on youtube: http://www.youtube.com/watch?v=MWNcItWuKpI

What type() means:

I think your question is a bit more general than I originally thought. type() with one argument returns the type or class of the object. So if you have a = 'abc' and use type(a) this returns str because the variable a is a string. If b = 10, type(b) returns int.

See also python documentation on type().

For comparisons:

If you want a comparison you could use: if type(v) == h5py.h5r.Reference (to check if it is a h5py.h5r.Reference instance).

But it is recommended that one uses if isinstance(v, h5py.h5r.Reference) but then also subclasses will evaluate to True.

If you want to print the class use print v.__class__.__name__.

More generally: You can compare if two instances have the same class by using type(v) is type(other_v) or isinstance(v, other_v.__class__).

Assuming they always exist and are not part of your data, this will work:

declare @string varchar(8000) = '23;chair,red [$3]'
select substring(@string, charindex(';', @string) + 1, charindex(' [', @string) - charindex(';', @string) - 1)

Predicate<T> is a functional construct providing a convenient way of basically testing if something is true of a given T object.

For example suppose I have a class:

class Person {
    public string Name { get; set; }
    public int Age { get; set; }
}

Now let's say I have a List<Person> people and I want to know if there's anyone named Oscar in the list.

Without using a Predicate<Person> (or Linq, or any of that fancy stuff), I could always accomplish this by doing the following:

Person oscar = null;
foreach (Person person in people) {
    if (person.Name == "Oscar") {
        oscar = person;
        break;
    }
}

if (oscar != null) {
    // Oscar exists!
}

This is fine, but then let's say I want to check if there's a person named "Ruth"? Or a person whose age is 17?

Using a Predicate<Person>, I can find these things using a LOT less code:

Predicate<Person> oscarFinder = (Person p) => { return p.Name == "Oscar"; };
Predicate<Person> ruthFinder = (Person p) => { return p.Name == "Ruth"; };
Predicate<Person> seventeenYearOldFinder = (Person p) => { return p.Age == 17; };

Person oscar = people.Find(oscarFinder);
Person ruth = people.Find(ruthFinder);
Person seventeenYearOld = people.Find(seventeenYearOldFinder);

Notice I said a lot less code, not a lot faster. A common misconception developers have is that if something takes one line, it must perform better than something that takes ten lines. But behind the scenes, the Find method, which takes a Predicate<T>, is just enumerating after all. The same is true for a lot of Linq's functionality.

So let's take a look at the specific code in your question:

Predicate<int> pre = delegate(int a){ return a % 2 == 0; };

Here we have a Predicate<int> pre that takes an int a and returns a % 2 == 0. This is essentially testing for an even number. What that means is:

pre(1) == false;
pre(2) == true;

And so on. This also means, if you have a List<int> ints and you want to find the first even number, you can just do this:

int firstEven = ints.Find(pre);

Of course, as with any other type that you can use in code, it's a good idea to give your variables descriptive names; so I would advise changing the above pre to something like evenFinder or isEven -- something along those lines. Then the above code is a lot clearer:

int firstEven = ints.Find(evenFinder);

In my case, using Mockito 2.0, I had to change all the any() parameters to nullable() in order to stub the real call.

If you're not using SQL Server 2008 (i.e. you only have a DateTime data type), you can use the following (admittedly rough and ready) TSQL to achieve what you want:

DECLARE @DateOnly AS datetime
DECLARE @TimeOnly AS datetime 

SET @DateOnly = '07 aug 2009 00:00:00'
SET @TimeOnly = '01 jan 1899 10:11:23'


-- Gives Date Only.
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, @DateOnly))

-- Gives Time Only.
SELECT DATEADD(Day, -DATEDIFF(Day, 0, @TimeOnly), @TimeOnly)

-- Concatenates Date and Time parts.
SELECT
CAST(
    DATEADD(dd, 0, DATEDIFF(dd, 0, @DateOnly)) + ' ' +
    DATEADD(Day, -DATEDIFF(Day, 0, @TimeOnly), @TimeOnly)           
as datetime)

It's rough and ready, but it works!

There is a difference between the navigation bar and the status bar. The confusing part is that it looks like one solid feature at the top of the screen, but the areas can actually be separated into two distinct views; a status bar and a navigation bar. The status bar spans from y=0 to y=20 points and the navigation bar spans from y=20 to y=64 points. So the navigation bar (which is where the page title and navigation buttons go) has a height of 44 points, but the status bar and navigation bar together have a total height of 64 points.

Here is a great resource that addresses this question along with a number of other sizing idiosyncrasies in iOS7: http://ivomynttinen.com/blog/the-ios-7-design-cheat-sheet/

They don't have similar meanings. 'src' indicates a resource the browser should fetch as part of the current page. HREF indicatea a resource to be fetched if the user requests it.

I think the python memcached API is the prevalent tool, but I haven't used it myself and am not sure whether it supports the features you need.

I prefer:

config/initializers/string.rb

class String
  def number?
    Integer(self).is_a?(Integer)
  rescue ArgumentError, TypeError
    false
  end
end

and then:

[218] pry(main)> "123123123".number?
=> true
[220] pry(main)> "123 123 123".gsub(/ /, '').number?
=> true
[222] pry(main)> "123 123 123".number?
=> false

or check phone number:

"+34 123 456 789 2".gsub(/ /, '').number?

You can delete the features folder just like any other in your checkout then commit the change.

To prevent this in the future I suggest you follow the naming conventions for SVN layout.

Either give each project a trunk, branches, tags folder when they are created.

svn
+ project1
  + trunk
    + src
    + etc...
  + branches
    + features
      + src
      + etc...
  + tags
+ project2
  + trunk
  + branches
  + tags

I don't think they are reprinting paper books each year. The copyright of the year when the book was printed is valid in all next years.

The same principle should apply to web pages, too. However "the year when website was created" is a bit different. So, if you make changes to your web site - you are not done yet. Hence, when updating the site, you may want to update the copyright year.

Foreach-object operation statement:

To load other file(css ,js) and folder(images) , in codeigniter project

we have to follow two simple step:

1.create folder public (can give any name) in your codeigniters folder put your bootstrap files css and js folder in side public folder. https://i.stack.imgur.com/O2gr6.jpg

2.now we have to use two line of code 1.load->helper('url'); ?> 2.

go to your view file

put first line to load base URL

   <?php $this->load->helper('url'); ?>

secondly in your html head tag put this

   <link rel="stylesheet" type="text/css" href="<?php echo base_url(); ?>/public/css/bootstrap.css">

now you can enjoy the bootstrap in your codeigniter

Here is a more modular and cleaner way to circle crop your bitmap in Glide:

1. Create a custom transformation by extending BitmapTransformation then override transform method like this :

For Glide 4.x.x

public class CircularTransformation extends BitmapTransformation {

@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
    RoundedBitmapDrawable circularBitmapDrawable =
            RoundedBitmapDrawableFactory.create(null, toTransform);
    circularBitmapDrawable.setCircular(true);
    Bitmap bitmap = pool.get(outWidth, outHeight, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    circularBitmapDrawable.setBounds(0, 0, outWidth, outHeight);
    circularBitmapDrawable.draw(canvas);
    return bitmap;
    }

@Override
public void updateDiskCacheKey(MessageDigest messageDigest) {}

}

For Glide 3.x.x

public class CircularTransformation extends BitmapTransformation {

@Override
protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
    RoundedBitmapDrawable circularBitmapDrawable =
            RoundedBitmapDrawableFactory.create(null, toTransform);
    circularBitmapDrawable.setCircular(true);
    Bitmap bitmap = pool.get(outWidth, outHeight, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    circularBitmapDrawable.setBounds(0, 0, outWidth, outHeight);
    circularBitmapDrawable.draw(canvas);
    return bitmap;
    }

@Override
public String getId() {
    // Return some id that uniquely identifies your transformation.
    return "CircularTransformation";
    }

}

2. Then set it in Glide builder where you need it:

Glide.with(yourActivity)
   .load(yourUrl)
   .asBitmap()
   .transform(new CircularTransformation())
   .into(yourView);

Hope this helps :)

lowercase-with-hyphens is the style I most often see on GitHub.*

lowercase_with_underscores is probably the second most popular style I see.

The former is my preference because it saves keystrokes.

Again, I stress that namespace, svc name and contract must be correctly specified in web.config file:

 <service name="NAMESPACE.SvcFileName">
    <endpoint contract="NAMESPACE.IContractName" />
  </service>

Example:

<service name="MyNameSpace.FileService">
<endpoint contract="MyNameSpace.IFileService" />
</service>

May help you.

• Delete All folders you have created previously
• Create fresh folder
• Then try navigate to that folder from command "cd foldername"
• then try to install "npm install"

This will solve you problem.

In case somebody wonders what is the faster way to filter (the accepted answer or the one from @redreamality):

import pandas as pd
import numpy as np

length = 100_000
df = pd.DataFrame()
df['Year'] = np.random.randint(1950, 2019, size=length)
df['Gender'] = np.random.choice(['Male', 'Female'], length)

%timeit df.query('Gender=="Male" & Year=="2014" ')
%timeit df[(df['Gender']=='Male') & (df['Year']==2014)]

Results for 100,000 rows:

6.67 ms ± 557 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
5.54 ms ± 536 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Results for 10,000,000 rows:

326 ms ± 6.52 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
472 ms ± 25.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

So results depend on the size and the data. On my laptop, query() gets faster after 500k rows. Further, the string search in Year=="2014" has an unnecessary overhead (Year==2014 is faster).

1. Replace the button with a submit
2. Be progressive, make sure you have a server side version
3. Bind your JavaScript to the submit handler of the form, not the click handler of the button

Pressing enter in the field will trigger form submission, and the submit handler will fire.

I use the little utility which comes with PureMPI.net called execcmd.exe. Its syntax is as follows:

execcmd \\yourremoteserver <your command here>

Doesn't get any simpler than this :)

You could try something like:

char ch;
fstream fin("file", fstream::in);
while (fin >> noskipws >> ch) {
    cout << ch; // Or whatever
}

Multiple SQL statements must be executed with the mysqli_multi_query() function.

Example (MySQLi Object-oriented):

    <?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO names (firstname, lastname)
VALUES ('inpute value here', 'inpute value here');";
$sql .= "INSERT INTO phones (landphone, mobile)
VALUES ('inpute value here', 'inpute value here');";

if ($conn->multi_query($sql) === TRUE) {
    echo "New records created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>

Use Object.keys to get an array of the properties on an object. Example:

var example = {
    foo1: { /* stuff1 */},
    foo2: { /* stuff2 */},
    foo3: { /* stuff3 */}
};

var keys = Object.keys(example); // => ["foo1", "foo2", "foo3"] (Note: the order here is not reliable)

Documentation and cross-browser shim provided here. An example of its use can be found in another one of my answers here.

Edit: for clarity, I just want to echo what was correctly stated in other answers: the key order in javascript objects is undefined.

#include"stdio.h"//rmv coding for randam number access

#include"conio.h"

#include"time.h"

void main()
{
    time_t t;
    int rmvivek;

    srand(time(&t));
    rmvivek=1;

    while(rmvivek<=5)
    {
        printf("%c\t",rand()%10);
        rmvivek++;
    }
    getch();
}

valign="top" should do the work.

<tr>_x000D_
  <td valign="top">Description</td>_x000D_
</tr>

As an ArrayList that line would be

import java.util.ArrayList;
...
ArrayList<Card> hand = new ArrayList<Card>();

To use the ArrayList you have do

hand.get(i); //gets the element at position i 
hand.add(obj); //adds the obj to the end of the list
hand.remove(i); //removes the element at position i
hand.add(i, obj); //adds the obj at the specified index
hand.set(i, obj); //overwrites the object at i with the new obj

Also read this http://docs.oracle.com/javase/6/docs/api/java/util/ArrayList.html

This is an old, but still relevant question, and while the answers here are helpful no one answer fully addressed both of the OP's questions.

1. Do I have to install ODP.NET and Oracle client on the computer that I want to run my application?

YES - if you are using ODP.NET, Unmanaged. This is the version that you typically install when you choose "Oracle Data Provider for .NET" in the Oracle Client installer (for example). You Download this from Oracle (just google it: Oracle URLs change often).

But If you are using ODP.NET, Managed (and you probably want to use this one this instead) then No, you only need to install (or deploy) ODP.NET, Managed with the app, not the full Oracle Client. See below for details.

2. If yes, is there other way that I don't have to install them but still can run my application?

Yes, there is at least one way. And it is the Managed port of ODP.NET.

Unfortunately the usual workarounds, including ODBC, Microsoft's Oracle Provider for .NET (yes, that old, deprecated one), and the ODP.NET, Unmanaged DLL all require the Oracle client to be installed. It wasn't until our friends at Oracle gave us a nice little (~5MB) DLL that is also Managed. This means no more having to depoy 32-bit and 64-bit versions to go with 32-bit and 64-bit Oracle clients! And no more issues with assembly binding where you build against 10.0.2.1 (or whatever) but your customers install a range of clients from 9i all the way to 12c, including the 'g' ones in the middle) because you can just ship it with your app, and manage it via nuget.

But if you use ODP.NET, Managed which is available as a nuget package, then you do not need to install the Oracle Client. You only need the ODP.NET, Managed DLL. And if you were previously using the ODP.NET, Unmanaged DLL, it is very easy to switch: simply change all your references to the Managed ODP.NET (.csproj files in csharp, etc.), and then change any using statements, for example: using Oracle.DataAccess.Client becomes using Oracle.ManagedDataAccess.Client and that's it! (Unless you were supposedly using some of the more advanced DB management features in the full client that are exposed in the ODP.NET, Unmanaged, which I have not done myself, so good luck with that..). And also nuke all of those annoying assemblyBindingRedirect nodes from your app.config/web.config files and never sweat that junk again!

References:

• ODP.NET Details: http://www.oracle.com/technetwork/topics/dotnet/index-085163.html
• ODP.NET is backward and foward-compatible: http://www.oracle.com/technetwork/topics/dotnet/multipledbs-089665.html
• Advanced Configuration: https://docs.oracle.com/cd/E48297_01/doc/win.121/e41125/featConfig.htm

Troubleshooting:

That error typically means ODP.NET was found OK, but Oracle client was not found or not installed. This could also occur when the architecture doesn't match (32-bit Oracle client is installed, but trying to use 64-bit Unmanaged ODP.NET, or vice versa). This can also happen due to permissions issues and path issues and other problems with the app domain (your web app or your EXE or whatever) not being able to find the Oracle DLLs to actually communicate with Oracle over the network (the ODP.NET Unmanaged DLLs are basically just wrappers for this that hook into ADO and stuff).

Common solutions I have found to this problem:

App is 64-bit?

• Install 64-bit Oracle Client (32-bit one wont work)

App is 32-bit?

• Install 32-bit Oracle Client (64-bit one wont work)

Oracle Client is already installed for the correct architecture?

• Verify your environment PATH and ORACLE_HOME variables, make sure Oracle can be found (newer versions may use Registry instead)
• Verify the ORACLE_HOME and settings in the Registry (And remember: Registry is either 32-bit or 64-bit, so make sure you check the one that matches your app!)
• Verify permissions on the ORACLE_HOME folder. If you don't know where this is, check the Registry. I have seen cases where ASP.NET app worker process was using Network Service user and for some reason installing 32-bit and 64-bit clients side by side resulted in the permissions being removed from the first client for the Authorized Users group.. fixing perms on the home folder fixed this.
• As always, it is handy to Use SysInternals Process Monitor to find out what file is missing or can't be read.

Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:

#container {
    min-width:800px;
    width: auto !important;
    width:800px;
}

That will effectively give you 800px min-width in IE6 and any up-to-date browsers.

use fwrite() instead of file_put_contents()

Use Cheerio. It isn't as strict as jsdom and is optimized for scraping. As a bonus, uses the jQuery selectors you already know.

? Familiar syntax: Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API.

? Blazingly fast: Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Preliminary end-to-end benchmarks suggest that cheerio is about 8x faster than JSDOM.

? Insanely flexible: Cheerio wraps around @FB55's forgiving htmlparser. Cheerio can parse nearly any HTML or XML document.

Note: I'm assuming you have configured authentication separately. Below code is to download the single object from the S3 bucket.

import boto3

#initiate s3 client 
s3 = boto3.resource('s3')

#Download object to the file    
s3.Bucket('mybucket').download_file('hello.txt', '/tmp/hello.txt')

In Linux the graphical user interface is not a part of the operating system. The graphical user interface found on most Linux desktops is provided by software called the X Window System, which defines a device independent way of dealing with screens, keyboards and pointer devices.

X Window defines a network protocol for communication, and any program that knows how to "speak" this protocol can use it. There is a C library called Xlib that makes it easier to use this protocol, so Xlib is kind of the native GUI API. Xlib is not the only way to access an X Window server; there is also XCB.

Toolkit libraries such as GTK+ (used by GNOME) and Qt (used by KDE), built on top of Xlib, are used because they are easier to program with. For example they give you a consistent look and feel across applications, make it easier to use drag-and-drop, provide components standard to a modern desktop environment, and so on.

How X draws on the screen internally depends on the implementation. X.org has a device independent part and a device dependent part. The former manages screen resources such as windows, while the latter communicates with the graphics card driver, usually a kernel module. The communication may happen over direct memory access or through system calls to the kernel. The driver translates the commands into a form that the hardware on the card understands.

As of 2013, a new window system called Wayland is starting to become usable, and many distributions have said they will at some point migrate to it, though there is still no clear schedule. This system is based on OpenGL/ES API, which means that in the future OpenGL will be the "native GUI API" in Linux. Work is being done to port GTK+ and QT to Wayland, so that current popular applications and desktop systems would need minimal changes. The applications that cannot be ported will be supported through an X11 server, much like OS X supports X11 apps through Xquartz. The GTK+ port is expected to be finished within a year, while Qt 5 already has complete Wayland support.

To further complicate matters, Ubuntu has announced they are developing a new system called Mir because of problems they perceive with Wayland. This window system is also based on the OpenGL/ES API.

2 points in addition to all other good answers:

1:

what are the Grant Tables?

from dev.mysql.com

The MySQL system database includes several grant tables that contain information about user accounts and the privileges held by them.

clari?cation: in MySQL, there are some inbuilt databases , one of them is "mysql" , all the tables on "mysql" database have been called as grant tables

2:

note that if you perform:

UPDATE a_grant_table SET password=PASSWORD('1234') WHERE test_col = 'test_val';

and refresh phpMyAdmin , you'll realize that your password has been changed on that table but even now if you perform:

mysql -u someuser -p

your access will be denied by your new password until you perform :

FLUSH PRIVILEGES;

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

TypeScript have a way of validating the type of a variable in runtime. You can add a validating function that returns a type predicate. So you can call this function inside an if statement, and be sure that all the code inside that block is safe to use as the type you think it is.

Example from the TypeScript docs:

function isFish(pet: Fish | Bird): pet is Fish {
   return (<Fish>pet).swim !== undefined;
}

// Both calls to 'swim' and 'fly' are now okay.
if (isFish(pet)) {
  pet.swim();
}
else {
  pet.fly();
}

    canvas.width = width;
    canvas.height = height;
    ctx = canvas.getContext("2d");
    ctx.drawImage(img, 0, 0, width, height);
    let result = await new Promise<Blob>(resolve => { canvas.toBlob(resolve, 'image/jpeg', 0.95); });
    return result;
}

You must also have the following imports in order to import the DLL

using System.Runtime.InteropServices;
using System.Diagnostics;

The correct recursive command is:

sudo chmod -R 755 /opt/lampp/htdocs

-R: change every sub folder including the current folder

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Docs: man locale, man setlocale.

I'm not suggested this as the best answer, just an alternative but you can also do something like:

flag = reader[0] == "True"

flag will be True id reader[0] is "True", otherwise it will be False.

I also had this problem with implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'.

The solution for me was to go File -> Invalidate Caches / Restart -> Invalidate -> Close Project -> Remove project from project window -> Open Project (from project window).

The character set is part of the locale, which is determined by the value of NLS_LANG. As the documentation makes clear this is an operating system variable:

NLS_LANG is set as an environment variable on UNIX platforms. NLS_LANG is set in the registry on Windows platforms.

Now we can use ALTER SESSION to change the values for a couple of locale elements, NLS_LANGUAGE and NLS_TERRITORY. But not, alas, the character set. The reason for this discrepancy is - I think - that the language and territory simply effect how Oracle interprets the stored data, e.g. whether to display a comma or a period when displaying a large number. Wheareas the character set is concerned with how the client application renders the displayed data. This information is picked up by the client application at startup time, and cannot be changed from within.

$("input[@name='<%=test2.ClientID%>']:checked");

use this and here ClientID fetch random id created by .net.

update() is now deprecated and you should use replace_one(), update_one(), or update_many() instead.

In my case I used update_many() and it solved my issue:

db.your_collection.update_many({}, {"$set": {"new_field": "value"}}, upsert=False, array_filters=None)

From documents

update_many(filter, update, upsert=False, array_filters=None, bypass_document_validation=False, collation=None, session=None)


filter: A query that matches the documents to update.

update: The modifications to apply.

upsert (optional): If True, perform an insert if no documents match the filter.

bypass_document_validation (optional): If True, allows the write to opt-out of document level validation. Default is False.

collation (optional): An instance of Collation. This option is only supported on MongoDB 3.4 and above.

array_filters (optional): A list of filters specifying which array elements an update should apply. Requires MongoDB 3.6+.

session (optional): a ClientSession.

If the other answers aren't working for you, there's also a homepage field in package.json. After running npm run build you should get a message like the following:

The project was built assuming it is hosted at the server root.
To override this, specify the homepage in your package.json.
For example, add this to build it for GitHub Pages:

  "homepage" : "http://myname.github.io/myapp",

You would just add it as one of the root fields in package.json, e.g.

{
  // ...
  "scripts": {
    // ...
  },
  "homepage": "https://example.com"
}

When it's successfully set, either via homepage or PUBLIC_URL, you should instead get a message like this:

The project was built assuming it is hosted at https://example.com.
You can control this with the homepage field in your package.json.

It's perfectly possible to template a class on an integer rather than a type. We can assign the templated value to a variable, or otherwise manipulate it in a way we might with any other integer literal:

unsigned int x = N;

In fact, we can create algorithms which evaluate at compile time (from Wikipedia):

template <int N>
struct Factorial 
{
     enum { value = N * Factorial<N - 1>::value };
};

template <>
struct Factorial<0> 
{
    enum { value = 1 };
};

// Factorial<4>::value == 24
// Factorial<0>::value == 1
void foo()
{
    int x = Factorial<4>::value; // == 24
    int y = Factorial<0>::value; // == 1
}

Seems your resource POSTmethod won't get hit as @peeskillet mention. Most probably your ~POST~ request won't work, because it may not be a simple request. The only simple requests are GET, HEAD or POST and request headers are simple(The only simple headers are Accept, Accept-Language, Content-Language, Content-Type= application/x-www-form-urlencoded, multipart/form-data, text/plain).

Since in you already add Access-Control-Allow-Origin headers to your Response, you can add new OPTIONS method to your resource class.

    @OPTIONS
@Path("{path : .*}")
public Response options() {
    return Response.ok("")
            .header("Access-Control-Allow-Origin", "*")
            .header("Access-Control-Allow-Headers", "origin, content-type, accept, authorization")
            .header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD")
            .header("Access-Control-Max-Age", "2000")
            .build();
}

It is probably little bit late, but I managed to solve it this way -> open with winrar and delete ECLIPSEF.RSA and ECLIPSEF.SF in META-INF folder, moreover put "Main-class: main_class_name" (without ".class") in MANIFEST.MF. Make sure that you pressed "Enter" twice after the last line, otherwise it won't work.

You can't rely on context menus because the user can deactivate it. Most websites want to use the feature to annoy the visitor.

You can use:

Select
     count(created_date) as counted_leads,
     created_date as count_date
from
     table
group by
     created_date

This is the best solution IMHO. It covers BOTH null and empty scenario, as is easy to understand when reading the code. All you need to know is that .getProperty returns a null when system prop is not set:

String DEFAULT_XYZ = System.getProperty("user.home") + "/xyz";
String PROP = Optional.ofNullable(System.getProperty("XYZ"))
        .filter(s -> !s.isEmpty())
        .orElse(DEFAULT_XYZ);

The -expandproperty does not work with more than 1 object. You can use this one :

Select-Object Name | ForEach-Object {$_.Name}

If there is more than one value then :

Select-Object Name, Country | ForEach-Object {$_.Name + " " + $Country}

I use something similar (basically it's the same approach). Sometimes it's useful to have a mock object return pre-defined output for certain inputs. That goes like this:

private Hashtable<InputObject,  OutputObject> table = new Hashtable<InputObject, OutputObject>();
table.put(input1, ouput1);
table.put(input2, ouput2);

...

when(mockObject.method(any(InputObject.class))).thenAnswer(
       new Answer<OutputObject>()
       {
           @Override
           public OutputObject answer(final InvocationOnMock invocation) throws Throwable
           {
               InputObject input = (InputObject) invocation.getArguments()[0];
               if (table.containsKey(input))
               {
                   return table.get(input);
               }
               else
               {
                   return null; // alternatively, you could throw an exception
               }
           }
       }
       );

Expanding on Xin's answer and assuming the comparison value type is INT, this approach works too:

SELECT IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)

This is a full test with example values:

DECLARE @A AS INT
DECLARE @B AS INT

SELECT  @A = 2, @B = 1
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 2

SELECT  @A = 2, @B = 3
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 3

SELECT  @A = 2, @B = NULL
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 2    

SELECT  @A = NULL, @B = 1
SELECT  IIF(ISNULL(@A, -2147483648) > ISNULL(@B, -2147483648), @A, @B)
-- 1

$("#table tr").click(function(){
   $(this).addClass('selected').siblings().removeClass('selected');    
   var value=$(this).find('td:first').html();
   alert(value);    
});

$('.ok').on('click', function(e){
    alert($("#table tr.selected td:first").html());
});

If you're using an MVVM library such as knockout.js (which I highly recommend) you can do it more cleanly:

<div class="alert alert-info alert-dismissible" data-bind="visible:showAlert">
   <button type="button" class="close" data-bind="click:function(){showAlert(false);}>
        <span aria-hidden="true">&times;</span>
        <span class="sr-only">Close</span>
   </button>
   Warning! Better check yourself, you're not looking too good.
</div>

Try this:

subset(studentdata, Drink=='water')

that should do it.

if (Arrays.asList(array).contains(string))

To see all keys of Jsonobject use this

    String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";
    JSONObject obj = new JSONObject(JSON);
    Iterator iterator = obj.keys();
    String key = null;
    while (iterator.hasNext()) {
        key = (String) iterator.next();
        System.out.pritnln(key);
    } 

If this is in fact a ListObject table (Insert Table from the ribbon) then you can use the table's .DataBodyRange object to get the number of rows and columns. This ignores the header row.

Sub TableTest()

Dim tbl As ListObject
Dim tRows As Long
Dim tCols As Long

Set tbl = ActiveSheet.ListObjects("Table1")  '## modify to your table name.

With tbl.DataBodyRange
    tRows = .Rows.Count
    tCols = .Columns.Count
End With

MsgBox tbl.Name & " contains " & tRows & " rows and " & tCols & " columns.", vbInformation

End Sub

If you need to use the header row, instead of using tbl.DataBodyRange just use tbl.Range.

You've specifically mentioned a "variable-length array" in your question, so neither of the existing two answers (as I write this) are quite right.

Java doesn't have any concept of a "variable-length array", but it does have Collections, which serve in this capacity. Any collection (technically any "Iterable", a supertype of Collections) can be looped over as simply as this:

Collection<Thing> things = ...;
for (Thing t : things) {
  System.out.println(t);
}

EDIT: it's possible I misunderstood what he meant by 'variable-length'. He might have just meant it's a fixed length but not every instance is the same fixed length. In which case the existing answers would be fine. I'm not sure what was meant.

Complete copy&paste recipe, just adding the commands in the comments (for the copy-paste solution), after testing them:

git filter-branch --tree-filter 'rm -rf node_modules' --prune-empty HEAD
echo node_modules/ >> .gitignore
git add .gitignore
git commit -m 'Removing node_modules from git history'
git gc
git push origin master --force

After this, you can remove the line "node_modules/" from .gitignore

Take a look at the documentation for HttpServletRequest.
In order to build the URL in your example you will need to use:

• getScheme()
• getServerName()
• getServerPort()
• getContextPath()

Here is a method that will return your example:

public static String getURLWithContextPath(HttpServletRequest request) {
   return request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath();
}

This is now supported in Chrome by the "Pause on all exceptions" button.

To enable it:

• Go to the "Sources" tab in Chrome Developer Tools
• Click the "Pause" button at the bottom of the window to switch to "Pause on all exceptions mode".

Note that this button has multiple states. Keep clicking the button to switch between

• "Pause on all exceptions" - the button is colored light blue
• "Pause on uncaught exceptions", the button is colored purple.
• "Dont pause on exceptions" - the button is colored gray

Example of using a Timer:

using System;
using System.Timers;

static void Main(string[] args)
{
    Timer t = new Timer(TimeSpan.FromMinutes(5).TotalMilliseconds); // Set the time (5 mins in this case)
    t.AutoReset = true;
    t.Elapsed += new System.Timers.ElapsedEventHandler(your_method);
    t.Start();
}

// This method is called every 5 mins
private static void your_method(object sender, ElapsedEventArgs e)
{
    Console.WriteLine("..."); 
}

use $("#selector").get(0) to check with null like that. get returns the dom element, until then you re dealing with an array, where you need to check the length property. I personally don't like length check for null handling, it confuses me for some reason :)

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); }

So if I wanted to return a first name and last name like: Hello Fred Gerbig I would use the code below, this code works but is it actually the most correct way to do it?

import sys
def main():
  if len(sys.argv) >= 2:
    fname = sys.argv[1]
    lname = sys.argv[2]
  else:
    name = 'World'
  print 'Hello', fname, lname
if __name__ == '__main__':
  main()

Edit: Found that the above code works with 2 arguments but crashes with 1. Tried to set len to 3 but that did nothing, still crashes (re-read the other answers and now understand why the 3 did nothing). How do I bypass the arguments if only one is entered? Or how would error checking look that returned "You must enter 2 arguments"?

Edit 2: Got it figured out:

import sys
def main():
  if len(sys.argv) >= 2:
    name = sys.argv[1] + " " + sys.argv[2]
  else:
    name = 'World'
  print 'Hello', name
if __name__ == '__main__':
  main()

Select 3.*

Please see Update select2 data without rebuilding the control as this may be a duplicate. Another way is to destroy and then recreate the select2 element.

$("#dropdown").select2("destroy");

$("#dropdown").select2();

If you are having problems with resetting the state/region on country change try clearing the current value with

$("#dropdown").select2("val", "");

You can view the documentation here http://ivaynberg.github.io/select2/ that outlines nearly/all features. Select2 supports events such as change that can be used to update the subsequent dropdowns.

$("#dropdown").on("change", function(e) {});

Select 4.* Update

You can now update the data/list without rebuilding the control using:

fooBarDropdown.select2({
    data: fromAccountData
});

Just want to summarize the answers and comments. There are a number of ways doing a pagination.

Prior to oracle 12c there were no OFFSET/FETCH functionality, so take a look at whitepaper as the @jasonk suggested. It's the most complete article I found about different methods with detailed explanation of advantages and disadvantages. It would take a significant amount of time to copy-paste them here, so I won't do it.

There is also a good article from jooq creators explaining some common caveats with oracle and other databases pagination. jooq's blogpost

Good news, since oracle 12c we have a new OFFSET/FETCH functionality. OracleMagazine 12c new features. Please refer to "Top-N Queries and Pagination"

You may check your oracle version by issuing the following statement

SELECT * FROM V$VERSION

You don't use the : syntax - pull always modifies the currently checked-out branch. Thus:

git pull origin my_remote_branch

while you have my_local_branch checked out will do what you want.

Since you already have the tracking branch set, you don't even need to specify - you could just do...

git pull

while you have my_local_branch checked out, and it will update from the tracked branch.

Sessions - what Chris Thompson said.

Instantiation - a servlet is instantiated when the container receives the first request mapped to the servlet (unless the servlet is configured to load on startup with the <load-on-startup> element in web.xml). The same instance is used to serve subsequent requests.

This is an example of how to POST multi-part data WITHOUT using external Apache libraries:

byte[] buffer = getBuffer();

if(buffer.length > 0) {
   String lineEnd = "\r\n"; 
   String twoHyphens = "--"; 
   String boundary =  "RQdzAAihJq7Xp1kjraqf"; 

   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   DataOutputStream dos = new DataOutputStream(baos);

   // Send parameter #1
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param1\"" + lineEnd);
   dos.writeBytes("Content-Type: text/plain; charset=US-ASCII" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: 8bit" + lineEnd);
   dos.writeBytes(lineEnd);
   dos.writeBytes(myStringData + lineEnd);

   // Send parameter #2
   //dos.writeBytes(twoHyphens + boundary + lineEnd); 
   //dos.writeBytes("Content-Disposition: form-data; name=\"param2\"" + lineEnd + lineEnd);
   //dos.writeBytes("foo2" + lineEnd);

   // Send a binary file
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param3\";filename=\"test_file.dat\"" + lineEnd); 
   dos.writeBytes("Content-Type: application/octet-stream" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: binary" + lineEnd);
   dos.writeBytes(lineEnd); 
   dos.write(buffer);
   dos.writeBytes(lineEnd); 
   dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
   dos.flush(); 
   dos.close();

   ByteArrayInputStream content = new ByteArrayInputStream(baos.toByteArray());
   BasicHttpEntity entity = new BasicHttpEntity();
   entity.setContent(content);

   HttpPost httpPost = new HttpPost(myURL);
   httpPost.addHeader("Connection", "Keep-Alive");
   httpPost.addHeader("Content-Type", "multipart/form-data; boundary="+boundary);

   //MultipartEntity entity = new MultipartEntity();
   //entity.addPart("param3", new ByteArrayBody(buffer, "test_file.dat"));
   //entity.addPart("param1", new StringBody(myStringData));

   httpPost.setEntity(entity);

   /*
   String httpData = "";
   ByteArrayOutputStream baos1 = new ByteArrayOutputStream();
   entity.writeTo(baos1);
   httpData = baos1.toString("UTF-8");
   */

   /*
   Header[] hdrs = httpPost.getAllHeaders();
   for(Header hdr: hdrs) {
     httpData += hdr.getName() + " | " + hdr.getValue() + " |_| ";
   }
   */

   //Log.e(TAG, "httpPost data: " + httpData);
   response = httpClient.execute(httpPost);
}

Use tmuxinator - it allows you to have multiple sessions configured, and you can choose which one to launch at any given time. You can launch commands in particular windows or panes and give titles to windows. Here is an example use with developing Django applications.

Sample config file:

# ~/.tmuxinator/project_name.yml
# you can make as many tabs as you wish...

project_name: Tmuxinator
project_root: ~/code/rails_project
socket_name: foo # Not needed. Remove to use default socket
rvm: 1.9.2@rails_project
pre: sudo /etc/rc.d/mysqld start
tabs:
  - editor:
      layout: main-vertical
      panes:
        - vim
        - #empty, will just run plain bash
        - top
  - shell: git pull
  - database: rails db
  - server: rails s
  - logs: tail -f logs/development.log
  - console: rails c
  - capistrano:
  - server: ssh me@myhost

The method buildSessionFactory is deprecated from the Hibernate 4 release and it is replaced with the new API. If you are using the Hibernate 4.3.0 and above, your code has to be:

Configuration configuration = new Configuration().configure();

StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
        .applySettings(configuration.getProperties());

SessionFactory factory = configuration.buildSessionFactory(builder.build());

There's a far more simpler solution to tackle this.

The reason why you get ValueError: Index contains duplicate entries, cannot reshape is because, once you unstack "Location", then the remaining index columns "id" and "date" combinations are no longer unique.

You can avoid this by retaining the default index column (row #) and while setting the index using "id", "date" and "location", add it in "append" mode instead of the default overwrite mode.

So use,

e.set_index(['id', 'date', 'location'], append=True)

Once this is done, your index columns will still have the default index along with the set indexes. And unstack will work.

Let me know how it works out.

You are copying all files to a single file called TEST_BACKUP_FOLDER

try this:

md TEST_BACKUP_FOLDER
copy "\\My_Servers_IP\Shared Drive\FolderName\*" TEST_BACKUP_FOLDER

If you are allowed to go further then javascript/html facilities - I would use the apache web server to represent your directory listing via http.

If this solution is appropriate. these are the steps:

1. download apache hhtp server from one of the mirrors http://httpd.apache.org/download.cgi

2. unzip/install (if msi) it to the directory e.g C:\opt\Apache (the instruction is for windows)

3. map the network forlder as a local drive on windows (\server\folder to let's say drive H:)

4. open conf/httpd.conf file

5. make sure the next line is present and not commented

   LoadModule autoindex_module modules/mod_autoindex.so

6. Add directory configuration

<Directory "H:/path">

Options +Indexes

AllowOverride None

Order allow,deny

Allow from all

</Directory> 7. Start the web server and make sure the directory listingof the remote folder is available by http. hit localhost/path 8. use a frame inside your web page to access the listing

What is missed: 1. you mignt need more fancy configuration for the host name, refer to Apache Web Server docs. Register the host name in DNS server

1. the mapping to the network drive might not work, i did not check. As a posible resolution - host your web server on the same machine as smb server.

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

Just notice that if you work with Fragments using ViewPager, it's pretty easy. You only need to call this method: setOffscreenPageLimit().

Accordign to the docs:

Set the number of pages that should be retained to either side of the current page in the view hierarchy in an idle state. Pages beyond this limit will be recreated from the adapter when needed.

Similar issue here

i try to use the sentence of a prior post and don't work recursively, then read some help and get this line:

find . -name "*.pyc" -exec git rm -f "{}" \;

p.d. is necessary to add *.pyc in .gitignore file to maintain git clean

echo "*.pyc" >> .gitignore

Enjoy.

saveLeaves(vec,msh);
I'm assuming takes the msh pointer and puts it inside of vec. Since msh is just a pointer to the memory, if you delete it, it will also get deleted inside of the vector.

That's more specifically a ternary operator expression than an if-then, here's the python syntax

value_when_true if condition else value_when_false

Better Example: (thanks Mr. Burns)

'Yes' if fruit == 'Apple' else 'No'

Now with assignment and contrast with if syntax

fruit = 'Apple'
isApple = True if fruit == 'Apple' else False

vs

fruit = 'Apple'
isApple = False
if fruit == 'Apple' : isApple = True

To merge one branch into another, such as merging "feature_x" branch into "master" branch:

git checkout master

git merge feature_x

This page is the first result for several search engines when looking for "git merge one branch into another". However, the original question is more specific and special case than the title would suggest.
It is also more complex than both the subject and the search expression. As such, this is a minimal but explanatory answer for the benefit of most visitors.

In my case, even after sign up to Visual Studio account, I cant sign in and the license still expired.

Solution from across the internet: Download iso version of the installer. Then run installer, select repair. That would solve the problem for most case.

In my case, I got an iso version of ms Visual Studio 2013. Installed it and I can successfully sign in and its forever free.

That is a unicode character code that, when parsed by JavaScript as a string, is converted into its corresponding character (JavaScript automatically converts any occurrences of \uXXXX into the corresponding Unicode character). For example, your example would be:

Browse Interests{{/i}}</a>\n        </li>\n  {{#logged_in}}\n

As you can see, \u003C changes into < (less-than sign) and \u003E changes into > (greater-than sign).

In addition to the link posted by Raynos, this page from the Unicode website lists a lot of characters (so many that they decided to annoyingly group them) and this page has a (kind of) nice index.

If you want that in Angular 2 or Angular 4 and also want to keep inline CSS then you can use

<div [innerHTML]="theHtmlString | keepHtml"></div>

The color of the buttons and other text can also be changed via theme:

values-21/styles.xml

<style name="AppTheme" parent="...">
  ...
  <item name="android:timePickerDialogTheme">@style/AlertDialogCustom</item>
  <item name="android:datePickerDialogTheme">@style/AlertDialogCustom</item>
  <item name="android:alertDialogTheme">@style/AlertDialogCustom</item>
</style>

<style name="AlertDialogCustom" parent="android:Theme.Material.Light.Dialog.Alert">
  <item name="android:colorPrimary">#00397F</item>
  <item name="android:colorAccent">#0AAEEF</item>
</style>

The result:

This function works in at least Firefox, and Internet Explorer. It runs any event handlers attached to the link and loads the linked page if the event handlers don't cancel the default action.

function clickLink(link) {
    var cancelled = false;

    if (document.createEvent) {
        var event = document.createEvent("MouseEvents");
        event.initMouseEvent("click", true, true, window,
            0, 0, 0, 0, 0,
            false, false, false, false,
            0, null);
        cancelled = !link.dispatchEvent(event);
    }
    else if (link.fireEvent) {
        cancelled = !link.fireEvent("onclick");
    }

    if (!cancelled) {
        window.location = link.href;
    }
}

Mindless passenger has a project that allows for multiple results sets to be returned from a stored proc using entity framework. One of his examples below....

using (testentities te = new testentities())
{
    //-------------------------------------------------------------
    // Simple stored proc
    //-------------------------------------------------------------
    var parms1 = new testone() { inparm = "abcd" };
    var results1 = te.CallStoredProc<testone>(te.testoneproc, parms1);
    var r1 = results1.ToList<TestOneResultSet>();
}

PHP 7.4+; with the null coalescing assignment operator

$var ??= '';

PHP 7.0+; with the null coalescing operator

$var = $var ?? '';

PHP 5.3+; with the ternary operator shorthand

isset($var) ?: $var = '';

Or for all/older versions with isset:

$var = isset($var) ? $var : '';

or

!isset($var) && $var = '';

It is common to have components that are only rendering from props. Like this:

class Template extends React.Component{
  render (){
    return <div>this.props.something</div>
  }
}

Then in your upper level component where you have the logic you just import the Template component and pass the needed props. All your logic stays in the higher level component, and the Template only renders. This is a possible way to achieve 'templates' like in Angular.

There is no way to have .jsx file with jsx only and use it in React because jsx is not really html but markup for a virtual DOM, which React manages.

My reset.css was margin: 0, padding: 0. After several hours of looking and troubleshooting this worked:

li {
    list-style: disc outside none;
    margin-left: 1em;
}

ul {
    margin: 1em;
}

select into is used in pl/sql to set a variable to field values. Instead, use

create table new_table as select * from old_table

Here's the real solution (with other cool CSS3 stuff):

#fixed-square {
position: fixed;
top: 0;
right: 0;
z-index: 9500;
cursor: pointer;
width: 24px;
padding: 18px 18px 14px;
opacity: 0.618;
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
transform: rotate(-90deg);
-webkit-transition: all 0.145s ease-out;
-moz-transition: all 0.145s ease-out;
-ms-transition: all 0.145s ease-out;
transition: all 0.145s ease-out;
}

Note the top:0 and right:0. That's what did it for me.

What about this? Change the return type from T to Nullable<T>

public static Nullable<T> GetQueryString<T>(string key) where T : struct, IConvertible
        {
            T result = default(T);

            if (String.IsNullOrEmpty(HttpContext.Current.Request.QueryString[key]) == false)
            {
                string value = HttpContext.Current.Request.QueryString[key];

                try
                {
                    result = (T)Convert.ChangeType(value, typeof(T));  
                }
                catch
                {
                    //Could not convert.  Pass back default value...
                    result = default(T);
                }
            }

            return result;
        }

You can actually handle all of this with just a simple template tag. See http://jsfiddle.net/m4ve9/ for an example. Note that I actually didn't need a compile or link property on the super-directive definition.

During the compilation process, Angular pulls in the template values before compiling, so you can attach any further directives there and Angular will take care of it for you.

If this is a super directive that needs to preserve the original internal content, you can use transclude : true and replace the inside with <ng-transclude></ng-transclude>

Hope that helps, let me know if anything is unclear

Alex

If you want to be a little bit fancier you can also create it as an html list to create something like bullets or numbers using ul or ol.

<ul>
<li>Line 1</li>
<li>Line 2</li>
</ul>

For me, in VS 2013, I had to get rid of missing references under References in the UI project (MVC). Turns out, the ones missing were not referenced.

Daniel's answer is probably the most ideal one as it doesn't involve changing OS files. However, I found myself in a situation where I needed a 3rd party program which invoked python by calling usr/bin/python, but required Python 2.7.16, while the default Python was 2.7.5. That meant I had to make usr/bin/python point to a Python version of 2.7.16 version, which meant that yum wouldn't work.

What I ended up doing is editing the file /usr/bin/yum and replacing the shebang there to use to the system default Python (in my case, that meant changing #! /usr/bin/python to #! /usr/bin/python2). However, after that running yum gave me an error:

ImportError: No module named urlgrabber.grabber

I solved that by replacing the shebang in /usr/libexec/urlgrabber-ext-down the same way as in /usr/bin/yum. I.e., #! /usr/bin/python to #! /usr/bin/python2. After that yum worked.

This is a hack and should be used with care. As mentioned in other comments, modifying OS files should be last resort only.

For Kotlin:

Just create a new file with name URIPathHelper.kt. Then copy and paste the following Utility class in your file. It covers all scenarios and works perfectly for all Android versions. Its explanation will be discussed later.

How to Use URIPathHelper class to get path from URI

val uriPathHelper = URIPathHelper()
val filePath = uriPathHelper.getPath(this, YOUR_URI_OBJECT)

It means a call to a virtual function will be forwarded to the "right" class.

C++ FAQ Lite FTW.

In short, it is often used in multiple-inheritance scenarios, where a "diamond" hierarchy is formed. Virtual inheritance will then break the ambiguity created in the bottom class, when you call function in that class and the function needs to be resolved to either class D1 or D2 above that bottom class. See the FAQ item for a diagram and details.

It is also used in sister delegation, a powerful feature (though not for the faint of heart). See this FAQ.

Also see Item 40 in Effective C++ 3rd edition (43 in 2nd edition).

IMPORTANT NOTE: You have to sort your data first.

The part I didn't get is that in the example construction

groups = []
uniquekeys = []
for k, g in groupby(data, keyfunc):
   groups.append(list(g))    # Store group iterator as a list
   uniquekeys.append(k)

k is the current grouping key, and g is an iterator that you can use to iterate over the group defined by that grouping key. In other words, the groupby iterator itself returns iterators.

Here's an example of that, using clearer variable names:

from itertools import groupby

things = [("animal", "bear"), ("animal", "duck"), ("plant", "cactus"), ("vehicle", "speed boat"), ("vehicle", "school bus")]

for key, group in groupby(things, lambda x: x[0]):
    for thing in group:
        print("A %s is a %s." % (thing[1], key))
    print("")
    

This will give you the output:

A bear is a animal.
A duck is a animal.

A cactus is a plant.

A speed boat is a vehicle.
A school bus is a vehicle.

In this example, things is a list of tuples where the first item in each tuple is the group the second item belongs to.

The groupby() function takes two arguments: (1) the data to group and (2) the function to group it with.

Here, lambda x: x[0] tells groupby() to use the first item in each tuple as the grouping key.

In the above for statement, groupby returns three (key, group iterator) pairs - once for each unique key. You can use the returned iterator to iterate over each individual item in that group.

Here's a slightly different example with the same data, using a list comprehension:

for key, group in groupby(things, lambda x: x[0]):
    listOfThings = " and ".join([thing[1] for thing in group])
    print(key + "s:  " + listOfThings + ".")

This will give you the output:

animals: bear and duck.
plants: cactus.
vehicles: speed boat and school bus.

render() {
  return (
    <View style={...}>
       {initialArr.map((prop, key) => {
         return (
           <Button style={{borderColor: prop[0]}}  key={key}>{prop[1]}</Button>
         );
      })}
     </View>
  )
}

should do the trick

Well I'll begin with the second question: What are Web Services? , for obvious reasons.

WebServices are essentially pieces of logic(which you may vaguely refer to as a method) that expose certain functionality or data. The client implementing(technically speaking, consuming is the word) just needs to know what are the parameter(s) the method is going to accept and the type of data it is going to return(if at all it does).

The following Link says it all about REST & SOAP in an extremely lucid manner.

REST vs SOAP

If you also want to know when to choose what (REST or SOAP), all the more reason to go through it!

I wanted to horizontally align 5 images, so I ended up following Mete's response with a small difference.

The first image will be centered horizontally in container equal to 0 and a multiplier of 1:5:

The second image will be centered horizontally in container equal to 0 and a multiplier of 3:5:

And like that for the rest of the images. For example, the fifth (and last) image will be centered horizontally in container equal to 0 and a multiplier of 9:5:

As Mete explained, the order goes 1, 3, 5, 7, 9, etc. The positions follow the same logic: the first position is 1, then space, then the next position 3, and so on.

It could be something like:

var qry = from t in db.Lasttraces
          group t by t.AccountId into g
          orderby t.Date
          select new { g.AccountId, Date = g.Max(e => e.Date) };

Without the need to install the grep variant pcregrep, you can do multiline search with grep.

$ grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.c

Explanation:

-P activate perl-regexp for grep (a powerful extension of regular expressions)

-z suppress newline at the end of line, substituting it for null character. That is, grep knows where end of line is, but sees the input as one big line.

-o print only matching. Because we're using -z, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.

In regexp:

(?s) activate PCRE_DOTALL, which means that . finds any character or newline

\N find anything except newline, even with PCRE_DOTALL activated

.*? find . in non-greedy mode, that is, stops as soon as possible.

^ find start of line

\1 backreference to the first group (\s*). This is a try to find the same indentation of method.

As you can imagine, this search prints the main method in a C (*.c) source file.

SELECT TO_CHAR(created_at, 'YYYY-MM-DD') FROM table; //converts any date format to YYYY-MM-DD

Verify your code with JSLint. It will usually find a ton of small errors, so the warning "JSLint may hurt your feelings" is pretty spot on. =)

You can also make additions to this path with the PYTHONPATH environment variable at runtime, in addition to:

import sys
sys.path.append('/home/user/python-libs')

If I understand correct you will have something like this:

<input value="default" id="sth" name="sth" type="hidden">

And to get it you have to write:

@Html.HiddenFor(m => m.sth, new { Value = "default" })

for Strongly-typed view.

On modern CMake (>= 3.1) the best way to set global requirements is:

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

It translates to "I want C++11 for all targets, it's not optional, I don’t want to use any GNU or Microsoft extensions." As of C++17, this still is IMHO the best way.

You don't mention if this is an anonymous PL/SQL block or a declarative one ie. Package, Procedure or Function. However, in PL/SQL a COMMIT must be explicitly made to save your transaction(s) to the database. The COMMIT actually saves all unsaved transactions to the database from your current user's session.

If an error occurs the transaction implicitly does a ROLLBACK.

This is the default behaviour for PL/SQL.

Very informally:

A POD is a type (including classes) where the C++ compiler guarantees that there will be no "magic" going on in the structure: for example hidden pointers to vtables, offsets that get applied to the address when it is cast to other types (at least if the target's POD too), constructors, or destructors. Roughly speaking, a type is a POD when the only things in it are built-in types and combinations of them. The result is something that "acts like" a C type.

Less informally:

• int, char, wchar_t, bool, float, double are PODs, as are long/short and signed/unsigned versions of them.
• pointers (including pointer-to-function and pointer-to-member) are PODs,
• enums are PODs
• a const or volatile POD is a POD.
• a class, struct or union of PODs is a POD provided that all non-static data members are public, and it has no base class and no constructors, destructors, or virtual methods. Static members don't stop something being a POD under this rule. This rule has changed in C++11 and certain private members are allowed: Can a class with all private members be a POD class?
• Wikipedia is wrong to say that a POD cannot have members of type pointer-to-member. Or rather, it's correct for the C++98 wording, but TC1 made explicit that pointers-to-member are POD.

Formally (C++03 Standard):

3.9(10): "Arithmetic types (3.9.1), enumeration types, pointer types, and pointer to member types (3.9.2) and cv-qualified versions of these types (3.9.3) are collectively caller scalar types. Scalar types, POD-struct types, POD-union types (clause 9), arrays of such types and cv-qualified versions of these types (3.9.3) are collectively called POD types"

9(4): "A POD-struct is an aggregate class that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-define copy operator and no user-defined destructor. Similarly a POD-union is an aggregate union that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-define copy operator and no user-defined destructor.

8.5.1(1): "An aggregate is an array or class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10) and no virtual functions (10.3)."

We wrote a wrapper class that captures the buffer and converts the printed output to an exception. this lets us upgrade the phpmailer file without having to remember to comment out the echo statements each time we upgrade.

The wrapper class has methods something along the lines of:

public function AddAddress($email, $name = null) {
    ob_start();
    parent::AddAddress($email, $name);
    $error = ob_get_contents();
    ob_end_clean();
    if( !empty($error) ) {
        throw new Exception($error);
    }
}

Loop through and print all the values of an associative array, you could use a foreach loop, like this:

foreach($results as $x => $value) {
    echo $value;
}

Change your onCreate to

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

for me this update worked

Assuming you want to read from resources directory in FileSystem class.

String file = "dummy.txt";
var path = Paths.get("src/com/company/fs/resources/", file);
System.out.println(path);

System.out.println(Files.readString(path));

Note: Leading . is not needed.

One alternative missing from other answers is that you can go the other way around: define your method in your Controller, and then use helper_method to make it also available on views as, you know, a helper method.

For instance:

class ApplicationController < ActionController::Base

private

  def something_count
    # All other controllers that inherit from ApplicationController will be able to call `something_count`
  end
  # All views will be able to call `something_count` as well
  helper_method :something_count 

end

You can remove flutter and "install again", so fastest way is to:

1) Check where you have flutter (as executable)

To check it, you can run:

which flutter

And you can expect such output:

/your_user/your_path/flutter/bin/flutter

2) Go to this directory

Above path is directly to flutter, but we would like to go to directory so "one earlier" in path:

cd /your_user/your_path/flutter/bin

3) Check is it git repository

It should be, but it's worth to check.

Run one of the git command e.g.

git status

or

git branch

When it's git repository you will receive some info about it or correct list of branches.

4) Remove all of the files

rm -R *

5) "revert" removal to have only necessary files:

git co -- .

6) Voila!

You can run just flutter version and commands should work (and Flutter will fetch some necessary data).

You want to use URI templates. Look carefully at the README of this project: URLEncoder.encode() does NOT work for URIs.

Let us take your original URL:

http://site-test.test.com/Meetings/IC/DownloadDocument?meetingId=c21c905c-8359-4bd6-b864-844709e05754&itemId=a4b724d1-282e-4b36-9d16-d619a807ba67&file=\s604132shvw140\Test-Documents\c21c905c-8359-4bd6-b864-844709e05754_attachments\7e89c3cb-ce53-4a04-a9ee-1a584e157987\myDoc.pdf

and convert it to a URI template with two variables (on multiple lines for clarity):

http://site-test.test.com/Meetings/IC/DownloadDocument
    ?meetingId={meetingID}&itemId={itemID}&file={file}

Now let us build a variable map with these three variables using the library mentioned in the link:

final VariableMap = VariableMap.newBuilder()
    .addScalarValue("meetingID", "c21c905c-8359-4bd6-b864-844709e05754")
    .addScalarValue("itemID", "a4b724d1-282e-4b36-9d16-d619a807ba67e")
    .addScalarValue("file", "\\\\s604132shvw140\\Test-Documents"
        + "\\c21c905c-8359-4bd6-b864-844709e05754_attachments"
        + "\\7e89c3cb-ce53-4a04-a9ee-1a584e157987\\myDoc.pdf")
    .build();

final URITemplate template
    = new URITemplate("http://site-test.test.com/Meetings/IC/DownloadDocument"
        + "meetingId={meetingID}&itemId={itemID}&file={file}");

// Generate URL as a String
final String theURL = template.expand(vars);

This is GUARANTEED to return a fully functional URL!

Your route isn't ok, it should be like this (with ':')

app.get('/documents/:format/:type', function (req, res) {
   var format = req.params.format,
       type = req.params.type;
});

Also you cannot interchange parameter order unfortunately. For more information on req.params (and req.query) check out the api reference here.

You can set timeout like this,

con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);

To share some analysis info. With a simple test how long it takes to read ~1180 lines of values.

If you need to read the data very fast, use the good old BufferedReader FileReader example. It took me ~8ms

The Scanner is much slower. Took me ~138ms

The nice Java 8 Files.lines(...) is the slowest version. Took me ~388ms.

You could try the following code. I can't vouch for browser compatibility though, so you'll have to test that.

function testImage(URL) {
    var tester=new Image();
    tester.onload=imageFound;
    tester.onerror=imageNotFound;
    tester.src=URL;
}

function imageFound() {
    alert('That image is found and loaded');
}

function imageNotFound() {
    alert('That image was not found.');
}

testImage("http://foo.com/bar.jpg");

And my sympathies for the jQuery-resistant boss!

You can use shared preferences from flutter's official plugins. https://github.com/flutter/plugins/tree/master/packages/shared_preferences

It uses Shared Preferences for Android, NSUserDefaults for iOS.

Existing solution

The shortest and probably the fastest solution is:

from math import factorial
print factorial(1000)

Building your own

You can also build your own solution. Generally you have two approaches. The one that suits me best is:

from itertools import imap
def factorial(x):
    return reduce(long.__mul__, imap(long, xrange(1, x + 1)))

print factorial(1000)

(it works also for bigger numbers, when the result becomes long)

The second way of achieving the same is:

def factorial(x):
    result = 1
    for i in xrange(2, x + 1):
        result *= i
    return result

print factorial(1000)

Demo

You have two options here, you can make it open in a new window/tab with JS:

<td onClick={()=> window.open("someLink", "_blank")}>text</td>

But a better option is to use a regular link but style it as a table cell:

<a style={{display: "table-cell"}} href="someLink" target="_blank">text</a>

My proposal without ugly "foreach" control structures is

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));
$allFiles = array_filter(iterator_to_array($iterator), function($file) {
    return $file->isFile();
});

You may only want to extract the filepath, which you can do so by:

array_keys($allFiles);

Still 4 lines of code, but more straight forward than using a loop or something.

int.TryParse()

It won't throw if the text is not numeric.

sed -e '/^ *$/d' input > output

Deletes all lines which consist only of blanks (or is completely empty). You can change the blank to [ \t] where the \t is a representation for tab. Whether your shell or your sed will do the expansion varies, but you can probably type the tab character directly. And if you're using GNU or BSD sed, you can do the edit in-place, if that's what you want, with the -i option.

If I execute the above command still I have blank lines in my output file. What could be the reason?

There could be several reasons. It might be that you don't have blank lines but you have lots of spaces at the end of a line so it looks like you have blank lines when you cat the file to the screen. If that's the problem, then:

sed -e 's/  *$//' -e '/^ *$/d' input > output

The new regex removes repeated blanks at the end of the line; see previous discussion for blanks or tabs.

Another possibility is that your data file came from Windows and has CRLF line endings. Unix sees the carriage return at the end of the line; it isn't a blank, so the line is not removed. There are multiple ways to deal with that. A reliable one is tr to delete (-d) character code octal 15, aka control-M or \r or carriage return:

tr -d '\015' < input | sed -e 's/  *$//' -e '/^ *$/d' > output

If neither of those works, then you need to show a hex dump or octal dump (od -c) of the first two lines of the file, so we can see what we're up against:

head -n 2 input | od -c

Judging from the comments that sed -i does not work for you, you are not working on Linux or Mac OS X or BSD — which platform are you working on? (AIX, Solaris, HP-UX spring to mind as relatively plausible possibilities, but there are plenty of other less plausible ones too.)

You can try the POSIX named character classes such as sed -e '/^[[:space:]]*$/d'; it will probably work, but is not guaranteed. You can try it with:

echo "Hello World" | sed 's/[[:space:]][[:space:]]*/   /'

If it works, there'll be three spaces between the 'Hello' and the 'World'. If not, you'll probably get an error from sed. That might save you grief over getting tabs typed on the command line.

There are one solution for fake GPS in ios simulator and real device. we can use GPX file for fake GPS and simulation.

I followed the step by step guidelines of GPX file use in Xcode with simulation. Here is full step by step guidelines of GPX file use. And also you can download the GPX file Demo from github.

It is also possible to round negative integers

// performing d = c * 3/4 where d can be pos or neg
d = ((c * a) + ((c>0? (b>>1):-(b>>1)))) / b;
// explanation:
// 1.) multiply:          c * a  
// 2.) if c is negative:  (c>0? subtract half of the dividend 
//                              (b>>1) is bit shift right = (b/2)
//     if c is positive:  else  add half of the dividend 
// 3.) do the division
// on a C51/52 (8bit embedded) or similar like ATmega the below code may execute in approx 12cpu cycles (not tested)

Extended from a tip somewhere else in here. Sorry, missed from where.

/* Example test: integer rounding example including negative*/
#include <stdio.h>
#include <string.h>

int main () {
   //rounding negative int
   // doing something like d = c * 3/4
   int a=3;
   int b=4;
   int c=-5;
   int d;
   int s=c;
   int e=c+10;


   for(int f=s; f<=e; f++) {
      printf("%d\t",f);

      double cd=f, ad=a, bd=b , dd;

      // d = c * 3/4  with double
      dd = cd * ad / bd;

      printf("%.2f\t",dd);
      printf("%.1f\t",dd);        
      printf("%.0f\t",dd);

      // try again with typecast have used that a lot in Borland C++ 35 years ago....... maybe evolution has overtaken it ;) ***
      // doing div before mul on purpose
      dd =(double)c * ((double)a / (double)b);
      printf("%.2f\t",dd);

      c=f;
      // d = c * 3/4  with integer rounding
      d = ((c * a) + ((c>0? (b>>1):-(b>>1)))) / b;
      printf("%d\t",d);
      puts("");
  }
 return 0;
}

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.
