here is what you should put

local stringnumber = "10"
local a = tonumber(stringnumber)
print(a + 10)

output:

20

I faced the same issue, spent too much calories searching for the right fix until I decided to settle down with file reading:

Properties configProps = new Properties();
InputStream iStream = new ClassPathResource("myapp-test.properties").getInputStream();
InputStream iStream = getConfigFile();
configProps.load(iStream);

Try putting a space before each \;

Works:

find . -name "*.log" -exec echo {} \;

Doesn't Work:

find . -name "*.log" -exec echo {}\;

Piggy-backing off of VIKAS KOHLI and jedmao, you can do this

single line version:

npm uninstall `ls -1 node_modules | grep -v ^@ | tr '/\n' ' '` `find node_modules/@* -type d -depth 1 2>/dev/null | cut -d/ -f2-3 | tr '\n' ' '`

multi-lined version:

npm uninstall \
`ls -1 node_modules | grep -v ^@ | tr '/\n' ' '` \
`find node_modules/@* -type d -depth 1 2>/dev/null | cut -d/ -f2-3 | tr '\n' ' '`

Check the Java API for List.
The get(int index) method is declared to throw only the IndexOutOfBoundException which extends RuntimeException.
You are trying to tell Mockito to throw an exception SomeException() that is not valid to be thrown by that particular method call.

To clarify further.
The List interface does not provide for a checked Exception to be thrown from the get(int index) method and that is why Mockito is failing.
When you create the mocked List, Mockito will use the definition of List.class to creates its mock.

The behavior you are specifying with the when(list.get(0)).thenThrow(new SomeException()) doesn't match the method signature in List API, because get(int index) method does not throw SomeException() so Mockito fails.

If you really want to do this, then have Mockito throw a new RuntimeException() or even better throw a new ArrayIndexOutOfBoundsException() since the API specifies that that is the only valid Exception to be thrown.

Use the DO statement, a new option in version 9.0:

DO LANGUAGE plpgsql

I recommend using com.fasterxml.jackson.databind.ObjectMapper (Maven repo link: https://mvnrepository.com/artifact/com.fasterxml.jackson.core) like

final ObjectMapper mapper = new ObjectMapper();
Map<String, Object> mapFromString = new HashMap<>();
try {
    mapFromString = mapper.readValue(theStringToParse, new TypeReference<Map<String, Object>>() {
        });
} catch (IOException e) {
    LOG.error("Exception launched while trying to parse String to Map.", e);
}

String myFormat= "yyyy-MM-dd";
String finalString = "";
try {
DateFormat formatter = new SimpleDateFormat("yyyy MMM dd");
Date date = (Date) formatter .parse("2015 Oct 09");
SimpleDateFormat newFormat = new SimpleDateFormat(myFormat);
finalString= newFormat .format(date );
newDate.setText(finalString);
} catch (Exception e) {

}

Try this regular expression:

\b(\w+)\s+\1\b

Here \b is a word boundary and \1 references the captured match of the first group.

The questioner actually asked about int16 (etc) rather than (ugly) int16_t (etc).

There are no standard headers - nor any in Linux's /usr/include/ folder that define them without the "_t".

I know this is an old thread but it was the first I found when searching. The += solution did not work for me. The code that I did get to work is as below.

#this bit creates the CSV if it does not already exist
$headers = "Name", "Primary Type"
$psObject = New-Object psobject
foreach($header in $headers)
{
 Add-Member -InputObject $psobject -MemberType noteproperty -Name $header -Value ""
}
$psObject | Export-Csv $csvfile -NoTypeInformation

#this bit appends a new row to the CSV file
$bName = "My Name"
$bPrimaryType = "My Primary Type"
    $hash = @{
             "Name" =  $bName
             "Primary Type" = $bPrimaryType
              }

$newRow = New-Object PsObject -Property $hash
Export-Csv $csvfile -inputobject $newrow -append -Force

I was able to use this as a function to loop through a series of arrays and enter the contents into the CSV file.

It works in powershell 3 and above.

If you want to stop Git from always asking you for the login credentials of your GitHub repository this can be easily done.

Using SSH instead of HTTPS

You can update the origin remote using SSH instead of HTTPS"

git remote set-url origin [email protected]:username/your-repo.git

Configure Git to Store your Password and Username

Here’s how you can make Git store the username and password:

git config --global credential.helper store

Next, save the username and password for a session:

git config --global credential.helper cache

I had to remove .idea and target folders and after reading all comments this worked for me:

git rm -r .idea
git rm -r target
git commit -m 'removed .idea folder'

and then push to master

You have a date with a known timezone (Here Europe/Madrid), and a target timezone (UTC)

You just need two SimpleDateFormats:

        long ts = System.currentTimeMillis();
        Date localTime = new Date(ts);

        SimpleDateFormat sdfLocal = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss");
        sdfLocal.setTimeZone(TimeZone.getTimeZone("Europe/Madrid"));

        SimpleDateFormat sdfUTC = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss");
        sdfUTC.setTimeZone(TimeZone.getTimeZone("UTC"));

        // Convert Local Time to UTC
        Date utcTime = sdfLocal.parse(sdfUTC.format(localTime));
        System.out.println("Local:" + localTime.toString() + "," + localTime.getTime() + " --> UTC time:" + utcTime.toString() + "-" + utcTime.getTime());

        // Reverse Convert UTC Time to Locale time
        localTime = sdfUTC.parse(sdfLocal.format(utcTime));
        System.out.println("UTC:" + utcTime.toString() + "," + utcTime.getTime() + " --> Local time:" + localTime.toString() + "-" + localTime.getTime());

So after see it working you can add this method to your utils:

    public Date convertDate(Date dateFrom, String fromTimeZone, String toTimeZone) throws ParseException {
        String pattern = "yyyy/MM/dd HH:mm:ss";
        SimpleDateFormat sdfFrom = new SimpleDateFormat (pattern);
        sdfFrom.setTimeZone(TimeZone.getTimeZone(fromTimeZone));

        SimpleDateFormat sdfTo = new SimpleDateFormat (pattern);
        sdfTo.setTimeZone(TimeZone.getTimeZone(toTimeZone));

        Date dateTo = sdfFrom.parse(sdfTo.format(dateFrom));
        return dateTo;
    }

If you are using PHP >= 7.2 consider using inbuilt sodium core extension for encrption.

Find more information here - http://php.net/manual/en/intro.sodium.php.

Simply the answer according to my reading and understanding to this thread and @remus-rusanu answer is based on this simple scenario:

There are two transactions A and B. Transaction B is reading Table X Transaction A is writing in table X Transaction B is reading again in Table X.

• ReadUncommitted: Transaction B can read uncommitted data from Transaction A and it could see different rows based on B writing. No lock at all
• ReadCommitted: Transaction B can read ONLY committed data from Transaction A and it could see different rows based on COMMITTED only B writing. could we call it Simple Lock?
• RepeatableRead: Transaction B will read the same data (rows) whatever Transaction A is doing. But Transaction A can change other rows. Rows level Block
• Serialisable: Transaction B will read the same rows as before and Transaction A cannot read or write in the table. Table-level Block
• Snapshot: every Transaction has its own copy and they are working on it. Each one has its own view

If you make change default value to CURRENT_TIMESTAMP it is more effiency,

ALTER TABLE servers MODIFY COLUMN network_shares datetime NOT NULL DEFAULT CURRENT_TIMESTAMP;

You can do this by using JQuery.

For example ,

<a href="your URL" id="navigate"> click here </a>

Your JQuery will be,

$(document).ready(function(){

    $('a').on('mousedown', stopNavigate);

    $('a').on('mouseleave', function () {
           $(window).on('beforeunload', function(){
                  return 'Are you sure you want to leave?';
           });
    });
});

function stopNavigate(){    
    $(window).off('beforeunload');
}

And to get the Leave message alert will be,

$(window).on('beforeunload', function(){
      return 'Are you sure you want to leave?';
});

$(window).on('unload', function(){

         logout();

});

This solution works in all browsers and I have tested it.

I ran into this very problem trying to send mail with javax.mail from a web application in a web server running Java 7. Internal mail server destinations failed with "network unreachable", despite telnet and ping working from the same host, and while external mail servers worked. I tried

System.setProperty("java.net.preferIPv4Stack" , "true");

in the code, but that failed. So the parameter value was probably cached earlier by the system. Setting the VM argument

-Djava.net.preferIPv4Stack=true

in the web server startup script worked.

One further bit of evidence: in a very small targeted test program, setting the system property in the code did work. So the parameter is probably cached when the first Socket is used, probably not just as the JVM starts.

If cleaning the solution didn't work and for anybody who see's this question and tried moving a project or renaming.

Open Package manager console and type "dotnet restore".

Unfortunately to be able to use the extension modules provided by others you'll be forced to use the official compiler to compile Python. These are:

• Visual Studio 2008 for Python 2.7. See: https://docs.python.org/2.7/using/windows.html#compiling-python-on-windows

• Visual Studio 2010 for Python 3.4. See: https://docs.python.org/3.4/using/windows.html#compiling-python-on-windows

Alternatively, you can use MinGw to compile extensions in a way that won't depend on others.

See: https://docs.python.org/2/install/#gnu-c-cygwin-MinGW or https://docs.python.org/3.4/install/#gnu-c-cygwin-mingw

This allows you to have one compiler to build your extensions for both versions of Python, Python 2.x and Python 3.x.

Model (App\Post.php):

/**
 * Get all comments for this post.
 */
public function comments($published = false)
{
    $comments = $this->hasMany('App\Comment');
    if($published) $comments->where('published', 1);

    return $comments;
}

Controller (App\Http\Controllers\PostController.php):

/**
 * Display the specified resource.
 *
 * @param int $id
 * @return \Illuminate\Http\Response
 */
public function post($id)
{
    $post = Post::with('comments')
        ->find($id);

    return view('posts')->with('post', $post);
}

Blade template (posts.blade.php):

{{-- Get all comments--}}
@foreach ($post->comments as $comment)
    code...
@endforeach

{{-- Get only published comments--}}
@foreach ($post->comments(true)->get() as $comment)
    code...
@endforeach

When I run your code, I get the following output for example.

<usb.Device object at 0xef38c0>
Device: 001
  idVendor: 7531 (0x1d6b)
  idProduct: 1 (0x0001)
Manufacturer: 3
Serial: 1
Product: 2

Noteworthy are that a) I have usb.Device objects whereas you have usb.legacy.Device objects, and b) I have device filenames.

Each usb.Bus has a dirname field and each usb.Device has the filename. As you can see, the filename is something like 001, and so is the dirname. You can combine these to get the bus file. For dirname=001 and filname=001, it should be something like /dev/bus/usb/001/001.

You should first, though figure out what this "usb.legacy" situation is. I'm running the latest version and I don't even have a legacy sub-module.

Finally, you should use the idVendor and idProduct fields to uniquely identify the device when it's plugged in.

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

You need to edit your hosts file on your Windows Virtual machine the same way you do for your local host machine:

C:\WINDOWS\system32\drivers\etc\hosts

And link your virtual hosts to 10.0.2.2, If you are just using localhost then replace

127.0.0.1 localhost with 10.0.2.2 localhost

For example:

10.0.2.2 localhost
10.0.2.2 local.site1.com
10.0.2.2 local.site2.com

This tells your virtual machine to point to your local machine for those domain names.

I found that using cast() was the best solution for me:

cast(Format(amount, "Standard") AS CHAR CHARACTER SET utf8) AS Amount

There is also a convert() function. More details on it here

Use this code, it will surely work:

<script type="text/javascript">_x000D_
 $(document).ready(function () {_x000D_
  setTimeout(function(){_x000D_
   downloadImage();_x000D_
  },1000)_x000D_
 });_x000D_
 _x000D_
 function downloadImage(){_x000D_
  html2canvas(document.querySelector("#dvContainer")).then(canvas => {_x000D_
  a = document.createElement('a'); _x000D_
  document.body.appendChild(a); _x000D_
  a.download = "test.png"; _x000D_
  a.href =  canvas.toDataURL();_x000D_
  a.click();_x000D_
 });  _x000D_
 }_x000D_
</script>

Just do not forget to include Html2CanvasJS file in your program. https://html2canvas.hertzen.com/dist/html2canvas.js

Execute something similar to the following command:

aws s3 cp local_folder_name s3://s3_bucket_name/local_folder_name/ --recursive

Sorry to revive an old thread but should anyone be looking for an alternative solution where you store your string lists as one field in your database, here's how I solved that. Create a Converter like this:

import java.util.Arrays;
import java.util.List;

import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

import static java.util.Collections.*;

@Converter
public class StringListConverter implements AttributeConverter<List<String>, String> {
    private static final String SPLIT_CHAR = ";";
    
    @Override
    public String convertToDatabaseColumn(List<String> stringList) {
        return stringList != null ? String.join(SPLIT_CHAR, stringList) : "";
    }

    @Override
    public List<String> convertToEntityAttribute(String string) {
        return string != null ? Arrays.asList(string.split(SPLIT_CHAR)) : emptyList();
    }
}

Now use it on your Entities like this:

@Convert(converter = StringListConverter.class)
private List<String> yourList;

In the database, your list will be stored as foo;bar;foobar, and in your Java object you will get a list with those strings.

Hope this is helpful to someone.

Your question contains the string literal "\b[A-Z]{2,}\b", but that \b will mean backspace, because there is no r-modifier.

Try: r"\b[A-Z]{2,}\b".

There are a bunch of color descriptors used to recognise objects, the paper below compares a lot of them. They are specially powerful when combined with SIFT or SURF. SURF or SIFT alone are not very useful in a coca cola can image because they don't recognise a lot of interest points, you need the color information to help. I use BIC (Border/Interior Pixel Classi?cation) with SURF in a project and it worked great to recognise objects.

Color descriptors for Web image retrieval: a comparative study

In DOS you couldn't use environment variables on the command line, only in batch files, where they used the % sign as a delimiter. If you wanted a literal % sign in a batch file, e.g. in an echo statement, you needed to double it.

This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your % signs in a .cmd file.

WinForm:

private void button1_Click(object sender, EventArgs e)
{
   button2.BackColor = Color.Red;
}

WPF:

private void button1_Click(object sender, RoutedEventArgs e)
{
   button2.Background = Brushes.Blue;
}

You can use this with replacement of CGRectZero

CGRect.zero

Confining Mutability to Builders

The top answers here correctly speak to the difference in Kotlin between read-only List (NOTE: it's read-only, not "immutable"), and MutableList.

In general, one should strive to use read-only lists, however, mutability is still often useful at construction time, especially when dealing with third-party libraries with non-functional interfaces. For cases in which alternate construction techniques are not available, such as using listOf directly, or applying a functional construct like fold or reduce, a simple "builder function" construct like the following nicely produces a read-only list from a temporary mutable one:

val readonlyList = mutableListOf<...>().apply {
  // manipulate your list here using whatever logic you need
  // the `apply` function sets `this` to the `MutableList`
  add(foo1)
  addAll(foos)
  // etc.
}.toList()

and this can be nicely encapsulated into a re-usable inline utility function:

inline fun <T> buildList(block: MutableList<T>.() -> Unit) = 
  mutableListOf<T>().apply(block).toList()

which can be called like this:

val readonlyList = buildList<String> {
  add("foo")
  add("bar")
}

Now, all of the mutability is isolated to one block scope used for construction of the read-only list, and the rest of your code uses the read-only list that is output from the builder.

UPDATE: As of Kotlin 1.3.70, the exact buildList function above is available in the standard library as an experimental function, along with its analogues buildSet and buildMap. See https://blog.jetbrains.com/kotlin/2020/03/kotlin-1-3-70-released/.

Notepad++ will only auto-insert subsequent indents if you manually indent the first line in a block; otherwise you can re-indent your code after the fact using TextFX > TextFX Edit > Reindent C++ code.

Really this is an extension to Marcin's answer.

But you could also try passing "rubbish" arguments to see if you get any errors back. Getting any response from the executable directly in the shell will mean that it is likely looking at the arguments you're passing, with an error response being close to a guarantee that it is.

Failing that you might have to directly ask the publishers/creators/owners... sniffing the binaries yourself just seems like far too much work for an end-user.

Sometimes using   instead of spaces will work. Clearly it has drawbacks, though.

Just inject the routeParams service:

http://docs.angularjs.org/api/ngRoute.$routeParams

Use select setval('payments_id_seq', 21, true);

setval contains 3 parameters:

• 1st parameter is sequence_name
• 2nd parameter is Next nextval
• 3rd parameter is optional.

The use of true or false in 3rd parameter of setval is as follows:

SELECT setval('payments_id_seq', 21);           // Next nextval will return 22
SELECT setval('payments_id_seq', 21, true);     // Same as above 
SELECT setval('payments_id_seq', 21, false);    // Next nextval will return 21

The better way to avoid hard-coding of sequence name, next sequence value and to handle empty column table correctly, you can use the below way:

SELECT setval(pg_get_serial_sequence('table_name', 'id'), coalesce(max(id), 0)+1 , false) FROM table_name;

where table_name is the name of the table, id is the primary key of the table

Assigning $1 works but it will leave a leading space: awk '{first = $1; $1 = ""; print $0, first; }'

You can also find the number of columns in NF and use that in a loop.

https://apigee.com/console/instagram?req=%7B%22resource%22%3A%22get_tags_media_recent%22%2C%22params%22%3A%7B%22query%22%3A%7B%7D%2C%22template%22%3A%7B%22tag-name%22%3A%22snowy%22%7D%2C%22headers%22%3A%7B%7D%2C%22body%22%3A%7B%22attachmentFormat%22%3A%22mime%22%2C%22attachmentContentDisposition%22%3A%22form-data%22%7D%7D%2C%22verb%22%3A%22get%22%7D

You need to use "Authentication" as OAuth 2 and will be prompted to signin via Instagram. Post that you might have to reneter the "tag-name" in "Template" section.

All the pagination related data is available in the "pagination" parameter in the response and use it's "next_url" to query for the next set of result.

A .pl is a single script.

In .pm (Perl Module) you have functions that you can use from other Perl scripts:

A Perl module is a self-contained piece of Perl code that can be used by a Perl program or by other Perl modules. It is conceptually similar to a C link library, or a C++ class.

There are multiple ways to add the basic HTTP authentication to the RestTemplate.

1. For a single request

try {
    // request url
    String url = "https://jsonplaceholder.typicode.com/posts";

    // create auth credentials
    String authStr = "username:password";
    String base64Creds = Base64.getEncoder().encodeToString(authStr.getBytes());

    // create headers
    HttpHeaders headers = new HttpHeaders();
    headers.add("Authorization", "Basic " + base64Creds);

    // create request
    HttpEntity request = new HttpEntity(headers);

    // make a request
    ResponseEntity<String> response = new RestTemplate().exchange(url, HttpMethod.GET, request, String.class);

    // get JSON response
    String json = response.getBody();

} catch (Exception ex) {
    ex.printStackTrace();
}

If you are using Spring 5.1 or higher, it is no longer required to manually set the authorization header. Use headers.setBasicAuth() method instead:

// create headers
HttpHeaders headers = new HttpHeaders();
headers.setBasicAuth("username", "password");

2. For a group of requests

@Service
public class RestService {

    private final RestTemplate restTemplate;

    public RestService(RestTemplateBuilder restTemplateBuilder) {
        this.restTemplate = restTemplateBuilder
                .basicAuthentication("username", "password")
                .build();
    }

   // use `restTemplate` instance here
}

3. For each and every request

@Bean
RestOperations restTemplateBuilder(RestTemplateBuilder restTemplateBuilder) {
    return restTemplateBuilder.basicAuthentication("username", "password").build();
}

I hope it helps!

var str1 = 'abc';
var str2 = str1+' def'; // str2 is now 'abc def'

Addition to BeNdErR's answer:
The "other TEXT" element should have float:none, like:

    <div style="width:100%;">_x000D_
        <div style="float:left;width:30%; background:red;">...something something something  random text</div>_x000D_
        <div style="float:none; background:yellow;"> text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text  </div>_x000D_
    </div>

Python lists are mutable objects and here:

plot_data = [[]] * len(positions) 

you are repeating the same list len(positions) times.

>>> plot_data = [[]] * 3
>>> plot_data
[[], [], []]
>>> plot_data[0].append(1)
>>> plot_data
[[1], [1], [1]]
>>> 

Each list in your list is a reference to the same object. You modify one, you see the modification in all of them.

If you want different lists, you can do this way:

plot_data = [[] for _ in positions]

for example:

>>> pd = [[] for _ in range(3)]
>>> pd
[[], [], []]
>>> pd[0].append(1)
>>> pd
[[1], [], []]

you may try this one, used CONCAT

WHERE LastName LIKE Concat('%',@LastName,'%')

For me what worked was:

Uninstall and then reinstall the referenced Nuget package that has the error.

the best way if you use Spring Boot is :

1/ Create a ServletInitializer extends SpringBootServletInitializer Class . With method configure which run your Application Class

2/ Generate always a maven install WAR file

3/ With this artefact you can even :

    . start application from war file with java -jar file.war

    . put your war file in your favorite Web App server (like tomcat, ...)

In Java there is no good reason.

A couple of other answers have claimed that it's because you can accidentally make it assignment instead of equality. But in Java, you have to have a boolean in an if, so this:

if (o = null)

will not compile.

The only time this could matter in Java is if the variable is boolean:

int m1(boolean x)
{
    if (x = true)  // oops, assignment instead of equality

You can do something like this to read 10 bytes:

char buffer[10];
read(STDIN_FILENO, buffer, 10);

remember read() doesn't add '\0' to terminate to make it string (just gives raw buffer).

To read 1 byte at a time:

char ch;
while(read(STDIN_FILENO, &ch, 1) > 0)
{
 //do stuff
}

and don't forget to #include <unistd.h>, STDIN_FILENO defined as macro in this file.

There are three standard POSIX file descriptors, corresponding to the three standard streams, which presumably every process should expect to have:

Integer value   Name
       0        Standard input (stdin)
       1        Standard output (stdout)
       2        Standard error (stderr)

So instead STDIN_FILENO you can use 0.

Edit:
In Linux System you can find this using following command:

$ sudo grep 'STDIN_FILENO' /usr/include/* -R | grep 'define'
/usr/include/unistd.h:#define   STDIN_FILENO    0   /* Standard input.  */

Notice the comment /* Standard input. */

As mentioned by Klap "android.R.layout.simple_list_item_1 is a reference to an built-in XML layout document that is part of the Android OS"
All the layouts are located in: sdk\platforms\android-xx\data\res\layout
To view the XML of layout :
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select "Open declaration in layout/simple_list_item_1.xml". It'll direct you to the contents of the XML.
Android Studio: Project Window -> External Libraries -> Android X Platform -> res -> layout, and here you will see a list of available layouts.

I ran into this problem with templated classes. Here's a more general solution I had to use:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // Friend means operator<< can use private variables
    // It needs to be declared as a template, but T is taken
    template <class U>
    friend std::ostream& operator<<(std::ostream&, const myClass<U> &);
}

// Operator is a non-member and global, so it's not myClass<U>::operator<<()
// Because of how C++ implements templates the function must be
// fully declared in the header for the linker to resolve it :(
template <class U>
std::ostream& operator<<(std::ostream& os, const myClass<U> & obj)
{
  obj.toString(os);
  return os;
}

Now: * My toString() function can't be inline if it is going to be tucked away in cpp. * You're stuck with some code in the header, I couldn't get rid of it. * The operator will call the toString() method, it's not inlined.

The body of operator<< can be declared in the friend clause or outside the class. Both options are ugly. :(

Maybe I'm misunderstanding or missing something, but just forward-declaring the operator template doesn't link in gcc.

This works too:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // For some reason this requires using T, and not U as above
    friend std::ostream& operator<<(std::ostream&, const myClass<T> &)
    {
        obj.toString(os);
        return os;
    }
}

I think you can also avoid the templating issues forcing declarations in headers, if you use a parent class that is not templated to implement operator<<, and use a virtual toString() method.

I also had same problem and I fixed it by using right proxy. Please double check your proxy settings if you are using proxy network.

Hope this will help you -

The other solutions do not work for chrome driver v83.

Instead, it works as follows, suppose there is only 1 opening tab:

driver.execute_script("window.open('');")
driver.switch_to.window(driver.window_handles[1])
driver.get("https://www.example.com")

If there are already more than 1 opening tabs, you should first get the index of the last newly-created tab and switch to the tab before calling the url (Credit to tylerl) :

driver.execute_script("window.open('');")
driver.switch_to.window(len(driver.window_handles)-1)
driver.get("https://www.example.com")

I think token should be handled just like password. As such, they should be encrypted in DB.

I'n doing something like this to generate a unique new token for a model:

key = ActiveSupport::KeyGenerator
                .new(Devise.secret_key)
                .generate_key("put some random or the name of the key")

loop do
  raw = SecureRandom.urlsafe_base64(nil, false)
  enc = OpenSSL::HMAC.hexdigest('SHA256', key, raw)

  break [raw, enc] unless Model.exist?(token: enc)
end

Specifying a non-static position, e.g., position: absolute/relative on a node means that it will be used as the reference for absolutely positioned elements within it http://jsfiddle.net/E5eEk/1/

See https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Positioning#Positioning_contexts

We can change the positioning context — which element the absolutely positioned element is positioned relative to. This is done by setting positioning on one of the element's ancestors.

#outer {_x000D_
  min-width: 2000px; _x000D_
  min-height: 1000px; _x000D_

If your purpose is to matching with another string by converting in one pass, you can use str.casefold() as well.

This is useful when you have non-ascii characters and matching with ascii versions(eg: maße vs masse).Though str.lower or str.upper fails in such cases, str.casefold() will pass. This is available in Python 3 and the idea is discussed in detail with the answer https://stackoverflow.com/a/31599276/4848659.

>>>str="Hello World";
>>>print(str.lower());
hello world
>>>print(str.upper());
HELLO WOLRD
>>>print(str.casefold());
hello world

When a static constructor throws an exception, it is wrapped inside a TypeInitializationException. You need to check the exception object's InnerException property to see the actual exception.

In a staging / production environment (where you don't have Visual Studio installed), you'll need to either:

1. Trace/Log the exception and its InnerException (recursively): Add an event handler to the AppDomain.UnhandledException event, and put your logging/tracing code there. Use System.Diagnostics.Debug.WriteLine for tracing, or a logger (log4net, ETW). DbgView (a Sysinternals tool) can be used to view the Debug.WriteLine trace.
2. Use a production debugger (such as WinDbg or NTSD) to diagnose the exception.
3. Use Visual Studio's Remote Debugging to diagnose the exception (enabling you to debug the code on the target computer from your own development computer).

JavaScript inserted as DOM text will not execute. However, you can use the dynamic script pattern to accomplish your goal. The basic idea is to move the script that you want to execute into an external file and create a script tag when you get your Ajax response. You then set the src attribute of your script tag and voila, it loads and executes the external script.

This other StackOverflow post may also be helpful to you: Can scripts be inserted with innerHTML?.

Adding in example for solution given earlier. By using socket.io-client https://github.com/socketio/socket.io-client

Client Side:

//client.js
var io = require('socket.io-client');
var socket = io.connect('http://localhost:3000', {reconnect: true});

// Add a connect listener
socket.on('connect', function (socket) {
    console.log('Connected!');
});
socket.emit('CH01', 'me', 'test msg');

Server Side :

//server.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

io.on('connection', function (socket){
   console.log('connection');

  socket.on('CH01', function (from, msg) {
    console.log('MSG', from, ' saying ', msg);
  });

});

http.listen(3000, function () {
  console.log('listening on *:3000');
});

Run :

Open 2 console and run node server.js and node client.js

For me this error was due to the reason Gradle as installed as sudo and I was trying as default user to run Gradle.

Try:

sudo gradle -version

or

sudo gradle -v

Maybe something like this, where you could select more than one element if you'd like?

$("#number").each(function(){
    $(this).val(parseFloat($(this).val()).toFixed(2));
});

If you include all files of *.js in directory example ("app/lib/*.js"):

In directory app/lib

example.js:

module.exports = function (example) { }

example-2.js:

module.exports = function (example2) { }

In directory app create index.js

index.js:

module.exports = require('./app/lib');

use & in place of &

change to

<string name="magazine">Newspaper &amp; Magazines</string>

You could use overridePendingTransition in startActivity instead of onCreate. At least, that works for me!

See a full example here. It's including an (reverse) animation onBackPressed, so while returning to the previous activity! In your specific example (fade-in and -out) that might be unnecessary though.

I think you're looking for SELECT INTO:

select test_table.name into name from test_table where id = x;

That will pull the name from test_table where id is your function's argument and leave it in the name variable. Don't leave out the table name prefix on test_table.name or you'll get complaints about an ambiguous reference.

Another option is to update the Microsoft.AspnNet.Mvc NuGet package. Be careful, because NuGet update does not update the Web.Config. You should update all previous version numbers to updated number. For example if you update from asp.net MVC 4.0.0.0 to 5.0.0.0, then this should be replaced in the Web.Config:

    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>
  </configSections>

You have to set a reference to the workbook you're opening. Then you can do anything you want with that workbook by using its reference.

Dim wkb As Workbook
Set wkb = Workbooks.Open("Tire.xls") ' open workbook and set reference!

wkb.Sheets("Sheet1").Activate
wkb.Sheets("Sheet1").Cells(2, 1).Value = 123

Could even set a reference to the sheet, which will make life easier later:

Dim wkb As Workbook
Dim sht As Worksheet

Set wkb = Workbooks.Open("Tire.xls")
Set sht = wkb.Sheets("Sheet2")

sht.Activate
sht.Cells(2, 1) = 123

Others have pointed out that .Activate may be superfluous in your case. You don't strictly need to activate a sheet before editing its cells. But, if that's what you want to do, it does no harm to activate -- except for a small hit to performance which should not be noticeable as long as you do it only once or a few times. However, if you activate many times e.g. in a loop, it will slow things down significantly, so activate should be avoided.

This is how Adding new column to Table

ALTER TABLE [tableName]
ADD ColumnName Datatype

E.g

ALTER TABLE [Emp]
ADD Sr_No Int

And If you want to make it auto incremented

ALTER TABLE [Emp]
ADD Sr_No Int IDENTITY(1,1) NOT NULL

func Ternary(statement bool, a, b interface{}) interface{} {
    if statement {
        return a
    }
    return b
}

func Abs(n int) int {
    return Ternary(n >= 0, n, -n).(int)
}

This will not outperform if/else and requires cast but works. FYI:

BenchmarkAbsTernary-8 100000000 18.8 ns/op

BenchmarkAbsIfElse-8 2000000000 0.27 ns/op

i'm not sure what you're expecting this to refer to in your example.. here's an alternative method:

<html>
    <head>
        <script src="http://code.jquery.com/jquery-1.6.4.min.js" type="text/javascript"></script>
        <script type="text/javascript">
            $(function () {
                $.get("banner.html", function (data) {
                    $("#appendToThis").append(data);
                });
            });
        </script>
    </head>
    <body>
        <div id="appendToThis"></div>
    </body>
</html>

@echo off
xcopy ...

Replace ... with the appropriate xcopy arguments to copy what you want copied.

The easiest way is probably to use xvfb-run:

DISPLAY=:1 xvfb-run java -jar selenium-server-standalone-2.0b3.jar

xvfb-run does the whole X authority dance for you, give it a try!

Perhaps:

> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)

PS> I posted this answer on a related question. Here's how I got round the issue of my async ajax request losing the trusted context:

I opened the popup directly on the users click, directed the url to about:blank and got a handle on that window. You could probably direct the popup to a 'loading' url while your ajax request is made

var myWindow = window.open("about:blank",'name','height=500,width=550');

Then, when my request is successful, I open my callback url in the window

function showWindow(win, url) {
     win.open(url,'name','height=500,width=550');
}

class Foo(object):
     bar = 1
     def bah(self):
         print Foo.bar

f = Foo() 
f.bah()

-O is the option to specify the path of the file you want to download to:

wget <uri> -O /path/to/file.ext

-P is prefix where it will download the file in the directory:

wget <uri> -P /path/to/folder

If you are using ConstraintLayout, just put the element after the other elements to make it on front than the others

Eric Niebler is working on a range-proposal and some of the examples show how to remove certain elements. Removing 8. Does create a new vector.

#include <iostream>
#include <range/v3/all.hpp>

int main(int argc, char const *argv[])
{
    std::vector<int> vi{2,4,6,8,10};
    for (auto& i : vi) {
        std::cout << i << std::endl;
    }
    std::cout << "-----" << std::endl;
    std::vector<int> vim = vi | ranges::view::remove_if([](int i){return i == 8;});
    for (auto& i : vim) {
        std::cout << i << std::endl;
    }
    return 0;
}

outputs

In computer programming, a callback is executable code that is passed as an argument to other code.

—Wikipedia: Callback (computer science)

C# has delegates for that purpose. They are heavily used with events, as an event can automatically invoke a number of attached delegates (event handlers).

Add to your manifest

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"
    tools:ignore="MockLocation,ProtectedPermissions" />

Mock location function

void setMockLocation() {
    LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    locationManager.addTestProvider(LocationManager.GPS_PROVIDER, false, false,
            false, false, true, true, true, 0, 5);
    locationManager.setTestProviderEnabled(LocationManager.GPS_PROVIDER, true);

    Location mockLocation = new Location(LocationManager.GPS_PROVIDER);
    mockLocation.setLatitude(-33.852);  // Sydney
    mockLocation.setLongitude(151.211);
    mockLocation.setAltitude(10);
    mockLocation.setAccuracy(5);
    mockLocation.setTime(System.currentTimeMillis());
    mockLocation.setElapsedRealtimeNanos(System.nanoTime());
    locationManager.setTestProviderLocation(LocationManager.GPS_PROVIDER, mockLocation);
}

You'll also need to enable mock locations in your devices developer settings. If that's not available, set the "mock location application" to your application once the above has been implemented.

Because the type is unknown at run-time, I wrote code as follows to compare the unknown object, not against a type, but against an object of known type:

1. Create a sample object of the right type
2. Specify which of its elements are optional
3. Do a deep compare of your unknown object against this sample object

Here's the (interface-agnostic) code I use for the deep compare:

  }

  assertType(loaded, wanted);
  return loaded as T;
}

Below is an example of how I use it.

In this example I expect the JSON contains an array of tuples, of which the second element is an instance of an interface called User (which has two optional elements).

TypeScript's type-checking will ensure that my sample object is correct, then the assertTypeT function checks that the unknown (loaded from JSON) object matches the sample object.

export function loadUsers(): Map<number, User> {
  const found = require("./users.json");
  const sample: [number, User] = [
    49942,
    {
      "name": "ChrisW",
      "email": "[email protected]",
      "gravatarHash": "75bfdecf63c3495489123fe9c0b833e1",
      "profile": {
        "location": "Normandy",
        "aboutMe": "I wrote this!\n\nFurther details are to be supplied ..."
      },
      "favourites": []
    }
  ];
  const optional: Set<string> = new Set<string>(["profile.aboutMe", "profile.location"]);
  const loaded: [number, User][] = assertTypeT(found, [sample], optional);
  return new Map<number, User>(loaded);
}

You could invoke a check like this in the implementation of a user-defined type guard.

If you have a newer version of the Anaconda Navigator, open the Anaconda Prompt program that came in the install. Type all the usual conda update/conda install commands there.

I think the answers above explain this, but I could have used a very simple instruction like this. Perhaps it will help others.

If you run into issues with grabbing the source .dot directly you can also use Source.from_file like this:

from graphviz import Source
from sklearn import tree
tree.export_graphviz(dtreg, out_file='tree.dot', feature_names=X.columns)
Source.from_file('tree.dot')

In addition to the other answers here showing you how to git checkout <the-hash-you-want> it's worth knowing you can switch back to where you were using:

git checkout @{-1}

This is often more convenient than:

git checkout what-was-that-original-branch-called-again-question-mark

As you might anticipate, git checkout @{-2} will take you back to the branch you were at two git checkouts ago, and similarly for other numbers. If you can remember where you were for bigger numbers, you should get some kind of medal for that.

Sadly for productivity, git checkout @{1} does not take you to the branch you will be on in future, which is a shame.

In order to check if your variable is something you could go like:

s='Hello World'
if isinstance(s,str):
#do something here,

The output of isistance will give you a boolean True or False value so you can adjust accordingly. You can check the expected acronym of your value by initially using: type(s) This will return you type 'str' so you can use it in the isistance function.

Here is an excerpt from the Book Deep Learning with TensorFlow

In some cases it is desirable for the process to only allocate a subset of the available memory, or to only grow the memory usage as it is needed by the process. TensorFlow provides two configuration options on the session to control this. The first is the allow_growth option, which attempts to allocate only as much GPU memory based on runtime allocations, it starts out allocating very little memory, and as sessions get run and more GPU memory is needed, we extend the GPU memory region needed by the TensorFlow process.

1) Allow growth: (more flexible)

config = tf.ConfigProto()
config.gpu_options.allow_growth = True
session = tf.Session(config=config, ...)

The second method is per_process_gpu_memory_fraction option, which determines the fraction of the overall amount of memory that each visible GPU should be allocated. Note: No release of memory needed, it can even worsen memory fragmentation when done.

2) Allocate fixed memory:

To only allocate 40% of the total memory of each GPU by:

config = tf.ConfigProto()
config.gpu_options.per_process_gpu_memory_fraction = 0.4
session = tf.Session(config=config, ...)

Note: That's only useful though if you truly want to bind the amount of GPU memory available on the TensorFlow process.

You need to use the select new LINQ keyword to explicitly convert your tbcourseentity into the custom type course. Example of select new:

var q = from o in db.Orders
        where o.Products.ProductName.StartsWith("Asset") && 
              o.PaymentApproved == true
        select new { name   = o.Contacts.FirstName + " " +
                              o.Contacts.LastName, 
                     product = o.Products.ProductName, 
                     version = o.Products.Version + 
                              (o.Products.SubVersion * 0.1)
                   };

PHP comes with two native functions to show which config file is loaded :

• php_ini_loaded_file return the loaded ini file
• php_ini_scanned_files return a list of .ini files parsed from the additional ini dir

Depending on your setup, Apache and CLI might use different ini files. Here are the two solutions :

Apache :

Just add the following in a php file and open it in your browser

print php_ini_loaded_file();
print_r(php_ini_scanned_files());

CLI :

Copy-paste in your terminal :

php -r 'print php_ini_loaded_file(); print_r(php_ini_scanned_files());'

If you have multiple Java versions installed on your Mac, here's a quick way to switch the default version using Terminal. In this example, I am going to switch Java 10 to Java 8.

$ java -version
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    10.0.1, x86_64: "Java SE 10.0.1"    /Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home
    1.8.0_171, x86_64:  "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home

/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home

Then, in your .bash_profile add the following.

# Java 8
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home

Now if you try java -version again, you should see the version you want.

$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

For the record, general_log and slow_log were introduced in 5.1.6:

http://dev.mysql.com/doc/refman/5.1/en/log-destinations.html

5.2.1. Selecting General Query and Slow Query Log Output Destinations

As of MySQL 5.1.6, MySQL Server provides flexible control over the destination of output to the general query log and the slow query log, if those logs are enabled. Possible destinations for log entries are log files or the general_log and slow_log tables in the mysql database

You certainly are able to have multiple CTEs in a single query expression. You just need to separate them with a comma. Here is an example. In the example below, there are two CTEs. One is named CategoryAndNumberOfProducts and the second is named ProductsOverTenDollars.

WITH CategoryAndNumberOfProducts (CategoryID, CategoryName, NumberOfProducts) AS
(
   SELECT
      CategoryID,
      CategoryName,
      (SELECT COUNT(1) FROM Products p
       WHERE p.CategoryID = c.CategoryID) as NumberOfProducts
   FROM Categories c
),

ProductsOverTenDollars (ProductID, CategoryID, ProductName, UnitPrice) AS
(
   SELECT
      ProductID,
      CategoryID,
      ProductName,
      UnitPrice
   FROM Products p
   WHERE UnitPrice > 10.0
)

SELECT c.CategoryName, c.NumberOfProducts,
      p.ProductName, p.UnitPrice
FROM ProductsOverTenDollars p
   INNER JOIN CategoryAndNumberOfProducts c ON
      p.CategoryID = c.CategoryID
ORDER BY ProductName

Try this it will work. Do not enter password it will ask one you execute the following cmd

C:\xampp\mysql\bin\mysql -u xxxxx -p -h localhost your_database_name < c:\yourfile.sql

I have found a slightly different way implement pointers that is perhaps more general and easier to understand from a C perspective (and thus fits more into the format of the users example).

In JavaScript, like in C, array variables are actually just pointers to the array, so you can use an array as exactly the same as declaring a pointer. This way, all pointers in your code can be used the same way, despite what you named the variable in the original object.

It also allows one to use two different notations referring to the address of the pointer and what is at the address of the pointer.

Here is an example (I use the underscore to denote a pointer):

var _x = [ 10 ];

function foo(_a){
    _a[0] += 10;
}

foo(_x);

console.log(_x[0]);

Yields

output: 20

If something does not work, when coming thru the front-door, then take the back-door:

drop table if exists apples;
create table if not exists apples(variety char(10) primary key, price int);

insert into apples values('fuji', 5), ('gala', 6);

drop table if exists apples_new;
create table if not exists apples_new like apples;
insert into apples_new select * from apples;

update apples_new
    set price = (select price from apples where variety = 'gala')
    where variety = 'fuji';
rename table apples to apples_orig;
rename table apples_new to apples;
drop table apples_orig;

It's fast. The bigger the data, the better.

Per Apple Documentation

For 64-bit and iPhone OS applications, there is a linker bug that prevents -ObjC from loading objects files from static libraries that contain only categories and no classes. The workaround is to use the -all_load or -force_load flags.

In short add -all_load to "other linker" flags in your "Build Settings" and you should be good.

I would like to make this answer for meaningful, so the same kind of erroneous user can enjoy without feel any hassle.

Actually, i was getting the same error but for the different reason, in my case I didn't used any kind of quoted, still getting the same error like expected <block end>, but found BlockMappingStart.

I have solved it by fixing, the Alignment issue inside the same .yml file.

If we don't manage the proper 'tab-space(Keyboard key)' for maintaining successor or ancestor then we have to phase such kind of things.

Now i am doing well.

In PHP this did it for me (assuming the filename is UTF8 encoded):

header('Content-Disposition: attachment;'
    . 'filename="' . addslashes(utf8_decode($filename)) . '";'
    . 'filename*=utf-8\'\'' . rawurlencode($filename));

Tested against IE8-11, Firefox and Chrome.
If the browser can interpret filename*=utf-8 it will use the UTF8 version of the filename, else it will use the decoded filename. If your filename contains characters that can't be represented in ISO-8859-1 you might want to consider using iconv instead.

There are a lot of things in C that aren't technically needed because they can be more or less easily implemented in terms of other things. Here is an incomplete list:

1. while
2. for
3. functions
4. structs

Imagine what your code would look like without these and you may find your answer. The ternary operator is a form of "syntactic sugar" that if used with care and skill makes writing and understanding code easier.

setting Cellpadding and cellspacing to 0 will remove the unnecessary space between rows and columns...

I see that they did not understand your question.

Answer is: add "traditional" parameter to your ajax call like this:

$.ajax({
  traditional: true,
  type: "POST",
  url: url,
  data: custom,
  success: ok,
  dataType: "json"
});

And it will work with parameters PASSED AS A STRING.

I also had this problem when doing migration => after performing php artisan migrate:refresh --seed command

"Base table or view not found: 1146 Table posts do not exist" and I solved it, I was using "soft deletes" in a separate migration file, and my original migration for "posts" table which was responsible for creating the "posts" table was performing after the "soft deletes" migration in the database\migration folder, I simply needed to rename the "posts" migration file name and put it before "softdeletes" migration to perform sooner. the do the migration again => php artisan migrate:refresh --seed it's done.

(x > 0 for x in list) in that function call creates a generator expression eg.

>>> nums = [1, 2, -1, 9, -5]
>>> genexp = (x > 0 for x in nums)
>>> for x in genexp:
        print x


True
True
False
True
False

Which any uses, and shortcircuits on encountering the first object that evaluates True

I know this is old but you should also try Zombie.js. A headless browser which is insanely fast and ideal for testing !

I'm not sure exactly what you want, but I think it's along the lines of:

SELECT `Item`, `qty`-`BAL_QTY` as `qty` FROM ((SELECT Item, SUM(`QTY`) as qty FROM `master_table` GROUP BY `ITEM`) as A NATURAL JOIN `stock_table`) as B

To validate base64 image we can use this regex

/^data:image/(?:gif|png|jpeg|bmp|webp)(?:;charset=utf-8)?;base64,(?:[A-Za-z0-9]|[+/])+={0,2}

  private validBase64Image(base64Image: string): boolean {
    const regex = /^data:image\/(?:gif|png|jpeg|bmp|webp)(?:;charset=utf-8)?;base64,(?:[A-Za-z0-9]|[+/])+={0,2}/;
    return base64Image && regex.test(base64Image);
  }

Of course it does. After replacing the variable, it reads [ !-z ], which is not a valid [ command. Use double quotes, or [[.

if [ ! -z "$errorstatus" ]

if [[ ! -z $errorstatus ]]

You can use normal CSS selectors to select an element by name using jquery. Like this:

Button Code
<button type="button" name="mybutton">Click Me!</button>

Selector & Event Bind Code
$("button[name='mybutton']").click(function() {});

preg_replace('/^[^:\/?]+:\/\//','',$url); 

some results:

input: http://php.net/preg_replace output: php.net/preg_replace  input: https://www.php.net/preg_replace output: www.php.net/preg_replace  input: ftp://www.php.net/preg_replace output: www.php.net/preg_replace  input: https://php.net/preg_replace?url=http://whatever.com output: php.net/preg_replace?url=http://whatever.com  input: php.net/preg_replace?url=http://whatever.com output: php.net/preg_replace?url=http://whatever.com  input: php.net?site=http://whatever.com output: php.net?site=http://whatever.com 

Use PowerShell to create your event log and source:

New-EventLog -LogName MyApplicationLog `
    -Source MySource `
    -MessageResourceFile C:\windows\Microsoft.NET\Framework\v4.0.30319\EventLogMessages.dll

You'll need the messages dll to avoid the problem you are seeing.

There is not much which I would like to add to Rody Oldenhuis answer. I usually follow the strategy that all functions which I write should run in Matlab.

Some specific functions I test on both systems, for the following use cases:

a) octave does not need a license server - e.g. if your institution does not support local licenses. I used it once in a situation where the system I used a script on had no connection to the internet and was going to run for a very long time (in a corner in the lab) and used by many different users. Remark: that is not about the license cost, but about the technical issues related.

b) Octave supports other platforms, for example, the Rasberry Pi (http://wiki.octave.org/Rasperry_Pi) - which may come in handy.

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

Try using p:ajax with event attribute,

you can use style

   <td  colspan="2">
     <div style="float:left; width:80px"><asp:Label ID="Label6" runat="server" Text="Label"></asp:Label></div>

    <div style="float: right; width:100px">    
            <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
    </div>

     <div style="clear:both"></div>

    </td>

If the method of this code is not static, you can get a work-around in 5.2 by using get_class($this).

class A {
    public function create1() {
        $class = get_class($this);
        return new $class();
    }
    public function create2() {
        return new static();
    }
}

class B extends A {

}

$b = new B();
var_dump(get_class($b->create1()), get_class($b->create2()));

The results:

string(1) "B"
string(1) "B"

# file? will only return true for files
File.file?(filename)

and

# Will also return true for directories - watch out!
File.exist?(filename)

Sorry for comment in an old post but if you want to use an else if statement this will help you

{% if title == source %}
    Do This
{% elif title == value %}
    Do This
{% else %}
    Do This
{% endif %}

For more info see Django Documentation

You can write directly to an event log. Check the following links:
http://support.microsoft.com/kb/307024
http://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog.aspx

And here's the sample from MSDN:

using System;
using System.Diagnostics;
using System.Threading;

class MySample{

    public static void Main(){

        // Create the source, if it does not already exist.
        if(!EventLog.SourceExists("MySource"))
        {
             //An event log source should not be created and immediately used.
             //There is a latency time to enable the source, it should be created
             //prior to executing the application that uses the source.
             //Execute this sample a second time to use the new source.
            EventLog.CreateEventSource("MySource", "MyNewLog");
            Console.WriteLine("CreatedEventSource");
            Console.WriteLine("Exiting, execute the application a second time to use the source.");
            // The source is created.  Exit the application to allow it to be registered.
            return;
        }

        // Create an EventLog instance and assign its source.
        EventLog myLog = new EventLog();
        myLog.Source = "MySource";

        // Write an informational entry to the event log.    
        myLog.WriteEntry("Writing to event log.");

    }
}

There is a few benefits of using modules. You can use it only with Apple's framework unless module map is created. @import is a bit similar to pre-compiling headers files when added to .pch file which is a way to tune app the compilation process. Additionally you do not have to add libraries in the old way, using @import is much faster and efficient in fact. If you still look for a nice reference I will highly recommend you reading this article.

to get all tables in a database:

select * from INFORMATION_SCHEMA.TABLES

to get all columns in a database:

select * from INFORMATION_SCHEMA.columns

to get all views in a db:

select * from INFORMATION_SCHEMA.TABLES where table_type = 'view'

Originally, the solution was to provide the following config as object destructuring used to be an experimental feature and not supported by default:

{
  "parserOptions": {
    "ecmaFeatures": {
      "experimentalObjectRestSpread": true
    }
  }
}

Since version 5, this option has been deprecated.

Now it is enough just to declare a version of ES, which is new enough:

{
  "parserOptions": {
    "ecmaVersion": 2018
  }
}

Translate all characters into their hex-entity equivalents. In this case, Null would be converted into &#4E;K&#6C;&#6C;

I use one Factory module that contains one (or more) constructor per class which calls the Init member of each class.

For example a Point class:

Class Point
Private X, Y
Sub Init(X, Y)
  Me.X = X
  Me.Y = Y
End Sub

A Line class

Class Line
Private P1, P2
Sub Init(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  If P1 Is Nothing Then
    Set Me.P1 = NewPoint(X1, Y1)
    Set Me.P2 = NewPoint(X2, Y2)
  Else
    Set Me.P1 = P1
    Set Me.P2 = P2
  End If
End Sub

And a Factory module:

Module Factory
Function NewPoint(X, Y)
  Set NewPoint = New Point
  NewPoint.Init X, Y
End Function

Function NewLine(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  Set NewLine = New Line
  NewLine.Init P1, P2, X1, Y1, X2, Y2
End Function

Function NewLinePt(P1, P2)
  Set NewLinePt = New Line
  NewLinePt.Init P1:=P1, P2:=P2
End Function

Function NewLineXY(X1, Y1, X2, Y2)
  Set NewLineXY = New Line
  NewLineXY.Init X1:=X1, Y1:=Y1, X2:=X2, Y2:=Y2
End Function

One nice aspect of this approach is that makes it easy to use the factory functions inside expressions. For example it is possible to do something like:

D = Distance(NewPoint(10, 10), NewPoint(20, 20)

or:

D = NewPoint(10, 10).Distance(NewPoint(20, 20))

It's clean: the factory does very little and it does it consistently across all objects, just the creation and one Init call on each creator.

And it's fairly object oriented: the Init functions are defined inside the objects.

EDIT

I forgot to add that this allows me to create static methods. For example I can do something like (after making the parameters optional):

NewLine.DeleteAllLinesShorterThan 10

Unfortunately a new instance of the object is created every time, so any static variable will be lost after the execution. The collection of lines and any other static variable used in this pseudo-static method must be defined in a module.

If you want to use pure Ruby (no Rails), don't want to create extension methods (maybe you need this only in one or two places and don't want to pollute namespace with tons of methods) and don't want to edit hash in place (i.e., you're fan of functional programming like me), you can 'select':

>> x = {:a => 1, :b => 2, :c => 3}
=> {:a=>1, :b=>2, :c=>3}
>> x.select{|x| x != :a}
=> {:b=>2, :c=>3}
>> x.select{|x| ![:a, :b].include?(x)}
=> {:c=>3}
>> x
=> {:a=>1, :b=>2, :c=>3}

Just a suggestion, but you might try the Pear Mail_Mime class instead.

http://pear.php.net/package/Mail_Mime/docs

Otherwise you can use a bit of code. Gabi Purcaru method of using rename() won't work the way it's written. See this post http://us3.php.net/manual/en/function.rename.php#97347 . You'll need something like this:

$dir = dirname($_FILES["file"]["tmp_name"]);
$destination = $dir . DIRECTORY_SEPARATOR . $_FILES["file"]["name"];
rename($_FILES["file"]["tmp_name"], $destination);
$geekMail->attach($destination);

This also works in Java 8 :

Path file = Paths.get("Some path");
file = Paths.get(file + "Some other path");

Any MD5 will produce a good checksum to verify the file. Any of the files listed at the bottom of this page will work fine. http://en.wikipedia.org/wiki/Md5sum

You have to first Install JDK in your system.

Set Java Home

JAVA_HOME = C:\Program Files\Java\jdk1.7.0 [Location of your JDK Installation Directory]

Once you have the JDK installation path:

• Right-click the My Computer icon on
• Select Properties.
• Click the Advanced system setting tab on left side of your screen
• Aadvance Popup is open.
• Click on Environment Variables button.

• Under System Variables, click New.
• Enter the variable name as JAVA_HOME.
• Enter the variable value as the installation path for the Java Development Kit.
• Click OK.
• Click Apply Changes.

Set JAVA Path under system variable

PATH= C:\Program Files\Java\jdk1.7.0; [Append Value with semi-colon]

If performance/memory usage is an issue then, this one only creates one (1) StringBuilder and one (1) new String of the same size as the Original string.

public static string ToUpperFirst(this string str) {
  if( !string.IsNullOrEmpty( str ) ) {
    StringBuilder sb = new StringBuilder(str);
    sb[0] = char.ToUpper(sb[0]);

    return sb.ToString();

  } else return str;
}

I think you want to use

mysql_fetch_assoc($query)

rather than

mysql_fetch_row($query)

The latter returns an normal array index by integers, whereas the former returns an associative array, index by the field names.

The simple solution

SELECT CAST(CollectionDate as DATETIME) + CAST(CollectionTime as DATETIME)
FROM field

I solved this problem in the following way:

Check if the columns contain Nan using .isnull() and check for empty strings using .eq(''), then join the two together using the bitwise OR operator |.

Sum along axis 0 to find columns with missing data, then sum along axis 1 to the index locations for rows with missing data.

missing_cols, missing_rows = (
    (df2.isnull().sum(x) | df2.eq('').sum(x))
    .loc[lambda x: x.gt(0)].index
    for x in (0, 1)
)

>>> df2.loc[missing_rows, missing_cols]
         A2       A3
2            1.10035
5 -0.508501         
6       NaN      NaN
7       NaN      NaN

If you want to convert an existing string to raw string, then we can reassign that like below

s1 = "welcome\tto\tPython"
raw_s1 = "%r"%s1
print(raw_s1)

Will print

welcome\tto\tPython

There is one thing that IntelliJ does much much better than Eclipse and that is empty your pockets!

I do however prefer using it and one big advantage it has over Eclipce is the way it synchronises with the file system, for big projects and slow computers (yes in work environments the PC's are a lot slower than our ones at home) Eclipse seems to struggle where IntelliJ seems to be quicker albeit with a slower initial indexing time.

IntelliJ Community edition obviously makes using it free but you soon want those extra refactoring and nice little goodies not included in the CC edition.

In my opinion, its generally a better user experience but whether its worth the cost is a question for each developer to answer themselves.

But lets be grateful we have up to three great IDEs for Java right now with NetBeans getting better all the time.

Write one table per join, like this:

select tab1.a,tab2.b,tab3.c,tab4.d 
from 
  table1 tab1
  inner join table2 tab2 on tab2.fg = tab1.fg
  left join table3 tab3 on tab3.xxx = tab1.xxx and tab3.desc = "XYZ"
  left join table4 tab4 on tab4.xya = tab3.xya and tab4.ss = tab3.ss
  left join table5 tab5 on tab5.dd = tab3.dd and tab5.kk = tab4.kk

Note that while my query contains actual left join, your query apparently doesn't. Since the conditions are in the where, your query should behave like inner joins. (Although I admit I don't know Informix, so maybe I'm wrong there).

The specfific Informix extension used in the question works a bit differently with regards to left joins. Apart from the exact syntax of the join itself, this is mainly in the fact that in Informix, you can specify a list of outer joined tables. These will be left outer joined, and the join conditions can be put in the where clause. Note that this is a specific extension to SQL. Informix also supports 'normal' left joins, but you can't combine the two in one query, it seems.

In Oracle this extension doesn't exist, and you can't put outer join conditions in the where clause, since the conditions will be executed regardless.

So look what happens when you move conditions to the where clause:

select tab1.a,tab2.b,tab3.c,tab4.d 
from 
  table1 tab1
  inner join table2 tab2 on tab2.fg = tab1.fg
  left join table3 tab3 on tab3.xxx = tab1.xxx
  left join table4 tab4 on tab4.xya = tab3.xya
  left join table5 tab5 on tab5.dd = tab3.dd and tab5.kk = tab4.kk
where
  tab3.desc = "XYZ" and
  tab4.ss = tab3.ss

Now, only rows will be returned for which those two conditions are true. They cannot be true when no row is found, so if there is no matching row in table3 and/or table4, or if ss is null in either of the two, one of these conditions is going to return false, and no row is returned. This effectively changed your outer join to an inner join, and as such changes the behavior significantly.

PS: left join and left outer join are the same. It means that you optionally join the second table to the first (the left one). Rows are returned if there is only data in the 'left' part of the join. In Oracle you can also right [outer] join to make not the left, but the right table the leading table. And there is and even full [outer] join to return a row if there is data in either table.

OUTDATED: Many modern browsers now have first-class support for crypto operations. See Vitaly Zdanevich's answer below.

The Stanford JS Crypto Library contains an implementation of SHA-256. While crypto in JS isn't really as well-vetted an endeavor as other implementation platforms, this one is at least partially developed by, and to a certain extent sponsored by, Dan Boneh, who is a well-established and trusted name in cryptography, and means that the project has some oversight by someone who actually knows what he's doing. The project is also supported by the NSF.

It's worth pointing out, however...
... that if you hash the password client-side before submitting it, then the hash is the password, and the original password becomes irrelevant. An attacker needs only to intercept the hash in order to impersonate the user, and if that hash is stored unmodified on the server, then the server is storing the true password (the hash) in plain-text.

So your security is now worse because you decided add your own improvements to what was previously a trusted scheme.

shopt -s nocaseglob

The only half-way proper way to do this is

<p>
  <span style="float: right">Text on the right</span>
  <span style="float: left">Text on the left</span>
</p> 

however, this will get you into trouble if the text overflows. If you can, use divs (block level elements) and give them a fixed width.

A table (or a number of divs with the according display: table / table-row / table-cell properties) would in fact be the safest solution for this - it will be impossible to break, even if you have lots of difficult content.

I had similar problem, but the wrong setting was in the extern .lib file from which I did not have sources. If you do not have the source files, the simplest workaround is to just change the content of the .lib file.

Open the .lib file in an editor (I used PSPad, bud Windows notepad is also possible) and replace all occurences of _ITERATOR_DEBUG_LEVEL=2 to _ITERATOR_DEBUG_LEVEL=0

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")

1. In Swift

   let alertController = UIAlertController(title:"Title", message: "Message", preferredStyle:.alert)
   
   let Action = UIAlertAction.init(title: "Ok", style: .default) { (UIAlertAction) in
       // Write Your code Here
   }
   
   alertController.addAction(Action)
   self.present(alertController, animated: true, completion: nil)
   

2. In Objective C

   UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];
   
   UIAlertAction *OK = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action)
   {
   }];
   
   [alertController addAction:OK];
   
   [self presentViewController:alertController animated:YES completion:nil];
   

Also, if you want cellspacing="0", don't forget to add border-collapse: collapse in your table's stylesheet.

gene_name = no_headers.iloc[1:,[1]]

This creates a DataFrame because you passed a list of columns (single, but still a list). When you later do this:

gene_name[x]

you now have a Series object with a single value. You can't hash the Series.

The solution is to create Series from the start.

gene_type = no_headers.iloc[1:,0]
gene_name = no_headers.iloc[1:,1]
disease_name = no_headers.iloc[1:,2]

Also, where you have orph_dict[gene_name[x]] =+ 1, I'm guessing that's a typo and you really mean orph_dict[gene_name[x]] += 1 to increment the counter.

you don’t need a select … from dual, just write:

SELECT t.*, dbms_random.value(1,9) RandomNumber
  FROM myTable t

Use convert from http://www.imagemagick.org. (Readily supplied as a package in most Linux distributions.)

I can't comment yet (working on reputation) but created an account just to answer @Tech Jerk @spankmaster79 (nice name lol) and @NMC issues they reported in reply to the "I found a solution that is similar to the one with psexec but works without additional tools and survives a reboot." post @Larry had made.

The solution to this is to just browse to that folder from within the logged in account, ie:

    \\servername\share  

and let it prompt to login, and enter the same credentials you used for the UNC in psexec. After that it starts working. In my case, I think this is because the server with the service isn't a member of the same domain as the server I'm mapping to. I'm thinking if the UNC and the scheduled task both refer to the IP instead of hostname

    \\123.456.789.012\share 

it may avoid the problem altogether.

If I ever get enough rep points on here i'll add this as a reply instead.

On a different note, it is also always a good practice to add a token to your form and verify it to check if the data was not sent from outside. Here are the steps:

1. Generate a unique token (you can use hash) Ex:

   $token = hash (string $algo , string $data [, bool $raw_output = FALSE ] );
   

2. Assign this token to a session variable. Ex:

   $_SESSION['form_token'] = $token;
   

3. Add a hidden input to submit the token. Ex:

   input type="hidden" name="token" value="{$token}"
   

4. then as part of your validation, check if the submitted token matches the session var.

   Ex: if ( $_POST['token'] === $_SESSION['form_token'] ) ....
   

It doesn't matter at all, but class makes it look like T can only be a class, while it can of course be any type. So typename is more accurate. On the other hand, most people use class, so that is probably easier to read generally.

The best way around this is (and many other situations) in my experience, is to use cntlm which is a local no-authentication proxy which points to a remote authentication proxy. You can then just set WinHTTP to point to your local CNTLM (usually localhost:3128), and you can set CNTLM itself to point to the remote authentication proxy. CNTLM has a "magic NTLM dialect detection" option which generates password hashes to be put into the CNTLM configuration files.

The following retrieves the jpg, tiff and bmp files and gives you an IEnumerable<FileInfo> over which you can iterate:

var files = dinfo.GetFiles("*.jpg")
    .Concat(dinfo.GetFiles("*.tiff"))
    .Concat(dinfo.GetFiles("*.bmp"));

If you really need an array, simply stick .ToArray() at the end of this.

You need to cast it to a string (not an array of string) since it's a single value.

var cellValue = (string)(excelWorksheet.Cells[10, 2] as Excel.Range).Value;

Simple :

    <div style='overflow-x:scroll;overflow-y:scroll;width:100%;height:100%'>

If you're testing this in IE, dominant-baseline and alignment-baseline are not supported.

The most effective way to center text in IE is to use something like this with "dy":

<text font-size="ANY SIZE" text-anchor="middle" "dy"="-.4em"> Ya Text </text>

The negative value will shift it up and a positive value of dy will shift it down. I've found using -.4em seems a bit more centered vertically to me than -.5em, but you'll be the judge of that.

To access field or method of an object use dot .:

user = User()
print user.fullName

If a name of the field will be defined at run time, use buildin getattr function:

field_name = "fullName"
print getattr(user, field_name) # prints content of user.fullName

Just use the std:: qualifier in front of string in your header files.

In fact, you should use it for istream and ostream also - and then you will need #include <iostream> at the top of your header file to make it more self contained.

We will look at how the contents of this array are constructed and can be manipulated to affect where the Perl interpreter will find the module files.

1. Default @INC

   Perl interpreter is compiled with a specific @INC default value. To find out this value, run env -i perl -V command (env -i ignores the PERL5LIB environmental variable - see #2) and in the output you will see something like this:

   $ env -i perl -V
   ...
   @INC:
    /usr/lib/perl5/site_perl/5.18.0/x86_64-linux-thread-multi-ld
    /usr/lib/perl5/site_perl/5.18.0
    /usr/lib/perl5/5.18.0/x86_64-linux-thread-multi-ld
    /usr/lib/perl5/5.18.0
    .
   

Note . at the end; this is the current directory (which is not necessarily the same as the script's directory). It is missing in Perl 5.26+, and when Perl runs with -T (taint checks enabled).

To change the default path when configuring Perl binary compilation, set the configuration option otherlibdirs:

Configure -Dotherlibdirs=/usr/lib/perl5/site_perl/5.16.3

2. Environmental variable PERL5LIB (or PERLLIB)

   Perl pre-pends @INC with a list of directories (colon-separated) contained in PERL5LIB (if it is not defined, PERLLIB is used) environment variable of your shell. To see the contents of @INC after PERL5LIB and PERLLIB environment variables have taken effect, run perl -V.

   $ perl -V
   ...
   %ENV:
     PERL5LIB="/home/myuser/test"
   @INC:
    /home/myuser/test
    /usr/lib/perl5/site_perl/5.18.0/x86_64-linux-thread-multi-ld
    /usr/lib/perl5/site_perl/5.18.0
    /usr/lib/perl5/5.18.0/x86_64-linux-thread-multi-ld
    /usr/lib/perl5/5.18.0
    .
   

3. -I command-line option

   Perl pre-pends @INC with a list of directories (colon-separated) passed as value of the -I command-line option. This can be done in three ways, as usual with Perl options:

   • Pass it on command line:

     perl -I /my/moduledir your_script.pl
     

   • Pass it via the first line (shebang) of your Perl script:

     #!/usr/local/bin/perl -w -I /my/moduledir
     

   • Pass it as part of PERL5OPT (or PERLOPT) environment variable (see chapter 19.02 in Programming Perl)

4. Pass it via the lib pragma

   Perl pre-pends @INC with a list of directories passed in to it via use lib.

   In a program:

   use lib ("/dir1", "/dir2");
   

   On the command line:

   perl -Mlib=/dir1,/dir2
   

   You can also remove the directories from @INC via no lib.

5. You can directly manipulate @INC as a regular Perl array.

   Note: Since @INC is used during the compilation phase, this must be done inside of a BEGIN {} block, which precedes the use MyModule statement.

   • Add directories to the beginning via unshift @INC, $dir.

   • Add directories to the end via push @INC, $dir.

   • Do anything else you can do with a Perl array.

Note: The directories are unshifted onto @INC in the order listed in this answer, e.g. default @INC is last in the list, preceded by PERL5LIB, preceded by -I, preceded by use lib and direct @INC manipulation, the latter two mixed in whichever order they are in Perl code.

• How does a Perl program know where to find the file containing Perl module it uses?

There does not seem to be a comprehensive @INC FAQ-type post on Stack Overflow, so this question is intended as one.

When to use each approach?

• If the modules in a directory need to be used by many/all scripts on your site, especially run by multiple users, that directory should be included in the default @INC compiled into the Perl binary.

• If the modules in the directory will be used exclusively by a specific user for all the scripts that user runs (or if recompiling Perl is not an option to change default @INC in previous use case), set the users' PERL5LIB, usually during user login.

  Note: Please be aware of the usual Unix environment variable pitfalls - e.g. in certain cases running the scripts as a particular user does not guarantee running them with that user's environment set up, e.g. via su.

• If the modules in the directory need to be used only in specific circumstances (e.g. when the script(s) is executed in development/debug mode, you can either set PERL5LIB manually, or pass the -I option to perl.

• If the modules need to be used only for specific scripts, by all users using them, use use lib/no lib pragmas in the program itself. It also should be used when the directory to be searched needs to be dynamically determined during runtime - e.g. from the script's command line parameters or script's path (see the FindBin module for very nice use case).

• If the directories in @INC need to be manipulated according to some complicated logic, either impossible to too unwieldy to implement by combination of use lib/no lib pragmas, then use direct @INC manipulation inside BEGIN {} block or inside a special purpose library designated for @INC manipulation, which must be used by your script(s) before any other modules are used.

  An example of this is automatically switching between libraries in prod/uat/dev directories, with waterfall library pickup in prod if it's missing from dev and/or UAT (the last condition makes the standard "use lib + FindBin" solution fairly complicated. A detailed illustration of this scenario is in How do I use beta Perl modules from beta Perl scripts?.

• An additional use case for directly manipulating @INC is to be able to add subroutine references or object references (yes, Virginia, @INC can contain custom Perl code and not just directory names, as explained in When is a subroutine reference in @INC called?).

GO ends a batch, you would only very rarely need to use it in code. Be aware that if you use it in a stored proc, no code after the GO will be executed when you execute the proc.

BEGIN and END are needed for any procedural type statements with multipe lines of code to process. You will need them for WHILE loops and cursors (which you will avoid if at all possible of course) and IF statements (well techincally you don't need them for an IF statment that only has one line of code, but it is easier to maintain the code if you always put them in after an IF). CASE statements also use an END but do not have a BEGIN.

All answers provided thus far result in potentially dangerous behavior as it is quite possible you select a dummy value that is actually part of the dataset. This is increasingly likely as you create groups with many attributes. Simply put, the approach doesn't always generalize well.

A less hacky solve is to use pd.drop_duplicates() to create a unique index of value combinations each with their own ID, and then group on that id. It is more verbose but does get the job done:

def safe_groupby(df, group_cols, agg_dict):
    # set name of group col to unique value
    group_id = 'group_id'
    while group_id in df.columns:
        group_id += 'x'
    # get final order of columns
    agg_col_order = (group_cols + list(agg_dict.keys()))
    # create unique index of grouped values
    group_idx = df[group_cols].drop_duplicates()
    group_idx[group_id] = np.arange(group_idx.shape[0])
    # merge unique index on dataframe
    df = df.merge(group_idx, on=group_cols)
    # group dataframe on group id and aggregate values
    df_agg = df.groupby(group_id, as_index=True)\
               .agg(agg_dict)
    # merge grouped value index to results of aggregation
    df_agg = group_idx.set_index(group_id).join(df_agg)
    # rename index
    df_agg.index.name = None
    # return reordered columns
    return df_agg[agg_col_order]

Note that you can now simply do the following:

data_block = [np.tile([None, 'A'], 3),
              np.repeat(['B', 'C'], 3),
              [1] * (2 * 3)]

col_names = ['col_a', 'col_b', 'value']

test_df = pd.DataFrame(data_block, index=col_names).T

grouped_df = safe_groupby(test_df, ['col_a', 'col_b'],
                          OrderedDict([('value', 'sum')]))

This will return the successful result without having to worry about overwriting real data that is mistaken as a dummy value.

break; is what you need to break out of any looping statement like for, while or do-while.

In your case, its going to be like this:-

for(int x = 10; x < 20; x++) {
         // The below condition can be present before or after your sysouts, depending on your needs.
         if(x == 15){
             break; // A unlabeled break is enough. You don't need a labeled break here.
         }
         System.out.print("value of x : " + x );
         System.out.print("\n");
}

This works quite nicely for IOS, but should also work for cocoa.

I've used a top rated answer from this page many times, but while learning React, i've found a better way to do that, without binding and without inline function inside props.

Just look here:

class Parent extends React.Component {

  constructor() {
    super();
    this.state={
      someVar: value
    }
  }

  handleChange=(someValue)=>{
    this.setState({someVar: someValue})
  }

  render() {
    return <Child handler={this.handleChange} />
  }

}

export const Child = ({handler}) => {
  return <Button onClick={handler} />
}

The key is in an arrow function:

handleChange=(someValue)=>{
  this.setState({someVar: someValue})
}

mongoose.model.find returns a Query, which has a remove function.

Update for Mongoose v5.5.3 - remove() is now deprecated. Use deleteOne(), deleteMany() or findOneAndDelete() instead.

In A1 of your new sheet, put this:

=OFFSET(Sheet1!$A$1,(ROW()-1)*7,0)

... and copy down. If you start somewhere other than row 1, change ROW() to ROW(A1) or some other cell on row 1, then copy down again.

If you want to copy the nth line but multiple columns, use the formula:

=OFFSET(Sheet1!A$1,(ROW()-1)*7,0)

This can be copied right too.

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

Yes, the post data is safe. But the origin of that data is not. This way somebody can trick user with JS into logging in to your site, while browsing attacker's web page.

In order to prevent that, django will send a random key both in cookie, and form data. Then, when users POSTs, it will check if two keys are identical. In case where user is tricked, 3rd party website cannot get your site's cookies, thus causing auth error.

    /// Serializes an object.
    /// </summary>

    {
        if (serializableObject == null) { return; }

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
            using (MemoryStream stream = new MemoryStream())
            {
                serializer.Serialize(stream, serializableObject);
                stream.Position = 0;
                xmlDocument.Load(stream);
                xmlDocument.Save(fileName);
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }
    }


    /// <summary>
    /// Deserializes an xml file into an object list

    public T DeSerializeObject<T>(string fileName)
    {
        if (string.IsNullOrEmpty(fileName)) { return default(T); }

        T objectOut = default(T);

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            string xmlString = xmlDocument.OuterXml;

            using (StringReader read = new StringReader(xmlString))
            {
                Type outType = typeof(T);

                XmlSerializer serializer = new XmlSerializer(outType);
                using (XmlReader reader = new XmlTextReader(read))
                {
                    objectOut = (T)serializer.Deserialize(reader);
                }

        }
        catch (Exception ex)

map transform one event to another. flatMap transform one event to zero or more event. (this is taken from IntroToRx)

As you want to transform your json to an object, using map should be enough.

Dealing with the FileNotFoundException is another problem (using map or flatmap wouldn't solve this issue).

To solve your Exception problem, just throw it with a Non checked exception : RX will call the onError handler for you.

Observable.from(jsonFile).map(new Func1<File, String>() {
    @Override public String call(File file) {
        try {
            return new Gson().toJson(new FileReader(file), Object.class);
        } catch (FileNotFoundException e) {
            // this exception is a part of rx-java
            throw OnErrorThrowable.addValueAsLastCause(e, file);
        }
    }
});

the exact same version with flatmap :

Observable.from(jsonFile).flatMap(new Func1<File, Observable<String>>() {
    @Override public Observable<String> call(File file) {
        try {
            return Observable.just(new Gson().toJson(new FileReader(file), Object.class));
        } catch (FileNotFoundException e) {
            // this static method is a part of rx-java. It will return an exception which is associated to the value.
            throw OnErrorThrowable.addValueAsLastCause(e, file);
            // alternatively, you can return Obersable.empty(); instead of throwing exception
        }
    }
});

You can return too, in the flatMap version a new Observable that is just an error.

Observable.from(jsonFile).flatMap(new Func1<File, Observable<String>>() {
    @Override public Observable<String> call(File file) {
        try {
            return Observable.just(new Gson().toJson(new FileReader(file), Object.class));
        } catch (FileNotFoundException e) {
            return Observable.error(OnErrorThrowable.addValueAsLastCause(e, file));
        }
    }
});

This work for me:

Login as root:

mysql -u root -p

and then you deactivate the automatic expiration of passwords of all the users:

SET GLOBAL default_password_lifetime = 0;

I found the product key for Visual Studio 2008 Professional under a slightly different key:

HKLM\SOFTWARE\Wow6432Node\Microsoft\MSDN\8.0\Registration\PIDKEY

it was listed without the dashes as stated above.

Late to the party, but the tsbox package is designed to perform conversions like this. To convert your data into a ts-object, you can do:

dta <- data.frame(
  Dates = c("3/14/2013", "3/15/2013", "3/18/2013", "3/19/2013"),
  Bajaj_close = c(1854.8, 1850.3, 1812.1, 1835.9),
  Hero_close = c(1669.1, 1684.45, 1690.5, 1645.6)
)

dta
#>       Dates Bajaj_close Hero_close
#> 1 3/14/2013      1854.8    1669.10
#> 2 3/15/2013      1850.3    1684.45
#> 3 3/18/2013      1812.1    1690.50
#> 4 3/19/2013      1835.9    1645.60

library(tsbox)
ts_ts(ts_long(dta))
#> Time Series:
#> Start = 2013.1971293045 
#> End = 2013.21081883954 
#> Frequency = 365.2425 
#>          Bajaj_close Hero_close
#> 2013.197      1854.8    1669.10
#> 2013.200      1850.3    1684.45
#> 2013.203          NA         NA
#> 2013.205          NA         NA
#> 2013.208      1812.1    1690.50
#> 2013.211      1835.9    1645.60

It automatically parses the dates, detects the frequency and makes the missing values at the weekends explicit. With ts_<class>, you can convert the data to any other time series class.

If you can add another wrapping div "block3" you could do something like this.

 <html>
      <head>
      <style type="text/css">
      .block1 {color:red;width:120px;border:1px solid green; height: 100px;}
      .block3 {float:left; width:10px;}
      .block2 {color:blue;width:70px;border:2px solid black;position:relative;float:right;}
      </style>
      </head>

    <body>
    <div class='block1'>

        <div class='block3'>
            <p>text1</p>
            <p>text2</p>
        </div>

        <div class='block2'>block2</DIV>

    </div>

    </body>
    </html>

public static class StringExtensions
{
    public static bool Contains(this string s, params string[] predicates)
    {
        return predicates.All(s.Contains);
    }
}

string d = "You hit someone for 50 damage";
string a = "damage";
string b = "someone";
string c = "you";

if (d.Contains(a, b))
{
    Console.WriteLine("d contains a and b");
}

I was using spring boot, and for me upgrading the version from 1.4.0.RELEASE to 1.5.6.RELEASE solved this issue.

I found this nice and easy-to-follow guide on how to download the GIT source and compile it yourself (and install it). If the accepted answer does not give you the version you want, try the following instructions:

http://tecadmin.net/install-git-2-0-on-centos-rhel-fedora/

(And pasted/reformatted from above source in case it is removed later)

Step 1: Install Required Packages

Firstly we need to make sure that we have installed required packages on your system. Use following command to install required packages before compiling Git source.

# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
# yum install  gcc perl-ExtUtils-MakeMaker

Step 2: Uninstall old Git RPM

Now remove any prior installation of Git through RPM file or Yum package manager. If your older version is also compiled through source, then skip this step.

# yum remove git

Step 3: Download and Compile Git Source

Download git source code from kernel git or simply use following command to download Git 2.5.3.

# cd /usr/src
# wget https://www.kernel.org/pub/software/scm/git/git-2.5.3.tar.gz
# tar xzf git-2.5.3.tar.gz

After downloading and extracting Git source code, Use following command to compile source code.

# cd git-2.5.3
# make prefix=/usr/local/git all
# make prefix=/usr/local/git install
# echo 'pathmunge /usr/local/git/bin/' > /etc/profile.d/git.sh 
# chmod +x /etc/profile.d/git.sh
# source /etc/bashrc

Step 4. Check Git Version

On completion of above steps, you have successfully install Git in your system. Use the following command to check the git version

# git --version

git version 2.5.3

I also wanted to add that the "Getting Started" guide at the GIT website also includes instructions on how to download and compile it yourself:

http://git-scm.com/book/en/v2/Getting-Started-Installing-Git

Windows has two different settings in which priority is established. There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings.

To change the priority of the connections:

• Open your Adapter Settings (Control Panel\Network and Internet\Network Connections)
• Click Alt to pull up the menu bar
• Select Advanced -> Advanced Settings
• Change the order of the connections so that the connection you want to have priority is top on the list

Give the form an id, and then:

document.getElementById("yourFormId").submit();

Best practice would probably be to give your link an id too, and get rid of the event handler:

document.getElementById("yourLinkId").onclick = function() {
    document.getElementById("yourFormId").submit();
}

1. As other stated, it is not needed for C, but for C++.

2. Including the cast may allow a C program or function to compile as C++.

3. In C it is unnecessary, as void * is automatically and safely promoted to any other pointer type.

4. But if you cast then, it can hide an error if you forgot to include stdlib.h. This can cause crashes (or, worse, not cause a crash until way later in some totally different part of the code).

   Because stdlib.h contains the prototype for malloc is found. In the absence of a prototype for malloc, the standard requires that the C compiler assumes malloc returns an int. If there is no cast, a warning is issued when this integer is assigned to the pointer; however, with the cast, this warning is not produced, hiding a bug.

xcopy "C:\SomeFolderName" "D:\SomeFolderName" /h /i /c /k /e /r /y

Use the above command. It will definitely work.

In this command data will be copied from c:\ to D:\, even folders and system files as well. Here's what the flags do:

• /h copies hidden and system files also
• /i if destination does not exist and copying more than one file, assume that destination must be a directory
• /c continue copying even if error occurs
• /k copies attributes
• /e copies directories and subdirectories, including empty ones
• /r overwrites read-only files
• /y suppress prompting to confirm whether you want to overwrite a file

Indeed 465 works and the exception that you're getting is may be due to the un open SMTP port 25. By default the port number is 25. Yet you can configure it using the mail agent that is available as open source - Mercury

For simplicity, just use the following configuration and you'll be fine.

// Setup your mail server
props.put("mail.smtp.host", SMTP_HOST); 
props.put("mail.smtp.user",FROM_NAME);
props.put("mail.smtp.ssl.enable", "true");
props.put("mail.smtp.port", "25");
props.put("mail.debug", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.EnableSSL.enable","true");
props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");  
props.setProperty("mail.smtp.socketFactory.fallback", "false");  
props.setProperty("mail.smtp.port", "465");  
props.setProperty("mail.smtp.socketFactory.port", "465");

For even more: check out the complete working example from scratch here

There is also pybind11, which is like a lightweight version of Boost.Python and compatible with all modern C++ compilers:

https://pybind11.readthedocs.io/en/latest/

For checking complete changes:

  git diff <commit_Id_1> <commit_Id_2>

For checking only the changed/added/deleted files:

  git diff <commit_Id_1> <commit_Id_2> --name-only

NOTE: For checking diff without commit in between, you don't need to put the commit ids.

This looks like a permission problem. I suggest running processMonitor to determine what permissions are needed.

tl;dr

Standard ISO 8601 format is used by your input string.

Instant.parse ( "2011-08-12T20:17:46.384Z" ) 

ISO 8601

This format is defined by the sensible practical standard, ISO 8601.

The T separates the date portion from the time-of-day portion. The Z on the end means UTC (that is, an offset-from-UTC of zero hours-minutes-seconds). The Z is pronounced “Zulu”.

java.time

The old date-time classes bundled with the earliest versions of Java have proven to be poorly designed, confusing, and troublesome. Avoid them.

Instead, use the java.time framework built into Java 8 and later. The java.time classes supplant both the old date-time classes and the highly successful Joda-Time library.

The java.time classes use ISO 8601 by default when parsing/generating textual representations of date-time values.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds. That class can directly parse your input string without bothering to define a formatting pattern.

Instant instant = Instant.parse ( "2011-08-12T20:17:46.384Z" ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

Actually, it is as simple as setting major and minor separately:

In [9]: plot([23, 456, 676, 89, 906, 34, 2345])
Out[9]: [<matplotlib.lines.Line2D at 0x6112f90>]

In [10]: yscale('log')

In [11]: grid(b=True, which='major', color='b', linestyle='-')

In [12]: grid(b=True, which='minor', color='r', linestyle='--')

The gotcha with minor grids is that you have to have minor tick marks turned on too. In the above code this is done by yscale('log'), but it can also be done with plt.minorticks_on().

No, what you are looking for would be called a parent selector. CSS has none; they have been proposed multiple times but I know of no existing or forthcoming standard including them. You are correct that you would need to use something like jQuery or use additional class annotations to achieve the effect you want.

Here are some similar questions with similar results:

• Is there a CSS parent selector?
• CSS Parent/Ancestor Selector
• Complex CSS selector for parent of active child

A picture's worth a thousand words:

>>> class c:
        pass
o = c()
>>> setattr(o, "foo", "bar")
>>> o.foo
'bar'
>>> getattr(o, "foo")
'bar'
