You can try:

Open sql file by text editor find and replace all

utf8mb4 to utf8

Import again.

I have also faced the same issue, The solution for it is : the file for which you are getting the error is probably a duplicated file of the actual file with another version. So just the removal of a particular file on which errors are thrown can resolve the issue.

Yeah install the 32 bit version of the Java SE SDK (or any of the combinations). That should help solve your problem.

Michael Krelin's answer is close is not entirely safe, since it can be wrong in rare situations. The problem is that intervals in PostgreSQL do not have context with regards to things like daylight savings. Intervals store things internally as months, days, and seconds. Months aren't an issue in this case since subtracting two timestamps just use days and seconds but 'days' can be a problem.

If your subtraction involves daylight savings change-overs, a particular day might be considered 23 or 25 hours respectively. The interval will take that into account, which is useful for knowing the amount of days that passed in the symbolic sense but it would give an incorrect number of the actual hours that passed. Epoch on the interval will just multiply all days by 24 hours.

For example, if a full 'short' day passes and an additional hour of the next day, the interval will be recorded as one day and one hour. Which converted to epoch/3600 is 25 hours. But in reality 23 hours + 1 hour should be a total of 24 hours.

So the safer method is:

(EXTRACT(EPOCH FROM current_timestamp) - EXTRACT(EPOCH FROM somedate))/3600

As Michael mentioned in his follow-up comment, you'll also probably want to use floor() or round() to get the result as an integer value.

This is by far the easiest way I have found to use javascript regex to check phone number format. this particular example checks if it is a 10 digit number.

<input name="phone" pattern="^\d{10}$" type="text" size="50">

The input field gets flagged when submit button is clicked if the pattern doesn't match the value, no other css or js required.

Use the strtotime function:

Example:

 $date = "25 december 2009";
 $my_date = date('m/d/y', strtotime($date));
 echo $my_date;

alter table your_table
alter column LoginDate datetime;

Here's a complete example of how it can be done. However you need flashback query privileges on the child table.

Here's the setup.

create table parent_tab
  (parent_id number primary key,
  val varchar2(20));

create table child_tab
    (child_id number primary key,
    parent_id number,
    child_val number,
     constraint child_par_fk foreign key (parent_id) references parent_tab);

insert into parent_tab values (1,'Red');
insert into parent_tab values (2,'Green');
insert into parent_tab values (3,'Blue');
insert into parent_tab values (4,'Black');
insert into parent_tab values (5,'White');

insert into child_tab values (10,1,100);
insert into child_tab values (20,3,100);
insert into child_tab values (30,3,100);
insert into child_tab values (40,4,100);
insert into child_tab values (50,5,200);

commit;

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

Now delete a subset of the children (ones with parents 1,3 and 4 - but not 5).

delete from child_tab where child_val = 100;

Then get the parent_ids from the current COMMITTED state of the child_tab (ie as they were prior to your deletes) and remove those that your session has NOT deleted. That gives you the subset that have been deleted. You can then delete those out of the parent_tab

delete from parent_tab
where parent_id in
  (select parent_id from child_tab as of scn dbms_flashback.get_system_change_number
  minus
  select parent_id from child_tab);

'Green' is still there (as it didn't have an entry in the child table anyway) and 'Red' is still there (as it still has an entry in the child table)

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

select * from parent_tab;

It is an exotic/unusual operation, so if i was doing it I'd probably be a bit cautious and lock both child and parent tables in exclusive mode at the start of the transaction. Also, if the child table was big it wouldn't be particularly performant so I'd opt for a PL/SQL solution like Rajesh's.

Here are some instructions on how to initiate a GitHub repository and then push code you've already created to it. The first set of instructions are directly from GitHub.

Source: https://help.github.com/articles/create-a-repo/

1. In the upper-right corner of any page, click, and then click New repository.

2. Create a short, memorable name for your repository. For example, "hello-world".

3. Optionally, add a description of your repository. For example, "My first repository on GitHub."

4. Choose between creating a public or private repository.

5. Initialize this repository with a README.

6. Create repository.

Congratulations! You've successfully created your first repository, and initialized it with a README file.

Now after these steps you will want to push the code on your local computer up to the repository you just created and you do this following these steps:

1. git init (in the root folder where your code is located)

2. git add -A (this will add all the files and folders in your directory to be committed)

3. git commit -am "First Project commit"

4. git remote add origin [email protected]:YourGithubName/your-repo-name.git (you'll find this address on the GitHub repository you just created under "ssh clone URL" on the main page)

5. git push -u origin master

That's it. Your code will now be pushed up to GitHub. Now every time you want to keep pushing code that has changed just do.

1. git commit -m "New changes"

2. git push origin master (if master is the branch you are working on)

Unfortunately, I found this link which appears to indicate that we cannot cache these locally, therefore making this question moot.

http://support.google.com/enterprise/doc/gme/terms/maps_purchase_agreement.html

4.4 Cache Restrictions. Customer may not pre-fetch, retrieve, cache, index, or store any Content, or portion of the Services with the exception being Customer may store limited amounts of Content solely to improve the performance of the Customer Implementation due to network latency, and only if Customer does so temporarily, securely, and in a manner that (a) does not permit use of the Content outside of the Services; (b) is session-based only (once the browser is closed, any additional storage is prohibited); (c) does not manipulate or aggregate any Content or portion of the Services; (d) does not prevent Google from accurately tracking Page Views; and (e) does not modify or adjust attribution in any way.

So it appears we cannot use Google map tiles offline, legally.

The fix was at the accepted answer. Yet if someone wants to know why it worked and why the implementation in the SO question didn't work,

First, functions are first class objects in JavaScript. That means they are treated like any other variable. Function can be passed as an argument to other functions, can be returned by another function and can be assigned as a value to a variable. Read more here.

So we use that variable to invoke the function by adding parentheses () at the end.

One thing, If you have a function that returns a funtion and you just need to call that returned function, you can just have double paranthesis when you call the outer function ()().

I believe:

String.Format("{0:0.00}",Sale);

Should do it.

See Link String Format Examples C#

You need the :not() selector:

$('div[class^="first-"]:not(.first-bar)')

or, alternatively, the .not() method:

$('div[class^="first-"]').not('.first-bar');

You don't need the div's.

HTML:

<div class="nav3" style="height:705px;">
    <a href="http://www.facebook.com/" class="icons"><img src="images/facebook.png"></a>
    <a href="https://twitter.com" class="icons"><img src="images/twitter.png"></a>
</div>

CSS:

.nav3 {
    background-color: #E9E8C7;
    height: auto;
    width: 150px;
    float: left;
    padding-left: 20px;
    font-family: Arial, Helvetica, sans-serif;
    font-size: 12px;
    color: #333333;
    padding-top: 20px;
    padding-right: 20px;
}

.icons{
    display:inline-block;
    width: 64px; 
    height: 64px; 
   }

 a.icons:hover {
     background: #C93;
 }

Another method through re module. It does the reverse operation of matching all the words instead of spitting the whole sentence by space.

>>> import re
>>> s = "many   fancy word \nhello    \thi"
>>> re.findall(r'\S+', s)
['many', 'fancy', 'word', 'hello', 'hi']

Above regex would match one or more non-space characters.

To make background transparent, set shape as None. See the image below:

EDIT:

For Android Studio 3.0, you can set it from Legacy Tab

By using just jQuery, you cannot avoid a server call.

However, to achieve this result, I'm using Downloadify, which lets me save files without having to make another server call. Doing this reduces server load and makes a good user experience.

To get a proper CSV you just have to take out all the unnecessary tags and put a ',' between the data.

I came across this problem recently in a very similar situation: Met all requirements as the top-rated answer listed but still got the wrong result.

So I looked at my dependencies and found I was missing some of them. I corrected it by adding the missing dependencies.

I was using hibernate, the required dependencies were:

*Snapshot taken in class "Spring & Hibernate for Beginners" @ Udemy

Dart http's implementation process the bytes thanks to that "charset=utf-8", so i'm sure several implementations out there supports this, to avoid the "latin-1" fallback charset when reading the bytes from the response. In my case, I totally lose format on the response body string, so I have to do the bytes encoding manually to utf8, or add that header "inner" parameter on my server's API response.

Although this code is likely beyond the understanding of a novice, it can be done in one line using a regex with positive and negative look-aheads:

boolean ok = 
    password.matches("^(?=.*[A-Z])(?=.*[!@#$%^&*])(?=.*\\d)(?!.*(AND|NOT)).*[a-z].*");

I got the answer...this seems to be working perfectly fine

public int[] test ( int[]b )
{
    ArrayList<Integer> l = new ArrayList<Integer>();
    Object[] returnArrayObject = l.toArray();
    int returnArray[] = new int[returnArrayObject.length];
    for (int i = 0; i < returnArrayObject.length; i++){
         returnArray[i] = (Integer)  returnArrayObject[i];
    }

    return returnArray;
}

This Gist by Eldon McGuinness is by far the most complete implementation of a JavaScript query string parser that I've seen so far.

Unfortunately, it's written as a jQuery plugin.

I rewrote it to vanilla JS and made a few improvements :

function parseQuery(str) {_x000D_

  while (qs.indexOf("&&") != -1) {_x000D_
    qs = qs.replace(/&&/g, '&');_x000D_
  }_x000D_
  qs = qs.replace(/([\&]+$)/, '');_x000D_
  // Break the querystring into parts_x000D_
  qs = qs.split("&");_x000D_
  // Build the querystring object_x000D_
  for (var i = 0; i < qs.length; i++) {_x000D_
    var qi = qs[i].split("=");_x000D_
    qi = qi.map(function(n) {_x000D_
      return decodeURIComponent(n)_x000D_
    });_x000D_

EDIT: I tried using a CTE on my previous answer which was incorrect, as pointed out by @bummi. This option should work instead:

Here's one option using a CROSS APPLY, to kind of work around this problem:

SELECT st.Value, Constants.CONSTANT_ONE, Constants.CONSTANT_TWO
FROM SomeTable st
CROSS APPLY (
    SELECT 'Value1' AS CONSTANT_ONE,
           'Value2' AS CONSTANT_TWO
) Constants

These won't be the case in Safari or Chrome from iOS - only within the browser inside the Facebook app.

(I'm getting iPhone9 too though - not quite sure what that is!)

The easiest would be using a foreach:

foreach(GridViewRow row in GridView2.Rows)
{
    // here you'll get all rows with RowType=DataRow
    // others like Header are omitted in a foreach
}

Edit: According to your edits, you are accessing the column incorrectly, you should start with 0:

foreach(GridViewRow row in GridView2.Rows)
{
    for(int i = 0; i < GridView2.Columns.Count; i++)
    {
        String header = GridView2.Columns[i].HeaderText;
        String cellText = row.Cells[i].Text;
    }
}

Prior to running python, type cd in the commmand line, and it will tell you the directory you are currently in. When python runs, it can only access files in this directory. hello.py needs to be in this directory, so you can move hello.py from its existing location to this folder as you would move any other file in Windows or you can change directories and run python in the directory hello.py is.

Edit: Python cannot access the files in the subdirectory unless a path to it provided. You can access files in any directory by providing the path. python C:\Python27\Projects\hello.p

I had the same issue for two days now. Disabled SELinux and everything but nothing helped. And I realize it just may not be smart to disable security for a small fix. Then I came upon this article - http://wiki.centos.org/HowTos/SELinux/ that explains how SELinux operates. So this is what I did and it fixed my problem.

1. Enable access to your main phpmyadmin directory by going to parent directory of phpmyadmin (mine was html) and typing:

   chcon -v --type=httpd_sys_content_t phpmyadmin
   

2. Now do the same for the index.php by typing:

   chcon -v --type=httpd_sys_content_t phpmyadmin/index.php
   

   Now go back and check if you are getting a blank page. If you are, then you are on the right track. If not, go back and check your httpd.config directory settings. Once you do get the blank page with no warnings, proceed.

3. Now recurse through all the files in your phpmyadmin directory by running:

   chron -Rv --type=httpd_sys_content_t phpmyadmin/*
   

Go back to your phpmyadmin page and see if you are seeing what you need. If you are running a web server that's accessible from outside your network, make sure that you reset your SELinux to the proper security level. Hope this helps!

Try with Shadow( Like border ) + Border

border-bottom: 5px solid #fff;
box-shadow: 0 5px 0 #ffbf0e;

If you want a list of strings containing your string:

var newList = myList.Where(x => x.Contains(myString)).ToList();

Another option is to use Linq FirstOrDefault

var element = myList.Where(x => x.Contains(myString)).FirstOrDefault();

Keep in mind that Contains method is case sensitive.

Use position:fixed; and set the top:0;left:0;right:0;height:100px; and you should be able to have it "stick" to the top of the page.

<div style="position:fixed;top:0;left:0;right:0;height:100px;">Some buttons</div>

In my windows 10 Enterprise edition os this code works fine: (suppose for environment namely testenv)

conda env remove --name testenv

you can also do :

string.Format("{0:C}", amt)

You can use

1. Go browser & type localhost/phpmyadmin/
2. Go to User accounts
3. Edit privileges from marked bellow image in last options root->localhost-> Yes->ALL PRIVILEGES->Yes-> Edit privileges

Here is image like bellow

4. you can click on Edit privileges last option above image
5. Then you can click on Change password. It shows enter password screen
6. Enter your password & retype your password in password the field
7. Then click on GO
8. Then Go to XAMPP->xamppfiles->config.inc.php
9. Open config.inc.php file & go to /* Authentication type */ sections

10. change config to cookie & type your password in ' ' in password like bellow

    $cfg['Servers'][$i]['auth_type'] = 'cookie';
    $cfg['Servers'][$i]['user'] = 'root';
    $cfg['Servers'][$i]['password'] = 'your password';
    

11. Then save & type on browser localhost/phpmyadmin/

12. Enter your given password & enjoy

If you're using IntelliJ 13 with SVN 1.8, you have to install SVN command line client. Please see more information here:

Unlike its earlier versions, Subversion 1.8 support uses the native command line client instead of SVNKit to run commands. This approach is more flexible and makes the support of upcoming versions much easier. Now, IntelliJ IDEA offers different integration options for each specific Subversion:

1.6 – SVNKit only

1.7 – SVNKit and command line client

1.8 – Command line client only

In the specific case of x68 to x68_64, the 64 bit program will be about the same size, if not slightly smaller, use a bit more memory, and run faster. Mostly this is because x86_64 doesn't just have 64 bit registers, it also has twice as many. x86 does not have enough registers to make compiled languages as efficient as they could be, so x86 code spends a lot of instructions and memory bandwidth shifting data back and forth between registers and memory. x86_64 has much less of that, and so it takes a little less space and runs faster. Floating point and bit-twiddling vector instructions are also much more efficient in x86_64.

In general, though, 64 bit code is not necessarily any faster, and is usually larger, both for code and memory usage at runtime.

Sending an HTTP POST request on iOS (Objective c):

-(NSString *)postexample{

// SEND POST
NSString *url = [NSString stringWithFormat:@"URL"];
NSString *post = [NSString stringWithFormat:@"param=value"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];


NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:@"POST"];
[request setURL:[NSURL URLWithString:url]];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

NSError *error = nil;
NSHTTPURLResponse *responseCode = nil;

//RESPONDE DATA 
NSData *oResponseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&responseCode error:&error];

if([responseCode statusCode] != 200){
    NSLog(@"Error getting %@, HTTP status code %li", url, (long)[responseCode statusCode]);
    return nil;
}

//SEE RESPONSE DATA
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Response" message:[[NSString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];

return [[NSString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
}

You need to use ECHO. Also, put the quotes around the entire file path if it contains spaces.

One other note, use > to overwrite a file if it exists or create if it does not exist. Use >> to append to an existing file or create if it does not exist.

Overwrite the file with a blank line:

ECHO.>"C:\My folder\Myfile.log"

Append a blank line to a file:

ECHO.>>"C:\My folder\Myfile.log"

Append text to a file:

ECHO Some text>>"C:\My folder\Myfile.log"

Append a variable to a file:

ECHO %MY_VARIABLE%>>"C:\My folder\Myfile.log"

One way to order by positive integers, when they are stored as varchar, is to order by the length first and then the value:

order by len(registration_no), registration_no

This is particularly useful when the column might contain non-numeric values.

Note: in some databases, the function to get the length of a string might be called length() instead of len().

Date arithmetic is not needed if you just want to display the same timestamp in different timezones:

$format = "M d, Y h:ia";
$timestamp = gmdate($format);

date_default_timezone_set("UTC");
$utc_datetime = date($format, $timestamp);

date_default_timezone_set("America/Guayaquil");
$local_datetime = date($format, $timestamp);

Simple:

$url = "http://php.net/manual/en/function.preg-match.php";
preg_match("/http:\/\/php\.net(.+)\.php/", $url, $matches);
echo $matches[1];

$matches[0] is your full URL, $matches[1] is the part you want.

From what I've learned with Alex Cowan in the course Continuous Delivery & DevOps, CI and CD is part of a product pipeline that consists in the time it goes from an Observations to a Released Product.

From Observations to Designs the goal is to get high quality testable ideas. This part of the process is considered Continuous Design.

What happens after, when we go from the Code onwards, it's considered a Continuous Delivery capability whose aim is to execute the ideas and release to the customer very fast (you can read Jez Humble's book Continuous Delivery: Reliable Software Releases through Build, Test, and Deployment Automation for more details). The following pipeline explains which steps Continuous Integration (CI) and Continuous Delivery (CD) consist of.

Continuous Integration, as Mattias Petter Johansson explains,

is when a software team has habit of doing multiple merges per day and they have an automated verification system in place to check those merges for problems.

(you can watch the following two videos for a more pratical overview using CircleCI - Getting started with CircleCI - Continuous Integration P2 and Running CircleCI on Pull Request).

One can specify the CI/CD pipeline as following, that goes from New Code to a released Product.

The first three steps have to do with Tests, extending the boundary of what's being tested.

Continuous Deployment, on the other hand, is to handle the Deployment automatically. So, any code commit that passes the automated testing phase is automatically released into the production.

Note: This isn't necessarily what your pipelines should look like, yet they can serve as reference.

        org.json.JSONArray o1 = new org.json.JSONArray("[{\"one\":[],\"two\":\"abc\"}]");
        org.json.JSONArray o2 = new org.json.JSONArray("[{\"three\":[1,2],\"four\":\"def\"}]");


        resultantJson.addAll(o1.toList());
        resultantJson.addAll(o2.toList());

Depending on the actual value and what exception fits best:

• ArgumentException (something is wrong with the value)

• ArgumentNullException (the argument is null while this is not allowed)

• ArgumentOutOfRangeException (the argument has a value outside of the valid range)

If this is not precise enough, just derive your own exception class from ArgumentException.

Yoooder's answer enlightened me. An input is invalid if it is not valid at any time, while an input is unexpected if it is not valid for the current state of the system. So in the later case an InvalidOperationException is a reasonable choice.

In my case, the content type response headers was Content-Type: text/plain. So, I've read the data from Buffer like:

let data = [];
stream.on('data', (chunk) => {
 console.log(Buffer.from(chunk).toString())
 data.push(Buffer.from(chunk).toString())
});

You can also manually tag the column with a contrasts attribute, which seems to be respected by the regression functions:

contrasts(df$factorcol) <- contr.treatment(levels(df$factorcol),
   base=which(levels(df$factorcol) == 'RefLevel'))

If you try to decrypt PKCS5-padded data with the wrong key, and then unpad it (which is done by the Cipher class automatically), you most likely will get the BadPaddingException (with probably of slightly less than 255/256, around 99.61%), because the padding has a special structure which is validated during unpad and very few keys would produce a valid padding.

So, if you get this exception, catch it and treat it as "wrong key".

This also can happen when you provide a wrong password, which then is used to get the key from a keystore, or which is converted into a key using a key generation function.

Of course, bad padding can also happen if your data is corrupted in transport.

That said, there are some security remarks about your scheme:

• For password-based encryption, you should use a SecretKeyFactory and PBEKeySpec instead of using a SecureRandom with KeyGenerator. The reason is that the SecureRandom could be a different algorithm on each Java implementation, giving you a different key. The SecretKeyFactory does the key derivation in a defined manner (and a manner which is deemed secure, if you select the right algorithm).

• Don't use ECB-mode. It encrypts each block independently, which means that identical plain text blocks also give always identical ciphertext blocks.

  Preferably use a secure mode of operation, like CBC (Cipher block chaining) or CTR (Counter). Alternatively, use a mode which also includes authentication, like GCM (Galois-Counter mode) or CCM (Counter with CBC-MAC), see next point.

• You normally don't want only confidentiality, but also authentication, which makes sure the message is not tampered with. (This also prevents chosen-ciphertext attacks on your cipher, i.e. helps for confidentiality.) So, add a MAC (message authentication code) to your message, or use a cipher mode which includes authentication (see previous point).

• DES has an effective key size of only 56 bits. This key space is quite small, it can be brute-forced in some hours by a dedicated attacker. If you generate your key by a password, this will get even faster. Also, DES has a block size of only 64 bits, which adds some more weaknesses in chaining modes. Use a modern algorithm like AES instead, which has a block size of 128 bits, and a key size of 128 bits (for the standard variant).

In my tests many of the approaches described here fail, I think because they rely on entries in the Windows registry that turn out to be not reliably present, depending on Office version, how it was installed etc. So a different approach is to not use the registry at all (Ok, so strictly that makes it not an answer to the question as posed), but instead write a script that:

1. Instantiates Excel
2. Adds a workbook to that Excel instance
3. Adds a VBA module to that workbook
4. Injects a small VBA function that returns the bitness of Office
5. Calls that function
6. Cleans up

Here's that approach implemented in VBScript:

Function OfficeBitness()

    Dim VBACode, Excel, Wb, Module, Result

    VBACode = "Function Is64bit() As Boolean" & vbCrLf & _
              "#If Win64 Then" & vbCrLf & _
              "    Is64bit = True" & vbCrLf & _
              "#End If" & vbCrLf & _
              "End Function"

    On Error Resume Next
    Set Excel = CreateObject("Excel.Application")
    Excel.Visible = False
    Set Wb = Excel.Workbooks.Add
    Set Module = Wb.VBProject.VBComponents.Add(1)
    Module.CodeModule.AddFromString VBACode
    Result = Excel.Run("Is64bit")
    Set Module = Nothing
    Wb.Saved = True
    Wb.Close False
    Excel.Quit
    Set Excel = Nothing
    On Error GoTo 0
    If IsEmpty(Result) Then
        OfficeBitness = 0 'Alternatively raise an error here?
    ElseIf Result = True Then
        OfficeBitness = 64
    Else
        OfficeBitness = 32
    End If

End Function

PS. This approach runs more slowly than others here (about 2 seconds on my PC) but it might turn out to be more reliable across different installations and Office versions.

After some months, I've realised there may be a simpler approach, though still one that instantiates an Excel instance. The VBScript is:

Function OfficeBitness()
    Dim Excel
    Set Excel = CreateObject("Excel.Application")
    Excel.Visible = False
    If InStr(Excel.OperatingSystem,"64") > 0 Then
        OfficeBitness = 64
    Else
        OfficeBitness = 32
    End if
    Excel.Quit
    Set Excel = Nothing
End Function

This relies on the fact that Application.OperatingSystem, when called from 32-bit Excel on 64-bit Windows returns Windows (32-bit) NT 10.00 or at least it does on my PC. But that's not mentioned in the docs.

The Java 5 documentation also recommends using this method for the same purpose.

This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time.

Java 5 API Doc

A quick example:

List<List<string>> myList = new List<List<string>>();
myList.Add(new List<string> { "a", "b" });
myList.Add(new List<string> { "c", "d", "e" });
myList.Add(new List<string> { "qwerty", "asdf", "zxcv" });
myList.Add(new List<string> { "a", "b" });

// To iterate over it.
foreach (List<string> subList in myList)
{
    foreach (string item in subList)
    {
        Console.WriteLine(item);
    }
}

Is that what you were looking for? Or are you trying to create a new class that extends List<T> that has a member that is a `List'?

This is a block element, in order for it to be able to receive focus, you need to add tabindex attribute to it, as in

<div id="myID" tabindex="1"></div>

Tabindex will allow this element to receive focus. Use tabindex="-1" (or indeed, just get rid of the attribute alltogether) to disallow this behaviour.

And then you can simply

if ($("#myID").is(":focus")) {...}

Or use the

$(document.activeElement)

As been suggested previously.

Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this:

1. Add, if not already there, a row of "column Musicians" to the spreadsheet. That is, if you have data in columns such as:

   Rory Gallagher      Guitar
   Gerry McAvoy        Bass
   Rod de'Ath          Drums
   Lou Martin          Keyboards
   Donkey Kong Sioux   Self-Appointed Semi-official Stomper
   

   Note: you might want to add "Musician" and "Instrument" in row 0 (you might have to insert a row there)

2. Save the file as a CSV file.

3. Copy the contents of the CSV file to the clipboard

4. Go to http://www.convertcsv.com/csv-to-json.htm

5. Verify that the "First row is column names" checkbox is checked

6. Paste the CSV data into the content area

7. Mash the "Convert CSV to JSON" button

   With the data shown above, you will now have:

   [
     {
       "MUSICIAN":"Rory Gallagher",
       "INSTRUMENT":"Guitar"
     },
     {
       "MUSICIAN":"Gerry McAvoy",
       "INSTRUMENT":"Bass"
     },
     {
       "MUSICIAN":"Rod D'Ath",
       "INSTRUMENT":"Drums"
     },
     {
       "MUSICIAN":"Lou Martin",
       "INSTRUMENT":"Keyboards"
     }
     {
       "MUSICIAN":"Donkey Kong Sioux",
       "INSTRUMENT":"Self-Appointed Semi-Official Stomper"
     }
   ]
   

   With this simple/minimalistic data, it's probably not required, but with large sets of data, it can save you time and headache in the proverbial long run by checking this data for aberrations and abnormalcy.

8. Go here: http://jsonlint.com/

9. Paste the JSON into the content area

10. Pres the "Validate" button.

If the JSON is good, you will see a "Valid JSON" remark in the Results section below; if not, it will tell you where the problem[s] lie so that you can fix it/them.

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

I figured out what it was! When I cleared the fields using the each() method, it also cleared the hidden field which the php needed to run:

if ($_POST['action'] == 'addRunner') 

I used the :not() on the selection to stop it from clearing the hidden field.

According to Cormen et al. Introduction to Algorithms (Appendix B.5.3), the depth of a node X in a tree T is defined as the length of the simple path (number of edges) from the root node of T to X. The height of a node Y is the number of edges on the longest downward simple path from Y to a leaf. The height of a tree is defined as the height of its root node.

Note that a simple path is a path without repeat vertices.

The height of a tree is equal to the max depth of a tree. The depth of a node and the height of a node are not necessarily equal. See Figure B.6 of the 3rd Edition of Cormen et al. for an illustration of these concepts.

I have sometimes seen problems asking one to count nodes (vertices) instead of edges, so ask for clarification if you're not sure you should count nodes or edges during an exam or a job interview.

When wrapping a pointer in a unique_ptr you cannot have multiple copies of unique_ptr. The shared_ptr holds a reference counter which count the number of copies of the stored pointer. Each time a shared_ptr is copied, this counter is incremented. Each time a shared_ptr is destructed, this counter is decremented. When this counter reaches 0, then the stored object is destroyed.

The easiest might be:

Array(1, 2, 3) :+ 4

Actually, Array can be implcitly transformed in a WrappedArray

a,b=[],[]
n=int(input("Provide me size of squre matrix row==column : "))
for i in range(n):
   for j in range(n):
      b.append(int(input()))
    a.append(b)
    print("Here your {} column {}".format(i+1,a))
    b=[]
for m in range(n):
    print(a[m])

works perfectly

Try Math.log(x) / Math.log(2)

The number of column parameters in your insert query is 9, but you've only provided 8 values.

INSERT INTO dbname (id, Name, Description, shortDescription, Ingredients, Method, Length, dateAdded, Username) VALUES ('', '%s', '%s', '%s', '%s', '%s', '%s', '%s')

The query should omit the "id" parameter, because it is auto-generated (or should be anyway):

INSERT INTO dbname (Name, Description, shortDescription, Ingredients, Method, Length, dateAdded, Username) VALUES ('', '%s', '%s', '%s', '%s', '%s', '%s', '%s')

Experienced this myself when using requests:

This is extremely insecure; use only as a last resort! (See rdlowrey's comment.)

requests.get('https://github.com', verify=True)

Making that verify=False did the trick for me.

        present(alertPrompt, animated: true, completion: nil)
    }

}

Second part is the extension of our UIViewController subclass for AVCaptureMetadataOutputObjectsDelegate where we catch the captured outputs.

extension BarCodeScannerViewController: AVCaptureMetadataOutputObjectsDelegate {

    func metadataOutput(_ output: AVCaptureMetadataOutput, didOutput metadataObjects: [AVMetadataObject], from connection: AVCaptureConnection) {
        handleCapturedOutput(metadataObjects: metadataObjects)
    }

}

Update for Swift 4.2

.UIApplicationWillEnterForegroundchanges as UIApplication.willEnterForegroundNotification.

Yes, ensure is called in any circumstances. For more information see "Exceptions, Catch, and Throw" of the Programming Ruby book and search for "ensure".

list = [1,1,1,0]
print(any(list)) # will return True because there is  1 or True exists
print(all(list)) # will return False because there is a 0 or False exists
return all(a % i for i in range(3, int(a ** 0.5) + 1)) # when number is divisible it will return False else return True but the whole statement is False .

Or you can do this:

MyString[0];

java -jar fernflower.jar -hdc=0 -dgs=1 -rsy=1 -lit=1 c:\Temp\binary\ -e=c:\Java\rt.jar c:\Temp\source\

Be aware that if you pass it a ".jar" file for the source, it will create another ".jar" file in the destination, however, within the new ".jar" file, the files will be .java instead of .class files (it doesn't explode the jar).

UPDATE

People ask me: How do I get the fernflower.jar?

If you have any IntelliJ product installed, chances are that you already have the Fernflower decompiler on your computer. IntelliJ IDEA comes with Java Bytecode Decompiler plugin (bundled) which is a modern extension of Fernflower.

1. Locate the file in ${IntelliJ_INSTALL_DIR}\plugins\java-decompiler\lib\java-decompiler.jar (example: C:\Program Files\JetBrains\IntelliJ IDEA 2018\plugins\java-decompiler\lib).
2. Copy it somewhere and rename to fernflower.jar (optional).

3. This JAR is not executable, so we can't run it using java -jar. However something like this works:

   java -cp fernflower.jar org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler [<source>]+ <destination>
   

   org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler is the class that contains the main method to run the decompiler.

   Example:

   mkdir output_src
   java -cp fernflower.jar org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler -hdc=0 -dgs=1 -rsy=1 -lit=1 ./input.jar ./output_src
   

If you don't have IntelliJ products installed, either download it now (available on jetbrains.com) or make your own decompiler executable from sources (available on Github).

In the .content tab in CSS change it to position:absolute. Otherwise, the page rendered won't be scrollable.

It is now the first example in the Jersey Client documentation

Example 5.1. POST request with form parameters

Client client = ClientBuilder.newClient();
WebTarget target = client.target("http://localhost:9998").path("resource");

Form form = new Form();
form.param("x", "foo");
form.param("y", "bar");

MyJAXBBean bean =
target.request(MediaType.APPLICATION_JSON_TYPE)
    .post(Entity.entity(form,MediaType.APPLICATION_FORM_URLENCODED_TYPE),
        MyJAXBBean.class);

In javascript you can do it this way

radians = degrees * (Math.PI/180);

degrees = radians * (180/Math.PI);

in some case you can use annotation @Primary.

@Primary
class USA implements Country {}

This way it will be selected as the default autowire candididate, with no need to autowire-candidate on the other bean.

for mo deatils look at Autowiring two beans implementing same interface - how to set default bean to autowire?

There is no need to have two functions within one element, you need just one that calls the other two!

HTML

<a href="#" onclick="my_func()" >click</a>

JavaScript

function my_func() {
    my_func_1();
    my_func_2();
}

To remove tagged images which have not container running, you will have to use a little script:

#!/bin/bash

# remove not running containers
docker rm $(docker ps -f "status=exited" -q)

declare -A used_images

# collect images which has running container
for image in $(docker ps | awk 'NR>1 {print $2;}'); do
    id=$(docker inspect --format="{{.Id}}" $image);
    used_images[$id]=$image;
done

# loop over images, delete those without a container
for id in $(docker images --no-trunc -q); do
    if [ -z ${used_images[$id]} ]; then
        echo "images is NOT in use: $id"
        docker rmi $id
    else
        echo "images is in use:     ${used_images[$id]}"
    fi
done

On Windows, type cd for the working current path.

On Linux, pwd for the current working path.

Both choices refer to what algorithm the identity provider uses to sign the JWT. Signing is a cryptographic operation that generates a "signature" (part of the JWT) that the recipient of the token can validate to ensure that the token has not been tampered with.

• RS256 (RSA Signature with SHA-256) is an asymmetric algorithm, and it uses a public/private key pair: the identity provider has a private (secret) key used to generate the signature, and the consumer of the JWT gets a public key to validate the signature. Since the public key, as opposed to the private key, doesn't need to be kept secured, most identity providers make it easily available for consumers to obtain and use (usually through a metadata URL).

• HS256 (HMAC with SHA-256), on the other hand, involves a combination of a hashing function and one (secret) key that is shared between the two parties used to generate the hash that will serve as the signature. Since the same key is used both to generate the signature and to validate it, care must be taken to ensure that the key is not compromised.

If you will be developing the application consuming the JWTs, you can safely use HS256, because you will have control on who uses the secret keys. If, on the other hand, you don't have control over the client, or you have no way of securing a secret key, RS256 will be a better fit, since the consumer only needs to know the public (shared) key.

Since the public key is usually made available from metadata endpoints, clients can be programmed to retrieve the public key automatically. If this is the case (as it is with the .Net Core libraries), you will have less work to do on configuration (the libraries will fetch the public key from the server). Symmetric keys, on the other hand, need to be exchanged out of band (ensuring a secure communication channel), and manually updated if there is a signing key rollover.

Auth0 provides metadata endpoints for the OIDC, SAML and WS-Fed protocols, where the public keys can be retrieved. You can see those endpoints under the "Advanced Settings" of a client.

The OIDC metadata endpoint, for example, takes the form of https://{account domain}/.well-known/openid-configuration. If you browse to that URL, you will see a JSON object with a reference to https://{account domain}/.well-known/jwks.json, which contains the public key (or keys) of the account.

If you look at the RS256 samples, you will see that you don't need to configure the public key anywhere: it's retrieved automatically by the framework.

I've ran into this topic, because i was struggling with dashed lines too (gnuplot 4.6 patchlevel 0)

If you use:

set termoption dashed

Your posted code will work accordingly.

Related question:
However, if I want to export a png with: set terminal png, this isn't working anymore. Anyone got a clue why?

Turns out, out, gnuplots png export library doesnt support this.
Possbile solutions:

• one can simply export to ps, then convert it with pstopng
• according to @christoph, if you use pngcairo as your terminal (set terminal pngcairo) it will work

A generic answer on how to handle click events with KnockoutJS...

Not a straight up answer to the question as asked, but probably an answer to the question most Googlers landing here have: use the click binding from KnockoutJS instead of onclick. Like this:

function Item(parent, txt) {_x000D_
  var self = this;_x000D_
  _x000D_
  self.doStuff = function(data, event) {_x000D_
    console.log(data, event);_x000D_
    parent.log(parent.log() + "\n  data = " + ko.toJSON(data));_x000D_
  };_x000D_
  _x000D_
  self.doOtherStuff = function(customParam, data, event) {_x000D_
    console.log(data, event);_x000D_
    parent.log(parent.log() + "\n  data = " + ko.toJSON(data) + ", customParam = " + customParam);_x000D_
  };_x000D_
  _x000D_

function RootVm(items) {_x000D_

    self.log(self.log() + "\n  data = " + ko.toJSON(data));_x000D_
  };_x000D_
  _x000D_
  self.items = ko.observableArray([_x000D_
    new Item(self, "John Doe"),_x000D_
    new Item(self, "Marcus Aurelius")_x000D_
  ]);_x000D_
  self.log = ko.observable("Started logging...");_x000D_
}_x000D_
_x000D_
ko.applyBindings(new RootVm());

.parent { background: rgba(150, 150, 200, 0.5); padding: 2px; margin: 5px; }_x000D_

**A note about the actual question...*

The actual question has one interesting bit:

// Uh oh! Modifying the DOM....
place.innerHTML = "somthing"

Don't do that! Don't modify the DOM like that when using an MVVM framework like KnockoutJS, especially not the piece of the DOM that is your own parent. If you would do this the button would disappear (if you replace your parent's innerHTML you yourself will be gone forever ever!).

Instead, modify the View Model in your handler instead, and have the View respond. For example:

function RootVm() {_x000D_
  var self = this;_x000D_
  self.buttonWasClickedOnce = ko.observable(false);_x000D_
  self.toggle = function(data, event) {_x000D_
    self.buttonWasClickedOnce(!self.buttonWasClickedOnce());_x000D_
  };_x000D_
}_x000D_
_x000D_
ko.applyBindings(new RootVm());

<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.0/knockout-min.js"></script>_x000D_
_x000D_
<div>_x000D_
  <div  data-bind="visible: !buttonWasClickedOnce()">_x000D_
    <button data-bind="click: toggle">Toggle!</button>_x000D_
  </div>_x000D_
  <div data-bind="visible: buttonWasClickedOnce">_x000D_
    Can be made visible with toggle..._x000D_
    <button data-bind="click: toggle">Untoggle!</button>_x000D_
  </div>_x000D_
</div>

In C# 7 we can use tuples to accomplish this:

public List<(int SomeVariable, string AnotherVariable)> TheMethod(SomeParameter)
{
  using (MyDC TheDC = new MyDC())
  {
     var TheQueryFromDB = (....
                       select new { SomeVariable = ....,
                                    AnotherVariable = ....}
                       ).ToList();

      return TheQueryFromDB
                .Select(s => (
                     SomeVariable = s.SomeVariable, 
                     AnotherVariable = s.AnotherVariable))
                 .ToList();
  }
}

You might need to install System.ValueTuple nuget package though.

Directly from the docs:

$comma_separated = implode(",", $array);

A solution that works in WinForms:

var w = new Form() { Size = new Size(0, 0) };
Task.Delay(TimeSpan.FromSeconds(10))
    .ContinueWith((t) => w.Close(), TaskScheduler.FromCurrentSynchronizationContext());

MessageBox.Show(w, message, caption);

Based on the effect that closing the form that owns the message box will close the box as well.

Windows Forms controls have a requirement that they must be accessed on the same thread that created them. Using TaskScheduler.FromCurrentSynchronizationContext() will ensure that, assuming that the example code above is executed on the UI thread, or an user-created thread. The example will not work correctly if the code is executed on a thread from a thread pool (e.g. a timer callback) or a task pool (e.g. on a task created with TaskFactory.StartNew or Task.Run with default parameters).

Something like this should do the trick:

$(document).ready(function() {
    $('#toptitle').text(function(i, oldText) {
        return oldText === 'Profil' ? 'New word' : oldText;
    });
});

This only replaces the content when it is Profil. See text in the jQuery API.

It can be resolved as follows:

Go to Project properties.

Then 'Java Compiler' -> Check the box ('Enable project specific settings')

Change the compiler compliance level to '5.0' & click ok

Select the checkbox for "Use default compliance settings"

Canvas text support is actually pretty good - you can control font, size, color, horizontal alignment, vertical alignment, and you can also get text metrics to get the text width in pixels. In addition, you can also use canvas transforms to rotate, stretch and even invert text.

There is still hope to solve this using pure (GNU) sed. Despite this is not a generic solution in some cases you can use "loops" to eliminate all the unnecessary parts of the string like this:

sed -r -e ":loop" -e 's|(http://.+)/.*|\1|' -e "t loop"

• -r: Use extended regex (for + and unescaped parenthesis)
• ":loop": Define a new label named "loop"
• -e: add commands to sed
• "t loop": Jump back to label "loop" if there was a successful substitution

The only problem here is it will also cut the last separator character ('/'), but if you really need it you can still simply put it back after the "loop" finished, just append this additional command at the end of the previous command line:

-e "s,$,/,"

Now dstat provides the feature to find out in your running system which process is candidate for getting killed by oom mechanism

dstat --top-oom
 --out-of-memory---
  kill score
 java           77
 java           77
 java           77

and as per man page

  --top-oom
          show process that will be killed by OOM the first

Sven Marnach excellent solution is directly translatable into ElementTree which is part of recent Python distributions:

from xml.etree import ElementTree as ET

s = """<table>
  <tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
  <tr><td>a</td><td>b</td><td>c</td></tr>
  <tr><td>d</td><td>e</td><td>f</td></tr>
  <tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""

table = ET.XML(s)
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
    values = [col.text for col in row]
    print(dict(zip(headers, values)))

same output as Sven Marnach's answer...

A revert commit is just like any other commit in git. Meaning, you can revert it, as in:

git revert 648d7d808bc1bca6dbf72d93bf3da7c65a9bd746

That obviously only makes sense once the changes were pushed, and especially when you can't force push onto the destination branch (which is a good idea for your master branch). If the change has not been pushed, just do cherry-pick, revert or simply remove the revert commit as per other posts.

In our team, we have a rule to use a revert on Revert commits that were committed in the main branch, primarily to keep the history clean, so that you can see which commit reverts what:

      7963f4b2a9d   Revert "Revert "OD-9033 parallel reporting configuration"
      "This reverts commit a0e5e86d3b66cf206ae98a9c989f649eeba7965f.
                    ...
     a0e5e86d3b6    Revert "OD-9055 paralel reporting configuration"
     This reverts commit 648d7d808bc1bca6dbf72d93bf3da7c65a9bd746.
                ...
     Merge pull request parallel_reporting_dbs to master* commit 
    '648d7d808bc1bca6dbf72d93bf3da7c65a9bd746'

This way, you can trace the history and figure out the whole story, and even those without the knowledge of the legacy could work it out for themselves. Whereas, if you cherry-pick or rebase stuff, this valuable information is lost (unless you include it in the comment).

Obviously, if a commit reverted and re-reverted more than once that becomes quite messy.

The problem here is the performance, if you have a lot of rows it will be a problem.

If it is your case, please try with this:

import pandas as pd

source = pd.DataFrame({'Country' : ['USA', 'USA', 'Russia','USA'], 
              'City' : ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
              'Short_name' : ['NY','New','Spb','NY']})

source.groupby(['Country','City']).agg(lambda x:x.value_counts().index[0])

source.groupby(['Country','City']).Short_name.value_counts().groupby['Country','City']).first()

Your syntax is fine, it will return rows where LastAdDate lies within the last 6 months;

select cast('01-jan-1970' as datetime) as LastAdDate into #PubAdvTransData 
    union select GETDATE()
    union select NULL
    union select '01-feb-2010'

DECLARE @sp_Date DATETIME = DateAdd(m, -6, GETDATE())

SELECT * FROM #PubAdvTransData pat
     WHERE (pat.LastAdDate > @sp_Date)

>2010-02-01 00:00:00.000
>2010-04-29 21:12:29.920

Are you sure LastAdDate is of type DATETIME?

The MySQL daemon should not be executed as the system user root which (normally) do not has any restrictions.

According to your cli, I suppose you wanted to execute the initscript instead:

sudo /etc/init.d/mysql stop

Another way would be to use the mysqladmin tool (note, root is the MySQL root user here, not the system root user):

/usr/local/mysql/bin/mysqladmin --port=8889 -u root shutdown

Partials can be used to make new derived functions that have some input parameters pre-assigned

To see some real world usage of partials, refer to this really good blog post:
http://chriskiehl.com/article/Cleaner-coding-through-partially-applied-functions/

A simple but neat beginner's example from the blog, covers how one might use partial on re.search to make code more readable. re.search method's signature is:

search(pattern, string, flags=0) 

By applying partial we can create multiple versions of the regular expression search to suit our requirements, so for example:

is_spaced_apart = partial(re.search, '[a-zA-Z]\s\=')
is_grouped_together = partial(re.search, '[a-zA-Z]\=')

Now is_spaced_apart and is_grouped_together are two new functions derived from re.search that have the pattern argument applied(since pattern is the first argument in the re.search method's signature).

The signature of these two new functions(callable) is:

is_spaced_apart(string, flags=0)     # pattern '[a-zA-Z]\s\=' applied
is_grouped_together(string, flags=0) # pattern '[a-zA-Z]\=' applied

This is how you could then use these partial functions on some text:

for text in lines:
    if is_grouped_together(text):
        some_action(text)
    elif is_spaced_apart(text):
        some_other_action(text)
    else:
        some_default_action()

You can refer the link above to get a more in depth understanding of the subject, as it covers this specific example and much more..

Perhaps use information_schema:

SELECT EXISTS(
    SELECT * 
    FROM information_schema.tables 
    WHERE 
      table_schema = 'company3' AND 
      table_name = 'tableincompany3schema'
);

Try:

$(document).ready(function() {
    $('#contact-form').validate({submitHandler: function(form) {
         var data = $('#contact-form').serialize();   
         $.post(
              'url_request',
               {data: data},
               function(response){
                  console.log(response);
               }
          );
         }
    });
});

Notepad++ v6.6.3 with plugin "XML Tools" and shortcut Ctrl + Alt + Shift + B works fine.

To only strip whitespaces (in my case spaces and tabs) from lines with at least one non-whitespace character (this way empty indented lines are not touched):

sed -i -r 's/([^ \t]+)[ \t]+$/\1/' "$file"

If you just want to iterate over these sets of elements rather than construct a separate data structure, consider using iterators to construct a generator expression:

def shift(l,n):
    return itertools.islice(itertools.cycle(l),n,n+len(l))

>>> list(shift([1,2,3],1))
[2, 3, 1]

I could be wrong, but I believe since you are inheriting from foo, you have to call a base constructor. Since you explicitly defined the foo constructor to require (int, int) now you need to pass that up the chain.

public bar(int a, int b) : base(a, b)
{
     c = a * b;
}

This will initialize foo's variables first and then you can use them in bar. Also, to avoid confusion I would recommend not naming parameters the exact same as the instance variables. Try p_a or something instead, so you won't accidentally be handling the wrong variable.

Use this:

<a href="<?php echo(($_SERVER['HTTPS'] ? 'https://' : 'http://').$_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]); ?>">Whatever</a>

It will create a HREF using the current URL...

I only put this in for completeness. I've learned plenty from marius and mdml. Here are the edge weights. Sorry about the arrows. Looks like I'm not the only one saying it can't be helped. I couldn't render this with ipython notebook I had to go straight from python which was the problem with getting my edge weights in sooner.

Actually, you need to update your repo first, then an upgrade of your Glibc can fix this issue.

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

If you are planning to hide show some span based on click event which is initially hidden with style="display:none" then .toggle() is best option to go with.

$("span").toggle();

Reasons : Each time you don't need to check whether the style is already there or not. .toggle() will take care of that automatically and hide/show span based on current state.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="button" value="Toggle" onclick="$('#hiddenSpan').toggle();"/>_x000D_
<br/>_x000D_
<br/>_x000D_
<span id="hiddenSpan" style="display:none">Just toggle me</span>

Each ng-repeat creates a child scope with the passed data, and also adds an additional $index variable in that scope.

So what you need to do is reach up to the parent scope, and use that $index.

See http://plnkr.co/edit/FvVhirpoOF8TYnIVygE6?p=preview

<li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu($parent.$index)" ng-repeat="tutorial in section.tutorials">

body {
  position:relative; // that's it
  overflow:hidden;
}

Hope this could help Too

$('#selectBox option[value="3"]').attr('selected', true);

If you want to iterate over all the values:

dict.values.forEach { value in
    // print(value)
}

You don't mention what language you want to track these in, but I found two for javascript:

http://www.cambiaresearch.com/c4/702b8cd1-e5b0-42e6-83ac-25f0306e3e25/Javascript-Char-Codes-Key-Codes.aspx

None of the rest of the answers use:

com.google.android.gms.location.FusedLocationProviderClient

Which is the Fused Location Provider and the main entry point for interacting with the fused location provider by Google, and it is very hard to find a good example. This was released mid 2017 by Google.

Google Play services location APIs are preferred over the Android framework location APIs (android.location)

If you are currently using the Android framework location APIs, you are strongly encouraged to switch to the Google Play services location APIs as soon as possible.

For you to use the Google Location API, first add this to your build.gradle

compile 'com.google.android.gms:play-services:11.0.0'

Then you can use this class Wherebouts.java:

import android.location.Location;
import android.os.Looper;
import android.util.Log;

import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.location.LocationCallback;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationResult;
import com.google.android.gms.location.LocationServices;
import com.google.android.gms.location.LocationSettingsRequest;

/**
 * Uses Google Play API for obtaining device locations
 * Created by alejandro.tkachuk 
 * [email protected]
 * www.calculistik.com Mobile Development
 */

public class Wherebouts {

    private static final Wherebouts instance = new Wherebouts();

    private static final String TAG = Wherebouts.class.getSimpleName();

    private FusedLocationProviderClient mFusedLocationClient;
    private LocationCallback locationCallback;
    private LocationRequest locationRequest;
    private LocationSettingsRequest locationSettingsRequest;

    private Workable<GPSPoint> workable;

    private static final long UPDATE_INTERVAL_IN_MILLISECONDS = 1000;
    private static final long FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS = 1000;

    private Wherebouts() {
        this.locationRequest = new LocationRequest();
        this.locationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
        this.locationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
        this.locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
        builder.addLocationRequest(this.locationRequest);
        this.locationSettingsRequest = builder.build();

        this.locationCallback = new LocationCallback() {
            @Override
            public void onLocationResult(LocationResult locationResult) {
                super.onLocationResult(locationResult); // why? this. is. retarded. Android.
                Location currentLocation = locationResult.getLastLocation();

                GPSPoint gpsPoint = new GPSPoint(currentLocation.getLatitude(), currentLocation.getLongitude());
                Log.i(TAG, "Location Callback results: " + gpsPoint);
                if (null != workable)
                    workable.work(gpsPoint);
            }
        };

        this.mFusedLocationClient = LocationServices.getFusedLocationProviderClient(MainApplication.getAppContext());
        this.mFusedLocationClient.requestLocationUpdates(this.locationRequest,
                this.locationCallback, Looper.myLooper());
    }

    public static Wherebouts instance() {
        return instance;
    }

    public void onChange(Workable<GPSPoint> workable) {
        this.workable = workable;
    }

    public LocationSettingsRequest getLocationSettingsRequest() {
        return this.locationSettingsRequest;
    }

    public void stop() {
        Log.i(TAG, "stop() Stopping location tracking");
        this.mFusedLocationClient.removeLocationUpdates(this.locationCallback);
    }

}

From your Activity, you can use it like this, by passing a Workable object. A Workable object is nothing more than a custom Callback alike object.

 Wherebouts.instance().onChange(workable);

By using a callback like Workable, you will write UI related code in your Activity and leave the hustle of working with GPS to a helper class, like Wherebouts.

    new Workable<GPSPoint>() {
        @Override
        public void work(GPSPoint gpsPoint) {
            // draw something in the UI with this new data
        }
    };

Of course you would need to ask for the corresponding permissions to the Android OS for your App to use. You can read the following documentation for more info about that or do some research.

• Android Reference https://developer.android.com/training/location/index.html
• Wherebouts https://www.calculistik.com/Wherebouts.java
• GPSPoint https://www.calculistik.com/GPSPoint.java
• Workable https://www.calculistik.com/Workable.java

Here's a reworking of your sample to get you started.

• your sample has a static event - it's more usual for an event to come from a class instance, but I've left it static below.

• the sample below also uses the more standard naming OnXxx for the method that raises the event.

• the sample below does not consider thread-safety, which may well be more of an issue if you insist on your event being static.

.

public enum MyEvents{ 
     Event1 
} 

public class MyEventArgs : EventArgs
{
    public MyEventArgs(MyEvents myEvents)
    {
        MyEvents = myEvents;
    }

    public MyEvents MyEvents { get; private set; }
}

public static class MyClass
{
     public static event EventHandler<MyEventArgs> EventTriggered; 

     public static void Trigger(MyEvents myEvents) 
     {
         OnMyEvent(new MyEventArgs(myEvents));
     }

     protected static void OnMyEvent(MyEventArgs e)
     {
         if (EventTriggered != null)
         {
             // Normally the first argument (sender) is "this" - but your example
             // uses a static event, so I'm passing null instead.
             // EventTriggered(this, e);
             EventTriggered(null, e);
         } 
     }
}

I suspect your string already actually only contains a single backslash, but you're looking at it in the debugger which is escaping it for you into a form which would be valid as a regular string literal in C#.

If print it out in the console, or in a message box, does it show with two backslashes or one?

If you actually want to replace a double backslash with a single one, it's easy to do so:

text = text.Replace(@"\\", @"\");

... but my guess is that the original doesn't contain a double backslash anyway. If this doesn't help, please give more details.

EDIT: In response to the edited question, your stringToBeReplaced only has a single backslash in. Really. Wherever you're seeing two backslashes, that viewer is escaping it. The string itself doesn't have two backslashes. Examine stringToBeReplaced.Length and count the characters.

As an alternative, you can make use of X-Forwarded-Proto header to force a redirect to HTTPS.

add these lines in the .htaccess file

### Force HTTPS
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

this is only because the constructor of HashMap requires an arg of Map generic type and Properties implements Map.

This will work, though with a warning

    Properties properties = new Properties();
    Map<String, String> map = new HashMap(properties);

Although adequate answers have already been given, I'd like to propose a less verbose solution, that can be used without the helper methods available in an MVC controller class. Using a third party library called "RazorEngine" you can use .Net file IO to get the contents of the razor file and call

string html = Razor.Parse(razorViewContentString, modelObject);

Get the third party library here.

I was getting this error, only in Chrome (last version 24.0.1312.57 m), and only if the image was larger than the html img. I was using a php script to output the image like this:

header('Content-Length: '.strlen($data));
header("Content-type: image/{$ext}");
echo base64_decode($data);

I resolved it adding 1 to the lenght of the image:

header('Content-Length: '.strlen($data) + 1);
header("Content-type: image/{$ext}");
echo base64_decode($data);

Appears that Chrome dont expect the correct number of bytes.

Tested with sucess in Chrome and IE 9. Hope this help.

I found this nice video on the Clojure subreddit about FRP. It is pretty easy to understand even if you don't know Clojure.

Here's the video: http://www.youtube.com/watch?v=nket0K1RXU4

Here's the source the video refers to in the 2nd half: https://github.com/Cicayda/yolk-examples/blob/master/src/yolk_examples/client/autocomplete.cljs

I have written the following method using this case.

First, add the namespace: System.Reflection

For Example: T is return type(ClassName) and dr is parameter to mapping DataReader

C#, Call mapping method like the following:

List<Person> personList = new List<Person>();
personList = DataReaderMapToList<Person>(dataReaderForPerson);

This is the mapping method:

public static List<T> DataReaderMapToList<T>(IDataReader dr)
{
    List<T> list = new List<T>();
    T obj = default(T);
    while (dr.Read()) {
        obj = Activator.CreateInstance<T>();
        foreach (PropertyInfo prop in obj.GetType().GetProperties()) {
            if (!object.Equals(dr[prop.Name], DBNull.Value)) {
                prop.SetValue(obj, dr[prop.Name], null);
            }
        }
        list.Add(obj);
    }
    return list;
}

VB.NET, Call mapping method like the following:

Dim personList As New List(Of Person)
personList = DataReaderMapToList(Of Person)(dataReaderForPerson)

This is the mapping method:

Public Shared Function DataReaderMapToList(Of T)(ByVal dr As IDataReader) As List(Of T)
        Dim list As New List(Of T)
        Dim obj As T
        While dr.Read()
            obj = Activator.CreateInstance(Of T)()
            For Each prop As PropertyInfo In obj.GetType().GetProperties()
                If Not Object.Equals(dr(prop.Name), DBNull.Value) Then
                    prop.SetValue(obj, dr(prop.Name), Nothing)
                End If
            Next
            list.Add(obj)
        End While
        Return list
    End Function

a += b is essentially the same as a = a + b, except that:

• + always returns a newly allocated object, but += should (but doesn't have to) modify the object in-place if it's mutable (e.g. list or dict, but int and str are immutable).

• In a = a + b, a is evaluated twice.

• Python: Simple Statements

  • A simple statement is comprised within a single logical line.

If this is the first time you encounter the += operator, you may wonder why it matters that it may modify the object in-place instead of building a new one. Here is an example:

# two variables referring to the same list
>>> list1 = []
>>> list2 = list1

# += modifies the object pointed to by list1 and list2
>>> list1 += [0]
>>> list1, list2
([0], [0])

# + creates a new, independent object
>>> list1 = []
>>> list2 = list1
>>> list1 = list1 + [0]
>>> list1, list2
([0], [])

Take a look at ?legend and try this:

legend('topright', names(a)[-1] , 
   lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)

The code compiles ok for me. May be you have forgotten to add the import:

import android.app.AlertDialog;

Anyway, you have a good tutorial here.

I only just noticed this question, and wanted to add my $.02 to this.

In case of Java, this is not actually an option. The "unreachable code" error doesn't come from the fact that JVM developers thought to protect developers from anything, or be extra vigilant, but from the requirements of the JVM specification.

Both Java compiler, and JVM, use what is called "stack maps" - a definite information about all of the items on the stack, as allocated for the current method. The type of each and every slot of the stack must be known, so that a JVM instruction doesn't mistreat item of one type for another type. This is mostly important for preventing having a numeric value ever being used as a pointer. It's possible, using Java assembly, to try to push/store a number, but then pop/load an object reference. However, JVM will reject this code during class validation,- that is when stack maps are being created and tested for consistency.

To verify the stack maps, the VM has to walk through all the code paths that exist in a method, and make sure that no matter which code path will ever be executed, the stack data for every instruction agrees with what any previous code has pushed/stored in the stack. So, in simple case of:

Object a;
if (something) { a = new Object(); } else { a = new String(); }
System.out.println(a);

at line 3, JVM will check that both branches of 'if' have only stored into a (which is just local var#0) something that is compatible with Object (since that's how code from line 3 and on will treat local var#0).

When compiler gets to an unreachable code, it doesn't quite know what state the stack might be at that point, so it can't verify its state. It can't quite compile the code anymore at that point, as it can't keep track of local variables either, so instead of leaving this ambiguity in the class file, it produces a fatal error.

Of course a simple condition like if (1<2) will fool it, but it's not really fooling - it's giving it a potential branch that can lead to the code, and at least both the compiler and the VM can determine, how the stack items can be used from there on.

P.S. I don't know what .NET does in this case, but I believe it will fail compilation as well. This normally will not be a problem for any machine code compilers (C, C++, Obj-C, etc.)

Here is my solution - code is inspired by Tracy Debugger. It was changed for support different server ports. You can get full current URL including $_SERVER['REQUEST_URI'] or just the basic server URL. Check my function:

function getCurrentUrl($full = true) {
    if (isset($_SERVER['REQUEST_URI'])) {
        $parse = parse_url(
            (isset($_SERVER['HTTPS']) && strcasecmp($_SERVER['HTTPS'], 'off') ? 'https://' : 'http://') .
            (isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : (isset($_SERVER['SERVER_NAME']) ? $_SERVER['SERVER_NAME'] : '')) . (($full) ? $_SERVER['REQUEST_URI'] : null)
        );
        $parse['port'] = $_SERVER["SERVER_PORT"]; // Setup protocol for sure (80 is default)
        return http_build_url('', $parse);
    }
}

Here is test code:

// Follow $_SERVER variables was set only for test
$_SERVER['HTTPS'] = 'off'; // on
$_SERVER['SERVER_PORT'] = '9999'; // Setup
$_SERVER['HTTP_HOST'] = 'some.crazy.server.5.name:8088'; // Port is optional there
$_SERVER['REQUEST_URI'] = '/150/tail/single/normal?get=param';

echo getCurrentUrl();
// http://some.crazy.server.5.name:9999/150/tail/single/normal?get=param

echo getCurrentUrl(false);
// http://some.crazy.server.5.name:9999/

Can also do it by regex:

Pattern queryLangPattern = Pattern.compile("true|false", Pattern.CASE_INSENSITIVE);
Matcher matcher = queryLangPattern.matcher(booleanParam);
return matcher.matches();

First make sure to have the right data types:

df["Date"] = pd.to_datetime(df["Date"])
df["Time"] = pd.to_timedelta(df["Time"])

Then you easily combine them:

df["DateTime"] = df["Date"] + df["Time"]

Although all the answers given are correct, in fact they do not completely answer the question which was about using the [] construct and more generally filling the array with objects.

A more relevant answer can be found in how to build arrays of objects in PHP without specifying an index number? which clearly shows how to solve the problem.

I would use BigDecimal for the solution. Like this:

    double value = 3.25;
    BigDecimal wholeValue = BigDecimal.valueOf(value).setScale(0, BigDecimal.ROUND_DOWN);
    double fractionalValue = value - wholeValue.doubleValue();

solution to wait for several subprocesses and to exit when any one of them exits with non-zero status code is by using 'wait -n'

#!/bin/bash
wait_for_pids()
{
    for (( i = 1; i <= $#; i++ )) do
        wait -n $@
        status=$?
        echo "received status: "$status
        if [ $status -ne 0 ] && [ $status -ne 127 ]; then
            exit 1
        fi
    done
}

sleep_for_10()
{
    sleep 10
    exit 10
}

sleep_for_20()
{
    sleep 20
}

sleep_for_10 &
pid1=$!

sleep_for_20 &
pid2=$!

wait_for_pids $pid2 $pid1

status code '127' is for non-existing process which means the child might have exited.

I've created a video tutorial for this. Just check:

Connect to Amazon EC2 file directory using FileZilla and SFTP, Video Tutorial

Summary of above video tutorial:

1. Edit (Preferences) > Settings > Connection > SFTP, Click "Add key file”
2. Browse to the location of your .pem file and select it.
3. A message box will appear asking your permission to convert the file into ppk format. Click Yes, then give the file a name and store it somewhere.
4. If the new file is shown in the list of Keyfiles, then continue to the next step. If not, then click "Add keyfile..." and select the converted file.

5. File > Site Manager Add a new site with the following parameters:

   Host: Your public DNS name of your EC2 instance, or the public IP address of the server.

   Protocol: SFTP

   Logon Type: Normal

   User: From the docs: "For Amazon Linux, the default user name is ec2-user. For RHEL5, the user name is often root but might be ec2-user. For Ubuntu, the user name is ubuntu. For SUSE Linux, the user name is root. For Debian, the user name is admin. Otherwise, check with your AMI provider."

   Press Connect Button - If saving of passwords has been disabled, you will be prompted that the logon type will be changed to 'Ask for password'. Say 'OK' and when connecting, at the password prompt push 'OK' without entering a password to proceed past the dialog.

   Note: FileZilla automatically figures out which key to use. You do not need to specify the key after importing it as described above.

If you use Cyberduck follow this.

Check this post if you have any permission issues.

This issue has been recently fixed (Nov 2010) by Google, see https://code.google.com/p/analytics-issues/issues/detail?id=671. But be aware that as a good fix it brings more bugs :)

You will also have to follow the initialisation method listed here: https://developers.google.com/analytics/devguides/collection/ios/v2.

The latest instructions are going to give you a headache because it references utilities not included in the pod. Below will fail with the cocoapod

NSAssert(!configureError, @"Error configuring Google services: %@", configureError);

Here's a bit more information specifically regarding the PATH variable in Lion OS 10.7.x:

If you need to set the PATH globally, the PATH is built by the system in the following order:

1. Parsing the contents of the file /private/etc/paths, one path per line
2. Parsing the contents of the folder /private/etc/paths.d. Each file in that folder can contain multiple paths, one path per line. Load order is determined by the file name first, and then the order of the lines in the file.
3. A setenv PATH statement in /private/etc/launchd.conf, which will append that path to the path already built in #1 and #2 (you must not use $PATH to reference the PATH variable that has been built so far). But, setting the PATH here is completely unnecessary given the other two options, although this is the place where other global environment variables can be set for all users.

These paths and variables are inherited by all users and applications, so they are truly global -- logging out and in will not reset these paths -- they're built for the system and are created before any user is given the opportunity to login, so changes to these require a system restart to take effect.

BTW, a clean install of OS 10.7.x Lion doesn't have an environment.plist that I can find, so it may work but may also be deprecated.

RANK() is good, but it assigns the same rank for equal or similar values. And if you need unique rank, then ROW_NUMBER() solves this problem

ROW_NUMBER() OVER (ORDER BY totals DESC) AS xRank

In order to generate a checksum, you'll need to load each byte of the file, and perform processing on it. You'll then have to do this on the second file. The processing will almost definitely be slower than the comparison check.

As for generating a checksum: You can do this easily with the cryptography classes. Here's a short example of generating an MD5 checksum with C#.

However, a checksum may be faster and make more sense if you can pre-compute the checksum of the "test" or "base" case. If you have an existing file, and you're checking to see if a new file is the same as the existing one, pre-computing the checksum on your "existing" file would mean only needing to do the DiskIO one time, on the new file. This would likely be faster than a byte-by-byte comparison.

Here's a transcription of another answer I gave to a similar question:

If you apply utf8_encode() to an already UTF8 string it will return a garbled UTF8 output.

I made a function that addresses all this issues. It´s called Encoding::toUTF8().

You dont need to know what the encoding of your strings is. It can be Latin1 (iso 8859-1), Windows-1252 or UTF8, or the string can have a mix of them. Encoding::toUTF8() will convert everything to UTF8.

I did it because a service was giving me a feed of data all messed up, mixing UTF8 and Latin1 in the same string.

Usage:

$utf8_string = Encoding::toUTF8($utf8_or_latin1_or_mixed_string);

$latin1_string = Encoding::toLatin1($utf8_or_latin1_or_mixed_string);

Download:

https://github.com/neitanod/forceutf8

Update:

I've included another function, Encoding::fixUFT8(), wich will fix every UTF8 string that looks garbled.

Usage:

$utf8_string = Encoding::fixUTF8($garbled_utf8_string);

Examples:

echo Encoding::fixUTF8("Fédération Camerounaise de Football");
echo Encoding::fixUTF8("Fédération Camerounaise de Football");
echo Encoding::fixUTF8("FÃÂédÃÂération Camerounaise de Football");
echo Encoding::fixUTF8("Fédération Camerounaise de Football");

will output:

Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football

Update: I've transformed the function (forceUTF8) into a family of static functions on a class called Encoding. The new function is Encoding::toUTF8().

In html use

<input :required="condition" />

And define in data property like

data () {
   return {
      condition: false
   }
}

This is based on @Reid's solution. Except:

• I'm not changing the Array prototype.
• Moving an item out of bounds to the right does not create undefined items, it just moves the item to the right-most position.

Function:

function move(array, oldIndex, newIndex) {
    if (newIndex >= array.length) {
        newIndex = array.length - 1;
    }
    array.splice(newIndex, 0, array.splice(oldIndex, 1)[0]);
    return array;
}

Unit tests:

describe('ArrayHelper', function () {
    it('Move right', function () {
        let array = [1, 2, 3];
        arrayHelper.move(array, 0, 1);
        assert.equal(array[0], 2);
        assert.equal(array[1], 1);
        assert.equal(array[2], 3);
    })
    it('Move left', function () {
        let array = [1, 2, 3];
        arrayHelper.move(array, 1, 0);
        assert.equal(array[0], 2);
        assert.equal(array[1], 1);
        assert.equal(array[2], 3);
    });
    it('Move out of bounds to the left', function () {
        let array = [1, 2, 3];
        arrayHelper.move(array, 1, -2);
        assert.equal(array[0], 2);
        assert.equal(array[1], 1);
        assert.equal(array[2], 3);
    });
    it('Move out of bounds to the right', function () {
        let array = [1, 2, 3];
        arrayHelper.move(array, 1, 4);
        assert.equal(array[0], 1);
        assert.equal(array[1], 3);
        assert.equal(array[2], 2);
    });
});

This is all that is needed:

<activity android:windowSoftInputMode="adjustResize"> </activity>

The simplest is to call stop propagation on an event handler. $event works the same in Angular 2, and contains the ongoing event (by it a mouse click, mouse event, etc.):

(click)="onEvent($event)"

on the event handler, we can there stop the propagation:

onEvent(event) {
   event.stopPropagation();
}

$http_name_of_the_header_key

i.e if you have origin = domain.com in header, you can use $http_origin to get "domain.com"

In nginx does support arbitrary request header field. In the above example last part of a variable name is the field name converted to lower case with dashes replaced by underscores

Reference doc here: http://nginx.org/en/docs/http/ngx_http_core_module.html#var_http_

For your example the variable would be $http_my_custom_header.

FOR /r %%X IN (*) DO (ECHO %%X & DEL %%X)

The first answer is too complex, historic, and uninformative for my tastes.

It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,

• Free you from having to manually remove what you don't want, by forcing you to whitelist what you do want,
• Free resources that would otherwise be taken up because of Docker's implementation.

Let's start with the first. Very often with something like Debian you'll see.

RUN apt-get update \ 
  && apt-get dist-upgrade \
  && apt-get install <whatever> \
  && apt-get clean

We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,

RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;

It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree for an example of that).

By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean), and you would otherwise have lots of un-needed files in your final image.

One thing I discovered is that using the \include command will often insert and extra blank page. Riffing on the previous trick with the \let command, I inserted \let\include\input near the beginning of the document, and that got rid of most of the excessive blank pages.

Try this:

private string GetJArrayValue(JObject yourJArray, string key)
{
    foreach (KeyValuePair<string, JToken> keyValuePair in yourJArray)
    {
        if (key == keyValuePair.Key)
        {
            return keyValuePair.Value.ToString();
        }
    }
}

More succinct-: sum(is.na(x[1]))

That is

1. x[1] Look at the first column

2. is.na() true if it's NA

3. sum() TRUE is 1, FALSE is 0

You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.

You should use this request:

curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod

Starting from Framework v4.5 you can use Activator.CreateInstanceFrom() to easily instantiate classes within assemblies. The following example shows how to use it and how to call a method passing parameters and getting return value.

    // Assuming moduleFileName contains full or valid relative path to assembly    
    var moduleInstance = Activator.CreateInstanceFrom(moduleFileName, "MyNamespace.MyClass");
    MethodInfo mi = moduleInstance.Unwrap().GetType().GetMethod("MyMethod");
    // Assuming the method returns a boolean and accepts a single string parameter
    bool rc = Convert.ToBoolean(mi.Invoke(moduleInstance.Unwrap(), new object[] { "MyParamValue" } ));

var a_href = $('div.cpt').find('h2 a').attr('href');

should be

var a_href = $(this).find('div.cpt').find('h2 a').attr('href');

In the first line, your query searches the entire document. In the second, the query starts from your tr element and only gets the element underneath it. (You can combine the finds if you like, I left them separate to illustrate the point.)

You want either auto-fit or auto-fill inside the repeat() function:

grid-template-columns: repeat(auto-fit, 186px);

The difference between the two becomes apparent if you also use a minmax() to allow for flexible column sizes:

grid-template-columns: repeat(auto-fill, minmax(186px, 1fr));

This allows your columns to flex in size, ranging from 186 pixels to equal-width columns stretching across the full width of the container. auto-fill will create as many columns as will fit in the width. If, say, five columns fit, even though you have only four grid items, there will be a fifth empty column:

Using auto-fit instead will prevent empty columns, stretching yours further if necessary:

I think that besides some syntax limitations; the naming conventions reasoning are very much language independent. I mean, the arguments in favor of c_style_functions and JavaLikeCamelCase could equally well be used the opposite way, it's just that language users tend to follow the language authors.

having said that, i think most libraries tend to roughly follow a simplification of Java's CamelCase. I find Douglas Crockford advices tasteful enough for me.

For example you have a start program named run.sh to start it working at background do the following command line. ./run.sh &>/dev/null &

In C, using a previously undeclared function constitutes an implicit declaration of the function. In an implicit declaration, the return type is int if I recall correctly. Now, GCC has built-in definitions for some standard functions. If an implicit declaration does not match the built-in definition, you get this warning.

To fix the problem, you have to declare the functions before using them; normally you do this by including the appropriate header. I recommend not to use the -fno-builtin-* flags if possible.

Instead of stdlib.h, you should try:

#include <string.h>

That's where strcpy and strncpy are defined, at least according to the strcpy(2) man page.

The exit function is defined in stdlib.h, though, so I don't know what's going on there.

Another reason for "lost update" can be the next:

• If the static getDerivedStateFromProps is defined then it is rerun in every update process according to official documentation https://reactjs.org/docs/react-component.html#updating.
• so if that state value comes from props at the beginning it is overwrite in every update.

If it is the problem then U can avoid setting the state during update, you should check the state parameter value like this

static getDerivedStateFromProps(props: TimeCorrectionProps, state: TimeCorrectionState): TimeCorrectionState {
   return state ? state : {disable: false, timeCorrection: props.timeCorrection};
}

Another solution is add a initialized property to state, and set it up in the first time (if the state is initialized to non null value.)

Here's a bash script to check the maximum limit of a remote server (uses curl and perl).

You just need some kind of an url that can be extended with 'x' and always return 200 (or adapt it to your needs). At some point it will break and the script will display the max length.

Here's the code:

url='http://someurl/someendpoint?var1=blah&token='
ok=0
times=1

while :; do
    length=$((times+${#url}))
    echo trying with $length
    token=$(perl -le 'print "x"x'$times)
    result=$(curl -sLw '%{http_code}' -o /dev/null "${url}${token}")

    if [[ $result == 200 ]]; then
        if [[ $ok == $times ]]; then
            echo "max length is $length"
            break
        fi
        ok=$times
        times=$((times+1024))
    else
        times=$(((times+ok)/2))
    fi
done

Here's a solution I used (it needs #include <time.h>):

int msec = 0, trigger = 10; /* 10ms */
clock_t before = clock();

do {
  /*
   * Do something to busy the CPU just here while you drink a coffee
   * Be sure this code will not take more than `trigger` ms
   */

  clock_t difference = clock() - before;
  msec = difference * 1000 / CLOCKS_PER_SEC;
  iterations++;
} while ( msec < trigger );

printf("Time taken %d seconds %d milliseconds (%d iterations)\n",
  msec/1000, msec%1000, iterations);

Uri.parse(STRING);

See doc:

String: an RFC 2396-compliant, encoded URI

Url must be canonicalized before using, like this:

Uri.parse(Uri.decode(STRING));

Got the same question from a friend. My suggestion which does not require !Important looks like this: I add a custom class "no-border" which can be added to the bootstrap table.

.table.no-border tr td, .table.no-border tr th {
  border-width: 0;
}

I am developing a project which using SSR and now I want to share my solution based on some answers here.

My goals is to preload an image to show it when internet connection offline. (It may be not the best practice, but since it works for me, that's ok for now) FYI, I also use ReactHooks in this project.

  useEffect(() => {
    // preload image for offline network
    const ErrorFailedImg = require('../../../../assets/images/error-review-failed.jpg');
    if (typeof window !== 'undefined') {
      new Image().src = ErrorFailedImg;
    }
  }, []);

To use the image, I write it like this

<img src="/assets/images/error-review-failed.jpg" />

Not sure I understand the question correctly.

From what I gather, you want to be able to assign a value to Domain if it is null and also what to check if $args2 is supplied and according to the value, execute a certain code?

I changed the code to reassemble the assumptions made above.

Function DoStuff($computername, $arg2, $domain)
{
    if($domain -ne $null)
    {
        $domain = "Domain1"
    }

    if($arg2 -eq $null)
    {
    }
    else
    {
    }
}

DoStuff -computername "Test" -arg2 "" -domain "Domain2"
DoStuff -computername "Test" -arg2 "Test"  -domain ""
DoStuff -computername "Test" -domain "Domain2"
DoStuff -computername "Test" -arg2 "Domain2"

Did that help?

You can use a Junit Rule to create this temporary folder for your test:

@Rule public TemporaryFolder temporaryFolder = new TemporaryFolder(); File file = temporaryFolder.newFile(".src/test/resources/abc.xml");

The calculated column trick is widely known as a "nullbuster"; my notes credit Steve Kass:

CREATE TABLE dupNulls (
pk int identity(1,1) primary key,
X  int NULL,
nullbuster as (case when X is null then pk else 0 end),
CONSTRAINT dupNulls_uqX UNIQUE (X,nullbuster)
)

For those of you who are building on a MacOS, and don't like leaving your password in clear text on your machine, you can use the keychain tool to store the credentials and then inject it into the build. Credits go to Viktor Eriksson. https://pilloxa.gitlab.io/posts/safer-passwords-in-gradle/

To much code, you can use it like this:

#include<array>
#include<functional>

int main()
{
    std::array<int, 10> vec = { 1,2,3,4,5,6,7,8,9 };

    std::sort(std::begin(vec), 
              std::end(vec), 
              [](int a, int b) {return a > b; });

    for (auto item : vec)
      std::cout << item << " ";

    return 0;
}

Replace "vec" with your class and that's it.

As mentioned in the comments, there cannot be a continuous scale on variable of the factor type. You could change the factor to numeric as follows, just after you define the meltDF variable.

meltDF$variable=as.numeric(levels(meltDF$variable))[meltDF$variable]

Then, execute the ggplot command

  ggplot(meltDF[meltDF$value == 1,]) + geom_point(aes(x = MW, y =   variable)) +
     scale_x_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200)) +
     scale_y_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200))

And you will have your chart.

Hope this helps

 let alertController = UIAlertController(title: "Select Photo", message: "Select atleast one photo", preferredStyle: .alert)
    let action1 = UIAlertAction(title: "From Photo", style: .default) { (action) in
        print("Default is pressed.....")
    }
    let action2 = UIAlertAction(title: "Cancel", style: .cancel) { (action) in
        print("Cancel is pressed......")
    }
    let action3 = UIAlertAction(title: "Click new", style: .default) { (action) in

    }
    alertController.addAction(action1)
    alertController.addAction(action2)
    alertController.addAction(action3)
    self.present(alertController, animated: true, completion: nil)

}

The best way to do this is to set display: inline;. Note, however, that in inline display, you lose access to some layout properties, such as manual height and vertical margins, but this doesn't appear to be a problem for your page.

To Get The Data From the App.config

Keeping in mind you have to:

1. Added to the References -> System.Configuration
2. and also added this using statement -> using System.Configuration;

Just Simply do this

string value1 = ConfigurationManager.AppSettings["Value1"];

Alternatively, you can achieve this in one line, if you don't want to add using System.Configuration; explicitly.

string value1 = System.Configuration.ConfigurationManager.AppSettings["Value1"]

I Had the same problem.

The solution for me is:

You must have the same version of: Microsoft.ReportViewer.ProcessingObjectModel registred in C:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.ProcessingObjectModel, like you have registraded in web.config in developer server:

In my case i was only registred the 13. version in my prodution server and i have the 12. version in developer server.

the solution is install the version 12. in the prodution server too

the version 12. :

https://download.microsoft.com/download/A/1/2/A129F694-233C-4C7C-860F-F73139CF2E01/ENU/x86/ReportViewer.msi

Then now i have the version 12. in the prodution and the report work fine.

*** Remember to reset your IIS after instalation

I solved this problem using a different approach. You simply need to serialize the objects before passing through the closure, and de-serialize afterwards. This approach just works, even if your classes aren't Serializable, because it uses Kryo behind the scenes. All you need is some curry. ;)

Here's an example of how I did it:

def genMapper(kryoWrapper: KryoSerializationWrapper[(Foo => Bar)])
               (foo: Foo) : Bar = {
    kryoWrapper.value.apply(foo)
}
val mapper = genMapper(KryoSerializationWrapper(new Blah(abc))) _
rdd.flatMap(mapper).collectAsMap()

object Blah(abc: ABC) extends (Foo => Bar) {
    def apply(foo: Foo) : Bar = { //This is the real function }
}

Feel free to make Blah as complicated as you want, class, companion object, nested classes, references to multiple 3rd party libs.

KryoSerializationWrapper refers to: https://github.com/amplab/shark/blob/master/src/main/scala/shark/execution/serialization/KryoSerializationWrapper.scala

If you are converting a varchar to int make sure you do not have decimal places.

For example, if you are converting a varchar field with value (12345.0) to an integer then you get this conversion error. In my case I had all my fields with .0 as ending so I used the following statement to globally fix the problem.

CONVERT(int, replace(FIELD_NAME,'.0',''))

On item 1.16 of phpMyAdmin they say:

1.16 I cannot upload big dump files (memory, HTTP or timeout problems).

Starting with version 2.7.0, the import engine has been re–written and these problems should not occur. If possible, upgrade your phpMyAdmin to the latest version to take advantage of the new import features.

The first things to check (or ask your host provider to check) are the values of upload_max_filesize, memory_limit and post_max_size in the php.ini configuration file. All of these three settings limit the maximum size of data that can be submitted and handled by PHP. One user also said that post_max_size and memory_limit need to be larger than upload_max_filesize. There exist several workarounds if your upload is too big or your hosting provider is unwilling to change the settings:

Look at the $cfg['UploadDir'] feature. This allows one to upload a file to the server via scp, ftp, or your favorite file transfer method. PhpMyAdmin is then able to import the files from the temporary directory. More information is available in the Configuration of this document.

Using a utility (such as BigDump) to split the files before uploading. We cannot support this or any third party applications, but are aware of users having success with it.

If you have shell (command line) access, use MySQL to import the files directly. You can do this by issuing the “source” command from within MySQL:

source filename.sql;

Environment returns user data directory. And getFilesDir returns application data directory.

Like this post suggests, this can be done in the following way:

int Foo(CancellationToken token)
{
    Thread t = Thread.CurrentThread;
    using (token.Register(t.Abort))
    {
        // compute-bound work here
    }
}

Although it works, it's not recommended to use such approach. If you can control the code that executes in task, you'd better go with proper handling of cancellation.

Use Form.Activate() or Form.Focus() methods.

Please remove all jar files of Http from 'libs' folder and add below dependencies in gradle file:

compile 'org.apache.httpcomponents:httpclient:4.5'
compile 'org.apache.httpcomponents:httpcore:4.4.3'

or

useLibrary 'org.apache.http.legacy'

If you want to downgrade php from 7.1.1 to 5.6 in xampp follow the steps(For Windows):-

1. Go to https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/5.6.36/
2. Download and extract the file xampp-win32-5.6.36-0-VC11.zip see the image [image 1][1]

3. Delete php folder and apache folder present in C:\xampp

4. Copy php folder and apache folder from extracted file and paste it to C:\xampp

5. Add " C: " before \xampp\ to php ini file present in php folder.

6. Start your apache and MySQL and check php version. It will show php 5.6.36

Using dynamic variable for search in array

 /* https://ideone.com/Pfb0Ou */

$array = array('kitchen', 'bedroom', 'living_room', 'dining_room');

/* variable search */
$search = 'living_room';

if (in_array($search, $array)) {
    echo "this array contains $search";
} else
    echo "this array NOT contains $search";

Datetime formatting is performed by the org.joda.time.format.DateTimeFormatter class. Three classes provide factory methods to create formatters, and this is one. The others are ISODateTimeFormat and DateTimeFormatterBuilder.

DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MMM-dd");
LocalDate lDate = new LocalDate().parse("2005-nov-12",format);

final org.joda.time.LocalDate class is an immutable datetime class representing a date without a time zone. LocalDate is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

Not sure if it was because I'm working against SQL 2000 or not but I had to do this to get it to work.

string sql = "DECLARE @ID int; " +
             "INSERT INTO [MyTable] ([Stuff]) VALUES (@Stuff); " +
             "SET @ID = SCOPE_IDENTITY(); " +
             "SELECT @ID";

var id = connection.Query<int>(sql, new { Stuff = mystuff}).Single();

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

If you are using dynamics in .NET 4.5 you don't need to worry about INotifyPropertyChanged.

dynamic obj = new ExpandoObject();
obj.Name = "John";

if Name is bound to some control it just works fine.

You can start Eclipse in clean mode from the command line:

eclipse -clean

There are many answers already that tell you how to make a proper copy, but none of them say why your original 'copy' failed.

Python doesn't store values in variables; it binds names to objects. Your original assignment took the object referred to by my_list and bound it to new_list as well. No matter which name you use there is still only one list, so changes made when referring to it as my_list will persist when referring to it as new_list. Each of the other answers to this question give you different ways of creating a new object to bind to new_list.

Each element of a list acts like a name, in that each element binds non-exclusively to an object. A shallow copy creates a new list whose elements bind to the same objects as before.

new_list = list(my_list)  # or my_list[:], but I prefer this syntax
# is simply a shorter way of:
new_list = [element for element in my_list]

To take your list copy one step further, copy each object that your list refers to, and bind those element copies to a new list.

import copy  
# each element must have __copy__ defined for this...
new_list = [copy.copy(element) for element in my_list]

This is not yet a deep copy, because each element of a list may refer to other objects, just like the list is bound to its elements. To recursively copy every element in the list, and then each other object referred to by each element, and so on: perform a deep copy.

import copy
# each element must have __deepcopy__ defined for this...
new_list = copy.deepcopy(my_list)

See the documentation for more information about corner cases in copying.

I tried several solutions, nothing seemed to work. Setting my system JDK to match Android Studio's solved the problem.

Ensure your system java

java -version

Is the same as Androids

Symfony 2.0:

$em = $this->getDoctrine()->resetEntityManager();

Symfony 2.1+:

$em = $this->getDoctrine()->resetManager();

I have written a sort of "idiots guide" to the Y-Combinator in both Clojure and Scheme in order to help myself come to grips with it. They are influenced by material in "The Little Schemer"

In Scheme: https://gist.github.com/z5h/238891

or Clojure: https://gist.github.com/z5h/5102747

Both tutorials are code interspersed with comments and should be cut & pastable into your favourite editor.

• \r = CR (Carriage Return) → Used as a new line character in Mac OS before X
• \n = LF (Line Feed) → Used as a new line character in Unix/Mac OS X
• \r\n = CR + LF → Used as a new line character in Windows

You can use TrimEnd. It's efficient as well and looks clean.

"Name,".TrimEnd(',');

Check All with uncheck/check controller if all items is/isnt checked

JS:

e = checkbox id t= checkbox (item) class n= checkbox check all class

function checkAll(e,t,n){jQuery("#"+e).click(function(e){if(this.checked){jQuery("."+t).each(function(){this.checked=true;jQuery("."+n).each(function(){this.checked=true})})}else{jQuery("."+t).each(function(){this.checked=false;jQuery("."+n).each(function(){this.checked=false})})}});jQuery("."+t).click(function(e){var r=jQuery("."+t).length;var i=0;var s=0;jQuery("."+t).each(function(){if(this.checked==true){i++}if(this.checked==false){s++}});if(r==i){jQuery("."+n).each(function(){this.checked=true})}if(i<r){jQuery("."+n).each(function(){this.checked=false})}})}

HTML:

Check ALL controle class : chkall_ctrl

<input type="checkbox"name="chkall" id="chkall_up" class="chkall_ctrl"/>
<br/>
1.<input type="checkbox" value="1" class="chkall" name="chk[]" id="chk1"/><br/>
2.<input type="checkbox" value="2" class="chkall" name="chk[]" id="chk2"/><br/>
3.<input type="checkbox" value="3" class="chkall" name="chk[]" id="chk3"/><br/>
<br/>
<input type="checkbox"name="chkall" id="chkall_down" class="chkall_ctrl"/>

<script>
jQuery(document).ready(function($)
{
  checkAll('chkall_up','chkall','chkall_ctrl');
  checkAll('chkall_down','chkall','chkall_ctrl');
});
 </script>

Found here what I was looking for. Helped me recall what I used 3-4 years back.

I wanted to reuse the same syntax to be able to create table with data resulting from the join of a table.

Came up with below query after a few attempts.

SELECT a.*
INTO   DetailsArchive
FROM   (SELECT d.*
        FROM   details AS d
               INNER JOIN
               port AS p
               ON p.importid = d.importid
        WHERE  p.status = 2) AS a;

You cannot. A basic numeric constant is considered an integer (or long if followed by a "L"), so you must explicitly downcast it to a byte to pass it as a parameter. As far as I know there is no shortcut.

This answer is for XAMPP on Ubuntu.

The manual for installation and download is on (site official)

http://www.apachefriends.org/it/xampp-linux.html

After to start XAMPP simply call this command:

sudo /opt/lampp/lampp start

You should now see something like this on your screen:

Starting XAMPP 1.8.1...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.

If you have this

Starting XAMPP for Linux 1.8.1...                                                             
XAMPP: Another web server daemon is already running.                                          
XAMPP: Another MySQL daemon is already running.                                               
XAMPP: Starting ProFTPD...                                                                    
XAMPP for Linux started

. The solution is

sudo /etc/init.d/apache2 stop
sudo /etc/init.d/mysql stop

And the restast with sudo //opt/lampp/lampp restart

You to fix most of the security weaknesses simply call the following command:

/opt/lampp/lampp security

After the change this file

sudo kate //opt/lampp/etc/extra/httpd-xampp.conf

Find and replace on

    #
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
    Order deny,allow

Did they add a runtime List<> and/or Map<> type class to typepad 1.0

No, providing a runtime is not the focus of the TypeScript team.

is there a solid library out there someone wrote that provides this functionality?

I wrote (really just ported over buckets to typescript): https://github.com/basarat/typescript-collections

Update

JavaScript / TypeScript now support this natively and you can enable them with lib.d.ts : https://basarat.gitbooks.io/typescript/docs/types/lib.d.ts.html along with a polyfill if you want

If you need to set the UICollectionView scrolling Direction Horizental and you need to set cell width and height static. Please set the collectionview estimate size Automatic into None .
