We can simply write the array data to the filesystem but this will raise one error in which ',' will be appended to the end of the file. To handle this below code can be used:

var fs = require('fs');

var file = fs.createWriteStream('hello.txt');
file.on('error', function(err) { Console.log(err) });
data.forEach(value => file.write(`${value}\r\n`));
file.end();

\r\n

is used for the new Line.

\n

won't help. Please refer this

These 2 commands have several subtle differences if the file in question is already in the repo and under version control (previously committed etc.):

• git reset HEAD <file> unstages the file in the current commit.
• git rm --cached <file> will unstage the file for future commits also. It's unstaged untill it gets added again with git add <file>.

And there's one more important difference:

• After running git rm --cached <file> and push your branch to the remote, anyone pulling your branch from the remote will get the file ACTUALLY deleted from their folder, even though in your local working set the file just becomes untracked (i.e. not physically deleted from the folder).

This last difference is important for projects which include a config file where each developer on the team has a different config (i.e. different base url, ip or port setting) so if you're using git rm --cached <file> anyone who pulls your branch will have to manually re-create the config, or you can send them yours and they can re-edit it back to their ip settings (etc.), because the delete only effects people pulling your branch from the remote.

With Linq

var newList = GlobalStrings.Append(localStrings)

Make sure that your sas.png is marked as Build Action: Content and Copy To Output Directory: Copy Always in its Visual Studio Properties...

I think the C# source code goes like this...

Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;

and XAML should be

<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0" 
       Name="image1" Stretch="Fill" VerticalAlignment="Top" 
       Source="../Bilder/sas.png"
       Width="350" />  

EDIT

Dynamically I think XAML would provide best way to load Images ...

<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
       x:Name="MyImage"/>

where image.DataContext is string path.

MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";

public class MyImageSourceConverter : IValueConverter
{
    public object Convert(object value_, Type targetType_, 
    object parameter_, System.Globalization.CultureInfo culture_)
    {
        return (new ImageSourceConverter()).ConvertFromString (value.ToString());
    }

    public object ConvertBack(object value, Type targetType, 
    object parameter, CultureInfo culture)
    {
          throw new NotImplementedException();
    }
}

Now as you set a different data context, Image would be automatically loaded at runtime.

The only library that I got to work for Chrome, Firefox and MS Edge was rasterizeHTML. It outputs better quality that HTML2Canvas and is still supported unlike HTML2Canvas.

Getting Element and Downloading as PNG

var node= document.getElementById("elementId");
var canvas = document.createElement("canvas");
canvas.height = node.offsetHeight;
canvas.width = node.offsetWidth;
var name = "test.png"

rasterizeHTML.drawHTML(node.outerHTML, canvas)
     .then(function (renderResult) {
            if (navigator.msSaveBlob) {
                window.navigator.msSaveBlob(canvas.msToBlob(), name);
            } else {
                const a = document.createElement("a");
                document.body.appendChild(a);
                a.style = "display: none";
                a.href = canvas.toDataURL();
                a.download = name;
                a.click();
                document.body.removeChild(a);
            }
     });

The error may have occurred if your table doesn't have a primary key, in this case the table is "read only", and the db.SaveChanges () command will always error.

Using fetch for example like below:

 fetch(<"yoururl">, {
    method: 'GET',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer ' + <your access token if need>
    },
       })
.then((response) => response.blob())
.then((blob) => {
// 2. Create blob link to download
 const url = window.URL.createObjectURL(new Blob([blob]));
const link = document.createElement('a');
link.href = url;
link.setAttribute('download', `sample.xlsx`);
 // 3. Append to html page
 document.body.appendChild(link);
 // 4. Force download
 link.click();
 // 5. Clean up and remove the link
 link.parentNode.removeChild(link);
})

You can paste in on Chrome console to test. the file with download with 'sample.xlsx' Hope it can help!

I had multiple dataframes with different floating point, so thx to Allans idea made dynamic length.

pd.set_option('display.float_format', lambda x: f'%.{len(str(x%1))-2}f' % x)

The minus of this is that if You have last 0 in float, it will cut it. So it will be not 0.000070, but 0.00007.

This would get you the index of the clicked row, starting with one:

$('#thetable').find('tr').click( function(){_x000D_
alert('You clicked row '+ ($(this).index()+1) );_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<table id="thetable">_x000D_
   <tr>_x000D_
      <td>1</td><td>1</td><td>1</td>_x000D_
   </tr>_x000D_
   <tr>_x000D_
      <td>2</td><td>2</td><td>2</td>_x000D_
   </tr>_x000D_
   <tr>_x000D_
      <td>3</td><td>3</td><td>3</td>_x000D_
   </tr>_x000D_
</table>

If you want to return the number stored in that first cell of each row:

$('#thetable').find('tr').click( function(){
  var row = $(this).find('td:first').text();
  alert('You clicked ' + row);
});

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

In NodeJS if you know the ID, the looping through the array is very slow compared to object[ID].

const uniqueString = require('unique-string');
const obj = {};
const arr = [];
var seeking;

//create data
for(var i=0;i<1000000;i++){
  var getUnique = `${uniqueString()}`;
  if(i===888555) seeking = getUnique;
  arr.push(getUnique);
  obj[getUnique] = true;
}

//retrieve item from array
console.time('arrTimer');
for(var x=0;x<arr.length;x++){
  if(arr[x]===seeking){
    console.log('Array result:');
    console.timeEnd('arrTimer');
    break;
  }
}

//retrieve item from object
console.time('objTimer');
var hasKey = !!obj[seeking];
console.log('Object result:');
console.timeEnd('objTimer');

And the results:

Array result:
arrTimer: 12.857ms
Object result:
objTimer: 0.051ms

Even if the seeking ID is the first one in the array/object:

Array result:
arrTimer: 2.975ms
Object result:
objTimer: 0.068ms

In this specific case (mod 7), we still can replace %7 with bitwise operators:

// Return X%7 for X >= 0.
int mod7(int x)
{
  while (x > 7) x = (x&7) + (x>>3);
  return (x == 7)?0:x;
}

It works because 8%7 = 1. Obviously, this code is probably less efficient than a simple x%7, and certainly less readable.

AFAIK you will need at least a little bit of JavaScript...

I would suggest to use jQuery.

You can include this library in one line. And then you can access your div with

$('div').click(function(){
  // do stuff here
});

and respond to the click event.

Yes it will render faster, slightly, only because it doesn't have to render the image and is one less element to sort on the screen.

If you don't want it loaded, leave a DIV empty where you can load html into it later containing an <img> tag.

Try using firebug or wireshark as I've mentioned before and you'll see that the files DO get transferred even if display:none is present.

Opera is the only browser which will not load the image if the display is set to none. Opera has now moved to webkit and will render all images even if their display is set to none.

Here is a testing page that will prove it:

http://www.quirksmode.org/css/displayimg.html

If all of these rows are related and you need to alter the tabular data ... why not just wrap the entire table in a form, and change GET to POST (unless you know that you're not going to be sending more than the max amount of data a GET request can send).

I cannot wrap the entire table in a form, because some input fields of each row are input type="file" and files may be large. When the user submits the form, I want to POST only fields of current row, not all fields of the all rows which may have unneeded huge files, causing form to submit very slowly.

So, I tried incorrect nesting: tr/form and form/tr. However, it works only when one does not try to add new inputs dynamically into the form. Dynamically added inputs will not belong to incorrectly nested form, thus won't get submitted. (valid form/table dynamically inputs are submitted just fine).

Nesting div[display:table]/form/div[display:table-row]/div[display:table-cell] produced non-uniform widths of grid columns. I managed to get uniform layout when I replaced div[display:table-row] to form[display:table-row] :

div.grid {
    display: table;
}

div.grid > form {
    display: table-row;


div.grid > form > div {
    display: table-cell;
}
div.grid > form > div.head {
    text-align: center;
    font-weight: 800;
}

For the layout to be displayed correctly in IE8:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...
<meta http-equiv="X-UA-Compatible" content="IE=8, IE=9, IE=10" />

Sample of output:

<div class="grid" id="htmlrow_grid_item">
<form>
    <div class="head">Title</div>
    <div class="head">Price</div>
    <div class="head">Description</div>
    <div class="head">Images</div>
    <div class="head">Stock left</div>
    <div class="head">Action</div>
</form>
<form action="/index.php" enctype="multipart/form-data" method="post">
    <div title="Title"><input required="required" class="input_varchar" name="add_title" type="text" value="" /></div>

It would be much harder to make this code work in IE6/7, however.

If you have a 64 bit windows OS, pointing the JAVA_HOME system variable to

C:\Program Files (x86)\Java\jdk1.7.0_21

Will work when

C:\Program Files\Java\jdk1.7.0_21

fails to work.

The standard ERB templating system may work for your scenario.

def merge_into_string(animal, second_animal, action)
  template = 'The <%=animal%> <%=action%> the <%=second_animal%>'
  ERB.new(template).result(binding)
end

merge_into_string('tiger', 'deer', 'eats')
=> "The tiger eats the deer"

merge_into_string('bird', 'worm', 'finds')
=> "The bird finds the worm"

I stumbled across this question and developed a more concise version of Elliot BOnneville's answer:

var conceptName = $('#aioConceptName :selected').text();

or generically:

$('#id :pseudoclass')

This saves you an extra jQuery call, selects everything in one shot, and is more clear (my opinion).

This example is everyday, once around 9am and once around 5pm. (edited per comments).

To add to what joshb has stated already - this works just fine for me. Make sure to add references to Microsoft.Expression.Interactions.dll and System.Windows.Interactivity.dll and in your xaml do:

    xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"

I ended up using something like this for my needs. This shows that you can also pass a custom parameter:

<i:Interaction.Triggers>
            <i:EventTrigger EventName="SelectionChanged">

                <i:InvokeCommandAction Command="{Binding Path=DataContext.RowSelectedItem, RelativeSource={RelativeSource AncestorType={x:Type Window}}}" 
                                       CommandParameter="{Binding Path=SelectedItem, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}}" />
            </i:EventTrigger>
</i:Interaction.Triggers>

The Merge method takes the values from the second table and merges them in with the first table, so the first will now hold the values from both.

If you want to preserve both of the original tables, you could copy the original first, then merge:

dtAll = dtOne.Copy();
dtAll.Merge(dtTwo);

If you prefer sympy you can use nsolve.

>>> nsolve([x+y**2-4, exp(x)+x*y-3], [x, y], [1, 1])
[0.620344523485226]
[1.83838393066159]

The first argument is a list of equations, the second is list of variables and the third is an initial guess.

You are using an inline table value function. Therefore you must use Select * From function. If you want to use select function() you must use a scalar function.

https://msdn.microsoft.com/fr-fr/library/ms186755%28v=sql.120%29.aspx

You could put the body of your script into a function and then you could return from that function.

def main():
  done = True
  if done:
    return
    # quit/stop/exit
  else:
    # do other stuff

if __name__ == "__main__":
  #Run as main program
  main()

Actually, even if your variable (SongLength) is numeric, you will still have to format it with %s in order to bind the parameter correctly. If you try to use %d, you will get an error. Here's a small excerpt from this link http://mysql-python.sourceforge.net/MySQLdb.html:

To perform a query, you first need a cursor, and then you can execute queries on it:

c=db.cursor()
max_price=5
c.execute("""SELECT spam, eggs, sausage FROM breakfast
          WHERE price < %s""", (max_price,))

In this example, max_price=5 Why, then, use %s in the string? Because MySQLdb will convert it to a SQL literal value, which is the string '5'. When it's finished, the query will actually say, "...WHERE price < 5".

I have some additions to above mentioned answers Its infact a hack mentioned by Jesse Wilson from okhttp, square here. According to this hack, i had to rename my SSLSocketFactory variable to

private SSLSocketFactory delegate;

This is my TLSSocketFactory class

public class TLSSocketFactory extends SSLSocketFactory {

private SSLSocketFactory delegate;

public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
    SSLContext context = SSLContext.getInstance("TLS");
    context.init(null, null, null);
    delegate = context.getSocketFactory();
}

@Override
public String[] getDefaultCipherSuites() {
    return delegate.getDefaultCipherSuites();
}

@Override
public String[] getSupportedCipherSuites() {
    return delegate.getSupportedCipherSuites();
}

@Override
public Socket createSocket() throws IOException {
    return enableTLSOnSocket(delegate.createSocket());
}

@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(s, host, port, autoClose));
}

@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port, localHost, localPort));
}

@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(address, port, localAddress, localPort));
}

private Socket enableTLSOnSocket(Socket socket) {
    if(socket != null && (socket instanceof SSLSocket)) {
        ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
    }
    return socket;
}
}

and this is how i used it with okhttp and retrofit

 OkHttpClient client=new OkHttpClient();
    try {
        client = new OkHttpClient.Builder()
                .sslSocketFactory(new TLSSocketFactory())
                .build();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

I think you can use the overload of Regex.Replace to specify the maximum number of times to replace...

var regex = new Regex(Regex.Escape("o"));
var newText = regex.Replace("Hello World", "Foo", 1);

Use iloc to access by position (rather than label):

In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])

In [12]: df
Out[12]: 
   A  B
a  1  2
b  3  4

In [13]: df.iloc[0]  # first row in a DataFrame
Out[13]: 
A    1
B    2
Name: a, dtype: int64

In [14]: df['A'].iloc[0]  # first item in a Series (Column)
Out[14]: 1

This should be your answer

<div align="center">
 <img src="@Url.Content("~/images/image3.bmp")" alt="" align="right" style="float:right"/>
 <img src="@Url.Content("~/images/image1.bmp")" alt="" align="left" style="float:left" />
 <div id="content" align="center"> 
     <img src="@Url.Content("~/images/image2.bmp")" alt="" align="center" />
 </div>
 </div>

If you have source as a string like "abcd" and want to produce a list like this:

{ "a.a" },
{ "b.b" },
{ "c.c" },
{ "d.d" }

then call:

List<string> list = source.Select(c => String.Concat(c, ".", c)).ToList();

You can use simple color resources, specified usually inside

res/values/colors.xml.

use

<color name="red">#ffff0000</color>

and use this via android:background="@color/red". This color can be used anywhere else too, e.g. as a text color. Reference it in XML the same way, or get it in code via

getResources().getColor(R.color.red).

You can also use any drawable resource as a background, use android:background="@drawable/mydrawable" for this (that means 9patch drawables, normal bitmaps, shape drawables, ..).

you can store your array using group_Concat like that

 INSERT into Table1 (fruits)  (SELECT GROUP_CONCAT(fruit_name) from table2)
 WHERE ..... //your clause here

HERE an example in fiddle

After adding the cordova-plugin-whitelist, you must tell your application to allow access all the web-page links or specific links, if you want to keep it specific.

You can simply add this to your config.xml, which can be found in your application's root directory:

Recommended in the documentation:

<allow-navigation href="http://example.com/*" />

or:

<allow-navigation href="http://*/*" />

From the plugin's documentation:

Navigation Whitelist

Controls which URLs the WebView itself can be navigated to. Applies to top-level navigations only.

Quirks: on Android it also applies to iframes for non-http(s) schemes.

By default, navigations only to file:// URLs, are allowed. To allow other other URLs, you must add tags to your config.xml:

<!-- Allow links to example.com -->
<allow-navigation href="http://example.com/*" />

<!-- Wildcards are allowed for the protocol, as a prefix
     to the host, or as a suffix to the path -->
<allow-navigation href="*://*.example.com/*" />

<!-- A wildcard can be used to whitelist the entire network,
     over HTTP and HTTPS.
     *NOT RECOMMENDED* -->
<allow-navigation href="*" />

<!-- The above is equivalent to these three declarations -->
<allow-navigation href="http://*/*" />
<allow-navigation href="https://*/*" />
<allow-navigation href="data:*" />

I tried the above IIS configuration tricks and loopback registry hack, and I reviewed and recreated app pool permissions and a dozen other things and still wasn't able to get rid of the authentication loop running on my development workstation with IIS Express or IIS 7.5, from a local or remote browsing session. I received four 401.2 status responses and a blank page. The exact same site deployed to my IIS 8.5 staging server works flawlessly.

Finally I noticed markup in the Response Body that was rendered blank by the browser contained the default page for a successful log in. I determined that Custom Error handling for ASP.NET and HTTP for the 401 error was preventing/interfering with Windows Authentication my workstation but not the staging server. I spent several hours fiddling with this, but as soon as I removed custom handling for just the 401 error, the workstation was back to normal. I present this as yet one another way to shoot your own foot.

for me the default search in chrome was locked by smartsputnik.ru. and deleting all the entries in registry and also resetting and reinstalling chrome did not helped . except the below solution.

1. Delete related key from the registry entry- Computer\HKEY_LOCAL_MACCHINE\SOFTWARE\Policies\Google\Chrome
2. Delete file - C:\Windows\System32\GroupPolicy\Machine\registry.pol
3. Restart computer and the problem will be solved

npm has an official page about fixing npm permissions when you get the EACCES (Error: Access) error. The page even has a video.

You can fix this problem using one of two options:

1. Change the permission to npm's default directory.
2. Change npm's default directory to another directory.

Please use ListFragment. Otherwise, it won't work.

EDIT 1: Then you'll only need setListAdapter() and getListView().

Most of the other answers are a little complex for me on this question (I'm new to C#), so I am writing mine:

I have a WPF application and have defined a worker as below:

Issue:

BackgroundWorker workerAllocator;
workerAllocator.DoWork += delegate (object sender1, DoWorkEventArgs e1) {
    // This is my DoWork function.
    // It is given as an anonymous function, instead of a separate DoWork function

    // I need to update a message to textbox (txtLog) from this thread function

    // Want to write below line, to update UI
    txt.Text = "my message"

    // But it fails with:
    //  'System.InvalidOperationException':
    //  "The calling thread cannot access this object because a different thread owns it"
}

Solution:

workerAllocator.DoWork += delegate (object sender1, DoWorkEventArgs e1)
{
    // The below single line works
    txtLog.Dispatcher.BeginInvoke((Action)(() => txtLog.Text = "my message"));
}

I am yet to find out what the above line means, but it works.

For WinForms:

Solution:

txtLog.Invoke((MethodInvoker)delegate
{
    txtLog.Text = "my message";
});

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?

You could check in the following way (extra = and making length a truthy evaluation)

if (typeof(sub.from) !== 'undefined' && sub.from.length) {

[update]

I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:

for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
            mainid = sub.from[i]['id'];
            var sub = afcHelper_Submissions[mainid]; // <== re setting sub

My guess is that the error is not on the if statement but on the for(i... statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).

Since you have only one parameter, you could try decorating it with the [FromBody] attribute, or change the method to accept a DTO with value as a property, as I suggested here: MVC4 RC WebApi parameter binding

UPDATE: The official ASP.NET site was updated today with an excellent explanation: https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/sending-html-form-data-part-1

In a nutshell, when sending a single simple type in the body, send just the value prefixed with an equal sign (=), e.g. body:

=test

The shortest answer is first run the fastboot command (in my ubuntu case i.e. ./fastboot-linux oem unlock) (here i'm using ubuntu 12.04 and rooting nexus4) then power on your device in fastboot mode (in nexus 4 by pressing vol-down-key and power button)

GET vs. POST

1) Both GET and POST create an array (e.g. array( key => value, key2 => value2, key3 => value3, ...)). This array holds key/value pairs, where keys are the names of the form controls and values are the input data from the user.

2) Both GET and POST are treated as $_GET and $_POST. These are superglobals, which means that they are always accessible, regardless of scope - and you can access them from any function, class or file without having to do anything special.

3) $_GET is an array of variables passed to the current script via the URL parameters.

4) $_POST is an array of variables passed to the current script via the HTTP POST method.

When to use GET?

Information sent from a form with the GET method is visible to everyone (all variable names and values are displayed in the URL). GET also has limits on the amount of information to send. The limitation is about 2000 characters. However, because the variables are displayed in the URL, it is possible to bookmark the page. This can be useful in some cases.

GET may be used for sending non-sensitive data.

Note: GET should NEVER be used for sending passwords or other sensitive information!

When to use POST?

Information sent from a form with the POST method is invisible to others (all names/values are embedded within the body of the HTTP request) and has no limits on the amount of information to send.

Moreover POST supports advanced functionality such as support for multi-part binary input while uploading files to server.

However, because the variables are not displayed in the URL, it is not possible to bookmark the page.

Int32 unixTimestamp = (Int32)(TIME.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;

"TIME" is the DateTime object that you would like to get the unix timestamp for.

If you don't need a custom ThreadPool but you rather want to limit the number of concurrent tasks, you can use:

List<Path> paths = List.of("/path/file1.csv", "/path/file2.csv", "/path/file3.csv").stream().map(e -> Paths.get(e)).collect(toList());
List<List<Path>> partitions = Lists.partition(paths, 4); // Guava method

partitions.forEach(group -> group.parallelStream().forEach(csvFilePath -> {
       // do your processing   
}));

(Duplicate question asking for this is locked, so please bear me here)

Solution that preserves unhandled arguments. Demos Included.

Here is my solution. It is VERY flexible and unlike others, shouldn't require external packages and handles leftover arguments cleanly.

Usage is: ./myscript -flag flagvariable -otherflag flagvar2

All you have to do is edit the validflags line. It prepends a hyphen and searches all arguments. It then defines the next argument as the flag name e.g.

./myscript -flag flagvariable -otherflag flagvar2
echo $flag $otherflag
flagvariable flagvar2

The main code (short version, verbose with examples further down, also a version with erroring out):

#!/usr/bin/env bash
#shebang.io
validflags="rate time number"
count=1
for arg in $@
do
    match=0
    argval=$1
    for flag in $validflags
    do
        sflag="-"$flag
        if [ "$argval" == "$sflag" ]
        then
            declare $flag=$2
            match=1
        fi
    done
        if [ "$match" == "1" ]
    then
        shift 2
    else
        leftovers=$(echo $leftovers $argval)
        shift
    fi
    count=$(($count+1))
done
#Cleanup then restore the leftovers
shift $#
set -- $leftovers

The verbose version with built in echo demos:

#!/usr/bin/env bash
#shebang.io
rate=30
time=30
number=30
echo "all args
$@"
validflags="rate time number"
count=1
for arg in $@
do
    match=0
    argval=$1
#   argval=$(echo $@ | cut -d ' ' -f$count)
    for flag in $validflags
    do
            sflag="-"$flag
        if [ "$argval" == "$sflag" ]
        then
            declare $flag=$2
            match=1
        fi
    done
        if [ "$match" == "1" ]
    then
        shift 2
    else
        leftovers=$(echo $leftovers $argval)
        shift
    fi
    count=$(($count+1))
done

#Cleanup then restore the leftovers
echo "pre final clear args:
$@"
shift $#
echo "post final clear args:
$@"
set -- $leftovers
echo "all post set args:
$@"
echo arg1: $1 arg2: $2

echo leftovers: $leftovers
echo rate $rate time $time number $number

Final one, this one errors out if an invalid -argument is passed through.

#!/usr/bin/env bash
#shebang.io
rate=30
time=30
number=30
validflags="rate time number"
count=1
for arg in $@
do
    argval=$1
    match=0
        if [ "${argval:0:1}" == "-" ]
    then
        for flag in $validflags
        do
                sflag="-"$flag
            if [ "$argval" == "$sflag" ]
            then
                declare $flag=$2
                match=1
            fi
        done
        if [ "$match" == "0" ]
        then
            echo "Bad argument: $argval"
            exit 1
        fi
        shift 2
    else
        leftovers=$(echo $leftovers $argval)
        shift
    fi
    count=$(($count+1))
done
#Cleanup then restore the leftovers
shift $#
set -- $leftovers
echo rate $rate time $time number $number
echo leftovers: $leftovers

Pros: What it does, it handles very well. It preserves unused arguments which a lot of the other solutions here don't. It also allows for variables to be called without being defined by hand in the script. It also allows prepopulation of variables if no corresponding argument is given. (See verbose example).

Cons: Can't parse a single complex arg string e.g. -xcvf would process as a single argument. You could somewhat easily write additional code into mine that adds this functionality though.

In IIS10 (Windows 10 and Server 2016), from version 1709 onwards, there is a new, simpler option for enabling HSTS for a website.

Microsoft describe the advantages of the new approach here, and provide many different examples of how to implement the change programmatically or by directly editing the ApplicationHost.config file (which is like web.config but operates at the IIS level, rather than individual site level). ApplicationHost.config can be found in C:\Windows\System32\inetsrv\config.

I've outlined two of the example methods here to avoid link rot.

Method 1 - Edit the ApplicationHost.config file directly Between the <site> tags, add this line:

<hsts enabled="true" max-age="31536000" includeSubDomains="true" redirectHttpToHttps="true" />

Method 2 - Command Line: Execute the following from an elevated command prompt (i.e. right mouse on CMD and run as administrator). Remember to swap Contoso with the name of your site as it appears in IIS Manager.

c:
cd C:\WINDOWS\system32\inetsrv\
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.enabled:True" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.max-age:31536000" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.includeSubDomains:True" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.redirectHttpToHttps:True" /commit:apphost

The other methods Microsoft offer in that articles might be better options if you are on a hosted environment where you have limited access.

Keep in mind that IIS10 version 1709 is available on Windows 10 now, but for Windows Server 2016 it is on a different release track, and won't be released as a patch or service pack. See here for details about 1709.

Difference Between ClassNotFoundException Vs NoClassDefFoundError

If you know there won't be more than a certain number of spaces in a row, you could just nest the replace:

replace(replace(replace(replace(myText,'  ',' '),'  ',' '),'  ',' '),'  ',' ')

4 replaces should fix up to 16 consecutive spaces (16, then 8, then 4, then 2, then 1)

If it could be significantly longer, then you'd have to do something like an in-line function:

CREATE FUNCTION strip_spaces(@str varchar(8000))
RETURNS varchar(8000) AS
BEGIN 
    WHILE CHARINDEX('  ', @str) > 0 
        SET @str = REPLACE(@str, '  ', ' ')

    RETURN @str
END

Then just do

SELECT dbo.strip_spaces(myText) FROM myTable

In my case the only work solution was:

1. CREATE TABLE bad_table ENGINE=MyISAM ...
2. rm bad_table.ibd
3. DROP TABLE bad_table

I see the question is about Express Edition, but this topic is easy to pop up in Google Search, and doesn't have a solution for other editions.

So. If you run into this problem with any VS Edition except Express, you can rerun installation and include MFC files.

@dibrovsd: Solution will not work if the xml have more than one tag with same name

On your line of thought, I have modified the code a bit and written it for general node instead of root:

from collections import defaultdict
def xml2dict(node):
    d, count = defaultdict(list), 1
    for i in node:
        d[i.tag + "_" + str(count)]['text'] = i.findtext('.')[0]
        d[i.tag + "_" + str(count)]['attrib'] = i.attrib # attrib gives the list
        d[i.tag + "_" + str(count)]['children'] = xml2dict(i) # it gives dict
     return d

I found several functions defined in http://tw1.php.net/unpack are very useful.
They can covert string to byte array and vice versa.

Take byteStr2byteArray() as an example:

<?php
function byteStr2byteArray($s) {
    return array_slice(unpack("C*", "\0".$s), 1);
}

$msg = "abcdefghijk";
$byte_array = byteStr2byteArray($msg);

for($i=0;$i<count($byte_array);$i++)
{
   printf("0x%02x ", $byte_array[$i]);
}
?>

For debugging Twig templates you can use the debug statement.

There you can set the debug setting explicitely.

I believe in order to have auto-wiring work on your MyLauncher class (for myService), you will need to let Spring initialize it instead of calling the constructor, by auto-wiring myLauncher. Once that is being auto-wired (and myService is also getting auto-wired), Spring (1.4.0 and up) provides a @MockBean annotation you can put in your test. This will replace a matching single beans in context with a mock of that type. You can then further define what mocking you want, in a @Before method.

public class MyLauncherTest
    @MockBean
    private MyService myService;

    @Autowired
    private MyLauncher myLauncher;

    @Before
    private void setupMockBean() {
        doNothing().when(myService).someVoidMethod();
        doReturn("Some Value").when(myService).someStringMethod();
    }

    @Test
    public void someTest() {
        myLauncher.doSomething();
    }
}

Your MyLauncher class can then remain unmodified, and your MyService bean will be a mock whose methods return values as you defined:

@Component
public class MyLauncher {
    @Autowired
    MyService myService;

    public void doSomething() {
        myService.someVoidMethod();
        myService.someMethodThatCallsSomeStringMethod();
    }

    //other methods
}

A couple advantages of this over other methods mentioned is that:

1. You don't need to manually inject myService.
2. You don't need use the Mockito runner or rules.

We actually have some notification code in our product that uses TLS to send mail if it is available.

You will need to set the Java Mail properties. You only need the TLS one but you might need SSL if your SMTP server uses SSL.

Properties props = new Properties();
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.auth", "true");  // If you need to authenticate
// Use the following if you need SSL
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

You can then either pass this to a JavaMail Session or any other session instantiator like Session.getDefaultInstance(props).

Here's one more version to try for those having issues with the others. It pulls together the techniques discussed in this duplicate question, and generates the required helper DIVs dynamically so no extra HTML is required.

CSS:

.sticky { position:fixed; top:0; }

JQuery:

function make_sticky(id) {
    var e = $(id);
    var w = $(window);
    $('<div/>').insertBefore(id);
    $('<div/>').hide().css('height',e.outerHeight()).insertAfter(id);
    var n = e.next();
    var p = e.prev();
    function sticky_relocate() {
      var window_top = w.scrollTop();
      var div_top = p.offset().top;
      if (window_top > div_top) {
        e.addClass('sticky');
        n.show();
      } else {
        e.removeClass('sticky');
        n.hide();
      }
    }
    w.scroll(sticky_relocate);
    sticky_relocate();
}

To make an element sticky, do:

make_sticky('#sticky-elem-id');

When the element becomes sticky, the code manages the position of the remaining content to keep it from jumping into the gap left by the sticky element. It also returns the sticky element to its original non-sticky position when scrolling back above it.

This answer doesn't help for SQL databases where SharePoint is connected. db_securityadmin is required for the configuration databases. In order to add db_securityadmin, you will need to change the owner of the database to an administrative account. You can use that account just for dbo roles.

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

base64.b16encode and base64.b16decode convert bytes to and from hex and work across all Python versions. The codecs approach also works, but is less straightforward in Python 3.

You can just use strstr() from <string.h>

$ man strstr

&& means "and if successful"; by placing your if statement on the right-hand side of it, you ensure that it will only run if grep returns 0. To fix it, use ; instead:

ps aux | grep some_proces[s] > /tmp/test.txt ; if [ $? -eq 0 ]; then echo 1; else echo 0; fi

(or just use a line-break).

SET session_replication_role = replica;  

also dosent work for me in Postgres 9.1. i use the two function described by bartolo-otrit with some modification. I modified the first function to make it work for me because the namespace or the schema must be present to identify the table correctly. The new code is :

CREATE OR REPLACE FUNCTION disable_triggers(a boolean, nsp character varying)
  RETURNS void AS
$BODY$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_namespace n
        join pg_class c on c.relnamespace = n.oid and c.relhastriggers = true
        where n.nspname = nsp
    loop
        execute format('alter table %I.%I %s trigger all', nsp,r.relname, act); 
    end loop;
end;
$BODY$
  LANGUAGE plpgsql VOLATILE
  COST 100;
ALTER FUNCTION disable_triggers(boolean, character varying)
  OWNER TO postgres;

then i simply do a select query for every schema :

SELECT disable_triggers(true,'public');
SELECT disable_triggers(true,'Adempiere');

Use getopt

Why getopt?

To parse elaborated command-line arguments to avoid confusion and clarify the options we are parsing so that reader of the commands can understand what's happening.

What is getopt?

getopt is used to break up (parse) options in command lines for easy parsing by shell procedures, and to check for legal options. It uses the GNU getopt(3) routines to do this.

getopt can have following types of options.

1. No-value options
2. key-value pair options

Note: In this document, during explaining syntax:

• Anything inside [ ] is optional parameter in the syntax/examples.
• is a place holder, which mean it should be substituted with an actual value.

HOW TO USE getopt?

Syntax: First Form

getopt optstring parameters

Examples:

# This is correct
getopt "hv:t::" "-v 123 -t123"  
getopt "hv:t::" "-v123 -t123"  # -v and 123 doesn't have whitespace

# -h takes no value.
getopt "hv:t::" "-h -v123"


# This is wrong. after -t can't have whitespace.
# Only optional params cannot have whitespace between key and value
getopt "hv:t::" "-v 123 -t 123"

# Multiple arguments that takes value.
getopt "h:v:t::g::" "-h abc -v 123 -t21"

# Multiple arguments without value
# All of these are correct
getopt "hvt" "-htv"
getopt "hvt" "-h -t -v"
getopt "hvt" "-tv -h"

Here h,v,t are the options and -h -v -t is how options should be given in command-line.

1. 'h' is a no-value option.
2. 'v:' implies that option -v has value and is a mandatory option. ':' means has a value.
3. 't::' implies that option -t has value but is optional. '::' means optional.

In optional param, value cannot have whitespace separation with the option. So, in "-t123" example, -t is option 123 is value.

Syntax: Second Form

getopt [getopt_options] [--] [optstring] [parameters]

Here after getopt is split into five parts

• The command itself i.e. getopt
• The getopt_options, it describes how to parse the arguments. single dash long options, double dash options.
• --, separates out the getopt_options from the options you want to parse and the allowed short options
• The short options, is taken immediately after -- is found. Just like the Form first syntax.
• The parameters, these are the options that you have passed into the program. The options you want to parse and get the actual values set on them.

Examples

getopt -l "name:,version::,verbose" -- "n:v::V" "--name=Karthik -version=5.2 -verbose"

Syntax: Third Form

getopt [getopt_options] [-o options] [--] [optstring] [parameters]

Here after getopt is split into five parts

• The command itself i.e. getopt
• The getopt_options, it describes how to parse the arguments. single dash long options, double dash options.
• The short options i.e. -o or --options. Just like the Form first syntax but with option "-o" and before the "--" (double dash).
• --, separates out the getopt_options from the options you want to parse and the allowed short options
• The parameters, these are the options that you have passed into the program. The options you want to parse and get the actual values set on them.

Examples

getopt -l "name:,version::,verbose" -a -o "n:v::V" -- "-name=Karthik -version=5.2 -verbose"

GETOPT_OPTIONS

getopt_options changes the way command-line params are parsed.

Below are some of the getopt_options

Option: -l or --longoptions

Means getopt command should allow multi-character options to be recognised. Multiple options are separated by comma.

For example, --name=Karthik is a long option sent in command line. In getopt, usage of long options are like

getopt "name:,version" "--name=Karthik"

Since name: is specified, the option should contain a value

Option: -a or --alternative

Means getopt command should allow long option to have a single dash '-' rather than double dash '--'.

Example, instead of --name=Karthik you could use just -name=Karthik

getopt "name:,version" "-name=Karthik"

A complete script example with the code:

#!/bin/bash

# filename: commandLine.sh
# author: @theBuzzyCoder

showHelp() {
# `cat << EOF` This means that cat should stop reading when EOF is detected
cat << EOF  
Usage: ./installer -v <espo-version> [-hrV]
Install Pre-requisites for EspoCRM with docker in Development mode

-h, -help,          --help                  Display help

-v, -espo-version,  --espo-version          Set and Download specific version of EspoCRM

-r, -rebuild,       --rebuild               Rebuild php vendor directory using composer and compiled css using grunt

-V, -verbose,       --verbose               Run script in verbose mode. Will print out each step of execution.

EOF
# EOF is found above and hence cat command stops reading. This is equivalent to echo but much neater when printing out.
}


export version=0
export verbose=0
export rebuilt=0

# $@ is all command line parameters passed to the script.
# -o is for short options like -v
# -l is for long options with double dash like --version
# the comma separates different long options
# -a is for long options with single dash like -version
options=$(getopt -l "help,version:,verbose,rebuild,dryrun" -o "hv:Vrd" -a -- "$@")

# set --:
# If no arguments follow this option, then the positional parameters are unset. Otherwise, the positional parameters 
# are set to the arguments, even if some of them begin with a ‘-’.
eval set -- "$options"

while true
do
case $1 in
-h|--help) 
    showHelp

There are 3 things you need.

1. You need to oAuth with the owner of those photos. (with the 'user_photos' extended permission)

2. You need the access token (which you get returned in the URL box after the oAuth is done.)

3. When those are complete you can then access the photos like so https://graph.facebook.com/me?access_token=ACCESS_TOKEN

You can find all of the information in more detail here: http://developers.facebook.com/docs/authentication

this always refers to currently executing object.

To further illustrate the point here is a simple sketch:

+----------------+
|  Subclass      |
|----------------|
|  @method1()    |
|  @method2()    |
|                |
| +------------+ |
| | Superclass | |
| |------------| |
| | method1()  | |
| | method2()  | |
| +------------+ |
+----------------+

If you have an instance of the outer box, a Subclass object, wherever you happen to venture inside the box, even into the Superclass 'area', it is still the instance of the outer box.

What's more, in this program there is only one object that gets created out of the three classes, so this can only ever refer to one thing and it is:

as shown in the Netbeans 'Heap Walker'.

Unless there is a strong advantage to running your user form in Excel then I would go with a 100% Access solution that would export the reports and data to Excel on an ad-hoc basis.

From what you describe, Access seems the stronger contender as it is built for working with data:
you would have a lot more tools at your disposal to solve any data problems than have to go around the limitations of Excel and shoehorn it into becoming Access...

As for your questions:

1. Very easy. There have been some other questions on SO on that subject.
   See for instance this one and that one.

2. Don't know, but I would guess that there could be a small penalty.
   The biggest difficulty I see is trying to get all the functionalities that Access gives you and re-creating some of these in Excel.

3. Yes, you can have multiple Excel users and a single Access database.
   Here again, using Access as a front-end and keeping the data in a linked Access database on your network would make more sense and it's easy as pie, there's even a wizard in Access to help you do that: it's just 1 click away.

Really, as most other people have said, take a tiny bit of time to get acquainted with Access, it will save you a lot of time and trouble.
You may know Excel better but if you've gone 80% of the way already if you know VBA and are familiar with the Office object model.

Other advantages of doing it in Access: the Access 2007 runtime is free, meaning that if you were to deploy to app to 1 or 30 PC it would cost you the same: nothing.
You only need one full version of Access for your development work (the Runtime doesn't have the designers).

For the sake of completeness, I am posting a solution using heapq. Note, this method will work for both numeric and non-numeric values

>>> x = {1: 2, 3: 4, 4:3, 2:1, 0:0}
>>> x_items = x.items()
>>> heapq.heapify(x_items)
>>> #To sort in reverse order
>>> heapq.nlargest(len(x_items),x_items, operator.itemgetter(1))
[(3, 4), (4, 3), (1, 2), (2, 1), (0, 0)]
>>> #To sort in ascending order
>>> heapq.nsmallest(len(x_items),x_items, operator.itemgetter(1))
[(0, 0), (2, 1), (1, 2), (4, 3), (3, 4)]

pip install --ignore-installed six

Would do the trick.

Please see below typescript for re-applying css class again to an element to override parent container (usually a framework component) css styles and force your custom styles. Your app framework (be it angular/react, probably does this so the parent container css was re-applied and none of your expected effects in css-class-name is showing up for your child element. Call this.overrideParentCssRule(childElement, 'css-class-name'); to do what the framework just did (call this in document.ready or end of event handler):

      overrideParentCssRule(elem: HTMLElement, className: string) {
        let cssRules = this.getCSSStyle(className);
        for (let r: number = 0; r < cssRules.length; r++) {
          let rule: CSSStyleRule = cssRules[r];
          Object.keys(rule.style).forEach(s => {
            if (isNaN(Number(s)) && rule.style[s]) {
              elem.style[s] = rule.style[s];
            }
          });
        }
      }

Use this pattern,

pattern = '\[P\].+?\[\/P\]'

Check here

Just use jquery :

jQuery( document ).ready(function( $ ) {

   //Use this inside your document ready jQuery 
   $(window).on('popstate', function() {
      location.reload(true);
   });

});

The above will work 100% when back or forward button has been clicked using ajax as well.

if it doesn't, there must be a misconfiguration in a different part of the script.

For example it might not reload if something like one of the example in the previous post is used window.history.pushState('', null, './');

so when you do use history.pushState(); make sure you use it properly.

Suggestion in most cases you will just need:

history.pushState(url, '', url); 

No window.history... and make sure url is defined.

Hope that helps..

Nirsoft's NirCMD can create shortcuts from a command line, too. (Along with a pile of other functions.) Free and available here:

http://www.nirsoft.net/utils/nircmd.html

Full instructions here: http://www.nirsoft.net/utils/nircmd2.html#using (Scroll down to the "shortcut" section.)

Yes, using nircmd does mean you are using another 3rd-party .exe, but it can do some functions not in (most of) the above solutions (e.g., pick a icon # in a dll with multiple icons, assign a hot-key, and set the shortcut target to be minimized or maximized).

Though it appears that the shortcutjs.bat solution above can do most of that, too, but you'll need to dig more to find how to properly assign those settings. Nircmd is probably simpler.

Working jsbin: http://jsbin.com/ANAYeDU/4/edit

Main bit:

function answers()
{

var element = document.getElementById("mySelect");
var elementValue = element.value;

if(elementValue == "To measure time"){
  alert("Thats correct"); 
  }
}

routes.rb
  get '*unmatched_route', to: 'main#not_found'

main_controller.rb
  def not_found
    render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false
  end

Try This :

document.getElementById(<element_ID>).readOnly=true;

This it not possible to use the CSS3 selector :first-of-type to select the first element with a given class name.

However, if the targeted element has a previous element sibling, you can combine the negation CSS pseudo-class and the adjacent sibling selectors to match an element that doesn't immediately have a previous element with the same class name :

:not(.myclass1) + .myclass1

Full working code example:

p:first-of-type {color:blue}_x000D_
p:not(.myclass1) + .myclass1 { color: red }_x000D_
p:not(.myclass2) + .myclass2 { color: green }

<div>_x000D_
  <div>This text should appear as normal</div>_x000D_
  <p>This text should be blue.</p>_x000D_
  <p class="myclass1">This text should appear red.</p>_x000D_
  <p class="myclass2">This text should appear green.</p>_x000D_
</div>

Also, on the Intel Macs, can I use generic x86 asm? or is there a modified instruction set? Any information about post Intel Mac assembly helps.

It's the same instruction set; it's the same chips.

I've found a solution in a forum, Toggle Background Img.

The above suggestions did not work for me. What really worked was the inclusion of the following lines in the application.properties

spring.datasource.testWhileIdle = true
spring.datasource.timeBetweenEvictionRunsMillis = 3600000
spring.datasource.validationQuery = SELECT 1

These do not discard the data in the stringstream in gnu c++

    m.str("");
    m.str() = "";
    m.str(std::string());

The following does empty the stringstream for me:

    m.str().clear();

Pattern whitespace = Pattern.compile("\\s\\s");
matcher = whitespace.matcher(modLine);

boolean flag = true;
while(flag)
{
 //Update your original search text with the result of the replace
 modLine = matcher.replaceAll(" ");
 //reset matcher to look at this "new" text
 matcher = whitespace.matcher(modLine);
 //search again ... and if no match , set flag to false to exit, else run again
 if(!matcher.find())
 {
 flag = false;
 }
}

Your team's advice is almost right, except for the mistake that was made. Once you find out why, you will never forget it. Take a look at this mistake.

/^(7|8|9)\d{9}$/

What this does:

• ^ and $ denotes anchored matches, which asserts that the subpattern in between these anchors are the entire match. The string will only match if the subpattern matches the entirety of it, not just a section.
• () denotes a capturing group.
• 7|8|9 denotes matching either of 7, 8, or 9. It does this with alternations, which is what the pipe operator | does — alternating between alternations. This backtracks between alternations: If the first alternation is not matched, the engine has to return before the pointer location moved during the match of the alternation, to continue matching the next alternation; Whereas the character class can advance sequentially. See this match on a regex engine with optimizations disabled:

Pattern: (r|f)at
Match string: carat

Pattern: [rf]at
Match string: carat

• \d{9} matches nine digits. \d is a shorthanded metacharacter, which matches any digits.

/^[7|8|9][\d]{9}$/

Look at what it does:

• ^ and $ denotes anchored matches as well.
• [7|8|9] is a character class. Any characters from the list 7, |, 8, |, or 9 can be matched, thus the | was added in incorrectly. This matches without backtracking.
• [\d] is a character class that inhabits the metacharacter \d. The combination of the use of a character class and a single metacharacter is a bad idea, by the way, since the layer of abstraction can slow down the match, but this is only an implementation detail and only applies to a few of regex implementations. JavaScript is not one, but it does make the subpattern slightly longer.
• {9} indicates the previous single construct is repeated nine times in total.

The optimal regex is /^[789]\d{9}$/, because /^(7|8|9)\d{9}$/ captures unnecessarily which imposes a performance decrease on most regex implementations (javascript happens to be one, considering the question uses keyword var in code, this probably is JavaScript). The use of php which runs on PCRE for preg matching will optimize away the lack of backtracking, however we're not in PHP either, so using classes [] instead of alternations | gives performance bonus as the match does not backtrack, and therefore both matches and fails faster than using your previous regular expression.

If you see your error message it says

Building in workspace /var/lib/jenkins/workspace/AutoScript

and as per your comments you have put urltest.sh in

/var/lib/jenkins

Hence Jenkins is not able to find the file. In your build step do this thing, it will work

cd             # which will point to /var/lib/jenkins
./urltest.sh   # it will run your script

If it still fails try to chown the file as jenkin user may not have file permission, but I think if you do above step you will be able to run.

Your syntax is pretty screwy.

Change this:

input:not(disabled)not:[type="submit"]:focus{

to:

input:not(:disabled):not([type="submit"]):focus{

Seems that many people don't realize :enabled and :disabled are valid CSS selectors...

Spring framework itself handles json conversion when controller is annotated properly.

For eg:

   @PutMapping(produces = {"application/json"})
        @ResponseBody
        public UpdateResponse someMethod(){ //do something
return UpdateResponseInstance;
}

Here spring internally converts the UpdateResponse object to corresponding json string and returns it. In order to do it spring internally uses Jackson library.

If you require a json representation of a model object anywhere apart from controller then you can use objectMapper provided by jackson. Model should be properly annotated for this to work.

Eg:

ObjectMapper mapper = new ObjectMapper();
SomeModelClass someModelObject = someModelRepository.findById(idValue).get();
mapper.writeValueAsString(someModelObject);

The easiest way I've found to create postscripts is the following, using the setEPS() command:

setEPS()
postscript("whatever.eps")
plot(rnorm(100), main="Hey Some Data")
dev.off()

see: https://developer.mozilla.org/en-US/docs/Web/CSS/cursor

so you need to add: cursor:pointer;

In your case use:

#more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

This will apply the curser to the element with the ID "more" (can be only used once). So in your HTML use

<input type="button" id="more" />

If you want to apply this to more than one button then you have more than one possibility:

using CLASS

.more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" class="more" value="first" />
<input type="button" class="more" value="second" />

or apply to a html context:

input[type=button] {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" value="first" />
<input type="button" value="second" />

In PS 7, you can use ConvertFrom-SecureString and -AsPlainText:

 $UnsecurePassword = ConvertFrom-SecureString -SecureString $SecurePassword -AsPlainText

https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.security/ConvertFrom-SecureString?view=powershell-7#parameters

ConvertFrom-SecureString
           [-SecureString] <SecureString>
           [-AsPlainText]
           [<CommonParameters>]

This seems like the simplest solution that I've found to retrieve the last value in an ever-expanding column:

=INDEX(A:A,COUNTA(A:A),1)

Here is the one liner i use, from terminal, to test the content of yml file(s):

$ ruby  -r yaml -r pp  -e 'pp YAML.load_file("/Users/za/project/application.yml")'
{"logging"=>
  {"path"=>"/var/logs/",
   "file"=>"TacoCloud.log",
   "level"=>
    {"root"=>"WARN", "org"=>{"springframework"=>{"security"=>"DEBUG"}}}}}

If you have firebug, there's a break on all errors option in the script tab. Once the script has hit your breakpoint, you can look at firebug's stack window:

On Windows:

Find : Ctrl+F

Find And Replace In Single Class: Ctrl+R

Find And Replace In Whole Project: Ctrl+Shift+R

on OS X ,it is similar, just replace Ctrl with Command

What I would do is put a span inside the <a> tag, set the span to block, and add size to the span, or just apply the styling to the <a> tag. Definitely handle the positioning in the <a> tag style. Add an onclick event to the a where JavaScript will catch the event, then return false at the end of the JavaScript event to prevent default action of the href and bubbling of the click. This works in cases with or without JavaScript enabled, and any AJAX can be handled in the Javascript listener.

If you're using jQuery, you can use this as your listener and omit the onclick in the a tag.

$('#idofdiv').live("click", function(e) {
    //add stuff here
    e.preventDefault; //or use return false
}); 

this allows you to attach listeners to any changed elements as necessary.

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)
    end
end)

Fantastic question. I'd love to see some best practices shown.

I've got a lot of files that I distribute, so I've set up my project into several wxs source files.

I have a top level source file which I call Product.wxs which basically contains the structure for the installation, but not the actual components. This file has several sections:

<Product ...>
  <Package ...>
    <Media>... 
   <Condition>s ...
   <Upgrade ..>
   <Directory> 
        ...
   </Directory>
   <Feature>
      <ComponentGroupRef ... > A bunch of these that
   </Feature>
   <UI ...>
   <Property...>
   <Custom Actions...>
   <Install Sequences....
  </Package>
</Product>

The rest of the .wix files are composed of Fragments that contain ComponentGroups which are referenced in the Feature tag in the Product.wxs. My project contains a nice logical grouping of the files that I distribute

<Fragment>
   <ComponentGroup>
     <ComponentRef>
     ....
    </ComponentGroup>
    <DirectoryRef>
      <Component... for each file
      .... 
    </DirectoryRef>
</Fragment>

This isn't perfect, my OO spider sense tingles a bit because the fragments have to reference names in the Product.wxs file (e.g. the DirectoryRef) but I find it easier to maintain that a single large source file.

I'd love to hear comments on this, or if anyone has any good tips too!

Instead of using

import os
dirname = os.path.dirname(__file__)
filename = os.path.join(dirname, 'relative/path/to/file/you/want')

as in the accepted answer, it would be more robust to use:

import inspect
import os
dirname = os.path.dirname(os.path.abspath(inspect.stack()[0][1]))
filename = os.path.join(dirname, 'relative/path/to/file/you/want')

because using __file__ will return the file from which the module was loaded, if it was loaded from a file, so if the file with the script is called from elsewhere, the directory returned will not be correct.

These answers give more detail: https://stackoverflow.com/a/31867043/5542253 and https://stackoverflow.com/a/50502/5542253

--get tables that contains selected columnName

its worked...

I use it in a practical sense when we transfer large binary objects (images) via web services. So when I am testing a C# web service using a python script, the binary object can be recreated with a little magic.

[In python]

Since nobody posted this, I am posting the correct answer. If your new state update depends on the previous state, always use the functional form of setState which accepts as argument a function that returns a new state.

In your case:

this.setState(prevState => ({
  check: !prevState.check
}));

See docs

Since this answer is becoming popular, adding the approach that should be used for React Hooks (v16.8+):

If you are using the useState hook, then use the following code (in case your new state depends on the previous state):

const [check, setCheck] = useState(false);
// ...
setCheck(prevCheck => !prevCheck);

function sleep(delay) {
    var start = new Date().getTime();
    while (new Date().getTime() < start + delay);
}

This code blocks for the specified duration. This is CPU hogging code. This is different from a thread blocking itself and releasing CPU cycles to be utilized by another thread. No such thing is going on here. Do not use this code, it's a very bad idea.

I wrote a cross-platform library color_ostream for this, with the support of ANSI color, 256 color and true color, all you have to do is directly including it and changing cout to rd_cout like this.
| std | basic color | 256 color | true color | | :----: | :----: | :----: | :----: | | std::cout | color_ostream::rd_cout | color_ostream::rd256_cout | color_ostream::rdtrue_cout | | std::wcout | color_ostream::rd_wcout | color_ostream::rd256_wcout | color_ostream::rdtrue_wcout | | std::cerr | color_ostream::rd_cerr | color_ostream::rd256_cerr | color_ostream::rdtrue_cerr | | std::wcerr | color_ostream::rd_wcerr | color_ostream::rd256_wcerr | color_ostream::rdtrue_wcerr | | std::clog | color_ostream::rd_clog | color_ostream::rd256_clog | color_ostream::rdtrue_clog | | std::wclog | color_ostream::rd_wclog | color_ostream::rd256_wclog | color_ostream::rdtrue_wclog |
Here is an simple example:

//hello.cpp
#include "color_ostream.h"

using namespace color_ostream;

int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[]) {
    rd_wcout.imbue(std::locale(std::locale(),"",LC_CTYPE));
    rd_wcout << L"Hello world\n";
    rd_wcout << L"Hola Mundo\n";
    rd_wcout << L"Bonjour le monde\n";

    rd256_wcout << L"\n256 color" << std::endl;
    rd256_wcout << L"Hello world\n";
    rd256_wcout << L"Hola Mundo\n";
    rd256_wcout << L"Bonjour le monde\n";

    rdtrue_wcout << L"\ntrue color" << std::endl;
    rdtrue_wcout << L"Hello world\n";
    rdtrue_wcout << L"Hola Mundo\n";
    rdtrue_wcout << L"Bonjour le monde\n";
    return 0;
}

Try the following:

• Remove \bin from JAVA_HOME path.
• Open new command line window.
• Run your command as an administrator.

Pecl PDO package is now deprecated. By the way the debian package php5-pgsql now includes both the regular and the PDO driver, so just:

apt-get install php-pgsql

Apache also needs to be restarted before sites can use it:

sudo systemctl restart apache2

If you only ever want to move one item from an arbitrary position to the end of the array, this should work:

function toEnd(list, position) {
    list.push(list.splice(position, 1));
    return list;
}

If you want to move multiple items from some arbitrary position to the end, you can do:

function toEnd(list, from, count) {
    list.push.apply(list, list.splice(from, count));
    return list;
}

If you want to move multiple items from some arbitrary position to some arbitrary position, try:

function move(list, from, count, to) {
    var args = [from > to ? to : to - count, 0];
    args.push.apply(args, list.splice(from, count));
    list.splice.apply(list, args);

    return list;
}

Here is what I'm using:

if (location.href.includes('?')) { 
    history.pushState({}, null, location.href.split('?')[0]); 
}

Original URL: http://www.example.com/test/hello?id=123&foo=bar
Destination URL: http://www.example.com/test/hello

Just make an http request to the required URL with correct query string, or request body.

For example you could use java.net.HttpURLConnection and then consume via connection.getInputStream(), and then covnert to your objects.

In spring there is a restTemplate that makes it all a bit easier.

This helper class manages parameters for GET and POST requests:

public class CustomRequest extends Request<JSONObject> {
    private int mMethod;
    private String mUrl;
    private Map<String, String> mParams;

Thank you @hobodave.

However I found two weaknesses in your code. Your parsing of the original url to get the "host" segment stops at the first single slash. This presumes that all relative links start in the root directory. This only true sometimes.

original url   :  http://example.com/game/index.html
href in <a> tag:  highscore.html
author's intent:  http://example.com/game/highscore.html  <-200->
crawler result :  http://example.com/highscore.html       <-404->

fix this by breaking at the last single slash not the first

a second unrelated bug, is that $depth does not really track recursion depth, it tracks breadth of the first level of recursion.

If I believed this page were in active use I might debug this second issue, but I suspect the text I am writing now will never be read by anyone, human or robot, since this issue is six years old and I do not even have enough reputation to notify +hobodave directly about these defects by commmenting on his code. Thanks anyway hobodave.

Create a gesture recognizer (subclass), that will implement touch events, like touchesBegan. You can add it to the view after that.

This way you'll use composition instead subclassing (which was the request).

You can add a column to your data using various techniques. The quotes below come from the "Details" section of the relevant help text, [[.data.frame.

Data frames can be indexed in several modes. When [ and [[ are used with a single vector index (x[i] or x[[i]]), they index the data frame as if it were a list.

my.dataframe["new.col"] <- a.vector
my.dataframe[["new.col"]] <- a.vector

The data.frame method for $, treats x as a list

my.dataframe$new.col <- a.vector

When [ and [[ are used with two indices (x[i, j] and x[[i, j]]) they act like indexing a matrix

my.dataframe[ , "new.col"] <- a.vector

Since the method for data.frame assumes that if you don't specify if you're working with columns or rows, it will assume you mean columns.

For your example, this should work:

# make some fake data
your.df <- data.frame(no = c(1:4, 1:7, 1:5), h_freq = runif(16), h_freqsq = runif(16))

# find where one appears and 
from <- which(your.df$no == 1)
to <- c((from-1)[-1], nrow(your.df)) # up to which point the sequence runs

# generate a sequence (len) and based on its length, repeat a consecutive number len times
get.seq <- mapply(from, to, 1:length(from), FUN = function(x, y, z) {
            len <- length(seq(from = x[1], to = y[1]))
            return(rep(z, times = len))
         })

# when we unlist, we get a vector
your.df$group <- unlist(get.seq)
# and append it to your original data.frame. since this is
# designating a group, it makes sense to make it a factor
your.df$group <- as.factor(your.df$group)


   no     h_freq   h_freqsq group

Note: This solution is better for older versions of JSTL. For versions greater then 1.1 I recommend using fn:length(MyBean.somelist) as suggested by Bill James.

This article has some more detailed information, including another possible solution;

The problem is that we are trying to invoke the list's size method (which is a valid LinkedList method), but it's not a JavaBeans-compliant getter method, so the expression list.size-1 cannot be evaluated.

There are two ways to address this dilemma. First, you can use the RT Core library, like this:

<c_rt:out value='<%= list[list.size()-1] %>'/>

Second, if you want to avoid Java code in your JSP pages, you can implement a simple wrapper class that contains a list and provides access to the list's size property with a JavaBeans-compliant getter method. That bean is listed in Listing 2.25.

The problem with c_rt method is that you need to get the variable from request manually, because it doesn't recognize it otherwise. At this point you are putting in a lot of code for what should be built in functionality. This is a GIANT flaw in the EL.

I ended up using the "wrapper" method, here is the class for it;

public class CollectionWrapper {

    Collection collection;

    public CollectionWrapper(Collection collection) {
        this.collection = collection;
    }

    public Collection getCollection() {
        return collection;
    }

    public int getSize() {
        return collection.size();
    }
}

A third option that no one has mentioned yet is to put your list size into the model (assuming you are using MVC) as a separate attribute. So in your model you would have "someList" and then "someListSize". That may be simplest way to solve this issue.

There is an extension to the gcc compiler which allows the syntax:

int array[100] = { [0 ... 99] = -1 };

This would set all of the elements to -1.

This is known as "Designated Initializers" see here for further information.

Note this isn't implemented for the gcc c++ compiler.

This seems unnecessary, but VBA is a strange place. If you declare an array variable, then set it using Array() then pass the variable into your function, VBA will be happy.

Sub test()
    Dim fString As String
    Dim arr() As Variant
    arr = Array("foo", "bar")
    fString = processArr(arr)
End Sub

Also your function processArr() could be written as:

Function processArr(arr() As Variant) As String
    processArr = Replace(Join(arr()), " ", "")
End Function

If you are into the whole brevity thing.

A better way, instead of using a conditional like:

if (json.has("club")) {
    String club = json.getString("club"));
 }

is to simply use the existing method optString(), like this:

String club = json.optString("club);

the optString("key") method will return an empty String if the key does not exist and won't, therefore, throw you an exception.

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

I had the same error message but was using psycopg2 to communicate with PostgreSQL. I fixed the permission issues by using the functions copy_from and copy_expert that will open the file on the client side as the user running the python script and feed the data to the database over STDIN.

Refer to this link for further information.

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

For non-object return types, you have to assign the value to the name of your function, like this:

Public Function test() As Integer
    test = 1
End Function

Example usage:

Dim i As Integer
i = test()

If the function returns an Object type, then you must use the Set keyword like this:

Public Function testRange() As Range
    Set testRange = Range("A1")
End Function

Example usage:

Dim r As Range
Set r = testRange()

Note that assigning a return value to the function name does not terminate the execution of your function. If you want to exit the function, then you need to explicitly say Exit Function. For example:

Function test(ByVal justReturnOne As Boolean) As Integer
    If justReturnOne Then
        test = 1
        Exit Function
    End If
    'more code...
    test = 2
End Function

In a simple manner you can also try to just run a pre-packaged docker with intellij, I found the good job of @dlsniper : https://hub.docker.com/r/dlsniper/docker-intellij/

you just need to have docker installed and to run :

docker run -tdi \
       --net="host" \
       --privileged=true \
       -e DISPLAY=${DISPLAY} \
       -v /tmp/.X11-unix:/tmp/.X11-unix \
       -v ${HOME}/.IdeaIC2016.1_docker:/home/developer/.IdeaIC2016.1 \
       -v ${GOPATH}:/home/developer/go \
       dlsniper/docker-intellij

The rule is, if the function that is in the then handler returns a value, the promise resolves/rejects with that value, and if the function returns a promise, what happens is, the next then clause will be the then clause of the promise the function returned, so, in this case, the first example falls through the normal sequence of the thens and prints out values as one might expect, in the second example, the promise object that gets returned when you do Promise.resolve("bbb")'s then is the then that gets invoked when chaining(for all intents and purposes). The way it actually works is described below in more detail.

Quoting from the Promises/A+ spec:

The promise resolution procedure is an abstract operation taking as input a promise and a value, which we denote as [[Resolve]](promise, x). If x is a thenable, it attempts to make promise adopt the state of x, under the assumption that x behaves at least somewhat like a promise. Otherwise, it fulfills promise with the value x.

This treatment of thenables allows promise implementations to interoperate, as long as they expose a Promises/A+-compliant then method. It also allows Promises/A+ implementations to “assimilate” nonconformant implementations with reasonable then methods.

The key thing to notice here is this line:

if x is a promise, adopt its state [3.4]

This should help -

var json = "{'@STARTDATE': '2016-02-17 00:00:00.000',  '@ENDDATE': '2016-02-18 23:59:00.000' }";
var fdate = JObject.Parse(json)["@STARTDATE"];

I think the point is that there is no need to quit the app unless you have buggy software. Android quits the app when the user is not using it and the device needs more memory. If you have an app that needs to run a service in the background, you will likely want a way to turn the service off.

For example, Google Listen continues to play podcast when the app is not visible. But there is always the pause button to turn the podcast off when the user is done with it. If I remember correctly, Listen, even puts a shortcut in the notification bar so you can always get to the pause button quickly. Another example is an app like a twitter app for instance which constantly polls a service on the internet. These types of apps should really allow the user to choose how often to poll the server, or whether even to poll in a background thread.

If you need to have code that runs on exit, you can override onPause(), onStop(), or onDestroy() as appropriate. http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle

You can use JSON.stringify like:

JSON.stringify(new_tweets);

I also had this problem when trying to connect remotely via the Hamachi VPN. I had tried everything available on the internet (including this post) and it still did not work. Note that everything worked fine when the same database was installed on a machine on my local network. Finally I was able to achieve success using the following fix: on the remote machine, enable the IP address on the TCP/IP protocol, like so:

On the remote machine, start SQL Server Configuration Manager, expand SQL Server Network Configuration, select "Protocols for SQLEXPRESS" (or "MSSQLSERVER"), right-click on TCP/IP, on the resulting dialog box go to the IP Addresses tab, and make sure the "IP1" element is Active=Yes and Enabled=Yes. Make note of the IP address (for me it wasn't necessary to modify these). Then stop and start the SQL Server Services. After that, ensure that the firewall on the remote machine is either disabled, or an exception is allowed for port 1433 that includes both the local subnet and the subnet for the address noted in the previous dialog box. On your local machine you should be able to connect by setting the server name to 192.168.1.22\SQLEXPRESS (or [ip address of remote machine]\[SQL server instance name]).

Hope that helps.

Something I did recently, hope it helps. I have a list of dictionaries and wanted to add a value to some existing documents.

for item in my_list:
    my_collection.update({"_id" : item[key] }, {"$set" : {"New_col_name" :item[value]}})

is so easy You can use [phpy - library for php][1] php file

<?php
  require_once "vendor/autoload.php";

  use app\core\App;

  $app = new App();
  $python = $app->python;
  $output = $python->set(your python path)->send(data..)->gen();
  var_dump($ouput);

python file:

import include.library.phpy as phpy
print(phpy.get_data(number of data , first = 1 , two =2 ...))

you can see also example in github page [1]: https://github.com/Raeen123/phpy

You can simply try like this take a string iterate over it using for loop till second last character of string and then simply reverse your loop like following:

public class StringReverse {
    public static void main(String ar[]){
        System.out.println(reverseMe("iniana"));
    }
    static String reverseMe(String s){
       String reverse = "";
       for(int i = s.length()-1; i>=0; i--){
           resverse = reverse + s.charAt(i);
       }
       return reverse;
    }
}

Not a direct answer, but a slight variation to use the "functor" template pattern to hide away the specifics of the lambda type and keeps the code nice and simple.

I was not sure how you wanted to use the decide class so I had to extend the class with a function that uses it. See full example here: https://godbolt.org/z/jtByqE

The basic form of your class might look like this:

template <typename Functor>
class Decide
{
public:
    Decide(Functor dec) : _dec{dec} {}
private:
    Functor _dec;
};

Where you pass the type of the function in as part of the class type used like:

auto decide_fc = [](int x){ return x > 3; };
Decide<decltype(decide_fc)> greaterThanThree{decide_fc};

Again, I was not sure why you are capturing x it made more sense (to me) to have a parameter that you pass in to the lambda) so you can use like:

int result = _dec(5); // or whatever value

See the link for a complete example

• the object which implements Comparable is Fegan.

The method compareTo you are overidding in it should have a Fegan object as a parameter whereas you are casting it to a FoodItems. Your compareTo implementation should describe how a Fegan compare to another Fegan.

• To actually do your sorting, you might want to make your FoodItems implement Comparable aswell and copy paste your actual compareTo logic in it.

heroku logs -t shows us the live logs.

A stack is a LIFO (last in, first out - the last entry you push on to the stack is the first one you get back when you pop) data structure that is typically used to hold stack frames (bits of the stack that belong to the current function).

This includes, but is not limited to:

• the return address.
• a place for a return value.
• passed parameters.
• local variables.

You push items onto the stack and pop them off. In a microprocessor, the stack can be used for both user data (such as local variables and passed parameters) and CPU data (such as return addresses when calling subroutines).

The actual implementation of a stack depends on the microprocessor architecture. It can grow up or down in memory and can move either before or after the push/pop operations.

Operation which typically affect the stack are:

• subroutine calls and returns.
• interrupt calls and returns.
• code explicitly pushing and popping entries.
• direct manipulation of the SP register.

Consider the following program in my (fictional) assembly language:

Addr  Opcodes   Instructions    ; Comments
----  --------  --------------  ----------
                                ; 1: pc<-0000, sp<-8000
0000  01 00 07  load r0,7       ; 2: pc<-0003, r0<-7
0003  02 00     push r0         ; 3: pc<-0005, sp<-7ffe, (sp:7ffe)<-0007
0005  03 00 00  call 000b       ; 4: pc<-000b, sp<-7ffc, (sp:7ffc)<-0008
0008  04 00     pop r0          ; 7: pc<-000a, r0<-(sp:7ffe[0007]), sp<-8000
000a  05        halt            ; 8: pc<-000a
000b  06 01 02  load r1,[sp+2]  ; 5: pc<-000e, r1<-(sp+2:7ffe[0007])
000e  07        ret             ; 6: pc<-(sp:7ffc[0008]), sp<-7ffe

Now let's follow the execution, describing the steps shown in the comments above:

1. This is the starting condition where the program counter is zero and the stack pointer is 8000 (all these numbers are hexadecimal).
2. This simply loads register r0 with the immediate value 7 and moves to the next step (I'll assume that you understand the default behavior will be to move to the next step unless otherwise specified).
3. This pushes r0 onto the stack by reducing the stack pointer by two then storing the value of the register to that location.
4. This calls a subroutine. What would have been the program counter is pushed on to the stack in a similar fashion to r0 in the previous step and then the program counter is set to its new value. This is no different to a user-level push other than the fact it's done more as a system-level thing.
5. This loads r1 from a memory location calculated from the stack pointer - it shows a way to pass parameters to functions.
6. The return statement extracts the value from where the stack pointer points and loads it into the program counter, adjusting the stack pointer up at the same time. This is like a system-level pop (see next step).
7. Popping r0 off the stack involves extracting the value from where the stack pointer points then adjusting that stack pointer up.
8. Halt instruction simply leaves program counter where it is, an infinite loop of sorts.

Hopefully from that description, it will become clear. Bottom line is: a stack is useful for storing state in a LIFO way and this is generally ideal for the way most microprocessors do subroutine calls.

Unless you're a SPARC of course, in which case you use a circular buffer for your stack :-)

Update: Just to clarify the steps taken when pushing and popping values in the above example (whether explicitly or by call/return), see the following examples:

LOAD R0,7
PUSH R0
                     Adjust sp       Store val
sp-> +--------+      +--------+      +--------+
     |  xxxx  |  sp->|  xxxx  |  sp->|  0007  |
     |        |      |        |      |        |
     |        |      |        |      |        |
     |        |      |        |      |        |
     +--------+      +--------+      +--------+

POP R0
                     Get value       Adjust sp
     +--------+      +--------+  sp->+--------+
sp-> |  0007  |  sp->|  0007  |      |  0007  |
     |        |      |        |      |        |
     |        |      |        |      |        |
     |        |      |        |      |        |
     +--------+      +--------+      +--------+

if no error then you will get greatwork as output.

Try it saved my life XD XD

My issue was (as OP suggested) a corrupt .gitignore file. I didn't believe that it was and ignored the possibility until everything else failed. The corruption didn't show up in vi, but there were two bytes on the start of the file that caused the .gitignore file to be ignored. For me, these only showed up when I typed cat .gitignore, which showed:

??# Built application files
*.apk
*.ap_

# ...

I have no idea how these ended up there, but recreating the file fixed the issue. A hex analysis of the corrupt file showed the following:

You should avoid using global vars, and prefer using .data()

So, you'd do:

jQuery('#id').click(function(){
  $(this).data('clicked', true);
});

Then, to check if it was clicked and perform an action:

if(jQuery('#id').data('clicked')) {
    //clicked element, do-some-stuff
} else {
    //run function2
}

Hope this helps. Cheers

I am using Oracle Database and i had same problem. Eventually i found ORACLE DB is converting all the metadata (table/sp/view/trigger) in upper case.

And i was trying how i wrote table name (myTempTable) in sql whereas it expect how it store table name in databsae (MYTEMPTABLE). Also same applicable on column name.

It is quite common problem with developer whoever used sql and now jumped into ORACLE DB.

The problem with the command

sed 'code' file > file

is that file is truncated by the shell before sed actually gets to process it. As a result, you get an empty file.

The sed way to do this is to use -i to edit in place, as other answers suggested. However, this is not always what you want. -i will create a temporary file that will then be used to replace the original file. This is problematic if your original file was a link (the link will be replaced by a regular file). If you need to preserve links, you can use a temporary variable to store the output of sed before writing it back to the file, like this:

tmp=$(sed 'code' file); echo -n "$tmp" > file

Better yet, use printf instead of echo since echo is likely to process \\ as \ in some shells (e.g. dash):

tmp=$(sed 'code' file); printf "%s" "$tmp" > file

I'm a bit behind the times on answering this, but I found a way to do it :)

function eventinfo(id) {
    tr = document.getElementById("ei"+id);
    div = document.getElementById("d"+id);
    if (tr.style.display == "none") {
        tr.style.display="table-row";
        $(div).slideDown('fast');
    } else {
        $(div).slideUp('fast');
        setTimeout(function(){tr.style.display="none";}, 200);
    }
}

I just put a div element inside the table data tags. when it is set visible, as the div expands, the whole row comes down. then tell it to fade back up (then timeout so you see the effect) before hiding the table row again :)

Hope this helps someone!

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

Definition: An imperative language uses a sequence of statements to determine how to reach a certain goal. These statements are said to change the state of the program as each one is executed in turn.

Examples: Java is an imperative language. For example, a program can be created to add a series of numbers:

 int total = 0;
 int number1 = 5;
 int number2 = 10;
 int number3 = 15;
 total = number1 + number2 + number3; 

Each statement changes the state of the program, from assigning values to each variable to the final addition of those values. Using a sequence of five statements the program is explicitly told how to add the numbers 5, 10 and 15 together.

Functional languages: The functional programming paradigm was explicitly created to support a pure functional approach to problem solving. Functional programming is a form of declarative programming.

Advantages of Pure Functions: The primary reason to implement functional transformations as pure functions is that pure functions are composable: that is, self-contained and stateless. These characteristics bring a number of benefits, including the following: Increased readability and maintainability. This is because each function is designed to accomplish a specific task given its arguments. The function does not rely on any external state.

Easier reiterative development. Because the code is easier to refactor, changes to design are often easier to implement. For example, suppose you write a complicated transformation, and then realize that some code is repeated several times in the transformation. If you refactor through a pure method, you can call your pure method at will without worrying about side effects.

Easier testing and debugging. Because pure functions can more easily be tested in isolation, you can write test code that calls the pure function with typical values, valid edge cases, and invalid edge cases.

For OOP People or Imperative languages:

Object-oriented languages are good when you have a fixed set of operations on things and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods and the existing classes are left alone.

Functional languages are good when you have a fixed set of things and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types and the existing functions are left alone.

Cons:

It depends on the user requirements to choose the way of programming, so there is harm only when users don’t choose the proper way.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method
• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

For others that find themselves here, the css I was looking for was

overflow-wrap: break-word;

Which will only break a word if it needs to (the length of the single word is greater than the width of the p), unlike word-break: break-all which can break the last word of every line.

overflow-wrap demo

Result is shown in the following code as column number (8,9 etc.):

Dim lastColumn As Long
lastColumn = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
MsgBox lastColumn

Result is shown in the following code as letter (H,I etc.):

Dim lastColumn As Long
lastColumn = Sheet1.Cells(1, Columns.Count).End(xlToLeft).Column
MsgBox Split(Sheet1.Cells(1, lastColumn).Address, "$")(1)

Ideally we should do it from either controller or directive as per applicable. Use $anchorScroll, $location as dependency injection.

Then call this two method as

$location.hash('scrollToDivID');
$anchorScroll();

Here scrollToDivID is the id where you want to scroll.

Assumed you want to navigate to a error message div as

<div id='scrollToDivID'>Your Error Message</div>

AFAIK, there's no such shorthand for border. You have to define each border separately:

border: 0 solid #000;
border-left: 1px solid #000;
border-right: 1px solid #000;

$scope.rtGo = function(){
            $window.sessionStorage.removeItem('message');
            $window.sessionStorage.removeItem('status');
        }

Answer is to escape the dash!

http://www.mail-archive.com/[email protected]/msg83991.html

private void textBox_KeyDown(object sender, KeyEventArgs e)
{
     if (e.KeyCode == Keys.Enter)
     {
         button.PerformClick();
         // these last two lines will stop the beep sound
         e.SuppressKeyPress = true;
         e.Handled = true;
     }
}

Bind this KeyDown event to the textbox, then when ever you press a key, this event will be fired. Inside the event we check whether user has pressed "Enter key", if so, you can perform you action

Let's say for instance you want to get a list of all your customers:

var customers = context.Customers.ToList();

And let's assume that each Customer object has a reference to its set of Orders, and that each Order has references to LineItems which may also reference a Product.

As you can see, selecting a top-level object with many related entities could result in a query that needs to pull in data from many sources. As a performance measure, Include() allows you to indicate which related entities should be read from the database as part of the same query.

Using the same example, this might bring in all of the related order headers, but none of the other records:

var customersWithOrderDetail = context.Customers.Include("Orders").ToList();

As a final point since you asked for SQL, the first statement without Include() could generate a simple statement:

SELECT * FROM Customers;

The final statement which calls Include("Orders") may look like this:

SELECT *
FROM Customers JOIN Orders ON Customers.Id = Orders.CustomerId;

Just remove the , with replace():

float("123,456.908".replace(',',''))

#include<stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
    // Create a child process     
    int pid = fork();

    if (pid > 0)
    {

            int j=getpid();

            printf("in parent process %d\n",j);
    }
    // Note that pid is 0 in child process
    // and negative if fork() fails
    else if (pid == 0)
    {





            int i=getppid();
            printf("Before sleep %d\n",i);

            sleep(5);
            int k=getppid();

            printf("in child process %d\n",k);
    }

    return 0;

}

As I don't seem to see it already suggested....

const d = new Date();
const day = d.getDate();
const goBack = 3;
for (let i = 0; i < goBack; i++) d.setDate(0);
d.setDate(day);

This will give you the date of today's date 3 months ago as .setDate(0) sets the date to the last day of last month irrespective of how many days a month contains. day is used to restore today's date value.

You want to join on condition 1 AND condition 2, so simply use the AND keyword as below

ON a.userid = b.sourceid AND a.listid = b.destinationid;

Try

https://github.com/fesh0r/fernflower

Download jar from

http://files.minecraftforge.net/maven/net/minecraftforge/fernflower/

Command :

java -jar fernflower.jar -hes=0 -hdc=0 C:\binary  C:\source

Place your jar file in folder C:\binary and source will be extracted and packed in a jar inside C:\source.

Enjoy!

I'm using the following function for that; it's an adaptation from one of the man entries in the fputscsv comments. And you'll probably want to flatten that array; not sure what happens if you pass in a multi-dimensional one.

/**
  * Formats a line (passed as a fields  array) as CSV and returns the CSV as a string.
  * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120
  */
function arrayToCsv( array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = array();
    foreach ( $fields as $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output[] = 'NULL';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
        }
        else {
            $output[] = $field;
        }
    }

    return implode( $delimiter, $output );
}

For proxy_upstream timeout, I tried the above setting but these didn't work.

Setting resolver_timeout worked for me, knowing it was taking 30s to produce the upstream timeout message. E.g. me.atwibble.com could not be resolved (110: Operation timed out).

Look this http://iswift.org/cookbook/compare-2-dates

Get Dates:

// Get current date
let dateA = NSDate()

// Get a later date (after a couple of milliseconds)
let dateB = NSDate()

Using SWITCH Statement

// Compare them
switch dateA.compare(dateB) {
    case .OrderedAscending     :   print("Date A is earlier than date B")
    case .OrderedDescending    :   print("Date A is later than date B")
    case .OrderedSame          :   print("The two dates are the same")
}

using IF Statement

 if dateA.compare(dateB) == .orderedAscending {
     datePickerTo.date = datePicker.date
 }

 //OR

 if case .orderedAcending = dateA.compare(dateB) {

 }

IMHO the best way to do this is using TeleThon, but given that the answer by apadana is outdated beyond repair, I will write the working solution here:

import os
import sys
from telethon import TelegramClient
from telethon.utils import get_display_name

import nest_asyncio
nest_asyncio.apply()

session_name = "<session_name>"
api_id = <api_id>
api_hash = "<api_hash>"
dialog_count = 10 # you may change this

if f"{session_name}.session" in os.listdir():
    os.remove(f"{session_name}.session")

client = TelegramClient(session_name, api_id, api_hash)

async def main():
    dialogs = await client.get_dialogs(dialog_count)
    for dialog in dialogs:
        print(get_display_name(dialog.entity), dialog.entity.id)

async with client:
    client.loop.run_until_complete(main())

this snippet will give you the first 10 chats in your Telegram.

Assumptions:

• you have telethon and nest_asyncio installed
• you have api_id and api_hash from my.telegram.org

I'm writtinga phonegap app, and checkboxes vary in size, look, etc. So I made my own simple checkbox:

First the HTML code:

<span role="checkbox"/>

Then the CSS:

[role=checkbox]{
    background-image: url(../img/checkbox_nc.png);
    height: 15px;
    width: 15px;
    display: inline-block;
    margin: 0 5px 0 5px;
    cursor: pointer;
}

.checked[role=checkbox]{
    background-image: url(../img/checkbox_c.png);
}

To toggle checkbox state, I used JQuery:

CLICKEVENT='touchend';
function createCheckboxes()
{
    $('[role=checkbox]').bind(CLICKEVENT,function()
    {
        $(this).toggleClass('checked');
    });
}

But It can easily be done without it...

Hope it can help!

Make sure you backup your database before trying any of the solutions.

NO, when you are using only one "=" you are assigning the variable.

You must use "==" : You must use "===" :

if (somevar === '836e3ef9-53d4-414b-a401-6eef16ac01d6'){
 $("#code").text(data.DATA[0].ID);
}

You could use fonction like .toLowerCase() to avoid case problem if you want

You can use stepi or nexti (which can be abbreviated to si or ni) to step through your machine code.

As has been mentioned, as of PHP 5.6+ you can (should!) use the ... token (aka "splat operator", part of the variadic functions functionality) to easily call a function with an array of arguments:

<?php
function variadic($arg1, $arg2)
{
    // Do stuff
    echo $arg1.' '.$arg2;
}

$array = ['Hello', 'World'];

// 'Splat' the $array in the function call
variadic(...$array);

// 'Hello World'

Note: array items are mapped to arguments by their position in the array, not their keys.

As per CarlosCarucce's comment, this form of argument unpacking is the fastest method by far in all cases. In some comparisons, it's over 5x faster than call_user_func_array.

Aside

Because I think this is really useful (though not directly related to the question): you can type-hint the splat operator parameter in your function definition to make sure all of the passed values match a specific type.

(Just remember that doing this it MUST be the last parameter you define and that it bundles all parameters passed to the function into the array.)

This is great for making sure an array contains items of a specific type:

<?php

// Define the function...

function variadic($var, SomeClass ...$items)
{
    // $items will be an array of objects of type `SomeClass`
}

// Then you can call...

variadic('Hello', new SomeClass, new SomeClass);

// or even splat both ways

$items = [
    new SomeClass,
    new SomeClass,
];

variadic('Hello', ...$items);

If you have already installed app on your device, try to change bundle identifer on the web .plist (not app plist) with something else like "com.vistair.docunet-test2", after that refresh webpage and try to reinstall... It works for me

Create a folder named images located in the path you are planning to place the php script you are about to create. Make sure it has write rights for everybody or the scripts won't work ( it won't be able to upload the files into the directory).

public Class ClassName{
    public int PropName{get;set;}
    public ClassName{
        PropName=0;  //Default Value
    }
}

Another possible reason for this error for the Mega 2560 is if your code has three exclamation marks in a row. Perhaps in a recently added string.

3 bang marks in a row causes the Mega 2560 bootloader to go into Monitor mode from which it can not finish programming.

"!!!" <--- breaks Mega 2560 bootloader.

To fix, unplug the Arduino USB to reset the COM port and then recompile with only two exclamation points or with spaces between or whatever. Then reconnect the Arduino and program as usual.

Yes, this bit me yesterday and today I tracked down the culprit. Here is a link with more information: http://forum.arduino.cc/index.php?topic=132595.0

As Anton Gogolev noted, FileStream reads 4096 bytes at a time by default, But you can specify any other value using the FileStream constructor:

new FileStream(file, FileMode.Open, FileAccess.Read, FileShare.ReadWrite, 16 * 1024 * 1024)

Note that Brad Abrams from Microsoft wrote in 2004:

there is zero benefit from wrapping a BufferedStream around a FileStream. We copied BufferedStream’s buffering logic into FileStream about 4 years ago to encourage better default performance

I had this:

 class Util {
  static boolean isNeverAsync = System.getenv().get("asyncc_exclude_redundancy").equals("yes");
}

you can probably see the problem, the env var might return null instead of string. So just to test my theory, I changed it to:

 class Util {
  static boolean isNeverAsync = false;
}

and the problem went away. Too bad that Java can't give you the exact stack trace of the error though, kinda weird.

I'm not 100% sure whether this is a solution, but I turned off Bluetooth and it stopped saying :

EDIT (removed wrong solution). EDIT (to add this other option):

Another way to use it would be subclass QThread since it has protected *sleep methods.

QThread::usleep(unsigned long microseconds);
QThread::msleep(unsigned long milliseconds);
QThread::sleep(unsigned long second);

Here's the code to create your own *sleep method.

#include <QThread>    

class Sleeper : public QThread
{
public:
    static void usleep(unsigned long usecs){QThread::usleep(usecs);}
    static void msleep(unsigned long msecs){QThread::msleep(msecs);}
    static void sleep(unsigned long secs){QThread::sleep(secs);}
};

and you call it by doing this:

Sleeper::usleep(10);
Sleeper::msleep(10);
Sleeper::sleep(10);

This would give you a delay of 10 microseconds, 10 milliseconds or 10 seconds, accordingly. If the underlying operating system timers support the resolution.

There some kind of old school 'Marxismic' way to the cast int -> bool without C4800 warnings of Microsoft's cl compiler - is to use negation of negation.

int  i  = 0;
bool bi = !!i;

int  j  = 1;
bool bj = !!j;

I was facing same error, But I didn't need to change my password.

Just go to bitbucket->preferences->accounts select your account and check if your password is correct.

I was able to get the most recent media of a user using the following API without authentication (including the description, likes, comments count).

https://www.instagram.com/apple/?__a=1

E.g.

https://www.instagram.com/{username}/?__a=1

Instead of that, you should use ViewModel, which will retain the data until the activity life cycle.

Set column max width using:

pd.set_option('max_colwidth', 800)

This particular statement sets max width to 800px, per column.

Swift 4 You cannot compare Any to nil.Because an optional can be nil and hence it always succeeds to true. The only way is to cast it to your desired object and compare it to nil.

if (someone as? String) != nil
{
   //your code`enter code here`
}

There is really nothing you can do to completely prevent this. Scrapers can fake their user agent, use multiple IP addresses, etc. and appear as a normal user. The only thing you can do is make the text not available at the time the page is loaded - make it with image, flash, or load it with JavaScript. However, the first two are bad ideas, and the last one would be an accessibility issue if JavaScript is not enabled for some of your regular users.

If they are absolutely slamming your site and rifling through all of your pages, you could do some kind of rate limiting.

There is some hope though. Scrapers rely on your site's data being in a consistent format. If you could randomize it somehow it could break their scraper. Things like changing the ID or class names of page elements on each load, etc. But that is a lot of work to do and I'm not sure if it's worth it. And even then, they could probably get around it with enough dedication.

Consider also series between:

df = df[df['closing_price'].between(99, 101)]

Since upgrading my typings to react 0.14.43 (I'm not sure exactly when this was introduced), the React.FormEvent type is now generic and this removes the need for a cast.

import React = require('react');

interface ITestState {
    selectedValue: string;
}

export class Test extends React.Component<{}, ITestState> {

    constructor() {
        super();
        this.state = { selectedValue: "A" };
    }

    change(event: React.FormEvent<HTMLSelectElement>) {
        // No longer need to cast to any - hooray for react!
        var safeSearchTypeValue: string = event.currentTarget.value;

        console.log(safeSearchTypeValue); // in chrome => B

        this.setState({
            selectedValue: safeSearchTypeValue
        });
    }

    render() {
        return (
            <div>
                <label htmlFor="searchType">Safe</label>
                <select className="form-control" id="searchType" onChange={ e => this.change(e) } value={ this.state.selectedValue }>
                    <option value="A">A</option>
                    <option value="B">B</option>
                </select>
                <h1>{this.state.selectedValue}</h1>
            </div>
        );
    }
}

The selected answer is absolutely correct, however it did not leave me with the latest commit/pushes ...

So for me:

git reset --hard dev/jobmanager-tools
git pull  ( did not work as git was not sure what branch i wanted)

Since I know I want to temporarily set my upstream branch for a few weeks to a specific branch ( same as the one i switched to / checked out earlier and did a hard reset on )

So AFTER reset
