File file = new File("C:/aaa/bbb/ccc/ddd/test.java");
File curentPath = new File(file.getParent());
//get current path "C:/aaa/bbb/ccc/ddd/"
String currentFolder= currentPath.getName().toString();
//get name of file to string "ddd"

if you need to append folder "ddd" by another path use;

String currentFolder= "/" + currentPath.getName().toString();

I found a simple way to do this on EightForums (Option 8), create a string value under HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers. Set the name to the path to the program and the value to ~RUNASDMIN. Next time you open the program it will open as an administrator

[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
    "C:\\Program Files (x86)\\Microsoft Visual Studio 12.0\\Common7\\IDE\\devenv.exe"="~RUNASADMIN"

You can try this:

for file in *.jpg;
do
  mv $file $somestring_${file:((-7))}
done

You can see "parameter expansion" in man bash to understand the above better.

I modified Neutrino's solution to make the xaml look less verbose when specifying the value:

Sorry for no pictures of the rendered xaml, just imagine a [=] hamburger button that you click and it turns into [<-] a back button and also toggles the visibility of a Grid.

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

...

<Grid>
    <Button x:Name="optionsButton">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Visible" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Hamburger Width="10" Height="10" />
    </Button>

    <Button x:Name="optionsBackButton" Visibility="Collapsed">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Collapsed" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Back Width="12" Height="11" />
    </Button>
</Grid>

...

<Grid Grid.RowSpan="2" x:Name="optionsPanel" Visibility="Collapsed">

</Grid>

You can also specify values this way like in Neutrino's solution:

<Button x:Name="optionsButton">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <local:SetterAction PropertyName="Visibility" Value="{x:Static Visibility.Collapsed}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="{x:Static Visibility.Visible}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="{x:Static Visibility.Visible}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>

    <glyphs:Hamburger Width="10" Height="10" />
</Button>

Use a timer. Keep in mind that .NET comes with a number of different timers. This article covers the differences.

Yes that is valid syntax but it may well not do what you want.

Execution will continue after your RAISERROR except if you add a RETURN. So you will need to add a block with BEGIN ... END to hold the two statements.

Also I'm not sure why you plumped for severity 15. That usually indicates a syntax error.

Finally I'd simplify the conditions using IN

CREATE PROCEDURE [dbo].[AddApplicationUser] (@TenantId BIGINT,
                                            @UserType TINYINT,
                                            @UserName NVARCHAR(100),
                                            @Password NVARCHAR(100))
AS
  BEGIN
      IF ( @TenantId IS NULL
           AND @UserType IN ( 0, 1 ) )
        BEGIN
            RAISERROR('The value for @TenantID should not be null',15,1);

            RETURN;
        END
  END

I typically perform the validation on the client side:

<asp:checkbox id="chkTerms" text=" I agree to the terms" ValidationGroup="vg" runat="Server"  />
<asp:CustomValidator id="vTerms"
                ClientValidationFunction="validateTerms" 
                ErrorMessage="<br/>Terms and Conditions are required."

                ValidationGroup="vg"
                runat="server"/>

<asp:Button ID="btnSubmit" OnClick="btnSubmit_Click" CausesValidation="true" Text="Submit" ValidationGroup="vg" runat="server" />

<script>
    function validateTerms(source, arguments) {
        var $c = $('#<%= chkTerms.ClientID %>');
        if($c.prop("checked")){
            arguments.IsValid = true;
        } else {

Convert Dictionary to Data Frame

col_dict_df = pd.Series(col_dict).to_frame('new_col').reset_index()

Give new name to Column

col_dict_df.columns = ['col1', 'col2']

I just used post and an if:

data = getDataObjectByForm(form);
var jqxhr = $.post(url, data, function(){}, 'json')
    .done(function (response) {
        if (response instanceof Object)
            var json = response;
        else
            var json = $.parseJSON(response);
        // console.log(response);
        // console.log(json);
        jsonToDom(json);
        if (json.reload != undefined && json.reload)
            location.reload();
        $("body").delay(1000).css("cursor", "default");
    })
    .fail(function (jqxhr, textStatus, error) {
        var err = textStatus + ", " + error;
        console.log("Request Failed: " + err);
        alert("Fehler!");
    });

mkdirs() also creates parent directories in the path this File represents.

javadocs for mkdirs():

Creates the directory named by this abstract pathname, including any necessary but nonexistent parent directories. Note that if this operation fails it may have succeeded in creating some of the necessary parent directories.

javadocs for mkdir():

Creates the directory named by this abstract pathname.

Example:

File  f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());

will yield false for the first [and no dir will be created], and true for the second, and you will have created non_existing_dir/someDir

For O(1) random access, which can not be beaten.

It should be that the particular mvn command execs and does not return, thereby not executing the rest of the commands.

The Data Export function in MySQL Workbench allows 2 of the 3 ways. There's a checkbox Skip Table Data (no-data) on the export page which allows to either dump with or without data. Just dumping the data without meta data is not supported.

switch(position) {
  case 0:
    ...
    break;
  case 1:
    ...
    break;
  default:
    ...

}

Did you mean that?

I had similar requirement of running a LAMP stack, Mongo DB and my own services

Docker is OS based virtualisation, which is why it isolates its container around a running process, hence it requires least one process running in FOREGROUND.

So you provide your own startup script as the entry point, thus your startup script becomes an extended Docker image script, in which you can stack any number of the services as far as AT LEAST ONE FOREGROUND SERVICE IS STARTED, WHICH TOO TOWARDS THE END

So my Docker image file has two line below in the very end:

COPY myStartupScript.sh /usr/local/myscripts/myStartupScript.sh
CMD ["/bin/bash", "/usr/local/myscripts/myStartupScript.sh"]

In my script I run all MySQL, MongoDB, Tomcat etc. In the end I run my Apache as a foreground thread.

source /etc/apache2/envvars
/usr/sbin/apache2 -DFOREGROUND

This enables me to start all my services and keep the container alive with the last service started being in the foreground

Hope it helps

UPDATE: Since I last answered this question, new things have come up like Docker compose, which can help you run each service on its own container, yet bind all of them together as dependencies among those services, try knowing more about docker-compose and use it, it is more elegant way unless your need does not match with it.

If this is just a one-off exercise, as an easier alternative, you could apply filters to your source data, and then copy and paste the filtered rows into your new worksheet?

Shared Preferences are the key/value pairs that we can store. They are internal type of storage which means we do not have to create an external database to store it. To see it go to, 1) Go to View in the menu bar. Select Tool Windows. 2) Click on Device File Explorer. 3) Device File Explorer opens up in the right hand side. 4) Find the data folder and click on it. 5) In the data folder, you can select another data folder. 6) Try to search for your package name in this data folder. Ex: com.example.com 7) Then Click on shared_prefs and open the .xml file.

Hope this helps!

No. PDO queries are not prepared on the client side. PDO simply sends the SQL query and the parameters to the database server. The database is what does the substitution (of the ?'s). You have two options:

• Use your DB's logging function (but even then it's normally shown as two separate statements (ie, "not final") at least with Postgres)
• Output the SQL query and the paramaters and piece it together yourself

Can you consider using Nix http://nixos.org/nix/ ?

Nix supports multi-user package management: multiple users can share a common Nix store securely, don’t need to have root privileges to install software, and can install and use different versions of a package.

When you have two or more (in the example below there're three) elements in the string, then you can use comma to separate these items:

date, time, event_name = ev.get_text(separator='@').split("@")

After this line of code, the three variables will have values from three parts of the variable ev

So, if the variable ev contains this string and we apply separator '@':

Sa., 23. März@19:00@Klavier + Orchester: SPEZIAL

Then, after split operation the variable

• date will have value "Sa., 23. März"
• time will have value "19:00"
• event_name will have value "Klavier + Orchester: SPEZIAL"

The bug is probably somewhere else in your code, because it should work fine:

>>> 3 not in [2, 3, 4]
False
>>> 3 not in [4, 5, 6]
True

Or with tuples:

>>> (2, 3) not in [(2, 3), (5, 6), (9, 1)]
False
>>> (2, 3) not in [(2, 7), (7, 3), "hi"]
True

I think this is the kind of question only a core developer could/should answer. I've researched and found the core ticket #17048: URLs delivered to the browser should be root-relative. Where we can find the reasons explained by Andrew Nacin, lead core developer. He also links to this [wp-hackers] thread. On both those links, these are the key quotes on why WP doesn't use relative URLs:

Core ticket:

• Root-relative URLs aren't really proper. /path/ might not be WordPress, it might be outside of the install. So really it's not much different than an absolute URL.

• Any relative URLs also make it significantly more difficult to perform transformations when the install is moved. The find-replace is going to be necessary in most situations, and having an absolute URL is ironically more portable for those reasons.

• absolute URLs are needed in numerous other places. Needing to add these in conditionally will add to processing, as well as introduce potential bugs (and incompatibilities with plugins).

[wp-hackers] thread

• Relative to what, I'm not sure, as WordPress is often in a subdirectory, which means we'll always need to process the content to then add in the rest of the path. This introduces overhead.

• Keep in mind that there are two types of relative URLs, with and without the leading slash. Both have caveats that make this impossible to properly implement.

• WordPress should (and does) store absolute URLs. This requires no pre-processing of content, no overhead, no ambiguity. If you need to relocate, it is a global find-replace in the database.

And, on a personal note, more than once I've found theme and plugins bad coded that simply break when WP_CONTENT_URL is defined.
They don't know this can be set and assume that this is true: WP.URL/wp-content/WhatEver, and it's not always the case. And something will break along the way.

The plugin Relative URLs (linked in edse's Answer), applies the function wp_make_link_relative in a series of filters in the action hook template_redirect. It's quite a simple code and seems a nice option.

From fragment to activty:

((YourActivityClassName)getActivity()).yourPublicMethod();

From activity to fragment:

FragmentManager fm = getSupportFragmentManager();

//if you added fragment via layout xml
YourFragmentClass fragment = 
(YourFragmentClass)fm.findFragmentById(R.id.your_fragment_id);
fragment.yourPublicMethod();

If you added fragment via code and used a tag string when you added your fragment, use findFragmentByTag instead:

YourFragmentClass fragment = (YourFragmentClass)fm.findFragmentByTag("yourTag");

Try http://php.net/manual/en/curl.examples-basic.php :)

<?php

$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

$output = curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

As the documentation says:

The basic idea behind the cURL functions is that you initialize a cURL session using the curl_init(), then you can set all your options for the transfer via the curl_setopt(), then you can execute the session with the curl_exec() and then you finish off your session using the curl_close().

The #/ trick works, but adds a history event to the browser. So, clicking back doesn't work as the user may want/expect it to.

$('body').click('a[href="#"]', function(e) {e.preventDefault() }); is the way I went, as it works for already existing content, and any elements added to the DOM after load.

Specifically, I needed to do this in a bootstrap dropdown-menu inside of a .btn-group(Reference), so I did:

$('body').click('.dropdown-menu li a[href="#"]', function(e) {e.preventDefault() });

This way it was targeted, and didn't affect anything thing else on the page.

You need to use a hashbang. Add it to the first line of your python script.

#! <full path of python interpreter>

Then change the file permissions, and add the executing permission.

chmod +x <filename>

And finally execute it using

./<filename>

If its in the current directory,

If you are trying to install it on a windows machine you need to have a 64-bit version of python 3.5. This is the only way to actually install it. From the website:

TensorFlow supports only 64-bit Python 3.5 on Windows. We have tested the pip packages with the following distributions of Python:

Python 3.5 from Anaconda

Python 3.5 from python.org.

You can download the proper version of python from here (make sure you grab one of the ones that says "Windows x86-64")

You should now be able to install with pip install tensorflow or python -m pip install tensorflow (make sure that you are using the right pip, from python3, if you have both python2 and python3 installed)

Remember to install Anaconda 3-5.2.0 as the latest version which is 3-5.3.0 have python version 3.7 which is not supported by Tensorflow.

placeholders= ', '.join("'{"+str(i)+"}'" for i in range(len(l)))
query="select name from students where id (%s)"%placeholders
query=query.format(*l)
cursor.execute(query)

This should solve your problem.

I had this problem today using any of concat, append or merge, and I got around it by adding a helper column sequentially numbered and then doing an outer join

helper=1
for i in df1.index:
    df1.loc[i,'helper']=helper
    helper=helper+1
for i in df2.index:
    df2.loc[i,'helper']=helper
    helper=helper+1
df1.merge(df2,on='helper',how='outer')

In your comment in response to John, you suggest that you want the keys and values of the dictionary, not just the values.

PEP 256 suggests this for sorting a dictionary by values.

import operator
sorted(d.iteritems(), key=operator.itemgetter(1))

If you want descending order, do this

sorted(d.iteritems(), key=itemgetter(1), reverse=True)

1st way is to use props

<Row id = "someRandomID">

Wherein, in the Definition, you may just go

const Row = props  => {
 div id = {props.id}
}

The same could be done with class, replacing id with className in the above example.

You might as well use react-html-id, that is an npm package. This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.

Ref: react-html-id

Peace.

Embed code example:

<object type="application/pdf" data="example.pdf" width="100%" height="100%" id="examplePDF" name="examplePDF"><param name='src' value='example.pdf'/></object>

<script>
   examplePDF.printWithDialog();
</script>

May have to fool around with the ids/names. Using adobe reader...

You can do so in Firefox and Safari (Chrome also?)

::selection { background: transparent; }
::-moz-selection { background: transparent; }

Throwing runtime exceptions "sparingly" isn't really a good policy -- Effective Java recommends that you use checked exceptions when the caller can reasonably be expected to recover. (Programmer error is a specific example: if a particular case indicates programmer error, then you should throw an unchecked exception; you want the programmer to have a stack trace of where the logic problem occurred, not to try to handle it yourself.)

If there's no hope of recovery, then feel free to use unchecked exceptions; there's no point in catching them, so that's perfectly fine.

It's not 100% clear from your example which case this example is in your code, though.

//Just in one line custom function
function cmp($a, $b)
{
return (float) $a['price'] < (float)$b['price'];
}
@uasort($inventory, "cmp");
print_r($inventory);

//result

Array
(
[2] => Array
    (
        [type] => pork
        [price] => 5.43
    )

[0] => Array
    (
        [type] => fruit
        [price] => 3.5
    )

[1] => Array
    (
        [type] => milk
        [price] => 2.9
    )

)

'&' --> '&'

'<' --> '&lt;'

'>' --> '&gt;'

if you use Sql Server

delete from Table where id between 79 and 296

After your edit : you now clarified that you want :

ID (>79 AND < 296)

So use this :

delete from Table where id > 79 and id < 296

This below function worked.

 private createDownloadableCsvFile(fileName, content) {
   let link = document.createElement("a");
   link.download = fileName;
   link.href = `data:application/octet-stream,${content}`;
   return link;
 }

If you have a hash structure like this:

Parameters: {"link"=>{"title"=>"Something", "time_span"=>[{"start"=>"2017-05-06T16:00:00.000Z", "end"=>"2017-05-06T17:00:00.000Z"}]}}

Then this is how I got it to work:

params.require(:link).permit(:title, time_span: [[:start, :end]])

You could create a function that parses argument with sed;

atouch() {
  mkdir -p $(sed 's/\(.*\)\/.*/\1/' <<< $1) && touch $1
}

and then, execute it with one argument:

atouch B/C/D/myfile.txt

Use inet_ntop() and inet_pton() if you need it other way around. Do not use inet_ntoa(), inet_aton() and similar as they are deprecated and don't support ipv6.

Here is a nice guide with quite a few examples.

// IPv4 demo of inet_ntop() and inet_pton()

struct sockaddr_in sa;
char str[INET_ADDRSTRLEN];

// store this IP address in sa:
inet_pton(AF_INET, "192.0.2.33", &(sa.sin_addr));

inet_ntop(AF_INET, &(sa.sin_addr), str, INET_ADDRSTRLEN);

printf("%s\n", str); // prints "192.0.2.33"

1. Create a Cocoa Touch class.

2. Insert the code in RoundButton class.

   import UIKit
   
   @IBDesignable
   class RoundButton: UIButton {
   
       @IBInspectable var cornerRadius: CGFloat = 0{
           didSet{
           self.layer.cornerRadius = cornerRadius
           }
       }
   
       @IBInspectable var borderWidth: CGFloat = 0{
           didSet{
               self.layer.borderWidth = borderWidth
           }
       }
   
       @IBInspectable var borderColor: UIColor = UIColor.clear{
           didSet{
               self.layer.borderColor = borderColor.cgColor
           }
       }
   }
   

3. Refer the image.

a bit change in format

format : "DD/MM/YYYY"

Try this

$('#testID').addClass('nameOfClass');

or

$('#testID').removeClass('nameOfClass');

It would look like this:

public static final String WELCOME_MESSAGE = "Hello, welcome to the server";

If the constants are for use just in a single class, you'd want to make them private instead of public.

your sql Statement creating code may be like

statement = connection.createStatement();

To solve "com.microsoft.sqlserver.jdbc.SQLServerException: The requested operation is not supported on forward only result sets" exception change above code with

statement = connection.createStatement(
    ResultSet.TYPE_SCROLL_INSENSITIVE, 
    ResultSet.CONCUR_READ_ONLY);

After above change you can use

int size = 0;
try {
    resultSet.last();
    size = resultSet.getRow();
    resultSet.beforeFirst();
}
catch(Exception ex) {
    return 0;
}
return size;

to get row count

This should work with only one loop:

function checkIfArrayIsUnique(arr) {
    var map = {}, i, size;

    for (i = 0, size = arr.length; i < size; i++){
        if (map[arr[i]]){
            return false;
        }

        map[arr[i]] = true;
    }

    return true;
}

    <select name="career" id="career" onchange="location = this.value;">
        <option value="resume" selected> All Applications </option>
        <option value="resume&j=14">Seo Expert</option>
        <option value="resume&j=21">Project Manager</option>
        <option value="resume&j=33">Php Developer</option>
    </select>

You have to use Javascript Filereader for this. (Introduction into filereader-api: http://www.html5rocks.com/en/tutorials/file/dndfiles/)

Once the user have choose a image you can read the file-path of the chosen image and place it into your html.

Example:

<form id="form1" runat="server">
    <input type='file' id="imgInp" />
    <img id="blah" src="#" alt="your image" />
</form>

Javascript:

function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }
}

$("#imgInp").change(function(){
    readURL(this);
});

Just another approach:

string mystr = "hello";
MessageBox.show(mystr.Substring(0, 1));

Use the partial argument of sort(). For the second highest value:

n <- length(x)
sort(x,partial=n-1)[n-1]

There could be a mistake in @JARH's answer in the case of a multivariable regression. (I do not have enough reputation to comment.)

In the following line:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-1))) for i in ts_b],

the t-values follows a chi-squared distribution of degree len(newX)-1 instead of following a chi-squared distribution of degree len(newX)-len(newX.columns)-1.

So this should be:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-len(newX.columns)-1))) for i in ts_b]

(See t-values for OLS regression for more details)

I don't think you understand how \n works. The resulting string still just contains a byte with value 10. This is represented in javascript source code with \n.

The code snippet you posted doesn't actually work, but if it did, the newline would be equivalent to \n, unless it's a windows-style newline, in which case it would be \r\n. (but even that the replace would still work).

table {
 border-spacing: 10px 0px;
}

.rightborder {
border-right: 1px solid #fff;
}

Then with your code you can:

<td class="rightborder">whatever</td>

Hope that helps!

I'm also interested in this problem.

As @Thasmo mentioned, port forwardings can be specified ONLY with docker run (and docker create) command.
Other commands, docker start does not have -p option and docker port only displays current forwardings.

To add port forwardings, I always follow these steps,

1. stop running container

   docker stop test01
   

2. commit the container

   docker commit test01 test02
   

   NOTE: The above, test02 is a new image that I'm constructing from the test01 container.

3. re-run from the commited image

   docker run -p 8080:8080 -td test02
   

Where the first 8080 is the local port and the second 8080 is the container port.

Sadly there are no operation-assignment operators in VBA.

(Addition-assignment += are available in VB.Net)

Pointless workaround;

Sub Inc(ByRef i As Integer)
   i = i + 1  
End Sub
...
Static value As Integer
inc value
inc value

Here's one that most POSIX compatible shells support:

join_by() {
    # Usage:  join_by "||" a b c d
    local arg arr=() sep="$1"
    shift
    for arg in "$@"; do
        if [ 0 -lt "${#arr[@]}" ]; then
            arr+=("${sep}")
        fi
        arr+=("${arg}") || break
    done
    printf "%s" "${arr[@]}"
}

Instead of making a touchable UIImageView then placing it on the navbar, you should just create a UIBarButtonItem, which you make out of a UIImageView.

First make the image view:

UIImageView *yourImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"nameOfYourImage.png"]];

Then make the barbutton item out of your image view:

UIBarButtonItem *yourBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:yourImageView];

Then add the bar button item to your navigation bar:

self.navigationItem.rightBarButtonItem = yourBarButtonItem;

Remember that this code goes into the view controller which is inside a navigation controller viewcontroller array. So basically, this "touchable image-looking bar button item" will only appear in the navigation bar when this view controller when it's being shown. When you push another view controller, this navigation bar button item will disappear.

None of the above worked for me. (substitution on \r, ^M, ctrl-v-ctrl-m ) I used copy and paste to paste my text into a new file.

If you have macros that interfere, you can try :set paste before the paste operation and :set nopaste after.

One way without using external process forking is string manipulation, in a generic case it would look like this:

#start value
CNT=1

for [whatever iterative loop, seq, cat, find...];do
   # number of 0s is at least the amount of decimals needed, simple concatenation
   TEMP="000000$CNT"
   # for example 6 digits zero padded, get the last 6 character of the string
   echo ${TEMP:(-6)}
   # increment, if the for loop doesn't provide the number directly
   TEMP=$(( TEMP + 1 ))
done

This works quite well on WSL as well, where forking is a really heavy operation. I had a 110000 files list, using printf "%06d" $NUM took over 1 minute, the solution above ran in about 1 second.

You can use html5 tag to download the image directly

<?php
$file = "Bang.png"; //Let say If I put the file name Bang.png
echo "<a href='download.php?nama=".$file."' download>donload</a> ";
?>

The change event is triggered on the <select> element, not the <option> element. However, that's not the only problem. The way you defined the change function won't cause a rerender of the component. It seems like you might not have fully grasped the concept of React yet, so maybe "Thinking in React" helps.

You have to store the selected value as state and update the state when the value changes. Updating the state will trigger a rerender of the component.

var MySelect = React.createClass({
     getInitialState: function() {
         return {
             value: 'select'
         }
     },
     change: function(event){
         this.setState({value: event.target.value});
     },
     render: function(){
        return(
           <div>
               <select id="lang" onChange={this.change} value={this.state.value}>
                  <option value="select">Select</option>
                  <option value="Java">Java</option>
                  <option value="C++">C++</option>
               </select>
               <p></p>
               <p>{this.state.value}</p>
           </div>
        );
     }
});

React.render(<MySelect />, document.body);

Also note that <p> elements don't have a value attribute. React/JSX simply replicates the well-known HTML syntax, it doesn't introduce custom attributes (with the exception of key and ref). If you want the selected value to be the content of the <p> element then simply put inside of it, like you would do with any static content.

                    public boolean verify(String arg0, SSLSession arg1) {
                            return true;

For those who are using xampp:

"php.validate.executablePath": "C:\\xampp\\php\\php.exe",

You must use Rect.width() and Rect.Height() which returned from getTextBounds() instead. That works for me.

Be explicit - then the compiler won't warn that you perhaps made a mistake.

while ( (list = list->next) != NULL )

or

while ( (list = list->next) )

Some day you'll be glad the compiler told you, people do make that mistake ;)

Assuming your current remote is named origin then:

Delete the current remote reference with

git remote rm origin

Add the new remote

git remote add origin <URL to new heroku app>

push to new domain

git push -u origin master

The -u will set this up as tracked.

Using a subshell substitution to parse the words undoes all the work you are doing to put spaces together.

Try instead:

cat CSV_file | sed -n 1'p' | tr ',' '\n' | while read word; do
    echo $word
done

That also increases parallelism. Using a subshell as in your question forces the entire subshell process to finish before you can start iterating over the answers. Piping to a subshell (as in my answer) lets them work in parallel. This matters only if you have many lines in the file, of course.

In my case the file is a shell script (*.sh file) meant to deploy our project to a local development server, for my developers.

The shell script should work consistently and may be updated; so I tracked it in the same Git project as the code which the script is meant to deploy.

The shell script runs one executable, and then allows that executable to run; so the script is still running; so my shell still has the script open; so it's locked.

I Ctrl+C'd to kill the script (so now my local dev server is no longer accessible), now I can checkout freely.

On Python 3 you can use the itertools islice to slice the dict.items() iterator

import itertools

d = {1: 2, 3: 4, 5: 6}

dict(itertools.islice(d.items(), 2))

{1: 2, 3: 4}

Note: this solution does not take into account specific keys. It slices by internal ordering of d, which in Python 3.7+ is guaranteed to be insertion-ordered.

I had the same problem. I solve it when I convert string to factor. In your case, check the class of variable and check if they are numeric and 'train and test' should be factor.

FYI: I also noticed I can mess up a perfectly working spring boot app and prevent it from serving contents from the static folder, if I add a bad rest controller like so

 @RestController
public class BadController {
    @RequestMapping(method= RequestMethod.POST)
    public String someMethod(@RequestParam(value="date", required=false)String dateString, Model model){
        return "foo";
    }
}

In this example, after adding the bad controller to the project, when the browser asks for a file available in static folder, the error response is '405 Method Not Allowed'.

Notice paths are not mapped in the bad controller example.

After upgrading lots of packages (Spyder 3 to 4, Keras and Tensorflow and lots of their dependencies), I had the same problem today! I cannot figure out what happened; but the (conda-based) virtual environment that kept using Spyder 3 did not have the problem. Although installing tkinter or changing the backend, via matplotlib.use('TkAgg) as shown above, or this nice post on how to change the backend, might well resolve the problem, I don't see these as rigid solutions. For me, uninstalling matplotlib and reinstalling it was magic and the problem was solved.

pip uninstall matplotlib

... then, install

pip install matplotlib

From all the above, this could be a package management problem, and BTW, I use both conda and pip, whenever feasible.

Needs ensure library but you can compare list by:

ensure([1, 2]).contains_only([2, 1])

This will not raise assert exception. Documentation of thin is really thin so i would recommend to look at ensure's codes on github

What I usually do is supply the path to the executable explicitly:

EXE=./bin/
...
test all:
    $(EXE)x

I also use this technique to run non-native binaries under an emulator like QEMU if I'm cross compiling:

EXE = qemu-mips ./bin/

If make is using the sh shell, this should work:

test all:
    PATH=bin:$PATH x

2019 Update for Bootstrap 4

Now that Bootstrap 4 uses SASS, you can easily change the primary button color using the button-variant mixins:

$mynewcolor:#77cccc;

.btn-primary {
    @include button-variant($mynewcolor, darken($mynewcolor, 7.5%), darken($mynewcolor, 10%), lighten($mynewcolor,5%), lighten($mynewcolor, 10%), darken($mynewcolor,30%));
}
    
.btn-outline-primary {
    @include button-outline-variant($mynewcolor, #222222, lighten($mynewcolor,5%), $mynewcolor);
}

https://codeply.com/go/2bHYxYSC0n (SASS demo)

This SASS compiles into the following CSS...

.btn-primary {
    color: #212529;
    background-color: #7cc;
    border-color: #5bc2c2
}

.btn-primary:hover {
    color: #212529;
    background-color: #52bebe;
    border-color: #8ad3d3
}

.btn-primary:focus,
.btn-primary.focus {
    box-shadow: 0 0 0 .2rem rgba(91, 194, 194, 0.5)
}

.btn-primary.disabled,
.btn-primary:disabled {
    color: #212529;
    background-color: #7cc;
    border-color: #5bc2c2
}

.btn-primary:not(:disabled):not(.disabled):active,
.btn-primary:not(:disabled):not(.disabled).active,
.show>.btn-primary.dropdown-toggle {
    color: #212529;

}

.btn-outline-primary {
    color: #7cc;
    background-color: transparent;
    background-image: none;
    border-color: #7cc
}

.btn-outline-primary:hover {

    box-shadow: 0 0 0 .2rem rgba(119, 204, 204, 0.5)
}

    color: #7cc;
    background-color: transparent
}

.btn-outline-primary:not(:disabled):not(.disabled):active,
.btn-outline-primary:not(:disabled):not(.disabled).active,
.show>.btn-outline-primary.dropdown-toggle {

    border-color: #7cc
}

Very simple :

In your Super POM parent or setting.xml, use

        <repository>
        <id>central</id>
        <releases>
            <updatePolicy>never</updatePolicy>
        </releases>
        <snapshots>
            <updatePolicy>never</updatePolicy>
        </snapshots>
        <url>http://repo1.maven.org/maven2</url>
        <layout>legacy</layout>
    </repository>

It's my tips

You could do

echo current(explode(' ',$myvalue));

If you are using Maven, run this command in your project directory

mvn clean package

Try this: getActivity().runOnUiThread(new Runnable...

It's because:

1) the implicit this in your call to runOnUiThread is referring to AsyncTask, not your fragment.

2) Fragment doesn't have runOnUiThread.

However, Activity does.

Note that Activity just executes the Runnable if you're already on the main thread, otherwise it uses a Handler. You can implement a Handler in your fragment if you don't want to worry about the context of this, it's actually very easy:

// A class instance
private Handler mHandler = new Handler(Looper.getMainLooper());

// anywhere else in your code
mHandler.post(<your runnable>);
// ^ this will always be run on the next run loop on the main thread.

EDIT: @rciovati is right, you are in onPostExecute, that's already on the main thread.

You can escape it by preceding it with a \ (making it \/), or you could use new RegExp('/') to avoid escaping the regex.

See example in JSFiddle.

'/'.match(/\//)            // matches /
'/'.match(new RegExp('/')  // matches /

Do a clean. product > clean . Terminal purge & reboot didn't work for me, cleaning did.

I have found the selected answer to have problems with upscaling, and so I have made (yet) another version (which I have tested):

public static Point scaleFit(Point src, Point bounds) {
  int newWidth = src.x;
  int newHeight = src.y;
  double boundsAspectRatio = bounds.y / (double) bounds.x;
  double srcAspectRatio = src.y / (double) src.x;

  // first check if we need to scale width
  if (boundsAspectRatio < srcAspectRatio) {
    // scale width to fit
    newWidth = bounds.x;
    //scale height to maintain aspect ratio
    newHeight = (newWidth * src.y) / src.x;
  } else {
    //scale height to fit instead
    newHeight = bounds.y;
    //scale width to maintain aspect ratio
    newWidth = (newHeight * src.x) / src.y;
  }

  return new Point(newWidth, newHeight);
}

Written in Android terminology :-)

as for the tests:

@Test public void scaleFit() throws Exception {
  final Point displaySize = new Point(1080, 1920);
  assertEquals(displaySize, Util.scaleFit(displaySize, displaySize));
  assertEquals(displaySize, Util.scaleFit(new Point(displaySize.x / 2, displaySize.y / 2), displaySize));
  assertEquals(displaySize, Util.scaleFit(new Point(displaySize.x * 2, displaySize.y * 2), displaySize));
  assertEquals(new Point(displaySize.x, displaySize.y * 2), Util.scaleFit(new Point(displaySize.x / 2, displaySize.y), displaySize));
  assertEquals(new Point(displaySize.x * 2, displaySize.y), Util.scaleFit(new Point(displaySize.x, displaySize.y / 2), displaySize));
  assertEquals(new Point(displaySize.x, displaySize.y * 3 / 2), Util.scaleFit(new Point(displaySize.x / 3, displaySize.y / 2), displaySize));
}

If you set the recovery mode on the database in 2005 (don't know for pre-2005) it will drop the log file all together and then you can put it back in full recovery mode to restart/recreate the logfile. We ran into this with SQL 2005 express in that we couldn't get near the 4GB limit with data until we changed the recovery mode.

I find them useful when I have a class that encapsulates a lot of memory. For example in a recent game I've been working on I have an influence map class that contains a collection of very large arrays of contiguous memory. I want that all allocated at startup, all freed at shutdown and I definitely want only one copy of it. I also have to access it from many places. I find the singleton pattern to be very useful in this case.

I'm sure there are other solutions but I find this one very useful and easy to implement.

+ (NSArray *)getArrayListFromDictionary:(NSDictionary *)dictMain paramName:(NSString *)paramName
{
    if([dictMain isKindOfClass:[NSDictionary class]])
    {
        if ([dictMain objectForKey:paramName])
        {
            if ([[dictMain objectForKey:paramName] isKindOfClass:[NSArray class]])
            {
                NSArray *dataArray = [dictMain objectForKey:paramName];

                return dataArray;
            }
        }
    }
    return [[NSArray alloc] init];
}

Hope this helps!

It's too late, however the best example, how to add pseudo element in jQuery style

 $(document).ready(function(){_x000D_
 $("a.dummy").css({"background":"#003d79","color":"#fff","padding": "5px 10px","border-radius": "3px","text-decoration":"none"});_x000D_
 $("a.dummy").hover(function() {_x000D_
            $(this).css("background-color","#0670c9")_x000D_
          }).mouseout(function(){_x000D_
              $(this).css({"background-color":"#003d79",});_x000D_
          });_x000D_
 _x000D_
 });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>_x000D_
<a class="dummy" href="javascript:void()">Just Link</a>

This is the best help that I found:

https://atom.io/packages/atom-beautify

This package can be installed in Atom and then CTRL+ALT+B solve the problem.

If you want to pack a struct with a value <255 (one byte unsigned, uint8_t) and end up with a string of one character, you're probably looking for the format B instead of c. C converts a character to a string (not too useful by itself) while B converts an integer.

struct.pack('B', 65)

(And yes, 65 is \x41, not \x65.)

The struct class will also conveniently handle endianness for communication or other uses.

You don't detect whether the user has javascript disabled (server side or client). Instead, you assume that javascript is disabled and build your webpage with javascript disabled. This obviates the need for noscript, which you should avoid using anyway because it doesn't work quite right and is unnecessary.

For example, just build your site to say <div id="nojs">This website doesn't work without JS</div>

Then, your script will simply do document.getElementById('nojs').style.display = 'none'; and go about its normal JS business.

Using the MaximumSize and MinimumSize properties of the form will fix the form size, and prevent the user from resizing the form, while keeping the form default FormBorderStyle.

this.MaximumSize = new Size(XX, YY);
this.MinimumSize = new Size(X, Y);

You can read the post request parameter with jQuery-PostCapture(@ssut/jQuery-PostCapture).

PostCapture plugin is consisted of some tricks.

When you are click the submit button, the onsubmit event will be dispatched.

At the time, PostCapture will be serialize form data and save to html5 localStorage(if available) or cookie storage.

I have one more solution to do this

    document.querySelector("footer").innerHTML = data;
  });

I think you mean to update it back to the OLD password, when the NEW one is not supplied.

DROP TRIGGER IF EXISTS upd_user;

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '') THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

However, this means a user can never blank out a password.

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '' OR NEW.password = OLD.password) THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

The difference is not just for Chrome but for most of the web browsers.

F5 refreshes the web page and often reloads the same page from the cached contents of the web browser. However, reloading from cache every time is not guaranteed and it also depends upon the cache expiry.

Shift + F5 forces the web browser to ignore its cached contents and retrieve a fresh copy of the web page into the browser.

Shift + F5 guarantees loading of latest contents of the web page.
However, depending upon the size of page, it is usually slower than F5.

You may want to refer to: What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?

I really didn't want to type \n every single time and @matthause's answer didn't seem to work for me, so I created my own class

class File():

    def __init__(self, name, mode='w'):
        self.f = open(name, mode, buffering=1)
        
    def write(self, string, newline=True):
        if newline:
            self.f.write(string + '\n')
        else:
            self.f.write(string)

And here it is implemented

f = File('console.log')

f.write('This is on the first line')
f.write('This is on the second line', newline=False)
f.write('This is still on the second line')
f.write('This is on the third line')

This should show in the log file as

This is on the first line
This is on the second lineThis is still on the second line
This is on the third line

#include <stdio.h>
#include <stdlib.h>

// ....


system("my_bash_script.sh");

You can also use something like

<c:if test="${ testObject.testPropert == "testValue" }">...</c:if>

All you need to do is use getCheckedRadioButtonId() and isChecked() method,

if(gender.getCheckedRadioButtonId()==-1)
{
    Toast.makeText(getApplicationContext(), "Please select Gender", Toast.LENGTH_SHORT).show();
}
else
{
    // get selected radio button from radioGroup
    int selectedId = gender.getCheckedRadioButtonId();
    // find the radiobutton by returned id
    selectedRadioButton = (RadioButton)findViewById(selectedId);
    Toast.makeText(getApplicationContext(), selectedRadioButton.getText().toString()+" is selected", Toast.LENGTH_SHORT).show();
}

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

I solved is by using android:background instead of app:srcCompact.

This is caused by xmlns:app="http://schemas.android.com/apk/res-auto". As people have suggested above, you could use /lib-auto or /lib/your-package but I got suspicious namespace error when I tried using /lib-auto and unexpected namespace prefix error with /lib/my-package .

Running the following commands solved this for me 1. python manage.py migrate 2. python manage.py makemigrations 3. python manage.py makemigrations appName

Extend LinearLayout/RelativeLayout and use it straight on the XML

When you've written something that isn't allowed by the language standard (and therefore can't really be well-defined behaviour, which is reason enough to not do it) but happens to map to some kind of executable if fed naïvely to the compiling engine, then -fpermissive will do just that instead of stopping with this error message. In some cases, the program will then behave exactly as you originally intended, but you definitely shouldn't rely on it unless you have some very special reason not to use some other solution.

On Linux/Unix, you can append files to the .gitignore file with the echo command. For example if you want to ignore all .svn folders, run this from the root of the project:

echo .svn/ >> .gitignore

I believe the simplest thing to do is:

#assuming three sets
set1 = {1,2,3,4,5}
set2 = {2,3,8,9}
set3 = {2,10,11,12}

#intersection
set4 = set1 & set2 & set3

set4 will be the intersection of set1 , set2, set3 and will contain the value 2.

print(set4)

set([2])

Depending on your needs, here are a couple of ways:

IF EXISTS (SELECT * FROM TABLE WHERE COLUMN = 'SOME VALUE')
    --INSERT SOMETHING
ELSE
    --INSERT SOMETHING ELSE

Or a bit longer

DECLARE @retVal int

SELECT @retVal = COUNT(*) 
FROM TABLE
WHERE COLUMN = 'Some Value'

IF (@retVal > 0)
BEGIN
    --INSERT SOMETHING
END
ELSE
BEGIN
    --INSERT SOMETHING ELSE
END 

An even simpler solution to the above:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <color android:color="@color/semitransparent_white" />
    </item>
    <item>
        <color android:color="@color/transparent" />
    </item>
</selector>

Save that in the drawable folder and you're good to go.

using ArrayList also you can try like this

ArrayList arraylist = ... // myobject data list

ArrayList temp = (ArrayList)arraylist.Clone();

foreach (var item in temp)
{
      if (...)
         arraylist.Remove(item);
}

dict(zip(*numpy.unique(y, return_counts=True)))

Just copied Seppo Enarvi's comment here which deserves to be a proper answer

Variation of sudo write:

into .vimrc

cmap w!! w !sudo tee % >/dev/null

After reload vim you can do "sudo save" as

:w!!

Nicely explained above!

For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the % with a !

So:

SET TEXT=Hello World
SET SUBSTRING=!TEXT:~3,5!
ECHO !SUBSTRING!

Just for the record, here is the difference between If and IIf:

IIf(condition, true-part, false-part):

• This is the old VB6/VBA Function
• The function always returns an Object type, so if you want to use the methods or properties of the chosen object, you have to re-cast it with DirectCast or CType or the Convert.* Functions to its original type
• Because of this, if true-part and false-part are of different types there is no matter, the result is just an object anyway

If(condition, true-part, false-part):

• This is the new VB.NET Function
• The result type is the type of the chosen part, true-part or false-part
• This doesn't work, if Strict Mode is switched on and the two parts are of different types. In Strict Mode they have to be of the same type, otherwise you will get an Exception
• If you really need to have two parts of different types, switch off Strict Mode (or use IIf)
• I didn't try so far if Strict Mode allows objects of different type but inherited from the same base or implementing the same Interface. The Microsoft documentation isn't quite helpful about this issue. Maybe somebody here knows it.

The app object is instantiated on creation of the Express server. It has a middleware stack that can be customized in app.configure()(this is now deprecated in version 4.x).

To setup your middleware, you can invoke app.use(<specific_middleware_layer_here>) for every middleware layer that you want to add (it can be generic to all paths, or triggered only on specific path(s) your server handles), and it will add onto your Express middleware stack. Middleware layers can be added one by one in multiple invocations of use, or even all at once in series with one invocation. See use documentation for more details.

To give an example for conceptual understanding of Express Middleware, here is what my app middleware stack (app.stack) looks like when logging my app object to the console as JSON:

stack: 
   [ { route: '', handle: [Function] },
     { route: '', handle: [Function: static] },
     { route: '', handle: [Function: bodyParser] },
     { route: '', handle: [Function: cookieParser] },
     { route: '', handle: [Function: session] },
     { route: '', handle: [Function: methodOverride] },
     { route: '', handle: [Function] },
     { route: '', handle: [Function] } ]

As you might be able to deduce, I called app.use(express.bodyParser()), app.use(express.cookieParser()), etc, which added these express middleware 'layers' to the middleware stack. Notice that the routes are blank, meaning that when I added those middleware layers I specified that they be triggered on any route. If I added a custom middleware layer that only triggered on the path /user/:id that would be reflected as a string in the route field of that middleware layer object in the stack printout above.

Each layer is essentially adding a function that specifically handles something to your flow through the middleware.

E.g. by adding bodyParser, you're ensuring your server handles incoming requests through the express middleware. So, now parsing the body of incoming requests is part of the procedure that your middleware takes when handling incoming requests -- all because you called app.use(bodyParser).

The Ookii VistaFolderBrowserDialog is the one you want.

If you only want the Folder Browser from Ooki Dialogs and nothing else then download the Source, cherry-pick the files you need for the Folder browser (hint: 7 files) and it builds fine in .NET 4.5.2. I had to add a reference to System.Drawing. Compare the references in the original project to yours.

How do you figure out which files? Open your app and Ookii in different Visual Studio instances. Add VistaFolderBrowserDialog.cs to your app and keep adding files until the build errors go away. You find the dependencies in the Ookii project - Control-Click the one you want to follow back to its source (pun intended).

Here are the files you need if you're too lazy to do that ...

NativeMethods.cs
SafeHandles.cs
VistaFolderBrowserDialog.cs
\ Interop
   COMGuids.cs
   ErrorHelper.cs
   ShellComInterfaces.cs
   ShellWrapperDefinitions.cs

Edit line 197 in VistaFolderBrowserDialog.cs unless you want to include their Resources.Resx

throw new InvalidOperationException(Properties.Resources.FolderBrowserDialogNoRootFolder);

throw new InvalidOperationException("Unable to retrieve the root folder.");

Add their copyright notice to your app as per their license.txt

The code in \Ookii.Dialogs.Wpf.Sample\MainWindow.xaml.cs line 160-169 is an example you can use but you will need to remove this, from MessageBox.Show(this, for WPF.

Incase someone is still trying to figure this out. This is how you get the center X and Y of the view.

    int pos[] = new int[2];
    view.getLocationOnScreen(pos);
    int centerX = pos[0] + view.getMeasuredWidth() / 2;
    int centerY = pos[1] + view.getMeasuredHeight() / 2;

Yes, this is an old question. But it's misleading, as this was the first result in my search, and both the answers aren't correct anymore.

You can change your Github account name at any time.

To do this, click your profile picture > Settings > Account Settings > Change Username.

Links to your repositories will redirect to the new URLs, but they should be updated on other sites because someone who chooses your abandoned username can override the links. Links to your profile page will be 404'd.

For more information, see the official help page.

And furthermore, if you want to change your username to something else, but that specific username is being taken up by someone else who has been completely inactive for the entire time their account has existed, you can report their account for name squatting.

The hexadecimal value you are looking for is %2B

To get it automatically in PHP run your string through urlencode($stringVal). And then run it rhough urldecode($stringVal) to get it back.

If you want the JavaScript to handle it, use escape( str )

Edit

After @bobince's comment I did more reading and he is correct. Use encodeURIComponent(str) and decodeURIComponent(str). Escape will not convert the characters, only escape them with \'s

It selects all elements where the class name contains the string "span" somewhere. There's also ^= for the beginning of a string, and $= for the end of a string. Here's a good reference for some CSS selectors.

I'm only familiar with the bootstrap classes spanX where X is an integer, but if there were other selectors that ended in span, it would also fall under these rules.

It just helps to apply blanket CSS rules.

Modules go in site-packages and executables go in your system's executable path. For your environment, this path is /usr/local/bin/.

To avoid having to deal with this, simply use easy_install, distribute or pip. These tools know which files need to go where.

Use This:-

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

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

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

Your solution is correct, but your outer loop is still longer than needed. You don't need to compare the last element with anything else because it's been already compared with all the others in the previous iterations. Your inner loop still prevents that, but since we're talking about collision detection you can save the unnecessary check.

Using the same language you used to illustrate your algorithm, you'd come with something like this:

for (int i = 0, i < mylist.size() - 1; ++i)
    for (int j = i + 1, j < mylist.size(); --j)
        compare(mylist[i], mylist[j])

This code will help you.

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] 
initWithTarget:self action:@selector(showHideNavbar:)];
[self.view addGestureRecognizer:tapGesture];

-(void) showHideNavbar:(id) sender 
{ 
// write code to show/hide nav bar here 
// check if the Navigation Bar is shown
if (self.navigationController.navigationBar.hidden == NO)
{
// hide the Navigation Bar
[self.navigationController setNavigationBarHidden:YES animated:YES];
}
// if Navigation Bar is already hidden
else if (self.navigationController.navigationBar.hidden == YES)
{
// Show the Navigation Bar
[self.navigationController setNavigationBarHidden:NO animated:YES];
}
}

The only way I've managed to do this is by using overflow: visible; and width: 20000px; on the parent element. There is no way to do this with CSS level 1 that I'm aware of and I refused to think I'd have to go all gung-ho with CSS level 3. The example below has 18 menus that extend beyond my 1920x1200 resolution LCD, if your screen is larger just duplicate the first tier menu elements or just resize the browser. Alternatively and with slightly lower levels of browser compatibility you could use CSS3 media queries.

Use bind_rows() from the dplyr package:

bind_rows(list_of_dataframes, .id = "column_label")

You can try to get locale from system resources:

PackageManager packageManager = context.getPackageManager();
Resources resources = packageManager.getResourcesForApplication("android");
String language = resources.getConfiguration().locale.getLanguage();

Here is how to do dump the database (with just the schema):

mysqldump -u root -p"passwd" --no-data --add-drop-database --databases my_db_name | sed 's#/[*]!40000 DROP DATABASE IF EXISTS my_db_name;#' >my_db_name.sql

If you also want the data, remove the --no-data option.

Following Glens idea, here it goes another possibility. It would allow you to scroll inside the div, but would prevent the body to scroll with it, when the div scroll ends. However, it seems to accumulate too many preventDefault if you scroll too much, and then it creates a lag if you want to scroll up. Does anybody have a suggestion to fix that?

    $(".scrollInsideThisDiv").bind("mouseover",function(){
       var bodyTop = document.body.scrollTop;
       $('body').on({
           'mousewheel': function(e) {
           if (document.body.scrollTop == bodyTop) return;
           e.preventDefault();
           e.stopPropagation();
           }
       });
    });
    $(".scrollInsideThisDiv").bind("mouseleave",function(){
          $('body').unbind("mousewheel");
    });

Like "Whisk" Said, the trick is in "AppendDataBoundItems" property

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        DropDownList1.AppendDataBoundItems = true;
        DropDownList1.Items.Insert(0, new ListItem(String.Empty, String.Empty));
        DropDownList1.SelectedIndex = 0;
    }
}

Thanks "Whisk"

If you are using Bootstrap 4, and you don't want to change your markup:

var $myGroup = $('#myGroup');
$myGroup.on('show.bs.collapse','.collapse', function() {
$myGroup.find('.collapse.show').collapse('hide');
});

first select the table you you would like to make the relation with >> then go to operation , for each table there is difference operation setting, >> inside operation "storage engine" choose innoDB option

innoDB will allow you to view the "relation view" which will help you make the foreign key

If you get some compile errors for example:

private void methodThatRequiresAPI11() {
        BitmapFactory.Options options = new BitmapFactory.Options();
                options.inPreferredConfig = Config.ARGB_8888;  // API Level 1          
                options.inSampleSize = 8;    // API Level 1
                options.inBitmap = bitmap;   // **API Level 11**
        //...
    }

You get compile error:

Field requires API level 11 (current min is 10): android.graphics.BitmapFactory$Options#inBitmap

Since version 17 of Android Development Tools (ADT) there is one new and very useful annotation @TargetApi that can fix this very easily. Add it before the method that is enclosing the problematic declaration:

@TargetApi
private void methodThatRequiresAPI11() {            
  BitmapFactory.Options options = new BitmapFactory.Options();
      options.inPreferredConfig = Config.ARGB_8888;  // API Level 1          
      options.inSampleSize = 8;    // API Level 1

      // This will avoid exception NoSuchFieldError (or NoSuchMethodError) at runtime. 
      if (Integer.valueOf(android.os.Build.VERSION.SDK) >= android.os.Build.VERSION_CODES.HONEYCOMB) {
        options.inBitmap = bitmap;   // **API Level 11**
            //...
      }
    }

No compile errors now and it will run !

EDIT: This will result in runtime error on API level lower than 11. On 11 or higher it will run without problems. So you must be sure you call this method on an execution path guarded by version check. TargetApi just allows you to compile it but you run it on your own risk.

In order to include the number of row index "columns" in your total shape I would personally add together the number of columns df.columns.size with the attribute pd.Index.nlevels/pd.MultiIndex.nlevels:

Set up dummy data

import pandas as pd

flat_index = pd.Index([0, 1, 2])
multi_index = pd.MultiIndex.from_tuples([("a", 1), ("a", 2), ("b", 1), names=["letter", "id"])

columns = ["cat", "dog", "fish"]

data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
flat_df = pd.DataFrame(data, index=flat_index, columns=columns)
multi_df = pd.DataFrame(data, index=multi_index, columns=columns)

# Show data
# -----------------
# 3 columns, 4 including the index
print(flat_df)
    cat  dog  fish
id                
0     1    2     3
1     4    5     6
2     7    8     9

# -----------------
# 3 columns, 5 including the index
print(multi_df)
           cat  dog  fish
letter id                
a      1     1    2     3
       2     4    5     6
b      1     7    8     9

Writing our process as a function:

def total_ncols(df, include_index=False):
    ncols = df.columns.size
    if include_index is True:
        ncols += df.index.nlevels
    return ncols

print("Ignore the index:")
print(total_ncols(flat_df), total_ncols(multi_df))

print("Include the index:")
print(total_ncols(flat_df, include_index=True), total_ncols(multi_df, include_index=True))

This prints:

Ignore the index:
3 3

Include the index:
4 5

If you want to only include the number of indices if the index is a pd.MultiIndex, then you can throw in an isinstance check in the defined function.

As an alternative, you could use df.reset_index().columns.size to achieve the same result, but this won't be as performant since we're temporarily inserting new columns into the index and making a new index before getting the number of columns.

Every process running under the Linux kernel receives its own, unique environment that it inherits from its parent. In this case, the parent will be either a shell itself (spawning a sub shell), or the 'login' program (on a typical system).

As each process' environment is protected, there is no way to 'inject' an environmental variable to every running process, so even if you modify the default shell .rc / profile, it won't go into effect until each process exits and reloads its start up settings.

Look in /etc/ to modify the default start up variables for any particular shell. Just realize that users can (and often do) change them in their individual settings.

Unix is designed to obey the user, within limits.

NB: Bash is not the only shell on your system. Pay careful attention to what the /bin/sh symbolic link actually points to. On many systems, this could actually be dash which is (by default, with no special invocation) POSIXLY correct. Therefore, you should take care to modify both defaults, or scripts that start with /bin/sh will not inherit your global defaults. Similarly, take care to avoid syntax that only bash understands when editing both, aka avoiding bashisms.

The size_t type is the type returned by the sizeof operator. It is an unsigned integer capable of expressing the size in bytes of any memory range supported on the host machine. It is (typically) related to ptrdiff_t in that ptrdiff_t is a signed integer value such that sizeof(ptrdiff_t) and sizeof(size_t) are equal.

When writing C code you should always use size_t whenever dealing with memory ranges.

The int type on the other hand is basically defined as the size of the (signed) integer value that the host machine can use to most efficiently perform integer arithmetic. For example, on many older PC type computers the value sizeof(size_t) would be 4 (bytes) but sizeof(int) would be 2 (byte). 16 bit arithmetic was faster than 32 bit arithmetic, though the CPU could handle a (logical) memory space of up to 4 GiB.

Use the int type only when you care about efficiency as its actual precision depends strongly on both compiler options and machine architecture. In particular the C standard specifies the following invariants: sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) placing no other limitations on the actual representation of the precision available to the programmer for each of these primitive types.

Note: This is NOT the same as in Java (which actually specifies the bit precision for each of the types 'char', 'byte', 'short', 'int' and 'long').

http://sfml-dev.org/documentation/2.0/classsf_1_1Music.php

SFML does not have mp3 support as another has suggested. What I always do is use Audacity and make all my music into ogg, and leave all my sound effects as wav.

Loading and playing a wav is simple (crude example):

http://www.sfml-dev.org/tutorials/2.0/audio-sounds.php

#include <SFML/Audio.hpp>
...
sf::SoundBuffer buffer;
if (!buffer.loadFromFile("sound.wav")){
    return -1;
}
sf::Sound sound;
sound.setBuffer(buffer);
sound.play();

Streaming an ogg music file is also simple:

#include <SFML/Audio.hpp>
...
sf::Music music;
if (!music.openFromFile("music.ogg"))
    return -1; // error
music.play();

Just use the following sql, you are done:

SELECT replace(CustomerName,' ', '') FROM Customers;

you can test this sample over here: W3School

When your Android stuio/jre uses a differ version of java, you will receive this error. to solve it, just set Android studio/jre to your JAVA_HOME. and uninstall your own java.

If you're checking for explicit types, why are you declaring those variables as T's?

T HowToCast<T>(T t)
{
    if (typeof(T) == typeof(string))
    {
        var newT1 = "some text";
        var newT2 = t;  //this builds but I'm not sure what it does under the hood.
        var newT3 = t.ToString();  //for sure the string you want.
    }

    return t;
}

Init your autowired component in @PostConstruct method

@Component
public class TestClass {
   private static AutowiredTypeComponent component;

   @Autowired
   private AutowiredTypeComponent autowiredComponent;

   @PostConstruct
   private void init() {
      component = this.autowiredComponent;
   }

   public static void testMethod() {
      component.callTestMethod();
   }
}

The approach you're looking for is FillDown. Another way so you don't have to kick your head off every time is to store formulas in an array of strings. Combining them gives you a powerful method of inputting formulas by the multitude. Code follows:

Sub FillDown()

    Dim strFormulas(1 To 3) As Variant

    With ThisWorkbook.Sheets("Sheet1")
        strFormulas(1) = "=SUM(A2:B2)"
        strFormulas(2) = "=PRODUCT(A2:B2)"
        strFormulas(3) = "=A2/B2"

        .Range("C2:E2").Formula = strFormulas
        .Range("C2:E11").FillDown
    End With

End Sub

Screenshots:

Result as of line: .Range("C2:E2").Formula = strFormulas:

Result as of line: .Range("C2:E11").FillDown:

Of course, you can make it dynamic by storing the last row into a variable and turning it to something like .Range("C2:E" & LRow).FillDown, much like what you did.

Hope this helps!

You might try using a library like redux-saga. It allows for a very clean way to sequence async functions, fire off actions, use delays and more. It is very powerful!

Use this both installation and then go ahead with your python code

pip install google-cloud    
pip install google-cloud-vision

Take a look at the InstallHelper method of the ManagedInstaller class. You can install a service using:

string[] args;
ManagedInstallerClass.InstallHelper(args);

This is exactly what InstallUtil does. The arguments are the same as for InstallUtil.

The benefits of this method are that it involves no messing in the registry, and it uses the same mechanism as InstallUtil.

This is how I've tackled a similar issue in an ES6 context:

function merge(array1, array2, prop) {
    return array2.map(function (item2) {
        var item1 = array1.find(function (item1) {
            return item1[prop] === item2[prop];
        });
        return Object.assign({}, item1, item2);
    });
}

Note: This approach will not return any items from array1 that don't appear in array2.

EDIT: I have some scenarios where I want to preserve items that don't appear in the second array so I came up with another method.

function mergeArrays(arrays, prop) {
    const merged = {};

    arrays.forEach(arr => {
        arr.forEach(item => {
            merged[item[prop]] = Object.assign({}, merged[item[prop]], item);
        });
    });

    return Object.values(merged);
}

var arr1 = [
    { name: 'Bob', age: 11 },
    { name: 'Ben', age: 12 },
    { name: 'Bill', age: 13 },
];

var arr2 = [
    { name: 'Bob', age: 22 },
    { name: 'Fred', age: 24 },
    { name: 'Jack', age: 25 },
    { name: 'Ben' },
];

console.log(mergeArrays([arr1, arr2], 'name'));

I doubt the standard library supports this.

But you can use the google maps utility library:

http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries#MarkerWithLabel

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);

var myOptions = {
    zoom: 8,
    center: myLatlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };

map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);

var marker = new MarkerWithLabel({
   position: myLatlng,
   map: map,
   draggable: true,
   raiseOnDrag: true,
   labelContent: "A",
   labelAnchor: new google.maps.Point(3, 30),
   labelClass: "labels", // the CSS class for the label
   labelInBackground: false
 });

The basics about marker can be found here: https://developers.google.com/maps/documentation/javascript/overlays#Markers

For removing document, I prefer using Model.remove(conditions, [callback])

Please refer API documentation for remove :-

http://mongoosejs.com/docs/api.html#model_Model.remove

For this case, code will be:-

FBFriendModel.remove({ id : 333 }, function(err, callback){
console.log(‘Do Stuff’);
})

If you want to remove documents without waiting for a response from MongoDB, do not pass a callback, then you need to call exec on the returned Query

var removeQuery = FBFriendModel.remove({id : 333 });
removeQuery.exec();

An argument is an instantiation of a parameter.

To remove the left-most word, you'll need to use either RIGHT or SUBSTRING. Assuming you know how many characters are involved, that would look either of the following:

SELECT RIGHT('Hello World', 5)
SELECT SUBSTRING('Hello World', 6, 100)

If you don't know how many characters that first word has, you'll need to find out using CHARINDEX, then substitute that value back into SUBSTRING:

SELECT SUBSTRING('Hello World', CHARINDEX(' ', 'Hello World') + 1, 100)

This finds the position of the first space, then takes the remaining characters to the right.

Normally views are not parameterized. But you could always inject some parameters. For example using session context:

CREATE VIEW my_view
AS
SELECT *
FROM tab
WHERE num = SESSION_CONTEXT(N'my_num');

Invocation:

EXEC sp_set_session_context 'my_num', 1; 
SELECT * FROM my_view;

And another:

EXEC sp_set_session_context 'my_num', 2; 
SELECT * FROM my_view;

DBFiddle Demo

The same is applicable for Oracle (of course syntax for context function is different).

Executing Linq queries can generate extra threads. When I try to execute code that uses Linq query collection in the immediate window it often refuses to run because not enough threads are available to the debugger.

As others have said, for threads to exit when they are finished is perfectly normal.

In Python 3.8+ you can do

import hashlib
with open("your_filename.txt", "rb") as f:
    file_hash = hashlib.md5()
    while chunk := f.read(8192):
        file_hash.update(chunk)

print(file_hash.digest())
print(file_hash.hexdigest())  # to get a printable str instead of bytes

Consider using hashlib.blake2b instead of md5 (just replace md5 with blake2b in the above snippet). It's cryptographically secure and faster than MD5.

Another way to write it shortly

bePlanVar = !!((bePlanVar == false));

// is equivalent to

bePlanVar = (bePlanVar == false) ? true : false;

// and 

if (bePlanVar == false) {
    bePlanVar = true;
} else {
    bePlanVar = false;
}

Use the cgwin command SPLIT. Samples

To split a file every 500 lines counts:

split -l 500 [filename.ext]

by default, it adds xa,xb,xc... to filename after extension

To generate files with numbers and ending in correct extension, use following

split -l 1000 sourcefilename.ext destinationfilename -d --additional-suffix=.ext

the position of -d or -l does not matter,

• "-d" is same as --numeric-suffixes
• "-l" is same as --lines

For more: split --help

I really don't like the fact that, because of the "promise" way of doing things, the consumer of the service that uses $http has to "know" about how to unpack the response.

I just want to call something and get the data out, similar to the old $scope.items = Data.getData(); way, which is now deprecated.

I tried for a while and didn't come up with a perfect solution, but here's my best shot (Plunker). It may be useful to someone.

app.factory('myService', function($http) {
  var _data;  // cache data rather than promise
  var myService = {};

  myService.getData = function(obj) { 
    if(!_data) {
      $http.get('test.json').then(function(result){
        _data = result.data;
        console.log(_data);  // prove that it executes once
        angular.extend(obj, _data);
      }); 
    } else {  
      angular.extend(obj, _data);
    }
  };

  return myService;
}); 

Then controller:

app.controller('MainCtrl', function( myService,$scope) {
  $scope.clearData = function() {
    $scope.data = Object.create(null);
  };
  $scope.getData = function() {
    $scope.clearData();  // also important: need to prepare input to getData as an object
    myService.getData($scope.data); // **important bit** pass in object you want to augment
  };
});

Flaws I can already spot are

• You have to pass in the object which you want the data added to, which isn't an intuitive or common pattern in Angular
• getData can only accept the obj parameter in the form of an object (although it could also accept an array), which won't be a problem for many applications, but it's a sore limitation
• You have to prepare the input object $scope.data with = {} to make it an object (essentially what $scope.clearData() does above), or = [] for an array, or it won't work (we're already having to assume something about what data is coming). I tried to do this preparation step IN getData, but no luck.

Nevertheless, it provides a pattern which removes controller "promise unwrap" boilerplate, and might be useful in cases when you want to use certain data obtained from $http in more than one place while keeping it DRY.

Try this: (source: http://just-another-blog.net/programming/powershell-and-the-net-framework/)

If you want buffers to work like tabs, check out the tabline plugin.

That uses a single window, and adds a line on the top to simulate the tabs (just showing the list of buffers). This came out a long time ago when tabs were only supported in GVim but not in the command line vim. Since it is only operating with buffers, everything integrates well with the rest of vim.

neither fgets nor getchar works to solve the problem. the only workaround is keeping a space before %c while using scanf scanf(" %c",ch); // will only work

In the follwing fgets also not work..

char line[256];
char ch;
int i;

printf("Enter a num : ");
scanf("%d",&i);
printf("Enter a char : ");

if (fgets(line, sizeof line, stdin) == NULL) {
    printf("Input error.\n");
    exit(1);
}

ch = line[0];
printf("Character read: %c\n", ch);

If you try appending the number like, say listName.append(4) , this will append 4 at last. But if you are trying to take <int> and then append it as, num = 4 followed by listName.append(num), this will give you an error as 'num' is of <int> type and listName is of type <list>. So do type cast int(num) before appending it.

Primary key attributes are just as updateable as any other attributes of a table. Stability is often a desirable property of a key but definitely not an absolute requirement. If it makes sense from a business perpective to update a key then there's no fundamental reason why you shouldn't.

HTMLInputElement.setSelectionRange( selectionStart, selectionEnd );

// References
var e = document.getElementById( "helloworldinput" );

// Move caret to beginning on focus
e.addEventListener( "focus", function( event )
{
    // References
    var e = event.target;

    // Action
    e.setSelectionRange( 0, 0 );            // Doesn’t work for focus event
    
    window.setTimeout( function()
    {
        e.setSelectionRange( 0, 0 );        // Works
        //e.setSelectionRange( 1, 1 );      // Move caret to second position
        //e.setSelectionRange( 1, 2 );      // Select second character

    }, 0 );

}, false );

I copy and change a part of your code as the below:

from pandas import read_csv, DataFrame
from sklearn import tree
from sklearn.tree import DecisionTreeClassifier
from os import system

data = read_csv('D:/training.csv')
Y = data.Y
X = data.ix[:,"X0":"X33"]

dtree = tree.DecisionTreeClassifier(criterion = "entropy")
dtree = dtree.fit(X, Y)

After making sure you have dtree, which means that the above code runs well, you add the below code to visualize decision tree:

Remember to install graphviz first: pip install graphviz

import graphviz 
from graphviz import Source
dot_data = tree.export_graphviz(dtree, out_file=None, feature_names=X.columns)
graph = graphviz.Source(dot_data) 
graph.render("name of file",view = True)

I tried with my data, visualization worked well and I got a pdf file viewed immediately.

in case of a similar issue when I'm creating dockerfile I faced the same scenario:- I used below changed in mysql_connect function as:-

if($CONN = @mysqli_connect($DBHOST, $DBUSER, $DBPASS)){ //mysql_query("SET CHARACTER SET 'gbk'", $CONN);

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

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

Here is a method that will return your example:

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

locate Python.h

If the output is empty, then find your python version

python --version

lets say it is X.x i.e 2.7 or 3.6, 3.7, 3.8 Then with the same version install header files and static libraries for python

sudo apt-get install pythonX.x-dev

-L is the test for file exists and is also a symbolic link

If you do not want to test for the file being a symbolic link, but just test to see if it exists regardless of type (file, directory, socket etc) then use -e

So if file is really file and not just a symbolic link you can do all these tests and get an exit status whose value indicates the error condition.

if [ ! \( -e "${file}" \) ]
then
     echo "%ERROR: file ${file} does not exist!" >&2
     exit 1
elif [ ! \( -f "${file}" \) ]
then
     echo "%ERROR: ${file} is not a file!" >&2
     exit 2
elif [ ! \( -r "${file}" \) ]
then
     echo "%ERROR: file ${file} is not readable!" >&2
     exit 3
elif [ ! \( -s "${file}" \) ]
then
     echo "%ERROR: file ${file} is empty!" >&2
     exit 4
fi

What do you mean by better way:

more readable:

List<String> list = new ArrayList<String>(Arrays.asList(array));

less memory consumption, and maybe faster (but definitely not thread safe):

public static List<String> toList(String[] array) {
    if (array==null) {
       return new ArrayList(0);
    } else {
       int size = array.length;
       List<String> list = new ArrayList(size);
       for(int i = 0; i < size; i++) {
          list.add(array[i]);
       }
       return list;
    }
}

Btw: here is a bug in your first example:

array.length will raise a null pointer exception if array is null, so the check if (array!=null) must be done first.

The quickest fix for me was doing the following:

cd /usr/local
git reset --hard FETCH_HEAD

Then I retried brew install imagemagick and it correctly pulled the package from the new mirror, instead of adamv.

If that does not work, ensure that /Library/Caches/Homebrew does not contain any imagemagick files or folders. Delete them if it does.

You can run MSSQL and .NET Core on Linux, and hence inside Linux containers, nowadays.

See: https://hub.docker.com/r/microsoft/mssql-server-linux/

Also: https://hub.docker.com/r/microsoft/dotnet/

The direct question to your answer, is of course, unless there is a version compiled especially for Linux, no.

You can add it to your .bash_profile to have the version set by default.

//Open bash profile
open ~/.bash_profile

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

// run bash profile
source ~/.bash_profile

This is older but placing this here for my reference too. boto3.resource is just implementing the default Session, you can pass through boto3.resource session details.

Help on function resource in module boto3:

godbolt is a very useful tool, they list only has C++ compilers but you can use -x c flag in order to get it treat the code as C. It will then generate an assembly listing for your code side by side and you can use the Colourise option to generate colored bars to visually indicate which source code maps to the generated assembly. For example the following code:

#include <stdio.h>

void func()
{
  printf( "hello world\n" ) ;
}

using the following command line:

-x c -std=c99 -O3

and Colourise would generate the following:

Just my 2 cents regarding the divs option.

Famous/Infamous and SamsaraJS (and possibly others) use absolutely positioned non-nested divs (with non-trivial HTML/CSS content), combined with matrix2d/matrix3d for positioning and 2D/3D transformations, and achieve a stable 60FPS on moderate mobile hardware, so I'd argue against divs being a slow option.

There are plenty of screen recordings on Youtube and elsewhere, of high-performance 2D/3D stuff running in the browser with everything being an DOM element which you can Inspect Element on, at 60FPS (mixed with WebGL for certain effects, but not for the main part of the rendering).

You can try this:

((BigDecimal) volume).intValue();

I use java.math.BigDecimal convert to int (primitive type).

It is worked for me.

Ultimately, .keystore and .jks are just file extensions: it's up to you to name your files sensibly. Some application use a keystore file stored in $HOME/.keystore: it's usually implied that it's a JKS file, since JKS is the default keystore type in the Sun/Oracle Java security provider. Not everyone uses the .jks extension for JKS files, because it's implied as the default. I'd recommend using the extension, just to remember which type to specify (if you need).

In Java, the word keystore can have either of the following meanings, depending on the context:

• the API: http://docs.oracle.com/javase/6/docs/api/java/security/KeyStore.html
• a file (or other mechanism) that can be used to back this API
• a keystore as opposed to a truststore, as described here: https://stackoverflow.com/a/6341566/372643

When talking about the file and storage, this is not really a storage facility for key/value pairs (there are plenty or other formats for this). Rather, it's a container to store cryptographic keys and certificates (I believe some of them can also store passwords). Generally, these files are encrypted and password-protected so as not to let this data available to unauthorized parties.

Java uses its KeyStore class and related API to make use of a keystore (whether it's file based or not). JKS is a Java-specific file format, but the API can also be used with other file types, typically PKCS#12. When you want to load a keystore, you must specify its keystore type. The conventional extensions would be:

• .jks for type "JKS",
• .p12 or .pfx for type "PKCS12" (the specification name is PKCS#12, but the # is not used in the Java keystore type name).

In addition, BouncyCastle also provides its implementations, in particular BKS (typically using the .bks extension), which is frequently used for Android applications.

You can easily enable debugging support using an option for the @EnableWebSecurity annotation:

@EnableWebSecurity(debug = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    …
}

System.IO.File.ReadLines() is perfect for this scenario. It returns all the lines of a file, but lets you begin iterating over the lines immediately which means it does not have to store the entire contents in memory.

Requires .NET 4.0 or higher.

foreach ($line in [System.IO.File]::ReadLines($filename)) {
    # do something with $line
}

you should use rownum in oracle to do what you seek

where rownum <= 100

see also those answers to help you

If you want to parse the format yourself you could do it easily with a regex such as

private static Pattern pattern = Pattern.compile("(\\d{2}):(\\d{2}):(\\d{2}).(\\d{3})");

public static long dateParseRegExp(String period) {
    Matcher matcher = pattern.matcher(period);
    if (matcher.matches()) {
        return Long.parseLong(matcher.group(1)) * 3600000L 
            + Long.parseLong(matcher.group(2)) * 60000 
            + Long.parseLong(matcher.group(3)) * 1000 
            + Long.parseLong(matcher.group(4)); 
    } else {
        throw new IllegalArgumentException("Invalid format " + period);
    }
}

However, this parsing is quite lenient and would accept 99:99:99.999 and just let the values overflow. This could be a drawback or a feature.

I recently used ez_setup.py as well and I did a tutorial on how to install it. The tutorial has snapshots and simple to follow. You can find it below:

I hope you find this helpful.

This can also happen if you've recently upgraded Ant. I was using Ant 1.8.4 on a project, and upgraded Ant to 1.9.4, and started to get this error when building a fat jar using Ant.

The solution for me was to downgrade back to Ant 1.8.4 for the command line and Eclipse using the process detailed here

I was debugging an issue with git and needed some very verbose output to figure out what was going wrong. I ended up setting the GIT_TRACE environment variable:

export GIT_TRACE=1
git add *.txt

You can also use these on the same line:

GIT_TRACE=1 git add *.txt

Output:

14:06:05.508517 git.c:415               trace: built-in: git add test.txt test2.txt
14:06:05.544890 git.c:415               trace: built-in: git config --get oh-my-zsh.hide-dirty

The error message says it all: your connection timed out. This means your request did not get a response within some (default) timeframe. The reasons that no response was received is likely to be one of:

a) The IP/domain or port is incorrect

b) The IP/domain or port (i.e service) is down

c) The IP/domain is taking longer than your default timeout to respond

d) You have a firewall that is blocking requests or responses on whatever port you are using

e) You have a firewall that is blocking requests to that particular host

f) Your internet access is down

g) Your live-server is down i.e in case of "rest-API call".

Note that firewalls and port or IP blocking may be in place by your ISP

Adding a StreamHandler without arguments goes to stderr instead of stdout. If some other process has a dependency on the stdout dump (i.e. when writing an NRPE plugin), then make sure to specify stdout explicitly or you might run into some unexpected troubles.

Here's a quick example reusing the assumed values and LOGFILE from the question:

import logging
from logging.handlers import RotatingFileHandler
from logging import handlers
import sys

log = logging.getLogger('')
log.setLevel(logging.DEBUG)
format = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")

ch = logging.StreamHandler(sys.stdout)
ch.setFormatter(format)
log.addHandler(ch)

fh = handlers.RotatingFileHandler(LOGFILE, maxBytes=(1048576*5), backupCount=7)
fh.setFormatter(format)
log.addHandler(fh)

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

Just loop...

foreach(var table in DataSet1.Tables) {
    foreach(var col in table.Columns) {
       ...
    }
    foreach(var row in table.Rows) {
        object[] values = row.ItemArray;
        ...
    }
}

This function shows the last_value of each sequence.

It outputs a 2 columns table that says the sequence name plus it's last generated value.

drop function if exists public.show_sequence_stats();
CREATE OR REPLACE FUNCTION public.show_sequence_stats()
    RETURNS TABLE(tablename text, last_value bigint) 
    LANGUAGE 'plpgsql'
    COST 100
    VOLATILE 
    ROWS 1000
AS $BODY$
declare r refcursor; rec record; dynamic_query varchar;
        BEGIN
            dynamic_query='select tablename,last_value from (';
            open r for execute 'select nspname,relname from pg_class c join pg_namespace n on c.relnamespace=n.oid where relkind = ''S'' order by nspname'; 
            fetch next from r into rec;
            while found 
            loop
                dynamic_query=dynamic_query || 'select '''|| rec.nspname || '.' || rec.relname ||''' "tablename",last_value from ' || rec.nspname || '.' || rec.relname || ' union all ';
                fetch next from r into rec; 
            end loop;
            close r; 
            dynamic_query=rtrim(dynamic_query,'union all') || ') x order by last_value desc;';
            return query execute dynamic_query;
        END;
$BODY$;

select * from show_sequence_stats();
