If you want to restrict your search only to files you should consider to use -type f in your search

try to use also -iname for case-insensitive search

Example:

find /path -iname 'yourstring*' -type f

You could also perform some operations on results without pipe sign or xargs

Example:

Search for files and show their size in MB

find /path -iname 'yourstring*' -type f -exec du -sm {} \;

u can also show a certain number of digit after decimal point(here 2 digits) using following code :

var num = (15.46974).toFixed(2)_x000D_
console.log(num) // 15.47_x000D_
console.log(typeof num) // string

similar issue i was facing with my layout which consist scroll view inside. Whenever i try to select text in EditText,Copy/Cut/Paste action bar gets moved up with below code as such it does not resize layout

android:windowSoftInputMode="adjustPan"

By modifying it to as below

1) AndroidManifest.xml

android:windowSoftInputMode="stateVisible|adjustResize"

2) style.xml file ,in activity style

<item name="android:windowActionBarOverlay">true</item>

It worked.!!!!!!!!!!!!

struct and typedef are two very different things.

The struct keyword is used to define, or to refer to, a structure type. For example, this:

struct foo {
    int n;
};

creates a new type called struct foo. The name foo is a tag; it's meaningful only when it's immediately preceded by the struct keyword, because tags and other identifiers are in distinct name spaces. (This is similar to, but much more restricted than, the C++ concept of namespaces.)

A typedef, in spite of the name, does not define a new type; it merely creates a new name for an existing type. For example, given:

typedef int my_int;

my_int is a new name for int; my_int and int are exactly the same type. Similarly, given the struct definition above, you can write:

typedef struct foo foo;

The type already has a name, struct foo. The typedef declaration gives the same type a new name, foo.

The syntax allows you to combine a struct and typedef into a single declaration:

typedef struct bar {
    int n;
} bar;

This is a common idiom. Now you can refer to this structure type either as struct bar or just as bar.

Note that the typedef name doesn't become visible until the end of the declaration. If the structure contains a pointer to itself, you have use the struct version to refer to it:

typedef struct node {
    int data;
    struct node *next; /* can't use just "node *next" here */
} node;

Some programmers will use distinct identifiers for the struct tag and for the typedef name. In my opinion, there's no good reason for that; using the same name is perfectly legal and makes it clearer that they're the same type. If you must use different identifiers, at least use a consistent convention:

typedef struct node_s {
    /* ... */
} node;

(Personally, I prefer to omit the typedef and refer to the type as struct bar. The typedef save a little typing, but it hides the fact that it's a structure type. If you want the type to be opaque, this can be a good thing. If client code is going to be referring to the member n by name, then it's not opaque; it's visibly a structure, and in my opinion it makes sense to refer to it as a structure. But plenty of smart programmers disagree with me on this point. Be prepared to read and understand code written either way.)

(C++ has different rules. Given a declaration of struct blah, you can refer to the type as just blah, even without a typedef. Using a typedef might make your C code a little more C++-like -- if you think that's a good thing.)

It truly solved my problem using eval function.

single_quoted_dict_in_string = "{'key':'value', 'key2': 'value2'}"
desired_double_quoted_dict = eval(single_quoted_dict_in_string)
# Go ahead, now you can convert it into json easily
print(desired_double_quoted_dict)

I had to use the following with version 1.7.4

@import (less) "foo.css"

I know the accepted answer is @import (css) "foo.css" but it didn't work. If you want to reuse your css class in your new less file, you need to use (less) and not (css).

Check the documentation.

Which version of IntelliJ are you using? Note that since last year, IntelliJ exists in two versions:

• Ultimate Edition, which is the complete IDE
• Community Edition, which is free but does not support JavaEE developments.

(see differences here)

In case you are using the Community Edition, you will not be able to manage a Tomcat installation.

In case you are using the Ultimate Edition, you can have a look at:

• The FAQ for Netbeans users (see question How do I configure a web framework for my project?).
• IntelliJ Ultimate edition "Help": Run/Debug Configuration: Tomcat Server

Gradle looks for gradle.properties files in these places:

• in project build dir (that is where your build script is)
• in sub-project dir
• in gradle user home (defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle)

Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Reference: https://gradle.org/docs/current/userguide/build_environment.html

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

What you are doing is pass by value not pass by reference. Because you are sending the value of a variable 'p' to the function 'f' (in main as f(p);)

The same program in C with pass by reference will look like,(!!!this program gives 2 errors as pass by reference is not supported in C)

#include <stdio.h>

void f(int &j) {    //j is reference variable to i same as int &j = i
  j++;
}

int main() {
  int i = 20;
  f(i);
  printf("i = %d\n", i);

  return 0;
}

Output:-

3:12: error: expected ';', ',' or ')' before '&' token
             void f(int &j);
                        ^
9:3:  warning: implicit declaration of function 'f'
               f(a);
               ^

Swift 3

extension Date {
    
    func toString(template: String) -> String {
        let formatter = DateFormatter()
        formatter.dateFormat = DateFormatter.dateFormat(fromTemplate: template, options: 0, locale: NSLocale.current)
        return formatter.string(from: self)
    }
    
}

Usage

let now = Date()
let nowStr0 = now.toString(template: "EEEEdMMM") // Tuesday, May 9
let nowStr1 = now.toString(template: "yyyy-MM-dd") // 2017-05-09
let nowStr2 = now.toString(template: "HH:mm:ss") // 17:47:09

Play with template to match your needs. Examples and doc here to help you build the template you need.

Note

You may want to cache your DateFormatter if you plan to use it in TableView for instance. To give an idea, looping over 1000 dates took me 0.5 sec using the above toString(template: String) function, compared to 0.05 sec using myFormatter.string(from: Date).

To create a user with sudo privileges is to put the user into /etc/sudoers, or make the user a member of a group specified in /etc/sudoers. And to make it password-less is to additionally specify NOPASSWD in /etc/sudoers.

Example of /etc/sudoers:

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows people in group wheel to run all commands
%wheel  ALL=(ALL)       ALL

## Same thing without a password
%wheel  ALL=(ALL)       NOPASSWD: ALL

And instead of fiddling with /etc/sudoers file, we can create a new file in /etc/sudoers.d/ directory since this directory is included by /etc/sudoers by default, which avoids the possibility of breaking existing sudoers file, and also eliminates the dependency on the content inside of /etc/sudoers.

To achieve above in Ansible, refer to the following:

- name: sudo without password for wheel group
  copy:
    content: '%wheel ALL=(ALL:ALL) NOPASSWD:ALL'
    dest: /etc/sudoers.d/wheel_nopasswd
    mode: 0440

You may replace %wheel with other group names like %sudoers or other user names like deployer.

I would just go with

<tr @(if (count++ % 2 == 0){<text>class="alt-row"</text>})>

Or even better

<tr class="alt-row@(count++ % 2)">

this will give you lines like

<tr class="alt-row0">
<tr class="alt-row1">
<tr class="alt-row0">
<tr class="alt-row1">

Also be aware that when converting from numeric string ie '56.72' to INT you may come up against a SQL error.

Conversion failed when converting the varchar value '56.72' to data type int.

To get around this just do two converts as follows:

STRING -> NUMERIC -> INT

or

SELECT CAST(CAST (MyVarcharCol AS NUMERIC(19,4)) AS INT)

When copying data from TableA to TableB, the conversion is implicit, so you dont need the second convert (if you are happy rounding down to nearest INT):

INSERT INTO TableB (MyIntCol)
SELECT CAST(MyVarcharCol AS NUMERIC(19,4)) as [MyIntCol]
FROM TableA

For me, it happens when i set Project SDK as JAVA SDK 14 in a react-native project. Upon unset, all the folders show up again.

1. Probably you're using PlayServices of version 9.6.0. Then you should update it, it's library's bug. More info here.

OR

2. Add

   <uses-permission android:name="android.permission.READ_PHONE_STATE" tools:node="remove" />

to your manifest file.

You can imitate open source Dockerfile, for example:

Node: node12-github

RUN groupadd --gid 1000 node \
    && useradd --uid 1000 --gid node --shell /bin/bash --create-home node

superset: superset-github

RUN useradd --user-group --create-home --no-log-init --shell /bin/bash 
    superset

I think it's a good way to follow open source.

Just for something to do, I refactored the top answer into a class. The usage is something like:

var setting = configMan.GetAppSetting("AppSettingsKey");

Here is code for numeric keyboard : keyboardType: TextInputType.phone When you add this code in textfield it will open numeric keyboard.

  final _mobileFocus = new FocusNode();
  final _mobile = TextEditingController();


     TextFormField(
          controller: _mobile,
          focusNode: _mobileFocus,
          maxLength: 10,
          keyboardType: TextInputType.phone,
          decoration: new InputDecoration(
            counterText: "",
            counterStyle: TextStyle(fontSize: 0),
            hintText: "Mobile",
            border: InputBorder.none,
            hintStyle: TextStyle(
              color: Colors.black,
                fontSize: 15.0.
            ),
          ),
          style: new TextStyle(
              color: Colors.black,
              fontSize: 15.0,
           ),
          );

They both are indeed synonymous, However i found the small difference between them,

1)You cannot use Int32 while creatingenum

enum Test : Int32
{ XXX = 1   // gives you compilation error
}

enum Test : int
{ XXX = 1   // Works fine
}

2) Int32 comes under System declaration. if you remove using.System you will get compilation error but not in case for int

A other version of John Pick's solution just before, this works fine for me :

jQuery.ajax({
   ....
   success: function(data, textStatus, jqXHR) {
       jQuery(selecteur).html(jqXHR.responseText);
       var reponse = jQuery(jqXHR.responseText);
       var reponseScript = reponse.filter("script");
       jQuery.each(reponseScript, function(idx, val) { eval(val.text); } );
   }
   ...
});

Paul's answer is the one you're looking for. However, as a practical matter, I think you may be interested in the pattern I've been using in my own React+Redux apps.

Here's a stripped-down example from one of my routes, showing how you can define your component and export it as default with a single statement:

import React from 'react';
import { connect } from 'react-redux';

@connect((state, props) => ({
    appVersion: state.appVersion
    // other scene props, calculated from app state & route props
}))
export default class SceneName extends React.Component { /* ... */ }

(Note: I use the term "Scene" for the top-level component of any route).

I hope this is helpful. I think it's much cleaner-looking than the conventional connect( mapState, mapDispatch )( BareComponent )

The script webpack-dev-server is already installed inside ./node_modules directory. You can either install it again globally by

sudo npm install -g webpack-dev-server

or run it like this

./node_modules/webpack-dev-server/bin/webpack-dev-server.js -d --config webpack.dev.config.js --content-base public/ --progress --colors

. means look it in current directory.

A more efficient way, in my opinion, is to have another list that you declare that you put anything that is "to be removed" into. Then after you finish your main loop (without the .ToList()), you do another loop over the "to be removed" list, removing each entry as it happens. So in your class you add:

private List<Guid> toBeRemoved = new List<Guid>();

Then you change it to:

public void NotifySubscribers(DataRecord sr)
{
    toBeRemoved.Clear();

    ...your unchanged code skipped...

   foreach ( Guid clientId in toBeRemoved )
   {
        try
        {
            subscribers.Remove(clientId);
        }
        catch(Exception e)
        {
            System.Diagnostics.Debug.WriteLine("Unsubscribe Error " + 
                e.Message);
        }
   }
}

...your unchanged code skipped...

public void UnsubscribeEvent(Guid clientId)
{
    toBeRemoved.Add( clientId );
}

This will not only solve your problem, it will prevent you from having to keep creating a list from your dictionary, which is expensive if there are a lot of subscribers in there. Assuming the list of subscribers to be removed on any given iteration is lower than the total number in the list, this should be faster. But of course feel free to profile it to be sure that's the case if there's any doubt in your specific usage situation.

An API is a set of commands, functions, and protocols which programmers can use when building software for a specific OS or any other software. The API allows programmers to use predefined functions to interact with the operating system, instead of writing them from scratch. All computer operating systems, such as Windows, Unix, and the Mac OS and language such as Java provide an application program interface for programmers.

my.data.frame <- subset(data , V1 > 2 | V2 < 4)

An alternative solution that mimics the behavior of this function and would be more appropriate for inclusion within a function body:

new.data <- data[ which( data$V1 > 2 | data$V2 < 4) , ]

Some people criticize the use of which as not needed, but it does prevent the NA values from throwing back unwanted results. The equivalent (.i.e not returning NA-rows for any NA's in V1 or V2) to the two options demonstrated above without the which would be:

 new.data <- data[ !is.na(data$V1 | data$V2) & ( data$V1 > 2 | data$V2 < 4)  , ]

Note: I want to thank the anonymous contributor that attempted to fix the error in the code immediately above, a fix that got rejected by the moderators. There was actually an additional error that I noticed when I was correcting the first one. The conditional clause that checks for NA values needs to be first if it is to be handled as I intended, since ...

> NA & 1
[1] NA
> 0 & NA
[1] FALSE

Order of arguments may matter when using '&".

I'd like to add my own efforts to this list. You can find out more information here:

brzy framework

It's in early development and I'm still working on it aggressively. It includes features like:

• A focus on simplicity and extensibility.
• Integrated build tool.
• Modular design; some initial modules includes support for scalate, email, jms, jpa, squeryl, cassandra, cron services and more.
• Simple RESTful controllers and actions.

Any and all feedback is much appreciated.

UPDATE: 2011-09-078, I just posted a major update to version 0.9.1. There's more info at http://brzy.org which includes a screencast.

To list the patches using sql :

select * from registry$history;

This is how I was able to trigger a button click when the page loads.

<li ng-repeat="a in array">
  <a class="button" id="btn" ng-click="function(a)" index="$index" on-load-clicker>
    {{a.name}}
  </a>
</li>

A simple directive that takes the index from the ng-repeat and uses a condition to call the first button in the index and click it when the page loads.

angular
    .module("myApp")
        .directive('onLoadClicker', function ($timeout) {
            return {
                restrict: 'A',
                scope: {
                    index: '=index'
                },
                link: function($scope, iElm) {
                    if ($scope.index == 0) {
                        $timeout(function() {

                            iElm.triggerHandler('click');

                        }, 0);
                    }
                }
            };
        });

This was the only way I was able to even trigger an auto click programmatically in the first place. angular.element(document.querySelector('#btn')).click(); Did not work from the controller so making this simple directive seems most effective if you are trying to run a click on page load and you can specify which button to click by passing in the index. I got help through this stack-overflow answer from another post reference: https://stackoverflow.com/a/26495541/4684183 onLoadClicker Directive.

if the document.domain property is set in the parent page, Internet Explorer gives me an "Access is denied"

Sigh. Yeah, it's an IE issue (bug? difficult to say as there is no documented standard for this kind of unpleasantness). When you create a srcless iframe it receives a document.domain from the parent document's location.host instead of its document.domain. At that point you've pretty much lost as you can't change it.

A horrendous workaround is to set src to a javascript: URL (urgh!):

 iframe.src= "javascript:'<html><body><p>Hello<\/p><script>do things;<\/script>'";

But for some reason, such a document is unable to set its own document.domain from script in IE (good old “unspecified error”), so you can't use that to regain a bridge between the parent(*). You could use it to write the whole document HTML, assuming the widget doesn't need to talk to its parent document once it's instantiated.

However iframe JavaScript URLs don't work in Safari, so you'd still need some kind of browser-sniffing to choose which method to use.

*: For some other reason, you can, in IE, set document.domain from a second document, document.written by the first document. So this works:

if (isIE)
    iframe.src= "javascript:'<script>window.onload=function(){document.write(\\'<script>document.domain=\\\""+document.domain+"\\\";<\\\\/script>\\');document.close();};<\/script>'";

At this point the hideousness level is too high for me, I'm out. I'd do the external HTML like David said.

Sounds like you forgot to add a mapping assembly to the session factory configuration..

If you're using app.config...

It looks like whichever program or process you're trying to initialize either isn't installed on your machine, has a damaged installation or needs to be registered.

Either install it, repair it (via Add/Remove Programs) or register it (via Regsvr32.exe).

You haven't provided enough information for us to help you any more than this.

I had the same on Android. This is how i fixed it:

including ONLY the file:

slf4j-api-1.7.6.jar

in my libs/ folder

Having any additional slf4j* file, caused the NoClassDefFoundError.

Obviously, the rest of the libs can be there (android-support-v4, etc)

Versions: Eclipse Kepler 2013 06 14 - 02 29 ADT 22.3 Android SDK: 4.4.2

Hope someone saves the time i wasted thanks to this!

If you want another approach for solving it that is does not depend on value_counts or scipy.stats you can use the Counter collection

from collections import Counter
get_most_common = lambda values: max(Counter(values).items(), key = lambda x: x[1])[0]

Which can be applied to the above example like this

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

src.groupby(['Country','City']).agg(get_most_common)

I got this to finally work in a semi-automatic fashion without the use of scripts... but it does take up 3 cells to pull it off. Borrowing from a bit from previous answers, I start with a cell that has nothing more than =NOW() it in to show the time. For example, we'll put this into cell A1...

=NOW()

This function updates automatically every minute. In the next cell, put a pointer formula using the sheets own name to point to the previous cell. For example, we'll put this in A2...

='Sheet Name'!A1

Cell formatting aside, cell A1 and A2 should at this point display the same content... namely the current time.

And, the last cell is the part I'm borrowing from previous solutions using a regex expression to pull the fomula from the second cell and then strip out the name of the sheet from said formula. For example, we'll put this into cell A3...

=REGEXREPLACE(FORMULATEXT(A2),"='?([^']+)'?!.*","$1")

At this point, the resultant value displayed in A3 should be the name of the sheet.

From my experience, as soon as the name of the sheet is changed, the formula in A2 is immediately updated. However that's not enough to trigger A3 to update. But, every minute when cell A1 recalculates the time, the result of the formula in cell A2 is subsequently updated and then that in turn triggers A3 to update with the new sheet name. It's not a compact solution... but it does seem to work.

If you have multiple Action within same file then pass the same argument e.g. Id to all Action. This is because action only can identify Id, So instead of giving any name to argument only declare Id like this.

[httpget]
[ActionName("firstAction")] firstAction(string Id)
{.....
.....
}
[httpget]
[ActionName("secondAction")] secondAction(Int Id)
{.....
.....
}
//Now go to webroute.config file under App-start folder and add following
routes.MapHttpRoute(
name: "firstAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);

routes.MapHttpRoute(
name: "secondAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);

try this

List<String> list = new ArrayList<String>();
list.add("List1");
list.add("List2");

String[] listArr = new String[list.size()];
listArr = list.toArray(listArr );

for(String s : listArr )
    System.out.println(s);

Use the HAVING clause and GROUP By the fields that make the row unique

The below will find

all users that have more than one payment per day with the same account number

SELECT 
 user_id ,
 COUNT(*) count
FROM 
 PAYMENT
GROUP BY
 account,
 user_id ,
 date
HAVING
COUNT(*) > 1

Update If you want to only include those that have a distinct ZIP you can get a distinct set first and then perform you HAVING/GROUP BY

 SELECT 
    user_id,
    account_no , 
    date,
        COUNT(*)
 FROM
    (SELECT DISTINCT
            user_id,
            account_no , 
            zip, 
            date
         FROM
            payment 
    
        ) 
        payment
 GROUP BY
    
    user_id,
    account_no , 
    
    date
HAVING COUNT(*) > 1

This is code for live Video thumbnail.

public class LoadVideoThumbnail extends AsyncTask<Object, Object, Bitmap>{

        @Override
        protected Bitmap doInBackground(Object... params) {try {

            String mMediaPath = "http://commonsware.com/misc/test2.3gp";
            Log.e("TEST Chirag","<< thumbnail doInBackground"+ mMediaPath);
            FileOutputStream out;
            File land=new File(Environment.getExternalStorageDirectory().getAbsoluteFile()
                            +"/portland.jpg");

                Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(mMediaPath, MediaStore.Video.Thumbnails.MICRO_KIND);
                        ByteArrayOutputStream stream = new ByteArrayOutputStream();

                        byte[] byteArray = stream.toByteArray();

                        out=new  FileOutputStream(land.getPath());
                        out.write(byteArray);
                        out.close();

        protected void onPostExecute(Bitmap result) {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
            if(result != null){
                 ((ImageView)findViewById(R.id.imageView1)).setImageBitmap(result);

        }

    }

In Python mutable objects are passed as reference, so you can pass a reference of the outer class to the inner class.

class OuterClass:
    def __init__(self):
        self.outer_var = 1
        self.inner_class = OuterClass.InnerClass(self)
        print('Inner variable in OuterClass = %d' % self.inner_class.inner_var)

    class InnerClass:
        def __init__(self, outer_class):
            self.outer_class = outer_class
            self.inner_var = 2
            print('Outer variable in InnerClass = %d' % self.outer_class.outer_var)

See: RFC 3092: Etymology of "Foo", D. Eastlake 3rd et al.

Quoting only the relevant definitions from that RFC for brevity:

2. Used very generally as a sample name for absolutely anything, esp. programs and files (esp. scratch files).

3. First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud). [JARGON]

If your onclick function returns false the default browser behaviour is cancelled. As such:

<a href='http://www.google.com' onclick='return check()'>check</a>

<script type='text/javascript'>

function check()
{
    return false;
}

</script>

Either way, whether google does it or not isn't of much importance. It's cleaner to bind your onclick functions within javascript - this way you separate your HTML from other code.

in android i did this using kotlin:

private fun angleBetweenPoints(a: PointF, b: PointF): Double {
        val deltaY = abs(b.y - a.y)
        val deltaX = abs(b.x - a.x)
        return Math.toDegrees(atan2(deltaY.toDouble(), deltaX.toDouble()))
    }

Have a look at the documentation. You can have a .env file which picks up the PUBLIC_URL

Although you should remember that what its used for -

You may use this variable to force assets to be referenced verbatim to the url you provide (hostname included). This may be particularly useful when using a CDN to host your application.

All DECLAREs need to be at the top. ie.

delimiter //

CREATE TRIGGER pgl_new_user 
AFTER INSERT ON users FOR EACH ROW
BEGIN
    DECLARE m_user_team_id integer;
    DECLARE m_projects_id integer;
    DECLARE cur CURSOR FOR SELECT project_id FROM user_team_project_relationships WHERE user_team_id = m_user_team_id;

    SET @m_user_team_id := (SELECT id FROM user_teams WHERE name = "pgl_reporters");

    OPEN cur;
        ins_loop: LOOP
            FETCH cur INTO m_projects_id;
            IF done THEN
                LEAVE ins_loop;
            END IF;
            INSERT INTO users_projects (user_id, project_id, created_at, updated_at, project_access) 
            VALUES (NEW.id, m_projects_id, now(), now(), 20);
        END LOOP;
    CLOSE cur;
END//

simply import :

Did you try

string.trim(); 

This is meant to trim all leading and leaning while spaces in the string. Hope this helps.

Edit: (I was not explicit enough)

So, when you string.split(), you will have a string[] - for each of the strings in the array, do a string.trim() and then append it.

String[] tokens = yourString.split(" ");
StringBuffer buff = new StringBuffer();
for (String token : tokens)
{
  buff.append(token.trim());
}

Use stringBuffer/Builder instead of appending in the same string.

First you should use print_r($_FILES) to debug, and see what it contains. :

your uploads.php would look like:

//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];


//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
    // Connects to your Database
    mysql_connect("localhost", "root", "") or die(mysql_error()) ;
    mysql_select_db("altabotanikk") or die(mysql_error()) ;

    //Writes the information to the database
    mysql_query("INSERT INTO picture (Filename,Description)
    VALUES ('$Filename', '$Description')") ;
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}



?>

EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php

Your code is correct. Just put them inside the <VirtualHost *:443>

Example:

<VirtualHost *:443>
  SSLEnable

  RewriteEngine On
  RewriteCond %{HTTPS} on
  RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI}

</VirtualHost>

Use style="display:none" in your dropdown list tag and in jquery use the following to display and hide.

$("#yourdropdownid").css('display', 'inline');

OR

$("#yourdropdownid").css('display', 'none');

I already found it:

SELECT grantee, privilege_type 
FROM information_schema.role_table_grants 
WHERE table_name='mytable'

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

R> de <- merge(d, e, by=0, all=TRUE)  # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0                 # replace NA values
R> de

We can simply state that when a superclass is inherited, then the private members of superclass actually become private members of the subclass and cannot be further inherited or are inacessible to the objects of subclass.

The shorthand is:

$(function() {
    // Code here
});

I think the V$SQLAREA table contains what you're looking for (see columns SQL_TEXT and SQL_FULLTEXT).

Based on your comment to Issun:

Thanks for the explanation. In my case, The object is declared and created prior to the If condition. So, How do I use If condition to check for < No Variables> ? In other words, I do not want to execute My_Object.Compute if My_Object has < No Variables>

You need to check one of the properties of the object. Without telling us what the object is, we cannot help you.

I did test several common objects and found that an instantiated Collection with no items added shows <No Variables> in the watch window. If your object is indeed a collection, you can check for the <No Variables> condition using the .Count property:

Sub TestObj()
Dim Obj As Object
    Set Obj = New Collection
    If Obj Is Nothing Then
        Debug.Print "Object not instantiated"
    Else
        If Obj.Count = 0 Then
            Debug.Print "<No Variables> (ie, no items added to the collection)"
        Else
            Debug.Print "Object instantiated and at least one item added"
        End If
    End If
End Sub

It is also worth noting that if you declare any object As New then the Is Nothing check becomes useless. The reason is that when you declare an object As New then it gets created automatically when it is first called, even if the first time you call it is to see if it exists!

Dim MyObject As New Collection
If MyObject Is Nothing Then  ' <--- This check always returns False

This does not seem to be the cause of your specific problem. But, since others may find this question through a Google search, I wanted to include it because it is a common beginner mistake.

Since you're using asp.net code-behind, add an id to the element and runat=server.

You can then reference the objects in the code behind.

First alpha of eclipse word wrap released!

Got this answer from this post: How can I get word wrap to work in Eclipse PDT for PHP files?

public class Main {
 public static void main(String args[]) {
   String format = "|%1$-10s|%2$-10s|%3$-20s|\n";
   System.out.format(format, "A", "AA", "AAA");
   System.out.format(format, "B", "", "BBBBB");
   System.out.format(format, "C", "CCCCC", "CCCCCCCC");

   String ex[] = { "E", "EEEEEEEEEE", "E" };

   System.out.format(String.format(format, (Object[]) ex));
 }
}

differece in sizes of input doesnt effect the output

It is not possible to use relative paths for AuthUserFile:

File-path is the path to the user file. If it is not absolute (i.e., if it doesn't begin with a slash), it is treated as relative to the ServerRoot.

You have to accept and work around that limitation.

We're using IfDefine together with an apache2 command line parameter:

.htaccess (suitable for both development and live systems):

<IfDefine !development>
  AuthType Basic
  AuthName "Say the secret word"
  AuthUserFile /var/www/hostname/.htpasswd
  Require valid-user
</IfDefine>

Development server configuration (Debian)

Append the following to /etc/apache2/envvars:

export APACHE_ARGUMENTS=-Ddevelopment

Restart your apache afterwards and you'll get a password prompt only when you're not on the development server.

You can of course add another IfDefine for the development server, just copy the block and remove the !.

You could use replicate or sapply:

R> colMeans(replicate(10000, sample(100, size=815, replace=TRUE, prob=NULL))) R> sapply(seq_len(10000), function(...) mean(sample(100, size=815, replace=TRUE, prob=NULL))) 

replicate is a wrapper for the common use of sapply for repeated evaluation of an expression (which will usually involve random number generation).

I had some trouble with $scope.$watch but after a lot of testing I found out that my data-ng-model="User.UserName" was badly named and after I changed it to data-ng-model="UserName" everything worked fine. I expect it to be the . in the name causing the issue.

Try CountA:

Dim myArray(1 to 10) as String
Dim arrayCount as String
arrayCount = Application.CountA(myArray)
Debug.Print arrayCount

To easily debug Ruby shell script, just change its first line from:

#!/usr/bin/env ruby

to:

#!/usr/bin/env ruby -rdebug

Then every time when debugger console is shown, you can choose:

• c for Continue (to the next Exception, breakpoint or line with: debugger),
• n for Next line,
• w/where to Display frame/call stack,
• l to Show the current code,
• cat to show catchpoints.
• h for more Help.

See also: Debugging with ruby-debug, Key shortcuts for ruby-debug gem.

In case the script just hangs and you need a backtrace, try using lldb/gdb like:

echo 'call (void)rb_backtrace()' | lldb -p $(pgrep -nf ruby)

and then check your process foreground.

Replace lldb with gdb if works better. Prefix with sudo to debug non-owned process.

We will find the value of X and Y from this image. We know, sin?=vertical/hypotenuse and cos?=base/hypotenuse from the image we can say X=base and Y=vertical. Now we can write X=hypotenuse * cos? and Y=hypotenuse * sin?.

Now look at this code

void display(){
float x,y;
glColor3f(1, 1, 0);
for(double i =0; i <= 360;){
    glBegin(GL_TRIANGLES);
    x=5*cos(i);
    y=5*sin(i);
    glVertex2d(x, y);
    i=i+.5;
    x=5*cos(i);
    y=5*sin(i);
    glVertex2d(x, y);
    glVertex2d(0, 0);
    glEnd();
    i=i+.5;
}
glEnd();

glutSwapBuffers();
}

Ganymede's version of WTP includes a revamped Javascript editor that's worth a try. The key version numbers are Eclipse 3.4 and WTP 3.0. See http://live.eclipse.org/node/569

If the query is not too complicated you can do something like this. In my case i needed to use a H2 FT_Search result query to make another query.

var ftSearchQuery = "SELECT * FROM FT_SEARCH(\'something\', 0, 0)";
List<Object[]> results = query.getResultList();
List<Model> models = new ArrayList<>();
for (Object[] result : results) {
    var newQuery = "SELECT * FROM " + (String) result[0];
    models.addAll(entityManager.createNativeQuery(newQuery, Model.class).getResultList());
  }

There are probably cleaner way to do this.

Add:

allow_url_fopen=1

in your php.ini file. If you are using shared hosting, create one first.

Here is a solution using DictVectorizer and the Pandas DataFrame.to_dict('records') method.

>>> import pandas as pd
>>> X = pd.DataFrame({'income': [100000,110000,90000,30000,14000,50000],
                      'country':['US', 'CAN', 'US', 'CAN', 'MEX', 'US'],
                      'race':['White', 'Black', 'Latino', 'White', 'White', 'Black']
                     })

>>> from sklearn.feature_extraction import DictVectorizer
>>> v = DictVectorizer()
>>> qualitative_features = ['country','race']
>>> X_qual = v.fit_transform(X[qualitative_features].to_dict('records'))
>>> v.vocabulary_
{'country=CAN': 0,
 'country=MEX': 1,
 'country=US': 2,
 'race=Black': 3,
 'race=Latino': 4,
 'race=White': 5}

>>> X_qual.toarray()
array([[ 0.,  0.,  1.,  0.,  0.,  1.],
       [ 1.,  0.,  0.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  0.,  1.,  0.],
       [ 1.,  0.,  0.,  0.,  0.,  1.],
       [ 0.,  1.,  0.,  0.,  0.,  1.],
       [ 0.,  0.,  1.,  1.,  0.,  0.]])

I have Python 2.7.5, MySQL 5.6 and CentOS 7.1.1503.

For me it worked with the following command:

# pip install mysql-python

Note pre-requisites here:

Install Python pip:

# rpm -iUvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

# yum -y update
Reboot the machine (if kernel is also updated)

# yum -y install python-pip

Install Python devel packages:

# yum install python-devel

Install MySQL devel packages:

# yum install mysql-devel

Factory Method patter: BeanFactory for creating instance of an object Singleton : instance type can be singleton for a context Prototype : instance type can be prototype. Builder pattern: you can also define a method in a class who will be responsible for creating complex instance.

Your problem is probably that a elements are display: inline by nature. You can't set the width and height of inline elements.

You would have to set display: block on the a, but that will bring other problems because the links start behaving like block elements. The most common cure to that is giving them float: left so they line up side by side anyway.

This Twilio blog page made on March 24, 2017 by Marcos Placona may be helpful.

Google Spreadsheets and .NET Core

It references Google.Api.Sheets.v4 and OAuth2.

If escaping your single quote with another single quote isn't working for you (like it didn't for one of my recent REPLACE() queries), you can use SET QUOTED_IDENTIFIER OFF before your query, then SET QUOTED_IDENTIFIER ON after.

For example

SET QUOTED_IDENTIFIER OFF;

UPDATE TABLE SET NAME = REPLACE(NAME, "'S", "S");

SET QUOTED_IDENTIFIER OFF;

The way I did it while navigating to different page add a query param by passing current location

this.router.navigate(["user/edit"], { queryParams: { returnUrl: this.router.url }

Read this query param in your component

this.router.queryParams.subscribe((params) => {
    this.returnUrl = params.returnUrl;
});

If returnUrl is present enable the back button and when user clicks the back button

this.router.navigateByUrl(this.returnUrl); // Hint taken from Sasxa

This should able to navigate to previous page. Instead of using location.back I feel the above method is more safe consider the case where user directly lands to your page and if he presses the back button with location.back it will redirects user to previous page which will not be your web page.

On bulk inserts

Inspired by this post and by the Stack Overflow question that led me here -- Is it possible to insert multiple rows at a time in an SQLite database? -- I've posted my first Git repository:

https://github.com/rdpoor/CreateOrUpdate

which bulk loads an array of ActiveRecords into MySQL, SQLite or PostgreSQL databases. It includes an option to ignore existing records, overwrite them or raise an error. My rudimentary benchmarks show a 10x speed improvement compared to sequential writes -- YMMV.

I'm using it in production code where I frequently need to import large datasets, and I'm pretty happy with it.

The other one doesn't work. According to the docs this is the way you should do it.

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal) {

    var modalInstance = $modal.open({
      templateUrl: 'myModalContent.html',
      controller: ModalInstanceCtrl,
      resolve: {
        test: function () {
          return 'test variable';
        }
      }
    });
};

var ModalInstanceCtrl = function ($scope, $modalInstance, test) {

  $scope.test = test;
};

See plunkr

You should pre authenticate the token apis "/oauth/token"

extend ResourceServerConfigurerAdapter and override configure function to do this.

eg:

http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and().authorizeRequests().antMatchers("/oauth/token").permitAll().
anyRequest().authenticated();

Redirect sys.stdout to an open file handle and then all printed output goes to a file:

import sys
filename  = open("outputfile",'w')
sys.stdout = filename
print "Anything printed will go to the output file"

The id should set as auto-increment.

To modify an existing id column to auto-increment, just add this

ALTER TABLE card_games MODIFY id int NOT NULL AUTO_INCREMENT;

The first argument should be the path to the executable program. So

gdb progname 12271

If you want to save to a specific filename just ignore the provided extensions in Notepad/Word/whatever. Just set the filename.ext in " " and you're done. "Save as type" will be ignored.

For those using sdkman, this helped me.

Use Case:
I was using identifier 8.0.202-amzn
I decided to install Azul Zulu as follows: sdk install java 13.0.2-zulu

Error: And then i got this unbound error.

Solution:
1. Right-click on your project in Eclipse/STS
2. Choose Build Path > Configure Build Path...
3. Under Libraries, remove the JRE Library, for my case 8.0.202-amzn
4. Under Libraries, click on Modulepath > Add Library...
5. Choose JRE System Library, click Next
6. Choose Alternate JRE, click on Installed JREs...
7. Your previous configured value should be there
8. If it is there, edit it, if it is not there, add one
9. Make sure the name is: 13.0.2-zulu
10. And the location(JRE home) is: /Users/jumping_monkey/.sdkman/candidates/java/current
11. Click Apply and close
12. Click Finish
13. Voila!

You will see JRE System Library [13.0.2-zulu] in your Project Explorer and all errors gone

Bravo!

There's no NotifyIcon for WPF.

A colleague of mine used this freely available library to good effect:

• http://www.hardcodet.net/wpf-notifyicon (blog post)
• https://bitbucket.org/hardcodet/notifyicon-wpf/src (source code)
• https://www.nuget.org/packages/Hardcodet.NotifyIcon.Wpf/ (NuGet package)
• http://visualstudiogallery.msdn.microsoft.com/aacbc77c-4ef6-456f-80b7-1f157c2909f7/

In general, bless associates an object with a class.

package MyClass;
my $object = { };
bless $object, "MyClass";

Now when you invoke a method on $object, Perl know which package to search for the method.

If the second argument is omitted, as in your example, the current package/class is used.

For the sake of clarity, your example might be written as follows:

sub new { 
  my $class = shift; 
  my $self = { }; 
  bless $self, $class; 
} 

EDIT: See kixx's good answer for a little more detail.

Use: "%.2f" or variations on that.

See the POSIX spec for an authoritative specification of the printf() format strings. Note that it separates POSIX extras from the core C99 specification. There are some C++ sites which show up in a Google search, but some at least have a dubious reputation, judging from comments seen elsewhere on SO.

Since you're coding in C++, you should probably be avoiding printf() and its relatives.

You can call a reset function before appending. Something like this:

    function resetNewReviewBoardForm() {
    $("#Description").val('');
    $("#PersonName").text('');
    $("#members").empty(); //this one what worked in my case
    $("#EmailNotification").val('False');
}

You can find all of those operators in the Python language reference, though you'll have to scroll around a bit to find them all. As other answers have said:

• The ** operator does exponentiation. a ** b is a raised to the b power. The same ** symbol is also used in function argument and calling notations, with a different meaning (passing and receiving arbitrary keyword arguments).
• The ^ operator does a binary xor. a ^ b will return a value with only the bits set in a or in b but not both. This one is simple!
• The % operator is mostly to find the modulus of two integers. a % b returns the remainder after dividing a by b. Unlike the modulus operators in some other programming languages (such as C), in Python a modulus it will have the same sign as b, rather than the same sign as a. The same operator is also used for the "old" style of string formatting, so a % b can return a string if a is a format string and b is a value (or tuple of values) which can be inserted into a.
• The // operator does Python's version of integer division. Python's integer division is not exactly the same as the integer division offered by some other languages (like C), since it rounds towards negative infinity, rather than towards zero. Together with the modulus operator, you can say that a == (a // b)*b + (a % b). In Python 2, floor division is the default behavior when you divide two integers (using the normal division operator /). Since this can be unexpected (especially when you're not picky about what types of numbers you get as arguments to a function), Python 3 has changed to make "true" (floating point) division the norm for division that would be rounded off otherwise, and it will do "floor" division only when explicitly requested. (You can also get the new behavior in Python 2 by putting from __future__ import division at the top of your files. I strongly recommend it!)

You're removing and then incrementing, which means you'll be one ahead of yourself. Instead, remove in reverse so you never mess up your next item.

for (int i = ChunkList.Count-1; i >=0; i--)
{
    if (ChunkList[i].UniqueID == ChunkID)
    {
        ChunkList.RemoveAt(i);
    }
}

There are many scenarios where you want to commit a directory to your Git repo but without the files in it, for example the logs, cache, uploads directories etc.

So what I always do is to add a .gitignore file in those directories with the following content:

*
!.gitignore

With this .gitignore file, Git will not track any files in those directories yet still allow me to add the .gitignore file and hence the directory itself to the repo.

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

While you can use rand(42-10) + 10 to get a random number between 10 and 42 (where 10 is inclusive and 42 exclusive), there's a better way since Ruby 1.9.3, where you are able to call:

rand(10...42) # => 13

Available for all versions of Ruby by requiring my backports gem.

Ruby 1.9.2 also introduced the Random class so you can create your own random number generator objects and has a nice API:

r = Random.new
r.rand(10...42) # => 22
r.bytes(3) # => "rnd"

The Random class itself acts as a random generator, so you call directly:

Random.rand(10...42) # => same as rand(10...42)

Notes on Random.new

In most cases, the simplest is to use rand or Random.rand. Creating a new random generator each time you want a random number is a really bad idea. If you do this, you will get the random properties of the initial seeding algorithm which are atrocious compared to the properties of the random generator itself.

If you use Random.new, you should thus call it as rarely as possible, for example once as MyApp::Random = Random.new and use it everywhere else.

The cases where Random.new is helpful are the following:

• you are writing a gem and don't want to interfere with the sequence of rand/Random.rand that the main programs might be relying on
• you want separate reproducible sequences of random numbers (say one per thread)
• you want to be able to save and resume a reproducible sequence of random numbers (easy as Random objects can marshalled)

if you think you followed everything good but still unlucky, just make sure you/capistrano run touch tmp/restart.txt or equivalent at the end. I was in the unlucky list but now :)

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

You can explicitly have a join like this:

$qb->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId');

But you need to use the namespace of the class Join from doctrine:

use Doctrine\ORM\Query\Expr\Join;

Or if you prefere like that:

$qb->innerJoin('c.phones', 'p', Doctrine\ORM\Query\Expr\Join::ON, 'c.id = p.customerId');

Otherwise, Join class won't be detected and your script will crash...

Here the constructor of the innerJoin method:

public function innerJoin($join, $alias, $conditionType = null, $condition = null);

You can find other possibilities (not just join "ON", but also "WITH", etc...) here: http://docs.doctrine-project.org/en/2.0.x/reference/query-builder.html#the-expr-class

EDIT

Think it should be:

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId')
    ->where('c.username = :username')
    ->andWhere('p.phone = :phone');

    $qb->setParameters(array(
        'username' => $username,
        'phone' => $phone->getPhone(),
    ));

Otherwise I think you are performing a mix of ON and WITH, perhaps the problem.

If you are referring to the System.Net.HttpClient in .NET 4.5, you can get the content returned by GetAsync using the HttpResponseMessage.Content property as an HttpContent-derived object. You can then read the contents to a string using the HttpContent.ReadAsStringAsync method or as a stream using the ReadAsStreamAsync method.

The HttpClient class documentation includes this example:

  HttpClient client = new HttpClient();
  HttpResponseMessage response = await client.GetAsync("http://www.contoso.com/");
  response.EnsureSuccessStatusCode();
  string responseBody = await response.Content.ReadAsStringAsync();

The replacement with snprintf is NOT complete!

It covers only bases: 2, 8, 10, 16, whereas itoa works for bases between 2 and 36.

Since I was searching a replacement for base 32, I guess I'll have to code my own!

Since this is the top result on Google:

If your connection works initially, but you begin seeing this error after many successful connections, it may be this issue.

In summary: if you open and close a connection, Windows reserves the TCP port for future use for some stupid reason. After doing this many times, it runs out of available ports.

The article gives a registry hack to fix the issue...

Here are my registry settings on XP/2003:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort 0xFFFF (DWORD)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort\TcpTimedWaitDelay 60 (DWORD)

You need to create them. By default they don't exists.

On Vista/2008 you can use netsh to change it to something like:

netsh int ipv4 set dynamicport tcp start=10000 num=50000

...but the real solution is to use connection pooling, so that "opening" a connection really reuses an existing connection. Most frameworks do this automatically, but in my case the application was handling connections manually for some reason.

[^] ( within [ ] ) is negation in regular expression whereas ^ is "begining of string"

[^a-z] matches any single character that is not from "a" to "z"

^[a-z] means string starts with from "a" to "z"

Reference

curl --head https://www.example.net

I was pointed to this by curl itself; when I issued the command with -X HEAD, it printed:

Warning: Setting custom HTTP method to HEAD with -X/--request may not work the 
Warning: way you want. Consider using -I/--head instead.

For handling line-breaks specifically, I tried a number of options before finally settling for this:

{% set list1 = data.split('\n') %}
{% for item in list1 %}
{{ item }}
  {% if not loop.last %}
  <br/>
  {% endif %}
{% endfor %}

The nice thing about this approach is that it's compatible with the auto-escaping, leaving everything nice and safe. It can also be combined with filters, like urlize.

Of course it's similar to Helge's answer, but doesn't need a macro (relying instead on Jinja's built-in split function) and also doesn't add an unnecesssary <br/> after the last item.

You can also use chmod 777 *

This will give permissions to all files currently in the folder and files added in the future without giving permissions to the directory itself.

NOTE: This should be done in the folder where the files are located. For me it was an images that had an issue so I went to my images folder and did this.

You can add a new source directory with build-helper:

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>build-helper-maven-plugin</artifactId>
            <version>3.2.0</version>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>add-source</goal>
                    </goals>
                    <configuration>
                        <sources>
                            <source>src/main/generated</source>
                        </sources>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

Here is my Suggestion:

First: 
      1. Add display: block or table
      2. Add position: relative
      3. Add width:(percentage also works fine)
Second: 
      if above trick not works then you have to add float:none;

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

I'm late to the game here but in-case others want an easy solution, I created a set of functions which can be called like:

 ggplot + scale_x_continuous(labels = human_gbp)

which give you human readable numbers for x or y axes (or any number in general really).

You can find the functions here: Github Repo Just copy the functions in to your script so you can call them.

On Safari Mac for an HLS source, I needed to use the loadeddata event instead of the metadata event.

If you generally use constructor-injection and don't want to switch to property-injection then Spring's lookup-method-injection will let one bean lazily lookup the other and hence workaround the cyclic dependency. See here: http://docs.spring.io/spring/docs/1.2.9/reference/beans.html#d0e1161

When using an iframe, you will first have to switch to the iframe, before selecting the elements of that iframe

You can do it using:

driver.switchTo().frame(driver.findElement(By.id("frameId")));
//do your stuff
driver.switchTo().defaultContent();

In case if your frameId is dynamic, and you only have one iframe, you can use something like:

driver.switchTo().frame(driver.findElement(By.tagName("iframe")));

Use this manual http://blog.antoine.li/2010/10/22/android-trusting-ssl-certificates/ This guide really helped me. It is important to observe a sequence of certificates in the store. For example: import the lowermost Intermediate CA certificate first and then all the way up to the Root CA certificate.

Edit: you should now use brew services start mongodb, as in Gergo's answer...

When you install/upgrade mongodb, brew will tell you what to do:

To have launchd start mongodb at login:

    ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

Then to load mongodb now:

    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

Or, if you don't want/need launchctl, you can just run:

    mongod

It works perfectly.

In regards to Python optimization, in addition to using PyPy (for pretty impressive speed-ups with zero change to your code), you could use PyPy's translation toolchain to compile an RPython-compliant version, or Cython to build an extension module, both of which are faster than the C version in my testing, with the Cython module nearly twice as fast. For reference I include C and PyPy benchmark results as well:

The RPython version has a couple of key changes. To translate into a standalone program you need to define your target, which in this case is the main function. It's expected to accept sys.argv as it's only argument, and is required to return an int. You can translate it by using translate.py, % translate.py euler12-rpython.py which translates to C and compiles it for you.

# euler12-rpython.py

import math, sys

def factorCount(n):
    square = math.sqrt(n)
    isquare = int(square)
    count = -1 if isquare == square else 0
    for candidate in xrange(1, isquare + 1):
        if not n % candidate: count += 2
    return count

def main(argv):
    triangle = 1
    index = 1
    while factorCount(triangle) < 1001:
        index += 1
        triangle += index
    print triangle
    return 0

if __name__ == '__main__':
    main(sys.argv)

def target(*args):
    return main, None

The Cython version was rewritten as an extension module _euler12.pyx, which I import and call from a normal python file. The _euler12.pyx is essentially the same as your version, with some additional static type declarations. The setup.py has the normal boilerplate to build the extension, using python setup.py build_ext --inplace.

# _euler12.pyx
from libc.math cimport sqrt

cdef int factorCount(int n):
    cdef int candidate, isquare, count
    cdef double square
    square = sqrt(n)
    isquare = int(square)
    count = -1 if isquare == square else 0
    for candidate in range(1, isquare + 1):
        if not n % candidate: count += 2
    return count

cpdef main():
    cdef int triangle = 1, index = 1
    while factorCount(triangle) < 1001:
        index += 1
        triangle += index
    print triangle

# euler12-cython.py
import _euler12
_euler12.main()

# setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext

ext_modules = [Extension("_euler12", ["_euler12.pyx"])]

setup(
  name = 'Euler12-Cython',
  cmdclass = {'build_ext': build_ext},
  ext_modules = ext_modules
)

I honestly have very little experience with either RPython or Cython, and was pleasantly surprised at the results. If you are using CPython, writing your CPU-intensive bits of code in a Cython extension module seems like a really easy way to optimize your program.

use the get method in the url. If you want to pass over a variable called 'phone' as 0001112222:

<a href='whatever.php?phone=0001112222'>click</a>

then on the next page (whatever.php) you can access this var via:

$_GET['phone']

"Where should I copy ICSharpCode.SharpZipLib.dll to see that namespace in Visual Studio?"

You need to add the dll file as a reference in your project. Right click on References in the Solution Explorer->Add Reference->Browse and then select the dll.

Finally you'll need to add it as a using statement in whatever files you want to use it in.

Here's a short and ugly way to do search file names using the AWS CLI:

aws s3 ls s3://your-bucket --recursive | grep your-search | cut -c 32-

You can try SharpZipLib for that. Is is open source, platform independent pure c# code.

A pipe takes in data as input and transforms it to a desired output. Add this pipe file:orderby.ts inside your /app folder .

orderby.ts

//The pipe class implements the PipeTransform interface's transform method that accepts an input value and an optional array of parameters and returns the transformed value.

import { Pipe,PipeTransform } from "angular2/core";

//We tell Angular that this is a pipe by applying the @Pipe decorator which we import from the core Angular library.

@Pipe({

  //The @Pipe decorator takes an object with a name property whose value is the pipe name that we'll use within a template expression. It must be a valid JavaScript identifier. Our pipe's name is orderby.

  name: "orderby"
})

export class OrderByPipe implements PipeTransform {
  transform(array:Array<any>, args?) {

    // Check if array exists, in this case array contains articles and args is an array that has 1 element : !id

    if(array) {

      // get the first element

      let orderByValue = args[0]
      let byVal = 1

      // check if exclamation point 

      if(orderByValue.charAt(0) == "!") {

        // reverse the array

        byVal = -1
        orderByValue = orderByValue.substring(1)
      }
      console.log("byVal",byVal);
      console.log("orderByValue",orderByValue);

      array.sort((a: any, b: any) => {
        if(a[orderByValue] < b[orderByValue]) {
          return -1*byVal;
        } else if (a[orderByValue] > b[orderByValue]) {
          return 1*byVal;
        } else {
          return 0;
        }
      });
      return array;
    }
    //
  }
}

In your component file (app.component.ts) import the pipe that you just added using: import {OrderByPipe} from './orderby';

Then, add *ngFor="#article of articles | orderby:'id'" inside your template if you want to sort your articles by id in ascending order or orderby:'!id'" in descending order.

We add parameters to a pipe by following the pipe name with a colon ( : ) and then the parameter value

We must list our pipe in the pipes array of the @Component decorator. pipes: [ OrderByPipe ] .

app.component.ts

import {Component, OnInit} from 'angular2/core';
import {OrderByPipe} from './orderby';

@Component({
    selector: 'my-app',
    template: `
      <h2>orderby-pipe by N2B</h2>
      <p *ngFor="#article of articles | orderby:'id'">
        Article title : {{article.title}}
      </p>
    `,
    pipes: [ OrderByPipe ]

})
export class AppComponent{
    articles:Array<any>
    ngOnInit(){
        this.articles = [
        {
            id: 1,
            title: "title1"
        },{
            id: 2,
            title: "title2",
        }]  
    }

}

define('SECONDS_PER_DAY', 86400);
$days_ago = date('Y-m-d', time() - 5 * SECONDS_PER_DAY);

Other than that, you can use strtotime for any date:

$days_ago = date('Y-m-d', strtotime('January 18, 2034') - 5 * SECONDS_PER_DAY);

Or, as you used, mktime:

$days_ago = date('Y-m-d', mktime(0, 0, 0, 12, 2, 2008) - 5 * SECONDS_PER_DAY);

Well, you get it. The key is to remove enough seconds from the timestamp.

If that <p> tag is created from JavaScript, then you do have another option: use JSS to programmatically insert stylesheets into the document head. It does support '&:hover'. https://cssinjs.org/

Use column command:

column -t -s' ' filename

This is just a suggestion, but what I like to do while I'm coding sometimes is to Invert the colors of my Screen. On a Mac it's Ctrl-Cmd-Alt->8 and it inverts the colors.

Haven't personally tried these in Idea10, but it worked on Idea9. http://devnet.jetbrains.net/docs/DOC-1154

like:

$('#Create .myClass, #Edit .myClass').plugin({ 
    options: here
});

You can specify any number of selectors to combine into a single result. This multiple expression combinator is an efficient way to select disparate elements. The order of the DOM elements in the returned jQuery object may not be identical, as they will be in document order. An alternative to this combinator is the .add() method.

• Multiple Selector
• Add method

For windows, @shoaly parameters didn't completely work for me. I was getting this error:

NCAT DEBUG: Proxy returned status code 501.
Ncat: Proxy returned status code 501.
ssh_exchange_identification: Connection closed by remote host

I wanted to ssh to a REMOTESERVER and the SSH port had been closed in my network. I found two solutions but the second is better.

• To solve the problem using Ncat:

  1. I downloaded Tor Browser, run and wait to connect.
  2. I got Ncat from Nmap distribution and extracted ncat.exe into the current directory.

  3. SSH using Ncat as ProxyCommand in Git Bash with addition --proxy-type socks4 parameter:

     ssh -o "ProxyCommand=./ncat --proxy-type socks4 --proxy 127.0.0.1:9150 %h %p" USERNAME@REMOTESERVER
     

     Note that this implementation of Ncat does not support socks5.

• THE BETTER SOLUTION:

  1. Do the previous step 1.

  2. SSH using connect.c as ProxyCommand in Git Bash:

     ssh -o "ProxyCommand=connect -a none -S 127.0.0.1:9150 %h %p"
     

     Note that connect.c supports socks version 4/4a/5.

To use the proxy in git commands using ssh (for example while using GitHub) -- assuming you installed Git Bash in C:\Program Files\Git\ -- open ~/.ssh/config and add this entry:

host github.com
    user git
    hostname github.com
    port 22
    proxycommand "/c/Program Files/Git/mingw64/bin/connect.exe" -a none -S 127.0.0.1:9150 %h %p

You could have an array that starts out with 10 elements. Read input character by character. If it goes over, realloc another 5 more. Not the best, but then you can free the other space later.

You can give the background image in css :

#canvas { background:url(example.jpg) }

it will show you canvas back ground image

In addition to the answer, $ yarn cache clean removes all libraries from cache. If you want to remove a specific lib's cache run $ yarn cache dir to get the right yarn cache directory path for your OS, then $ cd to that directory and remove the folder with the name + version of the lib you want to cleanup.

This one seems more pythonic to me:

>>> def clip(val, min_, max_):
...     return min_ if val < min_ else max_ if val > max_ else val

A few tests:

>>> clip(5, 2, 7)
5
>>> clip(1, 2, 7)
2
>>> clip(8, 2, 7)
7

argmax() will only return the first occurrence for each row. http://docs.scipy.org/doc/numpy/reference/generated/numpy.argmax.html

If you ever need to do this for a shaped array, this works better than unravel:

import numpy as np
a = np.array([[1,2,3], [4,3,1]])  # Can be of any shape
indices = np.where(a == a.max())

You can also change your conditions:

indices = np.where(a >= 1.5)

The above gives you results in the form that you asked for. Alternatively, you can convert to a list of x,y coordinates by:

x_y_coords =  zip(indices[0], indices[1])

As an aside to what folks have been posting here, I've heard that concatenation can be much faster than join in modern javascript vms. Meaning:

var a = 
[ "hey man, this is on a line",
  "and this is on another",
  "and this is on a third"
].join('\n');

Will be slower than:

var a = "hey man, this is on a line\n" + 
        "and this is on another\n" +
        "and this is on a third";    

In certain cases. http://jsperf.com/string-concat-versus-array-join/3

As another aside, I find this one of the more appealing features in Coffeescript. Yes, yes, I know, haters gonna hate.

html = '''
       <strong>
         cup of coffeescript
       </strong>
       '''

Its especially nice for html snippets. I'm not saying its a reason to use it, but I do wish it would land in ecma land :-(.

    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();

The ViewModel:

public class ViewModelBase

    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));

            return true/false;
        }
     }

    public void MyAction()

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

Thanks to Alloush,

Following parameter must be included in model.fit():

validation_data = (x_test, y_test)

If it is not defined, val_acc and val_loss will not be exist at output.

Load it like this

$this->load->library('../controllers/instructor');

and call the following method:

$this->instructor->functioname()

This works for CodeIgniter 2.x.

There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:

split(string str, string pat)
   Split str around pat (pat is a regular expression) 

In your case, the delimiter "|" has a special meaning as a regular expression, so it should be referred to as "\\|".

jQuery("select#cboDays option[value='Wednesday']").attr("selected", "selected");

First option is definitely the best option.

SELECT * FROM TABLE WHERE ID IN (id1, id2, ..., idn)

However considering that the list of ids is very huge, say millions, you should consider chunk sizes like below:

• Divide you list of Ids into chunks of fixed number, say 100
• Chunk size should be decided based upon the memory size of your server
• Suppose you have 10000 Ids, you will have 10000/100 = 100 chunks
• Process one chunk at a time resulting in 100 database calls for select

Why should you divide into chunks?

You will never get memory overflow exception which is very common in scenarios like yours. You will have optimized number of database calls resulting in better performance.

It has always worked like charm for me. Hope it would work for my fellow developers as well :)

[A-Za-z0-9_.-]*

This will also match for empty strings, if you do not want that exchange the last * for an +

Use , as format specifier:

>>> format(10000.21, ',')
'10,000.21'

Alternatively you can also use str.format instead of format:

>>> '{:,}'.format(10000.21)
'10,000.21'

With matplotlib.ticker.FuncFormatter:

...
ax.get_xaxis().set_major_formatter(
    matplotlib.ticker.FuncFormatter(lambda x, p: format(int(x), ',')))
ax2.get_xaxis().set_major_formatter(
    matplotlib.ticker.FuncFormatter(lambda x, p: format(int(x), ',')))

Create a ViewController with the UITableViewDelegate and UITableViewDataSource protocols. Then create a tableView inside it, declaring its style to be UITableViewStyle.grouped. This will fix the headers.

lazy var tableView: UITableView = {
    let view = UITableView(frame: UIScreen.main.bounds, style: UITableViewStyle.grouped)
    view.delegate = self
    view.dataSource = self
    view.separatorStyle = .none
    return view
}()

If you create a web based application, the better solution is to check the directory exists or not then create the file if not exist. If exists, recreate again.

    private File createFile(String path, String fileName) throws IOException {
       ClassLoader classLoader = getClass().getClassLoader();
       File file = new File(classLoader.getResource(".").getFile() + path + fileName);

       // Lets create the directory
       try {
          file.getParentFile().mkdir();
       } catch (Exception err){
           System.out.println("ERROR (Directory Create)" + err.getMessage());
       }

       // Lets create the file if we have credential
       try {
           file.createNewFile();
       } catch (Exception err){
           System.out.println("ERROR (File Create)" + err.getMessage());
       }
       return  file;
   }

"location" : null // this is not really an array it's a null object
"location" : []   // this is an empty array

It looks like this API returns null when there is no location defined - instead of returning an empty array, not too unusual really - but they should tell you if they're going to do this.

scanf() and friends return the number of input items successfully matched. For your code, that would be two or less (in case of less matches than specified). In short, be a little more careful with the manual pages:

#include <stdio.h>
#include <errno.h>
#include <stdbool.h>

int main(void)
{
    char item[9], status;

    FILE *fp;

    if((fp = fopen("D:\\Sample\\database.txt", "r+")) == NULL) {
        printf("No such file\n");
        exit(1);
    }

    while (true) {
        int ret = fscanf(fp, "%s %c", item, &status);
        if(ret == 2)
            printf("\n%s \t %c", item, status);
        else if(errno != 0) {
            perror("scanf:");
            break;
        } else if(ret == EOF) {
            break;
        } else {
            printf("No match.\n");
        }
    }
    printf("\n");
    if(feof(fp)) {
        puts("EOF");
    }
    return 0;
}

Try this:

UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:view.bounds];
view.layer.masksToBounds = NO;
view.layer.shadowColor = [UIColor blackColor].CGColor;
view.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);
view.layer.shadowOpacity = 0.5f;
view.layer.shadowPath = shadowPath.CGPath;

First of all: The UIBezierPath used as shadowPath is crucial. If you don't use it, you might not notice a difference at first, but the keen eye will observe a certain lag occurring during events like rotating the device and/or similar. It's an important performance tweak.

Regarding your issue specifically: The important line is view.layer.masksToBounds = NO. It disables the clipping of the view's layer's sublayers that extend further than the view's bounds.

For those wondering what the difference between masksToBounds (on the layer) and the view's own clipToBounds property is: There isn't really any. Toggling one will have an effect on the other. Just a different level of abstraction.

Swift 2.2:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.blackColor().CGColor
    layer.shadowOffset = CGSizeMake(0.0, 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.CGPath
}

Swift 3:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.black.cgColor
    layer.shadowOffset = CGSize(width: 0.0, height: 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.cgPath
}

All that's needed is: Start a new query and run:

SET SQL_SAFE_UPDATES = 0;

Then: Run the query that you were trying to run that wasn't previously working.

Here is my answer in Python 2.7

Print current time with timezone

from datetime import datetime
import tzlocal  # pip install tzlocal

print datetime.now(tzlocal.get_localzone()).strftime("%Y-%m-%d %H:%M:%S %z")

Print current time with specific timezone

from datetime import datetime
import pytz # pip install pytz

print datetime.now(pytz.timezone('Asia/Taipei')).strftime("%Y-%m-%d %H:%M:%S %z")

It will print something like

2017-08-10 20:46:24 +0800

A CRLF is two characters, of course, the CR and the LF. However, `n consists of both. For example:

PS C:\> $x = "Hello
>> World"

PS C:\> $x
Hello
World
PS C:\> $x.contains("`n")
True
PS C:\> $x.contains("`r")
False
PS C:\> $x.replace("o`nW","o There`nThe W")
Hello There
The World
PS C:\>

I think you're running into problems with the `r. I was able to remove the `r from your example, use only `n, and it worked. Of course, I don't know exactly how you generated the original string so I don't know what's in there.

I recommend GPick:

sudo apt-get install gpick

Applications -> Graphics -> GPick

It has many more features than gcolor2 but is still extremely simple to use: click on one of the hex swatches, move your mouse around the screen over the colours you want to pick, then press the Space bar to add to your swatch list.

If that doesn't work, another way is to click-and-drag from the centre of the hexagon and release your mouse over the pixel that you want to sample. Then immediately hit Space to copy that color into the next swatch in rotation.

It also has a traditional colour picker (like gcolor2) in the bottom right-hand corner of the window to allow you to pick individual colours with magnification.

Supopose you want to copy oldList into a new ArrayList object called newList

ArrayList<Object> newList = new ArrayList<>() ;

for (int i = 0 ; i<oldList.size();i++){
    newList.add(oldList.get(i)) ;
}

These two lists are indepedant, changes to one are not reflected to the other one.

If you have already defined your view in layout(xml) file and only want to change the weight pro grammatically, then then creating new LayoutParams overwrites other params defined in you xml file.

So first you should use "getLayoutParams" and then setLayoutParams

LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) mButton.getLayoutParams(); params.weight = 4f; mButton.setLayoutParams(params);

Looking at your example, I think this is what you want:

var dict = TableObj.ToDictionary(t => t.Key, t=> t.TimeStamp);

If you use spring-boot, you don't need to create a DataSource class, just specify the data url/username/password/driver in application.properties, then you can simply @Autowired it.

@Repository
public class JdbcRepository {

    private final JdbcTemplate jdbcTemplate;

    @Autowired
    public DynamicRepository(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    public void insert() {
        jdbcTemplate.update("INSERT INTO BOOK (name, description) VALUES ('book name', 'book description')");
    }
}

Example of application.properties:

#Basic Spring Boot Config for Oracle
spring.datasource.url=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=YourHostIP)(PORT=YourPort))(CONNECT_DATA=(SERVER=dedicated)(SERVICE_NAME=YourServiceName)))
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

#hibernate config
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect

Then add the driver and connection pool dependencies in pom.xml

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.1</version>
</dependency>

<!-- HikariCP connection pool -->
<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
    <version>2.6.0</version>
</dependency>

}

$_SESSION['last-activity'] = time(); // update last activity time stamp

if(time() - $_SESSION['created'] > 600) {

You must set the bounds properties to fit that frame. frame its superview properties, and bounds limit the frame in the view itself coordinate system.

In addition to the other answers using HTML (either in Markdown or using the %%HTML magic:

If you need to specify the image height, this will not work:

<img src="image.png" height=50> <-- will not work

That is because the CSS styling in Jupyter uses height: auto per default for the img tags, which overrides the HTML height attribute. You need need to overwrite the CSS height attribute instead:

<img src="image.png" style="height:50px"> <-- works

You need to know the chunk size by which you're dividing your list. Say you have a list of 108 entries and you need a chunk size of 25. Thus you will end up with 5 lists:

• 4 having 25 entries each;
• 1 (the fifth) having 8 elements.

Code:

public static void main(String[] args) {

        List<Integer> list = new ArrayList<Integer>();
        for (int i=0; i<108; i++){
            list.add(i);
        }
        int size= list.size();
        int j=0;
                List< List<Integer> > splittedList = new ArrayList<List<Integer>>()  ;
                List<Integer> tempList = new ArrayList<Integer>();
        for(j=0;j<size;j++){
            tempList.add(list.get(j));
        if((j+1)%25==0){
            // chunk of 25 created and clearing tempList
            splittedList.add(tempList);
            tempList = null;
            //intializing it again for new chunk 
            tempList = new ArrayList<Integer>();
        }
        }
        if(size%25!=0){
            //adding the remaining enteries 
            splittedList.add(tempList);
        }
        for (int k=0;k<splittedList.size(); k++){
            //(k+1) because we started from k=0
            System.out.println("Chunk number: "+(k+1)+" has elements = "+splittedList.get(k).size());
        }
    }

With an example of the not-working code, it will be easy to answer this question, but with this information the best that I can think is that you are calling the $location.path outside of the AngularJS digest.

Try doing this on the directive scope.$apply(function() { $location.path("/route"); });

You can use my highlight script from https://github.com/kepkin/dev-shell-essentials

It's better than grep because you can highlight each match with its own color.

$ command_here | highlight green "input" | highlight red "output"

I just had this issue and realized that there were empty columns being treated as columns with values, I saw this by opening my CSV in my text editor. To fix this, I opened my spreadsheet and deleted the columns after my last column, they looked completely empty but they were not. After I did this, the import worked perfectly.

I know this question is about C, but the same question for C++ was closed as a exact duplicate of this question. This answer therefore may not apply for C.

The latest draft of the C++11 standard, N3485, says this in 7.1.1/3:

A register specifier is a hint to the implementation that the variable so declared will be heavily used. [ note: The hint can be ignored and in most implementations it will be ignored if the address of the variable is taken. This use is deprecated ... —end note ]

In C++ (but not in C), the standard does not state that you can't take the address of a variable declared register; however, because a variable stored in a CPU register throughout its lifetime does not have a memory location associated with it, attempting to take its address would be invalid, and the compiler will ignore the register keyword to allow taking the address.

hostName == null;
Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
{
    while (interfaces.hasMoreElements()) {
        NetworkInterface nic = interfaces.nextElement();
        Enumeration<InetAddress> addresses = nic.getInetAddresses();
        while (hostName == null && addresses.hasMoreElements()) {
            InetAddress address = addresses.nextElement();
            if (!address.isLoopbackAddress()) {
                hostName = address.getHostName();
            }
        }
    }
}

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

Include the class that you are using Within your text file, then intelliSense will know where to look when you type within your text file. This works for me.

So it’s important to check the Unreal API to see where the included class is so that you have the path to type on the include line. Hope that makes sense.

This is what fixed it for me:

max-height: 100%;
overflow-y: auto;

EDIT: I now use the same method currently used on Twitter where the modal acts sort of like a separate page on top of the current content and the content behind the modal does not move as you scroll.

In essence it is this:

var scrollBarWidth = window.innerWidth - document.body.offsetWidth;
$('body').css({
  marginRight: scrollBarWidth,
  overflow: 'hidden'
});
$modal.show();

With this CSS on the modal:

position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
overflow: auto;

JSFiddle: https://jsfiddle.net/0x0049/koodkcng/
Pure JS version (IE9+): https://jsfiddle.net/0x0049/koodkcng/1/

This works no matter the height or width of the page or modal dialog, allows scrolling no matter where your mouse/finger is, doesn't have the jarring jump some solutions have that disable scroll on the main content, and looks great too.

I had the same problem with "document.cookie" in Windows 8.1, the only way that Chrome deletes the cookie was shutting it from task manager (not a really fancy way), so I decided to manage the cookies from the backend or use something like "js-cookie".

There are several methods, two of which are as follows. Provide a custom installer or a setup project.

Here is how to create a custom installer

[RunInstaller(true)]
public class MyInstaller : Installer
{
    public HelloInstaller()
        : base()
    {
    }

    public override void Commit(IDictionary mySavedState)
    {
        base.Commit(mySavedState);
        System.IO.File.CreateText("Commit.txt");
    }

    public override void Install(IDictionary stateSaver)
    {
        base.Install(stateSaver);
        System.IO.File.CreateText("Install.txt");
    }

    public override void Uninstall(IDictionary savedState)
    {
        base.Uninstall(savedState);
        File.Delete("Commit.txt");
        File.Delete("Install.txt");
    }

    public override void Rollback(IDictionary savedState)
    {
        base.Rollback(savedState);
        File.Delete("Install.txt");
    }
}

To add a setup project

• Menu file -> New -> Project --> Other Projects Types --> Setup and Deployment

• Set properties of the project, using the properties window

The article How to create a Setup package by using Visual Studio .NET provides the details.

As said, the browser doesn't let the server know when it closes.

Still, there are some ways to achieve close to this behavior. You can put a small AJAX script in place that updates the server regularly that the browser is open. You should pair this with something that fires on actions made by the user, so you can time out an idle session as well as one that has closed out.

I would use python-dpkt. Here is the documentation: http://www.commercialventvac.com/dpkt.html

This is all I know how to do though sorry.

for ts, pkt in dpkt.pcap.Reader(open(filename,'r')):

    eth=dpkt.ethernet.Ethernet(pkt) 
    if eth.type!=dpkt.ethernet.ETH_TYPE_IP:
       continue

    ip=eth.data
    ipcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_TCP: 
       tcpcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_UDP:
       udpcounter+=1

print "Total number of packets in the pcap file: ", counter
print "Total number of ip packets: ", ipcounter
print "Total number of tcp packets: ", tcpcounter
print "Total number of udp packets: ", udpcounter

type C:\temp\test.bat>C:\temp\test.log

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

At original time of writing to uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

I don't think this has been mentioned. This is like your own answer but I think it's even simpler. You can always return strings from the expressions and you can nest jsx inside expressions, so this allows for an easy to read inline expression.

render: function () {
    return (
        <div id="page">
            {this.state.banner ? <div id="banner">{this.state.banner}</div> : ''}
            <div id="other-content">
                blah blah blah...
            </div>
        </div>
    );
}

SwiftRichString works perfect! You can use + to concatenate two attributed string

There are ways of executing tests in a given order. Normally though, tests have to be repeatable and independent to guarantee it is testing only the desired functionality and is not dependent on side effects of code outside of what is being tested.

So, to answer your question, you'll need to provide more information such as WHY it is important to run tests in a specific order.

//slightly improved code without using collection framework

package com.test;

public class TestClass {

    private static Link last;
    private static Link first;

    public static void main(String[] args) {

        //Inserting
        for(int i=0;i<5;i++){
            Link.insert(i+5);
        }
        Link.printList();

        //Deleting
        Link.deletefromFirst();
        Link.printList();
    }


    protected  static class Link {
        private int data;
        private Link nextlink;

        public Link(int d1) {
            this.data = d1;
        }

        public static void insert(int d1) {
            Link a = new Link(d1);
            a.nextlink = null;
            if (first != null) {
                last.nextlink = a;
                last = a;
            } else {
                first = a;
                last = a;
            }
            System.out.println("Inserted -:"+d1);
        }

        public static void deletefromFirst() {
            if(null!=first)
            {
                System.out.println("Deleting -:"+first.data);
                first = first.nextlink;
            }
            else{
                System.out.println("No elements in Linked List");
            }
        }

        public static void printList() {
            System.out.println("Elements in the list are");
            System.out.println("-------------------------");
            Link temp = first;
            while (temp != null) {
                System.out.println(temp.data);
                temp = temp.nextlink;
            }
        }
    }
}

There are a few places you can do versioning in a REST API:

1. As noted, in the URI. This can be tractable and even esthetically pleasing if redirects and the like are used well.

2. In the Accepts: header, so the version is in the filetype. Like 'mp3' vs 'mp4'. This will also work, though IMO it works a bit less nicely than...

3. In the resource itself. Many file formats have their version numbers embedded in them, typically in the header; this allows newer software to 'just work' by understanding all existing versions of the filetype while older software can punt if an unsupported (newer) version is specified. In the context of a REST API, it means that your URIs never have to change, just your response to the particular version of data you were handed.

I can see reasons to use all three approaches:

1. if you like doing 'clean sweep' new APIs, or for major version changes where you want such an approach.
2. if you want the client to know before it does a PUT/POST whether it's going to work or not.
3. if it's okay if the client has to do its PUT/POST to find out if it's going to work.

I can't remember where I found this solution, but I find it to be the most 'elegant' from my non-Python-expert point of view:

class SomeSingleton(dict):
    __instance__ = None
    def __new__(cls, *args,**kwargs):
        if SomeSingleton.__instance__ is None:
            SomeSingleton.__instance__ = dict.__new__(cls)
        return SomeSingleton.__instance__

    def __init__(self):
        pass

    def some_func(self,arg):
        pass

Why do I like this? No decorators, no meta classes, no multiple inheritance...and if you decide you don't want it to be a Singleton anymore, just delete the __new__ method. As I am new to Python (and OOP in general) I expect someone will set me straight about why this is a terrible approach?

I created a project to easily initiate a project skeleton from scratch. https://github.com/MacHu-GWU/pygitrepo-project.

And you can create a test project, let's say, learn_creating_py_package.

You can learn what component you should have for different purpose like:

• create virtualenv
• install itself
• run unittest
• run code coverage
• build document
• deploy document
• run unittest in different python version
• deploy to PYPI

The advantage of using pygitrepo is that those tedious are automatically created itself and adapt your package_name, project_name, github_account, document host service, windows or macos or linux.

It is a good place to learn develop a python project like a pro.

Hope this could help.

Thank you.

parseDouble() method is used to initialise a STRING (which should contains some numerical value)....the value it returns is of primitive data type, like int, float, etc.

But valueOf() creates an object of Wrapper class. You have to unwrap it in order to get the double value. It can be compared with a chocolate. The manufacturer wraps the chocolate with some foil or paper to prevent from pollution. The user takes the chocolate, removes and throws the wrapper and eats it.

Observe the following conversion.

int k = 100; Integer it1 = new Integer(k);

The int data type k is converted into an object, it1 using Integer class. The it1 object can be used in Java programming wherever k is required an object.

The following code can be used to unwrap (getting back int from Integer object) the object it1.

int m = it1.intValue();

System.out.println(m*m); // prints 10000

//intValue() is a method of Integer class that returns an int data type.

Normally, the error will occur due to an unsuitable AVD emulator for the type of app you are developing for. For example if you are developing an app for a wearable but you are trying to use a phone emulator to run it.

string s2 = s1.Replace(",", "," + Environment.NewLine);

Also, just from a performance perspective, here's how the three current solutions I've seen stack up over 100k iterations:

ReplaceWithConstant           - Ms: 328, Ticks: 810908
ReplaceWithEnvironmentNewLine - Ms: 310, Ticks: 766955 
SplitJoin                     - Ms: 483, Ticks: 1192545

ReplaceWithConstant:

string s2 = s1.Replace(",", ",\n");

ReplaceWithEnvironmentNewLine:

string s2 = s1.Replace(",", "," + Environment.NewLine);

SplitJoin:

string s2 = String.Join("," + Environment.NewLine, s1.Split(','));

ReplaceWithEnvironmentNewLine and ReplaceWithConstant are within the margin of error of each other, so there's functionally no difference.

Using Environment.NewLine should be preferred over "\n" for the sake readability and consistency similar to using String.Empty instead of "".

XOR is a binary operation, it stands for "exclusive or", that is to say the resulting bit evaluates to one if only exactly one of the bits is set.

This is its function table:

a | b | a ^ b
--|---|------
0 | 0 | 0
0 | 1 | 1
1 | 0 | 1
1 | 1 | 0

This operation is performed between every two corresponding bits of a number.

Example: 7 ^ 10
In binary: 0111 ^ 1010

  0111
^ 1010
======
  1101 = 13

Properties: The operation is commutative, associative and self-inverse.

It is also the same as addition modulo 2.

#include <iostream>
#include <cstdlib>
#include <ctime>

int main() {
    srand(time(NULL));
    int random_number = std::rand(); // rand() return a number between ?0? and RAND_MAX
    std::cout << random_number;
    return 0;
}

You can access this by

Right click on instance (IE SQLServer2008)
Select "Properties"
Select "Security" option
Change "Server authentication" to "SQL Server and Windows Authentication mode"
Restart the SQLServer service
    Right click on instance
    Click "Restart"

Just for anyone else reading this: This worked for me on 2012 SQL Server too. Thanks

At the time you emit the very first line,

to achieve "alignment", you have to know "in advance" how wide each column will need to be (otherwise, alignment is impossible). Once you do know the needed width for each column (there are several possible ways to achieve that depending on where your data's coming from), then the setw function mentioned in the other answer will help, or (more brutally;-) you could emit carefully computed number of extra spaces (clunky, to be sure), etc. I don't recommend tabs anyway as you have no real control on how the final output device will render those, in general.

Back to the core issue, if you have each column's value in a vector<T> of some sort, for example, you can do a first formatting pass to determine the maximum width of the column, for example (be sure to take into account the width of the header for the column, too, of course).

If your rows are coming "one by one", and alignment is crucial, you'll have to cache or buffer the rows as they come in (in memory if they fit, otherwise on a disk file that you'll later "rewind" and re-read from the start), taking care to keep updated the vector of "maximum widths of each column" as the rows do come. You can't output anything (not even the headers!), if keeping alignment is crucial, until you've seen the very last row (unless you somehow magically have previous knowledge of the columns' widths, of course;-).

There is a much simpler way. This does not care if it is binary or text file.

Use noskipws.

char buf[SZ];
ifstream f("file");
int i;
for(i=0; f >> noskipws >> buffer[i]; i++);
ofstream f2("writeto");
for(int j=0; j < i; j++) f2 << noskipws << buffer[j];

Or you can just use string instead of the buffer.

string s; char c;
ifstream f("image.jpg");
while(f >> noskipws >> c) s += c;
ofstream f2("copy.jpg");
f2 << s;

normally stream skips white space characters like space or new line, tab and all other control characters. But noskipws makes all the characters transferred. So this will not only copy a text file but also a binary file. And stream uses buffer internally, I assume the speed won't be slow.

The following MySQL statement should modify your column to accept NULLs.

ALTER TABLE `MyTable`
ALTER COLUMN `Col3` varchar(20) DEFAULT NULL

Thanks to a comment by zerkms, I was able to notice my stupid mistake:

I had onItemClick(e, item) when I should have had onItemClick(item, e).

changing name of /bootstrap/cache/config.php to config.php.old doesn't work for me neither clearing cache with the commands artisan

1. php artisan config:clear
2. php artisan cache:clear
3. php artisan config:cache

And for some weird reason I can't change permission for the owner on the directories, so my solution was running my IDE (Visual Studio Code) as admin, and everything works.

My project is in an F:/ path of another disk.
