I'm still experiencing this behavior with jQuery 1.7.2. A simple workaround is to defer the execution of the click handler with setTimeout and let the browser do its magic in the meantime:

$("#myCheckbox").click( function() {
    var that = this;
    setTimeout(function(){
        alert($(that).is(":checked"));
    });
});

You can change from the "build.gradle" file the line:

compileSdkVersion 18

to the sdk that you want to be used.

you can use rowSums

rowSums(data) should give you what you want.

If you are using a SpringBoot application it's as simple as

ScheduledProcess

@Log
@Component
public class ScheduledProcess {

    @Scheduled(fixedRate = 5000)
    public void run() {
        log.info("this runs every 5 seconds..");
    }

}

Application.class

@SpringBootApplication
// ADD THIS ANNOTATION TO YOUR APPLICATION CLASS
@EnableScheduling
public class SchedulingTasksApplication {

    public static void main(String[] args) {
        SpringApplication.run(SchedulingTasksApplication.class);
    }
}

Avoid QT (for noobs) or any useless libraries (absurd for a such basic thing)

Just use the VS Win32 api Wizard, ad the button and text box...and that's all !

In 25 seconds !

Update your user, domain, and proxy information in cntlm.ini, then test your proxy with this command (run in your Cntlm installation folder):

cntlm -c cntlm.ini -I -M http://google.ro

It will ask for your password, and hopefully print your required authentication information, which must be saved in your cntlm.ini

Sample cntlm.ini:

Username            user
Domain              domain

# provide actual value if autodetection fails
# Workstation         pc-name

Proxy               my_proxy_server.com:80
NoProxy             127.0.0.*, 192.168.*

Listen              127.0.0.1:54321
Listen              192.168.1.42:8080
Gateway             no

SOCKS5Proxy         5000
# provide socks auth info if you want it
# SOCKS5User          socks-user:socks-password

# printed authentication info from the previous step
Auth            NTLMv2
PassNTLMv2      98D6986BCFA9886E41698C1686B58A09

Note: on linux the config file is cntlm.conf

It is kind of a hack but wrapping it in a timeout seems to accomplish what you are looking for:

angular.module('myApp', [])
    .controller('Ctrl', ['$scope', '$timeout', function ($scope, $timeout) {
    $scope.todos = [{
        'text': "get milk",
        'done': true
    }, {
        'text': "get milk2",
            'done': false
    }];

    $scope.onCompleteTodo = function (todo) {
        $timeout(function(){
            console.log("onCompleteTodo -done: " + todo.done + " : " + todo.text);
            $scope.doneAfterClick = todo.done;
            $scope.todoText = todo.text;
        });
    };
}]);

Well, I think checking the type of variable can be done this way.

public <T extends Object> void checkType(T object) {    
    if (object instanceof Integer)
        System.out.println("Integer ");
    else if(object instanceof Double)
        System.out.println("Double ");
    else if(object instanceof Float)
        System.out.println("Float : ");
    else if(object instanceof List)
        System.out.println("List! ");
    else if(object instanceof Set)
        System.out.println("Set! ");
}

This way you need not have multiple overloaded methods. I think it is good practice to use collections over arrays due to the added benefits. Having said that, I do not know how to check for an array type. Maybe someone can improve this solution. Hope this helps!

P.S Yes, I know that this doesn't check for primitives as well.

It's not officially supported yet.

Edit: It's now supported in modern versions of Android Studio, at least on some platforms.

Old workarounds

If you're using an old version of Android Studio which doesn't support the Google Play Store, and you refuse to upgrade, here are two possible workarounds:

1. Ask your favorite app's maintainers to upload a copy of their app into the Amazon Appstore. Next, install the Appstore onto your Android device. Finally, use the Appstore to install your favorite app.

2. Or: Do a Web search to find a .apk file for the software you want. For example, if you want to install SleepBot in your Android emulator, you can do a Google Web search for [ SleepBot apk ]. Then use adb install to install the .apk file.

or you can use this thing

$arr = [1,2,3];
$obj = json_decode(json_encode($arr));
print_r($obj);

$('#registerform').submit(function(e) {
   e.preventDefault();
   $.ajax({
        type: 'POST',
        url: 'submit.php',
        data: $(this).serialize(),
        beforeSend: //do something
        complete: //do something
        success: //do something for example if the request response is success play your animation...
   });

})

On Mac IntelliJ Idea 12 has it's preferences/keymaps placed here: ./Users/viliuskraujutis/Library/Preferences/IdeaIC12/keymaps/

Here is setting headers from github sample:

StringRequest myReq = new StringRequest(Method.POST,
                       "http://ave.bolyartech.com/params.php",
                        createMyReqSuccessListener(),
                        createMyReqErrorListener()) {

 protected Map<String, String> getParams() throws 
         com.android.volley.AuthFailureError {
                        Map<String, String> params = new HashMap<String, String>();
                        params.put("param1", num1);
                        params.put("param2", num2);
                        return params;
                    };
                };
                queue.add(myReq);

Very simple:

Use COUNT_BIG(*) AS NumStreams

If your timestamp includes time, not only date, use:

SELECT DATE_FORMAT('timestamp', '%Y-%m-%d') AS date, COUNT(id) AS count FROM table GROUP BY DATE_FORMAT('timestamp', '%Y-%m-%d')

If you want "Use Autolayout" to be enabled at any cost place the following code in viewdidload.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) 
{
        self.edgesForExtendedLayout = UIRectEdgeNone;
        self.extendedLayoutIncludesOpaqueBars = NO;
        self.automaticallyAdjustsScrollViewInsets = NO;
}

Here is a crude timing test to compare the two:

import java.util.Date;

public class EnumCompareSpeedTest {

    static enum TestEnum {ONE, TWO, THREE }

    public static void main(String [] args) {

        Date before = new Date();
        int c = 0;

        for(int y=0;y<5;++y) {
            for(int x=0;x<Integer.MAX_VALUE;++x) {
                if(TestEnum.ONE.equals(TestEnum.TWO)) {++c;}
                if(TestEnum.ONE == TestEnum.TWO){++c;}              
            }
        }

        System.out.println(new Date().getTime() - before.getTime());
    }   

}

Comment out the IFs one at a time. Here are the two compares from above in disassembled byte-code:

 21  getstatic EnumCompareSpeedTest$TestEnum.ONE : EnumCompareSpeedTest.TestEnum [19]
 24  getstatic EnumCompareSpeedTest$TestEnum.TWO : EnumCompareSpeedTest.TestEnum [25]
 27  invokevirtual EnumCompareSpeedTest$TestEnum.equals(java.lang.Object) : boolean [28]
 30  ifeq 36

 36  getstatic EnumCompareSpeedTest$TestEnum.ONE : EnumCompareSpeedTest.TestEnum [19]
 39  getstatic EnumCompareSpeedTest$TestEnum.TWO : EnumCompareSpeedTest.TestEnum [25]
 42  if_acmpne 48

The first (equals) performs a virtual call and tests the return boolean from the stack. The second (==) compares the object addresses directly from the stack. In the first case there is more activity.

I ran this test several times with both IFs one at a time. The "==" is ever so slightly faster.

Ahhh, that's super simple, no programming required.

You'll want to keep the show stream option turned on. You can adjust width and heigth and a few other things.

Unless I am misunderstanding, you can just add height: 100%; and overflow:hidden; to #down.

#down { 
    background:pink; 
    height:100%; 
    overflow:hidden;
}?

Live DEMO

Edit: Since you do not want to use overflow:hidden;, you can use display: table; for this scenario; however, it is not supported prior to IE 8. (display: table; support)

#container { 
    width: 300px; 
    height: 300px; 
    border:1px solid red;
    display:table;
}

#up { 
    background: green;
    display:table-row;
    height:0; 
}

#down { 
    background:pink;
    display:table-row;
}?

Live DEMO

Note: You have said that you want the #down height to be #container height minus #up height. The display:table; solution does exactly that and this jsfiddle will portray that pretty clearly.

1) HTML is downloaded.

2) HTML is parsed progressively. When a request for an asset is reached the browser will attempt to download the asset. A default configuration for most HTTP servers and most browsers is to process only two requests in parallel. IE can be reconfigured to downloaded an unlimited number of assets in parallel. Steve Souders has been able to download over 100 requests in parallel on IE. The exception is that script requests block parallel asset requests in IE. This is why it is highly suggested to put all JavaScript in external JavaScript files and put the request just prior to the closing body tag in the HTML.

3) Once the HTML is parsed the DOM is rendered. CSS is rendered in parallel to the rendering of the DOM in nearly all user agents. As a result it is strongly recommended to put all CSS code into external CSS files that are requested as high as possible in the <head></head> section of the document. Otherwise the page is rendered up to the occurance of the CSS request position in the DOM and then rendering starts over from the top.

4) Only after the DOM is completely rendered and requests for all assets in the page are either resolved or time out does JavaScript execute from the onload event. IE7, and I am not sure about IE8, does not time out assets quickly if an HTTP response is not received from the asset request. This means an asset requested by JavaScript inline to the page, that is JavaScript written into HTML tags that is not contained in a function, can prevent the execution of the onload event for hours. This problem can be triggered if such inline code exists in the page and fails to execute due to a namespace collision that causes a code crash.

Of the above steps the one that is most CPU intensive is the parsing of the DOM/CSS. If you want your page to be processed faster then write efficient CSS by eliminating redundent instructions and consolidating CSS instructions into the fewest possible element referrences. Reducing the number of nodes in your DOM tree will also produce faster rendering.

Keep in mind that each asset you request from your HTML or even from your CSS/JavaScript assets is requested with a separate HTTP header. This consumes bandwidth and requires processing per request. If you want to make your page load as fast as possible then reduce the number of HTTP requests and reduce the size of your HTML. You are not doing your user experience any favors by averaging page weight at 180k from HTML alone. Many developers subscribe to some fallacy that a user makes up their mind about the quality of content on the page in 6 nanoseconds and then purges the DNS query from his server and burns his computer if displeased, so instead they provide the most beautiful possible page at 250k of HTML. Keep your HTML short and sweet so that a user can load your pages faster. Nothing improves the user experience like a fast and responsive web page.

If you want something a little bit more readable, you can try this:

<button @click="[click1($event), click2($event)]">
  Multiple
</button>

To me, this solution feels more Vue-like hope you enjoy

You can reset your root password. Have in mind that it is not advisable to use root without password.

I wanted a way to do this without using an extra module. First turn list to string, then append to an array:

dataset_list = ''.join(input_list)
dataset_array = []
for item in dataset_list.split(';'): # comma, or other
    dataset_array.append(item)

Have you taken a look at underscore.js (http://underscorejs.org/docs/underscore.html)? It's a utility library with a lot of useful methods. There is a collection size method, as well as a toArray method, which may get you what you need.

_.size({one : 1, two : 2, three : 3});
=> 3

Here's another one:

$ { echo JBoss DOWN; echo GlassFish UP; } | while read PROC STATUS; do echo -n "$PROC "; printf "%$((48-${#PROC}))s " | tr ' ' -; echo " [$STATUS]"; done

Quick answer for single line span

Make the child (in this case a span) the same line-height as the parent <div>'s height

<div class="parent">
  <span class="child">Yes mom, I did my homework lol</span>
</div>

You should then add the CSS rules

.parent { height: 20px; }
.child { line-height: 20px; vertical-align: middle; }

Or you can target it with a child selector

.parent { height: 20px; }
.parent > span { line-height: 20px; vertical-align: middle; }

Background on my own use of this

I ran into this similar issue where I needed to vertically center items in a mobile menu. I made the div and spans inside the same line height. Note that this is for a meteor project and therefore not using inline css ;)

HTML

<div class="international">        
  <span class="intlFlag">
    {{flag}}        
  </span>

  <span class="intlCurrent">
    {{country}}
  </span>

  <span class="intlButton">
    <i class="fa fa-globe"></i>
  </span> 
</div>

CSS (option for multiple spans in a div)

.international {
  height: 42px;
}

.international > span {
  line-height: 42px;
}

In this case if I just had one span I could have added the CSS rule directly to that span.

CSS (option for one specific span)

.intlFlag { line-height: 42px; }

Here is how it displayed for me

I deleted the 20-mongo.ini file in /etc/php5/cli/conf.d and this solved the problem.

I generally prefer to add these codes in a function to get the Android version:

int whichAndroidVersion;

whichAndroidVersion= Build.VERSION.SDK_INT;
textView.setText("" + whichAndroidVersion); //If you don't use "" then app crashes.

For example, that code above will set the text into my textView as "29" now.

System.out.println("Element "+i+list.get(0));}

Should be

System.out.println("Element "+i+list.get(i));}

To use the JSF tags, you give the dataList value attribute a reference to your list of elements, and the var attribute is a local name for each element of that list in turn. Inside the dataList, you use properties of the object (getters) to output the information about that individual object:

<t:dataList id="myDataList" value="#{houseControlList}" var="element" rows="3" >
...
<t:outputText id="houseId" value="#{element.houseId}"/>
...
</t:dataList>

Although there is clearly some kind of network instability or something interfering with your connection (15 minutes is possible that you could be crossing a NAT boundary or something in your network is dropping the session), I would think you want such a simple?) query to return well within any anticipated timeoue (like 1s).

I would talk to your DBA and get an index created on the underlying tables on MemberType, Status. If there isn't a single underlying table or these are more complex and created by the view or UDF, and you are running SQL Server 2005 or above, have him consider indexing the view (basically materializing the view in an indexed fashion).

I had the same problem in Safari and Chrome (the only ones I've tested) but I just did something that seems to work, at least I haven't been able to reproduce the problem since I added the solution. What I did was add a metatag to the header with a generated timstamp. Doesn't seem right but it's simple :)

Update P.S As far as I can tell, the problem disappears when I remove my node proxy (by proxy i mean both express.vhost and http-proxy module), which is weird...

range() returns a list, xrange() returns an xrange object.

xrange() is a bit faster, and a bit more memory efficient. But the gain is not very large.

The extra memory used by a list is of course not just wasted, lists have more functionality (slice, repeat, insert, ...). Exact differences can be found in the documentation. There is no bonehard rule, use what is needed.

Python 3.0 is still in development, but IIRC range() will very similar to xrange() of 2.X and list(range()) can be used to generate lists.

public static void main(String[] args) 
{
    int i = 13;
    short s = 13;
    byte b = 13;

    System.out.println("i: " + String.format("%32s", 
            Integer.toBinaryString(i)).replaceAll(" ", "0"));

    System.out.println("s: " + String.format("%16s", 
            Integer.toBinaryString(0xFFFF & s)).replaceAll(" ", "0"));

    System.out.println("b: " + String.format("%8s", 
            Integer.toBinaryString(0xFF & b)).replaceAll(" ", "0"));

}

Output:

i: 00000000000000000000000000001101
s: 0000000000001101
b: 00001101

You can now accomplish this in Chrome by right clicking on the object and selecting "Store as Global Variable": http://www.youtube.com/watch?v=qALFiTlVWdg

>>> import string
>>> safechars = bytearray(('_-.()' + string.digits + string.ascii_letters).encode())
>>> allchars = bytearray(range(0x100))

>>> filename = u'#ab\xa0c.$%.txt'
>>> safe_filename = filename.encode('ascii', 'ignore').translate(None, deletechars).decode()
>>> safe_filename
'abc..txt'

It doesn't handle empty strings, special filenames ('nul', 'con', etc).

The comment left by tiho on Mar 27 '14 at 17:21 deserves to be its own answer:

In order to avoid platform-specific code, use timeit.default_timer()

Here is a complete example

#include <thread>
#include <iostream>

class Wrapper {
   public:
      void member1() {
          std::cout << "i am member1" << std::endl;
      }
      void member2(const char *arg1, unsigned arg2) {
          std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
      }
      std::thread member1Thread() {
          return std::thread([=] { member1(); });
      }
      std::thread member2Thread(const char *arg1, unsigned arg2) {
          return std::thread([=] { member2(arg1, arg2); });
      }
};
int main(int argc, char **argv) {
   Wrapper *w = new Wrapper();
   std::thread tw1 = w->member1Thread();
   std::thread tw2 = w->member2Thread("hello", 100);
   tw1.join();
   tw2.join();
   return 0;
}

Compiling with g++ produces the following result

g++ -Wall -std=c++11 hello.cc -o hello -pthread

i am member1
i am member2 and my first arg is (hello) and second arg is (100)

& is a keyword for the next parameter like this ur?param1=1&param2=2

so effectively you send a second param named R". You should urlencode your string. Isn't POST an option?

An TextInput must include secureTextEntry={true}, note that the docs of React state that you must not use multiline={true} at the same time, as that combination is not supported.

You can also set textContentType={'password'} to allow the field to retrieve credentials from the keychain stored on your mobile, an alternative way to enter credentials if you got biometric input on your mobile to quickly insert credentials. Such as FaceId on iPhone X or fingerprint touch input on other iPhone models and Android.

 <TextInput value={this.state.password} textContentType={'password'} multiline={false} secureTextEntry={true} onChangeText={(text) => { this._savePassword(text); this.setState({ password: text }); }} style={styles.input} placeholder='Github password' />

You can also declare 'x' with the keyword var:

var x = new
{
  driver = new
  {
    firstName = "john",
    lastName = "walter"
  },
  car = new
  {
    brand = "BMW"
  }
};

This will allow you to declare your x object inline, but you will have to name your 2 anonymous objects, in order to access them. You can have an array of "x" :

x.driver.firstName // "john"
x.car.brand // "BMW"

var y = new[] { x, x, x, x };
y[1].car.brand; // "BMW"

Using std::vector<unsigned char>:

#include <vector>
using namespace std;

vector<unsigned char> intToBytes(int paramInt)
{
     vector<unsigned char> arrayOfByte(4);
     for (int i = 0; i < 4; i++)
         arrayOfByte[3 - i] = (paramInt >> (i * 8));
     return arrayOfByte;
}

I mostly agree with the accepted answer, but there is a C++11 option that has not been covered in existing answers:

• Return factory method results by value, and
• Provide a cheap move constructor.

Example:

struct sandwich {
  // Factory methods.
  static sandwich ham();
  static sandwich spam();
  // Move constructor.
  sandwich(sandwich &&);
  // etc.
};

Then you can construct objects on the stack:

sandwich mine{sandwich::ham()};

As subobjects of other things:

auto lunch = std::make_pair(sandwich::spam(), apple{});

Or dynamically allocated:

auto ptr = std::make_shared<sandwich>(sandwich::ham());

When might I use this?

If, on a public constructor, it is not possible to give meaningful initialisers for all class members without some preliminary calculation, then I might convert that constructor to a static method. The static method performs the preliminary calculations, then returns a value result via a private constructor which just does a member-wise initialisation.

I say 'might' because it depends on which approach gives the clearest code without being unnecessarily inefficient.

Here I think it's worth mentioning SORT BY and ORDER BY both clauses and why they different,

SELECT * FROM <table_name> SORT BY <column_name> DESC LIMIT 2

If you are using SORT BY clause it sort data per reducer which means if you have more than one MapReduce task it will result partially ordered data. On the other hand, the ORDER BY clause will result in ordered data for the final Reduce task. To understand more please refer to this link.

SELECT * FROM <table_name> ORDER BY <column_name> DESC LIMIT 2

Note: Finally, Even though the accepted answer contains SORT BY clause, I mostly prefer to use ORDER BY clause for the general use case to avoid any data loss.

If you have no opportunity to change name="submit" you can also submit form this way:

function submitForm(form) {
    const submitFormFunction = Object.getPrototypeOf(form).submit;
    submitFormFunction.call(form);
}

To pass/use the variables, first create parameters in the configure section of Jenkins. Parameters that you use can be of type text, String, file, etc.

After creating them, use the variable reference in the fields you want to.

For example: I have configured/created two variables for Email-subject and Email-recipentList, and I have used their reference in the EMail-ext plugin (attached screenshot).

Justin has given you some very fine tips :)

You will also get that error if the cell where you are performing the calculation has an error resulting from a formula.

For example if Cell A1 has #DIV/0! error then you will get "Excel VBA Run-time error '13' Type mismatch" when performing this code

Sheets("Sheet1").Range("A1").Value - 1

I have made some slight changes to your code. Could you please test it for me? Copy the code with the line numbers as I have deliberately put them there.

ROOT default app is usually Tomcat Manager - which can be useful so I felt like keeping it around.

So the way i made my app ROOT and kept TCmgr was like this.

renamed ROOT to something else

mv ROOT TCmgr

then created a symbolic link whereby ROOT points to the app i want to make the default.

ln -s <your app> ROOT

worked for me and seemed the easiest approach.

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

There are some properties/methods you can use:

$().scrollTop()//how much has been scrolled
$().innerHeight()// inner height of the element
DOMElement.scrollHeight//height of the content of the element

So you can take the sum of the first two properties, and when it equals to the last property, you've reached the end:

jQuery(function($) {
    $('#flux').on('scroll', function() {
        if($(this).scrollTop() + $(this).innerHeight() >= $(this)[0].scrollHeight) {
            alert('end reached');
        }
    })
});

http://jsfiddle.net/doktormolle/w7X9N/

Edit: I've updated 'bind' to 'on' as per:

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document.

You can do it using Primefaces like this :

<p:button 
      outcome="/page2.xhtml?faces-redirect=true&amp;id=#{myBean.id}">
</p:button>

yet another way (my favorite), starting with C# 6

private readonly int MyVal = 5;

public int MyProp => MyVal;

With HTML5's support for svg, you don't need to rely on shadow hacks.

<svg  width="100%" viewBox="0 0 600 100">_x000D_
<text x=0 y=20 font-size=12pt fill=white stroke=black stroke-width=0.75>_x000D_
    This text exposes its vector representation, _x000D_
    making it easy to style shape-wise without hacks. _x000D_
    HTML5 supports it, so no browser issues. Only downside _x000D_
    is that svg has its own quirks and learning curve _x000D_
    (c.f. bounding box issue/no typesetting by default)_x000D_
</text>_x000D_
</svg>

Edit your C:\Windows\System32\drivers\etc\hosts file

Make sure there is an entry that looks like this:

127.0.0.1   localhost

If there is an entry like

::  localhost

Comment it out to look like this

\#:: localhost

This should fix your problem, I've had this problem in the past.

SELECT U.*, V.* FROM users AS U 
INNER JOIN (SELECT *
FROM payments
WHERE id IN (
SELECT MAX(id)

GROUP BY user_id
)) AS V ON U.id = V.user_id

This will get it working

clear your cache and cookies in Safari, make sure your device is in provisioning profile and provisioning profile is installed on the device.

If everything mentioned above didn't help, try to create a new build with higher build number and try to distribute your app again

With the plugin: jQuery Selection Box. You can do this:

var myOptions = {
        "Value 1" : "Text 1",
        "Value 2" : "Text 2",
        "Value 3" : "Text 3"
    }
    $("#myselect2").addOption(myOptions, false);

This approach with ViewGroup.MarginLayoutParams worked for me:

RelativeLayout myLayout = (RelativeLayout) findViewById(R.id.my_layout);

TextView someTextView = ...

int leftMargin = Util.getXPos();
int topMargin = Util.getYPos();

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
    new ViewGroup.MarginLayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT));

lp.setMargins(leftMargin, topMargin, 0, 0);

myLayout.addView(someTextView, lp);

If you're looking to quickly implement this in a Rails controller action to send a JSON response:

def index
  my_json = '{ "key": "value" }'
  render json: JSON.pretty_generate( JSON.parse my_json )
end

It's not a direct answer to the question, however I would suggest in most cases to simply set multiple classes to each element:

<div class="myclass one"></div>
<div class="myclass two></div>
<div class="myclass three"></div>

In this way you can set rules for all myclass elements and then more specific rules for one, two and three.

.myclass { color: #f00; }

.two { font-weight: bold; }

etc.

A version that avoids creating a sub-process:

for D in *; do
    if [ -d "${D}" ]; then
        echo "${D}"   # your processing here
    fi
done

Or, if your action is a single command, this is more concise:

for D in *; do [ -d "${D}" ] && my_command; done

Or an even more concise version (thanks @enzotib). Note that in this version each value of D will have a trailing slash:

for D in */; do my_command; done

In addition to the refactoring and source control tools listed here, AQTime is a great windows profiler. It can run as a plugin or stand-alone and it works with .NET and native code.

Using & operator, don't forget to wrap the sub-statements with ():

males = df[(df[Gender]=='Male') & (df[Year]==2014)]

To store your dataframes in a dict using a for loop:

from collections import defaultdict
dic={}
for g in ['male', 'female']:
  dic[g]=defaultdict(dict)
  for y in [2013, 2014]:
    dic[g][y]=df[(df[Gender]==g) & (df[Year]==y)] #store the DataFrames to a dict of dict

EDIT:

A demo for your getDF:

def getDF(dic, gender, year):
  return dic[gender][year]

print genDF(dic, 'male', 2014)

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

You can use Paros to sniff the network traffic from your iPhone. See this excellent step by step post for more information: http://blog.jerodsanto.net/2009/06/sniff-your-iphones-network-traffic/. Also, look in the comments for some advice for using other proxies to get the same job done.

One caveat is that Paras only sniffs HTTP GET/POST requests using the method above, so to sniff all network traffic, try the following:

1. Just turn on network sharing over WiFi and run a packet sniffer like Cocoa Packet Analyzer (in OSX).
2. Then connect to the new network from iPhone over WiFi. (SystemPreferences->Sharing->InternetSharing)

If you're after sniffing these packets on Windows, connect to the internet using Ethernet, share your internet connection, and use the Windows computer as your access point. Then, just run Wireshark as normal and intercept the packets flowing through, filtering by their startpoints. Alternatively, try using a network hub as Wireshark can trace all packets flowing through a network if they are using the same router endpoint address (as in a hub).

For user crontabs (including root), you can do something like:

crontab -l -u user | cat - filename | crontab -u user -

where the file named "filename" contains items to append. You could also do text manipulation using sed or another tool in place of cat. You should use the crontab command instead of directly modifying the file.

A similar operation would be:

{ crontab -l -u user; echo 'crontab spec'; } | crontab -u user -

If you are modifying or creating system crontabs, those may be manipulated as you would ordinary text files. They are stored in the /etc/cron.d, /etc/cron.hourly, /etc/cron.daily, /etc/cron.weekly, /etc/cron.monthly directories and in the files /etc/crontab and /etc/anacrontab.

Try to using application/* instead. And use JSON.maybeJson() to check the data structure in the controller.

Why don't you just use the database diagram functionality built into SQL Server?

Why all this code in the samples above...

A struct with explicit layout acts both ways and has no performance hit.

Update: Since there's a question on how to deal with endianness I added an interface that illustrates how to abstract that. Another implementing struct can deal with the opposite case

public interface IIntToByte
{
    Int32 Int { get; set;}

    byte B0 { get; }
    byte B1 { get; }
    byte B2 { get; }
    byte B3 { get; }
}

[StructLayout(LayoutKind.Explicit)]
public struct IntToByteLE : UserQuery.IIntToByte
{
    [FieldOffset(0)]
    public Int32 IntVal;

    [FieldOffset(0)]
    public byte b0;
    [FieldOffset(1)]
    public byte b1;
    [FieldOffset(2)]
    public byte b2;
    [FieldOffset(3)]
    public byte b3;

    public Int32 Int {
        get{ return IntVal; }
        set{ IntVal = value;}
    }

    public byte B0 => b0;
    public byte B1 => b1;
    public byte B2 => b2;
    public byte B3 => b3; 
}

From PHP 7.1 you can do this (Accepted rfc for negative string offsets):

<?php
$silly = 'Mary had a little lamb';
echo $silly[-20];
echo $silly{-6};
echo $silly[-3];
echo $silly[-15];
echo $silly[-13];
echo $silly[-1];
echo $silly[-4];
echo $silly{-10};
echo $silly[-4];
echo $silly[-8];
echo $silly{3}; // <-- this will be deprecated in PHP 7.4
die();

I'll let you guess the output.

Also, I added this to xenonite's performance code with these results:

substr() took 7.0334868431091seconds

array access took 2.3111131191254seconds

Direct string access (negative string offsets) took 1.7971360683441seconds

you could see this info

for i in /var/run/*;do echo -n "$i "; find $i| wc -l;done | column -t

input:focus {
    outline:none;
}

This will do. Orange outline won't show up anymore.

When using angular.copy, instead of updating the reference, a new object is created and assigned to the destination(if a destination is provided). But there's more. There's this cool thing that happens after a deep copy.

Say you have a factory service which has methods which updates factory variables.

angular.module('test').factory('TestService', [function () {
    var o = {
        shallow: [0,1], // initial value(for demonstration)
        deep: [0,2] // initial value(for demonstration)
    }; 
    o.shallowCopy = function () {
        o.shallow = [1,2,3]
    }
    o.deepCopy = function () {
        angular.copy([4,5,6], o.deep);
    }
    return o;
}]);

and a controller which uses this service,

angular.module('test').controller('Ctrl', ['TestService', function (TestService) {
     var shallow = TestService.shallow;
     var deep = TestService.deep;

     console.log('****Printing initial values');
     console.log(shallow);
     console.log(deep);

     TestService.shallowCopy();
     TestService.deepCopy();

     console.log('****Printing values after service method execution');
     console.log(shallow);
     console.log(deep);

     console.log('****Printing service variables directly');
     console.log(TestService.shallow);
     console.log(TestService.deep);
}]);

When the above program is run the output will be as follows,

****Printing initial values
[0,1]
[0,2]

****Printing values after service method execution
[0,1]
[4,5,6]

****Printing service variables directly
[1,2,3]
[4,5,6]

Thus the cool thing about using angular copy is that, the references of the destination are reflected with the change of values, without having to re-assign the values manually, again.

For those of us on corporate networks using web filters that implement trusted man in the middle SSL solutions, it is necessary to add the web-filter certificate to the certifi cacert.pem.

A guide to doing this is here.

Main steps are:

1. connect to https site with browser
2. view and save root certificate
3. convert cert to .pem
4. copy and paste onto end of existing cacert.pem
5. save
6. SSL happiness

I did some tests in Firefox 3 comparing the value of .src and .documentWindow.location.href in an iframe. (Note: The documentWindow is called contentDocument in Chrome, so instead of .documentWindow.location.href in Chrome it will be .contentDocument.location.href.)

src is always the last URL that was loaded in the iframe without user interaction. I.e., it contains the first value for the URL, or the last value you set up with Javascript from the containing window doing:

document.getElementById("myiframe").src = 'http://www.google.com/';

If the user navigates inside the iframe, you can't anymore access the value of the URL using src. In the previous example, if the user goes away from www.google.com and you do:

alert(document.getElementById("myiframe").src);

You will still get "http://www.google.com".

documentWindow.location.href is only available if the iframe contains a page in the same domain as the containing window, but if it's available it always contains the right value for the URL, even if the user navigates in the iframe.

If you try to access documentWindow.location.href (or anything under documentWindow) and the iframe is in a page that doesn't belong to the domain of the containing window, it will raise an exception:

document.getElementById("myiframe").src = 'http://www.google.com/';
alert(document.getElementById("myiframe").documentWindow.location.href);
Error: Permission denied to get property Location.href

I have not tested any other browser.

Hope it helps!

Only one condition, I tested that it wasn't null was, if you allow enough time to user to touch the "get my location" layer button, then it will not get null value.

"When Html.RenderPartial() is called with just the name of the partial view, ASP.NET MVC will pass to the partial view the same Model and ViewData dictionary objects used by the calling view template."

I had used JCL about 2 years back so cannot write a code for you but here is the idea;

1. Have 2 steps
2. First step will have ICETOOl where you can write the matching records to matched file.
3. Second you can write a file for mismatched by using SORT/ICETOOl or by just file operations.

again i apologize for solution without code, but i am out of touch by 2 yrs+

How about iPhone Configuration Utility?

http://support.apple.com/kb/DL1465?viewlocale=en_US&locale=en_US

iPhone Configuration Utility lets you easily create, maintain, encrypt, and install configuration profiles, track and install provisioning profiles and authorized applications, and capture device information including console logs.

Update:

Apple Configurator replaces iPhone Configuration Utility. With the the release of iOS 8, iPhone Configuration Utility is no longer supported or available for download. https://itunes.apple.com/gb/app/apple-configurator/id434433123

Java has a large number of built-in exceptions for different scenarios.

In this case, you should throw an IllegalArgumentException, since the problem is that the caller passed a bad parameter.

As all have mentioned it is

request.getHeader("referer");

I would like to add some more details about security aspect of referer header in contrast with accepted answer. In Open Web Application Security Project(OWASP) cheat sheets, under Cross-Site Request Forgery (CSRF) Prevention Cheat Sheet it mentions about importance of referer header.

More importantly for this recommended Same Origin check, a number of HTTP request headers can't be set by JavaScript because they are on the 'forbidden' headers list. Only the browsers themselves can set values for these headers, making them more trustworthy because not even an XSS vulnerability can be used to modify them.

The Source Origin check recommended here relies on three of these protected headers: Origin, Referer, and Host, making it a pretty strong CSRF defense all on its own.

You can refer Forbidden header list here. User agent(ie:browser) has the full control over these headers not the user.

public class Jclass {

    public String uname ;
    /**

     */
    public String getUname() {
        return uname;

    }

    public Jclass() {
        this.uname = null;
    }

    public static void main(String[] args) {

    }
}

JSP file: sample.jsp

    <%@ page language="java"
    import="java.util.*,java.io.*"
    pageEncoding="ISO-8859-1"%>

<jsp:directive.page import="Jclasspackage.Jclass.java" />   
<% Jclass jc = new Jclass();
String username = (String)request.getAttribute("un")
jc.setUname(username);
%>

-----------------

In this way you can access the username in the java file using "this.username" in the class

The cleanest way to work with it. Assuming your table is a list of integers called "dbo.tvp_Int" (Customize for your own table type)

Create this extension method...

public static void AddWithValue_Tvp_Int(this SqlParameterCollection paramCollection, string parameterName, List<int> data)
{
   if(paramCollection != null)
   {
       var p = paramCollection.Add(parameterName, SqlDbType.Structured);
       p.TypeName = "dbo.tvp_Int";
       DataTable _dt = new DataTable() {Columns = {"Value"}};
       data.ForEach(value => _dt.Rows.Add(value));
       p.Value = _dt;
   }
}

Now you can add a table valued parameter in one line anywhere simply by doing this:

cmd.Parameters.AddWithValueFor_Tvp_Int("@IDValues", listOfIds);

Here 2 pure bash solutions using only ffmpeg and not using

• an intermediary file
• perl, python nor javascript

One-liner solution using ls

ls video1.mp4 video2.mp4 | while read line; do echo file \'$line\'; done | ffmpeg -protocol_whitelist file,pipe -f concat -i - -c copy output.mp4

Function which takes 0 or 2+ arguments

#######################################
# Merge mp4 files into one output mp4 file
# usage:
#   mergemp4 #merges all mp4 in current directory
#   mergemp4 video1.mp4 video2.mp4
#   mergemp4 video1.mp4 video2.mp4 [ video3.mp4 ...] output.mp4 
#######################################
function mergemp4() {
  if [ $# = 1 ]; then return; fi

  outputfile="output.mp4"

  #if no arguments we take all mp4 in current directory as array
  if [ $# = 0 ]; then inputfiles=($(ls -1v *.mp4)); fi
  if [ $# = 2 ]; then inputfiles=($1 $2); fi  
  if [ $# -ge 3 ]; then
    outputfile=${@: -1} # Get the last argument
    inputfiles=(${@:1:$# - 1}) # Get all arguments besides last one as array
  fi
  
  # -y: automatically overwrite output file if exists
  # -loglevel quiet: disable ffmpeg logs
  ffmpeg -y \
  -loglevel quiet \
  -f concat \
  -safe 0 \
  -i <(for f in $inputfiles; do echo "file '$PWD/$f'"; done) \
  -c copy $outputfile

  if test -f "$outputfile"; then echo "$outputfile created"; fi
}

Note: had tried some solutions in this thread and none satisfied me

The answer of Mark Byers is the optimal in this situation. Though in more complex situations you can take the select query that returns rowids and calculated values and attach it to the update query like this:

with t as (
  -- Any generic query which returns rowid and corresponding calculated values
  select t1.id as rowid, f(t2, t2) as calculatedvalue
  from table1 as t1
  join table2 as t2 on t2.referenceid = t1.id
)
update table1
set value = t.calculatedvalue
from t
where id = t.rowid

This approach lets you develop and test your select query and in two steps convert it to the update query.

So in your case the result query will be:

with t as (
    select v.id as rowid, s.price_per_vehicle as calculatedvalue
    from vehicles_vehicle v 
    join shipments_shipment s on v.shipment_id = s.id 
)
update vehicles_vehicle
set price = t.calculatedvalue
from t
where id = t.rowid

Note that column aliases are mandatory otherwise PostgreSQL will complain about the ambiguity of the column names.

That is because you are using PHP 5.5 or your webserver would have been upgraded to 5.5.0.

The mysql_* functions has been deprecated as of 5.5.0

If you want a function which will return an arbitrary number of zeros in a list, try this:

def make_zeros(number):
    return [0] * number

list = make_zeros(10)

# list now contains: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

Export a certificate from a keystore:

First of all, when you put that code in applicationDidFinishLaunching, it might be the case that controllers instantiated from Interface Builder are not yet linked to your application (so "red" and "blue" are still nil).

But to answer your initial question, what you're doing wrong is that you're calling dismissModalViewControllerAnimated: on the wrong controller! It should be like this:

[blue presentModalViewController:red animated:YES];
[red dismissModalViewControllerAnimated:YES];

Usually the "red" controller should decide to dismiss himself at some point (maybe when a "cancel" button is clicked). Then the "red" controller could call the method on self:

[self dismissModalViewControllerAnimated:YES];

If it still doesn't work, it might have something to do with the fact that the controller is presented in an animation fashion, so you might not be allowed to dismiss the controller so soon after presenting it.

The default locations of Chrome's profile directory are defined at http://www.chromium.org/user-experience/user-data-directory. For Chrome on Mac, it's

~/Library/Application\ Support/Google/Chrome/Default

The actual location can be different, by setting the --user-data-dir=path/to/directory flag.
If only one user is registered in Chrome, look in the Default/Extensions subdirectory. Otherwise, look in the <profile user name>/Extensions directory.

If that didn't help, you can always do a custom search.

1. Go to chrome://extensions/, and find out the ID of an extension (32 lowercase letters) (if not done already, activate "Developer mode" first).

   

2. Open the terminal, cd to the directory which is most likely a parent of your Chrome profile (if unsure, try ~ then /).

3. Run find . -type d -iname "<EXTENSION ID HERE>", for example:

   find . -type d -iname jifpbeccnghkjeaalbbjmodiffmgedin
   

   Result:

   

You can use a FilenameFilter, like so:

File dir = new File(directory);

File[] matches = dir.listFiles(new FilenameFilter()
{
  public boolean accept(File dir, String name)
  {
     return name.startsWith("temp") && name.endsWith(".txt");
  }
});

I had this problem inconsistently between different platforms, as I got JSON as String from Mapper and did the writing myself. Sometimes it went into file as ansi and other times correctly as UTF8. I switched to

mapper.writeValue(file, data);

letting Mapper do the file operations, and it started working fine.

Complete the following steps in Eclipse to get plugins for JavaScript files:

1. Open Eclipse -> Go to "Help" -> "Install New Software"
2. Select the repository for your version of Eclipse. I have Juno so I selected http://download.eclipse.org/releases/juno
3. Expand "Programming Languages" -> Check the box next to "JavaScript Development Tools"
4. Click "Next" -> "Next" -> Accept the Terms of the License Agreement -> "Finish"
5. Wait for the software to install, then restart Eclipse (by clicking "Yes" button at pop up window)
6. Once Eclipse has restarted, open "Window" -> "Preferences" -> Expand "General" and "Editors" -> Click "File Associations" -> Add ".js" to the "File types:" list, if it is not already there
7. In the same "File Associations" dialog, click "Add" in the "Associated editors:" section
8. Select "Internal editors" radio at the top
9. Select "JavaScript Viewer". Click "OK" -> "OK"

To add JavaScript Perspective: (Optional)
10. Go to "Window" -> "Open Perspective" -> "Other..."
11. Select "JavaScript". Click "OK"

To open .html or .js file with highlighted JavaScript syntax:
12. (Optional) Select JavaScript Perspective
13. Browse and Select .html or .js file in Script Explorer in [JavaScript Perspective] (Or Package Explorer [Java Perspective] Or PyDev Package Explorer [PyDev Perspective] Don't matter.)
14. Right-click on .html or .js file -> "Open With" -> "Other..."
15. Select "Internal editors"
16. Select "Java Script Editor". Click "OK" (see JavaScript syntax is now highlighted )

I have written some code to implement the trim functionality.

LTRIM (trim left):

function ltrim(s)
{
    var l=0;
    while(l < s.length && s[l] == ' ')
    {   l++; }
    return s.substring(l, s.length);
} 

RTRIM (trim right):

function rtrim(s)
{
    var r=s.length -1;
    while(r > 0 && s[r] == ' ')
    {   r-=1;   }
    return s.substring(0, r+1);
 }

TRIM (trim both sides):

function trim(s)
{
    return rtrim(ltrim(s));
}

OR

Regular expression is also available which we can use.

function trimStr(str) {
  return str.replace(/^\s+|\s+$/g, '');
}

Useful Explanation

I know this has been said earlier, but jQuery Autocomplete will do exactly what you need. You should check out the docs as the autocomplete is very customizable. If you are familiar with javascript then you should be able to work this out. If not I can give you a few pointers, as I have done this once before, but beware I am not well versed in javascript myself either, so bear with me on this.

I think the first thing you should do is just get a simple autocomplete text field working on your page, and then you can customize it from there.

The autocomplete widget accepts JSON data as it's 'source:' option. So you should set-up your app to produce the 20 top level categories, and subcategories in JSON format.

The next thing to know is that when the user types into your textfield, the autocomplete widget will send the typed values in a parameter called "term".

So let's say you first set-up your site to deliver the JSON data from a URL like this:

/categories.json

Then your autocomplete source: option would be 'source: /categories.json'.

When a user types into the textfield, such as 'first-cata...' the autocomplete widget will start sending the value in the 'term' parameter like this:

/categories.json?term=first-cata

This will return JSON data back to the widget filtered by anything that matches 'first-cata', and this is displayed as an autocomplete suggestion.

I am not sure what you are programming in, but you can specify how the 'term' parameter finds a match. So you can customize this, so that the term finds a match in the middle of a word if you want. Example, if the user types 'or' you code could make a match on 'sports'.

Lastly, you made a comment that you want to be able to select a category name but have the autocomplete widget submit the category ID not the name.

This can easily be done with a hidden field. This is what is shown in the jQuery autocomplete docs.

When a user selects a category, your JavaScript should update a hidden field with the ID.

I know this answer is not very detailed, but that is mainly because I am not sure what you are programming in, but the above should point you in the right direction. The thing to know is that you can do practically any customizing you want with this widget, if you are willing to spend the time to learn it.

These are the broad strokes, but you can look here for some notes I made when I implemented something similar to what you want in a Rails app.

Hope this helped.

Solve this using java ( UTF-16LE with BOM ):

String csvReportStr = getCsvReport();
byte[] data = Charset.forName("UTF-16LE").encode(csvReportStr)
    .put(0, (byte) 0xFF)
    .put(1, (byte) 0xFE)
    .array();

Note that CSV file should use TAB as separator. You can read the CSV file both on windows and MAC OS X.

Refer to: How do I encode/decode UTF-16LE byte arrays with a BOM?

public class MyMap {

public static void main(String[] args) {

    Map<String, String> map1 = new HashMap<String, String>();
    map1.put("key1", "value1");
    map1.put("key2", "value2");
    map1.put("key3", "value3");
    map1.put(null, null);

    Map<String, String> map2 = new HashMap<String, String>();
    map2.put("key4", "value4");
    map2.put("key5", "value5");
    map2.put("key6", "value6");
    map2.put("key3", "replaced-value-of-key3-in-map2");
    // used only if map1 can be changes/updates with the same keys present in map2.
    map1.putAll(map2);

    // use below if you are not supposed to modify the map1.
    for (Map.Entry e : map2.entrySet())
        if (!map1.containsKey(e.getKey()))
            map1.put(e.getKey().toString(), e.getValue().toString());
    System.out.println(map1);
}}

It was giving Illegal Exception.

My workaround with code:

public void dofirst(){
    System.setProperty("webdriver.chrome.driver","D:\\Softwares\\selenium\\chromedriver_win32\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    driver.get("http://www.facebook.com");
}

>>> locals()['foo']
{}
>>> globals()['foo']
{}

If you wanted to write your own function, it could be done such that you could check for a variable defined in locals then check globals. If nothing is found you could compare on id() to see if the variable points to the same location in memory.

If your variable is in a class, you could use className.dict.keys() or vars(self) to see if your variable has been defined.

Easiest Way: Connect to Sqlite3 via ADB Shell

I haven't found any way to do that in Android Studio, but I access the db with a remote shell instead of pulling the file each time.

Find all info here: http://developer.android.com/tools/help/sqlite3.html

1- Go to your platform-tools folder in a command prompt

2- Enter the command adb devices to get the list of your devices

C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb devices
List of devices attached
emulator-xxxx   device

3- Connect a shell to your device:

C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb -s emulator-xxxx shell

4a- You can bypass this step on rooted device

run-as <your-package-name> 

4b- Navigate to the folder containing your db file:

cd data/data/<your-package-name>/databases/

5- run sqlite3 to connect to your db:

sqlite3 <your-db-name>.db

6- run sqlite3 commands that you like eg:

Select * from table1 where ...;

Note: Find more commands to run below.

SQLite cheatsheet

There are a few steps to see the tables in an SQLite database:

1. List the tables in your database:

   .tables
   

2. List how the table looks:

   .schema tablename
   

3. Print the entire table:

   SELECT * FROM tablename;
   

4. List all of the available SQLite prompt commands:

   .help

The fact that the same number of rows is returned is an after fact, the query optimizer cannot know in advance that every row in Accepts has a matching row in Marker, can it?

If you join two tables A and B, say A has 1 million rows and B has 1 row. If you say A LEFT INNER JOIN B it means only rows that match both A and B can result, so the query plan is free to scan B first, then use an index to do a range scan in A, and perhaps return 10 rows. But if you say A LEFT OUTER JOIN B then at least all rows in A have to be returned, so the plan must scan everything in A no matter what it finds in B. By using an OUTER join you are eliminating one possible optimization.

If you do know that every row in Accepts will have a match in Marker, then why not declare a foreign key to enforce this? The optimizer will see the constraint, and if is trusted, will take it into account in the plan.

There are several reasons you could have problems loading from lib - see here for details - http://www.williambharding.com/blog/technology/rails-3-autoload-modules-and-classes-in-production/

• fix autoload path
• threadsafe related
• naming relating
• ...

A very simple solution:

df <- read.csv("df.csv",sep=",",head=T)
x <- cbind(df$Xax,df$Xax,df$Xax,df$Xax)
y <- cbind(df$A,df$B,df$C,df$D)
matplot(x,y,type="p")

please note it just plots the data and it does not plot any regression line.

You probably don't want to do this:

#include "client.cpp"

A *.cpp file will have been compiled by the compiler as part of your build. By including it in other files, it will be compiled again (and again!) in every file in which you include it.

Now here's the thing: You are guarding it with #ifndef SOCKET_CLIENT_CLASS, however, each file that has #include "client.cpp" is built independently and as such will find SOCKET_CLIENT_CLASS not yet defined. Therefore it's contents will be included, not #ifdef'd out.

If it contains any definitions at all (rather than just declarations) then these definitions will be repeated in every file where it's included.

The first thing I will try - determine if your code with alerts is actually rendered. I see some server "if" code in what you posted, so may be condition to render javascript is not satisfied. So, on the page you working on, right-click -> view source. Try to find the js code there. Please tell us if you found the code on the page.

Just like @porneL said, the C api is very handy.

NSString* fileRoot = [[NSBundle mainBundle] pathForResource:@"record" ofType:@"txt"];
FILE *file = fopen([fileRoot UTF8String], "r");
char buffer[256];
while (fgets(buffer, 256, file) != NULL){
    NSString* result = [NSString stringWithUTF8String:buffer];
    NSLog(@"%@",result);
}

you can try this (I don't have sql server here today so I can't verify syntax, sorry)

select attributeName
  from tableName
 where CONVERT(varchar,attributeName,101) BETWEEN '03/01/2009' AND '03/31/2009'
   and CONVERT(varchar, attributeName,108) BETWEEN '06:00:00' AND '22:00:00'
   and DATEPART(day,attributeName) BETWEEN 2 AND 4

To fetch single row

$result = $this->getEntityManager()->getConnection()->fetchAssoc($sql)

To fetch all records

$result = $this->getEntityManager()->getConnection()->fetchAll($sql)

Here you can use sql native query, all will work without any issue.

set up a new postgresql server and replace its data folder with the files from your external disk.

You will then be able to start that postgresql server up and retrieve the data using pg_dump (pg_dump -s for the schema-only as mentioned)

Thanks to dee for the answer above with the Scrape() subroutine. The code worked perfectly as written, and I was able to then convert the code to work with the specific website I am trying to scrape.

I do not have enough reputation to upvote or to comment, but I do actually have some minor improvements to add to dee's answer:

1. You will need to add the VBA Reference via "Tools\References" to "Microsoft HTML Object Library in order for the code to compile.

2. I commented out the Browser.Visible line and added the comment as follows

   'if you need to debug the browser page, uncomment this line:
   'Browser.Visible = True
   

3. And I added a line to close the browser before Set Browser = Nothing:

   Browser.Quit
   

Thanks again dee!

ETA: this works on machines with IE9, but not machines with IE8. Anyone have a fix?

Found the fix myself, so came back here to post it. The ClassName function is available in IE9. For this to work in IE8, you use querySelectorAll, with a dot preceding the class name of the object you are looking for:

'Set repList = doc.getElementsByClassName("reportList") 'only works in IE9, not in IE8
Set repList = doc.querySelectorAll(".reportList")       'this works in IE8+

Tony is a pure genius. However to achieve even better auto-completion try setting the triggers to this:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz =.(!+-*/~,[{@#$%^&

(specifically aranged in order of usage for faster performance :)

Flex layout modes are not (fully) natively supported in IE yet. IE10 implements the "tween" version of the spec which is not fully recent, but still works.

https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes

This CSS-Tricks article has some advice on cross-browser use of flexbox (including IE): http://css-tricks.com/using-flexbox/

edit: after a bit more research, IE10 flexbox layout mode implemented current to the March 2012 W3C draft spec: http://www.w3.org/TR/2012/WD-css3-flexbox-20120322/

The most current draft is a year or so more recent: http://dev.w3.org/csswg/css-flexbox/

.a files are static libraries typically generated by the archive tool. You usually include the header files associated with that static library and then link to the library when you are compiling.

Use jline3:

Example:

Terminal terminal = TerminalBuilder.builder()
    .jna(true)
    .system(true)
    .build();

// raw mode means we get keypresses rather than line buffered input
terminal.enterRawMode();
reader = terminal .reader();
...
int read = reader.read();
....
reader.close();
terminal.close();

use

SELECT DISTINCT Date FROM buy ORDER BY Date

so MySQL removes duplicates

BTW: using explicit column names in SELECT uses less resources in PHP when you're getting a large result from MySQL

def is_ascii(s):
    return all(ord(c) < 128 for c in s)

Error can be caused by various issues. for more info check suexec or fcgi logs. For example if suexec has wrong user and permssion it can cause the error to occur to solve try

chgrp WEBGROUP /usr/local/apache2/bin/suexec
chmod 4750 /usr/local/apache2/bin/suexec

Manually add it when you build the query:

SELECT 'Site1' AS SiteName, t1.column, t1.column2
FROM t1

UNION ALL
SELECT 'Site2' AS SiteName, t2.column, t2.column2
FROM t2

UNION ALL
...

EXAMPLE:

DECLARE @t1 TABLE (column1 int, column2 nvarchar(1))
DECLARE @t2 TABLE (column1 int, column2 nvarchar(1))

INSERT INTO @t1
SELECT 1, 'a'
UNION SELECT 2, 'b'

INSERT INTO @t2
SELECT 3, 'c'
UNION SELECT 4, 'd'


SELECT 'Site1' AS SiteName, t1.column1, t1.column2
FROM @t1 t1

UNION ALL
SELECT 'Site2' AS SiteName, t2.column1, t2.column2
FROM @t2 t2

RESULT:

SiteName  column1  column2
Site1       1      a
Site1       2      b
Site2       3      c
Site2       4      d

I'd recommend using Promise.all as mentioned above, but if you really feel like avoiding that approach, you can do a for or any other loop:

const arr = [1,2,3,4,5];
let resultingArr = [];
for (let i in arr){
  await callAsynchronousOperation(i);
  resultingArr.push(i + 1)
}

If you are lucky enough to develop on Kotlin, just create an extension function:

fun String.toSpanned(): Spanned {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return Html.fromHtml(this, Html.FROM_HTML_MODE_LEGACY)
    } else {
        @Suppress("DEPRECATION")
        return Html.fromHtml(this)
    }
}

And then it's so sweet to use it everywhere:

yourTextView.text = anyString.toSpanned()

Simple use this to strip the text :

echo strlen($string) >= 500 ? 
substr($string, 0, 490) . ' <a href="link/to/the/entire/text.htm">[Read more]</a>' : 
$string;

Edit and finally :

function split_words($string, $nb_caracs, $separator){
    $string = strip_tags(html_entity_decode($string));
    if( strlen($string) <= $nb_caracs ){
        $final_string = $string;
    } else {
        $final_string = "";
        $words = explode(" ", $string);
        foreach( $words as $value ){
            if( strlen($final_string . " " . $value) < $nb_caracs ){
                if( !empty($final_string) ) $final_string .= " ";
                $final_string .= $value;
            } else {
                break;
            }
        }
        $final_string .= $separator;
    }
    return $final_string;
}

Here separator is the href link to read more ;)

To concatenate strings, use the + operator.

To insert data into a URI, encode it for URIs.

Bad:

var url = "http://localhost:8080/login?cid='username'&pwd='password'"

Good:

var url_safe_username = encodeURIComponent(username);
var url_safe_password = encodeURIComponent(password);
var url = "http://localhost:8080/login?cid=" + url_safe_username + "&pwd=" + url_safe_password;

The server will have to process the query string to make use of the data. You can't assign to arbitrary form fields.

… but don't trigger new windows or pass credentials in the URI (where they are exposed to over the shoulder attacks and may be logged).

This works:

assertThat(list,IsEmptyCollection.empty())

Another solution is to use a shortcut file to cmd.exe instead of a batch file.

Edit the shortcut's start in property to %~dp0.

You achieve the same thing, except it has the Cmd icon (and you can change this).

Some people don't like clicking on batch files without knowing what's in them, and some corporate network drives have a ban on .bat files...

I am going to use an example to add to the answers above.

I ran into proxy issues while trying to install packages via Web Platform Installer

That too uses a config file which is WebPlatformInstaller.exe.config

I tried the edits suggest in this IIS forum which is

<?xml version="1.0" encoding="utf-8" ?>
<configuration>  
  <system.net>    
     <defaultProxy enabled="True" useDefaultCredentials="True"/>      
   </system.net>
</configuration>

and

<?xml version="1.0" encoding="utf-8" ?>
<configuration>  
   <system.net>    
     <defaultProxy>      
          <proxy 
               proxyaddress="http://yourproxy.company.com:80" 
               usesystemdefault="True"
               autoDetect="False" />    
     </defaultProxy>  
   </system.net>
</configuration>

None of these worked.

What worked for me was this -

<system.net>    
    <defaultProxy enabled="true" useDefaultCredentials="false">
      <module type="WebPI.Net.AuthenticatedProxy, WebPI.Net, Version=1.0.0.0, Culture=neutral, PublicKeyToken=79a8d77199cbf3bc" />
    </defaultProxy>  
 </system.net>

The module needed to be registered with Web Platform Installer in order to use it.

Standard is use is or has as a prefix. For example isValid, hasChildren.

But again main doubt why TextView resource id it needs?

Look at the constructor and the params.

public ArrayAdapter (Context context, int resource, int textViewResourceId, T[] objects)

Added in API level 1 Constructor

Parameters

context The current context.

resource The resource ID for a layout file containing a layout to use when instantiating views.

textViewResourceId The id of the TextView within the layout resource to be populated objects The objects to represent in the ListView.

android.R.id.text1 refers to the id of text in android resource. So you need not have the one in your activity.

Here's the full list

http://developer.android.com/reference/android/R.id.html

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1, android.R.id.text1, values);

this refers to activity context

android.R.layout.simple_list_item_1 simple_list_item_1 is the layout in android.R.layout.

android.R.id.text1 refers to the android resource id.

values is a string array from the link you provided

http://developer.android.com/reference/android/R.layout.html

Exceding the maximum value of a long doesnt throw an exception, instead it cicles back. If you do this:

Long.MAX_VALUE + 1

you will notice that the result is the equivalent to Long.MIN_VALUE.

From here: java number exceeds long.max_value - how to detect?

Lots of good answers here, just out of curiosity after looking into this today, is it not best to use setInterval rather than the setTimeout?

setInterval(function() {
location.reload();
}, 30000);

let me know you thoughts.

Use string instead of string? in all places in your code.

The Nullable<T> type requires that T is a non-nullable value type, for example int or DateTime. Reference types like string can already be null. There would be no point in allowing things like Nullable<string> so it is disallowed.

Also if you are using C# 3.0 or later you can simplify your code by using auto-implemented properties:

public class WordAndMeaning
{
    public string Word { get; set; }
    public string Meaning { get; set; }
}

Facebook Research group released a new solution called InferSent Results and code are published on Github, check their repo. It is pretty awesome. I am planning to use it. https://github.com/facebookresearch/InferSent

their paper https://arxiv.org/abs/1705.02364 Abstract: Many modern NLP systems rely on word embeddings, previously trained in an unsupervised manner on large corpora, as base features. Efforts to obtain embeddings for larger chunks of text, such as sentences, have however not been so successful. Several attempts at learning unsupervised representations of sentences have not reached satisfactory enough performance to be widely adopted. In this paper, we show how universal sentence representations trained using the supervised data of the Stanford Natural Language Inference datasets can consistently outperform unsupervised methods like SkipThought vectors on a wide range of transfer tasks. Much like how computer vision uses ImageNet to obtain features, which can then be transferred to other tasks, our work tends to indicate the suitability of natural language inference for transfer learning to other NLP tasks. Our encoder is publicly available.

Just add position:absolute; top:0; right:0; to the CSS for your button.

 #button {
     line-height: 12px;
     width: 18px;
     font-size: 8pt;
     font-family: tahoma;
     margin-top: 1px;
     margin-right: 2px;
     position:absolute;
     top:0;
     right:0;
 }

jsFiddle example

/<b>(.*?)<\/b>/g

Add g (global) flag after:

/<b>(.*?)<\/b>/g.exec(str)
             //^-----here it is 

However if you want to get all matched elements, then you need something like this:

var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
   return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"] 

If an element has attributes, regexp will be:

/<b [^>]+>(.*?)<\/b>/g.exec(str)

Loop through elements in the list and update the total like this:

def sum(a):
    total = 0
    index = 0
    while index < len(a):
        total = total + a[index]
        index = index + 1
    return total

Whenever there are issues of mismatched axis limits, the right tool in base graphics is to use matplot. The key is to leverage the from and to arguments to density.default. It's a bit hackish, but fairly straightforward to roll yourself:

set.seed(102349)
x1 = rnorm(1000, mean = 5, sd = 3)
x2 = rnorm(5000, mean = 2, sd = 8)

xrng = range(x1, x2)

#force the x values at which density is
#  evaluated to be the same between 'density'
#  calls by specifying 'from' and 'to'
#  (and possibly 'n', if you'd like)
kde1 = density(x1, from = xrng[1L], to = xrng[2L])
kde2 = density(x2, from = xrng[1L], to = xrng[2L])

matplot(kde1$x, cbind(kde1$y, kde2$y))

Add bells and whistles as desired (matplot accepts all the standard plot/par arguments, e.g. lty, type, col, lwd, ...).

There is more than one way to do this.

Here is a good resource straight from Google: http://developer.android.com/training/basics/firstapp/starting-activity.html

At developer.android.com, they have numerous tutorials explaining just about everything you need to know about android. They even provide detailed API for each class.

If that doesn't help, there are NUMEROUS different resources that can help you with this question and other android questions.

"Is the order of elements in a JSON list maintained?" is not a good question. You need to ask "Is the order of elements in a JSON list maintained when doing [...] ?" As Felix King pointed out, JSON is a textual data format. It doesn't mutate without a reason. Do not confuse a JSON string with a (JavaScript) object.

You're probably talking about operations like JSON.stringify(JSON.parse(...)). Now the answer is: It depends on the implementation. 99%* of JSON parsers do not maintain the order of objects, and do maintain the order of arrays, but you might as well use JSON to store something like

{
    "son": "David",
    "daughter": "Julia",
    "son": "Tom",
    "daughter": "Clara"
}

and use a parser that maintains order of objects.

_{*probably even more :)}

Check you routes, the update on 9/28/2014 impacted us. We had to adjust our older servers and add new routes. Here is the article http://www.rackspace.com/knowledge_center/article/updating-servicenet-routes-on-cloud-servers-created-before-june-3-2013

When you use scp you have to tell the host name and ip address from where you want to copy the file. For instance, if you are at the remote host and you want to transfer the file to your pc you may use something like this:

scp -P[portnumber] myfile_at_remote_host [user]@[your_ip_address]:/your/path/

Example:

scp -P22 table [email protected]:/home/me/Desktop/

On the other hand, if you are at your are actually on your machine you may use something like this:

scp -P[portnumber] [remote_login]@[remote's_ip_address]:/remote/path/myfile_at_remote_host /your/path/

Example:

scp -P22 [fake_user]@222.222.222.222:/remote/path/table /home/me/Desktop/

ES6 based code:

let handleMousemove = (event) => {
  console.log(`mouse position: ${event.x}:${event.y}`);
};

document.addEventListener('mousemove', handleMousemove);

If you need throttling for mousemoving, use this:

let handleMousemove = (event) => {
  console.warn(`${event.x}:${event.y}\n`);
};

let throttle = (func, delay) => {
  let prev = Date.now() - delay;
  return (...args) => {
    let current = Date.now();
    if (current - prev >= delay) {
      prev = current;
      func.apply(null, args);
    }
  }
};

// let's handle mousemoving every 500ms only
document.addEventListener('mousemove', throttle(handleMousemove, 500));

here is example

To enable USB Debugging first you need to enable Developer Options.

1. Open Zenfone Settings and scroll down and tap About.

2. Scroll down and select Software Information.

3. Under Software information you will see Build Number.

4. Tap Build Number 7 times to enable Developer Options.

5. Come back to Settings and scroll down to find Developer Options.

6. Tap on Developer Options and it will open upto give you option to enable USB Debugging

With Selenium2Library you can use get_source()

import Selenium2Library
s = Selenium2Library.Selenium2Library()
s.open_browser("localhost:7080", "firefox")
source = s.get_source()

Here is the PHP code to check if 'id' parameter exists in the URL or not:

if(isset($_GET['id']))
{
   $slide = $_GET['id'] // Getting parameter value inside PHP variable
}

I hope it will help you.

If the date is given in a fixed form, you can simply use a regular expression to extract the date and "datetime.datetime.strptime" to parse the date:

import re
from datetime import datetime

match = re.search(r'\d{4}-\d{2}-\d{2}', text)
date = datetime.strptime(match.group(), '%Y-%m-%d').date()

Otherwise, if the date is given in an arbitrary form, you can't extract it easily.

You can use any of the following way based on Service Name or SID whatever you have.

With SID:

import cx_Oracle
dsn_tns = cx_Oracle.makedsn('server', 'port', 'sid')
conn = cx_Oracle.connect(user='username', password='password', dsn=dsn_tns)
c = conn.cursor()
c.execute('select count(*) from TABLE_NAME')
for row in c:
   print(row)
conn.close()

OR

With Service Name:

import cx_Oracle
dsn_tns = cx_Oracle.makedsn('server', 'port', service_name='service_name')
conn = cx_Oracle.connect(user='username', password='password', dsn=dsn_tns)
c = conn.cursor()
c.execute('select count(*) from TABLE_NAME')
for row in c:
   print(row)
conn.close()

First you better set debug to TRUE:

$email->SMTPDebug = true;

Or temporary change value of public $SMTPDebug = false; in PHPMailer class.

And then you can see the full log in the browser. For me it was too many emails per second:

...
SMTP -> FROM SERVER:XXX.XX.XX.X Ok
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> get_lines(): $data is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> FROM SERVER:XXX.XX.XX.X Requested action not taken: too many emails per second
SMTP -> ERROR: DATA command not accepted from server: 550 5.7.0 Requested action not taken: too many emails per second
...

Thus I got to know what was the exact issue.

what are Access Specifiers?

There are 3 access specifiers for a class/struct/Union in C++. These access specifiers define how the members of the class can be accessed. Of course, any member of a class is accessible within that class(Inside any member function of that same class). Moving ahead to type of access specifiers, they are:

Public - The members declared as Public are accessible from outside the Class through an object of the class.

Protected - The members declared as Protected are accessible from outside the class BUT only in a class derived from it.

Private - These members are only accessible from within the class. No outside Access is allowed.

An Source Code Example:

class MyClass
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

int main()
{
    MyClass obj;
    obj.a = 10;     //Allowed
    obj.b = 20;     //Not Allowed, gives compiler error
    obj.c = 30;     //Not Allowed, gives compiler error
}

Inheritance and Access Specifiers

Inheritance in C++ can be one of the following types:

• Private Inheritance
• Public Inheritance
• Protected inheritance

Here are the member access rules with respect to each of these:

First and most important rule Private members of a class are never accessible from anywhere except the members of the same class.

Public Inheritance:

All Public members of the Base Class become Public Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

i.e. No change in the Access of the members. The access rules we discussed before are further then applied to these members.

Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:public Base
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Allowed
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Private Inheritance:

All Public members of the Base Class become Private Members of the Derived class &
All Protected members of the Base Class become Private Members of the Derived Class.

An code Example:

Class Base
{
    public:
      int a;
    protected:
      int b;
    private:
      int c;
};

class Derived:private Base   //Not mentioning private is OK because for classes it  defaults to private 
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Not Allowed, Compiler Error, a is private member of Derived now
        b = 20;  //Not Allowed, Compiler Error, b is private member of Derived now
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error

}

Protected Inheritance:

All Public members of the Base Class become Protected Members of the derived class &
All Protected members of the Base Class become Protected Members of the Derived Class.

A Code Example:

Class Base
{
    public:
        int a;
    protected:
        int b;
    private:
        int c;
};

class Derived:protected Base  
{
    void doSomething()
    {
        a = 10;  //Allowed 
        b = 20;  //Allowed
        c = 30;  //Not Allowed, Compiler Error
    }
};

class Derived2:public Derived
{
    void doSomethingMore()
    {
        a = 10;  //Allowed, a is protected member inside Derived & Derived2 is public derivation from Derived, a is now protected member of Derived2
        b = 20;  //Allowed, b is protected member inside Derived & Derived2 is public derivation from Derived, b is now protected member of Derived2
        c = 30;  //Not Allowed, Compiler Error
    }
};

int main()
{
    Derived obj;
    obj.a = 10;  //Not Allowed, Compiler Error
    obj.b = 20;  //Not Allowed, Compiler Error
    obj.c = 30;  //Not Allowed, Compiler Error
}

Remember the same access rules apply to the classes and members down the inheritance hierarchy.

Important points to note:

- Access Specification is per-Class not per-Object

Note that the access specification C++ work on per-Class basis and not per-object basis.
A good example of this is that in a copy constructor or Copy Assignment operator function, all the members of the object being passed can be accessed.

- A Derived class can only access members of its own Base class

Consider the following code example:

class Myclass
{ 
    protected: 
       int x; 
}; 

class derived : public Myclass
{
    public: 
        void f( Myclass& obj ) 
        { 
            obj.x = 5; 
        } 
};

int main()
{
    return 0;
}

It gives an compilation error:

prog.cpp:4: error: ‘int Myclass::x’ is protected

Because the derived class can only access members of its own Base Class. Note that the object obj being passed here is no way related to the derived class function in which it is being accessed, it is an altogether different object and hence derived member function cannot access its members.

What is a friend? How does friend affect access specification rules?

You can declare a function or class as friend of another class. When you do so the access specification rules do not apply to the friended class/function. The class or function can access all the members of that particular class.

So do friends break Encapsulation?

No they don't, On the contrary they enhance Encapsulation!

friendship is used to indicate a intentional strong coupling between two entities.
If there exists a special relationship between two entities such that one needs access to others private or protected members but You do not want everyone to have access by using the public access specifier then you should use friendship.

In order to read a csv in that doesn't have a header and for only certain columns you need to pass params header=None and usecols=[3,6] for the 4th and 7th columns:

df = pd.read_csv(file_path, header=None, usecols=[3,6])

U may do as I have written from my deleted account (ban for new posts :( there was). Its rather simple and nice looking.

Im using 3-rd one of these 3 ones usually, also I wasny checking 1 and 2 version.

from matplotlib.pyplot import cm
import numpy as np

#variable n should be number of curves to plot (I skipped this earlier thinking that it is obvious when looking at picture - sorry my bad mistake xD): n=len(array_of_curves_to_plot)
#version 1:

color=cm.rainbow(np.linspace(0,1,n))
for i,c in zip(range(n),color):
   ax1.plot(x, y,c=c)

#or version 2: - faster and better:

color=iter(cm.rainbow(np.linspace(0,1,n)))
c=next(color)
plt.plot(x,y,c=c)

#or version 3:

color=iter(cm.rainbow(np.linspace(0,1,n)))
for i in range(n):
   c=next(color)
   ax1.plot(x, y,c=c)

example of 3:

Ship RAO of Roll vs Ikeda damping in function of Roll amplitude A44

Citing the official javadoc of List.addAll:

Appends all of the elements in the specified collection to the end of
this list, in the order that they are returned by the specified
collection's iterator (optional operation).  The behavior of this
operation is undefined if the specified collection is modified while
the operation is in progress.  (Note that this will occur if the
specified collection is this list, and it's nonempty.)

So you will copy the references of the objects in list to anotherList. Any method that does not operate on the referenced objects of anotherList (such as removal, addition, sorting) is local to it, and therefore will not influence list.

I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

https://www.tutorialsteacher.com/mvc/htmlhelper-dropdownlist-dropdownlistfor

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:

yourRecord.FieldName = Request.Form["FieldNameInModel"];

As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.

No, I did not dig down to see how th4e magic works under the covers. I just know it works...

I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.

request.getParameterValues("select2") returns an array of all submitted values.

The best way to load an image is through the ImageIO API

BufferedImage img = ImageIO.read(new File("/path/to/some/image"));

There are a number of ways you can render an image to the screen.

You could use a JLabel. This is the simplest method if you don't want to modify the image in anyway...

JLabel background = new JLabel(new ImageIcon(img));

Then simply add it to your window as you see fit. If you need to add components to it, then you can simply set the label's layout manager to whatever you need and add your components.

If, however, you need something more sophisticated, need to change the image somehow or want to apply additional effects, you may need to use custom painting.

First cavert: Don't ever paint directly to a top level container (like JFrame). Top level containers aren't double buffered, so you may end up with some flashing between repaints, other objects live on the window, so changing it's paint process is troublesome and can cause other issues and frames have borders which are rendered inside the viewable area of the window...

Instead, create a custom component, extending from something like JPanel. Override it's paintComponent method and render your output to it, for example...

protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    g.drawImage(img, 0, 0, this);
}

Take a look at Performing Custom Painting and 2D Graphics for more details

As already mentioned by others, & is a logical AND operator and && is a short-circuit AND operator. They differ in how the operands are evaluated as well as whether or not they operate on arrays or scalars:

• & (AND operator) and | (OR operator) can operate on arrays in an element-wise fashion.
• && and || are short-circuit versions for which the second operand is evaluated only when the result is not fully determined by the first operand. These can only operate on scalars, not arrays.

Use a normalised colour histogram. (Read the section on applications here), they are commonly used in image retrieval/matching systems and are a standard way of matching images that is very reliable, relatively fast and very easy to implement.

Essentially a colour histogram will capture the colour distribution of the image. This can then be compared with another image to see if the colour distributions match.

This type of matching is pretty resiliant to scaling (once the histogram is normalised), and rotation/shifting/movement etc.

Avoid pixel-by-pixel comparisons as if the image is rotated/shifted slightly it may lead to a large difference being reported.

Histograms would be straightforward to generate yourself (assuming you can get access to pixel values), but if you don't feel like it, the OpenCV library is a great resource for doing this kind of stuff. Here is a powerpoint presentation that shows you how to create a histogram using OpenCV.

If you run the following in SQL Server, you'll notice that COUNT(1) is evaluated as COUNT(*) anyway. So it appears that there is no difference, and also that COUNT(*) is the expression most native to the query optimizer:

SET SHOWPLAN_TEXT ON
GO

SELECT COUNT(1)
FROM <table>
GO

SET SHOWPLAN_TEXT OFF
GO

There are a couple of variables to set the max number of connections. Most likely, you're running out of file numbers first. Check ulimit -n. After that, there are settings in /proc, but those default to the tens of thousands.

More importantly, it sounds like you're doing something wrong. A single TCP connection ought to be able to use all of the bandwidth between two parties; if it isn't:

• Check if your TCP window setting is large enough. Linux defaults are good for everything except really fast inet link (hundreds of mbps) or fast satellite links. What is your bandwidth*delay product?
• Check for packet loss using ping with large packets (ping -s 1472 ...)
• Check for rate limiting. On Linux, this is configured with tc
• Confirm that the bandwidth you think exists actually exists using e.g., iperf
• Confirm that your protocol is sane. Remember latency.
• If this is a gigabit+ LAN, can you use jumbo packets? Are you?

Possibly I have misunderstood. Maybe you're doing something like Bittorrent, where you need lots of connections. If so, you need to figure out how many connections you're actually using (try netstat or lsof). If that number is substantial, you might:

• Have a lot of bandwidth, e.g., 100mbps+. In this case, you may actually need to up the ulimit -n. Still, ~1000 connections (default on my system) is quite a few.
• Have network problems which are slowing down your connections (e.g., packet loss)
• Have something else slowing you down, e.g., IO bandwidth, especially if you're seeking. Have you checked iostat -x?

Also, if you are using a consumer-grade NAT router (Linksys, Netgear, DLink, etc.), beware that you may exceed its abilities with thousands of connections.

I hope this provides some help. You're really asking a networking question.

Just give the individual button elements a unique name. When pressed, the button's name is available as a request parameter the usual way like as with input elements.

You only need to make sure that the button inputs have type="submit" as in <input type="submit"> and <button type="submit"> and not type="button", which only renders a "dead" button purely for onclick stuff and all.

E.g.

<form action="${pageContext.request.contextPath}/myservlet" method="post">
    <input type="submit" name="button1" value="Button 1" />
    <input type="submit" name="button2" value="Button 2" />
    <input type="submit" name="button3" value="Button 3" />
</form>

with

@WebServlet("/myservlet")
public class MyServlet extends HttpServlet {

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        MyClass myClass = new MyClass();

        if (request.getParameter("button1") != null) {
            myClass.method1();
        } else if (request.getParameter("button2") != null) {
            myClass.method2();
        } else if (request.getParameter("button3") != null) {
            myClass.method3();
        } else {
            // ???
        }

        request.getRequestDispatcher("/WEB-INF/some-result.jsp").forward(request, response);
    }

}

Alternatively, use <button type="submit"> instead of <input type="submit">, then you can give them all the same name, but an unique value. The value of the <button> won't be used as label, you can just specify that yourself as child.

E.g.

<form action="${pageContext.request.contextPath}/myservlet" method="post">
    <button type="submit" name="button" value="button1">Button 1</button>
    <button type="submit" name="button" value="button2">Button 2</button>
    <button type="submit" name="button" value="button3">Button 3</button>
</form>

with

@WebServlet("/myservlet")
public class MyServlet extends HttpServlet {

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        MyClass myClass = new MyClass();
        String button = request.getParameter("button");

        if ("button1".equals(button)) {
            myClass.method1();
        } else if ("button2".equals(button)) {
            myClass.method2();
        } else if ("button3".equals(button)) {
            myClass.method3();
        } else {
            // ???
        }

        request.getRequestDispatcher("/WEB-INF/some-result.jsp").forward(request, response);
    }

}

The simple and best solution is to use tables for layouts. You're doing it right. There are a number of reasons tables are better.

• They perform better than CSS
• They work on all browsers without any fuss
• You can debug them easily with the border=1 attribute

For me works the next command:

find /path/to/dir -name "file.txt" | xargs sed -i 's/string_to_replace/new_string/g'

if string contains slash 'path/to/dir' it can be replace with another character to separate, like '@' instead '/'.

For example: 's@string/to/replace@new/string@g'

// We can apply `slice` from  `Array.prototype`:
Array.prototype.slice.call([]); //-> []

// Since `slice` is available on an array's prototype chain,
'slice' in []; //-> true
[].slice === Array.prototype.slice; //-> true

// … we can just invoke it directly:
[].slice(); //-> []

// `arguments` has no `slice` method
'slice' in arguments; //-> false

// … but we can apply it the same way:
Array.prototype.slice.call(arguments); //-> […]

// In fact, though `slice` belongs to `Array.prototype`,
// it can operate on any array-like object:
Array.prototype.slice.call({0: 1, length: 1}); //-> [1]

There's another, very secure method. It's client certificates. Know how servers present an SSL Cert when you contact them on https? Well servers can request a cert from a client so they know the client is who they say they are. Clients generate certs and give them to you over a secure channel (like coming into your office with a USB key - preferably a non-trojaned USB key).

You load the public key of the cert client certificates (and their signer's certificate(s), if necessary) into your web server, and the web server won't accept connections from anyone except the people who have the corresponding private keys for the certs it knows about. It runs on the HTTPS layer, so you may even be able to completely skip application-level authentication like OAuth (depending on your requirements). You can abstract a layer away and create a local Certificate Authority and sign Cert Requests from clients, allowing you to skip the 'make them come into the office' and 'load certs onto the server' steps.

Pain the neck? Absolutely. Good for everything? Nope. Very secure? Yup.

It does rely on clients keeping their certificates safe however (they can't post their private keys online), and it's usually used when you sell a service to clients rather then letting anyone register and connect.

Anyway, it may not be the solution you're looking for (it probably isn't to be honest), but it's another option.

  .buttonDisabled{
     background-color: unset !important;
    color: unset !important;
}

Since nullptr is never going to be returned, I recommend the reference approach. It more accurately represents how the return value will be used.

There might be a reason that Typescript is not installed globally, so install it

npm install -g typescript // installs typescript globally

If you want to convert .ts files into .js, do this as per your need

tsc file.ts // file.ts will be converted to file.js file
tsc         // all .ts files will be converted to .js files in the directory
tsc --watch // converts all .ts files to .js, and watch changes in .ts files

As the "GNU C Library Reference Manual" says

off_t
    This is a signed integer type used to represent file sizes. 
    In the GNU C Library, this type is no narrower than int.
    If the source is compiled with _FILE_OFFSET_BITS == 64 this 
    type is transparently replaced by off64_t.

and

off64_t
    This type is used similar to off_t. The difference is that 
    even on 32 bit machines, where the off_t type would have 32 bits,
    off64_t has 64 bits and so is able to address files up to 2^63 bytes
    in length. When compiling with _FILE_OFFSET_BITS == 64 this type 
    is available under the name off_t.

Thus if you want reliable way of representing file size between client and server, you can:

1. Use off64_t type and stat64() function accordingly (as it fills structure stat64, which contains off64_t type itself). Type off64_t guaranties the same size on 32 and 64 bit machines.
2. As was mentioned before compile your code with -D_FILE_OFFSET_BITS == 64 and use usual off_t and stat().
3. Convert off_t to type int64_t with fixed size (C99 standard). Note: (my book 'C in a Nutshell' says that it is C99 standard, but optional in implementation). The newest C11 standard says:

7.20.1.1 Exact-width integer types

    1 The typedef name intN_t designates a signed integer type with width N ,
    no padding bits, and a two’s complement representation. Thus, int8_t 
    denotes such a signed integer type with a width of exactly 8 bits.
    without mentioning.

And about implementation:

7.20 Integer types <stdint.h>

    ... An implementation shall provide those types described as ‘‘required’’,
    but need not provide any of the others (described as ‘‘optional’’).
    ...
    The following types are required:
    int_least8_t  uint_least8_t
    int_least16_t uint_least16_t
    int_least32_t uint_least32_t
    int_least64_t uint_least64_t
    All other types of this form are optional.

Thus, in general, C standard can't guarantee types with fixed sizes. But most compilers (including gcc) support this feature.

One of the possible way to do it:

import urllib
...

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    # Python 3
    from urllib.request import urlopen

You can also use callto:########### replacing the email code mail with call, at least according to W3Cschool site but I haven't had an opportunity to test it out.

On Android >=6.0, We have to request permission runtime.

Step1: add in AndroidManifest.xml file

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

Step2: Request permission.

int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);

if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE_STATE);
} else {
    //TODO
}

Step3: Handle callback when you request permission.

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_READ_PHONE_STATE:
            if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
                //TODO
            }
            break;

        default:
            break;
    }
}

Edit: Read official guide here Requesting Permissions at Run Time

The simplest way is with the pkill command. In your case:

pkill -9 -t pts/6
pkill -9 -t pts/9
pkill -9 -t pts/10

Regarding tty sessions, the commands below are always useful:

w - shows active terminal sessions

tty - shows your current terminal session (so you won't close it by accident)

last | grep logged - shows currently logged users

Sometimes we want to close all sessions of an idle user (ie. when connections are lost abruptly).

pkill -u username - kills all sessions of 'username' user.

And sometimes when we want to kill all our own sessions except the current one, so I made a script for it. There are some cosmetics and some interactivity (to avoid accidental running on the script).

#!/bin/bash
MYUSER=`whoami`
MYSESSION=`tty | cut -d"/" -f3-`
OTHERSESSIONS=`w $MYUSER | grep "^$MYUSER" | grep -v "$MYSESSION" | cut -d" " -f2`
printf "\e[33mCurrent session\e[0m: $MYUSER[$MYSESSION]\n"

if [[ ! -z $OTHERSESSIONS ]]; then
  printf "\e[33mOther sessions:\e[0m\n"
  w $MYUSER | egrep "LOGIN@|^$MYUSER" | grep -v "$MYSESSION" | column -t
  echo ----------
  read -p "Do you want to force close all your other sessions? [Y]Yes/[N]No: " answer
  answer=`echo $answer | tr A-Z a-z`
  confirm=("y" "yes")

  if [[ "${confirm[@]}" =~ "$answer" ]]; then
  for SESSION in $OTHERSESSIONS
    do
         pkill -9 -t $SESSION
         echo Session $SESSION closed.
    done
  fi
else
        echo "There are no other sessions for the user '$MYUSER'".
fi

import json, ast
r = {u'name': u'A', u'primary_key': 1}
ast.literal_eval(json.dumps(r)) 

will print

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

Its undefined because, console.log(response) runs before doCall(urlToCall); is finished. You have to pass in a callback function aswell, that runs when your request is done.

First, your function. Pass it a callback:

function doCall(urlToCall, callback) {
    urllib.request(urlToCall, { wd: 'nodejs' }, function (err, data, response) {                              
        var statusCode = response.statusCode;
        finalData = getResponseJson(statusCode, data.toString());
        return callback(finalData);
    });
}

Now:

var urlToCall = "http://myUrlToCall";
doCall(urlToCall, function(response){
    // Here you have access to your variable
    console.log(response);
})

@Rodrigo, posted a good resource in the comments. Read about callbacks in node and how they work. Remember, it is asynchronous code.

Yes even I got the same error. So I did the following changes

-> Check the error in the Problems tab located near the Console tab

-> See where the error persists, Its possible that some jar file may be corrupted or is outdated so, pom isn't activated in the Project.

-> I found one of my jar was outdated version so I updated it by getting the dependencies from maven repository from this link https://mvnrepository.com

So to conclude, do check where the error persist and which jar file is outdated and make changes accordingly

If data frame fits in a driver memory and you want to save to local files system you can convert Spark DataFrame to local Pandas DataFrame using toPandas method and then simply use to_csv:

df.toPandas().to_csv('mycsv.csv')

Otherwise you can use spark-csv:

• Spark 1.3

  df.save('mycsv.csv', 'com.databricks.spark.csv')
  

• Spark 1.4+

  df.write.format('com.databricks.spark.csv').save('mycsv.csv')
  

In Spark 2.0+ you can use csv data source directly:

df.write.csv('mycsv.csv')

Make outer <div> to position: relative and inner <div> to position: absolute. It should work for you.

You can use slice() for this:

>> foo = [1,2,3,4,5,6]
=> [1, 2, 3, 4, 5, 6]
>> bar = [10,20,30,40,50,60]
=> [10, 20, 30, 40, 50, 60]
>> half = foo.length / 2
=> 3
>> foobar = foo.slice(0, half) + bar.slice(half, foo.length)
=> [1, 2, 3, 40, 50, 60]

By the way, to the best of my knowledge, Python "lists" are just efficiently implemented dynamically growing arrays. Insertion at the beginning is in O(n), insertion at the end is amortized O(1), random access is O(1).

Use SimpleDateFormat for Android N and above. Use the calendar for earlier versions for example:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        fileName = new SimpleDateFormat("yyyy-MM-dd-hh:mm:ss").format(new Date());
        Log.i("fileName before",fileName);
    }else{

        cal.add(Calendar.MONTH,1);
        String zamanl =""+cal.get(Calendar.YEAR)+"-"+cal.get(Calendar.MONTH)+"-"+cal.get(Calendar.DAY_OF_MONTH)+"-"+cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE)+":"+cal.get(Calendar.SECOND);

        fileName= zamanl;
        Log.i("fileName after",fileName);
    }

Output:
fileName before: 2019-04-12-07:14:47  // use SimpleDateFormat
fileName after: 2019-4-12-7:13:12        // use Calender

I know that this is an old question, but as I was googling it was the first link in a results. So here is the jsp solution:

<form action="some.jsp">
  <select name="item">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
  </select>
  <input type="submit" value="Submit">
</form>

in some.jsp

request.getParameter("item");

this line will return the selected option (from the example it is: 1, 2 or 3)
