Zookeeper is just a Java process and when you start a Zookeeper instance it runs a org.apache.zookeeper.server.quorum.QuorumPeerMain class. So you can check for a running Zookeeper like this:

jps -l | grep zookeeper

or even like this:

jps | grep Quorum

upd:

regarding this: will hostname be the hostname of my box?? - the answer is yes.

Using top and ps is okay, but I find that using htop is far better & clearer than the standard tools Mac OS X uses. My fave use is to hit the T key while it is running to view processes in tree view (see screenshot). Shows you what processes are co-dependent on other processes.

You can install it from Homebrew using:

brew install htop

And if you have Xcode and related tools such as git installed on your system and you want to install the latest development code from the official source repository—just follow these steps.

First clone the source code from the htop GitHub repository:

git clone [email protected]:hishamhm/htop.git

Now go into the repository directory:

cd htop

Run autogen.sh:

./autogen.sh

Run this configure command:

./configure

Once the configure process completes, run make:

make

Finally install it by running sudo make install:

sudo make install

If you want to execute that command, you should probably change:

PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'

to:

PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)

You can use the fuser command, like:

fuser file_name

You will receive a list of processes using the file.

You can use different flags with it, in order to receive a more detailed output.

You can find more info in the fuser's Wikipedia article, or in the man pages.

My issue was a missing set of quotes;

Foo: bar 'baz'

should be

Foo: "bar 'baz'"

I have no idea why the HttpURLConnection class does not provide any means to send files without having to compose the file wrapper manually. Here's what I ended up doing, but if someone knows a better solution, please let me know.

Input data:

Bitmap bitmap = myView.getBitmap();

Static stuff:

String attachmentName = "bitmap";
String attachmentFileName = "bitmap.bmp";
String crlf = "\r\n";
String twoHyphens = "--";
String boundary =  "*****";

Setup the request:

HttpURLConnection httpUrlConnection = null;
URL url = new URL("http://example.com/server.cgi");
httpUrlConnection = (HttpURLConnection) url.openConnection();
httpUrlConnection.setUseCaches(false);
httpUrlConnection.setDoOutput(true);

httpUrlConnection.setRequestMethod("POST");
httpUrlConnection.setRequestProperty("Connection", "Keep-Alive");
httpUrlConnection.setRequestProperty("Cache-Control", "no-cache");
httpUrlConnection.setRequestProperty(
    "Content-Type", "multipart/form-data;boundary=" + this.boundary);

Start content wrapper:

DataOutputStream request = new DataOutputStream(
    httpUrlConnection.getOutputStream());

request.writeBytes(this.twoHyphens + this.boundary + this.crlf);
request.writeBytes("Content-Disposition: form-data; name=\"" +
    this.attachmentName + "\";filename=\"" + 
    this.attachmentFileName + "\"" + this.crlf);
request.writeBytes(this.crlf);

Convert Bitmap to ByteBuffer:

//I want to send only 8 bit black & white bitmaps
byte[] pixels = new byte[bitmap.getWidth() * bitmap.getHeight()];
for (int i = 0; i < bitmap.getWidth(); ++i) {
    for (int j = 0; j < bitmap.getHeight(); ++j) {
        //we're interested only in the MSB of the first byte, 
        //since the other 3 bytes are identical for B&W images
        pixels[i + j] = (byte) ((bitmap.getPixel(i, j) & 0x80) >> 7);
    }
}

request.write(pixels);

End content wrapper:

request.writeBytes(this.crlf);
request.writeBytes(this.twoHyphens + this.boundary + 
    this.twoHyphens + this.crlf);

Flush output buffer:

request.flush();
request.close();

Get response:

InputStream responseStream = new 
    BufferedInputStream(httpUrlConnection.getInputStream());

BufferedReader responseStreamReader = 
    new BufferedReader(new InputStreamReader(responseStream));

String line = "";
StringBuilder stringBuilder = new StringBuilder();

while ((line = responseStreamReader.readLine()) != null) {
    stringBuilder.append(line).append("\n");
}
responseStreamReader.close();

String response = stringBuilder.toString();

Close response stream:

responseStream.close();

Close the connection:

httpUrlConnection.disconnect();

PS: Of course I had to wrap the request in private class AsyncUploadBitmaps extends AsyncTask<Bitmap, Void, String>, in order to make the Android platform happy, because it doesn't like to have network requests on the main thread.

Another implementation but without any overflow on tbody and dynamic columns. Requires JavaScript though. A container div is used to house the column headings. When the table is scrolled past the view port, a fixed header appears at the top. If table is scrolled horizontally, the fixed header scrolls as well.

Column headings are created using span elements with display: inline-block and a negative margin is used to scroll header horizontally. Also optimized using RequestAnimationFrame to avoid any jank.

function rAF(scrollLeft) {
  var offsetLeft = 0 - scrollLeft;
  $('.hdr__inner span:first-child').css('margin-left', offsetLeft);
}

I have faced this issue, my certificates where having private key but i was getting this error("Keyset does not exist")

Cause: Your web site is running under "Network services" account or having less privileges.

Solution: Change Application pool identity to "Local System", reset IIS and check again. If it starts working it is permission/Less privilege issue, you can impersonate then using other accounts too.

Ok in intelliJ 14 Ultimate using the Mac version this is it.

Windows start up menu,Search for windows credential manager. Search for bitbucket url, Try updating password there.. and do git operation again. It should work.

You can add button in toolbar

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        app:title="title">

        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="right"
            android:layout_marginRight="16dp"
            android:background="@color/transparent"
            android:drawableRight="@drawable/ic_your_icon"
            android:drawableTint="@drawable/btn_selector"
            android:text="@string/sort_by_credit"
            android:textColor="@drawable/btn_selector"
            />

    </android.support.v7.widget.Toolbar>

create file btn_selector.xml in drawable

<?xml version="1.0" encoding="utf-8" ?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item
    android:state_selected="true"
    android:color="@color/white"
    />
<item
    android:color="@color/white_30_opacity"
    />

java:

private boolean isSelect = false;

OnClickListener for button:

private void myClick() {
    if (!isSelect) {
       //**your code**//
        isSelect = true;
    } else {//**your code**//
        isSelect = false;
    }
    sort.setSelected(isSelect);
}

Add include_directories("/your/path/here").

This will be similar to calling gcc with -I/your/path/here/ option.

Make sure you put double quotes around the path. Other people didn't mention that and it made me stuck for 2 days. So this answer is for people who are very new to CMake and very confused.

As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

int[] ret = new int[list.size()];       
Iterator<Integer> iter = list.iterator();
for (int i=0; iter.hasNext(); i++) {       
    ret[i] = iter.next();                
}                                        
return ret;                              

import os#must import this library
if os.path.exists('TwitterDB.csv'):
        os.remove('TwitterDB.csv') #this deletes the file
else:
        print("The file does not exist")#add this to prevent errors

I had a similar problem, and instead of overwriting my existing file using the different 'modes', I just deleted the file before using it again, so that it would be as if I was appending to a new file on each run of my code.

This code:

"127.0.0.1".equals(InetAddress.getLocalHost().getHostAddress().toString());

Returns - to me - true if offline, and false, otherwise. (well, I don't know if this true to all computers).

This works much faster than the other approaches, up here.

EDIT: I found this only working, if the "flip switch" (on a laptop), or some other system-defined option, for the internet connection, is off. That's, the system itself knows not to look for any IP addresses.

I have commented my this code : // $('#description').val('<?php echo $_POST['description']; ?>'); and I got that error.

I just got the solution to this problem from a friend. he said: Add ob_start(); under your session code. You can add exit(); under the header. I tried it and it worked. Hope this helps

This is for those on a rented Hosting sever who do not have access to php.init file.

If you want short, human-readable IDs and only need them to be unique per JVM run:

private static long idCounter = 0;

public static synchronized String createID()
{
    return String.valueOf(idCounter++);
}    

Edit: Alternative suggested in the comments - this relies on under-the-hood "magic" for thread safety, but is more scalable and just as safe:

private static AtomicLong idCounter = new AtomicLong();

public static String createID()
{
    return String.valueOf(idCounter.getAndIncrement());
}

Or... You can use Blob to achive this.

Like:

pdf.addHTML($('#content'), y, x, options, function () {
    var blob = pdf.output("blob");
    window.open(URL.createObjectURL(blob));
});

That code let you create a Blob object inside the browser and show it in the new tab.

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

List is an interface, not a concrete class.
An interface is just a set of functions that a class can implement; it doesn't make any sense to instantiate an interface.

ArrayList is a concrete class that happens to implement this interface and all of the methods in it.

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

You do not have to install something.

parseInt(req.params.year, 10);

should work properly.

console.log(typeof parseInt(req.params.year)); // returns 'number'

What is your output, if you use parseInt? is it still a string?

As WhirlWind said, you start at the beginning.

You swap cursor with each remaining value, including cursor itself, these are all new instances (I used an int[] and array.clone() in the example).

Then perform permutations on all these different lists, making sure the cursor is one to the right.

When there are no more remaining values (cursor is at the end), print the list. This is the stop condition.

public void permutate(int[] list, int pointer) {
    if (pointer == list.length) {
        //stop-condition: print or process number
        return;
    }
    for (int i = pointer; i < list.length; i++) {
        int[] permutation = (int[])list.clone();.
        permutation[pointer] = list[i];
        permutation[i] = list[pointer];
        permutate(permutation, pointer + 1);
    }
}

Try This

SELECT Title  from #Movies
    SELECT CASE WHEN Title = '' THEN 'No Title' ELSE Title END AS Titile from #Movies

OR

SELECT [Id], [CategoryId], ISNULL(nullif(Title,''),'No data') as Title, [Director], [DateReleased] FROM #Movies

Developing on Windows, I ran into this problem when using git tfs. I solved it this way:

git config --global core.whitespace cr-at-eol

This basically tells Git that an end-of-line CR is not an error. As a result, those annoying ^M characters no longer appear at the end of lines in git diff, git show, etc.

It appears to leave other settings as-is; for instance, extra spaces at the end of a line still show as errors (highlighted in red) in the diff.

(Other answers have alluded to this, but the above is exactly how to set the setting. To set the setting for only one project, omit the --global.)

EDIT:

After many line-ending travails, I've had the best luck, when working on a .NET team, with these settings:

• NO core.eol setting
• NO core.whitespace setting
• NO core.autocrlf setting
• When running the Git installer for Windows, you'll get these three options:
  • Checkout Windows-style, commit Unix-style line endings <-- choose this one
  • Checkout as-is, commit Unix-style line endings
  • Checkout as-is, commit as-is

If you need to use the whitespace setting, you should probably enable it only on a per-project basis if you need to interact with TFS. Just omit the --global:

git config core.whitespace cr-at-eol

If you need to remove some core.* settings, the easiest way is to run this command:

git config --global -e

This opens your global .gitconfig file in a text editor, and you can easily delete the lines you want to remove. (Or you can put '#' in front of them to comment them out.)

Noting down my situation here may be useful to somebody,

I have to send a custom intent with multiple intent extras to a broadcast receiver in Android P,

The details are,

Receiver name: com.hardian.testservice.TestBroadcastReceiver

Intent action = "com.hardian.testservice.ADD_DATA"

intent extras are,

1. "text"="test msg",
2. "source"= 1,

Run the following in command line.

adb shell "am broadcast -a com.hardian.testservice.ADD_DATA --es text 'test msg' --es source 1 -n com.hardian.testservice/.TestBroadcastReceiver"

Hope this helps.

The major difference is

• a INDEX's on Timestamp - works
• a INDEX's on Datetime - Does not work

look at this post to see problems with Datetime indexing

When you need rule based matching, you need to use regex

$string = "REGISTER 11223344 here";
preg_match("/(\d+)/", $string, $match);
$number = $match[1];

That will match the first set of numbers, so if you need to be more specific try:

$string = "REGISTER 11223344 here";
preg_match("/REGISTER (\d+) here/", $string, $match);
$number = $match[1];

instead of onmouseout use onmouseleave.

You haven't showed to us your specific code so I cannot show you on your specific example how to do it.

But it is very simple: just replace onmouseout with onmouseleave.

That's all :) So, simple :)

If not sure how to do it, see explanation on:

https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_onmousemove_leave_out

Peace of cake :) Enjoy it :)

1. Modern C++20 solution

auto cmp = [](int a, int b) { return ... };
std::set<int, decltype(cmp)> s;

We use lambda function as comparator. As usual, comparator should return boolean value, indicating whether the element passed as first argument is considered to go before the second in the specific strict weak ordering it defines.

Online demo

2. Modern C++11 solution

auto cmp = [](int a, int b) { return ... };
std::set<int, decltype(cmp)> s(cmp);

Before C++20 we need to pass lambda as argument to set constructor

Online demo

3. Similar to first solution, but with function instead of lambda

Make comparator as usual boolean function

bool cmp(int a, int b) {
    return ...;
}

Then use it, either this way:

std::set<int, decltype(cmp)*> s(cmp);

Online demo

or this way:

std::set<int, decltype(&cmp)> s(&cmp);

Online demo

4. Old solution using struct with () operator

struct cmp {
    bool operator() (int a, int b) const {
        return ...
    }
};

// ...
// later
std::set<int, cmp> s;

Online demo

5. Alternative solution: create struct from boolean function

Take boolean function

bool cmp(int a, int b) {
    return ...;
}

And make struct from it using std::integral_constant

#include <type_traits>
using Cmp = std::integral_constant<decltype(&cmp), &cmp>;

Finally, use the struct as comparator

std::set<X, Cmp> set;

Online demo

Using the index:

df[1:4,]

Where the values in the parentheses can be interpreted as either logical, numeric, or character (matching the respective names):

df[row.index, column.index]

Read help(`[`) for more detail on this subject, and also read about index matrices in the Introduction to R.

You can use :nth-child(N) CSS selector like :

table td:first-child {}  //1
table td:nth-child(2) {} //2
table td:nth-child(3) {} //3
table td:last-child {}   //4

Simply use something like the following - the string should be there already:

<?php
   if(isset($_SERVER['SERVER_SOFTWARE'])){
      echo $_SERVER['SERVER_SOFTWARE'];
   }
?>

You need to use Range and Value functions.
Range would be the cell where you want the text you want
Value would be the text that you want in that Cell

Range("A1").Value="whatever text"

Use a simple for loop:

seq = ['abc123', 'def456', 'ghi789']
sub = 'abc'

for text in seq:
    if sub in text:
        print(text)

yields

abc123

with this globals variables idea, I saved MainActivity instance in onCreate(); Android global variable

public class ApplicationController extends Application {

    public static MainActivity this_MainActivity;
}

and Open dialog like this. it worked.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Global Var
    globals = (ApplicationController) this.getApplication();
    globals.this_MainActivity = this;
}

and in a thread, I open dialog like this.

AlertDialog.Builder alert = new AlertDialog.Builder(globals.this_MainActivity);

1. Open MainActivity
2. Start a thread.
3. Open dialog from thread -> work.
4. Click "Back button" ( onCreate will be called and remove first MainActivity)
5. New MainActivity will start. ( and save it's instance to globals )
6. Open dialog from first thread --> it will open and work.

Just had same issue. In Python 3, Binary modes 'wb', 'rb' must be specified whereas in Python 2x, they are not needed. When you follow tutorials that are based on Python 2x, that's why you are here.

import pickle

class MyUser(object):
    def __init__(self,name):
        self.name = name

user = MyUser('Peter')

print("Before serialization: ")
print(user.name)
print("------------")
serialized = pickle.dumps(user)
filename = 'serialized.native'

with open(filename,'wb') as file_object:
    file_object.write(serialized)

with open(filename,'rb') as file_object:
    raw_data = file_object.read()

deserialized = pickle.loads(raw_data)


print("Loading from serialized file: ")
user2 = deserialized
print(user2.name)
print("------------")

IT IS NOT IMPOSSIBLE.
Use a reverse proxy server to handle the Different-Origin-Problem. I used to using Nginx with proxy_pass to change the url of page. you can have a try.

Another way is to write a simple proxy page runs on server by yourself, just request from Google and output the result to the client.

I think Michal's answer is the best, but we can take it a step further and dynamically load an Android CSS as per the original question:

var isAndroid = /(android)/i.test(navigator.userAgent);
if (isAndroid) {
    var css = document.createElement("link");
    css.setAttribute("rel", "stylesheet");
    css.setAttribute("type", "text/css");
    css.setAttribute("href", "/css/android.css");
    document.body.appendChild(css);
}

I thinks it is vary helpful way.

You can use

$objWorksheet->getActiveSheet()->getRowDimension('1')->setRowHeight(40);
$objWorksheet->getActiveSheet()->getColumnDimension('A')->setWidth(100);

or define auto-size:

$objWorksheet->getRowDimension('1')->setRowHeight(-1);

I created a library called JColor that works on Linux, macOS, and Windows 10.

It uses the ANSI codes mentioned by WhiteFang, but abstracts them using words instead of codes which is more intuitive. Recently I added support for 8 and 24 bit colors

Choose your format, colorize it, and print it:

System.out.println(colorize("Green text on blue", GREEN_TEXT(), BLUE_BACK()));

You can also define a format once, and reuse it several times:

AnsiFormat fWarning = new AnsiFormat(RED_TEXT(), YELLOW_BACK(), BOLD());
System.out.println(colorize("Something bad happened!", fWarning));

Head over to JColor github repository for some examples.

If you really want to have a blocking (synchronous) delay function (for whatsoever), why not do something like this:

<script type="text/javascript">
    function delay(ms) {
        var cur_d = new Date();
        var cur_ticks = cur_d.getTime();
        var ms_passed = 0;
        while(ms_passed < ms) {
            var d = new Date();  // Possible memory leak?
            var ticks = d.getTime();
            ms_passed = ticks - cur_ticks;
            // d = null;  // Prevent memory leak?
        }
    }

    alert("2 sec delay")
    delay(2000);
    alert("done ... 500 ms delay")
    delay(500);
    alert("done");
</script>

Once I faced with the issue when I did not know which the element currently stored in my variable (svg or html) but I needed to get it width and height. I created this function and want to share it:

function computeDimensions(selection) {
  var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGGraphicsElement) { // check if node is svg element
    dimensions = node.getBBox();
  } else { // else is html element
    dimensions = node.getBoundingClientRect();
  }
  console.log(dimensions);
  return dimensions;
}

Little demo in the hidden snippet below. We handle click on the blue div and on the red svg circle with the same function.

var svg = d3.select('svg')
  .attr('width', 50)
  .attr('height', 50);

function computeDimensions(selection) {
    var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGElement) {
    dimensions = node.getBBox();
  } else {
    dimensions = node.getBoundingClientRect();
  }
  console.clear();
  console.log(dimensions);
  return dimensions;
}

var circle = svg
    .append("circle")
    .attr("r", 20)
    .attr("cx", 30)
    .attr("cy", 30)
    .attr("fill", "red")
    .on("click", function() { computeDimensions(circle); });
    
var div = d3.selectAll("div").on("click", function() { computeDimensions(div) });

* {
  margin: 0;
  padding: 0;
  border: 0;
}

body {
  background: #ffd;
}

.div {
  display: inline-block;
  background-color: blue;
  margin-right: 30px;
  width: 30px;
  height: 30px;
}

<h3>
  Click on blue div block or svg circle
</h3>

Honestly, I was in the same boat as you. I've got a C++ Library that I wanted to connect to a graphing utility. I ended up using Boost Python and matplotlib. It was the best one that I could find.

As a side note: I was also wary of licensing. matplotlib and the boost libraries can be integrated into proprietary applications.

Here's an example of the code that I used:

#include <boost/python.hpp>
#include <pygtk/pygtk.h>
#include <gtkmm.h>

using namespace boost::python;
using namespace std;

// This is called in the idle loop.
bool update(object *axes, object *canvas) {
    static object random_integers = object(handle<>(PyImport_ImportModule("numpy.random"))).attr("random_integers");
    axes->attr("scatter")(random_integers(0,1000,1000), random_integers(0,1000,1000));
    axes->attr("set_xlim")(0,1000);
    axes->attr("set_ylim")(0,1000);
    canvas->attr("draw")();
    return true;
}

int main() {
    try {
        // Python startup code
        Py_Initialize();
        PyRun_SimpleString("import signal");
        PyRun_SimpleString("signal.signal(signal.SIGINT, signal.SIG_DFL)");

        // Normal Gtk startup code
        Gtk::Main kit(0,0);

        // Get the python Figure and FigureCanvas types.
        object Figure = object(handle<>(PyImport_ImportModule("matplotlib.figure"))).attr("Figure");
        object FigureCanvas = object(handle<>(PyImport_ImportModule("matplotlib.backends.backend_gtkagg"))).attr("FigureCanvasGTKAgg");

        // Instantiate a canvas
        object figure = Figure();
        object canvas = FigureCanvas(figure);
        object axes = figure.attr("add_subplot")(111);
        axes.attr("hold")(false);

        // Create our window.
        Gtk::Window window;
        window.set_title("Engineering Sample");
        window.set_default_size(1000, 600);

        // Grab the Gtk::DrawingArea from the canvas.
        Gtk::DrawingArea *plot = Glib::wrap(GTK_DRAWING_AREA(pygobject_get(canvas.ptr())));

        // Add the plot to the window.
        window.add(*plot);
        window.show_all();

        // On the idle loop, we'll call update(axes, canvas).
        Glib::signal_idle().connect(sigc::bind(&update, &axes, &canvas));

        // And start the Gtk event loop.
        Gtk::Main::run(window);

    } catch( error_already_set ) {
        PyErr_Print();
    }
}

If your data has the names grouped as shown then you can use this formula in D2 copied down to get a total against the last entry for each name

=IF((A2=A3)*(B2=B3),"",SUM(C$2:C2)-SUM(D$1:D1))

See screenshot

Non-const and const reference binding follow different rules

These are the rules of the C++ language:

• an expression consisting of a literal number (12) is a "rvalue"
• it is not permitted to create a non-const reference with a rvalue: int &ri = 12; is ill-formed
• it is permitted to create a const reference with a rvalue: in this case, an unnamed object is created by the compiler; this object will persist as long as the reference itself exist.

You have to understand that these are C++ rules. They just are.

It is easy to invent a different language, say C++', with slightly different rules. In C++', it would be permitted to create a non-const reference with a rvalue. There is nothing inconsistent or impossible here.

But it would allow some risky code where the programmer might not get what he intended, and C++ designers rightly decided to avoid that risk.

use text transform property in your style tag

textTransform:'uppercase'

string result = System.Text.Encoding.UTF8.GetString(byteArray);

yes datediff is implemented; see: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF

By the way I found this by Google-searching "hive datediff", it was the first result ;)

your http service file:

import { Injectable } from "@angular/core";
import { ActivatedRoute, Router } from '@angular/router';
import { Http, Headers, Response, Request, RequestMethod, URLSearchParams, RequestOptions } from "@angular/http";
import {Observable} from 'rxjs/Rx';
import { Constants } from './constants';
declare var $: any;

@Injectable()
export class HttpClient {
  requestUrl: string;
  responseData: any;
  handleError: any;

  constructor(private router: Router, 
  private http: Http, 
  private constants: Constants, 
  ) {
    this.http = http;
  }

  postWithFile (url: string, postData: any, files: File[]) {

    let headers = new Headers();
    let formData:FormData = new FormData();
    formData.append('files', files[0], files[0].name);
    // For multiple files
    // for (let i = 0; i < files.length; i++) {
    //     formData.append(`files[]`, files[i], files[i].name);
    // }

    if(postData !=="" && postData !== undefined && postData !==null){
      for (var property in postData) {
          if (postData.hasOwnProperty(property)) {
              formData.append(property, postData[property]);
          }
      }
    }
    var returnReponse = new Promise((resolve, reject) => {
      this.http.post(this.constants.root_dir + url, formData, {
        headers: headers
      }).subscribe(
          res => {
            this.responseData = res.json();
            resolve(this.responseData);
          },
          error => {
            this.router.navigate(['/login']);
            reject(error);
          }
      );
    });
    return returnReponse;
  }
}

call your function (Component file):

onChange(event) {
    let file = event.srcElement.files;
    let postData = {field1:"field1", field2:"field2"}; // Put your form data variable. This is only example.
    this._service.postWithFile(this.baseUrl + "add-update",postData,file).then(result => {
        console.log(result);
    });
}

your html code:

<input type="file" class="form-control" name="documents" (change)="onChange($event)" [(ngModel)]="stock.documents" #documents="ngModel">

Here's a solution which handles multiple path parts and edge conditions:

public static String combinePaths(String ... paths)
{
  if ( paths.length == 0)
  {
    return "";
  }

  File combined = new File(paths[0]);

  int i = 1;
  while ( i < paths.length)
  {
    combined = new File(combined, paths[i]);
    ++i;
  }

  return combined.getPath();
}

Something like this should work (it did for me). The reason for wanting to use -Filter instead of -Include is that include takes a huge performance hit compared to -Filter.

Below just loops each file type and multiple servers/workstations specified in separate files.

##  
##  This script will pull from a list of workstations in a text file and search for the specified string


## Change the file path below to where your list of target workstations reside
## Change the file path below to where your list of filetypes reside

$filetypes = gc 'pathToListOffiletypes.txt'
$servers = gc 'pathToListOfWorkstations.txt'

##Set the scope of the variable so it has visibility
set-variable -Name searchString -Scope 0
$searchString = 'whatYouAreSearchingFor'

foreach ($server in $servers)
    {

    foreach ($filetype in $filetypes)
    {

    ## below creates the search path.  This could be further improved to exclude the windows directory
    $serverString = "\\"+$server+"\c$\Program Files"


    ## Display the server being queried
    write-host “Server:” $server "searching for " $filetype in $serverString

    Get-ChildItem -Path $serverString -Recurse -Filter $filetype |
    #-Include "*.xml","*.ps1","*.cnf","*.odf","*.conf","*.bat","*.cfg","*.ini","*.config","*.info","*.nfo","*.txt" |
    Select-String -pattern $searchstring | group path | select name | out-file f:\DataCentre\String_Results.txt

    $os = gwmi win32_operatingsystem -computer $server
    $sp = $os | % {$_.servicepackmajorversion}
    $a = $os | % {$_.caption}

    ##  Below will list again the server name as well as its OS and SP
    ##  Because the script may not be monitored, this helps confirm the machine has been successfully scanned
        write-host $server “has completed its " $filetype "scan:” “|” “OS:” $a “SP:” “|” $sp

You need to put SongsTableSeeder into file SongsTableSeeder.php in the same directory where you have your DatabaseSeeder.php file.

And you need to run in your console:

composer dump-autoload

to generate new class map and then run:

php artisan db:seed

I've just tested it. It is working without a problem in Laravel 5

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

Use this command:

truncate -s 0 /home/SYSTEM_NAME/.ssh/known_hosts

You can paste it like this:

= "2010-12-20" - 180

And don't forget to format the cell as a Date [CTRL]+[F1] / Number Tab

To clear some confusion:

This is done in 2 steps: Setting the button background attribute to android:attr/selectableItemBackground creates you a button with feedback but no background.

android:background="?android:attr/selectableItemBackground"

The line to divide the borderless button from the rest of you layout is done by a view with the background android:attr/dividerVertical

android:background="?android:attr/dividerVertical"

For a better understanding here is a layout for a OK / Cancel borderless button combination at the bottom of your screen (like in the right picture above).

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="48dp"

            android:layout_alignParentLeft="true"
            android:layout_alignParentTop="true"
            android:layout_toLeftOf="@id/ViewColorPickerHelper"
            android:background="?android:attr/selectableItemBackground"
            android:text="@android:string/cancel" 
            android:layout_alignParentBottom="true"/>
        <Button

            android:text="@android:string/ok" 
            android:layout_alignParentBottom="true" 
            android:layout_toRightOf="@id/ViewColorPickerHelper"/>
    </RelativeLayout>

Something like this should work: /([^/]*)$

What language are you using? End-of-string regex signifiers can vary in different languages.

var gandalf = {
  "real name": "Gandalf",
  "age (est)": 11000,
  "race": "Maia",
  "haveRetirementPlan": true,
  "aliases": [
    "Greyhame",
    "Stormcrow",
    "Mithrandir",
    "Gandalf the Grey",
    "Gandalf the White"
  ]
};
//to console log object, we cannot use console.log("Object gandalf: " + gandalf);
console.log("Object gandalf: ");
//this will show object gandalf ONLY in Google Chrome NOT in IE
console.log(gandalf);
//this will show object gandalf IN ALL BROWSERS!
console.log(JSON.stringify(gandalf));
//this will show object gandalf IN ALL BROWSERS! with beautiful indent
console.log(JSON.stringify(gandalf, null, 4));

to set RichTextBox text:

richTextBox1.Document.Blocks.Clear();
richTextBox1.Document.Blocks.Add(new Paragraph(new Run("Text")));

to get RichTextBox text:

string richText = new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text;

Using this answer requires that you create and maintain a file that contains the package names you want installed on your system. If you don't have one already, use the following command and delete the package names what you don't want to keep installed.

brew leaves > brew_packages

Then you can remove all installed, but unwanted packages and any unnecessary dependencies by running the following command

brew_clean brew_packages

brew_clean is available here: https://gist.github.com/cskeeters/10ff1295bca93808213d

This script gets all of the packages you specified in brew_packages and all of their dependancies and compares them against the output of brew list and finally removes the unwanted packages after verifying this list with the user.

At this point if you want to remove package a, you simply remove it from the brew_packages file then re-run brew_clean brew_packages. It will remove b, but not c.

along with these two variants, there is also jade.renderFile which generates html that need not be passed to the client.

usage-

var jade = require('jade');

exports.getJson = getJson;

function getJson(req, res) {
    var html = jade.renderFile('views/test.jade', {some:'json'});
    res.send({message: 'i sent json'});
}

getJson() is available as a route in app.js.

A clustered index actually describes the order in which records are physically stored on the disk, hence the reason you can only have one.

A Non-Clustered Index defines a logical order that does not match the physical order on disk.

Or use group_by & summarise_at from the dplyr package:

library(dplyr)

d %>%
  group_by(Name) %>%
  summarise_at(vars(-Month), funs(mean(., na.rm=TRUE)))

# A tibble: 3 x 3
  Name  Rate1 Rate2
  <fct> <dbl> <dbl>
1 Aira   16.3  47.0
2 Ben    31.3  50.3
3 Cat    44.7  54.0

See ?summarise_at for the many ways to specify the variables to act on. Here, vars(-Month) says all variables except Month.

Yes, it is. Declare parameter as so:

@Sort varchar(50) = NULL

Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).

I don't think using one printf statement to print string literals as seen above is a good programming practice; rather, one can use the piece of code below:

printf("name: %s\t",sp->name);
printf("args: %s\t",sp->args);
printf("value: %s\t",sp->value);
printf("arraysize: %s\t",sp->name); 

If you really don't like the Terminal here is the GUI way to do dkamins is telling you :

1) Go to your user home directory (ludo would be mine) and from the File menu choose Get Info cmdI in the inspector :

2) By alt/option clicking on the [+] sign add the _www group and set it's permission to read-only :

• Thus consider (good practice) not storing personnal information at the root of your user home folder (& hard disk) !
• You may skip this step if the **everyone** group has **read-only** permission but since AirDrop the **/Public/Drop Box** folder is mostly useless...

3) Show the Get Info inspector of your user Sites folder and reproduce step 2 then from the gear action sub-menu choose Apply to enclosed Items... :

Voilà 3 steps and the GUI only way...

'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500

You can do it with simple if statement

To check for float

if type(a)==type(1.1)

To check for integer type

if type(a)==type(1)

Assuming you've created the variable path for maven as follows:

Under System path, click new then edit as follows:

Variable name: MAVEN_HOME

Variable value: C:\Program Files\apache-maven-3.5.3\bin

Then continue with these instructions:

Under System Path, update variable path by clicking on edit and add:

C:\Program Files\apache-maven-3.5.3\bin;

immediately after:

C:\Program Files\Java\jdk\1.8.0_161\bin;

remember to add semi-colon ; after \bin as included above and then run your cmd prompt and type:

mvn -v 

The code seems working to me. I think the same with @Iothar.

Check to see if you include the required headers, to compile. If it is compiled, check to see if there is such a file, and everything, names etc, matches, and also check to see that you have a right to read the file.

To make a cross check, check if you can open it with fopen..

FILE *f = fopen("C:/Demo.txt", "r");
if (f)
  printf("fopen success\n");

memory mapping is not only used to map files into memory but is also a tool to request RAM from kernel. These are those inode 0 entries - your stack, heap, bss segments and more

You can do it easily with regexp in one line of code

const str = 'Hello RegExp!';_x000D_
const index = 6;_x000D_
const insert = 'Lovely ';_x000D_
    _x000D_
//'Hello RegExp!'.replace(/^(.{6})(.)/, `$1Lovely $2`);_x000D_
const res = str.replace(new RegExp(`^(.{${index}})(.)`), `$1${insert}$2`);_x000D_
    _x000D_
console.log(res);

"Hello Lovely RegExp!"

If you want to start at the "application root" as you describe right click on the top level Default.aspx page and choose set as start page. Hit F5 and you're done.

If you want to start at a different controller action see Mark's answer.

Its quite easy on computer a you don't need to do anything just make sure both system are on same network if its not internet access(for this you need static ip). Okay now on computer b go to start menu find configuration under oracle folder click Net Configuration Assistant under that folder when window pop up click Local net configuration option it must be third option.

Now click add and click next in next screen it will ask service name here you need to add oracle global database name of computer A(Normally I use oracle86 for my installation) now click next next screen choose protocol normally its tcp click next in host name enter computer A's name you can found that in my computer properties. Click next don't change port untill you have changed that in Computer A click next and choose test connection now here you can check your connection working or not if the error is username and password not correct then click login credential button and fill correct username and password. If its saying unable to reach computer ot target not found than you must add exception in firewall for 1521 port or just disable firewall on computer A.

Position:fixed gives an absolute position regarding the BROWSER window. so of course it goes there.

While position:absolute refers to the parent element, so if you place your <div> button inside the <div> of the container, it should position where you meant it to be. Something like

Prepared statements / parameterized queries are generally sufficient to prevent 1st order injection on that statement^*. If you use un-checked dynamic sql anywhere else in your application you are still vulnerable to 2nd order injection.

2nd order injection means data has been cycled through the database once before being included in a query, and is much harder to pull off. AFAIK, you almost never see real engineered 2nd order attacks, as it is usually easier for attackers to social-engineer their way in, but you sometimes have 2nd order bugs crop up because of extra benign ' characters or similar.

You can accomplish a 2nd order injection attack when you can cause a value to be stored in a database that is later used as a literal in a query. As an example, let's say you enter the following information as your new username when creating an account on a web site (assuming MySQL DB for this question):

' + (SELECT UserName + '_' + Password FROM Users LIMIT 1) + '

If there are no other restrictions on the username, a prepared statement would still make sure that the above embedded query doesn't execute at the time of insert, and store the value correctly in the database. However, imagine that later the application retrieves your username from the database, and uses string concatenation to include that value a new query. You might get to see someone else's password. Since the first few names in users table tend to be admins, you may have also just given away the farm. (Also note: this is one more reason not to store passwords in plain text!)

We see, then, that prepared statements are enough for a single query, but by themselves they are not sufficient to protect against sql injection attacks throughout an entire application, because they lack a mechanism to enforce all access to a database within an application uses safe code. However, used as part of good application design — which may include practices such as code review or static analysis, or use of an ORM, data layer, or service layer that limits dynamic sql — prepared statements are the primary tool for solving the Sql Injection problem. If you follow good application design principles, such that your data access is separated from the rest of your program, it becomes easy to enforce or audit that every query correctly uses parameterization. In this case, sql injection (both first and second order) is completely prevented.

_{^*It turns out that MySql/PHP are (okay, were) just dumb about handling parameters when wide characters are involved, and there is still a rare case outlined in the other highly-voted answer here that can allow injection to slip through a parameterized query.}

Example of uppercasedFirstCharacter convenience property in Swift3 and Swift4.

Property uppercasedFirstCharacterNew demonstrates how to use String slicing subscript in Swift4.

extension String {

   public var uppercasedFirstCharacterOld: String {
      if characters.count > 0 {
         let splitIndex = index(after: startIndex)
         let firstCharacter = substring(to: splitIndex).uppercased()
         let sentence = substring(from: splitIndex)
         return firstCharacter + sentence
      } else {
         return self
      }
   }

   public var uppercasedFirstCharacterNew: String {
      if characters.count > 0 {
         let splitIndex = index(after: startIndex)
         let firstCharacter = self[..<splitIndex].uppercased()
         let sentence = self[splitIndex...]
         return firstCharacter + sentence
      } else {
         return self
      }
   }
}

let lorem = "lorem".uppercasedFirstCharacterOld
print(lorem) // Prints "Lorem"

let ipsum = "ipsum".uppercasedFirstCharacterNew
print(ipsum) // Prints "Ipsum"

Try to update the below two parameters as they must be having default values.

innodb_lock_wait_timeout = 50

innodb_rollback_on_timeout = ON

For checking parameter value you can use the below SQL.

SHOW GLOBAL VARIABLES LIKE 'innodb_rollback_on_timeout';

The mandelbrot set is generated by repeatedly evaluating a function until it overflows (some defined limit), then checking how long it took you to overflow.

MAX_COUNT = 64 // if we haven't escaped to infinity after 64 iterations, 
               // then we're inside the mandelbrot set!!!

foreach (x-pixel)
  foreach (y-pixel)
    calculate x,y as mathematical coordinates from your pixel coordinates
    value = (x, y)
    count = 0
    while value.absolutevalue < 1 billion and count < MAX_COUNT
        value = value * value + (x, y)
        count = count + 1

    // the following should really be one statement, but I split it for clarity
    if count == MAX_COUNT 
        pixel_at (x-pixel, y-pixel) = BLACK
    else 
        pixel_at (x-pixel, y-pixel) = colors[count] // some color map. 

Notes:

value is a complex number. a complex number (a+bi) is squared to give (aa-b*b+2*abi). You'll have to use a complex type, or include that calculation in your loop.

There's a function empty() ready for you in std::string:

std::string a;
if(a.empty())
{
    //do stuff. You will enter this block if the string is declared like this
}

or

std::string a;
if(!a.empty())
{
    //You will not enter this block now
}
a = "42";
if(!a.empty())
{
    //And now you will enter this block.
}

The problem may lie in you don't have enabled openssl extention in your php.ini file

go to your php.ini file end remove ; in line where extension=openssl is

Of course in question code there is a part of code responsible for checking whether extension is loaded or not but maybe some uncautious forget about it

You might want to take a look at a similar question posted on Stack Overflow. It uses the .apply() method to accomplish this.

The reason why your image is resizing which is because it is fluid. You have two ways to do it:

1. Either give a fixed dimension to your image using CSS like:

   .carousel-inner > .item > img {
     width:640px;
     height:360px;
   }

2. A second way to can do this:

   .carousel {
     width:640px;
     height:360px;
   }

The "table-column" display type means it acts like the <col> tag in HTML - i.e. an invisible element whose width* governs the width of the corresponding physical column of the enclosing table.

See the W3C standard for more information about the CSS table model.

* And a few other properties like borders, backgrounds.

I would like to add yourkit java and .net profiler, I love it for Java, haven't tried .NET version though.

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

Method for comparing 2 dates (util.date or sql.date)

 public static boolean isSameDay(Date a, Date b) {
    Calendar calA = new GregorianCalendar();
    calA.setTime(a);

    Calendar calB = new GregorianCalendar();
    calB.setTime(b);

    final int yearA = calA.get(Calendar.YEAR);
    final int monthA = calA.get(Calendar.MONTH);
    final int dayA = calA.get(Calendar.DAY_OF_YEAR);

    final int yearB = calB.get(Calendar.YEAR);
    final int monthB = calB.get(Calendar.MONTH);
    final int dayB = calB.get(Calendar.DAY_OF_YEAR);

    return yearA == yearB && monthA == monthB && dayA == dayB;
}

This worked for me, It might just work for you if you are using Ubuntu 16 or 18 (14 may also work). Easy to give a try:

Go to Ubuntu Software, type in Docker. Uninstall docker (108 mb) if it is preinstalled there. Install docker Now run the commands and see if the same error comes

The error:

After doing the above steps.

As you can see, it worked:)

Better use PHP_EOL ("End Of Line") instead. It's cross-platform.

E.g.:

$unit1 = 'paragrahp1';
$unit2 = 'paragrahp2';
echo '<p>' . $unit1 . '</p>' . PHP_EOL;
echo '<p>' . $unit2 . '</p>';

The top answer worked fine for me, except that I needed to whitelist more than one domain.

Also, top answer suffers from the fact that OPTIONS request isn't handled by middleware and you don't get it automatically.

I store whitelisted domains as allowed_origins in Express configuration and put the correct domain according to origin header since Access-Control-Allow-Origin doesn't allow specifying more than one domain.

Here's what I ended up with:

var _ = require('underscore');

function allowCrossDomain(req, res, next) {
  res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS');

  var origin = req.headers.origin;
  if (_.contains(app.get('allowed_origins'), origin)) {
    res.setHeader('Access-Control-Allow-Origin', origin);
  }

  if (req.method === 'OPTIONS') {
    res.send(200);
  } else {
    next();
  }
}

app.configure(function () {
  app.use(express.logger());
  app.use(express.bodyParser());
  app.use(allowCrossDomain);
});

One of the reason may be if any one of table column have an underscore(_) in its name . That is considered as invalid characters by the JDBC . Rename the column by a ALTER Command and change in your code SQL , that will fix .

try

el.css('margin-left',mrg+'px');

Here's a performance test for the solutions posted here. https://github.com/tedgonzalez/MaxElementInCollectionPerformance

This is the fastest for Swift 5

array.max()

Quoted from https://developer.mozilla.org/en/DOM/element.click

The click method is intended to be used with INPUT elements of type button, checkbox, radio, reset or submit. Gecko does not implement the click method on other elements that might be expected to respond to mouse–clicks such as links (A elements), nor will it necessarily fire the click event of other elements.

Non–Gecko DOMs may behave differently.

Unfortunately it sounds like you have already discovered the best solution to your problem.

As a side note, I agree that your solution seems less than ideal, but if you encapsulate the functionality inside a method (much like JQuery would do) it is not so bad.

I had the same problem, and I resolve doing this npm update. But I receive the message about permission, so I run:

sudo chwon -R myuser /home/myUserFolder/.config

This set permissions for my user run npm comands like administrator. Then I run this again:

npm update 

and this:

npm install gulp-sass

Then my problem with this was solved.

This question was asked before Java 7 release but now, there is another possible way using Java 7 (and above) API:

double random = ThreadLocalRandom.current().nextDouble(min, max);

nextDouble will return a pseudorandom double value between the minimum (inclusive) and the maximum (exclusive). The bounds are not necessarily int, and can be double.

Warning about using TODAY (or any calcs in a column).

If you set up a filter and have JUST [Today] it it you should be fine.

But the moment you do something like [Today]-1 ... the view will no longer show up when trying to pick it for alerts.

Another microsoft wonder.

from learnyounode:

var http = require('http')  

http.get(options, function (response) {  
  response.setEncoding('utf8')  
  response.on('data', console.log)  
  response.on('error', console.error)  
})

'options' is the host/path variable

I think (I'm not certain) that foreign key constraints won't do precisely what you want given your table design. Perhaps the best thing to do is to define a stored procedure that will delete a category the way you want, and then call that procedure whenever you want to delete a category.

CREATE PROCEDURE `DeleteCategory` (IN category_ID INT)
LANGUAGE SQL
NOT DETERMINISTIC
MODIFIES SQL DATA
SQL SECURITY DEFINER
BEGIN

DELETE FROM
    `products`
WHERE
    `id` IN (
        SELECT `products_id`
        FROM `categories_products`
        WHERE `categories_id` = category_ID
    )
;

DELETE FROM `categories`
WHERE `id` = category_ID;

END

You also need to add the following foreign key constraints to the linking table:

ALTER TABLE `categories_products` ADD
    CONSTRAINT `Constr_categoriesproducts_categories_fk`
    FOREIGN KEY `categories_fk` (`categories_id`) REFERENCES `categories` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE,
    CONSTRAINT `Constr_categoriesproducts_products_fk`
    FOREIGN KEY `products_fk` (`products_id`) REFERENCES `products` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE

The CONSTRAINT clause can, of course, also appear in the CREATE TABLE statement.

Having created these schema objects, you can delete a category and get the behaviour you want by issuing CALL DeleteCategory(category_ID) (where category_ID is the category to be deleted), and it will behave how you want. But don't issue a normal DELETE FROM query, unless you want more standard behaviour (i.e. delete from the linking table only, and leave the products table alone).

You can do the following. Add your ggplot code after the first line of code and end with dev.off().

tiff("test.tiff", units="in", width=5, height=5, res=300)
# insert ggplot code
dev.off()

res=300 specifies that you need a figure with a resolution of 300 dpi. The figure file named 'test.tiff' is saved in your working directory.

Change width and height in the code above depending on the desired output.

Note that this also works for other R plots including plot, image, and pheatmap.

Other file formats

In addition to TIFF, you can easily use other image file formats including JPEG, BMP, and PNG. Some of these formats require less memory for saving.

I had trouble with a crashing program *cough PHP cough* Upon crash the shell it was ran in reports the crash reason, Segmentation fault (core dumped)

To avoid this output not getting logged, the command can be run in a subshell that will capture and direct these kind of output:

sh -c 'your_command' > your_stdout.log 2> your_stderr.err
# or
sh -c 'your_command' > your_stdout.log 2>&1

Although using File.separator to reference a file name is overkill (for those who imagine far off lands, I imagine their JVM implementation would replace a / with a : just like the windows jvm replaces it with a \).

However, sometimes you are getting the file reference, not creating it, and you need to parse it, and to be able to do that, you need to know the separator on the platform. File.separator helps you do that.

Try pgrep. Its output format is much simpler and therefore easier to parse.

Easier when your number after the decimal (0.xxx) is short. Then all you need to do is multiply that number with the number after the division.

Ex: 32 % 12 = 8

You do 32/12=2.666666667 Then you throw the 2 away, and focus on the 0.666666667 0.666666667*12=8 <-- That's your answer.

(again, only easy when the number after the decimal is short)

Here are the complete steps after reading many answers here

How to set up Multiple SSH Keys settings for different github account

You might want to start checking your currently saved keys

$ ssh-add -l

If you decide to delete all cached keys before (optional, carefull about this)

$ ssh-add -D

Then you can create a ssh pub/priv key linked to each email/account that you wish/need to use

$ cd ~/.ssh
$ ssh-keygen -t rsa -C "[email protected]" <-- save it as "id_rsa_work"
$ ssh-keygen -t rsa -C "[email protected]" <-- save it as "id_rsa_pers"

After performing this commands you will have the following files created

~/.ssh/id_rsa_work      
~/.ssh/id_rsa_work.pub

~/.ssh/id_rsa_pers
~/.ssh/id_rsa_pers.pub 

Make sure authentication agent is running

$ eval `ssh-agent -s`

Add the generated keys as following (from the ~/.ssh folder)

$ ssh-add id_rsa_work
$ ssh-add id_rsa_pers

Now you can check your saved keys again

$ ssh-add -l

Now you need to add the generated public keys to your github/bickbuket server Acces Keys

Clone each of the repos to different folders

Go to the folder where the user work will work and execute this

$ git config user.name "Working Hard"
$ git config user.email "[email protected]" 

Just to see what this does check the contents of the ".git/config"

Go to the folder where the user pers will work and execute this

$ git config user.name "Personal Account"
$ git config user.email "[email protected]" 

Just to see what this does check the contents of the ".git/config"

After all this you will be able to commit your personal and work code by just switching between those two folders

In case you are using Git Bash and need to generate ssh keys under Windows follow this steps:

A threadpool is at core a set of threads all bound to a function working as an event loop. These threads will endlessly wait for a task to be executed, or their own termination.

The threadpool job is to provide an interface to submit jobs, define (and perhaps modify) the policy of running these jobs (scheduling rules, thread instantiation, size of the pool), and monitor the status of the threads and related resources.

So for a versatile pool, one must start by defining what a task is, how it is launched, interrupted, what is the result (see the notion of promise and future for that question), what sort of events the threads will have to respond to, how they will handle them, how these events shall be discriminated from the ones handled by the tasks. This can become quite complicated as you can see, and impose restrictions on how the threads will work, as the solution becomes more and more involved.

The current tooling for handling events is fairly barebones(*): primitives like mutexes, condition variables, and a few abstractions on top of that (locks, barriers). But in some cases, these abstrations may turn out to be unfit (see this related question), and one must revert to using the primitives.

Other problems have to be managed too:

• signal
• i/o
• hardware (processor affinity, heterogenous setup)

How would these play out in your setting?

This answer to a similar question points to an existing implementation meant for boost and the stl.

I offered a very crude implementation of a threadpool for another question, which doesn't address many problems outlined above. You might want to build up on it. You might also want to have a look of existing frameworks in other languages, to find inspiration.

_{(*) I don't see that as a problem, quite to the contrary. I think it's the very spirit of C++ inherited from C.}

This is totally OK.

1. The first group (m.group(0)) always captures the whole area that is covered by your regular expression. In this case, it's the whole string.
2. Regular expressions are greedy by default, meaning that the first group captures as much as possible without violating the regex. The (.*)(\\d+) (the first part of your regex) covers the ...QT300 int the first group and the 0 in the second.
3. You can quickly fix this by making the first group non-greedy: change (.*) to (.*?).

For more info on greedy vs. lazy, check this site.

Information for obsoleted prerelease software:

According to this it's just a install and go for Visual Studio 2013:

In fact, installing the C# 6.0 compiler from this release involves little more than installing a Visual Studio 2013 extension, which in turn updates the MSBuild target files.

So just get the files from https://github.com/dotnet/roslyn and you are ready to go.

You do have to know it is an outdated version of the specs implemented there, since they no longer update the package for Visual Studio 2013:

You can also try April's End User Preview, which installs on top of Visual Studio 2013. (note: this VS 2013 preview is quite out of date, and is no longer updated)

So if you do want to use the latest version, you have to download the Visual Studio 2015.

I think you can force change the keyboard type by implementing UITextInputTraits protocol, optional var keyboardType

//class ViewController: UIViewController, UITextInputTraits {

@IBOutlet weak var textFieldKeyboardType: UITextField!{
    didSet{
        textFieldKeyboardType.keyboardType = UIKeyboardType.NumberPad
    }
}
var keyboardType: UIKeyboardType { 
    get{ 
        return textFieldKeyboardType.keyboardType
    } 
    set{ 
        if newValue != UIKeyboardType.NumberPad{
            self.keyboardType = UIKeyboardType.NumberPad
        }
    } 
}

In order to include a global library, eg jquery.js file in the scripts array from angular-cli.json (angular.json when using angular 6+):

"scripts": [
  "../node_modules/jquery/dist/jquery.js"
]

After this, restart ng serve if it is already started.

Spring MVC and Spring Boot are exist for the different purpose. So, it is not wise to compare each other as the contenders.

What is Spring Boot?

Spring Boot is a framework for packaging the spring application with sensible defaults. What does this mean?. You are developing a web application using Spring MVC, Spring Data, Hibernate and Tomcat. How do you package and deploy this application to your web server. As of now, we have to manually write the configurations, XML files, etc. for deploying to web server.

Spring Boot does that for you with Zero XML configuration in your project. Believe me, you don't need deployment descriptor, web server, etc. Spring Boot is magical framework that bundles all the dependencies for you. Finally your web application will be a standalone JAR file with embeded servers.

If you are still confused how this works, please read about microservice framework development using spring boot.

What is Spring MVC?

It is a traditional web application framework that helps you to build web applications. It is similar to Struts framework.

A Spring MVC is a Java framework which is used to build web applications. It follows the Model-View-Controller design pattern. It implements all the basic features of a core spring framework like Inversion of Control, Dependency Injection.

A Spring MVC provides an elegant solution to use MVC in spring framework by the help of DispatcherServlet. Here, DispatcherServlet is a class that receives the incoming request and maps it to the right resource such as controllers, models, and views.

I hope this helps you to understand the difference.

If you want to split you dataframe into two different ones, do two selects on it with the different columns you want.

 val sourceDf = spark.read.csv(...)
 val df1 = sourceDF.select("first column", "second column", "third column")
 val df2 = sourceDF.select("first column", "second column", "third column")

Note that this of course means that the sourceDf would be evaluated twice, so if it can fit into distributed memory and you use most of the columns across both dataframes it might be a good idea to cache it. It it has many extra columns that you don't need, then you can do a select on it first to select on the columns you will need so it would store all that extra data in memory.

MyViewClass *myViewObject = [[[NSBundle mainBundle] loadNibNamed:@"MyViewClassNib" owner:self options:nil] objectAtIndex:0]

I'm using this to initialise the reusable custom views I have.

Note that you can use "firstObject" at the end there, it's a little cleaner. "firstObject" is a handy method for NSArray and NSMutableArray.

Here's a typical example, of loading a xib to use as a table header. In your file YourClass.m

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    return [[NSBundle mainBundle] loadNibNamed:@"TopArea" owner:self options:nil].firstObject;
}

Normally, in the TopArea.xib, you would click on File Owner and set the file owner to YourClass. Then actually in YourClass.h you would have IBOutlet properties. In TopArea.xib, you can drag controls to those outlets.

Don't forget that in TopArea.xib, you may have to click on the View itself and drag that to some outlet, so you have control of it, if necessary. (A very worthwhile tip is that when you are doing this for table cell rows, you absolutely have to do that - you have to connect the view itself to the relevant property in your code.)

Try

• brew cask install android-platform-tools
• adb reverse tcp:9090 tcp:9090
• run the app

I had the same problem but it only occurred on the published website on Godaddy. It was no problem in my local host.

The error came from an aspx.cs (code behind file) where I tried to assign a value to a label. It appeared that from within the code behind, that the label Text appears to be null. So all I did with change all my Label Text properties in the ASPX file from Text="" to Text=" ".

The problem disappeared. I don’t know why the error happens from the hosted version but not on my localhost and don’t have time to figure out why. But it works fine now.

The folder containing your Anaconda installation contains a subfolder called conda-meta with json files for all installed packages, including one for Anaconda itself. Look for anaconda-<version>-<build>.json.

My file is called anaconda-5.0.1-py27hdb50712_1.json, and at the bottom is more info about the version:

"installed_by": "Anaconda2-5.0.1-Windows-x86_64.exe", 
"link": { "source": "C:\\ProgramData\\Anaconda2\\pkgs\\anaconda-5.0.1-py27hdb50712_1" }, 
"name": "anaconda", 
"platform": "win", 
"subdir": "win-64", 
"url": "https://repo.continuum.io/pkgs/main/win-64/anaconda-5.0.1-py27hdb50712_1.tar.bz2", 
"version": "5.0.1"

(Slightly edited for brevity.)

The output from conda -V is the conda version.

I had a similar problem. I ended up nuking it from orbit, and lost my SVN history in the process. But at least I made that damn error go away.

This is probably a sub-optimal sequence of commands to execute, but it should fairly closely follow the sequence of commands that I actually did to get things to work:

cp -rp target ~/other/location/target-20111108
svn rm target --force
cp -rp ~/other/location/target-20111108 target-other-name
cd target-other-name
find . -name .svn -print | xargs rm -rf
cd ..
svn add target-other-name
svn ci -m "Re-re-re-re-re-re-re-re-re-re import target"
svn mv target-other-name target
svn ci -m "Re-re-re-re-re-re-re-re-re-re import target"

Not so graceful, but the very much simple in implementation solution - using global variable.

In the "first" file:

window.myApp = angular.module("myApp", [])
....

in the "second" , "third", etc:

myApp.controller('MyController', function($scope) {
    .... 
    }); 

You should create a method within your fragment that accepts the type of object you wish to pass into it. In this case i named it "setObject" (creative huh? :) ) That method can then perform whatever action you need with that object.

MyFragment fragment;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

        if (getSupportFragmentManager().findFragmentById(android.R.id.content) == null) {
            fragment = new MyFragment();
            getSupportFragmentManager().beginTransaction().add(android.R.id.content, detailsFragment)
                    .commit();
        } else {
           fragment = (MyFragment) getSupportFragmentManager().findFragmentById(
                    android.R.id.content);
        }


        fragment.setObject(yourObject); //create a method like this in your class "MyFragment"
}

Note that i'm using the support library and calls to getSupportFragmentManager() might be just getFragmentManager() for you depending on what you're working with

A great resource is iosfonts.com, which says that the name for that font is HelveticaNeue-UltraLight. So you'd use this code:

label.font = UIFont(name: "HelveticaNeue-UltraLight", size: 30)

If the system can't find the font, it defaults to a 'normal' font - I think it's something like 11-point Helvetica. This can be quite confusing, always check your font names.

From all the answers above, Björn's answer seems to be the most elegant and short. I personally used this approach many times. MAX or MIN function will do the job equally well. Complete PL/SQL follows, just the where clause should be specified.

declare v_column my_table.column%TYPE;
begin
    select MIN(column) into v_column from my_table where ...;
    DBMS_OUTPUT.PUT_LINE('v_column=' || v_column);
end;

This is also easy to read:

FilePath=(
    "/tmp/path1/"    #FilePath[0]
    "/tmp/path2/"    #FilePath[1]
)

#Loop
for Path in "${FilePath[@]}"
do
    echo "$Path"
done

try this

$("input[name=search-mini]").on("search", function() {
 //do something for search
});

if you want to use report in asp.net then use .rdl if you want to use /view in report builder / report server then use .rdlc just by converting format manually it works

From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning

the following

Excessive GC Time and OutOfMemoryError

The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.

The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).

in conjunction with a passage further down

One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,

java -Dsun.rmi.dgc.client.gcInterval=3600000

-Dsun.rmi.dgc.server.gcInterval=3600000 specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.

Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.

Of course, other interpretations are possible.

For what's worth, this command did it for me (Python3.3) :

[System.Environment]::SetEnvironmentVariable("PATH", $Env:Path + ";C:\Python33", "Machine")

I just had to restart the Powershell after that.

Here's some code that'll substitute for the blink tag

<p id="blink">This text will blink!</p>
<script>
var blacktime = 1000;
var whitetime = 1000;
//These can be as long as you desire in milliseconds
setTimeout(whiteFunc,blacktime);
function whiteFunc(){
    document.getElementById("blink").style.color = "white";
    setTimeout(blackFunc,whitetime);
}
function blackFunc(){
    document.getElementById("blink").style.color = "black";
    setTimeout(whiteFunc,blacktime);
}
</script>

In my case it helped to try and connect to the port - if service is already present, it would respond.

    try {
        log.debug("{}: Checking if port open by trying to connect as a client", portNumber);
        Socket sock = new Socket("localhost", portNumber);          
        sock.close();
        log.debug("{}: Someone responding on port - seems not open", portNumber);
        return false;
    } catch (Exception e) {         
        if (e.getMessage().contains("refused")) {
            return true;
    }
        log.error("Troubles checking if port is open", e);
        throw new RuntimeException(e);              
    }

I had the same issue with a .tgz file .

It was just about the location of the file. Ensure the file is in the same directory of the Dockerfile.

Also ensure the .dockerignore file directory doesn't exclude the file regex pattern.

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.

You can use the file_get_contents function to access remote files. See http://php.net/manual/en/function.file-get-contents.php for details.

The short answer is:

snprintf( str, size, "%d", x );

The longer is: first you need to find out sufficient size. snprintf tells you length if you call it with NULL, 0 as first parameters:

snprintf( NULL, 0, "%d", x );

Allocate one character more for null-terminator.

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

int x = -42;
int length = snprintf( NULL, 0, "%d", x );
char* str = malloc( length + 1 );
snprintf( str, length + 1, "%d", x );
...
free(str);

If works for every format string, so you can convert float or double to string by using "%g", you can convert int to hex using "%x", and so on.

This link should get you started. Long story short, a div that has been styled to look like a scrollbar is used to catch click-and-drag events. Wired up to these events are methods that scroll the contents of another div which is set to an arbitrary height and typically has a css rule of overflow:scroll (there are variants on the css rules but you get the idea).

I'm all about the learning experience -- but after you've learned how it works, I recommend using a library (of which there are many) to do it. It's one of those "don't reinvent" things...

As of python 3.2, using only standard library functions:

u_tm = datetime.datetime.utcfromtimestamp(0)
l_tm = datetime.datetime.fromtimestamp(0)
l_tz = datetime.timezone(l_tm - u_tm)

t = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, tzinfo=l_tz)
str(t)
'2009-07-10 18:44:59.193982-07:00'

Just need to use l_tm - u_tm or u_tm - l_tm depending whether you want to show as + or - hours from UTC. I am in MST, which is where the -07 comes from. Smarter code should be able to figure out which way to subtract.

And only need to calculate the local timezone once. That is not going to change. At least until you switch from/to Daylight time.

This will also change it into an array:

<?php
    print_r((array) json_decode($object));
?>

var test = parseInt($("#testid").val(), 10);

You have to tell it you want the value of the input you are targeting.

And also, always provide the second argument (radix) to parseInt. It tries to be too clever and autodetect it if not provided and can lead to unexpected results.

Providing 10 assumes you are wanting a base 10 number.

The best way is to create a variable of type Worksheet, assign the worksheet and use it every time the VBA would implicitly use the ActiveSheet.

This will help you avoid bugs that will eventually show up when your program grows in size.

For example something like Range("A1:C10").Sort Key1:=Range("A2") is good when the macro works only on one sheet. But you will eventually expand your macro to work with several sheets, find out that this doesn't work, adjust it to ShTest1.Range("A1:C10").Sort Key1:=Range("A2")... and find out that it still doesn't work.

Here is the correct way:

Dim ShTest1 As Worksheet
Set ShTest1 = Sheets("Test1")
ShTest1.Range("A1:C10").Sort Key1:=ShTest1.Range("A2")

simple google search came up with this. Doubt anyone can explain this any simpler. But I guess after an edit, I can try to bring forward the concepts so that you can answer your own question.

Hint :

Study for exam, hard, you must. Predict you, grade get high, I do :D

Explanation :

It's all about the way operations are associated with operands. each notation type has its own rules. You just need to break down and remember these rules. If I told you I wrote (2*2)/3 as [* /] (2,2,3) all you need to do is learn how to turn the latter notation in the former notation.

My custom notation says that take the first two operands and multiple them, then the resulting operand should be divided by the third. Get it ? They are trying to teach you three things.

1. To become comfortable with different notations. The example I gave is what you will find in assembly languages. operands (which you act on) and operations (what you want to do to the operands).
2. Precedence rules in computing do not necessarily need to follow those found in mathematics.
3. Evaluation: How a machine perceives programs, and how it might order them at run-time.

It is strange, that no one yet has suggested the most robust way of closing a feature branches... You can just combine merge commit with --close-branch flag (i.e. commit modified files and close the branch simultaneously):

hg up feature-x
hg merge default
hg ci -m "Merge feature-x and close branch" --close-branch
hg branch default -f

So, that is all. No one extra head on revgraph. No extra commit.

From the documentation , the function mysqli_real_escape_string() has two parameters.

string mysqli_real_escape_string ( mysqli $link , string $escapestr ).

The first one is a link for a mysqli instance (database connection object), the second one is the string to escape. So your code should be like :

$username = mysqli_real_escape_string($yourconnectionobject,$_POST['username']);

First of all, what you have is a fully compiled program, not an object file, so drop the .o extension. Now, pay attention to what the error message says, it tells you exactly how to fix your problem: "No symbol table is loaded. Use the "file" command."

(gdb) exec-file test

Or just pass the program on the command line.

I think you should mention dataType: 'json' in ajax config and to access that value:

data[0].name

The following expression worked for me:

SELECT CONVERT(VARCHAR(1000), varbinary_value, 2);

Here are more details on the choice of style (the third parameter).

Most efficient code to find length of a number.. counts zeros as well, note "n" is the number to be given.

while(n!=0)

Depth-first Search

Depth-first searches are often used in simulations of games (and game-like situations in the real world). In a typical game you can choose one of several possible actions. Each choice leads to further choices, each of which leads to further choices, and so on into an ever-expanding tree-shaped graph of possibilities.

For example in games like Chess, tic-tac-toe when you are deciding what move to make, you can mentally imagine a move, then your opponent’s possible responses, then your responses, and so on. You can decide what to do by seeing which move leads to the best outcome.

Only some paths in a game tree lead to your win. Some lead to a win by your opponent, when you reach such an ending, you must back up, or backtrack, to a previous node and try a different path. In this way you explore the tree until you find a path with a successful conclusion. Then you make the first move along this path.

Breadth-first search

The breadth-first search has an interesting property: It first finds all the vertices that are one edge away from the starting point, then all the vertices that are two edges away, and so on. This is useful if you’re trying to find the shortest path from the starting vertex to a given vertex. You start a BFS, and when you find the specified vertex, you know the path you’ve traced so far is the shortest path to the node. If there were a shorter path, the BFS would have found it already.

Breadth-first search can be used for finding the neighbour nodes in peer to peer networks like BitTorrent, GPS systems to find nearby locations, social networking sites to find people in the specified distance and things like that.

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

This is the best option to cast/convert list of generic object to list of string.

object valueList;
List<string> list = ((IList)valueList).Cast<object>().Select(o => o.ToString()).ToList();

def attributeSelection():
balance = 25
print("Your SP balance is currently 25.")
strength = input("How much SP do you want to put into strength?")
balanceAfterStrength = balance - int(strength)
if balanceAfterStrength == 0:
    print("Your SP balance is now 0.")
    attributeConfirmation()
elif strength < 0:
    print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")
    attributeSelection()
elif strength > balance:
    print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")
    attributeSelection()
elif balanceAfterStrength > 0 and balanceAfterStrength < 26:
    print("Ok. You're balance is now at " + str(balanceAfterStrength) + " skill points.")
else:
    print("That is an invalid input. Restarting attribute selection.")
    attributeSelection()

The option to save the .orig file can be disabled by configuring KDiff3

1. List all jar files from the Eclipse Navigator mode
2. Verify that all the jar files are in binary mode

I think the most convenient way to solve this problem in 2020 is using another python package. We don't need install any other binary software.

Try this

pip install mysql-connector-python

and then

import mysql.connector_x000D_
_x000D_
mydb = mysql.connector.connect(_x000D_
          host="",_x000D_
          user="",_x000D_
          passwd="",_x000D_
          database=""_x000D_
          )      _x000D_
cursor = mydb.cursor( buffered=True)_x000D_
cursor.execute('show tables;')_x000D_
cursor.execute('insert into test values (null, "a",10)')_x000D_
mydb.commit()_x000D_
mydb.disconnect()

private void setSelectedItem(int actionId) {
    Menu menu = viewBottom.getMenu();
    for (int i = 0, size = menu.size(); i < size; i++) {
        MenuItem menuItem = menu.getItem(i);
        ((MenuItemImpl) menuItem).setExclusiveCheckable(false);
        menuItem.setChecked(menuItem.getItemId() == actionId);
        ((MenuItemImpl) menuItem).setExclusiveCheckable(true);
    }
}

The only 'minus' of the solution is using MenuItemImpl, which is 'internal' to library (though public).

I would give your tds a specific class, e.g. data-cell, and then use something like this:

$("td.data-cell").each(function () {
    // 'this' is now the raw td DOM element
    var txt = $(this).html();
});

There looks to be an issue with the latest version of the pip module pytesseract=0.3.7. I have downgraded it to pytesseract=0.3.6 and don't see the error.

function mode(){
  var input = $("input").val().split(",");
  var mode = [];
  var m = [];
  var p = [];
    for(var x = 0;x< input.length;x++){
      if(m.indexOf(input[x])==-1){
        m[m.length]=input[x];
    }}
  for(var x = 0; x< m.length;x++){
    p[x]=0;
    for(var y = 0; y<input.length;y++){
      if(input[y]==m[x]){
      p[x]++; 
 }}}
 for(var x = 0;x< p.length;x++){
   if(p[x] ==(Math.max.apply(null, p))){
     mode.push(m[x]);
 }} 
$("#output").text(mode);}

This is how I set it up:

1. Open the command prompt(CMD) as administrator.

2. Export the proxy settings :

   set http_proxy=http://username:password@proxyAddress:port

   set https_proxy=https://username:password@proxyAddress:port

3. Install the package you want to install:

   pip install PackageName

For example:

The traceback module and sys.exc_info are overkill for tracking down the source of an exception. That's all in the default traceback. So instead of calling exit(1) just re-raise:

try:
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
except AssertionError:
    print 'Houston, we have a problem.'
    raise

Which gives the following output that includes the offending statement and line number:

Houston, we have a problem.
Traceback (most recent call last):
  File "/tmp/poop.py", line 2, in <module>
    assert "birthday cake" == "ice cream cake", "Should've asked for pie"
AssertionError: Should've asked for pie

Similarly the logging module makes it easy to log a traceback for any exception (including those which are caught and never re-raised):

import logging

try:
    assert False == True 
except AssertionError:
    logging.error("Nothing is real but I can't quit...", exc_info=True)

There is no runtime performance cost to using var. Though, I would suspect there to be a compiling performance cost as the compiler needs to infer the type, though this will most likely be negligable.

From your local machine:

rsync -chavzP --stats [email protected]:/path/to/copy /path/to/local/storage

From your local machine with a non standard ssh port:

rsync -chavzP -e "ssh -p $portNumber" [email protected]:/path/to/copy /local/path

Or from the remote host, assuming you really want to work this way and your local machine is listening on SSH:

rsync -chavzP --stats /path/to/copy [email protected]:/path/to/local/storage

See man rsync for an explanation of my usual switches.

All the above methods will work fine if your content-type is "application/-www-form-urlencoded". But if your content-type is "application/json" then you will have to do the following:

$params = json_decode(file_get_contents('php://input'), true); print_r($params);

Here are two functions that may help if your backup is corrupted, or you have a few partially corrupted backups as well (this may happen if you backup the corrupted objects).

Run both in the repo you're trying to recover.

Standard warning: only use if you're really desperate and you have backed up your (corrupted) repo. This might not resolve anything, but at least should highlight the level of corruption.

fsck_rm_corrupted() {
    corrupted='a'
    while [ "$corrupted" ]; do
        corrupted=$(                                  \
        git fsck --full --no-dangling 2>&1 >/dev/null \
            | grep 'stored in'                          \
            | sed -r 's:.*(\.git/.*)\).*:\1:'           \
        )
        echo "$corrupted"
        rm -f "$corrupted"
    done
}

if [ -z "$1" ]  || [ ! -d "$1" ]; then
    echo "'$1' is not a directory. Please provide the directory of the git repo"
    exit 1
fi

pushd "$1" >/dev/null
fsck_rm_corrupted
popd >/dev/null

and

unpack_rm_corrupted() {
    corrupted='a'
    while [ "$corrupted" ]; do
        corrupted=$(                                  \
        git unpack-objects -r < "$1" 2>&1 >/dev/null \
            | grep 'stored in'                          \
            | sed -r 's:.*(\.git/.*)\).*:\1:'           \
        )
        echo "$corrupted"
        rm -f "$corrupted"
    done
}

if [ -z "$1" ]  || [ ! -d "$1" ]; then
    echo "'$1' is not a directory. Please provide the directory of the git repo"
    exit 1
fi

for p in $1/objects/pack/pack-*.pack; do
    echo "$p"

You can register another directive on top of ng-click which amends the default behaviour of ng-click and stops the event propagation. This way you wouldn't have to add $event.stopPropagation by hand.

app.directive('ngClick', function() {
    return {
        restrict: 'A',
        compile: function($element, attr) {
            return function(scope, element, attr) {
                element.on('click', function(event) {
                    event.stopPropagation();
                });
            };
        }
    }
});

Doing this inline, I set the margin to 0 (ul style="margin:-0px"). The bullets align with paragraph with no overhang.

You can use this piece of code to compute the number of rows a textarea needs:

textarea.rows = 1;
    if (textarea.scrollHeight > textarea.clientHeight)
      textarea.rows = textarea.scrollHeight / textarea.clientHeight;

Compute it on input and window:resize events to get auto-resize effect. Example in Angular:

Template code:

<textarea rows="1" reAutoWrap></textarea>

auto-wrap.directive.ts

import { Directive, ElementRef, HostListener } from '@angular/core';

@Directive({
  selector: 'textarea[reAutoWrap]',
})
export class AutoWrapDirective {

  private readonly textarea: HTMLTextAreaElement;

  constructor(el: ElementRef) {
    this.textarea = el.nativeElement;
  }

  @HostListener('input') onInput() {
    this.resize();
  }

  @HostListener('window:resize') onChange() {
    this.resize();
  }

  private resize() {
    this.textarea.rows = 1;
    if (this.textarea.scrollHeight > this.textarea.clientHeight)
      this.textarea.rows = this.textarea.scrollHeight / this.textarea.clientHeight;
  }

}

The simplest answer is what Paul H said:

d = []
for p in game.players.passing():
    d.append(
        {
            'Player': p,
            'Team': p.team,
            'Passer Rating':  p.passer_rating()
        }
    )

pd.DataFrame(d)

But if you really want to "build and fill a dataframe from a loop", (which, btw, I wouldn't recommend), here's how you'd do it.

d = pd.DataFrame()

for p in game.players.passing():
    temp = pd.DataFrame(
        {
            'Player': p,
            'Team': p.team,
            'Passer Rating': p.passer_rating()
        }
    )

    d = pd.concat([d, temp])

Pojo - Plain old java object

pojo class is an ordinary class without any specialties,class totally loosely coupled from technology/framework.the class does not implements from technology/framework and does not extends from technology/framework api that class is called pojo class.

pojo class can implements interfaces and extend classes but the super class or interface should not be an technology/framework.

Examples :

1.

class ABC{
----
}

ABC class not implementing or extending from technology/framework that's why this is pojo class.

2.

class ABC extends HttpServlet{
---
}

ABC class extending from servlet technology api that's why this is not a pojo class.

3.

class ABC implements java.rmi.Remote{
----
}

ABC class implements from rmi api that's why this is not a pojo class.

4.

class ABC implements java.io.Serializable{
---
}

this interface is part of java language not a part of technology/framework.so this is pojo class.

5.

class ABC extends Thread{
--
}

here thread is also class of java language so this is also a pojo class.

6.

class ABC extends Test{
--
}

if Test class extends or implements from technologies/framework then ABC is also not a pojo class because it inherits the properties of Test class. if Test class is not a pojo class then ABC class also not a pojo class.

7.

now this point is an exceptional case

@Entity
class ABC{
--
}

@Entity is an annotation given by hibernate api or jpa api but still we can call this class as pojo class. class with annotations given from technology/framework is called pojo class by this exceptional case.

Project ---> Clean does the trick in most of the cases. It did in mine.

Change your gmail password and try again, it should work after that.

Don't know why, but every time you change your hosting you have to change your password.

This is the best way (IMHO).

List<String> myArrayList = new ArrayList<String>();
//.....
String[] myArray = myArrayList.toArray(new String[myArrayList.size()]);

This code works also:

String[] myArray = myArrayList.toArray(new String[0]);

But it less effective: the string array is created twice: first time zero-length array is created, then the real-size array is created, filled and returned. So, if since you know the needed size (from list.size()) you should create array that is big enough to put all elements. In this case it is not re-allocated.

To complete @SamSaffron's answer :

You can use class_name with either foreign_key or inverse_of. I personally prefer the more abstract declarative, but it's really just a matter of taste :

class BlogPost
  has_many :images, class_name: "BlogPostImage", inverse_of: :blog_post  
end

and you need to make sure you have the belongs_to attribute on the child model:

class BlogPostImage
  belongs_to :blog_post
end

<form onsubmit="myFunction(event)">
    Name : <input type="text"/>
    <input class="submit" type="submit">
  </form>
  <script>
  function myFunction(event){
    event.preventDefault();
    //code here
  }
  </script>

To get the id from the wildcard match:

$('[id^=pick_]').click(_x000D_
  function(event) {_x000D_
_x000D_
    // Do something with the id # here: _x000D_
    alert('Picked: '+ event.target.id.slice(5));_x000D_
_x000D_
  }_x000D_
);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="pick_1">moo1</div>_x000D_
<div id="pick_2">moo2</div>_x000D_
<div id="pick_3">moo3</div>

You should use gnuplot and be sure to issue the command "set term dumb" after starting up. You can also give a row and column count. Here is the output from gnuplot if you issue "set term dumb 64 10" and then "plot sin(x)":

 

    1 ++-----------****-----------+--***-------+------****--++

It looks better at 79x24 (don't use the 80th column on an 80x24 display: some curses implementations don't always behave well around the last column).

I'm using gnuplot v4, but this should work on slightly older or newer versions.

Default-Values are only considered for parameters NOT given to the function.

So given a function

procedure foo( bar1 IN number DEFAULT 3,
     bar2 IN number DEFAULT 5,
     bar3 IN number DEFAULT 8 );

if you call this procedure with no arguments then it will behave as if called with

foo( bar1 => 3,
     bar2 => 5,
     bar3 => 8 );

but 'NULL' is still a parameter.

foo( 4,
     bar3 => NULL );

This will then act like

foo( bar1 => 4,
     bar2 => 5,
     bar3 => Null );

( oracle allows you to either give the parameter in order they are specified in the procedure, specified by name, or first in order and then by name )

one way to treat NULL the same as a default value would be to default the value to NULL

procedure foo( bar1 IN number DEFAULT NULL,
     bar2 IN number DEFAULT NULL,
     bar3 IN number DEFAULT NULL );

and using a variable with the desired value then

procedure foo( bar1 IN number DEFAULT NULL,
     bar2 IN number DEFAULT NULL,
     bar3 IN number DEFAULT NULL )
AS
     v_bar1    number := NVL( bar1, 3);
     v_bar2    number := NVL( bar2, 5);
     v_bar3    number := NVL( bar3, 8);

You could try to find it via the command line.

find / -type f -name "php.ini"

Or you could add the following to a .htaccess file in the root of your site.

php_value max_input_vars 6000
php_value suhosin.get.max_vars 6000
php_value suhosin.post.max_vars 6000
php_value suhosin.request.max_vars 6000

IIS now has

Idle Time-out Action : Suspend setting

Suspending is just freezes the process and it is much more efficient than the destroying the process.

A simple but dirty trick is to simply add the offset you want to the image you are using as background. it's not maintainable, but it gets the job done.

partition() may be better then split() for this purpose as it has the better predicable results for situations you have no delimiter or more delimiters.

I wrote this function after looking Integer.java source code.

private static int stringSize(int x) {
    final int[] sizeTable = {9, 99, 999, 9_999, 99_999, 999_999, 9_999_999,
            99_999_999, 999_999_999, Integer.MAX_VALUE};
    for (int i = 0; ; ++i) {
        if (x <= sizeTable[i]) {
            return i + 1;
        }
    }
}

Recommending SequenceEqual is ok, but thinking that it may ever be faster than usual for(;;) loop is too naive.

Here is the reflected code:

public static bool SequenceEqual<TSource>(this IEnumerable<TSource> first, 
    IEnumerable<TSource> second, IEqualityComparer<TSource> comparer)
{
    if (comparer == null)
    {
        comparer = EqualityComparer<TSource>.Default;
    }
    if (first == null)
    {
        throw Error.ArgumentNull("first");
    }
    if (second == null)
    {
        throw Error.ArgumentNull("second");
    }
    using (IEnumerator<TSource> enumerator = first.GetEnumerator())     
    using (IEnumerator<TSource> enumerator2 = second.GetEnumerator())
    {
        while (enumerator.MoveNext())
        {
            if (!enumerator2.MoveNext() || !comparer.Equals(enumerator.Current, enumerator2.Current))
            {
                return false;
            }
        }
        if (enumerator2.MoveNext())
        {
            return false;
        }
    }
    return true;
}

As you can see it uses 2 enumerators and fires numerous method calls which seriously slow everything down. Also it doesn't check length at all, so in bad cases it can be ridiculously slower.

Compare moving two iterators with beautiful

if (a1[i] != a2[i])

and you will know what I mean about performance.

It can be used in cases where performance is really not so critical, maybe in unit test code, or in cases of some short list in rarely called methods.

Pandas (and numpy) allow for boolean indexing, which will be much more efficient:

In [11]: df.loc[df['col1'] >= 1, 'col1']
Out[11]: 
1    1
2    2
Name: col1

In [12]: df[df['col1'] >= 1]
Out[12]: 
   col1  col2
1     1    11
2     2    12

In [13]: df[(df['col1'] >= 1) & (df['col1'] <=1 )]
Out[13]: 
   col1  col2
1     1    11

If you want to write helper functions for this, consider something along these lines:

In [14]: def b(x, col, op, n): 
             return op(x[col],n)

In [15]: def f(x, *b):
             return x[(np.logical_and(*b))]

In [16]: b1 = b(df, 'col1', ge, 1)

In [17]: b2 = b(df, 'col1', le, 1)

In [18]: f(df, b1, b2)
Out[18]: 
   col1  col2
1     1    11

Update: pandas 0.13 has a query method for these kind of use cases, assuming column names are valid identifiers the following works (and can be more efficient for large frames as it uses numexpr behind the scenes):

In [21]: df.query('col1 <= 1 & 1 <= col1')
Out[21]:
   col1  col2
1     1    11

This is a fairly old thread, but since I was reinstalling my Visual Studio 2015 Community today, I thought I might add some info on what to use on VS2015, or what might work in general.

To see which instances were installed by default, type sqllocaldb info inside a command prompt. On my machine, I get two instances, the first one named MSSQLLocalDB.

C:\>sqllocaldb info
MSSQLLocalDB
ProjectsV13

You can also create a new instance if you wish, using sqllocaldb create "some_instance_name", but the default one will work just fine:

// if not using a verbatim string literal, don't forget to escape backslashes
@"Server=(localdb)\MSSQLLocalDB;Integrated Security=true;"

Since you are using JSON.NET, personally I would go with serialization so that you can have Intellisense support for your object. You'll need a class that represents your JSON structure. You can build this by hand, or you can use something like json2csharp to generate it for you:

e.g.

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public class RootObject
{
    public List<Person> People { get; set; }
}

Then, you can simply call JsonConvert's methods to deserialize the JSON into an object:

RootObject instance = JsonConvert.Deserialize<RootObject>(json);

Then you have Intellisense:

var firstName = instance.People[0].FirstName;
var lastName = instance.People[0].LastName;

The reason reset and revert tend to come up a lot in the same conversations is because different version control systems use them to mean different things.

In particular, people who are used to SVN or P4 who want to throw away uncommitted changes to a file will often reach for revert before being told that they actually want reset.

Similarly, the revert equivalent in other VCSes is often called rollback or something similar - but "rollback" can also mean "I want to completely discard the last few commits", which is appropriate for reset but not revert. So, there's a lot of confusion where people know what they want to do, but aren't clear on which command they should be using for it.

As for your actual questions about revert...

Okay, you're going to use git revert but how?

git revert first-bad-commit..last-bad-commit

And after running git revert do you have to do something else after? Do you have to commit the changes revert made or does revert directly commit to the repo or what??

By default, git revert prompts you for a commit message and then commits the results. This can be overridden. I quote the man page:

--edit

With this option, git revert will let you edit the commit message prior to committing the revert. This is the default if you run the command from a terminal.

--no-commit

Usually the command automatically creates some commits with commit log messages stating which commits were reverted. This flag applies the changes necessary to revert the named commits to your working tree and the index, but does not make the commits. In addition, when this option is used, your index does not have to match the HEAD commit. The revert is done against the beginning state of your index.

This is useful when reverting more than one commits' effect to your index in a row.

In particular, by default it creates a new commit for each commit you're reverting. You can use revert --no-commit to create changes reverting all of them without committing those changes as individual commits, then commit at your leisure.

You can do something like this

    Declare @min int=0, @max int =0 --Initialize variable here which will be use in loop 
    Declare @Recordid int,@TO nvarchar(30),@Subject nvarchar(250),@Body nvarchar(max)  --Initialize variable here which are useful for your

    select ROW_NUMBER() OVER(ORDER BY [Recordid] )  AS Rownumber, Recordid, [To], [Subject], [Body], [Flag]
            into #temp_Mail_Mstr FROM Mail_Mstr where Flag='1'  --select your condition with row number & get into a temp table

    set @min = (select MIN(Rownumber) from #temp_Mail_Mstr); --Get minimum row number from temp table
    set @max = (select Max(Rownumber) from #temp_Mail_Mstr);  --Get maximum row number from temp table

   while(@min <= @max)
   BEGIN
        select @Recordid=Recordid, @To=[To], @Subject=[Subject], @Body=Body from #temp_Mail_Mstr where Rownumber=@min

        -- You can use your variables (like @Recordid,@To,@Subject,@Body) here  
        -- Do your work here 

        set @min=@min+1 --Increment of current row number

Take a look at this site: http://www.json.org/

Also, you can try calling JSON.stringify() on one of your objects from the browser to see the json format. You'd have to do this in the console or a test page.

The following solution is:

• briefest. Somewhat similar to here. It's also minimal: The table in the DIV is orthogonal to your question.
• fastest: getElementById is called once at the outset. This may or may not suit your purposes.
• It uses pure JavaScript (i.e. without JQuery).
• It uses a button. Your taste may vary.
• extensible: it's ready to add more DIVs, sharing the code.

mydiv = document.getElementById("showmehideme");_x000D_
_x000D_
function showhide(d) {_x000D_
    d.style.display = (d.style.display !== "none") ? "none" : "block";_x000D_
}

#mydiv { background-color: #ddd; }

<button id="button" onclick="showhide(mydiv)">Show/Hide</button>_x000D_
<div id="showmehideme">_x000D_
    This div will show and hide on button click._x000D_
</div>
