This will not work java -cp lib\*.jar -jar myproject.jar. You have to put it jar by jar.

So in case of commons-codec-1.3.jar.

java -cp lib/commons-codec-1.3.jar;lib/next_jar.jar and so on.

The other solution might be putting all your jars to ext directory of your JRE. This is ok if you are using a standalone JRE. If you are using the same JRE for running more than one application I do not recommend doing it.

1. Create a new shortcut:

2. Paste the following path:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="c:\temp\chrome"

3. Name it:

Unsafe Chrome.exe

Now you have an unsafe version of Google Chrome on desktop to use it for debugging front-end applications without any CORS problems.

Calling JavaScript function on code behind i.e. On Page_Load

ClientScript.RegisterStartupScript(GetType(), "Javascript", "javascript:FUNCTIONNAME(); ", true);

If you have UpdatePanel there then try like this

ScriptManager.RegisterStartupScript(GetType(), "Javascript", "javascript:FUNCTIONNAME(); ", true);

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.

int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
    for(int i=0; i<=names.size()-1; ++i) {
        if(names[i]==req_name){
            cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
            return 0;
        }
        else if(names[i]!=req_name && i==names.size()-1) {
            cout<<"That name is not an element in this vector"<<'\n';
        } else {
            continue;
        }
    }

Hey please add code in your project,it is easy and i think will solve your problem.

    int count = 10;

    private void timer1_Tick(object sender, EventArgs e)
    {
        count--;
        if (count != 0 && count > 0)
        {
            label1.Text = count / 60 + ":" + ((count % 60) >= 10 ? (count % 60).ToString() : "0" + (count % 60));
        }
        else
        {
            label1.Text = "game over";

        }

    }

    private void Form1_Load(object sender, EventArgs e)
    {
        timer1 = new System.Windows.Forms.Timer();
        timer1.Interval = 1;

        timer1.Tick += new EventHandler(timer1_Tick);

    }

If you want to load the file, as part of your app functionality, then the best approach would be to include and reference to that file.

Another approach is to ask for the file, and load it during runtime. This can be done with the FileAPI. There is also another StackOverflow answer about using it: How to open a local disk file with Javascript?

I will include a slightly modified version for using it in React:

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: null
    };
    this.handleFileSelect = this.handleFileSelect.bind(this);
  }

  displayData(content) {
    this.setState({data: content});
  }

  handleFileSelect(evt) {
    let files = evt.target.files;
    if (!files.length) {
      alert('No file select');
      return;
    }
    let file = files[0];
    let that = this;
    let reader = new FileReader();
    reader.onload = function(e) {
      that.displayData(e.target.result);
    };
    reader.readAsText(file);
  }

  render() {
    const data = this.state.data;
    return (
      <div>
        <input type="file" onChange={this.handleFileSelect}/>
        { data && <p> {data} </p> }
      </div>
    );
  }
}

Here is yet another way without Invoke-Expression but with two variables (command:string and parameters:array). It works fine for me. Assume 7z.exe is in the system path.

$cmd = '7z.exe'
$prm = 'a', '-tzip', 'c:\temp\with space\test1.zip', 'C:\TEMP\with space\changelog'

& $cmd $prm

If the command is known (7z.exe) and only parameters are variable then this will do

$prm = 'a', '-tzip', 'c:\temp\with space\test1.zip', 'C:\TEMP\with space\changelog'

& 7z.exe $prm

BTW, Invoke-Expression with one parameter works for me, too, e.g. this works

$cmd = '& 7z.exe a -tzip "c:\temp\with space\test2.zip" "C:\TEMP\with space\changelog"'

Invoke-Expression $cmd

P.S. I usually prefer the way with a parameter array because it is easier to compose programmatically than to build an expression for Invoke-Expression.

To add rows to existing DataTable in Dataset:

DataRow drPartMtl = DSPartMtl.Tables[0].NewRow();
drPartMtl["Group"] = "Group";
drPartMtl["BOMPart"] = "BOMPart";
DSPartMtl.Tables[0].Rows.Add(drPartMtl);

This is working for me in Angular 7. It is based on the --main option of the ng command. I am not sure if this option is undocumented and possibly subject to change, but it works for me. I put a line in my package.json file in scripts section. There using the --main option of with the ng test command, I specify the path to the .spec.ts file I want to execute. For example

"test 1": "ng test --main E:/WebRxAngularClient/src/app/test/shared/my-date-utils.spec.ts",

You can run the script as you run any such script. I run it in Webstorm by clicking on "test 1" in the npm section.

Since Steve Tjoa's answer always pops up first and mostly lonely when I search for multiple y-axes at Google, I decided to add a slightly modified version of his answer. This is the approach from this matplotlib example.

Reasons:

• His modules sometimes fail for me in unknown circumstances and cryptic intern errors.
• I don't like to load exotic modules I don't know (mpl_toolkits.axisartist, mpl_toolkits.axes_grid1).
• The code below contains more explicit commands of problems people often stumble over (like single legend for multiple axes, using viridis, ...) rather than implicit behavior.

import matplotlib.pyplot as plt 

# Create figure and subplot manually
# fig = plt.figure()
# host = fig.add_subplot(111)

# More versatile wrapper
fig, host = plt.subplots(figsize=(8,5)) # (width, height) in inches
# (see https://matplotlib.org/3.3.3/api/_as_gen/matplotlib.pyplot.subplots.html)
    
par1 = host.twinx()
par2 = host.twinx()
    
host.set_xlim(0, 2)
host.set_ylim(0, 2)
par1.set_ylim(0, 4)
par2.set_ylim(1, 65)
    
host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

color1 = plt.cm.viridis(0)
color2 = plt.cm.viridis(0.5)
color3 = plt.cm.viridis(.9)

p1, = host.plot([0, 1, 2], [0, 1, 2],    color=color1, label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2],    color=color2, label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], color=color3, label="Velocity")

lns = [p1, p2, p3]
host.legend(handles=lns, loc='best')

# right, left, top, bottom
par2.spines['right'].set_position(('outward', 60))

# no x-ticks                 
par2.xaxis.set_ticks([])

# Sometimes handy, same for xaxis
#par2.yaxis.set_ticks_position('right')

# Move "Velocity"-axis to the left
# par2.spines['left'].set_position(('outward', 60))
# par2.spines['left'].set_visible(True)
# par2.yaxis.set_label_position('left')
# par2.yaxis.set_ticks_position('left')

host.yaxis.label.set_color(p1.get_color())
par1.yaxis.label.set_color(p2.get_color())
par2.yaxis.label.set_color(p3.get_color())

# Adjust spacings w.r.t. figsize
fig.tight_layout()
# Alternatively: bbox_inches='tight' within the plt.savefig function 
#                (overwrites figsize)

# Best for professional typesetting, e.g. LaTeX
plt.savefig("pyplot_multiple_y-axis.pdf")
# For raster graphics use the dpi argument. E.g. '[...].png", dpi=200)'

Sometimes using libraries are cool when you do not want to reinvent the wheel, but in this case one can do the same job with fewer lines of code and easier to read compared to using libraries. Here is a different approach which I find very easy to use.

1. In this example, I use StreamReader to read the file
2. Regex to detect the delimiter from each line(s).
3. An array to collect the columns from index 0 to n

using (StreamReader reader = new StreamReader(fileName))
    {
        string line; 

        while ((line = reader.ReadLine()) != null)
        {
            //Define pattern
            Regex CSVParser = new Regex(",(?=(?:[^\"]*\"[^\"]*\")*(?![^\"]*\"))");

            //Separating columns to array
            string[] X = CSVParser.Split(line);

            /* Do something with X */
        }
    }

Your site is probably already in the list where the browser is told not to prompt for saving a password. In firefox, Options -> Security -> Remember password for sites[check box] - exceptions[button]

I found this example quite helpful:

https://github.com/visionmedia/express/blob/master/examples/error-pages/index.js

So it is actually this part:

// "app.router" positions our routes
// above the middleware defined below,
// this means that Express will attempt
// to match & call routes _before_ continuing
// on, at which point we assume it's a 404 because
// no route has handled the request.

app.use(app.router);

// Since this is the last non-error-handling
// middleware use()d, we assume 404, as nothing else
// responded.

// $ curl http://localhost:3000/notfound
// $ curl http://localhost:3000/notfound -H "Accept: application/json"
// $ curl http://localhost:3000/notfound -H "Accept: text/plain"

app.use(function(req, res, next){
  res.status(404);

  // respond with html page
  if (req.accepts('html')) {
    res.render('404', { url: req.url });
    return;
  }

  // respond with json
  if (req.accepts('json')) {
    res.send({ error: 'Not found' });
    return;
  }

  // default to plain-text. send()
  res.type('txt').send('Not found');
});

You'll want to do a transform as such:

with JavaScript:

document.getElementById(yourtarget).setAttribute("transform", "scale(2.0)");

With CSS:

#yourtarget {
  transform:scale(2.0);
  -webkit-transform:scale(2.0);
}

Wrap your SVG Page in a Group tag as such and target it to manipulate the whole page:

<svg>
  <g id="yourtarget">
    your svg page
  </g>
</svg>

Note: Scale 1.0 is 100%

Another method utilizing the dplyr package:

library(dplyr)
df <- mtcars %>%
        filter(mpg > 25)

Without the chain (%>%) operator:

library(dplyr)
df <- filter(mtcars, mpg > 25)

Although this question is very old, but I see still there are no exact answer. I will try to answer the question here.

I believe the question in short here is how to set the proxy settings for the Apache commons HttpClient (org.apache.commons.httpclient.HttpClient).

Code snippet below should work :

HttpClient client = new HttpClient();
HostConfiguration hostConfiguration = client.getHostConfiguration();
hostConfiguration.setProxy("localhost", 8080);
client.setHostConfiguration(hostConfiguration);

"new" and "original" are different dicts, that's why you can update just one of them.. The items are shallow-copied, not the dict itself.

I was having the same issue, but with Glide. When I was going to disconnect from wifi and reconnect (just like it was suggested here), I noticed that I was in Airplane mode ???

The following code as an example of a replacement for $scope.emit() or $scope.broadcast() in Angular 2 using a shared service to handle events.

import {Injectable} from 'angular2/core';
import * as Rx from 'rxjs/Rx';

@Injectable()
export class EventsService {
    constructor() {
        this.listeners = {};
        this.eventsSubject = new Rx.Subject();

        this.events = Rx.Observable.from(this.eventsSubject);

        this.events.subscribe(
            ({name, args}) => {
                if (this.listeners[name]) {
                    for (let listener of this.listeners[name]) {
                        listener(...args);
                    }
                }
            });
    }

    on(name, listener) {
        if (!this.listeners[name]) {
            this.listeners[name] = [];
        }

        this.listeners[name].push(listener);
    }

    off(name, listener) {
        this.listeners[name] = this.listeners[name].filter(x => x != listener);
    }

    broadcast(name, ...args) {
        this.eventsSubject.next({
            name,
            args
        });
    }
}

Example usage:

Broadcast:

function handleHttpError(error) {
    this.eventsService.broadcast('http-error', error);
    return ( Rx.Observable.throw(error) );
}

Listener:

import {Inject, Injectable} from "angular2/core";
import {EventsService}      from './events.service';

@Injectable()
export class HttpErrorHandler {
    constructor(eventsService) {
        this.eventsService = eventsService;
    }

    static get parameters() {
        return [new Inject(EventsService)];
    }

    init() {
        this.eventsService.on('http-error', function(error) {
            console.group("HttpErrorHandler");
            console.log(error.status, "status code detected.");
            console.dir(error);
            console.groupEnd();
        });
    }
}

It can support multiple arguments:

this.eventsService.broadcast('something', "Am I a?", "Should be b", "C?");

this.eventsService.on('something', function (a, b, c) {
   console.log(a, b, c);
});

This is the only code that worked for me:

public static void adjustTabLayoutBounds(final TabLayout tabLayout,
                                         final DisplayMetrics displayMetrics){

    final ViewTreeObserver vto = tabLayout.getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

        @Override
        public void onGlobalLayout() {

            tabLayout.getViewTreeObserver().removeOnGlobalLayoutListener(this);

            int totalTabPaddingPlusWidth = 0;
            for(int i=0; i < tabLayout.getTabCount(); i++){

                final LinearLayout tabView = ((LinearLayout)((LinearLayout) tabLayout.getChildAt(0)).getChildAt(i));
                totalTabPaddingPlusWidth += (tabView.getMeasuredWidth() + tabView.getPaddingLeft() + tabView.getPaddingRight());
            }

            if (totalTabPaddingPlusWidth <= displayMetrics.widthPixels){

                tabLayout.setTabMode(TabLayout.MODE_FIXED);
                tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

            }else{
                tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
            }

            tabLayout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        }
    });
}

The DisplayMetrics can be retrieved using this:

public DisplayMetrics getDisplayMetrics() {

    final WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
    final Display display = wm.getDefaultDisplay();
    final DisplayMetrics displayMetrics = new DisplayMetrics();

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
        display.getMetrics(displayMetrics);

    }else{
        display.getRealMetrics(displayMetrics);
    }

    return displayMetrics;
}

And your TabLayout XML should look like this (don't forget to set tabMaxWidth to 0):

<android.support.design.widget.TabLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/tab_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:tabMaxWidth="0dp"/>

You cannot save it as local file without using server side logic. But if that fits your needs, you could look at local storage of html5 or us a javascript plugin as jStorage

Use the (excellent) JSON-Java library from json.org then

JSONObject json = new JSONObject(str);
String xml = XML.toString(json);

toString can take a second argument to provide the name of the XML root node.

This library is also able to convert XML to JSON using XML.toJSONObject(java.lang.String string)

Try rename command:

rename 's/_h.png/_half.png/' *.png

Update:

example usage:

create some content

$ mkdir /tmp/foo
$ cd /tmp/foo
$ touch one_h.png two_h.png three_h.png
$ ls 
one_h.png  three_h.png  two_h.png

test solution:

$ rename 's/_h.png/_half.png/' *.png
$ ls
one_half.png  three_half.png  two_half.png

Another difference:

A table var can only be accessed from statements within the procedure that creates it, not from other procedures called by that procedure or nested dynamic SQL (via exec or sp_executesql).

A temp table's scope, on the other hand, includes code in called procedures and nested dynamic SQL.

If the table created by your procedure must be accessible from other called procedures or dynamic SQL, you must use a temp table. This can be very handy in complex situations.

document.getElementsByClassName returns a node list. So you'll have to iterate over the list and bind the event to individual elements. Like this...

var buttons = document.getElementsByClassName("navButton");

for(var i = 0; i < buttons.length; ++i){
    buttons[i].onmouseover = function() {
        this.setAttribute("class", "active");
        this.setAttribute("src", "images/arrows/top_o.png");
    }
}

Easy with perl! If you want to get line 1, 3 and 5 from a file, say /etc/passwd:

perl -e 'while(<>){if(++$l~~[1,3,5]){print}}' < /etc/passwd

I had an almost identical error:

Error while connecting to MySQL: Authentication plugin 'caching_sha2_password' is not supported

The solution for me was simple:

My db username/password creds were incorrect. The error was not descriptive of the problem, so I thought I would share this in case someone else runs into this.

Ok, I deleted my previous answer because finally it was not what willlangford was looking for, but I made my point that maybe we were all misunderstanding the question.

I also thought of the SELECT DISTINCT... thing at first, but it seemed too weird to me that someone needed to know how many people had a different number of pets than the rest... thats why I thought that maybe the question was not clear enough.

So, now that the real question meaning is clarified, making a subquery for this its quite an overhead, I would preferably use a GROUP BY clause.

Imagine you have the table customer_pets like this:

+-----------------------+
|  customer  |   pets   |
+------------+----------+
| customer1  |    2     |
| customer2  |    3     |
| customer3  |    2     |
| customer4  |    2     |
| customer5  |    3     |
| customer6  |    4     |
+------------+----------+

then

SELECT count(customer) AS num_customers, pets FROM customer_pets GROUP BY pets

would return:

+----------------------------+
|  num_customers  |   pets   |
+-----------------+----------+
|        3        |    2     |
|        2        |    3     |
|        1        |    4     |
+-----------------+----------+

as you need.

All of the answers here show only the memory percentage for the PID.

Here's an example of how to get the rss memory usage in KB for all apache processes, replace "grep apache" with "grep PID" if you just want to watch a specific PID:

watch -n5 "ps aux -y | grep apache | awk '{print \$2,\$6}'"

This prints:

Every 5.0s: ps aux -y | grep apache | awk '{print $2,$6}'

I'm guessing your code failed BEFORE import sys, so it can't find it when you handle the exception.

Also, you should indent the your code whithin the try block.

try:

import sys
# .. other safe imports
try:
    import numpy as np
    # other unsafe imports
except ImportError:
    print "Error: missing one of the libraries (numpy, pyfits, scipy, matplotlib)"
    sys.exit()

I think you should use python wheels for distribution instead of egg now.

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

TextWatcher didn't work for me as it kept firing for every EditText and messing up each others values.

Here is my solution:

public class ConsultantTSView extends Activity {
    .....

    //Submit is called when I push submit button.
    //I wanted to retrieve all EditText(tsHours) values in my HoursList

    public void submit(View view){

        ListView TSDateListView = (ListView) findViewById(R.id.hoursList);
        String value = ((EditText) TSDateListView.getChildAt(0).findViewById(R.id.tsHours)).getText().toString();
    }
}

Hence by using the getChildAt(xx) method you can retrieve any item in the ListView and get the individual item using findViewById. And it will then give the most recent value.

Some code to walk through a list of titles (circularily or one-shot):

    var titles = [
            " title",
            "> title",
            ">> title",
            ">>> title"
    ];

    // option 1:
    function titleAniCircular(i) {
            // from first to last title and back again, forever
            i = (!i) ? 0 : (i*1+1) % titles.length;
            $('title').html(titles[i]);
            setTimeout(titleAniCircular, 1000, [i]);
    };

    // option 2:
    function titleAniSequence(i) {
            // from first to last title and stop
            i = (!i) ? 0 : (i*1+1);
            $('title').html(titles[i]);
            if (i<titles.length-1) setTimeout(titleAniSequence, 1000, [i]);
    };

    // then call them when you like.
    // e.g. to call one on document load, uncomment one of the rows below:

    //$(document).load( titleAniCircular() );
    //$(document).load( titleAniSequence() );

You can use this.getClass().getSimpleName(), like so:

import java.lang.reflect.Field;

public class Test {

    int x;
    int y;  

    public void getClassName() {
        String className = this.getClass().getSimpleName(); 
        System.out.println("Name:" + className);
    }

    public void getAttributes() {
        Field[] attributes = this.getClass().getDeclaredFields();   
        for(int i = 0; i < attributes.length; i++) {
            System.out.println("Declared Fields" + attributes[i]);    
        }
    }

    public static void main(String args[]) {

        Test t = new Test();
        t.getClassName();
        t.getAttributes();
    }
}

Frustratingly the Numpy package published to PyPI won't install on most Windows computers https://github.com/numpy/numpy/issues/5479

Instead:

1. Download the Numpy wheel for your Python version from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
2. Install it from the command line pip install numpy-1.10.2+mkl-cp35-none-win_amd64.whl

<input id="item123" class="firstName" type="text" value="Hello there" data-someattr="CoolExample" />

$(".firstName").on('change keyup paste', function () {
   var element = $(this);
   console.log(element);
   var dataAttribute = $(element).attr("data-someattr");
   console.log("someattr: " + dataAttribute );
});

I recommend use this keyword in order to get access to the entire element so your are able do everything you need with this element.

Task.GetAwaiter().GetResult() is preferred over Task.Wait and Task.Result because it propagates exceptions rather than wrapping them in an AggregateException. However, all three methods cause the potential for deadlock and thread pool starvation issues. They should all be avoided in favor of async/await.

The quote below explains why Task.Wait and Task.Result don't simply contain the exception propagation behavior of Task.GetAwaiter().GetResult() (due to a "very high compatibility bar").

As I mentioned previously, we have a very high compatibility bar, and thus we’ve avoided breaking changes. As such, Task.Wait retains its original behavior of always wrapping. However, you may find yourself in some advanced situations where you want behavior similar to the synchronous blocking employed by Task.Wait, but where you want the original exception propagated unwrapped rather than it being encased in an AggregateException. To achieve that, you can target the Task’s awaiter directly. When you write “await task;”, the compiler translates that into usage of the Task.GetAwaiter() method, which returns an instance that has a GetResult() method. When used on a faulted Task, GetResult() will propagate the original exception (this is how “await task;” gets its behavior). You can thus use “task.GetAwaiter().GetResult()” if you want to directly invoke this propagation logic.

https://blogs.msdn.microsoft.com/pfxteam/2011/09/28/task-exception-handling-in-net-4-5/

“GetResult” actually means “check the task for errors”

In general, I try my best to avoid synchronously blocking on an asynchronous task. However, there are a handful of situations where I do violate that guideline. In those rare conditions, my preferred method is GetAwaiter().GetResult() because it preserves the task exceptions instead of wrapping them in an AggregateException.

Just throw an empty, hidden div onto your html page and give it an ID. Then you can use that for your jQuery UI dialog. You can populate the text just like you normally would with any jquery call.

public void expand(final View v) {
        ScaleAnimation scaleAnimation = new ScaleAnimation(1, 1, 1, 0, 0, 0);
        scaleAnimation.setDuration(250);
        scaleAnimation.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                v.setVisibility(View.INVISIBLE);
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });
        v.startAnimation(scaleAnimation);
    }

    public void collapse(final View v) {
        ScaleAnimation scaleAnimation = new ScaleAnimation(1, 1, 0, 1, 0, 0);
        scaleAnimation.setDuration(250);
        scaleAnimation.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                v.setVisibility(View.VISIBLE);
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });
        v.startAnimation(scaleAnimation);
    }

rising_edge is defined as:

FUNCTION rising_edge  (SIGNAL s : std_ulogic) RETURN BOOLEAN IS
BEGIN
    RETURN (s'EVENT AND (To_X01(s) = '1') AND
                        (To_X01(s'LAST_VALUE) = '0'));
END;

FUNCTION To_X01  ( s : std_ulogic ) RETURN  X01 IS
BEGIN
    RETURN (cvt_to_x01(s));
END;

CONSTANT cvt_to_x01 : logic_x01_table := (
                     'X',  -- 'U'
                     'X',  -- 'X'
                     '0',  -- '0'
                     '1',  -- '1'
                     'X',  -- 'Z'
                     'X',  -- 'W'
                     '0',  -- 'L'
                     '1',  -- 'H'
                     'X'   -- '-'
                    );

If your clock only goes from 0 to 1, and from 1 to 0, then rising_edge will produce identical code. Otherwise, you can interpret the difference.

Personally, my clocks only go from 0 to 1 and vice versa. I find rising_edge(clk) to be more descriptive than the (clk'event and clk = '1') variant.

Got sick of the installation troubles with MySQLdb and tried pymysql instead.

Easy setup;

git clone https://github.com/petehunt/PyMySQL.git
python setup.py install

And APIs are pretty much the same.

Another solution:

z = 10
for x in range (z):
   y = z-x
   print y

Result:

10
9
8
7
6
5
4
3
2
1

Tip: If you are using this method to count back indices in a list, you will want to -1 from the 'y' value, as your list indices will begin at 0.

I also solved my problem with Mosh's answer and I thought PeterB's answer was a bit of since it used an enum as foreign key. Remember that you will need to add a new migration after adding this code.

I can also recommend this blog post for other solutions:

http://www.kianryan.co.uk/2013/03/orphaned-child/

Code:

public class Child
{
    [Key, Column(Order = 0), DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    public string Heading { get; set; }
    //Add other properties here.

    [Key, Column(Order = 1)]
    public int ParentId { get; set; }

    public virtual Parent Parent { get; set; }
}

MVC 5 is already built into Visual Studios 2013.

1. Open a new project, on the left make sure you are under Templates > Visual C# > Web not Templates > Visual C# > Web > Visual Studios 2012.

2. Important: Now look near the top of the new project dialog box and select .NET 4.5 or higher. Once under web and the proper framework is selected click ASP.NET Web Application in the middle pane. Click OK

3. This will bring you to a page where you can select MVC as the project and start the wizard.

Get the Sothink SWF decompiler. Not free, but worth it. Recently used it to decompile an SWF that I had lost the fla for, and I could completely round-trip swf-fla and back!

str is meant to produce a string representation of the object's data. If you're writing your own class and you want str to work for you, add:

def __str__(self):
    return "Some descriptive string"

print str(myObj) will call myObj.__str__().

repr is a similar method, which generally produces information on the class info. For most core library object, repr produces the class name (and sometime some class information) between angle brackets. repr will be used, for example, by just typing your object into your interactions pane, without using print or anything else.

You can define the behavior of repr for your own objects just like you can define the behavior of str:

def __repr__(self):
    return "Some descriptive string"

>>> myObj in your interactions pane, or repr(myObj), will result in myObj.__repr__()

I think its simpler:

$('submit').click(function(e){
if (e.isValid())
   e.preventDefault();
//your code.
}

this will stop the submit until form is valid.

You can use .map: http://jsfiddle.net/9ndcL/1/.

// array of text of each td

var texts = $("td").map(function() {
    return $(this).text();
});

None of the given answers helped me to resolve the issue. Posting my answer here; may be helpful for someone

Declare private var popGesture: UIGestureRecognizer? as global variable in your viewcontroller. Then implement the code in viewDidAppear and viewWillDisappear methods

override func viewDidAppear(animated: Bool) {

    super.viewDidAppear(animated)

    if self.navigationController!.respondsToSelector(Selector("interactivePopGestureRecognizer")) {

        self.popGesture = navigationController!.interactivePopGestureRecognizer
        self.navigationController!.view.removeGestureRecognizer(navigationController!.interactivePopGestureRecognizer!)
    }
}


override func viewWillDisappear(animated: Bool) {

    super.viewWillDisappear(animated)

    if self.popGesture != nil {
        navigationController!.view.addGestureRecognizer(self.popGesture!)
    }
}

This will disable swipe back in iOS v8.x onwards

Just do delete. This is from the SQLite documentation:

The Truncate Optimization

"When the WHERE is omitted from a DELETE statement and the table being deleted has no triggers, SQLite uses an optimization to erase the entire table content without having to visit each row of the table individually. This "truncate" optimization makes the delete run much faster. Prior to SQLite version 3.6.5, the truncate optimization also meant that the sqlite3_changes() and sqlite3_total_changes() interfaces and the count_changes pragma will not actually return the number of deleted rows. That problem has been fixed as of version 3.6.5."

Your return data approach is correct, that's an example of promise chaining. If you return a promise from your .then() callback, JavaScript will resolve that promise and pass the data to the next then() callback.

Just be careful and make sure you handle errors with .catch(). Promise.all() rejects as soon as one of the promises in the array rejects.

I think this is what you are looking for -

select Address1+Address2 as CompleteAddress from YourTable
where Address1+Address2 like '%YourSearchString%'

To prevent a compound word being created when we append address1 with address2, you can use this -

select Address1 + ' ' + Address2 as CompleteAddress from YourTable 
where Address1 + ' ' + Address2 like '%YourSearchString%'

So, '123 Center St' and 'Apt 3B' will not be '123 Center StApt 3B' but will be '123 Center St Apt 3B'.

You could throw the enum value and string into an STL map. Then you could use it like so.

   return myStringMap[Enum::Apple];

× stands for × in html. Use &times to get &times

Filezilla just released a Pro version of their FTP client. It connects to S3 buckets in a streamlined FTP like experience. I use it myself (no affiliation whatsoever) and it works great.

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

ULIMIT configuration:

1. Login by root
   
2. vi security/limits.conf

3. Make Below entry

   Ulimit configuration start for website user

   website   soft   nofile    8192
   website   hard   nofile    8192
   website   soft   nproc    4096
   website   hard   nproc    8192
   website   soft   core    unlimited
   website   hard   core    unlimited
   

4. Make Below entry for ALL USER

   Ulimit configuration for every user

   *   soft   nofile    8192
   *   hard   nofile    8192
   *   soft   nproc    4096
   *   hard   nproc    8192
   *   soft   core    unlimited
   *   hard   core    unlimited
   

5. After modifying the file, user need to logoff and login again to see the new values.

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

You can also use DataTable - you can define then the number of columns and their types and then add rows http://www.dotnetperls.com/datatable

Tieme put a lot of effort into his excellent answer, but I think the core of the OP's question is how these technologies relate to PHP rather than how each technology works.

PHP is the most used language in web development besides the obvious client side HTML, CSS, and Javascript. Yet PHP has 2 major issues when it comes to real-time applications:

1. PHP started as a very basic CGI. PHP has progressed very far since its early stage, but it happened in small steps. PHP already had many millions of users by the time it became the embed-able and flexible C library that it is today, most of whom were dependent on its earlier model of execution, so it hasn't yet made a solid attempt to escape the CGI model internally. Even the command line interface invokes the PHP library (libphp5.so on Linux, php5ts.dll on Windows, etc) as if it still a CGI processing a GET/POST request. It still executes code as if it just has to build a "page" and then end its life cycle. As a result, it has very little support for multi-thread or event-driven programming (within PHP userspace), making it currently unpractical for real-time, multi-user applications.

Note that PHP does have extensions to provide event loops (such as libevent) and threads (such as pthreads) in PHP userspace, but very, very, few of the applications use these.

2. PHP still has significant issues with garbage collection. Although these issues have been consistently improving (likely its greatest step to end the life cycle as described above), even the best attempts at creating long-running PHP applications require being restarted on a regular basis. This also makes it unpractical for real-time applications.

PHP 7 will be a great step to fix these issues as well, and seems very promising as a platform for real-time applications.

I did not manage to find a way to do it directly.

Instead I imported the bak file into SQL Server 2008 Express, and then used MySQL Migration Toolkit.

Worked like a charm!

I same thing happen with me, If your code is correct and then also give 405 error. this error due to some authorization problem. go to authorization menu and change to "Inherit auth from parent".

try this:

select * from mytable where convert(varchar, mycolumn) = ''

i hope help u!

df[df$aged <= df$laclen, ] 

Should do the trick. The square brackets allow you to index based on a logical expression.

You almost got it. You are hiding the rows within the active sheet. which is okay. But a better way would be add where it is.

Rows("52:55").EntireRow.Hidden = False

becomes

activesheet.Rows("52:55").EntireRow.Hidden = False

i've had weird things happen without it. As for making it automatic. You need to use the worksheet_change event within the sheet's macro in the VBA editor (not modules, double click the sheet1 to the far left of the editor.) Within that sheet, use the drop down menu just above the editor itself (there should be 2 listboxes). The listbox to the left will have the events you are looking for. After that just throw in the macro. It should look like the below code,

Private Sub Worksheet_Change(ByVal Target As Range)
test1
end Sub

That's it. Anytime you change something, it will run the macro test1.

This can occur on android too not just computers. Was browsing using Kiwi when the site I was on began to endlessly redirect so I cut net access to close it out and noticed my phone had DL'd something f.txt in my downloaded files.

Deleted it and didn't open.

You can use the file utility to give you an indication of the type of line endings.

Unix:

$ file testfile1.txt
testfile.txt: ASCII text

"DOS":

$ file testfile2.txt
testfile2.txt: ASCII text, with CRLF line terminators

To convert from "DOS" to Unix:

$ dos2unix testfile2.txt

To convert from Unix to "DOS":

$ unix2dos testfile1.txt

Converting an already converted file has no effect so it's safe to run blindly (i.e. without testing the format first) although the usual disclaimers apply, as always.

Following width worked well in HTML5: -

<table >
  <tr>
    <th style="min-width:120px">Month</th>
    <th style="min-width:60px">Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>February</td>
    <td>$80</td>
  </tr>
</table>

Please note that

• TD tag is without CSS style.

Using Ellipsis

Text(
  "This is a long text",
  overflow: TextOverflow.ellipsis,
),

Using Fade

Text(
  "This is a long text",
  overflow: TextOverflow.fade,
  maxLines: 1,
  softWrap: false,
),

Using Clip

Text(
  "This is a long text",
  overflow: TextOverflow.clip,
  maxLines: 1,
  softWrap: false,
),

Note:

If you are using Text inside a Row, you can put above Text inside Expanded like:

Expanded(
  child: AboveText(),
)

<input type="file" onchange="getBaseUrl()">

function getBaseUrl ()  {
    var file = document.querySelector('input[type=file]')['files'][0];
    var reader = new FileReader();
    var baseString;
    reader.onloadend = function () {
        baseString = reader.result;
        console.log(baseString); 
    };
    reader.readAsDataURL(file);
}

Cron is so named "deamon" (same as service under Win).

Most likely cron is already installed on your system (if it is a Linux/Unix system).

Look here: http://www.comptechdoc.org/os/linux/startupman/linux_sucron.html

or there http://en.wikipedia.org/wiki/Cron

for more details.

Here's a comparison of the two:

Entity Type

• SQS: Queue (Similar to JMS)
• SNS: Topic (Pub/Sub system)

Message consumption

• SQS: Pull Mechanism - Consumers poll and pull messages from SQS
• SNS: Push Mechanism - SNS Pushes messages to consumers

Use Case

• SQS: Decoupling two applications and allowing parallel asynchronous processing
• SNS: Fanout - Processing the same message in multiple ways

Persistence

• SQS: Messages are persisted for some (configurable) duration if no consumer is available (maximum two weeks), so the consumer does not have to be up when messages are added to queue.
• SNS: No persistence. Whichever consumer is present at the time of message arrival gets the message and the message is deleted. If no consumers are available then the message is lost after a few retries.

Consumer Type

• SQS: All the consumers are typically identical and hence process the messages in the exact same way (each message is processed once by one consumer, though in rare cases messages may be resent)
• SNS: The consumers might process the messages in different ways

Sample applications

• SQS: Jobs framework: The Jobs are submitted to SQS and the consumers at the other end can process the jobs asynchronously. If the job frequency increases, the number of consumers can simply be increased to achieve better throughput.
• SNS: Image processing. If someone uploads an image to S3 then watermark that image, create a thumbnail and also send a Thank You email. In that case S3 can publish notifications to an SNS topic with three consumers listening to it. The first one watermarks the image, the second one creates a thumbnail and the third one sends a Thank You email. All of them receive the same message (image URL) and do their processing in parallel.

Let us assume you have a margin-bottom property set to 20px / 20% / 20em. To get the value as a number there are two options:

Option 1:

parseInt($('#some_DOM_element_ID').css('margin-bottom'), 10);

The parseInt() function parses a string and returns an integer. Don't change the 10 found in the above function (known as a "radix") unless you know what you are doing.

Example Output will be: 20 (if margin-bottom set in px) for % and em it will output the relative number based on current Parent Element / Font size.

Option 2 (I personally prefer this option)

parseFloat($('#some_DOM_element_ID').css('margin-bottom'));

Example Output will be: 20 (if margin-bottom set in px) for % and em it will output the relative number based on current Parent Element / Font size.

The parseFloat() function parses a string and returns a floating point number.

The parseFloat() function determines if the first character in the specified string is a number. If it is, it parses the string until it reaches the end of the number, and returns the number as a number, not as a string.

The advantage of Option 2 is that if you get decimal numbers returned (e.g. 20.32322px) you will get the number returned with the values behind the decimal point. Useful if you need specific numbers returned, for example if your margin-bottom is set in em or %

AFAIK, in the epic DOS era there is a header file named graphics.h shipped with Borland Turbo C++ suite. If it is true, then you are out of luck because we're now in Windows era.

For application/msword and application/vnd.ms-excel, when I deleted the size restriction:

...it worked ok.

MAKE THIS YOUR config.js file code

CKEDITOR.editorConfig = function( config ) {

   //   config.enterMode = 2; //disabled <p> completely

A Python 2+3 compatible solution is:

import sys

if sys.version_info[0] >= 3:
    from urllib.request import urlretrieve
else:
    # Not Python 3 - today, it is most likely to be Python 2
    # But note that this might need an update when Python 4
    # might be around one day
    from urllib import urlretrieve

# Get file from URL like this:
urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

The notion of multi-module projects is there to service the needs of codependent segments of a project. Such a client depends on the services which in turn depends on say EJBs or data-access routines. You could group your continuous integration (CI) tests in this manner. I would rationalize that by saying that the CI tests need to be in lock-step with application logic changes.

Suppose your project is structured as:

project-root
  |
  + --- ci
  |
  + --- client
  |
  + --- server

The project-root/pom.xml defines modules

<modules>
  <module>ci</module>
  <module>client</module>
  <module>server</module>
</modules>

The ci/pom.xml defines profiles such as:

... 
<profiles>
  <profile>
    <id>default</id>
    <activation>
      <activeByDefault>true</activeByDefault>
    </activation>
    <plugin>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
         <skip>true</skip>
       </configuration>
     </plugin>
  </profile>
  <profile>
    <id>CI</id>
    <plugin>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
         <skip>false</skip>
       </configuration>
     </plugin>
  </profile>
</profiles>

This will result in Maven skipping tests in this module except when the profile named CI is active. Your CI server must be instructed to execute mvn clean package -P CI. The Maven web site has an in-depth explanation of the profiling mechanism.

CGRect Can be simply created using an instance of a CGPoint or CGSize, thats given below.

let rect = CGRect(origin: CGPoint(x: 0,y :0), size: CGSize(width: 100, height: 100))  

// Or

let rect = CGRect(origin: .zero, size: CGSize(width: 100, height: 100))

Or if we want to specify each value in CGFloat or Double or Int, we can use this method.

let rect = CGRect(x: 0, y: 0, width: 100, height: 100) // CGFloat, Double, Int

CGPoint Can be created like this.

 let point = CGPoint(x: 0,y :0) // CGFloat, Double, Int

CGSize Can be created like this.

let size = CGSize(width: 100, height: 100) // CGFloat, Double, Int

Also size and point with 0 as the values, it can be done like this.

let size = CGSize.zero // width = 0, height = 0
let point = CGPoint.zero // x = 0, y = 0, equal to CGPointZero
let rect = CGRect.zero // equal to CGRectZero

CGRectZero & CGPointZero replaced with CGRect.zero & CGPoint.zero in Swift 3.0.

var rootEle = document.querySelector("html");
var ele = angular.element(rootEle); 

scope() We can fetch the $scope from the element (or its parent) by using the scope() method on the element:

var scope = ele.scope();

injector()

var injector = ele.injector();

With this injector, we can then then instantiate any Angular object inside of our app, such as services, other controllers, or any other object

You need to check out a previous version from before you deleted the files. Try git checkout HEAD^ to checkout the last revision.

If you only have one reference to a string and you concatenate another string to the end, CPython now special cases this and tries to extend the string in place.

The end result is that the operation is amortized O(n).

e.g.

s = ""
for i in range(n):
    s+=str(i)

used to be O(n^2), but now it is O(n).

From the source (bytesobject.c):

void
PyBytes_ConcatAndDel(register PyObject **pv, register PyObject *w)
{
    PyBytes_Concat(pv, w);
    Py_XDECREF(w);
}


/* The following function breaks the notion that strings are immutable:
   it changes the size of a string.  We get away with this only if there
   is only one module referencing the object.  You can also think of it
   as creating a new string object and destroying the old one, only
   more efficiently.  In any case, don't use this if the string may
   already be known to some other part of the code...
   Note that if there's not enough memory to resize the string, the original
   string object at *pv is deallocated, *pv is set to NULL, an "out of
   memory" exception is set, and -1 is returned.  Else (on success) 0 is
   returned, and the value in *pv may or may not be the same as on input.
   As always, an extra byte is allocated for a trailing \0 byte (newsize
   does *not* include that), and a trailing \0 byte is stored.
*/

int
_PyBytes_Resize(PyObject **pv, Py_ssize_t newsize)
{
    register PyObject *v;
    register PyBytesObject *sv;
    v = *pv;
    if (!PyBytes_Check(v) || Py_REFCNT(v) != 1 || newsize < 0) {
        *pv = 0;
        Py_DECREF(v);
        PyErr_BadInternalCall();
        return -1;
    }
    /* XXX UNREF/NEWREF interface should be more symmetrical */
    _Py_DEC_REFTOTAL;
    _Py_ForgetReference(v);
    *pv = (PyObject *)
        PyObject_REALLOC((char *)v, PyBytesObject_SIZE + newsize);
    if (*pv == NULL) {
        PyObject_Del(v);
        PyErr_NoMemory();
        return -1;
    }
    _Py_NewReference(*pv);
    sv = (PyBytesObject *) *pv;
    Py_SIZE(sv) = newsize;
    sv->ob_sval[newsize] = '\0';
    sv->ob_shash = -1;          /* invalidate cached hash value */
    return 0;
}

It's easy enough to verify empirically.

$ python -m timeit -s"s=''" "for i in xrange(10):s+='a'"
1000000 loops, best of 3: 1.85 usec per loop
$ python -m timeit -s"s=''" "for i in xrange(100):s+='a'"
10000 loops, best of 3: 16.8 usec per loop
$ python -m timeit -s"s=''" "for i in xrange(1000):s+='a'"
10000 loops, best of 3: 158 usec per loop
$ python -m timeit -s"s=''" "for i in xrange(10000):s+='a'"
1000 loops, best of 3: 1.71 msec per loop
$ python -m timeit -s"s=''" "for i in xrange(100000):s+='a'"
10 loops, best of 3: 14.6 msec per loop
$ python -m timeit -s"s=''" "for i in xrange(1000000):s+='a'"
10 loops, best of 3: 173 msec per loop

It's important however to note that this optimisation isn't part of the Python spec. It's only in the cPython implementation as far as I know. The same empirical testing on pypy or jython for example might show the older O(n**2) performance .

$ pypy -m timeit -s"s=''" "for i in xrange(10):s+='a'"
10000 loops, best of 3: 90.8 usec per loop
$ pypy -m timeit -s"s=''" "for i in xrange(100):s+='a'"
1000 loops, best of 3: 896 usec per loop
$ pypy -m timeit -s"s=''" "for i in xrange(1000):s+='a'"
100 loops, best of 3: 9.03 msec per loop
$ pypy -m timeit -s"s=''" "for i in xrange(10000):s+='a'"
10 loops, best of 3: 89.5 msec per loop

So far so good, but then,

$ pypy -m timeit -s"s=''" "for i in xrange(100000):s+='a'"
10 loops, best of 3: 12.8 sec per loop

ouch even worse than quadratic. So pypy is doing something that works well with short strings, but performs poorly for larger strings.

Sounds like you want a view instead of altering actual table data.

Coalesce(NullIf(rtrim(Address.Country),''),'United States')

This will force your column to be null if it is actually an empty string (or blank string) and then the coalesce will have a null to work with.

Method Object JComboBox.getSelectedItem() returns a value that is wrapped by Object type so you have to cast it accordingly.

Syntax:

YourType varName = (YourType)comboBox.getSelectedItem();`
String value = comboBox.getSelectedItem().toString();

On behalf of the Visual Studio tool, we can easily generate C# properties using an online tool called C# property generator.

url-pattern is used in web.xml to map your servlet to specific URL. Please see below xml code, similar code you may find in your web.xml configuration file.

<servlet>
    <servlet-name>AddPhotoServlet</servlet-name>  //servlet name
    <servlet-class>upload.AddPhotoServlet</servlet-class>  //servlet class
</servlet>
 <servlet-mapping>
    <servlet-name>AddPhotoServlet</servlet-name>   //servlet name
    <url-pattern>/AddPhotoServlet</url-pattern>  //how it should appear
</servlet-mapping>

If you change url-pattern of AddPhotoServlet from /AddPhotoServlet to /MyUrl. Then, AddPhotoServlet servlet can be accessible by using /MyUrl. Good for the security reason, where you want to hide your actual page URL.

Java Servlet url-pattern Specification:

1. A string beginning with a '/' character and ending with a '/*' suffix is used for path mapping.
2. A string beginning with a '*.' prefix is used as an extension mapping.
3. A string containing only the '/' character indicates the "default" servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.
4. All other strings are used for exact matches only.

Work for me :)

function jsonEncodeArray( $array ){
    array_walk_recursive( $array, function(&$item) { 
       $item = utf8_encode( $item ); 
    });
    return json_encode( $array );
}

Well, while creating a custom view engine can work for this, still you can have an alternative:

• Decide what you need to show by default.
• That something has controller and action (and Area), right?
• Open that Area registration and add something like this:

public override void RegisterArea(AreaRegistrationContext context)
{
    //this makes it work for the empty url (just domain) to act as current Area.
    context.MapRoute(
        "Area_empty",
        "",
        new { controller = "Home", action = "Index", id = UrlParameter.Optional },
        namespaces: new string[] { "Area controller namespace" }
    );
        //other routes of the area
}

Cheers!

Maybe this is what you're looking for?

string = "line #1"\
         "line #2"\
         "line #3"

p string # => "line #1line #2line #3"

I don't know if this question is still relevant, but there is such possibility in Postman now. They added it a few months ago.

All you need is create simple .js file and run it via node.js. It looks like this:

var path = require('path'),
  async = require('async'), //https://www.npmjs.com/package/async
  newman = require('newman'),

  parametersForTestRun = {
    collection: path.join(__dirname, 'postman_collection.json'), // your collection
    environment: path.join(__dirname, 'postman_environment.json'), //your env
  };

parallelCollectionRun = function(done) {
  newman.run(parametersForTestRun, done);
};

// Runs the Postman sample collection thrice, in parallel.
async.parallel([
    parallelCollectionRun,
    parallelCollectionRun,
    parallelCollectionRun
  ],
  function(err, results) {
    err && console.error(err);

    results.forEach(function(result) {
      var failures = result.run.failures;
      console.info(failures.length ? JSON.stringify(failures.failures, null, 2) :
        `${result.collection.name} ran successfully.`);
    });
  });

Then just run this .js file ('node fileName.js' in cmd).

For WINDOWS (shell) users with Notepad++ (checked with v6.8.3) you can correct the specific file using the option - Edit -> EOL conversion -> Unix/OSX format

And save your file again.

Edit: still works in v7.5.1 (Aug 29 2017)

It boils down to whether the CPU in your machine has the the VT bit (Virtualization), and the BIOS enables you to turn it on. For instance, my laptop is a Core 2 Duo which is capable of using this. However, my BIOS doesn't enable me to turn it on.

Note that I've read that turning on this feature can slow normal operations down by 10-12%, which is why it's normally turned off.

From the command prompt, start up sqlcmd:

sqlcmd -S <server> -i C:\<your file here>.sql 

Just replace <server> with the location of your SQL box and <your file here> with the name of your script. Don't forget, if you're using a SQL instance the syntax is:

sqlcmd -S <server>\instance.

Here is the list of all arguments you can pass sqlcmd:

Sqlcmd            [-U login id]          [-P password]
  [-S server]            [-H hostname]          [-E trusted connection]
  [-d use database name] [-l login timeout]     [-t query timeout] 
  [-h headers]           [-s colseparator]      [-w screen width]
  [-a packetsize]        [-e echo input]        [-I Enable Quoted Identifiers]
  [-c cmdend]            [-L[c] list servers[clean output]]
  [-q "cmdline query"]   [-Q "cmdline query" and exit] 
  [-m errorlevel]        [-V severitylevel]     [-W remove trailing spaces]
  [-u unicode output]    [-r[0|1] msgs to stderr]
  [-i inputfile]         [-o outputfile]        [-z new password]
  [-f  | i:[,o:]] [-Z new password and exit] 
  [-k[1|2] remove[replace] control characters]
  [-y variable length type display width]
  [-Y fixed length type display width]
  [-p[1] print statistics[colon format]]
  [-R use client regional setting]
  [-b On error batch abort]
  [-v var = "value"...]  [-A dedicated admin connection]
  [-X[1] disable commands, startup script, environment variables [and exit]]
  [-x disable variable substitution]
  [-? show syntax summary] 

Create an object holding following properties with an appropriate name.

1. message
2. timestamp
3. count
4. version

and use this as a value in your map.

Also consider overriding the equals() and hashCode() method accordingly if you do not want object equality to be used for comparison (e.g. when inserting values into your map).

The documentation for this is good if not a little difficult to find.

Facebook Graph API - Page Tokens

After initializing node's fbgraph, you can run:

var facebookAccountID = yourAccountIdHere 

graph
.setOptions(options)
.get(facebookAccountId + "/accounts", function(err, res) {
  console.log(res); 
});

and receive a JSON response with the token you want to grab, located at:

res.data[0].access_token

For those from 2018 and beyond, using npm version 5 or later: edit your package-lock.json: remove the library from "requires" section and add it under "dependencies".

For example, you want deglob package to use glob package version 3.2.11 instead of its current one. You open package-lock.json and see:

"deglob": {
  "version": "2.1.0",
  "resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
  "integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
  "requires": {
    "find-root": "1.1.0",
    "glob": "7.1.2",
    "ignore": "3.3.5",
    "pkg-config": "1.1.1",
    "run-parallel": "1.1.6",
    "uniq": "1.0.1"
  }
},

Remove "glob": "7.1.2", from "requires", add "dependencies" with proper version:

"deglob": {
  "version": "2.1.0",
  "resolved": "https://registry.npmjs.org/deglob/-/deglob-2.1.0.tgz",
  "integrity": "sha1-TUSr4W7zLHebSXK9FBqAMlApoUo=",
  "requires": {
    "find-root": "1.1.0",
    "ignore": "3.3.5",
    "pkg-config": "1.1.1",
    "run-parallel": "1.1.6",
    "uniq": "1.0.1"
  },
  "dependencies": {
    "glob": {
      "version": "3.2.11"
    }
  }
},

Now remove your node_modules folder, run npm install and it will add missing parts to the "dependencies" section.

You should try this (test, works at least in Firefox):

html2canvas(document.body,{
   onrendered:function(canvas){
      document.body.appendChild(canvas);
   }
});

Im running these lines of code to get the full browser screen (only the visible screen, not the hole site):

var w=window, d=document, e=d.documentElement, g=d.getElementsByTagName('body')[0];
var y=w.innerHeight||e.clientHeight||g.clientHeight;

html2canvas(document.body,{

If the size of the circles corresponds to the square of the parameter in s=parameter, then assign a square root to each element you append to your size array, like this: s=[1, 1.414, 1.73, 2.0, 2.24] such that when it takes these values and returns them, their relative size increase will be the square root of the squared progression, which returns a linear progression.

If I were to square each one as it gets output to the plot: output=[1, 2, 3, 4, 5]. Try list interpretation: s=[numpy.sqrt(i) for i in s]

Unfortunately not... However, there's a simple trick if it's going to be less than 24 hours.

Oracle assumes that a number added to a date is in days. Convert the number of seconds into days. Add the current day, then use the to_date function to take only the parts your interested in. Assuming you have x seconds:

select to_char(sysdate + (x / ( 60 * 60 * 24 ) ), 'HH24:MI:SS')
  from dual

This won't work if there's more than 24 hours, though you can remove the current data again and get the difference in days, hours, minutes and seconds.

If you want something like: 51:10:05, i.e. 51 hours, 10 minutes and 5 seconds then you're going to have to use trunc.

Once again assuming that you have x seconds...

• The number of hours is trunc(x / 60 / 60)
• The number of minutes is trunc((x - ( trunc(x / 60 / 60) * 60 * 60 )) / 60)
• The number of seconds is therefore the x - hours * 60 * 60 - minutes * 60

Leaving you with:

with hrs as (
  select x, trunc(x / 60 / 60) as h
    from dual
         )
 , mins as (
  select x, h, trunc((x - h * 60 * 60) / 60) as m
    from hrs
         )
select h, m, x - (h * 60 * 60) - (m * 60)
  from mins

I've set up a SQL Fiddle to demonstrate.

press windows+R open RUN Window

services.msc 

find SQL Server(SQLEXPRESS) right click on that and start the service then check

inet_ntoa() converts a in_addr to string:

The inet_ntoa function converts an (Ipv4) Internet network address into an ASCII string in Internet standard dotted-decimal format.

inet_addr() does the reverse job

The inet_addr function converts a string containing an IPv4 dotted-decimal address into a proper address for the IN_ADDR structure

PS this the first result googling "in_addr to string"!

this is supported from version hive 0.14

INSERT INTO TABLE pd_temp(dept,make,cost,id,asmb_city,asmb_ct,retail) VALUES('production','thailand',10,99202,'northcarolina','usa',20)

You cannot mix JS and PHP that way, PHP is rendered before the page is sent to the browser (i.e. before the JS is run)

You can use window.location to change your current page.

$('.entry a:first').click(function() {
    window.location = "http://google.ca";
});

The function returns a FileStream object. So you could use it's return value to open your StreamWriter or close it using the proper method of the object:

File.Create(myPath).Close();

Setting isBodyHtml to true allows you to use HTML tags in the message body:

msg = new MailMessage("[email protected]",
                "[email protected]", "Message from PSSP System",
                "This email sent by the PSSP system<br />" +
                "<b>this is bold text!</b>");

msg.IsBodyHtml = true;

I found request.env['HTTP_X_FORWARDED_FOR'] very useful too in cases when request.remote_ip returns 127.0.0.1

Your question answers itself ;) If og_date contains the date, it's probably a string, so og_date.value is undefined.

Simply use og_date.split('-') instead of og_date.value.split('-')

Parcelable is sort of a standard in Android development. But not because of speed

Parcelable is recommended approach for data transfers. But if you use serializable correctly as shown in this repo, you will see that serializable is sometimes even faster then parcelable. Or at least timings are comparable.

Is Parcelable faster then Serializable?

No, if serialization is done right.

Usual Java serialization on an average Android device (if done right *) is about 3.6 times faster than Parcelable for writes and about 1.6 times faster for reads. Also it proves that Java Serialization (if done right) is fast storage mechanism that gives acceptable results even with relatively large object graphs of 11000 objects with 10 fields each.

* The sidenote is that usually everybody who blindly states that "Parcelable is mush faster" compares it to default automatic serialization, which uses much reflection inside. This is unfair comparison, because Parcelable uses manual (and very complicated) procedure of writing data to the stream. What is usually not mentioned is that standard Java Serializable according to the docs can also be done in a manual way, using writeObject() and readObject() methods. For more info see JavaDocs. This is how it should be done for the best performance.

So, if serializable is faster and easier to implement, why android has parcelable at all?

The reason is native code. Parcelable is created not just for interprocess communication. It also can be used for intercode communication. You can send and recieve objects from C++ native layer. That's it.

What should you choose? Both will work good. But I think that Parcelable is better choice since it is recommended by google and as you can see from this thread is much more appreciated.

input.next() takes in the first whitsepace-delimited word of the input string. So by design it does what you've described. Try input.nextLine().

Since I wrote the MSDN article you are referring to, I guess I have to answer this one.

First, I anticipated this question and that's why I wrote a blog post that shows a more or less real use case for ExpandoObject: Dynamic in C# 4.0: Introducing the ExpandoObject.

Shortly, ExpandoObject can help you create complex hierarchical objects. For example, imagine that you have a dictionary within a dictionary:

Dictionary<String, object> dict = new Dictionary<string, object>();
Dictionary<String, object> address = new Dictionary<string,object>();
dict["Address"] = address;
address["State"] = "WA";
Console.WriteLine(((Dictionary<string,object>)dict["Address"])["State"]);

The deeper is the hierarchy, the uglier is the code. With ExpandoObject it stays elegant and readable.

dynamic expando = new ExpandoObject();
expando.Address = new ExpandoObject();
expando.Address.State = "WA";
Console.WriteLine(expando.Address.State);

Second, as it was already pointed out, ExpandoObject implements INotifyPropertyChanged interface which gives you more control over properties than a dictionary.

Finally, you can add events to ExpandoObject like here:

class Program
{
   static void Main(string[] args)
   {
       dynamic d = new ExpandoObject();

       // Initialize the event to null (meaning no handlers)
       d.MyEvent = null;

       // Add some handlers
       d.MyEvent += new EventHandler(OnMyEvent);
       d.MyEvent += new EventHandler(OnMyEvent2);

       // Fire the event
       EventHandler e = d.MyEvent;

       e?.Invoke(d, new EventArgs());
   }

   static void OnMyEvent(object sender, EventArgs e)
   {
       Console.WriteLine("OnMyEvent fired by: {0}", sender);
   }

   static void OnMyEvent2(object sender, EventArgs e)
   {
       Console.WriteLine("OnMyEvent2 fired by: {0}", sender);
   }
}

Also, keep in mind that nothing is preventing you from accepting event arguments in a dynamic way. In other words, instead of using EventHandler, you can use EventHandler<dynamic> which would cause the second argument of the handler to be dynamic.

Use Fiddler and grab the view state in the response and paste it into the bottom left text box then decode.

that is called hint in android use android:hint="Enter Name"

Instead of using the windows load event use the ready event on the document.

$(document).ready(function(){[...]});

This should fire when everything in the DOM is ready to go, including media content fully loaded.

@Autowired is an annotation introduced in Spring 2.5, and it's used only for injection.

For example:

class A {

    private int id;

    // With setter and getter method
}

class B {

    private String name;

    @Autowired // Here we are injecting instance of Class A into class B so that you can use 'a' for accessing A's instance variables and methods.
    A a;

    // With setter and getter method

    public void showDetail() {
        System.out.println("Value of id form A class" + a.getId(););
    }
}

If you are only looking for a refresh rate for the GOOGLEFINANCE function, keep in mind that data delays can be up to 20 minutes (per Google Finance Disclaimer).

Single-symbol refresh rate (using GoogleClock)

Here is a modified version of the refresh action, taking the data delay into consideration, to save on unproductive refresh cycles.

=GoogleClock(GOOGLEFINANCE(symbol,"datadelay"))

For example, with:

• SYMBOL: GOOG
• DATA DELAY: 15 (minutes)

then

=GoogleClock(GOOGLEFINANCE("GOOG","datadelay"))

Results in a dynamic data-based refresh rate of:

=GoogleClock(15)

Multi-symbol refresh rate (using GoogleClock)

If your sheet contains a number of rows of symbols, you could add a datadelay column for each symbol and use the lowest value, for example:

=GoogleClock(MIN(dataDelayValuesNamedRange))

Where dataDelayValuesNamedRange is the absolute reference or named reference of the range of cells that contain the data delay values for each symbol (assuming these values are different).

Without GoogleClock()

The GoogleClock() function was removed in 2014 and replaced with settings setup for refreshing sheets. At present, I have confirmed that replacement settings is only on available in Sheets from when accessed from a desktop browser, not the mobile app (I'm using Google's mobile Sheets app updated 2016-03-14).

(This part of the answer is based on, and portions copied from, Google Docs Help)

To change how often "some" Google Sheets functions update:

1. Open a spreadsheet. Click File > Spreadsheet settings.
2. In the RECALCULATION section, choose a setting from the drop-down menu.
3. Setting options are:
   • On change
   • On change and every minute
   • On change and every hour
4. Click SAVE SETTINGS.

NOTE External data functions recalculate at the following intervals:

• ImportRange: 30 minutes
• ImportHtml, ImportFeed, ImportData, ImportXml: 1 hour
• GoogleFinance: 2 minutes

The references in earlier sections to the display and use of the datadelay attribute still apply, as well as the concepts for more efficient coding of sheets.

On a positive note, the new refresh option continues to be refreshed by Google servers regardless of whether you have the sheet loaded or not. That's a positive for shared sheets for sure; even more so for Google Apps Scripts (GAS), where GAS is used in workflow code or referenced data is used as a trigger for an event.

[*] in my understanding so far (I am currently testing this)

I am using IIS and mysql (directly downloaded, without wamp or xampp) My php was installed in c:\php I was getting the error of "call to undefined function mysql_connect()" For me the change of extension_dir worked. This is what I did. In the php.ini, Originally, I had this line

; On windows: extension_dir = "ext"

I changed it to:

; On windows: extension_dir = "C:\php\ext"

And it worked. Of course, I did the other things also like uncommenting the dll extensions etc, as explained in others remarks.

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

If you are using Databinding on layout you can get the context from holder. An exemple below.

@Override
public void onBindViewHolder(@NonNull GenericViewHolder holder, int position) {
    View currentView = holder.binding.getRoot().findViewById(R.id.cycle_count_manage_location_line_layout);// id of your root layout
    currentView.setBackgroundColor(ContextCompat.getColor(holder.binding.getRoot().getContext(), R.color.light_green));
}

You can use getFragmentManager().popBackStack() in basic Fragment to go back.

Let's say you have a tag someplace on the page which contains your loading message:

<div id='loadingmessage' style='display:none'>
  <img src='loadinggraphic.gif'/>
</div>

You can add two lines to your ajax call:

function getData(p){
    var page=p;
    $('#loadingmessage').show();  // show the loading message.
    $.ajax({
        url: "loadData.php?id=<? echo $id; ?>",
        type: "POST",
        cache: false,
        data: "&page="+ page,
        success : function(html){
            $(".content").html(html);
            $('#loadingmessage').hide(); // hide the loading message
        }
    });

The link mentioned by Subimage was right on the money for me. It suggested changing the virtual host tag, ie, from <VirtualHost myserver.example.com:443> to <VirtualHost _default_:443>

Error code: ssl_error_rx_record_too_long

This usually means the implementation of SSL on your server is not correct. The error is usually caused by a server side problem which the server administrator will need to investigate.

Below are some things we recommend trying.

• Ensure that port 443 is open and enabled on your server. This is the standard port for https communications.

• If SSL is using a non-standard port then FireFox 3 can sometimes give this error. Ensure SSL is running on port 443.

• If using Apache2 check that you are using port 443 for SSL. This can be done by setting the ports.conf file as follows

  Listen 80
  Listen 443 https
  

• Make sure you do not have more than one SSL certificate sharing the same IP. Please ensure that all SSL certificates utilise their own dedicated IP.

• If using Apache2 check your vhost config. Some users have reported changing <VirtualHost> to _default_ resolved the error.

That fixed my problem. It's rare that I google an error message and get the first hit with the right answer! :-)

In addition to the above, these are some other solutions that other folks have found were causing the issue:

• Make sure that your SSL certificate is not expired

• Try to specify the Cipher:

  SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM:+SSLv3

I do not think that what you are looking for is provided by SciPy. I would write the code myself, in this situation.

The spline interpolation and smoothing from scipy.interpolate are quite nice and might be quite helpful in fitting peaks and then finding the location of their maximum.

Create a "module" object and declare variables in there. Unlike class-objects that have to be instantiated each time, the module objects are always available. Therefore, a public variable, function, or property in a "module" will be available to all the other objects in the VBA project, macro, Excel formula, or even within a MS Access JET-SQL query def.

gettimeofday will return time accurate to microseconds within the resolution of the system clock. You might also want to check out the High Res Timers project on SourceForge.

Quite similar approve as already posted above. However it's easier to read.

/**
 * Remove all empty spaces from array a string array
 * @param arr array
 * @return array without ""
 */
public static String[] removeAllEmpty(String[] arr) {
    if (arr == null)
        return arr;

    String[] result = new String[arr.length];
    int amountOfValidStrings = 0;

    for (int i = 0; i < arr.length; i++) {
        if (!arr[i].equals(""))
            result[amountOfValidStrings++] = arr[i];
    }

    result = Arrays.copyOf(result, amountOfValidStrings);

    return result;
}

1. Go to Setting/Apps/ Search for your app and uninstall...
2. open command prompt and "adb uninstall "

It´s worked for me

From the api on GridLayout:

The container is divided into equal-sized rectangles, and one component is placed in each rectangle.

Try using FlowLayout or GridBagLayout for your set size to be meaningful. Also, @Serplat is correct. You need to use setPreferredSize( Dimension ) instead of setSize( int, int ).

    JPanel displayPanel = new JPanel();
    // JPanel displayPanel = new JPanel( new GridLayout( 4, 2 ) );
    // JPanel displayPanel = new JPanel( new BorderLayout() );
    // JPanel displayPanel = new JPanel( new GridBagLayout() );

    JTextField titleText = new JTextField( "title" );

    titleText.setPreferredSize( new Dimension( 200, 24 ) );

    // For FlowLayout and GridLayout, uncomment:
    displayPanel.add( titleText );

    // For BorderLayout, uncomment:
    // displayPanel.add( titleText, BorderLayout.NORTH );

    // For GridBagLayout, uncomment:
    // displayPanel.add( titleText, new GridBagConstraints( 0, 0, 1, 1, 1.0,
    // 1.0, GridBagConstraints.CENTER, GridBagConstraints.NONE,
    // new Insets( 0, 0, 0, 0 ), 0, 0 ) );

second_value -= first_value;
first_value +=  second_value;
second_value -= first_value;
second_value *= -1;

To show child or sibling elements it's possible with CSS only. If you use :hover before combinators (+, ~, >, space). Then the style applies not to hovered element.

HTML

<body>
  <div class="trigger">
    Hover here.
  </div>
  <div class="hidden">
    This message shows up.
  </div>
</body>

CSS

.hidden { display: none; }
.trigger:hover + .hidden { display: inline; }

In your flask code, you should ideally specify the MIME type as often as possible, as well:

return html_page_str, 200, {'ContentType':'text/html'}

return json.dumps({'success':True}), 200, {'ContentType':'application/json'}

...etc

Off course an old question. But I have a simple solution where no need of Looping, CTE, Table variables etc.

DECLARE @MyVar datetime = '1/1/2010'    
SELECT @MyVar

SELECT DATEADD (DD,NUMBER,@MyVar) 
FROM master.dbo.spt_values 
WHERE TYPE='P' AND NUMBER BETWEEN 0 AND 4 
ORDER BY NUMBER

Note : spt_values is a Mircrosoft's undocumented table. It has numbers for every type. Its not suggestible to use as it can be removed in any new versions of sql server without prior information, since it is undocumented. But we can use it as quick workaround in some scenario's like above.

The AT command would do that but that's what the Scheduled Tasks gui is for. Enter "help at" in a cmd window for details.

I accidentally created my own component with the same name as a library's component.

When I used my IDE to auto-import the library for the component, I chose the wrong library.

Therefore this error was complaining, that I was re-declaring the component.

I fixed by importing from my own component's code, instead of the library.

I could also fix by naming differently: avoid ambiguity.

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));

In JavaScript you can use template literals:

let value = 100;
console.log(`The size is ${ value }`);

You're not parsing a string, you're parsing an already-parsed object :)

var obj1 = JSON.parse('{"creditBalance":0,...,"starStatus":false}');
//                    ^                                          ^
//                    if you want to parse, the input should be a string 

var obj2 = {"creditBalance":0,...,"starStatus":false};
// or just use it directly.

To run the python file on mac.

1. Open the preferences in atom ide. To open the preferences press 'command + . ' ( ? + , )

2. Click on the install in the preferences to install packages.

3. Search for package "script" and click on install

4. Now open the python file(with .py extension ) you want to run and press 'control + r ' (^ + r)

As Jon Skeet and Marc Gravell already mentioned, you can simple take a contains condition. But in case of your like query, it's very dangerous to take a Single() statement, because that implies that you only find 1 result. In case of more results, you'll receive a nice exception :)

So I would prefer using FirstOrDefault() instead of Single():

var first = Database.DischargePorts.FirstOrDefault(p => p.PortName.Contains("BALTIMORE"));
var portcode = first != null ? first.PortCode : string.Empty;

If website on small devices behavior like desktop screen then you have to put this meta tag into header before

<meta name="viewport" content="width=device-width, initial-scale=1">

For media queries you can set this as

this will cover your all mobile/cellphone widths

 @media only screen and (min-width: 200px) and (max-width: 767px)  {
    //Put your CSS here for 200px to 767px width devices (cover all width between 200px to 767px //
   
    }

For iPad and iPad pro you have to use

  @media only screen and (min-width: 768px) and (max-width: 1024px)  {
        //Put your CSS here for 768px to 1024px width devices(covers all width between 768px to 1024px //   
  }

If you want to add css for Landscape mode you can add this

and (orientation : landscape)

  @media only screen and (min-width: 200px) and (max-width: 767px) and (orientation : portrait) {
        //Put your CSS here for 200px to 767px width devices (cover all mobile portrait width //        
  }

Does m really need to be a data.frame() or will a matrix() suffice?

m <- matrix(0, ncol = 30, nrow = 2)

You can wrap a data.frame() around that if you need to:

m <- data.frame(m)

or all in one line: m <- data.frame(matrix(0, ncol = 30, nrow = 2))

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

Git runs garbage collection automatically:

• If there are too many loose objects in the repository

• When a push to a remote repository happens

• After some commands that might introduce many loose objects

• When some commands such as git reflog expire explicitly request it

And finally, garbage collection occurs when you explicitly request it using the git gc command. But when should that be? There’s no solid answer to this question, but there is some good advice and best practice.

You should consider running git gc manually in a few situations:

• If you have just completed a git filter-branch . Recall that filter-branch rewrites many commits, introduces new ones, and leaves the old ones on a ref that should be removed when you are satisfied with the results. All those dead objects (that are no longer referenced since you just removed the one ref pointing to them) should be removed via garbage collection.

• After some commands that might introduce many loose objects. This might be a large rebase effort, for example.

And on the flip side, when should you be wary of garbage collection?

• If there are orphaned refs that you might want to recover

• In the context of git rerere and you do not need to save the resolutions forever

• In the context of only tags and branches being sufficient to cause Git to retain a commit permanently

• In the context of FETCH_HEAD retrievals (URL-direct retrievals via git fetch ) because they are immediately subject to garbage collection

I feel we may require AND condition in where clause of last figure of Outer Excluding JOIN so that we get the desired result of A Union B Minus A Interaction B. I feel query needs to be updated to

SELECT <select_list>
FROM Table_A A
FULL OUTER JOIN Table_B B
ON A.Key = B.Key
WHERE A.Key IS NULL AND B.Key IS NULL

If we use OR , then we will get all the results of A Union B

Very old question, but for the newcomers: maybe the PowerShell version (similar but not equivalent) that the question is looking for, is to use -and as follows:

(build_command) -and (run_tests_command)

You can have one application listening on one port for one network interface. Therefore you could have:

1. httpd listening on remotely accessible interface, e.g. 192.168.1.1:80
2. another daemon listening on 127.0.0.1:80

Sample use case could be to use httpd as a load balancer or a proxy.

Here's an extension for an in-place occurrences replace method on String, that doesn't no an unnecessary copy and do everything in place:

extension String {
    mutating func replaceOccurrences<Target: StringProtocol, Replacement: StringProtocol>(of target: Target, with replacement: Replacement, options: String.CompareOptions = [], locale: Locale? = nil) {
        var range: Range<Index>?
        repeat {
            range = self.range(of: target, options: options, range: range.map { self.index($0.lowerBound, offsetBy: replacement.count)..<self.endIndex }, locale: locale)
            if let range = range {
                self.replaceSubrange(range, with: replacement)
            }
        } while range != nil
    }
}

(The method signature also mimics the signature of the built-in String.replacingOccurrences() method)

May be used in the following way:

var string = "this is a string"
string.replaceOccurrences(of: " ", with: "_")
print(string) // "this_is_a_string"

I had the same problem even though openssl was enabled. The issue was that the Composer installer was looking at this config file:

C:\wamp\bin\php\php5.4.3\php.ini

But the config file that's loaded is actually here:

C:\wamp\bin\apache\apache2.2.22\bin\php.ini

So I just had to uncomment it in the first php.ini file and that did the trick. This is how WAMP was installed on my machine by default. I didn't go changing anything, so this will probably happen to others as well. This is basically the same as Augie Gardner's answer above, but I just wanted to point out that you might have two php.ini files.

If you need to access those certs programmatically it is best to not use the file at all, but access it via the trust manager. The following code is from a OpenJDK Test case (which makes sure the built cacerts collection is not empty):

TrustManagerFactory trustManagerFactory =
    TrustManagerFactory.getInstance("PKIX");
trustManagerFactory.init((KeyStore) null);
TrustManager[] trustManagers =
    trustManagerFactory.getTrustManagers();
X509TrustManager trustManager =
    (X509TrustManager) trustManagers[0];
X509Certificate[] acceptedIssuers =
    trustManager.getAcceptedIssuers();

So you don’t have to deal with file location or keystore password.

I in no way want to compete with Mark's answer, but just wanted to highlight the piece that finally made everything click as someone new to Javascript inheritance and its prototype chain.

Only property reads search the prototype chain, not writes. So when you set

myObject.prop = '123';

It doesn't look up the chain, but when you set

myObject.myThing.prop = '123';

there's a subtle read going on within that write operation that tries to look up myThing before writing to its prop. So that's why writing to object.properties from the child gets at the parent's objects.

If it is just single column to delete the below syntax works

ALTER TABLE tablename DROP COLUMN column1;

For deleting multiple columns, using the DROP COLUMN doesnot work, the below syntax works

ALTER TABLE tablename DROP (column1, column2, column3......);

I think it depends on what you prefer, as mentioned, theres no general agreement afaik. To reduce annoyment, you may reduce this kind of warning to "Hint"

Here is a sample function: 'df.name = file` : Sixth line in the code below

def df_list(): filename_list = current_stage_files(PATH) df_list = [] for file in filename_list: df = pd.read_csv(PATH+file) df.name = file df_list.append(df) return df_list

i found that in the deployment assembly, there was the entry:

[persisted container] org.maven.ide.eclipse.maven2_classpath_container

i removed it, and added the maven dependencies entry, and it works fine now.

It is a common misconception that time (a measurable 4th dimension) is different over the world. Timestamp as a moment in time is unique. Date however is influenced how we "see" time but actually it is "time of day".

An example: two people look at the clock at the same moment. The timestamp is the same, right? But one of them is in London and sees 12:00 noon (GMT, timezone offset is 0), and the other is in Belgrade and sees 14:00 (CET, Central Europe, daylight saving now, offset is +2).

Their perception is different but the moment is the same.

You can find more details in this answer.

UPDATE

OK, it's not a duplicate of this question but it is pointless since you are confusing the terms "Timestamp = moment in time (objective)" and "Date[Time] = time of day (subjective)".

Let's look at your original question code broken down like this:

// Get the "original" value from database.
Timestamp momentFromDB = rs.getTimestamp("anytimestampcolumn");

// Turn it into a Joda DateTime with time zone.
DateTime dt = new DateTime(momentFromDB, DateTimeZone.forID("anytimezone"));

// And then turn it back into a timestamp but "with time zone".
Timestamp ts = new Timestamp(dt.getMillis());

I haven't run this code but I am certain it will print true and the same number of milliseconds each time:

System.out.println("momentFromDB == dt : " + (momentFromDB.getTime() == dt.getTimeInMillis());
System.out.println("momentFromDB == ts : " + (momentFromDB.getTime() == ts.getTime()));
System.out.println("dt == ts : " + (dt.getTimeInMillis() == ts.getTime()));

System.out.println("momentFromDB [ms] : " + momentFromDB.getTime());
System.out.println("ts [ms] : " + ts.getTime());
System.out.println("dt [ms] : " + dt.getTimeInMillis());

But as you said yourself printing them out as strings will result in "different" time because DateTime applies the time zone. That's why "time" is stored and transferred as Timestamp objects (which basically wraps a long) and displayed or entered as Date[Time].

In your own answer you are artificially adding an offset and creating a "wrong" time. If you use that timestamp to create another DateTime and print it out it will be offset twice.

// Turn it back into a Joda DateTime with time zone.
DateTime dt = new DateTime(ts, DateTimeZone.forID("anytimezone"));

P.S. If you have the time go through the very complex Joda Time source code to see how it holds the time (millis) and how it prints it.

From Unix.SE: A simple command-line utility called gpustat now exists: https://github.com/wookayin/gpustat.

It is free software (MIT license) and is packaged in pypi. It is a wrapper of nvidia-smi.

this is how:

    function get_web_page( $url )
    {
        $user_agent='Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0';

        $options = array(

$page = $result['content'];

bs := string(body) should be enough to give you a string.

From there, you can use it as a regular string.

A bit as in this thread:

var client http.Client
resp, err := client.Get(url)
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()

if resp.StatusCode == http.StatusOK {
    bodyBytes, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        log.Fatal(err)
    }
    bodyString := string(bodyBytes)
    log.Info(bodyString)
}

As commented below (and in zzn's answer), this is a conversion (see spec).
See "How expensive is []byte(string)?" (reverse problem, but the same conclusion apply) where zzzz mentioned:

Some conversions are the same as a cast, like uint(myIntvar), which just reinterprets the bits in place.

Sonia adds:

Making a string out of a byte slice, definitely involves allocating the string on the heap. The immutability property forces this.
Sometimes you can optimize by doing as much work as possible with []byte and then creating a string at the end. The bytes.Buffer type is often useful.

<input type="text" id="inputName"  placeholder="Enter name"  required  oninvalid="this.setCustomValidity('Please Enter your first name')" >

If you are using jQuery, you could scroll with an animation using the following:

$(MyContainerDiv).animate({scrollTop: $(MyContainerDiv).scrollTop() + ($('element_within_div').offset().top - $(MyContainerDiv).offset().top)});

The animation is optional: you could also take the scrollTop value calculated above and put it directly in the container's scrollTop property.

One more point I haven't found anyone mentioned:

If you have virtual method, each declaration can have its own default value!

It depends on the interface you are calling which value will be used.

Example on ideone

struct iface
{
    virtual void test(int a = 0) { std::cout << a; }
};

struct impl : public iface
{
    virtual void test(int a = 5) override { std::cout << a; }
};

int main()
{
    impl d;
    d.test();
    iface* a = &d;
    a->test();
}

It prints 50

I strongly discourage you to use it like this

Use this:

<script type="text/javascript" language="javascript">
    $("#toggle").click(function() { $("#login-form, #recover-password").toggle(); });
</script>

Your HTML should look like:

<a id="toggle" href="javascript:void(0);">forgot password?</a>
<div id="login-form"></div>
<div id="recover-password" style="display:none;"></div>

Hey, all right! One line! I <3 jQuery.

I may be able to help with a list of ticker symbols for (U.S. and non-U.S.) stocks and for ETFs.

Yahoo provides an Earnings Calendar that lists all the stocks that announce earnings for a given day. This includes non-US stocks.

For example, here is today's: http://biz.yahoo.com/research/earncal/20120710.html

the last part of the URL is the date (in YYYYMMDD format) for which you want the Earnings Calendar. You can loop through several days and scrape the Symbols of all stocks that reported earnings on those days.

There is no guarantee that yahoo has data for all stocks that report earnings, especially since some stocks no longer exist (bankruptcy, acquisition, etc.), but this is probably a decent starting point.

If you are familiar with R, you can use the qmao package to do this. (See this post) if you have trouble installing it.

ec <- getEarningsCalendar(from="2011-01-01", to="2012-07-01") #this may take a while
s <- unique(ec$Symbol)
length(s)
#[1] 12223
head(s, 20) #look at the first 20 Symbols
# [1] "CVGW"    "ANGO"    "CAMP"    "LNDC"    "MOS"     "NEOG"    "SONC"   
# [8] "TISI"    "SHLM"    "FDO"     "FC"      "JPST.PK" "RECN"    "RELL"   
#[15] "RT"      "UNF"     "WOR"     "WSCI"    "ZEP"     "AEHR"   

This will not include any ETFs, futures, options, bonds, forex or mutual funds.

You can get a list of ETFs from yahoo here: http://finance.yahoo.com/etf/browser/mkt That only shows the first 20. You need the URL of the "Show All" link at the bottom of that page. You can scrape the page to find out how many ETFs there are, then construct a URL.

L <- readLines("http://finance.yahoo.com/etf/browser/mkt")
# Sorry for the ugly regex
n <- gsub("^(\\w+)\\s?(.*)$", "\\1", 
          gsub("(.*)(Showing 1 - 20 of )(.*)", "\\3",  
               L[grep("Showing 1 - 20", L)]))
URL <- paste0("http://finance.yahoo.com/etf/browser/mkt?c=0&k=5&f=0&o=d&cs=1&ce=", n)
#http://finance.yahoo.com/etf/browser/mkt?c=0&k=5&f=0&o=d&cs=1&ce=1442

Now, you can extract the Tickers from the table on that page

library(XML)
tbl <- readHTMLTable(URL, stringsAsFactors=FALSE)
dat <- tbl[[tail(grep("Ticker", tbl), 1)]][-1, ]
colnames(dat) <- dat[1, ]
dat <- dat[-1, ]
etfs <- dat$Ticker # All ETF tickers from yahoo
length(etfs)
#[1] 1442
head(etfs)
#[1] "DGAZ" "TAGS" "GASX" "KOLD" "DWTI" "RTSA"

That's about all the help I can offer, but you could do something similar to get some of the futures they offer by scraping these pages (These are only U.S. futures)

http://finance.yahoo.com/indices?e=futures, http://finance.yahoo.com/futures?t=energy, http://finance.yahoo.com/futures?t=metals, http://finance.yahoo.com/futures?t=grains, http://finance.yahoo.com/futures?t=livestock, http://finance.yahoo.com/futures?t=softs, http://finance.yahoo.com/futures?t=indices,

And, for U.S. and non-U.S. indices, you could scrape these pages

http://finance.yahoo.com/intlindices?e=americas, http://finance.yahoo.com/intlindices?e=asia, http://finance.yahoo.com/intlindices?e=europe, http://finance.yahoo.com/intlindices?e=africa, http://finance.yahoo.com/indices?e=dow_jones, http://finance.yahoo.com/indices?e=new_york, http://finance.yahoo.com/indices?e=nasdaq, http://finance.yahoo.com/indices?e=sp, http://finance.yahoo.com/indices?e=other, http://finance.yahoo.com/indices?e=treasury, http://finance.yahoo.com/indices?e=commodities

The answer is misleading because it attempts to fix a problem that is not a problem. You actually CAN have a WHERE CLAUSE in each segment of a UNION. You cannot have an ORDER BY except in the last segment. Therefore, this should work...

select top 2 t1.ID, t1.ReceivedDate
from Table t1
where t1.Type = 'TYPE_1'
-----remove this-- order by ReceivedDate desc
union
select top 2 t2.ID,  t2.ReceivedDate --- add second column
  from Table t2
 where t2.Type = 'TYPE_2'
order by ReceivedDate desc

Not related to variables, your example will also be solved by MOD:

=Mod(VLOOKUP(A1, B:B, 1, 0);10)

@CodeReaper, @BennyHill: It works as expected.

However, I wonder the time complexity for having millions of rows in the table? Apparently, it took about 5ms to execute for having 5k records on a correctly indexed table.

My Query:

SET status = '1'
WHERE id IN (
    SELECT id
    FROM (
      SELECT c2.id FROM clusters as c2
      WHERE c2.assign_to_user_id IS NOT NULL
        AND c2.id NOT IN (
         SELECT c1.id FROM clusters AS c1
           LEFT JOIN cluster_flags as cf on c1.last_flag_id = cf.id
           LEFT JOIN flag_types as ft on ft.id = cf.flag_type_id
         WHERE ft.slug = 'closed'
         )
      ) x)```

Or is there something we can improve on my query above?

I prefer to use this extension method:

}

In .NET Core, I managed to get a System.Net.Http.HttpClient with UseDefaultCredentials = true to pass through the authenticated user's Windows credentials to a back end service by using WindowsIdentity.RunImpersonated.

HttpClient client = new HttpClient(new HttpClientHandler { UseDefaultCredentials = true } );
HttpResponseMessage response = null;

if (identity is WindowsIdentity windowsIdentity)
{
    await WindowsIdentity.RunImpersonated(windowsIdentity.AccessToken, async () =>
    {
        var request = new HttpRequestMessage(HttpMethod.Get, url)
        response = await client.SendAsync(request);
    });
}

You can do date arithmetic by using NSDateComponents. For example:

import Foundation

let comps = NSDateComponents()

comps.minute = 5

let cal = NSCalendar.currentCalendar()

let r = cal.dateByAddingComponents(comps, toDate: NSDate(), options: nil)

imgvw .setImageResource();
tv.settext("new text");

Some feedback on the segment of code, though for the most part, it should work...

void main(int c,char **args)

• int main - the standard defines main as returning an int.
• c and args are typically named argc and argv, respectfully, but you are allowed to name them anything

...

{
DIR *dir;
struct dirent *dent;
char buffer[50];
strcpy(buffer,args[1]);

• You have a buffer overflow here: If args[1] is longer than 50 bytes, buffer will not be able to hold it, and you will write to memory that you shouldn't. There's no reason I can see to copy the buffer here, so you can sidestep these issues by just not using strcpy...

...

dir=opendir(buffer);   //this part

If this returning NULL, it can be for a few reasons:

• The directory didn't exist. (Did you type it right? Did it have a space in it, and you typed ./your_program my directory, which will fail, because it tries to opendir("my"))
• You lack permissions to the directory
• There's insufficient memory. (This is unlikely.)

public static void main(String[] args) {
    double g = 1 / 3;
    System.out.printf("%.2f", g);
}

Since both 1 and 3 are ints the result not rounded but it's truncated. So you ignore fractions and take only wholes.

To avoid this have at least one of your numbers 1 or 3 as a decimal form 1.0 and/or 3.0.

According to the documentation of Spring-Cloud-Config there is one extra scope next to the existing five. It is @RefreshScope.

This is the short description of RefreshScope:

When there is a configuration change, a Spring @Bean that is marked as @RefreshScope gets special treatment. This feature addresses the problem of stateful beans that only get their configuration injected when they are initialized. For instance, if a DataSource has open connections when the database URL is changed via the Environment, you probably want the holders of those connections to be able to complete what they are doing. Then, the next time something borrows a connection from the pool, it gets one with the new URL.

Sometimes, it might even be mandatory to apply the @RefreshScope annotation on some beans which can be only initialized once. If a bean is "immutable", you will have to either annotate the bean with @RefreshScope or specify the classname under the property key spring.cloud.refresh.extra-refreshable.

Refresh scope beans are lazy proxies that initialize when they are used (that is, when a method is called), and the scope acts as a cache of initialized values. To force a bean to re-initialize on the next method call, you must invalidate its cache entry.

The RefreshScope is a bean in the context and has a public refreshAll() method to refresh all beans in the scope by clearing the target cache. The /refresh endpoint exposes this functionality (over HTTP or JMX). To refresh an individual bean by name, there is also a refresh(String) method.

Zalgo text works because of combining characters. These are special characters that allow to modify character that comes before.

OR

y + ̆ = y̆ which actually is

y + ̆ = y̆

Since you can stack them one atop the other you can produce the following:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

which actually is:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

The same goes for putting stuff underneath:

y̰̰̰̰̰̰̰̰̰̰̰̰̰̰̰̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

that in fact is:

y̰̰̰̰̰̰̰̰̰̰̰̰̰̰̰̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

In Unicode, the main block of combining diacritics for European languages and the International Phonetic Alphabet is U+0300–U+036F.

More about it here

To produce a list of combining diacritical marks you can use the following script (since links keep on dying)

for(var i=768; i<879; i++){console.log(new DOMParser().parseFromString("&#"+i+";", "text/html").documentElement.textContent +"  "+"&#"+i+";");}

You would simply do this:

SELECT (end_time - start_time) FROM t; -- return in Millisecond
SELECT (end_time - start_time)/1000 FROM t; -- return in Second

There is nothing to fix. You simply have made 3 commits and haven't moved them to the remote branch yet. There are several options, depending on what you want to do:

• git push: move your changes to the remote (this might get rejected if there are already other changes on the remote)
• do nothing and keep coding, sync another day
• git pull: get the changes (if any) from the remote and merge them into your changes
• git pull --rebase: as above, but try to redo your commits on top of the remote changes

You are in a classical situation (although usually you wouldn't commit a lot on master in most workflows). Here is what I would normally do: Review my changes. Maybe do a git rebase --interactive to do some cosmetics on them, drop the ones that suck, reorder them to make them more logical. Now move them to the remote with git push. If this gets rejected because my local branch is not up to date: git pull --rebase to redo my work on top of the most recent changes and git push again.

I am also using nunique but it will be very helpful if you have to use an aggregate function like 'min', 'max', 'count' or 'mean' etc.

df.groupby('YEARMONTH')['CLIENTCODE'].transform('nunique') #count(distinct)
df.groupby('YEARMONTH')['CLIENTCODE'].transform('min')     #min
df.groupby('YEARMONTH')['CLIENTCODE'].transform('max')     #max
df.groupby('YEARMONTH')['CLIENTCODE'].transform('mean')    #average
df.groupby('YEARMONTH')['CLIENTCODE'].transform('count')   #count

Using bash regular expressions:

re="http://([^/]+)/"
if [[ $name =~ $re ]]; then echo ${BASH_REMATCH[1]}; fi

Edit - OP asked for explanation of syntax. Regular expression syntax is a large topic which I can't explain in full here, but I will attempt to explain enough to understand the example.

re="http://([^/]+)/"

This is the regular expression stored in a bash variable, re - i.e. what you want your input string to match, and hopefully extract a substring. Breaking it down:

• http:// is just a string - the input string must contain this substring for the regular expression to match
• [] Normally square brackets are used say "match any character within the brackets". So c[ao]t would match both "cat" and "cot". The ^ character within the [] modifies this to say "match any character except those within the square brackets. So in this case [^/] will match any character apart from "/".
• The square bracket expression will only match one character. Adding a + to the end of it says "match 1 or more of the preceding sub-expression". So [^/]+ matches 1 or more of the set of all characters, excluding "/".
• Putting () parentheses around a subexpression says that you want to save whatever matched that subexpression for later processing. If the language you are using supports this, it will provide some mechanism to retrieve these submatches. For bash, it is the BASH_REMATCH array.
• Finally we do an exact match on "/" to make sure we match all the way to end of the fully qualified domain name and the following "/"

Next, we have to test the input string against the regular expression to see if it matches. We can use a bash conditional to do that:

if [[ $name =~ $re ]]; then
    echo ${BASH_REMATCH[1]}
fi

In bash, the [[ ]] specify an extended conditional test, and may contain the =~ bash regular expression operator. In this case we test whether the input string $name matches the regular expression $re. If it does match, then due to the construction of the regular expression, we are guaranteed that we will have a submatch (from the parentheses ()), and we can access it using the BASH_REMATCH array:

• Element 0 of this array ${BASH_REMATCH[0]} will be the entire string matched by the regular expression, i.e. "http://www.google.com/".
• Subsequent elements of this array will be subsequent results of submatches. Note you can have multiple submatch () within a regular expression - The BASH_REMATCH elements will correspond to these in order. So in this case ${BASH_REMATCH[1]} will contain "www.google.com", which I think is the string you want.

Note that the contents of the BASH_REMATCH array only apply to the last time the regular expression =~ operator was used. So if you go on to do more regular expression matches, you must save the contents you need from this array each time.

This may seem like a lengthy description, but I have really glossed over several of the intricacies of regular expressions. They can be quite powerful, and I believe with decent performance, but the regular expression syntax is complex. Also regular expression implementations vary, so different languages will support different features and may have subtle differences in syntax. In particular escaping of characters within a regular expression can be a thorny issue, especially when those characters would have an otherwise different meaning in the given language.

Note that instead of setting the $re variable on a separate line and referring to this variable in the condition, you can put the regular expression directly into the condition. However in bash 3.2, the rules were changed regarding whether quotes around such literal regular expressions are required or not. Putting the regular expression in a separate variable is a straightforward way around this, so that the condition works as expected in all bash versions that support the =~ match operator.

First 10 customers inserted into db (table customers):

select * from customers where customer_id <=
(select  min(customer_id)+10 from customers)

Last 10 customers inserted into db (table customers):

select * from customers where customer_id >=
(select  max(customer_id)-10 from customers)

Hope this helps....

It's not entirely clear if you mean you want to find the process who has most pages swapped out or process who caused most pages to be swapped out.

For the first you may run top and order by swap (press 'Op'), for the latter you can run vmstat and look for non-zero entries for 'so'.

select group_id, 
       listagg(name, ',') within group (order by name) as names
       over (partition by group_id)

group by group_id 

The percent symbol means: any host, including remote and local connections.

The localhost allows only local connections.

(so to start off, if you don't need remote connections to your database, you can get rid of the appuser@'%' user right away)

So, yes, they are overlapping, but...

...there is a reason for setting both types of accounts, this is explained in the mysql docs: http://dev.mysql.com/doc/refman/5.7/en/adding-users.html.

If you have an have an anonymous user on your localhost, which you can spot with:

select Host from mysql.user where User='' and Host='localhost';

and if you just create the user appuser@'%' (and you not the appuser@'localhost'), then when the appuser mysql user connects from the local host, the anonymous user account is used (it has precedence over your appuser@'%' user).

And the fix for this is (as one can guess) to create the appuser@'localhost' (which is more specific that the local host anonymous user and will be used if your appuser connects from the localhost).

You escape ' by doubling it, so:

Select * from tblStudents where name like 'Daniel O''Neal' 

Note that if you're accepting "Daniel O'Neal" from user input, the broken quotation is a serious security issue. You should always sanitize the string or use parametrized queries.

Instead of setBackgroundColor, retrieve the background drawable and set its color:

v.setBackgroundResource(R.drawable.tags_rounded_corners);

GradientDrawable drawable = (GradientDrawable) v.getBackground();
if (i % 2 == 0) {
  drawable.setColor(Color.RED);
} else {
  drawable.setColor(Color.BLUE);
}

Also, you can define the padding within your tags_rounded_corners.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
  <corners android:radius="4dp" />
  <padding
    android:top="2dp"
    android:left="2dp"
    android:bottom="2dp"
    android:right="2dp" />
</shape>

error: The branch 'guided-furniture' is not fully merged.
If you are sure you want to delete it, run 'git branch -D guided-furniture'.

The solution for me was simply that the feature branch needed to be pushed up to the remote. Then when I ran:

git push origin guided-furniture
/* You might need to fetch here */
git branch -d guided-furniture

Deleted branch guided-furniture (was 1813496).

    //your code goes here on location change 
});

By using javascript:

window.addEventListener("beforeunload", function (event) {
   //your code goes here on location change 
});

Refer Document : https://developer.mozilla.org/en-US/docs/Web/Events/beforeunload

For Android 4.2 (API 17), you need to use android:configChanges="locale|layoutDirection" in your AndroidManifest.xml. See onConfigurationchanged is not called over jellybean(4.2.1)

Alternative way (but it's not python style. It's JS style)

{{ files and 'Update' or 'Continue' }}
