If you are trying to get extra data in fragments then you can try using:

Place data using:

Bundle args = new Bundle();
args.putInt(DummySectionFragment.ARG_SECTION_NUMBER);

Get data using:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {


  getArguments().getInt(ARG_SECTION_NUMBER);
  getArguments().getString(ARG_SECTION_STRING);
  getArguments().getBoolean(ARG_SECTION_BOOL);
  getArguments().getChar(ARG_SECTION_CHAR);
  getArguments().getByte(ARG_SECTION_DATA);

}

I believe this is what you're looking for:

var press = jQuery.Event("keypress");
press.ctrlKey = false;
press.which = 40;
$("whatever").trigger(press);

From here.

Using @property and @dynamic could also work. If you declare a dynamic property and don't give a matching method implementation, everything will still compile without warnings, and you'll get an unrecognized selector error at runtime if you try to access it. This essentially the same thing as calling [self doesNotRecognizeSelector:_cmd], but with far less typing.

Expanding on retrography's answer..: I had this same problem even when using LocalDate and not LocalDateTime. The issue was that I had created my DateTimeFormatter using .withResolverStyle(ResolverStyle.STRICT);, so I had to use date pattern uuuuMMdd instead of yyyyMMdd (i.e. "year" instead of "year-of-era")!

DateTimeFormatter formatter = new DateTimeFormatterBuilder()
  .parseStrict()
  .appendPattern("uuuuMMdd")
  .toFormatter()
  .withResolverStyle(ResolverStyle.STRICT);
LocalDate dt = LocalDate.parse("20140218", formatter);

(This solution was originally a comment to retrography's answer, but I was encouraged to post it as a stand-alone answer because it apparently works really well for many people.)

This can now be done as of docker-compose v2+ as part of the build object;

docker-compose.yml

version: '2'
services:
    my_image_name:
        build:
            context: . #current dir as build context
            args:
                var1: 1
                var2: c

See the docker compose docs.

In the above example "var1" and "var2" will be sent to the build environment.

Note: any env variables (specified by using the environment block) which have the same name as args variable(s) will override that variable.

display: inline; is a display mode to use in a sentence. For instance, if you have a paragraph and want to highlight a single word you do:

<p>
    Pellentesque habitant morbi <em>tristique</em> senectus
    et netus et malesuada fames ac turpis egestas.
</p>

The <em> element has a display: inline; by default, because this tag is always used in a sentence. The <p> element has a display: block; by default, because it's neither a sentence nor in a sentence, it's a block of sentences.

An element with display: inline; cannot have a height or a width or a vertical margin. An element with display: block; can have a width, height and margin.
If you want to add a height to the <em> element, you need to set this element to display: inline-block;. Now you can add a height to the element and every other block style (the block part of inline-block), but it is placed in a sentence (the inline part of inline-block).

First of all, two things that we need to understand,

Client

• It makes request to a specific server

bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);

here mServiceConn is instance of ServiceConnection class(inbuilt) it is actually interface that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.

Server

• It handles the request of the client and makes replica of its own which is private to client only who send request and this raplica of server runs on different thread.

Now at client side, how to access all the methods of server?

• Server sends response with IBinder Object. So, IBinder object is our handler which accesses all the methods of Service by using (.) operator.

.

MyService myService;
public ServiceConnection myConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder binder) {
        Log.d("ServiceConnection","connected");
        myService = binder;
    }
    //binder comes from server to communicate with method's of 

    public void onServiceDisconnected(ComponentName className) {
        Log.d("ServiceConnection","disconnected");
        myService = null;
    }
}

Now how to call method which lies in service

myservice.serviceMethod();

Here myService is object and serviceMethod is method in service. and by this way communication is established between client and server.

Swift 2.0 solution:

You need to go into your Attribute Inspector and add a name for your cells Identifier:

Then you need to make your identifier match with your dequeue like this:

let cell2 = tableView.dequeueReusableCellWithIdentifier("ButtonCell", forIndexPath: indexPath) as! ButtonCell

Alternatively

If you're working with a nib you may need to register your class in your cellForRowAtIndexPath:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {       

    tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "SwitchCell")

    // included for context            
    let cell = tableView.dequeueReusableCellWithIdentifier("SwitchCell", forIndexPath:indexPath) as! SwitchCell

    //... continue    
}

Apples's UITableView Class Reference says:

Prior to dequeueing any cells, call this method or the registerNib:forCellReuseIdentifier: method to tell the table view how to create new cells. If a cell of the specified type is not currently in a reuse queue, the table view uses the provided information to create a new cell object automatically.

If you previously registered a class or nib file with the same reuse identifier, the class you specify in the cellClass parameter replaces the old entry. You may specify nil for cellClass if you want to unregister the class from the specified reuse identifier.

Here's the code from Apples Swift 2.0 framework:

// Beginning in iOS 6, clients can register a nib or class for each cell.
// If all reuse identifiers are registered, use the newer -dequeueReusableCellWithIdentifier:forIndexPath: to guarantee that a cell instance is returned.
// Instances returned from the new dequeue method will also be properly sized when they are returned.

@available(iOS 5.0, *)
func registerNib(nib: UINib?, forCellReuseIdentifier identifier: String)

@available(iOS 6.0, *)
func registerClass(cellClass: AnyClass?, forCellReuseIdentifier identifier: String)

Generally, setting static field by object instance is a bad practice.

to avoid optional issues you can add synchronized definition, and set it only if private static Logger logger;

@Autowired
public synchronized void setLogger(Logger logger)
{
    if (MyClass.logger == null)
    {
        MyClass.logger = logger;
    }
}

:

1) Are you sure mod_rewrite module is enabled? Check phpinfo()

2) Your above rule assumes the URL starts with "folder". Is this correct? Did you acutally want to have folder in the URL? This would match a URL like:

/folder/thing -> /folder/thing.php

If you actually want

/thing -> /folder/thing.php

You need to drop the folder from the match expression.

I usually use this to route request to page without php (but yours should work which leads me to think that mod_rewrite may not be enabled):

RewriteRule ^([^/\.]+)/?$ $1.php  [L,QSA]

3) Assuming you are declaring your rules in an .htaccess file, does your installation allow for setting Options (AllowOverride) overrides in .htaccess files? Some shared hosts do not.

When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information.

if the system you use is CentOS/RedHat, and rpm is the way you install MySQL, there is no my.cnf in /etc/ folder, you could use: #whereis mysql #cd /usr/share/mysql/ cp -f /usr/share/mysql/my-medium.cnf /etc/my.cnf

Found similar problem within student's work, script element was put after closing body tag, so, obviously, JavaScript could not find any HTML element.

But, there was one more serious error: there was a reference to an external javascript file with some code, which removed all contents of a certain HTML element before inserting new content. After commenting out this reference, everything worked properly.

So, sometimes the error might be that some previously called Javascript changed content or even DOM, so calling for instance getElementById later doesn't make sense, since that element was removed.

The same way you make anything else negative: put a negative sign in front of it.

var positive = 6;
var negative = -positive;

Generic Webhook Trigger Plugin can be configured with filters to achieve this.

When configured with

• A variable named ref and expression $.ref.
• A filter with text $ref and filter expression like ^refs/heads/master$.

Then that job will trigger for every push to master. No polling.

You probably want more values from the webhook to actually perform the build. Just add more variables, with JSONPath, to pick what you need.

There are some use cases here: https://github.com/jenkinsci/generic-webhook-trigger-plugin/tree/master/src/test/resources/org/jenkinsci/plugins/gwt/bdd

Using PuTTY's pscp.exe (which I have in an $env:path directory):

pscp -sftp -pw passwd c:\filedump\* user@host:/Outbox/
mv c:\filedump\* c:\backup\*

I have a very similar problem. Actually the problem is deeper as I thought. I am using jquery $.post which uses Content-Type:application/x-www-form-urlencoded; charset=UTF-8 as default. Unfortunately I based my system on that and when I needed a complex object as a @RequestParam I couldn't just make it happen.

In my case I am trying to send user preferences with something like;

 $.post("/updatePreferences",  
    {id: 'pr', preferences: p}, 
    function (response) {
 ...

On client side the actual raw data sent to the server is;

...
id=pr&preferences%5BuserId%5D=1005012365&preferences%5Baudio%5D=false&preferences%5Btooltip%5D=true&preferences%5Blanguage%5D=en
...

parsed as;

id:pr
preferences[userId]:1005012365
preferences[audio]:false
preferences[tooltip]:true
preferences[language]:en

and the server side is;

@RequestMapping(value = "/updatePreferences")
public
@ResponseBody
Object updatePreferences(@RequestParam("id") String id, @RequestParam("preferences") UserPreferences preferences) {

    ...
        return someService.call(preferences);
    ...
}

I tried @ModelAttribute, added setter/getters, constructors with all possibilities to UserPreferences but no chance as it recognized the sent data as 5 parameters but in fact the mapped method has only 2 parameters. I also tried Biju's solution however what happens is that, spring creates an UserPreferences object with default constructor and doesn't fill in the data.

I solved the problem by sending JSon string of the preferences from the client side and handle it as if it is a String on the server side;

client:

 $.post("/updatePreferences",  
    {id: 'pr', preferences: JSON.stringify(p)}, 
    function (response) {
 ...

server:

@RequestMapping(value = "/updatePreferences")
public
@ResponseBody
Object updatePreferences(@RequestParam("id") String id, @RequestParam("preferences") String preferencesJSon) {


        String ret = null;
        ObjectMapper mapper = new ObjectMapper();
        try {
            UserPreferences userPreferences = mapper.readValue(preferencesJSon, UserPreferences.class);
            return someService.call(userPreferences);
        } catch (IOException e) {
            e.printStackTrace();
        }
}

to brief, I did the conversion manually inside the REST method. In my opinion the reason why spring doesn't recognize the sent data is the content-type.

In your Manifest file write this before </application >

<activity android:name="com.fsck.k9.activity.MessageList">
   <intent-filter>
      <action android:name="android.intent.action.MAIN">
      </action>
   </intent-filter>
</activity>

and tell me if it solves your issue :)

Add the frameBorder attribute (note the capital ‘B’).

So it would look like:

<iframe src="myURL" width="300" height="300" frameBorder="0">Browser not compatible.</iframe>

class foo(object):
    def __str__(self):
        return "representation"
    def __unicode__(self):
        return u"representation"

Flexbox is a modern alternative that lets you do this without fixed heights or JavaScript.

Setting display: flex; flex-direction: column; on the container and flex-shrink: 0; on the header and footer divs does the trick:

CSS:

#body {
    position: absolute;
    top: 150px;
    left: 150px;
    height: 300px;
    width: 500px;
    border: black dashed 2px;
    display: flex;
    flex-direction: column;
}

#head {
    border: green solid 1px;
    flex-shrink: 0;
}

#content{
    border: red solid 1px;
    overflow-y: auto;
    /*height: 100%;*/
}

#foot {
    border: blue solid 1px;
    height: 50px;
    flex-shrink: 0;
}

I know the difference between a declaration and a definition.

Whereas:

• A CPP file includes the definitions from any header which it includes (because CPP and header file together become a single 'translation unit')
• A header file might be included by more than one CPP file
• The linker typically won't like anything defined in more than one CPP file

Therefore any definitions in a header file should be inline or static. Header files also contain declarations which are used by more than one CPP file.

Definitions that are neither static nor inline are placed in CPP files. Also, any declarations that are only needed within one CPP file are often placed within that CPP file itself, nstead of in any (sharable) header file.

As an update to Scott Munro's answer:

• In C# 6.0 and VB.NET 14.0 (VS 2015), either Environment.ExitCode or Environment.Exit(exitCode) is required to return an non-zero code from a console application. Changing the return type of Main has no effect.
• In F# 4.0 (VS 2015), the return value of the main entry point is respected.

Try this:

function btnClick() {
    var x = document.getElementById("mytable").getElementsByTagName("td");
    x[0].innerHTML = "i want to change my cell color";
    x[0].style.backgroundColor = "yellow";            
}

Set from JS, backgroundColor is the equivalent of background-color in your style-sheet.

Note also that the .cells collection belongs to a table row, not to the table itself. To get all the cells from all rows you can instead use getElementsByTagName().

This can be done elegantly with Ray, a system that allows you to easily parallelize and distribute your Python code.

To parallelize your example, you'd need to define your functions with the @ray.remote decorator, and then invoke them with .remote.

import ray

ray.init()

dir1 = 'C:\\folder1'
dir2 = 'C:\\folder2'
filename = 'test.txt'
addFiles = [25, 5, 15, 35, 45, 25, 5, 15, 35, 45]

# Define the functions. 
# You need to pass every global variable used by the function as an argument.
# This is needed because each remote function runs in a different process,
# and thus it does not have access to the global variables defined in 
# the current process.
@ray.remote
def func1(filename, addFiles, dir):
    # func1() code here...

@ray.remote
def func2(filename, addFiles, dir):
    # func2() code here...

# Start two tasks in the background and wait for them to finish.
ray.get([func1.remote(filename, addFiles, dir1), func2.remote(filename, addFiles, dir2)]) 

If you pass the same argument to both functions and the argument is large, a more efficient way to do this is using ray.put(). This avoids the large argument to be serialized twice and to create two memory copies of it:

largeData_id = ray.put(largeData)

ray.get([func1(largeData_id), func2(largeData_id)])

Important - If func1() and func2() return results, you need to rewrite the code as follows:

ret_id1 = func1.remote(filename, addFiles, dir1)
ret_id2 = func2.remote(filename, addFiles, dir2)
ret1, ret2 = ray.get([ret_id1, ret_id2])

There are a number of advantages of using Ray over the multiprocessing module. In particular, the same code will run on a single machine as well as on a cluster of machines. For more advantages of Ray see this related post.

Since your top level view already has android:background property set, you can use a <layer-list> (link) to create a new XML drawable that combines both your old background and your new rounded corners background.

Each <item> element in the list is drawn over the next, so the last item in the list is the one that ends up on top.

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <bitmap android:src="@drawable/mydialogbox" />
    </item>
    <item>
        <shape>
            <stroke
                android:width="1dp"
                android:color="@color/common_border_color" />

            <solid android:color="#ffffff" />

            <padding
                    android:left="1dp"
                    android:right="1dp"
                    android:top="1dp" />

            <corners android:radius="5dp" />
        </shape>
    </item>
</layer-list>

To change the labels for Pandas df.plot() use ax.legend([...]):

import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
df.plot(kind='bar', ax=ax)
#ax = df.plot(kind='bar') # "same" as above
ax.legend(["AAA", "BBB"]);

Another approach is to do the same by plt.legend([...]):

import matplotlib.pyplot as plt
df.plot(kind='bar')
plt.legend(["AAA", "BBB"]);

We can get official code From the internet! Refer this:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trim

Running the following code before any other code will create trim() if it's not natively available.

if (!String.prototype.trim) {
  (function() {
    // Make sure we trim BOM and NBSP
    var rtrim = /^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g;
    String.prototype.trim = function() {
      return this.replace(rtrim, '');
    };
  })();
}

for more: I just found there is js project for supporting EcmaScript 5: https://github.com/es-shims/es5-shim by reading the source code, we can get more knowledge about trim.

In Excel 2007, goto Insert/Shape and pick a shape. Colour it and enter whatever text you want. Then right click on the shape and insert a hyperlink

A few tips with shapes..

If you want to easily position the shape with cells, hold down Alt when you move the shape and it will lock to the cell. If you don't want the shape to move or resize with rows/columns, right click the shape, select size and properties and choose the setting which works best.

Thanks, Manish Kumar

There is no single function that does what you want. Your definition of shift is slightly different than what most people are doing. The ways to shift an array are more commonly looped:

>>>xs=np.array([1,2,3,4,5])
>>>shift(xs,3)
array([3,4,5,1,2])

However, you can do what you want with two functions.
Consider a=np.array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.]):

def shift2(arr,num):
    arr=np.roll(arr,num)
    if num<0:
         np.put(arr,range(len(arr)+num,len(arr)),np.nan)
    elif num > 0:
         np.put(arr,range(num),np.nan)
    return arr
>>>shift2(a,3)
[ nan  nan  nan   0.   1.   2.   3.   4.   5.   6.]
>>>shift2(a,-3)
[  3.   4.   5.   6.   7.   8.   9.  nan  nan  nan]

After running cProfile on your given function and the above code you provided, I found that the code you provided makes 42 function calls while shift2 made 14 calls when arr is positive and 16 when it is negative. I will be experimenting with timing to see how each performs with real data.

Try this very simple:

            var cookieExist = $.cookie("status");
            if(cookieExist == "null" ){
                alert("Cookie Is Null");

            }

String phoneNumberstr = "Tel: 00971-557890-999";
String numberRefined = phoneNumberstr.replaceAll("[^\\d-]", "");

result: 0097-557890-999

if you also do not need "-" in String you can do like this:

String phoneNumberstr = "Tel: 00971-55 7890 999";      
String numberRefined = phoneNumberstr.replaceAll("[^0-9]", "");

result: 0097557890999

You can use << to append to a string in-place.

s = "foo"
old_id = s.object_id
s << "bar"
s                      #=> "foobar"
s.object_id == old_id  #=> true

Simple solution for this problem is :

Click on the switch and then press CTL+1, It will change your switch to if-else block statement, and will resolve your problem

Because you're using Python 3.1, you need to use the new Python 3.1 APIs.

Try:

urllib.request.urlopen('http://www.python.org/')

Alternately, it looks like you're working from Python 2 examples. Write it in Python 2, then use the 2to3 tool to convert it. On Windows, 2to3.py is in \python31\tools\scripts. Can someone else point out where to find 2to3.py on other platforms?

Edit

These days, I write Python 2 and 3 compatible code by using six.

from six.moves import urllib
urllib.request.urlopen('http://www.python.org')

Assuming you have six installed, that runs on both Python 2 and Python 3.

I was having a similar problem that I could not resolve for a long time on my new server. In addition to palacsint's answer, a good question to ask is: are you using Apache 2.4? In Apache 2.4 there is a different mechanism for setting the permissions that do not work when done using the above configuration, so I used the solution explained in this blog post.

Basically, what I needed to do was convert my config file from:

Alias /demo /usr/demo/html

<Directory "/usr/demo/html">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    allow from all

</Directory>

to:

Alias /demo /usr/demo/html

<Directory "/usr/demo/html">
    Options FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

Note how the Order and allow lines have been replaced by Require all granted

This will display the selected values:

<?php

    if ($_POST) { 
        foreach($_POST['select2'] as $selected) {
            echo $selected."<br>";
        }
    }

?>

I know this question is ancient and has an accepted answer, but I found a better solution to the problem. I am posting it here so I don't create a duplicate question, and the solution is still available to others.

Switch the order of the elements. Use the :before pseudo-element for the content that should be underneath, and adjust margins to compensate. The margin cleanup can be messy, but the desired z-index will be preserved.

I've tested this with IE8 and FF3.6 successfully.

Below mechanism helps in redirecting multiple lines to file. Keep complete string under " so that we can redirect values of the variable.

#!/bin/bash
kernel="2.6.39"
echo "line 1, ${kernel}
line 2," > a.txt
echo 'line 2, ${kernel}
line 2,' > b.txt

Content of a.txt is

line 1, 2.6.39
line 2,

Content of b.txt is

line 2, ${kernel}
line 2,

F12 is easier than Ctrl+Shift+I

As from MSDN for GetChanges

A filtered copy of the DataTable that can have actions performed on it, and later be merged back in the DataTable using Merge. If no rows of the desired DataRowState are found, the method returns Nothing (null).

dataTable1 is null so just check before you iterate over it.

I solved this by doing the following:

<body class="container-fluid">
    <div class="row">
        <div class="span6" style="float: none; margin: 0 auto;">
           ....
        </div>
    </div>
</body>

Using jQuery:

$('#gift-close').click();

=SORT(UNIQUE(A:A))

The above formula works best if you want to list unique values in a column.

It is called an array initializer and can be explained in the Java specification 10.6.

This can be used to initialize any array, but it can only be used for initialization (not assignment to an existing array). One of the unique things about it is that the dimensions of the array can be determined from the initializer. Other methods of creating an array require you to manually insert the number. In many cases, this helps minimize trivial errors which occur when a programmer modifies the initializer and fails to update the dimensions.

Basically, the initializer allocates a correctly sized array, then goes from left to right evaluating each element in the list. The specification also states that if the element type is an array (such as it is for your case... we have an array of double[]), that each element may, itself be an initializer list, which is why you see one outer set of braces, and each line has inner braces.

Alternatively, you can just use position:absolute:

#content
{
    position:absolute;
    top: 111px;
    bottom: 0px;
}

However, IE6 doesn't like top and bottom declarations. But web developers don't like IE6.

While we submit spark jobs using spark-submit utility, there is an option --jars . Using this option, we can pass jar file to spark applications.

Just want to mention another option here.

You can compute the coefficients using numpy.polyfit(), and feed the coefficients to numpy.poly1d(). This function can construct polynomials using the coefficients, you can find more examples here

https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.poly1d.html

Let's say, given two data points (-0.3, -0.5) and (0.8, 0.8)

import numpy as np
import matplotlib.pyplot as plt

# compute coefficients
coefficients = np.polyfit([-0.3, 0.8], [-0.5, 0.8], 1) 

# create a polynomial object with the coefficients
polynomial = np.poly1d(coefficients)

# for the line to extend beyond the two points, 
# create the linespace using the min and max of the x_lim
# I'm using -1 and 1 here
x_axis = np.linspace(-1, 1)

# compute the y for each x using the polynomial
y_axis = polynomial(x_axis)

fig = plt.figure()
axes = fig.add_axes([0.1, 0.1, 1, 1])
axes.set_xlim(-1, 1)
axes.set_ylim(-1, 1)
axes.plot(x_axis, y_axis)
axes.plot(-0.3, -0.5, 0.8, 0.8, marker='o', color='red')

Hope it helps.

Use a semicolon

OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";

REMEMBER, this method overwrites first array, so use only when you are sure!

$arr1 = $arr1 + $arr2;

(see source)

In your code behind file, have a public variable

public partial class _Default : System.Web.UI.Page
{
    public string clients;

    protected void Page_Load(object sender, EventArgs e)
    {
        // your code that at one points sets the variable
        this.clients = "abc";
    }
}

now in your design code, just assign that to something, like:

<div>
    <p><%= clients %></p>
</div>

or even a javascript variable

<script type="text/javascript">

    var clients = '<%= clients %>';

</script>

The DictWriter() class expects dictionaries for each row. If all you wanted to do was write an initial header, use a regular csv.writer() and pass in a simple row for the header:

import csv

with open('combined_file.csv', 'w', newline='') as outcsv:
    writer = csv.writer(outcsv)
    writer.writerow(["Date", "temperature 1", "Temperature 2"])

    with open('t1.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows(row + [0.0] for row in reader)

    with open('t2.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows(row[:1] + [0.0] + row[1:] for row in reader)

The alternative would be to generate dictionaries when copying across your data:

import csv

with open('combined_file.csv', 'w', newline='') as outcsv:
    writer = csv.DictWriter(outcsv, fieldnames = ["Date", "temperature 1", "Temperature 2"])
    writer.writeheader()

    with open('t1.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows({'Date': row[0], 'temperature 1': row[1], 'temperature 2': 0.0} for row in reader)

    with open('t2.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows({'Date': row[0], 'temperature 1': 0.0, 'temperature 2': row[1]} for row in reader)

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:

final float FACTOR  = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);

That should do the trick without casting.

You have two options, a PL/SQL block or SQL*Plus bind variables:

var z number

execute  my_stored_proc (-1,2,0.01,:z)

print z

According to my perspective, the main difference between script and program:

Scripts can be used with the other technologies. Example: PHP scripts, Javascripts, etc. can be used within HTML.

Programs are stand-alone chunks of code that can never be embedded into the other technologies.

If I am wrong at any place please correct me.I will admire your correction.

refs is not a DOM element. In order to find a DOM element, you need to use findDOMNode menthod first.

Do, this

var node = ReactDOM.findDOMNode(this.refs.btn);
node.classList.toggle('btn-menu-open');

alternatively, you can use like this (almost actual code)

this.state.styleCondition = false;


<a ref="btn" href="#" className={styleCondition ? "btn-menu show-on-small" : ""}><i></i></a>

you can then change styleCondition based on your state change conditions.

Specify the property in filter, of object on which you want to apply filter:

//Suppose Object
var users = [{
  "firstname": "XYZ",
  "lastname": "ABC",
  "Address": "HOUSE NO-1, Example Street, Example Town"
},
{
  "firstname": "QWE",
  "lastname": "YUIKJH",
  "Address": "HOUSE NO-11, Example Street1, Example Town1"
}]

But you want to apply filter only on firstname

<input type = "text" ng-model = "first_name_model"/>
<div ng-repeat="user in users| filter:{ firstname: first_name_model}">

Just add this method to the base class

public abstract class clsAbstractTable {

    public abstract String getTAG();
    public abstract void init();

}

Now every class that extends the base class (and does not want to be abstract) should provide a TAG

You could also go with BalusC's answer

I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.

Add .* to s in your first line.

Try:

DELETE s.* FROM spawnlist s
INNER JOIN npc n ON s.npc_templateid = n.idTemplate
WHERE (n.type = "monster");

Try this query:

SELECT *
FROM table 
WHERE MONTH(FROM_UNIXTIME(columnName))= MONTH(CURDATE())

This is an extremely broad subject. Basically, you can't really recover from memory corruption, but you can at least try to fail promptly. Here are a few techniques you could use:

• checksum constant data. If you have any configuration data which stays constant for a long time (including hardware registers you have configured), compute its checksum on initialization and verify it periodically. When you see a mismatch, it's time to re-initialize or reset.

• store variables with redundancy. If you have an important variable x, write its value in x1, x2 and x3 and read it as (x1 == x2) ? x2 : x3.

• implement program flow monitoring. XOR a global flag with a unique value in important functions/branches called from the main loop. Running the program in a radiation-free environment with near-100% test coverage should give you the list of acceptable values of the flag at the end of the cycle. Reset if you see deviations.

• monitor the stack pointer. In the beginning of the main loop, compare the stack pointer with its expected value. Reset on deviation.

SELECT VARCHAR_FORMAT(CURRENT TIMESTAMP, 'YYYYMMDD')
FROM SYSIBM.SYSDUMMY1

Should work on both Mainframe and Linux/Unix/Windows DB2. Info Center entry for VARCHAR_FORMAT().

df.index

• outputs the row names as pandas Index object.

list(df.index)

• casts to a list.

df.index['Row 2':'Row 5']

• supports label slicing similar to columns.

As described by the link I've given in comment, this

$('p[MyTag]').each(function(index) {
  document.write(index + ': ' + $(this).text() + "<br>");});

works (playable example).

If you want to suppress this warning in elegant way (because you are sure that accessibility is not needed for this particular ImageView), you can use special attribute:

android:importantForAccessibility="no"

It depends if you consider if a subclass of a given class is equals to its parent.

class LastName
{
(...)
}


class FamilyName
extends LastName
{
(..)
}

here I would use 'instanceof', because I want a LastName to be compared to FamilyName

class Organism
{
}

class Gorilla extends Organism
{
}

here I would use 'getClass', because the class already says that the two instances are not equivalent.

Have you got org.springframework.orm.hibernate3.support.OpenSessionInViewFilter configured in webapp's web.xml (assuming your application is a webapp), or wrapping calls accordingly?

I had everything set up, but still couldn't see proper error pages for status code 500 on our staging server, despite the fact everything worked fine on local development servers.

I found this blog post from Rick Strahl that helped me.

I needed to add Response.TrySkipIisCustomErrors = true; to my custom error handling code.

You can use getActivity().getSupportFragmentManager() anytime you want to getSupportFragmentManager.

hierarchy is Activity -> fragment. fragment is not capable of directly calling getSupportFragmentManger but Activity can . Thus, you can use getActivity to call the current activity which the fragment is in and get getSupportFragmentManager()

There is some overhead with reflection, but it's a lot smaller on modern VMs than it used to be.

If you're using reflection to create every simple object in your program then something is wrong. Using it occasionally, when you have good reason, shouldn't be a problem at all.

I figured out Leafpad to be an adequate and simple text-editor to view and save/convert in certain character sets - at least in the linux-world.

I used this to save the Latin-15 to UTF-8 and it worked.

Here is another place where I like to use this pattern:

 while data in items:
     try
        data = json.loads(data)
     except ValueError as e:
        log error
     else:
        # work on the `data`

Here is an ES6 version

const repeat = (a,n) => Array(n).join(a+"|$|").split("|$|");_x000D_
repeat("A",20).forEach((a,b) => console.log(a,b+1))

Simple plot,

you can use:

df.plot(x='Date',y='adj_close')

Or you can set the index to be Date beforehand, then it's easy to plot the column you want:

df.set_index('Date', inplace=True)
df['adj_close'].plot()

If you want a chart with one series by ticker on it

You need to groupby before:

df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)

If you want a chart with individual subplots:

grouped = df.groupby('ticker')

ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))

fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)

for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
    grouped.get_group(key).plot(ax=ax)

ax.legend()
plt.show()

Change the "default" Python by putting it ahead of the system Python on your path, for instance:

export PATH=/usr/local/bin:$PATH

• The simple question to your answer is already answered a lot of times:

  /*
  LINES I WANT COMMENTED
  LINES I WANT COMMENTED
  LINES I WANT COMMENTED
  */
  

• From your question it sounds like you want to comment out a lot of code?? I would advise to use a repository(git/github) to manage your files instead of commenting out lines.

• My last advice would be to learn about javadoc if not already familiar because documenting your code is really important.

Building on @P-Lapointe solution, but making it extremely easy, you could use the maximum values from your data using max() and then you re-use those maximum values to set the legend xy coordinates. To make sure you don't get beyond the borders, you set up ylim slightly over the maximum values.

a=c(rnorm(1000))
b=c(rnorm(1000))
par(mfrow=c(1,2))
plot(a,ylim=c(0,max(a)+1))
legend(x=max(a)+0.5,legend="a",pch=1)
plot(a,b,ylim=c(0,max(b)+1),pch=2)
legend(x=max(b)-1.5,y=max(b)+1,legend="b",pch=2)

They both increment the number. ++i is equivalent to i = i + 1.

i++ and ++i are very similar but not exactly the same. Both increment the number, but ++i increments the number before the current expression is evaluted, whereas i++ increments the number after the expression is evaluated.

int i = 3;
int a = i++; // a = 3, i = 4
int b = ++a; // b = 4, a = 4

This addresses the different question, how to get images in gist (as opposed to github) markdown in the first place ?

1. Make a gist, say Mygist.md (and optionally more files)
2. Go to the "Write Comment" box at the end
3. Click "Attach files ... by selecting them"; select your local image file
4. GitHub echos a long long string where it put the image, e.g. 
5. Cut-paste that by hand into your Mygist.md.

But: GitHub people may change this behavior tomorrow, without documenting it.

First we can just run map() function to get the new array with the results of calling a provided function on every element in the varjson.DATA.

varjson.DATA.map(({name})=>name))

After getting the array of name from the varjson.DATA. We can convert it into a set that will discard all duplicate entries of array and apply spread operator to get a array of unique names:

[...new Set(varjson.DATA.map(({name})=>name))]

const varjson = {_x000D_

There's a nice article here which discusses this point. Key things to take away are that there is no difference in table size, however some users prefer to use an empty string as it can make queries easier as there is not a NULL check to do. You just check if the string is empty. Another thing to note is what NULL means in the context of a relational database. It means that the pointer to the character field is set to 0x00 in the row's header, therefore no data to access.

Update There's a detailed article here which talks about what is actually happening on a row basis

Each row has a null bitmap for columns that allow nulls. If the row in that column is null then a bit in the bitmap is 1 else it's 0.

For variable size datatypes the acctual size is 0 bytes.

For fixed size datatype the acctual size is the default datatype size in bytes set to default value (0 for numbers, '' for chars).

the result of DBCC PAGE shows that both NULL and empty strings both take up zero bytes.

I agree with the Hamed elahi and Glorfindel.

My suggestion to add is you can delete and update using aliases

/* 
  given a table bi_customer_actions
  with a field bca_delete_flag of tinyint or bit
    and a field bca_add_date of datetime

  note: the *if 1=1* structure allows me to fold them and turn them on and off
 */
declare
        @Nrows int = 1000

if 1=1 /* testing the inner select */
begin
  select top (@Nrows) * 
    from bi_customer_actions
    where bca_delete_flag = 1
    order by bca_add_date
end

if 1=1 /* delete or update or select */
begin
  --select bca.*
  --update bca  set bca_delete_flag = 0
  delete bca
    from (
      select top (@Nrows) * 
        from bi_customer_actions
        where bca_delete_flag = 1
        order by bca_add_date
    ) as bca
end 

Run this from the branch where you want the file to end up:

git checkout otherbranch myfile.txt

General formulas:

git checkout <commit_hash> <relative_path_to_file_or_dir>
git checkout <remote_name>/<branch_name> <file_or_dir>

Some notes (from comments):

• Using the commit hash you can pull files from any commit
• This works for files and directories
• overwrites the file myfile.txt and mydir
• Wildcards don't work, but relative paths do
• Multiple paths can be specified

an alternative:

git show commit_id:path/to/file > path/to/file

The easiest way to get the finger print is to switch from app to signed report by clicking the drop down and click build.

Then you will be able to see the sha1 fingerprint at the bottom pane where you see the debug report and stack trace. N.B remember to switch back to app when you want to run your app on a device or an emulator.

Firefox

On Firefox you can use an extension called FirePHP which enables the logging and dumping of information from your PHP applications to the console. This is an addon to the awesome web development extension Firebug.

• http://www.studytrails.com/blog/using-firephp-in-firefox-to-debug-php/

Chrome

However if you are using Chrome there is a PHP debugging tool called Chrome Logger or webug (webug has problems with the order of logs).

More recently Clockwork is in active development which extends the Developer Tools by adding a new panel to provide useful debugging and profiling information. It provides out of the box support for Laravel 4 and Slim 2 and support can be added via its extensible API.

Using Xdebug

A better way to debug your PHP would be via Xdebug. Most browsers provide helper extensions to help you pass the required cookie/query string to initialize the debugging process.

• Chrome - Xdebug Helper
• Firefox - The easiest Xdebug
• Opera - Xdebug
• Safari - Xdebug Toggler

Take a look at java.text.DateFormat. Easier to use (with a bit less power) is the derived class, java.text.SimpleDateFormat

And here is a good intro to Java internationalization: http://java.sun.com/docs/books/tutorial/i18n/index.html (the "Formatting" section addressing your problem, and more).

The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format

<TextBox Text="{Binding Value,  StringFormat={}{0:#,0.0}}" 

In webkit-based browsers(Safari and Chrome), -webkit-transform is ignored on inline elements.. Set display: inline-block; to make it work. For demonstration/testing purposes, you may also want to use a negative angle or a transformation-origin lest the text is rotated out of the visible area.

More cleaner way using LINQ

var lines = dictionary.Select(kvp => kvp.Key + ": " + kvp.Value.ToString());
textBox3.Text = string.Join(Environment.NewLine, lines);

Although this won't limit the string to exactly 10 characters, why not let the browser do the work for you with CSS:

.no-overflow {
    white-space: no-wrap;
    text-overflow: ellipsis;
    overflow: hidden;
}

and then for the table cell that contains the string add the above class and set the maximum permitted width. The result should end up looking better than anything done based on measuring the string length.

Here is a bash script inspired by abarnert's answer which will unpack a package named MyPackage.pkg into a subfolder named MyPackage_pkg and then open the folder in Finder.

    #!/usr/bin/env bash
    filename="$*"
    dirname="${filename/\./_}"
    pkgutil --expand "$filename" "$dirname"
    cd "$dirname"
    tar xvf Payload
    open .

Usage:

    pkg-upack.sh MyPackage.pkg

Warning: This will not work in all cases, and will fail with certain files, e.g. the PKGs inside the OSX system installer. If you want to peek inside the pkg file and see what's inside, you can try SuspiciousPackage (free app), and if you need more options such as selectively unpacking specific files, then have a look at Pacifist (nagware).

You need to write a little PHP code. When user first click tab you can check is he like the page or not. Below is the sample code

include_once("facebook.php");

    // Create our Application instance.
    $facebook = new Facebook(array(
      'appId'  => FACEBOOK_APP_ID,
      'secret' => FACEBOOK_SECRET,
      'cookie' => true,
    ));

$signed_request = $facebook->getSignedRequest();

// Return you the Page like status
$like_status = $signed_request["page"]["liked"];

if($like_status)
{
    echo 'User Liked the page';
    // Place some content you wanna show to user

}else{
    echo 'User do not liked the page';
    // Place some content that encourage user to like the page
}

Java makes regex too complicated and it does not follow the perl-style. Take a look at MentaRegex to see how you can accomplish that in a single line of Java code:

String[] matches = match("aa11bb22", "/(\\d+)/g" ); // => ["11", "22"]

In my case, I knew the child component would always be present, but wanted to alter the state prior to the child initializing to save work.

I choose to test for the child until it appeared and make changes immediately, which saved me a change cycle on the child component.

export class GroupResultsReportComponent implements OnInit {

    @ViewChild(ChildComponent) childComp: ChildComponent;

    ngOnInit(): void {
        this.WhenReady(() => this.childComp, () => { this.childComp.showBar = true; });
    }

    /**
     * Executes the work, once the test returns truthy
     * @param test a function that will return truthy once the work function is able to execute 
     * @param work a function that will execute after the test function returns truthy
     */
    private WhenReady(test: Function, work: Function) {
        if (test()) work();
        else setTimeout(this.WhenReady.bind(window, test, work));
    }
}

Alertnatively, you could add a max number of attempts or add a few ms delay to the setTimeout. setTimeout effectively throws the function to the bottom of the list of pending operations.

This will also work

newData <- data*data

This also works - In the link HTML use onclick with return like this :

<a href="mypage.html" onclick="return confirmClick();">Delete</a>

And then the comfirmClick() function should be like:

function confirmClick() {
    if(confirm("Do you really want to delete this task?")) {
        return true;
    } else {
        return false;
    }
};

Try this. Just pass in the param you want to remove from the URL and the original URL value, and the function will strip it out for you.

function removeParam(key, sourceURL) {
    var rtn = sourceURL.split("?")[0],
        param,
        params_arr = [],
        queryString = (sourceURL.indexOf("?") !== -1) ? sourceURL.split("?")[1] : "";
    if (queryString !== "") {
        params_arr = queryString.split("&");
        for (var i = params_arr.length - 1; i >= 0; i -= 1) {
            param = params_arr[i].split("=")[0];
            if (param === key) {
                params_arr.splice(i, 1);
            }
        }
        if (params_arr.length) rtn = rtn + "?" + params_arr.join("&");
    }
    return rtn;
}

To use it, simply do something like this:

var originalURL = "http://yourewebsite.com?id=10&color_id=1";
var alteredURL = removeParam("color_id", originalURL);

The var alteredURL will be the output you desire.

Hope it helps!

I believe your best shot is to declare the list as a list of objects:

List<Object> anything = new ArrayList<Object>();

Then you can put whatever you want in it, like:

anything.add(new Employee(..))

Evidently, you will not be able to read anything out of the list without a proper casting:

Employee mike = (Employee) anything.get(0);

I would discourage the use of raw types like:

List anything = new ArrayList()

Since the whole purpose of generics is precisely to avoid them, in the future Java may no longer suport raw types, the raw types are considered legacy and once you use a raw type you are not allowed to use generics at all in a given reference. For instance, take a look a this another question: Combining Raw Types and Generic Methods

Yes, it's safe to delete these, although it may force a dynamic recompilation of any .NET applications you run on the server.

For background, see the Understanding ASP.NET dynamic compilation article on MSDN.

In Java terms, Scala's Seq would be Java's List, and Scala's List would be Java's LinkedList.

Note that Seq is a trait, which is equivalent to Java's interface, but with the equivalent of up-and-coming defender methods. Scala's List is an abstract class that is extended by Nil and ::, which are the concrete implementations of List.

So, where Java's List is an interface, Scala's List is an implementation.

Beyond that, Scala's List is immutable, which is not the case of LinkedList. In fact, Java has no equivalent to immutable collections (the read only thing only guarantees the new object cannot be changed, but you still can change the old one, and, therefore, the "read only" one).

Scala's List is highly optimized by compiler and libraries, and it's a fundamental data type in functional programming. However, it has limitations and it's inadequate for parallel programming. These days, Vector is a better choice than List, but habit is hard to break.

Seq is a good generalization for sequences, so if you program to interfaces, you should use that. Note that there are actually three of them: collection.Seq, collection.mutable.Seq and collection.immutable.Seq, and it is the latter one that is the "default" imported into scope.

There's also GenSeq and ParSeq. The latter methods run in parallel where possible, while the former is parent to both Seq and ParSeq, being a suitable generalization for when parallelism of a code doesn't matter. They are both relatively newly introduced, so people doesn't use them much yet.

The error is misleading - it says "pubkey" while pointing to a private key file ~/.ssh/id_rsa.

In my case, it was simply a missing public key (as I haven't restored it from a vault).

DETAILS

I used to skip deploying ~/.ssh/id_rsa.pub by automated scripts.

All ssh usages worked, but the error made me think of a possible mess.

Not at all - strace helped to notice that the trigger was actually the *.pub file:

strace ssh example.com
...
openat(AT_FDCWD, "/home/uvsmtid/.ssh/id_rsa.pub", O_RDONLY) = -1 ENOENT (No such file or directory)
...
write(2, "load pubkey \"/home/uvsmtid/.ssh/"..., 57) = 57
load pubkey "/home/uvsmtid/.ssh/id_rsa": invalid format

In Python 2.7, the / operator is an integer division if inputs are integers:

>>>20/15
1

>>>20.0/15.0
1.33333333333

>>>20.0/15
1.33333333333

In Python 3.3, the / operator is a float division even if the inputs are integer.

>>> 20/15
1.33333333333

>>>20.0/15
1.33333333333

For integer division in Python 3, we will use the // operator.

The // operator is an integer division operator in both Python 2.7 and Python 3.3.

In Python 2.7 and Python 3.3:

>>>20//15
1

Now, see the comparison

>>>a = 7.0/4.0
>>>b = 7/4
>>>print a == b

For the above program, the output will be False in Python 2.7 and True in Python 3.3.

In Python 2.7 a = 1.75 and b = 1.

In Python 3.3 a = 1.75 and b = 1.75, just because / is a float division.

I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.

You should use "merge a range of revision".

To merge changes from the trunk to a branch, inside the branch working copy choose "merge range of revisions" and enter the trunk URL and the start and end revisions to merge.

The same in the opposite way to merge a branch in the trunk.

About the --reintegrate flag, check the manual here: http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-merge.html#tsvn-dug-merge-reintegrate

string.join connects elements inside list of strings, not ints.

Use this generator expression instead :

values = ','.join(str(v) for v in value_list)

You need to make the x-factor into an ordered factor with the ordering you want, e.g

x <- data.frame("variable"=letters[1:5], "value"=rnorm(5)) ## example data
x <- x[with(x,order(-value)), ] ## Sorting
x$variable <- ordered(x$variable, levels=levels(x$variable)[unclass(x$variable)])

ggplot(x, aes(x=variable,y=value)) + geom_bar() +
   scale_y_continuous("",formatter="percent") + coord_flip()

I don't know any better way to do the ordering operation. What I have there will only work if there are no duplicate levels for x$variable.

This should get you started:

set datafile separator ","
plot 'infile' using 0:1

Performance wise StringBuffer is much better than String ; because whenever you apply concatenation on String Object then new String object are created on each concatenation.

Principal Rule : String are immutable(Non Modifiable) and StringBuffer are mutable(Modifiable)

Here is the programmatic experiment where you get the performance difference

public class Test {

  public static int LOOP_ITERATION= 100000;

  public static void stringTest(){
    long startTime = System.currentTimeMillis();
    String string = "This";
    for(int i=0;i<LOOP_ITERATION;i++){
        string = string+"Yasir";
    }

    long endTime = System.currentTimeMillis();
    System.out.println(endTime - startTime);    
  }

  public static void stringBufferTest(){
    long startTime = System.currentTimeMillis();
    StringBuffer stringBuffer = new StringBuffer("This");
    for(int i=0;i<LOOP_ITERATION;i++){
        stringBuffer.append("Yasir");
    }

    long endTime = System.currentTimeMillis();
    System.out.println(endTime - startTime);
  }

  public static void main(String []args){
    stringTest()
    stringBufferTest(); 
  }
 }

Output of String are in my machine 14800

Output of StringBuffer are in my machine 14

The function example:

func file_is_exists(f string) bool {
    _, err := os.Stat(f)
    if os.IsNotExist(err) {
        return false
    }
    return err == nil
}

In SQL Server 2017 STRING_AGG is added:

SELECT t.name,STRING_AGG (c.name, ',') AS csv
FROM sys.tables t
JOIN sys.columns c on t.object_id = c.object_id
GROUP BY t.name
ORDER BY 1

Also, STRING_SPLIT is usefull for the opposite case and available in SQL Server 2016

A few more relevant things to be noted:

const int a

• must be initialized.
• initialization must be at compile time.

readonly int a

• can use a default value, without initializing.
• initialization can be done at run time (Edit: within constructor only).

Simply use

dialog.setCanceledOnTouchOutside(true);

I believe this is an old question, and the Traffic was introduced by Github in 2014. Here is the link to the description of Traffic, that tells you the views on your repositories.

You can even try it this way:

[TestMethod]
public void ReadFiles()
{
    try
    {
        Read();
        return; // indicates success
    }
    catch (Exception ex)
    {
        Assert.Fail(ex.Message);
    }
}

"Is there a good way to handle this problem?" No. Nothing can be protected against reverse engineering. Even the firmware on DVD machines has been reverse engineered and the AACS Encryption key exposed. And that's in spite of the DMCA making that a criminal offense.

Since no technical method can stop your customers from reading your code, you have to apply ordinary commercial methods.

1. Licenses. Contracts. Terms and Conditions. This still works even when people can read the code. Note that some of your Python-based components may require that you pay fees before you sell software using those components. Also, some open-source licenses prohibit you from concealing the source or origins of that component.

2. Offer significant value. If your stuff is so good -- at a price that is hard to refuse -- there's no incentive to waste time and money reverse engineering anything. Reverse engineering is expensive. Make your product slightly less expensive.

3. Offer upgrades and enhancements that make any reverse engineering a bad idea. When the next release breaks their reverse engineering, there's no point. This can be carried to absurd extremes, but you should offer new features that make the next release more valuable than reverse engineering.

4. Offer customization at rates so attractive that they'd rather pay you to build and support the enhancements.

5. Use a license key which expires. This is cruel, and will give you a bad reputation, but it certainly makes your software stop working.

6. Offer it as a web service. SaaS involves no downloads to customers.

Timestamp is a Date: https://docs.oracle.com/javase/7/docs/api/java/sql/Timestamp.html

java.lang.Object
    java.util.Date
        java.sql.Timestamp

This works with me when db with usrname and password

mongoimport --db YOUR_DB --collection MyCollection --file /your_path/my_json_file.json -u my_user -p my_pass

db without username password please remove -u my_user -p my_pass

My sample json

{ 
    "_id" : ObjectId("5d11c815eb946a412ecd677d"), 
    "empid" : NumberInt(1), 
    "name" : "Rahul"
}
{ 
    "_id" : ObjectId("5d11c815eb946a412ecd677e"), 
    "empid" : NumberInt(2), 
    "name" : "Rahul"
}

Controller trying to find the "action" value in bean but according to your example you have not set any bean name of "action". try to do name="action". @RequestParam always find in the bean class.

For osX Mavericks Users you can install the ipa-file with the Apple Configurator. (Instead of the iPhone configuration utility, which crashes on OSX 10.9)

the First character of your function should be an Uppercase

So this question has been answered but to me the code used is not simple enough or complete. To me this bit here is what I was looking for and possibly some other people will like this as well.

string dateString = "198101";

if (DateTime.TryParse(dateString, out DateTime Temp) == true)
{
     //do stuff
}

The output is stored in Temp and not needed afterwards, datestring is the input string to be tested.

I think git branch -av only tells you what branches you have and which commit they're at, leaving you to infer which remote branches the local branches are tracking.

git remote show origin explicitly tells you which branches are tracking which remote branches. Here's example output from a repository with a single commit and a remote branch called abranch:

$ git branch -av
* abranch                d875bf4 initial commit
  master                 d875bf4 initial commit
  remotes/origin/HEAD    -> origin/master
  remotes/origin/abranch d875bf4 initial commit
  remotes/origin/master  d875bf4 initial commit

versus

$ git remote show origin
* remote origin
  Fetch URL: /home/ageorge/tmp/d/../exrepo/
  Push  URL: /home/ageorge/tmp/d/../exrepo/
  HEAD branch (remote HEAD is ambiguous, may be one of the following):
    abranch
    master
  Remote branches:
    abranch tracked
    master  tracked
  Local branches configured for 'git pull':
    abranch merges with remote abranch
    master  merges with remote master
  Local refs configured for 'git push':
    abranch pushes to abranch (up to date)
    master  pushes to master  (up to date)

In Notepad++, use replace all with regular expression. This has advantage over conversion command in menu that you can operate on entire folder w/o having to open each file or drag n drop (on several hundred files it will noticeably become slower) plus you can also set filename wildcard filter.

(\r?\n)|(\r\n?)

to

\n

This will match every possible line ending pattern (single \r, \n or \r\n) back to \n. (Or \r\n if you are converting to windows-style)

To operate on multiple files, either:

• Use "Replace All in all opened document" in "Replace" tab. You will have to drag and drop all files into Notepad++ first. It's good that you will have control over which file to operate on but can be slow if there several hundreds or thousands files.
• "Replace in files" in "Find in files" tab, by file filter of you choice, e.g., *.cpp *.cs under one specified directory.

Let's go over the basics: "Accessor" and "Mutator" are just fancy names fot a getter and a setter. A getter, "Accessor", returns a class's variable or its value. A setter, "Mutator", sets a class variable pointer or its value.

So first you need to set up a class with some variables to get/set:

public class IDCard
{
    private String mName;
    private String mFileName;
    private int mID;

}

But oh no! If you instantiate this class the default values for these variables will be meaningless. B.T.W. "instantiate" is a fancy word for doing:

IDCard test = new IDCard();

So - let's set up a default constructor, this is the method being called when you "instantiate" a class.

public IDCard()
{
    mName = "";
    mFileName = "";
    mID = -1;
}

But what if we do know the values we wanna give our variables? So let's make another constructor, one that takes parameters:

public IDCard(String name, int ID, String filename)
{
    mName = name;
    mID = ID;
    mFileName = filename;
}

Wow - this is nice. But stupid. Because we have no way of accessing (=reading) the values of our variables. So let's add a getter, and while we're at it, add a setter as well:

public String getName()
{
    return mName;
}

public void setName( String name )
{
    mName = name;
}

Nice. Now we can access mName. Add the rest of the accessors and mutators and you're now a certified Java newbie. Good luck.

Just replacing "Please enter your name" to your desired content would do the job. Am I missing something?

I'm not sure what you mean by "then again by the parser". After the splitting has been done, there's no further traversal of the string, only a traversal of the list of split strings. This will probably actually be the fastest way to accomplish this, so long as the size of your string isn't absolutely huge. The fact that python uses immutable strings means that you must always create a new string, so this has to be done at some point anyway.

If your string is very large, the disadvantage is in memory usage: you'll have the original string and a list of split strings in memory at the same time, doubling the memory required. An iterator approach can save you this, building a string as needed, though it still pays the "splitting" penalty. However, if your string is that large, you generally want to avoid even the unsplit string being in memory. It would be better just to read the string from a file, which already allows you to iterate through it as lines.

However if you do have a huge string in memory already, one approach would be to use StringIO, which presents a file-like interface to a string, including allowing iterating by line (internally using .find to find the next newline). You then get:

import StringIO
s = StringIO.StringIO(myString)
for line in s:
    do_something_with(line)

Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).

Otherwise, you might want to go with another JS library like jQuery or Mootools.

You can use the files from debug folder,however if you look at app debug informations with some inspection software,you can clearly see "Symbols File Name" which can reveals not wanted informations in path to the original exe file.

Use dt.days to obtain the days attribute as integers.

For eg:

In [14]: s = pd.Series(pd.timedelta_range(start='1 days', end='12 days', freq='3000T'))

In [15]: s
Out[15]: 
0    1 days 00:00:00
1    3 days 02:00:00
2    5 days 04:00:00
3    7 days 06:00:00
4    9 days 08:00:00
5   11 days 10:00:00
dtype: timedelta64[ns]

In [16]: s.dt.days
Out[16]:

1     3
2     5

More generally - You can use the .components property to access a reduced form of timedelta.

In [17]: s.dt.components
Out[17]: 
   days  hours  minutes  seconds  milliseconds  microseconds  nanoseconds

First, you gotta put your font as either a .otf or .ttf somewhere on your server.

Then use CSS to declare the new font family like this:

@font-face {
    font-family: MyFont;
    src: url('pathway/myfont.otf'); 
    }

If you link your document to the CSS file that you declared your font family in, you can use that font just like any other font.

After compiling it you can jar it.

The easiest way to do so is installing an older SDK to your newest Xcode.

How to install older SDK to the newest Xcode?

1. U can get the iOS 6.1 SDK from http://www.4shared.com/zip/NlPgsxz6/iPhoneOS61sdk.html or downloading an older Xcode and geting the SDK from its contents

2. Unzip and paste this folder to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs

3. Restart the xcode.

4. U can now select an older SDK on your project's build settings

Hope it helps you. It worked for me =)

TRUNCATE TABLE keeps all of your old indexing and whatnot. DROP TABLE would, obviously, get rid of the table and require you to recreate it later.

Yes. You can use Console of Sublime with (Linux):

Ctrl + `

And type:

view.settings().get('font_face')

Get any setting the same way.

The best thing I've found for diagnosing things like this is the service trace viewer. It's pretty simple to set up (assuming you can edit the configs):

Hope this helps.

This is C++11 code. In C++11, the && token can be used to mean an "rvalue reference".

Perhaps replace is what you are looking for:

> x = c(3, 2, 1, 0, 4, 0)
> replace(x, x==0, 1)
[1] 3 2 1 1 4 1

Or, if you don't have x (any specific reason why not?):

replace(c(3, 2, 1, 0, 4, 0), c(3, 2, 1, 0, 4, 0)==0, 1)

Many people are familiar with gsub, so you can also try either of the following:

as.numeric(gsub(0, 1, x))
as.numeric(gsub(0, 1, c(3, 2, 1, 0, 4, 0)))

Update

After reading the comments, perhaps with is an option:

Dinqyjs has a linq-like syntax and provides polyfills for functions like map and indexOf, and has been designed specifically for working with arrays in Javascript.

I had this problem with this kind of simple form:

public partial class MyForm : Form
{
    public MyForm()
    {
        Load += new EventHandler(Form1_Load);
    }

    private void Form1_Load(Object sender, EventArgs e)
    {
        InitializeComponent();
    }

    internal void UpdateLabel(string s)
    {
        Invoke(new Action(() => { label1.Text = s; }));
    }
}

Then for n other async threads I was using new MyForm().UpdateLabel(text) to try and call the UI thread, but the constructor gives no handle to the UI thread instance, so other threads get other instance handles, which are either Object reference not set to an instance of an object or Invoke or BeginInvoke cannot be called on a control until the window handle has been created. To solve this I used a static object to hold the UI handle:

public partial class MyForm : Form
{
    private static MyForm _mf;        

    public MyForm()
    {
        Load += new EventHandler(Form1_Load);
    }

    private void Form1_Load(Object sender, EventArgs e)
    {
        InitializeComponent();
        _mf = this;
    }

    internal void UpdateLabel(string s)
    {
        _mf.Invoke((MethodInvoker) delegate { _mf.label1.Text = s; });
    }
}

I guess it's working fine, so far...

You're getting this error because you're failing client authentication. Based on the error message, you probably have the default postgres configuration, which sets client authentication method to "IDENT" for all PostgreSQL connections.

You should definitely read section 19.1 Client Authentication in the PostgreSQL manual to better understand the authentication settings available (for each record in pg_hba.conf), but here is the relevant snippet to help with the problem you're having (from the version 9.5 manual):

trust

Allow the connection unconditionally. This method allows anyone that can connect to the PostgreSQL database server to login as any PostgreSQL user they wish, without the need for a password or any other authentication. See Section 19.3.1 for details.

reject

Reject the connection unconditionally. This is useful for "filtering out" certain hosts from a group, for example a reject line could block a specific host from connecting, while a later line allows the remaining hosts in a specific network to connect.

md5

Require the client to supply a double-MD5-hashed password for authentication. See Section 19.3.2 for details.

password

Require the client to supply an unencrypted password for authentication. Since the password is sent in clear text over the network, this should not be used on untrusted networks. See Section 19.3.2 for details.

gss

Use GSSAPI to authenticate the user. This is only available for TCP/IP connections. See Section 19.3.3 for details.

sspi

Use SSPI to authenticate the user. This is only available on Windows. See Section 19.3.4 for details.

ident

Obtain the operating system user name of the client by contacting the ident server on the client and check if it matches the requested database user name. Ident authentication can only be used on TCP/IP connections. When specified for local connections, peer authentication will be used instead. See Section 19.3.5 for details.

peer

Obtain the client's operating system user name from the operating system and check if it matches the requested database user name. This is only available for local connections. See Section 19.3.6 for details.

ldap

Authenticate using an LDAP server. See Section 19.3.7 for details.

radius

Authenticate using a RADIUS server. See Section 19.3.8 for details.

cert

Authenticate using SSL client certificates. See Section 19.3.9 for details.

pam

Authenticate using the Pluggable Authentication Modules (PAM) service provided by the operating system. See Section 19.3.10 for details.

So ... to solve the problem you're experiencing, you could do one of the following:

1. Change the authentication method(s) defined in your pg_hba.conf file to trust, md5, or password (depending on your security and simplicity needs) for the local connection records you have defined in there.

2. Update pg_ident.conf to map your operating system users to PostgreSQL users and grant them the corresponding access privileges, depending on your needs.

3. Leave the IDENT settings alone and create users in your database for each operating system user that you want to grant access to. If a user is already authenticated by the OS and logged in, PostgreSQL won't require further authentication and will grant access to that user based on whatever privileges (roles) are assigned to it in the database. This is the default configuration.

Note: The location of pg_hba.conf and pg_ident.conf is OS dependent.

GRANTs on different objects are separate. GRANTing on a database doesn't GRANT rights to the schema within. Similiarly, GRANTing on a schema doesn't grant rights on the tables within.

If you have rights to SELECT from a table, but not the right to see it in the schema that contains it then you can't access the table.

The rights tests are done in order:

Do you have `USAGE` on the schema? 
    No:  Reject access. 
    Yes: Do you also have the appropriate rights on the table? 
        No:  Reject access. 
        Yes: Check column privileges.

Your confusion may arise from the fact that the public schema has a default GRANT of all rights to the role public, which every user/group is a member of. So everyone already has usage on that schema.

The phrase:

(assuming that the objects' own privilege requirements are also met)

Is saying that you must have USAGE on a schema to use objects within it, but having USAGE on a schema is not by itself sufficient to use the objects within the schema, you must also have rights on the objects themselves.

It's like a directory tree. If you create a directory somedir with file somefile within it then set it so that only your own user can access the directory or the file (mode rwx------ on the dir, mode rw------- on the file) then nobody else can list the directory to see that the file exists.

If you were to grant world-read rights on the file (mode rw-r--r--) but not change the directory permissions it'd make no difference. Nobody could see the file in order to read it, because they don't have the rights to list the directory.

If you instead set rwx-r-xr-x on the directory, setting it so people can list and traverse the directory but not changing the file permissions, people could list the file but could not read it because they'd have no access to the file.

You need to set both permissions for people to actually be able to view the file.

Same thing in Pg. You need both schema USAGE rights and object rights to perform an action on an object, like SELECT from a table.

(The analogy falls down a bit in that PostgreSQL doesn't have row-level security yet, so the user can still "see" that the table exists in the schema by SELECTing from pg_class directly. They can't interact with it in any way, though, so it's just the "list" part that isn't quite the same.)

.gitignore will only ignore files that you haven't already added to your repository.

If you did a git add ., and the file got added to the index, .gitignore won't help you. You'll need to do git rm sites/default/settings.php to remove it, and then it will be ignored.

For Swift, Just write this code

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == .Delete {
            print("Delete Hit")
        }
}

For Objective C, Just write this code

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
       if (editingStyle == UITableViewCellEditingStyleDelete) {           
            NSLog(@"index: %@",indexPath.row);
           }
}

In Python3.6, the StringIO and cStringIO modules are gone, you should use io.StringIO instead.So you should do this like the first answer:

import sys
from io import StringIO

old_stdout = sys.stdout
old_stderr = sys.stderr
my_stdout = sys.stdout = StringIO()
my_stderr = sys.stderr = StringIO()

# blah blah lots of code ...

sys.stdout = self.old_stdout
sys.stderr = self.old_stderr

// if you want to see the value of redirect output, be sure the std output is turn back
print(my_stdout.getvalue())
print(my_stderr.getvalue())

my_stdout.close()
my_stderr.close()

Code:

List<String> list = new ArrayList<String>();

list.add("a");

JSONArray array = new JSONArray();

for (int i = 0; i < list.size(); i++) {
    array.put(list.get(i));
}
JSONObject obj = new JSONObject();

try {
    obj.put("result", array);
} catch (JSONException e) {
    e.printStackTrace();
}

To integrate SAP Crystal Reports with Visual Studio 2017 below steps needs to be followed right:

• Uninstall all installed components from system related to Crystal Report. [If any]
• Install compatible Crystal Report Developer Edition (as per target VS) with administrator priviledge. [As of writing, latest compatible service pack is 23]
  • Install appropriate Crystal Report Runtime (x86/ x64) for Visual Studio. [Not mandatory]
• Open solution in VS and remove all assembly references from project related to Crystal Report. [If any]
• Include following assembly references in project:
  • CrystalDecisions.CrystalReports.Engine
  • CrystalDecisions.ReportSource
  • CrystalDecisions.Shared
  • CrystalDecisions.CrystalReports.Design
  • CrystalDecisions.VSDesigner
• Make sure "Copy Local" property is set to "True" in reference properties.
• Build/ Rebuild project.

facing similar problem to you. In my case I have 1000's of files from cisco logs that I need to parse manually.

In order to be flexible with fields and types I have successfully tested using StringIO + read_cvs which indeed does accept a dict for the dtype specification.

I usually get each of the files ( 5k-20k lines) into a buffer and create the dtype dictionaries dynamically.

Eventually I concatenate ( with categorical... thanks to 0.19) these dataframes into a large data frame that I dump into hdf5.

Something along these lines

import pandas as pd
import io 

output = io.StringIO()
output.write('A,1,20,31\n')
output.write('B,2,21,32\n')
output.write('C,3,22,33\n')
output.write('D,4,23,34\n')

output.seek(0)


df=pd.read_csv(output, header=None,
        names=["A","B","C","D"],
        dtype={"A":"category","B":"float32","C":"int32","D":"float64"},
        sep=","
       )

df.info()

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 5 entries, 0 to 4
Data columns (total 4 columns):
A    5 non-null category
B    5 non-null float32
C    5 non-null int32
D    5 non-null float64
dtypes: category(1), float32(1), float64(1), int32(1)
memory usage: 205.0 bytes
None

Not very pythonic.... but does the job

Hope it helps.

typeid can operate at runtime, and return an object describing the run time type of the object, which must be a pointer to an object of a class with virtual methods in order for RTTI (run-time type information) to be stored in the class. It can also give the compile time type of an expression or a type name, if not given a pointer to a class with run-time type information.

typeof is a GNU extension, and gives you the type of any expression at compile time. This can be useful, for instance, in declaring temporary variables in macros that may be used on multiple types. In C++, you would usually use templates instead.

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

Subscribing to # gives you a subscription to everything except for topics that start with a $ (these are normally control topics anyway).

It is better to know what you are subscribing to first though, of course, and note that some broker configurations may disallow subscribing to # explicitly.

You can use the excellent jquery-Json plugin:

Makes it easy to convert to and from Json objects.

If your image is rounded, it would have a height and width of the exact same size (i.e 120). You simply take half of that number and use that in your code (image.layer.cornerRadius = 60).

Do not mix 12 and 15, use this

I used this library called Parser. It worked for what I needed.

import React, { Component } from 'react';    
import Parser from 'html-react-parser';

class MyComponent extends Component {
  render() {
    <div>{Parser(this.state.message)}</div>
  }
};

Both are same as kill -sigkill processID, kill -9 processID. Its basically for forced termination of the process.

Try to see if the following code helps you:

Try change update="insTable:display" to update="display". I believe you cannot prefix the id with the form ID like that.

Sven Marnach excellent solution is directly translatable into ElementTree which is part of recent Python distributions:

from xml.etree import ElementTree as ET

s = """<table>
  <tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
  <tr><td>a</td><td>b</td><td>c</td></tr>
  <tr><td>d</td><td>e</td><td>f</td></tr>
  <tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""

table = ET.XML(s)
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
    values = [col.text for col in row]
    print(dict(zip(headers, values)))

same output as Sven Marnach's answer...

Simply think Val like final Variable in java

<h1><a href="/" title="Some title">Name</a></h1>

h1 a{
  width: {logo width};
  height: {logo height};
  display:block;
  text-indent:-9999px;
  background:url({ logo url});
}

Similar to one post above, (except I was using admin credentials) to get S3 uploads to work with large 50M file.

Initially my error was:

An error occurred (AccessDenied) when calling the CreateMultipartUpload operation: Access Denied

I switched the multipart_threshold to be above the 50M

aws configure set default.s3.multipart_threshold 64MB

and I got:

An error occurred (AccessDenied) when calling the PutObject operation: Access Denied

I checked bucket public access settings and all was allowed. So I found that public access can be blocked on account level for all S3 buckets:

You will need to install the Apple Developer Tools. Once you have done that, the easiest thing is to either use the Xcode IDE or use gcc, or nowadays better cc (the clang LLVM compiler), from the command line.

According to Apple's site, the latest version of Xcode (3.2.1) only runs on Snow Leopard (10.6) so if you have an earlier version of OS X you will need to use an older version of Xcode. Your Mac should have come with a Developer Tools DVD which will contain a version that should run on your system. Also, the Apple Developer Tools site still has older versions available for download. Xcode 3.1.4 should run on Leopard (10.5).

You can specify it in your IDE. For example, for Eclipse in Run Configurations ? VM arguments. You can enter -Xmx800m -Xms500m as

I'm sure this question is about to die now that RHEL 5 is nearing end of life, but the answer seems to have gotten a lot simpler now:

sudo yum install epel-release
sudo yum install git

worked for me on a fresh install of CentOS 5.11.

I liked user1333423's solution except that it always re-sized every column; i needed to allow some columns to be fixed width. So in this version columns with a width set to "Auto" will be auto-sized and those set to a fixed amount will not be auto-sized.

public class AutoSizedGridView : GridView
{
    HashSet<int> _autoWidthColumns;

    protected override void PrepareItem(ListViewItem item)
    {
        if (_autoWidthColumns == null)
        {
            _autoWidthColumns = new HashSet<int>();

            foreach (var column in Columns)
            {
                if(double.IsNaN(column.Width))
                    _autoWidthColumns.Add(column.GetHashCode());
            }                
        }

        foreach (GridViewColumn column in Columns)
        {
            if (_autoWidthColumns.Contains(column.GetHashCode()))
            {
                if (double.IsNaN(column.Width))
                    column.Width = column.ActualWidth;

                column.Width = double.NaN;

I tried many different solutions for restoring my postgres backup. I ran into permission denied problems on MacOS, no solutions seemed to work.

Here's how I got it to work:

Postgres comes with Pgadmin4. If you use macOS you can press CMD+SPACE and type pgadmin4 to run it. This will open up a browser tab in chrome.

If you run into errors getting pgadmin4 to work, try killall pgAdmin4 in your terminal, then try again.

Steps to getting pgadmin4 + backup/restore

1. Create the backup

Do this by rightclicking the database -> "backup"

2. Give the file a name.

Like test12345. Click backup. This creates a binary file dump, it's not in a .sql format

3. See where it downloaded

There should be a popup at the bottomright of your screen. Click the "more details" page to see where your backup downloaded to

4. Find the location of downloaded file

In this case, it's /users/vincenttang

5. Restore the backup from pgadmin

Assuming you did steps 1 to 4 correctly, you'll have a restore binary file. There might come a time your coworker wants to use your restore file on their local machine. Have said person go to pgadmin and restore

Do this by rightclicking the database -> "restore"

6. Select file finder

Make sure to select the file location manually, DO NOT drag and drop a file onto the uploader fields in pgadmin. Because you will run into error permissions. Instead, find the file you just created:

7. Find said file

You might have to change the filter at bottomright to "All files". Find the file thereafter, from step 4. Now hit the bottomright "Select" button to confirm

8. Restore said file

You'll see this page again, with the location of the file selected. Go ahead and restore it

9. Success

If all is good, the bottom right should popup an indicator showing a successful restore. You can navigate over to your tables to see if the data has been restored propery on each table.

10. If it wasn't successful:

Should step 9 fail, try deleting your old public schema on your database. Go to "Query Tool"

Execute this code block:

DROP SCHEMA public CASCADE; CREATE SCHEMA public;

Now try steps 5 to 9 again, it should work out

Summary

This is how I had to backup/restore my backup on Postgres, when I had error permission issues and could not log in as a superuser. Or set credentials for read/write using chmod for folders. This workflow works for a binary file dump default of "Custom" from pgadmin. I assume .sql is the same way, but I have not yet tested that

Shortly: gene_name[x] is a mutable object so it cannot be hashed. To use an object as a key in a dictionary, python needs to use its hash value, and that's why you get an error.

Further explanation:

Mutable objects are objects which value can be changed. For example, list is a mutable object, since you can append to it. int is an immutable object, because you can't change it. When you do:

a = 5;
a = 3;

You don't change the value of a, you create a new object and make a point to its value.

Mutable objects cannot be hashed. See this answer.

To solve your problem, you should use immutable objects as keys in your dictionary. For example: tuple, string, int.

Because you're using php-fpm, you should make sure that php-fpm user is the same as nginx user.

Check /etc/php-fpm.d/www.conf and set php user and group to nginx if it's not.

The php-fpm user needs write permission.

Change your second table code like below.

<table style="border: 1px solid red;width:300px;display:block;">
<thead>
    <tr>
        <td width=150>Name</td>
        <td width=150>phone</td>
    </tr>
</thead>
<tbody style='height:50px;overflow:auto;display:block;width:317px;'>
    <tr>
        <td width=150>AAAA</td>
        <td width=150>323232</td>
    </tr>
    <tr>
        <td>BBBBB</td>
        <td>323232</td>
    </tr>
    <tr>
        <td>CCCCC</td>
        <td>3435656</td>
    </tr>
</tbody>
</table>

JSFIDDLE DEMO

MyClass is a class not a namespace. So this code is wrong:

using MyClass //THIS CODE IS NOT CORRECT

You should check the namespace of the MyClass (e.g: MyNamespace). Then call it in a proper way:

MyNamespace.MyClass myClass =new MyNamespace.MyClass();

In my opinion it's easiest to work in a 'private browsing session' of chrome, to ensure that your javascript files don't come from the cache.

In Oracle database we can achieve like this.

CREATE TABLE Student(
  StudentID Number(38, 0) not null,
  DepartmentID Number(38, 0) not null,
  PRIMARY KEY (StudentID, DepartmentID)
);

You can use some inline CSS like this

<input type="submit" name="submit" style="background: url(images/stack.png); width:100px; height:25px;" />

Should do the magic, also you may wanna do a border:none; to get rid of the standard borders.

After trying most of the solutions here, the easiest thing I found was the obvious - using a temp file. I'm not sure what you want to do with your multiple line output, but you can then deal with it line by line using read. About the only thing you can't really do is easily stick it all in the same variable, but for most practical purposes this is way easier to deal with.

./myscript.sh > /tmp/foo
while read line ; do 
    echo 'whatever you want to do with $line'
done < /tmp/foo

Quick hack to make it do the requested action:

result=""
./myscript.sh > /tmp/foo
while read line ; do
  result="$result$line\n"
done < /tmp/foo
echo -e $result

Note this adds an extra line. If you work on it you can code around it, I'm just too lazy.

EDIT: While this case works perfectly well, people reading this should be aware that you can easily squash your stdin inside the while loop, thus giving you a script that will run one line, clear stdin, and exit. Like ssh will do that I think? I just saw it recently, other code examples here: https://unix.stackexchange.com/questions/24260/reading-lines-from-a-file-with-bash-for-vs-while

One more time! This time with a different filehandle (stdin, stdout, stderr are 0-2, so we can use &3 or higher in bash).

result=""
./test>/tmp/foo
while read line  <&3; do
    result="$result$line\n"
done 3</tmp/foo
echo -e $result

you can also use mktemp, but this is just a quick code example. Usage for mktemp looks like:

filenamevar=`mktemp /tmp/tempXXXXXX`
./test > $filenamevar

Then use $filenamevar like you would the actual name of a file. Probably doesn't need to be explained here but someone complained in the comments.

OK, just change your code to something like this:

<script>
function submit() {
   return confirm('Do you really want to submit the form?');
}
</script>

<form onsubmit="return submit(this);">
   <input type="image" src="xxx" border="0" name="submit" onclick="show_alert();"
      alt="PayPal - The safer, easier way to pay online!" value="Submit">
</form>

Also this is the code in run, just I make it easier to see how it works, just run the code below to see the result:

function submitForm() {_x000D_
  return confirm('Do you really want to submit the form?');_x000D_
}

<form onsubmit="return submitForm(this);">_x000D_
  <input type="text" border="0" name="submit" />_x000D_
  <button value="submit">submit</button>_x000D_
</form>

Try this:

import time

t_end = time.time() + 60 * 15
while time.time() < t_end:
    # do whatever you do

This will run for 15 min x 60 s = 900 seconds.

Function time.time returns the current time in seconds since 1st Jan 1970. The value is in floating point, so you can even use it with sub-second precision. In the beginning the value t_end is calculated to be "now" + 15 minutes. The loop will run until the current time exceeds this preset ending time.

Try to find HEAD and _HEAD between the lines and delete this words in project.pbxproj. Backup this file before doing this..

This is how it works: Lets suppose the administrator is looking for records of student

Robert'); DROP TABLE STUDENTS; --

Since the admin account has high privileges deleting the table from this account is possible.

The code to retrieve user name from request is

Now the query would be something like this (to search the student table)

String query="Select * from student where username='"+student_name+"'";

statement.executeQuery(query); //Rest of the code follows

The resultant query becomes

Select * from student where username='Robert'); DROP TABLE STUDENTS; --

Since the user input is not sanitized, The above query has is manipulated into 2 parts

Select * from student where username='Robert'); 

DROP TABLE STUDENTS; --

The double dash (--) will just comment out remaining part of the query.

This is dangerous as it can nullify password authentication, if present

The first one will do the normal search.

The second one will drop the table student if the account has sufficient privileges (Generally the school admin account will run such query and will have the privileges talked about above).

Use the below quesry:

select employee_name,salary,department_id from emp where salary in(select max(salary) from emp group by department_id);

C++17

C++17 (upcoming standard) changes the synopsis of the template basic_string adding a non const overload of data():

charT* data() noexcept;

Returns: A pointer p such that p + i == &operator for each i in [0,size()].

CharT const * from std::basic_string<CharT>

std::string const cstr = { "..." };
char const * p = cstr.data(); // or .c_str()

CharT * from std::basic_string<CharT>

std::string str = { "..." };
char * p = str.data();

C++11

CharT const * from std::basic_string<CharT>

std::string str = { "..." };
str.c_str();

CharT * from std::basic_string<CharT>

From C++11 onwards, the standard says:

1. The char-like objects in a basic_string object shall be stored contiguously. That is, for any basic_string object s, the identity &*(s.begin() + n) == &*s.begin() + n shall hold for all values of n such that 0 <= n < s.size().

---

2. const_reference operator[](size_type pos) const;
reference operator[](size_type pos);

   Returns: *(begin() + pos) if pos < size(), otherwise a reference to an object of type CharT with value CharT(); the referenced value shall not be modified.

---

3. const charT* c_str() const noexcept;
const charT* data() const noexcept;

   Returns: A pointer p such that p + i == &operator[](i) for each i in [0,size()].

There are severable possible ways to get a non const character pointer.

1. Use the contiguous storage of C++11

std::string foo{"text"};
auto p = &*foo.begin();

Pro

• Simple and short
• Fast (only method with no copy involved)

Cons

• Final '\0' is not to be altered / not necessarily part of the non-const memory.

2. Use std::vector<CharT>

std::string foo{"text"};
std::vector<char> fcv(foo.data(), foo.data()+foo.size()+1u);
auto p = fcv.data();

Pro

• Simple
• Automatic memory handling
• Dynamic

Cons

• Requires string copy

3. Use std::array<CharT, N> if N is compile time constant (and small enough)

std::string foo{"text"};
std::array<char, 5u> fca;
std::copy(foo.data(), foo.data()+foo.size()+1u, fca.begin());

Pro

• Simple
• Stack memory handling

Cons

• Static
• Requires string copy

4. Raw memory allocation with automatic storage deletion

std::string foo{ "text" };
auto p = std::make_unique<char[]>(foo.size()+1u);
std::copy(foo.data(), foo.data() + foo.size() + 1u, &p[0]);

Pro

• Small memory footprint
• Automatic deletion
• Simple

Cons

• Requires string copy
• Static (dynamic usage requires lots more code)
• Less features than vector or array

5. Raw memory allocation with manual handling

std::string foo{ "text" };
char * p = nullptr;
try
{
  p = new char[foo.size() + 1u];
  std::copy(foo.data(), foo.data() + foo.size() + 1u, p);
  // handle stuff with p
  delete[] p;
}
catch (...)
{
  if (p) { delete[] p; }
  throw;
}

Pro

• Maximum 'control'

Con

• Requires string copy
• Maximum liability / susceptibility for errors
• Complex

exit code 139 (people say this means memory fragmentation)

No, it means that your program died with signal 11 (SIGSEGV on Linux and most other UNIXes), also known as segmentation fault.

Could anybody tell me why the run fails but debug doesn't?

Your program exhibits undefined behavior, and can do anything (that includes appearing to work correctly sometimes).

Your first step should be running this program under Valgrind, and fixing all errors it reports.

If after doing the above, the program still crashes, then you should let it dump core (ulimit -c unlimited; ./a.out) and then analyze that core dump with GDB: gdb ./a.out core; then use where command.

Here's a much cleaner solution for ES6 that I see isn't included here. It uses the Set and the spread operator: ...

var a = [1, 1, 2];

[... new Set(a)]

Which returns [1, 2]

Though this question is rather old and has already been answered, I just want to add a note on how to do proper exception handling in C++11:

Use std::nested_exception and std::throw_with_nested

It is described on StackOverflow here and here, how you can get a backtrace on your exceptions inside your code without need for a debugger or cumbersome logging, by simply writing a proper exception handler which will rethrow nested exceptions.

Since you can do this with any derived exception class, you can add a lot of information to such a backtrace! You may also take a look at my MWE on GitHub, where a backtrace would look something like this:

Library API: Exception caught in function 'api_function'
Backtrace:
~/Git/mwe-cpp-exception/src/detail/Library.cpp:17 : library_function failed
~/Git/mwe-cpp-exception/src/detail/Library.cpp:13 : could not open file "nonexistent.txt"

Simply app.use means “Run this on ALL requests”
app.get means “Run this on a GET request, for the given URL”

Simple example:

public function productsAction()
{
    $saveFileName = 'ceneo.xml';
    $filename = $this->path . $saveFileName;
    if(file_exists($filename)) {

    $reader = new XMLReader();
    $reader->open($filename);

    $countElements = 0;

    while($reader->read()) {
        if($reader->nodeType == XMLReader::ELEMENT) {
            $nodeName = $reader->name;
        }

        if($reader->nodeType == XMLReader::TEXT && !empty($nodeName)) {
            switch ($nodeName) {
                case 'id':
                    var_dump($reader->value);
                    break;
            }
        }

        if($reader->nodeType == XMLReader::END_ELEMENT && $reader->name == 'offer') {
            $countElements++;
        }
    }
    $reader->close();
    exit(print('<pre>') . var_dump($countElements));
    }
}

If you simply call interrupt(), the thread will not automatically be closed. Instead, the Thread might even continue living, if isInterrupted() is implemented accordingly. The only way to guaranteedly close a thread, as asked for by OP, is

Thread.currentThread().stop();

Method is deprecated, however.

Calling return only returns from the current method. This only terminates the thread if you're at its top level.

Nevertheless, you should work with interrupt() and build your code around it.

I ended up using this quick piece of code that did exactly what I needed:

final JFileChooser fc = new JFileChooser();
fc.showOpenDialog(this);

try {
    // Open an input stream
    Scanner reader = new Scanner(fc.getSelectedFile());
}

A solution where the logo is truly centered and the links are justified.

The max recommended number of links for the nav is 6, depending on the length of the words in eache link.

If you have 5 links, insert an empty link and style it with:

class="hidden-xs" style="visibility: hidden;"

in this way the number of links is always even.

Fiddle

Not sure if it will fix your particular issue but worth sharing anyway.

I had issues with twitter boot strap in IE. No rounded corners. Navigation menu not collapsing. Spans not sitting in correct location, even some images not displaying.

Strangely, site works okay in IE when run through visual studio debugger, its once deployed to a server that the problem occurs.

Try using IE developer tools (F12 is keyboard shortcut) Check your browser mode and document mode. (its at the top along side the menu bar)

Problem happened for me as document was IE7 and browser was IE10 compatibility. I added a http header in IIS: Name X-UA-Compatible Value IE=EmulateIE9

Now the page loads as document - IE9 standards, browser IE10 compatibility and all the previous issues are resolved.

Hope this helps.

1) Use maven dependency plugin

Create a simple project with pom.xml only. Add your dependency and run:

mvn dependency:tree

Unfortunately dependency mojo must use pom.xml or you get following error:

Cannot execute mojo: tree. It requires a project with an existing pom.xml, but the build is not using one.

2) Find pom.xml of your artifact in maven central repository

Dependencies are described In pom.xml of your artifact. Find it using maven infrastructure.

Go to https://search.maven.org/ and enter your groupId and artifactId.

Or you can go to https://repo1.maven.org/maven2/ and navigate first using plugins groupId, later using artifactId and finally using its version.

For example see org.springframework:spring-core

3) Use maven dependency plugin against your artifact

Part of dependency artifact is a pom.xml. That specifies it's dependency. And you can execute mvn dependency:tree on this pom.
