$conn=new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
    // If this is your connection then you have to assign null
    // to your connection variable as follows:
$conn=null;
    // By this way you can close connection in PDO.

JavaScript does not have associative arrays. It has objects.

The following lines of code all do exactly the same thing - set the 'name' field on an object to 'orion'.

var f = new Object(); f.name = 'orion';
var f = new Object(); f['name'] = 'orion';
var f = new Array(); f.name = 'orion';
var f = new Array(); f['name'] = 'orion';
var f = new XMLHttpRequest(); f['name'] = 'orion';

It looks like you have an associative array because an Array is also an Object - however you're not actually adding things into the array at all; you're setting fields on the object.

Now that that is cleared up, here is a working solution to your example:

var text = '{ name = oscar }'
var dict = new Object();

// Remove {} and spaces
var cleaned = text.replace(/[{} ]/g, '');

// Split into key and value
var kvp = cleaned.split('=');

// Put in the object
dict[ kvp[0] ] = kvp[1];
alert( dict.name ); // Prints oscar.

It's just a method on your form, you can call it just like any other method. You just have to create an EventArgs object to pass to it, (and pass it the handle of the button as sender)

This worked for me:

sudo rm /var/lib/mongodb/mongod.lock    
sudo service mongodb restart

Jython has some limitations:

There are a number of differences. First, Jython programs cannot use CPython extension modules written in C. These modules usually have files with the extension .so, .pyd or .dll. If you want to use such a module, you should look for an equivalent written in pure Python or Java. Although it is technically feasible to support such extensions - IronPython does so - there are no plans to do so in Jython.

Distributing my Python scripts as JAR files with Jython?

you can simply call python scripts (or bash or Perl scripts) from Java using Runtime or ProcessBuilder and pass output back to Java:

Running a bash shell script in java

Running Command Line in Java

java runtime.getruntime() getting output from executing a command line program

Try this instead in the end:

exec (@query)

If you do not have the brackets, SQL Server assumes the value of the variable to be a stored procedure name.

OR

EXECUTE sp_executesql @query

And it should not be because of FULL JOIN.
But I hope you have already created the temp tables: #TrafficFinal, #TrafficFinal2, #TrafficFinal3 before this.

Please note that there are performance considerations between using EXEC and sp_executesql. Because sp_executesql uses forced statement caching like an sp.
More details here.

On another note, is there a reason why you are using dynamic sql for this case, when you can use the query as is, considering you are not doing any query manipulations and executing it the way it is?

Also from angularJs documentation:

I have found that "get-task-allow" needs to be checked for Development builds but unchecked for Distribution builds. The easiest way to accomplish this (AFAIK) is to have two entitlements files in your project: Entitlements.plist and EntitlementsDebug.plist - and to reference the proper one in the build project settings for the various configurations in your project.

Without actual data it is hard to answer the question but I guess you are looking for something like this:

Top15['Citable docs per Capita'].corr(Top15['Energy Supply per Capita'])

That calculates the correlation between your two columns 'Citable docs per Capita' and 'Energy Supply per Capita'.

To give an example:

import pandas as pd

df = pd.DataFrame({'A': range(4), 'B': [2*i for i in range(4)]})

   A  B
0  0  0
1  1  2
2  2  4
3  3  6

Then

df['A'].corr(df['B'])

gives 1 as expected.

Now, if you change a value, e.g.

df.loc[2, 'B'] = 4.5

   A    B
0  0  0.0
1  1  2.0
2  2  4.5
3  3  6.0

the command

df['A'].corr(df['B'])

returns

0.99586

which is still close to 1, as expected.

If you apply .corr directly to your dataframe, it will return all pairwise correlations between your columns; that's why you then observe 1s at the diagonal of your matrix (each column is perfectly correlated with itself).

df.corr()

will therefore return

          A         B
A  1.000000  0.995862
B  0.995862  1.000000

In the graphic you show, only the upper left corner of the correlation matrix is represented (I assume).

There can be cases, where you get NaNs in your solution - check this post for an example.

If you want to filter entries above/below a certain threshold, you can check this question. If you want to plot a heatmap of the correlation coefficients, you can check this answer and if you then run into the issue with overlapping axis-labels check the following post.

you can use this https://github.com/ManuCutillas/ng2-responsive Hope it helps :-)

Commonly base64 it is used for images. if you like to decode an image (jpg in this example with org.apache.commons.codec.binary.Base64 package):

byte[] decoded = Base64.decodeBase64(imageJpgInBase64);
FileOutputStream fos = null;
fos = new FileOutputStream("C:\\output\\image.jpg");
fos.write(decoded);
fos.close();

How about:

<meta http-equiv="refresh" content="5;url=http://site.com/file.ext">

This way works on all browsers (i think) and let you put a message like: "If the download doesn't start in five seconds, click here."

If you need it to be with javascript.. well...

document.write('<meta http-equiv="refresh" content="5;url=http://site.com/file.ext">');

You can try:

top -bn1 | grep "Cpu(s)" | \
           sed "s/.*, *\([0-9.]*\)%* id.*/\1/" | \
           awk '{print 100 - $1"%"}'

In a function call the single star turns a list into seperate arguments (e.g. zip(*x) is the same as zip(x1,x2,x3) if x=[x1,x2,x3]) and the double star turns a dictionary into seperate keyword arguments (e.g. f(**k) is the same as f(x=my_x, y=my_y) if k = {'x':my_x, 'y':my_y}.

In a function definition it's the other way around: the single star turns an arbitrary number of arguments into a list, and the double start turns an arbitrary number of keyword arguments into a dictionary. E.g. def foo(*x) means "foo takes an arbitrary number of arguments and they will be accessible through the list x (i.e. if the user calls foo(1,2,3), x will be [1,2,3])" and def bar(**k) means "bar takes an arbitrary number of keyword arguments and they will be accessible through the dictionary k (i.e. if the user calls bar(x=42, y=23), k will be {'x': 42, 'y': 23})".

To export all documents from ElasticSearch into JSON, you can use the esbackupexporter tool. It works with index snapshots. It takes the container with snapshots (S3, Azure blob or file directory) as the input and outputs one or several zipped JSON files per index per day. It is quite handy when exporting your historical snapshots. To export your hot index data, you may need to make the snapshot first (see the answers above).

A bit late answer, but I suggest you have a look at a not well known project on codeplex called ConferenceXP

ConferenceXP is an open source research platform that provides simple, flexible, and extensible conferencing and collaboration using high-bandwidth networks and the advanced multimedia capabilities of Microsoft Windows. ConferenceXP helps researchers and educators develop innovative applications and solutions that feature broadcast-quality audio and video in support of real-time distributed collaboration and distance learning environments.

Full source (it's huge!) is provided. It implements the RTP protocol.

This removes html code or php if you supplement it. Allows you to add trailing slash and it come up as well as the url without the trailing slash all bypassing the 404 code. Plus a little added security.

All the answers so far are mathematically wrong. Returning rand() % N does not uniformly give a number in the range [0, N) unless N divides the length of the interval into which rand() returns (i.e. is a power of 2). Furthermore, one has no idea whether the moduli of rand() are independent: it's possible that they go 0, 1, 2, ..., which is uniform but not very random. The only assumption it seems reasonable to make is that rand() puts out a Poisson distribution: any two nonoverlapping subintervals of the same size are equally likely and independent. For a finite set of values, this implies a uniform distribution and also ensures that the values of rand() are nicely scattered.

This means that the only correct way of changing the range of rand() is to divide it into boxes; for example, if RAND_MAX == 11 and you want a range of 1..6, you should assign {0,1} to 1, {2,3} to 2, and so on. These are disjoint, equally-sized intervals and thus are uniformly and independently distributed.

The suggestion to use floating-point division is mathematically plausible but suffers from rounding issues in principle. Perhaps double is high-enough precision to make it work; perhaps not. I don't know and I don't want to have to figure it out; in any case, the answer is system-dependent.

The correct way is to use integer arithmetic. That is, you want something like the following:

#include <stdlib.h> // For random(), RAND_MAX

// Assumes 0 <= max <= RAND_MAX
// Returns in the closed interval [0, max]
long random_at_most(long max) {
  unsigned long
    // max <= RAND_MAX < ULONG_MAX, so this is okay.
    num_bins = (unsigned long) max + 1,
    num_rand = (unsigned long) RAND_MAX + 1,
    bin_size = num_rand / num_bins,
    defect   = num_rand % num_bins;

  long x;
  do {
   x = random();
  }
  // This is carefully written not to overflow
  while (num_rand - defect <= (unsigned long)x);

  // Truncated division is intentional
  return x/bin_size;
}

The loop is necessary to get a perfectly uniform distribution. For example, if you are given random numbers from 0 to 2 and you want only ones from 0 to 1, you just keep pulling until you don't get a 2; it's not hard to check that this gives 0 or 1 with equal probability. This method is also described in the link that nos gave in their answer, though coded differently. I'm using random() rather than rand() as it has a better distribution (as noted by the man page for rand()).

If you want to get random values outside the default range [0, RAND_MAX], then you have to do something tricky. Perhaps the most expedient is to define a function random_extended() that pulls n bits (using random_at_most()) and returns in [0, 2**n), and then apply random_at_most() with random_extended() in place of random() (and 2**n - 1 in place of RAND_MAX) to pull a random value less than 2**n, assuming you have a numerical type that can hold such a value. Finally, of course, you can get values in [min, max] using min + random_at_most(max - min), including negative values.

My personal opinion is that you should avoid using JSP/ASP/PHP/etc pages. Instead output to an API similar to SAX (only designed for calling rather than handling). That way there is a single layer that has to create well formed output.

To generate a random number between min and max, use:

int randNum = rand()%(max-min + 1) + min;

(Includes max and min)

No, there is no such possibility. Allthough, one could imagine:

public static boolean contains(String s, Collection<String>c) {
    for (String ss : c) {
       if (s.equalsIgnoreCase(ss)) return true;
    }
    return false;
}

On Ubuntu:

Wed Jan 27 10:21:32 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:84 exception: connect failed

Solution

look for if mongodb is running by following command:

ps -ef | grep mongo

If mongo is not running you get:

 vimal     1806  1698  0 10:11 pts/0    00:00:00 grep --color=auto mongo

You are seeing that the mongo daemon is not there.

Then start it through configuration file(with root priev):

root@vimal:/data# mongod --config /etc/mongodb.conf &
[1] 2131
root@vimal:/data# all output going to: /var/log/mongodb/mongodb.log

you can see the other details:

root@vimal:~# more /etc/mongodb.conf

Open a new terminal to see the result of mongod --config /etc/mongodb.conf & then type mongo. It should be running or grep

root@vimal:/data# ps -ef | grep mongo

root      3153     1  2 11:39 ?        00:00:23 mongod --config /etc/mongodb.conf
root      3772  3489  0 11:55 pts/1    00:00:00 grep --color=auto mongo 

NOW

root@vimal:/data# mongo

MongoDB shell version: 2.0.4
connecting to: test

you get the mongoDB shell

This is not the end of story. I will post the repair method so that it starts automatically every time, most development machine shutdowns every day and the VM must have mongo started automatically at next boot.

You'll do it the same way you would apply a css selector. For instanse you can do

$("#mydiv > .myclass")

or

$("#mydiv .myclass")

The last one will match every myclass inside myDiv, including myclass inside myclass.

Use " That should work.

You can use this code:

int count;
            try {
                URL url = new URL(f_url[0]);
                URLConnection conection = url.openConnection();
                conection.setConnectTimeout(TIME_OUT);
                conection.connect();
                // Getting file length
                int lenghtOfFile = conection.getContentLength();
                // Create a Input stream to read file - with 8k buffer
                InputStream input = new BufferedInputStream(url.openStream(),
                        8192);
                // Output stream to write file
                OutputStream output = new FileOutputStream(
                        "/sdcard/9androidnet.jpg");

                byte data[] = new byte[1024];
                long total = 0;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    // publishing the progress....
                    // After this onProgressUpdate will be called
                    publishProgress("" + (int) ((total * 100) / lenghtOfFile));
                    // writing data to file
                    output.write(data, 0, count);
                }
                // flushing output
                output.flush();
                // closing streams
                output.close();
                input.close();
            } catch (SocketTimeoutException e) {
                connectionTimeout=true;
            } catch (Exception e) {
                Log.e("Error: ", e.getMessage());
            }

In the latest version (v2.19 for Windows when I'm writing), if you choose the option "Use git in Windows command prompt" (or sth similar, please read the options carefully when you install git), you should be able to use git commands in windows command prompt or windows powershell without any additional setting. Just remember to restart the command line tool after you install git.

convert_objects is deprecated.

For pandas >= 0.17.0, use pd.to_numeric

df["2nd"] = pd.to_numeric(df["2nd"])

Using history.listen

For example like below:

In your component,

componentWillMount() {
    this.props.history.listen(() => {
      // Detecting, user has changed URL
      console.info(this.props.history.location.pathname);
    });
}

Ideally, have a keyword table containing the fields:

Keyword
Id
Count (possibly)

with an index on Keyword. Create an insert/update/delete trigger on the other table so that, when a row is changed, every keyword is extracted and put into (or replaced in) this table.

You'll also need a table of words to not count as keywords (if, and, so, but, ...).

In this way, you'll get the best speed for queries wanting to look for the keywords and you can implement (relatively easily) more complex queries such as "contains Java and RCA1802".

"LIKE" queries will work but they won't scale as well.

Scenario 1 - you don't have a data-source for the items
You can just populate the ComboBox with static values as follows -
From XAML:

<ComboBox Height="23" Name="comboBox1" Width="120">
        <ComboBoxItem Content="X"/>
        <ComboBoxItem Content="Y"/>
        <ComboBoxItem Content="Z"/>
</ComboBox>  

Or, from CodeBehind:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    comboBox1.Items.Add("X");
    comboBox1.Items.Add("Y");
    comboBox1.Items.Add("Z");
}  

Scenario 2.a - you have a data-source, and the items never get changed
You can use the data-source to populate the ComboBox. Any IEnumerable type can be used as the data-source. You need to assign it to the ItemsSource property of the ComboBox and that'll do just fine (it's up to you how you populate the IEnumerable).

Scenario 2.b - you have a data-source, and the items might get changed
You should use an ObservableCollection<T> as the data-source and assign it to the ItemsSource property of the ComboBox (it's up to you how you populate the ObservableCollection<T>). Using an ObservableCollection<T> ensures that whenever an item is added to or removed from the data-source, the change will reflect immediately on the UI.

I tested Github Flavored Markdown for a while and can summarize with four rules:

1. punctuation marks will be dropped
2. leading white spaces will be dropped
3. upper case will be converted to lower
4. spaces between letters will be converted to -

For example, if your section is named this:

## 1.1 Hello World

Create a link to it this way:

[Link](#11-hello-world)

A JSON document basically consists of lists and dictionaries. There is no obvious way to map such a datastructure on a two-dimensional table.

it's so easy...converting a date to calendar like this:

Calendar cal=Calendar.getInstance();
DateFormat format=new SimpleDateFormat("yyyy/mm/dd");
format.format(date);
cal=format.getCalendar();

I use this custom binding (based on this fiddle by RP Niemeyer, see his answer to this question), which makes sure the numeric value is properly converted from string to number (as suggested by the solution of Michael Best):

Javascript:

ko.bindingHandlers.valueAsNumber = {
    init: function (element, valueAccessor, allBindingsAccessor) {
        var observable = valueAccessor(),
            interceptor = ko.computed({
                read: function () {
                    var val = ko.utils.unwrapObservable(observable);
                    return (observable() ? observable().toString() : observable());
                },
                write: function (newValue) {
                    observable(newValue ? parseInt(newValue, 10) : newValue);
                },
                owner: this
            });
        ko.applyBindingsToNode(element, { value: interceptor });
    }
};

Example HTML:

<select data-bind="valueAsNumber: level, event:{ change: $parent.permissionChanged }">
    <option value="0"></option>
    <option value="1">R</option>
    <option value="2">RW</option>
</select>

This SO answer might help in this case.
If the main project already references the resource project, then you could just explicitly work with your generated-resource class in your code, and access its ResourceManager from that. Hence, something along the lines of:

ResourceManager resMan = YeagerTechResources.Resources.ResourceManager;

// then, you could go on working with that
ResourceSet resourceSet = resMan.GetResourceSet(CultureInfo.CurrentUICulture, true, true);
// ...

You can use ExtendedXmlSerializer to serialize and deserialize.

Instalation You can install ExtendedXmlSerializer from nuget or run the following command:

Install-Package ExtendedXmlSerializer

Serialization:

ExtendedXmlSerializer serializer = new ExtendedXmlSerializer();
var obj = new Message();
var xml = serializer.Serialize(obj);

Deserialization

var obj2 = serializer.Deserialize<Message>(xml);

Standard XML Serializer in .NET is very limited.

• Does not support serialization of class with circular reference or class with interface property,
• Does not support Dictionaries,
• There is no mechanism for reading the old version of XML,
• If you want create custom serializer, your class must inherit from IXmlSerializable. This means that your class will not be a POCO class,
• Does not support IoC.

ExtendedXmlSerializer can do this and much more.

ExtendedXmlSerializer support .NET 4.5 or higher and .NET Core. You can integrate it with WebApi and AspCore.

As mentioned by Seeker, the problem could have been that you setup the click() function too soon. From your code snippet, we cannot know where you placed the script and whether it gets run at the right time.

An important point is to run such scripts after the document is ready. This is done by placing the click() initialization within that other function as in:

jQuery(document).ready(function()
  {
    jQuery("body").click(function()
      {
        // ... your click code here ...
      });
  });

This is usually the best method, especially if you include your JavaScript code in your <head> tag. If you include it at the very bottom of the page, then the ready() function is less important, but it may still be useful.

I think the OP is asking the wrong question. The code below will show that it not necessary to manually raise the PropertyChanged EVENT from a dependency property to achieve the desired result. The way to do it is handle the PropertyChanged CALLBACK on the dependency property and set values for other dependency properties there. The following is a working example. In the code below, MyControl has two dependency properties - ActiveTabInt and ActiveTabString. When the user clicks the button on the host (MainWindow), ActiveTabString is modified. The PropertyChanged CALLBACK on the dependency property sets the value of ActiveTabInt. The PropertyChanged EVENT is not manually raised by MyControl.

Although the previous answers all seem to say that you can just move the directory and there are no absolute paths in the .git structure. I found this to be untrue when using git from Cygwin.

When I moved my git repo (in fact I restored it from a backup, but to a different drive as my drive structure changed on my new system). I got an error message like

fatal: Invalid path '<part_of_the_original_repo_path>': No such file or directory

I used grep to find that in my .git/config file in the [core] section is a worktree variable which holds the absolute path of my git repo. Changing this fixed the problem for me.

I don't know of a way to do that (you can get the language and try to deduct the locale from that).

I tried to cook a little something to try and do that (only tested on Firefox with one locale). should work as long as the short date string includes the date as digits, so it might fail for, say, arabic. It might have other bugs too, i don't know all the different locales peculiarities, this is just a concept...

function getShortDateFormat() {
    var d = new Date(1992, 0, 7);
    var s = d.toLocaleDateString();

    function formatReplacer(str) {
        var num = parseInt(str);
        switch (num % 100) {
            case 92:
                return str.replace(/.{1}/g, "Y");
            case 1:
                return str.length == 1 ? "mM" : "MM"
            case 7:
                return str.length == 1 ? "dD" : "DD"
        }
    }

    shortDateFormat = s.replace(/\d+/g, formatReplacer);
    return shortDateFormat;
}

getShortDateFormat();

The outputted format will be:

• Y: the number of digits to represent years
• dD = short day (i.e. use only one digit when possible)
• DD = long day format (i.e. two digits always)
• mM/MM - same for months

So in my browser, the shortDateformat you get is "MM/DD/YYYY".

You can use the CONCAT function to do that:

UPDATE tbl SET col=CONCAT('test',col);

If you want to get cleverer and only update columns which don't already have test prepended, try

UPDATE tbl SET col=CONCAT('test',col)
WHERE col NOT LIKE 'test%';

I have set the vm argument in WAS server as -Dfile.encoding=UTF-8 to change the servers' default character set.

In case anyone needed the above in swift :

SWIFT 3.0 and above :

this will capitalize your string, make the first letter capital :

viewNoteDateMonth.text  = yourString.capitalized

this will uppercase your string, make all the string upper case :

viewNoteDateMonth.text  = yourString.uppercased()

with open("filename.txt", "w+") as file:
  for line in file:
    print line

This with statement automatically opens and closes it for you and you can iterate over the lines of the file with a simple for loop

I came across the same problem and solved it as following for VB.NET. It's the .NET Framework so you should be possible to adapt. Wanted to compare my solution and now I see that nobody seems to solve it my way.

Make a field declaration.

Private _currentDataView as DataView

So looping through all the rows and searching for a cell containing a value that I know is next to the cell I want to change works for me.

Public Sub SetCellValue(ByVal value As String)
    Dim dataView As DataView = _currentDataView

    For i As Integer = 0 To dataView.Count - 1
        If dataView(i).Row.Item("projID").ToString.Equals("139") Then
            dataView(i).Row.Item("Comment") = value
            Exit For ' Exit early to save performance
        End If
    Next
End Sub

So that you can better understand it. I know that ColumnName "projID" is 139. I loop until I find it and then I can change the value of "ColumnNameofCell" in my case "Comment". I use this for comments added on runtime.

It is easy if you are using django version 3.1 and above

def login_view(request):
    if(request.POST):
        yourForm= YourForm(request.POST)
        itemValue = yourForm['your_filed_name'].value()
        # Check if you get the value
        return HttpResponse(itemValue )
    else:
        return render(request, "base.html")

HashMap is a Map implementation, allowing duplicate values but not duplicate keys.. For adding an object a Key/Value pair is required. Null Keys and Null values are allowed. eg:

{The->3,world->5,is->2,nice->4}

HashSet is a Set implementation,which does not allow duplicates.If you tried to add a duplicate object, a call to public boolean add(Object o) method, then the set remains unchanged and returns false. eg:

[The,world,is,nice]

Just a heads up that Bootstrap 4 now uses img-fluid instead of img-responsive, so double check which version you're using if you're having problems.

The database must have a name (example DB1), try this one:

OracleConnection con = new OracleConnection("data source=DB1;user id=fastecit;password=fastecit"); 

In case the TNS is not defined you can also try this one:

OracleConnection con = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=DB1)));
User Id=fastecit;Password=fastecit"); 

This code:

from scipy.stats import linregress

linregress(x,y) #x and y are arrays or lists.

gives out a list with the following:

slope : float
slope of the regression line
intercept : float
intercept of the regression line
r-value : float
correlation coefficient
p-value : float
two-sided p-value for a hypothesis test whose null hypothesis is that the slope is zero
stderr : float
Standard error of the estimate

Since HTML does not have an "include" directive, I can think only of three workarounds

1. Frames
2. Javascript
3. CSS

A little comment on each of the methods.

Frames can be either standard frames or iFrames. Either way, you will have to specify a fixed height for them, so this might not be the solution you are looking for.

Javascript is a pretty broad subject and there probably exist many ways how one might use it to achieve the desired effect. Off the top of my head however I can think of two ways:

1. Full-blown AJAX request, which requests the header/footer and then places them in the right place of the page;
2. <script type="text/javascript" src="header.js"> which has something like this in it: document.write('My header goes here');

Doing it via CSS would be really an abuse. CSS has the content property which allows you to insert some HTML content, although it's not really intended to be used like this. Also I'm not sure about browser support for this construct.

This obviously solution was not mentioned earlier. You can also use cookies to pass data from the browser back to the server.

Just set a cookie with the data you want to pass to PHP using javascript in the browser.

Then, simply read this cookie on the PHP side.

A (dirty) possible solution is by using patterns,

here is an example with an inside stroked triangle :

https://jsfiddle.net/qr3p7php/5/

<style>
#triangle1{
  fill: #0F0;
  fill-opacity: 0.3;
  stroke: #000;
  stroke-opacity: 0.5;
  stroke-width: 20;
}
#triangle2{
  stroke: #f00;
  stroke-opacity: 1;
  stroke-width: 1;
}    
</style>

<svg height="210" width="400" >
    <pattern id="fagl" patternUnits="objectBoundingBox" width="2" height="1" x="-50%">
        <path id="triangle1" d="M150 0 L75 200 L225 200 Z">
    </pattern>    
    <path id="triangle2" d="M150 0 L75 200 L225 200 Z" fill="url(#fagl)"/>
</svg>

libsysfs does look potentially useful, but not directly from a shell script. There's a program that comes with it called systool which will do what you want, though it may be easier to just look in /sys directly rather than using another program to do it for you.

start sound

startSound("mp3/ba.mp3");

method

private void startSound(String filename) {
    AssetFileDescriptor afd = null;
    try {
        afd = getResources().getAssets().openFd(filename);
    } catch (IOException e) {
        e.printStackTrace();
    }
    MediaPlayer player = new MediaPlayer();
    try {
        assert afd != null;
        player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
    } catch (IOException e) {
        e.printStackTrace();
    }
    try {
        player.prepare();
    } catch (IOException e) {
        e.printStackTrace();
    }
    player.start();
}

For a very fast and simple solution where you check equality against a single value, you can use the mask method.

df.mask(df == ' ')

there is a function called isNaN it return true if it's (Not-a-number) , so u can check for a number this way

if(!isNaN(miscCharge))
{
   //do some thing if it's a number
}else{
   //do some thing if it's NOT a number
}

hope it works

I'm in the same spot myself (or was), FWIW I ended up checking out to a samba share on the Linux host and editing that share locally on the Windows machine with notepad++, then I compiled on the Linux box via PuTTY. (We weren't allowed to update the ten y/o versions of the editors on the Linux host and it didn't have Java, so I gave up on X11 forwarding)

Now... I run modern Linux in a VM on my Windows host, add all the tools I want (e.g. CDT) to the VM and then I checkout and build in a chroot jail that closely resembles the RTE.

It's a clunky solution but I thought I'd throw it in to the mix.

1. Go to "Database" Menu option
2. Select the "Reverse Engineer" option.
3. A wizard will be open and it will generate the ER Diagram for you.

I think this would do it:

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript">
    $(document).ready(function(){

         $(".divlink").click(function(){
         $("#content").attr("src" , $(this).attr("ref"));

});

});
</script>
</head>
<body>
<iframe id="content"></iframe>

<a href="#" ref="page1.html" class="divlink" >Page 1</a><br />
<a href="#" ref="page2.html" class="divlink" >Page 2</a><br />
<a href="#" ref="page3.html" class="divlink" >Page 3</a><br />
<a href="#" ref="page4.html" class="divlink" >Page 4</a><br />
<a href="#" ref="page5.html" class="divlink" >Page 5</a><br />
<a href="#" ref="page6.html" class="divlink" >Page 6</a><br />
</body>
</html>

By the way if you can avoid Jquery, you can just use the target attribute of <a> element:

<html>
<body>
<iframe id="content" name="content"></iframe>

<a href="page1.html" target="content" >Page 1</a><br />
<a href="page2.html" target="content" >Page 2</a><br />
<a href="page3.html" target="content" >Page 3</a><br />
<a href="page4.html" target="content" >Page 4</a><br />
<a href="page5.html" target="content" >Page 5</a><br />
<a href="page6.html" target="content" >Page 6</a><br />
</body>
</html> 

SELECT DATEADD(m,DATEDIFF(m,0,GETDATE())-1,0) AS PreviousMonthStart

SELECT DATEADD(ms,-2,DATEADD(month, DATEDIFF(month, 0, GETDATE()), 0)) AS PreviousMonthEnd

I just faced the same issue and solved it using the following.First clear tracked files by using :

git clean -d -f

then try git pull origin master

You can view other git clean options by typing git clean -help

In a few words: The constructor is called first, then any @FXML annotated fields are populated, then initialize() is called.

This means the constructor does not have access to @FXML fields referring to components defined in the .fxml file, while initialize() does have access to them.

Quoting from the Introduction to FXML:

[...] the controller can define an initialize() method, which will be called once on an implementing controller when the contents of its associated document have been completely loaded [...] This allows the implementing class to perform any necessary post-processing on the content.

Python is garbage-collected, so if you reduce the size of your list, it will reclaim memory. You can also use the "del" statement to get rid of a variable completely:

biglist = [blah,blah,blah]
#...
del biglist

What huge codes for something so simple:

In C#, create an extension method and use LINQ.

public static int CountOccurences(this string s, char c)
{
    return s.Count(t => t == c);
}

Usage:

int count = "toto is the best".CountOccurences('t');

Result: 4.

A lot of responses on here are addressing the how but not the why. PHP $_SESSION key/value pairs are stored on the server. This differs from a cookie, which is stored on the browser. This is why you are able to access values in a cookie from both PHP and JavaScript. To make matters worse, AJAX requests from the browser do not include any of the cookies you have set for the website. So, you will have to make JavaScript pull the Session ID cookie and include it in every AJAX request for the server to be able to make heads or tails of it. On the bright side, PHP Sessions are designed to fail-over to a HTTP GET or POST variable if cookies are not sent along with the HTTP headers. I would look into some of the principles of RESTful web applications and use of of the design patterns that are common with those kinds of applications instead of trying to mangle with the session handler.

You should declare it with declarations array(meta property) of @NgModule as shown below (RC5 and later),

import {CoursesComponent} from './courses.component';

@NgModule({
  imports:      [ BrowserModule],
  declarations: [ AppComponent,CoursesComponent],  //<----here
  providers:    [],      
  bootstrap:    [ AppComponent ]
})

On Linux, you can get rid of "Managed by your organization" Chrome policies, by removing these directories (as sudo probably):

/etc/opt/chrome/policies
/etc/opt/chrome/policies/managed
/etc/opt/chrome/policies/recommended

"1,2,3,4".split(",") as strings

"1,2,3,4".split(",").map { |s| s.to_i } as integers

Try javax.net.ssl.keyStorePassword instead of javax.net.ssl.keyPassword: the latter isn't mentioned in the JSSE ref guide.

The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmExceptions are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.

You could also use -Djavax.net.debug=ssl, or at least -Djavax.net.debug=ssl,keymanager, to get more debugging information, if the information in the stack trace isn't sufficient.

Most of the base R answers address the situation where only one data.frame has additional columns or that the resulting data.frame would have the intersection of the columns. Since the OP writes I am hoping to retain the columns that do not match after the bind, an answer using base R methods to address this issue is probably worth posting.

Below, I present two base R methods: One that alters the original data.frames, and one that doesn't. Additionally, I offer a method that generalizes the non-destructive method to more than two data.frames.

First, let's get some sample data.

# sample data, variable c is in df1, variable d is in df2
df1 = data.frame(a=1:5, b=6:10, d=month.name[1:5])
df2 = data.frame(a=6:10, b=16:20, c = letters[8:12])

Two data.frames, alter originals
In order to retain all columns from both data.frames in an rbind (and allow the function to work without resulting in an error), you add NA columns to each data.frame with the appropriate missing names filled in using setdiff.

# fill in non-overlapping columns with NAs
df1[setdiff(names(df2), names(df1))] <- NA
df2[setdiff(names(df1), names(df2))] <- NA

Now, rbind-em

rbind(df1, df2)
    a  b        d    c
1   1  6  January <NA>
2   2  7 February <NA>
3   3  8    March <NA>
4   4  9    April <NA>
5   5 10      May <NA>
6   6 16     <NA>    h
7   7 17     <NA>    i
8   8 18     <NA>    j
9   9 19     <NA>    k
10 10 20     <NA>    l

Note that the first two lines alter the original data.frames, df1 and df2, adding the full set of columns to both.

Two data.frames, do not alter originals
To leave the original data.frames intact, first loop through the names that differ, return a named vector of NAs that are concatenated into a list with the data.frame using c. Then, data.frame converts the result into an appropriate data.frame for the rbind.

rbind(
  data.frame(c(df1, sapply(setdiff(names(df2), names(df1)), function(x) NA))),
  data.frame(c(df2, sapply(setdiff(names(df1), names(df2)), function(x) NA)))
)

Many data.frames, do not alter originals
In the instance that you have more than two data.frames, you could do the following.

# put data.frames into list (dfs named df1, df2, df3, etc)
mydflist <- mget(ls(pattern="df\\d+"))
# get all variable names
allNms <- unique(unlist(lapply(mydflist, names)))

# put em all together
do.call(rbind,
        lapply(mydflist,
               function(x) data.frame(c(x, sapply(setdiff(allNms, names(x)),
                                                  function(y) NA)))))

Maybe a bit nicer to not see the row names of original data.frames? Then do this.

do.call(rbind,
        c(lapply(mydflist,
                 function(x) data.frame(c(x, sapply(setdiff(allNms, names(x)),
                                                    function(y) NA)))),
          make.row.names=FALSE))

Creating a dictionary as it has mentioned, but in this case each key has the name of the object name that you want to create. Then the value is set as the class you want to instantiate, see for example:

class MyClass:
   def __init__(self, name):
       self.name = name
       self.checkme = 'awesome {}'.format(self.name)
...

instanceNames = ['red', 'green', 'blue']

# Here you use the dictionary
holder = {name: MyClass(name=name) for name in instanceNames}

Then you just call the holder key and you will have all the properties and methods of your class available for you.

holder['red'].checkme

output:

'awesome red'

I was facing such a problem, look at the picture below

and here is its HTML

<tr class="li1">
    <td valign="top">1.</td>
    <td colspan="5" valign="top">
        <p>How to build e-book learning environment</p>
    </td>
</tr>

so I fix it by changing valign Attribute in both td tags to baseline

and it worked

here is the result

hope this help you

Use '›'

› -> single right angle quote. For single left angle quote, use ‹

If you are using java 8 the use of the internal Base64 encoder and decoder can be avoided by replacing

return new BASE64Encoder().encode(bytes);

with

return Base64.getEncoder().encodeToString(bytes);

and

return new BASE64Decoder().decodeBuffer(property);

with

return Base64.getDecoder().decode(property);

Note that this solution doesn't protect your data as the methods for decrypting are stored in the same place. It just makes it more difficult to break. Mainly it avoids to print it and show it to everybody by mistake.

Word of warning: if you put config files in your WEB-INF/classes folder, and your IDE, say Eclipse, does a clean/rebuild, it will nuke your conf files unless they were in the Java source directory. BalusC's great answer alludes to that in option 1 but I wanted to add emphasis.

I learned the hard way that if you "copy" a web project in Eclipse, it does a clean/rebuild from any source folders. In my case I had added a "linked source dir" from our POJO java library, it would compile to the WEB-INF/classes folder. Doing a clean/rebuild in that project (not the web app project) caused the same problem.

I thought about putting my confs in the POJO src folder, but these confs are all for 3rd party libs (like Quartz or URLRewrite) that are in the WEB-INF/lib folder, so that didn't make sense. I plan to test putting it in the web projects "src" folder when i get around to it, but that folder is currently empty and having conf files in it seems inelegant.

So I vote for putting conf files in WEB-INF/commonConfFolder/filename.properties, next to the classes folder, which is Balus option 2.

I found a better way than reload the page. instead i will reload the data that just got updated. this way faster n better

parameter?: type is a shorthand for parameter: type | undefined

You can look at outline with offset but this needs some padding to exists on your div. Or you can absolutely position a border div inside, something like

<div id='parentDiv' style='position:relative'>
  <div id='parentDivsContent'></div>
  <div id='fakeBordersDiv' 
       style='position: absolute;width: 100%;
              height: 100%;
              z-index: 2;
              border: 2px solid;
              border-radius: 2px;'/>
</div>

You might need to fiddle with margins on the fake borders div to fit it as you like.

You can also try /etc/redhat-release or /etc/fedora-release:

cat /etc/fedora-release 
Fedora release 7 (Moonshine)

• Click on start menu.
• Click run
• In the open box, type cmd then click ok
• At the command prompt, enter:

  c:>pscp source_file_name userid@server_name:/path/destination_file_name.

c:>pscp november2012 [email protected]:/mydata/november2012.

• When promted, enter your password for server.

You should read the documentation on storing stuff externally on Android. There's a multitude of problems that could exist with your current code, and I think going over the documentation might help you iron them out.

You did not really ask an actual question, but since this is a general use case I'm using quite often here's what I do. You may try this yourself and see if the error persists.

My assumption on your use case:

You have an existing directory containing files and directories and now want to convert it into a Git repository that is cloned from some place else without changing any data in your current directory.

There are really two ways.

Clone repo - mv .git - git reset --hard

This method is what you did - to clone the existing repository into an empty directory, then move the .git directory into the destination directory. To work without problems, this generally requires you then to run

git reset --hard

However, that would change the state of files in your current directory. You can try this on a full copy/rsync of your directory and study what changes. At least afterwards you should no longer see discrepancies between git log and status.

Init new repository - point to origin

The second is less disturbing: cd into your destination, and start a new repository with

git init

Then you tell that new repository, that it has an ancestor some place else:

git remote add origin original_git_repo_path

Then safely

git fetch origin master

to copy over the data without changing your local files. Everything should be fine now.

I always recommend the second way for being less error-prone.

I have a solution for you.

Just you need to install a plugin named Indent By Fold.

You can install this by going through Plugins -> Plugin Manager -> Show Plugin Manager. OR Plugins -> Plugins Admin -> chekmark Indent By Fold from list than install

Then just select the list item and all you need is to type the first word then you got it.

you can use this plugin from a plugin in the menu bar.

The following steps are necessary to create .exe i.e. executable files which are as 1) Open visual studio framework 2) Then, create a new project or application 3) Build or execute your application by pressing F5

Try this

fileTarget="xorg-x11-fonts*"

filesFound=$(ls $fileTarget)  # 2014-04-03 edit 2: removed dbl-qts around $(...)

edit 2014-04-03 (removed dbl-quotes and added test file 'Charlie 22.html' (2 spaces)

case ${filesFound} in
  "" ) printf "NO files found for target=${fileTarget}\n" ;;
   * ) printf "FileTarget Files found=${filesFound}\n" ;;
esac 

Test

fileTarget="*.html"  # where I have some html docs in the current dir

FileTarget Files found=Baby21.html
baby22.html
charlie  22.html
charlie21.html
charlie22.html
charlie23.html

fileTarget="xorg-x11-fonts*"

NO files found for target=xorg-x11-fonts*

Note that this only works in the current directory, or where the var fileTarget includes the path you are want to inspect.

  $(this).data('dont',0);
}

Remeber that $.data() would work only for items with ID.

This works just fine, but instead of

name = input('Enter name of text file: ')+'.txt' 

you should use

name = raw_input('Enter name of text file: ')+'.txt'

along with

open(name,'a') or open(name,'w')

There is a condition that most of these solutions do not address. I revised Patrick Honorez's solution to handle it. I felt I had to share this because I was pulling my hair out when the original function was occasionally clearing more data that I expected.

The situation happens when the table only has one column and the .SpecialCells(xlCellTypeConstants).ClearContents attempts to clear the contents of the top row. In this situation, only one cell is selected (the top row of the table that only has one column) and the SpecialCells command applies to the entire sheet instead of the selected range. What was happening to me was other cells on the sheet that were outside of my table were also getting cleared.

I did some digging and found this advice from Mathieu Guindon: Range SpecialCells ClearContents clears whole sheet

Range({any single cell}).SpecialCells({whatever}) seems to work off the entire sheet.

Range({more than one cell}).SpecialCells({whatever}) seems to work off the specified cells.

If the list/table only has one column (in row 1), this revision will check to see if the cell has a formula and if not, it will only clear the contents of that one cell.

Deprecated features in PHP 5.5.x

The original MySQL extension is now deprecated, and will generate E_DEPRECATED errors when connecting to a database. Instead, use the **MYSQLi or PDO_MySQL extensions.**

Syntax:

<?php
  $connect = mysqli_connect('localhost', 'user', 'password', 'dbname');

Also, replace all mysql_* functions into mysqli_* functions

instead of

<?php
 $connect = mysql_connect('localhost','root','');
  mysql_select_db('dbname');
?> 

   $array[0] = 1;
   $array[2] = 2;
   $arrayTxt = implode( ',', $array);
   $sql = "SELECT * FROM table WHERE some_id in ($arrayTxt)"

@tasseKATT's Answer is great, but if you don't want to make a directive, why not use $document?

.controller('ExampleController', ['$scope', '$document', function($scope, $document) {
  var dumb = function (id) {
  var queryResult = $document[0].getElementById(id)
  var wrappedID = angular.element(queryResult);
  return wrappedID;
};

PLUNKR

The best option is create a directive and wrap the slider features there. The secret is use $timeout, the jquery code will be called only when DOM is ready.

angular.module('app')
.directive('my-slider', 
    ['$timeout', function($timeout) {
        return {
            restrict:'E',
            scope: true,
            template: '<div id="{{ id }}"></div>',
            link: function($scope) {
                $scope.id = String(Math.random()).substr(2, 8);

                $timeout(function() {
                    angular.element('#'+$scope.id).slider();                    
                });
            }
        };
    }]
);

You can do this in a try and catch block:

try:
    if val is None:
        print("null")
except NameError:
    # throw an exception or do something else

If you're encoding a string to put in a URL component (a querystring parameter), you should call encodeURIComponent.

If you're encoding an existing URL, call encodeURI.

If you want to delete all the .pyc files from the project folder.

First, you have

cd <path/to/the/folder>

then find all the .pyc file and delete.

find . -name \*.pyc -delete

Another interesting way to listen file input changes is with a watch over the ng-model attribute of the input file. Off course FileModel is a custom directive.

Like this:

HTML -> <input type="file" file-model="change.fnEvidence">

JS Code ->

$scope.$watch('change.fnEvidence', function() {
                    alert("has changed");
                });

Hope it can helps someone.

One can reproduce the error with the code below:

public ActionResult ClosingTheConnectionAction(){
   try
   {
      //we need to set buffer to false to
      //make sure data is written in chunks
      Response.Buffer = false;  
      var someText = "Some text here to make things happen ;-)";
      var content = GetBytes( someText );

      for(var i=0; i < 100; i++)
      {
         Response.OutputStream.Write(content, 0, content.Length);
      }

      return View();
   }
   catch(HttpException hex)
   {
      if (hex.Message.StartsWith("The remote host closed the connection. The error code is 0x800704CD."))
            {
                //react on remote host closed the connection exception.
                var msg = hex.Message;
            }  
   }
   catch(Exception somethingElseHappened)
   {
      //handle it with some other code
   }

   return View();
} 

Now run the website in debug mode. Put a breakpoint in the loop that writes to the output stream. Go to that action method and after the first iteration passed close the tab of the browser. Hit F10 to continue the loop. After it hit the next iteration you will see the exception. Enjoy your exception :-)

Assignment in bash scripts cannot have spaces around the = and you probably want your date commands enclosed in backticks $():

#!/bin/bash
folder="ABC"
useracct='test'
day=$(date "+%d")
month=$(date "+%B")
year=$(date "+%Y")
folderToBeMoved="/users/$useracct/Documents/Archive/Primetime.eyetv"
newfoldername="/Volumes/Media/Network/$folder/$month$day$year"
ECHO "Network is $network" $network
ECHO "day is $day"
ECHO "Month is $month"
ECHO "YEAR is $year"
ECHO "source is $folderToBeMoved"
ECHO "dest is $newfoldername"
mkdir $newfoldername
cp -R $folderToBeMoved $newfoldername
if [-f $newfoldername/Primetime.eyetv]; then rm $folderToBeMoved; fi

With the last three lines commented out, for me this outputs:

Network is 
day is 16
Month is March
YEAR is 2010
source is /users/test/Documents/Archive/Primetime.eyetv
dest is /Volumes/Media/Network/ABC/March162010

If it helps anyone, I tried everything above (https w/token mode) - and still nothing was working. I got no errors, but nothing would be installed in node_modules or package_lock.json. If I changed the token or any letter in the repo name or user name, etc. - I'd get an error. So I knew I had the right token and repo name.

I finally realized it's because the name of the dependency I had in my package.json didn't match the name in the package.json of the repo I was trying to pull. Even npm install --verbose doesn't say there's any problem. It just seems to ignore the dependency w/o error.

I had the same problem but I was using a reverse proxy.

So I had to set

client_max_body_size 50m; 

inside both configure files :

• on the gitlab nginx web server (as said inside the previous answers)
• but also on the nginx reverse proxy hosted on the dedicated server.

if params[:pid] is a string, which if it came from a form, it is, you'll probably need to use

For anybody just now hitting this question, and not being able to fix margin: 0 auto, here's something I discovered you may find useful: a table element with no specified width must have display: table and not display: block in order for margin: auto to do work. This may be obvious to some, as the combination of display: block and the default width value will give a table which expands to fill its container, but if you want the table to take it's "natural" width and be centered, you need display: table

Use qsort() in <stdlib.h>.

@paxdiablo The qsort() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

Angular has an orderBy filter that can be used like this:

<select ng-model="selected" ng-options="f.name for f in friends | orderBy:'name'"></select>

See this fiddle for an example.

It's worth noting that if track by is being used it needs to appear after the orderBy filter, like this:

<select ng-model="selected" ng-options="f.name for f in friends | orderBy:'name' track by f.id"></select>

@DawidDrozd's answer above is excellent.

I would add one point. Recent versions of the Clang compiler complain about requiring a "bridging cast" if attempting to use his code.

This seems reasonable: using a trampoline creates a potential bug: since Objective-C classes are reference counted, if we pass their address around as a void *, we risk having a hanging pointer if the class is garbage collected up while the callback is still active.

Solution 1) Cocoa provides CFBridgingRetain and CFBridgingRelease macro functions which presumably add and subtract one from the reference count of the Objective-C object. We should therefore be careful with multiple callbacks, to release the same number of times as we retain.

// C++ Module
#include <functional>

void cppFnRequiringCallback(std::function<void(void)> callback) {
        callback();
}

//Objective-C Module
#import "CppFnRequiringCallback.h"

@interface MyObj : NSObject
- (void) callCppFunction;
- (void) myCallbackFn;
@end

void cppTrampoline(const void *caller) {
        id callerObjC = CFBridgingRelease(caller);
        [callerObjC myCallbackFn];
}

@implementation MyObj
- (void) callCppFunction {
        auto callback = [self]() {
                const void *caller = CFBridgingRetain(self);
                cppTrampoline(caller);
        };
        cppFnRequiringCallback(callback);
}

- (void) myCallbackFn {
    NSLog(@"Received callback.");
}
@end

Solution 2) The alternative is to use the equivalent of a weak reference (ie. no change to the retain count), without any additional safety.

The Objective-C language provides the __bridge cast qualifier to do this (CFBridgingRetain and CFBridgingRelease seem to be thin Cocoa wrappers over the Objective-C language constructs __bridge_retained and release respectively, but Cocoa does not appear to have an equivalent for __bridge).

The required changes are:

void cppTrampoline(void *caller) {
        id callerObjC = (__bridge id)caller;
        [callerObjC myCallbackFn];
}

- (void) callCppFunction {
        auto callback = [self]() {
                void *caller = (__bridge void *)self;
                cppTrampoline(caller);
        };
        cppFunctionRequiringCallback(callback);
}

Try Following

Update A a, B b, SET a.column1=b.column1 where b.id=1

EDITED:- Update more than one column

Update A a, B b, SET a.column1=b.column1, a.column2=b.column2 where b.id=1

You can do:

super.alphaMethod1();

Note, that super is a reference to the parent, but super() is it's constructor.

Use this CSS:

color: red;

that's all.

Install Mylyn connector for GitHub from this update site, it provides great integration: you can directly import your repositories using Import > Projects from Git > GitHub. You can set the default repository folder in Preferences > Git.

Run:

in Ubuntu/linux

 sudo rm /var/www/html/rails/WBPOCTEST/tmp/pids/server.pid

Or

 pkill -9 ruby

or

lsof -wni tcp:3000

kill -9 pid

I would suggest a slight change in your logic. It may or may not work, depending on what you need to accomplish.

handle_event() can still do the "boring default code" but instead of being virtual, at the point where you want it to do the "new exciting code" have the base class call an abstract method (i.e. must-be-overridden) method that will be supplied by your descendant class.

EDIT: And if you later decide that some of your descendant classes do not need to provide "new exciting code" then you can change the abstract to virtual and supply an empty base class implementation of that "inserted" functionality.

Re: aku, izb, John Topley...

Watch out for mutability issues...

It may seem sensible to omit getters/setters. It actually may be ok in some cases. The real problem with the proposed pattern shown here is mutability.

The problem is once you pass an object reference out containing non-final, public fields. Anything else with that reference is free to modify those fields. You no longer have any control over the state of that object. (Think what would happen if Strings were mutable.)

It gets bad when that object is an important part of the internal state of another, you've just exposed internal implementation. To prevent this, a copy of the object must be returned instead. This works, but can cause massive GC pressure from tons of single-use copies created.

If you have public fields, consider making the class read-only. Add the fields as parameters to the constructor, and mark the fields final. Otherwise make sure you're not exposing internal state, and if you need to construct new instances for a return value, make sure it won't be called excessively.

See: "Effective Java" by Joshua Bloch -- Item #13: Favor Immutability.

PS: Also keep in mind, all JVMs these days will optimize away the getMethod if possible, resulting in just a single field-read instruction.

Code that calls COM object dlls (for example, to read proprietary data files), may work fine in a user interface but hang mysteriously from a service. The reason is that as of .Net 2.0 user interfaces assume STA (thread-safe) while services assume MTA ((before that, services assumed STA). Having to create an STA thread for every COM call in a service can add significant overhead.

It doesn't recognize that you have a master branch, but I found a way to get around it. I found out that there's nothing special about a master branch, you can just create another branch and call it master branch and that's what I did.

To create a master branch:

git checkout -b master

And you can work off of that.

I find the best (and least frustrating) path is to start with Allow from All, then, when you know it will work that way, scale it back to the more secure Allow from 127.0.0.1 or Allow from ::1 (localhost).

As long as your firewall is configured properly, Allow from all shouldn't cause any problems, but it is better to only allow from localhost if you don't need other computers to be able to access your site.

Don't forget to restart Apache whenever you make changes to httpd.conf. They will not take effect until the next start.

Hopefully this is enough to get you started, there is lots of documentation available online.

It depends on the problem.

Adjacency Matrix

• Uses O(n^2) memory
• It is fast to lookup and check for presence or absence of a specific edge
  between any two nodes O(1)
• It is slow to iterate over all edges
• It is slow to add/delete a node; a complex operation O(n^2)
• It is fast to add a new edge O(1)

Adjacency List

• Memory usage depends on the number of edges (not number of nodes),
  which might save a lot of memory if the adjacency matrix is sparse
• Finding the presence or absence of specific edge between any two nodes
  is slightly slower than with the matrix O(k); where k is the number of neighbors nodes
• It is fast to iterate over all edges because you can access any node neighbors directly
• It is fast to add/delete a node; easier than the matrix representation
• It fast to add a new edge O(1)

@page margin:0mm now works in Firefox 19.0a2 (2012-12-07).

In Java, a String is a reference to heap-allocated storage. Returning "ans" only returns the reference so there is no need for stack-allocated storage. In fact, there is no way in Java to allocate objects in stack storage.

I would change to this, though. You don't need "ans" at all.

return String.format("%d:%d", mins, secs);

Really easy & gr8 approach :

• First create your splash with the following website :

  https://www.norio.be/android-feature-graphic-generator/

  Choose your logo and slogan, choose your beautiful background. resize it to 4096x4096.

• Now download that picture and uplodate it to :

  https://apetools.webprofusion.com/app/#/tools/imagegorilla

  And generate all the splash screens needed, all devices, all platforms.

Enjoy!

There are enough answers here that will help with the implementation. this post was meant to help others with the first step of creating the splash screen!

In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.

Example:

select * from table order by [some_column] 
offset 10 rows
FETCH NEXT 10 rows only

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

I've used a top rated answer from this page many times, but while learning React, i've found a better way to do that, without binding and without inline function inside props.

Just look here:

class Parent extends React.Component {

  constructor() {
    super();
    this.state={
      someVar: value
    }
  }

  handleChange=(someValue)=>{
    this.setState({someVar: someValue})
  }

  render() {
    return <Child handler={this.handleChange} />
  }

}

export const Child = ({handler}) => {
  return <Button onClick={handler} />
}

The key is in an arrow function:

handleChange=(someValue)=>{
  this.setState({someVar: someValue})
}

View.GONE makes the view invisible without the view taking up space in the layout. View.INVISIBLE makes the view just invisible still taking up space.

You are first using GONE and then INVISIBLE on the same view.Since, the code is executed sequentially, first the view becomes GONE then it is overridden by the INVISIBLE type still taking up space.

You should add button listener on the button and inside the onClick() method make the views visible. This should be the logic according to me in your onCreate() method.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_setting);

    final DatePicker dp2 = (DatePicker) findViewById(R.id.datePick2);
    final Button btn2 = (Button) findViewById(R.id.btnDate2);
    final Button btn3 = (Button) findViewById(R.id.btnVisibility);

    dp2.setVisibility(View.INVISIBLE);
    btn2.setVisibility(View.INVISIBLE);

    bt3.setOnClickListener(new View.OnCLickListener(){ 
    @Override
    public void onClick(View view)
    {
        dp2.setVisibility(View.VISIBLE);
        bt2.setVisibility(View.VISIBLE);
    }
  });
}

I think this should work easily. Hope this helps.

If you are using Eloquent, in your model put:

public function getPriceAttribute($price)
{
    return $this->attributes['price'] = sprintf('U$ %s', number_format($price, 2));
}

Where getPriceAttribute is your field on database. getSomethingAttribute.

This is my Save Attachments script. You select all the messages that you want the attachments saved from, and it will save a copy there.

This answer is not the answer for the above mentioned question but it is related to same topic and might be useful for people searching for same error.

I faced the same error when I executed below mentioned query.

select OR.* from ORDER_REL_STAT OR

problem with above query was OR is keyword so it was expecting other values when I replaced with some other alias it worked fine.

This did it for me: (10 years later)

git log [--remotes] --no-walk --decorate

Since there is no stored information on branch creation times, what this does is display the first commit of each branch (--no-walk), which includes the date of the commit. Use --remotes for the remote branches, or omit it for local branches.

Since I do at least one commit in a branch before creating another one, this permitted me trace back a few months of branch creations (and feature dev-start) for documentation purposes.

This code works for me:

Dim script As String = "<script type=""text/javascript"">window.open('" & URL.ToString & "');</script>"
ClientScript.RegisterStartupScript(Me.GetType, "openWindow", script)

The best solution is to change buildDir in build.gradle:

For example:

allprojects {
    buildDir = "C:/tmp/${rootProject.name}/${project.name}"
    repositories {
        jcenter()
    }
}

Rebuild and happy coding.

error 'Class' does not name a type

Just in case someone does the same idiotic thing I did ... I was creating a small test program from scratch and I typed Class instead of class (with a small C). I didn't take any notice of the quotes in the error message and spent a little too long not understanding my problem.

My search for a solution brought me here so I guess the same could happen to someone else.

I think this issue is similar to mine:

1. Connect to MySQL
2. End MySQL service (should not quit node script)
3. Start MySQL service, Node reconnects to MySQL
4. Query the DB -> FAIL (Cannot enqueue Query after fatal error.)

I solved this issue by recreating a new connection with the use of promises (q).

mysql-con.js

'use strict';
var config          = require('./../config.js');
var colors          = require('colors');
var mysql           = require('mysql');
var q               = require('q');
var MySQLConnection = {};

MySQLConnection.connect = function(){
    var d = q.defer();
    MySQLConnection.connection = mysql.createConnection({
        host                : 'localhost',
        user                : 'root',
        password            : 'password',
        database            : 'database'
    });

    MySQLConnection.connection.connect(function (err) {
        if(err) {
            console.log('Not connected '.red, err.toString().red, ' RETRYING...'.blue);
            d.reject();
        } else {
            console.log('Connected to Mysql. Exporting..'.blue);
            d.resolve(MySQLConnection.connection);
        }
    });
    return d.promise;
};

module.exports = MySQLConnection;

mysqlAPI.js

var colors          = require('colors');
var mysqlCon        = require('./mysql-con.js');
mysqlCon.connect().then(function(con){
   console.log('connected!');
    mysql = con;
    mysql.on('error', function (err, result) {
        console.log('error occurred. Reconneting...'.purple);
        mysqlAPI.reconnect();
    });
    mysql.query('SELECT 1 + 1 AS solution', function (err, results) {
            if(err) console.log('err',err);
            console.log('Works bro ',results);
    });
});

mysqlAPI.reconnect = function(){
    mysqlCon.connect().then(function(con){
      console.log("connected. getting new reference");
        mysql = con;
        mysql.on('error', function (err, result) {
            mysqlAPI.reconnect();
        });
    }, function (error) {
      console.log("try again");
        setTimeout(mysqlAPI.reconnect, 2000);
    });
};

I hope this helps.

With Spring Data Jpa, we can use this method:

    /*
     * (non-Javadoc)
     * @see org.springframework.data.jpa.repository.JpaSpecificationExecutor#count(org.springframework.data.jpa.domain.Specification)
     */
    @Override
    public long count(@Nullable Specification<T> spec) {
        return executeCountQuery(getCountQuery(spec, getDomainClass()));
    }

If you are a windows user and your android sdk is located at C:\Users\%username%\AppData\Local\Android\Sdk then you can follow this method. If your andoid sdk not located there, replace that path to the below code.

@echo off
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" disconnect
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" shell ip route > %temp%\addrs12321.txt
For /F "UseBackQ Delims==" %%A In ("%temp%\addrs12321.txt") Do Set "lastline=%%A"
FOR %%C IN (%lastline%) DO SET last=%%C
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" tcpip 5555
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" connect %last%:5555 > %temp%\adbresult.txt
set /p result=<%temp%\adbresult.txt
del /f %temp%\addrs12321.txt
echo MSGBOX "%result%" > %temp%\TEMPmessage.vbs
call %temp%\TEMPmessage.vbs
del %temp%\TEMPmessage.vbs /f /q
del %temp%\adbresult.txt /f /q

Step 1.

1. Turn on usb debugging,
2. Connect your phone to windows machine
3. select file transfer in usb options menu in android menu (if found)

Step 2.

1. copy above code

2. save as its extension like .bat, eg filename.bat

3. double click on the file you saved. done

note you can connect any time by running that file while the device being connected with the pc with usb debugging is turned on.

Always use parseInt with a radix (base) as the second parameter, or you will get unexpected results:

var number = parseInt($(this).find('.number').text(), 10);

A popular variation however is to use + as a unitary operator. This will always convert with base 10 and never throw an error, just return zero NaN which can be tested with the function isNaN() if it's an invalid number:

var number = +($(this).find('.number').text());

<input type='text' 
       name='t1'
       id='t1'
       maxlength=10
       placeholder='typing some text' >
<p></p>

This is the text box, it has a fixed length of 10 characters, and if you can try but this text box does not contain maximum length 10 character

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

This problem is due to private key in the certificate in your profile not match that in your keychain. I resolve this by

1. delete all iPhone Developer certificate in keychain.
2. delete all certificate in apple account.
3. using xcode "Manage Certificates" to add certificate, sometime you still have certificate in your Mac, but I do not know where it is for now, and if added successfully, your apple account will display that certificate too, and then you can create your profile with that certificate and download ... goto 5
4. if you use "Manage Certificates" can't add certificate, you can create a new certificate, and do remain steps.
5. finish.

same answer with Code signing issue in Xcode version 8.

you can call INSERTED, SQL Server uses these tables to capture the data of the modified row before and after the event occurs.I assume in your table the name of the key is Id

I think the following code can help you

CREATE TRIGGER [dbo].[after_update]
ON [dbo].[MYTABLE]
   AFTER UPDATE
AS
BEGIN
    UPDATE dbo.[MYTABLE]
    SET    dbo.[MYTABLE].CHANGED_ON = GETDATE(),
           dbo.[MYTABLE].CHANGED_BY = USER_NAME(USER_ID())
    FROM   INSERTED
    WHERE  INSERTED.Id = dbo.[MYTABLE].[Id]
END

A simple solution is to make the scope variable object. Then access the content with {{ whatever-object.whatever-property }}. The variable is not updating because JavaScript pass Primitive type by value. Whereas Object are passed by reference which solves the problem.

The regex provided should match any url of the form http://www.ietf.org/rfc/rfc3986.txt; and does when tested in the python interpreter.

What format have the URLs you've been having trouble parsing had?

Create the intent like this:

Intent smsIntent = new Intent(android.content.Intent.ACTION_VIEW);
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address","your desired phoneNumber");         
smsIntent.putExtra("sms_body","your desired message");
smsIntent.setFlags(android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(smsIntent);

If you just have included a layout file at the beginning of onCreate() inside setContentView and want to get this layout to add new elements programmatically try this:

ViewGroup linearLayout = (ViewGroup) findViewById(R.id.linearLayoutID);

then you can create a new Button for example and just add it:

Button bt = new Button(this);
bt.setText("A Button");
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 
                                    LayoutParams.WRAP_CONTENT));
linerLayout.addView(bt);

try this

Jobs

select s.name,l.name
 from  msdb..sysjobs s 
 left join master.sys.syslogins l on s.owner_sid = l.sid

Packages

select s.name,l.name 
from msdb..sysssispackages s 
 left join master.sys.syslogins l on s.ownersid = l.sid

My solution was. Create a FUNCTION calling PROCEDURE.

So, inside JAVA code you execute a NATIVE QUERY calling the oracle FUNCTION.

FLAG_ACTIVITY_NO_HISTORY when starting the activity you wish to finish after the user goes to another one.

I ran this on MacOS /Applications/Python\ 3.6/Install\ Certificates.command

$array = explode(' ', $string);

I use this solution:

It's a bit more concise since I use: ng-repeat="obj in objects | filter : paginate" to filter the rows. Also made it working with $resource:

If you are developing an OSGi system I would recommend you to download the "bundlefied" version from Springsource Enterprise Bundle Repository.

Otherwise its ok to use a regular jar-file containing the javax.persistence package

Yes, from the moment on you establish a HTTPS connection everyting is secure. The query string (GET) as the POST is sent over SSL.

You can also use a proxy tool like Charles to capture the outgoing request headers, data, etc. by passing the proxy details through CURLOPT_PROXY to your curl_setopt_array method.

For example:

$proxy = '127.0.0.1:8888';
$opt = array (
    CURLOPT_URL => "http://www.example.com",
    CURLOPT_PROXY => $proxy,
    CURLOPT_POST => true,
    CURLOPT_VERBOSE => true,
    );

$ch = curl_init();
curl_setopt_array($ch, $opt);
curl_exec($ch);
curl_close($ch);

I think this is better, following the good practices of passing parameters to the query:

BookingDates::whereRaw('email = ? or name like ?', [$request->email,"%{$request->name}%"])->get();

You can see it in the documentation, Laravel 5.5.

You can also use the Laravel scout and make it easier with search. Here is the documentation.

The example below includes scrolling behaviour if the content of the expanded centre component extends past its bounds. Also the centre component takes 100% of remaining space in the viewport.

jsfiddle here

html, body, .r_flex_container{
    height: 100%;
    display: flex;
    flex-direction: column;
    background: red;
    margin: 0;
}
.r_flex_container {
    display:flex;
    flex-flow: column nowrap;
    background-color:blue;
}

.r_flex_fixed_child {
    flex:none;
    background-color:black;
    color:white;

}
.r_flex_expand_child {
    flex:auto;
    background-color:yellow;
    overflow-y:scroll;
}

Example of html that can be used to demonstrate this behaviour

<html>
<body>
    <div class="r_flex_container">
      <div class="r_flex_fixed_child">
        <p> This is the fixed 'header' child of the flex container </p>
      </div>
      <div class="r_flex_expand_child">
            <article>this child container expands to use all of the space given to it -  but could be shared with other expanding childs in which case they would get equal space after the fixed container space is allocated.

You will want to look into the nl2br() function along with the trim().

The nl2br() will insert <br /> before the newline character (\n) and the trim() will remove any ending \n or whitespace characters.

$text = trim($_POST['textareaname']); // remove the last \n or whitespace character
$text = nl2br($text); // insert <br /> before \n 

That should do what you want.

UPDATE

The reason the following code will not work is because in order for \n to be recognized, it needs to be inside double quotes since double quotes parse data inside of them, where as single quotes takes it literally, IE "\n"

$text = str_replace('\n', '<br />', $text);

To fix it, it would be:

$text = str_replace("\n", '<br />', $text);

But it is still better to use the builtin nl2br() function, PHP provides.

EDIT

Sorry, I figured the first question was so you could add the linebreaks in, indeed this will change the answer quite a bit, as anytype of explode() will remove the line breaks, but here it is:

$text = trim($_POST['textareaname']);
$textAr = explode("\n", $text);
$textAr = array_filter($textAr, 'trim'); // remove any extra \r characters left behind

foreach ($textAr as $line) {
    // processing here. 
} 

If you do it this way, you will need to append the <br /> onto the end of the line before the processing is done on your own, as the explode() function will remove the \n characters.

Added the array_filter() to trim() off any extra \r characters that may have been lingering.

simple way to do maxlength for textarea in html4 is:

<textarea cols="60" rows="5" onkeypress="if (this.value.length > 100) { return false; }"></textarea>

Change the "100" to however many characters you want

Use a .gitignore file. This allows you to ignore certain files. http://git-scm.com/docs/gitignore

Here's an example Eclipse one, which handles your classpath and project files: https://github.com/github/gitignore/blob/master/Global/Eclipse.gitignore

int[] anArray = { 1, 5, 2, 7 };
// Finding max
int m = anArray.Max();

// Positioning max
int p = Array.IndexOf(anArray, m);

Supply the public rsa key of the host :-

String knownHostPublicKey = "mywebsite.com ssh-rsa AAAAB3NzaC1.....XL4Jpmp/";

session.setKnownHosts(new ByteArrayInputStream(knownHostPublicKey.getBytes()));

The solution that worked for me is by calling the 'material_select' function after the options data has been loaded. If you print out the value of OptionsList.find().count() to the console it's first 0 then a few milliseconds later the list gets populated with data.

Template.[name].rendered = function() {
    this.autorun(function() {
        var optionsCursor = OptionsList.find().count();
        if(optionsCursor > 0)
        {
            $('select').material_select();
        }
    });
};

Suppose we haven't used the "@" operator then our code would look like this:

$fileHandle = fopen($fileName, $writeAttributes);

And what if the file we are trying to open is not found? It will show an error message.

To suppress the error message we are using the "@" operator like:

$fileHandle = @fopen($fileName, $writeAttributes);

The second form (creating an HTTP server yourself, instead of having Express create one for you) is useful if you want to reuse the HTTP server, for example to run socket.io within the same HTTP server instance:

var express = require('express');
var app     = express();
var server  = require('http').createServer(app);
var io      = require('socket.io').listen(server);
...
server.listen(1234);

However, app.listen() also returns the HTTP server instance, so with a bit of rewriting you can achieve something similar without creating an HTTP server yourself:

var express   = require('express');
var app       = express();

// app.use/routes/etc...

var server    = app.listen(3033);
var io        = require('socket.io').listen(server);

io.sockets.on('connection', function (socket) {
  ...
});

Use range() instead, like the following :

for i in range(len(words)):
    ...

import binascii

x = b'test'

This code contains examples for converting ASCII characters to and from hexadecimal. In your situation, the line you'd want to use is str(binascii.hexlify(c),'ascii').

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

The NVARCHAR2 datatype was introduced by Oracle for databases that want to use Unicode for some columns while keeping another character set for the rest of the database (which uses VARCHAR2). The NVARCHAR2 is a Unicode-only datatype.

One reason you may want to use NVARCHAR2 might be that your DB uses a non-Unicode character set and you still want to be able to store Unicode data for some columns without changing the primary character set. Another reason might be that you want to use two Unicode character set (AL32UTF8 for data that comes mostly from western Europe, AL16UTF16 for data that comes mostly from Asia for example) because different character sets won't store the same data equally efficiently.

Both columns in your example (Unicode VARCHAR2(10 CHAR) and NVARCHAR2(10)) would be able to store the same data, however the byte storage will be different. Some strings may be stored more efficiently in one or the other.

Note also that some features won't work with NVARCHAR2, see this SO question:

• Oracle Text will not work with NVARCHAR2. What else might be unavailable?

When you say you increased MAVEN_OPTS, what values did you increase? Did you increase the MaxPermSize, as in example:

export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"

(or on Windows:)

set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=128m

You can also specify these JVM options in each maven project separately.

You can use WMI to get CPU percentage information. You can even log into a remote computer if you have the correct permissions. Look at http://www.csharphelp.com/archives2/archive334.html to get an idea of what you can accomplish.

Also helpful might be the MSDN reference for the Win32_Process namespace.

See also a CodeProject example How To: (Almost) Everything In WMI via C#.

Use the button for the add maven projects and go inside the folder of the project. Then, select the pom.xml file and add them in the IntelliJ.

Please try CURRENT_TIME() or now() functions

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', NOW(), '$comments')"

OR

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', CURRENT_TIME(), '$comments')"

OR you could try with PHP date function here:

$date = date("Y-m-d H:i:s");

You can also do it in one row:

if (MessageBox.Show("Text", "Title", MessageBoxButtons.YesNo) == DialogResult.Yes)

And if you want to show a messagebox on top:

if (MessageBox.Show(new Form() { TopMost = true }, "Text", "Text", MessageBoxButtons.YesNo) == DialogResult.Yes)

Updated Answer

Updating because I noticed it's an active answer, however Flexbox would be the correct approach now.

Live Demo

Vertical and horizontal alignment.

#wrapper {
  display: flex;
  align-items: center;
  justify-content: center;
}

Just horizontal (as long as the main flex axis is horizontal which is default)

#wrapper {
  display: flex;
  justify-content: center;
}

Original Answer using a fixed width and no flexbox

If the original poster wants vertical and center alignment its quite easy for fixed width and height of the button, try the following

Live Demo

CSS

button{
    height:20px; 
    width:100px; 
    margin: -20px -50px; 
    position:relative;
    top:50%; 
    left:50%;
}

for just horizontal alignment use either

button{
    margin: 0 auto;
}

or

div{
    text-align:center;
}

This worked for me! You can convert to datatype you want be it a date or string

to_char(TO_DATE(TO_CHAR(end_date),'MM-DD-YYYY'),'YYYY-MM-DD') AS end_date

Another way that hasn't been mentioned yet is the use of Function.prototype.bind

var funcs = {};_x000D_
for (var i = 0; i < 3; i++) {_x000D_
  funcs[i] = function(x) {_x000D_
    console.log('My value: ' + x);_x000D_
  }.bind(this, i);_x000D_
}_x000D_
for (var j = 0; j < 3; j++) {_x000D_
  funcs[j]();_x000D_
}

UPDATE

As pointed out by @squint and @mekdev, you get better performance by creating the function outside the loop first and then binding the results within the loop.

function log(x) {_x000D_
  console.log('My value: ' + x);_x000D_
}_x000D_
_x000D_
var funcs = [];_x000D_
_x000D_
for (var i = 0; i < 3; i++) {_x000D_
  funcs[i] = log.bind(this, i);_x000D_
}_x000D_
_x000D_
for (var j = 0; j < 3; j++) {_x000D_
  funcs[j]();_x000D_
}

Yes, I can give you the outline but my Python is a bit rusty and I'm too busy to explain in detail.

Basically, you need to put a proxy in the method that will call the original, eg:

 class fred(object):
   def blog(self):
     print "We Blog"


 class methCallLogger(object):
   def __init__(self, meth):
     self.meth = meth

   def __call__(self, code=None):
     self.meth()
     # would also log the fact that it invoked the method

 #example
 f = fred()
 f.blog = methCallLogger(f.blog)

This StackOverflow answer about callable may help you understand the above.

In more detail:

Although the answer was accepted, due to the interesting discussion with Glenn and having a few minutes free, I wanted to enlarge on my answer:

# helper class defined elsewhere
class methCallLogger(object):
   def __init__(self, meth):
     self.meth = meth
     self.was_called = False

   def __call__(self, code=None):
     self.meth()
     self.was_called = True

#example
class fred(object):
   def blog(self):
     print "We Blog"

f = fred()
g = fred()
f.blog = methCallLogger(f.blog)
g.blog = methCallLogger(g.blog)
f.blog()
assert(f.blog.was_called)
assert(not g.blog.was_called)

All those settings are necessary to choose which tags you are interested in, but in order to display these tags in a list, you also need to select the right Eclipse perspective. I finally discovered that the "Markers" tab containing the "Task" list is only available under the "Java EE" perspective... Hope this helps! :-)

MessageBox::Show uses function from user32.dll, and its style is dependent on Windows, so you cannot change it like that, you have to create your own form

If you go for third party library option, try using Aspose.Cells API that enables Java Applications to create (read/write) and manage Excel spreadsheets efficiently without requiring Microsoft Excel.

e.g

Sample code:

1.

//Load sample workbook
Workbook wb = new Workbook(dirPath + "sample.xlsx");

//Access first worksheet
Worksheet ws = wb.getWorksheets().get(0);

//Access cells iterator
Iterator itrat = ws.getCells().iterator();

//Print cells name in iterator
while(itrat.hasNext())
{
    Cell cell = (Cell)itrat.next();

    System.out.println(cell.getName() + ": " + cell.getStringValue().trim());
}

Workbook book = new Workbook("sample.xlsx");
Worksheet sheet = book.getWorksheets().get(0);
Range range = sheet.getCells().getMaxDisplayRange();//You may also create your desired range (in the worksheet) using, e.g sheet.getCells().createRange("A1", "J11");
Iterator rangeIterator = range.iterator();
while(rangeIterator.hasNext())
{
Cell cell = (Cell)rangeIterator.next();
//your code goes here.
}

Hope, this helps a bit.

PS. I am working as Support developer/ Evangelist at Aspose.

Seems like string.Replace should have an overload that takes a StringComparison argument. Since it doesn't, you could try something like this:

public static string ReplaceString(string str, string oldValue, string newValue, StringComparison comparison)
{
    StringBuilder sb = new StringBuilder();

    int previousIndex = 0;
    int index = str.IndexOf(oldValue, comparison);
    while (index != -1)
    {
        sb.Append(str.Substring(previousIndex, index - previousIndex));
        sb.Append(newValue);
        index += oldValue.Length;

        previousIndex = index;
        index = str.IndexOf(oldValue, index, comparison);
    }
    sb.Append(str.Substring(previousIndex));

    return sb.ToString();
}

You can send data through JSON or via normal POST, here is an example for JSON.

 var value1 = 1;
 var value2 = 2;
 var value3 = 3;   
 $.ajax({
      type: "POST",
      contentType: "application/json; charset=utf-8",
      url: "yoururlhere",
      data: { data1: value1, data2: value2, data3: value3 },
      success: function (result) {
           // do something here
      }
 });

If you want to use it via normal post try this

 $.ajax({
      type: "POST",
      url: $('form').attr("action"),   
      data: $('#form0').serialize(),
      success: function (result) {
         // do something here
      }
 });

in xcode 8.2.1 in the interface builder it moves to:

Here's another way to think about it. Suppose there were a name() function that returned the name of its argument. Given the following code:

def f(a):
    return a

b = "x"
c = b
d = f(c)

e = [f(b), f(c), f(d)]

What should name(e[2]) return, and why?

While Alex's answer points us to a good technique, the implementation that he gave runs into a problem when we have nested objects.

class more_info
    string status

class payload
    string action
    string method
    string data
    class more_info

with the below code:

def as_more_info(dct):
    return MoreInfo(dct['status'])

def as_payload(dct):
    return Payload(dct['action'], dct['method'], dct['data'], as_more_info(dct['more_info']))

payload = json.loads(message, object_hook = as_payload)

payload.more_info will also be treated as an instance of payload which will lead to parsing errors.

From the official docs:

object_hook is an optional function that will be called with the result of any object literal decoded (a dict). The return value of object_hook will be used instead of the dict.

Hence, I would prefer to propose the following solution instead:

class MoreInfo(object):
    def __init__(self, status):
        self.status = status

    @staticmethod
    def fromJson(mapping):
        if mapping is None:
            return None

        return MoreInfo(
            mapping.get('status')
        )

class Payload(object):
    def __init__(self, action, method, data, more_info):
        self.action = action
        self.method = method
        self.data = data
        self.more_info = more_info

    @staticmethod
    def fromJson(mapping):
        if mapping is None:
            return None

        return Payload(
            mapping.get('action'),
            mapping.get('method'),
            mapping.get('data'),
            MoreInfo.fromJson(mapping.get('more_info'))
        )

import json
def toJson(obj, **kwargs):
    return json.dumps(obj, default=lambda j: j.__dict__, **kwargs)

def fromJson(msg, cls, **kwargs):
    return cls.fromJson(json.loads(msg, **kwargs))

info = MoreInfo('ok')
payload = Payload('print', 'onData', 'better_solution', info)
pl_json = toJson(payload)
l1 = fromJson(pl_json, Payload)

function toggling_fields_contact_bank(class_name) {
    jQuery("." + class_name).animate({

}

What is the difference between the list methods append and extend?

• append adds its argument as a single element to the end of a list. The length of the list itself will increase by one.
• extend iterates over its argument adding each element to the list, extending the list. The length of the list will increase by however many elements were in the iterable argument.

append

The list.append method appends an object to the end of the list.

my_list.append(object) 

Whatever the object is, whether a number, a string, another list, or something else, it gets added onto the end of my_list as a single entry on the list.

>>> my_list
['foo', 'bar']
>>> my_list.append('baz')
>>> my_list
['foo', 'bar', 'baz']

So keep in mind that a list is an object. If you append another list onto a list, the first list will be a single object at the end of the list (which may not be what you want):

>>> another_list = [1, 2, 3]
>>> my_list.append(another_list)
>>> my_list
['foo', 'bar', 'baz', [1, 2, 3]]
                     #^^^^^^^^^--- single item at the end of the list.

extend

The list.extend method extends a list by appending elements from an iterable:

my_list.extend(iterable)

So with extend, each element of the iterable gets appended onto the list. For example:

>>> my_list
['foo', 'bar']
>>> another_list = [1, 2, 3]
>>> my_list.extend(another_list)
>>> my_list
['foo', 'bar', 1, 2, 3]

Keep in mind that a string is an iterable, so if you extend a list with a string, you'll append each character as you iterate over the string (which may not be what you want):

>>> my_list.extend('baz')
>>> my_list
['foo', 'bar', 1, 2, 3, 'b', 'a', 'z']

Operator Overload, __add__ (+) and __iadd__ (+=)

Both + and += operators are defined for list. They are semantically similar to extend.

my_list + another_list creates a third list in memory, so you can return the result of it, but it requires that the second iterable be a list.

my_list += another_list modifies the list in-place (it is the in-place operator, and lists are mutable objects, as we've seen) so it does not create a new list. It also works like extend, in that the second iterable can be any kind of iterable.

Don't get confused - my_list = my_list + another_list is not equivalent to += - it gives you a brand new list assigned to my_list.

Time Complexity

Append has constant time complexity, O(1).

Extend has time complexity, O(k).

Iterating through the multiple calls to append adds to the complexity, making it equivalent to that of extend, and since extend's iteration is implemented in C, it will always be faster if you intend to append successive items from an iterable onto a list.

Performance

You may wonder what is more performant, since append can be used to achieve the same outcome as extend. The following functions do the same thing:

def append(alist, iterable):
    for item in iterable:
        alist.append(item)

def extend(alist, iterable):
    alist.extend(iterable)

So let's time them:

import timeit

>>> min(timeit.repeat(lambda: append([], "abcdefghijklmnopqrstuvwxyz")))
2.867846965789795
>>> min(timeit.repeat(lambda: extend([], "abcdefghijklmnopqrstuvwxyz")))
0.8060121536254883

Addressing a comment on timings

A commenter said:

Perfect answer, I just miss the timing of comparing adding only one element

Do the semantically correct thing. If you want to append all elements in an iterable, use extend. If you're just adding one element, use append.

Ok, so let's create an experiment to see how this works out in time:

def append_one(a_list, element):
    a_list.append(element)

def extend_one(a_list, element):
    """creating a new list is semantically the most direct
    way to create an iterable to give to extend"""
    a_list.extend([element])

import timeit

And we see that going out of our way to create an iterable just to use extend is a (minor) waste of time:

>>> min(timeit.repeat(lambda: append_one([], 0)))
0.2082819009956438
>>> min(timeit.repeat(lambda: extend_one([], 0)))
0.2397019260097295

We learn from this that there's nothing gained from using extend when we have only one element to append.

Also, these timings are not that important. I am just showing them to make the point that, in Python, doing the semantically correct thing is doing things the Right Way™.

It's conceivable that you might test timings on two comparable operations and get an ambiguous or inverse result. Just focus on doing the semantically correct thing.

Conclusion

We see that extend is semantically clearer, and that it can run much faster than append, when you intend to append each element in an iterable to a list.

If you only have a single element (not in an iterable) to add to the list, use append.

Suppose

a = ['a', 'b', 'c', 3, 4, 'd', 6, 7, 8]

and the list of indexes is stored in

b= [0, 1, 2, 4, 6, 7, 8]

then a simple one-line solution will be

c = [a[i] for i in b]

I know this is an old thread. But with symfony 3.3 I did this:

{{ render(controller(
    'AppBundle\\Controller\\yourController::yourAction'
)) }}

Another option...

To make this works

docker run -d --rm $IMG_NAME "bash:command1&&command2&&command3"

in dockerfile

ENTRYPOINT ["/entrypoint.sh"]

in entrypoint.sh

#!/bin/sh

entrypoint_params=$1
printf "==>[entrypoint.sh] %s\n" "entry_point_param is $entrypoint_params"

PARAM1=$(echo $entrypoint_params | cut -d':' -f1) # output is 1 must be 'bash' it     will be tested    
PARAM2=$(echo $entrypoint_params | cut -d':' -f2) # the real command separated by     &&

printf "==>[entrypoint.sh] %s\n" "PARAM1=$PARAM1"
printf "==>[entrypoint.sh] %s\n" "PARAM2=$PARAM2"

if [ "$PARAM1" = "bash" ];
then
    printf "==>[entrypoint.sh] %s\n" "about to running $PARAM2 command"
    echo $PARAM2 | tr '&&' '\n' | while read cmd; do
        $cmd
    done    
fi

In my case (I'm using typescript) I was trying to simulate response with fake data where the data is assigned later on. My first attempt was with:

let response = {status: 200, data: []};

and later, on the assignment of the fake data it starts complaining that it is not assignable to type 'never[]'. Then I defined the response like follows and it accepted it..

let dataArr: MyClass[] = [];
let response = {status: 200, data: dataArr};

and assigning of the fake data:

response.data = fakeData;

set -x will give you what you want.

Here is an example shell script to demonstrate:

#!/bin/bash
set -x #echo on

ls $PWD

This expands all variables and prints the full commands before output of the command.

Output:

+ ls /home/user/
file1.txt file2.txt

The keyword "Selection" is already a vba Range object so you can use it directly, and you don't have to select cells to copy, for example you can be on Sheet1 and issue these commands:

ThisWorkbook.worksheets("sheet2").Range("namedRange_or_address").Copy
ThisWorkbook.worksheets("sheet1").Range("namedRange_or_address").Paste

If it is a multiple selection you should use the Area object in a for loop:

Dim a as Range
For Each a in ActiveSheet.Selection.Areas
    a.Copy
    ThisWorkbook.worksheets("sheet2").Range("A1").Paste
Next

You need to do this:

var scope = {
     splitterStyle: {
         height: 100
     }
};

And then apply this styling to the required elements:

<div id="horizontal" style={splitterStyle}>

In your code you are doing this (which is incorrect):

<div id="horizontal" style={height}>

Where height = 100.

I don't like the auto-commit that git revert does, so this might be helpful for some.

If you just want the modified files not the auto-commit, you can use --no-commit

% git revert --no-commit <commit hash>

which is the same as the -n

% git revert -n <commit hash>

You can use [ScriptIgnore]:

public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    [ScriptIgnore]
    public bool IsComplete
    {
        get { return Id > 0 && !string.IsNullOrEmpty(Name); }
    }
}

Reference here

In this case the Id and then name will only be serialized

You can use

call script.bat

or just

script.bat
