writexl, without Java requirement:

# install.packages("writexl")
library(writexl)
tempfile <- write_xlsx(iris)

for column in df:
    print(df[column])

Have you tried setting margin on the div? e.g.

div {
    padding: 25px, 0
}

for top and bottom. You may also be able to use a percentage:

div {
    padding: 25%, 0
}

function getDashboardSheet(spreadsheet) {
  var sheetName = 'Name';
  return spreadsheet.getSheetByName(sheetName);
}
      var spreadsheet = SpreadsheetApp.openByUrl(SPREADSHEET_URL);  
      var dashboardSheet = getDashboardSheet(spreadsheet);
      Logger.log('see:'+dashboardSheet.getLastRow());

As of Pandas version 0.22, there exists also an alternative to apply: pipe, which can be considerably faster than using apply (you can also check this question for more differences between the two functionalities).

For your example:

df = pd.DataFrame({"my_label": ['A','B','A','C','D','D','E']})

  my_label
0        A
1        B
2        A
3        C
4        D
5        D
6        E

The apply version

df.groupby('my_label').apply(lambda grp: grp.count() / df.shape[0])

gives

          my_label
my_label          
A         0.285714
B         0.142857
C         0.142857
D         0.285714
E         0.142857

and the pipe version

df.groupby('my_label').pipe(lambda grp: grp.size() / grp.size().sum())

yields

my_label
A    0.285714
B    0.142857
C    0.142857
D    0.285714
E    0.142857

So the values are identical, however, the timings differ quite a lot (at least for this small dataframe):

%timeit df.groupby('my_label').apply(lambda grp: grp.count() / df.shape[0])
100 loops, best of 3: 5.52 ms per loop

and

%timeit df.groupby('my_label').pipe(lambda grp: grp.size() / grp.size().sum())
1000 loops, best of 3: 843 µs per loop

Wrapping it into a function is then also straightforward:

def get_perc(grp_obj):
    gr_size = grp_obj.size()
    return gr_size / gr_size.sum()

Now you can call

df.groupby('my_label').pipe(get_perc)

yielding

my_label
A    0.285714
B    0.142857
C    0.142857
D    0.285714
E    0.142857

However, for this particular case, you do not even need a groupby, but you can just use value_counts like this:

df['my_label'].value_counts(sort=False) / df.shape[0]

yielding

A    0.285714
C    0.142857
B    0.142857
E    0.142857
D    0.285714
Name: my_label, dtype: float64

For this small dataframe it is quite fast

%timeit df['my_label'].value_counts(sort=False) / df.shape[0]
1000 loops, best of 3: 770 µs per loop

As pointed out by @anmol, the last statement can also be simplified to

df['my_label'].value_counts(sort=False, normalize=True)

You could recreate the progress bar using CSS3 animations to give it a better look.

Use typeof when you want to get the type at compilation time. Use GetType when you want to get the type at execution time. There are rarely any cases to use is as it does a cast and, in most cases, you end up casting the variable anyway.

There is a fourth option that you haven't considered (especially if you are going to cast an object to the type you find as well); that is to use as.

Foo foo = obj as Foo;

if (foo != null)
    // your code here

This only uses one cast whereas this approach:

if (obj is Foo)
    Foo foo = (Foo)obj;

requires two.

Update (Jan 2020):

• As of C# 7+, you can now cast inline, so the 'is' approach can now be done in one cast as well.

Example:

if(obj is Foo newLocalFoo)
{
    // For example, you can now reference 'newLocalFoo' in this local scope
    Console.WriteLine(newLocalFoo);
}

The following procedure solved my issue:

• Go to your sub-project-module/library-module settings. (press F4 after selecting the module)
• Right Click on Add > Android-Gradle.
• Add build.gradle to your module.

• Add the following script

  buildscript {
  repositories {
      mavenCentral()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:0.6.+'
  }
   }
  
  
    apply plugin: 'android-library'
  
  repositories {
  mavenCentral()
  }
  
  android {
  compileSdkVersion 18
  buildToolsVersion "18.1.0"
  
  defaultConfig {
      minSdkVersion 10
      targetSdkVersion 18
  }
  
  sourceSets {
      main {
          manifest.srcFile 'AndroidManifest.xml'
          java.srcDirs = ['src']
          resources.srcDirs = ['src']
          aidl.srcDirs = ['src']
          renderscript.srcDirs = ['src']
          res.srcDirs = ['res']
          assets.srcDirs = ['assets']
      }
  
  }
     } 
  

  5. add include ':yourModuleName' in your settings.gradle

I think a more reliable way of closing a connection is to tell the sever explicitly to close it in a way compliant with HTTP specification:

HTTP/1.1 defines the "close" connection option for the sender to signal that the connection will be closed after completion of the response. For example,

   Connection: close

in either the request or the response header fields indicates that the connection SHOULD NOT be considered `persistent' (section 8.1) after the current request/response is complete.

The Connection: close header is added to the actual request:

r = requests.post(url=url, data=body, headers={'Connection':'close'})

window.top.location.href = 'index.html';

This will redirect the main window to the index page. Thanks

you can execute javascript from url via events Ex: www.something.com/home/save?id=12<body onload="alert(1)"></body>

does work if params in url are there.

Here is the official documentation of ArrayList.get().

Anyway it is very simple, for example

ArrayList list = new ArrayList();
list.add("1");
list.add("2");
list.add("3");
String str = (String) list.get(0); // here you get "1" in str

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("listfile.txt")
Dim inFile: Set inFile = obj.OpenTextFile("listfile.txt")

' read file
data = inFile.ReadAll
inFile.Close

' write file
outFile.write (data)
outFile.Close

Swift

You should always use the system defaults and not hard coding the font name because the default font could be changed by Apple at any time.

There are a couple of system default fonts(normal, bold, italic) with different sizes(label, button, others):

let font = UIFont.systemFont(ofSize: UIFont.systemFontSize)
let font2 = UIFont.boldSystemFont(ofSize: UIFont.systemFontSize)
let font3 = UIFont.italicSystemFont(ofSize: UIFont.systemFontSize)

beaware that the default font size depends on the target view (label, button, others)

Examples:

let labelFont = UIFont.systemFont(ofSize: UIFont.labelFontSize)
let buttonFont = UIFont.systemFont(ofSize: UIFont.buttonFontSize)
let textFieldFont = UIFont.systemFont(ofSize: UIFont.systemFontSize)

You can try the .delay()

$(".formSentMsg").delay(3200).fadeOut(300);

call the div set the delay time in milliseconds and set the property you want to change, in this case I used .fadeOut() so it could be animated, but you can use .hide() as well.

Try doing this, there's no special character to concatenate in bash :

mystring="${arg1}12${arg2}endoffile"

explanations

If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that's not what you asked) like in the following example :

mystring="$arg112$arg2endoffile"

The brackets are delimiters for the variables when needed. When not needed, you can use it or not.

another solution

$ arg1=foo
$ arg2=bar
$ mystring="$arg1"
$ mystring+="12"
$ mystring+="$arg2"
$ mystring+="endoffile"
$ echo "$mystring"
foo12barendoffile

Cytoscape supports this with its Architecture example which supports dragging elements.

For creating connections, there is the edgehandles extension. It does not yet support editing existing connections. Question.

For editing connection shapes, there is the edge-editing extension. Demo.

The edit-editation extension seems promising, however there is no demo yet.

my two cents about logic:

syntax is "old date" - :"new date", so:

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:00', '2018-11-15 15:00:30')

gives 30,

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:55', '2018-11-15 15:00:15')

gives: -40

There is a method specifically for this purpose:

data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

Use array.push() to add an item to the end of the array.

var sample = new Array();
sample.push(new Object());

To do this n times use a for loop.

var n = 100;
var sample = new Array();
for (var i = 0; i < n; i++)
    sample.push(new Object());

Note that you can also substitute new Array() with [] and new Object() with {} so it becomes:

var n = 100;
var sample = [];
for (var i = 0; i < n; i++)
    sample.push({});

Use Convert.ToDouble(value) rather than (double)value. It takes an object and supports all of the types you asked for! :)

Also, your method is always returning a string in the code above; I'd recommend having the method indicate so, and give it a more obvious name (public string FormatLargeNumber(object value))

You can fade your background-image in various ways since Firefox 4 ...

Your CSS:

.box {
    background: #CCCCCC;
    -webkit-transition: background 0.5s linear;
    -moz-transition: background 0.5s linear;
    -o-transition: background 0.5s linear;
    transition: background 0.5s linear;
    }
.box:hover {
    background: url(path/to/file.png) no-repeat #CCCCCC;
    }

Your XHTML:

<div class="box">
    Some Text …
</div>

And thats it.

If you just want to create a default POM and enable m2eclipse features: so I'm assuming you do not currently have an alternative automated build setup you're trying to import, and I'm assuming you're talking about the m2eclipse plugin.

The m2eclipse plugin provides a right-click option on a project to add this default pom.xml:

Newer M2E versions

Right click on Project -> submenu Configure -> Convert to Maven Project

Older M2E versions

Right click on Project -> submenu Maven -> Enable Dependency Management.

That'll do the necessary to enable the plugin for that project.

To answer 'is there an automatic importer or wizard?': not that I know of. Using the option above will allow you to enable the m2eclipse plugin for your existing project avoiding the manual copying. You will still need to actually set up the dependencies and other stuff you need to build yourself.

Sebastian's answer was the only answer that worked for me while examining a xaml document. If, like me, you'd like a list of all the elements then the method would look a lot like Sebastian's answer above but just returning a list...

    private static List<XElement> GetElements(XDocument doc, string elementName)
    {
        List<XElement> elements = new List<XElement>();

        foreach (XNode node in doc.DescendantNodes())
        {
            if (node is XElement)
            {
                XElement element = (XElement)node;
                if (element.Name.LocalName.Equals(elementName))
                    elements.Add(element);
            }
        }
        return elements;
    }

Call it thus:

var elements = GetElements(xamlFile, "Band");

or in the case of my xaml doc where I wanted all the TextBlocks, call it thus:

var elements = GetElements(xamlFile, "TextBlock");

Simple solution in Swift for iOS 8 with a custom UITableViewCell

override func awakeFromNib() {
    super.awakeFromNib()

    self.layoutMargins = UIEdgeInsetsZero
    self.separatorInset = UIEdgeInsetsZero
}

In this way you are setting layoutMargin and separatorInset just one time instead of doing it for each willDisplayCell as most of the above answers suggest.

If you are using a custom UITableViewCell this is the correct place to do it. Otherwise you should do it in tableView:cellForRowAtIndexPath.

Just another hint: you don't need to set preservesSuperviewLayoutMargins = false because default value is already NO!

Main advantage of <jsp:include /> over <%@ include > is:

<jsp:include /> allows to pass parameters

<jsp:include page="inclusion.jsp">
    <jsp:param name="menu" value="objectValue"/>
</jsp:include>

which is not possible in <%@include file="somefile.jsp" %>

Hibernate uses a ConnectionProvider internally to obtain connections. From the hibernate javadoc:

The ConnectionProvider interface is not intended to be exposed to the application. Instead it is used internally by Hibernate to obtain connections.

The more elegant way of solving this would be to create a database connection pool yourself and hand connections to hibernate and your legacy tool from there.

Maybe

df <- do.call("cbind", list(df, rep(list(NA),length(namevector))))
colnames(df)[-1*(1:(ncol(df) - length(namevector)))] <- namevector

I think style no. 111 (Japan) should work:

SELECT CONVERT(DATETIME, '2012-08-17', 111)

And if that doesn't work for some reason - you could always just strip out the dashes and then you have the totally reliable ISO-8601 format (YYYYMMDD) which works for any language and date format setting in SQL Server:

SELECT CAST(REPLACE('2012-08-17', '-', '') AS DATETIME)

well, why don't you (get rid of sidebar and) squeeze the table so it is without show/hide effect? It looks odd to me now. The table is too robust.
Otherwise I think scunliffe's suggestion should do it. Or if you wish, you can just set the exact width of table and set either percentage or pixel width for table cells.

x86 is a family of backward-compatible instruction set architectures based on the Intel 8086 CPU and its Intel 8088 variant.

An instruction set architecture (ISA) is an abstract model of a computer. It is also referred to as architecture or computer architecture.

A realization of an ISA is called an implementation. An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.

Software that has been written for an ISA can run on different implementations of the same ISA (Exp: 32bit or 64bit). This has enabled binary compatibility between different generations of computers to be easily achieved, and the development of computer families.

Both of these developments have helped to lower the cost of computers and to increase their applicability. For these reasons, the ISA is one of the most important abstractions in computing today.

You're not actually returning anything from your run_cmd function.

function run_cmd(cmd, args, done) {
    var spawn = require("child_process").spawn;
    var child = spawn(cmd, args);
    var result = { stdout: "" };
    child.stdout.on("data", function (data) {
            result.stdout += data;
    });
    child.stdout.on("end", function () {
            done();
    });
    return result;
}

> foo = run_cmd("ls", ["-al"], function () { console.log("done!"); });
{ stdout: '' }
done!
> foo.stdout
'total 28520...'

Works just fine. :)

Use StringIO to turn the read string into a file-like object:

from StringIO import StringIO
import urllib

Image.open(StringIO(urllib.requests.urlopen(url).read()))

Here's some sample code I used recently to do just that.

It opens a workbook, goes down the rows, if a condition is met it writes some data in the row. Finally it saves the modified file.

from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd

START_ROW = 297 # 0 based (subtract 1 from excel row number)
col_age_november = 1
col_summer1 = 2
col_fall1 = 3

rb = open_workbook(file_path,formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy

for row_index in range(START_ROW, r_sheet.nrows):
    age_nov = r_sheet.cell(row_index, col_age_november).value
    if age_nov == 3:
        #If 3, then Combo I 3-4 year old  for both summer1 and fall1
        w_sheet.write(row_index, col_summer1, 'Combo I 3-4 year old')
        w_sheet.write(row_index, col_fall1, 'Combo I 3-4 year old')

wb.save(file_path + '.out' + os.path.splitext(file_path)[-1])

In Xcode 9 there is a new "Actual Size" option. In the Simulator to the Window menu and choose Scale > Actual Size to trigger it. This takes into account your current screen resolution to ensure the on-screen device matches the physical dimensions of a real device.

You can try progress bar instead of seek bar

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="fill_parent"
    android:layout_height="50dp"
    android:layout_marginBottom="35dp"
    />

Both lines are in fact correct but do subtly different things.

The first line creates a new object on the stack by calling a constructor of the format Thing(const char*).

The second one is a bit more complex. It essentially does the following

1. Create an object of type Thing using the constructor Thing(const char*)
2. Create an object of type Thing using the constructor Thing(const Thing&)
3. Call ~Thing() on the object created in step #1

Basic and general difference is:

Fields

• ALWAYS give both get and set access
• CAN NOT cause side effects (throwing exceptions, calling methods, changing fields except the one being got/set, etc)

Properties

• NOT ALWAYS give both get and set access
• CAN cause side effects

I had exactly the same problem, my solution was to use module definition file (.def) instead of __declspec(dllexport) to define exports(http://msdn.microsoft.com/en-us/library/d91k01sh.aspx). I have no idea why this works, but it does

A lock should be considered to use, such as threading.Lock. See lock-objects for more info.

The accepted answer CAN print 10 by thread1, which is not what you want. You can run the following code to understand the bug more easily.

def thread1(threadname):
    while True:
      if a % 2 and not a % 2:
          print "unreachable."

def thread2(threadname):
    global a
    while True:
        a += 1

Using a lock can forbid changing of a while reading more than one time:

def thread1(threadname):
    while True:
      lock_a.acquire()
      if a % 2 and not a % 2:
          print "unreachable."
      lock_a.release()

def thread2(threadname):
    global a
    while True:
        lock_a.acquire()
        a += 1
        lock_a.release()

If thread using the variable for long time, coping it to a local variable first is a good choice.

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem>

How about using some Sass? Here's what I did to achieve something like this (although note that you have to create a Sass list for each of the data-attributes).

/*
  Iterate over list and use "data-social" to put in the appropriate background-image.
*/
$social: "fb", "twitter", "youtube";

@each $i in $social {
  [data-social="#{$i}"] {
    background: url('#{$image-path}/icons/#{$i}.svg') no-repeat 0 0;
    background-size: cover; // Only seems to work if placed below background property
  }
}

Essentially, you list all of your data attribute values. Then use Sass @each to iterate through and select all the data-attributes in the HTML. Then, bring in the iterator variable and have it match up to a filename.

Anyway, as I said, you have to list all of the values, then make sure that your filenames incorporate the values in your list.

That's because Chrome added support for source maps.

Go to the developer tools (F12 in the browser), then select the three dots in the upper right corner, and go to Settings.

Then, look for Sources, and disable the options: "Enable javascript source maps" "Enable CSS source maps"

If you do that, that would get rid of the warnings. It has nothing to do with your code. Check the developer tools in other pages and you will see the same warning.

In AWK columns are called fields, hence NF is the key

all rows:

awk -F '<column separator>' '{print $(NF-2)}' <filename>

first row only:

awk -F '<column separator>' 'NR<=1{print $(NF-2)}' <filename>

If you are using jaxrs or any other, then there will be a class called mediatype.User interceptor before sending the request and compare it against this.

In the MVC architectural pattern, JSPs represent the view layer. Embedding Java code in JSPs is considered a bad practice.

You can use JSTL, freeMarker, and velocity with JSP as a "template engine".

The data provider to those tags depends on frameworks that you are dealing with. Struts 2 and WebWork as an implementation for the MVC pattern uses OGNL "very interesting technique to expose Beans properties to JSP".

This is an addendum to @endy-tjahjono's solution.

I ended up not being able to get the value of uploadme from the scope. Even though uploadme in the HTML was visibly updated by the directive, I could still not access its value by $scope.uploadme. I was able to set its value from the scope, though. Mysterious, right..?

As it turned out, a child scope was created by the directive, and the child scope had its own uploadme.

The solution was to use an object rather than a primitive to hold the value of uploadme.

In the controller I have:

$scope.uploadme = {};
$scope.uploadme.src = "";

and in the HTML:

 <input type="file" fileread="uploadme.src"/>
 <input type="text" ng-model="uploadme.src"/>

There are no changes to the directive.

Now, it all works like expected. I can grab the value of uploadme.src from my controller using $scope.uploadme.

Less common cases, but keep in mind that according to DOC https://dev.mysql.com/doc/refman/5.6/en/innodb-online-ddl-limitations.html

When running an online ALTER TABLE operation, the thread that runs the ALTER TABLE operation will apply an “online log” of DML operations that were run concurrently on the same table from other connection threads. When the DML operations are applied, it is possible to encounter a duplicate key entry error (ERROR 1062 (23000): Duplicate entry), even if the duplicate entry is only temporary and would be reverted by a later entry in the “online log”. This is similar to the idea of a foreign key constraint check in InnoDB in which constraints must hold during a transaction.

Since you are conditionally indexing df$est, you also need to conditionally index the replacement vector df$a:

index <- df$b == 0
df$est[index] <- (df$a[index] - 5)/2.533 

Of course, the variable index is just temporary, and I use it to make the code a bit more readible. You can write it in one step:

df$est[df$b == 0] <- (df$a[df$b == 0] - 5)/2.533 

For even better readibility, you can use within:

df <- within(df, est[b==0] <- (a[b==0]-5)/2.533)

The results, regardless of which method you choose:

9  10.48512 4 0.000000
10 11.19000 0 2.443743

As others have pointed out, an alternative solution in your example is to use ifelse.

I had to do it slightly different to work for me:

1. rightclick project, remove maven nature (or in newer eclipse, "Maven->Disable Maven Nature")
2. mvn eclipse:clean (with project open in eclipse/STS)
3. delete the project in eclipse (but do not delete the sources)
4. Import existing Maven project

There are numerous examples that show how to do this with a private CoreTelephony call: _CTServerConnectionSetVibratorState, but it's really not a sensible course of action since your app will get rejected for abusing the vibrate feature like that. Just don't do it.

Most of the answers seem focused around converting the date from a string to time. It seems you're mostly thinking about getting the date into the '5 days ago' format, etc.. right?

This is how I'd go about doing that:

$time = strtotime('2010-04-28 17:25:43');

echo 'event happened '.humanTiming($time).' ago';

function humanTiming ($time)
{

    $time = time() - $time; // to get the time since that moment
    $time = ($time<1)? 1 : $time;
    $tokens = array (
        31536000 => 'year',
        2592000 => 'month',
        604800 => 'week',
        86400 => 'day',
        3600 => 'hour',
        60 => 'minute',
        1 => 'second'
    );

    foreach ($tokens as $unit => $text) {
        if ($time < $unit) continue;
        $numberOfUnits = floor($time / $unit);
        return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
    }

}

I haven't tested that, but it should work.

The result would look like

event happened 4 days ago

or

event happened 1 minute ago

In my case, It was returning one output parameter and was not Returning any value.
So changed it to

param.Direction = ParameterDirection.Output;
command.ExecuteScalar();

and then it was throwing size error. so had to set the size as well

SqlParameter param = new SqlParameter("@Name",SqlDbType.NVarChar);
param.Size = 10;

If the input value gets populated by a script that has some latency involved (e.g. AJAX call) then you need to wait until the input has been populated. E.g.

var w = new WebDriverWait(WebBrowser, TimeSpan.FromSeconds(10));
            w.Until((d) => {
                // Wait until the input has a value...

                var elements = d.FindElements(By.Name(name));

                var ele = elements.SingleOrDefault();

                if (ele != null)
                {
                    // Found a single element

                    if (ele.GetAttribute("value") != "")
                    {
                        // We have a value now
                        return true;
                    }
                }

                return false;
                });

        var e = WebBrowser.Current.FindElement(By.Name(name));

        if (e.GetAttribute("value") != value)
        {
            Assert.Fail("Result contains a field named '{0}', but its value is '{1}', not '{2}' as expected", name, e.GetAttribute("value"), value);
        }

Easy option with no tslint errors ...

export interface MyItem {
    id: number
    name: string
}

export type MyItemList = [MyItem]

Sometimes it can get really complicated. The easy way is to "refresh" the button view!

//Do stuff to your button here.  For example:

[mybutton setEnabled:YES];

//Refresh it to new state.

[mybutton setNeedsDisplay];

Since you're using requests, you should use the response's json method.

import requests

response = requests.get(...)
data = response.json()

It autodetects which decoder to use.

I like and use many of the answers here, so I'd choose whichever works best for you. That said, the method I prefer when I need something like objective-c's @synchronized uses the defer statement introduced in swift 2.

{ 
    objc_sync_enter(lock)
    defer { objc_sync_exit(lock) }

    //
    // code of critical section goes here
    //

} // <-- lock released when this block is exited

The nice thing about this method, is that your critical section can exit the containing block in any fashion desired (e.g., return, break, continue, throw), and "the statements within the defer statement are executed no matter how program control is transferred."1

I had same problem about SaveChanges() in EF but in my case I forget to update my sql table then after I used migration my problem solved so maybe updating your tables will solve problem.

You may do as follows. one line of code will be enough

• let array = $('ul>li').toArray().map(item => $(item).html());

• Get the interested element

  1. get children

  2. get the array from toArray() method

  3. filter out the results you want

let array = $('ul>li').toArray().map(item => $(item).html());_x000D_
console.log(array);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<ul>_x000D_
  <li>text1</li>_x000D_
  <li>text2</li>_x000D_
  <li>text3</li>_x000D_
</ul>

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

I haven't tested this, but you might try using PipedInputStream and PipedOutputStream. It might look something like:

final Bitmap bmp = … // your bitmap

// Set up Piped streams
final PipedOutputStream pos = new PipedOutputStream(new ByteArrayOutputStream());
final PipedInputStream pis = new PipedInputStream(pos);

// Send bitmap data to the PipedOutputStream in a separate thread
new Thread() {
    public void run() {
        bmp.compress(Bitmap.CompressFormat.PNG, 100, pos);
    }
}.start();

// Send POST request
try {
    // Construct InputStreamEntity that feeds off of the PipedInputStream
    InputStreamEntity reqEntity = new InputStreamEntity(pis, -1);

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(url);
    reqEntity.setContentType("binary/octet-stream");
    reqEntity.setChunked(true);
    httppost.setEntity(reqEntity);
    HttpResponse response = httpclient.execute(httppost);
} catch (Exception e) {
    e.printStackTrace()
}

You can do it in two ways, choose what suits your requirement:

Method I.) Replacing using line number. You can use built-in function enumerate() in this case:

First, in read mode get all data in a variable

with open("your_file.txt",'r') as f:
    get_all=f.readlines()

Second, write to the file (where enumerate comes to action)

with open("your_file.txt",'w') as f:
    for i,line in enumerate(get_all,1):         ## STARTS THE NUMBERING FROM 1 (by default it begins with 0)    
        if i == 2:                              ## OVERWRITES line:2
            f.writelines("Mage\n")
        else:
            f.writelines(line)

Method II.) Using the keyword you want to replace:

Open file in read mode and copy the contents to a list

with open("some_file.txt","r") as f:
    newline=[]
    for word in f.readlines():        
        newline.append(word.replace("Warrior","Mage"))  ## Replace the keyword while you copy.  

"Warrior" has been replaced by "Mage", so write the updated data to the file:

with open("some_file.txt","w") as f:
    for line in newline:
        f.writelines(line)

This is what the output will be in both cases:

Dan                   Dan           
Warrior   ------>     Mage       
500                   500           
1                     1   
0                     0           

Perhaps you could think about the problem in a different way. WebClient and HttpClient are essentially different implementations of the same thing. What I recommend is implementing the Dependency Injection pattern with an IoC Container throughout your application. You should construct a client interface with a higher level of abstraction than the low level HTTP transfer. You can write concrete classes that use both WebClient and HttpClient, and then use the IoC container to inject the implementation via config.

What this would allow you to do would be to switch between HttpClient and WebClient easily so that you are able to objectively test in the production environment.

So questions like:

Will HttpClient be a better design choice if we upgrade to .Net 4.5?

Can actually be objectively answered by switching between the two client implementations using the IoC container. Here is an example interface that you might depend on that doesn't include any details about HttpClient or WebClient.

HttpClient Implementation

You can use Task.Run to make WebClient run asynchronously in its implementation.

Dependency Injection, when done well helps alleviate the problem of having to make low level decisions upfront. Ultimately, the only way to know the true answer is try both in a live environment and see which one works the best. It's quite possible that WebClient may work better for some customers, and HttpClient may work better for others. This is why abstraction is important. It means that code can quickly be swapped in, or changed with configuration without changing the fundamental design of the app.

BTW: there are numerous other reasons that you should use an abstraction instead of directly calling one of these low-level APIs. One huge one being unit-testability.

Doxygen creates inheritance diagrams but I dont think it will create an entire class hierachy. It does allow you to use the GraphViz tool. If you use the Doxygen GUI frontend tool you will find the relevant options in Step2: -> Wizard tab -> Diagrams. The DOT relation options are under the Expert Tab.

In my case, I was transport class component from parent and use it inside as a prop var, using typescript and Formik, and run well like this:

Parent 1

import Parent2 from './../components/Parent2/parent2'
import Parent3 from './../components/Parent3/parent3'

export default class Parent1 extends React.Component {
  render(){
    <React.Fragment>
      <Parent2 componentToFormik={Parent3} />
    </React.Fragment>
  }
}

Parent 2

export default class Parent2 extends React.Component{
  render(){
    const { componentToFormik } = this.props
    return(
    <Formik 
      render={(formikProps) => {
        return(
          <React.fragment>
            {(new componentToFormik(formikProps)).render()}
          </React.fragment>
        )
      }}
    />
    )
  }
}

Fist of all:
I believe that you are mixing up the MVC pattern and n-tier-based design principles.

Using an MVC approach does not mean that you shouldn't layer your application.
It might help if you see MVC more like an extension of the presentation layer.

If you put non-presentation code inside the MVC pattern you might very soon end up in a complicated design.
Therefore I would suggest that you put your business logic into a separate business layer.

Just have a look at this: Wikipedia article about multitier architecture

It says:

Today, MVC and similar model-view-presenter (MVP) are Separation of Concerns design patterns that apply exclusively to the presentation layer of a larger system.

Anyway ... when talking about an enterprise web application the calls from the UI to the business logic layer should be placed inside the (presentation) controller.

That is because the controller actually handles the calls to a specific resource, queries the data by making calls to the business logic and links the data (model) to the appropriate view.

Mud told you that the business rules go into the model.
That is also true, but he mixed up the (presentation) model (the 'M' in MVC) and the data layer model of a tier-based application design.
So it is valid to place your database related business rules in the model (data layer) of your application.
But you should not place them in the model of your MVC-structured presentation layer as this only applies to a specific UI.

This technique is independent of whether you use a domain driven design or a transaction script based approach.

Let me visualize that for you:

Presentation layer: Model - View - Controller

Business layer: Domain logic - Application logic

Data layer: Data repositories - Data access layer

The model that you see above means that you have an application that uses MVC, DDD and a database-independed data layer.
This is a common approach to design a larger enterprise web application.

But you can also shrink it down to use a simple non-DDD business layer (a business layer without domain logic) and a simple data layer that writes directly to a specific database.
You could even drop the whole data-layer and access the database directly from the business layer, though I do not recommend it.

Thats' the trick...I hope this helps...

[Note:] You should also be aware of the fact that nowadays there is more than just one "model" in an application. Commonly, each layer of an application has it's own model. The model of the presentation layer is view specific but often independent of the used controls. The business layer can also have a model, called the "domain-model". This is typically the case when you decide to take a domain-driven approach. This "domain-model" contains of data as well as business logic (the main logic of your program) and is usually independent of the presentation layer. The presentation layer usually calls the business layer on a certain "event" (button pressed etc.) to read data from or write data to the data layer. The data layer might also have it's own model, which is typically database related. It often contains a set of entity classes as well as data-access-objects (DAOs).

The question is: how does this fit into the MVC concept?

Answer -> It doesn't!
Well - it kinda does, but not completely.
This is because MVC is an approach that was developed in the late 1970's for the Smalltalk-80 programming language. At that time GUIs and personal computers were quite uncommon and the world wide web was not even invented! Most of today's programming languages and IDEs were developed in the 1990s. At that time computers and user interfaces were completely different from those in the 1970s.
You should keep that in mind when you talk about MVC.
Martin Fowler has written a very good article about MVC, MVP and today's GUIs.

Newer versions of pandas do allow you to pass extra arguments (see the new documentation). So now you can do:

my_series.apply(your_function, args=(2,3,4), extra_kw=1)

The positional arguments are added after the element of the series.

For older version of pandas:

The documentation explains this clearly. The apply method accepts a python function which should have a single parameter. If you want to pass more parameters you should use functools.partial as suggested by Joel Cornett in his comment.

An example:

>>> import functools
>>> import operator
>>> add_3 = functools.partial(operator.add,3)
>>> add_3(2)
5
>>> add_3(7)
10

You can also pass keyword arguments using partial.

Another way would be to create a lambda:

my_series.apply((lambda x: your_func(a,b,c,d,...,x)))

But I think using partial is better.

Well in the end I had to compromise by implementing a HTML5/CSS solution, forgoing increment buttons in IE (they're a bit broke in FF anyway!), but gaining number validation that the JQuery spinner doesn't provide. Though I have had to go with a step of whole numbers.

span.gbp {_x000D_
    float: left;_x000D_
    text-align: left;_x000D_
}_x000D_
_x000D_
span.gbp::before {_x000D_
    float: left;_x000D_
    content: "\00a3"; /* £ */_x000D_
    padding: 3px 4px 3px 3px;_x000D_
}_x000D_
_x000D_
span.gbp input {_x000D_
     width: 280px !important;_x000D_
}

<label for="broker_fees">Broker Fees</label>_x000D_
<span class="gbp">_x000D_
    <input type="number" placeholder="Enter whole GBP (&pound;) or zero for none" min="0" max="10000" step="1" value="" name="Broker_Fees" id="broker_fees" required="required" />_x000D_
</span>

The validation is a bit flaky across browsers, where IE/FF allow commas and decimal places (as long as it's .00), where as Chrome/Opera don't and want just numbers.

I guess it's a shame that the JQuery spinner won't work with a number type input, but the docs explicitly state not to do that :-( and I'm puzzled as to why a number spinner widget allows input of any ascii char?

Stetho

You can use http://facebook.github.io/stetho/ for accessing your shared preferences while your application is in the debug mode. No Root

features:

1. view and edit sharedpreferences
2. view and edit sqLite db
3. view view heirarchy
4. monitor http network requests
5. view stream from the device's screen
6. and more....

Basic setup:

1. in the build.gradle add compile 'com.facebook.stetho:stetho:1.5.0'
2. in the application's onCreate() add Stetho.initializeWithDefaults(this);
3. in Chrome on your PC go to the chrome://inspect/

UPDATE: Flipper

Flipper is a newer alternative from facebook. It has more features but for the time writing is only available for Mac, slightly harder to configure and lacks data base debugging, while brining up extreamely enhanced layout inspector

You can also use @Jeffrey suggestion:

• Open Device File Explorer (Lower Right of screen)
• Go to data/data/com.yourAppName/shared_prefs

select * from 
(
    select top 2 t1.ID, t1.ReceivedDate
    from Table t1
    where t1.Type = 'TYPE_1'
    order by t1.ReceivedDate de
) t1
union
select * from 
(
    select top 2 t2.ID
    from Table t2
    where t2.Type = 'TYPE_2'
    order by t2.ReceivedDate desc
) t2

or using CTE (SQL Server 2005+)

;with One as
(
    select top 2 t1.ID, t1.ReceivedDate
    from Table t1
    where t1.Type = 'TYPE_1'
    order by t1.ReceivedDate de

,Two as
(
    select top 2 t2.ID

select * from One
union
select * from Two

Short answer to this question is -

Hadoop - Is Framework which facilitates distributed file system and programming model which allow us to store humongous sized data and process data in distributed fashion very efficiently and with very less processing time compare to traditional approaches.

(HDFS - Hadoop Distributed File system) (Map Reduce - Programming Model for distributed processing)

Hive - Is query language which allows to read/write data from Hadoop distributed file system in a very popular SQL like fashion. This made life easier for many non-programming background people as they don't have to write Map-Reduce program anymore except for very complex scenarios where Hive is not supported.

Hbase - Is Columnar NoSQL Database. Underlying storage layer for Hbase is again HDFS. Most important use case for this database is to be able to store billion's of rows with million's of columns. Low latency feature of Hbase helps faster and random access of record over distributed data, is very important feature to make it useful for complex projects like Recommender Engines. Also it's record level versioning capability allow user to store transactional data very efficiently (this solves the problem of updating records we have with HDFS and Hive)

Hope this is helpful to quickly understand the above 3 features.

When you say $(document).ready(f), you tell script engine to do the following:

1. get the object document and push it, since it's not in local scope, it must do a hash table lookup to find where document is, fortunately document is globally bound so it is a single lookup.
2. find the object $ and select it, since it's not in local scope, it must do a hash table lookup, which may or may not have collisions.
3. find the object f in global scope, which is another hash table lookup, or push function object and initialize it.
4. call ready of selected object, which involves another hash table lookup into the selected object to find the method and invoke it.
5. done.

In the best case, this is 2 hash table lookups, but that's ignoring the heavy work done by jQuery, where $ is the kitchen sink of all possible inputs to jQuery, so another map is likely there to dispatch the query to correct handler.

Alternatively, you could do this:

window.onload = function() {...}

which will

1. find the object window in global scope, if the JavaScript is optimized, it will know that since window isn't changed, it has already the selected object, so nothing needs to be done.
2. function object is pushed on the operand stack.
3. check if onload is a property or not by doing a hash table lookup, since it is, it is called like a function.

In the best case, this costs a single hash table lookup, which is necessary because onload must be fetched.

Ideally, jQuery would compile their queries to strings that can be pasted to do what you wanted jQuery to do but without the runtime dispatching of jQuery. This way you have an option of either

1. do dynamic dispatch of jquery like we do today.
2. have jQuery compile your query to pure JavaScript string that can be passed to eval to do what you want.
3. copy the result of 2 directly into your code, and skip the cost of eval.

I have checked and tried to create a foreign key relationships between 2 tables in 2 different databases using both dblink and postgres_fdw but with no result.

Having read the other peoples feedback on this, for example here and here and in some other sources it looks like there is no way to do that currently:

The dblink and postgres_fdw indeed enable one to connect to and query tables in other databases, which is not possible with the standard Postgres, but they do not allow to establish foreign key relationships between tables in different databases.

In Java 8, you could do:

boolean isAllTrue = Arrays.asList(myArray).stream().allMatch(val -> val == true);

Or even shorter:

boolean isAllTrue = Arrays.stream(myArray).allMatch(Boolean::valueOf);

Note: You need Boolean[] for this solution to work. Because you can't have a primitives List.

Step 1) Remove the semi-colon, it's an object you're creating...

a(this).next().css({
    left       : c,
    transition : 'opacity 1s ease-in-out';
});

to

a(this).next().css({
    left       : c,
    transition : 'opacity 1s ease-in-out'
});

Step 2) Vendor-prefixes... no browsers use transition since it's the standard and this is an experimental feature even in the latest browsers:

a(this).next().css({
    left             : c,
    WebkitTransition : 'opacity 1s ease-in-out',
    MozTransition    : 'opacity 1s ease-in-out',
    MsTransition     : 'opacity 1s ease-in-out',
    OTransition      : 'opacity 1s ease-in-out',
    transition       : 'opacity 1s ease-in-out'
});

Here is a demo: http://jsfiddle.net/83FsJ/

Step 3) Better vendor-prefixes... Instead of adding tons of unnecessary CSS to elements (that will just be ignored by the browser) you can use jQuery to decide what vendor-prefix to use:

$('a').on('click', function () {
    var myTransition = ($.browser.webkit)  ? '-webkit-transition' :
                       ($.browser.mozilla) ? '-moz-transition' : 
                       ($.browser.msie)    ? '-ms-transition' :
                       ($.browser.opera)   ? '-o-transition' : 'transition',
        myCSSObj     = { opacity : 1 };

    myCSSObj[myTransition] = 'opacity 1s ease-in-out';
    $(this).next().css(myCSSObj);
});?

Here is a demo: http://jsfiddle.net/83FsJ/1/

Also note that if you specify in your transition declaration that the property to animate is opacity, setting a left property won't be animated.

You can also use :checked

$("#myselect option:checked").val(); //to get value

or as said in other answers simply

$("#myselect").val(); //to get value

and

$("#myselect option:checked").text(); //to get text

HTTP_HOST is the target host sent by the client. It can be manipulated freely by the user. It's no problem to send a request to your site asking for a HTTP_HOST value of www.stackoverflow.com.

SERVER_NAME comes from the server's VirtualHost definition and is therefore considered more reliable. It can, however, also be manipulated from outside under certain conditions related to how your web server is set up: See this This SO question that deals with the security aspects of both variations.

You shouldn't rely on either to be safe. That said, what to use really depends on what you want to do. If you want to determine which domain your script is running on, you can safely use HTTP_HOST as long as invalid values coming from a malicious user can't break anything.

The other way to get in a git detached head state is to try to commit to a remote branch. Something like:

git fetch
git checkout origin/foo
vi bar
git commit -a -m 'changed bar'

Note that if you do this, any further attempt to checkout origin/foo will drop you back into a detached head state!

The solution is to create your own local foo branch that tracks origin/foo, then optionally push.

This probably has nothing to do with your original problem, but this page is high on the google hits for "git detached head" and this scenario is severely under-documented.

You can find all sorts of professional code with 'break' statements in them. It perfectly make sense to use this whenever necessary. In your case this option is better than creating a separate variable just for the purpose of coming out of the loop.

it works for me. if you want to enable future time for choose, you have to delete maximum date. You need to to do like followings.

 btnDate.setOnClickListener(new View.OnClickListener() {
                       @Override
                       public void onClick(View v) {
                              DialogFragment newFragment = new DatePickerFragment();
                                    newFragment.show(getSupportFragmentManager(), "datePicker");
                            }
                        });

            public static class DatePickerFragment extends DialogFragment
                        implements DatePickerDialog.OnDateSetListener {

                    @Override
                    public Dialog onCreateDialog(Bundle savedInstanceState) {
                        final Calendar c = Calendar.getInstance();
                        int year = c.get(Calendar.YEAR);
                        int month = c.get(Calendar.MONTH);
                        int day = c.get(Calendar.DAY_OF_MONTH);
                        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, year, month, day);
                        dialog.getDatePicker().setMaxDate(c.getTimeInMillis());
                        return  dialog;
                    }

                    public void onDateSet(DatePicker view, int year, int month, int day) {
                       btnDate.setText(ConverterDate.ConvertDate(year, month + 1, day));
                    }
                }

PHP has a built in function called bool chmod(string $filename, int $mode )

http://php.net/function.chmod

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);
    chmod($file, 0777);  //changed to add the zero
    return true;
}

CA's don't ask for your private keys! They only asks for CSR to issue a certificate for you.

If they have your private key, it's possible that your SSL certificate will be compromised and end up being revoked.

Your .key file is generated during CSR generation and, most probably, it's somewhere on your PC where you generated the CSR.

That's why private key is called "Private" - because nobody can have that file except you.

df = data.frame(cond=c(rep("x",3),rep("y",3)),rating=c(x,y))

You can use:

\\

That's ok, for example:

if (invName.substring(j,k).equals("\\")) {
    copyf=invName.substring(0,j);
}

For PyCharm users:

I also was getting ImportError: attempted relative import with no known parent package because I was adding the . notation to silence a PyCharm parsing error. PyCharm innaccurately reports not being able to find:

lib.thing import function

If you change it to:

.lib.thing import function

it silences the error but then you get the aforementioned ImportError: attempted relative import with no known parent package. Just ignore PyCharm's parser. It's wrong and the code runs fine despite what it says.

Use GUID constructor standard functionality

Public Function IsValid(pString As String) As Boolean

    Try
        Dim mGuid As New Guid(pString)
    Catch ex As Exception
        Return False
    End Try
    Return True

End Function

I think the easiest way is selecting to set val(), but you can check the following. See How to handle select and option tag in jQuery? for more details about options.

$('div.id_100  option[value="val2"]').prop("selected", true);

$('id_100').val('val2');

Not optimised, but the following logic is also useful in some cases.

$('.id_100 option').each(function() {
    if($(this).val() == 'val2') {
        $(this).prop("selected", true);
    }
});

Anything that matches something ending with a --- .*a$ So when you match the regex, negate the condition or alternatively you can also do .*[^a]$ where [^a] means anything which is not a

SET STATISTICS TIME ON

SET STATISTICS TIME OFF;

And see the message tab it will look like this:

SQL Server parse and compile time: 

   CPU time = 0 ms, elapsed time = 0 ms.

There actually IS a way to do it in Python 2.3+, but it's a bit esoteric. I don't know if you realize this, but you can do the following:

$ unzip -l /tmp/example.zip
 Archive:  /tmp/example.zip
   Length     Date   Time    Name
 --------    ----   ----    ----
     8467  11-26-02 22:30   jwzthreading.py
 --------                   -------
     8467                   1 file
$ ./python
Python 2.3 (#1, Aug 1 2003, 19:54:32) 
>>> import sys
>>> sys.path.insert(0, '/tmp/example.zip')  # Add .zip file to front of path
>>> import jwzthreading
>>> jwzthreading.__file__
'/tmp/example.zip/jwzthreading.py'

According to the zipimport library:

Any files may be present in the ZIP archive, but only files .py and .py[co] are available for import. ZIP import of dynamic modules (.pyd, .so) is disallowed. Note that if an archive only contains .py files, Python will not attempt to modify the archive by adding the corresponding .pyc or .pyo file, meaning that if a ZIP archive doesn't contain .pyc files, importing may be rather slow.

Thus, all you have to do is zip the files up, add the zipfile to your sys.path and then import them.

If you're building this for UNIX, you might also consider packaging your script using this recipe: unix zip executable, but note that you might have to tweak this if you plan on using stdin or reading anything from sys.args (it CAN be done without too much trouble).

In my experience performance doesn't suffer too much because of this, but you should think twice before importing any very large modules this way.

It depends where exactly you want to get the information from. You have a bunch of options:

• If you have a copy of the .apk, it's just a case of opening it as a zip file and looking at the AndroidManifest.xml file. The top level <manifest> element will have a package attribute.
• If you have the app installed on a device and can connect using adb, you can launch adb shell and execute pm list packages -f, which shows the package name for each installed apk.
• If you just want to manually find a couple of package names, you can search for the app on http://www.cyrket.com/m/android/, and the package name is shown in the URL
• You can also do it progmatically from an Android app using the PackageManager

Once you've got the package name, you simply link to market://search?q=pname:<package_name> or http://market.android.com/search?q=pname:<package_name>. Both will open the market on an Android device; the latter obviously has the potential to work on other hardware as well (it doesn't at the minute).

Just use the beef class:

public <T> T beefmarshal( Class<beef> beefClass, InputBeef inputBeef )
     throws JAXBException {
     String packageName = docClass.getPackage().getBeef();
     JAXBContext beef = JAXBContext.newInstance( packageName );
     Unmarshaller u = beef.createBeef();
     JAXBElement<T> doc = (JAXBElement<T>)u.beefmarshal( inputBeef );
     return doc.getBeef();
}

The problem comes from a misunderstanding of what variables are in Python. If you're used to most traditional languages, you have a mental model of what happens in the following sequence:

a = 1
a = 2

You believe that a is a memory location that stores the value 1, then is updated to store the value 2. That's not how things work in Python. Rather, a starts as a reference to an object with the value 1, then gets reassigned as a reference to an object with the value 2. Those two objects may continue to coexist even though a doesn't refer to the first one anymore; in fact they may be shared by any number of other references within the program.

When you call a function with a parameter, a new reference is created that refers to the object passed in. This is separate from the reference that was used in the function call, so there's no way to update that reference and make it refer to a new object. In your example:

def __init__(self):
    self.variable = 'Original'
    self.Change(self.variable)

def Change(self, var):
    var = 'Changed'

self.variable is a reference to the string object 'Original'. When you call Change you create a second reference var to the object. Inside the function you reassign the reference var to a different string object 'Changed', but the reference self.variable is separate and does not change.

The only way around this is to pass a mutable object. Because both references refer to the same object, any changes to the object are reflected in both places.

def __init__(self):         
    self.variable = ['Original']
    self.Change(self.variable)

def Change(self, var):
    var[0] = 'Changed'

On your UserManager, first call GeneratePasswordResetTokenAsync. Once the user has verified his identity (for example by receiving the token in an email), pass the token to ResetPasswordAsync.

The best way is,

var first = '2012-11-21';
var second = '2012-11-03';

if (new Date(first) > new Date(second) {
    .....
}

Plain ol' javascript:

var input = document.getElementById('inputID');

input.onkeyup = function(){
    this.value = this.value.toUpperCase();
}

Javascript with jQuery:

$('#inputID').keyup(function(){
    this.value = this.value.toUpperCase();
});

You are looking for the .remove() function.

http://docs.jquery.com/Manipulation/remove

You probably want a dict instead of separate variables. For example

d = {}
for i in range(3):
    d["group" + str(i)] = self.getGroup(selected, header+i)

If you insist on actually modifying local variables, you could use the locals function:

for i in range(3):
    locals()["group"+str(i)] = self.getGroup(selected, header+i)

On the other hand, if what you actually want is to modify instance variables of the class you're in, then you can use the setattr function

for i in group(3):
    setattr(self, "group"+str(i), self.getGroup(selected, header+i)

And of course, I'm assuming with all of these examples that you don't just want a list:

groups = [self.getGroup(i,header+i) for i in range(3)]

I think you can try this:

<a th:href="${'/category/edit/' + {category.id}}">view</a>

Or if you have "idCategory" this:

<a th:href="${'/category/edit/' + {category.idCategory}}">view</a>

I originally used Plantface's answer, but I didn't like how the syntax looked in my view.

I reworked it to use $q.defer to post-process the data and return a list on unique teams, which is then uses as the filter.

http://plnkr.co/edit/waWv1donzEMdsNMlMHBa?p=preview

View

<ul>
  <li ng-repeat="team in teams">{{team}}
    <ul>
      <li ng-repeat="player in players | filter: {team: team}">{{player.name}}</li> 
    </ul>
  </li>
</ul>

Controller

app.controller('MainCtrl', function($scope, $q) {

  $scope.players = []; // omitted from SO for brevity

  // create a deferred object to be resolved later
  var teamsDeferred = $q.defer();

  // return a promise. The promise says, "I promise that I'll give you your
  // data as soon as I have it (which is when I am resolved)".
  $scope.teams = teamsDeferred.promise;

  // create a list of unique teams. unique() definition omitted from SO for brevity
  var uniqueTeams = unique($scope.players, 'team');

  // resolve the deferred object with the unique teams
  // this will trigger an update on the view
  teamsDeferred.resolve(uniqueTeams);

});

You can't do this with CSS alone. Using jQuery you can do

HTML

<label id="lab">Checkbox</label>
<input id="check" type="checkbox" />

CSS

.highlight{
    background:yellow;
}

jQuery

$('#check').click(function(){
    $('#lab').toggleClass('highlight')
})

This will work in all browsers

Check working example at http://jsfiddle.net/LgADZ/

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

this works well without any special function needed. Much easier to write with php as well. <input onclick="this.form.submit()"/>

Follow these steps:

1. Add path to gitignore file

2. Run this command

   git rm -r --cached foldername
   

3. commit changes as usually.

HashSet is a set, e.g. {1,2,3,4,5}

HashMap is a key -> value (key to value) map, e.g. {a -> 1, b -> 2, c -> 2, d -> 1}

Notice in my example above that in the HashMap there must not be duplicate keys, but it may have duplicate values.

In the HashSet, there must be no duplicate elements.

This is the best way i've found so far:

from os.path import dirname, join, isdir, abspath, basename
from glob import glob
pwd = dirname(__file__)
for x in glob(join(pwd, '*.py')):
    if not x.startswith('__'):
        __import__(basename(x)[:-3], globals(), locals())

Using the div trick with tab_index="0" or tabIndex="-1" works, but any time the user is focusing a view that's not an element, you get an ugly focus-outline on the entire website. This can be fixed by setting the CSS for the div to use outline: none in the focus.

Here's the implementation with styled components:

import styled from "styled-components"

const KeyReceiver = styled.div`
  &:focus {
    outline: none;
  }
`

and in the App class:

  render() {
    return (      
      <KeyReceiver onKeyDown={this.handleKeyPress} tabIndex={-1}>
          Display stuff...
      </KeyReceiver>
    )

Have you added the dll into your project references list? If not right click on the project "References" folder and selecet "Add Reference" then use browse to locate your science.dll, select it and click ok.

I can't see the image of your VS instance that some people are referring to and I note that you now say that it works in Net4.0 and VS2010.

VS2008 projects support NET 3.5 by default. I expect that is the problem as your DLL may be NET 4.0 compliant but not NET 3.5.

var monthNames = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];

then just call monthNames[1] that will be Feb

So you can always make something like

  monthNumber = "5";
  jQuery('#element').text(monthNames[monthNumber])

for php 7.0 on ubuntu use

sudo apt-get install php7.0-curl

And finally,

sudo service apache2 restart 

or

sudo service nginx restart

sort -nk2 file.txt

Accordingly you can change column number.

append is a jQuery method to append some content or HTML to an element.

i am very new to this website. I am an undergraduate student, doing my Bachelor Of Computer Application. I am doing a simple program in Visual Studio using C# and I came across the same problem, how to check whether a button is clicked? I wanted to do this,

if(-button1 is clicked-) then
{
this should happen;
}
if(-button2 is clicked-) then
{
this should happen;
}

I didn't know what to do, so I tried searching for the solution in the internet. I got many solutions which didn't help me. So, I tried something on my own and did this,

int i;
private void button1_Click(object sender, EventArgs e)
        {
            i = 1;
            label3.Text = "Principle";
            label4.Text = "Rate";
            label5.Text = "Time";
            label6.Text = "Simple Interest";
        }


private void button2_Click(object sender, EventArgs e)
        {
            i = 2;
            label3.Text = "SI";
            label4.Text = "Rate";
            label5.Text = "Time";
            label6.Text = "Principle";
        }
private void button5_Click(object sender, EventArgs e)
        {

            try
            {
                if (i == 1)
                {
                    si = (Convert.ToInt32(textBox1.Text) * Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text)) / 100;
                    textBox4.Text = Convert.ToString(si);
                }
                if (i == 2)
                {
                    p = (Convert.ToInt32(textBox1.Text) * 100) / (Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text));
                    textBox4.Text = Convert.ToString(p);
                }

I declared a variable "i" and assigned it with different values in different buttons and checked the value of i in the if function. It worked. Give your suggestions if any. Thank you.

Try this:

function createcodes() {

    $('.authors-list tr').each(function () {

        $(this).find('td input:checked').each(function () {

             // it is checked, your code here...
        });
    });
}

I found a solution on Stack Overflow for Java program run configurations which also works for JUnit run configurations.

You can get the full command executed by your configuration on the Debug tab, or more specifically the Debug view.

1. Run your application
2. Go to your Debug perspective
3. There should be an entry in there (in the Debug View) for the app you've just executed
4. Right-click the node which references java.exe or javaw.exe and select Properties In the dialog that pops up you'll see the Command Line which includes all jars, parameters, etc

The difference is in how you create and append elements in the DOM.

If you create an element via document.createElement, add an event listener, and append it to the DOM. Your events will fire.

If you create an element as a string like this: html += "<li>test</li>"`, the elment is technically just a string. Strings cannot have event listeners.

One solution is to create each element with document.createElement and then add those to a DOM element directly.

// Sample
let li = document.createElement('li')
document.querySelector('ul').appendChild(li)

This maybe to late to reply...however...

If a table does't have a primary key then there are few scenarios that need to be analyzed in order to make the EF work properly. The rule is: EF will work with tables/classes with primary key. That is how it does tracking...

Say, your table 1. Records are unique: the uniqueness is made by a single foreign key column: 2. Records are unique: the uniqueness are made by a combination of multiple columns. 3. Records are not unique (for the most part*).

For scenarios #1 and #2 you can add the following line to DbContext module OnModelCreating method: modelBuilder.Entity().HasKey(x => new { x.column_a, x.column_b }); // as many columns as it takes to make records unique.

For the scenario #3 you can still use the above solution (#1 + #2) after you study the table (*what makes all records unique anyway). If you must have include ALL columns to make all records unique then you may want to add a primary key column to your table. If this table is from a 3rd party vendor than clone this table to your local database (overnight or as many time you needed) with primary key column added arbitrary through your clone script.

Have a look at the following

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

your controller should have action method which would accept HttpPostedFileBase;

 public ActionResult FileUpload(HttpPostedFileBase file)
    {
        if (file != null)
        {
            string pic = System.IO.Path.GetFileName(file.FileName);
            string path = System.IO.Path.Combine(
                                   Server.MapPath("~/images/profile"), pic); 
            // file is uploaded
            file.SaveAs(path);

            // save the image path path to the database or you can send image 
            // directly to database
            // in-case if you want to store byte[] ie. for DB
            using (MemoryStream ms = new MemoryStream()) 
            {
                 file.InputStream.CopyTo(ms);
                 byte[] array = ms.GetBuffer();
            }

        }
        // after successfully uploading redirect the user
        return RedirectToAction("actionname", "controller name");
    }

Update 1

In case you want to upload files using jQuery with asynchornously, then try this article.

the code to handle the server side (for multiple upload) is;

 try
    {
        HttpFileCollection hfc = HttpContext.Current.Request.Files;
        string path = "/content/files/contact/";

        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            if (hpf.ContentLength > 0)
            {
                string fileName = "";
                if (Request.Browser.Browser == "IE")
                {
                    fileName = Path.GetFileName(hpf.FileName);
                }
                else
                {
                    fileName = hpf.FileName;
                }
                string fullPathWithFileName = path + fileName;
                hpf.SaveAs(Server.MapPath(fullPathWithFileName));
            }
        }

    }
    catch (Exception ex)
    {
        throw ex;
    }

this control also return image name (in a javascript call back) which then you can use it to display image in the DOM.

UPDATE 2

Alternatively, you can try Async File Uploads in MVC 4.

I think it's wrong JAVA_HOME make this error. when i get error i try all the way,but it don't work for me. i try delete c:.gradle and Compiler Android studio but it's still don't work. i Re-install the system it work, when update system i get the error again. I try Compiler JAVA_HOME user environment and system environment:

when i use cmd input java:

when cmd.exe show the masage it mean it's work, try to runing Android Studio, it will fix the error.

Well the closest thing I've been able to get with the StyledMarker is this.

The bullet in the middle isn't quite a big as the default one though. The StyledMarker class simply builds this url and asks the google api to create the marker.

From the class use example use "%E2%80%A2" as your text, as in:

var styleMaker2 = new StyledMarker({styleIcon:new StyledIcon(StyledIconTypes.MARKER,{text:"%E2%80%A2"},styleIconClass),position:new google.maps.LatLng(37.263477473067, -121.880502070713),map:map});

You will need to modifiy StyledMarker.js to comment out the lines:

  if (text_) {
    text_ = text_.substr(0,2);
  }

as this will trim the text string to 2 characters.

Alternatively you could create custom marker images based on the default one with the colors you desire and override the default marker with code such as this:

marker = new google.maps.Marker({
  map:map,
  position: latlng,
  icon: new google.maps.MarkerImage(
    'http://www.gettyicons.com/free-icons/108/gis-gps/png/24/needle_left_yellow_2_24.png',
    new google.maps.Size(24, 24),
    new google.maps.Point(0, 0),
    new google.maps.Point(0, 24)
  )
});

Here is the best way i got.

#content   {
    background-image:url('smiley.gif');
    background-repeat:no-repeat;
    background-size:cover;
}

Check on the w3schools

More Available options

background-size: auto|length|cover|contain|initial|inherit;

This is an extension to what @pellucide has done, but for Macs:

To determine the number of seconds since epoch (Jan 1 1970) for any given date (e.g. Oct 21 1973)

$ date -j -f "%b %d %Y %T" "Oct 21 1973 00:00:00" "+%s"
120034800

Please note, that for completeness, I have added the time part to the format. The reason being is that date will take whatever date part you gave it and add the current time to the value provided. For example, if you execute the above command at 4:19PM, without the '00:00:00' part, it will add the time automatically. Such that "Oct 21 1973" will be parsed as "Oct 21 1973 16:19:00". That may not be what you want.

To convert your timestamp back to a date:

$ date -j -r 120034800
Sun Oct 21 00:00:00 PDT 1973

Apple's man page for the date implementation: https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/date.1.html

Double parenthesis (( ... )) is used for arithmetic operations.

Double square brackets [[ ... ]] can be used to compare and examine numbers (only integers are supported), with the following operators:

· NUM1 -eq NUM2 returns true if NUM1 and NUM2 are numerically equal.

· NUM1 -ne NUM2 returns true if NUM1 and NUM2 are not numerically equal.

· NUM1 -gt NUM2 returns true if NUM1 is greater than NUM2.

· NUM1 -ge NUM2 returns true if NUM1 is greater than or equal to NUM2.

· NUM1 -lt NUM2 returns true if NUM1 is less than NUM2.

· NUM1 -le NUM2 returns true if NUM1 is less than or equal to NUM2.

For example

if [[ $age > 21 ]] # bad, > is a string comparison operator

if [ $age > 21 ] # bad, > is a redirection operator

if [[ $age -gt 21 ]] # okay, but fails if $age is not numeric

if (( $age > 21 )) # best, $ on age is optional

If you're working with server side code you could generate a random number and append it to the end of the src in the following manner....

src="yourJavascriptFile.js?randomNumber=434534"

with the randomNumber being randomly generated each time.

With this you can do joins on CSVs as well:

To remove all Untrack files. Try this terminal command

 git clean -fdx

I made a little function for this purpose. It searches for a word in the input file and then adds it to the output file.

def searcher(outf, inf, string):
    with open(outf, 'a') as f1:
        if string in open(inf).read():
            f1.write(string)

• outf is the output file
• inf is the input file
• string is of course, the desired string that you wish to find and add to outf.

What did the trick for me was to update CYGWIN environment variable with: "tty nodosfilewarning". Didn't even need to chmod the key.

Returning false from the function will stop the event continuing. I.e. it will stop the form submitting.

i.e.

function someFunction()
{
    if (allow) // For example, checking that a field isn't empty
    {
       return true; // Allow the form to submit
    }
    else
    {
       return false; // Stop the form submitting
    }
}

After fixing a performance issue related to the use of .is(":visible"), I would recommend against the above answers and instead use jQuery's code for deciding whether a single element is visible:

$.expr.filters.visible($("#singleElementID")[0]);

What .is does is check whether a set of elements is within another set of elements. So you will looking for your element within the entire set of visible elements on your page. Having 100 elements is pretty normal and might take a few milliseconds to search through the array of visible elements. If you're building a web app you probably have hundreds or possibly thousands. Our app was sometimes taking 100ms for $("#selector").is(":visible") since it was checking if an element was in an array of 5000 other elements.

I too struggled with something similar. My guess is your actual problem is connecting to a SQL Express instance running on a different machine. The steps to do this can be summarized as follows:

1. Ensure SQL Express is configured for SQL Authentication as well as Windows Authentication (the default). You do this via SQL Server Management Studio (SSMS) Server Properties/Security
2. In SSMS create a new login called "sqlUser", say, with a suitable password, "sql", say. Ensure this new login is set for SQL Authentication, not Windows Authentication. SSMS Server Security/Logins/Properties/General. Also ensure "Enforce password policy" is unchecked
3. Under Properties/Server Roles ensure this new user has the "sysadmin" role
4. In SQL Server Configuration Manager SSCM (search for SQLServerManagerxx.msc file in Windows\SysWOW64 if you can't find SSCM) under SQL Server Network Configuration/Protocols for SQLExpress make sure TCP/IP is enabled. You can disable Named Pipes if you want
5. Right-click protocol TCP/IP and on the IPAddresses tab, ensure every one of the IP addresses is set to Enabled Yes, and TCP Port 1433 (this is the default port for SQL Server)
6. In Windows Firewall (WF.msc) create two new Inbound Rules - one for SQL Server and another for SQL Browser Service. For SQL Server you need to open TCP Port 1433 (if you are using the default port for SQL Server) and very importantly for the SQL Browser Service you need to open UDP Port 1434. Name these two rules suitably in your firewall
7. Stop and restart the SQL Server Service using either SSCM or the Services.msc snap-in
8. In the Services.msc snap-in make sure SQL Browser Service Startup Type is Automatic and then start this service

At this point you should be able to connect remotely, using SQL Authentication, user "sqlUser" password "sql" to the SQL Express instance configured as above. A final tip and easy way to check this out is to create an empty text file with the .UDL extension, say "Test.UDL" on your desktop. Double-clicking to edit this file invokes the Microsoft Data Link Properties dialog with which you can quickly test your remote SQL connection

I've found a way to validate a modalpopup without a postback.

In the ModalPopupExtender I set the OnOkScript to a function e.g ValidateBeforePostBack(), then in the function I call Page_ClientValidate for the validation group I want, do a check and if it fails, keep the modalpopup showing. If it passes, I call __doPostBack.

function ValidateBeforePostBack(){ 
     Page_ClientValidate('MyValidationGroupName'); 
     if (Page_IsValid) { __doPostBack('',''); } 
     else { $find('mpeBehaviourID').show(); } 
}

You are right about HashTable, you can forget about it.

Your article mentions the fact that while HashTable and the synchronized wrapper class provide basic thread-safety by only allowing one thread at a time to access the map, this is not 'true' thread-safety since many compound operations still require additional synchronization, for example:

synchronized (records) {
  Record rec = records.get(id);
  if (rec == null) {
      rec = new Record(id);
      records.put(id, rec);
  }
  return rec;
}

However, don't think that ConcurrentHashMap is a simple alternative for a HashMap with a typical synchronized block as shown above. Read this article to understand its intricacies better.

CUDA is after some header modifications compatible with gcc4.7 and maybe higher version: https://www.udacity.com/wiki/cs344/troubleshoot_gcc47

You can use COM, or P/Invoke from .Net, to open the Winspool.drv driver and send bytes directly to devices. But you don't want to do that; this typically works only for the one device on the one version of the one driver you test with, and breaks on everything else. Take this from long, painful, personal experience.

What you want to do is get a barcode font or library that draws barcodes using plain old GDI or GDI+ commands; there's one for .Net here. This works on all devices, even after Zebra changes the driver.

I had the same problem. Turns out I was using UIAlerts that needed the main queue. But, they've been deprecated.
When I changed the UIAlerts to the UIAlertController, I no longer had the problem and did not have to use any dispatch_async code. The lesson - pay attention to warnings. They help even when you don't expect it.

git reset --soft HEAD~1

Reset will rewind your current HEAD branch to the specified revision.

Note the --soft flag: this makes sure that the changes in undone revisions are preserved. After running the command, you'll find the changes as uncommitted local modifications in your working copy.

If you don't want to keep these changes, simply use the --hard flag. Be sure to only do this when you're sure you don't need these changes anymore.

 git reset --hard HEAD~1

Undoing Multiple Commits

git reset --hard 0ad5a7a6

Keep in mind, however, that using the reset command undoes all commits that came after the one you returned to:

Sounds easier to do with the standard classes:

std::complex<double> vecA(0,1);
std::complex<double> i(0,1); // 90 degrees
std::complex<double> r45(sqrt(2.0),sqrt(2.0));
vecA *= i;
vecA *= r45;

Vector rotation is a subset of complex multiplication. To rotate over an angle alpha, you multiply by std::complex<double> { cos(alpha), sin(alpha) }

I combie the code above to this code work for most case. Pass the HttpServletRequest request you get from the api to the method

Put the part from BEGIN....END{} inside a file and name it like my.awk.

And then execute it like below:

awk -f my.awk life.csv >output.txt

Also I see a field separator as ,. You can add that in the begin block of the .awk file as FS=","

I have the same problem now , I have foreign key and i need put it as nullable, to solve this problem you should put

    modelBuilder.Entity<Country>()
        .HasMany(c => c.Users)
        .WithOptional(c => c.Country)
        .HasForeignKey(c => c.CountryId)
        .WillCascadeOnDelete(false);

in DBContext class I am sorry for answer you very late :)

I got the same issue, but i solved it with changing my Grunt.js to Gruntfile.js Check your file name before typing grunt.cmd on windows cmd (if you're using windows).

In the iframe: So that means you have to add some code in the iframe page. Simply add this script to your code IN THE IFRAME:

<body onload="parent.alertsize(document.body.scrollHeight);">

In the holding page: In the page holding the iframe (in my case with ID="myiframe") add a small javascript:

<script>
function alertsize(pixels){
    pixels+=32;
    document.getElementById('myiframe').style.height=pixels+"px";
}
</script>

What happens now is that when the iframe is loaded it triggers a javascript in the parent window, which in this case is the page holding the iframe.

To that JavaScript function it sends how many pixels its (iframe) height is.

The parent window takes the number, adds 32 to it to avoid scrollbars, and sets the iframe height to the new number.

That's it, nothing else is needed.

But if you like to know some more small tricks keep on reading...

DYNAMIC HEIGHT IN THE IFRAME? If you like me like to toggle content the iframe height will change (without the page reloading and triggering the onload). I usually add a very simple toggle script I found online:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
}
</script>

to that script just add:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
    parent.alertsize(document.body.scrollHeight); // ADD THIS LINE!
}
</script>

How you use the above script is easy:

<a href="javascript:toggle('moreheight')">toggle height?</a><br />
<div style="display:none;" id="moreheight">
more height!<br />
more height!<br />
more height!<br />
</div>

For those that like to just cut and paste and go from there here is the two pages. In my case I had them in the same folder, but it should work cross domain too (I think...)

Demo

This isn't really possible in HTML unless you use absolute positioning or javascript. So one solution would be to give this CSS to #bottom_link:

#bottom_link {
    position:absolute;
    bottom:0;
}

Otherwise you'd have to use some javascript. Here's a jQuery block that should do the trick, depending on the simplicity of the page.

$('#bottom_link').css({
    position: 'relative',
    top: $(this).parent().height() - $(this).height()
});

You guys should also make sure that when you override onLayout you HAVE to call super.onLayout with all of the properties, or the view will not be inflated!

If you want an actual boolean column:

ALTER TABLE users ADD "priv_user" boolean DEFAULT false;

Just use a JSON field that these third-party packages provide:

• django-jsonfield
• django-annoying

In this case, you don't need to care about the field value serialization - it'll happen under-the-hood.

Hope that helps.

There is an article with a working idea on how to request oAuth authorization before loading static content dynamically:

Securing Site That Runs on Github Pages With JSON Backend In Private Repository

Content should be stored in a secret GitHub repository with a viewer having read access to it. GitHub pages stores only the serving JS code.

I have found the answer here: http://www.webdesignerdepot.com/2012/11/how-to-create-a-simple-css3-tooltip/

my own code goes like this, I have changed the attribute name, if you maintain the title name for the attribute you end up having two popups for the same text, another change is that my text on hovering displays underneath the exposed text.

.tags {
  display: inline;
  position: relative;
}

.tags:hover:after {
  background: #333;
  background: rgba(0, 0, 0, .8);
  border-radius: 5px;
  bottom: -34px;
  color: #fff;
  content: attr(gloss);
  left: 20%;
  padding: 5px 15px;
  position: absolute;
  z-index: 98;
  width: 350px;
}

.tags:hover:before {
  border: solid;
  border-color: #333 transparent;
  border-width: 0 6px 6px 6px;
  bottom: -4px;
  content: "";
  left: 50%;
  position: absolute;
  z-index: 99;
}

I needed to install various JetBrains tools on a number of machines from CLI, so I wrote a tiny tool to help with that. It also uses cleaner APIs from JB making it hopefully more stable, and works for various JB tools.

Feel free to try it: https://github.com/MarcinZukowski/jetbrains-installer

Loop over the file to read lines:

with open('somefile') as openfileobject:
    for line in openfileobject:
        do_something()

File objects are iterable and yield lines until EOF. Using the file object as an iterable uses a buffer to ensure performant reads.

You can do the same with the stdin (no need to use raw_input():

import sys

for line in sys.stdin:
    do_something()

To complete the picture, binary reads can be done with:

from functools import partial

with open('somefile', 'rb') as openfileobject:
    for chunk in iter(partial(openfileobject.read, 1024), b''):
        do_something()

where chunk will contain up to 1024 bytes at a time from the file, and iteration stops when openfileobject.read(1024) starts returning empty byte strings.

I am using Visual Studio 2010.

This happened to me when I installed .NET 4.5. Uninstall of .NET 4.5 and install of .NET 4.0 helped me and error messages disappeared.

pip install str2bool

>>> from str2bool import str2bool

True
>>> str2bool('FaLsE')
False

There are 3 ways:

First way

You need specify the directory to store mysql data on your host machine. You can then remove the data container. Your mysql data will be saved on you local filesystem.

Mysql container definition must look like this:

mysql:
  container_name: flask_mysql
  restart: always
  image: mysql:latest
  environment:
    MYSQL_ROOT_PASSWORD: 'test_pass' # TODO: Change this
    MYSQL_USER: 'test'
    MYSQL_PASS: 'pass'
volumes:
 - /opt/mysql_data:/var/lib/mysql
ports:
  - "3306:3306"

Second way

Would be to commit the data container before typing docker-compose down:

docker commit my_data_container
docker-compose down

Third way

Also you can use docker-compose stop instead of docker-compose down (then you don't need to commit the container)

You could always use typeof in the if statement. It is better than working with string values like the answer of Natarajan.

if (dt.Columns[0].DataType == typeof(DateTime))
{
}

Update:

In Python 3.8, the prod function was added to the math module. See: math.prod().

Older info: Python 3.7 and prior

The function you're looking for would be called prod() or product() but Python doesn't have that function. So, you need to write your own (which is easy).

Pronouncement on prod()

Yes, that's right. Guido rejected the idea for a built-in prod() function because he thought it was rarely needed.

Alternative with reduce()

As you suggested, it is not hard to make your own using reduce() and operator.mul():

from functools import reduce  # Required in Python 3
import operator
def prod(iterable):
    return reduce(operator.mul, iterable, 1)

>>> prod(range(1, 5))
24

Note, in Python 3, the reduce() function was moved to the functools module.

Specific case: Factorials

As a side note, the primary motivating use case for prod() is to compute factorials. We already have support for that in the math module:

>>> import math

>>> math.factorial(10)
3628800

Alternative with logarithms

If your data consists of floats, you can compute a product using sum() with exponents and logarithms:

>>> from math import log, exp

>>> data = [1.2, 1.5, 2.5, 0.9, 14.2, 3.8]
>>> exp(sum(map(log, data)))
218.53799999999993

>>> 1.2 * 1.5 * 2.5 * 0.9 * 14.2 * 3.8
218.53799999999998

Note, the use of log() requires that all the inputs are positive.

In my testing, both Hans Kesting's and Fredrik Mörk's solutions gave the same answer. But:

I found an interesting discrepancy in the answer using the methods of Raj More and Hans Kesting, and thought I'd share. Thanks to both though for their help; I can't believe such a method is not built into the framework.

Please note that Raj didn't write code and therefore my implementation could be different than he meant.

The difference I found was that the method from Raj More would often be two pixels greater (in both X and Y) than the method from Hans Kesting. I have not yet determined why this occurs. I'm pretty sure it has something to do with the fact that there seems to be a two-pixel border around the contents of a Windows form (as in, inside the form's outermost borders). In my testing, which was certainly not exhaustive to any extent, I've only come across it on controls that were nested. However, not all nested controls exhibit it. For example, I have a TextBox inside a GroupBox which exhibits the discrepancy, but a Button inside the same GroupBox does not. I cannot explain why.

Note that when the answers are equivalent, they consider the point (0, 0) to be inside the content border I mentioned above. Therefore I believe I'll consider the solutions from Hans Kesting and Fredrik Mörk to be correct but don't think I'll trust the solution I've implemented of Raj More's.

I also wondered exactly what code Raj More would have written, since he gave an idea but didn't provide code. I didn't fully understand the PointToScreen() method until I read this post: http://social.msdn.microsoft.com/Forums/en-US/netfxcompact/thread/aa91d4d8-e106-48d1-8e8a-59579e14f495

Here's my method for testing. Note that 'Method 1' mentioned in the comments is slightly different than Hans Kesting's.

private Point GetLocationRelativeToForm(Control c)
{
  // Method 1: walk up the control tree
  Point controlLocationRelativeToForm1 = new Point();
  Control currentControl = c;
  while (currentControl.Parent != null)
  {
    controlLocationRelativeToForm1.Offset(currentControl.Left, currentControl.Top);
    currentControl = currentControl.Parent;
  }

  // Method 2: determine absolute position on screen of control and form, and calculate difference
  Point controlScreenPoint = c.PointToScreen(Point.Empty);
  Point formScreenPoint = PointToScreen(Point.Empty);
  Point controlLocationRelativeToForm2 = controlScreenPoint - new Size(formScreenPoint);

  // Method 3: combine PointToScreen() and PointToClient()
  Point locationOnForm = c.FindForm().PointToClient(c.Parent.PointToScreen(c.Location));

  // Theoretically they should be the same
  Debug.Assert(controlLocationRelativeToForm1 == controlLocationRelativeToForm2);
  Debug.Assert(locationOnForm == controlLocationRelativeToForm1);
  Debug.Assert(locationOnForm == controlLocationRelativeToForm2);

  return controlLocationRelativeToForm1;
}

I was experiencing this segmentation fault after upgrading dlib on RPI. I tracebacked the stack as suggested by Shiplu Mokaddim above and it settled on an OpenBLAS library.

Since OpenBLAS is also multi-threaded, using it in a muilt-threaded application will exponentially multiply threads until segmentation fault. For multi-threaded applications, set OpenBlas to single thread mode.

In python virtual environment, tell OpenBLAS to only use a single thread by editing:

    $ workon <myenv>
    $ nano .virtualenv/<myenv>/bin/postactivate

and add:

    export OPENBLAS_NUM_THREADS=1 
    export OPENBLAS_MAIN_FREE=1

After reboot I was able to run all my image recognition apps on rpi3b which were previously crashing it.

But in my opinion one important thing.

The "char(number)" it's lenght of variable.

If we've got table with "Names" like for example [Test1..Test200] and we declare char(5) in SELECT like:

DECLARE @variable char(5)
SET @variable = 'Test1%'
SELECT * FROM table WHERE Name like @variable

the result will be only - "Test1"! (char(5) - 5 chars in lenght; Test11 is 6 )

The rest of potential interested data like [Test11..Test200] will not be returned in the result.

It's ok if we want to limit the SELECT by this way. But if it's not intentional way of doing it could return incorrect results from planned ( Like "all Names begining with Test1..." ).

In my opinion if we don't know the precise lenght of a SELECTed value, a better solution could be something like this one:

DECLARE @variable varchar(max)
SET @variable = 'Test1%'
SELECT * FROM <table> WHERE variable1 like @variable

This returns (Test1 but also Test11..Test19 and Test100..Test199).

@RestController is the combination of @Controller and @ResponseBody.

Flow of request in a @Controller class without using a @ResponseBody annotation:

@RestController returns an object as response instead of view.

Floating point numbers (IEEE 754) are symmetrical, so if you can represent the greatest value (DBL_MAX or numeric_limits<double>::max()), just prepend a minus sign.

And then is the cool way:

double f;
(*((long long*)&f))= ~(1LL<<52);

I do not know whether this is the general opinion, but I've always differentiated the two by what they are used for. An emulator is used if you actually want to use the emulated machine for its output. A simulator, on the other hand, is for when you want to study the simulated machine or test its behaviour.

For example, if you want to write some state machine logic in your application (which is running on a general purpose CPU), you write a small state machine emulator. If you want to study the efficiency or viability of a state machine for a particular problem, you write a simulator.

I had a similar issue I was getting the entire object in this but the value was displaying while doing #each.

Solution: I re-structure my array of object like this:

let list = results.map((item)=>{
    return { name:item.name, author:item.author }
});

and then in template file:

{{#each list}}
    <tr>
        <td>{{name }}</td>
        <td>{{author}}</td>      
    </tr>
{{/each}} 

/.*/ works great if there are no line breaks. If it has to match line breaks, here are some solutions:

package com.mycompany;

import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 2, max = 14)
    private String licensePlate;

    @Min(2)
    private int seatCount;

    public Car(String manufacturer, String licencePlate, int seatCount) {
        this.manufacturer = manufacturer;
        this.licensePlate = licencePlate;
        this.seatCount = seatCount;
    }

    //getters and setters ...
}

@NotNull, @Size and @Min are so-called constraint annotations, that we use to declare constraints, which shall be applied to the fields of a Car instance:

manufacturer shall never be null

licensePlate shall never be null and must be between 2 and 14 characters long

seatCount shall be at least 2.

Suggest do this in your code-behind before sending down to SQL Server.

 int userVal = int.Parse(txtboxname.Text);

Perhaps try to parse and optionally let the user know.

int? userVal;
if (int.TryParse(txtboxname.Text, out userVal) 
{
  DoSomething(userVal.Value);
}
else
{ MessageBox.Show("Hey, we need an int over here.");   }

The exception you note means that you're not including the value in the call to the stored proc. Try setting a debugger breakpoint in your code at the time you call down into the code that builds the call to SQL Server.

Ensure you're actually attaching the parameter to the SqlCommand.

using (SqlConnection conn = new SqlConnection(connString))
{
    SqlCommand cmd = new SqlCommand(sql, conn);
    cmd.Parameters.Add("@ParamName", SqlDbType.Int);
    cmd.Parameters["@ParamName"].Value = newName;        
    conn.Open();
    string someReturn = (string)cmd.ExecuteScalar();        
}

Perhaps fire up SQL Profiler on your database to inspect the SQL statement being sent/executed.

ActionBar actionBar = getSupportActionBar();
actionBar.setTitle(getString(R.string.titolo));
actionBar.setIcon(R.mipmap.ic_launcher);
actionBar.setDisplayShowHomeEnabled(true);

While what you want to accomplish may be useful, there is another option which I believe you might be overlooking that is much more simple.

You are correct, the Bootstrap tables act strangely when you have columns which are not fixed height. However, there is a bootstrap class created to combat this issue and perform responsive resets.

simply create an empty <div class="clearfix"></div> before the start of each new row to allow the floats to reset and the columns to return to their correct positions.

here is a bootply.

This is insanely awesome and even covers HTTPS with pretty domain names:

The really awesome parts I couldn't find anywhere else on SO in case the above link ever goes away:

> C:\Program Files (x86)\IIS Express>IisExpressAdminCmd.exe Usage:
> iisexpressadmincmd.exe <command> <parameters> Supported commands:

>       setupSslUrl -url:<url> -CertHash:<value>

> -url:http://contoso:80/ 2) Remove "http.sys" configuration and "hosts" file entry for the friendly  hostname "contoso": iisexpressadmincmd
> deleteFriendlyHostnameUrl -url:http://contoso:80/

The above utility will register the SSL certificate for you! If you use the -UseSelfSigned option, it's super easy.

If you want to do things the hard way, the non-obvious part is you need to tell HTTP.SYS what certificate to use, like this:

netsh http add sslcert ipport=0.0.0.0:443 appid={214124cd-d05b-4309-9af9-9caa44b2b74a} certhash=YOURCERTHASHHERE

Certhash is the "Thumbprint" you can get from the certificate properties in MMC.

If your class extends Serializable, you can write and read objects through a ByteArrayOutputStream, that's what I usually do.

Simple way to do this. Try this code. Put code in your htaccess file:

Options +FollowSymLinks

RewriteEngine on

RewriteRule profile/(.*)/ profile.php?u=$1

RewriteRule profile/(.*) profile.php?u=$1   

It will create this type pretty URL:

http://www.domain.com/profile/12345/

Any reason they can't just click on the tab for your sheet when they want it?

Like Nikolay said do that in onPrepareOptionsMenu().

For menu items in the action bar you have to invalidate the menu with activity.invalidateOptionsMenu();

This is descriped in more detail here How can I refresh the ActionBar when onPrepareOptionsMenu switched menu entries?

Make a module, service and component in particular module

Basic:

    ng g module chat     
    ng g service chat/chat -m chat
    ng g component chat/chat-dialog -m chat

    In chat.module.ts:
        exports: [ChatDialogComponent],
        providers: [ChatService]

    In app.module.ts:

        imports: [
            BrowserModule,
            ChatModule
        ]

    Now in app.component.html:
        <chat-dialog></chat-dialog>


LAZY LOADING:
    ng g module pages --module app.module --route pages

        CREATE src/app/pages/pages-routing.module.ts (340 bytes)
        CREATE src/app/pages/pages.module.ts (342 bytes)
        CREATE src/app/pages/pages.component.css (0 bytes)
        CREATE src/app/pages/pages.component.html (20 bytes)
        CREATE src/app/pages/pages.component.spec.ts (621 bytes)
        CREATE src/app/pages/pages.component.ts (271 bytes)
        UPDATE src/app/app-routing.module.ts (8611 bytes)       

    ng g module pages/forms --module pages/pages.module --route forms

        CREATE src/app/forms/forms-routing.module.ts (340 bytes)
        CREATE src/app/forms/forms.module.ts (342 bytes)
        CREATE src/app/forms/forms.component.css (0 bytes)
        CREATE src/app/forms/forms.component.html (20 bytes)
        CREATE src/app/forms/forms.component.spec.ts (621 bytes)
        CREATE src/app/forms/forms.component.ts (271 bytes)
        UPDATE src/app/pages/pages-routing.module.ts (437 bytes)

Try this code:

preg_match('/[a-zA-Z]+<\/a>.$/', $lastgame, $match);
print_r($match);

Using / as a delimiter means you also need to escape it here, like so: <\/a>.

UPDATE

preg_match('/<a.*<a.*>(.*)</', $lastgame, $match);
echo'['.$match[1].']';

Might not be the best way...

Just to add a third option:

require(doBy)
summaryBy(Frequency~Category, data=yourdataframe, FUN=sum)

EDIT: this is a very old answer. Now I would recommend the use of group_by and summarise from dplyr, as in @docendo answer.

I am late for the party. Try replacing as below, mine worked perfectly- "DOMDocument" to "MSXML2.DOMDocument60" "XMLHTTP" to "MSXML2.XMLHTTP60"

You need to use wildards (.*) before and after to replace the whole line:

sed 's/.*TEXT_TO_BE_REPLACED.*/This line is removed by the admin./'

1. Why does the getOne(id) method fail?

See this section in the docs. You overriding the already in place transaction might be causing the issue. However, without more info this one is difficult to answer.

2. When I should use the getOne(id) method?

Without digging into the internals of Spring Data JPA, the difference seems to be in the mechanism used to retrieve the entity.

If you look at the JavaDoc for getOne(ID) under See Also:

See Also:
EntityManager.getReference(Class, Object)

it seems that this method just delegates to the JPA entity manager's implementation.

However, the docs for findOne(ID) do not mention this.

The clue is also in the names of the repositories. JpaRepository is JPA specific and therefore can delegate calls to the entity manager if so needed. CrudRepository is agnostic of the persistence technology used. Look here. It's used as a marker interface for multiple persistence technologies like JPA, Neo4J etc.

So there's not really a 'difference' in the two methods for your use cases, it's just that findOne(ID) is more generic than the more specialised getOne(ID). Which one you use is up to you and your project but I would personally stick to the findOne(ID) as it makes your code less implementation specific and opens the doors to move to things like MongoDB etc. in the future without too much refactoring :)

By using (,), you are capturing the group, if you simply remove them you will not have this problem.

>>> str1 = "a    b     c      d"
>>> re.split(" +", str1)
['a', 'b', 'c', 'd']

However there is no need for regex, str.split without any delimiter specified will split this by whitespace for you. This would be the best way in this case.

>>> str1.split()
['a', 'b', 'c', 'd']

If you really wanted regex you can use this ('\s' represents whitespace and it's clearer):

>>> re.split("\s+", str1)
['a', 'b', 'c', 'd']

or you can find all non-whitespace characters

>>> re.findall(r'\S+',str1)
['a', 'b', 'c', 'd']

This could be handy for you... It's to create a temp. folder and return it as a string in VB.NET.

Easily convertible to C#:

Public Function GetTempDirectory() As String
    Dim mpath As String
    Do
        mpath = System.IO.Path.Combine(System.IO.Path.GetTempPath, System.IO.Path.GetRandomFileName)
    Loop While System.IO.Directory.Exists(mpath) Or System.IO.File.Exists(mpath)
    System.IO.Directory.CreateDirectory(mpath)
    Return mpath
End Function

I think I found a simple solution after a lot of irritation :

if elem in string_list:
    counter = 0
    elem_pos = []
    for i in string_list:
        if i == elem:
            elem_pos.append(counter)
        counter = counter + 1
    print(elem_pos)

This prints a list giving you the indexes of a specific element ("elem")

Javascript doesn't have "associative arrays" the way you're thinking of them. Instead, you simply have the ability to set object properties using array-like syntax (as in your example), plus the ability to iterate over an object's properties.

The upshot of this is that there is no guarantee as to the order in which you iterate over the properties, so there is nothing like a sort for them. Instead, you'll need to convert your object properties into a "true" array (which does guarantee order). Here's a code snippet for converting an object into an array of two-tuples (two-element arrays), sorting it as you describe, then iterating over it:

var tuples = [];

for (var key in obj) tuples.push([key, obj[key]]);

tuples.sort(function(a, b) {
    a = a[1];
    b = b[1];

    return a < b ? -1 : (a > b ? 1 : 0);
});

for (var i = 0; i < tuples.length; i++) {
    var key = tuples[i][0];
    var value = tuples[i][1];

    // do something with key and value
}

You may find it more natural to wrap this in a function which takes a callback:

function bySortedValue(obj, callback, context) {_x000D_
  var tuples = [];_x000D_
_x000D_
  for (var key in obj) tuples.push([key, obj[key]]);_x000D_
_x000D_
  tuples.sort(function(a, b) {_x000D_
    return a[1] < b[1] ? 1 : a[1] > b[1] ? -1 : 0_x000D_
  });_x000D_
_x000D_
  var length = tuples.length;_x000D_
  while (length--) callback.call(context, tuples[length][0], tuples[length][1]);_x000D_
}_x000D_
_x000D_
bySortedValue({_x000D_
  foo: 1,_x000D_
  bar: 7,_x000D_
  baz: 3_x000D_
}, function(key, value) {_x000D_
  document.getElementById('res').innerHTML += `${key}: ${value}<br>`_x000D_
});

<p id='res'>Result:<br/><br/><p>

Remove this from #info:

    margin-left:auto;

Add this for your header:

#info p {
    text-align: center;
}

Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align.

Sample
http://jsfiddle.net/Vc8CB/

If you're open to a PHP solution:

<td><img src='<?PHP
  $path1 = "path/to/your/image.jpg";
  $path2 = "alternate/path/to/another/image.jpg";

  echo file_exists($path1) ? $path1 : $path2; 
  ?>' alt='' />
</td>

////EDIT OK, here's a JS version:

<table><tr>
<td><img src='' id='myImage' /></td>
</tr></table>

<script type='text/javascript'>
  document.getElementById('myImage').src = "newImage.png";

  document.getElementById('myImage').onload = function() { 
    alert("done"); 
  }

  document.getElementById('myImage').onerror = function() { 
    alert("Inserting alternate");
    document.getElementById('myImage').src = "alternate.png"; 
  }
</script>

I had the same problem with something like

@foreach (var item in Model)
{
    @Html.DisplayFor(m => !item.IsIdle, "BoolIcon")
}

I solved this just by doing

@foreach (var item in Model)
{
    var active = !item.IsIdle;
    @Html.DisplayFor(m => active , "BoolIcon")
}

When you know the trick, it's simple.

The difference is that, in the first case, I passed a method as a parameter whereas in the second case, it's an expression.
