Late to the party, MY two cents are given below after some research. During logout, make sure following things are happening...

Clear the client storage/session

Update the user table last login date-time and logout date-time whenever login or logout happens respectively. So login date time always should be greater than logout (Or keep logout date null if the current status is login and not yet logged out)

This is way far simple than keeping additional table of blacklist and purging regularly. Multiple device support requires additional table to keep loggedIn, logout dates with some additional details like OS-or client details.

I had this problem every time I deployed a new website or updated an existing one using MSDeploy.

I was able to fix this by unloading the app domain using MSDeploy with the following syntax:

msdeploy.exe -verb:sync -source:recycleApp -dest:recycleApp="Default Web Site/myAppName",recycleMode=UnloadAppDomain

You can also stop, start, or recycle the application pool - more details here: http://technet.microsoft.com/en-us/library/ee522997%28v=ws.10%29.aspx

While Armaan's solution helped get me unstuck, it did not make the problem go away permanently.

It is probably worth adding that an insert iterator of any kind (std::back_insert_iterator, std::front_insert_iterator, std::insert_iterator) is guaranteed to remain valid as long as all insertions are performed through this iterator and no other independent iterator-invalidating event occurs.

For example, when you are performing a series of insertion operations into a std::vector by using std::insert_iterator it is quite possible that these insertions will trigger vector reallocation, which will invalidate all iterators that "point" into that vector. However, the insert iterator in question is guaranteed to remain valid, i.e. you can safely continue the sequence of insertions. There's no need to worry about triggering vector reallocation at all.

This, again, applies only to insertions performed through the insert iterator itself. If iterator-invalidating event is triggered by some independent action on the container, then the insert iterator becomes invalidated as well in accordance with the general rules.

For example, this code

std::vector<int> v(10);
std::vector<int>::iterator it = v.begin() + 5;
std::insert_iterator<std::vector<int> > it_ins(v, it);

for (unsigned n = 20; n > 0; --n)
  *it_ins++ = rand();

is guaranteed to perform a valid sequence of insertions into the vector, even if the vector "decides" to reallocate somewhere in the middle of this process. Iterator it will obviously become invalid, but it_ins will continue to remain valid.

If you are using a class from another project, the project needs to re-build and create re-the dll. Make sure "Build" is checked for that project on Build -> Configuration Manager in Visual Studio. So the reference project will re-build and update the dll.

You want sessions if you have data you want to have the data held for longer than one page.

$_GET for just one page.

<a href='page.php?var=data'>Data link</a>

on page.php

<?php
echo $_GET['var'];
?>

will output: data

There is no Javascript API to send ping frames or receive pong frames. This is either supported by your browser, or not. There is also no API to enable, configure or detect whether the browser supports and is using ping/pong frames. There was discussion about creating a Javascript ping/pong API for this. There is a possibility that pings may be configurable/detectable in the future, but it is unlikely that Javascript will be able to directly send and receive ping/pong frames.

However, if you control both the client and server code, then you can easily add ping/pong support at a higher level. You will need some sort of message type header/metadata in your message if you don't have that already, but that's pretty simple. Unless you are planning on sending pings hundreds of times per second or have thousands of simultaneous clients, the overhead is going to be pretty minimal to do it yourself.

If you don't mind a third party dependency, there is a class named Collectors2 in Eclipse Collections which contains methods returning Collectors for summing and summarizing BigDecimal and BigInteger. These methods take a Function as a parameter so you can extract a BigDecimal or BigInteger value from an object.

List<BigDecimal> list = mList(
        BigDecimal.valueOf(0.1),
        BigDecimal.valueOf(1.1),
        BigDecimal.valueOf(2.1),
        BigDecimal.valueOf(0.1));

BigDecimal sum =
        list.stream().collect(Collectors2.summingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), sum);

BigDecimalSummaryStatistics statistics =
        list.stream().collect(Collectors2.summarizingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), statistics.getSum());
Assert.assertEquals(BigDecimal.valueOf(0.1), statistics.getMin());
Assert.assertEquals(BigDecimal.valueOf(2.1), statistics.getMax());
Assert.assertEquals(BigDecimal.valueOf(0.85), statistics.getAverage());

Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.

Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).

Django 1.4.1

Python 2.7.3

#Model
class MonthEnd(models.Model):
    report = models.FileField(db_index=True, upload_to='not_used')

import csv
from os.path import join

#build and store the file
def write_csv():
    path = join(settings.MEDIA_ROOT, 'files', 'month_end', 'report.csv')
    f = open(path, "w+b")

    #wipe the existing content
    f.truncate()

    csv_writer = csv.writer(f)
    csv_writer.writerow(('col1'))

    for num in range(3):
        csv_writer.writerow((num, ))

    month_end_file = MonthEnd()
    month_end_file.report.name = path
    month_end_file.save()

from my_app.models import MonthEnd

#serve it up as a download
def get_report(request):
    month_end = MonthEnd.objects.get(file_criteria=criteria)

    response = HttpResponse(month_end.report, content_type='text/plain')
    response['Content-Disposition'] = 'attachment; filename=report.csv'

    return response

I used the below method to migrate my GIT Stash to GitLab by maintaining all branches and commit history.

Clone the old repository to local.

git clone --bare <STASH-URL>

Create an empty repository in GitLab.

git push --mirror <GitLab-URL>

FrameLayout is not the better way to do this:

Use RelativeLayout instead. You can position the elements anywhere you like. The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).

Example:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimary"
        app:srcCompat="@drawable/ic_information"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is a text."
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="8dp"
        android:padding="5dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:background="#A000"
        android:textColor="@android:color/white"/>
</RelativeLayout>

According to the Material design guidelines (here, under "DP unit grid"), your product icon should be of size 48 dp, with a padding of 1dp, except for the case of XXXHDPI, where the padding should be 4dp.

So, in pixels, the sizes are:

• 48 × 48 (mdpi) , with 1 dp padding
• 72 × 72 (hdpi), with 1 dp padding
• 96 × 96 (xhdpi), with 1 dp padding
• 144 × 144 (xxhdpi), with 1 dp padding
• 192 × 192 (xxxhdpi) , with 4 dp padding

I recommend to avoid using VectorDrawable as some launchers don't support it, but I think WEBP should be ok as long as you have your minSdk support transparency for them (API 18 and above - Android 4.3).

If you publish on the Play Store, the requirement to what to upload there are (based on here) :

• 32-bit PNG (with alpha)
• Dimensions: 512px by 512px
• Maximum file size: 1024KB

These days, you should use the flexbox method (may be adapted to all browsers with a browser prefix).

.container {
    display: flex;
}

.left {
    width: 180px;
}

.right {
    flex-grow: 1;
}

The nature of wanting to include the row where A == 5 and all rows upto but not including the row where A == 8 means we will end up using iloc (loc includes both ends of slice).

In order to get the index labels we use idxmax. This will return the first position of the maximum value. I run this on a boolean series where A == 5 (then when A == 8) which returns the index value of when A == 5 first happens (same thing for A == 8).

Then I use searchsorted to find the ordinal position of where the index label (that I found above) occurs. This is what I use in iloc.

i5, i8 = df.index.searchsorted([df.A.eq(5).idxmax(), df.A.eq(8).idxmax()])
df.iloc[i5:i8]

numpy

you can further enhance this by using the underlying numpy objects the analogous numpy functions. I wrapped it up into a handy function.

def find_between(df, col, v1, v2):
    vals = df[col].values
    mx1, mx2 = (vals == v1).argmax(), (vals == v2).argmax()
    idx = df.index.values
    i1, i2 = idx.searchsorted([mx1, mx2])
    return df.iloc[i1:i2]

find_between(df, 'A', 5, 8)

timing

Note that usage of a SerialPort.DataReceived event is optional. You can set proper timeout using SerialPort.ReadTimeout and continuously call SerialPort.Read() after you wrote something to a port until you get a full response.

Moreover you can use SerialPort.BaseStream property to extract an underlying Stream instance. The benefit of using a Stream is that you can easily utilize various decorators with it:

var port = new SerialPort();
// LoggingStream inherits Stream, implements IDisposable, needen abstract methods and 
// overrides needen virtual methods. 
Stream portStream = new LoggingStream(port.BaseStream);
portStream.Write(...); // Logs write buffer.
portStream.Read(...); // Logs read buffer.

For more information check:

On the most part, I'd say follow the pattern. I have deviated from it, but very rarely, and for specific reasons. In the case in point, the biggest issue I'd have is that I'd probably still use an Action<SomeObjectType>, allowing me to add extra properties later, and to use the occasional 2-way property (think Handled, or other feedback-events where the subscriber needs to to set a property on the event object). And once you've started down that line, you might as well use EventHandler<T> for some T.

Try this,

def get_dic_from_two_lists(keys, values):
    return { keys[i] : values[i] for i in range(len(keys)) }

Assume we have two lists country and capital

country = ['India', 'Pakistan', 'China']
capital = ['New Delhi', 'Islamabad', 'Beijing']

Then create dictionary from the two lists:

print get_dic_from_two_lists(country, capital)

The output is like this,

{'Pakistan': 'Islamabad', 'China': 'Beijing', 'India': 'New Delhi'}

checkout this article :http://www.morgantechspace.com/2013/08/convert-object-to-byte-array-and-vice.html

Use the below code

// Convert an object to a byte array
private byte[] ObjectToByteArray(Object obj)
{
    if(obj == null)
        return null;

    BinaryFormatter bf = new BinaryFormatter();
    MemoryStream ms = new MemoryStream();
    bf.Serialize(ms, obj);

    return ms.ToArray();
}

// Convert a byte array to an Object
private Object ByteArrayToObject(byte[] arrBytes)
{
    MemoryStream memStream = new MemoryStream();
    BinaryFormatter binForm = new BinaryFormatter();
    memStream.Write(arrBytes, 0, arrBytes.Length);
    memStream.Seek(0, SeekOrigin.Begin);
    Object obj = (Object) binForm.Deserialize(memStream);

    return obj;
}

docker ps -s will show the size of running containers only.

To check the size of all containers use docker ps -as

You can use list slicing to archive your goal:

n = 5
mylist = [1,2,3,4,5,6,7,8,9]
newlist = mylist[n:]
print newlist

Outputs:

[6, 7, 8, 9]

Or del if you only want to use one list:

n = 5
mylist = [1,2,3,4,5,6,7,8,9]
del mylist[:n]
print mylist

Outputs:

[6, 7, 8, 9]

The best way to remove items from a list while iterating over it is to use RemoveAll(). But the main concern written by people is that they have to do some complex things inside the loop and/or have complex compare cases.

The solution is to still use RemoveAll() but use this notation:

var list = new List<int>(Enumerable.Range(1, 10));
list.RemoveAll(item => 
{
    // Do some complex operations here
    // Or even some operations on the items
    SomeFunction(item);
    // In the end return true if the item is to be removed. False otherwise
    return item > 5;
});

If you have a good reason to set aside culture-dependent formatting and get explicit control over whether or not there's a space between the value and the "%", and whether the "%" is leading or trailing, you can use NumberFormatInfo's PercentPositivePattern and PercentNegativePattern properties.

For example, to get a decimal value with a trailing "%" and no space between the value and the "%":

myValue.ToString("P2", new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 });

More complete example:

using System.Globalization; 

...

decimal myValue = -0.123m;
NumberFormatInfo percentageFormat = new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 };
string formattedValue = myValue.ToString("P2", percentageFormat); // "-12.30%" (in en-us)

This is supported by IE too:

HTML

class="disabled"

CSS

.disabled{
...
}

A global Mutex is not only to ensure to have only one instance of an application. I personally prefer using Microsoft.VisualBasic to ensure single instance application like described in What is the correct way to create a single-instance WPF application? (Dale Ragan answer)... I found that's easier to pass arguments received on new application startup to the initial single instance application.

But regarding some previous code in this thread, I would prefer to not create a Mutex each time I want to have a lock on it. It could be fine for a single instance application but in other usage it appears to me has overkill.

That's why I suggest this implementation instead:

Usage:

static MutexGlobal _globalMutex = null;
static MutexGlobal GlobalMutexAccessEMTP
{
    get
    {
        if (_globalMutex == null)
        {
            _globalMutex = new MutexGlobal();
        }
        return _globalMutex;
    }
}

using (GlobalMutexAccessEMTP.GetAwaiter())
{
    ...
}

Check the mozilla documentation on window.open. The window features ("directory=...,...,height=350") etc. arguments should be a string:

window.open('/pageaddress.html','winname',"directories=0,titlebar=0,toolbar=0,location=0,status=0,menubar=0,scrollbars=no,resizable=no,width=400,height=350");

Try if that works in your browsers. Note that some of the features might be overridden by user preferences, such as "location" (see doc.)

I'm not 100% on why (actually came here to search for the answer), but this also works, and doesn't require replacing all nan values.

import pandas as pd
import numpy as np

df = pd.DataFrame([["foo1"], ["foo2"], ["bar"], [np.nan]], columns=['a'])

newdf = df.loc[df['a'].str.contains('foo') == True]

Works with or without .loc.

I have no idea why this works, as I understand it when you're indexing with brackets pandas evaluates whatever's inside the bracket as either True or False. I can't tell why making the phrase inside the brackets 'extra boolean' has any effect at all.

You need to make the object first, then use [] to set it.

var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);

UPDATE 2018:

If you're able to use ES6 and Babel, you can use this new feature:

{
    [yourKeyVariable]: someValueArray,
}  

General rule is the following:

• If select contains single expression and it's an entity, then result is that entity
• If select contains single expression and it's a primitive, then result is that primitive
• If select contains multiple expressions, then result is Object[] containing the corresponding primitives/entities

So, in your case list is a List<Object[]>.

On mobile devices (with Chrome for Android or Opera Mobile) you can detect zoom by window.visualViewport.scale. https://developer.mozilla.org/en-US/docs/Web/API/Visual_Viewport_API

Detect on Safari: document.documentElement.clientWidth / window.innerWidth (return 1 if no zooming on device).

I found a solution that is more efficient than currently accepted answer, because current answer forces all list elements to be refreshed. My solution will refresh only one element (that was touched) by calling adapters getView and recycling current view which adds even more efficiency.

mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
      // Edit object data that is represented in Viewat at list's "position"
      view = mAdapter.getView(position, view, parent);
    }
});

INNER JOIN CTE prev on prev.rownum = cur.rownum - 1

I came here for a reminder of how to set up the query but the existing examples were hard to follow. Here is an example with more explanation.

String having = null;
String orderBy = "column3 DESC";
String limit = "10";

Cursor cursor = db.query(table, columns, selection, selectionArgs, groupBy, having, orderBy, limit);

Parameters

• table: the name of the table you want to query
• columns: the column names that you want returned. Don't return data that you don't need.
• selection: the row data that you want returned from the columns (This is the WHERE clause.)
• selectionArgs: This is substituted for the ? in the selection String above.
• groupBy and having: This groups duplicate data in a column with data having certain conditions. Any unneeded parameters can be set to null.
• orderBy: sort the data
• limit: limit the number of results to return

I know this is an old question, but I stumbled across it when I was having a similar issue, and just wanted to share how I ended achieving the results you requested so future people can pick what works best for their situation.

First, I utilize the onsubmit event in the form, and pass this to the function to make it easier to deal with this particular form.

<form action="/system/wpacert" onsubmit="return closeSelf(this);" method="post" enctype="multipart/form-data"  name="certform">
    <div>Certificate 1: <input type="file" name="cert1"/></div>
    <div>Certificate 2: <input type="file" name="cert2"/></div>
    <div>Certificate 3: <input type="file" name="cert3"/></div>

    <div><input type="submit" value="Upload"/></div>
</form>

In our function, we'll submit the form data, and then we'll close the window. This will allow it to submit the data, and once it's done, then it'll close the window and return you to your original window.

<script type="text/javascript">
  function closeSelf (f) {
     f.submit();
     window.close();
  }
</script>

Hope this helps someone out. Enjoy!

Option 2: This option will let you submit via AJAX, and if it's successful, it'll close the window. This prevents windows from closing prior to the data being submitted. Credits to http://jquery.malsup.com/form/ for their work on the jQuery Form Plugin

First, remove your onsubmit/onclick events from the form/submit button. Place an ID on the form so AJAX can find it.

<form action="/system/wpacert" method="post" enctype="multipart/form-data"  id="certform">
    <div>Certificate 1: <input type="file" name="cert1"/></div>
    <div>Certificate 2: <input type="file" name="cert2"/></div>
    <div>Certificate 3: <input type="file" name="cert3"/></div>

    <div><input type="submit" value="Upload"/></div>
</form>

Second, you'll want to throw this script at the bottom, don't forget to reference the plugin. If the form submission is successful, it'll close the window.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script> 
<script src="http://malsup.github.com/jquery.form.js"></script> 

    <script>
       $(document).ready(function () {
          $('#certform').ajaxForm(function () {
          window.close();
          });
       });
    </script>

Both Tom and Burton's answers work for me eventually, but I had a little trouble figuring out how to apply them to a ModelChoiceField.

The only trick to it is that the choices are stored as tuples of (<model's ID>, <model's unicode repr>), so if you want to set the initial model selection, you pass the model's ID as the initial value, not the object itself or it's name or anything else. Then it's as simple as:

form = EmployeeForm(initial={'manager': manager_employee_id})

Alternatively the initial argument can be ignored in place of an extra line with:

form.fields['manager'].initial = manager_employee_id

You can use the function numpy.nonzero(), or the nonzero() method of an array

import numpy as np

A = np.array([[2,4],
          [6,2]])
index= np.nonzero(A>1)
       OR
(A>1).nonzero()

Output:

(array([0, 1]), array([1, 0]))

First array in output depicts the row index and second array depicts the corresponding column index.

r+ is used for reading, and writing mode. b is for binary. r+b mode is open the binary file in read or write mode.
You can read more here.

The preflight is being triggered by your Content-Type of application/json. The simplest way to prevent this is to set the Content-Type to be text/plain in your case. application/x-www-form-urlencoded & multipart/form-data Content-Types are also acceptable, but you'll of course need to format your request payload appropriately.

If you are still seeing a preflight after making this change, then Angular may be adding an X-header to the request as well.

Or you might have headers (Authorization, Cache-Control...) that will trigger it, see:

• https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS#Preflighted_requests

try this rather than redirect...

Response.Write("<script>");
Response.Write("window.open('ClickPicture.aspx','_blank')");
Response.Write("</script>");

The latest as of release of API 23 is

compile 'com.android.support:design:23.2.1'

This works for me

sed '/^all:/ s/$/ anotherthing/' file

The first part is a pattern to find and the second part is an ordinary sed's substitution using $ for the end of a line.

If you want to change the file during the process, use -i option

sed -i '/^all:/ s/$/ anotherthing/' file

Or you can redirect it to another file

sed '/^all:/ s/$/ anotherthing/' file > output

As of jQuery version 1.1.3, event.which normalizes event.keyCode and event.charCode so you don't have to worry about browser compatibility issues. Documentation on event.which

event.which will give 1, 2 or 3 for left, middle and right mouse buttons respectively so:

$('#element').mousedown(function(event) {
    switch (event.which) {
        case 1:
            alert('Left Mouse button pressed.');
            break;
        case 2:
            alert('Middle Mouse button pressed.');
            break;
        case 3:
            alert('Right Mouse button pressed.');
            break;
        default:
            alert('You have a strange Mouse!');
    }
});

If anybody is just like me willing to use jQuery, but still found himself looking to this question then this may help you guys:

This should work for both strings and unicode objects in Python2, and both strings and bytes in Python3:

# python <3.0
def only_numerics(seq):
    return filter(type(seq).isdigit, seq)

# python =3.0
def only_numerics(seq):
    seq_type= type(seq)
    return seq_type().join(filter(seq_type.isdigit, seq))

This is the right answer you want and this solution i have run my self on netbeans

ArrayList a=new ArrayList();
a.add(1);
a.add(3);
a.add(4);
a.add(5);
a.add(8);
a.add(12);

int b[]= new int [6];
        Integer m[] = new Integer[a.size()];//***Very important conversion to array*****
        m=(Integer[]) a.toArray(m);
for(int i=0;i<a.size();i++)
{
    b[i]=m[i]; 
    System.out.println(b[i]);
}   
    System.out.println(a.size());

As of the current JRE implementation, Function.identity() will always return the same instance while each occurrence of identifier -> identifier will not only create its own instance but even have a distinct implementation class. For more details, see here.

The reason is that the compiler generates a synthetic method holding the trivial body of that lambda expression (in the case of x->x, equivalent to return identifier;) and tell the runtime to create an implementation of the functional interface calling this method. So the runtime sees only different target methods and the current implementation does not analyze the methods to find out whether certain methods are equivalent.

So using Function.identity() instead of x -> x might save some memory but that shouldn’t drive your decision if you really think that x -> x is more readable than Function.identity().

You may also consider that when compiling with debug information enabled, the synthetic method will have a line debug attribute pointing to the source code line(s) holding the lambda expression, therefore you have a chance of finding the source of a particular Function instance while debugging. In contrast, when encountering the instance returned by Function.identity() during debugging an operation, you won’t know who has called that method and passed the instance to the operation.

This is not an plus, but the sign for the binary operator XOR

a   b   a XOR b
0   0   0
0   1   1
1   0   1
1   1   0

A TVF (table-valued function) is supposed to be SELECTed FROM. Try this:

select * from FN('myFunc')

A 'fun' way to learn socket.io is to play BrowserQuest by mozilla and look at its source code :-)

There are three simple ways:

1. By separator:

    s.split("separator")  |  s.split('/')  |  s.split(char::is_numeric)
   

2. By whitespace:

    s.split_whitespace()
   

3. By newlines:

    s.lines()
   

4. By regex: (using regex crate)

    Regex::new(r"\s").unwrap().split("one two three")
   

The result of each kind is an iterator:

let text = "foo\r\nbar\n\nbaz\n";
let mut lines = text.lines();

assert_eq!(Some("foo"), lines.next());
assert_eq!(Some("bar"), lines.next());
assert_eq!(Some(""), lines.next());
assert_eq!(Some("baz"), lines.next());

assert_eq!(None, lines.next());

Reflection, basically, i.e.

myObject.GetType().GetProperty(property).SetValue(myObject, "Bob", null);

or there are libraries to help both in terms of convenience and performance; for example with FastMember:

var wrapped = ObjectAccessor.Create(obj); 
wrapped[property] = "Bob";

(which also has the advantage of not needing to know in advance whether it is a field vs a property)

Use case wise the following seem to be easy to use and fast. Just set the page number.

use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6;
with result as(
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
)
select SalesOrderDetailID, SalesOrderID, ProductID from result
WHERE result.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)

also without CTE

use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6
SELECT SalesOrderDetailID, SalesOrderID, ProductID
FROM (
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
 ) AS SOD
WHERE SOD.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)

Take a look at the System.Net.WebClient class, it can be used to issue requests and handle their responses, as well as to download files:

After lot of failed tried attempts ,I found the solution

It was the ";" at end of JAVA_HOME which I always put at end of each new variable I set. So get rid of the ;.

JAVA_HOME set it in User Variable also (without the ";" ofcourse)

I use join to separate the word in array with "and, or , / , &"

EXAMPLE

HTML

<p>London Mexico Canada</p>
<div></div>

JS

 newText = $("p").text().split(" ").join(" or ");
 $('div').text(newText);

Results

London or Mexico or Canada

You state in the comments that the returned JSON is this:

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

You're telling Gson that you have an array of Post objects:

List<Post> postsList = Arrays.asList(gson.fromJson(reader,
                    Post[].class));

You don't. The JSON represents exactly one Post object, and Gson is telling you that.

Change your code to be:

Post post = gson.fromJson(reader, Post.class);

After making the id unique across the document ,You have to use event delegation

$("#container").on("click", "buttonid", function () {
  alert("Hi");
});

For regex, I first look at this web site: RegExLib.com

As we were already using jQuery for a graphical eye-candy feature we ended up using this. A code like

$(document).ready(function() {
    // any code goes here
    init();
});

did everything we wanted and cares about browser incompatibilities at its own.

At least on the current maven version you need to add the switch -DreResolve=false if you intend to remove the dependencies from your local repo without re-downloading them.

mvn dependency:purge-local-repository -DreResolve=false

removes the dependencies without downloading them again.

I ran into this issue when I had cloned a repo on my NAS and then cloned that repo on to my machines.

The set up is something like this:

ORIGINAL (github):

• cloned to network storage in my private home network (my home network)
  • branch checked out: DEVELOPMENT
• cloned to other machines (laptops, small data center server in my office, etc)
  • branch checked out: DEVELOPMENT

When I tried to commit to the from the laptop to the NAS server the error which comes up is

! [remote rejected]   development -> development (branch is currently checked out)

The root cause is that DEVELOPMENT branch is checked out on the NAS server. My solution was on the NAS repository to switch to any other branch. This let me commit my changes.

I guess this should work. I solved my problem with this.

You can use generic serial Comparator to sort collections by multiple fields.

import org.apache.commons.lang3.reflect.FieldUtils;
import java.util.Arrays;
import java.util.Comparator;
import java.util.List;

/**
* @author MaheshRPM
*/
public class SerialComparator<T> implements Comparator<T> {
List<String> sortingFields;

public SerialComparator(List<String> sortingFields) {
    this.sortingFields = sortingFields;
}

public SerialComparator(String... sortingFields) {
    this.sortingFields = Arrays.asList(sortingFields);
}

@Override
public int compare(T o1, T o2) {
    int result = 0;
    try {
        for (String sortingField : sortingFields) {
            if (result == 0) {
                Object value1 = FieldUtils.readField(o1, sortingField, true);
                Object value2 = FieldUtils.readField(o2, sortingField, true);
                if (value1 instanceof Comparable && value2 instanceof Comparable) {
                    Comparable comparable1 = (Comparable) value1;
                    Comparable comparable2 = (Comparable) value2;
                    result = comparable1.compareTo(comparable2);
                } else {
                    throw new RuntimeException("Cannot compare non Comparable fields. " + value1.getClass()
                            .getName() + " must implement Comparable<" + value1.getClass().getName() + ">");
                }
            } else {
                break;
            }

    } catch (IllegalAccessException e) {
        throw new RuntimeException(e);

There is no show event in js - you need to bind your button either to the click event:

$('#id').on('click', function (e) {

     //your awesome code here

})

Mind that if your button is inside a form, you may prefer to bind the whole form to the submit event.

sed '5!d' file

awk 'NR==5' file

The font-min-size and font-max-size CSS properties were removed from the CSS Fonts Module Level 4 specification (and never implemented in browsers AFAIK). And the CSS Working Group replaced the CSS examples with font-size: clamp(...) which doesn't have the greatest browser support yet so we'll have to wait for browsers to support it. See example in https://developer.mozilla.org/en-US/docs/Web/CSS/clamp#Examples.

Pseudo code, something like:

CASE
  When CHARINDEX('lactulose', dbo.Table.Column) > 0 Then 'BP Medication'
ELSE ''
END AS 'Medication Type'

This does not care where the keyword is found in the list and avoids depending on formatting of spaces and commas.

For all you non-xml config folks:

ObjectMapper objMapper = new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL);
HttpMessageConverter msgConverter = new MappingJackson2HttpMessageConverter(objMapper);
restTemplate.setMessageConverters(Collections.singletonList(msgConverter));

toBe() versus toEqual(): toEqual() checks equivalence. toBe(), on the other hand, makes sure that they're the exact same object.

I would say use toBe() when comparing values, and toEqual() when comparing objects.

When comparing primitive types, toEqual() and toBe() will yield the same result. When comparing objects, toBe() is a stricter comparison, and if it is not the exact same object in memory this will return false. So unless you want to make sure it's the exact same object in memory, use toEqual() for comparing objects.

Check this link out for more info : http://evanhahn.com/how-do-i-jasmine/

Now when looking at the difference between toBe() and toEqual() when it comes to numbers, there shouldn't be any difference so long as your comparison is correct. 5 will always be equivalent to 5.

A nice place to play around with this to see different outcomes is here

Update

An easy way to look at toBe() and toEqual() is to understand what exactly they do in JavaScript. According to Jasmine API, found here:

toEqual() works for simple literals and variables, and should work for objects

toBe() compares with ===

Essentially what that is saying is toEqual() and toBe() are similar Javascripts === operator except toBe() is also checking to make sure it is the exact same object, in that for the example below objectOne === objectTwo //returns false as well. However, toEqual() will return true in that situation.

Now, you can at least understand why when given:

var objectOne = {
    propertyOne: str,
    propertyTwo: num    
}

var objectTwo = {
    propertyOne: str,
    propertyTwo: num    
}

expect(objectOne).toBe(objectTwo); //returns false

That is because, as stated in this answer to a different, but similar question, the === operator actually means that both operands reference the same object, or in case of value types, have the same value.

Make sure your default namespace in the web project properties is the same as the namespace in the Global.asax.cs. I had modified the default namespace to make it a subnamespace, changing it back fixed this issue for me.

Try this one,

1. Create rounded_edittext.xml file in your Drawable

   <?xml version="1.0" encoding="utf-8"?>
   <shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle" android:padding="15dp">
   
       <solid android:color="#FFFFFF" />
       <corners
           android:bottomRightRadius="0dp"
           android:bottomLeftRadius="0dp"
           android:topLeftRadius="0dp"
           android:topRightRadius="0dp" />
       <stroke android:width="1dip" android:color="#f06060" />
   </shape>
   

2. Apply background for your EditText in xml file

   <EditText
       android:id="@+id/edit_expiry_date"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:padding="10dip"
       android:background="@drawable/rounded_edittext"
       android:hint="@string/shop_name"
       android:inputType="text" />  
   

3. You will get output like this

Having named method in place of the anonymous function in audioNode.addEventListener 's callback should eliminate the subject warning:

    componentDidMount(prevProps, prevState, prevContext) {
    let [audioNode, songLen] = [this.refs.audio, List.length-1];

    audioNode.addEventListener('ended', () => {
        this._endedPlay(songLen, () => {
            this._currSong(this.state.songIndex);
            this._Play(audioNode);
        });
    });

    audioNode.addEventListener('timeupdate', this.callbackMethod );
}

callBackMethod = () => {
    let [remainTime, remainTimeMin, remainTimeSec, remainTimeInfo] = [];

    if(!isNaN(audioNode.duration)) {
        remainTime = audioNode.duration - audioNode.currentTime;
        remainTimeMin = parseInt(remainTime/60);  // ???
        remainTimeSec = parseInt(remainTime%60);  // ???

        if(remainTimeSec < 10) {
            remainTimeSec = '0'+remainTimeSec;
        }
        remainTimeInfo = remainTimeMin + ':' + remainTimeSec;
        this.setState({'time': remainTimeInfo});
    }
}

And yes, named method is needed anyways because removeEventListener won't work with anonymous callbacks, as mentioned above several times.

What about something like this.

<div id="movie_item">
    <div class="movie_item_poster">
        <img src="..." style="max-width: 100%; max-height: 100%;">
    </div>

     <div id="movie_item_content">
        <div class="movie_item_content_year">year</div>
        <div class="movie_item_content_title">title</div>
        <div class="movie_item_content_plot">plot</div>
    </div>

    <div class="movie_item_toolbar">
        Lorem Ipsum...
    </div>
</div>

You don't have to float both movie_item_poster AND movie_item_content. Just float one of them...

#movie_item {
    position: relative;
    margin-top: 10px;
    height: 175px;
}

.movie_item_poster {
    float: left;
    height: 150px;
    width: 100px;
}

.movie_item_content {
    position: relative;
}

.movie_item_content_title {
}

.movie_item_content_year {
    float: right;
}

.movie_item_content_plot {
}

.movie_item_toolbar {
    clear: both;
    vertical-align: bottom;
    width: 100%;
    height: 25px;
}

Here it is as a JSFiddle.

This example uses jquery-cookie

Check if the cookie exists and has not expired - if either of those fails, then show the popup and set the cookie (Semi pseudo code):

if($.cookie('popup') != 'seen'){
    $.cookie('popup', 'seen', { expires: 365, path: '/' }); // Set it to last a year, for example.
    $j("#popup").delay(2000).fadeIn();
    $j('#popup-close').click(function(e) // You are clicking the close button
        {
        $j('#popup').fadeOut(); // Now the pop up is hiden.
    });
    $j('#popup').click(function(e) 
        {
        $j('#popup').fadeOut(); 
    });
};

function readContent(callback) {
    fs.readFile("./Index.html", function (err, content) {
        if (err) return callback(err)
        callback(null, content)
    })
}

readContent(function (err, content) {
    console.log(content)
})

Here is the code

$str = substr($str, 1); 

echo $str;

Output:

this is a applepie :)

You can't get the file size of local files with javascript in a standard way using a web browser.

But if the file is accessible from a remote path, you might be able to send a HEAD request using Javascript, and read the Content-length header, depending on the webserver

The fixform trick is neat, but:

1. You may not have access to the code of what loads in the new window.

2. Even if you do, you are depending on the fact that it always loads, error free.

3. And you are depending on the fact that the user won't click another button before the other page gets a chance to load and run fixform.

I would suggest doing this instead:

OnClientClick="aspnetForm.target ='_blank';setTimeout('fixform()', 500);"

And set up fixform on the same page, looking like this:

function fixform() {
   document.getElementById("aspnetForm").target = '';
}

As the others have said, you'll have to kill all processes that are listening on that port. The easiest way to do that would be to use the fuser(1) command. For example, to see all of the processes listening for http requests on port 80 (run as root or use sudo):

# fuser 80/tcp

If you want to kill them, then just add the -k option.

Another approach of doing this, albeit by using a heavier but powerful library - NLTK.

import nltk

fdist = nltk.FreqDist(a)
fdist.values()
fdist.most_common()

Pure Python2 w/o dep:

def relpath(cwd, path):
    """Create a relative path for path from cwd, if possible"""
    if sys.platform == "win32":
        cwd = cwd.lower()
        path = path.lower()
    _cwd = os.path.abspath(cwd).split(os.path.sep)
    _path = os.path.abspath(path).split(os.path.sep)
    eq_until_pos = None
    for i in xrange(min(len(_cwd), len(_path))):
        if _cwd[i] == _path[i]:
            eq_until_pos = i
        else:
            break
    if eq_until_pos is None:
        return path
    newpath = [".." for i in xrange(len(_cwd[eq_until_pos+1:]))]
    newpath.extend(_path[eq_until_pos+1:])
    return os.path.join(*newpath) if newpath else "."

You don't necessarily have to choose between the two paradigms. You can write software with an OO architecture using many functional concepts. FP and OOP are orthogonal in nature.

Take for example C#. You could say it's mostly OOP, but there are many FP concepts and constructs. If you consider Linq, the most important constructs that permit Linq to exist are functional in nature: lambda expressions.

Another example, F#. You could say it's mostly FP, but there are many OOP concepts and constructs available. You can define classes, abstract classes, interfaces, deal with inheritance. You can even use mutability when it makes your code clearer or when it dramatically increases performance.

Many modern languages are multi-paradigm.

Recommended readings

As I'm in the same boat (OOP background, learning FP), I'd suggest you some readings I've really appreciated:

• Functional Programming for Everyday .NET Development, by Jeremy Miller. A great article (although poorly formatted) showing many techniques and practical, real-world examples of FP on C#.

• Real-World Functional Programming, by Tomas Petricek. A great book that deals mainly with FP concepts, trying to explain what they are, when they should be used. There are many examples in both F# and C#. Also, Petricek's blog is a great source of information.

The way you are using await/async is poor at best, and it makes it hard to follow. You are mixing await with Task'1.Result, which is just confusing. However, it looks like you are looking at a final task result, rather than the contents.

I've rewritten your function and function call, which should fix your issue:

async Task<string> GetResponseString(string text)
{
    var httpClient = new HttpClient();

    var parameters = new Dictionary<string, string>();
    parameters["text"] = text;

    var response = await httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters));
    var contents = await response.Content.ReadAsStringAsync();

    return contents;
}

And your final function call:

Task<string> result = GetResponseString(text);
var finalResult = result.Result;

Or even better:

var finalResult = await GetResponseString(text);

Here's an extension method for removing adjacent duplicates in-situ. Call Sort() first and pass in the same IComparer. This should be more efficient than Lasse V. Karlsen's version which calls RemoveAt repeatedly (resulting in multiple block memory moves).

public static void RemoveAdjacentDuplicates<T>(this List<T> List, IComparer<T> Comparer)
{
    int NumUnique = 0;
    for (int i = 0; i < List.Count; i++)
        if ((i == 0) || (Comparer.Compare(List[NumUnique - 1], List[i]) != 0))
            List[NumUnique++] = List[i];
    List.RemoveRange(NumUnique, List.Count - NumUnique);
}

This way worked for me:

adding the path that you like:

export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add

checking: you can run 'export' cmd and check the output or you can check it using this cmd:

python -c "import sys; print(sys.path)"

The simplest way to modify all files of a project at once (batch) is through Line Endings Unify package:

1. Ctrl+Shift+P type inst + choose Install Package.
2. Type line end + choose Line Endings Unify.
3. Once installed, Ctrl+Shift+P + type end + choose Line Endings Unify.

4. OR (instead of 3.) copy:

   {
    "keys": ["ctrl+alt+l"],
    "command": "line_endings_unify"
   },
   

   to the User array (right pane, after the opening [) in Preferences -> KeyBindings + press Ctrl+Alt+L.

As mentioned in another answer:

• The Carriage Return (CR) character (0x0D, \r) [...] Early Macintosh operating systems (OS-9 and earlier).

• The Line Feed (LF) character (0x0A, \n) [...] UNIX based systems (Linux, Mac OSX)

• The End of Line (EOL) sequence (0x0D 0x0A, \r\n) [...] (non-Unix: Windows, Symbian OS).

If you have node_modules, build or other auto-generated folders, delete them before running the package.

When you run the package:

1. you are asked at the bottom to choose which file extensions to search through a comma separated list (type the only ones you need to speed up the replacements, e.g. js,jsx).
2. then you are asked which Input line ending to use, e.g. if you need LF type \n.
3. press ENTER and wait until you see an alert window with LineEndingsUnify Complete.

You could do this:

Map<String, List<Student>> map = new HashMap<String, List<Student>>();
List<Student> studlist = new ArrayList<Student>();
studlist.add(new Student("1726", "John", "New York"));
map.put("New York", studlist);

the keys will be locations and the values list of students. So later you can get a group of students just by using:

studlist = map.get("New York");

How about:

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

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

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

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

Without actually seeing your data it is difficult to say how to find location of max and min in your particular case, but in general, you can search for the locations as follows. This is just a simple example below:

In [9]: a=np.array([5,1,2,3,10,4])

In [10]: np.where(a == a.min())
Out[10]: (array([1]),)

In [11]: np.where(a == a.max())
Out[11]: (array([4]),)

Alternatively, you can also do as follows:

In [19]: a=np.array([5,1,2,3,10,4])

In [20]: a.argmin()
Out[20]: 1

In [21]: a.argmax()
Out[21]: 4

This should do the trick...

'recalculate all open workbooks
Application.Calculate

'recalculate a specific worksheet
Worksheets(1).Calculate

' recalculate a specific range
Worksheets(1).Columns(1).Calculate

I just found the "-fae" parameter, which causes Maven to run all tests and not stop on failure.

You have to add the selector parameter, otherwise the event is directly bound instead of delegated, which only works if the element already exists (so it doesn't work for dynamically loaded content).

See http://api.jquery.com/on/#direct-and-delegated-events

Change your code to

$(document.body).on('click', '.update' ,function(){

The jQuery set receives the event then delegates it to elements matching the selector given as argument. This means that contrary to when using live, the jQuery set elements must exist when you execute the code.

As this answers receives a lot of attention, here are two supplementary advises :

1) When it's possible, try to bind the event listener to the most precise element, to avoid useless event handling.

That is, if you're adding an element of class b to an existing element of id a, then don't use

$(document.body).on('click', '#a .b', function(){

but use

$('#a').on('click', '.b', function(){

2) Be careful, when you add an element with an id, to ensure you're not adding it twice. Not only is it "illegal" in HTML to have two elements with the same id but it breaks a lot of things. For example a selector "#c" would retrieve only one element with this id.

You don't need regex for this. Just a character-by-character replace is sufficient. You can use String#replace() for this.

String replaced = original.replace("\"", " ");

Note that you can also use an empty string "" instead to replace with. Else the spaces would double up.

String replaced = original.replace("\"", "");

It's an attribute designed to help assistive technology (e.g. screen readers) attach a label to an otherwise anonymous HTML element.

So there's the <label> element:

<label for="fmUserName">Your name</label>
<input id="fmUserName">

The <label> explicitly tells the user to type their name into the input box where id="fmUserName".

aria-label does much the same thing, but it's for those cases where it isn't practical or desirable to have a label on screen. Take the MDN example:

<button aria-label="Close" onclick="myDialog.close()">X</button>`

Most people would be able to infer visually that this button will close the dialog. A blind person using assistive technology might just hear "X" read aloud, which doesn't mean much without the visual clues. aria-label explicitly tells them what the button will do.

To get the full file path of a selected file or files, then you need to use FileName property for one file or FileNames property for multiple files.

var file = choofdlog.FileName; // for one file

or for multiple files

var files = choofdlog.FileNames; // for multiple files.

To get the directory of the file, you can use Path.GetDirectoryName
Here is Jon Keet's answer to a similar question about getting directories from path

Use a framework like JQuery to do things like:

function toggleStatus() {
    if ($('#toggleElement').is(':checked')) {
        $('#idOfTheDIV :input').attr('disabled', true);
    } else {
        $('#idOfTheDIV :input').removeAttr('disabled');
    }   
}

Disable And Enable Input Elements In A Div Block Using jQuery should help you!

As of jQuery 1.6, you should use .prop instead of .attr for disabling.

You can also use AppCompatSpinner widget:

<android.support.v7.widget.AppCompatSpinner
    android:id="@+id/spinner_order_type"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:backgroundTint="@color/red"/>

Inside your Activity class:

AppCompatSpinner spinOrderType = (AppCompatSpinner) findViewById(R.id.spinner_order_type);
List<String> categories = new ArrayList<String>();
        categories.add(getString(R.string.label_table_order));
        categories.add(getString(R.string.label_take_away));

        ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(mContext,
                R.layout.layout_spinner_item, categories);
        dataAdapter.setDropDownViewResource(R.layout.layout_spinner_item);
        spinOrderType.setAdapter(dataAdapter);
        spinOrderType.setSelection(0);

        spinOrderType.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long l) {
                String item = parent.getItemAtPosition(position).toString();
                Log.d(TAG, item);
            }

            @Override
            public void onNothingSelected(AdapterView<?> adapterView) {

            }
        });

layout_spinner_item.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:tools="http://schemas.android.com/tools"
    android:gravity="left"
    android:textSize="@dimen/text.size.large"
    android:textColor="@color/text.link"
    android:padding="@dimen/margin.3" />

STEP 1: FIRST OPEN THE COMMAND PROMPT WHERE YOUR FILE IS LOCATED. (right click while pressing shift)
STEP 2: THEN USE THE FOLLOWING COMMANDS TO EXECUTE. (lets say the file and class name to be executed is named as Student.java)The example program is in the picture background.

     javac Student.java
     java Student

In SQL server you would use TOP together with ROW_NUMBER()

• suppose you have an array like

   const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9]
    
    
    arr.map((myArr, index) => {
      console.log(`your index is -> ${index} AND value is ${myArr}`);
    })

> output will be
 index is -> 0 AND value is 1
 index is -> 1 AND value is 2
 index is -> 2 AND value is 3
 index is -> 3 AND value is 4
 index is -> 4 AND value is 5
 index is -> 5 AND value is 6
 index is -> 6 AND value is 7
 index is -> 7 AND value is 8
 index is -> 8 AND value is 9

Using @extend is a fine solution, but be aware that the compiled css will break up the class definition. Any classes that extends the same placeholder will be grouped together and the rules that aren't extended in the class will be in a separate definition. If several classes become extended, it can become unruly to look up a selector in the compiled css or the dev tools. Whereas a mixin will duplicate the mixin code and add any additional styles.

You can see the difference between @extend and @mixin in this sassmeister

You can use concat:

In [11]: pd.concat([df1['c'], df2['c']], axis=1, keys=['df1', 'df2'])
Out[11]: 
                 df1       df2
2014-01-01       NaN -0.978535

2014-01-03 -0.846100 -0.313153
2014-01-04 -0.014253 -1.040702
2014-01-05  0.315156 -0.329967

2014-01-07       NaN -0.024608
2014-01-08       NaN -1.791899

[8 rows x 2 columns]

The axis argument determines the way the DataFrames are stacked:

df1 = pd.DataFrame([1, 2, 3])
df2 = pd.DataFrame(['a', 'b', 'c'])

pd.concat([df1, df2], axis=0)
   0
0  1
1  2
2  3
0  a
1  b
2  c

pd.concat([df1, df2], axis=1)

   0  0
0  1  a

2  3  c

getClass().getResource() uses the class loader to load the resource. This means that the resource must be in the classpath to be loaded.

When doing it with Eclipse, everything you put in the source folder is "compiled" by Eclipse:

• .java files are compiled into .class files that go the the bin directory (by default)
• other files are copied to the bin directory (respecting the package/folder hirearchy)

When launching the program with Eclipse, the bin directory is thus in the classpath, and since it contains the Test.properties file, this file can be loaded by the class loader, using getResource() or getResourceAsStream().

If it doesn't work from the command line, it's thus because the file is not in the classpath.

Note that you should NOT do

FileInputStream inputStream = new FileInputStream(new File(getClass().getResource(url).toURI()));

to load a resource. Because that can work only if the file is loaded from the file system. If you package your app into a jar file, or if you load the classes over a network, it won't work. To get an InputStream, just use

getClass().getResourceAsStream("Test.properties")

And finally, as the documentation indicates,

Foo.class.getResourceAsStream("Test.properties")

will load a Test.properties file located in the same package as the class Foo.

Foo.class.getResourceAsStream("/com/foo/bar/Test.properties")

will load a Test.properties file located in the package com.foo.bar.

I have just thought of a great solution to this that works with both source and header files, is very efficient and works on compile time in all platforms without compiler-specific extensions. This solution also preserves the relative directory structure of your project, so you know in which folder the file is in, and only relative to the root of your project.

The idea is to get the size of the source directory with your build tool and just add it to the __FILE__ macro, removing the directory entirely and only showing the file name starting at your source directory.

The following example is implemented using CMake, but there's no reason it wouldn't work with any other build tools, because the trick is very simple.

On the CMakeLists.txt file, define a macro that has the length of the path to your project on CMake:

# The additional / is important to remove the last character from the path.
# Note that it does not matter if the OS uses / or \, because we are only
# saving the path size.
string(LENGTH "${CMAKE_SOURCE_DIR}/" SOURCE_PATH_SIZE)
add_definitions("-DSOURCE_PATH_SIZE=${SOURCE_PATH_SIZE}")

On your source code, define a __FILENAME__ macro that just adds the source path size to the __FILE__ macro:

#define __FILENAME__ (__FILE__ + SOURCE_PATH_SIZE)

Then just use this new macro instead of the __FILE__ macro. This works because the __FILE__ path will always start with the path to your CMake source dir. By removing it from the __FILE__ string the preprocessor will take care of specifying the correct file name and it will all be relative to the root of your CMake project.

If you care about the performance, this is as efficient as using __FILE__, because both __FILE__ and SOURCE_PATH_SIZE are known compile time constants, so it can be optimized away by the compiler.

The only place where this would fail is if you're using this on generated files and they're on a off-source build folder. Then you'll probably have to create another macro using the CMAKE_BUILD_DIR variable instead of CMAKE_SOURCE_DIR.

Try Demo Here

var list ={}; var count= Object.keys(list).length;

This is a C++ interview test question not homework.

Then your interviewer needs to refresh his recollection with how the C++ standard works. And I quote:

For an enumeration whose underlying type is not fixed, the underlying type is an integral type that can represent all the enumerator values defined in the enumeration.

The whole "whose underlying type is not fixed" part is from C++11, but the rest is all standard C++98/03. In short, the sizeof(months_t) is not 4. It is not 2 either. It could be any of those. The standard does not say what size it should be; only that it should be big enough to fit any enumerator.

why the all size is 4 bytes ? not 12 x 4 = 48 bytes ?

Because enums are not variables. The members of an enum are not actual variables; they're just a semi-type-safe form of #define. They're a way of storing a number in a reader-friendly format. The compiler will transform all uses of an enumerator into the actual numerical value.

Enumerators are just another way of talking about a number. january is just shorthand for 0. And how much space does 0 take up? It depends on what you store it in.

To remove all doted outline, including those in bootstrap themes.

a, a:active, a:focus, 
button, button:focus, button:active, 
.btn, .btn:focus, .btn:active:focus, .btn.active:focus, .btn.focus, .btn.focus:active, .btn.active.focus {
    outline: none;
    outline: 0;
}

input::-moz-focus-inner {
    border: 0;
}

Note: You should add link href for bootstrap css before the main css, so bootstrap doesn't override your style.

Call c_str() to get a const char * (LPCSTR) from a std::string.

It's all in the name:

LPSTR - (long) pointer to string - char *

LPCSTR - (long) pointer to constant string - const char *

LPWSTR - (long) pointer to Unicode (wide) string - wchar_t *

LPCWSTR - (long) pointer to constant Unicode (wide) string - const wchar_t *

LPTSTR - (long) pointer to TCHAR (Unicode if UNICODE is defined, ANSI if not) string - TCHAR *

LPCTSTR - (long) pointer to constant TCHAR string - const TCHAR *

You can ignore the L (long) part of the names -- it's a holdover from 16-bit Windows.

The number of string occurrences (not lines) can be obtained using grep with -o option and wc (word count):

$ echo "echo 1234 echo" | grep -o echo
echo
echo
$ echo "echo 1234 echo" | grep -o echo | wc -l
2

So the full solution for your problem would look like this:

$ grep -o "echo" FILE | wc -l

var id_tag = [1,2,3,78,5,6,7,8,47,34,90]; 
var delete_where_id_tag = 90
    id_tag =id_tag.filter((x)=> x!=delete_where_id_tag); 

You could use if(number >= 0). The fact that you use int number = input.nextInt(); makes sure that it has to be an Integer.

Here are some differences:

1. You can call app.render on root level and res.render only inside a route/middleware.

2. app.render always returns the html in the callback function, whereas res.render does so only when you've specified the callback function as your third parameter. If you call res.render without the third parameter/callback function the rendered html is sent to the client with a status code of 200.

   Take a look at the following examples.

   • app.render

     app.render('index', {title: 'res vs app render'}, function(err, html) {
         console.log(html)
     });
     
     // logs the following string (from default index.jade)
     <!DOCTYPE html><html><head><title>res vs app render</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body><h1>res vs app render</h1><p>Welcome to res vs app render</p></body></html>
     

   • res.render without third parameter

     app.get('/render', function(req, res) {
         res.render('index', {title: 'res vs app render'})
     })
     
     // also renders index.jade but sends it to the client 
     // with status 200 and content-type text/html on GET /render
     

   • res.render with third parameter

     app.get('/render', function(req, res) {
         res.render('index', {title: 'res vs app render'}, function(err, html) {
             console.log(html);
             res.send('done');
         })
     })
     
     // logs the same as app.render and sends "done" to the client instead 
     // of the content of index.jade
     

3. res.render uses app.render internally to render template files.

4. You can use the render functions to create html emails. Depending on your structure of your app, you might not always have acces to the app object.

   For example inside an external route:

   app.js

I had a hard-coded IP in httpd.conf and my local IP had changed which was causing my issue, changed IP over and all worked again

After adding the cordova-plugin-whitelist, you must tell your application to allow access all the web-page links or specific links, if you want to keep it specific.

You can simply add this to your config.xml, which can be found in your application's root directory:

Recommended in the documentation:

<allow-navigation href="http://example.com/*" />

or:

<allow-navigation href="http://*/*" />

From the plugin's documentation:

Navigation Whitelist

Controls which URLs the WebView itself can be navigated to. Applies to top-level navigations only.

Quirks: on Android it also applies to iframes for non-http(s) schemes.

By default, navigations only to file:// URLs, are allowed. To allow other other URLs, you must add tags to your config.xml:

<!-- Allow links to example.com -->
<allow-navigation href="http://example.com/*" />

<!-- Wildcards are allowed for the protocol, as a prefix
     to the host, or as a suffix to the path -->
<allow-navigation href="*://*.example.com/*" />

<!-- A wildcard can be used to whitelist the entire network,
     over HTTP and HTTPS.
     *NOT RECOMMENDED* -->
<allow-navigation href="*" />

<!-- The above is equivalent to these three declarations -->
<allow-navigation href="http://*/*" />
<allow-navigation href="https://*/*" />
<allow-navigation href="data:*" />

With selectable date ranges you might want to use something like this. My solution prevents selecting #from_date bigger than #to_date and changes #to_date startDate every time when user selects new date in #from_date box:

http://bootply.com/74352

JS file:

var startDate = new Date('01/01/2012');
var FromEndDate = new Date();
var ToEndDate = new Date();

ToEndDate.setDate(ToEndDate.getDate()+365);

$('.from_date').datepicker({

    weekStart: 1,
    startDate: '01/01/2012',
    endDate: FromEndDate, 
    autoclose: true
})
    .on('changeDate', function(selected){
        startDate = new Date(selected.date.valueOf());
        startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
        $('.to_date').datepicker('setStartDate', startDate);
    }); 
$('.to_date')
    .datepicker({

        weekStart: 1,
        startDate: startDate,
        endDate: ToEndDate,
        autoclose: true
    })
    .on('changeDate', function(selected){
        FromEndDate = new Date(selected.date.valueOf());
        FromEndDate.setDate(FromEndDate.getDate(new Date(selected.date.valueOf())));
        $('.from_date').datepicker('setEndDate', FromEndDate);
    });

HTML:

<input class="from_date" placeholder="Select start date" contenteditable="false" type="text">
<input class="to_date" placeholder="Select end date" contenteditable="false" type="text" 

And do not forget to include bootstrap datepicker.js and .css files aswell.

Read MSDN.

it also contains a link to the args.

short answer: no, the main does not get override. when visual studio (actually the compiler) builds your exe it must declare a starting point for the assmebly, that point is the main function.

if you meant how to literary pass args then you can either run you're app from the command line with them (e.g. appname.exe param1 param2) or in the project setup, enter them (in the command line arguments in the Debug tab)

in the main you will need to read those args for example:

for (int i = 0; i < args.Length; i++)
{
    string flag = args.GetValue(i).ToString();
    if (flag == "bla") 
    {
        Bla();
    }
}

Or use group_by & summarise_at from the dplyr package:

library(dplyr)

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

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

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

I have faced this type of error. to call a function from the razor.

public ActionResult EditorAjax(int id, int? jobId, string type = ""){}

solved that by changing the line

from

<a href="/ScreeningQuestion/EditorAjax/5&jobId=2&type=additional" /> 

to

<a href="/ScreeningQuestion/EditorAjax/?id=5&jobId=2&type=additional" />

where my route.config is

routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }, new string[] { "RPMS.Controllers" } // Parameter defaults
        );

I consider this simpler than any prior correct answer. I'll also throw in javadoc. :-)

/**
 * Converts the given string to title case, where the first
 * letter is capitalized and the rest of the string is in
 * lower case.
 * 
 * @param s a string with unknown capitalization
 * @return a title-case version of the string
 */
public static String toTitleCase(String s)
{
    if (s.isEmpty())
    {
        return s;
    }
    return s.substring(0, 1).toUpperCase() + s.substring(1).toLowerCase();
}

Strings of length 1 do not needed to be treated as a special case because s.substring(1) returns the empty string when s has length 1.

The solution was as simple as adding plt.show() at the end of the code snippet:

import numpy as np
np.random.seed(123)
from keras.models import Sequential
from keras.layers import Dense, Dropout, Activation, Flatten
from keras.layers import Convolution2D, MaxPooling2D
from keras.utils import np_utils
from keras.datasets import mnist
(X_train,y_train),(X_test,y_test) = mnist.load_data()
print X_train.shape
from matplotlib import pyplot as plt
plt.imshow(X_train[0])
plt.show()

Having: It applies filter conditions to each group of rows. Where: It applies a filter of individual rows.

Give name and values to those submit buttons like:

    <td>
    <input type="submit" name='mybutton' class="noborder" id="save" value="save" alt="Save" tabindex="4" />
    </td>
    <td>
    <input type="submit" name='mybutton' class="noborder" id="publish" value="publish" alt="Publish" tabindex="5" />
    </td>

and then in your php script you could check

if($_POST['mybutton'] == 'save')
{
  ///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
  ///do publish processing here
}

If the code should be simple, then you probably asking for C example based on traditional BSD sockets. Solutions like boost::asio are imho quite complicated when it comes to short and simple "hello world" example.

To compile examples you mentioned you must make simple fixes, because you are compiling under C++ compiler. I'm referring to following files:
http://www.linuxhowtos.org/data/6/server.c
http://www.linuxhowtos.org/data/6/client.c
from: http://www.linuxhowtos.org/C_C++/socket.htm

1. Add following includes to both files:

   #include <cstdlib>
   #include <cstring>
   #include <unistd.h>
   

2. In client.c, change the line:

   if (connect(sockfd,&serv_addr,sizeof(serv_addr)) < 0)
   { ... }
   

   to:

   if (connect(sockfd,(const sockaddr*)&serv_addr,sizeof(serv_addr)) < 0)
   { ... }
   

As you can see in C++ an explicit cast is needed.

This is because you have made conflicting changes to its master. And your repository server is not able to tell you that with these words, so it gives this error because it is not a matter of him deal with these conflicts for you, so he asks you to do it by itself. As ?

1- git pull This will merge your code from your repository to your code of your site master. So conflicts are shown.

2- treat these manualemente conflicts.

3-

git push origin master

And presto, your problem has been resolved.

1. Install ILMerge as the other threads tell you to

2. Then go to the installation folder, by default C:\Program Files (x86)\Microsoft\ILMerge

3. Drag your Dll's and Exes to that folder

4. Shift-Rightclick in that folder and choose open command prompt

5. Write

   ilmerge myExe.exe Dll1.dll /out:merged.exe
   

   Note that you should write your exe first.

There you got your merged exe. This might not be the best way if your going to do this multiple times, but the simplest one for a one time use, I would recommend putting Ilmerge to your path.

I guess I came a little late for this but I think the main problem here is that you're patching datetime.date.today directly and, according to the documentation, this is wrong.

You should patch the reference imported in the file where the tested function is, for example.

Let's say you have a functions.py file where you have the following:

import datetime

def get_today():
    return datetime.date.today()

then, in your test, you should have something like this

import datetime
import unittest

from functions import get_today
from mock import patch, Mock

class GetTodayTest(unittest.TestCase):

    @patch('functions.datetime')
    def test_get_today(self, datetime_mock):
        datetime_mock.date.today = Mock(return_value=datetime.strptime('Jun 1 2005', '%b %d %Y'))
        value = get_today()
        # then assert your thing...

Hope this helps a little bit.

Alternatively, in python 3.6+, you can generate Unicode superscript and copy paste that in your code:

ax1.set_ylabel('Rate (min?¹)')

A better pyramid can be printed this way:

The Pattern is
     $     
    $$$    
   $$$$$   
  $$$$$$$  
 $$$$$$$$$ 
$$$$$$$$$$$

public static void main(String agrs[]) {
    System.out.println("The Pattern is");
    int size = 11; //use only odd numbers here
    for (int i = 1; i <= size; i=i+2) {
        int spaceCount = (size - i)/2;
        for(int j = 0; j< size; j++) {
            if(j < spaceCount || j >= (size - spaceCount)) {
                System.out.print(" ");
            } else {
                System.out.print("$");
            }
        }
        System.out.println();
    }
}

I think clang could be an alternative.

GCC and clang have some differences on expressions like a+++++a, and I've got many different answers with my peer who use clang on Mac while I use gcc.

GCC has become the standard, and clang could be an alternative. Because GCC is very stable and clang is still under developing.

After trying all other suggested solutions and don't getting my project to work, I finally found a little comment in this page:

Deleting the BIN-Folder did it for me

And it worked for me too.

This feature is known as generics. http://msdn.microsoft.com/en-us/library/512aeb7t(v=vs.100).aspx

An example of this is to make a collection of items of a specific type.

class MyArray<T>
{
    T[] array = new T[10];

    public T GetItem(int index)
    {
        return array[index];
    }
}

In your code, you could then do something like this:

MyArray<int> = new MyArray<int>();

In this case, T[] array would work like int[] array, and public T GetItem would work like public int GetItem.

I found that, when you use EXTERNAL TABLE and LOCATION together, Hive creates table and initially no data will present (assuming your data location is different from the Hive 'LOCATION').

When you use 'LOAD DATA INPATH' command, the data get MOVED (instead of copy) from data location to location that you specified while creating Hive table.

If location is not given when you create Hive table, it uses internal Hive warehouse location and data will get moved from your source data location to internal Hive data warehouse location (i.e. /user/hive/warehouse/).

I follow Jason's step, but not works.

And then I find the WTP Update site http://download.eclipse.org/webtools/updates/.

Help -> Install new software -> Add > WTP:http://download.eclipse.org/webtools/updates/ -> OK

Then Help -> Check for update, just works, I don't know whether Jason's affect this .

Was trying to do this with an access database and found I needed to use a.* right after the delete.

DELETE a.*

You could always write a simple program in Python or something to create an include file that has simple #define statements with a build number, time, and date. You would then need to run this program before doing a build.

If you like I'll write one and post source here.

If you are lucky, your build tool (IDE or whatever) might have the ability to run an external command, and then you could have the external tool rewrite the include file automatically with each build.

EDIT: Here's a Python program. This writes a file called build_num.h and has an integer build number that starts at 1 and increments each time this program is run; it also writes #define values for the year, month, date, hours, minutes and seconds of the time this program is run. It also has a #define for major and minor parts of the version number, plus the full VERSION and COMPLETE_VERSION that you wanted. (I wasn't sure what you wanted for the date and time numbers, so I went for just concatenated digits from the date and time. You can change this easily.)

Each time you run it, it reads in the build_num.h file, and parses it for the build number; if the build_num.h file does not exist, it starts the build number at 1. Likewise it parses out major and minor version numbers, and if the file does not exist defaults those to version 0.1.

import time

FNAME = "build_num.h"

build_num = None
version_major = None
version_minor = None

DEF_BUILD_NUM = "#define BUILD_NUM "
DEF_VERSION_MAJOR = "#define VERSION_MAJOR "
DEF_VERSION_MINOR = "#define VERSION_MINOR "

def get_int(s_marker, line):
    _, _, s = line.partition(s_marker) # we want the part after the marker
    return int(s)

try:
    with open(FNAME) as f:
        for line in f:
            if DEF_BUILD_NUM in line:
                build_num = get_int(DEF_BUILD_NUM, line)
                build_num += 1
            elif DEF_VERSION_MAJOR in line:
                version_major = get_int(DEF_VERSION_MAJOR, line)
            elif DEF_VERSION_MINOR in line:
                version_minor = get_int(DEF_VERSION_MINOR, line)
except IOError:
    build_num = 1
    version_major = 0
    version_minor = 1

assert None not in (build_num, version_major, version_minor)


with open(FNAME, 'w') as f:
    f.write("#ifndef BUILD_NUM_H\n")
    f.write("#define BUILD_NUM_H\n")
    f.write("\n")
    f.write(DEF_BUILD_NUM + "%d\n" % build_num)
    f.write("\n")
    t = time.localtime()
    f.write("#define BUILD_YEAR %d\n" % t.tm_year)
    f.write("#define BUILD_MONTH %d\n" % t.tm_mon)
    f.write("#define BUILD_DATE %d\n" % t.tm_mday)
    f.write("#define BUILD_HOUR %d\n" % t.tm_hour)
    f.write("#define BUILD_MIN %d\n" % t.tm_min)
    f.write("#define BUILD_SEC %d\n" % t.tm_sec)
    f.write("\n")
    f.write("#define VERSION_MAJOR %d\n" % version_major)
    f.write("#define VERSION_MINOR %d\n" % version_minor)
    f.write("\n")
    f.write("#define VERSION \"%d.%d\"\n" % (version_major, version_minor))
    s = "%d.%d.%04d%02d%02d.%02d%02d%02d" % (version_major, version_minor,
            t.tm_year, t.tm_mon, t.tm_mday, t.tm_hour, t.tm_min, t.tm_sec)
    f.write("#define COMPLETE_VERSION \"%s\"\n" % s)
    f.write("\n")
    f.write("#endif // BUILD_NUM_H\n")

I made all the defines just be integers, but since they are simple integers you can use the standard stringizing tricks to build a string out of them if you like. Also you can trivially extend it to build additional pre-defined strings.

This program should run fine under Python 2.6 or later, including any Python 3.x version. You could run it under an old Python with a few changes, like not using .partition() to parse the string.

This link explains where you're going wrong:

[35.12] Why can't I separate the definition of my templates class from its declaration and put it inside a .cpp file?

Place the definition of your constructors, destructors methods and whatnot in your header file, and that will correct the problem.

This offers another solution:

How can I avoid linker errors with my template functions?

However this requires you to anticipate how your template will be used and, as a general solution, is counter-intuitive. It does solve the corner case though where you develop a template to be used by some internal mechanism, and you want to police the manner in which it is used.

You can add JavaScript code in an HTML document by employing the dedicated HTML tag <script> that wraps around JavaScript code.

The <script> tag can be placed in the <head> section of your HTML, in the <body> section, or after the </body> close tag, depending on when you want the JavaScript to load.

Generally, JavaScript code can go inside of the document <head> section in order to keep them contained and out of the main content of your HTML document.

However, if your script needs to run at a certain point within a page’s layout — like when using document.write to generate content — you should put it at the point where it should be called, usually within the <body> section.

geonames is nice. an export tool based on geonames:

https://github.com/yosoyadri/GeoNames-XML-Builder

there's also the excellent pycountry module:

Based on the accepted but now deleted answer provided by ageektrapped I created a slimmed down version without some of the more advanced features. All the code is included here to allow you to copy-paste it and not get blocked by link-rot.

I use the System.ComponentModel.DescriptionAttribute which really is intended for design time descriptions. If you dislike using this attribute you may create your own but I think using this attribute really gets the job done. If you don't use the attribute the name will default to the name of the enum value in code.

public enum ExampleEnum {

  [Description("Foo Bar")]
  FooBar,

  [Description("Bar Foo")]
  BarFoo

}

Here is the class used as the items source:

public class EnumItemsSource : Collection<String>, IValueConverter {

  Type type;

  IDictionary<Object, Object> valueToNameMap;

  IDictionary<Object, Object> nameToValueMap;

  public Type Type {
    get { return this.type; }
    set {
      if (!value.IsEnum)
        throw new ArgumentException("Type is not an enum.", "value");
      this.type = value;
      Initialize();
    }
  }

  public Object Convert(Object value, Type targetType, Object parameter, CultureInfo culture) {
    return this.valueToNameMap[value];
  }

  public Object ConvertBack(Object value, Type targetType, Object parameter, CultureInfo culture) {
    return this.nameToValueMap[value];
  }

  void Initialize() {
    this.valueToNameMap = this.type
      .GetFields(BindingFlags.Static | BindingFlags.Public)
      .ToDictionary(fi => fi.GetValue(null), GetDescription);
    this.nameToValueMap = this.valueToNameMap
      .ToDictionary(kvp => kvp.Value, kvp => kvp.Key);
    Clear();
    foreach (String name in this.nameToValueMap.Keys)
      Add(name);
  }

  static Object GetDescription(FieldInfo fieldInfo) {
    var descriptionAttribute =
      (DescriptionAttribute) Attribute.GetCustomAttribute(fieldInfo, typeof(DescriptionAttribute));
    return descriptionAttribute != null ? descriptionAttribute.Description : fieldInfo.Name;
  }

}

You can use it in XAML like this:

<Windows.Resources>
  <local:EnumItemsSource
    x:Key="ExampleEnumItemsSource"
    Type="{x:Type local:ExampleEnum}"/>
</Windows.Resources>
<ComboBox
  ItemsSource="{StaticResource ExampleEnumItemsSource}"
  SelectedValue="{Binding ExampleProperty, Converter={StaticResource ExampleEnumItemsSource}}"/> 

Can be achieved also with scriptrunner

ScriptRunner.exe -appvscript demoA.cmd arg1 arg2 -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror -appvscript demoB.ps1 arg3 arg4 -appvscriptrunnerparameters -wait -timeout=30 

Which also have some features as rollback , timeout and waiting.

Yes, there is a way to emulate max-width using a table, thus giving you both responsive and Outlook-friendly layout. What's more, this solution doesn't require conditional comments.

Suppose you want the equivalent of a centered div with max-width of 350px. You create a table, set the width to 100%. The table has three cells in a row. Set the width of the center TD to 350 (using the HTML width attribute, not CSS), and there you go.

If you want your content aligned left instead of centered, just leave out the first empty cell.

Example:

<table border="0" cellspacing="0" width="100%">
    <tr>
        <td></td>
        <td width="350">The width of this cell should be a maximum of 
                  350 pixels, but shrink to widths less than 350 pixels.
        </td>
        <td></td>
     </tr>
</table> 

In the jsfiddle I give the table a border so you can see what's going on, but obviously you wouldn't want one in real life:

http://jsfiddle.net/YcwM7/

Implementation wise you will often see inside super() statement in subclasses constructors, something like:

public class A extends AbstractB{

  public A(...){
     super(String constructorArgForB, ...);
     ...
  }
}

You have to add a manifest permission entry:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

(of course you should list all other permissions that your app uses).

Then, implement BroadcastReceiver class, it should be simple and fast executable. The best approach is to set an alarm in this receiver to wake up your service (if it's not necessary to keep it running ale the time as Prahast wrote).

public class BootUpReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, MyService.class), PendingIntent.FLAG_UPDATE_CURRENT);
        am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + interval, interval, pi);
    }
}

Then, add a Receiver class to your manifest file:

<receiver android:enabled="true" android:name=".receivers.BootUpReceiver"
    android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

Specifying the path to the DLL file in your project's settings does not ensure that your application will find the DLL at run-time. You only told Visual Studio how to find the files it needs. That has nothing to do with how the program finds what it needs, once built.

Placing the DLL file into the same folder as the executable is by far the simplest solution. That's the default search path for dependencies, so you won't need to do anything special if you go that route.
To avoid having to do this manually each time, you can create a Post-Build Event for your project that will automatically copy the DLL into the appropriate directory after a build completes.

Alternatively, you could deploy the DLL to the Windows side-by-side cache, and add a manifest to your application that specifies the location.

$('#slick-slider').slick('refresh'); //Working for slick 1.8.1

If you have a function like:

int foo()
{
    // more stuff
    foo();
}

Then foo() will keep calling itself, getting deeper and deeper, and when the space used to keep track of what functions you're in is filled up, you get the stack overflow error.

If I may add one more solution: you can simply cancel the clipboard with this command:

Application.CutCopyMode = False

validate last name is blank

SELECT  
person.fullName,
(CASE WHEN 0 = CHARINDEX(' ', person.fullName) 
    then  person.fullName 
    ELSE SUBSTRING(person.fullName, 1, CHARINDEX(' ', person.fullName)) end) as first_name,  
(CASE WHEN 0 = CHARINDEX(' ', person.fullName) 
    THEN ''  
    ELSE SUBSTRING(person.fullName,CHARINDEX(' ', person.fullName), LEN(person.fullName) )end) last_name

FROM person

if you want to select all on "On_Enter Event" this won't Help you achieving your goal. Try using "On_Click Event"

    private void textBox_Click(object sender, EventArgs e)
    {
        textBox.Focus();
        textBox.SelectAll();
    }

/([1-9][0-9]*)|0/

I found this by adapting some tutos. Thanks to google, and to all of you ;)

def findall(L, test):
    i=0
    indices = []
    while(True):
        try:
            # next value in list passing the test
            nextvalue = filter(test, L[i:])[0]

            # add index of this value in the index list,
            # by searching the value in L[i:] 
            indices.append(L.index(nextvalue, i))

            # iterate i, that is the next index from where to search
            i=indices[-1]+1
        #when there is no further "good value", filter returns [],
        # hence there is an out of range exeption
        except IndexError:
            return indices

A very simple use:

a = [0,0,2,1]
ind = findall(a, lambda x:x>0))

[2, 3]

P.S. scuse my english

I prefer to limit the number of retries, so that if there's a problem with that specific item you will eventually continue onto the next one, thus:

for i in range(100):
  for attempt in range(10):
    try:
      # do thing
    except:
      # perhaps reconnect, etc.
    else:
      break
  else:
    # we failed all the attempts - deal with the consequences.

I think you are making it too complex. AttributedString is used when you want to store attributes - in Printing Context. But You are storing data inside that. AttributedString

Simply, store your data into Document object and pass properties like Font, Bold, Italic everything in AttributedString.

Hope this will be helpful A quick tutorial And In depth tutorial

It's obvious why you'd want to disable this: To force IntelliJ to include each and every import individually. It makes it easier for people to figure out exactly where classes you're using come from.

Click on the Settings "wrench" icon on the toolbar, open "Imports" under "Code Style", and check the "Use single class import" selection. You can also completely remove entries under "Packages to use import with *", or specify a threshold value that only uses the "*" when the individual classes from a package exceeds that threshold.

Update: in IDEA 13 "Use single class import" does not prevent wildcard imports. The solution is to go to Preferences (? + , on macOS / Ctrl + Alt + S on Windows and Linux) > Editor > Code Style > Java > Imports tab set Class count to use import with '*' and Names count to use static import with '*' to a higher value. Any value over 99 seems to work fine.

Try this code. It's definitly working.

<?php
// Connection 

$conn=mysql_connect('localhost','root','');
$db=mysql_select_db('excel',$conn);

$filename = "Webinfopen.xls"; // File Name
// Download file
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$user_query = mysql_query('select name,work from info');
// Write data to file
$flag = false;
while ($row = mysql_fetch_assoc($user_query)) {
    if (!$flag) {
        // display field/column names as first row
        echo implode("\t", array_keys($row)) . "\r\n";
        $flag = true;
    }
    echo implode("\t", array_values($row)) . "\r\n";
}

I imagine this forum posting, which I quote fully below, should answer the question.

Inside a procedure, function, or trigger definition, or in a dynamic SQL statement (embedded in a host program):

BEGIN ATOMIC
 DECLARE example VARCHAR(15) ;
 SET example = 'welcome' ;
 SELECT *
 FROM   tablename
 WHERE  column1 = example ;
END

or (in any environment):

WITH t(example) AS (VALUES('welcome'))
SELECT *
FROM   tablename, t
WHERE  column1 = example

or (although this is probably not what you want, since the variable needs to be created just once, but can be used thereafter by everybody although its content will be private on a per-user basis):

CREATE VARIABLE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM   tablename
WHERE  column1 = example ;

To tell eclipse to use JDK, you have to follow the below steps.

1. Select the Window menu and then Select Preferences. You can see a dialog box.
2. Then select Java ---> Installed JRE’s
3. Then click Add and select Standard VM then click Next
4. In the JRE home, navigate to the folder you’ve installed the JDK (For example, in my system my JDK was in C:\Program Files\Java\jdk1.8.0_181\ )
5. Now click on Finish.

After completing the above steps, you are done now and eclipse will start using the selected JDK for compilation.

Actually my advice is to do all of these best practices.

• Put the documents outside the webroot OR in a directory denied access by the webserver AND
• Use a define in your visible documents that the hidden documents check for:

      if (!defined(INCL_FILE_FOO)) {
          header('HTTP/1.0 403 Forbidden');
          exit;
      }

This way if the files become misplaced somehow (an errant ftp operation) they are still protected.

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

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

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

which is the same as the -n

% git revert -n <commit hash>

While the other answers are correct, using the "-s" option will also show the file is empty even if the file does not exist.
By adding this additional check "-f" to see if the file exists first, we ensure the result is correct.

if [ -f diff.txt ]
then
  if [ -s diff.txt ]
  then
    rm -f empty.txt
    touch full.txt
  else
    rm -f full.txt
    touch empty.txt
  fi
else
  echo "File diff.txt does not exist"
fi

In Java you would do something similar to:

Transport transport = session.getTransport("smtps");
transport.connect (smtp_host, smtp_port, smtp_username, smtp_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();    

Note 'smtpS' protocol. Also socketFactory properties is no longer necessary in modern JVMs but you might need to set 'mail.smtps.auth' and 'mail.smtps.starttls.enable' to 'true' for Gmail. 'mail.smtps.debug' could be helpful too.

A different approach.
On the figure() call specify properties or modify the figure handle properties after h = figure().

This creates a full screen figure based on normalized units.
figure('units','normalized','outerposition',[0 0 1 1])

The units property can be adjusted to inches, centimeters, pixels, etc.

See figure documentation.

I personally like this version of FileUtils. Here's an example that finds all mp3s or flacs in a directory or any of its subdirectories:

String[] types = {"mp3", "flac"};
Collection<File> files2 = FileUtils.listFiles(/path/to/your/dir, types , true);

In SQL Server you would generally use. I don't know about other database engines.

select * from users where active = 0

I know your question is tagged as boostrap-modal (althought you didn't mentioned Bootstrap explicity neither), but I loved to see the simple way W3.CSS solved this and I think is good to share it.

  <img src="/myImage.png" style="width:30%;cursor:zoom-in"
  onclick="document.getElementById('modal01').style.display='block'">

  <div id="modal01" class="w3-modal" onclick="this.style.display='none'">
    <div class="w3-modal-content w3-animate-zoom">
      <img src="/myImage.png" style="width:100%">
    </div>
  </div>

I let you a link to the W3School modal image example to see the headers to make W3.CSS work.

It work for me

$request = new Request();
$request->headers->set('content-type', 'application/json');     
$request->initialize(['yourParam' => 2]);

check output

$queryParams = $request->query();
dd($queryParams['yourParam']); // 2

If you're going to be repeating this, might as well have an extension method:

// appends a string class to the html controls class attribute
public static void AddClass(this HtmlControl control, string newClass)
{
    if (control.Attributes["class"].IsNotNullAndNotEmpty())
    {
        control.Attributes["class"] += " " + newClass;
    }
    else
    {
        control.Attributes["class"] = newClass;
    }
}

This is with reference to @Ladislav Mrnka's answer on using fluent api for configuring one-to-one relationship.

Had a situation where having FK of dependent must be it's PK was not feasible.

E.g., Foo already has one-to-many relationship with Bar.

public class Foo {
   public Guid FooId;
   public virtual ICollection<> Bars; 
}
public class Bar {
   //PK
   public Guid BarId;
   //FK to Foo
   public Guid FooId;
   public virtual Foo Foo;
}

Now, we had to add another one-to-one relationship between Foo and Bar.

public class Foo {
   public Guid FooId;
   public Guid PrimaryBarId;// needs to be removed(from entity),as we specify it in fluent api
   public virtual Bar PrimaryBar;
   public virtual ICollection<> Bars;
}
public class Bar {
   public Guid BarId;
   public Guid FooId;
   public virtual Foo PrimaryBarOfFoo;
   public virtual Foo Foo;
}

Here is how to specify one-to-one relationship using fluent api:

modelBuilder.Entity<Bar>()
            .HasOptional(p => p.PrimaryBarOfFoo)
            .WithOptionalPrincipal(o => o.PrimaryBar)
            .Map(x => x.MapKey("PrimaryBarId"));

Note that while adding PrimaryBarId needs to be removed, as we specifying it through fluent api.

Also note that method name [WithOptionalPrincipal()][1] is kind of ironic. In this case, Principal is Bar. WithOptionalDependent() description on msdn makes it more clear.

The :before pseudo element isn't needed for the clearfix hack itself.

It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.

display:table is being used because display:block doesn't do the trick. Using display:block margins will collapse even with a :before element.

There is one caveat: if vertical-align:baseline is used in table cells with clearfixed <div> elements, Firefox won't align well. Then you might prefer using display:block despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

If the goal is to style the img after browser has rendered image, you should:

const img = new Image();
img.src = 'path/to/img.jpg';

img.decode().then(() => {
/* set styles */
/* add img to DOM */ 
});

because the browser first loads the compressed version of image, then decodes it, finally paints it. since there is no event for paint you should run your logic after browser has decoded the img tag.

I have crafted an alternative non-jQuery version:

document.cookie.match(/^(.*;)?\s*MyCookie\s*=\s*[^;]+(.*)?$/)

It only tests for cookie existence. A more complicated version can also return cookie value:

value_or_null = (document.cookie.match(/^(?:.*;)?\s*MyCookie\s*=\s*([^;]+)(?:.*)?$/)||[,null])[1]

Put your cookie name in in place of MyCookie.

How to correctly use moment.js durations? | Use moment.duration() in codes

First, you need to import moment and moment-duration-format.

import moment from 'moment';
import 'moment-duration-format';

Then, use duration function. Let us apply the above example: 28800 = 8 am.

moment.duration(28800, "seconds").format("h:mm a");

Well, you do not have above type error. Do you get a right value 8:00 am ? No…, the value you get is 8:00 a. Moment.js format is not working as it is supposed to.

The solution is to transform seconds to milliseconds and use UTC time.

moment.utc(moment.duration(value, 'seconds').asMilliseconds()).format('h:mm a')

All right we get 8:00 am now. If you want 8 am instead of 8:00 am for integral time, we need to do RegExp

const time = moment.utc(moment.duration(value, 'seconds').asMilliseconds()).format('h:mm a');
time.replace(/:00/g, '')

If your app targets Android N (7.0) and above, you should not use the answers above (of the "Uri.fromFile" method), because it won't work for you.

Instead, you should use a ContentProvider.

For example, if your image file is in external folder, you can use this (similar to the code I've made here) :

File file = ...;
final Intent intent = new Intent(Intent.ACTION_VIEW)//
                                    .setDataAndType(VERSION.SDK_INT >= VERSION_CODES.N ?
                                                    FileProvider.getUriForFile(this,getPackageName() + ".provider", file) : Uri.fromFile(file),
                            "image/*").addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

manifest:

<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/provider_paths"/>
</provider>

res/xml/provider_paths.xml :

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <!--<external-path name="external_files" path="."/>-->
    <external-path
        name="files_root"
        path="Android/data/${applicationId}"/>
    <external-path
        name="external_storage_root"
        path="."/>
</paths>

If your image is in the private path of the app, you should create your own ContentProvider, as I've created "OpenFileProvider" on the link.

I implemented a solution like Kamil Szot's, and it has an undesired effect. I have not enough reputation to post this as a comment, so I post it here in case someone is trying that solution and reads this.

The solution is:

interface MyInterface {
    Name: string;
}

const MyClass = class {
    static Name: string;
};

However, using a class expression doesn't allow me to use MyClass as a type. If I write something like:

const myInstance: MyClass;

myInstance turns out to be of type any, and my editor shows the following error:

'MyClass' refers to a value, but is being used as a type here. Did you mean 'typeof MyClass'?ts(2749)

I end up losing a more important typing than the one I wanted to achieve with the interface for the static part of the class.

Val's solution using a decorator avoids this pitfall.

In javascript without using jquery:

document.body.innerText = document.body.innerText.replace('actualword', 'replacementword');

If that's your whole string, then just try parsing it:

if (DateTime::createFromFormat('Y-m-d H:i:s', $myString) !== FALSE) {
  // it's a date
}

In SQL, a comparison between a null value and any other value (including another null) using a comparison operator (eg =, !=, <, etc) will result in a null, which is considered as false for the purposes of a where clause (strictly speaking, it's "not true", rather than "false", but the effect is the same).

The reasoning is that a null means "unknown", so the result of any comparison to a null is also "unknown". So you'll get no hit on rows by coding where my_column = null.

SQL provides the special syntax for testing if a column is null, via is null and is not null, which is a special condition to test for a null (or not a null).

Here's some SQL showing a variety of conditions and and their effect as per above.

create table t (x int, y int);
insert into t values (null, null), (null, 1), (1, 1);

select 'x = null' as test , x, y from t where x = null
union all
select 'x != null', x, y from t where x != null
union all
select 'not (x = null)', x, y from t where not (x = null)
union all
select 'x = y', x, y from t where x = y
union all
select 'not (x = y)', x, y from t where not (x = y);

returns only 1 row (as expected):

TEST    X   Y
x = y   1   1

See this running on SQLFiddle

Personally, I use ... | Out-Null because, as others have commented, that looks like the more "PowerShellish" approach compared to ... > $null and [void] .... $null = ... is exploiting a specific automatic variable and can be easy to overlook, whereas the other methods make it obvious with additional syntax that you intend to discard the output of an expression. Because ... | Out-Null and ... > $null come at the end of the expression I think they effectively communicate "take everything we've done up to this point and throw it away", plus you can comment them out easier for debugging purposes (e.g. ... # | Out-Null), compared to putting $null = or [void] before the expression to determine what happens after executing it.

Let's look at a different benchmark, though: not the amount of time it takes to execute each option, but the amount of time it takes to figure out what each option does. Having worked in environments with colleagues who were not experienced with PowerShell or even scripting at all, I tend to try to write my scripts in a way that someone coming along years later that might not even understand the language they're looking at can have a fighting chance at figuring out what it's doing since they might be in a position of having to support or replace it. This has never occurred to me as a reason to use one method over the others until now, but imagine you're in that position and you use the help command or your favorite search engine to try to find out what Out-Null does. You get a useful result immediately, right? Now try to do the same with [void] and $null =. Not so easy, is it?

Granted, suppressing the output of a value is a pretty minor detail compared to understanding the overall logic of a script, and you can only try to "dumb down" your code so much before you're trading your ability to write good code for a novice's ability to read...not-so-good code. My point is, it's possible that some who are fluent in PowerShell aren't even familiar with [void], $null =, etc., and just because those may execute faster or take less keystrokes to type, doesn't mean they're the best way to do what you're trying to do, and just because a language gives you quirky syntax doesn't mean you should use it instead of something clearer and better-known.^*

^* I am presuming that Out-Null is clear and well-known, which I don't know to be $true. Whichever option you feel is clearest and most accessible to future readers and editors of your code (yourself included), regardless of time-to-type or time-to-execute, that's the option I'm recommending you use.

As of today you can throttle your connection natively in Google Chrome Canary 46.0.2489.0. Simply open up Dev Tools and head over to the Network tab:

You can check like this:

int x;
cin >> x;

if (cin.fail()) {
    //Not an int.
}

Furthermore, you can continue to get input until you get an int via:

#include <iostream>



int main() {

    int x;
    std::cin >> x;
    while(std::cin.fail()) {
        std::cout << "Error" << std::endl;
        std::cin.clear();
        std::cin.ignore(256,'\n');
        std::cin >> x;
    }
    std::cout << x << std::endl;

    return 0;
}

EDIT: To address the comment below regarding input like 10abc, one could modify the loop to accept a string as an input. Then check the string for any character not a number and handle that situation accordingly. One needs not clear/ignore the input stream in that situation. Verifying the string is just numbers, convert the string back to an integer. I mean, this was just off the cuff. There might be a better way. This won't work if you're accepting floats/doubles (would have to add '.' in the search string).

#include <iostream>
#include <string>

int main() {

    std::string theInput;
    int inputAsInt;

    std::getline(std::cin, theInput);

    while(std::cin.fail() || std::cin.eof() || theInput.find_first_not_of("0123456789") != std::string::npos) {

        std::cout << "Error" << std::endl;

        if( theInput.find_first_not_of("0123456789") == std::string::npos) {
            std::cin.clear();
            std::cin.ignore(256,'\n');
        }

        std::getline(std::cin, theInput);
    }

    std::string::size_type st;
    inputAsInt = std::stoi(theInput,&st);
    std::cout << inputAsInt << std::endl;
    return 0;
}

This is because strings are immutable in Python.

Which means that X.replace("hello","goodbye") returns a copy of X with replacements made. Because of that you need replace this line:

X.replace("hello", "goodbye")

with this line:

X = X.replace("hello", "goodbye")

More broadly, this is true for all Python string methods that change a string's content "in-place", e.g. replace,strip,translate,lower/upper,join,...

You must assign their output to something if you want to use it and not throw it away, e.g.

X  = X.strip(' \t')
X2 = X.translate(...)
Y  = X.lower()
Z  = X.upper()
A  = X.join(':')
B  = X.capitalize()
C  = X.casefold()

and so on.

You can use the overloads method RedirectToAction(string actionName, string controllerName);

Example:

RedirectToAction(nameof(HomeController.Index), "Home");

For newer versions of Laravel, please replace protected $redirectTo = RouteServiceProvider::HOME; with protected $redirectTo = '/newurl'; and replace newurl accordingly.

Tested with Laravel version-6

You've got the syntax all wrong:

cursor.execute ("""
   UPDATE tblTableName
   SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
   WHERE Server=%s
""", (Year, Month, Day, Hour, Minute, ServerID))

For more, read the documentation.

There is another way. If you're passing an object by reference, that object's properties will appear in the function's local scope. I know this works for Safari (haven't checked other browsers) and I don't know if this feature has a name, but the below example illustrates its use.

Although in practice I don't think that this offers any functional value beyond the technique you're already using, it's a little cleaner semantically. And it still requires passing a object reference or an object literal.

function sum({ a:a, b:b}) {
    console.log(a+'+'+b);
    if(a==undefined) a=0;
    if(b==undefined) b=0;
    return (a+b);
}

// will work (returns 9 and 3 respectively)
console.log(sum({a:4,b:5}));
console.log(sum({a:3}));

// will not work (returns 0)
console.log(sum(4,5));
console.log(sum(4));

These are Unicode property shortcuts (\p{L} for Unicode letters, \p{N} for Unicode digits). They are supported by .NET, Perl, Java, PCRE, XML, XPath, JGSoft, Ruby (1.9 and higher) and PHP (since 5.1.0)

At any rate, that's a very strange regex. You should not be using alternation when a character class would suffice:

[\p{L}\p{N}_.-]*

I resolved this problem by separating my content into two tables.

One table is the header row.

The seconds is also <table> tag, but wrapped by <div> with static height and overflow scroll.

When installing Apache and PHP under Ubuntu 14.04, I needed to specifically enable php configs by issuing a2enmod php5-cgi

I have been working on this for some time now. Tough to get right, and I don't claim I do, but I'm happy with it so far. My code and several demos can be found at

• https://github.com/bauerca/drag-sort-listview

Its use is very similar to the TouchInterceptor (on which the code is based), although significant implementation changes have been made.

DragSortListView has smooth and predictable scrolling while dragging and shuffling items. Item shuffles are much more consistent with the position of the dragging/floating item. Heterogeneous-height list items are supported. Drag-scrolling is customizable (I demonstrate rapid drag scrolling through a long list---not that an application comes to mind). Headers/Footers are respected. etc.?? Take a look.

SELECT, INSERT, UPDATE, and DELETE commands frequently include WHERE clauses to specify filters that define the conditions each row in the source tables must meet to qualify for an SQL command. Parameters provide the filter values in the WHERE clauses.

You can use parameter markers to dynamically provide parameter values. The rules for which parameter markers and parameter names can be used in the SQL statement depend on the type of connection manager that the Execute SQL uses.

The following table lists examples of the SELECT command by connection manager type. The INSERT, UPDATE, and DELETE statements are similar. The examples use SELECT to return products from the Product table in AdventureWorks2012 that have a ProductID greater than and less than the values specified by two parameters.

EXCEL, ODBC, and OLEDB

SELECT* FROM Production.Product WHERE ProductId > ? AND ProductID < ?

ADO

SELECT * FROM Production.Product WHERE ProductId > ? AND ProductID < ?

ADO.NET

SELECT* FROM Production.Product WHERE ProductId > @parmMinProductID 
     AND ProductID < @parmMaxProductID

The examples would require parameters that have the following names: The EXCEL and OLED DB connection managers use the parameter names 0 and 1. The ODBC connection type uses 1 and 2. The ADO connection type could use any two parameter names, such as Param1 and Param2, but the parameters must be mapped by their ordinal position in the parameter list. The ADO.NET connection type uses the parameter names @parmMinProductID and @parmMaxProductID.

In my case Maximum call stack size exceeded was triggered by another error earlier. The logs looked like this:

I had to add --unsafe-perm to the install command and run it as root:

sudo npm install -g --unsafe-perm @aws-amplify/cli

You really should have multiple input, e.g. one for firstname, middle names, lastname and another one for age. If you want to have some fun though you could try:

>>> input_given="join smith 25"
>>> chars="".join([i for i in input_given if not i.isdigit()])
>>> age=input_given.translate(None,chars)
>>> age
'25'
>>> name=input_given.replace(age,"").strip()
>>> name
'join smith'

This would of course fail if there is multiple numbers in the input. a quick check would be:

assert(age in input_given)

and also:

assert(len(name)<len(input_given))

What features in github are you looking for?

If you don't want the collaboration, pull requests etc. but just want your own repositories to be viewable, git instaweb will create something for you.
