Programs & Examples On #Atomicity

In $CUDA_HOME/include/host_config.h, find lines like these (may slightly vary between different CUDA version):

//...
#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 9)

#error -- unsupported GNU version! gcc versions later than 4.9 are not supported!

#endif [> __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 9) <]
//...

Remove or change them matching your condition.

Note this method is potentially unsafe and may break your build. For example, gcc 5 uses C++11 as default, however this is not the case for nvcc as of CUDA 7.5. A workaround is to add

--Xcompiler="--std=c++98" for CUDA<=6.5

or

--std=c++11 for CUDA>=7.0.

To add to the other answers, I think the acronyms were derived to show a scale between the two terms to distinguish how reliable transactions or requests where between RDMS versus Big Data.

From this article acid vs base

In Chemistry, pH measures the relative basicity and acidity of an aqueous (solvent in water) solution. The pH scale extends from 0 (highly acidic substances such as battery acid) to 14 (highly alkaline substances like lie); pure water at 77° F (25° C) has a pH of 7 and is neutral.

Data engineers have cleverly borrowed acid vs base from chemists and created acronyms that while not exact in their meanings, are still apt representations of what is happening within a given database system when discussing the reliability of transaction processing.

One other point, since I work with Big Data using Elasticsearch. To clarify, an instance of Elasticsearch is a node and a group of nodes form a cluster.

To me from a practical standpoint, BA (Basically Available), in this context, has the idea of multiple master nodes to handle the Elasticsearch cluster and it's operations.

If you have 3 master nodes and the currently directing master node goes down, the system stays up, albeit in a less efficient state, and another master node takes its place as the main directing master node. If two master nodes go down, the system still stays up and the last master node takes over.

I understand that the answer is given but I wrote a simple example to make it easy to understand for beginners like me:

var x = { println("x"); 15 }
lazy val y = { println("y"); x + 1 }
println("-----")
x = 17
println("y is: " + y)

Output of above code is:

x
-----
y
y is: 18

As it can be seen, x is printed when it's initialized, but y is not printed when it's initialized in same way (I have taken x as var intentionally here - to explain when y gets initialized). Next when y is called, it's initialized as well as value of last 'x' is taken into consideration but not the old one.

Hope this helps.

In addition to the example given in the Advanced Bash Scripting Guide referenced by Jefromi, these examples show how pipes create subshells:

$ echo $$ $BASHPID | cat -
11656 31528
$ echo $$ $BASHPID
11656 11656
$ echo $$ | while read line; do echo $line $$ $BASHPID; done
11656 11656 31497
$ while read line; do echo $line $$ $BASHPID; done <<< $$
11656 11656 11656

I am using Window 7 and It was same problem with me,I am using Skype and Not start Apache, but finally solved this problem, and It's working now

Check connection setting In Skype click tools -> click option -> click Advanced -> click connection Unchecked port number and click Save.

Here is the small example

public class TryWithResource {

    public static void main(String[] args) {
        try (TestMe r = new TestMe()) {
            r.generalTest();
        } catch(Exception e) {
            System.out.println("From Exception Block");
        } finally {
            System.out.println("From Final Block");
        }
    }
}



public class TestMe implements AutoCloseable {

    @Override
    public void close() throws Exception {
        System.out.println(" From Close -  AutoCloseable  ");
    }

    public void generalTest() {
        System.out.println(" GeneralTest ");
    }
}

Here is the output:

GeneralTest 
From Close -  AutoCloseable  
From Final Block

if(c is TFrom)
{
   // Do Stuff
}

or if you plan on using c as a TForm, use the following example:

var tForm = c as TForm;
if(tForm != null)
{
   // c is of type TForm
}

The second example only needs to check to see if c is of type TForm once. Whereis if you check if see if c is of type TForm then cast it, the CLR undergoes an extra check. Here is a reference.

Edit: Stolen from Jon Skeet

If you want to make sure c is of TForm and not any class inheriting from TForm, then use

if(c.GetType() == typeof(TForm))
{
   // Do stuff cause c is of type TForm and nothing else
}

char a[2] defines an array of char's. a is a pointer to the memory at the beginning of the array and using == won't actually compare the contents of a with 'ab' because they aren't actually the same types, 'ab' is integer type. Also 'ab' should be "ab" otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.

Something that might be illustrative is looking at the typeid of 'ab':

#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
    int some_int =5;
    std::cout << typeid('ab').name() << std::endl;
    std::cout << typeid(some_int).name() << std::endl;
    return 0;
}

on my system this returns:

i
i

showing that 'ab' is actually evaluated as an int.

If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator == overloaded and will do a comparison check when called this way.

If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:

#include <iostream>
#include <string>
using namespace std;
int main(){
    string a;
    cout<<"enter ab ";
    cin>>a;
    if(a=="ab"){
         cout<<"correct";
    }
    return 0;
}

This one is due to:

if(a=='ab') , here, a is const char* type (ie : array of char)

'ab' is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.

Since char is a primitive type inherited from C, no operator == is defined.

the good code should be:

if(strcmp(a,"ab")==0) , then you'll compare a const char* to another const char* using strcmp.

You can also add a hover style to the dropdown.

This will work in C# 8 using a switch expresion

var message = "Some test message";

message = message switch
{
    string a when a.Contains("test") => "yes",
    string b when b.Contains("test2") => "yes for test2",
    _ => "nothing to say"
};

Update pandas 0.17.0

@7stud's answer for the newest pandas version would require to just call

s.plot( 
    kind='bar', 
    color=my_colors,
)

instead of

pd.Series.plot(
    s, 
    kind='bar', 
    color=my_colors,
)

The plotting functions have become members of the Series, DataFrame objects and in fact calling pd.Series.plot with a color argument gives an error

You can fix this by passing parameters rather than relying on Globals

def function(Var1, Var2): 
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    return Var1 - 1
function(1, 1)

Place your text file in the /assets directory under the Android project. Use AssetManager class to access it.

AssetManager am = context.getAssets();
InputStream is = am.open("test.txt");

Or you can also put the file in the /res/raw directory, where the file will be indexed and is accessible by an id in the R file:

InputStream is = context.getResources().openRawResource(R.raw.test);

std::copy does the job as far as moving elements is concerned:

 #include <algorithm>

 std::copy(array+3, array+5, array+2);

Note that the precondition for copy is that the destination must not be in the source range. It's permissible for the ranges to overlap.

Also, because of the way arrays work in C++, this doesn't "shorten" the array. It just shifts elements around within it. There is no way to change the size of an array, but if you're using a separate integer to track its "size" meaning the size of the part you care about, then you can of course decrement that.

So, the array you'll end up with will be as if it were initialized with:

int array[] = {1,2,4,5,5};

:set list in Vim will show whitespace. End of lines show as '$' and carriage returns usually show as '^M'.

open xcode -> general -> Embedded Binaries -> add QBImagepicker.framework and RSKImageCropper -> clean project

just add QBImagePicker.framework and RSKImageCropper.framework at embedded binaries worked for me

Try this: currentLoad = ConvertToLongInteger(oXLSheet2.Cells(4, 6).Value) with this function:

Function ConvertToLongInteger(ByVal stValue As String) As Long
 On Error GoTo ConversionFailureHandler
 ConvertToLongInteger = CLng(stValue)  'TRY to convert to an Integer value
 Exit Function           'If we reach this point, then we succeeded so exit

ConversionFailureHandler:
 'IF we've reached this point, then we did not succeed in conversion
 'If the error is type-mismatch, clear the error and return numeric 0 from the function
 'Otherwise, disable the error handler, and re-run the code to allow the system to 
 'display the error
 If Err.Number = 13 Then 'error # 13 is Type mismatch
      Err.Clear
      ConvertToLongInteger = 0
      Exit Function
 Else
      On Error GoTo 0
      Resume
 End If
End Function

I chose Long (Integer) instead of simply Integer because the min/max size of an Integer in VBA is crummy (min: -32768, max:+32767). It's common to have an integer outside of that range in spreadsheet operations.

The above code can be modified to handle conversion from string to-Integers, to-Currency (using CCur() ), to-Decimal (using CDec() ), to-Double (using CDbl() ), etc. Just replace the conversion function itself (CLng). Change the function return type, and rename all occurrences of the function variable to make everything consistent.

The default fonts are different across Windows, Mac, and Linux. As of VSCode 1.15.1, the default font settings can be found in the source code:

const DEFAULT_WINDOWS_FONT_FAMILY = 'Consolas, \'Courier New\', monospace';
const DEFAULT_MAC_FONT_FAMILY = 'Menlo, Monaco, \'Courier New\', monospace';
const DEFAULT_LINUX_FONT_FAMILY = '\'Droid Sans Mono\', \'Courier New\', monospace, \'Droid Sans Fallback\'';

Lambda Expression result

var storesList = context.Stores.Select(x => new { Value= x.name,Text= x.ID }).ToList();

The variable $_POST is automatically populated.

Try var_dump($_POST); to see the contents.

You can access individual values like this: echo $_POST["name"];

This, of course, assumes your form is using the typical form encoding (i.e. enctype=”multipart/form-data”

If your post data is in another format (e.g. JSON or XML, you can do something like this:

$post = file_get_contents('php://input');

and $post will contain the raw data.

Assuming you're using the standard $_POST variable, you can test if a checkbox is checked like this:

if(isset($_POST['myCheckbox']) && $_POST['myCheckbox'] == 'Yes')
{
     ...
}

If you have an array of checkboxes (e.g.

<form action="myscript.php" method="post">
  <input type="checkbox" name="myCheckbox[]" value="A" />val1<br />
  <input type="checkbox" name="myCheckbox[]" value="B" />val2<br />
  <input type="checkbox" name="myCheckbox[]" value="C" />val3<br />
  <input type="checkbox" name="myCheckbox[]" value="D" />val4<br />
  <input type="checkbox" name="myCheckbox[]" value="E" />val5
  <input type="submit" name="Submit" value="Submit" />
</form>

Using [ ] in the checkbox name indicates that the selected values will be accessed by PHP script as an array. In this case $_POST['myCheckbox'] won't return a single string but will return an array consisting of all the values of the checkboxes that were checked.

For instance, if I checked all the boxes, $_POST['myCheckbox'] would be an array consisting of: {A, B, C, D, E}. Here's an example of how to retrieve the array of values and display them:

  $myboxes = $_POST['myCheckbox'];
  if(empty($myboxes))
  {
    echo("You didn't select any boxes.");
  }
  else
  {
    $i = count($myboxes);
    echo("You selected $i box(es): <br>");
    for($j = 0; $j < $i; $j++)
    {
      echo $myboxes[$j] . "<br>";
    }
  }

You can create your own conversion function:

    static long ToLong(string lNumber)
    {
        if (string.IsNullOrEmpty(lNumber))
            throw new Exception("Not a number!");
        char[] chars = lNumber.ToCharArray();
        long result = 0;
        bool isNegative = lNumber[0] == '-';
        if (isNegative && lNumber.Length == 1)
            throw new Exception("- Is not a number!");

        for (int i = (isNegative ? 1:0); i < lNumber.Length; i++)
        {
            if (!Char.IsDigit(chars[i]))
            {
                if (chars[i] == '.' && i < lNumber.Length - 1 && Char.IsDigit(chars[i+1]))
                {
                    var firstDigit = chars[i + 1] - 48;
                    return (isNegative ? -1L:1L) * (result + ((firstDigit < 5) ? 0L : 1L));    
                }
                throw new InvalidCastException($" {lNumber} is not a valid number!");
            }
            result = result * 10 + ((long)chars[i] - 48L);
        }
        return (isNegative ? -1L:1L) * result;
    }

It can be improved further:

• performance wise
• make the validation stricter in the sense that it currently doesn't care if characters after first decimal aren't digits
• specify rounding behavior as parameter for conversion function. it currently does rounding

If you want to reload a ViewController initially loaded from a XIB, you can use the next UIViewController extension:

extension UIViewController {
    func reloadViewFromNib() {
        let parent = view.superview
        view.removeFromSuperview()
        view = nil
        parent?.addSubview(view) // This line causes the view to be reloaded 
    }
}

There's a much better way to achieve your desired result, using SQL Server's analytic (or windowing) functions.

SELECT DISTINCT Date, MAX(Score) OVER(PARTITION BY Date) FROM ScoresTable

If you need more than just the date and max score combinations, you can use ranking functions, eg:

SELECT  *
FROM    ScoresTable t
JOIN (   
    SELECT 
        ScoreId,
        ROW_NUMBER() OVER (PARTITION BY Date ORDER BY Score DESC) AS [Rank] 
        FROM ScoresTable
) window ON window.ScoreId = p.ScoreId AND window.[Rank] = 1

You may want to use RANK() instead of ROW_NUMBER() if you want multiple records to be returned if they both share the same MAX(Score).

Uri is serializable, so you can save strings and convert it back when loading

when saving

String str = myUri.toString();

and when loading

Uri myUri = Uri.parse(str);

While most people will tell you to just use multiple repositories, I feel it's worth mentioning there are other solutions.

Solution 1

A single repository can contain multiple independent branches, called orphan branches. Orphan branches are completely separate from each other; they do not share histories.

git checkout --orphan BRANCHNAME

This creates a new branch, unrelated to your current branch. Each project should be in its own orphaned branch.

Now for whatever reason, git needs a bit of cleanup after an orphan checkout.

rm .git/index
rm -r *

Make sure everything is committed before deleting

Once the orphan branch is clean, you can use it normally.

Solution 2

Avoid all the hassle of orphan branches. Create two independent repositories, and push them to the same remote. Just use different branch names for each repo.

# repo 1
git push origin master:master-1

# repo 2
git push origin master:master-2

How about using the Dynamic data template that comes with Visual Studio. This could be hosted on IIS.

This walkthrough shows you how to create a basic Web site that uses ASP.NET Dynamic Data. Dynamic Data enables you to create a data-driven Web site with little or no coding.

This is a bit hacky but cross browser solution which requires no CSS

The connectivity plugin states in its docs that it only provides information if there is a network connection, but not if the network is connected to the Internet

Note that on Android, this does not guarantee connection to Internet. For instance, the app might have wifi access but it might be a VPN or a hotel WiFi with no access.

You can use

import 'dart:io';
...
try {
  final result = await InternetAddress.lookup('google.com');
  if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
    print('connected');
  }
} on SocketException catch (_) {
  print('not connected');
}

on sql 2008 this is valid

DECLARE @myVariable nvarchar(Max) = 'John said to Emily "Hey there Emily"'
select @myVariable

on sql server 2005, you need to do this

DECLARE @myVariable nvarchar(Max) 
select @myVariable = 'John said to Emily "Hey there Emily"'
select @myVariable

Press Ctl+T will open a search box. Delete # symbol and enter your file name.

If you're using an OS (like OS X) that doesn't have the dos2unix command but does have a Python interpreter (version 2.5+), this command is equivalent to the dos2unix command:

python -c "import sys; import fileinput; sys.stdout.writelines(line.replace('\r', '\n') for line in fileinput.input(mode='rU'))"

This handles both named files on the command line as well as pipes and redirects, just like dos2unix. If you add this line to your ~/.bashrc file (or equivalent profile file for other shells):

alias dos2unix="python -c \"import sys; import fileinput; sys.stdout.writelines(line.replace('\r', '\n') for line in fileinput.input(mode='rU'))\""

... the next time you log in (or run source ~/.bashrc in the current session) you will be able to use the dos2unix name on the command line in the same manner as in the other examples.

If you highlight the method Assert.assertEquals(val1, val2) and hit Ctrl + Shift + M (Add Import), it will add it as a static import, at least in Eclipse 3.4.

I had the same problem with Entity Framework database first on all CLOB columns.

As a workaround, I filled the text values with spaces to be at least 4000 in width in insert operations (did not come with any better solution).

The solution for the error is to add this line at the top of the code:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

Using keySet-

id1.keySet().stream()
        .filter(x -> x == 1)
        .map(x -> id1.get(x))
        .collect(Collectors.toList())

Offering another potential solution to this error.

If you have a frontend application that makes API calls to the backend, make sure you reference the domain name that the certificate has been issued to.

e.g.

https://example.com/api/etc

and not

https://123.4.5.6/api/etc

In my case, I was making API calls to a secure server with a certificate, but using the IP instead of the domain name. This threw a Failed to load resource: net::ERR_INSECURE_RESPONSE.

No hard coded values.

No JavaScript.

No approximations.

The trick is to use a hidden & duplicated div to get the browser to understand what 100% means.

This method is suitable whenever you're able to duplicate the DOM of the element you wish to animate.

I had the same issue (mysql 5.6 on mac) with 'can't rmdir..'-errors when dropping databases. Leaving an empty database directory not possible to get rid of. Thanks @Framework and @Beel for the solutions.

I first deleted the db directory from the Terminal in (/Applications/XAMPP/xamppfiles/var/mysql).

For further db drops, I also deleted the empty test file. In my case the file was called NOTEMPTY but still containing 0:

sudo ls -al test
total 0
drwxrwx---   3 _mysql  _mysql  102 Mar 26 16:50 .
drwxrwxr-x  18 _mysql  _mysql  612 Apr  7 13:34 ..
-rw-rw----   1 _mysql  _mysql    0 Jun 26  2013 NOTEMPTY

Chmod first and then

sudo rm -rf test/NOTEMPTY

No problems dropping databases after that

With library(lubridate), numeric representations of date and time saved as the number of seconds since 1970-01-01 00:00:00 UTC, can be coerced into dates with as_datetime():

lubridate::as_datetime(1352068320)

[1] "2012-11-04 22:32:00 UTC"

In this case you want to "calculate" a pixel value depending of an object property.

I would define a function in the controller that calculates the pixel values.

In the controller:

$scope.GetHeight = function(aspect) {
   if(bla bla bla) return 270;
   return 360;
}

Then in your template you just write:

element height="{{ GetHeight(aspect) }}px "

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

You can create an element with an id and then assign that length value to that element.

var name = prompt("What's your name?");_x000D_
var lengthOfName = name.length_x000D_
document.getElementById('message').innerHTML = lengthOfName;

<p id='message'></p>

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

slapcat > backup.ldif

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

You need to add extra nginx directive (for ngx_http_proxy_module) in nginx.conf, e.g.:

proxy_read_timeout 300;

Basically the nginx proxy_read_timeout directive changes the proxy timeout, the FcgidIOTimeout is for scripts that are quiet too long, and FcgidBusyTimeout is for scripts that take too long to execute.

Also if you're using FastCGI application, increase these options as well:

FcgidBusyTimeout 300
FcgidIOTimeout 250

Then reload nginx and PHP5-FPM.

Plesk

In Plesk, you can add it in Web Server Settings under Additional nginx directives.

For FastCGI check in Web Server Settings under Additional directives for HTTP.

^{See: How to fix FastCGI timeout issues in Plesk?}

I found myself in a similar situation where I had to remove every n^th element in a given List<T>.

for (int i = 0, j = 0, n = 3; i < list.Count; i++)
{
    if ((j + 1) % n == 0) //Check current iteration is at the nth interval
    {
        list.RemoveAt(i);
        j++; //This extra addition is necessary. Without it j will wrap
             //down to zero, which will throw off our index.
    }
    j++; //This will always advance the j counter
}

As explained, it is not possible. If you want to use a method of the subclass, evaluate the possibility to add the method to the superclass (may be empty) and call from the subclasses getting the behaviour you want (subclass) thanks to polymorphism. So when you call d.method() the call will succeed withoug casting, but in case the object will be not a dog, there will not be a problem

I was also struggling with this problem, and find that the best way is to use a CURSOR.

I have tried Denis solution with OUTPUT, but as he mentiond, it's impossible to output external columns in an insert statement, and the MERGE can't work when insert multiple rows by select.

So, i've used a CURSOR, for each row in the outer table, i've done a INSERT, then use the @@IDENTITY for another INSERT.

DECLARE @OuterID int

DECLARE MY_CURSOR CURSOR 
  LOCAL STATIC READ_ONLY FORWARD_ONLY
FOR 
SELECT  ID FROM   [external_Table]

OPEN MY_CURSOR
FETCH NEXT FROM MY_CURSOR INTO @OuterID

WHILE @@FETCH_STATUS = 0
BEGIN 
INSERT INTO [Table]   (data)
    SELECT data
    FROM     [external_Table] where ID = @OuterID 

    INSERT INTO [second_table] (FK,OuterID)
    VALUES(@OuterID,@@identity)

    FETCH NEXT FROM MY_CURSOR INTO @OuterID
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR

Parameters starting with - or -- are usually considered optional. All other parameters are positional parameters and as such required by design (like positional function arguments). It is possible to require optional arguments, but this is a bit against their design. Since they are still part of the non-positional arguments, they will still be listed under the confusing header “optional arguments” even if they are required. The missing square brackets in the usage part however show that they are indeed required.

See also the documentation:

In general, the argparse module assumes that flags like -f and --bar indicate optional arguments, which can always be omitted at the command line.

Note: Required options are generally considered bad form because users expect options to be optional, and thus they should be avoided when possible.

That being said, the headers “positional arguments” and “optional arguments” in the help are generated by two argument groups in which the arguments are automatically separated into. Now, you could “hack into it” and change the name of the optional ones, but a far more elegant solution would be to create another group for “required named arguments” (or whatever you want to call them):

parser = argparse.ArgumentParser(description='Foo')
parser.add_argument('-o', '--output', help='Output file name', default='stdout')
requiredNamed = parser.add_argument_group('required named arguments')
requiredNamed.add_argument('-i', '--input', help='Input file name', required=True)
parser.parse_args(['-h'])

usage: [-h] [-o OUTPUT] -i INPUT

Foo

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        Output file name

required named arguments:
  -i INPUT, --input INPUT
                        Input file name

Using the document.title is how you would accomplish it in JavaScript, but how is this supposed to assist with SEO? Bots don't generally execute javascript code as they traverse through pages.

Its even easier than that.

<style name="MyTextStyle">
    <item name="android:textCursorDrawable">#000000</item>
</style>

This works in ICS and beyond. I haven't tested it in other versions.

[Late answer but hopefully usefull]

Using system tables doesn't always give 100% correct results because there might be a possibility that some stored procedures and/or views are encrypted in which case you'll need to use DAC connection to get the data you need.

I'd recommend using a third party tool such as ApexSQL Search that can deal with encrypted objects easily.

Syscomments system table will give null value for text column in case object is encrypted.

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

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

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

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

now,
paste this code in a module

Sub main()

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

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

            .TEXT              .VALUE             .VALUE2

If you're going to be adding to this dictionary frequently you'd want to take a class based approach, something similar to @Latty's answer in this SO question 2d-dictionary-with-many-keys-that-will-return-the-same-value.

However, if you have a static dictionary, and you need only access values by multiple keys then you could just go the very simple route of using two dictionaries. One to store the alias key association and one to store your actual data:

alias = {
    'a': 'id1',
    'b': 'id1',
    'c': 'id2',
    'd': 'id2'
}

dictionary = {
    'id1': 1,
    'id2': 2
}

dictionary[alias['a']]

If you need to add to the dictionary you could write a function like this for using both dictionaries:

def add(key, id, value=None)
    if id in dictionary:
        if key in alias:
            # Do nothing
            pass
        else:
            alias[key] = id
    else:
        dictionary[id] = value
        alias[key] = id

add('e', 'id2')
add('f', 'id3', 3)

While this works, I think ultimately if you want to do something like this writing your own data structure is probably the way to go, though it could use a similar structure.

If you want to do this in jQuery instead of CSS, you basically follow the same process.

Assuming you have some <div id="target"></div>, you can use the following code:

$("#target").hover(function() {
    $(this).css('cursor','pointer');
}, function() {
    $(this).css('cursor','auto');
});

and that should do it.

DisplayFor is also useful for templating. You could write a template for your Model, and do something like this:

@Html.DisplayFor(m => m)

Similar to @Html.EditorFor(m => m). It's useful for the DRY principal so that you don't have to write the same display logic over and over for the same Model.

Take a look at this blog on MVC2 templates. It's still very applicable to MVC3:

http://www.dalsoft.co.uk/blog/index.php/2010/04/26/mvc-2-templates/

It's also useful if your Model has a Data annotation. For instance, if the property on the model is decorated with the EmailAddress data annotation, DisplayFor will render it as a mailto: link.

You may want to look into os dependent line separators, e.g.:

import os

with open('./output.txt', 'a') as f1:
    f1.write(content + os.linesep)

Below shared for specific given property

searchContent:function(s, arr,propertyName){
            var matches = [];
            var propertyNameString=this.propertyNameToStr(propertyName);
            for (var i = arr.length; i--; ){
                if((""+Object.getOwnPropertyDescriptor(arr[i], propertyNameString).value).indexOf(s) > -1)
                    matches.push(arr[i]);
            }
            return matches;
        },
    propertyNameToStr: function (propertyFunction) {
            return /\.([^\.;]+);?\s*\}$/.exec(propertyFunction.toString())[1];
    }

//usage as below

result=$localStorage.searchContent(cabNo,appDataObj.getAll(),function() { dummy.cabDriverName; })

For me I had issues with history and location... As the accepted answer using window before history and location (i.e) window.history and window.location solved mine

composer create-project laravel/laravel=4.1.27 your-project-name --prefer-dist

And then you probably need to install all of vendor packages, so

composer install

You don't need to bother with that. Just write

<input type="text" name="email" placeholder="[email protected]" size="30">

replace the value with placeholder

Since this is an open-ended question, I will just give you an idea of how I would go about implementing something like this myself.

<span class="inputname">
    Project Images:
    <a href="#" class="add_project_file">
        <img src="images/add_small.gif" border="0" />
    </a>
</span>

<ul class="project_images">
    <li><input name="upload_project_images[]" type="file" /></li>
</ul>

Wrapping the file inputs inside li elements allows to easily remove the parent of our 'remove' links when clicked. The jQuery to do so is close to what you have already:

// Add new input with associated 'remove' link when 'add' button is clicked.
$('.add_project_file').click(function(e) {
    e.preventDefault();

    $(".project_images").append(
        '<li>'
      + '<input name="upload_project_images[]" type="file" class="new_project_image" /> '
      + '<a href="#" class="remove_project_file" border="2"><img src="images/delete.gif" /></a>'
      + '</li>');
});

// Remove parent of 'remove' link when link is clicked.
$('.project_images').on('click', '.remove_project_file', function(e) {
    e.preventDefault();

    $(this).parent().remove();
});

list.setOnTouchListener(new OnTouchListener() {
    // Setting on Touch Listener for handling the touch inside ScrollView
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // Disallow the touch request for parent scroll on touch of child view
        v.getParent().requestDisallowInterceptTouchEvent(true);
        return false;
    }
});

Try the SetField method:

table.Rows[i].SetField(column, value);
table.Rows[i].SetField(columnIndex, value);
table.Rows[i].SetField(columnName, value);

This should get the job done and is a bit "cleaner" than using Rows[i][j].

I think this is the syntax you are looking for:

if [ -z != $errorstatus ] 
then
commands
else
commands
fi

As Explains in here, you can do it with a simple steps:

By default, word jumps (option + ? or ?) and word deletions (option + backspace) do not work. To enable these, go to "iTerm ? Preferences ? Profiles ? Keys ? Load Preset... ? Natural Text Editing ? Boom! Head explodes"

I had to update the proxy settings under Plugins -> Plugin Manager -> Show Plugin Manager -> Settings to see any PlugIns in the "Available" list.

After that, installing "XML Tools" was easy and did the requested job as described above.

You need to attach a click event handler and clear the contents of the textarea from that handler.

HTML

<input type="button" value="Clear" id="clear"> 
<textarea id='output' rows=20 cols=90></textarea>

JS

var input = document.querySelector('#clear');
var textarea = document.querySelector('#output');

input.addEventListener('click', function () {
    textarea.value = '';
}, false);

and here's the working demo.

Explaining if any one want to send some parameters while calling stored procedure as below,

using (SqlConnection con = new SqlConnection(connetionString))
            {
                using (var command = new SqlCommand(storedProcName, con))
                {
                    foreach (var item in sqlParams)
                    {
                        item.Direction = ParameterDirection.Input;
                        item.DbType = DbType.String;
                        command.Parameters.Add(item);
                    }
                    command.CommandType = CommandType.StoredProcedure;
                    using (var adapter = new SqlDataAdapter(command))
                    {
                        adapter.Fill(dt);
                    }
                }
            }

The user-agent should be specified as a field in the header.

Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent.

If you're using requests v2.13 and newer

The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:

import requests

url = 'SOME URL'

headers = {
    'User-Agent': 'My User Agent 1.0',
    'From': '[email protected]'  # This is another valid field
}

response = requests.get(url, headers=headers)

If you're using requests v2.12.x and older

Older versions of requests clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.

import requests

url = 'SOME URL'

# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()

# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
    {
        'User-Agent': 'My User Agent 1.0',
    }
)

response = requests.get(url, headers=headers)

The syntax for crontab

* * * * * 

Minute(0-59) Hour(0-24) Day_of_month(1-31) Month(1-12) Day_of_week(0-6) Command_to_execute

Your syntax

* 22 * * * test > /dev/null

your job will Execute every minute at 22:00 hrs all week, month and year.

adding an option (0-59) at the minute place will run it once at 22:00 hrs all week, month and year.

0 22 * * * command_to_execute

Fortunately, if you are using Angular 5.1+, you do not need to implement a hack anymore as native support has been added. You just need to set onSameUrlNavigation to 'reload' in the RouterModule options :

@ngModule({
 imports: [RouterModule.forRoot(routes, {onSameUrlNavigation: ‘reload’})],
 exports: [RouterModule],
 })

There is no built-in auto_increment in Oracle.

You need to use sequences and triggers.

Read here how to do it right. (Step-by-step how-to for "Creating auto-increment columns in Oracle")

The & means that the function accepts the address (or reference) to a variable, instead of the value of the variable.

For example, note the difference between this:

void af(int& g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

And this (without the &):

void af(int g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

You have to actively choose to install MSYS to get the make.exe. So you should always have at least (the native) mingw32-make.exe if MinGW was installed properly. And if you installed MSYS you will have make.exe (in the MSYS subfolder probably).

Note that many projects require first creating a makefile (e.g. using a configure script or automake .am file) and it is this step that requires MSYS or cygwin. Makes you wonder why they bothered to distribute the native make at all.

Once you have the makefile, it is unclear if the native executable requires a different path separator than the MSYS make (forward slashes vs backward slashes). Any autogenerated makefile is likely to have unix-style paths, assuming the native make can handle those, the compiled output should be the same.

You can also use DBMS_METADATA:

select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY', 'PADCAMPAIGN') 
from dual

If you know the width of the span you could just stuff in a left margin.

Try this:

.center { text-align: center}
div.center span { display: table; }

Add the "center: class to your .

If you want some spans centered, but not others, replace the "div.center span" in your style sheet to a class (e.g "center-span") and add that class to the span.

Or the minified version of the file...

<script src="angular-route.min.js"></script>

More information about this here:

"This error occurs when a module fails to load due to some exception. The error message above should provide additional context."

"In AngularJS 1.2.0 and later, ngRoute has been moved to its own module. If you are getting this error after upgrading to 1.2.x, be sure that you've installed ngRoute."

If you only have php code in one html file but have multiple other files that only contain html code, you can add the following to your .htaccess file so it will only serve that particular file as php.

<Files yourpage.html>
AddType application/x-httpd-php .html 
//you may need to use x-httpd-php5 if you are using php 5 or higher
</Files>

This will make the PHP executable ONLY on the "yourpage.html" file and not on all of your html pages which will prevent slowdown on your entire server.

As to why someone might want to serve php via an html file, I use the IMPORTHTML function in google spreadsheets to import JSON data from an external url that must be parsed with php to clean it up and build an html table. So far I haven't found any way to import a .php file into google spreadsheets so it must be saved as an .html file for the function to work. Being able to serve php via an .html file is necessary for that particular use.

I followed approach as shown in code below to return a dictionary. Created a class and declared dictionary as global and created a function to add value corresponding to some keys in dictionary.

**Note have used Python 2.7 so some minor modification might be required for Python 3+

class a:
    global d
    d={}
    def get_config(self,x):
        if x=='GENESYS':
            d['host'] = 'host name'
            d['port'] = '15222'
        return d

Calling get_config method using class instance in a separate python file:

from constant import a
class b:
    a().get_config('GENESYS')
    print a().get_config('GENESYS').get('host')
    print a().get_config('GENESYS').get('port')

While writing to S3, you need to specify the length of S3 object to be sure that there are no out of memory errors.

Using IOUtils.toByteArray(stream) is also prone to OOM errors because this is backed by ByteArrayOutputStream

So, the best option is to first write the inputstream to a temp file on local disk and then use that file to write to S3 by specifying the length of temp file.

YourString.Substring(YourString.LastIndexOf("-"));

What you (probably want) are Flex 2.5.4 (some people are now "maintaining" it and producing newer versions, but IMO they've done more to screw it up than fix any real shortcomings) and byacc 1.9 (likewise). (Edit 2017-11-17: Flex 2.5.4 is not available on Sourceforge any more, and the Flex github repository only goes back to 2.5.5. But you can apparently still get it from a Gnu ftp server at ftp://ftp.gnu.org/old-gnu/gnu-0.2/src/flex-2.5.4.tar.gz.)

Since it'll inevitably be recommended, I'll warn against using Bison. Bison was originally written by Robert Corbett, the same guy who later wrote Byacc, and he openly states that at the time he didn't really know or understand what he was doing. Unfortunately, being young and foolish, he released it under the GPL and now the GPL fans push it as the answer to life's ills even though its own author basically says it should be thought of as essentially a beta test product -- but by the convoluted reasoning of GPL fans, byacc's license doesn't have enough restrictions to qualify as "free"!

see this http://stleary.github.io/JSON-java/org/json/JSONObject.html#JSONObject-java.lang.String-

JSONObject

public JSONObject(java.lang.String source)
           throws JSONException

Construct a JSONObject from a source JSON text string. This is the most commonly used` JSONObject constructor.

Parameters:
    source - `A string beginning with { (left brace) and ending with } (right brace).` 
Throws:
    JSONException - If there is a syntax error in the source string or a duplicated key.

you try to use some thing like:

new JSONObject("{your string}")

If you don't want to keep strings out of it, this works as well (Put it into a function):

DECLARE @Day int, @Month int, @Year int
SELECT @Day = 1, @Month = 2, @Year = 2008

SELECT DateAdd(dd, @Day-1, DateAdd(mm, @Month -1, DateAdd(yy, @Year - 2000, '20000101')))

With Object.fromEntries, you can convert from Array to Object:

var entries = [_x000D_
  ['cardType', 'iDEBIT'],_x000D_
  ['txnAmount', '17.64'],_x000D_
  ['txnId', '20181'],_x000D_
  ['txnType', 'Purchase'],_x000D_
  ['txnDate', '2015/08/13 21:50:04'],_x000D_
  ['respCode', '0'],_x000D_
  ['isoCode', '0'],_x000D_
  ['authCode', ''],_x000D_
  ['acquirerInvoice', '0'],_x000D_
  ['message', ''],_x000D_
  ['isComplete', 'true'],_x000D_
  ['isTimeout', 'false']_x000D_
];_x000D_
var obj = Object.fromEntries(entries);_x000D_
console.log(obj);

Try this:

myfile %>% mutate(V5 = (V1 == 1 & V2 != 4) + 2 * (V2 == 4 & V3 != 1))

giving:

  V1 V2 V3 V4 V5
1  1  2  3  5  1
2  2  4  4  1  2
3  1  4  1  1  0
4  4  5  1  3  0
5  5  5  5  4  0

or this:

myfile %>% mutate(V5 = ifelse(V1 == 1 & V2 != 4, 1, ifelse(V2 == 4 & V3 != 1, 2, 0)))

giving:

  V1 V2 V3 V4 V5
1  1  2  3  5  1
2  2  4  4  1  2
3  1  4  1  1  0
4  4  5  1  3  0
5  5  5  5  4  0

Note

Suggest you get a better name for your data frame. myfile makes it seem as if it holds a file name.

Above used this input:

myfile <- 
structure(list(V1 = c(1L, 2L, 1L, 4L, 5L), V2 = c(2L, 4L, 4L, 
5L, 5L), V3 = c(3L, 4L, 1L, 1L, 5L), V4 = c(5L, 1L, 1L, 3L, 4L
)), .Names = c("V1", "V2", "V3", "V4"), class = "data.frame", row.names = c("1", 
"2", "3", "4", "5"))

Update 1 Since originally posted dplyr has changed %.% to %>% so have modified answer accordingly.

Update 2 dplyr now has case_when which provides another solution:

myfile %>% 
       mutate(V5 = case_when(V1 == 1 & V2 != 4 ~ 1, 
                             V2 == 4 & V3 != 1 ~ 2,
                             TRUE ~ 0))

I was having the issue after select the deny when it asks for permission

After some search I got it fixed by restarting the system.

Here's a solution that doesn't use JS at all. It uses checkboxes instead.

You can hide the checkbox by adding this to your CSS:

.container input{
    display: none;
}

And then add some styling to make it look like a button.

Here's the source code that I modded.

I know some people use Django specifically as an interface to abstract this type of database interaction. Django provides utilities that can be used for this:

from django.utils import timezone
now_aware = timezone.now()

You do need to set up a basic Django settings infrastructure, even if you are just using this type of interface (in settings, you need to include USE_TZ=True to get an aware datetime).

By itself, this is probably nowhere near enough to motivate you to use Django as an interface, but there are many other perks. On the other hand, if you stumbled here because you were mangling your Django app (as I did), then perhaps this helps...

You can pass it to view but first query it in controller, and then after that add this :

return view('yourview', COMPACT('variabelnametobepassedtoview'));

Here is another alternative for adding leading to 0s to strings such as CUSIPs which can sometimes look like a number and which many applications such as Excel will corrupt and remove the leading 0s or convert them to scientific notation.

When I tried the answer provided by @metasequoia the vector returned had leading spaces and not 0s. This was the same problem mentioned by @user1816679 -- and removing the quotes around the 0 or changing from %d to %s did not make a difference either. FYI, I am using RStudio Server running on an Ubuntu Server. This little two-step solution worked for me:

gsub(pattern = " ", replacement = "0", x = sprintf(fmt = "%09s", ids[,CUSIP]))

using the %>% pipe function from the magrittr package it could look like this:

sprintf(fmt = "%09s", ids[,CUSIP]) %>% gsub(pattern = " ", replacement = "0", x = .)

I'd prefer a one-function solution, but it works.

Maybe there's still something that can be added, a small example with Django rest_framework, and decorators. This provides an answer to the implicit question: "why would I want this anyway?"

As said: we're with Django rest_framework, and we're using generic views, and for each type of objects in our database we find ourselves with one view class providing GET and POST for lists of objects, and an other view class providing GET, PUT, and DELETE for individual objects.

Now the POST, PUT, and DELETE we want to decorate with Django's login_required. Notice how this touches both classes, but not all methods in either class.

A solution could go through multiple inheritance.

from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import login_required

class LoginToPost:
    @method_decorator(login_required)
    def post(self, arg, *args, **kwargs):
        super().post(arg, *args, **kwargs)

Likewise for the other methods.

In the inheritance list of my concrete classes, I would add my LoginToPost before ListCreateAPIView and LoginToPutOrDelete before RetrieveUpdateDestroyAPIView. My concrete classes' get would stay undecorated.

Not adding the correct import delcaration can also be an obvious miss. For me, I had simply omitted to import PriorityUIKit.

I would suggest that you use a dictionary like so:

arr = {}

arr[1] = (1, 2, 4)
arr[18] = (3, 4, 5)

print(arr[1])
>>> (1, 2, 4)

If you're not sure an entry is defined in the dictionary, you'll need a validation mechanism when calling "arr[x]", e.g. try-except.

Hope this will help someone... Here's a little PHP script I wrote in case you need to copy some columns but not others, and/or the columns are not in the same order on both tables. As long as the columns are named the same, this will work. So if table A has [userid, handle, something] and tableB has [userID, handle, timestamp], then you'd "SELECT userID, handle, NOW() as timestamp FROM tableA", then get the result of that, and pass the result as the first parameter to this function ($z). $toTable is a string name for the table you're copying to, and $link_identifier is the db you're copying to. This is relatively fast for small sets of data. Not suggested that you try to move more than a few thousand rows at a time this way in a production setting. I use this primarily to back up data collected during a session when a user logs out, and then immediately clear the data from the live db to keep it slim.

 function mysql_multirow_copy($z,$toTable,$link_identifier) {
            $fields = "";
            for ($i=0;$i<mysql_num_fields($z);$i++) {
                if ($i>0) {
                    $fields .= ",";
                }
                $fields .= mysql_field_name($z,$i);
            }
            $q = "INSERT INTO $toTable ($fields) VALUES";
            $c = 0;
            mysql_data_seek($z,0); //critical reset in case $z has been parsed beforehand. !
            while ($a = mysql_fetch_assoc($z)) {
                foreach ($a as $key=>$as) {
                    $a[$key] = addslashes($as);
                    next ($a);
                }
                if ($c>0) {
                    $q .= ",";
                }
                $q .= "('".implode(array_values($a),"','")."')";
                $c++;
            }
            $q .= ";";
            $z = mysql_query($q,$link_identifier);
            return ($q);
        }

jQuery Templates is an example of something that uses this method to store HTML that will not be rendered directly (that’s the whole point) inside other HTML: http://api.jquery.com/jQuery.template/

Also, from API level 21 this is possible:

int random = ThreadLocalRandom.current().nextInt(min, max);

Place your widget.js after core.js, but before any other jquery that calls the widget.js file. (Example: draggable.js) Precedence (order) matters in what javascript/jquery can 'see'. Always position helper code before the code that uses the helper code.

This answer is based upon Matifou's answer.

First I modified it to ensure that I don't get the freq column returned as a scientific notation column by using the scipen option.

Then I multiple the answer by 100 to get a percent rather than decimal to make the freq column easier to read as a percentage.

getOption("scipen") 
options("scipen"=10) 
mtcars %>%
count(am, gear) %>% 
mutate(freq = (n / sum(n)) * 100)

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

Here's a function that returns substring of a given substring when start and end indices are provided. For complete reference you can visit the links given below.

func substring(string: String, fromIndex: Int, toIndex: Int) -> String? {
    if fromIndex < toIndex && toIndex < string.count /*use string.characters.count for swift3*/{
        let startIndex = string.index(string.startIndex, offsetBy: fromIndex)
        let endIndex = string.index(string.startIndex, offsetBy: toIndex)
        return String(string[startIndex..<endIndex])
    }else{
        return nil
    }
}

Here's a link to the blog post that I have created to deal with string manipulation in swift. String manipulation in swift (Covers swift 4 as well)

Or you can see this gist on github

or

$text1= 'From time to "time"';

Yes, given an array, array, and a value, item to search for, you can use np.where as:

itemindex = numpy.where(array==item)

The result is a tuple with first all the row indices, then all the column indices.

For example, if an array is two dimensions and it contained your item at two locations then

array[itemindex[0][0]][itemindex[1][0]]

would be equal to your item and so would be:

array[itemindex[0][1]][itemindex[1][1]]

Try explicitly enumerating the results by calling ToList().

Change

foreach (var item in query)

to

foreach (var item in query.ToList())

1. Function imageMorph will create a new img element therefore the id is removed. Changed to

   $("#wrapper > img")

2. You should use live() function for click event if you want you rocket lanch again.

all answers are 100% correct and well explained, but i did something good and very simple to make it responsive.

here the element will take 100% height of view port but when it comes to mobile view it don't look good specially on portrait view ( mobile ), so when view port is getting smaller the element will collapse and overlap on each other. so to make it little responsive here is code. hope someone will get help from this.

You have to create Different values folder for different screens . Like

values-sw720dp          10.1” tablet 1280x800 mdpi

Different values folders in android

http://android-developers.blogspot.in/2011/07/new-tools-for-managing-screen-sizes.html

Edited By @humblerookie

You can make use of Android Studio plugin called Dimenify to auto generate dimension values for other pixel buckets based on custom scale factors. Its still in beta, be sure to notify any issues/suggestions you come across to the developer.

The main differenece is that bidirectional relationship provides navigational access in both directions, so that you can access the other side without explicit queries. Also it allows you to apply cascading options to both directions.

Note that navigational access is not always good, especially for "one-to-very-many" and "many-to-very-many" relationships. Imagine a Group that contains thousands of Users:

• How would you access them? With so many Users, you usually need to apply some filtering and/or pagination, so that you need to execute a query anyway (unless you use collection filtering, which looks like a hack for me). Some developers may tend to apply filtering in memory in such cases, which is obviously not good for performance. Note that having such a relationship can encourage this kind of developers to use it without considering performance implications.

• How would you add new Users to the Group? Fortunately, Hibernate looks at the owning side of relationship when persisting it, so you can only set User.group. However, if you want to keep objects in memory consistent, you also need to add User to Group.users. But it would make Hibernate to fetch all elements of Group.users from the database!

So, I can't agree with the recommendation from the Best Practices. You need to design bidirectional relationships carefully, considering use cases (do you need navigational access in both directions?) and possible performance implications.

If you are using tortoise git.

please follow the below steps.

1. Checkout BranchB
2. Open project folder, go to TortoiseGit --> Pull
3. In pull screen, Change the remote branch "BranchA" and click ok.
4. Then right click again, go to TortoiseGit --> Push.

Now your changes moved from BranchA to BranchB

Check for syntax errors in the php.ini file, specially before the Date paramaters, that prevent the file from being parsed correctly.

For single line comment just use // and for multiline comments use /* your code here */

If you "git pull" and it says "Already up-to-date.", and still get this error, it might be because one of your other branches isn't up to date. Try switching to another branch and making sure that one is also up-to-date before trying to "git push" again:

Switch to branch "foo" and update it:

$ git checkout foo
$ git pull

You can see the branches you've got by issuing command:

$ git branch

None of the answers here worked for me. This was what worked.

Test_y = np.nan_to_num(Test_y)

It replaces the infinity values with high finite values and the nan values with numbers

Basically, what is happening is that your user is either closing the browser tab, or is navigating away to a different page, before communication was complete. Your webserver (Jetty) generates this exception because it is unable to send the remaining bytes.

org.eclipse.jetty.io.EofException: null
! at org.eclipse.jetty.http.HttpGenerator.flushBuffer(HttpGenerator.java:914)
! at org.eclipse.jetty.http.HttpGenerator.complete(HttpGenerator.java:798)
! at org.eclipse.jetty.server.AbstractHttpConnection.completeResponse(AbstractHttpConnection.java:642)
! 

This is not an error on your application logic side. This is simply due to user behavior. There is nothing wrong in your code per se.

There are two things you may be able to do:

1. Ignore this specific exception so that you don't log it.
2. Make your code more efficient/packed so that it transmits less data. (Not always an option!)

Here is a updated version of the code provided by @theprtk. It is a cleaned up a little to show the generalized version whilst having an example.

Note: I'd add this as a comment to his post but I don't have enough reputation yet

I managed to render the following SELECT with SQLAlchemy on both layers.

SELECT count(*) AS count_1
FROM "table"

Usage from the SQL Expression layer

from sqlalchemy import select, func, Integer, Table, Column, MetaData

metadata = MetaData()

table = Table("table", metadata,
              Column('primary_key', Integer),
              Column('other_column', Integer)  # just to illustrate
             )   

print select([func.count()]).select_from(table)

Usage from the ORM layer

You just subclass Query (you have probably anyway) and provide a specialized count() method, like this one.

from sqlalchemy.sql.expression import func

class BaseQuery(Query):
    def count_star(self):
        count_query = (self.statement.with_only_columns([func.count()])
                       .order_by(None))
        return self.session.execute(count_query).scalar()

Please note that order_by(None) resets the ordering of the query, which is irrelevant to the counting.

Using this method you can have a count(*) on any ORM Query, that will honor all the filter andjoin conditions already specified.

try it ! also can calculate NA's data!

df <- data.frame(a1=1:10, a2=11:20)

df %>% summarise_each(funs( mean( .,na.rm = TRUE)))


# a1   a2
# 5.5 15.5

You can use the code below:

document.body.addEventListener('click', function (evt) {
    if (evt.target.className === 'databox') {
        alert(this)
    }
}, false);

If you really need to hide the value that the "real" iterator returns (for example because you want to use your key-iterator with standard algorithms, so that they operate on the keys instead of the pairs), then take a look at Boost's transform_iterator.

[Tip: when looking at Boost documentation for a new class, read the "examples" at the end first. You then have a sporting chance of figuring out what on earth the rest of it is talking about :-)]

Try this code:

final File f = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());

replace 'MyClass' with your class containing the main method.

Alternatively you can also use

System.getProperty("java.class.path")

Above mentioned System property provides

Path used to find directories and JAR archives containing class files. Elements of the class path are separated by a platform-specific character specified in the path.separator property.

Here is the approach that worked for me (and I don't see it being used above)

$ find /path/to/the/folder -name *.* -mmin +59 -delete > /dev/null

deleting all the files older than 59 minutes while leaving the folders intact.

As of API version 3.26.10, you can set the marker label with more than one characters. The restriction is lifted.

Try it, it works!

Moreover, using a MarkerLabel object instead of just a string, you can set a number of properties for the appearance, and if using a custom Icon you can set the labelOrigin property to reposition the label.

From JQuery Documentation

The jqXHR objects returned by $.ajax() as of jQuery 1.5 implement the Promise interface, giving them all the properties, methods, and behavior of a Promise (see Deferred object for more information). These methods take one or more function arguments that are called when the $.ajax() request terminates. This allows you to assign multiple callbacks on a single request, and even to assign callbacks after the request may have completed. (If the request is already complete, the callback is fired immediately.) Available Promise methods of the jqXHR object include:

jqXHR.done(function( data, textStatus, jqXHR ) {});

An alternative construct to the success callback option, refer to deferred.done() for implementation details.

jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {});

An alternative construct to the error callback option, the .fail() method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.

jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { }); 

(added in jQuery 1.6) An alternative construct to the complete callback option, the .always() method replaces the deprecated .complete() method.

In response to a successful request, the function's arguments are the same as those of .done(): data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail(): the jqXHR object, textStatus, and errorThrown. Refer to deferred.always() for implementation details.

jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {});

Incorporates the functionality of the .done() and .fail() methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then() for implementation details.

Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

Add &wmode=transparent to the url and you're done, tested.

I use that technique in my own wordpress plugin YouTube shortcode

As already pointed out Integer.toString() or String.valueOf() are the way to go. I was curious and did a quick benchmark:

Integer.toString(i) and String.valueOf(i) are basically identical in performance, with Integer.toString(i) being a tiny bit faster. However i + "" is 1.7 times slower.

import java.util.Random;

public class Test {

    public static void main(String[] args) {
        long concat = 0;
        long valueOf = 0;
        long toString = 0;
        
        int iterations = 10000;
        int runs = 1000;
        for(int i = 0; i < runs; i++) {
            concat += concat(iterations);
            valueOf += valueOf(iterations);
            toString += to_String(iterations);
        }
        
        System.out.println("concat: " + concat/runs);
        System.out.println("valueOf: " + valueOf/runs);
        System.out.println("toString: " + toString/runs);
    }
    
    public static long concat(int iterations) {
        Random r = new Random(0);
        long start = System.nanoTime();
        for(int i = 0; i < iterations; i++) {
            String s = r.nextInt() + "";
        }
        return System.nanoTime() - start;
    }
    
    public static long valueOf(int iterations) {
        Random r = new Random(0);
        long start = System.nanoTime();
        for(int i = 0; i < iterations; i++) {
            String s = String.valueOf(r.nextInt());
        }
        return System.nanoTime() - start;
    }
    
    public static long to_String(int iterations) {
        Random r = new Random(0);
        long start = System.nanoTime();
        for(int i = 0; i < iterations; i++) {
            String s = Integer.toString(r.nextInt());
        }
        return System.nanoTime() - start;
    }
}

Output:

concat: 1004109
valueOf: 590978
toString: 587236

this is a mysql function example. I hope it helps. (I have not tested it yet, but should work)

My issue was the Eclipse Marketplace client needed updating.

After trying Fredriks solution of

Go to Window -> Preferences -> Install/update: Available Software sites. Then remove and add the indigo site. Just remember to copy the adress so you can add it again.

The Marketplace client wouldn't load. But I could access it via a browser. So, I went to the Help -> Eclipse Marketplace it loaded fine

Clicked on Installed and found the Eclipse Marketplace Client and it had so i clicked it it updated and then when I did the standard update everything worked.

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

You can put custom image in radiobutton like normal button. for that create one XML file in drawable folder e.g

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/sub_screens_aus_hl" 
    android:state_pressed="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_checked="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_focused="true" />
<item android:drawable="@drawable/sub_screens_aus_dis" />  
</selector> 

Here you can use 3 different images for radiobutton

and use this file to RadioButton like:

android:button="@drawable/aus"
android:layout_height="120dp"
android:layout_width="wrap_content" 

You can use /start /max [your batch] it will fill the screen with the program it oppose to /min

 string AssemblyID = Assembly.GetEntryAssembly().GetCustomAttribute<GuidAttribute>().Value;

or, VB.NET:

  Dim AssemblyID As String = Assembly.GetEntryAssembly.GetCustomAttribute(Of GuidAttribute).Value

Here's some code with a dummy geom_blank layer,

range_act <- range(range(results$act), range(results$pred))

d <- reshape2::melt(results, id.vars = "pred")

dummy <- data.frame(pred = range_act, value = range_act,
                    variable = "act", stringsAsFactors=FALSE)

ggplot(d, aes(x = pred, y = value)) +
  facet_wrap(~variable, scales = "free") +
  geom_point(size = 2.5) + 
  geom_blank(data=dummy) + 
  theme_bw()

You could do it as follows - with validation just to ensure that the datepicker is bound to the element.

var dt;

if ($("div#someID").is('.hasDatepicker')) {
    dt = $("div#someID").datepicker('getDate');
}

Could you try this out?

=IIF((Fields!OpeningStock.Value=0) AND (Fields!GrossDispatched.Value=0) AND 
(Fields!TransferOutToMW.Value=0) AND (Fields!TransferOutToDW.Value=0) AND 
(Fields!TransferOutToOW.Value=0) AND (Fields!NetDispatched.Value=0) AND (Fields!QtySold.Value=0) 
AND (Fields!StockAdjustment.Value=0) AND (Fields!ClosingStock.Value=0),True,False)

Note: Setting Hidden to False will make the row visible

Use Reader.read(). A return value of -1 means end of stream; else, cast to char.

This code reads character data from a list of file arguments:

public class CharacterHandler {
    //Java 7 source level
    public static void main(String[] args) throws IOException {
        // replace this with a known encoding if possible
        Charset encoding = Charset.defaultCharset();
        for (String filename : args) {
            File file = new File(filename);
            handleFile(file, encoding);
        }
    }

    private static void handleFile(File file, Charset encoding)
            throws IOException {
        try (InputStream in = new FileInputStream(file);
             Reader reader = new InputStreamReader(in, encoding);
             // buffer for efficiency
             Reader buffer = new BufferedReader(reader)) {
            handleCharacters(buffer);
        }
    }

    private static void handleCharacters(Reader reader)
            throws IOException {
        int r;
        while ((r = reader.read()) != -1) {
            char ch = (char) r;
            System.out.println("Do something with " + ch);
        }
    }
}

The bad thing about the above code is that it uses the system's default character set. Wherever possible, prefer a known encoding (ideally, a Unicode encoding if you have a choice). See the Charset class for more. (If you feel masochistic, you can read this guide to character encoding.)

(One thing you might want to look out for are supplementary Unicode characters - those that require two char values to store. See the Character class for more details; this is an edge case that probably won't apply to homework.)

Solution: call the update method to set new values ??:

var barChartData = {
    labels: ["January", "February", "March"],
    datasets: [
        {
            label: "My First dataset",

            strokeColor: "rgba(220,220,220,0.8)", 
            highlightFill: "rgba(220,220,220,0.75)",
            highlightStroke: "rgba(220,220,220,1)",
            data: [20, 59, 80]
        }
    ]
};

window.onload = function(){
    var ctx = document.getElementById("mycanvas").getContext("2d");
    window.myObjBar = new Chart(ctx).Bar(barChartData, {
          responsive : true
    });

    //nuevos colores
    myObjBar.datasets[0].bars[0].fillColor = "green"; //bar 1

To keep your Docker images small, don't install unnecessary editors. You can edit the files over SSH from the Docker host to the container:

vim scp://remoteuser@containerip//path/to/document

You can use date_diff to calculate the difference between two dates:

$date1 = date_create("2013-03-15");
$date2 = date_create("2013-12-12");
$diff =  date_diff($date1 , $date2);
echo  $diff->format("%R%a days");

You use an anchor and a hash. For example:

Target of the Link:

 <a name="name_of_target">Content</a>

Link to the Target:

 <a href="#name_of_target">Link Text</a>

Or, if linking from a different page:

 <a href="http://path/to/page/#name_of_target">Link Text</a>

I had a similar problem and this scale worked for me like a charm:

breaks = 10**(1:10)
scale_y_log10(breaks = breaks, labels = comma(breaks))

as you want the intermediate levels, too (10^3.5), you need to tweak the formatting:

breaks = 10**(1:10 * 0.5)
m <- ggplot(diamonds, aes(y = price, x = color)) + geom_boxplot()
m + scale_y_log10(breaks = breaks, labels = comma(breaks, digits = 1))

After executing::

Yes, it is a hash mapping or hash table. You can read a description of python's dict implementation, as written by Tim Peters, here.

That's why you can't use something 'not hashable' as a dict key, like a list:

>>> a = {}
>>> b = ['some', 'list']
>>> hash(b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable
>>> a[b] = 'some'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable

You can read more about hash tables or check how it has been implemented in python and why it is implemented that way.

Whether to open the URL in a new tab or a new window, is actually controlled by the user's browser preferences. There is no way to override it in JavaScript.

window.open() behaves differently depending on how it is being used. If it is called as a direct result of a user action, let us say a button click, it should work fine and open a new tab (or window):

const button = document.querySelector('#openTab');

// add click event listener
button.addEventListener('click', () => {
    // open a new tab
    const tab = window.open('https://attacomsian.com', '_blank');
});

However, if you try to open a new tab from an AJAX request callback, the browser will block it as it was not a direct user action.

To bypass the popup blocker and open a new tab from a callback, here is a little hack:

const button = document.querySelector('#openTab');

// add click event listener
button.addEventListener('click', () => {

    // open an empty window
    const tab = window.open('about:blank');

    // make an API call
    fetch('/api/validate')
        .then(res => res.json())
        .then(json => {

            // TODO: do something with JSON response

            // update the actual URL
            tab.location = 'https://attacomsian.com';
            tab.focus();
        })
        .catch(err => {
            // close the empty window
            tab.close();
        });
});

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

For a pure numpy implementation of Cartesian product of 1D arrays (or flat python lists), just use meshgrid(), roll the axes with transpose(), and reshape to the desired ouput:

 def cartprod(*arrays):
     N = len(arrays)
     return transpose(meshgrid(*arrays, indexing='ij'), 
                      roll(arange(N + 1), -1)).reshape(-1, N)

Note this has the convention of last axis changing fastest ("C style" or "row-major").

If you want to change the first axis fastest ("FORTRAN style" or "column-major"), just change the order parameter of reshape() like this: reshape((-1, N), order='F')

Okay so what helped me was iterating backwards. I was trying to remove an entry from a list but iterating upwards and it screwed up the loop because the entry didn't exist anymore:

for (int x = myList.Count - 1; x > -1; x--)
{
    myList.RemoveAt(x);
}

1220227200 corresponds to Jan 15 1980 (and indeed new Date(1220227200).toString() returns "Thu Jan 15 03:57:07 CET 1970"). If you pass a long value to a date, that is before 01/01/1970 it will in fact return a date of 01/01/1970. Make sure that your values are not in this situation (lower than 82800000).

for frequency distribution of a variable with excessive values you can collapse down the values in classes,

Here I excessive values for employrate variable, and there's no meaning of it's frequency distribution with direct values_count(normalize=True)

frequency distribution with values_count(normalize=True) with no classification,length of result here is 139 (seems meaningless as a frequency distribution):

putting classification we put all values with a certain range ie.

after classification we have a clear frequency distribution. here we can easily see, that 37.64% of countries have employ rate between 51-60% and 11.79% of countries have employ rate between 71-80%

yes the best way to see what is modified is to save in file like that:

git stash show -p stash@{0} > stash.txt

In Laravel 5.1, you specify the connection:

$users = DB::connection('foo')->select(...);

Default, Laravel uses the default connection. It is simple, isn't it?

def dt2ts(dt, utc=False):
    if utc:
        return calendar.timegm(dt.timetuple())
    if dt.tzinfo is None:
        return int(time.mktime(dt.timetuple()))
    utc_dt = dt.astimezone(tz.tzutc()).timetuple()
    return calendar.timegm(utc_dt)

If you want UTC timestamp :time.mktime just for local dt .Use calendar.timegm is safe but dt must the utc zone so change the zone to utc. If dt in UTC just use calendar.timegm.

Turns out you don't have to do much at all.

I wanted to run a database on a large USB HDD drive. Drives larger than 2 TB are GPT partitioned! Here is a bug report with a solution:

Since some years some devices support <input type="date"> but others don't, so one needs to be careful. Here are some observations from 2012, which still might be valid today:

• One can detect if type="date" is supported by setting that attribute and then reading back its value. Browsers/devices that don't support it will ignore setting the type to date and return text when reading back that attribute. Alternatively, Modernizr can be used for detection. Beware that it's not enough to check for some Android version; like the Samsung Galaxy S2 on Android 4.0.3 does support type="date", but the Google/Samsung Nexus S on the more recent Android 4.0.4 does not.

• When presetting the date for the native date picker, be sure to use a format the device recognizes. When not doing that, devices might silently reject it, leaving one with an empty input field when trying to show an existing value. Like using the date picker on a Galaxy S2 running Android 4.0.3 might itself set the <input> to 2012-6-1 for June 1st. However, when setting the value from JavaScript, it needs leading zeroes: 2012-06-01.

• When using things like Cordova (PhoneGap) to display the native date picker on devices that don't support type="date":

  • Be sure to properly detect built-in support. Like in 2012 on the Galaxy S2 running Android 4.0.3, erroneously also using the Cordova Android plugin would result in showing the date picker twice in a row: once again after clicking "set" in its first occurrence.

  • When there's multiple inputs on the same page, some devices show "previous" and "next" to get into another form field. On iOS 4, this does not trigger the onclick handler and hence gives the user a regular input. Using onfocus to trigger the plugin seemed to work better.

  • On iOS 4, using onclick or onfocus to trigger the 2012 iOS plugin first made the regular keyboard show, after which the date picker was placed on top of that. Next, after using the date picker, one still needed to close the regular keyboard. Using $(this).blur() to remove focus before the date picker was shown helped for iOS 4 and did not affect other devices I tested. But it introduced some quick flashing of the keyboard on iOS, and things could be even more confusing on first usage as then the date picker was slower. One could fully disable the regular keyboard by making the input readonly if one were using the plugin, but that disabled the "previous" and "next" buttons when typing in other inputs on the same screen. It also seems the iOS 4 plugin did not make the native date picker show "cancel" or "clear".

  • On an iOS 4 iPad (simulator), in 2012 the Cordova plugin did not seem to render correctly, basically not giving the user any option to enter or change a date. (Maybe iOS 4 doesn't render its native date picker nicely on top of a web view, or maybe my web view's CSS styling has some effect, and surely this might be different on a real device: please comment or edit!)

  • Though, again in 2012, the Android date picker plugin tried to use the same JavaScript API as the iOS plugin, and its example used allowOldDates, the Android version actually did not support that. Also, it returned the new date as 2012/7/2 while the iOS version returned Mon Jul 02 2012 00:00:00 GMT+0200 (CEST).

• Even when <input type="date"> is supported, things might look messy:

  • iOS 5 nicely displays 2012-06-01 in a localized format, like 1 Jun. 2012 or June 1, 2012 (and even updates that immediately while still operating the date picker). However, the Galaxy S2 running Android 4.0.3 shows the ugly 2012-6-1 or 2012-06-01, no matter which locale is used.

  • iOS 5 on an iPad (simulator) does not hide the keyboard when that is already visible when touching the date input, or when using "previous" or "next" in another input. It then simultaneously shows the date picker below the input and the keyboard at the bottom, and seems to allow any input from both. However, though it does change the visible value, the keyboard input is actually ignored. (Shown when reading back the value, or when invoking the date picker again.) When the keyboard was not yet shown, then touching the date input only shows the date picker, not the keyboard. (This might be different on a real device, please comment or edit!)

  • Devices might show a cursor in the input field, and a long press might trigger the clipboard options, possibly showing the regular keyboard too. When clicking, some devices might even show the regular keyboard for a split second, before changing to show the date picker.

If you can I would reconsider doing this: the default action of pressing <Enter> while in a form submits the form and anything you do to change this default action / expected behaviour could cause some usability issues with the site.

There are some good answers already. I'll focus mainly on what I think they lack - an explanation of the "cons" with the copy-and-swap idiom....

What is the copy-and-swap idiom?

A way of implementing the assignment operator in terms of a swap function:

X& operator=(X rhs)
{
    swap(rhs);
    return *this;
}

The fundamental idea is that:

• the most error-prone part of assigning to an object is ensuring any resources the new state needs are acquired (e.g. memory, descriptors)

• that acquisition can be attempted before modifying the current state of the object (i.e. *this) if a copy of the new value is made, which is why rhs is accepted by value (i.e. copied) rather than by reference

• swapping the state of the local copy rhs and *this is usually relatively easy to do without potential failure/exceptions, given the local copy doesn't need any particular state afterwards (just needs state fit for the destructor to run, much as for an object being moved from in >= C++11)

When should it be used? (Which problems does it solve [/create]?)

• When you want the assigned-to objected unaffected by an assignment that throws an exception, assuming you have or can write a swap with strong exception guarantee, and ideally one that can't fail/throw..†

• When you want a clean, easy to understand, robust way to define the assignment operator in terms of (simpler) copy constructor, swap and destructor functions.

  • Self-assignment done as a copy-and-swap avoids oft-overlooked edge cases.‡

• When any performance penalty or momentarily higher resource usage created by having an extra temporary object during the assignment is not important to your application. ?

† swap throwing: it's generally possible to reliably swap data members that the objects track by pointer, but non-pointer data members that don't have a throw-free swap, or for which swapping has to be implemented as X tmp = lhs; lhs = rhs; rhs = tmp; and copy-construction or assignment may throw, still have the potential to fail leaving some data members swapped and others not. This potential applies even to C++03 std::string's as James comments on another answer:

@wilhelmtell: In C++03, there is no mention of exceptions potentially thrown by std::string::swap (which is called by std::swap). In C++0x, std::string::swap is noexcept and must not throw exceptions. – James McNellis Dec 22 '10 at 15:24

‡ assignment operator implementation that seems sane when assigning from a distinct object can easily fail for self-assignment. While it might seem unimaginable that client code would even attempt self-assignment, it can happen relatively easily during algo operations on containers, with x = f(x); code where f is (perhaps only for some #ifdef branches) a macro ala #define f(x) x or a function returning a reference to x, or even (likely inefficient but concise) code like x = c1 ? x * 2 : c2 ? x / 2 : x;). For example:

struct X
{
    T* p_;
    size_t size_;
    X& operator=(const X& rhs)
    {
        delete[] p_;  // OUCH!
        p_ = new T[size_ = rhs.size_];
        std::copy(p_, rhs.p_, rhs.p_ + rhs.size_);
    }
    ...
};

On self-assignment, the above code delete's x.p_;, points p_ at a newly allocated heap region, then attempts to read the uninitialised data therein (Undefined Behaviour), if that doesn't do anything too weird, copy attempts a self-assignment to every just-destructed 'T'!

? The copy-and-swap idiom can introduce inefficiencies or limitations due to the use of an extra temporary (when the operator's parameter is copy-constructed):

struct Client
{
    IP_Address ip_address_;
    int socket_;
    X(const X& rhs)
      : ip_address_(rhs.ip_address_), socket_(connect(rhs.ip_address_))
    { }
};

Here, a hand-written Client::operator= might check if *this is already connected to the same server as rhs (perhaps sending a "reset" code if useful), whereas the copy-and-swap approach would invoke the copy-constructor which would likely be written to open a distinct socket connection then close the original one. Not only could that mean a remote network interaction instead of a simple in-process variable copy, it could run afoul of client or server limits on socket resources or connections. (Of course this class has a pretty horrid interface, but that's another matter ;-P).

All executable files from Visual Studio should be located in the debug folder of your project, e.g:

Visual Studio Directory: c:\users\me\documents\visual studio

Then the project which was called 'hello world' would be in the directory:

c:\users\me\documents\visual studio\hello world

And your exe would be located in:

c:\users\me\documents\visual studio\hello world\Debug\hello world.exe

Note the exe being named the same as the project.

Otherwise, you could publish it to a specified folder of your choice which comes with an installation, which would be good if you wanted to distribute it quickly

EDIT:

Everytime you build your project in VS, the exe is updated with the new one according to the code (as long as it builds without errors). When you publish it, you can choose the location, aswell as other factors, and the setup exe will be in that location, aswell as some manifest files and other files about the project.

EntityManager.persist() makes an entity persistent whereas EntityManager.flush() actually runs the query on your database.

So, when you call EntityManager.flush(), queries for inserting/updating/deleting associated entities are executed in the database. Any constraint failures (column width, data types, foreign key) will be known at this time.

The concrete behaviour depends on whether flush-mode is AUTO or COMMIT.

For importing database file in .sql.gz format, remove definer and import using below command

zcat path_to_db_to_import.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db_name

1. Earlier, export database in .sql.gz format using below command.

   mysqldump -u user -p old_db | gzip -9 > path_to_db_exported.sql.gz;

2. Import that exported database and removing definer using below command,

   zcat path_to_db_exported.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db

The Predicate will always return a boolean, by definition.

Predicate<T> is basically identical to Func<T,bool>.

Predicates are very useful in programming. They are often used to allow you to provide logic at runtime, that can be as simple or as complicated as necessary.

For example, WPF uses a Predicate<T> as input for Filtering of a ListView's ICollectionView. This lets you write logic that can return a boolean determining whether a specific element should be included in the final view. The logic can be very simple (just return a boolean on the object) or very complex, all up to you.

use blow code for compute height + scroll

var dif = document.documentElement.scrollHeight - document.documentElement.clientHeight;

var height = dif + document.documentElement.scrollHeight +"px";

To force a reload of the php.ini you should restart apache.

Try sudo service apache2 restart from the command line. Or sudo /etc/init.d/apache2 restart

One thing to note, sed cannot write files on its own as the sole purpose of sed is to act as an editor on the "stream" (ie pipelines of stdin, stdout, stderr, and other >&n buffers, sockets and the like). With this in mind you can use another command tee to write the output back to the file. Another option is to create a patch from piping the content into diff.

Tee method

sed '/regex/' <file> | tee <file>

Patch method

sed '/regex/' <file> | diff -p <file> /dev/stdin | patch

UPDATE:

Also, note that patch will get the file to change from line 1 of the diff output:

Patch does not need to know which file to access as this is found in the first line of the output from diff:

$ echo foobar | tee fubar

$ sed 's/oo/u/' fubar | diff -p fubar /dev/stdin
*** fubar   2014-03-15 18:06:09.000000000 -0500

use maven dependency

<dependency> 
  <groupId>org.apache.commons</groupId>

or download commons-io.1.3.2.jar to your lib folder

Use like this for nested objects,

NSSortDescriptor * sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"lastRoute.to.lastname" ascending:YES selector:@selector(caseInsensitiveCompare:)];
NSMutableArray *sortedPackages = [[NSMutableArray alloc]initWithArray:[packages sortedArrayUsingDescriptors:@[sortDescriptor]]];

lastRoute is one object and that object holds the to object, that to object hold the lastname string values.

JSP/Servlet 2.4 (I think that's the version number) doesn't support method calls in EL and only support properties. The latest servlet containers do support method calls (ie Tomcat 7).

I'm the author of HPN-SSH and I was asked by a commenter here to weigh in. I'd like to start with a couple of background items. First off, it's important to keep in mind that SSHv2 is a multiplexed protocol - multiple channels over a single TCP connection. As such, the SSH channels are essentially unaware of the underlying flow control algorithm used by TCP. This means that SSHv2 has to implement its own flow control algorithm. The most common implementation basically reimplements sliding windows. The means that you have the SSH sliding window riding on top of the TCP sliding window. The end results is that the effective size of the receive buffer is the minimum of the receive buffers of the two sliding windows. Stock OpenSSH has a maximum receive buffer size of 2MB but this really ends up being closer to ~1.2MB. Most modern OSes have a buffer that can grow (using auto-tuning receive buffers) up to an effective size of 4MB. Why does this matter? If the receive buffer size is less than the bandwidth delay product (BDP) then you will never be able to fully fill the pipe regardless of how fast your system is.

This is complicated by the fact that SFTP adds another layer of flow control onto of the TCP and SSH flow controls. SFTP uses a concept of outstanding messages. Each message may be a command, a result of a command, or bulk data flow. The outstanding messages may be up to a specific datagram size. So you end up with what you might as well think of as yet another receive buffer. The size of this receive buffer is datagram size * maximum outstanding messages (both of which may be set on the command line). The default is 32k * 64 (2MB). So when using SFTP you have to make sure that the TCP receive buffer, the SSH receive buffer, and the SFTP receive buffer are all of sufficient size (without being too large or you can have over buffering problems in interactive sessions).

HPN-SSH directly addresses the SSH buffer problem by having a maximum buffer size of around 16MB. More importantly, the buffer dynamically grows to the proper size by polling the proc entry for the TCP connection's buffer size (basically poking a hole between layers 3 and 4). This avoids overbuffering in almost all situations. In SFTP we raise the maximum number of outstanding requests to 256. At least we should be doing that - it looks like that change didn't propagate as expected to the 6.3 patch set (though it is in 6.2. I'll fix that soon). There isn't a 6.4 version because 6.3 patches cleanly against 6.4 (which is a 1 line security fix from 6.3). You can get the patch set from sourceforge.

I know this sounds odd but right sizing the buffers was the single most important change in terms of performance. In spite of what many people think the encryption is not the real source of poor performance in most cases. You can prove this to yourself by transferring data to sources that are increasingly far away (in terms of RTT). You'll notice that the longer the RTT the lower the throughput. That clearly indicates that this is an RTT dependent performance problem.

Anyway, with this change I started seeing improvements of up to 2 orders of magnitude. If you understand TCP you'll understand why this made such a difference. It's not about the size of the datagram or the number of packets or anything like that. It's entire because in order to make efficient use of the network path you must have a receive buffer equal to the amount of data that can be in transit between the two hosts. This also means that you may not see any improvement whatsoever if the path isn't sufficiently fast and long enough. If the BDP is less than 1.2MB HPN-SSH may be of no value to you.

The parallelized AES-CTR cipher is a performance boost on systems with multiple cores if you need to have full encryption end to end. Usually I suggest people (or have control over both the server and client) to use the NONE cipher switch (encrypted authentication, bulk data passed in clear) as most data isn't all that sensitive. However, this only works in non-interactive sessions like SCP. It doesn't work in SFTP.

There are some other performance improvements as well but nothing as important as the right sizing of the buffers and the encryption work. When I get some free time I'll probably pipeline the HMAC process (currently the biggest drag on performance) and do some more minor optimization work.

So if HPN-SSH is so awesome why hasn't OpenSSH adopted it? That's a long story and people who know the OpenBSD team probably already know the answer. I understand many of their reasons - it's a big patch which would require additional work on their end (and they are a small team), they don't care as much about performance as security (though there is no security implications to HPN-SSH), etc etc etc. However, even though OpenSSH doesn't use HPN-SSH Facebook does. So do Google, Yahoo, Apple, most ever large research data center, NASA, NOAA, the government, the military, and most financial institutions. It's pretty well vetted at this point.

If anyone has any questions feel free to ask but I may not be keeping up to date on this forum. You can always send me mail via the HPN-SSH email address (google it).

This should make your TextView bold, underlined and italic at the same time.

strings.xml

<resources>
    <string name="register"><u><b><i>Copyright</i></b></u></string>
</resources>

To set this String to your TextView, do this in your main.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:text="@string/register" />

or In JAVA,

TextView textView = new TextView(this);
textView.setText(R.string.register);

Sometimes the above approach will not be helpful when you might have to use Dynamic Text. So in that case SpannableString comes into action.

String tempString="Copyright";
TextView text=(TextView)findViewById(R.id.text);
SpannableString spanString = new SpannableString(tempString);
spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
spanString.setSpan(new StyleSpan(Typeface.BOLD), 0, spanString.length(), 0);
spanString.setSpan(new StyleSpan(Typeface.ITALIC), 0, spanString.length(), 0);
text.setText(spanString);

OUTPUT

You need to add a reference to your class library from your project. Right click on the references folder and click add reference. You can either browse for the DLL or, if your class libaray is a project in your solution you can add a project reference.

package: take the compiled code and package it in its distributable format, such as a JAR.

install: install the package into the local repository, for use as a dependency in other projects locally

So the answer to your question is, it depends on whether you want it in installed into your local repo. Install will also run package because it's higher up in the goal phase stack.

Use

• android:singleLine="true"
• android:maxLines="1"
• app:layout_constrainedWidth="true"

It's how my full TextView looks:

    <TextView
    android:id="@+id/message_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="5dp"
    android:maxLines="1"
    android:singleLine="true"
    android:text="NAME PLACEHOLDER MORE Text"
    android:textColor="@android:color/black"
    android:textSize="16sp"

    android:textStyle="bold"
    app:layout_constrainedWidth="true"
    app:layout_constraintEnd_toStartOf="@id/message_check_sign"
    app:layout_constraintHorizontal_bias="0"
    app:layout_constraintStart_toEndOf="@id/img_chat_contact"
    app:layout_constraintTop_toTopOf="@id/img_chat_contact" />

As an addition to @ANisus' answer...

below is some information from the "Go in action" book, which I think is worth mentioning:

Difference between nil & empty slices

If we think of a slice like this:

[pointer] [length] [capacity]

then:

nil slice:   [nil][0][0]
empty slice: [addr][0][0] // points to an address

nil slice

They’re useful when you want to represent a slice that doesn’t exist, such as when an exception occurs in a function that returns a slice.

// Create a nil slice of integers.
var slice []int

empty slice

Empty slices are useful when you want to represent an empty collection, such as when a database query returns zero results.

// Use make to create an empty slice of integers.
slice := make([]int, 0)

// Use a slice literal to create an empty slice of integers.
slice := []int{}

Regardless of whether you’re using a nil slice or an empty slice, the built-in functions append, len, and cap work the same.

Go playground example:

package main

import (
    "fmt"
)

func main() {

    var nil_slice []int
    var empty_slice = []int{}

    fmt.Println(nil_slice == nil, len(nil_slice), cap(nil_slice))
    fmt.Println(empty_slice == nil, len(empty_slice), cap(empty_slice))

}

prints:

true 0 0
false 0 0

I assume you're looking for "1.4 MB" instead of "1468006 bytes"?

I don't think there is a built-in way to do that in .NET. You'll need to just figure out which unit is appropriate, and format it.

Edit: Here's some sample code to do just that:

http://www.codeproject.com/KB/cpp/formatsize.aspx

I created small utility which tries to allocate as much memory as possible to crash and it records when memory warnings and crash happened. This helps to find out what's the memory budget for any iOS device.

I had to run this for a column introduced in the later stages of a product, on 10+ tables. So wrote this quick untidy script to generate the alter command for all 'relevant' tables.

SET @NeighboringColumn = '<YOUR COLUMN SHOULD COME AFTER THIS COLUMN>';

SELECT CONCAT("ALTER TABLE `",t.TABLE_NAME,"` CHANGE COLUMN `",COLUMN_NAME,"` 
`",COLUMN_NAME,"` ", c.DATA_TYPE, CASE WHEN c.CHARACTER_MAXIMUM_LENGTH IS NOT 
NULL THEN CONCAT("(", c.CHARACTER_MAXIMUM_LENGTH, ")") ELSE "" END ,"  AFTER 
`",@NeighboringColumn,"`;")
FROM information_schema.COLUMNS c, information_schema.TABLES t
WHERE c.TABLE_SCHEMA = '<YOUR SCHEMA NAME>'
AND c.COLUMN_NAME = '<COLUMN TO MOVE>'
AND c.TABLE_SCHEMA = t.TABLE_SCHEMA
AND c.TABLE_NAME = t.TABLE_NAME
AND t.TABLE_TYPE = 'BASE TABLE'
AND @NeighboringColumn IN (SELECT COLUMN_NAME 
    FROM information_schema.COLUMNS c2 
    WHERE c2.TABLE_NAME = t.TABLE_NAME);

For those that want to continue using version ^3.0.1 be aware of the changes to how you use the MongoClient.connect() method. The callback doesn't return db instead it returns client, against which there is a function called db(dbname) that you must invoke to get the db instance you are looking for.

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');

// Connection URL
const url = 'mongodb://localhost:27017';

// Database Name
const dbName = 'myproject';

// Use connect method to connect to the server
MongoClient.connect(url, function(err, client) {
  assert.equal(null, err);
  console.log("Connected successfully to server");

  const db = client.db(dbName);

  client.close();
});

var specialChars = "<>@!#$%^&*()_+[]{}?:;|'\"\\,./~`-="
var check = function(string){
    for(i = 0; i < specialChars.length;i++){
        if(string.indexOf(specialChars[i]) > -1){
            return true
        }
    }
    return false;
}

if(check($('#Search').val()) == false){
    // Code that needs to execute when none of the above is in the string
}else{
    alert('Your search string contains illegal characters.');
}

The ist and 2nd answer are good but if anybody is looking for having a script or If you want dynamic i.e (db/username/password in variable) then here:

#!/bin/bash



DB="mydb"
USER="user1"
PASS="pass_bla"

mysql -uroot -prootpassword -e "CREATE DATABASE $DB CHARACTER SET utf8 COLLATE utf8_general_ci";
mysql -uroot -prootpassword -e "CREATE USER $USER@'127.0.0.1' IDENTIFIED BY '$PASS'";
mysql -uroot -prootpassword -e "GRANT SELECT, INSERT, UPDATE ON $DB.* TO '$USER'@'127.0.0.1'";

i had the same problem in visual studio 2019 and it resolved by searching in the searchbar inside visual studio: manage NuGet packages > oracle.ManagedDataAccess (first result) install it. and then it should works!

jQuery is just wrapping the standard resize DOM event, eg.

window.onresize = function(event) {
    ...
};

jQuery may do some work to ensure that the resize event gets fired consistently in all browsers, but I'm not sure if any of the browsers differ, but I'd encourage you to test in Firefox, Safari, and IE.

Something I learned just now is that your file is not allowed to have a "." (dot) in the filename.

Templates.plainEmailBodyTemplate-en.txt --> Works!!!
Templates.plainEmailBodyTemplate.en.txt --> doesn't work via GetManifestResourceStream()

Probably because the framework gets confused over namespaces vs filename...

This will get you all the user created tables:

select * from sysobjects where xtype='U'

To get the cols:

Select * from Information_Schema.Columns Where Table_Name = 'Insert Table Name Here'

Also, I find http://www.sqlservercentral.com/ to be a pretty good db resource.

These are the vendor-prefixed properties offered by the relevant rendering engines (-webkit for Chrome, Safari; -moz for Firefox, -o for Opera, -ms for Internet Explorer). Typically they're used to implement new, or proprietary CSS features, prior to final clarification/definition by the W3.

This allows properties to be set specific to each individual browser/rendering engine in order for inconsistencies between implementations to be safely accounted for. The prefixes will, over time, be removed (at least in theory) as the unprefixed, the final version, of the property is implemented in that browser.

To that end it's usually considered good practice to specify the vendor-prefixed version first and then the non-prefixed version, in order that the non-prefixed property will override the vendor-prefixed property-settings once it's implemented; for example:

.elementClass {
    -moz-border-radius: 2em;
    -ms-border-radius: 2em;
    -o-border-radius: 2em;
    -webkit-border-radius: 2em;
    border-radius: 2em;
}

Specifically, to address the CSS in your question, the lines you quote:

-webkit-column-count: 3;
-webkit-column-gap: 10px;
-webkit-column-fill: auto;
-moz-column-count: 3;
-moz-column-gap: 10px;
-moz-column-fill: auto;

Specify the column-count, column-gap and column-fill properties for Webkit browsers and Firefox.
