As of JDK6U18 following are configurations for the Heap Size.

In the Client JVM, the default Java heap configuration has been modified to improve the performance of today's rich client applications. Initial and maximum heap sizes are larger and settings related to generational garbage collection are better tuned.

The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte. For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes. The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. This amount is at least 8 megabytes and otherwise 1/64 of physical memory up to a physical memory size of 1 gigabyte.

Source : http://www.oracle.com/technetwork/java/javase/6u18-142093.html

Increasing the heap size is not a "fix" it is a "plaster", 100% temporary. It will crash again in somewhere else. To avoid these issues, write high performance code.

1. Use local variables wherever possible.
2. Make sure you select the correct object (EX: Selection between String, StringBuffer and StringBuilder)
3. Use a good code system for your program(EX: Using static variables VS non static variables)
4. Other stuff which could work on your code.
5. Try to move with multy THREADING

Support for downloading binary files in using ajax is not great, it is very much still under development as working drafts.

Simple download method:

You can have the browser download the requested file simply by using the code below, and this is supported in all browsers, and will obviously trigger the WebApi request just the same.

$scope.downloadFile = function(downloadPath) { 
    window.open(downloadPath, '_blank', '');  
}

Ajax binary download method:

Using ajax to download the binary file can be done in some browsers and below is an implementation that will work in the latest flavours of Chrome, Internet Explorer, FireFox and Safari.

It uses an arraybuffer response type, which is then converted into a JavaScript blob, which is then either presented to save using the saveBlob method - though this is only currently present in Internet Explorer - or turned into a blob data URL which is opened by the browser, triggering the download dialog if the mime type is supported for viewing in the browser.

Internet Explorer 11 Support (Fixed)

Note: Internet Explorer 11 did not like using the msSaveBlob function if it had been aliased - perhaps a security feature, but more likely a flaw, So using var saveBlob = navigator.msSaveBlob || navigator.webkitSaveBlob ... etc. to determine the available saveBlob support caused an exception; hence why the code below now tests for navigator.msSaveBlob separately. Thanks? Microsoft

// Based on an implementation here: web.student.tuwien.ac.at/~e0427417/jsdownload.html
$scope.downloadFile = function(httpPath) {
    // Use an arraybuffer
    $http.get(httpPath, { responseType: 'arraybuffer' })
    .success( function(data, status, headers) {

        var octetStreamMime = 'application/octet-stream';
        var success = false;

        // Get the headers
        headers = headers();

        // Get the filename from the x-filename header or default to "download.bin"
        var filename = headers['x-filename'] || 'download.bin';

        // Determine the content type from the header or default to "application/octet-stream"
        var contentType = headers['content-type'] || octetStreamMime;

            window.open(httpPath, '_blank', '');
        }
    })
    .error(function(data, status) {
        console.log("Request failed with status: " + status);

        // Optionally write the error out to scope
        $scope.errorDetails = "Request failed with status: " + status;
    });
};

Usage:

var downloadPath = "/files/instructions.pdf";
$scope.downloadFile(downloadPath);

Notes:

You should modify your WebApi method to return the following headers:

• I have used the x-filename header to send the filename. This is a custom header for convenience, you could however extract the filename from the content-disposition header using regular expressions.

• You should set the content-type mime header for your response too, so the browser knows the data format.

I hope this helps.

Instead of thinking of it as 'extracting', I like to think of it as 'isolating'. Once the desired bits are isolated, you can do what you will with them.

To isolate any set of bits, apply an AND mask.

If you want the last X bits of a value, there is a simple trick that can be used.

unsigned  mask;
mask = (1 << X) - 1;
lastXbits = value & mask;

If you want to isolate a run of X bits in the middle of 'value' starting at 'startBit' ...

unsigned  mask;
mask = ((1 << X) - 1) << startBit;
isolatedXbits = value & mask;

Hope this helps.

Try this:

function children( &$parents, $parent, $selected ){
  if ($parents[$parent]){
    $list = '<ul>';
    $counter = count($parents[$parent]);
    $class = array('first');
    foreach ($parents[$parent] as $child){
      if ($child['id'] == $selected)  $class[] = 'active';
      if (!--$counter) $class[] = 'last';
      $list .= '<li class="' . implode(' ', $class) . '"><div><a href="]?id=' . $child['id'] . '" alt="' . $child['name'] . '">' . $child['name'] . '</a></div></li>';
      $class = array();
      $list .= children($parents, $child['id'], $selected);
    }
    $list .= '</ul>';
    return $list;
  }
}
$output .= children( $parents, 0, $p_industry_id);

if you want the color to change when you have simply add the :hover pseudo

div.e:hover {
    background-color:red;
}

#include<iostream>
#include<conio.h>
#include<string.h>
using namespace std;
int main()

{
    char str[80];

    int i;

    cout<<"\n enter string:";

    cin.getline(str,80);

    int n=strlen(str);

    cout<<"\n lenght is:"<<n;

    getch();

    return 0;

}

This is the program if you want to use strlen . Hope this helps!

I think Heuristic is more of a constraint used in Learning Based Model in Artificial Intelligent since the future solution states are difficult to predict.

But then my doubt after reading above answers is "How would Heuristic can be successfully applied using Stochastic Optimization Techniques? or can they function as full fledged algorithms when used with Stochastic Optimization?"

"Last but one" of a non empty row:

=OFFSET(Sheet5!$C$1,COUNTA(Sheet5!$C:$C)-2,0)

"Last" non empty row:

=OFFSET(Sheet5!$C$1,COUNTA(Sheet5!$C:$C)-1,0)

use Jackson (https://github.com/FasterXML/jackson) from http://json.org/

HashMap<String,Object> result =
       new ObjectMapper().readValue(<JSON_OBJECT>, HashMap.class);

You weren't far from the result! This does it:

awk '{NF--; print $NF}' file

This decrements the number of fields in one, so that $NF contains the former penultimate.

Test

Let's generate some numbers and print them on groups of 5:

$ seq 12 | xargs -n5
1 2 3 4 5
6 7 8 9 10
11 12

Let's print the penultimate on each line:

$ seq 12 | xargs -n5 | awk '{NF--; print $NF}'
4
9
11

I can't comment, so I will put this as a separate answer. I found a few issues with the accepted one-liner answer:

• The one-liner includes a passphrase in the key.
• The one-liner uses SHA-1 which in many browsers throws warnings in console.

Here is a simplified version that removes the passphrase, ups the security to suppress warnings and includes a suggestion in comments to pass in -subj to remove the full question list:

openssl genrsa -out server.key 2048
openssl rsa -in server.key -out server.key
openssl req -sha256 -new -key server.key -out server.csr -subj '/CN=localhost'
openssl x509 -req -sha256 -days 365 -in server.csr -signkey server.key -out server.crt

Replace 'localhost' with whatever domain you require. You will need to run the first two commands one by one as OpenSSL will prompt for a passphrase.

To combine the two into a .pem file:

cat server.crt server.key > cert.pem

Personally i'm against using culture specific code, i suggest doing:

@String.Format(CultureInfo.CurrentCulture, "{0:C}", @price)

and in your web.config do:

<system.web>
    <globalization culture="en-GB" uiCulture="en-US" />
</system.web>

"Visual Studio does not support std::cout as debug tool for non-console applications"
_{- from Marius Amado-Alves' answer to "How can I see cout output in a non-console application?"}

Which means if you use it, Visual Studio shows nothing in the "output" window (in my case VS2008)

The main difference between “IEnumerable” and “IQueryable” is about where the filter logic is executed. One executes on the client side (in memory) and the other executes on the database.

For example, we can consider an example where we have 10,000 records for a user in our database and let's say only 900 out which are active users, so in this case if we use “IEnumerable” then first it loads all 10,000 records in memory and then applies the IsActive filter on it which eventually returns the 900 active users.

While on the other hand on the same case if we use “IQueryable” it will directly apply the IsActive filter on the database which directly from there will return the 900 active users.

Tested with Visual Studio Code Version 1.26.1 on mac and win

Performing a single click on an HTML element: Simply do element.click(). Most major browsers support this.

To repeat the click more than once: Add an ID to the element to uniquely select it:

<a href="#" target="_blank" id="my-link" onclick="javascript:Test('Test');">Google Chrome</a>

and call the .click() method in your JavaScript code via a for loop:

var link = document.getElementById('my-link');
for(var i = 0; i < 50; i++)
   link.click();

• web server: for every URL, it returns a file. That's all it does. The file is static content, meaning, it is stored somewhere in the server, before you make your request. Most popular web servers are apache http and nginx.
• application server: for every URL, it runs some code, written in some language, generates a response, and returns it. The response doesn't exist in advance, it is generated for your particular request, that is, it is dynamic content. Application servers are different for each language. Some popular examples are tomcat/jetty for java, uwsgi/gunicorn for python.

Almost every page you visit uses both. The static content (eg, images, videos) is served by the web server, and the rest (the parts that are different between you and other users) are generated by the application server.

To Bind the DataTable into the DataGridTextColumn in CodeBehind xaml

    TrkDataGrid.Columns.Add(
      new DataGridTextColumn
      {
        Header = col.ColumnName,

Copied from the stacktrace:

BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib has a constructor with a SessionFactory argument. By adding the @Autowired annotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactory in your case, and provide it as a constructor argument, e.g.

@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
    // ...
}

To run a java file in Android ensure your class has the main method. In Android Studio 3.5 just right click inside the file and select "Run 'Filename.main()'" or click on "Run" on the menu and select "Run Filename" from the resulting drop-down menu.

To search for multiple matches in each file, we can sequence several Select-String calls:

Get-ChildItem C:\Logs |
  where { $_ | Select-String -Pattern 'VendorEnquiry' } |
  where { $_ | Select-String -Pattern 'Failed' } |
  ...

At each step, files that do not contain the current pattern will be filtered out, ensuring that the final list of files contains all of the search terms.

Rather than writing out each Select-String call manually, we can simplify this with a filter to match multiple patterns:

filter MultiSelect-String( [string[]]$Patterns ) {
  # Check the current item against all patterns.
  foreach( $Pattern in $Patterns ) {
    # If one of the patterns does not match, skip the item.
    $matched = @($_ | Select-String -Pattern $Pattern)
    if( -not $matched ) {
      return
    }
  }

  # If all patterns matched, pass the item through.
  $_
}

Get-ChildItem C:\Logs | MultiSelect-String 'VendorEnquiry','Failed',...

Now, to satisfy the "Logtime about 11:30 am" part of the example would require finding the log time corresponding to each failure entry. How to do this is highly dependent on the actual structure of the files, but testing for "about" is relatively simple:

function AboutTime( [DateTime]$time, [DateTime]$target, [TimeSpan]$epsilon ) {
  $time -le ($target + $epsilon) -and $time -ge ($target - $epsilon)
}

PS> $epsilon = [TimeSpan]::FromMinutes(5)
PS> $target = [DateTime]'11:30am'
PS> AboutTime '11:00am' $target $epsilon
False
PS> AboutTime '11:28am' $target $epsilon
True
PS> AboutTime '11:35am' $target $epsilon
True

Swift 3 This works well to check if the string is really empty. Because isEmpty returns true when there's a whitespace.

extension String {
    func isEmptyAndContainsNoWhitespace() -> Bool {
        guard self.isEmpty, self.trimmingCharacters(in: .whitespaces).isEmpty
            else {
               return false
        }
        return true
    }
}

Examples:

let myString = "My String"
myString.isEmptyAndContainsNoWhitespace() // returns false

let myString = ""
myString.isEmptyAndContainsNoWhitespace() // returns true

let myString = " "
myString.isEmptyAndContainsNoWhitespace() // returns false

grid is not a global, it is local to the main function. Change this:

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)

to this:

int nonrecursivecountcells(color grid[ROW_SIZE][COL_SIZE], int row, int column)

Basically you forgot to give that first param a name, grid will do since it matches your code.

declare @tTOTAL int = 0
declare @i integer = 0
declare @itrs integer = 100

while @i < @itrs
begin
declare @t0 datetime = GETDATE()

--your query here

declare @t1 datetime = GETDATE()

set @tTotal = @tTotal + DATEDIFF(MICROSECOND,@t0,@t1)

set @i = @i + 1
end

select @tTotal/@itrs

Brief syntax lesson

Cells(Row, Column) identifies a cell. Row must be an integer between 1 and the maximum for version of Excel you are using. Column must be a identifier (for example: "A", "IV", "XFD") or a number (for example: 1, 256, 16384)

.Cells(Row, Column) identifies a cell within a sheet identified in a earlier With statement:

With ActiveSheet
  :
  .Cells(Row,Column)
  :
End With

If you omit the dot, Cells(Row,Column) is within the active worksheet. So wsh = ActiveWorkbook wsh.Range is not strictly necessary. However, I always use a With statement so I do not wonder which sheet I meant when I return to my code in six months time. So, I would write:

With ActiveSheet
  :
  .Range.  
  :
End With

Actually, I would not write the above unless I really did want the code to work on the active sheet. What if the user has the wrong sheet active when they started the macro. I would write:

With Sheets("xxxx")
  :
  .Range.  
  :
End With

because my code only works on sheet xxxx.

Cells(Row,Column) identifies a cell. Cells(Row,Column).xxxx identifies a property of the cell. Value is a property. Value is the default property so you can usually omit it and the compiler will know what you mean. But in certain situations the compiler can be confused so the advice to include the .Value is good.

Cells(Row,Column) like "*Miami*" will give True if the cell is "Miami", "South Miami", "Miami, North" or anything similar.

Cells(Row,Column).Value = "Miami" will give True if the cell is exactly equal to "Miami". "MIAMI" for example will give False. If you want to accept MIAMI, use the lower case function:

Lcase(Cells(Row,Column).Value) = "miami"  

My suggestions

Your sample code keeps changing as you try different suggestions which I find confusing. You were using Cells(Row,Column) <> "Miami" when I started typing this.

Use

If Cells(i, "A").Value like "*Miami*" And Cells(i, "D").Value like "*Florida*" Then
  Cells(i, "C").Value = "BA"

if you want to accept, for example, "South Miami" and "Miami, North".

Use

If Cells(i, "A").Value = "Miami" And Cells(i, "D").Value like "Florida" Then
  Cells(i, "C").Value = "BA"

if you want to accept, exactly, "Miami" and "Florida".

Use

If Lcase(Cells(i, "A").Value) = "miami" And _
   Lcase(Cells(i, "D").Value) = "florida" Then
  Cells(i, "C").Value = "BA"

if you don't care about case.

With SimpleDateFormat. And steps are -

1. Create your date pattern string
2. Create SimpleDateFormat Object
3. And parse with it.
4. It will return Date Object.

The folder containing your Anaconda installation contains a subfolder called conda-meta with json files for all installed packages, including one for Anaconda itself. Look for anaconda-<version>-<build>.json.

My file is called anaconda-5.0.1-py27hdb50712_1.json, and at the bottom is more info about the version:

"installed_by": "Anaconda2-5.0.1-Windows-x86_64.exe", 
"link": { "source": "C:\\ProgramData\\Anaconda2\\pkgs\\anaconda-5.0.1-py27hdb50712_1" }, 
"name": "anaconda", 
"platform": "win", 
"subdir": "win-64", 
"url": "https://repo.continuum.io/pkgs/main/win-64/anaconda-5.0.1-py27hdb50712_1.tar.bz2", 
"version": "5.0.1"

(Slightly edited for brevity.)

The output from conda -V is the conda version.

It can be changed in the $CATALINA_BASE/conf/server.xml in the <Host />. See the Tomcat documentation, specifically the section in regards to the Host container:

Tomcat 6 Configuration

Tomcat 7 Configuration

The default is webapps relative to the $CATALINA_BASE. An absolute pathname can be used.

Hope that helps.

update 2 ::slotted

::slotted is now supported by all new browsers and can be used with ViewEncapsulation.ShadowDom

https://developer.mozilla.org/en-US/docs/Web/CSS/::slotted

update 1 ::ng-deep

/deep/ was deprecated and replaced by ::ng-deep.

::ng-deep is also already marked deprecated, but there is no replacement available yet.

When ViewEncapsulation.Native is properly supported by all browsers and supports styling accross shadow DOM boundaries, ::ng-deep will probably be discontinued.

original

Angular adds all kinds of CSS classes to the HTML it adds to the DOM to emulate shadow DOM CSS encapsulation to prevent styles of bleeding in and out of components. Angular also rewrites the CSS you add to match these added classes. For HTML added using [innerHTML] these classes are not added and the rewritten CSS doesn't match.

As a workaround try

• for CSS added to the component

/* :host /deep/ mySelector { */
:host ::ng-deep mySelector { 
  background-color: blue;
}

• for CSS added to index.html

/* body /deep/ mySelector { */
body ::ng-deep mySelector {
  background-color: green;
}

>>> (and the equivalent/deep/ but /deep/ works better with SASS) and ::shadow were added in 2.0.0-beta.10. They are similar to the shadow DOM CSS combinators (which are deprecated) and only work with encapsulation: ViewEncapsulation.Emulated which is the default in Angular2. They probably also work with ViewEncapsulation.None but are then only ignored because they are not necessary. These combinators are only an intermediate solution until more advanced features for cross-component styling is supported.

Another approach is to use

@Component({
  ...
  encapsulation: ViewEncapsulation.None,
})

for all components that block your CSS (depends on where you add the CSS and where the HTML is that you want to style - might be all components in your application)

Update

This lookup only features exact matches. If you have an extra space in one of the columns or something similar it will not recognize it.

Since January 7th, 2019, it is possible: unlimited free private repositories on GitHub!
... But for up to three collaborators per private repository.

Nat Friedman just announced it by twitter:

Today(!) we’re thrilled to announce unlimited free private repos for all GitHub users, and a new simplified Enterprise offering:

"New year, new GitHub: Announcing unlimited free private repos and unified Enterprise offering"

For the first time, developers can use GitHub for their private projects with up to three collaborators per repository for free.

Many developers want to use private repos to apply for a job, work on a side project, or try something out in private before releasing it publicly.
Starting today, those scenarios, and many more, are possible on GitHub at no cost.

Public repositories are still free (of course—no changes there) and include unlimited collaborators.

If you want to return to your current working directory:

current_dir=$PWD;cd /path/to/your/command/dir;special command ARGS;cd $current_dir;

1. We are setting a variable current_dir equal to your pwd
2. after that we are going to cd to where you need to run your command
3. then we are running the command
4. then we are going to cd back to our variable current_dir

have MinGW compiler bin directory added to path.

use mingw32-g++ -s -c source_file_name.cpp -o output_file_name.o to compile

then mingw32-g++ -o executable_file_name.exe output_file_name.o to build exe

finally, you run with executable_file_name.exe

As of JDK6U18 following are configurations for the Heap Size.

In the Client JVM, the default Java heap configuration has been modified to improve the performance of today's rich client applications. Initial and maximum heap sizes are larger and settings related to generational garbage collection are better tuned.

The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte. For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes. The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. This amount is at least 8 megabytes and otherwise 1/64 of physical memory up to a physical memory size of 1 gigabyte.

you can try to add these code:

VelocityEngine ve = new VelocityEngine();
String vmPath = request.getSession().getServletContext().getRealPath("${your dir}");
Properties p = new Properties();
p.setProperty("file.resource.loader.path", vmPath+"//");
ve.init(p);

I do this, and pass!

min(df['some_property'])
max(df['some_property'])

The built-in functions work well with Pandas Dataframes.

Java does not allow operator overloading. The preferred approach is to define a method on your class to perform the action: a.add(b) instead of a + b. You can see a summary of the other bits Java left out from C like languages here: Features Removed from C and C++

Note the output while doing the merge - it is saying Fast Forward

In such situations, you want to do:

git merge v1.0 --no-commit --no-ff

Look at these lines:

If yes_ans > no_ans and yes_ans > na_ans

and similar. To what do "yes_ans" etc. refer? You're not using these in the context of a query; the "if exists" condition doesn't extend to the column names you're using inside.

Consider assigning those values to variables you can then use for your conditional flow below. Thus,

if exists (some record)
begin
   set @var = column, @var2 = column2, ...

   if (@var1 > @var2)
      -- do something

end

The return type is also mismatched with the declaration. It would help a lot if you indented, used ANSI-standard punctuation (terminate statements with semicolons), and left out superfluous begin/end - you don't need these for single-statement lines executed as the result of a test.

It can be very useful when flattening a hierarchy and/or mapping objects. Instead of:

if (Model.Model2 == null
  || Model.Model2.Model3 == null
  || Model.Model2.Model3.Model4 == null
  || Model.Model2.Model3.Model4.Name == null)
{
  mapped.Name = "N/A"
}
else
{
  mapped.Name = Model.Model2.Model3.Model4.Name;
}

It can be written like (same logic as above)

mapped.Name = Model.Model2?.Model3?.Model4?.Name ?? "N/A";

DotNetFiddle.Net Working Example.

(the ?? or null-coalescing operator is different than the ? or null conditional operator).

It can also be used out side of assignment operators with Action. Instead of

Action<TValue> myAction = null;

if (myAction != null)
{
  myAction(TValue);
}

It can be simplified to:

myAction?.Invoke(TValue);

DotNetFiddle Example:

using System;

public class Program
{
  public static void Main()
  {
    Action<string> consoleWrite = null;

    consoleWrite?.Invoke("Test 1");

    consoleWrite = (s) => Console.WriteLine(s);

    consoleWrite?.Invoke("Test 2");
  }
}

Result:

Test 2

A JAR file is just a .zip in disguise. The zipped folder contains .class files.

If you're on macOS:

1. Rename the file to possess the '.zip' extension. e.g. myJar.jar -> myJar.zip.
2. Decompress the '.zip' (double click on it). A new folder called 'myJar' will appear
3. Find and replace the .class file with your new .class file.
4. Select all the contents of the folder 'myJar' and choose 'Compress x items'. DO NOT ZIP THE FOLDER ITSELF, ONLY ITS CONTENTS

Miscellaneous - Compiling a single .class file, with reference to a original jar, on macOS

1. Make a file myClass.java, containing your code.
2. Open terminal from Spotlight.
3. javac -classpath originalJar.jar myClass.java This will create your compiled class called myClass.class.

From here, follow the steps above. You can also use Eclipse to compile it, simply reference the original jar by right clicking on the project, 'Build Path' -> 'Add External Archives'. From here you should be able to compile it as a jar, and use the zip technique above to retrieve the class from the jar.

It's to execute a second statement if the first statement ends succesfully. Like an if statement:

 if (1 == 1 && 2 == 2)
  echo "test;"

Its first tries if 1==1, if that is true it checks if 2==2

If you have a Mac you can get jsc a javascript console in OS X (Terminal) by typing

/System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Resources/jsc

in Terminal.app.

You could also run one of your .js script by adding its name as an argument for jsc, like this:

jsc your_awesome_script_name.js

Notice: I use console.log() during development but jsc needs the debug() function instead.

On Ubuntu you have some nice ECMAScript shells at your disposal. Between them it's worth to mention SpiderMonkey. You can add It by sudo apt-get install spidermonkey

On Windows as other people said you can rely on cscript and wscript directly built on the OS.

I would add also another :) way of thinking to the problem, if you have time and like to learn new things i'd like to mention coffee-script that has its own compiler/console and gives you super-correct Javascript out. You can try it also on your browser (link "try coffeescript").

You need DATE_SUB() OR DATE_ADD()

This happens sometimes when there are unbalanced <label> tags in the form.

I received the same error message. To resolve this I just replaced the Oracle.ManagedDataAccess assembly with the older Oracle.DataAccess assembly. This solution may not work if you require new features found in the new assembly. In my case I have many more higher priority issues then trying to configure the new Oracle assembly.

if you are using php7 you can use dirname function with level parameter of 2, for example :

dirname("/usr/local/lib", 2);

the second parameter "2" indicate how many level up

Since Qt 5.8, we now have QDateTime::currentSecsSinceEpoch() to deliver the seconds directly, a.k.a. as real Unix timestamp. So, no need to divide the result by 1000 to get seconds anymore.

Credits: also posted as comment to this answer. However, I think it is easier to find if it is a separate answer.

I wanted to assign the values to an array. So, extending Michael Krelin's approach, I did:

read a[{1..3}] <<< $(echo 2 4 6); echo "${a[1]}|${a[2]}|${a[3]}"

which yields:

2|4|6 

as expected.

Not sure whether is it already posted, but this combo worked for me:

php artisan clear-compiled 
composer dump-autoload
php artisan optimize

A simple JSF Url Prettyfier filter based in the steps of BalusC's answer. The filter forwards all the requests starting with the /ui path (supposing you've got all your xhtml files stored there) to the same path, but adding the xhtml suffix.

public class UrlPrettyfierFilter implements Filter {

    private static final String JSF_VIEW_ROOT_PATH = "/ui";

    private static final String JSF_VIEW_SUFFIX = ".xhtml";

    @Override
    public void destroy() {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest httpServletRequest = ((HttpServletRequest) request);
        String requestURI = httpServletRequest.getRequestURI();
        //Only process the paths starting with /ui, so as other requests get unprocessed. 
        //You can register the filter itself for /ui/* only, too
        if (requestURI.startsWith(JSF_VIEW_ROOT_PATH) 
                && !requestURI.contains(JSF_VIEW_SUFFIX)) {
            request.getRequestDispatcher(requestURI.concat(JSF_VIEW_SUFFIX))
                .forward(request,response);
        } else {
            chain.doFilter(httpServletRequest, response);
        }
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {

    }

}

Unless your dataset is going to stay pretty small, you might want to consider using a relational database. It will do exactly what you want: make it easy to add counts, selecting subsets of counts, and even aggregate counts by state, county, occupation, or any combination of these.

we are using MSMQ in our system, this error message came. The reason was our queue was full and we did not handle the error logging mechanism properly so we were getting the above exception instead of msmq ful. We cleared the messages then it is working fine.

ok,most of them have shown you something good. Let'me give you this:

// ToString Change arg to string
func ToString(arg interface{}, timeFormat ...string) string {
    if len(timeFormat) > 1 {
        log.SetFlags(log.Llongfile | log.LstdFlags)
        log.Println(errors.New(fmt.Sprintf("timeFormat's length should be one")))
    }
    var tmp = reflect.Indirect(reflect.ValueOf(arg)).Interface()
    switch v := tmp.(type) {
    case int:
        return strconv.Itoa(v)
    case int8:
        return strconv.FormatInt(int64(v), 10)
    case int16:
        return strconv.FormatInt(int64(v), 10)
    case int32:
        return strconv.FormatInt(int64(v), 10)
    case int64:
        return strconv.FormatInt(v, 10)
    case string:
        return v
    case float32:
        return strconv.FormatFloat(float64(v), 'f', -1, 32)
    case float64:
        return strconv.FormatFloat(v, 'f', -1, 64)
    case time.Time:
        if len(timeFormat) == 1 {
            return v.Format(timeFormat[0])
        }
        return v.Format("2006-01-02 15:04:05")
    case jsoncrack.Time:
        if len(timeFormat) == 1 {
            return v.Time().Format(timeFormat[0])
        }
        return v.Time().Format("2006-01-02 15:04:05")
    case fmt.Stringer:
        return v.String()
    case reflect.Value:
        return ToString(v.Interface(), timeFormat...)
    default:
        return ""
    }
}

I had a similar issue before even with this approach df.loc[:,'industry'] = 'yyy', but once I refreshed the notebook, it ran well.

You may want to try refreshing the cells after you have df.loc[:,'industry'] = 'yyy'.

Try this:

num_days = later_date - earlier_date

You don't need negative lookahead. There is working example:

/([\s\S]*?)(red|green|blue|)/g

Description:

• [\s\S] - match any character
• * - match from 0 to unlimited from previous group
• ? - match as less as possible
• (red|green|blue|) - match one of this words or nothing
• g - repeat pattern

Example:

whiteredwhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredgreenbluewhiteredwhiteredwhiteredwhiteredwhiteredwhiteredgreenbluewhiteredwhiteredwhiteredwhiteredwhiteredredgreenredgreenredgreenredgreenredgreenbluewhiteredbluewhiteredbluewhiteredbluewhiteredbluewhiteredwhite

All tables within bootstrap stretch according to the container they're in. You can put your tables inside a .span element to control the size. This SO Question may help you out

Why do Twitter Bootstrap tables always have 100% width?

Although this does not help you right away, there is an alternative that can work with both Unix (fcntl) and Windows (win32 api calls), called: portalocker

It describes itself as a cross-platform (posix/nt) API for flock-style file locking for Python. It basically maps fcntl to win32 api calls.

The original code at http://code.activestate.com/recipes/65203/ can now be installed as a separate package - https://pypi.python.org/pypi/portalocker

You need to go to user accounts and enable Guest Account, its default disabled. Once you do this, you share any folder and add the guest account to the list of users who can accesss that specific folder, this also includes to Turn off password Protected Sharing in 'Advanced Sharing Settings'

The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.

Partial mocking of a class is also supported via Spy in mockito

List list = new LinkedList();
List spy = spy(list);

//optionally, you can stub out some methods:
when(spy.size()).thenReturn(100);

//using the spy calls real methods
spy.add("one");
spy.add("two");

//size() method was stubbed - 100 is printed
System.out.println(spy.size());

Check the 1.10.19 and 2.7.22 docs for detailed explanation.

I dont believe this is possible. Your best bet is to get something like iShowU and capture from the simulator.

You can use.`

        Model.update({
            'type': "newuser"
        }, {
            $set: {
                email: "[email protected]",
                phoneNumber:"0123456789"
            }
        }, {
            multi: true
        },
        function(err, result) {
            console.log(result);
            console.log(err);
        })  `

To add my 2 cents, I got this same issue when I m accidentally sending null as the ID. Below code depicts my scenario (and OP didn't mention any specific scenario).

Employee emp = new Employee();
emp.setDept(new Dept(deptId)); // --> when deptId PKID is null, same error will be thrown
// calls to other setters...
em.persist(emp);

Here I m setting the existing department id to a new employee instance without actually getting the department entity first, as I don't want to another select query to fire.

In some scenarios, deptId PKID is coming as null from calling method and I m getting the same error.

So, watch for null values for PK ID

There really aren't any differences.

" is processed as " which is the decimal equivalent of &x22; which is the ISO 8859-1 equivalent of ".

The only reason you may be against using " is because it was mistakenly omitted from the HTML 3.2 specification.

Otherwise it all boils down to personal preference.

If you want to find the last populated cell in a particular column, the best method is:

Range("A" & Rows.Count).End(xlUp).Row

This code uses the very last cell in the entire column (65536 for Excel 2003, 1048576 in later versions), and then find the first populated cell above it. This has the ability to ignore "breaks" in your data and find the true last row.

I was getting this same error, but for me this was due to a method in a base class (in Project A) having the output type changed from a non-void type to void. A child class existed in Project B (which I didn't want used and had marked obsolete) that I missed when performing this update and hence started throwing this error.

1>CSC : error CS8104: An error occurred while writing the output file: System.NullReferenceException: Object reference not set to an instance of an object.

Original Code:

[Obsolete("Calling this method will throw an error")]
public override CompletionStatus Run()
{
    throw new CustomException("Run process not supported.");
}

Revised Code:

[Obsolete("Calling this method will throw an error")]
public override void Run()
{
    throw new CustomException("Run process not supported.");
}

In VS 2015 it can be achieved by Team Explorer > Connect > Manage Connections and selecting the team project again. In case of there exist more than one account in VS, Team Explorer asks for which account to use to connect to the team project.

I still doubt about this, but I've tried it at my script and I'm using xdebug to know how it will affect my app memory usage. The script is set on my function like this :

function gen_table_data($serv, $coorp, $type, $showSql = FALSE, $table = 'ireg_idnts') {
    $sql = "SELECT COUNT(`operator`) `operator` FROM $table WHERE $serv = '$coorp'";
    if($showSql === FALSE) {
        $sql = mysql_query($sql) or die(mysql_error());
        $data = mysql_fetch_array($sql);
        return $data[0];
    } else echo $sql;
}

And I add unset just before the return code and it give me : 160200 then I try to change it with $sql = NULL and it give me : 160224 :)

But there is something unique on this comparative when I am not using unset() or NULL, xdebug give me 160144 as memory usage

So, I think giving line to use unset() or NULL will add process to your application and it will be better to stay origin with your code and decrease the variable that you are using as effective as you can .

Correct me if I'm wrong, thanks

There is an interesting discussion here: http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/307d658a-f677-40f2-bdef-e6352b0bfe9e/ My understanding of this thread is that freeing small allocations are not reflected in Private Bytes or Working Set.

Long story short:

if I call

p=malloc(1000);
free(p);

then the Private Bytes reflect only the allocation, not the deallocation.

if I call

p=malloc(>512k);
free(p);

then the Private Bytes correctly reflect the allocation and the deallocation.

Your class might implement the Comparable interface to achieve the same functionality. Your class should implement the compareTo() method declared in the interface.

public class MyClass implements Comparable<MyClass>{

    String a;

    public MyClass(String ab){
        a = ab;
    }

    // returns an int not a boolean
    public int compareTo(MyClass someMyClass){ 

        /* The String class implements a compareTo method, returning a 0 
           if the two strings are identical, instead of a boolean.
           Since 'a' is a string, it has the compareTo method which we call
           in MyClass's compareTo method.
        */

        return this.a.compareTo(someMyClass.a);

    }

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

I had removed files from Compile Sources in Build Phases in Targets. I added main.m and it worked.

1. Somewhere, nearby the assembly you're going to run.
2. Use reflection to get path to your executing assembly, then do some magic to locate your HTML file.

Like this:

var myAssembly = System.Reflection.Assembly.GetEntryAssembly();
var myAssemblyLocation = System.IO.Path.GetDirectoryName(a.Location);
var myHtmlPath = Path.Combine(myAssemblyLocation, "my.html");

Just found this extension to do it - simple and effective.

Although it looks logical, the accepted answer is incorrect because JavaScript dates don't work like that.

It's super important to note here that the numerical value of a date (i.e., new Date()-0 or Date.now()) in JavaScript is always measured as millseconds since the epoch which is a timezone-free quantity based on a precise exact instant in the history of the universe. You do not need to add or subtract anything to the numerical value returned from Date() to convert the numerical value into a timezone, because the numerical value has no timezone. If it did have a timezone, everything else in JavaScript dates wouldn't work.

Timezones, leap years, leap seconds, and all of the other endlessly complicated adjustments to our local times and dates, are based on this consistent and unambiguous numerical value, not the other way around.

Here are examples of how the numerical value of a date (provided to the date constructor) is independent of timezone:

In Central Standard Time:

new Date(0);
// Wed Dec 31 1969 18:00:00 GMT-0600 (CST)

In Anchorage, Alaska:

new Date(0);
// Wed Dec 31 1969 15:00:00 GMT-0900 (AHST)

In Paris, France:

new Date(0);
// Thu Jan 01 1970 01:00:00 GMT+0100 (CET)

It is critical to observe that in ALL cases, based on the timezone-free epoch offset of zero milliseconds, the resulting time is identical. 1 am in Paris, France is the exact same moment as 3 pm the day before in Anchorage, Alaska, which is the exact same moment as 6 pm in Chicago, Illinois.

For this reason, the accepted answer on this page is incorrect. Observe:

// Create a date.
   date = new Date();
// Fri Jan 27 2017 18:16:35 GMT-0600 (CST)


// Observe the numerical value of the date.
   date.valueOf();
// 1485562595732
// n.b. this value has no timezone and does not need one!!


// Observe the incorrectly "corrected" numerical date value.
   date.valueOf() + date.getTimezoneOffset() * 60000;
// 1485584195732


// Try out the incorrectly "converted" date string.
   new Date(date.valueOf() + date.getTimezoneOffset() * 60000);
// Sat Jan 28 2017 00:16:35 GMT-0600 (CST)

/* Not the correct result even within the same script!!!! */

If you have a date string in another timezone, no conversion to the resulting object created by new Date("date string") is needed. Why? JavaScript's numerical value of that date will be the same regardless of its timezone. JavaScript automatically goes through amazingly complicated procedures to extract the original number of milliseconds since the epoch, no matter what the original timezone was.

The bottom line is that plugging a textual date string x into the new Date(x) constructor will automatically convert from the original timezone, whatever that might be, into the timezone-free epoch milliseconds representation of time which is the same regardless of any timezone. In your actual application, you can choose to display the date in any timezone that you want, but do NOT add/subtract to the numerical value of the date in order to do so. All the conversion already happened at the instant the date object was created. The timezone isn't even there anymore, because the date object is instantiated using a precisely-defined and timezone-free sense of time.

The timezone only begins to exist again when the user of your application is considered. The user does have a timezone, so you simply display that timezone to the user. But this also happens automatically.

Let's consider a couple of the dates in your original question:

   date1 = new Date("Fri Jan 20 2012 11:51:36 GMT-0300");
// Fri Jan 20 2012 08:51:36 GMT-0600 (CST)


   date2 = new Date("Fri Jan 20 2012 11:51:36 GMT-0300")
// Fri Jan 20 2012 08:51:36 GMT-0600 (CST)

The console already knows my timezone, and so it has automatically shown me what those times mean to me.

And if you want to know the time in GMT/UTC representation, also no conversion is needed! You don't change the time at all. You simply display the UTC string of the time:

    date1.toUTCString();
// "Fri, 20 Jan 2012 14:51:36 GMT"

Code that is written to convert timezones numerically using the numerical value of a JavaScript date is almost guaranteed to fail. Timezones are way too complicated, and that's why JavaScript was designed so that you didn't need to.

You can import the text file using the read_table command as so:

import pandas as pd
df=pd.read_table('output_list.txt',header=None)

For me, VS uses Firefox for the default browser. Restarting VS and closing all Firefox windows seems to resolve this issue.

add Microsoft.AspNet.Mvc nuget package.

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

Your data may not be what you expect -- it seems you're expecting, but not getting, floats.

A simple solution to figuring out where this occurs would be to add a try/except to the for-loop:

for i in range(0,N):
    w=f[i].split()
    l1=w[1:8]
    l2=w[8:15]
    try:
      list1=[float(x) for x in l1]
      list2=[float(x) for x in l2]
    except ValueError, e:
      # report the error in some way that is helpful -- maybe print out i
    result=stats.ttest_ind(list1,list2)
    print result[1]

This will list all jpg files in the folder you define under url: and append them to a div as a paragraph. Can do it with ul li as well.

$.ajax({
  url: "YOUR FOLDER",
  success: function(data){
     $(data).find("a:contains(.jpg)").each(function(){
        // will loop through 
        var images = $(this).attr("href");

        $('<p></p>').html(images).appendTo('a div of your choice')

     });
  }
});

ob_start();  // turns on output buffering
$foo->bar();  // all output goes only to buffer
ob_clean();  // delete the contents of the buffer, but remains buffering active
$foo->render(); // output goes to buffer
ob_flush(); // send buffer output
$none = ob_get_contents();  // buffer content is now an empty string
ob_end_clean();  // turn off output buffering

Buffers can be nested, so while one buffer is active, another ob_start() activates a new buffer. So ob_end_flush() and ob_flush() are not really sending the buffer to the output, but to the parent buffer. And only when there is no parent buffer, contents is sent to browser or terminal.

Nicely explained here: https://phpfashion.com/everything-about-output-buffering-in-php

According to the latest pandas documentation you can read a csv file selecting only the columns which you want to read.

import pandas as pd

df = pd.read_csv('some_data.csv', usecols = ['col1','col2'], low_memory = True)

Here we use usecols which reads only selected columns in a dataframe.

We are using low_memory so that we Internally process the file in chunks.

You could make an array the same size as the ArrayList and then make an iterated for loop to index the items and insert them into the array.

What about:

If Not I = x Then

  ' Do something '

End If

' Move to next item '

In my case I was running Tensorflow Docker container in Ubuntu 20.04 :Run your docker container in One terminal , I ran it with

How does your .NET Webservice look like?

I had the same effect using ksoap 2.3 from code.google.com. I followed the tutorial on The Code Project (which is great BTW.)

And everytime I used

    Integer result = (Integer)envelope.getResponse();

to get the result of a my webservice (regardless of the type, I tried Object, String, int) I ran into the org.ksoap2.serialization.SoapPrimitive exception.

I found a solution (workaround). The first thing I had to do was to remove the "SoapRpcMethod() attribute from my webservice methods.

    [SoapRpcMethod(), WebMethod]
    public Object GetInteger1(int i)
    {
        // android device will throw exception
        return 0;
    }

    [WebMethod]
    public Object GetInteger2(int i)
    {
        // android device will get the value
        return 0;
    }

Then I changed my Android code to:

    SoapPrimitive result = (SoapPrimitive)envelope.getResponse();

However, I get a SoapPrimitive object, which has a "value" filed that is private. Luckily the value is passed through the toString() method, so I use Integer.parseInt(result.toString()) to get my value, which is enough for me, because I don't have any complex types that I need to get from my Web service.

Here is the full source:

private static final String SOAP_ACTION = "http://tempuri.org/GetInteger2";
private static final String METHOD_NAME = "GetInteger2";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://10.0.2.2:4711/Service1.asmx";

public int GetInteger2() throws IOException, XmlPullParserException {
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    PropertyInfo pi = new PropertyInfo();
    pi.setName("i");
    pi.setValue(123);
    request.addProperty(pi);

    SoapSerializationEnvelope envelope =
        new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);

    AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
    androidHttpTransport.call(SOAP_ACTION, envelope);

    SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
    return Integer.parseInt(result.toString());
}

You can use trunc and to_date as follows:

select TO_CHAR (g.FECHA, 'DD-MM-YYYY HH24:MI:SS') fecha_salida, g.NUMERO_GUIA, g.BOD_ORIGEN, g.TIPO_GUIA, dg.DOC_NUMERO, dg.* 
from ils_det_guia dg, ils_guia g
where dg.NUMERO_GUIA = g.NUMERO_GUIA and dg.TIPO_GUIA = g.TIPO_GUIA and dg.BOD_ORIGEN = g.BOD_ORIGEN
and dg.LAB_CODIGO = 56 
and trunc(g.FECHA) > to_date('01/02/15','DD/MM/YY')
order by g.FECHA;

Use a while loop that checks for the truthfulness of the array:

while array:
    value = array.pop(0)
    # do some calculation here

And it should do it without any errors or funny behaviour.

To capitalize on the answer of Alex D, using refinements:

module CoreExtensions
  module Integerable
    refine String do
      def integer?
        Integer(self)
      rescue ArgumentError
        false
      else
        true
      end
    end
  end
end

Later, in you class:

require 'core_ext/string/integerable'

class MyClass
  using CoreExtensions::Integerable

  def method
    'my_string'.integer?
  end
end

The "pre Windows 2000" name i.e. DOMAIN\SomeBody, the Somebody portion is known as sAMAccountName.

So try:

   {
     adSearch.Filter = "(sAMAccountName=someuser)";
     SearchResult adSearchResult = adSearch.FindOne();

You will see this error in case a some class in your library file you have in classpath has reference to non-existing classe(s) which could be in another jar file. Here, I received this error when I did not add org.springframework.beans-3.1.2.RELEASE.jar and had extended a class from org.springframework.jdbc.core.support.JdbcDaoSupport, which was in org.springframework.jdbc-3.1.2.RELEASE.jar of my classpath.

What worked for me is I placed the file under

src/main/java/myfile.log

and

InputStream is = getClass().getClassLoader().getResourceAsStream("myfile.log");
        
        if (is == null) {
            throw new FileNotFoundException("Log file not provided");
        }

While I upvoted EdChum's answer, which is the most direct answer to the question the OP posed, it does not really solve the performance problem (it still relies on python datetime objects, and hence any operation on them will be not vectorized - that is, it will be slow).

A better performing alternative is to use df['dates'].dt.floor('d'). Strictly speaking, it does not "keep only date part", since it just sets the time to 00:00:00. But it does work as desired by the OP when, for instance:

• printing to screen
• saving to csv
• using the column to groupby

... and it is much more efficient, since the operation is vectorized.

EDIT: in fact, the answer the OP's would have preferred is probably "recent versions of pandas do not write the time to csv if it is 00:00:00 for all observations".

I understand this is a discussion point for a node application, but in the interest of universal JavaScript applications running on a node server, which is how I arrived at this post, I have been researching this for a universal / isomorphic react app I have been building, and the package abab worked for me. In fact it was the only solution I could find that worked, rather than using the Buffer method also mentioned (I had typescript issues).

(This package is used by jsdom, which in turn is used by the window package.)

Getting back to my point; based on this, perhaps if this functionality is already written as an npm package like the one you mentioned, and has it's own algorithm based on W3 spec, you could install and use the abab package rather than writing you own function that may or may not be accurate based on encoding.

---EDIT---

I started having weird issues today with encoding (not sure why it's started happening now) with package abab. It seems to encode correctly most of the time, but sometimes on front end it encodes incorrectly. Spent a long time trying to debug, but switched to package base-64 as recommended, and it worked straight away. Definitely seemed to be down to the base64 algorithm of abab.

You can also write a custom query using @Query

@Query(value = "from EntityClassTable t where yourDate BETWEEN :startDate AND :endDate")
public List<EntityClassTable> getAllBetweenDates(@Param("startDate")Date startDate,@Param("endDate")Date endDate);

Here is an example that replaces all instances of 1 or more white space characters in a column with an underscore using regular expression -

select distinct on (pd)
regexp_replace(rndc.pd, '\\s+', '_','g') as pd
from rndc14_ndc_mstr rndc;

Here's a simple way I wrote up for you. :)

>>> number = '123,456,789.908'.replace(',', '') # '123456789.908'
>>> float(number)
123456789.908

Each deployed webapp has a context.xml file that lives in

$CATALINA_BASE/conf/[enginename]/[hostname]

(conf/Catalina/localhost by default)

and has the same name as the webapp (manager.xml in this case). If no file is present, default values are used.

So, you need to create a file conf/Catalina/localhost/manager.xml and specify the rule you want to allow remote access. For example, the following content of manager.xml will allow access from all machines:

<Context privileged="true" antiResourceLocking="false" 
         docBase="${catalina.home}/webapps/manager">
    <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^YOUR.IP.ADDRESS.HERE$" />
</Context>

Note that the allow attribute of the Valve element is a regular expression that matches the IP address of the connecting host. So substitute your IP address for YOUR.IP.ADDRESS.HERE (or some other useful expression).

Other Valve classes cater for other rules (e.g. RemoteHostValve for matching host names). Earlier versions of Tomcat use a valve class org.apache.catalina.valves.RemoteIpValve for IP address matching.

Once the changes above have been made, you should be presented with an authentication dialog when accessing the manager URL. If you enter the details you have supplied in tomcat-users.xml you should have access to the Manager.

String methodName= "...";

        m.invoke(null, new Object[] {args});
        break;
    }

It could be that the gradle-2.1 distribution specified by the wrapper was not downloaded properly. This was the root cause of the same problem in my environment.

Look into this directory:

ls -l ~/.gradle/wrapper/dists/

In there you should find a gradle-2.1 folder. Delete it like so:

rm -rf ~/.gradle/wrapper/dists/gradle-2.1-bin/

Restart IntelliJ, after that it will restart the download from the beginning and hopefully work.

In the comments in the answer, it does not explicitly state that nextTick shifted from Macrosemantics to Microsemantics.

before node 0.9 (when setImmediate was introduced), nextTick operated at the start of the next callstack.

since node 0.9, nextTick operates at the end of the existing callstack, whereas setImmediate is at the start of the next callstack

I couldn't uninstall yarn on windows and I tried every single answer here, but every time I ran yarn -v, the command worked. But then I realized that there is another thing that can affect this.

If you on windows (not sure if this also happens in mac) and using nvm, one problem that can happen is that you have installed nvm without uninstalling npm, and the working yarn command is from your old yarn version from the old npm.

So what you need to do is follow this step from the nvm docs

You should also delete the existing npm install location (e.g. "C:\Users<user>\AppData\Roaming\npm"), so that the nvm install location will be correctly used instead. Backup the global npmrc config (e.g. C:\Users&lt;user>\AppData\Roaming\npm\etc\npmrc), if you have some important settings there, or copy the settings to the user config C:\Users&lt;user>.npmrc.

And to confirm that you problem is with the old npm, you will probably see the yarn.cmd file inside the C:\Users\<user>\AppData\Roaming\npm folder.

I'm not sure what you mean by "undo" the change. You can remove the core.excludesfile setting like this:

git config --global --unset core.excludesfile

And of course you can simply edit the config file:

git config --global --edit

...and then remove the setting by hand.

Short answer

1. Reattach without ejecting others: screen -x
2. Get list of displays: ^A *, select the one to disconnect, press d

Explained answer

Background: When I was looking for the solution with same problem description, I have always landed on this answer. I would like to provide more sensible solution. (For example: the other attached screen has a different size and a I cannot force resize it in my terminal.)

Note: PREFIX is usually ^A = ctrl+a

Note: the display may also be called:

• "user front-end" (in at command manual in screen)
• "client" (tmux vocabulary where this functionality is detach-client)
• "terminal" (as we call the window in our user interface) /depending on

1. Reattach a session: screen -x

-x attach to a not detached screen session without detaching it

2. List displays of this session: PREFIX *

It is the default key binding for: PREFIX :displays. Performing it within the screen, identify the other display we want to disconnect (e.g. smaller size). (Your current display is displayed in brighter color/bold when not selected).

term-type   size         user interface           window       Perms
---------- ------- ---------- ----------------- ----------     -----
 screen     240x60         you@/dev/pts/2      nb  0(zsh)        rwx
 screen      78x40         you@/dev/pts/0      nb  0(zsh)        rwx

Using arrows ? ?, select the targeted display, press d If nothing happens, you tried to detach your own display and screen will not detach it. If it was another one, within a second or two, the entry will disappear.

Press ENTER to quit the listing.

Optionally: in order to make the content fit your screen, reflow: PREFIX F (uppercase F)

Excerpt from man page of screen:

displays

Shows a tabular listing of all currently connected user front-ends (displays). This is most useful for multiuser sessions. The following keys can be used in displays list:

• mouseclick Move to the selected line. Available when "mousetrack" is set to on.
• space Refresh the list
• d Detach that display
• D Power detach that display
• C-g, enter, or escape Exit the list

At least as of CKEDITOR 4.4.5, you can set up a listener for every change to the editor's contents, rather than running a timer:

CKEDITOR.on("instanceCreated", function(event) {
    event.editor.on("change", function () {
        $("#trackingDiv").html(event.editor.getData());
    });
});

I realize this may be too late for the OP, and doesn't show as the correct answer or have any votes (yet), but I thought I'd update the post for future readers.

A simple view like this was giving me the ORA-01861 error when executed from Entity Framework:

create view myview as 
select * from x where x.initialDate >= '01FEB2021'

Just did something like this to fix it:

create view myview as 
select * from x where x.initialDate >= TO_DATE('2021-02-01', 'YYYY-MM-DD')

I think the problem is EF date configuration is not the same as Oracle's.

In my case I had removed a locale and generated another locale. Database failed to open because of fatal errors in the postgresql.conf file, on 'lc_messages', 'lc_monetary', 'lc_numberic', and 'lc_time'.

Restoring the locale sorted it out for me.

As per the HTML provided:

<select id="fruits01" class="select" name="fruits">
  <option value="0">Choose your fruits:</option>
  <option value="1">Banana</option>
  <option value="2">Mango</option>
</select>

To select an <option> element from a html-select menu you have to use the Select Class. Moreover, as you have to interact with the drop-down-menu you have to induce WebDriverWait for the element_to_be_clickable().

To select the <option> with text as Mango from the dropdown you can use you can use either of the following Locator Strategies:

• Using ID attribute and select_by_visible_text() method:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.support.ui import Select
  
  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "fruits01"))))
  select.select_by_visible_text("Mango")
  

• Using CSS-SELECTOR and select_by_value() method:

  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select.select[name='fruits']"))))
  select.select_by_value("2")
  

• Using XPATH and select_by_index() method:

  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "//select[@class='select' and @name='fruits']"))))
  select.select_by_index(2)
  

You could simply use ^[\w.]+ to match A-Z, a-z, 0-9 and _

Whenever you create child class object then that object has all the features of parent class. Here Super() is the facilty for accession parent.

If you write super() at that time parents's default constructor is called. same if you write super.

this keyword refers the current object same as super key word facilty for accessing parents.

Here is a example of embedding without an iFrame:

<div style="width: 560px; height: 315px; float: none; clear: both; margin: 2px auto;">
  <embed
    src="https://www.youtube.com/embed/J---aiyznGQ?autohide=1&autoplay=1"
    wmode="transparent"
    type="video/mp4"
    width="100%" height="100%"
    allow="autoplay; encrypted-media; picture-in-picture"
    allowfullscreen
    title="Keyboard Cat"
  >
</div>

compare to regular iframe "embed" code from YouTube:

<iframe
  width="560"
  height="315"
  src="https://www.youtube.com/embed/J---aiyznGQ?autoplay=1"
  frameborder="0"
  allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture"
  allowfullscreen>
</iframe>

and as far as HTML5 goes, use <object> tag like so (corrected):

<object
  style="width: 820px; height: 461.25px; float: none; clear: both; margin: 2px auto;"
  data="http://www.youtube.com/embed/J---aiyznGQ?autoplay=1">
</object>

This is working as documented. Any paths specified in PYTHONPATH are documented as normally coming after the working directory but before the standard interpreter-supplied paths. sys.path.append() appends to the existing path. See here and here. If you want a particular directory to come first, simply insert it at the head of sys.path:

import sys
sys.path.insert(0,'/path/to/mod_directory')

That said, there are usually better ways to manage imports than either using PYTHONPATH or manipulating sys.path directly. See, for example, the answers to this question.

My favorite class, runs any method on another thread with just 2 lines of code.

class ThreadedExecuter<T> where T : class
{
    public delegate void CallBackDelegate(T returnValue);
    public delegate T MethodDelegate();
    private CallBackDelegate callback;
    private MethodDelegate method;

    private Thread t;

    public ThreadedExecuter(MethodDelegate method, CallBackDelegate callback)
    {
        this.method = method;
        this.callback = callback;
        t = new Thread(this.Process);
    }
    public void Start()
    {
        t.Start();
    }
    public void Abort()
    {
        t.Abort();
        callback(null); //can be left out depending on your needs
    }
    private void Process()
    {
        T stuffReturned = method();
        callback(stuffReturned);
    }
}

usage

    void startthework()
    {
        ThreadedExecuter<string> executer = new ThreadedExecuter<string>(someLongFunction, longFunctionComplete);
        executer.Start();
    }
    string someLongFunction()
    {
        while(!workComplete)
            WorkWork();
        return resultOfWork;
    }
    void longFunctionComplete(string s)
    {
        PrintWorkComplete(s);
    }

Beware that longFunctionComplete will NOT execute on the same thread as starthework.

For methods that take parameters you can always use closures, or expand the class.

If you want to keep the innerHTML of the element and only strip the outermost tag, you can do this:

$(".contentToStrip").each(function(){
  $(this).replaceWith($(this).html());
});

As declaration of array list in java is like

public class ArrayList<E> extends AbstractList<E> implements List<E>, RandomAccess, Cloneable, Serializable  

There is numerous way you can create and initialize array list in java.

 1) List list = new ArrayList();

 2) List<type> myList = new ArrayList<>();

 3) List<type> myList = new ArrayList<type>();

 4) Using Utility class

    List<Integer> list = Arrays.asList(8, 4);
    Collections.unmodifiableList(Arrays.asList("a", "b", "c"));

 5) Using static factory method

    List<Integer> immutableList = List.of(1, 2);


 6) Creation and initializing at a time

    List<String> fixedSizeList = Arrays.asList(new String[] {"Male", "Female"});



 Again you can create different types of list. All has their own characteristics

 List a = new ArrayList();
 List b = new LinkedList();
 List c = new Vector(); 
 List d = new Stack(); 
 List e = new CopyOnWriteArrayList();

Maybe ICMP packets are blocked by your (mobile) provider. If this code doesn't work on the emulator try to sniff via wireshark or any other sniffer and have a look whats up on the wire when you fire the isReachable() method.

You may also find some info in your device log.

I had a similar issue when attempting to start a process without showing the console window. I tested with several different combinations of property values until I found one that exhibited the behavior I wanted.

Here is a page detailing why the UseShellExecute property must be set to false.
http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.createnowindow.aspx

Under Remarks section on page:

If the UseShellExecute property is true or the UserName and Password properties are not null, the CreateNoWindow property value is ignored and a new window is created.

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = fullPath;
startInfo.Arguments = args;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;

Process processTemp = new Process();
processTemp.StartInfo = startInfo;
processTemp.EnableRaisingEvents = true;
try
{
    processTemp.Start();
}
catch (Exception e)
{
    throw;
}

At the moment I'm selecting like this:

$('a[data-attribute=true]')

Which seems to work just fine, but it would be nice if jQuery was able to select by that attribute without the 'data-' prefix.

I haven't tested this with data added to elements via jQuery dynamically, so that could be the downfall of this method.

How do I check whether a file exists, using Python, without using a try statement?

Now available since Python 3.4, import and instantiate a Path object with the file name, and check the is_file method (note that this returns True for symlinks pointing to regular files as well):

>>> from pathlib import Path
>>> Path('/').is_file()
False
>>> Path('/initrd.img').is_file()
True
>>> Path('/doesnotexist').is_file()
False

If you're on Python 2, you can backport the pathlib module from pypi, pathlib2, or otherwise check isfile from the os.path module:

>>> import os
>>> os.path.isfile('/')
False
>>> os.path.isfile('/initrd.img')
True
>>> os.path.isfile('/doesnotexist')
False

Now the above is probably the best pragmatic direct answer here, but there's the possibility of a race condition (depending on what you're trying to accomplish), and the fact that the underlying implementation uses a try, but Python uses try everywhere in its implementation.

Because Python uses try everywhere, there's really no reason to avoid an implementation that uses it.

But the rest of this answer attempts to consider these caveats.

Longer, much more pedantic answer

Available since Python 3.4, use the new Path object in pathlib. Note that .exists is not quite right, because directories are not files (except in the unix sense that everything is a file).

>>> from pathlib import Path
>>> root = Path('/')
>>> root.exists()
True

So we need to use is_file:

>>> root.is_file()
False

Here's the help on is_file:

is_file(self)
    Whether this path is a regular file (also True for symlinks pointing
    to regular files).

So let's get a file that we know is a file:

>>> import tempfile
>>> file = tempfile.NamedTemporaryFile()
>>> filepathobj = Path(file.name)
>>> filepathobj.is_file()
True
>>> filepathobj.exists()
True

By default, NamedTemporaryFile deletes the file when closed (and will automatically close when no more references exist to it).

>>> del file
>>> filepathobj.exists()
False
>>> filepathobj.is_file()
False

If you dig into the implementation, though, you'll see that is_file uses try:

def is_file(self):
    """
    Whether this path is a regular file (also True for symlinks pointing
    to regular files).
    """
    try:
        return S_ISREG(self.stat().st_mode)
    except OSError as e:
        if e.errno not in (ENOENT, ENOTDIR):
            raise
        # Path doesn't exist or is a broken symlink
        # (see https://bitbucket.org/pitrou/pathlib/issue/12/)
        return False

Race Conditions: Why we like try

We like try because it avoids race conditions. With try, you simply attempt to read your file, expecting it to be there, and if not, you catch the exception and perform whatever fallback behavior makes sense.

If you want to check that a file exists before you attempt to read it, and you might be deleting it and then you might be using multiple threads or processes, or another program knows about that file and could delete it - you risk the chance of a race condition if you check it exists, because you are then racing to open it before its condition (its existence) changes.

Race conditions are very hard to debug because there's a very small window in which they can cause your program to fail.

But if this is your motivation, you can get the value of a try statement by using the suppress context manager.

Avoiding race conditions without a try statement: suppress

Python 3.4 gives us the suppress context manager (previously the ignore context manager), which does semantically exactly the same thing in fewer lines, while also (at least superficially) meeting the original ask to avoid a try statement:

from contextlib import suppress
from pathlib import Path

Usage:

>>> with suppress(OSError), Path('doesnotexist').open() as f:
...     for line in f:
...         print(line)
... 
>>>
>>> with suppress(OSError):
...     Path('doesnotexist').unlink()
... 
>>> 

For earlier Pythons, you could roll your own suppress, but without a try will be more verbose than with. I do believe this actually is the only answer that doesn't use try at any level in the Python that can be applied to prior to Python 3.4 because it uses a context manager instead:

class suppress(object):
    def __init__(self, *exceptions):
        self.exceptions = exceptions
    def __enter__(self):
        return self
    def __exit__(self, exc_type, exc_value, traceback):
        if exc_type is not None:
            return issubclass(exc_type, self.exceptions)

Perhaps easier with a try:

from contextlib import contextmanager

@contextmanager
def suppress(*exceptions):
    try:
        yield
    except exceptions:
        pass

Other options that don't meet the ask for "without try":

isfile

import os
os.path.isfile(path)

from the docs:

os.path.isfile(path)

Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.

But if you examine the source of this function, you'll see it actually does use a try statement:

# This follows symbolic links, so both islink() and isdir() can be true
# for the same path on systems that support symlinks
def isfile(path):
    """Test whether a path is a regular file"""
    try:
        st = os.stat(path)
    except os.error:
        return False
    return stat.S_ISREG(st.st_mode)

>>> OSError is os.error
True

All it's doing is using the given path to see if it can get stats on it, catching OSError and then checking if it's a file if it didn't raise the exception.

If you intend to do something with the file, I would suggest directly attempting it with a try-except to avoid a race condition:

try:
    with open(path) as f:
        f.read()
except OSError:
    pass

os.access

Available for Unix and Windows is os.access, but to use you must pass flags, and it does not differentiate between files and directories. This is more used to test if the real invoking user has access in an elevated privilege environment:

import os
os.access(path, os.F_OK)

It also suffers from the same race condition problems as isfile. From the docs:

Note: Using access() to check if a user is authorized to e.g. open a file before actually doing so using open() creates a security hole, because the user might exploit the short time interval between checking and opening the file to manipulate it. It’s preferable to use EAFP techniques. For example:

if os.access("myfile", os.R_OK):
    with open("myfile") as fp:
        return fp.read()
return "some default data"

is better written as:

try:
    fp = open("myfile")
except IOError as e:
    if e.errno == errno.EACCES:
        return "some default data"
    # Not a permission error.
    raise
else:
    with fp:
        return fp.read()

Avoid using os.access. It is a low level function that has more opportunities for user error than the higher level objects and functions discussed above.

Criticism of another answer:

Another answer says this about os.access:

Personally, I prefer this one because under the hood, it calls native APIs (via "${PYTHON_SRC_DIR}/Modules/posixmodule.c"), but it also opens a gate for possible user errors, and it's not as Pythonic as other variants:

This answer says it prefers a non-Pythonic, error-prone method, with no justification. It seems to encourage users to use low-level APIs without understanding them.

It also creates a context manager which, by unconditionally returning True, allows all Exceptions (including KeyboardInterrupt and SystemExit!) to pass silently, which is a good way to hide bugs.

This seems to encourage users to adopt poor practices.

if you do not wish to change the eclipse directory, then start eclipse as administrator (right click run as administrator) and install the feature again. it worked for me.

What are the differences between the assignment operators = and <- in R?

As your example shows, = and <- have slightly different operator precedence (which determines the order of evaluation when they are mixed in the same expression). In fact, ?Syntax in R gives the following operator precedence table, from highest to lowest:

…
‘-> ->>’           rightwards assignment
‘<- <<-’           assignment (right to left)
‘=’                assignment (right to left)
…

But is this the only difference?

Since you were asking about the assignment operators: yes, that is the only difference. However, you would be forgiven for believing otherwise. Even the R documentation of ?assignOps claims that there are more differences:

The operator <- can be used anywhere, whereas the operator = is only allowed at the top level (e.g., in the complete expression typed at the command prompt) or as one of the subexpressions in a braced list of expressions.

Let’s not put too fine a point on it: the R documentation is wrong. This is easy to show: we just need to find a counter-example of the = operator that isn’t (a) at the top level, nor (b) a subexpression in a braced list of expressions (i.e. {…; …}). — Without further ado:

x
# Error: object 'x' not found
sum((x = 1), 2)
# [1] 3
x
# [1] 1

Clearly we’ve performed an assignment, using =, outside of contexts (a) and (b). So, why has the documentation of a core R language feature been wrong for decades?

It’s because in R’s syntax the symbol = has two distinct meanings that get routinely conflated (even by experts, including in the documentation cited above):

1. The first meaning is as an assignment operator. This is all we’ve talked about so far.
2. The second meaning isn’t an operator but rather a syntax token that signals named argument passing in a function call. Unlike the = operator it performs no action at runtime, it merely changes the way an expression is parsed.

So how does R decide whether a given usage of = refers to the operator or to named argument passing? Let’s see.

In any piece of code of the general form …

‹function_name›(‹argname› = ‹value›, …)
‹function_name›(‹args›, ‹argname› = ‹value›, …)

… the = is the token that defines named argument passing: it is not the assignment operator. Furthermore, = is entirely forbidden in some syntactic contexts:

if (‹var› = ‹value›) …
while (‹var› = ‹value›) …
for (‹var› = ‹value› in ‹value2›) …
for (‹var1› in ‹var2› = ‹value›) …

Any of these will raise an error “unexpected '=' in ‹bla›”.

In any other context, = refers to the assignment operator call. In particular, merely putting parentheses around the subexpression makes any of the above (a) valid, and (b) an assignment. For instance, the following performs assignment:

median((x = 1 : 10))

But also:

if (! (nf = length(from))) return()

_{Now you might object that such code is atrocious (and you may be right). But I took this code from the base::file.copy function (replacing <- with =) — it’s a pervasive pattern in much of the core R codebase.}

The original explanation by John Chambers, which the the R documentation is probably based on, actually explains this correctly:

[= assignment is] allowed in only two places in the grammar: at the top level (as a complete program or user-typed expression); and when isolated from surrounding logical structure, by braces or an extra pair of parentheses.

In sum, by default the operators <- and = do the same thing. But either of them can be overridden separately to change its behaviour. By contrast, <- and -> (left-to-right assignment), though syntactically distinct, always call the same function. Overriding one also overrides the other. Knowing this is rarely practical but it can be used for some fun shenanigans.

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

I ran into this error when attempting to install 12c 32x client on Windows 10. "net use \\localhost\c$" worked, but when I substituted "localhost" the computer's "name" (e.g., \\my-computer\c$), I got the "System error 53 ...". Oracle seems to prefer the computer's name.

What fixed it: we temporarily disabled the IPv6 protocol for the computer (our network uses IPv4). How to do this: Control Panel --> Network and Sharing Center --> Change adapter settings --> right click on Ethernet Connection --> Properties --> uncheck "Internet Protocol Version 6 (TCP/IPv6) --> OK. That should disable it. After that, \\my-computer\c$ ran successfully in the command prompt. Then the Oracle installer finally completed and we were able to tnsping the database server.

Just to test it out, we re-enabled IPv6 and restarted the computer. \\my-computer\c$ failed in the cmd prompt, but tnsping still functioned correctly.

I hope this helps somebody in the future.

just to be pythonic :-)

>>> x = ['a1sd','23df','aaa','ccc','rrrr', 'ssss', 'e', '']
>>> [x[i] + x[i+1] for i in range(0,len(x),2)]
['a1sd23df', 'aaaccc', 'rrrrssss', 'e']

in case the you want to be alarmed if the list length is odd you can try:

[x[i] + x[i+1] if not len(x) %2 else 'odd index' for i in range(0,len(x),2)]

Best of Luck

Create a new constraint first and then drop the old one.
That way you ensure that:

• constraints are always in place
• existing rows do not violate new constraints
• no illegal INSERT/UPDATEs are attempted after you drop a constraint and before a new one is applied.

This solution worked for me.

Add these lines in your Manifest application tag

android:largeHeap="true"
android:hardwareAccelerated="false"

    

There are many examples on working with arrays in C# here.

I hope this helps.

Thanks, Damian

Hope this helps for item #2: a) You can sort by total bill then reset the index to this column b) Use palette="Blue" to use this color to scale your chart from light blue to dark blue (if dark blue to light blue then use palette="Blues_d")

import pandas as pd
import seaborn as sns
%matplotlib inline

df=pd.read_csv("https://raw.githubusercontent.com/wesm/pydata-book/master/ch08/tips.csv", sep=',')
groupedvalues=df.groupby('day').sum().reset_index()
groupedvalues=groupedvalues.sort_values('total_bill').reset_index()
g=sns.barplot(x='day',y='tip',data=groupedvalues, palette="Blues")

Easy! after your:

    <font color=\"black\" face=\"arial\" size=\"4\">

add this one:

    <font style="opacity:.6"> 

you just have to change the ".6" for a decimal number between 1 and 0

For completeness, since no-one has suggested it yet. .git/refs/heads/master is a file that contains only one line: the hash of the latest commit on master. So you could just read it from there.

Or, as as command:

cat .git/refs/heads/master

Update:

Note that git now supports storing some head refs in the pack-ref file instead of as a file in the /refs/heads/ folder. https://www.kernel.org/pub/software/scm/git/docs/git-pack-refs.html

Try:

num3 = 100000000000LL;

And BTW, in C++ this is a compiler extension, the standard does not define long long, thats part of C99.

You may try these

 int selectedIndex = myComboBox.getSelectedIndex();

-or-

Object selectedObject = myComboBox.getSelectedItem();

-or-

String selectedValue = myComboBox.getSelectedValue().toString();

With GNU Make, you can use shell and eval to store, run, and assign output from arbitrary command line invocations. The difference between the example below and those which use := is the := assignment happens once (when it is encountered) and for all. Recursively expanded variables set with = are a bit more "lazy"; references to other variables remain until the variable itself is referenced, and the subsequent recursive expansion takes place each time the variable is referenced, which is desirable for making "consistent, callable, snippets". See the manual on setting variables for more info.

# Generate a random number.
# This is not run initially.
GENERATE_ID = $(shell od -vAn -N2 -tu2 < /dev/urandom)

# Generate a random number, and assign it to MY_ID
# This is not run initially.
SET_ID = $(eval MY_ID=$(GENERATE_ID))

# You can use .PHONY to tell make that we aren't building a target output file
.PHONY: mytarget
mytarget:
# This is empty when we begin
    @echo $(MY_ID)
# This recursively expands SET_ID, which calls the shell command and sets MY_ID
    $(SET_ID)
# This will now be a random number
    @echo $(MY_ID)
# Recursively expand SET_ID again, which calls the shell command (again) and sets MY_ID (again)
    $(SET_ID)
# This will now be a different random number
    @echo $(MY_ID)

With previously proposed solutions, I have struggled to get multiple npm commands executed in a loop and get all outputs on the console window.

It finally started to work after I have combined everything from the previous comments, but rearranged the code execution flow.

What I have noticed is that event subscribing was done too late (after the process has already started) and therefore some outputs were not captured.

The code below now does the following:

1. Subscribes to the events, before the process has started, therefore ensuring that no output is missed.
2. Begins reading from outputs as soon as the process is started.

The code has been tested against the deadlocks, although it is synchronous (one process execution at the time) so I cannot guarantee what would happen if this was run in parallel.

    static void RunCommand(string command, string workingDirectory)
    {
        Process process = new Process
        {
            StartInfo = new ProcessStartInfo("cmd.exe", $"/c {command}")
            {
                WorkingDirectory = workingDirectory,
                CreateNoWindow = true,
                UseShellExecute = false,
                RedirectStandardError = true,
                RedirectStandardOutput = true
            }
        };

        process.OutputDataReceived += (object sender, DataReceivedEventArgs e) => Console.WriteLine("output :: " + e.Data);

        process.ErrorDataReceived += (object sender, DataReceivedEventArgs e) => Console.WriteLine("error :: " + e.Data);

        process.Start();
        process.BeginOutputReadLine();
        process.BeginErrorReadLine();
        process.WaitForExit();

        Console.WriteLine("ExitCode: {0}", process.ExitCode);
        process.Close();
    }

I recently found this App called Icon Set Creator in the App Store which is free, without ads, updated on new changes, straight forward and works just fine for every possible icon size in OSX, iOS and WatchOS:

In Icon Set Creator:

1. Drag your image into the view
2. Choose your target platform
3. Export the Icon Set folder

In XCode:

1. Navigate to the Assets.xcassets Folder
2. Delete the pre existing AppIcon
3. Right click -> Import your created Icon-Set as AppIcon and you're done

If you're designing for an iOS device or just webkit, you can do it with no JS whatsoever:

CSS:

@-webkit-keyframes spin {  
from {  
    -webkit-transform: rotate(0deg);  
}  
to {  
    -webkit-transform: rotate(360deg);  
    } 
}

.wheel {
    width:40px;
    height:40px;
    background:url(wheel.png);
    -webkit-animation-name: spin; 
    -webkit-animation-iteration-count: infinite; 
    -webkit-animation-timing-function: linear;
    -webkit-animation-duration: 3s; 
}

This would trigger the animation on load. If you wanted to trigger it on hover, it might look like this:

.wheel {
    width:40px;
    height:40px;
    background:url(wheel.png);
}

.wheel:hover {
    -webkit-animation-name: spin; 
    -webkit-animation-iteration-count: infinite; 
    -webkit-animation-timing-function: ease-in-out;
    -webkit-animation-duration: 3s; 
}

The simplest way is to drop the whole database and create it once again:

drop database db_name
create database db_name

That's all.

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.

Set full screen this way,

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
params.width = metrics.widthPixels;
params.height = metrics.heightPixels;
params.leftMargin = 0;
videoView.setLayoutParams(params);

And back to original size, this way.

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
params.width = (int)(300*metrics.density);
params.height = (int)(250*metrics.density);
params.leftMargin = 30;
videoView.setLayoutParams(params);

Just another solution to resolve Promise from the outside

 class Lock {
        #lock;  // Promise to be resolved (on  release)
        release;  // Release lock
        id;  // Id of lock
        constructor(id) {
            this.id = id
            this.#lock = new Promise((resolve) => {
                this.release = () => {
                    if (resolve) {
                        resolve()
                    } else {
                        Promise.resolve()
                    }
                }
            })
        }
        get() { return this.#lock }
    }

Usage

let lock = new Lock(... some id ...);
...
lock.get().then(()=>{console.log('resolved/released')})
lock.release()  // Excpected 'resolved/released'

If you set the implicit wait of the driver, then call the findElement method on an element you expect to be on the loaded page, the WebDriver will poll for that element until it finds the element or reaches the time out value.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

With the Underscore.js

var arr=['a','a1','b'] _.filter(arr, function(a){ return a.indexOf('a') > -1; })

function GetTableLng(tbl)
  local getN = 0
  for n in pairs(tbl) do 
    getN = getN + 1 
  end
  return getN
end

You're right. There are no other way to get length of table

try with:

tr:last-child td:last-child{
    border:none;
    /*any other style*/
}

this will only affect the very last td element in the table, assuming is the only one (else, you'll just have to identify your table). Though, is very general, and it will adapt to the last TD if you add more content to your table. So if it is a particular case

td:nth-child(5){
    border:none;
}

should be enough.

null is a legal value (and reserved word) in JSON, but some environments do not have a "NULL" object (as opposed to a NULL value) and hence cannot accurately represent the JSON null. So they will sometimes represent it as an empty array.

Whether null is a legal value in that particular element of that particular API is entirely up to the API designer.

If you want to run a single independent queued operation and you’re not concerned with other concurrent operations, you can use the global concurrent queue:

dispatch_queue_t globalConcurrentQueue =
dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)

This will return a concurrent queue with the given priority as outlined in the documentation:

DISPATCH_QUEUE_PRIORITY_HIGH Items dispatched to the queue will run at high priority, i.e. the queue will be scheduled for execution before any default priority or low priority queue.

DISPATCH_QUEUE_PRIORITY_DEFAULT Items dispatched to the queue will run at the default priority, i.e. the queue will be scheduled for execution after all high priority queues have been scheduled, but before any low priority queues have been scheduled.

DISPATCH_QUEUE_PRIORITY_LOW Items dispatched to the queue will run at low priority, i.e. the queue will be scheduled for execution after all default priority and high priority queues have been scheduled.

DISPATCH_QUEUE_PRIORITY_BACKGROUND Items dispatched to the queue will run at background priority, i.e. the queue will be scheduled for execution after all higher priority queues have been scheduled and the system will run items on this queue on a thread with background status as per setpriority(2) (i.e. disk I/O is throttled and the thread’s scheduling priority is set to lowest value).

The return exits the current function, but the iterations keeps on, so you get the "next" item that skips the if and alerts the 4...

If you need to stop the looping, you should just use a plain for loop like so:

$('button').click(function () {
   var arr = [1, 2, 3, 4, 5];
   for(var i = 0; i < arr.length; i++) {
     var n = arr[i]; 
     if (n == 3) {
         break;
      }
      alert(n);
   })
})

I was using spring boot, and for me upgrading the version from 1.4.0.RELEASE to 1.5.6.RELEASE solved this issue.

I know its already accepted, but for thoses like me who look for "remove ALL whitespaces" (not just at the begining and endingof the string):

select SUBSTRING_INDEX('1234 243', ' ', 1);
// returns '1234'

EDIT 2019/6/20 : Yeah, that's not good. The function returns the part of the string since "when the character space occured for the first time". So, I guess that saying this remove the leading and trailling whitespaces and returns the first word :

select SUBSTRING_INDEX(TRIM(' 1234 243'), ' ', 1);

you mentioned that you are running yourcode interactivly on spark-shell so, while doing if no proper value is set for driver-memory or executor memory then spark defaultly assign some value to it, which is based on it's properties file(where default value is being mentioned).

I hope you are aware of the fact that there is one driver(master node) and worker-node(where executors are get created and processed), so basically two types of space is required by the spark program,so if you want to set driver memory then when start spark-shell .

spark-shell --driver-memory "your value" and to set executor memory : spark-shell --executor-memory "your value"

then I think you are good to go with the desired value of the memory that you want your spark-shell to use.

        toast.show();

Apple has changed the rules on this. I read through all the Apple docs and as many of the US export regs as I could find.

My view on this was until recently even using HTTPS for most apps meant Apple would require the export certificate. Some apps such as banking would be OK but for many apps they did not fall into the excempt category which is very, very broad.

However Apple has now introduced a getout under the exempt category for apps that JUST use https. I do not know when they did this but I think it was either Dec 2016 or Jan 2017. We are now submitting our apps without the certificate from the US Govt.

Text Wrap:

The MultiCell is used for print text with multiple lines. It has the same atributes of Cell except for ln and link.

$pdf->MultiCell( 200, 40, $reportSubtitle, 1);

Line Height:

What multiCell does is to spread the given text into multiple cells, this means that the second parameter defines the height of each line (individual cell) and not the height of all cells (collectively).

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

You can read the full documentation here.

In a UDF, write:

 Select Top 1 medianSortColumn from Table T
  Where (Select Count(*) from Table
         Where MedianSortColumn <
           (Select Count(*) From Table) / 2)
  Order By medianSortColumn

CharMatcher.retainFrom can be used, if you're using the Google Guava library:

String s = "A função";
String stripped = CharMatcher.ascii().retainFrom(s);
System.out.println(stripped); // Prints "A funo"

The question comes down to what you're going to do with the files.

Under Windows, any directory with more than 2k files tends to open slowly for me in Explorer. If they're all image files, more than 1k tend to open very slowly in thumbnail view.

At one time, the system-imposed limit was 32,767. It's higher now, but even that is way too many files to handle at one time under most circumstances.

Here is my take on the problem:

from math import sqrt
from itertools import count, islice

def is_prime(n):
    return n > 1 and all(n % i for i in islice(count(2), int(sqrt(n)-1)))

This is a really simple and concise algorithm, and therefore it is not meant to be anything near the fastest or the most optimal primality check algorithm. It has a time complexity of O(sqrt(n)). Head over here to learn more about primality tests done right and their history.

Explanation

I'm gonna give you some insides about that almost esoteric single line of code that will check for prime numbers:

• First of all, using range() in Python 2 is really a bad idea, because it will create a list of numbers, which uses a lot of memory. Using xrange() is better, because it creates a generator, which only needs to memorize the initial arguments you provide, and generates every number on-the-fly. If you're using Python 3, range() has been converted to a generator by default. By the way, this is still not the best solution: trying to call xrange(n) for some n such that n > 231-1 (which is the maximum value for a C long) raises OverflowError. Therefore the best way to create a range generator is to use itertools:

   xrange(2147483647+1) # OverflowError
  
   from itertools import count, islice
  
   count(1)                        # Count from 1 to infinity with step=+1
   islice(count(1), 2147483648)    # Count from 1 to 2^31 with step=+1
   islice(count(1, 3), 2147483648) # Count from 1 to 3*2^31 with step=+3
  

• You do not actually need to go all the way up to n if you want to check if n is a prime number. You can dramatically reduce the tests and only check from 2 to v(n) (square root of n). Here's an example:

  Let's find all the divisors of n = 100, and list them in a table:

   2  x  50 = 100
   4  x  25 = 100
   5  x  20 = 100
  10  x  10 = 100 <-- sqrt(100)
  20  x  5  = 100     
  25  x  4  = 100
  50  x  2  = 100
  

  You will easily notice that, after the square root of n, all the divisors we find were actually already found. For example 20 was already found doing 100/5. The square root of a number is the exact mid-point where the divisors we found begin being duplicated. Therefore, to check if a number is prime, you'll only need to check from 2 to sqrt(n).

• Why sqrt(n)-1 then, and not just sqrt(n)? That's just because the second argument provided to itertools.islice() is the number of iterations to execute. islice(count(a), b) stops after b iterations. That's the reason why:

   for number in islice(count(10), 2):
       print number,
  
   # Will print: 10 11
  
   for number in islice(count(1, 3), 10):
       print number,
  
   # Will print: 1 4 7 10 13 16 19 22 25 28
  

• The function all(...) is the same of the following:

   def all(iterable):
       for element in iterable:
           if not element:
               return False
       return True
  

  It literally checks for all the elements in the iterable, returning False when any of them evaluates to False (which for an integer means only if it's zero). Why do we use it then? First of all, we don't need to use an additional index variable (like we would do using a loop), other than that: just for concision, there's no real need of it, but it looks way less bulky to work with only a single line of code instead of several nested lines.

Extended version

I'm including an "unpacked" version of the is_prime() function, to make it easier to understand and read:

from math import sqrt
from itertools import count, islice

def is_prime(n):
    if n < 2:
        return False

    for number in islice(count(2), int(sqrt(n) - 1)):
        if n % number == 0:
            return False

    return True

The currently chosen best answer is too fuzzy to be reliable.

This feels to me like a fairly safe way to do it:

(Javascript: using jQuery to write it simpler)

$('#form1').submit(doubleSubmit);

function doubleSubmit(e1) {
    e1.preventDefault();
    e1.stopPropagation();
    var post_form1 = $.post($(this).action, $(this).serialize());

    post_form1.done(function(result) {
            // would be nice to show some feedback about the first result here
            $('#form2').submit();
        });
};

Post the first form without changing page, wait for the process to complete. Then post the second form. The second post will change the page, but you might want to have some similar code also for the second form, getting a second deferred object (post_form2?).

I didn't test the code, though.

You're very close already, you just need to return the new object that you want. In this case, the same one except with the launches value incremented by 10:

var rockets = [_x000D_
    { country:'Russia', launches:32 },_x000D_
    { country:'US', launches:23 },_x000D_
    { country:'China', launches:16 },_x000D_
    { country:'Europe(ESA)', launches:7 },_x000D_
    { country:'India', launches:4 },_x000D_
    { country:'Japan', launches:3 }_x000D_
];_x000D_
_x000D_
var launchOptimistic = rockets.map(function(elem) {_x000D_
  return {_x000D_
    country: elem.country,_x000D_
    launches: elem.launches+10,_x000D_
  } _x000D_
});_x000D_
_x000D_
console.log(launchOptimistic);

You can use following code to read file in String from resource folder.

final Resource resource = new ClassPathResource("public.key");
String publicKey = null;
try {
     publicKey = new String(Files.readAllBytes(resource.getFile().toPath()), StandardCharsets.UTF_8);
} catch (IOException e) {
     e.printStackTrace();
}

Demo

Later versions of dataTables have the following language settings (taken from here):

• "infoEmpty" - displayed when there are no records in the table
• "zeroRecords" - displayed when there no records matching the filtering

e.g.

$('#example').DataTable( {
    "language": {
        "infoEmpty": "No records available - Got it?",
    }
});

Note: As the property names do not contain any special characters you can remove the quotes:

$('#example').DataTable( {
    language: {
        infoEmpty: "No records available - Got it?",
    }
});

You can create a scaling factor which is applied to the second geom and right y-axis. This is derived from Sebastian's solution.

library(ggplot2)

scaleFactor <- max(mtcars$cyl) / max(mtcars$hp)

ggplot(mtcars, aes(x=disp)) +
  geom_smooth(aes(y=cyl), method="loess", col="blue") +
  geom_smooth(aes(y=hp * scaleFactor), method="loess", col="red") +
  scale_y_continuous(name="cyl", sec.axis=sec_axis(~./scaleFactor, name="hp")) +
  theme(
    axis.title.y.left=element_text(color="blue"),
    axis.text.y.left=element_text(color="blue"),
    axis.title.y.right=element_text(color="red"),
    axis.text.y.right=element_text(color="red")
  )

Note: using ggplot2 v3.0.0

Click File->Project Structure->SDK Location->JDK Location.

You could also set individual module JDK Version compatibility by going to the Module (below the SDK Location), and edit the Source Compatibility accordingly. (note, this only applies to Android Module).

In JavaScript it has no special significance (no more than a or Q anyway). It is just an uninformative variable name.

In jQuery the variable is assigned a copy of the jQuery function. This function is heavily overloaded and means half a dozen different things depending on what arguments it is passed. In this particular example you are passing it a string that contains a selector, so the function means "Create a jQuery object containing the element with the id Text".

If you look at the chain of exceptions, the problem is

Caused by: org.hibernate.PropertyNotFoundException: Could not find a setter for property salt in class backend.Account

The problem is that the method Account.setSalt() works fine when you create an instance but not when you retrieve an instance from the database. This is because you don't want to create a new salt each time you load an Account.

To fix this, create a method setSalt(long) with visibility private and Hibernate will be able to set the value (just a note, I think it works with Private, but you might need to make it package or protected).

Create a list with as many list elements as you want. Then enclose the list in a div, setting style=column-width and style=column-gap, to match the information in your list elements. Do not set style=columns. Totally responsive list that adapts to screen size. No plugins required.

You can create a new JSONObject like this:

JSONObject merged = new JSONObject();
JSONObject[] objs = new JSONObject[] { Obj1, Obj2 };
for (JSONObject obj : objs) {
    Iterator it = obj.keys();
    while (it.hasNext()) {
        String key = (String)it.next();
        merged.put(key, obj.get(key));
    }
}

With this code, if you have any repeated keys between Obj1 and Obj2 the value in Obj2 will remain. If you want the values in Obj1 to be kept you should invert the order of the array in line 2.

If you are using Bootstrap 3, you can use Florin's method, or use a custom CSS file.

If you use Bootstrap less source instead of processed css files, you can directly change it in bootstrap/less/variables.less.

Find something like:

//** Background color used for `.table-striped`.
@table-bg-accent:               #f9f9f9;

Conceptually there are the two "domains" classes and interfaces. Inside these domains you are always extending, only a class implements an interface, which is kind of "crossing the border". So basically "extends" for interfaces mirrors the behavior for classes. At least I think this is the logic behind. It seems than not everybody agrees with this kind of logic (I find it a little bit contrived myself), and in fact there is no technical reason to have two different keywords at all.

jveitchmichaelis at https://github.com/ContinuumIO/anaconda-issues/issues/223 provided a thorough answer. Here I copied his answer:

The documentation in OpenCV says (hidden away) that you can only write to avi using OpenCV3. Whether that's true or not I've not been able to determine, but I've been unable to write to anything else.

However, OpenCV is mainly a computer vision library, not a video stream, codec and write one. Therefore, the developers tried to keep this part as simple as possible. Due to this OpenCV for video containers supports only the avi extension, its first version.

From: http://docs.opencv.org/3.1.0/d7/d9e/tutorial_video_write.html

My setup: I built OpenCV 3 from source using MSVC 2015, including ffmpeg. I've also downloaded and installed XVID and openh264 from Cisco, which I added to my PATH. I'm running Anaconda Python 3. I also downloaded a recent build of ffmpeg and added the bin folder to my path, though that shouldn't make a difference as its baked into OpenCV.

I'm running in Win 10 64-bit.

This code seems to work fine on my computer. It will generate a video containing random static:

writer = cv2.VideoWriter("output.avi",
cv2.VideoWriter_fourcc(*"MJPG"), 30,(640,480))

for frame in range(1000):
    writer.write(np.random.randint(0, 255, (480,640,3)).astype('uint8'))

writer.release()

Some things I've learned through trial and error:

• Only use '.avi', it's just a container, the codec is the important thing.

• Be careful with specifying frame sizes. In the constructor you need to pass the frame size as (column, row) e.g. 640x480. However the array you pass in, is indexed as (row, column). See in the above example how it's switched?

• If your input image has a different size to the VideoWriter, it will fail (often silently)

• Only pass in 8 bit images, manually cast your arrays if you have to (.astype('uint8'))
• In fact, never mind, just always cast. Even if you load in images using cv2.imread, you need to cast to uint8...
• MJPG will fail if you don't pass in a 3 channel, 8-bit image. I get an assertion failure for this at least.
• XVID also requires a 3 channel image but fails silently if you don't do this.
• H264 seems to be fine with a single channel image
• If you need raw output, say from a machine vision camera, you can use 'DIB '. 'RAW ' or an empty codec sometimes works. Oddly if I use DIB, I get an ffmpeg error, but the video is saved fine. If I use RAW, there isn't an error, but Windows Video player won't open it. All are fine in VLC.

In the end I think the key point is that OpenCV is not designed to be a video capture library - it doesn't even support sound. VideoWriter is useful, but 99% of the time you're better off saving all your images into a folder and using ffmpeg to turn them into a useful video.

The easiest way may be to use plotti.co - the microservice I created exactly for this. It depends on how you get the data, but general usage pattern is including an SVG image into your html like

<object data="http://plotti.co/FSktKOvATQ8H/plot.svg" type="image/svg+xml"/>

and feeding your data in a GET request to your hash (or using a (new Image(1,1)).src=... JavaScript method from same or any other page) like this:

http://plotti.co/FSktKOvATQ8H?d=1,2,3

setting it up locally is also straightforward
