The tool NDepend is quoted as Quality Metric Tools but it is pretty much also a Code violation detection tool. Disclaimer: I am one of the developers of the tool

With NDepend, one can write Code Rule over LINQ Queries (what we call CQLinq). More than 200 CQLinq code rules are proposed by default. The strength of CQLinq is that it is straightforward to write a code rule, and get immediately results. Facilities are proposed to browse matched code elements. For example:

Beside that, NDepend comes with many others static analysis like features. These include:

• Smart Technical Debt Estimation
• Dependency Graph
• Dependency Matrix
• Code Diff capabilities
• NDepend.API that lets write you own static analysis tool. With NDepend.APi we even developed a tool to detect code duplicate (details in this blog post: An Original Algorithm to Find .NET Code Duplicate).

What is Stroke:

The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke.

https://docs.oracle.com/javase/7/docs/api/java/awt/BasicStroke.html

Note that the Stroke setting:

Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(10));

is setting the line width,since BasicStroke(float width):

Constructs a solid BasicStroke with the specified line width and with default values for the cap and join styles.

And, it also effects other methods like Graphics2D.drawLine(int x1, int y1, int x2, int y2) and Graphics2D.drawRect(int x, int y, int width, int height):

The methods of the Graphics2D interface that use the outline Shape returned by a Stroke object include draw and any other methods that are implemented in terms of that method, such as drawLine, drawRect, drawRoundRect, drawOval, drawArc, drawPolyline, and drawPolygon.

One [very] hacky way to do it (I saw it work for version 4.0.3):

var selection = $("#DelegateId").data("select2").selection;
var evt = document.createEvent("UIEvents");
selection._handleClear(evt);
selection.trigger("toggle", {});

• allowClear must be set to true
• an empty option must exist in the select element

I had this problem and then I ran "apache_start.bat" the error in german told me there was a problem with line 51 in httpd-ssl.conf which is

SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5

What I did was comment lines 163 (ssl module) and 522 (httpd-ssl.conf include) in httpd.conf; I don't need ssl for development, so that solved it for me.

Braintree also has an open source PHP library that makes PHP integration pretty easy.

I got the same problem, the height of my menu bar provided by bootstrap was too big, actually i downloaded some wrong bootstrap, finally get rid of it by downloading the orignal bootstrap from this site.. http://getbootstrap.com/2.3.2/ want to use bootstrap in yii( netbeans) follow this tutorial, https://www.youtube.com/watch?v=XH_qG8gphaw... The voice is not present but the steps are slow you can easily understand and implement them. Thanks

1. Make sure adb is up to date
2. Make sure you are using the google usb drivers: http://developer.android.com/tools/extras/oem-usb.html
3. Make sure your ANDROID_SDK_HOME environment variable is set to the correct path

import java.util.Calendar;

Calendar cal = Calendar.getInstance();
int currentHour = cal.get(Calendar.HOUR);
if (currentHour > 10 && currentHour < 18) {
    //then rock on
}

I have a new workaround to come in same result, but, with less code. for Winforms... That's example is in portuguese Follow up step by step

1. Create a contextMenuStrip in your form and create one item
2. Sign one event click (OnCancelarItem_Click) for this contextMenuStrip
3. Create a event 'UserDeletingRow' on gridview and now... you've simulating on key press del from user

   you don't forget to enable delete on the gridview, right?!

and finally...

I was looking for a different answer for the question title, so maybe other people will be too.

To set type as an ObjectId (so you may reference author as the author of book, for example), you may do like:

const Book = mongoose.model('Book', {
  author: {
    type: mongoose.Schema.Types.ObjectId, // here you set the author ID
                                          // from the Author colection, 
                                          // so you can reference it
    required: true
  },
  title: {
    type: String,
    required: true
  }
});

If your Object contains Objects then check if they are null, if it have primitives check for their default values.

for Instance:

Person Object 
name Property with getter and setter

to check if name is not initialized. 

Person p = new Person();
if(p.getName()!=null)

From the Notes of Fred Swartz (fredosaurus) :

There are two types of methods.

• Instance methods are associated with an object and use the instance variables of that object. This is the default.

• Static methods use no instance variables of any object of the class they are defined in. If you define a method to be static, you will be given a rude message by the compiler if you try to access any instance variables. You can access static variables, but except for constants, this is unusual. Static methods typically take all they data from parameters and compute something from those parameters, with no reference to variables. This is typical of methods which do some kind of generic calculation. A good example of this are the many utility methods in the predefined Math class.

Qualifying a static call

From outside the defining class, an instance method is called by prefixing it with an object, which is then passed as an implicit parameter to the instance method, eg, inputTF.setText("");

A static method is called by prefixing it with a class name, eg, Math.max(i,j);. Curiously, it can also be qualified with an object, which will be ignored, but the class of the object will be used.

Example

Here is a typical static method:

class MyUtils {
    . . .
    //================================================= mean
    public static double mean(int[] p) {
        int sum = 0;  // sum of all the elements
        for (int i=0; i<p.length; i++) {
            sum += p[i];
        }
        return ((double)sum) / p.length;
    }//endmethod mean
    . . .
}

The only data this method uses or changes is from parameters (or local variables of course).

Why declare a method static

The above mean() method would work just as well if it wasn't declared static, as long as it was called from within the same class. If called from outside the class and it wasn't declared static, it would have to be qualified (uselessly) with an object. Even when used within the class, there are good reasons to define a method as static when it could be.

• Documentation. Anyone seeing that a method is static will know how to call it (see below). Similarly, any programmer looking at the code will know that a static method can't interact with instance variables, which makes reading and debugging easier.
• Efficiency. A compiler will usually produce slightly more efficient code because no implicit object parameter has to be passed to the method.

Calling static methods

There are two cases.

Called from within the same class

Just write the static method name. Eg:

// Called from inside the MyUtils class
double avgAtt = mean(attendance);

Called from outside the class

If a method (static or instance) is called from another class, something must be given before the method name to specify the class where the method is defined. For instance methods, this is the object that the method will access. For static methods, the class name should be specified. Eg:

// Called from outside the MyUtils class.
double avgAtt = MyUtils.mean(attendance); 

If an object is specified before it, the object value will be ignored and the the class of the object will be used.

Accessing static variables

Altho a static method can't access instance variables, it can access static variables. A common use of static variables is to define "constants". Examples from the Java library are Math.PI or Color.RED. They are qualified with the class name, so you know they are static. Any method, static or not, can access static variables. Instance variables can be accessed only by instance methods.

Alternate Call

What's a little peculiar, and not recommended, is that an object of a class may be used instead of the class name to access static methods. This is bad because it creates the impression that some instance variables in the object are used, but this isn't the case.

LDAPService should contain method like LDAPService.isExists(String userName) use it to prevent NPE to be thrown. If is not - this could be a workaround, but use Logging to post some warning..

I Used Datatable JS plugin for my purpose of exporting an html table data into various formats. With my experience it was very quick, easy to use and configure with minimal coding.

Below is a sample jquery call using datatable plugin, #example is your table id

$(document).ready(function() {
    $('#example').DataTable( {
        dom: 'Bfrtip',
        buttons: [
            'copyHtml5',
            'excelHtml5',
            'csvHtml5',
            'pdfHtml5'
        ]
    } );
} );

Please find the complete example in below datatable reference link :

https://datatables.net/extensions/buttons/examples/html5/simple.html

This is how it looks after configuration( from reference site) :

You need to have following library references in your html ( some can be found in the above reference link)

jquery-1.12.3.js
jquery.dataTables.min.js
dataTables.buttons.min.js
jszip.min.js
pdfmake.min.js
vfs_fonts.js
buttons.html5.min.js

import codecs

decode_hex = codecs.getdecoder("hex_codec")

# for an array
msgs = [decode_hex(msg)[0] for msg in msgs]

# for a string
string = decode_hex(string)[0]

I know it's an old thread, but I had to do something like that for a project and I wanted to share the 2019 solution.

The new dialog API can get params and be used without any javascript.

The params are:

• app_id (Required)
• href The URL of the page you wish to share, in case none has passed will use the current URL.
• hashtag have to have the # symbol for example #amsterdam
• quote text to be shared with the link

You can create an href without any javascript what so ever.

<a href="https://www.facebook.com/dialog/feed?&app_id=APP_ID&link=URI&display=popup&quote=TEXT&hashtag=#HASHTAG" target="_blank">Share</a>

One thing to consider is that Facebook is using Open Graph so in case your OG tags are not set properly you might not get the results you wish for.

Description:

there are 3 steps to run PHP code inside post or page.

1. In functions.php file (in your theme) add new function

2. In functions.php file (in your theme) register new shortcode which call your function:

add_shortcode( 'SHORCODE_NAME', 'FUNCTION_NAME' );

3. use your new shortcode

Example #1: just display text.

In functions:

function simple_function_1() {
    return "Hello World!";
}

add_shortcode( 'own_shortcode1', 'simple_function_1' );

In post/page:

[own_shortcode1]

Effect:

Hello World!

Example #2: use for loop.

In functions:

function simple_function_2() {
    $output = "";
    
    for ($number = 1; $number < 10; $number++) {    
        // Append numbers to the string
        $output .= "$number<br>";
    } 
    
    return "$output";
}

add_shortcode( 'own_shortcode2', 'simple_function_2' );

In post/page:

[own_shortcode2]

Effect:

1
2
3
4
5
6
7
8
9

Example #3: use shortcode with arguments

In functions:

function simple_function_3($name) {
    return "Hello $name";
}

add_shortcode( 'own_shortcode3', 'simple_function_3' );

In post/page:

[own_shortcode3 name="John"]

Effect:

Hello John

Example #3 - without passing arguments

In post/page:

[own_shortcode3]

Effect:

Hello 

I came here looking for the answer and since no one put the command for the oracle Java 11 but only openjava 11 I figured out how to do it on Ubuntu, the syntax is as following:

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java11-installer

To compare character you use the == operator:

if (c == ' ')

Just apply scroll behaviour to all elements with this one-line code:

*{
scroll-behavior: smooth !important;
}

Use scp priv_key.pem source user@host:target if you need to connect using a private key.

or if using pscp then use pscp -i priv_key.ppk source user@host:target

The number of parameters is 7850 because with every hidden unit you have 784 input weights and one weight of connection with bias. This means that every hidden unit gives you 785 parameters. You have 10 units so it sums up to 7850.

The role of this additional bias term is really important. It significantly increases the capacity of your model. You can read details e.g. here Role of Bias in Neural Networks.

Try downloading and installing 32-bit version of Java, and then setting the path :)

If you want to keep the height of the DIV absolute, regardless of the amount of text inside use the following:

overflow: hidden;

For just reading the last element of a slice:

sl[len(sl)-1]

For removing it:

sl = sl[:len(sl)-1]

Key presses for more visual people:

1. Enter Command Mode:
   Escape

2. Move around to the start of the area to indent:
   hjkl↑↓←→

3. Start a block:
   v

4. Move around to the end of the area to indent:
   hjkl↑↓←→

5. (Optional) Type the number of indentation levels you want
   0..9

6. Execute the indentation on the block:

You have a multiple options:

First, you can use kill. But you need the pid of your process, which you can get by using ps, pidof or pgrep.

ps -A  // to get the pid, can be combined with grep
-or-
pidof <name>
-or-
pgrep <name>

kill <pid>

It is possible to kill a process by just knowing the name. Use pkill or killall.

pkill <name>
-or-
killall <name>

All commands send a signal to the process. If the process hung up, it might be neccessary to send a sigkill to the process (this is signal number 9, so the following examples do the same):

pkill -9 <name>
pkill -SIGKILL <name>

You can use this option with kill and killall, too.

Read this article about controlling processes to get more informations about processes in general.

 connectionFactory.setUsername("login");
 connectionFactory.setPassword("password");

Delete the java.exe process in Task Manager and re-execute.It worked for me.

You can't without an iteration.

Option 1

Carnet findCarnet(String codeIsIn) {
    for(Carnet carnet : listCarnet) {
        if(carnet.getCodeIsIn().equals(codeIsIn)) {
            return carnet;
        }
    }
    return null;
}

Option 2

Override the equals() method of Carnet.

Option 3

Storing your List as a Map instead, using codeIsIn as the key:

HashMap<String, Carnet> carnets = new HashMap<>();
// setting map
Carnet carnet = carnets.get(codeIsIn);

On Android the color can be declared in the following format

#AARRGGBB

AA - is the bit that’s of most interest to us, it stands for alpha channel

RR GG BB - red, green & blue channels respectively

Now in order to add transparency to our color we need to prepend it with hexadecimal value representing the alpha (transparency).

For example if you want to set 80% transparency value to black color (#000000) you need to prepend it with CC, as a result we end up with the following color resource #CC000000.

You can read about it in more detail on my blog https://androidexplained.github.io/android/ui/2020/10/12/hex-color-code-transparency.html

For targeting IE only in my stylesheets, I use this Sass Mixin :

See the MSDN getch docs. Specifically:

The _getch and_getwch functions read a single character from the console without echoing the character. None of these functions can be used to read CTRL+C. When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.

The Python function returns a character. you can use ord() to get an integer value you can test, for example keycode = ord(msvcrt.getch()).

So if you read an 0x00 or 0xE0, read it a second time to get the key code for an arrow or function key. From experimentation, 0x00 precedes F1-F10 (0x3B-0x44) and 0xE0 precedes arrow keys and Ins/Del/Home/End/PageUp/PageDown.

Simple solution is to run this query: mysql -h yourhostname -u username -p databasename < yoursqlfile.sql

And if you want to import with progress bar, try this: pv yoursqlfile.sql | mysql -uxxx -pxxxx databasename

you should change the adb port with this command:

adb reverse tcp:8880 tcp:8880; adb reverse tcp:8081 tcp:8081; adb reverse tcp:8881 tcp:8881

Use \b for word boundaries:

sed -i 's/\boldtext\b/newtext/g' <file>

Thankfully, it's not possible to change the duration of the vibration. The only way to trigger the vibration is to play the kSystemSoundID_Vibrate as you have. If you really want to though, what you can do is to repeat the vibration indefinitely, resulting in a pulsing vibration effect instead of a long continuous one. To do this, you need to register a callback function that will get called when the vibration sound that you play is complete:

 AudioServicesAddSystemSoundCompletion (
        kSystemSoundID_Vibrate,
        NULL,
        NULL,
        MyAudioServicesSystemSoundCompletionProc,
        NULL
    );
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

Then you define your callback function to replay the vibrate sound again:

#pragma mark AudioService callback function prototypes
void MyAudioServicesSystemSoundCompletionProc (
   SystemSoundID  ssID,
   void           *clientData
);

#pragma mark AudioService callback function implementation

// Callback that gets called after we finish buzzing, so we 
// can buzz a second time.
void MyAudioServicesSystemSoundCompletionProc (
   SystemSoundID  ssID,
   void           *clientData
) {
  if (iShouldKeepBuzzing) { // Your logic here...
      AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); 
  } else {
      //Unregister, so we don't get called again...
      AudioServicesRemoveSystemSoundCompletion(kSystemSoundID_Vibrate);
  }  
}

HashMap<Integer,Player> hash = new HashMap<Integer,Player>();
Set keys = hash.keySet();   
Iterator itr = keys.iterator();

while(itr.hasNext()){
    Integer key = itr.next();
    Player objPlayer = (Player) hash.get(key);
    System.out.println("The player "+objPlayer.getName()+" has "+objPlayer.getScore()+" points");
}

You can use this code to print all scores in your format.

I have used Mockito.verify in this way

@UnitTest
public class JUnitServiceTest
{
    @Mock
    private MyCustomService myCustomService;


    @Test
    public void testVerifyMethod()
    {
       Mockito.verify(myCustomService, Mockito.never()).mymethod(parameters); // method will never call (an alternative can be pick to use times(0))
       Mockito.verify(myCustomService, Mockito.times(2)).mymethod(parameters); // method will call for 2 times
       Mockito.verify(myCustomService, Mockito.atLeastOnce()).mymethod(parameters); // method will call atleast 1 time
       Mockito.verify(myCustomService, Mockito.atLeast(2)).mymethod(parameters); // method will call atleast 2 times
       Mockito.verify(myCustomService, Mockito.atMost(3)).mymethod(parameters); // method will call at most 3 times
       Mockito.verify(myCustomService, Mockito.only()).mymethod(parameters); //   no other method called except this
    }
}

The basic questions that differentiate implementations of "CopyStream" are:

• size of the reading buffer
• size of the writes
• Can we use more than one thread (writing while we are reading).

The answers to these questions result in vastly different implementations of CopyStream and are dependent on what kind of streams you have and what you are trying to optimize. The "best" implementation would even need to know what specific hardware the streams were reading and writing to.

Try using getTime (mdn doc) :

var diff = Math.abs(date1.getTime() - date2.getTime()) / 3600000;
if (diff < 18) { /* do something */ }

Using Math.abs() we don't know which date is the smallest. This code is probably more relevant :

var diff = (date1 - date2) / 3600000;
if (diff < 18) { array.push(date1); }

As of Java 7, java.util.logging.SimpleFormatter supports getting its format from a system property, so adding something like this to the JVM command line will cause it to print on one line:

-Djava.util.logging.SimpleFormatter.format='%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS %4$s %2$s %5$s%6$s%n'

Alternatively, you can also add this to your logger.properties:

java.util.logging.SimpleFormatter.format='%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS %4$s %2$s %5$s%6$s%n'

C# just does a shallow copy when it passes by value unless the object in question executes ICloneable (which apparently the List class does not).

What this means is that it copies the List itself, but the references to the objects inside the list remain the same; that is, the pointers continue to reference the same objects as the original List.

If you change the values of the things your new List references, you change the original List also (since it is referencing the same objects). However, you then change what myList references entirely, to a new List, and now only the original List is referencing those integers.

Read the Passing Reference-Type Parameters section from this MSDN article on "Passing Parameters" for more information.

"How do I Clone a Generic List in C#" from StackOverflow talks about how to make a deep copy of a List.

You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task or Task<T>, if you return nothing and you want your method will be run asyncronously you should define your method like this:

private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } 

And in Main method you can't await for DoDownloadAsync, because you can't use await keyword in non-async function, and you can't make Main async. So consider this:

var result = DoDownloadAsync();  Debug.WriteLine("DoDownload done"); result.Wait(); 

do wget -r -l0 www.oldsite.com

Then just find www.oldsite.com would reveal all urls, I believe.

Alternatively, just serve that custom not-found page on every 404 request! I.e. if someone used the wrong link, he would get the page telling that page wasn't found, and making some hints about site's content.

I had the same problem. In my case, macOS doesn't load my SSH keys, but I fix it with:

You should add these styles to a CSS sheet

div .no-padding {
  padding:0;
}

button .full-width{
  width:100%;
  //display:block; //only if you're having issues
}

Then change add the classes to your code

    <button class="btn btn-large btn-block btn-primary full-width" type="button">Block level button</button>
</div>

I haven't tested this and I'm not 100% sure what you want, but I think this will get you close.

In fact it is so 'nothing but' that in SQL 2000 there was a stack overflow bug due to expansion of the IN into ORs when the list contained about 10k entries (yes, there are people writing 10k IN entries...). So you can't use any wildcard matching in it.

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

They say it right there in the documentation for the FPDF constructor:

FPDF([string orientation [, string unit [, mixed size]]])

This is the class constructor. It allows to set up the page size, the orientation and the unit of measure used in all methods (except for font sizes). Parameters ...

size

The size used for pages. It can be either one of the following values (case insensitive):

A3 A4 A5 Letter Legal

or an array containing the width and the height (expressed in the unit given by unit).

They even give an example with custom size:

Example with a custom 100x150 mm page size:

$pdf = new FPDF('P','mm',array(100,150));

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

set shell=CreateObject("Shell.Application")
' shell.ShellExecute "application", "arguments", "path", "verb", window
shell.ShellExecute  "slipery.bat",,"C:\Users\anthony\Desktop\dvx", "runas", 1
set shell=nothing 

It depends where you put this initialisation.

If the array is static as in

char array[100] = {0};

int main(void)
{
...
}

then it is the compiler that reserves the 100 0 bytes in the data segement of the program. In this case you could have omitted the initialiser.

If your array is auto, then it is another story.

int foo(void)
{
char array[100] = {0};
...
}

In this case at every call of the function foo you will have a hidden memset.

The code above is equivalent to

int foo(void)
{ 
char array[100];

memset(array, 0, sizeof(array));
....
}

and if you omit the initializer your array will contain random data (the data of the stack).

If your local array is declared static like in

int foo(void)
{ 
static char array[100] = {0};
...
}

then it is technically the same case as the first one.

>>> points = {'a': (3, 4), 'c': (5, 5), 'b': (1, 2), 'd': (3, 3)}
>>> dict(filter(lambda x: (x[1][0], x[1][1]) < (5, 5), points.items()))

{'a': (3, 4), 'b': (1, 2), 'd': (3, 3)}

ORA-01031: insufficient privileges happens when the object exists in the schema but do not have any access to that object.

ORA-00942: table or view does not exist happens when the object does not exist in the current schema. If the object exists in another schema, you need to access it using .. Still you can get insufficient privileges error if the owner has not given access to the calling schema.

I want to share a simple approach for downloading files with JavaScript (ES6), React and a Spring Boot backend:

1. Spring boot Rest Controller
   

Resource from org.springframework.core.io.Resource

    @SneakyThrows
    @GetMapping("/files/{filename:.+}/{extraVariable}")
    @ResponseBody
    public ResponseEntity<Resource> serveFile(@PathVariable String filename, @PathVariable String extraVariable) {

        Resource file = storageService.loadAsResource(filename, extraVariable);
        return ResponseEntity.ok()
               .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + file.getFilename() + "\"")
               .body(file);
    }

2. React, API call using AXIOS
   

Set the responseType to arraybuffer to specify the type of data contained in the response.

export const DownloadFile = (filename, extraVariable) => {
let url = 'http://localhost:8080/files/' + filename + '/' + extraVariable;
return axios.get(url, { responseType: 'arraybuffer' }).then((response) => {
    return response;
})};

Final step > downloading
with the help of js-file-download you can trigger browser to save data to file as if it was downloaded.

DownloadFile('filename.extension', 'extraVariable').then(
(response) => {
    fileDownload(response.data, filename);
}
, (error) => {
    // ERROR 
});

array1.equals(array2) is the same as array1 == array2, i.e. is it the same array. As @alf points out it's not what most people expect.

Arrays.equals(array1, array2) compares the contents of the arrays.

Similarly array.toString() may not be very useful and you need to use Arrays.toString(array).

I think what you are looking for is:

list(im.getdata())

or, if the image is too big to load entirely into memory, so something like that:

for pixel in iter(im.getdata()):
    print pixel

from PIL documentation:

getdata

im.getdata() => sequence

Returns the contents of an image as a sequence object containing pixel values. The sequence object is flattened, so that values for line one follow directly after the values of line zero, and so on.

Note that the sequence object returned by this method is an internal PIL data type, which only supports certain sequence operations, including iteration and basic sequence access. To convert it to an ordinary sequence (e.g. for printing), use list(im.getdata()).

USING PHP, HTML AND JAVASCRIPT for prompting

Just if someone looking for using php, html and javascript in a single file, the answer below is working for me.. i attached with the used of bootstrap icon "trash" for the link.

<a class="btn btn-danger" href="<?php echo "delete.php?&var=$var"; ?>" onclick="return confirm('Are you sure want to delete this?');"><span class="glyphicon glyphicon-trash"></span></a>

the reason i used php code in the middle is because i cant use it from the beginning..

the code below doesnt work for me:-

echo "<a class='btn btn-danger' href='delete.php?&var=$var' onclick='return confirm('Are you sure want to delete this?');'><span class='glyphicon glyphicon-trash'></span></a>";

and i modified it as in the 1st code then i run as just what i need.. I hope that can i can help someone inneed of my case.

This link has formulas for what you want. Then it's a matter of performance (numerical techniques) if you want it fast.

I think it's worth putting a few timings up here for some perspective.

All timings done on OS-X 10.5.8 with python2.7

John Clement's answer:

python -m timeit -s 'my_list = range(1000)[::-1]; from operator import itemgetter' 'min(enumerate(my_list),key=itemgetter(1))'
1000 loops, best of 3: 239 usec per loop    

David Wolever's answer:

python -m timeit -s 'my_list = range(1000)[::-1]' 'min((val, idx) for (idx, val) in enumerate(my_list))
1000 loops, best of 3: 345 usec per loop

OP's answer:

python -m timeit -s 'my_list = range(1000)[::-1]' 'my_list.index(min(my_list))'
10000 loops, best of 3: 96.8 usec per loop

Note that I'm purposefully putting the smallest item last in the list to make .index as slow as it could possibly be. It would be interesting to see at what N the iterate once answers would become competitive with the iterate twice answer we have here.

Of course, speed isn't everything and most of the time, it's not even worth worrying about ... choose the one that is easiest to read unless this is a performance bottleneck in your code (and then profile on your typical real-world data -- preferably on your target machines).

This might do the trick:

$(document).ready(function() {
    $("input[type=text]").change(function() {
        $(this).data("old", $(this).data("new") || "");
        $(this).data("new", $(this).val());
        console.log($(this).data("old"));
        console.log($(this).data("new"));
    });
});

What is the best place is your question. The best place is inside the Controller.Initialize method. MSDN writes that it is called after the constructor and before the action method. In contrary of overriding OnActionExecuting, placing your code in the Initialize method allow you to benefit of having all custom data annotation and attribute on your classes and on your properties to be localized.

For example, my localization logic come from an class that is injected to my custom controller. I have access to this object since Initialize is called after the constructor. I can do the Thread's culture assignation and not having every error message displayed correctly.

 public BaseController(IRunningContext runningContext){/*...*/}

 protected override void Initialize(RequestContext requestContext)
 {
     base.Initialize(requestContext);
     var culture = runningContext.GetCulture();
     Thread.CurrentThread.CurrentUICulture = culture;
     Thread.CurrentThread.CurrentCulture = culture;
 }

Even if your logic is not inside a class like the example I provided, you have access to the RequestContext which allow you to have the URL and HttpContext and the RouteData which you can do basically any parsing possible.

In intellij you can auto generate toString method by pressing alt+inset and then selecting toString() here is an out put for a test class:

public class test  {
int a;
char b;
String c;
Test2 test2;

@Override
public String toString() {
    return "test{" +
            "a=" + a +
            ", b=" + b +
            ", c='" + c + '\'' +
            ", test2=" + test2 +
            '}';
 }
}

As you can see, it generates a String by concatenating, several attributes of the class, for primitives it will print their values and for reference types it will use their class type (in this case to string method of Test2).

You can use the strdup function which has the following prototype

char *strdup(const char *s1);

Example of use:

#include <string.h>

char * my_str = strdup("My string literal!");
char * my_other_str = strdup(some_const_str);

or strcpy/strncpy to your buffer

or rewrite your functions to use const char * as parameter instead of char * where possible so you can preserve the const

Well, to get rid of this you need to set phpMyadmin variable to either 0 that is unlimited or whichever value in seconds you find suitable for your needs. Or you could always use CLI(command line interface) to not even get such errors(For which you would like to take a look at this link.

Now about the error here, first on the safe side make sure you have set PHP parameters properly so that you can upload large files and can use maximum execution time from that end. If not, go ahead and set below three parameters from php.ini file,

1. max_execution_time=3000000 (Set this as per your req)
2. post_max_size=4096M
3. upload_max_filesize=4096M

Once that's done get back to finding phpMyadmin config file named something like "config.default.php". On XAMPP you will find it under "C:\xampp\phpMyAdmin\libraries" folder. Open the file called config.default.php and set :

$cfg['ExecTimeLimit'] = 0;

Once set, restart your MySQL and Apache and go import your database.

If you are searching literally the way to return a JSON list in flask and you are completly sure that your variable is a list then the easy way is (where bin is a list of 1's and 0's):

   return jsonify({'ans':bin}), 201

Finally, in your client you will obtain something like

{ "ans": [ 0.0, 0.0, 1.0, 1.0, 0.0 ] }

Follow the below steps:

1. No need to give any type of header.

2. Select body > form-data and do same as shown in the image.

3. Now in your Django view.py

def post(self, request, *args, **kwargs):
    image = request.FILES["image"]
    data = json.loads(request.data['data'])
    ...
    return Response(...)

4. You can access all the keys (id, uid etc..) from the data variable.

I stumbled over this thread searching for answer to similar case. Basically all answers are found, but it's still hard to extract the essentials from them.

Kinds of Access

Assume a class Foo probably derived from some other class(es) with probably more classes derived from it.

Then accessing

• from static method/getter of Foo
  • some probably overridden static method/getter:
    • this.method()
    • this.property
  • some probably overridden instance method/getter:
    • impossible by design
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • impossible by design
• from instance method/getter of Foo
  • some probably overridden static method/getter:
    • this.constructor.method()
    • this.constructor.property
  • some probably overridden instance method/getter:
    • this.method()
    • this.property
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • not possible by intention unless using some workaround:
      • Foo.prototype.method.call( this )
      • Object.getOwnPropertyDescriptor( Foo.prototype,"property" ).get.call(this);

Keep in mind that using this isn't working this way when using arrow functions or invoking methods/getters explicitly bound to custom value.

Background

• When in context of an instance's method or getter
  • this is referring to current instance.
  • super is basically referring to same instance, but somewhat addressing methods and getters written in context of some class current one is extending (by using the prototype of Foo's prototype).
  • definition of instance's class used on creating it is available per this.constructor.
• When in context of a static method or getter there is no "current instance" by intention and so
  • this is available to refer to the definition of current class directly.
  • super is not referring to some instance either, but to static methods and getters written in context of some class current one is extending.

Don't.

Use a regex for a quick sanity check, something like .@.., but almost all langauges / frameworks have better methods for checking an e-mail address. Use that.

It is possible to validate an e-mail address with a regex, but it is a long regex. Very long.
And in the end you will be none the wiser. You'll only know that the format is valid, but you still don't know if it's an active e-mail address. The only way to find out, is by sending a confirmation e-mail.

UTF-8 is supposed to handle all accents and foreign chars - why not use it on your data source?

EDIT
[Archive copy of the test file.] with your data

Everything should be UTF-8 in the first place. I loaded the files in notepad++, converted to utf-8 and manually changed the charactes to accents were needed. Once done everything's working like a charm.

BTW, unless your server is defined to php-process .html files, the files you're loading with ajax aren't getting your iso charset. If you insist on using the iso charset, request a php file instead of an html file, and define the charset in the header (not in the file itself)

Overall, the conventions are “think like you're just delivering web pages”.

For a PUT, I'd return the same view that you'd get if you did a GET immediately after; that would result in a 200 (well, assuming the rendering succeeds of course). For a POST, I'd do a redirect to the resource created (assuming you're doing a creation operation; if not, just return the results); the code for a successful create is a 201, which is really the only HTTP code for a redirect that isn't in the 300 range.

I've never been happy about what a DELETE should return (my code currently produces an HTTP 204 and an empty body in this case).

you should know that :

@Before from junit4 goes with @Test : "import org.junit.Test"

AND

@BeforeEach from Junit5 goes with : "import org.junit.jupiter.api.Test"

so make sure you are using the imports from the same version of Junit , otherwise it w'ont Work I guess.

My project is built in Yii & uses the Bootstrap-Yii plugin, so this answer is only relevant if you're using Yii.

The above fix did work but only after the first time the modal was shown. The first time it came up empty. I think that's because after my initiation of the code Yii calls the hide function of the modal thereby clearing out my initiation variables.

I found that putting the removeData call immediately before the code that launched the modal did the trick. So my code is structured like this...

$ ("#myModal").removeData ('modal');
$ ('#myModal').modal ({remote : 'path_to_remote'});

I like @huynhjl's answer, it led me down the right path. However, it isn't great at handling error conditions. If the desired node does not exist, you get a cast exception. I've adapted this slightly to make use of Option to better handle this.

class CC[T] {
  def unapply(a:Option[Any]):Option[T] = if (a.isEmpty) {
    None
  } else {
    Some(a.get.asInstanceOf[T])
  }
}

object M extends CC[Map[String, Any]]
object L extends CC[List[Any]]
object S extends CC[String]
object D extends CC[Double]
object B extends CC[Boolean]

for {
  M(map) <- List(JSON.parseFull(jsonString))
  L(languages) = map.get("languages")
  language <- languages
  M(lang) = Some(language)
  S(name) = lang.get("name")
  B(active) = lang.get("is_active")
  D(completeness) = lang.get("completeness")
} yield {
  (name, active, completeness)
}

Of course, this doesn't handle errors so much as avoid them. This will yield an empty list if any of the json nodes are missing. You can use a match to check for the presence of a node before acting...

for {
  M(map) <- Some(JSON.parseFull(jsonString))
} yield {
  map.get("languages") match {
    case L(languages) => {
      for {
        language <- languages
        M(lang) = Some(language)
        S(name) = lang.get("name")
        B(active) = lang.get("is_active")
        D(completeness) = lang.get("completeness")
      } yield {
        (name, active, completeness)
      }        
    }
    case None => "bad json"
  }
}

Easiest way would be to use the serialize function.

It serializes any variable for storage or transfer. You can read about it in the php manual - serialize

The variable can be restored by using unserialize

So in the passing to the URL you use:

$url = urlencode(serialize($array))

and to restore the variable you use

$var = unserialize(urldecode($_GET['array']))

Be careful here though. The maximum size of a GET request is limited to 4k, which you can easily exceed by passing arrays in a URL.

Also, its really not quite the safest way to pass data! You should probably look into using sessions instead.

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

I think I identified the root cause: I have switched the default Apple ID account and the new one was not activated as a Developer account. When I ran the xcode-select --install command, I got the same error as stated in the issue description.

After reading this post on stackoverflow, I went on https://developer.apple.com/downloads and I was asked to accept Developers terms. I think it enabled my account as a developer one. Then, I tried to run xcode-select --install again and it worked.

This might be off-topic. But for the wget in for loop, you can certainly do

curl -O http://example.com/search/link[1-600]

I just wanted to chime in that I hit this after updating Android Studio components.

What worked for me was to open gradle-wrapper.properties and update the gradle version used. As of now for my projects the line reads:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip

I guess best way to do this is ...

int main()
{
    char str[100];
    scanf("[^EOF]",str);
    printf("%s",str);
    return 0;     
}

For all those who don't have the option in Excel (like me), there is a macro which works and is explained here: https://www.get-digital-help.com/2015/08/03/custom-data-labels-in-x-y-scatter-chart/ Very useful

Component template should contain exactly one root element. If you are using v-if on multiple elements, use v-else-if to chain them instead.

The right approach is

<template>
  <div> <!-- The root -->
    <p></p> 
    <p></p>
  </div>
</template>

The wrong approach

<template> <!-- No root Element -->
    <p></p> 
    <p></p>
</template>

Multi Root Components

The way around to that problem is using functional components, they are components where you have to pass no reactive data means component will not be watching for any data changes as well as not updating it self when something in parent component changes.

As this is a work around it comes with a price, functional components don't have any life cycle hooks passed to it, they are instance less as well you cannot refer to this anymore and everything is passed with context.

Here is how you can create a simple functional component.

Vue.component('my-component', {
    // you must set functional as true
  functional: true,
  // Props are optional
  props: {
    // ...
  },
  // To compensate for the lack of an instance,
  // we are now provided a 2nd context argument.
  render: function (createElement, context) {
    // ...
  }
})

Now that we have covered functional components in some detail lets cover how to create multi root components, for that I am gonna present you with a generic example.

<template>
 <ul>
     <NavBarRoutes :routes="persistentNavRoutes"/>
     <NavBarRoutes v-if="loggedIn" :routes="loggedInNavRoutes" />
     <NavBarRoutes v-else :routes="loggedOutNavRoutes" />
 </ul>
</template>

Now if we take a look at NavBarRoutes template

<template>
 <li
 v-for="route in routes"
 :key="route.name"
 >
 <router-link :to="route">
 {{ route.title }}
 </router-link>
 </li>
</template>

We cant do some thing like this we will be violating single root component restriction

Solution Make this component functional and use render

{
functional: true,
render(h, { props }) {
 return props.routes.map(route =>
  <li key={route.name}>
    <router-link to={route}>
      {route.title}
    </router-link>
  </li>
 )
}

Here you have it you have created a multi root component, Happy coding

Enable Multidex through build.gradle of your app module

multiDexEnabled true

Same as below -

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

Then follow below steps -

1. From the Build menu -> press the Clean Project button.
2. When task completed, press the Rebuild Project button from the Build menu.
3. From menu File -> Invalidate cashes / Restart

compile is now deprecated so it's better to use implementation or api

You can also use

$('#myModal').hasClass('show');

Very easy code. You keep appending the path each time you discover a node.

graph = {
         'A': set(['B', 'C']),
         'B': set(['A', 'D', 'E']),
         'C': set(['A', 'F']),
         'D': set(['B']),
         'E': set(['B', 'F']),
         'F': set(['C', 'E'])
         }
def retunShortestPath(graph, start, end):

    queue = [(start,[start])]
    visited = set()

    while queue:
        vertex, path = queue.pop(0)
        visited.add(vertex)
        for node in graph[vertex]:
            if node == end:
                return path + [end]
            else:
                if node not in visited:
                    visited.add(node)
                    queue.append((node, path + [node]))

Use ==:

pip install django_modeltranslation==0.4.0-beta2

The scoping is correct as you've noted. However, you are not calling the inner function anywhere.

You can do either:

function outer() { 

    // when you define it this way, the inner function will be accessible only from 
    // inside the outer function

    function inner() {
        alert("hi");
    }
    inner(); // call it
}

Or

function outer() { 
    this.inner = function() {
        alert("hi");
    }
}

<input type="button" onclick="(new outer()).inner();" value="ACTION">?

Most likely these classes are already defined by Bootstrap, make sure that your CSS file that you want to override the classes with is called AFTER the Bootstrap CSS.

<link rel="stylesheet" href="css/bootstrap.css" /> <!-- Call Bootstrap first -->
<link rel="stylesheet" href="css/bootstrap-override.css" /> <!-- Call override CSS second -->

Otherwise, you can put !important at the end of your CSS like this: color:#ffffff!important; but I would advise against using !important at all costs.

Here's a simple function that flattens lists of arbitrary depth. No recursion, to avoid stack overflow.

from copy import deepcopy

def flatten_list(nested_list):
    """Flatten an arbitrarily nested list, without recursion (to avoid
    stack overflows). Returns a new list, the original list is unchanged.

    >> list(flatten_list([1, 2, 3, [4], [], [[[[[[[[[5]]]]]]]]]]))
    [1, 2, 3, 4, 5]
    >> list(flatten_list([[1, 2], 3]))
    [1, 2, 3]

    """
    nested_list = deepcopy(nested_list)

    while nested_list:
        sublist = nested_list.pop(0)

        if isinstance(sublist, list):
            nested_list = sublist + nested_list
        else:
            yield sublist

I am surprised that this question has been around for so long and nobody has as yet provided an answer based on Roy Osherove's "The Art of Unit Testing".

In "3.1 Introducing stubs" defines a stub as:

A stub is a controllable replacement for an existing dependency (or collaborator) in the system. By using a stub, you can test your code without dealing with the dependency directly.

And defines the difference between stubs and mocks as:

The main thing to remember about mocks versus stubs is that mocks are just like stubs, but you assert against the mock object, whereas you do not assert against a stub.

Fake is just the name used for both stubs and mocks. For example when you don't care about the distinction between stubs and mocks.

The way Osherove's distinguishes between stubs and mocks, means that any class used as a fake for testing can be both a stub or a mock. Which it is for a specific test depends entirely on how you write the checks in your test.

• When your test checks values in the class under test, or actually anywhere but the fake, the fake was used as a stub. It just provided values for the class under test to use, either directly through values returned by calls on it or indirectly through causing side effects (in some state) as a result of calls on it.
• When your test checks values of the fake, it was used as a mock.

Example of a test where class FakeX is used as a stub:

const pleaseReturn5 = 5;
var fake = new FakeX(pleaseReturn5);
var cut = new ClassUnderTest(fake);

cut.SquareIt;

Assert.AreEqual(25, cut.SomeProperty);

The fake instance is used as a stub because the Assert doesn't use fake at all.

Example of a test where test class X is used as a mock:

const pleaseReturn5 = 5;
var fake = new FakeX(pleaseReturn5);
var cut = new ClassUnderTest(fake);

cut.SquareIt;

Assert.AreEqual(25, fake.SomeProperty);

In this case the Assert checks a value on fake, making that fake a mock.

Now, of course these examples are highly contrived, but I see great merit in this distinction. It makes you aware of how you are testing your stuff and where the dependencies of your test are.

I agree with Osherove's that

from a pure maintainability perspective, in my tests using mocks creates more trouble than not using them. That has been my experience, but I’m always learning something new.

Asserting against the fake is something you really want to avoid as it makes your tests highly dependent upon the implementation of a class that isn't the one under test at all. Which means that the tests for class ActualClassUnderTest can start breaking because the implementation for ClassUsedAsMock changed. And that sends up a foul smell to me. Tests for ActualClassUnderTest should preferably only break when ActualClassUnderTest is changed.

I realize that writing asserts against the fake is a common practice, especially when you are a mockist type of TDD subscriber. I guess I am firmly with Martin Fowler in the classicist camp (See Martin Fowler's "Mocks aren't Stubs") and like Osherove avoid interaction testing (which can only be done by asserting against the fake) as much as possible.

For fun reading on why you should avoid mocks as defined here, google for "fowler mockist classicist". You'll find a plethora of opinions.

Try this

select convert(varchar,getdate(),100)

third parameter is format, range is from 100 to 114, any one should work for you.

If you need date in dd/mmm/yyyy use this:

replace(convert(char(11),getdate(),113),' ','-')

Replace getdate() with your column name. This worked for me.

Quote from The Swift Programming Language, which answers your question:

“Swift’s compiler performs four helpful safety-checks to make sure that two-phase initialization is completed without error:”

Safety check 1 “A designated initializer must ensure that all of the “properties introduced by its class are initialized before it delegates up to a superclass initializer.”

My solution is simple. I am using [href] instead of [routerLink]. I have tried all solutions for [routerLink]. None of them works in my case.

Here is my solution:

<a [href]="getPlanUrl()" target="_blank">My Plan Name</a>

Then write the getPlanUrl function in the TS file.

In addition to Rufinus' reply, the shortcut to copy your ssh key to the clipboard in Windows is:

• type id_rsa.pub | clip

Refs:

• Print to standard output
• Copy command line output to clipboard

Beware that file_get_contents solution doesn't close the connection as it should when a server returns Connection: close in the HTTP header.

CURL solution, on the other hand, terminates the connection so the PHP script is not blocked by waiting for a response.

from bs4 import BeautifulSoup
from selenium import webdriver

driver = webdriver.Chrome()
html_source_code = driver.execute_script("return document.body.innerHTML;")
html_soup: BeautifulSoup = BeautifulSoup(html_source_code, 'html.parser')

Now you can apply BeautifulSoup function to extract data...

I got the same error due to it being a conflict with miniconda3 install so when you type "which virtualenv" and if you've installed miniconda and it's pointing to that install you can either remove it (if your like me and haven't moved to it yet) or change your environment variable to point to the install you want.

If a pipeline is too complicated to wrap in $(...), consider writing a function. Any local variables available at the time of definition will be accessible.

function getHash {
  genhash --use-ssl -s $IP -p 443 --url $URL | grep MD5 | grep -c $MD5
}
hash=$(getHash)

If you want to get stored procedures using specific column only, you can use try this query:

SELECT DISTINCT Name
FROM sys.Procedures
WHERE object_definition(OBJECT_ID) LIKE '%CreatedDate%';

If you want to get stored procedures using specific column of table, you can use below query :

SELECT DISTINCT Name 
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%';

at least pip3 also works without "=", however, instead of "http" you might need "https"

Final command, which worked for me:

sudo pip3 install --proxy https://{proxy}:{port} {BINARY}

There is an option in search => file and shortcut is Ctrl+H. Go for further refer follow link. This is work fine with Eclipse Neon

Is there a way to find/replace across an entire project in Eclipse?

In the code you have posted there would be no advantages, as you are misusing the StringBuilder. You build the same String in both cases. Using StringBuilder you can avoid the + operation on Strings using the append method. You should use it this way:

return new StringBuilder("select id1, ").append(" id2 ").append(" from ").append(" table").toString();

In Java, the String type is an inmutable sequence of characters, so when you add two Strings the VM creates a new String value with both operands concatenated.

StringBuilder provides a mutable sequence of characters, which you can use to concat different values or variables without creating new String objects, and so it can sometimes be more efficient than working with strings

This provides some useful features, as changing the content of a char sequence passed as parameter inside another method, which you can't do with Strings.

private void addWhereClause(StringBuilder sql, String column, String value) {
   //WARNING: only as an example, never append directly a value to a SQL String, or you'll be exposed to SQL Injection
   sql.append(" where ").append(column).append(" = ").append(value);
}

The question is a bit unclear can't you just repeat the for loop?

a=[1,2,3]

for i in a:
    print i
1
2
3


for i in a:
    print i
1
2
3

Use this code, Working properly

CREATE PROCEDURE [dbo].[sp_delete_item]
@ItemId int = 0
@status bit OUT

AS
Begin
 DECLARE @cnt int;
 DECLARE @status int =0;
 SET NOCOUNT OFF
 SELECT @cnt =COUNT(Id) from ItemTransaction where ItemId = @ItemId
 if(@cnt = 1)
   Begin
     return @status;
   End
 else
  Begin
   SET @status =1;
    return @status;
 End
END

Execute SP

DECLARE @statuss bit;
EXECUTE  [dbo].[sp_delete_item] 6, @statuss output;
PRINT @statuss;

Here's my variant:

  with_env() {
    (set -a && . ./.env && "$@")
  }

compared with the previous solutions:

• it does not leak variables outside scope (values from .env are not exposed to caller)
• does not clobber set options
• returns exit code of the executed command
• uses posix compatible set -a
• uses . instead of source to avoid bashism
• command is not invoked if .env loading fails

with_env rails console

Well, since 'X' is a char and not an int, you cannot actually replace it in the matrix itself, however, the following code should print an 'x' char whenever it comes across a 1.

public void printGrid(int[][] in){  
    for(int i = 0; i < 20; i++){  
        for(int j = 0; j < 20; j++){  
            if(in[i][j] == 1)  
                System.out.print('X' + "\t");
            else
                System.out.print(in[i][j] + "\t");
        }
        System.out.print("\n");
    }
}

I know you asked how to disable console.log, but this might be what you're really after. This way you don't have to explicitly enable or disable the console. It simply prevents those pesky console errors for people who don't have it open or installed.

if(typeof(console) === 'undefined') {
    var console = {};
    console.log = console.error = console.info = console.debug = console.warn = console.trace = console.dir = console.dirxml = console.group = console.groupEnd = console.time = console.timeEnd = console.assert = console.profile = function() {};
}

To have a query working in any locale settings, consider formatting the date yourself:

SELECT * 
  FROM testbed 
 WHERE start_date >= to_date('2012-01-01','YYYY-MM-DD')
   AND end_date <= to_date('2012-04-13','YYYY-MM-DD');

I'd like to add a new version of flatten case (this is what i needed :)) which, according to my probes with the above jsFiddler, is slightly faster then the currently selected one. Moreover, me personally see this snippet a bit more readable, which is of course important for multi-developer projects.

function flattenObject(graph) {
    let result = {},
        item,
        key;

    function recurr(graph, path) {
        if (Array.isArray(graph)) {
            graph.forEach(function (itm, idx) {
                key = path + '[' + idx + ']';
                if (itm && typeof itm === 'object') {
                    recurr(itm, key);
                } else {
                    result[key] = itm;
                }
            });
        } else {
            Reflect.ownKeys(graph).forEach(function (p) {
                key = path + '.' + p;
                item = graph[p];
                if (item && typeof item === 'object') {
                    recurr(item, key);
                } else {
                    result[key] = item;
                }
            });
        }
    }
    recurr(graph, '');

    return result;
}

I don't know if this is efficient as others but simple logic always works:

import sys
name = ["Sam", "Peter", "James", "Julian", "Ann"]
for i in range(0, len(names)):
    sys.stdout.write(names[i])
    if i != len(names)-1:
        sys.stdout.write(", ")

Output:

Sam, Peter, James, Julian, Ann

I use EasyGit (a.k.a. "eg") as a super lightweight wrapper on top of (or along side of) Git. EasyGit has an "info" subcommand that gives you all kinds of super useful information, including the current branches remote tracking branch. Here's an example (where the current branch name is "foo"):

I wrote telegram bot, and have some problem with update rows. Use this example, if you have Model

def update_state(chat_id, state):
    try:
        value = Users.query.filter(Users.chat_id == str(chat_id)).first()
        value.state = str(state)
        db.session.flush()
        db.session.commit()
        #db.session.close()
    except:
        print('Error in def update_state')

Why use db.session.flush()? That's why >>> SQLAlchemy: What's the difference between flush() and commit()?

Comparaison of the different methods:

> CGI::escapeHTML("quote ' double quotes \"")
=> "quote ' double quotes ""

> Rack::Utils.escape_html("quote ' double quotes \"")

I wrote my own to be compatible with Rails ActiveMailer escaping:

i did try this and its working in windows machine to run a sql file on a specific schema.

psql -h localhost -p 5432 -U username -d databasename -v schema=schemaname < e:\Table.sql

Try:

EditText edt = (EditText) findViewById(R.id.YourEditText);
RelativeLayout.LayoutParams lp =
    new RelativeLayout.LayoutParams
    (
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
    );
lp.setMargins(25, 0, 0, 0); // move 25 px to right (increase left margin)
edt.setLayoutParams(lp); // lp.setMargins(left, top, right, bottom);

You might also consider trying one of these approaches, since larger tables aren't exactly friendly on mobile even if it works:

I'm partial to 'No More Tables' but that obviously depends on your application.

After inspecting the sample website you provided, I found that the author might achieve the effect by using a library called Stellar.js, take a look at the library site, cheers!

Assuming you have a button with the id button, try this example:

$("#button").click(function() {
    $([document.documentElement, document.body]).animate({
        scrollTop: $("#elementtoScrollToID").offset().top
    }, 2000);
});

I got the code from the article Smoothly scroll to an element without a jQuery plugin. And I have tested it on the example below.

<html>_x000D_
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>_x000D_
    <script>_x000D_
        $(document).ready(function (){_x000D_
            $("#click").click(function (){_x000D_
                $('html, body').animate({_x000D_
                    scrollTop: $("#div1").offset().top_x000D_
                }, 2000);_x000D_

A modified version to compensate network times and calculate with DateTime-Ticks (more precise than milliseconds)

public static DateTime GetNetworkTime()
{
  const string NtpServer = "pool.ntp.org";

  const int DaysTo1900 = 1900 * 365 + 95; // 95 = offset for leap-years etc.
  const long TicksPerSecond = 10000000L;
  const long TicksPerDay = 24 * 60 * 60 * TicksPerSecond;
  const long TicksTo1900 = DaysTo1900 * TicksPerDay;

  var ntpData = new byte[48];
  ntpData[0] = 0x1B; // LeapIndicator = 0 (no warning), VersionNum = 3 (IPv4 only), Mode = 3 (Client Mode)

  var addresses = Dns.GetHostEntry(NtpServer).AddressList;
  var ipEndPoint = new IPEndPoint(addresses[0], 123);
  long pingDuration = Stopwatch.GetTimestamp(); // temp access (JIT-Compiler need some time at first call)
  using (var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp))
  {
    socket.Connect(ipEndPoint);
    socket.ReceiveTimeout = 5000;
    socket.Send(ntpData);
    pingDuration = Stopwatch.GetTimestamp(); // after Send-Method to reduce WinSocket API-Call time

    socket.Receive(ntpData);
    pingDuration = Stopwatch.GetTimestamp() - pingDuration;
  }

  long pingTicks = pingDuration * TicksPerSecond / Stopwatch.Frequency;

  // optional: display response-time
  // Console.WriteLine("{0:N2} ms", new TimeSpan(pingTicks).TotalMilliseconds);

  long intPart = (long)ntpData[40] << 24 | (long)ntpData[41] << 16 | (long)ntpData[42] << 8 | ntpData[43];
  long fractPart = (long)ntpData[44] << 24 | (long)ntpData[45] << 16 | (long)ntpData[46] << 8 | ntpData[47];
  long netTicks = intPart * TicksPerSecond + (fractPart * TicksPerSecond >> 32);

  var networkDateTime = new DateTime(TicksTo1900 + netTicks + pingTicks / 2);

  return networkDateTime.ToLocalTime(); // without ToLocalTime() = faster
}

The default value can be followed with a : after the property key, e.g.

<property name="port" value="${my.server.port:8080}" />

Or in java code:

@Value("${my.server.port:8080}")
private String myServerPort;

I had this issue and realised that whilst I did have libxml2 installed, I didn't have the necessary development libraries required by the python package. Installing them solved the problem:

sudo apt-get install libxml2-dev libxslt1-dev
sudo pip install lxml

It's also reported on Android bug tracker: https://issuetracker.google.com/issues/79478779

Viewport units for CSS

1vw = 1% of viewport width
1vh = 1% of viewport height

This way, you don't have to write many different media queries or javascript.

If you prefer JS

window.innerWidth;
window.innerHeight;

variable=$(ps -ef | awk '/[p]ort 10/ {print $12}')

The [p] is a neat trick to remove the search from showing from ps

@Jeremy If you post the output of ps -ef | grep "port 10", and what you need from the line, it would be more easy to help you getting correct syntax

Cross browser way

$(window).on('resize orientationchange webkitfullscreenchange mozfullscreenchange fullscreenchange',  function(){
//code here
});

The actual code to cast away the const-ness of your pointer would be:

BoxT<T> * nonConstObj = const_cast<BoxT<T> *>(constObj);

But note that this really is cheating. A better solution would either be to figure out why you want to modify a const object, and redesign your code so you don't have to.... or remove the const declaration from your vector, if it turns out you don't really want those items to be read-only after all.

You can create a list of objects in one line using a list comprehension.

class MyClass(object): pass

objs = [MyClass() for i in range(10)]

print(objs)

Yet another way to use Rscript for *Unix systems is Process Substitution.

Rscript <(zcat a.r)
# [1] "hello"

Which obviously does the same as the accepted answer, but this allows you to manipulate and run your file without saving it the power of the command line, e.g.:

Rscript <(sed s/hello/bye/ a.r)
# [1] "bye"

Similar to Rscript -e "Rcode" it also allows to run without saving into a file. So it could be used in conjunction with scripts that generate R-code, e.g.:

Rscript <(echo "head(iris,2)")
# Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa

From the tutorial:

from sqlalchemy import or_
filter(or_(User.name == 'ed', User.name == 'wendy'))

If you want to convert an Instant to a Date:

Date myDate = Date.from(instant);

And then you can use SimpleDateFormat for the formatting part of your question:

SimpleDateFormat formatter = new SimpleDateFormat("dd MM yyyy HH:mm:ss");
String formattedDate = formatter.format(myDate);

The @Devart's version is correct, but here are some improvements to avoid having error. I've edited the @Devart's answer, but it was not accepted.

SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @tables = NULL;
SELECT GROUP_CONCAT('`', table_name, '`') INTO @tables
  FROM information_schema.tables
  WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@tables,'dummy') INTO @tables;

SET @tables = CONCAT('DROP TABLE IF EXISTS ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;

This script will not raise error with NULL result in case when you already deleted all tables in the database by adding at least one nonexistent - "dummy" table.

And it fixed in case when you have many tables.

And This small change to drop all view exist in the Database

SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @views = NULL;
SELECT GROUP_CONCAT('`', TABLE_NAME, '`') INTO @views
  FROM information_schema.views
  WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@views,'dummy') INTO @views;

SET @views = CONCAT('DROP VIEW IF EXISTS ', @views);
PREPARE stmt FROM @views;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;

It assumes that you run the script from Database you want to delete. Or run this before:

USE REPLACE_WITH_DATABASE_NAME_YOU_WANT_TO_DELETE;

Thank you to Steve Horvath to discover the issue with backticks.

When using Python 2.4, try

inf = float("9e999")
nan = inf - inf

I am facing the issue when I was porting the simplejson to an embedded device which running the Python 2.4, float("9e999") fixed it. Don't use inf = 9e999, you need convert it from string. -inf gives the -Infinity.

This HTML is fine:

<a href="#" id="contactUs">Contact Us</a>                   
<div id="dialog" title="Contact form">
  <p>appear now</p>
</div>

You need to initialize the Dialog (not sure if you are doing this):

$(function() {
  // this initializes the dialog (and uses some common options that I do)
  $("#dialog").dialog({
    autoOpen : false, modal : true, show : "blind", hide : "blind"
  });

  // next add the onclick handler
  $("#contactUs").click(function() {
    $("#dialog").dialog("open");
    return false;
  });
});

I know that this question has been asked for a long time but as of today one simple answer is:

<img src="image.png" style="width: 55vw; min-width: 330px;" />

The use of vw in here tells that the width is relative to 55% of the width of the viewport.

All the major browsers nowadays support this.

Using Context,We can clear app specific files like preference,database file. I have used below code for UI testing using Espresso.

    @Rule
    public ActivityTestRule<HomeActivity> mActivityRule = new ActivityTestRule<>(
            HomeActivity.class);

    public static void clearAppInfo() {
        Activity mActivity = testRule.getActivity();
        SharedPreferences prefs =
                PreferenceManager.getDefaultSharedPreferences(mActivity);
        prefs.edit().clear().commit();
        mActivity.deleteDatabase("app_db_name.db");
    }

if you want to find it in MB do this

SELECT table_schema                                        "DB Name", 
   Round(Sum(data_length + index_length) / 1024 / 1024, 1) "DB Size in MB" 
FROM   information_schema.tables 
GROUP  BY table_schema; 

This approach works for me in SQLite and MySQL. It may work with others, please let me know your experience.

• Works if rows are present
• Works if no rows are present (test with DELETE FROM table)

Code:

$calendarDatabase = new \PDO('sqlite:calendar-of-tasks.db');    
$statement = $calendarDatabase->query('SELECT *, COUNT(*) FROM data LIMIT 1');
$columns = array_keys($statement->fetch(PDO::FETCH_ASSOC));
array_pop($columns);
var_dump($columns);

I make no guarantees that this is valid SQL per ANSI or other, but it works for me.

I have found answers to my confusions.

There is a very important difference between the root and the alias directives. This difference exists in the way the path specified in the root or the alias is processed.

In case of the root directive, full path is appended to the root including the location part, whereas in case of the alias directive, only the portion of the path NOT including the location part is appended to the alias.

To illustrate:

Let's say we have the config

location /static/ {
    root /var/www/app/static/;
    autoindex off;
}

In this case the final path that Nginx will derive will be

/var/www/app/static/static

This is going to return 404 since there is no static/ within static/

This is because the location part is appended to the path specified in the root. Hence, with root, the correct way is

location /static/ {
    root /var/www/app/;
    autoindex off;
}

On the other hand, with alias, the location part gets dropped. So for the config

location /static/ {
    alias /var/www/app/static/;
    autoindex off;           ?
}                            |
                             pay attention to this trailing slash

the final path will correctly be formed as

/var/www/app/static

The case of trailing slash for alias directive

There is no definitive guideline about whether a trailing slash is mandatory per Nginx documentation, but a common observation by people here and elsewhere seems to indicate that it is.

A few more places have discussed this, not conclusively though.

https://serverfault.com/questions/376162/how-can-i-create-a-location-in-nginx-that-works-with-and-without-a-trailing-slas

I had the same problem. The problem sit in the Excel Source task. When you setup this task the first time, the task will connect to the specified Excel file (via the Excel connection) and decide what type each column is based on the current spreadsheet.

Thus, if you set up the Excel Source task, just make sure that the columns that should be text only has text in the column. This means that the Excel Source task will always assume that any subsequent spreadsheets will have the same format and will read 12345 as text because the column was text when the task was set up.

Hope it makes sense!

Change your network adapter to a bridged connection, this will directly connect to your computers physical network.

In my case i did following thing. In the UserMaster userId is PK and in UserAccess userId is FK of UserMaster

UserAccess.belongsTo(UserMaster,{foreignKey: 'userId'});
UserMaster.hasMany(UserAccess,{foreignKey : 'userId'});
var userData = await UserMaster.findAll({include: [UserAccess]});

In case you're here looking for something to list the keys of an n-depth nested object as a flat array:

const getObjectKeys = (obj, prefix = '') => {_x000D_
  return Object.entries(obj).reduce((collector, [key, val]) => {_x000D_
    const newKeys = [ ...collector, prefix ? `${prefix}.${key}` : key ]_x000D_
    if (Object.prototype.toString.call(val) === '[object Object]') {_x000D_
      const newPrefix = prefix ? `${prefix}.${key}` : key_x000D_
      const otherKeys = getObjectKeys(val, newPrefix)_x000D_
      return [ ...newKeys, ...otherKeys ]_x000D_
    }_x000D_
    return newKeys_x000D_
  }, [])_x000D_
}_x000D_
_x000D_
console.log(getObjectKeys({a: 1, b: 2, c: { d: 3, e: { f: 4 }}}))

Just store the property name in a variable, and use the variable to access the property. Like this:

$name = 'Name';

$obj->$name = 'something';
$get = $obj->$name;

>>> import numpy as np
>>> a = np.array([[1,2,3],[4,3,1]])
>>> i,j = np.unravel_index(a.argmax(), a.shape)
>>> a[i,j]
4

If you want to use spring jdbctemplate and don't want to deal with connection staff, you can use following:

jdbcTemplate.query("select * from books", new RowCallbackHandler() {
        public void processRow(ResultSet resultSet) throws SQLException {
            ResultSetMetaData rsmd = resultSet.getMetaData();
            for (int i = 1; i <= rsmd.getColumnCount(); i++ ) {
                String name = rsmd.getColumnName(i);
                // Do stuff with name
            }
        }
    });

You can try something like this:

List<String> list = new ArrayList<String>(Arrays.asList(array));

public ArrayList(Collection c)

Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator. The ArrayList instance has an initial capacity of 110% the size of the specified collection.

Taken from here

/// <summary>
/// Contains global variables for project.

public static class GlobalVar
{
/// <summary>

public const string GlobalString = "Important Text";

/// <summary>
/// Static value protected by access routine.

static int _globalValue;

/// <summary>
/// Access routine for global variable.

public static int GlobalValue
{

{
    return _globalValue;
}
set
{
    _globalValue = value;
}
}

public static bool GlobalBoolean;
}

Upload buttons are a pain to style because it styles the input and not the button.

but you can use this trick:

http://www.quirksmode.org/dom/inputfile.html

Summary:

1. Take a normal <input type="file"> and put it in an element with position: relative.

2. To this same parent element, add a normal <input> and an image, which have the correct styles. Position these elements absolutely, so that they occupy the same place as the <input type="file">.

3. Set the z-index of the <input type="file"> to 2 so that it lies on top of the styled input/image.

4. Finally, set the opacity of the <input type="file"> to 0. The <input type="file"> now becomes effectively invisible, and the styles input/image shines through, but you can still click on the "Browse" button. If the button is positioned on top of the image, the user appears to click on the image and gets the normal file selection window. (Note that you can't use visibility: hidden, because a truly invisible element is unclickable, too, and we need the to remain clickable)

Go to Project-><Projectname> Properties. Then click on the Debug tab, and fill in your arguments in the textbox called Command line arguments.

i like to use a littly tiny library called class-transformer.

it can handle nested-objects, map strings to date-objects and handle different json-property-names a lot more.

Maybe worth a look.

import { Type, plainToClass, Expose } from "class-transformer";
import 'reflect-metadata';

export class Employee{
    @Expose({ name: "uid" })
    id: number;

    firstname: string;
    lastname: string;
    birthdate: Date;
    maxWorkHours: number;
    department: string;

    @Type(() => Permission)
    permissions: Permission[] = [];
    typeOfEmployee: string;
    note: string;

    @Type(() => Date)
    lastUpdate: Date;
}

export class Permission {
  type : string;
}

let json:string = {
    "uid": 123,
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",
    "lastname": "<anystring>",
    "birthdate": "<anydate>",
    "maxWorkHours": 1,
    "username": "<anystring>",
    "permissions": [
      {'type' : 'read'},

}

console.log(plainToClass(Employee, json));

Connecting to Oracle is ugly. Here is some cleaner code with a using statement. A lot of the other samples don't call the IDisposable Methods on the objects they create.

using (OracleConnection connection = new OracleConnection("ConnectionString"))
    using (OracleCommand command = new OracleCommand("ProcName", connection))             
    {
          command.CommandType = CommandType.StoredProcedure;
          command.Parameters.Add("ParameterName", OracleDbType.Varchar2).Value = "Your Data Here";
          command.Parameters.Add("SomeOutVar", OracleDbType.Varchar2, 120);
          command.Parameters["return_out"].Direction = ParameterDirection.Output;
          command.Parameters.Add("SomeOutVar1", OracleDbType.Varchar2, 120);
          command.Parameters["return_out2"].Direction = ParameterDirection.Output;
          connection.Open();
          command.ExecuteNonQuery();
          string SomeOutVar = command.Parameters["SomeOutVar"].Value.ToString();
          string SomeOutVar1 = command.Parameters["SomeOutVar1"].Value.ToString();

When entered as the reference of a Named range, it refers to range on the sheet the named range is used on.

For example, create a named range MyName refering to =SUM(!B1:!K1)

Place a formula on Sheet1 =MyName. This will sum Sheet1!B1:K1

Now place the same formula (=MyName) on Sheet2. That formula will sum Sheet2!B1:K1

Note: (as pnuts commented) this and the regular SheetName!B1:K1 format are relative, so reference different cells as the =MyName formula is entered into different cells.

Use

num = num.toFixed(2);

Where 2 is the number of decimal places

Edit:

Here's the function to format number as you want

function formatNumber(number)
{
    number = number.toFixed(2) + '';
    x = number.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
        x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    return x1 + x2;
}

Since someone mentioned efficiency, I've benchmarked the functions given so far out of curiosity:

function startsWith1($str, $char) {
    return strpos($str, $char) === 0;
}
function startsWith2($str, $char) {
    return stripos($str, $char) === 0;
}
function startsWith3($str, $char) {
    return substr($str, 0, 1) === $char;
}
function startsWith4($str, $char){
    return $str[0] === $char;
}
function startsWith5($str, $char){
    return (bool) preg_match('/^' . $char . '/', $str);
}
function startsWith6($str, $char) {
    if (is_null($encoding)) $encoding = mb_internal_encoding();
    return mb_substr($str, 0, mb_strlen($char, $encoding), $encoding) === $char;
}

Here are the results on my average DualCore machine with 100.000 runs each

As you can see, treating the haystack as array to find out the char at the first position is always the fastest solution. It is also always performing at equal speed, regardless of string length. Using strpos is faster than substr for short strings but slower for long strings, when the string does not start with the prefix. The difference is irrelevant though. stripos is incredibly slow with long strings. preg_match performs mostly the same regardless of string length, but is only mediocre in speed. The mb_substr solution performs worst, while probably being more reliable though.

Given that these numbers are for 100.000 runs, it should be obvious that we are talking about 0.0000x seconds per call. Picking one over the other for efficiency is a worthless micro-optimization, unless your app is doing startsWith checking for a living.

It's not what the OP asked for (capturing groups) but you can extract the numbers using:

S='This is a sample 123 text and some 987 numbers'
echo "$S" | sed 's/ /\n/g' | sed -r '/([0-9]+)/ !d'

Gives the following:

123
987

They've changed it in JUnit 5 (expected: InvalidArgumentException, actual: invoked method) and code looks like this one:

@Test
public void wrongInput() {
    Throwable exception = assertThrows(InvalidArgumentException.class,
            ()->{objectName.yourMethod("WRONG");} );
}

Made a simple implementation of what I believe to be what you want to achieve. You can use the class later with the following arguments:

• int (milliseconds to wait until to run the code)
• bool (if true it returns instantly and runs the code after specified time on another thread)
• variable arguments (exactly what you'd feed to std::bind)

You can change std::chrono::milliseconds to std::chrono::nanoseconds or microseconds for even higher precision and add a second int and a for loop to specify for how many times to run the code.

Here you go, enjoy:

#include <functional>
#include <chrono>
#include <future>
#include <cstdio>

class later
{
public:
    template <class callable, class... arguments>
    later(int after, bool async, callable&& f, arguments&&... args)
    {
        std::function<typename std::result_of<callable(arguments...)>::type()> task(std::bind(std::forward<callable>(f), std::forward<arguments>(args)...));

        if (async)
        {
            std::thread([after, task]() {
                std::this_thread::sleep_for(std::chrono::milliseconds(after));
                task();
            }).detach();
        }
        else
        {
            std::this_thread::sleep_for(std::chrono::milliseconds(after));
            task();
        }
    }

};

void test1(void)
{
    return;
}

void test2(int a)
{
    printf("%i\n", a);
    return;
}

int main()
{
    later later_test1(1000, false, &test1);
    later later_test2(1000, false, &test2, 101);

    return 0;
}

Outputs after two seconds:

101

Look at the following commands (especially the commented block).

DROP TABLE foo;
DROP TABLE bar;

CREATE TABLE foo (a int, b text);
CREATE TABLE bar (a serial, b text);

INSERT INTO foo (a, b) SELECT i, 'foo ' || i::text FROM generate_series(1, 5) i;
INSERT INTO bar (b) SELECT 'bar ' || i::text FROM generate_series(1, 5) i;

-- blocks of commands to turn foo into bar
CREATE SEQUENCE foo_a_seq;
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq');
ALTER TABLE foo ALTER COLUMN a SET NOT NULL;
ALTER SEQUENCE foo_a_seq OWNED BY foo.a;    -- 8.2 or later

SELECT MAX(a) FROM foo;
SELECT setval('foo_a_seq', 5);  -- replace 5 by SELECT MAX result

INSERT INTO foo (b) VALUES('teste');
INSERT INTO bar (b) VALUES('teste');

SELECT * FROM foo;
SELECT * FROM bar;
