The best way to get filetype-specific indentation is to use filetype plugin indent on in your vimrc. Then you can specify things like set sw=4 sts=4 et in .vim/ftplugin/c.vim, for example, without having to make those global for all files being edited and other non-C type syntaxes will get indented correctly, too (even lisps).

The accepted answer works, but you have to do a "Select All" first -- every time -- and I'm way too lazy for that.

And it turns out, it's not super trivial -- I figured I'd post this here in an attempt to save like-minded individuals the 30 minutes it takes to track all this down. -- Also note: this approach restores the original selection when it's done (and it happens so fast, you don't even notice the selection was ever changed).

1.) First, add a custom command to your init script (File->Open Your Init Script, then paste this at the bottom):

atom.commands.add 'atom-text-editor', 'custom:reformat', ->
    editor = atom.workspace.getActiveTextEditor();
    oldRanges = editor.getSelectedBufferRanges();
    editor.selectAll();
    atom.commands.dispatch(atom.views.getView(editor), 'editor:auto-indent')
    editor.setSelectedBufferRanges(oldRanges);

2.) Bind "custom:reformat" to a key (File->Open Your Keymap, then paste this at the bottom):

'atom-text-editor':
    'ctrl-alt-d': 'custom:reformat'

3.) Restart Atom (the init.coffee script only runs when atom is first launched).

You can use the command palette to solve this issue.

Step 1: Ctrl + Shift + P (to activate the command palette)

Step 2: Type "Indentation", Choose "Indentation: Convert to Tabs"

Reformat affects the whole source code and may rebreak your lines, while Correct Indentation only affects the whitespace at the beginning of the lines.

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

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

Here's a neat trick in Sublime Text 2 or 3 to convert your indentation spacing in a document.

TL;DR:

Converting from 2 spaces to 4 spaces:

Ensure tab width is set to 2. Convert your 2-space indentation to tabs, switch to tab width 4, and then convert the indentation back to spaces.

The detailed description:

Go to:

View -> Indentation

It should read:

• Indent using spaces [x]
• Tab width: 2

Select:

• Convert Indentation to Tabs

Then Select:

• Tab width: 4
• Convert Indentation to Spaces

Done.

Mac users can avoid auto formatting by reading directly from the pasteboard with:

:r !pbpaste

The Identator plugin works to me in Brackets Release 1.13 versión 1.13.0-17696 (release 49d29a8bc) on S.O. Windows 10

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.

For example, suppose the browser makes a request with the following headers:

Origin: http://yourdomain.com
Access-Control-Request-Method: POST
Access-Control-Request-Headers: X-Custom-Header

Your server should then respond with the following headers:

Access-Control-Allow-Origin: http://yourdomain.com
Access-Control-Allow-Methods: GET, POST
Access-Control-Allow-Headers: X-Custom-Header

Pay special attention to the Access-Control-Allow-Headers response header. The value of this header should be the same headers in the Access-Control-Request-Headers request header, and it can not be '*'.

Once you send this response to the preflight request, the browser will make the actual request. You can learn more about CORS here: http://www.html5rocks.com/en/tutorials/cors/

The SQL-Server implementation of this will be:

SELECT SALARY FROM EMPLOYEES OFFSET 2 ROWS FETCH NEXT 1 ROWS ONLY

Since I can't comment on Jasper's answer, I'd like to point out a small bug in his solution:

str.replace(/[^a-z0-9\s]/gi, '').replace(/[_\s]/g, '-');

The problem is that first code removes all the hyphens and then tries to replace them :) You should reverse the replace calls and also add hyphen to second replace regex. Like this:

str.replace(/[_\s]/g, '-').replace(/[^a-z0-9-\s]/gi, '');

Any Table ID

Use: INT(11).

MySQL indexes will be able to parse through an int list fastest.

Anything Security

Use: BINARY(x), or BLOB(x).

You can store security tokens, etc., as hex directly in BINARY(x) or BLOB(x). To retrieve from binary-type, use SELECT HEX(field)... or SELECT ... WHERE field = UNHEX("ABCD....").

Anything Date

Use: DATETIME, DATE, or TIME.

Always use DATETIME if you need to store both date and time (instead of a pair of fields), as a DATETIME indexing is more amenable to date-comparisons in MySQL.

Anything True-False

Use: BIT(1) (MySQL 8-only.) Otherwise, use BOOLEAN(1).

BOOLEAN is actually just an alias of TINYINT(1), which actually stores 0 to 255 (not exactly a true/false, is it?).

Anything You Want to call `SUM()`, `MAX()`, or similar functions on

Use: INT(11).

VARCHAR or other types of fields won't work with the SUM(), etc., functions.

Anything Over 1,000 Characters

Use: TEXT.

Max limit is 65,535.

Anything Over 65,535 Characters

Use: MEDIUMTEXT.

Max limit is 16,777,215.

Anything Over 16,777,215 Characters

Use: LONGTEXT.

Max limit is 4,294,967,295.

FirstName, LastName

Use : VARCHAR(255).

UTF-8 characters can take up three characters per visible character, and some cultures do not distinguish firstname and lastname. Additionally, cultures may have disagreements about which name is first and which name is last. You should name these fields Person.GivenName and Person.FamilyName.

Email Address

Use : VARCHAR(256).

The definition of an e-mail path is set in RFC821 in 1982. The maximum limit of an e-mail was set by RFC2821 in 2001, and these limits were kept unchanged by RFC5321 in 2008. (See the section: 4.5.3.1. Size Limits and Minimums.) RFC3696, published 2004, mistakenly cites the email address limit as 320 characters, but this was an "info-only" RFC that explicitly "defines no standards" according to its intro, so disregard it.

Phone

Use: VARCHAR(255).

You never know when the phone number will be in the form of "1800...", or "1-800", or "1-(800)", or if it will end with "ext. 42", or "ask for susan".

ZipCode

Use: VARCHAR(10).

You'll get data like 12345 or 12345-6789. Use validation to cleanse this input.

URL

Use: VARCHAR(2000).

Official standards support URL's much longer than this, but few modern browsers support URL's over 2,000 characters. See this SO answer: What is the maximum length of a URL in different browsers?

Price

Use: DECIMAL(11,2).

It goes up to 11.

Old answer:

First, in your AppDelegate .h file:

#import <AVFoundation/AVFoundation.h>

@interface AppDelegate : NSObject <UIApplicationDelegate> {

    AVCaptureSession *torchSession;

}

@property (nonatomic, retain) AVCaptureSession * torchSession;

@end

Then in your AppDelegate .m file:

@implementation AppDelegate

@synthesize torchSession;

- (void)dealloc {
    [torchSession release];

    [super dealloc];
}

- (id) init {
    if ((self = [super init])) {

    // initialize flashlight
    // test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
        Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
        if (captureDeviceClass != nil) {

            AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

            if ([device hasTorch] && [device hasFlash]){

                if (device.torchMode == AVCaptureTorchModeOff) {

                NSLog(@"Setting up flashlight for later use...");

                    AVCaptureDeviceInput *flashInput = [AVCaptureDeviceInput deviceInputWithDevice:device error: nil];
                    AVCaptureVideoDataOutput *output = [[AVCaptureVideoDataOutput alloc] init];

                    AVCaptureSession *session = [[AVCaptureSession alloc] init];

                [session beginConfiguration];
                    [device lockForConfiguration:nil];

                    [session addInput:flashInput];
                    [session addOutput:output];

                    [device unlockForConfiguration];

                    [output release];

                [session commitConfiguration];
                [session startRunning];

                [self setTorchSession:session];
                [session release];
                    }

            }

        }
    } 
    return self;
}

Then anytime you want to turn it on, just do something like this:

// test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {

    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

    [device lockForConfiguration:nil];

    [device setTorchMode:AVCaptureTorchModeOn];
    [device setFlashMode:AVCaptureFlashModeOn];

    [device unlockForConfiguration];

}

And similar for turning it off:

// test if this class even exists to ensure flashlight is turned on ONLY for iOS 4 and above
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {

    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

    [device lockForConfiguration:nil];

    [device setTorchMode:AVCaptureTorchModeOff];
    [device setFlashMode:AVCaptureFlashModeOff];

    [device unlockForConfiguration];
}

I have faced this error a lot of time, also research why this error occurs and finally, I caught this error, this error a silly error which occurs when we misspelled .xib file name.

NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"TableViewCell" owner:self options:nil];

At this point, I misspelled TableViewCell as TabelViewCell , because the perception of some time we read it as correct, this is the most common problem. Just copy your .xib file name, and paste it.

position: relative act as a parent element position: absolute act a child of relative position. you can see the below example

.postion-element{
   position:relative;
   width:200px;
   height:200px;
   background-color:green;
 }
.absolute-element{
  position:absolute;
  top:10px;
  left:10px;
  background-color:blue;
 }

This question is not specific to jQuery, but specific to JavaScript in general. The core problem is how to "channel" a variable in embedded functions. This is the example:

var abc = 1; // we want to use this variable in embedded functions

function xyz(){
  console.log(abc); // it is available here!
  function qwe(){
    console.log(abc); // it is available here too!
  }
  ...
};

This technique relies on using a closure. But it doesn't work with this because this is a pseudo variable that may change from scope to scope dynamically:

// we want to use "this" variable in embedded functions

function xyz(){
  // "this" is different here!
  console.log(this); // not what we wanted!
  function qwe(){
    // "this" is different here too!
    console.log(this); // not what we wanted!
  }
  ...
};

What can we do? Assign it to some variable and use it through the alias:

var abc = this; // we want to use this variable in embedded functions

function xyz(){
  // "this" is different here! --- but we don't care!
  console.log(abc); // now it is the right object!
  function qwe(){
    // "this" is different here too! --- but we don't care!
    console.log(abc); // it is the right object here too!
  }
  ...
};

this is not unique in this respect: arguments is the other pseudo variable that should be treated the same way — by aliasing.

It's not that key is a special word, but that dictionaries implement the iterator protocol. You could do this in your class, e.g. see this question for how to build class iterators.

In the case of dictionaries, it's implemented at the C level. The details are available in PEP 234. In particular, the section titled "Dictionary Iterators":

• Dictionaries implement a tp_iter slot that returns an efficient iterator that iterates over the keys of the dictionary. [...] This means that we can write

  for k in dict: ...
  

  which is equivalent to, but much faster than

  for k in dict.keys(): ...
  

  as long as the restriction on modifications to the dictionary (either by the loop or by another thread) are not violated.

• Add methods to dictionaries that return different kinds of iterators explicitly:

  for key in dict.iterkeys(): ...
  
  for value in dict.itervalues(): ...
  
  for key, value in dict.iteritems(): ...
  

  This means that for x in dict is shorthand for for x in dict.iterkeys().

In Python 3, dict.iterkeys(), dict.itervalues() and dict.iteritems() are no longer supported. Use dict.keys(), dict.values() and dict.items() instead.

First you need to declare your resources in dispatcher-servlet file like this :

<mvc:resources mapping="/resources/**" location="/resources/folder/" />

Any request with url mapping /resources/** will directly look for /resources/folder/.

Now in jsp file you need to include your css file like this :

<link href="<c:url value="/resources/css/main.css" />" rel="stylesheet">

Similarly you can include js files.

Hope this solves your problem.

I dont think there is any sdk support for sending mms in android. Look here Atleast I havent found yet. But a guy claimed to have it. Have a look at this post.

Send MMS from My application in android

Check if you did compress the driver or folder in where you put the .mdf file.

If so, plesae goto the driver or folder, change the compress option by

Properties -> Advanced and unticked the “Compress contents to save disk space” checkbox.

After above things, you should be able to start the service again.

(In the diagrams and text below, PC is the address of the branch instruction itself. PC+4 is the end of the branch instruction itself, and the start of the branch delay slot. Except in the absolute jump diagram.)

1. Branch Address Calculation

In MIPS branch instruction has only 16 bits offset to determine next instruction. We need a register added to this 16 bit value to determine next instruction and this register is actually implied by architecture. It is PC register since PC gets updated (PC+4) during the fetch cycle so that it holds the address of the next instruction.

We also limit the branch distance to -2^15 to +2^15 - 1 instruction from the (instruction after the) branch instruction. However, this is not real issue since most branches are local anyway.

So step by step :

• Sign extend the 16 bit offset value to preserve its value.
• Multiply resulting value with 4. The reason behind this is that If we are going to branch some address, and PC is already word aligned, then the immediate value has to be word-aligned as well. However, it makes no sense to make the immediate word-aligned because we would be wasting low two bits by forcing them to be 00.
• Now we have a 32 bit relative offset. Add this value to PC + 4 and that is your branch address.

2. Jump Address Calculation

For Jump instruction MIPS has only 26 bits to determine Jump location. Jumps are relative to PC in MIPS. Like branch, immediate jump value needs to be word-aligned; therefore, we need to multiply 26 bit address with four.

Again step by step:

• Multiply 26 bit value with 4.
• Since we are jumping relative to PC+4 value, concatenate first four bits of PC+4 value to left of our jump address.
• Resulting address is the jump value.

In other words, replace the lower 28 bits of the PC + 4 with the lower 26 bits of the fetched instruction shifted left by 2 bits.

Jumps are region-relative to the branch-delay slot, not necessarily the branch itself. In the diagram above, PC has already advanced to the branch delay slot before the jump calculation. (In a classic-RISC 5 stage pipeline, the BD was fetched in the same cycle the jump is decoded, so that PC+4 next instruction address is already available for jumps as well as branches, and calculating relative to the jump's own address would have required extra work to save that address.)

fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/

If you don't want to use fgets, following method will work for you :-

int readline(FILE *f, char *buffer, size_t len)
{
   char c; 
   int i;

   memset(buffer, 0, len);

   for (i = 0; i < len; i++)
   {   
      int c = fgetc(f); 

      if (!feof(f)) 
      {   
         if (c == '\r')
            buffer[i] = 0;
         else if (c == '\n')
         {   
            buffer[i] = 0;

            return i+1;
         }   
         else
            buffer[i] = c; 
      }   
      else
      {   
         //fprintf(stderr, "read_line(): recv returned %d\n", c);
         return -1; 
      }   
   }   

   return -1; 
}

I am giving one exapmle to undersand when do we use @Queryparam and @pathparam

For example I am taking one resouce is carResource class

If you want to make the inputs of your resouce method manadatory then use the param type as @pathaparam, if the inputs of your resource method should be optional then keep that param type as @QueryParam param

@Path("/car")
class CarResource
{
    @Get
    @produces("text/plain")
    @Path("/search/{carmodel}")
    public String getCarSearch(@PathParam("carmodel")String model,@QueryParam("carcolor")String color) {
        //logic for getting cars based on carmodel and color
            -----
        return cars
    }
}

For this resouce pass the request

req uri ://address:2020/carWeb/car/search/swift?carcolor=red

If you give req like this the resouce will gives the based car model and color

 req uri://address:2020/carWeb/car/search/swift

If you give req like this the resoce method will display only swift model based car

req://address:2020/carWeb/car/search?carcolor=red

If you give like this we will get ResourceNotFound exception because in the car resouce class I declared carmodel as @pathPram that is you must and should give the carmodel as reQ uri otherwise it will not pass the req to resouce but if you don't pass the color also it will pass the req to resource why because the color is @quetyParam it is optional in req.

you might have bash but it is still a windows window manager. Highlite some text in the bash terminal window. Right click on the title bar, select "Edit", select "Copy", Now Right Click again on the Title bar, select "Edit" , Select "Paste", Done. You should be able to Highlite text, hit "Enter" then Control V but this seems to be broken

<select name="aa" onchange="report(this.value)"> 
  <option value="">Please select</option>
  <option value="daily">daily</option>
  <option value="monthly">monthly</option>
</select>

using

function report(period) {
  if (period=="") return; // please select - possibly you want something else here

  const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
  loadXMLDoc(report,'responseTag');
  document.getElementById('responseTag').style.visibility='visible';
  document.getElementById('list_report').style.visibility='hidden';
  document.getElementById('formTag').style.visibility='hidden'; 
} 

Unobtrusive version:

<select id="aa" name="aa"> 
  <option value="">Please select</option>
  <option value="daily">daily</option>
  <option value="monthly">monthly</option>
</select>

using

window.addEventListener("load",function() {
  document.getElementById("aa").addEventListener("change",function() {
    const period = this.value;
    if (period=="") return; // please select - possibly you want something else here

    const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
    loadXMLDoc(report,'responseTag');
    document.getElementById('responseTag').style.visibility='visible';
    document.getElementById('list_report').style.visibility='hidden';
    document.getElementById('formTag').style.visibility='hidden'; 
  }); 
});

jQuery version - same select with ID

$(function() {
  $("#aa").on("change",function() {
    const period = this.value;
    if (period=="") return; // please select - possibly you want something else here

    var report = "script/"+((period == "daily")?"d":"m")+"_report.php";
    loadXMLDoc(report,'responseTag');
    $('#responseTag').show();
    $('#list_report').hide();
    $('#formTag').hide(); 
  }); 
});

True is equal to 1.

The information is not available through document.cookie, but if you're really desperate for it, you could try performing a request through the XmlHttpRequest object to the current page and access the cookie header using getResponseHeader().

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

Try this, this works for my code name is a String:

cursor = rdb.query(true, TABLE_PROFILE, new String[] { ID,
    REMOTEID, FIRSTNAME, LASTNAME, EMAIL, GENDER, AGE, DOB,
    ROLEID, NATIONALID, URL, IMAGEURL },                    
    LASTNAME + " like ?", new String[]{ name+"%" }, null, null, null, null);

Just to add my two cents' worth :-) I recently learned a way of handling anonymous objects. It can only be used when targeting the .NET 4 framework and that only when adding a reference to System.Web.dll but then it's quite simple:

...
using System.Web.Routing;
...

class Program
{
    static void Main(string[] args)
    {

        object anonymous = CallMethodThatReturnsObjectOfAnonymousType();
        //WHAT DO I DO WITH THIS?
        //I know! I'll use a RouteValueDictionary from System.Web.dll
        RouteValueDictionary rvd = new RouteValueDictionary(anonymous);
        Console.WriteLine("Hello, my name is {0} and I am a {1}", rvd["Name"], rvd["Occupation"]);
    }

    private static object CallMethodThatReturnsObjectOfAnonymousType()
    {
        return new { Id = 1, Name = "Peter Perhac", Occupation = "Software Developer" };
    }
}

In order to be able to add a reference to System.Web.dll you'll have to follow rushonerok's advice : Make sure your [project's] target framework is ".NET Framework 4" not ".NET Framework 4 Client Profile".

Add the following dependency to your pom.xml

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.5.2</version>
</dependency>

To retrieve it:

cat /proc/sys/kernel/threads-max

To set it:

echo 123456789 | sudo tee -a /proc/sys/kernel/threads-max

123456789 = # of threads

You could use a navigation property if its available. It produces an inner join in the SQL.

from s in db.Services
where s.ServiceAssignment.LocationId == 1
select s

I'm using SourceTree along with TortoiseMerge/Diff, which is very easy and convinient diff/merge tool.

If you'd like to use it as well, then:

1. Get standalone version of TortoiseMerge/Diff (quite old, since it doesn't ship standalone since version 1.6.7 of TortosieSVN, that is since July 2011). Links and details in this answer.

2. Unzip TortoiseIDiff.exe and TortoiseMerge.exe to any folder (c:\Program Files (x86)\Atlassian\SourceTree\extras\ in my case).

3. In SourceTree open Tools > Options > Diff > External Diff / Merge. Select TortoiseMerge in both dropdown lists.

4. Hit OK and point SourceTree to your location of TortoiseIDiff.exe and TortoiseMerge.exe.

After that, you can select Resolve Conflicts > Launch External Merge Tool from context menu on each conflicted file in your local repository. This will open up TortoiseMerge, where you can easily deal with all the conflicts, you have. Once finished, simply close TortoiseMerge (you don't even need to save changes, this will probably be done automatically) and after few seconds SourceTree should handle that gracefully.

The only problem is, that it automatically creates backup copy, even though proper option is unchecked.

I know it's a several years old post and you may solve your problem with above solution. However, i just want to suggest using InverseProperty for someone who still need. At least you don't need to change anything in OnModelCreating.

The below code is un-tested.

public class Team
{
    [Key]
    public int TeamId { get; set;} 
    public string Name { get; set; }

    [InverseProperty("HomeTeam")]
    public virtual ICollection<Match> HomeMatches { get; set; }

    [InverseProperty("GuestTeam")]
    public virtual ICollection<Match> GuestMatches { get; set; }
}


public class Match
{
    [Key]
    public int MatchId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}

You can read more about InverseProperty on MSDN: https://msdn.microsoft.com/en-us/data/jj591583?f=255&MSPPError=-2147217396#Relationships

Specifically, if you are dealing with a UserForm, then you might try the Repaint method. You might encounter an issue with DoEvents if you are using event triggers in your form. For instance, any keys pressed while a function is running will be sent by DoEvents The keyboard input will be processed before the screen is updated, so if you are changing cells on a spreadsheet by holding down one of the arrow keys on the keyboard, then the cell change event will keep firing before the main function finishes.

A UserForm will not be refreshed in some cases, because DoEvents will fire the events; however, Repaint will update the UserForm and the user will see the changes on the screen even when another event immediately follows the previous event.

In the UserForm code it is as simple as:

Me.Repaint

I have tried this snippet (in Xcode 8 Beta 6), and it is working fine.

let date1 = Date()
let date2 = Date().addingTimeInterval(100)

if date1 == date2 { ... }
else if date1 > date2 { ... }
else if date1 < date2 { ... }

Since the methods used in other answers seems quite complicated for such easy task, here is a new answer:

Instead of a ListedColormap, which produces a discrete colormap, you may use a LinearSegmentedColormap. This can easily be created from a list using the from_list method.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors

x,y,c = zip(*np.random.rand(30,3)*4-2)

norm=plt.Normalize(-2,2)
cmap = matplotlib.colors.LinearSegmentedColormap.from_list("", ["red","violet","blue"])

plt.scatter(x,y,c=c, cmap=cmap, norm=norm)
plt.colorbar()
plt.show()

More generally, if you have a list of values (e.g. [-2., -1, 2]) and corresponding colors, (e.g. ["red","violet","blue"]), such that the nth value should correspond to the nth color, you can normalize the values and supply them as tuples to the from_list method.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors

x,y,c = zip(*np.random.rand(30,3)*4-2)

cvals  = [-2., -1, 2]
colors = ["red","violet","blue"]

norm=plt.Normalize(min(cvals),max(cvals))
tuples = list(zip(map(norm,cvals), colors))
cmap = matplotlib.colors.LinearSegmentedColormap.from_list("", tuples)

plt.scatter(x,y,c=c, cmap=cmap, norm=norm)
plt.colorbar()
plt.show()

C++ supplies a string class that can be used like this:

#include <string>
#include <iostream>

int main() {
    std::string Something = "Some text";
    std::cout << Something << std::endl;
}

Certain versions of android do not fire proper tasks for updating the state of file system. You could trigger an explicit intent for updating the status of the file system. (I just tested after being in the same OP's situation)

adb shell am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///

(You could pass a specific filepath instead of file:/// like file:///sdcard )

As I understand your question..

From Java List class you have to methods add(E e) and get(int position).

add(E e)

Appends the specified element to the end of this list (optional operation).

get(int index)

Returns the element at the specified position in this list.

Example:

List<String> myString = new ArrayList<String>();

// How you add your data in string list
myString.add("Test 1");
myString.add("Test 2");
myString.add("Test 3");
myString.add("Test 4");

// retrieving data from string list array in for loop
for (int i=0;i < myString.size();i++)
{
  Log.i("Value of element "+i,myString.get(i));
}

But efficient way to iterate thru loop

for (String value : myString)
{
  Log.i("Value of element ",value);
}

Short and simple differences between Tcp and Udp protocol:

1) Tcp - Transmission control protocol and Udp - User datagram protocol.

2) Tcp is reliable protocol, Where as Udp is a unreliable protocol.

3) Tcp is a stream oriented, where as Udp is a message oriented protocol.

4) Tcp is a slower than Udp.

Use the glob function in a foreach loop to do whatever is an option. I also used the file_exists function in the example below to check if the directory exists before going any further.

$directory = 'my_directory/';
$extension = '.txt';

if ( file_exists($directory) ) {
   foreach ( glob($directory . '*' . $extension) as $file ) {
      echo $file;
   }
}
else {
   echo 'directory ' . $directory . ' doesn\'t exist!';
}

I know this answer is a bit late.
My purpose for this answer is for everyone's reference should they encounter this type of challenge with SQLite now or in the future and they're having a hard time with it.

Now, looking back at your query, it should be something like this.

CREATE TABLE people (id integer primary key autoincrement, first_name varchar(20), last_name varchar(20));

It works on my end. Like so,

Just in case you are working with SQLite, I suggest for you to check out DB Browser for SQLite. Works on different platforms as well.

The most important difference is this:

• In case of persist method, if the entity that is to be managed in the persistence context, already exists in persistence context, the new one is ignored. (NOTHING happened)

• But in case of merge method, the entity that is already managed in persistence context will be replaced by the new entity (updated) and a copy of this updated entity will return back. (from now on any changes should be made on this returned entity if you want to reflect your changes in persistence context)

It depends.

Start with Basic I/O, take a look at Properties, take a look at Preferences API and maybe even Java API for XML Processing and Java Architecture for XML Binding

And if none of those meet your particular needs, you could even look at using some kind of Database

I thought Activity was deprecated

No.

So for API Level 22 (with a minimum support for API Level 15 or 16), what exactly should I use both to host the components, and for the components themselves? Are there uses for all of these, or should I be using one or two almost exclusively?

Activity is the baseline. Every activity inherits from Activity, directly or indirectly.

FragmentActivity is for use with the backport of fragments found in the support-v4 and support-v13 libraries. The native implementation of fragments was added in API Level 11, which is lower than your proposed minSdkVersion values. The only reason why you would need to consider FragmentActivity specifically is if you want to use nested fragments (a fragment holding another fragment), as that was not supported in native fragments until API Level 17.

AppCompatActivity is from the appcompat-v7 library. Principally, this offers a backport of the action bar. Since the native action bar was added in API Level 11, you do not need AppCompatActivity for that. However, current versions of appcompat-v7 also add a limited backport of the Material Design aesthetic, in terms of the action bar and various widgets. There are pros and cons of using appcompat-v7, well beyond the scope of this specific Stack Overflow answer.

ActionBarActivity is the old name of the base activity from appcompat-v7. For various reasons, they wanted to change the name. Unless some third-party library you are using insists upon an ActionBarActivity, you should prefer AppCompatActivity over ActionBarActivity.

So, given your minSdkVersion in the 15-16 range:

• If you want the backported Material Design look, use AppCompatActivity

• If not, but you want nested fragments, use FragmentActivity

• If not, use Activity

Just adding from comment as note: AppCompatActivity extends FragmentActivity, so anyone who needs to use features of FragmentActivity can use AppCompatActivity.

I was trying to replace a really large string and for some reason regular expressions were throwing some errors/exceptions.

So I found this alternative to regular expressions which also runs pretty fast. At least it was fast enough for me:

var search = "search string";
var replacement = "replacement string";

document.body.innerHTML = document.body.innerHTML.split(search).join(replacement)

src: How to replace all occurrences of a string in JavaScript?

These are different implementations of the same interface. Each implementation has some advantages and some disadvantages (fast insert, slow search) or vice versa.

For details look at the javadoc of TreeMap, HashMap, LinkedHashMap.

declare your date column as NOT NULL, but without a default. Then add this trigger:

USE `ddb`;
DELIMITER $$
CREATE TRIGGER `default_date` BEFORE INSERT ON `dtable` FOR EACH ROW
if ( isnull(new.query_date) ) then
 set new.query_date=curdate();
end if;
$$
delimiter ;

You declare a delegate for the parameters:

public enum MyEvents { Event1 }

public delegate void MyEventHandler(MyEvents e);

public static event MyEventHandler EventTriggered;

Although all events in the framework takes a parameter that is or derives from EventArgs, you can use any parameters you like. However, people are likely to expect the pattern used in the framework, which might make your code harder to follow.

You could query the table_privileges table in the information schema:

SELECT table_catalog, table_schema, table_name, privilege_type
FROM   information_schema.table_privileges 
WHERE  grantee = 'MY_USER'

The second method, Task.Run, has been introduced in a later version of the .NET framework (in .NET 4.5).

However, the first method, Task.Factory.StartNew, gives you the opportunity to define a lot of useful things about the thread you want to create, while Task.Run doesn't provide this.

For instance, lets say that you want to create a long running task thread. If a thread of the thread pool is going to be used for this task, then this could be considered an abuse of the thread pool.

One thing you could do in order to avoid this would be to run the task in a separate thread. A newly created thread that would be dedicated to this task and would be destroyed once your task would have been completed. You cannot achieve this with the Task.Run, while you can do so with the Task.Factory.StartNew, like below:

Task.Factory.StartNew(..., TaskCreationOptions.LongRunning);

As it is stated here:

So, in the .NET Framework 4.5 Developer Preview, we’ve introduced the new Task.Run method. This in no way obsoletes Task.Factory.StartNew, but rather should simply be thought of as a quick way to use Task.Factory.StartNew without needing to specify a bunch of parameters. It’s a shortcut. In fact, Task.Run is actually implemented in terms of the same logic used for Task.Factory.StartNew, just passing in some default parameters. When you pass an Action to Task.Run:

Task.Run(someAction);

that’s exactly equivalent to:

Task.Factory.StartNew(someAction, 
    CancellationToken.None, TaskCreationOptions.DenyChildAttach, TaskScheduler.Default);

#include <stdio.h>
int n = 2;
int main()
{
     switch(n)
     {
          case 0: goto _4;break;
          case 1: goto _4;break;
          case 2: goto _4;break;
          case 3: goto _4;break;
          case 4:
              _4:
                printf("Funny and easy!\n");
                break;
          default:
                printf("Search on StackOverflow!\n");
                break;
     }
}

If you transferred these files through disk or other means, it is likely they were not saved properly.

I agree with @haha on this one, for the most part. But there are several cross-browser related issues with using the "float:right" and could ultimately give you more of a headache than you want. If you know what the widths are going to be for each column use a float:left on both and save yourself the trouble. Another thing you can incorporate into your methodology is build column classes into your CSS.

So try something like this:

CSS

.col-wrapper{width:960px; margin:0 auto;}
.col{margin:0 10px; float:left; display:inline;}
.col-670{width:670px;}
.col-250{width:250px;}

HTML

<div class="col-wrapper">
    <div class="col col-670">[Page Content]</div>
    <div class="col col-250">[Page Sidebar]</div>
</div>

What ever data you have inserted into one text file or log file that can put on one path in hdfs and then write a query as follows in hive

  hive>load data inpath<<specify inputpath>> into table <<tablename>>;

EXAMPLE:

hive>create table foo (id int, name string)
row format delimited
fields terminated by '\t' or '|'or ','
stored as text file;
table created..
    DATA INSERTION::
    hive>load data inpath '/home/hive/foodata.log' into table foo;

Try this you will get a string from the format method.

DecimalFormat df = new DecimalFormat("##0");

df.format((Math.round(doubleValue * 100.0) / 100.0));

I recommend PyInstaller, a simple python script can be converted to an exe with the following commands:

utils/Makespec.py [--onefile] oldlogs.py

which creates a yourprogram.spec file which is a configuration for building the final exe. Next command builds the exe from the configuration file:

utils/Build.py oldlogs.spec

In addition to the accepted answer I would like to give an answer that shows how to iterate directly over the Newtonsoft collections. It uses less code and I'm guessing its more efficient as it doesn't involve converting the collections.

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
//Parse the data
JObject my_obj = JsonConvert.DeserializeObject<JObject>(your_json);

foreach (KeyValuePair<string, JToken> sub_obj in (JObject)my_obj["ADDRESS_MAP"])
{
    Console.WriteLine(sub_obj.Key);
}

I started doing this myself because JsonConvert automatically deserializes nested objects as JToken (which are JObject, JValue, or JArray underneath I think).

I think the parsing works according to the following principles:

• Every object is abstracted as a JToken

• Cast to JObject where you expect a Dictionary

• Cast to JValue if the JToken represents a terminal node and is a value

• Cast to JArray if its an array

• JValue.Value gives you the .NET type you need

Quoting from the gcc website:

C++11 features are available as part of the "mainline" GCC compiler in the trunk of GCC's Subversion repository and in GCC 4.3 and later. To enable C++0x support, add the command-line parameter -std=c++0x to your g++ command line. Or, to enable GNU extensions in addition to C++0x extensions, add -std=gnu++0x to your g++ command line. GCC 4.7 and later support -std=c++11 and -std=gnu++11 as well.

So probably you use a version of g++ which doesn't support -std=c++11. Try -std=c++0x instead.

Availability of C++11 features is for versions >= 4.3 only.

$("input[type=checkbox]").on("change", function() { 

    if (this.checked) {

     }
});

Now i know ,the element is one of node

All node types in here"http://www.w3schools.com/dom/dom_nodetype.asp"

Element is between the start tag and end in the end tag

So text node is a node , but not a element.

for(int key: hm.keySet()) {
    if(hm.get(key).equals(value)) {
        System.out.println(key); 
    }
}

  public void ReadXmlFile()
    {
        string path = HttpContext.Current.Server.MapPath("~/App_Data"); // Finds the location of App_Data on server.
        XmlTextReader reader = new XmlTextReader(System.IO.Path.Combine(path, "XMLFile7.xml")); //Combines the location of App_Data and the file name
        while (reader.Read())
        {
            switch (reader.NodeType)
            {
                case XmlNodeType.Element:
                    break;
                case XmlNodeType.Text:
                    columnNames.Add(reader.Value);
                    break;
                case XmlNodeType.EndElement:
                    break;
            }
        }
    }

You can avoid the first statement and just specify the path name in constructor of XmlTextReader.

To get an element by its ID, use this:

document.getElementById("p2")

Instead of:

document.getElementsByName("p2")

So the final product would be:

document.getElementsById("p2").style.visibility = "hidden";

You could use javax.servlet.Filter if there wasn't a requirement to log java method that been executed.

But with this requirement you have to access information stored in handlerMapping of DispatcherServlet. That said, you can override DispatcherServlet to accomplish logging of request/response pair.

Below is an example of idea that can be further enhanced and adopted to your needs.

public class LoggableDispatcherServlet extends DispatcherServlet {

    private final Log logger = LogFactory.getLog(getClass());

    @Override
    protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
        if (!(request instanceof ContentCachingRequestWrapper)) {
            request = new ContentCachingRequestWrapper(request);
        }
        if (!(response instanceof ContentCachingResponseWrapper)) {
            response = new ContentCachingResponseWrapper(response);
        }
        HandlerExecutionChain handler = getHandler(request);

        try {
            super.doDispatch(request, response);
        } finally {
            log(request, response, handler);
            updateResponse(response);
        }
    }

    private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, HandlerExecutionChain handler) {
        LogMessage log = new LogMessage();
        log.setHttpStatus(responseToCache.getStatus());
        log.setHttpMethod(requestToCache.getMethod());
        log.setPath(requestToCache.getRequestURI());
        log.setClientIp(requestToCache.getRemoteAddr());
        log.setJavaMethod(handler.toString());
        log.setResponse(getResponsePayload(responseToCache));
        logger.info(log);
    }

    private String getResponsePayload(HttpServletResponse response) {
        ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        if (wrapper != null) {

            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                int length = Math.min(buf.length, 5120);
                try {
                    return new String(buf, 0, length, wrapper.getCharacterEncoding());
                }
                catch (UnsupportedEncodingException ex) {
                    // NOOP
                }
            }
        }
        return "[unknown]";
    }

    private void updateResponse(HttpServletResponse response) throws IOException {
        ContentCachingResponseWrapper responseWrapper =
            WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        responseWrapper.copyBodyToResponse();
    }

}

HandlerExecutionChain - contains the information about request handler.

You then can register this dispatcher as following:

    @Bean
    public ServletRegistrationBean dispatcherRegistration() {
        return new ServletRegistrationBean(dispatcherServlet());
    }

    @Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
    public DispatcherServlet dispatcherServlet() {
        return new LoggableDispatcherServlet();
    }

And here's the sample of logs:

http http://localhost:8090/settings/test
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=500, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475814077,"status":500,"error":"Internal Server Error","exception":"java.lang.RuntimeException","message":"org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.RuntimeException","path":"/settings/test"}'}

http http://localhost:8090/settings/params
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=200, path='/settings/httpParams', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public x.y.z.DTO x.y.z.Controller.params()] and 3 interceptors', arguments=null, response='{}'}

http http://localhost:8090/123
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=404, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475840592,"status":404,"error":"Not Found","message":"Not Found","path":"/123"}'}

UPDATE

In case of errors Spring does automatic error handling. Therefore, BasicErrorController#error is shown as request handler. If you want to preserve original request handler, then you can override this behavior at spring-webmvc-4.2.5.RELEASE-sources.jar!/org/springframework/web/servlet/DispatcherServlet.java:971 before #processDispatchResult is called, to cache original handler.

For Windows

I had the same problem, I tried to reinstall and didn't worked for me.

Remove "C:\Program Files(x86)\nodejs" from your system enviorment PATH and thats it!

autoResetEvent.WaitOne()

is similar to

try
{
   manualResetEvent.WaitOne();
}
finally
{
   manualResetEvent.Reset();
}

as an atomic operation

update of @Vladimir Tolstikov's answer

Create a Child Component that use ngOnChanges.

ChildComponent.ts::

import { Component, OnChanges, Input } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'child',
  templateUrl: 'child.component.html',
})

export class ChildComponent implements OnChanges {
  @Input() child_id;

  constructor(private route: ActivatedRoute) { }

  ngOnChanges() {
    // create header using child_id
    console.log(this.child_id);
  }
}

now use it in MasterComponent's template and pass data to ChildComponent like:

<child [child_id]="child_id"></child>

There are four ways to show queries:

1. This will show the last query executed of user model:

   debug($this->User->lastQuery());  
   

2. This will show all executed query of user model:

   $log = $this->User->getDataSource()->getLog(false, false);       
   debug($log);
   

3. This will show a log of all queries:

   $db =& ConnectionManager::getDataSource('default');
   $db->showLog();
   

4. If you want to show all queries log all over the application you can use in view/element/filename.ctp.

   <?php echo $this->element('sql_dump'); ?>
   

Does it matter which is faster, if they don't do the same thing? Comparing the performance of statements with different meaning seems like a bad idea.

is tells you if the object implements ClassA anywhere in its type heirarchy. GetType() tells you about the most-derived type.

Not the same thing.

If your backgrounds are in the drawable folder right now try moving the images from drawable to drawable-nodpi folder in your project. This worked for me, seems that else the images are rescaled by them self..

Log returns are simply the natural log of 1 plus the arithmetic return. So how about this?

df['pct_change'] = df.price.pct_change()
df['log_return'] = np.log(1 + df.pct_change)

Even more concise, utilizing Ximix's suggestion:

df['log_return'] = np.log1p(df.price.pct_change())

getView() method create new View or ViewGroup for each row of Listview or Spinner . You can define this View or ViewGroup in a Layout XML file in res/layout folder and can give the reference it to Adapter class Object.

if you have 4 item in a Array passed to Adapter. getView() method will create 4 View for 4 rows of Adaper.

LayoutInflater class has a Method inflate() whic create View Object from XML resource layout.

MY UPDATE TO TONY L'S ANSWER This is the modded version of his answer that I use religiously now. I thought I would share it, as it adds slightly more functionality to it for various situations you may have, such as different types of position or only wanting horizontal/vertical centering rather than both.

center.js:

// We add a pos parameter so we can specify which position type we want

// Center it both horizontally and vertically (dead center)
jQuery.fn.center = function (pos) {
    this.css("position", pos);
    this.css("top", ($(window).height() / 2) - (this.outerHeight() / 2));
    this.css("left", ($(window).width() / 2) - (this.outerWidth() / 2));
    return this;
}

// Center it horizontally only
jQuery.fn.centerHor = function (pos) {
    this.css("position", pos);
    this.css("left", ($(window).width() / 2) - (this.outerWidth() / 2));
    return this;
}

// Center it vertically only
jQuery.fn.centerVer = function (pos) {
    this.css("position", pos);
    this.css("top", ($(window).height() / 2) - (this.outerHeight() / 2));
    return this;
}

In my <head>:

<script src="scripts/center.js"></script>

Examples of usage:

$("#example1").centerHor("absolute")
$("#example2").centerHor("fixed")

$("#example3").centerVer("absolute")
$("#example4").centerVer("fixed")

$("#example5").center("absolute")
$("#example6").center("fixed")

It works with any positioning type, and can be used throughout your entire site easily, as well as easily portable to any other site you create. No more annoying workarounds for centering something properly.

Hope this is useful for someone out there! Enjoy.

Prior to PHP 7, the session_start() function did not directly accept any configuration options. Now you can do it this way

<?php
// This sends a persistent cookie that lasts a day.
session_start([
    'cookie_lifetime' => 86400,
]);
?>

Reference: https://php.net/manual/en/function.session-start.php#example-5976

As suggested by Alan, function 'mapply' applies a function to multiple Multiple Lists or Vector Arguments:

mapply(myfun, arg1, arg2)

See man page: https://stat.ethz.ch/R-manual/R-devel/library/base/html/mapply.html

Give this a try:

This detects the scroll stop after 1 milisecond (or change it) using a global timer:

var scrollTimer;

$(window).on("scroll",function(){
    clearTimeout(scrollTimer);
    //Do  what you want whilst scrolling
    scrollTimer=setTimeout(function(){afterScroll()},1);
})

function afterScroll(){
    //I catched scroll stop.
}

You can use FFserver to stream a video using RTSP.

Just change console syntax to something like this:

ffmpeg -i space.mp4 -vcodec libx264 -tune zerolatency -crf 18 http://localhost:1234/feed1.ffm

Create a ffserver.config file (sample) where you declare HTTPPort, RTSPPort and SDP stream. Your config file could look like this (some important stuff might be missing):

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

SELECT count(*) AS count_1
FROM "table"

Usage from the SQL Expression layer

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

metadata = MetaData()

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

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

Usage from the ORM layer

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

from sqlalchemy.sql.expression import func

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

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

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

I have the same problem, and i realize that. When we create adapter and set it to listview, listview will point to object somewhere in memory which adapter hold, data in this object will show in listview.

adapter = new CustomAdapter(data);
listview.setadapter(adapter);

if we create an object for adapter with another data again and notifydatasetchanged():

adapter = new CustomAdapter(anotherdata);
adapter.notifyDataSetChanged();

this will do not affect to data in listview because the list is pointing to different object, this object does not know anything about new object in adapter, and notifyDataSetChanged() affect nothing. So we should change data in object and avoid to create a new object again for adapter

In my case we were setting the div id as a number and setting the href="#123", this did not work.. adding a prefix to the id helped.

Example: This did not work-

<li> <a data-toggle="tab" href="#@i"> <li/>
...
<div class="tab-pane" id="#@i">

This worked:

<li><a data-toggle="tab" href="#prefix@i"><li/>
...
<div class="tab-pane" id="#prefix@i">

A major cause of EXC_BAD_ACCESS is from trying to access released objects.

To find out how to troubleshoot this, read this document: DebuggingAutoReleasePool

Even if you don't think you are "releasing auto-released objects", this will apply to you.

This method works extremely well. I use it all the time with great success!!

In summary, this explains how to use Cocoa's NSZombie debugging class and the command line "malloc_history" tool to find exactly what released object has been accessed in your code.

Sidenote:

Running Instruments and checking for leaks will not help troubleshoot EXC_BAD_ACCESS. I'm pretty sure memory leaks have nothing to do with EXC_BAD_ACCESS. The definition of a leak is an object that you no longer have access to, and you therefore cannot call it.

UPDATE: I now use Instruments to debug Leaks. From Xcode 4.2, choose Product->Profile and when Instruments launches, choose "Zombies".

[[NSBundle mainBundle] pathForResource:@"marqueeMusic" ofType:@"html"];

It may be late but if the file from pathForResource is nil you should add it in the Build Phases > Copy Bundle Resources.

Am I missing something? You can just convert offer_date in the comparison:

SELECT *
FROM offers
WHERE to_char(offer_date, 'YYYYMM') = (SELECT to_date(create_date, 'YYYYMM') FROM customers where id = '12345678') AND
      offer_rate > 0 

If you want to export HTML to PDF. You have many options. without node even

Option 1: Have a button on your html page that calls window.print() function. use the browsers native html to pdf. use media queries to make your html page look good on a pdf. and you also have the print before and after events that you can use to make changes to your page before print.

Option 2. htmltocanvas or rasterizeHTML. convert your html to canvas , then call toDataURL() on the canvas object to get the image . and use a JavaScript library like jsPDF to add that image to a PDF file. Disadvantage of this approach is that the pdf doesnt become editable. If you want data extracted from PDF, there is different ways for that.

Option 3. @Jozzhard answer

use the --expression option

grep searchterm myfile.csv | sed --expression='s/replaceme/withthis/g'

First you have to include the file you call:

#!/bin/bash
. includes/included_file.sh

then you call your function like this:

#!/bin/bash
my_called_function

This is the syntax: "python.exe path""python script path"pause

"C:\Users\hp\AppData\Local\Programs\Python\Python37\python.exe" "D:\TS_V1\TS_V2.py"
pause

Basically what will be happening the screen will appear for seconds and then go off take care of these 2 things:

1. While saving the file you give extension as bat file but save it as a txt file and not all files and Encoding ANSI
2. If the program still doesn't run save the batch file and the python script in same folder and specify the path of this folder in Environment Variables.

You can override Django save method official doc about it.

The modified version of your code:

class Order(models.Model):
    cart = models.ForeignKey(Cart)
    add_date = models.DateTimeField(auto_now_add=True)
    order_number = models.IntegerField(default=0)  # changed here
    enable = models.BooleanField(default=True)

    def save(self, *args, **kwargs):
        self.order_number = self.order_number + 1
        super().save(*args, **kwargs)  # Call the "real" save() method.

Another way is to use signals. More one:

1. official Django docs about pre-save
2. stackoverflow example about using pre-save signal

SHOW FULL PROCESSLIST

If you don't use FULL, "only the first 100 characters of each statement are shown in the Info field".

When using phpMyAdmin, you should also click on the "Full texts" option ("? T ?" on top left corner of a results table) to see untruncated results.

find() and closest() seems slightly slower than:

$(this).parent().attr("id");

What worked for me is

svn revert --depth infinity deletedDir

You're thinking of Boolean algebra.

array_key_exists() is SLOW compared to isset(). A combination of these two (see below code) would help.

It takes the performance advantage of isset() while maintaining the correct checking result (i.e. return TRUE even when the array element is NULL)

if (isset($a['element']) || array_key_exists('element', $a)) {
       //the element exists in the array. write your code here.
}

The benchmarking comparison: (extracted from below blog posts).

array_key_exists() only : 205 ms
isset() only : 35ms
isset() || array_key_exists() : 48ms

See http://thinkofdev.com/php-fast-way-to-determine-a-key-elements-existance-in-an-array/ and http://thinkofdev.com/php-isset-and-multi-dimentional-array/

for detailed discussion.

As of Pandas 0.17 there is now a styling system which essentially provides formatted views of a DataFrame using Python format strings:

import pandas as pd
import numpy as np

constants = pd.DataFrame([('pi',np.pi),('e',np.e)],
                   columns=['name','value'])
C = constants.style.format({'name': '~~ {} ~~', 'value':'--> {:15.10f} <--'})
C

which displays

This is a view object; the DataFrame itself does not change formatting, but updates in the DataFrame are reflected in the view:

constants.name = ['pie','eek']
C

However it appears to have some limitations:

• Adding new rows and/or columns in-place seems to cause inconsistency in the styled view (doesn't add row/column labels):

  constants.loc[2] = dict(name='bogus', value=123.456)
  constants['comment'] = ['fee','fie','fo']
  constants
  

which looks ok but:

C

• Formatting works only for values, not index entries:

  constants = pd.DataFrame([('pi',np.pi),('e',np.e)],
                 columns=['name','value'])
  constants.set_index('name',inplace=True)
  C = constants.style.format({'name': '~~ {} ~~', 'value':'--> {:15.10f} <--'})
  C
  

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

Share and enjoy.

I came across this question when I was trying to find multiple filenames that I could not combine into a regular expression as described in @Chris J's answer, here is what worked for me

find . -name one.pdf -o -name two.txt -o -name anotherone.jpg

-o or -or is logical OR. See Finding Files on Gnu.org for more information.

I was running this on CygWin.

Another non-angular answer (I was facing the same issue building a react app on AWS Amplify).

As mentioned by Emmanuel it seems that it comes from the difference in the way memory is handled by node v10 vs node v12.

I tried to increase memory with no avail. But using node v12 did it.

Check how you can add nvm use $VERSION_NODE_12 to your build settings as explained by richard

frontend:
  phases:
    preBuild:
      commands:
        - nvm use $VERSION_NODE_12
        - npm ci
    build:
      commands:
        - nvm use $VERSION_NODE_12
        - node -v
        - npm run-script build

You can check the file

/usr/local/bin/mysql.server and see from where my.conf is being read from.

Usually it is from /etc/my.cnf or ~/my.cnf or ~/.my.cnf

Often, a Python program is run by naming a .py file on the command line:

$ python my_program.py

You can also create a directory or zipfile full of code, and include a __main__.py. Then you can simply name the directory or zipfile on the command line, and it executes the __main__.py automatically:

$ python my_program_dir
$ python my_program.zip
# Or, if the program is accessible as a module
$ python -m my_program

You'll have to decide for yourself whether your application could benefit from being executed like this.

Note that a __main__ module usually doesn't come from a __main__.py file. It can, but it usually doesn't. When you run a script like python my_program.py, the script will run as the __main__ module instead of the my_program module. This also happens for modules run as python -m my_module, or in several other ways.

If you saw the name __main__ in an error message, that doesn't necessarily mean you should be looking for a __main__.py file.

FYI : How to download data in CSV from Kibana:

In Kibana--> 1. Go to 'Discover' in left side

2. Select Index Field (based on your dashboard data) (*** In case if you are not sure which index to select-->go to management tab-->Saved Objects-->Dashboard-->select dashboard name-->scroll down to JSON-->you will see the Index name )

3. left side you see all the variables available in the data-->click over the variable name that you want to have in csv-->click add-->this variable will be added on the right side of the columns avaliable

4. Top right section of the kibana-->there is the time filter-->click -->select the duration for which you want the csv

5. Top upper right -->Reporting-->save this time/variable selection with a new report-->click generate CSV

6. Go to 'Management' in left side--> 'Reporting'-->download your csv

If you don't want to use DI or Factories. You can refactor your class in a little tricky way:

public class Foo {
    private Bar bar;

    public void foo(Bar bar){
        this.bar = (bar != null) ? bar : new Bar();
        bar.someMethod();
        this.bar = null;  // for simulating local scope
    }
}

And your test class:

@RunWith(MockitoJUnitRunner.class)
public class FooTest {
    @Mock Bar barMock;
    Foo foo;

    @Test
    public void testFoo() {
       foo = new Foo();
       foo.foo(barMock);
       verify(barMock, times(1)).someMethod();
    }
}

Then the class that is calling your foo method will do it like this:

public class thirdClass {

   public void someOtherMethod() {
      Foo myFoo = new Foo();
      myFoo.foo(null);
   }
}

As you can see when calling the method this way, you don't need to import the Bar class in any other class that is calling your foo method which is maybe something you want.

Of course the downside is that you are allowing the caller to set the Bar Object.

Hope it helps.

Try following command sequence on Ubuntu terminal:

sudo apt-get install software-properties-common

<url-pattern>/*</url-pattern>

The /* on a servlet overrides all other servlets, including all servlets provided by the servletcontainer such as the default servlet and the JSP servlet. Whatever request you fire, it will end up in that servlet. This is thus a bad URL pattern for servlets. Usually, you'd like to use /* on a Filter only. It is able to let the request continue to any of the servlets listening on a more specific URL pattern by calling FilterChain#doFilter().

<url-pattern>/</url-pattern>

The / doesn't override any other servlet. It only replaces the servletcontainer's builtin default servlet for all requests which doesn't match any other registered servlet. This is normally only invoked on static resources (CSS/JS/image/etc) and directory listings. The servletcontainer's builtin default servlet is also capable of dealing with HTTP cache requests, media (audio/video) streaming and file download resumes. Usually, you don't want to override the default servlet as you would otherwise have to take care of all its tasks, which is not exactly trivial (JSF utility library OmniFaces has an open source example). This is thus also a bad URL pattern for servlets. As to why JSP pages doesn't hit this servlet, it's because the servletcontainer's builtin JSP servlet will be invoked, which is already by default mapped on the more specific URL pattern *.jsp.

<url-pattern></url-pattern>

Then there's also the empty string URL pattern . This will be invoked when the context root is requested. This is different from the <welcome-file> approach that it isn't invoked when any subfolder is requested. This is most likely the URL pattern you're actually looking for in case you want a "home page servlet". I only have to admit that I'd intuitively expect the empty string URL pattern and the slash URL pattern / be defined exactly the other way round, so I can understand that a lot of starters got confused on this. But it is what it is.

Front Controller

In case you actually intend to have a front controller servlet, then you'd best map it on a more specific URL pattern like *.html, *.do, /pages/*, /app/*, etc. You can hide away the front controller URL pattern and cover static resources on a common URL pattern like /resources/*, /static/*, etc with help of a servlet filter. See also How to prevent static resources from being handled by front controller servlet which is mapped on /*. Noted should be that Spring MVC has a builtin static resource servlet, so that's why you could map its front controller on / if you configure a common URL pattern for static resources in Spring. See also How to handle static content in Spring MVC?

FWIW, Codegear C++Builder doesn't destruct in the expected order according to the standard.

C:\> sample.exe 1 2
Created in foo
Created in if
Destroyed in foo
Destroyed in if

... which is another reason not to rely on the destruction order!

They are extension methods. Welcome to a whole new fluent world. :)

You can install Kafkacat tool on your machine

For example on Ubuntu You can install it using

apt-get install kafkacat

once kafkacat is installed then you can use following command to connect it

kafkacat -b <your-ip-address>:<kafka-port> -t test-topic

• Replace <your-ip-address> with your machine ip
• <kafka-port> can be replaced by the port on which kafka is running. Normally it is 9092

once you run the above command and if kafkacat is able to make the connection then it means that kafka is up and running

To avoid exceptions killing your app you should catch those exceptions and treat them the way you wish, defining the behavior for you app on those situations where the id is not found.

begin
  current_user.comments.find(ids)
rescue
  #do something in case of exception found
end

Here's more info on exceptions in ruby.

There are several ways to do it, but here is one solution (for 4 columns).

string[] row1 = { "s1", "s2", "s3" };
listView1.Items.Add("Column1Text").SubItems.AddRange(row1);

And a more verbose way is here:

ListViewItem item1 = new ListViewItem("Something");
item1.SubItems.Add("SubItem1a");
item1.SubItems.Add("SubItem1b");
item1.SubItems.Add("SubItem1c");

ListViewItem item2 = new ListViewItem("Something2");
item2.SubItems.Add("SubItem2a");
item2.SubItems.Add("SubItem2b");
item2.SubItems.Add("SubItem2c");

ListViewItem item3 = new ListViewItem("Something3");
item3.SubItems.Add("SubItem3a");
item3.SubItems.Add("SubItem3b");
item3.SubItems.Add("SubItem3c");

ListView1.Items.AddRange(new ListViewItem[] {item1,item2,item3});

info = data[:min(len(data), 75)

You could do a

mysqlimport --columns='head -n 1 $yourfile' --ignore-lines=1 dbname $yourfile`

That is, if your file is comma separated and is not semi-colon separated. Else you might need to sed through it too.

You could use window.open. Like this:

protected void btnNewEntry_Click(object sender, EventArgs e)
{ 
   Page.ClientScript.RegisterStartupScript(
   this.GetType(),"OpenWindow","window.open('YourURL','_newtab');",true);
}

You can easily write the method to do that :

  public static String toCamelCase(final String init) {
    if (init == null)
        return null;

    final StringBuilder ret = new StringBuilder(init.length());

    for (final String word : init.split(" ")) {
        if (!word.isEmpty()) {
            ret.append(Character.toUpperCase(word.charAt(0)));
            ret.append(word.substring(1).toLowerCase());
        }
        if (!(ret.length() == init.length()))
            ret.append(" ");
    }

    return ret.toString();
}

There only two things that MapReduce does NATIVELY: Sort and (implemented by sort) scalable GroupBy.

Most of applications and Design Patterns over MapReduce are built over these two operations, which are provided by shuffle and sort.

tl;dr:

• commit() writes the data synchronously (blocking the thread its called from). It then informs you about the success of the operation.
• apply() schedules the data to be written asynchronously. It does not inform you about the success of the operation.
• If you save with apply() and immediately read via any getX-method, the new value will be returned!
• If you called apply() at some point and it's still executing, any calls to commit() will block until all past apply-calls and the current commit-call are finished.

More in-depth information from the SharedPreferences.Editor Documentation:

Unlike commit(), which writes its preferences out to persistent storage synchronously, apply() commits its changes to the in-memory SharedPreferences immediately but starts an asynchronous commit to disk and you won't be notified of any failures. If another editor on this SharedPreferences does a regular commit() while a apply() is still outstanding, the commit() will block until all async commits are completed as well as the commit itself.

As SharedPreferences instances are singletons within a process, it's safe to replace any instance of commit() with apply() if you were already ignoring the return value.

The SharedPreferences.Editor interface isn't expected to be implemented directly. However, if you previously did implement it and are now getting errors about missing apply(), you can simply call commit() from apply().

You could use module scope. Say you have a module called utils:

f_value = 'foo'

def f():
    return f_value

f_value is a module attribute that can be modified by any other module that imports it. As modules are singletons, any change to utils from one module will be accessible to all other modules that have it imported:

>> import utils
>> utils.f()
'foo'
>> utils.f_value = 'bar'
>> utils.f()
'bar'

Note that you can import the function by name:

>> import utils
>> from utils import f
>> utils.f_value = 'bar'
>> f()
'bar'

But not the attribute:

>> from utils import f, f_value
>> f_value = 'bar'
>> f()
'foo'

This is because you're labeling the object referenced by the module attribute as f_value in the local scope, but then rebinding it to the string bar, while the function f is still referring to the module attribute.

The accepted answer seems acceptable, except that CodeAnalysis/FxCop will complain about the fact that it's catching a general exception type.

Also, it seems the "is" operator might degrade performance slightly.

CA1800: Do not cast unnecessarily says to "consider testing the result of the 'as' operator instead", but if you do that, you'll be writing more code than if you catch each exception separately.

Anyhow, here's what I would do:

bool exThrown = false;

try
{
    // Something
}
catch (FormatException) {
    exThrown = true;
}
catch (OverflowException) {
    exThrown = true;
}

if (exThrown)
{
    // Something else
}

Use [NSIndexPath indexPathForRow:inSection:] to quickly create an index path.

Edit: In Swift 3:

let indexPath = IndexPath(row: rowIndex, section: sectionIndex)

Swift 5

IndexPath(row: 0, section: 0)

(the documentation for this is here: http://dev.mysql.com/doc/refman/5.0/en/select.html)

or:

$select = "SELECT * FROM table_name";

$export = mysql_query ( $select ) or die ( "Sql error : " . mysql_error( ) );

$fields = mysql_num_fields ( $export );

        if ( ( !isset( $value ) ) || ( $value == "" ) )
        {
            $value = "\t";

If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900

If your date is text and you need to convert it then DATEVALUE will do this:

"Atomic operation" means an operation that appears to be instantaneous from the perspective of all other threads. You don't need to worry about a partly complete operation when the guarantee applies.

I like to use the tr -s command for this

 ps aux | tr -s [:blank:] | cut -d' ' -f3

This squeezes all white spaces down to 1 space. This way telling cut to use a space as a delimiter is honored as expected.

You wanted to change the layout at runtime on button click. But that is not possible and as it has been rightly stated above, you need to restart the activity. You will come across a similar problem when u plan on changing the theme based on user's selection but it will not reflect in runtime. You will have to restart the activity.

Take a look at example E of this tutorial -> https://www.postgresqltutorial.com/postgresql-group-by/

You need to call the function on your GROUP BY instead of calling the name of the virtual attribute you created on select. I was doing what all the answers above recommended and I was getting a column 'year_month' does not exist error.

What worked for me was:

SELECT 
    date_trunc('month', created_at), 'MM/YYYY' AS month
FROM

GROUP BY 
    date_trunc('month', created_at)

Solution in ES6/TypeScript:

let d = new Date;
console.log(d, [`${d.getFullYear()}`, `0${d.getMonth()}`.substr(-2), `0${d.getDate()}`.substr(-2)].join("-"));

I had a similar problem where the SelectedItem-binding did not update when I selected something in the combobox. My problem was that I had to set UpdateSourceTrigger=PropertyChanged for the binding.

<ComboBox ItemsSource="{Binding SalesPeriods}" 
          SelectedItem="{Binding SelectedItem, UpdateSourceTrigger=PropertyChanged}" />

you can simply cast a string array to int array by:

var converted = arr.Select(int.Parse)

I just wanted to point out my answer since I know for loop is faster then $.each loop here it is:

just add class="required" to inputs you want to be required and then in jquery do:

$('#signup_form').submit(function(){
    var fields = $('input.required');
    for(var i=0;i<fields.length;i++){
        if($(fields[i]).val() != ''){
            //whatever
        }
    }
});

There are different ways to do that.

• I created the data frame to showcase the different techniques to filter your data.

df = pd.DataFrame({'Date':['01-Jun-13','03-Jun-13', '15-Aug-13', '20-Jan-14', '21-Feb-14'],

'abc':[100,-20,40,25,60],'xyz':[200,50,-5,15,80] })

• I separated months/year/day and seperated month-year as you explained.

def getMonth(s):
  return s.split("-")[1]

def getDay(s):
  return s.split("-")[0]

def getYear(s):
  return s.split("-")[2]

def getYearMonth(s):
  return s.split("-")[1]+"-"+s.split("-")[2]

• I created new columns: year, month, day and 'yearMonth'. In your case, you need one of both. You can group using two columns 'year','month' or using one column yearMonth

df['year']= df['Date'].apply(lambda x: getYear(x))
df['month']= df['Date'].apply(lambda x: getMonth(x))
df['day']= df['Date'].apply(lambda x: getDay(x))
df['YearMonth']= df['Date'].apply(lambda x: getYearMonth(x))

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
3  20-Jan-14   25   15   14   Jan  20    Jan-14
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• You can go through the different groups in groupby(..) items.

In this case, we are grouping by two columns:

for key,g in df.groupby(['year','month']):
    print key,g

Output:

('13', 'Jun')         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
('13', 'Aug')         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
('14', 'Jan')         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
('14', 'Feb')         Date  abc  xyz year month day YearMonth

In this case, we are grouping by one column:

for key,g in df.groupby(['YearMonth']):
    print key,g

Output:

Jun-13         Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13
Aug-13         Date  abc  xyz year month day YearMonth
2  15-Aug-13   40   -5   13   Aug  15    Aug-13
Jan-14         Date  abc  xyz year month day YearMonth
3  20-Jan-14   25   15   14   Jan  20    Jan-14
Feb-14         Date  abc  xyz year month day YearMonth
4  21-Feb-14   60   80   14   Feb  21    Feb-14

• In case you wanna access to specific item, you can use get_group

print df.groupby(['YearMonth']).get_group('Jun-13')

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

• Similar to get_group. This hack would help to filter values and get the grouped values.

This also would give the same result.

print df[df['YearMonth']=='Jun-13'] 

Output:

        Date  abc  xyz year month day YearMonth
0  01-Jun-13  100  200   13   Jun  01    Jun-13
1  03-Jun-13  -20   50   13   Jun  03    Jun-13

You can select list of abc or xyz values during Jun-13

print df[df['YearMonth']=='Jun-13'].abc.values
print df[df['YearMonth']=='Jun-13'].xyz.values

Output:

[100 -20]  #abc values
[200  50]  #xyz values

You can use this to go through the dates that you have classified as "year-month" and apply cretiria on it to get related data.

for x in set(df.YearMonth): 
    print df[df['YearMonth']==x].abc.values
    print df[df['YearMonth']==x].xyz.values

I recommend also to check this answer as well.

Specifying a flex attribute to the container worked for me:

.container {
    flex: 0 0 auto;
}

This ensures the height is set and doesn't grow either.

Using /proc/tty/drivers only indicates which tty drivers are loaded. If you're looking for a list of the serial ports check out /dev/serial, it will have two subdirectories: by-id and by-path.

EX:

# find . -type l
./by-path/usb-0:1.1:1.0-port0
./by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0

Thanks to this post: https://superuser.com/questions/131044/how-do-i-know-which-dev-ttys-is-my-serial-port

If you have a container running as root that runs a script (which you can't change) that needs access to the sudo command, you can simply create a new sudo script in your $PATH that calls the passed command.

e.g. In your Dockerfile:

RUN if type sudo 2>/dev/null; then \ 
     echo "The sudo command already exists... Skipping."; \
    else \
     echo -e "#!/bin/sh\n\${@}" > /usr/sbin/sudo; \
     chmod +x /usr/sbin/sudo; \
    fi

I did it like this.

$(document).ready(function(){
    $("#yourid").click(function(){
        $(this).load('@Url.Action("Details")');
    });
});

Details Method:

public IActionResult Details()
        {

            return PartialView("Your Partial View");
        }

Here is a simple code that I created in c that should fix your problem :

#include <conio.h>

int main()
{
  int y,n,oy,ly,td,a,month,mon_,d,days,down,up; // oy==ordinary year, td=total days, d=date

    printf("Enter the year,month,date: ");
    scanf("%d%d%d",&y,&month,&d);
    n= y-1; //here we subtracted one year because we have to find on a particular day of that year, so we will not count whole year.
    oy= n%4;

    if(oy==0) // for leap year
      {
         mon_= month-1;
         down= mon_/2;  //down means months containing 30 days.
           up= mon_-down; // up means months containing 31 days.
           if(mon_>=2)
             {
               days=(up*31)+((down-1)*30)+29+d; // here in down case one month will be of feb so we subtracted 1 and after that seperately
               td= (oy*365)+(ly*366)+days;      // added 29 days as it is the if block of leap year case.
             }
           if(mon_==1)
             {
               days=(up*31)+d;
               td= (oy*365)+(ly*366)+days;
             } 
           if(mon_==0)
             {
               days= d;
               td= (oy*365)+(ly*366)+days;
             }    
      }
    else
      {
         mon_= month-1;
         down= mon_/2;
           up= mon_-down;
           if(mon_>=2)
             {
               days=(up*31)+((down-1)*30)+28+d;
               td= (oy*365)+(ly*366)+days;
             }
           if(mon_==1)
             {
               days=(up*31)+d;
               td= (oy*365)+(ly*366)+days;
             } 
           if(mon_==0)
             {
               days= d;
               td= (oy*365)+(ly*366)+days;
             }    
      }  

    ly= n/4;
     a= td%7;

     if(a==0)
       printf("\nSunday");
     if(a==1)
       printf("\nMonday");
     if(a==2)
       printf("\nTuesday");
     if(a==3)
       printf("\nWednesday");
     if(a==4)
       printf("\nThursday");
     if(a==5)
       printf("\nFriday");
     if(a==6)
       printf("\nSaturday");
  return 0;

To get the execution time as a variable in your proc:

DECLARE @EndTime datetime
DECLARE @StartTime datetime 
SELECT @StartTime=GETDATE() 

-- Write Your Query


SELECT @EndTime=GETDATE()

--This will return execution time of your query
SELECT DATEDIFF(ms,@StartTime,@EndTime) AS [Duration in millisecs] 

AND see this

If you happen to already have an instance of your desired class, you can use the 'type' function to extract its class type and use this to construct a new instance:

class Something(object):
    def __init__(self, name):
        self.name = name
    def display(self):
        print(self.name)

one = Something("one")
one.display()
cls = type(one)
two = cls("two")
two.display()

this.getWindow().getDecorView().findViewById(android.R.id.content)

or

this.findViewById(android.R.id.content)

or

this.findViewById(android.R.id.content).getRootView()

It appears that powershell.exe does not fully evaluate script arguments when the -File parameter is used. In particular, the $false argument is being treated as a string value, in a similar way to the example below:

PS> function f( [bool]$b ) { $b }; f -b '$false'
f : Cannot process argument transformation on parameter 'b'. Cannot convert value 
"System.String" to type "System.Boolean", parameters of this type only accept 
booleans or numbers, use $true, $false, 1 or 0 instead.
At line:1 char:36
+ function f( [bool]$b ) { $b }; f -b <<<<  '$false'
    + CategoryInfo          : InvalidData: (:) [f], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,f

Instead of using -File you could try -Command, which will evaluate the call as script:

CMD> powershell.exe -NoProfile -Command .\RunScript.ps1 -Turn 1 -Unify $false
Turn: 1
Unify: False

As David suggests, using a switch argument would also be more idiomatic, simplifying the call by removing the need to pass a boolean value explicitly:

CMD> powershell.exe -NoProfile -File .\RunScript.ps1 -Turn 1 -Unify
Turn: 1
Unify: True

The accepted answer didn't work for me but the following did:

>PsExec.exe \\<SERVER FQDN> -u <DOMAIN\USER> -p <PASSWORD> /accepteula cmd 
    /c "powershell -noninteractive -command gci c:\"

Here's a way I am doing it after researching it for a while. I wanted to make a Laravel API endpoint that checks if a field is "in use", so the important information is: 1) which DB table? 2) what DB column? and 3) is there a value in that column that matches the search terms?

Knowing this, we can construct our associative array:

$SEARCHABLE_TABLE_COLUMNS = [
    'users' => [ 'email' ],
];

Then, we can set our values that we will check:

$table = 'users';
$column = 'email';
$value = '[email protected]';

Then, we can use array_key_exists() and in_array() with eachother to execute a one, two step combo and then act upon the truthy condition:

// step 1: check if 'users' exists as a key in `$SEARCHABLE_TABLE_COLUMNS`
if (array_key_exists($table, $SEARCHABLE_TABLE_COLUMNS)) {

    // step 2: check if 'email' is in the array: $SEARCHABLE_TABLE_COLUMNS[$table]
    if (in_array($column, $SEARCHABLE_TABLE_COLUMNS[$table])) {

        // if table and column are allowed, return Boolean if value already exists
        // this will either return the first matching record or null
        $exists = DB::table($table)->where($column, '=', $value)->first();

        if ($exists) return response()->json([ 'in_use' => true ], 200);
        return response()->json([ 'in_use' => false ], 200);
    }

    // if $column isn't in $SEARCHABLE_TABLE_COLUMNS[$table],
    // then we need to tell the user we can't proceed with their request
    return response()->json([ 'error' => 'Illegal column name: '.$column ], 400);
}

// if $table isn't a key in $SEARCHABLE_TABLE_COLUMNS,
// then we need to tell the user we can't proceed with their request
return response()->json([ 'error' => 'Illegal table name: '.$table ], 400);

I apologize for the Laravel-specific PHP code, but I will leave it because I think you can read it as pseudo-code. The important part is the two if statements that are executed synchronously.

array_key_exists() and in_array() are PHP functions.

source:

• https://php.net/manual/en/function.array-key-exists.php

• https://php.net/manual/en/function.in-array.php

The nice thing about the algorithm that I showed above is that you can make a REST endpoint such as GET /in-use/{table}/{column}/{value} (where table, column, and value are variables).

You could have:

$SEARCHABLE_TABLE_COLUMNS = [
    'accounts' => [ 'account_name', 'phone', 'business_email' ],
    'users' => [ 'email' ],
];

and then you could make GET requests such as:

GET /in-use/accounts/account_name/Bob's Drywall (you may need to uri encode the last part, but usually not)

GET /in-use/accounts/phone/888-555-1337

GET /in-use/users/email/[email protected]

Notice also that no one can do:

GET /in-use/users/password/dogmeat1337 because password is not listed in your list of allowed columns for user.

Good luck on your journey.

If you are desperate you can try this:

git clone ssh://[email protected]/path/to/project destination --depth=1

It will get your data, but you'll lose the history. I went with trial and error on my repo and --depth=10 worked, but --depth=50 gave me failure.

I also encountered this problem when I was working on my project. I really wish they provide an end api method. Anyway, This is how I did it: When you are uploading an image to Firebase storage, create an Object and pass this object to Firebase database at the same time. This object contains the download URI of the image.

trailsRef.putFile(file).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Uri downloadUri = taskSnapshot.getDownloadUrl();
            DatabaseReference myRef = database.getReference().child("trails").child(trail.getUnique_id()).push();
            Image img = new Image(trail.getUnique_id(), downloadUri.toString());
            myRef.setValue(img);
        }
    });

Later when you want to download images from a folder, you simply iterate through files under that folder. This folder has the same name as the "folder" in Firebase storage, but you can name them however you want to. I put them in separate thread.

 @Override
protected List<Image> doInBackground(Trail... params) {

    String trialId = params[0].getUnique_id();
    mDatabase = FirebaseDatabase.getInstance().getReference();
    mDatabase.child("trails").child(trialId).addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            images = new ArrayList<>();
            Iterator<DataSnapshot> iter = dataSnapshot.getChildren().iterator();
            while (iter.hasNext()) {
                Image img = iter.next().getValue(Image.class);
                images.add(img);
            }
            isFinished = true;
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });

Now I have a list of objects containing the URIs to each image, I can do whatever I want to do with them. To load them into imageView, I created another thread.

    @Override
protected List<Bitmap> doInBackground(List<Image>... params) {

    List<Bitmap> bitmaps = new ArrayList<>();

    for (int i = 0; i < params[0].size(); i++) {
        try {
            URL url = new URL(params[0].get(i).getImgUrl());
            Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
            bitmaps.add(bmp);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    return bitmaps;
}

This returns a list of Bitmap, when it finishes I simply attach them to ImageView in the main activity. Below methods are @Override because I have interfaces created and listen for completion in other threads.

    @Override
public void processFinishForBitmap(List<Bitmap> bitmaps) {
    List<ImageView> imageViews = new ArrayList<>();
    View v;
    for (int i = 0; i < bitmaps.size(); i++) {
        v = mInflater.inflate(R.layout.gallery_item, mGallery, false);
        imageViews.add((ImageView) v.findViewById(R.id.id_index_gallery_item_image));
        imageViews.get(i).setImageBitmap(bitmaps.get(i));
        mGallery.addView(v);
    }
}

Note that I have to wait for List Image to be returned first and then call thread to work on List Bitmap. In this case, Image contains the URI.

    @Override
public void processFinish(List<Image> results) {
    Log.e(TAG, "get back " + results.size());

    LoadImageFromUrlTask loadImageFromUrlTask =  new LoadImageFromUrlTask();
    loadImageFromUrlTask.delegate = this;
    loadImageFromUrlTask.execute(results);
}

Hopefully someone finds it helpful. It will also serve as a guild line for myself in the future too.

CSS Reset is best way to use for this issue. Right now in reset we are using p and in need bases you can add any number of tags by come separated.

p {
    margin:0;
    padding:0;
}

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

CSS:

#box{
    border:1px solid black;
    position:relative;
}
#overlay{
    position:absolute;
    top:0px;
    left:0px;
    bottom:0px;
    right:0px;
    background-color:rgba(255,255,0,0.5);
}

Hardiff.com is pretty useful tool. It allows you to compare one or more .har files.

import csv
with open(file_path, 'a') as outcsv:   
    #configure writer to write standard csv file
    writer = csv.writer(outcsv, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL, lineterminator='\n')
    writer.writerow(['number', 'text', 'number'])
    for item in list:
        #Write item to outcsv
        writer.writerow([item[0], item[1], item[2]])

Reorient your mental model of the functionality of "CASCADE" by thinking of adding a FK to an already existing cascade (i.e. a waterfall). The source of this waterfall is a primary key (PK). Deletes flow down.

So if you define a FK's on_delete as "CASCADE," you're adding this FK's record to a cascade of deletes originating from the PK. The FK's record may participate in this cascade or not ("SET_NULL"). In fact, a record with a FK may even prevent the flow of the deletes! Build a dam with "PROTECT."

[Test double types]

Mock vs Spy

Mock is a bare double object. This object has the same methods signatures but realisation is empty and return default value - 0 and null

Spy is a cloned double object. New object is cloned based on a real object but you have a possibility to mock it

class A {
    String foo1() {
        foo2();
        return "RealString_1";
    }

    String foo2() {
        return "RealString_2";
    }

    void foo3() { foo4(); }

    void foo4() { }
}

@Test
public void testMockA() {
    //given
    A mockA = Mockito.mock(A.class);
    Mockito.when(mockA.foo1()).thenReturn("MockedString");

    //when
    String result1 = mockA.foo1();
    String result2 = mockA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals(null, result2);

i know i am late for this answer but the correct answer seems to be

See :help getcompletion():

:echo getcompletion('', 'color')

which you can assign to a variable:

:let foo = getcompletion('', 'color')

or use in an expression register:

:put=getcompletion('', 'color')

This is not my answer, this solution is provided by u/romainl in this post on reddit.

You can do something like this:

var radios = document.getElementsByName('genderS');_x000D_
_x000D_
for (var i = 0, length = radios.length; i < length; i++) {_x000D_
  if (radios[i].checked) {_x000D_
    // do whatever you want with the checked radio_x000D_
    alert(radios[i].value);_x000D_
_x000D_
    // only one radio can be logically checked, don't check the rest_x000D_
    break;_x000D_
  }_x000D_
}

<label for="gender">Gender: </label>_x000D_
<input type="radio" name="genderS" value="1" checked="checked">Male</input>_x000D_
<input type="radio" name="genderS" value="0">Female</input>

Edit: Thanks HATCHA and jpsetung for your edit suggestions.

I'd like to add another use case for an internal struct/class and its usability. An inner struct is often used to declare a data only member of a class that packs together relevant information and as such we can enclose it all in a struct instead of loose data members lying around.

The inner struct/class is but a data only compartment, ie it has no functions (except maybe constructors).

#include <iostream>

class E
{
    // E functions..
public:
    struct X
    {
        int v;
        // X variables..
    } x;
    // E variables..
};

int main()
{
    E e;
    e.x.v = 9;
    std::cout << e.x.v << '\n';
    
    E e2{5};
    std::cout << e2.x.v << '\n';

    // You can instantiate an X outside E like so:
    //E::X xOut{24};
    //std::cout << xOut.v << '\n';
    // But you shouldn't want to in this scenario.
    // X is only a data member (containing other data members)
    // for use only inside the internal operations of E
    // just like the other E's data members
}

This practice is widely used in graphics, where the inner struct will be sent as a Constant Buffer to HLSL. But I find it neat and useful in many cases.

Use the old-school DOS command:

rd /s <dir>

The solution of Rob Stevenson-Legget is slow because he doesn't bind his values but he uses string.Format( ).

When you ask Oracle to execute a sql statement it starts with calculating the has value of this statement. After that it looks in a hash table whether it already knows this statement. If it already knows it statement it can retrieve its execution path from this hash table and execute this statement really fast because Oracle has executed this statement before. This is called the library cache and it doesn't work properly if you don't bind your sql statements.

For example don't do:

int n;

    for (n = 0; n < 100000; n ++)
    {
      mycommand.CommandText = String.Format("INSERT INTO [MyTable] ([MyId]) VALUES({0})", n + 1);
      mycommand.ExecuteNonQuery();
    }

but do:

      OracleParameter myparam = new OracleParameter();
      int n;

      mycommand.CommandText = "INSERT INTO [MyTable] ([MyId]) VALUES(?)";
      mycommand.Parameters.Add(myparam);

      for (n = 0; n < 100000; n ++)
      {
        myparam.Value = n + 1;
        mycommand.ExecuteNonQuery();
      }

Not using parameters can also cause sql injection.

In the general case, the answer is No.

However, you can set the debugger to break at the point where the exception is first thrown. At that time, the key which was not present will be accessible as a value in the call stack.

In Visual Studio, this option is located here:

Debug → Exceptions... → Common Language Runtime Exceptions → System.Collections.Generic

There, you can check the Thrown box.

For more specific instances where information is needed at runtime, provided your code uses IDictionary<TKey, TValue> and not tied directly to Dictionary<TKey, TValue>, you can implement your own dictionary class which provides this behavior.

I've had to do this recently on the API 23 emulator, and followed this guide. It works for API 23 emulator, so you shouldn't have a problem.

Note: All credit goes to the author of the linked blog post (pyoor). I'm just posting it here in case the link breaks for any reason.

Download the GAPPS Package

Next we need to pull down the appropriate Google Apps package that matches our Android AVD version. In this case we’ll be using the 'gapps-lp-20141109-signed.zip' package. You can download that file from BasketBuild here.

[pyoor@localhost]$ md5sum gapps-lp-20141109-signed.zip
367ce76d6b7772c92810720b8b0c931e gapps-lp-20141109-signed.zip

In order to install Google Play, we’ll need to push the following 4 APKs to our AVD (located in ./system/priv-app/):

GmsCore.apk, GoogleServicesFramework.apk, GoogleLoginService.apk, Phonesky.apk

[pyoor@localhost]$ unzip -j gapps-lp-20141109-signed.zip \
system/priv-app/GoogleServicesFramework/GoogleServicesFramework.apk \
system/priv-app/GoogleLoginService/GoogleLoginService.apk \
system/priv-app/Phonesky/Phonesky.apk \
system/priv-app/GmsCore/GmsCore.apk -d ./

Push APKs to the Emulator

With our APKs extracted, let’s launch our AVD using the following command.

[pyoor@localhost tools]$ ./emulator @<YOUR_DEVICE_NAME> -no-boot-anim

This may take several minutes the first time as the AVD is created. Once started, we need to remount the AVDs system partition as read/write so that we can push our packages onto the device.

[pyoor@localhost]$ cd ~/android-sdk/platform-tools/
[pyoor@localhost platform-tools]$ ./adb remount

Next, push the APKs to our AVD:

[pyoor@localhost platform-tools]$ ./adb push GmsCore.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push GoogleServicesFramework.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push GoogleLoginService.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push Phonesky.apk /system/priv-app

Profit!

And finally, reboot the emualator using the following commands:

[pyoor@localhost platform-tools]$ ./adb shell stop && ./adb shell start

Once the emulator restarts, we should see the Google Play package appear within the menu launcher. After associating a Google account with this AVD we now have a fully working version of Google Play running under our emulator.

In PCRE \R matches \n, \r and \r\n.

What would happen, if you want to create many such records ones (to register 10 users, not just one)? I find the following solution (just 5 queryes):

Step I: Create temporary table to store new data.

CREATE TEMPORARY TABLE tmp (id bigint(20) NOT NULL, ...)...;

Next, fill this table with values.

INSERT INTO tmp (username, password, bio, homepage) VALUES $ALL_VAL

Here, instead of $ALL_VAL you place list of values: ('test1','test1','bio1','home1'),...,('testn','testn','bion','homen')

Step II: Send data to 'user' table.

INSERT IGNORE INTO users (username, password)
SELECT username, password FROM tmp;

Here, "IGNORE" can be used, if you allow some users already to be inside. Optionaly you can use UPDATE similar to step III, before this step, to find whom users are already inside (and mark them in tmp table). Here we suppouse, that username is declared as PRIMARY in users table.

Step III: Apply update to read all users id from users to tmp table. THIS IS ESSENTIAL STEP.

UPDATE tmp JOIN users ON tmp.username=users.username SET tmp.id=users.id

Step IV: Create another table, useing read id for users

INSERT INTO profiles (userid, bio, homepage) 
SELECT id, bio, homepage FROM tmp

These lines will convert the arguments of a CLI call like php myfile.php "type=daily&foo=bar" into the well known $_GET-array:

if (!empty($argv[1])) {
  parse_str($argv[1], $_GET);
}

Though it is rather messy to overwrite the global $_GET-array, it converts all your scripts quickly to accept CLI arguments.

See parse_str for details.

CSS font-stretch is now supported in all major browsers (except iOS Safari and Opera Mini). It is not easy to find a common font-family that supports expanding fonts, but it is easy to find fonts that support condensing, for example:

font-stretch: condense;
font-family: sans-serif, "Helvetica Neue", "Lucida Grande", Arial;

If you're open to a Perl solution...

perl -ane 'print "$F[0] $F[1]\n"' file

These command-line options are used:

• -n loop around every line of the input file, do not automatically print every line

• -a autosplit mode – split input lines into the @F array. Defaults to splitting on whitespace

• -e execute the following perl code

Write a Boolean function that checks the regex and use apply on the column

foo[foo['b'].apply(regex_function)]

yield can also be used to eliminate callback hell, with a coroutine framework.

function start(routine, data) {
    result = routine.next(data);
    if(!result.done) {
        result.value(function(err, data) {
            if(err) routine.throw(err); // continue next iteration of routine with an exception
            else start(routine, data);  // continue next iteration of routine normally
        });
    }
}

// with nodejs as 'node --harmony'
fs = require('fs');
function read(path) {
    return function(callback) { fs.readFile(path, {encoding:'utf8'}, callback); };
}

function* routine() {
    text = yield read('/path/to/some/file.txt');
    console.log(text);
}

// with mdn javascript 1.7
http.get = function(url) {
    return function(callback) { 
        // make xhr request object, 
        // use callback(null, resonseText) on status 200,
        // or callback(responseText) on status 500
    };
};

function* routine() {
    text = yield http.get('/path/to/some/file.txt');
    console.log(text);
}

// invoked as.., on both mdn and nodejs

start(routine());

I think the NSURLSession api fits better in this situation. Because if you write swift code your project target is at least iOS 7 and iOS 7 supports NSURLSession api. Anyway here is the code

let url = "YOUR_URL"

NSURLSession.sharedSession().dataTaskWithURL(NSURL(string: url)) { data, response, error in
    // Handle result
}.resume()

The reason to that might be the 2 lines in eclipse.ini

--launcher.library
C:\Users\UserName\.p2\pool\plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.400.v20160518-1444

for my case the reason was admin privilages so I had to move the folder from the path specified in ini to my eclipse plugins and change path in ini to :

plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.400.v20160518-1444

The 'file' protocol is not a network protocol. Therefore file://192.168.1.57/~User/2ndFile.html simply does not make much sense.

Question is how you load the first file. Is that really done using a web server? Does not really sound like. If it is, then why not use the same protocol, most likely http? You cannot expect to simply switch the protocol and use two different protocols the same way...

I suspect the first file is really loaded using the apache server at all, but simply by opening the file? href="2ndFile.html" simply works because it uses a "relative url". This makes the browser use the same protocol and path as where he got the first (current) file from.

To convert seconds time stamp to millisecond time stamp. You could use the TimeUnit API and neat like this.

long milliSecondTimeStamp = MILLISECONDS.convert(secondsTimeStamp, SECONDS)

Although you can run FTP commands using WebSockets, the simpler solution is listing your files using opendir in server side (PHP), and "spitting" it into the HTML source-code, so it will be available to client side.

The following code will do just that,

Optionally -

• use <a> tag to present a link.

• query for more information using server side (PHP),

  for example a file size,

_{PHP filesize TIP:   also you can easily overcome the 2GB limit of PHP's filesize using: AJAX + HEAD request + .htaccess rule to allow Content-Length access from client-side.}

Thread class defines several methods that can be overriden by the the extending class. But to create a thread we must override the run() method. Same applies to Runnable as well.

However Runnable is a preferred method of creating a thread. The primary reasons are:

1. Since Runnable is an interface, you can extend other classes. But if you extend Thread then that option is gone.

2. If you are not modifying or enhancing a whole lot of Thread functionalities and extending the Thread class is not a preferred way.

In VS 2012, just go to View > Class View...then you get the Class View GUI in the main tab area. Now, drag this over to the side dock and you have the exact same layout as you would in Eclipse.

Since Laravel 5.5 the @switch is built into the Blade. Use it as shown below.

@switch($login_error)
    @case(1)
        <span> `E-mail` input is empty!</span>
        @break

    @case(2)
        <span>`Password` input is empty!</span>
        @break

    @default
        <span>Something went wrong, please try again</span>
@endswitch

Older Answer

Unfortunately Laravel Blade does not have switch statement. You can use Laravel if else approach or use use plain PHP switch. You can use plain PHP in blade templates like in any other PHP application. Starting from Laravel 5.2 and up use @php statement.

Option 1:

@if ($login_error == 1)
    `E-mail` input is empty!
@elseif ($login_error == 2)
    `Password` input is empty!
@endif

create table payment(
    user_id int(11),
    account int(11) not null,
    zip int(11) not null,
    dt date not null
);

insert into payment values
(1,123,55555,'2009-12-12'),
(1,123,66666,'2009-12-12'),
(1,123,77777,'2009-12-13'),
(2,456,77777,'2009-12-14'),
(2,456,77777,'2009-12-14'),
(2,789,77777,'2009-12-14'),
(2,789,77777,'2009-12-14');

select foo.user_id, foo.cnt from
(select user_id,count(account) as cnt, dt from payment group by account, dt) foo
where foo.cnt > 1;

s = s.substring(0, Math.min(s.length(), 10));

Using Math.min like this avoids an exception in the case where the string is already shorter than 10.

Notes:

1. The above does real trimming. If you actually want to replace the last three (!) characters with dots if it truncates, then use Apache Commons StringUtils.abbreviate.

2. For typical implementations of String, s.substring(0, s.length()) will return s rather than allocating a new String.

3. This may behave incorrectly¹ if your String contains Unicode codepoints outside of the BMP; e.g. Emojis. For a (more complicated) solution that works correctly for all Unicode code-points, see @sibnick's solution.

^{1 - A Unicode codepoint that is not on plane 0 (the BMP) is represented as a "surrogate pair" (i.e. two char values) in the String. By ignoring this, we might trim to fewer than 10 code points, or (worse) truncate in the middle of a surrogate pair. On the other hand, String.length() is no longer an ideal measure of Unicode text length, so trimming based on it may be the wrong thing to do.}

to add parameter to post urls (to perma-links), i use this:

add_filter( 'post_type_link', 'append_query_string', 10, 2 );
function append_query_string( $url, $post ) 
{
    return add_query_arg('my_pid',$post->ID, $url);
}

output:

http://yoursite.com/pagename?my_pid=12345678

Here is an easy way.

Open the connection window, click on the Server name dropdown, and hover over the connection string you want to delete, then press delete.

None of the previous answers efficiently provide the required output, which is a tuple of lists, rather than a list of tuples. For the former, you can use tuple with map. Here's the difference:

res1 = list(zip(*original))              # [('a', 'b', 'c', 'd'), (1, 2, 3, 4)]
res2 = tuple(map(list, zip(*original)))  # (['a', 'b', 'c', 'd'], [1, 2, 3, 4])

In addition, most of the previous solutions assume Python 2.7, where zip returns a list rather than an iterator.

For Python 3.x, you will need to pass the result to a function such as list or tuple to exhaust the iterator. For memory-efficient iterators, you can omit the outer list and tuple calls for the respective solutions.

I find this to be a bit safer and easier to rely on for simple moves that exclude certain files or directories.

ls -1 | grep -v ^$EXCLUDE | xargs -I{} mv {} $TARGET

This is my plugin for that case:

 (function( $ ) {
    $.fn.numbers = function(options) {
      $(this).keypress(function(evt){
          var setting = $.extend( {
                'digits' : 8
              }, options);
          if($(this).val().length > (setting.digits - 1) && evt.which != 8){
              evt.preventDefault(); 
          }
          else{
              if(evt.which < 48 || evt.which > 57){
                if(evt.keyCode != 8){
                    evt.preventDefault();  
                }
              }
          }
      });
    };
  })( jQuery );

Use:

 $('#limin').numbers({digits:3});
 $('#limax').numbers();

    classpath 'com.google.gms:google-services:4.1.0'

has a problem. instead use:

    classpath 'com.google.gms:google-services:4.2.0'

If you're using Windows 10, it is built into the Linux subsystem feature. Just launch a Bash prompt (press the Windows key, then type bash and choose "Bash on Ubuntu on Windows"), cd to the directory you want to make and type make.

FWIW, the Windows drives are found in /mnt, e.g. C:\ drive is /mnt/c in Bash.

If Bash isn't available from your start menu, here are instructions for turning on that Windows feature (64-bit Windows only):

You can run the sleep command before your ExecStart with ExecStartPre :

[Service]

In short: no. The first problem is access to the filesystem, which in most browsers is set to no by default due to security reasons. Modern browsers sometimes support minimalistic storage in the form of a database, or you can ask the user to enable file access.

If you have access to the filesystem then saving as HTML is not that hard (see the file object in the JS documentation) - but PDF is not so easy. PDF is a quite advanced file-format that really is ill suited for Javascript. It requires you to write information in datatypes not directly supported by Javascript, such as words and quads. You also need to pre-define a dictionary lookup system that must be saved to the file. Im sure someone could make it work, but the effort and time involved would be better spent learning C++ or Delphi.

HTML export however should be possible if the user gives you non restricted access

Or you can style it with pixels.

 .big-checkbox {width: 30px; height: 30px;}

Very annoying, no cookie file exmpale on the official website https://ec.haxx.se/http/http-cookies.

Finnaly, I find it does not work, if your file content is just copyied like this

foo1=bar;foo2=bar2

I gusess the format must looks the style said by @Agustí Sánchez . You can test it by -c to create a cookie file on a website.

So try this way, it works

curl -H "Cookie:`cat ./my.cookie`"   http://xxxx.com

You can just copy the cookie from chrome console network tab.

Below is a workaround demo image of ; Uncheck Offline work option by going to:

File -> Settings -> Build, Execution, Deployment -> Gradle

If above workaround not works then try this:

1. Open the build.gradle file for your application.

2. Make sure that the repositories section includes a maven section with the "https://maven.google.com" endpoint. For example:

   allprojects {
        repositories {
            jcenter()
            maven {
                url "https://maven.google.com"
            }
        }
   }
   

3. Add the support library to the dependencies section. For example, to add the v4 core-utils library, add the following lines:

   dependencies {
       ...
       compile "com.android.support:support-core-utils:27.1.0"
   }
   

Caution: Using dynamic dependencies (for example, palette-v7:23.0.+) can cause unexpected version updates and regression incompatibilities. We recommend that you explicitly specify a library version (for example, palette-v7:27.1.0).

Manifest Declaration Changes

Specifically, you should update the android:minSdkVersion element of the <uses-sdk> tag in the manifest to the new, lower version number, as shown below:

<uses-sdk
  android:minSdkVersion="14"
  android:targetSdkVersion="23" />

If you are using Gradle build files, the minSdkVersion setting in the build file overrides the manifest settings.

apply plugin: 'com.android.application'

android {
   ...
      defaultConfig {
            minSdkVersion 16
            ...
        }
        ...
    }

Following Android Developer Library Support.

You can use expect scripts instaed of bash. Below example show how to telnex into an embedded board having no password

#!/usr/bin/expect

set ip "<ip>"

spawn "/bin/bash"
send "telnet $ip\r"
expect "'^]'."
send "\r"
expect "#"
sleep 2

send "ls\r"
expect "#"

sleep 2
send -- "^]\r"
expect "telnet>"
send  "quit\r"
expect eof

$("#frame").click(function () { 
    this.src="http://www.google.com/";
});

Sometimes plain JavaScript is even cooler and faster than jQuery ;-)

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

Autoplay works only with /v/ instead of /embed/, so change the src to:

src="//www.youtube.com/v/qUJYqhKZrwA?autoplay=1&showinfo=0&controls=0"

Just by using select select you can select particular columns, give them readable names and cast them. For example like this:

spark.read.csv(path).select(
          '_c0.alias("stn").cast(StringType),
          '_c1.alias("wban").cast(StringType),
          '_c2.alias("lat").cast(DoubleType),
          '_c3.alias("lon").cast(DoubleType)
        )
          .where('_c2.isNotNull && '_c3.isNotNull && '_c2 =!= 0.0 && '_c3 =!= 0.0)

You need either

• A unique index on Title in BookTitle
• An ISBN column in BookCopy and the FK is on both columns

A foreign key needs to uniquely identify the parent row: you currently have no way to do that because Title is not unique.

To do this:

1. open terminal

2. type in the terminal: nano ; which is a text editor available for the terminal. when you do this. something like this would appear.

3. here you can type in your C program

4. type in control(^) + x -> which means to exit.

5. save the file by typing in y to save the file

6. write the file name; e.g. helloStack.c (don't forget to add .c)

7. when this appears, type in gcc helloStack.c

8. then ./a.out: this should give you your result!!

The "loginVo.htmlBody(messageBodyPart);" will contain the html formatted designed information, but in mail does not receive it.

solution is easy:

replace

            140 < df['systolic blood pressure'] < 160 &
            90  < df['dyastolic blood pressure'] < 100 &

            95  < df['pulse oximetry'] < 100
            , "excellent", "critical")

I've ran into the same problem recently. After finding the correct path to the pyuic4 file using the file finder I've ran:

C:\Users\ricckli.qgis2\python\plugins\qgis2leaf>C:\OSGeo4W64\bin\pyuic4 -o ui_q gis2leaf.py ui_qgis2leaf.ui

As you can see my ui file was placed in this folder...

QT Creator was installed separately and the pyuic4 file was placed there with the OSGEO4W installer
