I guess inspect is the best way to do this. For example:

import inspect
def bar():
    print("My name is", inspect.stack()[0][3])

I had the same problem and I Changed this

<configuration>
    <source>1.7</source>
    <target>1.7</target>
 </configuration>

here 1.7 is my JDK version.it was solved.

You can try this:

HTML

<div class="social">
    <div class="socialIcon"><img src="images/facebook.png" alt="Facebook" /></div>
    <div class="socialText">Find me on Facebook</div>
</div>

CSS CODE

.social {
  width:330px;
  height:75px;
  float:right;
  text-align:left;
  padding:10px 0;
  border-bottom:dotted 1px #6d6d6d;
}
.social .socialIcon{
  padding-top:0;
}
.social .socialText{
  border:0;
}

To add multiple class in the same element you can use the following format:

<div class="class1 class2 class3"></div>

DEMO

When trying to enter continuous text (say, a query) do not put commas at the end of the line or you will get a list of strings instead of one long string:

queryText= "SELECT * FROM TABLE1 AS T1"\
"JOIN TABLE2 AS T2 ON T1.SOMETHING = T2.SOMETHING"\
"JOIN TABLE3 AS T3 ON T3.SOMETHING = T2.SOMETHING"\
"WHERE SOMETHING BETWEEN <WHATEVER> AND <WHATEVER ELSE>"\
"ORDER BY WHATEVERS DESC"

kinda like that.

There is a comment like this from acgtyrant, sorry, didn't see that. :/

This solution is deprecated

failure|fail|error() is deprecated and will be removed in 2.1, please use promise-style instead.

so you have to use

Project.update(

    // Set Attribute values 
    {
        title: 'a very different title now'
    },

    // Where clause / criteria 
    {
        _id: 1
    }

).then(function() {

    console.log("Project with id =1 updated successfully!");

}).catch(function(e) {
    console.log("Project update failed !");
})

And you can use .complete() as well

Regards

Type in console as root:

apt-get update && apt-get install php5-curl

or with sudo:

sudo apt-get update && sudo apt-get install php5-curl

Sorry I missread.

1st, check your DNS config and if you can ping any host at all,

ping google.com
ping zm.archive.ubuntu.com

If it does not work, check /etc/resolv.conf or /etc/network/resolv.conf, if not, change your apt-source to a different one.

/etc/apt/sources.list

You should not use Ubuntu sources on Debian and vice versa.

Marked answer might be the correct one, according to subversion cleanup. But the error is definitely a generic one, which led me here, this question page.

Our project has the dependency System.Data.SQLite and the error message was the same:

database disk image is malformed

In my case, I've executed following check script and the followings via SQLiteStudio 3.1.1.

pragma integrity_check

(I don't have any idea if these statistics would help, but I'm going to share them anyway...)

The DataBase file is being used on everyday usage for 1.5 year, via the connection journal mode on Memory, and was about 750 MB large. There were approximately 140K records per table and 6 tables was this large.

After the execution of Integrity Check script, 11 rows was returned after 30 minutes of execution time.

wrong # of entries in index sqlite_autoindex_MyTableName_1
wrong # of entries in index MyOtherTableAndOrIndexName_1
wrong # of entries in index sqlite_autoindex_MyOtherTableAndOrIndexName_2
etc...

All the results were about the indexes. Following-up the re-building each indexes, my problem was resolved.

reindex sqlite_autoindex_MyTableName_1;
reindex MyOtherTableAndOrIndexName_1;
reindex sqlite_autoindex_MyOtherTableAndOrIndexName_2;

After re-indexing, the integrity check resulted "ok".

I've got this error last year, and I was restored the DB from the backup, and then re-committed all the changes, which was a real nightmare...

Now there is a problem, if you have package-lock.json with npm 5+. You have to remove it before use of npm install --production.

how to convert JTextField to string and string to JTextField in java

If you mean how to get and set String from jTextField then you can use following methods:

String str = jTextField.getText() // get string from jtextfield

and

jTextField.setText(str)  // set string to jtextfield
//or
new JTextField(str)     // set string to jtextfield

You should check JavaDoc for JTextField

"What's the use of using join()?" you say. Really, it's the same answer as "what's the use of closing files, since python and the OS will close my file for me when my program exits?".

It's simply a matter of good programming. You should join() your threads at the point in the code that the thread should not be running anymore, either because you positively have to ensure the thread is not running to interfere with your own code, or that you want to behave correctly in a larger system.

You might say "I don't want my code to delay giving an answer" just because of the additional time that the join() might require. This may be perfectly valid in some scenarios, but you now need to take into account that your code is "leaving cruft around for python and the OS to clean up". If you do this for performance reasons, I strongly encourage you to document that behavior. This is especially true if you're building a library/package that others are expected to utilize.

There's no reason to not join(), other than performance reasons, and I would argue that your code does not need to perform that well.

# Method 1
f = open("Path/To/Your/File.txt", "w")   # 'r' for reading and 'w' for writing
f.write("Hello World from " + f.name)    # Write inside file 
f.close()                                # Close file 

# Method 2
with open("Path/To/Your/File.txt", "w") as f:   # Opens file and casts as f 
    f.write("Hello World form " + f.name)       # Writing
    # File closed automatically

There are many more methods but these two are most common. Hope this helped!

The code that all the answers have will make the cells padding equal to zero instead of the default value. I saw the problem in iOS 11 iPad Pro 12''

But I have one solution ("dirty hack") that is to make an empty section that will make separator line to hide.

Here is the code I used:

typedef enum PXSettingsTableSections {
    PXSettingSectionInvite = 0,
    PXSettingSectionAccount,
    PXSettingSectionPrivacy,
    PXSettingSectionCreation,
    PXSettingSectionTest,
    PXSettingSectionAboutHide,  // invisble section just to hide separator Line
    PXSettingSectionFooterHide, // invisble section just to hide separator Line
    PXSettingSectionNumItems,
} PXSettingsTableSectionsType;

        case PXSettingSectionPrivacy: return 1;
        case PXSettingSectionCreation: return 2;
        case PXSettingSectionTest: return 3;
        case PXSettingSectionAboutHide: return 3;

    }
}

    }
    return nil;
}

        // [UIColor clearColor] will not work 
        [header.contentView setBackgroundColor:[UIColor whiteColor]];
    }
}


- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section

            return self.inviteCell;
        case PXSettingSectionAccount:
            if (isSocialLogin) {
                return self.myWalletCell;
            }
            switch(indexPath.row)
            {
                case 0: return self.changePasswordCell;
                case 1: return self.myWalletCell;
            }
        case PXSettingSectionPrivacy:
            switch(indexPath.row)
        {

    return self.emptyCell;
}

Beside all the above hints like track by and smaller loops, this one also helped me a lot

<span ng-bind="::stock.name"></span>

this piece of code would print the name once it has been loaded, and stop watching it after that. Similarly, for ng-repeats, it could be used as

<div ng-repeat="stock in ::ctrl.stocks">{{::stock.name}}</div>

however it only works for AngularJS version 1.3 and higher. From http://www.befundoo.com/blog/optimizing-ng-repeat-in-angularjs/

Why to avoid using Session in WebAPI?

Performance, performance, performance!

There's a very good, and often overlooked reason why you shouldn't be using Session in WebAPI at all.

The way ASP.NET works when Session is in use is to serialize all requests received from a single client. Now I'm not talking about object serialization - but running them in the order received and waiting for each to complete before running the next. This is to avoid nasty thread / race conditions if two requests each try to access Session simultaneously.

Concurrent Requests and Session State

Access to ASP.NET session state is exclusive per session, which means that if two different users make concurrent requests, access to each separate session is granted concurrently. However, if two concurrent requests are made for the same session (by using the same SessionID value), the first request gets exclusive access to the session information. The second request executes only after the first request is finished. (The second session can also get access if the exclusive lock on the information is freed because the first request exceeds the lock time-out.) If the EnableSessionState value in the @ Page directive is set to ReadOnly, a request for the read-only session information does not result in an exclusive lock on the session data. However, read-only requests for session data might still have to wait for a lock set by a read-write request for session data to clear.

So what does this mean for Web API? If you have an application running many AJAX requests then only ONE is going to be able to run at a time. If you have a slower request then it will block all others from that client until it is complete. In some applications this could lead to very noticeably sluggish performance.

So you should probably use an MVC controller if you absolutely need something from the users session and avoid the unncesessary performance penalty of enabling it for WebApi.

You can easily test this out for yourself by just putting Thread.Sleep(5000) in a WebAPI method and enable Session. Run 5 requests to it and they will take a total of 25 seconds to complete. Without Session they'll take a total of just over 5 seconds.

(This same reasoning applies to SignalR).

this happened again around last quarter of 2017 . greasemonkey firing too late . after domcontentloaded event already been fired.

what to do:

• i used @run-at document-start instead of document-end
• updated firefox to 57.

from : https://github.com/greasemonkey/greasemonkey/issues/2769

Even as a (private) script writer I'm confused why my script isn't working.

The most likely problem is that the 'DOMContentLoaded' event is fired before the script is run. Now before you come back and say @run-at document-start is set, that directive isn't fully supported at the moment. Due to the very asynchronous nature of WebExtensions there's little guarantee on when something will be executed. When FF59 rolls around we'll have #2663 which will help. It'll actually help a lot of things, debugging too.

well first of all you need to install this packege below:

sudo apt install ipython
jupyter nbconvert --to script [YOUR_NOTEBOOK].ipynb

two option is avaliable either --to python or --to=python mine was like this works fine: jupyter nbconvert --to python while.ipynb

jupyter nbconvert --to python while.ipynb 

[NbConvertApp] Converting notebook while.ipynb to python [NbConvertApp] Writing 758 bytes to while.py

pip3 install ipython

if it does not work for you try, by pip3.

pip3 install ipython

I'm not familiar with SSRS, but you can get the beginning and end of the previous month in VB.Net using the DateTime constructor, like this:

Dim prevMonth As DateTime = yourDate.AddMonths(-1)

Dim prevMonthStart As New DateTime(prevMonth.Year, prevMonth.Month, 1)
Dim prevMonthEnd As New DateTime(prevMonth.Year, prevMonth.Month, DateTime.DaysInMonth(prevMonth.Year, prevMonth.Month))

(yourDate can be any DateTime object, such as DateTime.Today or #12/23/2003#)

If your Activity extends ListActivity, you can simply override the OnListItemClick() method like so:

/** {@inheritDoc} */
@Override  
protected void onListItemClick(ListView l, View v, int pos, long id) {  
    super.onListItemClick(l, v, pos, id);

    // TODO : Logic
}  

add Something like script.js?a=[random Number] with the Random number generated by PHP.

Have you tried expire=0, the pragma "no-cache" and "cache-control=NO-CACHE"? (I dunno what they say about Scripts).

It is bad practice to catch Exception -- it's just too broad, and you may miss something like a NullPointerException in your own code.

For most file operations, IOException is the root exception. Better to catch that, instead.

check this Twig Reference.

You can do it that simple:

{% if (a or b) %}
    ...
{% endif %}

HTTP/2 supports queries multiplexing, headers compression, priority and more intelligent packet streaming management. This results in reduced latency and accelerates content download on modern web pages.

More details here.

Because System.exit() is just another method to the compiler. It doesn't read ahead and figure out that the whole program will quit at that point (the JVM quits). Your OS or shell can read the integer that is passed back in the System.exit() method. It is standard for 0 to mean "program quit and everything went OK" and any other value to notify an error occurred. It is up to the developer to document these return values for any users.

return on the other hand is a reserved key word that the compiler knows well. return returns a value and ends the current function's run moving back up the stack to the function that invoked it (if any). In your code above it returns void as you have not supplied anything to return.

It's a standard problem due to how the computer stores floating point values. Search here for "floating point problem" and you'll find tons of information.

In short – a float/double can't store 0.1 precisely. It will always be a little off.

You can try using the decimal type which stores numbers in decimal notation. Thus 0.1 will be representable precisely.

You wanted to know the reason:

Float/double are stored as binary fractions, not decimal fractions. To illustrate:

12.34 in decimal notation (what we use) means

1 * 101 + 2 * 100 + 3 * 10-1 + 4 * 10-2

The computer stores floating point numbers in the same way, except it uses base 2: 10.01 means

1 * 21 + 0 * 20 + 0 * 2-1 + 1 * 2-2

Now, you probably know that there are some numbers that cannot be represented fully with our decimal notation. For example, 1/3 in decimal notation is 0.3333333…. The same thing happens in binary notation, except that the numbers that cannot be represented precisely are different. Among them is the number 1/10. In binary notation that is 0.000110011001100….

Since the binary notation cannot store it precisely, it is stored in a rounded-off way. Hence your problem.

Just change the version in Window-> Preferences-> Java -> Installed JREs. Check the installed JREs list. Then, Right-click on your project -> properties -> Java build path -> libraries. Change the "JRE System Library" to the version in "installed JREs".

The warning will be gone.

If you just want to get your HDFS back to normal state and don't worry much about the data, then

This will list the corrupt HDFS blocks:

hdfs fsck -list-corruptfileblocks

This will delete the corrupted HDFS blocks:

hdfs fsck / -delete

Note that, you might have to use sudo -u hdfs if you are not the sudo user (assuming "hdfs" is name of the sudo user)

Just Like TempTables, a local table variable is also created in TempDB. The scope of table variable is the batch, stored procedure and statement block in which it is declared. They can be passed as parameters between procedures. They are automatically dropped when you close that session on which you create them.

JSONP is JSON with padding. That is, you put a string at the beginning and a pair of parentheses around it. For example:

//JSON
{"name":"stackoverflow","id":5}
//JSONP
func({"name":"stackoverflow","id":5});

The result is that you can load the JSON as a script file. If you previously set up a function called func, then that function will be called with one argument, which is the JSON data, when the script file is done loading. This is usually used to allow for cross-site AJAX with JSON data. If you know that example.com is serving JSON files that look like the JSONP example given above, then you can use code like this to retrieve it, even if you are not on the example.com domain:

function func(json){
  alert(json.name);
}
var elm = document.createElement("script");
elm.setAttribute("type", "text/javascript");
elm.src = "http://example.com/jsonp";
document.body.appendChild(elm);

Try this, if your input is string 
For example 

string input= "13:01";
string[] arry = input.Split(':');                  
string timeinput = arry[0] + arry[1];
private string Convert24To12HourInEnglish(string timeinput)

 {

DateTime startTime = new DateTime(2018, 1, 1, int.Parse(timeinput.Substring(0, 2)), 
int.Parse(timeinput.Substring(2, 2)), 0); 
return startTime.ToString("hh:mm tt");

}
out put: 01:01

To read in an Unicode string and then send to HTML, I did this:

fileline.decode("utf-8").encode('ascii', 'xmlcharrefreplace')

Useful for python powered http servers.

Ubuntu

Try the following lines in Dockerfile:

RUN useradd -rm -d /home/ubuntu -s /bin/bash -g root -G sudo -u 1001 ubuntu
USER ubuntu
WORKDIR /home/ubuntu

useradd options (see: man useradd):

• -r, --system Create a system account. ^{see: Implications creating system accounts}
• -m, --create-home Create the user's home directory.
• -d, --home-dir HOME_DIR Home directory of the new account.
• -s, --shell SHELL Login shell of the new account.
• -g, --gid GROUP Name or ID of the primary group.
• -G, --groups GROUPS List of supplementary groups.
• -u, --uid UID Specify user ID. ^{see: Understanding how uid and gid work in Docker containers}
• -p, --password PASSWORD Encrypted password of the new account (e.g. ubuntu).

Setting default user's password

To set the user password, add -p "$(openssl passwd -1 ubuntu)" to useradd command.

Alternatively add the following lines to your Dockerfile:

SHELL ["/bin/bash", "-o", "pipefail", "-c"]
RUN echo 'ubuntu:ubuntu' | chpasswd

The first shell instruction is to make sure that -o pipefail option is enabled before RUN with a pipe in it. Read more: Hadolint: Linting your Dockerfile.

You can use vue-router.I have an example below:

url: www.example.com?name=john&lastName=doe

new Vue({
  el: "#app",
  data: {
    name: '',
    lastName: ''
  },
  beforeRouteEnter(to, from, next) {
      if(Object.keys(to.query).length !== 0) { //if the url has query (?query)
        next(vm => {
         vm.name = to.query.name
         vm.lastName = to.query.lastName
       })
    }
    next()
  }
})

Note: In beforeRouteEnter function we cannot access the component's properties like: this.propertyName.That's why i have pass the vm to next function.It is the recommented way to access the vue instance.Actually the vm it stands for vue instance

Guess you forgot to append the item to DOM.

Check it HERE.

Inside for-loops and iterator methods like each and map the next keyword in ruby will have the effect of jumping to the next iteration of the loop (same as continue in C).

However what it actually does is just to return from the current block. So you can use it with any method that takes a block - even if it has nothing to do with iteration.

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);

According to MDN, the way to retrieve an item from a NodeList is:

nodeItem = nodeList.item(index)

Thus:

var slides = document.getElementsByClassName("slide");
for (var i = 0; i < slides.length; i++) {
   Distribute(slides.item(i));
}

I haven't tried this myself (the normal for loop has always worked for me), but give it a shot.

check your cpanels space.remove unused file or error.log file & then try to login your application(This work for me);

You can use array_agg function for that:

SELECT "Movie",
array_to_string(array_agg(distinct "Actor"),',') AS Actor
FROM Table1
GROUP BY "Movie";

Thanks for your answers. I missed that my data is stored in a List<String> which is passed to the tested method. The mistake was that I put the string into the first element of the ArrayList. That's why I thought the String consists of just one single line, because the debugger showed me only one entry.

I've used a "breakout" pattern for this:

$(sentences).each(function() {
    var breakout;
    var s = this;
    alert(s);
    $(words).each(function(i) {
        if (s.indexOf(this) > -1)
        {
            alert('found ' + this);
            return breakout = false;
        }
    });
    return breakout;
});

This works nicely to any nesting depth. breakout is a simple flag. It will stay undefined unless and until you set it to false (as I do in my return statement as illustrated above). All you have to do is:

1. declare it in your outermost closure: var breakout;
2. add it to your return false statement(s): return breakout = false
3. return breakout in your outer closure(s).

Not too inelegant, right? ...works for me anyway.

Maybe you can integrate MuPdf in your application. Here is I've described how to do this: Integrate MuPDF Reader in an app

Make sure you also start the MySQL service in Xampp control panel. This might resolve this.

I disagree from @aprato answer, because the UIViewController rotation methods are declared in categories themselves, thus resulting in undefined behavior if you override then in another category. Its safer to override them in a UINavigationController (or UITabBarController) subclass

Also, this does not cover the scenario where you push / present / pop from a Landscape view into a portrait only VC or vice-versa. To solve this tough issue (never addressed by Apple), you should:

In iOS <= 4 and iOS >= 6:

UIViewController *vc = [[UIViewController alloc]init];
[self presentModalViewController:vc animated:NO];
[self dismissModalViewControllerAnimated:NO];
[vc release];

In iOS 5:

UIWindow *window = [[UIApplication sharedApplication] keyWindow];
UIView *view = [window.subviews objectAtIndex:0];
[view removeFromSuperview];
[window addSubview:view];

These will REALLY force UIKit to re-evaluate all your shouldAutorotate , supportedInterfaceOrientations, etc.

For completeness here is another method for emulating INTERSECT. Note that the IN (SELECT ...) form suggested in other answers is generally more efficient.

Generally for a table called mytable with a primary key called id:

SELECT id
FROM mytable AS a
INNER JOIN mytable AS b ON a.id = b.id
WHERE
(a.col1 = "someval")
AND
(b.col1 = "someotherval")

(Note that if you use SELECT * with this query you will get twice as many columns as are defined in mytable, this is because INNER JOIN generates a Cartesian product)

The INNER JOIN here generates every permutation of row-pairs from your table. That means every combination of rows is generated, in every possible order. The WHERE clause then filters the a side of the pair, then the b side. The result is that only rows which satisfy both conditions are returned, just like intersection two queries would do.

Convert.ToDouble(x) can also have a second parameter that indicates the CultureInfo and when you set it to System.Globalization.CultureInfo InvariantCulture the result will allways be the same.

In Visual Studio 2010 (until 2019 and possibly future versions) you can add the manifest file to your project.

Right click your project file on the Solution Explorer, select Add, then New item (or CTRL+SHIFT+A). There you can find Application Manifest File.

The file name is app.manifest.

Using scala:

import xml._
val xml = XML.loadString("<tag><nested>hello</nested></tag>")
val formatted = new PrettyPrinter(150, 2).format(xml)
println(formatted)

You can do this in Java too, if you depend on the scala-library.jar. It looks like this:

import scala.xml.*;

public class FormatXML {
    public static void main(String[] args) {
        String unformattedXml = "<tag><nested>hello</nested></tag>";
        PrettyPrinter pp = new PrettyPrinter(150, 3);
        String formatted = pp.format(XML.loadString(unformattedXml), TopScope$.MODULE$);
        System.out.println(formatted);
    }
}

The PrettyPrinter object is constructed with two ints, the first being max line length and the second being the indentation step.

This is how I managed to do what I was trying to do:

[Test]
public void TransferHandlesDisconnect()
{
    // ... set up config here
    var methodTester = new Mock<Transfer>(configInfo);
    methodTester.CallBase = true;
    methodTester
        .Setup(m => 
            m.GetFile(
                It.IsAny<IFileConnection>(), 
                It.IsAny<string>(), 
                It.IsAny<string>()
            ))
        .Throws<System.IO.IOException>();

    methodTester.Object.TransferFiles("foo1", "foo2");
    Assert.IsTrue(methodTester.Object.Status == TransferStatus.TransferInterrupted);
}

If there is a problem with this method, I would like to know; the other answers suggest I am doing this wrong, but this was exactly what I was trying to do.

You can use $.map() (or even the .map() function that operates on a jQuery object) to get an array of checked values. The unary (+) operator will cast the string to a number

var arr = $.map($('input:checkbox:checked'), function(e,i) {
    return +e.value;
});

console.log(arr);

Here's an example

This is entirely inspired by laurasia's answer above, but it refines the structure.

It also adds some checks:

• It will correctly return 0 when searching an empty file for the empty string. In laurasia's answer, this is an edge case that will return -1.
• It also pre-checks whether the goal string is larger than the buffer size, and raises an error if this is the case.

In practice, the goal string should be much smaller than the buffer for efficiency, and there are more efficient methods of searching if the size of the goal string is very close to the size of the buffer.

def fnd(fname, goal, start=0, bsize=4096):
    if bsize < len(goal):
        raise ValueError("The buffer size must be larger than the string being searched for.")
    with open(fname, 'rb') as f:
        if start > 0:
            f.seek(start)
        overlap = len(goal) - 1
        while True:
            buffer = f.read(bsize)
            pos = buffer.find(goal)
            if pos >= 0:
                return f.tell() - len(buffer) + pos
            if not buffer:
                return -1
            f.seek(f.tell() - overlap)

Did you install flask-sqlalchemy? It looks like you have SQLAlchemy installed but not the Flask extension. Try pip install Flask-SQLAlchemy in your project's virtualenv to install it from PyPI.

For Mapping Composite primary key using Entity framework we can use two approaches.

1) By Overriding the OnModelCreating() Method

For ex: I have the model class named VehicleFeature as shown below.

public class VehicleFeature
{
    public int VehicleId { get; set; }
    public int FeatureId{get;set;}
    public Vehicle Vehicle{get;set;}
    public Feature Feature{get;set;}
}

The Code in my DBContext would be like ,

public class VegaDbContext : DbContext
{
    public DbSet<Make> Makes{get;set;}

    public DbSet<Feature> Features{get;set;}
    public VegaDbContext(DbContextOptions<VegaDbContext> options):base(options)        
    {           

    }
    // we override the OnModelCreating method here.
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<VehicleFeature>().HasKey(vf=> new {vf.VehicleId, vf.FeatureId});
    }
}

2) By Data Annotations.

public class VehicleFeature
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]  
    [Key]
    public int VehicleId { get; set; }
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]   
    [Key]
    public int FeatureId{get;set;}
    public Vehicle Vehicle{get;set;}
    public Feature Feature{get;set;}
}

Hope this help somebody.

In list comprehension the loop variable i becomes global. After the iteration in the for loop it is a reference to the last element in your list.

If you want all matches then assign the list to a variable:

filtered =  [ i for i in my_list if i=='two']

If you want only the first match you could use a function generator

try:
     m = next( i for i in my_list if i=='two' )
except StopIteration:
     m = None

You are probably connecting fine but don't have sufficient privileges to run show dbs.

You don't need to run the db.auth if you pass the auth in the command line:

mongo somewhere.mongolayer.com:10011/my_database -u username -p password

Once you connect are you able to see collections?

> show collections

If so all is well and you just don't have admin privileges to the database and can't run the show dbs

#define NAME(x) printf("Hello " #x);
main(){
    NAME(Ian)
}
//will print: Hello Ian

There is an Oracle article I found regarding Java 9 module system

By default, a type in a module is not accessible to other modules unless it’s a public type and you export its package. You expose only the packages you want to expose. With Java 9, this also applies to reflection.

As pointed out in https://stackoverflow.com/a/50251958/134894, the differences between the AccessibleObject#setAccessible for JDK8 and JDK9 are instructive. Specifically, JDK9 added

This method may be used by a caller in class C to enable access to a member of declaring class D if any of the following hold:

• C and D are in the same module.
• The member is public and D is public in a package that the module containing D exports to at least the module containing C.
• The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D.
• D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

which highlights the significance of modules and their exports (in Java 9)

In addition, if you want to override all instances and not just that one special instance, this one might help.

function MyClass() {}

MyClass.prototype.myMethod = function() {
  alert( "doing original");
};
MyClass.prototype.myMethod_original = MyClass.prototype.myMethod;
MyClass.prototype.myMethod = function() {
  MyClass.prototype.myMethod_original.call( this );
  alert( "doing override");
};

myObj = new MyClass();
myObj.myMethod();

result:

doing original
doing override

Explaining the practical use for a closure in JavaScript

When we create a function inside another function, we are creating a closure. Closures are powerful because they are capable of reading and manipulating the data of its outer functions. Whenever a function is invoked, a new scope is created for that call. The local variable declared inside the function belong to that scope and they can only be accessed from that function. When the function has finished the execution, the scope is usually destroyed.

A simple example of such function is this:

function buildName(name) {
    const greeting = "Hello, " + name;
    return greeting;
}

In above example, the function buildName() declares a local variable greeting and returns it. Every function call creates a new scope with a new local variable. After the function is done executing, we have no way to refer to that scope again, so it’s garbage collected.

But how about when we have a link to that scope?

Let’s look at the next function:

function buildName(name) {
    const greeting = "Hello, " + name + " Welcome ";
    const sayName = function() {
        console.log(greeting);
    };
    return sayName;
}

const sayMyName = buildName("Mandeep");
sayMyName();  // Hello, Mandeep Welcome

The function sayName() from this example is a closure. The sayName() function has its own local scope (with variable welcome) and has also access to the outer (enclosing) function’s scope. In this case, the variable greeting from buildName().

After the execution of buildName is done, the scope is not destroyed in this case. The sayMyName() function still has access to it, so it won’t be garbage collected. However, there is no other way of accessing data from the outer scope except the closure. The closure serves as the gateway between the global context and the outer scope.

Great answer, "mu is too short". I was seeking the exact same thing, and after reading your post I found a solution that fitted my problem.

I was having two elements of the exact same size and wanted to stack them. As each have same size, what I could do was to make

position: absolute;
top: 0px;
left: 0px;

on only the last element. This way the first element is inserted correctly, "pushing" the parents height, and the second element is placed on top.

Hopes this helps other people trying to stacking 2+ elements with same (unknown) height.

From v1.10.2 onwards, you can also use ..

dt <- data.table(a=1:2, b=2:3, c=3:4)

keep_cols = c("a", "c")

dt[, ..keep_cols]

You can try using:

select trunc(sysdate - to_date('2009-10-01', 'yyyy-mm-dd')) as days from dual

Complate Angular Way ( Set/Get value by Id ):

       @ViewChild('userNameId') userNameId: ElementRef;

      ngAfterViewInit(){
         console.log(this.userNameId.nativeElement.value );
       }

      setValue(){
        this.userNameId.nativeElement.value = "Sample user Name";

Importing large sql file to MySql via command line

1. first download file .
2. paste file on home.
3. use following command in your terminals(CMD)
4. Syntax: mysql -u username -p databsename < file.sql

Example: mysql -u root -p aanew < aanew.sql

You will eventually be able to use

background-image: attr(data-image-src url);

but that is not implemented anywhere yet to my knowledge. In the above, url is an optional "type-or-unit" parameter to attr(). See https://drafts.csswg.org/css-values/#attr-notation.

The above solutions work if you are compressing all white space in the XML document. Other quick options are JDOM (using Format.getCompactFormat()) and dom4j (using OutputFormat.createCompactFormat()) when outputting the XML document.

However, I had a unique requirement to preserve the white space contained within the element's text value and these solutions did not work as I needed. All I needed was to remove the 'pretty-print' formatting added to the XML document.

The solution that I came up with can be explained in the following 3-step/regex process ... for the sake of understanding the algorithm for the solution.

String regex, updatedXml;

// 1. remove all white space preceding a begin element tag:
regex = "[\\n\\s]+(\\<[^/])";
updatedXml = originalXmlStr.replaceAll( regex, "$1" );

// 2. remove all white space following an end element tag:
regex = "(\\</[a-zA-Z0-9-_\\.:]+\\>)[\\s]+";
updatedXml = updatedXml.replaceAll( regex, "$1" );

// 3. remove all white space following an empty element tag
// (<some-element xmlns:attr1="some-value".... />):
regex = "(/\\>)[\\s]+";
updatedXml = updatedXml.replaceAll( regex, "$1" );

NOTE: The pseudo-code is in Java ... the '$1' is the replacement string which is the 1st capture group.

This will simply remove the white space used when adding the 'pretty-print' format to an XML document, yet preserve all other white space when it is part of the element text value.

SELECT pg_size_pretty(pg_database_size('name of database'));

Will give you the total size of a particular database however I don't think you can do all databases within a server.

However you could do this...

DO
$$
DECLARE
r   RECORD;
db_size TEXT;
BEGIN
FOR r in
SELECT datname FROM pg_database
WHERE datistemplate = false
LOOP
db_size:= (SELECT pg_size_pretty(pg_database_size(r.datname)));

RAISE NOTICE 'Database:% , Size:%', r.datname , db_size;

END LOOP;
END;
$$

This usually means that there was a network error, such as a TCP timeout. I would start by placing a sniffer (wireshark) on the connection to see if you can see any problems. If there is a TCP error, you should be able to see it. Also, you can check your router logs, if this is applicable. If wireless is involved anywhere, that is another source for these kind of errors.

As of C++17, you can use Structured Bindings:

#include <iostream>
#include <tuple>

int main () 
{
    auto [hello, world] = std::make_tuple("Hello ", "world!");
    std::cout << hello << world << std::endl;
    return 0;
}

Demo

You need to do the following

git fetch -p

This will update the local database of remote branches.

Using 'minifyEnabled' instead of 'runProguard' works properly.

Previous code:

buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

Current code:

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

Hope this helps.

The function argument to setTimeout is closing over the loop variable. The loop finishes before the first timeout and displays the current value of i, which is 3.

Because JavaScript variables only have function scope, the solution is to pass the loop variable to a function that sets the timeout. You can declare and call such a function like this:

for (var i = 1; i <= 2; i++) {
    (function (x) {
        setTimeout(function () { alert(x); }, 100);
    })(i);
}

You could try Jsonium tool http://jsonium.org- nice free tool specialized on requests with JSON in bodies and responses

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

Try running the following query:

repair table <table_name>;

I had the same issue and it solved me the problem.

Ideally, I would use a construct like this instead:

for (std::vector<your_type>::const_iterator i = things.begin(); i != things.end(); ++i)
{
  // if you ever need the distance, you may call std::distance
  // it won't cause any overhead because the compiler will likely optimize the call
  size_t distance = std::distance(things.begin(), i);
}

This a has the neat advantage that your code suddenly becomes container agnostic.

And regarding your problem, if some library you use requires you to use int where an unsigned int would better fit, their API is messy. Anyway, if you are sure that those int are always positive, you may just do:

int int_distance = static_cast<int>(distance);

Which will specify clearly your intent to the compiler: it won't bug you with warnings anymore.

I got this error when trying to add the Service reference for the first Silverlight enabled WCF in the same solution. I just build the .Web project and it started working..

I think a much better method is to do this in the Program.cs file where you usually have Application.Run(form1), in this way you get a cleaner approach, Login form does not need to be coupled to Main form, you simply show the login and if it returns true you display the main form otherwise the error.

You can return a number by using this trick:
not recommended

[a] + b - 0

Example :

let output = [5] + 6 - 0;
console.log(output); // 56
console.log(typeof output); // number

You are really talking about serialization, which can take many forms. Since you want small and binary, protocol buffers may be a viable option - giving version tolerance and portability as well. Unlike BinaryFormatter, the protocol buffers wire format doesn't include all the type metadata; just very terse markers to identify data.

In .NET there are a few implementations; in particular

• protobuf-net
• dotnet-protobufs

I'd humbly argue that protobuf-net (which I wrote) allows more .NET-idiomatic usage with typical C# classes ("regular" protocol-buffers tends to demand code-generation); for example:

[ProtoContract]
public class Person {
   [ProtoMember(1)]
   public int Id {get;set;}
   [ProtoMember(2)]
   public string Name {get;set;}
}
....
Person person = new Person { Id = 123, Name = "abc" };
Serializer.Serialize(destStream, person);
...
Person anotherPerson = Serializer.Deserialize<Person>(sourceStream);

It is worth noting that what you're doing isn't rounding, it's casting. Casting using (int) x truncates the decimal value of x. As in your example, if x = 3.9995, the .9995 gets truncated and x = 3.

As proposed by many others, one solution is to add 0.5 to x, and then cast.

Another simple recipe seems to work well for me:

git clone --bare $URL .git
git config core.bare false

My main use case for checking out to a directory with existing files is to control my Unix dotfiles with Git. On a new account, the home directory will already have some files in it, possibly even the ones I want to get from Git.

Microsoft Support says "Maximum URL length is 2,083 characters in Internet Explorer".

IE has problems with URLs longer than that. Firefox seems to work fine with >4k chars.

Here is the example of a web.config that solve the issue for me. Pay attention on the <binding name="TransportSecurity" messageEncoding="Text" textEncoding="utf-8">

Thread.Sleep(50);

The thread will not be scheduled for execution by the operating system for the amount of time specified. This method changes the state of the thread to include WaitSleepJoin.

This method does not perform standard COM and SendMessage pumping. If you need to sleep on a thread that has STAThreadAttribute, but you want to perform standard COM and SendMessage pumping, consider using one of the overloads of the Join method that specifies a timeout interval.

Thread.Join

This comment syntax should work for you:

Let us consider table name as tblperson and column name as city. I want to retrieve the most repeated city from the city column:

 select city,count(*) as nor from tblperson
        group by city
          having count(*) =(select max(nor) from 
            (select city,count(*) as nor from tblperson group by city) tblperson)

Here nor is an alias name.

That could be a solution;

Array.Resize(ref array, newsize);
array[newsize - 1] = "newvalue"

But for dynamic sized array I would prefer list too.

I'm also about to ask the same question. But from what I've learned from codeacademy.com below code is enough to display the output or text?

print("hello world")  

Warning: Checking for 'IS_AUTHENTICATED_FULLY' alone will return false if the user has logged in using "Remember me" functionality.

According to Symfony 2 documentation, there are 3 possibilities:

IS_AUTHENTICATED_ANONYMOUSLY - automatically assigned to a user who is in a firewall protected part of the site but who has not actually logged in. This is only possible if anonymous access has been allowed.

IS_AUTHENTICATED_REMEMBERED - automatically assigned to a user who was authenticated via a remember me cookie.

IS_AUTHENTICATED_FULLY - automatically assigned to a user that has provided their login details during the current session.

Those roles represent three levels of authentication:

If you have the IS_AUTHENTICATED_REMEMBERED role, then you also have the IS_AUTHENTICATED_ANONYMOUSLY role. If you have the IS_AUTHENTICATED_FULLY role, then you also have the other two roles. In other words, these roles represent three levels of increasing "strength" of authentication.

I ran into an issue where users of our system that had used "Remember Me" functionality were being treated as if they had not logged in at all on pages that only checked for 'IS_AUTHENTICATED_FULLY'.

The answer then is to require them to re-login if they are not authenticated fully, or to check for the remembered role:

$securityContext = $this->container->get('security.authorization_checker');
if ($securityContext->isGranted('IS_AUTHENTICATED_REMEMBERED')) {
    // authenticated REMEMBERED, FULLY will imply REMEMBERED (NON anonymous)
}

Hopefully, this will save someone out there from making the same mistake I made. I used this very post as a reference when looking up how to check if someone was logged in or not on Symfony 2.

For reference purpose, for anyone searching how to change the path via code, I am quoting a useful post by a Delphi programmer from this web page: http://www.tek-tips.com/viewthread.cfm?qid=686382

TonHu (Programmer) 22 Oct 03 17:57 I found where I read the original posting, it's here: http://news.jrsoftware.org/news/innosetup.isx/msg02129....

The excerpt of what you would need is this:

You must specify the string "Environment" in LParam. In Delphi you'd do it this way:

 SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, Integer(PChar('Environment')));

It was suggested by Jordan Russell, http://www.jrsoftware.org, the author of (a.o.) InnoSetup, ("Inno Setup is a free installer for Windows programs. First introduced in 1997, Inno Setup today rivals and even surpasses many commercial installers in feature set and stability.") (I just would like more people to use InnoSetup )

The simplest way is :

SHOW OPEN TABLES WHERE In_use > 0

You get the locked tables only of the current database.

Update 2016: seems to be working again.

Update August 2014: No longer works as of recent Chrome versions.

Yeah, the new state of affairs sucks. Fortunately it's not so hard as the other answers imply.

1. Browse in Chrome to chrome://extensions
2. Drag the .user.js file into that page.

Voila. You can also drag files from the downloads footer bar to the extensions tab.

Chrome will automatically create a manifest.json file in the extensions directory that Brock documented.

<3 Freedom.

I guess I found a simpler solution

temp1 = pd.melt(df1, id_vars=["location"], var_name='Date', value_name='Value')
temp2 = pd.melt(df1, id_vars=["name"], var_name='Date', value_name='Value')

Concat whole temp1 with temp2's column name

temp1['new_column'] = temp2['name']

You now have what you asked for.

This might have been asked before. See Can I add jars to maven 2 build classpath without installing them?

In a nutshell: include your jar as dependency with system scope. This requires specifying the absolute path to the jar.

When tree width is very large and depth is low use DFS as recursion stack will not overflow.Use BFS when width is low and depth is very large to traverse the tree.

Great piece of code, thanks for sharing!

I ended up using reflection to get the actual DataMemberName to throw back to a client on an error (I'm using bulk save in a WCF service). Hopefully someone else will find how I did it useful.

static string GetDataMemberName(string colName, object t) {_x000D_
  foreach(PropertyInfo propertyInfo in t.GetType().GetProperties()) {_x000D_
    if (propertyInfo.CanRead) {_x000D_
      if (propertyInfo.Name == colName) {_x000D_
        var attributes = propertyInfo.GetCustomAttributes(typeof(DataMemberAttribute), false).FirstOrDefault() as DataMemberAttribute;_x000D_
        if (attributes != null && !string.IsNullOrEmpty(attributes.Name))_x000D_
          return attributes.Name;_x000D_
        return colName;_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
  return colName;_x000D_
}

As others have said, it will only work when T is constrained to be a reference type. Without any constraints, you can compare with null, but only null - and that comparison will always be false for non-nullable value types.

Instead of calling Equals, it's better to use an IComparer<T> - and if you have no more information, EqualityComparer<T>.Default is a good choice:

public bool Compare<T>(T x, T y)
{
    return EqualityComparer<T>.Default.Equals(x, y);
}

Aside from anything else, this avoids boxing/casting.

As @Haza pointed out the times symbol can be used. Twitter Bootstrap maps this to a close icon for dismissing content like modals and alerts.

<button class="close">&times;</button>

I'm surprised to see all answers stating the use of alt attribute in a tag is not valid. This is absolutely wrong.

Html does not block you using any attributes:

<a your-custom-attribute="value">Any attribute can be used</a>

If you ask if it is semantically correct to use alt attribute in a then I will say:

NO. It is used to set image description <img alt="image description" />.

It is a matter of what you'd do with the attributes. Here's an example:

a::after {_x000D_
  content: attr(color); /* attr can be used as content */_x000D_
  display: block;_x000D_
  color: white;_x000D_
  background-color: blue;_x000D_
  background-color: attr(color); /* This won't work */_x000D_
  display: none;_x000D_
}_x000D_
a:hover::after {_x000D_
  display: block;_x000D_
}_x000D_
[hidden] {_x000D_
  display: none;_x000D_
}

<a href="#" color="red">Hover me!</a>_x000D_
<a href="#" color="red" hidden>In some cases, it can be used to hide it!</a>

Again, if you ask if it is semantically correct to use custom attribute then I will say:

No. Use data-* attributes for its semantic use.

Oops, question was asked in 2013.

Always have handy the un-minified CSS for bootstrap so you can see what styles they have on their components, then create a CSS file AFTER it, if you don't use LESS and over-write their mixins or whatever

This is the default modal css for 768px and up:

@media (min-width: 768px) {
  .modal-dialog {
    width: 600px;
    margin: 30px auto;
  }
  ...
}

They have a class modal-lg for larger widths

@media (min-width: 992px) {
  .modal-lg {
    width: 900px;
  }
}

If you need something twice the 600px size, and something fluid, do something like this in your CSS after the Bootstrap css and assign that class to the modal-dialog.

@media (min-width: 768px) {
  .modal-xl {
    width: 90%;
   max-width:1200px;
  }
}

HTML

<div class="modal-dialog modal-xl">

Base64 overhead is 33%.

BaseXML for XML1.0 overhead is only 20%. But it's not a standard and only have a C implementation yet. Check it out if you're concerned with data size. Note that however browsers tends to implement compression so that it is less needed.

I developed it after the discussion in this thread: Encoding binary data within XML : alternatives to base64.

Important Note: As of mid-2018, the process to get twitter API tokens became a lot more bureaucratic. It has taken me over one working week to be provided a set of API tokens, and this is for an open source project for you guys and girls with over 1.2 million installations on Packagist and 1.6k stars on Github, which theoretically should be higher priority.

If you are tasked with working with the twitter API for your work, you must take this potentially extremely long wait-time into account. Also consider other social media avenues like Facebook or Instagram and provide these options, as the process for retrieving their tokens is instant.

So you want to use the Twitter v1.1 API?

Note: the files for these are on GitHub.

Version 1.0 will soon be deprecated and unauthorised requests won't be allowed. So, here's a post to help you do just that, along with a PHP class to make your life easier.

1. Create a developer account: Set yourself up a developer account on Twitter

You need to visit the official Twitter developer site and register for a developer account. This is a free and necessary step to make requests for the v1.1 API.

2. Create an application: Create an application on the Twitter developer site

What? You thought you could make unauthenticated requests? Not with Twitter's v1.1 API. You need to visit http://dev.twitter.com/apps and click the "Create Application" button.

On this page, fill in whatever details you want. For me, it didn't matter, because I just wanted to make a load of block requests to get rid of spam followers. The point is you are going to get yourself a set of unique keys to use for your application.

So, the point of creating an application is to give yourself (and Twitter) a set of keys. These are:

• The consumer key
• The consumer secret
• The access token
• The access token secret

There's a little bit of information here on what these tokens for.

3. Create access tokens: You'll need these to make successful requests

OAuth requests a few tokens. So you need to have them generated for you.

Click "create my access token" at the bottom. Then once you scroll to the bottom again, you'll have some newly generated keys. You need to grab the four previously labelled keys from this page for your API calls, so make a note of them somewhere.

4. Change access level: You don't want read-only, do you?

If you want to make any decent use of this API, you'll need to change your settings to Read & Write if you're doing anything other than standard data retrieval using GET requests.

Choose the "Settings" tab near the top of the page.

Give your application read / write access, and hit "Update" at the bottom.

You can read more about the applications permission model that Twitter uses here.

5. Write code to access the API: I've done most of it for you

I combined the code above, with some modifications and changes, into a PHP class so it's really simple to make the requests you require.

This uses OAuth and the Twitter v1.1 API, and the class I've created which you can find below.

require_once('TwitterAPIExchange.php');

/** Set access tokens here - see: https://dev.twitter.com/apps/ **/
$settings = array(
    'oauth_access_token' => "YOUR_OAUTH_ACCESS_TOKEN",
    'oauth_access_token_secret' => "YOUR_OAUTH_ACCESS_TOKEN_SECRET",
    'consumer_key' => "YOUR_CONSUMER_KEY",
    'consumer_secret' => "YOUR_CONSUMER_SECRET"
);

Make sure you put the keys you got from your application above in their respective spaces.

Next you need to choose a URL you want to make a request to. Twitter has their API documentation to help you choose which URL and also the request type (POST or GET).

/** URL for REST request, see: https://dev.twitter.com/docs/api/1.1/ **/
$url = 'https://api.twitter.com/1.1/blocks/create.json';
$requestMethod = 'POST';

In the documentation, each URL states what you can pass to it. If we're using the "blocks" URL like the one above, I can pass the following POST parameters:

/** POST fields required by the URL above. See relevant docs as above **/
$postfields = array(
    'screen_name' => 'usernameToBlock', 
    'skip_status' => '1'
);

Now that you've set up what you want to do with the API, it's time to make the actual request.

/** Perform the request and echo the response **/
$twitter = new TwitterAPIExchange($settings);
echo $twitter->buildOauth($url, $requestMethod)
             ->setPostfields($postfields)
             ->performRequest();

And for a POST request, that's it!

For a GET request, it's a little different. Here's an example:

/** Note: Set the GET field BEFORE calling buildOauth(); **/
$url = 'https://api.twitter.com/1.1/followers/ids.json';
$getfield = '?username=J7mbo';
$requestMethod = 'GET';
$twitter = new TwitterAPIExchange($settings);
echo $twitter->setGetfield($getfield)
             ->buildOauth($url, $requestMethod)
             ->performRequest();     

Final code example: For a simple GET request for a list of my followers.

$url = 'https://api.twitter.com/1.1/followers/list.json';
$getfield = '?username=J7mbo&skip_status=1';
$requestMethod = 'GET';
$twitter = new TwitterAPIExchange($settings);
echo $twitter->setGetfield($getfield)
             ->buildOauth($url, $requestMethod)
             ->performRequest();  

I've put these files on GitHub with credit to @lackovic10 and @rivers! I hope someone finds it useful; I know I did (I used it for bulk blocking in a loop).

Also, for those on Windows who are having problems with SSL certificates, look at this post. This library uses cURL under the hood so you need to make sure you have your cURL certs set up probably. Google is also your friend.

Accepted answer in Xamarin would be (use sizeWithAttributes and UITextAttributeFont):

        UIStringAttributes attributes = new UIStringAttributes
        { 
            Font = UIFont.SystemFontOfSize(17) 
        }; 
        var size = text.GetSizeUsingAttributes(attributes);

Very Simple:

Adding JS/CSS in the Front End:

function enqueue_related_pages_scripts_and_styles(){
        wp_enqueue_style('related-styles', plugins_url('/css/bootstrap.min.css', __FILE__));
        wp_enqueue_script('releated-script', plugins_url( '/js/custom.js' , __FILE__ ), array('jquery','jquery-ui-droppable','jquery-ui-draggable', 'jquery-ui-sortable'));
    }
add_action('wp_enqueue_scripts','enqueue_related_pages_scripts_and_styles');

Adding JS/CSS in WP Admin Area:

function enqueue_related_pages_scripts_and_styles(){
        wp_enqueue_style('related-pages-admin-styles',  get_stylesheet_directory_uri() . '/admin-related-pages-styles.css');
        wp_enqueue_script('releated-pages-admin-script', plugins_url( '/js/custom.js' , __FILE__ ), array('jquery','jquery-ui-droppable','jquery-ui-draggable', 'jquery-ui-sortable'));
    }
add_action('admin_enqueue_scripts','enqueue_related_pages_scripts_and_styles');

You can use momentjs duration object

Example:

const diff = moment.duration(Date.now() - new Date(2010, 1, 1))
console.log(`${diff.years()} years ${diff.months()} months ${diff.days()} days ${diff.hours()} hours ${diff.minutes()} minutes and ${diff.seconds()} seconds`)

Code To Get Today's date in any specific Format

You can define the desired format in SimpleDateFormat instance to get the date in that specific formate

 DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
        Calendar cal = Calendar.getInstance();
        Date date = cal.getTime();
        String todaysdate = dateFormat.format(date);
         System.out.println("Today's date : " + todaysdate);

Follow below links to see the valid date format combination.

https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

CODE : To get x days ahead or Previous from Today's date, To get the past date or Future date.

For Example :

Today date : 11/27/2018

xdayFromTodaysDate = 2 to get date as 11/29/2018

xdayFromTodaysDate = -2 to get date as 11/25/2018

  public String getAniversaryDate(int xdayFromTodaysDate ){

        DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
        Calendar cal = Calendar.getInstance();
        Date date = cal.getTime();
        cal.setTime(date);
        cal.add(Calendar.DAY_OF_MONTH,xdayFromTodaysDate);
        date = cal.getTime();
        String aniversaryDate = dateFormat.format(date);
        LOGGER.info("Today's date : " + todaysdate);
          return aniversaryDate;

    }

CODE : To get x days ahead or Previous from a Given date

  public String getAniversaryDate(String givendate, int xdayFromTodaysDate ){


        Calendar cal = Calendar.getInstance();
        DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
        try {
            Date date = dateFormat.parse(givendate);
            cal.setTime(date);
            cal.add(Calendar.DAY_OF_MONTH,xdayFromTodaysDate);
            date = cal.getTime();
            String aniversaryDate = dateFormat.format(date);
            LOGGER.info("aniversaryDate : " + aniversaryDate);
            return aniversaryDate;
        } catch (ParseException e) {
            e.printStackTrace();
            return null;
        }

    }

From the official install page -

To remove an existing Go installation from your system delete the go directory. This is usually /usr/local/go under Linux, macOS, and FreeBSD or c:\Go under Windows.

You should also remove the Go bin directory from your PATH environment variable. Under Linux and FreeBSD you should edit /etc/profile or $HOME/.profile. If you installed Go with the macOS package then you should remove the /etc/paths.d/go file. Windows users should read the section about setting environment variables under Windows.

After reading the accepted answer's comments, I tried the robocopy command, which worked for me (using the standard command prompt from Windows 7 64 bits SP 1):

robocopy source_dir dest_dir /s /e

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

I think the best and cleanest solution you can imagine is this:

@Component( {
  selector: 'app-my-component',
  template: `<p>{{ myData?.anyfield }}</p>`,
  styles: [ '' ]
} )
export class MyComponent implements OnInit {
  private myData;

  constructor( private myService: MyService ) { }

  ngOnInit( ) {
    /* 
      async .. await 
      clears the ExpressionChangedAfterItHasBeenCheckedError exception.
    */
    this.myService.myObservable.subscribe(
      async (data) => { this.myData = await data }
    );
  }
}

Tested with Angular 5.2.9

You can call sortable on a <tbody> instead of on the individual rows.

    <tbody>
        <tr> 
            <td>1</td>
            <td>2</td>

            <td>5</td>
            <td>6</td>
        </tr>  
    </tbody>

Translate composed UInt32 color Value to CSS in .NET

I know the question applies to 3 input values (red green blue). But there may be the situation where you already have a composed 32bit Value. It looks like you want to send the data to some HTML CSS renderer (because of the #HEX format). Actually CSS wants you to print 6 or at least 3 zero filled hex digits here. so #{0:X06} or #{0:X03} would be required. Due to some strange behaviour, this always prints 8 digits instead of 6.

Solve this by:

String.Format("#{0:X02}{1:X02}{2:X02}", (Value & 0x00FF0000) >> 16, (Value & 0x0000FF00) >> 8, (Value & 0x000000FF) >> 0)

What did the trick for me was to re-install NuGet Package Manager by using the link below:

VS 2013: https://github.com/NuGet/Home/releases/download/2.8.7/NuGet.Tools.vsix

VS 2015: https://github.com/NuGet/Home/releases/download/3.1.1/NuGet.Tools.vsix

$(".clscss-row").each(function () {
if ($(this).find(".po-checkbox").not(":checked")) {
               // enter your code here
            } });

You can kill by job number. When you put a task in the background you'll see something like:

$ ./script &
[1] 35341

That [1] is the job number and can be referenced like:

$ kill %1
$ kill %%  # Most recent background job

To see a list of job numbers use the jobs command. More from man bash:

There are a number of ways to refer to a job in the shell. The character % introduces a job name. Job number n may be referred to as %n. A job may also be referred to using a prefix of the name used to start it, or using a substring that appears in its command line. For example, %ce refers to a stopped ce job. If a prefix matches more than one job, bash reports an error. Using %?ce, on the other hand, refers to any job containing the string ce in its command line. If the substring matches more than one job, bash reports an error. The symbols %% and %+ refer to the shell's notion of the current job, which is the last job stopped while it was in the foreground or started in the background. The previous job may be referenced using %-. In output pertaining to jobs (e.g., the output of the jobs command), the current job is always flagged with a +, and the previous job with a -. A single % (with no accompanying job specification) also refers to the current job.

for( ; it != res.end();)
{
    it = res.erase(it);
}

or, more general:

for( ; it != res.end();)
{
    if (smth)
        it = res.erase(it);
    else
        ++it;
}

If you want it one time & let system handle the rest (not dynamic) then do like this in your manifest file:

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name_full" > //This is my custom title name on activity. <- The question is about this one.
            <intent-filter android:label="@string/app_launcher_name" > //This is my custom Icon title name (launcher name that you see in android apps/homescreen)
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

Just found this, it works for me and I personally find it easier to read.

This will set the actual index just like gnarf's answer number 3 option.

// sets selected index of a select box the actual index of 0 
$("select#elem").attr('selectedIndex', 0);

This didn't used to work but does now... see bug: http://dev.jquery.com/ticket/1474

Addendum

As recommended in the comments use :

$("select#elem").prop('selectedIndex', 0);

Complete instruction is as follow:

1. Extract Private Key from PFX

openssl pkcs12 -in myfile.pfx -nocerts -out private-key.pem -nodes

2. Extract Certificate from PFX

openssl pkcs12 -in myfile.pfx -nokeys -out certificate.pem

3. install certificate

yum install -y ca-certificates,

cp your-cert.pem /etc/pki/ca-trust/source/anchors/your-cert.pem ,

update-ca-trust ,

update-ca-trust force-enable

Hope to be useful

No, Java doesn't support user-defined operator overloading. The only aspect of Java which comes close to "custom" operator overloading is the handling of + for strings, which either results in compile-time concatenation of constants or execution-time concatenation using StringBuilder/StringBuffer. You can't define your own operators which act in the same way though.

For a Java-like (and JVM-based) language which does support operator overloading, you could look at Kotlin or Groovy. Alternatively, you might find luck with a Java compiler plugin solution.

First of all you need to be sure that all attributes of that comes from the service are named the same in your class. Then you can parse the object and after that assign it to your new variable, something like this:

const parsedJSON = JSON.parse(serverResponse);
const employeeObj: Employee = parsedJSON as Employee;

Try that!

For verbose > 0, fit method logs:

• loss: value of loss function for your training data
• acc: accuracy value for your training data.

Note: If regularization mechanisms are used, they are turned on to avoid overfitting.

if validation_data or validation_split arguments are not empty, fit method logs:

• val_loss: value of loss function for your validation data
• val_acc: accuracy value for your validation data

Note: Regularization mechanisms are turned off at testing time because we are using all the capabilities of the network.

For example, using verbose while training the model helps to detect overfitting which occurs if your acc keeps improving while your val_acc gets worse.

OR... to place 20 points, compute the centers of the icosahedronal faces. For 12 points, find the vertices of the icosahedron. For 30 points, the mid point of the edges of the icosahedron. you can do the same thing with the tetrahedron, cube, dodecahedron and octahedrons: one set of points is on the vertices, another on the center of the face and another on the center of the edges. They cannot be mixed, however.

A generic,simpler and a bit primitive approach to find tag, attribute and value

    Pattern pattern = Pattern.compile("<(\\w+)( +.+)*>((.*))</\\1>");
    System.out.println(pattern.matcher("<asd> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd TEST</asd>").find());
    System.out.println(pattern.matcher("<asd attr='3'> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd> <x>TEST<x>asd>").find());
    System.out.println("-------");
    Matcher matcher = pattern.matcher("<as x> TEST</as>");
    if (matcher.find()) {
        for (int i = 0; i <= matcher.groupCount(); i++) {
            System.out.println(i + ":" + matcher.group(i));
        }
    }

You can follow this pattern also

<form action="/action_page.php">
  E-mail: <input type="email" name="email" pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,}$">
  <input type="submit">
</form>

To export the output to file on a continuous basis (here every five seconds) and save to a CSV file with the Unix date as the filename:

while ($true) {
     [int]$date = get-date -Uformat %s
     $exportlocation = New-Item -type file -path "c:\$date.csv"
     Get-Counter -Counter "\Processor(_Total)\% Processor Time" | % {$_} | Out-File $exportlocation
     start-sleep -s 5
}

An answer has already been accepted, but in these situations, a more elegant solution in my opinion would be to use error handling.

    try {
        $user = User::where('mobile', Input::get('mobile'))->first();
    } catch (ErrorException $e) {
        // Do stuff here that you need to do if it doesn't exist.
        return View::make('some.view')->with('msg', $e->getMessage());
    }

SELECT @@servername will give you data as server/instanceName

To get only the instanceName you should run select @@ServiceName query .

Also experienced issues with Java the last 2 weeks no longer working in IE 11 under Windows 7 x64 (reverted to Chrome where it DID work)

I had to go through (ALL) the following steps in order to restore Java operation:

1. Try and install latest Java => Error was produced 'The installer cannot proceed with the current Internet Connection setting'

2. Hit 'Retry', and the installer started working

3. Java 8 update 40 was installed successfully, however Java still doesn't work in IE (after closing IE / reboot)

4. Removed older/outdated versions (either using the Oracle-Java tool or through Install/Uninstall programs). In my case, I was able to remove old version 7 update 71.

5. After another attempt to close IE completely and restarting Windows did not resolve the issue (as before, testing Java operation using the Oracle-Java online tool failed to work and even failed to produce the 'grey box' that is always shown (in spite of the fact that the Java-plugins are loaded and activated)

6. Finally restored IE settings through: Internet options -> Advanced -> Reset (Note: I tried that before 1 week earlier, but then this DID NOT yield a solution either)

7. Eureka, it works again !

Result is now as follows using the Oracle-Java online test tool, and any Java-applets now work again in IE11: "Gefeliciteerd! U beschikt over de juiste Java-versie. (Version 8 Update 40)."

SELECT COUNT(ID) FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For count


SELECT ID FROM tblA a
WHERE a.ID NOT IN (SELECT b.ID FROM tblB b)    --For results

I've found this issue to be prevalent in Entity Framework when we instantiate an Entity manually rather than through DBContext which will resolve all the Navigation Properties. If there are Foreign Key references (Navigation Properties) between tables and you use those references in your lambda (e.g. ProductDetail.Products.ID) then that "Products" context remains null if you manually created the Entity.

Here is some information about one more source of the JSESSIONID cookie:

I was just debugging some Java code that runs on a tomcat server. I was not calling request.getSession() explicitly anywhere in my code but I noticed that a JSESSIONID cookie was still being set.

I finally took a look at the generated Java code corresponding to a JSP in the work directory under Tomcat.

It appears that, whether you like it or not, if you invoke a JSP from a servlet, JSESSIONID will get created!

Added: I just found that by adding the following JSP directive:

<%@ page session="false" %>

you can disable the setting of JSESSIONID by a JSP.

I was facing some difficulties with an environment variable that is with custom name (not with container name /port convention for KAPACITOR_BASE_URL and KAPACITOR_ALERTS_ENDPOINT). If we give service name in this case it wouldn't resolve the ip as

KAPACITOR_BASE_URL:  http://kapacitor:9092

In above http://[**kapacitor**]:9092 would not resolve to http://172.20.0.2:9092

I resolved the static IPs issues using subnetting configurations.

You have to wrap \n or \r in "", not ''. When using single quotes escape sequences will not be interpreted (except \' and \\).

The manual states:

If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:

• \n linefeed (LF or 0x0A (10) in ASCII)

• \r carriage return (CR or 0x0D (13) in ASCII)\

• (...)

If you're just using a vanilla form (not a ModelForm), you can set a Field initial value ( https://docs.djangoproject.com/en/2.2/ref/forms/fields/#django.forms.Field.initial ) like

class MyForm(forms.Form):
    my_field = forms.BooleanField(initial=True)

If you're using a ModelForm, you can set a default value on the model field ( https://docs.djangoproject.com/en/2.2/ref/models/fields/#default ), which will apply to the resulting ModelForm, like

class MyModel(models.Model):
    my_field = models.BooleanField(default=True)

Finally, if you want to dynamically choose at runtime whether or not your field will be selected by default, you can use the initial parameter to the form when you initialize it:

form = MyForm(initial={'my_field':True})

I just figured it out! What I did was I created the batch file like I had it originally:

net use P: "\\server\foldername\foldername"

I then saved it to the desktop and right clicked the properties and checked run as administrator. I then copied the file to C:\Users\"TheUser"\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Where "TheUser" was the desired user I wanted to add it to.

A "Broken Pipe" error occurs when you try to write to a pipe that has been closed on the other end. Since the code you've shown doesn't involve any pipes directly, I suspect you're doing something outside of Python to redirect the standard output of the Python interpreter to somewhere else. This could happen if you're running a script like this:

python foo.py | someothercommand

The issue you have is that someothercommand is exiting without reading everything available on its standard input. This causes your write (via print) to fail at some point.

I was able to reproduce the error with the following command on a Linux system:

python -c 'for i in range(1000): print i' | less

If I close the less pager without scrolling through all of its input (1000 lines), Python exits with the same IOError you have reported.

stage.setOnCloseRequest(new EventHandler<WindowEvent>() {
    public void handle(WindowEvent we) {                        
        Platform.setImplicitExit(false);
        stage.close();
    }
});

It is equivalent to hide. So when you are going to open it next time, you just check if the stage object is exited or not. If it is exited, you just show() i.e. (stage.show()) call. Otherwise, you have to start the stage.

I had the same problem but previous solutions not work for me. The only solution works for me is the following URL.

https://enlightensoft.wordpress.com/2013/01/15/maven-error-reading-error-in-opening-zip-file/

[EDIT]

Here I explain more about it

Suppose you got an error like below

[ERROR] error: error reading C:\Users\user\.m2\repository\org\jdom\jdom\1.1\jdom-1.1.jar; error in opening zip file

Then you have to follow these steps.

1. First, delete the existing jar C:\Users\user\.m2\repository\org\jdom\jdom\1.1\jdom-1.1.jar
2. Then you have to manually download relevant jar from Maven central repository. You can download from this link here
3. After that, you have to copy that downloaded jar into the previous directory.C:\Users\user\.m2\repository\org\jdom\jdom\1.1\

Then you can build your project using mvn clean install

hope this will help somebody.

image.ScaleToFit(500f,30f);

this method keeps the aspect ratio of the image

A PIL only solution for creating a bi-level (black and white) image with a custom threshold:

from PIL import Image
img = Image.open('mB96s.png')
thresh = 200
fn = lambda x : 255 if x > thresh else 0
r = img.convert('L').point(fn, mode='1')
r.save('foo.png')

With just

r = img.convert('1')
r.save('foo.png')

you get a dithered image.

From left to right the input image, the black and white conversion result and the dithered result:

You can click on the images to view the unscaled versions.

Remove from app gradle this code

android{
    defaultConfig.applicationId="com.storiebox"
}

On mac and sublime text 3 , which version is 3103, the content should be

{
    "shell_cmd": "open -a 'Google Chrome' '$file'"
}

You need to make sure that the first numeral to the right of the decimal point is always displayed. In custom format strings, # means display the number if it exists, and 0 means always display something, with 0 as the placeholder.

So in your case you will need something like:

=Format(Fields!CUL1.Value, "#,##0.##")

This saying: display 2 DP if they exist, for the non-zero part always display the lowest part, and use , as the grouping separator.

This is how it looks on your data (I've added a large value as well for reference):

If you're not interested in separating thousands, millions, etc, just use #0.## as Paul-Jan suggested.

The standard docs for Custom Numeric Format Strings are your best reference here.

Yes, definietly requests is great package to use in something related to HTTP requests. but we need to be careful with the encoding type of the incoming data as well below is an example which explains the difference

from requests import get

# case when the response is byte array
url = 'some_image_url'

response = get(url)
with open('output', 'wb') as file:
    file.write(response.content)


# case when the response is text
# Here unlikely if the reponse content is of type **iso-8859-1** we will have to override the response encoding
url = 'some_page_url'

response = get(url)
# override encoding by real educated guess as provided by chardet
r.encoding = r.apparent_encoding

with open('output', 'w', encoding='utf-8') as file:
    file.write(response.content)

Hopefully this helps others in an enterprise setting looking for a solution. My solution after much tinkering was the following:

Follow the steps in the following link to install legacy browser extension and gpo settings: https://support.google.com/chrome/a/answer/3019558?hl=en&ref_topic=3062034

Enabled legacy browser redirect for "file://" through chrome gpo configuration Google Chrome -> Legacy Browser Support -> "Websites to open in alternative browser"

Configure gpo to also install extension: https://chrome.google.com/webstore/detail/enable-local-file-links/nikfmfgobenbhmocjaaboihbeocackld that redirects file:// links to bypass chrome file:// link block.

The extension opens the links which then triggers google chrome to open the link in internet explorer. The result is IE opens a window, then opens the file/folder for the user, then IE closes itself.

In Kotlin language you can do it in this way:

val values = arrayOf(
    "cat",
    "dog",
    "chicken"
)

ArrayAdapter(
    this,
    android.R.layout.simple_spinner_item,
    values
).also {
    it.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
    spinner.adapter = it
}

I fix this problem following this steps:

1. Clean Solution
2. Close Visual Studio
3. Deleting /bin from the project directory
4. Restart Visual Studio
5. Rebuild Solution

Somehow I fiddled around and some how I got it to work:

<iframe src="http://www.example.com#inside" width="100%" height="100%" align="center" ></iframe>

I think this is the first time this code has been posted so share it

I know this is a very old thread but I was looking for a solution to the same problem and I came across this before eventually finding the answer and I wanted to just post it here so somebody else in my shoes would have a shorter trek across the internet.

****Note that you probably have to run cmd.exe as an administrator for this to work**

So here we go, open up the prompt (as an adminstrator) and go to your System32 directory. Then run

C:\Windows\System32>cd ras

Now you'll be in the ras directory. Now it's time to create a temporary file with our connection info that we will then append onto the rasphone.pbk file that will allow us to use the rasdial command.

So to create our temp file run:

C:\Windows\System32\ras>copy con temp.txt

Now it will let you type the contents of the file, which should look like this:

[CONNECTION NAME]
MEDIA=rastapi
Port=VPN2-0
Device=WAN Miniport (IKEv2)
DEVICE=vpn
PhoneNumber=vpn.server.address.com

So replace CONNECTION NAME and vpn.server.address.com with the desired connection name and the vpn server address you want.

Make a new line and press Ctrl+Z to finish and save.

Now we will append this onto the rasphone.pbk file that may or may not exist depending on if you already have network connections configured or not. To do this we will run the following command:

C:\Windows\System32\ras>type temp.txt >> rasphone.pbk

This will append the contents of temp.txt to the end of rasphone.pbk, or if rasphone.pbk doesn't exist it will be created. Now we might as well delete our temp file:

C:\Windows\System32\ras>del temp.txt

Now we can connect to our newly configured VPN server with the following command:

C:\Windows\System32\ras>rasdial "CONNECTION NAME" myUsername myPassword

When we want to disconnect we can run:

C:\Windows\System32\ras>rasdial /DISCONNECT

That should cover it! I've included a direct copy and past from the command line of me setting up a connection for and connecting to a canadian vpn server with this method:

Hope this helps.

Note: This assumes that you will declare constants for row and column indexes named COLUMN_HEADING_ROW, FIRST_COL, and LAST_COL, and that _xlSheet is the name of the ExcelSheet (using Microsoft.Interop.Excel)

First, define the range:

var columnHeadingsRange = _xlSheet.Range[
    _xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
    _xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];

Then, set the background color of that range:

columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;

Finally, set the font color:

columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;

And here's the code combined:

var columnHeadingsRange = _xlSheet.Range[
    _xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
    _xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];

columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;

columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;

I'd like to point out that if you want to play with threads in C++, if you use cout you can get some interesting results.

Consider this code:

#include <string>
#include <iostream>
#include <thread>

using namespace std;

void task(int taskNum, string msg) {
    for (int i = 0; i < 5; ++i) {
        cout << "#" << taskNum << ": " << msg << endl;
    }
}

int main() {
    thread t1(task, 1, "AAA");
    thread t2(task, 2, "BBB");
    t1.join();
    t2.join();
    return 0;
}

// g++ ./thread.cpp -o thread.out -ansi -pedantic -pthread -std=c++0x

Now, the output comes all shuffled. It can yield different results too, try executing several times:

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

You can use printf to get it right, or you can use mutex.

#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB

Have fun!

Try this:

def get_git_sha(git_dir='') {
    dir(git_dir) {

}

node(BUILD_NODE) {
    ...
    repo_SHA = get_git_sha('src/FooBar.git')
    echo repo_SHA
    ...
}

• http://localhost:8080/Callback

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

Can allso look at Array.Sort Method http://msdn.microsoft.com/en-us/library/aa311213(v=vs.71).aspx

Even easier: via the requests module.

import requests
get_response = requests.get(url='http://google.com')
post_data = {'username':'joeb', 'password':'foobar'}
# POST some form-encoded data:
post_response = requests.post(url='http://httpbin.org/post', data=post_data)

To send data that is not form-encoded, send it serialised as a string (example taken from the documentation):

import json
post_response = requests.post(url='http://httpbin.org/post', data=json.dumps(post_data))
# If using requests v2.4.2 or later, pass the dict via the json parameter and it will be encoded directly:
post_response = requests.post(url='http://httpbin.org/post', json=post_data)

To complete the other answers, in lodash 4 to ignore only undefined and null (And not properties like false) you can use a predicate in _.pickBy:

_.pickBy(obj, v !== null && v !== undefined)

Example below :

const obj = { a: undefined, b: 123, c: true, d: false, e: null};_x000D_
_x000D_
const filteredObject = _.pickBy(obj, v => v !== null && v !== undefined);_x000D_
_x000D_
console.log = (obj) => document.write(JSON.stringify(filteredObject, null, 2));_x000D_
console.log(filteredObject);

Implement the iteration as a recursive function.

Function Iterate( i , N )
  If i == N Then
      Exit Function
  End If
  [Code]
  If Condition1 Then
     Call Iterate( i+1, N );
     Exit Function
  End If

  [Code]
  If Condition2 Then
     Call Iterate( i+1, N );
     Exit Function
  End If
  Call Iterate( i+1, N );
End Function

Start with a call to Iterate( 1, N )

Found how.

First, configure the text of titleLabel (because of styles, i.e, bold, italic, etc). Then, use setTitleEdgeInsets considering the width of your image:

[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setTitle:title forState:UIControlStateNormal];
[button.titleLabel setFont:[UIFont boldSystemFontOfSize:10.0]];

// Left inset is the negative of image width.
[button setTitleEdgeInsets:UIEdgeInsetsMake(0.0, -image.size.width, -25.0, 0.0)]; 

After that, use setTitleEdgeInsets considering the width of text bounds:

[button setImage:image forState:UIControlStateNormal];

// Right inset is the negative of text bounds width.
[button setImageEdgeInsets:UIEdgeInsetsMake(-15.0, 0.0, 0.0, -button.titleLabel.bounds.size.width)];

Now the image and the text will be centered (in this example, the image appears above the text).

Cheers.

If you're hoping to use background-image: url(...);, I don't think you can. However, if you want to play with layering, you can do something like this:

<img class="bg" src="..." />

And then some CSS:

.bg
{
  width: 100%;
  z-index: 0;
}

You can now layer content above the stretched image by playing with z-indexes and such. One quick note, the image can't be contained in any other elements for the width: 100%; to apply to the whole page.

Here's a quick demo if you can't rely on background-size: http://jsfiddle.net/bB3Uc/

Do NOT loop through all cells!! There is a lot of overhead in communications between worksheets and VBA, for both reading and writing. Looping through all cells will be agonizingly slow. I'm talking hours.

Instead, load an entire sheet at once into a Variant array. In Excel 2003, this takes about 2 seconds (and 250 MB of RAM). Then you can loop through it in no time at all.

In Excel 2007 and later, sheets are about 1000 times larger (1048576 rows × 16384 columns = 17 billion cells, compared to 65536 rows × 256 columns = 17 million in Excel 2003). You will run into an "Out of memory" error if you try to load the whole sheet into a Variant; on my machine I can only load 32 million cells at once. So you have to limit yourself to the range you know has actual data in it, or load the sheet bit by bit, e.g. 30 columns at a time.

Option Explicit

Sub test()

    Dim varSheetA As Variant
    Dim varSheetB As Variant
    Dim strRangeToCheck As String
    Dim iRow As Long
    Dim iCol As Long

    strRangeToCheck = "A1:IV65536"
    ' If you know the data will only be in a smaller range, reduce the size of the ranges above.
    Debug.Print Now
    varSheetA = Worksheets("Sheet1").Range(strRangeToCheck)
    varSheetB = Worksheets("Sheet2").Range(strRangeToCheck) ' or whatever your other sheet is.
    Debug.Print Now

    For iRow = LBound(varSheetA, 1) To UBound(varSheetA, 1)
        For iCol = LBound(varSheetA, 2) To UBound(varSheetA, 2)
            If varSheetA(iRow, iCol) = varSheetB(iRow, iCol) Then
                ' Cells are identical.
                ' Do nothing.
            Else
                ' Cells are different.
                ' Code goes here for whatever it is you want to do.
            End If
        Next iCol
    Next iRow

End Sub

To compare to a sheet in a different workbook, open that workbook and get the sheet as follows:

Set wbkA = Workbooks.Open(filename:="C:\MyBook.xls")
Set varSheetA = wbkA.Worksheets("Sheet1") ' or whatever sheet you need

ngModel and ngChecked are not meant to be used together.

ngChecked is expecting an expression, so by saying ng-checked="true", you're basically saying that the checkbox will always be checked by default.

You should be able to just use ngModel, tied to a boolean property on your model. If you want something else, then you either need to use ngTrueValue and ngFalseValue (which only support strings right now), or write your own directive.

What is it exactly that you're trying to do? If you just want the first checkbox to be checked by default, you should change your model -- item1: true,.

Edit: You don't have to submit your form to debug the current state of the model, btw, you can just dump {{testModel}} into your HTML (or <pre>{{testModel|json}}</pre>). Also your ngModel attributes can be simplified to ng-model="testModel.item1".

Yes, but none of them will manage to produce readable enough code to worth the effort. You will spend more time trying to read the decompiled source with assembler blocks inside, than rewriting your old app from scratch.

I replaced the "localhost" with IP Address (Database server's public IP Address) in the jdbc Url then it worked.

jdbcUrl = "jdbc:oracle:thin:<user>@//localhost:1521/<Service Name>";

??

jdbcUrl = "jdbc:oracle:thin:<user>@//<Public IP Address>:1521/<Service Name>";

Here is the way I fixed this issue on ASP.NET

• First, you should add the nuget package Microsoft.AspNet.WebApi.Cors

• Then modify the file App_Start\WebApiConfig.cs

  public static class WebApiConfig    
  {
     public static void Register(HttpConfiguration config)
     {
        config.EnableCors();
  
        ...
     }    
  }
  

• Add this attribute on your controller class

  [EnableCors(origins: "*", headers: "*", methods: "*")]
  public class MyController : ApiController
  {  
      [AcceptVerbs("POST")]
      public IHttpActionResult Post([FromBody]YourDataType data)
      {
           ...
           return Ok(result);
      }
  }
  

• I was able to send json to the action by this way

  $http({
          method: 'POST',
          data: JSON.stringify(data),
          url: 'actionurl',
          headers: {
              'Content-Type': 'application/json; charset=UTF-8'
          }
      }).then(...)

I didn't understood this Im new to php css but as you've defined your CSS at element level, already your styles are applied to your PHP code

Your PHP code is to be used with HTML like this

<!DOCTYPE html>
<html>
  <head>
    <style>
    /* Styles Go Here */
    </style>
  </head>
  <body>
  <?php
   echo 'Whatever'; 
  ?>
  </body>
</html>

Also remember, you did not need to echo HTML using php, simply separate them out like this

<table>
  <tr>
    <td><?php echo 'Blah'; ?></td>
  </tr>
</table>

Send message resignFirstResponder to the textfiled that put it there. Please see this post for more information.

There is no such thing as array constant in Go.

Quoting from the Go Language Specification: Constants:

There are boolean constants, rune constants, integer constants, floating-point constants, complex constants, and string constants. Rune, integer, floating-point, and complex constants are collectively called numeric constants.

A Constant expression (which is used to initialize a constant) may contain only constant operands and are evaluated at compile time.

The specification lists the different types of constants. Note that you can create and initialize constants with constant expressions of types having one of the allowed types as the underlying type. For example this is valid:

func main() {
    type Myint int
    const i1 Myint = 1
    const i2 = Myint(2)
    fmt.Printf("%T %v\n", i1, i1)
    fmt.Printf("%T %v\n", i2, i2)
}

Output (try it on the Go Playground):

main.Myint 1
main.Myint 2

If you need an array, it can only be a variable, but not a constant.

I recommend this great blog article about constants: Constants

In an undirected graph (excluding multigraphs), the answer is n*(n-1)/2. In a directed graph an edge may occur in both directions between two nodes, then the answer is n*(n-1).

What is wrong with List.Find ??

I think we need more information on what you've done, and why it fails, before we can provide truly helpful answers.

using System.IO;
using System.Text;

using (StreamWriter sw = new StreamWriter(File.Open(myfilename, FileMode.Create), Encoding.WhateverYouWant))
{    
    sw.WriteLine("my text...");     
}

An alternate way of getting your encoding:

using System.IO;
using System.Text;

using (var sw  = new StreamWriter(File.Open(@"c:\myfile.txt", FileMode.CreateNew), Encoding.GetEncoding("iso-8859-1"))) {
    sw.WriteLine("my text...");             
}

Check out the docs for the StreamWriter constructor.

Here, if you want to control it through HTML: do like below Option 1:

<meta http-equiv="expires" content="Sun, 01 Jan 2014 00:00:00 GMT"/>
<meta http-equiv="pragma" content="no-cache" />

And if you want to control it through PHP: do it like below Option 2:

header('Expires: Sun, 01 Jan 2014 00:00:00 GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', FALSE);
header('Pragma: no-cache');

AND Option 2 IS ALWAYS BETTER in order to avoid proxy based caching issue.

In python, integers and strings are immutable and are passed by value. You cannot pass a string, or integer, to a function and expect the argument to be modified.

So to convert string limit="100" to a number, you need to do

limit = int(limit) # will return new object (integer) and assign to "limit"

If you really want to go around it, you can use a list. Lists are mutable in python; when you pass a list, you pass it's reference, not copy. So you could do:

def int_in_place(mutable):
    mutable[0] = int(mutable[0])

mutable = ["1000"]
int_in_place(mutable)
# now mutable is a list with a single integer

But you should not need it really. (maybe sometimes when you work with recursions and need to pass some mutable state).

ToggleButton inherits from TextView so you can set drawables to be displayed at the 4 borders of the text. You can use that to display the icon you want on top of the text and hide the actual text

<ToggleButton
    android:id="@+id/toggleButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawableTop="@android:drawable/ic_menu_info_details"
    android:gravity="center"
    android:textOff=""
    android:textOn=""
    android:textSize="0dp" />

The result compared to regular ToggleButton looks like

The seconds option is to use an ImageSpan to actually replace the text with an image. Looks slightly better since the icon is at the correct position but can't be done with layout xml directly.

You create a plain ToggleButton

<ToggleButton
    android:id="@+id/toggleButton3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="false" />

Then set the "text" programmatially

ToggleButton button = (ToggleButton) findViewById(R.id.toggleButton3);
ImageSpan imageSpan = new ImageSpan(this, android.R.drawable.ic_menu_info_details);
SpannableString content = new SpannableString("X");
content.setSpan(imageSpan, 0, 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
button.setText(content);
button.setTextOn(content);
button.setTextOff(content);

The result here in the middle - icon is placed slightly lower since it takes the place of the text.

To be on the safe side I find it better to define a cleanup function and call it from trap:

cleanup() {
        local pids=$(jobs -pr)
        [ -n "$pids" ] && kill $pids
}
trap "cleanup" INT QUIT TERM EXIT [...]

or avoiding the function altogether:

trap '[ -n "$(jobs -pr)" ] && kill $(jobs -pr)' INT QUIT TERM EXIT [...]

Why? Because by simply using trap 'kill $(jobs -pr)' [...] one assumes that there will be background jobs running when the trap condition is signalled. When there are no jobs one will see the following (or similar) message:

kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]

because jobs -pr is empty - I ended in that 'trap' (pun intended).
