The best solution is probably: use Modernizr.

However, if you necessarily want to use $.browser property, you can do it using jQuery Migrate plugin (for JQuery >= 1.9 - in earlier versions you can just use it) and then do something like:

if($.browser.chrome) {
   alert(1);
} else if ($.browser.mozilla) {
   alert(2);
} else if ($.browser.msie) {
   alert(3);
}

And if you need for some reason to use navigator.userAgent, then it would be:

$.browser.msie = /msie/.test(navigator.userAgent.toLowerCase()); 
$.browser.mozilla = /firefox/.test(navigator.userAgent.toLowerCase()); 

You can also try this:

<a href="" onclick="if (confirm('Delete selected item?')){return true;}else{event.stopPropagation(); event.preventDefault();};" title="Link Title">
    Link Text
</a>

On Windows 10 with Python 3.9.1, using the command line:

    py -V

Python 3.9.1

    py --version

Python 3.9.1

The "uni" in unistd stands for "UNIX" - you won't find it on a Windows system.

Most widely used, portable libraries should offer alternative builds or detect the platform and only try to use headers/functions that will be provided, so it's worth checking documentation to see if you've missed some build step - e.g. perhaps running "make" instead of loading a ".sln" Visual C++ solution file.

If you need to fix it yourself, remove the include and see which functions are actually needed, then try to find a Windows equivalent.

Check the items in forEach

    <c:forEach items="${pools}" var="pool"> 

        ${pool.name}

    </c:forEach>

Some times items="${pools}" has an extra space or it acts like string, retyping it should solve the issue.

You say it works once you install the VB6 IDE so the problem is likely to be that the components you are trying to use depend on the VB6 runtime being installed.

The VB6 runtime isn't installed on Windows by default.

Installing the IDE is one way to get the runtime. For non-developer machines, a "redistributable" installer package from Microsoft should be used instead.

Here is one VB6 runtime installer from Microsoft. I'm not sure if it will be the right version for your components:

http://www.microsoft.com/downloads/en/details.aspx?FamilyID=7b9ba261-7a9c-43e7-9117-f673077ffb3c

To check the version of R execute : R --version

Or after you are in the R shell print the contents of version$version.string

EDIT

To check the version of installed packages do the following.

After loading the library, you can execute sessionInfo ()

But to know the list of all installed packages:

packinfo <- installed.packages(fields = c("Package", "Version"))
packinfo[,c("Package", "Version")]

OR to extract a specific library version, once you have extracted the information using the installed.package function as above just use the name of the package in the first dimension of the matrix.

packinfo["RANN",c("Package", "Version")]
packinfo["graphics",c("Package", "Version")]

The above will print the versions of the RANN library and the graphics library.

It's unclear if the original problem was the same problem I had: wanting to max CPU threads on computation inside a loop while preserving the iterator's value and keeping inline to avoid passing a ton of variables to a worker function.

for (int i = 0; i < 300; i++)
{
    Task.Run(() => {
        var x = ComputeStuff(datavector, i); // value of i was incorrect
        var y = ComputeMoreStuff(x);
        // ...
    });
}

I got this to work by changing the outer iterator and localizing its value with a gate.

for (int ii = 0; ii < 300; ii++)
{
    System.Threading.CountdownEvent handoff = new System.Threading.CountdownEvent(1);
    Task.Run(() => {
        int i = ii;
        handoff.Signal();

        var x = ComputeStuff(datavector, i);
        var y = ComputeMoreStuff(x);
        // ...

    });
    handoff.Wait();
}

This probably has the same table to other schema the reason why you're getting that error.

You need to drop first the child row then the parent row.

Found this question searching on Google. This will return the first child of a element with class container, regardless as to what type the child is.

.container > *:first-child

}

For me doing a svn update, followed by svn commit worked. There were no .svn folders present in folder which was failing to add.

First things first, hover the mouse over the grey area below. Not part of the answer, but absolutely has to be said:

If you have a shell script that does "checkout, build, deploy" all by itself, then why are you using Jenkins? You are foregoing all the features of Jenkins that make it what it is. You might as well have a cron or an SVN post-commit hook call the script directly. Jenkins performing the SVN checkout itself is crucial. It allows the builds to be triggered only when there are changes (or on timer, or manual, if you prefer). It keeps track of changes between builds. It shows those changes, so you can see which build was for which set of changes. It emails committers when their changes caused successful or failed build (again, as configured as you prefer). It will email committers when their fixes fixed the failing build. And more and more. Jenkins archiving the artifacts also makes them available, per build, straight off Jenkins. While not as crucial as the SVN checkout, this is once again an integral part of what makes it Jenkins. Same with deploying. Unless you have a single environment, deployment usually happens to multiple environments. Jenkins can keep track of which environment a specific build (with specific set of SVN changes) is deployed it, through the use of Promotions. You are foregoing all of this. It sounds like you are told "you have to use Jenkins" but you don't really want to, and you are doing it just to get your bosses off your back, just to put a checkmark "yes, I've used Jenkins"

The short answer is: the exit code of last command of the Jenkin's Execute Shell build step is what determines the success/failure of the Build Step. 0 - success, anything else - failure. Note, this is determining the success/failure of the build step, not the whole job run. The success/failure of the whole job run can further be affected by multiple build steps, and post-build actions and plugins.

You've mentioned Build step 'Execute shell' marked build as failure, so we will focus just on a single build step. If your Execute shell build step only has a single line that calls your shell script, then the exit code of your shell script will determine the success/failure of the build step. If you have more lines, after your shell script execution, then carefully review them, as they are the ones that could be causing failure.

Finally, have a read here Jenkins Build Script exits after Google Test execution. It is not directly related to your question, but note that part about Jenkins launching the Execute Shell build step, as a shell script with /bin/sh -xe

The -e means that the shell script will exit with failure, even if just 1 command fails, even if you do error checking for that command (because the script exits before it gets to your error checking). This is contrary to normal execution of shell scripts, which usually print the error message for the failed command (or redirect it to null and handle it by other means), and continue.

To circumvent this, add set +e to the top of your shell script.

Since you say your script does all it is supposed to do, chances are the failing command is somewhere at the end of the script. Maybe a final echo? Or copy of artifacts somewhere? Without seeing the full console output, we are just guessing.

Please post the job run's console output, and preferably the shell script itself too, and then we could tell you exactly which line is failing.

select field1, field2, 'example' as TempField
from table1

This should work across different SQL implementations.

I know this is an old one with an accepted answer, and that answer works great.. IF you are not styling the background and floating the final inputs left. If you are, then the form background will not include the floated input fields.

To avoid this make the divs with the smaller input fields inline-block rather than float left.

This:

<div style="display:inline-block;margin-right:20px;">
    <label for="name">Name</label>
    <input id="name" type="text" value="" name="name">
</div>

Rather than:

<div style="float:left;margin-right:20px;">
    <label for="name">Name</label>
    <input id="name" type="text" value="" name="name">
</div>

In .NET the struct and class declarations differentiate between reference types and value types.

When you pass round a reference type there is only one actually stored. All the code that accesses the instance is accessing the same one.

When you pass round a value type each one is a copy. All the code is working on its own copy.

This can be shown with an example:

struct MyStruct 
{
    string MyProperty { get; set; }
}

void ChangeMyStruct(MyStruct input) 
{ 
   input.MyProperty = "new value";
}

...

// Create value type
MyStruct testStruct = new MyStruct { MyProperty = "initial value" }; 

ChangeMyStruct(testStruct);

// Value of testStruct.MyProperty is still "initial value"
// - the method changed a new copy of the structure.

For a class this would be different

class MyClass 
{
    string MyProperty { get; set; }
}

void ChangeMyClass(MyClass input) 
{ 
   input.MyProperty = "new value";
}

...

// Create reference type
MyClass testClass = new MyClass { MyProperty = "initial value" };

ChangeMyClass(testClass);

// Value of testClass.MyProperty is now "new value" 
// - the method changed the instance passed.

Classes can be nothing - the reference can point to a null.

Structs are the actual value - they can be empty but never null. For this reason structs always have a default constructor with no parameters - they need a 'starting value'.

This works too.

const $el = $(".myclass");
const className = $el[0].className;

In CSS:

SELECT OPTION:checked { background-color: red; }

At its most basic, concatenating files from a batch file is done with 'copy'.

copy file1.txt + file2.txt + file3.txt concattedfile.txt

Explicitly specifying the max_iter resolves the warning as the default max_iter is 100. [For Logistic Regression].

 logreg = LogisticRegression(max_iter=1000)

For bootstrap datetimepicker, assign decade value as follow:

$(".years").datetimepicker({
    format: "yyyy",
    startView: 'decade',
    minView: 'decade',
    viewSelect: 'decade',
    autoclose: true,
});

When you have a lot of variables that don't need escaping, you can use an autoescape block:

{% autoescape off %}
{{ something }}
{{ something_else }}
<b>{{ something_important }}</b>
{% endautoescape %}

You can use jsoup to parse any kind of web page. Here you can find the jsoup library and full source code.

Here is an example: http://desicoding.blogspot.com/2011/03/how-to-parse-html-in-java-jsoup.html

To install in Eclipse:

1. Right Click on project
2. BuildPath
3. Add External Archives
4. select the .jar file

You can parse according to tag/parent/child very comfortably

Another option is git merge --squash <feature branch> then finally do a git commit.

From Git merge

--squash

--no-squash

Produce the working tree and index state as if a real merge happened (except for the merge information), but do not actually make a commit or move the HEAD, nor record $GIT_DIR/MERGE_HEAD to cause the next git commit command to create a merge commit. This allows you to create a single commit on top of the current branch whose effect is the same as merging another branch (or more in case of an octopus).

Not entirely sure what you want here, but if you want to discount blank cells in the range and pass over zeros then this would do it; if a little contrived:

=MIN(IF(A1:E1=0,MAX(A1:E1),A1:E1))

With Ctrl+Shift+Enter as an array.

What I'm doing here is replacing zeros with the maximum value in the list.

Or use Series.tolist or Series.any:

>>> s = pd.Series(list('abc'))
>>> s
0    a
1    b
2    c
dtype: object
>>> 'a' in s.tolist()
True
>>> (s=='a').any()
True

Series.tolist makes a list about of a Series, and the other one i am just getting a boolean Series from a regular Series, then checking if there are any Trues in the boolean Series.

After reading the docs, I have to pass the name of the connection string instead:

var db = new NerdDinners("NerdDinnerDb");

The following site uses System.Management to accomplish the same is a very sleek way in a console application

Ubuntu 14.04

export GOPATH=$HOME/go

Additionally you can add this string to file

$HOME/.bashrc

Ok, solved my problem, if anyone is passing by here is the answer:

Just had to add left: 0, and top: 0, to the styles, and yes, I'm tired.

position: 'absolute',
left:     0,
top:      0,

don't you need double () for the values bit? if not try this (although there must be a better way

insert into this_table_archive (id, field_1, field_2, field_3) 
values
((select id from this_table where entry_date < '2001-01-01'), 
((select field_1 from this_table where entry_date < '2001-01-01'), 
((select field_2 from this_table where entry_date < '2001-01-01'), 
((select field_3 from this_table where entry_date < '2001-01-01'));

The working command I'm using to execute custom SQL statements is:

results = ActiveRecord::Base.connection.execute("foo")

with "foo" being the sql statement( i.e. "SELECT * FROM table").

This command will return a set of values as a hash and put them into the results variable.

So on my rails application_controller.rb I added this:

def execute_statement(sql)
  results = ActiveRecord::Base.connection.execute(sql)

  if results.present?
    return results
  else
    return nil
  end
end

Using execute_statement will return the records found and if there is none, it will return nil.

This way I can just call it anywhere on the rails application like for example:

records = execute_statement("select * from table")

"execute_statement" can also call NuoDB procedures, functions, and also Database Views.

Guys thank you for your help. I think all of this answers works. However i think my byte array contains raw bytes. That's why all of those solutions didnt work for my code.

However i found a solution. Maybe this solution helps other coders who have problem like mine.

static byte[] PadLines(byte[] bytes, int rows, int columns) {
   int currentStride = columns; // 3
   int newStride = columns;  // 4
   byte[] newBytes = new byte[newStride * rows];
   for (int i = 0; i < rows; i++)
       Buffer.BlockCopy(bytes, currentStride * i, newBytes, newStride * i, currentStride);
   return newBytes;
 }

 int columns = imageWidth;
 int rows = imageHeight;
 int stride = columns;
 byte[] newbytes = PadLines(imageData, rows, columns);

 Bitmap im = new Bitmap(columns, rows, stride, 
          PixelFormat.Format8bppIndexed, 
          Marshal.UnsafeAddrOfPinnedArrayElement(newbytes, 0));

 im.Save("C:\\Users\\musa\\Documents\\Hobby\\image21.bmp");

This solutions works for 8bit 256 bpp (Format8bppIndexed). If your image has another format you should change PixelFormat .

And there is a problem with colors right now. As soon as i solved this one i will edit my answer for other users.

*PS = I am not sure about stride value but for 8bit it should be equal to columns.

And also this function Works for me.. This function copies 8 bit greyscale image into a 32bit layout.

public void SaveBitmap(string fileName, int width, int height, byte[] imageData)
        {

            byte[] data = new byte[width * height * 4];

            int o = 0;

            for (int i = 0; i < width * height; i++)
            {
                byte value = imageData[i];


                data[o++] = value;
                data[o++] = value;
                data[o++] = value;
                data[o++] = 0; 
            }

            unsafe
            {
                fixed (byte* ptr = data)
                {

                    using (Bitmap image = new Bitmap(width, height, width * 4,
                                PixelFormat.Format32bppRgb, new IntPtr(ptr)))
                    {

                        image.Save(Path.ChangeExtension(fileName, ".jpg"));
                    }
                }
            }
        }

For users which have flavors in the project and found this thread:

Notice, that if your module dependency has different flavors, you should use one of the strategies:

1. Module that tightens dependencies should have the same flavors and dimensions as the dependency module
2. You should explicitly indicate which configuration you target in the module

Like that:

dependencies {
    compile project(path: ':module', configuration:'alphaDebug') 
}

You must get it via compatible way, others are deprecated:

Drawable drawable = ResourcesCompat.getDrawable(context.getResources(), R.drawable.my_drawable, null);

Here are some useful macros around NSLog I use a lot:

#ifdef DEBUG
#   define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)
#else
#   define DLog(...)
#endif

// ALog always displays output regardless of the DEBUG setting
#define ALog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)

The DLog macro is used to only output when the DEBUG variable is set (-DDEBUG in the projects's C flags for the debug confirguration).

ALog will always output text (like the regular NSLog).

The output (e.g. ALog(@"Hello world") ) will look like this:

-[LibraryController awakeFromNib] [Line 364] Hello world

This did it for me: (10 years later)

git log [--remotes] --no-walk --decorate

Since there is no stored information on branch creation times, what this does is display the first commit of each branch (--no-walk), which includes the date of the commit. Use --remotes for the remote branches, or omit it for local branches.

Since I do at least one commit in a branch before creating another one, this permitted me trace back a few months of branch creations (and feature dev-start) for documentation purposes.

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

I've had a similar problem. Still couldn't get content from my markdown files hosted on github.

After setting up a whitelist (with added github domain) to the $sceDelegateProvider in app.js it worked like a charm.

Description: Using a whitelist instead of wrapping as trusted if you load content from a different urls.

Docs: $sceDelegateProvider and ngInclude (for fetching, compiling and including external HTML fragment)

 $(this).attr("name") 

means the name of the select tag not option name.

To get option name

 $("#band_type_choices option:selected").attr('name');

            Console.WriteLine("Address: {0}", reply.Status);
         }
   });           
}

Found the solution.

In the parent I declare a new instance of the ChildClass() then bind the event handler in that class to the local method in the parent

In the child class I add a public event handler:

public EventHandler UpdateProgress;

In the parent I create a new instance of this child class then bind the local parent event to the public eventhandler in the child

ChildClass child = new ChildClass();
child.UpdateProgress += this.MyMethod;
child.LoadData(this.MyDataTable);

Then in the LoadData() of the child class I can call

private LoadData() {
    this.OnMyMethod();
}

Where OnMyMethod is:

public void OnMyMethod()
{
     // has the event handler been assigned?
     if (this.UpdateProgress!= null)
     {
         // raise the event
         this.UpdateProgress(this, new EventArgs());
     }
}

This runs the event in the parent class

If the Application.Current is null for example by unit test, you can try this:

 System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke( YOUR action )

As all the other answers show, the problem is that adding a std::string and a const char* using + results in a std::string, while system() expects a const char*. And the solution is to use c_str(). However, you can also do it without a temporary:

string name = "john";
system((" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str());

See it might be worked -------

UPDATE table_name SET column_name=replace(column_name, ' ', '') //Remove white space

UPDATE table_name SET column_name=replace(column_name, '\n', '') //Remove newline

UPDATE table_name SET column_name=replace(column_name, '\t', '') //Remove all tab

Thanks Subroto

Use WEEKDAY() instead of DAYOFWEEK(), it begins on Monday.

If you need to start at index 1, use or WEEKDAY() + 1.

Use a concrete list type, e.g. ArrayList instead of just List.

the easiest way is to change version in every pom.xml to arbitrary version. then check that dependency management to use the correct version of the module used in this module! for example, if u want increase versioning for a tow module project u must do like flowing:

in childe module :

    <parent>
       <artifactId>A-application</artifactId>
       <groupId>com.A</groupId>
       <version>new-version</version>
    </parent>

and in parent module :

<groupId>com.A</groupId>
<artifactId>A-application</artifactId>
<version>new-version</version>

You never give any value to your strings in main so they are empty, and thus obviously the function returns an empty string.

Replace:

string str1, str2, str3;

with:

string str1 = "the dog jumped over the fence";
string str2 = "the";
string str3 = "that";

Also, you have several problems in your replaceSubstring function:

int index = s1.find(s2, 0);
s1.replace(index, s2.length(), s3);

• std::string::find returns a std::string::size_type (aka. size_t) not an int. Two differences: size_t is unsigned, and it's not necessarily the same size as an int depending on your platform (eg. on 64 bits Linux or Windows size_t is unsigned 64 bits while int is signed 32 bits).
• What happens if s2 is not part of s1? I'll leave it up to you to find how to fix that. Hint: std::string::npos ;)

For those looking for a dplyr/tidyverse version. Building on Gavin Simpson solution:

# Create DF
set.seed(123)
x <- rnorm(100)
DF <- data.frame(x = x,
                 y = 4 + (1.5*x) + rnorm(100, sd = 2),
                 b = gl(5, 20))

# Change reference level
DF = DF %>% mutate(b = relevel(b, 3))

m2 <- lm(y ~ x + b, data = DF)
summary(m2)

Pandas timestamp differences returns a datetime.timedelta object. This can easily be converted into hours by using the *as_type* method, like so

import pandas
df = pandas.DataFrame(columns=['to','fr','ans'])
df.to = [pandas.Timestamp('2014-01-24 13:03:12.050000'), pandas.Timestamp('2014-01-27 11:57:18.240000'), pandas.Timestamp('2014-01-23 10:07:47.660000')]
df.fr = [pandas.Timestamp('2014-01-26 23:41:21.870000'), pandas.Timestamp('2014-01-27 15:38:22.540000'), pandas.Timestamp('2014-01-23 18:50:41.420000')]
(df.fr-df.to).astype('timedelta64[h]')

to yield,

0    58
1     3
2     8
dtype: float64

Here the output

It is not possible to dynamically change the value of a file field, otherwise you could set it to "c:\yourfile" and steal files very easily.

However there are many solutions to a multi-upload system. I'm guessing that you're wanting to have a multi-select open dialog.

Perhaps have a look at http://www.plupload.com/ - it's a very flexible solution to multiple file uploads, and supports drop zones e.t.c.

If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:

Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);

Hope it helps.

Internet Explorer, Safari, Chrome and Opera users need to remember to explicidly set the line-height value in CSS. I do a stylesheet that sets the initial properites for all text boxes as follows.

<style>
    TEXTAREA { line-height: 14px; font-size: 12px; font-family: arial }
</style>

For me, on Ubuntu, the various versions of JDK were in /usr/lib/jvm.

request.getAttribute("servletName") method will return Object that you need to cast to ArrayList

ArrayList<Category> list =new ArrayList<Category>();
//storing passed value from jsp
list = (ArrayList<Category>)request.getAttribute("servletName");

About access

<ol class="viewer-nav">
    <li *ngFor="let section of sections" 
        [attr.data-sectionvalue]="section.value"
        (click)="get_data($event)">
        {{ section.text }}
    </li>  
</ol>

And

get_data(event) {
   console.log(event.target.dataset.sectionvalue)
}

Use a bit of RegEx:

Regex.Match(Date.Now.ToString(), @"^.*?(?= )");

Produces a date in the format: dd/mm/yyyy

You may get day, month and year and may concatenate them or may use MM-dd-yyyy format as given below.

System.out.println("Formatted Date 2: " + mmddyyyy2);



LocalDateTime ldt1 = LocalDateTime.now();  
DateTimeFormatter format1 = DateTimeFormatter.ofPattern("MM-dd-yyyy");  
String mmddyyyy3 = ldt1.format(format1);

From my test (spring 3.0.5), @RequestMapping(value={"", "/"}) - only "/" works, "" does not. However I found out this works: @RequestMapping(value={"/", " * "}), the " * " matches anything, so it will be the default handler in case no others.

It can also be written this way

this.props.history.push(`${window.location.pathname}&page=${pageNumber}`)

In Spring Boot web app, with Jackson and JSR 310 version "2.8.5"

compile "com.fasterxml.jackson.core:jackson-databind:2.8.5"
runtime "com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.8.5"

The @JsonFormat works:

import com.fasterxml.jackson.annotation.JsonFormat;

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
private LocalDate birthDate;

I tried nearly all suggestions. However, the only thing that really solved the issue was:

1. Create an .htaccess in the same folder where your PHP file lies.

2. Add this line to the htaccess:

   Header always unset X-Frame-Options

Embedding the PHP by an iframe from another domain should work afterwards.

Additionally you could add in the beginning of your PHP file:

header('X-Frame-Options: ALLOW');

Which was, however, not necessary in my case.

This can be achieve by creating object of List data structure, as follows

List list = new ArrayList();

How to create a Multidimensional ArrayList in Java?

NSArray* foo = [@"10/04/2011" componentsSeparatedByString: @"/"];
NSString* firstBit = [foo objectAtIndex: 0];

Update 7/3/2018:

Now that the question has acquired a Swift tag, I should add the Swift way of doing this. It's pretty much as simple:

let substrings = "10/04/2011".split(separator: "/")
let firstBit = substrings[0]

Although note that it gives you an array of Substring. If you need to convert these back to ordinary strings, use map

let strings = "10/04/2011".split(separator: "/").map{ String($0) }
let firstBit = strings[0]

or

let firstBit = String(substrings[0])

or you can set pointer-events:none to your a element and pointer-event:all to your a:before element, and then add hover CSS to a element

a{
    pointer-events:none;
}
a:before{
    pointer-events:all
}
a:hover:before{
    background:blue;
}

Like you said, a jar is a zip file (not a special type, but just a plain old zip), so either library could be made to work. The reasoning is that the average person, seeing a *.zip extension, tends to unzip it. Since the app server wants it unzipped, a simple rename keeps people from unzipping it simply out of habit. Likewise, *.war file also should remain uncompressed.

java.util.jar basically just adds additional functionality to java.util.zip with very little extra overhead. Let the java.util.jar be a helper in posting, etc... and use it.

var isiOSSafari = (navigator.userAgent.match(/like Mac OS X/i)) ? true: false;

Based on the other answers it seems like this message has a lot of causes, I thought I'd just share my individual solution in case anyone has my exact problem in the future.

Our site loads the CSS files from an AWS Cloudfront distribution, which uses an S3 bucket as the origin. This particular S3 bucket was kept synced to a Linux server running Jenkins. The sync command via s3cmd sets the Content-Type for the S3 object automatically based on what the OS says (presumably based on the file extension). For some reason, in our server, all the types were being set correctly except .css files, which it gave the type text/plain. In S3, when you check the metadata in the properties of a file, you can set the type to whatever you want. Setting it to text/css allowed our site to correctly interpret the files as CSS and load correctly.

One option is to use do.call():

 > do.call(rbind, a)
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5
[10,]   10    1    2    3    4    5

This is the only thing that worked for me (with an ES6 class component):

componentDidMount() {
  ReactDOM.findDOMNode(this).scrollIntoView();
}

This is just a sample code, but it may help you get on your way:

Public Sub testIt()
    Workbooks("Workbook2").Activate
    ActiveWorkbook.Sheets("Sheet2").Activate
    ActiveSheet.Range("B3").Select
    ActiveCell.EntireRow.Insert
End Sub

I am assuming that you can open the book (called Workbook2 in the example).

I think (but I'm not sure) you can squash all this in a single line of code:

    Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert

This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit()

    // return JSON String
    return jObj;

I used Ctrl + F5 keyboard combination. By doing so, instead of reading from cache, I wanted to get a new response. The solution is to do hard refresh the page.

On MDN Web Docs:

"The HTTP 304 Not Modified client redirection response code indicates that there is no need to retransmit the requested resources. It is an implicit redirection to a cached resource."

You need to ensure that auto-commit on the Connection is turned off, or setFetchSize will have no effect.

dbConnection.setAutoCommit(false);

Edit: Remembered that when I used this fix it was Postgres-specific, but hopefully it will still work for SQL Server.

Yes, the order of elements in a python list is persistent.

Specify /D to change the drive also.

The code below was tested on iPhone, iPad (iOS13), Safari (Catalina). It was able to autoplay the YouTube video on all devices. Make sure the video is muted and the playsinline parameter is on. Those are the magic parameters that make it work.

I had this issue on my Windows grunt because I installed the 32 bit version of Node on a 64 bit Windows OS. When I installed the 64bit version specifically, it started working.

For those of us who this above valid solution didnt work, there's another workaround here

 searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View view, boolean isFocused) {
            if(!isFocused)
            {
                Toast.makeText(MainActivity.this,"not focused",Toast.LENGTH_SHORT).show();

            }
        }
    });

Just use

console.info("CONSOLE LOG : ")
console.log(response);
console.info("CONSOLE DIR : ")
console.dir(response);

and you will get this in chrome console :

CONSOLE LOG : 
facebookSDK_JS.html:56 Object {name: "Diego Matos", id: "10155988777540434"}
facebookSDK_JS.html:57 CONSOLE DIR :

Another example, this uses CSS, I simply put the form in a div with the container class. And specified that input elements contained within are to be 100% of the container width and not have any elements on either side.

.container {_x000D_
  width: 500px;_x000D_
  clear: both;_x000D_
}_x000D_
_x000D_
.container input {_x000D_
  width: 100%;_x000D_
  clear: both;_x000D_
}

<html>_x000D_
_x000D_
<head>_x000D_
  <title>Example form</title>_x000D_

This may hower not work on all types of 3D applications/video apps. Then this link may be more useful as it describes 3 different methods you can use.

Old answer (C#):
You can use System.Drawing.Graphics.Copy, but it is not very fast.

A sample project I wrote doing exactly this: http://blog.tedd.no/index.php/2010/08/16/c-image-analysis-auto-gaming-with-source/

I'm planning to update this sample using a faster method like Direct3D: http://spazzarama.com/2009/02/07/screencapture-with-direct3d/

And here is a link for capturing to video: How to capture screen to be video using C# .Net?

You could just vectorize the function and then apply it directly to a Numpy array each time you need it:

import numpy as np

def f(x):
    return x * x + 3 * x - 2 if x > 0 else x * 5 + 8

f = np.vectorize(f)  # or use a different name if you want to keep the original f

result_array = f(A)  # if A is your Numpy array

It's probably better to specify an explicit output type directly when vectorizing:

f = np.vectorize(f, otypes=[np.float])

I have re-wrote by hand, these encoding and decoding methods with the exception of the hexadecimal one into a modular format for cross-platform / browser compatibility and also with real private scoping, and uses btoa and atob if they exist due to speed rather than utilize its own encoding:

https://gist.github.com/Nijikokun/5192472

Usage:

base64.encode(/* String */);
base64.decode(/* String */);

utf8.encode(/* String */);
utf8.decode(/* String */);

In general you can say session.gc_maxlifetime specifies the maximum lifetime since the last change of your session data (not the last time session_start was called!). But PHP’s session handling is a little bit more complicated.

Because the session data is removed by a garbage collector that is only called by session_start with a probability of session.gc_probability devided by session.gc_divisor. The default values are 1 and 100, so the garbage collector is only started in only 1% of all session_start calls. That means even if the the session is already timed out in theory (the session data had been changed more than session.gc_maxlifetime seconds ago), the session data can be used longer than that.

Because of that fact I recommend you to implement your own session timeout mechanism. See my answer to How do I expire a PHP session after 30 minutes? for more details.

Add this little function and use it as so: $('div').scrollTo(500);

jQuery.fn.extend(
{
  scrollTo : function(speed, easing)
  {
    return this.each(function()
    {
      var targetOffset = $(this).offset().top;
      $('html,body').animate({scrollTop: targetOffset}, speed, easing);
    });
  }
});

Rand() does generate a uniform distribution of random numbers between 0 and 1, but the norminv (or norm.inv) function is taking the uniform distributed Rand() as an input to generate the normally distributed sample set.

Fairly straightforward:

git remote rm origin

As for the filter-branch question - just add --prune-empty to your filter branch command and it'll remove any revision that doesn't actually contain any changes in your resulting repo:

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD

You can try:

var headingDiv       = document.getElementById("head");
headingDiv.innerHTML = "<H3>Public Offers</H3>";

To fix your code you can simply change [Cov] to Cov.values, the first parameter of pd.DataFrame will become a multi-dimensional numpy array:

Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')

But the smartest solution still is use pd.read_excel with header=None and names=columns_list.

For bitwise | and Logicall ||

OR

bitwise & and logicall &&

it means if( a>b | a==0) in this first left a>b will be evaluated and then a==0 will be evaluated then | operation will be done

but in|| if a>b then if wont check for next RHS

Similarly for & and &&

if(A>0 & B>0)

it will evalue LHS and then RHS then do bitwise & but

in(A>0 && B>0)

if(A>0) is false(LHS) it will directly return false;

On Windows:-

Go to File -> Settings.

And open the 'Build,Execution,Deployment'. Then open the

I have another trick. Suppose you have 5 classes where a logout alert to be applied. Try with swift class extension.

File- New- Swift class- Name it.

Add the following:

public extension UIViewController
{

    func makeLogOutAlert()
    {
        var refreshAlert = UIAlertController(title: "Log Out", message: "Are You Sure to Log Out ? ", preferredStyle: UIAlertControllerStyle.Alert)

        refreshAlert.addAction(UIAlertAction(title: "Confirm", style: .Default, handler: { (action: UIAlertAction!) in
            self.navigationController?.popToRootViewControllerAnimated(true)
        }))

        refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .Default, handler: { (action: UIAlertAction!) in
            refreshAlert .dismissViewControllerAnimated(true, completion: nil)
        }))

        presentViewController(refreshAlert, animated: true, completion: nil)
    }
}

Implement using : self.makeLogOutAlert(). Hope it helps.

Unrelated, I'm sure, but do wrap your IDisposable objects in using blocks to ensure proper disposal:

        {
            Class1.CreateObject();
        }

            using (StreamWriter requestWriter = new StreamWriter(webStream, System.Text.Encoding.ASCII))
            {
                requestWriter.Write(DATA);
            }

            try

Looks like this behavior is how Ansible currently works, although there is a lot of interest in fixing it to work as desired. There's currently a pull request with the desired functionality so hopefully this will get incorporated into Ansible eventually.

Attach a Spinner Style using Java Code:

First, you need to a layout file such as below:

<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="?android:attr/spinnerDropDownItemStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="none"
android:minHeight="?android:attr/listPreferredItemHeight" />

Let us name it spinner_item.xml and place it inside res/layouts folder.

Next, Create a String ArrayList and put all the Spinner options inside it:

ArrayList<String> spinnerArray = new ArrayList<String>();
spinnerArray.add("Item No. 1");
spinnerArray.add("Item No. 2");
spinnerArray.add("Item No. 3");
spinnerArray.add("Item No. 4");

Finally, create the Spinner object and attach the style layout to it.

Spinner spinner = new Spinner(getActivity());
spinner.setTag("some_id");
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_dropdown_item, spinnerArray);                  spinnerArrayAdapter.setDropDownViewResource(R.layout.spinner_item);
spinner.setAdapter(spinnerArrayAdapter);

Note the Spinner(getActivity()) in the above line will be changed to Spinner(this) if you are writing this from inside Activity rather than from inside a fragment.

Thats all!

Attach a Spinner Style inside Android Layout File:

First, create a xml file the defines the style attribute (gradient_spinner.xml)

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item><layer-list>
        <item><shape>
            <gradient android:angle="90"  android:type="linear" />

            <stroke android:width="1dp" android:color="@color/colorBackground" />

            <corners android:radius="2dp" />

            <padding android:bottom="1dp" android:left="1dp" android:right="1dp" android:top="1dp" />
        </shape></item>
        <item android:right="5dp">
            <bitmap android:gravity="center_horizontal|right" android:src="@drawable/expand_icon">
            <padding android:right="2dp" />
        </bitmap>
        </item>
    </layer-list></item>

</selector>

Next, inside the style.xml file specify the style and call the gradient_spinner as background

<style name="spinner_style">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:background">@drawable/gradient_spinner</item>
<item name="android:layout_margin">1dp</item>
<item name="android:paddingLeft">5dp</item>
<item name="android:paddingRight">5dp</item>
<item name="android:paddingTop">5dp</item>
<item name="android:paddingBottom">5dp</item>
</style>

Finally, attach the above style to the Spinner:

<Spinner
   android:id="@+id/agent_id_spinner"
   android:layout_width="match_parent"
   android:layout_height="40dp"
   android:textSize="@dimen/title_text_view"
   style="@style/spinner_style"  />

Thats it!

(in answer to the second question) By only using a sign bit (and not 2's complement), you can end up with -0. Not very pretty.

In response to others:

You don't need to specify case in BASH4 just use the ',,' to make a var lowercase. Also I strongly dislike putting code inside of the read block, get the result and deal with it outside of the read block IMO. Also include a 'q' for quit IMO. Lastly why type 'yes' just use -n1 and have the press y.

Example: user can press y/n and also q to just quit.

ans=''
while true; do
    read -p "So is MikeQ the greatest or what (y/n/q) ?" -n1 ans
    case ${ans,,} in
        y|n|q) break;;
        *) echo "Answer y for yes / n for no  or q for quit.";;
    esac
done

echo -e "\nAnswer = $ans"

if [[ "${ans,,}" == "q" ]] ; then
        echo "OK Quitting, we will assume that he is"
        exit 0
fi

if [[ "${ans,,}" == "y" ]] ; then
        echo "MikeQ is the greatest!!"
else
        echo "No? MikeQ is not the greatest?"
fi

It can be achieved by using rjust:

line_new = word[0].rjust(10) + word[1].rjust(10) + word[2].rjust(10)

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

Source: is there a way to serialize pojo's directly to treemodel?

On Linux we can have these as exceptions, too.

Normally, when your program performs a segmentation fault, it is sent a SIGSEGV signal. You can set up your own handler for this signal and mitigate the consequences. Of course you should really be sure that you can recover from the situation. In your case, I think, you should debug your code instead.

Back to the topic. I recently encountered a library (short manual) that transforms such signals to exceptions, so you can write code like this:

try
{
    *(int*) 0 = 0;
}
catch (std::exception& e)
{
    std::cerr << "Exception caught : " << e.what() << std::endl;
}

Didn't check it, though. Works on my x86-64 Gentoo box. It has a platform-specific backend (borrowed from gcc's java implementation), so it can work on many platforms. It just supports x86 and x86-64 out of the box, but you can get backends from libjava, which resides in gcc sources.

Simply select the class, right click and choose rename (probably F2 will also do). You can also select the class name in the source file, right click, choose Source, Refactor and rename. In both cases, both the class and the filename will be changed.

var x : IHash = {};
x['key1'] = 'value1';
x['key2'] = 'value2';

console.log(x['key1']);
// outputs value1

console.log(x['key2']);
// outputs value2

If you would like to then iterate through your dictionary, you can use.

Object.keys(x).forEach((key) => {console.log(x[key])});

Object.keys returns all the properties of an object, so it works nicely for returning all the values from dictionary styled objects.

You also mentioned a hashmap in your question, the above definition is for a dictionary style interface. Therefore the keys will be unique, but the values will not.

You could use it like a hashset by just assigning the same value to the key and its value.

if you wanted the keys to be unique and with potentially different values, then you just have to check if the key exists on the object before adding to it.

var valueToAdd = 'one';
if(!x[valueToAdd])
   x[valueToAdd] = valueToAdd;

or you could build your own class to act as a hashset of sorts.

Class HashSet{
  private var keys: IHash = {};
  private var values: string[] = [];

  public Add(key: string){
    if(!keys[key]){
      values.push(key);
      keys[key] = key;
    }
  }

  public GetValues(){
    // slicing the array will return it by value so users cannot accidentally
    // start playing around with your array
    return values.slice();
  }
}

Setting the slice to nil is the best way to clear a slice. nil slices in go are perfectly well behaved and setting the slice to nil will release the underlying memory to the garbage collector.

See playground

package main

import (
    "fmt"
)

func dump(letters []string) {
    fmt.Println("letters = ", letters)
    fmt.Println(cap(letters))
    fmt.Println(len(letters))
    for i := range letters {
        fmt.Println(i, letters[i])
    }
}

func main() {
    letters := []string{"a", "b", "c", "d"}
    dump(letters)
    // clear the slice
    letters = nil
    dump(letters)
    // add stuff back to it
    letters = append(letters, "e")
    dump(letters)
}

Prints

letters =  [a b c d]
4
4
0 a
1 b
2 c
3 d
letters =  []
0
0
letters =  [e]
1
1
0 e

Note that slices can easily be aliased so that two slices point to the same underlying memory. The setting to nil will remove that aliasing.

This method changes the capacity to zero though.

According to Microsoft documentation, should NEVER use async void

Do not do this: The following example uses async void which makes the HTTP request complete when the first await is reached:

• Which is ALWAYS a bad practice in ASP.NET Core apps.

• Accesses the HttpResponse after the HTTP request is complete.

• Crashes the process.

If you have config file transforms then ensure you have the correct config selected within your publish profile. (Publish > Settings > Configuration)

Flattening image and applying background image is straight forward in ImageMagick

However, order of the commands is very important

To apply any background on a transparent image and flatten it, first apply the background than flatten it. The reverse doesn't work.

$ convert sourceimage.png -background BackgroundColor -flatten destinationimage.png

By using this way you can get the list of selected records.

GregorianCalendar gregorianCalendar = new GregorianCalendar();
Criteria cri = session.createCriteria(ProjectActivities.class);
cri.add(Restrictions.ge("EffectiveFrom", gregorianCalendar.getTime()));
List list = cri.list();

All the Records will be generated into list which are greater than or equal to '08-Oct-2012' or else pass the date of user acceptance date at 2nd parameter of Restrictions (gregorianCalendar.getTime()) of criteria to get the records.

When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[] For example: if your radio button is:

<input type="radio" name="rdb" value="male"/>

then in your php code you need to use:

$rdb_value = $_POST['rdb'];

You are probably trying to create a foreign key in some table which exists with the same name in previously existing tables. Use the following format to name your foreign key

tablename_columnname_fk

I've used the following method to detect if a string contains only whitespace. It also matches empty strings.

if (/^\s*$/.test(myStr)) {
  // the string contains only whitespace
}

Currently the only way I've found is with Deploy Tokens

If you use .Net 4.5 you can also use standard .Net json serializer:

using System.Runtime.Serialization.Json;
...    
Stream jsonSource = ...; // serializer will read data stream
var s = new DataContractJsonSerializer(typeof(string[][]));
var j = (string[][])s.ReadObject(jsonSource);

In .Net 4.5 and older you can use JavaScriptSerializer class:

using System.Web.Script.Serialization;
...
JavaScriptSerializer serializer = new JavaScriptSerializer();
string[][] list = serializer.Deserialize<string[][]>(json);

I was seeing this error unrelated to rails. It turned out my test was trying to use a port that was too high (greater than 65535).

This code will produce the error in question

require 'socket'
Socket.getaddrinfo("127.0.0.1", "65536")

You don't need the SELECT

DECLARE @LastChangeDate as date
SET @LastChangeDate = GetDate()

// file Foo.php
class Foo
{
  static function init() { /* ... */ }
}

Foo::init();

This way, the initialization happens when the class file is included. You can make sure this only happens when necessary (and only once) by using autoloading.

You can use the required html attribute if you want:

@Html.TextBoxFor(m => m.ShortName, 
new { @class = "form-control", placeholder = "short name", required="required"})

or you can use the RequiredAttribute class in .Net. With jQuery the RequiredAttribute can Validate on the front end and server side. If you want to go the MVC route, I'd suggest reading Data annotations MVC3 Required attribute.

OR

You can get really advanced:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = new Dictionary<string, object>(
    Html.GetUnobtrusiveValidationAttributes(ViewData.TemplateInfo.HtmlFieldPrefix));

 attributes.Add("class", "form-control");
 attributes.Add("placeholder", "short name");

  if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
  {
   attributes.Add("required", "required");
  }

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

or if you need it for multiple editor templates:

public static class ViewPageExtensions
{
  public static IDictionary<string, object> GetAttributes(this WebViewPage instance)
  {
    // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
    var attributes = new Dictionary<string, object>(
      instance.Html.GetUnobtrusiveValidationAttributes(
         instance.ViewData.TemplateInfo.HtmlFieldPrefix));

    if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
    {
      attributes.Add("required", "required");
    }
  }
}

then in your templates:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = this.GetAttributes();

  attributes.Add("class", "form-control");
  attributes.Add("placeholder", "short name");

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

Update 1 (for Tomas who is unfamilar with ViewData).

What's the difference between ViewData and ViewBag?

Excerpt:

So basically it (ViewBag) replaces magic strings:

ViewData["Foo"]

with magic properties:

ViewBag.Foo

The easiest way to serve static files is to use "harp". It can be found here. You can serve up your files from the location you want via node is:

This is how a byte should be shown to a human:

function bytesToHuman(bytes, decimals = 2) {
  // https://en.wikipedia.org/wiki/Orders_of_magnitude_(data)
  const units = ["bytes", "KiB", "MiB", "GiB", "TiB", "PiB", "EiB"]; // etc

  let i = 0;
  let h = 0;

  let c = 1 / 1023; // change it to 1024 and see the diff

  for (; h < c && i < units.length; i++) {
    if ((h = Math.pow(1024, i) / bytes) >= c) {
      break;
    }
  }

  // remove toFixed and let `locale` controls formatting
  return (1 / h).toFixed(decimals).toLocaleString() + " " + units[i];
}

// test
for (let i = 0; i < 9; i++) {
  let val = i * Math.pow(10, i);
  console.log(val.toLocaleString() + " bytes is the same as " + bytesToHuman(val));

}

// let's fool around
console.log(bytesToHuman(1023));
console.log(bytesToHuman(1024));
console.log(bytesToHuman(1025));

I had the same problem and apparently is solved now, despite this and some other gdi+ exceptions are very misleading, I found that actually the problem was that the parameter being sent to a Bitmap constructor was not valid. I have this code:

using (System.IO.FileStream fs = new System.IO.FileStream(inputImage, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite))
{
    try
    {
        using (Bitmap bitmap = (Bitmap)Image.FromStream(fs, true, false))
        {
            try
            {
                bitmap.Save(OutputImage + ".bmp", System.Drawing.Imaging.ImageFormat.Bmp);
                GC.Collect();
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
    }
    catch (ArgumentException aex)
    {
        throw new Exception("The file received from the Map Server is not a valid jpeg image", aex);
    }
}

The following line was causing an error:

Bitmap bitmap = (Bitmap)Image.FromStream(fs, true, false)

The file stream was built from the file downloaded from the Map Server. My app was sending the request incorrectly to get the image, and the server was returning something with the jpg extension, but was actually a html telling me that an error ocurred. So I was taking that image and trying to build a Bitmap with it. The fix was to control/ validate the image for a valid jpeg image.

Hope it helps!

Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:

• Prepare your proxy server - install IIS, Apache
• Get valid SSL certificate to avoid security errors (free from startssl.com for example)
• Write a wrapper, which will download insecure content (how to below)
• From your site/app get https://yourproxy.com/?page=http://insecurepage.com

If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

Connection object is for illustration only. The DataAdapter is the key bit:

Dim strSql As String = "SELECT EmpCode,EmpID,EmpName FROM dbo.Employee"
Dim dtb As New DataTable
Using cnn As New SqlConnection(connectionString)
  cnn.Open()
  Using dad As New SqlDataAdapter(strSql, cnn)
    dad.Fill(dtb)
  End Using
  cnn.Close()

For any given string s:

int(s, 16)

value_counts omits NaN by default so you're most likely dealing with "".

So you can just filter them out like

filter = df["Tenant"] != ""
dfNew = df[filter]

you need to use ++$counter, not $++counter, hence the reason it isn't working..

There is a nice trick: wrap the data with pandas DataFrame.

import pandas as pd
data = [[1, 2], [3, 4]]
pd.DataFrame(data, columns=["Foo", "Bar"])

It displays data like:

  | Foo | Bar |
0 | 1   | 2   |
1 | 3   | 4   |

or

sudo easy_install-2.7 PIL

As Ben said, you are POSTing your request ( HttpMethod.Post specified in your code )

The querystring (get) parameters included in your url probably will not do anything.

Try this:

string url = "http://myserver/method";    
string content = "param1=1&param2=2";
HttpClientHandler handler = new HttpClientHandler();
HttpClient httpClient = new HttpClient(handler);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
HttpResponseMessage response = await httpClient.SendAsync(request,content);

It makes it possible to bind member variables and functions in the uniform manner. The following is example with your Car class. More common usage would be binding std::pair::first and ::second when using in STL algorithms and Boost on a map.

#include <list>
#include <algorithm>
#include <iostream>
#include <iterator>
#include <boost/lambda/lambda.hpp>
#include <boost/lambda/bind.hpp>


class Car {
public:
    Car(int s): speed(s) {}
    void drive() {
        std::cout << "Driving at " << speed << " km/h" << std::endl;
    }
    int speed;
};

int main() {

    using namespace std;
    using namespace boost::lambda;

    list<Car> l;
    l.push_back(Car(10));
    l.push_back(Car(140));
    l.push_back(Car(130));
    l.push_back(Car(60));

    // Speeding cars
    list<Car> s;

    // Binding a value to a member variable.
    // Find all cars with speed over 60 km/h.
    remove_copy_if(l.begin(), l.end(),
                   back_inserter(s),
                   bind(&Car::speed, _1) <= 60);

    // Binding a value to a member function.
    // Call a function on each car.
    for_each(s.begin(), s.end(), bind(&Car::drive, _1));

    return 0;
}

1. Create Folder “resources” under Java Resources folder if your project doesn’t have it.
   2. create config.properties file with below value.

/Java Resources/resources/config.properties

for loading properties.

Properties prop = new Properties();
InputStream input = null;

try {

      input = getClass().getClassLoader().getResourceAsStream("config.properties");


    // load a properties file
    prop.load(input);

    // get the property value and print it out
    System.out.println(prop.getProperty("database"));
    System.out.println(prop.getProperty("dbuser"));
    System.out.println(prop.getProperty("dbpassword"));

} catch (IOException ex) {
    ex.printStackTrace();
} finally {
    if (input != null) {
        try {
            input.close();
        } catch (IOException e) {

The parent directory of an included file would be

dirname(getcwd())

e.g. the file is /var/www/html/folder/inc/file.inc.php which is included in /var/www/html/folder/index.php

then by calling /file/index.php

getcwd() is /var/www/html/folder  
__DIR__ is /var/www/html/folder/inc  
so dirname(__DIR__) is /var/www/html/folder

but what we want is /var/www/html which is dirname(getcwd())

pt_kill has an option for such. But it is on-demand, not continually monitoring. It does what @Rafa suggested. However see --sentinel for a hint of how to come close with cron.

Adding on top of majkinetor's answer, here is the way of removing trailing delimiter(since I cannot just comment under his answer yet):

ls -1 | awk 'ORS=","' | head -c -1

Just remove as many trailing bytes as your delimiter counts for.

I like this approach because I can use multi character delimiters + other benefits of awk:

ls -1 | awk 'ORS=", "' | head -c -2

EDIT

As Peter has noticed, negative byte count is not supported in native MacOS version of head. This however can be easily fixed.

First, install coreutils. "The GNU Core Utilities are the basic file, shell and text manipulation utilities of the GNU operating system."

brew install coreutils

Commands also provided by MacOS are installed with the prefix "g". For example gls.

Once you have done this you can use ghead which has negative byte count, or better, make alias:

alias head="ghead"

the best explanation i've found is this:

What is the difference betwen INTEGER and NUMBER? When should we use NUMBER and when should we use INTEGER? I just wanted to update my comments here...

NUMBER always stores as we entered. Scale is -84 to 127. But INTEGER rounds to whole number. The scale for INTEGER is 0. INTEGER is equivalent to NUMBER(38,0). It means, INTEGER is constrained number. The decimal place will be rounded. But NUMBER is not constrained.

• INTEGER(12.2) => 12
• INTEGER(12.5) => 13
• INTEGER(12.9) => 13
• INTEGER(12.4) => 12
• NUMBER(12.2) => 12.2
• NUMBER(12.5) => 12.5
• NUMBER(12.9) => 12.9
• NUMBER(12.4) => 12.4

INTEGER is always slower then NUMBER. Since integer is a number with added constraint. It takes additional CPU cycles to enforce the constraint. I never watched any difference, but there might be a difference when we load several millions of records on the INTEGER column. If we need to ensure that the input is whole numbers, then INTEGER is best option to go. Otherwise, we can stick with NUMBER data type.

You can use a generated id and name everytime, which is different, so the browser cannot remember this text-field and will fail to suggest some values.

This is at least the cross browser safe alternative, but I would recommend to go with the answer from RobertsonM (autocomplete="off").

In your code snippet, you could also resolve this by providing an implementation for the __new__ method in the subclass, likewise:

def G(F):
    def __new__(cls):
        # do something here

But this is a hack and I advise you against it, unless you know what you are doing. For nearly all cases I advise you to use the abc module, that others before me have suggested.

Also when you create a new (base) class, make it subclass object, like this: class MyBaseClass(object):. I don't know if it is that much significant anymore, but it helps retain style consistency on your code

In new APIs don't forget about TAG:

notify(String tag, int id, Notification notification)

and correspondingly

cancel(String tag, int id) 

instead of:

cancel(int id)

https://developer.android.com/reference/android/app/NotificationManager

Or if you still want to use formatter created from pattern you can just use LocalDateTime instead of Instant:

LocalDateTime datetime = LocalDateTime.now();
DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").format(datetime)

To define a checked exception you create a subclass (or hierarchy of subclasses) of java.lang.Exception. For example:

public class FooException extends Exception {
  public FooException() { super(); }
  public FooException(String message) { super(message); }
  public FooException(String message, Throwable cause) { super(message, cause); }
  public FooException(Throwable cause) { super(cause); }
}

Methods that can potentially throw or propagate this exception must declare it:

public void calculate(int i) throws FooException, IOException;

... and code calling this method must either handle or propagate this exception (or both):

try {
  int i = 5;
  myObject.calculate(5);
} catch(FooException ex) {
  // Print error and terminate application.
  ex.printStackTrace();
  System.exit(1);
} catch(IOException ex) {
  // Rethrow as FooException.
  throw new FooException(ex);
}

You'll notice in the above example that IOException is caught and rethrown as FooException. This is a common technique used to encapsulate exceptions (typically when implementing an API).

Sometimes there will be situations where you don't want to force every method to declare your exception implementation in its throws clause. In this case you can create an unchecked exception. An unchecked exception is any exception that extends java.lang.RuntimeException (which itself is a subclass of java.lang.Exception):

public class FooRuntimeException extends RuntimeException {
  ...
}

Methods can throw or propagate FooRuntimeException exception without declaring it; e.g.

public void calculate(int i) {
  if (i < 0) {
    throw new FooRuntimeException("i < 0: " + i);
  }
}

Unchecked exceptions are typically used to denote a programmer error, for example passing an invalid argument to a method or attempting to breach an array index bounds.

The java.lang.Throwable class is the root of all errors and exceptions that can be thrown within Java. java.lang.Exception and java.lang.Error are both subclasses of Throwable. Anything that subclasses Throwable may be thrown or caught. However, it is typically bad practice to catch or throw Error as this is used to denote errors internal to the JVM that cannot usually be "handled" by the programmer (e.g. OutOfMemoryError). Likewise you should avoid catching Throwable, which could result in you catching Errors in addition to Exceptions.

const a = {
  foods: {
    dinner: 'Pasta'
  }
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta

Using JSON.stringify and JSON.parse is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.

Considering larsks' answer, you can get it working with a single command with "--force":

 git mv --force myfile MyFile

This seems much simpler than accepted solution - does it have shortcomings I'm not considering? Came here looking for some dead-simple copy pasta.

import threading, time

def print_every_n_seconds(n=2):
    while True:
        print(time.ctime())
        time.sleep(n)
    
thread = threading.Thread(target=print_every_n_seconds, daemon=True)
thread.start()

Which asynchronously outputs.

#Tue Oct 16 17:29:40 2018
#Tue Oct 16 17:29:42 2018
#Tue Oct 16 17:29:44 2018

This does have drift. If the task being run takes appreciable amount of time, then the interval becomes 2 seconds + task time, so if you need precise scheduling then this is not for you.**

Note the daemon=True flag means this thread won't block the app from shutting down. For example, had issue where pytest would hang indefinitely after running tests waiting for this thead to cease.

To add a new column, 'e', to the existing data frame

 df1.loc[:,'e'] = Series(np.random.randn(sLength))

It should be:

SELECT SalesID, COUNT(*)
FROM AXDelNotesNoTracking
GROUP BY SalesID
HAVING COUNT(*) > 1

Regarding your initial query:

1. You cannot do a SELECT * since this operation requires a GROUP BY and columns need to either be in the GROUP BY or in an aggregate function (i.e. COUNT, SUM, MIN, MAX, AVG, etc.)
2. As this is a GROUP BY operation, a HAVING clause will filter it instead of a WHERE

Edit:

And I just thought of this, if you want to see WHICH items are in there more than once (but this depends on which database you are using):

;WITH cte AS (
    SELECT  *, ROW_NUMBER() OVER (PARTITION BY SalesID ORDER BY SalesID) AS [Num]
    FROM    AXDelNotesNoTracking
)
SELECT  *
FROM    cte
WHERE   cte.Num > 1

Of course, this just shows the rows that have appeared with the same SalesID but does not show the initial SalesID value that has appeared more than once. Meaning, if a SalesID shows up 3 times, this query will show instances 2 and 3 but not the first instance. Still, it might help depending on why you are looking for multiple SalesID values.

Edit2:

The following query was posted by APC below and is better than the CTE I mention above in that it shows all rows in which a SalesID has appeared more than once. I am including it here for completeness. I merely added an ORDER BY to keep the SalesID values grouped together. The ORDER BY might also help in the CTE above.

SELECT *
FROM AXDelNotesNoTracking
WHERE SalesID IN
    (     SELECT SalesID
          FROM AXDelNotesNoTracking
          GROUP BY SalesID
          HAVING COUNT(*) > 1
    )
ORDER BY SalesID

SQL Server Express does not come with profiler, but you can use SQL Server 2005/2008 Express Profiler instead.

The assert statement exists in almost every programming language. It helps detect problems early in your program, where the cause is clear, rather than later when some other operation fails.

When you do...

assert condition

... you're telling the program to test that condition, and immediately trigger an error if the condition is false.

In Python, it's roughly equivalent to this:

if not condition:
    raise AssertionError()

Try it in the Python shell:

>>> assert True # nothing happens
>>> assert False
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError

Assertions can include an optional message, and you can disable them when running the interpreter.

To print a message if the assertion fails:

assert False, "Oh no! This assertion failed!"

Do not use parenthesis to call assert like a function. It is a statement. If you do assert(condition, message) you'll be running the assert with a (condition, message) tuple as first parameter.

As for disabling them, when running python in optimized mode, where __debug__ is False, assert statements will be ignored. Just pass the -O flag:

python -O script.py

See here for the relevant documentation.

Let me explain how to get stacktraces that are reasonably complete in all browsers.

Error handling in JavaScript

Modern Chrome and Opera fully support the HTML 5 draft spec for ErrorEvent and window.onerror. In both of these browsers you can either use window.onerror, or bind to the 'error' event properly:

// Only Chrome & Opera pass the error object.
window.onerror = function (message, file, line, col, error) {
    console.log(message, "from", error.stack);
    // You can send data to your server
    // sendError(data);
};
// Only Chrome & Opera have an error attribute on the event.
window.addEventListener("error", function (e) {
    console.log(e.error.message, "from", e.error.stack);
    // You can send data to your server
    // sendError(data);
})

Unfortunately Firefox, Safari and IE are still around and we have to support them too. As the stacktrace is not available in window.onerror we have to do a little bit more work.

It turns out that the only thing we can do to get stacktraces from errors is to wrap all of our code in a try{ }catch(e){ } block and then look at e.stack. We can make the process somewhat easier with a function called wrap that takes a function and returns a new function with good error handling.

function wrap(func) {
    // Ensure we only wrap the function once.
    if (!func._wrapped) {
        func._wrapped = function () {
            try{
                func.apply(this, arguments);
            } catch(e) {
                console.log(e.message, "from", e.stack);
                // You can send data to your server
                // sendError(data);
                throw e;
            }
        }
    }
    return func._wrapped;
};

This works. Any function that you wrap manually will have good error handling, but it turns out that we can actually do it for you automatically in most cases.

By changing the global definition of addEventListener so that it automatically wraps the callback we can automatically insert try{ }catch(e){ } around most code. This lets existing code continue to work, but adds high-quality exception tracking.

var addEventListener = window.EventTarget.prototype.addEventListener;
window.EventTarget.prototype.addEventListener = function (event, callback, bubble) {
    addEventListener.call(this, event, wrap(callback), bubble);
}

We also need to make sure that removeEventListener keeps working. At the moment it won't because the argument to addEventListener is changed. Again we only need to fix this on the prototype object:

var removeEventListener = window.EventTarget.prototype.removeEventListener;
window.EventTarget.prototype.removeEventListener = function (event, callback, bubble) {
    removeEventListener.call(this, event, callback._wrapped || callback, bubble);
}

Transmit error data to your backend

You can send error data using image tag as follows

function sendError(data) {
    var img = newImage(),
        src = 'http://yourserver.com/jserror&data=' + encodeURIComponent(JSON.stringify(data));

    img.crossOrigin = 'anonymous';
    img.onload = function success() {
        console.log('success', data);
    };
    img.onerror = img.onabort = function failure() {
        console.error('failure', data);
    };
    img.src = src;
}

I found that, sometimes, nuget packages will install (what I'm guessing are) .NET Core required components or other items that conflict with the already-installed framework. My solution there was to open the project (.csproj) file and remove those references. For example, System.IO, System.Threading and such, tend to be added when Microsoft.Bcl is included via some recently installed NuGet package. There's no reason for specific versions of those in my projects, so I remove the references and the project builds. Hope that helps.

You can search your project file for "reference" and remove the conflicts. If they're included in System, get rid of them, and the build should work. This may not answer all cases of this issue - I'm making sure you know what worked for me :)

As has been pointed out in some other answers and comments, what you are missing here is a call to the JVM System class to print out the string generated by your toString() method.

LinkedList myLinkedList = new LinkedList();
System.out.println(myLinkedList.toString());

This will get the job done, but I wouldn't recommend doing it that way. If we take a look at the javadocs for the Object class, we find this description for toString():

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The emphasis added there is my own. You are creating a string that contains the entire state of the linked list, which somebody using your class is probably not expecting. I would recommend the following changes:

1. Add a toString() method to your LinkedListNode class.
2. Update the toString() method in your LinkedList class to be more concise.
3. Add a new method called printList() to your LinkedList class that does what you are currently expecting toString() to do.

In LinkedListNode:

public String toString(){
   return "LinkedListNode with data: " + getData();
}

In LinkedList:

public int size(){
    int currentSize = 0;
    LinkedListNode current = head;
    while(current != null){
        currentSize = currentSize + 1;
        current = current.getNext();
    }

    return currentSize;
}

[Note: edited to modernize ggplot syntax]

Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot. One advantage is that ggplot works with data.frames directly.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.

library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  xlab("My x label") +
  ylab("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area("Nitrogen") + 
  scale_x_continuous("My x label") +
  scale_y_continuous("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  labs(size= "Nitrogen",
       x = "My x label",
       y = "My y label",
       title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

which gives an identical figure to the one above.

http://fetchak.com/ie-css3/ works for IE 6+. Use this if css3pie doesn't work for you.

>>> class A(object): pass

>>> e = A()
>>> e
<__main__.A object at 0xb6d464ec>
>>> print type(e)
<class '__main__.A'>
>>> print type(e).__name__
A
>>> 

what do you mean by convert into a string? you can define your own repr and str_ methods:

>>> class A(object):
    def __repr__(self):
        return 'hei, i am A or B or whatever'

>>> e = A()
>>> e
hei, i am A or B or whatever
>>> str(e)
hei, i am A or B or whatever

or i dont know..please add explainations ;)

another alternative, just in case you want to have a shell script which creates the database if it does not exist and otherwise just keeps it as it is:

psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'my_db'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE my_db"

I found this to be helpful in devops provisioning scripts, which you might want to run multiple times over the same instance.

For those of you who would like an explanation:

-c = run command in database session, command is given in string
-t = skip header and footer
-q = silent mode for grep 
|| = logical OR, if grep fails to find match run the subsequent command

Try the following:

Followed by:

The simplest trick is to open the NIB file and do these two simple steps:

1. Just toggle that and set it to the one you prefer:

2. Select those UIView's/UIIMageView's/... that you want to be moved down. In my case only the logo was overlapped an I've set the delta to +15; (OR -15 if you chose iOS 7 in step 1)

And the result:

For those have same problem in Grails ckeditor plugin Give

filebrowserUploadUrl:'/YourAppName/ck/ofm'

to invoke the function that handles image uploade.if you want use your own customized function you can give that file path.

You cant style the alt attribute directly in css. However the alt will inherit the styles of the item the alt is on or what is inherited by its parent:

    <div style="background-color:black; height: 50px; width: 50px; color:white;">_x000D_
    <img src="ouch" alt="here i am"/>_x000D_
    <div>

In the above example, the alt text will be black. However with the color:white the alt text is white.

fast onliner for 'dictionary'-objects:

function isEmptyDict(d){for (var k in d) return false; return true}

The best source I have for this kind of question is this page: http://www.quirksmode.org/js/keys.html

What they say is that the key codes are odd on Safari, and consistent everywhere else (except that there's no keypress event on IE, but I believe keydown works).

To specify an application icon

1. In Solution Explorer, choose a project node (not the Solution node).
2. On the menu bar, choose Project, Properties.
3. When the Project Designer appears, choose the Application tab.
4. In the Icon list, choose an icon (.ico) file.

To specify an application icon and add it to your project

1. In Solution Explorer, choose a project node (not the Solution node).
2. On the menu bar, choose Project, Properties.
3. When the Project Designer appears, choose the Application tab.
4. Near the Icon list, choose the button, and then browse to the location of the icon file that you want.

The icon file is added to your project as a content file.

None of these answers solved my problem, which was that the items weren't the same width in my makeshift flexbox table when it was shrunk to a width too small.

The solution for me was simply to put overflow: hidden; on the flex-grow: 1; cells.

It seems to work when I replace the

Runtime.getRuntime().exec("rmiregistry 2020");

by

LocateRegistry.createRegistry(2020);

anyone an idea why? What's the difference?

According to my humble opinion and my work experience with git, staging area is not the same as index. I may be wrong of course, but as I said, my experience in using git and my logic tell me, that index is a structure that follows your changes to your working area(local repository) that are not excluded by ignoring settings and staging area is to keep files that are already confirmed to be committed, aka files in index on which add command was run on. You don't notice and realize that "slight" difference, because you use git commit -a -m "comment" adding indexed and cached files to stage area and committing in one command or using IDEs like IDEA for that too often. And cache is that what keeps changes in indexed files. If you want to remove file from index that has not been added to staging area before, options proposed before match for you, but... If you have done that already, you will need to use

Git restore --staged <file>

And, please, don't ask me where I was 10 years ago... I missed you, this answer is for further generations)

Most answer are assuming the RecyclerView uses a LinearLayoutManager, or GridLayoutManager, or even StaggeredGridLayoutManager, or assuming that the scrolling is vertical or horyzontal, but no one has posted a completly generic answer.

Using the ViewHolder's adapter is clearly not a good solution. An adapter might have more than 1 RecyclerView using it. It "adapts" their contents. It should be the RecyclerView (which is the one class which is responsible of what is currently displayed to the user, and not the adapter which is responsible only to provide content to the RecyclerView) which must notify your system that more items are needed (to load).

Here is my solution, using nothing else than the abstracted classes of the RecyclerView (RecycerView.LayoutManager and RecycerView.Adapter):

/**
 * Listener to callback when the last item of the adpater is visible to the user.
 * It should then be the time to load more items.
 **/
public abstract class LastItemListener extends RecyclerView.OnScrollListener {

    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
      super.onScrolled(recyclerView, dx, dy);

      // init
      RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();
      RecyclerView.Adapter adapter = recyclerView.getAdapter();

      if (layoutManager.getChildCount() > 0) {
        // Calculations..
        int indexOfLastItemViewVisible = layoutManager.getChildCount() -1;
        View lastItemViewVisible = layoutManager.getChildAt(indexOfLastItemViewVisible);
        int adapterPosition = layoutManager.getPosition(lastItemViewVisible);
        boolean isLastItemVisible = (adapterPosition == adapter.getItemCount() -1);

        // check
        if (isLastItemVisible)
          onLastItemVisible(); // callback
     }
   }

   /**
    * Here you should load more items because user is seeing the last item of the list.
    * Advice: you should add a bollean value to the class
    * so that the method {@link #onLastItemVisible()} will be triggered only once
    * and not every time the user touch the screen ;)
    **/
   public abstract void onLastItemVisible();

}


// --- Exemple of use ---

myRecyclerView.setOnScrollListener(new LastItemListener() {
    public void onLastItemVisible() {
         // start to load more items here.
    }
}

I've seen many answers but they seem confusing to me. Can't we just simply use Type Casting.

For ex:-

int s;
char i= '2';
s = (int) i;

There is no event raised when a class changes. The alternative is to manually raise an event when you programatically change the class:

$someElement.on('event', function() {
    $('#myDiv').addClass('submission-ok').trigger('classChange');
});

// in another js file, far, far away
$('#myDiv').on('classChange', function() {
     // do stuff
});

UPDATE

This question seems to be gathering some visitors, so here is an update with an approach which can be used without having to modify existing code using the new MutationObserver:

var $div = $("#foo");_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
  mutations.forEach(function(mutation) {_x000D_
    if (mutation.attributeName === "class") {_x000D_
      var attributeValue = $(mutation.target).prop(mutation.attributeName);_x000D_
      console.log("Class attribute changed to:", attributeValue);_x000D_
    }_x000D_
  });_x000D_
});_x000D_
observer.observe($div[0], {_x000D_
  attributes: true_x000D_
});_x000D_
_x000D_
$div.addClass('red');

.red { color: #C00; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="foo" class="bar">#foo.bar</div>

Be aware that the MutationObserver is only available for newer browsers, specifically Chrome 26, FF 14, IE 11, Opera 15 and Safari 6. See MDN for more details. If you need to support legacy browsers then you will need to use the method I outlined in my first example.

You can take advantage of the HTML prompt to unload mechanism, by specifying no unload handler:

window.onbeforeunload = null;
window.location.replace(URL);

See the notes section of the WindowEventHandlers.onbeforeunload for more information.

For quick and dirty:

year, month, day, hour, minute, second = xlrd.xldate_as_tuple(excelDate, wb.datemode)
whatYouWant = str(month)+'/'+str(day)+'/'+str(year)

You can use mkdir:

$ man 2 mkdir

#include <sys/stat.h>
#include <sys/types.h>

int result = mkdir("/home/me/test.txt", 0777);

You may want to use setArray method as mentioned in the javadoc below:

http://docs.oracle.com/javase/6/docs/api/java/sql/PreparedStatement.html#setArray(int, java.sql.Array)

Sample Code:

PreparedStatement pstmt = 
                conn.prepareStatement("select * from employee where id in (?)");
Array array = conn.createArrayOf("VARCHAR", new Object[]{"1", "2","3"});
pstmt.setArray(1, array);
ResultSet rs = pstmt.executeQuery();

Herb Sutter has an excellent article on string formatting. I recommend reading it. I've linked it before on SO.

What I do is put a config.php file in my root directory. This file is included by all PHP files in my project. In that config.php file, I then do the following;

define( 'ROOT_DIR', dirname(__FILE__) );

Then in all files, I know what the root of my project is and can do stuff like this

require_once( ROOT_DIR.'/include/functions.php' );

Sorry, no bonus points for getting outside of the public directory ;) This also has the unfortunate side affect that you still need a relative path for finding config.php, but it makes the rest of your includes much easier.

I found out it was:

$ git fetch upstream
$ git merge upstream/master

I forked the DividerItemDecoration from an older gist and simplified it to fit my use case, and I also modified it to draw the dividers the way they are drawn in ListView, including a divider after the last list item. This will also handle vertical ItemAnimator animations:

1) Add this class to your project:

public class DividerItemDecoration extends RecyclerView.ItemDecoration {
    private static final int[] ATTRS = new int[]{android.R.attr.listDivider};
    private Drawable divider;

    public DividerItemDecoration(Context context) {
        try {
            final TypedArray a = context.obtainStyledAttributes(ATTRS);
            divider = a.getDrawable(0);
            a.recycle();
        } catch (Resources.NotFoundException e) {
            // TODO Log or handle as necessary.
        }
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        super.getItemOffsets(outRect, view, parent, state);
        if (divider == null) return;
        if (parent.getChildAdapterPosition(view) < 1) return;

        if (getOrientation(parent) == LinearLayoutManager.VERTICAL)
            outRect.top = divider.getIntrinsicHeight();
        else
            throw new IllegalArgumentException("Only usable with vertical lists");
    }

    @Override
    public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) {
        if (divider == null) {
            super.onDrawOver(c, parent, state);
            return;
        }

        final int left = parent.getPaddingLeft();
        final int right = parent.getWidth() - parent.getPaddingRight();
        final int childCount = parent.getChildCount();

        for (int i = 0; i < childCount; ++i) {
            final View child = parent.getChildAt(i);
            final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
            final int size = divider.getIntrinsicHeight();
            final int top = (int) (child.getTop() - params.topMargin - size + child.getTranslationY());
            final int bottom = top + size;
            divider.setBounds(left, top, right, bottom);
            divider.draw(c);

            if (i == childCount - 1) {
                final int newTop = (int) (child.getBottom() + params.bottomMargin + child.getTranslationY());
                final int newBottom = newTop + size;
                divider.setBounds(left, newTop, right, newBottom);
                divider.draw(c);
            }
        }
    }

    private int getOrientation(RecyclerView parent) {
        if (!(parent.getLayoutManager() instanceof LinearLayoutManager))
            throw new IllegalStateException("Layout manager must be an instance of LinearLayoutManager");
        return ((LinearLayoutManager) parent.getLayoutManager()).getOrientation();
    }
}

2) Add the decorator to your RecylerView:

recyclerView.addItemDecoration(new DividerItemDecoration(getActivity()));
