The reason people do it (in my experience) is to differentiate between member variables and function parameters. In Java you can have a class like this:

public class TestClass {
  int var1;

  public void func1(int var1) {
     System.out.println("Which one is it?: " + var1);
  }
}

If you made the member variable _var1 or m_var1, you wouldn't have the ambiguity in the function.

So it's a style, and I wouldn't call it bad.

Use a testing framework

This might be helpful - http://seleniumhq.org/ - Selenium is a web application automated testing system.

You can create tests using the Firefox plugin Selenium IDE

Manual firing of events

To manually fire events the correct way you will need to use different methods for different browsers - either el.dispatchEvent or el.fireEvent where el will be your Anchor element. I believe both of these will require constructing an Event object to pass in.

The alternative, not entirely correct, quick-and-dirty way would be this:

var el = document.getElementById('anchorelementid');
el.onclick(); // Not entirely correct because your event handler will be called
              // without an Event object parameter.

Although building the URL or using tools is still possible, it is not needed anymore.

Can't figure out how to add to the code or reply to the message but here's support for jython that you can tack in before you give up:

# jython
try:
    from java.lang import Runtime
    runtime = Runtime.getRuntime()
    res = runtime.availableProcessors()
    if res > 0:
        return res
except ImportError:
    pass

This is so annoying.

Okay if anyone is still having issues or just doesn't want to add another library. All you have to do is place this middle ware line of code before your routes.

Cors Example

app.use((req, res, next) => {
    res.append('Access-Control-Allow-Origin', ['*']);
    res.append('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
    res.append('Access-Control-Allow-Headers', 'Content-Type');
    next();
});

// Express routes
app.get('/api/examples', (req, res)=> {...});

You can now do this in most "modern" browsers!

Here is the original article I read (posted July 10, 2010): HTML5: Changing the browser-URL without refreshing page.

For a more in-depth look into pushState/replaceState/popstate (aka the HTML5 History API) see the MDN docs.

TL;DR, you can do this:

window.history.pushState("object or string", "Title", "/new-url");

See my answer to Modify the URL without reloading the page for a basic how-to.

If you want to right-align in a form, you can try:

| Option | Description |
| ------:| -----------:|
| data   | path to data files to supply the data that will be passed into templates. |
| engine | engine to be used for processing templates. Handlebars is the default. |
| ext    | extension to be used for dest files. |

A file with associated buffering is called a stream and is declared to be a pointer to a defined type FILE. The fopen() function creates certain descriptive data for a stream and returns a pointer to designate the stream in all further transactions. Normally there are three open streams with constant pointers declared in the header and associated with the standard open files. At program startup three streams are predefined and need not be opened explicitly: standard input (for reading conventional input), standard output (for writing conventional output), and standard error (for writing diagnostic output). When opened the standard error stream is not fully buffered; the standard input and standard output streams are fully buffered if and only if the stream can be determined not to refer to an interactive device

My neat JavaScript trick is to separate the entire scenario into two different functions!

To prepare things, one global variable is declared and one event handler is defined:

  var tTimeout;
  element.addEventListener("transitionend", afterTransition, true);//firefox
  element.addEventListener("webkitTransitionEnd", afterTransition, true);//chrome

Then, when hiding element, I use something like this:

function hide(){
  element.style.opacity = 0;
}

function afterTransition(){
  element.style.display = 'none';
}

For reappearing the element, I am doing something like this:

function show(){
  element.style.display = 'block';
  tTimeout = setTimeout(timeoutShow, 100);
}

function timeoutShow(){
  element.style.opacity = 1;
}

It works, so far!

I ran into this issue working with pyspark. As this is a python frontend for code running on a jvm, it requires type safety and using float instead of int is not an option. I worked around the issue by wrapping the pandas pd.read_csv in a function that will fill user-defined columns with user-defined fill values before casting them to the required type. Here is what I ended up using:

def custom_read_csv(file_path, custom_dtype = None, fill_values = None, **kwargs):
    if custom_dtype is None:
        return pd.read_csv(file_path, **kwargs)
    else:
        assert 'dtype' not in kwargs.keys()
        df = pd.read_csv(file_path, dtype = {}, **kwargs)
        for col, typ in custom_dtype.items():
            if fill_values is None or col not in fill_values.keys():
                fill_val = -1
            else:
                fill_val = fill_values[col]
            df[col] = df[col].fillna(fill_val).astype(typ)
    return df

This answer only really works if you don't need to do anything other than transferring the inner code (innerHTML) from one to the other:

// Define old parent
var oldParent = document.getElementById('old-parent');

// Define new parent
var newParent = document.getElementById('new-parent');

// Basically takes the inner code of the old, and places it into the new one
newParent.innerHTML = oldParent.innerHTML;

// Delete / Clear the innerHTML / code of the old Parent
oldParent.innerHTML = '';

Hope this helps!

You can set the default props using the class name as shown below.

class Greeting extends React.Component {
  render() {
    return (
      <h1>Hello, {this.props.name}</h1>
    );
  }
}

// Specifies the default values for props:
Greeting.defaultProps = {
  name: 'Stranger'
};

You can use the React's recommended way from this link for more info

Here is a python3 method using str.translate and str.maketrans:

s = "abc&def#ghi"
print(s.translate(str.maketrans({'&': '\&', '#': '\#'})))

The printed string is abc\&def\#ghi.

According to Martin Fowler

The term was coined while Rebecca Parsons, Josh MacKenzie and I were preparing for a talk at a conference in September 2000. In the talk, we were pointing out the many benefits of encoding business logic into regular java objects rather than using Entity Beans. We wondered why people were so against using regular objects in their systems and concluded that it was because simple objects lacked a fancy name. So we gave them one, and it’s caught on very nicely.

Generally, a POJO is not bound to any restriction and any Java object can be called a POJO but there are some directions. A well-defined POJO should follow below directions.

1. Each variable in a POJO should be declared as private.
2. Default constructor should be overridden with public accessibility.
3. Each variable should have its Setter-Getter method with public accessibility.
4. Generally POJO should override equals(), hashCode() and toString() methods of Object (but it's not mandatory).
5. Overriding compare() method of Comparable interface used for sorting (Preferable but not mandatory).

And according to Java Language Specification, a POJO should not have to

1. Extend pre-specified classes
2. Implement pre-specified interfaces
3. Contain pre-specified annotations

However, developers and frameworks describe a POJO still requires the use prespecified annotations to implement features like persistence, declarative transaction management etc. So the idea is that if the object was a POJO before any annotations were added would return to POJO status if the annotations are removed then it can still be considered a POJO.

A JavaBean is a special kind of POJO that is Serializable, has a no-argument constructor, and allows access to properties using getter and setter methods that follow a simple naming convention.

Read more on Plain Old Java Object (POJO) Explained.

Do not forget that you also can pass these use variables by reference.

The use cases are when you need to change the use'd variable from inside of your callback (e.g. produce the new array of different objects from some source array of objects).

$sourcearray = [ (object) ['a' => 1], (object) ['a' => 2]];
$newarray = [];
array_walk($sourcearray, function ($item) use (&$newarray) {
    $newarray[] = (object) ['times2' => $item->a * 2];
});
var_dump($newarray);

Now $newarray will comprise (pseudocode here for brevity) [{times2:2},{times2:4}].

On the contrary, using $newarray with no & modifier would make outer $newarray variable be read-only accessible from within the closure scope. But $newarray within closure scope would be a completelly different newly created variable living only within the closure scope.

Despite both variables' names are the same these would be two different variables. The outer $newarray variable would comprise [] in this case after the code has finishes.

Your query should work for synonyms as well as the tables. However, you seem to expect indexes on views where there are not. Maybe is it materialized views ?

Sleep causes thread to suspend itself for x milliseconds while yield suspends the thread and immediately moves it to the ready queue (the queue which the CPU uses to run threads).

It seems that OpenQA, guys behind Selenium, have already addressed this problem. They defined some variables to explicitely match whitespaces. In my case, I need to use an XPATH similar to //td[text()="${nbsp}"].

I reproduced here the text from OpenQA concerning this issue (found here):

HTML automatically normalizes whitespace within elements, ignoring leading/trailing spaces and converting extra spaces, tabs and newlines into a single space. When Selenium reads text out of the page, it attempts to duplicate this behavior, so you can ignore all the tabs and newlines in your HTML and do assertions based on how the text looks in the browser when rendered. We do this by replacing all non-visible whitespace (including the non-breaking space " ") with a single space. All visible newlines (<br>, <p>, and <pre> formatted new lines) should be preserved.

We use the same normalization logic on the text of HTML Selenese test case tables. This has a number of advantages. First, you don't need to look at the HTML source of the page to figure out what your assertions should be; " " symbols are invisible to the end user, and so you shouldn't have to worry about them when writing Selenese tests. (You don't need to put " " markers in your test case to assertText on a field that contains " ".) You may also put extra newlines and spaces in your Selenese <td> tags; since we use the same normalization logic on the test case as we do on the text, we can ensure that assertions and the extracted text will match exactly.

This creates a bit of a problem on those rare occasions when you really want/need to insert extra whitespace in your test case. For example, you may need to type text in a field like this: "foo ". But if you simply write <td>foo </td> in your Selenese test case, we'll replace your extra spaces with just one space.

This problem has a simple workaround. We've defined a variable in Selenese, ${space}, whose value is a single space. You can use ${space} to insert a space that won't be automatically trimmed, like this: <td>foo${space}${space}${space}</td>. We've also included a variable ${nbsp}, that you can use to insert a non-breaking space.

Note that XPaths do not normalize whitespace the way we do. If you need to write an XPath like //div[text()="hello world"] but the HTML of the link is really "hello world", you'll need to insert a real " " into your Selenese test case to get it to match, like this: //div[text()="hello${nbsp}world"].

I got similar error after deleting a subproject, removed

"*compile project(path: ':MySubProject', configuration: 'android-endpoints')*"

in build.gradle (dependencies) under Gradle Scripts

I didn't see how to add parameters to the method call, it took me a while to find it, so I add it here. How to pass parameters in (to the javascript function), use "arguments[0]" as the parameter place and then set the parameter as input parameter in the executeScript function.

    driver.executeScript("function(arguments[0]);","parameter to send in");

os.path.abspath(os.path.join(somepath, '..'))

Observe:

import posixpath
import ntpath

print ntpath.abspath(ntpath.join('C:\\', '..'))
print ntpath.abspath(ntpath.join('C:\\foo', '..'))
print posixpath.abspath(posixpath.join('/', '..'))
print posixpath.abspath(posixpath.join('/home', '..'))

This method is easy to understand and works fine. The argument to the script ($1) is a reference (tag, hash, ...) to the commit starting from which you want to keep your history.

#!/bin/bash
git checkout --orphan temp $1 # create a new branch without parent history
git commit -m "Truncated history" # create a first commit on this branch
git rebase --onto temp $1 master # now rebase the part of master branch that we want to keep onto this branch
git branch -D temp # delete the temp branch

# The following 2 commands are optional - they keep your git repo in good shape.
git prune --progress # delete all the objects w/o references
git gc --aggressive # aggressively collect garbage; may take a lot of time on large repos

NOTE that old tags will still remain present; so you might need to remove them manually

remark: I know this is almost the same aswer as @yoyodin, but there are some important extra commands and informations here. I tried to edit the answer, but since it is a substantial change to @yoyodin's answer, my edit was rejected, so here's the information!

In Git 1.8.1 you can use the git symbolic-ref command with the "--short" option:

I hope this helps someone

I usually create a global function called is_empty() just to get around this issue

function is_empty($var)
{ 
 return empty($var);
}

Then anywhere I would normally have used empty() I just use is_empty()

select 
  * 
from sales 
where 
  dateadd(dd, datediff(dd, 0, salesDate), 0) = '11/11/2010'

I know this is an old thread, but there is a nice library to do this:

System Rules

Example from the docs:

public void MyTest {
    @Rule
    public final SystemOutRule systemOutRule = new SystemOutRule().enableLog();

    @Test
    public void overrideProperty() {
        System.out.print("hello world");
        assertEquals("hello world", systemOutRule.getLog());
    }
}

It will also allow you to trap System.exit(-1) and other things that a command line tool would need to be tested for.

Apart from using an escaped value as described in my other answer, it is also possible to fix this issue by enabling the Strict Math setting.

With strict math on, only maths that are inside unnecessary parentheses will be processed, so your code:

width: calc(100% - 200px);

Would work as expected with the strict math option enabled.

However, note that Strict Math is applied globally, not only inside calc(). That means, if you have:

font-size: 12px + 2px;

The math will no longer be processed by Less -- it will output font-size: 12px + 2px which is, obviously, invalid CSS. You'd have to wrap all maths that should be processed by Less in (previously unnecessary) parentheses:

font-size: (12px + 2px);

Strict Math is a nice option to consider when starting a new project, otherwise you'd possibly have to rewrite a good part of the code base. For the most common use cases, the escaped string approach described in the other answer is more suitable.

This link can help you: http://www.scriptol.com/html5/combobox.php

You have two examples. One in html4 and other in html5

HTML5

<input type="text" list="browsers"/>
 <datalist id="browsers">
    <option>Google</option>
    <option>IE9</option>
 </datalist>

HTML4

 <input type="text" id="theinput" name="theinput" />
 <select name="thelist" onChange="combo(this, 'theinput')">
   <option>one</option>
   <option>two</option>
   <option>three</option>
 </select>

 function combo(thelist, theinput) {
     theinput = document.getElementById(theinput);
     var idx = thelist.selectedIndex;
     var content = thelist.options[idx].innerHTML;
     theinput.value = content;
 }

This should work!

[HttpPost]
public ActionResult RedirectToImages(int id)
{
    return RedirectToAction("Index", "ProductImageManeger", new  { id = id });
}

[HttpGet]
public ViewResult Index(int id)
{
    return View(_db.ProductImages.Where(rs => rs.ProductId == id).ToList());
}

Notice that you don't have to pass the name of view if you are returning the same view as implemented by the action.

Your view should inherit the model as this:

@model <Your class name>

You can then access your model in view as:

@Model.<property_name>

for i in range(11):
    string = "string{0}".format(i)

What you did (range[1,10]) is

• a TypeError since brackets denote an index (a[3]) or a slice (a[3:5]) of a list,
• a SyntaxError since [1,10] is invalid, and
• a double off-by-one error since range(1,10) is [1, 2, 3, 4, 5, 6, 7, 8, 9], and you seem to want [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

And string = "string" + i is a TypeError since you can't add an integer to a string (unlike JavaScript).

Look at the documentation for Python's new string formatting method, it is very powerful.

I use the following format and works well.

robocopy \\SourceServer\Path \\TargetServer\Path filename.txt

to copy everything you can replace filename.txt with *.* and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html

If for whatever reason you wanted to do it manually (without using a module like csv,pandas,numpy etc.):

with open('myfile.csv','w') as f:
    for sublist in mylist:
        for item in sublist:
            f.write(item + ',')
        f.write('\n')

Of course, rolling your own version can be error-prone and inefficient ... that's usually why there's a module for that. But sometimes writing your own can help you understand how they work, and sometimes it's just easier.

If you try a lot of these answers out on different resolutions, computers with multiple monitors, etc. you may find that they don't work reliably. This is because you need to use a transform to get the mouse position relative to the current screen, not the entire viewing area which consists of all your monitors. Something like this...(where "this" is a WPF window).

var transform = PresentationSource.FromVisual(this).CompositionTarget.TransformFromDevice;
var mouse = transform.Transform(GetMousePosition());

public System.Windows.Point GetMousePosition()
{
    var point = Forms.Control.MousePosition;
    return new Point(point.X, point.Y);
}

The one way found is to use the geoXML3 library which is suitable for usage along with KML processor Version 3 of the Google Maps JavaScript API.

1. Performance:

Assume your where clause is like this:

WHERE NAME='JON'

If the NAME column is of any type other than nvarchar or nchar, then you should not specify the N prefix. However, if the NAME column is of type nvarchar or nchar, then if you do not specify the N prefix, then 'JON' is treated as non-unicode. This means the data type of NAME column and string 'JON' are different and so SQL Server implicitly converts one operand’s type to the other. If the SQL Server converts the literal’s type to the column’s type then there is no issue, but if it does the other way then performance will get hurt because the column's index (if available) wont be used.

2. Character set:

If the column is of type nvarchar or nchar, then always use the prefix N while specifying the character string in the WHERE criteria/UPDATE/INSERT clause. If you do not do this and one of the characters in your string is unicode (like international characters - example - a) then it will fail or suffer data corruption.

Move your code from ngAfterViewInit to ngAfterContentInit

Take a look at that : http://davidwalsh.name/detect-android

JavaScript:

var ua = navigator.userAgent.toLowerCase();
var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile");
if(isAndroid) {
  // Do something!
  // Redirect to Android-site?
  window.location = 'http://android.davidwalsh.name';
}

PHP:

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if(stripos($ua,'android') !== false) { // && stripos($ua,'mobile') !== false) {
  header('Location: http://android.davidwalsh.name');
  exit();
}

Edit : As pointed out in some comments, this will work in 99% of the cases, but some edge cases are not covered. If you need a much more advanced and bulletproofed solution in JS, you should use platform.js : https://github.com/bestiejs/platform.js

def f(dic):
    if 'a' in dic:
        print dic['a'],
        pass
    else: print 'None',

    if 'b' in dic:
        print dic['b'],
        pass
    else: print 'None',

    if 'c' in dic:
        print dic['c'],
        pass
    else: print 'None',
    print
    pass
f({})
f({'a':20,
   'c':30})
f({'a':20,
   'c':30,
   'b':'red'})
____________

the above code will output

None None None
20 None 30
20 red 30

This is as good as passing variable arguments by means of a dictionary

// Simplest way

$('select').change(function() {
    $('select').html(originalContent); //Restore Original Content
    $('select option[myfilter=1]').remove(); // Filter my options
});

I had a slightly more specialised case, a search form which had an input which had autocomplete for a person name. The Javascript code set a hidden input which from.reset() does not clear.

However I didn't want to reset all hidden inputs. There I added a class, search-value, to the hidden inputs which where to be cleared.

$('form#search-form').reset();
$('form#search-form input[type=hidden].search-value').val('');

**Set proper alias name**
CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509","BC");
            X509Certificate cert = (X509Certificate) certificateFactory.generateCertificate(derInputStream);
            String alias = cert.getSubjectX500Principal().getName();
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
            trustStore.load(null);
trustStore.setCertificateEntry(alias, cert);

As long as your file has consistent formatting (i.e. line-breaks), this is easy with just basic file IO and string operations:

with open('my_file.txt', 'rU') as in_file:
    data = in_file.read().split('\n')

That will store your data file as a list of items, one per line. To then put it into a file, you would do the opposite:

with open('new_file.txt', 'w') as out_file:
    out_file.write('\n'.join(data)) # This will create a string with all of the items in data separated by new-line characters

Hopefully that fits what you're looking for.

The String class provides valueOf methods for all primitive types and Object type so I assume they are convenience methods that can all be accessed through the one class.

I've used the "slugify" method from underscore.string and it worked like a charm:

https://github.com/epeli/underscore.string#slugifystring--string

The cool thing is that you can really just import this method, don't need to import the entire library.

A really simple approach:

class CustomError(Exception):
    pass

raise CustomError("Hmm, seems like this was custom coded...")

Or, have the error raise without printing __main__ (may look cleaner and neater):

class CustomError(Exception):
    __module__ = Exception.__module__

raise CustomError("Improved CustomError!")

THIS_DIR := $(dir $(abspath $(firstword $(MAKEFILE_LIST))))

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

In PHP DateTime (PHP >= 5.3)

$dt = new DateTime();
$dt->setTimezone(new DateTimeZone('UTC'));
echo $dt->getTimestamp();

I liked JonBrave's answer but I have messy enough working directories that commit -a scares me a bit, so here's what I've done:

git config --global alias.exclude-ignored '!git ls-files -z --ignored --exclude-standard | xargs -0 git rm -r --cached && git ls-files -z --ignored --exclude-standard | xargs -0 git stage && git stage .gitignore && git commit -m "new gitignore and remove ignored files from index"'

breaking it down:

git ls-files -z --ignored --exclude-standard | xargs -0 git rm -r --cached 
git ls-files -z --ignored --exclude-standard | xargs -0 git stage 
git stage .gitignore 
git commit -m "new gitignore and remove ignored files from index"

• remove ignored files from index
• stage .gitignore and the files you just removed
• commit

You want this:

function validate() {
    var acc = document.getElementsByName('acc')[0].value;
    var pass = document.getElementsByName('pass')[0].value;

    alert (acc);
}

take a look at xp_sprintf. example below.

DECLARE @ret_string varchar (255)
EXEC xp_sprintf @ret_string OUTPUT, 
    'INSERT INTO %s VALUES (%s, %s)', 'table1', '1', '2'
PRINT @ret_string

Result looks like this:

INSERT INTO table1 VALUES (1, 2)

Just found an issue with the max size (255 char limit) of the string with this so there is an alternative function you can use:

create function dbo.fnSprintf (@s varchar(MAX), 
                @params varchar(MAX), @separator char(1) = ',')
returns varchar(MAX)
as
begin
declare @p varchar(MAX)
declare @paramlen int

set @params = @params + @separator
set @paramlen = len(@params)
while not @params = ''
begin
    set @p = left(@params+@separator, charindex(@separator, @params)-1)
    set @s = STUFF(@s, charindex('%s', @s), 2, @p)
    set @params = substring(@params, len(@p)+2, @paramlen)
end
return @s
end

To get the same result as above you call the function as follows:

print dbo.fnSprintf('INSERT INTO %s VALUES (%s, %s)', 'table1,1,2', default)

Quick Description of AJAX

AJAX is simply Asyncronous JSON or XML (in most newer situations JSON). Because we are doing an ASYNC task we will likely be providing our users with a more enjoyable UI experience. In this specific case we are doing a FORM submission using AJAX.

Really quickly there are 4 general web actions GET, POST, PUT, and DELETE; these directly correspond with SELECT/Retreiving DATA, INSERTING DATA, UPDATING/UPSERTING DATA, and DELETING DATA. A default HTML/ASP.Net webform/PHP/Python or any other form action is to "submit" which is a POST action. Because of this the below will all describe doing a POST. Sometimes however with http you might want a different action and would likely want to utilitize .ajax.

My code specifically for you (described in code comments):

/* attach a submit handler to the form */
$("#formoid").submit(function(event) {

  /* stop form from submitting normally */
  event.preventDefault();

  /* get the action attribute from the <form action=""> element */
  var $form = $(this),
    url = $form.attr('action');

  /* Send the data using post with element id name and name2*/
  var posting = $.post(url, {
    name: $('#name').val(),
    name2: $('#name2').val()
  });

  /* Alerts the results */
  posting.done(function(data) {
    $('#result').text('success');
  });
  posting.fail(function() {
    $('#result').text('failed');
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<form id="formoid" action="studentFormInsert.php" title="" method="post">
  <div>
    <label class="title">First Name</label>
    <input type="text" id="name" name="name">
  </div>
  <div>
    <label class="title">Last Name</label>
    <input type="text" id="name2" name="name2">
  </div>
  <div>
    <input type="submit" id="submitButton" name="submitButton" value="Submit">
  </div>
</form>

<div id="result"></div>

Documentation

From jQuery website $.post documentation.

Example: Send form data using ajax requests

$.post("test.php", $("#testform").serialize());

Example: Post a form using ajax and put results in a div

<!DOCTYPE html>
<html>
    <head>
        <script src="http://code.jquery.com/jquery-1.9.1.js"></script>

            <input type="submit" value="Search" />
        </form>
        <!-- the result of the search will be rendered inside this div -->
        <div id="result"></div>
        <script>
            /* attach a submit handler to the form */
            $("#searchForm").submit(function(event) {

                /* stop form from submitting normally */
                event.preventDefault();

                /* get some values from elements on the page: */
                var $form = $(this),
                    term = $form.find('input[name="s"]').val(),
                    url = $form.attr('action');

                /* Send the data using post */
                var posting = $.post(url, {
                    s: term
                });

                /* Put the results in a div */
                posting.done(function(data) {
                    var content = $(data).find('#content');
                    $("#result").empty().append(content);
                });
            });
        </script>
    </body>
</html>

I faced the same problem and did the filtering false like below working for me. You can try the same...

<testResources>
    <testResource>
        <directory>src/test/java</directory>
        <filtering>false</filtering>
    </testResource>
    <testResource>
        <directory>src/test/resources</directory>
        <filtering>false</filtering>
    </testResource>
</testResources>

You just put them in __init__.py.

So with test/classes.py being:

class A(object): pass
class B(object): pass

... and test/__init__.py being:

from classes import *

class Helper(object): pass

You can import test and have access to A, B and Helper

>>> import test
>>> test.A
<class 'test.classes.A'>
>>> test.B
<class 'test.classes.B'>
>>> test.Helper
<class 'test.Helper'>

Use Python 2.7, is has more 3rd party libs at the moment. (Edit: see below).

I recommend you using the stdlib module urllib2, it will allow you to comfortably get web resources. Example:

import urllib2

response = urllib2.urlopen("http://google.de")
page_source = response.read()

For parsing the code, have a look at BeautifulSoup.

BTW: what exactly do you want to do:

Just for background, I need to download a page and replace any img with ones I have

Edit: It's 2014 now, most of the important libraries have been ported, and you should definitely use Python 3 if you can. python-requests is a very nice high-level library which is easier to use than urllib2.

It really doesn't matter.
If you feed .c to a c++ compiler it will compile as cpp, .cc/.cxx is just an alternative to .cpp used by some compilers.

.hpp is an attempt to distinguish header files where there are significant c and c++ differences. A common usage is for the .hpp to have the necessary cpp wrappers or namespace and then include the .h in order to expose a c library to both c and c++.

If your goal is to find CSS selectors you can use MRI (once MRI is open, click any element to see various selectors for the element):

Surprising to see nobody mentioned document.hasFocus

if (document.hasFocus()) console.log('Tab is active')

if u cant use " export " cmd
then Just use:

setenv path /dir

like this

setenv ORACLE_HOME /data/u01/apps/oracle/11.2.0.3.0

Very old question, but just had to build this for an app today and found the settings shown in other answers do not result in a clean image (possibly as new options were added in later .Net versions).

Assuming you want the text in the centre of the bitmap, you can do this:

// Load the original image
Bitmap bmp = new Bitmap("filename.bmp");

// Create a rectangle for the entire bitmap
RectangleF rectf = new RectangleF(0, 0, bmp.Width, bmp.Height);

// Create graphic object that will draw onto the bitmap
Graphics g = Graphics.FromImage(bmp);

// ------------------------------------------
// Ensure the best possible quality rendering
// ------------------------------------------
// The smoothing mode specifies whether lines, curves, and the edges of filled areas use smoothing (also called antialiasing). 
// One exception is that path gradient brushes do not obey the smoothing mode. 
// Areas filled using a PathGradientBrush are rendered the same way (aliased) regardless of the SmoothingMode property.
g.SmoothingMode = SmoothingMode.AntiAlias;

// The interpolation mode determines how intermediate values between two endpoints are calculated.
g.InterpolationMode = InterpolationMode.HighQualityBicubic;

// Use this property to specify either higher quality, slower rendering, or lower quality, faster rendering of the contents of this Graphics object.
g.PixelOffsetMode = PixelOffsetMode.HighQuality;

// This one is important
g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;

// Create string formatting options (used for alignment)
StringFormat format = new StringFormat()
{
    Alignment = StringAlignment.Center,
    LineAlignment = StringAlignment.Center
};

// Draw the text onto the image
g.DrawString("yourText", new Font("Tahoma",8), Brushes.Black, rectf, format);

// Flush all graphics changes to the bitmap
g.Flush();

// Now save or use the bitmap
image.Image = bmp;

I think the officially preferred way is now to use Less, and either dynamically override the bootstrap.css (using less.js), or recompile bootstrap.css (using Node or the Less compiler).

From the Bootstrap docs, here's how to override bootstrap.css styles dynamically:

Download the latest Less.js and include the path to it (and Bootstrap) in the <head>.

 <link rel="stylesheet/less" href="/path/to/bootstrap.less">
    <script src="/path/to/less.js"></script>

To recompile the .less files, just save them and reload your page. Less.js compiles them and stores them in local storage.

Or if you prefer to statically compile a new bootstrap.css with your custom styles (for production environments):

Install the LESS command line tool via Node and run the following command:

$ lessc ./less/bootstrap.less > bootstrap.css

In special cases where you want to find whether a word is contained in a long text, you can iterate through the long text with a loop.

found=F
query_word=this
long_string="many many words in this text"
for w in $long_string; do
    if [ "$w" = "$query_word" ]; then
          found=T
          break
    fi
done

This is pure Bourne shell.

class Foo          (object):
    # ^class name  #^ inherits from object

    bar = "Bar" #Class attribute.

    def __init__(self):
        #        #^ The first variable is the class instance in methods.  
        #        #  This is called "self" by convention, but could be any name you want.
        #^ double underscore (dunder) methods are usually special.  This one 
        #  gets called immediately after a new instance is created.

        self.variable = "Foo" #instance attribute.
        print self.variable, self.bar  #<---self.bar references class attribute
        self.bar = " Bar is now Baz"   #<---self.bar is now an instance attribute
        print self.variable, self.bar  

    def method(self, arg1, arg2):
        #This method has arguments.  You would call it like this:  instance.method(1, 2)
        print "in method (args):", arg1, arg2
        print "in method (attributes):", self.variable, self.bar


a = Foo() # this calls __init__ (indirectly), output:
                 # Foo bar
                 # Foo  Bar is now Baz
print a.variable # Foo
a.variable = "bar"
a.method(1, 2) # output:
               # in method (args): 1 2
               # in method (attributes): bar  Bar is now Baz
Foo.method(a, 1, 2) #<--- Same as a.method(1, 2).  This makes it a little more explicit what the argument "self" actually is.

class Bar(object):
    def __init__(self, arg):
        self.arg = arg
        self.Foo = Foo()

b = Bar(a)
b.arg.variable = "something"
print a.variable # something
print b.Foo.variable # Foo

You can have a look at AngularStrap, the navbar directive seems to be what you are looking for:

https://github.com/mgcrea/angular-strap/blob/master/src/navbar/navbar.js

.directive('bsNavbar', function($location) {
  'use strict';

  return {
    restrict: 'A',
    link: function postLink(scope, element, attrs, controller) {
      // Watch for the $location
      scope.$watch(function() {
        return $location.path();
      }, function(newValue, oldValue) {

        $('li[data-match-route]', element).each(function(k, li) {
          var $li = angular.element(li),
            // data('match-rout') does not work with dynamic attributes
            pattern = $li.attr('data-match-route'),
            regexp = new RegExp('^' + pattern + '$', ['i']);

          if(regexp.test(newValue)) {
            $li.addClass('active');
          } else {
            $li.removeClass('active');
          }

        });
      });
    }
  };
});

To use this directive:

1. Download AngularStrap from http://mgcrea.github.io/angular-strap/

2. Include the script on your page after bootstrap.js:
   <script src="lib/angular-strap.js"></script>

3. Add the directives to your module:
   angular.module('myApp', ['$strap.directives'])

4. Add the directive to your navbar:
   <div class="navbar" bs-navbar>

5. Add regexes on each nav item:
   <li data-match-route="/about"><a href="#/about">About</a></li>

In your entity definition, you're not specifying the @JoinColumn for the Account joined to a Transaction. You'll want something like this:

@Entity
public class Transaction {
    @ManyToOne(cascade = {CascadeType.ALL},fetch= FetchType.EAGER)
    @JoinColumn(name = "accountId", referencedColumnName = "id")
    private Account fromAccount;
}

EDIT: Well, I guess that would be useful if you were using the @Table annotation on your class. Heh. :)

    import torch.nn as nn        

    # a simple network
    rand_net = nn.Sequential(nn.Linear(in_features, h_size),
                             nn.BatchNorm1d(h_size),
                             nn.ReLU(),
                             nn.Linear(h_size, h_size),
                             nn.BatchNorm1d(h_size),
                             nn.ReLU(),
                             nn.Linear(h_size, 1),
                             nn.ReLU())

    # initialization function, first checks the module type,
    # then applies the desired changes to the weights
    def init_normal(m):
        if type(m) == nn.Linear:
            nn.init.uniform_(m.weight)

    # use the modules apply function to recursively apply the initialization
    rand_net.apply(init_normal)

A COUNT query is faster, although maybe not noticeably, but as far as getting the desired result, both should be sufficient.

I edited ralf's htp code so that it would compile (on gcc, running ubuntu 16.04 lts). It was just a matter of initializing the variables.

In order to remove all the spaces from the beginning and the end of a string (including end of line characters):

echo $variable | xargs echo -n

This will remove duplicate spaces also:

echo "  this string has a lot       of spaces " | xargs echo -n

Produces: 'this string has a lot of spaces'

Change *.cs to .cs in the excludefileslist.txt

netstat -ano | findstr :PORT

... but it is in fact a bit weak and I personnaly don't use it anymore. I switched to GIMP and it is indeed pretty good.

The answer from mobius is not wrong but in some cases you must use imagemaps even if it seems a bit old and rusty. For instance, in a newsletter, where you can't use HTML/CSS to do what you want.

I managed to allow all my requisite sites with this header:

header("Content-Security-Policy: default-src *; style-src 'self' 'unsafe-inline'; font-src 'self' data:; script-src 'self' 'unsafe-inline' 'unsafe-eval' stackexchange.com");                    

I used some of the answers and found one that fit my case ( make sure all tasks are in the release branch).

Other methods works as well but I found that they might add lines that I do not need, like merge commits that add no value.

git fetch
git log origin/master..origin/release-1.1 --oneline --no-merges

or you can compare your current with master

git fetch
git log origin/master..HEAD --oneline --no-merges

git fetch is there to make sure you are using updated info.

In this way each commit will be on a line and you can copy/paste that into an text editor and start comparing the tasks with the commits that will be merged.

Make the method type [HttpPost], create a model that has one int[] parameter, and post with json:

/* Model */
public class CategoryRequestModel 
{
    public int[] Categories { get; set; }
}

/* WebApi */
[HttpPost]
public HttpResponseMessage GetCategories(CategoryRequestModel model)
{
    HttpResponseMessage resp = null;

    try
    {
        var categories = //your code to get categories

        resp = Request.CreateResponse(HttpStatusCode.OK, categories);

    }
    catch(Exception ex)
    {
        resp = Request.CreateErrorResponse(HttpStatusCode.InternalServerError, ex);
    }

    return resp;
}

/* jQuery */
var ajaxSettings = {
    type: 'POST',
    url: '/Categories',
    data: JSON.serialize({Categories: [1,2,3,4]}),
    contentType: 'application/json',
    success: function(data, textStatus, jqXHR)
    {
        //get categories from data
    }
};

$.ajax(ajaxSettings);

The easiest solution to animate the DOM elements is using CSS transitions/animations but I think you already know that and you try to use canvas to do stuff CSS doesn't let you to do. What about CSS custom filters? you can transform your elements in any imaginable way if you know how to write shaders. Some other link and don't forget to check the CSS filter lab.
Note: As you can probably imagine browser support is bad.

Probably my solution will suit for a lot of users, I hope so.

What I am suggesting it is making TextView with your style. It works for me perfectly, and has got all features, like a button.

First of all lets make button style, which you can use everywhere...I am creating button_with_hover.xml

    <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" >
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#8dbab3" />
            <gradient android:angle="-90" android:startColor="#48608F" android:endColor="#48608F"  />
        </shape>

        <!--#284682;-->
        <!--border-color: #223b6f;-->
    </item>
    <item android:state_focused="true">
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#284682" />
            <solid android:color="#284682"/>
        </shape>
    </item>
    <item >
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="@color/ControlColors" />
            <gradient android:angle="-90" android:startColor="@color/ControlColors" android:endColor="@color/ControlColors" />
        </shape>
    </item>

</selector>

Secondly, Lets create a textview button.

    <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="20dip"
    android:layout_gravity="right|bottom"
    android:gravity="center"
    android:padding="12dip"
    android:background="@drawable/button_with_hover"
    android:clickable="true"
    android:drawableLeft="@android:drawable/btn_star_big_off"
    android:textColor="#ffffffff"
    android:text="Golden Gate" />

And this is a result. Then style your custom button with any colors or any other properties and margins. Good luck

I'm surprised no-one has mentioned this - since 2013, python itself is capable of installing pip, no external commands (and no internet connection) required.

sudo -H python -m ensurepip

This will create a similar install to what easy_install would.

Since Android is open source, you don't actually need to reimplement ListView's optimizations. You can grab ListView's code and try to find a way to hack in the animation, you can also open a feature request in android bug tracker (and if you decided to implement it, don't forget to contribute a patch).

FYI, the ListView source code is here.

This work perfectly for me:

To call a PHP function (with parameters too) you can, like a lot of people said, send a parameter opening the PHP file and from there check the value of the parameter to call the function. But you can also do that lot of people say it's impossible: directly call the proper PHP function, without adding code to the PHP file.

I found a way:

This for JavaScript:

function callPHP(expression, objs, afterHandler) {
        expression = expression.trim();
        var si = expression.indexOf("(");
        if (si == -1)
            expression += "()";
        else if (Object.keys(objs).length > 0) {
            var sfrom = expression.substring(si + 1);
            var se = sfrom.indexOf(")");
            var result = sfrom.substring(0, se).trim();
            if (result.length > 0) {
                var params = result.split(",");
                var theend = expression.substring(expression.length - sfrom.length + se);
                expression = expression.substring(0, si + 1);
                for (var i = 0; i < params.length; i++) {
                    var param = params[i].trim();
                    if (param in objs) {
                        var value = objs[param];
                        if (typeof value == "string")
                            value = "'" + value + "'";
                        if (typeof value != "undefined")
                            expression += value + ",";
                    }
                }
                expression = expression.substring(0, expression.length - 1) + theend;
            }
        }
        var doc = document.location;
        var phpFile = "URL of your PHP file";
        var php =
            "$docl = str_replace('/', '\\\\', '" + doc + "'); $absUrl = str_replace($docl, $_SERVER['DOCUMENT_ROOT'], str_replace('/', '\\\\', '" + phpFile + "'));" +
            "$fileName = basename($absUrl);$folder = substr($absUrl, 0, strlen($absUrl) - strlen($fileName));" +
            "set_include_path($folder);include $fileName;" + expression + ";";
        var url = doc + "/phpCompiler.php" + "?code=" + encodeURIComponent(php);
        $.ajax({
            type: 'GET',
            url: url,
            complete: function(resp){
                var response = resp.responseText;
                afterHandler(response);
            }
        });
    }

This for a PHP file which isn't your PHP file, but another, which path is written in url variable of JS function callPHP , and it's required to evaluate PHP code. This file is called 'phpCompiler.php' and it's in the root directory of your website:

<?php
$code = urldecode($_REQUEST['code']);
$lines = explode(";", $code);
foreach($lines as $line)
    eval(trim($line, " ") . ";");
?>

So, your PHP code remain equals except return values, which will be echoed:

<?php
function add($a,$b){
  $c=$a+$b;
  echo $c;
}
function mult($a,$b){
  $c=$a*$b;
  echo $c;
}

function divide($a,$b){
  $c=$a/$b;
  echo $c;
}
?>

I suggest you to remember that jQuery is required:
Download it from Google CDN:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

or from Microsoft CDN: "I prefer Google! :)"

<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.1.min.js"></script>

Better is to download the file from one of two CDNs and put it as local file, so the startup loading of your website's faster!

The choice is to you!

//Names of parameters are custom, they haven't to be equals of these of the PHP file.
//These fake names are required to assign value to the parameters in PHP
//using an hash table.
callPHP("add(num1, num2)", {
            'num1' : 1,
            'num2' : 2
        },
            function(output) {
                alert(output); //This to display the output of the PHP file.
        });

I had the same problem in Android Studio 1.2.1.1. It was just liske the other answers said, however, I was not able to find where to add the dependencies. Finally I found it under File->Project structure->Dependencies This menu will give you the option at add the dependency to the Google Play Services library.

If you are using more animation attributes the shorthand is:

animation: bubble 2s linear 0.5s 1 normal forwards;

This gives:

• bubble animation name
• 2s duration
• linear timing-function
• 0.5s delay
• 1 iteration-count (can be 'infinite')
• normal direction
• forwards fill-mode (set 'backwards' if you want to have compatibility to use the end position as the final state[this is to support browsers that has animations turned off]{and to answer only the title, and not your specific case})

If the culture of the result doesn't matters or we're only talking of integer values, CONVERT or CAST will be fine.

However, if the result must match a specific culture, FORMAT might be the function to go:

DECLARE @value DECIMAL(19,4) = 1505.5698
SELECT CONVERT(NVARCHAR, @value)        -->  1505.5698
SELECT FORMAT(@value, 'N2', 'en-us')    --> 1,505.57
SELECT FORMAT(@value, 'N2', 'de-de')    --> 1.505,57

For more information on FORMAT see here.

Of course, formatting the result should be a matter of the UI layer of the software.

Okay, let's understand the difference between active and passive code.

The active code is the implementation of functions, procedures, methods, i.e. the pieces of code that should be compiled to executable machine code. We store it in .c files and sure we need to compile it.

The passive code is not being execute itself, but it needed to explain the different modules how to communicate with each other. Usually, .h files contains only prototypes (function headers), structures.

An exception are macros, that formally can contain an active pieces, but you should understand that they are using at the very early stage of building (preprocessing) with simple substitution. At the compile time macros already are substituted to your .c file.

Another exception are C++ templates, that should be implemented in .h files. But here is the story similar to macros: they are substituted on the early stage (instantiation) and formally, each other instantiation is another type.

In conclusion, I think, if the modules formed properly, we should never compile the header files.

list(cursor) works because a cursor is an iterable; you can also use cursor in a loop:

for row in cursor:
    # ...

A good database adapter implementation will fetch rows in batches from the server, saving on the memory footprint required as it will not need to hold the full result set in memory. cursor.fetchall() has to return the full list instead.

There is little point in using list(cursor) over cursor.fetchall(); the end effect is then indeed the same, but you wasted an opportunity to stream results instead.

Try this code:

<input type="text" name="Phone Number" pattern="[7-9]{1}[0-9]{9}" 
       title="Phone number with 7-9 and remaing 9 digit with 0-9">

This code will inputs only in the following format:

9238726384 (starting with 9 or 8 or 7 and other 9 digit using any number)
8237373746
7383673874

Incorrect format:
2937389471(starting not with 9 or 8 or 7)
32796432796(more than 10 digit)
921543(less than 10 digit)

Laravel 5 uses .env file to configure your app. .env should not be committed on your repository, like github or bitbucket. On your local environment your .env will look like the following:

# .env
APP_ENV=local

For your production server, you might have the following config:

# .env
APP_ENV=production

You could use

IFNULL(email, '') > ''

In your component's template you can use multiple arguments by separating them with colons:

{{ myData | myPipe: 'arg1':'arg2':'arg3'... }}

From your code it will look like this:

new MyPipe().transform(myData, arg1, arg2, arg3)

And in your transform function inside your pipe you can use the arguments like this:

export class MyPipe implements PipeTransform { 
    // specify every argument individually   
    transform(value: any, arg1: any, arg2: any, arg3: any): any { }
    // or use a rest parameter
    transform(value: any, ...args: any[]): any { }
}

Beta 16 and before (2016-04-26)

Pipes take an array that contains all arguments, so you need to call them like this:

new MyPipe().transform(myData, [arg1, arg2, arg3...])

And your transform function will look like this:

export class MyPipe implements PipeTransform {    
    transform(value:any, args:any[]):any {
        var arg1 = args[0];
        var arg2 = args[1];
        ...
    }
}

Tornado is designed for long-polling, and includes a very minimal (few hundred lines of Python) chat app in /examples/chatdemo , including server code and JS client code. It works like this:

• Clients use JS to ask for an updates since (number of last message), server URLHandler receives these and adds a callback to respond to the client to a queue.

• When the server gets a new message, the onmessage event fires, loops through the callbacks, and sends the messages.

• The client-side JS receives the message, adds it to the page, then asks for updates since this new message ID.

You don't have to use hidden field. Use "title" property. It will show browser default tooltip. You can then use jQuery plugin (like before mentioned bootstrap tooltip) to show custom formatted tooltip.

<label for="male" title="Hello This Will Have Some Value">Hello ...</label>

Hint: you can also use css to trim text, that does not fit into the box (text-overflow property). See http://jsfiddle.net/8eeHs/

There is a nifty plugin built from yonran that can do the detection. Here is his previously answered question on StackOverflow. It works for most of the browsers. Application is as simple as this:

window.onresize = function onresize() {
  var r = DetectZoom.ratios();
  zoomLevel.innerHTML =
    "Zoom level: " + r.zoom +
    (r.zoom !== r.devicePxPerCssPx
        ? "; device to CSS pixel ratio: " + r.devicePxPerCssPx
        : "");
}

All you need to do is to change the PATH variable to include the bin directory of your PostgreSQL installation.

An explanation on how to change environment variables is here:

http://support.microsoft.com/kb/310519
http://www.computerhope.com/issues/ch000549.htm

To verify that the path is set correctly, you can use:

echo %PATH%

on the commandline.

Colon does not have special meaning in a character class and does not need to be escaped. According to the PHP regex docs, the only characters that need to be escaped in a character class are the following:

All non-alphanumeric characters other than \, -, ^ (at the start) and the terminating ] are non-special in character classes, but it does no harm if they are escaped.

For more info about Java regular expressions, see the docs.

  alert(currentAnchor.attr('href'));

I know this thread is old, but still answering it so that no-one else should spend sleepless nights.

I was refactoring an old project, whose layout files all contained hardcoded attributes such as android:maxLength = 500. So I decided to register it in my res/dimen file as <dimen name="max_length">500</dimen>.

Finished refactoring almost 30 layout files with my res-value. Guess what? the next time I ran my project it started throwing the same InflateException.

As a solution, needed to redo my all changes and keep all-those values as same as before.

TLDR;

step 1: All running good.

step 2: To boost my maintenance I replaced android:maxLength = 500 with <dimen name="max_length">500</dimen> and android:maxLength = @dimen/max_length , that's where it all went wrong(crashing with InflateException).

step 3: All running bad

step 4: Re-do all my work by again replacing android:maxLength = @dimen/max_length with android:maxLength = 500.Everything got fixed.

step 5: All running good.

bootstrap.min.css is more specific than your own stylesheet if you just use .table td. So use this instead:

.table>tbody>tr>th, .table>tbody>tr>td {
    border-top: none;
}

On Windows, line.separator is a CR/LF combination (reference here).

The Java String.split() method takes a regular expression. So I think there's some confusion here.

To do this you need a JDBC Connection and/or driver that supports logging the sql at a low level.

Take a look at log4jdbc

 #alertlist li:hover:after,#alertlist li.selected:after
{
    position:absolute;
    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}?

Java is typically installed in /usr/java locate the version you have and then do the following:

Assuming you are using bash (if you are just starting off, i recommend bash over other shells) you can simply type in bash to start it.

Edit your ~/.bashrc file and add the paths as follows:

for eg. vi ~/.bashrc

insert following lines:

export JAVA_HOME=/usr/java/<your version of java>
export PATH=${PATH}:${JAVA_HOME}/bin

after you save the changes, exit and restart your bash or just type in bash to start a new shell

Type in export to ensure paths are right.

Type in java -version to ensure Java is accessible.

Cursors make people overly apply a procedural mindset to a set-based environment.

And they are SLOW!!!

From SQLTeam:

Please note that cursors are the SLOWEST way to access data inside SQL Server. The should only be used when you truly need to access one row at a time. The only reason I can think of for that is to call a stored procedure on each row. In the Cursor Performance article I discovered that cursors are over thirty times slower than set based alternatives.

change the MaxClients directive. it is now on 256.

I'm surprised how nobody has suggested this yet. It's super clean and very explicit about which keys you want to keep.

const unfilteredObj = {a: ..., b:..., c:..., x:..., y:...}

const filterObject = ({a,b,c}) => ({a,b,c})
const filteredObject = filterObject(unfilteredObject)

Or if you want a dirty one liner:

const unfilteredObj = {a: ..., b:..., c:..., x:..., y:...}

const filteredObject = (({a,b,c})=>({a,b,c}))(unfilteredObject);

In a word - speed. An index for up to a million rows fits in a 32-bit word, so it can be used efficiently on 32-bit processors. Function arguments that fit in a CPU register are extremely efficient, while ones that are larger require accessing memory on each function call, a far slower operation. Updating a spreadsheet can be an intensive operation involving many cell references, so speed is important. Besides, the Excel team expects that anyone dealing with more than a million rows will be using a database rather than a spreadsheet.

If you even did not get scroll after doing what is written above .....

Set the android:layout_height="250dp"or you can say xdp where x can be any numerical value.

Technically, you could, but it would take a lot of work to get all browsers to print out the page exactly as it is displayed on screen. Also, most browsers force the URL, print date and page numbering on the print-out, which is not always desired. This cannot be altered or disabled.

Instead, I would advise to create a PDF based on the contents on screen and serve the PDF for downloading and/or printing. Although most available PDF libraries are paid, there are a few free alternatives available for creating basic PDFs.

Surely using array_map and if using a container implementing ArrayAccess to derive objects is just a smarter, semantic way to go about this?

Array map semantics are similar across most languages and implementations that I've seen. It's designed to return a modified array based upon input array element (high level ignoring language compile/runtime type preference); a loop is meant to perform more logic.

For retrieving objects by ID / PK, depending upon if you are using SQL or not (it seems suggested), I'd use a filter to ensure I get an array of valid PK's, then implode with comma and place into an SQL IN() clause to return the result-set. It makes one call instead of several via SQL, optimising a bit of the call->wait cycle. Most importantly my code would read well to someone from any language with a degree of competence and we don't run into mutability problems.

<?php

$arr = [0,1,2,3,4];
$arr2 = array_map(function($value) { return is_int($value) ? $value*2 : $value; }, $arr);
var_dump($arr);
var_dump($arr2);

vs

<?php

$arr = [0,1,2,3,4];
foreach($arr as $i => $item) {
    $arr[$i] = is_int($item) ? $item * 2 : $item;
}
var_dump($arr);

If you know what you are doing will never have mutability problems (bearing in mind if you intend upon overwriting $arr you could always $arr = array_map and be explicit.

I also encountered this problem because I install Ruby on Ubuntu via brightbox, and I thought ruby-dev is the trunk of ruby. So I did not install. Install ruby2.3-dev fixes it:

sudo apt-get install ruby2.3-dev

i = Your_int_value

Write bytes value like this for example:

the_file.write(i.to_bytes(2,"little"))

Depend of you int value size and the bit order your prefer

A cleaner alternative would be to use a Dictionary to handle parameters. They are key-value pairs after all.

private static readonly HttpClient httpclient;

static MyClassName()
{
    // HttpClient is intended to be instantiated once and re-used throughout the life of an application. 
    // Instantiating an HttpClient class for every request will exhaust the number of sockets available under heavy loads. 
    // This will result in SocketException errors.
    // https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=netframework-4.7.1
    httpclient = new HttpClient();    
} 

var url = "http://myserver/method";
var parameters = new Dictionary<string, string> { { "param1", "1" }, { "param2", "2" } };
var encodedContent = new FormUrlEncodedContent (parameters);

var response = await httpclient.PostAsync (url, encodedContent).ConfigureAwait (false);
if (response.StatusCode == HttpStatusCode.OK) {
    // Do something with response. Example get content:
    // var responseContent = await response.Content.ReadAsStringAsync ().ConfigureAwait (false);
}

Also dont forget to Dispose() httpclient, if you dont use the keyword using

As stated in the Remarks section of the HttpClient class in the Microsoft docs, HttpClient should be instantiated once and re-used.

Edit:

You may want to look into response.EnsureSuccessStatusCode(); instead of if (response.StatusCode == HttpStatusCode.OK).

You may want to keep your httpclient and dont Dispose() it. See: Do HttpClient and HttpClientHandler have to be disposed?

Edit:

Do not worry about using .ConfigureAwait(false) in .NET Core. For more details look at https://blog.stephencleary.com/2017/03/aspnetcore-synchronization-context.html

I was having the same problem and could not figure out what I was doing wrong. Turns out, the auto-complete for Android Studio was changing the text to either all caps or all lower case (depending on whether I typed in upper case or lower cast words before the auto-complete). The OS was not registering the name due to this issue and I would get the error regarding a missing permission. As stated above, ensure your permissions are labeled correctly:

Correct:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Incorrect:

<uses-permission android:name="ANDROID.PERMISSION.ACCESS_FINE_LOCATION" />

Incorrect:

<uses-permission android:name="android.permission.access_fine_location" />

Though this may seem trivial, its easy to overlook.

If there is some setting to make permissions non-case-sensitive, please add a comment with the instructions. Thank you!

Since the settings object is tied to that ajax call, you can simply add in the indexer as a custom property, which you can then access using this in the success callback:

//preloader for images on gallery pages
window.onload = function() {
    var urls = ["./img/party/","./img/wedding/","./img/wedding/tree/"];

    setTimeout(function() {
        for ( var i = 0; i < urls.length; i++ ) {
            $.ajax({
                url: urls[i],
                indexValue: i,
                success: function(data) {
                    image_link(data , this.indexValue);

                    function image_link(data, i) {
                        $(data).find("a:contains(.jpg)").each(function(){ 
                            console.log(i);
                            new Image().src = urls[i] + $(this).attr("href");
                        });
                    }
                }
            });
        };  
    }, 1000);       
};

Edit: Adding in an updated JSFiddle example, as they seem to have changed how their ECHO endpoints work: https://jsfiddle.net/djujx97n/26/.

To understand how this works see the "context" field on the ajaxSettings object: http://api.jquery.com/jquery.ajax/, specifically this note:

"The this reference within all callbacks is the object in the context option passed to $.ajax in the settings; if context is not specified, this is a reference to the Ajax settings themselves."

You can simply use setInterval to create such timer in Angular, Use this Code for timer -

timeLeft: number = 60;
  interval;

startTimer() {
    this.interval = setInterval(() => {
      if(this.timeLeft > 0) {
        this.timeLeft--;
      } else {
        this.timeLeft = 60;
      }
    },1000)
  }

  pauseTimer() {
    clearInterval(this.interval);
  }

<button (click)='startTimer()'>Start Timer</button>
<button (click)='pauseTimer()'>Pause</button>

<p>{{timeLeft}} Seconds Left....</p>

Working Example

Another way using Observable timer like below -

import { timer } from 'rxjs';

observableTimer() {
    const source = timer(1000, 2000);
    const abc = source.subscribe(val => {
      console.log(val, '-');
      this.subscribeTimer = this.timeLeft - val;
    });
  }

<p (click)="observableTimer()">Start Observable timer</p> {{subscribeTimer}}

Something throws an exception of type std::bad_alloc, indicating that you ran out of memory. This exception is propagated through until main, where it "falls off" your program and causes the error message you see.

Since nobody here knows what "RectInvoice", "rectInvoiceVector", "vect", "im" and so on are, we cannot tell you what exactly causes the out-of-memory condition. You didn't even post your real code, because w h looks like a syntax error.

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

It's very simple using System.Security.Cryptography.MD5:

using (var md5 = MD5.Create())
{
    using (var stream = File.OpenRead(filename))
    {
        return md5.ComputeHash(stream);
    }
}

(I believe that actually the MD5 implementation used doesn't need to be disposed, but I'd probably still do so anyway.)

How you compare the results afterwards is up to you; you can convert the byte array to base64 for example, or compare the bytes directly. (Just be aware that arrays don't override Equals. Using base64 is simpler to get right, but slightly less efficient if you're really only interested in comparing the hashes.)

If you need to represent the hash as a string, you could convert it to hex using BitConverter:

static string CalculateMD5(string filename)
{
    using (var md5 = MD5.Create())
    {
        using (var stream = File.OpenRead(filename))
        {
            var hash = md5.ComputeHash(stream);
            return BitConverter.ToString(hash).Replace("-", "").ToLowerInvariant();
        }
    }
}

- (NSDate *)earlierDate:(NSDate *)anotherDate

This returns the earlier of the receiver and anotherDate. If both are same, the receiver is returned.

Some time in the future, we can write it like this:

li:nth-child(2) {
    rotate: 15deg;
    translate:-20px 0px;        
}

This will become especially useful when applying individual classes on an element:

<div class="teaser important"></div>

.teaser{rotate:10deg;}
.important{scale:1.5 1.5;}

This syntax is defined in the in-progress CSS Transforms Level 2 specification, but can't find anything about current browser support other then chrome canary. Hope some day i'll come back and update browser support here ;)

Found the info in this article which you might want to check out regarding workarounds for current browsers.

Linux

If you're using Linux and .NET Core, see this question, you'll want to use

dotnet add package Newtonsoft.Json

And then add

using Newtonsoft.Json;

to any classes needing that.

Login into the database. then run the below query

select * from dba_role_privs where grantee = 'SCHEMA_NAME';

All the role granted to the schema will be listed.

Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.

Good day,

I know I am late to this party, but let me show you my answer.

const [windowSize, setWindowSize] = useState(null)

useEffect(() => {
    const handleResize = () => {
        setWindowSize(window.innerWidth)
    }

    window.addEventListener('resize', handleResize)

    return () => window.removeEventListener('resize', handleResize)
}, [])

Following the working sample, I have figured out solution for the case of pure component:

1. Declare component at app level
2. Do not init in component

The Markup Way:

<strong>I'm Bold!</strong> and <b>I'm Bold Too!</b>

The Styling Way:

.bold {
  font-weight:bold;
}

<span class="bold">I'm Bold!</span>

From: http://www.december.com/html/x1/

<b>

This element encloses text which should be rendered by the browser as boldface. Because the meaning of the B element defines the appearance of the content it encloses, this element is considered a "physical" markup element. As such, it doesn't convey the meaning of a semantic markup element such as strong.

<strong>

Description This element brackets text which should be strongly emphasized. Stronger than the em element.

<select id="ddlvalue" name="ddlvaluename">
<option value='0' disabled selected>Select Value</option>
<option value='1' >Value 1</option>
<option value='2' >Value 2</option>
</select>

<input type="submit" id="btn_submit" value="click me"/>



<script>
$('#btn_submit').on('click',function(){
      $('#ddlvalue').val(0);
});
</script>

Following worked for me:

SpingBoot 2.1.7.RELEASE

YAML Property (Notice value sourrounded by single quotes)

property:
   name: '{"key1": false, "key2": false, "key3": true}'

In Java/Kotlin annotate field with (Notice use of #) (For java no need to escape '$' with '\')

@Value("#{\${property.name}}")

A shorter version in Vanilla JS and in one line:

for (var link of document.querySelectorAll("link[rel=stylesheet]")) link.href = link.href.replace(/\?.*|$/, "?" + Date.now())

Or expanded:

for (var link of document.querySelectorAll("link[rel=stylesheet]")) {
  link.href = link.href.replace(/\?.*|$/, "?" + Date.now())
}

Just posting in case it help someone else. The cause of this error for me was a missing do after creating a form with form_with. Hope that may help someone else

The accepted answer is too long, other answers didn't work for me. I'm gonna leave this for future purpose.

Dim sKey, bFound
skey = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\SecurityHealth"

with CreateObject("WScript.Shell")
  on error resume next            ' turn off error trapping
    sValue = .regread(sKey)       ' read attempt
    bFound = (err.number = 0)     ' test for success
  on error goto 0                 ' restore error trapping
end with

If bFound Then
  MsgBox = "Registry Key Exist."
Else
  MsgBox = "Nope, it doesn't exist."
End If

Here's the list of the Registry Tree, choose your own base on your current task.

HKCR = HKEY_CLASSES_ROOT
HKCU = HKEY_CURRENT_USER
HKLM = HKEY_LOCAL_MACHINE
HKUS = HKEY_USERS
HKCC = HKEY_CURRENT_CONFIG

Python comes with a script that takes care of setting up the windows path file for you.

After installation, open command prompt

cmd

Go to the directory you installed Python in

cd C:\Python27

Run python and the win_add2path.py script in Tools\Scripts

python.exe Tools\Scripts\win_add2path.py

Now you can use python as a command anywhere.

Cleaner way, exploit shortcut evaluation of shell logical operators. Right side of the operator is executed only if left side is true.

[ ! -d /home/mlzboy/b2c2/shared/db ] && mkdir -p /home/mlzboy/b2c2/shared/db

this is what I do, python3.3. I was processing huge lists of sites, so failing on the timeout was vital for the job to run through the entire list.

command = "phantomjs --ignore-ssl-errors=true "+<your js file for phantom>
process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)

# make sure phantomjs has time to download/process the page
# but if we get nothing after 30 sec, just move on
try:
    output, errors = process.communicate(timeout=30)
except Exception as e:
    print("\t\tException: %s" % e)
    process.kill()

# output will be weird, decode to utf-8 to save heartache
phantom_output = ''
for out_line in output.splitlines():
    phantom_output += out_line.decode('utf-8')

You can use the tee command to redirect output:

/usr/bin/mysqldump -u user -pupasswd my-database | \
tee >(gzip -9 -c > /home/user/backup/mydatabase-backup-`date +\%m\%d_\%Y`.sql.gz)  | \
gzip> /home/user/backup2/mydatabase-backup-`date +\%m\%d_\%Y`.sql.gz 2>&1

see documentation here

selection=selection.values

this do things at a very fast way.

You're receiving this error because you did not pass a data variable to the DHT constructor.

aIKid and Alexander's answers are nice but it wont work because you still have to initialize self.data in the class constructor like this:

class DHT:
   def __init__(self, data=None):
      if data is None:
         data = {}
      else:
         self.data = data
      self.data['one'] = '1'
      self.data['two'] = '2'
      self.data['three'] = '3'
   def showData(self):
      print(self.data)

And then calling the method showData like this:

DHT().showData()

Or like this:

DHT({'six':6,'seven':'7'}).showData()

or like this:

# Build the class first
dht = DHT({'six':6,'seven':'7'})
# The call whatever method you want (In our case only 1 method available)
dht.showData()

Solved after 3 hours... I am using WAMP (PHP 7.2.4), PostgreSQL 10, Laravel 5.6.29. Loaded PHP extensions (pgsql, pdo_pgsql) from Wampserver 3.3, then I was able to connect to the PostgreSQL server with a simple php testcode from the www directory. But $ php artisan migrate still returned

PDOException::("could not find driver")

I checked the shell (git bash for windows) with $ php --ini, that returned C:\wamp64\bin\php\php7.2.4\php.ini instead of c:\wamp64\bin\apache\apache2.4.33\bin\php.ini, loaded by WAMP So you have to uncomment pgsql and pdo_pgsql extensions also in C:\wamp64\bin\php\php7.2.4\php.ini, and then migrate will work ...

While the accepted solution works, it is not complete. By far.

If you want to get all the keys, you need to take into consideration 2 more things:

x86 & x64 applications do not have access to the same registry. Basically x86 cannot normally access x64 registry. And some applications only register to the x64 registry.

and

some applications actually install into the CurrentUser registry instead of the LocalMachine

With that in mind, I managed to get ALL installed applications using the following code, WITHOUT using WMI

Here is the code:

List<string> installs = new List<string>();
List<string> keys = new List<string>() {
  @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",
  @"SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall"
};

// The RegistryView.Registry64 forces the application to open the registry as x64 even if the application is compiled as x86 
FindInstalls(RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64), keys, installs);
FindInstalls(RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64), keys, installs);

installs = installs.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList();
installs.Sort(); // The list of ALL installed applications



private void FindInstalls(RegistryKey regKey, List<string> keys, List<string> installed)
{
  foreach (string key in keys)
  {
    using (RegistryKey rk = regKey.OpenSubKey(key))
    {
      if (rk == null)
      {
        continue;
      }
      foreach (string skName in rk.GetSubKeyNames())
      {
        using (RegistryKey sk = rk.OpenSubKey(skName))
        {
          try
          {
            installed.Add(Convert.ToString(sk.GetValue("DisplayName")));
          }
          catch (Exception ex)
          { }
        }
      }
    }
  }
}

By definition, file: URLs are system-dependent, and they have little use. A URL as in your example works when used locally, i.e. the linking page itself is in the user’s computer. But browsers generally refuse to follow file: links on a page that it has fetched with the HTTP protocol, so that the page's own URL is an http: URL. When you click on such a link, nothing happens. The purpose is presumably security: to prevent a remote page from accessing files in the visitor’s computer. (I think this feature was first implemented in Mozilla, then copied to other browsers.)

So if you work with HTML documents in your computer, the file: URLs should work, though there are system-dependent issues in their syntax (how you write path names and file names in such a URL).

If you really need to work with an HTML document on your computers and another HTML document on a web server, the way to make links work is to use the local file as primary and, if needed, use client-side scripting to fetch the document from the server,

May be this helps some one who are looking for multiple date formats one after the other by willingly or unexpectedly. Please find the code: I am using moment.js format function on a current date as (today is 29-06-2020) var startDate = moment(new Date()).format('MM/DD/YY'); Result: 06/28/20

what happening is it retains only the year part :20 as "06/28/20", after If I run the statement : new Date(startDate) The result is "Mon Jun 28 1920 00:00:00 GMT+0530 (India Standard Time)",

Then, when I use another format on "06/28/20": startDate = moment(startDate ).format('MM-DD-YYYY'); Result: 06-28-1920, in google chrome and firefox browsers it gives correct date on second attempt as: 06-28-2020. But in IE it is having issues, from this I understood we can apply one dateformat on the given date, If we want second date format, it should be apply on the fresh date not on the first date format result. And also observe that for first time applying 'MM-DD-YYYY' and next 'MM-DD-YY' is working in IE. For clear understanding please find my question in the link: Date went wrong when using Momentjs date format in IE 11

Create a file named open_dos_here.cmd with the following lines:

%~d1
cd "%~p1"
call cmd

Put this file at any folder. Then, go to your Send To folder (Win+E; Alt+D;shell:sendto;Enter). Create a shortcut to point to this open_dos_here.cmd

Then, in any folder, select any file or sub-folder. Right-click and select "Send To" and then select open_dos_here.cmd to open the DOS in that folder.

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

To install a specific package:

conda install <pkg>=<version>

eg:

conda install matplotlib=1.4.3

You could sort the array in descending order and get the first item:

[267, 306, 108].sort(function(a,b){return b-a;})[0]

if (!s.match(/abc|def/g)) {
    alert("match");
}
else {
    alert("no match");
}

Add 3.1.1 in to properties like below than fix issue

<properties>
        <java.version>1.8</java.version>
        <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

Just Update Project => right click => Maven=> Update Project

I found it on this page: http://eslint.org/docs/user-guide/configuring

In package.json, this works:

"eslintConfig": {
  "globals": {
    "window": true
  }
}

//If url is something.domain.com this returns -> domain.com
function getDomain() {
  return window.location.hostname.replace(/([a-zA-Z0-9]+.)/,"");
}

Assuming you're running on a Windows machine...

1. Hit the F12 key
2. Select the Scripts, or Sources, tab in the developer tools
3. Click the little folder icon in the top level
4. Select your JavaScript file
5. Add a breakpoint by clicking on the line number on the left (adds a little blue marker)
6. Execute your JavaScript

Then during execution debugging you can do a handful of stepping motions...

• F8 Continue: Will continue until the next breakpoint
• F10 Step over: Steps over next function call (won't enter the library)
• F11 Step into: Steps into the next function call (will enter the library)
• Shift + F11 Step out: Steps out of the current function

Update

After reading your updated post; to debug your code I would recommend temporarily using the jQuery Development Source Code. Although this doesn't directly solve your problem, it will allow you to debug more easily. For what you're trying to achieve I believe you'll need to step-in to the library, so hopefully the production code should help you decipher what's happening.

How about something like this

PROXY = "149.215.113.110:70"

webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
    "httpProxy":PROXY,
    "ftpProxy":PROXY,
    "sslProxy":PROXY,
    "noProxy":None,
    "proxyType":"MANUAL",
    "class":"org.openqa.selenium.Proxy",
    "autodetect":False
}

# you have to use remote, otherwise you'll have to code it yourself in python to 
driver = webdriver.Remote("http://localhost:4444/wd/hub", webdriver.DesiredCapabilities.FIREFOX)

Unfortunately I can't comment with my newbie reputation, but I have a solution for the issue of the screen going blank, or at least this is what worked for me. Instead of setting the wrapper class inside of the errorPlacement function, set it immediately when you're setting the wrapper type.

$('#myForm').validate({
    errorElement: "div",
    wrapper: "div class=\"message\"",
    errorPlacement: function(error, element) {
        offset = element.offset();
        error.insertBefore(element);
        //error.addClass('message');  // add a class to the wrapper
        error.css('position', 'absolute');
        error.css('left', offset.left + element.outerWidth() + 5);
        error.css('top', offset.top - 3);
    }

});

I'm assuming doing it this way allows the validator to know which div elements to remove, instead of all of them. Worked for me but I'm not entirely sure why, so if someone could elaborate that might help others out a ton.

If the types of your items are all different, here is a class I made to get them more intuitively.

The usage of this class:

var t = TypedTuple.Create("hello", 1, new MyClass());
var s = t.Get<string>();
var i = t.Get<int>();
var c = t.Get<MyClass>();

Source code:

public static class TypedTuple
{
    public static TypedTuple<T1> Create<T1>(T1 t1)
    {
        return new TypedTuple<T1>(t1);
    }

for color in ['r', 'b', 'g', 'k', 'm']:
    plot(x, y, color=color)

I have a more automated solution for this.

HTML:

<form role="form" enctype="multipart/form-data" action="{{ $url }}" method="{{ $method }}">
    {{ csrf_field() }}

    <!-- You can add extra form fields here -->

    <input hidden id="file" name="file"/>

    <!-- You can add extra form fields here -->

    <div class="dropzone dropzone-file-area" id="fileUpload">
        <div class="dz-default dz-message">
            <h3 class="sbold">Drop files here to upload</h3>
            <span>You can also click to open file browser</span>
        </div>
    </div>

    <!-- You can add extra form fields here -->

    <button type="submit">Submit</button>
</form>

JavaScript:

Dropzone.options.fileUpload = {
    url: 'blackHole.php',
    addRemoveLinks: true,
    accept: function(file) {
        let fileReader = new FileReader();

        fileReader.readAsDataURL(file);
        fileReader.onloadend = function() {

            let content = fileReader.result;
            $('#file').val(content);
            file.previewElement.classList.add("dz-success");
        }
        file.previewElement.classList.add("dz-complete");
    }
}

Laravel:

// Get file content
$file = base64_decode(request('file'));

No need to disable DropZone Discovery and the normal form submit will be able to send the file with any other form fields through standard form serialization.

This mechanism stores the file contents as base64 string in the hidden input field when it gets processed. You can decode it back to binary string in PHP through the standard base64_decode() method.

I don't know whether this method will get compromised with large files but it works with ~40MB files.

Assuming your date column is an actual MySQL date column:

SELECT * FROM jokes WHERE date > DATE_SUB(NOW(), INTERVAL 1 DAY) ORDER BY score DESC;        
SELECT * FROM jokes WHERE date > DATE_SUB(NOW(), INTERVAL 1 WEEK) ORDER BY score DESC;
SELECT * FROM jokes WHERE date > DATE_SUB(NOW(), INTERVAL 1 MONTH) ORDER BY score DESC;

Detecting operating system and CPU type is not so easy to do portably. I have a sh script of about 100 lines that works across a very wide variety of Unix platforms: any system I have used since 1988.

The key elements are

• uname -p is processor type but is usually unknown on modern Unix platforms.

• uname -m will give the "machine hardware name" on some Unix systems.

• /bin/arch, if it exists, will usually give the type of processor.

• uname with no arguments will name the operating system.

Eventually you will have to think about the distinctions between platforms and how fine you want to make them. For example, just to keep things simple, I treat i386 through i686 , any "Pentium*" and any "AMD*Athlon*" all as x86.

My ~/.profile runs an a script at startup which sets one variable to a string indicating the combination of CPU and operating system. I have platform-specific bin, man, lib, and include directories that get set up based on that. Then I set a boatload of environment variables. So for example, a shell script to reformat mail can call, e.g., $LIB/mailfmt which is a platform-specific executable binary.

If you want to cut corners, uname -m and plain uname will tell you what you want to know on many platforms. Add other stuff when you need it. (And use case, not nested if!)

I'm sure you are using a old version. You must use the last version available at master branch:

You could use these open source PHP Switch Scripts, which were designed specifically for use in Ubuntu 16.04 LTS.

https://github.com/rapidwebltd/php-switch-scripts

There is a setup.sh script which installs all required dependencies for PHP 5.6, 7.0, 7.1 & 7.2. Once this is complete, you can just run one of the following switch scripts to change the PHP CLI and Apache 2 module version.

./switch-to-php-5.6.sh
./switch-to-php-7.0.sh
./switch-to-php-7.1.sh
./switch-to-php-7.2.sh

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

Adding MaxHeight and VerticalScrollBarVisibility="Auto" on the DataGrid solved my problem.

If you want to suppress this warning in elegant way (because you are sure that accessibility is not needed for this particular ImageView), you can use special attribute:

android:importantForAccessibility="no"

You can use regular expressions for extracting the number from string. Lets check it. Suppose this is the string mixing text and numbers 'stack12345overflow569'. This one should work:

select regexp_replace('stack12345overflow569', '[[:alpha:]]|_') as numbers from dual;

which will return "12345569".

also you can use this one:

select regexp_replace('stack12345overflow569', '[^0-9]', '') as numbers,
       regexp_replace('Stack12345OverFlow569', '[^a-z and ^A-Z]', '') as characters
from dual

which will return "12345569" for numbers and "StackOverFlow" for characters.

If your table is already working with tabular, then easiest is to switch it to longtable, remembering to add

\usepackage{longtable}

For example:

\begin{longtable}{ll}
  2014--2015 & Something cool\footnote{first footnote} \\
  2016-- & Something cooler\footnote{second footnote}
\end{longtable}

Did you try format?

@font-face {
  font-family: 'The name of the Font Family Here';
  src: URL('font.ttf') format('truetype');
}

Read this article: http://css-tricks.com/snippets/css/using-font-face/

Also, might depend on browser as well.

None of the answers worked until I removed the HasNoKey() method from the entity. Dont forget to remove this from your data context or the [Key] attribute will not fix anything.

I faced same issue in eclipse neon simple maven java project

Its resolve me to display error on project

Hope it's will helpful

Thansk

I encountered this using it in Mac, resolved it by using --ignore-platform-reqs option.

composer install --ignore-platform-reqs

you can use just javascript for it

var total =10.8
(total).toFixed(2); 10.80


alert(total.toFixed(2))); 

There's no easy way to do this, but something like this will work:

SELECT ET.TrainingID, 
  ET.CompletedDate, 
  ET.Notes
FROM 
HR_EmployeeTrainings ET
inner join
(
  select TrainingID, Max(CompletedDate) as CompletedDate
  FROM HR_EmployeeTrainings
  WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID)
  GROUP BY AvantiRecID, TrainingID  
) ET2 
  on ET.TrainingID = ET2.TrainingID
  and ET.CompletedDate = ET2.CompletedDate

In fact, Objective-C doesn't have abstract classes, but you can use Protocols to achieve the same effect. Here is the sample:

CustomProtocol.h

#import <Foundation/Foundation.h>

@protocol CustomProtocol <NSObject>
@required
- (void)methodA;
@optional
- (void)methodB;
@end

TestProtocol.h

#import <Foundation/Foundation.h>
#import "CustomProtocol.h"

@interface TestProtocol : NSObject <CustomProtocol>

@end

TestProtocol.m

#import "TestProtocol.h"

@implementation TestProtocol

- (void)methodA
{
  NSLog(@"methodA...");
}

- (void)methodB
{
  NSLog(@"methodB...");
}
@end

You can use exit method to quit an ios app :

exit(0);

You should say same alert message and ask him to quit

Another way is by using [[NSThread mainThread] exit]

However you should not do this way

According to Apple, your app should not terminate on its own. Since the user did not hit the Home button, any return to the Home screen gives the user the impression that your app crashed. This is confusing, non-standard behavior and should be avoided.

The answer is NO you can't. Why?

Because the LDAP standard describes a LDAP-SEARCH as kind of function with 4 parameters:

1. The node where the search should begin, which is a Distinguish Name (DN)
2. The attributes you want to be brought back
3. The depth of the search (base, one-level, subtree)
4. The filter

You are interested in the filter. You've got a summary here (it's provided by Microsoft for Active Directory, it's from a standard). The filter is composed, in a boolean way, by expression of the type Attribute Operator Value.

So the filter you give does not mean anything.

On the theoretical point of view there is ExtensibleMatch that allows buildind filters on the DN path, but it's not supported by Active Directory.

As far as I know, you have to use an attribute in AD to make the distinction for users in the two OUs.

It can be any existing discriminator attribute, or, for example the attribute called OU which is inherited from organizationalPerson class. you can set it (it's not automatic, and will not be maintained if you move the users) with "staff" for some users and "vendors" for others and them use the filter:

(&(objectCategory=person)(|(ou=staff)(ou=vendors)))

is null can be used to check whether null data is coming from a query as in following example:

 declare @Mem varchar(20),@flag int
select @mem=MemberClub from [dbo].[UserMaster] where UserID=@uid
if(@Mem is null)
begin
    set @flag= 0;
end
else
begin
    set @flag=1;
end
return @flag;

CREATE TABLE new_table LIKE old_table;

or u can use this

CREATE TABLE new_table as SELECT * FROM old_table WHERE 1 GROUP BY [column to remove duplicates by];

If you are looking to style a file input element, look at open file dialog box in javascript. If you are looking to grab the files associated with a file input element, you must do something like this:

inputElement.onchange = function(event) {
   var fileList = inputElement.files;
   //TODO do something with fileList.  
}

See this MDN article for more info on the FileList type.

Note that the code above will only work in browsers that support the File API. For IE9 and earlier, for example, you only have access to the file name. The input element has no files property in non-File API browsers.

The following will give you the hex encoding for the low byte of each character, which looks like what you're asking for:

StringBuilder sb = new StringBuilder();
foreach (char c in asciiString)
{
    uint i = (uint)c;
    sb.AppendFormat("{0:X2}", (i & 0xff));
}
return sb.ToString();

Var doesn't let you, the programmer, declare a variable because Javascript doesn't have variables. Javascript has objects. Var declares a name to an undefined object, explicitly. Assignment assigns a name as a handle to an object that has been given a value.

Using var tells the Javacript interpreter two things:

1. not to use delegation reverse traversal look up value for the name, instead use this one
2. not to delete the name

Omission of var tells the Javacript interpreter to use the first-found previous instance of an object with the same name.

Var as a keyword arose from a poor decision by the language designer much in the same way that Javascript as a name arose from a poor decision.

ps. Study the code examples above.

Call visudo and add this:

user1 ALL=(user2) NOPASSWD: /home/user2/bin/test.sh

The command paths must be absolute! Then call sudo -u user2 /home/user2/bin/test.sh from a user1 shell. Done.

Having installed tomcat with brew the solution for me was:

sudo chmod -R 777 /usr/local/Cellar/tomcat/<your_version>

Good question. You will need to modify the HTML itself rather than rely on DOM properties.

var opt = $("option[val=ID]"),
    html = $("<div>").append(opt.clone()).html();
html = html.replace(/\>/, ' selected="selected">');
opt.replaceWith(html);

The code grabs the option element for Indonesia, clones it and puts it into a new div (not in the document) to retrieve the full HTML string: <option value="ID">Indonesia</option>.

It then does a string replace to add the attribute selected="selected" as a string, before replacing the original option with this new one.

I tested it on IE7. See it with the reset button working properly here: http://jsfiddle.net/XmW49/

If you somehow change scrollView contentSize (ex. add something to stackView which is inside scrollView) you must call scrollView.layoutIfNeeded() before scrolling, otherwise it does nothing.

Example:

scrollView.layoutIfNeeded()
let bottomOffset = CGPoint(x: 0, y: scrollView.contentSize.height - scrollView.bounds.size.height + scrollView.contentInset.bottom)
if(bottomOffset.y > 0) {
    scrollView.setContentOffset(bottomOffset, animated: true)
}

It is being pointed out not directly in the file which is caused the error. But it is actually triggered in a controller file. It happens when a return value from a method defined inside in a controller file is set on a boolean value. It must not be set on a boolean type but on the other hand, it must be set or given a value of a string type. It can be shown as follows :

public function saveFormSummary(Request $request) {
      ... 
      $status = true;
      return $status;
}

Given the return value of a boolean type above in a method, to be able to solve the problem to handle the error specified. Just change the type of the return value into a string type

as follows :

public function saveFormSummary(Request $request) {
      ... 
      $status = "true";
      return $status;
}

There're two kind of Django "projects" that I have in my ~/projects/ directory, both have a bit different structure.:

• Stand-alone websites
• Pluggable applications

Stand-alone website

Mostly private projects, but doesn't have to be. It usually looks like this:

~/projects/project_name/

docs/               # documentation
scripts/
  manage.py         # installed to PATH via setup.py
project_name/       # project dir (the one which django-admin.py creates)
  apps/             # project-specific applications
    accounts/       # most frequent app, with custom user model
    __init__.py
    ...
  settings/         # settings for different environments, see below
    __init__.py
    production.py
    development.py
    ...
        
  __init__.py       # contains project version
  urls.py
  wsgi.py
static/             # site-specific static files
templates/          # site-specific templates
tests/              # site-specific tests (mostly in-browser ones)
tmp/                # excluded from git
setup.py
requirements.txt
requirements_dev.txt
pytest.ini
...

Settings

The main settings are production ones. Other files (eg. staging.py, development.py) simply import everything from production.py and override only necessary variables.

For each environment, there are separate settings files, eg. production, development. I some projects I have also testing (for test runner), staging (as a check before final deploy) and heroku (for deploying to heroku) settings.

Requirements

I rather specify requirements in setup.py directly. Only those required for development/test environment I have in requirements_dev.txt.

Some services (eg. heroku) requires to have requirements.txt in root directory.

setup.py

Useful when deploying project using setuptools. It adds manage.py to PATH, so I can run manage.py directly (anywhere).

Project-specific apps

I used to put these apps into project_name/apps/ directory and import them using relative imports.

Templates/static/locale/tests files

I put these templates and static files into global templates/static directory, not inside each app. These files are usually edited by people, who doesn't care about project code structure or python at all. If you are full-stack developer working alone or in a small team, you can create per-app templates/static directory. It's really just a matter of taste.

The same applies for locale, although sometimes it's convenient to create separate locale directory.

Tests are usually better to place inside each app, but usually there is many integration/functional tests which tests more apps working together, so global tests directory does make sense.

Tmp directory

There is temporary directory in project root, excluded from VCS. It's used to store media/static files and sqlite database during development. Everything in tmp could be deleted anytime without any problems.

Virtualenv

I prefer virtualenvwrapper and place all venvs into ~/.venvs directory, but you could place it inside tmp/ to keep it together.

Project template

I've created project template for this setup, django-start-template

Deployment

Deployment of this project is following:

source $VENV/bin/activate
export DJANGO_SETTINGS_MODULE=project_name.settings.production
git pull
pip install -r requirements.txt

# Update database, static files, locales
manage.py syncdb  --noinput
manage.py migrate
manage.py collectstatic --noinput
manage.py makemessages -a
manage.py compilemessages

# restart wsgi
touch project_name/wsgi.py

You can use rsync instead of git, but still you need to run batch of commands to update your environment.

Recently, I made django-deploy app, which allows me to run single management command to update environment, but I've used it for one project only and I'm still experimenting with it.

Sketches and drafts

Draft of templates I place inside global templates/ directory. I guess one can create folder sketches/ in project root, but haven't used it yet.

Pluggable application

These apps are usually prepared to publish as open-source. I've taken example below from django-forme

~/projects/django-app/

docs/
app/
tests/
example_project/
LICENCE
MANIFEST.in
README.md
setup.py
pytest.ini
tox.ini
.travis.yml
...

Name of directories is clear (I hope). I put test files outside app directory, but it really doesn't matter. It is important to provide README and setup.py, so package is easily installed through pip.

After getting the element as jQuery object via other means than its class, then

var className = $('#sidebar div:eq(14)').attr('class');

should do the trick. For the ID use .attr('id').

If you are inside an event handler or other jQuery method, where the element is the pure DOM node without wrapper, you can use:

this.className // for classes, and
this.id // for IDs

Both are standard DOM methods and well supported in all browsers.

I append one space for every element of the hash to see it well:

print map {$_ . " "} %h, "\n";

Try this code:

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({                                            
     url: 'api.php',                        
     data: 'id1='+q+'',                                                         
     dataType: 'json',
     async:false,                    
     success: function(data)          
     {   
        id = data[0];              
        vname = data[1];
     },
    complete: function (data) {
      printWithAjax(); 
     }
    });

  }//end of the for statement
  }//end of ajax call function

The "complete" function executes only after the "success" of ajax. So try to call the printWithAjax() on "complete". This should work for you.

Please read PEP8. You're swaying pretty far from python conventions.

If you want a list of lists of each line split by comma, I'd do this:

l = []
for line in in_file:
    l.append(line.split(','))

You'll get a newline on each record. If you don't want that:

l = []
for line in in_file:
    l.append(line.rstrip().split(','))

ISO standard C++ doesn't let you do this. If it did, the syntax would probably be:

a::a(void) :
b({2,3})
{
    // other initialization stuff
}

Or something along those lines. From your question it actually sounds like what you want is a constant class (aka static) member that is the array. C++ does let you do this. Like so:

#include <iostream>

class A 
{
public:
    A();
    static const int a[2];
};

const int A::a[2] = {0, 1};

A::A()
{
}

int main (int argc, char * const argv[]) 
{
    std::cout << "A::a => " << A::a[0] << ", " << A::a[1] << "\n";
    return 0;
}

The output being:

A::a => 0, 1

Now of course since this is a static class member it is the same for every instance of class A. If that is not what you want, ie you want each instance of A to have different element values in the array a then you're making the mistake of trying to make the array const to begin with. You should just be doing this:

#include <iostream>

You can try: .order_by(ClientTotal.id.desc())

session = Session()
auth_client_name = 'client3' 
result_by_auth_client = session.query(ClientTotal).filter(ClientTotal.client ==
auth_client_name).order_by(ClientTotal.id.desc()).all()

for rbac in result_by_auth_client:
    print(rbac.id) 
session.close()
