A negative lookahead says, at this position, the following regex can not match.

Let's take a simplified example:

a(?!b(?!c))

a      Match: (?!b) succeeds
ac     Match: (?!b) succeeds
ab     No match: (?!b(?!c)) fails
abe    No match: (?!b(?!c)) fails
abc    Match: (?!b(?!c)) succeeds

The last example is a double negation: it allows a b followed by c. The nested negative lookahead becomes a positive lookahead: the c should be present.

In each example, only the a is matched. The lookahead is only a condition, and does not add to the matched text.

Another way:

x=$'Some\nstring'
readarray -t y <<<"$x"

Or, if you don't have bash 4, the bash 3.2 equivalent:

IFS=$'\n' read -rd '' -a y <<<"$x"

You can also do it the way you were initially trying to use:

y=(${x//$'\n'/ })

This, however, will not function correctly if your string already contains spaces, such as 'line 1\nline 2'. To make it work, you need to restrict the word separator before parsing it:

IFS=$'\n' y=(${x//$'\n'/ })

...and then, since you are changing the separator, you don't need to convert the \n to space anymore, so you can simplify it to:

IFS=$'\n' y=($x)

This approach will function unless $x contains a matching globbing pattern (such as "*") - in which case it will be replaced by the matched file name(s). The read/readarray methods require newer bash versions, but work in all cases.

From my HomeController I want to call this Method and convert Json response to List

No you don't. You really don't want to add the overhead of an HTTP call and (de)serialization when the code is within reach. It's even in the same assembly!

Your ApiController goes against (my preferred) convention anyway. Let it return a concrete type:

public IEnumerable<QDocumentRecord> GetAllRecords()
{
    listOfFiles = ...
    return listOfFiles;
}

If you don't want that and you're absolutely sure you need to return HttpResponseMessage, then still there's absolutely no need to bother with calling JsonConvert.SerializeObject() yourself:

return Request.CreateResponse<List<QDocumentRecord>>(HttpStatusCode.OK, listOfFiles);

Then again, you don't want business logic in a controller, so you extract that into a class that does the work for you:

public class FileListGetter
{
    public IEnumerable<QDocumentRecord> GetAllRecords()
    {
        listOfFiles = ...
        return listOfFiles;
    }
}

Either way, then you can call this class or the ApiController directly from your MVC controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var listOfFiles = new DocumentsController().GetAllRecords();
        // OR
        var listOfFiles = new FileListGetter().GetAllRecords();

        return View(listOfFiles);
    }
}

But if you really, really must do an HTTP request, you can use HttpWebRequest, WebClient, HttpClient or RestSharp, for all of which plenty of tutorials exist.

No. We cannot alter the constraint, only thing we can do is drop and recreate it

This is simple way to Display Div using:-

$("#musicinfo").show();  //or
$("#musicinfo").css({'display':'block'});  //or
$("#musicinfo").toggle("slow");   //or
$("#musicinfo").fadeToggle();    //or

If the value returned is null, use:

if(value.isEmpty());

Sometime to check null, if(value == null) in java, it might not give true even the String is null.

In shell you can use cal -j YYYY which prints the julian day of the year, If the last julian day is 366, then it is a leap year.

$ function check_leap_year
 {
  year=$1
   if [ `cal -j $year | awk 'NF>0' | awk 'END { print $NF } '` -eq 366 ];
   then
      echo "$year -> Leap Year";
   else
      echo "$year -> Normal Year" ;
   fi
 }
$ check_leap_year 1900
1900 -> Normal Year
$ check_leap_year 2000
2000 -> Leap Year
$ check_leap_year 2001
2001 -> Normal Year
$ check_leap_year 2020
2020 -> Leap Year
$

Using awk, you can do

$ awk -v year=1900 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
365
$ awk -v year=2000 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
366
$ awk -v year=2001 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
365
$ awk -v year=2020 ' BEGIN { jul=strftime("%j",mktime(year " 12 31 0 0 0 ")); print jul } '
366
$

I had this error because I had two JS Functions with the same name

The short answer, or TL;DR

Basically, eval is used to evaluate a single dynamically generated Python expression, and exec is used to execute dynamically generated Python code only for its side effects.

eval and exec have these two differences:

1. eval accepts only a single expression, exec can take a code block that has Python statements: loops, try: except:, class and function/method definitions and so on.

   An expression in Python is whatever you can have as the value in a variable assignment:

   a_variable = (anything you can put within these parentheses is an expression)
   

2. eval returns the value of the given expression, whereas exec ignores the return value from its code, and always returns None (in Python 2 it is a statement and cannot be used as an expression, so it really does not return anything).

In versions 1.0 - 2.7, exec was a statement, because CPython needed to produce a different kind of code object for functions that used exec for its side effects inside the function.

In Python 3, exec is a function; its use has no effect on the compiled bytecode of the function where it is used.

Thus basically:

>>> a = 5
>>> eval('37 + a')   # it is an expression
42
>>> exec('37 + a')   # it is an expression statement; value is ignored (None is returned)
>>> exec('a = 47')   # modify a global variable as a side effect
>>> a
47
>>> eval('a = 47')  # you cannot evaluate a statement
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    a = 47
      ^
SyntaxError: invalid syntax

The compile in 'exec' mode compiles any number of statements into a bytecode that implicitly always returns None, whereas in 'eval' mode it compiles a single expression into bytecode that returns the value of that expression.

>>> eval(compile('42', '<string>', 'exec'))  # code returns None
>>> eval(compile('42', '<string>', 'eval'))  # code returns 42
42
>>> exec(compile('42', '<string>', 'eval'))  # code returns 42,
>>>                                          # but ignored by exec

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>', 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Actually the statement "eval accepts only a single expression" applies only when a string (which contains Python source code) is passed to eval. Then it is internally compiled to bytecode using compile(source, '<string>', 'eval') This is where the difference really comes from.

If a code object (which contains Python bytecode) is passed to exec or eval, they behave identically, excepting for the fact that exec ignores the return value, still returning None always. So it is possible use eval to execute something that has statements, if you just compiled it into bytecode before instead of passing it as a string:

>>> eval(compile('if 1: print("Hello")', '<string>', 'exec'))
Hello
>>>

works without problems, even though the compiled code contains statements. It still returns None, because that is the return value of the code object returned from compile.

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>'. 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

The longer answer, a.k.a the gory details

exec and eval

The exec function (which was a statement in Python 2) is used for executing a dynamically created statement or program:

>>> program = '''
for i in range(3):
    print("Python is cool")
'''
>>> exec(program)
Python is cool
Python is cool
Python is cool
>>> 

The eval function does the same for a single expression, and returns the value of the expression:

>>> a = 2
>>> my_calculation = '42 * a'
>>> result = eval(my_calculation)
>>> result
84

exec and eval both accept the program/expression to be run either as a str, unicode or bytes object containing source code, or as a code object which contains Python bytecode.

If a str/unicode/bytes containing source code was passed to exec, it behaves equivalently to:

exec(compile(source, '<string>', 'exec'))

and eval similarly behaves equivalent to:

eval(compile(source, '<string>', 'eval'))

Since all expressions can be used as statements in Python (these are called the Expr nodes in the Python abstract grammar; the opposite is not true), you can always use exec if you do not need the return value. That is to say, you can use either eval('my_func(42)') or exec('my_func(42)'), the difference being that eval returns the value returned by my_func, and exec discards it:

>>> def my_func(arg):
...     print("Called with %d" % arg)
...     return arg * 2
... 
>>> exec('my_func(42)')
Called with 42
>>> eval('my_func(42)')
Called with 42
84
>>> 

Of the 2, only exec accepts source code that contains statements, like def, for, while, import, or class, the assignment statement (a.k.a a = 42), or entire programs:

>>> exec('for i in range(3): print(i)')
0
1
2
>>> eval('for i in range(3): print(i)')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Both exec and eval accept 2 additional positional arguments - globals and locals - which are the global and local variable scopes that the code sees. These default to the globals() and locals() within the scope that called exec or eval, but any dictionary can be used for globals and any mapping for locals (including dict of course). These can be used not only to restrict/modify the variables that the code sees, but are often also used for capturing the variables that the executed code creates:

>>> g = dict()
>>> l = dict()
>>> exec('global a; a, b = 123, 42', g, l)
>>> g['a']
123
>>> l
{'b': 42}

(If you display the value of the entire g, it would be much longer, because exec and eval add the built-ins module as __builtins__ to the globals automatically if it is missing).

In Python 2, the official syntax for the exec statement is actually exec code in globals, locals, as in

>>> exec 'global a; a, b = 123, 42' in g, l

However the alternate syntax exec(code, globals, locals) has always been accepted too (see below).

compile

The compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1) built-in can be used to speed up repeated invocations of the same code with exec or eval by compiling the source into a code object beforehand. The mode parameter controls the kind of code fragment the compile function accepts and the kind of bytecode it produces. The choices are 'eval', 'exec' and 'single':

• 'eval' mode expects a single expression, and will produce bytecode that when run will return the value of that expression:

  >>> dis.dis(compile('a + b', '<string>', 'eval'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 RETURN_VALUE
  

• 'exec' accepts any kinds of python constructs from single expressions to whole modules of code, and executes them as if they were module top-level statements. The code object returns None:

  >>> dis.dis(compile('a + b', '<string>', 'exec'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 POP_TOP                             <- discard result
                8 LOAD_CONST               0 (None)   <- load None on stack
               11 RETURN_VALUE                        <- return top of stack
  

• 'single' is a limited form of 'exec' which accepts a source code containing a single statement (or multiple statements separated by ;) if the last statement is an expression statement, the resulting bytecode also prints the repr of the value of that expression to the standard output(!).

  An if-elif-else chain, a loop with else, and try with its except, else and finally blocks is considered a single statement.

  A source fragment containing 2 top-level statements is an error for the 'single', except in Python 2 there is a bug that sometimes allows multiple toplevel statements in the code; only the first is compiled; the rest are ignored:

  In Python 2.7.8:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  >>> a
  5
  

  And in Python 3.4.2:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<string>", line 1
      a = 5
          ^
  SyntaxError: multiple statements found while compiling a single statement
  

  This is very useful for making interactive Python shells. However, the value of the expression is not returned, even if you eval the resulting code.

Thus greatest distinction of exec and eval actually comes from the compile function and its modes.

In addition to compiling source code to bytecode, compile supports compiling abstract syntax trees (parse trees of Python code) into code objects; and source code into abstract syntax trees (the ast.parse is written in Python and just calls compile(source, filename, mode, PyCF_ONLY_AST)); these are used for example for modifying source code on the fly, and also for dynamic code creation, as it is often easier to handle the code as a tree of nodes instead of lines of text in complex cases.

While eval only allows you to evaluate a string that contains a single expression, you can eval a whole statement, or even a whole module that has been compiled into bytecode; that is, with Python 2, print is a statement, and cannot be evalled directly:

>>> eval('for i in range(3): print("Python is cool")')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print("Python is cool")
      ^
SyntaxError: invalid syntax

compile it with 'exec' mode into a code object and you can eval it; the eval function will return None.

>>> code = compile('for i in range(3): print("Python is cool")',
                   'foo.py', 'exec')
>>> eval(code)
Python is cool
Python is cool
Python is cool

If one looks into eval and exec source code in CPython 3, this is very evident; they both call PyEval_EvalCode with same arguments, the only difference being that exec explicitly returns None.

Syntax differences of exec between Python 2 and Python 3

One of the major differences in Python 2 is that exec is a statement and eval is a built-in function (both are built-in functions in Python 3). It is a well-known fact that the official syntax of exec in Python 2 is exec code [in globals[, locals]].

Unlike majority of the Python 2-to-3 porting guides seem to suggest, the exec statement in CPython 2 can be also used with syntax that looks exactly like the exec function invocation in Python 3. The reason is that Python 0.9.9 had the exec(code, globals, locals) built-in function! And that built-in function was replaced with exec statement somewhere before Python 1.0 release.

Since it was desirable to not break backwards compatibility with Python 0.9.9, Guido van Rossum added a compatibility hack in 1993: if the code was a tuple of length 2 or 3, and globals and locals were not passed into the exec statement otherwise, the code would be interpreted as if the 2nd and 3rd element of the tuple were the globals and locals respectively. The compatibility hack was not mentioned even in Python 1.4 documentation (the earliest available version online); and thus was not known to many writers of the porting guides and tools, until it was documented again in November 2012:

The first expression may also be a tuple of length 2 or 3. In this case, the optional parts must be omitted. The form exec(expr, globals) is equivalent to exec expr in globals, while the form exec(expr, globals, locals) is equivalent to exec expr in globals, locals. The tuple form of exec provides compatibility with Python 3, where exec is a function rather than a statement.

Yes, in CPython 2.7 that it is handily referred to as being a forward-compatibility option (why confuse people over that there is a backward compatibility option at all), when it actually had been there for backward-compatibility for two decades.

Thus while exec is a statement in Python 1 and Python 2, and a built-in function in Python 3 and Python 0.9.9,

>>> exec("print(a)", globals(), {'a': 42})
42

has had identical behaviour in possibly every widely released Python version ever; and works in Jython 2.5.2, PyPy 2.3.1 (Python 2.7.6) and IronPython 2.6.1 too (kudos to them following the undocumented behaviour of CPython closely).

What you cannot do in Pythons 1.0 - 2.7 with its compatibility hack, is to store the return value of exec into a variable:

Python 2.7.11+ (default, Apr 17 2016, 14:00:29) 
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = exec('print(42)')
  File "<stdin>", line 1
    a = exec('print(42)')
           ^
SyntaxError: invalid syntax

(which wouldn't be useful in Python 3 either, as exec always returns None), or pass a reference to exec:

>>> call_later(exec, 'print(42)', delay=1000)
  File "<stdin>", line 1
    call_later(exec, 'print(42)', delay=1000)
                  ^
SyntaxError: invalid syntax

Which a pattern that someone might actually have used, though unlikely;

Or use it in a list comprehension:

>>> [exec(i) for i in ['print(42)', 'print(foo)']
  File "<stdin>", line 1
    [exec(i) for i in ['print(42)', 'print(foo)']
        ^
SyntaxError: invalid syntax

which is abuse of list comprehensions (use a for loop instead!).

I did all of them but didn't work, I find out should stop php artisan serve(Ctrl + C) and start php artisan serve again.

We just ran into this same issue. Our Cpanel has expanded from PHP only to PHP and .NET and defaulted to .NET.

Not using media queries is nice because it allows scaling the font size gradually.

Using vw units will adjust the font size relative to the view port size.

Directly converting vw units to font size will make it difficult to hit to the sweet spot for both mobile resolutions and desktop.

I recommend trying something like:

body {
    font-size: calc(0.5em + 1vw);
}

The only subquery appears to be this - try adding a ROWNUM limit to the where to be sure:

(SELECT C.I_WORKDATE
         FROM T_COMPENSATION C
         WHERE C.I_COMPENSATEDDATE = A.I_REQDATE AND ROWNUM <= 1
         AND C.I_EMPID = A.I_EMPID)

You do need to investigate why this isn't unique, however - e.g. the employee might have had more than one C.I_COMPENSATEDDATE on the matched date.

For performance reasons, you should also see if the lookup subquery can be rearranged into an inner / left join, i.e.

 SELECT 
    ...
    REPLACE(TO_CHAR(C.I_WORKDATE, 'DD-Mon-YYYY'),
            ' ',
            '') AS WORKDATE,
    ...
 INNER JOIN T_EMPLOYEE_MS E
    ...
     LEFT OUTER JOIN T_COMPENSATION C
          ON C.I_COMPENSATEDDATE = A.I_REQDATE
          AND C.I_EMPID = A.I_EMPID
    ...

SELECT user_id 
FROM user_logs 
WHERE login_date BETWEEN '2014-02-01' AND '2014-03-01'

Between keyword works exceptionally for a date. it assumes the time is at 00:00:00 (i.e. midnight) for dates.

This section of the boto3 documentation is helpful.

Here's what worked for me:

Short ways to write lines of text to a file in R could be realised with cat or writeLines as already shown in many answers. Some of the shortest possibilities might be:

cat("Hello\nWorld", file="output.txt")
writeLines("Hello\nWorld", "output.txt")

In case you don't like the "\n" you could also use the following style:

cat("Hello
World", file="output.txt")

writeLines("Hello
World", "output.txt")

While writeLines adds a newline at the end of the file what is not the case for cat. This behaviour could be adjusted by:

writeLines("Hello\nWorld", "output.txt", sep="") #No newline at end of file
cat("Hello\nWorld\n", file="output.txt") #Newline at end of file
cat("Hello\nWorld", file="output.txt", sep="\n") #Newline at end of file

But main difference is that cat uses R objects and writeLines a character vector as argument. So writing out e.g. the numbers 1:10 needs to be casted for writeLines while it can be used as it is in cat:

cat(1:10)
writeLines(as.character(1:10))

and cat can take many objects but writeLines only one vector:

cat("Hello", "World", sep="\n")
writeLines(c("Hello", "World"))

I use the following code:

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()
    fmt.Println("\nToday:", now)

    after := now.Add(1 * time.Minute)
    fmt.Println("\nAdd 1 Minute:", after)

    for {
        fmt.Println("test")
        time.Sleep(10 * time.Second)

        now = time.Now()

        if now.After(after) {
            break
        }
    }

    fmt.Println("done")
}

It is more simple and works fine to me.

I think I can ignore most if not all of that. I'm doing an ssh into the linux box using mobaXterm on my windows pc, so it's displaying its window on my pc. My linux box is headless.

You can use undocumented method android.app.ActivityThread.currentPackageName() :

Class<?> clazz = Class.forName("android.app.ActivityThread");
Method method  = clazz.getDeclaredMethod("currentPackageName", null);
String appPackageName = (String) method.invoke(clazz, null);

Caveat: This must be done on the main thread of the application.

Thanks to this blog post for the idea: http://blog.javia.org/static-the-android-application-package/ .

A list in a flask can be easily jsonify using jsonify like:

from flask import Flask,jsonify
app = Flask(__name__)

tasks = [
    {
        'id':1,
        'task':'this is first task'
    },
    {
        'id':2,
        'task':'this is another task'
    }
]

@app.route('/app-name/api/v0.1/tasks',methods=['GET'])
def get_tasks():
    return jsonify({'tasks':tasks})  #will return the json

if(__name__ == '__main__'):
    app.run(debug = True)

Pass the object:

doSomething(this)

You can get all data from object:

function(obj){
    var value = obj.value;
    var id = obj.id;
}

Or pass the id only:

doSomething(this.id)

Get the object and after that value:

function(id){
    var value = document.getElementById(id).value;  
}

In the Terminal type

pip show some_package_name

Example

pip show matplotlib

If you don't want to group your result, use a window function.

You didn't state your DBMS, but this is ANSI SQL:

SELECT AccountNumber, 
       Bill, 
       BillDate, 
       SUM(Bill) over (partition by accountNumber) as account_total
FROM Table1
order by AccountNumber, BillDate;

Here is an SQLFiddle: http://sqlfiddle.com/#!15/2c35e/1

You can even add a running sum, by adding:

sum(bill) over (partition by account_number order by bill_date) as sum_to_date

which will give you the total up to the current's row date.

Binary releases contain computer readable version of the application, meaning it is compiled. Source releases contain human readable version of the application, meaning it has to be compiled before it can be used.

Here's a couple of extension methods I've jury-rigged together to convert IQueryables and IEnumerables from one type to another (i.e. DTO). It's mainly used to convert from a larger type (i.e. the type of the row in the database that has unneeded fields) to a smaller one.

The positive sides of this approach are:

• it requires almost no code to use - a simple call to .Transform<DtoType>() is all you need
• it works just like .Select(s=>new{...}) i.e. when used with IQueryable it produces the optimal SQL code, excluding Type1 fields that DtoType doesn't have.

LinqHelper.cs:

public static IQueryable<TResult> Transform<TResult>(this IQueryable source)
{
    var resultType = typeof(TResult);
    var resultProperties = resultType.GetProperties().Where(p => p.CanWrite);

    ParameterExpression s = Expression.Parameter(source.ElementType, "s");

    var memberBindings =
        resultProperties.Select(p =>
            Expression.Bind(typeof(TResult).GetMember(p.Name)[0], Expression.Property(s, p.Name))).OfType<MemberBinding>();

    Expression memberInit = Expression.MemberInit(
        Expression.New(typeof(TResult)),
        memberBindings
        );

    var memberInitLambda = Expression.Lambda(memberInit, s);

    var typeArgs = new[]
        {
            source.ElementType, 
            memberInit.Type
        };

    var mc = Expression.Call(typeof(Queryable), "Select", typeArgs, source.Expression, memberInitLambda);

    var query = source.Provider.CreateQuery<TResult>(mc);

    return query;
}

public static IEnumerable<TResult> Transform<TResult>(this IEnumerable source)
{
    return source.AsQueryable().Transform<TResult>();
}

This is not an easy one. I've come up with a Script solution. (I don't think this can be done using pure CSS)

the HTML stays the same as you posted, the CSS changes a little bit, JQuery code added.

Working Fiddle Tested on: IE10, IE9, IE8, FF, Chrome

BTW: if you have unique elements, why don't you use id's instead of classes? I think it gives a better selector performance.

Explanation of how it works: inner-container will span the entire space of the outer-container (so basically, he's not needed) but I left him there, so you wont need to change you DOM.

the table-header is relatively positioned, without a scroll (overflow: hidden), we will handle his scroll later.

the table-body have to span the rest of the inner-container height, so I used a script to determine what height to fix him. (it changes dynamically when you re-size the window) without a fixed height, the scroll wont appear, because the div will just grow large instead.. notice that this part can be done without script, if you fix the header height and use CSS3 (as shown in the end of the answer)

now it's just a matter of moving the header along with the body each time we scroll. this is done by a function assigned to the scroll event.

CSS (some of it was copied from your style)

*
{
    padding: 0;
    margin: 0;
}

body
{
    height: 100%;
    width: 100%;
}
table
{
    border-collapse: collapse; /* make simple 1px lines borders if border defined */
}
.outer-container
{
    background-color: #ccc;
    position: absolute;
    top:0;
    left: 0;
    right: 300px;
    bottom: 40px;
}

.inner-container
{
    height: 100%;
    overflow: hidden;
}

.table-header
{
    position: relative;
}
.table-body
{
    overflow: auto;
}

.header-cell
{
    background-color: yellow;
    text-align: left;
    height: 40px;
}
.body-cell 
{
    background-color: blue;
    text-align: left;
}
.col1, .col3, .col4, .col5
{
    width:120px;
    min-width: 120px;
}
.col2
{
    min-width: 300px;
}

JQuery

$(document).ready(function () {
    setTableBody();
    $(window).resize(setTableBody);
    $(".table-body").scroll(function ()
    {
        $(".table-header").offset({ left: -1*this.scrollLeft });
    });
});

function setTableBody()
{
    $(".table-body").height($(".inner-container").height() - $(".table-header").height());
}

If you don't care about fixing the header height (I saw that you fixed the cell's height in your CSS), some of the Script can be skiped if you use CSS3 :Shorter Fiddle (this will not work on IE8)

In Python 3.8+ you can do

import hashlib

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    while chunk := f.read(8192):
        file_hash.update(chunk)

print(file_hash.digest())
print(file_hash.hexdigest())  # to get a printable str instead of bytes

On Python 3.7 and below:

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    chunk = f.read(8192)
    while chunk:
        file_hash.update(chunk)
        chunk = f.read(8192)

print(file_hash.hexdigest())

This reads the file 8192 (or 2¹³) bytes at a time instead of all at once with f.read() to use less memory.

Consider using hashlib.blake2b instead of md5 (just replace md5 with blake2b in the above snippets). It's cryptographically secure and faster than MD5.

I found this very annoying bug while converting EmployeeID values with ISNUMERIC:

SELECT DISTINCT [EmployeeID],
ISNUMERIC(ISNULL([EmployeeID], '')) AS [IsNumericResult],

CASE WHEN COALESCE(NULLIF(tmpImport.[EmployeeID], ''), 'Z')
    LIKE '%[^0-9]%' THEN 'NonNumeric' ELSE 'Numeric'
END AS [IsDigitsResult]
FROM [MyTable]

This returns:

EmployeeID IsNumericResult MyCustomResult
---------- --------------- --------------
           0               NonNumeric
00000000c  0               NonNumeric
00D026858  1               NonNumeric

(3 row(s) affected)

Hope this helps!

Your code was compiled with Java Version 1.8 while it is being executed with Java Version 1.7 or below.

In your case it seems that two different Java installations are used, the newer to compile and the older to execute your code.

Try recompiling your code with Java 1.7 or upgrade your Java Plugin.

<input type="text" id="txtCode" name="name" class="text_cs">

and js:

<script type="text/javascript">
$('.text_cs').on('change', function () {
var pid = $(this).val();
console.log("Value text: " + pid);
});
</script>

I do not believe that you can make a background image overflow its div. Images placed in Image tags can overflow their parent div, but background images are limited by the div for which they are the background.

you can use the each function:

var a = {};
a['alfa'] = 0;
a['beta'] = 1;
$.each(a, function(key, value) {
      alert(key)
});

it has several nice shortcuts/tricks: check the gory details here

If your request is sent by HTTPS you will have an extra server variable named 'HTTPS'

There is the data.table approach for an inner join, which is very time and memory efficient (and necessary for some larger data.frames):

library(data.table)

dt1 <- data.table(df1, key = "CustomerId") 
dt2 <- data.table(df2, key = "CustomerId")

joined.dt1.dt.2 <- dt1[dt2]

merge also works on data.tables (as it is generic and calls merge.data.table)

merge(dt1, dt2)

data.table documented on stackoverflow:
How to do a data.table merge operation
Translating SQL joins on foreign keys to R data.table syntax
Efficient alternatives to merge for larger data.frames R
How to do a basic left outer join with data.table in R?

Yet another option is the join function found in the plyr package

library(plyr)

join(df1, df2,
     type = "inner")

#   CustomerId Product   State
# 1          2 Toaster Alabama
# 2          4   Radio Alabama
# 3          6   Radio    Ohio

Options for type: inner, left, right, full.

From ?join: Unlike merge, [join] preserves the order of x no matter what join type is used.

You can use Bash for that:

while read -a cols; do echo ${cols[@]:0:1} ${cols[@]:1,-1}; done < file.txt

As the other answers have mentioned, the int operation will crash if the string input is not convertible to an int (such as a float or characters). What you can do is use a little helper method to try and interpret the string for you:

def interpret_string(s):
    if not isinstance(s, basestring):
        return str(s)
    if s.isdigit():
        return int(s)
    try:
        return float(s)
    except ValueError:
        return s

So it will take a string and try to convert it to int, then float, and otherwise return string. This is more just a general example of looking at the convertible types. It would be an error for your value to come back out of that function still being a string, which you would then want to report to the user and ask for new input.

Maybe a variation that returns None if its neither float nor int:

def interpret_string(s):
    if not isinstance(s, basestring):
        return None
    if s.isdigit():
        return int(s)
    try:
        return float(s)
    except ValueError:
        return None

val=raw_input("> ")
how_much=interpret_string(val)
if how_much is None:
    # ask for more input? Error?

I used the following in my own program.

Process.Start("http://www.google.com/etc/etc/test.txt")

It's a bit basic, but it does the job for me.

I am pretty sure it won't be possible with older versions of IE. Before the accept-charset attribute was devised, there was no way for form elements to specify which character encoding they accepted, and the best that browsers could do is assume the encoding of the page the form is in will do.

It is a bit sad that you need to know which encoding was used -- nowadays we would expect our web frameworks to take care of such details invisibly and expose the text data to the application as Unicode strings, already decoded...

getUserRootFolder() {
  return process.env.HOME || process.env.HOMEPATH || process.env.USERPROFILE;
}

Setting the image using picture.ImageLocation() works fine, but you are using a relative path. Check your path against the location of the .exe after it is built.

For example, if your .exe is located at:

<project folder>/bin/Debug/app.exe

The image would have to be at:

<project folder>/bin/Image/1.jpg

Of course, you could just set the image at design-time (the Image property on the PictureBox property sheet).

If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory to Copy if newer.

At this point the image file will be copied when you build the application and you can use

picture.ImageLocation = @"Image\1.jpg"; 

Jano's answer is the easiest way to find it.. another way would be if you click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column...

Actually, you are looking for the AJAX CALL, in which you will replace the URL parameter value with the link of the JSON file to get the JSON values.

$.ajax({
    url: "File.json", //the path of the file is replaced by File.json
    dataType: "json",
    success: function (response) {
        console.log(response); //it will return the json array
    }
});

var Str_txt = '{"theTeam":[{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"3","status":"member"}]}';

If you want to add at last position then use this:

var parse_obj = JSON.parse(Str_txt);
parse_obj['theTeam'].push({"teamId":"4","status":"pending"});
Str_txt = JSON.stringify(parse_obj);
Output //"{"theTeam":[{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"3","status":"member"},{"teamId":"4","status":"pending"}]}"

If you want to add at first position then use the following code:

var parse_obj = JSON.parse(Str_txt);
parse_obj['theTeam'].unshift({"teamId":"4","status":"pending"});
Str_txt = JSON.stringify(parse_obj);
Output //"{"theTeam":[{"teamId":"4","status":"pending"},{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"3","status":"member"}]}"

Anyone who wants to add at a certain position of an array try this:

parse_obj['theTeam'].splice(2, 0, {"teamId":"4","status":"pending"});
Output //"{"theTeam":[{"teamId":"1","status":"pending"},{"teamId":"2","status":"member"},{"teamId":"4","status":"pending"},{"teamId":"3","status":"member"}]}"

Above code block adds an element after the second element.

There are two ways:

1. Use the axes methods of the subplot object (e.g. ax.set_xticks and ax.set_xticklabels) or
2. Use plt.sca to set the current axes for the pyplot state machine (i.e. the plt interface).

As an example (this also illustrates using setp to change the properties of all of the subplots):

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=3, ncols=4)

# Set the ticks and ticklabels for all axes
plt.setp(axes, xticks=[0.1, 0.5, 0.9], xticklabels=['a', 'b', 'c'],
        yticks=[1, 2, 3])

# Use the pyplot interface to change just one subplot...
plt.sca(axes[1, 1])
plt.xticks(range(3), ['A', 'Big', 'Cat'], color='red')

fig.tight_layout()
plt.show()

I discovered that FF triggers the focus event for iframe.contentWindow but not for iframe.contentWindow.document. Chrome for example can handle both cases. so, I just needed to bind my event handlers to iframe.contentWindow in order to get things working. Maybe this helps somebody ...

Question: How can I open the href in the new window or tab with jQuery?

var url = $(this).attr('href').attr('target','_blank');

As of October 2014:

For latest remote version:

npm view <module_name> version  

Note, version is singular.

If you'd like to see all available (remote) versions, then do:

npm view <module_name> versions

Note, versions is plural. This will give you the full listing of versions to choose from.

To get the version you actually have locally you could use:

npm list --depth=0 | grep <module_name>

Note, even with package.json declaring your versions, the installed version might actually differ slightly - for instance if tilda was used in the version declaration

Should work across NPM versions 1.3.x, 1.4.x, 2.x and 3.x

The easiest and the most correct (and legal) way is to use graph api.

Just perform the request: http://graph.facebook.com/4

which returns

{
   "id": "4",
   "name": "Mark Zuckerberg",
   "first_name": "Mark",
   "last_name": "Zuckerberg",
   "link": "http://www.facebook.com/zuck",
   "username": "zuck",
   "gender": "male",
   "locale": "en_US"
}

and take the link key.

You can also reduce the traffic by using fields parameter: http://graph.facebook.com/4?fields=link to get only what you need:

{
   "link": "http://www.facebook.com/zuck",
   "id": "4"
}

Here is my recursive approach:

function visit(object) {
    if (isIterable(object)) {
        forEachIn(object, function (accessor, child) {
            visit(child);
        });
    }
    else {
        var value = object;
        console.log(value);
    }
}

function forEachIn(iterable, functionRef) {
    for (var accessor in iterable) {
        functionRef(accessor, iterable[accessor]);
    }
}

function isIterable(element) {
    return isArray(element) || isObject(element);
}

function isArray(element) {
    return element.constructor == Array;
}

function isObject(element) {
    return element.constructor == Object;
}

I use this:

char uppercaseChar = (char) ((int)(Math.random()*100)%26+65);

char lowercaseChar = (char) ((int)(Math.random()*1000)%26+97);

Note if you are using https.request do not directly use the body from res.on('data',... This will fail if you have a large data coming in chunks. So you need to concatenate all the data and then process the response in res.on('end'. Example -

  var options = {
    hostname: "www.google.com",
    port: 443,
    path: "/upload",
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Content-Length': Buffer.byteLength(post_data)
    }
  };

  //change to http for local testing
  var req = https.request(options, function (res) {
    res.setEncoding('utf8');

    var body = '';

    res.on('data', function (chunk) {
      body = body + chunk;
    });

    res.on('end',function(){
      console.log("Body :" + body);
      if (res.statusCode != 200) {
        callback("Api call failed with response code " + res.statusCode);
      } else {
        callback(null);
      }
    });

  });

  req.on('error', function (e) {
    console.log("Error : " + e.message);
    callback(e);
  });

  // write data to request body
  req.write(post_data);
  req.end();

Canvas text support is actually pretty good - you can control font, size, color, horizontal alignment, vertical alignment, and you can also get text metrics to get the text width in pixels. In addition, you can also use canvas transforms to rotate, stretch and even invert text.

No. While the definition from w3c for HTML 4 doesn't seem to explicitly cover your question, the definition of the name and id attribute says no spaces in the identifier:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

I found that:

git log --reverse

shows commits from start.

If you are interested in the indexes, the best choice is np.argsort(a)

a = np.random.randint(0, 100, 10)
sorted_idx = np.argsort(a)

With GNU Parallel you can do:

cat file | parallel 'foo {}; foo2 {}; foo3 {}'

This will run one job on each cpu core. To run 50 do:

cat file | parallel -j 50 'foo {}; foo2 {}; foo3 {}'

Unfortunately, you need to manually construct the query parameters, because as far as I know, there is no built-in bind method for binding a list to an IN clause, similar to Hibernate's setParameterList(). However, you can accomplish the same with the following:

Python 3:

args=['A', 'C']
sql='SELECT fooid FROM foo WHERE bar IN (%s)' 
in_p=', '.join(list(map(lambda x: '%s', args)))
sql = sql % in_p
cursor.execute(sql, args)

Python 2:

args=['A', 'C']
sql='SELECT fooid FROM foo WHERE bar IN (%s)' 
in_p=', '.join(map(lambda x: '%s', args))
sql = sql % in_p
cursor.execute(sql, args)

I had to do something similar but I was generating a Date object so I ended up making a function like this:

function convertTo24Hour(time) {
    var hours = parseInt(time.substr(0, 2));
    if(time.indexOf('am') != -1 && hours == 12) {
        time = time.replace('12', '0');
    }
    if(time.indexOf('pm')  != -1 && hours < 12) {
        time = time.replace(hours, (hours + 12));
    }
    return time.replace(/(am|pm)/, '');
}

I think this reads a little easier. You feed a string in the format h:mm am/pm.

    var time = convertTo24Hour($("#starttime").val().toLowerCase());
    var date = new Date($("#startday").val() + ' ' + time);

Examples:

        $("#startday").val('7/10/2013');

        $("#starttime").val('12:00am');
        new Date($("#startday").val() + ' ' + convertTo24Hour($("#starttime").val().toLowerCase()));
        Wed Jul 10 2013 00:00:00 GMT-0700 (PDT)

        $("#starttime").val('12:00pm');
        new Date($("#startday").val() + ' ' + convertTo24Hour($("#starttime").val().toLowerCase()));
        Wed Jul 10 2013 12:00:00 GMT-0700 (PDT)

        $("#starttime").val('1:00am');
        new Date($("#startday").val() + ' ' + convertTo24Hour($("#starttime").val().toLowerCase()));
        Wed Jul 10 2013 01:00:00 GMT-0700 (PDT)

        $("#starttime").val('12:12am');
        new Date($("#startday").val() + ' ' + convertTo24Hour($("#starttime").val().toLowerCase()));
        Wed Jul 10 2013 00:12:00 GMT-0700 (PDT)

        $("#starttime").val('3:12am');
        new Date($("#startday").val() + ' ' + convertTo24Hour($("#starttime").val().toLowerCase()));
        Wed Jul 10 2013 03:12:00 GMT-0700 (PDT)

        $("#starttime").val('9:12pm');
        new Date($("#startday").val() + ' ' + convertTo24Hour($("#starttime").val().toLowerCase()));
        Wed Jul 10 2013 21:12:00 GMT-0700 (PDT)

This is a limit of the C++ compiler. If you put the function in the header, all the cpp files where it can be inlined can see the "source" of your function and the inlining can be done by the compiler. Otherwhise the inlining would have to be done by the linker (each cpp file is compiled in an obj file separately). The problem is that it would be much more difficult to do it in the linker. A similar problem exists with "template" classes/functions. They need to be instantiated by the compiler, because the linker would have problem instantiating (creating a specialized version of) them. Some newer compiler/linker can do a "two pass" compilation/linking where the compiler does a first pass, then the linker does its work and call the compiler to resolve unresolved things (inline/templates...)

Since JVM arguments are eventually passed to your java program as system variables, you can use this code at the beginning of your execution point to edit the property and have log4j read the property you just set in system properties

try {
        System.setProperty("log4j.configuration", new File(System.getProperty("user.dir")+File.separator+"conf"+File.separator+"log4j.properties").toURI().toURL().toString());
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }

One method is parseInt(String). It returns a primitive int:

String number = "10";
int result = Integer.parseInt(number);
System.out.println(result);

The second method is valueOf(String), and it returns a new Integer() object:

String number = "10";
Integer result = Integer.valueOf(number);
System.out.println(result);

I found something that worked for me. When I wrote my comment to the OP I had failed to check the system config file:

git config --system -l

shows a

credential.helper=!github --credentials

line. I unset it with

git config --system --unset credential.helper

and now the credentials are forgotten.

In case you are using Silex add the Symfony Asset as a dependency:

composer require symfony/asset

Then you may register Asset Service Provider:

$app->register(new Silex\Provider\AssetServiceProvider(), array(
    'assets.version' => 'v1',
    'assets.version_format' => '%s?version=%s',
    'assets.named_packages' => array(
        'css' => array(
            'version' => 'css2',
            'base_path' => __DIR__.'/../public_html/resources/css'
        ),
        'images' => array(
            'base_urls' => array(
                'https://img.example.com'
            )
        ),
    ),
));

Then in your Twig template file in head section:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    {% block head %}
    <link rel="stylesheet" href="{{ asset('style.css') }}" />
    {% endblock %}
</head>
<body>

</body>
</html>

You can use the built-in FolderBrowserDialog class for this. Don't mind that it's in the System.Windows.Forms namespace.

using (var dialog = new System.Windows.Forms.FolderBrowserDialog())
{
    System.Windows.Forms.DialogResult result = dialog.ShowDialog();
}

If you want the window to be modal over some WPF window, see the question How to use a FolderBrowserDialog from a WPF application.

EDIT: If you want something a bit more fancy than the plain, ugly Windows Forms FolderBrowserDialog, there are some alternatives that allow you to use the Vista dialog instead:

• Third-party libraries, such as Ookii dialogs (.NET 4.5+)

• The Windows API Code Pack-Shell:

    using Microsoft.WindowsAPICodePack.Dialogs;
  
    ...
  
    var dialog = new CommonOpenFileDialog();
    dialog.IsFolderPicker = true;
    CommonFileDialogResult result = dialog.ShowDialog();
  

  Note that this dialog is not available on operating systems older than Windows Vista, so be sure to check CommonFileDialog.IsPlatformSupported first.

It seems to be a known issue. You can instruct m2e to ignore this.

Option 1: pom.xml

Add the following inside your <build/> tag:

<pluginManagement>
<plugins>
    <!-- Ignore/Execute plugin execution -->
    <plugin>
        <groupId>org.eclipse.m2e</groupId>
        <artifactId>lifecycle-mapping</artifactId>
        <version>1.0.0</version>
        <configuration>
            <lifecycleMappingMetadata>
                <pluginExecutions>

                            </goals>
                        </pluginExecutionFilter>
                        <action>
                            <ignore />
                        </action>
                    </pluginExecution>
                </pluginExecutions>
            </lifecycleMappingMetadata>

Option 2: Global Eclipse Override

To avoid changing your POM files, the ignore override can be applied to the whole workspace via Eclipse settings.

Save this file somewhere on the disk: https://gist.github.com/maksimov/8906462

In Eclipse/Preferences/Maven/Lifecycle Mappings browse to this file and click OK:

git reset --hard

Stackoverflow uses such function to determine the age of a user.

Calculate age in C#

The given answer is

DateTime now = DateTime.Today;
int age = now.Year - bday.Year;
if (now < bday.AddYears(age)) age--;

So your helper method would look like

public static string Age(this HtmlHelper helper, DateTime birthday)
{
    DateTime now = DateTime.Today;
    int age = now.Year - birthday.Year;
    if (now < birthday.AddYears(age)) age--;

    return age.ToString();
}

Today, I use a different version of this function to include a date of reference. This allow me to get the age of someone at a future date or in the past. This is used for our reservation system, where the age in the future is needed.

public static int GetAge(DateTime reference, DateTime birthday)
{
    int age = reference.Year - birthday.Year;
    if (reference < birthday.AddYears(age)) age--;

    return age;
}

int count = 100;
int total = 0;
int[] numbers = new int[count];
for (int i=0; count>i; i++) {
    numbers[i] = i+1;
    total += i+1;
}
// done

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

This should work

<option *ngFor="let title of titleArray" 
    [value]="title.Value" 
    [attr.selected]="passenger.Title==title.Text ? true : null">
  {{title.Text}}
</option>

I'm not sure the attr. part is necessary.

There's a few ways, this is one:

window.history.go(-1);

From your description I assume you are on windows machine and your home is abc

So Now : Cause

When you run this command

keytool -genkey -alias tomcat -keyalg RSA

because you are not specifying an explicit keystore it will try to generate (and in your case as you are getting exception so to update) keystore C:\users\abc>.keystore and of course you need to provide old password for .keystore while I believe you are providing your version (a new one).

Solution

1. Either delete .keystore from C:\users\abc> location and try the command

2. or try following command which will create a new xyzkeystore:

   keytool -genkey -keystore xyzkeystore -alias tomcat -keyalg RSA

Note: -genkey is old now rather use -genkeypair althought both work equally.

You're looking for the setInterval function, which runs a function every x milliseconds.

For example:

var start = new Date;

setInterval(function() {
    $('.Timer').text((new Date - start) / 1000 + " Seconds");
}, 1000);

"Premature optimization is the root of all evil."

With that firmly in mind, let's do this! Once your apps hit a certain point, denormalizing data is very common. Done correctly, it can save numerous expensive database lookups at the cost of a little more housekeeping.

To return a list of friend names we'll need to create a custom Django Field class that will return a list when accessed.

David Cramer posted a guide to creating a SeperatedValueField on his blog. Here is the code:

from django.db import models

class SeparatedValuesField(models.TextField):
    __metaclass__ = models.SubfieldBase

    def __init__(self, *args, **kwargs):
        self.token = kwargs.pop('token', ',')
        super(SeparatedValuesField, self).__init__(*args, **kwargs)

    def to_python(self, value):
        if not value: return
        if isinstance(value, list):
            return value
        return value.split(self.token)

    def get_db_prep_value(self, value):
        if not value: return
        assert(isinstance(value, list) or isinstance(value, tuple))
        return self.token.join([unicode(s) for s in value])

    def value_to_string(self, obj):
        value = self._get_val_from_obj(obj)
        return self.get_db_prep_value(value)

The logic of this code deals with serializing and deserializing values from the database to Python and vice versa. Now you can easily import and use our custom field in the model class:

from django.db import models
from custom.fields import SeparatedValuesField 

class Person(models.Model):
    name = models.CharField(max_length=64)
    friends = SeparatedValuesField()

Architecture:
Structural design work at higher levels of abstraction which realize technically significant requirements into the system. The architecture lays down foundation for further design.

Design:
The art of filling in what the architecture does not through an iterative process at each layer of abstraction.

If your output is delimited by tabs a quick solution would be to use the tabs command to adjust the size of your tabs.

tabs 20
keys | awk '{ print $1"\t\t" $2 }'

If you need direct access:

WScript.Arguments.Item(0)
WScript.Arguments.Item(1)
...

(For anyone still interested in the topic.)

Consider this (includes even usage of statements' return values in further statements within the "multiline" lambda, although it's ugly to the point of vomiting ;-)

>>> def foo(arg):
...     result = arg * 2;
...     print "foo(" + str(arg) + ") called: " + str(result);
...     return result;
...
>>> f = lambda a, b, state=[]: [
...     state.append(foo(a)),
...     state.append(foo(b)),
...     state.append(foo(state[0] + state[1])),
...     state[-1]
... ][-1];
>>> f(1, 2);
foo(1) called: 2
foo(2) called: 4
foo(6) called: 12
12

If your solution contains two projects interacting with each other and both using one same reference, And if version of respective reference is different in both projects; Then also such errors occurred. Keep updating all references to latest one.

function range(j, k) { 
    return Array
        .apply(null, Array((k - j) + 1))
        .map(function(_, n){ return n + j; }); 
}

this is roughly equivalent to

function range(j, k) { 
    var targetLength = (k - j) + 1;
    var a = Array(targetLength);
    var b = Array.apply(null, a);
    var c = b.map(function(_, n){ return n + j; });
    return c;
}

breaking it down:

var targetLength = (k - j) + 1;

var a = Array(targetLength);

this creates a sparse matrix of the correct nominal length. Now the problem with a sparse matrix is that although it has the correct nominal length, it has no actual elements, so, for

j = 7, k = 13

console.log(a);

gives us

Array [ <7 empty slots> ]

Then

var b = Array.apply(null, a);

passes the sparse matrix as an argument list to the Array constructor, which produces a dense matrix of (actual) length targetLength, where all elements have undefined value. The first argument is the 'this' value for the the array constructor function execution context, and plays no role here, and so is null.

So now,

 console.log(b);

yields

 Array [ undefined, undefined, undefined, undefined, undefined, undefined, undefined ]

finally

var c = b.map(function(_, n){ return n + j; });

makes use of the fact that the Array.map function passes: 1. the value of the current element and 2. the index of the current element, to the map delegate/callback. The first argument is discarded, while the second can then be used to set the correct sequence value, after adjusting for the start offset.

So then

console.log(c);

yields

 Array [ 7, 8, 9, 10, 11, 12, 13 ]

This works for me

import seaborn as sns
import matplotlib.pyplot as plt
%matplotlib inline

sns.factorplot(x='holiday',data=data,kind='count',size=5,aspect=1)
plt.savefig('holiday-vs-count.png')

to_timestamp()

You need to use to_timestamp() to convert your string to a proper timestamp value:

to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

to_date()

If your column is of type DATE (which also supports seconds), you need to use to_date()

to_date('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

Example

To get this into a where condition use the following:

select * 
from TableA 
where startdate >= to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
  and startdate <= to_timestamp('12-01-2012 21:25:33', 'dd-mm-yyyy hh24:mi:ss')

Note

You never need to use to_timestamp() on a column that is of type timestamp.

Your error

InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

appears because you must call setRequestHeader after calling open. Simply move your setRequestHeader line below your open line (but before send):

xmlhttp.send(formData);

I found out that the image that you are specify with the og:image, has to actually be present in the HTML page inside an image tag.

the thumbnail appeared for me only after i added an image tag for the image. it was commented out. but worked.

I just came across this so I am sharing here. Here is the option

https://eonasdan.github.io/bootstrap-datetimepicker/Options/#ignorereadonly

Here is the code.

HTML

<br/>
<!-- padding for jsfiddle -->
<div class="input-group date" id="arrival_date_div">
  <input type="text" class="form-control" id="arrival_date" name="arrival_date" required readonly="readonly" />
  <span class="input-group-addon">
    <span class="glyphicon-calendar glyphicon"></span>
  </span>
</div>

JS

$('#arrival_date_div').datetimepicker({
  format: "YYYY-MM-DD",
  ignoreReadonly: true
});

Here is the fiddle:

My version of bootstrap-datetimepicker.js is 4.17.45

there's a bootstrap function to change the color of table header called thead-dark for dark background of table header and thead-light for light background of table header. Your code will look like this after using this function.

<table class="table">
    <tr class="thead-danger">
        <!-- here I used dark table headre -->
        <th>
            @Html.DisplayNameFor(model => model.name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.checkBox1)
        </th>
        <th></th>
    </tr>

The best option is create a directive and wrap the slider features there. The secret is use $timeout, the jquery code will be called only when DOM is ready.

angular.module('app')
.directive('my-slider', 
    ['$timeout', function($timeout) {
        return {
            restrict:'E',
            scope: true,
            template: '<div id="{{ id }}"></div>',
            link: function($scope) {
                $scope.id = String(Math.random()).substr(2, 8);

                $timeout(function() {
                    angular.element('#'+$scope.id).slider();                    
                });
            }
        };
    }]
);

Use a Linux Live cd/usb and boot an that to be able to directly connect to your wifi hardware or use linux as the main OS with direct access to the wifi card and then use windows as a guest os, I know that this maybe not the ideal way but it will work.

Make a new folder inside htdocs and access it in browser.Like this or this. Always start Apache when you start working or check whether it has started (in Control panel of xampp).

This can also be due to missing __init__.py file from the directory. Say if you create a new directory in django for seperating the unit tests into multiple files and place them in one directory then you also have to create the __init__.py file beside all the other files in new created test directory. otherwise it can give error like Traceback (most recent call last): File "C:\Users\USERNAME\AppData\Local\Programs\Python\Python35\Lib\unittest\loader.py",line 153, in loadTestsFromName module = __import__(module_name) ImportError: bad magic number in 'APPNAME.tests': b'\x03\xf3\r\n'

Had this issue with ES6 and TypeORM while trying to pass .where("order.id IN (:orders)", { orders }), where orders was a comma separated string of numbers. When I converted to a template literal, the problem was resolved.

.where(`order.id IN (${orders})`);

Most of the roles you see were defined as part of ARIA 1.0, and then later incorporated into HTML via supporting specs like HTML-AAM. Some of the new HTML5 elements (dialog, main, etc.) are even based on the original ARIA roles.

http://www.w3.org/TR/wai-aria/

There are a few primary reasons to use roles in addition to your native semantic element.

Reason #1. Overriding the role where no host language element is appropriate or, for various reasons, a less semantically appropriate element was used.

In this example, a link was used, even though the resulting functionality is more button-like than a navigation link.

<a href="#" role="button" aria-label="Delete item 1">Delete</a>
<!-- Note: href="#" is just a shorthand here, not a recommended technique. Use progressive enhancement when possible. -->

Screen readers users will hear this as a button (as opposed to a link), and you can use a CSS attribute selector to avoid class-itis and div-itis.

[role="button"] {
  /* style these as buttons w/o relying on a .button class */
}

[Update 7 years later: removed the * selector to make some commenters happy, since the old browser quirk that required universal selector on attribute selectors is unnecessary in 2020.]

Reason #2. Backing up a native element's role, to support browsers that implemented the ARIA role but haven't yet implemented the native element's role.

For example, the "main" role has been supported in browsers for many years, but it's a relatively recent addition to HTML5, so many browsers don't yet support the semantic for <main>.

<main role="main">…</main>

This is technically redundant, but helps some users and doesn't harm any. In a few years, this technique will likely become unnecessary for main.

Reason #3. Update 7 years later (2020): As at least one commenter pointed out, this is now very useful for custom elements, and some spec work is underway to define the default accessibility role of a web component. Even if/once that API is standardized, there may be need to override the default role of a component.

Note/Reply

You also wrote:

I see some people make up their own. Is that allowed or a correct use of the role attribute?

That's an allowed use of the attribute unless a real role is not included. Browsers will apply the first recognized role in the token list.

<span role="foo link note bar">...</a>

Out of the list, only link and note are valid roles, and so the link role will be applied in the platform accessibility API because it comes first. If you use custom roles, make sure they don't conflict with any defined role in ARIA or the host language you're using (HTML, SVG, MathML, etc.)

Does the user you're executing this script under even see that table??

select top 1 * from products

Do you get any output for this??

If yes: does this user have the permission to modify the table, i.e. execute DDL scripts like ALTER TABLE etc.? Typically, regular users don't have this elevated permissions.

There is a trick to push postgres to prefer a seqscan adding a OFFSET 0 in the subquery

This is handy for optimizing requests linking big/huge tables when all you need is only the n first/last elements.

Lets say you are looking for first/last 20 elements involving multiple tables having 100k (or more) entries, no point building/linking up all the query over all the data when what you'll be looking for is in the first 100 or 1000 entries. In this scenario for example, it turns out to be over 10x faster to do a sequential scan.

see How can I prevent Postgres from inlining a subquery?

Firstly, run the command below:

apt-get update && apt-get install procps

and then run:

Cron utility is an effective way to schedule a routine background job at a specific time and/or day on an on-going basis.

Linux Crontab Format

MIN HOUR DOM MON DOW CMD

Example::Scheduling a Job For a Specific Time

The basic usage of cron is to execute a job in a specific time as shown below. This will execute the Full backup shell script (full-backup) on 10th June 08:30 AM.

Please note that the time field uses 24 hours format. So, for 8 AM use 8, and for 8 PM use 20.

30 08 10 06 * /home/yourname/full-backup

• 30 – 30th Minute
• 08 – 08 AM
• 10 – 10th Day
• 06 – 6th Month (June)
• *– Every day of the week

In your case, for 2.30PM,

30 14 * * * YOURCMD

1. 30 – 30th Minute
2. 14 – 2PM
3. *– Every day
4. *– Every month
5. *– Every day of the week

There's more than one way to skin this problem so here's my solution:

1. Use Select() to convert the key-value pair to a string;
2. Convert to a list of strings;
3. Write out to the console using ForEach().

dict.Select(i => $"{i.Key}: {i.Value}").ToList().ForEach(Console.WriteLine);

 public List<Model> getAllData(Pageable pageable){
       List<Model> models= new ArrayList<>();
       modelRepository.findAllByOrderByIdDesc(pageable).forEach(models::add);
       return models;
   }

I know it's a bit late, but I just came across this post and wanted to mention that I don't really see way everybody wants to do it in a difficult way... The problem here is just that the book class takes twoside as default, so, as gromgull said, just pass oneside as argument and it's solved.

Could not add as comment because of size: Not sure if this is true, besides updating retention.ms and retention.bytes, but I noticed topic cleanup policy should be "delete" (default), if "compact", it is going to hold on to messages longer, i.e., if it is "compact", you have to specify delete.retention.ms also.

./bin/kafka-configs.sh --zookeeper localhost:2181 --describe --entity-name test-topic-3-100 --entity-type topics
Configs for topics:test-topic-3-100 are retention.ms=1000,delete.retention.ms=10000,cleanup.policy=delete,retention.bytes=1

Also had to monitor earliest/latest offsets should be same to confirm this successfully happened, can also check the du -h /tmp/kafka-logs/test-topic-3-100-*

./bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list "BROKER:9095" --topic test-topic-3-100 --time -1 | awk -F ":" '{sum += $3} END {print sum}' 26599762

./bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list "BROKER:9095" --topic test-topic-3-100 --time -2 | awk -F ":" '{sum += $3} END {print sum}' 26599762

The other problem is, you have to get current config first so you remember to revert after deletion is successful: ./bin/kafka-configs.sh --zookeeper localhost:2181 --describe --entity-name test-topic-3-100 --entity-type topics

             }

    } else if (drawable == null) {
        setAlpha(0f)
        setImageResource(resId)
        animate()
            .alpha(1f)
            .setDuration(duration)
    }
}

I could also just add that I knew everything about the syntax change between Python2.7 and Python3, and my code was correctly written as print("string") and even print(f"string")...

But after some time of debugging I realized that my bash script was calling python like:

python file_name.py

which had the effect of calling my python script by default using python2.7 which gave the error. So I changed my bash script to:

python3 file_name.py

which of coarse uses python3 to run the script which fixed the error.

You can easily implement clrscr() using simple for loop printing "\b".

Set oShell = CreateObject ("WScript.Shell") 
oShell.run "cmd.exe /C copy ""S:Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

var uniq = allvalues.GroupBy(x => x.Id).Select(y=>y.First()).Distinct();

Easy and simple

To keep the promise chain going, you can't use setTimeout() the way you did because you aren't returning a promise from the .then() handler - you're returning it from the setTimeout() callback which does you no good.

Instead, you can make a simple little delay function like this:

function delay(t, v) {
   return new Promise(function(resolve) { 
       setTimeout(resolve.bind(null, v), t)
   });
}

And, then use it like this:

getLinks('links.txt').then(function(links){
    let all_links = (JSON.parse(links));
    globalObj=all_links;

    return getLinks(globalObj["one"]+".txt");

}).then(function(topic){
    writeToBody(topic);
    // return a promise here that will be chained to prior promise
    return delay(1000).then(function() {
        return getLinks(globalObj["two"]+".txt");
    });
});

Here you're returning a promise from the .then() handler and thus it is chained appropriately.

You can also add a delay method to the Promise object and then directly use a .delay(x) method on your promises like this:

function delay(t, v) {_x000D_
   return new Promise(function(resolve) { _x000D_
       setTimeout(resolve.bind(null, v), t)_x000D_
   });_x000D_
}_x000D_
_x000D_
Promise.prototype.delay = function(t) {_x000D_
    return this.then(function(v) {_x000D_
        return delay(t, v);_x000D_
    });_x000D_
}_x000D_
_x000D_
_x000D_
Promise.resolve("hello").delay(500).then(function(v) {_x000D_
    console.log(v);_x000D_
});

Or, use the Bluebird promise library which already has the .delay() method built-in.

I have encountered this error on "an empty branch" on my local gitlab server. Some people mentioned that "you can not push for the first time on an empty branch". I tried to create a simple README file on the gitlab via my browser. Then everything fixed amazingly and the problem sorted out!! I mention that I was the master and the branch was not protected.

Do not create separate lists; create a list of lists:

results = []
with open('inputfile.txt') as inputfile:
    for line in inputfile:
        results.append(line.strip().split(','))

or better still, use the csv module:

import csv

results = []
with open('inputfile.txt', newline='') as inputfile:
    for row in csv.reader(inputfile):
        results.append(row)

Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.

Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append() just process that line right there.

Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:

import csv

with open('inputfile.txt', newline='') as inputfile:
    results = list(csv.reader(inputfile))

In addition to dumping the ordered list of keys alongside the dictionary, another low-tech solution, which has the advantage of being explicit, is to dump the (ordered) list of key-value pairs ordered_dict.items(); loading is a simple OrderedDict(<list of key-value pairs>). This handles an ordered dictionary despite the fact that JSON does not have this concept (JSON dictionaries have no order).

It is indeed nice to take advantage of the fact that json dumps the OrderedDict in the correct order. However, it is in general unnecessarily heavy and not necessarily meaningful to have to read all JSON dictionaries as an OrderedDict (through the object_pairs_hook argument), so an explicit conversion of only the dictionaries that must be ordered makes sense too.

I was having a similar problem. (No problems training with GradientDescent optimizer, but error raised when using to Adam Optimizer, or any other optimizer with its own variables)

Changing to an interactive session solved this problem for me.

sess = tf.Session()

into

sess = tf.InteractiveSession()

.abc, .xyz { margin-left: 20px; }

is what you are looking for.

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

You may use event handler serverclick as below

//cmdAction is the id of HTML button as below

<body>
    <form id="form1" runat="server">
        <button type="submit" id="cmdAction" text="Button1" runat="server">
            Button1
        </button>
    </form>
</body>

//cs code

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
                cmdAction.ServerClick += new EventHandler(submit_click);  
        }

        protected void submit_click(object sender, EventArgs e)
        {
            Response.Write("HTML Server Button Control");
        }
    }

Renderer has been deprecated in Angular 4.0.0-rc.1, read the update below

The angular2 way is to use listen or listenGlobal from Renderer

For example, if you want to add a click event to a Component, you have to use Renderer and ElementRef (this gives you as well the option to use ViewChild, or anything that retrieves the nativeElement)

constructor(elementRef: ElementRef, renderer: Renderer) {

    // Listen to click events in the component
    renderer.listen(elementRef.nativeElement, 'click', (event) => {
      // Do something with 'event'
    })
);

You can use listenGlobal that will give you access to document, body, etc.

renderer.listenGlobal('document', 'click', (event) => {
  // Do something with 'event'
});

Note that since beta.2 both listen and listenGlobal return a function to remove the listener (see breaking changes section from changelog for beta.2). This is to avoid memory leaks in big applications (see #6686).

So to remove the listener we added dynamically we must assign listen or listenGlobal to a variable that will hold the function returned, and then we execute it.

// listenFunc will hold the function returned by "renderer.listen"
listenFunc: Function;

// globalListenFunc will hold the function returned by "renderer.listenGlobal"
globalListenFunc: Function;

constructor(elementRef: ElementRef, renderer: Renderer) {
    
    // We cache the function "listen" returns
    this.listenFunc = renderer.listen(elementRef.nativeElement, 'click', (event) => {
        // Do something with 'event'
    });

    // We cache the function "listenGlobal" returns
    this.globalListenFunc = renderer.listenGlobal('document', 'click', (event) => {
        // Do something with 'event'
    });
}

ngOnDestroy() {
    // We execute both functions to remove the respectives listeners

    // Removes "listen" listener
    this.listenFunc();
    
    // Removs "listenGlobal" listener
    this.globalListenFunc();
}

Here's a plnkr with an example working. The example contains the usage of listen and listenGlobal.

Using RendererV2 with Angular 4.0.0-rc.1+ ^{_{(Renderer2 since 4.0.0-rc.3)}}

• 25/02/2017: Renderer has been deprecated, now we should use RendererV2 (see line below). See the commit.

• 10/03/2017: RendererV2 was renamed to Renderer2. See the breaking changes.

RendererV2 has no more listenGlobal function for global events (document, body, window). It only has a listen function which achieves both functionalities.

For reference, I'm copy & pasting the source code of the DOM Renderer implementation since it may change (yes, it's angular!).

listen(target: 'window'|'document'|'body'|any, event: string, callback: (event: any) => boolean):
      () => void {
    if (typeof target === 'string') {
      return <() => void>this.eventManager.addGlobalEventListener(
          target, event, decoratePreventDefault(callback));
    }
    return <() => void>this.eventManager.addEventListener(
               target, event, decoratePreventDefault(callback)) as() => void;
  }

As you can see, now it verifies if we're passing a string (document, body or window), in which case it will use an internal addGlobalEventListener function. In any other case, when we pass an element (nativeElement) it will use a simple addEventListener

To remove the listener it's the same as it was with Renderer in angular 2.x. listen returns a function, then call that function.

Example

// Add listeners
let global = this.renderer.listen('document', 'click', (evt) => {
  console.log('Clicking the document', evt);
})

let simple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
  console.log('Clicking the button', evt);
});

// Remove listeners
global();
simple();

plnkr with Angular 4.0.0-rc.1 using RendererV2

plnkr with Angular 4.0.0-rc.3 using Renderer2

You have to add attribute newline="\n" to open function like this:

with open('file.csv','w',newline="\n") as out:
    csv_out = csv.writer(out, delimiter =';')

You can use floating:

<div class="paragraphs">
  <div class="row">
    <div class="span4">
      <img style="float:left" src="../site/img/success32.png"/>
      <div class="content-heading"><h3>Experience &nbsp </h3></div>
      <p style="clear:both">Donec id elit non mi porta gravida at eget metus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui.</p>
    </div>
  </div>
</div>

If you want the following <p> to stay at the same line too, remove its

style="clear:both"

but then you should add

<div style="clear:both"></div>

after it.

sp_who2 will actually provide a list of connections for the database server, not a database. To view connections for a single database (YourDatabaseName in this example), you can use

DECLARE @AllConnections TABLE(
    SPID INT,
    Status VARCHAR(MAX),
    LOGIN VARCHAR(MAX),
    HostName VARCHAR(MAX),
    BlkBy VARCHAR(MAX),
    DBName VARCHAR(MAX),
    Command VARCHAR(MAX),
    CPUTime INT,
    DiskIO INT,
    LastBatch VARCHAR(MAX),
    ProgramName VARCHAR(MAX),
    SPID_1 INT,
    REQUESTID INT
)

INSERT INTO @AllConnections EXEC sp_who2

SELECT * FROM @AllConnections WHERE DBName = 'YourDatabaseName'

(Adapted from SQL Server: Filter output of sp_who2.)

Try opening Port 3306, and using that in the connection string not 8080.

I haven't worked much with phones, so I dont't know if this would work. But just from a html/javascript point of view, you could just open a different url depending on what the user's device is?

<a style="cursor: pointer;" onclick="myNavFunc()">Take me there!</a>

function myNavFunc(){
    // If it's an iPhone..
    if( (navigator.platform.indexOf("iPhone") != -1) 
        || (navigator.platform.indexOf("iPod") != -1)
        || (navigator.platform.indexOf("iPad") != -1))
         window.open("maps://www.google.com/maps/dir/?api=1&travelmode=driving&layer=traffic&destination=[YOUR_LAT],[YOUR_LNG]");
    else
         window.open("https://www.google.com/maps/dir/?api=1&travelmode=driving&layer=traffic&destination=[YOUR_LAT],[YOUR_LNG]");
}

This will

#myDiv
{
    cursor: pointer;
}

Since this is an open-ended question, I will just give you an idea of how I would go about implementing something like this myself.

<span class="inputname">
    Project Images:
    <a href="#" class="add_project_file">
        <img src="images/add_small.gif" border="0" />
    </a>
</span>

<ul class="project_images">
    <li><input name="upload_project_images[]" type="file" /></li>
</ul>

Wrapping the file inputs inside li elements allows to easily remove the parent of our 'remove' links when clicked. The jQuery to do so is close to what you have already:

// Add new input with associated 'remove' link when 'add' button is clicked.
$('.add_project_file').click(function(e) {
    e.preventDefault();

    $(".project_images").append(
        '<li>'
      + '<input name="upload_project_images[]" type="file" class="new_project_image" /> '
      + '<a href="#" class="remove_project_file" border="2"><img src="images/delete.gif" /></a>'
      + '</li>');
});

// Remove parent of 'remove' link when link is clicked.
$('.project_images').on('click', '.remove_project_file', function(e) {
    e.preventDefault();

    $(this).parent().remove();
});

string input = "Exemple of value between two string FirstString text I want to keep SecondString end of my string";
var match = Regex.Match(input, @"FirstString (.+?) SecondString ").Groups[1].Value;

Following Glens idea, here it goes another possibility. It would allow you to scroll inside the div, but would prevent the body to scroll with it, when the div scroll ends. However, it seems to accumulate too many preventDefault if you scroll too much, and then it creates a lag if you want to scroll up. Does anybody have a suggestion to fix that?

    $(".scrollInsideThisDiv").bind("mouseover",function(){
       var bodyTop = document.body.scrollTop;
       $('body').on({
           'mousewheel': function(e) {
           if (document.body.scrollTop == bodyTop) return;
           e.preventDefault();
           e.stopPropagation();
           }
       });
    });
    $(".scrollInsideThisDiv").bind("mouseleave",function(){
          $('body').unbind("mousewheel");
    });

Here's the code to do a nice smooth fade between two Activities..

Create a file called fadein.xml in res/anim

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
   android:interpolator="@android:anim/accelerate_interpolator"
   android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="2000" />

Create a file called fadeout.xml in res/anim

<?xml version="1.0" encoding="utf-8"?>

<alpha xmlns:android="http://schemas.android.com/apk/res/android"
   android:interpolator="@android:anim/accelerate_interpolator"
   android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="2000" />

If you want to fade from Activity A to Activity B, put the following in the onCreate() method for Activity B. Before setContentView() works for me.

overridePendingTransition(R.anim.fadein, R.anim.fadeout);

If the fades are too slow for you, change android:duration in the xml files above to something smaller.

add_Pbl <= to_stdlogicvector(to_bitvector(dato_cu(25 downto 2)) sll 1);
add_Pbl is a std_logic_vector of 24 bit
dato_cu is a std_logic_vector of 32 bit

First, you need to convert the std_logic_vector with to_bitvector() function because sll statement works with logic 1 and 0 bits.

• Percent encoding in the path section of a URL is expected to be decoded, but
• any + characters in the path component is expected to be treated literally.

To be explicit: + is only a special character in the query component.

https://tools.ietf.org/html/rfc3986

  var queryObj = {};
   if(url.split("?").length>0){
     var queryString = url.split("?")[1];
   }

now you have the query part in queryString

First replace will remove all the white spaces, second will replace all the '&' part with "," and finally the third replace will put ":" in place of '=' signs.

queryObj = JSON.parse('{"' + queryString.replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')

So let say you had a query like abc=123&efg=456. Now before parsing, your query is being converted into something like {"abc":"123","efg":"456"}. Now when you will parse this, it will give you your query in json object.

As an alternative to virtualenv, you can use anaconda.

On Linux, to create an environment with python 2.7:

conda create -n python2p7 python=2.7
source activate python2p7

To deactivate it, you do:

source deactivate

It is possible to install other package inside your environment.

Here's a simple pure JavaScript solution that works for a target Number (value for scrollTop), target DOM element, or some special String cases:

/**
 * target - target to scroll to (DOM element, scrollTop Number, 'top', or 'bottom'
 * containerEl - DOM element for the container with scrollbars
 */
var scrollToTarget = function(target, containerEl) {
    // Moved up here for readability:
    var isElement = target && target.nodeType === 1,
        isNumber = Object.prototype.toString.call(target) === '[object Number]';

    if (isElement) {
        containerEl.scrollTop = target.offsetTop;
    } else if (isNumber) {
        containerEl.scrollTop = target;
    } else if (target === 'bottom') {
        containerEl.scrollTop = containerEl.scrollHeight - containerEl.offsetHeight;
    } else if (target === 'top') {
        containerEl.scrollTop = 0;
    }
};

And here are some examples of usage:

// Scroll to the top
var scrollableDiv = document.getElementById('scrollable_div');
scrollToTarget('top', scrollableDiv);

or

// Scroll to 200px from the top
var scrollableDiv = document.getElementById('scrollable_div');
scrollToTarget(200, scrollableDiv);

or

// Scroll to targetElement
var scrollableDiv = document.getElementById('scrollable_div');
var targetElement= document.getElementById('target_element');
scrollToTarget(targetElement, scrollableDiv);

You can iterate over the row data

$('#button').click(function () {
    var ids = $.map(table.rows('.selected').data(), function (item) {
        return item[0]
    });
    console.log(ids)
    alert(table.rows('.selected').data().length + ' row(s) selected');
});

Demo: Fiddle

You can use tableToExcel.js to export table in excel file.

This works in a following way :

1). Include this CDN in your project/file

<script src="https://cdn.jsdelivr.net/gh/linways/[email protected]/dist/tableToExcel.js"></script>

2). Either Using JavaScript:

<button id="btnExport" onclick="exportReportToExcel(this)">EXPORT REPORT</button>

function exportReportToExcel() {
  let table = document.getElementsByTagName("table"); // you can use document.getElementById('tableId') as well by providing id to the table tag
  TableToExcel.convert(table[0], { // html code may contain multiple tables so here we are refering to 1st table tag
    name: `export.xlsx`, // fileName you could use any name
    sheet: {
      name: 'Sheet 1' // sheetName
    }
  });
}

3). Or by Using Jquery

<button id="btnExport">EXPORT REPORT</button>

$(document).ready(function(){
    $("#btnExport").click(function() {
        let table = document.getElementsByTagName("table");
        TableToExcel.convert(table[0], { // html code may contain multiple tables so here we are refering to 1st table tag
           name: `export.xlsx`, // fileName you could use any name
           sheet: {
              name: 'Sheet 1' // sheetName
           }
        });
    });
});

You could check the answer in a related question. https://stackoverflow.com/a/16894324/1465756

Just import library https://github.com/jasonpolites/gesture-imageview.

into your project and add the following in your layout file:

<LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:gesture-image="http://schemas.polites.com/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent">

<com.polites.android.GestureImageView
   android:id="@+id/image"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:src="@drawable/image"
   gesture-image:min-scale="0.1"
   gesture-image:max-scale="10.0"
   gesture-image:strict="false"/>`

Current route properties are present in this.$route, this.$router is the instance of router object which gives the configuration of the router. You can get the current route query using this.$route.query

If all you need is to show custom pages which have some fancy error messages for your site when DEBUG = False, then add two templates named 404.html and 500.html in your templates directory and it will automatically pick up this custom pages when a 404 or 500 is raised.

The almighty switch works well here:

'one
two
three' > file

$regex = '^t'

switch -regex -file file { 
  $regex { "line is $_" } 
}

Output:

line is two
line is three

Hj, all methods of yours are not working for me, in Fedora KDE 14. I have a dirty way to do bring a window to front, while we're waiting for Oracle to fix this issue.

import java.awt.MouseInfo;
import java.awt.Point;
import java.awt.Robot;
import java.awt.event.InputEvent;

public class FrameMain extends javax.swing.JFrame {

  //...
  private final javax.swing.JFrame mainFrame = this;

  private void toggleVisible() {
    setVisible(!isVisible());
    if (isVisible()) {
      toFront();
      requestFocus();
      setAlwaysOnTop(true);
      try {
        //remember the last location of mouse
        final Point oldMouseLocation = MouseInfo.getPointerInfo().getLocation();

        //simulate a mouse click on title bar of window
        Robot robot = new Robot();
        robot.mouseMove(mainFrame.getX() + 100, mainFrame.getY() + 5);
        robot.mousePress(InputEvent.BUTTON1_DOWN_MASK);
        robot.mouseRelease(InputEvent.BUTTON1_DOWN_MASK);

        //move mouse to old location
        robot.mouseMove((int) oldMouseLocation.getX(), (int) oldMouseLocation.getY());
      } catch (Exception ex) {
        //just ignore exception, or you can handle it as you want
      } finally {
        setAlwaysOnTop(false);
      }
    }
  }

  //...

}

And, this works perfectly in my Fedora KDE 14 :-)

const int nRows = 20;
const int nCols = 10;
int (*name)[nCols] = new int[nRows][nCols];
std::memset(name, 0, sizeof(int) * nRows * nCols); //row major contiguous memory
name[0][0] = 1; //first element
name[nRows-1][nCols-1] = 1; //last element
delete[] name;

There is a little hack with php. And it works not only with Google, but with any website you don't control and can't add Access-Control-Allow-Origin *

We need to create PHP-file (ex. getContentFromUrl.php) on our webserver and make a little trick.

PHP

<?php

$ext_url = $_POST['ext_url'];

echo file_get_contents($ext_url);

?>

JS

$.ajax({
    method: 'POST',
    url: 'getContentFromUrl.php', // link to your PHP file
    data: {
        // url where our server will send request which can't be done by AJAX
        'ext_url': 'https://stackoverflow.com/questions/6114436/access-control-allow-origin-error-sending-a-jquery-post-to-google-apis'
    },
    success: function(data) {
        // we can find any data on external url, cause we've got all page
        var $h1 = $(data).find('h1').html();

        $('h1').val($h1);
    },
    error:function() {
        console.log('Error');
    }
});

How it works:

1. Your browser with the help of JS will send request to your server
2. Your server will send request to any other server and get reply from another server (any website)
3. Your server will send this reply to your JS

And we can make events onClick, put this event on some button. Hope this will help!

Most easy way: sort files with sort(1) and then use diff(1).

What is meta_key? Strip out all of the meta_value conditionals, reduce, and you end up with this:

SELECT
*
FROM
meta_data
WHERE
(
        (meta_key = 'lat')
)
AND
(
        (meta_key = 'long')
)
GROUP BY
item_id

Since meta_key can never simultaneously equal two different values, no results will be returned.

Based on comments throughout this question and answers so far, it sounds like you're looking for something more along the lines of this:

SELECT
*
FROM
meta_data
WHERE
(
    (meta_key = 'lat')
    AND
    (
        (meta_value >= '60.23457047672217')
        OR
        (meta_value <= '60.23457047672217')
    )
)
OR

    (meta_key = 'long')
    AND
    (
        (meta_value >= '24.879140853881836')
        OR
        (meta_value <= '24.879140853881836')
    )
)
GROUP BY
item_id

Note the OR between the top-level conditionals. This is because you want records which are lat or long, since no single record will ever be lat and long.

I'm still not sure what you're trying to accomplish by the inner conditionals. Any non-null value will match those numbers. So maybe you can elaborate on what you're trying to do there. I'm also not sure about the purpose of the GROUP BY clause, but that might be outside the context of this question entirely.

An excerpt from an apple technical note (Thanks to matthias-bauch)

Xcode includes all your command-line tools. If it is installed on your system, remove it to uninstall your tools.

If your tools were downloaded separately from Xcode, then they are located at /Library/Developer/CommandLineTools on your system. Delete the CommandLineTools folder to uninstall them.

you could easily delete using terminal:

Here is an article that explains how to remove the command line tools but do it at your own risk.Try this only if any of the above doesn't work.

For scripts, I always use ksh because it smooths over gotchas.

But I find bash more comfortable for interactive use. For me the emacs key bindings and tab completion are the main benefits. But that's mostly force of habit, not any technical issue with ksh.

You should use input type="button" instead of input type="submit".

<form>
  <input type="button" value="Remove DUMMY" onclick="removeDummy(); "/>
 </form>

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

AB.reserve( A.size() + B.size() ); // preallocate memory
AB.insert( AB.end(), A.begin(), A.end() );
AB.insert( AB.end(), B.begin(), B.end() );

You can simply export the table with a query clause using datapump and import it back with table_exists_action=replace clause. Its will drop and recreate your table and take very less time. Please read about it before implementing.

You can combine this all into one formula, but you need to use a regular IF first to find out if the VLOOKUP came back with something, then use your COUNTIF if it did.

=IF(ISERROR(VLOOKUP(B1,Sheet2!A1:A9,1,FALSE)),"Not there",COUNTIF(Sheet2!A1:A9,B1))

In this case, Sheet2-A1:A9 is the range I was searching, and Sheet1-B1 had the value I was looking for ("To retire" in your case).

{'document_root', settings.STATIC_ROOT} needs to be {'document_root': settings.STATIC_ROOT}

or you'll get an error like dictionary update sequence element #0 has length 6; 2 is required

You can use standard JS toFixed method

var num = 5.56789;
var n=num.toFixed(2);

//5.57

In order to add commas (to separate 1000's) you can add regexp as follows (where num is a number):

num.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,")

//100000 => 100,000
//8000 => 8,000
//1000000 => 1,000,000

Complete example:

var value = 1250.223;
var num = '$' + value.toFixed(2).replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,");

//document.write(num) would write value as follows: $1,250.22

Separation character depends on country and locale. For some countries it may need to be .

First of all to see how many revisions you are behind locally, you should do a git fetch to make sure you have the latest info from your remote.

The default output of git status tells you how many revisions you are ahead or behind, but usually I find this too verbose:

$ git status
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 2 and 1 different commit each, respectively.
#
nothing to commit (working directory clean)

I prefer git status -sb:

$ git status -sb
## master...origin/master [ahead 2, behind 1]

In fact I alias this to simply git s, and this is the main command I use for checking status.

To see the diff in the "ahead revisions" of master, I can exclude the "behind revisions" from origin/master:

git diff master..origin/master^

To see the diff in the "behind revisions" of origin/master, I can exclude the "ahead revisions" from master:

git diff origin/master..master^^

If there are 5 revisions ahead or behind it might be easier to write like this:

git diff master..origin/master~5
git diff origin/master..master~5

UPDATE

To see the ahead/behind revisions, the branch must be configured to track another branch. For me this is the default behavior when I clone a remote repository, and after I push a branch with git push -u remotename branchname. My version is 1.8.4.3, but it's been working like this as long as I remember.

As of version 1.8, you can set the tracking branch like this:

git branch --track test-branch

As of version 1.7, the syntax was different:

git branch --set-upstream test-branch

this might help. It worked for me. try it in the terminal

setenforce 0

You can simply wrap your list as a data.frame (data.frame is in fact a special kind of list). Here is an example:

mylist = list() 
mylist[["a"]] = 1:10 
mylist[["b"]] = letters[1:10]
write.table(as.data.frame(mylist),file="mylist.csv", quote=F,sep=",",row.names=F)

or alternatively you can use write.csv (a wrapper around write.table). For the conversion of the list , you can use both as.data.frame(mylist) and data.frame(mylist).

To help in making a reproducible example, you can use functions like dput on your data.

if("123".search(/^\d+$/) >= 0){
   // its a number
}

Please note instead of

public TomcatEmbeddedServletContainerFactory tomcatFactory()

I had to use the following method signature

public EmbeddedServletContainerFactory embeddedServletContainerFactory() 

Use %systemdrive%%homepath%. %systemdrive% gives drive character ( Mostly C: ) and %homepath% gives user home directory ( \Users\<USERNAME> ).

Actually what you are searching is: Optional.map. Your code would then look like:

object.map(o -> "result" /* or your function */)
      .orElseThrow(MyCustomException::new);

I would rather omit passing the Optional if you can. In the end you gain nothing using an Optional here. A slightly other variant:

public String getString(Object yourObject) {
  if (Objects.isNull(yourObject)) { // or use requireNonNull instead if NullPointerException suffices
     throw new MyCustomException();
  }
  String result = ...
  // your string mapping function
  return result;
}

If you already have the Optional-object due to another call, I would still recommend you to use the map-method, instead of isPresent, etc. for the single reason, that I find it more readable (clearly a subjective decision ;-)).

Another option is to check for regular expression match on the command output.

For example:

[[ "$(./somecommand)" =~ "sub string" ]] && echo "Output includes 'sub string'"

I faced the same issue ... little work around (only for implementation not anonymous objects ) ... we can declare the class level exception object as null ... then initialize it inside the catch block for run method ... if there was error in run method,this variable wont be null .. we can then have null check for this particular variable and if its not null then there was exception inside the thread execution.

class TestClass implements Runnable{
    private Exception ex;

        @Override
        public void run() {
            try{
                //business code
               }catch(Exception e){
                   ex=e;
               }
          }

      public void checkForException() throws Exception {
            if (ex!= null) {
                throw ex;
            }
        }
}     

call checkForException() after join()

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.

Example:

<div class="editor-field">
    <%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
    <%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>

Here's a more specific example:

I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).

I made the following model:

namespace DeleteMeQuestion.Models
{
    public class QuizModel
    {
        public int ParentQuestionId { get; set; }
        public int QuestionId { get; set; }
        public string QuestionDisplayText { get; set; }
        public List<Response> Responses { get; set; }

        [Range(1,999, ErrorMessage = "Please choose a response.")]
        public int SelectedResponse { get; set; }
    }

    public class Response
    {
        public int ResponseId { get; set; }
        public int ChildQuestionId { get; set; }
        public string ResponseDisplayText { get; set; }
    }
}

There's a simple range validator in the model, just for fun. Next up, I made the following controller:

namespace DeleteMeQuestion.Controllers
{
    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index(int? id)
        {
            // TODO: get question to show based on method parameter 
            var model = GetModel(id);
            return View(model);
        }

        [HttpPost]
        public ActionResult Index(int? id, QuizModel model)
        {
            if (!ModelState.IsValid)
            {
                var freshModel = GetModel(id);
                return View(freshModel);
            }

            // TODO: save selected answer in database
            // TODO: get next question based on selected answer (hard coded to 999 for now)

            var nextQuestionId = 999;
            return RedirectToAction("Index", "Home", new {id = nextQuestionId});
        }

        private QuizModel GetModel(int? questionId)
        {
            // just a stub, in lieu of a database

            var model = new QuizModel
            {
                QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
                QuestionId = 1,
                Responses = new List<Response>
                                                {
                                                    new Response
                                                        {
                                                            ChildQuestionId = 2,
                                                            ResponseId = 1,
                                                            ResponseDisplayText = "Red"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 3,
                                                            ResponseId = 2,
                                                            ResponseDisplayText = "Blue"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 4,
                                                            ResponseId = 3,
                                                            ResponseDisplayText = "Green"
                                                        },
                                                }
            };

            return model;
        }
    }
}

Finally, I made the following view that makes use of the model:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>

<asp:Content ContentPlaceHolderID="TitleContent" runat="server">
    Home Page
</asp:Content>

<asp:Content ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm()) { %>

        <div>

            <h1><%: Model.QuestionDisplayText %></h1>

            <div>
            <ul>
            <% foreach (var item in Model.Responses) { %>
                <li>
                    <%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
                    <label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
                </li>
            <% } %>
            </ul>

            <%= Html.ValidationMessageFor(m => m.SelectedResponse) %>

        </div>

        <input type="submit" value="Submit" />

    <% } %>

</asp:Content>

As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.

This gives you the radio buttons with the same name attribute, but different ID attributes.

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

ytd2 is a fully functional YouTube video downloader. Check out its source code if you want to see how it's done.

Alternatively, you can also call an external process like youtube-dl to do the job. This is probably the easiest solution but it isn't in "pure" Java.

Use the following code:

<g transform="scale(0.1)">
...
</g>

You get the warning because you did not assign a value to one, which is a pointer. This is undefined behavior.

You should declare it like this:

Vector* one = malloc(sizeof(Vector));

or like this:

Vector one;

in which case you need to replace -> operator with . like this:

one.a = 12;
one.b = 13;
one.c = -11;

Finally, in C99 and later you can use designated initializers:

Vector one = {
   .a = 12
,  .b = 13
,  .c = -11
};

Also note that "in" keyword does not work on arrays. It works on objects only.

propName in myObject

Array inclusion test is

myArray.includes('three');

There's not a good way to convert it to foreach, because mysql_fetch_array() just fetches the next result from $result_select. If you really wanted to foreach, you could do pull all the results into an array first, doing something like the following:

$result_list = array();
while($row = mysql_fetch_array($result_select)) {
   result_list[] = $row;
}

foreach($result_list as $row) {
   ...
}

But there's no good reason I can see to do that - and you still have to use the while loop, which is unavoidable due to how mysql_fetch_array() works. Why is it so important to use a foreach()?

EDIT: If this is just for learning purposes: you can't convert this to a foreach. You have to have a pre-existing array to use a foreach() instead of a while(), and mysql_fetch_array() fetches one result per call - there's no pre-existing array for foreach() to iterate through.

This may help you, I was getting this error because I was trying to reload my .profile with the command . .profile and it had a syntax error

Here's how I did it.

• Make/Convert csv file to be seperated by tabs (\t) AND not enclosed by any quotes (sqlite interprets quotes literally - says old docs)

• Enter the sqlite shell of the db to which the data needs to be added

  sqlite> .separator "\t" ---IMPORTANT! should be in double quotes sqlite> .import afile.csv tablename-to-import-to

That is the simple way of converting string into util date and sql date

String startDate="12-31-2014";
SimpleDateFormat sdf1 = new SimpleDateFormat("MM-dd-yyyy");
java.util.Date date = sdf1.parse(startDate);
java.sql.Date sqlStartDate = new java.sql.Date(date.getTime()); 

I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important property.

HTML

<a href="#" class="selected_btn" data-role="button">Button name</a>

CSS

.selected_btn
{
    border:1px solid red;
    text-decoration:none;
    font-family:helvetica;
    color:red !important;            
    background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}

Here is the demo

the user pressing enter or spaces is the same.

int count = 5;
int list[count]; // array of known length
cout << "enter the sequence of " << count << " numbers space separated: ";
// user inputs values space separated in one line.  Inputs more than the count are discarded.
for (int i=0; i<count; i++) {
    cin >> list[i];
}

You can pass in any CMake variable on the command line, or edit cached variables using ccmake/cmake-gui. On the command line,

cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr . && make all install

Would configure the project, build all targets and install to the /usr prefix. The type (PATH) is not strictly necessary, but would cause the Qt based cmake-gui to present the directory chooser dialog.

Some minor additions as comments make it clear that providing a simple equivalence is not enough for some. Best practice would be to use an external build directory, i.e. not the source directly. Also to use more generic CMake syntax abstracting the generator.

mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .. && cmake --build . --target install --config Release

You can see it gets quite a bit longer, and isn't directly equivalent anymore, but is closer to best practices in a fairly concise form... The --config is only used by multi-configuration generators (i.e. MSVC), ignored by others.

Today NodeJS supports new async/await syntax. This is an easy syntax and makes the life much easier

async function process(promises) { // must be an async function
    let x = await Promise.all(promises);  // now x will be an array
    x = x.map( tmp => tmp * 10);              // proccessing the data.
}

const promises = [
   new Promise(resolve => setTimeout(resolve, 0, 1)),
   new Promise(resolve => setTimeout(resolve, 0, 2))
];

process(promises)

end if;

It seems that you catch not the exception you wanna catch out there :)

if the s is a socket.socket() object, then the right way to call .connect would be:

import socket
s = socket.socket()
address = '127.0.0.1'
port = 80  # port number is a number, not string
try:
    s.connect((address, port)) 
    # originally, it was 
    # except Exception, e: 
    # but this syntax is not supported anymore. 
except Exception as e: 
    print("something's wrong with %s:%d. Exception is %s" % (address, port, e))
finally:
    s.close()

Always try to see what kind of exception is what you're catching in a try-except loop.

You can check what types of exceptions in a socket module represent what kind of errors (timeout, unable to resolve address, etc) and make separate except statement for each one of them - this way you'll be able to react differently for different kind of problems.

no, the difference between + and \; should be reversed. + appends the files to the end of the exec command then runs the exec command and \; runs the command for each file.

The problem is find . -type f -iname '*.cpp' -exec mv {} ./test/ \+ should be find . -type f -iname '*.cpp' -exec mv {} ./test/ + no need to escape it or terminate the +

xargs I haven't used in a long time but I think works like +.

This error is often caused by incompatible jQuery versions. I encountered the same error with a foundation 6 repository. My repository was using jQuery 3, but foundation requires an earlier version. I then changed it and it worked.

If you look at the version of jQuery required by the foundation 5 dependencies it states "jquery": "~2.1.0".

Can you confirm that you are loading the correct version of jQuery?

I hope this helps.

You can use jQuery Mobile vclick event:

Lately, BitBucket needs you to generate an App Password:

Settings/Access Management/App Passwords.

https://bitbucket.org/account/user/.../app-passwords

This can have different reasons like:

• You are using an incorrect password
• The MySQL server got an error when trying to resolve the IP address of the client host to a name
• No privileges are granted to the user

You can try one of the following steps:

To reset the password for the remote user by:

SET PASSWORD FOR some_user@ip_addr_of_remote_client=PASSWORD('some_password');

To grant access to the user by:

GRANT SELECT, INSERT, UPDATE, DELETE, LOCK TABLES ON YourDB.* TO user@Host IDENTIFIED by 'password';

Hope this helps you, if not then you will have to go through the documentation

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

One subtle but significant difference is in the way the two libraries approach scope. Mustache will fall back to parent scope if it can't find a variable within the current context; Handlebars will return a blank string.

This is barely mentioned in the GitHub README, where there's one line for it:

Handlebars deviates from Mustache slightly in that it does not perform recursive lookup by default.

However, as noted there, there is a flag to make Handlebars behave in the same way as Mustache -- but it affects performance.

This has an effect on the way you can use # variables as conditionals.

For example in Mustache you can do this:

{{#variable}}<span class="text">{{variable}}</span>{{/variable}}

It basically means "if variable exists and is truthy, print a span with the variable in it". But in Handlebars, you would either have to:

• use {{this}} instead
• use a parent path, i.e., {{../variable}} to get back out to relevant scope
• define a child variable value within the parent variable object

More details on this, if you want them, here.

One thing that I'm surprised hasn't been mentioned yet is that implementing Runnable makes your class more flexible.

If you extend thread then the action you're doing is always going to be in a thread. However, if you implement Runnable it doesn't have to be. You can run it in a thread, or pass it to some kind of executor service, or just pass it around as a task within a single threaded application (maybe to be run at a later time, but within the same thread). The options are a lot more open if you just use Runnable than if you bind yourself to Thread.

It is possible in 12.1.

Find idea.properties in the BIN folder inside of wherever your IDE is installed, e.g. C:\Program Files (x86)\JetBrains\IntelliJ\bin

Add a new line to the end of that file:

auto.show.quick.doc=true

Start IDEA and just hover your mouse over something:

There are two possible approaches; either you create a unique value and store somewhere along with the creation time, for example in a database, or you put the creation time inside the token so that you can decode it later and see when it was created.

To create a unique token:

string token = Convert.ToBase64String(Guid.NewGuid().ToByteArray());

Basic example of creating a unique token containing a time stamp:

byte[] time = BitConverter.GetBytes(DateTime.UtcNow.ToBinary());
byte[] key = Guid.NewGuid().ToByteArray();
string token = Convert.ToBase64String(time.Concat(key).ToArray());

To decode the token to get the creation time:

byte[] data = Convert.FromBase64String(token);
DateTime when = DateTime.FromBinary(BitConverter.ToInt64(data, 0));
if (when < DateTime.UtcNow.AddHours(-24)) {
  // too old
}

Note: If you need the token with the time stamp to be secure, you need to encrypt it. Otherwise a user could figure out what it contains and create a false token.
