I haven't yet worked with many languages and deal mostly with scripting languages; out of these VBScript is the one I like least. Although it has some handy features, some things really piss me off:

• Object assignments are made using the Set keyword:

  Set foo = Nothing
  

  Omitting Set is one of the most common causes of run-time errors.

• No such thing as structured exception handling. Error checking is like this:

  On Error Resume Next
  
  ' Do something
  
  If Err.Number <> 0
    ' Handle error
    Err.Clear
  End If
  
  ' And so on
  

• Enclosing the procedure call parameters in parentheses requires using the Call keyword:

  Call Foo (a, b)
  

• Its English-like syntax is way too verbose. (I'm a fan of curly braces.)

• Logical operators are long-circuit. If you need to test a compound condition where the subsequent condition relies on the success of the previous one, you need to put conditions into separate If statements.

• Lack of parameterized class constructors.

• To wrap a statement into several lines, you have to use an underscore:

  str = "Hello, " & _
        "world!"
  

• Lack of multiline comments.

Edit: found this article: The Flangy Guide to Hating VBScript. The author sums up his complaints as "VBS isn't Python" :)

apt-get install python-setuptools python-pip

or

apt-get install python3-setuptools python3-pip

you'd also want to install the python packages...

This is happen when you try to push initially.Because in your GitHub repo have readMe.md or any other new thing which is not in your local repo. First you have to merge unrelated history of your github repo.To do that

git pull origin master --allow-unrelated-histories

then you can get the other files from repo(readMe.md or any)using this

git pull origin master

After that

git push -u origin master

Now you successfully push your all the changes into Github repo.I'm not expert in git but every time these step work for me.

This seems a lot cleaner than the answer above...

<script>
var maxID = 0;
function getTemplateRow() {
var x = document.getElementById("templateRow").cloneNode(true);
x.id = "";
x.style.display = "";
x.innerHTML = x.innerHTML.replace(/{id}/, ++maxID);
return x;
}
function addRow() {
var t = document.getElementById("theTable");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
r.parentNode.insertBefore(getTemplateRow(), r);

}
</script>


<table id="theTable">

My problem was that excel column was showing me "=concatenate(A1,B1)" instead of it 's value after concatenation.

I added a space after "," like this =concatenate(A1, B1) and it worked.

This is just an example that solved my problem.

Try and let me know if it works for you as well.

Sometimes it works without space as well, but at other times it doesn't.

For browser close you can put below code into your web.config :

<system.web>
    <sessionState mode="InProc"></sessionState>
 </system.web>

It will destroy your session when browser is closed, but it will not work for tab close.

- (void)performAndWait:(void (^)(dispatch_semaphore_t semaphore))perform;
{
  NSParameterAssert(perform);
  dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
  perform(semaphore);
  dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
  dispatch_release(semaphore);
}

Example usage:

[self performAndWait:^(dispatch_semaphore_t semaphore) {
  [self someLongOperationWithSuccess:^{
    dispatch_semaphore_signal(semaphore);
  }];
}];

I have obj and bin files that accidentally made it into the repo that I don't want polluting my 'changed files' list

After I noticed they went to the remote, I ignored them by adding this to .gitignore

/*/obj
/*/bin

Problem is they are already in the remote, and when they get changed, they pop up as changed and pollute the changed file list.

To stop seeing them, you need to delete the whole folder from the remote repository.

In a command prompt:

1. CD to the repo folder (i.e. C:\repos\MyRepo)
2. I want to delete SSIS\obj. It seems you can only delete at the top level, so you now need to CD into SSIS: (i.e. C:\repos\MyRepo\SSIS)
3. Now type the magic incantation git rm -r -f obj
   • rm=remove
   • -r = recursively remove
   • -f = means force, cause you really mean it
   • obj is the folder
4. Now run git commit -m "remove obj folder"

I got an alarming message saying 13 files changed 315222 deletions

Then because I didn't want to have to look up the CMD line, I went into Visual Sstudio and did a Sync to apply it to the remote

Or this:

print '{0:02d}'.format(1)

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

You want to make the format/style explicit and don't rely on interpretation based on local settings (which may vary among your clients infrastructure).

DECLARE @Test AS DATETIME
SET @Test = CONVERT(DATETIME, '2011-02-15 00:00:00', 120) -- yyyy-MM-dd hh:mm:ss
SELECT @Test

While there is a plethora of styles, you may want to remember few

• 126 (ISO 8601): yyyy-MM-ddThh:mm:ss(.mmm)
• 120: yyyy-MM-dd hh:mm:ss
• 112: yyyyMMdd

Note that the T in the ISO 8601 is actually the letter T and not a variable.

Is the $_SESSION['name'] variable an array? If you want to delete a specific key from within an array, you have to refer to that exact key in the unset() call, otherwise you delete the entire array, e.g.

$name = array(0 => 'a', 1 => 'b', 2 => 'c');
unset($name); // deletes the entire array
unset($name[1]); // deletes only the 'b' entry

Another minor problem with your snippet: You're mixing GET query parameters in with a POST form. Is there any reason why you can't do the forms with 'name' being passed in a hidden field? It's best to not mix get and post variables, especially if you use $_REQUEST elsewhere. You can run into all kinds of fun trying to figure out why $_GET['name'] isn't showing up the same as $_POST['name'], because the server's got a differnt EGPCS order set in the 'variables_order' .ini setting.

<form blah blah blah method="post">
  <input type="hidden" name="name" value="<?= htmlspecialchars($list1) ?>" />
  <input type="submit" name="add" value="Add />
</form>

And note the htmlspecialchars() call. If either $list1 or $list2 contain a double quote ("), it'll break your HTML

I found this code working:

from distutils.dir_util import copy_tree

# copy subdirectory example
fromDirectory = "/a/b/c"
toDirectory = "/x/y/z"

copy_tree(fromDirectory, toDirectory)

Reference:

• Python 2: https://docs.python.org/2/distutils/apiref.html#distutils.dir_util.copy_tree
• Python 3: https://docs.python.org/3/distutils/apiref.html#distutils.dir_util.copy_tree

If you want to run a few scripts, you can use Set-executionpolicy -ExecutionPolicy Unrestricted and then reset with Set-executionpolicy -ExecutionPolicy Default.

Note that execution policy is only checked when you start its execution (or so it seems) and so you can run jobs in the background and reset the execution policy immediately.

# Check current setting
Get-ExecutionPolicy

# Disable policy
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
# Choose [Y]es

Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 example.com | tee ping__example.com.txt }
Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 google.com  | tee ping__google.com.txt  }

# Can be run immediately
Set-ExecutionPolicy -ExecutionPolicy Default
# [Y]es

Could someone explain the logic behind turning rest of the fields to false in below code (from above post)

One thing I noticed is that neither of the top two methods have any notion of what color the first row should be in a group; the group will just start with the opposite color from the last line of the previous group. I wanted my groups to always start with the same color...the first row of each group should always be white, and the next row colored.

The basic concept was to reset the toggle when each group starts, so I added a bit of code:

Private bOddRow As Boolean
'*************************************************************************
'-- Display green-bar type color banding in detail rows
'-- Call from BackGroundColor property of all detail row textboxes
'-- Set Toggle True for first item, False for others.
'*************************************************************************
'
Function AlternateColor(ByVal OddColor As String, _
                  ByVal EvenColor As String, ByVal Toggle As Boolean) As String
         If Toggle Then bOddRow = Not bOddRow
         If bOddRow Then 
                Return OddColor
         Else
                 Return EvenColor
         End If
 End Function
 '
 Function RestartColor(ByVal OddColor As String) As String
         bOddRow = True
         Return OddColor
 End Function

So I have three different kinds of cell backgrounds now:

1. First column of data row has =Code.AlternateColor("AliceBlue", "White", True) (This is the same as the previous answer.)
2. Remaining columns of data row have =Code.AlternateColor("AliceBlue", "White", False) (This, also, is the same as the previous answer.)
3. First column of grouping row has =Code.RestartColor("AliceBlue") (This is new.)
4. Remaining columns of grouping row have =Code.AlternateColor("AliceBlue", "White", False) (This was used before, but no mention of it for grouping row.)

This works for me. If you want the grouping row to be non-colored, or a different color, it should be fairly obvious from this how to change it around.

Please feel free to add comments about what could be done to improve this code: I'm brand new to both SSRS and VB, so I strongly suspect that there's plenty of room for improvement, but the basic idea seems sound (and it was useful for me) so I wanted to throw it out here.

The problem is in the import line. You are importing a module, not a class. Assuming your file is named other_file.py (unlike java, again, there is no such rule as "one class, one file"):

from other_file import findTheRange

if your file is named findTheRange too, following java's convenions, then you should write

from findTheRange import findTheRange

you can also import it just like you did with random:

import findTheRange
operator = findTheRange.findTheRange()

Some other comments:

a) @Daniel Roseman is right. You do not need classes here at all. Python encourages procedural programming (when it fits, of course)

b) You can build the list directly:

  randomList = [random.randint(0, 100) for i in range(5)]

c) You can call methods in the same way you do in java:

largestInList = operator.findLargest(randomList)
smallestInList = operator.findSmallest(randomList)

d) You can use built in function, and the huge python library:

largestInList = max(randomList)
smallestInList = min(randomList)

e) If you still want to use a class, and you don't need self, you can use @staticmethod:

class findTheRange():
    @staticmethod
    def findLargest(_list):
        #stuff...

This is because of ng-include which creates a new child scope, so $scope.lineText isn’t changed. I think that this refers to the current scope, so this.lineText should be set.

RedirectToAction("actionName", "controllerName");

It has other overloads as well, please check up!

Also, If you are new and you are not using T4MVC, then I would recommend you to use it!

It gives you intellisence for actions,Controllers,views etc (no more magic strings)

=IF(COUNTIF(A1:D1,FALSE)>0,FALSE,TRUE)

(or you can specify any other range to look in)

On Linux, you can use ldconfig, which maintains the ld.so configuration and cache, to print out the directories search by ld.so with

ldconfig -v 2>/dev/null | grep -v ^$'\t'

ldconfig -v prints out the directories search by the linker (without a leading tab) and the shared libraries found in those directories (with a leading tab); the grep gets the directories. On my machine, this line prints out

/usr/lib64/atlas:
/usr/lib/llvm:
/usr/lib64/llvm:
/usr/lib64/mysql:
/usr/lib64/nvidia:
/usr/lib64/tracker-0.12:
/usr/lib/wine:
/usr/lib64/wine:
/usr/lib64/xulrunner-2:
/lib:
/lib64:
/usr/lib:
/usr/lib64:
/usr/lib64/nvidia/tls: (hwcap: 0x8000000000000000)
/lib/i686: (hwcap: 0x0008000000000000)
/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib/sse2: (hwcap: 0x0000000004000000)
/usr/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib64/sse2: (hwcap: 0x0000000004000000)

The first paths, without hwcap in the line, are either built-in or read from /etc/ld.so.conf. The linker can then search additional directories under the basic library search path, with names like sse2 corresponding to additional CPU capabilities. These paths, with hwcap in the line, can contain additional libraries tailored for these CPU capabilities.

One final note: using -p instead of -v above searches the ld.so cache instead.

string Time = "16:23:01";
DateTime date = DateTime.Parse(Time, System.Globalization.CultureInfo.CurrentCulture);

string t = date.ToString("HH:mm:ss tt");

Ahahaha, here's a funny way I just came up with to do this:

select SYSDATE - ROWNUM
from shipment_weights sw
where ROWNUM < 365;

where shipment_weights is any large table;

Might it be possible that you're using a WCF-based web service reference? By default, the ServiceThrottlingBehavior.MaxConcurrentCalls is 16.

You could try updating your service reference behavior's <serviceThrottling> element

<serviceThrottling
    maxConcurrentCalls="999" 
    maxConcurrentSessions="999" 
    maxConcurrentInstances="999" />

(Note that I'd recommend the settings above.) See MSDN for more information how to configure an appropriate <behavior> element.

To activate debug mode in flask you simply type set FLASK_DEBUG=1 on your CMD for windows and export FLASK_DEBUG=1 on Linux termial then restart your app and you are good to go!!

For a Windows Store App, you won't have HttpUtility. Instead, you have:

For an URI, before the '?':

• System.Uri.EscapeUriString("example.com/Stack Overflow++?")
  • -> "example.com/Stack%20Overflow++?"

For an URI query name or value, after the '?':

• System.Uri.EscapeDataString("Stack Overflow++")
  • -> "Stack%20Overflow%2B%2B"

For a x-www-form-urlencoded query name or value, in a POST content:

• System.Net.WebUtility.UrlEncode("Stack Overflow++")
  • -> "Stack+Overflow%2B%2B"

You can also fetch data with hooks in your function components

full example with api call: https://codesandbox.io/s/jvvkoo8pq3

second example: https://jsfiddle.net/bradcypert/jhrt40yv/6/

const Repos = ({user}) => {
  const [repos, setRepos] = React.useState([]);

  React.useEffect(() => {
    const fetchData = async () => {
        const response = await axios.get(`https://api.github.com/users/${user}/repos`);
        setRepos(response.data);
    }

    fetchData();
  }, []);

  return (
  <div>
    {repos.map(repo =>
      <div key={repo.id}>{repo.name}</div>
    )}
  </div>
  );
}

ReactDOM.render(<Repos user="bradcypert" />, document.querySelector("#app"))

Try something like:

Add to html:

  <link id="shortcutIcon" rel="shortcut icon" type="image/x-icon">
  <link id="icon" rel="icon" type="image/x-icon">

Add minified script after tag:

<script type="text/javascript">
(function(b,c,d,a){a=c+d+b,document.getElementById('shortcutIcon').href=a,document.getElementById('icon').href=a;}(Math.random()*100,(document.querySelector('base')||{}).href,'/assets/images/favicon.ico?v='));
</script>

where

• '/assets/images/favicon.ico' related path to .ico
• ?v='Math.random()*100' - to force browser update favicon.ico

Before test clear history: (ctr + shfit + del)

Try adding JSON.stringify(result) to convert the JS Object into a JSON string.

From your code I can see you are logging the result in error which is called if the AJAX request fails, so I'm not sure how you'd go about accessing the id/name/etc. then (you are checking for success inside the error condition!).

Note that if you use Chrome's console you should be able to browse through the object without having to stringify the JSON, which makes it easier to debug.

string foo = "D:\\Projects\\Some\\Kind\\Of\\Pathproblem\\wuhoo.xml";

This will work, or the previous examples will, too. @"..." means treat everything between the quote marks literally, so you can do

@"Hello
world"

To include a literal newline. I'm more old school and prefer to escape "\" with "\\"

Sure You can. I'd say that You should.

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

By using pg_restore command you can restore postgres database

First open terminal type

sudo su postgres

Create new database

createdb [database name] -O [owner]

createdb test_db [-O openerp]

pg_restore -d [Database Name] [path of dump file]

pg_restore -d test_db /home/sagar/Download/sample_dbump

Wait for completion of database restoring.

Remember that dump file should have read, write, execute access, so for that you can apply chmod command

>>> nums = [1, 2, 3, 4, 5]    
>>> min(map((lambda t: ((float(t[0])/t[1]), t)), ((x, y) for x in nums for y in nums)))[1]
(1, 5)

In SQL Server Enterprise Manager, open \Server Objects\Linked Servers\Providers, right click on the OraOLEDB.Oracle provider, select properties and check the "Allow inprocess" option. Recreate your linked server and test again.

You can also execute the following query if you don't have access to SQL Server Management Studio :

EXEC master.dbo.sp_MSset_oledb_prop N'OraOLEDB.Oracle', N'AllowInProcess', 1

If the children have FKs linking them to the parent, then you can use DELETE CASCADE on the parent.

e.g.

CREATE TABLE supplier 
( supplier_id numeric(10) not null, 
 supplier_name varchar2(50) not null, 
 contact_name varchar2(50),  
 CONSTRAINT supplier_pk PRIMARY KEY (supplier_id) 
); 



CREATE TABLE products 
( product_id numeric(10) not null, 
 supplier_id numeric(10) not null, 
 CONSTRAINT fk_supplier 
   FOREIGN KEY (supplier_id) 
  REFERENCES supplier(supplier_id) 
  ON DELETE CASCADE 
); 

Delete the supplier, and it will delate all products for that supplier

Here is another variation on the Bootstrap 4.1 Navbar with multi-level dropdown. This one uses minimal CSS for the submenu, and can be re-positioned as desired:

https://www.codeply.com/go/nG6iMAmI2X

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-top: -1px;
}

jQuery to control display of submenus:

$('.dropdown-submenu > a').on("click", function(e) {
    var submenu = $(this);
    $('.dropdown-submenu .dropdown-menu').removeClass('show');
    submenu.next('.dropdown-menu').addClass('show');
    e.stopPropagation();
});

$('.dropdown').on("hidden.bs.dropdown", function() {
    // hide any open menus when parent closes
    $('.dropdown-menu.show').removeClass('show');
});

See this answer for activating the Bootstrap 4 submenus on hover

If you have updated your GitHub password on the GitHub server, in the first attempt of the git fetch/pull/push command it generates the authentication failed message.

Execute the same git fetch/pull/push command a second time and it prompts for credentials (username and password). Enter the username and the new updated password of the GitHub server and login will be successful.

Even I had this problem, and I performed the above steps and done!!

A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

You may also want to create the directory if it's not there.

Source, if it's still there on SO.

=====================================================================

On Python = 3.5, use pathlib.Path.mkdir:

from pathlib import Path
Path("/my/directory").mkdir(parents=True, exist_ok=True)

For older versions of Python, I see two answers with good qualities, each with a small flaw, so I will give my take on it:

Try os.path.exists, and consider os.makedirs for the creation.

import os
if not os.path.exists(directory):
    os.makedirs(directory)

As noted in comments and elsewhere, there's a race condition – if the directory is created between the os.path.exists and the os.makedirs calls, the os.makedirs will fail with an OSError. Unfortunately, blanket-catching OSError and continuing is not foolproof, as it will ignore a failure to create the directory due to other factors, such as insufficient permissions, full disk, etc.

One option would be to trap the OSError and examine the embedded error code (see Is there a cross-platform way of getting information from Python’s OSError):

import os, errno

try:
    os.makedirs(directory)
except OSError as e:
    if e.errno != errno.EEXIST:
        raise

Alternatively, there could be a second os.path.exists, but suppose another created the directory after the first check, then removed it before the second one – we could still be fooled.

Depending on the application, the danger of concurrent operations may be more or less than the danger posed by other factors such as file permissions. The developer would have to know more about the particular application being developed and its expected environment before choosing an implementation.

Modern versions of Python improve this code quite a bit, both by exposing FileExistsError (in 3.3+)...

try:
    os.makedirs("path/to/directory")
except FileExistsError:
    # directory already exists
    pass

...and by allowing a keyword argument to os.makedirs called exist_ok (in 3.2+).

os.makedirs("path/to/directory", exist_ok=True)  # succeeds even if directory exists.

In my machine which is ubuntu 14.04 with python 2.7 installed, if I go here,

/usr/local/lib/python2.7/dist-packages/nltk/

        cmd.append("-cp ").append(ManagementFactory.getRuntimeMXBean().getClassPath()).append(" ");
        cmd.append(Main.class.getName()).append(" ");
        for (String arg : args) {
            cmd.append(arg).append(" ");
        }
        Runtime.getRuntime().exec(cmd.toString());
        System.exit(0);
    }
}

Dedicated to all those who say it is impossible.

This program collects all information available to reconstruct the original commandline. Then, it launches it and since it is the very same command, your application starts a second time. Then we exit the original program, the child program remains running (even under Linux) and does the very same thing.

WARNING: If you run this, be aware that it never ends creating new processes, similar to a fork bomb.

this is might be a possible solution

void 0 != document.getElementById("ad") &&       (document.getElementById("ad").onclick =function(){
 var a = $("#client_id").val();
 var b = $("#contact").val();
 var c = $("#message").val();
 var Qdata = { client_id: a, contact:b, message:c }
 var respo='';
     $("#message").html('');

return $.ajax({

    url: applicationPath ,
    type: "POST",
    data: Qdata,
    success: function(e) {
         $("#mcg").html("msg send successfully");

    }

})

});

For whatever reason the above would not work for me. This is what did:

if (tabControl.SelectedTab.Name == "tabName" )
{
     .. do stuff
}

where tabControl.SelectedTab.Name is the name attribute assigned to the page in the tabcontrol itself.

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

You can show float numbers

• with a certain number of decimals
• with a certain format (localised)

i.e.

$myNonFormatedFloat = 5678.9

$myGermanNumber = number_format($myNonFormatedFloat, 2, ',', '.'); // -> 5.678,90

$myAngloSaxonianNumber = number_format($myNonFormatedFloat, 2, '.', ','); // -> 5,678.90 

Note that, the

1st argument is the float number you would like to format

2nd argument is the number of decimals

3rd argument is the character used to visually separate the decimals

4th argument is the character used to visually separate thousands

This will work only if you have access to the instance you want to change/add the key in. You can create a new key pair. Or if you already have the key pair, then you can paste the public key of the new pair in the authorized_keys file on your instance.

vim .ssh/authorized_keys

Now you can use the private key for that pair and log in.

Hope this helps.

What the other thing you can do is go to: /etc/sudoers

There add the following line which gives the permission to that user www-data ALL=(ALL:ALL) ALL Why www-data ? this is because apache is running by this user name.

Incase if your user is different then try username ALL=(ALL:ALL) ALL

This worked for me.

Yep, why not?

fs.Write(myByteArray, 0, myByteArray.Length);

That's pretty much all you need:

mysql> select * from t;
+------+-------+
| id   | data  |
+------+-------+
|    1 | max   |
|    2 | linda |
|    3 | sam   |
|    4 | henry |
+------+-------+
4 rows in set (0.02 sec)

mysql> update t set data=concat(data, 'a');
Query OK, 4 rows affected (0.01 sec)
Rows matched: 4  Changed: 4  Warnings: 0

mysql> select * from t;
+------+--------+
| id   | data   |
+------+--------+
|    1 | maxa   |
|    2 | lindaa |
|    3 | sama   |
|    4 | henrya |
+------+--------+
4 rows in set (0.00 sec)

Not sure why you'd be having trouble, though I am testing this on 5.1.41

asyncio.wait is more low level than asyncio.gather.

As the name suggests, asyncio.gather mainly focuses on gathering the results. It waits on a bunch of futures and returns their results in a given order.

asyncio.wait just waits on the futures. And instead of giving you the results directly, it gives done and pending tasks. You have to manually collect the values.

Moreover, you could specify to wait for all futures to finish or just the first one with wait.

no_of_lines = 5
lines = ""
for i in xrange(5):
    lines+=input()+"\n"
    a=raw_input("if u want to continue (Y/n)")
    ""
    if(a=='y'):
        continue
    else:
        break
    print lines

In case you don't want to set fixed width to anything

The solution below allows you to have table cell content that is long, but must not affect the width of the parent table, nor the height of the parent row. For example where you want to have a table with width:100% that still applies auto-size feature to all other cells. Useful in data grids with "Notes" or "Comment" column or something.

Add these 3 rules to your CSS:

.text-overflow-dynamic-container {
    position: relative;
    max-width: 100%;
    padding: 0 !important;
    display: -webkit-flex;
    display: -moz-flex;
    display: flex;
    vertical-align: text-bottom !important;
}
.text-overflow-dynamic-ellipsis {
    position: absolute;
    white-space: nowrap;
    overflow-y: visible;
    overflow-x: hidden;
    text-overflow: ellipsis;
    -ms-text-overflow: ellipsis;
    -o-text-overflow: ellipsis;
    max-width: 100%;
    min-width: 0;
    width:100%;
    top: 0;
    left: 0;
}
.text-overflow-dynamic-container:after,
.text-overflow-dynamic-ellipsis:after {
    content: '-';
    display: inline;
    visibility: hidden;
    width: 0;
}

Format HTML like this in any table cell you want dynamic text overflow:

<td>
  <span class="text-overflow-dynamic-container">
    <span class="text-overflow-dynamic-ellipsis" title="...your text again for usability...">
      //...your long text here...
    </span>
  </span>
</td>

Additionally apply desired min-width (or none at all) to the table cell.

Of course the fiddle: https://jsfiddle.net/9wycg99v/23/

If you put it in a PictureBox control, it should just work

For question 1:

SELECT DISTINCT a.*
  FROM [Table] a
  INNER JOIN
  [Table] b
  ON
  a.C1 <> b.C1 AND a.C2 = b.C2 AND a.C3 = b.C3 AND a.C4 = b.C4

Using an inner join is much more efficient than a subquery because it requires fewer operations, and maintains the use of indexes when comparing the values, allowing the SQL server to better optimize the query before its run. Using appropriate indexes with this query can bring your query down to only n * log(n) rows to compare.

Using a subquery with your where clause or only doing a standard join where C1 does not equal C2 results in a table that has roughly 2 to the power of n rows to compare, where n is the number of rows in the table.

So by using proper indexing with an Inner Join, which only returns records which met the join criteria, we're able to drastically improve the performance. Also note that we return DISTINCT a.*, because this will only return the columns for table a where the join criteria was met. Returning * would return the columns for both a and b where the criteria was met, and not including DISTINCT would result in a duplicate of each row for each time that row row matched another row more than once.

A similar approach could also be performed using CROSS APPLY, which still uses a subquery, but makes use of indexes more efficiently.

An implementation with the keyword USING instead of ON could also work, but the syntax is more complicated to make work because your want to match on rows where C1 does not match, so you would need an additional where clause to filter out matching each row with itself. Also, USING is not compatible/allowed in conjunction with table values in all implementations of SQL, so it's best to stick with ON.

Similarly, for question 2:

SELECT DISTINCT a.*
  FROM [Table] a
  INNER JOIN
  [Table] b
  ON
  a.C1 <> b.C1 AND a.C4 = b.C4

This is essentially the same query as for 1, but because it only wants to know which rows match for C4, we only compare on the rows for C4.

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

If your system is in English, use @Rick answer:

If your system is in Brazilian Portuguese, use this:

Import:

<script
        src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

    <script     src="https://cdnjs.cloudflare.com/ajax/libs/jquery.mask/1.14.15/jquery.mask.min.js"></script>

    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.inputmask/3.2.6/jquery.inputmask.bundle.min.js"></script>

HTML:

<input class="mask" type="text" />

JS:

$(".mask").inputmask('Regex', {regex: "^[0-9]{1,6}(\\,\\d{1,2})?$"});

Its because in Brazilian Portuguese we write "1.000.000,00" and not "1,000,000.00" like in English, so if you use "." the system will not understand a decimal mark.

It is it, I hope that it help someone. I spend a lot of time to understand it.

For users on slow connections, external scripts dynamically injected via document.write() can delay page load by tens of seconds.

I've found yet an easier way to write to a Zebra printer over a COM port. I went to the Windows control panel and added a new printer. For the port, I chose COM1 (the port the printer was plugged in to). I used a "Generic / Text Only" printer driver. I disabled the print spooler (a standard option in the printer preferences) as well as all advanced printing options. Now, I can just print any string to that printer and if the string contains ZPL, the printer renders the ZPL just fine! No need for special "start sequences" or funky stuff like that. Yay for simplicity!

If you have a fixed width element and know the width of your background image, you can simply set the background-position to : the element's width - the image's width - the gap you want on the right.

For example : with a 100px-wide element and a 300px-wide image, to get a gap of 10px on the right, you set it to 100-300-10=-210px :

#myElement {
  background:url(my_image.jpg) no-repeat -210px top;
  width:100px;
}

And you get the rightmost 80 pixels of your image on the left of your element, and a gap of 20px on the right.

I know it can sound stupid but sometimes it saves the time... I use that much in a vertical manner (gap at bottom) for navigation links with text below image.

Not sure it applies to your case though.

if you want that not contains any of a-z and A-Z:

SELECT * FROM mytable WHERE NOT REGEXP_LIKE(column_1, '[A-Za-z]')

something like:

"98763045098" or "!%436%$7%$*#"

or other languages like persian, arabic and ... like this:

"???? ????"

Seems like the general query log is the file that you need. A good introduction to this is at http://dev.mysql.com/doc/refman/5.1/en/query-log.html

All of the functionality of our lightweight IDEs can be found within IntelliJ IDEA (you need to install the corresponding plug-ins from the repository).

It includes support for all technologies developed for our more specific products such as Web/PhpStorm, RubyMine and PyCharm.

The specific feature missing from IntelliJ IDEA is simplified project creation ("Open Directory") used in lighter products as it is not applicable to the IDE that support such a wide range of languages and technologies. It also means that you can't create projects directly from the remote hosts in IDEA.

If you are missing any other feature that is available in lighter products, but is not available in IntelliJ IDEA Ultimate, you are welcome to report it and we'll consider adding it.

While PHP, Python and Ruby IDEA plug-ins are built from the same source code as used in PhpStorm, PyCharm and RubyMine, product release cycles are not synchronized. It means that some features may be already available in the lighter products, but not available in IDEA plug-ins at certain periods, they are added with the plug-in and IDEA updates later.

Use brackets to group the OR statements.

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND (date='$Date_Today' OR date='$Date_Yesterday' OR date='$Date_TwoDaysAgo' OR date='$Date_ThreeDaysAgo' OR date='$Date_FourDaysAgo' OR date='$Date_FiveDaysAgo' OR date='$Date_SixDaysAgo' OR date='$Date_SevenDaysAgo')");

You can also use IN

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND date IN ('$Date_Today','$Date_Yesterday','$Date_TwoDaysAgo','$Date_ThreeDaysAgo','$Date_FourDaysAgo','$Date_FiveDaysAgo','$Date_SixDaysAgo','$Date_SevenDaysAgo')");

This works in May 2020 using PDFminer six in Python3.

Installing the package

$ pip install pdfminer.six

Importing the package

from pdfminer.high_level import extract_text

Using a PDF saved on disk

text = extract_text('report.pdf')

Or alternatively:

with open('report.pdf','rb') as f:
    text = extract_text(f)

Using PDF already in memory

If the PDF is already in memory, for example if retrieved from the web with the requests library, it can be converted to a stream using the io library:

import io

response = requests.get(url)
text = extract_text(io.BytesIO(response.content))

Performance and Reliability compared with PyPDF2

PDFminer.six works more reliably than PyPDF2 (which fails with certain types of PDFs), in particular PDF version 1.7

However, text extraction with PDFminer.six is significantly slower than PyPDF2 by a factor of 6.

I timed text extraction with timeit on a 15" MBP (2018), timing only the extraction function (no file opening etc.) with a 10 page PDF and got the following results:

PDFminer.six: 2.88 sec
PyPDF2:       0.45 sec

pdfminer.six also has a huge footprint, requiring pycryptodome which needs GCC and other things installed pushing a minimal install docker image on Alpine Linux from 80 MB to 350 MB. PyPDF2 has no noticeable storage impact.

I am using bootstrap-datepicker and none of above solution worked for me. This answer helped me ..

bootstrap datepicker change date event doesnt fire up when manually editing dates or clearing date

Here is what I applied:

 $('.date-picker').datepicker({
     endDate: new Date(),
     autoclose: true,
 }).on('changeDate', function(ev){
        //my work here
    });

Hope this can help others.

On a button in jQuery mobile, for instance, you can tweak it a bit by applying this style to the image:

.btn-image {
    vertical-align:middle;
    margin:0 0 3px 0;
}

Try this

header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Disposition: attachment;filename=\"filename.xlsx\"");
header("Cache-Control: max-age=0");

Another way of doing this is by generating the select query. Play with this fiddle.

SELECT CONCAT('SELECT ', group_concat(`COLUMN_NAME` SEPARATOR '+'), ' FROM scorecard') 
FROM  `INFORMATION_SCHEMA`.`COLUMNS` 
WHERE `TABLE_SCHEMA` = (select database()) 
AND   `TABLE_NAME`   = 'scorecard'
AND   `COLUMN_NAME` LIKE 'mark%';

The query above will generate another query that will do the selecting for you.

1. Run the above query.
2. Get the result and run that resulting query.

Sample result:

SELECT mark1+mark2+mark3 FROM scorecard

You won't have to manually add all the columns anymore.

That line works as-is in Python 3.

>>> sys.version
'3.2 (r32:88445, Oct 20 2012, 14:09:29) \n[GCC 4.5.2]'
>>> "(%d goals, $%d)" % (self.goals, self.penalties)
'(1 goals, $2)'

You can use this function based on array_walk:

function mapToIDs($array, $id_field_name = 'id')
{
    $result = [];
    array_walk($array, 
        function(&$value, $key) use (&$result, $id_field_name)
        {
            $result[$value[$id_field_name]] = $value;
        }
    );
    return $result;
}

$arr = [0 => ['id' => 'one', 'fruit' => 'apple'], 1 => ['id' => 'two', 'fruit' => 'banana']];
print_r($arr);
print_r(mapToIDs($arr));

It gives:

Array(
    [0] => Array(
        [id] => one
        [fruit] => apple
    )
    [1] => Array(
        [id] => two
        [fruit] => banana
    )
)

Array(
    [one] => Array(
        [id] => one
        [fruit] => apple
    )
    [two] => Array(
        [id] => two
        [fruit] => banana
    )
)

SELECT CONCAT (zipcode, ' - ', city, ', ', state) AS COMBINED FROM TABLE

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

Java has a method for this, "convertStringArrayToIntArray".

String numbers = sc.nextLine();
int[] intArray = convertStringArrayToIntArray(numbers.split(", "));

You should be able to add

target="_blank"

like

<a href="http://www.starfall.com/" target="_blank">Starfall</a>

This will display the three images side by side if the images are not too wide.

<p float="left">
  <img src="/img1.png" width="100" />
  <img src="/img2.png" width="100" /> 
  <img src="/img3.png" width="100" />
</p>

This is old and will probably get buried, but this is my attempt.

I had an issue similar to @Ryan. In some cases, I needed to only check if at least 1 key was in an array, and in some cases, all needed to be present.

So I wrote this function:

/**
 * A key check of an array of keys
 * @param array $keys_to_check An array of keys to check
 * @param array $array_to_check The array to check against
 * @param bool $strict Checks that all $keys_to_check are in $array_to_check | Default: false
 * @return bool
 */
function array_keys_exist(array $keys_to_check, array $array_to_check, $strict = false) {
    // Results to pass back //
    $results = false;

    // If all keys are expected //
    if ($strict) {
        // Strict check //

        // Keys to check count //
        $ktc = count($keys_to_check);
        // Array to check count //
        $atc = count(array_intersect($keys_to_check, array_keys($array_to_check)));

        // Compare all //
        if ($ktc === $atc) {
            $results = true;
        }
    } else {
        // Loose check - to see if some keys exist //

        // Loop through all keys to check //
        foreach ($keys_to_check as $ktc) {
            // Check if key exists in array to check //
            if (array_key_exists($ktc, $array_to_check)) {
                $results = true;
                // We found at least one, break loop //
                break;
            }
        }
    }

    return $results;
}

This was a lot easier than having to write multiple || and && blocks.

pls remove the

HTTP_PROXY HTTPS_PROXY proxy from the npmrc file

Normally you want to perform this check atomically with using the result, so stat() is useless. Instead, open() the file read-only first and use fstat(). If it's a directory, you can then use fdopendir() to read it. Or you can try opening it for writing to begin with, and the open will fail if it's a directory. Some systems (POSIX 2008, Linux) also have an O_DIRECTORY extension to open which makes the call fail if the name is not a directory.

Your method with opendir() is also good if you want a directory, but you should not close it afterwards; you should go ahead and use it.

I know this very old but for future's sake:

I also used a dynamic dns provider. Wanted to test the website (IIS) BEHIND my (home) router. So i thought i use something like this:

my.dynamic.dnss.ip:8080 (because my router's port 80 was used to admin it).

So this seemed to be the only solution.
But: Paypal seemed to not like port 8080: only port 80 and 443 are allowed (don't know why!!)

Another option may be to have your fragment implement View.OnClickListener and override onClick(View v) within your fragment. If you need to have your fragment talk to the activity simply add an interface with desired method(s) and have the activity implement the interface and override its method(s).

public class FragName extends Fragment implements View.OnClickListener { 
    public FragmentCommunicator fComm;
    public ImageButton res1, res2;
    int c;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_test, container, false);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try {
            fComm = (FragmentCommunicator) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " must implement FragmentCommunicator");
        }
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        res1 = (ImageButton) getActivity().findViewById(R.id.responseButton1);
        res1.setOnClickListener(this);
        res2 = (ImageButton) getActivity().findViewById(R.id.responseButton2);
        res2.setOnClickListener(this);
    }
    public void onClick(final View v) { //check for what button is pressed
            switch (v.getId()) {
                case R.id.responseButton1:
                  c *= fComm.fragmentContactActivity(2);
                  break;
                case R.id.responseButton2:
                  c *= fComm.fragmentContactActivity(4);
                  break;
                default:
                  c *= fComm.fragmentContactActivity(100);
                  break;
    }
    public interface FragmentCommunicator{
        public int fragmentContactActivity(int b);
    }



public class MainActivity extends FragmentActivity implements FragName.FragmentCommunicator{
    int a = 10;
    //variable a is update by fragment. ex. use to change textview or whatever else you'd like.

    public int fragmentContactActivity(int b) {
        //update info on activity here
        a += b;
        return a;
    }
}

Two main reasons:

1) mysql-server isn't installed! You have to install it (mysql-server and not mysql-client) and run it.

2) It's installed by default and running. So, it's not possible to run it again through Xampp or Lampp. You have to stop it: sudo service mysql stop

then you can start it through Xampp. It's possible to check if it's running or not with this code: sudo netstat -tap | grep mysql

If you see a result like this: tcp 0 0 localhost:mysql : LISTEN 1043/mysqld

It means that it's running properly.

You could have is_hammer in terms of row["Open"] etc. as follows

def is_hammer(rOpen,rLow,rClose,rHigh):
    return lower_wick_at_least_twice_real_body(rOpen,rLow,rClose) \
       and closed_in_top_half_of_range(rHigh,rLow,rClose)

Then you can use map:

df["isHammer"] = map(is_hammer, df["Open"], df["Low"], df["Close"], df["High"])

String text = String.copyValueOf(data);

or

String text = String.valueOf(data);

is arguably better (encapsulates the new String call).

What you do here is called a JOIN (although you do it implicitly because you select from multiple tables). This means, if you didn't put any conditions in your WHERE clause, you had all combinations of those tables. Only with your condition you restrict your join to those rows where the drink id matches.

But there are still X multiple rows in the result for every drink, if there are X photos with this particular drinks_id. Your statement doesn't restrict which photo(s) you want to have!

If you only want one row per drink, you have to tell SQL what you want to do if there are multiple rows with a particular drinks_id. For this you need grouping and an aggregate function. You tell SQL which entries you want to group together (for example all equal drinks_ids) and in the SELECT, you have to tell which of the distinct entries for each grouped result row should be taken. For numbers, this can be average, minimum, maximum (to name some).

In your case, I can't see the sense to query the photos for drinks if you only want one row. You probably thought you could have an array of photos in your result for each drink, but SQL can't do this. If you only want any photo and you don't care which you'll get, just group by the drinks_id (in order to get only one row per drink):

SELECT name, price, photo
FROM drinks, drinks_photos
WHERE drinks.id = drinks_id 
GROUP BY drinks_id

name     price   photo
fanta    5       ./images/fanta-1.jpg
dew      4       ./images/dew-1.jpg

In MySQL, we also have GROUP_CONCAT, if you want the file names to be concatenated to one single string:

SELECT name, price, GROUP_CONCAT(photo, ',')
FROM drinks, drinks_photos
WHERE drinks.id = drinks_id 
GROUP BY drinks_id

name     price   photo
fanta    5       ./images/fanta-1.jpg,./images/fanta-2.jpg,./images/fanta-3.jpg
dew      4       ./images/dew-1.jpg,./images/dew-2.jpg

However, this can get dangerous if you have , within the field values, since most likely you want to split this again on the client side. It is also not a standard SQL aggregate function.

Introduction

constexpr was not introduced as a way to tell the implementation that something can be evaluated in a context which requires a constant-expression; conforming implementations has been able to prove this prior to C++11.

Something an implementation cannot prove is the intent of a certain piece of code:

• What is it that the developer want to express with this entity?
• Should we blindly allow code to be used in a constant-expression, just because it happens to work?

What would the world be without constexpr?

Let's say you are developing a library and realize that you want to be able to calculate the sum of every integer in the interval (0,N].

int f (int n) {
  return n > 0 ? n + f (n-1) : n;
}

The lack of intent

A compiler can easily prove that the above function is callable in a constant-expression if the argument passed is known during translation; but you have not declared this as an intent - it just happened to be the case.

Now someone else comes along, reads your function, does the same analysis as the compiler; "Oh, this function is usable in a constant-expression!", and writes the following piece of code.

T arr[f(10)]; // freakin' magic

The optimization

You, as an "awesome" library developer, decide that f should cache the result when being invoked; who would want to calculate the same set of values over and over?

int func (int n) { 
  static std::map<int, int> _cached;

  if (_cached.find (n) == _cached.end ()) 
    _cached[n] = n > 0 ? n + func (n-1) : n;

  return _cached[n];
}

The result

By introducing your silly optimization, you just broke every usage of your function that happened to be in a context where a constant-expression was required.

You never promised that the function was usable in a constant-expression, and without constexpr there would be no way of providing such promise.

So, why do we need constexpr?

The primary usage of constexpr is to declare intent.

If an entity isn't marked as constexpr - it was never intended to be used in a constant-expression; and even if it is, we rely on the compiler to diagnose such context (because it disregards our intent).

That's one solution. If you add it to your .bashrc, it'll display the current branch in the console.

# git branch
parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1) /'
}
$PS1="\$(parse_git_branch)$PS1"

However it's pretty limited. But there is a great project called git sh, which is doing exactly that (and much more).

Sort the values:

sorted(data.values())

returns

['a','b']

try use keyup.enter or keydown.enter

  <button type="submit" (keyup.enter)="search(...)">Search</button>

this works for me on chrome 67, firefox 67,

if(!document.hasFocus()) {
    // do stuff
}

I have used Rational Rose and Rational Rhapsody for reverse engineering large projects. I would prefer Rational Rhapsody for getting the UML class files for C++ !

You can't just kill asynctask immediately. In order it to stop you should first cancel it:

task.cancel(true);

and than in asynctask's doInBackground() method check if it's already cancelled:

isCancelled()

and if it is, stop executing it manually.

While both reducebykey and groupbykey will produce the same answer, the reduceByKey example works much better on a large dataset. That's because Spark knows it can combine output with a common key on each partition before shuffling the data.

On the other hand, when calling groupByKey - all the key-value pairs are shuffled around. This is a lot of unnessary data to being transferred over the network.

for more detailed check this below link

TLDR; the solution for me was to restore default settings in visual studio.

I'm on visual studio 2019 community edition and I had this issue for same dll file across different projects that I didn't touch.

After trying out all the answers in this question (as of 2020-07-22 7:13UTC) I decided to repair visual studio installation (backed up my settings beforehand). After installation opened the solutions that had the problem and the problem was gone. After that imported my settings that and the problem came back!! So without repairing visual studio installation again (which takes a few minutes + one restart) I've simply restored VS default settings and then it works. If I end up having time to investigate, I'll edit the answer and pinpoint the underlaying issue

1. Open up a terminal
2. cd <ANDROID_SDK_PATH> (for me on Windows cd C:\Users\Willi\AppData\Local\Android\sdk)
3. cd platform-tools
4. adb shell (this works only if only one emulator is running)
5. cd data/data
6. su (gain super user privileges)
7. cd <PACKAGE_NAME>/databases
8. sqlite3 <DB_NAME>
9. issue SQL statements (important: terminate them with ;, otherwise the statement is not issued and it breaks to a new line instead.)

Note: Use ls (Linux) or dir (Windows) if you need to list directory contents.

I had some problems with this topic too. You have to make sure you define the packages in Spring boot runner class like this example below:

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan({"controller", "service"})
@EntityScan("entity")
@EnableJpaRepositories("repository")
public class Application {

    public static void main(String[] args){
        SpringApplication.run(Application.class, args);
    }

I hope this helps!

You can use the not function rather than the :not selector:

$(".content a").not(this).hide("slow")

Init your autowired component in @PostConstruct method

@Component
public class TestClass {
   private static AutowiredTypeComponent component;

   @Autowired
   private AutowiredTypeComponent autowiredComponent;

   @PostConstruct
   private void init() {
      component = this.autowiredComponent;
   }

   public static void testMethod() {
      component.callTestMethod();
   }
}

It`s work for me! I hope it will be useful to you!

public static RichTextBox RichTextBoxChangeWordColor(ref RichTextBox rtb, string startWord, string endWord, Color color)
{
    rtb.SuspendLayout();
    Point scroll = rtb.AutoScrollOffset;
    int slct = rtb.SelectionIndent;
    int ss = rtb.SelectionStart;
    List<Point> ls = GetAllWordsIndecesBetween(rtb.Text, startWord, endWord, true);
    foreach (var item in ls)
    {
        rtb.SelectionStart = item.X;
        rtb.SelectionLength = item.Y - item.X;
        rtb.SelectionColor = color;
    }
    rtb.SelectionStart = ss;
    rtb.SelectionIndent = slct;
    rtb.AutoScrollOffset = scroll;
    rtb.ResumeLayout(true);
    return rtb;
}

public static List<Point> GetAllWordsIndecesBetween(string intoText, string fromThis, string toThis,bool withSigns = true)
{
    List<Point> result = new List<Point>();
    Stack<int> stack = new Stack<int>();
    bool start = false;
    for (int i = 0; i < intoText.Length; i++)
    {
        string ssubstr = intoText.Substring(i);
        if (ssubstr.StartsWith(fromThis) && ((fromThis == toThis && !start) || !ssubstr.StartsWith(toThis)))
        {
            if (!withSigns) i += fromThis.Length;
            start = true;
            stack.Push(i);
        }
        else if (ssubstr.StartsWith(toThis) )
        {
            if (withSigns) i += toThis.Length;
            start = false;
            if (stack.Count > 0)
            {
                int startindex = stack.Pop();
                result.Add(new Point(startindex,i));
            }
        }
    }
    return result;
}

In my case it worked perfectly

<img style="border-radius: 50%;height: 50px;width: 80px;"  src="<?php echo asset("storage/TeacherImages/{$teacher->profilePic}")?>">

this is used to display image from folder i hope this will help someone looking for this type of code

Benchmarks & introducing Numba

1. Summary

• The accepted answer (scipy.ndimage.interpolation.shift) is the slowest solution listed in this page.
• Numba (@numba.njit) gives some performance boost when array size smaller than ~25.000
• "Any method" equally good when array size large (>250.000).
• The fastest option really depends on
      (1)  Length of your arrays
      (2)  Amount of shift you need to do.
• Below is the picture of the timings of all different methods listed on this page (2020-07-11), using constant shift = 10. As one can see, with small array sizes some methods are use more than +2000% time than the best method.

2. Detailed benchmarks with the best options

• Choose shift4_numba (defined below) if you want good all-arounder

3. Code

3.1 shift4_numba

• Good all-arounder; max 20% wrt. to the best method with any array size
• Best method with medium array sizes: ~ 500 < N < 20.000.
• Caveat: Numba jit (just in time compiler) will give performance boost only if you are calling the decorated function more than once. The first call takes usually 3-4 times longer than the subsequent calls.

import numba

@numba.njit
def shift4_numba(arr, num, fill_value=np.nan):
    if num >= 0:
        return np.concatenate((np.full(num, fill_value), arr[:-num]))
    else:
        return np.concatenate((arr[-num:], np.full(-num, fill_value)))

3.2. shift5_numba

• Best option with small (N <= 300.. 1500) array sizes. Treshold depends on needed amount of shift.
• Good performance on any array size; max + 50% compared to the fastest solution.
• Caveat: Numba jit (just in time compiler) will give performance boost only if you are calling the decorated function more than once. The first call takes usually 3-4 times longer than the subsequent calls.

import numba

@numba.njit
def shift5_numba(arr, num, fill_value=np.nan):
    result = np.empty_like(arr)
    if num > 0:
        result[:num] = fill_value
        result[num:] = arr[:-num]
    elif num < 0:
        result[num:] = fill_value
        result[:num] = arr[-num:]
    else:
        result[:] = arr
    return result

3.3. shift5

• Best method with array sizes ~ 20.000 < N < 250.000
• Same as shift5_numba, just remove the @numba.njit decorator.

4 Appendix

4.1 Details about used methods

• shift_scipy: scipy.ndimage.interpolation.shift (scipy 1.4.1) - The option from accepted answer, which is clearly the slowest alternative.
• shift1: np.roll and out[:num] xnp.nan by IronManMark20 & gzc
• shift2: np.roll and np.put by IronManMark20
• shift3: np.pad and slice by gzc
• shift4: np.concatenate and np.full by chrisaycock
• shift5: using two times result[slice] = x by chrisaycock
• shift#_numba: @numba.njit decorated versions of the previous.

The shift2 and shift3 contained functions that were not supported by the current numba (0.50.1).

4.2 Other test results

4.2.1 Relative timings, all methods

• Relative timings, 10% shift, all methods
• Relative timings, constant shift (10), all methods

4.2.2 Raw timings, all methods

• Raw timings, constant shift (10), all methods
• Raw timings, 10% shift, all methods

4.2.3 Raw timings, few best methods

• Raw timings with small arrays, constant shift (10), few best methods
• Raw timings with small arrays, 10% shift, few best methods
• Raw timings with large arrays, constant shift (10), few best methods
• Raw timings with large arrays, 10% shift, few best methods

"Easiest" way (bash4 only): ls * 2>&- 1>&-.

You've got the ternary syntax x if x else '' - is that what you're after?

Inline items cannot have a width. You have to use display: block or display:inline-block, but the latter is not supported everywhere.

It's a measureable difference.

Run the following:

Create Table #TempTester (id int, col1 varchar(20), value varchar(20))
go

INSERT INTO #TempTester (id, col1, value)
VALUES
(1, 'this is #1', 'abcdefghij')
GO

INSERT INTO #TempTester (id, col1, value)
VALUES
(2, 'this is #2', 'foob'),
(3, 'this is #3', 'abdefghic'),
(4, 'this is #4', 'other'),
(5, 'this is #5', 'zyx'),
(6, 'this is #6', 'zyx'),
(7, 'this is #7', 'zyx'),
(8, 'this is #8', 'klm'),
(9, 'this is #9', 'klm'),
(10, 'this is #10', 'zyx')
GO 10000

CREATE CLUSTERED INDEX ixId ON #TempTester(id)CREATE CLUSTERED INDEX ixId ON #TempTester(id)

CREATE NONCLUSTERED INDEX ixTesting ON #TempTester(value)

Then:

SET SHOWPLAN_XML ON

Then:

SELECT * FROM #TempTester WHERE value LIKE 'abc%'

SELECT * FROM #TempTester WHERE value = 'abcdefghij'

The resulting execution plan shows you that the cost of the first operation, the LIKE comparison, is about 10 times more expensive than the = comparison.

If you can use an = comparison, please do so.

var test = parseInt($("#testid").val());

To answer your updated question you can do

String[] lines = ("Name =              Bob\n" +
        "Age =               27\n" +
        "Occupation =        Student\n" +
        "Status =            Single").split("\n");

for (String line : lines) {
    String[] parts = line.split(" = +");
    System.out.printf("%-19s %s%n", parts[0] + " =", parts[1]);
}

prints

Name =              Bob
Age =               27
Occupation =        Student
Status =            Single

This was totally my bad.

I was using standard node http.request on a part of the code which should be sending requests to only http adresses. Seems like the db had a single https address which was queried with a random interval.

Simply, I was trying to send a http request to https.

FWIW, in case anyone revisits this question later, you might also check what you are handing to your onKeyPress handler function.

I ran into this error when I mistakenly passed onKeyPress(this) instead of onKeyPress(event).

Just something else to check.

This should also work:

ArrayList<String> orig = new ArrayList<String>();
ArrayList<String> copy = (ArrayList<String>) orig.clone()

Using WIN + Q worked for me. Just q alone gave me "command not found" and eventually it jumped back into the git diff insanity.

There is a lot of options to store your data and Android offers you to chose anyone Your data storage options are the following:

Shared Preferences Store private primitive data in key-value pairs. Internal Storage Store private data on the device memory. External Storage Store public data on the shared external storage. SQLite Databases Store structured data in a private database. Network Connection Store data on the web with your own network server

Check here for examples and tuto

If you're page has an Open Graph image, commonly used for social sharing, you can use it to set the background image at runtime with vanilla JavaScript like so:

<script>
  const meta = document.querySelector('[property="og:image"]');
  const body = document.querySelector("body");
  body.style.background = `url(${meta.content})`;
</script>

The above uses document.querySelector and Attribute Selectors to assign meta the first Open Graph image it selects. A similar task is performed to get the body. Finally, string interpolation is used to assign body the background.style the value of the path to the Open Graph image.

If you want the image to cover the entire viewport and stay fixed set background-size like so:

body.style.background = `url(${meta.content}) center center no-repeat fixed`;
body.style.backgroundSize = 'cover';

Using this approach you can set a low-quality background image placeholder using CSS and swap with a high-fidelity image later using an image onload event, thereby reducing perceived latency.

You have two choices, depending on your table order

create table aa (sht int)
create table cc (sht int)
create table cd (sht int)
create table ab (sht int)

-- type 1    
select * from cd
inner join cc on cd.sht = cc.sht
LEFT JOIN ab ON ab.sht = cd.sht
LEFT JOIN aa ON aa.sht = cc.sht

-- type 2
select * from cc
inner join cc on cd.sht = cc.sht
LEFT JOIN ab
LEFT JOIN aa
ON aa.sht = ab.sht
ON ab.sht = cd.sht

it appears there might be a few reasons why there might be no internet connection for an emulator, in my case i was working from home where i have a wireless connection then came into the office and plugged in direct, however although my wireless connection was disconnected it was not disabled resulting in no emulator connection. my understanding is that when it starts up it looks for a network adapter and if there is any conflict here it might result in no internet connection. to resolve go to Start > Settings > Network Connections right click on Wireless Network Connection (if you are not using wireless) and select disable

HTTP_REFERER - sent by the browser, stating the last page the browser viewed!

If you trusting [HTTP_REFERER] for any reason that is important, you should not, since it can be faked easily:

1. Some browsers limit access to not allow HTTP_REFERER to be passed
2. Type a address in the address bar will not pass the HTTP_REFERER
3. open a new browser window will not pass the HTTP_REFERER, because HTTP_REFERER = NULL
4. has some browser addon that blocks it for privacy reasons. Some firewalls and AVs do to.

Try this firefox extension, you'll be able to set any headers you want:

@Master of Celebration:

Firefox:

extensions: refspoof, refontrol, modify headers, no-referer

Completely disable: the option is available in about:config under "network.http.sendRefererHeader" and you want to set this to 0 to disable referer passing.

Google chrome / Chromium:

extensions: noref, spoofy, external noreferrer

Completely disable: Chnage ~/.config/google-chrome/Default/Preferences or ~/.config/chromium/Default/Preferences and set this:

{
   ...
   "enable_referrers": false,
   ...
}

Or simply add --no-referrers to shortcut or in cli:

google-chrome --no-referrers

Opera:

Completely disable: Settings > Preferences > Advanced > Network, and uncheck "Send referrer information"

Spoofing web service:

http://referer.us/

Standalone filtering proxy (spoof any header):

Privoxy

Spoofing http_referer when using wget

‘--referer=url’

Spoofing http_referer when using curl

-e, --referer

Spoofing http_referer wth telnet

telnet www.yoursite.com 80 (press return)
GET /index.html HTTP/1.0 (press return)
Referer: http://www.hah-hah.com (press return)
(press return again)

Install PAR::Packer from CPAN (it is free) and use pp utility.

There is a difference if:

int main()
{
  for(int i(0); i<2; printf("i = post increment in loop %d\n", i++))
  {
    cout << "inside post incement = " << i << endl;
  }


  for(int i(0); i<2; printf("i = pre increment in loop %d\n",++i))
  {
    cout << "inside pre incement = " << i << endl;
  }

  return 0;
}

The result:

inside post incement = 0

i = post increment in loop 0

inside post incement = 1

i = post increment in loop 1

The second for loop:

inside pre incement = 0

i = pre increment in loop 1

inside pre incement = 1

i = pre increment in loop 2

Already @Abubakkar Rangara answered easy way to handle your problem

Alternative is :

String[] result = null;
if(fieldName.endsWith(",")) {                           
String[] result = fieldName.split(",");
    for(int i = 1; i < result.length - 1; i++) {
        result[0] = result[0].concat(result[i]);
    }
}

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

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

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

This should work(with or without 'javascript:' part):

<img onclick="javascript:exportToForm('1.6','55','10','50','1')" src="China-Flag-256.png" />
<script>
function exportToForm(a, b, c, d, e) {
     alert(a, b);
 }
</script>

Add your own class, ex: <div class="sidebar right"></div>, with the CSS as

.sidebar.right { 
    float:right
} 

Below works for me if your exe depend on some dll or certain dependency then you need to set directory path. As mention below exePath mean folder where exe placed along with it's references files.

Exe application creating any temporaray file so it will create in folder mention in processBuilder.directory(...)

**

ProcessBuilder processBuilder = new ProcessBuilder(arguments);
processBuilder.redirectOutput(Redirect.PIPE);
processBuilder.directory(new File(exePath));
process = processBuilder.start();
int waitFlag = process.waitFor();// Wait to finish application execution.
if (waitFlag == 0) {
...
 int returnVal = process.exitValue();
} 

**

You can try Gson convertor, to get the exact conversion like json.stringify

val jsonString:String = jsonObject.toString()
val gson:Gson = GsonBuilder().setPrettyPrinting().create()
val json:JsonElement = gson.fromJson(jsonString,JsonElement.class)
val jsonInString:String= gson.toJson(json)
println(jsonInString)

You do not need to create sub directory. Just create blob container and use file name like the variable filename as below code:

string filename = "document/tech/user-guide.pdf";
CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(ConnectionString);
CloudBlockBlob blob = cloudBlobContainer.GetBlockBlobReference(filename);
blob.StreamWriteSizeInBytes = 20 * 1024;
blob.UploadFromStream(fileStream); // fileStream is System.IO.Stream

You almost did it. You were tricked by the fact that abs(imagem-255) will give a wrong result since your dtype is an unsigned integer. You have to do (255-imagem) in order to keep the integers unsigned:

def inverte(imagem, name):
    imagem = (255-imagem)
    cv2.imwrite(name, imagem)

You can also invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

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

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

I know this is kind of an old question by this one works better.

if(!$('.dropdownName[data-dropdown="' + data["item"][i]["name"] + '"] option[value="'+data['item'][i]['id']+'"]')[0]){
  //Doesn't exist, so it isn't a repeat value being added. Go ahead and append.
  $('.dropdownName[data-dropdown="' + data["item"][i]["name"] + '"]').append(option);
}

As you can see in this example, I am searching by unique tags data-dropdown name and the value of the selected option. Of course you don't need these for these to work but I included them so that others could see you can search multi values, etc.

This is the best and reliable way to do this. Here is a simple example and after that you can develop your custom logic:

//In .ts
public showUploadButton:boolean = false;

if(some logic)
{
    //your logic
    showUploadButton = true;
}

//In template
<button [class]="showUploadButton ? 'btn btn-default': 'btn btn-info'">Upload</button>

For AngularJs you have to use "angular-datatables.min.js" file for datatable settings. You will get this from http://l-lin.github.io/angular-datatables/#/welcome.

After that you can write code like below,

<script>
     var app = angular.module('AngularWayApp', ['datatables']);
</script>

<div ng-app="AngularWayApp" ng-controller="AngularWayCtrl">
  <table id="example" datatable="ng" class="table">
                                    <thead>
                                        <tr>
                                            <th><b>UserID</b></th>
                                            <th><b>Firstname</b></th>
                                            <th><b>Lastname</b></th>
                                            <th><b>Email</b></th>
                                            <th><b>Actions</b></th>

I got the same issue. My solution was a foreach of radio buttons, with the image at the right of it. Since you can only choose a single option at radio, it works (like) a select.

Worket well for me. Hope it can help someone else.

I had same issue, but a bit different.

I was using visual studio 2012. For some reason, only the tests of the initial generated file was running. But tests in another file were not running. Tried out different solutions posted here, did not work.

Finally I figured out that I had a private method in the test class which was the first method inside the class. I just moved the private method after a test method; so now, a method with [TestMethod] attribute is the first method inside the class. Strange, but now it works.

Hope this helps someone someday.

After not finding anything to get around "Object must implement IConvertible" exception when using Zyphrax's answer (except for implementing the interface).. I tried something a little bit unconventional and worked for my situation.

Using the Newtonsoft.Json nuget package...

var castedObject = JsonConvert.DeserializeObject(JsonConvert.SerializeObject(myObject), myType);

ALTER TABLE TABLE_NAME ADD (COLUMN_NAME_NEW varchar2(4000 char));
update TABLE_NAME set COLUMN_NAME_NEW = COLUMN_NAME;

ALTER TABLE TABLE_NAME DROP COLUMN COLUMN_NAME;
ALTER TABLE TABLE_NAME rename column COLUMN_NAME_NEW to COLUMN_NAME;

Personal opinion: Use them only where they are required. (See TheTXI's answer above for the required list.)

Since the compiler doesn't require them, you can put them all over, but why? The compiler won't tell you where you forgot one, so you'll end up with inconsistent use.

[This opinion is specific to SQL Server. Other databases may have more-stringent requirements. If you're writing SQL to run on multiple databases, your requirements may vary.]

tpdi stated above, "in a script, as you're sending more than one statement, you need it." That's actually not correct. You don't need them.

PRINT 'Semicolons are optional'
PRINT 'Semicolons are optional'
PRINT 'Semicolons are optional';
PRINT 'Semicolons are optional';

Output:

Semicolons are optional
Semicolons are optional
Semicolons are optional
Semicolons are optional

The first example demonstrates event delegation. The event handler is bound to an element higher up the DOM tree (in this case, the document) and will be executed when an event reaches that element having originated on an element matching the selector.

This is possible because most DOM events bubble up the tree from the point of origin. If you click on the #id element, a click event is generated that will bubble up through all of the ancestor elements (side note: there is actually a phase before this, called the 'capture phase', when the event comes down the tree to the target). You can capture the event on any of those ancestors.

The second example binds the event handler directly to the element. The event will still bubble (unless you prevent that in the handler) but since the handler is bound to the target, you won't see the effects of this process.

By delegating an event handler, you can ensure it is executed for elements that did not exist in the DOM at the time of binding. If your #id element was created after your second example, your handler would never execute. By binding to an element that you know is definitely in the DOM at the time of execution, you ensure that your handler will actually be attached to something and can be executed as appropriate later on.

i agree with you about alternative solutions which you mentioned above

1. Use POST instead of GET;
2. Transform the List into a JSON string and pass it to the service.

and its true that you can't add List to MultiValuedMap because of its impl class MultivaluedMapImpl have capability to accept String Key and String Value. which is shown in following figure

still you want to do that things than try following code.

Controller Class

package net.yogesh.test;

import java.util.List;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;

import com.google.gson.Gson;

@Path("test")
public class TestController {
       @Path("testMethod")
       @GET
       @Produces("application/text")
       public String save(
               @QueryParam("list") List<String> list) {

           return  new Gson().toJson(list) ;
       }
}

Client Class

package net.yogesh.test;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import javax.ws.rs.core.MultivaluedMap;

import com.sun.jersey.api.client.ClientResponse;

import com.sun.jersey.api.client.config.DefaultClientConfig;
import com.sun.jersey.core.util.MultivaluedMapImpl;

public class Client {
    public static void main(String[] args) {
        String op = doGet("http://localhost:8080/JerseyTest/rest/test/testMethod");
        System.out.println(op);
    }

    private static String doGet(String url){
        List<String> list = new ArrayList<String>();
        list = Arrays.asList(new String[]{"string1,string2,string3"});

        MultivaluedMap<String, String> params = new MultivaluedMapImpl();
        String lst = (list.toString()).substring(1, list.toString().length()-1);
        params.add("list", lst);

        ClientConfig config = new DefaultClientConfig();
        com.sun.jersey.api.client.Client client = com.sun.jersey.api.client.Client.create(config);
        WebResource resource = client.resource(url);

        ClientResponse response = resource.queryParams(params).type("application/x-www-form-urlencoded").get(ClientResponse.class);
        String en = response.getEntity(String.class);
        return en;
    }
}

hope this'll help you.

If you guys still interested, here is my workaround based on Guzzle middleware feature:

1. Create JsonAwaraResponse that will decode JSON response by Content-Type HTTP header, if not - it will act as standard Guzzle Response:

   <?php
   
   namespace GuzzleHttp\Psr7;
   
   
   class JsonAwareResponse extends Response
   {
       /**
        * Cache for performance
        * @var array
        */
       private $json;
   
       public function getBody()
       {
           if ($this->json) {
               return $this->json;
           }
           // get parent Body stream
           $body = parent::getBody();
   
           // if JSON HTTP header detected - then decode
           if (false !== strpos($this->getHeaderLine('Content-Type'), 'application/json')) {
               return $this->json = \json_decode($body, true);
           }
           return $body;
       }
   }
   

2. Create Middleware which going to replace Guzzle PSR-7 responses with above Response implementation:

   <?php
   
   $client = new \GuzzleHttp\Client();
   
   /** @var HandlerStack $handler */
   $handler = $client->getConfig('handler');
   $handler->push(\GuzzleHttp\Middleware::mapResponse(function (\Psr\Http\Message\ResponseInterface $response) {
       return new \GuzzleHttp\Psr7\JsonAwareResponse(
           $response->getStatusCode(),
           $response->getHeaders(),
           $response->getBody(),
           $response->getProtocolVersion(),
           $response->getReasonPhrase()
       );
   }), 'json_decode_middleware');
   

After this to retrieve JSON as PHP native array use Guzzle as always:

$jsonArray = $client->get('http://httpbin.org/headers')->getBody();

Tested with guzzlehttp/guzzle 6.3.3

You could use @> operator to do this something like

SELECT info->>'name'
FROM rabbits
WHERE info->'food' @> '"carrots"';

I suggest, you use the MaskedTextBox: http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.aspx

If you check the info on python.org, you can see this summary:

Version Time (seconds)
Basic loop 3.47
Eliminate dots 2.45
Local variable & no dots 1.79
Using map function 0.54

But you really should read the above article in details to understand the cause of the performance difference.

I also strongly suggest you should time your code by using timeit. At the end of the day, there can be a situation where, for example, you may need to break out of for loop when a condition is met. It could potentially be faster than finding out the result by calling map.

There are many ways as as outlined above. You can also do this in onNavigationDrawerSelected()in your DrawerActivity

public void setTitle(final String title){
    ((TextView)findViewById(R.id.toolbar_title)).setText(title);
}

@Override
public void onNavigationDrawerItemSelected(int position) {
    // update the main content by replacing fragments
    fragment = null;
    String title = null;
    switch(position){

    case 0:
        fragment = new HomeFragment();
        title = "Home";
        break;
    case 1:
        fragment = new ProfileFragment();
        title = ("Find Work");
        break;
    ...
    }
    if (fragment != null){

        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager
        .beginTransaction()
        .replace(R.id.container,
                fragment).commit();

        //The key is this line
        if (title != null && findViewById(R.id.toolbar_title)!= null ) setTitle(title);
    }
}

DateTime has a Subtract method and an overloaded - operator for just such an occasion:

DateTime now = DateTime.UtcNow;
TimeSpan difference = now.Subtract(otherTime); // could also write `now - otherTime`
if (difference.TotalSeconds > 5) { ... }

Configuration conf = new Configuration();
conf.set("fs.defaultFS", "hdfs://nameNode:9000");
FileSystem fs = FileSystem.get(conf);

set fs.defaultFS works for me! Hadoop-2.8.1

Well i do it some thing like this.

        NormalWaitDialog/*your wait form*/ _frmWaitDialog = null;


        //Btn Load Click Event
        _frmWaitDialog = new NormalWaitDialog();
        _frmWaitDialog.Shown += async (s, ee) =>
        {
            await Task.Run(() =>
           {
               // DO YOUR STUFF HERE 

               //Made long running loop to imitate lengthy process
               int x = 0;
               for (int i = 0; i < int.MaxValue; i++)
               {
                   x += i;
               }

           }).ConfigureAwait(true);
            _frmWaitDialog.Close();
        };
        _frmWaitDialog.ShowDialog(this);

Use a for loop and set each one in turn.

    public static void Copy(String SourceFile, String TargetFile)
    {

        FileStream fis = null;
        FileStream fos = null;

            try
            {
                Console.Write("## Try No. " + a + " : (Write from " + SourceFile + " to " + TargetFile + ")\n");

                fis = new FileStream(SourceFile, FileMode.Open, FileAccess.ReadWrite);
                fos = new FileStream(TargetFile, FileMode.Create, FileAccess.ReadWrite);

                int intbuffer = 5242880;
                byte[] b = new byte[intbuffer];

                int i;
                while ((i = fis.Read(b, 0, intbuffer)) > 0)
                {
                    fos.Write(b, 0, i);
                }

                Console.Write("Writing file : " + TargetFile + " is successful.\n");

                break;
            }
            catch (Exception e)
            {
                Console.Write("Writing file : " + TargetFile + " is unsuccessful.\n");
                Console.Write(e);
            }
            finally
            {
                if (fis != null)
                {
                    fis.Close();
                }
                if (fos != null)
                {
                    fos.Close();
                }
            }
    }

The code above will read a big file and write to a new big file. The "intbuffer" value can be set in multiple of 1024. While both source and target file are open, it reads the big file by bytes and write to the new target file by bytes. It will not go out of memory.

I faced the same 415 http error when sending objects, serialized into JSON, via PUT/PUSH requests to my JAX-rs services, in other words my server was not able to de-serialize the objects from JSON. In my case, the server was able to serialize successfully the same objects in JSON when sending them into its responses.

As mentioned in the other responses I have correctly set the Accept and Content-Type headers to application/json, but it doesn't suffice.

Solution

I simply forgot a default constructor with no parameters for my DTO objects. Yes this is the same reasoning behind @Entity objects, you need a constructor with no parameters for the ORM to instantiate objects and populate the fields later.

Adding the constructor with no parameters to my DTO objects solved my issue. Here follows an example that resembles my code:

Wrong

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {
    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

Right

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {

    public NumberDTO() {
    }

    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

I lost hours, I hope this'll save yours ;-)

%lld is the standard C99 way, but that doesn't work on the compiler that I'm using (mingw32-gcc v4.6.0). The way to do it on this compiler is: %I64d

So try this:

if(e%n==0)printf("%15I64d -> %1.16I64d\n",e, 4*pi);

and

scanf("%I64d", &n);

The only way I know of for doing this in a completely portable way is to use the defines in <inttypes.h>.

In your case, it would look like this:

scanf("%"SCNd64"", &n);
//...    
if(e%n==0)printf("%15"PRId64" -> %1.16"PRId64"\n",e, 4*pi);

It really is very ugly... but at least it is portable.

Edit your AndroidManifest.xml to add RECEIVE_BOOT_COMPLETED permission

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

Edit your AndroidManifest.xml application-part for below Permission

<receiver android:enabled="true" android:name=".BootUpReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

Now write below in Activity.

public class BootUpReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent i = new Intent(context, MyActivity.class);  
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);  
    }
}

If you are using a Form Control, you can get the same property as ActiveX by using OLEFormat.Object property of the Shape Object. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.

Dim opt As OptionButton

With Sheets("Sheet1") ' Try to be always explicit
    Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
    Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With

But then again, you really don't need to know the value.
If you use Form Control, you associate a Macro or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.

For example you have 2 Form Control Option Buttons.

Sub CheckOptions()
    Select Case Application.Caller
    Case "Option Button 1"
    ' Action for option button 1
    Case "Option Button 2"
    ' Action for option button 2
    End Select
End Sub

In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller.
This way, no need to check whether the option button value is true or false.

Regexes for ipv6 can get really tricky when you consider addresses with embedded ipv4 and addresses that are compressed, as you can see from some of these answers.

The open-source IPAddress Java library will validate all standard representations of IPv6 and IPv4 and also supports prefix-length (and validation of such). Disclaimer: I am the project manager of that library.

Code example:

        try {
            IPAddressString str = new IPAddressString("::1");
            IPAddress addr = str.toAddress();
            if(addr.isIPv6() || addr.isIPv6Convertible()) {
                IPv6Address ipv6Addr = addr.toIPv6();
            }
            //use address
        } catch(AddressStringException e) {
            //e.getMessage has validation error
        }

in objective C:

NSData *tmpData;
NSString *tmpString = [NSString stringWithFormat:@"%@", tmpData];
NSLog(tmpString)

I wasn't able to fix the problem OpenCV either, but a video4linux (V4L2) workaround does work with OpenCV when using Linux. At least, it does on my Raspberry Pi with Rasbian and my cheap webcam. This is not as solid, light and portable as you'd like it to be, but for some situations it might be very useful nevertheless.

Make sure you have the v4l2-ctl application installed, e.g. from the Debian v4l-utils package. Than run (before running the python application, or from within) the command:

v4l2-ctl -d /dev/video1 -c exposure_auto=1 -c exposure_auto_priority=0 -c exposure_absolute=10

It overwrites your camera shutter time to manual settings and changes the shutter time (in ms?) with the last parameter to (in this example) 10. The lower this value, the darker the image.

As slashnick & bobince mention, hasChildNodes() will return true for whitespace (text nodes). However, I didn't want this behaviour, and this worked for me :)

element.getElementsByTagName('*').length > 0

Edit: for the same functionality, this is a better solution:

 element.children.length > 0

children[] is a subset of childNodes[], containing elements only.

Compatibility

Only set the width or height, and it will scale the other automatically. And yes you can use a percentage.

The first part can be done, but requires JavaScript, so might not work for all users.

A flexible solution with Java 8 lambda that lets you provide a Consumer that will process the output (eg. log it) line by line. run() is a one-liner with no checked exceptions thrown. Alternatively to implementing Runnable, it can extend Thread instead as other answers suggest.

class StreamGobbler implements Runnable {
    private InputStream inputStream;
    private Consumer<String> consumeInputLine;

    public StreamGobbler(InputStream inputStream, Consumer<String> consumeInputLine) {
        this.inputStream = inputStream;
        this.consumeInputLine = consumeInputLine;
    }

    public void run() {
        new BufferedReader(new InputStreamReader(inputStream)).lines().forEach(consumeInputLine);
    }
}

You can then use it for example like this:

public void runProcessWithGobblers() throws IOException, InterruptedException {
    Process p = new ProcessBuilder("...").start();
    Logger logger = LoggerFactory.getLogger(getClass());

    StreamGobbler outputGobbler = new StreamGobbler(p.getInputStream(), System.out::println);
    StreamGobbler errorGobbler = new StreamGobbler(p.getErrorStream(), logger::error);

    new Thread(outputGobbler).start();
    new Thread(errorGobbler).start();
    p.waitFor();
}

Here the output stream is redirected to System.out and the error stream is logged on the error level by the logger.

    public static bool[] Convert(int[] input, int length)
    {
        var ret = new bool[length];
        var siz = sizeof(int) * 8;
        var pow = 0;
        var cur = 0;

        for (var a = 0; a < input.Length && cur < length; ++a)
        {

try this

var latlng = new google.maps.LatLng(51.4975941, -0.0803232);
var map = new google.maps.Map(document.getElementById('map'), {
    center: latlng,
    zoom: 11,
    mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
    position: latlng,
    map: map,
    title: 'Set lat/lon values for this property',
    draggable: true
});

google.maps.event.addListener(marker, 'dragend', function (event) {
    document.getElementById("latbox").value = this.getPosition().lat();
    document.getElementById("lngbox").value = this.getPosition().lng();
});

That's because your first code snippet is not performing initialization, but assignment:

char myarray[4] = "abc";  // Initialization.

myarray = "abc";          // Assignment.

And arrays are not directly assignable in C.

The name myarray actually resolves to the address of its first element (&myarray[0]), which is not an lvalue, and as such cannot be the target of an assignment.

This also happens if you are trying to write a file, but your path is a folder.

This can happen easily by mistake.

To defend against that, use:

import os

path = r"my/path/to/file.txt"
assert os.path.isfile(path)
with open(path, "r") as f:
    pass

The assertion will fail if your path is actually a folder.

For substracting in moment.js:

moment().subtract(1, 'months').format('MMM YYYY');

Documentation:

http://momentjs.com/docs/#/manipulating/subtract/

Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).

  moment().subtract('seconds', 1); // Deprecated in 2.8.0
  moment().subtract(1, 'seconds');

As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.

  moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
  moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8

With VS2010+ there is a plugin solution: Line Endings Unifier.

With the plugin installed you can right click files and folders in the solution explorer and invoke the menu item Unify Line Endings in this file

Configuration for this is available via

Tools -> Options -> Line Endings Unifier.

The default file extension list that is included is pretty narrow:

 .cpp; .c; .h; .hpp; .cs; .js; .vb; .txt;

Might want to use something like:

 .cpp; .c; .h; .hpp; .cs; .js; .vb; .txt; .scss; .coffee; .ts; .jsx; .markdown; .config

This should work for you:

    $('.SeeMore2').click(function(){
        var $this = $(this);
        $this.toggleClass('SeeMore2');
        if($this.hasClass('SeeMore2')){
            $this.text('See More');         
        } else {
            $this.text('See Less');
        }
});

If your AWK doesn't have strftime():

ping host | perl -nle 'print scalar(localtime), " ", $_'

To redirect it to a file, use standard shell redirection and turn off output buffering:

ping host | perl -nle 'BEGIN {$|++} print scalar(localtime), " ", $_' > outputfile

If you want ISO8601 format for the timestamp:

ping host | perl -nle 'use Time::Piece; BEGIN {$|++} print localtime->datetime, " ", $_' > outputfile

Another one with an SVG as inline overlay-image (note: if you use # inside the svg-code you have to urlencode that!):

background: url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><path fill="rgba(255, 255, 255, 0.4)" d="M0 0h1v1H0z"/></svg>')
                no-repeat center center/cover, 
            url('overlayed-image.jpg') no-repeat center center/cover;

Maybe you should try removing "new" keyword and see if works. Because last time I got this error when I tried creating Typeface something like this:

Typeface typeface = new Typeface().create("Arial",Typeface.BOLD);

How about

<img style="display: none;" src="a.gif">

That will disable the display completely, and not leave a placeholder

My project is built in Yii & uses the Bootstrap-Yii plugin, so this answer is only relevant if you're using Yii.

The above fix did work but only after the first time the modal was shown. The first time it came up empty. I think that's because after my initiation of the code Yii calls the hide function of the modal thereby clearing out my initiation variables.

I found that putting the removeData call immediately before the code that launched the modal did the trick. So my code is structured like this...

$ ("#myModal").removeData ('modal');
$ ('#myModal').modal ({remote : 'path_to_remote'});

I usually use a helper class I once wrote for this task:

import java.util.zip.*;
import java.io.*;

public class ZipExample {
    public static void main(String[] args){
        ZipHelper zippy = new ZipHelper();
        try {
            zippy.zipDir("folderName","test.zip");
        } catch(IOException e2) {
            System.err.println(e2);
        }
    }
}

class ZipHelper  
{
    public void zipDir(String dirName, String nameZipFile) throws IOException {
        ZipOutputStream zip = null;
        FileOutputStream fW = null;
        fW = new FileOutputStream(nameZipFile);
        zip = new ZipOutputStream(fW);
        addFolderToZip("", dirName, zip);
        zip.close();
        fW.close();
    }

    private void addFolderToZip(String path, String srcFolder, ZipOutputStream zip) throws IOException {
        File folder = new File(srcFolder);
        if (folder.list().length == 0) {
            addFileToZip(path , srcFolder, zip, true);
        }
        else {
            for (String fileName : folder.list()) {
                if (path.equals("")) {
                    addFileToZip(folder.getName(), srcFolder + "/" + fileName, zip, false);
                } 
                else {
                     addFileToZip(path + "/" + folder.getName(), srcFolder + "/" + fileName, zip, false);
                }
            }
        }
    }

    private void addFileToZip(String path, String srcFile, ZipOutputStream zip, boolean flag) throws IOException {
        File folder = new File(srcFile);
        if (flag) {
            zip.putNextEntry(new ZipEntry(path + "/" +folder.getName() + "/"));
        }
        else {
            if (folder.isDirectory()) {
                addFolderToZip(path, srcFile, zip);
            }
            else {
                byte[] buf = new byte[1024];
                int len;
                FileInputStream in = new FileInputStream(srcFile);
                zip.putNextEntry(new ZipEntry(path + "/" + folder.getName()));
                while ((len = in.read(buf)) > 0) {
                    zip.write(buf, 0, len);
                }
            }
        }
    }
}

Parsing multiple output

Introduction

So your myscript output 3 lines, could look like:

myscript() { echo $'abc\ndef\nghi'; }

or

myscript() { local i; for i in abc def ghi ;do echo $i; done ;}

Ok this is a function, not a script (no need of path ./), but output is same

myscript
abc
def
ghi

Considering result code

To check for result code, test function will become:

myscript() { local i;for i in abc def ghi ;do echo $i;done;return $((RANDOM%128));}

1. Storing multiple output in one single variable, showing newlines

Your operation is correct:

RESULT=$(myscript)

About result code, you could add:

RCODE=$?

even in same line:

RESULT=$(myscript) RCODE=$?

Then

echo $RESULT 
abc def ghi

echo "$RESULT"
abc
def
ghi

echo ${RESULT@Q}
$'abc\ndef\nghi'

printf "%q\n" "$RESULT"
$'abc\ndef\nghi'

but for showing variable definition, use declare -p:

declare -p RESULT
declare -- RESULT="abc
def
ghi"

2. Parsing multiple output in array, using mapfile

Storing answer into myvar variable:

mapfile -t myvar < <(myscript)
echo ${myvar[2]}
ghi

Showing $myvar:

declare -p myvar
declare -a myvar=([0]="abc" [1]="def" [2]="ghi")

Considering result code

In case you have to check for result code, you could:

RESULT=$(myscript) RCODE=$?
mapfile -t myvar <<<"$RESULT"

3. Parsing multiple output by consecutives read in command group

{ read firstline; read secondline; read thirdline;} < <(myscript)
echo $secondline
def

Showing variables:

declare -p firstline secondline thirdline
declare -- firstline="abc"
declare -- secondline="def"
declare -- thirdline="ghi"

I often use:

{ read foo;read foo total use free foo ;} < <(df -k /)

Then

declare -p use free total
declare -- use="843476"
declare -- free="582128"
declare -- total="1515376"

Considering result code

Same prepended step:

RESULT=$(myscript) RCODE=$?
{ read firstline; read secondline; read thirdline;} <<<"$RESULT"

declare -p firstline secondline thirdline RCODE
declare -- firstline="abc"
declare -- secondline="def"
declare -- thirdline="ghi"
declare -- RCODE="50"

foreach (glob("classes/*.php") as $filename)
{
    include $filename;
}

The use of http.createClient is now deprecated. You can pass Headers in options collection as below.

var options = { 
    hostname: 'example.com',
    path: '/somePath.php',
    method: 'GET',
    headers: {'Cookie': 'myCookie=myvalue'}
};
var results = ''; 
var req = http.request(options, function(res) {
    res.on('data', function (chunk) {
        results = results + chunk;
        //TODO
    }); 
    res.on('end', function () {
        //TODO
    }); 
});

req.on('error', function(e) {
        //TODO
});

req.end();

Someone should mark Johannes Weiß's comment as the answer to this question. That is exactly why xml documents can't just be loaded in a DOM Document class.

http://en.wikipedia.org/wiki/Byte_order_mark

You can do the following:

<form action="/" onsubmit="if(document.getElementById('agree').checked) { return true; } else { alert('please agree'); return false; }">
    <input type="checkbox" name="checkbox" value="check" id="agree" />
    <input type="submit" name="email_submit" value="submit" />
</form>?

Here is a working demo - http://jsfiddle.net/Ccr2x/

Just install

conda install graphviz

then install

conda install -c conda-forge pydotplus

Use jQuery multiple-selector if the only difference between the two functions is the value of the button being triggered.

$("#button_1, #button_2").on("click", function(e) {
    e.preventDefault();
    $.ajax({type: "POST",
        url: "/pages/test/",
        data: { id: $(this).val(), access_token: $("#access_token").val() },
        success:function(result) {
          alert('ok');
        },
        error:function(result) {
          alert('error');
        }
    });
});

This jsPerf test suggests that find() is faster. I created a more thorough test, and it still looks as though find() outperforms children().

Update: As per tvanfosson's comment, I created another test case with 16 levels of nesting. find() is only slower when finding all possible divs, but find() still outperforms children() when selecting the first level of divs.

children() begins to outperform find() when there are over 100 levels of nesting and around 4000+ divs for find() to traverse. It's a rudimentary test case, but I still think that find() is faster than children() in most cases.

I stepped through the jQuery code in Chrome Developer Tools and noticed that children() internally makes calls to sibling(), filter(), and goes through a few more regexes than find() does.

find() and children() fulfill different needs, but in the cases where find() and children() would output the same result, I would recommend using find().

If you are deliberately displaying it for the end user, wrap the JSON text in <PRE> and <CODE> tags, e.g.:

<html>
<body>
<pre>
<code>
[
    {
        color: "red",
        value: "#f00"
    },
    {
        color: "green",
        value: "#0f0"
    },
    {
        color: "blue",
        value: "#00f"
    },
    {
        color: "cyan",
        value: "#0ff"
    },
    {
        color: "magenta",
        value: "#f0f"
    },
    {
        color: "yellow",
        value: "#ff0"
    },
    {
        color: "black",
        value: "#000"
    }
]

</code>
</pre>
</body>
</html>

Otherwise I would use JSON Viewer.

The ISO C99 standard specifies that these macros must only be defined if explicitly requested.

#define __STDC_FORMAT_MACROS
#include <inttypes.h>

... now PRIu64 will work

Arrays must have zero based integer indexes in JavaScript. So:

var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);

Or maybe you want to use objects (which are associative arrays):

var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);

which is equivalent to:

var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);

It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.

As your edit points out, you can use two separate branches to store the two separate directories. This does keep them both in the same repository, but you still can't have commits spanning both directory trees. If you have a change in one that requires a change in the other, you'll have to do those as two separate commits, and you open up the possibility that a pair of checkouts of the two directories can go out of sync.

If you want to treat the pair of directories as one unit, you can use 'wordpress/wp-content' as the root of your repo and use .gitignore file at the top level to ignore everything but the two subdirectories of interest. This is probably the most reasonable solution at this point.

Sparse checkouts have been allegedly coming for two years now, but there's still no sign of them in the git development repo, nor any indication that the necessary changes will ever arrive there. I wouldn't count on them.

You've mentioned that they each have their own machines, but if they need to log onto a co-workers machine, and then use the file, saving it through "C:\Users\Public\Desktop\" will make it available to different usernames.

Public Sub SaveToDesktop()
    ThisWorkbook.SaveAs Filename:="C:\Users\Public\Desktop\" & ThisWorkbook.Name & "_copy", _ 
    FileFormat:=xlOpenXMLWorkbookMacroEnabled
End Sub

I'm not sure whether this would be a requirement, but may help!

My problem was also solved by the Single Quotes around the variable name

do {
    printf("Word length... ");
    scanf("%d", &wdlen);
} while(wdlen<2);

A do-while loop guarantees the execution of the loop at least once because it checks the loop condition AFTER the loop iteration. Therefore it'll print the string and call scanf, thus updating the wdlen variable.

while(wdlen<2){
    printf("Word length... ");
    scanf("%d", &wdlen);
} 

As for the while loop, it evaluates the loop condition BEFORE the loop body is executed. wdlen probably starts off as more than 2 in your code that's why you never reach the loop body.

You can improve read speed by using a BufferedStream, like this:

using (FileStream fs = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
using (BufferedStream bs = new BufferedStream(fs))
using (StreamReader sr = new StreamReader(bs))
{
    string line;
    while ((line = sr.ReadLine()) != null)
    {

    }
}

March 2013 UPDATE

I recently wrote code for reading and processing (searching for text in) 1 GB-ish text files (much larger than the files involved here) and achieved a significant performance gain by using a producer/consumer pattern. The producer task read in lines of text using the BufferedStream and handed them off to a separate consumer task that did the searching.

I used this as an opportunity to learn TPL Dataflow, which is very well suited for quickly coding this pattern.

Why BufferedStream is faster

A buffer is a block of bytes in memory used to cache data, thereby reducing the number of calls to the operating system. Buffers improve read and write performance. A buffer can be used for either reading or writing, but never both simultaneously. The Read and Write methods of BufferedStream automatically maintain the buffer.

December 2014 UPDATE: Your Mileage May Vary

Based on the comments, FileStream should be using a BufferedStream internally. At the time this answer was first provided, I measured a significant performance boost by adding a BufferedStream. At the time I was targeting .NET 3.x on a 32-bit platform. Today, targeting .NET 4.5 on a 64-bit platform, I do not see any improvement.

Related

I came across a case where streaming a large, generated CSV file to the Response stream from an ASP.Net MVC action was very slow. Adding a BufferedStream improved performance by 100x in this instance. For more see Unbuffered Output Very Slow

You can use peek to do that.

List<Fruit> newList = fruits.stream()
    .peek(f -> f.setName(f.getName() + "s"))
    .collect(Collectors.toList());

MS Expression Encoder can do mp4/h.264. not sure about ogg though.

You can also use npmlog by issacs, recommended in https://npmjs.org/doc/coding-style.html.

You can find this module here https://github.com/isaacs/npmlog

Although it might be heresy in today's world - in the past you would do the following non-css code. This works in everything up to and including today's browsers but - as I have said - it is heresy in today's world:

<center>
<table>
   ...
</table>
</center>

What you need is some way to tell that you want to center a table and the person is using an older browser. Then insert the "<center>" commands around the table. Otherwise - use css.

Surprisingly - if you want to center everything in the BODY area - you just can use the standard

text-align: center;

css command and in IE8 (at least) it will center everything on the page including tables.

This was for my own project and I'm sharing it here too.

This simple script allows you to uncheck an already checked radio button. Works on all javascript enabled browsers.

var allRadios = document.getElementsByName('re');_x000D_
var booRadio;_x000D_
var x = 0;_x000D_
for(x = 0; x < allRadios.length; x++){_x000D_
  allRadios[x].onclick = function() {_x000D_
    if(booRadio == this){_x000D_
      this.checked = false;_x000D_
      booRadio = null;_x000D_
    } else {_x000D_
      booRadio = this;_x000D_
    }_x000D_
  };_x000D_
}

<input type='radio' class='radio-button' name='re'>_x000D_
<input type='radio' class='radio-button' name='re'>_x000D_
<input type='radio' class='radio-button' name='re'>

An alternative using eval so avoiding use of a subshell:

sudo -s eval 'whoami; whoami'

Note: The other answers using sudo -s fail because the quotes are being passed on to bash and run as a single command so need to strip quotes with eval. eval is better explained is this SO answer

Quoting within the commands is easier too:

$ sudo -s eval 'whoami; whoami; echo "end;"'
root
root
end;

And if the commands need to stop running if one fails use double-ampersands instead of semi-colons:

$ sudo -s eval 'whoami && whoamit && echo "end;"'
root
/bin/bash: whoamit: command not found

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.
