The code works well for me.

$str = substr($str ,-(strlen($str)-1));

Maybe, contribute with answers too.

You can also get an updated version of the Eclipse's ADT plugin (based on an unreleased 24.2.0 version) that I managed to patch and compile at https://github.com/khaledev/ADT.

I got the same error when I installed Laravel version 8.27.0: The error is as follow:

But when I saw my app/Providers/RouteServiceProvider.php I have namespaces inside my boot method, then I just uncommented this => "protected $namespace = 'App\Http\Controllers';"

Now My Project is working:

$sUrl = 'http://www.linktopage.com/login/';
$params = array('http' => array(
    'method'  => 'POST',
    'content' => 'username=admin195&password=d123456789'
));

$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if(!$fp) {
    throw new Exception("Problem with $sUrl, $php_errormsg");
}

$response = @stream_get_contents($fp);
if($response === false) {
    throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}

More detail, which may perhaps be helpful to someone:

Due to my own explorations, I now know how to set environment variables in 7 of 8 different ways. I was trying to get an envar through to an application I'm developing under Xcode. I set "tracer" envars using these different methods to tell me which ones get it into the scope of my application. From the below, you can see that editing the "scheme" in Xcode to add arguments works, as does "putenv". What didn't set it in that scope: ~/.MACOS/environment.plist, app-specific plist, .profile, and adding a build phase to run a custom script (I found another way in Xcode [at least] to set one but forgot what I called the tracer and can't find it now; maybe it's on another machine....)

GPU_DUMP_DEVICE_KERNEL is 3

GPU_DUMP_TRK_ENVPLIST is (null)

GPU_DUMP_TRK_APPPLIST is (null)

GPU_DUMP_TRK_DOTPROFILE is (null)

GPU_DUMP_TRK_RUNSCRIPT is (null)

GPU_DUMP_TRK_SCHARGS is 1

GPU_DUMP_TRK_PUTENV is 1

... on the other hand, if I go into Terminal and say "set", it seems the only one it gets is the one from .profile (I would have thought it would pick up environment.plist also, and I'm sure once I did see a second tracer envar in Terminal, so something's probably gone wonky since then. Long day....)

}

If you can use .NET 4 or higher than use HasFlag() method

examples

letter.HasFlag(Letters.A | Letters.B) // both A and B must be set

same as

letter.HasFlag(Letters.AB)

I'll throw mine in the mix:

https://gist.github.com/btm1/6802312

this evaluates the if statement once and adds no watch listener BUT you can add an additional attribute to the element that has the set-if called wait-for="somedata.prop" and it will wait for that data or property to be set before evaluating the if statement once. that additional attribute can be very handy if you're waiting for data from an XHR request.

angular.module('setIf',[]).directive('setIf',function () {
    return {
      transclude: 'element',
      priority: 1000,
      terminal: true,
      restrict: 'A',
      compile: function (element, attr, linker) {
        return function (scope, iterStartElement, attr) {
          if(attr.waitFor) {
            var wait = scope.$watch(attr.waitFor,function(nv,ov){
              if(nv) {
                build();
                wait();
              }
            });
          } else {
            build();
          }

          function build() {
            iterStartElement[0].doNotMove = true;
            var expression = attr.setIf;
            var value = scope.$eval(expression);
            if (value) {
              linker(scope, function (clone) {
                iterStartElement.after(clone);
                clone.removeAttr('set-if');
                clone.removeAttr('wait-for');
              });
            }
          }
        };
      }
    };
  });

Just to extend the answers a bit with what to do with the parsed object:

# JSON Parsing example
require "rubygems" # don't need this if you're Ruby v1.9.3 or higher
require "json"

string = '{"desc":{"someKey":"someValue","anotherKey":"value"},"main_item":{"stats":{"a":8,"b":12,"c":10}}}'
parsed = JSON.parse(string) # returns a hash

p parsed["desc"]["someKey"]
p parsed["main_item"]["stats"]["a"]

# Read JSON from a file, iterate over objects
file = open("shops.json")
json = file.read

parsed = JSON.parse(json)

parsed["shop"].each do |shop|
  p shop["id"]
end

You don't have to add a . in getElementsByClassName, i.e.

var multibutton = angular.element(element.getElementsByClassName("multi-files"));

However, when using angular.element, you do have to use jquery style selectors:

angular.element('.multi-files');

should do the trick.

Also, from this documentation "If jQuery is available, angular.element is an alias for the jQuery function. If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.""

For the last 3+ years these are the functions that I am using for finding last row and last column per defined column(for row) and row(for column):

Last Column:

Function lastCol(Optional wsName As String, Optional rowToCheck As Long = 1) As Long

    Dim ws  As Worksheet

    If wsName = vbNullString Then
        Set ws = ActiveSheet
    Else
        Set ws = Worksheets(wsName)
    End If

    lastCol = ws.Cells(rowToCheck, ws.Columns.Count).End(xlToLeft).Column

End Function

Last Row:

Function lastRow(Optional wsName As String, Optional columnToCheck As Long = 1) As Long

    Dim ws As Worksheet

    If wsName = vbNullString Then
        Set ws = ActiveSheet
    Else
        Set ws = Worksheets(wsName)
    End If

    lastRow = ws.Cells(ws.Rows.Count, columnToCheck).End(xlUp).Row

End Function

For the case of the OP, this is the way to get the last row in column E:

Debug.Print lastRow(columnToCheck:=Range("E4:E48").Column)

Last Row, counting empty rows with data:

Here we may use the well-known Excel formulas, which give us the last row of a worksheet in Excel, without involving VBA - =IFERROR(LOOKUP(2,1/(NOT(ISBLANK(A:A))),ROW(A:A)),0)

In order to put this in VBA and not to write anything in Excel, using the parameters for the latter functions, something like this could be in mind:

Public Function LastRowWithHidden(Optional wsName As String, Optional columnToCheck As Long = 1) As Long

    Dim ws As Worksheet

    If wsName = vbNullString Then
        Set ws = ActiveSheet
    Else
        Set ws = Worksheets(wsName)
    End If

    Dim letters As String
    letters = ColLettersGenerator(columnToCheck)
    LastRowWithHidden = ws.Evaluate("=IFERROR(LOOKUP(2,1/(NOT(ISBLANK(" & letters & "))),ROW(" & letters & " )),0)")

End Function

Function ColLettersGenerator(col As Long) As String

    Dim result As Variant
    result = Split(Cells(1, col).Address(True, False), "$")
    ColLettersGenerator = result(0) & ":" & result(0)

End Function

You might get better results if you try:

console.log(JSON.stringify(functor));

Try: 

SELECT EXTRACT(EPOCH FROM (timestamp_B - timestamp_A))
FROM TableA

This blog post is a great little cheat-sheet to keep handy when trying to format strings to a variety of formats.

link to trojan removed

Edit

The link was removed because Google temporarily warned that the site (or related site) may have been spreading malicious software. It is now off the list an no longer reported as problematic. Google "SteveX String Formatting" you'll find the search result and you can visit it at your discretion.

Navbars can utilize .navbar-toggler, .navbar-collapse, and .navbar-expand{-sm|-md|-lg|-xl} classes to change when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.

For example :

<nav class="navbar navbar-expand-lg"></nav>

Mobile menu is showing in large screen.

Reference : https://getbootstrap.com/docs/4.0/components/navbar/

You can use the following workaround for it to work with the first parameter too:

var param1 =
    HttpUtility.ParseQueryString(url.Substring(
        new []{0, url.IndexOf('?')}.Max()
    )).Get("param1");

Your browser hasn't interpretted the encoding of the page correctly (either because you've forced it to a particular setting, or the page is set incorrectly), and thus cannot display some of the characters.

You may need to write a javascript for each button submit. Instead of defining action in form definition, set those values in javascript. Something like below.

function callButton1(form, yourServ)
{
form.action = yourServ;
form.submit();
});

System.Windows.Forms.Application.Exit() - Informs all message pumps that they must terminate, and then closes all application windows after the messages have been processed. This method stops all running message loops on all threads and closes all windows of the application. This method does not force the application to exit. The Exit() method is typically called from within a message loop, and forces Run() to return. To exit a message loop for the current thread only, call ExitThread(). This is the call to use if you are running a Windows Forms application. As a general guideline, use this call if you have called System.Windows.Forms.Application.Run().

System.Environment.Exit(exitCode) - Terminates this process and gives the underlying operating system the specified exit code. This call requires that you have SecurityPermissionFlag.UnmanagedCode permissions. If you do not, a SecurityException error occurs. This is the call to use if you are running a console application.

I hope it is best to use Application.Exit

• Application.Exit() vs Application.ExitThread() vs Environment.Exit()

For a more graceful way, try the following:

Caveat: I'm running Debian 7, not Ubuntu, though it is a Debian derivative

If you're running Tomcat as a service, you can get a list of all running services by typing:

sudo service --status-all

I'm running Tomcat 7, which is displayed as tomcat7 in said list. Then, to shut it down just type:

sudo service tomcat7 stop

You could also take a look at a past sample project of mine, written for this purpose. I saves locally a name and retrieves it either upon a user's request or when the app starts.

But, at this time, it would be better to use commit (instead of apply) for persisting the data. More info here.

integrity - defines the hash value of a resource (like a checksum) that has to be matched to make the browser execute it. The hash ensures that the file was unmodified and contains expected data. This way browser will not load different (e.g. malicious) resources. Imagine a situation in which your JavaScript files were hacked on the CDN, and there was no way of knowing it. The integrity attribute prevents loading content that does not match.

Invalid SRI will be blocked (Chrome developer-tools), regardless of cross-origin. Below NON-CORS case when integrity attribute does not match:

Integrity can be calculated using: https://www.srihash.org/ Or typing into console (link):

openssl dgst -sha384 -binary FILENAME.js | openssl base64 -A

crossorigin - defines options used when the resource is loaded from a server on a different origin. (See CORS (Cross-Origin Resource Sharing) here: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS). It effectively changes HTTP requests sent by the browser. If the “crossorigin” attribute is added - it will result in adding origin: <ORIGIN> key-value pair into HTTP request as shown below.

crossorigin can be set to either “anonymous” or “use-credentials”. Both will result in adding origin: into the request. The latter however will ensure that credentials are checked. No crossorigin attribute in the tag will result in sending a request without origin: key-value pair.

Here is a case when requesting “use-credentials” from CDN:

<script 
        src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js"
        integrity="sha384-vBWWzlZJ8ea9aCX4pEW3rVHjgjt7zpkNpZk+02D9phzyeVkE+jo0ieGizqPLForn" 
        crossorigin="use-credentials"></script>

A browser can cancel the request if crossorigin incorrectly set.

I also found this problem. What do did to solve this is to copy/paste this file everywhere and run, one file a time. Finally it compiled and ran successfully, and then delete the unnecessary ones. The correct place in my situation is:

This is under the /src/ path (I am using Intellij Idea as the IDE). The other java source files are under /src/com/package/ path

Hope it helpes.

If you're using WinJS you can change the src through the Utilities functions.

WinJS.Utilities.id("pic1").setAttribute("src", searchPic.src);

The homebrew package for node.js now includes npm again, so this happened to me when I missed the homebrew package's message about removing the standalone version first.

Assuming, like me, you've already broken node/npm by attempting the upgrade before knowing to npm uninstall npm -g first, you can rm -rf /usr/local/lib/node_modules/npm and then brew link node. This removes the standalone self-hosted npm package (rather than the one brew would like to install) and lets brew symlink its bundled one from Cellar.

This seems a very old question, but I am providing an answer, so that it might help others. You can specify the variables in the second screen in the form section, as shown below or in the RAW format by appending the variables as shown in the second image.

If your variable and variable values are valid, you should see a successful response in the response section.

Recently I was also having this issue, then I contacted Google Support and they gave me this link to provide required info, I posted and within 24 hours my problem was fixed.

It means if the screen size is 1024 then only apply below CSS rules.

Also remember that you can pass a second argument to the .forEach() function specifying the object to use as the this keyword.

// myOjbect is the object you want to iterate.
// Notice the second argument (secondArg) we passed to .forEach.
Object.keys(myObject).forEach(function(element, key, _array) {
  // element is the name of the key.
  // key is just a numerical value for the array
  // _array is the array of all the keys

  // this keyword = secondArg
  this.foo;
  this.bar();
}, secondArg);

jsonify prevents you from doing this in Flask 0.10 and lower for security reasons.

To do it anyway, just use json.dumps in the Python standard library.

http://docs.python.org/library/json.html#json.dumps

Think of "BeforeClass" as a static initializer for your test case - use it for initializing static data - things that do not change across your test cases. You definitely want to be careful about static resources that are not thread safe.

Finally, use the "AfterClass" annotated method to clean up any setup you did in the "BeforeClass" annotated method (unless their self destruction is good enough).

"Before" & "After" are for unit test specific initialization. I typically use these methods to initialize / re-initialize the mocks of my dependencies. Obviously, this initialization is not specific to a unit test, but general to all unit tests.

Use your browser's network inspector (F12) to see when the browser is requesting the bgbody.png image and what absolute path it's using and why the server is returning a 404 response.

...assuming that bgbody.png actually exists :)

Is your CSS in a stylesheet file or in a <style> block in a page? If it's in a stylesheet then the relative path must be relative to the CSS stylesheet (not the document that references it). If it's in a page then it must be relative to the current resource path. If you're using non-filesystem-based resource paths (i.e. using URL rewriting or URL routing) then this will cause problems and it's best to always use absolute paths.

Going by your relative path it looks like you store your images separately from your stylesheets. I don't think this is a good idea - I support storing images and other resources, like fonts, in the same directory as the stylesheet itself, as it simplifies paths and is also a more logical filesystem arrangement.

Pull with rebase

A regular pull is fetch + merge, but what you want is fetch + rebase. This is an option with the pull command:

git pull --rebase

To get the selected value of a spinner you can follow this example.

Create a nested class that implements AdapterView.OnItemSelectedListener. This will provide a callback method that will notify your application when an item has been selected from the Spinner.

Within "onItemSelected" method of that class, you can get the selected item:

public class YourItemSelectedListener implements OnItemSelectedListener {

    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        String selected = parent.getItemAtPosition(pos).toString();
    }

    public void onNothingSelected(AdapterView parent) {
        // Do nothing.
    }
}

Finally, your ItemSelectedListener needs to be registered in the Spinner:

spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

it's pretty painless to pop a couple methods in a file that will handle asynchronous data in a serialized order and give a more conventional flavour to your code. For example:

module.exports = function () {
  var self = this;

  this.each = async (items, fn) => {
    if (items && items.length) {
      await Promise.all(
        items.map(async (item) => {
          await fn(item);
        }));
    }
  };

  this.reduce = async (items, fn, initialValue) => {
    await self.each(
      items, async (item) => {
        initialValue = await fn(initialValue, item);
      });
    return initialValue;
  };
};

now, assuming that's saved at './myAsync.js' you can do something similar to the below in an adjacent file:

...
/* your server setup here */
...
var MyAsync = require('./myAsync');
var Cat = require('./models/Cat');
var Doje = require('./models/Doje');
var example = async () => {
  var myAsync = new MyAsync();
  var doje = await Doje.findOne({ name: 'Doje', noises: [] }).save();
  var cleanParams = [];

  // FOR EACH EXAMPLE
  await myAsync.each(['bork', 'concern', 'heck'], 
    async (elem) => {
      if (elem !== 'heck') {
        await doje.update({ $push: { 'noises': elem }});
      }
    });

  var cat = await Cat.findOne({ name: 'Nyan' });

  // REDUCE EXAMPLE
  var friendsOfNyanCat = await myAsync.reduce(cat.friends,
    async (catArray, friendId) => {
      var friend = await Friend.findById(friendId);
      if (friend.name !== 'Long cat') {
        catArray.push(friend.name);
      }
    }, []);
  // Assuming Long Cat was a friend of Nyan Cat...
  assert(friendsOfNyanCat.length === (cat.friends.length - 1));
}

To compare up to a given decimal without atol/rtol:

def almost_equal(a, b, decimal=6):
    return '{0:.{1}f}'.format(a, decimal) == '{0:.{1}f}'.format(b, decimal)

print(almost_equal(0.0, 0.0001, decimal=5)) # False
print(almost_equal(0.0, 0.0001, decimal=4)) # True 

Actually "Sheet1" object / code name can be changed. In VBA, click on Sheet1 in Excel Objects list. In the properties window, you can change Sheet1 to say rng.

Then you can reference rng as a global object without having to create a variable first. So debug.print rng.name works just fine. No more Worksheets("rng").name.

Unlike the tab, the object name has same restrictions as other variables (i.e. no spaces).

If you are looking for a particular type of element that is further away than the immediate parent, you can use a function that goes up the DOM until it finds one, or doesn't:

// Find first ancestor of el with tagName
// or undefined if not found
function upTo(el, tagName) {
  tagName = tagName.toLowerCase();

  while (el && el.parentNode) {
    el = el.parentNode;
    if (el.tagName && el.tagName.toLowerCase() == tagName) {
      return el;
    }
  }

  // Many DOM methods return null if they don't 
  // find the element they are searching for
  // It would be OK to omit the following and just
  // return undefined
  return null;
}

I encountered a similar problem but a complex one and since this is the first thread i found regarding that issue i decided to post my finding. i know it is complex solution to a simple problem but i hope that i could help other people who go to this thread looking for a more complex solution. i had to split a string containing 5 numbers (column name: levelsFeed) and to show each number in a separate column. for example: 8,1,2,2,2 should be shown as :

1  2  3  4  5
-------------
8  1  2  2  2

Solution 1: using XML functions: this solution for the slowest solution by far

SELECT Distinct FeedbackID, 
, S.a.value('(/H/r)[1]', 'INT') AS level1
, S.a.value('(/H/r)[2]', 'INT') AS level2
, S.a.value('(/H/r)[3]', 'INT') AS level3
, S.a.value('(/H/r)[4]', 'INT') AS level4
, S.a.value('(/H/r)[5]', 'INT') AS level5
FROM (            
    SELECT *,CAST (N'<H><r>' + REPLACE(levelsFeed, ',', '</r><r>')  + '</r> </H>' AS XML) AS [vals]
    FROM Feedbacks 
)  as d
CROSS APPLY d.[vals].nodes('/H/r') S(a)

Solution 2: using Split function and pivot. (the split function split a string to rows with the column name Data)

SELECT FeedbackID, [1],[2],[3],[4],[5]
FROM (
    SELECT *, ROW_NUMBER() OVER (PARTITION BY feedbackID ORDER BY (SELECT  null)) as rn 
FROM (
    SELECT FeedbackID, levelsFeed
    FROM Feedbacks 
) as a
CROSS APPLY dbo.Split(levelsFeed, ',')
) as SourceTable
PIVOT
(
    MAX(data)
    FOR rn IN ([1],[2],[3],[4],[5])
)as pivotTable

Solution 3: using string manipulations functions - fastest by small margin over solution 2

SELECT FeedbackID,
SUBSTRING(levelsFeed,0,CHARINDEX(',',levelsFeed)) AS level1,
PARSENAME(REPLACE(SUBSTRING(levelsFeed,CHARINDEX(',',levelsFeed)+1,LEN(levelsFeed)),',','.'),4) AS level2,
PARSENAME(REPLACE(SUBSTRING(levelsFeed,CHARINDEX(',',levelsFeed)+1,LEN(levelsFeed)),',','.'),3) AS level3,
PARSENAME(REPLACE(SUBSTRING(levelsFeed,CHARINDEX(',',levelsFeed)+1,LEN(levelsFeed)),',','.'),2) AS level4,
PARSENAME(REPLACE(SUBSTRING(levelsFeed,CHARINDEX(',',levelsFeed)+1,LEN(levelsFeed)),',','.'),1) AS level5
FROM Feedbacks

since the levelsFeed contains 5 string values i needed to use the substring function for the first string.

i hope that my solution will help other that got to this thread looking for a more complex split to columns methods

TableExport - The simple, easy-to-implement library to export HTML tables to xlsx, xls, csv, and txt files.

To use this library, simple call the TableExport constructor:

new TableExport(document.getElementsByTagName("table"));

// OR simply

TableExport(document.getElementsByTagName("table"));

// OR using jQuery

$("table").tableExport(); 

Additional properties can be passed-in to customize the look and feel of your tables, buttons, and exported data. See here more info

An additional consideraion that I have not seen in the answers already given, is that included columns can be of data types that are not allowed as index key columns, such as varchar(max).

This allows you to include such columns in a covering index. I recently had to do this to provide a nHibernate generated query, which had a lot of columns in the SELECT, with a useful index.

And if you want to search and replace based on the value of another field you could do a CONCAT:

update table_name set `field_name` = replace(`field_name`,'YOUR_OLD_STRING',CONCAT('NEW_STRING',`OTHER_FIELD_VALUE`,'AFTER_IF_NEEDED'));

Just to have this one here so that others will find it at once.

For a side note, I personally use [Foo new] if I want something in init to be done without using it's return value anywhere. If you do not use the return of [[Foo alloc] init] anywhere then you will get a warning. More or less, I use [Foo new] for eye candy.

Another way using regular expressions

int length = text.replaceAll("[^ ]", "").length();

If you've accidentally or not mixed integers with text data you should at first execute below update command (if not above alter table will fail):

UPDATE the_table SET col_name = replace(col_name, 'some_string', '');

And there might be some methods doing that in Excel.

I had a similar issue with the iteration and I landed here. Maybe someone else is also doing the same mistake I did.

In my case, the selector was not the problem at all. The problem was that I had messed up the javascript code: I had a loop and a subloop. The subloop was also using i as a counter, instead of j, so because the subloop was overriding the value of i of the main loop, this one never got to the second iteration.

var dayContainers = document.getElementsByClassName('day-container');
for(var i = 0; i < dayContainers.length; i++) { //loop of length = 2
        var thisDayDiv = dayContainers[i];
        // do whatever

        var inputs = thisDayDiv.getElementsByTagName('input');

        for(var j = 0; j < inputs.length; j++) { //loop of length = 4
            var thisInput = inputs[j];
            // do whatever

        };

    };

Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

To use shorthand to get the direction:

int direction = column == 0
                ? 0
                : (column == _gridSize - 1 ? 1 : rand.Next(2));

To simplify the code entirely:

if (column == gridSize - 1 || rand.Next(2) == 1)
{
}
else
{
}

I did it with jQuery:

If you rename your getAvailability() method to getAvailableAttribute() your method becomes an accessor and you'll be able to read it using ->available straight on your model.

Docs: https://laravel.com/docs/5.4/eloquent-mutators#accessors-and-mutators

EDIT: Since your attribute is "virtual", it is not included by default in the JSON representation of your object.

But I found this: Custom model accessors not processed when ->toJson() called?

In order to force your attribute to be returned in the array, add it as a key to the $attributes array.

class User extends Eloquent {
    protected $attributes = array(
        'ZipCode' => '',
    );

    public function getZipCodeAttribute()
    {
        return ....
    }
}

I didn't test it, but should be pretty trivial for you to try in your current setup.

The reason is that modprobe looks into /lib/modules/$(uname -r) for the modules and therefore won't work with local file path. That's one of differences between modprobe and insmod.

For short queries that can fit on one or two lines, I use the string literal solution in the top-voted solution above. For longer queries, I break them out to .sql files. I then use a wrapper function to load the file and execute the script, something like:

script_cache = {}
def execute_script(cursor,script,*args,**kwargs):
    if not script in script_cache:
        with open(script,'r') as s:
            script_cache[script] = s
    return cursor.execute(script_cache[script],*args,**kwargs)

Of course this often lives inside a class so I don't usually have to pass cursor explicitly. I also generally use codecs.open(), but this gets the general idea across. Then SQL scripts are completely self-contained in their own files with their own syntax highlighting.

According to John Day's answer

You should have a Data/Packages folder in your Sublime Text 2 install directory. All you need to do is download the plugin and put the plugin folder in the Packages folder.

In case if you are searching for Data/Packages folder you can find it here

Windows: %APPDATA%\Sublime Text 2

OS X: ~/Library/Application Support/Sublime Text 2

Linux: ~/.Sublime Text 2

You can set sys.dont_write_bytecode = True in your source, but that would have to be in the first python file loaded. If you execute python somefile.py then you will not get somefile.pyc.

When you install a utility using setup.py and entry_points= you will have set sys.dont_write_bytecode in the startup script. So you cannot rely on the "default" startup script generated by setuptools.

If you start Python with python file as argument yourself you can specify -B:

python -B somefile.py

somefile.pyc would not be generated anyway, but no .pyc files for other files imported too.

If you have some utility myutil and you cannot change that, it will not pass -B to the python interpreter. Just start it by setting the environment variable PYTHONDONTWRITEBYTECODE:

PYTHONDONTWRITEBYTECODE=x myutil

You can use gravity with aligning top and bottom.

Specifies that a following d , i , o , u , x , X , or n conversion specifier applies to an argument with type pointer to short or unsigned short.

Well the easy answer would be: "your executable files are in the directories contained in your PATH variable" but that would not really find your executables and could miss a lot of executables anyway.

I don't know much about mac but I think "mdfind 'kMDItemContentType=public.unix-executable'" might miss stuff like interpreted scripts

If it's ok for you to find files with the executable bits set (regardless of whether they are actually executable) then it's fine to do

find . -type f -perm +111 -print

where supported the "-executable" option will make a further filter looking at acl and other permission artifacts but is technically not much different to "-pemr +111".

Maybe in the future find will support "-magic " and let you look explicitly for files with a specific magic id ... but then you would haveto specify to fine all the executable formats magic id.

I'm unaware of a technically correct easy way out on unix.

following code works just fine for me.

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(movieurl));
startActivity(intent);

For Mac:

Click on the first cell having the formula and press Ctrl + Shift + down_arrow. This will select the last cell in the column used on the worksheet.

command + D. (don't use ctrl) This will fill the formula in the remaining cells.

Checking Count() before the WHERE clause solved my problem. It is cheaper than ToList()

if (authUserList != null && _list.Count() > 0)
    _list = _list.Where(l => authUserList.Contains(l.CreateUserId));

MSDN seems to have an article for this now:

Intro:

By default, Windows Communication Foundation (WCF) makes endpoints available only to SOAP clients. In How to: Create a Basic WCF Web HTTP Service, an endpoint is made available to non-SOAP clients. There may be times when you want to make the same contract available both ways, as a Web endpoint and as a SOAP endpoint. This topic shows an example of how to do this.

As already stated, unique requires a sorted container. Additionally, unique doesn't actually remove elements from the container. Instead, they are copied to the end, unique returns an iterator pointing to the first such duplicate element, and you are expected to call erase to actually remove the elements.

.sort(), in pymongo, takes key and direction as parameters.

So if you want to sort by, let's say, id then you should .sort("_id", 1)

For multiple fields:

.sort([("field1", pymongo.ASCENDING), ("field2", pymongo.DESCENDING)])

You need to call .validate() before you can add rules this way, like this:

$("#myForm").validate(); //sets up the validator
$("input[id*=Hours]").rules("add", "required");

The .validate() documentation is a good guide, here's the blurb about .rules("add", option):

Adds the specified rules and returns all rules for the first matched element. Requires that the parent form is validated, that is, $("form").validate() is called first.

I don't know why but for me the solution proposed by Marius Stanescu is breaking the specificity of col (a col-md-3 followed by a col-md-4 will take all of the twelve row)

I found another working solution :

.bottom-column 
{
   display: inline-block;
   vertical-align: middle;
   float: none;
}

I do not know much about Java but URL query arguments should be separated by "&", not "?"

http://tools.ietf.org/html/rfc3986 is good place for reference using "sub-delim" as keyword. http://en.wikipedia.org/wiki/Query_string is another good source.

With some little changes to hobodave's code, here is a codesnippet you can use to crawl pages. This needs the curl extension to be enabled in your server.

<?php
//set_time_limit (0);
function crawl_page($url, $depth = 5){
$seen = array();
if(($depth == 0) or (in_array($url, $seen))){
    return;
}   
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$result = curl_exec ($ch);
curl_close ($ch);
if( $result ){
    $stripped_file = strip_tags($result, "<a>");
    preg_match_all("/<a[\s]+[^>]*?href[\s]?=[\s\"\']+"."(.*?)[\"\']+.*?>"."([^<]+|.*?)?<\/a>/", $stripped_file, $matches, PREG_SET_ORDER ); 
    foreach($matches as $match){
        $href = $match[1];
            if (0 !== strpos($href, 'http')) {
                $path = '/' . ltrim($href, '/');
                if (extension_loaded('http')) {
                    $href = http_build_url($href , array('path' => $path));
                } else {
                    $parts = parse_url($href);
                    $href = $parts['scheme'] . '://';
                    if (isset($parts['user']) && isset($parts['pass'])) {
                        $href .= $parts['user'] . ':' . $parts['pass'] . '@';
                    }
                    $href .= $parts['host'];
                    if (isset($parts['port'])) {
                        $href .= ':' . $parts['port'];
                    }
                    $href .= $path;
                }
            }
            crawl_page($href, $depth - 1);
        }
}   
echo "Crawled {$href}";
}   
crawl_page("http://www.sitename.com/",3);
?>

I have explained this tutorial in this crawler script tutorial

Simple answer is NO !!.

There is no FOR in SQL, But you can use WHILE or GOTO to achieve the way how the FOR will work.

WHILE :

DECLARE @a INT = 10

WHILE @a <= 20
BEGIN
    PRINT @a
    SET @a = @a + 1
END

GOTO :

DECLARE @a INT = 10
a:
PRINT @a
SET @a = @a + 1
IF @a < = 20
BEGIN
    GOTO a
END

I always prefer WHILE over GOTO statement.

I was needing to print DEBUG info in some logs and was unable to use pprint because it would break it. Instead I did this and got virtually the same thing.

DO = DemoObject()

itemDir = DO.__dict__

for i in itemDir:
    print '{0}  :  {1}'.format(i, itemDir[i])

You can use the jQuery prop() method to disable or enable form element or control dynamically using jQuery. The prop() method require jQuery 1.6 and above.

Example:

<script type="text/javascript">
        $(document).ready(function(){
            $('form input[type="submit"]').prop("disabled", true);
            $(".agree").click(function(){
                if($(this).prop("checked") == true){
                    $('form input[type="submit"]').prop("disabled", false);
                }
                else if($(this).prop("checked") == false){
                    $('form input[type="submit"]').prop("disabled", true);
                }
            });
        });
    </script>

var pixelFromTop = 500;     
$('html, body').animate({ scrollTop: pixelFromTop  }, 1);

So when page open it is automatically scroll down after 1 milisecond

break breaks out of a loop, not an if statement, as others have pointed out. The motivation for this isn't too hard to see; think about code like

for item in some_iterable:
    ...
    if break_condition():
        break 

The break would be pretty useless if it terminated the if block rather than terminated the loop -- terminating a loop conditionally is the exact thing break is used for.

Before Java 7:

 BufferedReader br = new BufferedReader(new FileReader("foo.txt"));
 String line;
 while ((line = br.readLine()) != null) {
   System.out.println(line);
 }

• add exception handling
• add closing the stream

Since Java 7, there is no need to close the stream, because it implements autocloseable

try (BufferedReader br = new BufferedReader(new FileReader("foo.txt"))) {
   String line;
   while ((line = br.readLine()) != null) {
       System.out.println(line);
   }
}

You can do it directly from eclipse using the Navigator view (Window -> Show View -> Navigator). In the Navigator view select the project and open it so that you can see the file .project. Right click -> Open. You will get a XML editor view. Edit the content of the node natures and insert a new child nature with org.eclipse.jdt.core.javanature as content. Save.

Now create a file .classpath, it will open in the XML editor. Add a node named classpath, add a child named classpathentry with the attributes kind with content con and another one named path and content org.eclipse.jdt.launching.JRE_CONTAINER. Save-

Much easier: copy the files .project and .classpath from an existing Java project and edit the node result name to the name of this project. Maybe you have to refresh the project (F5).

You'll get the same result as with the solution of Chris Marasti-Georg.

Edit

Assuming that you know that the root elements are zero, here's the pseudocode to output to text:

function PrintLevel (int curr, int level)
    //print the indents
    for (i=1; i<=level; i++)
        print a tab
    print curr \n;
    for each child in the table with a parent of curr
        PrintLevel (child, level+1)


for each elementID where the parentid is zero
    PrintLevel(elementID, 0)

Just add a background image to all images using css:

img {
  background: url('loading.gif') no-repeat;
}

Is there a better way? yes. Do not use MySQL Timestamps. Apart from the fact that they occupy 36 Bytes, they are not at all convenient to work with. I would reccomend using Julian Date and Seconds from midnight for all date/time values. These can be combined to form a UnixDateTime. If this is stored in a DWORD (unsigned 4 Byte Integer) then dates all the way up to 2106 can be stored as seconds since epoc, 01/01/1970 DWORD max val = 4,294,967,295 - A DWORD can hold 136 years of Seconds

Julian Dates are very nice to work with when making date calculations UNIXDateTime values are good to work with when making Date/Time calculations Neither are good to look at, so I use the Timestamps when I need a column that I will not be doing much calculation with, but I want an at-a-glance indication.

Converting to Julian and back can be done very quickly in a good language. Using pointers I have it down to about 900 Clks (This is also a conversion from a STRING to an INTEGER of course)

When you get into serious applications that use Date/Time information like for example the financial markets, Julian dates are de-facto.

Is the value of your particular COMMENT column null?

Sometimes NOT LIKE doesn't know how to behave properly around nulls.

You can modify the whole InfoWindow using jquery alone...

var popup = new google.maps.InfoWindow({
    content:'<p id="hook">Hello World!</p>'
});

Here the <p> element will act as a hook into the actual InfoWindow. Once the domready fires, the element will become active and accessible using javascript/jquery, like $('#hook').parent().parent().parent().parent().

The below code just sets a 2 pixel border around the InfoWindow.

google.maps.event.addListener(popup, 'domready', function() {
    var l = $('#hook').parent().parent().parent().siblings();
    for (var i = 0; i < l.length; i++) {
        if($(l[i]).css('z-index') == 'auto') {
            $(l[i]).css('border-radius', '16px 16px 16px 16px');
            $(l[i]).css('border', '2px solid red');
        }
    }
});

You can do anything like setting a new CSS class or just adding a new element.

Play around with the elements to get what you need...

A better way to add the multiple classes separated by spaces in a string is using the Spread_syntax with the split:

element.classList.add(...classesStr.split(" "));

You can use React-Bootstrap (https://react-bootstrap.github.io/components/modal). There is an example for modals at that link. Once you have loaded react-bootstrap, the modal component can be used as a react component:

var Modal = ReactBootstrap.Modal;

can then be used as a react component as <Modal/>.

For Bootstrap 4, there is react-strap (https://reactstrap.github.io). React-Bootstrap only supports Bootstrap 3.

You have empty $_POST. If your web-server wants see data in json-format you need to read the raw input and then parse it with JSON decode.

You need something like that:

$json = file_get_contents('php://input');
$obj = json_decode($json);

Also you have wrong code for testing JSON-communication...

CURLOPT_POSTFIELDS tells curl to encode your parameters as application/x-www-form-urlencoded. You need JSON-string here.

UPDATE

Your php code for test page should be like that:

$data_string = json_encode($data);

$ch = curl_init('http://webservice.local/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);
$result = json_decode($result);
var_dump($result);

Also on your web-service page you should remove one of the lines header('Content-type: application/json');. It must be called only once.

try this,

package example.txtRead;

    int j=0;
    private StringTokenizer tokenizer;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        wordss = new Vector<String>();
        TextView helloTxt = (TextView)findViewById(R.id.hellotxt);
        helloTxt.setText(readTxt());
 }

    private String readTxt(){

     InputStream inputStream = getResources().openRawResource(R.raw.toc);
//     InputStream inputStream = getResources().openRawResource(R.raw.internals);
     System.out.println(inputStream);
     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

     int i;
  try {
   i = inputStream.read();
   while (i != -1)
      {
       byteArrayOutputStream.write(i);
       i = inputStream.read();
      }
      inputStream.close();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

     return byteArrayOutputStream.toString();
    }
}

The jQuery find() is returning a jQuery object that wraps the DOM object. You should be able to work with that object to do what you'd like with the div.

string userRequest = System.Web.HttpContext.Current.Request.UserHostAddress;

This works on me.

System.Web.HttpContext.Current.Request.UserHostName; this one return me the same return I get from the UserHostAddress.

Basically you shouldn't do exact comparisons, you should do something like this:

double a = 1.000001;
double b = 0.000001;
double c = a-b;
if (Math.abs(c-1.0) <= 0.000001) {...}

In HTML5, to select a disabled option:

<option selected disabled>Choose Tagging</option>

if you found out that the memory settings were not being used and in order to change the memory settings, I used the tomcat7w or tomcat8w in the \bin folder.Then the following should pop up:

Click the Java tab and add the arguments.restart tomcat

I know it is been answered long time ago, but i would like to share this also:

This code works very well:

SQLiteDatabase db = this.getReadableDatabase();
long taskCount = DatabaseUtils.queryNumEntries(db, TABLE_TODOTASK);

BUT what if i dont want to count all rows and i have a condition to apply?

DatabaseUtils have another function for this: DatabaseUtils.longForQuery

long taskCount = DatabaseUtils.longForQuery(db, "SELECT COUNT (*) FROM " + TABLE_TODOTASK + " WHERE " + KEY_TASK_TASKLISTID + "=?",
         new String[] { String.valueOf(tasklist_Id) });

The longForQuery documentation says:

Utility method to run the query on the db and return the value in the first column of the first row.

public static long longForQuery(SQLiteDatabase db, String query, String[] selectionArgs)

It is performance friendly and save you some time and boilerplate code

Hope this will help somebody someday :)

My solution below is in es6 because I made use of const if you prefer es5 you can replace all const with var.

const str = "       Hello World!        ";_x000D_

_x000D_
checkForWhiteSpaces(str);_x000D_
_x000D_
function checkForWhiteSpaces(args) {_x000D_
    const trimmedString = args.trim().length;_x000D_
    console.log(checkStringLength(trimmedString))     _x000D_
    return checkStringLength(trimmedString)        _x000D_
}_x000D_
_x000D_
// If the browser doesn't support the trim function_x000D_
// you can make use of the regular expression below_x000D_
_x000D_
checkForWhiteSpaces2(str);_x000D_
_x000D_
function checkForWhiteSpaces2(args) {_x000D_
    const trimmedString = args.replace(/^\s+|\s+$/gm, '').length;_x000D_

Looks like you're a little bit confused about all that stuff.

operator is a built-in module providing a set of convenient operators. In two words operator.itemgetter(n) constructs a callable that assumes an iterable object (e.g. list, tuple, set) as input, and fetches the n-th element out of it.

So, you can't use key=a[x][1] there, because python has no idea what x is. Instead, you could use a lambda function (elem is just a variable name, no magic there):

a.sort(key=lambda elem: elem[1])

Or just an ordinary function:

def get_second_elem(iterable):
    return iterable[1]

a.sort(key=get_second_elem)

So, here's an important note: in python functions are first-class citizens, so you can pass them to other functions as a parameter.

Other questions:

1. Yes, you can reverse sort, just add reverse=True: a.sort(key=..., reverse=True)
2. To sort by more than one column you can use itemgetter with multiple indices: operator.itemgetter(1,2), or with lambda: lambda elem: (elem[1], elem[2]). This way, iterables are constructed on the fly for each item in list, which are than compared against each other in lexicographic(?) order (first elements compared, if equal - second elements compared, etc)
3. You can fetch value at [3,2] using a[2,1] (indices are zero-based). Using operator... It's possible, but not as clean as just indexing.

Refer to the documentation for details:

1. operator.itemgetter explained
2. Sorting list by custom key in Python

There's a tidier way to include variables inside the escaped calc, as explained in this post: CSS3 calc() function doesn't work with Less #974

@variable: 2em;

body{ width: calc(~"100% - @{variable} * 2");}

By using the curly brackets you don't need to close and reopen the escaping quotes.

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
        // This would also prevent them from using the "forward" button to return to the new hash.
        window.history.replaceState(
            { isBackPage: false },
            "<new name>",
            "<new url>"
        );
    } else {
        if (e.state.isBackPage) {
            // If there is state and it's the 'back' page...

            if (myHistory.length > 0) {
                // Pull/load the page from our custom history...
                var pg = myHistory.pop();
                // <load/render/whatever>

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)
    }
}

To answer your bonus question, the general answer is no, you don't need to set variables to "Nothing" in short .VBS scripts like yours, that get called by Wscript or Cscript.

The reason you might do this in the middle of a longer script is to release memory back to the operating system that VB would otherwise have been holding. These days when 8GB of RAM is typical and 16GB+ relatively common, this is unlikely to produce any measurable impact, even on a huge script that has several megabytes in a single variable. At this point it's kind of a hold-over from the days where you might have been working in 1MB or 2MB of RAM.

You're correct, the moment your .VBS script completes, all of your variables get destroyed and the memory is reclaimed anyway. Setting variables to "Nothing" simply speeds up that process, and allows you to do it in the middle of a script.

You can do that simple with Files.size(new File(filename).toPath()).

You can do:

$("#country.save")...

OR

$("a#country.save")...

OR

$("a.save#country")...

as you prefer.

So yes you can specify a selector that has to match ID and class (and potentially tag name and anything else you want to throw in).

• Lets say 1st component is DbstatsMainComponent
• 2nd component DbstatsGraphComponent.
• 1st component calling the method of 2nd

<button (click)="dbgraph.displayTableGraph()">Graph</button> <dbstats-graph #dbgraph></dbstats-graph>

Note the local variable #dbgraph on the child component, which the parent can use to access its methods (dbgraph.displayTableGraph()).

The account that sql server is running under does not have access to the location where you have the backup file or are trying to restore the database to. You can use SQL Server Configuration Manager to find which account is used to run the SQL Server instance, and then make sure that account has full control over the .BAK file and the folder where the MDF will be restored to.

The %c conversion specifier won't automatically skip any leading whitespace, so if there's a stray newline in the input stream (from a previous entry, for example) the scanf call will consume it immediately.

One way around the problem is to put a blank space before the conversion specifier in the format string:

scanf(" %c", &c);

The blank in the format string tells scanf to skip leading whitespace, and the first non-whitespace character will be read with the %c conversion specifier.

sequenceName is the name of the sequence in the DB. This is how you specify a sequence that already exists in the DB. If you go this route, you have to specify the allocationSize which needs to be the same value that the DB sequence uses as its "auto increment".

Usage:

@GeneratedValue(generator="my_seq")
@SequenceGenerator(name="my_seq",sequenceName="MY_SEQ", allocationSize=1)

If you want, you can let it create a sequence for you. But to do this, you must use SchemaGeneration to have it created. To do this, use:

@GeneratedValue(strategy=GenerationType.SEQUENCE)

Also, you can use the auto-generation, which will use a table to generate the IDs. You must also use SchemaGeneration at some point when using this feature, so the generator table can be created. To do this, use:

@GeneratedValue(strategy=GenerationType.AUTO)

I had some problem getting the other examples to work.

EPPlus and other libraries produces OpenDocument Xml format, which is not the same as you get when you save from Excel as xlsx.

macks example with open CSV and just re-saving didn't work, I never managed to get the ',' delimiter to be used correctly.

Ansgar Wiechers example has some slight error which I found the answer for in the commencts.

Anyway, this is a complete working example. Save this in a File CsvToExcel.ps1

param (
[Parameter(Mandatory=$true)][string]$inputfile,
[Parameter(Mandatory=$true)][string]$outputfile
)

$excel = New-Object -ComObject Excel.Application
$excel.Visible = $false

$wb = $excel.Workbooks.Add()
$ws = $wb.Sheets.Item(1)

$ws.Cells.NumberFormat = "@"

write-output "Opening $inputfile"

$i = 1
Import-Csv $inputfile | Foreach-Object { 
    $j = 1
    foreach ($prop in $_.PSObject.Properties)
    {
        if ($i -eq 1) {
            $ws.Cells.Item($i, $j) = $prop.Name
        } else {
            $ws.Cells.Item($i, $j) = $prop.Value
        }
        $j++
    }
    $i++
}

$wb.SaveAs($outputfile,51)
$wb.Close()
$excel.Quit()
write-output "Success"

Execute with:

.\CsvToExcel.ps1 -inputfile "C:\Temp\X\data.csv" -outputfile "C:\Temp\X\data.xlsx"

It may be something like this in HTML:

<div class="container-outer">
   <div class="container-inner">
      <!-- Your images over here -->
   </div>
</div>

With this stylesheet:

.container-outer { overflow: scroll; width: 500px; height: 210px; }
.container-inner { width: 10000px; }

You can even create an intelligent script to calculate the inner container width, like this one:

$(document).ready(function() {
   var container_width = SINGLE_IMAGE_WIDTH * $(".container-inner a").length;
   $(".container-inner").css("width", container_width);
});

$('#some_select_box option:selected').remove();

mysqldump can take a tbl_name parameter, so that it only backups the given tables.

mysqldump -u -p yourdb yourtable > c:\backups\backup.sql

When you say [:-1] you are stripping the last element. Instead of slicing the string, you can apply startswith and endswith on the string object itself like this

if str1.startswith('"') and str1.endswith('"'):

So the whole program becomes like this

>>> str1 = '"xxx"'
>>> if str1.startswith('"') and str1.endswith('"'):
...     print "hi"
>>> else:
...     print "condition fails"
...
hi

Even simpler, with a conditional expression, like this

>>> print("hi" if str1.startswith('"') and str1.endswith('"') else "fails")
hi

you have to open a port of the service in you router then try you puplic ip out of your all network cause if you try it from your network , the puplic ip will always redirect you to your router but from the outside it will redirect to the server you have

You will need to add the jar to your local maven repository. Alternatively (better option) specify the proper repository (if one exists) so it can be automatically downloaded by maven

In either case, remove the <systemPath> tag from the dependency

I was catching GuzzleHttp\Exception\BadResponseException as @dado is suggesting. But one day I got GuzzleHttp\Exception\ConnectException when DNS for domain wasn't available. So my suggestion is - catch GuzzleHttp\Exception\ConnectException to be safe about DNS errors as well.

There is also the C way of doing callbacks: function pointers

//Define a type for the callback signature,
//it is not necessary, but makes life easier

//Function pointer called CallbackType that takes a float
//and returns an int
typedef int (*CallbackType)(float);  


void DoWork(CallbackType callback)
{
  float variable = 0.0f;

  //Do calculations

  //Call the callback with the variable, and retrieve the
  //result
  int result = callback(variable);

  //Do something with the result
}

int SomeCallback(float variable)
{
  int result;

  //Interpret variable

  return result;
}

int main(int argc, char ** argv)
{
  //Pass in SomeCallback to the DoWork
  DoWork(&SomeCallback);
}

Now if you want to pass in class methods as callbacks, the declarations to those function pointers have more complex declarations, example:

//Declaration:
typedef int (ClassName::*CallbackType)(float);

//This method performs work using an object instance
void DoWorkObject(CallbackType callback)
{
  //Class instance to invoke it through
  ClassName objectInstance;

  //Invocation
  int result = (objectInstance.*callback)(1.0f);
}

//This method performs work using an object pointer
void DoWorkPointer(CallbackType callback)
{
  //Class pointer to invoke it through
  ClassName * pointerInstance;

  //Invocation
  int result = (pointerInstance->*callback)(1.0f);
}

int main(int argc, char ** argv)
{
  //Pass in SomeCallback to the DoWork
  DoWorkObject(&ClassName::Method);
  DoWorkPointer(&ClassName::Method);
}

Here is an example:

this.configs = new Map<string, string>();
this.configs.set("key", "value");

Demo

Think about your user interface before you do this. I assume (though none of the answers has said so) that you'll be doing this when the document loads using jQuery's ready() function. If a user has already focussed on a different element before the document has loaded (which is perfectly possible) then it's extremely irritating for them to have the focus stolen away.

You could check for this by adding onfocus attributes in each of your <input> elements to record whether the user has already focussed on a form field and then not stealing the focus if they have:

var anyFieldReceivedFocus = false;

function fieldReceivedFocus() {
    anyFieldReceivedFocus = true;
}

function focusFirstField() {
    if (!anyFieldReceivedFocus) {
        // Do jQuery focus stuff
    }
}


<input type="text" onfocus="fieldReceivedFocus()" name="one">
<input type="text" onfocus="fieldReceivedFocus()" name="two">

If you know the data and the action the installed package react on, you simply should add these information to your intent instance before starting it.

If you have access to the AndroidManifest of the other app, you can see all needed information there.

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

for more examples, http://support.microsoft.com/kb/213428 and i believe in the past I've just used

    ActiveWorkbook.Close False

First of all, don't use char* or char[N]. Use std::string, then everything else becomes so easy!

Examples,

std::string s = "Hello";
std::string greet = s + " World"; //concatenation easy!

Easy, isn't it?

Now if you need char const * for some reason, such as when you want to pass to some function, then you can do this:

some_c_api(s.c_str(), s.size()); 

assuming this function is declared as:

some_c_api(char const *input, size_t length);

Explore std::string yourself starting from here:

• Documentation of std::string

Hope that helps.

@sarath how to overwrite the file if i want to run another select * command from a different table and write to same file ?

INSERT OVERWRITE LOCAL DIRECTORY '/home/training/mydata/outputs' SELECT expl , count(expl) as total
FROM ( SELECT explode(splits) as expl FROM ( SELECT split(words,' ') as splits FROM wordcount ) t2 ) t3 GROUP BY expl ;

This is an example to sarath's question

the above is a word count job stored in outputs file which is in local directory :)

The following works on 2008R2+ to produce 'HH:MM':

select
case
when len(replace(replace(replace(right(cast(getdate() as varchar),7),'AM',''),'PM',''),' ','')) = 4
then '0'+ replace(replace(replace(right(cast(getdate() as varchar),7),'AM',''),'PM',''),' ','')
else replace(replace(replace(right(cast(getdate() as varchar),7),'AM',''),'PM',''),' ','') end as [Time]

As Johannes says -- not enough rep to comment directly on his answer -- you can indeed do this as long as all elements' "dimensions are specified as a multiple of the font's size. Meaning, everything where you used %, em or ex units". Although I think % are based on containing element, not font-size.

And you wouldn't normally use these relative units for images, given they are composed of pixels, but there's a trick which makes this a lot more practical.

If you define body{font-size: 62.5%}; then 1em will be equivalent to 10px. As far as I know this works across all main browsers.

Then you can specify your (e.g.) 100px square images with width: 10em; height: 10em; and assuming Firefox's scaling is set to default, the images will be their natural size.

Make body{font-size: 125%}; and everything - including images - wil be double original size.

You should use the filter method rather than map unless you want to mutate the items in the array, in addition to filtering.

eg.

var filteredItems = items.filter(function(item)
{
    return ...some condition...;
});

[Edit: Of course you could always do sourceArray.filter(...).map(...) to both filter and mutate]

This search for a file link explains how to find a file. I did have to muck around with the advice to make it work.

1. cd "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE"
2. tf dir "$/*.sql" /recursive /server:http://mytfsserver:8080/tfs

In the case of the cd command, I performed the cd command because I was looking for the tf.exe file. It was easier to just start from that directory verses adding the whole path. Now that I understand how to make this work, I'd use the absolute path in quotes.

In case of the tf search, I started at the root of the server with $/ and I searched for all files that ended with sql i.e. *.sql. If you don't want to start at the root, then use "$/myproject/*.sql" instead.

Oh! This does not solve the search in file part of the question but my Google search brought me here to find files among other links.

If you want to use free version of font awesome - bootstrap, use this :

npm install --save @fortawesome/fontawesome-free

If you are building angular project, you also need to add these imports in your angular.json :

"styles": [
          "src/styles.css",
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "node_modules/@fortawesome/fontawesome-free/css/fontawesome.min.css"
        ],
        "scripts": [
          "node_modules/jquery/dist/jquery.min.js",
          "node_modules/bootstrap/dist/js/bootstrap.min.js",
          "node_modules/popper.js/dist/umd/popper.min.js",
          "node_modules/@fortawesome/fontawesome-free/js/all.js"
        ]

The (currently) accepted answer by Jerub is correct for python2, but incorrect and may produce garbled results (as Apalala points out in a comment to that solution), for python3. That's because the unicode_escape codec requires its source to be coded in latin-1, not utf-8, as per the official python docs. Hence, in python3 use:

>>> myString="špåm\\nëðþ\\x73"
>>> print(myString)
špåm\nëðþ\x73
>>> decoded_string = myString.encode('latin-1','backslashreplace').decode('unicode_escape')
>>> print(decoded_string)
špåm
ëðþs

This method also avoids the extra unnecessary roundtrip between strings and bytes in metatoaster's comments to Jerub's solution (but hats off to metatoaster for recognizing the bug in that solution).

NotFoundMVC - Provides a user-friendly 404 page whenever a controller, action or route is not found in your ASP.NET MVC3 application. A view called NotFound is rendered instead of the default ASP.NET error page.

You can add this plugin via nuget using: Install-Package NotFoundMvc

NotFoundMvc automatically installs itself during web application start-up. It handles all the different ways a 404 HttpException is usually thrown by ASP.NET MVC. This includes a missing controller, action and route.

Step by Step Installation Guide :

1 - Right click on your Project and Select Manage Nuget Packages...

2 - Search for NotFoundMvc and install it.

3 - Once the installation has be completed, two files will be added to your project. As shown in the screenshots below.

4 - Open the newly added NotFound.cshtml present at Views/Shared and modify it at your will. Now run the application and type in an incorrect url, and you will be greeted with a User friendly 404 page.

No more, will users get errors message like Server Error in '/' Application. The resource cannot be found.

Hope this helps :)

P.S : Kudos to Andrew Davey for making such an awesome plugin.

Off hand, setting the http.agent system property to "" might do the trick (I don't have the code in front of me).

You might get away with:

 System.setProperty("http.agent", "");

but that might require a race between you and initialisation of the URL protocol handler, if it caches the value at startup (actually, I don't think it does).

The property can also be set through JNLP files (available to applets from 6u10) and on the command line:

-Dhttp.agent=

Or for wrapper commands:

-J-Dhttp.agent=

To delete all files and directories within the current directory:

find . -mtime +3 | xargs rm -Rf

Or alternatively, more in line with the OP's original command:

find . -mtime +3 -exec rm -Rf -- {} \;

git gc --aggressive is one way to force the prune process to take place (to be sure: git gc --aggressive --prune=now). You have other commands to clean the repo too. Don't forget though, sometimes git gc alone can increase the size of the repo!

It can be also used after a filter-branch, to mark some directories to be removed from the history (with a further gain of space); see here. But that means nobody is pulling from your public repo. filter-branch can keep backup refs in .git/refs/original, so that directory can be cleaned too.

Finally, as mentioned in this comment and this question; cleaning the reflog can help:

git reflog expire --all --expire=now
git gc --prune=now --aggressive

An even more complete, and possibly dangerous, solution is to remove unused objects from a git repository

Update Feb. 2021, eleven years later: the new git maintenance command (man page) should supersede git gc, and can be scheduled.

The default behaviour for error_log() is to output to the Apache error log. If this isn't happening check your php.ini settings for the error_log directive. Leave it unset to use the Apache log file for the current vhost.

Assuming the key is contained inside the <appSettings> node:

ConfigurationSettings.AppSettings["theKey"];

As for "writing" - put simply, dont.

The web.config is not designed for that, if you're going to be changing a value constantly, put it in a static helper class.

Enter "about:config" into the Firefox address bar and set:

browser.cache.disk.enable = false
browser.cache.memory.enable = false

If developing locally, or using HTML5's new manifest attribute you may have to also set the following in about:config -

browser.cache.offline.enable = false

You could write your own by looking at the JPEG format.

That said, try a pre-existing library like CImg, or Boost's GIL. Or for strictly JPEG's, libjpeg. There is also the CxImage class on CodeProject.

Here's a big list.

I had similar problem. Following solved it:

Change:

recollect_date TIMESTAMP DEFAULT 'CURRENT_TIMESTAMP',

to:

recollect_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

i.e. just remove the quotes around CURRENT_TIMESTAMP.

Hope this helps someone.

This has 2 examples, you can use the one that fits best in your situation.

• use text-align:center on the parent container, or create a container for this.
• if the container has to have a fixed size, use auto left and right margins to center it in the parent container.

note that auto is used with single blocks to center them in the parent space by distrubuting the empty space to the left and right.

I know I am 3 years late on this thread, however still providing my 2 cents for similar cases in future.

I recently faced the same issue/error in my cluster. The JOB would always get to some 80%+ reduction and fail with the same error, with nothing to go on in the execution logs either. Upon multiple iterations and research I found that among the plethora of files getting loaded some were non-compliant with the structure provided for the base table(table being used to insert data into partitioned table).

Point to be noted here is whenever I executed a select query for a particular value in the partitioning column or created a static partition it worked fine as in that case error records were being skipped.

TL;DR: Check the incoming data/files for inconsistency in the structuring as HIVE follows Schema-On-Read philosophy.

It goes something like:

from t1 in db.Table1
join t2 in db.Table2 on t1.field equals t2.field
select new { t1.field2, t2.field3}

It would be nice to have sensible names and fields for your tables for a better example. :)

Update

I think for your query this might be more appropriate:

var dealercontacts = from contact in DealerContact
                     join dealer in Dealer on contact.DealerId equals dealer.ID
                     select contact;

Since you are looking for the contacts, not the dealers.

From your command line, you can do this:

mysql -h *hostname* -P *port number* --database=*database_name* -u *username* -p -e *your SQL query* | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' > *output_file_name.csv*

I'd like to suggest an improvement to previous solution with tracking changes to window width. Instead of keeping your own array of event listeners you can use existing javascript event system and trigger your own event upon width change, and bind event handlers to it.

$(window).bind('myZoomEvent', function() { ... });

function pollZoomFireEvent() 
{ 

    if ( ... width changed ... ) {
        $(window).trigger('myZoomEvent');
    }
}

Throttle/debounce can help with reducing the rate of calls of your handler.

You need to include the protocol scheme:

'http://192.168.1.61:8080/api/call'

Without the http:// part, requests has no idea how to connect to the remote server.

Note that the protocol scheme must be all lowercase; if your URL starts with HTTP:// for example, it won’t find the http:// connection adapter either.

For anyone using entity framework core ending up here. This is how you do it.

# Powershell / Package manager console
Script-Migration

# Cli 
dotnet ef migrations script

You can use the -From and -To parameter to generate an update script to update a database to a specific version.

Script-Migration -From 20190101011200_Initial-Migration -To 20190101021200_Migration-2

https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/#generate-sql-scripts

There are several options to this command.

The from migration should be the last migration applied to the database before running the script. If no migrations have been applied, specify 0 (this is the default).

The to migration is the last migration that will be applied to the database after running the script. This defaults to the last migration in your project.

An idempotent script can optionally be generated. This script only applies migrations if they haven't already been applied to the database. This is useful if you don't exactly know what the last migration applied to the database was or if you are deploying to multiple databases that may each be at a different migration.

Were you expecting player to be a dict rather than a list?

>>> player=[1,2,3]
>>> player["score"]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list indices must be integers, not str
>>> player={'score':1, 'age': 2, "foo":3}
>>> player['score']
1

Set the connection string in your config file:

<connectionStrings>
    <add name="ConnString"
         connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\gadgetDatabase.mdf;Integrated Security=True" />
</connectionStrings>

In windows for me it kept saying "id_ed25135: No such file or directory" upon entering above commands. So I went to the folder, copied the path within folder explorer and added "\id_ed25135" at the end.

This is what I ended up typing and worked:
ssh-keygen -p -f C:\Users\john\.ssh\id_ed25135

This worked. Because for some reason, in Cmder the default path was something like this C:\Users\capit/.ssh/id_ed25135 (some were backslashes: "\" and some were forward slashes: "/")

You can also do like this-

 std::map<char, int>::iterator it = m.find('c'); 
 if (it != m.end())
 (*it).second = 42;

There are two important points to the Swift 2 error handling model: exhaustiveness and resiliency. Together, they boil down to your do/catch statement needing to catch every possible error, not just the ones you know you can throw.

Notice that you don't declare what types of errors a function can throw, only whether it throws at all. It's a zero-one-infinity sort of problem: as someone defining a function for others (including your future self) to use, you don't want to have to make every client of your function adapt to every change in the implementation of your function, including what errors it can throw. You want code that calls your function to be resilient to such change.

Because your function can't say what kind of errors it throws (or might throw in the future), the catch blocks that catch it errors don't know what types of errors it might throw. So, in addition to handling the error types you know about, you need to handle the ones you don't with a universal catch statement -- that way if your function changes the set of errors it throws in the future, callers will still catch its errors.

do {
    let sandwich = try makeMeSandwich(kitchen)
    print("i eat it \(sandwich)")
} catch SandwichError.NotMe {
    print("Not me error")
} catch SandwichError.DoItYourself {
    print("do it error")
} catch let error {
    print(error.localizedDescription)
}

But let's not stop there. Think about this resilience idea some more. The way you've designed your sandwich, you have to describe errors in every place where you use them. That means that whenever you change the set of error cases, you have to change every place that uses them... not very fun.

The idea behind defining your own error types is to let you centralize things like that. You could define a description method for your errors:

extension SandwichError: CustomStringConvertible {
    var description: String {
        switch self {
            case NotMe: return "Not me error"
            case DoItYourself: return "Try sudo"
        }
    }
}

And then your error handling code can ask your error type to describe itself -- now every place where you handle errors can use the same code, and handle possible future error cases, too.

do {
    let sandwich = try makeMeSandwich(kitchen)
    print("i eat it \(sandwich)")
} catch let error as SandwichError {
    print(error.description)
} catch {
    print("i dunno")
}

This also paves the way for error types (or extensions on them) to support other ways of reporting errors -- for example, you could have an extension on your error type that knows how to present a UIAlertController for reporting the error to an iOS user.

Googling around, the popular answer seems to be "just turn off safe mode":

SET SQL_SAFE_UPDATES = 0;
DELETE FROM instructor WHERE salary BETWEEN 13000 AND 15000;
SET SQL_SAFE_UPDATES = 1;

If I'm honest, I can't say I've ever made a habit of running in safe mode. Still, I'm not entirely comfortable with this answer since it just assumes you should go change your database config every time you run into a problem.

So, your second query is closer to the mark, but hits another problem: MySQL applies a few restrictions to subqueries, and one of them is that you can't modify a table while selecting from it in a subquery.

Quoting from the MySQL manual, Restrictions on Subqueries:

In general, you cannot modify a table and select from the same table in a subquery. For example, this limitation applies to statements of the following forms:

DELETE FROM t WHERE ... (SELECT ... FROM t ...);
UPDATE t ... WHERE col = (SELECT ... FROM t ...);
{INSERT|REPLACE} INTO t (SELECT ... FROM t ...);

Exception: The preceding prohibition does not apply if you are using a subquery for the modified table in the FROM clause. Example:

UPDATE t ... WHERE col = (SELECT * FROM (SELECT ... FROM t...) AS _t ...);

Here the result from the subquery in the FROM clause is stored as a temporary table, so the relevant rows in t have already been selected by the time the update to t takes place.

That last bit is your answer. Select target IDs in a temporary table, then delete by referencing the IDs in that table:

DELETE FROM instructor WHERE id IN (
  SELECT temp.id FROM (
    SELECT id FROM instructor WHERE salary BETWEEN 13000 AND 15000
  ) AS temp
);

SQLFiddle demo.

What do you think about this approach?

with open(filename) as data:
    datalines = (line.rstrip('\r\n') for line in data)
    for line in datalines:
        ...do something awesome...

Generator expression avoids loading whole file into memory and with ensures closing the file

Error was due to file name of the lambda function. While creating the lambda function it will ask for Lambda function handler. You have to name it as your Python_File_Name.Method_Name. In this scenario I named it as lambda.lambda_handler (lambda.py is the file name).

Please find below the snapshot.

I have a slight preference for BETWEEN because it makes it instantly clear to the reader that you are checking one field for a range. This is especially true if you have similar field names in your table.

If, say, our table has both a transactiondate and a transitiondate, if I read

transactiondate between ...

I know immediately that both ends of the test are against this one field.

If I read

transactiondate>='2009-04-17' and transactiondate<='2009-04-22'

I have to take an extra moment to make sure the two fields are the same.

Also, as a query gets edited over time, a sloppy programmer might separate the two fields. I've seen plenty of queries that say something like

where transactiondate>='2009-04-17'
  and salestype='A'
  and customernumber=customer.idnumber
  and transactiondate<='2009-04-22'

If they try this with a BETWEEN, of course, it will be a syntax error and promptly fixed.

The git solution for such scenarios is setting SKIP-WORKTREE BIT. Run only the following command:

git update-index --skip-worktree .classpath .gitignore

It is used when you want git to ignore changes of files that are already managed by git and exist on the index. This is a common use case for config files.

Running git rm --cached doesn't work for the scenario mentioned in the question. If I simplify the question, it says:

How to have .classpath and .project on the repo while each one can change it locally and git ignores this change?

As I commented under the accepted answer, the drawback of git rm --cached is that it causes a change in the index, so you need to commit the change and then push it to the remote repository. As a result, .classpath and .project won't be available on the repo while the PO wants them to be there so anyone that clones the repo for the first time, they can use it.

What is SKIP-WORKTREE BIT?

Based on git documentaion:

Skip-worktree bit can be defined in one (long) sentence: When reading an entry, if it is marked as skip-worktree, then Git pretends its working directory version is up to date and read the index version instead. Although this bit looks similar to assume-unchanged bit, its goal is different from assume-unchanged bit’s. Skip-worktree also takes precedence over assume-unchanged bit when both are set.

(in reply to @rshdev, and to avoid having to recompile vim with +xterm_clipboard per @nelstrom in comments on OP)

there's a program called xclip that works like putclip on Ubuntu 11:

:%!xclip -sel clip
u

it's not installed by default. to install, use:

sudo apt-get install xclip

var versionAttrib = new AssemblyName(Assembly.GetExecutingAssembly().FullName);

You're simply after the Array.Exists function (or the Contains extension method if you're using .NET 3.5, which is slightly more convenient).

Use

$route.reload();

remember to inject $route to your controller.

If you need to refer to your host computer's localhost, such as when you want the emulator client to contact a server running on the same host, use the alias 10.0.2.2 to refer to the host computer's loopback interface. From the emulator's perspective, localhost (127.0.0.1) refers to its own loopback interface.More details: http://developer.android.com/guide/faq/commontasks.html#localhostalias

Update on 11 December 2015

Username + password is no longer a recommended solution. This is due to

I tried this and Gmail sent the email used as username in this code an email saying that We recently blocked a sign-in attempt to your Google Account, and directed me to this support page: support.google.com/accounts/answer/6010255 so it looks for it to work, the email account being used to send needs to reduce their own security

Google had released Gmail API - https://developers.google.com/gmail/api/?hl=en. We should use oAuth2 method, instead of username + password.

Here's the code snippet to work with Gmail API.

        Session session = Session.getDefaultInstance(props, null);

        MimeMessage email = new MimeMessage(session);
        InternetAddress tAddress = new InternetAddress(to);
        InternetAddress cAddress = cc.isEmpty() ? null : new InternetAddress(cc);
        InternetAddress fAddress = new InternetAddress(from);

        email.setFrom(fAddress);
        if (cAddress != null) {
            email.addRecipient(javax.mail.Message.RecipientType.CC, cAddress);
        }
        email.addRecipient(javax.mail.Message.RecipientType.TO, tAddress);
        email.setSubject(subject);
        email.setText(bodyText);
        return email;
    }

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        email.writeTo(baos);

        Message message = new Message();
        message.setRaw(encodedEmail);
        return message;
    }

Just add this git config --global http.sslVerify false , so that it doesn't check the certificate and it should work just fine

Yes you can...

PDFs have Javascript support. I needed to have auto print capabilities when a PHP-generated PDF was created and I was able to use FPDF to get it to work:

http://www.fpdf.org/en/script/script36.php

You want the String.strip(s[, chars]) function, which will strip out whitespace characters or whatever characters (such as '\n') you specify in the chars argument.

See http://docs.python.org/release/2.3/lib/module-string.html

By reading online (tables tutorial) it seems tables behave like arrays so you're looking for:

Way1

names = {'John', 'Joe', 'Steve'}
for i = 1,3 do print( names[i] ) end

Way2

names = {'John', 'Joe', 'Steve'}
for k,v in pairs(names) do print(v) end

Way1 uses the table index/key , on your table names each element has a key starting from 1, for example:

names = {'John', 'Joe', 'Steve'}
print( names[1] ) -- prints John

So you just make i go from 1 to 3.

On Way2 instead you specify what table you want to run and assign a variable for its key and value for example:

names = {'John', 'Joe', myKey="myValue" }
for k,v in pairs(names) do print(k,v) end

prints the following:

1   John
2   Joe
myKey   myValue

If you want to append contents of 3 files into one file, then the following command will be a good choice:

cat file1 file2 file3 | tee -a file4 > /dev/null

It will combine the contents of all files into file4, throwing console output to /dev/null.

Here's how to reliably this sort of thing in MS SQL Server Management Studio 2008 (may work for other versions too):

1. In the Object Explorer Tree, right click the root database server (with the green arrow), then click activity monitor.
2. Open the processes tab in the activity monitor, select the 'databases' drop down menu, and filter by the database you want.
3. Right click the DB in Object Explorer and start a 'Tasks -> Take Offline' task. Leave this running in the background while you...
4. Safely shut down whatever you can.
5. Kill all remaining processes from the process tab.
6. Bring the DB back online.
7. Rename the DB.
8. Bring your service back online and point it to the new DB.

Just wanted to point out that the accepted answer has a couple of limitations (which I discovered when I tried to use it)

1. As written, it actually keeps recalculating the font size based on a ratio of the previous font size... thus after just a couple of calls it has rendered the font size as much too large. (eg Start with 12 point as your DESIGNED Font, expand the label by just 1 pixel, and the published code will calculate the Font size as 12 * (say) 1.2 (ratio of field space to text) = 14.4 or 14 point font. 1 more Pixel and call and you are at 16 point !).

It is thus not suitable (without adaptation) for use in a repeated-call setting (eg a ComponentResizedListener, or a custom/modified LayoutManager).

The listed code effectively assumes a starting size of 10 pt but refers to the current font size and is thus suitable for calling once (to set the size of the font when the label is created). It would work better in a multi-call environment if it did int newFontSize = (int) (widthRatio * 10); rather than int newFontSize = (int)(labelFont.getSize() * widthRatio);

2. Because it uses new Font(labelFont.getName(), Font.PLAIN, fontSizeToUse)) to generate the new font, there is no support for Bolding, Italic or Color etc from the original font in the updated font. It would be more flexible if it made use of labelFont.deriveFont instead.

3. The solution does not provide support for HTML label Text. (I know that was probably not ever an intended outcome of the answer code offered, but as I had an HTML-text JLabel on my JPanel I formally discovered the limitation. The FontMetrics.stringWidth() calculates the text length as inclusive of the width of the html tags - ie as simply more text)

I recommend looking at the answer to this SO question where trashgod's answer points to a number of different answers (including this one) to an almost identical question. On that page I will provide an additional answer that speeds up one of the other answers by a factor of 30-100.

Yes: you can sort using a custom comparison function:

std::sort(info.begin(), info.end(), my_custom_comparison);

my_custom_comparison needs to be a function or a class with an operator() overload (a functor) that takes two data objects and returns a bool indicating whether the first is ordered prior to the second (i.e., first < second). Alternatively, you can overload operator< for your class type data; operator< is the default ordering used by std::sort.

Either way, the comparison function must yield a strict weak ordering of the elements.

For me, the problem was passing in a larger than normally expected HTTP header. I resolved it by setting maxHttpHeaderSize="1048576" attribute on the Connector node in server.xml.

Very similar to previous responses, but the is from the current directory, looks at any file and only for ones that are 4 days old. This is what I needed for my research and the above answers were all very helpful. Thanks.

Get-ChildItem -Path . -Recurse| ? {$_.LastWriteTime -gt (Get-Date).AddDays(-4)}

Here in simpler words:

DOM

• Tree model parser (Object based) (Tree of nodes).

• DOM loads the file into the memory and then parse- the file.

• Has memory constraints since it loads the whole XML file before parsing.

• DOM is read and write (can insert or delete nodes).

• If the XML content is small, then prefer DOM parser.

• Backward and forward search is possible for searching the tags and evaluation of the information inside the tags. So this gives the ease of navigation.

• Slower at run time.

SAX

• Event based parser (Sequence of events).

• SAX parses the file as it reads it, i.e. parses node by node.

• No memory constraints as it does not store the XML content in the memory.

• SAX is read only i.e. can’t insert or delete the node.

• Use SAX parser when memory content is large.

• SAX reads the XML file from top to bottom and backward navigation is not possible.

• Faster at run time.

In my case I was trying to simply load a file directly under the lib dir.

Within application.rb...

require '/lib/this_file.rb' 

wasn't working, even in console and then when I tried

require './lib/this_file.rb' 

and rails loads the file perfectly.

I'm still pretty noob and I'm not sure why this works but it works. If someone would like to explain it to me I'd appreciate it :D I hope this helps someone either way.

As of API 21, you should use the getDrawable(int, Theme) method instead of getDrawable(int), as it allows you to fetch a drawable object associated with a particular resource ID for the given screen density/theme. Calling the deprecated getDrawable(int) method is equivalent to calling getDrawable(int, null).

You should use the following code from the support library instead:

ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

Using this method is equivalent to calling:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    return resources.getDrawable(id, context.getTheme());
} else {
    return resources.getDrawable(id);
}

For test navegation on Express:

const request = require('supertest');
const server = require('../bin/www');

describe('navegation', () => {
    it('login page', function(done) {
        this.timeout(4000);
        const timeOut = setTimeout(done, 3500);

        request(server)
            .get('/login')
            .expect(200)
            .then(res => {
                res.text.should.include('Login');
                clearTimeout(timeOut);
                done();
            })
            .catch(err => {
                console.log(this.test.fullTitle(), err);
                clearTimeout(timeOut);
                done(err);
            });
    });
});

In the example the test time is 4000 (4s).

Note: setTimeout(done, 3500) is minor for than done is called within the time of the test but clearTimeout(timeOut) it avoid than used all these time.

@A-312's solution may cause memory problems as it may create a huge array if /xampp/htdocs/WORK contains a lot of files and folders.

If you have PHP 7 then you can use Generators and optimize PHP's memory like this:

function getDirContents($dir) {
    $files = scandir($dir);
    foreach($files as $key => $value){

        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(!is_dir($path)) {
            yield $path;

        } else if($value != "." && $value != "..") {
           yield from getDirContents($path);
           yield $path;
        }
    }
}

foreach(getDirContents('/xampp/htdocs/WORK') as $value) {
    echo $value."\n";
}

yield from

np.asscalar(a) is deprecated since NumPy v1.16, use a.item() instead.

For example:

a = np.array([[0.6813]])
print(a.item())

gives:

0.6813

That what manual says about setOnClickListener method is:

public void setOnClickListener (View.OnClickListener l)

Added in API level 1 Register a callback to be invoked when this view is clicked. If this view is not clickable, it becomes clickable.

Parameters

l View.OnClickListener: The callback that will run

And normally you have to use it like this

public class ExampleActivity extends Activity implements OnClickListener {
    protected void onCreate(Bundle savedValues) {
        ...
        Button button = (Button)findViewById(R.id.corky);
        button.setOnClickListener(this);
    }

    // Implement the OnClickListener callback
    public void onClick(View v) {
      // do something when the button is clicked
    }
    ...
}

Take a look at this lesson as well Building a Simple Calculator using Android Studio.

Here's what worked for me:

$a = Get-ChildItem \\server\XXX\Received_Orders\*.* | Where{$_.LastWriteTime -ge (Get-Date).AddDays(-7)}
if ($a = (Get-ChildItem \\server\XXX\Received_Orders\*.* | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-7)}  
#Im using the -gt switch instead of -ge
{}
Else
{
'STORE XXX HAS NOT RECEIVED ANY ORDERS IN THE PAST 7 DAYS'
}


$b = Get-ChildItem \\COMP NAME\Folder\*.* | Where{$_.LastWriteTime -ge (Get-Date).AddDays(-1)}
if ($b = (Get-ChildItem \\COMP NAME\TFolder\*.* | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-1)))}
{}
Else
{
'STORE XXX DID NOT RUN ITS BACKUP LAST NIGHT'
}

If you working with numpy, you can use the following solution which also works with negative numbers (it's also working on arrays)

import numpy as np
def round_down(num):
    if num < 0:
        return -np.ceil(abs(num))
    else:
        return np.int32(num)
round_down = np.vectorize(round_down)

round_down([-1.1, -1.5, -1.6, 0, 1.1, 1.5, 1.6])
> array([-2., -2., -2.,  0.,  1.,  1.,  1.])

I think it will also work if you just use the math module instead of numpy module.

Your container will exit as the command you gave it will end. Use the following options to keep it live:

• -i Keep STDIN open even if not attached.
• -t Allocate a pseudo-TTY.

So your new run command is:

docker run -it -d shykes/pybuilder bin/bash

If you would like to attach to an already running container:

docker exec -it CONTAINER_ID /bin/bash

In these examples /bin/bash is used as the command.

Archeology

itoa was a non-standard helper function designed to complement the atoi standard function, and probably hiding a sprintf (Most its features can be implemented in terms of sprintf): http://www.cplusplus.com/reference/clibrary/cstdlib/itoa.html

The C Way

Use sprintf. Or snprintf. Or whatever tool you find.

Despite the fact some functions are not in the standard, as rightly mentioned by "onebyone" in one of his comments, most compiler will offer you an alternative (e.g. Visual C++ has its own _snprintf you can typedef to snprintf if you need it).

The C++ way.

Use the C++ streams (in the current case std::stringstream (or even the deprecated std::strstream, as proposed by Herb Sutter in one of his books, because it's somewhat faster).

Conclusion

You're in C++, which means that you can choose the way you want it:

• The faster way (i.e. the C way), but you should be sure the code is a bottleneck in your application (premature optimizations are evil, etc.) and that your code is safely encapsulated to avoid risking buffer overruns.

• The safer way (i.e., the C++ way), if you know this part of the code is not critical, so better be sure this part of the code won't break at random moments because someone mistook a size or a pointer (which happens in real life, like... yesterday, on my computer, because someone thought it "cool" to use the faster way without really needing it).

Old thread, but still a valid concern. I noticed some good responses about security, and avoiding use of 'security through obscurity', but the actual technical methods given were not sufficient in my eyes. Things I must say before I contribute my method:

• NEVER store a password in clear text...EVER!
• NEVER store a user's hashed password in more than one location in your database. Your server backend is always capable of pulling the hashed password from the users table. It's not more efficient to store redundant data in lieu of additional DB transactions, the inverse is true.
• Your Session ID's should be unique, so no two users could ever share an ID, hence the purpose of an ID (could your Driver's License ID number ever match another persons? No.) This generates a two-piece unique combination, based on 2 unique strings. Your Sessions table should use the ID as the PK. To allow multiple devices to be trusted for auto-signin, use another table for trusted devices which contains the list of all validated devices (see my example below), and is mapped using the username.
• It serves no purpose to hash known data into a cookie, the cookie can be copied. What we are looking for is a complying user device to provide authentic information that cannot be obtained without an attacker compromising the user's machine (again, see my example). This would mean, however, that a legitimate user who forbids his machine's static information (i.e. MAC address, device hostname, useragent if restricted by browser, etc.) from remaining consistent (or spoofs it in the first place) will not be able to use this feature. But if this is a concern, consider the fact that you are offering auto-signin to users whom identify themselves uniquely, so if they refuse to be known by spoofing their MAC, spoofing their useragent, spoofing/changing their hostname, hiding behind proxies, etc., then they are not identifiable, and should never be authenticated for an automatic service. If you want this, you need to look into smart-card access bundled with client-side software that establishes identity for the device being used.

That all being said, there are two great ways to have auto-signin on your system.

First, the cheap, easy way that puts it all on someone else. If you make your site support logging in with, say, your google+ account, you probably have a streamlined google+ button that will log the user in if they are already signed into google (I did that here to answer this question, as I am always signed into google). If you want the user automatically signed in if they are already signed in with a trusted and supported authenticator, and checked the box to do so, have your client-side scripts perform the code behind the corresponding 'sign-in with' button before loading, just be sure to have the server store a unique ID in an auto-signin table that has the username, session ID, and the authenticator used for the user. Since these sign-in methods use AJAX, you are waiting for a response anyway, and that response is either a validated response or a rejection. If you get a validated response, use it as normal, then continue loading the logged in user as normal. Otherwise, the login failed, but don't tell the user, just continue as not logged in, they will notice. This is to prevent an attacker who stole cookies (or forged them in an attempt to escalate privileges) from learning that the user auto-signs into the site.

This is cheap, and might also be considered dirty by some because it tries to validate your potentially already signed in self with places like Google and Facebook, without even telling you. It should, however, not be used on users who have not asked to auto-signin your site, and this particular method is only for external authentication, like with Google+ or FB.

Because an external authenticator was used to tell the server behind the scenes whether or not a user was validated, an attacker cannot obtain anything other than a unique ID, which is useless on its own. I'll elaborate:

• User 'joe' visits site for first time, Session ID placed in cookie 'session'.
• User 'joe' Logs in, escalates privileges, gets new Session ID and renews cookie 'session'.
• User 'joe' elects to auto-signin using google+, gets a unique ID placed in cookie 'keepmesignedin'.
• User 'joe' has google keep them signed in, allowing your site to auto-signin the user using google in your backend.
• Attacker systematically tries unique IDs for 'keepmesignedin' (this is public knowledge handed out to every user), and is not signed into anywhere else; tries unique ID given to 'joe'.
• Server receives Unique ID for 'joe', pulls match in DB for a google+ account.
• Server sends Attacker to login page that runs an AJAX request to google to login.
• Google server receives request, uses its API to see Attacker is not logged in currently.
• Google sends response that there is no currently signed in user over this connection.
• Attacker's page receives response, script automatically redirects to login page with a POST value encoded in the url.
• Login page gets the POST value, sends the cookie for 'keepmesignedin' to an empty value and a valid until date of 1-1-1970 to deter an automatic attempt, causing the Attacker's browser to simply delete the cookie.
• Attacker is given normal first-time login page.

No matter what, even if an attacker uses an ID that does not exist, the attempt should fail on all attempts except when a validated response is received.

This method can and should be used in conjunction with your internal authenticator for those who sign into your site using an external authenticator.

=========

Now, for your very own authenticator system that can auto-signin users, this is how I do it:

DB has a few tables:

TABLE users:
UID - auto increment, PK
username - varchar(255), unique, indexed, NOT NULL
password_hash - varchar(255), NOT NULL
...

Note that the username is capable of being 255 characters long. I have my server program limit usernames in my system to 32 characters, but external authenticators might have usernames with their @domain.tld be larger than that, so I just support the maximum length of an email address for maximum compatibility.

TABLE sessions:
session_id - varchar(?), PK
session_token - varchar(?), NOT NULL
session_data - MediumText, NOT NULL

Note that there is no user field in this table, because the username, when logged in, is in the session data, and the program does not allow null data. The session_id and the session_token can be generated using random md5 hashes, sha1/128/256 hashes, datetime stamps with random strings added to them then hashed, or whatever you would like, but the entropy of your output should remain as high as tolerable to mitigate brute-force attacks from even getting off the ground, and all hashes generated by your session class should be checked for matches in the sessions table prior to attempting to add them.

TABLE autologin:
UID - auto increment, PK
username - varchar(255), NOT NULL, allow duplicates
hostname - varchar(255), NOT NULL, allow duplicates
mac_address - char(23), NOT NULL, unique
token - varchar(?), NOT NULL, allow duplicates
expires - datetime code

MAC addresses by their nature are supposed to be UNIQUE, therefore it makes sense that each entry has a unique value. Hostnames, on the other hand, could be duplicated on separate networks legitimately. How many people use "Home-PC" as one of their computer names? The username is taken from the session data by the server backend, so manipulating it is impossible. As for the token, the same method to generate session tokens for pages should be used to generate tokens in cookies for the user auto-signin. Lastly, the datetime code is added for when the user would need to revalidate their credentials. Either update this datetime on user login keeping it within a few days, or force it to expire regardless of last login keeping it only for a month or so, whichever your design dictates.

This prevents someone from systematically spoofing the MAC and hostname for a user they know auto-signs in. NEVER have the user keep a cookie with their password, clear text or otherwise. Have the token be regenerated on each page navigation, just as you would the session token. This massively reduces the likelihood that an attacker could obtain a valid token cookie and use it to login. Some people will try to say that an attacker could steal the cookies from the victim and do a session replay attack to login. If an attacker could steal the cookies (which is possible), they would certainly have compromised the entire device, meaning they could just use the device to login anyway, which defeats the purpose of stealing cookies entirely. As long as your site runs over HTTPS (which it should when dealing with passwords, CC numbers, or other login systems), you have afforded all the protection to the user that you can within a browser.

One thing to keep in mind: session data should not expire if you use auto-signin. You can expire the ability to continue the session falsely, but validating into the system should resume the session data if it is persistent data that is expected to continue between sessions. If you want both persistent AND non-persistent session data, use another table for persistent session data with the username as the PK, and have the server retrieve it like it would the normal session data, just use another variable.

Once a login has been achieved in this way, the server should still validate the session. This is where you can code expectations for stolen or compromised systems; patterns and other expected results of logins to session data can often lead to conclusions that a system was hijacked or cookies were forged in order to gain access. This is where your ISS Tech can put rules that would trigger an account lockdown or auto-removal of a user from the auto-signin system, keeping attackers out long enough for the user to determine how the attacker succeeded and how to cut them off.

As a closing note, be sure that any recovery attempt, password changes, or login failures past the threshold result in auto-signin being disabled until the user validates properly and acknowledges this has occurred.

I apologize if anyone was expecting code to be given out in my answer, that's not going to happen here. I will say that I use PHP, jQuery, and AJAX to run my sites, and I NEVER use Windows as a server... ever.

To set the range of the x-axis, you can use set_xlim(left, right), here are the docs

Update:

It looks like you want an identical plot, but only change the 'tick values', you can do that by getting the tick values and then just changing them to whatever you want. So for your need it would be like this:

ticks = your_plot.get_xticks()*10**9
your_plot.set_xticklabels(ticks)

There should be a 'Run Script' into 'Build Phases' with this: '/usr/local/bin/carthage copy-frameworks'

On the 'Input Files' of that 'Run Script', you should add the path to your libraries. Like this:

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

You can use sklearn.preprocessing:

from sklearn.preprocessing import normalize
data = np.array([
    [1000, 10, 0.5],
    [765, 5, 0.35],
    [800, 7, 0.09], ])
data = normalize(data, axis=0, norm='max')
print(data)
>>[[ 1.     1.     1.   ]
[ 0.765  0.5    0.7  ]
[ 0.8    0.7    0.18 ]]

Perhaps you should check NLS_DATE_FORMAT and use the date string conforming the format. Or you can use to_date function within the INSERT statement, like the following:

insert into visit
values(123456, 
       to_date('19-JUN-13', 'dd-mon-yy'),
       to_date('13-AUG-13 12:56 A.M.', 'dd-mon-yyyy hh:mi A.M.'));

Additionally, Oracle DATE stores date and time information together.

Array elements in Java are initialized to default values when created. For numbers this means they are initialized to 0, for references they are null and for booleans they are false.

To fill the array with something else you can use Arrays.fill() or as part of the declaration

int[] a = new int[] {0, 0, 0, 0};

There are no shortcuts in Java to fill arrays with arithmetic series as in some scripting languages.

To go twice as fast by using multiple processor cores HPCsharp nuget package provides:

list.ToArrayPar();

git diff for unstaged changes.

git diff --cached for staged changes.

git diff HEAD for both staged and unstaged changes.

So i tried everything in this tread and nothing worked for me ... Turns out that on version 2.24 of Git (the one that comes with cpanel at the time of this answer), you don't need to do this

echo "wpm/*" >> .git/info/sparse-checkout

all you need is the folder name

wpm/*

So in short you do this

git config core.sparsecheckout true

you then edit the .git/info/sparse-checkout and add the folder names (one per line) with /* at the end to get subfolders and files

wpm/*

Save and run the checkout command

git checkout master

The result was the expected folder from my repo and nothing else Upvote if this worked for you

All DECLAREs need to be at the top. ie.

delimiter //

CREATE TRIGGER pgl_new_user 
AFTER INSERT ON users FOR EACH ROW
BEGIN
    DECLARE m_user_team_id integer;
    DECLARE m_projects_id integer;
    DECLARE cur CURSOR FOR SELECT project_id FROM user_team_project_relationships WHERE user_team_id = m_user_team_id;

    SET @m_user_team_id := (SELECT id FROM user_teams WHERE name = "pgl_reporters");

    OPEN cur;
        ins_loop: LOOP
            FETCH cur INTO m_projects_id;
            IF done THEN
                LEAVE ins_loop;
            END IF;
            INSERT INTO users_projects (user_id, project_id, created_at, updated_at, project_access) 
            VALUES (NEW.id, m_projects_id, now(), now(), 20);
        END LOOP;
    CLOSE cur;
END//

I know this is an old question but I came here first and then discovered the atexit module. I do not know about its cross-platform track record or a full list of caveats yet, but so far it is exactly what I was looking for in trying to handle post-KeyboardInterrupt cleanup on Linux. Just wanted to throw in another way of approaching the problem.

I want to do post-exit clean-up in the context of Fabric operations, so wrapping everything in try/except wasn't an option for me either. I feel like atexit may be a good fit in such a situation, where your code is not at the top level of control flow.

atexit is very capable and readable out of the box, for example:

import atexit

def goodbye():
    print "You are now leaving the Python sector."

atexit.register(goodbye)

You can also use it as a decorator (as of 2.6; this example is from the docs):

import atexit

@atexit.register
def goodbye():
    print "You are now leaving the Python sector."

If you wanted to make it specific to KeyboardInterrupt only, another person's answer to this question is probably better.

But note that the atexit module is only ~70 lines of code and it would not be hard to create a similar version that treats exceptions differently, for example passing the exceptions as arguments to the callback functions. (The limitation of atexit that would warrant a modified version: currently I can't conceive of a way for the exit-callback-functions to know about the exceptions; the atexit handler catches the exception, calls your callback(s), then re-raises that exception. But you could do this differently.)
