As you're dealing with an array of strings, you can simply use array_filter(), which conveniently handles all this for you:

print_r(array_filter($linksArray));

Keep in mind that if no callback is supplied, all entries of array equal to FALSE (see converting to boolean) will be removed. So if you need to preserve elements that are i.e. exact string '0', you will need a custom callback:

// PHP 7.4 and later
print_r(array_filter($linksArray, fn($value) => !is_null($value) && $value !== ''));

// PHP 5.3 and later
print_r(array_filter($linksArray, function($value) { return !is_null($value) && $value !== ''; }));

// PHP < 5.3
print_r(array_filter($linksArray, create_function('$value', 'return $value !== "";')));

It's working for me:

<%= image_tag( root_url + "images/rss.jpg", size: "50x50", :alt => "rss feed") -%>

Please walk me through the commands I should run to figure this out.

The simplest test you can do is to perform 1000 requests, 10 at a time (which approximately simulates 10 concurrent users getting 100 pages each - over the length of the test).

ab -n 1000 -c 10 -k -H "Accept-Encoding: gzip, deflate" http://www.example.com/

-n 1000 is the number of requests to make.

-c 10 tells AB to do 10 requests at a time, instead of 1 request at a time, to better simulate concurrent visitors (vs. sequential visitors).

-k sends the KeepAlive header, which asks the web server to not shut down the connection after each request is done, but to instead keep reusing it.

I'm also sending the extra header Accept-Encoding: gzip, deflate because mod_deflate is almost always used to compress the text/html output 25%-75% - the effects of which should not be dismissed due to it's impact on the overall performance of the web server (i.e., can transfer 2x the data in the same amount of time, etc).

Multiply that by 60, and you have your requests per minute.

To get real world results, you'll want to test Wordpress instead of some static HTML or index.php file because you need to know how everything performs together: including complex PHP code, and multiple MySQL queries...

For example here is the results of testing a fresh install of Wordpress on the same system and WAMP environment (I'm using WampDeveloper, but there are also Xampp, WampServer, and others)...

Requests per second:    18.68 [#/sec] (mean)

That's 37x slower now!

After the load test, there are a number of things you can do to improve the overall performance (Requests Per Second), and also make the web server more stable under greater load (e.g., increasing the -n and the -c tends to crash Apache), that you can read about here:

Here is the complete solution

html code,

create the text anf file upload fields as shown below

    <div class="form-group">
        <div>
            <label for="usr">User Name:</label>
            <input type="text" id="usr" ng-model="model.username">
        </div>
        <div>
            <label for="pwd">Password:</label>
            <input type="password" id="pwd" ng-model="model.password">
        </div><hr>
        <div>
            <div class="col-lg-6">
                <input type="file" file-model="model.somefile"/>
            </div>


        </div>
        <div>
            <label for="dob">Dob:</label>
            <input type="date" id="dob" ng-model="model.dob">
        </div>
        <div>
            <label for="email">Email:</label>
            <input type="email"id="email" ng-model="model.email">
        </div>


        <button type="submit" ng-click="saveData(model)" >Submit</button>

directive code

create a filemodel directive to parse file

.directive('fileModel', ['$parse', function ($parse) {
return {
    restrict: 'A',
    link: function(scope, element, attrs) {
        var model = $parse(attrs.fileModel);
        var modelSetter = model.assign;

        element.bind('change', function(){
            scope.$apply(function(){
                modelSetter(scope, element[0].files[0]);
            });
        });
    }
};}]);

Service code

append the file and fields to form data and do $http.post as shown below remember to keep 'Content-Type': undefined

 .service('fileUploadService', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, username, password, dob, email, uploadUrl){
        var myFormData = new FormData();

        myFormData.append('file', file);
        myFormData.append('username', username);
        myFormData.append('password', password);
        myFormData.append('dob', dob);
        myFormData.append('email', email);


        $http.post(uploadUrl, myFormData, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
            .success(function(){

            })
            .error(function(){
            });
    }
}]);

In controller

Now in controller call the service by sending required data to be appended in parameters,

$scope.saveData  = function(model){
    var file = model.myFile;
    var uploadUrl = "/api/createUsers";
    fileUpload.uploadFileToUrl(file, model.username, model.password, model.dob, model.email, uploadUrl);
};

This question's bit old, but, there's a tricky scenario which also leads to this error:

In controller:

ViewBag.id = //id from querystring
List<string> = GrabDataFromDBByID(ViewBag.id).Select(a=>a.ToString());

The above code will lead to an error in this part: .Select(a=>a.ToString()) because of the below reason: You're passing a ViewBag.id to a method which in compiler, it doesn't know the type, so there might be several methods with the same name and different parameters let's say:

GrabDataFromDBByID(string)
GrabDataFromDBByID(int)
GrabDataFromDBByID(whateverType)

So to prevent this case, either explicitly cast the ViewBag or create another variable storing it.

You could also use the linux sh command and pass it a command that includes the redirection:

string cmd = "/bin/ls > " + filepath;

execl("/bin/sh", "sh", "-c", cmd.c_str(), 0);

You can easily wrap your button tag with tag.Using Url.Action() HTML Helper this will get to navigate to one page to another.

<a href='@Url.Action("YourAction", "YourController")'>
    <input type='button' value='Dummy Button' />
</a>

If you want to navigate with javascript onclick() function then use

<input type='button' value='Dummy Button' onclick='window.location = "@Url.Action("YourAction", "YourController")";' />

MSSQL requires that variables within procedures be DECLAREd and folks use the @Variable syntax (DECLARE @TEXT VARCHAR(25) = 'text'). Also, MS allows for declares within any block in the procedure, unlike mySQL which requires all the DECLAREs at the top.

While good on the command line, I feel using the "set = @variable" within stored procedures in mySQL is risky. There is no scope and variables live across scope boundaries. This is similar to variables in JavaScript being declared without the "var" prefix, which are then the global namespace and create unexpected collisions and overwrites.

I am hoping that the good folks at mySQL will allow DECLARE @Variable at various block levels within a stored procedure. Notice the @ (at sign). The @ sign prefix helps to separate variable names from table column names - as they are often the same. Of course, one can always add an "v" or "l_" prefix, but the @ sign is a handy and succinct way to have the variable name match the column you might be extracting the data from without clobbering it.

MySQL is new to stored procedures and they have done a good job for their first version. It will be a pleaure to see where they take it form here and to watch the server side aspects of the language mature.

For a shorten version. If all the indices are smaller than 10, then use the following:

do i=0,9
   fid=100+i
   fname='OUTPUT'//NCHAR(i+48) //'.txt'
   open(fid, file=fname)
   !....
end do

For a general version:

character(len=5) :: charI
do i = 0,100
   fid = 100 + i
   write(charI,"(A)"), i
   fname ='OUTPUT' // trim(charI) // '.txt'
   open(fid, file=fname)
end do

That's all.

There is a Superuser Roles: root, which is a Built-In Roles, may meet your need.

From [Hive Language Manual][1]:

COALESCE (T v1, T v2, ...)

Will return the first value that is not NULL, or NULL if all values's are NULL

https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-ConditionalFunctions

There is no ForEach extension for IEnumerable; only for List<T>. So you could do

items.ToList().ForEach(i => i.DoStuff());

Alternatively, write your own ForEach extension method:

public static void ForEach<T>(this IEnumerable<T> enumeration, Action<T> action)
{
    foreach(T item in enumeration)
    {
        action(item);
    }
}

It is possible to code even the solution like this for example :

 var loop = function(i, data, callback) {
    if (i < data.length) {
        //TODO("SELECT * FROM stackoverflowUsers;", function(res) {
            //data[i].meta = res;
            console.log(i, data[i].title);
            return loop(i+1, data, errors, callback);
        //});
    } else {
       return callback(data);
    }
};

loop(0, [{"title": "hello"}, {"title": "world"}], function(data) {
    console.log("DONE\n"+data);
});

On the other hand, it is much slower than a "for".

Otherwise, the excellent Async library can do this: https://caolan.github.io/async/docs.html#each

Try this:

filename1 = "G:\\test1.TXT"
filename2 = "G:\\test2.TXT"


with open(filename1) as f1:
   with open(filename2) as f2:
      file1list = f1.read().splitlines()
      file2list = f2.read().splitlines()
      list1length = len(file1list)
      list2length = len(file2list)
      if list1length == list2length:
          for index in range(len(file1list)):
              if file1list[index] == file2list[index]:
                  print file1list[index] + "==" + file2list[index]
              else:                  
                  print file1list[index] + "!=" + file2list[index]+" Not-Equel"
      else:
          print "difference inthe size of the file and number of lines"

The pause command can be used directly in the ide in the html format.

If using java or C you could use Thread.sleep(5000). Time is in milliseconds. Other languages support "sleep 5" or time.sleep(5). you have multiple options for just waiting for a set time.

The method .transpose() converts columns to rows and rows to column, hence you could even write

df.transpose().ix[3]

When in a window, go to GO ---> ENTER LOCATION... And then copy paste this: /opt/lampp/htdocs

Now you are at the htdocs folder. Then you can add your files there, or in a new folder inside this one (for example "myproyects" folder and inside it your files... and then from a navigator you access it by writting: localhost/myproyects/nameofthefile.php

What I did to find it easily everytime, was right click on "myproyects" folder and "Make link..."... then I moved this link I created to the Desktop and then I didn't have to go anymore to the htdocs, but just enter the folder I created in my Desktop.

Hope it helps!!

A visual answer

Imagine a <span> element inside a <div>. If you give the <span> element a height of 100px and a red border for example, it will look like this with

display: inline

display: inline-block

display: block

Code: http://jsfiddle.net/Mta2b/

Elements with display:inline-block are like display:inline elements, but they can have a width and a height. That means that you can use an inline-block element as a block while flowing it within text or other elements.

Difference of supported styles as summary:

• inline: only margin-left, margin-right, padding-left, padding-right
• inline-block: margin, padding, height, width

You need to use web services. In the above code I have php web service to be used which has a callback function which is optional. Assuming you know HTML5 I did not post the html code. In the url you can send the details to the web server.

methods = [(func, getattr(o, func)) for func in dir(o) if callable(getattr(o, func))]

gives an identical list as

methods = inspect.getmembers(o, predicate=inspect.ismethod)

does.

I know this is fairly old but I figured this was as good as any to put this. I found a post from yahoo with a good explanation:

Let's say you have two numbers, 40 and 30.  

  30/40*100 = 75.
  So 30 is 75% of 40.  

  40/30*100 = 133. 
  So 40 is 133% of 30. 

The percentage increase from 30 to 40 is:  
  (40-30)/30 * 100 = 33%  

The percentage decrease from 40 to 30 is:
  (40-30)/40 * 100 = 25%. 

These calculations hold true whatever your two numbers.

Multiple queries tip for those who don't know (past me and future me)

If you're making a single query with the url just ?autoplay=1 works as shown by mjhm's answer

If you're making multiple queries remember the first one begins with a ? while the rest begin with a &

Say you want to turn off related videos but enable autoplay...

Processors today work with many levels of cascading memory areas. So the CPU will have a bunch of memory that is on the CPU chip itself. It has very fast access to this memory. There are different levels of cache each one slower access ( and larger ) than the next, until you get to system memory which is not on the CPU and is relatively much slower to access.

Logically, to the CPU's instruction set you just refer to memory addresses in a giant virtual address space. When you access a single memory address the CPU will go fetch it. in the old days it would fetch just that single address. But today the CPU will fetch a bunch of memory around the bit you asked for, and copy it into the cache. It assumes that if you asked for a particular address that is is highly likely that you are going to ask for an address nearby very soon. For example if you were copying a buffer you would read and write from consecutive addresses - one right after the other.

So today when you fetch an address it checks the first level of cache to see if it already read that address into cache, if it doesn't find it, then this is a cache miss and it has to go out to the next level of cache to find it, until it eventually has to go out into main memory.

Cache friendly code tries to keep accesses close together in memory so that you minimize cache misses.

So an example would be imagine you wanted to copy a giant 2 dimensional table. It is organized with reach row in consecutive in memory, and one row follow the next right after.

If you copied the elements one row at a time from left to right - that would be cache friendly. If you decided to copy the table one column at a time, you would copy the exact same amount of memory - but it would be cache unfriendly.

I was missing this authenticator object argument in the below line

Session session = Session.getInstance(props, new GMailAuthenticator(username, password));

This line solved my problem now I can send mail through my Java application. Rest of the code is simple just like above.

which version are you using?

If the coding standards for the particular codebase I am writing code for specifies which operator should be used, I'll definitely use that. If not, and the code dictates which should be used (not often, can be easily worked around) then I'll use that. Otherwise, probably &&.

Is 'and' more readable than '&&'?

Is it more readable to you. The answer is yes and no depending on many factors including the code around the operator and indeed the person reading it!

|| there is ~ difference?

Yes. See logical operators for || and bitwise operators for ~.

A very easy way to invoke return and non return value subroutines. is using Func and Action respectively. (see also https://msdn.microsoft.com/en-us/library/018hxwa8(v=vs.110).aspx)

Try this this example

using System;

public class Program
{
    private Func<string,string> FunctionPTR = null;  
    private Func<string,string, string> FunctionPTR1 = null;  
    private Action<object> ProcedurePTR = null; 



    private string Display(string message)  
    {  
        Console.WriteLine(message);  
        return null;  
    }  

    private string Display(string message1,string message2)  
    {  
        Console.WriteLine(message1);  
        Console.WriteLine(message2);  
        return null;  
    }  

    public void ObjectProcess(object param)
    {
        if (param == null)
        {
            throw new ArgumentNullException("Parameter is null or missing");
        }
        else 
        {
            Console.WriteLine("Object is valid");
        }
    }


    public void Main(string[] args)  
    {  
        FunctionPTR = Display;  
        FunctionPTR1= Display;  
        ProcedurePTR = ObjectProcess;
        FunctionPTR("Welcome to function pointer sample.");  
        FunctionPTR1("Welcome","This is function pointer sample");   
        ProcedurePTR(new object());
    }  
}

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

Similar to the answer pointed out by @Thomas, This can also be done using ifelse() method of R:

for(i in 1:ncol(data)){
  data[,i]=ifelse(is.na(data[,i]),
                  ave(data[,i],FUN=function(y) mean(y, na.rm = TRUE)),
                  data[,i])
}

where, Arguments to ifelse(TEST, YES , NO) are:-

TEST- logical condition to be checked

YES- executed if the condition is True

NO- else when the condition is False

and ave(x, ..., FUN = mean) is method in R used for calculating averages of subsets of x[]

Another option is to mirror the S3 bucket on your web server and traverse locally. The trick is that the local files are empty and only used as a skeleton. Alternatively, the local files could hold useful meta data that you normally would need to get from S3 (e.g. filesize, mimetype, author, timestamp, uuid). When you provide a URL to download the file, search locally and but provide a link to the S3 address.

Local file traversing is easy and this approach for S3 management is language agnostic. Local file traversing also avoids maintaining and querying a database of files or delays making a series of remote API calls to authenticate and get the bucket contents.

You could allow users to upload files directly to your server via FTP or HTTP and then transfer a batch of new and updated files to Amazon at off peak times by just recursing over the directories for files with any size. On the completion of a file transfer to Amazon, replace the web server file with an empty one of the same name. If a local file has any filesize then serve it directly because its awaiting batch transfer.

As a string is a collection of characters, you can use LINQ extension methods on them:

if (s.Any(c => c == 'a' || c == 'b' || c == 'c')) ...

This will scan the string once and stop at the first occurance, instead of scanning the string once for each character until a match is found.

This can also be used for any expression you like, for example checking for a range of characters:

if (s.Any(c => c >= 'a' && c <= 'c')) ...

MSDN has a sample.

namespace Examples.System.Net
{
    public class WebRequestPostExample
    {
        public static void Main()
        {
            // Create a request using a URL that can receive a post. 
            WebRequest request = WebRequest.Create("http://www.contoso.com/PostAccepter.aspx");
            // Set the Method property of the request to POST.
            request.Method = "POST";
            // Create POST data and convert it to a byte array.
            string postData = "This is a test that posts this string to a Web server.";
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            // Set the ContentType property of the WebRequest.
            request.ContentType = "application/x-www-form-urlencoded";
            // Set the ContentLength property of the WebRequest.
            request.ContentLength = byteArray.Length;
            // Get the request stream.
            Stream dataStream = request.GetRequestStream();
            // Write the data to the request stream.
            dataStream.Write(byteArray, 0, byteArray.Length);
            // Close the Stream object.
            dataStream.Close();
            // Get the response.
            WebResponse response = request.GetResponse();
            // Display the status.
            Console.WriteLine(((HttpWebResponse)response).StatusDescription);
            // Get the stream containing content returned by the server.
            dataStream = response.GetResponseStream();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader(dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd();
            // Display the content.
            Console.WriteLine(responseFromServer);
            // Clean up the streams.
            reader.Close();
            dataStream.Close();
            response.Close();
        }
    }
}

Half (but only half) snarky answer (the other half is bitter disdain of the reality of bureaucracy):

Use vh

Everything is always sized to browser window.

Always allow scroll down, but disable horizontal scroll.

Set body width to be a static 50vh, and never code css that floats or breaks out of the parent div. (If they try to mock up something that looks like it does, clever use of a background gif can throw them off track.) And style only using tables so everything is held rigidly into place as expected. Include a javascript function to undo any ctrl+/- activity the user may do.

Users will hate you, because the site doesn't flow differently based on what they're using (such as text being too small to read on phones). Your coworkers will hate you because nobody in their right mind does this and it will likely break their work (though not yours). Your programming professors will hate you because this is not a good idea. Your UX designer will hate you because it will reveal the corners they cut in designing UX mock-ups that they have to do in order to meet deadlines.

Nearly everyone will hate you, except the people who tell you to make things match the mock-up and to do so quickly. Those people, however (which generally include the project managers), will be ecstatic by your accuracy and fast turn around time. And everyone knows their opinion is the only one that matters to your paycheck.

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

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

Keep in mind that a PDOStatement is Traversable. Given a query:

$query = $dbh->query('
    SELECT
        *
    FROM
        test
');

It can be iterated over:

$it = new IteratorIterator($query);
echo '<p>', iterator_count($it), ' items</p>';

// Have to run the query again unfortunately
$query->execute();
foreach ($query as $row) {
    echo '<p>', $row['title'], '</p>';
}

Or you can do something like this:

$it = new IteratorIterator($query);
$it->rewind();

if ($it->valid()) {
    do {
        $row = $it->current();
        echo '<p>', $row['title'], '</p>';
        $it->next();
    } while ($it->valid());
} else {
    echo '<p>No results</p>';
}

This should do it:

SELECT report_id, computer_id, date_entered
FROM reports AS a
WHERE date_entered = (
    SELECT MAX(date_entered)
    FROM reports AS b
    WHERE a.report_id = b.report_id
      AND a.computer_id = b.computer_id
)

the simplest idea is to add pkg-config --cflags --libs sdl2 while compiling the code.

g++ file.cpp `pkg-config --cflags --libs sdl2`

With git there is a https format

https://github.com/equivalent/we_demand_serverless_ruby.git

This format accepts User + password

https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git

So what you can do is create a new user that will be used just as a bot, add only enough permissions that he can just read the repository you want to load in NPM modules and just have that directly in your packages.json

 Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token

In Select Scopes part, check the on repo: Full control of private repositories

This is so that token can access private repos that user can see

Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)

You need to be sure to push this config only to private repo

Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)

// packages.json


{
  // ....
    "name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
  // ...
}

This code should work:

>>> iter = (i for i in range(50))
>>> sum(1 for _ in iter)
50

Although it does iterate through each item and count them, it is the fastest way to do so.

It also works for when the iterator has no item:

>>> sum(1 for _ in range(0))
0

Of course, it runs forever for an infinite input, so remember that iterators can be infinite:

>>> sum(1 for _ in itertools.count())
[nothing happens, forever]

Also, be aware that the iterator will be exhausted by doing this, and further attempts to use it will see no elements. That's an unavoidable consequence of the Python iterator design. If you want to keep the elements, you'll have to store them in a list or something.

Set the cellspacing attribute of the table to 0.

You can also use the CSS style, border-spacing: 0, but only if you don't need to support older versions of IE.

Without FileReader, we can use URL.createObjectURL method to get the DOMString that represents the object ( our image file ).

Don't forget to validate image extension.

<input type="file" id="files" multiple />
<div class="image-preview"></div>

let file_input = document.querySelector('#files');
let image_preview = document.querySelector('.image-preview');

const handle_file_preview = (e) => {
  let files = e.target.files;
  let length = files.length;

  for(let i = 0; i < length; i++) {
      let image = document.createElement('img');
      // use the DOMstring for source
      image.src = window.URL.createObjectURL(files[i]);
      image_preview.appendChild(image);
  }
}

file_input.addEventListener('change', handle_file_preview);

So you are doing the right thing concerning "-XX:MaxPermSize=512m": it is indeed the correct syntax. You could try to set these options directly to the Catalyna server files so they are used on server start.

Maybe this post will help you!

How to make sure that Tomcat6 reads CATALINA_OPTS on Windows?

The reason why you always got True has already been given, so I'll just offer another suggestion:

If your file is not too large, you can read it into a string, and just use that (easier and often faster than reading and checking line per line):

with open('example.txt') as f:
    if 'blabla' in f.read():
        print("true")

Another trick: you can alleviate the possible memory problems by using mmap.mmap() to create a "string-like" object that uses the underlying file (instead of reading the whole file in memory):

import mmap

with open('example.txt') as f:
    s = mmap.mmap(f.fileno(), 0, access=mmap.ACCESS_READ)
    if s.find('blabla') != -1:
        print('true')

NOTE: in python 3, mmaps behave like bytearray objects rather than strings, so the subsequence you look for with find() has to be a bytes object rather than a string as well, eg. s.find(b'blabla'):

#!/usr/bin/env python3
import mmap

with open('example.txt', 'rb', 0) as file, \
     mmap.mmap(file.fileno(), 0, access=mmap.ACCESS_READ) as s:
    if s.find(b'blabla') != -1:
        print('true')

You could also use regular expressions on mmap e.g., case-insensitive search: if re.search(br'(?i)blabla', s):

Bubble sort can be used here:

 //Time complexity: O(n^2)
public static int[] bubbleSort(final int[] arr) {

    if (arr == null || arr.length <= 1) {
        return arr;
    }

    for (int i = 0; i < arr.length; i++) {
        for (int j = 1; j < arr.length - i; j++) {
            if (arr[j - 1] > arr[j]) {
                arr[j] = arr[j] + arr[j - 1];
                arr[j - 1] = arr[j] - arr[j - 1];
                arr[j] = arr[j] - arr[j - 1];
            }
        }
    }

    return arr;
}

I've modified Greg's answer to suit my case, and it works. Here it is:

$("#note-items").children('.active').hide('slow', function(){ $("#note-items").children('.active').remove(); });

This might happen if you place .cs files in App_Code and changed their build action to compile in a Web Application Project.

Either have the build action for the .cs files in App_Code as Content or change the name of App_Code to something else. I changed the name since intellisense won't fix .cs files marked as content.

Most of the time after the installation of Eclipse eclipse.ini is changed. If you change the jdk in eclipse.ini then eclipse will use this jdk by default.

Let's say you install a new version of Eclipse and you have forgotten to change the eclipse.ini related to the jdk. Then Eclipse finds a jdk for you. Let's say it is java 1.6 that was automatically discovered (you did nothing).

If you use maven (M2E) and you reference a 1.7 jdk then you will see the frustrating message. But normally it is not displayed because you configure the correct jdk in eclipse.ini.

That was my case. I made reference into the pom to a jdk that was not configured into Eclipse.

In the screenshot you can see that 1.7 is configured and seen by Eclipse. In this case, you should make reference into the pom to a jre that is compatible with 1.7! If not -> frustrating message!

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

Expanding upon @aquinas:

Get-something | select -ExpandProperty PropertyName

or

Get-something | select -expand PropertyName

or

Get-something | select -exp PropertyName

I made these suggestions for those that might just be looking for a single-line command to obtain some piece of information and wanted to include a real-world example.

In managing Office 365 via PowerShell, here was an example I used to obtain all of the users/groups that had been added to the "BookInPolicy" list:

Get-CalendarProcessing [email protected] | Select -expand BookInPolicy

Just using "Select BookInPolicy" was cutting off several members, so thank you for this information!

Use:

git diff 15dc8^!

as described in the following fragment of git-rev-parse(1) manpage (or in modern git gitrevisions(7) manpage):

Two other shorthands for naming a set that is formed by a commit and its parent commits exist. The r1^@ notation means all parents of r1. r1^! includes commit r1 but excludes all of its parents.

This means that you can use 15dc8^! as a shorthand for 15dc8^..15dc8 anywhere in git where revisions are needed. For diff command the git diff 15dc8^..15dc8 is understood as git diff 15dc8^ 15dc8, which means the difference between parent of commit (15dc8^) and commit (15dc8).

^{Note: the description in git-rev-parse(1) manpage talks about revision ranges, where it needs to work also for merge commits, with more than one parent. Then r1^! is "r1 --not r1^@" i.e. "r1 ^r1^1 ^r1^2 ..."}

Also, you can use git show COMMIT to get commit description and diff for a commit. If you want only diff, you can use git diff-tree -p COMMIT

You can check /etc/ld.so.preload file content

I fix it by:

echo "" > /etc/ld.so.preload

When I'm just testing a string to see if it is a GUID, I don't really want to create a Guid object that I don't need. So...

public static class GuidEx
{
    public static bool IsGuid(string value)
    {
        Guid x;
        return Guid.TryParse(value, out x);
    }
}

And here's how you use it:

string testMe = "not a guid";
if (GuidEx.IsGuid(testMe))
{
...
}

Using JS and CSS :not pseudoclass

 input {_x000D_
        font-size: 13px;_x000D_
        padding: 5px;_x000D_
        width: 100px;_x000D_
    }_x000D_
_x000D_
    input[value=""] {_x000D_
        border: 2px solid #fa0000;_x000D_
    }_x000D_
_x000D_
    input:not([value=""]) {_x000D_
        border: 2px solid #fafa00;_x000D_
    }

<input type="text" onkeyup="this.setAttribute('value', this.value);" value="" />_x000D_
_x000D_
   

Sort the file randomly and pick first 100 lines:

$ sort -R input | head -n 100 >output

You still need two INSERT statements, but it sounds like you want to get the IDENTITY from the first insert and use it in the second, in which case, you might want to look into OUTPUT or OUTPUT INTO: http://msdn.microsoft.com/en-us/library/ms177564.aspx

With the current version of Visual Studio Code as of this writing (1.22.1), you can find your settings in

• ~/.config/Code/User on Linux (in my case, an, Ubuntu derivative)
• C:\Users\username\AppData\Roaming\Code\User on Windows 10
• ~/Library/Application Support/Code/User/ on Mac OS X (thank you, Christophe De Troyer)

The files are settings.json and keybindings.json. Simply copy them to the target machine.

Your extensions are in

• ~/.vscode/extensions on Linux and Mac OS X
• C:\Users\username\.vscode\extensions on Windows 10 (e.g., essentially the same place)

Alternately, just go to the Extensions, show installed extensions, and install those on your target installation. For me, copying the extensions worked just fine, but it may be extension-specific, particularly if moving between platforms, depending on what the extension does.

w3wp.exe is a process associated with the application pool in IIS. If you have more than one application pool, you will have more than one instance of w3wp.exe running. This process usually allocates large amounts of resources. It is important for the stable and secure running of your computer and should not be terminated.

You can get more information on w3wp.exe here

http://www.processlibrary.com/en/directory/files/w3wp/25761/

Please try to this one

public void Method(Datetime time)
{
    time.toString("yyyy-MM-dd'T'HH:mm:ss"));
}

As no one has mentioned, another way to create a String out of a single char:

String s = Character.toString('X');

Returns a String object representing the specified char. The result is a string of length 1 consisting solely of the specified char.

1. Check the .aws directory under home directory. Windows: C:\Users<home-name>.aws Linux: ~/.aws

2. Under this directory, you will find the config as well as credentials file. It will have the information from the aws configure that you may have run before. IF not, then

3. Run aws configure Enter the access key - secret key - enter secret key region - (ap-southeast-1 or us-east-1 or any other regions) format - (json or leave it blank, it will pick up default values you may simply hit enter)

4. From the Step 2, you should see the config file, open it, it should have the region. Please ensure there is region specified.

5. You may now run the following command to list the buckets aws s3 ls It should work fine.

The other answers are correct that it is usually a bad idea to delete from a list that you're iterating. Reverse iterating avoids the pitfalls, but it is much more difficult to follow code that does that, so usually you're better off using a list comprehension or filter.

There is, however, one case where it is safe to remove elements from a sequence that you are iterating: if you're only removing one item while you're iterating. This can be ensured using a return or a break. For example:

for i, item in enumerate(lst):
    if item % 4 == 0:
        foo(item)
        del lst[i]
        break

This is often easier to understand than a list comprehension when you're doing some operations with side effects on the first item in a list that meets some condition and then removing that item from the list immediately after.

You can use Apply and Lambda to select rows where a column contains any thing in a list. For your scenario :

df[df["col"].apply(lambda x:x not in [word1,word2,word3])]

HTML :

<div class="span4">
  <div class="panel panel-primary">
    <div class="panel-heading">jhdsahfjhdfhs</div>
    <div class="panel-body panel-height">fdoinfds sdofjohisdfj</div>
  </div>
</div>

CSS :

.panel-height {
  height: 100px; / change according to your requirement/
}

In my case i had to move the html code of the element i wanted at the front at the end of the html file, because if one element has z-index and the other doesn't have z index it doesn't work.

Perhaps it has no special meaning and only needs to be rendered in italics to separate it presentationally from the text preceding it.

If it has no special meaning, why does it need to be separated presentationally from the text preceding it? This run of text looks a bit weird, because I’ve italicised it for no reason.

I do take your point though. It’s not uncommon for designers to produce designs that vary visually, without varying meaningfully. I’ve seen this most often with boxes: designers will give us designs including boxes with various combinations of colours, corners, gradients and drop-shadows, with no relation between the styles, and the meaning of the content.

Because these are reasonably complex styles (with associated Internet Explorer issues) re-used in different places, we create classes like box-1, box-2, so that we can re-use the styles.

The specific example of making some text italic is too trivial to worry about though. Best leave minutiae like that for the Semantic Nutters to argue about.

if ($elem.parents('.left').length) {

}

I read all the clunky solutions on the net about how to mask passwords in a batch file, the ones from using a hide.com solution and even the ones that make the text and the background the same color. The hide.com solution works decent, it isn't very secure, and it doesn't work in 64-bit Windows. So anyway, using 100% Microsoft utilities, there is a way!

First, let me explain my use. I have about 20 workstations that auto logon to Windows. They have one shortcut on their desktop - to a clinical application. The machines are locked down, they can't right click, they can't do anything but access the one shortcut on their desktop. Sometimes it is necessary for a technician to kick up some debug applications, browse windows explorer and look at log files without logging the autolog user account off.

So here is what I have done.

Do it however you wish, but I put my two batch files on a network share that the locked down computer has access to.

My solution utilizes 1 main component of Windows - runas. Put a shortcut on the clients to the runas.bat you are about to create. FYI, on my clients I renamed the shortcut for better viewing purposes and changed the icon.

You will need to create two batch files.

I named the batch files runas.bat and Debug Support.bat

runas.bat contains the following code:

cls
@echo off
TITLE CHECK CREDENTIALS 
goto menu

:menu
cls
echo.
echo           ....................................
echo            ~Written by Cajun Wonder 4/1/2010~
echo           ....................................
echo.
@set /p un=What is your domain username? 
if "%un%"=="PUT-YOUR-DOMAIN-USERNAME-HERE" goto debugsupport
if not "%un%"=="PUT-YOUR-DOMAIN-USERNAME-HERE" goto noaccess
echo.
:debugsupport
"%SYSTEMROOT%\system32\runas" /netonly /user:PUT-YOUR-DOMAIN-NAME-HERE\%un% "\\PUT-YOUR-NETWORK-SHARE-PATH-HERE\Debug Support.bat"
@echo ACCESS GRANTED! LAUNCHING THE DEBUG UTILITIES....
@ping -n 4 127.0.0.1 > NUL
goto quit
:noaccess
cls
@echo.
@echo.
@echo.
@echo.
@echo   \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
@echo   \\                                   \\
@echo   \\    Insufficient privileges         \\  
@echo   \\                                    \\
@echo   \\      Call Cajun Wonder             \\
@echo   \\                                    \\
@echo   \\              At                    \\
@echo   \\                                    \\
@echo   \\        555-555-5555                \\
@echo   \\                                    \\
@echo   \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
@ping -n 4 127.0.0.1 > NUL
goto quit
@pause
:quit
@exit

You can add as many if "%un%" and if not "%un%" for all the users you want to give access to. The @ping is my coonass way of making a seconds timer.

So that takes care of the first batch file - pretty simple eh?

Here is the code for Debug Support.bat:

cls
@echo off
TITLE SUPPORT UTILITIES
goto menu

:menu
cls
@echo %username%
echo.
echo           .....................................
echo            ~Written by Cajun Wonder 4/1/2010~
echo           .....................................
echo.
echo What do you want to do? 
echo.
echo [1]  Launch notepad
echo.

:choice
set /P C=[Option]? 
if "%C%"=="1" goto notepad
goto choice

:notepad
echo.
@echo starting notepad....
@ping -n 3 127.0.0.1 > NUL
start notepad
cls
goto menu

I'm not a coder and really just started getting into batch scripting about a year ago, and this round about way that I discovered of masking a password in a batch file is pretty awesome!

I hope to hear that someone other than me is able to get some use out of it!

If you are producing the DataTable from an SQL query, have you considered simply using Dapper instead?

Then, instead of making a SqlCommand with SqlParameters and a DataTable and a DataAdapter and on and on, which you then have to laboriously convert to a class, you just define the class, make the query column names match the field names, and the parameters are bound easily by name. You already have the TankReading class defined, so it will be really simple!

using Dapper;

// Below can be SqlConnection cast to DatabaseConnection, too.
DatabaseConnection connection = // whatever
IEnumerable<TankReading> tankReadings = connection.Query<TankReading>(
   "SELECT * from TankReading WHERE Value = @value",
   new { value = "tank1" } // note how `value` maps to `@value`
);
return tankReadings;

Now isn't that awesome? Dapper is very optimized and will give you darn near equivalent performance as reading directly with a DataAdapter.

If your class has any logic in it at all or is immutable or has no parameterless constructor, then you probably do need to have a DbTankReading class (as a pure POCO/Plain Old Class Object):

// internal because it should only be used in the data source project and not elsewhere
internal sealed class DbTankReading {
   int TankReadingsID { get; set; }
   DateTime? ReadingDateTime { get; set; }
   int ReadingFeet { get; set; }
   int ReadingInches { get; set; }
   string MaterialNumber { get; set; }
   string EnteredBy { get; set; }
   decimal ReadingPounds { get; set; }
   int MaterialID { get; set; }
   bool Submitted { get; set; }
}

You'd use that like this:

IEnumerable<TankReading> tankReadings = connection
   .Query<DbTankReading>(
      "SELECT * from TankReading WHERE Value = @value",
      new { value = "tank1" } // note how `value` maps to `@value`
   )
   .Select(tr => new TankReading(
      tr.TankReadingsID,
      tr.ReadingDateTime,
      tr.ReadingFeet,
      tr.ReadingInches,
      tr.MaterialNumber,
      tr.EnteredBy,
      tr.ReadingPounds,
      tr.MaterialID,
      tr.Submitted
   });

Despite the mapping work, this is still less painful than the data table method. This also lets you perform some kind of logic, though if the logic is any more than very simple straight-across mapping, I'd put the logic into a separate TankReadingMapper class.

Use:

DefaultTableModel model = new DefaultTableModel(); 
JTable table = new JTable(model); 

// Create a couple of columns 
model.addColumn("Col1"); 
model.addColumn("Col2"); 

// Append a row 
model.addRow(new Object[]{"v1", "v2"});

You should be able to access the 2d array with a simple pointer in place. The array[x][y] will be arranged in the pointer as p[0x * width + 0y][0x * width + 1y]...[0x * width + n-1y][1x * width + 0y] etc.

I just want to add some remarks to the great answer by Fredrik.

The Java Language Specification in Section 4.3.1 states

An object is a class instance or an array.

So array has indeed a very special role in Java. I do wonder why.

One could argue that current implementation array is/was important for a better performance. But than it is an internal structure, which should not be exposed.

They could of course have masked the property as a method call and handled it in the compiler but I think it would have been even more confusing to have a method on something that isn't a real class.

I agree with Fredrik, that a smart compiler optimazation would have been the better choice. This would also solve the problem, that even if you use a property for arrays, you have not solved the problem for strings and other (immutable) collection types, because, e.g., string is based on a char array as you can see on the class definition of String:

public final class String implements java.io.Serializable, Comparable<String>, CharSequence {           
    private final char value[]; // ...

And I do not agree with that it would be even more confusing, because array does inherit all methods from java.lang.Object.

As an engineer I really do not like the answer "Because it has been always this way." and wished there would be a better answer. But in this case it seems to be.

tl;dr

In my opinion, it is a design flaw of Java and should not have implemented this way.

For anything with requests to URLs you might want to check out requests. For JSON in particular:

>>> import requests
>>> r = requests.get('https://github.com/timeline.json')
>>> r.json()
[{u'repository': {u'open_issues': 0, u'url': 'https://github.com/...

To pass a NULL to MySQL, you do just that.

INSERT INTO table (field,field2) VALUES (NULL,3)

So, in your code, check if $intLat, $intLng are empty, if they are, use NULL instead of '$intLat' or '$intLng'.

$intLat = !empty($intLat) ? "'$intLat'" : "NULL";
$intLng = !empty($intLng) ? "'$intLng'" : "NULL";

$query = "INSERT INTO data (notes, id, filesUploaded, lat, lng, intLat, intLng)
          VALUES ('$notes', '$id', TRIM('$imageUploaded'), '$lat', '$long', 
                  $intLat, $intLng)";

In Postgres, you can also use the special DISTINCT ON (expression) syntax:

SELECT DISTINCT ON (cname) 
    cname, wmname, avg
FROM 
    makerar 
ORDER BY 
    cname, avg DESC ;

All you need is to make an ajax request to your pythoncode. You can do this with jquery http://api.jquery.com/jQuery.ajax/, or use just javascript

$.ajax({
  type: "POST",
  url: "~/pythoncode.py",
  data: { param: text}
}).done(function( o ) {
   // do something
});

For the record, you can also use a std::stringstream if you want to create the string before it's actually output.

Assuming you are using Python 3.x:

print(*myList, sep='\n')

You can get the same behavior on Python 2.x using from __future__ import print_function, as noted by mgilson in comments.

With the print statement on Python 2.x you will need iteration of some kind, regarding your question about print(p) for p in myList not working, you can just use the following which does the same thing and is still one line:

for p in myList: print p

For a solution that uses '\n'.join(), I prefer list comprehensions and generators over map() so I would probably use the following:

print '\n'.join(str(p) for p in myList) 

Because the numbers after point is only zero, the best solution is to use the Math.Round(MyNumber)

For reference for anyone looking at this question:

If you use the nuget package, it installs a build rule that does the copying for you. (see under System.Data.SQLite.Core.1.0.94.0\build - or whatever version of Core you install).

The nuget installer adds the rule to your project file automatically.

This still doesn't fix the test case problem though. The DeploymentItem (https://stackoverflow.com/a/24411049/89584) approach is the only thing that seems to work there.

• The audio must be placed in the raw folder, if it doesn't exists, create one.
• The raw folder must be inside the res folder
• The name mustn't have any - or special characters in it.

On your activity, you need to have a object MediaPlayer, inside the onCreate method or the onclick method, you have to initialize the MediaPlayer, like MediaPlayer.create(this, R.raw.name_of_your_audio_file), then your audio file ir ready to be played with the call for start(), in your case, since you want it to be placed in a button, you'll have to put it inside the onClick method.

Example:

private Button myButton;
private MediaPlayer mp;
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.myactivity);
        mp = MediaPlayer.create(this, R.raw.gunshot);

        myButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mp.start();
            }
        });
}
}

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

Prefixing the string with an @ indicates that it should be treated as a literal, i.e. no escaping.

For example if your string contains a path you would typically do this:

string path = "c:\\mypath\\to\\myfile.txt";

The @ allows you to do this:

string path = @"c:\mypath\to\myfile.txt";

Notice the lack of double slashes (escaping)

These days you can also use the Web API ResizeObserver.

Simple example:

const resizeObserver = new ResizeObserver(() => {
    console.log('size changed');
});

resizeObserver.observe(document.querySelector('#myElement'));

simple is the best and works in every version.

if a>10: 
    value="b"
else: 
    value="c"

That's usually what stored procedures are for: to implement several SQL statements in a sequence. Using rollbacks, you can ensure that they are treated as one unit of work, ie either they are all executed or none of them are, to keep data consistent.

This:

document.getElementById('myField').onblur();

works because your element (the <input>) has an attribute called "onblur" whose value is a function. Thus, you can call it. You're not telling the browser to simulate the actual "blur" event, however; there's no event object created, for example.

Elements do not have a "blur" attribute (or "method" or whatever), so that's why the first thing doesn't work.

Please see the following link - here is where I found a solution that worked for me.

Rendering problems in Android Studio v 1.1 / 1.2

Changing the Android Version when rendering layouts worked for me - I flipped it back to 21 and my "Hello World" app then rendered the basic activity_main.xml OK - at 22 I got this error. I borrowed the image from this posting to show you where to click in the Design tab of the XML preview. What is wierd is that when I flip back to 22 the problem is still gone :-).

Dispose() calls the code below, which closes the connections opened by the HttpClient instance. The code was created by decompiling with dotPeek.

HttpClientHandler.cs - Dispose

ServicePointManager.CloseConnectionGroups(this.connectionGroupName);

If you don't call dispose then ServicePointManager.MaxServicePointIdleTime, which runs by a timer, will close the http connections. The default is 100 seconds.

ServicePointManager.cs

internal static readonly TimerThread.Callback s_IdleServicePointTimeoutDelegate = new TimerThread.Callback(ServicePointManager.IdleServicePointTimeoutCallback);
private static volatile TimerThread.Queue s_ServicePointIdlingQueue = TimerThread.GetOrCreateQueue(100000);

private static void IdleServicePointTimeoutCallback(TimerThread.Timer timer, int timeNoticed, object context)
{
  ServicePoint servicePoint = (ServicePoint) context;
  if (Logging.On)
    Logging.PrintInfo(Logging.Web, SR.GetString("net_log_closed_idle", (object) "ServicePoint", (object) servicePoint.GetHashCode()));
  lock (ServicePointManager.s_ServicePointTable)
    ServicePointManager.s_ServicePointTable.Remove((object) servicePoint.LookupString);
  servicePoint.ReleaseAllConnectionGroups();
}

If you haven't set the idle time to infinite then it appears safe not to call dispose and let the idle connection timer kick-in and close the connections for you, although it would be better for you to call dispose in a using statement if you know you are done with an HttpClient instance and free up the resources faster.

Try this code. This seems working in my case.

$this->db->where(array('id !='=> $id))

I found this thread looking for information about dealing with parameters; this easy guide was so cool:

import argparse

parser = argparse.ArgumentParser(description='Script so useful.')
parser.add_argument("--opt1", type=int, default=1)
parser.add_argument("--opt2")

args = parser.parse_args()

opt1_value = args.opt1
opt2_value = args.opt2

run like:

python myScript.py --opt2 = 'hi'

I'm presuming you're using Java 6 and that the ResultSet that you're using is a java.sql.ResultSet.

The JavaDoc for the ResultSet.next() method states:

Moves the cursor froward one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

When a call to the next method returns false, the cursor is positioned after the last row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown.

So, if(rs.next(){ //do something } means "If the result set still has results, move to the next result and do something".

As BalusC pointed out, you need to replace

ResultSet rs = stmt.executeQuery(sql);

with

ResultSet rs = stmt.executeQuery();

Because you've already set the SQL to use in the statement with your previous line

PreparedStatement stmt = conn.prepareStatement(sql);

If you weren't using the PreparedStatement, then ResultSet rs = stmt.executeQuery(sql); would work.

TryGetValue will already assign the default value for the type to the dictionary, so you can just use:

dictionary.TryGetValue(key, out value);

and just ignore the return value. However, that really will just return default(TValue), not some custom default value (nor, more usefully, the result of executing a delegate). There's nothing more powerful built into the framework. I would suggest two extension methods:

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary, 
     TKey key,
     TValue defaultValue)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value : defaultValue;
}

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary,
     TKey key,
     Func<TValue> defaultValueProvider)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value
         : defaultValueProvider();
}

(You may want to put argument checking in, of course :)

shape is a tuple that gives dimensions of the array..

>>> c = arange(20).reshape(5,4)
>>> c
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11],
       [12, 13, 14, 15],
       [16, 17, 18, 19]])

c.shape[0] 
5

Gives the number of rows

c.shape[1] 
4

Gives number of columns

Well, your code worked for me (running Chrome 5.0.307.9 and Firefox 3.5.8 on Ubuntu 9.10), though I switched

to

The loop is great; it's what's inside the loop that's wrong. You need a variable named sum, and at each step, add i+1 to sum. At the end of the loop, sum will have the right value, so print it.

Haskell uses init to refer to all but the last element of a list (the inverse of tail, basically); would isInInit work, or is that too opaque?

A better solution for this is to

1. Copy/past code of Stored Procedure
2. Join that code with the table for which you want to run it again (for each row)

This was you get a clean table-formatted output. While if you run SP for every row, you get a separate query result for each iteration which is ugly.

You should use the fuser command.

Eg. fuser /dev/cdrom will return the pid(s) of the process using /dev/cdrom.

If you are trying to unmount, you can kill theses process using the -k switch (see man fuser).

At least on text inputs, it appears that onChange is listening for input events:

var event = new Event('input', { bubbles: true });
element.dispatchEvent(event);

This solution is not good every time. But i have only two columns and I want second column to take all the remaining space. This worked for me

 <tr>
    <td class="text-nowrap">A</td>
    <td class="w-100">B</td>
 </tr>

If you are using RC5 then import this:

import { CommonModule } from '@angular/common';  
import { BrowserModule } from '@angular/platform-browser';

and be sure to import CommonModule from the module that is providing your component.

 @NgModule({
    imports: [CommonModule],
    declarations: [MyComponent]
  ...
})
class MyComponentModule {}

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

I'm guessing that you're doing some sort of localization, so have a look at this script.

This works for me:

In link, to attribute has value:

to="/filter/arr?fruits=apple&fruits=banana"

Route can handle this:

path="/filter/:arr"

For Multiple arrays:

to="filter/arr?fruits=apple&fruits=banana&vegetables=potato&vegetables=onion"

Route stays same.

This will limit it to however many lines you want it limited to and is responsive

An idea that nobody has suggested, doing it based on the height of the element and then stripping it back from there.

Fiddle - https://jsfiddle.net/hutber/u5mtLznf/ <- ES6 version

But basically you want to grab the line height of the element, loop through all the text and stop when its at a certain lines height:

'use strict';

var linesElement = 3; //it will truncate at 3 lines.
var truncateElement = document.getElementById('truncateme');
var truncateText = truncateElement.textContent;

var getLineHeight = function getLineHeight(element) {
  var lineHeight = window.getComputedStyle(truncateElement)['line-height'];
  if (lineHeight === 'normal') {
    // sucky chrome
    return 1.16 * parseFloat(window.getComputedStyle(truncateElement)['font-size']);
  } else {
    return parseFloat(lineHeight);
  }
};

linesElement.addEventListener('change', function () {
  truncateElement.innerHTML = truncateText;
  var truncateTextParts = truncateText.split(' ');
  var lineHeight = getLineHeight(truncateElement);
  var lines = parseInt(linesElement.value);

  while (lines * lineHeight < truncateElement.clientHeight) {
    console.log(truncateTextParts.length, lines * lineHeight, truncateElement.clientHeight);
    truncateTextParts.pop();
    truncateElement.innerHTML = truncateTextParts.join(' ') + '...';
  }
});

CSS

#truncateme {
   width: auto; This will be completely dynamic to the height of the element, its just restricted by how many lines you want it to clip to
}

Using Flexbox in my solution I've used the justify-content property for the parent element (container) and I've specified the margins inside the flex-basis property of the items. Check the code snippet below:

.container {_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
  justify-content: space-around;_x000D_
  margin-bottom: 10px;_x000D_
}_x000D_
_x000D_
.item {_x000D_
  height: 50px;_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  background-color: #999;_x000D_
}_x000D_
_x000D_
.item-1-4 {_x000D_
  flex-basis: calc(25% - 10px);_x000D_
}_x000D_
_x000D_
.item-1-3 {_x000D_
  flex-basis: calc(33.33333% - 10px);_x000D_
}_x000D_
_x000D_
.item-1-2 {_x000D_
  flex-basis: calc(50% - 10px);_x000D_
}

<div class="container">_x000D_
  <div class="item item-1-4">1</div>_x000D_
  <div class="item item-1-4">2</div>_x000D_
  <div class="item item-1-4">3</div>_x000D_
  <div class="item item-1-4">4</div>_x000D_

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.

Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here

Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html

declare
  x number;
begin
  x := myfunc(myargs);
end;

Alternatively:

select myfunc(myargs) from dual;

I would iterate through the collection detaching everything before deleting the object itself.

here's an example:

try {
        $user = User::findOrFail($id);
        if ($user->has('photos')) {
            foreach ($user->photos as $photo) {

                $user->photos()->detach($photo);
            }
        }
        $user->delete();
        return 'User deleted';
    } catch (Exception $e) {
        dd($e);
    }

I know it is not automatic but it is very simple.

Another simple approach would be to provide the model with a method. Like this:

public function detach(){
       try {
            
            if ($this->has('photos')) {
                foreach ($this->photos as $photo) {
    
                    $this->photos()->detach($photo);
                }
            }
           
        } catch (Exception $e) {
            dd($e);
        }
}

Then you can simply call this where you need:

$user->detach();
$user->delete();

Here is a first try that's easy on the coder but hard on the CPU which prepends a random number to each line, sorts them and then strips the random number from each line. In effect, the lines are sorted randomly:

cat myfile | awk 'BEGIN{srand();}{print rand()"\t"$0}' | sort -k1 -n | cut -f2- > myfile.shuffled

You'll have to pass your arguments as reference types.

#First create the variables (note you have to set them to something)
$global:var1 = $null
$global:var2 = $null
$global:var3 = $null

#The type of the reference argument should be of type [REF]
function foo ($a, $b, [REF]$c)
{
    # add $a and $b and set the requested global variable to equal to it
    # Note how you modify the value.
    $c.Value = $a + $b
}

#You can then call it like this:
foo 1 2 [REF]$global:var3

I upgraded from 2010 to 2013 and after changing all the projects' Platform Toolset, I need to right-click on the Solution and choose Retarget... to make it work.

There are two different ways to implement inserting data from one table to another table.

For Existing Table - INSERT INTO SELECT

This method is used when the table is already created in the database earlier and the data is to be inserted into this table from another table. If columns listed in insert clause and select clause are same, they are not required to list them. It is good practice to always list them for readability and scalability purpose.

----Create testable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
----INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

For Non-Existing Table - SELECT INTO

This method is used when the table is not created earlier and needs to be created when data from one table is to be inserted into the newly created table from another table. The new table is created with the same data types as selected columns.

----Create a new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

They're simply different schemes for representing Unicode characters.

Both are variable-length - UTF-16 uses 2 bytes for all characters in the basic multilingual plane (BMP) which contains most characters in common use.

UTF-8 uses between 1 and 3 bytes for characters in the BMP, up to 4 for characters in the current Unicode range of U+0000 to U+1FFFFF, and is extensible up to U+7FFFFFFF if that ever becomes necessary... but notably all ASCII characters are represented in a single byte each.

For the purposes of a message digest it won't matter which of these you pick, so long as everyone who tries to recreate the digest uses the same option.

See this page for more about UTF-8 and Unicode.

(Note that all Java characters are UTF-16 code points within the BMP; to represent characters above U+FFFF you need to use surrogate pairs in Java.)

Given

l1 = [a,b]
l2 = [b,a]

In Python >= 3.0

assertCountEqual(l1, l2) # True

In Python >= 2.7, the above function was named:

assertItemsEqual(l1, l2) # True

In Python < 2.7

import unittest2
assertItemsEqual(l1, l2) # True

Via six module (Any Python version)

import unittest
import six
class MyTest(unittest.TestCase):
    def test(self):
        six.assertCountEqual(self, self.l1, self.l2) # True

You need to identify the primary key in TableA in order to delete the correct record. The primary key may be a single column or a combination of several columns that uniquely identifies a row in the table. If there is no primary key, then the ROWID pseudo column may be used as the primary key.

DELETE FROM tableA
WHERE ROWID IN 
  ( SELECT q.ROWID
    FROM tableA q
      INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
    WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')
      AND (u.FldFormat = 'Date'));

you need only set default value to parameters(you do not need the Route attribute):

public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

We experienced this with SQL Server 2012 / SP3, when running a query via an SqlCommand object from within a C# application. The Command was a simple invocation of a stored procedure having one table parameter; we were passing a list of about 300 integers. The procedure in turn called three user-defined functions and passed the table as a parameter to each of them. The CommandTimeout was set to 90 seconds.

When running precisely the same stored proc with the same argument from within SQL Server Management Studio, the query ran in 15 seconds. But when running it from our application using the above setup, the SqlCommand timed out. The same SqlCommand (with different but comparable data) had been running successfully for weeks, but now it failed with any table argument containing more than 20 or so integers. We did a trace and discovered that when run from the SqlCommand object, the database spent the entire 90 seconds acquiring locks, and would invoke the procedure only at about the moment of the timeout. We changed the CommandTimeout time, and no matter time what we selected the stored proc would be invoked only at the very end of that period. So we surmise that SQL Server was indefinitely acquiring the same locks over and over, and that only the timeout of the Command object caused SQL Server to stop its infinite loop and begin executing the query, by which time it was too late to succeed. A simulation of this same process on a similar server using similar data exhibited no such problem. Our solution was to reboot the entire database server, after which the problem disappeared.

So it appears that there is some problem in SQL Server wherein some resource gets cumulatively consumed and never released. Eventually when connecting via an SqlConnection and running an SqlCommand involving a table parameter, SQL Server goes into an infinite loop acquiring locks. The loop is terminated by the timeout of the SqlCommand object. The solution is to reboot, apparently restoring (temporary?) sanity to SQL Server.

If the problem is that you are not seeing your changes to the file take effect, just open a new terminal window, and it will be "sourced". You will be able to use the proper PATH etc with each subsequent terminal window.

The following line will start reading a number (%d) followed by anything different from tabs or newlines (%[^\t\n]).

sscanf("19 cool kid", "%d %[^\t\n]", &age, buffer);

Breakpoint :-

breakpoint will stop executing, and let you examine JavaScript values.

After examining values, you can resume the execution of code (typically with a play button).

Debugger :-

The debugger; stops the execution of JavaScript, and callsthe debugging function.

The debugger statement suspends execution, but it does not close any files or clear any variables.

Example:-
function checkBuggyStuff() {
  debugger; // do buggy stuff to examine.
};

one of the easy way to do that is use landa function without any problem like

userControl_Material1.simpleButton4.Click += (s, ee) =>
            {
                Save_mat(mat_global);
            };

Use dict.setdefault():

dic.setdefault(key,[]).append(value)

help(dict.setdefault):

    setdefault(...)
        D.setdefault(k[,d]) -> D.get(k,d), also set D[k]=d if k not in D

As far as I know, by using only Docker this is not possible. You need some DNS to map container ip:s to hostnames.

If you want out of the box solution. One solution is to use for example Kontena. It comes with network overlay technology from Weave and this technology is used to create virtual private LAN networks for each service and every service can be reached by service_name.kontena.local-address.

Here is simple example of Wordpress application's YAML file where Wordpress service connects to MySQL server with wordpress-mysql.kontena.local address:

wordpress:

  image: mariadb:5.5                                                               
  stateful: true

If anyone else gets here because they're trying to set up a Jenkins slave, then you need to set the url of the host to the one it's actually using.

On the host, go to Manage Jenkins > Configure System and edit "Jenkins URL"

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

For integer types, you can do

a ^= b;
b ^= a;
a ^= b;

using the bit-wise xor operator ^. As all the other suggestions, you probably shouldn't use it in production code.

For a reason I don't know, the single line version a ^= b ^= a ^= b doesn't work (maybe my Java compiler has a bug). The single line worked in C with all compilers I tried. However, two-line versions work:

a ^= b ^= a;
b ^= a;

as well as

b ^= a;
a ^= b ^= a;

A proof that it works: Let a0 and b0 be the initial values for a and b. After the first line, a is a1 = a0 xor b0; after the second line, b is b1 = b0 xor a1 = b0 xor (a0 xor b0) = a0. After the third line, a is a2 = a1 xor b1 = a1 xor (b0 xor a1) = b0.

No that is wrong. Arrays are special objects in Java. So it is like passing other objects where you pass the value of the reference, but not the reference itself. Meaning, changing the reference of an array in the called routine will not be reflected in the calling routine.

I solved this issue after changing the "Gradle Version" and "Android Plugin version".

You just goto "File>>Project Structure>>Project>>" and make changes here. I have worked a combination of versions from another working project of mine and added to the Project where I was getting this problem.

Another simple solution is to define your onClickListener, in the getView(..) method, of your ListAdapter.

public View getView(final int position, View convertView, ViewGroup parent){
    //initialise your view
    ...
    View row = context.getLayoutInflater().inflate(R.layout.list_item, null);
    ...

    //define your listener on inner items

    //define your global listener
    row.setOnClickListener(new OnClickListener(){
        public void onClick(View v) {
            doSomethingWithViewAndPosition(v,position);
        }
    });

    return row;

That way your row are clickable, and your inner view too :)

While you haven't provided enough information to actually indicate WHERE you should be pulling data from, you do need to pull it from somewhere. You can specify the URL in load, as well as define data parameters or a callback function.

$("#getCameraSerialNumbers").click(function () {
    $("#step1Content").load('YourUrl');
});

http://api.jquery.com/load/

Every browser has some default styles that apply to a number of HTML elements, likes p and ul. The space you mention is likely created because of the default margin and padding of your browser. You can reset these though:

p { margin: 0; padding: 0; }
ul { margin: 0; padding: 0; }

You could also reset all default margins and paddings:

* { margin: 0; padding: 0; }

I suggest you take a look at normalize.css: http://necolas.github.com/normalize.css/

You can't svn:ignore a file that is already commited to repository.

So you must:

1. Delete the file from the repository.
2. Update your project (the working copy) to the head revision.
3. Recreate the file in Eclipse.
4. Set svn:ignore on the file via Team->Add to svn:ignore.
5. Restart eclipse to reflect changes.

Good luck!

Both the match() (returns the first appearance) and %in% (returns a Boolean) functions are designed for this.

v <- c('a','b','c','e')

'b' %in% v
## returns TRUE

match('b',v)
## returns the first location of 'b', in this case: 2

json_decode() will return an object or array if second value it's true:

$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];

CssRewriteUrlTransform fixed my problem.
If your code still not loading images after using CssRewriteUrlTransform, then change your css filename's from:

.Include("~/Content/jquery/jquery-ui-1.10.3.custom.css", new CssRewriteUrlTransform())

To:

.Include("~/Content/jquery/jquery-ui.css", new CssRewriteUrlTransform())

Someway .(dots) are not recognizing in url.

If textColorSecondary does not work for you, you might have defined colorControlNormal in your theme to be a different color. If so, just use

<style name="yourStyle" parent="Base.Theme.AppCompat">
    <item name="colorAccent">your_color</item> <!-- for checked state -->
    <item name="colorControlNormal">your color</item> <!-- for unchecked state -->
</style>

You have various possibilies. The most simple and the most ugly is:

XAML

<Button Name="cmdCommand" Click="Button_Clicked" Content="Command"/> 

Code Behind

private void Button_Clicked(object sender, RoutedEventArgs e) { 
    FrameworkElement fe=sender as FrameworkElement;
    ((YourClass)fe.DataContext).DoYourCommand();     
} 

Another solution (better) is to provide a ICommand-property on your YourClass. This command will have already a reference to your YourClass-object and therefore can execute an action on this class.

XAML

<Button Name="cmdCommand" Command="{Binding YourICommandReturningProperty}" Content="Command"/>

Because during writing this answer, a lot of other answers were posted, I stop writing more. If you are interested in one of the ways I showed or if you think I have made a mistake, make a comment.

Why do you not use the java functionality for that:

If your numbers are small (smaller than yours) you could use: Integer.parseInt(hex, 16) to convert a Hex - String into an integer.

  String hex = "ff"
  int value = Integer.parseInt(hex, 16);  

For big numbers like yours, use public BigInteger(String val, int radix)

  BigInteger value = new BigInteger(hex, 16);

@See JavaDoc:

• Integer.parseInt(String value, int radix)
• BigInteger(String value, int radix)

Intro

As of the time of writing, the original answer is now 8 years old. Still I feel like there isn't yet a proper solution to the original question.

Bootstrap has gone a long way since then and is now at 4.5.2. This answer addresses this very version.

The problem with all other solutions so far

The issue with all the other answers is, that while they hook into show.bs.dropdown / hide.bs.dropdown, the follow-up events shown.bs.dropdown / hidden.bs.dropdown are either fired too early (animation still ongoing) or they don't fire at all because they were suppressed (e.preventDefault()).

A clean solution

Since the implementation of show() and hide() in Bootstraps Dropdown class share some similarities, I've grouped them together in toggleDropdownWithAnimation() when mimicing the original behaviour and added little QoL helper functions to showDropdownWithAnimation() and hideDropdownWithAnimation().
toggleDropdownWithAnimation() creates a shown.bs.dropdown / hidden.bs.dropdown event the same way Bootstrap does it. This event is then fired after the animation completed - just like you would expect.

/**
 * Toggle visibility of a dropdown with slideDown / slideUp animation.
 * @param {JQuery} $containerElement The outer dropdown container. This is the element with the .dropdown class.
 * @param {boolean} show Show (true) or hide (false) the dropdown menu.
 * @param {number} duration Duration of the animation in milliseconds
 */
function toggleDropdownWithAnimation($containerElement, show, duration = 300): void {
    // get the element that triggered the initial event
    const $toggleElement = $containerElement.find('.dropdown-toggle');
    // get the associated menu
    const $dropdownMenu = $containerElement.find('.dropdown-menu');
    // build jquery event for when the element has been completely shown
    const eventArgs = {relatedTarget: $toggleElement};
    const eventType = show ? 'shown' : 'hidden';
    const eventName = `${eventType}.bs.dropdown`;
    const jQueryEvent = $.Event(eventName, eventArgs);

    if (show) {
        // mimic bootstraps element manipulation
        $containerElement.addClass('show');
        $dropdownMenu.addClass('show');
        $toggleElement.attr('aria-expanded', 'true');
        // put focus on initial trigger element
        $toggleElement.trigger('focus');
        // start intended animation
        $dropdownMenu
            .stop() // stop any ongoing animation
            .hide() // hide element to fix initial state of element for slide down animation
            .slideDown(duration, () => {
            // fire 'shown' event
            $($toggleElement).trigger(jQueryEvent);
        });
    }
    else {
        // mimic bootstraps element manipulation
        $containerElement.removeClass('show');
        $dropdownMenu.removeClass('show');
        $toggleElement.attr('aria-expanded', 'false');
        // start intended animation
        $dropdownMenu
            .stop() // stop any ongoing animation
            .show() // show element to fix initial state of element for slide up animation
            .slideUp(duration, () => {

            // fire 'hidden' event
            $($toggleElement).trigger(jQueryEvent);
        });
    }
}

/**
 * Show a dropdown with slideDown animation.
 * @param {JQuery} $containerElement The outer dropdown container. This is the element with the .dropdown class.
 * @param {number} duration Duration of the animation in milliseconds
 */
function showDropdownWithAnimation($containerElement, duration = 300) {
    toggleDropdownWithAnimation($containerElement, true, duration);
}

/**
 * Hide a dropdown with a slideUp animation.
 * @param {JQuery} $containerElement The outer dropdown container. This is the element with the .dropdown class.
 * @param {number} duration Duration of the animation in milliseconds
 */
function hideDropdownWithAnimation($containerElement, duration = 300) {
    toggleDropdownWithAnimation($containerElement, false, duration);
}

Bind Event Listeners

Now that we have written proper callbacks for showing / hiding a dropdown with an animation, let's actually bind these to the correct events.

A common mistake I've seen a lot in other answers is binding event listeners to elements directly. While this works fine for DOM elements present at the time the event listener is registered, it does not bind to elements added later on.

That's why you are generally better off binding directly to the document:

$(function () {

    /* Hook into the show event of a bootstrap dropdown */
    $(document).on('show.bs.dropdown', '.dropdown', function (e) {
        // prevent bootstrap from executing their event listener
        e.preventDefault();
        
        showDropdownWithAnimation($(this));
    });

    /* Hook into the hide event of a bootstrap dropdown */
    $(document).on('hide.bs.dropdown', '.dropdown', function (e) {
        // prevent bootstrap from executing their event listener
        e.preventDefault();
          
        hideDropdownWithAnimation($(this));
    });

});

With regards to small teams using Dropbox:

If each developer has their own writable bare repository on Dropbox, which is pull only to other developers, then this facilitates code sharing with no risk of corruption!

Then if you want a centralized 'mainline', you can have one developer manage all the pushes to it from their own repo.

If you are creating a code library, then I would use namespace. However, you can still only have one Color enum inside that namespace. If you need an enum that might use a common name, but might have different constants for different classes, use your approach.

The Sean's solution didn't work for me initially (Android 4.2.2). I had to add a dummy activity to the same Android project and run the activity manually on the device at least once. Then the Sean's solution started to work and the BroadcastReceiver was notified after subsequent reboots.

In case you don't want (or have) a running container, you can call your script directly with the run command.

Remove the iterative tty -i -t arguments and use this:

    $ docker run ubuntu:bionic /bin/bash /path/to/script.sh

This will (didn't test) also work for other scripts:

    $ docker run ubuntu:bionic /usr/bin/python /path/to/script.py

The communication link between the driver and the data source to which the driver was attempting to connect failed before the function completed processing. So usually its a network error. This could be caused by packet drops or badly configured Firewall/Switch.

While there are many ways to skin this cat, I prefer to wrap such code into reusable extension methods that make it trivial to do going forward. When using extension methods, you can also avoid RegEx as it is slower than a direct character check. I like using the extensions in the Extensions.cs NuGet package. It makes this check as simple as:

1. Add the https://www.nuget.org/packages/Extensions.cs package to your project.
2. Add "using Extensions;" to the top of your code.
3. "smith23".IsAlphabetic() will return False whereas "john smith".IsAlphabetic() will return True. By default the .IsAlphabetic() method ignores spaces, but it can also be overridden such that "john smith".IsAlphabetic(false) will return False since the space is not considered part of the alphabet.
4. Every other check in the rest of the code is simply MyString.IsAlphabetic().

I don't know whether there's a better answer out there as time goes by but this is simple and it works;

input[type='email'] {
  background: white url(images/mail.svg) no-repeat ;
}
input[type='email']:focus {
  background-image: none;
}

Style it up to suit.

if( obj[0] )

a cleaner version of this might be:

if( typeof Object.keys(obj)[0] === 'undefined' )

where the result will be undefined if no object property is set.

I used Mike Hansen's solution, it is great. I modified his solution in one point, instead of replacing parts of the string I modified the XML-attribute. Maybe it is too much of an effort when you can modify the string but anyway, here is my solution for that. This could easily be further modified to change the table etc. too, which is very nice imho.

What was helpful for me was a helper sub to write the XML to a file so I could check the structure and content of it:

Sub writeStringToFile(strPath As String, strText As String)
    '#### writes a given string into a given filePath, overwriting a document if it already exists
        Dim objStream
        
        Set objStream = CreateObject("ADODB.Stream")
        objStream.Charset = "utf-8"
        objStream.Open
        objStream.WriteText strText
        objStream.SaveToFile strPath, 2
    End Sub

The XML of an/my ImportExportSpecification for a table with 2 columns looks like this:

<?xml version="1.0"?>
<ImportExportSpecification Path="mypath\mydocument.xlsx" xmlns="urn:www.microsoft.com/office/access/imexspec">
    <ImportExcel FirstRowHasNames="true" AppendToTable="myTableName" Range="myExcelWorksheetName">
        <Columns PrimaryKey="{Auto}">
            <Column Name="Col1" FieldName="SomeFieldName" Indexed="NO" SkipColumn="false" DataType="Double"/>
            <Column Name="Col2" FieldName="SomeFieldName" Indexed="NO" SkipColumn="false" DataType="Text"/>
        </Columns>
    </ImportExcel>
</ImportExportSpecification>

Then I wrote a function to modify the path. I left out error-handling here:

Function modifyDataSourcePath(strNewPath As String, strXMLSpec As String) As String
'#### Changes the path-name of an import-export specification
    Dim xDoc As MSXML2.DOMDocument60
    Dim childNodes As IXMLDOMNodeList
    Dim nodeImExSpec As MSXML2.IXMLDOMNode
    Dim childNode As MSXML2.IXMLDOMNode
    Dim attributesImExSpec As IXMLDOMNamedNodeMap
    Dim attributeImExSpec As IXMLDOMAttribute

    
    Set xDoc = New MSXML2.DOMDocument60
    xDoc.async = False: xDoc.validateOnParse = False
    xDoc.LoadXML (strXMLSpec)
    Set childNodes = xDoc.childNodes
 
    For Each childNode In childNodes
           If childNode.nodeName = "ImportExportSpecification" Then
                Set nodeImExSpec = childNode
                Exit For
            End If
    Next childNode
    
    Set attributesImExSpec = nodeImExSpec.Attributes
    
    For Each attributeImExSpec In attributesImExSpec
        If attributeImExSpec.nodeName = "Path" Then
            attributeImExSpec.Value = strNewPath
            Exit For
        End If
    Next attributeImExSpec
    
    modifyDataSourcePath = xDoc.XML
End Function

I use this in Mike's code before the newSpec is executed and instead of the replace statement. Also I write the XML-string into an XML-file in a location relative to the database but that line is optional:

Set myNewSpec = CurrentProject.ImportExportSpecifications.item("TemporaryImport")
    myNewSpec.XML = modifyDataSourcePath(myPath, myNewSpec.XML)
    Call writeStringToFile(Application.CurrentProject.Path & "\impExpSpec.xml", myNewSpec.XML)
    myNewSpec.Execute

It's working..

The MySQL extension is the oldest of the three and was the original way that developers used to communicate with MySQL. This extension is now being deprecated in favor of the other two alternatives because of improvements made in newer releases of both PHP and MySQL.

• MySQLi is the 'improved' extension for working with MySQL databases. It takes advantage of features that are available in newer versions of the MySQL server, exposes both a function-oriented and an object-oriented interface to the developer and a does few other nifty things.

• PDO offers an API that consolidates most of the functionality that was previously spread across the major database access extensions, i.e. MySQL, PostgreSQL, SQLite, MSSQL, etc. The interface exposes high-level objects for the programmer to work with database connections, queries and result sets, and low-level drivers perform communication and resource handling with the database server. A lot of discussion and work is going into PDO and it’s considered the appropriate method of working with databases in modern, professional code.

I fixed it adding these lines in the build.grandle (App Module)

dependencies {
   compile fileTree(dir: 'libs', include: ['*.jar']) //it was there
   compile "com.android.support:support-v4:21.0.+" //Added
   compile "com.android.support:appcompat-v7:21.0.+" //Added
}

Have a look at Schema and Data Comparison tools in dbForge Studio for MySQL. These tool will help you to compare, to see the differences, generate a synchronization script and synchronize two databases.

here is my custom function

function reverse_substring(str,from,to){
  var temp="";
  var i=0;
  var pos = 0;
  var append;      
  for(i=str.length-1;i>=0;i--){
    //alert("inside loop " + str[i]);
    if(pos == from){
         append=true;
    }

    if(pos == to){
         append=false;
         break;
    }
    if(append){
         temp = str[i] + temp;
    }
    pos++;
  }
  alert("bottom loop " + temp);
}

var str = "bala_123";
reverse_substring(str,0,3);

This function works for reverse index.

From a quick search, Oracle appears to use double quotes (", eg "table") and apparently requires the correct case—whereas, for anyone interested, MySQL defaults to using backticks (`) except when set to use double quotes for compatibility.

I've found this script example useful (from http://www.mrexcel.com/forum/excel-questions/898899-json-api-excel.html#post4332075 ):

if you have Firebug installed on Firefox, just open the url. In the network panel, right-click and select Copy as cURL. You can see all curl parameters for this web call.

That simply means using Linux, Apache, MySQL and PHP as your operating system, web server, database, and programming language, respectively.

You are not the first one to think about a "revision number" in Git, but 'wc' is quite dangerous, since commit can be erased or squashed, and the history revisited.

The "revision number" was especially important for Subversion since it was needed in case of merge (SVN1.5 and 1.6 have improved on that front).

You could end up with a pre-commit hook which would include a revision number in the comment, with an algorithm not involving looking up the all history of a branch to determine the correct number.

Bazaar actually came up with such an algorithm , and it may be a good starting point for what you want to do.

(As Bombe's answer points out, Git has actually an algorithm of its own, based on the latest tag, plus the number of commits, plus a bit of an SHA-1 key). You should see (and upvote) his answer if it works for you.

To illustrate Aaron's idea, you can also append the Git commit hash into an application’s "info" file you are distributing with your application.

That way, the about box would look like:

The applicative number is part of the commit, but the 'application’s "info" file' is generated during the packaging process, effectively linking an applicative build number to a technical revision id.

You should check out heroku_san, it solves this problem quite nicely.

For example, you could:

git checkout BRANCH
rake qa deploy

It also makes it easy to spin up new Heroku instances to deploy a topic branch to new servers:

git checkout BRANCH
# edit config/heroku.yml with new app instance and shortname
rake shortname heroku:create deploy # auto creates deploys and migrates

And of course you can make simpler rake tasks if you do something frequently.

You can’t. One reason is that not every web site uses PHP. And another reason is: Even if there are some signs that PHP might be used (e.g. .php file name extension, some “PHPSESSID” parameter, X-Powered-By header field containing “PHP”, etc.) those information might be spoofed to let you think PHP is used.

Minimal example varying azim, dist and elev

To add some simple sample images to what was explained at: https://stackoverflow.com/a/12905458/895245

Here is my test program:

#!/usr/bin/env python3

import sys

import matplotlib.pyplot as plt
from matplotlib import cm
from matplotlib.ticker import LinearLocator, FormatStrFormatter
import numpy as np

fig = plt.figure()
ax = fig.gca(projection='3d')

if len(sys.argv) > 1:
    azim = int(sys.argv[1])
else:
    azim = None
if len(sys.argv) > 2:
    dist = int(sys.argv[2])
else:
    dist = None
if len(sys.argv) > 3:
    elev = int(sys.argv[3])
else:
    elev = None

# Make data.
X = np.arange(-5, 6, 1)
Y = np.arange(-5, 6, 1)
X, Y = np.meshgrid(X, Y)
Z = X**2

# Plot the surface.
surf = ax.plot_surface(X, Y, Z, linewidth=0, antialiased=False)

# Labels.
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlabel('z')

if azim is not None:
    ax.azim = azim
if dist is not None:
    ax.dist = dist
if elev is not None:
    ax.elev = elev

print('ax.azim = {}'.format(ax.azim))
print('ax.dist = {}'.format(ax.dist))
print('ax.elev = {}'.format(ax.elev))

plt.savefig(
    'main_{}_{}_{}.png'.format(ax.azim, ax.dist, ax.elev),
    format='png',
    bbox_inches='tight'
)

Running it without arguments gives the default values:

ax.azim = -60
ax.dist = 10
ax.elev = 30

Vary azim

The azimuth is the rotation around the z axis e.g.:

• 0 means "looking from +x"
• 90 means "looking from +y"

main_0_10_30.png

Vary dist

dist seems to be the distance from the center visible point in data coordinates.

main_-60_5_30.png

main_-60_20_-30.png

Vary elev

From this we understand that elev is the angle between the eye and the xy plane.

Tested on matpotlib==3.2.2.

A small drawback in Marc's answer is that both datefields have been typecast, meaning you'll be unable to leverage any indexes.

So, if there is a need to write a query that can benefit from an index on a date field, then the following (rather convoluted) approach is necessary.

• The indexed datefield (call it DF1) must be untouched by any kind of function.
• So you have to compare DF1 to the full range of datetime values for the day of DF2.
• That is from the date-part of DF2, to the date-part of the day after DF2.
• I.e. (DF1 >= CAST(DF2 AS DATE)) AND (DF1 < DATEADD(dd, 1, CAST(DF2 AS DATE)))
• NOTE: It is very important that the comparison is >= (equality allowed) to the date of DF2, and (strictly) < the day after DF2. Also the BETWEEN operator doesn't work because it permits equality on both sides.

PS: Another means of extracting the date only (in older versions of SQL Server) is to use a trick of how the date is represented internally.

• Cast the date as a float.
• Truncate the fractional part
• Cast the value back to a datetime
• I.e. CAST(FLOOR(CAST(DF2 AS FLOAT)) AS DATETIME)

With Enzyme 3, if you need to change an input value but don't need to fire the onChange function you can just do this (node property has been removed):

wrapper.find('input').instance().value = "foo";

You can use wrapper.find('input').simulate("change", { target: { value: "foo" }}) to invoke onChange if you have a prop for that (ie, for controlled components).

Here is something I think will work for what you want, using a decorator.

class LogWrappedFunction(object):
    def __init__(self, function):
        self.function = function

    def logAndCall(self, *arguments, **namedArguments):
        print "Calling %s with arguments %s and named arguments %s" %\
                      (self.function.func_name, arguments, namedArguments)
        self.function.__call__(*arguments, **namedArguments)

def logwrap(function):
    return LogWrappedFunction(function).logAndCall

@logwrap
def doSomething(spam, eggs, foo, bar):
    print "Doing something totally awesome with %s and %s." % (spam, eggs)


doSomething("beans","rice", foo="wiggity", bar="wack")

Run it, it will yield the following output:

C:\scripts>python decoratorExample.py
Calling doSomething with arguments ('beans', 'rice') and named arguments {'foo':
 'wiggity', 'bar': 'wack'}
Doing something totally awesome with beans and rice.

Sometimes sorting the whole data ahead is very time consuming. We can groupby first and doing topk for each group:

g = df.groupby(['id']).apply(lambda x: x.nlargest(topk,['value'])).reset_index(drop=True)

Better to just use .addClass() and .removeClass() even if you have 1 or more styles to change. It's more maintainable and readable.

If you really have the urge to do multiple CSS properties, then use the following:

.css({
   'font-size' : '10px',
   'width' : '30px',
   'height' : '10px'
});

NB!
Any CSS properties with a hyphen need to be quoted.
I've placed the quotes so no one will need to clarify that, and the code will be 100% functional.

As defined in the link below, you can delete in a straight forward manner

USE AdventureWorks2008R2;
GO
DELETE TOP (20) 
FROM Purchasing.PurchaseOrderDetail
WHERE DueDate < '20020701';
GO

AngularJS – Isolated Scopes – @ vs = vs &

Short examples with explanation are available at below link :

http://www.codeforeach.com/angularjs/angularjs-isolated-scopes-vs-vs

@ – one way binding

In directive:

scope : { nameValue : "@name" }

In view:

<my-widget name="{{nameFromParentScope}}"></my-widget>

= – two way binding

In directive:

scope : { nameValue : "=name" },
link : function(scope) {
  scope.name = "Changing the value here will get reflected in parent scope value";
}

In view:

<my-widget name="{{nameFromParentScope}}"></my-widget>

& – Function call

In directive :

scope : { nameChange : "&" }
link : function(scope) {
  scope.nameChange({newName:"NameFromIsolaltedScope"});
}

In view:

<my-widget nameChange="onNameChange(newName)"></my-widget>

Nothing to worry it's easy

If you are using any local server like Wamp, Xampp then Go to this Steps

1. Go to your drive
2. Check xampp or wamp server that you installed
3. Inside that check php, if you got then go for next step

4. You will find php.exe, Once you get php.exe then you are done. Just type the path like below, here i am using XAMPP and type v for checking version and you are done.

   C:>"C:\xampp\php\php.exe" -v

Thanks.

Another option would be to add engine='python' to the command pandas.read_csv(filename, sep='\t', engine='python')

You can do it using the aggregation pipeline, but it's a pain to write it yourself.

You can use mongo-join-query to create the aggregation pipeline automatically from your query.

This is how your query would look like:

const mongoose = require("mongoose");
const joinQuery = require("mongo-join-query");

joinQuery(
    mongoose.models.Comment,
    {
        find: { pid:444 },
        populate: ["uid"]
    },
    (err, res) => (err ? console.log("Error:", err) : console.log("Success:", res.results))
);

Your result would have the user object in the uid field and you can link as many levels deep as you want. You can populate the reference to the user, which makes reference to a Team, which makes reference to something else, etc..

Disclaimer: I wrote mongo-join-query to tackle this exact problem.

Combining other answers, why not use the ms timestamp with a random value appended; repeat until no conflict, which in practice will be almost never.
