Another option is winsw: https://github.com/kohsuke/winsw/

Configure an xml file to specify the service name, what to execute, any arguments etc. And use the exe to install. Example xml: https://github.com/kohsuke/winsw/tree/master/examples

I prefer this to nssm, because it is one lightweight exe; and the config xml is easy to share/commit to source code.

PS the service is installed by running your-service.exe install

Comparing two predominant answers

(x%m + m)%m;

and

int r = x%m;
return r<0 ? r+m : r;

Nobody actually mentioned the fact that the first one may throw an OverflowException while the second one won't. Even worse, with default unchecked context, the first answer may return the wrong answer (see mod(int.MaxValue - 1, int.MaxValue) for example). So the second answer not only seems to be faster, but also more correct.

Here is a real world example which shows front/mid/back end.

General description:

• Frontend is responsible for presenting data to user. Please note interesting quirk that you may have two different front ends associated with single backend
• Backend provides business logic/data persistence.
• Middleware (activemq in the picture) is responsible for system to system. integration between backends. Usually it is installed as separate application

Overlapping:

It is possible to have overlapping between frontend and backend. This usually leaads to long-term issues with application maintenance and scalability. Fairly common in legacy applications.

Most modern technology stacks encourage developers to have strict separation. For example in the picture you can see that backend of the first system has rest web service which is a clear separation line.

Bottlenecks

Most bottlenecks in large are caused by database/network. Databases are located in backend. As for network issues every connection goes through netowrk, so every connection has potential for being slow. With good application design these issues are avoidable to large extend.

from the sourcecode at http://mozilla.github.com/pdf.js/build/pdf.js

/**
 * This is the main entry point for loading a PDF and interacting with it.
 * NOTE: If a URL is used to fetch the PDF data a standard XMLHttpRequest(XHR)
 * is used, which means it must follow the same origin rules that any XHR does
 * e.g. No cross domain requests without CORS.
 *
 * @param {string|TypedAray|object} source Can be an url to where a PDF is
 * located, a typed array (Uint8Array) already populated with data or
 * and parameter object with the following possible fields:
 *  - url   - The URL of the PDF.
 *  - data  - A typed array with PDF data.
 *  - httpHeaders - Basic authentication headers.
 *  - password - For decrypting password-protected PDFs.
 *
 * @return {Promise} A promise that is resolved with {PDFDocumentProxy} object.
 */

So a standard XMLHttpRequest(XHR) is used for retrieving the document. The Problem with this is that XMLHttpRequests do not support data: uris (eg. data:application/pdf;base64,JVBERi0xLjUK...).

But there is the possibility of passing a typed Javascript Array to the function. The only thing you need to do is to convert the base64 string to a Uint8Array. You can use this function found at https://gist.github.com/1032746

var BASE64_MARKER = ';base64,';

function convertDataURIToBinary(dataURI) {
  var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
  var base64 = dataURI.substring(base64Index);
  var raw = window.atob(base64);
  var rawLength = raw.length;
  var array = new Uint8Array(new ArrayBuffer(rawLength));

  for(var i = 0; i < rawLength; i++) {
    array[i] = raw.charCodeAt(i);
  }
  return array;
}

tl;dr

var pdfAsDataUri = "data:application/pdf;base64,JVBERi0xLjUK..."; // shortened
var pdfAsArray = convertDataURIToBinary(pdfAsDataUri);
PDFJS.getDocument(pdfAsArray)

Scenario

In a college there are many students doing different courses, and after an examination we have to prepare a marks card showing grade. I can calculate grade two ways

1. I can write some code like this

    if(totalMark <= 100 && totalMark > 90) { grade = "A+"; }
    else if(totalMark <= 90 && totalMark > 80) { grade = "A"; }
    else if(totalMark <= 80 && totalMark > 70) { grade = "B"; }
    else if(totalMark <= 70 && totalMark > 60) { grade = "C"; }

2. You can ask user to enter grade definition some where and save that data

Something like storing into a database table

In the first case the grade is common for all the courses and if the rule changes the code needs to be changed. But for second case we are giving user the provision to enter grade based on their requirement. So the code will be not be changed when the grade rules changes.

That's the important thing when you give more provision for users to define business logic. The first case is nothing but Hard Coding.

So in your question if you ask the user to enter the path of the file at the start, then you can remove the hard coded path in your code.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

When I looked at the solutions in the other answers I saw some things that I know are bad for performance. I was going to put them in a comment but I thought it was better to benchmark it and share the results. You can test it yourself. Below are my results (ymmv) normalized after the fastest operation in each browser (multiply the 1.0 time with the normalized value to get the absolute time in ms).

Test where performed on Windows 7 32bit with the folowing versions: Chrome 21.0.1180.89m, Firefox 15.0, Opera 12.02, MSIE 9.0.8112, Safari 5.1.7. Node was run on a Linux 64bit box because the timer resolution on Node.js for Windows was 10ms instead of 1ms.

if-immediate

This is the fastest in all tested environments, except in ... drumroll MSIE! (surprise, surprise). This is the recommended way to implement it.

if (val < 1000) { /*do something */ } else
if (val < 2000) { /*do something */ } else
...
if (val < 30000) { /*do something */ } else

if-indirect

This is a variant of switch-indirect-array but with if-statements instead and performs much faster than switch-indirect-array in almost all tested environments.

values=[
   1000,  2000, ... 30000
];
if (val < values[0]) { /* do something */ } else
if (val < values[1]) { /* do something */ } else
...
if (val < values[29]) { /* do something */ } else

switch-immediate

This is pretty fast in all tested environments, and actually the fastest in MSIE. It works when you can do a calculation to get an index.

switch (Math.floor(val/1000)) {
  case 0: /* do something */ break;
  case 1: /* do something */ break;
  ...
  case 29: /* do something */ break;
}

switch-range

This is about 6 to 40 times slower than the fastest in all tested environments except for Opera where it takes about one and a half times as long. It is slow because the engine has to compare the value twice for each case. Surprisingly it takes Chrome almost 40 times longer to complete this compared to the fastest operation in Chrome, while MSIE only takes 6 times as long. But the actual time difference was only 74ms in favor to MSIE at 1337ms(!).

switch (true) {
  case (0 <= val &&  val < 1000): /* do something */ break;
  case (1000 <= val &&  val < 2000): /* do something */ break;
  ...
  case (29000 <= val &&  val < 30000): /* do something */ break;
}

switch-range2

This is a variant of switch-range but with only one compare per case and therefore faster, but still very slow except in Opera. The order of the case statement is important since the engine will test each case in source code order ECMAScript262:5 12.11

switch (true) {
  case (val < 1000): /* do something */ break;
  case (val < 2000): /* do something */ break;
  ...
  case (val < 30000): /* do something */ break;
}

switch-indirect-array

In this variant the ranges is stored in an array. This is slow in all tested environments and very slow in Chrome.

values=[1000,  2000 ... 29000, 30000];

switch(true) {
  case (val < values[0]): /* do something */ break;
  case (val < values[1]): /* do something */ break;
  ...
  case (val < values[29]): /* do something */ break;
}

array-linear-search

This is a combination of a linear search of values in an array, and the switch statement with fixed values. The reason one might want to use this is when the values isn't known until runtime. It is slow in every tested environment, and takes almost 10 times as long in MSIE.

values=[1000,  2000 ... 29000, 30000];

for (sidx=0, slen=values.length; sidx < slen; ++sidx) {
  if (val < values[sidx]) break;
}

switch (sidx) {
  case 0: /* do something */ break;
  case 1: /* do something */ break;
  ...
  case 29: /* do something */ break;
}

array-binary-switch

This is a variant of array-linear-switch but with a binary search. Unfortunately it is slower than the linear search. I don't know if it is my implementation or if the linear search is more optimized. It could also be that the keyspace is to small.

values=[0, 1000,  2000 ... 29000, 30000];

while(range) {
  range = Math.floor( (smax - smin) / 2 );
  sidx = smin + range;
  if ( val < values[sidx] ) { smax = sidx; } else { smin = sidx; }
}

switch (sidx) {
  case 0: /* do something */ break;
  ...
  case 29: /* do something */ break;
}

Conclusion

If performance is important, use if-statements or switch with immediate values.

Before dealing with the iterables and iterator the major factor that decide the iterable and iterator is sequence

Sequence: Sequence is the collection of data

Iterable: Iterable are the sequence type object that support __iter__ method.

Iter method: Iter method take sequence as an input and create an object which is known as iterator

Iterator: Iterator are the object which call next method and transverse through the sequence. On calling the next method it returns the object that it traversed currently.

example:

x=[1,2,3,4]

x is a sequence which consists of collection of data

y=iter(x)

On calling iter(x) it returns a iterator only when the x object has iter method otherwise it raise an exception.If it returns iterator then y is assign like this:

y=[1,2,3,4]

As y is a iterator hence it support next() method

On calling next method it returns the individual elements of the list one by one.

After returning the last element of the sequence if we again call the next method it raise an StopIteration error

example:

>>> y.next()
1
>>> y.next()
2
>>> y.next()
3
>>> y.next()
4
>>> y.next()
StopIteration

Supposing the list may be long and the numbers may repeat, consider using the SortedList type from the Python sortedcontainers module. The SortedList type will automatically maintain the tuples in order by number and allow for fast searching.

For example:

from sortedcontainers import SortedList
sl = SortedList([(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")])

# Get the index of 53:

index = sl.bisect((53,))

# With the index, get the tuple:

tup = sl[index]

This will work a lot faster than the list comprehension suggestion by doing a binary search. The dictionary suggestion will be faster still but won't work if there could be duplicate numbers with different strings.

If there are duplicate numbers with different strings then you need to take one more step:

end = sl.bisect((53 + 1,))

results = sl[index:end]

By bisecting for 54, we will find the end index for our slice. This will be significantly faster on long lists as compared with the accepted answer.

I newer version of xampp you may use another method first open your httpd-xampp.conf file and find the string "phpmyadmin" using ctrl+F command (Windows). and then replace this code

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

with this

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

Don't Forget to Restart your Xampp.

I highly recommend looking into this plugin:

http://github.com/evanplaice/jquery-csv/

I used this for a project handling large CSV files and it handles parsing a CSV into an array quite well. You can use this to call a local file that you specify in your code, also, so you are not dependent on a file upload.

Once you include the plugin above, you can essentially parse the CSV using the following:

$.ajax({
    url: "pathto/filename.csv",
    async: false,
    success: function (csvd) {
        data = $.csv.toArrays(csvd);
    },
    dataType: "text",
    complete: function () {
        // call a function on complete 
    }
});

Everything will then live in the array data for you to manipulate as you need. I can provide further examples for handling the array data if you need.

There are a lot of great examples available on the plugin page to do a variety of things, too.

One candidate key is chosen as the primary key. Other candidate keys are called alternate keys.

It is in fact NTFS permissions, and a strange bug in SQL Server. I'm not sure the above bug report is accurate, or may refer to an additional bug.

To resolve this on Windows 7, I ran SQL Server Management Studio normally (not as Administrator). I then attempted to Attach the MDF file. In the process, I used the UI rather than pasting in the path. I noticed that the path was cut off from me. This is because the MS SQL Server (SQLServerMSSQLUser$machinename$SQLEXPRESS) user that the software adds for you does not have permissions to access the folder (in this case a folder deep in my own user folders).

Pasting the path and proceeding results in the above error. So - I gave the MS SQL Server user permissions to read starting from the first directory it was denied from (my user folder). I then immediately cancelled the propagation operation because it can take an eternity, and again applied read permissions to the next subfolder necessary, and let that propagate fully.

Finally, I gave the MS SQL Server user Modify permissions to the .mdf and .ldf files for the db.

I can now Attach to the database files.

None of the above worked for me because my devices are in a balance-rr bond. Querying either would say the same MAC address with ip l l, ifconfig, or /sys/class/net/${device}/address, so one of them is correct, and one is unknown.

But this works if you haven't renamed the device (any tips on what I missed?):

udevadm info -q all --path "/sys/class/net/${device}"

And this works even if you rename it (eg. ip l set name x0 dev p4p1):

cat /proc/net/bonding/bond0

or my ugly script that makes it more parsable (untested driver/os/whatever compatibility):

awk -F ': ' '
         $0 == "" && interface != "" {
            printf "%s %s %s\n", interface, mac, status;
            interface="";
            mac=""
         }; 
         $1 == "Slave Interface" {
            interface=$2
         }; 
         $1 == "Permanent HW addr" {
            mac=$2
         };
         $1 == "MII Status" {
            status=$2
         };
         END {
            printf "%s %s %s\n", interface, mac, status
         }' /proc/net/bonding/bond0

You can do this with css transforms, though be careful with container height/width. Also you may need to position it lower:

input[type="range"] {_x000D_
   position: absolute;_x000D_
   top: 40%;_x000D_
   transform: rotate(270deg);_x000D_
}

<input type="range"/>

or the 3d transform equivalent:

input[type="range"] {
   transform: rotateZ(270deg);
}

You can also use this to switch the direction of the slide by setting it to 180deg or 90deg for horizontal or vertical respectively.

I strongly recommend using lowercase field|column names, it will make your life easier.

Let's assume you have a table called users with the following definition and records:

id|firstname|lastname|username             |password
1 |joe      |doe     |[email protected]   |1234
2 |jane     |doe     |[email protected]  |12345
3 |johnny   |doe     |[email protected]|123456

let's say you want to get all records from table users, then you do:

SELECT * FROM users;

Now let's assume you want to select all records from table users, but you're interested only in the fields id, firstname and lastname, thus ignoring username and password:

SELECT id, firstname, lastname FROM users;

Now we get at the point where you want to retrieve records based on condition(s), what you need to do is to add the WHERE clause, let's say we want to select from users only those that have username = [email protected] and password = 1234, what you do is:

SELECT * FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );

But what if you need only the id of a record with username = [email protected] and password = 1234? then you do:

SELECT id FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );

Now to get to your question, as others before me answered you can use the IN clause:

SELECT * FROM users
WHERE ( id IN (1,2,..,n) );

or, if you wish to limit to a list of records between id 20 and id 40, then you can easily write:

SELECT * FROM users
WHERE ( ( id >= 20 ) AND ( id <= 40 ) );

I hope this gives a better understanding.

In my case, it's related to the Toggle Vrapper Icon in the Eclipse.

If you are getting the bold black cursor, then the icon must be enabled. So, click on the Toggle Vrapper Icon to disable. It's located in the Eclipse's Toolbar. Please see the attached image for the clarity.

Using swing you could simply use a JLabel

 public static void main(String[] args) throws MalformedURLException {

        URL url = new URL("<URL to your Animated GIF>");
        Icon icon = new ImageIcon(url);
        JLabel label = new JLabel(icon);

        JFrame f = new JFrame("Animation");
        f.getContentPane().add(label);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

About efficiency and concernig time spent on allocation, I made this simple test below, I created many instances through these two ways (one at a time):

for (int k = 0 ; k < 30000000; ++k)
{
    // took more time than using new
    std::shared_ptr<int> foo = std::make_shared<int> (10);

    // was faster than using make_shared
    std::shared_ptr<int> foo2 = std::shared_ptr<int>(new int(10));
}

The thing is, using make_shared took the double time compared with using new. So, using new there are two heap allocations instead of one using make_shared. Maybe this is a stupid test but doesn't it show that using make_shared takes more time than using new? Of course, I'm talking about time used only.

Generalizing Afanasii Kurakin's answer, we have:

function replaceAt(str, index, ch) {
    return str.replace(/./g, (c, i) => i == index ? ch : c);
}

let str = 'Hello World';
str = replaceAt(str, 1, 'u');
console.log(str); // Hullo World

Let's expand and explain both the regular expression and the replacer function:

function replaceAt(str, index, newChar) {
    function replacer(origChar, strIndex) {
        if (strIndex === index)
            return newChar;
        else
            return origChar;
    }
    return str.replace(/./g, replacer);
}

let str = 'Hello World';
str = replaceAt(str, 1, 'u');
console.log(str); // Hullo World

The regular expression . matches exactly one character. The g makes it match every character in a for loop. The replacer function is called given both the original character and the index of where that character is in the string. We make a simple if statement to determine if we're going to return either origChar or newChar.

To see where the data directory is, use this query.

show data_directory;

To see all the run-time parameters, use

show all;

You can create tablespaces to store database objects in other parts of the filesystem. To see tablespaces, which might not be in that data directory, use this query.

SELECT * FROM pg_tablespace;

'dsn' => 'mysql:host=localhost;port=3307;dbname=yourdbname',

No. It's per command, not per connection.

Edit, May 2013

As requested in comment:

• SQLCommand.CommandTimeout for command execution
• There is no matching SQLConnection property (the questions says not the SqlConnection.ConnectionTimeout property

Some more notes about commands and execution time outs in SQL Server (DBA.SE). And more SO stuff: What happens to an uncommitted transaction when the connection is closed?

A couple of scenarios might help illustrate the purpose of access and refresh tokens and the engineering trade-offs in designing an oauth2 (or any other auth) system:

Web app scenario

In the web app scenario you have a couple of options:

1. if you have your own session management, store both the access_token and refresh_token against your session id in session state on your session state service. When a page is requested by the user that requires you to access the resource use the access_token and if the access_token has expired use the refresh_token to get the new one.

Let's imagine that someone manages to hijack your session. The only thing that is possible is to request your pages.

2. if you don't have session management, put the access_token in a cookie and use that as a session. Then, whenever the user requests pages from your web server send up the access_token. Your app server could refresh the access_token if need be.

Comparing 1 and 2:

In 1, access_token and refresh_token only travel over the wire on the way between the authorzation server (google in your case) and your app server. This would be done on a secure channel. A hacker could hijack the session but they would only be able to interact with your web app. In 2, the hacker could take the access_token away and form their own requests to the resources that the user has granted access to. Even if the hacker gets a hold of the access_token they will only have a short window in which they can access the resources.

Either way the refresh_token and clientid/secret are only known to the server making it impossible from the web browser to obtain long term access.

Let's imagine you are implementing oauth2 and set a long timeout on the access token:

In 1) There's not much difference here between a short and long access token since it's hidden in the app server. In 2) someone could get the access_token in the browser and then use it to directly access the user's resources for a long time.

Mobile scenario

On the mobile, there are a couple of scenarios that I know of:

1. Store clientid/secret on the device and have the device orchestrate obtaining access to the user's resources.

2. Use a backend app server to hold the clientid/secret and have it do the orchestration. Use the access_token as a kind of session key and pass it between the client and the app server.

Comparing 1 and 2

In 1) Once you have clientid/secret on the device they aren't secret any more. Anyone can decompile and then start acting as though they are you, with the permission of the user of course. The access_token and refresh_token are also in memory and could be accessed on a compromised device which means someone could act as your app without the user giving their credentials. In this scenario the length of the access_token makes no difference to the hackability since refresh_token is in the same place as access_token. In 2) the clientid/secret nor the refresh token are compromised. Here the length of the access_token expiry determines how long a hacker could access the users resources, should they get hold of it.

Expiry lengths

Here it depends upon what you're securing with your auth system as to how long your access_token expiry should be. If it's something particularly valuable to the user it should be short. Something less valuable, it can be longer.

Some people like google don't expire the refresh_token. Some like stackflow do. The decision on the expiry is a trade-off between user ease and security. The length of the refresh token is related to the user return length, i.e. set the refresh to how often the user returns to your app. If the refresh token doesn't expire the only way they are revoked is with an explicit revoke. Normally, a log on wouldn't revoke.

Hope that rather length post is useful.

Use css to add a right margin to those particular elements. Generally I would build the control, then run it to see what the resulting html structure is like, then make the css alter just those elements.

Preferably you do this by setting the class. Add the CssClass="myrblclass" attribute to your list declaration.

You can also add attributes to the items programmatically, which will come out the other side.

rblMyRadioButtonList.Items[x].Attributes.CssStyle.Add("margin-right:5px;")

This may be better for you since you can add that attribute for all but the last one.

this should work:

private void cleanlistbox(object sender, EventArgs e)
{
    listBox1.Items.Clear( );
}

& is always evaluated in a string context, while + may not concatenate if one of the operands is no string:

"1" + "2" => "12"
"1" + 2   => 3
1 + "2"   => 3
"a" + 2   => type mismatch

This is simply a subtle source of potential bugs and therefore should be avoided. & always means "string concatenation", even if its arguments are non-strings:

"1" & "2" => "12"
"1" &  2  => "12"
 1  & "2" => "12"
 1  &  2  => "12"
"a" &  2  => "a2"

I don't know a single-function method for this, but you can use genpath to recurse a list of subdirectories only. This list is returned as a semicolon-delimited string of directories, so you'll have to separate it using strread, i.e.

dirlist = strread(genpath('/path/of/directory'),'%s','delimiter',';')

If you don't want to include the given directory, remove the first entry of dirlist, i.e. dirlist(1)=[]; since it is always the first entry.

Then get the list of files in each directory with a looped dir.

filenamelist=[];
for d=1:length(dirlist)
    % keep only filenames
    filelist=dir(dirlist{d});
    filelist={filelist.name};

    % remove '.' and '..' entries
    filelist([strmatch('.',filelist,'exact');strmatch('..',filelist,'exact'))=[];
    % or to ignore all hidden files, use filelist(strmatch('.',filelist))=[];

    % prepend directory name to each filename entry, separated by filesep*
    for f=1:length(filelist)
        filelist{f}=[dirlist{d} filesep filelist{f}];
    end

    filenamelist=[filenamelist filelist];
end

filesep returns the directory separator for the platform on which MATLAB is running.

This gives you a list of filenames with full paths in the cell array filenamelist. Not the neatest solution, I know.

You can try this..

class SampleClass(forms.Form):
  name = forms.CharField(max_length=30)
  name.widget.attrs.update({'class': 'your-class'})
...

You can see more information in: Django Widgets

var filename=location.href.substr(location.href.lastIndexOf("/")+1);
alert(filename);

try this css:

/* Show in default resolution screen*/
#container2 {
width: 960px;
position: relative;
margin:0 auto;
line-height: 1.4em;
}

/* If in mobile screen with maximum width 479px. The iPhone screen resolution is 320x480 px (except iPhone4, 640x960) */    
@media only screen and (max-width: 479px){
    #container2 { width: 90%; }
}

• Go to the Application pools in the IIS
• Right click on my project application pool
• In Process Model section open Identity
• Choose Custom account option
• Enter your pc user name and password.

Use ScriptEngine.eval(java.io.Reader) to read the script

ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
// read script file
engine.eval(Files.newBufferedReader(Paths.get("C:/Scripts/Jsfunctions.js"), StandardCharsets.UTF_8));

Invocable inv = (Invocable) engine;
// call function from script file
inv.invokeFunction("yourFunction", "param");

Offhand, I can't think of a real scenario in which extending Application is either preferable to another approach or necessary to accomplish something. If you have an expensive, frequently used object you can initialize it in an IntentService when you detect that the object isn't currently present. Application itself runs on the UI thread, while IntentService runs on its own thread.

I prefer to pass data from Activity to Activity with explicit Intents, or use SharedPreferences. There are also ways to pass data from a Fragment to its parent Activity using interfaces.

jQuery Ajax loader is not working well when you call two APIs simultaneously. To resolve this problem you have to call the APIs one by one using the isAsync property in Ajax setting. You also need to make sure that there should not be any error in the setting. Otherwise, the loader will not work. E.g undefined content-type, data-type for POST/PUT/DELETE/GET call.

$myArr = array();

function someFuntion(array $myArr) {
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;

    return $myArr;
}

$myArr = someFunction($myArr);

var date = new Date("2012-01-18T16:03");

console.log( (date.getMinutes()<10?'0':'') + date.getMinutes() );

I was playing with this and came up with an alternative.

$ VAR=/home/me/mydir/file.c

$ DIR=`echo $VAR |xargs dirname`

$ echo $DIR
/home/me/mydir

The part I liked is it was easy to extend backup the tree:

$ DIR=`echo $VAR |xargs dirname |xargs dirname |xargs dirname`

$ echo $DIR
/home

If your action is not idempotent, then you MUST use POST. If you don't, you're just asking for trouble down the line. GET, PUT and DELETE methods are required to be idempotent. Imagine what would happen in your application if the client was pre-fetching every possible GET request for your service – if this would cause side effects visible to the client, then something's wrong.

I agree that sending a POST with a query string but without a body seems odd, but I think it can be appropriate in some situations.

Think of the query part of a URL as a command to the resource to limit the scope of the current request. Typically, query strings are used to sort or filter a GET request (like ?page=1&sort=title) but I suppose it makes sense on a POST to also limit the scope (perhaps like ?action=delete&id=5).

This method is much faster. You can only tel when placing a lot of files in a directory. My A:\ external hard drive contains almost 1 terabit so it makes a big difference when dealing with a lot of files.

static void Main(string[] args)
{
    DirectoryInfo di = new DirectoryInfo("A:\\");
    FullDirList(di, "*");
    Console.WriteLine("Done");
    Console.Read();
}

static List<FileInfo> files = new List<FileInfo>();  // List that will hold the files and subfiles in path
static List<DirectoryInfo> folders = new List<DirectoryInfo>(); // List that hold direcotries that cannot be accessed
static void FullDirList(DirectoryInfo dir, string searchPattern)
{
    // Console.WriteLine("Directory {0}", dir.FullName);
    // list the files
    try
    {
        foreach (FileInfo f in dir.GetFiles(searchPattern))
        {
            //Console.WriteLine("File {0}", f.FullName);
            files.Add(f);                    
        }
    }
    catch
    {
        Console.WriteLine("Directory {0}  \n could not be accessed!!!!", dir.FullName);                
        return;  // We alredy got an error trying to access dir so dont try to access it again
    }

    // process each directory
    // If I have been able to see the files in the directory I should also be able 
    // to look at its directories so I dont think I should place this in a try catch block
    foreach (DirectoryInfo d in dir.GetDirectories())
    {
        folders.Add(d);
        FullDirList(d, searchPattern);                    
    }

}

By the way I got this thanks to your comment Jim Mischel

You need to either provide the absolute path to data.csv, or run your script in the same directory as data.csv.

If you're open to using RoboGuice, you can have the context injected into any class you want. Here's a small sample of how to do it with RoboGuice 2.0 (beta 4 at time of this writing)

import android.content.Context;
import android.os.Build;
import roboguice.inject.ContextSingleton;

import javax.inject.Inject;

@ContextSingleton
public class DataManager {
    @Inject
    public DataManager(Context context) {
            Properties properties = new Properties();
            properties.load(context.getResources().getAssets().open("data.properties"));
        } catch (IOException e) {
        }
    }
}

You can use DSUM, which will be more flexible. Like if you want to change the name of Salesman or the Quote Month, you need not change the formula, but only some criteria cells. Please see the link below for details...Even the criteria can be formula to copied from other sheets

http://office.microsoft.com/en-us/excel-help/dsum-function-HP010342460.aspx?CTT=1

You can make them 1024 x 768. You can also check "Status bar is initially hidden" in the plist file.

I run two instances of visual studio--one for the external dll and one for the main application.
In the project properties of the external dll, set the following:

Build Events:

• copy /y "$(TargetDir)$(TargetName).dll" "C:\<path-to-main> \bin\$(ConfigurationName)\$(TargetName).dll"

• copy /y "$(TargetDir)$(TargetName).pdb" "C:\<path-to-main> \bin\$(ConfigurationName)\$(TargetName).pdb"

Debug:

• Start external program: C:\<path-to-main>\bin\debug\<AppName>.exe

• Working Directory C:\<path-to-main>\bin\debug

This way, whenever I build the external dll, it gets updated in the main application's directory. If I hit debug from the external dll's project--the main application runs, but the debugger only hits breakpoints in the external dll. If I hit debug from the main project, the main application runs with the most recently built external dll, but now the debugger only hits breakpoints in the main project.

I realize one debugger will do the job for both, but I find it easier to keep the two straight this way.

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

Foreign key and check constraints have the concept of being trusted or untrusted, as well as being enabled and disabled. See the MSDN page for ALTER TABLE for full details.

WITH CHECK is the default for adding new foreign key and check constraints, WITH NOCHECK is the default for re-enabling disabled foreign key and check constraints. It's important to be aware of the difference.

Having said that, any apparently redundant statements generated by utilities are simply there for safety and/or ease of coding. Don't worry about them.

In Visual Studio UML sequence this can also be described as fragments which is nicely documented here: https://msdn.microsoft.com/en-us/library/dd465153.aspx

<TextInput autoCapitalize={'none'} maxLength={10} placeholder='Mobile Number'  value={this.state.mobile} onChangeText={(mobile) => this.onChanged(mobile)}/>

and onChanged method :

onChanged(text){
   var newText = '';
   var numbers = '0123456789';
   if(text.length < 1){
     this.setState({ mobile: '' });
   }
   for (var i=0; i < text.length; i++) {
        if(numbers.indexOf(text[i]) > -1 ) {
             newText = newText + text[i];
        }
        this.setState({ mobile: newText });
    }
}

Copied from the stacktrace:

BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib has a constructor with a SessionFactory argument. By adding the @Autowired annotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactory in your case, and provide it as a constructor argument, e.g.

@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
    // ...
}

This is based on the assumption that you're getting an error about the date format, such as an invalid month value or non-numeric character when numeric expected.

Dates stored in the database do not have formats. When you query the date your client is formatting the date for display, as 4/16/2011. Normally the same date format is used for selecting and updating dates, but in this case they appear to be different - so your client is apparently doing something more complicated that SQL*Plus, for example.

When you try to update it it's using a default date format model. Because of how it's displayed you're assuming that is MM/DD/YYYY, but it seems not to be. You could find out what it is, but it's better not to rely on the default or any implicit format models at all.

Whether that is the problem or not, you should always specify the date model:

UPDATE PASOFDATE SET ASOFDATE = TO_DATE('11/21/2012', 'MM/DD/YYYY');

Since you aren't specifying a time component - all Oracle DATE columns include a time, even if it's midnight - you could also use a date literal:

UPDATE PASOFDATE SET ASOFDATE = DATE '2012-11-21';

You should maybe check that the current value doesn't include a time, though the column name suggests it doesn't.

Currently, MySQL doesn't allow to set multiple values in one method call. So you have to have it under your own control. I usually create one prepared statement for predefined number of parameters, then I add as many batches as I need.

    int paramSizeInClause = 10; // required to be greater than 0!
    String color = "FF0000"; // red
    String name = "Nathan"; 
    Date now = new Date();
    String[] ids = "15,21,45,48,77,145,158,321,325,326,327,328,329,330,331,332,333,334,335,336,337,338,339,340,341,342,343,344,345,346,347,348,349,350,351,358,1284,1587".split(",");

    // Build sql query 
    StringBuilder sql = new StringBuilder();
    sql.append("UPDATE book SET color=? update_by=?, update_date=? WHERE book_id in (");
    // number of max params in IN clause can be modified 
    // to get most efficient combination of number of batches
    // and number of parameters in each batch
    for (int n = 0; n < paramSizeInClause; n++) {
        sql.append("?,");
    }
    if (sql.length() > 0) {
        sql.deleteCharAt(sql.lastIndexOf(","));
    }
    sql.append(")");

    PreparedStatement pstm = null;
    try {
        pstm = connection.prepareStatement(sql.toString());
        int totalIdsToProcess = ids.length;
        int batchLoops = totalIdsToProcess / paramSizeInClause + (totalIdsToProcess % paramSizeInClause > 0 ? 1 : 0);
        for (int l = 0; l < batchLoops; l++) {
            int i = 1;
            pstm.setString(i++, color);
            pstm.setString(i++, name);
            pstm.setTimestamp(i++, new Timestamp(now.getTime()));
            for (int count = 0; count < paramSizeInClause; count++) {
                int param = (l * paramSizeInClause + count);
                if (param < totalIdsToProcess) {
                    pstm.setString(i++, ids[param]);
                } else {
                    pstm.setNull(i++, Types.VARCHAR);
                }
            }
            pstm.addBatch();
        }
    } catch (SQLException e) {
    } finally {
        //close statement(s)
    }

If you don't like to set NULL when no more parameters left, you can modify code to build two queries and two prepared statements. First one is the same, but second statement for the remainder (modulus). In this particular example that would be one query for 10 params and one for 8 params. You will have to add 3 batches for the first query (first 30 params) then one batch for the second query (8 params).

Select Replicate('0',2 - DataLength(Convert(VarChar(2),DatePart(DAY, GetDate()))) + Convert(VarChar(2),DatePart(DAY, GetDate())

Usually when you have to start doing this sort of thing in SQL, you need switch from can I, to should I.

The basic idea of static import is that whenever you are using a static class,a static variable or an enum,you can import them and save yourself from some typing.

I will elaborate my point with example.

import java.lang.Math;

class WithoutStaticImports {

 public static void main(String [] args) {
  System.out.println("round " + Math.round(1032.897));
  System.out.println("min " + Math.min(60,102));
 }
}

Same code, with static imports:

import static java.lang.System.out;
import static java.lang.Math.*;

class WithStaticImports {
  public static void main(String [] args) {
    out.println("round " + round(1032.897));
    out.println("min " + min(60,102));
  }
}

Note: static import can make your code confusing to read.

You first have to tell Gnuplot to use a style that uses points, e.g. with points or with linespoints. Try for example:

plot sin(x) with points

Output:

Now try:

plot sin(x) with points pointtype 5

Output:

You may also want to look at the output from the test command which shows you the capabilities of the current terminal. Here are the capabilities for my pngairo terminal:

I am simply using the daemon npm module:

var daemon = require('daemon');

daemon.daemonize({
    stdout: './log.log'
  , stderr: './log.error.log'
  }
, './node.pid'
, function (err, pid) {
  if (err) {
    console.log('Error starting daemon: \n', err);
    return process.exit(-1);
  }
  console.log('Daemonized successfully with pid: ' + pid);

  // Your Application Code goes here
});

Lately I'm also using mon(1) from TJ Holowaychuk to start and manage simple node apps.

What Mocha options are you using?

Maybe it is something to do with reporter (-R) or ui (-ui) being used?

console.log(msg);

works fine during my test runs, though sometimes mixed in a little goofy. Presumably due to the async nature of the test run.

Here are the options (mocha.opts) I'm using:

--require should
-R spec
--ui bdd

Hmm..just tested without any mocha.opts and console.log still works.

I recently stuck in with this error while building my containerized jar applications with Bamboo:

org.apache.maven.surefire.booter.SurefireBooterForkException: The forked VM terminated without properly saying goodbye

After many hours of researching I fixed it. And I thought it would be useful to share my solution here.

So the error happen every time when bamboo run mvn clean package command for java applications in the docker containers. I am no Maven expert but the trouble was in Surefire and Junit4 plugins included in spring-boot as maven dependency.

To fix it you need to replace Junit4 for Junit5 and override Surefire plugin in you pom.xml.

1.Inside spring boot dependency insert exclusion:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <!-- FIX BAMBOO DEPLOY>
    <exclusions>

            <artifactId>junit</artifactId>
        </exclusion>
    </exclusions>
    <!---->
</dependency>

2. Add new Junit5 dependencies:

Many in the community would prefer no limit with warnings about performance, see this comment for a well reasoned argument: https://jira.mongodb.org/browse/SERVER-431?focusedCommentId=22283&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-22283

My take, the lead developers are stubborn about this issue because they decided it was an important "feature" early on. They're not going to change it anytime soon because their feelings are hurt that anyone questioned it. Another example of personality and politics detracting from a product in open source communities but this is not really a crippling issue.

As rcar says, you can't without losing some quality, the best you can do in c# is:

Bitmap newImage = new Bitmap(newWidth, newHeight);
using (Graphics gr = Graphics.FromImage(newImage))
{
    gr.SmoothingMode = SmoothingMode.HighQuality;
    gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
    gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
    gr.DrawImage(srcImage, new Rectangle(0, 0, newWidth, newHeight));
}

You can set the default search_path at the database level:

ALTER DATABASE <database_name> SET search_path TO schema1,schema2;

Or at the user or role level:

ALTER ROLE <role_name> SET search_path TO schema1,schema2;

Or if you have a common default schema in all your databases you could set the system-wide default in the config file with the search_path option.

When a database is created it is created by default from a hidden "template" database named template1, you could alter that database to specify a new default search path for all databases created in the future. You could also create another template database and use CREATE DATABASE <database_name> TEMPLATE <template_name> to create your databases.

In response to Jonathan's answer above, this only seems to work for certain delimiters. For example:

>>> a='Beautiful, is; better*than\nugly'
>>> import re
>>> re.split('; |, |\*|\n',a)
['Beautiful', 'is', 'better', 'than', 'ugly']

>>> b='1999-05-03 10:37:00'
>>> re.split('- :', b)
['1999-05-03 10:37:00']

By putting the delimiters in square brackets it seems to work more effectively.

>>> re.split('[- :]', b)
['1999', '05', '03', '10', '37', '00']

This usually happens when you are not in the docker group. You can add yourself to the docker group with:

sudo usermod -aG docker yourusername

or

sudo usermod -aG docker $(whoami)

After this, you need to logout and log back into the server.

Alternatively, you can sudo every Docker command.

set -o xtrace

or

bash -x myscript.sh

This works with standard /bin/sh as well IIRC (it might be a POSIX thing then)

And remember, there is bashdb (bash Shell Debugger, release 4.0-0.4)

To revert to normal, exit the subshell or

set +o xtrace

In java.lang.String, the replace method either takes a pair of char's or a pair of CharSequence's (of which String is a subclass, so it'll happily take a pair of String's). The replace method will replace all occurrences of a char or CharSequence. On the other hand, the first String arguments of replaceFirst and replaceAll are regular expressions (regex). Using the wrong function can lead to subtle bugs.

So this is what I ended up doing

var dateText = moment(someDate).from(new Date());
var startOfToday = moment().startOf('day');
var startOfDate = moment(someDate).startOf('day');
var daysDiff = startOfDate.diff(startOfToday, 'days');
var days = {
  '0': 'today',
  '-1': 'yesterday',
  '1': 'tomorrow'
};

if (Math.abs(daysDiff) <= 1) {
  dateText = days[daysDiff];
}

You can also use this in windows with python 3.6 python -m pip install scipy

Well in order to understand how static and dynamic binding actually works? or how they are identified by compiler and JVM?

Let's take below example where Mammal is a parent class which has a method speak() and Human class extends Mammal, overrides the speak() method and then again overloads it with speak(String language).

public class OverridingInternalExample {

    private static class Mammal {
        public void speak() { System.out.println("ohlllalalalalalaoaoaoa"); }
    }

    private static class Human extends Mammal {

        @Override
        public void speak() { System.out.println("Hello"); }

        // Valid overload of speak
        public void speak(String language) {
            if (language.equals("Hindi")) System.out.println("Namaste");
            else System.out.println("Hello");
        }

        @Override
        public String toString() { return "Human Class"; }

    }

    //  Code below contains the output and bytecode of the method calls
    public static void main(String[] args) {
        Mammal anyMammal = new Mammal();
        anyMammal.speak();  // Output - ohlllalalalalalaoaoaoa
        // 10: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V

        Mammal humanMammal = new Human();
        humanMammal.speak(); // Output - Hello
        // 23: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V

        Human human = new Human();
        human.speak(); // Output - Hello
        // 36: invokevirtual #7 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:()V

        human.speak("Hindi"); // Output - Namaste
        // 42: invokevirtual #9 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:(Ljava/lang/String;)V
    }
}

When we compile the above code and try to look at the bytecode using javap -verbose OverridingInternalExample, we can see that compiler generates a constant table where it assigns integer codes to every method call and byte code for the program which I have extracted and included in the program itself (see the comments below every method call)

By looking at above code we can see that the bytecodes of humanMammal.speak(), human.speak() and human.speak("Hindi") are totally different (invokevirtual #4, invokevirtual #7, invokevirtual #9) because the compiler is able to differentiate between them based on the argument list and class reference. Because all of this get resolved at compile time statically that is why Method Overloading is known as Static Polymorphism or Static Binding.

But bytecode for anyMammal.speak() and humanMammal.speak() is same (invokevirtual #4) because according to compiler both methods are called on Mammal reference.

So now the question comes if both method calls have same bytecode then how does JVM know which method to call?

Well, the answer is hidden in the bytecode itself and it is invokevirtual instruction set. JVM uses the invokevirtual instruction to invoke Java equivalent of the C++ virtual methods. In C++ if we want to override one method in another class we need to declare it as virtual, But in Java, all methods are virtual by default because we can override every method in the child class (except private, final and static methods).

In Java, every reference variable holds two hidden pointers

1. A pointer to a table which again holds methods of the object and a pointer to the Class object. e.g. [speak(), speak(String) Class object]
2. A pointer to the memory allocated on the heap for that object’s data e.g. values of instance variables.

So all object references indirectly hold a reference to a table which holds all the method references of that object. Java has borrowed this concept from C++ and this table is known as virtual table (vtable).

A vtable is an array like structure which holds virtual method names and their references on array indices. JVM creates only one vtable per class when it loads the class into memory.

So whenever JVM encounter with a invokevirtual instruction set, it checks the vtable of that class for the method reference and invokes the specific method which in our case is the method from a object not the reference.

Because all of this get resolved at runtime only and at runtime JVM gets to know which method to invoke, that is why Method Overriding is known as Dynamic Polymorphism or simply Polymorphism or Dynamic Binding.

You can read it more details on my article How Does JVM Handle Method Overloading and Overriding Internally.

This syntax worked for me in MVC 3 with Razor:

@Html.ActionLink("Delete", "DeleteList", "List", new { ID = item.ID, ListID = item.id }, new {@class= "delete"})

I used the answer given by Chase (answered May 11 '11 at 14:21), but I added a bit of code to apply that solution to my particular problem.

I had a frame of rates (user, download) and a frame of totals (user, download) to be merged by user, and I wanted to include every rate, even if there were no corresponding total. However, there could be no missing totals, in which case the selection of rows for replacement of NA by zero would fail.

The first line of code does the merge. The next two lines change the column names in the merged frame. The if statement replaces NA by zero, but only if there are rows with NA.

# merge rates and totals, replacing absent totals by zero
graphdata <- merge(rates, totals, by=c("user"),all.x=T)
colnames(graphdata)[colnames(graphdata)=="download.x"] = "download.rate"
colnames(graphdata)[colnames(graphdata)=="download.y"] = "download.total"
if(any(is.na(graphdata$download.total))) {
    graphdata[is.na(graphdata$download.total),]$download.total <- 0
}

You can just check for null:

if(Request.QueryString["aspxerrorpath"]!=null)
{
   //your code that depends on aspxerrorpath here
}

Arrays.asList(myArray).contains(false)

This is one of the new features of Java 8, part of JDK Enhancement Proposals 122:

Remove the permanent generation from the Hotspot JVM and thus the need to tune the size of the permanent generation.

The list of all the JEPs that will be included in Java 8 can be found on the JDK8 milestones page.

Although you could easily find a tutorial how to handle file uploads with php, and there are functions (manual) to handle CSVs, I will post some code because just a few days ago I worked on a project, including a bit of code you could use...

HTML:

<table width="600">
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" enctype="multipart/form-data">

<tr>
<td width="20%">Select file</td>
<td width="80%"><input type="file" name="file" id="file" /></td>
</tr>

<tr>
<td>Submit</td>
<td><input type="submit" name="submit" /></td>
</tr>

</form>
</table>

PHP:

if ( isset($_POST["submit"]) ) {

   if ( isset($_FILES["file"])) {

            //if there was an error uploading the file
        if ($_FILES["file"]["error"] > 0) {
            echo "Return Code: " . $_FILES["file"]["error"] . "<br />";

        }
        else {
                 //Print file details
             echo "Upload: " . $_FILES["file"]["name"] . "<br />";
             echo "Type: " . $_FILES["file"]["type"] . "<br />";
             echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
             echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

                 //if file already exists
             if (file_exists("upload/" . $_FILES["file"]["name"])) {
            echo $_FILES["file"]["name"] . " already exists. ";
             }
             else {
                    //Store file in directory "upload" with the name of "uploaded_file.txt"
            $storagename = "uploaded_file.txt";
            move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $storagename);
            echo "Stored in: " . "upload/" . $_FILES["file"]["name"] . "<br />";
            }
        }
     } else {
             echo "No file selected <br />";
     }
}

I know there must be an easier way to do this, but I read the CSV file and store the single cells of every record in an two dimensional array.

if ( isset($storagename) && $file = fopen( "upload/" . $storagename , r ) ) {

    echo "File opened.<br />";

    $firstline = fgets ($file, 4096 );
        //Gets the number of fields, in CSV-files the names of the fields are mostly given in the first line
    $num = strlen($firstline) - strlen(str_replace(";", "", $firstline));

        //save the different fields of the firstline in an array called fields
    $fields = array();
    $fields = explode( ";", $firstline, ($num+1) );

    $line = array();
    $i = 0;

        //CSV: one line is one record and the cells/fields are seperated by ";"
        //so $dsatz is an two dimensional array saving the records like this: $dsatz[number of record][number of cell]
    while ( $line[$i] = fgets ($file, 4096) ) {

        $dsatz[$i] = array();
        $dsatz[$i] = explode( ";", $line[$i], ($num+1) );

        $i++;
    }

        echo "<table>";
        echo "<tr>";
    for ( $k = 0; $k != ($num+1); $k++ ) {
        echo "<td>" . $fields[$k] . "</td>";
    }
        echo "</tr>";

    foreach ($dsatz as $key => $number) {
                //new table row for every record
        echo "<tr>";
        foreach ($number as $k => $content) {
                        //new table cell for every field of the record
            echo "<td>" . $content . "</td>";
        }
    }

    echo "</table>";
}

So I hope this will help, it is just a small snippet of code and I have not tested it, because I used it slightly different. The comments should explain everything.

<select id="form-s" multiple="multiple">
    <option selected>city1</option>
    <option selected value="c2">city2</option>
    <option value="c3">city3</option>
</select>   
<select id="aioConceptName">
    <option value="s1" selected >choose io</option>
    <option value="s2">roma </option>
    <option value="s3">totti</option>
</select>
<select id="test">
    <option value="s4">paloma</option>
    <option value="s5" selected >foo</option>
    <option value="s6">bar</option>
</select>
<script>
$('select').change(function() {
    var a=$(':selected').text(); // "city1city2choose iofoo"
    var b=$(':selected').val();  // "city1" - selects just first query !
    //but..
    var c=$(':selected').map(function(){ // ["city1","city2","choose io","foo"]
        return $(this).text();
    }); 
    var d=$(':selected').map(function(){ // ["city1","c2","s1","s5"]
        return $(this).val();
    });
    console.log(a,b,c,d);
});
</script>

In the Oracle RDBMS, it is possible to use a multi-row subquery in the select clause as long as the (sub-)output is encapsulated as a collection. In particular, a multi-row select clause subquery can output each of its rows as an xmlelement that is encapsulated in an xmlforest.

Using the "point" leads to the creation of a folder named "point" (on Ubuntu 16).

tar -tf site1.bz2 -C /var/www/site1/ .

I dealt with this in more detail and prepared an example. Multi-line recording, plus an exception.

tar -tf site1.bz2\
    -C /var/www/site1/ style.css\
    -C /var/www/site1/ index.html\
    -C /var/www/site1/ page2.html\
    -C /var/www/site1/ page3.html\
    --exclude=images/*.zip\
    -C /var/www/site1/ images/
    -C /var/www/site1/ subdir/

Here is a solution using sponge (from the moreutils package):

head -n -1 foo.txt | sponge foo.txt

Summary of solutions:

1. If you want a fast solution for large files, use the efficient tail or dd approach.

2. If you want something easy to extend/tweak and portable, use the redirect and move approach.

3. If you want something easy to extend/tweak, the file is not too large, portability (i.e., depending on moreutils package) is not an issue, and you are a fan of square pants, consider the sponge approach.

A nice benefit of the sponge approach, compared to "redirect and move" approaches, is that sponge preserves file permissions.

Sponge uses considerably more RAM compared to the "redirect and move" approach. This gains a bit of speed (only about 20%), but if you're interested in speed the "efficient tail" and dd approaches are the way to go.

You can use WMI Code creator. I guess you can have a combination of "keys" (processorid,mac and software generated key).

using System.Management;
using System.Windows.Forms;

try
{
     ManagementObjectSearcher searcher = 
         new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Processor"); 

     foreach (ManagementObject queryObj in searcher.Get())
     {
         Console.WriteLine("-----------------------------------");
         Console.WriteLine("Win32_Processor instance");
         Console.WriteLine("-----------------------------------");
         Console.WriteLine("Architecture: {0}", queryObj["Architecture"]);
         Console.WriteLine("Caption: {0}", queryObj["Caption"]);
         Console.WriteLine("Family: {0}", queryObj["Family"]);
         Console.WriteLine("ProcessorId: {0}", queryObj["ProcessorId"]);
     }
}
catch (ManagementException e)
{
    MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}

<div class="d-flex justify-content-end">...</div>
<div class="d-flex justify-content-between">...</div>

The following approach worked for me:

Create a new personal access token in GitHub and configure the connection in IntelliJ as per link: https://www.jetbrains.com/help/idea/github.html

Then, on IntelliJ, Settings-Version Control-Git screen, unclick the "Use credential helper" option.

Then do an restart with cache invalidation (File - Invalidate Caches / Restart - Invalidate and Restart)

The request header contains some POST data. No matter what you do, when you reload the page, the rquest would be sent again.

The simple solution is to redirect to a new (if not the same) page. This pattern is very common in web applications, and is called Post/Redirect/Get. It's typical for all forms to do a POST, then if successful, you should do a redirect.

Try as much as possible to always separate (in different files) your view script (html mostly) from your controller script (business logic and stuff). In this way, you would always post data to a seperate controller script and then redirect back to a view script which when rendered, will contain no POST data in the request header.

The best way to do it without any headache is to use the \tablefootnote command from the tablefootnote package. Add the following to your preamble:

\usepackage{tablefootnote}

It just works without the need of additional tricks.

That is not possible du to the Box Model. However you could use a workaround with css3's border-image, or border-color in general css.

However im unsure whether you may have a problem with resetting. Some browsers do set a margin to html as well. See Eric Meyers Reset CSS for more!

html{margin:0;padding:0;}

See http://angular-ui.github.io/bootstrap/#/collapse

function CollapseDemoCtrl($scope) {
  $scope.isCollapsed = false;
}



<div ng-controller="CollapseDemoCtrl">
    <button class="btn" ng-click="isCollapsed = !isCollapsed">Toggle collapse</button>
    <hr>
    <div collapse="isCollapsed">
        <div class="well well-large">Some content</div> 
    </div>

DateTime is a DataType which is used to store both Date and Time. But it provides Properties to get the Date Part.

You can get the Date part from Date Property.

http://msdn.microsoft.com/en-us/library/system.datetime.date.aspx

DateTime date1 = new DateTime(2008, 6, 1, 7, 47, 0);
Console.WriteLine(date1.ToString());

// Get date-only portion of date, without its time.
DateTime dateOnly = date1.Date;
// Display date using short date string.
Console.WriteLine(dateOnly.ToString("d"));
// Display date using 24-hour clock.
Console.WriteLine(dateOnly.ToString("g"));
Console.WriteLine(dateOnly.ToString("MM/dd/yyyy HH:mm"));   
// The example displays the following output to the console:
//       6/1/2008 7:47:00 AM
//       6/1/2008
//       6/1/2008 12:00 AM
//       06/01/2008 00:00

Swift 3:

extension String {
    func substring(fromPosition: UInt, toPosition: UInt) -> String? {
        guard fromPosition <= toPosition else {
            return nil
        }

        guard toPosition < UInt(characters.count) else {
            return nil
        }

        let start = index(startIndex, offsetBy: String.IndexDistance(fromPosition))
        let end   = index(startIndex, offsetBy: String.IndexDistance(toPosition) + 1)
        let range = start..<end

        return substring(with: range)
    }
}

"ffaabbcc".substring(fromPosition: 2, toPosition: 5) // return "aabb"

Because you also ticked Scala, a solution without regex which easily deals with multiple quoted strings:

val text = "some string with 'the data i want' inside 'and even more data'"
text.split("'").zipWithIndex.filter(_._2 % 2 != 0).map(_._1)

res: Array[java.lang.String] = Array(the data i want, and even more data)

Yes, your example is correct. Anonymous classes can implement interfaces, and that's the only time I can think of that you'll see a class implementing an interface without the "implements" keyword. Check out another code sample right here:

interface ProgrammerInterview {
    public void read();
}

class Website {
    ProgrammerInterview p = new ProgrammerInterview() {
        public void read() {
            System.out.println("interface ProgrammerInterview class implementer");
        }
    };
}

This works fine. Was taken from this page:

http://www.programmerinterview.com/index.php/java-questions/anonymous-class-interface/

In case someone wanted an example using variables...

#!/bin/bash

# Only continue for 'develop' or 'release/*' branches
BRANCH_REGEX="^(develop$|release//*)"

if [[ $BRANCH =~ $BRANCH_REGEX ]];
then
    echo "BRANCH '$BRANCH' matches BRANCH_REGEX '$BRANCH_REGEX'"
else
    echo "BRANCH '$BRANCH' DOES NOT MATCH BRANCH_REGEX '$BRANCH_REGEX'"
fi

This can be done using:

plt.figure(figsize=(15,8))
sns.kdeplot(data,shade=True)

HTTPbis will address the phrasing of 400 Bad Request so that it covers logical errors as well. So 400 will incorporate 422.

From https://tools.ietf.org/html/draft-ietf-httpbis-p2-semantics-18#section-7.4.1
"The server cannot or will not process the request, due to a client error (e.g., malformed syntax)"

Of course it does. After replacing the variable, it reads [ !-z ], which is not a valid [ command. Use double quotes, or [[.

if [ ! -z "$errorstatus" ]

if [[ ! -z $errorstatus ]]

A very simple solution is to search your file(s) for non-ascii characters using a regular expression. This will nicely highlight all the spots where they are found with a border.

Search for [^\x00-\x7F] and check the box for Regex.

The result will look like this (in dark mode):

HTML :

<div id="myDiv">
    <form id="myForm">
    </form> 
</div>

jQuery :

var chbx='<input type="checkbox" id="Mumbai" name="Mumbai" value="Mumbai" />Mumbai<br /> <input type="checkbox" id=" Delhi" name=" Delhi" value=" Delhi" /> Delhi<br/><input type="checkbox" id=" Bangalore" name=" Bangalore" value=" Bangalore"/>Bangalore<br />';

$("#myDiv form#myForm").html(chbx);

//to insert dynamically created form 
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");

cursor.fetchall() and list(cursor) are essentially the same. The different option is to not retrieve a list, and instead just loop over the bare cursor object:

for result in cursor:

This can be more efficient if the result set is large, as it doesn't have to fetch the entire result set and keep it all in memory; it can just incrementally get each item (or batch them in smaller batches).

var xhr = new XMLHttpRequest();
xhr.open('POST', 'somewhere', true);
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.onload = function () {
    // do something to response
    console.log(this.responseText);
};
xhr.send('user=person&pwd=password&organization=place&requiredkey=key');

Or if you can count on browser support you could use FormData:

var data = new FormData();
data.append('user', 'person');
data.append('pwd', 'password');
data.append('organization', 'place');
data.append('requiredkey', 'key');

var xhr = new XMLHttpRequest();
xhr.open('POST', 'somewhere', true);
xhr.onload = function () {
    // do something to response
    console.log(this.responseText);
};
xhr.send(data);

There is a very simple answer to this messy problem--the SUBSTITUTE function. In your example above:

=IF((1/1/INDEX(A,B,C))<>"",(1/1/INDEX(A,B,C)),"")

Can be rewritten as follows:

=SUBSTITUTE((1/1/INDEX(A,B,C), " ", "")

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

If you use the callback URL, then the API can connect to the callback URL and send or receive some data. That means API can connect to you later (after API call).

Example

1. YOU send data using request to API
2. API sends data using second request to YOU

Exact definition should be in API documentation.

Found the code that I referred to in my comment above. To test it, do this:

1. In Sheet1 change the cell height and width of say A1 as shown in the snapshot below.
2. Format the cell by right clicking on it to show time format
3. Add two buttons (form controls) on the worksheet and name them as shown in the snapshot
4. Paste this code in a module
5. Right click on the Start Timer button on the sheet and click on Assign Macros. Select StartTimer macro.
6. Right click on the End Timer button on the sheet and click on Assign Macros. Select EndTimer macro.

Now click on Start Timer button and you will see the time getting updated in cell A1. To stop time updates, Click on End Timer button.

Text wrapping is not part of SVG1.1, the currently implemented spec. You should rather use HTML via the <foreignObject/> element.

<svg ...>

<switch>
<foreignObject x="20" y="90" width="150" height="200">
<p xmlns="http://www.w3.org/1999/xhtml">Text goes here</p>
</foreignObject>

<text x="20" y="20">Your SVG viewer cannot display html.</text>
</switch>

I've long wanted to be able to produce tints/shades of colours, here is my JavaScript solution:

const varyHue = function (hueIn, pcIn) {
    const truncate = function (valIn) {
        if (valIn > 255) {
            valIn = 255;
        } else if (valIn < 0)  {
            valIn = 0;
        }
        return valIn;
    };

    let red   = parseInt(hueIn.substring(0, 2), 16);
    let green = parseInt(hueIn.substring(2, 4), 16);
    let blue  = parseInt(hueIn.substring(4, 6), 16);
    let pc    = parseInt(pcIn, 10);    //shade positive, tint negative
    let max   = 0;
    let dif   = 0;

    max = red;

    if (pc < 0) {    //tint: make lighter
        if (green < max) {
            max = green;
        }

        if (blue < max) {
            max = blue;
        }

        dif = parseInt(((Math.abs(pc) / 100) * (255 - max)), 10);

        return leftPad(((truncate(red + dif)).toString(16)), '0', 2)  + leftPad(((truncate(green + dif)).toString(16)), '0', 2) + leftPad(((truncate(blue + dif)).toString(16)), '0', 2);
    } else {    //shade: make darker
        if (green > max) {
            max = green;
        }

        if (blue > max) {
            max = blue;
        }

        dif = parseInt(((pc / 100) * max), 10);

        return leftPad(((truncate(red - dif)).toString(16)), '0', 2)  + leftPad(((truncate(green - dif)).toString(16)), '0', 2) + leftPad(((truncate(blue - dif)).toString(16)), '0', 2);

There two common way to read file line by line.

1. Use bufio.Scanner
2. Use ReadString/ReadBytes/... in bufio.Reader

In my testcase, ~250MB, ~2,500,000 lines, bufio.Scanner(time used: 0.395491384s) is faster than bufio.Reader.ReadString(time_used: 0.446867622s).

Source code: https://github.com/xpzouying/go-practice/tree/master/read_file_line_by_line

Read file use bufio.Scanner,

func scanFile() {
    f, err := os.OpenFile(logfile, os.O_RDONLY, os.ModePerm)
    if err != nil {
        log.Fatalf("open file error: %v", err)
        return
    }
    defer f.Close()

    sc := bufio.NewScanner(f)
    for sc.Scan() {
        _ = sc.Text()  // GET the line string
    }
    if err := sc.Err(); err != nil {
        log.Fatalf("scan file error: %v", err)
        return
    }
}

Read file use bufio.Reader,

func readFileLines() {
    f, err := os.OpenFile(logfile, os.O_RDONLY, os.ModePerm)
    if err != nil {
        log.Fatalf("open file error: %v", err)
        return
    }
    defer f.Close()

    rd := bufio.NewReader(f)
    for {
        line, err := rd.ReadString('\n')
        if err != nil {
            if err == io.EOF {
                break
            }

            log.Fatalf("read file line error: %v", err)
            return
        }
        _ = line  // GET the line string
    }
}

There is no syntax for block quote in VBA. The work around is to use the button to quickly block or unblock multiple lines of code.

SELECT CONVERT(date, GETDATE())

You can try something like this:

Inside customview constructor:

mContext = context;

Next inside customview you can call:

((MainActivity) mContext).updateText( text );

Inside MainAcivity define:

public void updateText(final String text) {

     TextView txtView = (TextView) findViewById(R.id.text);
     txtView.setText(text);
}

It works for me.

You hide Bootstrap modals with:

$('#modal').modal('hide');

Saying $().hide() makes the matched element invisible, but as far as the modal-related code is concerned, it's still there. See the Methods section in the Modals documentation.

Instead of redis-cli you can simply use nc!

nc -v --ssl redis.mydomain.com 6380

Then submit the commands.

I am not sure if this has to be explicitly enabled anywhere..but for this to work in the first place you need to include the javadoc jar files with the related jars in your project. Then when you do a Cntrl+Space it shows autocomplete and javadocs.

This seems to work:

/descendant::input[@id="search_query"][2]

I go this from "XSLT 2.0 and XPath 2.0 Programmer's Reference, 4th Edition" by Michael Kay.

There is also a note in the "Abbreviated Syntax" section of the XML Path Language specification http://www.w3.org/TR/xpath/#path-abbrev that provided a clue.

Thats work for me:

var jsScripts = [];

jsScripts.push("/js/script1.js" );
jsScripts.push("/js/script2.js" );
jsScripts.push("/js/script3.js" );

$(jsScripts).each(function( index, value ) {
    $.holdReady( true );
    $.getScript( value ).done(function(script, status) {
        console.log('Loaded ' + index + ' : ' + value + ' (' + status + ')');                
        $.holdReady( false );
    });
});

Use -A and -B switches (mean lines-after and lines-before):

grep -A 1 -B 1 FAILED file.txt

This exception will come in case your server is based on JDK 7 and your client is on JDK 6 and using SSL certificates. In JDK 7 sslv2hello message handshaking is disabled by default while in JDK 6 sslv2hello message handshaking is enabled. For this reason when your client trying to connect server then a sslv2hello message will be sent towards server and due to sslv2hello message disable you will get this exception. To solve this either you have to move your client to JDK 7 or you have to use 6u91 version of JDK. But to get this version of JDK you have to get the MOS (My Oracle Support) Enterprise support. This patch is not public.

you are confusing the concept of appending and prepending. the following code is prepending:

sys.path.insert(1,'/thePathToYourFolder/')

it places the new information at the beginning (well, second, to be precise) of the search sequence that your interpreter will go through. sys.path.append() puts things at the very end of the search sequence.

it is advisable that you use something like virtualenv instead of manually coding your package directories into the PYTHONPATH everytime. for setting up various ecosystems that separate your site-packages and possible versions of python, read these two blogs:

1. python ecosystems introduction

2. bootstrapping python virtual environments

if you do decide to move down the path to environment isolation you would certainly benefit by looking into virtualenvwrapper: http://www.doughellmann.com/docs/virtualenvwrapper/

If u want a direct/ quick away, without assing to variables:

{
 urArray.map((prop, key) => {
     console.log(emp);
     return <Picker.Item label={emp.Name} value={emp.id} />;
 })
}

It is a 32bit declaration. If you type at the top of an assembly file the statement [bits 32], then you don't need to type DWORD PTR. So for example:

[bits 32]
.
.
and  [ebp-4], 0

See item 3 in the linked article.

1. Close the solution and the IDE.
2. In Windows Explorer: Change the directory name to the new name.
3. In Windows Explorer: Open the .sln file with a text editor.
4. Change the directory name to the new name and save.
5. Restart the IDE and open the solution from menu File → Recent Files menu if it doesn't start automatically.
6. Click on the project folder in Solution Explorer and check the path property in the properties at the bottom. It will now be referencing to the new project folder.

It worked for me.

The error:

'int' object has no attribute '__getitem__'

means that you're attempting to apply the index operator [] on an int, not a list. So is col not a list, even when it should be? Let's start from that.

Look here:

col = [[0 for col in range(5)] for row in range(6)]

Use a different variable name inside, looks like the list comprehension overwrites the col variable during iteration. (Not during the iteration when you set col, but during the following ones.)

You are most likely seeing the unexpected behavior because your text file was created on Windows, so the end of line sequence is \r\n. You can use dos2unix to convert it to a UNIX style text file before running sed or use

sed -r "/^\r?$/d"

to remove blank lines whether or not the carriage return is there.

Google recommends to use hreflang, read more info

Examples:

<link rel="alternate" href="http://example.com/en-ie" hreflang="en-ie" />
<link rel="alternate" href="http://example.com/en-ca" hreflang="en-ca" />
<link rel="alternate" href="http://example.com/en-au" hreflang="en-au" />
<link rel="alternate" href="http://example.com/en" hreflang="en" />

There is no "one-to-one" mapping between XML and JSON, so converting one to the other necessarily requires some understanding of what you want to do with the results.

That being said, Python's standard library has several modules for parsing XML (including DOM, SAX, and ElementTree). As of Python 2.6, support for converting Python data structures to and from JSON is included in the json module.

So the infrastructure is there.

To insert/append to a dictionary

{"0": {"travelkey":"value", "travelkey2":"value"},"1":{"travelkey":"value","travelkey2":"value"}} 

travel_dict={} #initialize dicitionary 
travel_key=0 #initialize counter

if travel_key not in travel_dict: #for avoiding keyerror 0
    travel_dict[travel_key] = {}
travel_temp={val['key']:'no flexible'}  
travel_dict[travel_key].update(travel_temp) # Updates if val['key'] exists, else adds val['key']
travel_key=travel_key+1

Two things: Change the variables x, y, z as int and call the method as Math.max(Math.max(x,y),z) as it accepts two parameters only.

In Summary, change below:

    String x = keyboard.nextLine();
    String y = keyboard.nextLine();
    String z = keyboard.nextLine();
    int max = Math.max(x,y,z);

to

    int x = keyboard.nextInt();
    int y = keyboard.nextInt();
    int z = keyboard.nextInt();
    int max =  Math.max(Math.max(x,y),z);

Using font-face requires a little understanding of browser inconsistencies and may require some changes on the web server itself. First thing you have to do is check the console to see if/what messages are being generated. Is it a permissions issue or resource not found....?

Secondly because each browser is expecting a different font type I would use Font Squirrel to upload your font and then generate the additional files and CSS needed. http://www.fontsquirrel.com/fontface/generator

And finally, versions of FireFox and IE will not allow fonts to be loaded cross domain. You may need to modify your Apache config or .htaccess (Header set Access-Control-Allow-Origin "*")

Am I missing something?

Yes. ;-)

This phenomenon exists because of the uniform interface constraint. REST likes using already existing standards instead of reinventing the wheel. The HTTP standard has already proven to be highly scalable (the web is working for a while). Why should we fix something which is not broken?!

note: The uniform interface constraint is important if you want to decouple the clients from the service. It is similar to defining interfaces for classes in order to decouple them from each other. Ofc. in here the uniform interface consists of standards like HTTP, MIME types, URI, RDF, linked data vocabs, hydra vocab, etc...

Did you update the project (right-click on the project, "Maven" > "Update project...")? Otherwise, you need to check if pom.xml contains the necessary slf4j dependencies, e.g.:

        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.0</version>

You can disable sql_mode=only_full_group_by by some command you can try this by terminal or MySql IDE

mysql> set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

I have tried this and worked for me. Thanks :)

By simply adding fiddler to the url

http://localhost.fiddler:8081/

Traffic is routed through fiddler and therefore being displayed on fiddler.

Basic syntax is: $(selector).action()

A dollar sign to define jQuery A (selector) to "query (or find)" HTML elements A jQuery action() to be performed on the element(s)

My vote is string.Join

No need for lambda evaluations and temporary functions to be created, fewer function calls, less stack pushing and popping.

While the question has already been answered several times, this simple solution to the problem has not been listed yet.

x = {'a':1, 'b': 2}
y = {'b':10, 'c': 11}
z4 = {}
z4.update(x)
z4.update(y)

It is as fast as z0 and the evil z2 mentioned above, but easy to understand and change.

POST request in itself means sending information in the body. I found a fairly simple way to do this. Use Postman by Google, which allows you to specify the content-type(a header field) as application/json and then provide name-value pairs as parameters. Just use your url in the place of theirs.

POST

var responseString = await "http://www.example.com/recepticle.aspx"
    .PostUrlEncodedAsync(new { thing1 = "hello", thing2 = "world" })
    .ReceiveString();

GET

var responseString = await "http://www.example.com/recepticle.aspx"
    .GetStringAsync();

Almost all Oracle deployments are done through SQL*Plus (that weird little command line tool that your DBA uses). And in SQL*Plus a lone slash basically means "re-execute last SQL or PL/SQL command that I just executed".

See

http://ss64.com/ora/syntax-sqlplus.html

Rule of thumb would be to use slash with things that do BEGIN .. END or where you can use CREATE OR REPLACE.

For inserts that need to be unique use

INSERT INTO my_table ()
SELECT <values to be inserted>
FROM dual
WHERE NOT EXISTS (SELECT 
                  FROM my_table
                  WHERE <identify data that you are trying to insert>)

empty() needs to access the value by reference (in order to check whether that reference points to something that exists), and PHP before 5.5 didn't support references to temporary values returned from functions.

However, the real problem you have is that you use empty() at all, mistakenly believing that "empty" value is any different from "false".

Empty is just an alias for !isset($thing) || !$thing. When the thing you're checking always exists (in PHP results of function calls always exist), the empty() function is nothing but a negation operator.

PHP doesn't have concept of emptyness. Values that evaluate to false are empty, values that evaluate to true are non-empty. It's the same thing. This code:

$x = something();
if (empty($x)) …

and this:

$x = something();
if (!$x) …

has always the same result, in all cases, for all datatypes (because $x is defined empty() is redundant).

Return value from the method always exists (even if you don't have return statement, return value exists and contains null). Therefore:

if (!empty($r->getError()))

is logically equivalent to:

if ($r->getError())

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

for i in 0..max
   puts "Value of local variable is #{i}"
end

All Ruby loops

Eran's answer is good, but I would append to that. You need to watch any interactivity that is not inline to the object (that is, if an onclick event calls a function, it still will), but if there is some javascript or jQuery event handling attached to that ID, it will be basically abandoned:

$("#myId").on("click", function() {});

If the ID is now changed to #myID123, the function attached above will no longer function correctly from my experience.

Thanks for referencing my blog post at http://mbccs.blogspot.com/2007/11/fixing-window-resize-event-in-ie.html.

While you can just hook up to the standard window resize event, you'll find that in IE, the event is fired once for every X and once for every Y axis movement, resulting in a ton of events being fired which might have a performance impact on your site if rendering is an intensive task.

My method involves a short timeout that gets cancelled on subsequent events so that the event doesn't get bubbled up to your code until the user has finished resizing the window.

return (expression) ? value1 : value2;

If value1 and value2 are actually true and false like in your example, you may as well just

return expression;

openssl x509 -outform der -in your-cert.pem -out your-cert.crt

You can also name columns directly in the cbind call, e.g.

cbind(date=c(0,1), high=c(2,3))

Output:

     date high

When you do -

for word in string:

You are not iterating through the words in the string, you are iterating through the characters in the string. To iterate through the words, you would first need to split the string into words , using str.split() , and then iterate through that . Example -

my_string = "this is a string"
for word in my_string.split():
    print (word)

Please note, str.split() , without passing any arguments splits by all whitespaces (space, multiple spaces, tab, newlines, etc).

Add this dependecy in pom.xml file. Hope this help.
In <systemPath> property you have to write your jdk lib path..

    <dependency>  
          <groupId>com.sun</groupId> 
           <artifactId>tools</artifactId>

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

Use Sheets rather than Sheet and activate them sequentially:

Sub kl()
    Dim wb As Workbook
    Dim ws As Worksheet
    Set wb = ActiveWorkbook
    Set ws = Sheets("Sheet1")
    wb.Activate
    ws.Select
End Sub

1. Right click on folder.

2. Click Properties

3. Click Security Tab. You will see something like this:

4. Click "Edit..." button in above screen. You will see something like this:

5. Click "Add..." button in above screen. You will see something like this:

6. Click "Locations..." button in above screen. You will see something like this. Now, go to the very of top of this tree structure and select your computer name, then click OK.

7. Now type "iis apppool\your_apppool_name" and click "Check Names" button. If the apppool exists, you will see your apppool name in the textbox with underline in it. Click OK button.

8. Check/uncheck whatever access you need to grant to the account

9. Click Apply button and then OK.

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

Changing pool from ASP.NET v4.0 to Framework4 worked for me.

I had this weird error and the culprit is a white space on the beginning of the PHP open tag

even without the ob_flush and ob_end_clean

Just make sure there are no extra white spaces on or after any <?php ?> block

The one exception worth noting is that while you can't delete apps, the folks over at Google Play Developer Support are able to on their end if the app is both unpublished and has 0 lifetime installs. So if your app has 0 lifetime installs, you might be in luck.

First you will need unpublish the app and wait 24 hours (to allow global stats to update and ensure that no last-minute installs happened). Assuming no last-minute installs happen over those 24 hours, you can contact Google Play Developer Support and check to see if they can delete it.

Please note that their requirement for 0 installs is a hard requirement. No exceptions can be made (not even if you installed the app yourself for testing purposes).

Using environment variable is sometimes more convenient when you do not control the build scripts / process.

For C includes use C_INCLUDE_PATH.

For C++ includes use CPLUS_INCLUDE_PATH.

See this link for other gcc environment variables.

Example usage in MacOS / Linux

# `pip install` will automatically run `gcc` using parameters
# specified in the `asyncpg` package (that I do not control)

C_INCLUDE_PATH=/home/scott/.pyenv/versions/3.7.9/include/python3.7m pip install asyncpg

Example usage in Windows

set C_INCLUDE_PATH="C:\Users\Scott\.pyenv\versions\3.7.9\include\python3.7m"

pip install asyncpg

# clear the environment variable so it doesn't affect other builds
set C_INCLUDE_PATH=

The Following command displays extra informations

curl -X POST http://httpbin.org/post -v > /dev/null

You can ask server to send just HEAD, instead of full response

curl -X HEAD -I http://httpbin.org/

Note: In some cases, server may send different headers for POST and HEAD. But in almost all cases headers are same.

In a rails 5.1 app, I use this core extension built on top of ActiveRecord::Type::Boolean. It is working perfectly for me when I deserialize boolean from JSON string.

https://api.rubyonrails.org/classes/ActiveModel/Type/Boolean.html

# app/lib/core_extensions/string.rb
module CoreExtensions
  module String
    def to_bool
      ActiveRecord::Type::Boolean.new.deserialize(downcase.strip)
    end
  end
end

initialize core extensions

# config/initializers/core_extensions.rb
String.include CoreExtensions::String

rspec

# spec/lib/core_extensions/string_spec.rb
describe CoreExtensions::String do
  describe "#to_bool" do
    %w[0 f F false FALSE False off OFF Off].each do |falsey_string|
      it "converts #{falsey_string} to false" do
        expect(falsey_string.to_bool).to eq(false)
      end
    end
  end
end

Use WatiN if you need to see the impact of JS on the page [and you're prepared to start a browser]

Properties prop = new Properties();
prop.load(...); // FileInputStream 
prop.setProperty("key", "value");
prop.store(...); // FileOutputStream 

Well, technically '\0' is a character while "\0" is a string, so if you're checking for the null termination character the former is correct. However, as Chris Lutz points out in his answer, your comparison won't work in it's current form.

I worked on both Travis and Jenkins: I will list down some of the features of both:

Setup CI for a project

Travis comes in first place. It's very easy to setup. Takes less than a minute to setup with GitHub.

1. Login to GitHub
2. Create Web Hook for Travis.
3. Return to Travis, and login with your GitHub credentials
4. Sync your GitHub repo and enable Push and Pull requests.

Jenkins:

1. Create an Environment (Master Jenkins)
2. Create web hooks
3. Configure each job (takes time compare to Travis)

Re-running builds

Travis: Anyone with write access on GitHub can re-run the build by clicking on `restart build

Jenkins: Re-run builds based on a phrase. You provide phrase text in PR/commit description, like reverify jenkins.

Controlling environment

Travis: Travis provides hosted environment. It installs required software for every build. It’s a time-consuming process.

Jenkins: One-time setup. Installs all required software on a node/slave machine, and then builds/tests on a pre-installed environment.

Build Logs:

Travis: Supports build logs to place in Amazon S3.

Jenkins: Easy to setup with build artifacts plugin.

If your trying to fade the backgound image but leave the foreground text/images you could use css to separate the background image into a new div and position it over the div containing the text/images then fade the background div.

I think you will have to loop over the "inserted" table, which contains all rows that were updated. You can use a WHERE loop, or a WITH statement if your primary key is a GUID. This is the simpler (for me) to write, so here is my example. We use this approach, so I know for a fact it works fine.

ALTER TRIGGER [dbo].[RA2Newsletter] ON [dbo].[Reiseagent]
    AFTER INSERT
AS
        -- This is your primary key.  I assume INT, but initialize
        -- to minimum value for the type you are using.
        DECLARE @rAgent_ID INT = 0

        -- Looping variable.
        DECLARE @i INT = 0

        -- Count of rows affected for looping over
        DECLARE @count INT

        -- These are your old variables.
        DECLARE @rAgent_Name NVARCHAR(50)
        DECLARE @rAgent_Email NVARCHAR(50)
        DECLARE @rAgent_IP NVARCHAR(50)
        DECLARE @hotelID INT
        DECLARE @retval INT

    BEGIN 
        SET NOCOUNT ON ;

        -- Get count of affected rows
        SELECT  @Count = Count(rAgent_ID)
        FROM    inserted

        -- Loop over rows affected
        WHILE @i < @count
            BEGIN
                -- Get the next rAgent_ID
                SELECT TOP 1
                        @rAgent_ID = rAgent_ID
                FROM    inserted
                WHERE   rAgent_ID > @rAgent_ID
                ORDER BY rAgent_ID ASC

                -- Populate values for the current row
                SELECT  @rAgent_Name = rAgent_Name,
                        @rAgent_Email = rAgent_Email,
                        @rAgent_IP = rAgent_IP,
                        @hotelID = hotelID
                FROM    Inserted
                WHERE   rAgent_ID = @rAgent_ID

                -- Run your stored procedure
                EXEC insert2Newsletter '', '', @rAgent_Name, @rAgent_Email,
                    @rAgent_IP, @hotelID, 'RA', @retval 

                -- Set up next iteration
                SET @i = @i + 1
            END
    END 
GO

I sure hope this helps you out. Cheers!

Is there some handy way of defining direction per column?

No. You cannot specify the sort order other than by a callback function that inverses the value. Not even this is possible for a multicolumn sort.

You might be able to do

 _.each(array_of_objects, function(o) {
     o.typeDesc = -o.type; // assuming a number
 });
 _.sortBy(array_of_objects, ['typeDesc', 'name'])

For everything else, you will need to resort to the native .sort() with a custom comparison function:

 array_of_objects.sort(function(a, b) {
     return a.type - b.type // asc
         || +(b.name>a.name)||-(a.name>b.name) // desc
         || …;
 });

For Swift4 to get weekday from string

   func getDayOfWeek(today:String)->Int {
        let formatter  = DateFormatter()
        formatter.dateFormat = "yyyy-MM-dd"
        let todayDate = formatter.date(from: today)!
        let myCalendar = NSCalendar(calendarIdentifier: NSCalendar.Identifier.gregorian)!
        let myComponents = myCalendar.components(NSCalendar.Unit.weekday, from: todayDate)
        let weekDay = myComponents.weekday
        return weekDay!
    }

let weekday = getDayOfWeek(today: "2018-10-10")
print(weekday) // 4

In case anyone landed on this page for a similar issue, I found that this error can happen if your JavaScript is running in the HEAD before your form is ready. Moving your JavaScript to the bottom of the page fixed it for my situation.

Using the FM format model modifier to get close, as you won't get the trailing zeros after the decimal separator; but you will still get the separator itself, e.g. 50.. You can use rtrim to get rid of that:

select to_char(a, '99D90'),
    to_char(a, '90D90'),
    to_char(a, 'FM90D99'),
    rtrim(to_char(a, 'FM90D99'), to_char(0, 'D'))
from (
    select 50 a from dual
    union all select 50.57 from dual
    union all select 5.57 from dual
    union all select 0.35 from dual
    union all select 0.4 from dual
)
order by a;

TO_CHA TO_CHA TO_CHA RTRIM(
------ ------ ------ ------
   .35   0.35 0.35   0.35
   .40   0.40 0.4    0.4
  5.57   5.57 5.57   5.57
 50.00  50.00 50.    50
 50.57  50.57 50.57  50.57

Note that I'm using to_char(0, 'D') to generate the character to trim, to match the decimal separator - so it looks for the same character, , or ., as the first to_char adds.

The slight downside is that you lose the alignment. If this is being used elsewhere it might not matter, but it does then you can also wrap it in an lpad, which starts to make it look a bit complicated:

...
lpad(rtrim(to_char(a, 'FM90D99'), to_char(0, 'D')), 6)
...

TO_CHA TO_CHA TO_CHA RTRIM( LPAD(RTRIM(TO_CHAR(A,'FM
------ ------ ------ ------ ------------------------
   .35   0.35 0.35   0.35     0.35
   .40   0.40 0.4    0.4       0.4
  5.57   5.57 5.57   5.57     5.57
 50.00  50.00 50.    50         50
 50.57  50.57 50.57  50.57   50.57

You can compile with either Cygwin's g++ or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll (and others) PATH to the system Windows PATH, before any cygwin style paths.

Thus add: ;C:\cygwin64\bin to the end of your Windows system PATH variable.

Also, to compile for use in CMD or PowerShell, you may need to use:

x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe

_{(This invokes the cross-compiler, if installed.)}

With the help of xpath locator also, you can achieve the same.

Your statement would be:

driver.findElement(By.xpath(".//a[contains(@href,'long')]")).click();

And for clicking all the links contains long in the URL, you can use:-

List<WebElement> linksList = driver.findElements(By.xpath(".//a[contains(@href,'long')]"));

for (WebElement webElement : linksList){
         webElement.click();
}

Basic difference : a 8-bit PNG comprises a max. of 256 colors. PNG-24 is a loss-less format and can contain up to 16 million colors.

Impacts:

1. If you are using any round corner image then edges might visible in png8 format.
2. ie6 doesnt support png24 format.

right click on the project and select Manage NuGet Packages.. In that select Json.NET and install

After installation,

use the following namespace

using Newtonsoft.Json;

then use the following to deserialize

JsonConvert.DeserializeObject

Just add 20 minutes in milliseconds to your date:

  var currentDate = new Date();

  currentDate.setTime(currentDate.getTime() + 20*60*1000);

You can use ObjectMapper.convertValue(), either value by value or even for the whole list. But you need to know the type to convert to:

POJO pojo = mapper.convertValue(singleObject, POJO.class);
// or:
List<POJO> pojos = mapper.convertValue(listOfObjects, new TypeReference<List<POJO>>() { });

this is functionally same as if you did:

byte[] json = mapper.writeValueAsBytes(singleObject);
POJO pojo = mapper.readValue(json, POJO.class);

but avoids actual serialization of data as JSON, instead using an in-memory event sequence as the intermediate step.

I also tried the de-compilation thing, it works but recently I found the easiest way:

1. Download and install Appium from Appium website

2. Open Appium->Android setting, choose the target apk file. And then you get everything you want, the package info, activity info.

Although @Remus Rusanu's is already an excelent answer, in case one is looking forward a better insight on SQL Server's Deadlock causes and trace strategies, I would suggest you to read Brad McGehee's How to Track Down Deadlocks Using SQL Server 2005 Profiler

There is timeline.sty floating around.

The syntax is simpler than using tikz:

%%% In LaTeX:
%%% \begin{timeline}{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \end{timeline}
%%%
%%% in plain TeX
%%% \timeline{length}(start,stop)
%%%   .
%%%   .
%%%   .
%%% \endtimeline
%%% in between the two, we may have:
%%% \item{date}{description}
%%% \item[sortkey]{date}{description}
%%% \optrule
%%%
%%% the options to timeline are:
%%%      length The amount of vertical space that the timeline should
%%%                use.
%%%      (start,stop) indicate the range of the timeline. All dates or
%%%                sortkeys should lie in the range [start,stop]
%%%
%%% \item without the sort key expects date to be a number (such as a
%%%      year).
%%% \item with the sort key expects the sort key to be a number; date
%%%      can be anything. This can be used for log scale time lines
%%%      or dates that include months or days.
%%% putting \optrule inside of the timeline environment will cause a
%%%      vertical rule to be drawn down the center of the timeline.

I've used python's datetime.data.toordinal to convert dates to 'sort keys' in the context of the package.

I did it by listening query logs and appending to a log array:

//create query
$query=DB::table(...)...->where(...)...->orderBy(...)...
$log=[];//array of log lines
...
//invoked on query execution if query log is enabled
DB::listen(function ($query)use(&$log){
    $log[]=$query;//enqueue query data to logs
});
//enable query log
DB::enableQueryLog();
$res=$query->get();//execute

jQuery.fn.swap = function(b){ 
    b = jQuery(b)[0]; 
    var a = this[0]; 
    var t = a.parentNode.insertBefore(document.createTextNode(''), a); 
    b.parentNode.insertBefore(a, b); 
    t.parentNode.insertBefore(b, t); 
    t.parentNode.removeChild(t); 
    return this; 
};

and use it like this:

$('#div1').swap('#div2');

if you don't want to use jQuery you could easily adapt the function.

use getBoundingClientRect if $el is the actual DOM object:

var top = $el.getBoundingClientRect().top;

JSFiddle

Fiddle will show that this will get the same value that jquery's offset top will give you

Edit: as mentioned in comments this does not account for scrolled content, below is the code that jQuery uses

https://github.com/jquery/jquery/blob/master/src/offset.js (5/13/2015)

offset: function( options ) {
    //...

    var docElem, win, rect, doc,
        elem = this[ 0 ];

    if ( !elem ) {
        return;
    }

    rect = elem.getBoundingClientRect();

    // Make sure element is not hidden (display: none) or disconnected
    if ( rect.width || rect.height || elem.getClientRects().length ) {
        doc = elem.ownerDocument;
        win = getWindow( doc );
        docElem = doc.documentElement;

        return {
            top: rect.top + win.pageYOffset - docElem.clientTop,
            left: rect.left + win.pageXOffset - docElem.clientLeft
        };
    }
}

I created jquery.backgroundSize.js: a 1.5K jquery plugin that can be used as a IE8 fallback for "cover" and "contain" values. Have a look at the demo.

Solving your problem could be as simple as:

$("h2#news").css({backgroundSize: "cover"});

A Simple and an easy way

var cusid_ele = document.getElementsByClassName('custid');
for (var i = 0; i < cusid_ele.length; ++i) {
    var item = cusid_ele[i];  
    item.innerHTML = 'this is value';
}

You can try this way:

$datetime = new DateTime('2010-12-30 23:21:46');

echo $datetime->format(DATE_ATOM);

My favorite approach, without external libraries:

try {
    URI uri = new URI(name);

    // perform checks for scheme, authority, host, etc., based on your requirements

    if ("mailto".equals(uri.getScheme()) {/*Code*/}
    if (uri.getHost() == null) {/*Code*/}

} catch (URISyntaxException e) {
}

just use this attribute

[System.Web.Http.HttpGet]

not need this line of code:

[System.Web.Http.AcceptVerbs("GET", "POST")]

Some great answers above, using that info here is what I did today to solve the same issue:

$to_array = explode(',', $to);
foreach($to_array as $address)
{
    $mail->addAddress($address, 'Web Enquiry');
}

This might be completely off base, but can't you just copy the whole column into a new spreadsheet and then sort the column? I'm assuming that you don't need to maintain the order integrity.

The most common way would be to put a simple text file (XML/JSON would be better) on your webserver with the last build version. The application will then download this file, check the version and start the updater. A typical file would look like this:

Application Update File (A unique string that will let your application recognize the file type)

version: 1.0.0 (Latest Assembly Version)

download: http://yourserver.com/... (A link to the download version)

redirect: http://yournewserver.com/... (I used this field in case of a change in the server address.)

This would let the client know that they need to be looking at a new address.

You can also add other important details.

I had the same errors with CMake. In my case, I have used the wrong Visual Studio version in the initial CMake dialog where we have to select the Visual Studio compiler.

Then I changed it to "Visual Studio 11 2012" and things worked. (I have Visual Studio Ultimate 2012 version on my PC). In general, try to input an older version of Visual Studio version in the initial CMake configuration dialog.

On a mac / in Terminal:

1. Show Inspector (right click within the terminal window or Shell >Show Inspector)
2. click the Settings icon above "running processes"
3. choose from the list of options under "Signal Process Group" (Kill, terminate, interrupt, etc).

Other alternatives for summing the columns are

numpy.einsum('ij->j', a)

and

numpy.dot(a.T, numpy.ones(a.shape[0]))

If the number of rows and columns is in the same order of magnitude, all of the possibilities are roughly equally fast:

If there are only a few columns, however, both the einsum and the dot solution significantly outperform numpy's sum (note the log-scale):

Code to reproduce the plots:

import numpy
import perfplot


def numpy_sum(a):
    return numpy.sum(a, axis=1)


def einsum(a):
    return numpy.einsum('ij->i', a)


def dot_ones(a):
    return numpy.dot(a, numpy.ones(a.shape[1]))


perfplot.save(
    "out1.png",
    # setup=lambda n: numpy.random.rand(n, n),
    setup=lambda n: numpy.random.rand(n, 3),
    n_range=[2**k for k in range(15)],
    kernels=[numpy_sum, einsum, dot_ones],
    logx=True,
    logy=True,
    xlabel='len(a)',
    )

Currently my build is working. Here you are the steps I tried until it finally worked:

1. Search in the whole project the word CommonCrypto.
2. If you have a Pod containing that header import, remove this Pod from the Podfile and perform a pod install.
3. Clean and build the project.
4. Add again the Pod to the Podfile and perform a pod install.
5. Clean and build the project again using a real device if possible.

And If you don't have that Pod, maybe you can try by making the same steps with some old Pod that you may encounter in your project.

Added information: also If you have some code error inside a Pod, first you need to solve that code problem and then try to compile again the project.

I'm going to copy the changes made in my project.pbxproj. I know it's not very helpful but it's the only thing that have changed in the git difference commit:

Removed: BDC9821B1E9BD1B600ADE0EF /* (null) in Sources */ = {isa = PBXBuildFile; };
Added:   BDC9821B1E9BD1B600ADE0EF /* BuildFile in Sources */ = {isa = PBXBuildFile; };

I hope this can help,

Regards.
