The reply by Phil Sacre was correct however the session shouldn't be used just for the hell of it. You should only use this for values which really need to live for the lifetime of the session, such as a user login. It's common to see people overuse the session and run into more issues, especially when dealing with a collection or when users return to a page they previously visited only to find they have values still remaining from a previous visit. A smart program minimizes the scope of variables as much as possible, a bad one uses session too much.

Experienced the same error, below is the reason and solution that worked for me for mysql-5.7.14-winx64

reason: DATA folder to have some default folders and files which were missing

solution: delete everything from DATA folder, i assume its a fresh installation so backup anything that you need if at all. Then run this from the command prompt and it will create required files and folders "mysqld --initialize --console" now run "mysqld" and it should work well.

There are many ways to take input from the users. I personally like using the method gets. When you use gets, it gets the string that you typed, and that includes the ENTER key that you pressed to end your input.

name = gets
"mukesh\n"

You can see this in irb; type this and you will see the \n, which is the “newline” character that the ENTER key produces: Type name = gets you will see somethings like "mukesh\n" You can get rid of pesky newline character using chomp method.

The chomp method gives you back the string, but without the terminating newline. Beautiful chomp method life saviour.

name = gets.chomp
"mukesh"

You can also use terminal to read the input. ARGV is a constant defined in the Object class. It is an instance of the Array class and has access to all the array methods. Since it’s an array, even though it’s a constant, its elements can be modified and cleared with no trouble. By default, Ruby captures all the command line arguments passed to a Ruby program (split by spaces) when the command-line binary is invoked and stores them as strings in the ARGV array.

When written inside your Ruby program, ARGV will take take a command line command that looks like this:

test.rb hi my name is mukesh

and create an array that looks like this:

["hi", "my", "name", "is", "mukesh"]

But, if I want to passed limited input then we can use something like this.

test.rb 12 23

and use those input like this in your program:

a = ARGV[0]
b = ARGV[1]

Because HTTP is stateless, in order to associate a request to any other request, you need a way to store user data between HTTP requests.

Cookies or URL parameters ( for ex. like http://example.com/myPage?asd=lol&boo=no ) are both suitable ways to transport data between 2 or more request. However they are not good in case you don't want that data to be readable/editable on client side.

The solution is to store that data server side, give it an "id", and let the client only know (and pass back at every http request) that id. There you go, sessions implemented. Or you can use the client as a convenient remote storage, but you would encrypt the data and keep the secret server-side.

Of course there are other aspects to consider, like you don't want people to hijack other's sessions, you want sessions to not last forever but to expire, and so on.

In your specific example, the user id (could be username or another unique ID in your user database) is stored in the session data, server-side, after successful identification. Then for every HTTP request you get from the client, the session id (given by the client) will point you to the correct session data (stored by the server) that contains the authenticated user id - that way your code will know what user it is talking to.

Checkout this jquery window plugin: http://fstoke.me/jquery/window/

// create a window
sampleWnd = $.window({
   .....
});

// resize the window by passed w,h parameter
sampleWnd.resize(screen.width, screen.height);

To get date time with offset like 2019-07-22T13:39:27.397+05:00 Try following Kotlin code:

fun getDateTimeForApiAsString() : String{
    val date = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX", 
                   Locale.getDefault())
    return date.format(Date())
}

Output Formate:

2019-07-22T13:39:27.397+05:00 //for Pakistan

If you want other similar formats replace pattern in SimpleDateFormat as below:

"yyyy.MM.dd G 'at' HH:mm:ss z"  //Output Format: 2001.07.04 AD at 12:08:56 PDT
"EEE, MMM d, ''yy"  //Output Format:    Wed, Jul 4, '01
"h:mm a"      //Output Format: 12:08 PM
"hh 'o''clock' a, zzzz"   //Output Format:  12 o'clock PM, Pacific Daylight Time
"K:mm a, z"  //Output Format:   0:08 PM, PDT
"yyyyy.MMMMM.dd GGG hh:mm aaa"  //Output Format:    02001.July.04 AD 12:08 PM
"EEE, d MMM yyyy HH:mm:ss Z"  //Output Format:  Wed, 4 Jul 2001 12:08:56 -0700
"yyMMddHHmmssZ"  //Output Format:   010704120856-0700
"yyyy-MM-dd'T'HH:mm:ss.SSSZ"  //Output Format:  2001-07-04T12:08:56.235-0700
"yyyy-MM-dd'T'HH:mm:ss.SSSXXX"  //Output Format:    2001-07-04T12:08:56.235-07:00
"YYYY-'W'ww-u"  //Output Format:    2001-W27-3

I think you are looking for this

String[] car = new String[10];
int size = car.length;

Add these two lines near the top of your batch file, all stdout and stderr after will be redirected to log.txt:

if not "%1"=="STDOUT_TO_FILE"  %0 STDOUT_TO_FILE %*  >log.txt 2>&1
shift /1

You can look at the docs for the SlugField to get to know more about it in more descriptive way.

Here's an example that shows how to do sync & async.

import Foundation

class HttpDownloader {

    class func loadFileSync(url: NSURL, completion:(path:String, error:NSError!) -> Void) {
        let documentsUrl =  NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first as! NSURL
        let destinationUrl = documentsUrl.URLByAppendingPathComponent(url.lastPathComponent!)
        if NSFileManager().fileExistsAtPath(destinationUrl.path!) {
            println("file already exists [\(destinationUrl.path!)]")
            completion(path: destinationUrl.path!, error:nil)
        } else if let dataFromURL = NSData(contentsOfURL: url){
            if dataFromURL.writeToURL(destinationUrl, atomically: true) {
                println("file saved [\(destinationUrl.path!)]")
                completion(path: destinationUrl.path!, error:nil)
            } else {
                println("error saving file")
                let error = NSError(domain:"Error saving file", code:1001, userInfo:nil)
                completion(path: destinationUrl.path!, error:error)
            }
        } else {
            let error = NSError(domain:"Error downloading file", code:1002, userInfo:nil)
            completion(path: destinationUrl.path!, error:error)
        }
    }

    class func loadFileAsync(url: NSURL, completion:(path:String, error:NSError!) -> Void) {
        let documentsUrl =  NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first as! NSURL
        let destinationUrl = documentsUrl.URLByAppendingPathComponent(url.lastPathComponent!)
        if NSFileManager().fileExistsAtPath(destinationUrl.path!) {
            println("file already exists [\(destinationUrl.path!)]")
            completion(path: destinationUrl.path!, error:nil)
        } else {
            let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
            let session = NSURLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil)
            let request = NSMutableURLRequest(URL: url)
            request.HTTPMethod = "GET"
            let task = session.dataTaskWithRequest(request, completionHandler: { (data: NSData!, response: NSURLResponse!, error: NSError!) -> Void in
                if (error == nil) {
                    if let response = response as? NSHTTPURLResponse {
                        println("response=\(response)")
                        if response.statusCode == 200 {
                            if data.writeToURL(destinationUrl, atomically: true) {
                                println("file saved [\(destinationUrl.path!)]")
                                completion(path: destinationUrl.path!, error:error)
                            } else {
                                println("error saving file")
                                let error = NSError(domain:"Error saving file", code:1001, userInfo:nil)
                                completion(path: destinationUrl.path!, error:error)
                            }
                        }
                    }
                }
                else {
                    println("Failure: \(error.localizedDescription)");
                    completion(path: destinationUrl.path!, error:error)
                }
            })
            task.resume()
        }
    }
}

Here's how to use it in your code:

let url = NSURL(string: "http://www.mywebsite.com/myfile.pdf") 
HttpDownloader.loadFileAsync(url, completion:{(path:String, error:NSError!) in
                println("pdf downloaded to: \(path)")
            })

As long as you have the firewall set to allow the port that your SQL Server instance is using, all you need to do is change Data Source from =Server name to =IP,Port

ie, in the connection string use something like this.

Data Source=190.190.1.100,1433;

You should not have to change anything on the client side.

I had the exact same problem and it was driving me crazy (Windows 10 and VS Code 1.49.1)

Other answers talk about installing Selenium, but it's clear to me that you've already did that, but you still get the ImportError: No module named 'selenium'.

So, what's going on?

Two things:

1. You installed Selenium in this folder /Library/Python/2.7/site-packages and selenium-2.46.0-py2.7.egg
2. But you're probably running a version of Python, in which you didn't install Selenium. For instance: /Library/Python/3.8/site-packages... you won't find Selenium installed here and that's why the module isn't found.

The solution? You have to install selenium in the same directory to the Python version you're using or change the interpreter to match the directory where Selenium is installed.

In VS Code you change the interpreter here (at the bottom left corner of the screen)

Ready! Now your Python interpreter should find the module.

Once you downloaded your APK file , You need to do the following steps to get a editable java code/document.

1. Convert your apk file to zip (while start your download don't go with "save" option , just go with "save as" and mention your extension as .zip) by doing like this you may avoid APKTOOL...
2. Extract the zip file , there you can find somefilename.dex. so now we need to convert dex -> .class
3. To do that, you need "dex2jar"(you can download it from http://code.google.com/p/dex2jar/ , after extracted, in command prompt you have to mention like, [D:\dex2jar-0.09>dex2jar somefilename.dex] (Keep in mind that your somefilename.dex must be inside the same folder where you have keep your dex2jar.)
4. Download jad from http://www.viralpatel.net/blogs/download/jad/jad.zip and extract it. Once extracted you can see two files like "jad.exe" and "Readme.txt" (sometimes "jad.txt" may there instead of "jad.exe", so just rename its extension as.exe to run)
5. Finally, in command prompt you have to mention like [D:\jad>jad -sjava yourfilename.class] it will parse your class file into editable java document.

insert byte to specific place.

insertToArray(arr,index,item) {
   return Buffer.concat([arr.slice(0,index),Buffer.from(item,"utf-8"),arr.slice(index)]);
}

I couldn't get the above code to work.

Google does a great explanation though here: http://code.google.com/apis/maps/documentation/javascript/basics.html#DetectingUserLocation

Where they first use the W3C Geolocation method and then offer the Google.gears fallback method for older browsers.

The example is here:

http://code.google.com/apis/maps/documentation/javascript/examples/map-geolocation.html

instead of these custom error messages we can specify the type of the text field.

Ex: set type of the field in to type = 'email'

then plugin will identify the field and validate correctly.

if you are using rspec-Webdriver in ruby, you can use this script assuming that an element should really not be present and it is a passed test.

First, write this method first from your class RB file

class Test
 def element_present?
    begin
        browser.find_element(:name, "this_element_id".displayed?
        rescue Selenium::WebDriver::Error::NoSuchElementError
            puts "this element should not be present"
        end
 end

Then, on your spec file, call that method.

  before(:all) do    
    @Test= Test.new(@browser)
  end

 @Test.element_present?.should == nil

If your the element is NOT present, your spec will pass, but if the element is present , it will throw an error, test failed.

I had the same problem where there's no files under Generated Java files, BuildConfig and R.java were missing. The automatic build option is not generating.
In Eclipse under Project, uncheck Build Automatically. Then under Project select Build Project. You may need to fix the projec

in my version of Eclipse helios with m2Eclipse there is no

window --> maven --> Download Artifact Sources (select check)

Under window is only "new window", "new editor" "open perspective" etc.

If you right click on your project, then chose maven--> download sources

Nothing happens. no sources get downloaded, no pom files get updated, no window pops up asking which sources.

Doing mvn xxx outside of eclipse is dangerous - some commands dont work with m2ecilpse - I did that once and lost the entire project, had to reinstall eclipse and start from scratch.

Im still looking for a way to get ecilpse and maven to find and use the source of external jars like servlet-api.

You can't add them directly, you have to make a new array and then copy each of the arrays into the new one. System.arraycopy is a method you can use to perform this copy.

int[] array1and2 = new int[array1.length + array2.length];
System.arraycopy(array1, 0, array1and2, 0, array1.length);
System.arraycopy(array2, 0, array1and2, array1.length, array2.length);

This will work regardless of the size of array1 and array2.

I think developers can do this for their own apps via iTunes Connect but this doesn't help you if you are looking for stats on other peoples apps.

148Apps also have some aggregate AppStore metrics on their web site that could be useful to you but, again, doesn't really give a low-level breakdown of numbers.

You could also scrape some stats from the RSS feeds generated by the iTunes Store RSS Generator but, again, this just gets currently popular apps rather than actual download numbers.

Consider using Regular Expressions or FTP Globbing. By that you could start wget multiple times with different groups of filename starting characters depending on their frequency of occurrence.

This is for example how I sync a folder between two NAS:

wget --recursive --level 0 --no-host-directories --cut-dirs=2 --no-verbose --timestamping --backups=0 --bind-address=10.0.0.10 --user=<ftp_user> --password=<ftp_password> "ftp://10.0.0.100/foo/bar/[0-9a-hA-H]*" --directory-prefix=/volume1/foo &
wget --recursive --level 0 --no-host-directories --cut-dirs=2 --no-verbose --timestamping --backups=0 --bind-address=10.0.0.11 --user=<ftp_user> --password=<ftp_password> "ftp://10.0.0.100/foo/bar/[!0-9a-hA-H]*" --directory-prefix=/volume1/foo &

The first wget syncs all files/folders starting with 0, 1, 2... F, G, H and the second thread syncs everything else.

This was the easiest way to sync between a NAS with one 10G ethernet port (10.0.0.100) and a NAS with two 1G ethernet ports (10.0.0.10 and 10.0.0.11). I bound the two wget threads through --bind-address to the different ethernet ports and called them parallel by putting & at the end of each line. By that I was able to copy huge files with 2x 100 MB/s = 200 MB/s in total.

It can happen when server does not respond due to 100% CPU or Memory utilization.

I got this error when I was trying to access sonarqube API and the server was not responding due to full memory utilization

Check your JNI/native code. One of my references was null, but it was intermittent, so it wasn't very obvious.

The only alternative to using a loop is to use recursion.

You can define a method like

public static int sum(List<Integer> ints) {
   return ints.isEmpty() ? 0 : ints.get(0) + ints.subList(1, ints.length());
}

This is very inefficient compared to using a plain loop and can blow up if you have many elements in the list.

An alternative which avoid a stack overflow is to use.

public static int sum(List<Integer> ints) {
    int len = ints.size();
    if (len == 0) return 0;
    if (len == 1) return ints.get(0);
    return sum(ints.subList(0, len/2)) + sum(ints.subList(len/2, len));
}

This is just as inefficient, but will avoid a stack overflow.

The shortest way to write the same thing is

int sum = 0, a[] = {2, 4, 6, 8};

for(int i: a) {
    sum += i;
}

System.out.println("sum(a) = " + sum);

prints

sum(a) = 20

Try swich fetchType from LAZY to EAGER

...
@OneToMany(fetch=FetchType.EAGER)
private Set<NodeValue> nodeValues;
...

But in this case your app will fetch data from DB anyway. If this query very hard - this may impact on performance. More here: https://docs.oracle.com/javaee/6/api/javax/persistence/FetchType.html

I used a little time to figure this out... I ran it some CastExceptions, but figured out that you can replace you LinearLayout in the layout.xml with the name of the class.

Like this:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/llMaster">

<com.ourshoppingnote.RelativeLayoutThatDetectsSoftKeyboard android:background="@drawable/metal_background"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:id="@+id/rlMaster" >
    <LinearLayout android:layout_width="fill_parent"
        android:layout_height="1dip" android:background="@drawable/line"></LinearLayout>

          ....

</com.ourshoppingnote.RelativeLayoutThatDetectsSoftKeyboard>    


</LinearLayout>

That way you do not run into any cast issues.

... and if you don't want to do this on every page, I recommend that you use "MasterPage in Android". See the link here: http://jnastase.alner.net/archive/2011/01/08/ldquomaster-pagesrdquo-in-android.aspx

By definition arrays are fixed size. You can use instead an Arraylist wich is that, a "dynamic size" array. Actually what happens is that the VM "adjust the size"* of the array exposed by the ArrayList.

See also

*using back-copy arrays

A far more common answer is that you have some error that is getting appended to whatever your compressing. The solution is to set display_errors = Off in your php.ini file (Check in your terminal if it's On by running php --info and look for "display_errors")

That should do it. And, how do you discover what errors you're actually? Check your PHP error logs whenever you hit that route/page.

Good luclk!

A bit late to the party. But this seems to work flawlessly for me

select[readonly] {
    pointer-events:none;
}

Manually cast the sender to the type of your custom control, and then use it to delete or disable etc. Eg, something like this:

private void myCustomControl_Click(object sender, EventArgs e)
{
  ((MyCustomControl)sender).DoWhatever();
}

The 'sender' is just the object that was actioned (eg clicked).

The event args is subclassed for more complex controls, eg a treeview, so that you can know more details about the event, eg exactly where they clicked.

another approach is to use the double colons:

mtcars %>% 
  dplyr::group_by(cyl, gear) %>%
  dplyr::summarise(length(gear))

data="UTF-8 DATA"
udata=data.decode("utf-8")
asciidata=udata.encode("ascii","ignore")

I ran into this problem on NetBeans when working with a ready-made project from this Murach JSP book. The problem was caused by using the 5.1.23 Connector J with a MySQL 8.0.13 Database. I needed to replace the old driver with a new one. After downloading the Connector J, this took three steps.

How to replace NetBeans project Connector J:

1. Download the current Connector J from here. Then copy it in your OS.

2. In NetBeans, click on the Files tab which is next to the Projects tab. Find the mysql-connector-java-5.1.23.jar or whatever old connector you have. Delete this old connector. Paste in the new Connector.

3. Click on the Projects tab. Navigate to the Libraries folder. Delete the old mysql connector. Right click on the Libraries folder. Select Add Jar / Folder. Navigate to the location where you put the new connector, and select open.

4. In the Project tab, right click on the project. Select Resolve Data Sources on the bottom of the popup menu. Click on Add Connection. At this point NetBeans skips forward and assumes you want to use the old connector. Click the Back button to get back to the skipped window. Remove the old connector, and add the new connector. Click Next and Test Connection to make sure it works.

For video reference, I found this to be useful. For IntelliJ IDEA, I found this to be useful.

Firstly, you should use randrange(0,1000) or randint(0,999), not randint(0,1000). The upper limit of randint is inclusive.

For efficiently, randint is simply a wrapper of randrange which calls random, so you should just use random. Also, use xrange as the argument to sample, not range.

You could use

[a for a in sample(xrange(1000),1000) for _ in range(10000/1000)]

to generate 10,000 numbers in the range using sample 10 times.

(Of course this won't beat NumPy.)

$ python2.7 -m timeit -s 'from random import randrange' '[randrange(1000) for _ in xrange(10000)]'
10 loops, best of 3: 26.1 msec per loop

$ python2.7 -m timeit -s 'from random import sample' '[a%1000 for a in sample(xrange(10000),10000)]'
100 loops, best of 3: 18.4 msec per loop

$ python2.7 -m timeit -s 'from random import random' '[int(1000*random()) for _ in xrange(10000)]' 
100 loops, best of 3: 9.24 msec per loop

$ python2.7 -m timeit -s 'from random import sample' '[a for a in sample(xrange(1000),1000) for _ in range(10000/1000)]'
100 loops, best of 3: 3.79 msec per loop

$ python2.7 -m timeit -s 'from random import shuffle
> def samplefull(x):
>   a = range(x)
>   shuffle(a)
>   return a' '[a for a in samplefull(1000) for _ in xrange(10000/1000)]'
100 loops, best of 3: 3.16 msec per loop

$ python2.7 -m timeit -s 'from numpy.random import randint' 'randint(1000, size=10000)'
1000 loops, best of 3: 363 usec per loop

But since you don't care about the distribution of numbers, why not just use:

range(1000)*(10000/1000)

?

You don't "commit the folder" - you add the folder, as you have done, and then simply commit all changes. The command should be:

git add foldername
git commit -m "commit operation"

you can use more elements "end" in print:

for iValue in arr:
   print(iValue, end = ", ");

Just put the following lines at the beginning of any file you want to disable these warnings for.

# pylint: disable=missing-module-docstring
# pylint: disable=missing-class-docstring
# pylint: disable=missing-function-docstring

myWebView.loadData(myHtmlString, "text/html; charset=UTF-8", null);

This works flawlessly, especially on Android 4.0, which apparently ignores character encoding inside HTML.

Tested on 2.3 and 4.0.3.

In fact, I have no idea about what other values besides "base64" does the last parameter take. Some Google examples put null in there.

Let the command you are trying to pass be

os.system('x')

then you covert it to a statement

t = os.system('x')

now the python will be waiting for the output from the commandline so that it could be assigned to the variable t.

UPDATE: Thanks to Bruno Lopes. If several ip addresses could come then need to use this method:

    private string GetUserIP()
    {
        string ipList = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

        if (!string.IsNullOrEmpty(ipList))
        {
            return ipList.Split(',')[0];
        }

        return Request.ServerVariables["REMOTE_ADDR"];
    }

Yes there is a difference between the functions but the way you are using them in this case will result in the same outcome.

path.join returns a normalized path by merging two paths together. It can return an absolute path, but it doesn't necessarily always do so.

For instance:

path.join('app/libs/oauth', '/../ssl')

resolves to app/libs/ssl

path.resolve, on the other hand, will resolve to an absolute path.

For instance, when you run:

path.resolve('bar', '/foo');

The path returned will be /foo since that is the first absolute path that can be constructed.

However, if you run:

path.resolve('/bar/bae', '/foo', 'test');

The path returned will be /foo/test again because that is the first absolute path that can be formed from right to left.

If you don't provide a path that specifies the root directory then the paths given to the resolve function are appended to the current working directory. So if your working directory was /home/mark/project/:

path.resolve('test', 'directory', '../back');

resolves to

/home/mark/project/test/back

Using __dirname is the absolute path to the directory containing the source file. When you use path.resolve or path.join they will return the same result if you give the same path following __dirname. In such cases it's really just a matter of preference.

Actually, the "Checkout to specific local branch" from Claus's answer isn't needed as well.

You can just do changes, execute git commit -am "message" and then use "Git Publisher" with "Branch to push" = /refs/heads/master (or develop or whatever branch you need to push to), "Target remote name" = origin.

'T' and 'Z' are considered here as constants. You need to pass Z without the quotes. Moreover you need to specify the timezone in the input string.

Example : 2013-09-29T18:46:19-0700 And the format as "yyyy-MM-dd'T'HH:mm:ssZ"

As simple as that. Ctrl+F10, then N, to Show or hide line numbers.

Sorry guys for "resurrecting" the thread, but, I hope this will help someone:

In Python3 if you just want to "encapsulate" the class attributes, like in Java, you can just do the same thing like this:

class Simple:
    def __init__(self, str):
        print("inside the simple constructor")
        self.__s = str

    def show(self):
        print(self.__s)

    def showMsg(self, msg):
        print(msg + ':', self.show())

To instantiate this do:

ss = Simple("lol")
ss.show()

Note that: print(ss.__s) will throw an error.

In practice, Python3 will obfuscate the global attribute name. Turning this like a "private" attribute, like in Java. The attribute's name is still global, but in an inaccessible way, like a private attribute in other languages.

But don't be afraid of it. It doesn't matter. It does the job too. ;)

Another thing use "", there is a difference between "\r\n" and '\r\n'.

(You're not searching through "JSON", you're searching through an array -- the JSON string has already been deserialized into an object graph, in this case an array.)

Some options:

Use an Object Instead of an Array

If you're in control of the generation of this thing, does it have to be an array? Because if not, there's a much simpler way.

Say this is your original data:

[
    {"id": "one",   "pId": "foo1", "cId": "bar1"},
    {"id": "two",   "pId": "foo2", "cId": "bar2"},
    {"id": "three", "pId": "foo3", "cId": "bar3"}
]

Could you do the following instead?

{
    "one":   {"pId": "foo1", "cId": "bar1"},
    "two":   {"pId": "foo2", "cId": "bar2"},
    "three": {"pId": "foo3", "cId": "bar3"}
}

Then finding the relevant entry by ID is trivial:

id = "one"; // Or whatever
var entry = objJsonResp[id];

...as is updating it:

objJsonResp[id] = /* New value */;

...and removing it:

delete objJsonResp[id];

This takes advantage of the fact that in JavaScript, you can index into an object using a property name as a string -- and that string can be a literal, or it can come from a variable as with id above.

Putting in an ID-to-Index Map

(Dumb idea, predates the above. Kept for historical reasons.)

It looks like you need this to be an array, in which case there isn't really a better way than searching through the array unless you want to put a map on it, which you could do if you have control of the generation of the object. E.g., say you have this originally:

[
    {"id": "one",   "pId": "foo1", "cId": "bar1"},
    {"id": "two",   "pId": "foo2", "cId": "bar2"},
    {"id": "three", "pId": "foo3", "cId": "bar3"}
]

The generating code could provide an id-to-index map:

{
    "index": {
        "one": 0, "two": 1, "three": 2
    },
    "data": [
        {"id": "one",   "pId": "foo1", "cId": "bar1"},
        {"id": "two",   "pId": "foo2", "cId": "bar2"},
        {"id": "three", "pId": "foo3", "cId": "bar3"}
    ]
}

Then getting an entry for the id in the variable id is trivial:

var index = objJsonResp.index[id];
var obj = objJsonResp.data[index];

This takes advantage of the fact you can index into objects using property names.

Of course, if you do that, you have to update the map when you modify the array, which could become a maintenance problem.

But if you're not in control of the generation of the object, or updating the map of ids-to-indexes is too much code and/ora maintenance issue, then you'll have to do a brute force search.

Brute Force Search (corrected)

Somewhat OT (although you did ask if there was a better way :-) ), but your code for looping through an array is incorrect. Details here, but you can't use for..in to loop through array indexes (or rather, if you do, you have to take special pains to do so); for..in loops through the properties of an object, not the indexes of an array. Your best bet with a non-sparse array (and yours is non-sparse) is a standard old-fashioned loop:

var k;
for (k = 0; k < someArray.length; ++k) { /* ... */ }

or

var k;
for (k = someArray.length - 1; k >= 0; --k) { /* ... */ }

Whichever you prefer (the latter is not always faster in all implementations, which is counter-intuitive to me, but there we are). (With a sparse array, you might use for..in but again taking special pains to avoid pitfalls; more in the article linked above.)

Using for..in on an array seems to work in simple cases because arrays have properties for each of their indexes, and their only other default properties (length and their methods) are marked as non-enumerable. But it breaks as soon as you set (or a framework sets) any other properties on the array object (which is perfectly valid; arrays are just objects with a bit of special handling around the length property).

Here follows a simple solution 100% based on CSS. The "secret" is to use the display: inline-block in the wrapper element. The vertical-align: bottom in the image is a hack to overcome the 4px padding that some browsers add after the element.

Advice: if the element before the wrapper is inline they can end up nested. In this case you can "wrap the wrapper" inside a container with display: block - usually a good and old div.

.wrapper {_x000D_
    display: inline-block;_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.hover {_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    left: 0;_x000D_
    right: 0;_x000D_
    bottom: 0;_x000D_
    background-color: rgba(0, 188, 212, 0);_x000D_
    transition: background-color 0.5s;_x000D_
}_x000D_
_x000D_
.hover:hover {_x000D_
    background-color: rgba(0, 188, 212, 0.8);_x000D_
    // You can tweak with other background properties too (ie: background-image)..._x000D_
}_x000D_
_x000D_
img {_x000D_
    vertical-align: bottom;_x000D_
}

<div class="wrapper">_x000D_
    <div class="hover"></div>_x000D_
    <img src="http://placehold.it/450x250" />_x000D_
</div>

select * from table where column_date > now()- INTERVAL '6 hours';

This does it:

Do
   c = c + 1
Loop While Cells(c, "A").Value <> ""

'prints the last empty row
Debug.Print c

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

@laryx-decidua: I think you are only seeing the 18.x instant client releases that are in the ol7_oci_included repo. The 19.x instant client RPMs, at the moment, are only in the ol7_oracle_instantclient repo. Easiest way to access that repo is:

yum install oracle-release-el7

Those are called #include guards.

Once the header is included, it checks if a unique value (in this case HEADERFILE_H) is defined. Then if it's not defined, it defines it and continues to the rest of the page.

When the code is included again, the first ifndef fails, resulting in a blank file.

That prevents double declaration of any identifiers such as types, enums and static variables.

? extends HasWord

means "A class/interface that extends HasWord." In other words, HasWord itself or any of its children... basically anything that would work with instanceof HasWord plus null.

In more technical terms, ? extends HasWord is a bounded wildcard, covered in Item 31 of Effective Java 3rd Edition, starting on page 139. The same chapter from the 2nd Edition is available online as a PDF; the part on bounded wildcards is Item 28 starting on page 134.

Update: PDF link was updated since Oracle removed it a while back. It now points to the copy hosted by the Queen Mary University of London's School of Electronic Engineering and Computer Science.

Update 2: Lets go into a bit more detail as to why you'd want to use wildcards.

If you declare a method whose signature expect you to pass in List<HasWord>, then the only thing you can pass in is a List<HasWord>.

However, if said signature was List<? extends HasWord> then you could pass in a List<ChildOfHasWord> instead.

Note that there is a subtle difference between List<? extends HasWord> and List<? super HasWord>. As Joshua Bloch put it: PECS = producer-extends, consumer-super.

What this means is that if you are passing in a collection that your method pulls data out from (i.e. the collection is producing elements for your method to use), you should use extends. If you're passing in a collection that your method adds data to (i.e. the collection is consuming elements your method creates), it should use super.

This may sound confusing. However, you can see it in List's sort command (which is just a shortcut to the two-arg version of Collections.sort). Instead of taking a Comparator<T>, it actually takes a Comparator<? super T>. In this case, the Comparator is consuming the elements of the List in order to reorder the List itself.

import inspect

def func(a,b,c=5):
    pass

inspect.getargspec(func)  # inspect.signature(func) in Python 3

(['a', 'b', 'c'], None, None, (5,))

There could be a few things happening here. Start by first figuring out your library location:

Sys.getenv("R_LIBS_USER")

or

.libPaths()

We already know yours from the info you gave: C:\Program Files\R\R-3.0.1\library

I believe you have a file in there called: 00LOCK. From ?install.packages:

Note that it is possible for the package installation to fail so badly that the lock directory is not removed: this inhibits any further installs to the library directory (or for --pkglock, of the package) until the lock directory is removed manually.

You need to delete that file. If you had the pacman package installed you could have simply used p_unlock() and the 00LOCK file is removed. You can't install pacman now until the 00LOCK file is removed.

To install pacman use:

install.packages("pacman")

There may be a second issue. This is where you somehow corrupted MASS. This can occur, in my experience, if you try to update a package while it is in use in another R session. I'm sure there's other ways to cause this as well. To solve this problem try:

1. Close out of all R sessions (use task manager to ensure you're truly R session free) Ctrl + Alt + Delete
2. Go to your library location Sys.getenv("R_LIBS_USER"). In your case this is: C:\Program Files\R\R-3.0.1\library
3. Manually delete the MASS package
4. Fire up a vanilla session of R
5. Install MASS via install.packages("MASS")

If any of this works please let me know what worked.

You just need to transfer the first value to float, before it gets involved in further computations:

float z = x * 1.0 / y;

Note that you can use a variable in a slice:

l = ['a',' b',' c',' d',' e']
c_index = l.index("c")
l2 = l[:c_index]

This would put the first two entries of l in l2

The correct and easiest way is to use Stack Views.

1. Add your labels/views to the Stack View:

2. Select the Stack View and set Distribution to be Equal Spacing:

3. Add Spacing to nearest neighbor constraints to the Stack View and update frames:

4. Add Height constraints to all the labels (optional). Needed only for views that does not have Intrinsic Size). Labels for example does not need here height constrains and only need to set numberOfLines = 3 or 0 for example.

5. Enjoy Preview:

The other answers to this question seem to hit it spot on. Now how would you figure this out for yourself without stack overflow? Check out IPython, an interactive Python shell that has tab auto-complete.

press tab a few times and you'll be prompted with the members of the "now" object:

now.__add__           now.__gt__            now.__radd__          now.__sub__           now.fromordinal       now.microsecond       now.second            now.toordinal         now.weekday

and you'll see that now.year is a member of the "now" object.

You could try this method:

Public Class MyUtilities
    Shared Sub RunCommandCom(command as String, arguments as String, permanent as Boolean) 
        Dim p as Process = new Process() 
        Dim pi as ProcessStartInfo = new ProcessStartInfo() 
        pi.Arguments = " " + if(permanent = true, "/K" , "/C") + " " + command + " " + arguments 
        pi.FileName = "cmd.exe" 
        p.StartInfo = pi 
        p.Start() 
    End Sub
End Class

call, for example, in this way:

MyUtilities.RunCommandCom("DIR", "/W", true)

EDIT: For the multiple command on one line the key are the & | && and || command connectors

• A & B → execute command A, then execute command B.
• A | B → execute command A, and redirect all it's output into the input of command B.
• A && B → execute command A, evaluate the errorlevel after running Command A, and if the exit code (errorlevel) is 0, only then execute command B.
• A || B → execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute command B.

Here's an ES6 version, conversion to vanilla JS shouldn't be too hard but I already have jQuery anyways:

function select(options, selected) {_x000D_
  return Object.entries(options).reduce((r, [k, v]) => r.append($('<option>').val(k).text(v)), $('<select>')).val(selected);_x000D_
}_x000D_
$('body').append(select({'option1': 'label 1', 'option2': 'label 2'}, 'option2'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>

  public Bitmap scaleBitmap(Bitmap mBitmap) {
        int ScaleSize = 250;//max Height or width to Scale
        int width = mBitmap.getWidth();
        int height = mBitmap.getHeight();
        float excessSizeRatio = width > height ? width / ScaleSize : height / ScaleSize;
         Bitmap bitmap = Bitmap.createBitmap(
                mBitmap, 0, 0,(int) (width/excessSizeRatio),(int) (height/excessSizeRatio));
        //mBitmap.recycle(); if you are not using mBitmap Obj
        return bitmap;
    }

I think this represents a good answer.

APK Signature Scheme v2 verification

1. Locate the APK Signing Block and verify that:
   1. Two size fields of APK Signing Block contain the same value.
   2. ZIP Central Directory is immediately followed by ZIP End of Central Directory record.
   3. ZIP End of Central Directory is not followed by more data.
2. Locate the first APK Signature Scheme v2 Block inside the APK Signing Block. If the v2 Block if present, proceed to step 3. Otherwise, fall back to verifying the APK using v1 scheme.
3. For each signer in the APK Signature Scheme v2 Block:
   1. Choose the strongest supported signature algorithm ID from signatures. The strength ordering is up to each implementation/platform version.
   2. Verify the corresponding signature from signatures against signed data using public key. (It is now safe to parse signed data.)
   3. Verify that the ordered list of signature algorithm IDs in digests and signatures is identical. (This is to prevent signature stripping/addition.)
   4. Compute the digest of APK contents using the same digest algorithm as the digest algorithm used by the signature algorithm.
   5. Verify that the computed digest is identical to the corresponding digest from digests.
   6. Verify that SubjectPublicKeyInfo of the first certificate of certificates is identical to public key.
4. Verification succeeds if at least one signer was found and step 3 succeeded for each found signer.

Note: APK must not be verified using the v1 scheme if a failure occurs in step 3 or 4.

JAR-signed APK verification (v1 scheme)

The JAR-signed APK is a standard signed JAR, which must contain exactly the entries listed in META-INF/MANIFEST.MF and where all entries must be signed by the same set of signers. Its integrity is verified as follows:

1. Each signer is represented by a META-INF/<signer>.SF and META-INF/<signer>.(RSA|DSA|EC) JAR entry.
2. <signer>.(RSA|DSA|EC) is a PKCS #7 CMS ContentInfo with SignedData structure whose signature is verified over the <signer>.SF file.
3. <signer>.SF file contains a whole-file digest of the META-INF/MANIFEST.MF and digests of each section of META-INF/MANIFEST.MF. The whole-file digest of the MANIFEST.MF is verified. If that fails, the digest of each MANIFEST.MF section is verified instead.
4. META-INF/MANIFEST.MF contains, for each integrity-protected JAR entry, a correspondingly named section containing the digest of the entry’s uncompressed contents. All these digests are verified.
5. APK verification fails if the APK contains JAR entries which are not listed in the MANIFEST.MF and are not part of JAR signature. The protection chain is thus <signer>.(RSA|DSA|EC) ? <signer>.SF ? MANIFEST.MF ? contents of each integrity-protected JAR entry.

Could you please try this ?

Create another item in post such as post.link then assign the link to it before send post to the render function.

post.link = '/posts/+ id.toString();

So, the above render function should be following instead.

return <li key={post.id}><a href={post.link}>{post.title}</a></li>

Changing the AssemblyInfo works in VS2012. It seems strange that there's not more support for this in Visual Studio, you'd think this was a basic part of the build/release process.

Considering that you are using OpenCV, the best way to convert between data types is to use normalize function.

img_n = cv2.normalize(src=img, dst=None, alpha=0, beta=255, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_8U)

However, if you don't want to use OpenCV, you can do this in numpy

def convert(img, target_type_min, target_type_max, target_type):
    imin = img.min()
    imax = img.max()

    a = (target_type_max - target_type_min) / (imax - imin)
    b = target_type_max - a * imax
    new_img = (a * img + b).astype(target_type)
    return new_img

And then use it like this

imgu8 = convert(img16u, 0, 255, np.uint8)

This is based on the answer that I found on crossvalidated board in comments under this solution https://stats.stackexchange.com/a/70808/277040

Yes, the syntax is accurate and it should be fine.

Here is the SQL Fiddle Demo I created for your particular case

create table sample2
(
    id int primary key,
    created_date date,
    data varchar(10)
  )

insert into sample2 values (1,'2012-01-01','testing');

And here is how to select the data

SELECT Created_Date
FROM sample2
WHERE Created_Date >= DATEADD(day,-11117, GETDATE())

How about:

conditions = [a, b, c]
if any(conditions) and not all(conditions):
   ...

Other variant:

if 1 <= sum(map(bool, conditions)) <= 2:
   ...

Assuming your products LINQ class uses a similar yield for enumerating/iterating, the first version is more efficient because its only yielding one value each time its iterated over.

The second example is converting the enumerator/iterator to a list with the ToList() method. This means it manually iterates over all the items in the enumerator and then returns a flat list.

Here are the most common reasons

• Incorrect file paths

• File names are misspelled

• Wrong file extension

• Files are missing

• The read permission has not been set for the image(s)

Note: On *nix systems, consider using the following command to add read permission for an image:

chmod o+r imagedirectoryAddress/imageName.extension

or this command to add read permission for all images:

chmod o+r imagedirectoryAddress/*.extension

For anyone experiencing this on windows after an update

What happened was that Windows Defender made some changes. Possibly cause running data extraction scripts, but python.exe got reduced to 0kb for that project. Copying the python.exe from another project and replacing it solved for now.

In simple, using Comparator and Collection you can sort like below in reversal order using JAVA 8

import java.util.Comparator;;
import java.util.stream.Collectors;

Arrays.asList(files).stream()
    .sorted(Comparator.comparing(File::getLastModified).reversed())
    .collect(Collectors.toList());

After thorough research I found the solution

Encoding

    let plainData = (plainString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
    let base64String =plainData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.fromRaw(0)!)
    println(base64String) // bXkgcGxhbmkgdGV4dA==

Decoding

    let decodedData = NSData(base64EncodedString: base64String, options:NSDataBase64DecodingOptions.fromRaw(0)!)
    let decodedString = NSString(data: decodedData, encoding: NSUTF8StringEncoding)    
    println(decodedString) // my plain data

You can instanciate LocalReport

                FicheInscriptionBean fiche = new FicheInscriptionBean();
                fiche.ToFicheInscriptionBean(inscription);List<FicheInscriptionBean> list = new List<FicheInscriptionBean>();
                list.Add(fiche);
                ReportDataSource rds = new ReportDataSource();
                rds = new ReportDataSource("InscriptionDataSet", list);
                // attachement du QrCode.
                string stringToCode = numinscription + "," + inscription.Nom + "," + inscription.Prenom + "," + inscription.Cin;
                Bitmap BitmapCaptcha = PostulerFiche.GenerateQrCode(fiche.NumInscription + ":" + fiche.Cin, Brushes.Black, Brushes.White, 200);
                MemoryStream ms = new MemoryStream();
                BitmapCaptcha.Save(ms, ImageFormat.Gif);
                var base64Data = Convert.ToBase64String(ms.ToArray());
                string QR_IMG = base64Data;
                ReportParameter parameter = new ReportParameter("QR_IMG", QR_IMG, true);

                LocalReport report = new LocalReport();
                report.ReportPath = Page.Server.MapPath("~/rdlc/FicheInscription.rdlc");
                report.DataSources.Clear();
                report.SetParameters(new ReportParameter[] { parameter });
                report.DataSources.Add(rds);
                report.Refresh();

                string FileName = "FichePreinscription_" + numinscription + ".pdf";
                string extension;
                string encoding;
                string mimeType;
                string[] streams;
                Warning[] warnings;
                Byte[] mybytes = report.Render("PDF", null,
                              out extension, out encoding,
                              out mimeType, out streams, out warnings);
                using (FileStream fs = File.Create(Server.MapPath("~/rdlc/Reports/" + FileName)))
                {
                    fs.Write(mybytes, 0, mybytes.Length);
                }
                Response.ClearHeaders();
                Response.ClearContent();
                Response.Buffer = true;
                Response.Clear();
                Response.Charset = "";
                Response.ContentType = "application/pdf";
                Response.AddHeader("Content-Disposition", "attachment;filename=\"" + FileName + "\"");
                Response.WriteFile(Server.MapPath("~/rdlc/Reports/" + FileName));

                Response.Flush();
                File.Delete(Server.MapPath("~/rdlc/Reports/" + FileName));
                Response.Close();
                Response.End();

I have found the solution else where:

SELECT SUBSTRING(master.dbo.fn_varbintohexstr(HashBytes('MD5', 'HelloWorld')), 3, 32)

Another possible case (but rare) could be if you have server to server communications and have set server.maxConnections to a very low value.

In node's core lib net.js it will call clientHandle.close() which will also cause error ECONNRESET:

if (self.maxConnections && self._connections >= self.maxConnections) {
  clientHandle.close(); // causes ECONNRESET on the other end
  return;
}

If you use UTF-8 encoding then one character can takes a various number of bytes (2 - 4). For PL/SQL the varchar2 limit is 32767 bytes, not characters. See how I increase a PL/SQL varchar2 variable of the 4000 character size:

SQL> set serveroutput on
SQL> l
  1  declare
  2    l_var varchar2(30000);
  3  begin
  4    l_var := rpad('A', 4000);
  5    dbms_output.put_line(length(l_var));
  6    l_var := l_var || rpad('B', 10000);
  7    dbms_output.put_line(length(l_var));
  8* end;
SQL> /
4000
14000

PL/SQL procedure successfully completed.

But you can't insert into your table the value of such variable:

SQL> ed
Wrote file afiedt.buf

  1  create table ttt (
  2    col1 varchar2(2000 char)
  3* )
SQL> /

Table created.

SQL> ed
Wrote file afiedt.buf

  1  declare
  2    l_var varchar2(30000);
  3  begin
  4      l_var := rpad('A', 4000);
  5      dbms_output.put_line(length(l_var));
  6      l_var := l_var || rpad('B', 10000);
  7      dbms_output.put_line(length(l_var));
  8      insert into ttt values (l_var);
  9* end;
SQL> /
4000
14000
declare
*
ERROR at line 1:
ORA-01461: can bind a LONG value only for insert into a LONG column
ORA-06512: at line 8

As a solution, you can try to split this variable's value into several parts (SUBSTR) and store them separately.

This answer could be really late, but its useful.

You can play youtube videos in the app itself using android-youtube-player.

Some code snippets:

To play a youtube video that has a video id in the url, you simply call the OpenYouTubePlayerActivity intent

Intent intent = new Intent(null, Uri.parse("ytv://"+v), this, 
            OpenYouTubePlayerActivity.class);
startActivity(intent);

where v is the video id.

Add the following permissions in the manifest file:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

and also declare this activity in the manifest file:

<activity 
        android:name="com.keyes.youtube.OpenYouTubePlayerActivity"></activity>

Further information can be obtained from the first portions of this code file.

Hope that helps anyone!

As mentioned, sealed is an equivalent of final for methods and classes.

As for the rest, it is complicated.

• For static final fields, static readonly is the closest thing possible. It allows you to initialize the static field in a static constructor, which is fairly similar to static initializer in Java. This applies both to constants (primitives and immutable objects) and constant references to mutable objects.

  The const modifier is fairly similar for constants, but you can't set them in a static constructor.

• On a field that shouldn't be reassigned once it leaves the constructor, readonly can be used. It is not equal though - final requires exactly one assignment even in constructor or initializer.

• There is no C# equivalent for a final local variable that I know of. If you are wondering why would anyone need it: You can declare a variable prior to an if-else, switch-case or so. By declaring it final, you enforce that it is assigned at most once.

  Java local variables in general are required to be assigned at least once before they are read. Unless the branch jumps out before value read, a final variable is assigned exactly once. All of this is checked compile-time. This requires well behaved code with less margin for an error.

Summed up, C# has no direct equivalent of final. While Java lacks some nice features of C#, it is refreshing for me as mostly a Java programmer to see where C# fails to deliver an equivalent.

You are trying to pass pointers (which you do not delete, thus leaking memory) where references are needed. You do not really need pointers here:

Complex firstComplexNumber(81, 93);
Complex secondComplexNumber(31, 19);

cout << "Numarul complex este: " << firstComplexNumber << endl;
//                                  ^^^^^^^^^^^^^^^^^^ No need to dereference now

// ...

Complex::distanta(firstComplexNumber, secondComplexNumber);

Open the Terminal and write:

swift -version

If you want to disable client side validation for a form in HTML5 add a novalidate attribute to the form element. Ex:

<form method="post" action="/foo" novalidate>...</form>

See https://www.w3.org/TR/html5/sec-forms.html#element-attrdef-form-novalidate

This may work for those of us who use different os/systems, but want to get the best of all worlds:

import os
workers = os.cpu_count()
if 'sched_getaffinity' in dir(os):
    workers = len(os.sched_getaffinity(0))

You can use angularjs form state form.$submitted. Initially form.$submitted value will be false and will became true after successful form submit.

The link_tag() helper is clearly the way to do this. Put your css where it usually belongs, in site_root/css/ and then use the helper:

From The CodeIgniter docs...

echo link_tag('css/mystyles.css');

Output

<link href="http://example.com/css/mystyles.css" rel="stylesheet" type="text/css" />

Well, you could make a custom function:

function custom_echo($x, $length)
{
  if(strlen($x)<=$length)
  {
    echo $x;
  }
  else
  {
    $y=substr($x,0,$length) . '...';
    echo $y;
  }
}

You use it like this:

<?php custom_echo($row['style-info'], 200); ?>

You can try this...

<div class="image">

      <img src="" alt="" />

      <h2>Text you want to display over the image</h2>

</div>

CSS

.image { 
   position: relative; 
   width: 100%; /* for IE 6 */
}

h2 { 
   position: absolute; 
   top: 200px; 
   left: 0; 
   width: 100%; 
}

The other answers work for floating point numbers, but do not correctly compute the distance for integer dtypes which are subject to overflow and underflow. Note that even scipy.distance.euclidean has this issue:

>>> a1 = np.array([1], dtype='uint8')
>>> a2 = np.array([2], dtype='uint8')
>>> a1 - a2
array([255], dtype=uint8)
>>> np.linalg.norm(a1 - a2)
255.0
>>> from scipy.spatial import distance
>>> distance.euclidean(a1, a2)
255.0

This is common, since many image libraries represent an image as an ndarray with dtype="uint8". This means that if you have a greyscale image which consists of very dark grey pixels (say all the pixels have color #000001) and you're diffing it against black image (#000000), you can end up with x-y consisting of 255 in all cells, which registers as the two images being very far apart from each other. For unsigned integer types (e.g. uint8), you can safely compute the distance in numpy as:

np.linalg.norm(np.maximum(x, y) - np.minimum(x, y))

For signed integer types, you can cast to a float first:

np.linalg.norm(x.astype("float") - y.astype("float"))

For image data specifically, you can use opencv's norm method:

import cv2
cv2.norm(x, y, cv2.NORM_L2)

I am deploying VB6 IIS Applications to my remote dedicated server with 75 folders. The reason I was getting this error is the Default Document was not set on one of the folders, an oversight, so the URL hitting that folder did not know which page to server up, and thus threw the error mentioned in this thread.

Just add the following rules to the parent element:

display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */

Here's a sample demo (Resize window to see the image align)

Browser support for Flexbox nowadays is quite good.

For cross-browser compatibility for display: flex and align-items, you can add the older flexbox syntax as well:

display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;

You need

$('body').click(function(e) {
    if (!$(e.target).closest('.popup').length){
        $(".popup").hide();
    }
});

you can wrap -Andrie answer into a generic function

mbind<-function(...){
 Reduce( function(x,y){cbind(x,y[match(row.names(x),row.names(y)),])}, list(...) )
}

Here, you can bind multiple frames with rownames as key

Tried the above solutions with no luck ... restarted my mac solved the issue...

Try making your property nullable.

    public DateTime? Time{ get; set; }

Worked for me.

Summary

Assuming ordering is not important:

• If you are going to build large table once and do lots of queries, use std::unordered_map
• If you are going to build small table (may be under 100 elements) and do lots of queries, use std::map. This is because reads on it are O(log n).
• If you are going to change table a lot then may be std::map is good option.
• If you are in doubt, just use std::unordered_map.

Historical Context

In most languages, unordered map (aka hash based dictionaries) are the default map however in C++ you get ordered map as default map. How did that happen? Some people erroneously assume that C++ committee made this decision in their unique wisdom but the truth is unfortunately uglier than that.

It is widely believed that C++ ended up with ordered map as default because there are not too many parameters on how they can be implemented. On the other hand, hash based implementations has tons of things to talk about. So to avoid gridlocks in standardization they just got along with ordered map. Around 2005, many languages already had good implementations of hash based implementation and so it was more easier for the committee to accept new std::unordered_map. In a perfect world, std::map would have been unordered and we would have std::ordered_map as separate type.

Performance

Below two graphs should speak for themselves (source):

If you are doing this often then it is better to stove it away in a helper function:

def index_of(val, in_list):
    try:
        return in_list.index(val)
    except ValueError:
        return -1 

I tried many of the above suggestions, including SuperSU and couldn't get any to work but found something much simpler that worked for my purposes. In my case, I only wanted to be able to run sqlite at the command prompt. I simply spun up an emulator with an older version of Android (Lollipop) and got root access immediately.

Assuming popup is the ID of your "description box":

HTML

<div id="parent"> <!-- This is the main container, to mouse over -->
<div id="popup" style="display: none">description text here</div>
</div>

JavaScript

var e = document.getElementById('parent');
e.onmouseover = function() {
  document.getElementById('popup').style.display = 'block';
}
e.onmouseout = function() {
  document.getElementById('popup').style.display = 'none';
}

Alternatively you can get rid of JavaScript entirely and do it just with CSS:

CSS

#parent #popup {
  display: none;
}

#parent:hover #popup {
  display: block;
}

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

Regarding to Android documentation it can be achieve by using following code line:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

I have added this in my onCreate method and it works fine.

On the link you will find different ways to achieve this and general explanation as well.

Link to the documenation: https://developer.android.com/training/scheduling/wakelock.html

If you want to see only the date of a tag you'd do:

git show -s --format=%ci <mytagname>^{commit}

which gives: 2013-11-06 13:22:37 +0100

Or do:

git show -s --format=%ct <mytagname>^{commit}

which gives UNIX timestamp: 1383740557

Why not

DELETE FROM table ORDER BY id DESC LIMIT 1, 123456789

Just delete all but the first row (order is DESC!), using a very very large nummber as second LIMIT-argument. See here

I'm think this has been answered before...but anyway, if you want to encrypt/decrypt data, you can't use SHA256

//Key
$key = 'SuperSecretKey';

//To Encrypt:
$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, 'I want to encrypt this', MCRYPT_MODE_ECB);

//To Decrypt:
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $encrypted, MCRYPT_MODE_ECB);

I know that is a old question, but...

You can also use this in your class:

@Autowired
private HttpServletRequest context;

And this will provide the current instance of HttpServletRequest for you use on your method.

If you're writing a bash script, call it by name:

#!/bin/bash

/bin/sh is not guaranteed to be bash. This caused a ton of broken scripts in Ubuntu some years ago (IIRC).

The source builtin works just fine in bash; but you might as well just use dot like Norman suggested.

This maybe help somebody who is looking for the way to sort table by two columns, but in paralel way. This means to combine two sorts using aggregate sorting function. It's very useful when for example retrieving articles using fulltext search and also concerning the article publish date.

This is only example, but if you catch the idea you can find a lot of aggregate functions to use. You can even weight the columns to prefer one over second. The function of mine takes extremes from both sorts, thus the most valued rows are on the top.

Sorry if there exists simplier solutions to do this job, but I haven't found any.

SELECT
 `id`,
 `text`,
 `date`
 FROM
   (
   SELECT
     k.`id`,
     k.`text`,
     k.`date`,
     k.`match_order_id`,
     @row := @row + 1 as `date_order_id`
     FROM
     (
       SELECT
         t.`id`,
         t.`text`,
         t.`date`,
         @row := @row + 1 as `match_order_id`
         FROM
         (
           SELECT
             `art_id` AS `id`,
             `text`   AS `text`,
             `date`   AS `date`,
             MATCH (`text`) AGAINST (:string) AS `match`
             FROM int_art_fulltext
             WHERE MATCH (`text`) AGAINST (:string IN BOOLEAN MODE)
             LIMIT 0,101
         ) t,
         (
           SELECT @row := 0
         ) r
         ORDER BY `match` DESC
     ) k,
     (
       SELECT @row := 0
     ) l
     ORDER BY k.`date` DESC
   ) s
 ORDER BY (1/`match_order_id`+1/`date_order_id`) DESC

Set data to this:

data ={"eventType":"AAS_PORTAL_START","data":{"uid":"hfe3hf45huf33545","aid":"1","vid":"1"}}

In html its used along with limitTo filter provided by angular itself as below,

    <p> {{limitTo:30 | keepDots }} </p>

filter keepDots :

     App.filter('keepDots' , keepDots)

       function keepDots() {

        return function(input,scope) {
            if(!input) return;

             if(input.length > 20)
                return input+'...';
            else
                return input;

        }


    }

One (++i) is preincrement, one (i++) is postincrement. The difference is in what value is immediately returned from the expression.

// Psuedocode
int i = 0;
print i++; // Prints 0
print i; // Prints 1
int j = 0;
print ++j; // Prints 1
print j; // Prints 1

Edit: Woops, entirely ignored the loop side of things. There's no actual difference in for loops when it's the 'step' portion (for(...; ...; )), but it can come into play in other cases.

Using itertools.count:

import itertools
for i in itertools.count(start=1):
    if there_is_a_reason_to_break(i):
        break

In Python 2, range() and xrange() were limited to sys.maxsize. In Python 3 range() can go much higher, though not to infinity:

import sys
for i in range(sys.maxsize**10):  # you could go even higher if you really want
    if there_is_a_reason_to_break(i):
        break

So it's probably best to use count().

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

This seems ridiculous and far fetched but you could always use Windows (or whatever OS you prefer) to manage the sound for you!

import os
os.system("start C:/thepathyouwant/file")

Simple, no extensions, somewhat slow and junky, but working.

Here is my function for export database into device storage

private void exportDB(){
    String DatabaseName = "Sycrypter.db";
    File sd = Environment.getExternalStorageDirectory();
    File data = Environment.getDataDirectory();
    FileChannel source=null;
    FileChannel destination=null;
    String currentDBPath = "/data/"+ "com.synnlabz.sycryptr" +"/databases/"+DatabaseName ;
    String backupDBPath = SAMPLE_DB_NAME;
    File currentDB = new File(data, currentDBPath);
    File backupDB = new File(sd, backupDBPath);
    try {
        source = new FileInputStream(currentDB).getChannel();
        destination = new FileOutputStream(backupDB).getChannel();
        destination.transferFrom(source, 0, source.size());
        source.close();
        destination.close();
        Toast.makeText(this, "Your Database is Exported !!", Toast.LENGTH_LONG).show();
    } catch(IOException e) {
        e.printStackTrace();
    }
}

Here is my function for import database from device storage into android application

I just had the same issue and solved it by changing

src: url("Roboto-Medium-webfont.eot?#iefix")

to

src: url("Roboto-Medium-webfont.eot?#iefix") format('embedded-opentype')

I would recommend to use an existing tool such as monit, it will monitor and auto restart processes. There is more information available here. It should be easily available in most distributions.

I use the below code . Check if it helps .

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape android:shape="rectangle" >

I'm an early adopter and implemented a mid-large single page application using the Facebook Flux library.

As I'm a little late to the conversation I'll just point out that despite my best hopes Facebook seem to consider their Flux implementation to be a proof of concept and it has never received the attention it deserves.

I'd encourage you to play with it, as it exposes more of the inner working of the Flux architecture which is quite educational, but at the same time it does not provide many of the benefits that libraries like Redux provide (which aren't that important for small projects, but become very valuable for bigger ones).

We have decided that moving forward we will be moving to Redux and I suggest you do the same ;)

/** Count max number of nonempty cells in sheet rows */
private int getColumnsCount(XSSFSheet xssfSheet) {
    int result = 0;
    Iterator<Row> rowIterator = xssfSheet.iterator();
    while (rowIterator.hasNext()) {
        Row row = rowIterator.next();
        List<Cell> cells = new ArrayList<>();
        Iterator<Cell> cellIterator = row.cellIterator();
        while (cellIterator.hasNext()) {
            cells.add(cellIterator.next());
        }
        for (int i = cells.size(); i >= 0; i--) {
            Cell cell = cells.get(i-1);
            if (cell.toString().trim().isEmpty()) {
                cells.remove(i-1);
            } else {
                result = cells.size() > result ? cells.size() : result;
                break;
            }
        }
    }
    return result;
}

Utilizing the "dynamic table" capability in SQL Server (querying against a parenthesis-surrounded query), you can return 2000, 49 w/ the following. If your platform doesn't offer an equivalent to the "dynamic table" ANSI-extention, you can always utilize a temp table in two-steps/statement by inserting the results within the "dynamic table" to a temp table, and then performing a subsequent select on the temp table.

DECLARE  @T TABLE(
    [contract] INT,
    project INT,
    activity INT
)

INSERT INTO @T VALUES( 1000,    8000,    10 )
INSERT INTO @T VALUES( 1000,    8000,    20 )
INSERT INTO @T VALUES( 1000,    8001,    10 )
INSERT INTO @T VALUES( 2000,    9000,    49 )
INSERT INTO @T VALUES( 2000,    9001,    49 )
INSERT INTO @T VALUES( 3000,    9000,    79 )
INSERT INTO @T VALUES( 3000,    9000,    78 )

SELECT
    [contract],
    [Activity] =  max (activity)
FROM
    (
    SELECT
        [contract],
        [Activity]
    FROM
        @T
    GROUP BY
        [contract],
        [Activity]
    ) t
GROUP BY
    [contract]
HAVING count (*) = 1

I'm facing a similar problem. I'm using Query by Example and I want to sort the results by a custom field. In SQL I would do something like:

select pageNo, abs(pageNo - 434) as diff
from relA
where year = 2009
order by diff

It works fine without the order-by-clause. What I got is

Criteria crit = getSession().createCriteria(Entity.class);
crit.add(exampleObject);
ProjectionList pl = Projections.projectionList();
pl.add( Projections.property("id") );
pl.add(Projections.sqlProjection("abs(`pageNo`-"+pageNo+") as diff", new String[] {"diff"}, types ));
crit.setProjection(pl);

But when I add

crit.addOrder(Order.asc("diff"));

I get a org.hibernate.QueryException: could not resolve property: diff exception. Workaround with this does not work either.

PS: as I could not find any elaborate documentation on the use of QBE for Hibernate, all the stuff above is mainly trial-and-error approach

With the Material Components Library you can use the MaterialShapeDrawable.

    <TextView
        android:id="@+id/textview"
        .../>

Then you can programmatically apply a MaterialShapeDrawable:

    TextView textView = findViewById(R.id.textview);
    MaterialShapeDrawable shapeDrawable = new MaterialShapeDrawable();
    shapeDrawable.setFillColor(ContextCompat.getColorStateList(this,android.R.color.transparent));
    shapeDrawable.setStroke(1.0f, ContextCompat.getColor(this,R.color....));
    ViewCompat.setBackground(textView,shapeDrawable);

try this,

$(".head h3").html("New header");

or

$(".head h3").text("New header");

remember class selectors returns all the matching elements.

This is how I did it:

I added the connection string at appsettings.json

"ConnectionStrings": {
"conStr": "Server=MYSERVER;Database=MYDB;Trusted_Connection=True;MultipleActiveResultSets=true"},

I created a class called SqlHelper

public class SqlHelper
{
    //this field gets initialized at Startup.cs
    public static string conStr;

    public static SqlConnection GetConnection()
    {
        try
        {
            SqlConnection connection = new SqlConnection(conStr);
            return connection;
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }
    }
}

At the Startup.cs I used ConfigurationExtensions.GetConnectionString to get the connection,and I assigned it to SqlHelper.conStr

public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
        SqlHelper.connectionString = ConfigurationExtensions.GetConnectionString(this.Configuration, "conStr");
    }

Now wherever you need the connection string you just call it like this:

SqlHelper.GetConnection();

An adaption from praneybehl answer to work with nested objects and tab separator

  let array = typeof objArray != 'object' ? JSON.parse(objArray) : objArray;
  if(!Array.isArray(array))

  for (let i = 0; i < array.length; i++) {
    let line = '';
    for (let index in array[i]) {
      if (line != '') line += ','

      const item = array[i][index];
      line += (typeof item === 'object' && item !== null ? ConvertToCSV(item) : item);
    }
    str += line + '\r\n';
  }

  do{
      str = str.replace(',','\t').replace('\t\t', '\t');
  }while(str.includes(',') || str.includes('\t\t'));

  return str.replace(/(\r\n|\n|\r)/gm, ""); //removing line breaks: https://stackoverflow.com/a/10805198/4508758
}

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

How you detect EOF depends on what you're using to read the stream:

function                  result on EOF or error                    
--------                  ----------------------
fgets()                   NULL
fscanf()                  number of succesful conversions
                            less than expected
fgetc()                   EOF
fread()                   number of elements read
                            less than expected

Check the result of the input call for the appropriate condition above, then call feof() to determine if the result was due to hitting EOF or some other error.

Using fgets():

 char buffer[BUFFER_SIZE];
 while (fgets(buffer, sizeof buffer, stream) != NULL)
 {
   // process buffer
 }
 if (feof(stream))
 {
   // hit end of file
 }
 else
 {
   // some other error interrupted the read
 }

Using fscanf():

char buffer[BUFFER_SIZE];
while (fscanf(stream, "%s", buffer) == 1) // expect 1 successful conversion
{
  // process buffer
}
if (feof(stream)) 
{
  // hit end of file
}
else
{
  // some other error interrupted the read
}

Using fgetc():

int c;
while ((c = fgetc(stream)) != EOF)
{
  // process c
}
if (feof(stream))
{
  // hit end of file
}
else
{
  // some other error interrupted the read
}

Using fread():

char buffer[BUFFER_SIZE];
while (fread(buffer, sizeof buffer, 1, stream) == 1) // expecting 1 
                                                     // element of size
                                                     // BUFFER_SIZE
{
   // process buffer
}
if (feof(stream))
{
  // hit end of file
}
else
{
  // some other error interrupted read
}

Note that the form is the same for all of them: check the result of the read operation; if it failed, then check for EOF. You'll see a lot of examples like:

while(!feof(stream))
{
  fscanf(stream, "%s", buffer);
  ...
}

This form doesn't work the way people think it does, because feof() won't return true until after you've attempted to read past the end of the file. As a result, the loop executes one time too many, which may or may not cause you some grief.

This code (example) :

    Chronology ch1 = GregorianChronology.getInstance();     Chronology ch2 = ISOChronology.getInstance();      DateTime dt = new DateTime("2013-12-31T22:59:21+01:00",ch1);     DateTime dt2 = new DateTime("2013-12-31T22:59:21+01:00",ch2);      System.out.println(dt);     System.out.println(dt2);      boolean b = dt.equals(dt2);      System.out.println(b); 

Will print :

2013-12-31T16:59:21.000-05:00 2013-12-31T16:59:21.000-05:00 false 

You are probably comparing two DateTimes with same date but different Chronology.

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

I ran into a similar issue when trying to get composer to install some dependencies. It turns out the .dll my version of Wamp came with had a conflict, I am guessing, with 64 bit Windows.

This url has fixed curl dlls: http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Scroll down to the section that says: Fixed Curl Extensions.

I downloaded "php_curl-5.4.3-VC9-x64.zip". I just overwrote the dll inside the wamp/bin/php/php5.4.3/ext directory with the dll that was in the zip file and composer worked again.

I am running 64 bit Windows 8.

Hope this helps.

You can also use strdup:

char* p = strdup("abc");

If maven is not creating Local Repository i.e .m2/repository folder then try below step.

In your Eclipse\Spring Tool Suite, Go to Window->preferences-> maven->user settings-> click on Restore Defaults-> Apply->Apply and close

Addendum to @sjngm's answer:

They both also ignore whitespace:

var foo = " 3 "; console.log(parseInt(foo)); // 3 console.log(Number(foo)); // 3

It is not exactly correct. As sjngm wrote parseInt parses string to first number. It is true. But the problem is when you want to parse number separated with whitespace ie. "12 345". In that case
parseInt("12 345") will return 12 instead of 12345. So to avoid that situation you must trim whitespaces before parsing to number. My solution would be:

     var number=parseInt("12 345".replace(/\s+/g, ''),10);

Notice one extra thing I used in parseInt() function. parseInt("string",10) will set the number to decimal format. If you would parse string like "08" you would get 0 because 8 is not a octal number.Explanation is here

    cd %userprofile%\.android
    dir

np.random.random_sample(size) will generate random floats in the half-open interval [0.0, 1.0).

That is quite simpler way to do it:

ls -l | tr -s " " " " | cut -d " " -f 5,9 | sort -n -r | head -n 1***

And you'll get this: 8445 examples.desktop

What I use:

class Enum(object):
    def __init__(self, names, separator=None):
        self.names = names.split(separator)
        for value, name in enumerate(self.names):
            setattr(self, name.upper(), value)
    def tuples(self):
        return tuple(enumerate(self.names))

How to use:

>>> state = Enum('draft published retracted')
>>> state.DRAFT
0
>>> state.RETRACTED
2
>>> state.FOO
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
AttributeError: 'Enum' object has no attribute 'FOO'
>>> state.tuples()
((0, 'draft'), (1, 'published'), (2, 'retracted'))

So this gives you integer constants like state.PUBLISHED and the two-tuples to use as choices in Django models.

One of the possible implementations:

File file = new File("userdata.xml");
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory
        .newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse(file);
String usr = document.getElementsByTagName("user").item(0).getTextContent();
String pwd = document.getElementsByTagName("password").item(0).getTextContent();

when used with the XML content:

<credentials>
    <user>testusr</user>
    <password>testpwd</password>
</credentials>

results in "testusr" and "testpwd" getting assigned to the usr and pwd references above.

Checking null with normal equality will also return true for undefined.

if (window.variable == null) alert('variable is null or undefined');

You can use swiftmailer for it. By using batch process.

<?php
    $message = Swift_Message::newInstance()
      ->setSubject('Let\'s get together today.')
      ->setFrom(array('[email protected]' => 'From Me'))
      ->setBody('Here is the message itself')
      ->addPart('<b>Test message being sent!!</b>', 'text/html');

    $data = mysql_query('SELECT first, last, email FROM users WHERE is_active=1') or die(mysql_error());
    while($row = mysql_fetch_assoc($data))
    {
       $message->addTo($row['email'], $row['first'] . ' ' . $row['last']);
    }

    $message->batchSend();
?>

I believe in Oracle it means order by column #1

Could you not have simply added:

align-items:center;

to a new class in your row div. Essentially:

<div class="row align_center">

.align_center { align-items:center; }

I suspect that the SelectedItem property of the ComboBox does not change until the control has been validated (which occurs when the control loses focus), whereas the SelectedValue property changes whenever the user selects an item.

Here is a reference to the focus events that occur on controls:

If you are using auto-generated Mongo Object Ids in your document, it contains timestamp in it as first 4 bytes using which latest doc inserted into the collection could be found out. I understand this is an old question, but if someone is still ending up here looking for one more alternative.

db.collectionName.aggregate(
[{$group: {_id: null, latestDocId: { $max: "$_id"}}}, {$project: {_id: 0, latestDocId: 1}}])

Above query would give the _id for the latest doc inserted into the collection

You need to git add my_project to stage your new folder. Then git add my_project/* to stage its contents. Then commit what you've staged using git commit and finally push your changes back to the source using git push origin master (I'm assuming you wish to push to the master branch).

If you can live with 01 for January instead of 1, then try...

d = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print datetime.date.strftime(d, "%m/%d/%y")

You can check the docs for other formatting directives.

As a button value is an attribute you need to use the .attr() method in jquery. This should do it

<script type="text/javascript">
    $(document).ready(function() {
        $('.my_button').click(function() {
            alert($(this).attr("value"));
        });
    });
</script>

You can also use attr to set attributes, more info in the docs.

This only works in JQuery 1.6+. See postpostmodern's answer for older versions.

I ended up coding a custom solution (Firefox extension) that does this. I think by the time I developed it, the commandline mentioned in enreas wasn't there.

The Firefox extension is CmdShots. It's a good option if you need finer degree of control over the process of taking the screenshot (or you want to do some HTML/JS modifications and image processing).

You can use it and abuse it. I decided to keep it unlicensed, so you are free to play with it as you want.

The JPA specification says the following about persist().

If X is a detached object, the EntityExistsException may be thrown when the persist operation is invoked, or the EntityExistsException or another PersistenceException may be thrown at flush or commit time.

So using persist() would be suitable when the object ought not to be a detached object. You might prefer to have the code throw the PersistenceException so it fails fast.

Although the specification is unclear, persist() might set the @GeneratedValue @Id for an object. merge() however must have an object with the @Id already generated.

Per this npm issue list, one work around could be done through npm config

name: 'foo'
config: { path: "baz" },
scripts: { start: "node ./$npm_package_config_path" }

Under windows, the scripts could be { start: "node ./%npm_package_config_path%" }

Then run the command line as below

npm start --foo:path=myapp

I have used lodash "unset" to make it happen for nested object also.. only this need to write small logic to get path of property key which expected by omit method.

1. Method which returns property path as array

var a = {"bool":{"must":[{"range":{"price_index.final_price":{"gt":"450","lt":"500"}}},{"bool":{"should":[{"term":{"color_value.keyword":"Black"}}]}}]}};_x000D_
_x000D_
function getPathOfKey(object,key,currentPath, t){_x000D_
     var currentPath = currentPath || [];_x000D_
_x000D_
    for(var i in object){_x000D_
  if(i == key){_x000D_
        t = currentPath;_x000D_
      }_x000D_
      else if(typeof object[i] == "object"){_x000D_
        currentPath.push(i)_x000D_
       return getPathOfKey(object[i], key,currentPath)_x000D_
      }_x000D_
    }_x000D_
 t.push(key);_x000D_
    return t;_x000D_
}_x000D_
document.getElementById("output").innerHTML =JSON.stringify(getPathOfKey(a,"price_index.final_price"))

<div id="output"> _x000D_
_x000D_
</div>

1. Then just using lodash unset method remove property from object.

var unset = require('lodash.unset');_x000D_
unset(a,getPathOfKey(a,"price_index.final_price"));

Assuming the following method to test:

public boolean doSomething(SomeClass arg);

Mockito documentation says that you should not use captor in this way:

when(someObject.doSomething(argumentCaptor.capture())).thenReturn(true);
assertThat(argumentCaptor.getValue(), equalTo(expected));

Because you can just use matcher during stubbing:

when(someObject.doSomething(eq(expected))).thenReturn(true);

But verification is a different story. If your test needs to ensure that this method was called with a specific argument, use ArgumentCaptor and this is the case for which it is designed:

ArgumentCaptor<SomeClass> argumentCaptor = ArgumentCaptor.forClass(SomeClass.class);
verify(someObject).doSomething(argumentCaptor.capture());
assertThat(argumentCaptor.getValue(), equalTo(expected));

The memory must be configured in several places.
Set memory_limit to 512M:

sudo vi /etc/php5/cgi/php.ini
sudo vi /etc/php5/cli/php.ini
sudo vi /etc/php5/apache2/php.ini Or /etc/php5/fpm/php.ini

Restart service:

sudo service service php5-fpm restart
sudo service service nginx restart

or

sudo service apache2 restart

Finally it should solve the problem of the memory_limit

Replacing all AppSettings

This is the overkill case where you just want to replace an entire section of the web.config. In this case I will replace all AppSettings in the web.config will new settings in web.release.config. This is my baseline web.config appSettings:

<appSettings>
  <add key="KeyA" value="ValA"/>
  <add key="KeyB" value="ValB"/>
</appSettings>

Now in my web.release.config file, I am going to create a appSettings section except I will include the attribute xdt:Transform=”Replace” since I want to just replace the entire element. I did not have to use xdt:Locator because there is nothing to locate – I just want to wipe the slate clean and replace everything.

<appSettings xdt:Transform="Replace">
  <add key="ProdKeyA" value="ProdValA"/>
  <add key="ProdKeyB" value="ProdValB"/>
  <add key="ProdKeyC" value="ProdValC"/>
</appSettings>

Note that in the web.release.config file my appSettings section has three keys instead of two, and the keys aren’t even the same. Now let’s look at the generated web.config file what happens when we publish:

<appSettings>
   <add key="ProdKeyA" value="ProdValA"/>
   <add key="ProdKeyB" value="ProdValB"/>
   <add key="ProdKeyC" value="ProdValC"/>
 </appSettings>

Just as we expected – the web.config appSettings were completely replaced by the values in web.release config. That was easy!

Just add

position: relative;
top: 50%;
transform: translateY(-50%);

to the inner div.

What it does is moving the inner div's top border to the half height of the outer div (top: 50%;) and then the inner div up by half its height (transform: translateY(-50%)). This will work with position: absolute or relative.

Keep in mind that transform and translate have vendor prefixes which are not included for simplicity.

You can try Microsoft's Face API. It can detect and identify people. learn more about face API here.

The quickest way to echo all json values is using loop in loop, the first loop is going to get all the objects and the second one the values...

foreach($data as $object) {

        foreach($object as $value) {

            echo $value;

        }

    }

As far I can understand the original problem, you added commits to local master by mistake and did not push that changes yet. Now you want to cancel your changes and hope to delete your local changes and to create a new master branch from the remote one.

You can just reset your changes and reload master from remote server:

git reset --hard origin/master

Full working implementation of how to detect orientation change in Swift 3.0.

I chose to use this implementation because phone orientations of face up and face down were important to me, and I wanted the view to change only once I knew the orientation was in the specified position.

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        //1
        NotificationCenter.default.addObserver(self, selector: #selector(deviceOrientationDidChange), name: NSNotification.Name.UIDeviceOrientationDidChange, object: nil)

    }

    deinit {
        //3
        NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIDeviceOrientationDidChange, object: nil)
    }

    func deviceOrientationDidChange() {
        //2
        switch UIDevice.current.orientation {
        case .faceDown:
            print("Face down")
        case .faceUp:
            print("Face up")
        case .unknown:
            print("Unknown")
        case .landscapeLeft:
            print("Landscape left")
        case .landscapeRight:
            print("Landscape right")
        case .portrait:
            print("Portrait")
        case .portraitUpsideDown:
            print("Portrait upside down")
        }
    }

}

The important pieces to note are:

1. You listen to the DeviceOrientationDidChange notification stream and tie it to the function deviceOrientationDidChange
2. You then switch on the device orientation, be sure to take notice that there is an unknown orientation at times.
3. Like any notification, before the viewController is deinitialized, make sure to stop observing the notification stream.

Hope someone finds this helpful.

For others that stumble on this, you can also use ejs params/props in conditional statements:

recipes.js File:

app.get("/recipes", function(req, res) {
    res.render("recipes.ejs", {
        recipes: recipes
    });
});

recipes.ejs File:

<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>

Not Bootstrap specific really... You can use inline styles or define a custom class to specify the desired "background-color".

On the other hand, Bootstrap does have a few built in background colors that have semantic meaning like "bg-success" (green) and "bg-danger" (red).

I had the same issue, and the answer was in the dmenu source code: the stest utility made for that purpose. You can compile the 'stest.c' and 'arg.h' files and it should work. There is a man page for the usage, that I put there for convenience:

STEST(1)         General Commands Manual         STEST(1)

       [file...]

DESCRIPTION
       stest takes a list of files  and  filters  by  the
       files'  properties,  analogous  to test(1).  Files
       which pass all tests are printed to stdout. If  no
       files are given, stest reads files from stdin.

OPTIONS
       -a     Test hidden files.

       -b     Test that files are block specials.

       -c     Test that files are character specials.

       -d     Test that files are directories.

       -e     Test that files exist.

       -f     Test that files are regular files.

       -g     Test  that  files  have  their set-group-ID
              flag set.

       -h     Test that files are symbolic links.

       -l     Test the contents of a directory  given  as
              an argument.

       -n file
              Test that files are newer than file.

       -o file
              Test that files are older than file.

       -p     Test that files are named pipes.

       -q     No  files are printed, only the exit status
              is returned.

       -r     Test that files are readable.

       -s     Test that files are not empty.

       -u     Test that files have their set-user-ID flag
              set.

       -v     Invert  the  sense  of  tests, only failing
              files pass.

       -w     Test that files are writable.

       -x     Test that files are executable.

EXIT STATUS

Not sure if this is the best way to do it, but this makes the spinners disappear on Chrome 8.0.552.5 dev:

Normally this error means that a connection was established with a server but that connection was closed by the remote server. This could be due to a slow server, a problem with the remote server, a network problem, or (maybe) some kind of security error with data being sent to the remote server but I find that unlikely.

Normally a network error will resolve itself given a bit of time, but it sounds like you’ve already given it a bit of time.

cURL sometimes having issue with SSL and SSL certificates. I think that your Apache and/or PHP was compiled with a recent version of the cURL and cURL SSL libraries plus I don't think that OpenSSL was installed in your web server.

Although I can not be certain However, I believe cURL has historically been flakey with SSL certificates, whereas, Open SSL does not.

Anyways, try installing Open SSL on the server and try again and that should help you get rid of this error.

rather then using the '/' for the call to split, better to use the Path.DirectorySeparatorChar :

like so:

path.split(Path.DirectorySeparatorChar).Last() 

in a Visual Basic Macro you would use

pName = ActiveWorkbook.Path      ' the path of the currently active file
wbName = ActiveWorkbook.Name     ' the file name of the currently active file
shtName = ActiveSheet.Name       ' the name of the currently selected worksheet

The first sheet in a workbook can be referenced by

ActiveWorkbook.Worksheets(1)

so after deleting the [Report] tab you would use

ActiveWorkbook.Worksheets("Report").Delete
shtName = ActiveWorkbook.Worksheets(1).Name

to "work on that sheet later on" you can create a range object like

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(shtName).[A1]

and continue working on MySheet(rowNum, colNum) etc. ...

shortcut creation of a range object without defining shtName:

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(1).[A1]

Note: Traditionally the use of the label tag is for menus. eg:

<menu>
<label>Option 1</label>
<input type="radio" id="opt1">

<label>Option 2</label>
<input type="radio" id="opt2">

<label>Option 3</label>
<input type="radio" id="opt3">  
</menu>

Here's an approach that could resolve your problem, and if not would help with troubleshooting.

1. Create a second Apache virtual server identical to the current one

2. Send all "normal" user traffic to the original virtual server

3. Send special or long-running traffic to the new virtual server

Special or long-running traffic could be report-generation, maintenance ops or anything else you don't expect to complete in <<1 second. This can happen serving APIs, not just web pages.

If your resource utilization is low but you still exceed MaxClients, the most likely answer is you have new connections arriving faster than they can be serviced. Putting any slow operations on a second virtual server will help prove if this is the case. Use the Apache access logs to quantify the effect.

    },1000);

To run an executable in mac

1). Move to the path of the file:

cd/PATH_OF_THE_FILE

2). Run the following command to set the file's executable bit using the chmod command:

chmod +x ./NAME_OF_THE_FILE

3). Run the following command to execute the file:

./NAME_OF_THE_FILE

Once you have run these commands, going ahead you just have to run command 3, while in the files path.

There is no JavaScript function to achieve this. However, you could set a boolean value to true when you add the listener, and false when you remove it. Then check against this boolean before potentially adding a duplicate event listener.

I would say that it's preferable to use as few special characters as possible in REST URLs. One of the benefits of REST is that it makes the "interface" for a service easy to read. Camel case or Pascal case is probably good for the resource names (Users or users). I don't think there are really any hard standards around REST.

Also, I think Gandalf is right, it's usually cleaner in REST to not use query string parameters, but instead create paths that define which resources you want to deal with.

I ran into a very similar situation as you. Most of the searches I came across stated all I needed to do was set the Owner of the windows I wish to be Topmost to the main window or whatever window that called Show.

Anyways, I'll go ahead and post a solution that worked well for me.

I created event handlers for Window.Activated and Window.Deactived in the window that was supposed to be Topmost with respect to my application.

private void Window_Activated(object sender, EventArgs e)
{
    Topmost = true;
}

private void Window_Deactived(object sender, EventArgs e)
{
    if(Owner == null || Owner.IsActive)
        return;
    bool hasActiveWindow = false;
    foreach(Window ownedWindow in Owner.OwnedWindows)
    {
        if(ownedWindow.IsActive)
            hasActiveWindow = true; 
    }

    if(!hasActiveWindow)
        Topmost = false;
}

It works great for me. Hopefully this is useful to someone else out there. :o)

You can also move your file in a sudoers used directory :

    sudo mv $HOME/bash/script.sh /usr/sbin/ 

Download make.exe from their official site GnuWin32

• In the Download session, click Complete package, except sources.

• Follow the installation instructions.

• Once finished, add the <installation directory>/bin/ to the PATH variable.

Now you will be able to use make in cmd.

Units:

The amount of "neurons", or "cells", or whatever the layer has inside it.

It's a property of each layer, and yes, it's related to the output shape (as we will see later). In your picture, except for the input layer, which is conceptually different from other layers, you have:

• Hidden layer 1: 4 units (4 neurons)
• Hidden layer 2: 4 units
• Last layer: 1 unit

Shapes

Shapes are consequences of the model's configuration. Shapes are tuples representing how many elements an array or tensor has in each dimension.

Ex: a shape (30,4,10) means an array or tensor with 3 dimensions, containing 30 elements in the first dimension, 4 in the second and 10 in the third, totaling 30*4*10 = 1200 elements or numbers.

The input shape

What flows between layers are tensors. Tensors can be seen as matrices, with shapes.

In Keras, the input layer itself is not a layer, but a tensor. It's the starting tensor you send to the first hidden layer. This tensor must have the same shape as your training data.

Example: if you have 30 images of 50x50 pixels in RGB (3 channels), the shape of your input data is (30,50,50,3). Then your input layer tensor, must have this shape (see details in the "shapes in keras" section).

Each type of layer requires the input with a certain number of dimensions:

• Dense layers require inputs as (batch_size, input_size)
  • or (batch_size, optional,...,optional, input_size)
• 2D convolutional layers need inputs as:
  • if using channels_last: (batch_size, imageside1, imageside2, channels)
  • if using channels_first: (batch_size, channels, imageside1, imageside2)
• 1D convolutions and recurrent layers use (batch_size, sequence_length, features)
  • Details on how to prepare data for recurrent layers

Now, the input shape is the only one you must define, because your model cannot know it. Only you know that, based on your training data.

All the other shapes are calculated automatically based on the units and particularities of each layer.

Relation between shapes and units - The output shape

Given the input shape, all other shapes are results of layers calculations.

The "units" of each layer will define the output shape (the shape of the tensor that is produced by the layer and that will be the input of the next layer).

Each type of layer works in a particular way. Dense layers have output shape based on "units", convolutional layers have output shape based on "filters". But it's always based on some layer property. (See the documentation for what each layer outputs)

Let's show what happens with "Dense" layers, which is the type shown in your graph.

A dense layer has an output shape of (batch_size,units). So, yes, units, the property of the layer, also defines the output shape.

• Hidden layer 1: 4 units, output shape: (batch_size,4).
• Hidden layer 2: 4 units, output shape: (batch_size,4).
• Last layer: 1 unit, output shape: (batch_size,1).

Weights

Weights will be entirely automatically calculated based on the input and the output shapes. Again, each type of layer works in a certain way. But the weights will be a matrix capable of transforming the input shape into the output shape by some mathematical operation.

In a dense layer, weights multiply all inputs. It's a matrix with one column per input and one row per unit, but this is often not important for basic works.

In the image, if each arrow had a multiplication number on it, all numbers together would form the weight matrix.

Shapes in Keras

Earlier, I gave an example of 30 images, 50x50 pixels and 3 channels, having an input shape of (30,50,50,3).

Since the input shape is the only one you need to define, Keras will demand it in the first layer.

But in this definition, Keras ignores the first dimension, which is the batch size. Your model should be able to deal with any batch size, so you define only the other dimensions:

input_shape = (50,50,3)
    #regardless of how many images I have, each image has this shape        

Optionally, or when it's required by certain kinds of models, you can pass the shape containing the batch size via batch_input_shape=(30,50,50,3) or batch_shape=(30,50,50,3). This limits your training possibilities to this unique batch size, so it should be used only when really required.

Either way you choose, tensors in the model will have the batch dimension.

So, even if you used input_shape=(50,50,3), when keras sends you messages, or when you print the model summary, it will show (None,50,50,3).

The first dimension is the batch size, it's None because it can vary depending on how many examples you give for training. (If you defined the batch size explicitly, then the number you defined will appear instead of None)

Also, in advanced works, when you actually operate directly on the tensors (inside Lambda layers or in the loss function, for instance), the batch size dimension will be there.

• So, when defining the input shape, you ignore the batch size: input_shape=(50,50,3)
• When doing operations directly on tensors, the shape will be again (30,50,50,3)
• When keras sends you a message, the shape will be (None,50,50,3) or (30,50,50,3), depending on what type of message it sends you.

Dim

And in the end, what is dim?

If your input shape has only one dimension, you don't need to give it as a tuple, you give input_dim as a scalar number.

So, in your model, where your input layer has 3 elements, you can use any of these two:

• input_shape=(3,) -- The comma is necessary when you have only one dimension
• input_dim = 3

But when dealing directly with the tensors, often dim will refer to how many dimensions a tensor has. For instance a tensor with shape (25,10909) has 2 dimensions.

Defining your image in Keras

Keras has two ways of doing it, Sequential models, or the functional API Model. I don't like using the sequential model, later you will have to forget it anyway because you will want models with branches.

PS: here I ignored other aspects, such as activation functions.

With the Sequential model:

from keras.models import Sequential  
from keras.layers import *  

model = Sequential()    

#start from the first hidden layer, since the input is not actually a layer   
#but inform the shape of the input, with 3 elements.    
model.add(Dense(units=4,input_shape=(3,))) #hidden layer 1 with input

#further layers:    
model.add(Dense(units=4)) #hidden layer 2
model.add(Dense(units=1)) #output layer   

With the functional API Model:

from keras.models import Model   
from keras.layers import * 

#Start defining the input tensor:
inpTensor = Input((3,))   

#create the layers and pass them the input tensor to get the output tensor:    
hidden1Out = Dense(units=4)(inpTensor)    
hidden2Out = Dense(units=4)(hidden1Out)    
finalOut = Dense(units=1)(hidden2Out)   

#define the model's start and end points    
model = Model(inpTensor,finalOut)

Shapes of the tensors

Remember you ignore batch sizes when defining layers:

• inpTensor: (None,3)
• hidden1Out: (None,4)
• hidden2Out: (None,4)

It's just what it says:

inputFile = open((x), encoding = "utf8", "r")

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

Use this code it will help you.

<script>
InitializeDate();
</script>




<input type="text" id="txtFromDate" class="datepicker calendar-icon" placeholder="From Date" style="width: 100px; margin-right: 10px; padding: 0px 0px 0px 7px;">
        <input type="text" id="txtToDate" class="datepicker calendar-icon" placeholder="To Date" style="width: 100px; margin-right: 10px; padding: 0px 0px 0px 7px;">


function InitializeDate() {
    var date = new Date();
    var dd = date.getDate();             
    var mm = date.getMonth() + 1;
    var yyyy = date.getFullYear();

    var ToDate = mm + '/' + dd + '/' + yyyy;
    var FromDate = mm + '/01/' + yyyy;
    $('#txtToDate').datepicker('setDate', ToDate);
    $('#txtFromDate').datepicker('setDate', FromDate);
}

Try dateutil, which has a tzlocal type that does what you need.

You do not need to use ORDER BY in inner query after WHERE clause because you have already used it in ROW_NUMBER() OVER (ORDER BY VRDATE DESC).

SELECT 
    * 
FROM (
    SELECT 
        Stockmain.VRNOA, 
        item.description as item_description, 
        party.name as party_name, 
        stockmain.vrdate, 
        stockdetail.qty, 
        stockdetail.rate, 
        stockdetail.amount, 
        ROW_NUMBER() OVER (ORDER BY VRDATE DESC) AS RowNum  --< ORDER BY
    FROM StockMain 
    INNER JOIN StockDetail 
        ON StockMain.stid = StockDetail.stid 
    INNER JOIN party 
        ON party.party_id = stockmain.party_id 
    INNER JOIN item 
        ON item.item_id = stockdetail.item_id 
    WHERE stockmain.etype='purchase' 
) AS MyDerivedTable
WHERE 
    MyDerivedTable.RowNum BETWEEN 1 and 5 

other way is:

sudo service apache2 reload
