They key thing to remember is 'origin' is not the value you may need to be using... it worked for me when I replaced 'origin' with repo's name.

Please <staticContent /> line and erased it from the web.config.

In Kotlin you just need to set your string value like this:

<string name="song_number_and_title">"%1$d ~ %2$s"</string>

Create a text view on your layout:

<TextView android:text="@string/song_number_and_title"/>

Then do this in your code if you using Anko:

val song = database.use { // get your song from the database }
song_number_and_title.setText(resources.getString(R.string.song_number_and_title, song.number, song.title))  

You might need to get your resources from the application context.

Tom's answer is quite detailed and exhaustive but you may also be interested in this simple study about Parquet vs Avro done at Allstate Insurance, summarized here:

"Overall, Parquet showed either similar or better results on every test [than Avro]. The query-performance differences on the larger datasets in Parquet’s favor are partly due to the compression results; when querying the wide dataset, Spark had to read 3.5x less data for Parquet than Avro. Avro did not perform well when processing the entire dataset, as suspected."

if I got it right, you can try

for item in [x for x in checklist if x not in mylist]:
    print (item)

You can try DBVisualizer some features are not free, but you can get an evaluate license...

It looks like you want the return keyword

def check_ping():
    hostname = "taylor"
    response = os.system("ping -c 1 " + hostname)
    # and then check the response...
    if response == 0:
        pingstatus = "Network Active"
    else:
        pingstatus = "Network Error"

    return pingstatus

You need to capture/'receive' the return value of the function(pingstatus) in a variable with something like:

pingstatus = check_ping()

NOTE: ping -c is for Linux, for Windows use ping -n

It's probably worth going through a good introductory tutorial to Python, which will cover all the fundamentals. I recommend investigating Udacity.com and codeacademy.com

If you have a SOCK_STREAM socket, recv just gets "up to the first 3000 bytes" from the stream. There is no clear guidance on how big to make the buffer: the only time you know how big a stream is, is when it's all done;-).

If you have a SOCK_DGRAM socket, and the datagram is larger than the buffer, recv fills the buffer with the first part of the datagram, returns -1, and sets errno to EMSGSIZE. Unfortunately, if the protocol is UDP, this means the rest of the datagram is lost -- part of why UDP is called an unreliable protocol (I know that there are reliable datagram protocols but they aren't very popular -- I couldn't name one in the TCP/IP family, despite knowing the latter pretty well;-).

To grow a buffer dynamically, allocate it initially with malloc and use realloc as needed. But that won't help you with recv from a UDP source, alas.

One way to get this error is trying to add a usercontrol to a form while the project is set to compile as x64. Visual Studio throws the unhelpful: "Failed to load toolbox item . It will be removed from the toolbox."

Workaround is to design with "Any CPU" and compile to x64 as necessary.

In iOS 5 there is a new and easy way to this. I'm not sure if the implementation is fully complete yet as it's not a gracious as, say, a UITableViewCell, but it should definitly do the trick as it is now standard supported in the iOS API. You will not need a private API for this.

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"This is an example alert!" delegate:self cancelButtonTitle:@"Hide" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
[alert release];

This renders an alertView like this (screenshot taken from the iPhone 5.0 simulator in XCode 4.2):

When pressing any buttons, the regular delegate methods will be called and you can extract the textInput there like so:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ 
    NSLog(@"Entered: %@",[[alertView textFieldAtIndex:0] text]);
}

Here I just NSLog the results that were entered. In production code, you should probably keep a pointer to your alertView as a global variable or use the alertView tag to check if the delegate function was called by the appropriate UIAlertView but for this example this should be okay.

You should check out the UIAlertView API and you'll see there are some more styles defined.

Hope this helped!

-- EDIT --

I was playing around with the alertView a little and I suppose it needs no announcement that it's perfectly possible to edit the textField as desired: you can create a reference to the UITextField and edit it as normal (programmatically). Doing this I constructed an alertView as you specified in your original question. Better late than never, right :-)?

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Please enter your name:" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeNumberPad;
alertTextField.placeholder = @"Enter your name";
[alert show];
[alert release];

This produces this alert:

You can use the same delegate method as I poster earlier to process the result from the input. I'm not sure if you can prevent the UIAlertView from dismissing though (there is no shouldDismiss delegate function AFAIK) so I suppose if the user input is invalid, you have to put up a new alert (or just reshow this one) until correct input was entered.

Have fun!

In addition to the answers above:

If you created/edited your .sh script file in Windows, make sure it was saved with line ending in Unix format. By default many editors in Windows will convert Unix line endings to Windows format and Linux will not recognize shebang (#!/bin/sh) at the beginning of the file. So Linux will produce the error message like if there is no shebang.

Tips:

• If you use Notepad++, you need to click "Edit/EOL Conversion/UNIX (LF)"
• If you use Visual Studio, I would suggest installing "End Of Line" plugin. Then you can make line endings visible by pressing Ctrl-R, Ctrl-W. And to set Linux style endings you can press Ctrl-R, Ctrl-L. For Windows style, press Ctrl-R, Ctrl-C.

Since aa is the set/object that might be null, can you check aa == null ?

(aa / xx might be interchangeable (a typo in the question); the original question talks about xx but only defines aa)

i.e.

select new {
    AssetID = x.AssetID,
    Status = aa == null ? (bool?)null : aa.Online; // a Nullable<bool>
}

or if you want the default to be false (not null):

select new {
    AssetID = x.AssetID,
    Status = aa == null ? false : aa.Online;
}

Update; in response to the downvote, I've investigated more... the fact is, this is the right approach! Here's an example on Northwind:

        using(var ctx = new DataClasses1DataContext())
        {
            ctx.Log = Console.Out;
            var qry = from boss in ctx.Employees
                      join grunt in ctx.Employees
                          on boss.EmployeeID equals grunt.ReportsTo into tree
                      from tmp in tree.DefaultIfEmpty()
                      select new
                             {
                                 ID = boss.EmployeeID,
                                 Name = tmp == null ? "" : tmp.FirstName
                        };
            foreach(var row in qry)
            {
                Console.WriteLine("{0}: {1}", row.ID, row.Name);
            }
        }

And here's the TSQL - pretty much what we want (it isn't ISNULL, but it is close enough):

SELECT [t0].[EmployeeID] AS [ID],
    (CASE
        WHEN [t2].[test] IS NULL THEN CONVERT(NVarChar(10),@p0)
        ELSE [t2].[FirstName]
     END) AS [Name]
FROM [dbo].[Employees] AS [t0]
LEFT OUTER JOIN (
    SELECT 1 AS [test], [t1].[FirstName], [t1].[ReportsTo]
    FROM [dbo].[Employees] AS [t1]
    ) AS [t2] ON ([t0].[EmployeeID]) = [t2].[ReportsTo]
-- @p0: Input NVarChar (Size = 0; Prec = 0; Scale = 0) []
-- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1

QED?

Expanding on the answer from Grin/Dan Abramov, this works across multiple input types. Tested in React >= 15.5

const inputTypes = [
    window.HTMLInputElement,
    window.HTMLSelectElement,
    window.HTMLTextAreaElement,
];

export const triggerInputChange = (node, value = '') => {

    // only process the change on elements we know have a value setter in their constructor
    if ( inputTypes.indexOf(node.__proto__.constructor) >-1 ) {

        const setValue = Object.getOwnPropertyDescriptor(node.__proto__, 'value').set;
        const event = new Event('input', { bubbles: true });

        setValue.call(node, value);
        node.dispatchEvent(event);

    }

};

Ted's answer is amazing. I ended up using a smaller version of that in case anyone is interested. Useful when you are looking for one aggregation that depends on values from multiple columns:

create a dataframe

df=pd.DataFrame({'a': [1,2,3,4,5,6], 'b': [1,1,0,1,1,0], 'c': ['x','x','y','y','z','z']})


   a  b  c
0  1  1  x
1  2  1  x
2  3  0  y
3  4  1  y
4  5  1  z
5  6  0  z

grouping and aggregating with apply (using multiple columns)

df.groupby('c').apply(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())

c
x    2.0
y    4.0
z    5.0

grouping and aggregating with aggregate (using multiple columns)

I like this approach since I can still use aggregate. Perhaps people will let me know why apply is needed for getting at multiple columns when doing aggregations on groups.

It seems obvious now, but as long as you don't select the column of interest directly after the groupby, you will have access to all the columns of the dataframe from within your aggregation function.

only access to the selected column

df.groupby('c')['a'].aggregate(lambda x: x[x>1].mean())

access to all columns since selection is after all the magic

df.groupby('c').aggregate(lambda x: x[(x['a']>1) & (x['b']==1)].mean())['a']

or similarly

df.groupby('c').aggregate(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())

I hope this helps.

As for extension methods, extension methods themselves are static; but they are invoked as if they are instance methods. Since a static class is not instantiable, you would never have an instance of the class to invoke an extension method from. For this reason the compiler does not allow extension methods to be defined for static classes.

Mr. Obnoxious wrote: "As any advanced .NET developer knows, new T() is slow because it generates a call to System.Activator which uses reflection to get the default constructor before calling it".

New() is compiled to the IL "newobj" instruction if the type is known at compile time. Newobj takes a constructor for direct invocation. Calls to System.Activator.CreateInstance() compile to the IL "call" instruction to invoke System.Activator.CreateInstance(). New() when used against generic types will result in a call to System.Activator.CreateInstance(). The post by Mr. Obnoxious was unclear on this point... and well, obnoxious.

This code:

System.Collections.ArrayList _al = new System.Collections.ArrayList();
System.Collections.ArrayList _al2 = (System.Collections.ArrayList)System.Activator.CreateInstance(typeof(System.Collections.ArrayList));

produces this IL:

  .locals init ([0] class [mscorlib]System.Collections.ArrayList _al,
           [1] class [mscorlib]System.Collections.ArrayList _al2)
  IL_0001:  newobj     instance void [mscorlib]System.Collections.ArrayList::.ctor()
  IL_0006:  stloc.0
  IL_0007:  ldtoken    [mscorlib]System.Collections.ArrayList

  IL_0011:  call       object [mscorlib]System.Activator::CreateInstance(class [mscorlib]System.Type)

This is a very interesting problem that Spring Security and Spring Web framework is not quite consistent in the way they handle the response. I believe it has to natively support error message handling with MessageConverter in a handy way.

I tried to find an elegant way to inject MessageConverter into Spring Security so that they could catch the exception and return them in a right format according to content negotiation. Still, my solution below is not elegant but at least make use of Spring code.

I assume you know how to include Jackson and JAXB library, otherwise there is no point to proceed. There are 3 Steps in total.

Step 1 - Create a standalone class, storing MessageConverters

This class plays no magic. It simply stores the message converters and a processor RequestResponseBodyMethodProcessor. The magic is inside that processor which will do all the job including content negotiation and converting the response body accordingly.

public class MessageProcessor { // Any name you like
    // List of HttpMessageConverter
    private List<HttpMessageConverter<?>> messageConverters;
    // under org.springframework.web.servlet.mvc.method.annotation
    private RequestResponseBodyMethodProcessor processor;

    /**
     * Below class name are copied from the framework.
     * (And yes, they are hard-coded, too)
     */
    private static final boolean jaxb2Present =
        ClassUtils.isPresent("javax.xml.bind.Binder", MessageProcessor.class.getClassLoader());

    private static final boolean jackson2Present =
        ClassUtils.isPresent("com.fasterxml.jackson.databind.ObjectMapper", MessageProcessor.class.getClassLoader()) &&
        ClassUtils.isPresent("com.fasterxml.jackson.core.JsonGenerator", MessageProcessor.class.getClassLoader());

    private static final boolean gsonPresent =
        ClassUtils.isPresent("com.google.gson.Gson", MessageProcessor.class.getClassLoader());

    public MessageProcessor() {
        this.messageConverters = new ArrayList<HttpMessageConverter<?>>();

        this.messageConverters.add(new ByteArrayHttpMessageConverter());
        this.messageConverters.add(new StringHttpMessageConverter());
        this.messageConverters.add(new ResourceHttpMessageConverter());
        this.messageConverters.add(new SourceHttpMessageConverter<Source>());
        this.messageConverters.add(new AllEncompassingFormHttpMessageConverter());

        if (jaxb2Present) {
            this.messageConverters.add(new Jaxb2RootElementHttpMessageConverter());
        }
        if (jackson2Present) {
            this.messageConverters.add(new MappingJackson2HttpMessageConverter());
        }
        else if (gsonPresent) {
            this.messageConverters.add(new GsonHttpMessageConverter());
        }

        processor = new RequestResponseBodyMethodProcessor(this.messageConverters);
    }

    /**
     * This method will convert the response body to the desire format.
     */
    public void handle(Object returnValue, HttpServletRequest request,
        HttpServletResponse response) throws Exception {
        ServletWebRequest nativeRequest = new ServletWebRequest(request, response);
        processor.handleReturnValue(returnValue, null, new ModelAndViewContainer(), nativeRequest);
    }

    /**
     * @return list of message converters
     */
    public List<HttpMessageConverter<?>> getMessageConverters() {
        return messageConverters;
    }
}

Step 2 - Create AuthenticationEntryPoint

As in many tutorials, this class is essential to implement custom error handling.

public class CustomEntryPoint implements AuthenticationEntryPoint {
    // The class from Step 1
    private MessageProcessor processor;

    public CustomEntryPoint() {
        // It is up to you to decide when to instantiate
        processor = new MessageProcessor();
    }

    @Override
    public void commence(HttpServletRequest request,
        HttpServletResponse response, AuthenticationException authException)
        throws IOException, ServletException {

        // This object is just like the model class, 
        // the processor will convert it to appropriate format in response body
        CustomExceptionObject returnValue = new CustomExceptionObject();
        try {
            processor.handle(returnValue, request, response);
        } catch (Exception e) {
            throw new ServletException();
        }
    }
}

Step 3 - Register the entry point

As mentioned, I do it with Java Config. I just show the relevant configuration here, there should be other configuration such as session stateless, etc.

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.exceptionHandling().authenticationEntryPoint(new CustomEntryPoint());
    }
}

Try with some authentication fail cases, remember the request header should include Accept : XXX and you should get the exception in JSON, XML or some other formats.

Take a look at anchor tags. You can create an anchor with

<div id="anchor-name">Heading Text</div>

and refer to it later with

<a href="http://server/page.html#anchor-name">Link text</a>

I had a similar scenario, and I thought that something like

str.replaceAll("\[|\]", "");

looked cleaner. Of course, if your token might have brackets in it, that wouldn't work.

Implementing Iterable interface allows an object to be the target of the "foreach" statement.

class SomeClass implements Iterable<String> {}

class Main 
{
  public void method()
  {
     SomeClass someClass = new SomeClass();
     .....

    for(String s : someClass) {
     //do something
    }
  }
}

Iterator is an interface, which has implementation for iterate over elements. Iterable is an interface which provides Iterator.

If you want to scan input fast without getting confused into Scanner class nextLine() method , Use Custom Input Scanner for it .

Code :

class ScanReader {
/**
* @author Nikunj Khokhar
*/
    private byte[] buf = new byte[4 * 1024];
    private int index;
    private BufferedInputStream in;
    private int total;

    public ScanReader(InputStream inputStream) {
        in = new BufferedInputStream(inputStream);
    }

    private int scan() throws IOException {
        if (index >= total) {
            index = 0;
            total = in.read(buf);
            if (total <= 0) return -1;
        }
        return buf[index++];
    }
    public char scanChar(){
        int c=scan();
        while (isWhiteSpace(c))c=scan();
        return (char)c;
    }


    public int scanInt() throws IOException {
        int integer = 0;
        int n = scan();
        while (isWhiteSpace(n)) n = scan();
        int neg = 1;
        if (n == '-') {
            neg = -1;
            n = scan();
        }
        while (!isWhiteSpace(n)) {
            if (n >= '0' && n <= '9') {
                integer *= 10;
                integer += n - '0';
                n = scan();
            }
        }
        return neg * integer;
    }

    public String scanString() throws IOException {
        int c = scan();
        while (isWhiteSpace(c)) c = scan();
        StringBuilder res = new StringBuilder();
        do {
            res.appendCodePoint(c);
            c = scan();
        } while (!isWhiteSpace(c));
        return res.toString();
    }

    private boolean isWhiteSpace(int n) {
        if (n == ' ' || n == '\n' || n == '\r' || n == '\t' || n == -1) return true;
        else return false;
    }

    public long scanLong() throws IOException {
        long integer = 0;
        int n = scan();
        while (isWhiteSpace(n)) n = scan();
        int neg = 1;
        if (n == '-') {
            neg = -1;
            n = scan();
        }
        while (!isWhiteSpace(n)) {
            if (n >= '0' && n <= '9') {
                integer *= 10;
                integer += n - '0';
                n = scan();
            }
        }
        return neg * integer;
    }

    public void scanLong(long[] A) throws IOException {
        for (int i = 0; i < A.length; i++) A[i] = scanLong();
    }

    public void scanInt(int[] A) throws IOException {
        for (int i = 0; i < A.length; i++) A[i] = scanInt();
    }

    public double scanDouble() throws IOException {
        int c = scan();
        while (isWhiteSpace(c)) c = scan();
        int sgn = 1;
        if (c == '-') {
            sgn = -1;
            c = scan();
        }
        double res = 0;
        while (!isWhiteSpace(c) && c != '.') {
            if (c == 'e' || c == 'E') {
                return res * Math.pow(10, scanInt());
            }
            res *= 10;
            res += c - '0';
            c = scan();
        }
        if (c == '.') {
            c = scan();
            double m = 1;
            while (!isWhiteSpace(c)) {
                if (c == 'e' || c == 'E') {
                    return res * Math.pow(10, scanInt());
                }
                m /= 10;
                res += (c - '0') * m;
                c = scan();
            }
        }
        return res * sgn;
    }

}

Advantages :

• Scans Input faster than BufferReader
• Reduces Time Complexity
• Flushes Buffer for every next input

Methods :

• scanChar() - scan single character
• scanInt() - scan Integer value
• scanLong() - scan Long value
• scanString() - scan String value
• scanDouble() - scan Double value
• scanInt(int[] array) - scans complete Array(Integer)
• scanLong(long[] array) - scans complete Array(Long)

Usage :

1. Copy the Given Code below your java code.
2. Initialise Object for Given Class

ScanReader sc = new ScanReader(System.in); 3. Import necessary Classes :

import java.io.BufferedInputStream; import java.io.IOException; import java.io.InputStream; 4. Throw IOException from your main method to handle Exception 5. Use Provided Methods. 6. Enjoy

Example :

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
class Main{
    public static void main(String... as) throws IOException{
        ScanReader sc = new ScanReader(System.in);
        int a=sc.scanInt();
        System.out.println(a);
    }
}
class ScanReader....

The error is coming as your query is getting formed as

SELECT * FROM Employ where number = parseInt(val);

I dont know which DB you are using but no DB will understand parseInt.

What you can do is use a variable say temp and store the value of parseInt(val) in temp variable and make the query as

SELECT * FROM Employ where number = temp;

in your CFG file please change the hibernate dialect

<!-- SQL dialect -->
    <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

Already @Abubakkar Rangara answered easy way to handle your problem

Alternative is :

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

For scanf, you need to use %hu since you're passing a pointer to an unsigned short. For printf, it's impossible to pass an unsigned short due to default promotions (it will be promoted to int or unsigned int depending on whether int has at least as many value bits as unsigned short or not) so %d or %u is fine. You're free to use %hu if you prefer, though.

I've read all answers, something very important is missing here, I'll KISS. There are 2 main reasons, why I need Self-Executing Anonymous Functions, or better said "Immediately-Invoked Function Expression (IIFE)":

1. Better namespace management (Avoiding Namespace Pollution -> JS Module)
2. Closures (Simulating Private Class Members, as known from OOP)

The first one has been explained very well. For the second one, please study following example:

var MyClosureObject = (function (){
  var MyName = 'Michael Jackson RIP';
  return {
    getMyName: function () { return MyName;},
    setMyName: function (name) { MyName = name}
  }
}());

Attention 1: We are not assigning a function to MyClosureObject, further more the result of invoking that function. Be aware of () in the last line.

Attention 2: What do you additionally have to know about functions in Javascript is that the inner functions get access to the parameters and variables of the functions, they are defined within.

Let us try some experiments:

I can get MyName using getMyName and it works:

 console.log(MyClosureObject.getMyName()); 
 // Michael Jackson RIP

The following ingenuous approach would not work:

console.log(MyClosureObject.MyName); 
// undefined

But I can set an another name and get the expected result:

MyClosureObject.setMyName('George Michael RIP');
console.log(MyClosureObject.getMyName()); 
// George Michael RIP

Edit: In the example above MyClosureObject is designed to be used without the newprefix, therefore by convention it should not be capitalized.

If there is not ISNULL() method, you can use this expression instead:

CASE WHEN fieldname IS NULL THEN 0 ELSE fieldname END

This works the same as ISNULL(fieldname, 0).

you can show the file selection dialog with a onclick function, and if a file is choosen (onchange event) then send the form to upload the file

 <form id='foto' method='post' action='upload' method="POST"  enctype="multipart/form-data" >
  <div style="height:0px;overflow:hidden"> 
  <input type="file" id="fileInput" name="fileInput" onchange="this.form.submit()"/> 
  </div>

  <i class='fa fa-camera' onclick="fileInput.click();"></i>
</form> 

The zip() function in Python 3 returns an iterator. That is the reason why when you print test1 you get - <zip object at 0x1007a06c8>. From documentation -

Make an iterator that aggregates elements from each of the iterables.

But once you do - list(test1) - you have exhausted the iterator. So after that anytime you do list(test1) would only result in empty list.

In case of test2, you have already created the list once, test2 is a list, and hence it will always be that list.

Inside your function for the click action use

$( "#tabs" ).tabs({ active: # });

Where # is replaced by the tab index you want to select.

Edit: change from selected to active, selected is deprecated

Didn't see this method in answers, so here it is:

"0".repeat( 200 ).split("").map( parseFloat )

In result you will get zero-valued array of length 200:

[ 0, 0, 0, 0, ... 0 ]

I'm not sure about the performance of this code, but it shouldn't be an issue if you use it for relatively small arrays.

A single line of code using Linq

public static bool IsPalindrome(string str)  
{
    return str.SequenceEqual(str.Reverse());
}

Try this:

scp /home/ubuntu/myfile C:\users\Anshul\Desktop

Adding what worked for me in case others have the same issue and end up here. I had an older project that had the CLANG_ENABLE_MODULES setting set to No. After hours of frustration I compared to a working project and found I had Enable Modules Set to no under my LLVM build settings. Setting this to Yes solved my problem and the app builds fine.

Project Settings -> Build Settings -> search for 'Modules' and Update Enable Modules (C and Objective-C) to YES.

You could also use stringstream.

It should be noted that math.floor() always rounds down, and therefore does not yield a sensible result for negative floating point values.

For example, -10.4 represented as an integer would usually be either truncated or rounded to -10. Yet the result of math.floor() is not the same:

math.floor(-10.4) => -11

For truncation with type conversion, the following helper function will work:

function tointeger( x )
    num = tonumber( x )
    return num < 0 and math.ceil( num ) or math.floor( num )
end

I did a little experiment to see which of these methods

• string.startswith('hello')
• string.rfind('hello') == 0
• string.rpartition('hello')[0] == ''
• string.rindex('hello') == 0

are most efficient to return whether a certain string begins with another string.

Here is the result of one of the many test runs I've made, where each list is ordered to show the least time it took (in seconds) to parse 5 million of each of the above expressions during each iteration of the while loop I used:

I believe that it is pretty obvious from the start that the startswith method would come out the most efficient, as returning whether a string begins with the specified string is its main purpose.

What surprises me is that the seemingly impractical string.rpartition('hello')[0] == '' method always finds a way to be listed first, before the string.startswith('hello') method, every now and then. The results show that using str.partition to determine if a string starts with another string is more efficient then using both rfind and rindex.

Another thing I've noticed is that string.rindex('hello') == 0 and string.rindex('hello') == 0 have a good battle going on, each rising from fourth to third place, and dropping from third to fourth place, which makes sense, as their main purposes are the same.

Here is the code:

from time import perf_counter

string = 'hello world'
places = dict()

while True:
    start = perf_counter()
    for _ in range(5000000):
        string.startswith('hello')
    end = perf_counter()
    places['startswith'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rfind('hello') == 0
    end = perf_counter()
    places['rfind'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rpartition('hello')[0] == ''
    end = perf_counter()
    places['rpartition'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rindex('hello') == 0
    end = perf_counter()
    places['rindex'] = round(end - start, 2)
    
    print([f'{b}: {str(a).ljust(4, "4")}' for a, b in sorted(i[::-1] for i in places.items())])

Use orderBy:

df.orderBy('column_name', ascending=False)

Complete answer:

group_by_dataframe.count().filter("`count` >= 10").orderBy('count', ascending=False)

Don't forget to seed the RNG with srand() first.

Decision tree:

1. Frameworks like Qt and SWT need native DLLs. So you have to ask yourself: Are all necessary platforms supported? Can you package the native DLLs with your app?

   See here, how to do this for SWT.

   If you have a choice here, you should prefer Qt over SWT. Qt has been developed by people who understand UI and the desktop while SWT has been developed out of necessity to make Eclipse faster. It's more a performance patch for Java 1.4 than a UI framework. Without JFace, you're missing many major UI components or very important features of UI components (like filtering on tables).

   If SWT is missing a feature that you need, the framework is somewhat hostile to extending it. For example, you can't extend any class in it (the classes aren't final, they just throw exceptions when the package of this.getClass() isn't org.eclipse.swt and you can't add new classes in that package because it's signed).

2. If you need a native, pure Java solution, that leaves you with the rest. Let's start with AWT, Swing, SwingX - the Swing way.

   AWT is outdated. Swing is outdated (maybe less so but not much work has been done on Swing for the past 10 years). You could argue that Swing was good to begin with but we all know that code rots. And that's especially true for UIs today.

   That leaves you with SwingX. After a longer period of slow progress, development has picked up again. The major drawback with Swing is that it hangs on to some old ideas which very kind of bleeding edge 15 years ago but which feel "clumsy" today. For example, the table views do support filtering and sorting but you still have to configure this. You'll have to write a lot of boiler plate code just to get a decent UI that feels modern.

   Another weak area is theming. As of today, there are a lot of themes around. See here for a top 10. But some are slow, some are buggy, some are incomplete. I hate it when I write a UI and users complain that something doesn't work for them because they selected an odd theme.

3. JGoodies is another layer on top of Swing, like SwingX. It tries to make Swing more pleasant to use. The web site looks great. Let's have a look at the tutorial ... hm ... still searching ... hang on. It seems that there is no documentation on the web site at all. Google to the rescue. Nope, no useful tutorials at all.

   I'm not feeling confident with a UI framework that tries so hard to hide the documentation from potential new fans. That doesn't mean JGoodies is bad; I just couldn't find anything good to say about it but that it looks nice.

4. JavaFX. Great, stylish. Support is there but I feel it's more of a shiny toy than a serious UI framework. This feeling roots in the lack of complex UI components like tree tables. There is a webkit-based component to display HTML.

   When it was introduced, my first thought was "five years too late." If your aim is a nice app for phones or web sites, good. If your aim is professional desktop application, make sure it delivers what you need.

5. Pivot. First time I heard about it. It's basically a new UI framework based on Java2D. So I gave it a try yesterday. No Swing, just tiny bit of AWT (new Font(...)).

   My first impression was a nice one. There is an extensive documentation that helps you getting started. Most of the examples come with live demos (Note: You must have Java enabled in your web browser; this is a security risk) in the web page, so you can see the code and the resulting application side by side.

   In my experience, more effort goes into code than into documentation. By looking at the Pivot docs, a lot of effort must have went into the code. Note that there is currently a bug which prevents some of the examples to work (PIVOT-858) in your browser.

   My second impression of Pivot is that it's easy to use. When I ran into a problem, I could usually solve it quickly by looking at an example. I'm missing a reference of all the styles which each component supports, though.

   As with JavaFX, it's missing some higher level components like a tree table component (PIVOT-306). I didn't try lazy loading with the table view. My impression is that if the underlying model uses lazy loading, then that's enough.

   Promising. If you can, give it a try.

Just keep the following in mind.

In IIS if you have a folder for example called Pages with multiple websites in it. Website will inherit settings from the web.config file from the parent directory. So even if the folder page (in this example Pages) isn't a website but contains a web.config file, all websites listed inside of it will inherit the setting.

Rather than running any particular command, I would recommend running brew doctor and taking all warnings seriously. There may be other problems you get stuck at which may not be captured in this question.

Also, as brew gets updated with time, particular commands may or may not remain valid. brew doctor, however, will ensure that you get up to date troubleshooting.

The most convenient way according to me is:

(Val in X[:, col_num])

where Val is the value that you want to check for and X is the array. In your example, suppose you want to check if the value 8 exists in your the third column. Simply write

(8 in X[:, 2])

This will return True if 8 is there in the third column, else False.

The $ symbol simply invokes the jQuery library's selector functionality. So $("#Text") returns the jQuery object for the Text div which can then be modified.

Although this entry is quite old and most of you probably already know, I think it's worth mention that GWT 2.x includes a new compile flag which speeds up compiles by skipping optimizations. You definitely shouldn't deploy JavaScript compiled that way, but it can be a time saver during non-production continuous builds.

Just include the flag: -draftCompile to your GWT compiler line.

I was also having the trouble to route to a different view using navlink.

My implementation was as follows and works perfectly;

<NavLink tag='li'>
  <div
    onClick={() =>
      this.props.history.push('/admin/my- settings')
    }
  >
    <DropdownItem className='nav-item'>
      Settings
    </DropdownItem>
  </div>
</NavLink>

Wrap it with a div, assign the onClick handler to the div. Use the history object to push a new view.

In my case, the culprit was not distinguish the main and test sources folder within pom.xml (generated by eclipse maven project)

<build>
    <sourceDirectory>src</sourceDirectory>
    ....
</build>

If you override default source folder settings in pom file, you must explicitly set the main AND test source folders!!!!

<build>
    <sourceDirectory>src/main/java</sourceDirectory>
    <testSourceDirectory>src/test/java</testSourceDirectory>
    ....
</build>

you can convert a string to array with str_split and use foreach

$chars = str_split($str);
foreach($chars as $char){
    // your code
}

I'm not sure what format you're looking for in your difference but here's how to do it using DateTime

$datetime1 = new DateTime();
$datetime2 = new DateTime('2011-01-03 17:13:00');
$interval = $datetime1->diff($datetime2);
$elapsed = $interval->format('%y years %m months %a days %h hours %i minutes %s seconds');
echo $elapsed;

Here you have an example of two ways of doing a vertical alignment. I use them and they work pretty well. One is using absolute positioning and the other using flexbox.

Vertical Align Example

Using flexbox, you can align an element by itself inside another element with display: flex; using align-self. If you need to align it also horizontally, you can use align-items and justify-content in the container.

If you don't want to use flexbox, you can use the position property. If you make the container relative and the content absolute, the content will be able to move freely inside the container. So if you use top: 0; and left: 0; in the content, it will be positioned at the top left corner of the container.

Then, to align it, you just need to change the top and left references to 50%. This will position the content at the container center from the top left corner of the content.

So you need to correct this translating the content half its size to the left and top.

Ideally, there should only be two scenarios of when an iOS application would need to accept an un-trusted certificate.

Scenario A: You are connected to a test environment which is using a self-signed certificate.

Scenario B: You are Proxying HTTPS traffic using a MITM Proxy like Burp Suite, Fiddler, OWASP ZAP, etc. The Proxies will return a certificate signed by a self-signed CA so that the proxy is able to capture HTTPS traffic.

Production hosts should never use un-trusted certificates for obvious reasons.

If you need to have the iOS simulator accept an un-trusted certificate for testing purposes it is highly recommended that you do not change application logic in order disable the built in certificate validation provided by the NSURLConnection APIs. If the application is released to the public without removing this logic, it will be susceptible to man-in-the-middle attacks.

The recommended way to accept un-trusted certificates for testing purposes is to import the Certificate Authority(CA) certificate which signed the certificate onto your iOS Simulator or iOS device. I wrote up a quick blog post which demonstrates how to do this which an iOS Simulator at:

accepting untrusted certificates using the ios simulator

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

If your only requirement is to print the third field of every line, with each field delimited by a comma, you can use cut:

cut -d, -f3 file

• -d, sets the delimiter to a comma
• -f3 specifies that only the third field is to be printed

Life is simple if you get a good web framework. Web services in Django are easy. Define your model, write view functions that return your CSV documents. Skip the templates.

For MVC developers, to redirect a browser using javascript:

window.location.href = "@Url.Action("Action", "Controller")";

I know this is not possible for alert(), so I guess it is not possible for confirm either. Reason is security: it is not allowed for you to change it so you wouldn't present yourself as some system process or something.

Your getElementById is looking for an element with id "myclass", but in your html the id of the DIV is showhide. Change to:

<script>
function changeclass() {

var NAME = document.getElementById("showhide")

NAME.className="mynewclass"

} 
</script>

Unless you are trying to target a different element with the id "myclass", then you need to make sure such an element exists.

A component cannot update its own props unless they are arrays or objects (having a component update its own props even if possible is an anti-pattern), but can update its state and the props of its children.

For instance, a Dashboard has a speed field in its state, and passes it to a Gauge child thats displays this speed. Its render method is just return <Gauge speed={this.state.speed} />. When the Dashboard calls this.setState({speed: this.state.speed + 1}), the Gauge is re-rendered with the new value for speed.

Just before this happens, Gauge's componentWillReceiveProps is called, so that the Gauge has a chance to compare the new value to the old one.

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

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

Follow this step by step process for manual deletion of topics

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

you can read this doc .this concept is well explained here http://developer.android.com/training/basics/fragments/communicating.html

My way to do this job is:

char to int
char var;
cout<<(int)var-48;
    
int to char
int var;
cout<<(char)(var|48);

And I write these functions for conversions:

int char2int(char *szBroj){
    int counter=0;
    int results=0;
    while(1){
        if(szBroj[counter]=='\0'){
            break;
        }else{
            results*=10;
            results+=(int)szBroj[counter]-48;
            counter++;
        }
    }
    return results;
}

char * int2char(int iNumber){
    int iNumbersCount=0;
    int iTmpNum=iNumber;
    while(iTmpNum){
        iTmpNum/=10;
        iNumbersCount++;
    }
    char *buffer=new char[iNumbersCount+1];
    for(int i=iNumbersCount-1;i>=0;i--){
        buffer[i]=(char)((iNumber%10)|48);
        iNumber/=10;
    }
    buffer[iNumbersCount]='\0';
    return buffer;
}

Yep, you'll want to do something like this:

echo -n "Enter Fullname: " 
read fullname

Another option would be to have them supply this information on the command line. Getopts is your best bet there.

Using getopts in bash shell script to get long and short command line options

Yes you can:

Use this method to prevent errors:

<script> 
query=location.hash;
document.cookie= 'anchor'+query;
</script>

And of course in PHP, explode that puppy and get one of the values

$split = explode('/', $_COOKIE['anchor']);
print_r($split[1]); //to test it, use print_r. this line will print the value after the anchortag

You need to add 2 methods, note __hash__ and __eq__:

class MyThing:
    def __init__(self,name,location,length):
        self.name = name
        self.location = location
        self.length = length

    def __hash__(self):
        return hash((self.name, self.location))

    def __eq__(self, other):
        return (self.name, self.location) == (other.name, other.location)

    def __ne__(self, other):
        # Not strictly necessary, but to avoid having both x==y and x!=y
        # True at the same time
        return not(self == other)

The Python dict documentation defines these requirements on key objects, i.e. they must be hashable.

Late to the party, but I think it is a useful answer.

flatMap would be the shortest way to do it.

Stream.of(objects).flatMap(o->(o instanceof Client)?Stream.of((Client)o):Stream.empty())

If o is a Client then create a Stream with a single element, otherwise use the empty stream. These streams will then be flattened into a Stream<Client>.

The original conio.h was implemented by Borland, so its not a part of the C Standard Library nor is defined by POSIX.

But here is an implementation for Linux that uses ncurses to do the job.

If you use the nextLine() method immediately following the nextInt() method, nextInt() reads integer tokens; because of this, the last newline character for that line of integer input is still queued in the input buffer and the next nextLine() will be reading the remainder of the integer line (which is empty). So we read can read the empty space to another string might work. Check below code.

import java.util.Scanner;

public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        int i = scan.nextInt();
        Double d = scan.nextDouble();
        String f = scan.nextLine();
        String s = scan.nextLine();


        // Write your code here.

        System.out.println("String: " + s);
        System.out.println("Double: " + d);
         System.out.println("Int: " + i);
    }
}

In the case of my Cordova-project, uninstalling and installing cordova -g fixed the problem for me.

npm uninstall -g cordova
npm install -g cordova

As everyone else here has stated: You cannot upload just any file automatically with JavaScript.

HOWEVER! If you have access to the information you want to send in your code (i.e., not C:\passwords.txt), then you can upload it as a blob-type, and then treat it as a file.

What the server will end up seeing will be indistinguishable from someone actually setting the value of <input type="file" />. The trick, ultimately, is to begin a new XMLHttpRequest() with the server...

function uploadFile (data) {
        // define data and connections
    var blob = new Blob([JSON.stringify(data)]);
    var url = URL.createObjectURL(blob);
    var xhr = new XMLHttpRequest();
    xhr.open('POST', 'myForm.php', true);
    
        // define new form
    var formData = new FormData();
    formData.append('someUploadIdentifier', blob, 'someFileName.json');
        
        // action after uploading happens
    xhr.onload = function(e) {
        console.log("File uploading completed!");
    };
    
        // do the uploading
    console.log("File uploading started!");
    xhr.send(formData);
}

    // This data/text below is local to the JS script, so we are allowed to send it!
uploadFile({'hello!':'how are you?'});

So, what could you possibly use this for? I use it for uploading HTML5 canvas elements as jpg's. This saves the user the trouble of having to open a file input element, only to select the local, cached image that they just resized, modified, etc.. But it should work for any file type.

Here's a nice fun LINQ example.

public static byte[] StringToByteArray(string hex) {
    return Enumerable.Range(0, hex.Length)
                     .Where(x => x % 2 == 0)
                     .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                     .ToArray();
}

Use > and < for 'greater-than' and 'less-than' respectively

During maven compilation you can skip test execution by adding following plugin in pom.xml

<plugin>

    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.20.1</version>
    <configuration>

    </configuration>
</plugin>

Swift 2.0 Compability

func listWithFilter () {

    let fileManager = NSFileManager.defaultManager()
           // We need just to get the documents folder url
    let documentsUrl = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as NSURL

    do {
    // if you want to filter the directory contents you can do like this:
    if let directoryUrls = try? NSFileManager.defaultManager().contentsOfDirectoryAtURL(documentsUrl, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions.SkipsSubdirectoryDescendants) {
        print(directoryUrls)
       ........
        }

    }

}

OR

 func listFiles() -> [String] {

    var theError = NSErrorPointer()
    let dirs = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true) as? [String]
    if dirs != nil {
        let dir = dirs![0]
        do {
        let fileList = try NSFileManager.defaultManager().contentsOfDirectoryAtPath(dir)
        return fileList as [String]
        }catch {

        }

    }else{
        let fileList = [""]
        return fileList
    }
    let fileList = [""]
    return fileList

}

If updating cURL doesn't fix it, updating NSS should do the trick.

I suppose you want to get the content generated by PHP, if so use:

$Vdata = file_get_contents('http://YOUR_HOST/YOUR/FILE.php');

Otherwise if you want to get the source code of the PHP file, it's the same as a .txt file:

$Vdata = file_get_contents('path/to/YOUR/FILE.php');

You can do

orig.update(extra)

or, if you don't want orig to be modified, make a copy first:

dest = dict(orig)  # or orig.copy()
dest.update(extra)

Note that if extra and orig have overlapping keys, the final value will be taken from extra. For example,

>>> d1 = {1: 1, 2: 2}
>>> d2 = {2: 'ha!', 3: 3}
>>> d1.update(d2)
>>> d1
{1: 1, 2: 'ha!', 3: 3}

Java implementations typically use a two-step compilation process. Java source code is compiled down to bytecode by the Java compiler. The bytecode is executed by a Java Virtual Machine (JVM). Modern JVMs use a technique called Just-in-Time (JIT) compilation to compile the bytecode to native instructions understood by hardware CPU on the fly at runtime.

Some implementations of JVM may choose to interpret the bytecode instead of JIT compiling it to machine code, and running it directly. While this is still considered an "interpreter," It's quite different from interpreters that read and execute the high level source code (i.e. in this case, Java source code is not interpreted directly, the bytecode, output of Java compiler, is.)

It is technically possible to compile Java down to native code ahead-of-time and run the resulting binary. It is also possible to interpret the Java code directly.

To summarize, depending on the execution environment, bytecode can be:

• compiled ahead of time and executed as native code (similar to most C++ compilers)
• compiled just-in-time and executed
• interpreted
• directly executed by a supported processor (bytecode is the native instruction set of some CPUs)

Had the exact same error in a procedure. It turns out the user running it (a technical user in our case) did not have sufficient rigths to create a temporary table.

EXEC sp_addrolemember 'db_ddladmin', 'username_here';

did the trick

You can use an ActionFilterAttribute

public class BasicAuthAttribute : ActionFilterAttribute
{
    public string BasicRealm { get; set; }
    protected NetworkCredential Nc { get; set; }

    public BasicAuthAttribute(string user,string pass)
    {
        this.Nc = new NetworkCredential(user,pass);
    }

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var req = filterContext.HttpContext.Request;
        var auth = req.Headers["Authorization"].ToString();
        if (!String.IsNullOrEmpty(auth))
        {
            var cred = System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(auth.Substring(6)))
                .Split(':');
            var user = new {Name = cred[0], Pass = cred[1]};
            if (user.Name == Nc.UserName && user.Pass == Nc.Password) return;
        }

        filterContext.HttpContext.Response.Headers.Add("WWW-Authenticate",
            String.Format("Basic realm=\"{0}\"", BasicRealm ?? "Ryadel"));
        filterContext.Result = new UnauthorizedResult();
    }
}

and add the attribute to your controller

[BasicAuth("USR", "MyPassword")]

It works with params if you capture an array with one element, that holds the current index.

int[] idx = { 0 };
params.forEach(e -> query.bind(idx[0]++, e));

The above code assumes, that the method forEach iterates through the elements in encounter order. The interface Iterable specifies this behaviour for all classes unless otherwise documented. Apparently it works for all implementations of Iterable from the standard library, and changing this behaviour in the future would break backward-compatibility.

If you are working with Streams instead of Collections/Iterables, you should use forEachOrdered, because forEach can be executed concurrently and the elements can occur in different order. The following code works for both sequential and parallel streams:

int[] idx = { 0 };
params.stream().forEachOrdered(e -> query.bind(idx[0]++, e));

If your running php5 you can use:

$url = 'http://www.example.com';
print_r(get_headers($url, 1));

Alternatively with php4 a user has contributed the following:

/**
This is a modified version of code from "stuart at sixletterwords dot com", at 14-Sep-2005 04:52. This version tries to emulate get_headers() function at PHP4. I think it works fairly well, and is simple. It is not the best emulation available, but it works.

Features:
- supports (and requires) full URLs.
- supports changing of default port in URL.
- stops downloading from socket as soon as end-of-headers is detected.

Limitations:
- only gets the root URL (see line with "GET / HTTP/1.1").
- don't support HTTPS (nor the default HTTPS port).
*/

if(!function_exists('get_headers'))
{
    function get_headers($url,$format=0)
    {
        $url=parse_url($url);
        $end = "\r\n\r\n";
        $fp = fsockopen($url['host'], (empty($url['port'])?80:$url['port']), $errno, $errstr, 30);
        if ($fp)
        {
            $out  = "GET / HTTP/1.1\r\n";
            $out .= "Host: ".$url['host']."\r\n";
            $out .= "Connection: Close\r\n\r\n";
            $var  = '';
            fwrite($fp, $out);
            while (!feof($fp))
            {
                $var.=fgets($fp, 1280);
                if(strpos($var,$end))
                    break;
            }
            fclose($fp);

            $var=preg_replace("/\r\n\r\n.*\$/",'',$var);
            $var=explode("\r\n",$var);
            if($format)
            {
                foreach($var as $i)
                {
                    if(preg_match('/^([a-zA-Z -]+): +(.*)$/',$i,$parts))
                        $v[$parts[1]]=$parts[2];
                }
                return $v;
            }
            else
                return $var;
        }
    }
}

Both would have a result similar to:

Array
(
    [0] => HTTP/1.1 200 OK
    [Date] => Sat, 29 May 2004 12:28:14 GMT
    [Server] => Apache/1.3.27 (Unix)  (Red-Hat/Linux)
    [Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT
    [ETag] => "3f80f-1b6-3e1cb03b"
    [Accept-Ranges] => bytes
    [Content-Length] => 438
    [Connection] => close
    [Content-Type] => text/html
)

Therefore you could just check to see that the header response was OK eg:

$headers = get_headers($url, 1);
if ($headers[0] == 'HTTP/1.1 200 OK') {
//valid 
}

if ($headers[0] == 'HTTP/1.1 301 Moved Permanently') {
//moved or redirect page
}

W3C Codes and Definitions

Here is a simple and very inelegant & potentially dangerous way.

1. Backup DB
2. Detach DB
3. Rename Log file
4. Attach DB
5. New log file will be recreated
6. Delete Renamed Log file.

I'm guessing that you are not doing log backups. (Which truncate the log). My advice is to change recovery model from full to simple. This will prevent log bloat.

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted:

import elementtree.ElementTree as ET

tree = ET.parse("test.xml")
doc = tree.getroot()
thingy = doc.find('timeSeries')

print thingy.attrib

and got the following back:

{'name': 'NWIS Time Series Instantaneous Values'}

It appears to have found the timeSeries element without needing to use numerical indices.

What would be useful now is knowing what you mean when you say "it doesn't work." Since it works for me given the same input, it is unlikely that ElementTree is broken in some obvious way. Update your question with any error messages, backtraces, or anything you can provide to help us help you.

Assigning a value to a local variable and then returning that at the end is considered a good practice. Methods having multiple exits are harder to debug and can be difficult to read.

That said, thats the only plus point left to this paradigm. It was originated when only low-level procedural languages were around. And it made much more sense at that time.

While we are on the topic you must check this out. Its an interesting read.

Try this way:

message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]"));
String address = "[email protected],[email protected]";
InternetAddress[] iAdressArray = InternetAddress.parse(address);
message.setRecipients(Message.RecipientType.CC, iAdressArray);

This worked for me, just put it into any layout you want to.

<FrameLayout
    android:layout_width="32dp"
    android:layout_height="192dp">

    <SeekBar
        android:layout_width="192dp"
        android:layout_height="32dp"
        android:layout_gravity="center"
        android:rotation="270" />

</FrameLayout>

What you could do is also to take the next token as a String, converts this string to a char array and test that each character in the array is a digit.

I think that's correct, if you don't want to deal with the exceptions.

You can't.

So just don't apply styles directly like that, and apply a class "foo", and then define that in your CSS specification:

a.foo { color : orange; }
a.foo:hover { font-weight : bold; }

I found a super simple explanation about class << self , Eigenclass and different type of methods.

In Ruby, there are three types of methods that can be applied to a class:

1. Instance methods
2. Singleton methods
3. Class methods

Instance methods and class methods are almost similar to their homonymous in other programming languages.

class Foo  
  def an_instance_method  
    puts "I am an instance method"  
  end  
  def self.a_class_method  
    puts "I am a class method"  
  end  
end

foo = Foo.new

def foo.a_singleton_method
  puts "I am a singletone method"
end

Another way of accessing an Eigenclass(which includes singleton methods) is with the following syntax (class <<):

foo = Foo.new

class << foo
  def a_singleton_method
    puts "I am a singleton method"
  end
end

now you can define a singleton method for self which is the class Foo itself in this context:

class Foo
  class << self
    def a_singleton_and_class_method
      puts "I am a singleton method for self and a class method for Foo"
    end
  end
end

I took the content above and changed it around a bit. I like positive logic first, and I thought a HashSet might give better performance than some other options, like searching through a String. Although, I'm not sure if the autoboxing penalty is worth it, but if the compiler optimizes for ASCII chars, then the cost of boxing will be low.

/***
 * Replaces any character not specifically unreserved to an equivalent 
 * percent sequence.
 * @param s
 * @return
 */
public static String encodeURIcomponent(String s)
{
    StringBuilder o = new StringBuilder();
    for (char ch : s.toCharArray()) {
        if (isSafe(ch)) {
            o.append(ch);
        }
        else {
            o.append('%');
            o.append(toHex(ch / 16));
            o.append(toHex(ch % 16));
        }
    }
    return o.toString();
}

private static char toHex(int ch)
{
    return (char)(ch < 10 ? '0' + ch : 'A' + ch - 10);
}

// https://tools.ietf.org/html/rfc3986#section-2.3
public static final HashSet<Character> UnreservedChars = new HashSet<Character>(Arrays.asList(
        'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z',
        'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z',
        '0','1','2','3','4','5','6','7','8','9',
        '-','_','.','~'));
public static boolean isSafe(char ch)
{
    return UnreservedChars.contains(ch);
}

You need to use view INFORMATION_SCHEMA.COLUMNS

select COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = my_table_name AND COLUMN_NAME like 'a%'

TO inline rows you can use PIVOT and for execution EXEC() function.

What is a singleton :
It is a class which only allows one instance of itself to be created, and usually gives simple access to that instance.

When should you use :
It depends on the situation.

Note : please do not use on db connection, for a detailed answer please refer to the answer of @Chad Grant

Here is a simple example of a Singleton:

public sealed class Singleton
{
    private static readonly Singleton instance = new Singleton();

    // Explicit static constructor to tell C# compiler
    // not to mark type as beforefieldinit
    static Singleton()
    {
    }

    private Singleton()
    {
    }

    public static Singleton Instance
    {
        get
        {
            return instance;
        }
    }
}

You can also use Lazy<T> to create your Singleton.

See here for a more detailed example using Lazy<T>

Run your code with the -tt option to find out if you are using tabs and spaces inconsistently

3rd approach is most common way to share data between components. you may inject the item service which you want to use in related component.

import { Injectable } from '@angular/core';
import { Predicate } from '../interfaces'

import * as _ from 'lodash';

@Injectable()
export class ItemsService {

    constructor() { }


    removeItemFromArray<T>(array: Array<T>, item: any) {
        _.remove(array, function (current) {
            //console.log(current);
            return JSON.stringify(current) === JSON.stringify(item);
        });
    }

    removeItems<T>(array: Array<T>, predicate: Predicate<T>) {
        _.remove(array, predicate);
    }

    setItem<T>(array: Array<T>, predicate: Predicate<T>, item: T) {
        var _oldItem = _.find(array, predicate);
        if(_oldItem){
            var index = _.indexOf(array, _oldItem);
            array.splice(index, 1, item);
        } else {
            array.push(item);
        }
    }


    addItemToStart<T>(array: Array<T>, item: any) {
        array.splice(0, 0, item);
    }


    getPropertyValues<T, R>(array: Array<T>, property : string) : R
    {
        var result = _.map(array, property);
        return <R><any>result;
    }

    getSerialized<T>(arg: any): T {
        return <T>JSON.parse(JSON.stringify(arg));
    }
}



export interface Predicate<T> {
    (item: T): boolean
}

I came up with the same problem, and I work it out !

        <img :src='book.images.small' v-on:mouseenter="hoverImg">

Elaborating on @Jonathan Ray I think this does the trick a bit better

import time
import inspect

def timed(f:callable):
    start = time.time()
    ret = f()
    elapsed = 1000*(time.time() - start)
    source_code=inspect.getsource(f).strip('\n') 
    logger.info(source_code+":  "+str(elapsed)+" seconds")
    return ret

It allows to take a regular line of code, say a = np.sin(np.pi) and transform it rather simply into

a = timed(lambda: np.sin(np.pi))

so that the timing is printed onto the logger and you can keep the same assignment of the result to a variable you might need for further work.

I suppose in Python 3.8 one could use the := but I do not have 3.8 yet

If you want to create a file and write and append data to it many times, then use the below code, it will create file if not exits and will append data if it exists.

 SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
        Date now = new Date();
        String fileName = formatter.format(now) + ".txt";//like 2016_01_12.txt


         try
            {
                File root = new File(Environment.getExternalStorageDirectory()+File.separator+"Music_Folder", "Report Files");
                //File root = new File(Environment.getExternalStorageDirectory(), "Notes");
                if (!root.exists()) 
                {
                    root.mkdirs();
                }
                File gpxfile = new File(root, fileName);


                FileWriter writer = new FileWriter(gpxfile,true);
                writer.append(sBody+"\n\n");
                writer.flush();
                writer.close();

            }
            catch(IOException e)
            {

From a purely "make it fit in the div" perspective, add the following to your table class (jsfiddle):

table-layout: fixed;
width: 100%;

Set your column widths as desired; otherwise, the fixed layout algorithm will distribute the table width evenly across your columns.

For quick reference, here are the table layout algorithms, emphasis mine:

• Fixed (source)

  With this (fast) algorithm, the horizontal layout of the table does not depend on the contents of the cells; it only depends on the table's width, the width of the columns, and borders or cell spacing.

• Automatic (source)

  In this algorithm (which generally requires no more than two passes), the table's width is given by the width of its columns [, as determined by content] (and intervening borders).
  
  [...] This algorithm may be inefficient since it requires the user agent to have access to all the content in the table before determining the final layout and may demand more than one pass.

Click through to the source documentation to see the specifics for each algorithm.

All the selector crap api doesn't work as expected. After trying all the solutions presented in this thread to no good, we just solved the problem at the moment of inflating the ListView Item.

1. Make sure your item keeps it's state, we did it as a member variable of the MenuItem (boolean selected)

2. When you inflate, ask if the underlying item is selected, if so, just set the drawable resource that you want as the background (be it a 9patch or whatever). Make sure your adapter is aware of this and that it calls notifyDataChanged() when something has been selected.

       @Override
   public View getView(int position, View convertView, ViewGroup parent) {
       View rowView = convertView;
       if (rowView == null) {
           LayoutInflater inflater = act.getLayoutInflater();
           rowView = inflater.inflate(R.layout.slidemenu_listitem, null);
           MenuItemHolder viewHolder = new MenuItemHolder();
           viewHolder.label = (TextView) rowView.findViewById(R.id.slidemenu_item_label);
           viewHolder.icon = (ImageView) rowView.findViewById(R.id.slidemenu_item_icon);
           rowView.setTag(viewHolder);
       }
   
       MenuItemHolder holder = (MenuItemHolder) rowView.getTag();
       String s = items[position].label;
       holder.label.setText(s);
       holder.icon.setImageDrawable(items[position].icon);
   
       //Here comes the magic
       rowView.setSelected(items[position].selected);
   
       rowView.setBackgroundResource((rowView.isSelected()) ? R.drawable.slidemenu_item_background_selected : R.drawable.slidemenu_item_background);
   
       return rowView;
   }
   

It'd be really nice if the selectors would actually work, in theory it's a nice and elegant solution, but it seems like it's broken. KISS.

A Table can have a Composite Primary Key which is a primary key made from two or more columns. For example:

CREATE TABLE userdata (
  userid INT,
  userdataid INT,
  info char(200),
  primary key (userid, userdataid)
);

Update: Here is a link with a more detailed description of composite primary keys.

In addition to what is listed above, I had to enable both TCP and UDP ports for SQLExpress to connect remotely. Because I have three different instances on my development machine, I enable 1430-1435 for both TCP and UDP.

In general we have default-initialization in first case and value-initialization in second case.

For example: in case with int (POD type):

• int* test = new int - we have any initialization and value of *test can be any.

• int* test = new int() - *test will have 0 value.

next behaviour depended from your type Test. We have defferent cases: Test have defult constructor, Test have generated default constructor, Test contain POD member, non POD member...

Change Minute parameter to 0.

You can set the cron for every three hours as:

0 */3 * * * your command here ..

In case you encounter the error and some important data cannot be discarded on the running redis instance (problems with permissions for the rdb file or its directory incorrectly, or running out of disk space), you can always redirect the rdb file to be written somewhere else.

Using redis-cli, you can do something like this:

CONFIG SET dir /tmp/some/directory/other/than/var
CONFIG SET dbfilename temp.rdb

After this, you might want to execute a BGSAVE command to make sure that the data will be written to the rdb file. Make sure that when you execute INFO persistence, bgsave_in_progress is already 0 and rdb_last_bgsave_status is ok. After that, you can now start backing up the generated rdb file somewhere safe.

handleChange({target}) {
    const files = target.files
    target.value = ''
}

You can override by enabling Password less authentication. But you should install keys (pub, priv) before going for that.

Execute the following commands at local server.

Local $> ssh-keygen -t rsa 

Press ENTER for all options prompted. No values need to be typed.

Local $> cd .ssh
Local $> scp .ssh/id_rsa.pub user@targetmachine:
Prompts for pwd$>  ENTERPASSWORD

Connect to remote server using the following command

Local $> ssh user@targetmachine
Prompts for pwd$> ENTERPASSWORD

Execute the following commands at remote server

Remote $> mkdir .ssh
Remote $> chmod 700 .ssh
Remote $> cat id_rsa.pub >> .ssh/authorized_keys
Remote $> chmod 600 .ssh/authorized_keys
Remote $> exit

Execute the following command at local server to test password-less authentication. It should be connected without password.

$> ssh user@targetmachine

I think I know what you are asking for. Here is what you can do.

first get the height of the person say h meters.

if you can calculate the height of the camera from ground (using height if the person i.e. h) and get angles A and B using gyroscope or something from android then you can calculate the height of the object using the above formula.

Isn't this what you were looking for???

let me know if you need any explanation.

Use the getResourceAsStream() method on the ServletContext object, e.g.

servletContext.getResourceAsStream("/WEB-INF/myfile");

How you get a reference to the ServletContext depends on your application... do you want to do it from a Servlet or from a JSP?

EDITED: If you're inside a Servlet object, then call getServletContext(). If you're in JSP, use the predefined variable application.

UNI: For UNIQUE:

• It is a set of one or more columns of a table to uniquely identify the record.
• A table can have multiple UNIQUE key.
• It is quite like primary key to allow unique values but can accept one null value which primary key does not.

PRI: For PRIMARY:

• It is also a set of one or more columns of a table to uniquely identify the record.
• A table can have only one PRIMARY key.
• It is quite like UNIQUE key to allow unique values but does not allow any null value.

MUL: For MULTIPLE:

• It is also a set of one or more columns of a table which does not identify the record uniquely.
• A table can have more than one MULTIPLE key.
• It can be created in table on index or foreign key adding, it does not allow null value.
• It allows duplicate entries in column.
• If we do not specify MUL column type then it is quite like a normal column but can allow null entries too hence; to restrict such entries we need to specify it.
• If we add indexes on column or add foreign key then automatically MUL key type added.

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

Generated Column is one of the good approach for MySql version which is 5.7.6 and above.

There are two kinds of Generated Columns:

• Virtual (default) - column will be calculated on the fly when a record is read from a table
• Stored - column will be calculated when a new record is written/updated in the table

Both types can have NOT NULL restrictions, but only a stored Generated Column can be a part of an index.

For current case, we are going to use stored generated column. To implement I have considered that both of the values required for calculation are present in table

CREATE TABLE order_details (price DOUBLE, quantity INT, amount DOUBLE AS (price * quantity));

INSERT INTO order_details (price, quantity) VALUES(100,1),(300,4),(60,8);

amount will automatically pop up in table and you can access it directly, also please note that whenever you will update any of the columns, amount will also get updated.

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

See this fiddle.
Basically, you want to get the values of your option-tags, but you always try to get the value of your select-node with $("#first").val().

So we have to select the option-tags and we will utilize jQuerys selectors:

$("#first option").each(function() {
    console.log($(this).val());
});

$("#first option") selects every option which is a child of the element with the id first.

in your constructor you are creating another int array:

 public Date(){
  int[] data = {0,0,0};
  }

Try this:

 data = {0,0,0};

NOTE: By the way you do NOT need to initialize your array elements if it is declared as an instance variable. Instance variables automatically get their default values, which for an integer array, the default values are all zeroes.

If you had locally declared array though they you would need to initialize each element.

Here is a solution using the javax.crypto library and the apache commons codec library for encoding and decoding in Base64 that I was looking for:

import java.security.spec.KeySpec;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import org.apache.commons.codec.binary.Base64;

public class TrippleDes {

    private static final String UNICODE_FORMAT = "UTF8";
    public static final String DESEDE_ENCRYPTION_SCHEME = "DESede";
    private KeySpec ks;
    private SecretKeyFactory skf;
    private Cipher cipher;
    byte[] arrayBytes;
    private String myEncryptionKey;
    private String myEncryptionScheme;
    SecretKey key;

    public TrippleDes() throws Exception {
        myEncryptionKey = "ThisIsSpartaThisIsSparta";
        myEncryptionScheme = DESEDE_ENCRYPTION_SCHEME;
        arrayBytes = myEncryptionKey.getBytes(UNICODE_FORMAT);
        ks = new DESedeKeySpec(arrayBytes);
        skf = SecretKeyFactory.getInstance(myEncryptionScheme);
        cipher = Cipher.getInstance(myEncryptionScheme);
        key = skf.generateSecret(ks);
    }


    public String encrypt(String unencryptedString) {
        String encryptedString = null;
        try {
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] plainText = unencryptedString.getBytes(UNICODE_FORMAT);
            byte[] encryptedText = cipher.doFinal(plainText);
            encryptedString = new String(Base64.encodeBase64(encryptedText));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return encryptedString;
    }


    public String decrypt(String encryptedString) {
        String decryptedText=null;
        try {
            cipher.init(Cipher.DECRYPT_MODE, key);
            byte[] encryptedText = Base64.decodeBase64(encryptedString);
            byte[] plainText = cipher.doFinal(encryptedText);
            decryptedText= new String(plainText);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return decryptedText;
    }


    public static void main(String args []) throws Exception
    {
        TrippleDes td= new TrippleDes();

        String target="imparator";
        String encrypted=td.encrypt(target);
        String decrypted=td.decrypt(encrypted);

        System.out.println("String To Encrypt: "+ target);
        System.out.println("Encrypted String:" + encrypted);
        System.out.println("Decrypted String:" + decrypted);

    }

}

Running the above program results with the following output:

String To Encrypt: imparator
Encrypted String:FdBNaYWfjpWN9eYghMpbRA==
Decrypted String:imparator

As it turns out, the problem wasn't actually a looping chain of synonyms, but the fact that the synonym was pointing to a view that did not exist.

Oracle apparently errors out as a looping chain in this condition.

First, do not use DataOutputStream unless it’s really necessary. Second:

Socket socket = new Socket("host", port);
OutputStream socketOutputStream = socket.getOutputStream();
socketOutputStream.write(message);

Of course this lacks any error checking but this should get you going. The JDK API Javadoc is your friend and can help you a lot.

Lightsail VPSs are bundles of existing AWS products, offered through a significantly simplified interface. The difference is that Lightsail offers you a limited and fixed menu of options but with much greater ease of use. Other than the narrower scope of Lightsail in order to meet the requirements for simplicity and low cost, the underlying technology is the same.

The pre-defined bundles can be described:

% aws lightsail --region us-east-1 get-bundles
{
    "bundles": [
        {
            "name": "Nano",
            "power": 300,
            "price": 5.0,
            "ramSizeInGb": 0.5,
            "diskSizeInGb": 20,
            "transferPerMonthInGb": 1000,
            "cpuCount": 1,
            "instanceType": "t2.nano",
            "isActive": true,
            "bundleId": "nano_1_0"
        },
        ...
    ]
}

It's worth reading through the Amazon EC2 T2 Instances documentation, particularly the CPU Credits section which describes the base and burst performance characteristics of the underlying instances.

Importantly, since your Lightsail instances run in VPC, you still have access to the full spectrum of AWS services, e.g. S3, RDS, and so on, as you would from any EC2 instance.

For those using Vue CLI 3 and the webpack-simple install, Aaron's answer did work for me however I wasn't keen on adding my environment variables to my webpack.config.js as I wanted to commit it to GitHub. Instead I installed the dotenv-webpack plugin and this appears to load environment variables fine from a .env file at the root of the project without the need to prepend VUE_APP_ to the environment variables.

You have to use Kendo UI DropDownList select method (documentation in here).

Basically you should:

// get a reference to the dropdown list
var dropdownlist = $("#Instrument").data("kendoDropDownList");

If you know the index you can use:

// selects by index
dropdownlist.select(1);

If not, use:

// selects item if its text is equal to "test" using predicate function
dropdownlist.select(function(dataItem) {
    return dataItem.symbol === "test";
});

JSFiddle example here

Just pick up the TDM-GCC 64x package. (It constains both the 32 and 64 bit versions of the MinGW toolchain and comes within a neat installer.) More importantly, it contains something called the "winpthread" library.

It comprises of the pthread.h header, libwinpthread.a, libwinpthread.dll.a static libraries for both 32-bit and 64-bit and the required .dlls libwinpthread-1.dll and libwinpthread_64-1.dll(this, as of 01-06-2016).

You'll need to link to the libwinpthread.a library during build. Other than that, your code can be the same as for native Pthread code on Linux. I've so far successfully used it to compile a few basic Pthread programs in 64-bit on windows.

Alternatively, you can use the following library which wraps the windows threading API into the pthreads API: pthreads-win32.

The above two seem to be the most well known ways for this.

Hope this helps.

A generic solution like so

public static <X, Y, Z> Map<X, Z> transform(Map<X, Y> input,
        Function<Y, Z> function) {
    return input
            .entrySet()
            .stream()
            .collect(
                    Collectors.toMap((entry) -> entry.getKey(),
                            (entry) -> function.apply(entry.getValue())));
}

Example

Map<String, String> input = new HashMap<String, String>();
input.put("string1", "42");
input.put("string2", "41");
Map<String, Integer> output = transform(input,
            (val) -> Integer.parseInt(val));

If there is no ORDER BY clause, then TOP 100 PERCENT is redundant. (As you mention, this was the 'trick' with views)

[Hopefully the optimizer will optimize this away.]

Another easy flexible approach to display block at center: using native text alignment with line-height and text-align.

Solution:

.parent {
    line-height: 100vh;        
    text-align: center;
}

.child {
    display: inline-block;
    vertical-align: middle;
    line-height: 100%;
}

And html sample:

<div class="parent">
  <div class="child">My center block</div>
</div>

We make div.parent fullscreen, and his single child div.child align as text with display: inline-block.

Advantages:

• flexebility, no absolute values
• support resize
• works fine on mobile

As pointed by this the best way to obtain a concurrency-able HashSet is by means of Collections.synchronizedSet()

Set s = Collections.synchronizedSet(new HashSet(...));

This worked for me and I haven't seen anybody really pointing to it.

EDIT This is less efficient than the currently aproved solution, as Eugene points out, since it just wraps your set into a synchronized decorator, while a ConcurrentHashMap actually implements low-level concurrency and it can back your Set just as fine. So thanks to Mr. Stepanenkov for making that clear.

http://docs.oracle.com/javase/8/docs/api/java/util/Collections.html#synchronizedSet-java.util.Set-

More modern syntax:

git diff ..master path/to/file

The double-dot prefix means "from the current working directory to". You can also say:

• master.., i.e. the reverse of above. This is the same as master.
• mybranch..master, explicitly referencing a state other than the current working tree.
• v2.0.1..master, i.e. referencing a tag.
• [refspec]..[refspec], basically anything identifiable as a code state to git.

Think it's too late to answer but... :) in case of path with volume name you could write something like this:

using System;
using System.Linq;
using System.IO;

// ...

var drives = Environment.GetLogicalDrives();
var invalidChars = Regex.Replace(new string(Path.GetInvalidFileNameChars()), "[\\\\/]", "");
var drive = drives.FirstOrDefault(d => filePath.StartsWith(d));
if (drive != null) {
    var fileDirPath = filePath.Substring(drive.Length);
    if (0 < fileDirPath.Length) {
        if (fileDirPath.IndexOfAny(invalidChars.ToCharArray()) == -1) {
            if (Path.Combine(drive, fileDirPath) != drive) {
                // path correct and we can proceed
            }
        }
    }
}

Another valid option is to spread the joins across multiple LINQ clauses, as follows:

public static IEnumerable<Announcementboard> GetSiteContent(string pageName, DateTime date)
{
    IEnumerable<Announcementboard> content = null;
    IEnumerable<Announcementboard> addMoreContent = null;
        try
        {
            content = from c in DB.Announcementboards
              // Can be displayed beginning on this date
              where c.Displayondate > date.AddDays(-1)
              // Doesn't Expire or Expires at future date
              && (c.Displaythrudate == null || c.Displaythrudate > date)
              // Content is NOT draft, and IS published
              && c.Isdraft == "N" && c.Publishedon != null
              orderby c.Sortorder ascending, c.Heading ascending
              select c;

            // Get the content specific to page names
            if (!string.IsNullOrEmpty(pageName))
            {
              addMoreContent = from c in content
                  join p in DB.Announceonpages on c.Announcementid equals p.Announcementid
                  join s in DB.Apppagenames on p.Apppagenameid equals s.Apppagenameid
                  where s.Apppageref.ToLower() == pageName.ToLower()
                  select c;
            }

            // Add the specified content using UNION
            content = content.Union(addMoreContent);

            // Exclude the duplicates using DISTINCT
            content = content.Distinct();

            return content;
        }
    catch (MyLovelyException ex)
    {
        // Add your exception handling here
        throw ex;
    }
}

Actually you don't need "install" or "compile" anything before using Boost in your project. You can just download and extract the Boost library to any location on your machine, which is usually like /usr/local/.

When you compile your code, you can just indicate the compiler where to find the libraries by -I. For example, g++ -I /usr/local/boost_1_59_0 xxx.hpp.

To sum up if your remote is called origin and you're working on master branch:

git tag -d <tagname>
git push origin :refs/tags/<tagname>
git tag <tagname> <commitId>
git push origin <tagname>

• Line 1 removes the tag in local env.
• Line 2 removes the tag in remote env.
• Line 3 adds the tag to different commit
• Line 4 pushes the change to the remote

You can also exchange line 4 to git push origin --tags to push all the changes with tags from your local changes.

Basing on @stuart-golodetz, @greg-hewgill, @eedeep, @ben-hocking answers, comments below their answers and NateS comments below my answer.

I've written this extensions class for an app perhaps 6 years ago, and have been using it ever since in many solutions without issues. Hope it helps.

edit: I noticed some might not know how to use an extension class.

To use this extension class, just reference its namespace in your class by adding the following line using joinext;

^ this should allow you to to see the intellisense of extension functions on any IEnumerable object collection you happen to use.

Hope this helps. Let me know if it's still not clear, and I'll hopefully write a sample example on how to use it.

Now here is the class:

namespace joinext
{    
public static class JoinExtensions
    {
        public static IEnumerable<TResult> FullOuterJoin<TOuter, TInner, TKey, TResult>(
            this IEnumerable<TOuter> outer,
            IEnumerable<TInner> inner,
            Func<TOuter, TKey> outerKeySelector,
            Func<TInner, TKey> innerKeySelector,
            Func<TOuter, TInner, TResult> resultSelector)
            where TInner : class
            where TOuter : class
        {
            var innerLookup = inner.ToLookup(innerKeySelector);
            var outerLookup = outer.ToLookup(outerKeySelector);

            var innerJoinItems = inner
                .Where(innerItem => !outerLookup.Contains(innerKeySelector(innerItem)))
                .Select(innerItem => resultSelector(null, innerItem));

            return outer
                .SelectMany(outerItem =>
                {
                    var innerItems = innerLookup[outerKeySelector(outerItem)];

                    return innerItems.Any() ? innerItems : new TInner[] { null };
                }, resultSelector)
                .Concat(innerJoinItems);
        }


        public static IEnumerable<TResult> LeftJoin<TOuter, TInner, TKey, TResult>(
            this IEnumerable<TOuter> outer,
            IEnumerable<TInner> inner,
            Func<TOuter, TKey> outerKeySelector,
            Func<TInner, TKey> innerKeySelector,
            Func<TOuter, TInner, TResult> resultSelector)
        {
            return outer.GroupJoin(
                inner,
                outerKeySelector,
                innerKeySelector,
                (o, i) =>
                    new { o = o, i = i.DefaultIfEmpty() })
                    .SelectMany(m => m.i.Select(inn =>
                        resultSelector(m.o, inn)
                        ));

        }



        public static IEnumerable<TResult> RightJoin<TOuter, TInner, TKey, TResult>(
            this IEnumerable<TOuter> outer,
            IEnumerable<TInner> inner,
            Func<TOuter, TKey> outerKeySelector,
            Func<TInner, TKey> innerKeySelector,
            Func<TOuter, TInner, TResult> resultSelector)
        {
            return inner.GroupJoin(
                outer,
                innerKeySelector,
                outerKeySelector,
                (i, o) =>
                    new { i = i, o = o.DefaultIfEmpty() })
                    .SelectMany(m => m.o.Select(outt =>
                        resultSelector(outt, m.i)
                        ));

        }

    }
}

There is an API for unsigned Integer and Long in Java 8!

The cleanest way is to not (directly) use an iterator at all:

• type your map with generics
• use a foreach loop to iterate over the entries:

Like this:

Map<Integer, String> hm = new HashMap<Integer, String>();

hm.put(0, "zero");
hm.put(1, "one");

for (Map.Entry<Integer, String> entry : hm.entrySet()) {
    // do something with the entry
    System.out.println(entry.getKey() + " - " + entry.getValue());
    // the getters are typed:
    Integer key = entry.getKey();
    String value = entry.getValue();
}

This is way more efficient than iterating over keys, because you avoid n calls to get(key).

It's good practise to extend from a baseController and implement some base functions implement a function to check if the user instance is null like this if the user form the Userinterface then there is no user logged in

/**

*/
class BaseController extends AbstractController
{

    /**
     * @return User

     */
    protected function getUser(): ?User
    {
        return parent::getUser();
    }

    /**
     * @return bool
     */
    protected function isUserLoggedIn(): bool
    {
        return $this->getUser() instanceof User;
    }
}

In cmd you can use the following:

c:\your directory\your folder\build>java -jar yourFile.jar 

However, you need to create you .jar file on your project if you use Netbeans. How just go to Run ->Clean and Build Project(your project name)

Also make sure you project properties Build->Packing has a yourFile.jar and check Build JAR after Compiling check Copy Depentent Libraries

Warning: Make sure your Environmental variables for Java are properly set.

Old way to compile and run a Java File from the command prompt (cmd)

Compiling: c:\>javac Myclass.java
Running: c:\>java com.myPackage.Myclass

I hope this info help.

Your question is not very clear but this should achieve what you are trying to do:

decimal numericValue = 3494309432324.00m;
string formatted = numericValue.ToString("#,##0.00");

Then formatted will contain: 3,494,309,432,324.00

All these answers with .ReadAllBytes(). Another, similar (I won't say duplicate, since they were trying to refactor their code) question was asked on SO here: Best way to read a large file into a byte array in C#?

A comment was made on one of the posts regarding .ReadAllBytes():

File.ReadAllBytes throws OutOfMemoryException with big files (tested with 630 MB file 
and it failed) – juanjo.arana Mar 13 '13 at 1:31

A better approach, to me, would be something like this, with BinaryReader:

public static byte[] FileToByteArray(string fileName)
{
    byte[] fileData = null;

    using (FileStream fs = File.OpenRead(fileName)) 
    { 
        var binaryReader = new BinaryReader(fs); 
        fileData = binaryReader.ReadBytes((int)fs.Length); 
    }
    return fileData;
}

But that's just me...

Of course, this all assumes you have the memory to handle the byte[] once it is read in, and I didn't put in the File.Exists check to ensure the file is there before proceeding, as you'd do that before calling this code.

Subclass UILabel, and override -drawInRect:

In my case, I got the image URL before getting to the display component and want to use it as the background image so to use that URL I have to tell Angular that it's safe and can be used.

In .ts file

userImage: SafeStyle;
ngOnInit(){
    this.userImage = this.sanitizer.bypassSecurityTrustStyle('url(' + sessionStorage.getItem("IMAGE") + ')');
}

In .html file

<div mat-card-avatar class="nav-header-image" [style.background-image]="userImage"></div>

There are already good, detailed answers here, but no visual examples, so here's a quick illustration:

<div>This is a div.</div>_x000D_
<div>This is a div.</div>_x000D_
<div>This is a div.</div>_x000D_
<span>This is a span.</span>_x000D_
<span>This is a span.</span>_x000D_
<span>This is a span.</span>

<div> is a block tag, while <span> is an inline tag.

Beyond historical (good and already reported) reasons, there's is also a little problem with operators precedence: dot operator has higher priority than star operator, so if you have struct containing pointer to struct containing pointer to struct... These two are equivalent:

(*(*(*a).b).c).d

a->b->c->d

But the second is clearly more readable. Arrow operator has the highest priority (just as dot) and associates left to right. I think this is clearer than use dot operator both for pointers to struct and struct, because we know the type from the expression without have to look at the declaration, that could even be in another file.

For Laravel 5.3 and above

Check Scott's answer below.

For Laravel 5 up to 5.2

Simply put,

On auth middleware:

// redirect the user to "/login"
// and stores the url being accessed on session
if (Auth::guest()) {
    return redirect()->guest('login');
}
return $next($request);

On login action:

// redirect the user back to the intended page
// or defaultpage if there isn't one
if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return redirect()->intended('defaultpage');
}

For Laravel 4 (old answer)

At the time of this answer there was no official support from the framework itself. Nowadays you can use the method pointed out by bgdrl below this method: (I've tried updating his answer, but it seems he won't accept)

On auth filter:

// redirect the user to "/login"
// and stores the url being accessed on session
Route::filter('auth', function() {
    if (Auth::guest()) {
        return Redirect::guest('login');
    }
});

On login action:

// redirect the user back to the intended page
// or defaultpage if there isn't one
if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return Redirect::intended('defaultpage');
}

For Laravel 3 (even older answer)

You could implement it like this:

Route::filter('auth', function() {
    // If there's no user authenticated session
    if (Auth::guest()) {
        // Stores current url on session and redirect to login page
        Session::put('redirect', URL::full());
        return Redirect::to('/login');
    }
    if ($redirect = Session::get('redirect')) {
        Session::forget('redirect');
        return Redirect::to($redirect);
    }
});

// on controller
public function get_login()
{
    $this->layout->nest('content', 'auth.login'); 
}

public function post_login()
{
    $credentials = [
        'username' => Input::get('email'),
        'password' => Input::get('password')
    ];

    if (Auth::attempt($credentials)) {
        return Redirect::to('logged_in_homepage_here');
    }

    return Redirect::to('login')->with_input();
}

Storing the redirection on Session has the benefit of persisting it even if the user miss typed his credentials or he doesn't have an account and has to signup.

This also allows for anything else besides Auth to set a redirect on session and it will work magically.

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

The MySQL dependency should be like the following syntax in the pom.xml file.

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.21</version>
    </dependency>

Make sure the syntax, groupId, artifactId, Version has included in the dependancy.

In my opinion this is a design flaw of pytz library. It should be more reliable to specify a timezone using the offset, e.g.

pytz.construct("UTC-07:00")

which gives you Canada/Pacific timezone.

You really can't. PHP is generated at the server then sent to the browser, where JS starts to do it's stuff. So, whatever happens in JS on a page, PHP doesn't know because it's already done it's stuff. @manjula is correct, that if you want that to happen, you'd have to use a POST, or an ajax.

it should work fine:

var Something = $(this).children("td:nth-child(n)").text();

If you go through the official tutorial of angularjs https://docs.angularjs.org/tutorial/step_07

Note: Starting with AngularJS version 1.2, ngRoute is in its own module and must be loaded by loading the additional angular-route.js file, which we download via Bower above.

Also please note from ngRoute api https://docs.angularjs.org/api/ngRoute

Installation First include angular-route.js in your HTML:

You can download this file from the following places:

Google CDN e.g. //ajax.googleapis.com/ajax/libs/angularjs/X.Y.Z/angular-route.js Bower e.g. bower install [email protected] code.angularjs.org e.g. "//code.angularjs.org/X.Y.Z/angular-route.js" where X.Y.Z is the AngularJS version you are running.

Then load the module in your application by adding it as a dependent module:

angular.module('app', ['ngRoute']); With that you're ready to get started!

Also, using the StringBuilder.AppendLine method.

C++11 allows you to do:

for (const auto& kv : myMap) {
    std::cout << kv.first << " has value " << kv.second << std::endl;
}

C++17 allows you to do:

for (const auto& [key, value] : myMap) {
    std::cout << key << " has value " << value << std::endl;
}

using structured binding.

UPDATE:

const auto is safer if you don't want to modify the map.

Try this instead.

If a download fails for some reason Maven will not try to download it within a certain time frame (it leaves a file with a timestamp).

To fix this you can either

• Clear (parts of) your .m2 repo
• Run maven with -U to force an update

There is also the approach of organizing the folders not by the structure of the framework, but by the structure of the application's function. There is a github starter Angular/Express application that illustrates this called angular-app.

Definitely in Modules.

• Sheets can be deleted, copied and moved with surprising results.
• You can't call code in sheet "code-behind" from other modules without fully qualifying the reference. This will lead to coupling of the sheet and the code in other modules/sheets.
• Modules can be exported and imported into other workbooks, and put under version control
• Code in split logically into modules (data access, utilities, spreadsheet formatting etc.) can be reused as units, and are easier to manage if your macros get large.

Since the tooling is so poor in primitive systems such as Excel VBA, best practices, obsessive code hygiene and religious following of conventions are important, especially if you're trying to do anything remotely complex with it.

This article explains the intended usages of different types of code containers. It doesn't qualify why these distinctions should be made, but I believe most developers trying to develop serious applications on the Excel platform follow them.

There's also a list of VBA coding conventions I've found helpful, although they're not directly related to Excel VBA. Please ignore the crazy naming conventions they have on that site, it's all crazy hungarian.

There are several file versions on the great Christoph Gohlke's site.

Something I have found important when installing wheels from this site is to first run this from the Python console:

import pip
print(pip.pep425tags.get_supported())

so that you know which version you should install for your computer. Picking the wrong version may fail the installing of the package (especially if you don't use the right CPython tag, for example, cp27).

I tried a couple of solution but I thing easy way like this (you are in the local folder):

#!/bin/bash
git fetch

var_local=`cat .git/refs/heads/master`
var_remote=`git log origin/master -1 | head -n1 | cut -d" " -f2`

if [ "$var_remote" = "$var_local" ]; then
    echo "Strings are equal." #1
else
    echo "Strings are not equal." #0 if you want
fi

Then you did compare local git and remote git last commit number....

1. Open your PHP folder.
2. Find php.ini-development and open it.
3. Find ;extension=mysqli
4. delete the ; symbol
5. save file and change the file extension from php.ini-development to php.ini
6. Restart the server and test the code:

    if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {  
            echo 'We don\'t have mysqli!!!';  
     } else {  
         echo 'mysqli is installed';
     }

7. if it not working, change both extension_dir in php.ini from "ext" to "c:\php\ext" and extension=mysqli to extension=php_mysqli.dll then test again Remember to reset the server every time you test

The php option mysql.connect_timeout is the reason for this. It's not only used for connect timeout, but as well as waiting for the first answer from the server. You can increase it like this:

ini_set('mysql.connect_timeout', 300);
ini_set('default_socket_timeout', 300); 

INSERT INTO prices(group, id, price)
SELECT 7, articleId, 1.50
FROM article where name like 'ABC%';

What is the point of the exercise?

As people pointed out already, you could have a non-generic function taking the largest item, and compiler will automatically convert up smaller ints for you.

static bool IntegerFunction(Int64 value) { }

If your function is on performance-critical path (very unlikely, IMO), you could provide overloads for all needed functions.

static bool IntegerFunction(Int64 value) { }
...
static bool IntegerFunction(Int16 value) { }

If you are using the Dart plugin, go to Android Studio, menu File -> Settings. And search for "reformat code with", click "Reformat code with dartfmt" under the main menu:

Click "Add keyboard Shortcut". Then press Ctrl + Alt + L and the shortcut should work (If Ctrl + Alt + L make the computer sleep/suspend, change the shortcut in your system settings to something else. Otherwise, both shortcuts will collide).

The 2 in Anaconda2 means that the main version of Python will be 2.x rather than the 3.x installed in Anaconda3. The current release has Python 2.7.13.

The 4.4.0.1 is the version number of Anaconda. The current advertised version is 4.4.0 and I assume the .1 is a minor release or for other similar use. The Windows releases, which I use, just say 4.4.0 in the file name.

Others have now explained the difference between Anaconda and Miniconda, so I'll skip that.

I would recommend the following solutions:

without lib fun:

    value = (value*value)/value

(The above does not actually work.)

with lib fun:

   value = Math.abs(value);

You might try having that delete job operate by first inserting the key of each row to be deleted into a temp table like this pseudocode

create temporary table deletetemp (userid int);

insert into deletetemp (userid)
  select userid from onlineusers where datetime <= now - interval 900 second;

delete from onlineusers where userid in (select userid from deletetemp);

Breaking it up like this is less efficient but it avoids the need to hold a key-range lock during the delete.

Also, modify your select queries to add a where clause excluding rows older than 900 seconds. This avoids the dependency on the cron job and allows you to reschedule it to run less often.

Theory about the deadlocks: I don't have a lot of background in MySQL but here goes... The delete is going to hold a key-range lock for datetime, to prevent rows matching its where clause from being added in the middle of the transaction, and as it finds rows to delete it will attempt to acquire a lock on each page it is modifying. The insert is going to acquire a lock on the page it is inserting into, and then attempt to acquire the key lock. Normally the insert will wait patiently for that key lock to open up but this will deadlock if the delete tries to lock the same page the insert is using because thedelete needs that page lock and the insert needs that key lock. This doesn't seem right for inserts though, the delete and insert are using datetime ranges that don't overlap so maybe something else is going on.

For Windows (7), the same folder is located at,

%APPDATA%\Subversion\auth

Type in the above in the Run(Win key + R) dialog box and hit Enter,

To check the existing username open the below file as a text file,

%APPDATA%\Subversion\auth\svn.simple\xxxxxxxxxx

This is only an add-on to the accepted answer:

def get_results(db_cursor):
    desc = [d[0] for d in db_cursor.description]
    results = [dotdict(dict(zip(desc, res))) for res in db_cursor.fetchall()]
    return results

where dotdict is:

class dotdict(dict):
    __getattr__ = dict.get
    __setattr__ = dict.__setitem__
    __delattr__ = dict.__delitem__

This will allow you to access much easier the values by column names.
Suppose you have a user table with columns name and email:

cursor.execute('select * from users')
results = get_results(cursor)
for res in results:
  print(res.name, res.email)

Thanks for your feed back got it to work I used the sshpass tool.

Limit the length of characters in a regular expression? ^[a-z]{6,15}$'

Limit length of characters or Numbers in a regular expression? ^[a-z | 0-9]{6,15}$'

Most solutions above combine illegal chars for both path and filename which is wrong (even when both calls currently return the same set of chars). I would first split the path+filename in path and filename, then apply the appropriate set to either if them and then combine the two again.

Your code contains two problems:

• The equality operator in JavaScript is ==, not =.
• jQuery.text() joins all text nodes of matched elements into a single string. If you have two successive elements, of which the first contains 'some' and the second contains 'Text', then your code will incorrectly think that there exists an element that contains 'someText'.

I suggest the following instead:

if ($('#field > div.field-item:contains("someText")').length > 0) {
    $("#somediv").addClass("thisClass");
}

playSound is a static method meaning it exists when the program is loaded. audioSounds and minTime are SoundManager instance variable, meaning they will exist within an instance of SoundManager. You have not created an instance of SoundManager so audioSounds doesn't exist (or it does but you do not have a reference to a SoundManager object to see that).

To solve your problem you can either make audioSounds static:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

so they will be created and may be referenced in the same way that PlaySound will be. Alternatively you can create an instance of SoundManager from within your method:

SoundManager soundManager = new SoundManager();
foreach (AudioSource sound in soundManager.audioSounds) // Loop through List with foreach
{
    if (sourceSound.name != sound.name && sound.time <= soundManager.minTime)
    {
        playsound = true;
    }
}

Since you add .. after cmake, it will jump up and up (just like cd ..) in the directory. But if you want to run cmake under the same folder with CMakeLists.txt, please use . instead of ...

With Java8, non heap region no more contains PermGen but Metaspace, which is a major change in Java8, supposed to get rid of out of memory errors with java as metaspace size can be increased depending on the space required by jvm for class data.

If you're still wondering how to solve it.

I use

$protected $dates = ['created_at','updated_at','aired'];

In my model and in my where i do

where('aired','>=',time())

So just use the unix to compaire in where.

In views on the otherhand you have to use the date object.

Hope it helps someone!

To add some info that helped me today, a jQuery object/this can also be passed in to the .not() selector.

$(document).ready(function(){_x000D_
    $(".navitem").click(function(){_x000D_
        $(".navitem").removeClass("active");_x000D_
        $(".navitem").not($(this)).addClass("active");_x000D_
    });_x000D_
});

.navitem_x000D_
{_x000D_
    width: 100px;_x000D_
    background: red;_x000D_
    color: white;_x000D_
    display: inline-block;_x000D_
    position: relative;_x000D_
    text-align: center;_x000D_
}_x000D_
.navitem.active_x000D_
{_x000D_
    background:green;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div class="navitem">Home</div>_x000D_
<div class="navitem">About</div>_x000D_
<div class="navitem">Pricing</div>

The above example can be simplified, but wanted to show the usage of this in the not() selector.

you can also use the line-height property on the ul

ul {
  line-height: 45px;
}

<ul>
<li>line one</li>
<li>line two</li>
<li>line three</li>
</ul>

When you're using get() you get a collection. In this case you need to iterate over it to get properties:

@foreach ($collection as $object)
    {{ $object->title }}
@endforeach

Or you could just get one of objects by it's index:

{{ $collection[0]->title }}

Or get first object from collection:

{{ $collection->first() }}

When you're using find() or first() you get an object, so you can get properties with simple:

{{ $object->title }}

The Better way to do that is:

For the details of specific Package

pip show <package_name>

It details out the Package_name, Version, Author, Location etc.

Ben is completely correct in his answer - so keep what he says in mind. What I'm about to tell you isn't a full explanation, but it's a very easy way to remember how e.target, e.currentTarget work in relation to mouse events and the display list:

e.target = The thing under the mouse (as ben says... the thing that triggers the event). e.currentTarget = The thing before the dot... (see below)

So if you have 10 buttons inside a clip with an instance name of "btns" and you do:

btns.addEventListener(MouseEvent.MOUSE_OVER, onOver);
// btns = the thing before the dot of an addEventListener call
function onOver(e:MouseEvent):void{
  trace(e.target.name, e.currentTarget.name);
}

e.target will be one of the 10 buttons and e.currentTarget will always be the "btns" clip.

It's worth noting that if you changed the MouseEvent to a ROLL_OVER or set the property btns.mouseChildren to false, e.target and e.currentTarget will both always be "btns".

You could avoid hardcoding the full path by setting a JS variable in the header of your template, before wp_head() is called, holding the template URL. Like:

<script type="text/javascript">
var templateUrl = '<?= get_bloginfo("template_url"); ?>';
</script>

And use that variable to set the background (I realize you know how to do this, I only include these details in case they helps others):

Reset.style.background = " url('"+templateUrl+"/images/searchfield_clear.png') ";

You can access the groups simply through the groups attribute on User.

from django.contrib.auth.models import User, Group

group = Group(name = "Editor")
group.save()                    # save this new group for this example
user = User.objects.get(pk = 1) # assuming, there is one initial user 
user.groups.add(group)          # user is now in the "Editor" group

then user.groups.all() returns [<Group: Editor>].

Alternatively, and more directly, you can check if a a user is in a group by:

if django_user.groups.filter(name = groupname).exists():

    ...

Note that groupname can also be the actual Django Group object.

In Eclipse this worked for me: right click project. -> Properties -> Library Section; Add (any library at all) -> select library and click remove -> press okay.

. is a shorthand for the current directory and is used in Linux and Unix to execute a compiled program in the current directory. That is why you don't see this used in Web Development much except by open source, non-Windows frameworks like Google Angular which was written by people stuck on open source platforms.

./ also resolves to the current directory and is atypical in Web but supported as a path in some open source frameworks. Because it resolves the same as no path to the current file directory its not used. Example: ./image.jpg = image.jpg. Again, this is a relic of Unix operating systems that need path resolutions like this to run executables and resolve paths for security reasons. Its not a typical web path. That is why this syntax is redundant.

../ is a traditional web path that goes one directory up

/ is the ROOT of your website

These path resolutions below are true...

./folder= folder this is always true in web path resolution

./file.html = file.html this is always true in web path resolution

./ = {no path} an empty path is the same as ./ in the web world

{no path} = / an empty path is the same as the web root if your file is in the root directory

./ = / ONLY if you are in the root folder

../ = / ONLY if you are one folder below the web root

This is not so much an answer to your original question as to one of the queries you had in the body of your question.

A little preamble, so that my naming doesn't seem strange:

import matplotlib
from matplotlib import rc
from matplotlib.figure import Figure
ax = self.figure.add_subplot( 111 )

As has been mentioned you can use ticklabel_format to specify that matplotlib should use scientific notation for large or small values:

ax.ticklabel_format(style='sci',scilimits=(-3,4),axis='both')

You can affect the way that this is displayed using the flags in rcParams (from matplotlib import rcParams) or by setting them directly. I haven't found a more elegant way of changing between '1e' and 'x10^' scientific notation than:

ax.xaxis.major.formatter._useMathText = True

This should give you the more Matlab-esc, and indeed arguably better appearance. I think the following should do the same:

rc('text', usetex=True)

I get exactly the reported error if ccache is enabled, when using CMake's Xcode generator. Disabling ccache fixed the problem for me. Below I present a fix/check that works for MacOS, but should work similarly on other platforms.

Apparently, it is possible to use CMake's Xcode generator (and others) also in combination with ccache, as is described here. But I never tried it out myself.

# 1) To check if ccache is enabled:
echo $CC
echo $CXX
# This prints something like the following: 
#     ccache clang -Qunused-arguments -fcolor-diagnostics. 
# CC or CXX are typically set in the `.bashrc` or `.zshrc` file.

# 2) To disable ccache, use the following:
CC=clang
CXX=clang++

# 3) Then regenerate the cmake project
cmake -G Xcode <path/to/CMakeLists.txt>

$(document).ready(function(){
 $('#category').change(function(){

    $('#app').change(function(){

        cache: false,
        success: function(ms)
            {
            $('#store').fadeIn().html(ms);

            }
            });// second ajAx
        });// second on change


     }// first  ajAx sucess
  });// firs ajAx
 });// firs on change

});

Use

finishAffinity ();

Instead of:

System.exit(); or finish();

it exit full application or all activity.

I am having the same problem while running the command-

python manage.py startapp < app_name >

but problem with me is that i was running that command out of virtual environment.So just activate your virtual environment first and run the command again -
