if not installed ARM EABI v7a System Image, you should install all.

FILE=test

while read CMD; do
    echo "$CMD"
done < "$FILE"

A redirection with < "$FILE" has a few advantages over cat "$FILE" | while .... It avoids a useless use of cat, saving an unnecessary child process. It also avoids a common pitfall where the loop runs in a subshell. In bash, commands in a | pipeline run in subshells, which means variable assignments are lost after the loop ends. Redirection with < doesn't have that problem, so you could use $CMD after the loop or modify other variables inside the loop. It also, again, avoids unnecessary child processes.

There are some additional improvements that could be made:

• Add IFS= so that read won't trim leading and trailing whitespace from each line.
• Add -r to read to prevent from backslashes from being interpreted as escape sequences.
• Lower case CMD and FILE. The bash convention is only environmental and internal shell variables are uppercase.
• Use printf in place of echo which is safer if $cmd is a string like -n, which echo would interpret as a flag.

file=test

while IFS= read -r cmd; do
    printf '%s\n' "$cmd"
done < "$file"

Copy paste: •. I've done it with other weird characters, such as ? and ?.

Edit: here's an example. The two Buttons at the bottom have android:text="?" and "?".

Just off the top of my head...

select c.commonID, t1.commonID, t2.commonID
from Common c
     left outer join Table1 t1 on t1.commonID = c.commonID
     left outer join Table2 t2 on t2.commonID = c.commonID
where t1.commonID is null 
     and t2.commonID is null

I ran a few tests and here were my results w.r.t. @patmortech's answer and @rexem's comments.

If either Table1 or Table2 is not indexed on commonID, you get a table scan but @patmortech's query is still twice as fast (for a 100K row master table).

If neither are indexed on commonID, you get two table scans and the difference is negligible.

If both are indexed on commonID, the "not exists" query runs in 1/3 the time.

you can watch all files like this

tsc *.ts --watch

If you use .Net 4.5 you can also use standard .Net json serializer:

using System.Runtime.Serialization.Json;
...    
Stream jsonSource = ...; // serializer will read data stream
var s = new DataContractJsonSerializer(typeof(string[][]));
var j = (string[][])s.ReadObject(jsonSource);

In .Net 4.5 and older you can use JavaScriptSerializer class:

using System.Web.Script.Serialization;
...
JavaScriptSerializer serializer = new JavaScriptSerializer();
string[][] list = serializer.Deserialize<string[][]>(json);

Here's a succinct and generic solution to use a seaborn color palette.

First find a color palette you like and optionally visualize it:

sns.palplot(sns.color_palette("Set2", 8))

Then you can use it with matplotlib doing this:

# Unique category labels: 'D', 'F', 'G', ...
color_labels = df['color'].unique()

# List of RGB triplets
rgb_values = sns.color_palette("Set2", 8)

# Map label to RGB
color_map = dict(zip(color_labels, rgb_values))

# Finally use the mapped values
plt.scatter(df['carat'], df['price'], c=df['color'].map(color_map))

I have added few lines inside package.json:

"scripts": {
  ...
  "clean": "rmdir /s /q node_modules",
  "reinstall": "npm run clean && npm install",
  "rebuild": "npm run clean && npm install && rmdir /s /q dist && npm run build --prod",
  ...
}

If you want to clean only you can use this rimraf node_modules.

From Python version 2.6 on you can use multiple arguments to set.intersection(), like

u = set.intersection(s1, s2, s3)

If the sets are in a list, this translates to:

u = set.intersection(*setlist)

where *a_list is list expansion

Note that set.intersection is not a static method, but this uses the functional notation to apply intersection of the first set with the rest of the list. So if the argument list is empty this will fail.

Doing type('') is effectively equivalent to str and types.StringType

so type('') == str == types.StringType will evaluate to "True"

Note that Unicode strings which only contain ASCII will fail if checking types in this way, so you may want to do something like assert type(s) in (str, unicode) or assert isinstance(obj, basestring), the latter of which was suggested in the comments by 007Brendan and is probably preferred.

isinstance() is useful if you want to ask whether an object is an instance of a class, e.g:

class MyClass: pass

print isinstance(MyClass(), MyClass) # -> True
print isinstance(MyClass, MyClass()) # -> TypeError exception

But for basic types, e.g. str, unicode, int, float, long etc asking type(var) == TYPE will work OK.

I had same issue with my WPF RSS reader, I originally went with Awesomium (I think version 1.6) Awesomium is great. You get a lot of control for caching (images and HTML content), JavaScript execution, intercepting downloads and so forth. It's also super fast. The process isolation means when browser crashes it does not crash the app.

But it's also heavy, even release build adds about 10-15mb (can't remember exact number) and hence a slight start-up penalty. I then realized, only problem I had with IE browser control was that it would throw the JavaScript errors every now and again. But that was fixed with the following snippet.

I hardly used my app on XP or Vista but on Win 7 and above it never crashed (at least not because I used IE browser control)

IOleServiceProvider sp = browser.Document as IOleServiceProvider;
if (sp != null)
{
    IID_IWebBrowserApp = new Guid("0002DF05-0000-0000-C000-000000000046");
    Guid IID_IWebBrowser2 = new Guid("D30C1661-CDAF-11d0-8A3E-00C04FC9E26E");

    webBrowser;
    sp.QueryService(ref IID_IWebBrowserApp, ref IID_IWebBrowser2, out webBrowser);
    if (webBrowser != null)
    {
        webBrowser.GetType().InvokeMember("Silent", 
                BindingFlags.Instance | BindingFlags.Public | BindingFlags.PutDispProperty, null, webBrowser, new object[] { silent });
    }
}

You would have to find the position of the element in the DIV you want to scroll to, and set the scrollTop property.

divElem.scrollTop = 0;

Update:

Sample code to move up or down

  function move_up() {
    document.getElementById('divElem').scrollTop += 10;
  }

  function move_down() {
    document.getElementById('divElem').scrollTop -= 10;
  }

** This will not work if multiple devices are plugged in

1. Creation and initialization

   Object[] yourArray = new Object[ARRAY_LENGTH];
   

2. Write access

   yourArray[i]= someArrayList;
   

   to access elements of internal ArrayList:

   ((ArrayList<YourType>) yourArray[i]).add(elementOfYourType); //or other method
   

3. Read access

   to read array element i as an ArrayList use type casting:

   someElement= (ArrayList<YourType>) yourArray[i];
   

   for array element i: to read ArrayList element at index j

   arrayListElement= ((ArrayList<YourType>) yourArray[i]).get(j);
   

You can do something similar to this:

// Get the parent to attatch the element into
var parent = document.getElementsByTagName("ul")[0];

// Create element with random id
var element = document.createElement("li");
element.id = "li-"+Math.floor(Math.random()*9999);

// Add event listener
element.addEventListener("click", EVENT_FN);

// Add to parent
parent.appendChild(element);

In Jackson 2.x, use:

@JsonInclude(JsonInclude.Include.NON_NULL)

You should set the src attribute after the onload event, f.ex:

el.onload = function() { //...
el.src = script;

You should also append the script to the DOM before attaching the onload event:

$body.append(el);
el.onload = function() { //...
el.src = script;

Remember that you need to check readystate for IE support. If you are using jQuery, you can also try the getScript() method: http://api.jquery.com/jQuery.getScript/

In SQL Server 2008-R2, I go to the design mode - in a test database - and add my two columns using the designer and made the settings with the GUI, and then the infamous Right-Click gives the option "Generate Change Script"!

Bang up pops a little window with, you guessed it, the properly formatted guaranteed-to-work change script. Hit the easy button.

Content (for text and not html):

http://www.quirksmode.org/css/content.html

But just to be clear, it is bad practice. Its support throughout browsers is shaky, and it's generally not a good idea. But in cases where you really have to use it, there it is.

document.querySelectorAll('data-foo')

to get list of all elements having attribute data-foo

If you want to get element with data attribute which is having some specific value e.g

<div data-foo="1"></div>
<div data-foo="2" ></div>

and I want to get div with data-foo set to "2"

document.querySelector('[data-foo="2"]')

But here comes the twist what if I want to match the data attirubte value with some variable's value like I want to get element if data-foo attribute is set to i

var i=2;

so you can dynamically select the element having specific data element using template literals

document.querySelector(`[data-foo="${i}"]`)

Note even if you don't write value in string it gets converted to string like if I write

<div data-foo=1></div>

and then inspect the element in Chrome developer tool the element will be shown as below

<div data-foo="1"></div>

You can also cross verify by writing below code in console

console.log(typeof document.querySelector(`[data-foo]="${i}"`).dataset('dataFoo'))

why I have written 'dataFoo' though the attribute is data-foo reason dataset properties are converted to camelCase properties

This is my first answer on stackoverflow please let me know how can I improve my answer writing way.

None. You need to set up the directory you've placed the website as a web application within IIS.

Java generics uses type erasure. The bit in the angle brackets (<Integer> and <String>) gets removed, so you'd end up with two methods that have an identical signature (the add(Set) you see in the error). That's not allowed because the runtime wouldn't know which to use for each case.

If Java ever gets reified generics, then you could do this, but that's probably unlikely now.

<ProgressBar
android:id="@+id/loading_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminateTintMode="src_atop"
android:indeterminateTint="@color/your_customized_color"
android:layout_gravity="center" />

The effect looks like this:

A good question. Should tell you it took some time to crack this one. Here is my result.

DECLARE @TABLE TABLE
(  
ID INT,  
USERS VARCHAR(10),  
ACTIVITY VARCHAR(10),  
PAGEURL VARCHAR(10)  
)

INSERT INTO @TABLE

        (2, 'Me', 'act1', 'cd'),
        (3, 'You', 'act2', 'xy'),
        (4, 'You', 'act2', 'st')


SELECT T1.USERS, T1.ACTIVITY,   
        STUFF(  
        (  
        SELECT ',' + T2.PAGEURL  
        FROM @TABLE T2  
        WHERE T1.USERS = T2.USERS  
        FOR XML PATH ('')  
        ),1,1,'')  
FROM @TABLE T1  
GROUP BY T1.USERS, T1.ACTIVITY

If someone have this problem, maybe you just have to install build-essential.

apt install build-essential

Easy:

print my_queryset.query

For example:

from django.contrib.auth.models import User
print User.objects.filter(last_name__icontains = 'ax').query

It should also be mentioned that if you have DEBUG = True, then all of your queries are logged, and you can get them by accessing connection.queries:

from django.db import connections
connections['default'].queries

The django debug toolbar project uses this to present the queries on a page in a neat manner.

Put this in your init function:

$.ajaxSetup({
  xhrFields: {
    withCredentials: true
  }
});

It will work.

Update null elements with value in the same location in other. Combines a DataFrame with other DataFrame using func to element-wise combine columns. The row and column indexes of the resulting DataFrame will be the union of the two.

df1 = pd.DataFrame({'A': [None, 0], 'B': [None, 4]})
df2 = pd.DataFrame({'A': [1, 1], 'B': [3, 3]})
df1.combine_first(df2)
     A    B
0  1.0  3.0
1  0.0  4.0

I removed C:\ProgramData\Oracle\Java\javapath from my path, and it worked for me.

But make sure you include x64 JDK and JRE addresses in your path.

You are giving multiple Content-Type headers. application/vnd.ms-excel is enough.

And there are couple of syntax error too. To statement termination with ; on the echo statement and wrong filename extension.

header("Content-Disposition: attachment; filename=abc.xls");  //File name extension was wrong
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);

Found this question while googling "node https" but the example in the accepted answer is very old - taken from the docs of the current (v0.10) version of node, it should look like this:

var https = require('https');
var fs = require('fs');

var options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};

https.createServer(options, function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}).listen(8000);

Maybe ICMP packets are blocked by your (mobile) provider. If this code doesn't work on the emulator try to sniff via wireshark or any other sniffer and have a look whats up on the wire when you fire the isReachable() method.

SQL*Plus uses &1, &2... &n to access the parameters.

Suppose you have the following script test.sql:

SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off

you could call this script like this for example:

$ sqlplus login/pw @test Hello World!

Edit:

In a UNIX script you would usually call a SQL script like this:

sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF

so that your login/password won't be visible with another session's ps

Strangely, the answers above removes the 'duplicates' but what if I want to remove the duplicated value also?? The following should be useful and does not create a new object in memory!

def dictRemoveDuplicates(self):
    a=[[1,'somevalue1'],[1,'somevalue2'],[2,'somevalue1'],[3,'somevalue4'],[5,'somevalue5'],[5,'somevalue1'],[5,'somevalue1'],[5,'somevalue8'],[6,'somevalue9'],[6,'somevalue0'],[6,'somevalue1'],[7,'somevalue7']]


print(a)
temp = 0
position = -1
for pageNo, item in a:
    position+=1
    if pageNo != temp:
        temp = pageNo
        continue
    else:
        a[position] = 0
        a[position - 1] = 0
a = [x for x in a if x != 0]         
print(a)

and the o/p is:

[[1, 'somevalue1'], [1, 'somevalue2'], [2, 'somevalue1'], [3, 'somevalue4'], [5, 'somevalue5'], [5, 'somevalue1'], [5, 'somevalue1'], [5, 'somevalue8'], [6, 'somevalue9'], [6, 'somevalue0'], [6, 'somevalue1'], [7, 'somevalue7']]
[[2, 'somevalue1'], [3, 'somevalue4'], [7, 'somevalue7']]

I was getting the 400 Bad Request error, even after setting:

contentType: "application/json",
dataType: "json"

The issue was with the type of a property passed in the json object, for the data property in the ajax request object.
To figure out the issue, I added an error handler and then logged the error to the console. Console log will clearly show validation errors for the properties if any.

This was my initial code:

var data = {
    "TestId": testId,
    "PlayerId": parseInt(playerId),
    "Result": result
};

var url = document.location.protocol + "//" + document.location.host + "/api/tests"
$.ajax({
    url: url,
    method: "POST",
    contentType: "application/json",
    data: JSON.stringify(data), // issue with a property type in the data object
    dataType: "json",
    error: function (e) {
        console.log(e); // logging the error object to console
    },
    success: function () {
        console.log('Success saving test result');
    }
});

Now after making the request, I checked the console tab in the browser development tool.
It looked like this:

responseJSON.errors[0] clearly shows a validation error: The JSON value could not be converted to System.String. Path: $.TestId, which means I have to convert TestId to a string in the data object, before making the request.

Changing the data object creation like below fixed the issue for me:

var data = {
        "TestId": String(testId), //converting testId to a string
        "PlayerId": parseInt(playerId),
        "Result": result
};

I assume other possible errors could also be identified by logging and inspecting the error object.

From this blog post:

XE: Changing the default http port

Oracle XE uses the embedded http listener that comes with the XML DB (XDB) to serve http requests. The default port for HTTP access is 8080.

EDIT:

Update 8080 port to which port(9090 for example) you like

SQL> -- set http port
SQL> begin
 2    dbms_xdb.sethttpport('9090');
 3  end;
 4  /

After changing the port, when we start Oracle it will go on port 8080, we should type manually new port(9090) in the address bar to run Oracle XE.

According to MDN, the way to retrieve an item from a NodeList is:

nodeItem = nodeList.item(index)

Thus:

var slides = document.getElementsByClassName("slide");
for (var i = 0; i < slides.length; i++) {
   Distribute(slides.item(i));
}

I haven't tried this myself (the normal for loop has always worked for me), but give it a shot.

The best way use Java 8 time API:

  LocalDateTime ldt = timeStamp.toLocalDateTime();
  Timestamp ts = Timestamp.valueOf(ldt);

For use with JPA put in with your model (https://weblogs.java.net/blog/montanajava/archive/2014/06/17/using-java-8-datetime-classes-jpa):

@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {
    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime ldt) {
        return Timestamp.valueOf(ldt);
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp ts) {
        return ts.toLocalDateTime();
    }
}

So now it is relative timezone independent time. Additionally it is easy do:

  LocalDate ld = ldt.toLocalDate();
  LocalTime lt = ldt.toLocalTime();

Formatting:

 DateTimeFormatter DATE_TME_FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm")
 String str = ldt.format(DATE_TME_FORMATTER);
 ldt = LocalDateTime.parse(str, DATE_TME_FORMATTER);

UPDATE: postgres 9.4.1208, HSQLDB 2.4.0 etc understand Java 8 Time API without any conversations!

});

Hope this helps. :)

I have the same problem. Mine is caused by a vmware installation. It is vmware worstation v8 on windows 7 and was a default installation.

Running netstat -aon | find ":80" | find "LISTENING" from cmd showed PID of the service causing the problem, this related to vmware. Going to services, I manually stopped all of the running vmware services (did not change their start up type, just a manual stop - I want them to work again after the next reboot) I could immediately test my webservice, glassfish 4 started as it should.

Hope it helps

For numerous reasons, No.

Why is explained in this MSDN post.

First, from a performance perspective the pointers get larger, so data structures get larger, and the processor cache stays the same size. That basically results in a raw speed hit (your mileage may vary). So you start in a hole and you have to dig yourself out of that hole by using the extra memory above 4G to your advantage. In Visual Studio this can happen in some large solutions but I think a preferable thing to do is to just use less memory in the first place. Many of VS’s algorithms are amenable to this. Here’s an old article that discusses the performance issues at some length: https://docs.microsoft.com/archive/blogs/joshwil/should-i-choose-to-take-advantage-of-64-bit

Secondly, from a cost perspective, probably the shortest path to porting Visual Studio to 64 bit is to port most of it to managed code incrementally and then port the rest. The cost of a full port of that much native code is going to be quite high and of course all known extensions would break and we’d basically have to create a 64 bit ecosystem pretty much like you do for drivers. Ouch.

I got it working after re-doing everything and then creating an empty project with XCode and building/running it to the device. XCode showed a window asking something like: Do you want to accept the developer certificate. I pressed "Always". Only after this step I got rid of the message "A valid signing identity matching this profile could not be found in your keychain" in Organizer.

Try to replace 'w' for 'iw'. For example:

Nobody has explained the difference between ExceptionDispatchInfo.Capture( ex ).Throw() and a plain throw, so here it is. However, some people have noticed the problem with throw.

The complete way to rethrow a caught exception is to use ExceptionDispatchInfo.Capture( ex ).Throw() (only available from .Net 4.5).

Below there are the cases necessary to test this:

1.

void CallingMethod()
{
    //try
    {
        throw new Exception( "TEST" );
    }
    //catch
    {
    //    throw;
    }
}

2.

void CallingMethod()
{
    try
    {
        throw new Exception( "TEST" );
    }
    catch( Exception ex )
    {
        ExceptionDispatchInfo.Capture( ex ).Throw();
        throw; // So the compiler doesn't complain about methods which don't either return or throw.
    }
}

3.

void CallingMethod()
{
    try
    {
        throw new Exception( "TEST" );
    }
    catch
    {
        throw;
    }
}

4.

void CallingMethod()
{
    try
    {
        throw new Exception( "TEST" );
    }
    catch( Exception ex )
    {
        throw new Exception( "RETHROW", ex );
    }
}

Case 1 and case 2 will give you a stack trace where the source code line number for the CallingMethod method is the line number of the throw new Exception( "TEST" ) line.

However, case 3 will give you a stack trace where the source code line number for the CallingMethod method is the line number of the throw call. This means that if the throw new Exception( "TEST" ) line is surrounded by other operations, you have no idea at which line number the exception was actually thrown.

Case 4 is similar with case 2 because the line number of the original exception is preserved, but is not a real rethrow because it changes the type of the original exception.

To make angular ui $modal work with bootstrap 3 you need to overwrite the styles

.modal {
    display: block;
}
.modal-body:before,
.modal-body:after {
    display: table;
    content: " ";
}
.modal-header:before,
.modal-header:after {
    display: table;
    content: " ";
}

(The last ones are necessary if you use custom directives) and encapsulate the html with

<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>

I think that your problem is actually with not correctly indenting init function.It should be like this

class MyClass():
     def __init__(self, filename):
          pass

     def parse_file():
          pass

I'm using the following CSS only trick:

  input[type="date"]:before {_x000D_
    content: attr(placeholder) !important;_x000D_
    color: #aaa;_x000D_
    margin-right: 0.5em;_x000D_
  }_x000D_
  input[type="date"]:focus:before,_x000D_
  input[type="date"]:valid:before {_x000D_
    content: "";_x000D_
  }

<input type="date" placeholder="Choose a Date" />

For linux you can install it via

sudo apt-get install php5-curl

For Windows(removing the ;) from php.ini

;extension=php_curl.dll

Restart apache server.

you can use this command

pg_dump --table=yourTable --data-only --column-inserts yourDataBase > file.sql

you should change yourTable, yourDataBase to your case

Same here. I had this error when running an import command from terminal without activating python3 shell through manage.py in a django project (yes, I am a newbie yet). As one must expect, activating shell allowed the command to be interpreted correctly.

./manage.py shell

and only then

>>> from django.contrib.sites.models import Site

Seems like last_accessed_on, is a date time, and you are converting '23-07-2014 09:37:00' to a varchar. This would not work, and give you conversion errors. Try

last_accessed_on= convert(datetime,'23-07-2014 09:37:00', 103)  

I think you can avoid the cast though, and update with '23-07-2014 09:37:00'. It should work given that the format is correct.

Your query is not going to work because in last_accessed_on (which is DateTime2 type), you are trying to pass a Varchar value.

You query would be

UPDATE  student_queues SET  Deleted=0 ,  last_accessed_by='raja', last_accessed_on=convert(datetime,'23-07-2014 09:37:00', 103)  
 WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

The delete / drop option in operations is not present in my version.

Go to CPanel -> MySQLDatabase (icon next to PhPMyAdmin) -> check the DB to be delete -> delete.

I think, the convention that is generally followed is this:

• static class within a top level class is a nested class
• non static class within a top level class is a inner class, which further has two more form:
  • local class - named classes declared inside of a block like a method or constructor body
  • anonymous class - unnamed classes whose instances are created in expressions and statements

However, few other points to remembers are:

• Top level classes and static nested class are semantically same except that in case of static nested class it can make static reference to private static fields/methods of its Outer [parent] class and vice versa.

• Inner classes have access to instance variables of the enclosing instance of the Outer [parent] class. However, not all inner classes have enclosing instances, for example inner classes in static contexts, like an anonymous class used in a static initializer block, do not.

• Anonymous class by default extends the parent class or implements the parent interface and there is no further clause to extend any other class or implement any more interfaces. So,

  • new YourClass(){}; means class [Anonymous] extends YourClass {}
  • new YourInterface(){}; means class [Anonymous] implements YourInterface {}

I feel that the bigger question that remains open which one to use and when? Well that mostly depends on what scenario you are dealing with but reading the reply given by @jrudolph may help you making some decision.

Enumerations in C are basically syntactical sugar for named lists of automatically-sequenced integer values. That is, when you have this code:

int main()
{
    enum Days{Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday};

    Days TheDay = Monday;
}

Your compiler actually spits out this:

int main()
{
    int TheDay = 1; // Monday is the second enumeration, hence 1. Sunday would be 0.
}

Therefore, outputting a C enumeration as a string is not an operation that makes sense to the compiler. If you want to have human-readable strings for these, you will need to define functions to convert from enumerations to strings.

Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec

Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec, as I have ~/bin in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...

Launch it from the root of your project, where you can see src and target dirs.

The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)

$ mvnexec 
 1) org.jmeld.ui.JMeldComponent
 2) org.jmeld.ui.text.FileDocument
 3) org.jmeld.JMeld
 4) org.jmeld.util.UIDefaultsPrint
 5) org.jmeld.util.PrintProperties
 6) org.jmeld.util.file.DirectoryDiff
 7) org.jmeld.util.file.VersionControlDiff
 8) org.jmeld.vc.svn.InfoCmd
 9) org.jmeld.vc.svn.DiffCmd
10) org.jmeld.vc.svn.BlameCmd
11) org.jmeld.vc.svn.LogCmd
12) org.jmeld.vc.svn.CatCmd
13) org.jmeld.vc.svn.StatusCmd
14) org.jmeld.vc.git.StatusCmd
15) org.jmeld.vc.hg.StatusCmd
16) org.jmeld.vc.bzr.StatusCmd
17) org.jmeld.Main
18) org.apache.commons.jrcs.tools.JDiff
#? 

If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P)

By default it compiles project every run. but you can avoid that using mvnexec -B

It allows to search only in test classes -M or --no-main, or only in main classes -T or --no-test. also has a filter by name option -f <whatever>

Hope this could save you some time, for me it does.

For windows users:

I found this solution after days. Firstly which python version you want to install?

If you want for Python 2.7 version:

STEP 1:

scipy-0.19.0-cp27-cp27m-win32.whl

scipy-0.19.0-cp27-cp27m-win_amd64.whl

numpy-1.11.3+mkl-cp27-cp27m-win32.whl

numpy-1.11.3+mkl-cp27-cp27m-win_amd64.whl

If you want for Python 3.4 version:

scipy-0.19.0-cp34-cp34m-win32.whl

scipy-0.19.0-cp34-cp34m-win_amd64.whl

numpy-1.11.3+mkl-cp34-cp34m-win32.whl

numpy-1.11.3+mkl-cp34-cp34m-win_amd64.whl

If you want for Python 3.5 version:

scipy-0.19.0-cp35-cp35m-win32.whl

scipy-0.19.0-cp35-cp35m-win_amd64.whl

numpy-1.11.3+mkl-cp35-cp35m-win32.whl

numpy-1.11.3+mkl-cp35-cp35m-win_amd64.whl

If you want for Python 3.6 version:

scipy-0.19.0-cp36-cp36m-win32.whl

scipy-0.19.0-cp36-cp36m-win_amd64.whl

numpy-1.11.3+mkl-cp36-cp36m-win32.whl

numpy-1.11.3+mkl-cp36-cp36m-win_amd64.whl

Link: [click[1]

Once finish installation, go to your directory.

For example my directory:

cd C:\Users\asus\AppData\Local\Programs\Python\Python35\Scripts>
pip install [where/is/your/downloaded/scipy_whl.]

STEP 2:

Numpy+MKL

From same web site based on python version again:

After that use same thing again in Script folder

cd C:\Users\asus\AppData\Local\Programs\Python\Python35\Scripts>
pip3 install [where/is/your/downloaded/numpy_whl.]

And test it in python folder.

Python35>python 
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

Amit, I have used one way to achieve this with less coding and more efficient way.

but it uses Linq.

I posted it here because maybe the answer helps other SO.

Below DAL code converts datatable object to List of YourViewModel and it's easy to understand.

public static class DAL
{
        public static string connectionString = ConfigurationManager.ConnectionStrings["YourWebConfigConnection"].ConnectionString;

        // function that creates a list of an object from the given data table
        public static List<T> CreateListFromTable<T>(DataTable tbl) where T : new()
        {
            // define return list
            List<T> lst = new List<T>();

            // go through each row
            foreach (DataRow r in tbl.Rows)
            {
                // add to the list
                lst.Add(CreateItemFromRow<T>(r));
            }

            // return the list
            return lst;
        }

        // function that creates an object from the given data row
        public static T CreateItemFromRow<T>(DataRow row) where T : new()
        {
            // create a new object
            T item = new T();

            // set the item
            SetItemFromRow(item, row);

            // return 
            return item;
        }

        public static void SetItemFromRow<T>(T item, DataRow row) where T : new()
        {
            // go through each column
            foreach (DataColumn c in row.Table.Columns)
            {
                // find the property for the column
                PropertyInfo p = item.GetType().GetProperty(c.ColumnName);

                // if exists, set the value
                if (p != null && row[c] != DBNull.Value)
                {
                    p.SetValue(item, row[c], null);
                }
            }
        }

        //call stored procedure to get data.
        public static DataSet GetRecordWithExtendedTimeOut(string SPName, params SqlParameter[] SqlPrms)
        {
            DataSet ds = new DataSet();
            SqlCommand cmd = new SqlCommand();
            SqlDataAdapter da = new SqlDataAdapter();
            SqlConnection con = new SqlConnection(connectionString);

            try
            {
                cmd = new SqlCommand(SPName, con);
                cmd.Parameters.AddRange(SqlPrms);
                cmd.CommandTimeout = 240;
                cmd.CommandType = CommandType.StoredProcedure;
                da.SelectCommand = cmd;
                da.Fill(ds);
            }
            catch (Exception ex)
            {
               return ex;
            }

            return ds;
        }
}

Now, The way to pass and call method is below.

    DataSet ds = DAL.GetRecordWithExtendedTimeOut("ProcedureName");

    List<YourViewModel> model = new List<YourViewModel>();

    if (ds != null)
    {
        //Pass datatable from dataset to our DAL Method.
        model = DAL.CreateListFromTable<YourViewModel>(ds.Tables[0]);                
    }      

Till the date, for many of my applications, I found this as the best structure to get data.

$("#btnOpenEditing").off('click');
$("#btnOpenEditing").on('click', function (e) {

    });
});

It will work like charm take a look at the demo.

Don't know if it helps, but the "foreach" goes through all the keys: for (var key in obj1) {...}

The warning comes from the fact that you're dereferencing src in the assignment. The expression *src has type char, which is an integral type. The expression "anotherstring" has type char [14], which in this particular context is implicitly converted to type char *, and its value is the address of the first character in the array. So, you wind up trying to assign a pointer value to an integral type, hence the warning. Drop the * from *src, and it should work as expected:

src = "anotherstring";

since the type of src is char *.

You could also, higlight the text you want to change, then navigate to - 'Edit' > 'Convert Case to' choose UPPERCASE or lowercase (as required).

Changing Command Execute Timeout in Management Studio:

Click on Tools -> Options

Select Query Execution from tree on left side and enter command timeout in "Execute Timeout" control.

Changing Command Timeout in Server:

In the object browser tree right click on the server which give you timeout and select "Properties" from context menu.

Now in "Server Properties -....." dialog click on "Connections" page in "Select a Page" list (on left side). On the right side you will get property

Remote query timeout (in seconds, 0 = no timeout):
[up/down control]

you can set the value in up/down control.

As EvanK stated each do script line will open a new window however you can run
two commands with the same do script by separating them with a semicolon. For example:

tell application "Terminal"
    do script "date;time"
end tell

But the limit appears to be two commands.

However, you can append "in window 1" to the do script command (for every do script after the first one) to get the same effect and continue to run as many commands as you need to in the same window:

tell application "Terminal"
    do script "date"
    do script "time" in window 1
    do script "who" in window 1
end tell

Note that I just used the who, date, and time command as an example...replace with whatever commands you need.

>>> import re
>>> st = " i think mabe 124 + <font color=\"black\"><font face=\"Times New Roman\">but I don't have a big experience it just how I see it in my eyes <font color=\"green\"><font face=\"Arial\">fun stuff"
>>> re.sub("<.*?>","",st)
" i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"

If you use React this should work:

<a href="#" onClick={()=>window.open("https://...")}</a>

A very very good document regarding this topic is Troubleshooting Guide for Java from (originally) Sun. See the chapter "Troubleshooting System Crashes" for information about hs_err_pid* Files.

See Appendix C - Fatal Error Log

Per the guide, by default the file will be created in the working directory of the process if possible, or in the system temporary directory otherwise. A specific location can be chosen by passing in the -XX:ErrorFile product flag. It says:

If the -XX:ErrorFile= file flag is not specified, the system attempts to create the file in the working directory of the process. In the event that the file cannot be created in the working directory (insufficient space, permission problem, or other issue), the file is created in the temporary directory for the operating system.

Related answer, but if you want to run clean up a user inputting values into a form, here's what you can do:

const numFormatter = new Intl.NumberFormat('en-US', {
  style: "decimal",
  maximumFractionDigits: 2
})

// Good Inputs
parseFloat(numFormatter.format('1234').replace(/,/g,"")) // 1234
parseFloat(numFormatter.format('123').replace(/,/g,"")) // 123

// 3rd decimal place rounds to nearest
parseFloat(numFormatter.format('1234.233').replace(/,/g,"")); // 1234.23
parseFloat(numFormatter.format('1234.239').replace(/,/g,"")); // 1234.24

// Bad Inputs
parseFloat(numFormatter.format('1234.233a').replace(/,/g,"")); // NaN
parseFloat(numFormatter.format('$1234.23').replace(/,/g,"")); // NaN

// Edge Cases
parseFloat(numFormatter.format(true).replace(/,/g,"")) // 1
parseFloat(numFormatter.format(false).replace(/,/g,"")) // 0
parseFloat(numFormatter.format(NaN).replace(/,/g,"")) // NaN

Use the international date local via format. This cleans up any bad inputs, if there is one it returns a string of NaN you can check for. There's no way currently of removing commas as part of the locale (as of 10/12/19), so you can use a regex command to remove commas using replace.

ParseFloat converts the this type definition from string to number

If you use React, this is what your calculate function could look like:

updateCalculationInput = (e) => {
    let value;
    value = numFormatter.format(e.target.value); // 123,456.78 - 3rd decimal rounds to nearest number as expected
    if(value === 'NaN') return; // locale returns string of NaN if fail
    value = value.replace(/,/g, ""); // remove commas
    value = parseFloat(value); // now parse to float should always be clean input

    // Do the actual math and setState calls here
}

You can set UINavigation Background color by using this code in any view controller

self.navigationController.navigationBar.backgroundColor = [UIColor colorWithRed:10.0f/255.0f green:30.0f/255.0f blue:200.0f/255.0f alpha:1.0f];

If you're using JDBC, then you have the option

The Date() object in javascript is not that smart really.

If you just focus on adding seconds it seems to handle things smoothly but if you try to add X number of seconds then add X number of minute and hours, etc, to the same Date object you end up in trouble. So I simply fell back to only using the setSeconds() method and converting my data into seconds (which worked fine).

If anyone can demonstrate adding time to a global Date() object using all the set methods and have the final time come out correctly I would like to see it but I get the sense that one set method is to be used at a time on a given Date() object and mixing them leads to a mess.

var vTime = new Date();

var iSecondsToAdd = ( iSeconds + (iMinutes * 60) + (iHours * 3600) + (iDays * 86400) );

vTime.setSeconds(iSecondsToAdd);

Here is some more documentation that may help:

#include <iostream>
#include <sstream>

std::ostringstream o;
o << name << age;
std::cout << o.str();

Use this

public static boolean isNum(String strNum) {
    boolean ret = true;
    try {

        Double.parseDouble(strNum);

    }catch (NumberFormatException e) {
        ret = false;
    }
    return ret;
}

add this to you CSS:

html, body
{
    height: 100%;
}

working Fiddle

when you say to wrap to be 100%, 100% of what? of its parent (body), so his parent has to have some height.

and the same goes for body, his parent his html. html parent his the viewport.. so, by setting them both to 100%, wrap can also have a percentage height.

also: the elements have some default padding/margin, that causes them to span a little more then the height you applied to them. (causing a scroll bar) you can use

*
{
    padding: 0;
    margin: 0;
}

to disable that.

Look at That Fiddle

Historically, it's been impossible to make these things disappear as they are user settings and not considered part of the page you have control over.

However, as of 2017, the @page at-rule has been standardized, which can be used to hide the page title and date in modern browsers:

@page { size: auto;  margin: 0mm; }

Print headers/footers and print margins

When printing Web documents, margins are set in the browser's Page Setup (or Print Setup) dialog box. These margin settings, although set within the browser, are controlled at the operating system/printer driver level and are not controllable at the HTML/CSS/DOM level. (For CSS-controlled printed page headers and footers see Printing Headers .)

The settings must be big enough to encompass the printer's physical non-printing areas. Further, they must be big enough to encompass the header and footer that the browser is usually configured to print (typically the page title, page number, URL and date). Note that these headers and footers, although specified by the browser and usually configurable through user preferences, are not part of the Web page itself and therefore are not controllable by CSS. In CSS terms, they fall outside the Page Box CSS2.1 Section 13.2.

... i.e. setting a margin of 0 hides the page title because the title is printed in the margin.

When you boil down to it, it's just a fancy overly-complicated proxy, but maybe Catch-All Proxies could do it?

var o = {
    a: 'a',
    b: 'b',
    func: function() { return 'func'; }
};

var proxy = Proxy.create(handlerMaker(o), o);

(function(x){
    var obj = x;
    console.log(x.a);
    console.log(x.b);
    obj.foo = 'foo';
    obj.bar = 'bar';
})(proxy);

console.log(o.foo);

function handlerMaker(obj) {
  return {
   getOwnPropertyDescriptor: function(name) {
     var desc = Object.getOwnPropertyDescriptor(obj, name);
     // a trapping proxy's properties must always be configurable
     if (desc !== undefined) { desc.configurable = true; }
     return desc;
   },
   getPropertyDescriptor:  function(name) {
     var desc = Object.getOwnPropertyDescriptor(obj, name); // not in ES5
     // a trapping proxy's properties must always be configurable
     if (desc !== undefined) { desc.configurable = true; }
     return desc;
   },
   getOwnPropertyNames: function() {
     return Object.getOwnPropertyNames(obj);
   },
   getPropertyNames: function() {
     return Object.getPropertyNames(obj);                // not in ES5
   },
   defineProperty: function(name, desc) {

   },
   delete:       function(name) { return delete obj[name]; },   
   fix:          function() {}
  };
}

You can use Configuration to resolve this.

Ex (Startup.cs):

You can pass by DI to the controllers after this implementation.

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

        Configuration = builder.Build();

    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {

        var microserviceName = Configuration["microserviceName"];

       services.AddSingleton(Configuration);

       ...
    }

In my case, correct .net version was not installed on my PC. I install the .net 3.5 on my pc and that worked for me.

A scriptable object is an object that records the operations done to it and it can store them as a "script" which can be replayed.

For example, see: Application Scripting Framework

Now, if Alistair didn't know what he asked and really meant "subscriptable" objects (as edited by others), then (as mipadi also answered) this is the correct one:

A subscriptable object is any object that implements the __getitem__ special method (think lists, dictionaries).

Using Jquery, simply use this function:

<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
}
</script>

Your print button will look like this:

<button id="print" onclick="printContent('id name of your div');" >Print</button>

Edit: If you DO have form data that you need to keep, clone won't copy that, so you'll just need to grab all the form data and replace it after restore as so:

<script>
function printContent(el){
var restorepage = $('body').html();
var printcontent = $('#' + el).clone();
var enteredtext = $('#text').val();
$('body').empty().html(printcontent);
window.print();
$('body').html(restorepage);
$('#text').html(enteredtext);
}
</script>
<textarea id="text"></textarea>

gahooa's answer is correct for the question as phrased in the heading, but if the lists are already numpy format or larger than ten it will be MUCH faster (3 orders of magnitude) as well as more readable, to do simple numpy multiplication as suggested by NPE. I get these timings:

0.0049ms -> N = 4, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0075ms -> N = 4, a = [i for i in range(N)], c = a * b
0.0167ms -> N = 4, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0013ms -> N = 4, a = np.arange(N), c = a * b
0.0171ms -> N = 40, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0095ms -> N = 40, a = [i for i in range(N)], c = a * b
0.1077ms -> N = 40, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0013ms -> N = 40, a = np.arange(N), c = a * b
0.1485ms -> N = 400, a = [i for i in range(N)], c = [a*b for a,b in zip(a, b)]
0.0397ms -> N = 400, a = [i for i in range(N)], c = a * b
1.0348ms -> N = 400, a = np.arange(N), c = [a*b for a,b in zip(a, b)]
0.0020ms -> N = 400, a = np.arange(N), c = a * b

i.e. from the following test program.

import timeit

init = ['''
import numpy as np
N = {}
a = {}
b = np.linspace(0.0, 0.5, len(a))
'''.format(i, j) for i in [4, 40, 400] 
                  for j in ['[i for i in range(N)]', 'np.arange(N)']]

func = ['''c = [a*b for a,b in zip(a, b)]''',
'''c = a * b''']

for i in init:
  for f in func:
    lines = i.split('\n')
    print('{:6.4f}ms -> {}, {}, {}'.format(
           timeit.timeit(f, setup=i, number=1000), lines[2], lines[3], f))

You can try joda-time.

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

1. You're deleting your table and replacing it with an int
2. You aren't pulling a value from the table

Try:

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

based on @CanalDoMestre's answer. I added support for the blank filter case, fixed a typo and prevented hiding the rows so I can still see the column headers.

    $("#filterby").on('keyup', function() {
        if (this.value.length < 1) {
            $("#list tr").css("display", "");
        } else {
            $("#list tbody tr:not(:contains('"+this.value+"'))").css("display", "none");
            $("#list tbody tr:contains('"+this.value+"')").css("display", "");
        }
    });

As we can see in ActionController::Base, before_action is just a new syntax for before_filter.

However all before_filters syntax are deprecated in Rails 5.0 and will be removed in Rails 5.1

IMHO no more info than @Florjon gave is needed. Maybe some small details are left to understand why it might not work for us sometimes.

First of all, the &#xa (hex) or &#10 (dec) inside a <xsl:text/> will always work, but you may not see it.

1. There is no newline in a HTML markup. Using a simple <br/> will do fine. Otherwise you'll see a white space. Viewing the source from the browser will tell you what really happened. However, there are cases you expect this behaviour, especially if the consumer is not directly a browser. For instance, you want to create an HTML page and view its structure formatted nicely with empty lines and idents before serving it to the browser.
2. Remember where you need to use disable-output-escaping and where you don't. Take the following example where I had to create an xml from another and declare its DTD from a stylesheet.

The first version does escape the characters (default for xsl:text)

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output method="xml" indent="yes" encoding="utf-8"/>

    <xsl:template match="/">
        <xsl:text>&lt;!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd"&gt;&#xa;&#xa;&#xd;</xsl:text>
        <xsl:copy>
            <xsl:apply-templates select="*" mode="copy"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="@*|node()" mode="copy">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" mode="copy"/>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

and here is the result:

<?xml version="1.0" encoding="utf-8"?>
&lt;!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd"&gt;

&#13;<Subscriptions>
    <User id="1"/>   
</Subscriptions>

Ok, it does what we expect, escaping is done so that the characters we used are displayed properly. The XML part formatting inside the root node is handled by ident="yes". But with a closer look we see that the newline character &#xa was not escaped and translated as is, performing a double linefeed! I don't have an explanation on this, will be good to know. Anyone?

The second version does not escape the characters so they're producing what they're meant for. The change made was:

<xsl:text disable-output-escaping="yes">&lt;!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd"&gt;&#xa;&#xa;&#xd;</xsl:text>

and here is the result:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Subscriptions SYSTEM "Subscriptions.dtd">

<Subscriptions>
    <User id="1"/>   
</Subscriptions>

and that will be ok. Both cr and lf are properly rendered.

3. Don't forget we're talking about nl, not crlf (nl=lf). My first attempt was to use only cr:&#xd and while the output xml was validated by DOM properly.

I was viewing a corrupted xml:

<?xml version="1.0" encoding="utf-8"?>
<Subscriptions>riptions SYSTEM "Subscriptions.dtd">
    <User id="1"/>   
</Subscriptions>

DOM parser disregarded control characters but the rendered didn't. I spent quite some time bumping my head before I realised how silly I was not seeing this!

For the record, I do use a variable inside the body with both CRLF just to be 100% sure it will work everywhere.

Try:

call msbuild.bat
call unit-tests.bat
call deploy.bat

I looked into this as well, and after comparing the SqlDataAdapter.Fill method with the SqlDataReader.Load funcitons, I've found that the SqlDataAdapter.Fill method is more than twice as fast with the result sets I've been using

Used code:

    [TestMethod]
    public void SQLCommandVsAddaptor()
    {
        long AdapterFillLargeTableTime, readerLoadLargeTableTime, AdapterFillMediumTableTime, readerLoadMediumTableTime, AdapterFillSmallTableTime, readerLoadSmallTableTime, AdapterFillTinyTableTime, readerLoadTinyTableTime;

        string LargeTableToFill = "select top 10000 * from FooBar";
        string MediumTableToFill = "select top 1000 * from FooBar";
        string SmallTableToFill = "select top 100 * from FooBar";
        string TinyTableToFill = "select top 10 * from FooBar";

        using (SqlConnection sconn = new SqlConnection("Data Source=.;initial catalog=Foo;persist security info=True; user id=bar;password=foobar;"))
        {
            // large data set measurements
            AdapterFillLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteDataAdapterFillStep);
            readerLoadLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteSqlReaderLoadStep);
            // medium data set measurements
            AdapterFillMediumTableTime = MeasureExecutionTimeMethod(sconn, MediumTableToFill, ExecuteDataAdapterFillStep);
            readerLoadMediumTableTime = MeasureExecutionTimeMethod(sconn, MediumTableToFill, ExecuteSqlReaderLoadStep);
            // small data set measurements
            AdapterFillSmallTableTime = MeasureExecutionTimeMethod(sconn, SmallTableToFill, ExecuteDataAdapterFillStep);
            readerLoadSmallTableTime = MeasureExecutionTimeMethod(sconn, SmallTableToFill, ExecuteSqlReaderLoadStep);
            // tiny data set measurements
            AdapterFillTinyTableTime = MeasureExecutionTimeMethod(sconn, TinyTableToFill, ExecuteDataAdapterFillStep);
            readerLoadTinyTableTime = MeasureExecutionTimeMethod(sconn, TinyTableToFill, ExecuteSqlReaderLoadStep);
        }
        using (StreamWriter writer = new StreamWriter("result_sql_compare.txt"))
        {
            writer.WriteLine("10000 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 10000 rows: {0} milliseconds", AdapterFillLargeTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 10000 rows: {0} milliseconds", readerLoadLargeTableTime);
            writer.WriteLine("1000 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 1000 rows: {0} milliseconds", AdapterFillMediumTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 1000 rows: {0} milliseconds", readerLoadMediumTableTime);
            writer.WriteLine("100 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 100 rows: {0} milliseconds", AdapterFillSmallTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 100 rows: {0} milliseconds", readerLoadSmallTableTime);
            writer.WriteLine("10 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 10 rows: {0} milliseconds", AdapterFillTinyTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 10 rows: {0} milliseconds", readerLoadTinyTableTime);

        }
        Process.Start("result_sql_compare.txt");
    }

    private long MeasureExecutionTimeMethod(SqlConnection conn, string query, Action<SqlConnection, string> Method)
    {
        long time; // know C#
        // execute single read step outside measurement time, to warm up cache or whatever
        Method(conn, query);
        // start timing
        time = Environment.TickCount;
        for (int i = 0; i < 100; i++)
        {
            Method(conn, query);
        }
        // return time in milliseconds
        return Environment.TickCount - time;
    }

    private void ExecuteDataAdapterFillStep(SqlConnection conn, string query)
    {
        DataTable tab = new DataTable();
        conn.Open();
        using (SqlDataAdapter comm = new SqlDataAdapter(query, conn))
        {
            // Adapter fill table function
            comm.Fill(tab);
        }
        conn.Close();
    }

    private void ExecuteSqlReaderLoadStep(SqlConnection conn, string query)
    {
        DataTable tab = new DataTable();
        conn.Open();
        using (SqlCommand comm = new SqlCommand(query, conn))
        {
            using (SqlDataReader reader = comm.ExecuteReader())
            {
                // IDataReader Load function
                tab.Load(reader);
            }
        }
        conn.Close();
    }

Results:

10000 rows:
Sql Data Adapter 100 times table fill speed 10000 rows: 11782 milliseconds
Sql Data Reader  100 times table load speed 10000 rows: 26047 milliseconds
1000 rows:
Sql Data Adapter 100 times table fill speed 1000 rows: 984  milliseconds
Sql Data Reader  100 times table load speed 1000 rows: 2031 milliseconds
100 rows:
Sql Data Adapter 100 times table fill speed 100 rows: 125 milliseconds
Sql Data Reader  100 times table load speed 100 rows: 235 milliseconds
10 rows:
Sql Data Adapter 100 times table fill speed 10 rows: 32 milliseconds
Sql Data Reader  100 times table load speed 10 rows: 93 milliseconds

For performance issues, using the SqlDataAdapter.Fill method is far more efficient. So unless you want to shoot yourself in the foot use that. It works faster for small and large data sets.

You probably finally realized this between posting this question and today, but the very nature of selectors makes it impossible to navigate through hierarchically unrelated HTML elements.

Or, to put it simply, since you said in your comment that

there are no uniform parent containers

... it's just not possible with selectors alone, without modifying the markup in some way as shown by the other answers.

You have to use the jQuery .eq() solution.

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

The answer of your question is that you must set the same value in Primary and secondary key. Thanks

List<WebElement> myElements = driver.findElements(By.xpath("some/path//a"));
        System.out.println("Size of List: "+myElements.size());
        for(WebElement e : myElements) 
        {        
            System.out.print("Text within the Anchor tab"+e.getText()+"\t");
            System.out.println("Anchor: "+e.getAttribute("href"));
        }

//NOTE: "//a" will give you all the anchors there on after the point your XPATH has reached.

You could do this if firstname and surname are separated by space:

SELECT SUBSTRING(FirstAndSurnameCol, 0, CHARINDEX(' ', FirstAndSurnameCol)) Firstname,
SUBSTRING(FirstAndSurnameCol, CHARINDEX(' ', FirstAndSurnameCol)+1, LEN(FirstAndSurnameCol)) Surname FROM ...

edit: Manual installation and use of setuptools is not the standard process anymore.

If you're running Python 2.7.9+ or Python 3.4+

Congrats, you should already have pip installed. If you do not, read onward.

If you're running a Unix-like System

You can usually install the package for pip through your package manager if your version of Python is older than 2.7.9 or 3.4, or if your system did not include it for whatever reason.

Instructions for some of the more common distros follow.

Installing on Debian (Wheezy and newer) and Ubuntu (Trusty Tahr and newer) for Python 2.x

Run the following command from a terminal:

sudo apt-get install python-pip 

Installing on Debian (Wheezy and newer) and Ubuntu (Trusty Tahr and newer) for Python 3.x

Run the following command from a terminal:

sudo apt-get install python3-pip

On a fresh Debian/Ubuntu install, the package may not be found until you do:

sudo apt-get update

Installing pip on CentOS 7 for Python 2.x

On CentOS 7, you have to install setup tools first, and then use that to install pip, as there is no direct package for it.

sudo yum install python-setuptools
sudo easy_install pip

Installing pip on CentOS 7 for Python 3.x

Assuming you installed Python 3.4 from EPEL, you can install Python 3's setup tools and use it to install pip.

# First command requires you to have enabled EPEL for CentOS7
sudo yum install python34-setuptools
sudo easy_install pip

If your Unix/Linux distro doesn't have it in package repos

Install using the manual way detailed below.

The manual way

If you want to do it the manual way, the now-recommended method is to install using the get-pip.py script from pip's installation instructions.

Install pip

To install pip, securely download get-pip.py

Then run the following (which may require administrator access):

python get-pip.py 

If setuptools is not already installed, get-pip.py will install setuptools for you.

I faced the same problem, but when i was lokking for php.ini and php.exe i found php.exe at C:\UwAmp\bin\php\php-5.4.15 when php.ini at C:\UwAmp\bin\apache. I just copy php.ini at C:\UwAmp\bin\php\php-5.4.15 and Uncomment the line extension=php_openssl.dll and it fixed.

For Wine users:... For reasons having to do with "unimplemented" (as in: the "find" command and the "/D" switch to "copy"), it appears that you have to cheat a bit more to get Android SDK to see JDK in Wine.

However, I have passed the hurdles and am (I suppose) obliged to share something (anything) that worked:

1. What is responsible for finding Java is the script "tools/lib/find_java.bat". In the beginning of that file, add:

   set java_exe=%JAVA_HOME%/bin/java.exe goto :EOF

   2. To circumvent the "copy /D not implemented" issue, in "tools/android.bat" comment out (with "rem") the lines from just after

   :MkTempCopy

to just before

:EndTempCopy

You should now (if you've set JAVA_HOME) be able to run android.bat and install the SDK parts you need.

I have had a similar scenario where I needed to set the focus on a text box within a panel when the panel was shown. The panel was loaded on application startup, so I couldn't set the focus in the constructor. As the panel wasn't being loaded or being given focus on show, this meant that I had no event to fire the focus request from.

To solve this, I added a global method to my main that called a method in the panel that invoked requestFocusInWindow() on the text area. I put the call to the global method in the button that showed the panel, after the call to show. This meant that the panel would be shown and then the text area assigned the focus after showing the panel. Hope that makes sense and helps!

Also, you can edit most of the auto-generated code by right clicking on the object in design view and selecting customize code, however I don't think that it allows you to edit panels.

I only just noticed this question, and wanted to add my $.02 to this.

In case of Java, this is not actually an option. The "unreachable code" error doesn't come from the fact that JVM developers thought to protect developers from anything, or be extra vigilant, but from the requirements of the JVM specification.

Both Java compiler, and JVM, use what is called "stack maps" - a definite information about all of the items on the stack, as allocated for the current method. The type of each and every slot of the stack must be known, so that a JVM instruction doesn't mistreat item of one type for another type. This is mostly important for preventing having a numeric value ever being used as a pointer. It's possible, using Java assembly, to try to push/store a number, but then pop/load an object reference. However, JVM will reject this code during class validation,- that is when stack maps are being created and tested for consistency.

To verify the stack maps, the VM has to walk through all the code paths that exist in a method, and make sure that no matter which code path will ever be executed, the stack data for every instruction agrees with what any previous code has pushed/stored in the stack. So, in simple case of:

Object a;
if (something) { a = new Object(); } else { a = new String(); }
System.out.println(a);

at line 3, JVM will check that both branches of 'if' have only stored into a (which is just local var#0) something that is compatible with Object (since that's how code from line 3 and on will treat local var#0).

When compiler gets to an unreachable code, it doesn't quite know what state the stack might be at that point, so it can't verify its state. It can't quite compile the code anymore at that point, as it can't keep track of local variables either, so instead of leaving this ambiguity in the class file, it produces a fatal error.

Of course a simple condition like if (1<2) will fool it, but it's not really fooling - it's giving it a potential branch that can lead to the code, and at least both the compiler and the VM can determine, how the stack items can be used from there on.

P.S. I don't know what .NET does in this case, but I believe it will fail compilation as well. This normally will not be a problem for any machine code compilers (C, C++, Obj-C, etc.)

If you read the help file for ?boxplot, you'll see there is a names= parameter.

     boxplot(apple, banana, watermelon, names=c("apple","banana","watermelon"))

You want to pass the function object hi to your loop() function, not the result of a call to hi() (which is None since hi() doesn't return anything).

So try this:

>>> loop(hi, 5)
hi
hi
hi
hi
hi

Perhaps this will help you understand better:

>>> print hi()
hi
None
>>> print hi
<function hi at 0x0000000002422648>

I had a similar problem with a small difference: some a.category_id are not in b and some b.category_id are not in a.
To solve this problem just adapt the excelent answer from beny23 to

select a.col1, b.col2, a.col3, b.col4, a.category_id 
from items_a a
LEFT OUTER JOIN
items_b b 
on a.category_id = b.category_id

Hope this helps someone.
Regards.

Here is the way that I've followed,

int[] selRows = ((GridView)gridControl1.MainView).GetSelectedRows();
DataRowView selRow = (DataRowView)(((GridView)gridControl1.MainView).GetRow(selRows[0]));
txtName.Text = selRow["name"].ToString();

Also you can iterate through selected rows using the selRows array. Here the code describes how to get data only from first selected row. You can insert these code lines to click event of the grid.

You have to do it step by step if you don't want a TypeError because if one of the members is null or undefined, and you try to access a member, an exception will be thrown.

You can either simply catch the exception, or make a function to test the existence of multiple levels, something like this:

function checkNested(obj /*, level1, level2, ... levelN*/) {
  var args = Array.prototype.slice.call(arguments, 1);

  for (var i = 0; i < args.length; i++) {
    if (!obj || !obj.hasOwnProperty(args[i])) {
      return false;
    }
    obj = obj[args[i]];
  }
  return true;
}

var test = {level1:{level2:{level3:'level3'}} };

checkNested(test, 'level1', 'level2', 'level3'); // true
checkNested(test, 'level1', 'level2', 'foo'); // false

ES6 UPDATE:

Here is a shorter version of the original function, using ES6 features and recursion (it's also in proper tail call form):

function checkNested(obj, level,  ...rest) {
  if (obj === undefined) return false
  if (rest.length == 0 && obj.hasOwnProperty(level)) return true
  return checkNested(obj[level], ...rest)
}

However, if you want to get the value of a nested property and not only check its existence, here is a simple one-line function:

function getNested(obj, ...args) {_x000D_
  return args.reduce((obj, level) => obj && obj[level], obj)_x000D_
}_x000D_
_x000D_
const test = { level1:{ level2:{ level3:'level3'} } };_x000D_
console.log(getNested(test, 'level1', 'level2', 'level3')); // 'level3'_x000D_
console.log(getNested(test, 'level1', 'level2', 'level3', 'length')); // 6_x000D_
console.log(getNested(test, 'level1', 'level2', 'foo')); // undefined_x000D_
console.log(getNested(test, 'a', 'b')); // undefined

The above function allows you to get the value of nested properties, otherwise will return undefined.

UPDATE 2019-10-17:

The optional chaining proposal reached Stage 3 on the ECMAScript committee process, this will allow you to safely access deeply nested properties, by using the token ?., the new optional chaining operator:

const value = obj?.level1?.level2?.level3 

If any of the levels accessed is null or undefined the expression will resolve to undefined by itself.

The proposal also allows you to handle method calls safely:

obj?.level1?.method();

The above expression will produce undefined if obj, obj.level1, or obj.level1.method are null or undefined, otherwise it will call the function.

You can start playing with this feature with Babel using the optional chaining plugin.

Since Babel 7.8.0, ES2020 is supported by default

Check this example on the Babel REPL.

UPDATE: December 2019

The optional chaining proposal finally reached Stage 4 in the December 2019 meeting of the TC39 committee. This means this feature will be part of the ECMAScript 2020 Standard.

If you want to create the popup window through jQuery then you'll need to use a plugin. This one seems like it will do what you want:

http://rip747.github.com/popupwindow/

Alternately, you can always use JavaScript's window.open function.

Note that with either approach, the new window must be opened in response to user input/action (so for instance, a click on a link or button). Otherwise the browser's popup blocker will just block the popup.

Try this :

open the terminal and type this command : sudo gedit /etc/mysql/my.cnf

Paste the line in my.cnf file: set-variable=max_connections=500

Looks like you've not encapsulated your string properly. Try this:

INSERT INTO custorder VALUES ('Kevin','yes'), STR_TO_DATE('1-01-2012', '%d-%m-%Y');

Alternatively, you can do the following but it is not recommended. Make sure that you use STR_TO-DATE it is because when you are developing web applications you have to explicitly convert String to Date which is annoying. Use first One.

INSERT INTO custorder VALUES ('Kevin','yes'), '2012-01-01';

I'm not confident that the above SQL is valid, however, and you may want to move the date part into the brackets. If you can provide the exact error you're getting, I might be able to more directly help with the issue.

If you use FastCGI try:

fastcgi_hide_header X-Powered-By;

if it is just a format issue use ToShortDateString()

Try

$(document).ready(function(){
    //Register click events to all checkboxes inside question element
    $(document).on('click', '.question input:checkbox', function() {
        //Find the next answer element to the question and based on the checked status call either show or hide method
        $(this).closest('.question').next('.answer')[this.checked? 'show' : 'hide']()
    });

});

Demo: Fiddle

Or

$(document).ready(function(){
    //Register click events to all checkboxes inside question element
    $(document).on('click', '.question input:checkbox', function() {
        //Find the next answer element to the question and based on the checked status call either show or hide method
        var answer = $(this).closest('.question').next('.answer');

        if(this.checked){
            answer.show(300);
        } else {
            answer.hide(300);
        }
    });

});

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

Test-Path may give odd answer. E.g. "Test-Path c:\temp\ -PathType leaf" gives false, but "Test-Path c:\temp* -PathType leaf" gives true. Sad :(

NullPointerExceptions are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.

Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerExceptions is accidentally declaring an object with local scope when there is an instance variable with the same name.

In your case, the exception occurred in your constructor for Workshop on line 75. <init> means the constructor for a class. If you look on that line in your code, you'll see the line

denimjeansButton.addItemListener(this);

There are fairly clearly two objects on this line: denimjeansButton and this. this is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this. denimjeansButton is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton or instantiate it.

For me it was due to react-native version in dependency section of package.json file. It was:

"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "~0.55.0"
}

I chaged it to:

"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "0.52.0"
}

Now it works fine.

<div ng-bind-html="myText"></div> No need to put into html {{}} interpolation tags like you did {{myText}}.

and don't forget to use ngSanitize in module like e.g. var app = angular.module("myApp", ['ngSanitize']);

and add its cdn dependency in index.html page https://cdnjs.com/libraries/angular-sanitize

Factory and Service is a just wrapper of a provider.

Factory

Factory can return anything which can be a class(constructor function), instance of class, string, number or boolean. If you return a constructor function, you can instantiate in your controller.

 myApp.factory('myFactory', function () {

  // any logic here..

  // Return any thing. Here it is object
  return {
    name: 'Joe'
  }
}

Service

Service does not need to return anything. But you have to assign everything in this variable. Because service will create instance by default and use that as a base object.

myApp.service('myService', function () {

  // any logic here..

  this.name = 'Joe';
}

Actual angularjs code behind the service

function service(name, constructor) {
    return factory(name, ['$injector', function($injector) {
        return $injector.instantiate(constructor);
    }]);
}

It just a wrapper around the factory. If you return something from service, then it will behave like Factory.

IMPORTANT: The return result from Factory and Service will be cache and same will be returned for all controllers.

When should i use them?

Factory is mostly preferable in all cases. It can be used when you have constructor function which needs to be instantiated in different controllers.

Service is a kind of Singleton Object. The Object return from Service will be same for all controller. It can be used when you want to have single object for entire application. Eg: Authenticated user details.

Answer for 1.:

You should be able to manually build an expression tree that can be passed into OrderBy using the name as a string. Or you could use reflection as suggested in another answer, which might be less work.

Edit: Here is a working example of building an expression tree manually. (Sorting on X.Value, when only knowing the name "Value" of the property). You could (should) build a generic method for doing it.

using System;
using System.Linq;
using System.Linq.Expressions;

class Program
{
    private static readonly Random rand = new Random();
    static void Main(string[] args)
    {
        var randX = from n in Enumerable.Range(0, 100)
                    select new X { Value = rand.Next(1000) };

        ParameterExpression pe = Expression.Parameter(typeof(X), "value");
        var expression = Expression.Property(pe, "Value");
        var exp = Expression.Lambda<Func<X, int>>(expression, pe).Compile();

        foreach (var n in randX.OrderBy(exp))
            Console.WriteLine(n.Value);
    }

    public class X
    {
        public int Value { get; set; }
    }
}

Building an expression tree requires you to know the particpating types, however. That might or might not be a problem in your usage scenario. If you don't know what type you should be sorting on, it will propably be easier using reflection.

Answer for 2.:

Yes, since Comparer<T>.Default will be used for the comparison, if you do not explicitly define the comparer.

You can also just pass the keys and values of the dictionary to the new dataframe, like so:

import pandas as pd

myDict = {<the_dict_from_your_example>]
df = pd.DataFrame()
df['Date'] = myDict.keys()
df['DateValue'] = myDict.values()

Try adding JSON.stringify(result) to convert the JS Object into a JSON string.

From your code I can see you are logging the result in error which is called if the AJAX request fails, so I'm not sure how you'd go about accessing the id/name/etc. then (you are checking for success inside the error condition!).

Note that if you use Chrome's console you should be able to browse through the object without having to stringify the JSON, which makes it easier to debug.

Another way is to open Visual Studio Code from a terminal with the virtualenv set and need to perform F1 Python: Select Interpreter and select the required virtualenv.

Using context object you can get LayoutInflater from following code

LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

The error message indicates a problem with the locale setting. To fix this as indicated by other answers you need to modify your locale.

On Mac OS X Sierra I found that the best way to do this was to modify the ~/bash_profile file as follows:

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

This change will not be immediately evident in your current cli session unless you reload the bash profile by using: source ~/.bash_profile.

This answer is pretty close to answers that I've posted to other non-identical, non-duplicate questions (i.e. not related to pipenv) but which happen to require the same solution.

To the moderator: With respect; my previous answer got deleted for this reason but I feel that was a bit silly because really this answer applies almost whenever the error is "problem with locale"... but there are a number of differing situations, languages, and environments which could trigger that error.

Thus it A) doesn't make sense to mark the questions as duplicates and B) doesn't make sense to tailor the answer either because the fix is very simple, is the same in each case and does not benefit from ornamentation.

I had this problem. I think that it was caused by the socket getting opened and no data arriving within a short time after the open. I was reading from a serial to ethernet box called a Devicemaster. I changed the Devicemaster port setting from "connect always" to "connect on data" and the problem disappeared. I have great respect for Hans Passant but I do not agree that this is an error code that you can easily solve by scrutinizing code.

According the documentaion hide / toggle should work. But it don't.

Here is how I did it

$('#modal-id').modal('toggle'); //Hide the modal dialog
$('.modal-backdrop').remove(); //Hide the backdrop
$("body").removeClass( "modal-open" ); //Put scroll back on the Body

I've used this method (reported here )

export class AppComponent {

  constructor() {
    if(document.getElementById("testScript"))
      document.getElementById("testScript").remove();
    var testScript = document.createElement("script");
    testScript.setAttribute("id", "testScript");
    testScript.setAttribute("src", "assets/js/test.js");
    document.body.appendChild(testScript);
  }
}

it worked for me since I wanted to execute a javascript file AFTER THE COMPONENT RENDERED.

Lists represent a sequential ordering of elements. Maps are used to represent a collection of key / value pairs.

While you could use a map as a list, there are some definite downsides of doing so.

Maintaining order: - A list by definition is ordered. You add items and then you are able to iterate back through the list in the order that you inserted the items. When you add items to a HashMap, you are not guaranteed to retrieve the items in the same order you put them in. There are subclasses of HashMap like LinkedHashMap that will maintain the order, but in general order is not guaranteed with a Map.

Key/Value semantics: - The purpose of a map is to store items based on a key that can be used to retrieve the item at a later point. Similar functionality can only be achieved with a list in the limited case where the key happens to be the position in the list.

Code readability Consider the following examples.

    // Adding to a List
    list.add(myObject);         // adds to the end of the list
    map.put(myKey, myObject);   // sure, you can do this, but what is myKey?
    map.put("1", myObject);     // you could use the position as a key but why?

    // Iterating through the items
    for (Object o : myList)           // nice and easy
    for (Object o : myMap.values())   // more code and the order is not guaranteed

Collection functionality Some great utility functions are available for lists via the Collections class. For example ...

    // Randomize the list
    Collections.shuffle(myList);

    // Sort the list
    Collections.sort(myList, myComparator);  

Hope this helps,

ok, so my problem was that I tried to install the package with yum which is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories.

But I'm using ubuntu and The usual way to install packages on the command line in Ubuntu is with apt-get. so the right command was:

sudo apt-get install libstdc++.i686

According to a note in the CSS 2.1 spec, the specification “does not fully define the interaction of :before and :after with replaced elements (such as IMG in HTML). This will be defined in more detail in a future specification.” Although input is not really a replaced element any more, the basic situation has not changed: the effect of :before and :after on it in unspecified and generally has no effect.

The solution is to find a different approach to the problem you are trying to address this way. Putting generated content into a text input control would be very misleading: to the user, it would appear to be part of the initial value in the control, but it cannot be modified – so it would appear to be something forced at the start of the control, but yet it would not be submitted as part of form data.

You can do checks using lookarounds:

^(?=.*\bjack\b)(?=.*\bjames\b).*$

Test it.

This approach has the advantage that you can easily specify multiple conditions.

^(?=.*\bjack\b)(?=.*\bjames\b)(?=.*\bjason\b)(?=.*\bjules\b).*$

This would work for BMP and SIP/SMP characters.

    String.prototype.lengthInUtf8 = function() {
        var asciiLength = this.match(/[\u0000-\u007f]/g) ? this.match(/[\u0000-\u007f]/g).length : 0;
        var multiByteLength = encodeURI(this.replace(/[\u0000-\u007f]/g)).match(/%/g) ? encodeURI(this.replace(/[\u0000-\u007f]/g, '')).match(/%/g).length : 0;
        return asciiLength + multiByteLength;
    }

    'test'.lengthInUtf8();
    // returns 4
    '\u{2f894}'.lengthInUtf8();
    // returns 4
    '???? ?????'.lengthInUtf8();
    // returns 19, each Arabic/Persian alphabet character takes 2 bytes. 
    '??,JavaScript ??'.lengthInUtf8();
    // returns 26, each Chinese character/punctuation takes 3 bytes. 

You just missed an extra pair of brackets for the "OR" symbol. The following should do the trick:

([0-9]+)\s+((\bseconds\b)|(\bminutes\b))

Without those you were either matching a number followed by seconds OR just the word minutes

I used :

export PATH=$PATH:/Library/PostgreSQL/9.6/bin

pip install psycopg2

I found a way to solve this problem, but this may not be very grace, but the effect is not bad.

Its principle is to replace the spaces of each line to the fixed-width ImageSpan (the color is transparent).

public static void justify(final TextView textView) {

    final AtomicBoolean isJustify = new AtomicBoolean(false);

    final String textString = textView.getText().toString();

    final TextPaint textPaint = textView.getPaint();

    final SpannableStringBuilder builder = new SpannableStringBuilder();

    textView.post(new Runnable() {
        @Override
        public void run() {

            if (!isJustify.get()) {

                final int lineCount = textView.getLineCount();
                final int textViewWidth = textView.getWidth();

                for (int i = 0; i < lineCount; i++) {

                    int lineStart = textView.getLayout().getLineStart(i);
                    int lineEnd = textView.getLayout().getLineEnd(i);

                    String lineString = textString.substring(lineStart, lineEnd);

                    if (i == lineCount - 1) {
                        builder.append(new SpannableString(lineString));
                        break;
                    }

                    String trimSpaceText = lineString.trim();
                    String removeSpaceText = lineString.replaceAll(" ", "");

                    float removeSpaceWidth = textPaint.measureText(removeSpaceText);
                    float spaceCount = trimSpaceText.length() - removeSpaceText.length();

                    float eachSpaceWidth = (textViewWidth - removeSpaceWidth) / spaceCount;

                    SpannableString spannableString = new SpannableString(lineString);
                    for (int j = 0; j < trimSpaceText.length(); j++) {
                        char c = trimSpaceText.charAt(j);
                        if (c == ' ') {
                            Drawable drawable = new ColorDrawable(0x00ffffff);
                            drawable.setBounds(0, 0, (int) eachSpaceWidth, 0);
                            ImageSpan span = new ImageSpan(drawable);
                            spannableString.setSpan(span, j, j + 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
                        }
                    }

                    builder.append(spannableString);
                }

                textView.setText(builder);
                isJustify.set(true);
            }
        }
    });
}

I put the code on GitHub: https://github.com/twiceyuan/TextJustification

Overview:

In combination of answers of @Cassian and @Hllitec and from https://stackoverflow.com/a/42706309/1001717 here my solution, where I put (only!) the checksum value into a variable for further processing:

for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i

To test the output you can add a piped echo command with the var:

for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i | echo %myVar%

A bit off-topic, but FYI: I used this before uploading my NuGet package to Artifactory. BTW. as alternative you can use JFrog CLI, where checksum is calculated automatically.

If you are using wampserver 3 (recommended, works with no configuration usually)

• click wampserver icon > apache > service administration > install service
• click wampserver icon > mysql > service administration > install service
• click wampserver icon > mariadb > service administration > install service
• click wampserver icon > restart all services

if this doesnt fix it, try:

• right click wampserver icon > Tools > Check httpd.conf syntax (then fix the issue it identifies and restart all services, likely it's bad syntax in your virtual hosts file)

• right click wampserver icon > Tools > test port 80 (you likely have skype turned on or something else, turn it off and restart all services)

If this doesnt fix it, maybe have a windows conflict:

• Upgraded to Windows 10 and now WAMP won't work)

If this doesnt fix it:

• right click wampserver icon > tools
  • check all of those for clues

There is Pageheap.exe part of the debugging tools for Windows. It's free and is basically a custom memory allocator/deallocator.

See http://support.microsoft.com/kb/286470

You are returning a reference to ret which is a variable on the stack.

As others have said,

new String[0]

will indeed create an empty array. However, there's one nice thing about arrays - their size can't change, so you can always use the same empty array reference. So in your code, you can use:

private static final String[] EMPTY_ARRAY = new String[0];

and then just return EMPTY_ARRAY each time you need it - there's no need to create a new object each time.

Your method showFile() declares that it can throw an IOException. Since this is a checked exception, any call to showFile() method must handle the exception somehow. One option is to wrap the call to showFile() in a try-catch block.

 try {
     showFile();
 }
 catch(IOException e) {
    // Code to handle an IOException here
 }

SELECT
  AGE('2012-03-05', '2010-04-01'),
  DATE_PART('year', AGE('2012-03-05', '2010-04-01')) AS years,
  DATE_PART('month', AGE('2012-03-05', '2010-04-01')) AS months,
  DATE_PART('day', AGE('2012-03-05', '2010-04-01')) AS days;

This will give you full years, month, days ... between two dates:

          age          | years | months | days
-----------------------+-------+--------+------
 1 year 11 mons 4 days |     1 |     11 |    4

More detailed datediff information.

There is another solution. The next code is bad (although I think pandas needs this feature):

import pandas as pd

# empty dataframe
a = pd.DataFrame()
a.loc[0] = {'first': 111, 'second': 222}

But the next code runs fine:

import pandas as pd

# empty dataframe
a = pd.DataFrame()
a = a.append(pd.Series({'first': 111, 'second': 222}, name=0))

Start another activity from this activity pass parameters via Bundle Object

Intent intent = new Intent(getBaseContext(), YourActivity.class);
intent.putExtra("USER_NAME", "[email protected]");
startActivity(intent);

Retrieve on another activity (YourActivity)

String s = getIntent().getStringExtra("USER_NAME");

This is ok for simple kind data type. But if u want to pass complex data in between activity u need to serialize it first.

Here we have Employee Model

class Employee{
    private String empId;
    private int age;
    print Double salary;

    getters...
    setters...
}

You can use Gson lib provided by google to serialize the complex data like this

String strEmp = new Gson().toJson(emp);
Intent intent = new Intent(getBaseContext(), YourActivity.class);
intent.putExtra("EMP", strEmp);
startActivity(intent);

Bundle bundle = getIntent().getExtras();
String empStr = bundle.getString("EMP");
            Gson gson = new Gson();
            Type type = new TypeToken<Employee>() {
            }.getType();
            Employee selectedEmp = gson.fromJson(empStr, type);

For brew users

If you're using brew like me and wasted a lot of time searching for the infamous kafka-logs folder, fear no more. (and please do let me know if that works for you and multiple different versions of Homebrew, Kafka etc :) )

You're probably going to find it under:

Location:

/usr/local/var/lib/kafka-logs

How to actually find that path

(this is also helpful for basically every app you install through brew)

1) brew services list

kafka started matbhz /Users/matbhz/Library/LaunchAgents/homebrew.mxcl.kafka.plist

2) Open and read that plist you found above

3) Find the line defining server.properties location open it, in my case:

• /usr/local/etc/kafka/server.properties

4) Look for the log.dirs line:

log.dirs=/usr/local/var/lib/kafka-logs

5) Go to that location and delete the logs for the topics you wish

6) Restart Kafka with brew services restart kafka

It is a viable way to use std::vector as an intermediate container:

QString dataSrc("FooBar");
QString databa = dataSrc.toUtf8();
std::vector<char> data(databa.begin(), databa.end());
char* pDataChar = data.data();

you can simply use this:

Map<String, String[]> parameters = request.getParameterMap();

That should work fine

Using pure Java 8

Assumming you want to extract param "v" from url:

             String paramV = Stream.of(url.split("?")[1].split("&"))
                        .map(kv -> kv.split("="))
                        .filter(kv -> "v".equalsIgnoreCase(kv[0]))
                        .map(kv -> kv[1])
                        .findFirst()
                        .orElse("");

What you're talking about is becoming a payment service provider. I have been there and done that. It was a lot easier about 10 years ago than it is now, but if you have a phenomenal amount of time, money and patience available, it is still possible.

You will need to contact an acquiring bank. You didnt say what region of the world you are in, but by this I dont mean a local bank branch. Each major bank will generally have a separate card acquiring arm. So here in the UK we have (eg) Natwest bank, which uses Streamline (or Worldpay) as its acquiring arm. In total even though we have scores of major banks, they all end up using one of five or so card acquirers.

Happily, all UK card acquirers use a standard protocol for communication of authorisation requests, and end of day settlement. You will find minor quirks where some acquiring banks support some features and have slightly different syntax, but the differences are fairly minor. The UK standards are published by the Association for Payment Clearing Services (APACS) (which is now known as the UKPA). The standards are still commonly referred to as APACS 30 (authorization) and APACS 29 (settlement), but are now formally known as APACS 70 (books 1 through 7).

Although the APACS standard is widely supported across the UK (Amex and Discover accept messages in this format too) it is not used in other countries - each country has it's own - for example: Carte Bancaire in France, CartaSi in Italy, Sistema 4B in Spain, Dankort in Denmark etc. An effort is under way to unify the protocols across Europe - see EPAS.org

Communicating with the acquiring bank can be done a number of ways. Again though, it will depend on your region. In the UK (and most of Europe) we have one communications gateway that provides connectivity to all the major acquirers, they are called TNS and there are dozens of ways of communicating through them to the acquiring bank, from dialup 9600 baud modems, ISDN, HTTPS, VPN or dedicated line. Ultimately the authorisation request will be converted to X25 protocol, which is the protocol used by these acquiring banks when communicating with each other.

In summary then: it all depends on your region.

• Contact a major bank and try to get through to their card acquiring arm.
• Explain that you're setting up as a payment service provider, and request details on comms format for authorization requests and end of day settlement files
• Set up a test merchant account and develop auth/settlement software and go through the accreditation process. Most acquirers help you through this process for free, but when you want to register as an accredited PSP some will request a fee.
• you will need to comply with some regulations too, for example you may need to register as a payment institution

Once you are registered and accredited you'll then be able to accept customers and set up merchant accounts on behalf of the bank/s you're accredited against (bearing in mind that each acquirer will generally support multiple banks). Rinse and repeat with other acquirers as you see necessary.

Beyond that you have lots of other issues, mainly dealing with PCI-DSS. Thats a whole other topic and there are already some q&a's on this site regarding that. Like I say, its a phenomenal undertaking - most likely a multi-year project even for a reasonably sized team, but its certainly possible.

private static String readAll(Reader rd) throws IOException {
    StringBuilder sb = new StringBuilder();
    int cp;
    while ((cp = rd.read()) != -1) {
      sb.append((char) cp);
    }
    return sb.toString();
  }

 String jsonText = readAll(inputofyourjsonstream);
 JSONObject json = new JSONObject(jsonText);
 JSONArray arr = json.getJSONArray("Compemployes");

Your arr would looks like: [ { "id":1001, "name":"jhon" }, { "id":1002, "name":"jhon" } ] You can use:

arr.getJSONObject(index)

to get the objects inside of the array.

byte test[] = new byte[3];
test[0] = 0x0A;
test[1] = 0xFF;
test[2] = 0x01;

for (byte theByte : test)
{
  System.out.println(Integer.toHexString(theByte));
}

NOTE: test[1] = 0xFF; this wont compile, you cant put 255 (FF) into a byte, java will want to use an int.

you might be able to do...

test[1] = (byte) 0xFF;

I'd test if I was near my IDE (if I was near my IDE I wouln't be on Stackoverflow)

The only way is to use a formula or to format cells. The method i will use will be the following: Add another column next to these values. Then use the following formula:

=HOUR(A1)*60+MINUTE(A1)+SECOND(A1)/60

There are four types of integers based on size:

• short integer: 2 byte
• long integer: 4 byte
• long long integer: 8 byte
• integer: depends upon the compiler (16 bit, 32 bit, or 64 bit)

In my case (I'm using VS 2017) works fine the following simple code:

#include "pch.h"
#include <iostream>
#include <stdlib.h>
#include <time.h>

int main()
{
    srand(time(NULL));

    for (int i = 1000; i > 0; i--) //try it thousand times
    {
        int randnum = (double)rand() / ((double)RAND_MAX + 1);
        std::cout << " rnum: " << rand()%2 ;
    }
} 

Try this:

yAxis: {min: 0, max: 100}

See this jsfiddle example

In AndroidManifest change these :

android:icon="@drawable/icon_name"
android:roundIcon="@drawable/icon_name"

Of course there IS a way to create files without opening. It's as easy as calling os.mknod("newfile.txt"). The only drawback is that this call requires root privileges on OSX.

maybe you need to set your window-size dimension. just like:

options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
options.add_argument('--window-size=1920x1080');

browser = webdriver.Chrome(options=options,executable_path = './chromedriver')

if also not working, try increase window-size dimension.

I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.

I've used Anna-Karenina's answer, and it works almost great with a very serious bug.

If you're using sections, long-pressing the section title will give you a wrong result of pressing the first row on that section, I've added a fixed version below (including the filtering of dummy calls based on the gesture state, per Anna-Karenina suggestion).

- (IBAction)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {

        CGPoint p = [gestureRecognizer locationInView:self.tableView];

        NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
        if (indexPath == nil) {
            NSLog(@"long press on table view but not on a row");
        } else {
            UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
            if (cell.isHighlighted) {
                NSLog(@"long press on table view at section %d row %d", indexPath.section, indexPath.row);
            }
        }
    }
}

Just put "?autoplay=1" in the url the video will autoload.

So your url would be: http://www.youtube.com/embed/JW5meKfy3fY?autoplay=1

In case you wanna disable autoplay, just make 1 to 0 as ?autoplay=0

(I know the question is old, but I think this might be good as a reference for people with similar questions)

If you want to load data from an ASCII/text file (which has the benefit or being more or less human-readable and easy to parse in other software), numpy.loadtxt is probably what you want:

• http://docs.scipy.org/doc/numpy/reference/generated/numpy.loadtxt.html

If you just want to quickly save and load numpy arrays/matrices to and from a file, take a look at numpy.save and numpy.load:

• http://docs.scipy.org/doc/numpy/reference/generated/numpy.save.html
• http://docs.scipy.org/doc/numpy/reference/generated/numpy.load.html

//the parsed time zone offset:
DateTimeFormatter dateFormat = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
String fromDateTimeObj = "2011-01-03T12:00:00.000-0800";
DateTime fromDatetime = dateFormat.withOffsetParsed().parseDateTime(fromDateTimeObj);

You could query the table_privileges table in the information schema:

SELECT table_catalog, table_schema, table_name, privilege_type
FROM   information_schema.table_privileges 
WHERE  grantee = 'MY_USER'

Store them as two fields for phone numbers - a "number" and a "mask" as TinyText types which do not need more than 255 items.

Before we store the files we parse the phone number to get the formatting that has been used and that creates the mask, we then store the number a digits only e.g.

Input: (0123) 456 7890
Number: 01234567890
Mask: (nnnn)_nnn_nnnn

Theoretically this allows us to perform comparison searches on the Number field such as getting all phone numbers that begin with a specific area code, without having to worry how it was input by the users

macgyver offers face detection programs via a simple to use API.

The program below takes a reference to a public image and will return an array of the coordinates and dimensions of any faces detected in the image.

https://askmacgyver.com/explore/program/face-location/5w8J9u4z

The problem you face is that you try to assign the return of imshow (which is an matplotlib.image.AxesImage to an existing axes object.

The correct way of plotting image data to the different axes in axarr would be

f, axarr = plt.subplots(2,2)
axarr[0,0].imshow(image_datas[0])
axarr[0,1].imshow(image_datas[1])
axarr[1,0].imshow(image_datas[2])
axarr[1,1].imshow(image_datas[3])

The concept is the same for all subplots, and in most cases the axes instance provide the same methods than the pyplot (plt) interface. E.g. if ax is one of your subplot axes, for plotting a normal line plot you'd use ax.plot(..) instead of plt.plot(). This can actually be found exactly in the source from the page you link to.

The post is old but I found a perfect CSS for the purpose and I want to share it.

A sticky element toggles between relative and fixed, depending on the scroll position. It is positioned relative until a given offset position is met in the viewport - then it "sticks" in place (like position:fixed).

    div.sticky {
        position: -webkit-sticky; /* Safari */
        position: sticky;
        top: 0;
        background-color: green;
        border: 2px solid #4CAF50;
    }

Source: https://www.w3schools.com/css/css_positioning.asp

// @HostListener('scroll', ['$event']) // for scroll events of the current element
@HostListener('window:scroll', ['$event']) // for window scroll events
onScroll(event) {
  ...
}

or

<div (scroll)="onScroll($event)"></div>

This will do it:

new AWS.S3().getObject({ Bucket: this.awsBucketName, Key: keyName }, function(err, data)
{
    if (!err)
        console.log(data.Body.toString());
});

The reason os.path.join('C:', 'src') is not working as you expect is because of something in the documentation that you linked to:

Note that on Windows, since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.

As ghostdog said, you probably want mypath=os.path.join('c:\\', 'sourcedir')

In CodeIgniter you can store your session value as single or also in array format as below:

If you want store any user’s data in session like userId, userName, userContact etc, then you should store in array:

<?php
$this->load->library('session');
$this->session->set_userdata(array(
'userId'  => $user->userId,
'userName' => $user->userName,
'userContact '  => $user->userContact 
)); 
?>

<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>

That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em' as the measurement, you may want to use other units, like 'px'.

EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:

In your HTML page, containing the <p> tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:

<head>
  <style type="text/css">
    p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>

So above, all <p> elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:

<head>
  <style type="text/css">
    .container p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <div class="container">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
  </div>
  <p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>

In the example above, only the <p> element inside the div, whose class name is 'container', will have the styles applied - and not the <p> element outside the container.

In addition to the above, you can collect your styles together and remove the style element from the <head> tag, replacing it with a <link> tag, which points to an external CSS file. This external file is where you'd now put your <p> tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.

If you work without the JSON library, maybe this will help you out:

Object.prototype.equals = function(b) {
    var a = this;
    for(i in a) {
        if(typeof b[i] == 'undefined') {
            return false;
        }
        if(typeof b[i] == 'object') {
            if(!b[i].equals(a[i])) {
                return false;
            }
        }
        if(b[i] != a[i]) {
            return false;
        }
    }
    for(i in b) {
        if(typeof a[i] == 'undefined') {
            return false;
        }
        if(typeof a[i] == 'object') {
            if(!a[i].equals(b[i])) {
                return false;
            }
        }
        if(a[i] != b[i]) {
            return false;
        }
    }
    return true;
}

var a = {foo:'bar', bar: {blub:'bla'}};
var b = {foo:'bar', bar: {blub:'blob'}};
alert(a.equals(b)); // alert's a false

It compares crash logs retrieved from the device to archived (symbolized to be correct) version of your applications to try to retrieved where on your code the crash occurred.

You could use async functions to get _id field automatically without manipulating data object:

async function save() {
  const data = {
    name: "John"
  }

  await db.collection('users').insertOne(data)

  return data
}

Returns data:

{
  _id: '5dbff150b407cc129ab571ca',
  name: 'John'
}

Just use exception.ToString()

http://msdn.microsoft.com/en-us/library/system.exception.tostring.aspx

The default implementation of ToString obtains the name of the class that threw the current exception, the message, the result of calling ToString on the inner exception, and the result of calling Environment.StackTrace. If any of these members is null, its value is not included in the returned string.

If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not null.

exception.ToString() will also call .ToString() on that exception's inner exception, and so on...

I use the following method in my JavaFX applications.

newWindowButton.setOnMouseClicked((event) -> {
    try {
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("NewWindow.fxml"));
        /* 
         * if "fx:controller" is not set in fxml
         * fxmlLoader.setController(NewWindowController);
         */
        Scene scene = new Scene(fxmlLoader.load(), 600, 400);
        Stage stage = new Stage();
        stage.setTitle("New Window");
        stage.setScene(scene);
        stage.show();
    } catch (IOException e) {
        Logger logger = Logger.getLogger(getClass().getName());
        logger.log(Level.SEVERE, "Failed to create new Window.", e);
    }
});

just set -Dlog4j.configuration=file:log4j.properties worked for me.

log4j then looks for the file log4j.properties in the current working directory of the application.

Remember that log4j.configuration is a URL specification, so add 'file:' in front of your log4j.properties filename if you want to refer to a regular file on the filesystem, i.e. a file not on the classpath!

Initially I specified -Dlog4j.configuration=log4j.properties. However that only works if log4j.properties is on the classpath. When I copied log4j.properties to main/resources in my project and rebuild so that it was copied to the target directory (maven project) this worked as well (or you could package your log4j.properties in your project jars, but that would not allow the user to edit the logger configuration!).

For straight HTML, with no JavaScript required:

<a href="#something">Add '#something' to URL</a>

Or, to take your question more literally, to just add '#' to the URL:

<a href="#">Add '#' to URL</a>

for(n in 1:5) {
  if(n==3) next # skip 3rd iteration and go to next iteration
  cat(n)
}

Another possibility is that you have saved the apk file into application PRIVATE folder and then try to install (by starting an intent from your code). in this case, when you start intent, you get error parsing package. In this case, the raised error is about permission issues. The point is saving the file into private folders is not a good practice, however if you really want to do that, you should write file in MODE_WORL_READABLE when you download it. Please consider that MODE_WORLD_READABLE is deprecated and this solution is not the best as it has some security issues. The best is to save your file in an external storage.

To complete some of the answers here, I had to get the ParametrizedType of MyGenericClass, no matter how high is the hierarchy, with the help of recursion:

private Class<T> getGenericTypeClass() {
        return (Class<T>) (getParametrizedType(getClass())).getActualTypeArguments()[0];
}

private static ParameterizedType getParametrizedType(Class clazz){
    if(clazz.getSuperclass().equals(MyGenericClass.class)){ // check that we are at the top of the hierarchy
        return (ParameterizedType) clazz.getGenericSuperclass();
    } else {
        return getParametrizedType(clazz.getSuperclass());
    }
}

Reading from standard input, write 'code.py' as follows:

import sys

rep = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}

for line in sys.stdin:
    for k, v in rep.iteritems():
        line = line.replace(k, v)
    print line

Then, execute the script with redirection or piping (http://en.wikipedia.org/wiki/Redirection_(computing))

python code.py < infile > outfile

For Bootstrap 4

<hr> still works for a normal divider. However, if you want a divider with text in the middle:

<div class="row">
    <div class="col"><hr></div>
    <div class="col-auto">OR</div>
    <div class="col"><hr></div>
</div>

1. Right click your database in databases section
2. Select "Properties"

Doxygen or Sandcastle help file builder are the primary tools that will extract XML documentation into HTML (and other forms) of external documentation.

Note that you can combine these documentation exporters with documentation generators - as you've discovered, Resharper has some rudimentary helpers, but there are also much more advanced tools to do this specific task, such as GhostDoc (for C#/VB code with XML documentation) or my addin Atomineer Pro Documentation (for C#, C++/CLI, C++, C, VB, Java, JavaScript, TypeScript, JScript, PHP, Unrealscript code containing XML, Doxygen, JavaDoc or Qt documentation).

You can access the same environment variables from groovy using the same names (e.g. JOB_NAME or env.JOB_NAME).

From the documentation:

Environment variables are accessible from Groovy code as env.VARNAME or simply as VARNAME. You can write to such properties as well (only using the env. prefix):

env.MYTOOL_VERSION = '1.33'
node {
  sh '/usr/local/mytool-$MYTOOL_VERSION/bin/start'
}

These definitions will also be available via the REST API during the build or after its completion, and from upstream Pipeline builds using the build step.

For the rest of the documentation, click the "Pipeline Syntax" link from any Pipeline job

A many to many relationship normally has a linking table. Consider this "link" as an entity in its own right and give it a unique id, then send that id in the delete request.

You would have a a REST resource URL like /user/role to handle operations on a user-role "link" entity.

Here's what I did in my values/themes.xml

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="buttonStyle">@style/MyButton</item>
    </style>

    <style name="MyButton" parent="Widget.AppCompat.Button">
        <item name="android:textAllCaps">false</item>
    </style>

I'd say the closest thing to "IF" in CSS are media queries, such as those you can use for responsive design. With media queries, you're saying things like, "If the screen is between 440px and 660px wide, do this". Read more about media queries here: http://www.w3schools.com/cssref/css3_pr_mediaquery.asp, and here's an example of how they look:

@media screen and (max-width: 300px) {
  body {
     background-color: lightblue;
  }
}

That's pretty much the extent of "IF" within CSS, except to move over to SASS/SCSS (as mentioned above).

I think your best bet is to change your classes / IDs within the scripting language, and then treat each of the class/ID options in your CSS. For instance, in PHP, it might be something like:

<?php
  if( A > B ){
echo '<div class="option-a">';
} 
    else{
echo '<div class="option-b">';
}
?>

Then your CSS can be like

.option-a {
background-color:red;
}
.option-b {
background-color:blue;
}

If you are the only the person working on the project, what you can do is:

 git checkout master
 git push origin +HEAD

This will set the tip of origin/master to the same commit as master (and so delete the commits between 41651df and origin/master)

To enable the query log in MAC Machine:

Open the following file:

vi /private/etc/my.cnf

Set the query log url under 'mysqld' section as follows:

[mysqld]

general_log_file=/Users/kumanan/Documents/mysql_query.log

Few machine’s are not logging query properly, So that case you can enable it from MySQL console

mysql> SET global general_log = 1;

OK I found it.

=LARGE($E$4:$E$9;A12)

=large(array, k)

Array Required. The array or range of data for which you want to determine the k-th largest value.

K Required. The position (from the largest) in the array or cell range of data to return.

The Wikipedia page on it is a good place to start.

To sum up:

• float is represented in 32 bits, with 1 sign bit, 8 bits of exponent, and 23 bits of the significand (or what follows from a scientific-notation number: 2.33728*10¹²; 33728 is the significand).

• double is represented in 64 bits, with 1 sign bit, 11 bits of exponent, and 52 bits of significand.

By default, Java uses double to represent its floating-point numerals (so a literal 3.14 is typed double). It's also the data type that will give you a much larger number range, so I would strongly encourage its use over float.

There may be certain libraries that actually force your usage of float, but in general - unless you can guarantee that your result will be small enough to fit in float's prescribed range, then it's best to opt with double.

If you require accuracy - for instance, you can't have a decimal value that is inaccurate (like 1/10 + 2/10), or you're doing anything with currency (for example, representing $10.33 in the system), then use a BigDecimal, which can support an arbitrary amount of precision and handle situations like that elegantly.

I'm not 100% sure this is the only difference, but it is the main difference. It is also recommended to have bi-directional associations by the Hibernate docs:

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/best-practices.html

Specifically:

Prefer bidirectional associations: Unidirectional associations are more difficult to query. In a large application, almost all associations must be navigable in both directions in queries.

I personally have a slight problem with this blanket recommendation -- it seems to me there are cases where a child doesn't have any practical reason to know about its parent (e.g., why does an order item need to know about the order it is associated with?), but I do see value in it a reasonable portion of the time as well. And since the bi-directionality doesn't really hurt anything, I don't find it too objectionable to adhere to.
