VMWare Player is a free alternative to Oracle VirtualBox and Microsoft VirtualPC. As with the mentions of VirtualBox you'll need to create your own images of OS+browser, though. VMWare Player is here: http://www.vmware.com/products/player/

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

Actually, Double.NaN is supported in all .NET versions 2.0 and greater.

Windows: CTRL-SHIFT-J OR F12

Mac: ?-?-J

Dockerfile is a file that contains text commands to assemble an image.

Docker compose is used to run a multi-container environment.

In your specific scenario, if you have multiple services for each technology you mentioned (service 1 using reddis, service 2 using rabbit mq etc), then you can have a Dockerfile for each of the services and a common docker-compose.yml to run all the "Dockerfile" as containers.

If you want them all in a single service, docker-compose will be a viable option.

Not really related match to the original question, but may be someone will find it useful. PermGen is indeed an area in memory where Java used to keep its classes. So, many of us have came across OOM in PermGen, if there were, for example a lot of classes.

Since Java 8, PermGen area has been replaced by MetaSpace area, which is more efficient and is unlimited by default (or more precisely - limited by amount of native memory, depending on 32 or 64 bit jvm and OS virtual memory availability) . However it is possible to tune it in some ways, by for example specifying a max limit for the area. You can find more useful information in this blog post.

We've just come across a very similar issue and I'm now very much a +1 for never using Money except in top level presentation. We have multiple tables (effectively a sales voucher and sales invoice) each of which contains one or more Money fields for historical reasons, and we need to perform a pro-rata calculation to work out how much of the total invoice Tax is relevant to each line on the sales voucher. Our calculation is

vat proportion = total invoice vat x (voucher line value / total invoice value)

This results in a real world money / money calculation which causes scale errors on the division part, which then multiplies up into an incorrect vat proportion. When these values are subsequently added, we end up with a sum of the vat proportions which do not add up to the total invoice value. Had either of the values in the brackets been a decimal (I'm about to cast one of them as such) the vat proportion would be correct.

When the brackets weren't there originally this used to work, I guess because of the larger values involved, it was effectively simulating a higher scale. We added the brackets because it was doing the multiplication first, which was in some rare cases blowing the precision available for the calculation, but this has now caused this much more common error.

I had published the website several times. But one day when I modified some aspx file and then tried to publish the website, it resulted in an empty published folder.

On my workaround, I found a solution.

1. The publishing wizard will reflect any error while publishing but will not copy any file to the destination folder.

2. To find out the file that generates the error just copy the website folder contents to a new folder and start the visual studio with that website.

3. Now when you try to publish it will give you the file name that contains errors.

4. Just rectify the error in the original website folder and try to publish, it will work as it was earlier.

You can use, which will be triggered when the window resizes.

$( window ).bind("resize", function(){
    // Change the width of the div
    $("#yourdiv").width( 600 );
});

If you want a DIV width as percentage of the screen, just use CSS width : 80%;.

Since you already seem to have solved the basic pointer address display, here's how you would check the address of a double pointer:

char **a;
char *b;
char c = 'H';

b = &c;
a = &b;

You would be able to access the address of the double pointer a by doing:

printf("a points at this memory location: %p", a);
printf("which points at this other memory location: %p", *a);

There will be a problem if the instance can be accessed publicly because there could be other requests that might be using the same object instance. It's better to use private/static variable.

in my case, when I added Fragment I git this error.

When I opened THe app build.gradle I saw id("kotlin-android") this plugin in plugins.

just remove it!

I believe you can use...

RESET QUERY CACHE;

...if the user you're running as has reload rights. Alternatively, you can defragment the query cache via...

FLUSH QUERY CACHE;

See the Query Cache Status and Maintenance section of the MySQL manual for more information.

You can only accomplish this with PHP comments.

 <!-- <tr>
      <td><?php //echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php //echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php //echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php //echo $sort_order; ?>" size="1" /></td>
    </tr> -->

The way that PHP and HTML works, it is not able to comment in one swoop unless you do:

<?php

/*

echo <<<ENDHTML
 <tr>
          <td>{$entry_keyword}</td>
          <td><input type="text" name="keyword" value="{echo $keyword}" /></td>
        </tr>
        <tr>
          <td>{$entry_sort_order}</td>
          <td><input name="sort_order" value="{$sort_order}" size="1" /></td>
        </tr>
ENDHTML;

*/
?>

Use

print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))

like this:

>>> my_string = "deadbeef"
>>> print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))
0xde 0xad 0xbe 0xef
>>>

On an unrelated side note ... using string as a variable name even as an example variable name is very bad practice.

Please read the user notes for this method:

If you have a single play that you want to loop over the items, define that list in group_vars/all or somewhere else that makes sense:

all_items:
  - first
  - second
  - third
  - fourth

Then your task can look like this:

  - name: List items or default list
    debug:
      var: item
    with_items: "{{ varlist | default(all_items) }}"

Pass in varlist as a JSON array:

ansible-playbook <playbook_name> --extra-vars='{"varlist": [first,third]}'

Prior to that, you might also want a task that checks that each item in varlist is also in all_items:

  - name: Ensure passed variables are in all_items
    fail:
      msg: "{{ item }} not  in all_items list"
    when: item not in all_items
    with_items: "{{ varlist | default(all_items) }}"

$q="SELECT * FROM projects WHERE YEAR(date) = 2012 AND MONTH(date) = 1;

If expression returns a boolean, you can just return the result of it.

C# 8.0 is the latest version of c#.it is supported only on .NET Core 3.x and newer versions. Many of the newest features require library and runtime features introduced in .NET Core 3.x

On limited version of Linux (like a QNAP (nas) I was working on):

• comm did not exist
• grep -f file1 file2 can cause some problems as said by @ChristopherSchultz and using grep -F -f file1 file2 was really slow (more than 5 minutes - not finished it - over 2-3 seconds with the method below on files over 20MB)

So here is what I did :

sort file1 > file1.sorted
sort file2 > file2.sorted

diff file1.sorted file2.sorted | grep "<" | sed 's/^< *//' > files.diff
diff file1.sorted files.diff | grep "<" | sed 's/^< *//' > files.same.sorted

If files.same.sorted shall have been in same order than the original ones, than add this line for same order than file1 :

awk 'FNR==NR {a[$0]=$0; next}; $0 in a {print a[$0]}' files.same.sorted file1 > files.same

or, for same order than file2 :

awk 'FNR==NR {a[$0]=$0; next}; $0 in a {print a[$0]}' files.same.sorted file2 > files.same

From Wikipedia,

A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases.

There are different types of DBMS products: relational, network and hierarchical. The most widely commonly used type of DBMS today is the Relational Database Management Systems (RDBMS)

DBMS:

• A DBMS is a storage area that persist the data in files.
• There are limitations to store records in a single database file.
• DBMS allows the relations to be established between 2 files.
• Data is stored in flat files with metadata.
• DBMS does not support client / server architecture.
• DBMS does not follow normalization. Only single user can access the data.
• DBMS does not impose integrity constraints.
• ACID properties of database must be implemented by the user or the developer

RDBMS:

• RDBMS stores the data in tabular form.
• It has additional condition for supporting tabular structure or data that enforces relationships among tables.
• RDBMS supports client/server architecture.
• RDBMS follows normalization.
• RDBMS allows simultaneous access of users to data tables.
• RDBMS imposes integrity constraints.
• ACID properties of the database are defined in the integrity constraints.

Have a look at this article for more details.

Use sorted() with a key as follows -

>>> unsorted_list = [['a','b','c','5','d'],['e','f','g','3','h'],['i','j','k','4','m']]
>>> sorted(unsorted_list, key = lambda x: int(x[3]))
[['e', 'f', 'g', '3', 'h'], ['i', 'j', 'k', '4', 'm'], ['a', 'b', 'c', '5', 'd']]

The lambda returns the fourth element of each of the inner lists and the sorted function uses that to sort those list. This assumes that int(elem) will not fail for the list.

Or use itemgetter (As Ashwini's comment pointed out, this method would not work if you have string representations of the numbers, since they are bound to fail somewhere for 2+ digit numbers)

>>> from operator import itemgetter
>>> sorted(unsorted_list, key = itemgetter(3))
[['e', 'f', 'g', '3', 'h'], ['i', 'j', 'k', '4', 'm'], ['a', 'b', 'c', '5', 'd']]

Otherwise we may change the default property configurator name, setting the property spring.config.name=test and then having class-path resource src/test/test.properties our native instance of org.springframework.boot.SpringApplication will be auto-configured from this separated test.properties, ignoring application properties;

Benefit: auto-configuration of tests;

Drawback: exposing "spring.config.name" property at C.I. layer

ref: http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

spring.config.name=application # Config file name

A form is not allowed to be a child element of a table, tbody or tr. Attempting to put one there will tend to cause the browser to move the form to it appears after the table (while leaving its contents — table rows, table cells, inputs, etc — behind).

You can have an entire table inside a form. You can have a form inside a table cell. You cannot have part of a table inside a form.

Use one form around the entire table. Then either use the clicked submit button to determine which row to process (to be quick) or process every row (allowing bulk updates).

HTML 5 introduces the form attribute. This allows you to provide one form per row outside the table and then associate all the form control in a given row with one of those forms using its id.

Note: For <a> elements, omit data-target, and use href="#modalID" instead.

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

After creating Set just convert it to List and get by index from List:

Set<String> stringsSet = new HashSet<>();
stringsSet.add("string1");
stringsSet.add("string2");

List<String> stringsList = new ArrayList<>(stringsSet);
stringsList.get(0); // "string1";
stringsList.get(1); // "string2";

Instead of returning POSITION_NONE and creating all fragments again, you can do as I suggested here: Update ViewPager dynamically?

An excellent explanation can be found here: Generate script in SQL Server Management Studio

Courtesy Ali Issa Here's what you have to do:

1. Right click the database (not the table) and select tasks --> generate scripts
2. Next --> select the requested table/tables (from select specific database objects)
3. Next --> click advanced --> types of data to script = schema and data

If you want to create a script that just generates the tables (no data) you can skip the advanced part of the instructions!

You can define style rules which only apply to specific elements inside your div with id divContainer like this:

#divContainer input { ... }
#divContainer input[type="radio"] { ... }
#divContainer input[type="text"] { ... }
/* etc */

You can use numpy.logical_not to invert the boolean array returned by isin:

In [63]: s = pd.Series(np.arange(10.0))

In [64]: x = range(4, 8)

In [65]: mask = np.logical_not(s.isin(x))

In [66]: s[mask]
Out[66]: 
0    0
1    1
2    2
3    3
8    8
9    9

As given in the comment by Wes McKinney you can also use

s[~s.isin(x)]

No -P needed; -E is sufficient:

grep -E '(^|\s)abc(\s|$)' 

or even without -E:

grep '\(^\|\s\)abc\(\s\|$\)' 

As everybody already have said, you use this(…), which is called an explicit constructor invocation.

However, keep in mind that within such an explicit constructor invocation statement you may not refer to

• any instance variables or
• any instance methods or
• any inner classes declared in this class or any superclass, or
• this or
• super.

As stated in JLS (§8.8.7.1).

Warning!

This answer is now outdated. DOM Level 4 introduced MutationObserver, providing an effective replacement for the deprecated mutation events. See this answer to another question for a better solution than the one presented here. Seriously. Don't poll the DOM every 100 milliseconds; it will waste CPU power and your users will hate you.

Since mutation events were deprecated in 2012, and you have no control over the inserted elements because they are added by someone else's code, your only option is to continuously check for them.

function checkDOMChange()
{
    // check for any new element being inserted here,
    // or a particular node being modified

    // call the function again after 100 milliseconds
    setTimeout( checkDOMChange, 100 );
}

Once this function is called, it will run every 100 milliseconds, which is 1/10 (one tenth) of a second. Unless you need real-time element observation, it should be enough.

It's also worth noting that if IE falls into quirks mode, your jQuery UI components, and other elements, will be positioned incorrectly.

To make sure you don't fall into quirks mode, make sure you set your doctype correctly to the latest HTML5.

<!DOCTYPE html>

Using transitional makes a mess of things. Hopefully this will save someone some time in the future.

I would use NSPredicate:

func isValidEmail(_ email: String) -> Bool {        
    let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

    let emailPred = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
    return emailPred.evaluate(with: email)
}

for versions of Swift earlier than 3.0:

func isValidEmail(email: String) -> Bool {
    let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

    let emailPred = NSPredicate(format:"SELF MATCHES %@", emailRegEx)
    return emailPred.evaluate(with: email)
}

for versions of Swift earlier than 1.2:

func isValidEmail(email: String) -> Bool {
    let emailRegEx = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,64}"

    if let emailPred = NSPredicate(format:"SELF MATCHES %@", emailRegEx) {
        return emailPred.evaluateWithObject(email)
    }
    return false
}

For me it's the simplest way:

selected_date = date(some_year, some_month, some_day)

if selected_date.month == 12: # December
     last_day_selected_month = date(selected_date.year, selected_date.month, 31)
else:
     last_day_selected_month = date(selected_date.year, selected_date.month + 1, 1) - timedelta(days=1)

Very short summarized, I will say that Spring is the "glue" in your application. It's used to integrate different frameworks and your own code.

gt = next Tap gT = previous Tab

Another example for anyone who runs into a problem with types such as Int? and CGFloat?. You simply set you class as a subclass of NSObject and declare your variables as follows e.g:

class Theme : NSObject{

   dynamic var min_images : Int = 0
   dynamic var moreTextSize : CGFloat = 0.0

   func myMethod(){
       self.setValue(value, forKey: "\(min_images)")
   }

}

You can use Cmd command to run Batch file.

Here is my way =>

cmd /c ""Full_Path_Of_Batch_Here.cmd" "

Main and Background Queues

let main = DispatchQueue.main
let background = DispatchQueue.global()
let helper = DispatchQueue(label: "another_thread") 

Working with async and sync threads!

 background.async { //async tasks here } 
 background.sync { //sync tasks here } 

Async threads will work along with the main thread.

Sync threads will block the main thread while executing.

Simply write a query like:

create table new_table as select * from old_table where 1=2;

where new_table is the name of the new table that you want to create and old_table is the name of the existing table whose structure you want to copy, this will copy only structure.

In my opinion, the most elegant and idiomatic way of prepending an element or list to another list, in Python, is using the expansion operator * (also called unpacking operator),

# Initial list
l = [4, 5, 6]

# Modification
l = [1, 2, 3, *l]

Where the resulting list after the modification is [1, 2, 3, 4, 5, 6]

I also like simply combining two lists with the operator +, as shown,

# Prepends [1, 2, 3] to l
l = [1, 2, 3] + l

# Prepends element 42 to l
l = [42] + l

I don't like the other common approach, l.insert(0, value), as it requires a magic number. Moreover, insert() only allows prepending a single element, however the approach above has the same syntax for prepending a single element or multiple elements.

... this syntax is part of ES6 and not something which you can use only in React.It can be used in two different ways; as a spread operator OR as a rest parameter.You can find more from this article: https://www.techiediaries.com/react-spread-operator-props-setstate/

what you have mentioned in the question is something like this, let's assume like this,

    function HelloUser() {
      return <Hello Name="ABC" City="XYZ" />;
    }

with the use of spread operator you can pass props to the component like this.

     function HelloUser() {
       const props = {Name: 'ABC', City: 'XYZ'};
       return <Hello {...props} />;
     }

You can use std::find to get an iterator to a value:

#include <algorithm>
std::vector<int>::iterator position = std::find(myVector.begin(), myVector.end(), 8);
if (position != myVector.end()) // == myVector.end() means the element was not found
    myVector.erase(position);

In my case this was caused by the flexie script which was part of the "CDNJS Selections" app offered by Cloudflare.

According to Cloudflare "This app is being deprecated in March 2015". I turned it off and the message disappeared instantly.

It's security all about. Make sure you have double check your firewall (windows and anti virus) in some cases when you disabled av firewall and restart your computer, automatically windows firewall is active and it's still block your application. Hope this is helpful ..

The long rest in between is due to your keyframe settings. Your current keyframe rules mean that the actual bounce happens only between 40% - 60% of the animation duration (that is, between 1s - 1.5s mark of the animation). Remove those rules and maybe even reduce the animation-duration to suit your needs.

Here is how your original keyframe settings would be interpreted by the browser:

• At 0% (that is, at 0s or start of animation) - translate by 0px in Y axis.
• At 20% (that is, at 0.5s of animation) - translate by 0px in Y axis.
• At 40% (that is, at 1s of animation) - translate by 0px in Y axis.
• At 50% (that is, at 1.25s of animation) - translate by 5px in Y axis. This results in a gradual upward movement.
• At 60% (that is, at 1.5s of animation) - translate by 0px in Y axis. This results in a gradual downward movement.
• At 80% (that is, at 2s of animation) - translate by 0px in Y axis.
• At 100% (that is, at 2.5s or end of animation) - translate by 0px in Y axis.

In your case it is probably taking them in DD-MM-YY format, not MM-DD-YY.

typedef struct Freqamp{
    double freq;
    double amp;
}FREQAMP;

bool struct_cmp_by_freq(FREQAMP a, FREQAMP b)
{
    return a.freq < b.freq;
}

main()
{
    vector <FREQAMP> temp;
    FREQAMP freqAMP;

    freqAMP.freq = 330;
    freqAMP.amp = 117.56;
    temp.push_back(freqAMP);

    freqAMP.freq = 450;
    freqAMP.amp = 99.56;
    temp.push_back(freqAMP);

    freqAMP.freq = 110;
    freqAMP.amp = 106.56;
    temp.push_back(freqAMP);

    sort(temp.begin(),temp.end(), struct_cmp_by_freq);
}

if compare is false, it will do "swap".

If you are using Ubuntu 14.04 ffmpeg is not available. You can install it by using the instructions directly from https://www.ffmpeg.org/download.html.

In short you will have to:

sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg gstreamer0.10-ffmpeg

If this does not work maybe try using sudo apt-get dist-upgrade but this may broke things in your system.

Remove everything after first digit (was adequate for my use case): LEFT(field,PATINDEX('%[0-9]%',field+'0')-1)

Remove trailing digits: LEFT(field,len(field)+1-PATINDEX('%[^0-9]%',reverse('0'+field))

I stumbled across this attempting to solve the same issue. The installation I am working with uses JBOSS and Hibernate, so I had to do this a different way. For the basic case, you should be able to add zeroDateTimeBehavior=convertToNull to your connection URI as per this configuration properties page.

I found other suggestions across the land referring to putting that parameter in your hibernate config:

In hibernate.cfg.xml:

<property name="hibernate.connection.zeroDateTimeBehavior">convertToNull</property>

In hibernate.properties:

hibernate.connection.zeroDateTimeBehavior=convertToNull

But I had to put it in my mysql-ds.xml file for JBOSS as:

<connection-property name="zeroDateTimeBehavior">convertToNull</connection-property>

Hope this helps someone. :)

I know that this isn't an answer to the initial question ... but you often want to clip the inner content of that rounded corner border you just created.

Chris Cavanagh has come up with an excellent way to do just this.

I have tried a couple different approaches to this ... and I think this one rocks.

Here is the xaml below:

this example, I am assuming that all your image files begin with "IMG" and you want to replace "IMG" with "VACATION"

solution : first identified all jpg files and then replace keyword

find . -name '*jpg' -exec bash -c 'echo mv $0 ${0/IMG/VACATION}' {} \; 

You should really look at Process Builder. It is really built for this kind of thing.

ProcessBuilder pb = new ProcessBuilder("myshellScript.sh", "myArg1", "myArg2");
 Map<String, String> env = pb.environment();
 env.put("VAR1", "myValue");
 env.remove("OTHERVAR");
 env.put("VAR2", env.get("VAR1") + "suffix");
 pb.directory(new File("myDir"));
 Process p = pb.start();

In Kotlin:

fun showListDialog(context: Context){
    // setup alert builder
    val builder = AlertDialog.Builder(context)
    builder.setTitle("Choose an Item")

    // add list items
    val listItems = arrayOf("Item 0","Item 1","Item 2")
    builder.setItems(listItems) { dialog, which ->
        when (which) {
            0 ->{
                Toast.makeText(context,"You Clicked Item 0",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
            1->{
                Toast.makeText(context,"You Clicked Item 1",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
            2->{
                Toast.makeText(context,"You Clicked Item 2",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
        }
    }

    // create & show alert dialog
    val dialog = builder.create()
    dialog.show()
}

redis-cli -h <host> -p <port> flushall

It will remove all data from client connected(with host and port)

mysql_* functions have been removed in PHP 7.

You probably have PHP 7 in XAMPP. You now have two alternatives: MySQLi and PDO.

Additionally, here is a nice wiki page about PDO.

A simple alternative is to use the new sessionStorage object. Per the comments, if you have 'continue where I left off' checked, sessionStorage will persist between restarts.

Delete it with git tag -d <tagname> and then recreate it on the correct commit.

The easiest way to get the correct number of hours between two dates (datetimes), even across daylight saving time changes, is to use the difference in Unix timestamps. Unix timestamps are seconds elapsed since 1970-01-01T00:00:00 UTC, ignoring leap seconds (this is OK because you probably don't need this precision, and because it's quite difficult to take leap seconds into account).

The most flexible way to convert a datetime string with optional timezone information into a Unix timestamp is to construct a DateTime object (optionally with a DateTimeZone as a second argument in the constructor), and then call its getTimestamp method.

$str1 = '2006-04-12 12:30:00'; 
$str2 = '2006-04-14 11:30:00';
$tz1 = new DateTimeZone('Pacific/Apia');
$tz2 = $tz1;
$d1 = new DateTime($str1, $tz1); // tz is optional,
$d2 = new DateTime($str2, $tz2); // and ignored if str contains tz offset
$delta_h = ($d2->getTimestamp() - $d1->getTimestamp()) / 3600;
if ($rounded_result) {
   $delta_h = round ($delta_h);
} else if ($truncated_result) {
   $delta_h = intval($delta_h);
}
echo "?h: $delta_h\n";

In a REST API, you shouldn't be overly concerned by predictable URI's. The very suggestion of URI predictability alludes to a misunderstanding of RESTful architecture. It assumes that a client should be constructing URIs themselves, which they really shouldn't have to.

However, I assume that you are not creating a true REST API, but a 'REST inspired' API (such as the Google Drive one). In these cases the rule of thumb is 'path params = resource identification' and 'query params = resource sorting'. So, the question becomes, can you uniquely identify your resource WITHOUT status / region? If yes, then perhaps its a query param. If no, then its a path param.

HTH.

Actually one detail is missing from the answer that is selected as accepted (from Phil Ross)....

it DOES work in Chrome, and the solution is really silly!!

Both the parent and the element onto which you want to control page-breaking must be declared as:

position: relative

check out this fiddle: http://jsfiddle.net/petersphilo/QCvA5/5/show/

This is true for:

page-break-before
page-break-after
page-break-inside

However, controlling page-break-inside in Safari does not work (in 5.1.7, at least)

i hope this helps!!!

PS: The question below brought up that fact that recent versions of Chrome no longer respect this, even with the position: relative; trick. However, they do seem to respect:

-webkit-region-break-inside: avoid;

see this fiddle: http://jsfiddle.net/petersphilo/QCvA5/23/show

so i guess we have to add that now...

Hope this helps!

The other answers are excellent and I just want to provide a straight forward answer to this. Just limiting to jQuery asynchronous calls

All ajax calls (including the $.get or $.post or $.ajax) are asynchronous.

Considering your example

var outerScopeVar;  //line 1
$.post('loldog', function(response) {  //line 2
    outerScopeVar = response;
});
alert(outerScopeVar);  //line 3

The code execution starts from line 1, declares the variable and triggers and asynchronous call on line 2, (i.e., the post request) and it continues its execution from line 3, without waiting for the post request to complete its execution.

Lets say that the post request takes 10 seconds to complete, the value of outerScopeVar will only be set after those 10 seconds.

To try out,

var outerScopeVar; //line 1
$.post('loldog', function(response) {  //line 2, takes 10 seconds to complete
    outerScopeVar = response;
});
alert("Lets wait for some time here! Waiting is fun");  //line 3
alert(outerScopeVar);  //line 4

Now when you execute this, you would get an alert on line 3. Now wait for some time until you are sure the post request has returned some value. Then when you click OK, on the alert box, next alert would print the expected value, because you waited for it.

In real life scenario, the code becomes,

var outerScopeVar;
$.post('loldog', function(response) {
    outerScopeVar = response;
    alert(outerScopeVar);
});

All the code that depends on the asynchronous calls, is moved inside the asynchronous block, or by waiting on the asynchronous calls.

SELECT 
   AcId, AcName, PldepPer, RepId, CustCatg, HardCode, BlockCust, CrPeriod, CrLimit, 
   BillLimit, Mode, PNotes, gtab82.memno 
FROM
   VCustomer AS v1
INNER JOIN   
   gtab82 ON gtab82.memacid = v1.AcId 
WHERE (AcGrCode = '204' OR CreDebt = 'True') 
AND Masked = 'false'
ORDER BY AcName

You typically only use an alias for a table name when you need to prefix a column with the table name due to duplicate column names in the joined tables and the table name is long or when the table is joined to itself. In your case you use an alias for VCustomer but only use it in the ON clause for uncertain reasons. You may want to review that aspect of your code.

Here's the code I built for that. There's no parsing of the contents, just plain conversion.

from xml.dom import minidom
import simplejson as json
def parse_element(element):
    dict_data = dict()
    if element.nodeType == element.TEXT_NODE:
        dict_data['data'] = element.data
    if element.nodeType not in [element.TEXT_NODE, element.DOCUMENT_NODE, 
                                element.DOCUMENT_TYPE_NODE]:
        for item in element.attributes.items():
            dict_data[item[0]] = item[1]
    if element.nodeType not in [element.TEXT_NODE, element.DOCUMENT_TYPE_NODE]:
        for child in element.childNodes:
            child_name, child_dict = parse_element(child)
            if child_name in dict_data:
                try:
                    dict_data[child_name].append(child_dict)
                except AttributeError:
                    dict_data[child_name] = [dict_data[child_name], child_dict]
            else:
                dict_data[child_name] = child_dict 
    return element.nodeName, dict_data

if __name__ == '__main__':
    dom = minidom.parse('data.xml')
    f = open('data.json', 'w')
    f.write(json.dumps(parse_element(dom), sort_keys=True, indent=4))
    f.close()

From a little reading, it appears that under the hood the String.Contains method simply calls String.IndexOf. The difference is String.Contains returns a boolean while String.IndexOf returns an integer with (-1) representing that the substring was not found.

I would suggest writing a little test with 100,000 or so iterations and see for yourself. If I were to guess, I'd say that IndexOf may be slightly faster but like I said it just a guess.

Jeff Atwood has a good article on strings at his blog. It's more about concatenation but may be helpful nonetheless.

make Sublime Text 3 your default text editor: (Restart required)

defaults write com.apple.LaunchServices LSHandlers -array-add "{LSHandlerContentType=public.plain-text;LSHandlerRoleAll=com.sublimetext.3;}"

make sublime then your default git text editor git config --global core.editor "subl -W"

I was ultimately able to resolve the solution by setting the column type in the flat file connection to be of type "database date [DT_DBDATE]"

Apparently the differences between these date formats are as follow:

DT_DATE A date structure that consists of year, month, day, and hour.

DT_DBDATE A date structure that consists of year, month, and day.

DT_DBTIMESTAMP A timestamp structure that consists of year, month, hour, minute, second, and fraction

By changing the column type to DT_DBDATE the issue was resolved - I attached a Data Viewer and the CYCLE_DATE value was now simply "12/20/2010" without a time component, which apparently resolved the issue.

It might help you!

AngularJs Code-sample

var app = angular.module('urlApp', []);
app.controller('urlCtrl', function ($scope, $log, $window) {
    $scope.ClickMeToRedirect = function () {
        var url = "http://" + $window.location.host + "/Account/Login";
        $log.log(url);
        $window.location.href = url;
    };
});

HTML Code-sample

<div ng-app="urlApp">
    <div ng-controller="urlCtrl">
        Redirect to <a href="#" ng-click="ClickMeToRedirect()">Click Me!</a>
    </div>
</div>

I have used similar code for downloading logs from servers. I debug my code and discovered that implementation of URLConnection which is returned is sun.net.www.protocol.http.HttpURLConnection.

Abstract class java.net.URLConnection have two attributes connectTimeout and readTimeout and setters are in abstract class. Believe or not implementation sun.net.www.protocol.http.HttpURLConnection have same attributes connectTimeout and readTimeout without setters and attributes from implementation class are used in getInputStream method. So there is no use of setting connectTimeout and readTimeout because they are never used in getInputStream method. In my opinion this is bug in sun.net.www.protocol.http.HttpURLConnection implementation.

My solution for this was to use HttpClient and Get request.

Many others have done an excellent job here giving a basic answer, especially Tobias Mühl. As mentioned, GMail's Api very closely matches the definition given by RFC2368 and RFC6068. This is true of the extended form of the mailto: links, but it's also true in the commonly-used forms found in the other answers. Of the five parameters, four are identical (such as to, cc, bcc and body) and one received only slight modification (su is gmail's version of subject).

If you want to know more about what you can do with mailTo gmail URLs, then these RFCs might be of help. Unfortunately, Google has not published any source themselves.

To clarify the parameters:

• to - Email to who
• su (gmail API) / subject (mailTo API) - Email Title
• body - Email Body
• bcc - Email Blind-Carbon Copy
• cc - Email Carbon Copy address

I see that you tagged this with Ubuntu. Most likely the MySQL driver (and possibly MySQL) is not installed. Assuming you have SSH or terminal access and sudo permissions, log into the server and run this:

sudo apt-get install mysql-server mysql-client php5-mysql

If the MySQL packages or the php5-mysql package are already installed, this will update them.

UPDATE

Since this answer still gets the occasional click I am going to update it to include PHP 7. PHP 7 requires a different package for MySQL so you will want to use a different argument for the apt-get command.

# Replace 7.4 with your version of PHP
sudo apt-get install mysql-server mysql-common php7.4 php7.4-mysql

And importantly, mysql_connect() has been deprecated since PHP v5.5.0. Refer the official documentation here: PHP: mysql_connect()

You could use the nuget package Newtonsoft.JSON in order to achieve this:

JsonConvert.DeserializeObject<List<Response>>(yourJsonString)

How did you try it? Maybe you are working with \ and omit proper escaping.

Instead of

open('\\HOST\share\path\to\file')

use either Johnsyweb's solution with the /s, or try one of

open(r'\\HOST\share\path\to\file')

or

open('\\\\HOST\\share\\path\\to\\file')

.

Update March 2015

Python 2.7.9 and later (on the Python 2 series), and Python 3.4 and later include pip by default, so you may have pip already.

If you don't, run this one line command on your prompt (which may require administrator access):

python -c "exec('try: from urllib2 import urlopen \nexcept: from urllib.request import urlopen');f=urlopen('https://bootstrap.pypa.io/get-pip.py').read();exec(f)"

It will install pip. If Setuptools is not already installed, get-pip.py will install it for you too.

As mentioned in comments, the above command will download code from the Pip source code repository at GitHub, and dynamically run it at your environment. So be noticed that this is a shortcut of the steps download, inspect and run, all with a single command using Python itself. If you trust Pip, proceed without doubt.

Be sure that your Windows environment variable PATH includes Python's folders (for Python 2.7.x default install: C:\Python27 and C:\Python27\Scripts, for Python 3.3x: C:\Python33 and C:\Python33\Scripts, and so on).

First, have program 1 write the string to stdout (as if you'd like it to appear in screen). Then the second program should read a string from stdin, as if a user was typing from a keyboard. then you run:

$ program_1 | program_2

Note: This example uses the draft version of the Flexible Box Layout Module. It has been superseded by the incompatible modern specification.

Center the child elements of a div box by using the box-align and box-pack properties together.

Example:

div
{
width:350px;
height:100px;
border:1px solid black;

/* Internet Explorer 10 */
display:-ms-flexbox;
-ms-flex-pack:center;
-ms-flex-align:center;

/* Firefox */
display:-moz-box;
-moz-box-pack:center;
-moz-box-align:center;

/* Safari, Opera, and Chrome */
display:-webkit-box;
-webkit-box-pack:center;
-webkit-box-align:center;

/* W3C */
display:box;
box-pack:center;
box-align:center;
} 

I struggled with the same problem. I wanted to have the default value from the database into the entities (automatically). Guess what, I did it :)

You can easily create your own extension method on IEnumerable or IQueryable:

public static IOrderedEnumerable<TSource> OrderByWithDirection<TSource,TKey>
    (this IEnumerable<TSource> source,
     Func<TSource, TKey> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

public static IOrderedQueryable<TSource> OrderByWithDirection<TSource,TKey>
    (this IQueryable<TSource> source,
     Expression<Func<TSource, TKey>> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

Yes, you lose the ability to use a query expression here - but frankly I don't think you're actually benefiting from a query expression anyway in this case. Query expressions are great for complex things, but if you're only doing a single operation it's simpler to just put that one operation:

var query = dataList.OrderByWithDirection(x => x.Property, direction);

You have to check on this.

HTML

<button id="saveActionId"> Save </button>

manifest.json

  "permissions": [
    "activeTab",
    "tabs"
   ]

JavaScript
The below code will save all the urls of active window into JSON object as part of button click.

var saveActionButton = document.getElementById('saveActionId');
saveActionButton.addEventListener('click', function() {
    myArray = [];
    chrome.tabs.query({"currentWindow": true},  //{"windowId": targetWindow.id, "index": tabPosition});
    function (array_of_Tabs) {  //Tab tab
        arrayLength = array_of_Tabs.length;
        //alert(arrayLength);
        for (var i = 0; i < arrayLength; i++) {
            myArray.push(array_of_Tabs[i].url);
        }
        obj = JSON.parse(JSON.stringify(myArray));
    });
}, false);

I would add for Debian you need at least one compiler in the system (according to Debian Stretch and Jessie 32-bit libraries ).

I installed apt-get install -y gcc-multilib in order to run 32-bit executable file in my docker container based on debian:jessie.

As long as you override equals() on each key and value contained in the map, then m1.equals(m2) should be reliable to check for maps equality.

The same result can be obtained also by comparing toString() of each map as you suggested, but using equals() is a more intuitive approach.

May not be your specific situation, but if you store arrays in the map, may be a little tricky, because they must be compared value by value, or using Arrays.equals(). More details about this see here.

The guys have given the simple solution, which will do be you should have a look at the help - it's good, looks like a lot in one go but it's actually quick to read:

<label for="my_checkbox">Check me</label>
<input type="checkbox" name="my_checkbox" value="Car" />

I found the Glide as better option than Picasso. I was using picasso to load around 32 images of size around 200-500KB each and I was always getting OOM. But the Glide solved my all OOM issues.

To check if a particular key in the map exists, use the count member function in one of the following ways:

m.count(key) > 0
m.count(key) == 1
m.count(key) != 0

The documentation for map::find says: "Another member function, map::count, can be used to just check whether a particular key exists."

The documentation for map::count says: "Because all elements in a map container are unique, the function can only return 1 (if the element is found) or zero (otherwise)."

To retrieve a value from the map via a key that you know to exist, use map::at:

value = m.at(key)

Unlike map::operator[], map::at will not create a new key in the map if the specified key does not exist.

You can make use of regex's quantifier feature since lookaround may not be supported all the time.

(\bjames\b){1,}.*(\bjack\b){1,}|(\bjack\b){1,}.*(\bjames\b){1,}

If you know that the switch statement will only ever have a strict defined set of labels or values, just do this to cover the bases, that way you will always get valid outcome.. Just put the default over the label that would programmatically/logically be the best handler for other values.

switch(ResponseValue)
{
    default:
    case No:
        return false;
    case Yes;
        return true;
}

Official solution

Add those two code snippets to your SubActivity

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getActionBar().setDisplayHomeAsUpEnabled(true);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    // Respond to the action bar's Up/Home button
    case android.R.id.home:
        NavUtils.navigateUpFromSameTask(this);
        return true;
    }
    return super.onOptionsItemSelected(item);
}

add meta-data and parentActivity to manifest to support lower sdk.

 <application ... >
    ...
    <!-- The main/home activity (it has no parent activity) -->
    <activity
        android:name="com.example.myfirstapp.MainActivity" ...>
        ...
    </activity>
    <!-- A child of the main activity -->
    <activity
        android:name="com.example.myfirstapp.SubActivity"
        android:label="@string/title_activity_display_message"
        android:parentActivityName="com.example.myfirstapp.MainActivity" >
        <!-- Parent activity meta-data to support 4.0 and lower -->
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.myfirstapp.MainActivity" />

I'm not sure what was wrong with The MYYN's answer.

if (yourString != null) {
  //do fun stuff with yourString here
}

The above null check is quite alright.

If you are trying to check if a String reference is equal (ignoring case) to another string that you know is not a null reference, then do something like this:

String x = "this is not a null reference"
if (x.equalsIgnoreCase(yourStringReferenceThatMightBeNull) ) {
  //do fun stuff
}

If there is any doubt as to whether or not you have null references for both Strings you are comparing, you'll need to check for a null reference on at least one of them to avoid the possibility of a NullPointerException.

As simple as it can be

Use $(this) here too

$(document).on("click",".appDetails", function () {
   var clickedBtnID = $(this).attr('id'); // or var clickedBtnID = this.id
   alert('you clicked on button #' + clickedBtnID);
});

I know this is not a coding answer but it is what the OP wanted and what I have spent half the day trying to achieve - print from a web page with page numbers.

• Print to pdf without the numbers
• Run it through ilovepdf here https://www.ilovepdf.com/add_pdf_page_number which adds the page numbers

Yes, it is two steps instead of one but I haven't been able to find any CSS option despite several hours of searching. Real shame all the browsers removed the functionality that used to allow it.

Having sequential ID's makes it a LOT easier for a hacker or data miner to compromise your site and data. Keep that in mind when choosing a PK for a website.

In the root of your project create your environment files:

• .env
• .env.someEnvironment1
• .env.SomeEnvironment2

To then load those configs, you would specify the environment via mode i.e.

npm run serve --mode development //default mode
npm run serve --mode someEnvironment1

In your env files you simply declare the config as key-value pairs, but if you're using vue 3, you must prefix with VUE_APP_:

In your .env:

VUE_APP_TITLE=This will get overwritten if more specific available

.env.someEnvironment1:

VUE_APP_TITLE=My App (someEnvironment1)

You can then use this in any of your components via:

myComponent.vue:

<template>
  <div> 
    {{title}}
  </div>
</template>

<script>
export default {
  name: "MyComponent",
  data() {
    return {
      title: process.env.VUE_APP_TITLE
    };
  }
};
</script>

Now if you ran the app without a mode it will show the 'This will get...' but if you specify a someEnvironment1 as your mode then you will get the title from there.

You can create configs that are 'hidden' from git by appending .local to your file: .env.someEnvironment1.local - very useful for when you have secrets.

If you are using the vs code for editing then try restarting the editor.This scenario fixed my issue.I think it's the issue with editor cache.

A full answer: (Tested with r71)

To set a background color use:

renderer.setClearColor( 0xffffff ); // white background - replace ffffff with any hex color

If you want a transparent background you will have to enable alpha in your renderer first:

renderer = new THREE.WebGLRenderer( { alpha: true } ); // init like this
renderer.setClearColor( 0xffffff, 0 ); // second param is opacity, 0 => transparent

Find the total size of both array and set array1and2 to the total size of both array added. Then loop array1 and then array2 and add the values into array1and2.

Emulation is a multi-faceted area. Here are the basic ideas and functional components. I'm going to break it into pieces and then fill in the details via edits. Many of the things I'm going to describe will require knowledge of the inner workings of processors -- assembly knowledge is necessary. If I'm a bit too vague on certain things, please ask questions so I can continue to improve this answer.

Basic idea:

Emulation works by handling the behavior of the processor and the individual components. You build each individual piece of the system and then connect the pieces much like wires do in hardware.

Processor emulation:

There are three ways of handling processor emulation:

• Interpretation
• Dynamic recompilation
• Static recompilation

With all of these paths, you have the same overall goal: execute a piece of code to modify processor state and interact with 'hardware'. Processor state is a conglomeration of the processor registers, interrupt handlers, etc for a given processor target. For the 6502, you'd have a number of 8-bit integers representing registers: A, X, Y, P, and S; you'd also have a 16-bit PC register.

With interpretation, you start at the IP (instruction pointer -- also called PC, program counter) and read the instruction from memory. Your code parses this instruction and uses this information to alter processor state as specified by your processor. The core problem with interpretation is that it's very slow; each time you handle a given instruction, you have to decode it and perform the requisite operation.

With dynamic recompilation, you iterate over the code much like interpretation, but instead of just executing opcodes, you build up a list of operations. Once you reach a branch instruction, you compile this list of operations to machine code for your host platform, then you cache this compiled code and execute it. Then when you hit a given instruction group again, you only have to execute the code from the cache. (BTW, most people don't actually make a list of instructions but compile them to machine code on the fly -- this makes it more difficult to optimize, but that's out of the scope of this answer, unless enough people are interested)

With static recompilation, you do the same as in dynamic recompilation, but you follow branches. You end up building a chunk of code that represents all of the code in the program, which can then be executed with no further interference. This would be a great mechanism if it weren't for the following problems:

• Code that isn't in the program to begin with (e.g. compressed, encrypted, generated/modified at runtime, etc) won't be recompiled, so it won't run
• It's been proven that finding all the code in a given binary is equivalent to the Halting problem

These combine to make static recompilation completely infeasible in 99% of cases. For more information, Michael Steil has done some great research into static recompilation -- the best I've seen.

The other side to processor emulation is the way in which you interact with hardware. This really has two sides:

• Processor timing
• Interrupt handling

Processor timing:

Certain platforms -- especially older consoles like the NES, SNES, etc -- require your emulator to have strict timing to be completely compatible. With the NES, you have the PPU (pixel processing unit) which requires that the CPU put pixels into its memory at precise moments. If you use interpretation, you can easily count cycles and emulate proper timing; with dynamic/static recompilation, things are a /lot/ more complex.

Interrupt handling:

Interrupts are the primary mechanism that the CPU communicates with hardware. Generally, your hardware components will tell the CPU what interrupts it cares about. This is pretty straightforward -- when your code throws a given interrupt, you look at the interrupt handler table and call the proper callback.

Hardware emulation:

There are two sides to emulating a given hardware device:

• Emulating the functionality of the device
• Emulating the actual device interfaces

Take the case of a hard-drive. The functionality is emulated by creating the backing storage, read/write/format routines, etc. This part is generally very straightforward.

The actual interface of the device is a bit more complex. This is generally some combination of memory mapped registers (e.g. parts of memory that the device watches for changes to do signaling) and interrupts. For a hard-drive, you may have a memory mapped area where you place read commands, writes, etc, then read this data back.

I'd go into more detail, but there are a million ways you can go with it. If you have any specific questions here, feel free to ask and I'll add the info.

Resources:

I think I've given a pretty good intro here, but there are a ton of additional areas. I'm more than happy to help with any questions; I've been very vague in most of this simply due to the immense complexity.

Obligatory Wikipedia links:

• Emulator
• Dynamic recompilation

General emulation resources:

• Zophar -- This is where I got my start with emulation, first downloading emulators and eventually plundering their immense archives of documentation. This is the absolute best resource you can possibly have.
• NGEmu -- Not many direct resources, but their forums are unbeatable.
• RomHacking.net -- The documents section contains resources regarding machine architecture for popular consoles

Emulator projects to reference:

• IronBabel -- This is an emulation platform for .NET, written in Nemerle and recompiles code to C# on the fly. Disclaimer: This is my project, so pardon the shameless plug.
• BSnes -- An awesome SNES emulator with the goal of cycle-perfect accuracy.
• MAME -- The arcade emulator. Great reference.
• 6502asm.com -- This is a JavaScript 6502 emulator with a cool little forum.
• dynarec'd 6502asm -- This is a little hack I did over a day or two. I took the existing emulator from 6502asm.com and changed it to dynamically recompile the code to JavaScript for massive speed increases.

Processor recompilation references:

• The research into static recompilation done by Michael Steil (referenced above) culminated in this paper and you can find source and such here.

Addendum:

It's been well over a year since this answer was submitted and with all the attention it's been getting, I figured it's time to update some things.

Perhaps the most exciting thing in emulation right now is libcpu, started by the aforementioned Michael Steil. It's a library intended to support a large number of CPU cores, which use LLVM for recompilation (static and dynamic!). It's got huge potential, and I think it'll do great things for emulation.

emu-docs has also been brought to my attention, which houses a great repository of system documentation, which is very useful for emulation purposes. I haven't spent much time there, but it looks like they have a lot of great resources.

I'm glad this post has been helpful, and I'm hoping I can get off my arse and finish up my book on the subject by the end of the year/early next year.

@EnableWebMvc annotation on config class resolved my problem. (Spring 5, no web.xml, initialized by AbstractAnnotationConfigDispatcherServletInitializer)

It could be PowerShell's default security level, which (IIRC) will only run signed scripts.

Try typing this:

set-executionpolicy remotesigned

That will tell PowerShell to allow local (that is, on a local drive) unsigned scripts to run.

Then try executing your script again.

You can use:

input[type=text]
{
 /*Styles*/
}

Define your common style attributes inside this. and for extra style you can add a class then.

You can also do just:

$k = array_rand($array);
$v = $array[$k];

This is the way to do it when you have an associative array.

You should take a look at Batarang for AngularJS debugging

As for your issue:

Your scope variable is not directly attached to the modal correctly. Below is the adjusted code. You need to specify when the modal shows using ng-show

<!-- Confirmation Dialog -->
<div class="modal" modal="showModal" ng-show="showModal">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h4 class="modal-title">Delete confirmation</h4>
      </div>
      <div class="modal-body">
        <p>Are you sure?</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal" ng-click="cancel()">No</button>
        <button type="button" class="btn btn-primary" ng-click="ok()">Yes</button>
      </div>
    </div>
  </div>
</div>

I achieved the same thing using a local web server and PHP. I used a script containing shell_exec to launch an application locally.

Alternatively, you could do something like this:

<a href="file://C:/Windows/notepad.exe">Notepad</a>

Arrays.asList can help here:

new ArrayList<Integer>(Arrays.asList(1,2,3,5,8,13,21));

It is varchar and not var_char

CREATE DATABASE IF NOT EXISTS courses;

USE courses;

CREATE TABLE IF NOT EXISTS teachers(
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL,
    addr VARCHAR(255) NOT NULL,
    phone INT NOT NULL
);

You should use a SQL tool to visualize possbile errors like MySQL Workbench.

For example if I had an application source code structure that looked like this:

• C:\b2b\com\steve\util\
• C:\b2b\com\steve\app\
• C:\b2b\com\steve\gui\

Then I would do:

javadoc -d "C:\docs" -sourcepath "C:\b2b" -subpackages com

And that should create javadocs for source code of the com package, and all subpackages (recursively), found inside the "C:\b2b" directory.

BIRT works pretty well.

From wikipedia:

A Postback is an action taken by an interactive webpage, when the entire page and its contents are sent to the server for processing some information and then, the server posts the same page back to the browser.

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

You haven't provided your javascript code, but the usual cause of this type of issue is not waiting till the page is loaded. Remember that most javascript is executed before the DOM is loaded, so code trying to manipulate it won't work.

To run code after the page has finished loading, use the $(document).ready callback:

$(document).ready(function(){
  $('#some-id').trigger('click');
});

Let's assume we have an array of objects and you want to check if value of name is defined like this,

let persons = [ {"name" : "test1"},{"name": "test2"}];

if(persons.some(person => person.name == 'test1')) {
    ... here your code in case person.name is defined and available
}

For people still getting the issue.

I face same problem and seems some .jar file missing.

so try tar -xf apache-jmeter-5.2.1.tgz in the console rather than just right click unzip. And also, try binary package if source package still has an issue. this solve my issue (I am using ubuntu)

Here is a fast and highly readable way to get the min date value

Note: This is a Deterministic Function, so to improve performance further we might as well apply WITH SCHEMABINDING to the return value.

Create a function

CREATE FUNCTION MinDate()
RETURNS DATETIME WITH SCHEMABINDING
AS
BEGIN
    RETURN CONVERT(DATETIME, -53690)

END

Call the function

dbo.MinDate()

Example 1

PRINT dbo.MinDate()

Example 2

PRINT 'The minimimum date allowed in an SQL database is ' + CONVERT(VARCHAR(MAX), dbo.MinDate())

Example 3

SELECT * FROM Table WHERE DateValue > dbo.MinDate()

Example 4

SELECT dbo.MinDate() AS MinDate

Example 5

DECLARE @MinDate AS DATETIME = dbo.MinDate()

SELECT @MinDate AS MinDate

For me it was simple as running:

/usr/local/opt/mysql/bin/mysqld_safe

instead of mysqld

Under Windows only: You may try to use ini_set() function^Docs for the SMTP^Docs and smtp_port^Docs settings:

ini_set('SMTP', 'mysmtphost'); 
ini_set('smtp_port', 25); 

Thanks for all your help! @Svetoslav Tsolov had it very close, but I was still getting an error, until I figured out the closing parenthesis was in the wrong place. Here's the final query that works:

SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID, 
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
(CASE WHEN dbo.EU_Admin3.EUID IS NULL THEN dbo.EU_Admin2.EUID ELSE dbo.EU_Admin3.EUID END) AS EUID
FROM dbo.AdminID 

LEFT OUTER JOIN dbo.EU_Admin2
ON dbo.AdminID.DistrictID = dbo.EU_Admin2.DistrictID

LEFT OUTER JOIN dbo.EU_Admin3
ON dbo.AdminID.ADMIN3_ID = dbo.EU_Admin3.ADMIN3_ID

Use .prop() instead and if we go with your code then compare like this:

Look at the example jsbin:

  $("#news_list tr").click(function () {
    var ele = $(this).find(':checkbox');
    if ($(':checked').length) {
      ele.prop('checked', false);
      $(this).removeClass('admin_checked');
    } else {
      ele.prop('checked', true);
      $(this).addClass('admin_checked');
    }
 });

Changes:

1. Changed input to :checkbox.
2. Comparing the length of the checked checkboxes.

1. File >In androidStudio Open your application(your project)

2. Go to res folder and then right click on that folder select the new tab in that go to image asset tab you will get asset studio display page .

3. Browse(select) the icon that you want get as app icon(no need to change the drawble folder) .

4. And then click next tab and finish.

5. your new icon will displayed in the app.

printStackTrace() helps the programmer to understand where the actual problem occurred. It helps to trace the exception. it is printStackTrace() method of Throwable class inherited by every exception class. This method prints the same message of e object and also the line number where the exception occurred.

The following is an another example of print stack of the Exception in Java.

public class Demo {
   public static void main(String[] args) {
      try {
         ExceptionFunc();
      } catch(Throwable e) {
         e.printStackTrace();
      }
   }
   public static void ExceptionFunc() throws Throwable {
      Throwable t = new Throwable("This is new Exception in Java...");

      StackTraceElement[] trace = new StackTraceElement[] {
         new StackTraceElement("ClassName","methodName","fileName",5)
      };
      t.setStackTrace(trace);
      throw t;
   }
}

java.lang.Throwable: This is new Exception in Java... at ClassName.methodName(fileName:5)

I just want to add one example of the kind of unchecked warning I see quite often. If you use classes that implement an interface like Serializable, often you will call methods that return objects of the interface, and not the actual class. If the class being returned must be cast to a type based on generics, you can get this warning.

Here is a brief (and somewhat silly) example to demonstrate:

import java.io.Serializable;

public class SimpleGenericClass<T> implements Serializable {

    public Serializable getInstance() {
        return this;
    }

    // @SuppressWarnings("unchecked")
    public static void main() {

        SimpleGenericClass<String> original = new SimpleGenericClass<String>();

        //  java: unchecked cast
        //    required: SimpleGenericClass<java.lang.String>
        //    found:    java.io.Serializable
        SimpleGenericClass<String> returned =
                (SimpleGenericClass<String>) original.getInstance();
    }
}

getInstance() returns an object that implements Serializable. This must be cast to the actual type, but this is an unchecked cast.

After perusing your previous questions I eventually determined you are probably on SQL Server 2005. For US format you would use style 101

select Subject, 
       CONVERT(varchar,DeliveryDate,101) as DeliveryDate
from Email_Administration 
where MerchantId =@MerchantID 

If you don't want to place the watch inside a specific controller, you can add the watch for the whole aplication in Angular app run()

var myApp = angular.module('myApp', []);

myApp.run(function($rootScope) {
    $rootScope.$on("$locationChangeStart", function(event, next, current) { 
        // handle route changes     
    });
});

Even if it looks like the module is installed, as far as Python is concerned it isn't since it throws that exception.

Try installing the module again using one of the installation methods shown in the XlsxWriter docs and look out for any installation errors.

If there are none then run a sample program like the following:

import xlsxwriter

workbook = xlsxwriter.Workbook('hello.xlsx')
worksheet = workbook.add_worksheet()

worksheet.write('A1', 'Hello world')

workbook.close()

This works on Android Studio 1.x:

• Tools --> Android --> Android Device Monitor (this open the ADM)
• Window --> Show View
• Search for File Explorer then press the OK Button
• The File Explorer Tab is now open on the View

If you are insisting to use the window.location.origin You can put this in top of your code before reading the origin

if (!window.location.origin) {
  window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
}

Please use Spring Tool Suite (Eclipse-based development environment that is customized for developing Spring applications).
Create a Spring Starter Project, it will create the directory structure for you with the spring boot maven dependencies.

This is the code you need

I have modified the top liked code to indent in a jupyter notebook python 3 correctly

import numpy as np
from sklearn.tree import _tree

def tree_to_code(tree, feature_names):
    tree_ = tree.tree_
    feature_name = [feature_names[i] 
                    if i != _tree.TREE_UNDEFINED else "undefined!" 
                    for i in tree_.feature]
    print("def tree({}):".format(", ".join(feature_names)))

    def recurse(node, depth):
        indent = "    " * depth
        if tree_.feature[node] != _tree.TREE_UNDEFINED:
            name = feature_name[node]
            threshold = tree_.threshold[node]
            print("{}if {} <= {}:".format(indent, name, threshold))
            recurse(tree_.children_left[node], depth + 1)
            print("{}else:  # if {} > {}".format(indent, name, threshold))
            recurse(tree_.children_right[node], depth + 1)
        else:
            print("{}return {}".format(indent, np.argmax(tree_.value[node])))

    recurse(0, 1)

Alternatively to a redirect, if it is calling your own code, you could use this:

actionContext.Result = new RedirectToRouteResult(
    new RouteValueDictionary(new { controller = "Home", action = "Error" })
);

actionContext.Result.ExecuteResult(actionContext.Controller.ControllerContext);

It is not a pure redirect but gives a similar result without unnecessary overhead.

Detect the browser and use Data-URI for Chrome and use PDF.js as below for other browsers.

PDFJS.getDocument(url_of_pdf)
.then(function(pdf) {
    return pdf.getPage(1);
})
.then(function(page) {
    // get a viewport
    var scale = 1.5;
    var viewport = page.getViewport(scale);
    // get or create a canvas
    var canvas = ...;
    canvas.width = viewport.width;
    canvas.height = viewport.height;

    // render a page
    page.render({
        canvasContext: canvas.getContext('2d'),
        viewport: viewport
    });
})
.catch(function(err) {
    // deal with errors here!
});

listOfNames="db_one db_two db_three"
for databaseName in $listOfNames
do
  echo $databaseName
done

or just

for databaseName in db_one db_two db_three
do
  echo $databaseName
done

They are both going to have the same effect.

However, as pointed out in the comments: $(window).scrollTop() is supported by more web browsers than $('html').scrollTop().

I've had the same problem you describe. The web site I'm building can be accessed from a mobile phone and from the browser so I need an api to allow users to signup, login and do some specific tasks. Furthermore, I need to support scalability, the same code running on different processes/machines.

Because users can CREATE resources (aka POST/PUT actions) you need to secure your api. You can use oauth or you can build your own solution but keep in mind that all the solutions can be broken if the password it's really easy to discover. The basic idea is to authenticate users using the username, password and a token, aka the apitoken. This apitoken can be generated using node-uuid and the password can be hashed using pbkdf2

Then, you need to save the session somewhere. If you save it in memory in a plain object, if you kill the server and reboot it again the session will be destroyed. Also, this is not scalable. If you use haproxy to load balance between machines or if you simply use workers, this session state will be stored in a single process so if the same user is redirected to another process/machine it will need to authenticate again. Therefore you need to store the session in a common place. This is typically done using redis.

When the user is authenticated (username+password+apitoken) generate another token for the session, aka accesstoken. Again, with node-uuid. Send to the user the accesstoken and the userid. The userid (key) and the accesstoken (value) are stored in redis with and expire time, e.g. 1h.

Now, every time the user does any operation using the rest api it will need to send the userid and the accesstoken.

If you allow the users to signup using the rest api, you'll need to create an admin account with an admin apitoken and store them in the mobile app (encrypt username+password+apitoken) because new users won't have an apitoken when they sign up.

The web also uses this api but you don't need to use apitokens. You can use express with a redis store or use the same technique described above but bypassing the apitoken check and returning to the user the userid+accesstoken in a cookie.

If you have private areas compare the username with the allowed users when they authenticate. You can also apply roles to the users.

Summary:

An alternative without apitoken would be to use HTTPS and to send the username and password in the Authorization header and cache the username in redis.

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

I found the most simple approach by changing the default encoding of the whole script to be 'UTF-8':

import sys
reload(sys)
sys.setdefaultencoding('utf8')

any open, print or other statement will just use utf8.

Works at least for Python 2.7.9.

Thx goes to https://markhneedham.com/blog/2015/05/21/python-unicodeencodeerror-ascii-codec-cant-encode-character-uxfc-in-position-11-ordinal-not-in-range128/ (look at the end).

After trying out every solution I could find:

• Turning off strict ssl: npm config set strict-ssl=false
• Changing the registry to http instead of https: npm config set registry http://registry.npmjs.org/
• Changing my cafile setting: npm config set cafile /path/to/your/cert.pem
• Stop rejecting unknown CAs: set NODE_TLS_REJECT_UNAUTHORIZED=0

The solution that seems to be working the best for me now is to use the NODE_EXTRA_CA_CERTS environment variable which extends the existing CAs rather than replacing them with the cafile option in your .npmrc file. You can set it by entering this in your terminal: NODE_EXTRA_CA_CERTS=path/to/your/cert.pem

Of course, setting this variable every time can be annoying, so I added it to my bash profile so that it will be set every time I open terminal. If you don’t already have a ~/.bash_profile file, create one. Then at the end of that file add export NODE_EXTRA_CA_CERTS=path/to/your/cert.pem. Then, remove the cafile setting in your .npmrc.

You'll want a Map<String, String>. Classes that implement the Map interface include (but are not limited to):

• HashMap
• LinkedHashMap
• Hashtable

Each is designed/optimized for certain situations (go to their respective docs for more info). HashMap is probably the most common; the go-to default.

For example (using a HashMap):

Map<String, String> map = new HashMap<String, String>();
map.put("dog", "type of animal");
System.out.println(map.get("dog"));

type of animal

I solved this problem very easily after finding out this happens when you aren't outputting a proper JSON object, I simply used the echo json_encode($arrayName); instead of print_r($arrayName); With my php api.

Every programming language or at least most programming languages should have their own version of the json_encode() and json_decode() functions.

You should use the options 'year', 'month', and 'date' when initializing to specify the initial date value used by fullcalendar:

$('#calendar').fullCalendar({
 year: 2012,
 month: 4,
 date: 25
});  // This will initialize for May 25th, 2012.

See the function setYMD(date,y,m,d) in the fullcalendar.js file; note that the JavaScript setMonth, setDate, and setFullYear functions are used, so your month value needs to be 0-based (Jan is 0).

UPDATE: As others have noted in the comments, the correct way now (V3 as of writing this edit) is to initialize the defaultDate property to a value that is

anything the Moment constructor accepts, including an ISO8601 date string like "2014-02-01"

as it uses Moment.js. Documentation here.

Updated example:

$('#calendar').fullCalendar({
    defaultDate: "2012-05-25"
});  // This will initialize for May 25th, 2012.

AssemblyVersion pretty much stays internal to .NET, while AssemblyFileVersion is what Windows sees. If you go to the properties of an assembly sitting in a directory and switch to the version tab, the AssemblyFileVersion is what you'll see up top. If you sort files by version, this is what's used by Explorer.

The AssemblyInformationalVersion maps to the "Product Version" and is meant to be purely "human-used".

AssemblyVersion is certainly the most important, but I wouldn't skip AssemblyFileVersion, either. If you don't provide AssemblyInformationalVersion, the compiler adds it for you by stripping off the "revision" piece of your version number and leaving the major.minor.build.

I had this same problem in asp.net mvc, I fixed it by putting this method in my base api controller that all my api controllers inherit from:

    /// <summary>
    /// Get the session from HttpContext.Current, if that is null try to get it from the Request properties.
    /// </summary>
    /// <returns></returns>
    protected HttpContextWrapper GetHttpContextWrapper()
    {
      HttpContextWrapper httpContextWrapper = null;
      if (HttpContext.Current != null)
      {
        httpContextWrapper = new HttpContextWrapper(HttpContext.Current);
      }
      else if (Request.Properties.ContainsKey("MS_HttpContext"))
      {
        httpContextWrapper = (HttpContextWrapper)Request.Properties["MS_HttpContext"];
      }
      return httpContextWrapper;
    }

Then in your api call that you want to access the session you just do:

HttpContextWrapper httpContextWrapper = GetHttpContextWrapper();
var someVariableFromSession = httpContextWrapper.Session["SomeSessionValue"];

I also have this in my Global.asax.cs file like other people have posted, not sure if you still need it using the method above, but here it is just in case:

/// <summary>
/// The following method makes Session available.
/// </summary>
protected void Application_PostAuthorizeRequest()
{
  if (HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath.StartsWith("~/api"))
  {
    HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required);
  }
}

You could also just make a custom filter attribute that you can stick on your api calls that you need session, then you can use session in your api call like you normally would via HttpContext.Current.Session["SomeValue"]:

  /// <summary>
  /// Filter that gets session context from request if HttpContext.Current is null.
  /// </summary>
  public class RequireSessionAttribute : ActionFilterAttribute
  {
    /// <summary>
    /// Runs before action
    /// </summary>
    /// <param name="actionContext"></param>
    public override void OnActionExecuting(HttpActionContext actionContext)
    {
      if (HttpContext.Current == null)
      {
        if (actionContext.Request.Properties.ContainsKey("MS_HttpContext"))
        {
          HttpContext.Current = ((HttpContextWrapper)actionContext.Request.Properties["MS_HttpContext"]).ApplicationInstance.Context;
        }
      }
    }
  }

Hope this helps.

Try http://simplefocus.com/flowtype/. This is what I use for my sites, and it has worked perfectly.

In my case, I was presenting the rootViewController of an UINavigationController when I was supposed to present the UINavigationController itself.

This could be an answer to your question:

JSONArray msg1 = (JSONArray) json.get("source");
for(int i = 0; i < msg1.length(); i++){
  String name = msg1.getString("name");
  int age     = msg1.getInt("age");
}

As you run the container, a directory on your host is created and mounted into the container. You can find out what directory this is with

$ docker inspect --format "{{ .Volumes }}" <ID>
map[/export:/var/lib/docker/vfs/dir/<VOLUME ID...>]

If you want to mount a directory from your host inside your container, you have to use the -v parameter and specify the directory. In your case this would be:

docker run -v /export:/export data

SO you would use the hosts folder inside your container.

In my case, I just needed to install oracle 10g client on the server, becase there there was the 11g version.

Ps: I don't needed unistall nothing, I just install the 10g version and updated the tnsnames file (C:\oracle\product\10.2.0\client_1\NETWORK\ADMIN)

This worked for me:

    import re
    text = 'how are u? umberella u! u. U. U@ U# u '
    rex = re.compile(r'\bu\b', re.IGNORECASE)
    print(rex.sub('you', text))

It pre-compiles the regular expression and makes use of re.IGNORECASE so that we don't have to worry about case in our regular expression! BTW, I love the funky spelling of umbrella! :-)

You have 2 options:

• Install using homebrew

brew update to update homebrew packages

brew install jmeter to install jmeter

Read this blog to know how to map folders from standard jmeter to homebrew installed version.

• Install using standard version which I would advise you to do. Steps are:

  1. Install Last compatible JDK version (7 or 8 as of JMeter 3.1).

  2. Download JMeter from here

  3. Unzip folder and run from the folder:

bin/jmeter

C++11 standard on jumping over some initializations

JohannesD gave an explanation, now for the standards.

The C++11 N3337 standard draft 6.7 "Declaration statement" says:

3 It is possible to transfer into a block, but not in a way that bypasses declarations with initialization. A program that jumps (87) from a point where a variable with automatic storage duration is not in scope to a point where it is in scope is ill-formed unless the variable has scalar type, class type with a trivial default constructor and a trivial destructor, a cv-qualified version of one of these types, or an array of one of the preceding types and is declared without an initializer (8.5).

87) The transfer from the condition of a switch statement to a case label is considered a jump in this respect.

[ Example:

void f() {
   // ...
  goto lx;    // ill-formed: jump into scope of a
  // ...
ly:
  X a = 1;
  // ...
lx:
  goto ly;    // OK, jump implies destructor
              // call for a followed by construction
              // again immediately following label ly
}

— end example ]

As of GCC 5.2, the error message now says:

crosses initialization of

C

C allows it: c99 goto past initialization

The C99 N1256 standard draft Annex I "Common warnings" says:

2 A block with initialization of an object that has automatic storage duration is jumped into

Most people already tried to answer your questions.
If you are still debugging, have you thought about using:

Double.TryParse(String, Double);

This will help you in determining what is wrong in each of the string first before you do the actual parsing.
If you have a culture-related problem, you might consider using:

Double.TryParse(String, NumberStyles, IFormatProvider, Double);

This http://msdn.microsoft.com/en-us/library/system.double.tryparse.aspx has a really good example on how to use them.

If you need a long, Int64.TryParse is also available: http://msdn.microsoft.com/en-us/library/system.int64.tryparse.aspx

Hope that helps.

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

npm uninstall yarn removes the yarn packages that are installed via npm but what yarn does underneath the hood is, it installs a software named yarn in your PC. If you have installed in Windows, Go to add or remove programs and then search for yarn and uninstall it then you are good to go.

No code change required:

While you are in debug mode within the catch {...} block open up the "QuickWatch" window (Ctrl+Alt+Q) and paste in there:

((System.Data.Entity.Validation.DbEntityValidationException)ex).EntityValidationErrors

or:

((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors

If you are not in a try/catch or don't have access to the exception object.

This will allow you to drill down into the ValidationErrors tree. It's the easiest way I've found to get instant insight into these errors.

Actually, ECMAScript says on page 15: That an identifier may start with a $, an underscore or a UnicodeLetter, and then it goes on (just below that) to specify that a UnicodeLetter can be any character from the unicode catagories, Lo, Ll, Lu, Lt, Lm and Nl. And when you look up those catagories you will see that this opens up a lot more possibilities than just latin letters. Just search for "unicode catagories" in google and you can find them.

Note that -p is an argument to the mkdir command specifically, not the whole of Unix. Every command can have whatever arguments it needs.

In this case it means "parents", meaning mkdir will create a directory and any parents that don't already exist.

A verbose equivalent is to combine $LASTEXITCODE and -eq 0:

msbuild.exe args; if ($LASTEXITCODE -eq 0) { echo 'it built'; } else { echo 'it failed'; }

I'm not sure why if ($?) didn't work for me, but this one did.

If you would like to make the command once for your entire site, instead of having to do it after every link. Try this place within the Head of your web site and bingo.

<head>
<title>your text</title>
<base target="_blank" rel="noopener noreferrer">

Im Fixed with this way.

its very simple. only pass a string its remove zero start of string.

function removeZeroString($str='')
{
    while(trim(substr($str,0,1)) === '0')
    {
        $str = ltrim($str,'0');
    }
    return $str;
}

You could just capture window resize events and set the size of your canvas to be the browser's viewport.

What I do in my projects is to activate the following option in the "Constant conditions & exceptions" code inspection:
Suggest @Nullable annotation for methods that may possibly return null and report nullable values passed to non-annotated parameters

When activated, all non-annotated parameters will be treated as non-null and thus you will also see a warning on your indirect call:

clazz.indirectPathToA(null); 

For even stronger checks the Checker Framework may be a good choice (see this nice tutorial.
Note: I have not used that yet and there may be problems with the Jack compiler: see this bugreport

Mine showed up in VS2010 after writing the first parenthesis..

so, prams.Add(

After doings something like that, the box with the up and down arrows appeared.

Note that "number of cores" might not be a particularly useful number, you might have to qualify it a bit more. How do you want to count multi-threaded CPUs such as Intel HT, IBM Power5 and Power6, and most famously, Sun's Niagara/UltraSparc T1 and T2? Or even more interesting, the MIPS 1004k with its two levels of hardware threading (supervisor AND user-level)... Not to mention what happens when you move into hypervisor-supported systems where the hardware might have tens of CPUs but your particular OS only sees a few.

The best you can hope for is to tell the number of logical processing units that you have in your local OS partition. Forget about seeing the true machine unless you are a hypervisor. The only exception to this rule today is in x86 land, but the end of non-virtual machines is coming fast...

Just combine the text files and then use something like the YUI Compressor.

Files can be easily combined using the command cat *.js > main.js and main.js can then be run through the YUI compressor using java -jar yuicompressor-x.y.z.jar -o main.min.js main.js.

Update Aug 2014

I've now migrated to using Gulp for javascript concatenation and compression as with various plugins and some minimal configuration you can do things like set up dependencies, compile coffeescript etc as well as compressing your JS.

If you are using the new Navigation Component, is simple as

findNavController().popBackStack()

It will do all the FragmentTransaction in behind for you.

You can temporarily disable foreign key checks:

SET FOREIGN_KEY_CHECKS=0;

Just be sure to restore them once you’re done messing around:

SET FOREIGN_KEY_CHECKS=1;

Check out Refit for making calls to REST services from .NET. I've found it very easy to use:

Refit: The automatic type-safe REST library for .NET Core, Xamarin and .NET

Refit is a library heavily inspired by Square's Retrofit library, and it turns your REST API into a live interface:

public interface IGitHubApi {
        [Get("/users/{user}")]
        Task<User> GetUser(string user);
}

// The RestService class generates an implementation of IGitHubApi
// that uses HttpClient to make its calls:

var gitHubApi = RestService.For<IGitHubApi>("https://api.github.com");

var octocat = await gitHubApi.GetUser("octocat");

In case if one is using nginx proxy as a docker container (e.g. jwilder/nginx-proxy), there is the following way to configure client_max_body_size (or other properties):

1. Create a custom config file e.g. /etc/nginx/proxy.conf with a right value for this property
2. When running a container, add it as a volume e.g. -v /etc/nginx/proxy.conf:/etc/nginx/conf.d/my_proxy.conf:ro

Personally found this way rather convenient as there's no need to build a custom container to change configs. I'm not affiliated with jwilder/nginx-proxy, was just using it in my project, and the way described above helped me. Hope it helps someone else, too.

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/zGPuazETKkI?autoplay=1" frameborder="0" allowfullscreen></iframe>

?autoplay=1

&autoplay=1

its the first URL param so its added with a ?

char* str=NULL;
int len = asprintf(&str, "%g", float_var);
if (len == -1)
  fprintf(stderr, "Error converting float: %m\n");
else
  printf("float is %s\n", str);
free(str);

strcat(str1, str2) appends str2 after str1. It requires str1 to have enough space to hold str2. In you code, str1 and str2 are all string constants, so it should not work. You may try this way:

char str1[1024];
char *str2 = "kkkk";
strcpy(str1, "ssssss");
strcat(str1, str2);
printf("%s", str1);

If the sent_at field is not there when its not set then:

db.emails.count({sent_at: {$exists: false}})

If its there and null, or not there at all:

db.emails.count({sent_at: null})

Refer here for querying and null

Just as a follow up to comments on the efficiency of exponentiation by squaring.

The advantage of that approach is that it runs in log(n) time. For example, if you were going to calculate something huge, such as x^1048575 (2^20 - 1), you only have to go thru the loop 20 times, not 1 million+ using the naive approach.

Also, in terms of code complexity, it is simpler than trying to find the most optimal sequence of multiplications, a la Pramod's suggestion.

Edit:

I guess I should clarify before someone tags me for the potential for overflow. This approach assumes that you have some sort of hugeint library.

It takes keyword arguments for the variables:

url_for('add', variable=foo)

Add this code to you project and use the object-style inArray methods

if (!Array.prototype.inArray) {
    Array.prototype.inArray = function(element) {
        return this.indexOf(element) > -1;
    };
} 
//How it work
var array = ["one", "two", "three"];
//Return true
array.inArray("one");

First rule of threading - "Threading is fun"...

I'm not able to understand the flow of execution of the program, And when ob1 is created then the constructor is called where t.start() is written but still run() method is not executed rather main() method continues execution. So why is this happening?

This is exactly what should happen. When you call Thread#start, the thread is created and schedule for execution, it might happen immediately (or close enough to it), it might not. It comes down to the thread scheduler.

This comes down to how the thread execution is scheduled and what else is going on in the system. Typically, each thread will be given a small amount of time to execute before it is put back to "sleep" and another thread is allowed to execute (obviously in multiple processor environments, more than one thread can be running at time, but let's try and keep it simple ;))

Threads may also yield execution, allow other threads in the system to have chance to execute.

You could try

NewThread(String threadname) {
    name = threadname;
    t = new Thread(this, name);
    System.out.println("New thread: " + t);
    t.start(); // Start the thread
    // Yield here
    Thread.yield();
}

And it might make a difference to the way the threads run...equally, you could sleep for a small period of time, but this could cause your thread to be overlooked for execution for a period of cycles (sometimes you want this, sometimes you don't)...

join() method is used to wait until the thread on which it is called does not terminates, but here in output we see alternate outputs of the thread why??

The way you've stated the question is wrong...join will wait for the Thread it is called on to die before returning. For example, if you depending on the result of a Thread, you could use join to know when the Thread has ended before trying to retrieve it's result.

Equally, you could poll the thread, but this will eat CPU cycles that could be better used by the Thread instead...

Use SELECT or an output parameter. More can be found here: http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=100201

Under Windows7 Pro, I found that Arun's solution worked for me: I could get this to work even with "no user logged on", I did choose use highest priveledges.

From past experience, you must have an account with a password (blank passwords are no good), and if the program doesn't prompt you for the password when you finish the wizard, go back in and edit something till it does!

This is the method in case its not clear which worked

Action: start a program
Program/script : cmd
      (doesn't need the .exe bit!)
Add arguments:
    /c start "" "E:\Django-1.4.1\setup.bat" 

In my case form Data was data , fire base was expecting an object but data contains object as well as all other stuffs so i tried data.value it worked!!!

Specifying auto on width and height elements is the same as removing them, technically. Using vanilla Javascript:

images[i].style.height = "auto";
images[i].style.width = "auto";

$ svn copy http://svn.example.com/repos/calc/trunk@192 \
   http://svn.example.com/repos/calc/branches/my-calc-branch \
   -m "Creating a private branch of /calc/trunk."

Where 192 is the revision you specify

You can find this information from the SVN Book, specifically here on the page about svn copy

Its quite old question, and I'm not sure if it was an option at that time, but this is the reason why I always prefer DependencyInjection by the constructor than by the value.

I can imagine that your class might look like this:

class ExampleClass{

   @Autowired
   private Dog dog;

   @Value("${this.property.value}") 
   private String thisProperty;

   ...other stuff...
}

You can change it to:

class ExampleClass{

   private Dog dog;
   private String thisProperty;

   //optionally @Autowire
   public ExampleClass(final Dog dog, @Value("${this.property.value}") final String thisProperty){
      this.dog = dog;
      this.thisProperty = thisProperty;
   }

   ...other stuff...
}

With this implementation, the spring will know what to inject automatically, but for unit testing, you can do whatever you need. For example Autowire every dependency wth spring, and inject them manually via constructor to create "ExampleClass" instance, or use only spring with test property file, or do not use spring at all and create all object yourself.

If you merely wish to remove changes to existing files, use checkout (documented here).

git checkout -- .

• The double-hyphen (--) tells Git that what follows should be taken as its second argument (path), that you skipped specification of a branch.
• The period (.) indicates all paths.

If you want to remove files added since your last commit, use clean (documented here):

git clean -i 

• The -i option initiates an interactive clean, to prevent mistaken deletions.
• A handful of other options are available for a quicker execution; see the documentation.

If you wish to move changes to a holding space for later access, use stash (documented here):

git stash

• All changes will be moved to Git's Stash, for possible later access.
• A handful of options are available for more nuanced stashing; see the documentation.

Add XML comments to the publicly visible types and members of course :)

///<Summary>
/// Gets the answer
///</Summary>
public int MyMethod()
{
   return 42;
}

You need these <summary> type comments on all members - these also show up in the intellisense popup menu.

The reason you get this warning is because you've set your project to output documentation xml file (in the project settings). This is useful for class libraries (.dll assemblies) which means users of your .dll are getting intellisense documentation for your API right there in visual studio.

I recommend you get yourself a copy of the GhostDoc Visual Studio AddIn.. Makes documenting much easier.
