Another one-liner using Python swapping:

df, df.columns = df[1:] , df.iloc[0]

This won't reset the index

Although, the opposite won't work as expected df.columns, df = df.iloc[0], df[1:]

Sadly there are no operation-assignment operators in VBA.

(Addition-assignment += are available in VB.Net)

Pointless workaround;

Sub Inc(ByRef i As Integer)
   i = i + 1  
End Sub
...
Static value As Integer
inc value
inc value

Yes, use mktemp.

It will create a temporary file inside a folder that is designed for storing temporary files, and it will guarantee you a unique name. It outputs the name of that file:

> mktemp
/tmp/tmp.xx4mM3ePQY
>

It's also used in Ruby 'Enterprise Edition' as a neat way of saving memory.

stdout is the standard output file stream. Obviously, it's first and default pointer to output is the screen, however you can point it to a file as desired!

Please read:

C++ is very similar to C however, object oriented.

gettimeofday - the problem is that will can have lower values if you change you hardware clock (with NTP for example) Boost - not available for this project clock() - usually returns a 4 bytes integer, wich means that its a low capacity, and after some time it returns negative numbers.

I prefer to create my own class and update each 10 miliseconds, so this way is more flexible, and I can even improve it to have subscribers.

class MyAlarm {
static int64_t tiempo;
static bool running;
public:
static int64_t getTime() {return tiempo;};
static void callback( int sig){
    if(running){
        tiempo+=10L;
    }
}
static void run(){ running = true;}
};

int64_t MyAlarm::tiempo = 0L;
bool MyAlarm::running = false;

to refresh it I use setitimer:

int main(){
struct sigaction sa; 
struct itimerval timer; 

MyAlarm::run();
memset (&sa, 0, sizeof (sa)); 
sa.sa_handler = &MyAlarm::callback; 

sigaction (SIGALRM, &sa, NULL); 


timer.it_value.tv_sec = 0; 
timer.it_value.tv_usec = 10000; 



timer.it_interval.tv_sec = 0; 
timer.it_interval.tv_usec = 10000; 


setitimer (ITIMER_REAL, &timer, NULL); 
.....

Look at setitimer and the ITIMER_VIRTUAL and ITIMER_REAL.

Don't use the alarm or ualarm functions, you will have low precision when your process get a hard work.

Ken Clark's answer didn't work in my case. It might not work in yours either. If not, try this:

SELECT * 
from table T

INNER JOIN
  (
  select id, MIN(point) MinPoint
  from table T
  group by AccountId
  ) NewT on T.id = NewT.id and T.point = NewT.MinPoint

ORDER BY game desc

As pointed out, you cannot set arbitrary inline styles for hover, but you can change the style of the hover cursor in CSS using the following in the appropriate tag:

style="cursor: pointer;"

I solved it with library PHP_PDO , because my hosting provider didn't accept my requirement for installation of PDO driver to apache server.

You are opening the file as "w", which stands for writable.

Using "w" you won't be able to read the file. Use the following instead:

file = open("File.txt","r")

Additionally, here are the other options:

"r"   Opens a file for reading only.
"r+"  Opens a file for both reading and writing.
"rb"  Opens a file for reading only in binary format.
"rb+" Opens a file for both reading and writing in binary format.
"w"   Opens a file for writing only.
"a"   Open for writing.  The file is created if it does not exist.
"a+"  Open for reading and writing.  The file is created if it does not exist.

I found a solution using AutoLayout in StoryBoard.

1) Set no of lines to 0 and text alignment to Left.

2) Set height constraint.

3) The height Constraint should be in Relation - Less Than or Equal

4)

   override func viewWillLayoutSubviews() {
        sampleLabel.sizeToFit()
    }

I got the result as follows :

Don't use == use .equals.

try this instead (IIRC, ZipCode needs to implement Comparable for this to work.

boolean unique;
Set<ZipCode> s = new TreeSet<ZipCode>();
for( ZipCode zc : zipcodelist )
    unique||=s.add(zc);
duplicates = !unique;

You are first setting opacity: 1; and then you are ending it on 0, so it starts from 0% and ends on 100%, so instead just set opacity to 0 at 50% and the rest will take care of itself.

Demo

.blink_me {_x000D_
  animation: blinker 1s linear infinite;_x000D_
}_x000D_
_x000D_
@keyframes blinker {_x000D_
  50% {_x000D_
    opacity: 0;_x000D_
  }_x000D_
}

<div class="blink_me">BLINK ME</div>

Here, I am setting the animation duration to be 1 second, and then I am setting the timing to linear. That means it will be constant throughout. Last, I am using infinite. That means it will go on and on.

Note: If this doesn't work for you, use browser prefixes like -webkit, -moz and so on as required for animation and @keyframes. You can refer to my detailed code here

As commented, this won't work on older versions of Internet Explorer, and for that you need to use jQuery or JavaScript...

(function blink() {
  $('.blink_me').fadeOut(500).fadeIn(500, blink);
})();

^{Thanks to Alnitak for suggesting a better approach.}

Demo (Blinker using jQuery)

Caution, member enumeration only works if the collection itself has no member of the same name. So if you had an array of FileInfo objects, you couldn't get an array of file lengths by using

 $files.length # evaluates to array length

And before you say "well obviously", consider this. If you had an array of objects with a capacity property then

 $objarr.capacity

would work fine UNLESS $objarr were actually not an [Array] but, for example, an [ArrayList]. So before using member enumeration you might have to look inside the black box containing your collection.

(Note to moderators: this should be a comment on rageandqq's answer but I don't yet have enough reputation.)

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

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

Try this one:

var data = [{id: 1, text: 'First'}, {id: 2, text: 'Second'}, {...}];
$('select[name="my_select"]').empty().select2({
    data: data
});

You can also set locale to your region and set float_format to use a currency format. This will automatically set $ sign for currency in USA.

import locale

locale.setlocale(locale.LC_ALL, "en_US.UTF-8")

pd.set_option("float_format", locale.currency)

df = pd.DataFrame(
    [123.4567, 234.5678, 345.6789, 456.7890],
    index=["foo", "bar", "baz", "quux"],
    columns=["cost"],
)
print(df)

        cost
foo  $123.46
bar  $234.57
baz  $345.68
quux $456.79

As a complementary, to produce patch for only one specific commit, use:

git format-patch -1 <sha>

When the patch file is generated, make sure your other repo knows where it is when you use git am ${patch-name}

Before adding the patch, use git apply --check ${patch-name} to make sure that there is no confict.

Thanks jbaliuka for the suggestion. I opened the registry editor (by typing regedit in cmd) and going to HKEY_CLASSES_ROOT > jarfile > shell > open > command, then opening (Default) and changing the value from

"C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

to

"C:\Program Files\Java\jre7\bin\java.exe" -jar "%1" %*

(I just removed the w in javaw.exe.) After that you have to right click a jar -> open with -> choose default program -> navigate to your java folder and open \jre7\bin\java.exe (or any other java.exe file in you java folder). If it doesn't work, try switching to javaw.exe, open a jar file with it, then switch back.

I don't know anything about editing the registry except that it's dangerous, so you might wanna back it up before doing this (in the top bar, File>Export).

You can call the scp bash command (it copies files over SSH) with subprocess.run:

import subprocess
subprocess.run(["scp", FILE, "USER@SERVER:PATH"])
#e.g. subprocess.run(["scp", "foo.bar", "[email protected]:/path/to/foo.bar"])

If you're creating the file that you want to send in the same Python program, you'll want to call subprocess.run command outside the with block you're using to open the file (or call .close() on the file first if you're not using a with block), so you know it's flushed to disk from Python.

You need to generate (on the source machine) and install (on the destination machine) an ssh key beforehand so that the scp automatically gets authenticated with your public ssh key (in other words, so your script doesn't ask for a password).

That seems to work for me:

<html>
<head><style>
#monkey {color:blue}
#ape {color:purple}
</style></head>
<body>
<span id="monkey" onclick="changeid()">
fruit
</span>
<script>
function changeid ()
{
var e = document.getElementById("monkey");
e.id = "ape";
}
</script>
</body>
</html>

The expected behaviour is to change the colour of the word "fruit".

Perhaps your document was not fully loaded when you called the routine?

i faced the same problem , the solution worked for me , hope it will work for you too.

<script src="content/js/jquery.min.js"></script>
<script src="content/js/bootstrap.min.js"></script>
<script>
    $(document).ready(function () {
        $('.dropdown-toggle').dropdown();
    });
</script>

Please include the "jquery.min.js" file before "bootstrap.min.js" file, if you shuffle the order it will not work.

In some version of numpy there is another imporant difference that you must be aware:

average do not take in account masks, so compute the average over the whole set of data.

mean takes in account masks, so compute the mean only over unmasked values.

g = [1,2,3,55,66,77]
f = np.ma.masked_greater(g,5)

np.average(f)
Out: 34.0

np.mean(f)
Out: 2.0

How about run a command line:

require('child_process').execSync('rm -rf /path/to/directory/*')

C++11 N3337 standard draft

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3337.pdf

19.3 Assertions

1 The header <cassert>, described in (Table 42), provides a macro for documenting C ++ program assertions and a mechanism for disabling the assertion checks.

2 The contents are the same as the Standard C library header <assert.h>.

C99 N1256 standard draft

http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1256.pdf

7.2 Diagnostics <assert.h>

1 The header <assert.h> defines the assert macro and refers to another macro, NDEBUG which is not defined by <assert.h>. If NDEBUG is defined as a macro name at the point in the source file where <assert.h> is included, the assert macro is defined simply as

 #define assert(ignore) ((void)0)

The assert macro is redefined according to the current state of NDEBUG each time that <assert.h> is included.

2. The assert macro shall be implemented as a macro, not as an actual function. If the macro definition is suppressed in order to access an actual function, the behavior is undefined.

7.2.1 Program diagnostics

7.2.1.1 The assert macro

Synopsis

1.

#include <assert.h>
void assert(scalar expression);

Description

2 The assert macro puts diagnostic tests into programs; it expands to a void expression. When it is executed, if expression (which shall have a scalar type) is false (that is, compares equal to 0), the assert macro writes information about the particular call that failed (including the text of the argument, the name of the source file, the source line number, and the name of the enclosing function — the latter are respectively the values of the preprocessing macros __FILE__ and __LINE__ and of the identifier __func__) on the standard error stream in an implementation-defined format. 165) It then calls the abort function.

Returns

3 The assert macro returns no value.

Your file should be available as com/example/foo/myProps.properties in classpath. Then load it as:

props.load(this.getClass().getResourceAsStream("myProps.properties"));

comment out both "Default env_reset" and "Default secure_path ..." in /etc/sudores file works for me

You could try using json-lib's JSONAssert class:

JSONAssert.assertEquals(
  "{foo: 'bar', baz: 'qux'}",
  JSONObject.fromObject("{foo: 'bar', baz: 'xyzzy'}")
);

Gives:

junit.framework.ComparisonFailure: objects differed at key [baz]; expected:<[qux]> but was:<[xyzzy]>

If you don't know the number of columns ahead of time, add each column to a list and cbind at the end.

List <- list()
for(i in 1:n)
{
    normF <- #something
    List[[i]] <- normF
}
Matrix = do.call(cbind, List)

u can make

'xxxx' text u search and will replace it with 'yyyy'

grep -Rn '**xxxx**' /path | awk -F: '{print $1}' | xargs sed -i 's/**xxxx**/**yyyy**/'

We were using:

mongoose.connect("mongodb://localhost/mean-course").then(
  (res) => {
   console.log("Connected to Database Successfully.")
  }
).catch(() => {
  console.log("Connection to database failed.");
});

? This gives a URL parser error

The correct syntax is:

mongoose.connect("mongodb://localhost:27017/mean-course" , { useNewUrlParser: true }).then(
  (res) => {
   console.log("Connected to Database Successfully.")
  }
).catch(() => {
  console.log("Connection to database failed.");
});

You need to make sure if package.json file exist in app folder. i run into same problem differently but solution would be same

Run this command where "package.json" file exist. even i experience similar problem then i change the folder and got resolve it. for more explanation i run c:\selfPractice> npm start whereas my package.json resides in c:\selfPractice\frontend> then i change the folder and run c:\selfPractice\frontend> npm start and it got run

After a few years of working with GPS on windows mobile, I realized that the concept of "losing" a GPS fix can be subjective. To simply listen to what the GPS tells you, adding a NMEAListener and parsing the sentence will tell you whether the fix was "valid" or not. See http://www.gpsinformation.org/dale/nmea.htm#GGA . Unfortunately with some GPSes this value will fluctuate back and forth even during the normal course of operation in a "good fix" area.

So, the other solution is to compare the UTC time of the GPS location against the phone's time (converted to UTC). If they are a certain time difference apart, you can assume you lost the GPS position.

Open psql command line and type :

This question shows precisely why I like to do things the way I mentioned in my question is const after type id acceptable?

In short, I find the easiest way to remember the rule is that the "const" goes after the thing it applies to. So in your question, "int const *" means that the int is constant, while "int * const" would mean that the pointer is constant.

If someone decides to put it at the very front (eg: "const int *"), as a special exception in that case it applies to the thing after it.

Many people like to use that special exception because they think it looks nicer. I dislike it, because it is an exception, and thus confuses things.

If you are already using Fabric/Firebase Crashlytics you can call

CommonUtils.isRooted(context)

This is the current implementation of that method:

public static boolean isRooted(Context context) {
    boolean isEmulator = isEmulator(context);
    String buildTags = Build.TAGS;
    if(!isEmulator && buildTags != null && buildTags.contains("test-keys")) {
        return true;
    } else {
        File file = new File("/system/app/Superuser.apk");
        if(file.exists()) {
            return true;
        } else {
            file = new File("/system/xbin/su");
            return !isEmulator && file.exists();
        }
    }
}

HOW TO IMPLEMENT 'insert if not exist'?

1. REPLACE INTO

pros:

1. simple.

cons:

1. too slow.

2. auto-increment key will CHANGE(increase by 1) if there is entry matches unique key or primary key, because it deletes the old entry then insert new one.

2. INSERT IGNORE

pros:

1. simple.

cons:

1. auto-increment key will not change if there is entry matches unique key or primary key but auto-increment index will increase by 1

2. some other errors/warnings will be ignored such as data conversion error.

3. INSERT ... ON DUPLICATE KEY UPDATE

pros:

1. you can easily implement 'save or update' function with this

cons:

1. looks relatively complex if you just want to insert not update.

2. auto-increment key will not change if there is entry matches unique key or primary key but auto-increment index will increase by 1

4. Any way to stop auto-increment key increasing if there is entry matches unique key or primary key?

As mentioned in the comment below by @toien: "auto-increment column will be effected depends on innodb_autoinc_lock_mode config after version 5.1" if you are using innodb as your engine, but this also effects concurrency, so it needs to be well considered before used. So far I'm not seeing any better solution.

For me it didn't work , it was related to a path problem happened after android studio 2.0 preview 1, I needed to update genymotion and virtual box, and apparently they tried to use same port for adb.

Solution is explained here link! Basically you just need to:

1) open genymotion settings

2) specify sdk path for the adb manually

3) adb kill-server

4) adb start-server

See an example here: http://www.cplusplus.com/reference/stl/vector/insert/ eg.:

...
vector::iterator iterator1;

  iterator1= vec1.begin();
  vec1.insert ( iterator1+i , vec2[i] );

// This means that at position "i" from the beginning it will insert the value from vec2 from position i

Your first approach was replacing the values from vec1[i] with the values from vec2[i]

For those using CygWin on Vista, Win7, or above, the native git command can create "proper" symlinks that are recognized by Windows apps such as Android Studio. You just need to set the CYGWIN environment variable to include winsymlinks:native or winsymlinks:nativestrict as such:

export CYGWIN="$CYGWIN winsymlinks:native"

The downside to this (and a significant one at that) is that the CygWin shell has to be "Run as Administrator" in order for it to have the OS permissions required to create those kind of symlinks. Once they're created, though, no special permissions are required to use them. As long they aren't changed in the repository by another developer, git thereafter runs fine with normal user permissions.

Personally, I use this only for symlinks that are navigated by Windows apps (i.e. non-CygWin) because of this added difficulty.

For more information on this option, see this SO question: How to make symbolic link with cygwin in Windows 7

I had this problem where .mp4 playback in Safari didn't work, but in other browsers it was fine. The error that I was seeing in the console was: error media src not supported. In my case this turned out to be a MIME type issue, but not because it wasn't declared as MIME type in IIS, rather that it was declared twice (once in IIS and also in a web.config file). I found this out by trying to download the .mp4 file locally on the server. I removed the config file from the location of the content I was trying to play and it fixed the issue. I could have just deleted the MIME type from the web.config file, but in this case the web.config file wasn't needed.

MySQL 5.x specification for decimal datatype is: DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL]. The answer above is wrong (now corrected) in saying that unsigned decimals are not possible.

To define a field allowing only unsigned decimals, with a total length of 6 digits, 4 of which are decimals, you would use: DECIMAL (6,4) UNSIGNED.

You can likewise create unsigned (ie. not negative) FLOAT and DOUBLE datatypes.

Update on MySQL 8.0.17+, as in MySQL 8 Manual: 11.1.1 Numeric Data Type Syntax:

"Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.*

As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms); you should expect support for it to be removed in a future version of MySQL. Consider using a simple CHECK constraint instead for such columns.

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

I'm using something like this:

String scheme = uri.getScheme();
if (scheme.equals("file")) {
    fileName = uri.getLastPathSegment();
}
else if (scheme.equals("content")) {
    String[] proj = { MediaStore.Images.Media.TITLE };
    Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
    if (cursor != null && cursor.getCount() != 0) {
        int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.TITLE);
        cursor.moveToFirst();
        fileName = cursor.getString(columnIndex);
    }
    if (cursor != null) {
        cursor.close();
    }
}

Use the following representation instead:

local items = { apple=true, orange=true, pear=true, banana=true }
if items.apple then
    ...
end

function seconds_to_time($seconds){
     // extract hours
    $hours = floor($seconds / (60 * 60));

    // extract minutes
    $divisor_for_minutes = $seconds % (60 * 60);
    $minutes = floor($divisor_for_minutes / 60);

    // extract the remaining seconds
    $divisor_for_seconds = $divisor_for_minutes % 60;
    $seconds = ceil($divisor_for_seconds);

    //create string HH:MM:SS
    $ret = $hours.":".$minutes.":".$seconds;
    return($ret);
}

From what I understand, an Interface, which is comprised of final variables and methods with no implementations, is implemented by a class to obtain a group of methods or methods that are related to each other. On the other hand, an abstract class, which can contain non-final variables and methods with implementations, is usually used as a guide or as a superclass from which all related or similar classes inherits from. In other words, an abstract class contains all the methods/variables that are shared by all its subclasses.

There are 2 possible solutions that I personally use

1.without using form

 <button type="submit" value={{excel_path}} onclick="location.href='{% url 'downloadexcel' %}'" name='mybtn2'>Download Excel file</button>

2.Using Form

<form action="{% url 'downloadexcel' %}" method="post">
{% csrf_token %}


 <button type="submit" name='mybtn2' value={{excel_path}}>Download results in Excel</button>
 </form>

Where urls.py should have this

path('excel/',views1.downloadexcel,name="downloadexcel"),

You can use Regex.Match

if(text.matches("\\d*")&& text.length() > 2){
    System.out.println("number");
}

Or you could use onversions like Integer.parseInt(String) or better Long.parseLong(String) for bigger numbers like for example:

private boolean onlyContainsNumbers(String text) {
    try {
        Long.parseLong(text);
        return true;
    } catch (NumberFormatException ex) {
        return false;
    }
} 

And then test with:

if (onlyContainsNumbers(text) && text.length() > 2) {
    // do Stuff
}

The onload event does not always work on IE7/8 in <head> ... </head>

You can force it by adding an onload script at the end of your page before the tag as below.

  <script>
    window.onload();
  </script>
</body>

By calling setTimeout you give the page time to react to the whatever the user is doing. This is particularly helpful for functions run during page load.

That's not the way to concat in MYSQL. Use the CONCAT function Have a look here: http://dev.mysql.com/doc/refman/4.1/en/string-functions.html#function_concat

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

Append "empty" row to data frame and fill selected cells:

Generate empty data frame (no rows just columns a and b):

import pandas as pd    
col_names =  ["a","b"]
df  = pd.DataFrame(columns = col_names)

Append empty row at the end of the data frame:

df = df.append(pd.Series(), ignore_index = True)

Now fill the empty cell at the end (len(df)-1) of the data frame in column a:

df.loc[[len(df)-1],'a'] = 123

Result:

     a    b
0  123  NaN

And of course one can iterate over the rows and fill cells:

col_names =  ["a","b"]
df  = pd.DataFrame(columns = col_names)
for x in range(0,5):
    df = df.append(pd.Series(), ignore_index = True)
    df.loc[[len(df)-1],'a'] = 123

Result:

     a    b
0  123  NaN
1  123  NaN
2  123  NaN
3  123  NaN
4  123  NaN

SQL Server autocreates indices for Primary Keys, but not for Foreign Keys. Create the index for the Foreign Keys. It's probably worth the overhead.

The solution:

error : The requested URL returned error : 503 while Accessing

The error might be resolved by deleting the existing git folder.

How do you 'tag' a particular set of revisions

How do you 'mark' 'tag' or 'release' a particular set of revisions for a particular set of files so you can always pull that one later?

Using the git tag command.

To simply "tag" the current revision, you would just run..

git tag -a thetagname
git tag -a 0.1
git tag -a 2.6.1-rc1 -m 'Released on 01/02/03'

To list the current tags, simply run git tag with no arguments, or -l (lower case L):

$ git tag -a thetagname # and enter a message, or use -m 'My tag annotation'
$ git tag -l
thetagname

To delete a tag, you use the -d flag:

$ git tag -d thetagname 
Deleted tag 'thetagname'
$ git tag
[no output]

To tag a specific (previous) commit, you simply do..

git tag [tag name] [revision SHA1 hash]

For example:

git tag 1.1.1 81b15a68c6c3e71f72e766931df4e6499990385b

Note: by default, git creates a "lightweight" tag (basically a reference to a specific revision). The "right" way is to use the -a flag. This will launch your editor asking for a tag message (identical to asking for a commit message, you can also use the -m flag to supply the tag message on the command line). Using an annotated tag creates an object with its own ID, date, tagger (author), and optionally a GPG signature (using the -s tag). For further information on this, see this post

git tag mytagwithmsg -a -m 'This is a tag, with message'

And to list the tags with annotations, use the -n1 flag to show 1 line of each tag message (-n245 to show the first 245 lines of each annotation, and so on):

$ git tag -l -n1
mytagwithmsg    This is a tag, with message

For more information, see the git-tag(1) Manual Page

I've tried all the above, but nothing seems to work as expected. After a little research I found that e.relatedTarget is the html just before the mouse exits the window.

So ... I've end up with this:

document.body.addEventListener('mouseout', function(e) {
    if (e.relatedTarget === document.querySelector('html')) {
        console.log('We\'re OUT !');
    }
});

Please let me know if you find any issues or improvements !

2019 Update

(as user1084282 found out)

document.body.addEventListener('mouseout', function(e) {
    if (!e.relatedTarget && !e.toElement) {
        console.log('We\'re OUT !');
    }
});

Epsilon is a difference between expected and actual values which you can accept thinking they are equal. You can set .1 for example.

You could use some third party open-source libraries to generated strong typed verified (X)HTML, such as CityLizard Framework or Sharp DOM.

Update For example

        [title["Title of the page"]]

Just another answer to explain some subtle points in the code of the other answers:

• socket.INADDR_ANY - (Edited) In the context of IP_ADD_MEMBERSHIP, this doesn't really bind the socket to all interfaces but just choose the default interface where multicast is up (according to routing table)
• Joining a multicast group isn't the same as binding a socket to a local interface address

see What does it mean to bind a multicast (UDP) socket? for more on how multicast works

Multicast receiver:

import socket
import struct
import argparse


def run(groups, port, iface=None, bind_group=None):
    # generally speaking you want to bind to one of the groups you joined in
    # this script,
    # but it is also possible to bind to group which is added by some other
    # programs (like another python program instance of this)

    # assert bind_group in groups + [None], \
    #     'bind group not in groups to join'
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)

    # allow reuse of socket (to allow another instance of python running this
    # script binding to the same ip/port)
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

    sock.bind(('' if bind_group is None else bind_group, port))
    for group in groups:
        mreq = struct.pack(
            '4sl' if iface is None else '4s4s',
            socket.inet_aton(group),
            socket.INADDR_ANY if iface is None else socket.inet_aton(iface))

        sock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, mreq)

    while True:
        print(sock.recv(10240))


if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('--port', type=int, default=19900)
    parser.add_argument('--join-mcast-groups', default=[], nargs='*',
                        help='multicast groups (ip addrs) to listen to join')
    parser.add_argument(
        '--iface', default=None,
        help='local interface to use for listening to multicast data; '
        'if unspecified, any interface would be chosen')
    parser.add_argument(
        '--bind-group', default=None,
        help='multicast groups (ip addrs) to bind to for the udp socket; '
        'should be one of the multicast groups joined globally '
        '(not necessarily joined in this python program) '
        'in the interface specified by --iface. '
        'If unspecified, bind to 0.0.0.0 '
        '(all addresses (all multicast addresses) of that interface)')
    args = parser.parse_args()
    run(args.join_mcast_groups, args.port, args.iface, args.bind_group)

sample usage: (run the below in two consoles and choose your own --iface (must be same as the interface that receives the multicast data))

python3 multicast_recv.py --iface='192.168.56.102' --join-mcast-groups '224.1.1.1' '224.1.1.2' '224.1.1.3' --bind-group '224.1.1.2'

python3 multicast_recv.py --iface='192.168.56.102' --join-mcast-groups '224.1.1.4'

Multicast sender:

import socket
import argparse


def run(group, port):
    MULTICAST_TTL = 20
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
    sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, MULTICAST_TTL)
    sock.sendto(b'from multicast_send.py: ' +
                f'group: {group}, port: {port}'.encode(), (group, port))


if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('--mcast-group', default='224.1.1.1')
    parser.add_argument('--port', default=19900)
    args = parser.parse_args()
    run(args.mcast_group, args.port)

sample usage: # assume the receiver binds to the below multicast group address and that some program requests to join that group. And to simplify the case, assume the receiver and the sender are under the same subnet

python3 multicast_send.py --mcast-group '224.1.1.2'

python3 multicast_send.py --mcast-group '224.1.1.4'

for (var i in a) {
   console.log(a[i],i)
}

You use the id property to the get the id, then the substr method to remove the first part of it, then optionally parseInt to turn it into a number:

var id = theElement.id.substr(5);

or:

var id = parseInt(theElement.id.substr(5));

I was interested to see that the original poster used a style that avoided early exits. Single Entry; Single Exit (SESE) is an interesting style that I've not really explored. It's late and I've got a bottle of cider, so I've written a solution (not tested) without an early exit.

I should have used an iterator. Unfortunately java.util.Iterator has a side-effect in the get method. (I don't like the Iterator design due to its exception ramifications.)

private Dog findDog(int id) {
    int i = 0;
    for (; i!=dogs.length() && dogs.get(i).getID()!=id; ++i) {
        ;
    }

    return i!=dogs.length() ? dogs.get(i) : null;
}

Note the duplication of the i!=dogs.length() expression (could have chosen dogs.get(i).getID()!=id).

Check following to help the understand the concept of CTE recursion

DECLARE

@endDate DATETIME

SET @startDate = '11/10/2011'
SET @endDate = '03/25/2012'

; WITH CTE AS (
    SELECT

Try getppid() if you want your C program to print your shell's PID.

In the latest GitHub client for Windows, if you have uncommitted changes, and choose to create a new branch.
It prompts you how to handle this exact scenario:

The same applies if you simply switch the branch too.

A simple intuitive implementation

public static List<PointF> RemoveDuplicates(List<PointF> listPoints)
{
    List<PointF> result = new List<PointF>();

    for (int i = 0; i < listPoints.Count; i++)
    {
        if (!result.Contains(listPoints[i]))
            result.Add(listPoints[i]);
    }

    return result;
}

If you'd like to check if the argument exists, you can check if the # of arguments is greater than or equal to your target argument number.

The following script demonstrates how this works

test.sh

#!/usr/bin/env bash

if [ $# -ge 3 ]
then
  echo script has at least 3 arguments
fi

produces the following output

$ ./test.sh
~
$ ./test.sh 1
~
$ ./test.sh 1 2
~
$ ./test.sh 1 2 3
script has at least 3 arguments
$ ./test.sh 1 2 3 4
script has at least 3 arguments

Random item selection:

import random

my_list = [1, 2, 3, 4, 5]
num_selections = 2

new_list = random.sample(my_list, num_selections)

To preserve the order of the list, you could do:

randIndex = random.sample(range(len(my_list)), n_selections)
randIndex.sort()
new_list = [my_list[i] for i in randIndex]

Perhaps it would help to know does it mean for the hardware to be "designed for this environment". How does it correct and/or indicates the presence of SEU errors ?

At one space exploration related project, we had a custom MCU, which would raise an exception/interrupt on SEU errors, but with some delay, i.e. some cycles may pass/instructions be executed after the one insn which caused the SEU exception.

Particularly vulnerable was the data cache, so a handler would invalidate the offending cache line and restart the program. Only that, due to the imprecise nature of the exception, the sequence of insns headed by the exception raising insn may not be restartable.

We identified the hazardous (not restartable) sequences (like lw $3, 0x0($2), followed by an insn, which modifies $2 and is not data-dependent on $3), and I made modifications to GCC, so such sequences do not occur (e.g. as a last resort, separating the two insns by a nop).

Just something to consider ...

I just put --password flag into my command and after hitting Enter it asked me for password, which I supplied.

You can use the following script to convert jupyter notebook to Python script, or view the code directly.

To do this, write the following contents into a file cat_ipynb, then chmod +x cat_ipynb.

#!/usr/bin/env python
import sys
import json

for file in sys.argv[1:]:
    print('# file: %s' % file)
    print('# vi: filetype=python')
    print('')
    code = json.load(open(file))

    for cell in code['cells']:
        if cell['cell_type'] == 'code':
            print('# -------- code --------')
            for line in cell['source']:
                print(line, end='')
            print('\n')
        elif cell['cell_type'] == 'markdown':
            print('# -------- markdown --------')
            for line in cell['source']:
                print("#", line, end='')
            print('\n')

Then you can use

cat_ipynb your_notebook.ipynb > output.py

Or show it with vi directly

cat_ipynb your_notebook.ipynb | view -

If you have supporting indexes, and relatively high counts, something like this may be considerably faster than the solutions suggested:

SELECT name, MAX(Rcount) + MAX(Acount) AS TotalCount
FROM (
  SELECT name, COUNT(*) AS Rcount, 0 AS Acount
  FROM Results GROUP BY name
  UNION ALL
  SELECT name, 0, count(*)
  FROM Archive_Results
  GROUP BY name
) AS Both
GROUP BY name
ORDER BY name;

You probably should check this. Windows doesn't have that command built in.

There is no difference if we look on effect - value will be the same. However there is something more...

Solution 3:

function doSomething() {_x000D_
  console.log( theId.value );_x000D_
}

<input id="theId" value="test" onclick="doSomething()" />

if DOM element has id then you can use it in js directly

You are doing everything right, except passing your bundle path to asset() function.

According to documentation - in your example this should look like below:

{{ asset('bundles/webshome/css/main.css') }}

Tip: you also can call assets:install with --symlink key, so it will create symlinks in web folder. This is extremely useful when you often apply js or css changes (in this way your changes, applied to src/YouBundle/Resources/public will be immediately reflected in web folder without need to call assets:install again):

app/console assets:install web --symlink

Also, if you wish to add some assets in your child template, you could call parent() method for the Twig block. In your case it would be like this:

{% block stylesheets %}
    {{ parent() }}

    <link href="{{ asset('bundles/webshome/css/main.css') }}" rel="stylesheet">
{% endblock %}

Actually, you can achieve this pretty easy. Simply specify the line height as a number:

<p style="line-height:1.5">
    <span style="font-size:12pt">The quick brown fox jumps over the lazy dog.</span><br />
    <span style="font-size:24pt">The quick brown fox jumps over the lazy dog.</span>
</p>

The difference between number and percentage in the context of the line-height CSS property is that the number value is inherited by the descendant elements, but the percentage value is first computed for the current element using its font size and then this computed value is inherited by the descendant elements.

For more information about the line-height property, which indeed is far more complex than it looks like at first glance, I recommend you take a look at this online presentation.

This query help to find largest table in you are connection.

SELECT  TOP 1 OBJECT_NAME(OBJECT_ID) TableName, st.row_count
FROM sys.dm_db_partition_stats st
WHERE index_id < 2
ORDER BY st.row_count DESC

if (Value1.StartsWith("abc")) { found = true; }

go to... 
C:\wamp\alias

Inside alias folder you will see some files like phpmyadmin,phpsysinfo,etc...

open each file, and you can see inside file some commented instruction are give to access from outside ,like to give access to phpmyadmin from outside replace the lines

KeyboardInterrupt and signals are only seen by the process (ie the main thread)... Have a look at Ctrl-c i.e. KeyboardInterrupt to kill threads in python

The main concept of partial view is returning the HTML code rather than going to the partial view it self.

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

this action return the HTML code of the partial view ("HolidayPartialView").

To refresh partial view replace the existing item with the new filtered item using the jQuery below.

$.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });

This comment syntax should work for you:

@* enter comments here *@

If you only want the first element of a set (and you are certain there is at least one element) you can do the following:

<c:choose>
    <c:when test="${dealership.administeredBy.size() == 1}">
        Hello ${dealership.administeredBy.iterator().next().firstName},<br/>
    </c:when>
    <c:when test="${dealership.administeredBy.size() > 1}">
        Hello Administrators,<br/>
    </c:when>
    <c:otherwise>

Here's an implementation of the highest-voted answer that returns -1 when the item is not found:

public static int FindIndex<T>(this IEnumerable<T> items, Func<T, bool> predicate)
{
    var itemsWithIndices = items.Select((item, index) => new { Item = item, Index = index });
    var matchingIndices =
        from itemWithIndex in itemsWithIndices
        where predicate(itemWithIndex.Item)
        select (int?)itemWithIndex.Index;

    return matchingIndices.FirstOrDefault() ?? -1;
}

To delete untracked on *nix without the purge extension you can use

hg pull
hg update -r MY_BRANCH -C
hg status -un|xargs rm

Which is using

update -r --rev REV revision

update -C --clean discard uncommitted changes (no backup)

status -u --unknown show only unknown (not tracked) files

status -n --no-status hide status prefix

Java is not call by reference it is call by value only

But all variables of object type are actually pointers.

So if you use a Mutable Object you will see the behavior you want

public class XYZ {

    public static void main(String[] arg) {
        StringBuilder toyNumber = new StringBuilder("5");
        play(toyNumber);
        System.out.println("Toy number in main " + toyNumber);
    }

    private static void play(StringBuilder toyNumber) {
        System.out.println("Toy number in play " + toyNumber);
        toyNumber.append(" + 1");
        System.out.println("Toy number in play after increement " + toyNumber);
    }
}

Output of this code:

run:
Toy number in play 5
Toy number in play after increement 5 + 1
Toy number in main 5 + 1
BUILD SUCCESSFUL (total time: 0 seconds)

You can see this behavior in Standard libraries too. For example Collections.sort(); Collections.shuffle(); These methods does not return a new list but modifies it's argument object.

    List<Integer> mutableList = new ArrayList<Integer>();

    mutableList.add(1);
    mutableList.add(2);
    mutableList.add(3);
    mutableList.add(4);
    mutableList.add(5);

    System.out.println(mutableList);

    Collections.shuffle(mutableList);

    System.out.println(mutableList);

    Collections.sort(mutableList);

    System.out.println(mutableList);

Output of this code:

run:
[1, 2, 3, 4, 5]
[3, 4, 1, 5, 2]
[1, 2, 3, 4, 5]
BUILD SUCCESSFUL (total time: 0 seconds)

I wrote this javascript script and included it in the header (before anything loads). It seems to work. If the page was loaded more than one hour ago or the situation is undefined it will reload everything from server. The time of one hour = 3600000 milliseconds can be changed in the following line: if(alter > 3600000)

If there are no spaces in paths, and you are interested, like I was, in files of specific extension only, you can use

git checkout otherBranch -- $(git ls-tree --name-only -r otherBranch | egrep '*.java')

Incase any one still wondering how to add environment variables then please use this link to add variables. Link: https://sqlbackupandftp.com/blog/setting-windows-path-for-postgres-tools

if (strpos($string, $word) === FALSE) {
   ... not found ...
}

Note that strpos() is case sensitive, if you want a case-insensitive search, use stripos() instead.

Also note the ===, forcing a strict equality test. strpos CAN return a valid 0 if the 'needle' string is at the start of the 'haystack'. By forcing a check for an actual boolean false (aka 0), you eliminate that false positive.

Summarized

Adding:

android:layout_centerInParent="true"

just works on RelativeLayout, if one of the following attributes is also set for the view:

android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"

which alignes the child view to the parent view. The "center" is based on the axis of the alignement you have chosen:

left/right -> vertical

top/bottom -> horizontal

Setting the gravity of childs/content inside the view:

android:gravity="center"

is centering the child inside the parent view in any case, if there is no alignment set. Optional you can choose:

<!-- Axis to Center -->
android:gravity="center_horizontal"
android:gravity="center_vertical"

<!-- Alignment to set-->
android:gravity="top"
android:gravity="bottom"
android:gravity="left"
android:gravity="right"
android:gravity="fill"
...

Then there is:

android:layout_gravity="center"

which is centering the view itself inside it's parent

And at last you can add the following attribute to the parents view:

android:layout_centerHorizontal="true"
android:layout_centerVertical="true"

We have come with a great solution. This solution is practically done in Laravel 6. If you want to remove any package from your Laravel Project then you can easily remove the package by following below steps:

Step 1: You must know the package name which you want to remove. If you don't know complete package name then you can open your project folder and go to composer.json file and check name in require an array

"require": {
        "php": "^7.2",
        "fideloper/proxy": "^4.0",
        "laravel/framework": "^6.2",
        "laravel/passport": "^8.3",
        "laravel/tinker": "^2.0"
    },

Suppose, here I am going to remove "fideloper/proxy" package.

Step 2: Open command prompt with your project root folder directory Step 3: First of all clear all cache by following commands. Run commands one by one.

php artisan cache:clear  
php artisan config:clear 

Step 4: Now write the following command to remove the package. Here you need to change your package name instead of my example package.

composer remove fideloper/proxy

Now, wait for a few seconds your package is removing.

You could wrap the textbox and button in an ASP:Panel, and set the DefaultButton property of the Panel to the Id of your Submit button.

<asp:Panel ID="Panel1" runat="server" DefaultButton="SubmitButton">
    <asp:TextBox ID="TextBox1" runat="server" />
    <asp:Button ID="SubmitButton" runat="server" Text="Submit" OnClick="SubmitButton_Click" />
</asp:Panel>

Now anytime the focus is within the Panel, the 'SubmitButton_Click' event will fire when enter is pressed.

For linux in case; you can use wget command

import os
url1 = 'YOUR_URL_WHATEVER'
os.system('wget {}'.format(url1))

First you need to activate your environment .

pip install ipykernel

Next you can add your virtual environment to Jupyter by typing:

python -m ipykernel install --name = my_env

Note that if you have a generic interface IMyInterface<T> then this will always return false:

  typeof(IMyInterface<>).IsAssignableFrom(typeof(MyType)) /* ALWAYS FALSE */

This doesn't work either:

  typeof(MyType).GetInterfaces().Contains(typeof(IMyInterface<>))  /* ALWAYS FALSE */

However, if MyType implements IMyInterface<MyType> this works and returns true:

  typeof(IMyInterface<MyType>).IsAssignableFrom(typeof(MyType))

However, you likely will not know the type parameter T at runtime. A somewhat hacky solution is:

  typeof(MyType).GetInterfaces()
                .Any(x=>x.Name == typeof(IMyInterface<>).Name)

Jeff's solution is a bit less hacky:

  typeof(MyType).GetInterfaces()
         .Any(i => i.IsGenericType 
             && i.GetGenericTypeDefinition() == typeof(IMyInterface<>));

Here's a extension method on Type that works for any case:

public static class TypeExtensions
{
    public static bool IsImplementing(this Type type, Type someInterface)
    {
        return type.GetInterfaces()
             .Any(i => i == someInterface 
                 || i.IsGenericType 
                    && i.GetGenericTypeDefinition() == someInterface);
    }
}

(Note that the above uses linq, which is probably slower than a loop.)

You can then do:

   typeof(MyType).IsImplementing(IMyInterface<>)

I have gone through the same problem when I was using

    myApp.controller('mainController', ['$scope', function($scope,) {
        //$http was not working in this
    }]);

I have changed the above code to given below. Remember to include $http(2 times) as given below.

 myApp.controller('mainController', ['$scope','$http', function($scope,$http) {
      //$http is working in this
 }]);

and It has worked well.

They're completely different. Objective C has more in common with Smalltalk than with C++ (well, except for the syntax, really).

Using python 3 and opencv-python version 4.4.0, the following code should work:

img_src = cv2.imread('image.png')
img_clone = img_src.copy()

That doesn't work because, judging by the rest of the code, the initial value of the text input is "Default text" - which is more than one character, and so your if condition is always true.

The simplest way to make it work, it seems to me, is to account for this case:

    var value = $(this).val();
    if ( value.length > 0 && value != "Default text" ) ...

Here I'm just doing the difference between today, and a CREATED_DATE DATE field in a table, which obviously is a date in the past:

SELECT  
((FLOOR(ABS(MONTHS_BETWEEN(CREATED_DATE, SYSDATE))) / 12) * 12) || ' months, '  AS MONTHS,
-- we take total days - years(as days) - months(as days) to get remaining days
FLOOR((SYSDATE - CREATED_DATE) -      -- total days
(FLOOR((SYSDATE - CREATED_DATE)/365)*12)*(365/12) -      -- years, as days
-- this is total months - years (as months), to get number of months, 
-- then multiplied by 30.416667 to get months as days (and remove it from total days)
FLOOR(((SYSDATE - CREATED_DATE)/365)*12 - (FLOOR((SYSDATE - CREATED_DATE)/365)*12)) * (365/12))
|| ' days ' AS DAYS 
FROM MyTable

I use (365/12), or 30.416667, as my conversion factor because I'm using total days and removing years and months (as days) to get the remainder number of days. It was good enough for my purposes, anyway.

My SQL supports the function of a substring_Index where it will return the postion of a value in a string for the n occurance. A similar User defined function could be written to achieve this. Example in the link

Alternatively you could use charindex function call it x times to report the location of each _ given a starting postion +1 of the previously found instance. until a 0 is found

Edit: NM Charindex is the correct function

Try this:

print cast(getdate() as date )

I was looking for a solution to this problem but without relying on jQuery UI.

This is what I came up with and it works for me (no plugins, just Javascript and jQuery); -- Heres the working fiddle -- http://jsfiddle.net/CriddleCraddle/yYcaY/2/

Set the current CSS parameter in your CSS file as normal css, and create a new class that just handles the parameter to change i.e. background-color, and set it to '!important' to override the default behavior. like this...

.button_flash {
background-color: #8DABFF !important;
}//This is the color to change to.  

Then just use the function below and pass in the DOM element as a string, an integer for the number of times you would want the flash to occur, the class you want to change to, and an integer for delay.

Note: If you pass in an even number for the 'times' variable, you will end up with the class you started with, and if you pass an odd number you will end up with the toggled class. Both are useful for different things. I use the 'i' to change the delay time, or they would all fire at the same time and the effect would be lost.

function flashIt(element, times, klass, delay){
  for (var i=0; i < times; i++){
    setTimeout(function(){
      $(element).toggleClass(klass);
    }, delay + (300 * i));
  };
};

//Then run the following code with either another delay to delay the original start, or
// without another delay.  I have provided both options below.

//without a start delay just call
flashIt('.info_status button', 10, 'button_flash', 500)

//with a start delay just call
setTimeout(function(){
  flashIt('.info_status button', 10, 'button_flash', 500)
}, 4700);
// Just change the 4700 above to your liking for the start delay.  In this case, 
//I need about five seconds before the flash started.  

What is Git:

"Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency"

Git is a distributed peer-peer version control system. Each node in the network is a peer, storing entire repositories which can also act as a multi-node distributed back-ups. There is no specific concept of a central server although nodes can be head-less or 'bare', taking on a role similar to the central server in centralised version control systems.

What is GitHub:

"GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features."

Github provides access control and several collaboration features such as wikis, task management, and bug tracking and feature requests for every project.

You do not need GitHub to use Git.

GitHub (and any other local, remote or hosted system) can all be peers in the same distributed versioned repositories within a single project.

Github allows you to:

• Share your repositories with others.
• Access other user's repositories.
• Store remote copies of your repositories (github servers) as backup of your local copies.

Unlike C, Java allows using the % for both integer and floating point and (unlike C89 and C++) it is well-defined for all inputs (including negatives):

From JLS §15.17.3:

The result of a floating-point remainder operation is determined by the rules of IEEE arithmetic:

• If either operand is NaN, the result is NaN.
• If the result is not NaN, the sign of the result equals the sign of the dividend.
• If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN.
• If the dividend is finite and the divisor is an infinity, the result equals the dividend.
• If the dividend is a zero and the divisor is finite, the result equals the dividend.
• In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the floating-point remainder r from the division of a dividend n by a divisor d is defined by the mathematical relation r=n-(d·q) where q is an integer that is negative only if n/d is negative and positive only if n/d is positive, and whose magnitude is as large as possible without exceeding the magnitude of the true mathematical quotient of n and d.

So for your example, 0.5/0.3 = 1.6... . q has the same sign (positive) as 0.5 (the dividend), and the magnitude is 1 (integer with largest magnitude not exceeding magnitude of 1.6...), and r = 0.5 - (0.3 * 1) = 0.2

Oracle support Mathematical Subtract - operator on Data datatype. You may directly put in select clause following statement:

to_char (s.last_upd – s.created, ‘999999D99')

Check the EXAMPLE for more visibility.

In case you need the output in termes of hours, then the below might help;

Select to_number(substr(numtodsinterval([END_TIME]-[START_TIME]),’day’,2,9))*24 +
to_number(substr(numtodsinterval([END_TIME]-[START_TIME],’day’),12,2))
||':’||to_number(substr(numtodsinterval([END_TIME]-[START_TIME],’day’),15,2)) 
from [TABLE_NAME];

I needed the application URL but with the subdirectory. I used:

root_url(:only_path => false)

This is the most basic version I can think of:

public function implode_key($glue = "", $pieces = array())
{
    $keys = array_keys($pieces);
    return implode($glue, $keys);
}

The correct method for capturing tab selection event is to set a function as the value for the select option when initializing the tabs (you can also set them dynamically afterwards), like so:

$('#tabs, #fragment-1').tabs({
  select: function(event, ui){
    // Do stuff here
  }
});

You can see the actual code in action here: http://jsfiddle.net/mZLDk/

Edit: With the link you gave me, I've created a test environment for jQuery 1.2.3 with jQuery UI 1.5 (I think?). Some things obviously changed from then. There wasn't a separate ui object which was separated from the original event object. The code looks something like this:

// Tab initialization
$('#container ul').tabs({
    select: function(event) {
        // You need Firebug or the developer tools on your browser open to see these
        console.log(event);
        // This will get you the index of the tab you selected
        console.log(event.options.selected);
        // And this will get you it's name
        console.log(event.tab.text);
    }
});

Phew. If there's anything to learn here, it's that supporting legacy code is hard. See the jsfiddle for more: http://jsfiddle.net/qCfnL/1/

Edit: For those who is using newer version of jQuery, try the following:

$("#tabs").tabs({
    activate: function (event, ui) {
        console.log(event);
    }
});

Include path of jar (jdbc driver) in classpath.

It's quite possible that someone will provide a truly detailed answer here, but I've always found this post from Robert Sosinski to be a great explanation of the subtleties between blocks, procs & lambdas.

I should add that I believe the post I'm linking to is specific to ruby 1.8. Some things have changed in ruby 1.9, such as block variables being local to the block. In 1.8, you'd get something like the following:

>> a = "Hello"
=> "Hello"
>> 1.times { |a| a = "Goodbye" }
=> 1
>> a
=> "Goodbye"

Whereas 1.9 would give you:

>> a = "Hello"
=> "Hello"
>> 1.times { |a| a = "Goodbye" }
=> 1
>> a
=> "Hello"

I don't have 1.9 on this machine so the above might have an error in it.

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

show global variables where variable_name like 'character_set_%' or variable_name like 'collation%'

I needed time only up to one day, 24h, this was my take:

const milliseconds = 5680000;_x000D_
_x000D_
const hours = `0${new Date(milliseconds).getHours() - 1}`.slice(-2);_x000D_
const minutes = `0${new Date(milliseconds).getMinutes()}`.slice(-2);_x000D_
const seconds = `0${new Date(milliseconds).getSeconds()}`.slice(-2);_x000D_
_x000D_
const time = `${hours}:${minutes}:${seconds}`_x000D_
console.log(time);

you could get days this way as well if needed.

From Christoffer Noring, Pablo Deeleman's book “Learning Angular - Second Edition”:

"As our applications grow and evolves, each one of our code entities will internally require instances of other objects, which are better known as dependencies in the world of software engineering. The action of passing such dependencies to the dependent client is known as injection, and it also entails the participation of another code entity, named the injector. The injector will take responsibility for instantiating and bootstrapping the required dependencies so they are ready for use from the very moment they are successfully injected in the client. This is very important since the client knows nothing about how to instantiate its own dependencies and is only aware of the interface they implement in order to use them."

From: Anton Moiseev. book “Angular Development with Typescript, Second Edition.”:

“In short, DI helps you write code in a loosely coupled way and makes your code more testable and reusable.”

Tried printf(1)?

printf "%x\n" 34

There are probably ways of doing that with builtin functions in all shells but it would be less portable. I've not checked the POSIX sh specs to see whether it has such capabilities.

Just come across this recently, method 3 and 4 are not appropriate because how the strings are copied and then put together. For a small program this problem is insignificant, but for any real web application this action where we have to deal with frequency string manipulations can affects the performance and readability.

While there are IPv6 equivalents for the IPv4 address range, you can't convert all IPv6 addresses to IPv4 - there are more IPv6 addresses than there are IPv4 addresses.

The only sane way around this issue is to update your application to be able to understand and store IPv6 addresses.

step 1: add

<asp:FileUpload runat="server" id="fileUpload1" Multiple="Multiple">

    Dim ImageFiles As HttpFileCollection = Request.Files
    For i As Integer = 0 To ImageFiles.Count - 1

There are two type of paths: absolute and relative. This is basically the same for files in your hard disc and directories in a URL.

Absolute paths start with a leading slash. They always point to the same location, no matter where you use them:

• /pages/en/faqs/faq-page1.html

Relative paths are the rest (all that do not start with slash). The location they point to depends on where you are using them

• index.html is:
  • /pages/en/faqs/index.html if called from /pages/en/faqs/faq-page1.html
  • /pages/index.html if called from /pages/example.html
  • etc.

There are also two special directory names: . and ..:

• . means "current directory"
• .. means "parent directory"

You can use them to build relative paths:

• ../index.html is /pages/en/index.html if called from /pages/en/faqs/faq-page1.html
• ../../index.html is /pages/index.html if called from /pages/en/faqs/faq-page1.html

Once you're familiar with the terms, it's easy to understand what it's failing and how to fix it. You have two options:

• Use absolute paths
• Fix your relative paths

You can work around this by setting the X-UA-Compatible meta header for the specific version of IE you are debugging with. This will change the Browser Mode to the version you specify in the header.

For example:

<meta http-equiv="X-UA-Compatible" content="IE=9" />

In order for the Browser Mode to update on the Developer Tools, you must close [the Developer Tools] and reopen again. This will switch to that specific version.

Switching from a minor version to a greater version will work just fine by refreshing, but if you want to switch back from a greater version to a minor version, such as from 9 to 7, you would need to open a new tab and load the page again.

Here's a screenshot:

@Amit: SortedMap is an interface whereas TreeMap is a class which implements the SortedMap interface. That means if follows the protocol which SortedMap asks its implementers to do. A tree unless implemented as search tree, can't give you ordered data because tree can be any kind of tree. So to make TreeMap work like Sorted order, it implements SortedMap ( e.g, Binary Search Tree - BST, balanced BST like AVL and R-B Tree , even Ternary Search Tree - mostly used for iterative searches in ordered way ).

public class TreeMap<K,V>
extends AbstractMap<K,V>
implements SortedMap<K,V>, Cloneable, Serializable

In NUT-SHELL HashMap : gives data in O(1) , no ordering

TreeMap : gives data in O(log N), base 2. with ordered keys

LinkedHashMap : is Hash table with linked list (think of indexed-SkipList) capability to store data in the way it gets inserted in the tree. Best suited to implement LRU ( least recently used ).

If you need to display your variable unescaped, use this format:

<script th:inline="javascript">
/*<![CDATA[*/

    var message = /*[(${message})]*/ 'default';

/*]]>*/
</script>

Note the [( brackets which wrap the variable.

Do you have a Python virtual environment that you need to enter before you run manage.py?

I ran into this error myself, and that was the problem.

event.key === "Backspace"

More recent and much cleaner: use event.key. No more arbitrary number codes!

note.addEventListener('keydown', function(event) {
    const key = event.key; // const {key} = event; ES6+
    if (key === "Backspace") {
        // Do something
    }

I know this is an old question, but I shall post my answer for posterity...

It depends on the system that you are building and the particular business rules in place.

I am building a moderate to large scale CRM in MongoDb, C# (Backend API), and Angular (Frontend web app) and found ObjectId utterly terrible for use in Angular Routing for selecting particular entities. Same with API Controller routing.

The suggestion above worked perfectly for my project.

db.contacts.insert({
 "id":db.contacts.find().Count()+1,
 "name":"John Doe",
 "emails":[
    "[email protected]",
    "[email protected]"
 ],
 "phone":"555111322",
 "status":"Active"
});

The reason it is perfect for my case, but not all cases is that as the above comment states, if you delete 3 records from the collection, you will get collisions.

My business rules state that due to our in house SLA's, we are not allowed to delete correspondence data or clients records for longer than the potential lifespan of the application I'm writing, and therefor, I simply mark records with an enum "Status" which is either "Active" or "Deleted". You can delete something from the UI, and it will say "Contact has been deleted" but all the application has done is change the status of the contact to "Deleted" and when the app calls the respository for a list of contacts, I filter out deleted records before pushing the data to the client app.

Therefore, db.collection.find().count() + 1 is a perfect solution for me...

It won't work for everyone, but if you will not be deleting data, it works fine.

I would suggest:

DECLARE @sqlStatement nvarchar(MAX),
        @tableName nvarchar(50) = 'TripEvent',
        @columnName nvarchar(50) = 'CreatedDate';

SELECT                  @sqlStatement = 'ALTER TABLE ' + @tableName + ' DROP CONSTRAINT ' + dc.name + ';'
        FROM            sys.default_constraints AS dc
            LEFT JOIN   sys.columns AS sc
                ON      (dc.parent_column_id = sc.column_id)
        WHERE           dc.parent_object_id = OBJECT_ID(@tableName)
        AND         type_desc = 'DEFAULT_CONSTRAINT'
        AND         sc.name = @columnName
PRINT'   ['+@tableName+']:'+@@SERVERNAME+'.'+DB_NAME()+'@'+CONVERT(VarChar, GETDATE(), 127)+';  '+@sqlStatement;
IF(LEN(@sqlStatement)>0)EXEC sp_executesql @sqlStatement

Byte[] Content = new BinaryReader(file.InputStream).ReadBytes(file.ContentLength);

I'm against using when others so I would use (returning an "boolean integer" due to SQL not suppporting booleans)

create or replace function is_number(param in varchar2) return integer
 is
   ret number;
 begin
    ret := to_number(param);
    return 1; --true
 exception
    when invalid_number then return 0;
 end;

In the SQL call you would use something like

select case when ( is_number(myTable.id)=1 and (myTable.id >'0') ) 
            then 'Is a number greater than 0' 
            else 'it is not a number or is not greater than 0' 
       end as valuetype  
  from table myTable

you can use requestAnimationFrame() function like in the below,

function unlimited () {
    requestAnimationFrame(unlimited);
    console.log("arian")
}

unlimited();

Say, you want to sort by 'created_on' field, then you can do like this,

.sort('{}'.format('created_on'), 1 if sort_type == 'asc' else -1)

Since I've visited this page several times, I've decided to post an example (loose) comparison test.

Results:

""        -> false
"0"       -> false

"01"      -> true
"abc"     -> true
"true"    -> true
"false"   -> true
0         -> false
0.1       -> true
1         -> true
1.1       -> true
-42       -> true
"NAN"     -> true
0         -> false
          -> true
null      -> false
true      -> true
false     -> false
[]        -> false
["a"]     -> true
{}        -> true
{}        -> true
{"s":"f"} -> true

Code:

class Vegetable {}

class Fruit {
    public $s = "f";
}

$cases = [
    "",
    "0",
    "1",
    "01",
    "abc",
    "true",
    "false",
    0,
    0.1,
    1,
    1.1,
    -42,
    "NAN",
    (float) "NAN",
    NAN,
    null,
    true,
    false,
    [],
    ["a"],
    new stdClass(),
    new Vegetable(),
    new Fruit(),
];

echo "<pre>" . PHP_EOL;

foreach ($cases as $case) {
    printf("%s -> %s" . PHP_EOL, str_pad(json_encode($case), 9, " ", STR_PAD_RIGHT), json_encode( $case == true ));
}

When a strict (===) comparison is done, everything except true returns false.

Setting the image using picture.ImageLocation() works fine, but you are using a relative path. Check your path against the location of the .exe after it is built.

For example, if your .exe is located at:

<project folder>/bin/Debug/app.exe

The image would have to be at:

<project folder>/bin/Image/1.jpg

Of course, you could just set the image at design-time (the Image property on the PictureBox property sheet).

If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory to Copy if newer.

At this point the image file will be copied when you build the application and you can use

picture.ImageLocation = @"Image\1.jpg"; 

df = pd.DataFrame(scale.fit_transform(df.values), columns=df.columns, index=df.index)

This should work without depreciation warnings.

All you should need to do is:

# if the file in the right place isn't already committed:
git add <path to desired file>

# remove the "both deleted" file from the index:
git rm --cached ../public/images/originals/dog.ai

# commit the merge:
git commit

you can store your array using group_Concat like that

 INSERT into Table1 (fruits)  (SELECT GROUP_CONCAT(fruit_name) from table2)
 WHERE ..... //your clause here

HERE an example in fiddle

The user-agent should be specified as a field in the header.

Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent.

If you're using requests v2.13 and newer

The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:

import requests

url = 'SOME URL'

headers = {
    'User-Agent': 'My User Agent 1.0',
    'From': '[email protected]'  # This is another valid field
}

response = requests.get(url, headers=headers)

If you're using requests v2.12.x and older

Older versions of requests clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.

import requests

url = 'SOME URL'

# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()

# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
    {
        'User-Agent': 'My User Agent 1.0',
    }
)

response = requests.get(url, headers=headers)

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

IF EXISTS will basically do a SELECT - the same one that UPDATE would.

As such, it will decrease performance - if there's nothing to update, you did the same amount of work (UPDATE would have queried same lack of rows as your select) and if there's something to update, you juet did an un-needed select.

Just this:

// assuming "cloud" is:
// int cloud[10]; 
// or any other fixed size

#define countof(x) (sizeof(x)/sizeof((x)[0]))

int* pMax = std::max_element(cloud, cloud + countof(cloud));

I think you're getting confused about what can hold what in JSON.Net.

• A JToken is a generic representation of a JSON value of any kind. It could be a string, object, array, property, etc.
• A JProperty is a single JToken value paired with a name. It can only be added to a JObject, and its value cannot be another JProperty.
• A JObject is a collection of JProperties. It cannot hold any other kind of JToken directly.

In your code, you are attempting to add a JObject (the one containing the "banana" data) to a JProperty ("orange") which already has a value (a JObject containing {"colour":"orange","size":"large"}). As you saw, this will result in an error.

What you really want to do is add a JProperty called "banana" to the JObject which contains the other fruit JProperties. Here is the revised code:

JObject foodJsonObj = JObject.Parse(jsonText);
JObject fruits = foodJsonObj["food"]["fruit"] as JObject;
fruits.Add("banana", JObject.Parse(@"{""colour"":""yellow"",""size"":""medium""}"));

Extending a class doesn't mean that you are instantiating the class. Actually, in your case you are creating an instance of the subclass.

I am pretty sure that abstract classes do not allow initiating. So, I'd say no: you can't instantiate an abstract class. But, you can extend it / inherit it.

You can't directly instantiate an abstract class. But it doesn't mean that you can't get an instance of class (not actully an instance of original abstract class) indirectly. I mean you can not instantiate the orginial abstract class, but you can:

1. Create an empty class
2. Inherit it from abstract class
3. Instantiate the dervied class

So you get access to all the methods and properties in an abstract class via the derived class instance.

uri = URI('https://myapp.com/api/v1/resource')
req = Net::HTTP::Post.new(uri, 'Content-Type' => 'application/json')
req.body = {param1: 'some value', param2: 'some other value'}.to_json
res = Net::HTTP.start(uri.hostname, uri.port) do |http|
  http.request(req)
end

Change the definition of multiply to take additional unknown arguments:

multiply <- function(a, b, ...) {
  # Original code
}

My favourite is Open3

  require "open3"

  Open3.popen3('nroff -man') { |stdin, stdout, stderr| ... }

df = pd.DataFrame({'one' : pd.Series([1., 1, 1, 3]), 'two' : pd.Series([1., 2., 1, 3] ), 'three' : pd.Series([1., 2., 1, 2] )})
df['str_list'] = df.apply(lambda row: ' '.join([str(int(val)) for val in row]), axis=1)
df1 = pd.DataFrame(df['str_list'].value_counts().values, index=df['str_list'].value_counts().index, columns=['Count'])

Produces:

>>> df1
       Count
1 1 1      2
3 2 3      1
1 2 2      1

If the index values must be a list, you could take the above code a step further with:

df1.index = df1.index.str.split()

Produces:

           Count
[1, 1, 1]      2
[3, 2, 3]      1
[1, 2, 2]      1

Use html2text (example HTML to text), licensed under the Eclipse Public License. It uses PHP's DOM methods to load from HTML, and then iterates over the resulting DOM to extract plain text. Usage:

// when installed using the Composer package
$text = Html2Text\Html2Text::convert($html);

// usage when installed using html2text.php
require('html2text.php');
$text = convert_html_to_text($html);

Although incomplete, it is open source and contributions are welcome.

Issues with other conversion scripts:

• Since html2text (GPL) is not EPL-compatible.
• lkessler's link (attribution) is incompatible with most open source licenses.

The easiest way would probably be to put your web resources into the assets folder then call:

webView.loadUrl("file:///android_asset/filename.html");

For Complete Communication between Java and Webview See This

Update: The assets folder is usually the following folder: <project>/src/main/assets This can be changed in the asset folder configuration setting in your <app>.iml file as:

<option name=”ASSETS_FOLDER_RELATIVE_PATH” value=”/src/main/assets” /> See Article Where to place the assets folder in Android Studio

In my situation,I use storyboard to organize my view controllers.I want to change all status bar style.

You can see in picture below.

Stars View Controller is a CPBaseNavigationController,and CPBaseNavigationController is subclass of UINavigationController.

I try doing the next setps:

1. In AppDelegate.swift func didFinishLaunchingWithOptions,add

   //change status bar color
   UIApplication.sharedApplication().statusBarHidden = false
   UIApplication.sharedApplication().statusBarStyle = .LightContent
   

   but no effect.

2. In StoryBoard,find the Base Tab BarController(picture on the above).select Attributes Inspector, change the Sattus Bar attribute to Light Content.so bad,no effect.

3. Last I get it.In my custom navigation controller CPBaseNavigationController,add func preferredStatusBarStyle

   override func preferredStatusBarStyle() -> UIStatusBarStyle {
      return .LightContent
   }
   

   It works well!

Besides,statusBarStyle deprecated in 9.0,you can use -[UIViewController preferredStatusBarStyle].

I have the same issue, one of our team members gives me a solution. To allowed the div fix position and relative to other div, our solution is to use a father container wrap the fix div and scroll div.

<div class="container">
  <div class="scroll"></div>
  <div class="fix"></div>
</div>

css

.container {
  position: relative;
  flex:1;
  display:flex;
}

.fix {
  prosition:absolute;
}

This is an old question, but since it still comes up at the top of my results in Google, here's another way.

import pandas as pd
import numpy as np

df = pd.DataFrame({'col1':list("abc"),'col2':range(3)},index = range(3))

Say you want to replicate the rows where col1="b".

reps = [3 if val=="b" else 1 for val in df.col1]
df.loc[np.repeat(df.index.values, reps)]

You could replace the 3 if val=="b" else 1 in the list interpretation with another function that could return 3 if val=="b" or 4 if val=="c" and so on, so it's pretty flexible.

Others have already explained this well. Let me give you an animation which will explain this quickly: http://codepen.io/chriscoyier/pen/lotjh

Here is some code for you to play with and learn the concepts.

HTML:

<html>
  <body>
    <div id="border-demo">
    </div>
  </body>
</html>

CSS:

/*border-width is border thickness*/
#border-demo {
    background: gray;
    border-color: yellow blue red green;/*top right bottom left*/
    border-style: solid;
    border-width: 25px 25px 25px 25px;/*top right bottom left*/
    height: 50px;
    width: 50px;
}

Play with this and see what happens. Set height and width to zero. Then remove top border and make left and right transparent, or just look at the code below to make a css triangle:

#border-demo {
    border-left: 50px solid transparent;
    border-right: 50px solid transparent;
    border-bottom: 100px solid blue;
}

For React you must use it's per-define keywords to define html attributes.

class -> className

is used and

for -> htmlFor

is used, as react is case sensitive make sure you must follow small and capital as required.

For weeks, you can use function difftime:

date1 <- strptime("14.01.2013", format="%d.%m.%Y")
date2 <- strptime("26.03.2014", format="%d.%m.%Y")
difftime(date2,date1,units="weeks")
Time difference of 62.28571 weeks

But difftime doesn't work with duration over weeks.
The following is a very suboptimal solution using cut.POSIXt for those durations but you can work around it:

seq1 <- seq(date1,date2, by="days")
nlevels(cut(seq1,"months"))
15
nlevels(cut(seq1,"quarters"))
5
nlevels(cut(seq1,"years"))
2

This is however the number of months, quarters or years spanned by your time interval and not the duration of your time interval expressed in months, quarters, years (since those do not have a constant duration). Considering the comment you made on @SvenHohenstein answer I would think you can use nlevels(cut(seq1,"months")) - 1 for what you're trying to achieve.

It works with Android Studio 1.2 + OpenCV-2.4.11-android-sdk (.zip), too.

Just do the following:

1) Follow the answer that starts with "You can do this very easily in Android Studio. Follow the steps below to add OpenCV in your project as library." by TGMCians.

2) Modify in the <yourAppDir>\libraries\opencv folder your newly created build.gradle to (step 4 in TGMCians' answer, adapted to OpenCV2.4.11-android-sdk and using gradle 1.1.0):

apply plugin: 'android-library'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 21
        versionCode 2411
        versionName "2.4.11"
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
            aidl.srcDirs = ['src']
        }
    }
}

3) *.so files that are located in the directories "armeabi", "armeabi-v7a", "mips", "x86" can be found under (default OpenCV-location): ..\OpenCV-2.4.11-android-sdk\OpenCV-android-sdk\sdk\native\libs (step 9 in TGMCians' answer).

Enjoy and if this helped, please give a positive reputation. I need 50 to answer directly to answers (19 left) :)

In VS 2010 just right click on project or on reference and click add reference. On the popup window Select Assemblies - > Extensions -> System.Web.Helpers

I just hit this after doing a fresh install of DOCKER from the main docs. The problem for me was that immediately after the install, the service is not running.

These commands will help you to make sure docker is up and running for your run command to find it:

$ sudo service --status-all 
$ sudo service docker start
$ sudo service docker start

The whole point of HttpOnly cookies is that they can't be accessed by JavaScript.

The only way (except for exploiting browser bugs) for your script to read them is to have a cooperating script on the server that will read the cookie value and echo it back as part of the response content. But if you can and would do that, why use HttpOnly cookies in the first place?

For horizontal alignment (No CSS)

Just insert an align attribute inside the table tag

<table align="center"></table

I also have the problem but now solved

$cfg['Servers'][$i]['user'] = 'admin'; - I change the user name from 'root' to 'admin'

fish starts by executing commands in ~/.config/fish/config.fish. You can create it if it does not exist:

vim ~/.config/fish/config.fish

and save it with :wq

step1. make configuration file (like .bashrc)

config.fish

step2. just write your alias like this;

alias rm="rm -i"

You can create the PDF document using PdfSharp. It is an open source .NET library.

When trying to print the document it get worse. I have looked allover for a open source way of doing it. There are some ways do do it using AcroRd32.exe but it all depends on the version, and it cannot be done without acrobat reader staying open.

I finally ended up using VintaSoftImaging.NET SDK. It costs some money but is much cheaper than the alternative and it solves the problem really easy.

var doc = new Vintasoft.Imaging.Print.ImagePrintDocument { DocumentName = @"C:\Test.pdf" };
doc.Print();

That just prints to the default printer without showing. There are several alternatives and options.

Update for 2018:

Now there's no need for jQuery and it's been a while since document.querySelector or document.querySelectorAll (for multiple elements) do almost exactly same job as $, plus more explicit ones getElementById, getElementsByClassName, getElementsByTagName

Disabling one field of "input-checkbox" class

document.querySelector('.input-checkbox').disabled = true;

or multiple elements

document.querySelectorAll('.input-checkbox').forEach(el => el.disabled = true);

You can also use npm for this by adding an entry to the scripts element of your package.json file. E.g.

"launch-ios": "react-native run-ios --simulator \"iPad Air 2\""

Then to use this: npm run launch-ios

Hey so I stumbled upon this and got it working, here is how:

inside my component.html

<mat-paginator #paginator [pageSize]="pageSize" [pageSizeOptions]="[5, 10, 20]" [showFirstLastButtons]="true" [length]="totalSize"
    [pageIndex]="currentPage" (page)="pageEvent = handlePage($event)">
</mat-paginator>

Inside my component.ts

public array: any;
public displayedColumns = ['', '', '', '', ''];
public dataSource: any;    

public pageSize = 10;
public currentPage = 0;
public totalSize = 0;

@ViewChild(MatPaginator) paginator: MatPaginator;

constructor(private app: AppService) { }

ngOnInit() {
  this.getArray();
}

public handlePage(e: any) {
  this.currentPage = e.pageIndex;
  this.pageSize = e.pageSize;
  this.iterator();
}

private getArray() {
  this.app.getDeliveries()
    .subscribe((response) => {
      this.dataSource = new MatTableDataSource<Element>(response);
      this.dataSource.paginator = this.paginator;
      this.array = response;
      this.totalSize = this.array.length;
      this.iterator();
    });
}

private iterator() {
  const end = (this.currentPage + 1) * this.pageSize;
  const start = this.currentPage * this.pageSize;
  const part = this.array.slice(start, end);
  this.dataSource = part;
}

All the paging work is done from within the iterator method. This method works out the skip and take and assigns that to the dataSource for the Material table.

first of all, try to give the format you want to the current date time of your server:

1. Obtain current date time

   $current_date = getdate();

2. Separate date and time to manage them as you wish:

$current_date_only = $current_date[year].'-'.$current_date[mon].'-'.$current_date[mday]; $current_time_only = $current_date['hours'].':'.$current_date['minutes'].':'.$current_date['seconds'];

3. Compare it depending if you are using donly date or datetime in your DB:

   $today = $current_date_only.' '.$current_time_only;

   or

   $today = $current_date_only;

   if($today < $expireDate)

hope it helps

The fast way to get the content of a directory using Java 7 NIO :

import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.FileSystems;
import java.nio.file.Path;

...

Path dir = FileSystems.getDefault().getPath( filePath );
DirectoryStream<Path> stream = Files.newDirectoryStream( dir );
for (Path path : stream) {
   System.out.println( path.getFileName() );
}
stream.close();

first,use git pull to merge repository save your change.then retype git commit -m "your commit".

I believe you are looking for the query functions, isBefore, isSame, and isAfter.

But it's a bit difficult to tell exactly what you're attempting. Perhaps you are just looking to get the difference between the input time and the current time? If so, consider the difference function, diff. For example:

moment().diff(date_time, 'minutes')

A few other things:

• There's an error in the first line:

    var date_time = 2013-03-24 + 'T' + 10:15:20:12 + 'Z'
  

  That's not going to work. I think you meant:

    var date_time = '2013-03-24' + 'T' + '10:15:20:12' + 'Z';
  

  Of course, you might as well:

    var date_time = '2013-03-24T10:15:20:12Z';
  

• You're using: .tz('UTC') incorrectly. .tz belongs to moment-timezone. You don't need to use that unless you're working with other time zones, like America/Los_Angeles.

  If you want to parse a value as UTC, then use:

    moment.utc(theStringToParse)
  

  Or, if you want to parse a local value and convert it to UTC, then use:

    moment(theStringToParse).utc()
  

  Or perhaps you don't need it at all. Just because the input value is in UTC, doesn't mean you have to work in UTC throughout your function.

• You seem to be getting the "now" instance by moment(new Date()). You can instead just use moment().

Updated

Based on your edit, I think you can just do this:

var date_time = req.body.date + 'T' + req.body.time + 'Z';
var isafter = moment(date_time).isAfter('2014-03-24T01:14:00Z');

Or, if you would like to ensure that your fields are validated to be in the correct format:

var m = moment.utc(req.body.date + ' ' + req.body.time, "YYYY-MM-DD  HH:mm:ss");
var isvalid = m.isValid();
var isafter = m.isAfter('2014-03-24T01:14:00Z');

Also I use Tomcat GUI app (in my case: C:\tomcat\bin\Tomcat9w.bin).

• Go to Java tab:

  

• Set your Java properties, for example:

  Java virtual machine

  C:\Program Files\Java\jre-10.0.2\bin\server\jvm.dll

  Java virtual machine

  C:\tomcat\bin\bootstrap.jar;C:\tomcat\bin\tomcat-juli.jar

  Java Options:

  -Dcatalina.base=C:\tomcat

  -Djava.io.tmpdir=C:\tomcat\temp

  -Djava.util.logging.config.file=C:\tomcat\conf\logging.properties

  -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:8000

  Java 9 options:

  --add-opens=java.base/java.lang=ALL-UNNAMED

  --add-opens=java.base/java.io=ALL-UNNAMED

  --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED

UPDATED:

Correctly calculate a timespan in SQL Server, even if more than 24 hours:

-- Setup test data
declare @minDate datetime = '2012-12-12 20:16:47.160'
declare @maxDate datetime = '2012-12-13 15:10:12.050'

-- Get timespan in hh:mi:ss
select cast(
        (cast(cast(@maxDate as float) - cast(@minDate as float) as int) * 24) /* hours over 24 */
        + datepart(hh, @maxDate - @minDate) /* hours */
        as varchar(10))
    + ':' + right('0' + cast(datepart(mi, @maxDate - @minDate) as varchar(2)), 2) /* minutes */
    + ':' + right('0' + cast(datepart(ss, @maxDate - @minDate) as varchar(2)), 2) /* seconds */

-- Returns 18:53:24

Edge cases that show inaccuracy are especially welcome!

Based on a general research and understanding, "Almost" Everything that can be accessed via a browser is actually called a "Web application" now these days. Even your internet router at home is a web application that uses the HTTP protocol to access the application (i.e the one that "interacts" with you). Yes, there are lots of websites that do "Nothing" except showing you stuff. But the age we are living in, everything operates on the basis of web application. Natwest PLC bank has got a website where you can go and find out things that natwest offer as a consumer/high-street bank. However:

1) You can create your online banking account - Web application 2) View, amend details on your personal stuff - web application 3) Manage money - Web application 4) Deal shares/stocks - Web application

Another good example is Fidelity.com (as quoted in many other examples on the web).

I'm going to have to argue and say that there are two answers:

1) If your purpose is simply to inform your audience with some contents that will never demand any interaction whatsoever, website is your answer. Then it is not a web application.

2) If you are living in the current/modern world i.e. will have a personal site, allow people to see some/all/none of your special stuff, protect yourself from people/bots/etc., web application and websites are no different.

For some applications you can use Fraction instead of floating-point numbers.

>>> from fractions import Fraction
>>> Fraction(1, 3**54)
Fraction(1, 58149737003040059690390169)

(For other applications, there's decimal, as suggested out by the other responses.)

From Cocoa_(API) Wikipedia:

(emphasis added)

Cocoa classes begin with the acronym "NS" (standing either for the NeXT-Sun creation of OpenStep, or for the original proprietary term for the OpenStep framework, NeXTSTEP): NSString, NSArray, etc.

Foundation Kit, or more commonly simply Foundation, first appeared in OpenStep. On Mac OS X, it is based on Core Foundation. Foundation is a generic object-oriented library providing string and value manipulation, containers and iteration, distributed computing, run loops, and other functions that are not directly tied to the graphical user interface. The "NS" prefix, used for all classes and constants in the framework, comes from Cocoa's OPENSTEP heritage, which was jointly developed by NeXT and Sun.

With the helpful advice from people who have answered here I started digging into One-Jar. After some dead-ends (and some results that were exactly like my previous results I managed to get it working. For other peoples reference I'm listing the build.xml that worked for me.

I hope someone else can benefit from this.

You can use sudo ip link delete to remove the interface.

Instead of JSONObject , you can use ObjectMapper to convert java object to json string

ObjectMapper mapper = new ObjectMapper();
String requestBean = mapper.writeValueAsString(yourObject);

Simple: enum names into a List:

List<String> NameList = Enum.GetNames(typeof(YourEnumName)).Cast<string>().ToList()

You can directly use (String)session.getAttribute("username"); inside scriptlet tag ie <% %>.

In case if anyone wants to grab only the Time from a ISO Date, following will be helpful. I was searching for that and I couldn't find a question for it. So in case some one sees will be helpful.

let isoDate = '2020-09-28T15:27:15+05:30';
let result = isoDate.match(/\d\d:\d\d/);
console.log(result[0]);

The output will be the only the time from isoDate which is,

15:27

Below code works fine before 18 API :-

public String getRealPathFromURI(Uri contentUri) {

        // can post image
        String [] proj={MediaStore.Images.Media.DATA};
        Cursor cursor = managedQuery( contentUri,
                        proj, // Which columns to return
                        null,       // WHERE clause; which rows to return (all rows)
                        null,       // WHERE clause selection arguments (none)
                        null); // Order-by clause (ascending by name)
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();

        return cursor.getString(column_index);
}

What you need, according to your comments, is a 'BLOB' (Binary Large OBject) for both image and resume.

to access database from remote machine , you need to give grant all privileges to you data base.

run the following script to give permissions: GRANT ALL PRIVILEGES ON . TO user@'%' IDENTIFIED BY 'password';

First, since length always returns a non-negative number,

if ( length $name )

and

if ( length $name > 0 )

are equivalent.

If you are OK with replacing an undefined value with an empty string, you can use Perl 5.10's //= operator which assigns the RHS to the LHS unless the LHS is defined:

#!/usr/bin/perl

use feature qw( say );
use strict; use warnings;

my $name;

say 'nonempty' if length($name //= '');
say "'$name'";

Note the absence of warnings about an uninitialized variable as $name is assigned the empty string if it is undefined.

However, if you do not want to depend on 5.10 being installed, use the functions provided by Scalar::MoreUtils. For example, the above can be written as:

#!/usr/bin/perl

use strict; use warnings;

use Scalar::MoreUtils qw( define );

my $name;

print "nonempty\n" if length($name = define $name);
print "'$name'\n";

If you don't want to clobber $name, use default.

On Windows 2012 R2, you can't install Visual Studio or SDK. You can use powershell to register assemblies into GAC. It didn't need any special installation for me.

Set-location "C:\Temp"
[System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")
$publish = New-Object System.EnterpriseServices.Internal.Publish
$publish.GacInstall("C:\Temp\myGacLibrary.dll")

If you need to get the name and PublicKeyToken see this question.

JPanel is almost always the wrong class to subclass. Why wouldn't you subclass JComponent?

There is a slight problem with ImageIcon in that the constructor blocks reading the image. Not really a problem when loading from the application jar, but maybe if you're potentially reading over a network connection. There's plenty of AWT-era examples of using MediaTracker, ImageObserver and friends, even in the JDK demos.
