On iOS 7:

[[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:(38.0/255.0) green:(38.0/255.0) blue:(38.0/255.0) alpha:1.0]];

I also recommend setting first depending on your visual desires:

[[UITabBar appearance] setBarStyle:UIBarStyleBlack];

The bar style puts a subtle separator between your view content and your tab bar.

I just patch nginx binary replacing path /var/log/nginx/error.log and other with local path.

$ perl -pi \
    -e 's@/var/log/nginx/@_var_log_nginx/@g;' \
    -e 's@/var/lib/nginx/@_var_lib_nginx/@g;' \
    -e 's@/var/run/nginx.pid@_var_run/nginx.pid@g;' \
    -e 's@/run/nginx.pid@_run/nginx.pid@g;' \
    < /usr/sbin/nginx > nginx
$ chmod +x nginx
$ mkdir _var_log_nginx _var_lib_nginx _var_run _run
$ ./nginx -p . -c nginx.conf

It works for testing.

I had that problem with my server hosted in the cloud. I only need the server a couple of times a year and so when I boot up my server the IP address changes. The new IP address then has to be updated on FTP Server passive mode settings!

The latest version of Filezilla works just fine!

First off, it might not be good to just go by recall alone. You can simply achieve a recall of 100% by classifying everything as the positive class. I usually suggest using AUC for selecting parameters, and then finding a threshold for the operating point (say a given precision level) that you are interested in.

For how class_weight works: It penalizes mistakes in samples of class[i] with class_weight[i] instead of 1. So higher class-weight means you want to put more emphasis on a class. From what you say it seems class 0 is 19 times more frequent than class 1. So you should increase the class_weight of class 1 relative to class 0, say {0:.1, 1:.9}. If the class_weight doesn't sum to 1, it will basically change the regularization parameter.

For how class_weight="auto" works, you can have a look at this discussion. In the dev version you can use class_weight="balanced", which is easier to understand: it basically means replicating the smaller class until you have as many samples as in the larger one, but in an implicit way.

If it has to be "nested", this would be one way, to get your job done:

SELECT o.name AS country, o.headofstate 
FROM   country o
WHERE  o.headofstate like 'A%'
AND   (
    SELECT i.population
    FROM   city i
    WHERE  i.id = o.capital
    ) > 100000

A JOIN would be more efficient than a correlated subquery, though. Can it be, that who ever gave you that task is not up to speed himself?

To set Roboto programmatically:

paint.setTypeface(Typeface.create("sans-serif-thin", Typeface.NORMAL));

If you assume just one result you could do this as in Edwin suggested by using specific users id.

$someUserId = 'abc123';

$stmt = $mysqli->prepare("SELECT ssfullname, ssemail FROM userss WHERE user_id = ?");
$stmt->bind_param('s', $someUserId);

$stmt->execute();

$stmt->bind_result($ssfullname, $ssemail);
$stmt->store_result();
$stmt->fetch();

ChromePhp::log($ssfullname, $ssemail); //log result in chrome if ChromePhp is used.

OR as "Your Common Sense" which selects just one user.

$stmt = $mysqli->prepare("SELECT ssfullname, ssemail FROM userss ORDER BY ssid LIMIT 1");

$stmt->execute();
$stmt->bind_result($ssfullname, $ssemail);
$stmt->store_result();
$stmt->fetch();

Nothing really different from the above except for PHP v.5

Pass a ref if you want to change what the object is:

TestRef t = new TestRef();
t.Something = "Foo";
DoSomething(ref t);

void DoSomething(ref TestRef t)
{
  t = new TestRef();
  t.Something = "Not just a changed t, but a completely different TestRef object";
}

After calling DoSomething, t does not refer to the original new TestRef, but refers to a completely different object.

This may be useful too if you want to change the value of an immutable object, e.g. a string. You cannot change the value of a string once it has been created. But by using a ref, you could create a function that changes the string for another one that has a different value.

It is not a good idea to use ref unless it is needed. Using ref gives the method freedom to change the argument for something else, callers of the method will need to be coded to ensure they handle this possibility.

Also, when the parameter type is an object, then object variables always act as references to the object. This means that when the ref keyword is used you've got a reference to a reference. This allows you to do things as described in the example given above. But, when the parameter type is a primitive value (e.g. int), then if this parameter is assigned to within the method, the value of the argument that was passed in will be changed after the method returns:

int x = 1;
Change(ref x);
Debug.Assert(x == 5);
WillNotChange(x);
Debug.Assert(x == 5); // Note: x doesn't become 10

void Change(ref int x)
{
  x = 5;
}

void WillNotChange(int x)
{
  x = 10;
}

As Richard said, StringWriter is the way forward. There's one snag, however: by default, StringWriter will advertise itself as being in UTF-16. Usually XML is in UTF-8. You can fix this by subclassing StringWriter;

public class Utf8StringWriter : StringWriter
{
    public override Encoding Encoding
    {
         get { return Encoding.UTF8; }
    }
}

This will affect the declaration written by XmlWriter. Of course, if you then write the string out elsewhere in binary form, make sure you use an encoding which matches whichever encoding you fix for the StringWriter. (The above code always assumes UTF-8; it's trivial to make a more general version which accepts an encoding in the constructor.)

You'd then use:

using (TextWriter writer = new Utf8StringWriter())
{
    using (XmlWriter xmlWriter = XmlWriter.Create(writer))
    {
        ...
    }
    return writer.ToString();
}

I solved this in my env, without modify hadoop-env.sh

You'd be better using /bin/bash as default shell not /bin/sh

Check these before:

1. You have already config java and env (success echo $JAVA_HOME)
2. right config hadoop

echo $SHELL in every node, check if print /bin/bash if not, vi /etc/passwd, add /bin/bash at tail of your username ref

If you think the performance of the query will be better using the index, how could you force the query to use the index?

First you would of course verify that the index gave a better result for returning the complete data set, right?

The index hint is the key here, but the more up to date way of specifying it is with the column naming method rather than the index naming method. In your case you would use:

select /*+ index(table_name (column_having_index)) */ *
from   table_name
where  column_having_index="some value"; 

In more complex cases you might ...

select /*+ index(t (t.column_having_index)) */ *
from   my_owner.table_name t,
       ...
where  t.column_having_index="some value"; 

With regard to composite indexes, I'm not sure that you need to specify all columns, but it seems like a good idea. See the docs here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#autoId18 on multiple index_specs and use of index_combine for multiple indexes, and here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#BABGFHCH for the specification of multiple columns in the index_spec.

You are getting close!

# Find all of the text between paragraph tags and strip out the html
page = soup.find('p').getText()

Using find (as you've noticed) stops after finding one result. You need find_all if you want all the paragraphs. If the pages are formatted consistently ( just looked over one), you could also use something like

soup.find('div',{'id':'ctl00_PlaceHolderMain_RichHtmlField1__ControlWrapper_RichHtmlField'})

to zero in on the body of the article.

<a ngHref="/path/{{obj.val1}}/{{obj.val2}}">{{obj.val1}}, {{obj.val2}}</a>

Declaration of new variables in case statements is what causing problems. Enclosing all case statements in {} will limit the scope of newly declared variables to the currently executing case which solves the problem.

switch(choice)
{
    case 1: {
       // .......
    }break;
    case 2: {
       // .......
    }break;
    case 3: {
       // .......
    }break;
}    

Just use Request.QueryString.ToString() to get full query string, like this:

string URL = "http://www.example.com/rendernews.php?"+Request.Querystring.ToString();

Presumably, that's the Lombok @Slf4j annotation you're using. You'll need to install the Lombok plugin in IntelliJ if you want IntelliJ to recognize Lombok annotations. Otherwise, what do you expect if you try to use a field that doesn't exist?

We control fork() process call by if, else statement. See my code below:

int main()
{
   int forkresult, parent_ID;

   forkresult=fork();
   if(forkresult !=0 )
   {
        printf(" I am the parent my ID is = %d" , getpid());
        printf(" and my child ID is = %d\n" , forkresult);
   }
   parent_ID = getpid();

   if(forkresult ==0)
      printf(" I am the  child ID is = %d",getpid());
   else
      printf(" and my parent ID is = %d", parent_ID);
}

please try this

echo $VAR | grep ClNonZ | awk '{print $3}';

or

echo cat filename | grep ClNonZ | awk '{print $3}';

Assuming your RDD[row] is called rdd, you can use:

val sqlContext = new SQLContext(sc) 
import sqlContext.implicits._
rdd.toDF()

Use bin folder and exe instead. Path will be C:\Program Files (x86)\Git\bin\git.exe

Also sometimes it doesn't work if there are blank spaces in path name as in your program files directory name.

In that case, copy the whole git folder to root of partition and then link studio to it

How about put jTextField.requestFocusInWindow(); into jTextField FocusLost event? Works for me have 5 controls on JPanel Soon as click on MessageBox, focus lost on jTextField. Used all the suggested codes but no luck Only above method works my case.

I would use specific user (and NOT Application user). Then I will enable impersonation in the application. Once you do that whatever account is set as the specific user, those credentials would used to access local resources on that server (Not for external resources).

Specific User setting is specifically meant for accessing local resources.

My solution is to use ggplot2. It takes care of these types of things automatically. The biggest thing is to arrange the data appropriately.

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)
df <- data.frame(x=rep(x,2), y=c(y1, y2), class=c(rep("y1", 5), rep("y2", 5)))

Then use ggplot2 to plot it

library(ggplot2)
ggplot(df, aes(x=x, y=y, color=class)) + geom_point()

This is saying plot the data in df, and separate the points by class.

The plot generated is

Ran into a similar issue the solution for me was to run fuser -k 'filename.db' on the file that had a lock associated with it.

Hope this helps!

When submitting a form, you tell your browser to send, via the HTTP protocol, a message on the network, properly enveloped in a TCP/IP protocol message structure. An HTML page has a way to send data to the server: by using <form>s.

When a form is submitted, an HTTP Request is created and sent to the server, the message will contain the field names in the form and the values filled in by the user. This transmission can happen with POST or GET HTTP methods.

• POST tells your browser to build an HTTP message and put all content in the body of the message (a very useful way of doing things, more safe and also flexible).
• GET will submit the form data in the querystring. It has some constraints about data representation and length.

Stating how to send your form to the server

Attribute enctype has sense only when using POST method. When specified, it instructs the browser to send the form by encoding its content in a specific way. From MDN - Form enctype:

When the value of the method attribute is post, enctype is the MIME type of content that is used to submit the form to the server.

• application/x-www-form-urlencoded: This is the default. When the form is sent, all names and values are collected and URL Encoding is performed on the final string.
• multipart/form-data: Characters are NOT encoded. This is important when the form has a file upload control. You want to send the file binary and this ensures that bitstream is not altered.
• text/plain: Spaces get converted, but no more encoding is performed.

Security

When submitting forms, some security concerns can arise as stated in RFC 7578 Section 7: Multipart form data - Security considerations:

All form-processing software should treat user supplied form-data
with sensitivity, as it often contains confidential or personally
identifying information. There is widespread use of form "auto-fill" features in web browsers; these might be used to trick users to
unknowingly send confidential information when completing otherwise
innocuous tasks. multipart/form-data does not supply any features
for checking integrity, ensuring confidentiality, avoiding user
confusion, or other security features; those concerns must be
addressed by the form-filling and form-data-interpreting applications.

Applications that receive forms and process them must be careful not to supply data back to the requesting form-processing site that was not intended to be sent.

It is important when interpreting the filename of the Content-
Disposition header field to not inadvertently overwrite files in the
recipient's file space.

This concerns you if you are a developer and your server will process forms submitted by users which might end up containing sensitive information.

Here is a method, which does not use jQuery. I used it to create a bookmarklet, which checks the current page on w3-html-validator.

var f = document.createElement('form');
f.action='http://validator.w3.org/check';
f.method='POST';
f.target='_blank';

var i=document.createElement('input');
i.type='hidden';
i.name='fragment';
i.value='<!DOCTYPE html>'+document.documentElement.outerHTML;
f.appendChild(i);

document.body.appendChild(f);
f.submit();

Just to update Gabe Sechan's answer. If your manifest asks for permissions to READ_CALL_LOG and READ_PHONE_STATE, onReceive will called TWICE. One of which has EXTRA_INCOMING_NUMBER in it and the other doesn't. You have to test which has it and it can occur in any order.

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

If you are moving branches to a new repo from an old one and do NOT have all the old repo branches local, you will need to track them first.

for remote in `git branch -r | grep -v '\->'`; do git branch --track $remote; done

Then add your new remote repo:

git remote add bb <path-to-new-repo>

Then you can push all using this command:

git push -u bb --all

Or you can configure the repo using the git config commands noted in the other responses here if you are not doing this one time or are only looking to move local branches.

The important point, the other responses only push all LOCAL branches. If the branches only exist on an alternate REMOTE repository they will not move without tracking them first. The for loop presented here will help with that.

Best way is to Use a Python Web Frame Work you can choose Django/Flask. I will suggest you to Use Django because it's more powerful. Here is Step by guide to get complete your task :

pip install django
django-admin createproject buttonpython

then you have to create a file name views.py in buttonpython directory.

write below code in views.py:

from django.http import HttpResponse

def sample(request):
    #your python script code
    output=code output
    return HttpResponse(output)

Once done navigate to urls.py and add this stanza

from . import views

path('', include('blog.urls')),

Now go to parent directory and execute manage.py

python manage.py runserver 127.0.0.1:8001

Step by Step Guide in Detail: Run Python script on clicking HTML button

You could use IllegalArgumentException:

public void speedDown(int decrement)
{
    if(speed - decrement < 0){
        throw new IllegalArgumentException("Final speed can not be less than zero");
    }else{
        speed -= decrement;
    }
}

Put it in a TRY/CATCH.

When RAISERROR is run with a severity of 11 or higher in a TRY block, it transfers control to the associated CATCH block

I'm assuming you're using jquery to make the AJAX call so you can do this pretty easily by putting the redirect in the success like so:

    $.ajax({
       url: 'ajax_location.html',
       success: function(data) {
          //this is the redirect
          document.location.href='/newpage/';
       }
    });

Those are the home directories of the users. Try cd ~(your username), for example.

Make sure the file names do not contain special characters such as ñ for example

From the Lifecycle reference, install will run the project's integration tests, package won't.

If you really need to not install the generated artifacts, use at least verify.

Help for me

series.str.cat is the most flexible way to approach this problem:

For df = pd.DataFrame({'foo':['a','b','c'], 'bar':[1, 2, 3]})

df.foo.str.cat(df.bar.astype(str), sep=' is ')

>>>  0    a is 1
     1    b is 2
     2    c is 3
     Name: foo, dtype: object

OR

df.bar.astype(str).str.cat(df.foo, sep=' is ')

>>>  0    1 is a
     1    2 is b
     2    3 is c
     Name: bar, dtype: object

Unlike .join() (which is for joining list contained in a single Series), this method is for joining 2 Series together. It also allows you to ignore or replace NaN values as desired.

For updating a record:

 UPDATE Employees SET [Photo] = (SELECT
 MyImage.* from Openrowset(Bulk
 'C:\photo.bmp', Single_Blob) MyImage)
 where Id = 10

Notes:

• Make sure to add the 'BULKADMIN' Role Permissions for the login you are using.
• Paths are not pointing to your computer when using SQL Server Management Studio. If you start SSMS on your local machine and connect to a SQL Server instance on server X, the file C:\photo.bmp will point to hard drive C: on server X, not your machine!

If you are using Xcode 8 and swift 3. Use the following way to get the UIColor

This code works on ROOTED phones:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        String[] cmds = {"cd /system/bin" ,"settings put secure location_providers_allowed +gps"};
        try {
            Process p = Runtime.getRuntime().exec("su");
            DataOutputStream os = new DataOutputStream(p.getOutputStream());
            for (String tmpCmd : cmds) {
                os.writeBytes(tmpCmd + "\n");
            }
            os.writeBytes("exit\n");
            os.flush();
        }
        catch (IOException e){
            e.printStackTrace();
        }
    }
}

For turning off GPS you can use this command instead

settings put secure location_providers_allowed -gps

You can also toggle network accuracy using the following commands: for turning on use:

settings put secure location_providers_allowed +network

and for turning off you can use:

settings put secure location_providers_allowed -network

I had a similar issue with Datagrip and none of these solutions worked.

Once I restarted the Datagrip Client it was no longer an issue and I could drop tables again.

Expanding on betabandido's answer, you could write a function to inject the attributes as constants into the module:

def module_register_class_constants(klass, attr_prefix):
    globals().update(
        (name, getattr(klass, name)) for name in dir(klass) if name.startswith(attr_prefix)
    )

class Animal(object):
    SIZE_HUGE = "Huge"
    SIZE_BIG = "Big"

module_register_class_constants(Animal, "SIZE_")

class Horse(Animal):
    def printSize(self):
        print SIZE_BIG

I guess you want

last_index = len(list1) - 1 

which would store 3 in last_index.

Don't know if this question is relevant anymore, but this happened to me on a client wich had an incorrect datetime set on Windows. This will be an alternative to watch. If is this case, it will reproduce on other browsers as well (at least, on firefox and chrome).

I fixed it updating datetime on Windows to actual's real datetime. Hope it helps somebody.

This maybe what you're looking for:

awk 'BEGIN {FS=" ";} {printf "'\''%s'\'' ", $1}'

That is, with '\'' you close the opening ', then print a literal ' by escaping it and finally open the ' again.

You can use dt2.Value.ToString("format"), but of course that requires that dt2 != null, and that negates th use of a nullable type in the first place.

There are several solutions here, but the big question is: How do you want to format a null date?

If you're using a graphical tool. It shows you the schema right next to the table name. In case of DB Browser For Sqlite, click to open the database(top right corner), navigate and open your database, you'll see the information populated in the table as below.

right click on the record/table_name, click on copy create statement and there you have it.

Hope it helped some beginner who failed to work with the commandline.

Here you can simply use:

SendKeys "{ENTER}" at the end of code linked to the Username field.

And so you can skip pressing ENTER Key once (one time).
And as a result, the next button ("Log In" button here) will be activated. And when you press ENTER once (your desired outcome), It will run code which is linked with "Log In" button.

You can use <Text> like a container for your other text components. This is example:

...
<Text>
  <Text>This is a sentence</Text>
  <Text style={{fontWeight: "bold"}}> with</Text>
  <Text> one word in bold</Text>
</Text>
...

Here is an example.

You can't do this using forms the normal way. Instead, you want to use AJAX.

A sample function that will submit the data and alert the page response.

function submitForm() {
    var http = new XMLHttpRequest();
    http.open("POST", "<<whereverTheFormIsGoing>>", true);
    http.setRequestHeader("Content-type","application/x-www-form-urlencoded");
    var params = "search=" + <<get search value>>; // probably use document.getElementById(...).value
    http.send(params);
    http.onload = function() {
        alert(http.responseText);
    }
}

Many developers include files by pointing to a remote URL, even if the file is within the local system. For example:

<php include("http://example.com/includes/example_include.php"); ?>

With allow_url_include disabled, this method does not work. Instead, the file must be included with a local path, and there are three methods of doing this:

By using a relative path, such as ../includes/example_include.php. By using an absolute path (also known as relative-from-root), such as /home/username/example.com/includes/example_include.php.

By using the PHP environment variable $_SERVER['DOCUMENT_ROOT'], which returns the absolute path to the web root directory. This is by far the best (and most portable) solution. The following example shows the environment variable in action.

Example Include

<?php include($_SERVER['DOCUMENT_ROOT']."/includes/example_include.php"); ?>

I have never seen it done that way in JavaScript. If you want a function with optional parameters that get assigned default values if the parameters are omitted, here's a way to do it:

 function(a, b) {
      if (typeof a == "undefined") {
        a = 10;
      }

      if (typeof b == "undefined") {
        a = 20;
      }

      alert("a: " + a + " b: " + b);
    }

You can use the extra arguments to setTimeout to pass parameters to the callback function.

for (var i = 1; i <= 2; i++) {
    setTimeout(function(j) { alert(j) }, 100, i);
}

Note: This doesn't work on IE9 and below browsers.

If you want to keep the GNU compiler extensions, use -std=gnu++0x rather than -std=c++0x. Here's a quote from the man page:

The compiler can accept several base standards, such as c89 or c++98, and GNU dialects of those standards, such as gnu89 or gnu++98. By specifying a base standard, the compiler will accept all programs following that standard and those using GNU extensions that do not contradict it. For example, -std=c89 turns off certain features of GCC that are incompatible with ISO C90, such as the "asm" and "typeof" keywords, but not other GNU extensions that do not have a meaning in ISO C90, such as omitting the middle term of a "?:" expression. On the other hand, by specifying a GNU dialect of a standard, all features the compiler support are enabled, even when those features change the meaning of the base standard and some strict-conforming programs may be rejected. The particular standard is used by -pedantic to identify which features are GNU extensions given that version of the standard. For example-std=gnu89 -pedantic would warn about C++ style // comments, while -std=gnu99 -pedantic would not.

Base64 overhead is 33%.

BaseXML for XML1.0 overhead is only 20%. But it's not a standard and only have a C implementation yet. Check it out if you're concerned with data size. Note that however browsers tends to implement compression so that it is less needed.

I developed it after the discussion in this thread: Encoding binary data within XML : alternatives to base64.

I would use it at every opportunity. See When do you use Java's @Override annotation and why?

This is not exactly beautiful but without extra software

class timeit():
    from datetime import datetime
    def __enter__(self):
        self.tic = self.datetime.now()
    def __exit__(self, *args, **kwargs):
        print('runtime: {}'.format(self.datetime.now() - self.tic))

Then you can run it like:

with timeit():

Try using rowMeans:

z$mean=rowMeans(z[,c("x", "y")], na.rm=TRUE)

  w x  y mean
1 5 1  1    1
2 6 2  2    2
3 7 3  3    3
4 8 4 NA    4

For some (like me) that nothing else worked, try this:

brew cleanup
brew link node
brew uninstall node
brew install node

Here is a jsfiddle

It provides the abbreviation of the current user timezone.

Here is the code sample

var tz = jstz.determine();
console.log(tz.name());
console.log(moment.tz.zone(tz.name()).abbr(new Date().getTime()));

document.getElementById('<%=hdntxtbxTaksit.ClientID%>').value

The id you set in server is the server id which is different from client id.

Try the below code. I am using this code for opening a PDF file. You can use it for other files also.

File file = new File(Environment.getExternalStorageDirectory(),
                     "Report.pdf");
Uri path = Uri.fromFile(file);
Intent pdfOpenintent = new Intent(Intent.ACTION_VIEW);
pdfOpenintent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
pdfOpenintent.setDataAndType(path, "application/pdf");
try {
    startActivity(pdfOpenintent);
}
catch (ActivityNotFoundException e) {

}

If you want to open files, you can change the setDataAndType(path, "application/pdf"). If you want to open different files with the same intent, you can use Intent.createChooser(intent, "Open in...");. For more information, look at How to make an intent with multiple actions.

x_file = open(os.path.join(direct, '5_1.txt'), 'r')

The WHY: dates are objects

In Python, dates are objects. Therefore, when you manipulate them, you manipulate objects, not strings or timestamps.

Any object in Python has TWO string representations:

• The regular representation that is used by print can be get using the str() function. It is most of the time the most common human readable format and is used to ease display. So str(datetime.datetime(2008, 11, 22, 19, 53, 42)) gives you '2008-11-22 19:53:42'.

• The alternative representation that is used to represent the object nature (as a data). It can be get using the repr() function and is handy to know what kind of data your manipulating while you are developing or debugging. repr(datetime.datetime(2008, 11, 22, 19, 53, 42)) gives you 'datetime.datetime(2008, 11, 22, 19, 53, 42)'.

What happened is that when you have printed the date using print, it used str() so you could see a nice date string. But when you have printed mylist, you have printed a list of objects and Python tried to represent the set of data, using repr().

The How: what do you want to do with that?

Well, when you manipulate dates, keep using the date objects all long the way. They got thousand of useful methods and most of the Python API expect dates to be objects.

When you want to display them, just use str(). In Python, the good practice is to explicitly cast everything. So just when it's time to print, get a string representation of your date using str(date).

One last thing. When you tried to print the dates, you printed mylist. If you want to print a date, you must print the date objects, not their container (the list).

E.G, you want to print all the date in a list :

for date in mylist :
    print str(date)

Note that in that specific case, you can even omit str() because print will use it for you. But it should not become a habit :-)

Practical case, using your code

import datetime
mylist = []
today = datetime.date.today()
mylist.append(today)
print mylist[0] # print the date object, not the container ;-)
2008-11-22

# It's better to always use str() because :

print "This is a new day : ", mylist[0] # will work
>>> This is a new day : 2008-11-22

print "This is a new day : " + mylist[0] # will crash
>>> cannot concatenate 'str' and 'datetime.date' objects

print "This is a new day : " + str(mylist[0]) 
>>> This is a new day : 2008-11-22

Advanced date formatting

Dates have a default representation, but you may want to print them in a specific format. In that case, you can get a custom string representation using the strftime() method.

strftime() expects a string pattern explaining how you want to format your date.

E.G :

print today.strftime('We are the %d, %b %Y')
>>> 'We are the 22, Nov 2008'

All the letter after a "%" represent a format for something:

• %d is the day number (2 digits, prefixed with leading zero's if necessary)
• %m is the month number (2 digits, prefixed with leading zero's if necessary)
• %b is the month abbreviation (3 letters)
• %B is the month name in full (letters)
• %y is the year number abbreviated (last 2 digits)
• %Y is the year number full (4 digits)

etc.

Have a look at the official documentation, or McCutchen's quick reference you can't know them all.

Since PEP3101, every object can have its own format used automatically by the method format of any string. In the case of the datetime, the format is the same used in strftime. So you can do the same as above like this:

print "We are the {:%d, %b %Y}".format(today)
>>> 'We are the 22, Nov 2008'

The advantage of this form is that you can also convert other objects at the same time.
With the introduction of Formatted string literals (since Python 3.6, 2016-12-23) this can be written as

import datetime
f"{datetime.datetime.now():%Y-%m-%d}"
>>> '2017-06-15'

Localization

Dates can automatically adapt to the local language and culture if you use them the right way, but it's a bit complicated. Maybe for another question on SO(Stack Overflow) ;-)

I use the following code:

namespace Core
{
    typedef std::wstring String;

    void SplitString(const Core::String& input, const Core::String& splitter, std::list<Core::String>& output)
    {
        if (splitter.empty())
        {
            throw std::invalid_argument(); // for example
        }

        std::list<Core::String> lines;

        Core::String::size_type offset = 0;

        for (;;)
        {
            Core::String::size_type splitterPos = input.find(splitter, offset);

            if (splitterPos != Core::String::npos)
            {
                lines.push_back(input.substr(offset, splitterPos - offset));
                offset = splitterPos + splitter.size();
            }
            else
            {
                lines.push_back(input.substr(offset));
                break;
            }
        }

        lines.swap(output);
    }
}

C99 has a boolean datatype, actually, but if you must use older versions, just define a type:

typedef enum {false=0, true=1} bool;

Installing

gem 'remotipart' 

can help

Step 1) Remove the semi-colon, it's an object you're creating...

a(this).next().css({
    left       : c,
    transition : 'opacity 1s ease-in-out';
});

to

a(this).next().css({
    left       : c,
    transition : 'opacity 1s ease-in-out'
});

Step 2) Vendor-prefixes... no browsers use transition since it's the standard and this is an experimental feature even in the latest browsers:

a(this).next().css({
    left             : c,
    WebkitTransition : 'opacity 1s ease-in-out',
    MozTransition    : 'opacity 1s ease-in-out',
    MsTransition     : 'opacity 1s ease-in-out',
    OTransition      : 'opacity 1s ease-in-out',
    transition       : 'opacity 1s ease-in-out'
});

Here is a demo: http://jsfiddle.net/83FsJ/

Step 3) Better vendor-prefixes... Instead of adding tons of unnecessary CSS to elements (that will just be ignored by the browser) you can use jQuery to decide what vendor-prefix to use:

$('a').on('click', function () {
    var myTransition = ($.browser.webkit)  ? '-webkit-transition' :
                       ($.browser.mozilla) ? '-moz-transition' : 
                       ($.browser.msie)    ? '-ms-transition' :
                       ($.browser.opera)   ? '-o-transition' : 'transition',
        myCSSObj     = { opacity : 1 };

    myCSSObj[myTransition] = 'opacity 1s ease-in-out';
    $(this).next().css(myCSSObj);
});?

Here is a demo: http://jsfiddle.net/83FsJ/1/

Also note that if you specify in your transition declaration that the property to animate is opacity, setting a left property won't be animated.

I suggest using jerkson, it supports most basic type conversions:

scala> import com.codahale.jerkson.Json._

scala> val l = List( 
                 Map( "id" -> 1, "name" -> "John" ),
                 Map( "id" -> 2, "name" -> "Dani")
               )

scala> generate( l )

res1: String = [{"id":1,"name":"John"},{"id":2,"name":"Dani"}]

while Alexey Kukanov's answer may be more efficient, you can also iterate through a queue in a very natural manner, by popping each element from the front of the queue, then pushing it to the back:

#include <iostream>
#include <queue>

using namespace std;

int main() {
    //populate queue
    queue<int> q;
    for (int i = 0; i < 10; ++i) q.push(i);

    // iterate through queue
    for (size_t i = 0; i < q.size(); ++i) {
        int elem = std::move(q.front());
        q.pop();
        elem *= elem;
        q.push(std::move(elem));
    }

    //print queue
    while (!q.empty()) {
        cout << q.front() << ' ';
        q.pop();
    }
}

output:

0 1 4 9 16 25 36 49 64 81 

I prefer RENAME rather than DELETE

All my branches are named in the form of

• Fix/fix-<somedescription> or
• Ftr/ftr-<somedescription> or
• etc.

Using Tower as my git front end, it neatly organizes all the Ftr/, Fix/, Test/ etc. into folders.
Once I am done with a branch, I rename them to Done/...-<description>.

That way they are still there (which can be handy to provide history) and I can always go back knowing what it was (feature, fix, test, etc.)

cat * | grep -c string

I had the same error and just wanted to share my solution. In turned out that the minified version of popper had the code in the same line as the comment and so the entire code was commented out. I just pressed enter after the actual comment so the code was on a new line and then it worked fine.

The problem is that it triggers the form submission. If you make the getData function return false then it should stop the form from submitting.

Alternatively, you could also use the preventDefault method of the event object:

function getData(e) {
    e.preventDefault();
}

ps -o ppid=$(ps -ax | grep nameOfProcess | awk '{print $1}')

Prints out the changing process pid and then the parent PID. You can then kill the parent, or you can use that parentPID in the following command to get the name of the parent process:

ps -p parentPID -o comm=

For me the parent was 'login' :\

Python don't have a great support for recursion because of it's lack of TRE (Tail Recursion Elimination).

This means that each call to your recursive function will create a function call stack and because there is a limit of stack depth (by default is 1000) that you can check out by sys.getrecursionlimit (of course you can change it using sys.setrecursionlimit but it's not recommended) your program will end up by crashing when it hits this limit.

As other answer has already give you a much nicer way for how to solve this in your case (which is to replace recursion by simple loop) there is another solution if you still want to use recursion which is to use one of the many recipes of implementing TRE in python like this one.

N.B: My answer is meant to give you more insight on why you get the error, and I'm not advising you to use the TRE as i already explained because in your case a loop will be much better and easy to read.

IDLE's console does not support ANSI escape sequences, or any other form of escapes for coloring your output.

You can learn how to talk to IDLE's console directly instead of just treating it like normal stdout and printing to it (which is how it does things like color-coding your syntax), but that's pretty complicated. The idle documentation just tells you the basics of using IDLE itself, and its idlelib library has no documentation (well, there is a single line of documentation—"(New in 2.3) Support library for the IDLE development environment."—if you know where to find it, but that isn't very helpful). So, you need to either read the source, or do a whole lot of trial and error, to even get started.

Alternatively, you can run your script from the command line instead of from IDLE, in which case you can use whatever escape sequences your terminal handles. Most modern terminals will handle at least basic 16/8-color ANSI. Many will handle 16/16, or the expanded xterm-256 color sequences, or even full 24-bit colors. (I believe gnome-terminal is the default for Ubuntu, and in its default configuration it will handle xterm-256, but that's really a question for SuperUser or AskUbuntu.)

Learning to read the termcap entries to know which codes to enter is complicated… but if you only care about a single console—or are willing to just assume "almost everything handles basic 16/8-color ANSI, and anything that doesn't, I don't care about", you can ignore that part and just hardcode them based on, e.g., this page.

Once you know what you want to emit, it's just a matter of putting the codes in the strings before printing them.

But there are libraries that can make this all easier for you. One really nice library, which comes built in with Python, is curses. This lets you take over the terminal and do a full-screen GUI, with colors and spinning cursors and anything else you want. It is a little heavy-weight for simple uses, of course. Other libraries can be found by searching PyPI, as usual.

it works in Linux. perhaps there are system settings which can be changed in Windows to allow it.

jcomeau@aspire:/tmp$ cat test.java; javac test.java; java test
import java.awt.event.*;
import java.awt.Robot;
public class test {
 public static void main(String args[]) {
  Robot bot = null;
  try {
   bot = new Robot();
  } catch (Exception failed) {
   System.err.println("Failed instantiating Robot: " + failed);
  }
  int mask = InputEvent.BUTTON1_DOWN_MASK;
  bot.mouseMove(100, 100);
  bot.mousePress(mask);
  bot.mouseRelease(mask);
 }
}

I'm assuming InputEvent.MOUSE_BUTTON1_DOWN in your version of Java is the same thing as InputEvent.BUTTON1_DOWN_MASK in mine; I'm using 1.6.

otherwise, that could be your problem. I can tell it worked because my Chrome browser was open to http://docs.oracle.com/javase/7/docs/api/java/awt/Robot.html when I ran the program, and it changed to Debian.org because that was the link in the bookmarks bar at (100, 100).

[added later after cogitating on it today] it might be necessary to trick the listening program by simulating a smoother mouse movement. see the answer here: How to move a mouse smoothly throughout the screen by using java?

<activity android:name="com.example.abc"

Just add android:configChanges="orientation|screenSize" in activity tab of manifest file.

So, Activity won't restart when orientation change.

I suggest a mix of using X-macros are the best solution and the following template functions:

To borrow off marcinkoziukmyopenidcom and extended

enum Colours {
#   define X(a) a,
#   include "colours.def"
#   undef X
    ColoursCount
};

char const* const colours_str[] = {
#   define X(a) #a,
#   include "colours.def"
#   undef X
    0
};

template <class T> T str2enum( const char* );
template <class T> const char* enum2str( T );

#define STR2ENUM(TYPE,ARRAY) \
template <> \
TYPE str2enum<TYPE>( const char* str ) \
    { \
    for( int i = 0; i < (sizeof(ARRAY)/sizeof(ARRAY[0])); i++ ) \
        if( !strcmp( ARRAY[i], str ) ) \
            return TYPE(i); \
    return TYPE(0); \
    }

#define ENUM2STR(TYPE,ARRAY) \
template <> \
const char* enum2str<TYPE>( TYPE v ) \
    { \
    return ARRAY[v]; \
    }

#define ENUMANDSTR(TYPE,ARRAY)\
    STR2ENUM(TYPE,ARRAY) \
    ENUM2STR(TYPE,ARRAY)

ENUMANDSTR(Colours,colours_str)

colour.def

X(Red)
X(Green)
X(Blue)
X(Cyan)
X(Yellow)
X(Magenta)

In Tomcat 7, 8, and 9 there is NO default user, so nobody can access a Manager app. You need to alter conf/tomcat-users.xml by adding new user with the role "manager-gui", like:

<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="manager-gui"/>

Look up here: https://www.mkyong.com/tomcat/tomcat-default-administrator-password/

What is the main difference. Like memory or performance implications

The difference between static and dynamic resources comes when the underlying object changes. If your Brush defined in the Resources collection were accessed in code and set to a different object instance, Rectangle will not detect this change.

Static Resources retrieved once by referencing element and used for the lifetime of the resources. Whereas, DynamicResources retrieve every time they are used.

The downside of Dynamic resources is that they tend to decrease application performance.

Are there rules in WPF like "brushes are always static" and "templates are always dynamic" etc.?

The best practice is to use Static Resources unless there is a specific reason like you want to change resource in the code behind dynamically. Another example of instance in which you would want t to use dynamic resoruces include when you use the SystemBrushes, SystenFonts and System Parameters.

Visual Studio looks for headers in this order:

• In the current source directory.
• In the Additional Include Directories in the project properties (Project -> [project name] Properties, under C/C++ | General).
• In the Visual Studio C++ Include directories under Tools ? Options ? Projects and Solutions ? VC++ Directories.
• In new versions of Visual Studio (2015+) the above option is deprecated and a list of default include directories is available at Project Properties ? Configuration ? VC++ Directories

In your case, add the directory that the header is to the project properties (Project Properties ? Configuration ? C/C++ ? General ? Additional Include Directories).

This should be faster.

while ($personCount < 10) {
    $result .= "{$personCount} people ";
    $personCount++;
}

echo $result;

foreach($i=0; $i<10; $i++){
    $v = @(array)$v;   
    // this could help defining $v as an array. 
    //@ is to supress undefined variable $v

    array_push($v, $i);
}

what about simply this:

byte[] args2 = getByteArry();
String byteStr = new String(args2);

Just a small addition to Jeff Bowman's excellent answer, as I found this question when searching for a solution to one of my own problems:

If a call to a method matches more than one mock's when trained calls, the order of the when calls is important, and should be from the most wider to the most specific. Starting from one of Jeff's examples:

when(foo.quux(anyInt(), anyInt())).thenReturn(true);
when(foo.quux(anyInt(), eq(5))).thenReturn(false);

is the order that ensures the (probably) desired result:

foo.quux(3 /*any int*/, 8 /*any other int than 5*/) //returns true
foo.quux(2 /*any int*/, 5) //returns false

If you inverse the when calls then the result would always be true.

I've just spent a while trying to get this to work an have a written a Ruby gem that accesses the API. You can read more on it's project page.

This is working code in Ruby:

require 'savon'
client = Savon::Client.new do
  wsdl.document = "http://realtime.nationalrail.co.uk/LDBWS/wsdl.aspx"
end

response = client.request 'http://thalesgroup.com/RTTI/2012-01-13/ldb/GetDepartureBoard' do

  namespaces = {
    "xmlns:soap" => "http://schemas.xmlsoap.org/soap/envelope/",
    "xmlns:xsi" => "http://www.w3.org/2001/XMLSchema-instance",
    "xmlns:xsd" => "http://www.w3.org/2001/XMLSchema"
  }

  soap.xml do |xml|
    xml.soap(:Envelope, namespaces) do |xml|
      xml.soap(:Header) do |xml|
        xml.AccessToken do |xml|
          xml.TokenValue('ENTER YOUR TOKEN HERE') 
        end
      end
      xml.soap(:Body) do |xml|
        xml.GetDepartureBoardRequest(xmlns: "http://thalesgroup.com/RTTI/2012-01-13/ldb/types") do |xml|
          xml.numRows(10)
          xml.crs("BHM")
          xml.filterCrs("BHM")
          xml.filterType("to")
        end
      end
    end
  end
end

Hope that's helpful for someone!

#1 I use the last one frequently when having buttons on the layout which are not generated (but static obviously).

If you use it in practice and in a business application, pay extra attention here, because when you use source obfuscater like ProGuard, you'll need to mark these methods in your activity as to not be obfuscated.

For archiving some kind of compile-time-security with this approach, have a look at Android Lint (example).

#2 Pros and cons for all methods are almost the same and the lesson should be:

Use what ever is most appropriate or feels most intuitive to you.

If you have to assign the same OnClickListener to multiple button instances, save it in the class-scope (#1). If you need a simple listener for a Button, make an anonymous implementation:

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        // Take action.
    }
});

I tend to not implement the OnClickListener in the activity, this gets a little confusing from time to time (especially when you implement multiple other event-handlers and nobody knows what this is all doing).

Exception code 0xc0000005 is an Access Violation. An AV at fault offset 0x00000000 means that something in your service's code is accessing a nil pointer. You will just have to debug the service while it is running to find out what it is accessing. If you cannot run it inside a debugger, then at least install a third-party exception logger framework, such as EurekaLog or MadExcept, to find out what your service was doing at the time of the AV.

In Netbeans 8 you may have to install the Tomcat plugin manually. After you download and extract Tomcat follow these steps:

1. Tools -> Plugins -> Available plugins, search for 'tomcat' and install the one named "Java EE Base plugin".
2. Restart Netbeans
3. On the project view (default left side of the screen), go to services, right click on Servers and then "Add Server"
4. Select Apache Tomcat, enter username and password and config the rest and finish

Using java 8:

This is a approach of Java-9 Map.ofEntries(Map.entry(k1,v1), Map.entry(k2,v2), ...)

public class MapUtil {
    import static java.util.stream.Collectors.toMap;

    import java.util.AbstractMap.SimpleEntry;
    import java.util.Map;
    import java.util.Map.Entry;
    import java.util.stream.Stream;

    private MapUtil() {}

    @SafeVarargs
    public static Map<String, Object> ofEntries(SimpleEntry<String, Object>... values) {
        return Stream.of(values).collect(toMap(Entry::getKey, Entry::getValue));
    }

    public static SimpleEntry<String, Object> entry(String key, Object value) {
        return new SimpleEntry<String, Object>(key, value);
    }
}

How to Use:

import static your.package.name.MapUtil.*;

import java.util.Map;

Map<String, Object> map = ofEntries(
        entry("id", 1),
        entry("description", "xyz"),
        entry("value", 1.05),
        entry("enable", true)
    );

Try this:

Dim Lastrow As Integer
Lastrow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row

Range("A2:L" & Lastrow).Select

Let's pretend that the value of Lastrow is 50. When you use the following:

Range("A2:L2" & Lastrow).Select

Then it is selecting a range from A2 to L250.

I was just having the same issue...

To resolve the problem (at least in my case) ensure you have included the lib folder in your bundle classpath:

Manifest-Version: 1.0
... 
Bundle-ClassPath: lib/gson-1.6.jar,
 .
...

Or if you want to include all jar's in the folder:

Bundle-ClassPath: lib/

You will still need to place the jar files on the java build path as shown above. Then your imported jar's should appear in the folder "Referenced Libraries"

Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as:

public String loadJSONFromAsset(Context context) {
        String json = null;
        try {
            InputStream is = context.getAssets().open("file_name.json");

            int size = is.available();

            byte[] buffer = new byte[size];

            is.read(buffer);

            is.close();

            json = new String(buffer, "UTF-8");


        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
        return json;

    }

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html

Hope you will get what you want.

I know I'm late :) But this how i do it:

public static void AddOrUpdateAppSettings(string key, string value)
{
    try
    {
        var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        var settings = configFile.AppSettings.Settings;
        if (settings[key] == null)
        {
            settings.Add(key, value);
        }
        else
        {
            settings[key].Value = value;
        }
        configFile.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
    }
    catch (ConfigurationErrorsException)
    {
        Console.WriteLine("Error writing app settings");
    }
}

For more information look at MSDN

cut -d: -f1

or

awk -F: '{print $1}'

or

sed 's/:.*//'

The fastest method is:

function escapeHTML(html) {
    return document.createElement('div').appendChild(document.createTextNode(html)).parentNode.innerHTML;
}

This method is about twice faster than the methods based on 'replace', see http://jsperf.com/htmlencoderegex/35 .

I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.

• If your request is XML Request use XML(text/xml).

• If your request is JSON Request use JSON(application/json)

You could try:

dict((k, bigdict[k]) for k in ('l', 'm', 'n'))

... or in Python 3 Python versions 2.7 or later (thanks to Fábio Diniz for pointing that out that it works in 2.7 too):

{k: bigdict[k] for k in ('l', 'm', 'n')}

Update: As Håvard S points out, I'm assuming that you know the keys are going to be in the dictionary - see his answer if you aren't able to make that assumption. Alternatively, as timbo points out in the comments, if you want a key that's missing in bigdict to map to None, you can do:

{k: bigdict.get(k, None) for k in ('l', 'm', 'n')}

If you're using Python 3, and you only want keys in the new dict that actually exist in the original one, you can use the fact to view objects implement some set operations:

{k: bigdict[k] for k in bigdict.keys() & {'l', 'm', 'n'}}

What you need to do is create a dataset. If you take a look at the quickstart guide, it shows you that you need to use the file object in order to create a dataset. So, f.create_dataset and then you can read the data. This is explained in the docs.

I couldn't locate boot2docker in my machine. So, I came up with something that worked for me.

$ sudo systemctl restart docker.socket docker.service
$ docker rm -f <container id>

Check if it helps you as well.

Assuming you have a char[fixed_size] rather than a char*, you can use a single, creative macro to do it all at once with a <<cout<<like ordering ("rather %s the disjointed %s\n", "than", "printf style format"). If you are working with embedded systems, this method will also allow you to leave out malloc and the large *printf family of functions like snprintf() (This keeps dietlibc from complaining about *printf too)

#include <unistd.h> //for the write example
//note: you should check if offset==sizeof(buf) after use
#define strcpyALL(buf, offset, ...) do{ \
    char *bp=(char*)(buf+offset); /*so we can add to the end of a string*/ \
    const char *s, \
    *a[] = { __VA_ARGS__,NULL}, \
    **ss=a; \
    while((s=*ss++)) \
         while((*s)&&(++offset<(int)sizeof(buf))) \
            *bp++=*s++; \
    if (offset!=sizeof(buf))*bp=0; \
}while(0)

char buf[256];
int len=0;

strcpyALL(buf,len,
    "The config file is in:\n\t",getenv("HOME"),"/.config/",argv[0],"/config.rc\n"
);
if (len<sizeof(buf))
    write(1,buf,len); //outputs our message to stdout
else
    write(2,"error\n",6);

//but we can keep adding on because we kept track of the length
//this allows printf-like buffering to minimize number of syscalls to write
//set len back to 0 if you don't want this behavior
strcpyALL(buf,len,"Thanks for using ",argv[0],"!\n");
if (len<sizeof(buf))
    write(1,buf,len); //outputs both messages
else
    write(2,"error\n",6);

• Note 1, you typically wouldn't use argv[0] like this - just an example
• Note 2, you can use any function that outputs a char*, including nonstandard functions like itoa() for converting integers to string types.
• Note 3, if you are already using printf anywhere in your program there is no reason not to use snprintf(), since the compiled code would be larger (but inlined and significantly faster)

If the folder is accessible from the browser (not outside the document root of your web server), then you just need to output links to the locations of those files. If they are outside the document root, you will need to have links, buttons, whatever, that point to a PHP script that handles getting the files from their location and streaming to the response.

Here is an updated macro based on the answer given above. This one should allow you to wrap your code even with a return statement.

#define SUPPRESS_PERFORM_SELECTOR_LEAK_WARNING(code)                        \
    _Pragma("clang diagnostic push")                                        \
    _Pragma("clang diagnostic ignored \"-Warc-performSelector-leaks\"")     \
    code;                                                                   \
    _Pragma("clang diagnostic pop")                                         \


SUPPRESS_PERFORM_SELECTOR_LEAK_WARNING(
    return [_target performSelector:_action withObject:self]
);

Your error is because you have:

     JOIN user ON article.author_id = user.id
LEFT JOIN user ON article.modified_by = user.id

You have two instances of the same table, but the database can't determine which is which. To fix this, you need to use table aliases:

     JOIN USER u ON article.author_id = u.id
LEFT JOIN USER u2 ON article.modified_by = u2.id

It's good habit to always alias your tables, unless you like writing the full table name all the time when you don't have situations like these.

The next issues to address will be:

SELECT article.* , section.title, category.title, user.name, user.name

1) Never use SELECT * - always spell out the columns you want, even if it is the entire table. Read this SO Question to understand why.

2) You'll get ambiguous column errors relating to the user.name columns because again, the database can't tell which table instance to pull data from. Using table aliases fixes the issue:

SELECT article.* , section.title, category.title, u.name, u2.name

For people who want to use another diff tool not listed in git, say with nvim. here is what I ended up using:

git config --global alias.d difftool -x <tool name>

In my case, I set <tool name> to nvim -d and invoke the diff command with

git d <file>

windows cmd: This would work if you have all te jars in the same directory and execute the below command

for /r %i in (*) do ( jar tvf %i | find /I "search_string")

I use a relative path solution,

./../../../../../images/img.png

every ../ will take you one folder up towards the root. Hope this helps..

2016 update: The easiest way is to use the Google Apps Script API, in particular the SpreadSheet Service. This works for private sheets, unlike the other answers that require the spreadsheet to be published.

This will let you bind JavaScript code to a Google Sheet, and execute it when the sheet is opened, or when a menu item (that you can define) is selected.

Here's a Quickstart/Demo. The code looks like this:

// Let's say you have a sheet of First, Last, email and you want to return the email of the
// row the user has placed the cursor on.
function getActiveEmail() {
  var activeSheet = SpreadsheetApp.getActiveSheet();
  var activeRow = .getActiveCell().getRow();
  var email = activeSheet.getRange(activeRow, 3).getValue();

  return email;
}

You can also publish such scripts as web apps.

Every instance of View calls getViewTreeObserver(). Now when holding an instance of ViewTreeObserver, you can add an OnScrollChangedListener() to it using the method addOnScrollChangedListener().

You can see more information about this class here.

It lets you be aware of every scrolling event - but without the coordinates. You can get them by using getScrollY() or getScrollX() from within the listener though.

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        int scrollY = rootScrollView.getScrollY(); // For ScrollView
        int scrollX = rootScrollView.getScrollX(); // For HorizontalScrollView
        // DO SOMETHING WITH THE SCROLL COORDINATES
    }
});

I think thats not the reason everybody told above. There is something wrong in your code, maybe miss spelling or mismatching with the database column names. If mysqli query gets no result then it will return false, so that it is not a object - is a wrong idea. Everything works fine. it returns 1 or 0 if query have result or not.

So, my suggestion is check your variable names and table column names or any other misspelling.

For a file:

if exist yourfilename (
  echo Yes 
) else (
  echo No
)

Replace yourfilename with the name of your file.

For a directory:

if exist yourfoldername\ (
  echo Yes 
) else (
  echo No
)

Replace yourfoldername with the name of your folder.

A trailing backslash (\) seems to be enough to distinguish between directories and ordinary files.

Use the ng-form directive inside of the tag in which you are using the ng-repeat directive. You can then use the scope created by the ng-form directive to reference a generic name. For example:

    <div class="form-group col-sm-6" data-ng-form="subForm" data-ng-repeat="field in justificationInfo.justifications"">

        <label for="{{field.label}}"><h3>{{field.label}}</h3></label>
        <i class="icon-valid" data-ng-show="subForm.input.$dirty && subForm.input.$valid"></i>
        <i class="icon-invalid" data-ng-show="subForm.input.$dirty && subForm.input.$invalid"></i>
        <textarea placeholder="{{field.placeholder}}" class="form-control" id="{{field.label}}" name="input" type="text" rows="3" data-ng-model="field.value" required>{{field.value}}</textarea>

    </div>

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

Scanf is pretty much always more trouble than it's worth. Here are two better ways to do what you're trying to do. This first one is a more-or-less direct translation of your code. It's longer, but you can look at it and see clearly what it does, unlike with scanf.

#include <stdio.h>
#include <ctype.h>
int main(void)
{
    char buf[1024], *p, *q;
    while (fgets(buf, 1024, stdin))
    {
        p = buf;
        while (*p)
        {
            while (*p && isspace(*p)) p++;
            q = p;
            while (*q && !isspace(*q)) q++;
            *q = '\0';
            if (p != q)
                puts(p);
            p = q;
        }
    }
    return 0;
}

And here's another version. It's a little harder to see what this does by inspection, but it does not break if a line is longer than 1024 characters, so it's the code I would use in production. (Well, really what I would use in production is tr -s '[:space:]' '\n', but this is how you implement something like that.)

#include <stdio.h>
#include <ctype.h>
int main(void)
{
    int ch, lastch = '\0';
    while ((ch = getchar()) != EOF)
    {
        if (!isspace(ch))
            putchar(ch);
        if (!isspace(lastch))
            putchar('\n');
        lastch = ch;
    }
    if (lastch != '\0' && !isspace(lastch))
        putchar('\n');
    return 0;
}

i had to figure out the right solution the hard way. the below code is part of cyanogenmod7 (the tablet tweaks) and is tested on android 2.3.3 / gingerbread.

methods:

• getForegroundApp - returns the foreground application.
• getActivityForApp - returns the activity of the found app.
• isStillActive - determines if a earlier found app is still the active app.
• isRunningService - a helper function for getForegroundApp

this hopefully answers this issue in all extend (:

private RunningAppProcessInfo getForegroundApp() {
    RunningAppProcessInfo result=null, info=null;

    if(mActivityManager==null)
        mActivityManager = (ActivityManager)mContext.getSystemService(Context.ACTIVITY_SERVICE);
    List <RunningAppProcessInfo> l = mActivityManager.getRunningAppProcesses();
    Iterator <RunningAppProcessInfo> i = l.iterator();
    while(i.hasNext()){
        info = i.next();
        if(info.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND
                && !isRunningService(info.processName)){
            result=info;
            break;
        }
    }
    return result;
}

private ComponentName getActivityForApp(RunningAppProcessInfo target){
    ComponentName result=null;
    ActivityManager.RunningTaskInfo info;

    if(target==null)
        return null;

    if(mActivityManager==null)
        mActivityManager = (ActivityManager)mContext.getSystemService(Context.ACTIVITY_SERVICE);
    List <ActivityManager.RunningTaskInfo> l = mActivityManager.getRunningTasks(9999);
    Iterator <ActivityManager.RunningTaskInfo> i = l.iterator();

    while(i.hasNext()){
        info=i.next();
        if(info.baseActivity.getPackageName().equals(target.processName)){
            result=info.topActivity;
            break;
        }
    }

    return result;
}

private boolean isStillActive(RunningAppProcessInfo process, ComponentName activity)
{
    // activity can be null in cases, where one app starts another. for example, astro
    // starting rock player when a move file was clicked. we dont have an activity then,
    // but the package exits as soon as back is hit. so we can ignore the activity
    // in this case
    if(process==null)
        return false;

    RunningAppProcessInfo currentFg=getForegroundApp();
    ComponentName currentActivity=getActivityForApp(currentFg);

    if(currentFg!=null && currentFg.processName.equals(process.processName) &&
            (activity==null || currentActivity.compareTo(activity)==0))
        return true;

    Slog.i(TAG, "isStillActive returns false - CallerProcess: " + process.processName + " CurrentProcess: "
            + (currentFg==null ? "null" : currentFg.processName) + " CallerActivity:" + (activity==null ? "null" : activity.toString())
            + " CurrentActivity: " + (currentActivity==null ? "null" : currentActivity.toString()));
    return false;
}

private boolean isRunningService(String processname){
    if(processname==null || processname.isEmpty())
        return false;

    RunningServiceInfo service;

    if(mActivityManager==null)
        mActivityManager = (ActivityManager)mContext.getSystemService(Context.ACTIVITY_SERVICE);
    List <RunningServiceInfo> l = mActivityManager.getRunningServices(9999);
    Iterator <RunningServiceInfo> i = l.iterator();
    while(i.hasNext()){
        service = i.next();
        if(service.process.equals(processname))
            return true;

    return false;
}

I always use pseudo elements :before and :after for changing the appearance of checkboxes and radio buttons. it's works like a charm.

Refer this link for more info

CODEPEN

Steps

1. Hide the default checkbox using css rules like visibility:hidden or opacity:0 or position:absolute;left:-9999px etc.
2. Create a fake checkbox using :before element and pass either an empty or a non-breaking space '\00a0';
3. When the checkbox is in :checked state, pass the unicode content: "\2713", which is a checkmark;
4. Add :focus style to make the checkbox accessible.
5. Done

Here is how I did it.

Structured Query Language - SQL: is an ANSI-standard used by almost all SGBD's vendors around the world. Basically, SQL is a language used to define and manipulate data [DDL and DML].

PL/SQL is a language created by Oracle universe. PL/SQL combine programming procedural instructions and allows the creation of programs that operates directly on database scenario.

T-SQL is Microsoft product align SQL patterns, with some peculiarities. So, feel free to test your limits.

If you have plugin for Maven in Eclipse, you can do following:

• right click on your project -> Maven -> Enable Dependency Management

This will convert your project to Maven and creates a pom.xml. Fast and simple...

If you bracket the @ you can use it directly

declare @TEMP table (ID int, Name varchar(max))
insert into @temp values (1,'one'), (2,'two')

SELECT * FROM @TEMP 
WHERE [@TEMP].[ID] = 1

Example of how to perform a INSERT INTO SELECT with a WHERE clause.

INSERT INTO #test2 (id) SELECT id FROM #test1 WHERE id > 2

Current answers are perfectly correct on how to create the aggregations, but none actually address the column alias/renaming that is also requested in the question.

Typically, this is how I handle this case:

val dimensionFields = List("col1")
val metrics = List("col2", "col3", "col4")
val columnOfInterests = dimensions ++ metrics

val df = spark.read.table("some_table"). 
    .select(columnOfInterests.map(c => col(c)):_*)
    .groupBy(dimensions.map(d => col(d)): _*)
    .agg(metrics.map( m => m -> "sum").toMap)
    .toDF(columnOfInterests:_*)    // that's the interesting part

The last line essentially renames every columns of the aggregated dataframe to the original fields, essentially changing sum(col2) and sum(col3) to simply col2 and col3.

In my case (using Laravel 5.3) adding only the following 2 middleware allowed me to access session data in my API routes:

• \App\Http\Middleware\EncryptCookies::class
• \Illuminate\Session\Middleware\StartSession::class

Whole declaration ($middlewareGroups in Kernel.php):

'api' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Session\Middleware\StartSession::class,
            'throttle:60,1',
            'bindings',
        ],

Static files should be served from resources, not from controller.

Spring Boot will automatically add static web resources located within any of the following directories:

/META-INF/resources/  
/resources/  
/static/  
/public/

This is a JQuery code for Preventing Submit

$('form').submit(function (e) {
            if (radioButtonValue !== "0") {
                e.preventDefault();
            }
        });

It's HTML character references for encoding a character by its decimal code point

Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe

With Bash (not POSIX) you can use process substitution to get the current line inside a variable. This enables you to use quotes to escape special characters:

while read line ; do cp "$line" ~/bar ; done < <(find . | grep foo)

1) Others (especially dirkgently) have noted that buffer needs to be allocated some memory space. For smallish values of N (say, N <= 4096), you can also allocate it on the stack:

#define BUFFER_SIZE 4096
char buffer[BUFFER_SIZE]

This saves you the worry of ensuring that you delete[] the buffer should an exception be thrown.

But remember that stacks are finite in size (so are heaps, but stacks are finiter), so you don't want to put too much there.

2) On a -1 return code, you should not simply return immediately (throwing an exception immediately is even more sketchy.) There are certain normal conditions that you need to handle, if your code is to be anything more than a short homework assignment. For example, EAGAIN may be returned in errno if no data is currently available on a non-blocking socket. Have a look at the man page for read(2).

Since it's a NodeList, not an Array, you shouldn't really be using brackets or casting to Array. The property way to get the first node is:

document.getElementsByName(id).item(0)

You can just cast that:

var script = <HTMLScriptElement> document.getElementsByName(id).item(0)

Or, extend NodeList:

interface HTMLScriptElementNodeList extends NodeList
{
    item(index: number): HTMLScriptElement;
}
var scripts = <HTMLScriptElementNodeList> document.getElementsByName('script'),
    script = scripts.item(0);

Adding to Alex's answer and simplifying it:

Objects are more strict with their use and hence gives the programmer more compile time "evaluation" power and hence in a lot of cases provide more "checking capability" and coould prevent any leaks, whereas any is a more generic term and a lot of compile time checks might hence be ignored.

My issue came from trying to disable the Maven nature from my project and then deleting the pom.xml file. This is bad, very bad, don't do this. If you do, change it back to a Maven project and hopefully you can either restore your old pom.xml file or create a new one. As soon as I did that, it worked again.

EDIT: I recently ran across this problem again and this time it was because I had duplicate libraries in my classpath. The one Maven added (which started with /M2_REPO/.... and then one I had added (which I should not have done). Even though Eclipse was reporting that it could not find the class, the actual problem was that I had given it two libraries with the same class and it didn't know which one to use. Once I removed the second reference, it worked.

I used the Visual Studio 2008 Uninstall tool and it worked fine for me.

You can use this tool to uninstall Visual Studio 2008 official release and Visual Studio 2008 Release candidate (Only English version).

Found here, on the MSDN Forum: MSDN forum topic.

I found this answer here

Be sure you run the tool with admin-rights.

is only the matter of finding the dom where you want to insert the the text.

DEMO jsfiddle

$().text(); 

change the call to ereg_replace to use preg_replace instead

Kotlin version:

Use these extensions with infix functions that simplify later calls

infix fun View.below(view: View) {
    (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.BELOW, view.id)
}

infix fun View.leftOf(view: View) {
    (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.LEFT_OF, view.id)
}

infix fun View.alightParentRightIs(aligned: Boolean) {
    val layoutParams = this.layoutParams as? RelativeLayout.LayoutParams
    if (aligned) {
        (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
    } else {
        (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, 0)
    }
    this.layoutParams = layoutParams
}

Then use them as infix functions calls:

view1 below view2
view1 leftOf view2
view1 alightParentRightIs true

Or you can use them as normal functions:

view1.below(view2)
view1.leftOf(view2)
view1.alightParentRightIs(true)

ng-click="$event.preventDefault()"

Another library-based option: use d3-time-format:

const formatter = d3.timeFormat('%U');
const weekNum = formatter(new Date());

Just use the name of the main folder which the .py file is in.

To count all occurrences, use -o. Try this:

echo afoobarfoobar | grep -o foo | wc -l

And man grep of course (:

Update

Some suggest to use just grep -co foo instead of grep -o foo | wc -l.

Don't.

This shortcut won't work in all cases. Man page says:

-c print a count of matching lines

Difference in these approaches is illustrated below:

1.

$ echo afoobarfoobar | grep -oc foo
1

As soon as the match is found in the line (a{foo}barfoobar) the searching stops. Only one line was checked and it matched, so the output is 1. Actually -o is ignored here and you could just use grep -c instead.

2.

$ echo afoobarfoobar | grep -o foo
foo
foo

$ echo afoobarfoobar | grep -o foo | wc -l
2

Two matches are found in the line (a{foo}bar{foo}bar) because we explicitly asked to find every occurrence (-o). Every occurence is printed on a separate line, and wc -l just counts the number of lines in the output.

You are using a function, which is marked as deleted.
Eg:

int doSomething( int ) = delete;

The =delete is a new feature of C++0x. It means the compiler should immediately stop compiling and complain "this function is deleted" once the user use such function.

If you see this error, you should check the function declaration for =delete.

To know more about this new feature introduced in C++0x, check this out.

Separate with commas:

http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name=Actor1&name=Actor2&name=Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name[0]=Actor1&name[1]=Actor2&name[2]=Actor3&startDate=20120101&endDate=20120505

Either way, your method signature needs to be:

@RequestMapping(value = "/GetJson", method = RequestMethod.GET) 
public void getJson(@RequestParam("name") String[] ticker, @RequestParam("startDate") String startDate, @RequestParam("endDate") String endDate) {
   //code to get results from db for those params.
 }

Just adding to the other excellent answers. Scala offers two often criticized symbolic operators, /: (foldLeft) and :\ (foldRight) operators, the first being right-associative. So the following three statements are the equivalent:

( 1 to 100 ).foldLeft( 0, _+_ )
( 1 to 100 )./:( 0 )( _+_ )
( 0 /: ( 1 to 100 ) )( _+_ )

As are these three:

( 1 to 100 ).foldRight( 0, _+_ )
( 1 to 100 ).:\( 0 )( _+_ )
( ( 1 to 100 ) :\ 0 )( _+_ )

When accessing the field value, pass the instance rather than null.

Why not use code generation here? Eclipse, for example, will generate a reasoble toString implementation for you.

The problem in my case was missing component declaration in the module, but even after adding the declaration the error persisted. I had stop the server and rebuild the entire project in VS Code for the error to go away.

Here is a solution for reading - not writing - the extended properties based on what I found on this page and at help with shell32 objects.

To be clear this is a hack. It looks like this code will still run on Windows 10 but will hit on some empty properties. Previous version of Windows should use:

        var i = 0;
        while (true)
        {
            ...
            if (String.IsNullOrEmpty(header)) break;
            ...
            i++;

On Windows 10 we assume that there are about 320 properties to read and simply skip the empty entries:

    private Dictionary<string, string> GetExtendedProperties(string filePath)
    {
        var directory = Path.GetDirectoryName(filePath);
        var shell = new Shell32.Shell();
        var shellFolder = shell.NameSpace(directory);
        var fileName = Path.GetFileName(filePath);
        var folderitem = shellFolder.ParseName(fileName);
        var dictionary = new Dictionary<string, string>();
        var i = -1;
        while (++i < 320)
        {
            var header = shellFolder.GetDetailsOf(null, i);
            if (String.IsNullOrEmpty(header)) continue;
            var value = shellFolder.GetDetailsOf(folderitem, i);
            if (!dictionary.ContainsKey(header)) dictionary.Add(header, value);
            Console.WriteLine(header +": " + value);
        }
        Marshal.ReleaseComObject(shell);
        Marshal.ReleaseComObject(shellFolder);
        return dictionary;
    }

As mentioned you need to reference the Com assembly Interop.Shell32.

If you get an STA related exception, you will find the solution here:

Exception when using Shell32 to get File extended properties

I have no idea what those properties names would be like on a foreign system and couldn't find information about which localizable constants to use in order to access the dictionary. I also found that not all the properties from the Properties dialog were present in the dictionary returned.

BTW this is terribly slow and - at least on Windows 10 - parsing dates in the string retrieved would be a challenge so using this seems to be a bad idea to start with.

On Windows 10 you should definitely use the Windows.Storage library which contains the SystemPhotoProperties, SystemMusicProperties etc. https://docs.microsoft.com/en-us/windows/uwp/files/quickstart-getting-file-properties

And finally, I posted a much better solution that uses WindowsAPICodePack there

MySQL prior to version 5 did not allow aggregate functions in ORDER BY clauses.

You can get around this limit with the deprecated syntax:

SELECT COUNT(id), `Tag` from `images-tags`
GROUP BY `Tag`
ORDER BY 1 DESC
LIMIT 20

1, since it's the first column you want to group on.

Use Java Source Attacher !

It does what eclipse should do - a right click context menu that says "Attach Java Source.

It automatically downloads the source for you and attaches it. I've only hit a couple libraries it doesn't know about and when that happens it lets you contribute the url back to the community so no one else will have a problem with that library.

To check if something does not exist in a string, you at least need to look at each character in a string. So even if you don't explicitly use a loop, it'll have the same efficiency. That being said, you can try using str.contains(""+char).

I'd recommend NetBeans 6.1 too. Very nice IDE and makes working with Ruby a pleasure.

Validate the INPUT.

$time = strtotime($_POST['dateFrom']);
if ($time) {
  $new_date = date('Y-m-d', $time);
  echo $new_date;
} else {
   echo 'Invalid Date: ' . $_POST['dateFrom'];
  // fix it.
}

In my case it was enough to split the text at every \n and then create a JLabel for every line:

JPanel panel = new JPanel(new GridLayout(0,1));
String[] lines = message.split("\n");
for (String line : lines) {
    JLabel label = new JLabel(line);
    panel.add(label);
}

I used above in a JOptionPane.showMessageDialog

Pasting the jar files in WebContent\WEB-INF\lib via the file system was the only way it worked for me.

They then appeared under the Deployed Resources and WebContent lib sub-folders.

When I looked, the build path had the jars in the Web App Libraries and everything built and ran fine.

just in case anyone is STILL stuck on this, despite the other answers, I solved this with:

$.datepicker.setDefaults($.datepicker.regional['en-GB']);

note the extra 'GB'. After that it worked fine.

I'm using IronPython here (same as .NET API) and reading the file as UTF-8 in order to properly handle the BOM fixed the problem for me:

xmlFile = Path.Combine(directory_str, 'file.xml')
doc = XPathDocument(XmlTextReader(StreamReader(xmlFile.ToString(), Encoding.UTF8)))

It would work as well with the XmlDocument:

doc = XmlDocument()
doc.Load(XmlTextReader(StreamReader(xmlFile.ToString(), Encoding.UTF8)))

I had problems with the other suggestions because I want to sometimes return values from my methods. If you try to use MethodInvoker with return values it doesn't seem to like it. So the solution I use is like this (very happy to hear a way to make this more succinct - I'm using c#.net 2.0):

    // Create delegates for the different return types needed.
    private delegate void VoidDelegate();
    private delegate Boolean ReturnBooleanDelegate();
    private delegate Hashtable ReturnHashtableDelegate();

    // Now use the delegates and the delegate() keyword to create 
    // an anonymous method as required

    // Here a case where there's no value returned:
    public void SetTitle(string title)
    {
        myWindow.Invoke(new VoidDelegate(delegate()
        {
            myWindow.Text = title;
        }));
    }

    // Here's an example of a value being returned
    public Hashtable CurrentlyLoadedDocs()
    {
        return (Hashtable)myWindow.Invoke(new ReturnHashtableDelegate(delegate()
        {
            return myWindow.CurrentlyLoadedDocs;
        }));
    }

Use Class instead of Interface that is what I discovered after all my research.

Why? A class alone is less code than a class-plus-interface. (anyway you may require a Class for data model)

Why? A class can act as an interface (use implements instead of extends).

Why? An interface-class can be a provider lookup token in Angular dependency injection.

from Angular Style Guide

Basically a Class can do all, what an Interface will do. So may never need to use an Interface.

TL;DR;

Set "Build Active Architecture Only (ONLY_ACTIVE_ARCH)" to Yes for your libraries/apps, even for release mode.

While trying to identify the root cause of the issue I realized some fun facts about Xcode 12.

1. Xcode 12 is actually the stepping stone for Apple Silicon which unfortunately is not yet available (when the answer was written). But with that platform we are gonna get arm64 based macOS where simulators will also run on arm64 architecture unlike the present Intel based x86_64 architecture.

2. Xcode usually depends on the "Run Destination" to build its libraries/apps. So when a simulator is chosen as the "Run Destination", it builds the app for available simulator architectures and when a device is chosen as the "Run Destination" it builds for the architecture that the device supports (arm*).

3. xcodebuild, in the Xcode 12+ build system considers arm64 as a valid architecture for simulator to support Apple Silicon. So when a simulator is chosen as the run destination, it can potentially try to compile/link your libs/apps against arm64 based simulators, as well. So it sends clang(++) some -target flag like arm64-apple-ios13.0-simulator in <architecture>-<os>-<sdk>-<destination> format and clang tries to build/link against arm64 based simulator that eventually fails on Intel based mac.

4. But xcodebuild tries this only for Release builds. Why? Because, "Build Active Architecture Only (ONLY_ACTIVE_ARCH)" build settings is usually set to "No" for the "Release" configuration only. And that means xcodebuild will try to build all architectural variants of your libs/apps for the selected run destination for release builds. And for the Simulator run destination, it will includes both x86_64 and arm64 now on, since arm64 in Xcode 12+ is also a supported architecture for simulators to support Apple Silicon.

Simply putting, Xcode will fail to build your app anytime it tries the command line, xcodebuild, (which defaults to release build, see the general tab of your project setting) or otherwise and tries to build all architectural variants supported by the run destination. So a simple workaround to this issue is to set "Build Active Architecture Only (ONLY_ACTIVE_ARCH)" to Yes in your libraries/apps, even for release mode.

If the libraries are included as Pods and you have access to .podspec you can simply set:

spec.pod_target_xcconfig = { 'ONLY_ACTIVE_ARCH' => 'YES' }

spec.user_target_xcconfig = { 'ONLY_ACTIVE_ARCH' => 'YES' } # not recommended

I personally don't like the second line since pods shouldn't pollute the target project and it could be overridden in the target settings, itself. So it should be the responsibility of the consumer project to override the setting by some means. However, this could be necessary for successful linting of podspecs.

However, if you don't have access to the .podspec, you can always update the settings during installation of the pods:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings["ONLY_ACTIVE_ARCH"] = "YES"
    end
  end
end

One thing I was concerned about that what will be the impact of this when we actually archive the libs/apps. During archiving apps usually take the "Release" configuration and since this will be creating a release build considering only the active architecture of the current run destination, with this approach, we may lose the slices for armv7, armv7s, etc from target build. However, I noticed the documentation says (highlighted in the attached picture) that this setting will be ignored when we choose "Generic iOS Device/Any Device" as the run destination, since it doesn't define any specific architecture. So I guess we should be good if we archive our app choosing that as a run destination.

Maybe too wordy but they may help give you ideas.

Try this, seems the uniq function needs a sorted list to work properly.

use strict;

# Helper function to remove duplicates in a list.
sub uniq {
  my %seen;
  grep !$seen{$_}++, @_;
}

my @teststrings = ("one", "two", "three", "one");

my @filtered = uniq @teststrings;
print "uniq: @filtered\n";
my @sorted = sort @teststrings;
print "sort: @sorted\n";
my @sortedfiltered = uniq sort @teststrings;
print "uniq sort : @sortedfiltered\n";

You may find it easier to loop over your array and build a new array out of the items you want to keep from the array than by trying to loop and splice as has been suggested, since modifying the length of the array while it is being looped over can introduce problems.

You could do something like this:

function removeFalsyElementsFromArray(someArray) {
    var newArray = [];
    for(var index = 0; index < someArray.length; index++) {
        if(someArray[index]) {
            newArray.push(someArray[index]);
        }
    }
    return newArray;
}

Actually here is a more generic solution:

function removeElementsFromArray(someArray, filter) {
    var newArray = [];
    for(var index = 0; index < someArray.length; index++) {
        if(filter(someArray[index]) == false) {
            newArray.push(someArray[index]);
        }
    }
    return newArray;
}

// then provide one or more filter functions that will 
// filter out the elements based on some condition:
function isNullOrUndefined(item) {
    return (item == null || typeof(item) == "undefined");
}

// then call the function like this:
var myArray = [1,2,,3,,3,,,,,,4,,4,,5,,6,,,,];
var results = removeElementsFromArray(myArray, isNullOrUndefined);

// results == [1,2,3,3,4,4,5,6]

You get the idea - you could then have other types of filter functions. Probably more than you need, but I was feeling generous... ;)

Note: If you just want to stop MySQL server, this might be helpful. In my case, it kept on restarting as soon as I killed the process using PID. Also brew stop command didn't work as I installed without using homebrew. Then I went to mac system preferences and we have MySQL installed there. Just open it and stop the MySQL server and you're done. Here in the screenshot, you can find MySQL in bottom of system preferences.

There are two ways to do this. One is very simple but unsafe:

Map<String, Object> map = new HashMap<String, Object>();
Map<String, String> newMap = new HashMap<String, String>((Map)map);  // unchecked warning

The other way has no compiler warnings and ensures type safety at runtime, which is more robust. (After all, you can't guarantee the original map contains only String values, otherwise why wouldn't it be Map<String, String> in the first place?)

Map<String, Object> map = new HashMap<String, Object>();
Map<String, String> newMap = new HashMap<String, String>();
@SuppressWarnings("unchecked") Map<String, Object> intermediate =
    (Map)Collections.checkedMap(newMap, String.class, String.class);
intermediate.putAll(map);

The simple reply is:

setTimeout(
    function () {
        x = 1;
    }, 1000);

The function above waits for 1 second (1000 ms) then sets x to 1. Obviously this is an example; you can do anything you want inside the anonymous function.

This suffices and stores the first line of filename in the variable $line:

read -r line < filename

I also like awk for this:

awk 'NR==1 {print; exit}' file

To store the line itself, use the var=$(command) syntax. In this case, line=$(awk 'NR==1 {print; exit}' file).

Or even sed:

sed -n '1p' file

With the equivalent line=$(sed -n '1p' file).

See a sample when we feed the read with seq 10, that is, a sequence of numbers from 1 to 10:

$ read -r line < <(seq 10) 
$ echo "$line"
1

$ line=$(awk 'NR==1 {print; exit}' <(seq 10))
$ echo "$line"
1

NOBODY above explained/clarified terms to a novice user. They get confused by the terms

.hg/hgrc -- this file is used for Repository, at local/workspace location / in actual repository's .hg folder.

~/.hgrc -- this file is different than the below one. this file resides at ~ or home directory.

myremote.xxxx=..... bb.xxxx=......

This is one of the lines under [auth] section/directive, while using mercurial keyring extension. Make sure the server name you put there, matches with what you use while doing "hg clone" otherwise keyring will say, user not found. bb or myremote in the line below, are "alias name" that you MUST give while doing "hg clone http:/.../../repo1 bb or myremote" otherwise, it wont work or you have to make sure your local repository's .hg/hgrc file contain same alias, ie (what you gave while doing hg clone .. as last parameter).

ex: If inside ~/.hgrc (user's home directory in Linux/Unix) or mercurial.ini in Windows at user's home directory, contains, the following line and if you do

`"hg clone http://.../.../reponame myremote"`

, then you'll never be prompted for user credentials more than once per http repo link. In ~/.hgrc under [extensions] a line for "mercurial_keyring = " or "hgext.mercurial_keyring = /path/to/your/mercurial_keyring.py" .. one of these lines should be there.

[auth]
myremote.schemes = http https
myremote.prefix = thsusncdnvm99/hg
myremote.username = c123456

I'm trying to find out how to set the PREFIX property so that user can clone or perform any Hg operations without username/password prompts and without worrying about what he mentioned in the http://..../... for servername while using the Hg repo link. It can be IP, servername or server's FQDN

You can manually insert http header to request:

HttpGet request = new HttpGet(...);
request.setHeader("Authorization", "Basic "+Base64.encodeBytes("login:password".getBytes()));

You can do this by thinking of it a little bit differently. Detect when the body is clicked (document.body.onclick - i.e. anything on the page) and then check if the element clicked (event.srcElement / e.target) has a class and that that class name is the one you want:

document.body.onclick = function(e) {   //when the document body is clicked
    if (window.event) {
        e = event.srcElement;           //assign the element clicked to e (IE 6-8)
    }
    else {
        e = e.target;                   //assign the element clicked to e
    }

    if (e.className && e.className.indexOf('someclass') != -1) {
        //if the element has a class name, and that is 'someclass' then...
        alert('hohoho');
    }
}

Or a more concise version of the above:

document.body.onclick= function(e){
   e=window.event? event.srcElement: e.target;
   if(e.className && e.className.indexOf('someclass')!=-1)alert('hohoho');
}

Here's a version of @Julian Mosquera's code that also supports a "fallback" field to use in case the primary field happens to be null or undefined:

yourApp.filter('orderObjectBy', function() {
  return function(items, field, fallback, reverse) {
    var filtered = [];
    angular.forEach(items, function(item) {
      filtered.push(item);
    });
    filtered.sort(function (a, b) {
      var af = a[field];
      if(af === undefined || af === null) { af = a[fallback]; }

      var bf = b[field];
      if(bf === undefined || bf === null) { bf = b[fallback]; }

      return (af > bf ? 1 : -1);
    });
    if(reverse) filtered.reverse();
    return filtered;
  };
});

int StringToWString(std::wstring &ws, const std::string &s)
{
    std::wstring wsTmp(s.begin(), s.end());

    ws = wsTmp;

    return 0;
}

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

I used accepted answer reference and would like to put an example, since Angular 2 documentation is very very hard to read, I hope this is easier:

1. Import NgZone:

   import { Component, NgZone } from '@angular/core';
   

2. Add it to your class constructor

   constructor(public zone: NgZone, ...args){}
   

3. Run code with zone.run:

   this.zone.run(() => this.donations = donations)
   

I fixed this problem by right clicking on tomcat server in Server tab and click "Clean Tomcat Work Directory"

In XAMPP Version 1.7.4 server does not have extension=php_openssl.dll line in php ini file. We have to add extension=php_openssl.dll in php.ini file

Run time permission creates a lot of boilerplate code in activity which is heavily coupled. To reduce code and make the thing easy, you can use Dexter library.

I have improved batch file with yes or no prompt. If user enter any character except y and n , then it will again prompt user for valid input. It Works for me.

    @echo off

    :ConfirmBox 
        set /P c= Are you sure want to contine (y/n)?

    if /I "%c%" EQU "Y" (
    goto :FnYes 
    ) else if /I "%c%" EQU "N" ( 
    goto :FnNo
    ) else ( 
    goto :InValid 
    )


:FnYes
     echo You have entered Y
     goto :END

:FnNo
     echo You have entered N
     goto :END

:InValid
     echo Invalid selection. Enter Y or N
     goto :ConfirmBox

:END
    pause
    exit  

/I in if condition will validate both lowercase and uppercase characters.

The short version is: The efficient way to use readlines() is to not use it. Ever.

I read some doc notes on readlines(), where people has claimed that this readlines() reads whole file content into memory and hence generally consumes more memory compared to readline() or read().

The documentation for readlines() explicitly guarantees that it reads the whole file into memory, and parses it into lines, and builds a list full of strings out of those lines.

But the documentation for read() likewise guarantees that it reads the whole file into memory, and builds a string, so that doesn't help.

On top of using more memory, this also means you can't do any work until the whole thing is read. If you alternate reading and processing in even the most naive way, you will benefit from at least some pipelining (thanks to the OS disk cache, DMA, CPU pipeline, etc.), so you will be working on one batch while the next batch is being read. But if you force the computer to read the whole file in, then parse the whole file, then run your code, you only get one region of overlapping work for the entire file, instead of one region of overlapping work per read.

You can work around this in three ways:

1. Write a loop around readlines(sizehint), read(size), or readline().
2. Just use the file as a lazy iterator without calling any of these.
3. mmap the file, which allows you to treat it as a giant string without first reading it in.

For example, this has to read all of foo at once:

with open('foo') as f:
    lines = f.readlines()
    for line in lines:
        pass

But this only reads about 8K at a time:

with open('foo') as f:
    while True:
        lines = f.readlines(8192)
        if not lines:
            break
        for line in lines:
            pass

And this only reads one line at a time—although Python is allowed to (and will) pick a nice buffer size to make things faster.

with open('foo') as f:
    while True:
        line = f.readline()
        if not line:
            break
        pass

And this will do the exact same thing as the previous:

with open('foo') as f:
    for line in f:
        pass

Meanwhile:

but should the garbage collector automatically clear that loaded content from memory at the end of my loop, hence at any instant my memory should have only the contents of my currently processed file right ?

Python doesn't make any such guarantees about garbage collection.

The CPython implementation happens to use refcounting for GC, which means that in your code, as soon as file_content gets rebound or goes away, the giant list of strings, and all of the strings within it, will be freed to the freelist, meaning the same memory can be reused again for your next pass.

However, all those allocations, copies, and deallocations aren't free—it's much faster to not do them than to do them.

On top of that, having your strings scattered across a large swath of memory instead of reusing the same small chunk of memory over and over hurts your cache behavior.

Plus, while the memory usage may be constant (or, rather, linear in the size of your largest file, rather than in the sum of your file sizes), that rush of mallocs to expand it the first time will be one of the slowest things you do (which also makes it much harder to do performance comparisons).

Putting it all together, here's how I'd write your program:

for filename in os.listdir(input_dir):
    with open(filename, 'rb') as f:
        if filename.endswith(".gz"):
            f = gzip.open(fileobj=f)
        words = (line.split(delimiter) for line in f)
        ... my logic ...  

Or, maybe:

for filename in os.listdir(input_dir):
    if filename.endswith(".gz"):
        f = gzip.open(filename, 'rb')
    else:
        f = open(filename, 'rb')
    with contextlib.closing(f):
        words = (line.split(delimiter) for line in f)
        ... my logic ...

This problem occurs due to missing import of FormsModule,ReactiveFormsModule .I also came with same problem. My case was diff. as i was working with modules.So i missed above imports in my parent modules though i had imported it into child modules,it wasn't working.

Then i imported it into my parent modules as below, and it worked!

import { ReactiveFormsModule,FormsModule  } from '@angular/forms';
import { AlertModule } from 'ngx-bootstrap';

         @NgModule({
          imports: [
            CommonModule,
            FormsModule,
            ReactiveFormsModule,
    ],
      declarations: [MyComponent]
    })

new answer (fast)

You can make bash do the math for you, and it works with milliseconds.

toSeconds() {
    awk -F: 'NF==3 { print ($1 * 3600) + ($2 * 60) + $3 } NF==2 { print ($1 * 60) + $2 } NF==1 { print 0 + $1 }' <<< $1
}

StartSeconds=$(toSeconds "45.5")
EndSeconds=$(toSeconds "1:00.5")
Duration=$(bc <<< "(${EndSeconds} + 0.01) - ${StartSeconds}" | awk '{ printf "%.4f", $0 }')
ffmpeg -ss $StartSeconds -i input.mpg -t $Duration output.mpg

This, like the old answer, will produce a 15 second clip. This method is ideal even when clipping from deep within a large file because seeking isn't disabled, unlike the old answer. And yes, I've verified it's frame perfect.

NOTE: The start-time is INCLUSIVE and the end-time is normally EXCLUSIVE, hence the +0.01, to make it inclusive.

If you use mpv you can enable millisecond timecodes in the OSD with --osd-fractions

old answer with explanation (slow)

To cut based on start and end time from the source video and avoid having to do math, specify the end time as the input option and the start time as the output option.

ffmpeg -t 1:00 -i input.mpg -ss 45 output.mpg

This will produce a 15 second cut from 0:45 to 1:00.

This is because when -ss is given as an output option, the discarded time is still included in the total time read from the input, which -t uses to know when to stop. Whereas if -ss is given as an input option, the start time is seeked and not counted, which is where the confusion comes from.

It's slower than seeking since the omitted segment is still processed before being discarded, but this is the only way to do it as far as I know. If you're clipping from deep within a large file, it's more prudent to just do the math and use -ss for the input.

For a <input type='text'> element:

input { font-size: 18px; }

or for a <textarea>:

textarea { font-size: 18px; }

or for a <select>:

select { font-size: 18px; }

you get the drift.

New since 1.8 is a List.sort() method instead of using the Collection.sort() so you directly call mylistcontainer.sort()

Here is a code snippet which demonstrates the List.sort() feature:

List<Fruit> fruits = new ArrayList<Fruit>();
fruits.add(new Fruit("Kiwi","green",40));
fruits.add(new Fruit("Banana","yellow",100));
fruits.add(new Fruit("Apple","mixed green,red",120));
fruits.add(new Fruit("Cherry","red",10));

// a) using an existing compareto() method
fruits.sort((Fruit f1,Fruit f2) -> f1.getFruitName().compareTo(f2.getFruitName()));
System.out.println("Using String.compareTo(): " + fruits);
//Using String.compareTo(): [Apple is: mixed green,red, Banana is: yellow, Cherry is: red, Kiwi is: green]

// b) Using a comparable class
fruits.sort((Fruit f1,Fruit f2) -> f1.compareTo(f2));  
System.out.println("Using a Comparable Fruit class (sort by color): " + fruits);
// Using a Comparable Fruit class (sort by color): [Kiwi is green, Apple is: mixed green,red, Cherry is: red, Banana is: yellow]

The Fruit class is:

public class Fruit implements Comparable<Fruit>
{
    private String name;
    private String color;
    private int quantity;

    public Fruit(String name,String color,int quantity)
    { this.name = name; this.color = color; this.quantity = quantity; }

    public String getFruitName() { return name; }        
    public String getColor() { return color; }  
    public int getQuantity() { return quantity; }

    @Override public final int compareTo(Fruit f) // sorting the color
    {
        return this.color.compareTo(f.color);
    }     
    @Override public String toString()
    {   
        return (name + " is: " + color);
    }
} // end of Fruit class   

.text-left {
  text-align: left;
}

.text-right {
  text-align: right;

.text-center {
  text-align: center;
}

bootstrap has added three css classes for text align.

Example query: SELECT TO_CHAR(TO_DATE('2017-08-23','YYYY-MM-DD'), 'MM/DD/YYYY') FROM dual;

I hope i am not too late, this solution here worked for me, i am using COMODO SSL, the above solutions seem invalid over time, my website lifetanstic.co.ke

Instead of contacting Comodo Support and gain a CA bundle file You can do the following:

When You get your new SSL cert from Comodo (by mail) they have a zip file attached. You need to unzip the zip-file and open the following files in a text editor like notepad:

AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt

Then copy the text of each ".crt" file and paste the texts above eachother in the "Certificate Authority Bundle (optional)" field.

After that just add the SSL cert as usual in the "Certificate" field and click at "Autofil by Certificate" button and hit "Install".

Inspired by this gist: https://gist.github.com/ipedrazas/6d6c31144636d586dcc3

This is how to retrieve a Column Name from a DataColumn:

MyDataTable.Columns(1).ColumnName 

To get the name of all DataColumns within your DataTable:

Dim name(DT.Columns.Count) As String
Dim i As Integer = 0
For Each column As DataColumn In DT.Columns
  name(i) = column.ColumnName
  i += 1
Next

References

• Data Table (MSDN)
• Data Column (MSDN)

You can do something like req.param('tagId')

Use SimpleDateFormat#format:

DateFormat originalFormat = new SimpleDateFormat("MMMM dd, yyyy", Locale.ENGLISH);
DateFormat targetFormat = new SimpleDateFormat("yyyyMMdd");
Date date = originalFormat.parse("August 21, 2012");
String formattedDate = targetFormat.format(date);  // 20120821

Also note that parse takes a String, not a Date object, which is already parsed.

Yes, in VS2010 they changed this behavior somewhy.
Open your project and navigate to the following menu: Project -> YourProjectName Properties -> Configuration Properties -> Linker -> System. There in the field SubSystem use the drop-down to select Console (/SUBSYSTEM:CONSOLE) and apply the change.
"Start without debugging" should do the right thing now.

Or, if you write in C++ or in C, put

system("pause");

at the end of your program, then you'll get "Press any key to continue..." even when running in debug mode.

I recommend using json format, it's easier for parsing

ffprobe -i your-input-file.mp4 -v quiet -print_format json -show_format -show_streams -hide_banner

you can find the duration information in format section, works both for video and audio

The easiest way to implement this behaviour is by calling the pauseVideo and playVideo methods, when necessary. Inspired by the result of my previous answer, I have written a pluginless function to achieve the desired behaviour.

The only adjustments:

• I have added a function, toggleVideo
• I have added ?enablejsapi=1 to YouTube's URL, to enable the feature

Demo: http://jsfiddle.net/ZcMkt/
Code:

<script>
function toggleVideo(state) {
    // if state == 'hide', hide. Else: show video
    var div = document.getElementById("popupVid");
    var iframe = div.getElementsByTagName("iframe")[0].contentWindow;
    div.style.display = state == 'hide' ? 'none' : '';
    func = state == 'hide' ? 'pauseVideo' : 'playVideo';
    iframe.postMessage('{"event":"command","func":"' + func + '","args":""}', '*');
}
</script>

<p><a href="javascript:;" onClick="toggleVideo();">Click here</a> to see my presenting showreel, to give you an idea of my style - usually described as authoritative, affable and and engaging.</p>

<!-- popup and contents -->
<div id="popupVid" style="position:absolute;left:0px;top:87px;width:500px;background-color:#D05F27;height:auto;display:none;z-index:200;">
   <iframe width="500" height="315" src="http://www.youtube.com/embed/T39hYJAwR40?enablejsapi=1" frameborder="0" allowfullscreen></iframe>
   <br /><br />
   <a href="javascript:;" onClick="toggleVideo('hide');">close</a>

For anyone looking for a UI option using IIS Manager.

1. Open the Website in IIS Manager
2. Go To Request Filtering and open the Request Filtering Window.
3. Go to Verbs Tab and Add HTTP Verbs to "Allow Verb..." or "Deny Verb...". This allow to add the HTTP Verbs in the "Deny Verb.." Collection.

Request Filtering Window in IIS Manager

Add Verb... or Deny Verb...

Maybe map the share as a network drive and then do

git clone Z:\

Mostly just a guess; I always do this stuff using ssh. Following that suggstion of course will mean that you'll need to have that drive mapped every time you push/pull to/from the laptop. I'm not sure how you rig up ssh to work under windows but if you're going to be doing this a lot it might be worth investigating.
