if you use pg_dump with -Fp to backup in plain text format, use following command:

cat db.txt | psql dbname

to copy all data to your database with name dbname

I had the same issue "Cannot create a connection to data source...Login failed for user.." on Windows 8.1, SQL Server 2014 Developer Edition and Visual Studio 2013 Pro. All solutions offered above by other Stackoverflow Community members did not work for me.

So, I did the next steps (running all Windows applications as Administrator):

1. VS2013 SSRS: I converted my Data Source to Shared Data Source (.rds) with Windows Authentication (Integrated Security) on the Right Pane "Solution Explorer".

2. Original (non-shared) Data Source (on the Left Pane "Report Data") got "Don't Use Credentials".

3. On the Project Properties, I set for "Deployment" "Overwrite DataSources" to "True" and redeployed the Project.

After that, I could run my report without further requirements to enter Credentials. All Shared DataSources were deployed in a separate Directory "DataSources".

Well, I'd say it depends what you want to see in the logs, doesn't it? If you're happy with what ex.Message provides, use that. Otherwise, use ex.toString() or even log the stack trace.

ALTER TABLE `MY_TABLE` ADD COLUMN `STAGE` INTEGER UNSIGNED NOT NULL AFTER `PREV_COLUMN`;

Actually, using read.csv() to read a file with text content is not a good idea, disable the quote as set quote="" is only a temporary solution, it only worked with Separate quotation marks. There are other reasons would cause the warning, such as some special characters.

The permanent solution(using read.csv()), finding out what those special characters are and use a regular expression to eliminate them is an idea.

Have you ever think of installing the package {data.table} and use fread() to read the file. it is much faster and would not bother you with this EOF warning. Note that the file it loads it will be stored as a data.table object but not a data.frame object. The class data.table has many good features, but anyway, you can transform it using as.data.frame() if needed.

hr
{
  background-color: #123455;
}

the background is the one you should try to change

You can also work with the borders color. i am not sure i think there are crossbrowser issues with this. you should test it in differrent browsers

Should be:

curl --cert certificate_file.pem:password https://www.example.com/some_protected_page

To fix your code you can simply change [Cov] to Cov.values, the first parameter of pd.DataFrame will become a multi-dimensional numpy array:

Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')

But the smartest solution still is use pd.read_excel with header=None and names=columns_list.

Since php7, there is the random_bytes functions. https://www.php.net/manual/ru/function.random-bytes.php So you can generate a random string like that

<?php
$bytes = random_bytes(5);
var_dump(bin2hex($bytes));
?>

The following should work as it calculates difference between DATE and UTCDATE for the server you are running and uses that offset to calculate the UTC equivalent of any date you pass to it. In my example, I am trying to convert UTC equivalent for '1-nov-2012 06:00' in Adelaide, Australia where UTC offset is -630 minutes, which when added to any date will result in UTC equivalent of any local date.

select DATEADD(MINUTE, DATEDIFF(MINUTE, GETDATE(), GETUTCDATE()), '1-nov-2012 06:00')

Application Private Data files are stored within <internal_storage>/data/data/<package>

Files being stored in the internal storage can be accessed with openFileOutput() and openFileInput()

When those files are created as MODE_PRIVATE it is not possible to see/access them within another application such as a FileManager.

Try edtFTPj/PRO, a mature, robust SFTP client library that supports connection pools and asynchronous operations. Also supports FTP and FTPS so all bases for secure file transfer are covered.

ProgressBar is very simple and easy to use, i am intending to make this same as simple progress dialog. first step is that you can make xml layout of the dialog that you want to show, let say we name this layout

layout_loading_dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="20dp">
    <ProgressBar
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <TextView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="4"
        android:gravity="center"
        android:text="Please wait! This may take a moment." />
</LinearLayout>

next step is create AlertDialog which will show this layout with ProgressBar

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setCancelable(false); // if you want user to wait for some process to finish,
builder.setView(R.layout.layout_loading_dialog);
AlertDialog dialog = builder.create();

now all that is left is to show and hide this dialog in our click events like this

dialog.show(); // to show this dialog
dialog.dismiss(); // to hide this dialog

and thats it, it should work, as you can see it is farely simple and easy to implement ProgressBar instead of ProgressDialog. now you can show/dismiss this dialog box in either Handler or ASyncTask, its up to your need

It depends on which version of Oracle? Older versions require exp (export), newer versions use expdp (data pump); exp was deprecated but still works most of the time.

Before starting, note that Data Pump exports to the server-side Oracle "directory", which is an Oracle symbolic location mapped in the database to a physical location. There may be a default directory (DATA_PUMP_DIR), check by querying DBA_DIRECTORIES:

  SQL> select * from dba_directories;

... and if not, create one

  SQL> create directory DATA_PUMP_DIR as '/oracle/dumps';
  SQL> grant all on directory DATA_PUMP_DIR to myuser;    -- DBAs dont need this grant

Assuming you can connect as the SYSTEM user, or another DBA, you can export any schema like so, to the default directory:

 $ expdp system/manager schemas=user1 dumpfile=user1.dpdmp

Or specifying a specific directory, add directory=<directory name>:

 C:\> expdp system/manager schemas=user1 dumpfile=user1.dpdmp directory=DUMPDIR

With older export utility, you can export to your working directory, and even on a client machine that is remote from the server, using:

 $ exp system/manager owner=user1 file=user1.dmp

Make sure the export is done in the correct charset. If you haven't setup your environment, the Oracle client charset may not match the DB charset, and Oracle will do charset conversion, which may not be what you want. You'll see a warning, if so, then you'll want to repeat the export after setting NLS_LANG environment variable so the client charset matches the database charset. This will cause Oracle to skip charset conversion.

Example for American UTF8 (UNIX):

 $ export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

Windows uses SET, example using Japanese UTF8:

 C:\> set NLS_LANG=Japanese_Japan.AL32UTF8

More info on Data Pump here: http://docs.oracle.com/cd/B28359_01/server.111/b28319/dp_export.htm#g1022624

<init-param> and <context-param> are static parameters which are stored in web.xml file. If you have any data which doesn't change frequently you can store it in one of them.

If you want to store particular data which is confined to a particular servlet scope, then you can use <init-param> .Anything you declare inside <init-param> is only accessible only for that particular servlet.The init-param is declared inside the <servlet> tag.

<servlet>
     <display-name>HelloWorldServlet</display-name>
     <servlet-name>HelloWorldServlet</servlet-name>
     <init-param>
         <param-name>Greetings</param-name>
         <param-value>Hello</param-value>
     </init-param>
</servlet>

and you can access those parameters in the servlet as follows:

out.println(getInitParameter("Greetings"));

If you want to store data which is common for whole application and if it doesn't change frequently you can use <context-param> instead of servletContext.setAttribute() method of the application context. For more information regarding usage of <context-param> VS ServletContext.setAttribute() have a look at this question. context-param are declared under the tag web-app. You can declare and access the <context-param> as follows

<web-app>
    <context-param>
        <param-name>Country</param-name>
        <param-value>India</param-value>
    </context-param>
    <context-param>
        <param-name>Age</param-name>
        <param-value>24</param-value>
    </context-param>
</web-app>

Usage in the application either in a JSP or Servlet

getServletContext().getInitParameter("Country");
getServletContext().getInitParameter("Age");

Consider the signal() function from the C standard:

extern void (*signal(int, void(*)(int)))(int);

Perfectly obscurely obvious - it's a function that takes two arguments, an integer and a pointer to a function that takes an integer as an argument and returns nothing, and it (signal()) returns a pointer to a function that takes an integer as an argument and returns nothing.

If you write:

typedef void (*SignalHandler)(int signum);

then you can instead declare signal() as:

extern  SignalHandler signal(int signum, SignalHandler handler);

This means the same thing, but is usually regarded as somewhat easier to read. It is clearer that the function takes an int and a SignalHandler and returns a SignalHandler.

It takes a bit of getting used to, though. The one thing you can't do, though is write a signal handler function using the SignalHandler typedef in the function definition.

I'm still of the old-school that prefers to invoke a function pointer as:

(*functionpointer)(arg1, arg2, ...);

Modern syntax uses just:

functionpointer(arg1, arg2, ...);

I can see why that works - I just prefer to know that I need to look for where the variable is initialized rather than for a function called functionpointer.

Sam commented:

I have seen this explanation before. And then, as is the case now, I think what I didn't get was the connection between the two statements:

    extern void (*signal(int, void()(int)))(int);  /*and*/

    typedef void (*SignalHandler)(int signum);
    extern SignalHandler signal(int signum, SignalHandler handler);

Or, what I want to ask is, what is the underlying concept that one can use to come up with the second version you have? What is the fundamental that connects "SignalHandler" and the first typedef? I think what needs to be explained here is what is typedef is actually doing here.

Let's try again. The first of these is lifted straight from the C standard - I retyped it, and checked that I had the parentheses right (not until I corrected it - it is a tough cookie to remember).

First of all, remember that typedef introduces an alias for a type. So, the alias is SignalHandler, and its type is:

a pointer to a function that takes an integer as an argument and returns nothing.

The 'returns nothing' part is spelled void; the argument that is an integer is (I trust) self-explanatory. The following notation is simply (or not) how C spells pointer to function taking arguments as specified and returning the given type:

type (*function)(argtypes);

After creating the signal handler type, I can use it to declare variables and so on. For example:

static void alarm_catcher(int signum)
{
    fprintf(stderr, "%s() called (%d)\n", __func__, signum);
}

static void signal_catcher(int signum)
{
    fprintf(stderr, "%s() called (%d) - exiting\n", __func__, signum);
    exit(1);
}

static struct Handlers
{
    int              signum;
    SignalHandler    handler;
} handler[] =
{
    { SIGALRM,   alarm_catcher  },
    { SIGINT,    signal_catcher },
    { SIGQUIT,   signal_catcher },
};

int main(void)
{
    size_t num_handlers = sizeof(handler) / sizeof(handler[0]);
    size_t i;

    for (i = 0; i < num_handlers; i++)
    {
        SignalHandler old_handler = signal(handler[i].signum, SIG_IGN);
        if (old_handler != SIG_IGN)
            old_handler = signal(handler[i].signum, handler[i].handler);
        assert(old_handler == SIG_IGN);
    }

    ...continue with ordinary processing...

    return(EXIT_SUCCESS);
}

^{Please note How to avoid using printf() in a signal handler?}

So, what have we done here - apart from omit 4 standard headers that would be needed to make the code compile cleanly?

The first two functions are functions that take a single integer and return nothing. One of them actually doesn't return at all thanks to the exit(1); but the other does return after printing a message. Be aware that the C standard does not permit you to do very much inside a signal handler; POSIX is a bit more generous in what is allowed, but officially does not sanction calling fprintf(). I also print out the signal number that was received. In the alarm_handler() function, the value will always be SIGALRM as that is the only signal that it is a handler for, but signal_handler() might get SIGINT or SIGQUIT as the signal number because the same function is used for both.

Then I create an array of structures, where each element identifies a signal number and the handler to be installed for that signal. I've chosen to worry about 3 signals; I'd often worry about SIGHUP, SIGPIPE and SIGTERM too and about whether they are defined (#ifdef conditional compilation), but that just complicates things. I'd also probably use POSIX sigaction() instead of signal(), but that is another issue; let's stick with what we started with.

The main() function iterates over the list of handlers to be installed. For each handler, it first calls signal() to find out whether the process is currently ignoring the signal, and while doing so, installs SIG_IGN as the handler, which ensures that the signal stays ignored. If the signal was not previously being ignored, it then calls signal() again, this time to install the preferred signal handler. (The other value is presumably SIG_DFL, the default signal handler for the signal.) Because the first call to 'signal()' set the handler to SIG_IGN and signal() returns the previous error handler, the value of old after the if statement must be SIG_IGN - hence the assertion. (Well, it could be SIG_ERR if something went dramatically wrong - but then I'd learn about that from the assert firing.)

The program then does its stuff and exits normally.

Note that the name of a function can be regarded as a pointer to a function of the appropriate type. When you do not apply the function-call parentheses - as in the initializers, for example - the function name becomes a function pointer. This is also why it is reasonable to invoke functions via the pointertofunction(arg1, arg2) notation; when you see alarm_handler(1), you can consider that alarm_handler is a pointer to the function and therefore alarm_handler(1) is an invocation of a function via a function pointer.

So, thus far, I've shown that a SignalHandler variable is relatively straight-forward to use, as long as you have some of the right type of value to assign to it - which is what the two signal handler functions provide.

Now we get back to the question - how do the two declarations for signal() relate to each other.

Let's review the second declaration:

 extern SignalHandler signal(int signum, SignalHandler handler);

If we changed the function name and the type like this:

 extern double function(int num1, double num2);

you would have no problem interpreting this as a function that takes an int and a double as arguments and returns a double value (would you? maybe you'd better not 'fess up if that is problematic - but maybe you should be cautious about asking questions as hard as this one if it is a problem).

Now, instead of being a double, the signal() function takes a SignalHandler as its second argument, and it returns one as its result.

The mechanics by which that can also be treated as:

extern void (*signal(int signum, void(*handler)(int signum)))(int signum);

are tricky to explain - so I'll probably screw it up. This time I've given the parameters names - though the names aren't critical.

In general, in C, the declaration mechanism is such that if you write:

type var;

then when you write var it represents a value of the given type. For example:

int     i;            // i is an int
int    *ip;           // *ip is an int, so ip is a pointer to an integer
int     abs(int val); // abs(-1) is an int, so abs is a (pointer to a)
                      // function returning an int and taking an int argument

In the standard, typedef is treated as a storage class in the grammar, rather like static and extern are storage classes.

typedef void (*SignalHandler)(int signum);

means that when you see a variable of type SignalHandler (say alarm_handler) invoked as:

(*alarm_handler)(-1);

the result has type void - there is no result. And (*alarm_handler)(-1); is an invocation of alarm_handler() with argument -1.

So, if we declared:

extern SignalHandler alt_signal(void);

it means that:

(*alt_signal)();

represents a void value. And therefore:

extern void (*alt_signal(void))(int signum);

is equivalent. Now, signal() is more complex because it not only returns a SignalHandler, it also accepts both an int and a SignalHandler as arguments:

extern void (*signal(int signum, SignalHandler handler))(int signum);

extern void (*signal(int signum, void (*handler)(int signum)))(int signum);

If that still confuses you, I'm not sure how to help - it is still at some levels mysterious to me, but I've grown used to how it works and can therefore tell you that if you stick with it for another 25 years or so, it will become second nature to you (and maybe even a bit quicker if you are clever).

I threw together a small test implementation of this. The basic idea is to call format and pass in the format string, and a map of objects, and the names that they have locally.

The output of the following is:

My dog is named fido, and Jane Doe owns him.

public class StringFormatter {

    private static final String fieldStart = "\\$\\{";
    private static final String fieldEnd = "\\}";

    private static final String regex = fieldStart + "([^}]+)" + fieldEnd;
    private static final Pattern pattern = Pattern.compile(regex);

    public static String format(String format, Map<String, Object> objects) {
        Matcher m = pattern.matcher(format);
        String result = format;
        while (m.find()) {
            String[] found = m.group(1).split("\\.");
            Object o = objects.get(found[0]);
            Field f = o.getClass().getField(found[1]);
            String newVal = f.get(o).toString();
            result = result.replaceFirst(regex, newVal);
        }
        return result;
    }

    static class Dog {
        public String name;
        public String owner;
        public String gender;
    }

    public static void main(String[] args) {
        Dog d = new Dog();
        d.name = "fido";
        d.owner = "Jane Doe";
        d.gender = "him";
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("d", d);
        System.out.println(
           StringFormatter.format(
                "My dog is named ${d.name}, and ${d.owner} owns ${d.gender}.", 
                map));
    }
}

Note: This doesn't compile due to unhandled exceptions. But it makes the code much easier to read.

Also, I don't like that you have to construct the map yourself in the code, but I don't know how to get the names of the local variables programatically. The best way to do it, is to remember to put the object in the map as soon as you create it.

The following example produces the results that you want from your example:

public static void main(String[] args) {
    Map<String, Object> map = new HashMap<String, Object>();
    Site site = new Site();
    map.put("site", site);
    site.name = "StackOverflow.com";
    User user = new User();
    map.put("user", user);
    user.name = "jjnguy";
    System.out.println(
         format("Hello ${user.name},\n\tWelcome to ${site.name}. ", map));
}

_{I should also mention that I have no idea what Velocity is, so I hope this answer is relevant.}

Technically, no. But what you can do is use a font size that is as tall as you would like the stretched font to be, and then condense it horizontally with font-stretch.

For the the accepted answer of @Joseph Silber is not working, because indexOf returns -1. This is probably because Angular adds an hashkey, which is different for my $scope.items[0] and my item. I tried to resolve this with the angular.toJson() function, but it did not work :(

Ah, I found out the reason... I use a chunk method to create two columns in my table by watching my $scope.items. Sorry!

This is a perfect use-case for DISTINCT ON - a Postgres specific extension of the standard DISTINCT:

SELECT DISTINCT ON (category)
       id  -- , category, date  -- any other column (expression) from the same row
FROM   tbl
ORDER  BY category, date DESC;

Careful with descending sort order. If the column can be NULL, you may want to add NULLS LAST:

• Sort by column ASC, but NULL values first?

DISTINCT ON is simple and fast. Detailed explanation in this related answer:

• Select first row in each GROUP BY group?

For big tables with many rows per category consider an alternative approach:

• Optimize GROUP BY query to retrieve latest row per user
• Optimize groupwise maximum query

Lots of answers available, speed is irrelevant for such small functions unless you are calling them a few hundred thousand times in a short period of time. For me, a regular expression is best, but keep it in a closure so you don't build it every time:

Simple version:

function vowelTest(s) {
  return (/^[aeiou]$/i).test(s);
}

More efficient version:

var vowelTest = (function() {
  var re = /^[aeiou]$/i;
  return function(s) {
    return re.test(s);
  }
})();

Returns true if s is a single vowel (upper or lower case) and false for everything else.

Locking a file is usually a platform-specific operation, so you may need to allow for the possibility of running on different operating systems. For example:

import os

def my_lock(f):
    if os.name == "posix":
        # Unix or OS X specific locking here
    elif os.name == "nt":
        # Windows specific locking here
    else:
        print "Unknown operating system, lock unavailable"

it should work

example_string = '0, 0, 0, 11, 0, 0, 0, 0, 0, 19, 0, 9, 0, 0, 0, 0, 0, 0, 11'
example_list = [int(k) for k in example_string.split(',')]

Localstorage is attached on the global window. When we log localstorage in the chrome devtools we see that it has the following APIs:

We can use the following API's for deleting items:

1. localStorage.clear(): Clears the whole localstorage
2. localStorage.removeItem('myItem'): To remove individual items

Here is the script... 

#!/bin/bash
echo "Please enter username:"
read username
echo "Please enter the new password:"
read -s password1
echo "Please repeat the new password:"
read -s password2

# Check both passwords match
if [ $password1 != $password2 ]; then
echo "Passwords do not match"
 exit    
fi

# Does User exist?
id $username &> /dev/null
if [ $? -eq 0 ]; then
echo "$username exists... changing password."
else
echo "$username does not exist - Password could not be updated for $username"; exit 
fi

# Change password
echo -e "$password1\n$password1" | passwd $username

Float is Approximate-number data type, which means that not all values in the data type range can be represented exactly.

Decimal/Numeric is Fixed-Precision data type, which means that all the values in the data type range can be represented exactly with precision and scale. You can use decimal for money saving.

Converting from Decimal or Numeric to float can cause some loss of precision. For the Decimal or Numeric data types, SQL Server considers each specific combination of precision and scale as a different data type. DECIMAL(2,2) and DECIMAL(2,4) are different data types. This means that 11.22 and 11.2222 are different types though this is not the case for float. For FLOAT(6) 11.22 and 11.2222 are same data types.

You can also use money data type for saving money. This is native data type with 4 digit precision for money. Most experts prefers this data type for saving money.

Just to add to the answers, App Server Apache Geronimo 3.0 uses Tomcat 7 as the web server, and in that environment the file server.xml is located at <%GERONIMO_HOME%>/var/catalina/server.xml.

The configuration does take effect even when the Geronimo Console at Application Server->WebServer->TomcatWebConnector->maxPostSize still displays 2097152 (the default value)

You certainly are able to have multiple CTEs in a single query expression. You just need to separate them with a comma. Here is an example. In the example below, there are two CTEs. One is named CategoryAndNumberOfProducts and the second is named ProductsOverTenDollars.

WITH CategoryAndNumberOfProducts (CategoryID, CategoryName, NumberOfProducts) AS
(
   SELECT
      CategoryID,
      CategoryName,
      (SELECT COUNT(1) FROM Products p
       WHERE p.CategoryID = c.CategoryID) as NumberOfProducts
   FROM Categories c
),

ProductsOverTenDollars (ProductID, CategoryID, ProductName, UnitPrice) AS
(
   SELECT
      ProductID,
      CategoryID,
      ProductName,
      UnitPrice
   FROM Products p
   WHERE UnitPrice > 10.0
)

SELECT c.CategoryName, c.NumberOfProducts,
      p.ProductName, p.UnitPrice
FROM ProductsOverTenDollars p
   INNER JOIN CategoryAndNumberOfProducts c ON

The DatatypeConverter solution doesn't work in all VMs. The following works for me:

javax.xml.datatype.DatatypeFactory.newInstance().newXMLGregorianCalendar("2011-01-01Z").toGregorianCalendar().getTime()

I've found that joda does not work out of the box (specifically for the example I gave above with the timezone on a date, which should be valid)

A simpler approach to this

At the beginning of column B, type

=UNIQUE(A:A)

Then in column C, use

=COUNTIF(A:A, B1)

and copy them in all row column C.

Edit: If that doesn't work for you, try using semicolon instead of comma:

=COUNTIF(A:A; B1)

Quite a bit late, but a duplicate answer that doesn't require altering the padding or adding extra divs can be found here: Have an issue with box-shadow Inset bottom only. It says, "Use a negative value for the fourth length which defines the spread distance. This is often overlooked, but supported by all major browsers"

From the answerer's fiddle:

box-shadow: inset 0 -10px 10px -10px #000000;

In short, I don't have the implementation, but the explanation.

Google did not make offline speech recognition available to third party apps. Offline recognition is only accessable via the keyboard. Ben Randall (the developer of utter!) explains his workaround in an article at Android Police:

I had implemented my own keyboard and was switching between Google Voice Typing and the users default keyboard with an invisible edit text field and transparent Activity to get the input. Dirty hack!

This was the only way to do it, as offline Voice Typing could only be triggered by an IME or a system application (that was my root hack) . The other type of recognition API … didn't trigger it and just failed with a server error. … A lot of work wasted for me on the workaround! But at least I was ready for the implementation...

From Utter! Claims To Be The First Non-IME App To Utilize Offline Voice Recognition In Jelly Bean

This prints all elements that contain sub:

for s in filter (lambda x: sub in x, list): print (s)

Combining the following sources, the following code works on Windows, Linux and macOS using just the platform and os modules:

• cantdutchthis' answer for the mac command
• natka_m's comment for the Ubuntu command
• BananaAcid's answer for the Windows command
• Louis Brandy's answer for how to detect the OS
• nc3b's answer for how to detect the Linux distribution

tx = input("Text to say >>> ")
tx = repr(tx)

import os
import platform

syst = platform.system()
if syst == 'Linux' and platform.linux_distribution()[0] == "Ubuntu":
    os.system('spd-say %s' % tx)
elif syst == 'Windows':
    os.system('PowerShell -Command "Add-Type –AssemblyName System.Speech; (New-Object System.Speech.Synthesis.SpeechSynthesizer).Speak(%s);"' % tx)
elif syst == 'Darwin':
    os.system('say %s' % tx)
else:
    raise RuntimeError("Operating System '%s' is not supported" % syst)

Here's the source code of an HttpHandler which does that, maybe it'll help you

Utility method which you call by passing navigationController and color which you like to set on navigation bar. For transparent you can use clearColor of UIColor class.

For objective c -

+ (void)setNavigationBarColor:(UINavigationController *)navigationController 
                               color:(UIColor*) color {
   [navigationController setNavigationBarHidden:false animated:false];
   [navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
   [navigationController.navigationBar setShadowImage:[UIImage new]];
   [navigationController.navigationBar setTranslucent:true];
   [navigationController.view setBackgroundColor:color];
   [navigationController.navigationBar setBackgroundColor:color];
}

For Swift 3.0 -

class func setNavigationBarColor(navigationController : UINavigationController?, 
                                 color : UIColor) {
    navigationController?.setNavigationBarHidden(false, animated: false)
    navigationController?.navigationBar .setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
    navigationController?.navigationBar.shadowImage = UIImage()
    navigationController?.navigationBar.translucent = true
    navigationController?.view.backgroundColor = color
    navigationController?.navigationBar.backgroundColor =  color
}

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

Old question but I came up with a definitive answer with an example. Can't hurt to keep questions fresh as I had this same problem and didn't find a clear answer. The key is to make sure you have numpy imported, and then run the isinstance bool. While this may seem simple, if you are doing some computations across different data types, this small check can serve as a quick test before your start some numpy vectorized operation.

##################
# important part!
##################

import numpy as np

####################
# toy array for demo
####################

arr = np.asarray(range(1,100,2))

########################
# The instance check
######################## 

isinstance(arr,np.ndarray)

Another easier way to do it is to upload your file to google sheets, then add a pivot, for the columns and rows select the same as you would with Excel, however, for values select Calculated Field and then in the formula type in =

If you look at the Android resources, the seek bar actually use images.

You have to make a drawable which is transparent on top and bottom for say 10px and the center 5px line is visible.

Refer attached image. You need to convert it into a NinePatch.

Incase their is local uncommitted changes and avoid merge conflict while pulling.

I had an issue with the same thing. ChromeOptions is very weird because it's not integrated with the desiredcapabilities like you would think. I forget the exact details, but basically ChromeOptions will reset to default certain values based on whether you did or did not pass a desired capabilities dict.

I did the following monkey-patch that allows me to specify my own dict without worrying about the complications of ChromeOptions

change the following code in /selenium/webdriver/chrome/webdriver.py:

def __init__(self, executable_path="chromedriver", port=0,
             chrome_options=None, service_args=None,
             desired_capabilities=None, service_log_path=None, skip_capabilities_update=False):
    """
    Creates a new instance of the chrome driver.

    Starts the service and then creates new instance of chrome driver.

    :Args:
     - executable_path - path to the executable. If the default is used it assumes the executable is in the $PATH
     - port - port you would like the service to run, if left as 0, a free port will be found.
     - desired_capabilities: Dictionary object with non-browser specific
       capabilities only, such as "proxy" or "loggingPref".
     - chrome_options: this takes an instance of ChromeOptions
    """
    if chrome_options is None:
        options = Options()
    else:
        options = chrome_options

    if skip_capabilities_update:
        pass
    elif desired_capabilities is not None:
        desired_capabilities.update(options.to_capabilities())
    else:
        desired_capabilities = options.to_capabilities()

    self.service = Service(executable_path, port=port,
        service_args=service_args, log_path=service_log_path)
    self.service.start()

    try:
        RemoteWebDriver.__init__(self,
            command_executor=self.service.service_url,
            desired_capabilities=desired_capabilities)
    except:
        self.quit()
        raise 
    self._is_remote = False

all that changed was the "skip_capabilities_update" kwarg. Now I just do this to set my own dict:

capabilities = dict( DesiredCapabilities.CHROME )

if not "chromeOptions" in capabilities:
    capabilities['chromeOptions'] = {
        'args' : [],
        'binary' : "",
        'extensions' : [],
        'prefs' : {}
    }

capabilities['proxy'] = {
    'httpProxy' : "%s:%i" %(proxy_address, proxy_port),
    'ftpProxy' : "%s:%i" %(proxy_address, proxy_port),
    'sslProxy' : "%s:%i" %(proxy_address, proxy_port),
    'noProxy' : None,
    'proxyType' : "MANUAL",
    'class' : "org.openqa.selenium.Proxy",
    'autodetect' : False
}

driver = webdriver.Chrome( executable_path="path_to_chrome", desired_capabilities=capabilities, skip_capabilities_update=True )

Generally, you can design a class that behaves like a dictionary, mainly be implementing the methods __contains__, __getitem__, __delitem__, __setitem__ and some more. That class can have any behaviour you like, for example prividing a sorted iterator over the keys ...

I think the easiest would be something like:

// Joda Time

DateTime dateTime=new DateTime(); 

StartOfDayMillis = dateTime.withMillis(System.currentTimeMillis()).withTimeAtStartOfDay().getMillis();
EndOfDayMillis = dateTime.withMillis(StartOfDayMillis).plusDays(1).minusSeconds(1).getMillis();

These millis can be then converted into Calendar,Instant or LocalDate as per your requirement with Joda Time.

In my case, I wanted to enable/disable the cursor when the edit is focused.

In your Activity:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    if (ev.getAction() == MotionEvent.ACTION_DOWN) {
        View v = getCurrentFocus();
        if (v instanceof EditText) {
            EditText edit = ((EditText) v);
            Rect outR = new Rect();
            edit.getGlobalVisibleRect(outR);
            Boolean isKeyboardOpen = !outR.contains((int)ev.getRawX(), (int)ev.getRawY());
            System.out.print("Is Keyboard? " + isKeyboardOpen);
            if (isKeyboardOpen) {
                System.out.print("Entro al IF");
                edit.clearFocus();
                InputMethodManager imm = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(edit.getWindowToken(), 0);
            }

            edit.setCursorVisible(!isKeyboardOpen);

        }
    }
    return super.dispatchTouchEvent(ev);
}

Declaring a method as static means we can call that method by its class name and if that class is abstract as well, it makes no sense to call it as it does not contain any body, and hence we cannot declare a method both as static and abstract.

The != operator most certainly does exist! It is an alias for the standard <> operator.

Perhaps your fields are not actually empty strings, but instead NULL?

To compare to NULL you can use IS NULL or IS NOT NULL or the null safe equals operator <=>.

You can use functions in pyspark.sql.functions: functions like year, month, etc

refer to here: https://spark.apache.org/docs/latest/api/python/pyspark.sql.html#pyspark.sql.DataFrame

from pyspark.sql.functions import *

newdf = elevDF.select(year(elevDF.date).alias('dt_year'), month(elevDF.date).alias('dt_month'), dayofmonth(elevDF.date).alias('dt_day'), dayofyear(elevDF.date).alias('dt_dayofy'), hour(elevDF.date).alias('dt_hour'), minute(elevDF.date).alias('dt_min'), weekofyear(elevDF.date).alias('dt_week_no'), unix_timestamp(elevDF.date).alias('dt_int'))

newdf.show()

def function(arg)->123:

It's simply a return type, integer in this case doesn't matter which number you write.

like Java :

public int function(int args){...}

But for Python (how Jim Fasarakis Hilliard said) the return type it's just an hint, so it's suggest the return but allow anyway to return other type like a string..

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

I could happen that if your array contains the string "hello", and if you are searching for "he", grep returns true, although, "he" may not be an array element.

Perhaps,

if (grep(/^$match$/, @array)) more apt.

Similar approach to @Samuel-bergström:

• Download Fontawesome SVG https://github.com/FortAwesome/Font-Awesome/blob/master/src/assets/font-awesome/fonts/fontawesome-webfont.svg
• Download FontForge http://fontforge.github.io/en-US/downloads/
• Download Inkscape
• Open Inskscape and create a single layer shape as your new font icon
• Save SVG file, Close Inkscape
• Open FontForge (If you have multiple monitors, use Windows-LeftArrow, to reposition as they have strange SWING java windows that go off monitor, and have modal problems with popups - I had to check my task bar for some)
• File | Open fontawesome-webfont.svg
• File | Import
• Scroll to the bottom, Right Click on Icon | Glyph Info
• Update Glyph Name to uniFXXX (XXX is something like 501, a higher number than the highest Unicode used in v4.5 of FontAwesome)
• Unicode Vlaue U+fXXX
• Click OK
• File | Save
• File | Generate Fonts ...
• Close FontForge
• Open your web project
• Copy your font files to the (in my project) "\Content\fonts\" folder.
• Edit "\Content\styles\fa\path.less" to be like:

@font-face {_x000D_
      font-family: 'FontAwesome';_x000D_
      //src: url('@{fa-font-path}/fontawesome-webfont.eot?v=@{fa-version}');_x000D_
      src: _x000D_
     //url('@{fa-font-path}/fontawesome-webfont.eot?#iefix&v=@{fa-version}') format('embedded-opentype'),_x000D_
        //url('@{fa-font-path}/fontawesome-webfont.woff2?v=@{fa-version}') format('woff2'),_x000D_
        url('@{fa-font-path}/fontawesomeregular.woff?v=@{fa-version}') format('woff'),_x000D_
        url('@{fa-font-path}/fontawesomeregular.ttf?v=@{fa-version}') format('truetype'),_x000D_
        url('@{fa-font-path}/fontawesomeregular.svg?v=@{fa-version}#fontawesomeregular') format('svg');_x000D_
    //  src: url('@{fa-font-path}/FontAwesome.otf') format('opentype'); // used when developing fonts_x000D_
      font-weight: normal;_x000D_
      font-style: normal;_x000D_
    }

I know it may be 'controversial' to comment out other file types, but happy to hear how to generate .eot or .otf files in the comments.

• and finally, as Samuel mentions, update your CSS/LESS with:

  .fa-XXX:before { content: "\f501"; }

If your application has minimum sdk version 16 then you can use finishAffinity()

Finish this activity as well as all activities immediately below it in the current task that have the same affinity.

This is work for me In Top Payment screen remove all back-stack activits,

@Override
public void onBackPressed() {
         finishAffinity();
        startActivity(new Intent(PaymentDoneActivity.this,Home.class));
    } 

http://developer.android.com/reference/android/app/Activity.html#finishAffinity%28%29

You can stash away your changes, then drop the stash:

git stash
git stash drop

For me it was changing.

this.name = response.data;

To what computed returns so;

this.$store.state.name = response.data;

You can use the standard Python idiom, vars():

for attr, value in vars(k).items():
    print(attr, '=', value)

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

If you need to access those certs programmatically it is best to not use the file at all, but access it via the trust manager. The following code is from a OpenJDK Test case (which makes sure the built cacerts collection is not empty):

TrustManagerFactory trustManagerFactory =
    TrustManagerFactory.getInstance("PKIX");
trustManagerFactory.init((KeyStore) null);
TrustManager[] trustManagers =
    trustManagerFactory.getTrustManagers();
X509TrustManager trustManager =
    (X509TrustManager) trustManagers[0];
X509Certificate[] acceptedIssuers =
    trustManager.getAcceptedIssuers();

So you don’t have to deal with file location or keystore password.

Try this code

final EditText editText = findViewById(R.id.name); // your edittext id in xml
Button submit = findViewById(R.id.submit_button); // your button id in xml
submit.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) 
    {
        String string = editText.getText().toString();
        Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
    }
});

The old-school (pre-PEP 3119) way to do this is just to raise NotImplementedError in the abstract class when an abstract method is called.

class Abstract(object):
    def foo(self):
        raise NotImplementedError('subclasses must override foo()!')

class Derived(Abstract):
    def foo(self):
        print 'Hooray!'

>>> d = Derived()
>>> d.foo()
Hooray!
>>> a = Abstract()
>>> a.foo()
Traceback (most recent call last): [...]

This doesn't have the same nice properties as using the abc module does. You can still instantiate the abstract base class itself, and you won't find your mistake until you call the abstract method at runtime.

But if you're dealing with a small set of simple classes, maybe with just a few abstract methods, this approach is a little easier than trying to wade through the abc documentation.

=IF(COUNTIF(A1:D1,FALSE)>0,FALSE,TRUE)

(or you can specify any other range to look in)

With SQLServer 2005 Express, what I found was that even with autocommit off, insertions into a Db table were committed without my actually issuing a commit command from the Management Studio session. The only difference was, when autocommit was off, I could roll back all the insertions; with *autocommit on, I could not.* Actually, I was wrong. With autocommit mode off, I see the changes only in the QA (Query Analyzer) window from which the commands were issued. If I popped a new QA (Query Analyzer) window, I do not see the changes made by the first window (session), i.e. they are NOT committed! I had to issue explicit commit or rollback commands to make changes visible to other sessions(QA windows) -- my bad! Things are working correctly.

You can use IF EXIST to check for a file:

IF EXIST "filename" (
  REM Do one thing
) ELSE (
  REM Do another thing
)

If you do not need an "else", you can do something like this:

set __myVariable=
IF EXIST "C:\folder with space\myfile.txt" set __myVariable=C:\folder with space\myfile.txt
IF EXIST "C:\some other folder with space\myfile.txt" set __myVariable=C:\some other folder with space\myfile.txt
set __myVariable=

Here's a working example of searching for a file or a folder:

REM setup

echo "some text" > filename
mkdir "foldername"

REM finds file    

IF EXIST "filename" (
  ECHO file filename exists
) ELSE (
  ECHO file filename does not exist
)

REM does not find file

IF EXIST "filename2.txt" (
  ECHO file filename2.txt exists
) ELSE (
  ECHO file filename2.txt does not exist
)

REM folders must have a trailing backslash    

REM finds folder

IF EXIST "foldername\" (
  ECHO folder foldername exists
) ELSE (
  ECHO folder foldername does not exist
)

REM does not find folder

IF EXIST "filename\" (
  ECHO folder filename exists
) ELSE (
  ECHO folder filename does not exist
)

You can simply write:

char c = (char) 2;

or

char c = Convert.ToChar(2);

or more complex option for ASCII encoding only

char[] characters = System.Text.Encoding.ASCII.GetChars(new byte[]{2});
char c = characters[0];

You can use isTRUE for such cases. isTRUE is the same as { is.logical(x) && length(x) == 1 && !is.na(x) && x }

If you use shiny there you could use isTruthy which covers the following cases:

• FALSE

• NULL

• ""

• An empty atomic vector

• An atomic vector that contains only missing values

• A logical vector that contains all FALSE or missing values

• An object of class "try-error"

• A value that represents an unclicked actionButton()

Try Cactoos:

new LengthOf(new TeeInput(input, output)).value();

More details here: http://www.yegor256.com/2017/06/22/object-oriented-input-output-in-cactoos.html

In addition to Jesse Glick answer, if you want to pass string parameter then use:

build job: 'your-job-name', 
    parameters: [
        string(name: 'passed_build_number_param', value: String.valueOf(BUILD_NUMBER)),
        string(name: 'complex_param', value: 'prefix-' + String.valueOf(BUILD_NUMBER))
    ]

infinite slider adapter skeleton based on previous samples

some critical issues:

• remember original (relative) position in page view (tag used in sample), so we will look this position to define relative position of view. otherwise child order in pager is mixed
• have to fill first time absolute view inside adapter. (the rest of times this fill will be invalid) found no way to force it fill from pager handler. the rest times absolute view will be overriden from pager handler with correct values.
• when pages are slided quickly, side page (actually left) is not filled from pager handler. no workaround for the moment, just use empty view, it will be filled with actual values when drag is stopped. upd: quick workaround: disable adapter's destroyItem.

you may look at the logcat to understand whats happening in this sample

If you are requesting only page data, then you can use a page access token. You will only have to authorize the user once to get the user access token; extend it to two months validity then request the token for the page. This is all explained in Scenario 5. Note, that the acquired page access token is only valid for as long as the user access token is valid.

This is just to mention entr as an alternative on OSX to run arbitrary commands when files change. I find it simple and useful.

Are you re-running your checkout or export into an existing directory?

Because if you are, checkout will update the working copy, including deleting any files.

But export will simply transfer all the files from the reporsitory to the destination - if the destination is the same directory, this means any files deleted in the repository will NOT be deleted.

So you export copy may only work because it is relying on a file which has been deleted in the repository?

I solved this issue just by adding

import { AppRegistry } from "react-native";
import App from "./App";
import { name as appName } from "./app.json";  
AppRegistry.registerComponent(appName, () => App);

to my index.js

make sure this exists in your index.js

You should trigger the animation to revert once it's completed w/ javascript.

  $(".item").live("animationend webkitAnimationEnd", function(){
    $(this).removeClass('animate');
  });

Webpack is a bundler. Like Browserfy it looks in the codebase for module requests (require or import) and resolves them recursively. What is more, you can configure Webpack to resolve not just JavaScript-like modules, but CSS, images, HTML, literally everything. What especially makes me excited about Webpack, you can combine both compiled and dynamically loaded modules in the same app. Thus one get a real performance boost, especially over HTTP/1.x. How exactly you you do it I described with examples here http://dsheiko.com/weblog/state-of-javascript-modules-2017/ As an alternative for bundler one can think of Rollup.js (https://rollupjs.org/), which optimizes the code during compilation, but stripping all the found unused chunks.

For AMD, instead of RequireJS one can go with native ES2016 module system, but loaded with System.js (https://github.com/systemjs/systemjs)

Besides, I would point that npm is often used as an automating tool like grunt or gulp. Check out https://docs.npmjs.com/misc/scripts. I personally go now with npm scripts only avoiding other automation tools, though in past I was very much into grunt. With other tools you have to rely on countless plugins for packages, that often are not good written and not being actively maintained. npm knows its packages, so you call to any of locally installed packages by name like:

{
  "scripts": {
    "start": "npm http-server"
  },
  "devDependencies": {
    "http-server": "^0.10.0"
  }
}

Actually you as a rule do not need any plugin if the package supports CLI.

Either != or ne will work, but you need to get the accessor syntax and nested quotes sorted out.

<c:if test="${content.contentType.name ne 'MCE'}">
    <%-- snip --%>
</c:if>

I'm not sure it's a standard construct, but I think you should have a look on "negative lookahead" (which writes : "?!", without the quotes). It's far easier than all answers in this thread, including the accepted one.

Example : Regex : "^(?!123)[0-9]*\w" Captures any string beginning by digits followed by letters, UNLESS if "these digits" are 123.

http://msdn.microsoft.com/en-us/library/az24scfc%28v=vs.110%29.aspx#grouping_constructs (microsoft page, but quite comprehensive) for lookahead / lookbehind

PS : it works well for me (.Net). But if I'm wrong on something, please let us know. I find this construct very simple and effective, so I'm surprised of the accepted answer.

As another anwsers told, you can change in a Session Listener. But you can change it directly in your servlet, for example.

getRequest().getSession().setMaxInactiveInterval(123);

A regular expression can be used to match the time substring in the string returned from the toString() method of the Date object, which is formatted as follows: "Thu Jul 05 2012 02:45:12 GMT+0100 (GMT Daylight Time)". Note that this solution uses the time since the epoch: midnight of January 1, 1970. This solution can be a one-liner, though splitting it up makes it much easier to understand.

function secondsToTime(seconds) {
    const start = new Date(1970, 1, 1, 0, 0, 0, 0).getTime();
    const end = new Date(1970, 1, 1, 0, 0, parseInt(seconds), 0).getTime();
    const duration = end - start;

    return new Date(duration).toString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1");
}

Try this

{% if var in ['foo', 'bar', 'beer'] %}
    ...
{% endif %}

You can get Current timestamp in Android by trying below code

time.setText(String.valueOf(System.currentTimeMillis()));

and timeStamp to time format

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateString = formatter.format(new Date(Long.parseLong(time.getText().toString())));
time.setText(dateString);

Since the driver.window_handles is not in order , a better solution is this.

first switch to the first tab using the shortcut Control + X to switch to the 'x' th tab in the browser window .

driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL + "1");
# goes to 1st tab

driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL + "4");
# goes to 4th tab if its exists or goes to last tab.

I'm going to show you 2 ways. If you don't need a lot of stats in your project simply implement following.

public double average(ArrayList<Double> x) {
    double sum = 0;
    for (double aX : x) sum += aX;
    return (sum / x.size());
}

If you plan on doing a lot of stats might as well not reinvent the wheel. So why not check out http://commons.apache.org/proper/commons-math/userguide/stat.html

You'll fall into true luv!

You can stash and stash pop the file:

git checkout branch1
git checkout branch2 file.py
git stash
git checkout branch1
git stash pop

CURL-less method with PHP5:

$url = 'http://server.com/path';
$data = array('key1' => 'value1', 'key2' => 'value2');

// use key 'http' even if you send the request to https://...
$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data)
    )
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }

var_dump($result);

See the PHP manual for more information on the method and how to add headers, for example:

• stream_context_create: http://php.net/manual/en/function.stream-context-create.php

If you have this error in RStudio, use Lauren's environmental code above and change your R version to the 32 bit version in Tools, Global Options. There should be both 32bit and 64bit R options if you have a newer version. This will require a restart of R, and limit your memory options. Installing the 64 bit version of the jre won't be required though.

With numpy :

im = Image.open('image.gif')
im_matrix = np.array(im)
print(im_matrix[0][0])

Give RGB vector of the pixel in position (0,0)

I couldn't possibly explain it better than wikipedia does: http://en.wikipedia.org/wiki/MIME_type

In addition to e-mail applications, Web browsers also support various MIME types. This enables the browser to display or output files that are not in HTML format.

IOW, it helps the browser (or content consumer, because it may not just be a browser) determine what content they are about to consume; this means a browser may be able to make a decision on the correct plugin to use to display content, or a media player may be able to load up the correct codec or plugin.

The best approach to add padding to a UILabel is to subclass UILabel and add an edgeInsets property. You then set the desired insets and the label will be drawn accordingly.

OSLabel.h

#import <UIKit/UIKit.h>

@interface OSLabel : UILabel

@property (nonatomic, assign) UIEdgeInsets edgeInsets;

@end

OSLabel.m

#import "OSLabel.h"

@implementation OSLabel

- (id)initWithFrame:(CGRect)frame{
    self = [super initWithFrame:frame];
    if (self) {
        self.edgeInsets = UIEdgeInsetsMake(0, 0, 0, 0);
    }
    return self;
}

- (void)drawTextInRect:(CGRect)rect {
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, self.edgeInsets)];
}

- (CGSize)intrinsicContentSize
{
    CGSize size = [super intrinsicContentSize];
    size.width  += self.edgeInsets.left + self.edgeInsets.right;
    size.height += self.edgeInsets.top + self.edgeInsets.bottom;
    return size;
}

@end

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

You must use the column names and then set the values to insert (both ? marks):

//insert 1st row            
String inserting = "INSERT INTO employee(emp_name ,emp_address) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1, "hans");
ps.setString(2, "germany");
ps.executeUpdate();

On debian where bsd-mailx is installed by default, the -r option does not work. However you can use mailx -s subject [email protected] -- -f [email protected] instead. According to man page, you can specify sendmail options after --.

SELECT SUBSTRING('[email protected]',1,(CHARINDEX('@','[email protected]')-1)) Before, RIGHT('[email protected]',(CHARINDEX('@','[email protected]')+1)) After

The solution which worked for me was to upgrade my setuptools:

python3 -m pip install --upgrade pip setuptools wheel

My own implementation of generic restTemplate call:

private <REQ, RES> RES queryRemoteService(String url, HttpMethod method, REQ req, Class reqClass) {
    RES result = null;
    try {
        long startMillis = System.currentTimeMillis();

        // Set the Content-Type header
        HttpHeaders requestHeaders = new HttpHeaders();
        requestHeaders.setContentType(new MediaType("application","json"));            

        // Set the request entity
        HttpEntity<REQ> requestEntity = new HttpEntity<>(req, requestHeaders);

        // Create a new RestTemplate instance
        RestTemplate restTemplate = new RestTemplate();

        // Add the Jackson and String message converters
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
        restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

        // Make the HTTP POST request, marshaling the request to JSON, and the response to a String
        ResponseEntity<RES> responseEntity = restTemplate.exchange(url, method, requestEntity, reqClass);
        result = responseEntity.getBody();
        long stopMillis = System.currentTimeMillis() - startMillis;

        Log.d(TAG, method + ":" + url + " took " + stopMillis + " ms");
    } catch (Exception e) {
         Log.e(TAG, e.getMessage());
    }
    return result;
}

To add some context, I'm consuming RESTful service with this, hence all requests and responses are wrapped into small POJO like this:

public class ValidateRequest {
  User user;
  User checkedUser;
  Vehicle vehicle;
}

and

public class UserResponse {
  User user;
  RequestResult requestResult;
}

Method which calls this is the following:

public User checkUser(User user, String checkedUserName) {
    String url = urlBuilder()
            .add(USER)
            .add(USER_CHECK)
            .build();

    ValidateRequest request = new ValidateRequest();
    request.setUser(user);
    request.setCheckedUser(new User(checkedUserName));

    UserResponse response = queryRemoteService(url, HttpMethod.POST, request, UserResponse.class);
    return response.getUser();
}

And yes, there's a List dto-s as well.

The severity level 16 in your example code is typically used for user-defined (user-detected) errors. The SQL Server DBMS itself emits severity levels (and error messages) for problems it detects, both more severe (higher numbers) and less so (lower numbers).

The state should be an integer between 0 and 255 (negative values will give an error), but the choice is basically the programmer's. It is useful to put different state values if the same error message for user-defined error will be raised in different locations, e.g. if the debugging/troubleshooting of problems will be assisted by having an extra indication of where the error occurred.

you could use powershell script like this

$sb = new-object System.Text.StringBuilder

foreach ($file in Get-ChildItem -path 'C:\temp\xx\') {
    $content = Get-Content -Path $file.fullname
    $sb.Append($content)
}
Out-File -FilePath 'C:\temp\xx\c.txt' -InputObject $sb.toString()

A simple solution to this problem is to return from the render loop if the frame is not required to render:

const FPS = 60;
let prevTick = 0;    

function render() 
{
    requestAnimationFrame(render);

    // clamp to fixed framerate
    let now = Math.round(FPS * Date.now() / 1000);
    if (now == prevTick) return;
    prevTick = now;

    // otherwise, do your stuff ...
}

It's important to know that requestAnimationFrame depends on the users monitor refresh rate (vsync). So, relying on requestAnimationFrame for game speed for example will make it unplayable on 200Hz monitors if you're not using a separate timer mechanism in your simulation.

Like Robert Nishihara mentioned, Apache Arrow makes this easy, specifically with the Plasma in-memory object store, which is what Ray is built on.

I made brain-plasma specifically for this reason - fast loading and reloading of big objects in a Flask app. It's a shared-memory object namespace for Apache Arrow-serializable objects, including pickle'd bytestrings generated by pickle.dumps(...).

The key difference with Apache Ray and Plasma is that it keeps track of object IDs for you. Any processes or threads or programs that are running on locally can share the variables' values by calling the name from any Brain object.

$ pip install brain-plasma

$ plasma_store -m 10000000 -s /tmp/plasma

from brain_plasma import Brain
brain = Brain(path='/tmp/plasma/)

brain['a'] = [1]*10000

brain['a']
# >>> [1,1,1,1,...]

this solution uses the jquery library

$('#elementId').append("<div class='classname'>content</div>");

You can access the Image File and data from a form using MULTIPART FORM DATA By using the below code.

@POST
@Path("/UpdateProfile")
@Consumes(value={MediaType.APPLICATION_JSON,MediaType.MULTIPART_FORM_DATA})
@Produces(value={MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
public Response updateProfile(
    @FormDataParam("file") InputStream fileInputStream,
    @FormDataParam("file") FormDataContentDisposition contentDispositionHeader,
    @FormDataParam("ProfileInfo") String ProfileInfo,
    @FormDataParam("registrationId") String registrationId) {

    String filePath= "/filepath/"+contentDispositionHeader.getFileName();

    OutputStream outputStream = null;
    try {
        int read = 0;
        byte[] bytes = new byte[1024];
        outputStream = new FileOutputStream(new File(filePath));

        while ((read = fileInputStream.read(bytes)) != -1) {
            outputStream.write(bytes, 0, read);
        }

        outputStream.flush();
        outputStream.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (outputStream != null) { 
            try {
                outputStream.close();
            } catch(Exception ex) {}
        }
    }
}

v-model
it is two way data binding, it is used to bind html input element when you change input value then bounded data will be change.

v-model is used only for HTML input elements

ex: <input type="text" v-model="name" > 

v-bind
it is one way data binding,means you can only bind data to input element but can't change bounded data changing input element. v-bind is used to bind html attribute
ex:
<input type="text" v-bind:class="abc" v-bind:value="">

<a v-bind:href="home/abc" > click me </a>

The columns parameter accepts a collection of column names. You're passing a list containing a dataframe with two rows:

>>> [df[1:]]
[  viz  a1_count  a1_mean  a1_std
1   n         0      NaN     NaN
2   n         2       51      50]
>>> df.as_matrix(columns=[df[1:]])
array([[ nan,  nan],
       [ nan,  nan],
       [ nan,  nan]])

Instead, pass the column names you want:

>>> df.columns[1:]

From Ruby 2.3.0 onward, you can combine the safe navigation operator (&.) with Numeric#nonzero?. &. returns nil if the instance was nil and nonzero? - if the number was 0:

if discount&.nonzero?
  # ...
end

Or postfix:

do_something if discount&.nonzero?

We should have the projects which include (at least) all the filtered tags, or said in a different way, exclude the ones which doesn't include all those filtered tags. So we can use Linq Except to get those tags which are not included. Then we can use Count() == 0 to have only those which excluded no tags:

var res = projects.Where(p => filteredTags.Except(p.Tags).Count() == 0);

Or we can make it slightly faster with by replacing Count() == 0 with !Any():

var res = projects.Where(p => !filteredTags.Except(p.Tags).Any());

For AFNetworking 4

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = @{@"user[height]": height,
                         @"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params headers:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

After careful consideration this dillema has a few different solutions:

Aggregate Everything Use an aggregate on each column to get the biggest or smallest field value. This is what I am doing since it takes 2 partially filled out records and "merges" the data.

http://sqlfiddle.com/#!3/59cde/1

SELECT
  UPPER(IDNo) AS user_id
, MAX(FirstName) AS name_first
, MAX(LastName) AS name_last
, MAX(entry) AS row_num
FROM people P
GROUP BY 
  IDNo

Get First (or Last record)

http://sqlfiddle.com/#!3/59cde/23

-- ------------------------------------------------------
-- Notes
-- entry: Auto-Number primary key some sort of unique PK is required for this method
-- IDNo:  Should be primary key in feed, but is not, we are making an upper case version
-- This gets the first entry to get last entry, change MIN() to MAX()
-- ------------------------------------------------------

SELECT 
   PC.user_id
  ,PData.FirstName
  ,PData.LastName
  ,PData.entry
FROM (
  SELECT 
      P2.user_id
     ,MIN(P2.entry) AS rownum
  FROM (
    SELECT
        UPPER(P.IDNo) AS user_id 
      , P.entry 
    FROM people P
  ) AS P2
  GROUP BY 
    P2.user_id
) AS PC
LEFT JOIN people PData
ON PData.entry = PC.rownum
ORDER BY 
   PData.entry

I would recommend a little research on Money Pattern. Martin Fowler in his book Analysis pattern has covered this in more detail.

public class Money {

    private static final Currency USD = Currency.getInstance("USD");
    private static final RoundingMode DEFAULT_ROUNDING = RoundingMode.HALF_EVEN;

    private final BigDecimal amount;
    private final Currency currency;   

    public static Money dollars(BigDecimal amount) {
        return new Money(amount, USD);
    }

    Money(BigDecimal amount, Currency currency) {
        this(amount, currency, DEFAULT_ROUNDING);
    }

    Money(BigDecimal amount, Currency currency, RoundingMode rounding) {
        this.currency = currency;      
        this.amount = amount.setScale(currency.getDefaultFractionDigits(), rounding);
    }

    public BigDecimal getAmount() {
        return amount;
    }

    public Currency getCurrency() {
        return currency;
    }

    @Override
    public String toString() {
        return getCurrency().getSymbol() + " " + getAmount();
    }

    public String toString(Locale locale) {
        return getCurrency().getSymbol(locale) + " " + getAmount();
    }   
}

Coming to the usage:

You would represent all monies using Money object as opposed to BigDecimal. Representing money as big decimal will mean that you will have the to format the money every where you display it. Just imagine if the display standard changes. You will have to make the edits all over the place. Instead using the Money pattern you centralize the formatting of money to a single location.

Money price = Money.dollars(38.28);
System.out.println(price);

You can do get id value by using

test_alert = $('#myDiv').val();_x000D_
alert(test_alert);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="myDiv"><p>Some Text</p></div>

Another solution is to use an SVG text node which is supported by most browsers.

<svg width="50" height="300">
    <text x="28" y="150" transform="rotate(-90, 28, 150)" style="text-anchor:middle; font-size:14px">This text is vertical</text>
</svg>

Use this code if SavedFamilyCode is in the Report Filter:

 Sub FilterPivotTable()
   Application.ScreenUpdating = False
   ActiveSheet.PivotTables("PivotTable2").ManualUpdate = True

   ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode").ClearAllFilters

   ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode").CurrentPage = _
      "K123223"

  ActiveSheet.PivotTables("PivotTable2").ManualUpdate = False
  Application.ScreenUpdating = True
  End Sub

But if the SavedFamilyCode is in the Column or Row Labels use this code:

 Sub FilterPivotTable()
     Application.ScreenUpdating = False
     ActiveSheet.PivotTables("PivotTable2").ManualUpdate = True

      ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode").ClearAllFilters

      ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode").PivotFilters. _
    Add Type:=xlCaptionEquals, Value1:="K123223"

  ActiveSheet.PivotTables("PivotTable2").ManualUpdate = False
  Application.ScreenUpdating = True
  End Sub

Hope this helps you.

Using the auto operator really makes it easy to use as one does not have to worry about the data type and the size of the vector or any other data structure

Iterating vector using auto and for loop

vector<int> vec = {1,2,3,4,5}

for(auto itr : vec)
    cout << itr << " ";

Output:

1 2 3 4 5

You can also use this method to iterate sets and list. Using auto automatically detects the data type used in the template and lets you use it. So, even if we had a vector of string or char the same syntax will work just fine

Can use app:hintTextColor if you use com.google.android.material.textfield.TextInputLayout, try this

 <com.google.android.material.textfield.TextInputLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:hint="@string/app_name" 
     app:hintTextColor="@android:color/white">                   

     <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

In my experience the pythonw.exe is faster at least with using pygame.

With ES6, we now have a simple way to create an Array from a NodeList: the Array.from() function.

// nl is a NodeList
let myArray = Array.from(nl)

Table variables are automatically local and automatically dropped -- you don't have to worry about it.

I noticed that the answers here are using: device-width, device-height, min-device-width, min-device-height, max-device-width, max-device-height.

Please refrain from using them since they are deprecated. see MDN for reference. Instead use the regular min-width, max-width and so on. For extra assurance, you can set the min and max to the same px amount. For example:

iPhone X

@media only screen 
    and (width : 375px) 
    and (height : 635px)
    and (orientation : portrait)  
    and (-webkit-device-pixel-ratio : 3) { }

You may also notice that I am using 635px for height. Try it yourself the window height is actually 635px. run iOS simulator for iPhone X and in Safari Web inspector do window.innerHeight. Here are a few useful links on this subject:

• https://medium.com/@hacknicity/how-ios-apps-adapt-to-the-iphone-x-screen-size-a00bd109bbb9
• https://developer.apple.com/design/human-interface-guidelines/ios/visual-design/adaptivity-and-layout/

Construct and fill out a hidden method=POST action="http://example.com/vote" form and submit it, rather than using window.location at all.

Use print("use this bracket -sample text")

In Python 3 print "Hello world" gives invalid syntax error.

To display string content in Python3 have to use this ("Hello world") brackets.

Do not launch the VS code from the start menu separately. Use

$Code .

command to launch VS code. Now, create your file with the extension .js and Start debugging (F5) it. It will be executed.

Otherwise, restart your system and follow the same process.

The answer that worked with me is what @Anthony had written, but you have to add another line which is

    request.SetupGet(req => req.Headers).Returns(new NameValueCollection());

so you can use this:

HttpContextFactory.Current.Request.Headers.Add(key, value);

This would work for BMP and SIP/SMP characters.

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

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

If you want to add a sourceSet for testing in addition to all the existing ones, within a module regardless of the active flavor:

sourceSets {
    test {
        java.srcDirs += [
                'src/customDir/test/kotlin'
        ]
        print(java.srcDirs)   // Clean
    }
}

Pay attention to the operator += and if you want to run integration tests change test to androidTest.

Recently had this problem but with unkown number of promises.Solved using jQuery.map().

function methodThatChainsPromises(args) {

    //var args = [
    //    'myArg1',
    //    'myArg2',
    //    'myArg3',
    //];

    var deferred = $q.defer();
    var chain = args.map(methodThatTakeArgAndReturnsPromise);

    $q.all(chain)
    .then(function () {
        $log.debug('All promises have been resolved.');
        deferred.resolve();
    })
    .catch(function () {
        $log.debug('One or more promises failed.');
        deferred.reject();
    });

    return deferred.promise;
}

This will do it for you:

var yourSelect = document.getElementById( "your-select-id" );
alert( yourSelect.options[ yourSelect.selectedIndex ].value )

You are trying to call do_something before you declare it. You need to add a function prototype before your printf line:

char* do_something(char*, const char*);

Or you need to move the function definition above the printf line. You can't use a function before it is declared.

It is now possible to specify local Node module installation paths in your package.json directly. From the docs:

Local Paths

As of version 2.0.0 you can provide a path to a local directory that contains a package. Local paths can be saved using npm install -S or npm install --save, using any of these forms:

../foo/bar
~/foo/bar
./foo/bar
/foo/bar

in which case they will be normalized to a relative path and added to your package.json. For example:

{
  "name": "baz",
  "dependencies": {
    "bar": "file:../foo/bar"
  }
}

This feature is helpful for local offline development and creating tests that require npm installing where you don't want to hit an external server, but should not be used when publishing packages to the public registry.

Common confusing issue here is that we have 2 different css properties: word-wrap and word-break. Then on top of that, word-wrap has an option called break-word.. Easy to mix-up :-)

Usually this worked for me, even inside a table: word-break: break-word;

Here's my solution for Bootstrap 4:

<button id="search" class="btn btn-primary" 
data-loading-text="<i class='fa fa-spinner fa-spin fa-fw' aria-hidden='true'></i>Searching">
  Search
</button>

var setLoading = function () {
  var search = $('#search');
  if (!search.data('normal-text')) {
    search.data('normal-text', search.html());
  }
  search.html(search.data('loading-text'));
};

var clearLoading = function () {
  var search = $('#search');
  search.html(search.data('normal-text'));
};

setInterval(() => {
  setLoading();
  setTimeout(() => {
    clearLoading();
  }, 1000);
}, 2000);

I fixed it in my bootstrap page by setting the min-width and max-width to the same value in the select and then setting the select:focus to auto.

select {_x000D_
  min-width: 120px;_x000D_
  max-width: 120px;_x000D_
}_x000D_
select:focus {_x000D_
  width: auto;_x000D_
}

<select style="width: 120px">_x000D_
  <option>REALLY LONG TEXT, REALLY LONG TEXT, REALLY LONG TEXT</option>_x000D_
  <option>ABC</option>_x000D_
</select>

content: "";
background-image: url("yourimage.jpg");
background-size: 30px, 30px;

Much has changed for MySQL 8. I've found the following modification of the MySQL 8.0 "How to Reset the Root Password" documentation works with Mac OS X.

Create a temp file $HOME/mysql.root.txt with the SQL to update the root password:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '<new-password>';

This uses mysql_native_password to avoid the Authentication plugin 'caching_sha2_password' cannot be loaded error, which I get if I omit the option.

Stop the server, start with an --init-file option to set the root password, then restart the server:

mysql.server stop mysql.server start --init-file=$HOME/mysql.root.txt mysql.server stop mysql.server start

I usually go with PNG, as it seems to have a few advantages over GIF. There used to be patent restrictions on GIF, but those have expired.

GIFs are suitable for sharp-edged line art (such as logos) with a limited number of colors. This takes advantage of the format's lossless compression, which favors flat areas of uniform color with well defined edges (in contrast to JPEG, which favors smooth gradients and softer images).

GIFs can be used for small animations and low-resolution film clips.

In view of the general limitation on the GIF image palette to 256 colors, it is not usually used as a format for digital photography. Digital photographers use image file formats capable of reproducing a greater range of colors, such as TIFF, RAW or the lossy JPEG, which is more suitable for compressing photographs.

The PNG format is a popular alternative to GIF images since it uses better compression techniques and does not have a limit of 256 colors, but PNGs do not support animations. The MNG and APNG formats, both derived from PNG, support animations, but are not widely used.

The answer of @cheez sometime doesn't work and recursively call the function again and again. To solve this problem you should copy the function deeply. You can do this by using the function partial, so the final code is:

import numpy as np
from functools import partial

# save np.load
np_load_old = partial(np.load)

# modify the default parameters of np.load
np.load = lambda *a,**k: np_load_old(*a, allow_pickle=True, **k)

# call load_data with allow_pickle implicitly set to true
(train_data, train_labels), (test_data, test_labels) = 
imdb.load_data(num_words=10000)

# restore np.load for future normal usage
np.load = np_load_old

Here's how you should do it:

change_column :users, :admin, :boolean, :default => false

But some databases, like PostgreSQL, will not update the field for rows previously created, so make sure you update the field manaully on the migration too.

So I can tell there aren't enough opinions or reinvented wheels in this thread, so I decided to spice things up.

Below is a procedure that:

• is focused (only affects) on sequences that are associated with tables
• works for both SERIAL and GENERATED AS IDENTITY columns
• works for good_column_names and "BAD_column_123" names
• automatically assigns the respective sequences' defined start value if the table is empty
• allows for a specific sequences to be affected only (in schema.table.column notation)
• has a preview mode

CREATE OR REPLACE PROCEDURE pg_reset_all_table_sequences(
    IN commit_mode BOOLEAN DEFAULT FALSE
,   IN mask_in TEXT DEFAULT NULL

to commit:

call pg_reset_all_table_sequences(true);

to specify only your target table:

call pg_reset_all_table_sequences('schema.table.column');

It depends on what database you are using. In MySQL, you would use the "ALTER TABLE" syntax. I don't remember exactly how, but it would go something like this if you wanted to add a column called 'newcol' that was a 200 character varchar:

ALTER TABLE example ADD newCol VARCHAR(200) AFTER otherCol;

I think the below rules are recommended for a default wordpress site:

• For folders inside wp-content, set 0755 permissions:

  chmod -R 0755 plugins

  chmod -R 0755 uploads

  chmod -R 0755 upgrade

• Let apache user be the owner for the above directories of wp-content:

  chown apache uploads

  chown apache upgrade

  chown apache plugins

I think my solution is more simple with default functionality.

In my case, I needed a requirement to parse out the page title AND and have all the other goodness of jQuery, minus it firing scripts. Here is my solution that seems to work.

        $.get('/somepage.htm', function (data) {
            // excluded code to extract title for simplicity
            var bodySI = data.indexOf('<body>') + '<body>'.length,
                bodyEI = data.indexOf('</body>'),
                body = data.substr(bodySI, bodyEI - bodySI),
                $body;

            body = body.replace(/<script[^>]*>/gi, ' <!-- ');
            body = body.replace(/<\/script>/gi, ' --> ');

            //console.log(body);

            $body = $('<div>').html(body);
            console.log($body.html());
        });

This kind of shortcuts worries about script because you are not trying to remove out the script tags and content, instead you are replacing them with comments rendering schemes to break them useless as you would have comments delimiting your script declarations.

Let me know if that still presents a problem as it will help me too.

The #define allows you to establish a value in a header that would otherwise compile to size-greater-than-zero. Your headers should not compile to size-greater-than-zero.

// File:  MyFile.h

// This header will compile to size-zero.
#define TAX_RATE 0.625

// NO:  static const double TAX_RATE = 0.625;
// NO:  extern const double TAX_RATE;  // WHAT IS THE VALUE?

EDIT: As Neil points out in the comment to this post, the explicit definition-with-value in the header would work for C++, but not C.

Bower uses semver syntax, but here are a few quick examples:

You can install a specific version:

$ bower install jquery#1.11.1

You can use ~ to specify 'any version that starts with this':

$ bower install jquery#~1.11

You can specify multiple version requirements together:

$ bower install "jquery#<2.0 >1.10"

Here is an alternate way to add a custom separator line to a UITableView by making a CALayer for the image and using that as the separator line.

// make a CALayer for the image for the separator line

CALayer *separator = [CALayer layer];
separator.contents = (id)[UIImage imageNamed:@"myImage.png"].CGImage;
separator.frame = CGRectMake(0, 54, self.view.frame.size.width, 2);
[cell.layer addSublayer:separator];

I think this should be:

$('.home').click(function() {
     $(this).css('background', 'url(images/tabs3.png)');
 });

and remove this:

<div class="home" onclick="function()">
     //-----------^^^^^^^^^^^^^^^^^^^^---------no need for this

You have to make sure you have a correct path to your image.

• Toggle case "HellO" to "hELLo" with g~ then a movement.
• Uppercase "HellO" to "HELLO" with gU then a movement.
• Lowercase "HellO" to "hello" with gu then a movement.

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

Example

pandas >= 1.0

convert_dtypes

The (self) accepted answer doesn't take into consideration the possibility of NaNs in object columns.

df = pd.DataFrame({
     'a': [1, 2, np.nan], 
     'b': [True, False, np.nan]}, dtype=object) 
df                                                                         

     a      b
0    1   True
1    2  False
2  NaN    NaN

df['a'].astype(str).astype(int) # raises ValueError

This chokes because the NaN is converted to a string "nan", and further attempts to coerce to integer will fail. To avoid this issue, we can soft-convert columns to their corresponding nullable type using convert_dtypes:

df.convert_dtypes()                                                        

      a      b
0     1   True
1     2  False
2  <NA>   <NA>

df.convert_dtypes().dtypes                                                 

a      Int64
b    boolean
dtype: object

If your data has junk text mixed in with your ints, you can use pd.to_numeric as an initial step:

s = pd.Series(['1', '2', '...'])
s.convert_dtypes()  # converts to string, which is not what we want

0      1
1      2
2    ...
dtype: string 

# coerces non-numeric junk to NaNs
pd.to_numeric(s, errors='coerce')

0    1.0
1    2.0
2    NaN
dtype: float64

# one final `convert_dtypes` call to convert to nullable int
pd.to_numeric(s, errors='coerce').convert_dtypes() 

0       1
1       2
2    <NA>
dtype: Int64

All fine, but this should also work from env:

PROCESSOR_ARCHITECTURE=x86

..

PROCESSOR_ARCHITECTURE=AMD64

Too easy, maybe ;-)

As others have pointed out, you can have an if statement inside your catch block to determine what is going on. C#6 supports Exception Filters, so the following will work:

try { … }
catch (Exception e) when (MyFilter(e))
{
    …
}

The MyFilter method could then look something like this:

private bool MyFilter(Exception e)
{
  return e is ArgumentNullException || e is FormatException;
}

Alternatively, this can be all done inline (the right hand side of the when statement just has to be a boolean expression).

try { … }
catch (Exception e) when (e is ArgumentNullException || e is FormatException)
{
    …
}

This is different from using an if statement from within the catch block, using exception filters will not unwind the stack.

You can download Visual Studio 2015 to check this out.

If you want to continue using Visual Studio 2013, you can install the following nuget package:

Install-Package Microsoft.Net.Compilers

At time of writing, this will include support for C# 6.

Referencing this package will cause the project to be built using the specific version of the C# and Visual Basic compilers contained in the package, as opposed to any system installed version.

Try

private boolean hasKey(JSONObject jsonObject, String key) {
    return jsonObject != null && jsonObject.has(key);
}

  try {
        JSONObject jsonObject = new JSONObject(yourJson);
        if (hasKey(jsonObject, "labelData")) {
            JSONObject labelDataJson = jsonObject.getJSONObject("LabelData");
            if (hasKey(labelDataJson, "video")) {
                String video = labelDataJson.getString("video");
            }
        }
    } catch (JSONException e) {

    }

If you're working on the heroku remote (default):

heroku git:remote -a [app name]

If you want to specify a different remote, use the -r argument:

heroku git:remote -a [app name] -r [remote] 

EDIT: thanks to ??????? ???????? For pointing it out that there's no need to delete the old remote.

If you need to do this on the backend you can use the following URL structure:

https://maps.googleapis.com/maps/api/geocode/json?address=[STREET_ADDRESS]&key=[YOUR_API_KEY]

Sample PHP code using curl:

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, 'https://maps.googleapis.com/maps/api/geocode/json?address=' . rawurlencode($address) . '&key=' . $api_key);

curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);

$json = curl_exec($curl);

curl_close ($curl);

$obj = json_decode($json);

See additional documentation for more details and expected json response.

The docs provide sample output and will assist you in getting your own API key in order to be able to make requests to the Google Maps Geocoding API.

In C the char type has a numeric value so the > operator will work just fine for example

#include <stdio.h>
main() {

    char a='z';

    char b='h';

    if ( a > b ) {
        printf("%c greater than %c\n",a,b);
    }
}

 private static T[] prepareArray<T>(T[] arrayToCopy, T value)
    {
        Array.Copy(arrayToCopy, 1, arrayToCopy, 0, arrayToCopy.Length - 1);
        arrayToCopy[arrayToCopy.Length - 1] = value;
        return (T[])arrayToCopy;
    }

I was performing this throughout my code and wanted a way to put it into a method. I wanted to share this here because I didn't have to use the Convert.ChangeType for my return value. This may not be a best practice but it worked for me. This method takes in an array of generic type and a value to add to the end of the array. The array is then copied with the first value stripped and the value taken into the method is added to the end of the array. The last thing is that I return the generic array.

Also with dict

a = []
b = {1:'one'}

a.append(dict(b))
print a
b[1]='iuqsdgf'
print a

result

[{1: 'one'}]
[{1: 'one'}]

You simply combine the ideas of a link to another page, as with href=foo.html, and a link to an element on the same page, as with href=#bar, so that the fragment like #bar is written immediately after the URL that refers to another page:

<a href="foo.html#bar">Some nice link text</a>

The target is specified the same was as when linking inside one page, e.g.

<div id="bar">
<h2>Some heading</h2>
Some content
</div>

or (if you really want to link specifically to a heading only)

<h2 id="bar">Some heading</h2>

If you need to put results to a file, you can use

(echo a & echo. & echo b) > file_containing_multiple_lines.txt

matrix multiplication, see the following example:

> A <- matrix (c(1,3,4, 5,8,9, 1,3,3), 3,3)
> A
     [,1] [,2] [,3]
[1,]    1    5    1
[2,]    3    8    3
[3,]    4    9    3
> 
> B <- matrix (c(2,4,5, 8,9,2, 3,4,5), 3,3)
> 
> B
     [,1] [,2] [,3]
[1,]    2    8    3
[2,]    4    9    4
[3,]    5    2    5
>

> A %*% B
     [,1] [,2] [,3]
[1,]   27   55   28
[2,]   53  102   56
[3,]   59  119   63

     [,1] [,2] [,3]
[1,]   38  101   35
[2,]   47  128   43
[3,]   31   86   26

Also see:

http://en.wikipedia.org/wiki/Matrix_multiplication

If this does not follow the size of matrix rule you will get the error:

    Error in A %*% B : non-conformable arguments

If you want your scripts to load after page has been rendered, you can use:

function getScript(a, b) {
    var c = document.createElement("script");
    c.src = a;
    var d = document.getElementsByTagName("head")[0],
        done = false;
    c.onload = c.onreadystatechange = function() {
        if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete")) {
            done = true;
            b();
            c.onload = c.onreadystatechange = null;
            d.removeChild(c)
        }
    };
    d.appendChild(c)
}

//call the function
getScript("http://www.google-analytics.com/ga.js", function() {
    // do stuff after the script has loaded
});

I solved the error by modifying the following property in hibernate.cfg.xml

<property name="hibernate.hbm2ddl.auto">validate</property>

Earlier, the table was getting deleted each time I ran the program and now it doesnt, as hibernate only validates the schema and does not affect changes to it.

As far as I know you can also change from validate to update e.g.:

<property name="hibernate.hbm2ddl.auto">update</property>

A bit surprised to see None of the above answers considers it can be multiple times faster using a thread pool. Here, parallel uses a fork-join thread pool and automatically break the stream in multiple parts and run them parallel and then merge. If you just remember the following line of code you can use it many places.

So the award for the fastest short and sweet code goes to -

int[] nums = {1,2,3};
int sum =  Arrays.stream(nums).parallel().reduce(0, (a,b)-> a+b);

Lets say you want to do sum of squares , then Arrays.stream(nums).parallel().map(x->x*x).reduce(0, (a,b)-> a+b). Idea is you can still perform reduce , without map .

This occurred to me when I applied the 2017 Fall Creator Update. I was able to resolve by repairing IIS 10.0 Express (I do not have IIS installed on my box.)

Note: As a user pointed out in the comments,

Repair can be found in "Programs and Features" - the "classic" control panel.

This should do the trick,

npm install -g typescript

I was struggling with this for some time and after some help on a post I was able to come up with this formula =(DATEVALUE(LEFT(XX,10)))+(TIMEVALUE(MID(XX,12,5))) where XX is the cell in reference.

I've come across many other forums with people asking the same thing and this, to me, seems to be the simplest answer. What this will do is return text that is copied in from this format 2014/11/20 11:53 EST and turn it in to a Date/Time format so it can be sorted oldest to newest. It works with short date/long date and if you want the time just format the cell to display time and it will show. Hope this helps anyone who goes searching around like I did.

Use a 1 line batch file in your install:

SETX PATH "C:\Windows"

run the bat file

Now place your .exe in c:\windows, and you're done.

you may type the 'exename' in command-line and it'll run it.

ALTER TABLE users
  ADD COLUMN "priv_user" BOOLEAN DEFAULT FALSE;

you can also directly specify NOT NULL

ALTER TABLE users
  ADD COLUMN "priv_user" BOOLEAN NOT NULL DEFAULT FALSE;

UPDATE: following is only true for versions before postgresql 11.

As Craig mentioned on filled tables it is more efficient to split it into steps:

ALTER TABLE users ADD COLUMN priv_user BOOLEAN;
UPDATE users SET priv_user = 'f';
ALTER TABLE users ALTER COLUMN priv_user SET NOT NULL;
ALTER TABLE users ALTER COLUMN priv_user SET DEFAULT FALSE;

You can convert a character from lower case to upper case and vice-versa using bit manipulation as shown below:

#include<stdio.h>
int main(){
  char c;
  printf("Enter a character in uppercase\n");
  scanf("%c",&c);
  c|=' '; // perform or operation on c and ' '
  printf("The lower case of %c is \n",c);
  c&='_'; // perform 'and' operation with '_' to get upper case letter. 
  printf("Back to upper case %c\n",c);   
  return 0;
}

This type of data is efficiently pulled from a Trie-like data structure. It also allows for fast sorting. The memory efficiency might not be that great though.

A traditional trie stores each letter of a word as a node in the tree. But in your case your "alphabet" is different. You are storing strings instead of characters.

it might look something like this:

root:                Root
                     /|\
                    / | \
                   /  |  \     
fruit:       Banana Apple Strawberry
              / |      |     \
             /  |      |      \
color:     Blue Yellow Green  Blue
            /   |       |       \
           /    |       |        \
end:      24   100      12        0

see this link: trie in python

it worked for me using this line of code:

<a id="LinkTest" title="Any Title"  href="#" onclick="Function(); return false; ">text</a>

I made a method to do this below called jsonArrayToObjectList. Its a handy static class that will take a filename and the file contains an array in JSON form.

 List<Items> items = jsonArrayToObjectList(
            "domain/ItemsArray.json",  Item.class);

    public static <T> List<T> jsonArrayToObjectList(String jsonFileName, Class<T> tClass) throws IOException {
        ObjectMapper mapper = new ObjectMapper();
        final File file = ResourceUtils.getFile("classpath:" + jsonFileName);
        CollectionType listType = mapper.getTypeFactory()
            .constructCollectionType(ArrayList.class, tClass);
        List<T> ts = mapper.readValue(file, listType);
        return ts;
    }

Just a little addition. If you've only selected 1 row then the code below will select the value of a column (index of 4, but 5th column) for the selected row:

me.lstIssues.Column(4)

This saves having to use the ItemsSelected property.

I just spent some time figure it out. Thoma's answer is not complete. Say your program is test.py, you want to use gpu0 to run this program, and keep other gpus free.

You should write CUDA_VISIBLE_DEVICES=0 python test.py

Notice it's DEVICES not DEVICE

I noticed that Eemuli said that you can't change the log level after they are created - and while that might be the design, it isn't entirely true.

I ran into a situation where I was using a library that logged to slf4j - and I was using the library while writing a maven mojo plugin.

Maven uses a (hacked) version of the slf4j SimpleLogger, and I was unable to get my plugin code to reroute its logging to something like log4j, which I could control.

And I can't change the maven logging config.

So, to quiet down some noisy info messages, I found I could use reflection like this, to futz with the SimpleLogger at runtime.

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.spi.LocationAwareLogger;
    try
    {
        Logger l = LoggerFactory.getLogger("full.classname.of.noisy.logger");  //This is actually a MavenSimpleLogger, but due to various classloader issues, can't work with the directly.
        Field f = l.getClass().getSuperclass().getDeclaredField("currentLogLevel");
        f.setAccessible(true);
        f.set(l, LocationAwareLogger.WARN_INT);
    }
    catch (Exception e)
    {
        getLog().warn("Failed to reset the log level of " + loggerName + ", it will continue being noisy.", e);
    }

Of course, note, this isn't a very stable / reliable solution... as it will break the next time the maven folks change their logger.

I'd set up your HTML like so:

<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" id="bottle" />

Then use the following code:

<script>
var images = document.getElementsByTagName("img");
for(var i = 0; i < images.length; i++) {
    var image = images[i];
    image.onclick = function(event) {
         window.location.href = this.id + '.html';
    };
}
</script>

That assigns an onclick event handler to every image on the page (this may not be what you want, you can limit it further if necessary) that changes the current page to the value of the images id attribute plus the .html extension. It's essentially the pure Javascript implementation of @JanPöschko's jQuery answer.

Subprocess is based on popen2, and as such has a number of advantages - there's a full list in the PEP here, but some are:

• using pipe in the shell
• better newline support
• better handling of exceptions

I did a little research and was able to write this code:

strbody = "<BODY style=font-size:11pt;font-family:Calibri>Good Morning;<p>We have completed our main aliasing process for today.  All assigned firms are complete.  Please feel free to respond with any questions.<p>Thank you.</BODY>"

apparently by setting the "font-size=11pt" instead of setting the font size <font size=5>, It allows you to select a specific font size like you normally would in a text editor, as opposed to selecting a value from 1-7 like my code was originally.

This link from simpLE MAn gave me some good info.

if (jsonObj != null && jsonObj.length > 0)

To check if a nested JSON object is empty within a JSONObject:

if (!jsonObject.isNull("key") && jsonObject.getJSONObject("key").length() > 0)

getcwd();

or

dirname(__FILE__);

or (PHP5)

basename(__DIR__) 

http://php.net/manual/en/function.getcwd.php

http://php.net/manual/en/function.dirname.php

You can use basename() to get the trailing part of the path :)

In your case, I'd say you are most likely looking to use getcwd(), dirname(__FILE__) is more useful when you have a file that needs to include another library and is included in another library.

Eg:

main.php
libs/common.php
libs/images/editor.php

In your common.php you need to use functions in editor.php, so you use

common.php:

require_once dirname(__FILE__) . '/images/editor.php';

main.php:

require_once libs/common.php

That way when common.php is require'd in main.php, the call of require_once in common.php will correctly includes editor.php in images/editor.php instead of trying to look in current directory where main.php is run.

Your pattern is fine. But you shouldn't be split()ting it away, you should find() it. Following code gives the output you are looking for:

String str = "ZZZZL <%= dsn %> AFFF <%= AFG %>";
Pattern pattern = Pattern.compile("<%=(.*?)%>", Pattern.DOTALL);
Matcher matcher = pattern.matcher(str);
while (matcher.find()) {
    System.out.println(matcher.group(1));
}

You can use %

sed -i "s%http://www.fubar.com%URL_FUBAR%g"

Why not use the WordPress core function that's designed specifically for that purpose?

<?php plugin_dir_path( __FILE__ ); ?>

See Codex documentation here.

You also have

<?php plugin_dir_url( __FILE__ ); ?>

if what you're looking for is a URI as opposed to a server path.

See Codex documentation here.

IMO it's always best to use the highest-level method that's available in core, and this is it. It makes your code more future proof.

Well.. Apparently the file does not exist or cannot be found. Try using a full path. You're probably reading from the wrong directory when you don't specify the path, unless a.txt is in your current working directory.

git stash pop

will get everything back in place

as suggested in the comments, you can use git stash branch newbranch to apply the stash to a new branch, which is the same as running:

git checkout -b newbranch
git stash pop

I am writing an application which can run on both x86 and x64 platform for Windows 7 and querying the below variable just pulls the right program files folder path on any platform.

To expand on Solomon Rutzky's answer, if you are looking for a piece of data that shows up in a range (i.e. more than once but less than 5x), you can use

having count(*) > 1 and count(*) < 5

And you can use whatever qualifiers you desire in there - they don't have to match, it's all just included in the 'having' statement. https://webcheatsheet.com/sql/interactive_sql_tutorial/sql_having.php

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

data = pd.read_csv('your_dataset.tsv', delimiter = '\t', quoting = 3)

You can use a delimiter to separate data, quoting = 3 helps to clear quotes in datasst
