Use pngcrush to remove the incorrect sRGB profile from the png file:

pngcrush -ow -rem allb -reduce file.png

• -ow will overwrite the input file
• -rem allb will remove all ancillary chunks except tRNS and gAMA
• -reduce does lossless color-type or bit-depth reduction

In the console output you should see Removed the sRGB chunk, and possibly more messages about chunk removals. You will end up with a smaller, optimized PNG file. As the command will overwrite the original file, make sure to create a backup or use version control.

Having a similar case and I couldn't use StackAttacks solution as he's referring to SDL2 which is for the legacy code I'm using too new.

Fortunately our friends from askUbuntu had something similar:

Download SDL

tar xvf SDL-1.2.tar.gz
cd SDL-1.2
./configure
make
sudo make install

If you have a none-console Windows application, you can create a console with the AllocConsole function. Once created, you can write to it using the normal std::cout methods.

var div = getElementsByTagName('div')[0]; /* first div found; you can use getElementById for more specific element */
div.onclick = null; // OR:
div.onclick = function(){};

//edit

I didn't knew what method are you using for attaching events. For addEventListener you can use this:

div.removeEventListener('click',functionName,false); // functionName is the name of your callback function

Since you have two densitys I imagine you may be wanting to set your own colours with scale_fill_manual.

If so you can do:

df <- data.frame(x=1:10,group=c(rep("a",5),rep("b",5)))

legend_title <- "OMG My Title"

ggplot(df, aes(x=x, fill=group)) + geom_density(alpha=.3) +   
    scale_fill_manual(legend_title,values=c("orange","red"))

One way is to stack the frames on top of each other, then you can simply raise one above the other in the stacking order. The one on top will be the one that is visible. This works best if all the frames are the same size, but with a little work you can get it to work with any sized frames.

Note: for this to work, all of the widgets for a page must have that page (ie: self) or a descendant as a parent (or master, depending on the terminology you prefer).

Here's a bit of a contrived example to show you the general concept:

try:
    import tkinter as tk                # python 3
    from tkinter import font as tkfont  # python 3
except ImportError:
    import Tkinter as tk     # python 2
    import tkFont as tkfont  # python 2

class SampleApp(tk.Tk):

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)

        self.title_font = tkfont.Font(family='Helvetica', size=18, weight="bold", slant="italic")

        # the container is where we'll stack a bunch of frames
        # on top of each other, then the one we want visible
        # will be raised above the others
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}
        for F in (StartPage, PageOne, PageTwo):
            page_name = F.__name__
            frame = F(parent=container, controller=self)
            self.frames[page_name] = frame

            # put all of the pages in the same location;
            # the one on the top of the stacking order
            # will be the one that is visible.
            frame.grid(row=0, column=0, sticky="nsew")

        self.show_frame("StartPage")

    def show_frame(self, page_name):
        '''Show a frame for the given page name'''
        frame = self.frames[page_name]
        frame.tkraise()


class StartPage(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(self, text="This is the start page", font=controller.title_font)
        label.pack(side="top", fill="x", pady=10)

        button1 = tk.Button(self, text="Go to Page One",
                            command=lambda: controller.show_frame("PageOne"))
        button2 = tk.Button(self, text="Go to Page Two",
                            command=lambda: controller.show_frame("PageTwo"))
        button1.pack()
        button2.pack()


class PageOne(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(self, text="This is page 1", font=controller.title_font)
        label.pack(side="top", fill="x", pady=10)
        button = tk.Button(self, text="Go to the start page",
                           command=lambda: controller.show_frame("StartPage"))
        button.pack()


class PageTwo(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        self.controller = controller
        label = tk.Label(self, text="This is page 2", font=controller.title_font)
        label.pack(side="top", fill="x", pady=10)
        button = tk.Button(self, text="Go to the start page",
                           command=lambda: controller.show_frame("StartPage"))
        button.pack()


if __name__ == "__main__":
    app = SampleApp()
    app.mainloop()

If you find the concept of creating instance in a class confusing, or if different pages need different arguments during construction, you can explicitly call each class separately. The loop serves mainly to illustrate the point that each class is identical.

For example, to create the classes individually you can remove the loop (for F in (StartPage, ...) with this:

self.frames["StartPage"] = StartPage(parent=container, controller=self)
self.frames["PageOne"] = PageOne(parent=container, controller=self)
self.frames["PageTwo"] = PageTwo(parent=container, controller=self)

self.frames["StartPage"].grid(row=0, column=0, sticky="nsew")
self.frames["PageOne"].grid(row=0, column=0, sticky="nsew")
self.frames["PageTwo"].grid(row=0, column=0, sticky="nsew")

Over time people have asked other questions using this code (or an online tutorial that copied this code) as a starting point. You might want to read the answers to these questions:

• Understanding parent and controller in Tkinter __init__
• Tkinter! Understanding how to switch frames
• How to get variable data from a class
• Calling functions from a Tkinter Frame to another
• How to access variables from different classes in tkinter?
• How would I make a method which is run every time a frame is shown in tkinter
• Tkinter Frame Resize
• Tkinter have code for pages in separate files
• Refresh a tkinter frame on button press

The data property allows you to send in a string. On your server side code, accept it as a string argument name "myVar" and then you can parse it out.

$.ajax({
    url: "ajax.aspx",
    data: [myVar = {id: 4, email: 'emailaddress', myArray: [1, 2, 3]}];
    success: function(response) {
    //Do Something
    },
    error: function(xhr) {
    //Do Something to handle error
    }
});

I am bit late to comment in this question but it might be useful for some other people.

You can make your android phone to work like keyboard, mouse, camera, sound streaming system, tethering device. In short what ever usb gadget you see in the market and until and unless hardware doesn't limit you. Such as speed, or gadget interface not available.

USB device is of two type, host and gadget. So gadget device acts like client and usually has usb otg interface in most of the phones. So in gadget end, you can make your phone to behave like different device at all by switching between different configuration(you are already doing it when you go into usb settings and make your device as mass storage or anything else).

But for doing all these you have to modify android kernel. If you are a android device developer you can for sure do it.

Try to use redoc-cli.

I was using bootprint-openapi by which I was generating a bunch of files (bundle.js, bundle.js.map, index.html, main.css and main.css.map) and then you can convert it into a single .html file using html-inline to generate a simple index.html file.

Then I found redoc-cli very easy to to use and output is really-2 awesome, a single and beautiful index.html file.

Installation:

npm install -g redoc-cli

Usage:

redoc-cli bundle -o index.html swagger.json

grep -rnw "some thing to grep" --include=*.{module,inc,php,js,css,html,htm} ./

With modern browsers, you can set the textContent property, see Node.textContent:

var span = document.getElementById("myspan");
span.textContent = "some text";

http://dev.mysql.com/doc/refman/5.0/en/insert-select.html

For case1:

INSERT INTO TAB_STUDENT(name_student, id_teacher_fk)
SELECT 'Joe The Student', id_teacher
  FROM TAB_TEACHER
 WHERE name_teacher = 'Professor Jack'
 LIMIT 1

For case2 you just have to do 2 separate insert statements

There is only 1 thing that fixed this for me. In the pom.xml, add the tag:

<packaging>war</packaging>

Then after saving that, when you right click on the project you should now see the "Run As... Run on Server" option showing up.

And for JavaScript source format you can use Dreamweaver JavaScript source formatting extension.(available on adobe)

Extending @marcg solution, you can normally throw and catch a checked exception in Streams; that is, compiler will ask you to catch/re-throw as is you were outside streams!!

@FunctionalInterface
public interface Predicate_WithExceptions<T, E extends Exception> {
    boolean test(T t) throws E;
}

/**
 * .filter(rethrowPredicate(t -> t.isActive()))
 */
public static <T, E extends Exception> Predicate<T> rethrowPredicate(Predicate_WithExceptions<T, E> predicate) throws E {
    return t -> {
        try {
            return predicate.test(t);
        } catch (Exception exception) {
            return throwActualException(exception);
        }
    };
}

@SuppressWarnings("unchecked")
private static <T, E extends Exception> T throwActualException(Exception exception) throws E {
    throw (E) exception;
}

Then, your example would be written as follows (adding tests to show it more clearly):

@Test
public void testPredicate() throws MyTestException {
    List<String> nonEmptyStrings = Stream.of("ciao", "")
            .filter(rethrowPredicate(s -> notEmpty(s)))
            .collect(toList());
    assertEquals(1, nonEmptyStrings.size());
    assertEquals("ciao", nonEmptyStrings.get(0));
}

private class MyTestException extends Exception { }

private boolean notEmpty(String value) throws MyTestException {
    if(value==null) {
        throw new MyTestException();
    }
    return !value.isEmpty();
}

@Test
public void testPredicateRaisingException() throws MyTestException {
    try {
        Stream.of("ciao", null)
                .filter(rethrowPredicate(s -> notEmpty(s)))
                .collect(toList());
        fail();
    } catch (MyTestException e) {
        //OK
    }
}

For getting quick profile stats on an IPython notebook. One can embed line_profiler and memory_profiler straight into their notebooks.

Another useful package is Pympler. It is a powerful profiling package that's capable to track classes,objects,functions,memory leaks etc. Examples below, Docs attached.

Get it!

!pip install line_profiler
!pip install memory_profiler
!pip install pympler

Load it!

%load_ext line_profiler
%load_ext memory_profiler

Use it!

%time

%time print('Outputs CPU time,Wall Clock time') 
#CPU times: user 2 µs, sys: 0 ns, total: 2 µs Wall time: 5.96 µs

Gives:

• CPU times: CPU level execution time
• sys times: system level execution time
• total: CPU time + system time
• Wall time: Wall Clock Time

%timeit

%timeit -r 7 -n 1000 print('Outputs execution time of the snippet') 
#1000 loops, best of 7: 7.46 ns per loop

• Gives best time out of given number of runs(r) in looping (n) times.
• Outputs details on system caching:
  • When code snippets are executed multiple times, system caches a few opearations and doesn't execute them again that may hamper the accuracy of the profile reports.

%prun

%prun -s cumulative 'Code to profile' 

Gives:

• number of function calls(ncalls)
• has entries per function call(distinct)
• time taken per call(percall)
• time elapsed till that function call(cumtime)
• name of the func/module called etc...

%memit

%memit 'Code to profile'
#peak memory: 199.45 MiB, increment: 0.00 MiB

Gives:

• Memory usage

%lprun

#Example function
def fun():
  for i in range(10):
    print(i)

#Usage: %lprun <name_of_the_function> function
%lprun -f fun fun()

Gives:

• Line wise stats

sys.getsizeof

sys.getsizeof('code to profile')
# 64 bytes

Returns the size of an object in bytes.

asizeof() from pympler

from pympler import asizeof
obj = [1,2,("hey","ha"),3]
print(asizeof.asizeof(obj,stats=4))

pympler.asizeof can be used to investigate how much memory certain Python objects consume. In contrast to sys.getsizeof, asizeof sizes objects recursively

tracker from pympler

from pympler import tracker
tr = tracker.SummaryTracker()
def fun():
  li = [1,2,3]
  di = {"ha":"haha","duh":"Umm"}
fun()
tr.print_diff()

Tracks the lifetime of a function.

Pympler package consists of a huge number of high utility functions to profile code. All of which cannot be covered here. See the documentation attached for verbose profile implementations.

Pympler doc

version for data.table based on code from dmanuge :

convNumValues<-function(ds){
  ds<-data.table(ds)
  dsnum<-data.table(data.matrix(ds))
  num_cols <- sapply(dsnum,function(x){mean(as.numeric(is.na(x)))<0.5})
  nds <- data.table(  dsnum[, .SD, .SDcols=attributes(num_cols)$names[which(num_cols)]]
                        ,ds[, .SD, .SDcols=attributes(num_cols)$names[which(!num_cols)]] )
return(nds)
}

Look into android.util.Log. It lets you write to the log with various log levels, and you can specify different tags to group the output. For example

Log.w("myApp", "no network");

will output a warning with the tag myApp and the message no network.

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

These functions have been very helpful to me - especially in setting up subscription reports; however, I noticed when using the Last Day of Current Month function posted above, it works as long as the proceeding month has the same number of days as the current month. I have worked through and tested these modifications and hope they help other developers in the future:

Date Formulas: Find the First Day of Previous Month:

DateAdd("m", -1, DateSerial(Year(Today()), Month(Today()), 1))

Find Last Day of Previous Month:

DateSerial(Year(Today()), Month(Today()), 0)

Find First Day of Current Month:

DateSerial(Year(Today()),Month(Today()),1)

Find Last Day of Current Month:

DateSerial(Year(Today()),Month(DateAdd("m", 1, Today())),0)

If you have installed Git for Windows, you should have Git Bash installed, since that comes with Git.

Use the split command in Git Bash to split a file:

• into files of size 500MB each: split myLargeFile.txt -b 500m

• into files with 10000 lines each: split myLargeFile.txt -l 10000

Tips:

• If you don't have Git/Git Bash, download at https://git-scm.com/download

• If you lost the shortcut to Git Bash, you can run it using C:\Program Files\Git\git-bash.exe

That's it!

I always like examples though...

Example:

You can see in this image that the files generated by split are named xaa, xab, xac, etc.

These names are made up of a prefix and a suffix, which you can specify. Since I didn't specify what I want the prefix or suffix to look like, the prefix defaulted to x, and the suffix defaulted to a two-character alphabetical enumeration.

Another Example:

This example demonstrates

• using a filename prefix of MySlice (instead of the default x),
• the -d flag for using numerical suffixes (instead of aa, ab, ac, etc...),
• and the option -a 5 to tell it I want the suffixes to be 5 digits long:

Iterate over dictionary (i) will return the key, then using it (i) to get the value

for i in D:
    print "key: %s, value: %s" % (i, D[i])

On Windows when you are using PowerShell you have to enclose all parameters with quotes.

So if you want to create a maven webapp archetype you would do as follows:

Prerequisites:

1. Make sure you have maven installed and have it in your PATH environment variable.

Howto:

1. Open windows powershell
2. mkdir MyWebApp
3. cd MyWebApp
4. mvn archetype:generate "-DgroupId=com.javan.dev" "-DartifactId=MyWebApp" "-DarchetypeArtifactId=maven-archetype-webapp" "-DinteractiveMode=false"

Note: This is tested only on windows 10 powershell

See the Parameter Expansion section in the Bash man page. A[@] returns the contents of the array, :1:2 takes a slice of length 2, starting at index 1.

A=( foo bar "a  b c" 42 )
B=("${A[@]:1:2}")
C=("${A[@]:1}")       # slice to the end of the array
echo "${B[@]}"        # bar a  b c
echo "${B[1]}"        # a  b c
echo "${C[@]}"        # bar a  b c 42
echo "${C[@]: -2:2}"  # a  b c 42 # The space before the - is necesssary

Note that the fact that "a b c" is one array element (and that it contains an extra space) is preserved.

In case you want to add years to specific date besides today's date using either years, or months, or days. You can do the following

var christmas2000 = new Date(2000, 12, 25); 
christmas2000.setFullYear(christmas2000.getFullYear() + 5); // using year: next 5 years
christmas2000.setFullYear(christmas2000.getMonth() + 24); // using months: next 24 months
christmas2000.setFullYear(christmas2000.getDay() + 365); // using days: next 365 months

You won't be able to do the exact thing in mySQL, the easiest thing would to probably make a view that mirrors that CTE and just select from the view. You can do it with subqueries, but that will perform really poorly. If you run into any CTEs that do recursion, I don't know how you'd be able to recreate that without using stored procedures.

EDIT: As I said in my comment, that example you posted has no need for a CTE, so you must have simplified it for the question since it can be just written as

SELECT article.*, userinfo.*, category.* FROM question
     INNER JOIN userinfo ON userinfo.user_userid=article.article_ownerid
     INNER JOIN category ON article.article_categoryid=category.catid
     WHERE article.article_isdeleted = 0
 ORDER BY article_date DESC Limit 1, 3

You can change location of legend using loc argument. https://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.legend

import matplotlib.pyplot as plt

plt.subplot(211)
plt.plot([1,2,3], label="test1")
plt.plot([3,2,1], label="test2")
# Place a legend above this subplot, expanding itself to
# fully use the given bounding box.
plt.legend(bbox_to_anchor=(0., 1.02, 1., .102), loc=3,
           ncol=2, mode="expand", borderaxespad=0.)

plt.subplot(223)
plt.plot([1,2,3], label="test1")
plt.plot([3,2,1], label="test2")
# Place a legend to the right of this smaller subplot.
plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.)

plt.show()

img = cv2.imread("/x2.jpeg")

image = cv2.resize(img, (1800, 1800))

alpha=1.5
beta=20

new_image=cv2.addWeighted(image,alpha,np.zeros(image.shape, image.dtype),0,beta)

cv2.imshow("new",new_image)
cv2.waitKey(0)
cv2.destroyAllWindows()

Here is a while loop:

while read filename
do
    echo "Printing: $filename"
    cat "$filename"
done < filenames.txt

but it's not working in IE. recommend using :nth-child(2n+1) :nth-child(2n+2)

li {_x000D_
    color: black;_x000D_
}_x000D_
li:nth-child(odd) {_x000D_
    color: #777;_x000D_
}_x000D_
li:nth-child(even) {_x000D_
    color: blue;_x000D_
}

<ul>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
</ul>

If you don't care about any child elements, e.g. optgroup, you can use empty()...

$('select').empty();

Otherwise, if you only want option elements removed, use remove().

$('select option').remove();

For a SmoothScroll with Scroll duration:

getListView().smoothScrollToPositionFromTop(position,offset,duration);

Parameters
position -> Position to scroll to
offset ---->Desired distance in pixels of position from the top of the view when scrolling is finished
duration-> Number of milliseconds to use for the scroll

Note: From API 11.

HandlerExploit's answer was what I was looking for, but My listview is quite lengthy and also with alphabet scroller. Then I found that the same function can take other parameters as well :)

Edit:(From AFDs suggestion)

To position the current selection:

int h1 = mListView.getHeight();
int h2 = listViewRow.getHeight();

mListView.smoothScrollToPositionFromTop(position, h1/2 - h2/2, duration);  

dict.iteritems() in python 2 is equivalent to dict.items() in python 3.

My use case is simpler, and fits simply your title but not your further detail.

That is, I want to install a new package which is not yet in my composer.json without updating all the other packages.

The solution here is composer require x/y

This Q repeats time and time again - a simple way to patch the json module such that serialization would support datetime.

import json
import datetime

json.JSONEncoder.default = lambda self,obj: (obj.isoformat() if isinstance(obj, datetime.datetime) else None)

Than use json serialization as you always do - this time with datetime being serialized as isoformat.

json.dumps({'created':datetime.datetime.now()})

Resulting in: '{"created": "2015-08-26T14:21:31.853855"}'

See more details and some words of caution at: StackOverflow: JSON datetime between Python and JavaScript

Add NO History Flag in the intent.

I had an index folder with 33 folders that needed all the files and subfolders removed in them. I opened a command line in the index folder and then used these commands:

for /d in (*) do rd /s /q "%a" & (
md "%a")

I separated them into two lines (hit enter after first line, and when asked for more add second line) because if entered on a single line this may not work. This command will erase each directory and then create a new one which is empty, thus removing all files and subflolders in the original directory.

As far as I remember the standard, all function declarations are considered as "extern" by default, so there is no need to specify it explicitly.

That doesn't make this keyword useless since it can also be used with variables (and it that case - it's the only solution to solve linkage problems). But with the functions - yes, it's optional.

My approach:

var urlParams;
(window.onpopstate = function () {
var match,
      pl     = /\+/g,  Regex for replacing addition symbol with a space
       search = /([^&=]+)=?([^&]*)/g,
      decode = function (s) { return decodeURIComponent(s.replace(pl, " ")); },
       query  = window.location.search.substring(1);
   urlParams = {};
   while (match = search.exec(query))
    urlParams[decode(match[1])] = decode(match[2]);
})();

function gotoItem( item ){
    var url = window.location.href;
    var separator = (url.indexOf('?') > -1) ? "&" : "?";
    var qs = "item=" + encodeURIComponent(item);
    window.location.href = url + separator + qs;
}

More compat version

function gotoItem( item ){
    var url = window.location.href;    
    url += (url.indexOf('?') > -1)?"&":"?" + "item=" + encodeURIComponent(item);
    window.location.href = url;
}

Anyone could potentially use this command to rename a field from the collection (By not using any _id):

dbName.collectionName.update({}, {$rename:{"oldFieldName":"newFieldName"}}, false, true);

see FYI

When using batch insert use the following syntax:

INSERT INTO TABLE (id, name, age) VALUES (1, "A", 19), (2, "B", 17), (3, "C", 22)
ON DUPLICATE KEY UPDATE

    ...

You may want to know why this is happening. Together with the great explanation by that other guy, find a reference of Why does my shell script choke on whitespace or other special characters? written by Gilles in Unix & Linux:

Why do I need to write "$foo"? What happens without the quotes?

$foo does not mean “take the value of the variable foo”. It means something much more complex:

• First, take the value of the variable.
• Field splitting: treat that value as a whitespace-separated list of fields, and build the resulting list. For example, if the variable contains foo * bar ? then the result of this step is the 3-element list foo, *, bar.
• Filename generation: treat each field as a glob, i.e. as a wildcard pattern, and replace it by the list of file names that match this pattern. If the pattern doesn't match any files, it is left unmodified. In our example, this results in the list containing foo, following by the list of files in the current directory, and finally bar. If the current directory is empty, the result is foo, *, bar.

Note that the result is a list of strings. There are two contexts in shell syntax: list context and string context. Field splitting and filename generation only happen in list context, but that's most of the time. Double quotes delimit a string context: the whole double-quoted string is a single string, not to be split. (Exception: "$@" to expand to the list of positional parameters, e.g. "$@" is equivalent to "$1" "$2" "$3" if there are three positional parameters. See What is the difference between $* and $@?)

The same happens to command substitution with $(foo) or with `foo`. On a side note, don't use `foo`: its quoting rules are weird and non-portable, and all modern shells support $(foo) which is absolutely equivalent except for having intuitive quoting rules.

The output of arithmetic substitution also undergoes the same expansions, but that isn't normally a concern as it only contains non-expandable characters (assuming IFS doesn't contain digits or -).

See When is double-quoting necessary? for more details about the cases when you can leave out the quotes.

Unless you mean for all this rigmarole to happen, just remember to always use double quotes around variable and command substitutions. Do take care: leaving out the quotes can lead not just to errors but to security holes.

This one is nice, but doesn't work as mmyers noticed, because of the square brackets:

Arrays.toString(objectArray).split(",")

This one is ugly but works:

Arrays.toString(objectArray).replaceFirst("^\\[", "").replaceFirst("\\]$", "").split(",")

If you use this code you must be sure that the strings returned by your objects' toString() don't contain commas.

This change only first handle in multihandle slider. In apiDoc you can see:"For example, if you specify values: [ 1, 5, 18 ] and create one custom handle, the plugin will create the other two."

Conda itself provides a quite detailed guidance about installing non-conda packages. Details can be found here: https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-pkgs.html

The basic idea is to use conda-forge. If it doesn't work, activate the environment and use pip.

If the problem you face is the menu breaking into multiple lines, you can try one of the following:

1) Try to reduce the number of menu items or their length, like removing menu items or shortening the words.

2) Reducing the padding between the menu items, like this:

.navbar .nav > li > a {
padding: 10px 15px 10px; /* Change here the second value for padding-left and padding right */
}

Default padding is 15px both sides (left and right).

If you prefer to change each individual side use:

padding-left: 7px; 
padding-right: 8px;

This setting affects the dropdown list too.

This doesn't answer the question but it could help others who don't want to mess with the CSS or using LESS variables. The two common approaches to solve this problem.

Try to verify, that your xml is wellformed and does not have a BOM. Java doesn't use BOMs.

Edit. I just noticed you were mentionning MAMP. My advice is for Windows but may be useful if you know what corresponding tools to use.

Things to try:

• Have you restarted PHP and Apache since your editing of php.ini?

• Is the php_pgsql.dll found in your php\ext directory?

• Are you running php as a module? If so, try copying the php_pgsql.dll file in the Apache\bin directory.

• Are you running PHP from the command line with a flag specifying a different php.ini file?

• You could try using a tool such as Sysinternals' Filemon to view what files are attempting to be accessed when running PHP.

• You could try using a tool such as Dependency Walker to look at the dependencies for the postgreSQL DLL, in case you have a missing dependency. Quick search brought up ldd for Unix.

That said, everybody seems to come to this page for the more general answer to your question:

Selecting a random row in SQL

Select a random row with MySQL:

SELECT column FROM table
ORDER BY RAND()
LIMIT 1

Select a random row with PostgreSQL:

SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1

Select a random row with Microsoft SQL Server:

SELECT TOP 1 column FROM table
ORDER BY NEWID()

Select a random row with IBM DB2

SELECT column, RAND() as IDX 
FROM table 
ORDER BY IDX FETCH FIRST 1 ROWS ONLY

Select a random record with Oracle:

SELECT column FROM
( SELECT column FROM table
ORDER BY dbms_random.value )
WHERE rownum = 1

Select a random row with sqlite:

SELECT column FROM table 
ORDER BY RANDOM() LIMIT 1

Deleting the file will also remove the content. See remove file.

u can check onCancelled() once then :

protected Object doInBackground(Object... x) {

while (/* condition */) {
  if (isCancelled()) break;

FYI, if you want to create an Installer package in VS2010, unfortunately it only targets .NET 4. To work around this, you have to add NET 4.5 as a launch condition.

Add the following in to the Launch Conditions of the installer (Right click, View, Launch Conditions).

In "Search Target Machine", right click and select "Add Registry Search".

Property: REGISTRYVALUE1
RegKey: Software\Microsoft\NET Framework Setup\NDP\v4\Full
Root: vsdrrHKLM
Value: Release

Add new "Launch Condition":

Condition: REGISTRYVALUE1>="#378389"
InstallUrl: http://www.microsoft.com/en-gb/download/details.aspx?id=30653
Message: Setup requires .NET Framework 4.5 to be installed.

Where:

378389 = .NET Framework 4.5

378675 = .NET Framework 4.5.1 installed with Windows 8.1

378758 = .NET Framework 4.5.1 installed on Windows 8, Windows 7 SP1, or Windows Vista SP2

379893 = .NET Framework 4.5.2

right, you have to manually enumerate keyset till the end of the linkedlist, then retrieve the entry by key and return this entry.

Change this property and try this at design time:

FormBorderStyle = FormBorderStyle.FixedDialog;

Designer view before the change:

I know this question is quite old, but I have not seen this solution here before:

If you rewrite the <body> tag to.

<body oncontextmenu="return false;">

you can prevent the right click without using javascript.

However, you can't prevent keyboard shortcuts with HTML. For this, you must use Javascript.

Simple code in javascript to merge two linked list inplace.

function mergeLists(l1, l2) {
    let head = new ListNode(0); //dummy
    let curr = head;
    while(l1 && l2) {
        if(l2.val >= l1.val) {
            curr.next = l1;
            l1 = l1.next;
        } else {
            curr.next = l2;
            l2=l2.next
        }
        curr = curr.next;
    }
    if(!l1){
        curr.next=l2;
    }
    if(!l2){
        curr.next=l1;
    } 
    return head.next;
}

You can try hfexcel Human Friendly object-oriented python library based on XlsxWriter:

from hfexcel import HFExcel

hf_workbook = HFExcel.hf_workbook('example.xlsx', set_default_styles=False)

hf_workbook.add_style(
    "headline", 
    {
       "bold": 1,
        "font_size": 14,
        "font": "Arial",
        "align": "center"
    }
)

sheet1 = hf_workbook.add_sheet("sheet1", name="Example Sheet 1")

column1, _ = sheet1.add_column('headline', name='Column 1', width=2)
column1.add_row(data='Column 1 Row 1')
column1.add_row(data='Column 1 Row 2')

column2, _ = sheet1.add_column(name='Column 2')
column2.add_row(data='Column 2 Row 1')
column2.add_row(data='Column 2 Row 2')


column3, _ = sheet1.add_column(name='Column 3')
column3.add_row(data='Column 3 Row 1')
column3.add_row(data='Column 3 Row 2')

# In order to get a row with coordinates:
# sheet[column_index][row_index] => row
print(sheet1[1][1].data)
assert(sheet1[1][1].data == 'Column 2 Row 2')

hf_workbook.save()

You can do it like that 2>&1:

 command > file 2>&1

When you go to a stream url, you get offered a file. feed this file to a parser to extract the contents out of it. the file is (usually) plain text and contains the url to play.

if you want to open all your .cpp files with one command, and have the window split in as many tiles as opened files, you can use:

vim -o $(find name ".cpp")

if you want to include a template in the place you are, you can use:

:r ~/myHeaderTemplate 

will import the file "myHeaderTemplate in the place the cursor was before starting the command.

you can conversely select visually some code and save it to a file

1. select visually,
2. add w ~/myPartialfile.txt

when you select visualy, after type ":" in order to enter a command, you'll see "'<,'>" appear after the ":"

'<,'>w ~/myfile $

^ if you add "~/myfile" to the command, the selected part of the file will be saved to myfile.

if you're editing a file an want to copy it :

:saveas newFileWithNewName 

Here is Bjarne Stroustrup's wordings,

In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.

If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

You can also change standard fonts with setTextAppearance (requires API 16), see https://stackoverflow.com/a/36301508/2914140:

<style name="styleA">
    <item name="android:fontFamily">sans-serif</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textColor">?android:attr/textColorPrimary</item>
</style>
<style name="styleB">
    <item name="android:fontFamily">sans-serif-light</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">?android:attr/textColorTertiary</item>
</style>


if(condition){
    TextViewCompat.setTextAppearance(textView, R.style.styleA);
} else {
    TextViewCompat.setTextAppearance(textView,R.style.styleB);
}

Let's start with a qualitative description of what we want to do (much of this is said in Ben Straub's answer). We've made some number of commits, five of which changed a given file, and we want to revert the file to one of the previous versions. First of all, git doesn't keep version numbers for individual files. It just tracks content - a commit is essentially a snapshot of the work tree, along with some metadata (e.g. commit message). So, we have to know which commit has the version of the file we want. Once we know that, we'll need to make a new commit reverting the file to that state. (We can't just muck around with history, because we've already pushed this content, and editing history messes with everyone else.)

So let's start with finding the right commit. You can see the commits which have made modifications to given file(s) very easily:

git log path/to/file

If your commit messages aren't good enough, and you need to see what was done to the file in each commit, use the -p/--patch option:

git log -p path/to/file

Or, if you prefer the graphical view of gitk

gitk path/to/file

You can also do this once you've started gitk through the view menu; one of the options for a view is a list of paths to include.

Either way, you'll be able to find the SHA1 (hash) of the commit with the version of the file you want. Now, all you have to do is this:

# get the version of the file from the given commit
git checkout <commit> path/to/file
# and commit this modification
git commit

(The checkout command first reads the file into the index, then copies it into the work tree, so there's no need to use git add to add it to the index in preparation for committing.)

If your file may not have a simple history (e.g. renames and copies), see VonC's excellent comment. git can be directed to search more carefully for such things, at the expense of speed. If you're confident the history's simple, you needn't bother.

Better make the google object convert as a javascript readable object first.

Create two functions like below and call it passing google map return object.

function getShortAddressObject(object) {
             let address = {};
             const address_components = object[0].address_components;
             address_components.forEach(element => {
                 address[element.types[0]] = element.short_name;
             });
             return address;
 }

 function getLongAddressObject(object) {
             let address = {};
             const address_components = object[0].address_components;
             address_components.forEach(element => {
                 address[element.types[0]] = element.long_name;
             });
             return address;
 }

Then user can access names like below.

var addressObj = getLongAddressObject(object);
var country = addressObj.country; //Sri Lanka

All address parts are like below.

administrative_area_level_1: "Western Province"
administrative_area_level_2: "Colombo"
country: "Sri Lanka"
locality: "xxxx xxxxx"
political: "xxxxx"
route: "xxxxx - xxxxx Road"
street_number: "No:00000"

As others mentioned using epel gives a really outdated version, here is a little script I just wrote instead to add to the CI pipeline or pass it to ec2 user-data to install the latest version of node, simply replace the version with what you want, and the appropriate distro of Linux you are using.

The following example is for amazon-Linux-2-AMI

#!/bin/bash

version='v14.13.1'
distro='linux-x64'
package_name="node-$version-$distro"
package_location="/usr/local/lib/"

curl -O https://nodejs.org/download/release/latest/$package_name.tar.gz
tar -xvf $package_name.tar.gz -C $package_location
rm -rfv $package_name.tar.gz

echo "export PATH=$package_location/$package_name/bin:\$PATH" >> ~/.profile

if you want to test it in the same shell simply run

. ~/.profile

Another good option for handling this kind of option is the pprint module, which (among other things) pretty prints long lists with one element per line:

>>> import sys
>>> import pprint
>>> pprint.pprint(sys.path)
['',
 '/usr/lib/python27.zip',
 '/usr/lib/python2.7',
 '/usr/lib/python2.7/plat-linux2',
 '/usr/lib/python2.7/lib-tk',
 '/usr/lib/python2.7/lib-old',
 '/usr/lib/python2.7/lib-dynload',
 '/usr/lib/python2.7/site-packages',
 '/usr/lib/python2.7/site-packages/PIL',
 '/usr/lib/python2.7/site-packages/gst-0.10',
 '/usr/lib/python2.7/site-packages/gtk-2.0',
 '/usr/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg-info',
 '/usr/lib/python2.7/site-packages/webkit-1.0']
>>> 

I recommend the SwifterSwift Library. However, if you don't want to use the entire library and all its great additions you can just make use of their extension of Dictionary:

Swift 3+

public extension Dictionary {
    public static func +=(lhs: inout [Key: Value], rhs: [Key: Value]) {
        rhs.forEach({ lhs[$0] = $1})
    }
}

Basically, with prepared statements the data coming in from a potential hacker is treated as data - and there's no way it can be intermixed with your application SQL and/or be interpreted as SQL (which can happen when data passed in is placed directly into your application SQL).

This is because prepared statements "prepare" the SQL query first to find an efficient query plan, and send the actual values that presumably come in from a form later - at that time the query is actually executed.

I use locate to find the .so files for boost_filesystem and boost_system

locate libboost_filesystem
locate libboost_system

Then link .so files to /usr/lib and rename to .so

sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_filesystem.so.1.65.1 /usr/lib/libboost_filesystem.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_system.so.1.65.1 /usr/lib/libboost_system.so

Done! R package velocyto.R was successfully installed!

Use two <input type=file> elements instead, without the multiple attribute.

try to add #include "stdafx.h" before #include "iostream"

The below solution worked for me in Ubuntu 20.04

Logs stored in: /var/lib/docker/containers/<container id>/<container id>-json.log

To know container Id: $ docker ps

In case you have a school server where the pupils worked a lot. You can just clean up the mess by:

delete from user where User != 'root' and User != 'admin';
delete from db where User != 'root' and User != 'admin';

delete from tables_priv;
delete from columns_priv;

flush privileges;

A very simple solution is put the below code in your .htaccess. I had the same issue and it solve my problem.

<IfModule mod_alias.c>
    RedirectMatch 403 favicon.ico
</IfModule>

Reference: http://perishablepress.com/block-favicon-url-404-requests/

To help understand what do $#, $0 and $1, ..., $n do, I use this script:

#!/bin/bash

for ((i=0; i<=$#; i++)); do
  echo "parameter $i --> ${!i}"
done

Running it returns a representative output:

$ ./myparams.sh "hello" "how are you" "i am fine"
parameter 0 --> myparams.sh
parameter 1 --> hello
parameter 2 --> how are you
parameter 3 --> i am fine

Also note, if you have explicitly granted:

CONNECT ON DATABASE xxx TO GROUP ,

you will need to revoke this separately from DROP OWNED BY, using:

REVOKE CONNECT ON DATABASE xxx FROM GROUP

Using the so called f strings:

answer = True
myvar = f"the answer is {answer}"

Then if I do

print(myvar)

I will get:

the answer is True

I like f strings because one does not have to worry about the order in which the variables will appear in the printed text, which helps in case one has multiple variables to be printed as strings.

Found the solution here

Lets say you have span1 as <span id='span1'>my text</span>
text change events can be captured with:

$(document).ready(function(){
    $("#span1").on('DOMSubtreeModified',function(){
         // text change handler
     });

 });
 

You can use $query->getSingleResult(), which will throw an exception if more than one result are found, or if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L791)

There's also the less famous $query->getOneOrNullResult() which will throw an exception if more than one result are found, and return null if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L752)

Note setValue only works if there are already predefined set of values for the selectize control ( ex. select field ), for controls where the value could be dynamic ( ex. user can add values on the fly, textbox field ) setValue ain't gonna work.

Use createItem functon instead for adding and setting the current value of the selectize field

ex.

$selectize[ 0 ].selectize.clear(); // Clear existing entries
for ( var i = 0 ; i < data_source.length ; i++ ) // data_source is a dynamic source of data
    $selectize[ 0 ].selectize.createItem( data_source[ i ] , false ); // false means don't trigger dropdown

The MetaWhere plugin is completely amazing.

Easily mix OR's and AND's, join conditions on any association, and even specify OUTER JOIN's!

Post.where({sharing_level: Post::Sharing[:everyone]} | ({sharing_level: Post::Sharing[:friends]} & {user: {followers: current_user} }).joins(:user.outer => :followers.outer}

If you use the Eclipse "New Android Project" wizard in a recent ADT bundle, you'll automatically get tabs implemented as a Fragments. This makes the conversion of your application to the tablet format much easier in the future.

For simple single screen layouts you may still use Activity.

I had the same problem while connecting from Android client to Kurento server. Kurento server use jks certificates, so I had to convert pem to it. As input for conversion I used cert.pem file and it lead to such errors. But if use fullchain.pem instead of cert.pem - all is OK.

You can also try: (I tried this and it worked for me)

SELECT ISNULL((SELECT SUM(columnA) FROM my_table WHERE columnB = 1),0)) INTO res;

I like a combination of Gaurav's and user2550946's answer best, but would like to add two more aspects:

1. Don't use JAVA_OPTS, instead use CATALINA_OPTS. This will be used solely for starting tomcat, not for shutting it down. Typically you want more memory when starting tomcat, but the shutdown process (which just spins up, tells tomcat to shut down and then ends again) doesn't need any specifically tuned resources. In fact, shutdown can even fail if some ridiculous amount of memory is not available from the OS anymore.

2. On production systems, my recommentation is to claim the maximum allowed memory immediately. Because if you anticipate that the memory will be required sooner or later, you don't want to discover it not being available at 3am in the night - rather when you start up the server. Thus, set -Xmx and -Xms to the same value in production systems. (This makes my aspect 1 even more relevant)

Or, in one line, here's my recommendation:

set "CATALINA_OPTS=%CATALINA_OPTS% -Xms1024M -Xmx1024M"

Thanks.I changed heap space from 2000MB to 1024MB and it worked...

I've actually found that in most of my cases, just stripping out those characters is much simpler:

s = mystring.decode('ascii', 'ignore')

As Darin says, you can read from the input stream - but I'd avoid relying on all the data being available in a single go. If you're using .NET 4 this is simple:

MemoryStream target = new MemoryStream();
model.File.InputStream.CopyTo(target);
byte[] data = target.ToArray();

It's easy enough to write the equivalent of CopyTo in .NET 3.5 if you want. The important part is that you read from HttpPostedFileBase.InputStream.

For efficient purposes you could check whether the stream returned is already a MemoryStream:

byte[] data;
using (Stream inputStream = model.File.InputStream)
{
    MemoryStream memoryStream = inputStream as MemoryStream;
    if (memoryStream == null)
    {
        memoryStream = new MemoryStream();
        inputStream.CopyTo(memoryStream);
    }
    data = memoryStream.ToArray();
}

If your problem is like the following while using Google Chrome:

[XMLHttpRequest cannot load file. Received an invalid response. Origin 'null' is therefore not allowed access.]

Then create a batch file by following these steps:

Open notepad in Desktop.

1. Just copy and paste the followings in your currently opened notepad file:

start "chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files exit

1. Note: In the previous line, Replace the full absolute address with your location of chrome installation. [To find it...Right click your short cut of chrome.exe link or icon and Click on Properties and copy-paste the target link][Remember : start to files in one line, & exit in another line by pressing enter]
2. Save the file as fileName.bat [Very important: .bat]
3. If you want to change the file later then right-click on the .bat file and click on edit. After modifying, save the file.

This will do what? It will open Chrome.exe with file access. Now, from any location in your computer, browse your html files with Google Chrome. I hope this will solve the XMLHttpRequest problem.

Keep in mind : Just use the shortcut bat file to open Chrome when you require it. Tell me if it solves your problem. I had a similar problem and I solved it in this way. Thanks.

A hard reset will also resolve the problem

git reset --hard origin/master

python now points to python3, if you need python 2 then do: brew install python@2 and then in your .zshrc or .bashrc file export PATH="/usr/local/opt/python@2/libexec/bin:$PATH" Now, pyhon --version = Python 2.7.14 and python3 --version = Python 3.6.4. That's the behavior I'm used to seeing in my terminal.

The ISO week suggested by others is a good one, but it might not fit your needs. It assumes each week begins with a Monday, which leads to some interesting anomalies at the beginning and end of the year.

If you'd rather use a definition that says week 1 is always January 1 through January 7, regardless of the day of the week, use a derivation like this:

>>> testdate=datetime.datetime(2010,6,16)
>>> print(((testdate - datetime.datetime(testdate.year,1,1)).days // 7) + 1)
24

With Yglu, you can write your example as:

paths:
  root: /path/to/root/
  patha: !? .paths.root + a
  pathb: !? .paths.root + b
  pathc: !? .paths.root + c

Disclaimer: I am the author of Yglu.

Instance methods are defined inside a class definition block. Class methods are defined as singleton methods on the singleton class of a class, also informally known as the "metaclass" or "eigenclass". private is not a keyword, but a method (Module#private).

This is a call to method self#private/A#private which "toggles" private access on for all forthcoming instance method definitions until toggled otherwise:

class A
  private
    def instance_method_1; end
    def instance_method_2; end
    # .. and so forth
end

As noted earlier, class methods are really singleton methods defined on the singleton class.

def A.class_method; end

Or using a special syntax to open the definition body of the anonymous, singleton class of A:

class << A
  def class_method; end
end

The receiver of the "message private" - self - inside class A is the class object A. self inside the class << A block is another object, the singleton class.

The following example is in reality calling two different methods called private, using two different recipients or targets for the call. In the first part, we define a private instance method ("on class A"), in the latter we define a private class method (is in fact a singleton method on the singleton class object of A).

class A
  # self is A and private call "A.private()"
  private def instance_method; end

  class << self
    # self is A's singleton class and private call "A.singleton_class.private()"
    private def class_method; end
  end
end

Now, rewrite this example a bit:

class A
  private
    def self.class_method; end
end

Can you see the mistake [that Ruby language designers] made? You toggle on private access for all forthcoming instance methods of A, but proceed to declare a singleton method on a different class, the singleton class.

Try using:

finish();

at the end of activity. It will redirect you to your previous activity.

I'd like to report a bug regarding the section Source of data to search in the first answer when using en dash (–) or em dash (—) within the filename.

More specifically, if you are about to use the first option - filenames specified as arguments, the file won't be found. As soon as you use either option 2 - stdin via redirection or 3 - data stream from a pipe, findstr will find the file.

For example, this simple batch script:

echo off
chcp 1250 > nul
set INTEXTFILE1=filename with – dash.txt
set INTEXTFILE2=filename with — dash.txt

rem 3 way of findstr use with en dashed filename
echo.
echo Filename with en dash:
echo.
echo 1. As argument
findstr . "%INTEXTFILE1%"
echo.
echo 2. As stdin via redirection
findstr . < "%INTEXTFILE1%"
echo.
echo 3. As datastream from a pipe
type "%INTEXTFILE1%" | findstr .
echo.
echo.
rem The same set of operations with em dashed filename
echo Filename with em dash:
echo.
echo 1. As argument
findstr . "%INTEXTFILE2%"
echo.
echo 2. As stdin via redirection
findstr . < "%INTEXTFILE2%"
echo.
echo 3. As datastream from a pipe
type "%INTEXTFILE2%" | findstr .
echo.

pause

will print:

Filename with en dash:

1. As argument
   FINDSTR: Cannot open filename with - dash.txt

2. As stdin via redirection
   I am the file with an en dash.

3. As datastream from a pipe
   I am the file with an en dash.

Filename with em dash:

1. As argument
   FINDSTR: Cannot open filename with - dash.txt

2. As stdin via redirection
   I am the file with an em dash.

3. As datastream from a pipe
   I am the file with an em dash.

Hope it helps.

The reference to 480px has been removed. Instead it says:

/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */

There isn't a breakpoint below 768px in Bootstrap 3.

If you want to use the @screen-sm-min and other mixins then you need to be compiling with LESS, see http://getbootstrap.com/css/#grid-less

Here's a tutorial on how to use Bootstrap 3 and LESS: http://www.helloerik.com/bootstrap-3-less-workflow-tutorial

Controller code

myApp.controller('mainController', ['$scope', '$log', function($scope, $log) {
    $scope.person = {
        name:"sangeetha PH",
       address:"first Block"
    }
}]);

Directive Code

myApp.directive('searchResult',function(){
   return{
       restrict:'AECM',
       templateUrl:'directives/search.html',
       replace: true,
       scope:{
           personName:"@",
           personAddress:"@"
       }
   } 
});

USAGE

File :directives/search.html
content:

<h1>{{personName}} </h1>
<h2>{{personAddress}}</h2>

the File where we use directive

<search-result person-name="{{person.name}}" person-address="{{person.address}}"></search-result>

There is now a nice plugin for this: The Caret Plugin

Then you can get the position using $("#myTextBox").caret() or set it via $("#myTextBox").caret(position)

The below JavaScript code sends "text" to be spoken/converted to mp3 audio to google cloud text-to-speech API and gets mp3 audio content as response back.

 var text-to-speech = function(state) {
    const url = 'https://texttospeech.googleapis.com/v1beta1/text:synthesize?key=GOOGLE_API_KEY'
    const data = {
      'input':{
         'text':'Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.'
      },
      'voice':{
         'languageCode':'en-gb',
         'name':'en-GB-Standard-A',
         'ssmlGender':'FEMALE'
      },
      'audioConfig':{
      'audioEncoding':'MP3'
      }
     };
     const otherparam={
        headers:{
           "content-type":"application/json; charset=UTF-8"
        },
        body:JSON.stringify(data),
        method:"POST"
     };
    fetch(url,otherparam)
    .then(data=>{return data.json()})
    .then(res=>{console.log(res.audioContent); })
    .catch(error=>{console.log(error);state.onError(error)})
  };

You can use @JsonFormat annotation with shape as STRING on your BigDecimal variables. Refer below:

 import com.fasterxml.jackson.annotation.JsonFormat;

  class YourObjectClass {

      @JsonFormat(shape=JsonFormat.Shape.STRING)
      private BigDecimal yourVariable;

 }

As far as I know, currently (Android Studio 2.3) there is no way to do this.

As per Android Studio documentation:

"Note: Only one debugger can be connected to your device at a time."

When you attempt to connect Android Device Monitor it disconnects Android Studio's debug session and vice versa, when you attempt to connect Android Studio's debugger, it disconnects Android Device Monitor.

Fortunately the new version of Android Studio (3.0) will feature a Device File Explorer that will allow you to pull files from within Android Studio without the need to open the Android Device Monitor which should resolve the problem.

A property, when it has no definition, is undefined. null is an object. It's type is null. undefined is not an object, its type is undefined.

This is a good article explaining the difference and also giving some examples.

null vs undefined

I mostly use this function:

cf() {
  cd "$(osascript -e 'tell app "Finder" to POSIX path of (insertion location as alias)')"
}

You could also assign a shortcut to a script like the ones below.

Reuse an existing tab or create a new window (Terminal):

tell application "Finder" to set p to POSIX path of (insertion location as alias)
tell application "Terminal"
    if (exists window 1) and not busy of window 1 then
        do script "cd " & quoted form of p in window 1
    else
        do script "cd " & quoted form of p
    end if
    activate
end tell

Reuse an existing tab or create a new tab (Terminal):

tell application "Finder" to set p to POSIX path of (insertion location as alias)
tell application "Terminal"
    if not (exists window 1) then reopen
    activate
    if busy of window 1 then
        tell application "System Events" to keystroke "t" using command down
    end if
    do script "cd " & quoted form of p in window 1
end tell

Always create a new tab (iTerm 2):

tell application "Finder" to set p to POSIX path of (insertion location as alias)
tell application "iTerm"
    if exists current terminal then
        current terminal
    else
        make new terminal
    end if
    tell (launch session "Default") of result to write text "cd " & quoted form of p
    activate
end tell

The first two scripts have two advantages compared to the services added in 10.7:

• They use the folder on the title bar instead of requiring you to select a folder first.
• They reuse the frontmost tab if it is not busy, e.g. running a command, displaying a man page, or running emacs.

The underlying issue is using max-device-width vs plain old max-width.

Using the "device" keyword targets physical dimension of the screen, not the width of the browser window.

For example:

@media only screen and (max-device-width: 480px) {
    /* STYLES HERE for DEVICES with physical max-screen width of 480px */
}

Versus

@media only screen and (max-width: 480px) {
    /* STYLES HERE for BROWSER WINDOWS with a max-width of 480px. 
       This will work on desktops when the window is narrowed.  */
}

You should use thenReturn or doReturn when you know the return value at the time you mock a method call. This defined value is returned when you invoke the mocked method.

thenReturn(T value) Sets a return value to be returned when the method is called.

@Test
public void test_return() throws Exception {
    Dummy dummy = mock(Dummy.class);
    int returnValue = 5;

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenReturn(returnValue);
    doReturn(returnValue).when(dummy).stringLength("dummy");
}

Answer is used when you need to do additional actions when a mocked method is invoked, e.g. when you need to compute the return value based on the parameters of this method call.

Use doAnswer() when you want to stub a void method with generic Answer.

Answer specifies an action that is executed and a return value that is returned when you interact with the mock.

@Test
public void test_answer() throws Exception {
    Dummy dummy = mock(Dummy.class);
    Answer<Integer> answer = new Answer<Integer>() {
        public Integer answer(InvocationOnMock invocation) throws Throwable {
            String string = invocation.getArgumentAt(0, String.class);
            return string.length() * 2;
        }
    };

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenAnswer(answer);
    doAnswer(answer).when(dummy).stringLength("dummy");
}

This should answer that question, and then some.

The second line, if (obj.GetType() == typeof(ClassA)) {}, is faster, for those that don't want to read the article.

(Be aware that they don't do the same thing)

Your call_python_file.php should look like this:

<?php
    $item='Everything is awesome!!';
    $tmp = exec("py.py $item");
    echo $tmp;
?>

This executes the python script and outputs the result to the browser. While in your python script the (sys.argv[1:]) variable will bring in all your arguments. To display the argv as a string for wherever your php is pulling from so if you want to do a text area:

import sys

list1 = ' '.join(sys.argv[1:])

def main():
  print list1

if __name__ == '__main__':
    main()

uint32_t is defined in the standard, in

18.4.1 Header <cstdint> synopsis [cstdint.syn]

namespace std {
//...
typedef unsigned integer type uint32_t; // optional
//...

uint32 is not, it's a shortcut provided by some compilers (probably as typedef uint32_t uint32) for ease of use.

I would do this as an iterative process.

1) Dump the table to a flat file to work with.

2) Write a simple program to break up your Names using a space as separator where firsts token is the first name, if there are 3 token then token 2 is middle name and token 3 is last name. If there are 2 tokens then the second token is the last name. (Perl, Java, or C/C++, language doesn't matter)

3) Eyeball the results. Look for names that don't fit this rule.

4) Using that example, create a new rule to handle that exception...

5) Rinse and Repeat

Eventually you will get a program that fixes all your data.

The element.getBoundingClientRect() method will return the proper coordinates of an element relative to the viewport regardless of whether the svg has been scaled and/or translated.

See this question and answer.

While getBBox() works for an untransformed space, if scale and translation have been applied to the layout then it will no longer be accurate. The getBoundingClientRect() function has worked well for me in a force layout project when pan and zoom are in effect, where I wanted to attach HTML Div elements as labels to the nodes instead of using SVG Text elements.

Cardinality refers to the uniqueness of data contained in a column. If a column has a lot of duplicate data (e.g. a column that stores either "true" or "false"), it has low cardinality, but if the values are highly unique (e.g. Social Security numbers), it has high cardinality.

 public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

    FrameLayout root;


    public ViewHolder(View itemView) {
        super(itemView);

        root = (FrameLayout) itemView.findViewById(R.id.root);
        root.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        LogUtils.errorLog("POS_CLICKED: ",""+getAdapterPosition());
    }
}

I've found that binding an element.click in a function that happens more than once will queue it so next time you click it, it will trigger as many times as the binding function was executed. Newcomer mistake probably on my end but I hope it helps. TL,DR: Make sure you bind all clicks on a setup function that only happens once.

The other answers address the main thrust of the question, but just to comment on this part...

PS C:\> [array]$foo = @("bar")
PS C:\> $foo -eq $null
PS C:\>

How can "-eq $null" give no results? It's either $null or it's not.

It's confusing at first, but that is giving you the result of $foo -eq $null, it's just that the result has no displayable representation.

Since $foo holds an array, $foo -eq $null means "return an array containing the elements of $foo that are equal to $null". Are there any elements of $foo that are equal to $null? No, so $foo -eq $null should return an empty array. That's exactly what it does, the problem is that when an empty array is displayed at the console you see...nothing...

PS> @()
PS> 

The array is still there, even if you can't see its elements...

PS> @().GetType()

We can use similar commands to confirm that $foo -eq $null is returning an array that we're not able to "see"...

PS> $foo -eq $null
PS> ($foo -eq $null).GetType()

Note that I am calling the Array.GetValue method instead of using the indexer (i.e. ($foo -eq $null)[0]) because the latter returns $null for invalid indices and there's no way to distinguish them from a valid index that happens to contain $null.

We see similar behavior if we test for $null in/against an array that contains $null elements...

PS> $bar = @($null)
PS> $bar -eq $null
PS> ($bar -eq $null).GetType()

IsPublic IsSerial Name                                     BaseType

In this case, $bar -eq $null returns an array containing one element, $null, which has no visual representation at the console...

As far as I can see from the implementation at https://github.com/angular/angular/blob/master/packages/common/http/src/params.ts

You must provide values separately - You are not able to avoid your loop.

There is also a constructor which takes a string as a parameter, but it is in form param=value&param2=value2 so there is no deal for You (in both cases you will finish with looping your object).

You can always report an issue/feature request to angular, what I strongly advise: https://github.com/angular/angular/issues

PS: Remember about difference between set and append methods ;)

This post asked a similar question and used LINQ to solve it, maybe it will help you out too.

string s1 = "1;2;3;4;5;6;7;8;9;10;11;12";
int[] ia = s1.Split(';').Select(n => Convert.ToInt32(n)).ToArray();

In JavaScript, use split to help out, and catch any negative digits as well:

'-1,2,-3'.match(/(-?\d+)(,\s*-?\d+)*/)[0].split(',');
// ["-1", "2", "-3"]
// may need trimming if digits are space-separated

After much research, I found the easiest method is to pass all kinds of variables easily.

In the server script, you have two variables, and you are trying to send them to the client scripts:

$php_var1 ="Hello world";
$php_var2 ="Helloow";
echo '<script>';
echo 'var js_variable1= ' . json_encode($php_var1) . ';';
echo 'var js_variable2= ' . json_encode($php_var2) . ';';
echo '</script>';

In any of your JavaScript code called on the page, simply call those variables.

If you're getting this error because you're purposefully trying to build to Java 6, but you have Java 7 elsewhere in Eclipse, then it may be because you are referencing a Java 7 tools.jar in a Java 6 environment.

You'll need to install the JDK 6 (not JRE) and add the JRE 6 tools.jar as a User Entry in the Classpath of the build configuration, listed above the JRE 7 tools.jar.

As the other answers state, you need to select an active scheme to something that is not a simulator, i.e. a device that's connected to your mac.

If you have no device connected to the mac then selecting "Generic IOS Device" works also.

I figured you are using PHP but not mentioned (edited). I found this question by searching internet and since I got solution working , for those who use nodejs here is a simple solution using scan :

  var dynamoClient = new AWS.DynamoDB.DocumentClient();
  var params = {
    TableName: config.dynamoClient.tableName, // give it your table name 
    Select: "ALL_ATTRIBUTES"
  };

  dynamoClient.scan(params, function(err, data) {
    if (err) {
       console.error("Unable to read item. Error JSON:", JSON.stringify(err, null, 2));
    } else {
       console.log("GetItem succeeded:", JSON.stringify(data, null, 2));
    }
  });

I assume same code can be translated to PHP too using different AWS SDK

Write the code in your viewDidLoad()

self.view.layer.borderColor = anyColor().CGColor

And you can set Color with RGB

func anyColor() -> UIColor {
    return UIColor(red: 0.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 1.0)
}

You can just read the data into a list and insert the new record where you want.

names = []
with open('names.txt', 'r+') as fd:
    for line in fd:
        names.append(line.split(' ')[-1].strip())

    names.insert(2, "Charlie") # element 2 will be 3. in your list
    fd.seek(0)
    fd.truncate()

    for i in xrange(len(names)):
        fd.write("%d. %s\n" %(i + 1, names[i]))

Achieves the same ends as Mark Reed's answer, but uses a much safer approach that doesn't misbehave in a number of scenarios:

1. Parent branch's last commit is a merge, making the column show - not *
2. Commit message contains branch name
3. Commit message contains *

<input type="number" step="1" ...

By adding the step attribute, you restrict input to integers.

Of course you should always validate on the server as well. Except under carefully controlled conditions, everything received from a client needs to be treated as suspect.

I has able to choose a simplier solution > Add a new Headers to the defaults options merge or load by your api get (or other) function.

get(endpoint: string, params?: any, options?: RequestOptions) {
  if (!options) {
    options = new RequestOptions();
    options.headers = new Headers( { "Accept": "application/json" } ); <<<<
  }
  // [...] 
}

Of course you can externalize this Headers in default options or whatever in your class. This is in the Ionic generated api.ts @Injectable() export class API {}

It is very quick and it work for me. I didn't want json/ld format.

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_
table, tbody, tr, td {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  border: 0;_x000D_
  border-spacing: 0;_x000D_
}_x000D_
_x000D_
.a, .c {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  background-color: #F77;_x000D_
}_x000D_
_x000D_
.a {_x000D_
  min-width: 10px;_x000D_
  width: 20px;_x000D_
  max-width: 20px;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  min-width: 40px;_x000D_
  width: 45px;_x000D_
  max-width: 45px;_x000D_
}_x000D_
_x000D_
.c {}

<table>_x000D_
  <tr>_x000D_
    <td class="a">A</td>_x000D_
    <td class="b">B</td>_x000D_
    <td class="c">C</td>_x000D_
  </tr>_x000D_

This will test if strings are made up of some combination or digits, the dollar sign, and a commas. Is that what you're looking for?

import re

s1 = 'Testing string'
s2 = '1234,12345$'

regex = re.compile('[0-9,$]+$')

if ( regex.match(s1) ):
   print "s1 matched"
else:
   print "s1 didn't match"

if ( regex.match(s2) ):
   print "s2 matched"
else:
   print "s2 didn't match"

Use selectors like CSS3

$("banner.html>div:first-child").append(data);

I just noticed that top is available in adb, so you can do things like

  adb shell
  top -m 5

to monitor the top five CPU hogging processes.

Or

  adb shell top -m 5 -s cpu -n 20 |tee top.log

to record this for one minute and collect the output to a file on your computer.

No, there is no "previous sibling" selector.

On a related note, ~ is for general successor sibling (meaning the element comes after this one, but not necessarily immediately after) and is a CSS3 selector. + is for next sibling and is CSS2.1.

See Adjacent sibling combinator from Selectors Level 3 and 5.7 Adjacent sibling selectors from Cascading Style Sheets Level 2 Revision 1 (CSS 2.1) Specification.

I am aware there are existing answers which solves the problem. For those who are new to git, As of 02/11/2021, The default branch in git is "main" not "master" branch, The command will be

There is no directive for ng-else

You can use ng-if to achieve if(){..} else{..} in angularJs.

For your current situation,

<div ng-if="data.id == 5">
<!-- If block -->
</div>
<div ng-if="data.id != 5">
<!-- Your Else Block -->
</div>

A new library called ts-optchain provides this functionality, and unlike lodash' solution, it also keeps your types safe, here is a sample of how it is used (taken from the readme):

import { oc } from 'ts-optchain';

interface I {
  a?: string;
  b?: {
    d?: string;
  };
  c?: Array<{
    u?: {
      v?: number;
    };
  }>;
  e?: {
    f?: string;
    g?: () => string;
  };
}

const x: I = {
  a: 'hello',
  b: {
    d: 'world',
  },
  c: [{ u: { v: -100 } }, { u: { v: 200 } }, {}, { u: { v: -300 } }],
};

// Here are a few examples of deep object traversal using (a) optional chaining vs
// (b) logic expressions. Each of the following pairs are equivalent in
// result. Note how the benefits of optional chaining accrue with
// the depth and complexity of the traversal.

oc(x).a(); // 'hello'
x.a;

oc(x).b.d(); // 'world'
x.b && x.b.d;

oc(x).c[0].u.v(); // -100
x.c && x.c[0] && x.c[0].u && x.c[0].u.v;

oc(x).c[100].u.v(); // undefined
x.c && x.c[100] && x.c[100].u && x.c[100].u.v;

oc(x).c[100].u.v(1234); // 1234
(x.c && x.c[100] && x.c[100].u && x.c[100].u.v) || 1234;

oc(x).e.f(); // undefined
x.e && x.e.f;

oc(x).e.f('optional default value'); // 'optional default value'
(x.e && x.e.f) || 'optional default value';

// NOTE: working with function value types can be risky. Additional run-time
// checks to verify that object types are functions before invocation are advised!
oc(x).e.g(() => 'Yo Yo')(); // 'Yo Yo'
((x.e && x.e.g) || (() => 'Yo Yo'))();

I think you could do something like this:

var $child = $("#parentId").append("<div></div>").children("div:last-child");

The parent #parentId is returned from the append, so add a jquery children query to it to get the last div child inserted.

$child is then the jquery wrapped child div that was added.

In my case, I found that a computed column had been added to the "included columns" of an index. Later, when an item in that table was updated, the merge statement failed with that message. The merge was in a trigger, so this was hard to track down! Removing the computed column from the index fixed it.

This errors have two common causes: The element has been deleted entirely, or the element is no longer attached to the DOM.

If you already checked if it is not your case, you could be facing the same problem as me.

The element in the DOM is not found because your page is not entirely loaded when Selenium is searching for the element. To solve that, you can put an explicit wait condition that tells Selenium to wait until the element is available to be clicked on.

from selenium.webdriver.support import expected_conditions as EC

wait = WebDriverWait(driver, 10)
element = wait.until(EC.element_to_be_clickable((By.ID, 'someid')))

See: https://selenium-python.readthedocs.io/waits.html

Just for information - if instead of an integer your required field is a single bit within a larger type, use the 'xor' operator instead:

int flags;

int flag_a = 0x01;
int flag_b = 0x02;
int flag_c = 0x04;

/* I want to flip 'flag_b' without touching 'flag_a' or 'flag_c' */
flags ^= flag_b;

/* I want to set 'flag_b' */
flags |= flag_b;

/* I want to clear (or 'reset') 'flag_b' */
flags &= ~flag_b;

/* I want to test 'flag_b' */
bool b_is_set = (flags & flag_b) != 0;

My fork of sql.js has now be merged into the original version, on kriken's repo.

The good documentation is also available on the original repo.

Original answer (outdated)

You should use the newer version of sql.js. It is a port of sqlite 3.8, has a good documentation and is actively maintained (by me). It supports prepared statements, and BLOB data type.

Generate random number between 0 to 99:

int x = arc4random()%100;

Generate random number between 500 and 1000:

int x = (arc4random()%501) + 500;

Use docker inspect.

$ docker ps # get conteiner id
$ docker inspect 4abbef615af7
[{
    "ID": "4abbef615af780f24991ccdca946cd50d2422e75f53fb15f578e14167c365989",

        "-c",
        "/start web"
    ],
    "Config": {
        "Hostname": "4abbef615af7",
...

Can get ip as follows.

$ docker inspect -format="{{ .NetworkSettings.IPAddress }}" 2a5624c52119

Try this ...

myListView.DataSource = null;
myListView.Items.Clear();

You can also use this function,

function optionDisable(selectId, optionIndices)
{
    for (var idxCount=0; idxCount<optionIndices.length;idxCount++)
    {
        document.getElementById(selectId).children[optionIndices[idxCount]].disabled="disabled";
        document.getElementById(selectId).children[optionIndices[idxCount]].style.backgroundColor = '#ccc';
        document.getElementById(selectId).children[optionIndices[idxCount]].style.color = '#f00';
    }
}

In singleton pattern you can create the singleton as an instance of a derived type, you can't do that with a static class.

Quick Example:

if( useD3D )
    IRenderer::instance = new D3DRenderer
else
    IRenderer::instance = new OpenGLRenderer

The tsc -v command run technically reads the TypeScript compiler version within the SDK directory set within the Windows Path variable. This doesn't necessarily reflect the latest version installed as the Path variable is not updated with subsequent installations.

The version that VS.NET uses to compile the TypeScript is what's in the project's configuration:

<TypeScriptToolsVersion>1.5</TypeScriptToolsVersion>

To help explain this more in detail I created the following post which has the specifics on the TypeScript versions installed, and which version VS.NET uses to compile the TypeScript files.

Which Version of TypeScript is Installed and Which Version is Visual Studio Using?

I also added a feature request on Microsoft Connect to make viewing and switching the TypeScript targeted version in VS.NET easier. This isn't really a TypeScript feature request as much as it is a VS.NET IDE enhancement.

Allow switching TypeScript configured version from Project Properties IDE

In case you run into "Too many authentication failures", specify the exact SSH key you have added to your severs ssh server:

scp -r -i /path/to/local/key [email protected]:/path/to/folder /your/local/target/dir

You can use math.ceil() to round up, and then multiply by 10

import math

def roundup(x):
    return int(math.ceil(x / 10.0)) * 10

To use just do

>>roundup(45)
50

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

$env:USERPROFILE = "C:\\Documents and Settings\\[USER]\\"

Just for those interested you can avoid writing custom function by passing NULL as last parameter (if you do not intend to do extra processing of returned data).
In this case default internal function is used.

        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, NULL);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
        res = curl_easy_perform(curl);
        curl_easy_cleanup(curl);
        fclose(fp);
    }   
    return 0;
}

You may also consider the following solution:

let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
    return html + "<li>" + item + "</li>";
        }, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;

You are repeating the y,m,d.

Instead of

gmdate('yyyy-mm-dd hh:mm:ss \G\M\T', time());  

You should use it like

gmdate('Y-m-d h:m:s \G\M\T', time());

If this problem persists, you may want to check all path values in the PATH variable (under Control Panel\System and Security\System\Advanced System Settings). It might be that some other path is invalid or contains an illegal character.

Today, I had the same problem and found a double quote in a different path value in the PATH variable. All paths after that (including a fresly installed conda) were not usable. Removing the double quote solved the problem.

// this isn't set up for good processing.  
//I don't know what data set has the expiration 
//dates of your accounts.  I assume a list.
// matchfound is a single variablethat returns true if any 1 record is expired.

bool matchFound = false;
            DateTime dateOfExpiration = DateTime.Today.AddDays(-30);
            List<DateTime> accountExpireDates = new List<DateTime>();
            foreach (DateTime date in accountExpireDates)
            {
                if (DateTime.Compare(dateOfExpiration, date) != -1)
                {
                    matchFound = true;
            }
            }

Thanks for the help everyone, rejecting the promise in .catch() solved my issue:

export function fetchVehicle(id) {
    return dispatch => {
        return dispatch({
            type: 'FETCH_VEHICLE',
            payload: fetch(`http://swapi.co/api/vehicles/${id}/`)
                .then(status)
                .then(res => res.json())    
                .catch(error => {
                    return Promise.reject()
                })
            });
    };
}


function status(res) {
    if (!res.ok) {
        throw new Error(res.statusText);
    }
    return res;
}

The std::string object returned by ss.str() is a temporary object that will have a life time limited to the expression. So you cannot assign a pointer to a temporary object without getting trash.

Now, there is one exception: if you use a const reference to get the temporary object, it is legal to use it for a wider life time. For example you should do:

#include <string>
#include <sstream>
#include <iostream>

using namespace std;

int main()
{
    stringstream ss("this is a string\n");

    string str(ss.str());

    const char* cstr1 = str.c_str();

    const std::string& resultstr = ss.str();
    const char* cstr2 = resultstr.c_str();

    cout << cstr1       // Prints correctly
        << cstr2;       // No more error : cstr2 points to resultstr memory that is still alive as we used the const reference to keep it for a time.

    system("PAUSE");

    return 0;
}

That way you get the string for a longer time.

Now, you have to know that there is a kind of optimisation called RVO that say that if the compiler see an initialization via a function call and that function return a temporary, it will not do the copy but just make the assigned value be the temporary. That way you don't need to actually use a reference, it's only if you want to be sure that it will not copy that it's necessary. So doing:

 std::string resultstr = ss.str();
 const char* cstr2 = resultstr.c_str();

would be better and simpler.

For port 80 (which was the original question), Daniel is exactly right. I recently moved to https and had to switch from iptables to a light nginx proxy managing the SSL certs. I found a useful answer along with a gist by gabrielhpugliese on how to handle that. Basically I

• Created an SSL Certificate Signing Request (CSR) via OpenSSL

  openssl genrsa 2048 > private-key.pem
  openssl req -new -key private-key.pem -out csr.pem
  

• Got the actual cert from one of these places (I happened to use Comodo)
• Installed nginx

• Changed the location in /etc/nginx/conf.d/example_ssl.conf to

  location / {
      proxy_pass http://localhost:3000;
      proxy_set_header X-Real-IP $remote_addr;
  }
  

• Formatted the cert for nginx by cat-ing the individual certs together and linked to it in my nginx example_ssl.conf file (and uncommented stuff, got rid of 'example' in the name,...)

  ssl_certificate /etc/nginx/ssl/cert_bundle.cert;
  ssl_certificate_key /etc/nginx/ssl/private-key.pem;
  

Hopefully that can save someone else some headaches. I'm sure there's a pure-node way of doing this, but nginx was quick and it worked.

I have been working on to write a custom module in Drupal 7 and got the same error:

Notice: Trying to get property of non-object

My code is something like this:

function example_node_access($node, $op, $account) {
  if ($node->type == 'page' && $op == 'update') {
    drupal_set_message('This poll has been published, you may not make changes to it.','error');
    return NODE_ACCESS_DENY;    
  }
}

Solution: I just added a condition if (is_object($sqlResult)), and everything went fine.

Here is my final code:

function mediaten_node_access($node, $op, $account) {

    if (is_object($node)){

     if ($node->type == 'page' && $op == 'update') {
       drupal_set_message('This poll has been published, you may not make changes.','error');
       return NODE_ACCESS_DENY;    
      }

    }

}

If you are having a problem with the font working I have also had this in the past and the issue I found was down to the font-family: name. This had to match what font name was actually given.

The easiest way I found to find this out was to install the font and see what display name is given.

For example, I was using Gill Sans on one project, but the actual font was called Gill Sans MT. Spacing and capitlisation was also important to get right.

Hope that helps.

There's many forms of timeout, are you after the connection timeout, request timeout or time to live (time before TCP connection stops).

The default TimeToLive on Firefox is 115s (network.http.keep-alive.timeout)

The default connection timeout on Firefox is 250s (network.http.connection-retry-timeout)

The default request timeout for Firefox is 30s (network.http.pipelining.read-timeout).

The time it takes to do an HttpRequest depends on if a connection has been made this has to be within 250s which I'm guessing you're not after. You're probably after the request timeout which I think is 30,000ms (30s) so to conclude I'd say it's timing out with a connection time out that's why you got a response back after ~150s though I haven't really tested this.

You may use this package renderer, I have written to solve this kind of problem, it's a wrapper to serve JSON, JSONP, XML, HTML etc.

I had this issue once. It turned out to be database query issue. After re-create tables and index it has been fixed.

Although it says proxy error, when you look at server log, it shows execute query timeout. This is what I had before and how I solved it.

I like to used this method the most, it will auto select the first column to the last column being used. However, if the last cell in the first row or the last cell in the first column are empty, this code will not calculate properly. Check the link for other methods to dynamically select cell range.

Sub DynamicRange()
'Best used when first column has value on last row and first row has a value in the last column

Dim sht As Worksheet
Dim LastRow As Long
Dim LastColumn As Long
Dim StartCell As Range

Set sht = Worksheets("Sheet1")
Set StartCell = Range("A1")

'Find Last Row and Column
  LastRow = sht.Cells(sht.Rows.Count, StartCell.Column).End(xlUp).Row
  LastColumn = sht.Cells(StartCell.Row, sht.Columns.Count).End(xlToLeft).Column

'Select Range
  sht.Range(StartCell, sht.Cells(LastRow, LastColumn)).Select

End Sub

Just use in the CSS whatever you would use in a fill attribute. Of course, this requires that you have defined the linear gradient somewhere in your SVG.

Here is a complete example:

rect {_x000D_
    cursor: pointer;_x000D_
    shape-rendering: crispEdges;_x000D_
    fill: url(#MyGradient);_x000D_
}

<svg width="100" height="50" version="1.1" xmlns="http://www.w3.org/2000/svg">_x000D_
      <style type="text/css">_x000D_
        rect{fill:url(#MyGradient)}_x000D_
      </style>_x000D_
      <defs>_x000D_
        <linearGradient id="MyGradient">_x000D_
          <stop offset="5%" stop-color="#F60" />_x000D_
          <stop offset="95%" stop-color="#FF6" />_x000D_
        </linearGradient>_x000D_
      </defs>_x000D_
      _x000D_
      <rect width="100" height="50"/>_x000D_
    </svg>

If you split the filename on underscore and dot, you get an array of 3 strings. Join the first and third string, i.e. with index 0 and 2

$x = '237801_201011221155.xml' 
( $x.split('_.')[0] , $x.split('_.')[2] ) -join '.' 

Another way to do the same thing:

'237801_201011221155.xml'.split('_.')[0,2] -join '.'

After some time I will just copy all array elements (excluding these unwanted) to new array

The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:

Simple PHP mail script

Using a script like that, you'd POST the contents of your web form to the script, using a function like this:

jQuery.post

And then the script would take those values, plus a username and password for the mail server, and connect to the server to send the mail.

Verify current version of python by:

$ python --version

then check python is symbolic link to which file.

  $ ll /usr/bin/python

Output Ex:

 lrwxrwxrwx 1 root root 9 Jun 16  2014 /usr/bin/python -> python2.7*

Check other available versions of python:

$ ls /usr/bin/python*

Output Ex:

/usr/bin/python     /usr/bin/python2.7-config  /usr/bin/python3.4         /usr/bin/python3.4m-config  /usr/bin/python3.6m         /usr/bin/python3m
/usr/bin/python2    /usr/bin/python2-config    /usr/bin/python3.4-config  /usr/bin/python3.6          /usr/bin/python3.6m-config  /usr/bin/python3m-config
/usr/bin/python2.7  /usr/bin/python3           /usr/bin/python3.4m        /usr/bin/python3.6-config   /usr/bin/python3-config     /usr/bin/python-config

If want to change current version of python to 3.6 version edit file ~/.bashrc:

vim ~/.bashrc

add below line in the end of file and save:

alias python=/usr/local/bin/python3.6

To install pip for python 3.6

$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip

On Success, check current version of pip:

$ pip3 -V

Output Ex:

pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)

I had the same problem: The reason of "Received unregistered task of type.." was that celeryd service didn't find and register the tasks on service start (btw their list is visible when you start ./manage.py celeryd --loglevel=info ).

These tasks should be declared in CELERY_IMPORTS = ("tasks", ) in settings file.
If you have a special celery_settings.py file it has to be declared on celeryd service start as --settings=celery_settings.py as digivampire wrote.

This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.

The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);  

As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.

Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:

The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null. In other words, leaving the anchor null ensures the tip points where it is supposed to point.

However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.

By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.

var pinShadow = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
    null,
    null,
    /* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
    new google.maps.Point(40, 110), 
    new google.maps.Size(120, 110)); 

to give this:

This CAN be done with pure html and css. It may not be the best way but we all have different limitations. There are 3 ways that could be useful depending on what your specific circumstances are.

1. The first involves overlaying an invisible table over top of your link with a hover action on each cell that displays an image.

#imagehover td:hover::after{_x000D_
  content: "             ";_x000D_
  white-space: pre;_x000D_
  background-image: url("http://www.google.com/images/srpr/logo4w.png");_x000D_
  position: relative;_x000D_
  left: 5px;_x000D_
  top: 5px;_x000D_
  font-size: 20px;_x000D_
  background-color: transparent;_x000D_
  background-position: 0px 0px;_x000D_
  background-size: 60px 20px;_x000D_
  background-repeat: no-repeat;_x000D_
  _x000D_
}_x000D_
_x000D_
_x000D_
#imagehover table, #imagehover th, #imagehover td {_x000D_
  border: 0px;_x000D_
  border-spacing: 0px;_x000D_
}

<a href="https://www.google.com">_x000D_
<table id="imagehover" style="width:50px;height:10px;z-index:9999;position:absolute" cellspacing="0">_x000D_
<tr><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr>_x000D_

Google</a>

2. The second relies on being able to create your own cursor image

#googleLink{_x000D_
_x000D_
cursor: url(https://winter-bush-d06c.sto.workers.dev/cursor-extern.php?id=98272),url(https://9dc1a5c00e8109665645209c2d036b1c.cloudflareworkers.com/cursor-extern.php?id=98272),auto;_x000D_
_x000D_
}

<a href="https://www.google.com" id="googleLink">Google</a>

3. While the normal title tooltip doesn't technically allow images it does allow any unicode characters including block letters and emojis which may suite your needs.

<a href="https://www.google.com" title="??" alt="??">Google</a>

There is a string function (strtok) which can be used to split a string into smaller strings (tokens) based on some separator(s). For the purposes of this thread, the first word (defined as anything before the first space character) of Test me more can be obtained by tokenizing the string on the space character.

<?php
$value = "Test me more";
echo strtok($value, " "); // Test
?>

For more details and examples, see the strtok PHP manual page.

In those examples, no. If the statement is not the very last in the loop then they have very different effects.

This can also happen if you've been working on your scripts and functions and have been moving them around (i.e. changed the location of the definition) which could have accidentally created a looping reference.

You may find that the situation is solved if you just reset the iPython kernal to clear any old assignments:

%reset

or menu->restart terminal

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;

             String fromDateFormat = "dd/MM/yyyy";
             String fromdate = 15/03/2018; //Take any date

             String CheckFormat = "dd MMM yyyy";//take another format like dd/MMM/yyyy
             String dateStringFrom;

             Date DF = new Date();


              try

                 FromDF.setLenient(false);  // this is important!
                 Date FromDate = FromDF.parse(fromdate);

              {

                  System.out.println("Date error");

              }

output:- 15/03/2018

This is not a real answer, we have duplicate class

...but it works :)

class A {
    //do some things
}

class B {
    //do some things
}

class copy_B is copy all class B

class copy_B extends A {

    //do some things (copy class B)
}

class A_B extends copy_B{}

now

class C_A extends A{}
class C_B extends B{}
class C_A_b extends A_B{}  //extends A & B

You might want this (edit: allow number of the form 0123):

^\\+?[1-9]$|^\\+?\d+$

however, if it were me, I would instead do

int x = Integer.parseInt(s)
if (x > 0) {...}

While you cannot expose a new port of an existing container, you can start a new container in the same Docker network and get it to forward traffic to the original container.

# docker run \
  --rm \
  -p $PORT:1234 \
  verb/socat \
    TCP-LISTEN:1234,fork \
    TCP-CONNECT:$TARGET_CONTAINER_IP:$TARGET_CONTAINER_PORT

Worked Example

Launch a web-service that listens on port 80, but do not expose its internal port 80 (oops!):

# docker run -ti mkodockx/docker-pastebin   # Forgot to expose PORT 80!

Find its Docker network IP:

# docker inspect 63256f72142a | grep IPAddress
                    "IPAddress": "172.17.0.2",

Launch verb/socat with port 8080 exposed, and get it to forward TCP traffic to that IP's port 80:

# docker run --rm -p 8080:1234 verb/socat TCP-LISTEN:1234,fork TCP-CONNECT:172.17.0.2:80

You can now access pastebin on http://localhost:8080/, and your requests goes to socat:1234 which forwards it to pastebin:80, and the response travels the same path in reverse.

I found this;

Excel VBA ComboBox Lists

from here;

vba- Can a combobox present more then one column on it's textbox part?

and this may help;

Populating ComboBoxes VBA

I added a sort of demo here;

Playing with populating boxes.xlsm

The info at http://nelenkov.blogspot.com/2012/05/storing-application-secrets-in-androids.html is a fairly pragmatic, but "uses-hidden-android-apis" based approach. It's something to consider when you really can't get around storing credentials/passwords locally on the device.

I've also created a cleaned up gist of that idea at https://gist.github.com/kbsriram/5503519 which might be helpful.

Another way of initializing the array to a common value, would be to actually generate the list of elements in a series of defines:

#define DUP1( X ) ( X )
#define DUP2( X ) DUP1( X ), ( X )
#define DUP3( X ) DUP2( X ), ( X )
#define DUP4( X ) DUP3( X ), ( X )
#define DUP5( X ) DUP4( X ), ( X )
.
.
#define DUP100( X ) DUP99( X ), ( X )

#define DUPx( X, N ) DUP##N( X )
#define DUP( X, N ) DUPx( X, N )

Initializing an array to a common value can easily be done:

#define LIST_MAX 6
static unsigned char List[ LIST_MAX ]= { DUP( 123, LIST_MAX ) };

Note: DUPx introduced to enable macro substitution in parameters to DUP

To reduce verbosity, you can use a static import:

import static java.util.concurrent.TimeUnit.NANOSECONDS;

-and henceforth just type

NANOSECONDS.toSeconds(elapsedTime);

An alternative would be to use Font-Awesome for icons:

Including Font-Awesome

Open Font-Awesome on CDNJS and copy the CSS url of the latest version:

<link rel="stylesheet" href="<url>">

Or in CSS

@import url("<url>");

For example (note, the version will change):

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css">

Usage:

<i class="fa fa-bed"></i>

It contains a lot of icons!

Wouldn't it just be:

SELECT CURRENT_DATE - CHDLM FROM CHCART00 WHERE CHSTAT = '05';

That should return the number of days between the two dates, if I understand how date arithmetic works in DB2 correctly.

If CHDLM isn't a date you'll have to convert it to one. According to IBM the DATE() function would not be sufficient for the yyyymmdd format, but it would work if you can format like this: yyyy-mm-dd.

Say you have a superclass Fruit and the subclass Banana and you have a method addBananaToBasket()

The method will not accept grapes for example so you want to make sure that you're adding a banana to the basket.

So:

Fruit myFruit = new Banana();
((Banana)myFruit).addBananaToBasket(); ? This is called casting
