You seem to assign Double object into native double value field. Does that really compile?

Double.valueOf() creates a Double object so .doubleValue() should not be necessary.

If you want native double field, you need to define the field as double and then use .doubleValue()

After yum install python3-pip, check the name of the installed binary. e.g.

ll /usr/bin/pip*

On my CentOS 7, it is named as pip-3 instead of pip3.

Now this answer is for those lost souls that got here with this problem because they force-unmounted the drive but their hard drive is NTFS Formatted. Assuming you have ntfs-3g installed (sudo apt-get install ntfs-3g).

sudo ntfs-3g /dev/hdd /mnt/mount_point -o force

Where hdd is the hard drive in question and the "/mnt/mount_point" directory exists.

NOTES: This fixed the issue on an Ubuntu 18.04 machine using NTFS drives that had their journal files reset through sudo ntfsfix /dev/hdd and unmounted by force using sudo umount -l /mnt/mount_point

Leaving my answer here in case this fix can aid anyone!

Though it is perfectly possible to use a recursive regex as MizardX has posted, for this kind of things it is much more useful a parser. Regexes were originally intended to be used with regular languages, being recursive or having balancing groups is just a patch.

The language that defines valid regexes is actually a context free grammar, and you should use an appropriate parser for handling it. Here is an example for a university project for parsing simple regexes (without most constructs). It uses JavaCC. And yes, comments are in Spanish, though method names are pretty self-explanatory.

The correct way to 'solve' it is to close the connection and forget about the client. The client has closed the connection while you where still writing to it, so he doesn't want to know you, so that's it, isn't it?

I have solved this issue by storing images on internal storage and then using .setImageURI() rather than .setBitmap().

There are already great answers about the advantages of using list initialization, however my personal rule of thumb is NOT to use curly braces whenever possible, but instead make it dependent on the conceptual meaning:

• If the object I'm creating conceptually holds the values I'm passing in the constructor (e.g. containers, POD structs, atomics, smart pointers etc.), then I'm using the braces.
• If the constructor resembles a normal function call (it performs some more or less complex operations that are parametrized by the arguments) then I'm using the normal function call syntax.
• For default initialization I always use curly braces.
  For one, that way I'm always sure that the object gets initialized irrespective of whether it e.g. is a "real" class with a default constructor that would get called anyway or a builtin / POD type. Second it is - in most cases - consistent with the first rule, as a default initialized object often represents an "empty" object.

In my experience, this ruleset can be applied much more consistently than using curly braces by default, but having to explicitly remember all the exceptions when they can't be used or have a different meaning than the "normal" function-call syntax with parenthesis (calls a different overload).

It e.g. fits nicely with standard library-types like std::vector:

vector<int> a{10,20};   //Curly braces -> fills the vector with the arguments

vector<int> b(10,20);   //Parentheses -> uses arguments to parametrize some functionality,                          
vector<int> c(it1,it2); //like filling the vector with 10 integers or copying a range.

vector<int> d{};      //empty braces -> default constructs vector, which is equivalent
                      //to a vector that is filled with zero elements

tSql escapes a double quote with another double quote. So if you wanted it to be part of your sql string literal you would do this:

declare @xml xml 
set @xml = "<transaction><item value=""hi"" /></transaction>"

If you want to include a quote inside a value in the xml itself, you use an entity, which would look like this:

declare @xml xml
set @xml = "<transaction><item value=""hi &quot;mom&quot; lol"" /></transaction>"

You can run a command as admin using

sudo <command>

You can also switch to root and every command will be run as root

sudo su

You need to delete your old db folder and recreate new one. It will resolve your issue.

Here is a simple implementation that handles an unequal number of classes in the predicted and actual labels (see examples 3 and 4). I hope this helps!

For folks just learning this, here's a quick review. The labels for the columns indicate the predicted class, and the labels for the rows indicate the correct class. In example 1, we have [3 1] on the top row. Again, rows indicate truth, so this means that the correct label is "0" and there are 4 examples with ground truth label of "0". Columns indicate predictions, so we have 3/4 of the samples correctly labeled as "0", but 1/4 was incorrectly labeled as a "1".

def confusion_matrix(actual, predicted):
    classes       = np.unique(np.concatenate((actual,predicted)))
    confusion_mtx = np.empty((len(classes),len(classes)),dtype=np.int)
    for i,a in enumerate(classes):
        for j,p in enumerate(classes):
            confusion_mtx[i,j] = np.where((actual==a)*(predicted==p))[0].shape[0]
    return confusion_mtx

Example 1:

actual    = np.array([1,1,1,1,0,0,0,0])
predicted = np.array([1,1,1,1,0,0,0,1])
confusion_matrix(actual,predicted)

   0  1
0  3  1
1  0  4

Example 2:

actual    = np.array(["a","a","a","a","b","b","b","b"])
predicted = np.array(["a","a","a","a","b","b","b","a"])
confusion_matrix(actual,predicted)

   0  1
0  4  0
1  1  3

Example 3:

actual    = np.array(["a","a","a","a","b","b","b","b"])
predicted = np.array(["a","a","a","a","b","b","b","z"]) # <-- notice the 3rd class, "z"
confusion_matrix(actual,predicted)

   0  1  2
0  4  0  0
1  0  3  1
2  0  0  0

Example 4:

actual    = np.array(["a","a","a","x","x","b","b","b"]) # <-- notice the 4th class, "x"
predicted = np.array(["a","a","a","a","b","b","b","z"])
confusion_matrix(actual,predicted)

   0  1  2  3
0  3  0  0  0
1  0  2  0  1
2  1  1  0  0
3  0  0  0  0

If replacement is of different length:

1. Read file until you find the string you want to replace.
2. Read into memory the part after text you want to replace, all of it.
3. Truncate the file at start of the part you want to replace.
4. Write replacement.
5. Write rest of the file from step 2.

If replacement is of same length:

1. Read file until you find the string you want to replace.
2. Set file position to start of the part you want to replace.
3. Write replacement, overwriting part of file.

This is the best you can get, with constraints of your question. However, at least the example in question is replacing string of same length, So the second way should work.

Also be aware: Java strings are Unicode text, while text files are bytes with some encoding. If encoding is UTF8, and your text is not Latin1 (or plain 7-bit ASCII), you have to check length of encoded byte array, not length of Java string.

Limited disk space can cause to this error.

Check your disk space

$ df -h

Try to increase the space if there are 100% used disks.

In my case: I have Vagrant (8.0.1) box (Ubuntu 16.04) My mysql disk capacity was 10GB, I increased it to 20GB

$ sudo lvextend -L20G -r /dev/mapper/homestead--vg-mysql--master

Then restart mysql

Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.

In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:

CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
  one int;
  two int;
BEGIN
  one := 1;
  two := 2;
  RETURN one + two;
END
$$;
SELECT somefuncname();

The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.

If you don't want to use any click event then you can set timer for periodically update.

Below code may be help you just example.

function update() {
  $.get("response.php", function(data) {
    $("#some_div").html(data);
    window.setTimeout(update, 10000);
  });
}

Above function will call after every 10 seconds and get content from response.php and update in #some_div.

I received this error when I imported Module A into Module B, and then tried to use a component from Module A in Module B.

The solution is to declare that component in the exports array.

@NgModule({
  declarations: [
    MyComponent
  ],
  exports: [
    MyComponent
  ]
})
export class ModuleA {}

@NgModule({
  imports: [
    ModuleA
  ]
})
export class ModuleB {}

After adding the user to the vboxsf group, you might need to completely log out of the gnome/xfce/??? session, because someone long ago decided that group affiliation should be cached at first login to the window system.

Or go old school:

% newgrp vboxsf

in any shell you want to use to access the folder. Luckily, newgrp looks up the group list for itself and doesn't used the cached values. You'll still need to log out and back in to access the folder from something other than a shell.

Something like this should do:

function cleanLocalStorage() {
    for(key in localStorage) {
        delete localStorage[key];
    }
}

Be careful about using this, though, as the user may have other data stored in localStorage and would probably be pretty ticked if you deleted that. I'd recommend either a) not storing the user's data in localStorage or b) storing the user's account stuff in a single variable, and then clearing that instead of deleting all the keys in localStorage.

Edit: As Lyn pointed out, you'll be good with localStorage.clear(). My previous points still stand, however.

I have developed the algorithm to work with heterogeneous OS, both Windows and Linux.

Implement the following class:

<?php

    class CheckDevice {

        public function myOS(){
            if (strtoupper(substr(PHP_OS, 0, 3)) === (chr(87).chr(73).chr(78)))
                return true;

            return false;
        }

        public function ping($ip_addr){
            if ($this->myOS()){
                if (!exec("ping -n 1 -w 1 ".$ip_addr." 2>NUL > NUL && (echo 0) || (echo 1)"))
                    return true;
            } else {
                if (!exec("ping -q -c1 ".$ip_addr." >/dev/null 2>&1 ; echo $?"))
                    return true;
            }

            return false;
        }
    }

    $ip_addr = "151.101.193.69"; #DNS: www.stackoverflow.com

    if ((new CheckDevice())->ping($ip_addr))
        echo "The device exists";
    else 
        echo "The device is not connected";

There are quite a few ways to get the result you are after. Lets break them in categories:

ES6 Values only:

Main method for this is Object.values. But using Object.keys and Array.map you could as well get to the expected result:

Object.values(obj)
Object.keys(obj).map(k => obj[k])

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('Object.values:', Object.values(obj))_x000D_
console.log('Object.keys:', Object.keys(obj).map(k => obj[k]))

ES6 Key & Value:

Using map and ES6 dynamic/computed properties and destructuring you can retain the key and return an object from the map.

Object.keys(obj).map(k => ({[k]: obj[k]}))
Object.entries(obj).map(([k,v]) => ({[k]:v}))

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('Object.keys:', Object.keys(obj).map(k => ({_x000D_
  [k]: obj[k]_x000D_
})))_x000D_
console.log('Object.entries:', Object.entries(obj).map(([k, v]) => ({_x000D_
  [k]: v_x000D_
})))

Lodash Values only:

The method designed for this is _.values however there are "shortcuts" like _.map and the utility method _.toArray which would also return an array containing only the values from the object. You could also _.map though the _.keys and get the values from the object by using the obj[key] notation.

Note: _.map when passed an object would use its baseMap handler which is basically forEach on the object properties.

_.values(obj)
_.map(obj)
_.toArray(obj)
_.map(_.keys(obj), k => obj[k])

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('values:', _.values(obj))_x000D_
console.log('map:', _.map(obj))_x000D_
console.log('toArray:', _.toArray(obj))_x000D_
console.log('keys:', _.map(_.keys(obj), k => obj[k]))

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>

Lodash Key & Value:

// Outputs an array with [[KEY, VALUE]]
_.entries(obj)
_.toPairs(obj)

// Outputs array with objects containing the keys and values
_.map(_.entries(obj), ([k,v]) => ({[k]:v}))
_.map(_.keys(obj), k => ({[k]: obj[k]}))
_.transform(obj, (r,c,k) => r.push({[k]:c}), [])
_.reduce(obj, (r,c,k) => (r.push({[k]:c}), r), [])

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
// Outputs an array with [KEY, VALUE]_x000D_
console.log('entries:', _.entries(obj))_x000D_
console.log('toPairs:', _.toPairs(obj))_x000D_
_x000D_
// Outputs array with objects containing the keys and values_x000D_
console.log('entries:', _.map(_.entries(obj), ([k, v]) => ({_x000D_
  [k]: v_x000D_
})))_x000D_
console.log('keys:', _.map(_.keys(obj), k => ({_x000D_
  [k]: obj[k]_x000D_
})))_x000D_
console.log('transform:', _.transform(obj, (r, c, k) => r.push({_x000D_
  [k]: c_x000D_
}), []))_x000D_
console.log('reduce:', _.reduce(obj, (r, c, k) => (r.push({_x000D_
  [k]: c_x000D_
}), r), []))

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>

Note that in the above examples ES6 is used (arrow functions and dynamic properties). You can use lodash _.fromPairs and other methods to compose an object if ES6 is an issue.

This can happen when the cordova was installed globally on a different version of the node.

Being necessary to manually delete yourself as suggested in the previous comment:

which cordova

it will output something like this

/usr/local/bin/

then removing by

rm -rf /usr/local/bin/cordova

Because you say

struct arg_struct *args = (struct arg_struct *)args;

instead of

struct arg_struct *args = arguments;

There are various way to share data between activities

1: Passing data between activities using Intent

Intent intent=new Intent(this, desirableActivity.class);
intent.putExtra("KEY", "Value");
startActivity(intent)

2: Using static keyword , define variable as public static and use any where in project

      public static int sInitialValue=0;

use anywhere in project using classname.variableName;

3: Using Database

but its bit lengthy process, you have to use query for inserting data and iterate data using cursor when need. But there are no chance of losing data without cleaning cache.

4: Using shared Preferences

much easier than database. but there is some limitation you can not save ArrayList ,List and custome objects.

5: Create getter setter in Aplication class and access any where in project.

      private String data;
      public String getData() {
          return data;
      }

      public void setData(String data) {
          this.data = data;
      }

here set and get from activities

         ((YourApplicationClass)getApplicationContext()).setData("abc"); 

         String data=((YourApplicationClass)getApplicationContext()).getData();  

To get this in excel or csv format- right click the folder and select "copy response"- paste to excel and use text to columns.

Branches in SVN are essentially directories; you don't name the branch so much as choose the name of the directory to branch into.

The common way of 'naming' a branch is to place it under a directory called branches in your repository. In the "To URL:" portion of TortoiseSVN's Branch dialog, you would therefore enter something like:

(svn/http)://path-to-repo/branches/your-branch-name

The main branch of a project is referred to as the trunk, and is usually located in:

(svn/http)://path-to-repo/trunk

Mockito matchers are static methods and calls to those methods, which stand in for arguments during calls to when and verify.

Hamcrest matchers (archived version) (or Hamcrest-style matchers) are stateless, general-purpose object instances that implement Matcher<T> and expose a method matches(T) that returns true if the object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.

/* Mockito */  verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));

Mockito matchers exist, separate from Hamcrest-style matchers, so that descriptions of matching expressions fit directly into method invocations: Mockito matchers return T where Hamcrest matcher methods return Matcher objects (of type Matcher<T>).

Mockito matchers are invoked through static methods such as eq, any, gt, and startsWith on org.mockito.Matchers and org.mockito.AdditionalMatchers. There are also adapters, which have changed across Mockito versions:

• For Mockito 1.x, Matchers featured some calls (such as intThat or argThat) are Mockito matchers that directly accept Hamcrest matchers as parameters. ArgumentMatcher<T> extended org.hamcrest.Matcher<T>, which was used in the internal Hamcrest representation and was a Hamcrest matcher base class instead of any sort of Mockito matcher.
• For Mockito 2.0+, Mockito no longer has a direct dependency on Hamcrest. Matchers calls phrased as intThat or argThat wrap ArgumentMatcher<T> objects that no longer implement org.hamcrest.Matcher<T> but are used in similar ways. Hamcrest adapters such as argThat and intThat are still available, but have moved to MockitoHamcrest instead.

Regardless of whether the matchers are Hamcrest or simply Hamcrest-style, they can be adapted like so:

/* Mockito matcher intThat adapting Hamcrest-style matcher is(greaterThan(...)) */
verify(foo).setPowerLevel(intThat(is(greaterThan(9000))));

In the above statement: foo.setPowerLevel is a method that accepts an int. is(greaterThan(9000)) returns a Matcher<Integer>, which wouldn't work as a setPowerLevel argument. The Mockito matcher intThat wraps that Hamcrest-style Matcher and returns an int so it can appear as an argument; Mockito matchers like gt(9000) would wrap that entire expression into a single call, as in the first line of example code.

What matchers do/return

when(foo.quux(3, 5)).thenReturn(true);

When not using argument matchers, Mockito records your argument values and compares them with their equals methods.

when(foo.quux(eq(3), eq(5))).thenReturn(true);    // same as above
when(foo.quux(anyInt(), gt(5))).thenReturn(true); // this one's different

When you call a matcher like any or gt (greater than), Mockito stores a matcher object that causes Mockito to skip that equality check and apply your match of choice. In the case of argumentCaptor.capture() it stores a matcher that saves its argument instead for later inspection.

Matchers return dummy values such as zero, empty collections, or null. Mockito tries to return a safe, appropriate dummy value, like 0 for anyInt() or any(Integer.class) or an empty List<String> for anyListOf(String.class). Because of type erasure, though, Mockito lacks type information to return any value but null for any() or argThat(...), which can cause a NullPointerException if trying to "auto-unbox" a null primitive value.

Matchers like eq and gt take parameter values; ideally, these values should be computed before the stubbing/verification starts. Calling a mock in the middle of mocking another call can interfere with stubbing.

Matcher methods can't be used as return values; there is no way to phrase thenReturn(anyInt()) or thenReturn(any(Foo.class)) in Mockito, for instance. Mockito needs to know exactly which instance to return in stubbing calls, and will not choose an arbitrary return value for you.

Implementation details

Matchers are stored (as Hamcrest-style object matchers) in a stack contained in a class called ArgumentMatcherStorage. MockitoCore and Matchers each own a ThreadSafeMockingProgress instance, which statically contains a ThreadLocal holding MockingProgress instances. It's this MockingProgressImpl that holds a concrete ArgumentMatcherStorageImpl. Consequently, mock and matcher state is static but thread-scoped consistently between the Mockito and Matchers classes.

Most matcher calls only add to this stack, with an exception for matchers like and, or, and not. This perfectly corresponds to (and relies on) the evaluation order of Java, which evaluates arguments left-to-right before invoking a method:

when(foo.quux(anyInt(), and(gt(10), lt(20)))).thenReturn(true);
[6]      [5]  [1]       [4] [2]     [3]

This will:

1. Add anyInt() to the stack.
2. Add gt(10) to the stack.
3. Add lt(20) to the stack.
4. Remove gt(10) and lt(20) and add and(gt(10), lt(20)).
5. Call foo.quux(0, 0), which (unless otherwise stubbed) returns the default value false. Internally Mockito marks quux(int, int) as the most recent call.
6. Call when(false), which discards its argument and prepares to stub method quux(int, int) identified in 5. The only two valid states are with stack length 0 (equality) or 2 (matchers), and there are two matchers on the stack (steps 1 and 4), so Mockito stubs the method with an any() matcher for its first argument and and(gt(10), lt(20)) for its second argument and clears the stack.

This demonstrates a few rules:

• Mockito can't tell the difference between quux(anyInt(), 0) and quux(0, anyInt()). They both look like a call to quux(0, 0) with one int matcher on the stack. Consequently, if you use one matcher, you have to match all arguments.

• Call order isn't just important, it's what makes this all work. Extracting matchers to variables generally doesn't work, because it usually changes the call order. Extracting matchers to methods, however, works great.

  int between10And20 = and(gt(10), lt(20));
  /* BAD */ when(foo.quux(anyInt(), between10And20)).thenReturn(true);
  // Mockito sees the stack as the opposite: and(gt(10), lt(20)), anyInt().
  
  public static int anyIntBetween10And20() { return and(gt(10), lt(20)); }
  /* OK */  when(foo.quux(anyInt(), anyIntBetween10And20())).thenReturn(true);
  // The helper method calls the matcher methods in the right order.
  

• The stack changes often enough that Mockito can't police it very carefully. It can only check the stack when you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when or verify, but Mockito can't check that automatically. You can check manually with Mockito.validateMockitoUsage().

• In a call to when, Mockito actually calls the method in question, which will throw an exception if you've stubbed the method to throw an exception (or require non-zero or non-null values). doReturn and doAnswer (etc) do not invoke the actual method and are often a useful alternative.

• If you had called a mock method in the middle of stubbing (e.g. to calculate an answer for an eq matcher), Mockito would check the stack length against that call instead, and likely fail.

• If you try to do something bad, like stubbing/verifying a final method, Mockito will call the real method and also leave extra matchers on the stack. The final method call may not throw an exception, but you may get an InvalidUseOfMatchersException from the stray matchers when you next interact with a mock.

Common problems

• InvalidUseOfMatchersException:

  • Check that every single argument has exactly one matcher call, if you use matchers at all, and that you haven't used a matcher outside of a when or verify call. Matchers should never be used as stubbed return values or fields/variables.

  • Check that you're not calling a mock as a part of providing a matcher argument.

  • Check that you're not trying to stub/verify a final method with a matcher. It's a great way to leave a matcher on the stack, and unless your final method throws an exception, this might be the only time you realize the method you're mocking is final.

• NullPointerException with primitive arguments: (Integer) any() returns null while any(Integer.class) returns 0; this can cause a NullPointerException if you're expecting an int instead of an Integer. In any case, prefer anyInt(), which will return zero and also skip the auto-boxing step.

• NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz) will actually call foo.bar(null), which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any()) skips the stubbed behavior.

General troubleshooting

• Use MockitoJUnitRunner, or explicitly call validateMockitoUsage in your tearDown or @After method (which the runner would do for you automatically). This will help determine whether you've misused matchers.

• For debugging purposes, add calls to validateMockitoUsage in your code directly. This will throw if you have anything on the stack, which is a good warning of a bad symptom.

I solved this problem by adding appcompatv7 library to my project, though I don't require this library(as I my project don't target lower versions) I don't know why I had to add this. Hope someone else can solve their problem by adding same.

As of matplotlib v1.4.0rc4, a remove method has been added to the legend object.

Usage:

ax.get_legend().remove()

or

legend = ax.legend(...)
...
legend.remove()

See here for the commit where this was introduced.

There are a few ways to do this, as mentioned above, but in my experience the best way to manipulate an XHR request and resend is to use chrome dev tools to copy the request as cURL request (right click on the request in the network tab) and to simply import into the Postman app (giant import button in the top left).

Be extremely careful using any of the other suggestions. It all depends on context.

I have spent a long time tracing a bugs in a system that presumed a==b if |a-b|<epsilon. The underlying problems were:

1. The implicit presumption in an algorithm that if a==b and b==c then a==c.

2. Using the same epsilon for lines measured in inches and lines measured in mils (.001 inch). That is a==b but 1000a!=1000b. (This is why AlmostEqual2sComplement asks for the epsilon or max ULPS).

3. The use of the same epsilon for both the cosine of angles and the length of lines!

4. Using such a compare function to sort items in a collection. (In this case using the builtin C++ operator == for doubles produced correct results.)

Like I said: it all depends on context and the expected size of a and b.

BTW, std::numeric_limits<double>::epsilon() is the "machine epsilon". It is the difference between 1.0 and the next value representable by a double. I guess that it could be used in the compare function but only if the expected values are less than 1. (This is in response to @cdv's answer...)

Also, if you basically have int arithmetic in doubles (here we use doubles to hold int values in certain cases) your arithmetic will be correct. For example 4.0/2.0 will be the same as 1.0+1.0. This is as long as you do not do things that result in fractions (4.0/3.0) or do not go outside of the size of an int.

You need not store the diff in a 3rd file and then read from in. Instead you make use of the Runtime.exec

Process p = Runtime.getRuntime().exec("diff fileA fileB");
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
while ((s = stdInput.readLine()) != null) {
        System.out.println(s);
}

In addition to @senderle's here, some might also be wondering how to use the functionality of multiprocessing.Pool.

The nice thing is that there is a .Pool() method to the manager instance that mimics all the familiar API of the top-level multiprocessing.

from itertools import repeat
import multiprocessing as mp
import os
import pprint

def f(d: dict) -> None:
    pid = os.getpid()
    d[pid] = "Hi, I was written by process %d" % pid

if __name__ == '__main__':
    with mp.Manager() as manager:
        d = manager.dict()
        with manager.Pool() as pool:
            pool.map(f, repeat(d, 10))
        # `d` is a DictProxy object that can be converted to dict
        pprint.pprint(dict(d))

Output:

$ python3 mul.py 
{22562: 'Hi, I was written by process 22562',
 22563: 'Hi, I was written by process 22563',
 22564: 'Hi, I was written by process 22564',
 22565: 'Hi, I was written by process 22565',
 22566: 'Hi, I was written by process 22566',
 22567: 'Hi, I was written by process 22567',
 22568: 'Hi, I was written by process 22568',
 22569: 'Hi, I was written by process 22569',
 22570: 'Hi, I was written by process 22570',
 22571: 'Hi, I was written by process 22571'}

This is a slightly different example where each process just logs its process ID to the global DictProxy object d.

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

I second Dipaks' answer, but often just the text-indent is enough as you may/maynot be positioning the ul for better layout control.

ul li{
text-indent: -1em;
}

Try

   <td style="word-wrap: break-word">Long text here</td>

I found this answer on a Google forum that has worked me. In the footnotes it mentions 'googleapps.exe' - I don't have this and it has still worked. Simply follow the instructions below but close down all applications before making changes to the Registry. Also I saved the existing value just in case it didn't work.

Simply type "run" in your search bar, then type "regedit" then travel to:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\mailto\shell\open\command\ 

edit (double click) "(Default)" to:

"C:\Program Files (x86)\Google\Google Apps\googleapps.exe" --domain= --mailto.google.com="%1" 

That's it! Save and close it and it should work beautifully!

Using this method prevents you from having to download the GMail Notifier, which for those of us with GTalk don't need since it does it for us. I'm not sure why Google can't solve this issue easily.. i've heard Google Apps haven't been tested fully on Windows 7 but it's obvious the same tag works with it.

Note: The only thing with this solution is you need to have the googleapps.exe file on your machine. I believe I got it with my free GooglePack from their site which has now been discontinued. I tried searching the net for a way to download it but weirdly enough it seems it's reserved only for Businesses now and there is no download link available from the web because everyone who has it streamed it using the google updater.. Odd. Anyway good luck!

There is a hashchange plug-in which wraps up the functionality and cross browser issues available here.

you can use just javascript for it

var total =10.8
(total).toFixed(2); 10.80


alert(total.toFixed(2))); 

You'll need to use os.stat to get the file creation time and a combination of time.strftime and time.timezone for formatting:

>>> import time
>>> import os
>>> t = os.stat('C:/Path/To/File.txt').st_ctime
>>> t = time.localtime(t)
>>> formatted = time.strftime('%Y-%m-%d %H:%M:%S', t)
>>> tz = str.format('{0:+06.2f}', float(time.timezone) / 3600)
>>> final = formatted + tz
>>> 
>>> final
'2008-11-24 14:46:08-02.00'

try adding this in AppDelegate applicationWillEnterForeground.

func applicationWillEnterForeground(_ application: UIApplication) {        
    // makes viewWillAppear run
    self.window?.rootViewController?.beginAppearanceTransition(true, animated: false)
    self.window?.rootViewController?.endAppearanceTransition()
}

I'm maintaining a GUI and CLI based service that allows you to generate .gitignore templates very easily at https://www.gitignore.io.

You can either type the templates you want in the search field or install the command line alias and run

I found this helpful for my conversion, without string manipulation. https://docs.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql

CONVERT(VARCHAR(23), @lastUploadEndDate, 121)

yyyy-mm-dd hh:mi:ss.mmm(24h) was the format I needed.

For Java, from a command line:

java -version

will indicate whether it's 64-bit or not.

Output from the console on my Ubuntu box:

java version "1.6.0_12-ea"
Java(TM) SE Runtime Environment (build 1.6.0_12-ea-b03)
Java HotSpot(TM) 64-Bit Server VM (build 11.2-b01, mixed mode)

IE will indicate 64-bit versions in the About dialog, I believe.

According to Bryan's response you can do this to limit decimals in a query. I convert from km/h to m/s and display it in dygraphs but when I did it in dygraphs it looked weird. Looks fine when doing the calculation in the query instead. This is on postgresql 9.5.1.

select date,(wind_speed/3.6)::numeric(7,1) from readings;

You can reset the padding (and I think everything else) with initial to the default.

p {
    padding: initial;
}

You could also try setting style inline without using a variable, like so:

style={{"height" : "100%"}} or,

for multiple attributes: style={{"height" : "100%", "width" : "50%"}}

RUN git clone http://username:password@url/example.git
WORKDIR /folder
RUN make

With no parameters, the .hide() method is the simplest way to hide an element:

$('.target').hide(); The matched elements will be hidden immediately, with no animation. This is roughly equivalent to calling .css('display', 'none'), except that the value of the display property is saved in jQuery's data cache so that display can later be restored to its initial value. If an element has a display value of inline, then is hidden and shown, it will once again be displayed inline.

Same about show

I found a simple way to fix that problem. At binding datagridview you've just done: datagridview.DataSource = dataSetName.Tables["TableName"];

If you code like:

datagridview.DataSource = dataSetName;
datagridview.DataMember = "TableName";

the datagridview will never load data again when filtering.

Seems the easiest method is simply to use the Replace method that ships with .Net and has been around since .Net 1.0:

string res = Microsoft.VisualBasic.Strings.Replace(res, 
                                   "%PolicyAmount%", 
                                   "$0", 
                                   Compare: Microsoft.VisualBasic.CompareMethod.Text);

In order to use this method, you have to add a Reference to the Microsoft.VisualBasic assemblly. This assembly is a standard part of the .Net runtime, it is not an extra download or marked as obsolete.

Can't comment on Susam Pal's answer but if you're dealing with spaces, I'd surround with quotes:

for f in *.jpg; do mv "$f" "`echo $f | sed s/\ /\-/g`"; done;

Assuming an interactive shell, and you'd like to keep your current command history and also load /etc/profile (which loads environment data including /etc/bashrc and on Mac OS X loads paths defined in /etc/paths.d/ via path_helper), append your command history and do an exec of bash with the login ('-l') option:

history -a && exec bash -l

Check out the sample code. It help you.

 private ProgressBar progressBar;
 progressBar=(ProgressBar)findViewById(R.id.webloadProgressBar);
 WebView urlWebView= new WebView(Context);
    urlWebView.setWebViewClient(new AppWebViewClients(progressBar));
                        urlWebView.getSettings().setJavaScriptEnabled(true);
                        urlWebView.loadUrl(detailView.getUrl());

public class AppWebViewClients extends WebViewClient {
     private ProgressBar progressBar;

    public AppWebViewClients(ProgressBar progressBar) {
        this.progressBar=progressBar;
        progressBar.setVisibility(View.VISIBLE);
    }
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // TODO Auto-generated method stub
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        // TODO Auto-generated method stub
        super.onPageFinished(view, url);
        progressBar.setVisibility(View.GONE);
    }
}

Thanks.

Process Explorer can show total CPU time taken by a process, as well as a history graph per process.

You can remove the warning by adding the below code in <intent-filter> inside <activity>

<action android:name="android.intent.action.VIEW" />

$string = "picture_0007_value";
$findChar =strrpos($string,"_");
if($findChar !== FALSE) {
  $string[$findChar]=".";
}

echo $string;

Apart from the mistakes in the code, Faruk Unal has the best anwser. One function does the trick.

Completely untested, but this should work:

View positiveButton = findViewById(R.id.positiveButton);
RelativeLayout.LayoutParams layoutParams = 
    (RelativeLayout.LayoutParams)positiveButton.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
positiveButton.setLayoutParams(layoutParams);

add android:configChanges="orientation|screenSize" inside your activity in your manifest

mp3 files sometimes throw strange mime types as per this answer: https://stackoverflow.com/a/2755288/14482130

If you are doing some user validation do not allow 'application/octet-stream' or 'application/x-zip-compressed' as suggested above since they can contain be .exe or other potentially dangerous files.

In order to validate when mime type gives a false negative you can use fleep as per this answer https://stackoverflow.com/a/52570299/14482130 to finish the validation.

I find the existing answers a little confusing, because they only indirectly indicate the essential mystifying thing in the code example: both* the "print i" and the "next(a)" are causing their results to be printed.

Since they're printing alternating elements of the original sequence, and it's unexpected that the "next(a)" statement is printing, it appears as if the "print i" statement is printing all the values.

In that light, it becomes more clear that assigning the result of "next(a)" to a variable inhibits the printing of its' result, so that just the alternate values that the "i" loop variable are printed. Similarly, making the "print" statement emit something more distinctive disambiguates it, as well.

(One of the existing answers refutes the others because that answer is having the example code evaluated as a block, so that the interpreter is not reporting the intermediate values for "next(a)".)

The beguiling thing in answering questions, in general, is being explicit about what is obvious once you know the answer. It can be elusive. Likewise critiquing answers once you understand them. It's interesting...

In javascript the "+" operator is used to add numbers or to concatenate strings. if one of the operands is a string "+" concatenates, and if it is only numbers it adds them.

example:

1+2+3 == 6
"1"+2+3 == "123"

I'll give you one nice function for this problem:

function url_redirect(url){
    var X = setTimeout(function(){
        window.location.replace(url);
        return true;
    },300);

    if( window.location = url ){
        clearTimeout(X);
        return true;
    } else {
        if( window.location.href = url ){
            clearTimeout(X);
            return true;
        }else{
            clearTimeout(X);
            window.location.replace(url);
            return true;
        }
    }
    return false;
};

This is universal working solution for the window.location problem. Some browsers go into problem with window.location.href and also sometimes can happen that window.location fail. That's why we also use window.location.replace() for any case and timeout for the "last try".

The format shortcut in C# didn't work for me until I installed Mono for Mac OS X, DNVM and DNX.

Before I installed Mono, the auto-format shortcut (Shift + Alt + F) worked only for the .json files.

Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:

label1.txt = "Pizza" 
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();

If I already know its a Pizza there's no advantage to:

p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();

but I see a huge advantage to the Magic method if it exists.

It's very important to point out that view.layoutIfNeeded() applies to the view subviews only.

Therefore to animate the view constraint, it is important to call it on the view-to-animate superview as follows:

    topConstraint.constant = heightShift

    UIView.animate(withDuration: 0.3) {

        // request layout on the *superview*
        self.view.superview?.layoutIfNeeded()
    }

An example for a simple layout as follows:

class MyClass {

    /// Container view
    let container = UIView()
        /// View attached to container
        let view = UIView()

    /// Top constraint to animate
    var topConstraint = NSLayoutConstraint()


    /// Create the UI hierarchy and constraints
    func createUI() {
        container.addSubview(view)

        // Create the top constraint
        topConstraint = view.topAnchor.constraint(equalTo: container.topAnchor, constant: 0)


        view.translatesAutoresizingMaskIntoConstraints = false

        // Activate constaint(s)
        NSLayoutConstraint.activate([
           topConstraint,
        ])
    }

    /// Update view constraint with animation
    func updateConstraint(heightShift: CGFloat) {
        topConstraint.constant = heightShift

        UIView.animate(withDuration: 0.3) {

            // request layout on the *superview*
            self.view.superview?.layoutIfNeeded()
        }
    }
}

The most straight forward solution to determine the rank of a given value is to count the number of values before it. Suppose we have the following values:

10 20 30 30 30 40

• All 30 values are considered 3rd
• All 40 values are considered 6th (rank) or 4th (dense rank)

Now back to the original question. Here is some sample data which is sorted as described in OP (expected ranks are added on the right):

+------+-----------+------+--------+    +------+------------+
| id   | firstname | age  | gender |    | rank | dense_rank |
+------+-----------+------+--------+    +------+------------+
|   11 | Emily     |   20 | F      |    |    1 |          1 |
|    3 | Grace     |   25 | F      |    |    2 |          2 |
|   20 | Jill      |   25 | F      |    |    2 |          2 |
|   10 | Megan     |   26 | F      |    |    4 |          3 |
|    8 | Lucy      |   27 | F      |    |    5 |          4 |
|    6 | Sarah     |   30 | F      |    |    6 |          5 |
|    9 | Zoe       |   30 | F      |    |    6 |          5 |
|   14 | Kate      |   35 | F      |    |    8 |          6 |
|    4 | Harry     |   20 | M      |    |    1 |          1 |
|   12 | Peter     |   20 | M      |    |    1 |          1 |
|   13 | John      |   21 | M      |    |    3 |          2 |
|   16 | Cole      |   25 | M      |    |    4 |          3 |
|   17 | Dennis    |   27 | M      |    |    5 |          4 |
|    5 | Scott     |   30 | M      |    |    6 |          5 |
|    7 | Tony      |   30 | M      |    |    6 |          5 |
|    2 | Matt      |   31 | M      |    |    8 |          6 |
|   15 | James     |   32 | M      |    |    9 |          7 |
|    1 | Adams     |   33 | M      |    |   10 |          8 |
|   18 | Smith     |   35 | M      |    |   11 |          9 |
|   19 | Zack      |   35 | M      |    |   11 |          9 |
+------+-----------+------+--------+    +------+------------+

To calculate RANK() OVER (PARTITION BY Gender ORDER BY Age) for Sarah, you can use this query:

SELECT COUNT(id) + 1 AS rank, COUNT(DISTINCT age) + 1 AS dense_rank
FROM testdata
WHERE gender = (SELECT gender FROM testdata WHERE id = 6)
AND age < (SELECT age FROM testdata WHERE id = 6)

+------+------------+
| rank | dense_rank |
+------+------------+
|    6 |          5 |
+------+------------+

To calculate RANK() OVER (PARTITION BY Gender ORDER BY Age) for All rows you can use this query:

SELECT testdata.id, COUNT(lesser.id) + 1 AS rank, COUNT(DISTINCT lesser.age) + 1 AS dense_rank
FROM testdata
LEFT JOIN testdata AS lesser ON lesser.age < testdata.age AND lesser.gender = testdata.gender
GROUP BY testdata.id

And here is the result (joined values are added on right):

+------+------+------------+    +-----------+-----+--------+

A good place to look at is the man page of bash. Here's an online version. Look for "INVOCATION" section.

You can try:

SELECT id FROM your_table WHERE id = (SELECT MAX(id) FROM your_table)

Where id is a primary key of the your_table

For people who would have similar problems in the future, beware that this problem is fundamentally rooted in the mismatch of your iOS version and Xcode version.

Check the compatibility of iOS and Xcode.

This error also occurs if you have a block with no statements in it

For example:

def my_function():
    for i in range(1,10):


def say_hello():
    return "hello"

Notice that the for block is empty. You can use the pass statement if you want to test the remaining code in the module.

Just add two lines in your php.ini file.

extension=php_openssl.dll

allow_url_include = On

its working for me.

I'm reading my text from a file, so I took a slightly different approach, since adding \n to the file resulted in \n appearing in the text.

    final TextView textView = (TextView) findViewById(R.id.warm_up_view);
    StringBuilder sb = new StringBuilder();
    Scanner scanner = new Scanner(getResources().openRawResource(R.raw.warm_up_file));
    while (scanner.hasNextLine()) {
      sb.append(scanner.nextLine());
      sb.append("\n");
    }

    textView.setText(sb.toString());

FYI, the on_delete parameter in models is backwards from what it sounds like. You put on_delete on a foreign key (FK) on a model to tell Django what to do if the FK entry that you are pointing to on your record is deleted. The options our shop have used the most are PROTECT, CASCADE, and SET_NULL. Here are the basic rules I have figured out:

1. Use PROTECT when your FK is pointing to a look-up table that really shouldn't be changing and that certainly should not cause your table to change. If anyone tries to delete an entry on that look-up table, PROTECT prevents them from deleting it if it is tied to any records. It also prevents Django from deleting your record just because it deleted an entry on a look-up table. This last part is critical. If someone were to delete the gender "Female" from my Gender table, I CERTAINLY would NOT want that to instantly delete any and all people I had in my Person table who had that gender.
2. Use CASCADE when your FK is pointing to a "parent" record. So, if a Person can have many PersonEthnicity entries (he/she can be American Indian, Black, and White), and that Person is deleted, I really would want any "child" PersonEthnicity entries to be deleted. They are irrelevant without the Person.
3. Use SET_NULL when you do want people to be allowed to delete an entry on a look-up table, but you still want to preserve your record. For example, if a Person can have a HighSchool, but it doesn't really matter to me if that high-school goes away on my look-up table, I would say on_delete=SET_NULL. This would leave my Person record out there; it just would just set the high-school FK on my Person to null. Obviously, you will have to allow null=True on that FK.

Here is an example of a model that does all three things:

class PurchPurchaseAccount(models.Model):
    id = models.AutoField(primary_key=True)
    purchase = models.ForeignKey(PurchPurchase, null=True, db_column='purchase', blank=True, on_delete=models.CASCADE) # If "parent" rec gone, delete "child" rec!!!
    paid_from_acct = models.ForeignKey(PurchPaidFromAcct, null=True, db_column='paid_from_acct', blank=True, on_delete=models.PROTECT) # Disallow lookup deletion & do not delete this rec.
    _updated = models.DateTimeField()
    _updatedby = models.ForeignKey(Person, null=True, db_column='_updatedby', blank=True, related_name='acctupdated_by', on_delete=models.SET_NULL) # Person records shouldn't be deleted, but if they are, preserve this PurchPurchaseAccount entry, and just set this person to null.

    def __unicode__(self):
        return str(self.paid_from_acct.display)
    class Meta:
        db_table = u'purch_purchase_account'

As a last tidbit, did you know that if you don't specify on_delete (or didn't), the default behavior is CASCADE? This means that if someone deleted a gender entry on your Gender table, any Person records with that gender were also deleted!

I would say, "If in doubt, set on_delete=models.PROTECT." Then go test your application. You will quickly figure out which FKs should be labeled the other values without endangering any of your data.

Also, it is worth noting that on_delete=CASCADE is actually not added to any of your migrations, if that is the behavior you are selecting. I guess this is because it is the default, so putting on_delete=CASCADE is the same thing as putting nothing.

please check the jquery mobile scrollstop event

$(document).on("scrollstop",function(){
  alert("Stopped scrolling!");
});

Just adding why and when to use Invoke().

Both Invoke() and BeginInvoke() marshal the code you specify to the dispatcher thread.

But unlike BeginInvoke(), Invoke() stalls your thread until the dispatcher executes your code. You might want to use Invoke() if you need to pause an asynchronous operation until the user has supplied some sort of feedback.

For example, you could call Invoke() to run a snippet of code that shows an OK/Cancel dialog box. After the user clicks a button and your marshaled code completes, the invoke() method will return, and you can act upon the user's response.

Within the range 0 = c < 128, yes the ' is the only difference for CPython 2.6.

>>> set(unichr(c).encode('unicode_escape') for c in range(128)) - set(chr(c).encode('string_escape') for c in range(128))
set(["'"])

Outside of this range the two types are not exchangeable.

>>> '\x80'.encode('string_escape')
'\\x80'
>>> '\x80'.encode('unicode_escape')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can’t decode byte 0x80 in position 0: ordinal not in range(128)

>>> u'1'.encode('unicode_escape')
'1'
>>> u'1'.encode('string_escape')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: escape_encode() argument 1 must be str, not unicode

On Python 3.x, the string_escape encoding no longer exists, since str can only store Unicode.

Another interesting way to do it which would also allow more than just the last number to be taken would be:

int number = 124454;
int overflow = (int)Math.floor(number/(1*10^n))*10^n;

int firstDigits = number - overflow;
//Where n is the number of numbers you wish to conserve</code>

In the above example if n was 1 then the program would return: 4

If n was 3 then the program would return 454

 string[] MultiEmails = email.Split(',');
 foreach (string ToEmail in MultiEmails)
 {
    message.To.Add(new MailAddress(ToEmail)); //adding multiple email addresses
 }

int days = (int) (milliseconds / 86 400 000 )

Short answer: you want to set the handler to a function:

elemm.onclick = function() { alert('blah'); };

Slightly longer answer: you'll have to write a few more lines of code to get that to work consistently across browsers.

The fact is that even the sligthly-longer-code that might solve that particular problem across a set of common browsers will still come with problems of its own. So if you don't care about cross-browser support, go with the totally short one. If you care about it and absolutely only want to get this one single thing working, go with a combination of addEventListener and attachEvent. If you want to be able to extensively create objects and add and remove event listeners throughout your code, and want that to work across browsers, you definitely want to delegate that responsibility to a library such as jQuery.

You would need a mapping provider for MySQL. That is an extra thing the Entity Framework needs to make the magic happen. This blog talks about other mapping providers besides the one Microsoft is supplying. I haven't found any mentionings of MySQL.

Not Obvious, But Fast

f, u = pd.factorize(df.name.values)
counts = np.bincount(f)
u[counts == counts.max()]

array(['alex', 'helen'], dtype=object)

Get a handle to the root ThreadGroup, like this:

ThreadGroup rootGroup = Thread.currentThread().getThreadGroup();
ThreadGroup parentGroup;
while ((parentGroup = rootGroup.getParent()) != null) {
    rootGroup = parentGroup;
}

Now, call the enumerate() function on the root group repeatedly. The second argument lets you get all threads, recursively:

Thread[] threads = new Thread[rootGroup.activeCount()];
while (rootGroup.enumerate(threads, true ) == threads.length) {
    threads = new Thread[threads.length * 2];
}

Note how we call enumerate() repeatedly until the array is large enough to contain all entries.

Run:

go mod init yellow

Then create a file yellow.go:

package yellow

func Mix(s string) string {
   return s + "Yellow"
}

Then create a file orange/orange.go:

package main
import "yellow"

func main() {
   s := yellow.Mix("Red")
   println(s)
}

Then build:

go build

Adding -webkit-transform: translate3d(0,0,0) to an element statically doesn't work for me.

I apply this property dynamically. For example, when a page is scrolled, I set -webkit-transform: translate3d(0,0,0) on a element. Then after a short delay, I reset this property, that is, -webkit-transform: none This approach seems to work.

Thank you, @Colin Williams for pointing me in the right direction.

An easy way to split lists into rows is by floating the individual list items and then the item that you want to go to the next line you can clear the float.

for example

<li style="float: left; display: inline-block"></li>
<li style="float: left; display: inline-block"></li>
<li style="float: left; display: inline-block"></li>

<li style="float: left; display: inline-block; clear: both"></li> --- this will start on a new line
<li style="float: left; display: inline-block"></li>
<li style="float: left; display: inline-block"></li>

I had the same issue, when I tried to update a row:

@Query(value = "UPDATE data SET value = 'asdf'", nativeQuery = true)
void setValue();

My Problem was that I forgot to add the @Modifying annotation:

@Modifying    
@Query(value = "UPDATE data SET value = 'asdf'", nativeQuery = true)
void setValue();

pip install pyopenssl seemed to solve it for me.

You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.

You will then do e.g.:

wget www.google.com

Use '--track' Option

• After a git pull :

  git checkout --track <remote-branch-name>

• Or:

  git fetch && git checkout <branch-name>

If you use the OOP method of inserting, you don't need to worry about mass-action/fillable properties:

$user = new User;
$user->username = 'Stevo';
$user->email = '[email protected]';
$user->password = '45678';
$user->save();

Solution for @umounted answer, because that broke with a one-element tuple, since (1,) is not valid SQL.:

>>> random_ids = [1234,123,54,56,57,58,78,91]
>>> cursor.execute("create table test (id)")
>>> for item in random_ids:
    cursor.execute("insert into test values (%d)" % item)
>>> sublist = [56,57,58]
>>> cursor.execute("select id from test where id in %s" % str(tuple(sublist)).replace(',)',')'))
>>> a = cursor.fetchall()
>>> a
[(56,), (57,), (58,)]

Other solution for sql string:

cursor.execute("select id from test where id in (%s)" % ('"'+'", "'.join(l)+'"'))

The mr utility (a.k.a., myrepos) provides an outstanding solution to this very problem. Install it using your favorite package manager, or just grab the mr script directly from github and put it in $HOME/bin or somewhere else on your PATH. Then, cd to the parent plugins folder shared by these repos and create a basic .mrconfig file with contents similar to the following (adjusting the URLs as needed):

# File: .mrconfig
[cms]
checkout = git clone 'https://<username>@github.com/<username>/cms' 'cms'

[admin]
checkout = git clone 'https://<username>@github.com/<username>/admin' 'admin'

[chart]
checkout = git clone 'https://<username>@github.com/<username>/chart' 'chart'

After that, you can run mr up from the top level plugins folder to pull updates from each repository. (Note that this will also do the initial clone if the target working copy doesn't yet exist.) Other commands you can execute include mr st, mr push, mr log, mr diff, etc—run mr help to see what's possible. There's a mr run command that acts as a pass-through, allowing you to access VCS commands not directly suported by mr itself (e.g., mr run git tag STAGING_081220015). And you can even create your own custom commands that execute arbitrary bits of shell script targeting all repos!

mr is an extremely useful tool for dealing with multiple repos. Since the plugins folder is in your home directory, you might also be interested in vcsh. Together with mr, it provides a powerful mechanism for managing all of your configuration files. See this blog post by Thomas Ferris Nicolaisen for an overview.

I found this page when I was trying to set the backgroundImage attribute of a div, but hadn't wrapped the backgroundImage value with url(). This worked fine:

for (var i=0; i<20; i++) {
  // add a wrapper around an image element
  var wrapper = document.createElement('div');
  wrapper.className = 'image-cell';

  // add the image element
  var img = document.createElement('div');
  img.className = 'image';
  img.style.backgroundImage = 'url(http://via.placeholder.com/350x150)';

  // add the image to its container; add both to the body
  wrapper.appendChild(img);
  document.body.appendChild(wrapper);
}

ErrorDocument 403     /403.html

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

exit code 139 (people say this means memory fragmentation)

No, it means that your program died with signal 11 (SIGSEGV on Linux and most other UNIXes), also known as segmentation fault.

Could anybody tell me why the run fails but debug doesn't?

Your program exhibits undefined behavior, and can do anything (that includes appearing to work correctly sometimes).

Your first step should be running this program under Valgrind, and fixing all errors it reports.

If after doing the above, the program still crashes, then you should let it dump core (ulimit -c unlimited; ./a.out) and then analyze that core dump with GDB: gdb ./a.out core; then use where command.

As of the 0.17.0 release, the sort method was deprecated in favor of sort_values. sort was completely removed in the 0.20.0 release. The arguments (and results) remain the same:

df.sort_values(['a', 'b'], ascending=[True, False])

You can use the ascending argument of sort:

df.sort(['a', 'b'], ascending=[True, False])

For example:

In [11]: df1 = pd.DataFrame(np.random.randint(1, 5, (10,2)), columns=['a','b'])

In [12]: df1.sort(['a', 'b'], ascending=[True, False])
Out[12]:
   a  b
2  1  4
7  1  3
1  1  2
3  1  2
4  3  2
6  4  4
0  4  3
9  4  3
5  4  1
8  4  1

As commented by @renadeen

Sort isn't in place by default! So you should assign result of the sort method to a variable or add inplace=True to method call.

that is, if you want to reuse df1 as a sorted DataFrame:

df1 = df1.sort(['a', 'b'], ascending=[True, False])

or

df1.sort(['a', 'b'], ascending=[True, False], inplace=True)

Take a clone of a remote repository and run git branch -a (to show all the branches git knows about). It will probably look something like this:

* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

Here, master is a branch in the local repository. remotes/origin/master is a branch named master on the remote named origin. You can refer to this as either origin/master, as in:

git diff origin/master..master

You can also refer to it as remotes/origin/master:

git diff remotes/origin/master..master

These are just two different ways of referring to the same thing (incidentally, both of these commands mean "show me the changes between the remote master branch and my master branch).

remotes/origin/HEAD is the default branch for the remote named origin. This lets you simply say origin instead of origin/master.

The XML is most probably invalid.

The problem could be the "&"

$text=preg_replace('/&(?!#?[a-z0-9]+;)/', '&', $text);

will get rid of the "&" and replace it with it's HTML code version...give it a try.

• from a directory_of_modules, you can import a specific_module.py
• this specific_module.py, can contain a Class with some_methods() or just functions()
• from a specific_module.py, you can instantiate a Class or call functions()
• from this Class, you can execute some_method()

Example:

#!/usr/bin/python3
from directory_of_modules import specific_module
instance = specific_module.DbConnect("username","password")
instance.login()

Excerpts from PEP 8 - Style Guide for Python Code:

Modules should have short and all-lowercase names.

Notice: Underscores can be used in the module name if it improves readability.

A Python module is simply a source file(*.py), which can expose:

• Class: names using the "CapWords" convention.

• Function: names in lowercase, words separated by underscores.

• Global Variables: the conventions are about the same as those for Functions.

You can do base64 encoding and decoding with simple javascript.

    $("input").keyup(function () {
     var value = $(this).val(),
         hash = Base64.encode(value);
     $(".test").html(hash);

     var decode = Base64.decode(hash);

To export data to csv/excel from Kibana follow the following steps:-

1. Click on Visualize Tab & select a visualization (if created). If not created create a visualziation.

2. Click on caret symbol (^) which is present at the bottom of the visualization.

3. Then you will get an option of Export:Raw Formatted as the bottom of the page.

Please find below attached image showing Export option after clicking on caret symbol.

Slightly off-topic to your question, but it's probably worth mentioning anyway:

Commons Lang has got some excellent methods you can use in overriding equals and hashcode. Check out EqualsBuilder.reflectionEquals(...) and HashCodeBuilder.reflectionHashCode(...). Saved me plenty of headache in the past - although of course if you just want to do "equals" on ID it may not fit your circumstances.

I also agree that you should use the @Override annotation whenever you're overriding equals (or any other method).

For string concatenation in C++, you should use the + operator.

nametext = "Your name is" + name;

If you are using Linux and you got the permission error, you will need to raise the allowed limit in the /etc/limits.conf or /etc/security/limits.conf file (where the file is located depends on your specific Linux distribution).

For example to allow anyone on the machine to raise their number of open files up to 10000 add the line to the limits.conf file.

* hard nofile 10000

Then logout and relogin to your system and you should be able to do:

ulimit -n 10000

without a permission error.

Can also be done with gsutil du (Yes, a Google Cloud tool)

gsutil du s3://mybucket/ | wc -l

There is a buffer limit of something like 1024. The read will simply hang mid paste or input. To solve this use the -e option.

http://linuxcommand.org/lc3_man_pages/readh.html

-e use Readline to obtain the line in an interactive shell

Change your read to read -e and annoying line input hang goes away.

Django recommend that you use another server to serve static media (another server running on the same machine is fine.) They recommend the use of such servers as lighttp.

This is very simple to set up. However. if 'somefile.txt' is generated on request (content is dynamic) then you may want django to serve it.

The ipv6 localhost is ::1. The unspecified address is ::. This is defined in RFC 4291 section 2.5.

So I need mkdirp() today, and found the solutions on this page overly complicated. Hence I wrote a fairly short snippet, that easily be copied in for others who stumble upon this thread an wonder why we need so many lines of code.

mkdirp.h

#ifndef MKDIRP_H
#define MKDIRP_H

#include <sys/stat.h>

#define DEFAULT_MODE      S_IRWXU | S_IRGRP |  S_IXGRP | S_IROTH | S_IXOTH

/** Utility function to create directory tree */
bool mkdirp(const char* path, mode_t mode = DEFAULT_MODE);

#endif // MKDIRP_H

mkdirp.cpp

#include <errno.h>

bool mkdirp(const char* path, mode_t mode) {
  // const cast for hack
  char* p = const_cast<char*>(path);

  // Do mkdir for each slash until end of string or error
  while (*p != '\0') {
    // Skip first character
    p++;

    // Find first slash or end
    while(*p != '\0' && *p != '/') p++;

    // Remember value from p
    char v = *p;

    // Write end of string at p
    *p = '\0';

    // Create folder from path to '\0' inserted at p
    if(mkdir(path, mode) == -1 && errno != EEXIST) {
      *p = v;
      return false;
    }

    // Restore path to it's former glory
    *p = v;
  }

  return true;
}

If you don't like const casting and temporarily modifying the string, just do a strdup() and free() it afterwards.

I juste wrote a proxy in nodejs that take care of HTTPS with optional decoding of the message. This proxy also can add proxy-authentification header in order to go through a corporate proxy. You need to give as argument the url to find the proxy.pac file in order to configurate the usage of corporate proxy.

The R.utils package has a function called doCall which is like do.call, but it does not return an error if unused arguments are passed.

multiply <- function(a, b) a * b

# these will fail
multiply(a = 20, b = 30, c = 10)
# Error in multiply(a = 20, b = 30, c = 10) : unused argument (c = 10)
do.call(multiply, list(a = 20, b = 30, c = 10))
# Error in (function (a, b)  : unused argument (c = 10)

# R.utils::doCall will work
R.utils::doCall(multiply, args = list(a = 20, b = 30, c = 10))
# [1] 600
# it also does not require the arguments to be passed as a list
R.utils::doCall(multiply, a = 20, b = 30, c = 10)
# [1] 600

I use variations of this all the time to process files...

for files in *.log; do echo "Do stuff with: $files"; echo "Do more stuff with: $files"; done;

If processing lists of files is what you're interested in, look into the -execdir option for files.

here is another easier option

select to_number(column_value) as IDs from xmltable('1,2,3,4,5');

I'm working on the app that validates International Passports (ICAO). We support only english characters. While most foreign national characters can be represented by a character in the Latin alphabet e.g. è by e, there are several national characters that require an extra letter to represent them such as the German umlaut which requires an ‘e’ to be added to the letter e.g. ä by ae.

This is the JavaScript Regex for the first and last names we use:

/^[a-zA-Z '.-]*$/

The max number of characters on the international passport is up to 31. We use maxlength="31" to better word error messages instead of including it in the regex.

Here is a snippet from our code in AngularJS 1.6 with form and error handling:

class PassportController {_x000D_
  constructor() {_x000D_
    this.details = {};_x000D_
    // English letters, spaces and the following symbols ' - . are allowed_x000D_
    // Max length determined by ng-maxlength for better error messaging_x000D_
    this.nameRegex = /^[a-zA-Z '.-]*$/;_x000D_
  }_x000D_
}_x000D_

A quick & concise difference overview :

attr_accessor is an easy way to create read and write accessors in your class. It is used when you do not have a column in your database, but still want to show a field in your forms. This field is a “virtual attribute” in a Rails model.

virtual attribute – an attribute not corresponding to a column in the database.

attr_accessible is used to identify attributes that are accessible by your controller methods makes a property available for mass-assignment.. It will only allow access to the attributes that you specify, denying the rest.

SDL2 (https://www.libsdl.org/) library has two functions implemented across a wide spectrum of platforms:

• SDL_GetBasePath
• SDL_GetPrefPath

So if you don't want to reinvent the wheel... sadly, it means including the entire library, although it's got a quite permissive license and one could also just copy the code. Besides, it provides a lot of other cross-platform functionality.

docker-compose up

$ docker-compose up -d --no-deps --build <service_name>

--no-deps - Don't start linked services.

--build - Build images before starting containers.

I'm just adding another bit of info for others searching for a Scroll-To capability in React. I had tied several libraries for doing Scroll-To for my app, and none worked from my use case until I found react-scrollchor, so I thought I'd pass it on. https://github.com/bySabi/react-scrollchor

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

I struggled with this for a while. Running PHP on the server. This code will post a json and get the json reply from the server

NSURL *url = [NSURL URLWithString:@"http://example.co/index.php"];
NSMutableURLRequest *rq = [NSMutableURLRequest requestWithURL:url];
[rq setHTTPMethod:@"POST"];
NSString *post = [NSString stringWithFormat:@"command1=c1&command2=c2"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding];
[rq setHTTPBody:postData];
[rq setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];

[NSURLConnection sendAsynchronousRequest:rq queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
 {
     if ([data length] > 0 && error == nil){
         NSError *parseError = nil;
         NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:&parseError];
         NSLog(@"Server Response (we want to see a 200 return code) %@",response);
         NSLog(@"dictionary %@",dictionary);
     }
     else if ([data length] == 0 && error == nil){
         NSLog(@"no data returned");
         //no data, but tried
     }
     else if (error != nil)
     {
         NSLog(@"there was a download error");
         //couldn't download

     }
 }];

Based on the accepted solution:

function createTable (tableData) {
  const table = document.createElement('table').appendChild(
    tableData.reduce((tbody, rowData) => {
      tbody.appendChild(
        rowData.reduce((tr, cellData) => {
          tr.appendChild(
            document
              .createElement('td')
              .appendChild(document.createTextNode(cellData))
          )
          return tr
        }, document.createElement('tr'))
      )
      return tbody
    }, document.createElement('tbody'))
  )

  document.body.appendChild(table)
}

createTable([
  ['row 1, cell 1', 'row 1, cell 2'],
  ['row 2, cell 1', 'row 2, cell 2']
])

With a simple change it is possible to return the table as HTML element.

I think you could do it using a specs file.

Under MinGW you could run
gcc -dumpspecs > specs

Where it says

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT}

You change it to

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT} -std=c++11

And then place it in
/mingw/lib/gcc/mingw32/<version>/specs

I'm sure you could do the same without a MinGW build. Not sure where to place the specs file though.

The folder is probably either /gcc/lib/ or /gcc/.

I summarize the answers found in that article:

http://www.quora.com/How-does-MongoDB-compare-to-CouchDB-What-are-the-advantages-and-disadvantages-of-each

MongoDB: Better querying, data storage in BSON (faster access), better data consistency, multiple collections

CouchDB: Better replication, with master to master replication and conflict resolution, data storage in JSON (human-readable, better access through REST services), querying through map-reduce.

So in conclusion, MongoDB is faster, CouchDB is safer.

Also: http://nosql.mypopescu.com/post/298557551/couchdb-vs-mongodb

I adapted @shareef's answer to make it concise. I use,

.sort(function(arg1, arg2) { return arg1.length - arg2.length })

You can do that using the thenAnswer method (when chaining with when):

when(someMock.someMethod()).thenAnswer(new Answer() {
    private int count = 0;

    public Object answer(InvocationOnMock invocation) {
        if (count++ == 1)
            return 1;

        return 2;
    }
});

Or using the equivalent, static doAnswer method:

doAnswer(new Answer() {
    private int count = 0;

    public Object answer(InvocationOnMock invocation) {
        if (count++ == 1)
            return 1;

        return 2;
    }
}).when(someMock).someMethod();

List is an interface, not a concrete class.
An interface is just a set of functions that a class can implement; it doesn't make any sense to instantiate an interface.

ArrayList is a concrete class that happens to implement this interface and all of the methods in it.

If you use Kotlin language you just add this code:

Create global variables of GoogleMap and Marker types.

I use variable marker to make variable marker value can change directly

private lateinit var map: GoogleMap
private lateinit var marker: Marker

And I use this function/method to add the marker on my map:

private fun placeMarkerOnMap(location: LatLng) {
    val markerOptions = MarkerOptions().position(location)
    val titleStr = getAddress(location)
    markerOptions.title(titleStr)
    marker = map.addMarker(markerOptions)
}

After I create the function I place this code on the onMapReady() to remove the marker and create a new one:

map.setOnMapClickListener { location ->
        map.clear()
        marker.remove()
        placeMarkerOnMap(location)
    }

It's bonus if you want to display the address location when you click the marker add this code to hide and show the marker address but you need a method to get the address location. I got the code from this post: How to get complete address from latitude and longitude?

map.setOnMarkerClickListener {marker ->
        if (marker.isInfoWindowShown){
            marker.hideInfoWindow()
        }else{
            marker.showInfoWindow()
        }
        true
    }

Not sure if this answer the question or going to help....

$dt = '6/26/1970' ; // or // '6.26.1970' ;

If you are on MAMP

Check your port number as well generally it is

In your keyPress event handler, write

void ValidateKeyPressHandler(object sender, KeyPressEventArgs e)
{
    var tb = sender as TextBox;
    var startPos = tb.SelectionStart;
    var selLen= tb.SelectionLength;

    var afterEditValue = tb.Text.Remove(startPos, selLen)
                .Insert(startPos, e.KeyChar.ToString()); 
    //  ... more here
}

You can use bcp utility.

To copy the result set from a Transact-SQL statement to a data file, use the queryout option. The following example copies the result of a query into the Contacts.txt data file. The example assumes that you are using Windows Authentication and have a trusted connection to the server instance on which you are running the bcp command. At the Windows command prompt, enter:

bcp "<your query here>" queryout Contacts.txt -c -T

You can use BCP by directly calling as operating sytstem command in SQL Agent job.

Use File Explorer in eclipse. Select Windows => Show View => Other ... => File Explorer.

An another way is pull the file via adb:

adb pull /system/data/data/<yourpackagename>/databases/<databasename> /sdcard

Your array is quite strange : why not just use the key as index, and the value as... the value ?

Wouldn't it be a lot easier if your array was declared like this :

$array = array(
    1 => 'Awaiting for Confirmation', 
    2 => 'Asssigned', 
    3 => 'In Progress', 
    4 => 'Completed', 
    5 => 'Mark As Spam', 
);

That would allow you to use your values of key as indexes to access the array...

And you'd be able to use functions to search on the values, such as array_search() :

$indexCompleted = array_search('Completed', $array);
unset($array[$indexCompleted]);

$indexSpam = array_search('Mark As Spam', $array);
unset($array[$indexSpam]);

var_dump($array);

Easier than with your array, no ?

Instead, with your array that looks like this :

$array = array(
    array('key' => 1, 'value' => 'Awaiting for Confirmation'), 
    array('key' => 2, 'value' => 'Asssigned'), 
    array('key' => 3, 'value' => 'In Progress'), 
    array('key' => 4, 'value' => 'Completed'), 
    array('key' => 5, 'value' => 'Mark As Spam'), 
);

You'll have to loop over all items, to analyse the value, and unset the right items :

foreach ($array as $index => $data) {
    if ($data['value'] == 'Completed' || $data['value'] == 'Mark As Spam') {
        unset($array[$index]);
    }
}
var_dump($array);

Even if do-able, it's not that simple... and I insist : can you not change the format of your array, to work with a simpler key/value system ?

For accessing a shared folder, YOU have to have "Oracle VM extension pack" installed.

Look at the bottom of this link, you can download it from there.

http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html

Uncommenting extension=php_pgsql.dll in the php.ini configuration files does work but, you may have to also restart your XAMPP server to finally get it working. I had to do this.

An easy way that works:

private void dataGrid_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
    foreach (var item in e.AddedCells)
    {
        var col = item.Column as DataGridColumn;
        var fc = col.GetCellContent(item.Item);

        if (fc is CheckBox)
        {
            Debug.WriteLine("Values" + (fc as CheckBox).IsChecked);
        }
        else if(fc is TextBlock)
        {
            Debug.WriteLine("Values" + (fc as TextBlock).Text);
        }
        //// Like this for all available types of cells
    }
}

This worked well for my purpose

$ping = ping -4 $env:COMPUTERNAME
$ip = $ping.Item(2)
$ip = $ip.Substring(11,11)

You can use the BIT field

To create new table:

CREATE TABLE Tb_Table1
(
ID              INT,
BitColumn       BIT DEFAULT 1
)

Adding Column in existing Table:

ALTER TABLE Tb_Table1 ADD BitColumn  BIT DEFAULT 1

To Insert record:

INSERT Tb_Table1 VALUES(11,0)

Here is a simple function to convert Bytes to KB, MB, GB, TB :

# Size in Bytes
$size = 14903511;
# Call this function to convert bytes to KB/MB/GB/TB
echo convertToReadableSize($size);
# Output => 14.2 MB

function convertToReadableSize($size){
  $base = log($size) / log(1024);
  $suffix = array("", "KB", "MB", "GB", "TB");
  $f_base = floor($base);
  return round(pow(1024, $base - floor($base)), 1) . $suffix[$f_base];
}

JavaScript is an object-oriented scripting language that allows you to create dynamic HTML pages, allowing you to process input data and maintain data, usually within the browser.

Java is a programming language, core set of libraries, and virtual machine platform that allows you to create compiled programs that run on nearly every platform, without distribution of source code in its raw form or recompilation.

While the two have similar names, they are really two completely different programming languages/models/platforms, and are used to solve completely different sets of problems.

Also, this is directly from the Wikipedia Javascript article:

A common misconception is that JavaScript is similar or closely related to Java; this is not so. Both have a C-like syntax, are object-oriented, are typically sandboxed and are widely used in client-side Web applications, but the similarities end there. Java has static typing; JavaScript's typing is dynamic (meaning a variable can hold an object of any type and cannot be restricted). Java is loaded from compiled bytecode; JavaScript is loaded as human-readable code. C is their last common ancestor language.

since python 3.5 you can use * iterable unpacking operator:

user_list = [*your_iterator]

but the pythonic way to do it is:

user_list  = list(your_iterator)

You can install pywin32 wheel packages from PYPI with PIP by pointing to this package: https://pypi.python.org/pypi/pypiwin32 No need to worry about first downloading the package, just use pip:

pip install pypiwin32

Currently I think this is "the easiest" way to get in working :) Hope this helps.

For Intellij IDEA Community 2019.1 you will need to follow these steps :

File -> New -> Edit File Templates.. -> Class -> /* Created by ${USER} on ${DATE} */

How about this: It is Somewhat Efficient & Somewhat Simple. Only need to join '2' parts of url path:

def UrlJoin(a , b):
    a, b = a.strip(), b.strip()
    a = a if a.endswith('/') else a + '/'
    b = b if not b.startswith('/') else b[1:]
    return a + b

OR: More Conventional, but Not as efficient if joining only 2 url parts of a path.

def UrlJoin(*parts):
    return '/'.join([p.strip().strip('/') for p in parts])

Test Cases:

>>> UrlJoin('https://example.com/', '/TestURL_1')
'https://example.com/TestURL_1'

>>> UrlJoin('https://example.com', 'TestURL_2')
'https://example.com/TestURL_2'

Note: I may be splitting hairs here, but it is at least good practice and potentially more readable.

I stumbled upon this question trying to identify a clean way to join two assoc arrays.

I was trying to join two different tables that didn't have relationships to each other.

This is what I came up with for PDO Query joining two Tables. Samuel Cook is what identified a solution for me with the array_merge() +1 to him.

        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = "SELECT * FROM ".databaseTbl_Residential_Prospects."";
        $ResidentialData = $pdo->prepare($sql);
        $ResidentialData->execute(array($lapi));
        $ResidentialProspects = $ResidentialData->fetchAll(PDO::FETCH_ASSOC);

        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = "SELECT * FROM ".databaseTbl_Commercial_Prospects."";
        $CommercialData = $pdo->prepare($sql);
        $CommercialData->execute(array($lapi));
        $CommercialProspects = $CommercialData->fetchAll(PDO::FETCH_ASSOC);

        $Prospects = array_merge($ResidentialProspects,$CommercialProspects);
        echo '<pre>';
        var_dump($Prospects);
        echo '</pre>';

Maybe this will help someone else out.

Make sure you set the layout manager for your RecyclerView by:

mRecyclerView.setLayoutManager(new LinearLayoutManager(context));

Instead of LinearLayoutManager, you can use other layout managers too.

Node-ETL package is enough for all BI processing.

npm install node-etl; 

Then :

var ETL=require('node-etl');
var output=ETL.extract('./data.csv',{
              headers:["a","b","c","d"],
              ignore:(line,index)=>index!==0, //ignore first line
 });

Maven absolutely was designed for this type of dependency.

mvn package won't install anything in your local repository it just packages the project and leaves it in the target folder.

Do mvn install in parent project (A), with this all the sub-modules will be installed in your computer's Maven repository, if there are no changes you just need to compile/package the sub-module (B) and Maven will take the already packaged and installed dependencies just right.

You just need to a mvn install in the parent project if you updated some portion of the code.

The pattern is wrong. You have a 3-letter day abbreviation, so it must be EEE. You have a 3-letter month abbreviation, so it must be MMM. As those day and month abbreviations are locale sensitive, you'd like to explicitly specify the SimpleDateFormat locale to English as well, otherwise it will use the platform default locale which may not be English per se.

public static void main(String[] args) throws Exception {
    String target = "Thu Sep 28 20:29:30 JST 2000";
    DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy", Locale.ENGLISH);
    Date result =  df.parse(target);  
    System.out.println(result);
}

This prints here

Thu Sep 28 07:29:30 BOT 2000

which is correct as per my timezone.

I would also reconsider if you wouldn't rather like to use HH instead of kk. Read the javadoc for details about valid patterns.

Check for missing folders that are required by the server, in my case it was UPLOADS folder in programData which was deleted by empty folder cleaner utility that I used earlier.

How did I find out:

run the server config file my.ini(in my case it was in programData) as the defaults-file param for mysqld (don't forget to use --console option to view error log on screen) 'mysqld --defaults-file="C:\ProgramData\MySQL\MySQL Server 8.0\my.ini" --console'

Error:

mysqld: Can't read dir of 'C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\' (OS errno 2 - No such file or directory)

Solution:

Once I manually created the Uploads folder the server started successfully.

Files.write(Paths.get(filepath),texttobewrittentofile,StandardOpenOption.APPEND ,StandardOpenOption.CREATE);    

This creates a file, if it does not exist If files exists, it is uses the existing file and text is appended If you want everyline to be written to the next line add lineSepartor for newline into file.

String texttobewrittentofile = text + System.lineSeparator();

Check out this library: https://github.com/robfig/cron

Example as below:

c := cron.New()
c.AddFunc("0 30 * * * *", func() { fmt.Println("Every hour on the half hour") })
c.AddFunc("@hourly",      func() { fmt.Println("Every hour") })
c.AddFunc("@every 1h30m", func() { fmt.Println("Every hour thirty") })
c.Start()

In order to handle arrays with the $resource service, it's suggested that you use the query method. As you can see below, the query method is built to handle arrays.

    { 'get':    {method:'GET'},
      'save':   {method:'POST'},
      'query':  {method:'GET', isArray:true},
      'remove': {method:'DELETE'},
      'delete': {method:'DELETE'} 
   };

User $resource("apiUrl").query();

I'll disagree with The Tin Man here. I regard rbenv as preferable to RVM. rbenv doesn't interfere drastically with your shell the way RVM does, and it lets you add separate Ruby installations in ordinary folders that you can examine directly. It allows you to compile Ruby yourself. Good outline of the differences here: https://github.com/sstephenson/rbenv/wiki/Why-rbenv%3F

I provide instructions for compiling Ruby 1.9 for rbenv here. Further, more detailed information here. I have used this technique with easy success on Snow Leopard, Lion, and Mountain Lion.

Description:

there are 3 steps to run PHP code inside post or page.

1. In functions.php file (in your theme) add new function

2. In functions.php file (in your theme) register new shortcode which call your function:

add_shortcode( 'SHORCODE_NAME', 'FUNCTION_NAME' );

3. use your new shortcode

Example #1: just display text.

In functions:

function simple_function_1() {
    return "Hello World!";
}

add_shortcode( 'own_shortcode1', 'simple_function_1' );

In post/page:

[own_shortcode1]

Effect:

Hello World!

Example #2: use for loop.

In functions:

function simple_function_2() {
    $output = "";
    
    for ($number = 1; $number < 10; $number++) {    
        // Append numbers to the string
        $output .= "$number<br>";
    } 
    
    return "$output";
}

add_shortcode( 'own_shortcode2', 'simple_function_2' );

In post/page:

[own_shortcode2]

Effect:

1
2
3
4
5
6
7
8
9

Example #3: use shortcode with arguments

In functions:

function simple_function_3($name) {
    return "Hello $name";
}

add_shortcode( 'own_shortcode3', 'simple_function_3' );

In post/page:

[own_shortcode3 name="John"]

Effect:

Hello John

Example #3 - without passing arguments

In post/page:

[own_shortcode3]

Effect:

Hello 

I'd recommend using a CLR user defined function, if you already know how to program in C#, then the code would be;

using System.Data.SqlTypes;
using System.Net;

public partial class UserDefinedFunctions
{
 [Microsoft.SqlServer.Server.SqlFunction]
 public static SqlString http(SqlString url)
 {
  var wc = new WebClient();
  var html = wc.DownloadString(url.Value);
  return new SqlString (html);
 }
}

And here's installation instructions; https://blog.dotnetframework.org/2019/09/17/make-a-http-request-from-sqlserver-using-a-clr-udf/

Try this:

 DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
 int day = datePicker.getDayOfMonth();
 int month = datePicker.getMonth() + 1;
 int year = datePicker.getYear();

Could you do something like this:

var index = Array.prototype.slice.call(element.parentElement.children).indexOf(element);

https://developer.mozilla.org/en-US/docs/Web/API/Node/parentElement

In CentOS 6(tested on Centos 7 too) you can't set short_open_tag in /etc/php.ini for php-fpm. You will have error:

ERROR: [/etc/php.ini:159] unknown entry 'short_open_tag'
ERROR: Unable to include /etc/php.ini from /etc/php-fpm.conf at line 159
ERROR: failed to load configuration file '/etc/php-fpm.conf'
ERROR: FPM initialization failed

You must edit config for your site, which can found in /etc/php-fpm.d/www.conf And write at end of file:

php_value[short_open_tag] =  On

what about this simple inArray function:

Function isInArray(ByRef stringToBeFound As String, ByRef arr As Variant) As Boolean
For Each element In arr
    If element = stringToBeFound Then
        isInArray = True
        Exit Function
    End If
Next element
End Function

if let url = URL(string: "fb://profile/<id>") {
        if #available(iOS 10, *) {
            UIApplication.shared.open(url, options: [:],completionHandler: { (success) in
                print("Open fb://profile/<id>: \(success)")
            })
        } else {
            let success = UIApplication.shared.openURL(url)
            print("Open fb://profile/<id>: \(success)")
        }
 }

Assuming this branch isn't an external or a symlink, removing the branch should be as simple as:

svn rm branches/< mybranch >

svn ci -m "message"

If you'd like to do this in the repository then update to remove it from your working copy you can do something like:

svn rm http://< myurl >/< myrepo >/branches/< mybranch >

Then run:

svn update

Use the .Clear method.

Sheets("Test").Range("A1:C3").Clear

MSDN documentation here.

Like all enum instances, Java instantiates each object when the class is loaded, with some guarantee that it's instantiated exactly once per JVM. Think of the INSTANCE declaration as a public static final field: Java will instantiate the object the first time the class is referred to.

The instances are created during static initialization, which is defined in the Java Language Specification, section 12.4.

For what it's worth, Joshua Bloch describes this pattern in detail as item 3 of Effective Java Second Edition.

While they are both rooted in C, they are two completely different languages.

A major difference is that Objective-C is focused on runtime-decisions for dispatching and heavily depends on its runtime library to handle inheritance and polymorphism, while in C++ the focus usually lies on static, compile time, decisions.

Regarding libraries, you can use plain C libraries in both languages - but their native libraries are completely different.

Of interest though is that you can mix both languages (with some limitations). The result is called Objective-C++.

Give something like this a try:

$(document).ready(function(){
    $("#thisTable tr").click(function(){
        $(this).find("td").each(function(){
            alert($(this).html());
        });
    });
});?

Here is a fiddle of the code in action: http://jsfiddle.net/YhZsW/

Swift 4,

private func callNumber(phoneNumber:String) {

    if let phoneCallURL = URL(string: "telprompt://\(phoneNumber)") {

        let application:UIApplication = UIApplication.shared
        if (application.canOpenURL(phoneCallURL)) {
            if #available(iOS 10.0, *) {
                application.open(phoneCallURL, options: [:], completionHandler: nil)
            } else {
                // Fallback on earlier versions
                 application.openURL(phoneCallURL as URL)

            }
        }
    }
}

I am working through the same need and I believe your timeframe is incorrect.

Try these:

• 15min change: find . -mtime -.01
• 1hr change: find . -mtime -.04
• 12 hr change: find . -mtime -.5

You should be using 24 hours as your base. The number after -mtime should be relative to 24 hours. Thus -.5 is the equivalent of 12 hours, because 12 hours is half of 24 hours.

if you look to support old version pre lolipop

use the same xml code with some changes

instead of normal ImageView --> AppCompatImageView

instead of android:src --> app:srcCompat

here is example

<android.support.v7.widget.AppCompatImageView
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/button"
        app:srcCompat="@drawable/ic_more_vert_24dp"
        android:tint="@color/primary" />

dont forget update your gradle as @ Sayooj Valsan mention

// Gradle Plugin 2.0+  
 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
   }  
 }  

 compile 'com.android.support:design:23.4.0'

Notice To any one use vector dont ever ever never give your vector reference to color like this one android:fillColor="@color/primary" give its hex value .

DDL is Data Definition Language: Just think you are defining the DB. So we use CREATE,ALTER TRUNCATE commands.
DML is after defining we are Manipulating the data. So we use SELECT,INSERT, UPDATE, DELETE command.

Remember DDL commands are auto-committed. You don't need to use COMMIT statements.
DML (Data Manipulation Language) commands need to be commited/rolled back.

Remove these two lines:

xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");

XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.

I had this issue as well, and the text-shadow wasn't an option because the corners would look bad (unless I had many many shadows), and I didn't want any blur, therefore my only other option was to do the following: Have 2 divs, and for the background div, put a -webkit-text-stroke on it, which then allows for as big of an outline as you like.

div {_x000D_
  font-size: 200px;_x000D_
  position: absolute;_x000D_
  white-space: nowrap;_x000D_
}_x000D_
_x000D_
.front {_x000D_
 color: blue;_x000D_
}_x000D_
_x000D_
.outline {_x000D_
  -webkit-text-stroke: 30px red;_x000D_
  user-select: none;_x000D_
}

<div class="outline">_x000D_
 outline text_x000D_
</div>_x000D_
_x000D_
<div class="front">_x000D_
 outline text_x000D_
</div>  

Using this, I was able to achieve an outline, because the stroke-width method was not an option if you want your text to remain legible with a very large outline (because with stroke-width the outline will start inside the lettering which makes it not legible when the width gets larger than the letters.

Note: the reason I needed such a fat outline was I was emulating the street labels in "google maps" and I wanted a fat white halo around the text. This solution worked perfectly for me.

Here is a fiddle showing this solution

Install a trap handler to catch SIGINT, which kills off your child process if it's still alive, though other posters are correct that it won't catch SIGKILL.

Open a .lockfile with exclusive access and have the child poll on it trying to open it - if the open succeeds, the child process should exit

Find the Run button present on the top of the Eclipse, then select Run Configuration -> Arguments, in VM arguments section just mention the heap size you want to extend as below:

-Xmx1024m

Here is an example. Run it. Then change one of the notifyAll() to notify() and see what happens.

            try {
                Thread.sleep(random.nextInt(100));
            } catch (InterruptedException e) { }
        }
    }
}

Producer class

import java.util.Random;

public class Producer implements Runnable {

    private Dropbox dropbox;

    public Producer(Dropbox dropbox) {
        this.dropbox = dropbox;
    }

    public void run() {
        Random random = new Random();
        while (true) {
            int number = random.nextInt(10);
            try {
                Thread.sleep(random.nextInt(100));
                dropbox.put(number);
            } catch (InterruptedException e) { }
        }
    }
}

you can get the date like this. eg:- Users table

id name created_at
1  abc  2017-09-16
2  xyz  2017-06-10

you can get the monthname like this

select year(created_at), monthname(created_at) from users;

output

+-----------+-------------------------------+
| year(created_at) | monthname(created_at)  |
+-----------+-------------------------------+
|      2017        | september              |
|      2017        | june                   |

Use position:fixed on the video, set it to 100% width/height, and put a negative z-index on it so it appears behind everything.

If you look at VideoJS, the controls are just html elements sitting on top of the video, using z-index to make sure they're above.

HTML

<video id="video_background" src="video.mp4" autoplay>

(Add webm and ogg sources to support more browsers)

CSS

#video_background {
  position: fixed;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  z-index: -1000;
}

It'll work in most HTML5 browsers, but probably not iPhone/iPad, where the video needs to be activated, and doesn't like elements over it.

If you wanted a looser criterion for rejection, for example, to reject empty strings as well as nil, you could use:

[1, nil, 3, 0, ''].reject(&:blank?)
 => [1, 3, 0] 

If you wanted to go further and reject zero values (or apply more complex logic to the process), you could pass a block to reject:

[1, nil, 3, 0, ''].reject do |value| value.blank? || value==0 end
 => [1, 3]

[1, nil, 3, 0, '', 1000].reject do |value| value.blank? || value==0 || value>10 end
 => [1, 3]

A good practice is write text inside String.xml

example:

String.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="yellow">Yellow</string>
</resources>

and inside layout:

<TextView android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:text="@string/yellow" />

You can also use EXIT_SUCCESS instead of return 0;. The macro EXIT_SUCCESS is actually defined as zero, but makes your program more readable.

You can also call the "host" command from the PowerShell commandline. It should give you the value of the $host variable.

Relying on the internal representation of decimals is not cool.

How about this:

    int CountDecimalDigits(decimal n)
    {
        return n.ToString(System.Globalization.CultureInfo.InvariantCulture)
                //.TrimEnd('0') uncomment if you don't want to count trailing zeroes
                .SkipWhile(c => c != '.')
                .Skip(1)
                .Count();
    }

echo file_get_contents('http://localhost/web/a.php'); //Best Example

Eg: Add data:-

   Bundle bundle = new Bundle();
   bundle.putString("latitude", latitude);
   bundle.putString("longitude", longitude);
   bundle.putString("board_id", board_id);
   MapFragment mapFragment = new MapFragment();
   mapFragment.setArguments(bundle);

Eg: Get data :-

String latitude =  getArguments().getString("latitude")

have at look at the static methods DateTime.Parse() and DateTime.TryParse(). They will allow you to pass in your date string and a format string, and get a DateTime object in return.

Hope this will work:

// create activity indicator 
UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] 
    initWithFrame:CGRectMake(0.0f, 0.0f, 20.0f, 20.0f)];
[activityIndicator setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleWhite];

...
 [self.view addSubview:activityIndicator];
// release it
[activityIndicator release];

If you're going to access your local computer (or any computer) using UNC, you'll need to setup a share. If you haven't already setup a share, you could use the default administrative shares. Example:

\\localhost\c$\my_dir

... accesses a folder called "my_dir" via UNC on your C: drive. By default all the hard drives on your machine are shared with hidden shares like c$, d$, etc.
