My solution is similar to Payam's, except I am using

//older code
//postman.setGlobalVariable("currentDate", new Date().toLocaleDateString());
pm.globals.set("currentDate", new Date().toLocaleDateString());

If you hit the "3 dots" on the folder and click "Edit"

Then set Pre-Request Scripts for the all calls, so the global variable is always available.

Using contentView (UView) as container inside UIScrollView, stick to edges (top, bottom, trailing, leading) of superview (UIScrollView) and contentView should have equalwidth and equalheight to superview. Those are constraints. And call of method:

-(void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    self.scrollView.contentSize = self.contentView.frame.size;
}

Solved issues for me.

you can also use:

SELECT CASE
         WHEN upper(t.name) like 'P%' THEN
          'productive'
         WHEN upper(t.name) like 'T%' THEN
          'test'
         WHEN upper(t.name) like 'D%' THEN
          'development'
         ELSE
          'unknown'
       END as type
FROM table t

You forgot the table in your syntax:

drop table [table_name]

which drops a table.

Using

drop table if exists [table_name]

checks if the table exists before dropping it.
If it exists, it gets dropped.
If not, no error will be thrown and no action be taken.

You don't have a field named user_email in the members table ... as for why, I'm not sure as the code "looks" like it should try to join on different fields

Does the Auth::attempt method perform a join of the schema? Run grep -Rl 'class Auth' /path/to/framework and find where the attempt method is and what it does.

You can commit your existing container (that is create a new image from container’s changes) and then run it with your new mounts.

Example:

$ docker ps  -a
CONTAINER ID        IMAGE                 COMMAND                  CREATED              STATUS                          PORTS               NAMES
    5a8f89adeead        ubuntu:14.04          "/bin/bash"              About a minute ago   Exited (0) About a minute ago                       agitated_newton

$ docker commit 5a8f89adeead newimagename

$ docker run -ti -v "$PWD/somedir":/somedir newimagename /bin/bash

If it's all OK, stop your old container, and use this new one.

That´s it :)

Be careful if you use fat arrow functions as you will get undefined for this.id Wasted 10 minutes today wondering what the hell was going on

Have you tried to check if

Go to the Eclipse base folder ? open eclipse.ini ? you will find the below line at line no 4:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20150204-1316 plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120913-144807

As you can see, line 1 is of 64-bit Eclipse. It contains x86_64 and line 2 is of 32-bit Eclipse. It contains x_86.

For 32-bit Eclipse only x86 will be present and for 64-bit Eclipse x86_64 will be present.

I used KooiInc's function listed above but I had to use two different input types one 'button' for IE and one 'submit' for FireFox. I am not exactly sure why but it works.

// HTML

<input type="button" id="btnEmailHidden" style="display:none" />
<input type="submit" id="btnEmailHidden2" style="display:none" />

// in JavaScript

var hiddenBtn = document.getElementById("btnEmailHidden");

if (hiddenBtn.fireEvent) {
    hiddenBtn.fireEvent('onclick');
    hiddenBtn[eType]();
}
else {
    // dispatch for firefox + others
    var evObj = document.createEvent('MouseEvent');
    evObj.initEvent(eType, true, true);
    var hiddenBtn2 = document.getElementById("btnEmailHidden2");
    hiddenBtn2.dispatchEvent(evObj);
}

I have search and tried many suggestions but this is what ended up working. If I had some more time I would have liked to investigate why submit works with FF and button with IE but that would be a luxury right now so on to the next problem.

Another aspect is security (obfuscation). Once a piece of code is extracted from the main application and put in a "separated" Dynamic-Link Library, it is easier to attack, analyse (reverse-engineer) the code, since it has been isolated. When the same piece of code is kept in a LIB Library, it is part of the compiled (linked) target application, and this thus harder to isolate (differentiate) that piece of code from the rest of the target binaries.

This could also happens if you put a @PreAuthorize or @PostAuthorize in a Bean in creation. I would recommend to move such annotations to methods of interest.

Map reduce is a framework that was developed to process massive amounts of data efficiently. For example, if we have 1 million records in a dataset, and it is stored in a relational representation - it is very expensive to derive values and perform any sort of transformations on these.

For Example In SQL, Given the Date of Birth, to find out How many people are of age > 30 for a million records would take a while, and this would only increase in order of magnitute when the complexity of the query increases. Map Reduce provides a cluster based implementation where data is processed in a distributed manner

Here is a wikipedia article explaining what map-reduce is all about

Another good example is Finding Friends via map reduce can be a powerful example to understand the concept, and a well used use-case.

Personally, found this link quite useful to understand the concept

Copying the explanation provided in the blog (In case the link goes stale)

Finding Friends

MapReduce is a framework originally developed at Google that allows for easy large scale distributed computing across a number of domains. Apache Hadoop is an open source implementation.

I'll gloss over the details, but it comes down to defining two functions: a map function and a reduce function. The map function takes a value and outputs key:value pairs. For instance, if we define a map function that takes a string and outputs the length of the word as the key and the word itself as the value then map(steve) would return 5:steve and map(savannah) would return 8:savannah. You may have noticed that the map function is stateless and only requires the input value to compute it's output value. This allows us to run the map function against values in parallel and provides a huge advantage. Before we get to the reduce function, the mapreduce framework groups all of the values together by key, so if the map functions output the following key:value pairs:

3 : the
3 : and
3 : you
4 : then
4 : what
4 : when
5 : steve
5 : where
8 : savannah
8 : research

They get grouped as:

3 : [the, and, you]
4 : [then, what, when]
5 : [steve, where]
8 : [savannah, research]

Each of these lines would then be passed as an argument to the reduce function, which accepts a key and a list of values. In this instance, we might be trying to figure out how many words of certain lengths exist, so our reduce function will just count the number of items in the list and output the key with the size of the list, like:

3 : 3
4 : 3
5 : 2
8 : 2

The reductions can also be done in parallel, again providing a huge advantage. We can then look at these final results and see that there were only two words of length 5 in our corpus, etc...

The most common example of mapreduce is for counting the number of times words occur in a corpus. Suppose you had a copy of the internet (I've been fortunate enough to have worked in such a situation), and you wanted a list of every word on the internet as well as how many times it occurred.

The way you would approach this would be to tokenize the documents you have (break it into words), and pass each word to a mapper. The mapper would then spit the word back out along with a value of 1. The grouping phase will take all the keys (in this case words), and make a list of 1's. The reduce phase then takes a key (the word) and a list (a list of 1's for every time the key appeared on the internet), and sums the list. The reducer then outputs the word, along with it's count. When all is said and done you'll have a list of every word on the internet, along with how many times it appeared.

Easy, right? If you've ever read about mapreduce, the above scenario isn't anything new... it's the "Hello, World" of mapreduce. So here is a real world use case (Facebook may or may not actually do the following, it's just an example):

Facebook has a list of friends (note that friends are a bi-directional thing on Facebook. If I'm your friend, you're mine). They also have lots of disk space and they serve hundreds of millions of requests everyday. They've decided to pre-compute calculations when they can to reduce the processing time of requests. One common processing request is the "You and Joe have 230 friends in common" feature. When you visit someone's profile, you see a list of friends that you have in common. This list doesn't change frequently so it'd be wasteful to recalculate it every time you visited the profile (sure you could use a decent caching strategy, but then I wouldn't be able to continue writing about mapreduce for this problem). We're going to use mapreduce so that we can calculate everyone's common friends once a day and store those results. Later on it's just a quick lookup. We've got lots of disk, it's cheap.

Assume the friends are stored as Person->[List of Friends], our friends list is then:

A -> B C D
B -> A C D E
C -> A B D E
D -> A B C E
E -> B C D

Each line will be an argument to a mapper. For every friend in the list of friends, the mapper will output a key-value pair. The key will be a friend along with the person. The value will be the list of friends. The key will be sorted so that the friends are in order, causing all pairs of friends to go to the same reducer. This is hard to explain with text, so let's just do it and see if you can see the pattern. After all the mappers are done running, you'll have a list like this:

For map(A -> B C D) :

(A B) -> B C D
(A C) -> B C D
(A D) -> B C D

For map(B -> A C D E) : (Note that A comes before B in the key)

(A B) -> A C D E
(B C) -> A C D E
(B D) -> A C D E
(B E) -> A C D E
For map(C -> A B D E) :

(A C) -> A B D E
(B C) -> A B D E
(C D) -> A B D E
(C E) -> A B D E
For map(D -> A B C E) :

(A D) -> A B C E
(B D) -> A B C E
(C D) -> A B C E
(D E) -> A B C E
And finally for map(E -> B C D):

(B E) -> B C D
(C E) -> B C D
(D E) -> B C D
Before we send these key-value pairs to the reducers, we group them by their keys and get:

(A B) -> (A C D E) (B C D)
(A C) -> (A B D E) (B C D)
(A D) -> (A B C E) (B C D)
(B C) -> (A B D E) (A C D E)
(B D) -> (A B C E) (A C D E)
(B E) -> (A C D E) (B C D)
(C D) -> (A B C E) (A B D E)
(C E) -> (A B D E) (B C D)
(D E) -> (A B C E) (B C D)

Each line will be passed as an argument to a reducer. The reduce function will simply intersect the lists of values and output the same key with the result of the intersection. For example, reduce((A B) -> (A C D E) (B C D)) will output (A B) : (C D) and means that friends A and B have C and D as common friends.

The result after reduction is:

(A B) -> (C D)
(A C) -> (B D)
(A D) -> (B C)
(B C) -> (A D E)
(B D) -> (A C E)
(B E) -> (C D)
(C D) -> (A B E)
(C E) -> (B D)
(D E) -> (B C)

Now when D visits B's profile, we can quickly look up (B D) and see that they have three friends in common, (A C E).

I implemented Joe White's solution, but ran into problems with occasional "DialogResult can be set only after Window is created and shown as dialog" errors.

I was keeping the ViewModel around after the View was closed and occasionally I later opened a new View using the same VM. It appears that closing the new View before the old View had been garbage collected resulted in DialogResultChanged trying to set the DialogResult property on the closed window, thus provoking the error.

My solution was to change DialogResultChanged to check the window's IsLoaded property:

private static void DialogResultChanged(
    DependencyObject d,
    DependencyPropertyChangedEventArgs e)
{
    var window = d as Window;
    if (window != null && window.IsLoaded)
        window.DialogResult = e.NewValue as bool?;
}

After making this change any attachments to closed dialogs are ignored.

There is another option which i haven't seen here and which doesn't involve "complex" Objects or Collections.

String[] array1 = new String[]{"one", "two"};
String[] array2 = new String[]{"three"};
String[] array = new String[array1.length + array2.length];
System.arraycopy(array1, 0, array, 0, array1.length);
System.arraycopy(array2, 0, array, array1.length, array2.length);

I have had the exact same problem with a solution, that System.Windows.Interactivity was required for one of the project in Visual Studio 2019, and I tried to install Blend for Visual Studio SDK for .NET from Visual Studio 2019 Individual components, but it did not exist in it.

The consequence of that, I was not able to build the project in my solution with repetitive of following similar error on different XAML parts of the project:

The tag 'Interaction.Behaviors' does not exist in XML namespace 'clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity'.

The above mentioned errors snapshot example

The solution, the way I solved it, is by installing Microsoft Expression Blend Software Development Kit (SDK) for .NET 4 from Microsoft.

Thanks to my colleague @felza, mentioned that System.Windows.Interactivity requires this sdk, that is suppose to be located in this folder:

C:\Program Files (x86)\Microsoft SDKs\Expression\Blend\.NETFramework\v4.0

In my case it was not installed. I have had this folder C:\Program Files (x86)\Microsoft SDKs with out Expression\Blend\.NETFramework\v4.0 folder inside it.

After installing it, all errors disappeared.

Adding to @David Roussel answer, classes may be loaded by multiple class loaders.

Lets understand how class loader works.

From javin paul blog in javarevisited :

ClassLoader follows three principles.

Delegation principle

A class is loaded in Java, when its needed. Suppose you have an application specific class called Abc.class, first request of loading this class will come to Application ClassLoader which will delegate to its parent Extension ClassLoader which further delegates to Primordial or Bootstrap class loader

• Bootstrap ClassLoader is responsible for loading standard JDK class files from rt.jar and it is parent of all class loaders in Java. Bootstrap class loader don't have any parents.

• Extension ClassLoader delegates class loading request to its parent, Bootstrap and if unsuccessful, loads class form jre/lib/ext directory or any other directory pointed by java.ext.dirs system property

• System or Application class loader and it is responsible for loading application specific classes from CLASSPATH environment variable, -classpath or -cp command line option, Class-Path attribute of Manifest file inside JAR.

• Application class loader is a child of Extension ClassLoader and its implemented by sun.misc.Launcher$AppClassLoader class.

NOTE: Except Bootstrap class loader, which is implemented in native language mostly in C, all Java class loaders are implemented using java.lang.ClassLoader.

Visibility Principle

According to visibility principle, Child ClassLoader can see class loaded by Parent ClassLoader but vice-versa is not true.

Uniqueness Principle

According to this principle a class loaded by Parent should not be loaded by Child ClassLoader again

You want code which produce string from arrayList,

Iterate through all elements in list and add it to your String result

you can do this in 2 ways: using String as result or StringBuffer/StringBuilder.

Example:

String result = "";
for (String s : list) {
    result += s;
}

...but this isn't good practice because of performance reason. Better is using StringBuffer (threads safe) or StringBuilder which are more appropriate to adding Strings

Try this:

document.getElementById('*spaM4').textContent

If you need to target < IE9 then you need to use .innerText

Specify complete path and grant proper permission to scriptfile. I tried following script file to run through cron:

#!/bin/bash
/bin/mkdir /scratch/ofsaaweb/CHEF_FICHOME/ficdb/bin/crondir

And crontab command is

* * * * * /bin/bash /scratch/ofsaaweb/CHEF_FICHOME/ficdb/bin/test.sh

It worked for me.

Use the Set#toArray(IntFunction<T[]>) method taking an IntFunction as generator.

String[] GPXFILES1 = myset.toArray(String[]::new);

If you're not on Java 11 yet, then use the Set#toArray(T[]) method taking a typed array argument of the same size.

String[] GPXFILES1 = myset.toArray(new String[myset.size()]);

While still not on Java 11, and you can't guarantee that myset is unmodifiable at the moment of conversion to array, then better specify an empty typed array.

String[] GPXFILES1 = myset.toArray(new String[0]);

The error message says it all: your connection timed out. This means your request did not get a response within some (default) timeframe. The reasons that no response was received is likely to be one of:

• a) The IP/domain or port is incorrect
• b) The IP/domain or port (i.e service) is down
• c) The IP/domain is taking longer than your default timeout to respond
• d) You have a firewall that is blocking requests or responses on whatever port you are using
• e) You have a firewall that is blocking requests to that particular host
• f) Your internet access is down

Note that firewalls and port or IP blocking may be in place by your ISP

If you have a solution which contains for example Web Application and Test Project, you probably want that Test Project uses Web Application's web.config.

One way to solve it is to copy web.config to test project and rename it as app.config.

Another and better solution is to modify build chain and make it to make automatic copy of web.config to test projects output directory. To do that, right click Test Application and select properties. Now you should see project properties. Click "Build Events" and then click "Edit Post-build..." button. Write following line to there:

copy "$(SolutionDir)\WebApplication1\web.config" "$(ProjectDir)$(OutDir)$(TargetFileName).config"

And click OK. (Note you most probably need to change WebApplication1 as you project name which you want to test). If you have wrong path to web.config then copy fails and you will notice it during unsuccessful build.

Edit:

To Copy from the current Project to the Test Project:

copy "$(ProjectDir)bin\WebProject.dll.config" "$(SolutionDir)WebProject.Tests\bin\Debug\App.Config"

Got hit by the same issue while accessing SQLServer from IIS. Adding TrustServerCertificate=True didnot help.

Could see a comment in MS docs: Make sure the SQLServer service account has access to the TLS Certificate you are using. (NT Service\MSSQLSERVER)

Open personal store and right click on the certificate -> manage private keys -> Add the SQL service account and give full control.

Restart the SQL service. It worked.

you can try in this way if you are using thymeleaf

sec:authorize="hasAnyRole(T(com.orsbv.hcs.model.SystemRole).ADMIN.getName(),
               T(com.orsbv.hcs.model.SystemRole).SUPER_USER.getName(),'ROLE_MANAGEMENT')"

this will return true if the user has the mentioned roles,false otherwise.

Please note you have to use sec tag in your html declaration tag like this

<html xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

Most generally (in case of jupyter not being in /local/bin) use,

which jupyter

Example output

~/miniconda3/bin/jupyter

to see the path for jupyter, then explicitly use that path with sudo

sudo ~/miniconda3/bin/jupyter 

Select Case parameter 
    ' does something here. 
    ' does something here. 
    Case "userID", "packageID", "mvrType" 
        If otherFactor Then 
            ' does something here. 
        Else 
            goto case default 
        End If 
    Case Else

        Exit Select 
End Select

Can you post that cursor example or link to the question? There's probably an even better way than a recursive CTE.

In addition to other comments, cursors when used improperly (which is often) cause unnecessary page/row locks.

You can try to prevent default handler:

html:

<button ng-click="saveUser($event)">

js:

$scope.saveUser = function (event) {
  event.preventDefault();
  // your code
}

To go end of the file: press ESC

1) type capital G (Capital G)

2) press shift + g (small g)

To go top of the file there are the following ways: press ESC

1) press 1G (Capital G)

2) press gg (small g) or 1gg

3) You can jump to the particular line number,e.g wanted to go 1 line number, press 1 + G

You didn't give us much to go on here, but I think you're just asking how to add content to the beginning or end of an element? If so here's how you can do it pretty easily:

//get the target div you want to append/prepend to
var someDiv = document.getElementById("targetDiv");

//append text
someDiv.innerHTML += "Add this text to the end";

//prepend text
someDiv.innerHTML = "Add this text to the beginning" + someDiv.innerHTML;

Pretty easy.

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.

main.c has a main wrapper like this:

#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
  // the true main() routine.
}

spi.c, serial.c and usb.c have main wrappers for their respective test code like this:

#ifdef TEST_USB
int main(int argc, char *argv[]) {
  // the  main() routine for testing the usb code.
}

config.h Which is included by all the c files has an entry like this:

// Uncomment below to test the serial
//#define TEST_SERIAL


// Uncomment below to test the spi code
//#define TEST_SPI

// Uncomment below to test the usb code
#define TEST_USB

If you are only looking to replace all occurrences of "< " (with space) with "<" (no space), then you can do an lapply over the data frame, with a gsub for replacement:

> data <- data.frame(lapply(data, function(x) {
+                  gsub("< ", "<", x)
+              }))
> data
  name var1 var2
1    a   <2   <3
2    a   <2   <3
3    a   <2   <3
4    b   <2   <3
5    b   <2   <3
6    b   <2   <3
7    c   <2   <3
8    c   <2   <3
9    c   <2   <3

This is how the regex look like:

import re
# "semicolon or (a comma followed by a space)"
pattern = re.compile(r";|, ")

# "(semicolon or a comma) followed by a space"
pattern = re.compile(r"[;,] ")

print pattern.split(text)

This might be a problem of your .sql file size.

If you are using xampp. Go to the xampp control panel -> Click MySql config -> Open my.ini.

Today I still use editable="false", but also with focusable="false".

I think the case we need to make an EditText un-editable, is because we want to keep its EditText style (with that underline, with hint, etc), but it accepts other inputs instead of text. For example a dropdown list.

In such use case, we need to have the EditText clickable (thus enabled="false" is not suitable). Setting focusable="false" do this trick, however, I can still long hold on the EditText and paste my own text onto it from clipboard. Depending on your code and handling this can even crash your app.

So I also used editable="false" and now everything is great, except the warning.

A small update to what @control freak and @skatun wrote previously (sorry I don't have enough reputation to just make a comment). I used skatun's code and it worked well for me except that it was creating a larger array than what I needed. Therefore, I changed:

ReDim aPreservedArray(nNewFirstUBound, nNewLastUBound)

to:

ReDim aPreservedArray(LBound(aArrayToPreserve, 1) To nNewFirstUBound, LBound(aArrayToPreserve, 2) To nNewLastUBound)

This will maintain whatever the original array's lower bounds were (either 0, 1, or whatever; the original code assumes 0) for both dimensions.

DO it like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$yourPHPVAR%'");

Do not forget the % at the end

Imagine you have a window open on http://www.foo.com/bar/page.html In all of them (HTML, Javascript and CSS):

opened_url = http://www.foo.com/bar/page.html
base_path = http://www.foo.com/bar/
home_path = http://www.foo.com/
/kitten.png = Home_path/kitten.png
kitten.png = Base_path/kitten.png

In HTML and Javascript, the base_path is based on the opened window. In big javascript projects you need a BASEPATH or root variable to store the base_path occasionally. (like this)

In CSS the opened url is the address of which your .css is stored or loaded, its not the same like javascript with current opened window in this case.

And for being more secure in absolute paths it is recommended to use // instead of http:// for possible future migrations to https://. In your own example, use it this way:

<img src="//www.foo.com/images/kitten.png">

I use an immediately invoked lambda for these scenarios:

const config = (() => {
  try {
    return JSON.parse(fs.readFileSync('config.json'));
  } catch (error) {
    return {};
  }
})();

async version:

const config = await (async () => {
  try {
    return JSON.parse(await fs.readFileAsync('config.json'));
  } catch (error) {
    return {};
  }
})();

This way is faster than the nested list comprehensions

[x[:] for x in [[foo] * 10] * 10]    # for immutable foo!

Here are some python3 timings, for small and large lists

$python3 -m timeit '[x[:] for x in [[1] * 10] * 10]'
1000000 loops, best of 3: 1.55 usec per loop

$ python3 -m timeit '[[1 for i in range(10)] for j in range(10)]'
100000 loops, best of 3: 6.44 usec per loop

$ python3 -m timeit '[x[:] for x in [[1] * 1000] * 1000]'
100 loops, best of 3: 5.5 msec per loop

$ python3 -m timeit '[[1 for i in range(1000)] for j in range(1000)]'
10 loops, best of 3: 27 msec per loop

Explanation:

[[foo]*10]*10 creates a list of the same object repeated 10 times. You can't just use this, because modifying one element will modify that same element in each row!

x[:] is equivalent to list(X) but is a bit more efficient since it avoids the name lookup. Either way, it creates a shallow copy of each row, so now all the elements are independent.

All the elements are the same foo object though, so if foo is mutable, you can't use this scheme., you'd have to use

import copy
[[copy.deepcopy(foo) for x in range(10)] for y in range(10)]

or assuming a class (or function) Foo that returns foos

[[Foo() for x in range(10)] for y in range(10)]

If you want to kill -9 based on a string (you might want to try kill first) you can do something like this:

ps axf | grep <process name> | grep -v grep | awk '{print "kill -9 " $1}'

This will show you what you're about to kill (very, very important) and just pipe it to sh when the time comes to execute:

ps axf | grep <process name> | grep -v grep | awk '{print "kill -9 " $1}' | sh

You can also try ExcelPython which allows you to manipulate Python object and call code from VBA.

You need to use runat="server" like this:

<textarea id="TextArea1" cols="20" rows="2" runat="server"></textarea>

You can use the runat=server attribute with any standard HTML element, and later use it from codebehind.

You have to remove the semicolon in the css rule string:

$(this).parent().css("background", "url(/images/r-srchbg_white.png) no-repeat");

1) remove the apk from this directory project/build/outputs/apk

2) If you using genymotion emulator restart the genymotion

3) make project & rebuild the project

4) Run Again

I would like to add a word of warning when you are dealing with C++11-style allocator-aware containers. Swapping and assignment have subtly different semantics.

For concreteness, let us consider a container std::vector<T, A>, where A is some stateful allocator type, and we'll compare the following functions:

void fs(std::vector<T, A> & a, std::vector<T, A> & b)
{ 
    a.swap(b);
    b.clear(); // not important what you do with b
}

void fm(std::vector<T, A> & a, std::vector<T, A> & b)
{
    a = std::move(b);
}

The purpose of both functions fs and fm is to give a the state that b had initially. However, there is a hidden question: What happens if a.get_allocator() != b.get_allocator()? The answer is: It depends. Let's write AT = std::allocator_traits<A>.

• If AT::propagate_on_container_move_assignment is std::true_type, then fm reassigns the allocator of a with the value of b.get_allocator(), otherwise it does not, and a continues to use its original allocator. In that case, the data elements need to be swapped individually, since the storage of a and b is not compatible.

• If AT::propagate_on_container_swap is std::true_type, then fs swaps both data and allocators in the expected fashion.

• If AT::propagate_on_container_swap is std::false_type, then we need a dynamic check.

  • If a.get_allocator() == b.get_allocator(), then the two containers use compatible storage, and swapping proceeds in the usual fashion.
  • However, if a.get_allocator() != b.get_allocator(), the program has undefined behaviour (cf. [container.requirements.general/8].

The upshot is that swapping has become a non-trivial operation in C++11 as soon as your container starts supporting stateful allocators. That's a somewhat "advanced use case", but it's not entirely unlikely, since move optimizations usually only become interesting once your class manages a resource, and memory is one of the most popular resources.

I should like to provide the modern answer.

You shouldn’t really want to convert a date and time from a string at one GMT offset to a string at a different GMT offset and with in a different format. Rather in your program keep an instant (a point in time) as a proper date-time object. Only when you need to give string output, format your object into the desired string.

java.time

Parsing input

    DateTimeFormatter formatter = new DateTimeFormatterBuilder()
            .append(DateTimeFormatter.ISO_LOCAL_DATE)
            .appendLiteral(' ')
            .append(DateTimeFormatter.ISO_LOCAL_TIME)
            .toFormatter();

    String dateTimeString = "2011-10-06 03:35:05";
    Instant instant = LocalDateTime.parse(dateTimeString, formatter)
            .atOffset(ZoneOffset.UTC)
            .toInstant();

For most purposes Instant is a good choice for storing a point in time. If you needed to make it explicit that the date and time came from GMT, use an OffsetDateTime instead.

Converting, formatting and printing output

    ZoneId desiredZone = ZoneId.of("Pacific/Auckland");
    Locale desiredeLocale = Locale.forLanguageTag("en-NZ");
    DateTimeFormatter desiredFormatter = DateTimeFormatter.ofPattern(
            "dd MMM uuuu HH:mm:ss OOOO", desiredeLocale);

    ZonedDateTime desiredDateTime = instant.atZone(desiredZone);
    String result = desiredDateTime.format(desiredFormatter);
    System.out.println(result);

This printed:

06 Oct 2011 16:35:05 GMT+13:00

I specified time zone Pacific/Auckland rather than the offset you mentioned, +13:00. I understood that you wanted New Zealand time, and Pacific/Auckland better tells the reader this. The time zone also takes summer time (DST) into account so you don’t need to take this into account in your own code (for most purposes).

Since Oct is in English, it’s a good idea to give the formatter an explicit locale. GMT might be localized too, but I think that it just prints GMT in all locales.

OOOO in the format patterns string is one way of printing the offset, which may be a better idea than printing the time zone abbreviation you would get from z since time zone abbreviations are often ambiguous. If you want NZDT (for New Zealand Daylight Time), just put z there instead.

Your questions

I will answer your numbered questions in relation to the modern classes in java.time.

Is possible to:

1. Set the time on an object

No, the modern classes are immutable. You need to create an object that has the desired date and time from the outset (this has a number of advantages including thread safety).

2. (Possibly) Set the TimeZone of the initial time stamp

The atZone method that I use in the code returns a ZonedDateTime with the specified time zone. Other date-time classes have a similar method, sometimes called atZoneSameInstant or other names.

3. Format the time stamp with a new TimeZone

With java.time converting to a new time zone and formatting are two distinct steps as shown.

4. Return a string with new time zone time.

Yes, convert to the desired time zone as shown and format as shown.

I found that anytime I try to set the time like this:

calendar.setTime(new Date(1317816735000L));

the local machine's TimeZone is used. Why is that?

It’s not the way you think, which goes nicely to show just a couple of the (many) design problems with the old classes.

• A Date hasn’t got a time zone. Only when you print it, its toString method grabs your local time zone and uses it for rendering the string. This is true for new Date() too. This behaviour has confused many, many programmers over the last 25 years.
• A Calender has got a time zone. It doesn’t change when you do calendar.setTime(new Date(1317816735000L));.

An alternative to the many solutions already provided is making use of the glob **. When you use bash with the option globstar (shopt -s globstar) or you make use of zsh, you can just use the glob ** for this.

**/bar

does a recursive directory search for files named bar (potentially including the file bar in the current directory). Remark that this cannot be combined with other forms of globbing within the same path segment; in that case, the * operators revert to their usual effect.

Note that there is a subtle difference between zsh and bash here. While bash will traverse soft-links to directories, zsh will not. For this you have to use the glob ***/ in zsh.

forever might be of interest to you. It will run your .js-File 24/7 with logging options. Here are two snippets from the help text:

[Long Running Process] The forever process will continue to run outputting log messages to the console. ex. forever -o out.log -e err.log my-script.js

and

[Daemon] The forever process will run as a daemon which will make the target process start in the background. This is extremely useful for remote starting simple node.js scripts without using nohup. It is recommended to run start with -o -l, & -e. ex. forever start -l forever.log -o out.log -e err.log my-daemon.js forever stop my-daemon.js

If you set up a JBoss server using the Eclipse WebTools, you can simply start the server in debug mode (debug button in the servers view). This will allow you to set breakpoints in the application that is running inside the JBoss.

Sometimes what you're seeing is a box shadow, not a text underline.

Try this (using whatever CSS selectors are appropriate for you):

a:hover, a:visited, a:link, a:active {

    text-decoration: none!important;

    -webkit-box-shadow: none!important;
    box-shadow: none!important;
}

For the time being I am going a different route than I previous stated. I changed the way I am formatting the data to:

  &A2168=1&A1837=5&A8472=1&A1987=2

On the server side I am using getParameterNames() to place all the keys into an Enumerator and then iterating over the Enumerator and placing the keys and values into a HashMap. It looks something like this:

Enumeration keys = request.getParameterNames(); 
HashMap map = new HashMap(); 
String key = null; 
while(keys.hasMoreElements()){ 
      key = keys.nextElement().toString(); 
      map.put(key, request.getParameter(key)); 
}

Just right click on the file or on the project and click Refresh. The error will vanish. I also faced the same issue and it worked for me.

Similarly in Java, you can create a S4 class in R that encapsulates your information:

setClass(Class="Person",
         representation(
            height="numeric",
            age="numeric"
          )
)

Then your function can return an instance of this class:

myFunction = function(age=28, height=176){
  return(new("Person",
          age=age,
          height=height))
}

and you can access your information:

aPerson = myFunction()

aPerson@age
aPerson@height

Padding on/off. Determines the effective size of your input.

VALID: No padding. Convolution etc. ops are only performed at locations that are "valid", i.e. not too close to the borders of your tensor.
With a kernel of 3x3 and image of 10x10, you would be performing convolution on the 8x8 area inside the borders.

SAME: Padding is provided. Whenever your operation references a neighborhood (no matter how big), zero values are provided when that neighborhood extends outside the original tensor to allow that operation to work also on border values.
With a kernel of 3x3 and image of 10x10, you would be performing convolution on the full 10x10 area.

You probably need more blur and a little less spread.

box-shadow: -10px 0px 10px 1px #aaaaaa;

Try messing around with the box shadow generator here http://css3generator.com/ until you get your desired effect.

for me, shift + enter did the trick.

This error you are receiving :

SQLSTATE[HY093]: Invalid parameter number: parameter was not defined

is because the number of elements in $values & $matches is not the same or $matches contains more than 1 element.

If $matches contains more than 1 element, than the insert will fail, because there is only 1 column name referenced in the query(hash)

If $values & $matches do not contain the same number of elements then the insert will also fail, due to the query expecting x params but it is receiving y data $matches.

I believe you will also need to ensure the column hash has a unique index on it as well.

Try the code here:

<?php

/*** mysql hostname ***/
$hostname = 'localhost';

/*** mysql username ***/
$username = 'root';

/*** mysql password ***/
$password = '';

try {
    $dbh = new PDO("mysql:host=$hostname;dbname=test", $username, $password);
    /*** echo a message saying we have connected ***/
    echo 'Connected to database';
    }
catch(PDOException $e)
    {
    echo $e->getMessage();
    }


$matches = array('1');
$count = count($matches);
for($i = 0; $i < $count; ++$i) {
    $values[] = '?';
}

// INSERT INTO DATABASE
$sql = "INSERT INTO hashes (hash) VALUES (" . implode(', ', $values) . ") ON DUPLICATE KEY UPDATE hash='hash'";
$stmt = $dbh->prepare($sql);
$data = $stmt->execute($matches);

//Error reporting if something went wrong...
var_dump($dbh->errorInfo());

?>

You will need to adapt it a little.

Table structure I used is here:

CREATE TABLE IF NOT EXISTS `hashes` (
  `hashid` int(11) NOT NULL AUTO_INCREMENT,
  `hash` varchar(250) NOT NULL,
  PRIMARY KEY (`hashid`),
  UNIQUE KEY `hash1` (`hash`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Code was run on my XAMPP Server which is using PHP 5.3.8 with MySQL 5.5.16.

I hope this helps.

Talking about .hpp extension, I find it useful when people are supposed to know that this header file contains C++ an not C, like using namespaces or template etc, by the moment they see the files, so they won't try to feed it to a C compiler! And I also like to name header files which contain not only declarations but implementations as well, as .hpp files. like header files including template classes. Although that's just my opinion and of course it's not supposed to be right! :)

in shell command:

echo "bar embarassment" | sed "s/\bbar\b/no bar/g" 

or:

There are 2 differences:

2 methods creating a user and granting some privileges to him

create user userName identified by password;
grant connect to userName;

and

grant connect to userName identified by password;

do exactly the same. It creates a user and grants him the connect role.

different outcome

resource is a role in oracle, which gives you the right to create objects (tables, procedures, some more but no views!). ALL PRIVILEGES grants a lot more of system privileges.

To grant a user all privileges run you first snippet or

grant all privileges to userName identified by password;

You can execute following command in your terminal :

export PATH="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin:$PATH"

And this replaces the java old with new one.

I encountered the same error, with the below code.

    return this.state.employees.map((employee) => {
      <option value={employee.id}>
        {employee.name}
      </option>
    });

Above issue got resolved, when I changed curly braces to parenthesis, as indicated in the below modified code snippet.

      return this.state.employees.map((employee) => (
          <option value={employee.id}>
            {employee.name}
          </option>
        ));

Set the CSS position: relative; on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:

position: absolute;
bottom: 0;
right: 0;

If you need to space the text farther away from the edge, you could change 0 to 2px or similar.

Note: This answers the question as written, but not the problem as stated. Adding it here, since people will be searching for it

Semicolon is also used before WITH in recursive CTE statements:

;WITH Numbers AS
(
    SELECT n = 1
    UNION ALL
    SELECT n + 1
    FROM Numbers
    WHERE n+1 <= 10
)
SELECT n
FROM Numbers

This query will generate a CTE called Numbers that consists of integers [1..10]. It is done by creating a table with the value 1 only, and then recursing until you reach 10.

{{ form_widget(form.content, { 'attr': {'class': 'tinyMCE', 'data-theme': 'advanced'} })  }}

$("form#submit input").on('keypress',function(event) {
  event.preventDefault();
  if (event.which === 13) {
    $('button.submit').trigger('click');
  }
});

You can't include server side PHP in your client side javascript, you will have to port it over to javascript. If you wish, you can use php.js, which ports all PHP functions over to javascript. You can also create a new php file that returns the results of calling your PHP function, and then call that file using AJAX to get the results.

I had similar issue, my code was:

function RadioInput(props) {
    return (
    <div className="form-check form-check-inline">
        <input className="form-check-input" type="radio" name="inlineRadioOptions" id={props.id} onClick={props.onClick} value={props.label}></input>
        <label className="form-check-label" htmlFor={props.id}>{props.label}</label>
    </div>
    );
  }
class ScheduleType extends React.Component
{
    renderRadioInput(id,label)
    {
        id = "inlineRadio"+id;
        return(
            <RadioInput
                id = {id}
                label = {label}
                onClick = {this.props.onClick}
            />
        );

    }

Where it should be

onClick = {() => this.props.onClick()}

in RenderRadioInput

It fixed the issue for me.

As you've noted HttpServletRequest does not have a setParameter method. This is deliberate, since the class represents the request as it came from the client, and modifying the parameter would not represent that.

One solution is to use the HttpServletRequestWrapper class, which allows you to wrap one request with another. You can subclass that, and override the getParameter method to return your sanitized value. You can then pass that wrapped request to chain.doFilter instead of the original request.

It's a bit ugly, but that's what the servlet API says you should do. If you try to pass anything else to doFilter, some servlet containers will complain that you have violated the spec, and will refuse to handle it.

A more elegant solution is more work - modify the original servlet/JSP that processes the parameter, so that it expects a request attribute instead of a parameter. The filter examines the parameter, sanitizes it, and sets the attribute (using request.setAttribute) with the sanitized value. No subclassing, no spoofing, but does require you to modify other parts of your application.

I had this error message when trying "hello world" like things with Qt. The problems went away by correctly running the qt moc (meta object compiler) and compiling+including these moc-generated files correctly.

This is what exactly worked for me:

1. Make sure no other MySQL process is running.To check this do the following:

    a.From the terminal, run this command:
          lsof -i:3306 
      If any PID is returned, kill it using kill -9 PID
    b. Go To System Preferences > MySQL > check if any MySQL instances 
       are running, stop them.
   

2. Start MySQL with the command:

   sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
   

3. The password for every user is stored in the mysql.user table under columns User and authentication_string respectively. We can update the table as:

   UPDATE mysql.user SET authentication_string='your_password' where User='root'
   

No, CASE is a function, and can only return a single value. I think you are going to have to duplicate your CASE logic.

The other option would be to wrap the whole query with an IF and have two separate queries to return results. Without seeing the rest of the query, it's hard to say if that would work for you.

Here is my option to Edit the project file without the need to Unload the project:

1. Open Solution Explorer and switch to folder view:

2. Navigate to the Project which you want to edit inside the Solution folders and right-click on it.

3. Choose Open from the Context Menu.

That is it!

You will see the *.csproj file opened inside Visual Studio Editor.
After you can switch back to a Solution/Project view (see step 1).

Depending on your rights, you need sudo at beginning.

You can use ESCAPE:

WHERE columnName LIKE '%\%%' ESCAPE '\'

I ran into the same issue with CLion 1.2.1 (at the time of writing this answer) after updating Windows 10. It was working fine before I had updated my OS. My OS is installed in C:\ drive and CLion 1.2.1 and Cygwin (64-bit) are installed in D:\ drive.

The issue seems to be with CMake. I am using Cygwin. Below is the short answer with steps I used to fix the issue.

SHORT ANSWER (should be similar for MinGW too but I haven't tried it):

1. Install Cygwin with GCC, G++, GDB and CMake (the required versions)
2. Add full path to Cygwin 'bin' directory to Windows Environment variables
3. Restart CLion and check 'Settings' -> 'Build, Execution, Deployment' to make sure CLion has picked up the right versions of Cygwin, make and gdb
4. Check the project configuration ('Run' -> 'Edit configuration') to make sure your project name appears there and you can select options in 'Target', 'Configuration' and 'Executable' fields.
5. Build and then Run
6. Enjoy

LONG ANSWER:

Below are the detailed steps that solved this issue for me:

1. Uninstall/delete the previous version of Cygwin (MinGW in your case)

2. Make sure that CLion is up-to-date

3. Run Cygwin setup (x64 for my 64-bit OS)

4. Install at least the following packages for Cygwin: gcc g++ make Cmake gdb Make sure you are installing the correct versions of the above packages that CLion requires. You can find the required version numbers at CLion's Quick Start section (I cannot post more than 2 links until I have more reputation points).

5. Next, you need to add Cygwin (or MinGW) to your Windows Environment Variable called 'Path'. You can Google how to find environment variables for your version of Windows

[On Win 10, right-click on 'This PC' and select Properties -> Advanced system settings -> Environment variables... -> under 'System Variables' -> find 'Path' -> click 'Edit']

6. Add the 'bin' folder to the Path variable. For Cygwin, I added: D:\cygwin64\bin

7. Start CLion and go to 'Settings' either from the 'Welcome Screen' or from File -> Settings

8. Select 'Build, Execution, Deployment' and then click on 'Toolchains'

9. Your 'Environment' should show the correct path to your Cygwin installation directory (or MinGW)

10. For 'CMake executable', select 'Use bundled CMake x.x.x' (3.3.2 in my case at the time of writing this answer)

11. 'Debugger' shown to me says 'Cygwin GDB GNU gdb (GDB) 7.8' [too many gdb's in that line ;-)]

12. Below that it should show a checkmark for all the categories and should also show the correct path to 'make', 'C compiler' and 'C++ compiler'

See screenshot: Check all paths to the compiler, make and gdb

13. Now go to 'Run' -> 'Edit configuration'. You should see your project name in the left-side panel and the configurations on the right side

See screenshot: Check the configuration to run the project

14. There should be no errors in the console window. You will see that the 'Run' -> 'Build' option is now active

15. Build your project and then run the project. You should see the output in the terminal window

Hope this helps! Good luck and enjoy CLion.

You need to :

1. Delete the state: Delete the migrations folder in your project; And
2. Delete the __MigrationHistory table in your database (may be under system tables); Then

3. Run the following command in the Package Manager Console:

   Enable-Migrations -EnableAutomaticMigrations -Force
   

   Use with or without -EnableAutomaticMigrations

4. And finally, you can run:

   Add-Migration Initial

The solution solve also the case where the client stays with the browser open for days, the client checks for updates on intervals and reload if newer version deployd.

The solution is a bit tricky but works like a charm:

• use the fact that ng cli -- prod produces hashed files with one of them called main.[hash].js
• create a version.json file that contains that hash
• create an angular service VersionCheckService that checks version.json and reload if needed.
• Note that a js script running after deployment creates for you both version.json and replace the hash in angular service, so no manual work needed, but running post-build.js

Since Henrik Peinar solution was for angular 4, there were minor changes, I place also the fixed scripts here:

VersionCheckService :

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable()
export class VersionCheckService {
    // this will be replaced by actual hash post-build.js
    private currentHash = '{{POST_BUILD_ENTERS_HASH_HERE}}';

    constructor(private http: HttpClient) {}

    /**
     * Checks in every set frequency the version of frontend application
     * @param url
     * @param {number} frequency - in milliseconds, defaults to 30 minutes
     */
    public initVersionCheck(url, frequency = 1000 * 60 * 30) {
        //check for first time
        this.checkVersion(url); 

        setInterval(() => {
            this.checkVersion(url);
        }, frequency);
    }

    /**
     * Will do the call and check if the hash has changed or not
     * @param url
     */
    private checkVersion(url) {
        // timestamp these requests to invalidate caches
        this.http.get(url + '?t=' + new Date().getTime())
            .subscribe(
                (response: any) => {
                    const hash = response.hash;
                    const hashChanged = this.hasHashChanged(this.currentHash, hash);

                    // If new version, do something
                    if (hashChanged) {
                        // ENTER YOUR CODE TO DO SOMETHING UPON VERSION CHANGE
                        // for an example: location.reload();
                        // or to ensure cdn miss: window.location.replace(window.location.href + '?rand=' + Math.random());
                    }
                    // store the new hash so we wouldn't trigger versionChange again
                    // only necessary in case you did not force refresh
                    this.currentHash = hash;
                },
                (err) => {
                    console.error(err, 'Could not get version');
                }
            );
    }

    /**
     * Checks if hash has changed.
     * This file has the JS hash, if it is a different one than in the version.json
     * we are dealing with version change
     * @param currentHash
     * @param newHash
     * @returns {boolean}
     */
    private hasHashChanged(currentHash, newHash) {
        if (!currentHash || currentHash === '{{POST_BUILD_ENTERS_HASH_HERE}}') {
            return false;
        }

        return currentHash !== newHash;
    }
}

change to main AppComponent:

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
    constructor(private versionCheckService: VersionCheckService) {

    }

    ngOnInit() {
        console.log('AppComponent.ngOnInit() environment.versionCheckUrl=' + environment.versionCheckUrl);
        if (environment.versionCheckUrl) {
            this.versionCheckService.initVersionCheck(environment.versionCheckUrl);
        }
    }

}

The post-build script that makes the magic, post-build.js:

const path = require('path');
const fs = require('fs');
const util = require('util');

// get application version from package.json
const appVersion = require('../package.json').version;

// promisify core API's
const readDir = util.promisify(fs.readdir);
const writeFile = util.promisify(fs.writeFile);
const readFile = util.promisify(fs.readFile);

console.log('\nRunning post-build tasks');

// our version.json will be in the dist folder
const versionFilePath = path.join(__dirname + '/../dist/version.json');

let mainHash = '';
let mainBundleFile = '';

// RegExp to find main.bundle.js, even if it doesn't include a hash in it's name (dev build)
let mainBundleRegexp = /^main.?([a-z0-9]*)?.js$/;

// read the dist folder files and find the one we're looking for
readDir(path.join(__dirname, '../dist/'))
  .then(files => {
    mainBundleFile = files.find(f => mainBundleRegexp.test(f));

    if (mainBundleFile) {
      let matchHash = mainBundleFile.match(mainBundleRegexp);

      // if it has a hash in it's name, mark it down
      if (matchHash.length > 1 && !!matchHash[1]) {
        mainHash = matchHash[1];
      }
    }

    console.log(`Writing version and hash to ${versionFilePath}`);

    // write current version and hash into the version.json file
    const src = `{"version": "${appVersion}", "hash": "${mainHash}"}`;
    return writeFile(versionFilePath, src);
  }).then(() => {
    // main bundle file not found, dev build?
    if (!mainBundleFile) {
      return;
    }

    console.log(`Replacing hash in the ${mainBundleFile}`);

    // replace hash placeholder in our main.js file so the code knows it's current hash
    const mainFilepath = path.join(__dirname, '../dist/', mainBundleFile);
    return readFile(mainFilepath, 'utf8')
      .then(mainFileData => {
        const replacedFile = mainFileData.replace('{{POST_BUILD_ENTERS_HASH_HERE}}', mainHash);
        return writeFile(mainFilepath, replacedFile);
      });
  }).catch(err => {
    console.log('Error with post build:', err);
  });

simply place the script in (new) build folder run the script using node ./build/post-build.js after building dist folder using ng build --prod

The compareTo method is described as follows:

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Let's say we would like to compare Jedis by their age:

class Jedi implements Comparable<Jedi> {

    private final String name;
    private final int age;
        //...
}

Then if our Jedi is older than the provided one, you must return a positive, if they are the same age, you return 0, and if our Jedi is younger you return a negative.

public int compareTo(Jedi jedi){
    return this.age > jedi.age ? 1 : this.age < jedi.age ? -1 : 0;
}

By implementing the compareTo method (coming from the Comparable interface) your are defining what is called a natural order. All sorting methods in JDK will use this ordering by default.

There are ocassions in which you may want to base your comparision in other objects, and not on a primitive type. For instance, copare Jedis based on their names. In this case, if the objects being compared already implement Comparable then you can do the comparison using its compareTo method.

public int compareTo(Jedi jedi){
    return this.name.compareTo(jedi.getName());
}

It would be simpler in this case.

Now, if you inted to use both name and age as the comparison criteria then you have to decide your oder of comparison, what has precedence. For instance, if two Jedis are named the same, then you can use their age to decide which goes first and which goes second.

public int compareTo(Jedi jedi){
    int result = this.name.compareTo(jedi.getName());
    if(result == 0){
        result = this.age > jedi.age ? 1 : this.age < jedi.age ? -1 : 0;
    }
    return result;
}

If you had an array of Jedis

Jedi[] jediAcademy = {new Jedi("Obiwan",80), new Jedi("Anakin", 30), ..}

All you have to do is to ask to the class java.util.Arrays to use its sort method.

Arrays.sort(jediAcademy);

This Arrays.sort method will use your compareTo method to sort the objects one by one.

You may also want to check to see whether you're linking against the dynamic or static C runtime library. If your DLL files are linking against the static C runtime library, then the DLL files have separate heaps.

Hence, if you were to create an object in one DLL and try to free it in another DLL, you would get the same message you're seeing above. This problem is referenced in another Stack Overflow question, Freeing memory allocated in a different DLL.

In my case simply restarting the WiFi router helped.

I found that I could access the checkbox directly using Worksheets("SheetName").CB_Checkboxname.value directly without relating to additional objects.

If the list is in random order, you can just take the first 50.

Otherwise, use

import random
random.sample(the_list, 50)

random.sample help text:

sample(self, population, k) method of random.Random instance
    Chooses k unique random elements from a population sequence.

    Returns a new list containing elements from the population while
    leaving the original population unchanged.  The resulting list is
    in selection order so that all sub-slices will also be valid random
    samples.  This allows raffle winners (the sample) to be partitioned
    into grand prize and second place winners (the subslices).

    Members of the population need not be hashable or unique.  If the
    population contains repeats, then each occurrence is a possible
    selection in the sample.

    To choose a sample in a range of integers, use xrange as an argument.
    This is especially fast and space efficient for sampling from a
    large population:   sample(xrange(10000000), 60)

IE10 does not support DX filters as IE9 and earlier have done, nor does it support a prefixed version of the greyscale filter.

However, you can use an SVG overlay in IE10 to accomplish the greyscaling. Example:

img.grayscale:hover {
    filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'1 0 0 0 0, 0 1 0 0 0, 0 0 1 0 0, 0 0 0 1 0\'/></filter></svg>#grayscale");
}

svg {
    background:url(http://4.bp.blogspot.com/-IzPWLqY4gJ0/T01CPzNb1KI/AAAAAAAACgA/_8uyj68QhFE/s400/a2cf7051-5952-4b39-aca3-4481976cb242.jpg);
}

(from: http://www.karlhorky.com/2012/06/cross-browser-image-grayscale-with-css.html)

Simplified JSFiddle: http://jsfiddle.net/KatieK/qhU7d/2/

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

If you are looking globabally setup timezone in whole project then you can setup it CI application/config.php file

$config['time_reference'] = 'Asia/Dubai';

You can get all keys in the Request.Form and then compare and get your desired values.

Your method body will look like this: -

List<int> listValues = new List<int>();
foreach (string key in Request.Form.AllKeys)
{
    if (key.StartsWith("List"))
    {
        listValues.Add(Convert.ToInt32(Request.Form[key]));
    }
}

Also, could be simple as:

if( typeof foo == "function" )
    foo();

I have used following for the same:

<script type="application/javascript">
    $('input[type="file"]').change(function(e){
        var fileName = e.target.files[0].name;
        $('.custom-file-label').html(fileName);
    });
</script>

Array.prototype.unique = function () {
  return [...new Set(this)]
}

then we can write:

const arr = [1, 5, 2, 2, 2, 3, 4, 3, 2, 1, 5]
const uniqueArr = arr.unique()

Tomcat 8 : After many searches this is only working code: in server.xml

<!-- Set /apple as default path -->
    <Host name="localhost"  appBase="webapps"
         unpackWARs="true" autoDeploy="true">
     <Context path="" docBase="apple">
         <!-- Default set of monitored resources -->
         <WatchedResource>WEB-INF/web.xml</WatchedResource>
     </Context>

Restart Tomcat, make sure when you access 127.0.0.1:8080, it will display the content in 127.0.0.1:8080/apple

My project was java web application witch created by netbeans ,I set context path in project configuration, no other thing, even I put apple.war in webapps folder.

I got this error when I was using the app icon image which was resized to 120x120 from 180x180 sized icon using the preview app on MAC. The error is gone When I removed the 120x120 icon from the project. Resizing icons can mess-up with the format required by Apple.

Relying on the raised exception is not the fastest, readable nor reliable solution.
I'd do the following :

my_string.should =~ /^[0-9]+$/

Well, you could erase() the first character too (note that erase() modifies the string):

m_VirtualHostName.erase(0, 1);
m_VirtualHostName.erase(m_VirtualHostName.size() - 1);

But in this case, a simpler way is to take a substring:

m_VirtualHostName = m_VirtualHostName.substr(1, m_VirtualHostName.size() - 2);

Be careful to validate that the string actually has at least two characters in it first...

mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given

This means that the first parameter you passed is a boolean (true or false).

The first parameter is $result, and it is false because there is a syntax error in the query.

" ... WHERE PartNumber = $partid';"

You should never directly include a request variable in a SQL query, else the users are able to inject SQL in your queries. (See SQL injection.)

You should escape the variable:

" ... WHERE PartNumber = '" . mysqli_escape_string($conn,$partid) . "';"

Or better, use Prepared Statements.

Another possibility is that you have saved the apk file into application PRIVATE folder and then try to install (by starting an intent from your code). in this case, when you start intent, you get error parsing package. In this case, the raised error is about permission issues. The point is saving the file into private folders is not a good practice, however if you really want to do that, you should write file in MODE_WORL_READABLE when you download it. Please consider that MODE_WORLD_READABLE is deprecated and this solution is not the best as it has some security issues. The best is to save your file in an external storage.

Sending your activity context to other classes could cause memoryleaks because holding that context alive is the reason that the GC can't dispose the object

After doing extensive research on all the options around "enumerations" in Scala, I posted a much more complete overview of this domain on another StackOverflow thread. It includes a solution to the "sealed trait + case object" pattern where I have solved the JVM class/object initialization ordering problem.

Check this: http://jsfiddle.net/h7kRt/1/,

you should change in jsfiddle on top-left to No-wrap in <head>

Your code looks good and it will work inside a normal page. In jsfiddle your function was being defined inside a load handler and thus is in a different scope. By changing to No-wrap you have it in the global scope and can use it as you wanted.

It's a lambda expression.

It means that, from the listOfCars, arg0 is one of the items of that list. With that item he is going to do, hence the ->, whatever is inside of the brackets.

In this example, he's going to return a list of cars that fit the condition

Car.SEDAN == ((Car)arg0).getStyle();

The only problem I see with the first method is if you are planning to add more constructors. Then you will be repeating code and maintainability would suffer.

You have to create a new template for item selection like this.

<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="ListBoxItem">
            <Border
                BorderThickness="{TemplateBinding Border.BorderThickness}"
                Padding="{TemplateBinding Control.Padding}"
                BorderBrush="{TemplateBinding Border.BorderBrush}"
                Background="{TemplateBinding Panel.Background}"
                SnapsToDevicePixels="True">
                <ContentPresenter
                    Content="{TemplateBinding ContentControl.Content}"
                    ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"
                    HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
                    VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
                    SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" />
            </Border>
        </ControlTemplate>
    </Setter.Value>
</Setter>

ConcurrentHashMap is optimized for concurrent access.

Accesses don't lock the whole map but use a finer grained strategy, which improves scalability. There are also functional enhanvements specifically for concurrent access, e.g. concurrent iterators.

Actually you have a code compiled targeting a higher JDK (JDK 1.8 in your case) but at runtime you are supplying a lower JRE(JRE 7 or below).

you can fix this problem by adding target parameter while compilation
e.g. if your runtime target is 1.7, you should use 1.7 or below

javac -target 1.7 *.java

if you are using eclipse, you can sent this parameter at Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" = choose your runtime jre version or lower.

So far, all the answers use the external program date.

Since Bash 4.2, printf has a new modifier %(dateformat)T that, when used with argument -1 outputs the current date with format given by dateformat, handled by strftime(3) (man 3 strftime for informations about the formats).

So, for a pure Bash solution:

printf '%(%s)T\n' -1

or if you need to store the result in a variable var:

printf -v var '%(%s)T' -1

No external programs and no subshells!

Since Bash 4.3, it's even possible to not specify the -1:

printf -v var '%(%s)T'

(but it might be wiser to always give the argument -1 nonetheless).

If you use -2 as argument instead of -1, Bash will use the time the shell was started instead of the current date. This can be used to compute elapsed times

$ printf -v beg '%(%s)T\n' -2
$ printf -v now '%(%s)T\n' -1
$ echo beg=$beg now=$now elapsed=$((now-beg))
beg=1583949610 now=1583953032 elapsed=3422

If you are using Oracle, this code can help you:

select 
TRUNC(sysdate, 'YEAR') Start_of_the_year,
TRUNC(sysdate, 'MONTH') Start_of_the_month,
TRUNC(sysdate, 'DAY') start_of_the_week,
TRUNC(sysdate+365, 'YEAR')-1 End_of_the_year,
TRUNC(sysdate+30, 'MONTH')-1 End_of_the_month,
TRUNC(sysdate+6, 'DAY')-1 end_of_the_week
from dual;


select 
TRUNC(sysdate, 'YEAR') Start_of_the_year,
TRUNC(sysdate+365, 'YEAR')-1 End_of_the_year,
TRUNC(sysdate, 'MONTH') Start_of_the_month,
TRUNC(sysdate+30, 'MONTH')-1 End_of_the_month,
TRUNC(sysdate, 'DAY')+1 start_of_the_week,  -- starting Monday
TRUNC(sysdate+6, 'DAY') end_of_the_week     -- finish Sunday
from dual;

CSS was designed to affect presentation, not behaviour.

You could use some JavaScript.

document.links[0].onclick = function(event) {
   event.preventDefault();
};

This worked for me:

    file = open('docs/my_messy_doc.pdf', 'rb')

ArrayList is newer and 20-30% faster.

If you don't need something explitly apparent in Vector, use ArrayList

You might be an admin doing a one-off push directly into refs/changes/<change_number>.

For example, once a commit without Change-Id landed into Subversion, you pull it out of Subversion using git-svn, and you'd like to archive it as a Gerrit patchset into a Gerrit change.

If so, you can go to project settings page (http://[installation-path]/#/admin/projects/[project-id]) and temporarily change "Require Change-Id in commit message" value to False.

Don't forget to afterwards change it back to Inherit or True!

Yes. In the javascript code:

window.location.href = "http://new.website.com/that/you/want_to_go_to.html";

This way worked for me when adding random data to MySql table using a python script.
First install the following packages using the below commands

pip install mysql-connector-python<br>
pip install random

import mysql.connector
import random

from datetime import date


start_dt = date.today().replace(day=1, month=1).toordinal()
end_dt = date.today().toordinal()

mydb = mysql.connector.connect(
    host="localhost",
    user="root",
    password="root",
    database="your_db_name"
)

mycursor = mydb.cursor()

sql_insertion = "INSERT INTO customer (name,email,address,dateJoined) VALUES (%s, %s,%s, %s)"
#insert 10 records(rows)
for x in range(1,11):
    #generate a random date
    random_day = date.fromordinal(random.randint(start_dt, end_dt))
    value = ("customer" + str(x),"customer_email" + str(x),"customer_address" + str(x),random_day)
    mycursor.execute(sql_insertion , value)

mydb.commit()

print("customer records inserted!")

Following is a sample output of the insertion

cid       |  name      |  email           |    address        |  dateJoined  |

1         | customer1  |  customer_email1 | customer_address1 |  2020-11-15  |
2         | customer2  |  customer_email2 | customer_address2 |  2020-10-11  |
3         | customer3  |  customer_email3 | customer_address3 |  2020-11-17  |
4         | customer4  |  customer_email4 | customer_address4 |  2020-09-20  |
5         | customer5  |  customer_email5 | customer_address5 |  2020-02-18  |
6         | customer6  |  customer_email6 | customer_address6 |  2020-01-11  |
7         | customer7  |  customer_email7 | customer_address7 |  2020-05-30  |
8         | customer8  |  customer_email8 | customer_address8 |  2020-04-22  |
9         | customer9  |  customer_email9 | customer_address9 |  2020-01-05  |
10        | customer10 |  customer_email10| customer_address10|  2020-11-12  |

There are several to pick from in the gallery but the one I'm using, which offers considerable level of configurability still remaining unobtrusive to the rest of the settings is Beautify by Michele Melluso. It works on both CSS and SCSS and lets you indent 3 spaces keeping the rest of the code at 2 spaces, which is nice.

You can snatch it from GitHub and adapt it yourself, should you feel like it too.

Increase your CSS Specificity

Example:

.parent-class .flex-control-thumbs li {
  width: auto;
  float: none;
}

Demo:

.sample-class {
  height: 50px;
  width: 50px;
  background: red;
}

.inner-page .sample-class {
  background: green;
}

<div>
  <div class="sample-class"></div>
</div>

<div class="inner-page">
  <div class="sample-class"></div>
</div>

This should display the image inline:

.content-dir-item img.mail {
    display: inline-block;
    *display: inline; /* for older IE */
    *zoom: 1; /* for older IE */
}

You could do it in either of this ways , triggering an onclick on a form button like this,

<form id="myform" name="myform" method="post" action="demo2.jsp">
    <input type="text"  name="usnername" />
    <input type="text" name="password"/>        
    <input type="button" value="go" onclick="submitForm" />
</form>

And using javascript,

        function submitForm() {                
            document.forms[0].submit();
            return true;
        }

or you could also try Ajax to post your page

here is the link jQueryAjax

And also nice startup examples using Ajax and here

Hope this helps !!

I don't know if something like that already exists. It would be easy to write your own with time, datetime and/or calendar modules, see http://docs.python.org/library/time.html

The only concern for a python solution is that your job needs to be always running and possibly be automatically "resurrected" after a reboot, something for which you do need to rely on system dependent solutions.

If the array is statically allocated, use sizeof(array) / sizeof(array[0])

If it's dynamically allocated, though, unfortunately you're out of luck as this trick will always return sizeof(pointer_type)/sizeof(array[0]) (which will be 4 on a 32 bit system with char*s) You could either a) keep a #define (or const) constant, or b) keep a variable, however.

An empty static class is appropriate. Consider using several classes, so that you end up with good groups of related constants, and not one giant Globals.cs file.

Additionally, for some int constants, consider the notation:

[Flags]
enum Foo
{
}

As this allows for treating the values like flags.

Maybe you can simply

$ sudo bash -c "echo vm.overcommit_memory=1 >> /etc/sysctl.conf"
$ sudo sysctl -p

It works for my case.

Reference: https://github.com/openai/gym/issues/110#issuecomment-220672405

Another short solution:

from datetime import date

def diff_dates(date1, date2):
    return abs(date2-date1).days

def main():
    d1 = date(2013,1,1)
    d2 = date(2013,9,13)
    result1 = diff_dates(d2, d1)
    print '{} days between {} and {}'.format(result1, d1, d2)
    print ("Happy programmer's day!")

main()

It looks like the object file was compiled on a 64-bit toolchain, and you're using a 32-bit toolchain. Have you tried recompiling the object file in 32-bit mode?

If you are using foreignkey then you have to use "on_delete=models.CASCADE" as it will eliminate the complexity developed after deleting the original element from the parent table. As simple as that.

categorie = models.ForeignKey('Categorie', on_delete=models.CASCADE)

If the main problem is the loss of precision when converting from a float to a string, one possible way to go is to convert the floats to the decimalS: http://docs.python.org/library/decimal.html.

In python 2.7 and higher you can directly convert a float to a decimal object.

I changed a hard disk, installed Windows. When tried to upload files received this command window.

I pressed "y", then Ctrl + C. Opened putty.exe, added an old key ther returned to git and pushed files.

The top answer suggests adding #!/bin/bash line to the first line of the sub-script being called. But even if you add the shebang, it is much faster^* to run a script in a sub-shell and capture the output:

$(source SCRIPT_NAME)

This works when you want to keep running the same interpreter (e.g. from bash to another bash script) and ensures that the shebang line of the sub-script is not executed.

For example:

#!/bin/bash
SUB_SCRIPT=$(mktemp)
echo "#!/bin/bash" > $SUB_SCRIPT
echo 'echo $1' >> $SUB_SCRIPT
chmod +x $SUB_SCRIPT
if [[ $1 == "--source" ]]; then
  for X in $(seq 100); do
    MODE=$(source $SUB_SCRIPT "source on")
  done
else
  for X in $(seq 100); do
    MODE=$($SUB_SCRIPT "source off")
  done
fi
echo $MODE
rm $SUB_SCRIPT

Output:

~ ??? time ./test.sh
source off
./test.sh  0.15s user 0.16s system 87% cpu 0.360 total

~ ??? time ./test.sh --source
source on
./test.sh --source  0.05s user 0.06s system 95% cpu 0.114 total

^* For example when virus or security tools are running on a device it might take an extra 100ms to exec a new process.

There are a few problems here.

1: onBlur expects a callback, and you are calling renderPasswordConfirmError and using the return value, which is null.

2: you need a place to render the error.

3: you need a flag to track "and I validating", which you would set to true on blur. You can set this to false on focus if you want, depending on your desired behavior.

handleBlur: function () {
  this.setState({validating: true});
},
render: function () {
  return <div>
    ...
    <input
        type="password"
        placeholder="Password (confirm)"
        valueLink={this.linkState('password2')}
        onBlur={this.handleBlur}
     />
    ...
    {this.renderPasswordConfirmError()}
  </div>
},
renderPasswordConfirmError: function() {
  if (this.state.validating && this.state.password !== this.state.password2) {
    return (
      <div>
        <label className="error">Please enter the same password again.</label>
      </div>
    );
  }  
  return null;
},

I had the same problem and when I checked the properties of the file on file explorer, it shows me the next message:

"Security: This file came from another computer and might be blocked to help protect this computer"

You click on the "Unblock" button and... you can access to the file from R without any problem, just using read.csv() function and from the directory specified as your working directory, even if is not the same as the file’s directory you are accessing to.

BackgroundTint works as color filter.

FEFBDE as tint

37AEE4 as background

Try seeing the difference by comment tint/background and check the output when both are set.

The getContentResolver()method is also used when you query a Contact, using a Cursor object. I have used getContentResolver() to query the Android phone Contacts app, looking for contact info from a person's phone number, to include in my app. The different elements in a query (as shown below) represent what kind of contact details you want, and if they should be ordered, etc. Here is another example.

From the Content Provider Basics page from Android docs.

// Queries the user dictionary and returns results
mCursor = getContentResolver().query(
    UserDictionary.Words.CONTENT_URI,   // The content URI of the words table
    mProjection,                        // The columns to return for each row
    mSelectionClause                    // Selection criteria
    mSelectionArgs,                     // Selection criteria
    mSortOrder);                        // The sort order for the returned rows

driver = webdriver.Firefox(...)  # Or Chrome(), or Ie(), or Opera()

username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")

username.send_keys("YourUsername")
password.send_keys("Pa55worD")

driver.find_element_by_name("submit").click()

Notes to your code:

• find_element_by_name('Username'): Username capitalized doesn't match anything.
• Select() is used to act on a Select Element (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select)

• First, str in Python is represented in Unicode.
• Second, UTF-8 is an encoding standard to encode Unicode string to bytes. There are many encoding standards out there (e.g. UTF-16, ASCII, SHIFT-JIS, etc.).

When the client sends data to your server and they are using UTF-8, they are sending a bunch of bytes not str.

You received a str because the "library" or "framework" that you are using, has implicitly converted some random bytes to str.

Under the hood, there is just a bunch of bytes. You just need ask the "library" to give you the request content in bytes and you will handle the decoding yourself (if library can't give you then it is trying to do black magic then you shouldn't use it).

• Decode UTF-8 encoded bytes to str: bs.decode('utf-8')
• Encode str to UTF-8 bytes: s.encode('utf-8')

Like this:

numrows = len(input)    # 3 rows in your example
numcols = len(input[0]) # 2 columns in your example

Assuming that all the sublists have the same length (that is, it's not a jagged array).

git diff mybranch master -- file

should also work

You can also set

-Djava.net.useSystemProxies=true

On Windows and Linux this will use the system settings so you don't need to repeat yourself (DRY)

http://docs.oracle.com/javase/7/docs/api/java/net/doc-files/net-properties.html#Proxies

Run your cmd as administrator this will solve my issues. Thanks.

An easy, loop-free alternative is to use the horizontalalignment Text property as a keyword argument to xticks[1]. In the below, at the commented line, I've forced the xticks alignment to be "right".

n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]
fig, ax = plt.subplots()
ax.plot(x,y, 'o-')

plt.xticks(
        [0,1,2,3,4],
        ["this label extends way past the figure's left boundary",
        "bad motorfinger", "green", "in the age of octopus diplomacy", "x"], 
        rotation=45,
        horizontalalignment="right")    # here
plt.show()

(yticks already aligns the right edge with the tick by default, but for xticks the default appears to be "center".)

[1] You find that described in the xticks documentation if you search for the phrase "Text properties".

The httpd dæmon on OpenBSD uses the following stylesheet for all of its error messages, which presumably covers all the Comic Sans variations on non-Windows systems:

http://openbsd.su/src/usr.sbin/httpd/server_http.c#server_abort_http

810    style = "body { background-color: white; color: black; font-family: "
811        "'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif; }\n"
812        "hr { border: 0; border-bottom: 1px dashed; }\n";

E.g., try this:

font-family: 'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif;

My suggestion would be to use a StringIO object. They emulate files, but reside in memory. So you could do something like this:

# get_zip_data() gets a zip archive containing 'foo.txt', reading 'hey, foo'

import zipfile
from StringIO import StringIO

zipdata = StringIO()
zipdata.write(get_zip_data())
myzipfile = zipfile.ZipFile(zipdata)
foofile = myzipfile.open('foo.txt')
print foofile.read()

# output: "hey, foo"

Or more simply (apologies to Vishal):

myzipfile = zipfile.ZipFile(StringIO(get_zip_data()))
for name in myzipfile.namelist():
    [ ... ]

In Python 3 use BytesIO instead of StringIO:

import zipfile
from io import BytesIO

filebytes = BytesIO(get_zip_data())
myzipfile = zipfile.ZipFile(filebytes)
for name in myzipfile.namelist():
    [ ... ]

I was facing the similar type of issue: Code Snippet :

<c:forEach items="${orderList}" var="xx"> ${xx.id} <br>
</c:forEach>

There was a space after orderlist like this : "${orderList} " because of which the xx variable was getting coverted into String and was not able to call xx.id.

So make sure about space. They play crucial role sometimes. :p

import os

dir="/path/to/dir"
[x[0]+"/"+f for x in os.walk(dir) for f in x[2] if f.endswith(".jpg")]

This will give you a list of jpg files with their full path. You can replace x[0]+"/"+f with f for just filenames. You can also replace f.endswith(".jpg") with whatever string condition you wish.

The compiler doesn't know that spe_context_ptr_t is a type. Check that the appropriate typedef is in scope when this code is compiled. You may have forgotten to include the appropriate header file.

I think what's happening, is that, since the wrapper id is relatively position, it just appears on the same position with the body tag, what you should do, is that you can add a Z-index to the wrapper id.

#wrapper {
margin: auto;
text-align: left;
width: 832px;
position: relative;
padding-top: 27px;
z-index: 99; /* added this line */
 }

This should make layers above the transparent body tag.

int cores = Runtime.getRuntime().availableProcessors();

If cores is less than one, either your processor is about to die, or your JVM has a serious bug in it, or the universe is about to blow up.

Microsoft Outlook 2002 and above removes "extra line breaks" from text messages by default (kb308319). That is, Outlook seems to simply ignore line feed and/or carriage return sequences in text messages, running all of the lines together.

This can cause problems if you're trying to write code that will automatically generate an email message to be read by someone using Outlook.

For example, suppose you want to supply separate pieces of information each on separate lines for clarity, like this:

Transaction needs attention!
PostedDate: 1/30/2009
Amount: $12,222.06
TransID: 8gk288g229g2kg89
PostalCode: 91543

Your Outlook recipient will see the information all smashed together, as follows:

Transaction needs attention! PostedDate: 1/30/2009 Amount: $12,222.06 TransID: 8gk288g229g2kg89 ZipCode: 91543

There doesn't seem to be an easy solution. Alternatives are:

1. You can supply two sets of line breaks between each line. That does stop Outlook from combining the lines onto one line, but it then displays an extra blank line between each line (creating the opposite problem). By "supply two sets of line breaks" I mean you should use "\r\n\r\n" or "\r\r" or "\n\n" but not "\r\n" or "\n\r".
2. You can supply two spaces at the beginning of every line in the body of your email message. That avoids introducing an extra blank line between each line. But this works best if each line in your message is fairly short, because the user may be previewing the text in a very narrow Outlook window that wraps the end of each line around to the first position on the next line, where it won't line up with your two-space-indented lines. This strategy has been used for some newsletters.
3. You can give up on using a plain text format, and use an html format.

You can set values from html like this. I don't think there is a direct solution from angular yet.

 <div style="visibility: hidden;">{{activeTitle='home'}}</div>

In macOS 10.10+ / iOS 8.0+ (NS)DateComponentsFormatter has been introduced to create a readable string.

It considers the user's locale und language.

let interval = 27005

let formatter = DateComponentsFormatter()
formatter.allowedUnits = [.hour, .minute, .second]
formatter.unitsStyle = .full

let formattedString = formatter.string(from: TimeInterval(interval))!
print(formattedString)

The available unit styles are positional, abbreviated, short, full, spellOut and brief.

For more information please read the documenation.

Nothing in the example says that the "classes implementing the same interface". MovieCatalog is a type and CustomerPreferenceDao is another type. Spring can easily tell them apart.

In Spring 2.x, wiring of beans mostly happened via bean IDs or names. This is still supported by Spring 3.x but often, you will have one instance of a bean with a certain type - most services are singletons. Creating names for those is tedious. So Spring started to support "autowire by type".

What the examples show is various ways that you can use to inject beans into fields, methods and constructors.

The XML already contains all the information that Spring needs since you have to specify the fully qualified class name in each bean. You need to be a bit careful with interfaces, though:

This autowiring will fail:

 @Autowired
 public void prepare( Interface1 bean1, Interface1 bean2 ) { ... }

Since Java doesn't keep the parameter names in the byte code, Spring can't distinguish between the two beans anymore. The fix is to use @Qualifier:

 @Autowired
 public void prepare( @Qualifier("bean1") Interface1 bean1,
     @Qualifier("bean2")  Interface1 bean2 ) { ... }

Example 3 in the Ruby's net/http documentation shows how to download a document over HTTP, and to output the file instead of just loading it into memory, substitute puts with a binary write to a file, e.g. as shown in Dejw's answer.

More complex cases are shown further down in the same document.

This a late answer, but I am putting it out there anyway for any new programmers to see:

If you do not want to use regular expressions, and do not wish to rely on a third party library, you can use this method instead, which takes between 89920 and 100113 nanoseconds in a 2.80 GHz CPU (less than a millisecond). It's not as pretty as Simon Nickerson's example, but it works:

   /**

     * length(s).
     * 
     * @param string
     *            the string to split.
     * @param defaultLength
     *            the default length used for any extra substrings. If set to
     *            <code>0</code>, the last substring will start at the sum of

     * @param lengths
     *            the lengths of each substring in order. If any substring is not

    public static String[] divideString(String string, int defaultLength, int... lengths) {

            parts.add(string.substring(0, defaultLength));
            string = string.substring(defaultLength);

There is a useful guide to the various methods of merging, joining and concatenating online.

For example, as you have no clashing columns you can merge and use the indices as they have the same number of rows:

In [6]:

df_a.merge(df_b, left_index=True, right_index=True)
Out[6]:
        AAseq Biorep  Techrep Treatment     mz      AAseq1 Biorep1  Techrep1  \

And for the same reasons as above a simple join works too:

If its working when you are using a browser and then passing on your username and password for the first time - then this means that once authentication is done Request header of your browser is set with required authentication values, which is then passed on each time a request is made to hosting server.

So start with inspecting Request Header (this could be done using Web Developers tools), Once you established whats required in header then you could pass this within your HttpWebRequest Header.

Example with Digest Authentication:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;
using System.Text.RegularExpressions;
using System.Net;
using System.IO;

namespace NUI
{
    public class DigestAuthFixer
    {
        private static string _host;
        private static string _user;
        private static string _password;
        private static string _realm;
        private static string _nonce;
        private static string _qop;
        private static string _cnonce;
        private static DateTime _cnonceDate;
        private static int _nc;

public DigestAuthFixer(string host, string user, string password)
{
    // TODO: Complete member initialization
    _host = host;
    _user = user;
    _password = password;
}

private string CalculateMd5Hash(
    string input)
{
    var inputBytes = Encoding.ASCII.GetBytes(input);
    var hash = MD5.Create().ComputeHash(inputBytes);
    var sb = new StringBuilder();
    foreach (var b in hash)
        sb.Append(b.ToString("x2"));
    return sb.ToString();
}

private string GrabHeaderVar(
    string varName,
    string header)
{
    var regHeader = new Regex(string.Format(@"{0}=""([^""]*)""", varName));
    var matchHeader = regHeader.Match(header);
    if (matchHeader.Success)
        return matchHeader.Groups[1].Value;
    throw new ApplicationException(string.Format("Header {0} not found", varName));
}

private string GetDigestHeader(
    string dir)
{
    _nc = _nc + 1;

    var ha1 = CalculateMd5Hash(string.Format("{0}:{1}:{2}", _user, _realm, _password));
    var ha2 = CalculateMd5Hash(string.Format("{0}:{1}", "GET", dir));
    var digestResponse =
        CalculateMd5Hash(string.Format("{0}:{1}:{2:00000000}:{3}:{4}:{5}", ha1, _nonce, _nc, _cnonce, _qop, ha2));

    return string.Format("Digest username=\"{0}\", realm=\"{1}\", nonce=\"{2}\", uri=\"{3}\", " +
        "algorithm=MD5, response=\"{4}\", qop={5}, nc={6:00000000}, cnonce=\"{7}\"",
        _user, _realm, _nonce, dir, digestResponse, _qop, _nc, _cnonce);
}

public string GrabResponse(
    string dir)
{
    var url = _host + dir;
    var uri = new Uri(url);

    var request = (HttpWebRequest)WebRequest.Create(uri);

    // If we've got a recent Auth header, re-use it!
    if (!string.IsNullOrEmpty(_cnonce) &&
        DateTime.Now.Subtract(_cnonceDate).TotalHours < 1.0)
    {
        request.Headers.Add("Authorization", GetDigestHeader(dir));
    }

    HttpWebResponse response;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
    }
    catch (WebException ex)
    {
        // Try to fix a 401 exception by adding a Authorization header
        if (ex.Response == null || ((HttpWebResponse)ex.Response).StatusCode != HttpStatusCode.Unauthorized)
            throw;

        var wwwAuthenticateHeader = ex.Response.Headers["WWW-Authenticate"];
        _realm = GrabHeaderVar("realm", wwwAuthenticateHeader);
        _nonce = GrabHeaderVar("nonce", wwwAuthenticateHeader);
        _qop = GrabHeaderVar("qop", wwwAuthenticateHeader);

        _nc = 0;
        _cnonce = new Random().Next(123400, 9999999).ToString();
        _cnonceDate = DateTime.Now;

        var request2 = (HttpWebRequest)WebRequest.Create(uri);
        request2.Headers.Add("Authorization", GetDigestHeader(dir));
        response = (HttpWebResponse)request2.GetResponse();
    }
    var reader = new StreamReader(response.GetResponseStream());
    return reader.ReadToEnd();
}

}

Then you could call it:

DigestAuthFixer digest = new DigestAuthFixer(domain, username, password);
string strReturn = digest.GrabResponse(dir);

if Url is: http://xyz.rss.com/folder/rss then domain: http://xyz.rss.com (domain part) dir: /folder/rss (rest of the url)

you could also return it as stream and use XmlDocument Load() method.

Just another variation:

    <body>
    <button name="redirect" onClick="redirect()">

    <script type="text/javascript">
    function redirect()
    {
    var url = "http://www.(url).com";
    window.location(url);
    }
    </script>

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

All three are not the conventions.

Use com.stackoverflow.mypackage.

The package names do not follow camel casing or underscores or hyphens package naming convention.

Also, Google Java Style Guide specifies exactly the same (i.e. com.stackoverflow.mypackage) convention:

5.2.1 Package names

Package names are all lowercase, with consecutive words simply concatenated together (no underscores). For example, com.example.deepspace, not com.example.deepSpace or com.example.deep_space.

I create HashMaps in bash 3 using dynamic variables. I explained how that works in my answer to: Associative arrays in Shell scripts

Also you can take a look in shell_map, which is a HashMap implementation made in bash 3.

if(!rsData.IsDBNull(rsData.GetOrdinal("usr.ursrdaystime")))
{
  strLevel = rsData.GetString("usr.ursrdaystime"); 
}

Modern string formatting:

"{} and {}".format("string", 1)

For those it might help, I use this list as a reference to define my content-type when I have to deal with images on my app.

It says that jpg extension can be declared with Content-type : image/jpeg

There isn't any image/jpg attribute for content-type.

As per limitations in Java, unsigned byte is almost impossible in the current data-type format. You can go for some other libraries of another language for what you are implementing and then you can call them using JNI.

Just do:

brew install python
brew link python

After doing that, add this to your bashrc or bash_profile:

alias python='/usr/local/bin/python2'

Enjoy!

Solutions above are good but they require ~/.bash_profile. /usr/local/bin is already in the $PATH and it can be confirmed by doing echo $PATH. Download maven and run the following commands -

$ cd ~/Downloads
$ tar xvf apache-maven-3.5.3-bin.tar.gz
$ mv apache-maven-3.5.3 /usr/local/
$ cd /usr/local/bin
$ sudo ln -s ../apache-maven-3.5.3/bin/mvn mvn
$ mvn -version
$ which mvn

Note: The version of apache maven would be the one you will download.

It's an HtmlGenericControl so not sure what the recommended way to do this is, so you could also do:

testSpace.Attributes.Add("style", "text-align: center;");

or

testSpace.Attributes.Add("class", "centerIt");

or

testSpace.Attributes["style"] = "text-align: center;";

or

testSpace.Attributes["class"] = "centerIt";

Encapsulation is to hide the variables or something inside a class, preventing unauthorized parties to use. So the public methods like getter and setter access it and the other classes call these methods for accessing

Abstraction involves the facility to define objects that represent abstract "actors" that can perform work, report on and change their state, and "communicate" with other objects in the system.

Consider the below real time example:

Encapsulation: As a driver you know how to start the car by pressing the start button and internal details of the starting operations are hidden from you. So the entire starting process is hidden from you otherwise we can tell starting operation is encapsulated from you.

OR

The driving wheel is encapsulated the process of rotating the wheel from you.

Abstraction:

Before mentioning anything about abstraction, we can take three different users here (I am calling them as entity)

1) You 2) Local Mechanic 3) Expert

You Entity: Since you know only to start the car by pressing a button and all other operations behind the scene are abstracted from you.

Local Mechanic Entity: Our local mechanic knows some of the implementation of starting the car, i.e. he can open car's bonnet and check the battery cable or chock etc. So in short Local Mechanic Entity knows some of the implementations of the car.

Expert Entity: Since our expert (Designer of the car) mechanic knows all the operations of our car, he can repair it very quickly. So in short Expert Entity knows all the implementations of the car.

The car's operation is completely abstracted from you and it is partially implemented to Local Mechanic Entity and fully implemented to Expert Entity. So you are an abstract class having only abstract methods, Local Mechanic Entity has extended You(Since he is also an ordinary user) and he implemented some of the methods and last our expert Entity extending Local Mechanic and implementing all the methods.

I think this is a good example.

Example using StringTokenizer class :

String st = "  hello all students";
String st1;
char f;
String fs="";
StringTokenizer a= new StringTokenizer(st);
while(a.hasMoreTokens()){   
        st1=a.nextToken();
        f=Character.toUpperCase(st1.charAt(0));
        fs+=f+ st1.substring(1);
        System.out.println(fs);
} 

I hacked together another way to do it without having to manipulate list view. Unfortunately, regular Android Animations seem to manipulate the contents of the row, but are ineffectual at actually shrinking the view. So, first consider this handler:

private Handler handler = new Handler() {
@Override
public void handleMessage(Message message) {
    Bundle bundle = message.getData();

    View view = listView.getChildAt(bundle.getInt("viewPosition") - 
        listView.getFirstVisiblePosition());

    int heightToSet;
    if(!bundle.containsKey("viewHeight")) {
        Rect rect = new Rect();
        view.getDrawingRect(rect);
        heightToSet = rect.height() - 1;
    } else {
        heightToSet = bundle.getInt("viewHeight");
    }

    setViewHeight(view, heightToSet);

    if(heightToSet == 1)
        return;

    Message nextMessage = obtainMessage();
    bundle.putInt("viewHeight", (heightToSet - 5 > 0) ? heightToSet - 5 : 1);
    nextMessage.setData(bundle);
    sendMessage(nextMessage);
}

Add this collection to your List adapter:

private Collection<Integer> disabledViews = new ArrayList<Integer>();

and add

public boolean isEnabled(int position) {
   return !disabledViews.contains(position);
}

Next, wherever it is that you want to hide a row, add this:

Message message = handler.obtainMessage();
Bundle bundle = new Bundle();
bundle.putInt("viewPosition", listView.getPositionForView(view));
message.setData(bundle);
handler.sendMessage(message);    
disabledViews.add(listView.getPositionForView(view));

That's it! You can change the speed of the animation by altering the number of pixels that it shrinks the height at once. Not real sophisticated, but it works!

I think Maven gets a bad rap because it imposes structure on your project, whereas other tools such as Ant allow you to completely define the structure any way you wish. Agreed also that the documentation is bad, but I think primarily the bad rap that Maven gets is because people are so used to Ant.

If you wish to have a progress bar without adding some code PACE can be an awesome tool for you.

Just include pace.js and a CSS theme of your choice, and you get a beautiful progress indicator for your page load and AJAX navigation. Best thing with PACE is the auto detection of progress.

It contains various themes and color schemes as well.

Worth a try.

As other people have answered, .cshtml (or .vbhtml if that's your flavor) provides a handler-mapping to load the MVC engine. The .aspx extension simply loads the aspnet_isapi.dll that performs the compile and serves up web forms. The difference in the handler mapping is simply a method of allowing the two to co-exist on the same server allowing both MVC applications and WebForms applications to live under a common root.

This allows http://www.mydomain.com/MyMVCApplication to be valid and served with MVC rules along with http://www.mydomain.com/MyWebFormsApplication to be valid as a standard web form.

Edit:
As for the difference in the technologies, the MVC (Razor) templating framework is intended to return .Net pages to a more RESTful "web-based" platform of templated views separating the code logic between the model (business/data objects), the view (what the user sees) and the controllers (the connection between the two). The WebForms model (aspx) was an attempt by Microsoft to use complex javascript embedding to simulate a more stateful application similar to a WinForms application complete with events and a page lifecycle that would be capable of retaining its own state from page to page.

The choice to use one or the other is always going to be a contentious one because there are arguments for and against both systems. I for one like the simplicity in the MVC architecture (though routing is anything but simple) and the ease of the Razor syntax. I feel the WebForms architecture is just too heavy to be an effective web platform. That being said, there are a lot of instances where the WebForms framework provides a very succinct and usable model with a rich event structure that is well defined. It all boils down to the needs of the application and the preferences of those building it.

You can do a precheck with regular expression wheather they are numbers as like

function myFunction() {
    var y = document.getElementById("txt1").value;
    var z = document.getElementById("txt2").value;
    if((x.search(/[^0-9]/g) != -1)&&(y.search(/[^0-9]/g) != -1))
      var x = Number(y)+ Number(z);
    else
      alert("invalid values....");
    document.getElementById("demo").innerHTML = x;
  }

for multiple classes situation, as @jbojcic mentioned above, you can use:

host: {class: 'A B C'}

Flipped structure might no longer be a map but rather a multimap, thus in the flip_map example above not all elements from B will necessarily appear in the resulting data structure.

To get a negative version of a number in JavaScript you can always use the ~ bitwise operator.

For example, if you have a = 1000 and you need to convert it to a negative, you could do the following:

a = ~a + 1;

Which would result in a being -1000.

Option 1: Hinting default image name

The name of the image generated by docker-compose depends on the folder name by default but you can override it by using --project-name argument:

$ docker-compose --project-name foo build bar
$ docker images foo_bar

Option 2: Specifying image name

Once docker-compose 1.6.0 is out, you may specify build: and image: to have an explicit image name (see arulraj.net's answer).

Option 3: Create image from container

A third is to create an image from the container:

$ docker-compose up -d bar
$ docker commit $(docker-compose ps -q bar) foo_bar
$ docker-compose rm -f bar

When I downloaded chromedriver.exe I just move it in PATH folder C:\Windows\System32\chromedriver.exe and had exact same problem.

For me solution was to just change folder in PATH, so I just moved it at Pycharm Community bin folder that was also in PATH. ex:

• C:\Windows\System32\chromedriver.exe --> Gave me exception
• C:\Program Files\JetBrains\PyCharm Community Edition 2019.1.3\bin\chromedriver.exe --> worked fine

For positive integers as arguments and where argument order doesn't matter:

1. Here's an unordered pairing function:

   <x, y> = x * y + trunc((|x - y| - 1)^2 / 4) = <y, x>
   

2. For x ? y, here's a unique unordered pairing function:

   <x, y> = if x < y:
              x * (y - 1) + trunc((y - x - 2)^2 / 4)
            if x > y:
              (x - 1) * y + trunc((x - y - 2)^2 / 4)
          = <y, x>
   

A date-time object is supposed to store the information about the date, time, timezone etc., not about the formatting. You can format a date-time object into a String with the pattern of your choice using date-time formatting API.

• The date-time formatting API for the modern date-time types is in the package, java.time.format e.g. java.time.format.DateTimeFormatter, java.time.format.DateTimeFormatterBuilder etc.
• The date-time formatting API for the legacy date-time types is in the package, java.text e.g. java.text.SimpleDateFormat, java.text.DateFormat etc.

Demo using modern API:

import java.time.LocalDate;
import java.time.Month;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Locale;

public class Main {
    public static void main(String[] args) {
        ZonedDateTime zdt = ZonedDateTime.of(LocalDate.of(2012, Month.DECEMBER, 1).atStartOfDay(),
                ZoneId.of("Europe/London"));

        // Default format returned by Date#toString
        System.out.println(zdt);

        // Custom format
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd", Locale.ENGLISH);
        String formattedDate = dtf.format(zdt);
        System.out.println(formattedDate);
    }
}

Output:

2012-12-01T00:00Z[Europe/London]
2012-12-01

Learn about the modern date-time API from Trail: Date Time.

Demo using legacy API:

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import java.util.TimeZone;

public class Main {
    public static void main(String[] args) {
        Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        calendar.setTimeInMillis(0);
        calendar.set(Calendar.YEAR, 2012);
        calendar.set(Calendar.MONTH, 11);
        calendar.set(Calendar.DAY_OF_MONTH, 1);
        Date date = calendar.getTime();

        // Default format returned by Date#toString
        System.out.println(date);

        // Custom format
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
        String formattedDate = sdf.format(date);
        System.out.println(formattedDate);
    }
}

Output:

Sat Dec 01 00:00:00 GMT 2012
2012-12-01

Some more important points:

1. The java.util.Date object is not a real date-time object like the modern date-time types; rather, it represents the milliseconds from the Epoch of January 1, 1970. When you print an object of java.util.Date, its toString method returns the date-time calculated from this milliseconds value. Since java.util.Date does not have timezone information, it applies the timezone of your JVM and displays the same. If you need to print the date-time in a different timezone, you will need to set the timezone to SimpleDateFomrat and obtain the formatted string from it.
2. The date-time API of java.util and their formatting API, SimpleDateFormat are outdated and error-prone. It is recommended to stop using them completely and switch to the modern date-time API.
   • For any reason, if you have to stick to Java 6 or Java 7, you can use ThreeTen-Backport which backports most of the java.time functionality to Java 6 & 7.
   • If you are working for an Android project and your Android API level is still not compliant with Java-8, check Java 8+ APIs available through desugaring and How to use ThreeTenABP in Android Project.

Can do in simplest way

private boolean isLocationEnabled(Context context){
int mode =Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE,
                        Settings.Secure.LOCATION_MODE_OFF);
                final boolean enabled = (mode != android.provider.Settings.Secure.LOCATION_MODE_OFF);
return enabled;
}

For Windows users, you can add a system environment variable named _JAVA_OPTIONS, and set the heap size values there. The JVM should be able to grab the virtual machine options from _JAVA_OPTIONS.

$('#pass').focus(function() { 
$('#pass').replaceWith("<input id='password' size='70' type='password' value='' name='password'>");
$('#password').focus();
});

<input id='pass' size='70' type='text' value='password' name='password'>

You forget the @ID above the userId
