No idea how you got your results, since it would not sort by string value... You should reverse a1 and a2 in your example

Best way in any case (as per Mladen) is:

metrics = {"sitea.com" => 745, "siteb.com" => 9, "sitec.com" => 10 }
metrics.sort_by {|_key, value| value}
  # ==> [["siteb.com", 9], ["sitec.com", 10], ["sitea.com", 745]]

If you need a hash as a result, you can use to_h (in Ruby 2.0+)

metrics.sort_by {|_key, value| value}.to_h
  # ==> {"siteb.com" => 9, "sitec.com" => 10, "sitea.com", 745}

like:

$('#Create .myClass, #Edit .myClass').plugin({ 
    options: here
});

You can specify any number of selectors to combine into a single result. This multiple expression combinator is an efficient way to select disparate elements. The order of the DOM elements in the returned jQuery object may not be identical, as they will be in document order. An alternative to this combinator is the .add() method.

• Multiple Selector
• Add method

I know this is quite old but if you are looking for the answer to the OP's question on how to return only specified comment, you can use the $ (query) operator like this:

db.question.update({'comments.content': 'xxx'}, {'comments.$': true})

You will get useful information from here.

SELECT ticker
INTO quotedb
FROM tickerdb;

In conf directory of apache tomcat you can find context.xml file. In that edit tag as <Context reloadable="true">. this should solve the issue and you need not restart the server

You have to consider the time difference as well. For example if you compare the dates 2015-01-01 10:00 and 2015-01-02 09:00, days between those dates will return as 0 (zero) since the difference between those dates is less than 24 hours (it's 23 hours).

If your purpose is to get the exact day number between two dates, you can work around this issue like this:

// Assuming that firstDate and secondDate are defined
// ...

let calendar = NSCalendar.currentCalendar()

// Replace the hour (time) of both dates with 00:00
let date1 = calendar.startOfDayForDate(firstDate)
let date2 = calendar.startOfDayForDate(secondDate)

let flags = NSCalendarUnit.Day
let components = calendar.components(flags, fromDate: date1, toDate: date2, options: [])

components.day  // This will return the number of day(s) between dates

Swift 3 and Swift 4 Version

let calendar = Calendar.current

// Replace the hour (time) of both dates with 00:00
let date1 = calendar.startOfDay(for: firstDate)
let date2 = calendar.startOfDay(for: secondDate)

let components = calendar.dateComponents([.day], from: date1, to: date2)

slight improvement on @LukeH, there is no need to repeat the "INSERT INTO": and @realPT's answer - no need to have the SELECT:

DECLARE @MyList TABLE (Value INT) 
INSERT INTO @MyList VALUES (1),(2),(3),(4)

SELECT * FROM MyTable
WHERE MyColumn IN (SELECT Value FROM @MyList)

I use this way (for example):

$(document).on('click', '#save', function () {
    var cont = true;
    $('.field').each(function () {
        if ($(this).val() === '') {
            alert('Please fill out all fields');
            cont = false;
            return false;
        }
    });
    if (cont === false) {
        return false;
    }
    /* commands block */
});

if cont isn't false runs commands block

_msize(array) in Windows or malloc_usable_size(array) in Linux should work for the dynamic array

They need to all have the same name.

Assume I have a variable named file that contains a file. Then I could use file.write("hello\talex").

1. file.write("hello means I'm starting to write to this file.
2. \t means a tab
3. alex") is the rest I'm writing

This will be the answer:

moment.utc(moment(localdate)).format()

localdate = '2020-01-01 12:00:00'

moment(localdate)
//Moment<2020-01-01T12:00:00+08:00>

moment.utc(moment(localdate)).format()
//2020-01-01T04:00:00Z

(9.61 + "").replace('.',':')

Or if your 9.61 is already a string:

"9.61".replace('.',':')

You're trying to insert $newdate into your db. You need to convert it to a string first. Use the DateTime::format method to convert back to a string.

^{Note: Though my original answer attracted several upvotes, I decided that I could do much better. You can find my original (simplistic and misguided) answer in the edit history.}

If Microsoft had the intent of providing a means of outputting a blank line from cmd.exe, Microsoft surely would have documented such a simple operation. It is this omission that motivated me to ask this question.

So, because a means for outputting a blank line from cmd.exe is not documented, arguably one should consider any suggestion for how to accomplish this to be a hack. That means that there is no known method for outputting a blank line from cmd.exe that is guaranteed to work (or work efficiently) in all situations.

With that in mind, here is a discussion of methods that have been recommended for outputting a blank line from cmd.exe. All recommendations are based on variations of the echo command.

echo.

While this will work in many if not most situations, it should be avoided because it is slower than its alternatives and actually can fail (see here, here, and here). Specifically, cmd.exe first searches for a file named echo and tries to start it. If a file named echo happens to exist in the current working directory, echo. will fail with:

'echo.' is not recognized as an internal or external command,
operable program or batch file.

echo:
echo\

At the end of this answer, the author argues that these commands can be slow, for instance if they are executed from a network drive location. A specific reason for the potential slowness is not given. But one can infer that it may have something to do with accessing the file system. (Perhaps because : and \ have special meaning in a Windows file system path?)

However, some may consider these to be safe options since : and \ cannot appear in a file name. For that or another reason, echo: is recommended by SS64.com here.

echo(
echo+
echo,
echo/
echo;
echo=
echo[
echo]

This lengthy discussion includes what I believe to be all of these. Several of these options are recommended in this SO answer as well. Within the cited discussion, this post ends with what appears to be a recommendation for echo( and echo:.

My question at the top of this page does not specify a version of Windows. My experimentation on Windows 10 indicates that all of these produce a blank line, regardless of whether files named echo, echo+, echo,, ..., echo] exist in the current working directory. (Note that my question predates the release of Windows 10. So I concede the possibility that older versions of Windows may behave differently.)

In this answer, @jeb asserts that echo( always works. To me, @jeb's answer implies that other options are less reliable but does not provide any detail as to why that might be. Note that @jeb contributed much valuable content to other references I have cited in this answer.

Conclusion: Do not use echo.. Of the many other options I encountered in the sources I have cited, the support for these two appears most authoritative:

echo(
echo:

But I have not found any strong evidence that the use of either of these will always be trouble-free.

Example Usage:

@echo off
echo Here is the first line.
echo(
echo There is a blank line above this line.

Expected output:

Here is the first line.

There is a blank line above this line.

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

this might be repetitive. I was trying to use pycharm to run flask - had anaconda 3, pycharm 2019.1.1 and windows 10. Created a new conda environment - it threw errors. Followed these steps -

1. Used the cmd to install python and flask after creating environment as suggested above.

2. Followed this answer.

3. As suggested above, went to Run -> Edit Configurations and changed the environment there as well as in (2).

Obviously kept the correct python interpreter (the one in the environment) everywhere.

TLS 1.2 is only supported since OpenSSL 1.0.1 (see the Major version releases section), you have to update your OpenSSL.

It is not necessary to set the CURLOPT_SSLVERSION option. The request involves a handshake which will apply the newest TLS version both server and client support. The server you request is using TLS 1.2, so your php_curl will use TLS 1.2 (by default) as well if your OpenSSL version is (or newer than) 1.0.1.

In Java there is no direct way to get browser and OS related information.

But to get this few third-party tools are available.

Instead of trusting third-party tools, I suggest you to parse the user agent.

String  browserDetails  =   request.getHeader("User-Agent");

By doing this you can separate the browser details and OS related information easily according to your requirement. PFB the snippet for reference.

        String  browserDetails  =   request.getHeader("User-Agent");
        String  userAgent       =   browserDetails;
        String  user            =   userAgent.toLowerCase();

        String os = "";
        String browser = "";

A colleague told me to use scm.branches[0].name and it worked. I wrapped it to a function in my Jenkinsfile:

You have an invalid character on that line. This is what I saw:

There is another simple sql like option. With Spark 1.6 below also should work.

df.filter("state = 'TX'")

This is a new way of specifying sql like filters. For a full list of supported operators, check out this class.

I found a good way to do this with using a function and basic code. This is a code that accepts a string and counts the number of capital letters, lowercase letters and also 'other'. Other is classed as a space, punctuation mark or even Japanese and Chinese characters.

def check(count):

    lowercase = 0
    uppercase = 0
    other = 0

    low = 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'
    upper = 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'



    for n in count:
        if n in low:
            lowercase += 1
        elif n in upper:
            uppercase += 1
        else:
            other += 1

    print("There are " + str(lowercase) + " lowercase letters.")
    print("There are " + str(uppercase) + " uppercase letters.")
    print("There are " + str(other) + " other elements to this sentence.")

Set all the column's (which can be sortable by users) SortMode property to Automatic

dataGridView1.DataSource = students.Select(s => new { ID = s.StudentId, RUDE = s.RUDE, Nombre = s.Name, Apellidos = s.LastNameFather + " " + s.LastNameMother, Nacido = s.DateOfBirth })
                                   .OrderBy(s => s.Apellidos)
                                   .ToList();

    foreach(DataGridViewColumn column in dataGridView1.Columns)
    {
    
        column.SortMode = DataGridViewColumnSortMode.Automatic;
    }

Edit: As your datagridview is bound with a linq query, it will not be sorted. So please go through this [404 dead link, see next section] which explains how to create a sortable binding list and to then feed it as datasource to datagridview.

Code as recovered from dead link

Link from above is 404-dead. I recovered the code from the Internet Wayback Machine archive of the page.

    persons.Add(new Person(2, "John Doe", DateTime.Now));

    this.dataGridView1.AutoGenerateColumns = false;
    this.ColumnId.DataPropertyName = "Id";

Just wanted to let you know that up until today I was first obtaining an app access token (via GET request to Facebook), and then using the received token as the app-token-or-admin-token in:

GET graph.facebook.com/debug_token?
    input_token={token-to-inspect}
    &access_token={app-token-or-admin-token}

However, I just realized a better way of doing this (with the added benefit of requiring one less GET request):

GET graph.facebook.com/debug_token?
    input_token={token-to-inspect}
    &access_token={app_id}|{app_secret}

As described in Facebook's documentation for Access Tokens here.

Getting into the gray area of "on/off topic", but necessary to eliminate confusion regarding Oscar Reyes suggestion that more hash collisions is a good thing because it reduces the number of elements in the HashMap. I may misunderstand what Oscar is saying, but I don't seem to be the only one: kdgregory, delfuego, Nash0, and I all seem to share the same (mis)understanding.

If I understand what Oscar is saying about the same class with the same hashcode, he's proposing that only one instance of a class with a given hashcode will be inserted into the HashMap. Eg, if I have an instance of SomeClass with a hashcode of 1 and a second instance of SomeClass with a hashcode of 1, only one instance of SomeClass is inserted.

The Java pastebin example at http://pastebin.com/f20af40b9 seems to indicate the above correctly summarizes what Oscar is proposing.

Regardless of any understanding or misunderstanding, what happens is different instances of the same class do not get inserted only once into the HashMap if they have the same hashcode - not until it's determined whether the keys are equal or not. The hashcode contract requires that equal objects have the same hashcode; however, it doesn't require that unequal objects have different hashcodes (although this may be desirable for other reasons)[1].

The pastebin.com/f20af40b9 example (which Oscar refers to at least twice) follows, but modified slightly to use JUnit assertions rather than printlines. This example is used to support the proposal that the same hashcodes cause collisions and when the classes are the same only one entry is created (eg, only one String in this specific case):

@Test
public void shouldOverwriteWhenEqualAndHashcodeSame() {
    String s = new String("ese");
    String ese = new String("ese");
    // same hash right?
    assertEquals(s.hashCode(), ese.hashCode());
    // same class
    assertEquals(s.getClass(), ese.getClass());
    // AND equal
    assertTrue(s.equals(ese));

    Map map = new HashMap();
    map.put(s, 1);
    map.put(ese, 2);
    SomeClass some = new SomeClass();
    // still  same hash right?
    assertEquals(s.hashCode(), ese.hashCode());
    assertEquals(s.hashCode(), some.hashCode());

    map.put(some, 3);
    // what would we get?
    assertEquals(2, map.size());

    assertEquals(2, map.get("ese"));
    assertEquals(3, map.get(some));

    assertTrue(s.equals(ese) && s.equals("ese"));
}

class SomeClass {
    public int hashCode() {
        return 100727;
    }
}

However, the hashcode isn't the complete story. What the pastebin example neglects is the fact that both s and ese are equal: they are both the string "ese". Thus, inserting or getting the contents of the map using s or ese or "ese" as the key are all equivalent because s.equals(ese) && s.equals("ese").

A second test demonstrates it is erroneous to conclude that identical hashcodes on the same class is the reason the key -> value s -> 1 is overwritten by ese -> 2 when map.put(ese, 2) is called in test one. In test two, s and ese still have the same hashcode (as verified by assertEquals(s.hashCode(), ese.hashCode());) AND they are the same class. However, s and ese are MyString instances in this test, not Java String instances - with the only difference relevant for this test being the equals: String s equals String ese in test one above, whereas MyStrings s does not equal MyString ese in test two:

@Test
public void shouldInsertWhenNotEqualAndHashcodeSame() {
    MyString s = new MyString("ese");
    MyString ese = new MyString("ese");
    // same hash right?
    assertEquals(s.hashCode(), ese.hashCode());
    // same class
    assertEquals(s.getClass(), ese.getClass());
    // BUT not equal
    assertFalse(s.equals(ese));

    Map map = new HashMap();
    map.put(s, 1);
    map.put(ese, 2);
    SomeClass some = new SomeClass();
    // still  same hash right?
    assertEquals(s.hashCode(), ese.hashCode());
    assertEquals(s.hashCode(), some.hashCode());

    map.put(some, 3);
    // what would we get?
    assertEquals(3, map.size());

    assertEquals(1, map.get(s));
    assertEquals(2, map.get(ese));
    assertEquals(3, map.get(some));
}

/**
 * NOTE: equals is not overridden so the default implementation is used
 * which means objects are only equal if they're the same instance, whereas
 * the actual Java String class compares the value of its contents.
 */
class MyString {
    String i;

    MyString(String i) {
        this.i = i;
    }

    @Override
    public int hashCode() {
        return 100727;
    }
}

Based on a later comment, Oscar seems to reverse what he's said earlier and acknowledges the importance of equals. However, it still seems the notion that equals is what matters, not the "same class", is unclear (emphasis mine):

"Not really. The list is created only if the hash is the same, but the key is different. For instance if a String give hashcode 2345 and and Integer gives the same hashcode 2345, then the integer is inserted into the list because String.equals( Integer ) is false. But if you have the same class ( or at least .equals returns true ) then the same entry is used. For instance new String("one") and `new String("one") used as keys, will use the same entry. Actually this is the WHOLE point of HashMap in first place! See for yourself: pastebin.com/f20af40b9 – Oscar Reyes"

versus earlier comments that explicitly address the importance of identical class and same hashcode, with no mention of equals:

"@delfuego: See for yourself: pastebin.com/f20af40b9 So, in this question the same class is being used ( wait a minute, the same class is being used right? ) Which implies that when the same hash is used the same entry is used and there is not "list" of entries. – Oscar Reyes"

or

"Actually this would increase the performance. The more collisions eq less entries in the hashtable eq. less work to do. Is not the hash ( which looks fine ) nor the hashtable ( which works great ) I'd bet it is on the object creation where the performance is degrading. – Oscar Reyes"

or

"@kdgregory: Yes, but only if the collision happens with different classes, for the same class ( which is the case ) the same entry is used. – Oscar Reyes"

Again, I may misunderstand what Oscar was actually trying to say. However, his original comments have caused enough confusion that it seems prudent to clear everything up with some explicit tests so there are no lingering doubts.

[1] - From Effective Java, Second Edition by Joshua Bloch:

• Whenever it is invoked on the same object more than once during an execution of an application, the hashCode method must consistently return the same integer, provided no information used in equal s comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.

• If two objects are equal according to the equal s(Obj ect) method, then calling the hashCode method on each of the two objects must produce the same integer result.

• It is not required that if two objects are unequal according to the equal s(Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

For efficiency's sake you want to only hit the data once, as Harper does. However you don't want to use rank() because it will give you ties and further you want to group by language rather than order by language. From there you want add an order by clause to distinguish between rows, but you don't want to actually sort the data. To achieve this I would use "order by null" E.g.

count(*) over (group by language order by null)

Have read alot about this and the only solution that worked for me was to create a new project and then copy old project back into it.

Use the command svn status on your working copy to show the status of files, files that are not yet under version control (and not ignored) will have a question mark next to them.

As for ignoring files you need to edit the svn:ignore property, read the chapter Ignoring Unversioned Items in the svnbook at http://svnbook.red-bean.com/en/1.5/svn.advanced.props.special.ignore.html. The book also describes more about using svn status.

If you just want to make sure a certain file exists (f.ex. because it shoud be created in a different way than via ansible) and fail if it doesn't, then you can do this:

- name: sanity check that /some/path/file exists
  command: stat /some/path/file
  check_mode: no # always run
  changed_when: false # doesn't change anything

To fix the indentation and formatting in all files of your solution:

1. Install the Format All Files extension => close VS, execute the .vsix file and reopen VS;
2. Menu Tools > Options... > Text Editor > All Languages > Tabs:
   1. Click on Smart (for resolving conflicts);
   2. Type the Tab Size and Indent Size you want (e.g. 2);
   3. Click on Insert Spaces if you want to replace tabs by spaces;
3. In the Solution Explorer (Ctrl+Alt+L) right click in any file and choose from the menu Format All Files (near the bottom).

This will recursively open and save all files in your solution, setting the indentation you defined above.

You might want to check other programming languages tabs (Options...) for Code Style > Formatting as well.

I have a simple solution for this problem. You can first type ":retab" and then ":retab!", then everything would be fine

You can use Java 7's Key and Certificate Management Tool keytool to check the signature of a keystore or an APK without extracting any files.

Signature of an APK or AAB

# APK file
keytool -printcert -jarfile app.apk

# AAB file
keytool -printcert -jarfile app.aab

The output will reveal the signature owner/issuer and MD5, SHA1 and SHA256 fingerprints of the APK file app.apk or AAB file app.aab.

(Note that the -jarfile argument was introduced in Java 7; see the documentation for more details.)

Signature of a keystore

keytool -list -v -keystore release.jks

The output will reveal the aliases (entries) in the keystore file release.jks, with the certificate fingerprints (MD5, SHA1 and SHA256).

If the SHA1 fingerprints between the APK and the keystore match, then you can rest assured that that app is signed with the key.

This is a bit old but I found a better solution for this. I was trying the chosen answer here but looks like .testrunconfig is already obsolete.

1. For Unit Tests, Wrap the config is an Interface (IConfig)

for Unit tests, config really shouldn't be part of what your testing so create a mock which you can inject. In this example I was using Moq.

Mock<IConfig> _configMock;
_configMock.Setup(config => config.ConfigKey).Returns("ConfigValue");
var SUT = new SUT(_configMock.Object);

2. For Integration test, dynamically add the config you need

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
if(config.AppSettings.Settings[configName] != null)
{
    config.AppSettings.Settings.Remove(configName);
}
config.AppSettings.Settings.Add(configName, configValue);
config.Save(ConfigurationSaveMode.Modified, true);
ConfigurationManager.RefreshSection("appSettings");

Version 51 is Java 7, you probably use the wrong JDK. Check JAVA_HOME.

As mentioned here, under Binary Compatibility

i could have been only one who made this mistake but maybe not so i'll post.

the format for annotations in the comments before a route has to start with a slash and two asterisks. i was making the mistake of a slash and only one asterisk, which PHPStorm autocompleted.

my route looked like this:

/*
 * @Route("/",name="homepage")
 */
public function indexAction(Request $request) {
    return $this->render('default/index.html.twig');
}

when it should have been this

/**
 * @Route("/",name="homepage")
 */
public function indexAction(Request $request) {
    return $this->render('default/base.html.twig');
}

You can also reset page number counter:

\setcounter{page}{1}

However, with this technique you get wrong page numbers in Acrobat in the top left page numbers field:

\maketitle: 1
\tableofcontents: 2
\setcounter{page}{1}
\section{Introduction}: 1
...

I would use the property display: table-cell

Not really, no.

You may be able to achieve the same effect by using reflection to get Method objects you can then invoke, and the other way is to create an interface with a single 'invoke' or 'execute' method, and then instantiate them to call the method your interested in (i.e. using an anonymous inner class).

My answer is based on Triptych's, but improves a lot on it. It is based on the fact that beyond 2 and 3, all the prime numbers are of the form 6n-1 or 6n+1.

var largestPrimeFactor;
if(n mod 2 == 0)
{
    largestPrimeFactor = 2;
    n = n / 2 while(n mod 2 == 0);
}
if(n mod 3 == 0)
{
    largestPrimeFactor = 3;
    n = n / 3 while(n mod 3 == 0);
}

multOfSix = 6;
while(multOfSix - 1 <= n)
{
    if(n mod (multOfSix - 1) == 0)
    {
        largestPrimeFactor = multOfSix - 1;
        n = n / largestPrimeFactor while(n mod largestPrimeFactor == 0);
    }

    if(n mod (multOfSix + 1) == 0)
    {
        largestPrimeFactor = multOfSix + 1;
        n = n / largestPrimeFactor while(n mod largestPrimeFactor == 0);
    }
    multOfSix += 6;
}

I recently wrote a blog article explaining how this algorithm works.

I would venture that a method in which there is no need for a test for primality (and no sieve construction) would run faster than one which does use those. If that is the case, this is probably the fastest algorithm here.

If the numbers you want to choose from are not consecutive, you can use random().

Usage:

val list = listOf(3, 1, 4, 5)
val number = list.random()

Returns one of the numbers which are in the list.

$ git rebase --abort

Run this code at any time if you want to undo the git rebase

$ git rebase -i HEAD~2

To reapply last two commits. The above command will open a code editor

• [ The latest commit will be at the bottom ]. Change the last commit to squash(s). Since squash will meld with previous commit.
• Then press esc key and type :wq to save and close

After :wq you will be in active rebase mode

Note: You'll get another editor if no warning/error messages, If there is an error or warning another editor will not show, you may abort by runnning $ git rebase --abort if you see an error or warning else just continue by running $ git rebase --continue

You will see your 2 commit message. Choose one or write your own commit message, save and quit [:wq]

Note 2: You may need to force push your changes to the remote repo if you run rebase command

$ git push -f

$ git push -f origin master

I just make with JQuery.

I tested in Firefox and IE10.

RegexBuddy is telling me if you want to include it at the beginning, this is the correct syntax:

"(?i)\\b(\\w+)\\b(\\s+\\1)+\\b"

Try this:

$time = "21:30:10";
$timeArr = array_reverse(explode(":", $time));
$seconds = 0;
foreach ($timeArr as $key => $value)
{
    if ($key > 2) break;
    $seconds += pow(60, $key) * $value;
}
echo $seconds;

A simpler option: just uncomment the following part of the configuration (which is originally commented out) in the /etc/vim/vimrc file:

    if has("autocmd")
      filetype plugin indent on
    endif

A variable cannot be both null and undefined at the same time. However, the direct answer to your question is:

if (variable != null)

One =, not two.

There are two special clauses in the "abstract equality comparison algorithm" in the JavaScript spec devoted to the case of one operand being null and the other being undefined, and the result is true for == and false for !=. Thus if the value of the variable is undefined, it's not != null, and if it's not null, it's obviously not != null.

Now, the case of an identifier not being defined at all, either as a var or let, as a function parameter, or as a property of the global context is different. A reference to such an identifier is treated as an error at runtime. You could attempt a reference and catch the error:

var isDefined = false;
try {
  (variable);
  isDefined = true;
}
catch (x) {}

I would personally consider that a questionable practice however. For global symbols that may or may be there based on the presence or absence of some other library, or some similar situation, you can test for a window property (in browser JavaScript):

var isJqueryAvailable = window.jQuery != null;

or

var isJqueryAvailable = "jQuery" in window;

converting @Anthony's answer to Swift 3.0 worked perfectly for me:

func scrollViewDidScroll(_ scrollView: UIScrollView) {

    var visibleRect = CGRect()
    visibleRect.origin = yourCollectionView.contentOffset
    visibleRect.size = yourCollectionView.bounds.size
    let visiblePoint = CGPoint(x: CGFloat(visibleRect.midX), y: CGFloat(visibleRect.midY))
    let visibleIndexPath: IndexPath? = yourCollectionView.indexPathForItem(at: visiblePoint)
    print("Visible cell's index is : \(visibleIndexPath?.row)!")
}

What your trying to do is send a whole file.

This worked for me.

You can disable it with -Wno-reorder.

All the answers provide sufficient details to the question. However, let me add something more.

Why are we using these Interfaces:

• They allow Spring to find your repository interfaces and create proxy objects for them.
• It provides you with methods that allow you to perform some common operations (you can also define your custom method as well). I love this feature because creating a method (and defining query and prepared statements and then execute the query with connection object) to do a simple operation really sucks !

Which interface does what:

• CrudRepository: provides CRUD functions
• PagingAndSortingRepository: provides methods to do pagination and sort records
• JpaRepository: provides JPA related methods such as flushing the persistence context and delete records in a batch

When to use which interface:

According to http://jtuts.com/2014/08/26/difference-between-crudrepository-and-jparepository-in-spring-data-jpa/

Generally the best idea is to use CrudRepository or PagingAndSortingRepository depending on whether you need sorting and paging or not.

The JpaRepository should be avoided if possible, because it ties you repositories to the JPA persistence technology, and in most cases you probably wouldn’t even use the extra methods provided by it.

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

I use numbers tables for primarily dummying up reports in BIRT without having to fiddle around with dynamic creation of recordsets.

I do the same with dates, having a table spanning from 10 years in the past to 10 years in the future (and hours of the day for more detailed reporting). It's a neat trick to be able to get values for all dates even if your 'real' data tables don't have data for them.

I have a script which I use to create these, something like (this is from memory):

drop table numbers; commit;
create table numbers (n integer primary key); commit;
insert into numbers values (0); commit;
insert into numbers select n+1 from numbers; commit;
insert into numbers select n+2 from numbers; commit;
insert into numbers select n+4 from numbers; commit;
insert into numbers select n+8 from numbers; commit;
insert into numbers select n+16 from numbers; commit;
insert into numbers select n+32 from numbers; commit;
insert into numbers select n+64 from numbers; commit;

The number of rows doubles with each line so it doesn't take a lot to produce truly huge tables.

I'm not sure I agree with you that it's important to be created fast since you only create it once. The cost of that is amortized over all the accesses to it, rendering that time fairly insignificant.

Thanks, but that was not the solution. I found it out why it wasn't working for me.

Since I'd done a declaration:

ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");

I thought I would refer to root directory of the project when beans.xml file was there. Then I put the configuration file to src/main/resources and changed initialization to:

ApplicationContext context = new ClassPathXmlApplicationContext("src/main/resources/beans.xml");

it still was an IO Exception.

Then the file was left in src/main/resources/ but I changed declaration to:

ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");

and it solved the problem - maybe it will be helpful for someone.

thanks and cheers!

Edit:

Since I get many people thumbs up for the solution and had had first experience with Spring as student few years ago, I feel desire to explain shortly why it works.

When the project is being compiled and packaged, all the files and subdirs from 'src/main/java' in the project goes to the root directory of the packaged jar (the artifact we want to create). The same rule applies to 'src/main/resources'.

This is a convention respected by many tools like maven or sbt in process of building project (note: as a default configuration!). When code (from the post) was in running mode, it couldn't find nothing like "src/main/resources/beans.xml" due to the fact, that beans.xml was in the root of jar (copied to /beans.xml in created jar/ear/war).

When using ClassPathXmlApplicationContext, the proper location declaration for beans xml definitions, in this case, was "/beans.xml", since this is path where it belongs in jar and later on in classpath.

It can be verified by unpacking a jar with an archiver (i.e. rar) and see its content with the directories structure.

I would recommend reading articles about classpath as supplementary.

The onclick attribute in HTML calls JavaScript functions, not PHP functions.

For parsing command line arguments on posix systems, the standard is to use the getopt() family of library routines to handle command line arguments.

I converted the VB code in the blog post linked by xsl to C# and modified it a bit:

public static bool TryGetRegisteredApplication(
                     string extension, out string registeredApp)
{
    string extensionId = GetClassesRootKeyDefaultValue(extension);
    if (extensionId == null)
    {
        registeredApp = null;
        return false;
    }

    string openCommand = GetClassesRootKeyDefaultValue(
            Path.Combine(new[] {extensionId, "shell", "open", "command"}));

    if (openCommand == null)
    {
        registeredApp = null;
        return false;
    }

    registeredApp = openCommand
                     .Replace("%1", string.Empty)
                     .Replace("\"", string.Empty)
                     .Trim();
    return true;
}

private static string GetClassesRootKeyDefaultValue(string keyPath)
{
    using (var key = Registry.ClassesRoot.OpenSubKey(keyPath))
    {
        if (key == null)
        {
            return null;
        }

        var defaultValue = key.GetValue(null);
        if (defaultValue == null)
        {
            return null;
        }

        return defaultValue.ToString();
    }
}

EDIT - this is unreliable. See Finding the default application for opening a particular file type on Windows.

if you want to do it only with the LocalDate-class:

LocalDate initial = LocalDate.of(2014, 2, 13);

LocalDate start = LocalDate.of(initial.getYear(), initial.getMonthValue(),1);

// Idea: the last day is the same as the first day of next month minus one day.
LocalDate end = LocalDate.of(initial.getYear(), initial.getMonthValue(), 1).plusMonths(1).minusDays(1);

There are two ways, one httpCookies element in web.config allows you to turn on requireSSL which only transmit all cookies including session in SSL only and also inside forms authentication, but if you turn on SSL on httpcookies you must also turn it on inside forms configuration too.

<httpCookies requireSSL="true" />

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

It provides nothing else but a standardization of the data. The values it creates are known under several different names, one of them being z-scores ("Z" because the normal distribution is also known as the "Z distribution").

If you really want your includes method on an ArrayList, just add it:

ArrayList.metaClass.includes = { i -> i in delegate }

public static string intToBinary(int n)
{
    String s = "";
    while (n > 0)
    {
        s =  ( (n % 2 ) == 0 ? "0" : "1") +s;
        n = n / 2;
    }
    return s;
}

Change the axis_colour to match the background and if you are modifying the background dynamically you will need to update the axis_colour simultaneously. * The shared picture shows the graph/plot example using mock data ()

### Main Plotting Function ###
plotXY <- function(time, value){

    ### Plot Style Settings ###

    ### default bg is white, set it the same as the axis-colour 
    background <- "white"

    ### default col.axis is black, set it the same as the background to match
    axis_colour <- "white"

    plot_title <- "Graph it!"
    xlabel <- "Time"
    ylabel <- "Value"
    label_colour <- "black"
    label_scale <- 2
    axis_scale <- 2
    symbol_scale <- 2
    title_scale <- 2
    subtitle_scale <- 2
    # point style 16 is a black dot
    point <- 16 
    # p - points, l - line, b - both
    plot_type <- "b"

    plot(time, value, main=plot_title, cex=symbol_scale, cex.lab=label_scale, cex.axis=axis_scale, cex.main=title_scale, cex.sub=subtitle_scale, xlab=xlabel, ylab=ylabel, col.lab=label_colour, col.axis=axis_colour, bg=background, pch=point, type=plot_type)
}

plotXY(time, value)

Most modern RDBMSs support the INFORMATION_SCHEMA schema. If yours supports that, then you want either INFORMATION_SCHEMA.TABLE_CONSTRAINTS or INFORMATION_SCHEMA.KEY_COLUMN_USAGE, or maybe both.

To see if yours supports it is as simple as running

select count(*) from INFORMATION_SCHEMA.TABLE_CONSTRAINTS

EDIT: SQL Server does have INFORMATION_SCHEMA, and it's easier to use than their vendor-specific tables, so just go with it.

If you are using a declarative syntax of Jenkinsfile to describe your building pipeline, you can use changeset condition to limit stage execution only to the case when specific files are changed. This is now a standard feature of Jenkins and does not require any additional configruation/software.

stages {
    stage('Nginx') {
        when { changeset "nginx/*"}
        steps {
            sh "make build-nginx"
            sh "make start-nginx"
        }
    }
}

You can combine multiple conditions using anyOf or allOf keywords for OR or AND behaviour accordingly:

when {
    anyOf {
        changeset "nginx/**"
        changeset "fluent-bit/**"
    }
}
steps {
    sh "make build-nginx"
    sh "make start-nginx"
}

This worked for me:

$(window).scroll(function() {
  buffer = 40 // # of pixels from bottom of scroll to fire your function. Can be 0
  if ($(".myDiv").prop('scrollHeight') - $(".myDiv").scrollTop() <= $(".myDiv").height() + buffer )   {
    doThing();
  }
});

Since 12,200 people have looked at this question and not got an answer:

DFSORT and SyncSort are the predominant Mainframe sorting products. Their control cards have many similarities, and some differences.

JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A)              
JOINKEYS FILE=F2,FIELDS=(key2startpos,7,A)              
JOIN UNPAIRED,F1,F2
REFORMAT FIELDS=(F1:1,5200,F2:1,5200)                         
SORT FIELDS=COPY    

A "JOINKEYS" is made of three Tasks. Sub-Task 1 is the first JOINKEYS. Sub-Task 2 is the second JOINKEYS. The Main Task follows and is where the joined data is processed. In the example above it is a simple COPY operation. The joined data will simply be written to SORTOUT.

The JOIN statement defines that as well as matched records, UNPAIRED F1 and F2 records are to be presented to the Main Task.

The REFORMAT statement defines the record which will be presented to the Main Task. A more efficient example, imagining that three fields are required from F2, is:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100)

Each of the fields on F2 is defined with a start position and a length.

The record which is then processed by the Main task is 5311 bytes long, and the fields from F2 can be referenced by 5201,10,5211,1,5212,100 with the F1 record being 1,5200.

A better way achieve the same thing is to reduce the size of F2 with JNF2CNTL.

//JNF2CNTL DD *
  INREC BUILD=(207,1,10,30,1,5100,100)

Some installations of SyncSort do not support JNF2CNTL, and even where supported (from Syncsort MFX for z/OS release 1.4.1.0 onwards), it is not documented by SyncSort. For users of 1.3.2 or 1.4.0 an update is available from SyncSort to provide JNFnCNTL support.

It should be noted that JOINKEYS by default SORTs the data, with option EQUALS. If the data for a JOINKEYS file is already in sequence, SORTED should be specified. For DFSORT NOSEQCHK can also be specified if sequence-checking is not required.

 JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A),SORTED,NOSEQCHK

Although the request is strange, as the source file won't be able to be determined, all unmatched records are to go to a separate output file.

With DFSORT, there is a matching-marker, specified with ? in the REFORMAT:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100,?)

This increases the length of the REFORMAT record by one byte. The ? can be specified anywhere on the REFORMAT record, and need not be specified. The ? is resolved by DFSORT to: B, data sourced from Both files; 1, unmatched record from F1; 2, unmatched record from F2.

SyncSort does not have the match marker. The absence or presence of data on the REFORMAT record has to be determined by values. Pick a byte on both input records which cannot contain a particular value (for instance, within a number, decide on a non-numeric value). Then specify that value as the FILL character on the REFORMAT.

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100),FILL=C'$'

If position 1 on F1 cannot naturally have "$" and position 20 on F2 cannot either, then those two positions can be used to establish the result of the match. The entire record can be tested if necessary, but sucks up more CPU time.

The apparent requirement is for all unmatched records, from either F1 or F2, to be written to one file. This will require a REFORMAT statement which includes both records in their entirety:

DFSORT, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

SyncSort, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

The coding for SyncSort will also work with DFSORT.

To get the matched records written is easy.

  OUTFIL FNAMES=MATCH,SAVE

SAVE ensures that all records not written by another OUTFIL will be written here.

There is some reformatting required, to mainly output data from F1, but to select some fields from F2. This will work for either DFSORT or SyncSort:

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

The whole thing, with arbitrary starts and lengths is:

DFSORT

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)    

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

SyncSort

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)              

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

Another option (depending on the use case) would be to use DataMystic's TextPipe and DataPipe products. I've used them in the past, and they've worked great in the complex replacement scenarios, and without having to export data out of the database for find-and-replace.

What is this for and why would I use @":\" instead of ":\"?

Because when you have a long string with many \ you don't need to escape them all and the \n, \r and \f won't work too.

If possible you can change the div to an textarea and use .change().

Another solution could be use a hidden textarea and update the textarea same time as you update the div. Then use .change() on the hidden textarea.

You can also use http://www.jacklmoore.com/autosize/ to make the text area act more like a div.

<style>
.hidden{
display:none
}
</style>

<textarea class="hidden" rows="4" cols="50">

</textarea>


$("#hiddentextarea").change(function() {

alert('Textarea changed');

})

Update: It seems like textarea has to be defocused after updated, for more info: How do I set up a listener in jQuery/javascript to monitor a if a value in the textbox has changed?

what's wrong with:

int myInt = myFloat;

bear in mind this'll use the default rounding rule, which is towards zero (i.e. -3.9f becomes -3)

If you have a working copy then svn status will help.

svn status -u -v

The --show-updates (-u) option contacts the repository and adds information about things that are out of date.

In my case i found better to use "string.search".

var str = "Some very very very long string";
var n = str.search("very");

In case it would be helpful for someone.

Answering old thread here (and a bit off-topic) because it's what I found when I was searching how to install Image Magick on Mac OS to run on the local webserver. It's not enough to brew install Imagemagick. You have to also PECL install it so the PHP module is loaded.

From this SO answer:

brew install php
brew install imagemagick
brew install pkg-config
pecl install imagick

And you may need to sudo apachectl restart. Then check your phpinfo() within a simple php script running on your web server.

If it's still not there, you probably have an issue with running multiple versions of PHP on the same Mac (one through the command line, one through your web server). It's beyond the scope of this answer to resolve that issue, but there are some good options out there.

IntelliJ IDEA Plugins / GenerateSerialVersionUID https://plugins.jetbrains.com/plugin/?idea&id=185

very nice, very easy to install. you can install that from plugins menu, select install from disk, select the jar file you unpacked in the lib folder. restart, control + ins, and it pops up to generate serial UID from menu. love it. :-)

There is more than one way to do it:

1- Add your UIView on UIWindow instead of adding it on UIViewController. This way it will be on top of everything.

   [[(AppDelegate *)[UIApplication sharedApplication].delegate window] addSubview:view];

2- Use custom transition that will keep your UIViewController showing in the back with a 0.5 alpha

For that I recommend you look at this: https://github.com/Citrrus/BlurryModalSegue

Java usually doesn't like accessing hardware, so you will need a driver program of some sort, as goldenmean said. I've done this on my laptop by finding a command line program that snaps a picture. Then it's the same as goldenmean explained; you run the command line program from your java program in the takepicture() routine, and the rest of your code runs the same.

Except for the part about reading pixel values into an array, you might be better served by saving the file to BMP, which is nearly that format already, then using the standard java image libraries on it.

Using a command line program adds a dependency to your program and makes it less portable, but so was the webcam, right?

I found the above answers quite useful but not really general purpose, they all need some other major build system like Ant or Maven.

I wanted to generate a report in a simple one-shot command that I could call from anything (from a build, test or just myself) so I have created junit2html which can be found here: https://github.com/inorton/junit2html

You can install it by doing:

pip install junit2html

I would check the "End of File" flag:

If temp_rst1.EOF Or temp_rst2.EOF Then MsgBox "null"

Here's what I did. I wanted a HTML page setup on our network so I wouldn't have to navigate to various folders to install or upgrade our apps. So what I did was setup a .bat file on our "shared" drive that everyone has access to, in that .bat file I had this code:

start /d "\\server\Software\" setup.exe

The HTML code was:

<input type="button" value="Launch Installer" onclick="window.open('file:///S:Test/Test.bat')" />

(make sure your slashes are correct, I had them the other way and it didn't work)

I preferred to launch the EXE directly but that wasn't possible, but the .bat file allowed me around that. Wish it worked in FF or Chrome, but only IE.

Just add the display:block to the thead > tr and tbody. check the below example

http://www.imaputz.com/cssStuff/bigFourVersion.html

you can define a custom ScrollView class, & add an interface be called when scrolling like this:

public class ScrollChangeListenerScrollView extends HorizontalScrollView {


private MyScrollListener mMyScrollListener;

public ScrollChangeListenerScrollView(Context context) {
    super(context);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


public void setOnMyScrollListener(MyScrollListener myScrollListener){
    this.mMyScrollListener = myScrollListener;
}


@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if(mMyScrollListener!=null){
        mMyScrollListener.onScrollChange(this,l,t,oldl,oldt);
    }

}

public interface MyScrollListener {
    void onScrollChange(View view,int scrollX,int scrollY,int oldScrollX, int oldScrollY);
}

}

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;

A solution that actually works and covers all cases:

• Should use offsetBy not insetBy.
• Should also call the super function to get the original Rect.
• Bounds is faulty. you need to offset the original X, Y. Bounds have X, Y as zeros.
• Original x, y can be non-zero for instance when setting the leftView of the UITextField.

Sample:

override func textRect(forBounds bounds: CGRect) -> CGRect {
    return super.textRect(forBounds: bounds).offsetBy(dx: 0.0, dy: 4)
}


override func editingRect(forBounds bounds: CGRect) -> CGRect {
    return super.editingRect(forBounds: bounds).offsetBy(dx: 0.0, dy: 4)
}

To build upon @6twenty's answer...I prefer panTo(LatLng) over setCenter(LatLng) as panTo animates for smoother transition to center "if the change is less than both the width and height of the map". https://developers.google.com/maps/documentation/javascript/reference#Map

The below uses Google Maps API v3.

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(latitude, longitude),
    title: markerTitle,
    map: map,
});
google.maps.event.addListener(marker, 'click', function () {
    map.panTo(marker.getPosition());
    //map.setCenter(marker.getPosition()); // sets center without animation
});

Okay, I know I'm late to the party. But let me share with you what worked for me. The tabindex and z-index solutions did not work for me.

Setting the parent of the select element worked as per the common problems listed on select2 site.

Set java.library.path to a directory containing this DLL which Java uses to find native libraries. Specify -D switch on the command line

java -Djava.library.path=C:\Java\native\libs YourProgram

C:\Java\native\libs should contain sqljdbc_auth.dll

Look at this SO post if you are using Eclipse or at this blog if you want to set programatically.

If you have the luxury of working in C++, use this:

template<typename T>
void swapPrimitives(T& a, T& b)
{
    T c = a;
    a = b;
    b = c;
}

Granted, in the case of char*, it would only swap the pointers themselves, not the data they point to, but in most cases, that is OK, right?

In modern browsers, this has become a lot easier, thanks to the URLSearchParams interface. This defines a host of utility methods to work with the query string of a URL.

Assuming that our URL is https://example.com/?product=shirt&color=blue&newuser&size=m, you can grab the query string using window.location.search:

const queryString = window.location.search;
console.log(queryString);
// ?product=shirt&color=blue&newuser&size=m

You can then parse the query string’s parameters using URLSearchParams:

const urlParams = new URLSearchParams(queryString);

Then you can call any of its methods on the result.

For example, URLSearchParams.get() will return the first value associated with the given search parameter:

const product = urlParams.get('product')
console.log(product);
// shirt

const color = urlParams.get('color')
console.log(color);
// blue

const newUser = urlParams.get('newuser')
console.log(newUser);
// empty string

You can use URLSearchParams.has() to check whether a certain parameter exists:

console.log(urlParams.has('product'));
// true

console.log(urlParams.has('paymentmethod'));
// false

Try this:

$("#textbox").bind('paste',function() {alert("Change detected!");});

See demo on JSFiddle.

If INSERTS are rare, I would avoid doing a NOT EXISTS (...) since it emits a SELECT on all updates. Instead, take a look at wildpeaks answer: https://dba.stackexchange.com/questions/5815/how-can-i-insert-if-key-not-exist-with-postgresql

CREATE OR REPLACE FUNCTION upsert_tableName(arg1 type, arg2 type) RETURNS VOID AS $$ 
    DECLARE 
    BEGIN 
        UPDATE tableName SET col1 = value WHERE colX = arg1 and colY = arg2; 
        IF NOT FOUND THEN 
        INSERT INTO tableName values (value, arg1, arg2); 
        END IF; 
    END; 
    $$ LANGUAGE 'plpgsql'; 

This way Postgres will initially try to do a UPDATE. If no rows was affected, it will fall back to emitting an INSERT.

You could create a user form:

http://www.excel-vba-easy.com/vba-userform-excel-vba.html

// vanillaJS
function isJSON(str) {
    try {
        return (JSON.parse(str) && !!str);
    } catch (e) {
        return false;
    }
}

Usage: isJSON({}) will be false, isJSON('{}') will be true.

To check if something is an Array or Object (parsed JSON):

// vanillaJS
function isAO(val) {
    return val instanceof Array || val instanceof Object ? true : false;
}

// ES2015
var isAO = (val) => val instanceof Array || val instanceof Object ? true : false;

Usage: isAO({}) will be true, isAO('{}') will be false.

let string = " Test Trimmed String "

For Removing white Space and New line use below code :-

let str_trimmed = yourString.trimmingCharacters(in: .whitespacesAndNewlines)

For Removing only Spaces from string use below code :-

let str_trimmed = yourString.trimmingCharacters(in: .whitespaces)

The image needs to be in the same folder that your html page is in, then create a href to that folder with the picture name at the end. Example:

<img src="C:\users\home\pictures\picture.png"/>

Almost the same as Audrius cooked up some months ago, but you might find it a bit more readable with the defaults in the function head - the way you are used to with python:

@app.route('/<user_id>')
@app.route('/<user_id>/<username>')
def show(user_id, username='Anonymous'):
    return user_id + ':' + username

No. It makes no sense to order the records before grouping, since grouping is going to mutate the result set. The subquery way is the preferred way. If this is going too slow you would have to change your table design, for example by storing the id of of the last post for each author in a seperate table, or introduce a boolean column indicating for each author which of his post is the last one.

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

Generically, do/while is good for any sort of loop construct where one must execute the loop at least once. It is possible to emulate this sort of looping through either a straight while or even a for loop, but often the result is a little less elegant. I'll admit that specific applications of this pattern are fairly rare, but they do exist. One which springs to mind is a menu-based console application:

do {
    char c = read_input();

    process_input(c);
} while (c != 'Q');

Here's a Swift 3.2+ alternative that avoids unnecessary string manipulation. In this case, the maximum length is 10:

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    let text = textField.text ?? ""

    return text.count - range.length + string.count <= 10
}

Below you can find my implementation of gradient descent for linear regression problem.

At first, you calculate gradient like X.T * (X * w - y) / N and update your current theta with this gradient simultaneously.

• X: feature matrix
• y: target values
• w: weights/values
• N: size of training set

Here is the python code:

import pandas as pd
import numpy as np
from matplotlib import pyplot as plt
import random

def generateSample(N, variance=100):
    X = np.matrix(range(N)).T + 1
    Y = np.matrix([random.random() * variance + i * 10 + 900 for i in range(len(X))]).T
    return X, Y

def fitModel_gradient(x, y):
    N = len(x)
    w = np.zeros((x.shape[1], 1))
    eta = 0.0001

    maxIteration = 100000
    for i in range(maxIteration):
        error = x * w - y
        gradient = x.T * error / N
        w = w - eta * gradient
    return w

def plotModel(x, y, w):
    plt.plot(x[:,1], y, "x")
    plt.plot(x[:,1], x * w, "r-")
    plt.show()

def test(N, variance, modelFunction):
    X, Y = generateSample(N, variance)
    X = np.hstack([np.matrix(np.ones(len(X))).T, X])
    w = modelFunction(X, Y)
    plotModel(X, Y, w)


test(50, 600, fitModel_gradient)
test(50, 1000, fitModel_gradient)
test(100, 200, fitModel_gradient)

For me the code:

<form (submit)="addTodo()">_x000D_
  <input type="text" [(ngModel)]="text">_x000D_
</form>

throws error, but I added name attribute to input:

<form (submit)="addTodo()">_x000D_
  <input type="text" [(ngModel)]="text" name="text">_x000D_
</form>

and it started to work.

I would suggest following design : Item Table: Itemid, taglist1, taglist2
this will be fast and make easy saving and retrieving the data at item level.

In parallel build another table: Tags tag do not make tag unique identifier and if you run out of space in 2nd column which contains lets say 100 items create another row.

Now while searching for items for a tag it will be super fast.

iOS 8 has changed notification registration in a non-backwards compatible way. While you need to support iOS 7 and 8 (and while apps built with the 8 SDK aren't accepted), you can check for the selectors you need and conditionally call them correctly for the running version.

Here's a category on UIApplication that will hide this logic behind a clean interface for you that will work in both Xcode 5 and Xcode 6.

Header:

//Call these from your application code for both iOS 7 and 8
//put this in the public header
@interface UIApplication (RemoteNotifications)

- (BOOL)pushNotificationsEnabled;
- (void)registerForPushNotifications;

@end

Implementation:

//these declarations are to quiet the compiler when using 7.x SDK
//put this interface in the implementation file of this category, so they are
//not visible to any other code.
@interface NSObject (IOS8)

- (BOOL)isRegisteredForRemoteNotifications;
- (void)registerForRemoteNotifications;

+ (id)settingsForTypes:(NSUInteger)types categories:(NSSet*)categories;
- (void)registerUserNotificationSettings:(id)settings;

@end

@implementation UIApplication (RemoteNotifications)

- (BOOL)pushNotificationsEnabled
{
    if ([self respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
    {
        return [self isRegisteredForRemoteNotifications];
    }
    else
    {
        return ([self enabledRemoteNotificationTypes] & UIRemoteNotificationTypeAlert);
    }
}

- (void)registerForPushNotifications
{
    if ([self respondsToSelector:@selector(registerForRemoteNotifications)])
    {
        [self registerForRemoteNotifications];

        Class uiUserNotificationSettings = NSClassFromString(@"UIUserNotificationSettings");

        //If you want to add other capabilities than just banner alerts, you'll need to grab their declarations from the iOS 8 SDK and define them in the same way.
        NSUInteger UIUserNotificationTypeAlert   = 1 << 2;

        id settings = [uiUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert categories:[NSSet set]];            
        [self registerUserNotificationSettings:settings];

    }
    else
    {
        [self registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert];
    }
}

Static classes should be able to do this so they can be used generically. I had to instead implement a Singleton to achieve the desired results.

I had a bunch of Static Business Layer classes that implemented CRUD methods like "Create", "Read", "Update", "Delete" for each entity type like "User", "Team", ect.. Then I created a base control that had an abstract property for the Business Layer class that implemented the CRUD methods. This allowed me to automate the "Create", "Read", "Update", "Delete" operations from the base class. I had to use a Singleton because of the Static limitation.

I made some changes for backspace

        string pass = "";
        Console.Write("Enter your password: ");
        ConsoleKeyInfo key;

        do
        {
            key = Console.ReadKey(true);

            // Backspace Should Not Work
            if (key.Key != ConsoleKey.Backspace)
            {
                pass += key.KeyChar;
                Console.Write("*");
            }
            else
            {
                pass = pass.Remove(pass.Length - 1);
                Console.Write("\b \b");
            }
        }
        // Stops Receving Keys Once Enter is Pressed
        while (key.Key != ConsoleKey.Enter);

        Console.WriteLine();
        Console.WriteLine("The Password You entered is : " + pass);

String[] w = {"a", "b", "c", "d", "e"};  

List<String> wL = Arrays.asList(w);  

If you have the test binary installed or ksh has a matching built-in function, you could use it to perform your checks. Usually /bin/[ is a symbolic link to test:

if [ -e "$file_name" ]; then
  echo "File exists"
fi

if [ -z "$used_var" ]; then
  echo "Variable is empty"
fi

The problem is that your REGX pattern will only match the input "0-9".

To meet your requirement (0-9999999), you should rewrite your regx pattern:

ng-pattern="/^[0-9]{1,7}$/"

My example:

HTML:

<div ng-app ng-controller="formCtrl">
  <form name="myForm" ng-submit="onSubmit()">
    <input type="number" ng-model="price" name="price_field" 
           ng-pattern="/^[0-9]{1,7}$/" required>
    <span ng-show="myForm.price_field.$error.pattern">Not a valid number!</span>
    <span ng-show="myForm.price_field.$error.required">This field is required!</span>
    <input type="submit" value="submit"/>
  </form>
</div>

JS:

function formCtrl($scope){
  $scope.onSubmit = function(){
    alert("form submitted");
  }
}

Here is a jsFiddle demo.

You just can't return the value directly because it is an async call. An async call means it is running in the background (actually scheduled for later execution) while your code continues to execute.

You also can't have such code in the class directly. It needs to be moved into a method or the constructor.

What you can do is not to subscribe() directly but use an operator like map()

export class DataComponent{
    someMethod() {
      return this.http.get(path).map(res => {
        return res.json();
      });
    }
}

In addition, you can combine multiple .map with the same Observables as sometimes this improves code clarity and keeps things separate. Example:

validateResponse = (response) => validate(response);

parseJson = (json) => JSON.parse(json);

fetchUnits() {
    return this.http.get(requestUrl).map(this.validateResponse).map(this.parseJson);
}

This way an observable will be return the caller can subscribe to

export class DataComponent{
    someMethod() {
      return this.http.get(path).map(res => {
        return res.json();
      });
    }

    otherMethod() {
      this.someMethod().subscribe(data => this.data = data);
    }
}

The caller can also be in another class. Here it's just for brevity.

data => this.data = data

and

res => return res.json()

are arrow functions. They are similar to normal functions. These functions are passed to subscribe(...) or map(...) to be called from the observable when data arrives from the response. This is why data can't be returned directly, because when someMethod() is completed, the data wasn't received yet.

Using the .loc[] accessor:

In [25]: a.loc[a['c1'] == 8].index[0]
Out[25]: 4

Can also use the get_loc() by setting 'c1' as the index. This will not change the original dataframe.

In [17]: a.set_index('c1').index.get_loc(8)
Out[17]: 4

This exception only happens if you are parsing an empty String/empty byte array.

below is a snippet on how to reproduce it:

String xml = ""; // <-- deliberately an empty string.
ByteArrayInputStream xmlStream = new java.io.ByteArrayInputStream(xml.getBytes());
Unmarshaller u = JAXBContext.newInstance(...)
u.setSchema(...);
u.unmarshal( xmlStream ); // <-- here it will fail

For Java 12 onwards, official General-Availability (GA) and Early-Access (EA) Windows 64-bit builds of the OpenJDK (GPL2 + Classpath Exception) from Oracle are available as tar.gz/zip from the JDK website.

If you prefer an installer, there are several distributions. There is a public Google Doc and Blog post by the Java Champions community which lists the best-supported OpenJDK distributions. Currently, these are:

• AdoptOpenJDK, which also has a version with OpenJ9 instead of Hotspot as its VM (backed by IBM and jClarity)
• Amazon Corretto
• Liberica from Bellsoft
• Red Hat OpenJDK
• SAPMachine (backed by SAP)
• Zulu Community (backed by Azul Systems)

This seems to be working for a little rigidly geometrically set app where it needs to run on both mobile and other browsers with little change, so finding the mobile/non-mobile browser status and for mobiles setting the viewport to device-width is needed. As scripts can be run from the header, the below js in header seems to change the metatag for device-width Before the page loads. One might note that the use of navigator.userAgent is stipulated as experimental. The script must follow the metatag entry to be changed, so one must choose some initial content, and then change on some condition.

<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script>  
  var userAgentHeader = navigator.userAgent ; 
  var browserIsMobileOrNot = "mobileNOT" ; 
  if( userAgentHeader.includes( "Mobi" ) ) { 
    browserIsMobileOrNot = "mobileYES" ; 
    //document.querySelector('meta[name="viewport"]').setAttribute( "content", "width=device-width, initial-scale=1.0" );
  } else { 
    browserIsMobileOrNot = "mobileNOT" ;  
    document.querySelector('meta[name="viewport"]').setAttribute( "content", "");
  }
</script>

Infact, 2 dimensional array is the list of list of X, where X is one of your data structures from typical ones to user-defined ones. As the following snapshot code, I added row by row into an array triangle. To create each row, I used the method add to add elements manually or the method asList to create a list from a band of data.

package algorithms;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class RunDemo {

/**
 * @param args
 */
public static void main(String[] args) {
    // Get n
    List<List<Integer>> triangle = new ArrayList<List<Integer>>();

    List<Integer> row1 = new ArrayList<Integer>(1);
    row1.add(2);
    triangle.add(row1);

    List<Integer> row2 = new ArrayList<Integer>(2);
    row2.add(3);row2.add(4);
    triangle.add(row2);

    triangle.add(Arrays.asList(6,5,7));
    triangle.add(Arrays.asList(4,1,8,3));

    System.out.println("Size = "+ triangle.size());
    for (int i=0; i<triangle.size();i++)
        System.out.println(triangle.get(i));

}
}

Running the sample, it generates the output:

Size = 4
[2]
[3, 4]
[6, 5, 7]
[4, 1, 8, 3]

You would simply need to do this in your onClick:

AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Alert");
alertDialog.setMessage("Alert message to be shown");
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
alertDialog.show();

I don't know from where you saw that you need DialogFragment for simply showing an alert.

Hope this helps.

Due to PermGen removal some options were removed (like -XX:MaxPermSize), but options -Xms and -Xmx work in Java 8. It's possible that under Java 8 your application simply needs somewhat more memory. Try to increase -Xmx value. Alternatively you can try to switch to G1 garbage collector using -XX:+UseG1GC.

Note that if you use any option which was removed in Java 8, you will see a warning upon application start:

$ java -XX:MaxPermSize=128M -version
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128M; support was removed in 8.0
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

I resolve the issue by restarting Docker.

Another one-liner, without counting hyper-threaded cores:

lscpu | awk -F ":" '/Core/ { c=$2; }; /Socket/ { print c*$2 }' 

I had this issue while working at the local Starbucks and I remembered that when I initially set up my database through Mongo Atlas. I set my IP address to be able to access the database. After looking through several threads, I changed my IP address on Atlas and the issue went away. Hope this helps someone.

Try this:

@Html.ActionLink("DisplayText", "Action", "Controller", route, attribute)

in your code should be,

@Html.ActionLink("Search", "List", "Search", new{@class="btn btn-info", @id="addressSearch"})

Use this CSS (jsFiddle example):

input:disabled.btn:hover,
input:disabled.btn:active,
input:disabled.btn:focus {
  color: green
}

You have to write the most outer element on the left and the most inner element on the right.

.btn:hover input:disabled would select any disabled input elements contained in an element with a class btn which is currently hovered by the user.

I would prefer :disabled over [disabled], see this question for a discussion: Should I use CSS :disabled pseudo-class or [disabled] attribute selector or is it a matter of opinion?

By the way, Laravel (PHP) generates the HTML - not the browser.

The online documentation seems a little unclear, so I just performed a little test. Choosing to break on Thrown from the Exceptions dialog box causes the program execution to break on any exception, handled or unhandled. If you want to break on handled exceptions only, it seems your only recourse is to go through your code and put breakpoints on all your handled exceptions. This seems a little excessive, so it might be better to add a debug statement whenever you handle an exception. Then when you see that output, you can set a breakpoint at that line in the code.

I have redesigned the code for phone numbers +9 (987) 124124 Extract digits from a string in Java

 public static String stripNonDigitsV2( CharSequence input ) {
    if (input == null)
        return null;
    if ( input.length() == 0 )
        return "";

    char[] result = new char[input.length()];
    int cursor = 0;
    CharBuffer buffer = CharBuffer.wrap( input );
    int i=0;
    while ( i< buffer.length()  ) { //buffer.hasRemaining()
        char chr = buffer.get(i);
        if (chr=='u'){
            i=i+5;
            chr=buffer.get(i);
        }

        if ( chr > 39 && chr < 58 )
            result[cursor++] = chr;
        i=i+1;
    }

    return new String( result, 0, cursor );
}

I do this quite a bit and thought I could add a simpler answer. I set it up as a simple class here, but I run this every evening to collect financial data on companies I'm following.

class WebPage
{
    public static string Get(string uri)
    {
        string results = "N/A";

        try
        {
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(uri);
            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();

            StreamReader sr = new StreamReader(resp.GetResponseStream());
            results = sr.ReadToEnd();
            sr.Close();
        }
        catch (Exception ex)
        {
            results = ex.Message;
        }
        return results;
    }
}

In this case I pass in a url and it returns the page as HTML. If you want to do something different with the stream instead you can easily change this.

You use it like this:

string page = WebPage.Get("http://finance.yahoo.com/q?s=yhoo");

After reading all the issues with the added functions I decided I need something more accurate. Here's what I came up with that works for me.

If you need to specifically validate hostnames (they must start and end with an alphanumberic character and contain only alphanumerics and hyphens) this function should be enough.

function is_valid_domain($domain) {
    // Check for starting and ending hyphen(s)
    if(preg_match('/-./', $domain) || substr($domain, 1) == '-') {
        return false;
    }

    // Detect and convert international UTF-8 domain names to IDNA ASCII form
    if(mb_detect_encoding($domain) != "ASCII") {
        $idn_dom = idn_to_ascii($domain);
    } else {
        $idn_dom = $domain;
    }

    // Validate
    if(filter_var($idn_dom, FILTER_VALIDATE_DOMAIN, FILTER_FLAG_HOSTNAME) != false) {
        return true;
    }
    return false;
}

Note that this function will work on most (haven't tested all languages) LTR languages. It will not work on RTL languages.

is_valid_domain('a');                                                                       Y

The @ symbol when specifying HtmlAttributes is used when the "thing" you are trying to set is a keyword c#. So for instance the word class, you cannot specify class, you must use @class.

Additional answer for Visual Studio 2012:

You can open .dtsx along with their corresponding .dtproj project files with the SQL Server Data Tools Business Intelligence (SSDT-BI) add-in:

http://blogs.msdn.com/b/mattm/archive/2013/03/07/sql-server-data-tools-business-intelligence-for-visual-studio-2012-released-online.aspx

http://www.microsoft.com/download/details.aspx?id=36843

If the projects were created with an earlier version they will require an upgrade.

I did have some hang ups installing this - the install would spin on "Install_VSTA2012_CPU32_Action" and similar steps. It wasn't until I did a repair inside of the same installer did it install completely.

There is no built-in functionality in VBS for that, however, you can use the FileSystemObject FileExists function for that :

Option Explicit
DIM fso    
Set fso = CreateObject("Scripting.FileSystemObject")

If (fso.FileExists("C:\Program Files\conf")) Then
  WScript.Echo("File exists!")
  WScript.Quit()
Else
  WScript.Echo("File does not exist!")
End If

WScript.Quit()

If you have many cases and do not want to write a ton of strcmp() calls, you could do something like:

switch(my_hash_function(the_string)) {
    case HASH_B1: ...
    /* ...etc... */
}

You just have to make sure your hash function has no collisions inside the set of possible values for the string.

"complete" executes when the ajax call is finished. "success" executes when the ajax call finishes with a successful response code.

that should do the job done:

    $(':checkbox').each(function() {
        this.checked = true;                        
    });

I would use SharedSizeGroup

<Grid>
    <Grid.ColumnDefinition>
        <ColumnDefinition SharedSizeGroup="col1"></ColumnDefinition>  
        <ColumnDefinition SharedSizeGroup="col2"></ColumnDefinition>
    </Grid.ColumnDefinition>
    <TextBox Background="Azure" Text="Hello" Grid.Column="1" MaxWidth="200" />
</Grid>

To add one day to a date object:

var date = new Date();

// add a day
date.setDate(date.getDate() + 1);

I know it is an old thread, but I'd like to put my 2 cents based on the answer by @Pawel Miech.

It is true that you need to convert the difference into milliseconds, then you need to make some math. But notice that, you need to do the math in backward manner, i.e. you need to calculate years, months, days, hours then minutes.

I used to do some thing like this:

    var mins;
    var hours;
    var days;
    var months;
    var years;

    var diff = new Date() - new Date(yourOldDate);  
// yourOldDate may be is coming from DB, for example, but it should be in the correct format ("MM/dd/yyyy hh:mm:ss:fff tt")

    years = Math.floor((diff) / (1000 * 60 * 60 * 24 * 365));
    diff = Math.floor((diff) % (1000 * 60 * 60 * 24 * 365));
    months = Math.floor((diff) / (1000 * 60 * 60 * 24 * 30));
    diff = Math.floor((diff) % (1000 * 60 * 60 * 24 * 30));
    days = Math.floor((diff) / (1000 * 60 * 60 * 24));
    diff = Math.floor((diff) % (1000 * 60 * 60 * 24));
    hours = Math.floor((diff) / (1000 * 60 * 60));
    diff = Math.floor((diff) % (1000 * 60 * 60));
    mins = Math.floor((diff) / (1000 * 60));

But, of course, this is not precise because it assumes that all years have 365 days and all months have 30 days, which is not true in all cases.

I'll suggest that you use this as it will check for both single and multiple occurrence of white space (as suggested by Lucas Green).

$journalName = preg_replace('/\s+/', '_', $journalName);

instead of:

$journalName = str_replace(' ', '_', $journalName);

You should set z-index to absolutely positioned div that is greater than to relative div.

Something like that

<div style="position: relative; width:600px; z-index: 10;">
    <p>Content of unknown length</p>
    <div>Content of unknown height</div>
    <div class="btn" style="position: absolute; right: 0; bottom: 0; width: 200px; height: 100px; z-index: 20;"></div>
</div>

z-index sets layers positioning in depth of page.

Or you may use floating to show all text of unkown length. But in this case you could not absolutely position your div

<div style="position: relative; width:600px;">
  <div class="btn" style="float: right; width: 200px; height: 100px;"></div>
  <p>Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length Content of unknown length</p>
  <div>Content of unknown height</div>
  <div class="btn" style="position: absolute; right: 0; bottom: 0; width: 200px; height: 100px;"></div>
</div>?

There is no such thing. It looks like you want something like "here documents" in Perl and the shells, but Python doesn't have that.

Using raw strings or multiline strings only means that there are fewer things to worry about. If you use a raw string then you still have to work around a terminal "\" and with any string solution you'll have to worry about the closing ", ', ''' or """ if it is included in your data.

That is, there's no way to have the string

 '   ''' """  " \

properly stored in any Python string literal without internal escaping of some sort.

Maybe this is useful to anyone in the future, I have implemented a custom Authorize Attribute like this:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class ClaimAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
    private readonly string _claim;

    public ClaimAuthorizeAttribute(string Claim)
    {
        _claim = Claim;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var user = context.HttpContext.User;
        if(user.Identity.IsAuthenticated && user.HasClaim(ClaimTypes.Name, _claim))
        {
            return;
        }

        context.Result = new ForbidResult();
    }
}

cur.execute( "SELECT * FROM records WHERE email LIKE %s", (search,) )

I do not why, but this works for me . rather than use '%s'.

You could try..

comm -13 <(sort file1) <(sort file2) > file3

or

grep -Fxvf file1 file2 > file3

or

diff file1 file2 | grep "<" | sed 's/^<//g'  > file3

or

join -v 2 <(sort file1) <(sort file2) > file3

A little gem in the discussion above - thanks to @Codest and @Kevin Pullin. In TortoiseHg, there's a dropdown option adjacent to the commit button. Selecting "Amend current revision" brings back the comment and the list of files. SO useful.

class Toggle extends React.Component {
  state = {
    show: true,
  }

  render() {
    const {show} = this.state;
    return (
      <div>
        <button onClick={()=> this.setState({show: !show })}>
          toggle: {show ? 'show' : 'hide'}
        </button>    
        {show && <div>Hi there</div>}
      </div>
     );
  }
}

Should you want to resort to using a plug-in, malihu-custom-scrollbar-plugin, could do the job. It performs an actual scroll, not just a jump. You can even specify the speed/momentum of scroll. It also lets you set up a menu (list of links to scroll to), which have their CSS changed based on whether the anchors-to-scroll-to are in viewport, and other useful features.

There are demo on the author's site and let our company site serve as a real-world example too.

I have a solution which works well but instead an ellipsis it uses a gradient. It works when you have dynamic text so you don't know if it will be long enough to need an ellipse. The advantages are that you don't have to do any JavaScript calculations and it works for variable width containers including table cells and is cross-browser. It uses a couple of extra divs, but it's very easy to implement.

Markup:

<td>
    <div class="fade-container" title="content goes here">
         content goes here
         <div class="fade">
    </div>
</td>

CSS:

.fade-container { /*two lines*/
    overflow: hidden;
    position: relative;
    line-height: 18px; 
    /* height must be a multiple of line-height for how many rows you want to show (height = line-height x rows) */
    height: 36px;
    -ms-hyphens: auto;
    -webkit-hyphens: auto;
    hyphens: auto;
    word-wrap: break-word;
}

.fade {
        position: absolute;
        top: 50%;/* only cover the last line. If this wrapped to 3 lines it would be 33% or the height of one line */
        right: 0;
        bottom: 0;
        width: 26px;
        background: linear-gradient(to right,  rgba(255,255,255,0) 0%,rgba(255,255,255,1) 100%);
}

You can use npm uninstall <package-name> will remove it from your package.json file and from node_modules.

If you do ng help command, you will see that there is no ng remove/delete supported command. So, basically you cannot revert the ng add behavior yet.

If you want to switch to a specific database on startup, try

/Applications/Postgres.app/Contents/Versions/9.5/bin/psql vigneshdb;

By default, Postgres runs on the port 5432. If it runs on another, make sure to pass the port in the command line.

/Applications/Postgres.app/Contents/Versions/9.5/bin/psql -p2345 vigneshdb;

By a simple alias, we can make it handy.

Create an alias in your .bashrc or .bash_profile

function psql()
{
    db=vigneshdb
    if [ "$1" != ""]; then
            db=$1
    fi
    /Applications/Postgres.app/Contents/Versions/9.5/bin/psql -p5432 $1
}

Run psql in command line, it will switch to default database; psql anotherdb, it will switch to the db with the name in argument, on startup.

You are returning char, and not char*, which is the pointer to the first character of an array.

If you want to return a new character array instead of doing in-place modification, you can ask for an already allocated pointer (char*) as parameter or an uninitialized pointer. In this last case you must allocate the proper number of characters for new string and remember that in C parameters as passed by value ALWAYS, so you must use char** as parameter in the case of array allocated internally by function. Of course, the caller must free that pointer later.

This does not strictly answer the original question but some people have mentioned that with session.autoflush = True you don't have to use session.flush()... And this is not always true.

If you want to use the id of a newly created object in the middle of a transaction, you must call session.flush().

# Given a model with at least this id
class AModel(Base):
   id = Column(Integer, primary_key=True)  # autoincrement by default on integer primary key

session.autoflush = True

a = AModel()
session.add(a)
a.id  # None
session.flush()
a.id  # autoincremented integer

This is because autoflush does NOT auto fill the id (although a query of the object will, which sometimes can cause confusion as in "why this works here but not there?" But snapshoe already covered this part).

One related aspect that seems pretty important to me and wasn't really mentioned:

Why would you not commit all the time? - The answer is atomicity.

A fancy word to say: an ensemble of operations have to all be executed successfully OR none of them will take effect.

For example, if you want to create/update/delete some object (A) and then create/update/delete another (B), but if (B) fails you want to revert (A). This means those 2 operations are atomic.

Therefore, if (B) needs a result of (A), you want to call flush after (A) and commit after (B).

Also, if session.autoflush is True, except for the case that I mentioned above or others in Jimbo's answer, you will not need to call flush manually.

function capitalize(s){
    return s.toLowerCase().replace( /\b./g, function(a){ return a.toUpperCase(); } );
};

capitalize('this IS THE wOrst string eVeR');

output: "This Is The Worst String Ever"

Update:

It appears this solution supersedes mine: https://stackoverflow.com/a/7592235/104380

if you want the queries to be logged to mongodb log file, you have to set both the log level and the profiling, like for example:

db.setLogLevel(1)
db.setProfilingLevel(2)

(see https://docs.mongodb.com/manual/reference/method/db.setLogLevel)

Setting only the profiling would not have the queries logged to file, so you can only get it from

db.system.profile.find().pretty()

On windows and Netbeans you can set the relative path as:

    new FileReader("src\\PACKAGE_NAME\\FILENAME");

On Linux and Netbeans you can set the relative path as:

    new FileReader("src/PACKAGE_NAME/FILENAME");

If you have your code inside Source Packages I do not know if it is the same for eclipse or other IDE

At the command line paste the following

export QUERY_STRING="param1=abc&param2=xyz" ;  
POST_STRING="name=John&lastname=Doe" ; php -e -r 
'parse_str($_SERVER["QUERY_STRING"], $_GET); parse_str($_SERVER["POST_STRING"], 
$_POST);  include "index.php";'

Deactivating Breakpoints caused the new script to load for me.

It might just be a connection string error, which is solved by the above process, but if you are using the dll's in multiple projects then making sure the connection string is named properly will fix the error for sure.

This page gives a decent breakdown of the different join types, as well as venn diagram visualizations to help... well... visualize the difference in the joins.

As the comments said this is a quite basic query from the sounds of it, so you should try to understand the differences between the joins and what they actually mean.

Check out http://blog.codinghorror.com/a-visual-explanation-of-sql-joins/

You're looking for a query such as:

DECLARE @table1 TABLE (test int)
DECLARE @table2 TABLE (test int)

INSERT INTO @table1
(
    test
)
SELECT 1
UNION ALL SELECT 2

INSERT INTO @table2
(
    test
)
SELECT 1
UNION ALL SELECT 3

-- Here's the important part
SELECT  a.*
FROM    @table1 a
LEFT    join @table2 b on a.test = b.test -- this will return all rows from a
WHERE   b.test IS null -- this then excludes that which exist in both a and b

-- Returned results:

Don't use userForm = new FormGroup()

Use form = new FormGroup() instead.

And in the form use <form [formGroup]="form"> ...</form>. It works for me with angular 6

This answer follows on to owlstead and Mat's responses. It applies to SE/EE installations, not ME/mobile/Android SSL.

Since no one has yet mentioned it, I'll mention the "production way" to fix this: Follow the steps from the AuthSSLProtocolSocketFactory class in HttpClient to update your trust store & key stores.

1. Import a trusted certificate and generate a truststore file

keytool -import -alias "my server cert" -file server.crt -keystore my.truststore

2. Generate a new key (use the same password as the truststore)

keytool -genkey -v -alias "my client key" -validity 365 -keystore my.keystore

3. Issue a certificate signing request (CSR)

keytool -certreq -alias "my client key" -file mycertreq.csr -keystore my.keystore

4. (self-sign or get your cert signed)

5. Import the trusted CA root certificate

keytool -import -alias "my trusted ca" -file caroot.crt -keystore my.keystore

6. Import the PKCS#7 file containg the complete certificate chain

keytool -import -alias "my client key" -file mycert.p7 -keystore my.keystore

7. Verify the resultant keystore file's contents

keytool -list -v -keystore my.keystore

If you don't have a server certificate, generate one in JKS format, then export it as a CRT file. Source: keytool documentation

keytool -genkey -alias server-alias -keyalg RSA -keypass changeit
    -storepass changeit -keystore my.keystore

keytool -export -alias server-alias -storepass changeit
    -file server.crt -keystore my.keystore

You could try Mobilenium (https://github.com/rafpyprog/Mobilenium), a python package that binds BrowserMob Proxy and Selenium.

An usage example:

>>> from mobilenium import mobidriver
>>>
>>> browsermob_path = 'path/to/browsermob-proxy'
>>> mob = mobidriver.Firefox(browsermob_binary=browsermob_path)
>>> mob.get('http://python-requests.org')
301
>>> mob.response['redirectURL']
'http://docs.python-requests.org'
>>> mob.headers['Content-Type']
'application/json; charset=utf8'
>>> mob.title
'Requests: HTTP for Humans \u2014 Requests 2.13.0 documentation'
>>> mob.find_elements_by_tag_name('strong')[1].text
'Behold, the power of Requests'

Pickle uses different protocols to convert your data to a binary stream.

• In python 2 there are 3 different protocols (0, 1, 2) and the default is 0.

• In python 3 there are 5 different protocols (0, 1, 2, 3, 4) and the default is 3.

You must specify in python 3 a protocol lower than 3 in order to be able to load the data in python 2. You can specify the protocol parameter when invoking pickle.dump.

I was able to make this work by creating a named range in the current sheet that referred to the table I wanted to reference in the other sheet.

In Entity Framework Core 2.1 we can use Query Types as Yuriy N suggested.

A more detailed article on how to use them can be found here

The most straight forward approach according to the article's examples would be:

1.We have for example the following entity Models to manage publications

public class Magazine
{
  public int MagazineId { get; set; }
  public string Name { get; set; }
  public string Publisher { get; set; }
  public List<Article> Articles { get; set; }
}

public class Article
{
  public int ArticleId { get; set; }
  public string Title { get; set; }
  public int MagazineId { get; set; }
  public DateTime PublishDate { get;  set; }
  public Author Author { get; set; }
  public int AuthorId { get; set; }
}
public class Author
{
  public int AuthorId { get; set; }
  public string Name { get; set; }
  public List<Article> Articles { get; set; }
}

2.We have a view called AuthorArticleCounts, defined to return the name and number of articles an author has written

SELECT
  a.AuthorName,
  Count(r.ArticleId) as ArticleCount
from Authors a
  JOIN Articles r on r.AuthorId = a.AuthorId
GROUP BY a.AuthorName

3.We go and create a model to be used for the View

public class AuthorArticleCount
{
  public string AuthorName { get; private set; }
  public int ArticleCount { get; private set; }
}

4.We create after that a DbQuery property in my DbContext to consume the view results inside the Model

public DbQuery<AuthorArticleCount> AuthorArticleCounts{get;set;}

4.1. You might need to override OnModelCreating() and set up the View especially if you have different view name than your Class.

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Query<AuthorArticleCount>().ToView("AuthorArticleCount");
}

5.Finally we can easily get the results of the View like this.

var results=_context.AuthorArticleCounts.ToList();

UPDATE According to ssougnez's comment

It's worth noting that DbQuery won't be/is not supported anymore in EF Core 3.0. See here

According to the documentation, just like with any css selector, you can specify as many conditions as you want, and they are treated as logical 'OR'.

This example returns a list of all div elements within the document with a class of either "note" or "alert":

var matches = document.querySelectorAll("div.note, div.alert");

source: https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll

Meanwhile to get the 'AND' functionality you can for example simply use a multiattribute selector, as jquery says:

https://api.jquery.com/multiple-attribute-selector/

ex. "input[id][name$='man']" specifies both id and name of the element and both conditions must be met. For classes it's as obvious as ".class1.class2" to require object of 2 classes.

All possible combinations of both are valid, so you can easily get equivalent of more sophisticated 'OR' and 'AND' expressions.

This is very old, but given a lot of experiences I have had with dates, you might want to consider this: People use different regional settings, as such, some people (and some databases/computers, depending on regional settings) may read this date 11/12/2016 as 11th Dec 2016 or Nov 12, 2016. Even more, 16/11/12 supplied to MySQL database will be internally converted to 12 Nov 2016, while Access database running on a UK regional setting computer will interpret and store it as 16th Nov 2012.

Therefore, I made it my policy to be explicit whenever I am going to interact with dates and databases. So I always supply my queries and programming codes as follows:

SELECT FirstName FROM Students WHERE DoB >= '11 Dec 2016';

Note also that Access will accept the #, thus:

SELECT FirstName FROM Students WHERE DoB >= #11 Dec 2016#;

but MS SQL server will not, so I always use " ' " as above, which both databases accept.

And when getting that date from a variable in code, I always convert the result to string as follows:

"SELECT FirstName FROM Students WHERE DoB >= " & myDate.ToString("d MMM yyyy")

I am writing this because I know sometimes some programmers may not be keen enough to detect the inherent conversion. There will be no error for dates < 13, just different results!

As for the question asked, add one day to the last date and make the comparison as follows:

dated >= '11 Nov 2016' AND dated < '15 Nov 2016' 

I had the same issue and I found this.

On the url, it requires the server key in the end and not the api key for the app.

So Basically, you just add the server key in the end of the URL like this:

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=yourlatitude,yourlongitude&radius=5000&sensor=true&key=SERVERKEY

Now, to obtain the server key, just follow these steps:

1) Go to Developer Console https://code.google.com/apis/console/

2) In the Credentials, under Public API Access, Create New key

3) Select the server key from the option.

4) Enter your IP Address on the field and if you have more ip addresses, you can just add on every single line.NOTE: Enter the IP Address only when you want to use it for your testing purpose. Else leave the IP Address section blank.

5) Once you are done, click create and your new Server Key will be generated and you can then add that server key to your URL.

Last thing is that, instead of putting the sensor=true in the middle of the URL, you can add it in the end like this:

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=yourlatitude,yourlongitude&radius=5000&key=SERVERKEY&sensor=true

This will definitely solve the issue and just remember to use the server key for Places API.

EDIT

I believe the web URL has changed in the past years. You can access developers console from here now - https://console.developers.google.com/apis/dashboard

• Navigate to developers console - https://console.developers.google.com/ or use the link from details to navigate directly to API dashboard.
• Under developer console, find Label from the left navigation panel
• Select project
• Choose Credentials from the left Navigation panel
• You could create credentials type from the Top nav bar as required.

Hope this answer will help you and other viewers. Good Luck .. :)

When you are developing an SDK. You need some extra operation.

1) create Localizable.strings as usual in YourLocalizeDemoSDK.

2) create the same Localizable.strings in YourLocalizeDemo.

3) find your Bundle Path of YourLocalizeDemoSDK.

Swift4:

// if you use NSLocalizeString in NSObject, you can use it like this
let value = NSLocalizedString("key", tableName: nil, bundle: Bundle(for: type(of: self)), value: "", comment: "")

Bundle(for: type(of: self)) helps you to find the bundle in YourLocalizeDemoSDK. If you use Bundle.main instead, you will get a wrong value(in fact it will be the same string with the key).

But if you want to use the String extension mentioned by dr OX. You need to do some more. The origin extension looks like this.

extension String {
    var localized: String {
        return NSLocalizedString(self, tableName: nil, bundle: Bundle.main, value: "", comment: "")
    }
}

As we know, we are developing an SDK, Bundle.main will get the bundle of YourLocalizeDemo's bundle. That's not what we want. We need the bundle in YourLocalizeDemoSDK. This is a trick to find it quickly.

Run the code below in a NSObject instance in YourLocalizeDemoSDK. And you will get the URL of YourLocalizeDemoSDK.

let bundleURLOfSDK = Bundle(for: type(of: self)).bundleURL
let mainBundleURL = Bundle.main.bundleURL

Print both of the two url, you will find that we can build bundleURLofSDK base on mainBundleURL. In this case, it will be:

let bundle = Bundle(url: Bundle.main.bundleURL.appendingPathComponent("Frameworks").appendingPathComponent("YourLocalizeDemoSDK.framework")) ?? Bundle.main

And the String extension will be:

extension String {
    var localized: String {
        let bundle = Bundle(url: Bundle.main.bundleURL.appendingPathComponent("Frameworks").appendingPathComponent("YourLocalizeDemoSDK.framework")) ?? Bundle.main
        return NSLocalizedString(self, tableName: nil, bundle: bundle, value: "", comment: "")
    }
}

Hope it helps.

Yes. The sorted built-in accepts a key argument:

sorted(li,key=lambda x: x[1])
Out[31]: [['Jason', 1], ['John', 2], ['Jim', 9]]

note that sorted returns a new list. If you want to sort in-place, use the .sort method of your list (which also, conveniently, accepts a key argument).

or alternatively,

from operator import itemgetter
sorted(li,key=itemgetter(1))
Out[33]: [['Jason', 1], ['John', 2], ['Jim', 9]]

Read more on the python wiki.

There are two ways of getting query params:

1. Using reqeust.URL.Query()
2. Using request.Form

In second case one has to be careful as body parameters will take precedence over query parameters. A full description about getting query params can be found here

https://golangbyexample.com/net-http-package-get-query-params-golang

It depends. The System.Timers.Timer has two modes of operation.

If SynchronizingObject is set to an ISynchronizeInvoke instance then the Elapsed event will execute on the thread hosting the synchronizing object. Usually these ISynchronizeInvoke instances are none other than plain old Control and Form instances that we are all familiar with. So in that case the Elapsed event is invoked on the UI thread and it behaves similar to the System.Windows.Forms.Timer. Otherwise, it really depends on the specific ISynchronizeInvoke instance that was used.

If SynchronizingObject is null then the Elapsed event is invoked on a ThreadPool thread and it behaves similar to the System.Threading.Timer. In fact, it actually uses a System.Threading.Timer behind the scenes and does the marshaling operation after it receives the timer callback if needed.

I had this problem. I think that it was caused by the socket getting opened and no data arriving within a short time after the open. I was reading from a serial to ethernet box called a Devicemaster. I changed the Devicemaster port setting from "connect always" to "connect on data" and the problem disappeared. I have great respect for Hans Passant but I do not agree that this is an error code that you can easily solve by scrutinizing code.

The cex parameter will do that for you.

a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
        col = 1:6, space = c(0, 2))
legend("topright", 
       legend = c("a", "b", "c", "d", "e", "f"), 
       fill = 1:6, ncol = 2,
       cex = 0.75)

If you simply call interrupt(), the thread will not automatically be closed. Instead, the Thread might even continue living, if isInterrupted() is implemented accordingly. The only way to guaranteedly close a thread, as asked for by OP, is

Thread.currentThread().stop();

Method is deprecated, however.

Calling return only returns from the current method. This only terminates the thread if you're at its top level.

Nevertheless, you should work with interrupt() and build your code around it.

Add a type="search" to your input
The support is pretty decent but will not work in IE<10

<input type="search">

Older browsers

If you need IE9 support here are some workarounds

Using a standard <input type="text"> and some HTML elements:

/**
 * Clearable text inputs
 */
$(".clearable").each(function() {
  
  const $inp = $(this).find("input:text"),
      $cle = $(this).find(".clearable__clear");

  $inp.on("input", function(){
    $cle.toggle(!!this.value);
  });
  
  $cle.on("touchstart click", function(e) {
    e.preventDefault();
    $inp.val("").trigger("input");
  });
  
});

/* Clearable text inputs */
.clearable{
  position: relative;
  display: inline-block;
}
.clearable input[type=text]{
  padding-right: 24px;
  width: 100%;
  box-sizing: border-box;
}
.clearable__clear{
  display: none;
  position: absolute;
  right:0; top:0;
  padding: 0 8px;
  font-style: normal;
  font-size: 1.2em;
  user-select: none;
  cursor: pointer;
}
.clearable input::-ms-clear {  /* Remove IE default X */
  display: none;
}

<span class="clearable">
  <input type="text" name="" value="" placeholder="">
  <i class="clearable__clear">&times;</i>
</span>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

Using only a <input class="clearable" type="text"> (No additional elements)

set a class="clearable" and play with it's background image:

/**
 * Clearable text inputs
 */
function tog(v){return v ? "addClass" : "removeClass";} 
$(document).on("input", ".clearable", function(){
    $(this)[tog(this.value)]("x");
}).on("mousemove", ".x", function( e ){
    $(this)[tog(this.offsetWidth-18 < e.clientX-this.getBoundingClientRect().left)]("onX");
}).on("touchstart click", ".onX", function( ev ){
    ev.preventDefault();
    $(this).removeClass("x onX").val("").change();
});

// $('.clearable').trigger("input");
// Uncomment the line above if you pre-fill values from LS or server

/*
    Clearable text inputs
*/
.clearable{
  background: #fff url(http://i.stack.imgur.com/mJotv.gif) no-repeat right -10px center;
  border: 1px solid #999;
  padding: 3px 18px 3px 4px; /* Use the same right padding (18) in jQ! */
  border-radius: 3px;
  transition: background 0.4s;
}
.clearable.x  { background-position: right 5px center; } /* (jQ) Show icon */
.clearable.onX{ cursor: pointer; } /* (jQ) hover cursor style */
.clearable::-ms-clear {display: none; width:0; height:0;} /* Remove IE default X */

<input class="clearable" type="text" name="" value="" placeholder="" />

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

The trick is to set some right padding (I used 18px) to the input and push the background-image right, out of sight (I used right -10px center).
That 18px padding will prevent the text hide underneath the icon (while visible).
jQuery will add the class "x" (if input has value) showing the clear icon.
Now all we need is to target with jQ the inputs with class x and detect on mousemove if the mouse is inside that 18px "x" area; if inside, add the class onX.
Clicking the onX class removes all classes, resets the input value and hides the icon.

I submit my example for consideration. This is how I call some code from a controller script in the tools I make. The scripts that do the work also need to accept parameters as well, so this example shows how to pass them. It does assume the script being called is in the same directory as the controller script (script making the call).

[CmdletBinding()]
param (
[Parameter(Mandatory = $true)]
[string[]]
$Computername,

[Parameter(Mandatory = $true)]
[DateTime]
$StartTime,

[Parameter(Mandatory = $true)]
[DateTime]
$EndTime
)

$ZAEventLogDataSplat = @{
    "Computername" = $Computername
    "StartTime"    = $StartTime
    "EndTime"      = $EndTime
}

& "$PSScriptRoot\Get-ZAEventLogData.ps1" @ZAEventLogDataSplat

The above is a controller script that accepts 3 parameters. These are defined in the param block. The controller script then calls the script named Get-ZAEventLogData.ps1. For the sake of example, this script also accepts the same 3 parameters. When the controller script calls to the script that does the work, it needs to call it and pass the parameters. The above shows how I do it by splatting.
