Your family tree should use directed relations. This way you won't have a cycle.

Here's another example. I wrote a method that finds the median of the values in two sorted arrays. The method assumes the arrays are already sorted. For performance reasons, it should NOT sort the arrays first, or even check to ensure they're sorted. However, it's a serious bug to call this method with unsorted data, and we want those bugs to get caught early, in the development phase. So here's how I handled those seemingly conflicting goals:

public static int medianOf(int[] a, int[] b) {
  assert assertionOnlyIsSorted(a);      // Assertion is order n
  assert assertionOnlyIsSorted(b);
  ... // rest of implementation goes here. Algorithm is order log(n)
}

public static boolean assertionOnlyIsSorted(int[] array) {
  for (int i=1; i<array.length; ++i) {
    if (array[i] < array[i-1]) {
      return false;
    }
    return true;
  }
}

This way, the test, which is slow, is only performed during the development phase, where speed is less important than catching bugs. You want the medianOf() method to have log(n) performance, but the "is sorted" test is order n. So I put it inside an assertion, to limit its use to the development phase, and I give it a name that makes it clear it's not suitable for production.

This way I have the best of both worlds. In development, I know that any method that calls this incorrectly will get caught and fixed. And I know that the slow test to do so won't affect performance in production. (It's also a good illustration of why you want to leave assertions off in production, but turn them on in development.)

I think it's just for your convenience (and the readers of your code)

Your code, and your unit tests should be ideally self documenting which this API helps with,

Think abt what is more clear to read:

AssertTrue(!(a > 3));

or

AssertFalse(a > 3);

When you open your tests after xx months when your tests suddenly fail, it would take you much less time to understand what went wrong in the second case (my opinion). If you disagree, you can always stick with AssertTrue for all cases :)

Using junit4 and Hamcrest you get a concise method of comparing arrays. It also gives details of where the error is in the failure trace.

import static org.junit.Assert.*
import static org.hamcrest.CoreMatchers.*;

//...

assertThat(result, is(new int[] {56, 100, 2000}));

Failure Trace output:

java.lang.AssertionError: 
   Expected: is [<56>, <100>, <2000>]
   but: was [<55>, <100>, <2000>]

They look pretty much the same on Python 3.2.

As gnibbler pointed out, the first doesn't need to lookup dict, which should make it a tiny bit faster.

...   d = {'one': 1, 'two': 2}
...

...   d = dict(one='1', two='2')
...

The first answer is good for understanding how it works. But I wanted to understand how I should be using it in practice.

SUMMARY

• for moderately imbalanced data WITHOUT noise, there is not much of a difference in applying class weights
• for moderately imbalanced data WITH noise and strongly imbalanced, it is better to apply class weights
• param class_weight="balanced" works decent in the absence of you wanting to optimize manually
• with class_weight="balanced" you capture more true events (higher TRUE recall) but also you are more likely to get false alerts (lower TRUE precision)
  • as a result, the total % TRUE might be higher than actual because of all the false positives
  • AUC might misguide you here if the false alarms are an issue
• no need to change decision threshold to the imbalance %, even for strong imbalance, ok to keep 0.5 (or somewhere around that depending on what you need)

NB

The result might differ when using RF or GBM. sklearn does not have class_weight="balanced" for GBM but lightgbm has LGBMClassifier(is_unbalance=False)

I got this error when using Visual Studio 2013 with Microsoft SQL Server Management Studio 2016 trying to update database with Entity Framework migrations

The fix was to install Microsoft SQL Server Management Studio 2012 SP1 as Visual Studio 2013 was missing the necessary libraries to connect to the SQL Server database.

I put together this detailed page with all the steps I took.

The answer, u, (and many others) is in $ vimtutor.

Import and Export of a SQLite database on Android

Here is my function for export database into device storage

    } catch(IOException e) {
        e.printStackTrace();
    }
}

Here is my function for import database from device storage into android application

private void importDB(){
    String dir=Environment.getExternalStorageDirectory().getAbsolutePath();
    File sd = new File(dir);
    File data = Environment.getDataDirectory();

I am not sure it would read better but you could do the following:

while any((not condition1, not condition2, val == -1)):
    val,something1,something2 = getstuff()

    if something1==10:
        condition1 = True

    if something2==20:
        condition2 = True

This is not my prefered way to do this, cause of massive CPU consumption.

If that is actually your working code, then just keep it like that. Checking a boolean once a second causes NO measurable CPU load. None whatsoever.

The real problem is that the thread that checks the value may not see a change that has happened for an arbitrarily long time due to caching. To ensure that the value is always synchronized between threads, you need to put the volatile keyword in the variable definition, i.e.

private volatile boolean value;

Note that putting the access in a synchronized block, such as when using the notification-based solution described in other answers, will have the same effect.

For me the issue was about a comma not in the filename but as below: -

Response.ok(streamingOutput,MediaType.APPLICATION_OCTET_STREAM_TYPE).header("content-disposition", "attachment, filename=your_file_name").build();

I accidentally put a comma after attachment. Got it resolved by replacing comma with a semicolon.

You can easily create your own serializer

var car = new Car() { Name = "Ford", Owner = "John Smith" };
string json = Serialize(car);

string Serialize<T>(T o)
{
    var attr = o.GetType().GetCustomAttribute(typeof(JsonObjectAttribute)) as JsonObjectAttribute;

    var jv = JValue.FromObject(o);

    return new JObject(new JProperty(attr.Title, jv)).ToString();
}

ls=['hello','world']
ls.append('python')
['hello', 'world', 'python']

or (use insert function where you can use index position in list)

ls.insert(0,'python')
print(ls)
['python', 'hello', 'world']

You need the table name/alias in the SELECT part (maybe (vg.id, name)) :

SELECT (vg.id, name) FROM v_groups vg 
inner join people2v_groups p2vg on vg.id = p2vg.v_group_id
where p2vg.people_id =0;

import codecs

decode_hex = codecs.getdecoder("hex_codec")

# for an array
msgs = [decode_hex(msg)[0] for msg in msgs]

# for a string
string = decode_hex(string)[0]

Following code can help to write dynamic function in PHP. now the function name can be dynamically change by variable '$current_page'.

$current_page = 'home_page';
$function = @${$current_page . '_page_versions'};
$function = function() {
    echo 'current page';
};
$function();

Assuming that by "binary code" you mean just plain old data (sequences of bits, or bytes), and that by "letters" you mean characters, the answer is in two steps. But first, some background.

• A character is just a named symbol, like "LATIN CAPITAL LETTER A" or "GREEK SMALL LETTER PI" or "BLACK CHESS KNIGHT". Do not confuse a character (abstract symbol) with a glyph (a picture of a character).
• A character set is a particular set of characters, each of which is associated with a special number, called its codepoint. To see the codepoint mappings in the Unicode character set, see http://www.unicode.org/Public/UNIDATA/UnicodeData.txt.

Okay now here are the two steps:

1. The data, if it is textual, must be accompanied somehow by a character encoding, something like UTF-8, Latin-1, US-ASCII, etc. Each character encoding scheme specifies in great detail how byte sequences are interpreted as codepoints (and conversely how codepoints are encoded as byte sequences).

2. Once the byte sequences are interpreted as codepoints, you have your characters, because each character has a specific codepoint.

A couple notes:

• In some encodings, certain byte sequences correspond to no codepoints at all, so you can have character decoding errors.
• In some character sets, there are codepoints that are unused, that is, they correspond to no character at all.

In other words, not every byte sequence means something as text.

I tried all the above with v 1.8.13 to no avail. What worked for me (on macOS) was to use the doxywizard->Expert tag to fill the USE_MD_FILE_AS_MAINPAGE setting.

It made the following changes to my Doxyfile:

USE_MDFILE_AS_MAINPAGE = ../README.md
...
INPUT                  = ../README.md \
                         ../sdk/include \
                         ../sdk/src

Note the line termination for INPUT, I had just been using space as a separator as specified in the documentation. AFAICT this is the only change between the not-working and working version of the Doxyfile.

Although in most general cases the error is quite clearly that file handles have not been closed, I just encountered an instance with JDK7 on Linux that well... is sufficiently ****ed up to explain here.

The program opened a FileOutputStream (fos), a BufferedOutputStream (bos) and a DataOutputStream (dos). After writing to the dataoutputstream, the dos was closed and I thought everything went fine.

Internally however, the dos, tried to flush the bos, which returned a Disk Full error. That exception was eaten by the DataOutputStream, and as a consequence the underlying bos was not closed, hence the fos was still open.

At a later stage that file was then renamed from (something with a .tmp) to its real name. Thereby, the java file descriptor trackers lost track of the original .tmp, yet it was still open !

To solve this, I had to first flush the DataOutputStream myself, retrieve the IOException and close the FileOutputStream myself.

I hope this helps someone.

I set the NODEJS variable in the system control panel but the only thing that worked to set the path was to do it from command line as administrator.

SET PATH=%NODEJS%;%PATH%

Another trick is that once you set the path you must close the console and open a new one for the new path to be taken into account.

However for the regular user to be able to use node I had to run set path again not as admin and restart the computer

There seems to be a confusion with operator.add! When you add two lists together, the correct term for that is concat, not add. operator.concat is what you need to use.

If you're thinking functional, it is as easy as this::

>>> list2d = ((1,2,3),(4,5,6), (7,), (8,9))
>>> reduce(operator.concat, list2d)
(1, 2, 3, 4, 5, 6, 7, 8, 9)

You see reduce respects the sequence type, so when you supply a tuple, you get back a tuple. let's try with a list::

>>> list2d = [[1,2,3],[4,5,6], [7], [8,9]]
>>> reduce(operator.concat, list2d)
[1, 2, 3, 4, 5, 6, 7, 8, 9]

Aha, you get back a list.

How about performance::

>>> list2d = [[1,2,3],[4,5,6], [7], [8,9]]
>>> %timeit list(itertools.chain.from_iterable(list2d))
1000000 loops, best of 3: 1.36 µs per loop

from_iterable is pretty fast! But it's no comparison to reduce with concat.

>>> list2d = ((1,2,3),(4,5,6), (7,), (8,9))
>>> %timeit reduce(operator.concat, list2d)
1000000 loops, best of 3: 492 ns per loop

If it doesn't have to be writeable you can create such an array with np.broadcast_to:

>>> import numpy as np
>>> np.broadcast_to(True, (2, 5))
array([[ True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True]], dtype=bool)

If you need it writable you can also create an empty array and fill it yourself:

>>> arr = np.empty((2, 5), dtype=bool)
>>> arr.fill(1)
>>> arr
array([[ True,  True,  True,  True,  True],
       [ True,  True,  True,  True,  True]], dtype=bool)

These approaches are only alternative suggestions. In general you should stick with np.full, np.zeros or np.ones like the other answers suggest.

I think no one actually has answered to the first question:

Why did they create those variables?

Those variables aren't strictly necessary. It's true. You can perfectly do something like this:

MONTH_CHOICES = (
    ("JANUARY", "January"),
    ("FEBRUARY", "February"),
    ("MARCH", "March"),
    # ....
    ("DECEMBER", "December"),
)

month = models.CharField(max_length=9,
                  choices=MONTH_CHOICES,
                  default="JANUARY")

Why using variables is better? Error prevention and logic separation.

JAN = "JANUARY"
FEB = "FEBRUARY"
MAR = "MAR"
# (...)

MONTH_CHOICES = (
    (JAN, "January"),
    (FEB, "February"),
    (MAR, "March"),
    # ....
    (DEC, "December"),
)

Now, imagine you have a view where you create a new Model instance. Instead of doing this:

new_instance = MyModel(month='JANUARY')

You'll do this:

new_instance = MyModel(month=MyModel.JAN)

In the first option you are hardcoding the value. If there is a set of values you can input, you should limit those options when coding. Also, if you eventually need to change the code at the Model layer, now you don't need to make any change in the Views layer.

As an example of what del can be used for, I find it useful i situations like this:

def f(a, b, c=3):
    return '{} {} {}'.format(a, b, c)

def g(**kwargs):
    if 'c' in kwargs and kwargs['c'] is None:
        del kwargs['c']

    return f(**kwargs)

# g(a=1, b=2, c=None) === '1 2 3'
# g(a=1, b=2) === '1 2 3'
# g(a=1, b=2, c=4) === '1 2 4'

These two functions can be in different packages/modules and the programmer doesn't need to know what default value argument c in f actually have. So by using kwargs in combination with del you can say "I want the default value on c" by setting it to None (or in this case also leave it).

You could do the same thing with something like:

def g(a, b, c=None):
    kwargs = {'a': a,
              'b': b}
    if c is not None:
        kwargs['c'] = c

    return f(**kwargs)

However I find the previous example more DRY and elegant.

If you're using http/https and you're looking to FULLY AUTOMATE the process without requiring any user input or any user prompt at all (for example: inside a CI/CD pipeline), you may use the following approach leveraging git credential.helper

GIT_CREDS_PATH="/my/random/path/to/a/git/creds/file"
# Or you may choose to not specify GIT_CREDS_PATH at all.
# See https://git-scm.com/docs/git-credential-store#FILES for the defaults used

git config --global credential.helper "store --file ${GIT_CREDS_PATH}"
echo "https://alice:${ALICE_GITHUB_PASSWORD}@github.com" > ${GIT_CREDS_PATH}

where you may choose to set the ALICE_GITHUB_PASSWORD environment variable from a previous shell command or from your pipeline config etc.

Remember that "store" based git-credential-helper stores passwords & values in plain-text. So make sure your token/password has very limited permissions.

Now simply use https://[email protected]/my_repo.git wherever your automated system needs to fetch the repo - it will use the credentials for alice in github.com as store by git-credential-helper.

Yes, it's a standard practice to commit package-lock.json.

The main reason for committing package-lock.json is that everyone in the project is on the same package version.

Pros:

• If you follow strict versioning and don't allow updating to major versions automatically to save yourself from backward-incompatible changes in third-party packages committing package-lock helps a lot.
• If you update a particular package, it gets updated in package-lock.json and everyone using the repository gets updated to that particular version when they take the pull of your changes.

Cons:

• It can make your pull requests look ugly :)

npm install won't make sure that everyone in the project is on the same package version. npm ci will help with this.

Use this code it will work OK. You shall click on TextBox1 and then go to event and select Keyup and double click on it. You wil then get the lines for the SUB.

Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As      
System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
    If e.KeyCode = Keys.Enter Then
        MsgBox("Fel lösenord")

    End If
End Sub

Try this regex:

[5-9]\d+|\d{3,}

1 . Add this line on top in component.

declare var require: any

2 . add this line in your component class.

imgname= require("../images/imgname.png");

3. add this 'imgname' in img src tag on html page.

   <img src={{imgname}} alt="">

I'd do (added caching):

var bbx = $("#blackbox");
 bbx.css('background-color') === 'rgb(255, 192, 203)' ? bbx.css('background','black') : bbx.css('background','pink')

I had to change the first operator as css() returns the rgb value of the color

Happy file huntin' SO community :)

Here's how it looks like when ran via phpmyadmin:

I think will work.

$('#DivID').height('675px');

This worked for me as-
HTML-

    <div style="background-color: #535; width: 100%; height: 80px;">
        <div class="center">
            Test <br>
            kumar adnioas<br>
            sanjay<br>
            1990
        </div>
    </div> 

CSS-

.center {
    position: relative;
    left: 50%;
    top: 50%;
    height: 82%;
    transform: translate(-50%, -50%);
    transform: -webkit-translate(-50%, -50%);
    transform: -ms-translate(-50%, -50%);
   }  

Hope will help you too.

first of all you will go to your project what you are created and next right click in your mouse and select properties in the bottom and select build in path in the left corner and add external jar file add click apply .that's it

Try to use the new '@supports' feature, here is one good hack that you might like:

* UPDATE!!! * Microsoft Edge and Safari 9 both added support for the @supports feature in Fall 2015, Firefox also -- so here is my updated version for you:

/* Chrome 29+ (Only) */

@supports (-webkit-appearance:none) and (not (overflow:-webkit-marquee))
and (not (-ms-ime-align:auto)) and (not (-moz-appearance:none)) { 
   .selector { color:red; } 
}

More info on this here (the reverse... Safari but not Chrome): [ is there a css hack for safari only NOT chrome? ]

The previous CSS Hack [before Edge and Safari 9 or newer Firefox versions]:

/* Chrome 28+ (now also Microsoft Edge, Firefox, and Safari 9+) */

@supports (-webkit-appearance:none) { .selector { color:red; } }

This worked for (only) chrome, version 28 and newer.

(The above chrome 28+ hack was not one of my creations. I found this on the web and since it was so good I sent it to BrowserHacks.com recently, there are others coming.)

August 17th, 2014 update: As I mentioned, I have been working on reaching more versions of chrome (and many other browsers), and here is one I crafted that handles chrome 35 and newer.

/* Chrome 35+ */

_::content, _:future, .selector:not(*:root) { color:red; }

In the comments below it was mentioned by @BoltClock about future, past, not... etc... We can in fact use them to go a little farther back in Chrome history.

So then this is one that also works but not 'Chrome-only' which is why I did not put it here. You still have to separate it by a Safari-only hack to complete the process. I have created css hacks to do this however, not to worry. Here are a few of them, starting with the simplest:

/* Chrome 26+, Safari 6.1+ */

_:past, .selector:not(*:root) { color:red; }

Or instead, this one which goes back to Chrome 22 and newer, but Safari as well...

/* Chrome 22+, Safari 6.1+ */

@media screen and (-webkit-min-device-pixel-ratio:0)
and (min-resolution:.001dpcm),
screen and(-webkit-min-device-pixel-ratio:0)
{
    .selector { color:red; } 
}

The block of Chrome versions 22-28 (more complicated but works nicely) are also possible to target via a combination I worked out:

/* Chrome 22-28 (Only!) */

@media screen and(-webkit-min-device-pixel-ratio:0)
{
    .selector  {-chrome-:only(;

       color:red; 

    );}
}

Now follow up with this next couple I also created that targets Safari 6.1+ (only) in order to still separate Chrome and Safari. Updated to include Safari 8

/* Safari 6.1-7.0 */

@media screen and (-webkit-min-device-pixel-ratio:0) and (min-color-index:0)
{
    .selector {(;  color:blue;  );} 
}


/* Safari 7.1+ */

_::-webkit-full-page-media, _:future, :root .selector { color:blue; } 

So if you put one of the Chrome+Safari hacks above, and then the Safari 6.1-7 and 8 hacks in your styles sequentially, you will have Chrome items in red, and Safari items in blue.

If you use Microsoft Azure Storage Explorer, there is a "New Folder" button that allows you to create a folder in a container. This is actually a virtual folder:

I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.

If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE

echo %WORKSPACE%

If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &, &&, or || are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.

setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
  set WORKSPACE=AFTER
  echo Normal Expansion = %WORKSPACE%
  echo Delayed Expansion = !WORKSPACE!
)

The output of the above is

Normal Expansion = BEFORE
Delayed Expansion = AFTER

Use HELP SET or SET /? from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.

Answered code-snippet posted by Leandros seems bit old. I have fixed and made it compilable in Swift 5.

  CASE WHEN ISNUMERIC(QTY + 'e0') = 1 THEN CAST(QTY AS float) ELSE null END AS MyFloat
  CASE WHEN ISNUMERIC(QTY + 'e0') = 0 THEN QTY ELSE null END AS MyVarchar

• Two data types requires two columns
• Adding e0 fixes some ISNUMERIC issues (such as + - . and empty string being accepted)

Enter the submodule directory:

cd projB/projA

Pull the repo from you project A (will not update the git status of your parent, project B):

git pull origin master

Go back to the root directory & check update:

cd ..
git status

If the submodule updated before, it will show something like below:

# Not currently on any branch.
# Changed but not updated:
#   (use "git add ..." to update what will be committed)
#   (use "git checkout -- ..." to discard changes in working directory)
#
#       modified:   projB/projA (new commits)
#

Then, commit the update:

git add projB/projA
git commit -m "projA submodule updated"

UPDATE

As @paul pointed out, since git 1.8, we can use

git submodule update --remote --merge

to update the submodule to the latest remote commit. It'll be convenient in most cases.

That example is pretty vague, but maybe something like this?

items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [''.join(items[3:6])]

It basically does a splice (or assignment to a slice) operation. It removes items 3 to 6 and inserts a new list in their place (in this case a list with one item, which is the concatenation of the three items that were removed.)

For any type of list, you could do this (using the + operator on all items no matter what their type is):

items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [reduce(lambda x, y: x + y, items[3:6])]

This makes use of the reduce function with a lambda function that basically adds the items together using the + operator.

For Windows installation, a Windows user is created. And "psql" use this user for connection to the port. If you change the PostgreSQL user's password, it won't change the Windows one. The commandline juste below works only if you have access to commandline.

Instead you could use Windows GUI application "c:\Windows\system32\lusrmgr.exe". This app manage users created by Windows. So you can now modify the password.

Addition to most voted answer.

obtainStyledAttributes()

I want to add some words about obtainStyledAttributes() usage, when we create custom view using android:xxx prdefined attributes. Especially when we use TextAppearance.
As was mentioned in "2. Creating constructors", custom view gets AttributeSet on its creation. Main usage we can see in TextView source code (API 16).

final Resources.Theme theme = context.getTheme();

// TextAppearance is inspected first, but let observe it later

TypedArray a = theme.obtainStyledAttributes(
            attrs, com.android.internal.R.styleable.TextView, defStyle, 0);

int n = a.getIndexCount();
for (int i = 0; i < n; i++) 
{
    int attr = a.getIndex(i);
    // huge switch with pattern value=a.getXXX(attr) <=> a.getXXX(a.getIndex(i))
}
a.recycle();

What we can see here?
obtainStyledAttributes(AttributeSet set, int[] attrs, int defStyleAttr, int defStyleRes)
Attribute set is processed by theme according to documentation. Attribute values are compiled step by step. First attributes are filled from theme, then values are replaced by values from style, and finally exact values from XML for special view instance replace others.
Array of requested attributes - com.android.internal.R.styleable.TextView
It is an ordinary array of constants. If we are requesting standard attributes, we can build this array manually.

What is not mentioned in documentation - order of result TypedArray elements.
When custom view is declared in attrs.xml, special constants for attribute indexes are generated. And we can extract values this way: a.getString(R.styleable.MyCustomView_android_text). But for manual int[] there are no constants. I suppose, that getXXXValue(arrayIndex) will work fine.

And other question is: "How we can replace internal constants, and request standard attributes?" We can use android.R.attr.* values.

So if we want to use standard TextAppearance attribute in custom view and read its values in constructor, we can modify code from TextView this way:

ColorStateList textColorApp = null;
int textSize = 15;
int typefaceIndex = -1;
int styleIndex = -1;

Resources.Theme theme = context.getTheme();

TypedArray a = theme.obtainStyledAttributes(attrs, R.styleable.CustomLabel, defStyle, 0);
TypedArray appearance = null;
int apResourceId = a.getResourceId(R.styleable.CustomLabel_android_textAppearance, -1);
a.recycle();
if (apResourceId != -1)
{
    appearance = 
        theme.obtainStyledAttributes(apResourceId, new int[] { android.R.attr.textColor, android.R.attr.textSize, 
            android.R.attr.typeface, android.R.attr.textStyle });
}
if (appearance != null)
{
    textColorApp = appearance.getColorStateList(0);
    textSize = appearance.getDimensionPixelSize(1, textSize);
    typefaceIndex = appearance.getInt(2, -1);
    styleIndex = appearance.getInt(3, -1);

    appearance.recycle();
}

Where CustomLabel is defined:

<declare-styleable name="CustomLabel">
    <!-- Label text. -->
    <attr name="android:text" />
    <!-- Label text color. -->
    <attr name="android:textColor" />
    <!-- Combined text appearance properties. -->
    <attr name="android:textAppearance" />
</declare-styleable>

Maybe, I'm mistaken some way, but Android documentation on obtainStyledAttributes() is very poor.

Extending standard UI component

At the same time we can just extend standard UI component, using all its declared attributes. This approach is not so good, because TextView for instance declares a lot of properties. And it will be impossible to implement full functionality in overriden onMeasure() and onDraw().

But we can sacrifice theoretical wide reusage of custom component. Say "I know exactly what features I will use", and don't share code with anybody.

Then we can implement constructor CustomComponent(Context, AttributeSet, defStyle). After calling super(...) we will have all attributes parsed and available through getter methods.

Your css will only work in IE browser. And the css suggessted by hayk.mart will olny work in webkit browsers. And by using different css hacks you can't style your browsers scroll bars with a same result.

So, it is better to use a jQuery/Javascript plugin to achieve a cross browser solution with a same result.

Solution:

By Using jScrollPane a jQuery plugin, you can achieve a cross browser solution

See This Demo

No one has ever suggested a RegExp solution. So here is one:

Function TrimTrailingLineBreak(pText)
    Dim oRE: Set oRE = New RegExp: oRE.Global = True
    oRE.Pattern = "(.*?)(\n|(\r\n)){1}$"
    TrimTrailingLineBreak = oRE.Replace(pText, "$1")
End Function

It captures and returns everything up until a single ({1}) trailing new line (\n), or carriage return & new line (\r\n), at the end of the text ($).
To remove all trailing line breaks change {1} to *.
And to remove all trailing whitespace (including line breaks) use oRE.Pattern = "(.*?)\s*$".

If you want to disable ActionMode for copy/pasting, you need to override 2 callbacks. This works for both TextView and EditText (or TextInputEditText)

import android.view.ActionMode

fun TextView.disableCopyPaste() {
  isLongClickable = false
  setTextIsSelectable(false)
  customSelectionActionModeCallback = object : ActionMode.Callback {
    override fun onCreateActionMode(mode: ActionMode?, menu: Menu) = false
    override fun onPrepareActionMode(mode: ActionMode?, menu: Menu) = false
    override fun onActionItemClicked(mode: ActionMode?, item: MenuItem) = false
    override fun onDestroyActionMode(mode: ActionMode?) {}
  }
  //disable action mode when edittext gain focus at first
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    customInsertionActionModeCallback = object : ActionMode.Callback {
      override fun onCreateActionMode(mode: ActionMode?, menu: Menu) = false
      override fun onPrepareActionMode(mode: ActionMode?, menu: Menu) = false
      override fun onActionItemClicked(mode: ActionMode?, item: MenuItem) = false
      override fun onDestroyActionMode(mode: ActionMode?) {}
    }
  }
}

This extension is based off above @Alexandr solution and worked fine for me.

if val % 1 == 0:
    val = int(val)

else:
    val = float(val)

This worked for me.

How it works: if the remainder of the quotient of val and 1 is 0, val has to be an integer and can, therefore, be declared to be int without having to worry about losing decimal numbers.

Compare these two situations:

A:

val = 12.00

if val % 1 == 0:
    val = int(val)
else:
    val = float(val)

print(val)

In this scenario, the output is 12, because 12.00 divided by 1 has the remainder of 0. With this information we know, that val doesn't have any decimals and we can declare val to be int.

B:

val = 13.58

if val % 1 == 0:
    val = int(val)
else:
    val = float(val)

print(val)

This time the output is 13.58, because when val is divided by 1 there is a remainder (0.58) and therefore val is declared to be a float.

By just declaring the number to be an int (without testing the remainder) decimal numbers will be cut off.

This way there are no zeros in the end and no other than the zeros will be ignored.

Try the following:

color.gradient <- function(x, colors=c("red","yellow","green"), colsteps=100) {
  return( colorRampPalette(colors) (colsteps) [ findInterval(x, seq(min(x),max(x), length.out=colsteps)) ] )
}
x <- c((1:100)^2, (100:1)^2)
plot(x,col=color.gradient(x), pch=19,cex=2)

I used Union to string together queries. Don't know if it's the most efficient way, but it works.

SELECT * FROM table1 WHERE name LIKE '%Bob%' Union
SELCET * FROM table2 WHERE name LIKE '%Bob%';

        public void dateDifferenceExample() {

        // Set the date for both of the calendar instance
        GregorianCalendar calDate = new GregorianCalendar(2012, 10, 02,5,23,43);
        GregorianCalendar cal2 = new GregorianCalendar(2015, 04, 02);

        // Get the represented date in milliseconds
        long millis1 = calDate.getTimeInMillis();
        long millis2 = cal2.getTimeInMillis();

        // Calculate difference in milliseconds
        long diff = millis2 - millis1;

        // Calculate difference in seconds
        long diffSeconds = diff / 1000;

        // Calculate difference in minutes
        long diffMinutes = diff / (60 * 1000);

        // Calculate difference in hours
        long diffHours = diff / (60 * 60 * 1000);

        // Calculate difference in days
        long diffDays = diff / (24 * 60 * 60 * 1000);
    Toast.makeText(getContext(), ""+diffSeconds, Toast.LENGTH_SHORT).show();


}

The problem arose because you added the following code as request header in your front-end :

headers.append('Access-Control-Allow-Origin', 'http://localhost:3000');
headers.append('Access-Control-Allow-Credentials', 'true');

Those headers belong to response, not request. So remove them, including the line :

headers.append('GET', 'POST', 'OPTIONS');

Your request had 'Content-Type: application/json', hence triggered what is called CORS preflight. This caused the browser sent the request with OPTIONS method. See CORS preflight for detailed information.

Therefore in your back-end, you have to handle this preflighted request by returning the response headers which include :

Access-Control-Allow-Origin : http://localhost:3000
Access-Control-Allow-Credentials : true
Access-Control-Allow-Methods : GET, POST, OPTIONS
Access-Control-Allow-Headers : Origin, Content-Type, Accept

Of course, the actual syntax depends on the programming language you use for your back-end.

In your front-end, it should be like so :

function performSignIn() {
    let headers = new Headers();

    headers.append('Content-Type', 'application/json');
    headers.append('Accept', 'application/json');
    headers.append('Authorization', 'Basic ' + base64.encode(username + ":" +  password));
    headers.append('Origin','http://localhost:3000');

    fetch(sign_in, {
        mode: 'cors',
        credentials: 'include',
        method: 'POST',
        headers: headers
    })
    .then(response => response.json())
    .then(json => console.log(json))
    .catch(error => console.log('Authorization failed : ' + error.message));
}

Place your pointer on the dock button and long click it (some seconds) or right & left mouse click depending on the browser version.

Type _type = myclass.GetType();
PropertyInfo[] _propertyInfos = _type.GetProperties();
Boolean _test = _propertyInfos[0].PropertyType.GetGenericTypeDefinition()

Use #element{ height:100vh}

This will set the height of the #element to 100% of viewport. Hope this helps.

    SELECT

       '0' AS d
    FROM other_table

You have to just replace your <ScrollView ></ScrollView> with this Custom ScrollView like <com.tmd.utils.VerticalScrollview > </com.tmd.utils.VerticalScrollview >

package com.tmd.utils;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.ScrollView;

public class VerticalScrollview extends ScrollView{

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

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

        public VerticalScrollview(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);
        }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        final int action = ev.getAction();
        switch (action)
        {
            case MotionEvent.ACTION_DOWN:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: DOWN super false" );
                    super.onTouchEvent(ev);
                    break;

            case MotionEvent.ACTION_MOVE:
                    return false; // redirect MotionEvents to ourself

            case MotionEvent.ACTION_CANCEL:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: CANCEL super false" );
                    super.onTouchEvent(ev);
                    break;

            case MotionEvent.ACTION_UP:
                    Log.i("VerticalScrollview", "onInterceptTouchEvent: UP super false" );
                    return false;

            default: Log.i("VerticalScrollview", "onInterceptTouchEvent: " + action ); break;
        }

        return false;
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        super.onTouchEvent(ev);
        Log.i("VerticalScrollview", "onTouchEvent. action: " + ev.getAction() );
         return true;
    }
}

Working Cross-browser Solution

This problem has been plaguing us all for years.

To help in all cases, I have laid out the CSS only approach, and a jQuery approach in case the css caveats are a problem.

Here's a CSS only solution I came up with that works in all circumstances, with a few minor caveats.

The basics are simple, it hides the overflow of the span, and sets the max height based on the line height as suggested by Eugene Xa.

Then there is a pseudo class after the containing div that places the ellipsis nicely.

Caveats

This solution will always place the ellipsis, regardless if there is need for it.

If the last line ends with an ending sentence, you will end up with four dots....

You will need to be happy with justified text alignment.

The ellipsis will be to the right of the text, which can look sloppy.

jQuery Approach

In my opinion this is the best solution, but not everyone can use JS. Basically, the jQuery will check any .text element, and if there are more chars than the preset max var, it will cut the rest off and add an ellipsis.

There are no caveats to this approach, however this code example is meant only to demonstrate the basic idea - I wouldn't use this in production without improving on it for a two reasons:

1) It will rewrite the inner html of .text elems. whether needed or not. 2) It does no test to check that the inner html has no nested elems - so you are relying a lot on the author to use the .text correctly.

Edited

Thanks for the catch @markzzz

This is a jQuery approach to limiting a body of text to n words, and end with an ellipsis -->

In Python 3, dict.values() (along with dict.keys() and dict.items()) returns a view, rather than a list. See the documentation here. You therefore need to wrap your call to dict.values() in a call to list like so:

v = list(d.values())
{names[i]:v[i] for i in range(len(names))}

You can make the single letter optional by adding a ? after it as:

([A-Z]{1}?)

The quantifier {1} is redundant so you can drop it.

var a = [];
a.length > 0

I would just check the length. You could potentially wrap it in a helper method if you like.

I suggest you to update your SDK and start new project and recompile everything you have. It seems you have some inner program errors. Or you are missing package.

And ofc do what Abdijeek said.

There are several ways to do this:

InStr

You can use the InStr build-in function to test if a String contains a substring. InStr will either return the index of the first match, or 0. So you can test if a String begins with a substring by doing the following:

If InStr(1, "Hello World", "Hello W") = 1 Then
    MsgBox "Yep, this string begins with Hello W!"
End If

If InStr returns 1, then the String ("Hello World"), begins with the substring ("Hello W").

Like

You can also use the like comparison operator along with some basic pattern matching:

If "Hello World" Like "Hello W*" Then
    MsgBox "Yep, this string begins with Hello W!"
End If

In this, we use an asterisk (*) to test if the String begins with our substring.

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

Invoking an empty time.Time struct literal will return Go's zero date. Thus, for the following print statement:

fmt.Println(time.Time{})

The output is:

0001-01-01 00:00:00 +0000 UTC

For the sake of completeness, the official documentation explicitly states:

The zero value of type Time is January 1, year 1, 00:00:00.000000000 UTC.

Hi its quite simple to make switch between buttons using switch case:-

 package com.example.browsebutton;


    import android.app.Activity;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.Toast;

        public class MainActivity extends Activity implements OnClickListener {
        Button b1,b2;
            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);
                b1=(Button)findViewById(R.id.button1);

                b2=(Button)findViewById(R.id.button2);
                b1.setOnClickListener(this);
                b2.setOnClickListener(this);
            }



            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                 int id=v.getId();
                 switch(id) {
                    case R.id.button1:
                  Toast.makeText(getBaseContext(), "btn1", Toast.LENGTH_LONG).show();
                //Your Operation

                  break;

                    case R.id.button2:
                          Toast.makeText(getBaseContext(), "btn2", Toast.LENGTH_LONG).show();


                          //Your Operation
                          break;
            }

        }}

You can also control optimisations internally with #pragma GCC push_options

#pragma GCC push_options
/* #pragma GCC optimize ("unroll-loops") */

I found a straight forward way of solving this, with the use of JSON.parse.

Let's assume the json below is inside the variable jsontext.

[
  ["Blankaholm", "Gamleby"],
  ["2012-10-23", "2012-10-22"],
  ["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
  ["57.586174","16.521841"], ["57.893162","16.406090"]
]

The solution is this:

var parsedData = JSON.parse(jsontext);

Now I can access the elements the following way:

var cities = parsedData[0];

On a mac, run the following command to find id of the process which is using port 8081
sudo lsof -i :8081
Then run the following to terminate process:
kill -9 23583

Here is how it will look like

explode() might be the function you are looking for

$array = explode(' ',$str);

You can do it in pure CSS using the :after pseudo-element and getting creative with the margins.

Here's an example, using Font Awesome for the search icon:

.search-box-container input {_x000D_
  padding: 5px 20px 5px 5px;_x000D_
}_x000D_
_x000D_
.search-box-container:after {_x000D_
    content: "\f002";_x000D_
    font-family: FontAwesome;_x000D_
    margin-left: -25px;_x000D_
    margin-right: 25px;_x000D_
}

<!-- font awesome -->_x000D_
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
_x000D_
_x000D_
<div class="search-box-container">_x000D_
  <input type="text" placeholder="Search..."  />_x000D_
</div>

Remove the comma

receipt int(10),

And also AUTO INCREMENT should be a KEY

double datatype also requires the precision of decimal places so right syntax is double(10,2)

If you want a copy-paste bash script:

var=$(mysql -e 'SELECT CONCAT("ALTER TABLE ", TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_czech_ci;") AS execTabs FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA="zabbix" AND TABLE_TYPE="BASE TABLE"' -uroot -p )

var+='ALTER DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_general_ci;'

echo $var | cut -d " " -f2- | mysql -uroot -p zabbix

Change zabbix to your database name.

Not sure if it helps you still... but I had to do a small trick to make the image bigger but keeping it responsive

@media screen and (max-width: 368px) {
    img.smallResolution{
        min-height: 150px;
    }

}

Hope it helps P.S. The max width can be anything you like

We can break both a $(selector).each() loop and a $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

return false; // this is equivalent of 'break' for jQuery loop

return;       // this is equivalent of 'continue' for jQuery loop

Note that $(selector).each() and $.each() are different functions.

References:

• $(selector).each()
• $.each()
• What is the difference between $.each(selector) and $(selector).each()

if you user $criteria, I recommend blow usage:

$criteria = new CDbCriteria();
$criteria->compare('email_id', 101);
$comments = EmailArchive::model()->findAll($criteria);

string.find("substring") will help you. This function returns -1 when there is no substring.

This is the only solution possible for using nothing but cut:

echo "s.t.r.i.n.g." | cut -d'.' -f2- [repeat_following_part_forever_or_until_out_of_memory:] | cut -d'.' -f2-

Using this solution, the number of fields can indeed be unknown and vary from time to time. However as line length must not exceed LINE_MAX characters or fields, including the new-line character, then an arbitrary number of fields can never be part as a real condition of this solution.

Yes, a very silly solution but the only one that meets the criterias I think.

this example will be creating logger for each minute, if you want to change for each day change the DatePattern value.

   <param name="File" value="./applogs/logger.log" />

   <appendToFile value="true" />
   <param name="DatePattern" value="'.'yyyy_MM_dd_HH_mm"/>
   <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
      <param name="fileNamePattern" value="./applogs/logger_%d{ddMMMyyyy HH:mm:ss}.log"/>
      <param name="rollOver" value="TRUE"/>
   </rollingPolicy>
   <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d{ddMMMyyyy HH:mm:ss,SSS}^[%X{l4j_mdc_key}]^[%c{1}]^ %-5p %m%n" />
   </layout>

try {
    OkHttpClient client = new OkHttpClient();
    Request request = new Request.Builder()
        .url(urls[0])
        .build();
    Response responses = null;

    try {
        responses = client.newCall(request).execute();
    } catch (IOException e) {
        e.printStackTrace();
    }
    String jsonData = responses.body().string();
    JSONObject Jobject = new JSONObject(jsonData);
    JSONArray Jarray = Jobject.getJSONArray("employees");

    for (int i = 0; i < Jarray.length(); i++) {
        JSONObject object     = Jarray.getJSONObject(i);
    }
}

Example add to your columns:

JCol employees  = new employees();
colums.Setid(object.getInt("firstName"));
columnlist.add(lastName);           

Another solution for class based vanilla JS using a distance threshold

private initDetectDrag(element) {
    let clickOrigin = { x: 0, y: 0 };
    const dragDistanceThreshhold = 20;

    element.addEventListener('mousedown', (event) => {
        this.isDragged = false
        clickOrigin = { x: event.clientX, y: event.clientY };
    });
    element.addEventListener('mousemove', (event) => {
        if (Math.sqrt(Math.pow(clickOrigin.y - event.clientY, 2) + Math.pow(clickOrigin.x - event.clientX, 2)) > dragDistanceThreshhold) {
            this.isDragged = true
        }
    });
}

Add inside the class (SOMESLIDER_ELEMENT can also be document to be global):

private isDragged: boolean;
constructor() {
    this.initDetectDrag(SOMESLIDER_ELEMENT);
    this.doSomeSlideStuff(SOMESLIDER_ELEMENT);
    element.addEventListener('click', (event) => {
        if (!this.sliderIsDragged) {
            console.log('was clicked');
        } else {
            console.log('was dragged, ignore click or handle this');
        }
    }, false);
}

When adding new element with jquery plugin calls, you can do like the following:

$('<div>...</div>').hoverCard(function(){...}).appendTo(...)

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

The Best and easy Way is to create this method And Pass Array And Value:

- (NSArray *) filter:(NSArray *)array where:(NSString *)key is:(id)value{
    NSMutableArray *temArr=[[NSMutableArray alloc] init];
    for(NSDictionary *dic in self)
        if([dic[key] isEqual:value])
            [temArr addObject:dic];
    return temArr;
}

If you use complex objects, you should apply enableComplexMapKeySerialization(), as stated in https://stackoverflow.com/a/24635655/2914140 and https://stackoverflow.com/a/26374888/2914140.

Gson gson = new GsonBuilder().enableComplexMapKeySerialization().create();
Map<Point, String> original = new LinkedHashMap<Point, String>();
original.put(new Point(5, 6), "a");
original.put(new Point(8, 8), "b");
System.out.println(gson.toJson(original));

Output will be:

{
 "(5,6)": "a",
 "(8,8)": "b"
}

This is one of the ways:

String toDate = "05/11/2010";

if (new SimpleDateFormat("MM/dd/yyyy").parse(toDate).getTime() / (1000 * 60 * 60 * 24) >= System.currentTimeMillis() / (1000 * 60 * 60 * 24)) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

A bit more easy interpretable:

String toDateAsString = "05/11/2010";
Date toDate = new SimpleDateFormat("MM/dd/yyyy").parse(toDateAsString);
long toDateAsTimestamp = toDate.getTime();
long currentTimestamp = System.currentTimeMillis();
long getRidOfTime = 1000 * 60 * 60 * 24;
long toDateAsTimestampWithoutTime = toDateAsTimestamp / getRidOfTime;
long currentTimestampWithoutTime = currentTimestamp / getRidOfTime;

if (toDateAsTimestampWithoutTime >= currentTimestampWithoutTime) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Oh, as a bonus, the JodaTime's variant:

String toDateAsString = "05/11/2010";
DateTime toDate = DateTimeFormat.forPattern("MM/dd/yyyy").parseDateTime(toDateAsString);
DateTime now = new DateTime();

if (!toDate.toLocalDate().isBefore(now.toLocalDate())) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

you may try the following code:

mainWindow = new BrowserWindow({
        webPreferences: {
            nodeIntegration:false,
        }
});

  <div class="inter">
      <p>Liste des Produits</p>
      <ul>
          <li><a href="#1">P1</a></li>
          <li><a href="#2">P2</a></li>
          <li><a href="#3">P3</a></li>
      </ul>
  </div>

        $(document).ready(function(){
            $(".inter li").bind(
            "click", function(){
                alert($(this).children("a").text());
            });
        });

Try like this.

<div style="overflow-y: scroll; height:400px;">

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

Mock data:

df = pd.DataFrame({'Group':['A','A','A','B','C','B','B','C','A','C'],\
                  'Apple':np.random.rand(10),'Orange':np.random.rand(10)})
df = df[['Group','Apple','Orange']]

        Group    Apple     Orange
    0      A  0.465636  0.537723
    1      A  0.560537  0.727238
    2      A  0.268154  0.648927
    3      B  0.722644  0.115550
    4      C  0.586346  0.042896
    5      B  0.562881  0.369686
    6      B  0.395236  0.672477
    7      C  0.577949  0.358801
    8      A  0.764069  0.642724
    9      C  0.731076  0.302369

You can use the Seaborn library for these plots. First melt the dataframe to format data and then create the boxplot of your choice.

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
dd=pd.melt(df,id_vars=['Group'],value_vars=['Apple','Orange'],var_name='fruits')
sns.boxplot(x='Group',y='value',data=dd,hue='fruits')

If you're using WPF there is a LoadCompleted event.

If it's Windows.Forms, the DocumentCompleted event should be the correct one. If the page you're loading has frames, your WebBrowser control will fire the DocumentCompleted event for each frame (see here for more details). I would suggest checking the IsBusy property each time the event is fired and if it is false then your page is fully done loading.

break interacts solely with the closest enclosing loop or switch, whether it be a for, while or do .. while type. It is frequently referred to as a goto in disguise, as all loops in C can in fact be transformed into a set of conditional gotos:

for (A; B; C) D;
// translates to
A;
goto test;
loop: D;
iter: C;
test: if (B) goto loop;
end:

while (B) D;          // Simply doesn't have A or C
do { D; } while (B);  // Omits initial goto test
continue;             // goto iter;
break;                // goto end;

The difference is, continue and break interact with virtual labels automatically placed by the compiler. This is similar to what return does as you know it will always jump ahead in the program flow. Switches are slightly more complicated, generating arrays of labels and computed gotos, but the way break works with them is similar.

The programming error the notice refers to is misunderstanding break as interacting with an enclosing block rather than an enclosing loop. Consider:

for (A; B; C) {
   D;
   if (E) {
       F;
       if (G) break;   // Incorrectly assumed to break if(E), breaks for()
       H;
   }
   I;
}
J;

Someone thought, given such a piece of code, that G would cause a jump to I, but it jumps to J. The intended function would use if (!G) H; instead.

In Laravel 5, there is a .env file,

It looks like

APP_ENV=local
APP_DEBUG=true
APP_KEY=YOUR_API_KEY

DB_HOST=YOUR_HOST
DB_DATABASE=YOUR_DATABASE
DB_USERNAME=YOUR_USERNAME
DB_PASSWORD=YOUR_PASSWORD

CACHE_DRIVER=file

QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525

Edit that .env There is .env.sample is there , try to create from that if no such .env file found.

You can communicate with docker from inside of a container using unix socket via Docker Remote API:

https://docs.docker.com/engine/reference/api/docker_remote_api/

In a container, you can find out a shortedned docker id by examining $HOSTNAME env var. According to doc, there is a small chance of collision, I think that for small number of container, you do not have to worry about it. I don't know how to get full id directly.

You can inspect container similar way as outlined in banyan answer:

GET /containers/4abbef615af7/json HTTP/1.1

Response:

HTTP/1.1 200 OK
Content-Type: application/json

{
         "Id": "4abbef615af7......  ",
         "Created": "2013.....",
         ...
}

Alternatively, you can transfer docker id to the container in a file. The file is located on "mounted volume" so it is transfered to container:

docker run -t -i -cidfile /mydir/host1.txt -v /mydir:/mydir ubuntu /bin/bash

The docker id (shortened) will be in file /mydir/host1.txt in the container.

It is caused because global and local angular versions are different. To update global angular version, first you need to run the following command in command prompt or vs code terminal

npm install --save-dev @angular/cli@latest

After that if there are any vulnerability found then run the following command to fix them

npm audit fix

If you have several dialogs that could be opened on a page, this will allow any of them to be closed by clicking on the background:

$('body').on('click','.ui-widget-overlay', function() {
    $('.ui-dialog').filter(function () {
    return $(this).css("display") === "block";
    }).find('.ui-dialog-content').dialog('close');
});

(Only works for modal dialogs, as it relies on '.ui-widget-overlay'. And it does close all open dialogs any time the background of one of them is clicked.)

I recently had this issue. The problem was that the method I was trying to mock had no access modifier. Adding public solved the problem.

I see that you used pip to update. This is strongly discouraged (at least in Spyder 3). The Spyder update notices I receive have always included the following:

"IMPORTANT NOTE: It seems that you are using Spyder with Anaconda/Minconda. Please don't use pip to update it as that will probably break your installation. Instead please wait until new conda packages are available and use conda to perform the update."

This is an additional way to find out the number of CPU cores (and a lot of other information), but this code requires an additional dependence:

Native Operating System and Hardware Information https://github.com/oshi/oshi

SystemInfo systemInfo = new SystemInfo();
HardwareAbstractionLayer hardwareAbstractionLayer = systemInfo.getHardware();
CentralProcessor centralProcessor = hardwareAbstractionLayer.getProcessor();

Get the number of logical CPUs available for processing:

centralProcessor.getLogicalProcessorCount();

Swift version

This is the Swift version of David's Objective-C answer. You use the global queue to run things in the background and the main queue to update the UI.

DispatchQueue.global(qos: .background).async {
    
    // Background Thread
    
    DispatchQueue.main.async {
        // Run UI Updates
    }
}

The full command is:

dir /b /a-d

Let me break it up;

Basically the /b is what you look for.

/a-d will exclude the directory names.

For more information see dir /? for other arguments that you can use with the dir command.

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

You can use PhoneNumberUtils if your phone format is one of the described formats. If none of the utility function match your needs, use regular experssions.

Actually it's a bug and nobody found a workaround so far. An issue has been created. The bug is still here in honeycomb.

You could also use the below code to redirect to the main page (home):

{ path: '', redirectTo: 'home', pathMatch: 'full'}

After specifying your redirect as above, you can redirect the other pages, for example:

{ path: 'add-new-registration', component: AddNewRegistrationComponent},
{ path: 'view-registration', component: ViewRegistrationComponent},
{ path: 'home', component: HomeComponent}

Nice and simple, from Pinal Dave's site:

http://blog.sqlauthority.com/2007/04/29/sql-server-random-number-generator-script-sql-query/

DECLARE @Random INT;
DECLARE @Upper INT;
DECLARE @Lower INT
SET @Lower = 3 ---- The lowest random number
SET @Upper = 7 ---- One more than the highest random number
SELECT @Random = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)
SELECT @Random

(I did make a slight change to the @Upper- to include the upper number, added 1.)

Here's an example of using the HttpWebRequest class to fetch a URL

private void buttonl_Click(object sender, EventArgs e) 
{ 
    String url = TextBox_url.Text;
    HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url); 
    HttpWebResponse response = (HttpWebResponse) request.GetResponse(); 
    StreamReader sr = new StreamReader(response.GetResponseStream()); 
    richTextBox1.Text = sr.ReadToEnd(); 
    sr.Close(); 
} 

Have a look at this plunker

Autobahn has a good websocket client implementation for Python as well as some good examples. I tested the following with a Tornado WebSocket server and it worked.

from twisted.internet import reactor
from autobahn.websocket import WebSocketClientFactory, WebSocketClientProtocol, connectWS


class EchoClientProtocol(WebSocketClientProtocol):

   def sendHello(self):
      self.sendMessage("Hello, world!")

   def onOpen(self):
      self.sendHello()

   def onMessage(self, msg, binary):
      print "Got echo: " + msg
      reactor.callLater(1, self.sendHello)


if __name__ == '__main__':

   factory = WebSocketClientFactory("ws://localhost:9000")
   factory.protocol = EchoClientProtocol
   connectWS(factory)
   reactor.run()

Your code is in the <head> => runs before the elements are rendered, so document.getElementById('compute'); returns null, as MDN promise...

element = document.getElementById(id);
element is a reference to an Element object, or null if an element with the specified ID is not in the document.

MDN

Solutions:

1. Put the scripts in the bottom of the page.
2. Call the attach code in the load event.
3. Use jQuery library and it's DOM ready event.

What is the jQuery ready event and why is it needed?
(why no just JavaScript's load event):

While JavaScript provides the load event for executing code when a page is rendered, this event does not get triggered until all assets such as images have been completely received. In most cases, the script can be run as soon as the DOM hierarchy has been fully constructed. The handler passed to .ready() is guaranteed to be executed after the DOM is ready, so this is usually the best place to attach all other event handlers...

I was getting this error today. And above answers didn't help me. I was getting this error when I try to start the SQL Server(SQLEXPRESS) service in Services(services.msc).

When I checked the error log at the location C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\Log, there was an entry related TCP/IP port.

2018-06-19 20:41:52.20 spid12s TDSSNIClient initialization failed with error 0x271d, status code 0xa. Reason: Unable to initialize the TCP/IP listener. An attempt was made to access a socket in a way forbidden by its access permissions.

Recently I was running a MSSQLEXPRESS image in my docker container, which was using the same TCP/IP port, that caused this issue.

So, what I did is, I just reset my TCP/IP by doing the below command.

netsh int ip reset resetlog.txt

Once the resetting is done, I had to restart the machine and when I try to start the SQLEXPRESS service again, it started successfully. Hope it helps.

You can use Jasypt to encrypt properties, so you could have your property like this:

db.password=ENC(XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=)

Jasypt allows you to encrypt your properties using different algorithms, once you get the encrypted property you put inside the ENC(...). For instance, you can encrypt this way through Jasypt using the terminal:

encrypted-pwd$ java -cp ~/.m2/repository/org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar  org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="contactspassword" password=supersecretz algorithm=PBEWithMD5AndDES

----ENVIRONMENT-----------------

Runtime: Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 24.45-b08



----ARGUMENTS-------------------

algorithm: PBEWithMD5AndDES
input: contactspassword
password: supersecretz



----OUTPUT----------------------

XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=

To easily configure it with Spring Boot you can use its starter jasypt-spring-boot-starter with group ID com.github.ulisesbocchio

Keep in mind, that you will need to start your application using the same password you used to encrypt the properties. So, you can start your app this way:

mvn -Djasypt.encryptor.password=supersecretz spring-boot:run

Or using the environment variable (thanks to spring boot relaxed binding):

export JASYPT_ENCRYPTOR_PASSWORD=supersecretz
mvn spring-boot:run

You can check below link for more details:

https://www.ricston.com/blog/encrypting-properties-in-spring-boot-with-jasypt-spring-boot/

To use your encrypted properties in your app just use it as usual, use either method you like (Spring Boot wires the magic, anyway the property must be of course in the classpath):

Using @Value annotation

@Value("${db.password}")
private String password;

Or using Environment

@Autowired
private Environment environment;

public void doSomething(Environment env) {
    System.out.println(env.getProperty("db.password"));
}

Update: for production environment, to avoid exposing the password in the command line, since you can query the processes with ps, previous commands with history, etc etc. You could:

• Create a script like this: touch setEnv.sh
• Edit setEnv.sh to export the JASYPT_ENCRYPTOR_PASSWORD variable

  #!/bin/bash

  export JASYPT_ENCRYPTOR_PASSWORD=supersecretz

• Execute the file with . setEnv.sh
• Run the app in background with mvn spring-boot:run &
• Delete the file setEnv.sh
• Unset the previous environment variable with: unset JASYPT_ENCRYPTOR_PASSWORD

document.add(new Paragraph("")) 

It is ineffective above,must add a blank string, like this:

document.add(new Paragraph(" "));

If you have char[] c then you can do char* d = &c[0] and access element c[1] by doing *(d+1), etc.

This is From Fragment class...

((KidsStoryDashboard)getActivity()).values(title_txt,bannerImgUrl);

This Code From Activity Class...

 public void values(String title_txts, String bannerImgUrl) {
    if (!title_txts.isEmpty()) {

//Do something to set text 
    }
    imageLoader.displayImage(bannerImgUrl, htab_header_image, doption);

Put the APK file into the tools folder in the Android SDK and give the path to tools in the command prompt and use the command:

adb install "name".apk file

$rules = [
    "email" => "email|unique:users, email, '.$id.', user_id"
];

In Illuminate\Validation\Rules\Unique;

Unique validation will parse string validation to Rule object

Unique validation has pattern: unique:%s,%s,%s,%s,%s'

Corresponding with: table name, column, ignore, id column, format wheres

/**
 * Convert the rule to a validation string.
 *
 * @return string
 */
public function __toString()
{
    return rtrim(sprintf('unique:%s,%s,%s,%s,%s',
        $this->table,
        $this->column,
        $this->ignore ?: 'NULL',
        $this->idColumn,
        $this->formatWheres()
    ), ',');
}

How about using a drop-in solution like ShareThis or AddThis? They have similar functionality, so it's quite possible they already solved the problem.

AddThis's code has a huge if/else browser version fork for saving favorites, though, with most branches ending in prompting the user to manually add the favorite themselves, so I am thinking that no such pure JavaScript implementation exists.

Otherwise, if you only need to support IE and Firefox, you have IE's window.externalAddFavorite( ) and Mozilla's window.sidebar.addPanel( ).

var appBanners = document.getElementsByClassName('appBanner');

for (var i = 0; i < appBanners.length; i ++) {
    appBanners[i].style.display = 'none';
}

JSFiddle.

You can use the String Element Reference method which is []

Inside the [] can either be a literal substring, an index, or a regex:

> s='abcdefg'
=> "abcdefg"
> s['a']
=> "a"
> s['z']
=> nil

Since nil is functionally the same as false and any substring returned from [] is true you can use the logic as if you use the method .include?:

0> if s[sub_s]
1>    puts "\"#{s}\" has \"#{sub_s}\""
1> else 
1*    puts "\"#{s}\" does not have \"#{sub_s}\""
1> end
"abcdefg" has "abc"

0> if s[sub_s]
1>    puts "\"#{s}\" has \"#{sub_s}\""
1> else 
1*    puts "\"#{s}\" does not have \"#{sub_s}\""
1> end
"abcdefg" does not have "xyz" 

Just make sure you don't confuse an index with a sub string:

> '123456790'[8]    # integer is eighth element, or '0'
=> "0"              # would test as 'true' in Ruby
> '123456790'['8']  
=> nil              # correct

You can also use a regex:

> s[/A/i]
=> "a"
> s[/A/]
=> nil

If you want to return some value then wrap your statement in function

function my_function(){ 

 return my_thing; 
}

Problem is with the statement on the 1st line if you are trying to use PHP

var ask = confirm ('".$message."'); 

IF you are trying to use PHP you should use

 var ask = confirm (<?php echo "'".$message."'" ?>); //now message with be the javascript string!!

It is because there is no package cache in the image, you need to run:

apt-get update

before installing packages, and if your command is in a Dockerfile, you'll then need:

apt-get -y install curl

To suppress the standard output from a command use -qq. E.g.

apt-get -qq -y install curl

Issue related to git commands on Windows operating system:

$ git add --all

warning: LF will be replaced by CRLF in ...

The file will have its original line endings in your working directory.

Resolution:

$ git config --global core.autocrlf false     
$ git add --all 

No any warning messages come up.

It should be quite simple if you are using LogBack or SLF4J. I do it as below

//imports
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

//Initialize logger
Logger logger = LoggerFactory.getLogger(<classname>.class);
try {
   //try something
} catch(Exception e){
   //Actual logging of error
   logger.error("some message", e);
}

Use the following:

/**
* Utility method to replace the string from StringBuilder.
* @param sb          the StringBuilder object.
* @param toReplace   the String that should be replaced.
* @param replacement the String that has to be replaced by.
* 
*/
public static void replaceString(StringBuilder sb,
                                 String toReplace,
                                 String replacement) {      
    int index = -1;
    while ((index = sb.lastIndexOf(toReplace)) != -1) {
        sb.replace(index, index + toReplace.length(), replacement);
    }
}

Use the Unicode Character

I figured it out. Basically it's an async issue. You can't just submit and expect to render the subsequent page immediately. You have to wait until the onLoad event for the next page is triggered. My code is below:

var page = new WebPage(), testindex = 0, loadInProgress = false;

page.onConsoleMessage = function(msg) {
  console.log(msg);
};

page.onLoadStarted = function() {
  loadInProgress = true;
  console.log("load started");
};

page.onLoadFinished = function() {
  loadInProgress = false;
  console.log("load finished");
};

var steps = [
  function() {
    //Load Login Page
    page.open("https://website.com/theformpage/");
  },
  function() {
    //Enter Credentials
    page.evaluate(function() {

      var arr = document.getElementsByClassName("login-form");
      var i;

      for (i=0; i < arr.length; i++) { 
        if (arr[i].getAttribute('method') == "POST") {

          arr[i].elements["email"].value="mylogin";
          arr[i].elements["password"].value="mypassword";
          return;
        }
      }
    });
  }, 
  function() {
    //Login
    page.evaluate(function() {
      var arr = document.getElementsByClassName("login-form");
      var i;

      for (i=0; i < arr.length; i++) {
        if (arr[i].getAttribute('method') == "POST") {
          arr[i].submit();
          return;
        }
      }

    });
  }, 
  function() {
    // Output content of page to stdout after form has been submitted
    page.evaluate(function() {
      console.log(document.querySelectorAll('html')[0].outerHTML);
    });
  }
];


interval = setInterval(function() {
  if (!loadInProgress && typeof steps[testindex] == "function") {
    console.log("step " + (testindex + 1));
    steps[testindex]();
    testindex++;
  }
  if (typeof steps[testindex] != "function") {
    console.log("test complete!");
    phantom.exit();
  }
}, 50);

If your goal is output your array to a string for debbuging: you can use the print_r() function, which receives an expression parameter (your array), and an optional boolean return parameter. Normally the function is used to echo the array, but if you set the return parameter as true, it will return the array impression.

Example:

    //We create a 2-dimension Array as an example
    $ProductsArray = array();

    $row_array['Qty'] = 20;
    $row_array['Product'] = "Cars";

    array_push($ProductsArray,$row_array);

    $row_array2['Qty'] = 30;
    $row_array2['Product'] = "Wheels";

    array_push($ProductsArray,$row_array2);

    //We save the Array impression into a variable using the print_r function
    $ArrayString = print_r($ProductsArray, 1);

    //You can echo the string
    echo $ArrayString;

    //or Log the string into a Log file
    $date = date("Y-m-d H:i:s", time());
    $LogFile = "Log.txt";
    $fh = fopen($LogFile, 'a') or die("can't open file");
    $stringData = "--".$date."\n".$ArrayString."\n";
    fwrite($fh, $stringData);
    fclose($fh);

This will be the output:

Array
(
    [0] => Array
        (
            [Qty] => 20
            [Product] => Cars
        )

    [1] => Array
        (
            [Qty] => 30
            [Product] => Wheels
        )

)

PowerShell 3 supports this out of the box now.

If you're stuck on PowerShell 2, you basically have to use the legacy net use command (as suggested earlier).

For IBM DB2 :

SELECT TYPENAME FROM SYSCAT.COLUMNS WHERE TABSCHEMA='your_schema_name' AND TABNAME='your_table_name' AND COLNAME='your_column_name'

WHERE will filter after the JOIN has occurred.

Filter on the JOIN to prevent rows from being added during the JOIN process.

using Excel = Microsoft.Office.Interop.Excel;
// Your code...
yourWorksheet.Range[yourWorksheet.Cells[rowBegin,colBegin], yourWorksheet.Cells[yourWorksheet.rowEnd, colEnd]].Merge();

Row and Col start at 1.

This is my databdase definition in my docker-compose:

dataBase:
    image: mysql:8.0
    volumes:
        - db_data:/var/lib/mysql
    networks:
        z-net:
            ipv4_address: 172.26.0.2
    restart: always
    entrypoint: ['docker-entrypoint.sh', '--default-authentication-plugin=mysql_native_password']
    environment:
        MYSQL_ROOT_PASSWORD: supersecret
        MYSQL_DATABASE: zdb
        MYSQL_USER: zuser
        MYSQL_PASSWORD: zpass
    ports:
        - "3333:3306"

The relevant line there is entrypoint.

After build and up it, you can test it with:

$ mysql -u zuser -pzpass --host=172.26.0.2  zdb -e "select 1;"

This can happen in more than one scenario, below is a list of well known scenarios :

// calling empty on a function 
empty(myFunction($myVariable)); // the return value of myFunction should be saved into a variable
// then you can use empty on your variable

// using parenthesis to access an element of an array, parenthesis are used to call a function

if (isset($_POST('sms_code') == TRUE ) { ...
// that should be if(isset($_POST['sms_code']) == TRUE)

This also could be triggered when we try to increment the result of a function like below:

$myCounter = '356';

$myCounter = intVal($myCounter)++; // we try to increment the result of the intVal...
// like the first case, the ++ needs to be called on a variable, a variable should hold the the return of the function then we can call ++ operator on it.

In case you have one identity (Id) and one common (Type) columns:

UPDATE #Table1 
SET [Type] = (SELECT TOP 1 [Type]
              FROM #Table1 t              
              WHERE t.[Type] IS NOT NULL AND 
              b.[Id] > t.[Id]
              ORDER BY t.[Id] DESC)
FROM #Table1 b
WHERE b.[Type] IS NULL

You can resize images using CSS just fine if you're modifying an image tag:

<img src="example.png" style="width:2em; height:3em;" />

You cannot scale a background-image property using CSS2, although you can try the CSS3 property background-size.

What you can do, on the other hand, is to nest an image inside a span. See the answer to this question: Stretch and scale CSS background

Here is an example of the wget script in action:

wget -q -O /dev/null "http://example.com/cronjob.php" > /dev/null 2>&1

Using -O parameter like the above means that the output of the web request will be sent to STDOUT (standard output).

And the >/dev/null 2>&1 will instruct standard output to be redirected to a black hole. So no message from the executing program is returned to the screen.

There is no DrawCircle method; use DrawEllipse instead. I have a static class with handy graphics extension methods. The following ones draw and fill circles. They are wrappers around DrawEllipse and FillEllipse:

public static class GraphicsExtensions
{
    public static void DrawCircle(this Graphics g, Pen pen,
                                  float centerX, float centerY, float radius)
    {
        g.DrawEllipse(pen, centerX - radius, centerY - radius,
                      radius + radius, radius + radius);
    }

    public static void FillCircle(this Graphics g, Brush brush,
                                  float centerX, float centerY, float radius)
    {
        g.FillEllipse(brush, centerX - radius, centerY - radius,
                      radius + radius, radius + radius);
    }
}

You can call them like this:

g.FillCircle(myBrush, centerX, centerY, radius);
g.DrawCircle(myPen, centerX, centerY, radius);

You can use jQuery's .text() function.

For example:

http://jsfiddle.net/9H6Ch/

From the jQuery documentation regarding the .text() function:

We need to be aware that this method escapes the string provided as necessary so that it will render correctly in HTML. To do so, it calls the DOM method .createTextNode(), does not interpret the string as HTML.

Previous Versions of the jQuery Documentation worded it this way (emphasis added):

We need to be aware that this method escapes the string provided as necessary so that it will render correctly in HTML. To do so, it calls the DOM method .createTextNode(), which replaces special characters with their HTML entity equivalents (such as &lt; for <).

Yes, a constructor can be private. There are different uses of this. One such use is for the singleton design anti-pattern, which I would advise against you using. Another, more legitimate use, is in delegating constructors; you can have one constructor that takes lots of different options that is really an implementation detail, so you make it private, but then your remaining constructors delegate to it.

As an example of delegating constructors, the following class allows you to save a value and a type, but it only lets you do it for a subset of types, so making the general constructor private is needed to ensure that only the permitted types are used. The common private constructor helps code reuse.

public class MyClass {
     private final String value;
     private final String type;

     public MyClass(int x){
         this(Integer.toString(x), "int");
     }

     public MyClass(boolean x){
         this(Boolean.toString(x), "boolean");
     }

     public String toString(){
         return value;
     }

     public String getType(){
         return type;
     }

     private MyClass(String value, String type){
         this.value = value;
         this.type = type;
     }
}

Edit
Looking at this answer from several years later, I would like to note that this answer is both incomplete and also a little bit extreme. Singletons are indeed an anti-pattern and should generally be avoided where possible; however, there are many uses of private constructors besides singletons, and my answer names only one.

To give a couple more cases where private constructors are used:

1. To create an uninstantiable class that is just a collection of related static functions (this is basically a singleton, but if it is stateless and the static functions operate strictly on the parameters rather than on class state, this is not as unreasonable an approach as my earlier self would seem to suggest, though using an interface that is dependency injected often makes it easier to maintain the API when the implementation requires larger numbers of dependencies or other forms of context).

2. When there are multiple different ways to create the object, a private constructor may make it easier to understand the different ways of constructing it (e.g., which is more readable to you new ArrayList(5) or ArrayList.createWithCapacity(5), ArrayList.createWithContents(5), ArrayList.createWithInitialSize(5)). In other words, a private constructor allows you to provide factory function's whose names are more understandable, and then making the constructor private ensures that people use only the more self-evident names. This is also commonly used with the builder pattern. For example:

   MyClass myVar = MyClass
       .newBuilder()
       .setOption1(option1)
       .setOption2(option2)
       .build();
   

To manually find the minimum of an array you don't need to know the minimum value of float:

float myFloats[];
...
float minimum = myFloats[0];
for (int i = 0; i < myFloatsSize; ++i)
{
  if (myFloats[i] < minimum)
  {
    minimum = myFloats[i];
  }
}

And similar code for the maximum value.

In Java terms, Scala's Seq would be Java's List, and Scala's List would be Java's LinkedList.

Note that Seq is a trait, which is equivalent to Java's interface, but with the equivalent of up-and-coming defender methods. Scala's List is an abstract class that is extended by Nil and ::, which are the concrete implementations of List.

So, where Java's List is an interface, Scala's List is an implementation.

Beyond that, Scala's List is immutable, which is not the case of LinkedList. In fact, Java has no equivalent to immutable collections (the read only thing only guarantees the new object cannot be changed, but you still can change the old one, and, therefore, the "read only" one).

Scala's List is highly optimized by compiler and libraries, and it's a fundamental data type in functional programming. However, it has limitations and it's inadequate for parallel programming. These days, Vector is a better choice than List, but habit is hard to break.

Seq is a good generalization for sequences, so if you program to interfaces, you should use that. Note that there are actually three of them: collection.Seq, collection.mutable.Seq and collection.immutable.Seq, and it is the latter one that is the "default" imported into scope.

There's also GenSeq and ParSeq. The latter methods run in parallel where possible, while the former is parent to both Seq and ParSeq, being a suitable generalization for when parallelism of a code doesn't matter. They are both relatively newly introduced, so people doesn't use them much yet.

You can use:

<input type="number" step="any" min="0" max="100" value="22.33">

This is a really interesting article here. I'm considering implementing JS encryption for offering security when using local storage. It's absolutely clear that this will only offer protection if the device is stolen (and is implemented correctly). It won't offer protection against keyloggers etc. However this is not a JS issue as the keylogger threat is a problem of all applications, regardless of their execution platform (browser, native). As to the article "JavaScript Crypto Considered Harmful" referenced in the first answer, I have one criticism; it states "You could use SSL/TLS to solve this problem, but that's expensive and complicated". I think this is a very ambitious claim (and possibly rather biased). Yes, SSL has a cost, but if you look at the cost of developing native applications for multiple OS, rather than web-based due to this issue alone, the cost of SSL becomes insignificant.

My conclusion - There is a place for client-side encryption code, however as with all applications the developers must recognise it's limitations and implement if suitable for their needs, and ensuring there are ways of mitigating it's risks.

This work for me.

I believe the standard MIME type for Excel files is application/vnd.ms-excel.

Regarding the name of the document, you should set the following header in the response:

header('Content-Disposition: attachment; filename="name_of_excel_file.xls"');

Here are some dplyr options:

You can use systemPropertyVariables (java.protocol.handler.pkgs is your JVM argument name):

Travesal is O(n) for any order - because you are hitting each node once. Lookup is where it can be less than O(n) IF the tree has some sort of organizing schema (ie binary search tree).

To keep it succint and retain all functionality of fs:

const fs = require('fs');
const fsPromises = fs.promises;

async function loadMonoCounter() {
    const data = await fsPromises.readFile('monolitic.txt', 'binary');
    return new Buffer(data);
}

Importing fs and fs.promises separately will give access to the entire fs API while also keeping it more readable... So that something like the next example is easily accomplished.

// the 'next example'
fsPromises.access('monolitic.txt', fs.constants.R_OK | fs.constants.W_OK)
    .then(() => console.log('can access'))
    .catch(() => console.error('cannot access'));

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

So the problem is connected with the metadata errors of elcipse. Go to the metadata folder where this configuration is saved. For me one of the erorrs was that:

SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Document base C:\Users\Cannibal\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\FoodQuantityService does not exist or is not a readable directory

So go there is in the workspace of your eclipse it is different for all and delete all its content . My services was named FoodQuantityService so I deleted all files in org.eclipse.wst.server.core but before that delete your server configuration from Eclipse

Then create new configuration File->New->Other->Server select Tomcat and then projects which you want to be published. Start the server and everything will be ok.

I recently had the same question, and coming from a Java world, I immediately started to search for a JSR 310 implementation for JavaScript. JSR 310 is a Date and Time API for Java (standard shipped as of Java 8). I think the API is very well designed.

Fortunately, there is a direct port to Javascript, called js-joda.

First, include js-joda in the <head>:

<script
    src="https://cdnjs.cloudflare.com/ajax/libs/js-joda/1.11.0/js-joda.min.js"
    integrity="sha512-piLlO+P2f15QHjUv0DEXBd4HvkL03Orhi30Ur5n1E4Gk2LE4BxiBAP/AD+dxhxpW66DiMY2wZqQWHAuS53RFDg=="
    crossorigin="anonymous"></script>

Then simply do this:

let date1 = JSJoda.LocalDate.of(2020, 12, 1);
let date2 = JSJoda.LocalDate.of(2021, 1, 1);
let daysBetween = JSJoda.ChronoUnit.DAYS.between(date1, date2);

Now daysBetween contains the number of days between. Note that the end date is exclusive.

To someone who really understands how JS works this question might seem off, however most people who use JS do not have such a deep level of insight (and don't necessarily need it) and to them this is a fairly confusing point, I will try to answer from that perspective.

JS is synchronous in the way its code is executed. each line only runs after the line before it has completed and if that line calls a function after that is complete etc...

The main point of confusion arises from the fact that your browser is able to tell JS to execute more code at anytime (similar to how you can execute more JS code on a page from the console). As an example JS has Callback functions who's purpose is to allow JS to BEHAVE asynchronously so further parts of JS can run while waiting for a JS function that has been executed (I.E. a GET call) to return back an answer, JS will continue to run until the browser has an answer at that point the event loop (browser) will execute the JS code that calls the callback function.

Since the event loop (browser) can input more JS to be executed at any point in that sense JS is asynchronous (the primary things that will cause a browser to input JS code are timeouts, callbacks and events)

I hope this is clear enough to be helpful to somebody.

There is HTML entity &#10003 but it doesn't work in some older browsers.

In the accepted answer, for Laravel 4 the headers array is constructed incorrectly. Use:

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

The function checks if February has 29 days. If it does, then we have a leap year.

ES5

function isLeap(year) {
  return new Date(year, 1, 29).getDate() === 29;
}

ES6

const isLeap = year => new Date(year, 1, 29).getDate() === 29;

Result

isLeap(1004) // true
isLeap(1001) // false

It's very simple, when you create a new file in VS Code and run it, if you already don't have a configuration file it creates one for you, the only thing you need to setup is the "program" value, and set it to the path of your main JS file, looks like this:

    "version": "0.1.0",
    // List of configurations. Add new configurations or edit existing ones.  
    // ONLY "node" and "mono" are supported, change "type" to switch.

It seems that Xcode really likes to be in the Applications folder and be called Xcode, especially when using xcodebuild (when building for Carthage for example) - and xcode-select doesn't always seem to cut it.

I have a client project that's still using Swift 2.2, and I'm stuck on Xcode 7 for that and using Xcode 8 for anything else.

So, in my Applications folder, I have Xcode 7 (renamed to Xcode_7) and Xcode 8 (renamed to Xcode_8). Then I rename whichever one I need to simply Xcode, and back again when done. It's a ball-ache, but seems to work.

This shell script simplifies it a bit…

xcode-version.sh

cd /Applications

if  [[ $1 = "-8" ]]
then 
    if [ -e Xcode_8.app ] 
    then            
        mv Xcode.app Xcode_7.app
        mv Xcode_8.app Xcode.app
        echo "Switched to Xcode 8"
    else
        echo "Already using Xcode 8"
    fi
elif  [[ $1 = "-7" ]]
then
    if [ -e Xcode_7.app ] 
    then            
        mv Xcode.app Xcode_8.app
        mv Xcode_7.app Xcode.app
        echo "Switched to Xcode 7"
    else
        echo "Already using Xcode 7"
    fi
else
    echo "usage: xcode-version -7/8"
fi

xcode-select --switch Xcode.app

Can't comment yet, but I just wanted to disagree/clarify with erikkallen.

You should not just catch the exception in the situation you've described. If you KNEW that the file should be there and due to some exceptional case, it wasn't, then it would be acceptable to just attempt to access the file and catch any exception that occurs.

In this case, however, you are receiving input from a user and have little reason to believe that the file exists. Here you should always use File.Exists().

I know it is cliché, but you should only use Exceptions for an exceptional event, not as part as the normal flow of your application. It is expensive and makes code more difficult to read/follow.

Toggle function in react

At first you should create constructor like this

constructor(props) {
        super(props);
        this.state = {
            close: true,
        };
    }

Then create a function like this

yourFunction = () => {
        this.setState({
            close: !this.state.close,
        });
    };

then use this like

render() {
        const {close} = this.state;
        return (

            <Fragment>

                 <div onClick={() => this.yourFunction()}></div>

                 <div className={close ? "isYourDefaultClass" : "isYourOnChangeClass"}></div>

            </Fragment>
        )
    }
}

Please give better solutions

A portable solution could use getc.

#include <stdio.h>

char buffer[MAX_FILE_SIZE];
size_t i;

for (i = 0; i < MAX_FILE_SIZE; ++i)
{
    int c = getc(fp);

    if (c == EOF)
    {
        buffer[i] = 0x00;
        break;
    }

    buffer[i] = c;
}

If you don't want to have a MAX_FILE_SIZE macro or if it is a big number (such that buffer would be to big to fit on the stack), use dynamic allocation.

Since you're using Spring Boot, I assume you'd prefer to rely on Spring's auto configuration where possible. To add additional custom configuration like your interceptors, just provide a configuration or bean of WebMvcConfigurerAdapter.

Here's an example of a config class:

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

  @Autowired 
  HandlerInterceptor yourInjectedInterceptor;

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(...)
    ...
    registry.addInterceptor(getYourInterceptor()); 
    registry.addInterceptor(yourInjectedInterceptor);
    // next two should be avoid -- tightly coupled and not very testable
    registry.addInterceptor(new YourInterceptor());
    registry.addInterceptor(new HandlerInterceptor() {
        ...
    });
  }
}

NOTE do not annotate this with @EnableWebMvc, if you want to keep Spring Boots auto configuration for mvc.

Here's a better option:

git remote set-head -a origin

From the documentation:

With -a, the remote is queried to determine its HEAD, then $GIT_DIR/remotes//HEAD is set to the same branch. e.g., if the remote HEAD is pointed at next, "git remote set-head origin -a" will set $GIT_DIR/refs/remotes/origin/HEAD to refs/remotes/origin/next. This will only work if refs/remotes/origin/next already exists; if not it must be fetched first.

This has actually been around quite a while (since v1.6.3); not sure how I missed it!

Revert is the command to rollback the commits.

git revert <commit1> <commit2> 

Sample:

git revert 2h3h23233

It is capable of taking range from the HEAD like below. Here 1 says "revert last commit."

git revert HEAD~1..HEAD

and then do git push

If you have jQuery enabled you can use an escapeXml function and not have to worry about escaping arrows or special characters.

<pre>
  ${fn:escapeXml('
    <!-- all your code -->

From a comment:

I want to sort each set.

That's easy. For any set s (or anything else iterable), sorted(s) returns a list of the elements of s in sorted order:

>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']

Note that sorted is giving you a list, not a set. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2} and {2, 1} are the same set.

You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).

The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key function:

>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']

For more information, see the Sorting HOWTO in the official docs.

Public Service Announcement:

I want to state for the record that I believe traits are almost always a code smell and should be avoided in favor of composition. It's my opinion that single inheritance is frequently abused to the point of being an anti-pattern and multiple inheritance only compounds this problem. You'll be much better served in most cases by favoring composition over inheritance (be it single or multiple). If you're still interested in traits and their relationship to interfaces, read on ...

Let's start by saying this:

Object-Oriented Programming (OOP) can be a difficult paradigm to grasp. Just because you're using classes doesn't mean your code is Object-Oriented (OO).

To write OO code you need to understand that OOP is really about the capabilities of your objects. You've got to think about classes in terms of what they can do instead of what they actually do. This is in stark contrast to traditional procedural programming where the focus is on making a bit of code "do something."

If OOP code is about planning and design, an interface is the blueprint and an object is the fully constructed house. Meanwhile, traits are simply a way to help build the house laid out by the blueprint (the interface).

Interfaces

So, why should we use interfaces? Quite simply, interfaces make our code less brittle. If you doubt this statement, ask anyone who's been forced to maintain legacy code that wasn't written against interfaces.

The interface is a contract between the programmer and his/her code. The interface says, "As long as you play by my rules you can implement me however you like and I promise I won't break your other code."

So as an example, consider a real-world scenario (no cars or widgets):

You want to implement a caching system for a web application to cut down on server load

You start out by writing a class to cache request responses using APC:

class ApcCacher
{
  public function fetch($key) {
    return apc_fetch($key);
  }
  public function store($key, $data) {
    return apc_store($key, $data);
  }
  public function delete($key) {
    return apc_delete($key);
  }
}

Then, in your HTTP response object, you check for a cache hit before doing all the work to generate the actual response:

class Controller
{
  protected $req;
  protected $resp;
  protected $cacher;

  public function __construct(Request $req, Response $resp, ApcCacher $cacher=NULL) {
    $this->req    = $req;
    $this->resp   = $resp;
    $this->cacher = $cacher;

    $this->buildResponse();
  }

  public function buildResponse() {
    if (NULL !== $this->cacher && $response = $this->cacher->fetch($this->req->uri()) {
      $this->resp = $response;
    } else {
      // Build the response manually
    }
  }

  public function getResponse() {
    return $this->resp;
  }
}

This approach works great. But maybe a few weeks later you decide you want to use a file-based cache system instead of APC. Now you have to change your controller code because you've programmed your controller to work with the functionality of the ApcCacher class rather than to an interface that expresses the capabilities of the ApcCacher class. Let's say instead of the above you had made the Controller class reliant on a CacherInterface instead of the concrete ApcCacher like so:

// Your controller's constructor using the interface as a dependency
public function __construct(Request $req, Response $resp, CacherInterface $cacher=NULL)

To go along with that you define your interface like so:

interface CacherInterface
{
  public function fetch($key);
  public function store($key, $data);
  public function delete($key);
}

In turn you have both your ApcCacher and your new FileCacher classes implement the CacherInterface and you program your Controller class to use the capabilities required by the interface.

This example (hopefully) demonstrates how programming to an interface allows you to change the internal implementation of your classes without worrying if the changes will break your other code.

Traits

Traits, on the other hand, are simply a method for re-using code. Interfaces should not be thought of as a mutually exclusive alternative to traits. In fact, creating traits that fulfill the capabilities required by an interface is the ideal use case.

You should only use traits when multiple classes share the same functionality (likely dictated by the same interface). There's no sense in using a trait to provide functionality for a single class: that only obfuscates what the class does and a better design would move the trait's functionality into the relevant class.

Consider the following trait implementation:

interface Person
{
    public function greet();
    public function eat($food);
}

trait EatingTrait
{
    public function eat($food)
    {
        $this->putInMouth($food);
    }

    private function putInMouth($food)
    {
        // Digest delicious food
    }
}

class NicePerson implements Person
{
    use EatingTrait;

    public function greet()
    {
        echo 'Good day, good sir!';
    }
}

class MeanPerson implements Person
{
    use EatingTrait;

    public function greet()
    {
        echo 'Your mother was a hamster!';
    }
}

A more concrete example: imagine both your FileCacher and your ApcCacher from the interface discussion use the same method to determine whether a cache entry is stale and should be deleted (obviously this isn't the case in real life, but go with it). You could write a trait and allow both classes to use it to for the common interface requirement.

One final word of caution: be careful not to go overboard with traits. Often traits are used as a crutch for poor design when unique class implementations would suffice. You should limit traits to fulfilling interface requirements for best code design.

The font sizes in your question are an example of what ratio each header should be in comparison to each other, rather than what size they should be themselves (in pixels).

So in response to your question "Is there a 'best practice' for these for mobile phones? - say iphone screen size?", yes there probably is - but you might find what someone says is "best practice" does not work for your layout.

However, to help get you on the right track, this article about building responsive layouts provides a good example of how to calculate the base font-size in pixels in relation to device screen sizes.

The suggested font-sizes for screen resolutions suggested from that article are as follows:

@media (min-width: 858px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 780px) {
    html {
        font-size: 11px;
    }
}

@media (min-width: 702px) {
    html {
        font-size: 10px;
    }
}

@media (min-width: 724px) {
    html {
        font-size: 9px;
    }
}

@media (max-width: 623px) {
    html {
        font-size: 8px;
    }
}

Source code:

   public long fileSize(File root) {
        if(root == null){
            return 0;
        }
        if(root.isFile()){
            return root.length();
        }
        try {
            if(isSymlink(root)){
                return 0;
            }
        } catch (IOException e) {
            e.printStackTrace();
            return 0;
        }

        long length = 0;
        File[] files = root.listFiles();
        if(files == null){
            return 0;
        }
        for (File file : files) {
            length += fileSize(file);
        }

        return length;
    }

    private static boolean isSymlink(File file) throws IOException {
        File canon;
        if (file.getParent() == null) {
            canon = file;
        } else {
            File canonDir = file.getParentFile().getCanonicalFile();
            canon = new File(canonDir, file.getName());
        }
        return !canon.getCanonicalFile().equals(canon.getAbsoluteFile());
    }

I resolved this by just running a simple:

git pull

Nothing more. Now it's showing:

# On branch master
nothing to commit, working directory clean

Have you try first remove duplicates in the subquery?

INSERT INTO destTable
SELECT source.* FROM(
    SELECT *
    FROM srcTable
    EXCEPT
    SELECT src.* FROM
    srcTable AS src
    INNER JOIN destTable AS dest 
    /* put in below line the conditions to match repeated registers */
        ON dest.SOME_FANCY_MATCH = src.SOME_FANCY_MATCH AND ... 
) as source

If the sets are very large, maybe this is not the best solution.

If you want to do it using XAML set the property isReadOnly to true.

Default

The default Gson implementation of Map serialization uses toString() on the key:

Gson gson = new GsonBuilder()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will give:

{
  "java.awt.Point[x\u003d1,y\u003d2]": "a",
  "java.awt.Point[x\u003d3,y\u003d4]": "b"
}

Using enableComplexMapKeySerialization

If you want the Map Key to be serialized according to default Gson rules you can use enableComplexMapKeySerialization. This will return an array of arrays of key-value pairs:

Gson gson = new GsonBuilder().enableComplexMapKeySerialization()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will return:

[
  [
    {
      "x": 1,
      "y": 2
    },
    "a"
  ],
  [
    {
      "x": 3,
      "y": 4
    },
    "b"
  ]
]

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

One of the disadvantages of using HTML for labels is when you need to write a localizable program (which should work in several languages). You will have issues to change just the translatable text. Or you will have to put the whole HTML code into your translations which is very awkward, I would even say absurd :)

gui_en.properties:

title.text=<html>Text color: <font color='red'>red</font></html>

gui_fr.properties:

title.text=<html>Couleur du texte: <font color='red'>rouge</font></html>

gui_ru.properties:

title.text=<html>???? ??????: <font color='red'>???????</font></html>

Dynamic cached find

In this solution, when we search for some object, we save it in cache. This is middle point between "always search solutions" and "create hash-map for each object in precalculations".

let cachedFind = (()=>{
  let cache = new Map();
  return (arr,id,el=null) => 
    cache.get(id) || (el=arr.find(o=> o.id==id), cache.set(id,el), el);
})();


// ---------
// TEST
// ---------

let myArray = [...Array(100000)].map((x,i)=> ({'id':`${i}`, 'foo':`bar_${i}`}));

// example usage

console.log( cachedFind(myArray,'1234').foo );





// Benchmark

let bench = (id) => {
  console.time   ('time for '+id ); 
  console.log    ( cachedFind(myArray,id).foo );  // FIND
  console.timeEnd('time for '+id );
}

console.log('----- no cached -----');
bench(50000);
bench(79980);
bench(99990);
console.log('-----  cached   -----');
bench(79980); // cached
bench(99990); // cached

I prefer String.join(list) in Java 8
