Operators Overloadability
+, -, *, /, %, &, |, <<, >> All C# binary operators can be overloaded.
+, -, !, ~, ++, --, true, false All C# unary operators can be overloaded.
==, !=, <, >, <= , >= All relational operators can be overloaded,
but only as pairs.
&&, || They can't be overloaded
() (Conversion operator) They can't be overloaded
+=, -=, *=, /=, %= These compound assignment operators can be
overloaded. But in C#, these operators are
automatically overloaded when the respective
binary operator is overloaded.
=, . , ?:, ->, new, is, as, sizeof These operators can't be overloaded
[ ] Can be overloaded but not always!
For bracket:
public Object this[int index]
{
}
The array indexing operator cannot be overloaded; however, types can define indexers, properties that take one or more parameters. Indexer parameters are enclosed in square brackets, just like array indices, but indexer parameters can be declared to be of any type (unlike array indices, which must be integral).

JSDoc 3 allows you to annotate your functions with the @access private
(previously the @private
tag) which is also useful for broadcasting your intent to other developers - http://usejsdoc.org/tags-access.html
For Python3+ URLopener
is deprecated.
And when used you will get error as below:
url_opener = urllib.URLopener() AttributeError: module 'urllib' has no attribute 'URLopener'
So, try:
import urllib.request
urllib.request.urlretrieve(url, filename)
It's as easy as using select:
Get-Content file.txt | Select -Index (line - 1)
E.g. to get line 5
Get-Content file.txt | Select -Index 4
Or you can use:
(Get-Content file.txt)[4]
Addressing Steven's comment to Sam Dufel's answer
Thanks, sounds like that's the way to go. But I just realized that I only want the optional whitespace characters if they follow a newline. So for example, "c\n ats" or "ca\n ts" should match. But wouldn't want "c ats" to match if there is no newline. Any ideas on how that might be done?
This should do the trick:
/c(?:\n\s*)?a(?:\n\s*)?t(?:\n\s*)?s/
See this page for all the different variations of 'cats' that this matches.
You can also solve this using conditionals, but they are not supported in the javascript flavor of regex.
In this example ordering adds no information - the COUNT of a set is the same whatever order it is in!
If you were selecting something that did depend on order, you would need to do one of the things the error message tells you - use TOP or FOR XML
If you specifically want to use an ad hoc wireless network, then Andy's answer seems to be your only option. However, if you just want to share your laptop's internet connection via Wi-fi using any means necessary, then you have at least two more options:
*Some phones with Android 2.3 have proprietary OS extensions that enable Wi-fi Direct (mostly newer Samsung phones), but Android 4 should fully support this (source).
Posting this in an effort to help others with similar problems. I solved this issue with a five step approach -- save the context, translate the context, rotate the context, draw the text, then restore the context to its saved state.
I think of translations and transforms to the context as manipulating the coordinate grid overlaid on the canvas. By default the origin (0,0) starts in the upper left hand corner of the canvas. X increases from left to right, Y increases from top to bottom. If you make an "L" w/ your index finger and thumb on your left hand and hold it out in front of you with your thumb down, your thumb would point in the direction of increasing Y and your index finger would point in the direction of increasing X. I know it's elementary, but I find it helpful when thinking about translations and rotations. Here's why:
When you translate the context, you move the origin of the coordinate grid to a new location on the canvas. When you rotate the context, think of rotating the "L" you made with your left hand in a clockwise direction the amount indicated by the angle you specify in radians about the origin. When you strokeText or fillText, specify your coordinates in relation to the newly aligned axes. To orient your text so it's readable from bottom to top, you would translate to a position below where you want to start your labels, rotate by -90 degrees and fill or strokeText, offsetting each label along the rotated x axis. Something like this should work:
context.save();
context.translate(newx, newy);
context.rotate(-Math.PI/2);
context.textAlign = "center";
context.fillText("Your Label Here", labelXposition, 0);
context.restore();
.restore() resets the context back to the state it had when you called .save() -- handy for returning things back to "normal".
You can use >>
to print in another file.
echo "hello" >> logfile.txt
Use the equals
method. Why are you so worried that it's expensive?
For Java 7+, there is also https://docs.oracle.com/javase/7/docs/api/java/nio/file/DirectoryStream.html
Example taken from the Javadoc:
List<Path> listSourceFiles(Path dir) throws IOException {
List<Path> result = new ArrayList<>();
try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir, "*.{c,h,cpp,hpp,java}")) {
for (Path entry: stream) {
result.add(entry);
}
} catch (DirectoryIteratorException ex) {
// I/O error encounted during the iteration, the cause is an IOException
throw ex.getCause();
}
return result;
}
How about if you're copying each column in a sheet to different sheets? Example: row B of mysheet to row B of sheet1, row C of mysheet to row B of sheet 2...

--version
is a valid option from JDK 9 and it is not a valid option until JDK 8 hence you get the below:
Unrecognized option: --version
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
You can try installing JDK 9 or any version later and check for java --version
it will work.
Alternately, from the installed JDK 9 or later versions you can see from java -help
the below two options will be available:
-version print product version to the error stream and exit
--version print product version to the output stream and exit
where as in JDK 8 you will only have below when you execute java -help
-version print product version and exit
I hope it answers your question.
const int*
- pointer to constant int
object.You can change the value of the pointer; you can not change the value of the int
object, the pointer points to.
const int * const
- constant pointer to constant int
object.You can not change the value of the pointer nor the value of the int
object the pointer points to.
int const *
- pointer to constant int
object.This statement is equivalent to 1. const int*
- You can change the value of the pointer but you can not change the value of the int
object, the pointer points to.
Actually, there is a 4th option:
int * const
- constant pointer to int
object.You can change the value of the object the pointer points to but you can not change the value of the pointer itself. The pointer will always point to the same int
object but this value of this int
object can be changed.
If you want to determine a certain type of C or C++ construct you can use the Clockwise/Spiral Rule made by David Anderson; but not to confuse with Anderson`s Rule made by Ross J. Anderson, which is something quite distinct.
From here (Google is your friend):
In a DTD, PCDATA and CDATA are used to assert something about the allowable content of elements and attributes, respectively. In an element's content model, #PCDATA says that the element contains (may contain) "any old text." (With exceptions as noted below.) In an attribute's declaration, CDATA is one sort of constraint you can put on the attribute's allowable values (other sorts, all mutually exclusive, include ID, IDREF, and NMTOKEN). An attribute whose allowable values are CDATA can (like PCDATA in an element) contain "any old text."
A potentially really confusing issue is that there's another "CDATA," also referred to as marked sections. A marked section is a portion of element (#PCDATA) content delimited with special strings: to close it. If you remember that PCDATA is "parsed character data," a CDATA section is literally the same thing, without the "parsed." Parsers transmit the content of a marked section to downstream applications without hiccupping every time they encounter special characters like < and &. This is useful when you're coding a document that contains lots of those special characters (like scripts and code fragments); it's easier on data entry, and easier on reading, than the corresponding entity reference.
So you can infer that the exception to the "any old text" rule is that PCDATA cannot include any of these unescaped special characters, UNLESS they fall within the scope of a CDATA marked section.
Who needs distributed, sharded forums? Maybe Facebook, but unless you're creating a Facebook-competitor, just use Mysql, Postgres or whatever you are most comfortable with. If you want to try MongoDB, ok, but don't expect it to do magic for you. It'll have its quirks and general nastiness, just as everything else, as I'm sure you've already discovered if you really have been working on it already.
Sure, MongoDB may be hyped and seem easy on the surface, but you'll run into problems which more mature products have already overcome. Don't be lured so easily, but rather wait until "nosql" matures, or dies.
Personally, I think "nosql" will wither and die from fragmentation, as there are no set standards (almost by definition). So I will not personally bet on it for any long-term projects.
Only thing that can save "nosql" in my book, is if it can integrate into Ruby or similar languages seamlessly, and make the language "persistent", almost without any overhead in coding and design. That may come to pass, but I'll wait until then, not now, AND it needs to be more mature of course.
Btw, why are you creating a forum from scratch? There are tons of open source forums which can be tweaked to fit most requirements, unless you really are creating The Next Generation of Forums (which I doubt).
Nice answers. You could also set Jobs (i.e., commands) with "Crontab" for more flexibility (which provides different options to run scripts, loggin the outputs, etc.), although it requires more time to be understood and set properly:
Using '@reboot' you can Run a command once, at startup.
Wrapping up:
run $ sudo crontab -e -u root
And add a line at the end of the file with your command as follows:
@reboot sudo searchd
You need to create a new Font
mainForm.lblName.Font = new Font("Arial", mainForm.lblName.Font.Size);
The properties on the style
object are only the styles applied directly to the element (e.g., via a style
attribute or in code). So .style.marginTop
will only have something in it if you have something specifically assigned to that element (not assigned via a style sheet, etc.).
To get the current calculated style of the object, you use either the currentStyle
property (Microsoft) or the getComputedStyle
function (pretty much everyone else).
Example:
var p = document.getElementById("target");
var style = p.currentStyle || window.getComputedStyle(p);
display("Current marginTop: " + style.marginTop);
Fair warning: What you get back may not be in pixels. For instance, if I run the above on a p
element in IE9, I get back "1em"
.
The accepted answer is out of date; nowadays you can simply add enctype="application/json"
to your form tag and the browser will jsonify the data automatically.
The spec for this behavior is here: https://www.w3.org/TR/html-json-forms/
According to git stash questions, after fixing the conflict, git add <file>
is the right course of action.
It was after reading this comment that I understood that the changes are automatically added to the index (by design). That's why git add <file>
completes the conflict resolution process.
don't uninstall anything. a system with multiple versions of java works just fine. and you don't need to update your environment varables (e.g. java_home, path, etc..).
yes, ireports 3.6.1 needs java 7 (doesn't work with java 8).
all you have to do is edit C:\Program Files\Jaspersoft\iReport-nb-3.6.1\etc\ireport.conf:
# default location of JDK/JRE, can be overridden by using --jdkhome <dir> switch
jdkhome="C:/Program Files/Java/jdk1.7.0_45"
on linux (no spaces and standard file paths) its that much easier. keep your java 8 for other interesting projects...
In MonoDroid / Xamarin.Android you can do:
var resourceId = Resources.GetIdentifier("icon", "drawable", PackageName);
But since GetIdentifier it's not recommended in Android - you can use Reflection like this:
var resourceId = (int)typeof(Resource.Drawable).GetField("icon").GetValue(null);
where I suggest to put a try/catch or verify the strings you are passing.
If you have couple of json files:
import data from 'sample.json';
If you were to dynamically load one of the many json file, you might have to use a fetch
instead:
fetch(`${fileName}.json`)
.then(response => response.json())
.then(data => console.log(data))
As an alternative (if you don't want to use background), you can easily do it by making a view as follows:
<View
android:layout_width="2dp"
android:layout_height="match_parent"
android:background="#000000" />
For having a right border only, place this after the layout (where you want to have the border):
<View
android:layout_width="2dp"
android:layout_height="match_parent"
android:background="#000000" />
For having a left border only, place this before the layout (where you want to have the border):
Worked for me...Hope its of some help....
I don't think you're going to get much faster than dd. The bottleneck is the disk; writing hundreds of GB of data to it is going to take a long time no matter how you do it.
But here's a possibility that might work for your application. If you don't care about the contents of the file, how about creating a "virtual" file whose contents are the dynamic output of a program? Instead of open()ing the file, use popen() to open a pipe to an external program. The external program generates data whenever it's needed. Once the pipe is open, it acts just like a regular file in that the program that opened the pipe can fseek(), rewind(), etc. You'll need to use pclose() instead of close() when you're done with the pipe.
If your application needs the file to be a certain size, it will be up to the external program to keep track of where in the "file" it is and send an eof when the "end" has been reached.
You may use combination of TimerDispatcher (WPF Timer analog) and Windows "Hooks" to catch cursor position from operational system.
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetCursorPos(out POINT pPoint);
Point is a light struct
. It contains only X, Y fields.
public MainWindow()
{
InitializeComponent();
DispatcherTimer dt = new System.Windows.Threading.DispatcherTimer();
dt.Tick += new EventHandler(timer_tick);
dt.Interval = new TimeSpan(0,0,0,0, 50);
dt.Start();
}
private void timer_tick(object sender, EventArgs e)
{
POINT pnt;
GetCursorPos(out pnt);
current_x_box.Text = (pnt.X).ToString();
current_y_box.Text = (pnt.Y).ToString();
}
public struct POINT
{
public int X;
public int Y;
public POINT(int x, int y)
{
this.X = x;
this.Y = y;
}
}
This solution is also resolving the problem with too often or too infrequent parameter reading so you can adjust it by yourself. But remember about WPF method overload with one arg which is representing ticks
not milliseconds
.
TimeSpan(50); //ticks
You're talking about template literals.
They allow for both multiline strings and string interpolation.
Multiline strings:
console.log(`foo_x000D_
bar`);_x000D_
// foo_x000D_
// bar
_x000D_
String interpolation:
var foo = 'bar';_x000D_
console.log(`Let's meet at the ${foo}`);_x000D_
// Let's meet at the bar
_x000D_
First you need to create a mock m_contractsDao and set it up. Assuming that the class is ContractsDao:
ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(any(String.class))).thenReturn("Some result");
Then inject the mock into m_orderSvc and call your method.
m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work();
Finally, verify that the mock was called properly:
verify(mock_contractsDao, times(1)).save("Parameter I'm expecting");
Visual Studio 2015:

Your Application Properties
. Each argument can be separated using space. If you have a space in between for the same argument, put double quotes as shown in the example below.
static void Main(string[] args)
{
if(args == null || args.Length == 0)
{
Console.WriteLine("Please specify arguments!");
}
else
{
Console.WriteLine(args[0]); // First

}
}
yes you can
DataGridView1.Rows[0].HeaderCell.Value = "my text";
You need to specify a type on person:
void addStudent(struct student person) {
...
}
Also, you can typedef your struct to avoid having to type struct every time you use it:
typedef struct student{
...
} student_t;
void addStudent(student_t person) {
...
}
Jeet's answer works in PowerShell.
git grep -n <regex> $(git rev-list --all)
The following displays all files, in any commit, that contain a password
.
# Store intermediate result
$result = git grep -n "password" $(git rev-list --all)
# Display unique file names
$result | select -unique { $_ -replace "(^.*?:)|(:.*)", "" }
First of all convert your set to Array. Then, get item by index of array .
Set uniqueItem = new HashSet() ;
uniqueItem.add("0");
uniqueItem.add("1");
uniqueItem.add("0");
Object[] arrayItem = uniqueItem.toArray();
for(int i = 0; i < uniqueItem.size();i++){
System.out.println("Item "+i+" "+arrayItem[i].toString());
}
You can not do that...
via css the URL
you put on the background-image
is just for the image.
Via HTML
you have to add the href
for your hyperlink in this way:
<a href="http://home.com" id="logo">Your logo</a>
With text-indent
and some other css
you can adjust your a element to show just the image and clicking on it you will go to your link.
EDIT:
I'm here again to show you and explain why my solution is much better:
<a href="http://home.com" id="logo">Your logo name</a>
This block of HTML
is SEO friendly because you have some text inside your link!
How to style it with css:
#logo {
background-image: url(images/logo.png);
display: block;
margin: 0 auto;
text-indent: -9999px;
width: 981px;
height: 180px;
}
Then if you don't care about SEO good to choose the other answer.
util.format does this.
It will be part of v0.5.3 and can be used like this:
var uri = util.format('http%s://%s%s',
(useSSL?'s':''), apiBase, path||'/');
I use date.js. It handles this easily and takes care of all the leap-year nastiness.
Expanding on Tony's answer, and also answering Dhaval Ptl's question, to get the true accordion effect and only allow one row to be expanded at a time, an event handler for show.bs.collapse can be added like so:
$('.collapse').on('show.bs.collapse', function () {
$('.collapse.in').collapse('hide');
});
I modified his example to do this here: http://jsfiddle.net/QLfMU/116/
In cases wherein the width/height of the space is beyond
I usually use:
For horizontal spacer:
<span style="display:inline-block; width: YOURWIDTH;"></span>
For vertical spacer:
<span style="display:block; height: YOURHEIGHT;"></span>
I use colordiff.
On Mac OS X, install it with
$ sudo port install colordiff
On Linux is possibly apt get install colordiff
or something like that, depending on your distro.
Then:
$ git difftool --extcmd="colordiff -ydw" HEAD^ HEAD
Or create an alias
$ git alias diffy "difftool --extcmd=\"colordiff -ydw\""
Then you can use it
$ git diffy HEAD^ HEAD
I called it "diffy" because diff -y
is the side-by-side diff in unix. Colordiff also adds colors, that are nicer.
In the option -ydw
, the y
is for the side-by-side, the w
is to ignore whitespaces, and the d
is to produce the minimal diff (usually you get a better result as diff)
I'm didn't totally follow, but to add an action listener, you just call addActionListener (from Abstract Button). If this doesn't totally answer your question, can you provide some more details?
My favoured technique:
signal clk : std_logic := '0'; -- make sure you initialise!
...
clk <= not clk after half_period;
I usually extend this with a finished
signal to allow me to stop the clock:
clk <= not clk after half_period when finished /= '1' else '0';
Gotcha alert:
Care needs to be taken if you calculate half_period
from another constant by dividing by 2. The simulator has a "time resolution" setting, which often defaults to nanoseconds... In which case, 5 ns / 2
comes out to be 2 ns
so you end up with a period of 4ns! Set the simulator to picoseconds and all will be well (until you need fractions of a picosecond to represent your clock time anyway!)
for executing that you must provide full path of that for example
/home/Manuel/mywrittenscript
This is 2 step process
If you want to push your branch code to remote repo then do
Since id is an attribute don't create an id element, just do this:
myPara.setAttribute("id", "id_you_like");
The problem for me was that I was using a response.blob() to populate the form data. Apparently you can't do that at least with react native so I ended up using
data.append('fileData', {
uri : pickerResponse.uri,
type: pickerResponse.type,
name: pickerResponse.fileName
});
Fetch seems to recognize that format and send the file where the uri is pointing.
I had a similar requirement in the app I am working on. And, I found a third-party library which does a slide-up, slide-down and slide-right in Android.
Refer to the link for more details: https://github.com/mancj/SlideUp-Android
To set up the library(copied from the ReadMe portion of its Github page on request):
Get SlideUp library
Add the JitPack repository to your build file. Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
maven { url "https://maven.google.com" } // or google() in AS 3.0
}
}
Add the dependency (in the Module gradle)
dependencies {
compile 'com.github.mancj:SlideUp-Android:2.2.1'
compile 'ru.ztrap:RxSlideUp2:2.x.x' //optional, for reactive listeners based on RxJava-2
compile 'ru.ztrap:RxSlideUp:1.x.x' //optional, for reactive listeners based on RxJava
}
To add the SlideUp into your project, follow these three simple steps:
Step 1:
create any type of layout
<LinearLayout
android:id="@+id/slideView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Step 2:
Find that view in your activity/fragment
View slideView = findViewById(R.id.slideView);
Step 3:
Create a SlideUp object and pass in your view
slideUp = new SlideUpBuilder(slideView)
.withStartState(SlideUp.State.HIDDEN)
.withStartGravity(Gravity.BOTTOM)
//.withSlideFromOtherView(anotherView)
//.withGesturesEnabled()
//.withHideSoftInputWhenDisplayed()
//.withInterpolator()
//.withAutoSlideDuration()
//.withLoggingEnabled()
//.withTouchableAreaPx()
//.withTouchableAreaDp()
//.withListeners()
//.withSavedState()
.build();
You may also refer to the sample project on the link. I found it quite useful.
This worked for me, use the VM args in NetBeans:
@Value("${a.b.c:#{abc}}"
...
@Value("${e.f.g:#{efg}}"
...
Netbeans:
-Da.b.c="..." -De.f.g="..."
Properties -> Run -> VM Options -> -De.f.g=efg -Da.b.c=abc
From the commandline
java -jar <yourjar> --Da.b.c="abc"
.NET Core will install and run on macOS - and just about any other desktop OS.
IDEs are available for the mac, including:
Mono is a good option that I've used in the past. But with Core 3.0 out now, I would go that route.
I needed a solution for this issue as well and I used the answers in this thread to come up with the following:
.directive('tpReport', ['$parse', '$http', '$compile', '$templateCache', function($parse, $http, $compile, $templateCache)
{
var getTemplateUrl = function(type)
{
var templateUrl = '';
switch (type)
{
case 1: // Table
templateUrl = 'modules/tpReport/directives/table-report.tpl.html';
break;
case 0:
templateUrl = 'modules/tpReport/directives/default.tpl.html';
break;
default:
templateUrl = '';
console.log("Type not defined for tpReport");
break;
}
return templateUrl;
};
var linker = function (scope, element, attrs)
{
scope.$watch('data', function(){
var templateUrl = getTemplateUrl(scope.data[0].typeID);
var data = $templateCache.get(templateUrl);
element.html(data);
$compile(element.contents())(scope);
});
};
return {
controller: 'tpReportCtrl',
template: '<div>{{data}}</div>',
// Remove all existing content of the directive.
transclude: true,
restrict: "E",
scope: {
data: '='
},
link: linker
};
}])
;
Include in your html:
<tp-report data='data'></tp-report>
This directive is used for dynamically loading report templates based on the dataset retrieved from the server.
It sets a watch on the scope.data property and whenever this gets updated (when the users requests a new dataset from the server) it loads the corresponding directive to show the data.

So it seems if we measure 1 running loop cycle like timeit.timeit("[x for x in range(1000000) if x%4]",number=1) (as we actually use in real code) python3 works quick enough, but in repeated loops python 2 xrange() wins in speed against range() from python 3.
calling select
will result is lazy
evaluation: for example:
val df1 = df.select("col1")
val df2 = df1.filter("col1 == 3")
both above statements create lazy path that will be executed when you call action on that df
, such as show
, collect
etc.
val df3 = df2.collect()

I was recently facing the same problem. This Error was showing on my screen after running my project main file. Error:java: invalid source release: 11 Follow the steps to resolve this error
After running You will see error is resolved..
You can see it's work perfectly.. Please approach me If you find any problem
You could use this library http://www.stacktracejs.com/ . It's very good
From documentation
You can also pass in your own Error to get a stacktrace not available in IE or Safari 5-
<script type="text/javascript" src="https://rawgithub.com/stacktracejs/stacktrace.js/master/stacktrace.js"></script>
<script type="text/javascript">
try {
// error producing code
} catch(e) {
var trace = printStackTrace({e: e});
alert('Error!\n' + 'Message: ' + e.message + '\nStack trace:\n' + trace.join('\n'));
// do something else with error
}
</script>
For the current branch, you could also say git checkout
(w/o any branch). This is a no-op with a side-effects to show the tracking information, if exists, for the current branch.
$ git checkout
Your branch is up-to-date with 'origin/master'.
You need to have better understanding of the python language and its standard library to translate the expression
cat "$filename": Reads the file cat "$filename"
and dumps the content to stdout
|
: pipe redirects the stdout
from previous command and feeds it to the stdin
of the next command
grep "something": Searches the regular expressionsomething
plain text data file (if specified) or in the stdin and returns the matching lines.
cut -d'"' -f2: Splits the string with the specific delimiter and indexes/splices particular fields from the resultant list
Python Equivalent
cat "$filename" | with open("$filename",'r') as fin: | Read the file Sequentially
| for line in fin: |
-----------------------------------------------------------------------------------
grep 'something' | import re | The python version returns
| line = re.findall(r'something', line)[0] | a list of matches. We are only
| | interested in the zero group
-----------------------------------------------------------------------------------
cut -d'"' -f2 | line = line.split('"')[1] | Splits the string and selects

| | index 1 in python)
import re
with open("filename") as origin_file:
for line in origin_file:
line = re.findall(r'something', line)
if line:
line = line[0].split('"')[1]
print line
There is no :unchecked pseudo class however if you use the :checked pseudo class and the sibling selector you can differentiate between both states. I believe all of the latest browsers support the :checked pseudo class, you can find more info from this resource: http://www.whatstyle.net/articles/18/pretty_form_controls_with_css
Your going to get better browser support with jquery... you can use a click function to detect when the click happens and if its checked or not, then you can add a class or remove a class as necessary...
Here is a code improvement based on mcandal solution.
Added exception catching for any exception generated from the client.ConnectAsync
task (e.g: SocketException when server is unreachable)
var timeOut = TimeSpan.FromSeconds(5);
var cancellationCompletionSource = new TaskCompletionSource<bool>();
try
{
using (var cts = new CancellationTokenSource(timeOut))
{
using (var client = new TcpClient())
{
var task = client.ConnectAsync(hostUri, portNumber);
using (cts.Token.Register(() => cancellationCompletionSource.TrySetResult(true)))
{
if (task != await Task.WhenAny(task, cancellationCompletionSource.Task))
{
throw new OperationCanceledException(cts.Token);
}
// throw exception inside 'task' (if any)
if (task.Exception?.InnerException != null)
{
throw task.Exception.InnerException;
}
}
...
}
}
}
catch (OperationCanceledException operationCanceledEx)
{
// connection timeout
...
}
catch (SocketException socketEx)
{
...
}
catch (Exception ex)

}
You can use the core with GDB in many ways, but passing parameters which is to be passed to the executable to GDB is not the way to use the core file. This could also be the reason you got that error. You can use the core file in the following ways:
gdb <executable> <core-file>
or gdb <executable> -c <core-file>
or
gdb <executable>
...
(gdb) core <core-file>
When using the core file you don't have to pass arguments. The crash scenario is shown in GDB (checked with GDB version 7.1 on Ubuntu).
For example:
$ ./crash -p param1 -o param2
Segmentation fault (core dumped)
$ gdb ./crash core
GNU gdb (GDB) 7.1-ubuntu
...
Core was generated by `./crash -p param1 -o param2'. <<<<< See this line shows crash scenario

If you want to pass parameters to the executable to be debugged in GDB, use --args

A simple solution to an element of not knowing values:

There are multiple packages available for formatting console text in Node.js. The most popular are:
CHALK:
const chalk = require('chalk');
console.log(chalk.red('Text in red'));
COLORS:
const colors = require('colors');
console.log('Text in red'.red);
CLI-COLOR:
const clc = require('cli-color');
console.log(clc.red('Text in red'));
Many people have noted their disapproval of colors
altering the String prototype. If you prefer your prototypes to be left alone, use the following code instead:
const colors = require('colors/safe');
console.log(colors.red('Text in red'));
All you need is to Stop the ASP.NET Development Server and run the project again

Latest Git:
git merge --abort
This attempts to reset your working copy to whatever state it was in before the merge. That means that it should restore any uncommitted changes from before the merge, although it cannot always do so reliably. Generally you shouldn't merge with uncommitted changes anyway.
Prior to version 1.7.4:
git reset --merge
This is older syntax but does the same as the above.
Prior to version 1.6.2:
git reset --hard
which removes all uncommitted changes, including the uncommitted merge. Sometimes this behaviour is useful even in newer versions of Git that support the above commands.
To get the number of threads for a given pid:
$ ps -o nlwp <pid>
Where nlwp
stands for Number of Light Weight Processes (threads). Thus ps
aliases nlwp
to thcount
, which means that
$ ps -o thcount <pid>
does also work.
If you want to monitor the thread count, simply use watch
:
$ watch ps -o thcount <pid>
To get the sum of all threads running in the system:
$ ps -eo nlwp | tail -n +2 | awk '{ num_threads += $1 } END { print num_threads }'

You have 9 fields listed, but only 8 values. Try adding the method.
Here's my solution (requires no jQuery... just JavaScript):
function argsToArray(args) {
var r = []; for (var i = 0; i < args.length; i++)
r.push(args[i]);
return r;
}
function bind() {
var initArgs = argsToArray(arguments);
var fx = initArgs.shift();
var tObj = initArgs.shift();
var args = initArgs;
return function() {
return fx.apply(tObj, args.concat(argsToArray(arguments)));
};
}
var salutation = argsToArray(document.getElementsByClassName('salutation'));
salutation.forEach(function(checkbox) {
checkbox.addEventListener('change', bind(function(checkbox, salutation) {
var numChecked = salutation.filter(function(checkbox) { return checkbox.checked; }).length;
if (numChecked >= 4)
checkbox.checked = false;
}, null, checkbox, salutation), false);
});
Put this in a script block at the end of <body>
and the snippet will do its magic, limiting the number of checkboxes checked in maximum to three (or whatever number you specify).
Here, I'll even give you a test page (paste it into a file and try it):
<!DOCTYPE html><html><body>

function argsToArray(args) {
var r = []; for (var i = 0; i < args.length; i++)
r.push(args[i]);
return r;
}
function bind() {
var initArgs = argsToArray(arguments);
var fx = initArgs.shift();
var tObj = initArgs.shift();
var args = initArgs;
return function() {
return fx.apply(tObj, args.concat(argsToArray(arguments)));
};
}
var salutation = argsToArray(document.getElementsByClassName('salutation'));
salutation.forEach(function(checkbox) {
checkbox.addEventListener('change', bind(function(checkbox, salutation) {
var numChecked = salutation.filter(function(checkbox) { return checkbox.checked; }).length;
if (numChecked >= 3)
checkbox.checked = false;
}, null, checkbox, salutation), false);
});
</script></body></html>
Setting session timeout through the deployment descriptor should work - it sets the default session timeout for the web app. Calling session.setMaxInactiveInterval() sets the timeout for the particular session it is called on, and overrides the default. Be aware of the unit difference, too - the deployment descriptor version uses minutes, and session.setMaxInactiveInterval() uses seconds.
So
<session-config>
<session-timeout>60</session-timeout>
</session-config>
sets the default session timeout to 60 minutes.
And
session.setMaxInactiveInterval(600);
sets the session timeout to 600 seconds - 10 minutes - for the specific session it's called on.
This should work in Tomcat or Glassfish or any other Java web server - it's part of the spec.
You can use javascript's indexOf function.
var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
alert(str2 + " found");
}
To multiply, use mult
for signed multiplication and multu
for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0
that means that you assume the result will fit in 32 bits.
The 32 most significant bits will be held in the HI
special register (accessible by mfhi
instruction) and the 32 least significant bits will be held in the LO
special register (accessible by the mflo
instruction):
E.g.:
li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0
To divide, use div
for signed division and divu
for unsigned division. In this case, the HI
special register will hold the remainder and the LO
special register will hold the quotient of the division.
E.g.:
div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0
cp dir1/* dir2
Or if you have directories inside dir1 that you'd want to copy as well
cp -r dir1/* dir2
And escape your values with mysql_real_escape_string since PHP6 won't do that for you anymore! :)

I have faced the same problem once:
Pattern ptr = Pattern.compile("^[a-zA-Z][\\']?[a-zA-Z\\s]+$");
The above failed!
Pattern ptr = Pattern.compile("(^[a-zA-Z][\\']?[a-zA-Z\\s]+$)");
The above worked with pattern within (
and )
.
I also struggled with this and found no way to tell hive to skip first row, like there is e.g. in Greenplum. So finally I had to remove it from the files. e.g. "cat File.csv | grep -v RecordId > File_no_header.csv"
I think it is enough:
list.Select(s => s.MyField).Distinct();
In short: No.
There is a hack, use vector as underlaid container, so queue::front
will return valid reference, convert it to pointer an iterate until <= queue::back
Simplest is use list[i:i]
a = [1,2, 3, 4]
a[2:2] = [10]
Print a to check insertion
print a
[1, 2, 10, 3, 4]
You can also use
top.iframeName.print();
or
parent.iframeName.print();
As others have pointed out, this is very probably a problem with the path of the function file not being in Matlab's 'path'.
One easy way to verify this is to open your function in the Editor and press the F5 key. This would make the Editor try to run the file, and in case the file is not in path, it will prompt you with a message box. Choose Add to Path
in that, and you must be fine to go.
One side note: at the end of the above process, Matlab command window will give an error saying arguments missing: obviously, we didn't provide any arguments when we tried to run from the editor. But from now on you can use the function from the command line giving the correct arguments.
From my understanding, size_t
is an unsigned
integer whose bit size is large enough to hold a pointer of the native architecture.
So:
sizeof(size_t) >= sizeof(void*)
You can use as below:
string selected = cmbbox.Text;
MessageBox.Show(selected);
You have a type-o:
its: height: 200x;
and it should be: height: 200px;
also check the image url; it should be in the same directory it seems.
Also, dont use 'px' at null (aka '0') values. 0px, 0em, 0% is still 0. :)
top: 0px;
is the same with:
top: 0;
Good Luck!
You can also add underscore.js to your project and will be able to do it in one line:
_.map($("input[name='category_ids[]']:checked"), function(el){return $(el).val()})
It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.
Are you doing heavy DOM manipulation? I would use jQuery and Backbone.
Very data driven app? Angular with its nice data binding.
Game programming? None - direct to canvas; maybe a game engine.
Sorry for late reply. You can only use:
nav a:hover{
background-color:color name !important;
}
The other answers here have demonstrated how to define structs inside of classes. There’s another way to do this, and that’s to declare the struct inside the class, but define it outside. This can be useful, for example, if the struct is decently complex and likely to be used standalone in a way that would benefit from being described in detail somewhere else.
The syntax for this is as follows:
class Container {
...
struct Inner; // Declare, but not define, the struct.
...
};
struct Container::Inner {
/* Define the struct here. */
};
You more commonly would see this in the context of defining nested classes rather than structs (a common example would be defining an iterator type for a collection class), but I thought for completeness it would be worth showing off here.
Just to clarify, this '.class' method is not referring to the bytecode file you see after compiling java code nor a confusion between the concepts of Class vs. Object in OOP theory.
This '.class' method is used in Java for code Reflection. Generally you can gather meta data for your class such as the full qualified class name, list of constants, list of public fields, etc, etc.
Check these links (already mentioned above) to get all the details:
https://docs.oracle.com/javase/tutorial/reflect/class/classNew.html
https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html
Normally you don't plan on using Reflection right away when you start building your project. It's something that you know you need after trying to manage already working code. Many times you need it to manage multiple instances of your program. Maybe you want to identify each particular 'clone' to determine if something is already defined, or count the number of functions, or just simply log the details of a particular instance of your class.
While working with selected cells as shown by @tbur can be useful, it's also not the only option available.
You can use Range() like so:
If Worksheets("Sheet1").Range("A1").MergeCells Then
Do something
Else
Do something else
End If
Or:
If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
Do something
Else
Do something else
End If
Alternately, you can use Cells():
If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
Do something
Else
Do something else
End If
I hope this example helps. You ca use the curly braces to make sure you've got everything enclosed in the switcher changer guy (sorry don't know the technical term but the term that precedes the = sign that changes what happens). I think of switch as a more controlled bunch of if () {} else {}
statements.
Each time the switch function is the same but the command we supply changes.
do.this <- "T1"
switch(do.this,
T1={X <- t(mtcars)
colSums(mtcars)%*%X
},
T2={X <- colMeans(mtcars)
outer(X, X)
},
stop("Enter something that switches me!")
)
#########################################################
do.this <- "T2"
switch(do.this,
T1={X <- t(mtcars)
colSums(mtcars)%*%X
},
T2={X <- colMeans(mtcars)
outer(X, X)
},
stop("Enter something that switches me!")
)
########################################################
do.this <- "T3"
switch(do.this,
T1={X <- t(mtcars)
colSums(mtcars)%*%X
},
T2={X <- colMeans(mtcars)
outer(X, X)
},
stop("Enter something that switches me!")
)
Here it is inside a function:
FUN <- function(df, do.this){
switch(do.this,
T1={X <- t(df)
P <- colSums(df)%*%X
},
T2={X <- colMeans(df)
P <- outer(X, X)
},
stop("Enter something that switches me!")
)
return(P)
}
FUN(mtcars, "T1")
FUN(mtcars, "T2")
FUN(mtcars, "T3")
As long as you override equals()
on each key and value contained in the map, then m1.equals(m2)
should be reliable to check for maps equality.
The same result can be obtained also by comparing toString()
of each map as you suggested, but using equals()
is a more intuitive approach.
May not be your specific situation, but if you store arrays in the map, may be a little tricky, because they must be compared value by value, or using Arrays.equals()
. More details about this see here.

It does that because input.nextInt();
doesn't capture the newline. you could do like the others proposed by adding an input.nextLine();
underneath.
Alternatively you can do it C# style and parse a nextLine to an integer like so:
int number = Integer.parseInt(input.nextLine());
Doing this works just as well, and it saves you a line of code.

<wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
If you want to select every element that has class attribute "myclass" use
$('#mydiv .myclass');
If you want to select only div elements that has class attribute "myclass" use
$("div#mydiv div.myclass");

If post data is malformed, $_POST will not contain anything. Yet, php://input will have the malformed string.
For example there is some ajax applications, that do not form correct post key-value sequence for uploading a file, and just dump all the file as post data, without variable names or anything. $_POST will be empty, $_FILES empty also, and php://input will contain exact file, written as a string.
Python's eager in its evaluation, so eval(input(...))
(Python 3) will evaluate the user's input as soon as it hits the eval
, regardless of what you do with the data afterwards. Therefore, this is not safe, especially when you eval
user input.
Use ast.literal_eval
.
As an example, entering this at the prompt could be very bad for you:

when running Match. This seemed to generate signing certificates that were backwards-compatible with Xcode 11.3

No one is talking about Linux but all above answers will work. Just use Ctrl to select more than one file. If you are looking to compare side by side, Meld is lovely.
if in multiple class you want to change additional operation in perticular class that show in below example
$('.like').click(function(){
var like= $(this).text();
$(this).text(+like + +1);
});
A slight improvement using column name, IMHO:
Private Sub GridView1_Init(sender As Object, e As System.EventArgs) Handles GridView1.Init
For Each dcf As DataControlField In GridView1.Columns
Select Case dcf.HeaderText.ToUpper
Case "CBSELECT"
dcf.Visible = Me.CheckBoxVisible
dcf.HeaderText = "<small>Select</small>"
End Select
Next
End Sub
This allows control over multiple column. I initially use a 'technical' column name, matching the control name within. This makes it obvious within the ASCX page that it's a control column. Then swap out the name as desired for presentation. If I spy the odd name in production, I know I skipped something. The "ToUpper" avoids case-issues.
Finally, this runs ONE time on any post instead of capturing the event during row-creation.
This runs fine on Java 1.6

mozilla::CheckedInt<T>
provides overflow-checked integer math for integer type T
(using compiler intrinsics on clang and gcc as available). The code is under MPL 2.0 and depends on three (IntegerTypeTraits.h
, Attributes.h
and Compiler.h
) other header-only non-standard library headers plus Mozilla-specific assertion machinery. You probably want to replace the assertion machinery if you import the code.
Please put this code in head section
<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>
and use font-family: 'Lato', sans-serif;
in your css. For example:
h1 {
font-family: 'Lato', sans-serif;
font-weight: 400;
}
Or you can use manually also
Generate .ttf
font from fontSquiral
and can try this option
@font-face {
font-family: "Lato";
src: url('698242188-Lato-Bla.eot');
src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
url('698242188-Lato-Bla.woff') format('woff'),
url('698242188-Lato-Bla.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
Called like this
body {
font-family: 'Lato', sans-serif;
}
A very simple check you can do with Cell formulas:
Sheet 1 (new - old)
=(if(AND(Ref_New<>"";Ref_Old="");Ref_New;"")
Sheet 2 (old - new)
=(if(AND(Ref_Old<>"";Ref_New="");Ref_Old;"")
This formulas should work for an ENGLISH Excel. For other languages they need to be translated. (For German i can assist)
You need to open all three Excel Documents, then copy the first formula into A1 of your sheet 1 and the second into A1 of sheet 2. Now click in A1 of the first cell and mark "Ref_New", now you can select your reference, go to the new file and click in the A1, go back to sheet1 and do the same for "Ref_Old" with the old file. Replace also the other "Ref_New".
Doe the same for Sheet two.
Now copy the formaula form A1 over the complete range where zour data is in the old and the new file.
But two cases are not covered here:
To cover this two cases also, you should create your own function, means learn VBA. A very useful Excel page is cpearson.com
You don't need to go level up and use ..
since all buttons are on the same level:
//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']
For use in Kotlin inside fragment, which is a common use case it is very easy with KeyboardVisibilityEvent
library.
In build.gradle:
implementation 'net.yslibrary.keyboardvisibilityevent:keyboardvisibilityevent:3.0.0-RC2'
In Fragment:
activity?.let {
KeyboardVisibilityEvent.setEventListener(it,object: KeyboardVisibilityEventListener {
override fun onVisibilityChanged(isOpen: Boolean) {
if (isOpen) Toast.makeText(context,"Keyboard is opened",Toast.LENGTH_SHORT).show()
else Toast.makeText(context,"Keyboard is closed",Toast.LENGTH_SHORT).show()
}
})
}
A background worker is a class that works in a separate thread, but it provides additional functionality that you don't get with a simple Thread (like task progress report handling).
If you don't need the additional features given by a background worker - and it seems you don't - then a Thread would be more appropriate.
This worked for me
let exampleArray = [1, 2, 3, 4, 5];
let exampleToString = exampleArray.toString(); //convert to toString
let query = `Select * from table_name where column_name in (${exampleToString})`; //Execute the query to get response
I have got the same problem, then after an hour of effort I got to know that the array should not be directly accessed in the query. So I then found that the data should be sent in the paranthesis it self, then again I have converted that array to string using toString method in js. So I have worked by executing the above query and got my expected result
You need to convert the string to date using the to_date()
function
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31-Dec-2014','DD-MON-YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014','DD MON YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('2014-12-31','yyyy-MM-dd');
This will work only if OrderDate
is stored in Date format
. If it is Varchar
you should apply to_date()
func on that column also like
SELECT * FROM OrderArchive
WHERE to_date(OrderDate,'yyyy-Mm-dd') <= to_date('2014-12-31','yyyy-MM-dd');
Unicode Property Escapes are among the features of ES2018.
With Unicode Property Escapes, you can match a letter from any language with the following simple regular expression:
/\p{Letter}/u
Or with the shorthand, even terser:
/\p{L}/u
Regarding the question's concrete use case (matching words), note that you can use Unicode Property Escapes in character classes, making it easy to match letters together with other word-characters like hyphens:
/[\p{L}-]/u
Stitching it all together, you could match words of all[1] languages with this beautifully short RegEx:
/[\p{L}-]+/ug
Example (shamelessly plugged from the answer above):
'Düsseldorf, Köln, ??????, ???, ??????? !@#$'.match(/[\p{L}-]+/ug)
// ["Düsseldorf", "Köln", "??????", "???", "???????"]
[1] Note that I'm not an expert on languages. You may still want to do your own research regarding other characters that might be parts of words besides letters and hyphens.
This feature is available in all major evergreen browsers.
If support for older browsers is needed, Unicode Property Escapes can be transpiled to ES5 with a tool called regexpu. There's an online demo available here. As you can see in the demo, you can in fact match non-latin letters today with the following (horribly long) ES5 regular expression:

There is an option IdentityFile
which you can use in your ~/.ssh/config
file and specify key file for each host.
Host host_with_key1.net
IdentityFile ~/.ssh/id_rsa
Host host_with_key2.net
IdentityFile ~/.ssh/id_rsa_test

Nathan Lee's answer is perfect. I just wanted to add something about position:absolute;
. If you wanted to use position:absolute;
like you had in your code, you have to think of it as pushing it away from one side of the page.
For example, if you wanted your div
to be somewhere in the bottom, you would have to use position:absolute; top:500px;
. That would push your div
500px from the top of the page. Same rule applies for all other directions.
That's exactly what cursor: pointer;
is supposed to do.
If you want the cursor to remain normal, you should be using cursor: default

Existing answers point out that curl can post data from a file, and employ heredocs to avoid excessive quote escaping and clearly break the JSON out onto new lines. However there is no need to define a function or capture output from cat, because curl can post data from standard input. I find this form very readable:
curl -X POST -H 'Content-Type:application/json' --data '$@-' ${API_URL} << EOF

I solved my problem of reading portuguese characters, changing the source file on notepad++.
C#
var url = System.Web.HttpContext.Current.Server.MapPath(@"~/Content/data.json");
string s = string.Empty;
using (System.IO.StreamReader sr = new System.IO.StreamReader(url, System.Text.Encoding.UTF8,true))
{
s = sr.ReadToEnd();
}
You could run the Dotnet CLI with full diagnostic verbosity to help find the issue.
dotnet run --verbosity diagnostic >> full_build.log
Once the build is complete you can search through the log file (full_build.log) for the error. Searching for "a conflict" for example, should take you right to the problem.

I finally solved this by creating a second object that imitates B.
My schema now looks like this:
I now have B1 (within parent of A) and B2 outside of it.
B1 and B2 are right next to one another, so to the naked eye it looks as if it's just 1 object.

I've not had much luck with \r\n regular expressions from the find/replace window.
However, this works in Notepad++ v4.1.2:
Use the "View | Show end of line" menu to enable display of end of line characters. (Carriage return line feeds should show up as a single shaded CRLF 'character'.)
Select one of the CRLF 'characters' (put the cursor just in front of one, hold down the SHIFT key, and then pressing the RIGHT CURSOR key once).
Copy the CRLF character to the clipboard.
Make sure that you don't have the find or find/replace dialog open.
Open the find/replace dialog. The 'Find what' field shows the contents of the clipboard: in this case the CRLF character - which shows up as 2 'box characters' (presumably it's an unprintable character?)
Ensure that the 'Regular expression' option is OFF.
Now you should be able to count, find, or replace as desired.
GET CURRENT UTC TIME IN REQUIRED FORMAT
// Current UTC time
OffsetDateTime utc = OffsetDateTime.now(ZoneOffset.UTC);

LocalDateTime localDateTime = utc.toLocalDateTime();
System.out.println("*************" + localDateTime);

DateTimeFormatter dTF = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
System.out.println(" formats as " + dTF.format(localDateTime));
//GET UTC time for current date
Date now= new Date();
LocalDateTime utcDateTimeForCurrentDateTime = Instant.ofEpochMilli(now.getTime()).atZone(ZoneId.of("UTC")).toLocalDateTime();
DateTimeFormatter dTF2 = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");

try Parsing and Formatting
Take an example Parsing
String input = ...;
try {
DateTimeFormatter formatter =
DateTimeFormatter.ofPattern("MMM d yyyy");
LocalDate date = LocalDate.parse(input, formatter);
System.out.printf("%s%n", date);
}
catch (DateTimeParseException exc) {
System.out.printf("%s is not parsable!%n", input);
throw exc; // Rethrow the exception.
}
Formatting
ZoneId leavingZone = ...;
ZonedDateTime departure = ...;
try {
DateTimeFormatter format = DateTimeFormatter.ofPattern("MMM d yyyy hh:mm a");
String out = departure.format(format);
System.out.printf("LEAVING: %s (%s)%n", out, leavingZone);
}
catch (DateTimeException exc) {
System.out.printf("%s can't be formatted!%n", departure);
throw exc;
}
The output for this example, which prints both the arrival and departure time, is as follows:
LEAVING: Jul 20 2013 07:30 PM (America/Los_Angeles)
ARRIVING: Jul 21 2013 10:20 PM (Asia/Tokyo)

dict.keys()
Keys and values are iterated over in an arbitrary order which is non-random, varies across Python implementations, and depends on the dictionary’s history of insertions and deletions. If keys, values and items views are iterated over with no intervening modifications to the dictionary, the order of items will directly correspond.
That's why you see the indices 0 to 7 in the first column. They are produced by enumerate
and are always in the correct order. Further you see the dict's keys 0 to 7 in the second column. They are not sorted.
Sun's JDK6:
I believe that it grows to 15 elements. Not coding it out, but looking at the grow() code in the jdk.
int newCapacity then = 10 + (10 >> 1) = 15.
/**
* Increases the capacity to ensure that it can hold at least the
* number of elements specified by the minimum capacity argument.
*
* @param minCapacity the desired minimum capacity
*/
private void grow(int minCapacity) {
// overflow-conscious code
int oldCapacity = elementData.length;
int newCapacity = oldCapacity + (oldCapacity >> 1);
if (newCapacity - minCapacity < 0)
newCapacity = minCapacity;
if (newCapacity - MAX_ARRAY_SIZE > 0)
newCapacity = hugeCapacity(minCapacity);
// minCapacity is usually close to size, so this is a win:
elementData = Arrays.copyOf(elementData, newCapacity);
}
From the Javadoc, it says this is from Java 2 and on, so its a safe bet in the Sun JDK.
EDIT : for those who didn't get what's the connection between multiplying factor 1.5
and int newCapacity = oldCapacity + (oldCapacity >> 1);
>>
is right shift operator which reduces a number to its half.
Thus,
int newCapacity = oldCapacity + (oldCapacity >> 1);
=> int newCapacity = oldCapacity + 0.5*oldCapacity;
=> int newCapacity = 1.5*oldCapacity ;
How about this simple solution? :)

Use the following code to rotate an image correctly:
private Bitmap rotateImage(Bitmap bitmap, String filePath)

ExifInterface exifInterface = new ExifInterface(filePath);
int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);

if (orientation == ExifInterface.ORIENTATION_ROTATE_90)
{
matrix.postRotate(ExifInterface.ORIENTATION_ROTATE_90);

else if (orientation == ExifInterface.ORIENTATION_ROTATE_180)
{
matrix.postRotate(ExifInterface.ORIENTATION_ROTATE_180);
}
else if (orientation == ExifInterface.ORIENTATION_ROTATE_270)
{
matrix.postRotate(ExifInterface.ORIENTATION_ROTATE_270);
}
// Rotate the bitmap
resultBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}
catch (Exception exception)
{
Logger.d("Could not rotate the image");
}
return resultBitmap;

I had Microsoft Access Database Engine 2010 Redistributable already installed on my machine but was still receiving the Microsoft ACE OLEDB Provider error.
Then I recalled that I had upgraded to Office 2016 recently, so, may be I should try reinstalling Microsoft Access Database Engine 2010 Redistributable. And that fixed the problem on my machine.
So, if you have upgraded to different version of MS Office or even repaired/reinstalled your MS Office then try reinstalling Microsoft Access Database Engine 2010 Redistributable before wasting time with finding other fixes. Good luck!
I think the problem is that you load
isfar
data.frame but you overwrite it by value returned by load
.
Try either:
load("C:/Users/isfar.RData")
head(isfar)
Or more general way
load("C:/Users/isfar.RData", ex <- new.env())
ls.str(ex)
You can also try this simple one-liner code. Just call the alert method on onclick attribute.

std::string
is the C++ equivalent: It's mutable.
Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.
If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like
double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);
(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)
string.Format
is your friend.
String.Format("{0:0.00}", 123.4567); // "123.46"
[Update: As of its 4.0 release, Express no longer uses Connect. However, Express is still compatible with middleware written for Connect. My original answer is below.]
I'm glad you asked about this, because it's definitely a common point of confusion for folks looking at Node.js. Here's my best shot at explaining it:
Node.js itself offers an http module, whose createServer
method returns an object that you can use to respond to HTTP requests. That object inherits the http.Server
prototype.
Connect also offers a createServer
method, which returns an object that inherits an extended version of http.Server
. Connect's extensions are mainly there to make it easy to plug in middleware. That's why Connect describes itself as a "middleware framework," and is often analogized to Ruby's Rack.
Express does to Connect what Connect does to the http module: It offers a createServer
method that extends Connect's Server
prototype. So all of the functionality of Connect is there, plus view rendering and a handy DSL for describing routes. Ruby's Sinatra is a good analogy.
Then there are other frameworks that go even further and extend Express! Zappa, for instance, which integrates support for CoffeeScript, server-side jQuery, and testing.
Here's a concrete example of what's meant by "middleware": Out of the box, none of the above serves static files for you. But just throw in connect.static
(a middleware that comes with Connect), configured to point to a directory, and your server will provide access to the files in that directory. Note that Express provides Connect's middlewares also; express.static
is the same as connect.static
. (Both were known as staticProvider
until recently.)
My impression is that most "real" Node.js apps are being developed with Express these days; the features it adds are extremely useful, and all of the lower-level functionality is still there if you want it.
I just got this error because I did not enclose all my form controls within a div

Monolithic kernel is a single large process running entirely in a single address space. It is a single static binary file. All kernel services exist and execute in the kernel address space. The kernel can invoke functions directly. Examples of monolithic kernel based OSs: Unix, Linux.
In microkernels, the kernel is broken down into separate processes, known as servers. Some of the servers run in kernel space and some run in user-space. All servers are kept separate and run in different address spaces. Servers invoke "services" from each other by sending messages via IPC (Interprocess Communication). This separation has the advantage that if one server fails, other servers can still work efficiently. Examples of microkernel based OSs: Mac OS X and Windows NT.
I got this error recently by introducing an old plugin to wordpress. It loaded an older version of jquery, which happened to be placed before the jquery mouse file. There was no jquery widget file loaded with the second version, which caused the error.
No error for using the extra jquery library -- that's a problem especially if a silent fail might have happened, causing a not so silent fail later on.
A potential way around it for wordpress might be to be explicit about the dependencies that way the jquery mouse would follow the widget which would follow the correct core leaving the other jquery to be loaded afterwards. Still might cause a production error later if you don't catch that and change the default function for jquery for the second version in all the files associated with it.
In Python 3.7 a new keyword argument capture_output

In my case, just using flex-shrink: 0
didn't work. But adding flex-grow: 1

So, this is a code snippet to help better understand this topic.
Printing Tokens
Task: Given a sentence, s, print each word of the sentence in a new line.
char *s;
s = malloc(1024 * sizeof(char));
scanf("%[^\n]", s);
s = realloc(s, strlen(s) + 1);
//logic to print the tokens of the sentence.
for (char *p = strtok(s," "); p != NULL; p = strtok(NULL, " "))
{
printf("%s\n",p);
}
Input: How is that
Result:
How
is
that
Explanation: So here, "strtok()" function is used and it's iterated using for loop to print the tokens in separate lines.
The function will take parameters as 'string' and 'break-point' and break the string at those break-points and form tokens. Now, those tokens are stored in 'p' and are used further for printing.
The usual way is to use zip()
:
for x, y in zip(a, b):
# x is from a, y is from b
This will stop when the shorter of the two iterables a
and b
is exhausted. Also worth noting: itertools.izip()
(Python 2 only) and itertools.izip_longest()
(itertools.zip_longest()
in Python 3).
To build upon Unknown's example, the Python equivalent of the function normdist() implemented in a lot of libraries would be:
def normcdf(x, mu, sigma):
t = x-mu;
y = 0.5*erfcc(-t/(sigma*sqrt(2.0)));
if y>1.0:
y = 1.0;
return y
def normpdf(x, mu, sigma):
u = (x-mu)/abs(sigma)
y = (1/(sqrt(2*pi)*abs(sigma)))*exp(-u*u/2)
return y
def normdist(x, mu, sigma, f):
if f:
y = normcdf(x,mu,sigma)
else:
y = normpdf(x,mu,sigma)
return y
If you return a serializable object, WebAPI will automatically send JSON or XML based on the Accept header that your client sends.
If you return a string, you'll get a string.
Do you have to use DataTable.Select()
? I prefer to write a linq query for this kind of thing.
var dValue= from row in myDataTable.AsEnumerable()
where row.Field<int>("A") == 1
&& row.Field<int>("B") == 2
&& row.Field<int>("C") == 3
select row.Field<string>("D");
In ng6 you need to use this command, according to a similar post:
ng config schematics.@schematics/angular:component '{ styleext: "scss"}'
Decoding is redundant
You only had this "error" in the first place, because of a misunderstanding of what's happening.
You get the b
because you encoded to utf-8
and now it's a bytes object.
>> type("text".encode("utf-8"))
>> <class 'bytes'>

Now you can put a watermark on any TextBox like this:
<AdornerDecorator>
<TextBox x:Name="SearchTextBox">
<controls:WatermarkService.Watermark>
<TextBlock>Type here to search text</TextBlock>
</controls:WatermarkService.Watermark>
</TextBox>
</AdornerDecorator>
The watermark can be anything you want (text, images ...). In addition to working for TextBoxes, this watermark also works for ComboBoxes and ItemControls.
This code was adapted from this blog post.
If your list of words is of substantial length, and you need to do this test many times, it may be worth converting the list to a set and using set intersection to test (with the added benefit that you wil get the actual words that are in both lists):
>>> long_word_list = 'some one long two phrase three about above along after against'
>>> long_word_set = set(long_word_list.split())
>>> set('word along river'.split()) & long_word_set
set(['along'])
Try this one:
Data objt = new Data(name, address, contact);
Contacts.add(objt);
In my case, where the timezones are not available on the server, this works great:
SELECT CONVERT_TZ(`date_field`,'+00:00',@@global.time_zone) FROM `table`
Note: global.time_zone uses the server timezone. You have to make sure, that it has the desired timezone!
I think this should work
destroyView : function () {
this.$el.remove();
}
Going off of what Surreal Dreams said, it's probably best to style the anchor tag in my experience, but it really does depend on what you are doing. Here's an example:
Html:
<div class="parent-div">
<a href="#">Test</a>
<a href="#">Test</a>
<a href="#">Test</a>
</div>
Then the CSS:
.parent-div {
width: 200px;
}
a {
display:block;
background-color: #ccc;
color: #000;
text-decoration:none;
padding:10px;
margin-bottom:1px;
}
a:hover {
background-color: #ddd;
}
You need to use HAVING
, not WHERE
.
The difference is: the WHERE
clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT
function.
HAVING
is like WHERE
, only it happens after the COUNT
value has been computed, so it'll work as you expect. Rewrite your subquery as:
( -- where that pid is in the set:
SELECT c2.pid -- of pids
FROM Catalog AS c2 -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)
I would like to show you the way I access IISExpress Web APIs from my Android Emulator. I'm using Visual Studio 2015. And I call the Android Emulator from Android Studio.
All of what I need to do is adding the following line to the binding configuration in my applicationhost.config file
<binding protocol="http" bindingInformation="*:<your-port>:" />
Then I check and use the IP4 Address to access my API from Android emulator
Requirement: you must run Visual Studio as Administrator. This post gives a perfect way to do this.

using (var Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true))
Key.SetValue(appName, 99999, RegistryValueKind.DWord);
According to what I read here (Controlling WebBrowser Control Compatibility:
What Happens if I Set the FEATURE_BROWSER_EMULATION Document Mode Value Higher than the IE Version on the Client?
Obviously, the browser control can only support a document mode that is less than or equal to the IE version installed on the client. Using the FEATURE_BROWSER_EMULATION key works best for enterprise line of business apps where there is a deployed and support version of the browser. In the case you set the value to a browser mode that is a higher version than the browser version installed on the client, the browser control will choose the highest document mode available.

"Performance and speed"? Aren't those kind of ... synonyms, here?
Anyway, the recv()
call takes flags that read()
doesn't, which makes it more powerful, or at least more convenient. That is one difference. I don't think there is a significant performance difference, but haven't tested for it.
You can follow the below step to modify the .war file name if you are using maven project.
Open pom.xml file of your maven project and go to the tag <build></build>
,
In that give your desired name between this tag :
<finalName></finalName>
.
ex. : <finalName>krutik</finalName>
After deploying this .war you will be able to access url with:
http://localhost:8080/krutik/
If you want to access the url with slash '/' then you will have to specify then name as below:
e.x. : <finalName>krutik#maheta</finalName>
After deploying this .war you will be able to access url with:
http://localhost:8080/krutik/maheta
You can add/remove Appender programmatically to Log4j:
ConsoleAppender console = new ConsoleAppender(); //create appender
//configure the appender
String PATTERN = "%d [%p|%c|%C{1}] %m%n";
console.setLayout(new PatternLayout(PATTERN));
console.setThreshold(Level.FATAL);
console.activateOptions();
//add appender to any Logger (here is root)
Logger.getRootLogger().addAppender(console);
FileAppender fa = new FileAppender();
fa.setName("FileLogger");
fa.setFile("mylog.log");
fa.setLayout(new PatternLayout("%d %-5p [%c{1}] %m%n"));
fa.setThreshold(Level.DEBUG);
fa.setAppend(true);
fa.activateOptions();
//add appender to any Logger (here is root)
Logger.getRootLogger().addAppender(fa);
//repeat with all other desired appenders
I'd suggest you put it into an init() somewhere, where you are sure, that this will be executed before anything else. You can then remove all existing appenders on the root logger with
Logger.getRootLogger().getLoggerRepository().resetConfiguration();
and start with adding your own. You need log4j in the classpath of course for this to work.
Remark:
You can take any Logger.getLogger(...)
you like to add appenders. I just took the root logger because it is at the bottom of all things and will handle everything that is passed through other appenders in other categories (unless configured otherwise by setting the additivity flag).
If you need to know how logging works and how is decided where logs are written read this manual for more infos about that.
In Short:
Logger fizz = LoggerFactory.getLogger("com.fizz")
will give you a logger for the category "com.fizz".
For the above example this means that everything logged with it will be referred to the console and file appender on the root logger.
If you add an appender to
Logger.getLogger("com.fizz").addAppender(newAppender)
then logging from fizz
will be handled by alle the appenders from the root logger and the newAppender
.
You don't create Loggers with the configuration, you just provide handlers for all possible categories in your system.
Change

Can you show code which you use for setting date object? Anyway< you can use this code for intialisation of date:
new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").parse("2011-01-01 00:00:00")
Have you tried loading the socket.io script not from a relative URL?
You're using:
<script src="socket.io/socket.io.js"></script>
And:
socket.connect('http://127.0.0.1:8080');
You should try:
<script src="http://localhost:8080/socket.io/socket.io.js"></script>
And:
socket.connect('http://localhost:8080');
Switch localhost:8080
with whatever fits your current setup.
Also, depending on your setup, you may have some issues communicating to the server when loading the client page from a different domain (same-origin policy). This can be overcome in different ways (outside of the scope of this answer, google/SO it).
As mentioned here, markdown do not support right aligned text or blocks. But the HTML result does it, via Cascading Style Sheets (CSS).
On my Jekyll Blog is use a syntax which works in markdown as well. To "terminate" a block use two spaces at the end or two times new line.
Of course you can also add a css-class with {: .right }
instead of {: style="text-align: right" }
.
Text to right
{: style="text-align: right" }
This text is on the right
Text as block
{: style="text-align: justify" }
This text is a block
ctypes can be used to access dlls, here's a tutorial:
I had the same issue, but I simply solved it by adding -lm after the command that runs my code. Example. gcc code.c -lm
In this code:
class Cat:
def __init__(self, name):
self.name = name
def info(self):
print 'I am a cat and I am called', self.name
Here __init__
acts as a constructor for the class and when an object is instantiated, this function is called. self
represents the instantiating object.
c = Cat('Kitty')
c.info()
The result of the above statements will be as follows:
I am a cat and I am called Kitty
// declarations.d.ts
export interface IMyTable {
id: number;
title: string;
createdAt: Date;
isDeleted: boolean
}
declare var Tes: IMyTable;
// call in annother page
console.log(Tes.id);
Try with this:
const { jasper } = this.state; //Gets the object from state
jasper.name = 'A new name'; //do whatever you want with the object
this.setState({jasper}); //Replace the object in state
If you want to open Form2
modally (meaning you can't click on Form1 while Form2 is open), you can do this:
using (Form2 f2 = new Form2())
{
f2.ShowDialog(this);
}
If you want to open Form2 non-modally (meaning you can still click on Form1 while Form2 is open), you can create a form-level reference to Form2 like this:
private Form2 _f2;
public void openForm2()
{
_f2 = new Form2();
_f2.Show(this); // the "this" is important, as this will keep Form2 open above
// Form1.
}
public void closeForm2()
{
_f2.Close();
_f2.Dispose();
}
Open .sln in a text editor, and in the following line change <FolderName> to your new folder name Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "Ricky", "\.csproj", "{021CC6B0-8CFB-4194-A103-C19AF869D965}"
For others facing a similar problem to mine, where you know a particular object property cannot be null, you can use the non-null assertion operator (!) after the item in question. This was my code:
const naciStatus = dataToSend.naci?.statusNACI;
if (typeof naciStatus != "undefined") {
switch (naciStatus) {
case "AP":
dataToSend.naci.certificateStatus = "FALSE";
break;
case "AS":
case "WR":
dataToSend.naci.certificateStatus = "TRUE";
break;
default:
dataToSend.naci.certificateStatus = "";
}
}
And because dataToSend.naci
cannot be undefined in the switch statement, the code can be updated to include exclamation marks as follows:
const naciStatus = dataToSend.naci?.statusNACI;
if (typeof naciStatus != "undefined") {
switch (naciStatus) {
case "AP":
dataToSend.naci!.certificateStatus = "FALSE";
break;
case "AS":
case "WR":
dataToSend.naci!.certificateStatus = "TRUE";
break;
default:
dataToSend.naci!.certificateStatus = "";
}
}
Here is the HTML for image upload. By default it will show image files only in the browsing window because we have put accept="image/*"
. But we can still change it from the dropdown and it will show all files. So the Javascript part validates whether or not the selected file is an actual image.
<div class="col-sm-8 img-upload-section">
<input name="image3" type="file" accept="image/*" id="menu_images"/>
<img id="menu_image" class="preview_img" />
<input type="submit" value="Submit" />
</div>
Here on the change event we first check the size of the image. And in the second if
condition we check whether or not it is an image file.
this.files[0].type.indexOf("image")
will be -1
if it is not an image file.
document.getElementById("menu_images").onchange = function () {
var reader = new FileReader();
if(this.files[0].size>528385){
alert("Image Size should not be greater than 500Kb");
$("#menu_image").attr("src","blank");
$("#menu_image").hide();
$('#menu_images').wrap('<form>').closest('form').get(0).reset();
$('#menu_images').unwrap();
return false;
}
if(this.files[0].type.indexOf("image")==-1){
alert("Invalid Type");
$("#menu_image").attr("src","blank");
$("#menu_image").hide();
$('#menu_images').wrap('<form>').closest('form').get(0).reset();
$('#menu_images').unwrap();
return false;
}
reader.onload = function (e) {
// get loaded data and render thumbnail.
document.getElementById("menu_image").src = e.target.result;
$("#menu_image").show();
};
// read the image file as a data URL.
reader.readAsDataURL(this.files[0]);
};
Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time
#!/bin/bash
path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)
filename=log_$timestamp.txt
log=$path$filename
days=7
START_TIME=$(date +%s)
find $path -maxdepth 1 -name "*.txt" -type f -mtime +$days -print -delete >> $log
echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log
... code for backup ...or any other operation .... >> $log
END_TIME=$(date +%s)
ELAPSED_TIME=$(( $END_TIME - $START_TIME ))
echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time :: $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) " >> $log
The code adds a few things.
Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.
Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'
Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days
-mtime +$days ---> -mmin +$((60*24*$days))
Firstly create a new class that extends the WorldView
class. I called my new class Background
. So in this new class import all the Java packages you will need in order to override the paintBackground
method. This should be:
import city.soi.platform.*;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.image.ImageObserver;
import javax.swing.ImageIcon;
import java.awt.geom.AffineTransform;
Next after the class name make sure that it says extends WorldView
. Something like this:
public class Background extends WorldView
Then declare the variables game of type Game
and an image variable of type Image
something like this:
private Game game;
private Image image;
Then in the constructor of this class make sure the game of type Game
is in the signature of the constructor and that in the call to super
you will have to initialise the WorldView
, initialise the game and initialise the image variables, something like this:
super(game.getCurrentLevel().getWorld(), game.getWidth(), game.getHeight());
this.game = game;
bg = (new ImageIcon("lol.png")).getImage();
Then you just override the paintBackground
method in exactly the same way as you did when overriding the paint
method in the Player
class. Just like this:
public void paintBackground(Graphics2D g)
{
float x = getX();
float y = getY();
AffineTransform transform = AffineTransform.getTranslateInstance(x,y);
g.drawImage(bg, transform, game.getView());
}
Now finally you have to declare a class level reference to the new class you just made in the Game
class and initialise this in the Game
constructor, something like this:
private Background image;
And in the Game constructor:
image = new Background(this);
Lastly all you have to do is add the background to the frame! That's the thing I'm sure we were all missing. To do that you have to do something like this after the variable frame
has been declared:
frame.add(image);
Make sure you add this code just before frame.pack();
.
Also make sure you use a background image that isn't too big!
Now that's it! Ive noticed that the game engines can handle JPEG and PNG image formats but could also support others. Even though this helps include a background image in your game, it is not perfect! Because once you go to the next level all your platforms and sprites are invisible and all you can see is your background image and any JLabels/Jbuttons you have included in the game.
There are three scenarios (that I can think of) where you would call a method in a subclass where the method exits in the parent class:
Method is not overwritten by subclass, only exists in parent.
This is the same as your example, and generally it's better to use $this -> get_species();
You are right that in this case the two are effectively the same, but the method has been inherited by the subclass, so there is no reason to differentiate. By using $this
you stay consistent between inherited methods and locally declared methods.
Method is overwritten by the subclass and has totally unique logic from the parent.
In this case, you would obviously want to use $this -> get_species();
because you don't want the parent's version of the method executed. Again, by consistently using $this
, you don't need to worry about the distinction between this case and the first.
Method extends parent class, adding on to what the parent method achieves.
In this case, you still want to use `$this -> get_species();
when calling the method from other methods of the subclass. The one place you will call the parent method would be from the method that is overwriting the parent method. Example:
abstract class Animal {
function get_species() {
echo "I am an animal.";
}
}
class Dog extends Animal {
function __construct(){
$this->get_species();
}
function get_species(){
parent::get_species();
echo "More specifically, I am a dog.";
}
}
The only scenario I can imagine where you would need to call the parent method directly outside of the overriding method would be if they did two different things and you knew you needed the parent's version of the method, not the local. This shouldn't be the case, but if it did present itself, the clean way to approach this would be to create a new method with a name like get_parentSpecies()
where all it does is call the parent method:
function get_parentSpecies(){
parent::get_species();
}
Again, this keeps everything nice and consistent, allowing for changes/modifications to the local method rather than relying on the parent method.
Here a solution that will work with Solaris and AIX as well.
Manipulating the Timezone is possible for changing the clock some hours. Due to the daylight saving time, 24 hours ago can be today or the day before yesterday.
You are sure that yesterday is 20 or 30 hours ago. Which one? Well, the most recent one that is not today.
echo -e "$(TZ=GMT+30 date +%Y-%m-%d)\n$(TZ=GMT+20 date +%Y-%m-%d)" | grep -v $(date +%Y-%m-%d) | tail -1
The -e parameter used in the echo command is needed with bash, but will not work with ksh. In ksh you can use the same command without the -e flag.
When your script will be used in different environments, you can start the script with #!/bin/ksh or #!/bin/bash. You could also replace the \n by a newline:
echo "$(TZ=GMT+30 date +%Y-%m-%d)
$(TZ=GMT+20 date +%Y-%m-%d)" | grep -v $(date +%Y-%m-%d) | tail -1
Global variables are exactly like global stars (Jackie Chan, Nelson Mandela). You can access them (get or set the value), from any part of your application. Global functions are like global events (New Year, Christmas). You can execute (call) them from any part of your application.
//global variable
var a = 2;
//global function
function b(){
console.log(a); //access global variable
}
If you are in the USA, you may know Kim Kardashian, infamous celebrity ( she somehow manages to make the tabloids). But people outside of the USA will not recognize her. She is a local star, bound to her territory.
Local variables are like local stars. You can only access them (get or set the value) inside the scope. A local function is like local events - you can execute only (celebrate) inside that scope. If you want to access them from outside of the scope, you will get a reference error
function b(){
var d = 21; //local variable
console.log(d);
function dog(){ console.log(a); }
dog(); //execute local function
}
console.log(d); //ReferenceError: dddddd is not defined
