is part of the ruby1.9.1-dev
package. This package contains the header files needed for extension libraries for Ruby 1.9.1. You need to install the ruby1.9.1-dev
package by doing:
sudo apt-get install ruby1.9.1-dev
Then you can install Rails as per normal.
Generally it's easier to just do:
sudo apt-get install ruby-dev
Since you didn't specify what server-side scripting method you're using, I'll give you an example that works for Python, using CherryPy (although it may be useful for other contexts, too):
<button type="submit" name="register">Create a new account</button>
<button type="submit" name="login">Log into your account</button>
Rather than using the value to determine which button was pressed, you can use the name (with the <button>
tag instead of <input>
). That way, if your buttons happen to have the same text, it won't cause problems. The names of all form items, including buttons, are sent as part of the URL. In CherryPy, each of those is an argument for a method that does the server-side code. So, if your method just has **kwargs
for its parameter list (instead of tediously typing out every single name of each form item) then you can check to see which button was pressed like this:
if "register" in kwargs:
pass #Do the register code
elif "login" in kwargs:
pass #Do the login code
I use the && expression which works perfectly for me.
For example,
<button ng-model="vm.slideOneValid" ng-disabled="!vm.slideOneValid" ng-click="vm.slideOneValid && vm.nextSlide()" class="btn btn-light-green btn-medium pull-right">Next</button>
If vm.slideOneValid
is false, the second part of the expression is not fired. I know this is putting logic into the DOM, but it's a quick a dirty way to get ng-disabled and ng-click to place nice.
Just remember to add ng-model to the element to make ng-disabled work.
You don't need the jsp:useBean
to set the model if you already have a controller which prepared the model.
Just access it plain by EL:
<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>
or by JSTL <c:out>
tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:
<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>
Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.
session.setAttribute("questions", questions);
and alter EL accordingly to use ${questions}
.
Also note that you don't have any JSTL tag in your code. It's all plain JSP.
In my case, I was having a similar problem:
/usr/bin/ld: Bank.cpp:(.text+0x19c): undefined reference to 'Account::SetBank(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)' collect2: error: ld returned 1 exit status
After some researches, I realized that the problem was being generated by the way that Visual Studio Code was compiling the Bank.cpp file. So, to solve that, I just prompted the follow command in order to compile the c++ file sucessful:
g++ Bank.cpp Account.cpp -o Bank
With the command above, It was able to linkage correctly the Header, Implementations and Main c++ files.
OBS: My g++ version: 9.3.0 on Ubuntu 20.04
How to add new line in Markdown presentation?
Check the following resource Line Return
To force a line return, place two empty spaces at the end of a line.
For example 1 and 2 you need to create static methods:
public static string InstanceMethod() {return "Hello World";}
Then for example 3 you need an instance of your object to invoke the method:
object o = new object();
string s = o.InstanceMethod();
Most commonly, you'd use:
import random
random.uniform(a, b) # range [a, b) or [a, b] depending on floating-point rounding
Python provides other distributions if you need.
If you have numpy
imported already, you can used its equivalent:
import numpy as np
np.random.uniform(a, b) # range [a, b)
Again, if you need another distribution, numpy
provides the same distributions as python, as well as many additional ones.

I have worked alot with msaccess vba. I think you are looking for MID function
example
dim myReturn as string
myreturn = mid("bonjour tout le monde",9,4)
will give you back the value "tout"
Maybe you need "sys." before:
select * from sys.registry$history;
Rostyslav Dzinko's answer is very appropriate. I thought I could highlight one other reason you should choose @classmethod
over @staticmethod
when you are creating an additional constructor.
In the example above, Rostyslav used the @classmethod
from_string
as a Factory to create Date
objects from otherwise unacceptable parameters. The same can be done with @staticmethod
as is shown in the code below:
class Date:
def __init__(self, month, day, year):
self.month = month
self.day = day
self.year = year
def display(self):
return "{0}-{1}-{2}".format(self.month, self.day, self.year)
@staticmethod
def millenium(month, day):
return Date(month, day, 2000)
new_year = Date(1, 1, 2013) # Creates a new Date object
millenium_new_year = Date.millenium(1, 1) # also creates a Date object.
# Proof:
new_year.display() # "1-1-2013"
millenium_new_year.display() # "1-1-2000"
isinstance(new_year, Date) # True
isinstance(millenium_new_year, Date) # True
Thus both new_year
and millenium_new_year
are instances of the Date
class.
But, if you observe closely, the Factory process is hard-coded to create Date
objects no matter what. What this means is that even if the Date
class is subclassed, the subclasses will still create plain Date
objects (without any properties of the subclass). See that in the example below:
class DateTime(Date):
def display(self):
return "{0}-{1}-{2} - 00:00:00PM".format(self.month, self.day, self.year)
datetime1 = DateTime(10, 10, 1990)
datetime2 = DateTime.millenium(10, 10)
isinstance(datetime1, DateTime) # True
isinstance(datetime2, DateTime) # False
datetime1.display() # returns "10-10-1990 - 00:00:00PM"
datetime2.display() # returns "10-10-2000" because it's not a DateTime object but a Date object. Check the implementation of the millenium method on the Date class for more details.
datetime2
is not an instance of DateTime
? WTF? Well, that's because of the @staticmethod
decorator used.
In most cases, this is undesired. If what you want is a Factory method that is aware of the class that called it, then @classmethod
is what you need.
Rewriting Date.millenium
as (that's the only part of the above code that changes):
@classmethod
def millenium(cls, month, day):
return cls(month, day, 2000)
ensures that the class
is not hard-coded but rather learnt. cls
can be any subclass. The resulting object
will rightly be an instance of cls
.
Let's test that out:
datetime1 = DateTime(10, 10, 1990)
datetime2 = DateTime.millenium(10, 10)
isinstance(datetime1, DateTime) # True
isinstance(datetime2, DateTime) # True
datetime1.display() # "10-10-1990 - 00:00:00PM"
datetime2.display() # "10-10-2000 - 00:00:00PM"
The reason is, as you know by now, that @classmethod
was used instead of @staticmethod
if you have the file inside a dirrectory called uploads in your project. bellow code can be used.
Path root = Paths.get("uploads");
File existingFile = new File(this.root.resolve("img.png").toUri());
if (existingFile.exists() && existingFile.isFile()) {
existingFile.delete();
}
OR
If it is inside a different directory this solution can be used.
File existingFile = new File("D:\\<path>\\img.png");
if (existingFile.exists() && existingFile.isFile()) {
existingFile.delete();
}
You can retrieve the format strings from the CultureInfo
DateTimeFormat
property, which is a DateTimeFormatInfo
instance. This in turn has properties like ShortDatePattern
and ShortTimePattern
, containing the format strings:
CultureInfo us = new CultureInfo("en-US");
string shortUsDateFormatString = us.DateTimeFormat.ShortDatePattern;
string shortUsTimeFormatString = us.DateTimeFormat.ShortTimePattern;
CultureInfo uk = new CultureInfo("en-GB");
string shortUkDateFormatString = uk.DateTimeFormat.ShortDatePattern;
string shortUkTimeFormatString = uk.DateTimeFormat.ShortTimePattern;
If you simply want to format the date/time using the CultureInfo
, pass it in as your IFormatter
when converting the DateTime
to a string, using the ToString
method:
string us = myDate.ToString(new CultureInfo("en-US"));
string uk = myDate.ToString(new CultureInfo("en-GB"));
The underlining problem is simple – lack of permission to /var/run/docker.sock
unix domain socket.
From Daemon socket option chapter of Docker Command Line reference for Docker 1.6.0:
By default, a unix domain socket (or IPC socket) is created at
/var/run/docker.sock
, requiring either root permission, or docker group membership.
Steps necessary to grant rights to users are nicely described in Docker installation instructions for Fedora:
Granting rights to users to use Docker
The docker command line tool contacts the docker daemon process via a socket file
/var/run/docker.sock
owned byroot:root
. Though it's recommended to use sudo for docker commands, if users wish to avoid it, an administrator can create a docker group, have it own/var/run/docker.sock
, and add users to this group.
$ sudo groupadd docker
$ sudo chown root:docker /var/run/docker.sock
$ sudo usermod -a -G docker $USERNAME
Log out and log back in for above changes to take effect.
Please note that Docker packages of some Linux distributions (Ubuntu) do already place /var/run/docker.sock
in the docker
group making the first two of above steps unnecessary.
In case of OS X and boot2docker
the situation is different; the Docker daemon runs inside a VM so the DOCKER_HOST
environment variable must be set to this VM so that the Docker client could find the Docker daemon. This is done by running $(boot2docker shellinit)
in the shell.

res.writeHead(404, {'Content-Type': 'text/plain' });
res.end('404 Not Found');
return;

In my case, I used a callback in yaxis ticks, my values are in percent and when it reaches 100% it doesn't show the dot, I used this :
yAxes: [{
ticks: {
beginAtZero: true,
steps: 10,
stepValue: 5,
min: 0,
max: 100.1,
callback: function(value, index, values) {
if (value !== 100.1) {
return values[index]
}
}
}
}],
And it worked well.
I have been using generic-pool with redis connections in my app - I highly recommend it. Its generic and I definitely know it works with mysql so I don't think you'll have any problems with it and mongo
Can you try this,
echo date("Y-m-d H:i:s", 1388516401);
As noted by theGame,
This means that you pass in a string value for the time, and optionally a value for the current time, which is a UNIX timestamp. The value that is returned is an integer which is a UNIX timestamp.
echo strtotime("2014-01-01 00:00:01");
This will return into the value 1388516401, which is the UNIX timestamp for the date 2014-01-01. This can be confirmed using the date() function as like below:
echo date('Y-m-d', 1198148400); // echos 2014-01-01
Your struct can have methods and properties... why not try
public struct MyStruct {
public string s;
public int length { return s.Length; }
}
Correction @Guffa's answer shows that it is possible... more info here: http://www.codeproject.com/KB/cs/Csharp_implicit_operator.aspx
You can hit the key q (for quit) and it should take you to the prompt.
Please see this link.
See Converting unix timestamp to excel date-time forum thread.
In actionPerformed(ActionEvent e)
you call encrypt()
, which is declared to throw Exception
. However, actionPerformed
neither catches this Exception (with try/catch around the call to encrypt()
) nor declares that it throws Exception
itself.
Your encrypt
method, however, does not truly throw Exception
. It swallows all Exceptions without even as much as logging a complaint. (Bad practice and bad style!)
Also, your encrypt
method does the following:
public static byte[] encrypt(String toEncrypt) throws Exception {
try{
....
return encrypted; // HERE YOU CORRECTLY RETURN A VALUE
} catch(Exception e) {
}
// YOU DO NOT RETURN ANYTHING HERE
}
That is, if you do catch any Exception, you discard it silently and then fall off the bottom of your encrypt
method without actually returning anything. This won't compile (as you see), because a method that is declared to return a value must either return a value or throw an Exception for every single possible code path.
How about using grep -E
?
echo "This is 02G05 a test string 20-Jul-2012" | grep -Eo '[0-9]+G[0-9]+'
Update:
Separate the event and property bindings:
<select [ngModel]="selectedItem" (ngModelChange)="onChange($event)">
onChange(newValue) {
console.log(newValue);
this.selectedItem = newValue; // don't forget to update the model here
// ... do other stuff here ...
}
You could also use
<select [(ngModel)]="selectedItem" (ngModelChange)="onChange($event)">
and then you wouldn't have to update the model in the event handler, but I believe this causes two events to fire, so it is probably less efficient.
Old answer, before they fixed a bug in beta.1:
Create a local template variable and attach a (change)
event:
<select [(ngModel)]="selectedItem" #item (change)="onChange(item.value)">
See also How can I get new selection in "select" in Angular 2?
Define extension: String+Extension.ts
interface String {
toBoolean(): boolean
}
String.prototype.toBoolean = function (): boolean {
switch (this) {
case 'true':
case '1':
case 'on':
case 'yes':
return true
default:
return false
}
}
And import in any file where you want to use it '@/path/to/String+Extension'
It's not an issue related to authentication at the first step. Your import
is not working. So, try writing this on first line:
#!/usr/bin/python
and for the time being run using
python xx.py
For you here is one explanation:
>>> abc = "Hei Buddy"
>>> print "%s" %abc
Hei Buddy
>>>
>>> print "%s" %xyz
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
print "%s" %xyz
NameError: name 'xyz' is not defined
At first, I initialized abc variable and it works fine. On the otherhand, xyz doesn't work as it is not initialized!
This will have the field take 50% of the width and be centered and resized properly
{ width: 50%; margin-left : 25% }
May also use "vw" (view width) units instead of "%"
If you are just trying to open a file, you could use app.open_resource()
. So reading a file would look something like
with app.open_resource('/static/path/yourfile'):
#code to read the file and do something
In Swift 4.2: You can use
myArray.append("Tim") //To add "Tim" into array
or
myArray.insert("Tim", at: 0) //Change 0 with specific location
This answer is outdated. You can do this a lot more simply, as pointed out in another answer below:
ul {
list-style-position: outside;
}
See https://www.w3schools.com/cssref/pr_list-style-position.asp
I'm surprised to see this hasn't been solved yet. You can make use of the browser's table layout algorithm (without using tables) like this:
ol {
counter-reset: foo;
display: table;
}
ol > li {
counter-increment: foo;
display: table-row;
}
ol > li::before {
content: counter(foo) ".";
display: table-cell; /* aha! */
text-align: right;
}

If you are migrated for AndroidX and getting this error, you need to set the compile SDK to Android 9.0 (API level 28) or higher
I know this question already has an accepted answer, but the Apache documentation says:
The Allow, Deny, and Order directives, provided by mod_access_compat, are deprecated and will go away in a future version. You should avoid using them, and avoid outdated tutorials recommending their use.
So, a more future-proof answer would be:
<RequireAll>
Require ip xx.xx.xx.xx yy.yy.yy.yy
</RequireAll>
Hopefully, I've helped prevent this page from becoming one of those "outdated tutorials". :)
Use a BigDecimal. It even lets you specify rounding rules (like ROUND_HALF_EVEN, which will minimize statistical error by rounding to the even neighbor if both are the same distance; i.e. both 1.5 and 2.5 round to 2).

Please see stopwatch.js for a very clean and simple Vanilla Javascript ES6 solution.
try like this,
ans = str.split (":");
And you can use two parts of the string like,
ans[0] and ans[1]
You can use also "void*" (void pointer) to send an address to the function.
typedef struct pstring_t {
char * chars;
int(*length)(void*);
} PString;
int length(void* self) {
return strlen(((PString*)self)->chars);
}
PString initializeString() {
PString str;
str.length = &length;
return str;
}
int main()
{
PString p = initializeString();
p.chars = "Hello";
printf("Length: %i\n", p.length(&p));
return 0;
}
Output:
Length: 5
If you give generally give a span

You can also skip the div

and apply the backgound style to it.
<a href="" class="myImage"><!----></a>
<style>
.myImage {display: block; width: 160px; height: 20px; margin:0 0 10px 0; background: url(image.png) center top no-repeat;}
.myImage:hover{background-image(image_hover.png);}

Here is my really simple solution. Use the gmatch function to capture strings which contain at least one character of anything other than the desired separator. The separator is **any* whitespace (%s in Lua) by default:
function mysplit (inputstr, sep)
if sep == nil then
sep = "%s"
end
local t={}
for str in string.gmatch(inputstr, "([^"..sep.."]+)") do
table.insert(t, str)
end
return t
end
.
try this:
but.onclick = callJavascriptFunction;
or create the button by wrapping it with another element and use innerHTML:
var span = document.createElement('span');
span.innerHTML = '<button id="but' + inc +'" onclick="callJavascriptFunction()" />';
I don't think there is a way to do that out-of-the-box. A possibly cleaner solution would be:
Stream.of(objects)
.filter(c -> c instanceof Client)
.map(c -> (Client) c)
.map(Client::getID)
.forEach(System.out::println);
or, as suggested in the comments, you could use the cast
method - the former may be easier to read though:
Stream.of(objects)
.filter(Client.class::isInstance)
.map(Client.class::cast)
.map(Client::getID)
.forEach(System.out::println);
A new way to get this problem has appeared as of Visual Studio 2017 15.3.1 through 15.3.5. If you are using EditorConfig, the charset=utf8
option causes these symptoms. The VS team has reproduced this and says they are working on it.
So one fix is to comment out your charset=utf8
line in the .editorconfig file.
Edit: This should be fixed as of VS 15.5.
You can access columns by index, by name and some other ways:
dtResult.Rows(i)("columnName") = strVerse
You should probably make sure your DataTable
has some columns first...
I got the following message, similar to your one:
program: malloc.c:2372: sysmalloc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 *(sizeof(size_t))) - 1)) & ~((2 *(sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long) old_end & pagemask) == 0)' failed.
Made a mistake some method call before, when using malloc. Erroneously overwrote the multiplication sign '*' with a '+', when updating the factor after sizeof()-operator on adding a field to unsigned char array.
Here is the code responsible for the error in my case:
UCHAR* b=(UCHAR*)malloc(sizeof(UCHAR)+5); b[INTBITS]=(some calculation); b[BUFSPC]=(some calculation); b[BUFOVR]=(some calculation); b[BUFMEM]=(some calculation); b[MATCHBITS]=(some calculation);
In another method later, I used malloc again and it produced the error message shown above. The call was (simple enough):
UCHAR* b=(UCHAR*)malloc(sizeof(UCHAR)*50);
Think using the '+'-sign on the 1st call, which lead to mis-calculus in combination with immediate initialization of the array after (overwriting memory that was not allocated to the array), brought some confusion to malloc's memory map. Therefore the 2nd call went wrong.
You can use (':hidden') method to find if your div is visible or not.. Also its a good practice to cache a element if you are using it multiple times in your code..
$(".subpanel a").click(function()
{
var chatterNickname = $(this).text();
var $chatPanel = $("#singlechatpanel-1");
if(!$chatPanel.is(':hidden'))
{
alert("Room 1 is filled.");
$chatPanel.show();
$("#singlechatpanel-1 #chatter_nickname").html("Chatting with: " + chatterNickname);
}
});
Kotlin way
editText.setOnFocusChangeListener { _, hasFocus ->
if (!hasFocus) { }
}
Old question, but another "pure razor" answer would be:
@Html.CheckBoxFor(model => model.As, htmlAttributes: new { @checked = true} )
I liked the solution in the earlier post.
I made a mini-class, called it class AlphabeticalHash
. It also has a method called ap
, which accepts one argument, a Hash
, as input: ap variable
. Akin to pp (pp variable
)
But it will (try and) print in alphabetical list (its keys). Dunno if anyone else wants to use this, it's available as a gem, you can install it as such: gem install alphabetical_hash
For me, this is simple enough. If others need more functionality, let me know, I'll include it into the gem.
EDIT: Credit goes to Peter, who gave me the idea. :)
Looks like your buttons are not declared correctly (according to the latest jQuery UI documentation anyway).
try the following:
$( ".selector" ).dialog({
buttons: [{
text: "Ok",
click: function() {
$( this ).dialog( "close" );
}
}]
});
The Resource
class also has a method getDimensionPixelSize() which I think will fit your needs.

When adding support for mimetype (as suggested by @ProVega) then it is also best practice to remove the type before adding it - this is to prevent unexpected errors when deploying to servers where support for the type already exists, for example:
<staticContent>
<remove fileExtension=".json" />
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
After spending some time reading over a couple different threads that seemed pretty complicated I came up with this. I needed it for an 8 core machine where I wanted to monitor SQL server. For the code below then I passed in "sqlservr" as appName.
private static void RunTest(string appName)
{
bool done = false;
PerformanceCounter total_cpu = new PerformanceCounter("Process", "% Processor Time", "_Total");
PerformanceCounter process_cpu = new PerformanceCounter("Process", "% Processor Time", appName);
while (!done)
{
float t = total_cpu.NextValue();
float p = process_cpu.NextValue();
Console.WriteLine(String.Format("_Total = {0} App = {1} {2}%\n", t, p, p / t * 100));
System.Threading.Thread.Sleep(1000);
}
}
It seems to correctly measure the % of CPU being used by SQL on my 8 core server.
Using jQuery:
var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
var jsonObj = $.parseJSON('[' + str + ']');
jsonObj
is your JSON object.
I am using Intents to communicate actions back to the main activity. The main activity is listening to these by overriding onNewIntent(Intent intent). The main activity translates these actions to the corresponding fragments for example.
So you can do something like this:
public class MainActivity extends Activity {
public static final String INTENT_ACTION_SHOW_FOO = "show_foo";
public static final String INTENT_ACTION_SHOW_BAR = "show_bar";
@Override
protected void onNewIntent(Intent intent) {
routeIntent(intent);
}
private void routeIntent(Intent intent) {
String action = intent.getAction();
if (action != null) {
switch (action) {
case INTENT_ACTION_SHOW_FOO:
// for example show the corresponding fragment
loadFragment(FooFragment);
break;
case INTENT_ACTION_SHOW_BAR:
loadFragment(BarFragment);
break;
}
}
}
Then inside any fragment to show the foo fragment:
Intent intent = new Intent(context, MainActivity.class);
intent.setAction(INTENT_ACTION_SHOW_FOO);
// Prevent activity to be re-instantiated if it is already running.
// Instead, the onNewEvent() is triggered
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
getContext().startActivity(intent);

That's the default margin/padding of the body
element.
Some browsers have a default margin, some a default padding, and both are applied as a padding in the body element.
Add this to your CSS:
body { margin: 0; padding: 0; }
Credit for this goes to magma. Great answer, but here it is using c++ style strings instead of c style strings. Some users may find that easier.
String string = "";
char ch; // Where to store the character read
void setup() {
Serial.begin(9600);
Serial.write("Power On");
}
boolean Comp(String par) {
while (Serial.available() > 0) // Don't read unless
// there you know there is data
{
ch = Serial.read(); // Read a character
string += ch; // Add it
}
if (par == string) {
string = "";
return(true);
}
else {
//dont reset string
return(false);
}
}
void loop()
{
if (Comp("m1 on")) {
Serial.write("Motor 1 -> Online\n");
}
if (Comp("m1 off")) {
Serial.write("Motor 1 -> Offline\n");
}
}
You can fix this by starting the service manually.

Assuming that you are using UTF-8 encoding:
string convert = "This is the string to be converted";
// From string to byte array
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(convert);
// From byte array to string
string s = System.Text.Encoding.UTF8.GetString(buffer, 0, buffer.Length);
Try assigning a value to $aug1
before use it in if[]
statements; the error message will disappear afterwards.
As of Spark 2.0.0, you can do the following.
Let's define a Person
case class:
scala> case class Person(id: Int, name: String)
defined class Person
Import spark
SparkSession implicit Encoders
:
scala> import spark.implicits._
import spark.implicits._
And use SparkSession to create an empty Dataset[Person]
:
scala> spark.emptyDataset[Person]
res0: org.apache.spark.sql.Dataset[Person] = [id: int, name: string]
You could also use a Schema "DSL" (see Support functions for DataFrames in org.apache.spark.sql.ColumnName).
scala> val id = $"id".int
id: org.apache.spark.sql.types.StructField = StructField(id,IntegerType,true)
scala> val name = $"name".string
name: org.apache.spark.sql.types.StructField = StructField(name,StringType,true)
scala> import org.apache.spark.sql.types.StructType
import org.apache.spark.sql.types.StructType
scala> val mySchema = StructType(id :: name :: Nil)
mySchema: org.apache.spark.sql.types.StructType = StructType(StructField(id,IntegerType,true), StructField(name,StringType,true))
scala> import org.apache.spark.sql.Row
import org.apache.spark.sql.Row
scala> val emptyDF = spark.createDataFrame(sc.emptyRDD[Row], mySchema)
emptyDF: org.apache.spark.sql.DataFrame = [id: int, name: string]
scala> emptyDF.printSchema

First, you need to compile your code with appropriate flags, enabling debug into code.
$ gcc -Wall -g -ggdb -o ex1 ex1.c
then just run you code with your favourite debugger
$ gdb ./ex1
show me the code.
(gdb) list

3 {
4 int i = 0;
5 for(i=0;i<7;++i)
6 printf("%d\n", i);

Yes, it is possible:

}
public Foo(int x) {
this.x = x;

}
To chain to a particular superclass constructor instead of one in the same class, use super
instead of this
. Note that you can only chain to one constructor, and it has to be the first statement in your constructor body.

I see some of the above answers are now a bit out of date. From my perspective, and I work with both Solr(Cloud and non-Cloud) and ElasticSearch on a daily basis, here are some interesting differences:
For more thorough coverage of Solr vs. ElasticSearch topic have a look at https://sematext.com/blog/solr-vs-elasticsearch-part-1-overview/ . This is the first post in the series of posts from Sematext doing direct and neutral Solr vs. ElasticSearch comparison. Disclosure: I work at Sematext.
Android 4.4 (KitKat) and higher devices have a shell utility for recording the Android device screen. Connect a device in developer/debug mode running KitKat with the adb utility over USB and then type the following:
adb shell screenrecord /sdcard/movie.mp4
(Press Ctrl-C to stop)
adb pull /sdcard/movie.mp4
Screen recording is limited to a maximum of 3 minutes.

Did you dump your master gc log? So I met similar issue and I found SPARK_DRIVER_MEMORY only set the Xmx heap. The initial heap size remains 1G and the heap size never scale up to the Xmx heap.

Angular has several timepoints to start executing functions. If you seek for something like jQuery's
$(document).ready();
You may find this analog in angular to be very useful:
$scope.$watch('$viewContentLoaded', function(){
//do something
});
This one is helpful when you want to manipulate the DOM elements. It will start executing only after all te elements are loaded.
UPD: What is said above works when you want to change css properties. However, sometimes it doesn't work when you want to measure the element properties, such as width, height, etc. In this case you may want to try this:
$scope.$watch('$viewContentLoaded',
function() {
$timeout(function() {
//do something
},0);
});
It's more convenient to use a session, this way you don't have to remember to set headers each time:
session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})
session.get('https://httpbin.org/headers')
By default, session also manages cookies for you. In case you want to disable that, see this question.
From the Errata:
ModelState.AddRuleViolations(dinner.GetRuleViolations());
Should be:
ModelState.AddModelErrors(dinner.GetRuleViolations());
Try gcc -c -I/home/me/development/skia sample.c
.
My site configuration file is example.conf in sites-available folder So you can create a symbolic link as
ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/
You can also do this at the beginning of the query:
SET ARITHABORT OFF
SET ANSI_WARNINGS OFF
So if you have something like 100/0
it will return NULL. I've only done this for simple queries, so I don't know how it will affect longer/complex ones.
It says timer() is not available on android? You might find this article useful.
http://developer.android.com/resources/articles/timed-ui-updates.html
I was wrong. Timer() is available. It seems you either implement it the way it is one shot operation:
schedule(TimerTask task, Date when) // Schedule a task for single execution.
Or you cancel it after the first execution:
cancel() // Cancels the Timer and all scheduled tasks.
Concise if you are just interested in the time elapsed that is under 24 hours. You can format the output as needed in the return statement :
import datetime
def elapsed_interval(start,end):
elapsed = end - start
min,secs=divmod(elapsed.days * 86400 + elapsed.seconds, 60)
hour, minutes = divmod(min, 60)
return '%.2d:%.2d:%.2d' % (hour,minutes,secs)
if __name__ == '__main__':
time_start=datetime.datetime.now()
""" do your process """
time_end=datetime.datetime.now()
total_time=elapsed_interval(time_start,time_end)

If you're looking for an alternative that doesn't involve a third-party library (e.g. Commons I/O), you can use the Scanner class:
private String readFile(String pathname) throws IOException {
File file = new File(pathname);
StringBuilder fileContents = new StringBuilder((int)file.length());
try (Scanner scanner = new Scanner(file)) {
while(scanner.hasNextLine()) {
fileContents.append(scanner.nextLine() + System.lineSeparator());
}
return fileContents.toString();
}
}
I figured it out. Need to use echo in PHP instead of return.
<?php
$output = some_function();
echo $output;
?>
And the jQ:
success: function(data) {
doSomething(data);
}
Inside testing2.php
you should print the $_POST
array which contains all the data from the post. Also, $_POST['name']
should be available. For more info check $_POST on php.net.
URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
new InputStreamReader(
yahoo.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
I'll mention the more obvious way of dealing with duplicates in lists. In terms of complexity, dictionaries are the way to go because each lookup is O(1). You can be more clever if you're only interested in duplicates...
my_list = [1,1,2,3,4,5,5]
my_dict = {}
for (ind,elem) in enumerate(my_list):
if elem in my_dict:
my_dict[elem].append(ind)
else:
my_dict.update({elem:[ind]})
for key,value in my_dict.iteritems():
if len(value) > 1:
print "key(%s) has indices (%s)" %(key,value)
which prints the following:
key(1) has indices ([0, 1])
key(5) has indices ([5, 6])
Unless there is some compelling reason to use a regex, I would just use String.startsWith:
bool matches = test.startsWith("http://")
|| test.startsWith("https://")
|| test.startsWith("ftp://");
I wouldn't be surprised if this is faster, too.
sounds like you downloaded the german xampp package instead of the english xampp package (yes, it's another download-link) where the language is set according to the package you loaded. to change the language afterwards, simply edit the config.inc.php
and set:
$cfg['Lang'] = 'en-utf-8';
xml:space="preserve"
Works like a charm.
Edit: Wrong. Actually, it only works when the content is comprised of white spaces only.

When dealing with situations where I don't exactly know what type of exception might come out of a method, a little "trick" I like to do is to recover the Exception's class name and add it to the error log so there is more information.
try
{
<code>
} catch ( Exception caughtEx )
{
throw new Exception("Unknown Exception Thrown: "
+ "\n Type: " + caughtEx.GetType().Name
+ "\n Message: " + caughtEx.Message);
}
I do vouch for always handling Exceptions types individually, but the extra bit of info can be helpful, specially when dealing with code from people who love to capture catch-all generic types.
StringBuilder sb = new StringBuilder(name);
sb.setCharAt(0, Character.toUpperCase(sb.charAt(0)));
return sb.toString();
here is an easy way to use join.
''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))
Method 1
Using new keyword. This is the most common way to create an object in java. Almost 99% of objects are created in this way.
Employee object = new Employee();
Method 2
Using Class.forName(). Class.forName() gives you the class object, which is useful for reflection. The methods that this object has are defined by Java, not by the programmer writing the class. They are the same for every class. Calling newInstance() on that gives you an instance of that class (i.e. callingClass.forName("ExampleClass").newInstance() it is equivalent to calling new ExampleClass()), on which you can call the methods that the class defines, access the visible fields etc.
Employee object2 = (Employee) Class.forName(NewEmployee).newInstance();
Class.forName() will always use the ClassLoader of the caller, whereas ClassLoader.loadClass() can specify a different ClassLoader. I believe that Class.forName initializes the loaded class as well, whereas the ClassLoader.loadClass() approach doesn’t do that right away (it’s not initialized until it’s used for the first time).
Another must read:
Java: Thread State Introduction with Example Simple Java Enum Example
Method 3
Using clone(). The clone() can be used to create a copy of an existing object.
Employee secondObject = new Employee();
Employee object3 = (Employee) secondObject.clone();
Method 4
Using newInstance() method
Object object4 = Employee.class.getClassLoader().loadClass(NewEmployee).newInstance();
Method 5
Using Object Deserialization. Object Deserialization is nothing but creating an object from its serialized form.
// Create Object5
// create a new file with an ObjectOutputStream
FileOutputStream out = new FileOutputStream("");
ObjectOutputStream oout = new ObjectOutputStream(out);
// write something in the file
oout.writeObject(object3);
oout.flush();
// create an ObjectInputStream for the file we created before
ObjectInputStream ois = new ObjectInputStream(new FileInputStream("crunchify.txt"));
Employee object5 = (Employee) ois.readObject();
I'm a little surprised that this question has been asked so many times before, but the most reuseable and friendly solution hasn't been documented.
I often have webpages using AngularJS, and when I click on a Save button, I'll "POST" this data back to my .aspx page or .ashx handler to save this back to the database. The data will be in the form of a JSON record.
On the server, to turn the raw posted data back into a C# class, here's what I would do.
First, define a C# class which will contain the posted data.
Supposing my webpage is posting JSON data like this:
{
"UserID" : 1,
"FirstName" : "Mike",
"LastName" : "Mike",
"Address1" : "10 Really Street",
"Address2" : "London"
}
Then I'd define a C# class like this...
public class JSONRequest
{
public int UserID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
}
(These classes can be nested, but the structure must match the format of the JSON data. So, if you're posting a JSON User record, with a list of Order records within it, your C# class should also contain a List<>
of Order records.)
Now, in my .aspx.cs or .ashx file, I just need to do this, and leave JSON.Net to do the hard work...
protected void Page_Load(object sender, EventArgs e)
{
string jsonString = "";
HttpContext.Current.Request.InputStream.Position = 0;
using (StreamReader inputStream = new StreamReader(this.Request.InputStream))
{
jsonString = inputStream.ReadToEnd();
}
JSONRequest oneQuestion = JsonConvert.DeserializeObject<JSONRequest>(jsonString);
And that's it. You now have a JSONRequest
class containing the various fields which were POSTed to your server.
If you want to temporarily revert changes because
You can search for the last working commit using git log
and then run:
git rebase --onto <commitId>
When the remote branch is working again, you can
git pull --rebase
This method is better than git checkout
for temporary changes, because you're not in a detached state.
You are right, it's confusing that SQL Server allows you to create duplicate indexes on the same field(s). But the fact that you can create another doesn't indicate that the PK index doesn't also already exist.
The additional index does no good, but the only harm (very small) is the additional file size and row-creation overhead.
public class SubstringExample
{
public static void main(String[] args)
{
String str="OOPs is a programming paradigm...";
System.out.println(" Length is: " + str.length());
System.out.println(" Substring is: " + str.substring(10, 30));
}
}
Output:
length is: 31
Substring is: programming paradigm
Agree with Subir Kumar Sao and Faiz.

The best way to send data from a parent component to a child is using props.
props
props
(array or object) in the child<child :name="variableOnParent">
See demo below:
Vue.component('child-comp', {
props: ['message'], // declare the props
template: '<p>At child-comp, using props in the template: {{ message }}</p>',
mounted: function () {
console.log('The props are also available in JS:', this.message);
}
})
new Vue({
el: '#app',
data: {
variableAtParent: 'DATA FROM PARENT!'
}
})
_x000D_
<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>
<div id="app">
<p>At Parent: {{ variableAtParent }}<br>And is reactive (edit it) <input v-model="variableAtParent"></p>
<child-comp :message="variableAtParent"></child-comp>
</div>

At the beginning of your file you set raw_input
to 0. Do not do this, at it modifies the built-in raw_input()
function. Therefore, whenever you call raw_input()
, it is essentially calling 0()
, which raises the error. To remove the error, remove the first line of your code:

This can be done without terminal, directly from IDE. Netbeans, for example.
I figured it out. I was using a bad example I found in the past of how to map query string to the method parameters.
In case anyone else needs it, in order to have optional parameters in a query string such as:
you would use:
[Route("products/filter/{apc?}/{xpc?}/{sku?}")]
public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }
It seems odd to have to define default values for the method parameters when these types already have a default.
If you're going across machines, you either need to be using NETWORK SERVICE, LOCAL SYSTEM, a domain account, or a SQL 2008 R2 (if you have it) Managed Service Account (which is my preference if you had such an infrastructure). You can not use an account which is not visible to the Active Directory domain.
public static bool[] Convert(int[] input, int length)
{
var ret = new bool[length];
var siz = sizeof(int) * 8;
var pow = 0;
var cur = 0;
for (var a = 0; a < input.Length && cur < length; ++a)
{
var inp = input[a];
pow = 1;
if (inp > 0)
{
for (var i = 0; i < siz && cur < length; ++i)
{
ret[cur++] = (inp & pow) == pow;
pow *= 2;
}
}
else
{
for (var i = 0; i < siz && cur < length; ++i)
{
ret[cur++] = (inp & pow) != pow;
pow *= 2;
}
}
}
return ret;
}
You can do this with a table value parameters.
Have a look at the following article:
http://www.codeproject.com/Articles/39161/C-and-Table-Value-Parameters
def nested1(num1):
print "nested1 has",num1
def nested2(num2):
print "nested2 has",num2,"and it can reach to",num1
return num1+num2 #num1 referenced for reading here
return nested2
Gives:
In [17]: my_func=nested1(8)
nested1 has 8
In [21]: my_func(5)
nested2 has 5 and it can reach to 8
Out[21]: 13
This is an example of what a closure is and how it can be used.
Flyway library is really good for this:
Flyway flyway = new Flyway();
flyway.setDataSource(dbConfig.getUrl(), dbConfig.getUsername(), dbConfig.getPassword());
flyway.setLocations("classpath:db/scripts");
flyway.clean();
flyway.migrate();
This scans the locations for scripts and runs them in order. Scripts can be versioned with V01__name.sql so if just the migrate is called then only those not already run will be run. Uses a table called 'schema_version' to keep track of things. But can do other things too, see the docs: flyway.
The clean call isn't required, but useful to start from a clean DB. Also, be aware of the location (default is "classpath:db/migration"), there is no space after the ':', that one caught me out.
You can create a PrintStream wrapping around your OutputStream and then just call it's print(String):
final OutputStream os = new FileOutputStream("/tmp/out");
final PrintStream printStream = new PrintStream(os);
printStream.print("String");
printStream.close();
I think that's up to you to show that dialog for choosing. For Gallery you'll use that code, and for Camera try this.
I have referred this github post and I have set the three layouts
for three fragment
pages in bottom tab bar.
FourButtonsActivity.java:
bottomBar.setFragmentItems(getSupportFragmentManager(), R.id.fragmentContainer,
new BottomBarFragment(LibraryFragment.newInstance(R.layout.library_fragment_layout), R.drawable.ic_update_white_24dp, "Recents"),
new BottomBarFragment(PhotoEffectFragment.newInstance(R.layout.photo_effect_fragment), R.drawable.ic_local_dining_white_24dp, "Food"),
new BottomBarFragment(VideoFragment.newInstance(R.layout.video_layout), R.drawable.ic_favorite_white_24dp, "Favorites")
);
To set the badge count :
BottomBarBadge unreadMessages = bottomBar.makeBadgeForTabAt(1, "#E91E63", 4);
unreadMessages.show();
unreadMessages.setCount(4);
unreadMessages.setAnimationDuration(200);
unreadMessages.setAutoShowAfterUnSelection(true);
LibraryFragment.java:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class LibraryFragment extends Fragment {
private static final String STARTING_TEXT = "Four Buttons Bottom Navigation";
public LibraryFragment() {
}
public static LibraryFragment newInstance(int resource) {
Bundle args = new Bundle();
args.putInt(STARTING_TEXT, resource);
LibraryFragment sampleFragment = new LibraryFragment();
sampleFragment.setArguments(args);
return sampleFragment;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = LayoutInflater.from(getActivity()).inflate(
getArguments().getInt(STARTING_TEXT), null);
return view;
}
To force a reload of the php.ini you should restart apache.
Try sudo service apache2 restart
from the command line.
Or sudo /etc/init.d/apache2 restart
The bottom statement is equivalent to:
.half {
flex-grow: 0;
flex-shrink: 0;
flex-basis: 50%;
}
Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.
Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.
I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)
Yes, it is. You can write :
INSERT INTO courses (name, location, gid)
SELECT name, location, 'whatever you want'
FROM courses
WHERE cid = $ci
or you can get values from another join of the select ...
I assume 0
means false
(which is the case in a lot of programming languages). That means true
is not 0
(some languages use -1
some others use 1
; doesn't hurt to be compatible to either). So assuming by "better" you mean less typing, you can just write:
bool boolValue = intValue != 0;
use the configuration below;

Are you escaping it with \

Here's a helpful resource to get started with Regular Expressions:
There are different ways to do this some of them has given.
implode(), join(), var_export(), print_r(), serialize(), json_encode()
exc... You can also write your own function without these:
A For()
loop is very useful. You can add your array's value to another variable like this:
<?php
$dizi=array('mother','father','child'); //This is array
$sayi=count($dizi);
for ($i=0; $i<$sayi; $i++) {
$dizin.=("'$dizi[$i]',"); //Now it is string...
}
echo substr($dizin,0,-1); //Write it like string :D
?>
In this code we added $dizi's values and comma to $dizin:
$dizin.=("'$dizi[$i]',");
Now
$dizin = 'mother', 'father', 'child',
It's a string, but it has an extra comma :)
And then we deleted the last comma, substr($dizin, 0, -1);
Output:
'mother','father','child'
When you add an object to $stateProvider.state
that object is then passed with the state. So you can add additional properties which you can read later on when needed.
Example route configuration
$stateProvider
.state('public', {
abstract: true,
module: 'public'
})
.state('public.login', {
url: '/login',
module: 'public'
})
.state('tool', {
abstract: true,
module: 'private'
})
.state('tool.suggestions', {
url: '/suggestions',
module: 'private'
});
The $stateChangeStart
event gives you acces to the toState
and fromState
objects. These state objects will contain the configuration properties.
Example check for the custom module property
$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
if (toState.module === 'private' && !$cookies.Session) {
// If logged out and transitioning to a logged in page:
e.preventDefault();
$state.go('public.login');
} else if (toState.module === 'public' && $cookies.Session) {
// If logged in and transitioning to a logged out page:
e.preventDefault();
$state.go('tool.suggestions');
};
});
I didn't change the logic of the cookies because I think that is out of scope for your question.
You can create a Helper to get you this to work more modular.
Value publicStates
myApp.value('publicStates', function(){
return {
module: 'public',
routes: [{
name: 'login',
config: {
url: '/login'
}
}]
};
});
Value privateStates
myApp.value('privateStates', function(){
return {
module: 'private',
routes: [{
name: 'suggestions',
config: {
url: '/suggestions'
}
}]
};
});
The Helper
myApp.provider('stateshelperConfig', function () {
this.config = {
// These are the properties we need to set
// $stateProvider: undefined
process: function (stateConfigs){
var module = stateConfigs.module;
$stateProvider = this.$stateProvider;
$stateProvider.state(module, {
abstract: true,
module: module
});
angular.forEach(stateConfigs, function (route){
route.config.module = module;
$stateProvider.state(module + route.name, route.config);
});
}
};
this.$get = function () {
return {
config: this.config
};
};
});
Now you can use the helper to add the state configuration to your state configuration.
myApp.config(['$stateProvider', '$urlRouterProvider',
'stateshelperConfigProvider', 'publicStates', 'privateStates',
function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
helper.config.$stateProvider = $stateProvider;
helper.process(publicStates);
helper.process(privateStates);
}]);
This way you can abstract the repeated code, and come up with a more modular solution.
Note: the code above isn't tested

I had struggled with the similar issue and sharing the solution accordingly. We use a mongo replica set and mongo service on my secondary server was taking too long to start. (approx 10-15 minutes)
Couldn't find anything until attempted to configure the mongo with some different folder in --dbpath And that worked fine, so we got to know that the earlier path, which was a mount directory had some issues. So followed with nss team to get the network mount issue solved.
Hope this helps someone
I used axios-mock-adapter. In this case the service is described in ./chatbot. In the mock adapter you specify what to return when the API endpoint is consumed.
import axios from 'axios';
import MockAdapter from 'axios-mock-adapter';
import chatbot from './chatbot';
describe('Chatbot', () => {
it('returns data when sendMessage is called', done => {
var mock = new MockAdapter(axios);
const data = { response: true };
mock.onGet('https://us-central1-hutoma-backend.cloudfunctions.net/chat').reply(200, data);
chatbot.sendMessage(0, 'any').then(response => {
expect(response).toEqual(data);
done();
});
});
});
You can see it the whole example here:
Service: https://github.com/lnolazco/hutoma-test/blob/master/src/services/chatbot.js
Test: https://github.com/lnolazco/hutoma-test/blob/master/src/services/chatbot.test.js
You can use the Session object
import requests
headers = {'User-Agent': 'Mozilla/5.0'}
payload = {'username':'niceusername','password':'123456'}
session = requests.Session()
session.post('https://admin.example.com/login.php',headers=headers,data=payload)
# the session instance holds the cookie. So use it to get/post later.
# e.g. session.get('https://example.com/profile')
Pure POSIX shell method, which unlike Roman Kazanovskyi's sed
-based answer needs no external tools, just the shell's own native parameter expansions. Note that long file names are minimized so the code fits better on one line:
f="I love Suzi and Marry"
s=Sara
t=Suzi
[ "${f%$t*}" != "$f" ] && f="${f%$t*}$s${f#*$t}"
echo "$f"
Output:
I love Sara and Marry
How it works:
Remove Smallest Suffix Pattern. "${f%$t*}"
returns "I love
" if the suffix $t
"Suzi*
" is in $f
"I love
Suzi and Marry
".
But if t=Zelda
, then "${f%$t*}"
deletes nothing, and returns the whole string "I love Suzi and Marry
".
This is used to test if $t
is in $f
with [ "${f%$t*}" != "$f" ]
which will evaluate to true if the $f
string contains "Suzi*
" and false if not.
If the test returns true, construct the desired string using Remove Smallest Suffix Pattern ${f%$t*}
"I love
" and Remove Smallest Prefix Pattern ${f#*$t}
"and Marry
", with the 2nd string $s
"Sara
" in between.
I had the same problem. I solved it by switching to <a>
and add onclick="return false;"
(so that clicking on it won't add a new entry to browser history).
The easiest solution I found was to simply put that in your fragment :
androidx.appcompat.widget.Toolbar toolbar = getActivity().findViewById(R.id.toolbar);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
NavController navController = Navigation.findNavController(getActivity(),
R.id.nav_host_fragment);
navController.navigate(R.id.action_position_to_destination);
}
});
Personnaly I wanted to go to another page but of course you can replace the 2 lines in the onClick method by the action you want to perform.
Simply:
String abc="abcdefghight";
byte[] b = abc.getBytes();
I've been playing with this same feature and found out that FF, IE, Chrome and Opera have the ability to provide the source element of an event. I haven't tested Safari but my guess is it might have something similar.
$('#Form').keyup(function (e) {
var ctrl = null;
if (e.originalEvent.explicitOriginalTarget) { // FF
ctrl = e.originalEvent.explicitOriginalTarget;
}
else if (e.originalEvent.srcElement) { // IE, Chrome and Opera
ctrl = e.originalEvent.srcElement;
}
//...
});
Using StringUtils from commons lang
A null source string will return null. An empty ("") source string will return the empty string. A null remove string will return the source string. An empty ("") remove string will return the source string.
String str = StringUtils.remove("Test remove", "remove");
System.out.println(str);
//result will be "Test"
From the Docker FAQ:
Docker is not a replacement for lxc. "lxc" refers to capabilities of the linux kernel (specifically namespaces and control groups) which allow sandboxing processes from one another, and controlling their resource allocations.
On top of this low-level foundation of kernel features, Docker offers a high-level tool with several powerful functionalities:
Portable deployment across machines. Docker defines a format for bundling an application and all its dependencies into a single object which can be transferred to any docker-enabled machine, and executed there with the guarantee that the execution environment exposed to the application will be the same. Lxc implements process sandboxing, which is an important pre-requisite for portable deployment, but that alone is not enough for portable deployment. If you sent me a copy of your application installed in a custom lxc configuration, it would almost certainly not run on my machine the way it does on yours, because it is tied to your machine's specific configuration: networking, storage, logging, distro, etc. Docker defines an abstraction for these machine-specific settings, so that the exact same docker container can run - unchanged - on many different machines, with many different configurations.
Application-centric. Docker is optimized for the deployment of applications, as opposed to machines. This is reflected in its API, user interface, design philosophy and documentation. By contrast, the lxc helper scripts focus on containers as lightweight machines - basically servers that boot faster and need less ram. We think there's more to containers than just that.
Automatic build. Docker includes a tool for developers to automatically assemble a container from their source code, with full control over application dependencies, build tools, packaging etc. They are free to use make, maven, chef, puppet, salt, debian packages, rpms, source tarballs, or any combination of the above, regardless of the configuration of the machines.
Versioning. Docker includes git-like capabilities for tracking successive versions of a container, inspecting the diff between versions, committing new versions, rolling back etc. The history also includes how a container was assembled and by whom, so you get full traceability from the production server all the way back to the upstream developer. Docker also implements incremental uploads and downloads, similar to "git pull", so new versions of a container can be transferred by only sending diffs.
Component re-use. Any container can be used as an "base image" to create more specialized components. This can be done manually or as part of an automated build. For example you can prepare the ideal python environment, and use it as a base for 10 different applications. Your ideal postgresql setup can be re-used for all your future projects. And so on.
Sharing. Docker has access to a public registry (https://registry.hub.docker.com/) where thousands of people have uploaded useful containers: anything from redis, couchdb, postgres to irc bouncers to rails app servers to hadoop to base images for various distros. The registry also includes an official "standard library" of useful containers maintained by the docker team. The registry itself is open-source, so anyone can deploy their own registry to store and transfer private containers, for internal server deployments for example.
Tool ecosystem. Docker defines an API for automating and customizing the creation and deployment of containers. There are a huge number of tools integrating with docker to extend its capabilities. PaaS-like deployment (Dokku, Deis, Flynn), multi-node orchestration (maestro, salt, mesos, openstack nova), management dashboards (docker-ui, openstack horizon, shipyard), configuration management (chef, puppet), continuous integration (jenkins, strider, travis), etc. Docker is rapidly establishing itself as the standard for container-based tooling.
I hope this helps!
valid json string must have double quote.

The main reason for that is using themes that are not supporting ActionBar:
In manifest file add the following either in your target activity or application element (if you want to unify the theme over whole application)
Examples of themes that are supporting action bar "Theme.AppCompat.Light"
or "Theme.Holo.Light"
...
android:theme="@android:style/Theme.Holo.Light"
It is better to put all styles in styles.xml
and use it everywhere using "@style/themName"
so the previous one will be
android:theme="@style/AppTheme"
and styles.xml will have the following:
<style name="AppTheme" parent="Theme.AppCompat.Light">
Hints:
"@android:style/Theme.Holo.Light.DarkActionBar"
is not supported before SDKs version 14.To allow your app to support minimum specific version of SDK you could add the following under <app>
element:
<uses-sdk android:minSdkVersion="14" />
To specify min SDK version in AndroidStudio, you could by using app's Gradle file.
android{
defaultConfig{
minSdkVersion 14
targetSdkVersion 21
}
}
If key
isn't an int
or float
but a str
ing, you need to convert it to an int
first by doing
key = int(key)
or to a float
by doing
key = float(key)
Otherwise, what you have in your question should work, but
if (key < 1) or (key > 34):
or
if not (1 <= key <= 34):
would be a bit clearer.
I'm confused by your question, seems to me that the question title and body are asking different things. If you want to disable/enable a click event on a div simply do:
$("#id").on('click', function(){ //enables click event
//do your thing here
});
$("#id").off('click'); //disables click event
If you want to disable a div, use the following code:
$("#id").attr('disabled','disabled');
Hope this helps.
edit: oops, didn't see the other bind/unbind answer. Sorry. Those methods are also correct, though they've been deprecated in jQuery 1.7, and replaced by on()/off()
Fetch does not use cookie by default. To enable cookie, do this:
fetch(url, {
credentials: "same-origin"
}).then(...).catch(...);
Though this question is a bit old...I was in a similar situation and my answer here helped me fix a similar issue I had
First try with push -f
or force option
If that did not work it is possible that (as in my case) the remote repositories (or rather the references to remote repositories that show up on git remote -v
) might not be getting updated.
Outcome of above being your push synced your local/branch with your remote/branch however, the cache in your local repo still shows previous commit (of local/branch ...provided only single commit was pushed) as HEAD.
To confirm the above clone the repo at a different location and try to compare local/branch HEAD and remote/branch HEAD. If they both are same then you are probably facing the issue I did.
Solution:
$ git remote -v
github [email protected]:schacon/hw.git (fetch)
github [email protected]:schacon/hw.git (push)
$ git remote add origin git://github.com/pjhyett/hw.git
$ git remote -v
github [email protected]:schacon/hw.git (fetch)
github [email protected]:schacon/hw.git (push)
origin git://github.com/pjhyett/hw.git (fetch)
origin git://github.com/pjhyett/hw.git (push)
$ git remote rm origin
$ git remote -v
github [email protected]:schacon/hw.git (fetch)
github [email protected]:schacon/hw.git (push)
Now do a push -f
as follows
git push -f github master
### Note your command does not have origin
anymore!
Do a git pull
now
git pull github master
on git status
receive
# On branch master
nothing to commit (working directory clean)
I hope this useful for someone as the number of views is so high that searching for this error almost always lists this thread on the top
Also refer gitref for details
php_flag display_errors on
To turn the actual display of errors on.
To set the types of errors you are displaying, you will need to use:
php_value error_reporting <integer>
Combined with the integer values from this page: http://php.net/manual/en/errorfunc.constants.php
Note if you use -1 for your integer, it will show all errors, and be future proof when they add in new types of errors.
While Guy's answer is correct (and probably fits 9 out of 10 cases), it's worth noting that if you are attempting to do this from a control that already has its DataContext set further up the stack, you'll resetting this when you set DataContext back to itself:
DataContext="{Binding RelativeSource={RelativeSource Self}}"
This will of course then break your existing bindings.
If this is the case, you should set the RelativeSource on the control you are trying to bind, rather than its parent.
i.e. for binding to a UserControl's properties:
Binding Path=PropertyName,
RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}
Given how difficult it can be currently to see what's going on with data binding, it's worth bearing this in mind even if you find that setting RelativeSource={RelativeSource Self}
currently works :)
I had the same issue in MIUI. Enabling OEM unlocking worked for me without disabling MIUI optimization.
Below is a screenshot of my Redmi 3s prime developer options setting:
As Johnathan Suggested, you would either want to save it in a cookie or a session.
The easier way would be to use a Session variable.
session_start();
if(!isset($_SESSION['org_referer']))
{
$_SESSION['org_referer'] = $_SERVER['HTTP_REFERER'];
}
Put that at the top of the page, and you will always be able to access the first referer that the site visitor was directed by.
Here is a working example of above. http://jsfiddle.net/z7L6m2sc/ Now select2 has been updated the classes have change may be why you cannot get it to work. Here is the css....
.select2-dropdown.select2-dropdown--below{

}
.select2-container--default .select2-selection--single{
padding:6px;

I think you could use the following HTML and CSS combo instead:
<li>
<a href="#">Backback</a>
</li>
Then use CSS background for the basket visibility on hover:
.listblock ul li a {
padding: 5px 30px 5px 10px;
display: block;
}
.listblock ul li a:hover {
background: transparent url('../img/basket.png') no-repeat 3px 170px;
}
Simples!
Yes, they do expire. There is an 'expires' value that is passed along with the 'access_token', and from what I can tell it's about 2 hours. I've been searching, but I don't see a way to request a longer expiration time.
${var@Q}
Under bash, you could store your variable content with Parameter Expansion's @
command for Parameter transformation:
${parameter@operator} Parameter transformation. The expansion is either a transforma- tion of the value of parameter or information about parameter itself, depending on the value of operator. Each operator is a single letter: Q The expansion is a string that is the value of parameter quoted in a format that can be reused as input. ... A The expansion is a string in the form of an assignment statement or declare command that, if evaluated, will recreate parameter with its attributes and value.
Sample:
$ var=$'Hello\nGood world.\n'
$ echo "$var"
Hello
Good world.
$ echo "${var@Q}"
$'Hello\nGood world.\n'
$ echo "${var@A}"
var=$'Hello\nGood world.\n'
There is a special printf
format directive (%q
) built for this kind of request:
printf [-v var] format [arguments]
%q causes printf to output the corresponding argument in a format that can be reused as shell input.
read foo
Hello world
printf "%q\n" "$foo"
Hello\ world
printf "%q\n" $'Hello world!\n'
$'Hello world!\n'
This could be used through variables too:
printf -v var "%q" "$foo
"
echo "$var"
$'Hello world\n'
Note that all bytes from 128 to 255 have to be escaped.
for i in {0..127} ;do
printf -v var \\%o $i
printf -v var $var
printf -v res "%q" "$var"
esc=E
[ "$var" = "$res" ] && esc=-
printf "%02X %s %-7s\n" $i $esc "$res"

So not always but sometime:
echo test 1, 2, 3 and 4,5.
test 1, 2, 3 and 4,5.
or
echo test { 1, 2, 3 }
test { 1, 2, 3 }
but care:
echo test{1,2,3}
test1 test2 test3
echo test\ {1,2,3}
test 1 test 2 test 3
echo test\ {\ 1,\ 2,\ 3\ }
test 1 test 2 test 3
echo test\ {\ 1\,\ 2,\ 3\ }
test 1, 2 test 3

I use the following static helper method to retrieve the IP of a client:
public static String getClientIpAddr(HttpServletRequest request) {
String ip = request.getHeader("X-Forwarded-For");
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("HTTP_X_FORWARDED_FOR");
}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("HTTP_X_FORWARDED");
}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("HTTP_X_CLUSTER_CLIENT_IP");
}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("HTTP_CLIENT_IP");
}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("HTTP_FORWARDED_FOR");
}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getHeader("HTTP_FORWARDED");

}
if (ip == null || ip.length() == 0 || ip.equalsIgnoreCase("unknown")) {
ip = request.getRemoteAddr();
}
return ip;

For android, I would use String android.net.Uri.encode(String s)
Encodes characters in the given string as '%'-escaped octets using the UTF-8 scheme. Leaves letters ("A-Z", "a-z"), numbers ("0-9"), and unreserved characters ("_-!.~'()*") intact. Encodes all other characters.
Ex/
String urlEncoded = "http://stackoverflow.com/search?q=" + Uri.encode(query);
To put it on one line:
currentLoad = IIf(IsNumeric(oXLSheet2.Cells(4, 6).Value), CInt(oXLSheet2.Cells(4, 6).Value), 0)
This one I found simple solutions:
row = myArray.map((cell, i) => {
if (i == myArray.length - 1) {
return <div> Test Data 1</div>;
}
return <div> Test Data 2</div>;
});
Use the substring method of the String class :
String removeCurrency=amount.getText().toString().substring(3);
You want:
for (i = 0; i < strlen(source); i++){
sizeof gives you the size of the pointer, not the string. However, it would have worked if you had declared the pointer as an array:
char source[] = "This is an example.";
but if you pass the array to function, that too will decay to a pointer. For strings it's best to always use strlen. And note what others have said about changing printf to use %c. And also, taking mmyers comments on efficiency into account, it would be better to move the call to strlen out of the loop:
int len = strlen( source );
for (i = 0; i < len; i++){
or rewrite the loop:
for (i = 0; source[i] != 0; i++){
With the tspan solution, let's say you don't know in advance where to put your line breaks: you can use this nice function, that I found here: http://bl.ocks.org/mbostock/7555321
That automatically does line breaks for long text svg for a given width in pixel.
function wrap(text, width) {
text.each(function() {
var text = d3.select(this),
words = text.text().split(/\s+/).reverse(),
word,
line = [],
lineNumber = 0,
lineHeight = 1.1, // ems
y = text.attr("y"),
dy = parseFloat(text.attr("dy")),
tspan = text.text(null).append("tspan").attr("x", 0).attr("y", y).attr("dy", dy + "em");
while (word = words.pop()) {
line.push(word);
tspan.text(line.join(" "));
if (tspan.node().getComputedTextLength() > width) {
line.pop();
tspan.text(line.join(" "));
line = [word];
tspan = text.append("tspan").attr("x", 0).attr("y", y).attr("dy", ++lineNumber * lineHeight + dy + "em").text(word);
}
}
});
}
if you are already using jQuery in your build just do this:
$(yourObject).length
It works nicely for me on objects, and I already had jQuery as a dependancy.
If you are ok to do transformation, you may try this.
DocumentBuilderFactory domFact = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = domFact.newDocumentBuilder();
Document doc = builder.parse(st);
DOMSource domSource = new DOMSource(doc);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.transform(domSource, result);
System.out.println("XML IN String format is: \n" + writer.toString());
As in the opencv-doc you can get video feed from a camera which is connected to your computer by following code.
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
# Capture frame-by-frame
ret, frame = cap.read()
# Our operations on the frame come here
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
# Display the resulting frame
cv2.imshow('frame',gray)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
You can change cap = cv2.VideoCapture(0)
index from 0
to 1
to access the 2nd camera.
Tested in opencv-3.2.0
i think this can be as simple
let as assume that you are going to pass multiple parameters to you action as you read up there actions accept only two parameters context
and payload
which is your data you want to pass in action so let take an example
Setting up Action
instead of
actions: {
authenticate: ({ commit }, token, expiration) => commit('authenticate', token, expiration)
}
do
actions: {
authenticate: ({ commit }, {token, expiration}) => commit('authenticate', token, expiration)
}
Calling (dispatching) Action
instead of
this.$store.dispatch({
type: 'authenticate',
token: response.body.access_token,
expiration: response.body.expires_in + Date.now()
})
do
this.$store.dispatch('authenticate',{
token: response.body.access_token,
expiration: response.body.expires_in + Date.now()
})
hope this gonna help

"Failed to resolve version for org.apache.maven.archetypes:maven-archetype- webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype- webapp/maven-metadata.xml in local"
So all you need to do is download the maven-metadata.xml to your {HOME}.m2\repository
That's it.
Short solution:
var n = 1234567890;
String(n).replace(/(.)(?=(\d{3})+$)/g,'$1,')
// "1,234,567,890"
Use immediate children selector >
:
$('#tblOne > tbody > tr')
Description: Selects all direct child elements specified by "child" of elements specified by "parent".
And finally the most simple solution:
With alert confirmation:
<script type="text/javascript">
// Set timeout variables.
var timoutWarning = 3000; // Display warning in 1Mins.
var timoutNow = 4000; // Timeout in 2 mins.
var warningTimer;
var timeoutTimer;
// Start timers.
function StartTimers() {
warningTimer = setTimeout("IdleWarning()", timoutWarning);
timeoutTimer = setTimeout("IdleTimeout()", timoutNow);
}
// Reset timers.
function ResetTimers() {
clearTimeout(warningTimer);
clearTimeout(timeoutTimer);
StartTimers();
$("#timeout").dialog('close');
}
// Show idle timeout warning dialog.
function IdleWarning() {
var answer = confirm("Session About To Timeout\n\n You will be automatically logged out.\n Confirm to remain logged in.")
if (answer){
ResetTimers();
}
else{
IdleTimeout();
}
}
// Logout the user and auto reload or use this window.open('http://www.YourPageAdress.com', '_self'); to auto load a page.
function IdleTimeout() {
window.open(self.location,'_top');
}
</script>

I didn't have to change my prostgresql.conf file but, i did have to do the following based on my psql via command line was connecting and pgAdmin not connecting on RDS with AWS.
I did have my RDS set to Publicly Accessible. I made sure my ACL and security groups were wide open and still problem so, I did the following:
sudo find . -name *.conf
then sudo nano ./data/pg_hba.conf
then added to top of directives in pg_hba.conf file host all all 0.0.0.0/0 md5
and pgAdmin automatically logged me in.
This also worked in pg_hba.conf file
host all all md5
without any IP address and this also worked with my IP address host all all <myip>/32 md5
As a side note, my RDS was in my default VPC. I had an identical RDS instance in my non-default VPC with identical security group, ACL and security group settings to my default VPC and I could not get it to work. Not sure why but, that's for another day.
As discussed in the comments, this can be achieved by converting the entry into Date
format and extracting the year, for instance like this:
format(as.Date(df1$Date, format="%d/%m/%Y"),"%Y")
Does
$ git log -p
do what you need?
Check out the chapter on Git Log in the Git Community Book for more examples. (Or look at the the documentation.)
Update: As others (Jakub and Bombe) already pointed out: although the above works, git show is actually the command that is intended to do exactly what was asked for.
This example selects a new Range
of Cells
defined by the current cell to a cell 5 to the right.
Note that .Offset
takes arguments of Offset(row, columns)
and can be quite useful.
Sub testForStackOverflow()
Range(ActiveCell, ActiveCell.Offset(0, 5)).Copy
End Sub
This code works:
let str = "governance[string_i_want]";
let res = str.match(/[^governance\[](.*)[^\]]/g);
res will equal "string_i_want". However, in this example res is still an array, so do not treat res like a string.
By grouping the characters I do not want, using [^string], and matching on what is between the brackets, the code extracts the string I want!
You can try it out here: https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_match_regexp
Good luck.
Sort list of int descending you could just sort first and reverse
class Program
{
static void Main(string[] args)
{
List<int> myList = new List<int>();
myList.Add(38);
myList.Add(34);
myList.Add(35);
myList.Add(36);
myList.Add(37);
myList.Sort();
myList.Reverse();
myList.ForEach(Console.WriteLine);
}
}
Please try the following way.
<table>
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
<tr>
<td>February</td>
<td>$80</td>
</tr>
<tr>
<td colspan="2">Sum: $180</td>
</tr>
</table>
If you are using SPs and if the sps have multiple Select statements (within if conditions) all those selects needs to be handled with unique field names.
Use poll to get the first element, and add to add a new last element. That's it, no synchronization or anything else.
echo
produces a trailing newline character which is hashed too. Try:
/bin/echo -n foobar | sha256sum
Simple, here replace the "APP" by name of the app you want to launch.
export APP_HOME=/Applications/APP.app/Contents/MacOS
export PATH=$PATH:$APP_HOME
Thanks me later.
row from a database table
You can use DataColumn.Ordinal
to get the index of the column in the DataTable
. So if you need the next column as mentioned use Column.Ordinal + 1
:
row[row.Table.Columns["ColumnName"].Ordinal + 1] = someOtherValue;
The syntax is no longer supported in python 3. Use the following instead.
try:
do_something()
except BaseException as e:
logger.error('Failed to do something: ' + str(e))
You need to copy over the private key and certificate from your old Mac. Open Keychain Access on the old Mac and look in the Keys category of the login keychain: the key should be there. You need to export both the public and private key, then copy yourkey.pem
and yourkey.p12
to the new Mac.
Importing them using Keychain Access will probably fail, at least under 10.6; you can use these commands instead:
security import yourkey.p12
security import yourkey.pem
I had the same problem when trying to load Hadoop project in eclipse. I tried the solutions above, and I believe it might have worked in Eclipse Kepler... not even sure anymore (tried too many things).
With all the problems I was having, I decided to move on to Eclipse Luna, and the solutions above did not work for me.
There was another post that recommended changing the ... tag to package. I started doing that, and it would "clear" the errors... However, I start to think that the changes would bite me later - I am not an expert on Maven.
Fortunately, I found out how to remove all the errors. Go to Window->Preferences->Maven-> Error/Warnings and change "Plugin execution not covered by lifecycle..." option to "Ignore". Hope it helps.
Similar to Jeff's idea (untested):
find . -name * -print0 | grep -v "exclude" | xargs -0 -I {} cp -a {} destination/
You can sort a list in-place just by calling List<T>.Sort
:
list.Sort();
That will use the natural ordering of elements, which is fine in your case.
EDIT: Note that in your code, you'd need
_details.Sort();
as the Sort
method is only defined in List<T>
, not IList<T>
. If you need to sort it from the outside where you don't have access to it as a List<T>
(you shouldn't cast it as the List<T>
part is an implementation detail) you'll need to do a bit more work.
I don't know of any IList<T>
-based in-place sorts in .NET, which is slightly odd now I come to think of it. IList<T>
provides everything you'd need, so it could be written as an extension method. There are lots of quicksort implementations around if you want to use one of those.
If you don't care about a bit of inefficiency, you could always use:
public void Sort<T>(IList<T> list)
{
List<T> tmp = new List<T>(list);
tmp.Sort();
for (int i = 0; i < tmp.Count; i++)
{
list[i] = tmp[i];
}
}
In other words, copy, sort in place, then copy the sorted list back.
You can use LINQ to create a new list which contains the original values but sorted:
var sortedList = list.OrderBy(x => x).ToList();
It depends which behaviour you want. Note that your shuffle method isn't really ideal:
Random
within the method runs into some of the problems shown hereval
inside the loop - you're not using that default valueCount
property when you know you're working with an IList<T>
for
loop is simpler to understand than traversing the list backwards with a while
loopThere are other implementations of shuffling with Fisher-Yates on Stack Overflow - search and you'll find one pretty quickly.
Give this a try:
foreach (PropertyInfo propertyInfo in obj.GetType().GetProperties())
{
// do stuff here
}
Also please note that Type.GetProperties()
has an overload which accepts a set of binding flags so you can filter out properties on a different criteria like accessibility level, see MSDN for more details: Type.GetProperties Method (BindingFlags) Last but not least don't forget to add the "system.Reflection" assembly reference.
For instance to resolve all public properties:
foreach (var propertyInfo in obj.GetType()
.GetProperties(
BindingFlags.Public
| BindingFlags.Instance))
{
// do stuff here
}
Please let me know whether this works as expected.
"Hello! world!".TrimEnd('!');
EDIT:
What I've noticed in this type of questions that quite everyone suggest to remove the last char of given string. But this does not fulfill the definition of Trim method.
Trim - Removes all occurrences of white space characters from the beginning and end of this instance.
Under this definition removing only last character from string is bad solution.
So if we want to "Trim last character from string" we should do something like this
Example as extension method:
public static class MyExtensions
{
public static string TrimLastCharacter(this String str)
{
if(String.IsNullOrEmpty(str)){
return str;
} else {
return str.TrimEnd(str[str.Length - 1]);
}
}
}
Note if you want to remove all characters of the same value i.e(!!!!)the method above removes all existences of '!' from the end of the string, but if you want to remove only the last character you should use this :
else { return str.Remove(str.Length - 1); }
If you are using a navigation controller and just want to know if you are in the active and topmost controller, then use:
if navigationController?.topViewController == self {
// Do something
}
This answer is based on @mattdipasquale's comment.
If you have a more complicated scenario, see the other answers above.
C# supports two boolean or
operators: the single bar |
and the double-bar ||
.
The difference is that |
always checks both the left and right conditions, while ||
only checks the right-side condition if it's necessary (if the left side evaluates to false).
This is significant when the condition on the right-side involves processing or results in side effects. (For example, if your ErrorDumpWriter.Close
method took a while to complete or changed something's state.)
A better solution:
function getViewportSize(w) {
var w = w || window;
if(w.innerWidth != null)
return {w:w.innerWidth, h:w.innerHeight};
var d = w.document;
if (document.compatMode == "CSS1Compat") {
return {
w: d.documentElement.clientWidth,
h: d.documentElement.clientHeight
};
}
return { w: d.body.clientWidth, h: d.body.clientWidth };
}
function isViewportVisible(e) {
var box = e.getBoundingClientRect();
var height = box.height || (box.bottom - box.top);
var width = box.width || (box.right - box.left);
var viewport = getViewportSize();
if(!height || !width)
return false;
if(box.top > viewport.h || box.bottom < 0)
return false;
if(box.right < 0 || box.left > viewport.w)
return false;
return true;
}
UsedRange represents not only nonempty cells, but also formatted cells without any value. And that's why you should be very vigilant.
This example illustrate how to use AJAX to pull resourcess from any website. it works across browsers. i have tested it on IE8-IE10, safari, chrome, firefox, opera.
if (window.XDomainRequest) xmlhttp = new XDomainRequest();
else if (window.XMLHttpRequest) xmlhttp = new XMLHttpRequest();
else xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.open("GET", "http://api.hostip.info/get_html.php", false);
xmlhttp.send();
hostipInfo = xmlhttp.responseText.split("\n");
var IP = false;
for (i = 0; hostipInfo.length >= i; i++) {
if (hostipInfo[i]) {
ipAddress = hostipInfo[i].split(":");
if (ipAddress[0] == "IP") {
IP = ipAddress[1];
}
}
}
return IP;
