There are many quirks in the way browsers handle XMLHttpRequest, this JS code will work across all browsers:
https://github.com/ilinsky/xmlhttprequest
This JS code converts XML into easy to use JavaScript objects:

The JS code above can be included in the page to meet your no external library requirement.
var symbol = "MSFT";
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState == 4) {
alert(xmlhttp.responseText);
// http://www.terracoder.com convert XML to JSON
var json = XMLObjectifier.xmlToJSON(xmlhttp.responseXML);
var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
// Result text is escaped XML string, convert string to XML object then convert to JSON object
json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text);
}

I have reformatted your code.
The error was situated in this line :
printf("%d", (**c));
To fix it, change to :
printf("%d", (*c));
The * retrieves the value from an address. The ** retrieves the value (an address in this case) of an other value from an address.
In addition, the () was optional.
#include <stdio.h>
int main(void)
{
int b = 10;
int *a = NULL;
int *c = NULL;
a = &b;
c = &a;
printf("%d", *c);
return 0;
}
EDIT :
The line :
c = &a;
must be replaced by :
c = a;
It means that the value of the pointer 'c' equals the value of the pointer 'a'. So, 'c' and 'a' points to the same address ('b'). The output is :
10
EDIT 2:
If you want to use a double * :
#include <stdio.h>
int main(void)
{
int b = 10;
int *a = NULL;
int **c = NULL;
a = &b;
c = &a;
printf("%d", **c);
return 0;
}
Output:
10
I normally alias using built-in application launcher (open) from OS X:
alias pc='open -a /Applications/PyCharm\ CE.app'
Then I can type:
pc myfile1.txt myfiles*.py
Though you can't (easily) pass args to PyCharm, if you want a quick way to open files (without needing to use full pathnames to the file), this does the trick.
On mac and sublime text 3 , which version is 3103, the content should be

PDFBox is the best library I've found for this purpose, it's comprehensive and really quite easy to use if you're just doing basic text extraction. Examples can be found here.
It explains it on the page, but one thing to watch out for is that the start and end indexes when using setStartPage() and setEndPage() are both inclusive. I skipped over that explanation first time round and then it took me a while to realise why I was getting more than one page back with each call!
Itext is another alternative that also works with C#, though I've personally never used it. It's more low level than PDFBox, so less suited to the job if all you need is basic text extraction.
protected $primaryKey = 'SongID';
After adding to my model to tell the primary key because it was taking id(SongID) by default
you can try adding
$db['db_debug'] = FALSE;
in "your database file".php after that you can modify your database as you like.
when you need to send files through a specific SSH port:
rsync -azP -e "ssh -p PORT_NUMBER" source destination
example
rsync -azP -e "ssh -p 2121" /path/to/files/source user@remoteip:/path/to/files/destination
I think any style that breaks a language's own style guidelines (without due reason) is ugly and therefore "bad".
No doubt the code you've seen was written by someone who used to work on a language where underscores were acceptable.
Some people just cannot adapt to new coding styles...
$('input[type=file]').val()
That'll get you the file selected.
However, you can't set the value yourself.
Try to use setStyle() in onCreate and override onCreateDialog make dialog without title
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
return dialog;

or just override onCreate() and setStyle fellow the code.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme);
}
The problem with your attempt at the psql
command line is the direction of the slashes:
newTestDB-# /i E:\db-rbl-restore-20120511_Dump-20120514.sql # incorrect
newTestDB-# \i E:/db-rbl-restore-20120511_Dump-20120514.sql # correct
To be clear, psql
commands start with a backslash, so you should have put \i
instead. What happened as a result of your typo is that psql
ignored everything until finding the first \
, which happened to be followed by db
, and \db
happens to be the psql
command for listing table spaces, hence why the output was a List of tablespaces. It was not a listing of "default tables of PostgreSQL" as you said.
Further, it seems that psql
expects the filepath
argument to delimit directories using the forward slash regardless of OS (thus on Windows this would be counter-intuitive).
It is worth noting that your attempt at "elevating permissions" had no relation to the outcome of the command you attempted to execute. Also, you did not say what caused the supposed "Permission Denied" error.
Finally, the extension on the dump file does not matter, in fact you don't even need an extension. Indeed, pgAdmin
suggests a .backup
extension when selecting a backup filename, but you can actually make it whatever you want, again, including having no extension at all. The problem is that pgAdmin
seems to only allow a "Restore" of "Custom or tar" or "Directory" dumps (at least this is the case in the MAC OS X version of the app), so just use the psql
\i
command as shown above.
The Html.Hidden creates a hidden input but you have to specify the name and all the attributes you want to give that field and value. The Html.HiddenFor
creates a hidden input for the object that you pass to it, they look like this:
Html.Hidden("yourProperty",model.yourProperty);
Html.HiddenFor(m => m.yourProperty)
In this case the output is the same!

Follows an extract from Closure: The Definitive Guide by Michael Bolin. It might look a bit lengthy, but it's saturated with a lot of insight. From "Appendix B. Frequently Misunderstood JavaScript Concepts":
this
Refers to When a Function is CalledWhen calling a function of the form foo.bar.baz()
, the object foo.bar
is referred to as the receiver. When the function is called, it is the receiver that is used as the value for this
:
var obj = {};
obj.value = 10;
/** @param {...number} additionalValues */
obj.addValues = function(additionalValues) {
for (var i = 0; i < arguments.length; i++) {
this.value += arguments[i];
}
return this.value;
};
// Evaluates to 30 because obj is used as the value for 'this' when
// obj.addValues() is called, so obj.value becomes 10 + 20.
obj.addValues(20);
If there is no explicit receiver when a function is called, then the global object becomes the receiver. As explained in "goog.global" on page 47, window is the global object when JavaScript is executed in a web browser. This leads to some surprising behavior:
var f = obj.addValues;
// Evaluates to NaN because window is used as the value for 'this' when
// f() is called. Because and window.value is undefined, adding a number to
// it results in NaN.
f(20);
// This also has the unintentional side effect of adding a value to window:
alert(window.value); // Alerts NaN
Even though obj.addValues
and f
refer to the same function, they behave differently when called because the value of the receiver is different in each call. For this reason, when calling a function that refers to this
, it is important to ensure that this
will have the correct value when it is called. To be clear, if this
were not referenced in the function body, then the behavior of f(20)
and obj.addValues(20)
would be the same.
Because functions are first-class objects in JavaScript, they can have their own methods. All functions have the methods call()
and apply()
which make it possible to redefine the receiver (i.e., the object that this
refers to) when calling the function. The method signatures are as follows:
/**
* @param {*=} receiver to substitute for 'this'
* @param {...} parameters to use as arguments to the function
*/
Function.prototype.call;
/**
* @param {*=} receiver to substitute for 'this'
* @param {Array} parameters to use as arguments to the function
*/
Function.prototype.apply;
Note that the only difference between call()
and apply()
is that call()
receives the function parameters as individual arguments, whereas apply()
receives them as a single array:
// When f is called with obj as its receiver, it behaves the same as calling
// obj.addValues(). Both of the following increase obj.value by 60:
f.call(obj, 10, 20, 30);
f.apply(obj, [10, 20, 30]);
The following calls are equivalent, as f
and obj.addValues
refer to the same function:
obj.addValues.call(obj, 10, 20, 30);
obj.addValues.apply(obj, [10, 20, 30]);
However, since neither call()
nor apply()
uses the value of its own receiver to substitute for the receiver argument when it is unspecified, the following will not work:
// Both statements evaluate to NaN
obj.addValues.call(undefined, 10, 20, 30);
obj.addValues.apply(undefined, [10, 20, 30]);
The value of this
can never be null
or undefined
when a function is called. When null
or undefined
is supplied as the receiver to call()
or apply()
, the global object is used as the value for receiver instead. Therefore, the previous code has the same undesirable side effect of adding a property named value
to the global object.
It may be helpful to think of a function as having no knowledge of the variable to which it is assigned. This helps reinforce the idea that the value of this will be bound when the function is called rather than when it is defined.

You will need wrapper classes:
public class SomeIntInfo
{
[XmlAttribute]
public int Value { get; set; }
}
public class SomeStringInfo
{
[XmlAttribute]
public string Value { get; set; }
}
public class SomeModel
{
[XmlElement("SomeStringElementName")]
public SomeStringInfo SomeString { get; set; }
[XmlElement("SomeInfoElementName")]
public SomeIntInfo SomeInfo { get; set; }
}
or a more generic approach if you prefer:
public class SomeInfo<T>
{
[XmlAttribute]
public T Value { get; set; }
}
public class SomeModel
{
[XmlElement("SomeStringElementName")]
public SomeInfo<string> SomeString { get; set; }
[XmlElement("SomeInfoElementName")]
public SomeInfo<int> SomeInfo { get; set; }
}
And then:
class Program
{
static void Main()
{
var model = new SomeModel
{
SomeString = new SomeInfo<string> { Value = "testData" },
SomeInfo = new SomeInfo<int> { Value = 5 }
};
var serializer = new XmlSerializer(model.GetType());
serializer.Serialize(Console.Out, model);
}
}
will produce:

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.
ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.
The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).
A better option
Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE
). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses
(and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.
You can use this code to Download file from a WebSite to Desktop:

In laymen's terms an unsigned int is an integer that can not be negative and thus has a higher range of positive values that it can assume. A signed int is an integer that can be negative but has a lower positive range in exchange for more negative values it can assume.
Its not working because col-xs-offset-*
is mentioned out of the media query. if you want to use it, you have to mention all the offset (eg: class="col-xs-offset-3 col-sm-offset-2 col-md-offset-1 col-lg-offset-0"
)
But this is not right, they should mention col-xs-offset-*
in the media query
If you are running OSX, then the easiest way to produce a true system process is to use launchd
to launch it.
Build a plist like this, and put it into the /Library/LaunchDaemons with the name top-level-domain.your-domain.application.plist
(you need to be root when placing it):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>top-level-domain.your-domain.application</string>
<key>WorkingDirectory</key>
<string>/your/preferred/workingdirectory</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/bin/node</string>
<string>your-script-file</string>
</array>
<key>RunAtLoad</key>
<true/>
<key>KeepAlive</key>
<true/>
</dict>
</plist>
When done, issue this (as root):
launchctl load /Library/LaunchDaemons/top-level-domain.your-domain.application.plist
launchctl start top-level-domain.your-domain.application
and you are running.
And you will still be running after a restart.
For other options in the plist look at the man page here: https://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man5/launchd.plist.5.html
Here's my suggested approach. It's not completely satisfactory (I'm very new to Swift and OOP!) but maybe someone can refine it. The idea is to have each enum provide its own range information as .first
and .last
properties. It adds just two lines of code to each enum: still a bit hard-coded, but at least it's not duplicating the whole set. It does require modifying the Suit
enum to be an Int like the Rank
enum is, instead of untyped.
Rather than echo the whole solution, here's the code I added to the .
enum, somewhere after the case statements (Suit
enum is similar):
var first: Int { return Ace.toRaw() }
var last: Int { return King.toRaw() }
and the loop I used to build the deck as an array of String. (The problem definition did not state how the deck was to be structured.)
func createDeck() -> [String] {
var deck: [String] = []
var card: String
for r in Rank.Ace.first...Rank.Ace.last {
for s in Suit.Hearts.first...Suit.Hearts.last {
card = Rank.simpleDescription( Rank.fromRaw(r)!)() + " of " + Suit.simpleDescription( Suit.fromRaw(s)!)()
deck.append( card)
}
}
return deck
}
It's unsatisfactory because the properties are associated to an element rather than to the enum. But it does add clarity to the 'for' loops. I'd like it to say Rank.first
instead of Rank.Ace.first
. It works (with any element), but it's ugly. Can someone show how to elevate that to the enum level?
And to make it work, I lifted the createDeck
method out of the Card struct. I could not figure out how to get a [String] array returned from that struct, and that seems a bad place to put such a method anyway.
No offence, but none of the other answers (so far) has it quite right.
break
is used to immediately terminate a for
loop, a while
loop or a switch
statement. You can not break
from an if
block.
return
is used the terminate a method (and possibly return a value).
A return
within any loop or block will of course also immediately terminate that loop/block.
There's something overly verbose to me about the if ((x & y) == y)...
construct, especially if x
AND y
are both compound sets of flags and you only want to know if there's any overlap.
In this case, all you really need to know is if there's a non-zero value[1] after you've bitmasked.
[1] See Jaime's comment. If we were authentically bitmasking, we'd only need to check that the result was positive. But since
enum
s can be negative, even, strangely, when combined with the[Flags]
attribute, it's defensive to code for!= 0
rather than> 0
.

The reverse() is used to adhere the django DRY principle i.e if you change the url in future then you can reference that url using reverse(urlname).

In the OnLoad event for your Main form show the Logon form as a dialog. If the dialog result of that is OK then allow Main to continue loading, if the result is authentication failure then abort the load and show the message box.
EDIT Code sample(s)
private void MainForm_Load(object sender, EventArgs e)
{
this.Hide();
LogonForm logon = new LogonForm();
if (logon.ShowDialog() != DialogResult.OK)
{
//Handle authentication failures as necessary, for example:
Application.Exit();
}
else
{
this.Show();
}
}
Another solution would be to show the LogonForm from the Main method in program.cs, something like this:
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
LogonForm logon = new LogonForm();
Application.Run(logon);
if (logon.LogonSuccessful)
{
Application.Run(new MainForm());
}
}
In this example your LogonForm would have to expose out a LogonSuccessful bool property that is set to true when the user has entered valid credentials
check if a user exists or not. If not insert
$exist = DB::table('User')->where(['username'=>$username,'password'=>$password])->get();
if(count($exist) >0) {
echo "User already exist";;
}
else {
$data=array('username'=>$username,'password'=>$password);
DB::table('User')->insert($data);
}

Ian Kemp has the answer (have some points btw..), this is to simply add some meat to one of his steps.
The reason I ended up here was that dev's machines were building fine, but the build server simply wasn't pulling down the packages required (empty packages folder) and therefore the build was failing. Logging onto the build server and manually building the solution worked, however.
To fulfil the second of Ians 3 point steps (running nuget restore), you can create an MSBuild target running the exec command to run the nuget restore command, as below (in this case nuget.exe is in the .nuget folder, rather than on the path), which can then be run in a TeamCity build step (other CI available...) immediately prior to building the solution
<Target Name="BeforeBuild">
<Exec Command="..\.nuget\nuget restore ..\MySolution.sln"/>
</Target>
For the record I'd already tried the "nuget installer" runner type but this step was hanging on web projects (worked for DLL's and Windows projects)
Other solutions on this page aren't desirable if you have a long list of extensions -- maintaining a long sequence of -not -name 'this' -not -name 'that' -not -name 'other'
would be tedious and error-prone -- or if the search is programmatic and the list of extensions is built at runtime.
For those situations, a solution that more clearly separates data (the list of extensions) and code (the parameters to find
) may be desirable. Given a directory & file structure that looks like this:
.
+-- a
+-- 1.txt
+-- 15.xml
+-- 8.dll
+-- b
¦ +-- 16.xml
¦ +-- 2.txt
¦ +-- 9.dll
¦ +-- c
¦ +-- 10.dll
¦ +-- 17.xml
¦ +-- 3.txt
+-- d
¦ +-- 11.dll
¦ +-- 18.xml
¦ +-- 4.txt
¦ +-- e
¦ +-- 12.dll
¦ +-- 19.xml
¦ +-- 5.txt
+-- f
+-- 13.dll
+-- 20.xml
+-- 6.txt
+-- g
+-- 14.dll
+-- 21.xml
+-- 7.txt
You can do something like this:
## data section, list undesired extensions here
declare -a _BADEXT=(xml dll)
## code section, this never changes
BADEXT="$( IFS="|" ; echo "${_BADEXT[*]}" | sed 's/|/\\|/g' )"
find . -type f ! -regex ".*\.\($BADEXT\)"
Which results in:
./a/1.txt
./a/b/2.txt
./a/b/c/3.txt
./a/d/4.txt
./a/d/e/5.txt
./a/f/6.txt
./a/f/g/7.txt
You can change the extensions list without changing the code block.

Use the System.Environment class.
The methods
var value = System.Environment.GetEnvironmentVariable(variable [, Target])

System.Environment.SetEnvironmentVariable(variable, value [, Target])

The optional parameter Target
is an enum of type EnvironmentVariableTarget
and it can be one of: Machine
, Process
, or User
. If you omit it, the default target is the current process.
See .offset()
here in the jQuery doc. It gives the position relative to the document, not to the parent. You perhaps have .offset()
and .position()
confused. If you want the position in the window instead of the position in the document, you can subtract off the .scrollTop()
and .scrollLeft()
values to account for the scrolled position.
Here's an excerpt from the doc:
The .offset() method allows us to retrieve the current position of an element relative to the document. Contrast this with .position(), which retrieves the current position relative to the offset parent. When positioning a new element on top of an existing one for global manipulation (in particular, for implementing drag-and-drop), .offset() is the more useful.
To combine these:
var offset = $("selector").offset();
var posY = offset.top - $(window).scrollTop();
var posX = offset.left - $(window).scrollLeft();
You can try it here (scroll to see the numbers change): http://jsfiddle.net/jfriend00/hxRPQ/
If you don't want to create another migration-file for a small, recent change - from Rails Console:
ActiveRecord::Migration.change_column :profiles, :show_attribute, :boolean, :default => true
Then exit and re-enter rails console, so DB-Changes will be in-effect. Then, if you do this ...
Profile.new()
You should see the "show_attribute" default-value as true.
For existing records, if you want to preserve existing "false" settings and only update "nil" values to your new default:
Profile.all.each{|profile| profile.update_attributes(:show_attribute => (profile.show_attribute == nil ? true : false)) }
Update the migration that created this table, so any future builds of the DB will get it right from the onset. Also run the same process on any deployed-instances of the DB.
If using the "new db migration" method, you can do the update of existing nil-values in that migration.

A good reason, which you have sort of touched on, is that once the CSRF cookie has been received, it is then available for use throughout the application in client script for use in both regular forms and AJAX POSTs. This will make sense in a JavaScript heavy application such as one employed by AngularJS (using AngularJS doesn't require that the application will be a single page app, so it would be useful where state needs to flow between different page requests where the CSRF value cannot normally persist in the browser).
Consider the following scenarios and processes in a typical application for some pros and cons of each approach you describe. These are based on the Synchronizer Token Pattern.

So the cookie approach is fairly dynamic offering an easy way to retrieve the cookie value (any HTTP request) and to use it (JS can add the value to any form automatically and it can be employed in AJAX requests either as a header or as a form value). Once the CSRF token has been received for the session, there is no need to regenerate it as an attacker employing a CSRF exploit has no method of retrieving this token. If a malicious user tries to read the user's CSRF token in any of the above methods then this will be prevented by the Same Origin Policy. If a malicious user tries to retrieve the CSRF token server side (e.g. via curl
) then this token will not be associated to the same user account as the victim's auth session cookie will be missing from the request (it would be the attacker's - therefore it won't be associated server side with the victim's session).
As well as the Synchronizer Token Pattern there is also the Double Submit Cookie CSRF prevention method, which of course uses cookies to store a type of CSRF token. This is easier to implement as it does not require any server side state for the CSRF token. The CSRF token in fact could be the standard authentication cookie when using this method, and this value is submitted via cookies as usual with the request, but the value is also repeated in either a hidden field or header, of which an attacker cannot replicate as they cannot read the value in the first place. It would be recommended to choose another cookie however, other than the authentication cookie so that the authentication cookie can be secured by being marked HttpOnly. So this is another common reason why you'd find CSRF prevention using a cookie based method.
GitHub pages host only static HTML pages. No server side technology is supported, so Node.js applications won't run on GitHub pages. There are lots of hosting providers, as listed on the Node.js wiki.
App fog seems to be the most economical as it provides free hosting for projects with 2GB of RAM (which is pretty good if you ask me).
As stated here, AppFog removed their free plan for new users.
If you want to host static pages on GitHub, then read this guide. If you plan on using Jekyll, then this guide will be very helpful.
My ~/.gradle/caches/
folder was using 14G.
After using the following solution, it went from 14G to 1.7G.
$ rm -rf ~/.gradle/caches/transforms-*
$ rm -rf ~/.gradle/caches/build-cache-*
Bonus
This command shows you in detail the used cache space
$ sudo du -ah --max-depth = 1 ~/.gradle/caches/ | sort -hr
Yes, here's an example:
CREATE TABLE myTable ( col1 int, createdDate datetime DEFAULT(getdate()), updatedDate datetime DEFAULT(getdate()) )
You can INSERT into the table without indicating the createdDate and updatedDate columns:
INSERT INTO myTable (col1) VALUES (1)
Or use the keyword DEFAULT:
INSERT INTO myTable (col1, createdDate, updatedDate) VALUES (1, DEFAULT, DEFAULT)
Then create a trigger for updating the updatedDate column:
CREATE TRIGGER dbo.updateMyTable
ON dbo.myTable
FOR UPDATE
AS
BEGIN
IF NOT UPDATE(updatedDate)
UPDATE dbo.myTable SET updatedDate=GETDATE()
WHERE col1 IN (SELECT col1 FROM inserted)
END
GO
Further to everyone else's answer, you should note that the parameters are optional in C# if your application does not use command line arguments.
This code is perfectly valid:
internal static Program
{
private static void Main()
{
// Get on with it, without any arguments...
}
}
If you need or want a simple HTTP server with the following:
I built one on top of the excellent SimpleHTTPAuthServer already on PyPI. This adds handling of POST requests: https://github.com/arielampol/SimpleHTTPAuthServerWithPOST
Otherwise, all the other options publicly available are already so good and robust.
The script tag to the api has changed recently. Use something like this to query the Geocoding API and get the JSON object back
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/geocode/json?address=THE_ADDRESS_YOU_WANT_TO_GEOCODE&key=YOUR_API_KEY"></script>
The address could be something like
1600+Amphitheatre+Parkway,+Mountain+View,+CA (URI Encoded; you should Google it. Very useful)
or simply
1600 Amphitheatre Parkway, Mountain View, CA
By entering this address https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY
inside the browser, along with my API Key, I get back a JSON object which contains the Latitude & Longitude for the city of Moutain view, CA.

Web Frameworks such like AngularJS allow us to perform these queries with ease.
Fixed positioning will do what you need:
#main
{
position:fixed;
top:0px;
bottom:0px;
left:0px;
right:0px;
}
Step 1: Simply put all the required code in a "MAIN.BAT" file.
Step 2: Create another bat file, say MainCaller.bat, and just copy/paste these 3 lines of code:
REM THE MAIN FILE WILL BE CALLED FROM HERE..........
CD "File_Path_Where_Main.bat_is_located"
MAIN.BAT > log.txt
Step 3: Just double click "MainCaller.bat".
All the output will be logged into the text file named "log".
You can try this if you are passing a value to the action method.
@Html.DropDownList("Sortby", new SelectListItem[] { new SelectListItem() { Text = "Newest to Oldest", Value = "0" }, new SelectListItem() { Text = "Oldest to Newest", Value = "1" }},new { onchange = "document.location.href = '/ControllerName/ActionName?id=' + this.options[this.selectedIndex].value;" })
Remove the query string in case of no parameter passing.
There is a nice form plugin that allows you to send an HTML form asynchroniously.
$(document).ready(function() {
$('#myForm1').ajaxForm();
});
or
$("select").change(function(){
$('#myForm1').ajaxSubmit();
});
to submit the form immediately
Consider a right angled triangle. We label the hypotenuse r, the horizontal side y and the vertical side x. The angle of interest α is the angle between x and r.
C++ atan2(y, x)
will give us the value of angle α in radians.
atan
is used if we only know or are interested in y/x not y and x individually. So if p = y/x
then to get α we'd use atan(p)
.
You cannot use atan2
to determine the quadrant, you can use atan2
only if you already know which quadrant your in! In particular positive x and y imply the first quadrant, positive y and negative x, the second and so on. atan
or atan2
themselves simply return a positive or a negative number, nothing more.
use js:
$(document).ready(function ()
{ $(".class-span").each(function(i){
var len=$(this).text().trim().length;
if(len>100)
{
$(this).text($(this).text().substr(0,100)+'...');
}
});
});
As in the answer of Escobar Ceaser, I suggest to use quotes arround the whole path. It's the common way to wrap the whole path in "", not only separate directory names within the path.
I had a similar issue that it didn't work for me. But it was no option to use "" within the path for separate directory names because the path contained environment variables, which theirself cover more than one directory hierarchies. The conclusion was that I missed the space between the closing " and the (
The correct version, with the space before the bracket, would be
If NOT exist "C:\Documents and Settings\John\Start Menu\Programs\Software Folder" (
start "\\filer\repo\lab\software\myapp\setup.exe"
pause
)
if you do ctrl-z
and then type exit
it will close background applications.
Ctrl+Q
is another good way to kill the application.
It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.
Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.
DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj
...
The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.
var DyObjectsList = new List<dynamic>;
if (condition1) {
dynamic DyObj = new ExpandoObject();
DyObj.Required = true;
DyObj.Message = "Message 1";
DyObjectsList .Add(DyObj);
}
if (condition2) {
dynamic DyObj = new ExpandoObject();
DyObj.Required = false;
DyObj.Message = "Message 2";
DyObjectsList .Add(DyObj);
}
your resulting List essentially looks like this
DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj
Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.
However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.
Variable that is not defined will cause compilation error.
What you're asking is about checking if it is initialized. But initialization is just a value, that you should choose and assign in the constructor.
For example:
class MyClass
{
MyClass() : mCharacter('0'), mDecimal(-1.0){};
void SomeMethod();
char mCharacter;
double mDecimal;
};
void MyClass::SomeMethod()
{
if ( mCharacter != '0')
{
// touched after the constructor
// do something with mCharacter.
}
if ( mDecimal != -1.0 )
{
// touched after the constructor
// define mDecimal.
}
}
You should initialize to a default value that will mean something in the context of your logic, of course.

file()
is not supported in Python 3
Use open()
instead; see Built-in Functions - open().
First, check git status
.
As the OP mentions,
The actual issue was an unresolved merge conflict from the merge, NOT that the stash would cause a merge conflict.
That is where git status
would mention that file as being "both modified
"
Resolution: Commit the conflicted file.
You can find a similar situation 4 days ago at the time of writing this answer (March 13th, 2012) with this post: "‘Pull is not possible because you have unmerged files’":
julita@yulys:~/GNOME/baobab/help/C$ git stash pop
help/C/scan-remote.page: needs merge
unable to refresh index
What you did was to fix the merge conflict (editing the right file, and committing it):
See "How do I fix merge conflicts in Git?"
What the blog post's author did was:
julita@yulys:~/GNOME/baobab/help/C$ git reset --hard origin/mallard-documentation
HEAD is now at ff2e1e2 Add more steps for optional information for scanning.
I.e aborting the current merge completely, allowing the git stash pop
to be applied.
See "Aborting a merge in Git".
Those are your two options.

PHP by itself has no SMS module or functions and doesn't allow you to send SMS.
SMS ( Short Messaging System) is a GSM technology an you need a GSM provider that will provide this service for you and may have an PHP API implementation for it.
Usually people in telecom business use Asterisk to handle calls and sms programming.
I would recommend checking out Gabor Grothendieck's sqldf package, which allows you to express these operations in SQL.
library(sqldf)
## inner join
df3 <- sqldf("SELECT CustomerId, Product, State
FROM df1
JOIN df2 USING(CustomerID)")
## left join (substitute 'right' for right join)
df4 <- sqldf("SELECT CustomerId, Product, State
FROM df1
LEFT JOIN df2 USING(CustomerID)")
I find the SQL syntax to be simpler and more natural than its R equivalent (but this may just reflect my RDBMS bias).
See Gabor's sqldf GitHub for more information on joins.
In Loops, I always prefer to use the Cells
class, using the R1C1 reference method, like this:
Cells(rr, col).Formula = ...
This allows me to quickly and easily loop over a Range of cells easily:
Dim r As Long
Dim c As Long
c = GetTargetColumn() ' Or you could just set this manually, like: c = 1
With Sheet1 ' <-- You should always qualify a range with a sheet!
For r = 1 To 10 ' Or 1 To (Ubound(MyListOfStuff) + 1)
' Here we're looping over all the cells in rows 1 to 10, in Column "c"
.Cells(r, c).Value = MyListOfStuff(r)
'---- or ----
'...to easily copy from one place to another (even with an offset of rows and columns)
.Cells(r, c).Value = Sheet2.Cells(r + 3, 17).Value
Next r
End With
another way to solve this: preg_match('/^\d+\.\d+$/',$number);
:)
You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.
The data and the error are available directly via these callbacks.
The library is called angular-extended-http-client.
angular-extended-http-client library on GitHub
angular-extended-http-client library on NPM
Very easy to use.
In the traditional approach you return Observable<HttpResponse<
T>
> from Service API. This is tied to HttpResponse.
With this approach you have to use .subscribe(x => ...) in the rest of your code.
This creates a tight coupling between the http layer and the rest of your code.
You only deal with your Models in these strongly-typed callbacks.
Hence, The rest of your code only knows about your Models.
The strongly-typed callbacks are
Success:
T
>T
>Failure:
TError
>TError
>import { HttpClientExtModule } from 'angular-extended-http-client';
and in the @NgModule imports
imports: [
.
.
.
HttpClientExtModule
],
export class SearchModel {
code: string;
}
//Normal response returned by the API.
export class RacingResponse {
result: RacingItem[];
}
//Custom exception thrown by the API.
export class APIException {
className: string;
}
In your Service, you just create params with these callback types.
Then, pass them on to the HttpClientExt's get method.
import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.
@Injectable()
export class RacingService {
//Inject HttpClientExt component.
constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {
}
//Declare params of type IObservable<T> and IObservableError<TError>.
//These are the success and failure callbacks.
//The success callback will return the response objects returned by the underlying HttpClient call.
//The failure callback will return the error objects returned by the underlying HttpClient call.
searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
let url = this.config.apiEndpoint;
this.client.post<SearchModel, RacingResponse>(url, model,
ResponseType.IObservable, success,
ErrorType.IObservableError, failure);
}
}
In your Component, your Service is injected and the searchRaceInfo API called as shown below.
search() {
this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
error => this.errorMsg = error.className);
}
Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.
There is no literal difference between an id and name.
name is identifier and is used in http request sent by browser to server as a variable name associated with data contained in the value attribute of element.
The id on the other hand is a unique identifier for browser, client side and JavaScript.Hence form needs an id while its elements need a name.
id is more specifically used in adding attributes to unique elements.In DOM methods,Id is used in Javascript for referencing the specific element you want your action to take place on.
For example:
<html>
<body>
<h1 id="demo"></h1>
<script>
document.getElementById("demo").innerHTML = "Hello World!";
</script>
</body>
</html>
Same can be achieved by name attribute, but it's preferred to use id in form and name for small form elements like the input tag or select tag.
Ok. As the other answerers explained, a stack is a last-in, first-out data structure. You add an element to the top of the stack with a Push operation. You take an element off the top with a Pop operation. The elements are removed in reverse order to the order they were put inserted (hence Last In, First Out). For example, if you push the elments 1,2,3 in that order, the number 3 will be at the top of the stack. A Pop operation will remove it (it was the last in) and leave 2 at the top of the stack.
Regarding the rest of the lecture, the lecturer tried to describe a stack-based machine that evaluates arithmetic expressions. The machine operates by continuously popping 3 elements from the top of the stack. The first two elements are operands and the third is an operator (+, -, *, /). It then applies this operator on the operands, and pushes the result onto the stack. The process continues until there is only one element on the stack, which is the value of the expression.
So, suppose we begin by pushing the values "+/*23-21*5-41" in left-to-right order onto the stack. We then pop 3 elements from the top. The last in is first out, which means the first 3 element are "1", "4", and "-" in that order. We push the number 3 (the result of 4-1) onto the stack, then pop the three topmost elements: 3, 5, *. Push the result, 15, onto the stack, and so on.
You need to keep an array of the google.maps.Marker
objects to hide (or remove or run other operations on them).
In the global scope:
var gmarkers = [];
Then push the markers on that array as you create them:
var marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i].latitude, locations[i].longitude),
title: locations[i].title,
icon: icon,
map:map
});
// Push your newly created marker into the array:
gmarkers.push(marker);
Then to remove them:
function removeMarkers(){
for(i=0; i<gmarkers.length; i++){
gmarkers[i].setMap(null);
}
}

You can pass multiple parameters as "?param1=value1¶m2=value2
"
But it's not secure. It's vulnerable to Cross Site Scripting (XSS) Attack
.
Your parameter can be simply replaced with a script.
Have a look at this article and article
You can make it secure by using API of StringEscapeUtils
static String escapeHtml(String str)
Escapes the characters in a String using HTML entities.
Even using https
url for security without above precautions is not a good practice.
Have a look at related SE question:
By default, the post request has maximum size of 8mb. But you can modify it according to your requirements. The modification can be done by opening php.ini file (php configuration setting).
Find
post_max_size=8M //for me, that was on line:771
replace 8 according to your requirements.
All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if
to bind them all together in the way I believe you intend.
Just use the array of options, to see, which option is currently selected.
$options = array( 'one', 'two', 'three' );
$output = '';
for( $i=0; $i<count($options); $i++ ) {
$output .= '<option '
. ( $_GET['sel'] == $options[$i] ? 'selected="selected"' : '' ) . '>'
. $options[$i]
. '</option>';
}
Sidenote: I would define a value to be some kind of id for each element, else you may run into problems, when two options have the same string representation.

Not only is it the preferred way, it's the only reasonable way. Because strings are immutable, in order to "remove" a char from a string you have to create a new string whenever you want a different string value.
You may be wondering why strings are immutable, given that you have to make a whole new string every time you change a character. After all, C strings are just arrays of characters and are thus mutable, and some languages that support strings more cleanly than C allow mutable strings as well. There are two reasons to have immutable strings: security/safety and performance.
Security is probably the most important reason for strings to be immutable. When strings are immutable, you can't pass a string into some library and then have that string change from under your feet when you don't expect it. You may wonder which library would change string parameters, but if you're shipping code to clients you can't control their versions of the standard library, and malicious clients may change out their standard libraries in order to break your program and find out more about its internals. Immutable objects are also easier to reason about, which is really important when you try to prove that your system is secure against particular threats. This ease of reasoning is especially important for thread safety, since immutable objects are automatically thread-safe.
Performance is surprisingly often better for immutable strings. Whenever you take a slice of a string, the Python runtime only places a view over the original string, so there is no new string allocation. Since strings are immutable, you get copy semantics without actually copying, which is a real performance win.
Eric Lippert explains more about the rationale behind immutable of strings (in C#, not Python) here.
To modify DSM's answer a bit, get_loc
has some weird properties depending on the type of index in the current version of Pandas (1.1.5) so depending on your Index type you might get back an index, a mask, or a slice. This is somewhat frustrating for me because I don't want to modify the entire columns just to extract one variable's index. Much simpler is to avoid the function altogether:
list(df.columns).index('pear')
Very straightforward and probably fairly quick.
try this instead $(".video-divs.focused")
. This works if you are looking for video-divs that are focused.
You can use the library SectionedRecyclerViewAdapter to group your items in sections and add a header to each section, like on the image below:
First you create your section class:
class MySection extends StatelessSection {
String title;
List<String> list;
public MySection(String title, List<String> list) {
// call constructor with layout resources for this Section header, footer and items
super(R.layout.section_header, R.layout.section_item);
this.title = title;
this.list = list;
}
@Override
public int getContentItemsTotal() {
return list.size(); // number of items of this section
}
@Override
public RecyclerView.ViewHolder getItemViewHolder(View view) {
// return a custom instance of ViewHolder for the items of this section
return new MyItemViewHolder(view);
}
@Override
public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
MyItemViewHolder itemHolder = (MyItemViewHolder) holder;
// bind your view here
itemHolder.tvItem.setText(list.get(position));
}
@Override
public RecyclerView.ViewHolder getHeaderViewHolder(View view) {
return new SimpleHeaderViewHolder(view);
}
@Override
public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) {
MyHeaderViewHolder headerHolder = (MyHeaderViewHolder) holder;
// bind your header view here
headerHolder.tvItem.setText(title);
}
}
Then you set up the RecyclerView with your sections and change the SpanSize of the headers with a GridLayoutManager:
// Create an instance of SectionedRecyclerViewAdapter
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();
// Create your sections with the list of data
MySection section1 = new MySection("My Section 1 title", dataList1);
MySection section2 = new MySection("My Section 2 title", dataList2);
// Add your Sections to the adapter
sectionAdapter.addSection(section1);
sectionAdapter.addSection(section2);
// Set up a GridLayoutManager to change the SpanSize of the header
GridLayoutManager glm = new GridLayoutManager(getContext(), 2);
glm.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
@Override
public int getSpanSize(int position) {
switch(sectionAdapter.getSectionItemViewType(position)) {
case SectionedRecyclerViewAdapter.VIEW_TYPE_HEADER:
return 2;
default:
return 1;
}
}
});
// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(glm);
recyclerView.setAdapter(sectionAdapter);
The .btn-lg
class has the following CSS in Bootstrap 3 (link):
.btn-lg {
padding: 10px 16px;
font-size: 18px;
line-height: 1.33;
border-radius: 6px;
}
If you apply the same font-size
and line-height
to your span (either .glyphicon-link
or a newly created .glyphicons-lg
if you're going to use this effect in more than one instance), you'll get a Glyphicon the same size as the large button.
I had the same problem in Safari and Chrome (the only ones I've tested) but I just did something that seems to work, at least I haven't been able to reproduce the problem since I added the solution. What I did was add a metatag to the header with a generated timstamp. Doesn't seem right but it's simple :)
<meta name="304workaround" content="2013-10-24 21:17:23">
Update P.S As far as I can tell, the problem disappears when I remove my node proxy (by proxy i mean both express.vhost and http-proxy module), which is weird...
ActiveRecord#where will return an ActiveRecord::Relation object (which will never be nil). Try using .empty? on the relation to test if it will return any records.
tempData.push( data[index] );
I agree with the correct answer above, but.... your still not giving the index value for the data that you want to add to tempData. Without the [index] value the whole array will be added.
Another option is the static String.valueOf
method.
String.valueOf(i)
It feels slightly more right than Integer.toString(i)
to me. When the type of i changes, for example from int
to double
, the code will stay correct.
On Android, colors are can be specified as RGB or ARGB.
http://en.wikipedia.org/wiki/ARGB
In RGB you have two characters for every color (red, green, blue), and in ARGB you have two additional chars for the alpha channel.
So, if you have 8 characters, it's ARGB, with the first two characters specifying the alpha channel. If you remove the leading two characters it's only RGB (solid colors, no alpha/transparency). If you want to specify a color in your Java source code, you have to use:
int Color.argb (int alpha, int red, int green, int blue)
alpha Alpha component [0..255] of the color
red Red component [0..255] of the color
green Green component [0..255] of the color
blue Blue component [0..255] of the color
Reference: argb
You can keep primitive type by setting default value, in the your case just add "required = false" property:
@RequestParam(value = "i", required = false, defaultValue = "10") int i
P.S. This page from Spring documentation might be useful: Annotation Type RequestParam
Here is a simple way to loop any number of times in PowerShell.
It is the same as the for
loop above, but much easier to understand for newer programmers and scripters. It uses a range, and foreach. A range is defined as:
range = lower..upper
or
$range = 1..10
A range can be used directly in a for
loop as well, although not the most optimal approach, any performance loss or additional instruction to process would be unnoticeable. The solution is below:
foreach($i in 1..10){
Write-Host $i
}
Or in your case:
$ActiveCampaigns = 10
foreach($i in 1..$ActiveCampaigns)
{
Write-Host $i
If($i==$ActiveCampaigns){
// Do your stuff on the last iteration here
}
}
If you want just a first selected row, you can:
select fname from MyTbl where rownum = 1
You can also use analytic functions to order and take the top x:
select max(fname) over (rank() order by some_factor) from MyTbl

mysqladmin -u [username] -p password
worked for me on OS X El Capitan and MySQL 5.7.12 Community Server. Example:
$ /usr/local/mysql/bin/mysqladmin -u root -p password
Enter password:
New password:
Confirm new password:
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
This is similar to pavan sachi's answer, but with password prompts.
My error was "#1862 - Your password has expired. To log in you must change it using a client that supports expired passwords." at phpMyAdmin login screen first time.
It's working better. Try it.

Linux does not have any system variables that give the current CPU utilization. Instead, you have to read /proc/stat
several times: each column in the cpu(n)
lines gives the total CPU time, and you have to take subsequent readings of it to get percentages. See this document to find out what the various columns mean.
I've just managed to setup new TabLayout, so here are the quick steps to do this (????)?*:???
Add dependencies inside your build.gradle file:
dependencies {
compile 'com.android.support:design:23.1.1'
}
Add TabLayout inside your layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"/>
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Setup your Activity like this:
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
public class TabLayoutActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pull_to_refresh);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
tabLayout.setupWithViewPager(viewPager);
}
public class SectionPagerAdapter extends FragmentPagerAdapter {
public SectionPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new FirstTabFragment();
case 1:
default:
return new SecondTabFragment();
}
}
@Override
public int getCount() {
return 2;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "First Tab";
case 1:
default:
return "Second Tab";
}
}
}
}
Another recursive solution, that works for arrays/lists and objects, or a mixture of both:
function deepSearchByKey(object, originalKey, matches = []) {
if(object != null) {
if(Array.isArray(object)) {
for(let arrayItem of object) {
deepSearchByKey(arrayItem, originalKey, matches);
}
} else if(typeof object == 'object') {
for(let key of Object.keys(object)) {
if(key == originalKey) {
matches.push(object);
} else {
deepSearchByKey(object[key], originalKey, matches);
}
}
}
}
return matches;
}
usage:
let result = deepSearchByKey(arrayOrObject, 'key'); // returns an array with the objects containing the key
Your second way is correct.
def foo(opts: dict = {}):
pass
print(foo.__annotations__)
this outputs
{'opts': <class 'dict'>}
It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.
I strongly advise against using mutable keyword arguments. More information here.
The old way:
xcopy [source] [destination] /E
xcopy is deprecated. Robocopy replaces Xcopy. It comes with Windows 8, 8.1 and 10.
robocopy [source] [destination] /E
robocopy has several advantages:

This isn't published on Arduino.cc but you can in fact exit from the loop routine with a simple exit(0);
This will compile on pretty much any board you have in your board list. I'm using IDE 1.0.6. I've tested it with Uno, Mega, Micro Pro and even the Adafruit Trinket
void loop() {
// All of your code here
/* Note you should clean up any of your I/O here as on exit,
all 'ON'outputs remain HIGH */
// Exit the loop
exit(0); //The 0 is required to prevent compile error.
}
I use this in projects where I wire in a button to the reset pin. Basically your loop runs until exit(0); and then just persists in the last state. I've made some robots for my kids, and each time the press a button (reset) the code starts from the start of the loop() function.
it will automatically create a .gitignore
file if not then create a file name .gitignore
and add copy & paste the below code
# dependencies
/node_modules
/.pnp
.pnp.js
# testing
/coverage
# production
/build
# misc
.DS_Store
.env.local
.env.development.local
.env.test.local
.env.production.local
npm-debug.log*
yarn-debug.log*
yarn-error.log*
these below are all unnecessary files
See https://help.github.com/articles/ignoring-files/ for more about ignoring files.
and save the .gitignore
file and you can upload
Another option is to use
#include <process.h>
system("pause");
Though this is not very portable because it will only work on Windows, but it will automatically print

In our case we were getting UnmarshalException because a wrong Java package was specified in the following. The issue was resolved once the right package was in place:
@Bean
public Unmarshaller tmsUnmarshaller() {
final Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller
.setPackagesToScan("java.package.to.generated.java.classes.for.xsd");
return jaxb2Marshaller;
}
Header exists:
if (Request.Headers["XYZComponent"] != null)
or even better:
string xyzHeader = Request.Headers["XYZComponent"];
bool isXYZ;
if (bool.TryParse(xyzHeader, out isXYZ) && isXYZ)
which will check whether it is set to true. This should be fool-proof because it does not care on leading/trailing whitespace and is case-insensitive (bool.TryParse
does work on null
)
Addon: You could make this more simple with this extension method which returns a nullable boolean. It should work on both invalid input and null.
public static bool? ToBoolean(this string s)
{
bool result;
if (bool.TryParse(s, out result))
return result;
else
return null;
}
Usage (because this is an extension method and not instance method this will not throw an exception on null
- it may be confusing, though):
if (Request.Headers["XYZComponent"].ToBoolean() == true)
It's really simple,just add image to background of you button and give text to titlelabel of button for uicontrolstatenormal. That's it.
[btn setBackgroundImage:[UIImage imageNamed:@"img.png"] forState:UIControlStateNormal];
[btn setContentVerticalAlignment:UIControlContentVerticalAlignmentBottom];
[btn setTitle:@"Click Me" forState:UIControlStateNormal];
Unless otherwise definied (<tfoot>
, <thead>
), browsers put <tr>
implicitly in a <tbody>
.
You need to put a > tbody
in between > table
and > tr
:
$("div.custList > table > tbody > tr")
Alternatively, you can also be less strict in selecting the rows (the >
denotes the immediate child):
$("div.custList table tr")
That said, you can get the immediate <td>
children there by $(this).children('td')
.
Using pure Java 8
Assumming you want to extract param "v" from url:
String paramV = Stream.of(url.split("?")[1].split("&"))
.map(kv -> kv.split("="))
.filter(kv -> "v".equalsIgnoreCase(kv[0]))
.map(kv -> kv[1])
.findFirst()
.orElse("");
Running this little piece of code allowed me to understand the order function
x <- c(3, 22, 5, 1, 77)

order=order(x),
sort=sort(x)

There are 3 ways to allow cross domain origin (excluding jsonp
):
1) Set the header in the page directly using a templating language like PHP. Keep in mind there can be no HTML before your header or it will fail.
<?php header("Access-Control-Allow-Origin: http://example.com"); ?>
2) Modify the server configuration file (apache.conf
) and add this line. Note that "*"
represents allow all. Some systems might also need the credential set. In general allow all access is a security risk and should be avoided:
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Credentials true
3) To allow multiple domains on Apache web servers add the following to your config file
<IfModule mod_headers.c>
SetEnvIf Origin "http(s)?://(www\.)?(example.org|example.com)$" AccessControlAllowOrigin=$0$1
Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header set Access-Control-Allow-Credentials true
</IfModule>
4) For development use only hack your browser and allow unlimited CORS using the Chrome Allow-Control-Allow-Origin extension
5) Disable CORS in Chrome: Quit Chrome completely. Open a terminal and execute the following. Just be cautious you are disabling web security:
open -a Google\ Chrome --args --disable-web-security --user-data-dir
dir /s *foo*
searches in current folder and sub folders.
It finds directories as well as files.
where /s means(documentation):
/s Lists every occurrence of the specified file name within the specified directory and all subdirectories.
This is for format the date?
def format_date(day, month, year):
# {} betekent 'plaats hier stringvoorstelling van volgend argument'
return "{}/{}/{}".format(day, month, year)
for i=1,#target do
game.Players.target[i].Character:BreakJoints()
end
Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:
game.Players.target.1.Character:BreakJoints()
Which is completely incorrect.
c = game.Players:GetChildren()
Never use "Players:GetChildren()", it is not guaranteed to return only players.
Instead use:
c = Game.Players:GetPlayers()
if msg:lower()=="me" then
table.insert(people, source)
return people
Here you add the player's name in the list "people", where you in the other places adds the player object.
Fixed code:
local Admins = {"FakeNameHereSoNoStalkers"}
function Kill(Players)
for i,Player in ipairs(Players) do
if Player.Character then
Player.Character:BreakJoints()
end
end
end
function IsAdmin(Player)
for i,AdminName in ipairs(Admins) do
if Player.Name:lower() == AdminName:lower() then return true end
end
return false
end
function GetPlayers(Player,Msg)
local Targets = {}
local Players = Game.Players:GetPlayers()
if Msg:lower() == "me" then
Targets = { Player }
elseif Msg:lower() == "all" then
Targets = Players
elseif Msg:lower() == "others" then
for i,Plr in ipairs(Players) do
if Plr ~= Player then
table.insert(Targets,Plr)
end
end

In the world of web development, the device pixel ratio (also called CSS Pixel Ratio) is what determines how a device's screen resolution is interpreted by the CSS.
A browser's CSS calculates a device's logical (or interpreted) resolution by the formula:
For example:
Apple iPhone 6s
When viewing a web page, the CSS will think the device has a 375x667 resolution screen and Media Queries will respond as if the screen is 375x667. But the rendered elements on the screen will be twice as sharp as an actual 375x667 screen because there are twice as many physical pixels in the physical screen.
Some other examples:
Samsung Galaxy S4
iPhone 5s
The reason that CSS pixel ratio was created is because as phones screens get higher resolutions, if every device still had a CSS pixel ratio of 1 then webpages would render too small to see.
A typical full screen desktop monitor is a roughly 24" at 1920x1080 resolution. Imagine if that monitor was shrunk down to about 5" but had the same resolution. Viewing things on the screen would be impossible because they would be so small. But manufactures are coming out with 1920x1080 resolution phone screens consistently now.
So the device pixel ratio was invented by phone makers so that they could continue to push the resolution, sharpness and quality of phone screens, without making elements on the screen too small to see or read.
Here is a tool that also tells you your current device's pixel density:
As part of trying to answer one of my own questions here, I came across this trick.
In the API Gateway mapping template, use the following to give you the complete query string as sent by the HTTP client:
{
"querystring": "$input.params().querystring"
}
The advantage is that you don't have to limit yourself to a set of predefined mapped keys in your query string. Now you can accept any key-value pairs in the query string, if this is how you want to handle.
Note: According to this, only $input.params(x)
is listed as a variable made available for the VTL template. It is possible that the internals might change and querystring
may no longer be available.
You also can use in this form:
<a href="@Url.Action("Information", "Admin", null)"> Admin</a>
You can do it with a sub-query:
SELECT * FROM (
SELECT * FROM table ORDER BY id DESC LIMIT 50
) sub
ORDER BY id ASC
This will select the last 50 rows from table
, and then order them in ascending order.
SLF4J 1.5.11 and 1.6.0 versions are not compatible (see compatibility report) because the argument list of org.slf4j.spi.LocationAwareLogger.log
method has been changed (added Object[] p5):
SLF4J 1.5.11:
LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
String p4, Throwable p5 )
SLF4J 1.6.0:
LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
String p4, Object[] p5, Throwable p6 )
See compatibility reports for other SLF4J versions on this page.
You can generate such reports by the japi-compliance-checker tool.
Check out FPDF (with FPDI):
http://www.setasign.de/products/pdf-php-solutions/fpdi/
These will let you open an pdf and add content to it in PHP. I'm guessing you can also use their functionality to search through the existing content for the values you need.
Another possible library is TCPDF: https://tcpdf.org/
Update to add a more modern library: PDF Parser
In the simple setup you are likely using, getchar
works with buffered input, so you have to press enter before getchar gets anything to read. Strings are not terminated by EOF
; in fact, EOF
is not really a character, but a magic value that indicates the end of the file. But EOF
is not part of the string read. It's what getchar
returns when there is nothing left to read.
Why do you have the brackets around digit
?
It should be
NSLog("%@", digit);
You're also missing an =
in the first line...
NSString *digit = [[sender titlelabel] text];
pgrep -f youAppFile.py | xargs kill -9
pgrep
returns the PID of the specific file will only kill the specific application.
This problem may occur because of skype installation in the system. Skype and apache service always conflict. Make sure your skype is not started before starting xampp.
If you want to use \newcommand
, you can also include \usepackage{xspace}
and define command by \newcommand{\newCommandName}{text to insert\xspace}
.
This can allow you to just use \newCommandName
rather than \newCommandName{}
.

You can also have several workspaces - so you can connect to one and have set "A" of projects - and then connect to a different set when ever you like.
You're looking for os.path.isdir
, or os.path.exists
if you don't care whether it's a file or a directory:
>>> import os
>>> os.path.isdir('new_folder')
True
>>> os.path.exists(os.path.join(os.getcwd(), 'new_folder', 'file.txt'))
False
Alternatively, you can use pathlib
:
>>> from pathlib import Path
>>> Path('new_folder').is_dir()
True
>>> (Path.cwd() / 'new_folder' / 'file.txt').exists()
False
Though this is not directly related to the OP's exact question but I just found out that using a Oracle reserved word in your query (in my case the alias IN
) can cause the same error.
Example:
SELECT * FROM TBL_INDEPENTS IN
JOIN TBL_VOTERS VO on IN.VOTERID = VO.VOTERID
Or if its in the query itself as a field name
SELECT ..., ...., IN, ..., .... FROM SOMETABLE
That would also throw that error. I hope this helps someone.
Based on previous statements, for better performance, you can also add an if condition
if (player.isPlaying() {
handler.postDelayed(..., 1000);
}
The problem happens when a floated element is within a container box, that element does not automatically force the container’s height adjust to the floated element. When an element is floated, its parent no longer contains it because the float is removed from the flow. You can use 2 methods to fix it:
{ clear: both; }
clearfix
Once you understand what is happening, use the method below to “clearfix” it.
.clearfix:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
line-height: 0;
height: 0;
}
.clearfix {
display: inline-block;
}
html[xmlns] .clearfix {
display: block;
}
* html .clearfix {
height: 1%;
}
If you're using ctx.drawImage()
function, you can do the following:
var img = loadImage('../yourimage.png', callback);
function loadImage(src, callback) {
var img = new Image();
img.onload = callback;
img.setAttribute('crossorigin', 'anonymous'); // works for me
img.src = src;
return img;
}
And in your callback you can now use ctx.drawImage
and export it using toDataURL
I hate commenting on such a screwed up situation, but the easiest way to not rejigger all of your invariants is to create a phantom vertex in your graph that acts as a proxy back to the incestuous dad.
I recently had the same issue on OS X Sierra with bash shell, and thanks to answers above I only had to edit the file
~/.bash_profile
and append those lines
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
As string[]
implements IEnumerable
IEnumerable<string> m_oEnum = new string[] {"1","2","3"}
well for what its worth now... JsonProperty is ALSO used to specify getter and setter methods for the variable apart from usual serialization and deserialization. For example suppose you have a payload like this:
{
"check": true
}
and a Deserializer class:
public class Check {
@JsonProperty("check") // It is needed else Jackson will look got getCheck method and will fail
private Boolean check;
public Boolean isCheck() {
return check;
}
}
Then in this case JsonProperty annotation is neeeded. However if you also have a method in the class
public class Check {
//@JsonProperty("check") Not needed anymore
private Boolean check;
public Boolean getCheck() {
return check;
}
}
Have a look at this documentation too: http://fasterxml.github.io/jackson-annotations/javadoc/2.3.0/com/fasterxml/jackson/annotation/JsonProperty.html
Firstly, you can not shift a byte
in java, you can only shift an int
or a long
. So the byte
will undergo promotion first, e.g.
00101011
-> 00000000000000000000000000101011
or
11010100
-> 11111111111111111111111111010100
Now, x >> N
means (if you view it as a string of binary digits):
00000000000000000000000000101011 >> 2
-> 00000000000000000000000000001010
11111111111111111111111111010100 >> 2
-> 11111111111111111111111111110101
Instead, you can open particular app's general settings with one line
startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
I certainly don't know the details on this because I've never done it it, but the native NT API has a capability to fork a process (the POSIX subsystem on Windows needs this capability - I'm not sure if the POSIX subsystem is even supported anymore).
A search for ZwCreateProcess() should get you some more details - for example this bit of information from Maxim Shatskih:
The most important parameter here is SectionHandle. If this parameter is NULL, the kernel will fork the current process. Otherwise, this parameter must be a handle of the SEC_IMAGE section object created on the EXE file before calling ZwCreateProcess().
Though note that Corinna Vinschen indicates that Cygwin found using ZwCreateProcess() still unreliable:
Iker Arizmendi wrote:
> Because the Cygwin project relied solely on Win32 APIs its fork > implementation is non-COW and inefficient in those cases where a fork > is not followed by exec. It's also rather complex.

This document is rather old, 10 years or so. While we're still using Win32 calls to emulate fork, the method has changed noticably. Especially, we don't create the child process in the suspended state anymore, unless specific datastructes need a special handling in the parent before they get copied to the child. In the current 1.5.25 release the only case for a suspended child are open sockets in the parent. The upcoming 1.7.0 release will not suspend at all.
One reason not to use ZwCreateProcess was that up to the 1.5.25 release we're still supporting Windows 9x users. However, two attempts to use ZwCreateProcess on NT-based systems failed for one reason or another.
It would be really nice if this stuff would be better or at all documented, especially a couple of datastructures and how to connect a process to a subsystem. While fork is not a Win32 concept, I don't see that it would be a bad thing to make fork easier to implement.
is_numeric would accept "-0.5e+12" as a valid ID.
This method worked for me:
if ("username" in localStorage) {
alert('yes');
} else {
alert('no');
}
Many answers are right. In AndroidManifest
I wrote:
<activity
android:name=".SomeActivity"
android:configChanges="orientation|keyboardHidden|screenSize" // Optional, doesn't affect.
android:theme="@style/AppTheme.NoActionBar"
android:windowSoftInputMode="adjustResize" />
In my case I added a theme in styles.xml
, but you can use your own:
<style name="AppTheme.NoActionBar" parent="AppTheme">
<!-- Hide ActionBar -->
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
</style>
I noiced that if I use full-screen theme, resizing doesn't occur:
<style name="AppTheme.FullScreenTheme" parent="AppTheme">
<!-- Hide ActionBar -->
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<!-- Hide StatusBar -->
<item name="android:windowFullscreen">true</item>
</style>
Also in my case adjustResize
works, but adjustPan
doesn't.
For full-screen layouts see a workaround in Android How to adjust layout in Full Screen Mode when softkeyboard is visible or in https://gist.github.com/grennis/2e3cd5f7a9238c59861015ce0a7c5584.
Also https://medium.com/@sandeeptengale/problem-solved-3-android-full-screen-view-translucent-scrollview-adjustresize-keyboard-b0547c7ced32 works, but it's StatusBar is transparent, so battery, clock, Wi-Fi icons are visible.
If you create an activity with File > New > Activity > Fullscreen Activity, where in code is used:
fullscreen_content.systemUiVisibility =
View.SYSTEM_UI_FLAG_LOW_PROFILE or
View.SYSTEM_UI_FLAG_FULLSCREEN or
View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION or
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
you also won't achieve a result. You can use android:fitsSystemWindows="true"
in a root container, but StatusBar appears. So use workarounds from the first link.
array_splice($array, 0, 1);
I have got that error after update to JDK 1.8. But the JAVA_HOME
variable was hard coded furthermore to JDK 1.7. Thew modification solved the problem:
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_241
You can have multiple tags when building the image:
$ docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 .
Reference: https://docs.docker.com/engine/reference/commandline/build/#tag-image-t
In order to avoid path problem, you can simply try this, just keep background image in images folder and add this code
<Grid>
<Grid.Background>
<ImageBrush Stretch="Fill" ImageSource="..\Images\background.jpg"
AlignmentY="Top" AlignmentX="Center"/>
</Grid.Background>
</Grid>
Problem:
Your View
cannot be found in default locations.
Explanation:
Views should be in the same folder named as the Controller
or in the Shared
folder.
Solution:
Either move your View
to the MyAccount
folder or create a HomeController
.
Alternatives:
If you don't want to move your View
or create a new Controller

late in the game , but this worked for me:
$("#container>table>tbody>tr:first").trigger('click');
+
is called the Union operator, which differs from a Concatenation operator (PHP doesn't have one for arrays). The description clearly says:
The + operator appends elements of remaining keys from the right handed array to the left handed, whereas duplicated keys are NOT overwritten.
With the example:
$a = array("a" => "apple", "b" => "banana");
$b = array("a" => "pear", "b" => "strawberry", "c" => "cherry");
$c = $a + $b;
array(3) {
["a"]=>
string(5) "apple"
["b"]=>
string(6) "banana"
["c"]=>
string(6) "cherry"
}
Since both your arrays have one entry with the key 0
, the result is expected.
To concatenate, use array_merge
.
$(selector).filter(function(){return this.value==yourval}).remove();
I was looking for the same thing and I've just seen that MySQL 5.6 has a couple of new string functions supporting this functionality: TO_BASE64 and FROM_BASE64.
private void positionsListView_DoubleClick(object sender, EventArgs e)
{
if (positionsListView.SelectedItems.Count == 1)
{
ListView.SelectedListViewItemCollection items = positionsListView.SelectedItems;
ListViewItem lvItem = items[0];
string what = lvItem.Text;
}
}
Starting from Java 8 you can use Stream
:
List<String> sorted = Arrays.asList(
names.stream().sorted(
(s1, s2) -> s1.compareToIgnoreCase(s2)
).toArray(String[]::new)
);
It gets a stream from that ArrayList
, then it sorts it (ignoring the case). After that, the stream is converted to an array which is converted to an ArrayList
.
If you print the result using:
System.out.println(sorted);
you get the following output:
[ananya, Athira, bala, jeena, Karthika, Neethu, Nithin, seetha, sudhin, Swetha, Tony, Vinod]
try overflow hidden on the thing you don't want to scroll while touch event is happening. e.g set overflow hidden on Start and set it back to auto on end.
Did you try it ? I'd be interested to know if this would work.
document.addEventListener('ontouchstart', function(e) {
document.body.style.overflow = "hidden";
}, false);
document.addEventListener('ontouchmove', function(e) {
document.body.style.overflow = "auto";
}, false);
one of the simplest ways to create a string matrix is as follow :
x = [ {'first string'} {'Second parameter} {'Third text'} {'Fourth component'} ]
We can simply connect to the database like this:
uid=username;pwd=password;database=databasename;server=servername
For example:
string connectionString = @"uid=spacecraftU1;pwd=Appolo11;
database=spacecraft_db;
server=DESKTOP-99K0FRS\\PRANEETHDB";
SqlConnection con = new SqlConnection(connectionString);
The guarantees the standard gives you go like this:
1 == sizeof(char) <= sizeof(short) <= sizeof (int) <= sizeof(long) <= sizeof(long long)
So it's perfectly valid for sizeof (int)
and sizeof (long)
to be equal, and many platforms choose to go with this approach. You will find some platforms where int
is 32 bits, long
is 64 bits, and long long
is 128 bits, but it seems very common for sizeof (long)
to be 4.
(Note that long long
is recognized in C from C99 onwards, but was normally implemented as an extension in C++ prior to C++11.)
You are missing default density value of 160.
2 px = 3 dip if dpi == 80(ldpi), 320x240 screen
1 px = 1 dip if dpi == 160(mdpi), 480x320 screen
3 px = 2 dip if dpi == 240(hdpi), 840x480 screen
In other words, if you design you layout with width equal to 160dip in portrait mode, it will be half of the screen on all ldpi/mdpi/hdpi devices(except tablets, I think)
Quick way if you have change on your current project and don't want to lose it , move your current project some where , clone the project from github to this folder and make some change an try to commit again. Or just delete the repo and clone it again , it worked form me .
Use this simple way hope it will helpful
foreach($array as $k => $value)
{
if($value == 'strawberry')
{
unset($array[$k]);
}
}
You can use Reflections framework for this
import static org.reflections.ReflectionUtils.*;
Set<Method> getters = ReflectionUtils.getAllMethods(someClass,
withModifier(Modifier.PUBLIC), withPrefix("get"), withAnnotation(annotation));
The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.
Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.
If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/
is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/
or http://s3-external-1.amazonaws.com/bucket/
.¹
The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].
S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com
. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.
If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.
However... the two endpoints do not offer the same functionality.
Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.
Choose the correct type of endpoint (REST or web site) for your application:
http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff
¹ s3-external-1.amazonaws.com
has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com
. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2
had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1
so s3-external-2
appears to have no purpose except backwards-compatibility.
If you are looking for an answer in java code,
LinearLayout linearLayout = new LinearLayout(context);

One of the above answer states to convert XML String to bytes which is not needed. Instead you can can use InputSource
and supply it with StringReader
.
String xmlStr = "<message>HELLO!</message>";
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(xmlStr)));
System.out.println(doc.getFirstChild().getNodeValue());
I'm assuming in your scenario, an empty string is a string that is truly empty or one that contains all white space.
if(str.strip()):
print("string is not empty")
else:
print("string is empty")
Note this does not check for None

Would use character positions 4-5 in the first field (it's all one field for fixed width) and sort numerically as the first key.
The second key would be characters 14-15 in the first field also.

I was interested to see that the original poster used a style that avoided early exits. Single Entry; Single Exit (SESE) is an interesting style that I've not really explored. It's late and I've got a bottle of cider, so I've written a solution (not tested) without an early exit.
I should have used an iterator. Unfortunately java.util.Iterator
has a side-effect in the get method. (I don't like the Iterator
design due to its exception ramifications.)
private Dog findDog(int id) {
int i = 0;
for (; i!=dogs.length() && dogs.get(i).getID()!=id; ++i) {
;
}
return i!=dogs.length() ? dogs.get(i) : null;
}
Note the duplication of the i!=dogs.length()
expression (could have chosen dogs.get(i).getID()!=id
).
This should only allow decimals > 0

You can use one of DatePicker library
wdullaer/MaterialDateTimePicker
First show DatePicker.
private void showDatePicker() {
Calendar now = Calendar.getInstance();
DatePickerDialog dpd = DatePickerDialog.newInstance(
HomeActivity.this,
now.get(Calendar.YEAR),
now.get(Calendar.MONTH),
now.get(Calendar.DAY_OF_MONTH)
);
dpd.show(getFragmentManager(), "Choose Date:");
}
Then onDateSet callback store date & show TimePicker
@Override
public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
Calendar cal = Calendar.getInstance();
cal.set(year, monthOfYear, dayOfMonth);
filter.setDate(cal.getTime());
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
showTimePicker();
}
},500);
}
On onTimeSet callback
store time

An alternative that I used instead of FFServer was Red5 Pro, on Ubuntu, I used this line:

array_unique(array_merge($array1,$array2), SORT_REGULAR);
The Chr
function in VB.NET converts the integer back to the character:
Dim i As Integer = Asc("x") ' Convert to ASCII integer.
Dim x As Char = Chr(i) ' Convert ASCII integer to char.
For a solution that works for values in multiple rows and columns, I found the following formula very useful, from http://www.get-digital-help.com/2009/03/16/unique-values-from-multiple-columns-using-array-formulas/ Oscar at get-digital.help.com even goes through it step-by-step and with a visualized example.
1) Give the range of values the label tbl_text
2) Apply the following array formula with CTRL + SHIFT + ENTER, to cell B13 in this case. Change $B$12:B12 to refer to the cell above the cell you enter this formula into.
=INDEX(tbl_text, MIN(IF(COUNTIF($B$12:B12, tbl_text)=0, ROW(tbl_text)-MIN(ROW(tbl_text))+1)), MATCH(0, COUNTIF($B$12:B12, INDEX(tbl_text, MIN(IF(COUNTIF($B$12:B12, tbl_text)=0, ROW(tbl_text)-MIN(ROW(tbl_text))+1)), , 1)), 0), 1)
3) Copy/drag down until you get N/A's.
To pass multiple arguments to a map
function.
def q(x,y):
return x*y
print map (q,range(0,10),range(10,20))
Here q is function with multiple argument that map() calls. Make sure, the length of both the ranges i.e.
len (range(a,a')) and len (range(b,b')) are equal.
I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker
Base = declarative_base()
class MyTable(Base):
__tablename__ = 'MyTable'
id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
some_col = Column(String(500))
def __init__(self, some_col):
self.some_col = some_col
engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()
for class_instance in session.query(MyTable).all():
print(vars(class_instance))
session.close()
There is no import aliasing mechanism in Java. You cannot import two classes with the same name and use both of them unqualified.
Import one class and use the fully qualified name for the other one, i.e.
import com.text.Formatter;
private Formatter textFormatter;
private com.json.Formatter jsonFormatter;
Look at snprintf or, if GNU extensions are OK, asprintf (which will allocate memory for you).
it worked for me: I use Mac and I wrote the path on finder:
~/Library/Application Support/SourceTree
I deleted the auth file which should be like
then tried to push and pull the code from the source tree and it worked.
You can also read the following answers:
As of Apache POI 3.17 you will have to check if the cell is empty using enumerations:
import org.apache.poi.ss.usermodel.CellType;
if(cell == null || cell.getCellTypeEnum() == CellType.BLANK) { ... }
A funny way to remove all spaces from a variable is to use printf:
$ myvar='a cool variable with lots of spaces in it'
$ printf -v myvar '%s' $myvar
$ echo "$myvar"
acoolvariablewithlotsofspacesinit
It turns out it's slightly more efficient than myvar="${myvar// /}"
, but not safe regarding globs (*
) that can appear in the string. So don't use it in production code.
If you really really want to use this method and are really worried about the globbing thing (and you really should), you can use set -f
(which disables globbing altogether):
$ ls
file1 file2
$ myvar=' a cool variable with spaces and oh! no! there is a glob * in it'
$ echo "$myvar"
a cool variable with spaces and oh! no! there is a glob * in it
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglobfile1file2init
$ # See the trouble? Let's fix it with set -f:
$ set -f
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglob*init
$ # Since we like globbing, we unset the f option:
$ set +f
I posted this answer just because it's funny, not to use it in practice.
I highly recommend the book "Pro Git" by Scott Chacon. Take time and really read it, while exploring an actual git repo as you do.
HEAD: the current commit your repo is on. Most of the time HEAD
points to the latest commit in your current branch, but that doesn't have to be the case. HEAD
really just means "what is my repo currently pointing at".
In the event that the commit HEAD
refers to is not the tip of any branch, this is called a "detached head".
master: the name of the default branch that git creates for you when first creating a repo. In most cases, "master" means "the main branch". Most shops have everyone pushing to master, and master is considered the definitive view of the repo. But it's also common for release branches to be made off of master for releasing. Your local repo has its own master branch, that almost always follows the master of a remote repo.
origin: the default name that git gives to your main remote repo. Your box has its own repo, and you most likely push out to some remote repo that you and all your coworkers push to. That remote repo is almost always called origin, but it doesn't have to be.
HEAD
is an official notion in git. HEAD
always has a well-defined meaning. master
and origin
are common names usually used in git, but they don't have to be.
You can stop the docker container and once it is stopped you can remove the container.
Stop the container:
$ docker stop "containerID" - you can also mention the first two letters of the container ID, and it works.
Remove the container
$ docker rm "containerID" - again you can also mention the first two letters of the container
If these command do not let you stop/remove the containers, m,ake sure you have sudo access to docker host.
For anyone who might still need this in the future. My answer is very similar to qaweb, just a lot less intimidating. There seems to be no cool automatic simple function to formate date in VBS. So you'll have to do it manually. I took the different components of the date and concatenated them together.
Dim timeStamp
timeStamp = Month(Date)&"-"&Day(Date)&"-"&Year(Date)
run = msgbox(timeStamp)
Which will result in 11-22-2019
(depending on the current date)
I find this particularly useful for when you want to 'store' a function call.
For example, suppose I have some unit tests for a function 'add':
def add(a, b): return a + b
tests = { (1,4):5, (0, 0):0, (-1, 3):3 }
for test, result in tests.items():
print 'test: adding', test, '==', result, '---', add(*test) == result
There is no other way to call add, other than manually doing something like add(test[0], test[1])
, which is ugly. Also, if there are a variable number of variables, the code could get pretty ugly with all the if-statements you would need.
Another place this is useful is for defining Factory objects (objects that create objects for you).
Suppose you have some class Factory, that makes Car objects and returns them.
You could make it so that myFactory.make_car('red', 'bmw', '335ix')
creates Car('red', 'bmw', '335ix')
, then returns it.
def make_car(*args):
return Car(*args)
This is also useful when you want to call a superclass' constructor.
The BR is anything but 'extra-special': it is still a valid XML tag that you can give attributes to. For example, you don't have to encase it with a span to change the line-height, rather you can apply the line height directly to the element.
You could do it with inline CSS:
This is a small line_x000D_
<br />_x000D_
break. Whereas, this is a BIG line_x000D_
<br />_x000D_
<br style="line-height:40vh"/>_x000D_
break!
_x000D_
Notice how two line breaks were used instead of one. This is because of how CSS inline elements work. Unfourtunately, the most awesome css feature possible (the lh
unit) is still not there yet with any browser compatibility as of 2019. Thus, I have to use JavaScript for the demo below.
addEventListener("load", function(document, getComputedStyle){"use strict";_x000D_
var allShowLineHeights = document.getElementsByClassName("show-lh");_x000D_
for (var i=0; i < allShowLineHeights.length; i=i+1|0) {_x000D_
allShowLineHeights[i].textContent = getComputedStyle(_x000D_
allShowLineHeights[i]_x000D_
).lineHeight;_x000D_
}_x000D_
}.bind(null, document, getComputedStyle), {once: 1, passive: 1});
_x000D_
.show-lh {padding: 0 .25em}_x000D_
.r {background: #f77}_x000D_
.g {background: #7f5}_x000D_
.b {background: #7cf}
_x000D_
This is a small line_x000D_
<span class="show-lh r"></span><br /><span class="show-lh r"></span>_x000D_
break. Whereas, this is a BIG line_x000D_
<span class="show-lh g"></span><br /><span class="show-lh g"></span>_x000D_
<span class="show-lh b"></span><br style="line-height:40vh"/><span class="show-lh b"></span>_x000D_
break!
_x000D_
You can even use any CSS selectors you want like ID's and classes.
#biglinebreakid {_x000D_
line-height: 450%;_x000D_
// 9x the normal height of a line break!_x000D_
}_x000D_
.biglinebreakclass {_x000D_
line-height: 1em;_x000D_
// you could even use calc!_x000D_
}
_x000D_
This is a small line_x000D_
<br />_x000D_
break. Whereas, this is a BIG line_x000D_
<br />_x000D_
<br id="biglinebreakid" />_x000D_
break! You can use any CSS selectors you want for things like this line_x000D_
<br />_x000D_
<br class="biglinebreakclass" />_x000D_
break!
_x000D_
You can find our more about line-height at the W3C docs.
Basically, BR tags are not some void in world of CSS styling: they still can be styled. However, I would recommend only using line-height
to style BR tags. They were never intended to be anything more than a line-break, and as such they might not always work as expected when using them as something else. Observe how even after applying tons of visual effects, the line break is still invisible:
#paddedlinebreak {_x000D_
display: block;_x000D_
width: 6em;_x000D_
height: 6em;_x000D_
background: orange;_x000D_
line-height: calc(6em + 100%);_x000D_
outline: 1px solid red;_x000D_
border: 1px solid green;_x000D_
}
_x000D_
<div style="outline: 1px solid yellow;margin:1em;display:inline-block;overflow:visible">_x000D_
This is a padded line_x000D_
<br id="paddedlinebreak" />_x000D_
break._x000D_
</div>
_x000D_
A work-around for things such as margins and paddings is to instead style a span with a br in it like so.
#paddedlinebreak {_x000D_
background: orange;_x000D_
line-height: calc(6em + 100%);_x000D_
padding: 3em;_x000D_
}
_x000D_
<div style="outline: 1px solid yellow;margin:1em;display:inline-block;overflow:visible">_x000D_
This is a padded line_x000D_
<span id="paddedlinebreak"><br /></span>_x000D_
break._x000D_
</div>
_x000D_
Notice how the orange blob above is the span that contains the br.
You can choose one of the below solutions as you wish.
[0,4,8,2,5,0,2,6].sum.to_f / [0,4,8,2,5,0,2,6].size.to_f
=> 3.375
def avg(array)
array.sum.to_f / array.size.to_f
end
avg([0,4,8,2,5,0,2,6])
=> 3.375
class Array
def avg
sum.to_f / size.to_f
end
end
[0,4,8,2,5,0,2,6].avg
=> 3.375
But I don't recommend to monkey patch the Array class, this practice is dangerous and can potentially lead to undesirable effects on your system.
For our good, ruby language provides a nice feature to overcome this problem, the Refinements, which is a safe way for monkey patching on ruby.
To simplify, with the Refinements you can monkey patch the Array
class and the changes will only be available inside the scope of the class that is using the refinement! :)
You can use the refinement inside the class you are working on and you are ready to go.
module ArrayRefinements
refine Array do
def avg
sum.to_f / size.to_f
end
end
end
class MyClass
using ArrayRefinements
def test(array)
array.avg
end
end
MyClass.new.test([0,4,8,2,5,0,2,6])
=> 3.375
I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer
As others said, they produce identical output on printf, but behave differently on scanf. I would prefer %d
over %i
for this reason. A number that is printed with %d
can be read in with %d
and you will get the same number. That is not always true with %i
, if you ever choose to use zero padding. Because it is common to copy printf format strings into scanf format strings, I would avoid %i
, since it could give you a surprising bug introduction:
I write fprintf("%i ...", ...);
You copy and write fscanf(%i ...", ...);
I decide I want to align columns more nicely and make alphabetization behave the same as sorting: fprintf("%03i ...", ...);
(or %04d
)
Now when you read my numbers, anything between 10 and 99 is interpreted in octal. Oops.
If you want decimal formatting, just say so.
Different solution for those still having issues. Hopefully I can help those trying to reinstall Mysql. Note, It's a seek and destroy mission. So be weary. Assuming your root:
apt-get purge mysql*
apt-get purge dbconfig-common #the screen used for mysql password
find / -name *mysql* #delete any traces of mysql
#insert apt-get cleanups, autoremove,updates etc.
Originally, something leftover was interfering with my startup of mysqlserver-5.5. These commands ended up resolving the issue for myself.
Add a reference to the Outlook object model in the Visual Basic editor. Then you can use the code below to send an email using outlook.
Sub sendOutlookEmail()
Dim oApp As Outlook.Application
Dim oMail As MailItem
Set oApp = CreateObject("Outlook.application")
Set oMail = oApp.CreateItem(olMailItem)
oMail.Body = "Body of the email"
oMail.Subject = "Test Subject"
oMail.To = "[email protected]"
oMail.Send
Set oMail = Nothing
Set oApp = Nothing
End Sub
All STL container are externally represented as "sequences" with one iteration mechanism. Trees don't follow this idiom.
