I would avoid using a relative path. Remember that docker is a daemon/client relationship.
When you are executing the compose, it's essentially just breaking down into various docker client commands, which are then passed to the daemon. That ./database
is then relative to the daemon, not the client.
Now, the docker dev team has some back and forth on this issue, but the bottom line is it can have some unexpected results.
In short, don't use a relative path, use an absolute path.
The data container is a superfluous workaround. Data-volumes would do the trick for you. Alter your docker-compose.yml
to:
version: '2'
services:
mysql:
container_name: flask_mysql
restart: always
image: mysql:latest
environment:
MYSQL_ROOT_PASSWORD: 'test_pass' # TODO: Change this
MYSQL_USER: 'test'
MYSQL_PASS: 'pass'
volumes:
- my-datavolume:/var/lib/mysql
volumes:
my-datavolume:
Docker will create the volume for you in the /var/lib/docker/volumes
folder. This volume persist as long as you are not typing docker-compose down -v
Convert timeofday to string to use indexOf
var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;
console.log(typeof(timeofday)) // for testing will log number
function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)
var pos = time.indexOf('.');
var hrs = time.substr(1, pos - 1);
var min = (time.substr(pos, 2)) * 60;
if (hrs > 11) {
hrs = (hrs - 12) + ":" + min + " PM";
} else {
hrs += ":" + min + " AM";
}
return hrs;
}
// "" for typecasting to string
document.getElementById("oset").innerHTML = timeD2C(""+timeofday);
Solution 2
use toString()
to convert to string
document.getElementById("oset").innerHTML = timeD2C(timeofday.toString());
You can also use mvc frameworks like Backbone.js that will provide a javascript model of the data. Changes to the model will be translated into REST calls.
Note: Most modern browsers will now allow you to navigate objects in the developer console. This answer is antiquated.
This method will walk through object properties and write them to the console with increasing indent:
function enumerate(o,s){
//if s isn't defined, set it to an empty string
s = typeof s !== 'undefined' ? s : "";
//if o is null, we need to output and bail
if(typeof o == "object" && o === null){
console.log(s+k+": null");
} else {
//iterate across o, passing keys as k and values as v
$.each(o, function(k,v){
//if v has nested depth
if(typeof v == "object" && v !== null){
//write the key to the console
console.log(s+k+": ");
//recursively call enumerate on the nested properties
enumerate(v,s+" ");
} else {
//log the key & value
console.log(s+k+": "+String(v));
}
});
}
}
Just pass it the object you want to iterate through:
var response = $.ajax({
url: myurl,
dataType: "json"
})
.done(function(a){
console.log("Returned values:");
enumerate(a);
})
.fail(function(){ console.log("request failed");});
As others have suggested, you are not clearly explaining your problem, what you are trying to do, or what your expectations are as to what this function is actually supposed to do.
If I have understood correctly, then you are expecting this function to refresh the page for you (you actually use the term "reloads the browser").
But this function is not intended to reload the browser.
All the function does, is to add (push) a new "state" onto the browser history, so that in future, the user will be able to return to this state that the web-page is now in.
Normally, this is used in conjunction with AJAX calls (which refresh only a part of the page).
For example, if a user does a search "CATS" in one of your search boxes, and the results of the search (presumably cute pictures of cats) are loaded back via AJAX, into the lower-right of your page -- then your page state will not be changed. In other words, in the near future, when the user decides that he wants to go back to his search for "CATS", he won't be able to, because the state doesn't exist in his history. He will only be able to click back to your blank search box.
Hence the need for the function
history.pushState({},"Results for `Cats`",'url.html?s=cats');
It is intended as a way to allow the programmer to specifically define his search into the user's history trail. That's all it is intended to do.
When the function is working properly, the only thing you should expect to see, is the address in your browser's address-bar change to whatever you specify in your URL.
If you already understand this, then sorry for this long preamble. But it sounds from the way you pose the question, that you have not.
As an aside, I have also found some contradictions between the way that the function is described in the documentation, and the way it works in reality. I find that it is not a good idea to use blank or empty values as parameters.
See my answer to this SO question. So I would recommend putting a description in your second parameter. From memory, this is the description that the user sees in the drop-down, when he clicks-and-holds his mouse over "back" button.
@Asahi pretty much hit the nail on the head, but I just wanted to add a bit of XML for anyone maybe floating in here later via google:
<ListView android:id="@+id/MyListView"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:divider="@android:color/transparent"
android:dividerHeight="10.0sp"/>
For some reason, values such as "10", "10.0", and "10sp" all are rejected by Android for the dividerHeight
value. It wants a floating point number and a unit, such as "10.0sp". As @Goofyahead notes, you can also use display-independent pixels for this value (ie, "10dp").
I had this problem just now and I tried the require_once trick, but it would just echo the CSS above all my php code without actually applying the styles.
What I did to fix it, though, was wrap all my php in their own plain HTML templates. Just type out html in the first line of the document and pick the suggestion html:5 to get the HTML boilerplate, like you would when you're just starting a plain HTML doc. Then cut the closing body and html tags and paste them all the way down at the bottom, below the closing php tag to wrap your php code without actually changing anything. Finally, you can just put your plain old link to your stylesheet into the head of your HTML. Works just fine.
Yes, it is significantly slower. We were running some code that did that, and while I don't have the metrics available at the moment, the end result was that we had to refactor that code to not use reflection. If you know what the class is, just call the constructor directly.
Seemed to be a no brainer; the WCF service should be enabled using Programs and Features -> Turn Windows features on or off
in the Control Panel. Go to .NET Framework Advanced Services -> WCF Services
and enable HTTP Activation
as described in this blog post on mdsn.
From the command prompt (as admin), you can run:
C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation
C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation45
If you get an error then use the below
C:\> DISM /Online /Enable-Feature /all /FeatureName:WCF-HTTP-Activation
C:\> DISM /Online /Enable-Feature /all /FeatureName:WCF-HTTP-Activation45
I am not sure what you really want here. If you want to see the .NET framework source code, you may try Netmassdownloader. It's free.
If you want to see any assembly's code (not just .NET), you can use ReSharper. Although it's not free.
exec
is not an expression: a statement in Python 2.x, and a function in Python 3.x. It compiles and immediately evaluates a statement or set of statement contained in a string. Example:
exec('print(5)') # prints 5.
# exec 'print 5' if you use Python 2.x, nor the exec neither the print is a function there
exec('print(5)\nprint(6)') # prints 5{newline}6.
exec('if True: print(6)') # prints 6.
exec('5') # does nothing and returns nothing.
eval
is a built-in function (not a statement), which evaluates an expression and returns the value that expression produces. Example:
x = eval('5') # x <- 5
x = eval('%d + 6' % x) # x <- 11
x = eval('abs(%d)' % -100) # x <- 100
x = eval('x = 5') # INVALID; assignment is not an expression.
x = eval('if 1: x = 4') # INVALID; if is a statement, not an expression.
compile
is a lower level version of exec
and eval
. It does not execute or evaluate your statements or expressions, but returns a code object that can do it. The modes are as follows:
compile(string, '', 'eval')
returns the code object that would have been executed had you done eval(string)
. Note that you cannot use statements in this mode; only a (single) expression is valid.
compile(string, '', 'exec')
returns the code object that would have been executed had you done exec(string)
. You can use any number of statements here.
compile(string, '', 'single')
is like the exec
mode but expects exactly one expression/statement, eg compile('a=1 if 1 else 3', 'myf', mode='single')

GitHub is the entire site. Gists are a particular service offered on that site, namely code snippets akin to pastebin. However, everything is driven by git revision control, so gists also have complete revision histories.
dir_is_empty() {
[ "${1##*/}" = "*" ]
}
if dir_is_empty /some/dir/* ; then
echo "huzzah"
fi
Assume you don't have a file named *
into /any/dir/you/check
, it should work on bash
dash
posh
busybox sh
and zsh
but (for zsh) require unsetopt nomatch
.
Performances should be comparable to any ls
which use *
(glob), I guess will be slow on directories with many nodes (my /usr/bin
with 3000+ files went not that slow), will use at least memory enough to allocate all dirs/filenames (and more) as they are all passed (resolved) to the function as arguments, some shell probably have limits on number of arguments and/or length of arguments.
A portable fast O(1) zero resources way to check if a directory is empty would be nice to have.
update
The version above doesn't account for hidden files/dirs, in case some more test is required, like the is_empty
from Rich’s sh (POSIX shell) tricks:
is_empty () (
cd "$1"
set -- .[!.]* ; test -f "$1" && return 1
set -- ..?* ; test -f "$1" && return 1
set -- * ; test -f "$1" && return 1
return 0 )
But, instead, I'm thinking about something like this:
dir_is_empty() {
[ "$(find "$1" -name "?*" | dd bs=$((${#1}+3)) count=1 2>/dev/null)" = "$1" ]
}
Some concern about trailing slashes differences from the argument and the find output when the dir is empty, and trailing newlines (but this should be easy to handle), sadly on my busybox
sh
show what is probably a bug on the find -> dd
pipe with the output truncated randomically (if I used cat
the output is always the same, seems to be dd
with the argument count
).
Assuming that you want to insert/update single row, most optimal approach is to use SQL Server's REPEATABLE READ
transaction isolation level:
SET TRANSACTION ISOLATION LEVEL REPEATABLE READ;
BEGIN TRANSACTION
IF (EXISTS (SELECT * FROM myTable WHERE key=@key)
UPDATE myTable SET ...
WHERE key=@key
ELSE
INSERT INTO myTable (key, ...)
VALUES (@key, ...)
COMMIT TRANSACTION
This isolation level will prevent/block subsequent repeatable read transactions from accessing same row (WHERE key=@key
) while currently running transaction is open.
On the other hand, operations on another row won't be blocked (WHERE key=@key2
).
Or with Prototype:
Event.observe(this, 'load', function() { new Ajax.Request(... ) );
Or better, define the function elsewhere rather than inline, then:
Event.observe(this, 'load', functionName );
You don't have to use jQuery or Prototype specifically, but I hope you're using some kind of library. Either library is going to handle the event handling in a more consistent manner than onload, and of course is going to make it much easier to process the Ajax call. If you must use the body onload attribute, then you should just be able to call the same function as referenced in these examples (onload="javascript:functionName();"
).
However, if your database update doesn't depend on the rendering on the page, why wait until it's fully loaded? You could just include a call to the Ajax-calling function at the end of the JavaScript on the page, which should give nearly the same effect.

You can do this without installing anything into python itself.
You don't need sudo or any privileges.
You don't need to edit any files.
Install virtualenv into a bootstrap virtual environment. Use the that virtual environment to create more. Since virtualenv ships with pip and distribute, you get everything from one install.
Here is an example in bash:
# Select current version of virtualenv:
VERSION=12.0.7
# Name your first "bootstrap" environment:
INITIAL_ENV=bootstrap
# Set to whatever python interpreter you want for your first environment:
PYTHON=$(which python)
URL_BASE=https://pypi.python.org/packages/source/v/virtualenv
# --- Real work starts here ---
curl -O $URL_BASE/virtualenv-$VERSION.tar.gz
tar xzf virtualenv-$VERSION.tar.gz
# Create the first "bootstrap" environment.
$PYTHON virtualenv-$VERSION/virtualenv.py $INITIAL_ENV
# Don't need this anymore.
rm -rf virtualenv-$VERSION
# Install virtualenv into the environment.
$INITIAL_ENV/bin/pip install virtualenv-$VERSION.tar.gz
Now you can use your "bootstrap" environment to create more:
# Create a second environment from the first:
$INITIAL_ENV/bin/virtualenv py-env1
# Create more:
$INITIAL_ENV/bin/virtualenv py-env2
Go nuts!
This assumes you are not using a really old version of virtualenv.
Old versions required the flags --no-site-packges
(and depending on the version of Python, --distribute
). Now you can create your bootstrap environment with just python virtualenv.py path-to-bootstrap
or python3 virtualenv.py path-to-bootstrap
.
I don't have rep enough to comment so I'll format an answer, yet it is only a demonstration of the issue in question.
It seems, when element styles are defined in stylesheets they are not visible to getElementById("someElement").style
This code illustrates the issue... Code from below on jsFiddle.
In Test 2, on the first call, the items left value is undefined, and so, what should be a simple toggle gets messed up. For my use I will define my important style values inline, but it does seem to partially defeat the purpose of the stylesheet.
Here's the page code...
<html>
<head>
<style type="text/css">
#test2a{
position: absolute;
left: 0px;
width: 50px;
height: 50px;
background-color: green;
border: 4px solid black;
}
#test2b{
position: absolute;
left: 55px;
width: 50px;
height: 50px;
background-color: yellow;
margin: 4px;
}
</style>
</head>

var a = document.getElementById("test1a");
var b = document.getElementById("test1b");
alert(a.style.left + " - " + b.style.left);
a.style.left = (a.style.left == "0px")? "55px" : "0px";
b.style.left = (b.style.left == "0px")? "55px" : "0px";
}

If it is something to do with the data in your database, why not utilize database isolation locking to achieve?
By default h1 is a block element and will render on the line after the first img, and will cause the second img to appear on the line following the block.
To stop this from occurring you can set the h1 to have inline flow behaviour:
#header > h1 { display: inline; }
As for absolutely positioning the img inside the div, you need to set the containing div to have a "known size" before this will work properly. In my experience, you also need to change the position attribute away from the default - position: relative works for me:
#header { position: relative; width: 20em; height: 20em; }
#img-for-abs-positioning { position: absolute; top: 0; left: 0; }
If you can get that to work, you might want to try progressively removing the height, width, position attributes from div.header to get the minimal required attributes to get the effect you want.
UPDATE:
Here is a complete example that works on Firefox 3:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

</style>
</head>
<body>
<div id="header">
<img src="#" alt="Image 1" width="40" height="40" />

You can actually index directly into the Attributes collection (if you are using C# not VB):
foreach (XmlNode xNode in nodeListName)
{
XmlNode parent = xNode.ParentNode;
if (parent.Attributes != null
&& parent.Attributes["split"] != null)
{
parentSplit = parent.Attributes["split"].Value;
}
}
Parameterize the query and pass the ids in using a Table Valued Parameter.
For example, define the following type:
CREATE TYPE IdTable AS TABLE (Id INT NOT NULL PRIMARY KEY)
Along with the following stored procedure:
CREATE PROCEDURE sp__Procedure_Name
@OrderIDs IdTable READONLY,
AS

A weak entity is the entity which can't be fully identified by its own attributes and takes the foreign key as an attribute (generally it takes the primary key of the entity it is related to) in conjunction.
Examples
The existence of rooms is entirely dependent on the existence of a hotel. So room can be seen as the weak entity of the hotel.
Another example is the
bank account of a particular bank has no existence if the bank doesn't exist anymore.
If you are using windows OS then in Gitbash terminal use the following command $source venv/Scripts/activate. This will help you to enter the virtual environment.

And what does "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.5 Safari/535.19" means ?
This is the value of User-Agent, the browser identification string.
For this reason, most Web browsers use a User-Agent string value as follows:
Mozilla/[version] ([system and browser information]) [platform] ([platform details]) [extensions]. For example, Safari on the iPad has used the following:
Mozilla/5.0 (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Mobile/7B405 The components of this string are as follows:
Mozilla/5.0: Previously used to indicate compatibility with the Mozilla rendering engine. (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us): Details of the system in which the browser is running. AppleWebKit/531.21.10: The platform the browser uses. (KHTML, like Gecko): Browser platform details. Mobile/7B405: This is used by the browser to indicate specific enhancements that are available directly in the browser or through third parties. An example of this is Microsoft Live Meeting which registers an extension so that the Live Meeting service knows if the software is already installed, which means it can provide a streamlined experience to joining meetings.
This value will be used to identify what browser is being used by end user.
It seems that you can handle the signing problem by doing a "logical AND" on the values before you use them:
Example (Value of byte[]
header[0]
is 0x86
):
System.out.println("Integer "+(int)header[0]+" = "+((int)header[0]&0xff));
Result:
Integer -122 = 134
You can use %
:
SELECT * FROM datetable WHERE datecol LIKE '2012-12-25%'
Platform.runLater
: If you need to update a GUI component from a non-GUI thread, you can use that to put your update in a queue and it will be handled by the GUI thread as soon as possible.Task
implements the Worker
interface which is used when you need to run a long task outside the GUI thread (to avoid freezing your application) but still need to interact with the GUI at some stage.If you are familiar with Swing, the former is equivalent to SwingUtilities.invokeLater
and the latter to the concept of SwingWorker
.
The javadoc of Task gives many examples which should clarify how they can be used. You can also refer to the tutorial on concurrency.
There's public static class AbstractMap.SimpleEntry<K,V>
. Don't let the Abstract
part of the name mislead you: it is in fact NOT an abstract
class (but its top-level AbstractMap
is).
The fact that it's a static
nested class means that you DON'T need an enclosing AbstractMap
instance to instantiate it, so something like this compiles fine:
Map.Entry<String,Integer> entry =
new AbstractMap.SimpleEntry<String, Integer>("exmpleString", 42);
As noted in another answer, Guava also has a convenient static
factory method Maps.immutableEntry
that you can use.
You said:
I can't use
Map.Entry
itself because apparently it's a read-only object that I can't instantiate newinstanceof
That's not entirely accurate. The reason why you can't instantiate it directly (i.e. with new
) is because it's an interface Map.Entry
.
As noted in the documentation, AbstractMap.SimpleEntry
is @since 1.6
, so if you're stuck to 5.0, then it's not available to you.
To look for another known class that implements Map.Entry
, you can in fact go directly to the javadoc. From the Java 6 version
Interface Map.Entry
All Known Implementing Classes:
Unfortunately the 1.5 version does not list any known implementing class that you can use, so you may have be stuck with implementing your own.
I have found using the jQuery .val() method to have a significant drawback.
<select id="gate"></select>
$("#gate").val("Gateway 2");
If this select box (or any other input object) is in a form and there is a reset button used in the form, when the reset button is clicked the set value will get cleared and not reset to the beginning value as you would expect.
This seems to work the best for me.
For Select boxes
<select id="gate"></select>
$("#gate option[value='Gateway 2']").attr("selected", true);
For text inputs
<input type="text" id="gate" />
$("#gate").attr("value", "your desired value")
For textarea inputs
<textarea id="gate"></textarea>
$("#gate").html("your desired value")
For checkbox boxes
<input type="checkbox" id="gate" />
$("#gate option[value='Gateway 2']").attr("checked", true);
For radio buttons
<input type="radio" id="gate" value="this"/> or <input type="radio" id="gate" value="that"/>
$("#gate[value='this']").attr("checked", true);

We got below error for Asp.Net MVC, Unable to connect to the remote server

I don't know if this was "the" official use case, but the following produces a warning in Java (that can further produce compile errors if mixed with return
statements, leading to unreachable code):
while (1 == 2) { // Note that "if" is treated differently
System.out.println("Unreachable code");
}
However this is legal:
while (isUserAGoat()) {
System.out.println("Unreachable but determined at runtime, not at compile time");
}
So I often find myself writing a silly utility method for the quickest way to dummy out a code block, then in completing debugging find all calls to it, so provided the implementation doesn't change this can be used for that.
JLS points out if (false)
does not trigger "unreachable code" for the specific reason that this would break support for debug flags, i.e., basically this use case (h/t @auselen). (static final boolean DEBUG = false;
for instance).
I replaced while
for if
, producing a more obscure use case. I believe you can trip up your IDE, like Eclipse, with this behavior, but this edit is 4 years into the future, and I don't have an Eclipse environment to play with.
The problem mainly occurs after updating OS X to El Capitan (OS X 10.11) or macOS Sierra (macOS 10.12).
This is because of file permission issues with El Capitan’s or later macOS's new SIP process. Try changing the permissions for the /usr/local
directory:
$ sudo chown -R $(whoami):admin /usr/local
If it still doesn't work, use these steps inside a terminal session and everything will be fine:
cd /usr/local/Library/Homebrew
git reset --hard
git clean -df
brew update
This may be because homebrew is not updated.
All these answers are nice however when thinking about it....
Sometimes the most simple approach without sophistication will do the trick quicker and with no special functions.
We first set the arrays:
$arr1 = Array(
"cod" => ddd,
"denum" => ffffffffffffffff,
"descr" => ggggggg,
"cant" => 3
);
$arr2 = Array
(
"cod" => fff,
"denum" => dfgdfgdfgdfgdfg,
"descr" => dfgdfgdfgdfgdfg,
"cant" => 33
);
Then we add them to the new array :
$newArr[] = $arr1;
$newArr[] = $arr2;
Now lets see our new array with all the keys:
print_r($newArr);
There's no need for sql or special functions to build a new multi-dimensional array.... don't use a tank to get to where you can walk.
There's only one thing to consider when deciding whether to use an IDE or not, and that's whether it makes you more productive or not.
Short question so short answer :)
Following procedure helped me solve this issue but i don't know why.
Even if it seems to be the same query executing it did not throw this error
One possible reason would be the incorrect path of the activity in the Apps AndroidManifest.xml file. Register the activity with in your AndroidManifest.xml with full relative path like below.
<activity android:name="<full_path>.ActivityName" />
Create a scope property called selectedIndex, and an itemClicked function:
function MyController ($scope) {
$scope.collection = ["Item 1", "Item 2"];
$scope.selectedIndex = 0; // Whatever the default selected index is, use -1 for no selection
$scope.itemClicked = function ($index) {
$scope.selectedIndex = $index;
};
}
Then my template would look something like this:
<div>
<span ng-repeat="item in collection"
ng-class="{ 'selected-class-name': $index == selectedIndex }"
ng-click="itemClicked($index)"> {{ item }} </span>
</div>
Just for reference $index is a magic variable available within ng-repeat directives.
You can use this same sample within a directive and template as well.
Here is a working plnkr:
I was in a process of switching from one version control service to another and needed to clone all repositories including all branches, tags and history.
To achieve above I did next:
git push origin '*:*'
.sh script used to checkout all branches to local repository:
for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v master `; do
git branch --track ${branch#remotes/origin/} $branch
done
When doing;
a_file = open('E:\Python Win7-64-AMD 3.3\Test', encoding='utf-8')
...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.
Your other example though;
a_file = open('E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')
should work well if you just have the permission on a.txt
. You may want to use a raw (r
-prefixed) string though, to make sure your path does not contain any escape characters like \n
that will be translated to special characters.
a_file = open(r'E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')
You should be able to generate your own button code here: http://developers.facebook.com/docs/reference/plugins/like/
When doing pan_list.append(p.last)
you're doing an inplace operation, that is an operation that modifies the object and returns nothing (i.e. None
).
You should do something like this :
last_list=[]
if p.last_name==None or p.last_name=="":
pass
last_list.append(p.last) # Here I modify the last_list, no affectation
print last_list
There is an extension for Google Chrome browser - GLOC which works for public and private repos.
Counts the number of lines of code of a project from:
I believe this is what you were looking for:
class Expression {
protected $expression;
protected $result;
public function __construct($expression) {
$this->expression = $expression;
}
public function evaluate() {
$this->result = eval("return ".$this->expression.";");
return $this;
}
public function getResult() {
return $this->result;
}
}
class NegativeFinder {
protected $expressionObj;
public function __construct(Expression $expressionObj) {
$this->expressionObj = $expressionObj;
}
public function isItNegative() {
$result = $this->expressionObj->evaluate()->getResult();
if($this->hasMinusSign($result)) {
return true;
} else {
return false;
}
}
protected function hasMinusSign($value) {
return (substr(strval($value), 0, 1) == "-");
}
}
Usage:
$soldPrice = 1;
$boughtPrice = 2;
$negativeFinderObj = new NegativeFinder(new Expression("$soldPrice - $boughtPrice"));
echo ($negativeFinderObj->isItNegative()) ? "It is negative!" : "It is not negative :(";
Do however note that eval is a dangerous function, therefore use it only if you really, really need to find out if a number is negative.

If you are using iTerm this command will open a new tab:
osascript -e 'tell application "iTerm" to activate' -e 'tell application "System Events" to tell process "iTerm" to keystroke "t" using command down'
There doesn't seem to be a standardized default value. I have the feeling the default is 0
, and the timeout event left totally dependent on browser and network settings.
For IE, there is a timeout property for XMLHTTPRequests here. It defaults to null, and it says the network stack is likely to be the first to time out (which will not generate an ontimeout event by the way).
Use -I
in grep.
Example: grep SEARCH_ME -Irs ~/logs
.
ESP
is the current stack pointer, which will change any time a word or address is pushed or popped onto/off off the stack. EBP
is a more convenient way for the compiler to keep track of a function's parameters and local variables than using the ESP
directly.
Generally (and this may vary from compiler to compiler), all of the arguments to a function being called are pushed onto the stack by the calling function (usually in the reverse order that they're declared in the function prototype, but this varies). Then the function is called, which pushes the return address (EIP
) onto the stack.
Upon entry to the function, the old EBP
value is pushed onto the stack and EBP
is set to the value of ESP
. Then the ESP
is decremented (because the stack grows downward in memory) to allocate space for the function's local variables and temporaries. From that point on, during the execution of the function, the arguments to the function are located on the stack at positive offsets from EBP
(because they were pushed prior to the function call), and the local variables are located at negative offsets from EBP
(because they were allocated on the stack after the function entry). That's why the EBP
is called the Frame Pointer, because it points to the center of the function call frame.
Upon exit, all the function has to do is set ESP
to the value of EBP
(which deallocates the local variables from the stack, and exposes the entry EBP
on the top of the stack), then pop the old EBP
value from the stack, and then the function returns (popping the return address into EIP
).
Upon returning back to the calling function, it can then increment ESP
in order to remove the function arguments it pushed onto the stack just prior to calling the other function. At this point, the stack is back in the same state it was in prior to invoking the called function.
There is no built-in method, but there are several ways to do it. The most straightforward way that I can think of at the moment is:
JComponent
.paintComponent(Graphics g)
method to paint the image that you want to display.JFrame
to be this subclass.Some sample code:
class ImagePanel extends JComponent {
private Image image;
public ImagePanel(Image image) {
this.image = image;
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image, 0, 0, this);
}
}
// elsewhere
BufferedImage myImage = ImageIO.read(...);
JFrame myJFrame = new JFrame("Image pane");
myJFrame.setContentPane(new ImagePanel(myImage));
Note that this code does not handle resizing the image to fit the JFrame
, if that's what you wanted.
No. Unlike other virtual methods, where you would explicitly call the Base method from the Derived to 'chain' the call, the compiler generates code to call the destructors in the reverse order in which their constructors were called.
@HostListener("window:resize", [])
public onResize() {
this.detectScreenSize();
}
public ngAfterViewInit() {
this.detectScreenSize();
}
private detectScreenSize() {
const height = window.innerHeight;
const width = window.innerWidth;
}
I do it this way when there are many points to use...
public enum Status {
VALID("valid"), OLD("old");
private final String val;
Status(String val) {
this.val = val;
}
public String getStatus() {
return val;
}
public static void setRequestAttributes(HttpServletRequest request) {
Map<String,String> vals = new HashMap<String,String>();
for (Status val : Status.values()) {
vals.put(val.name(), val.value);
}
request.setAttribute("Status", vals);
}
}

All C++ compilers have one serious performance problem to deal with. Compiling C++ code is a long, slow process.
Compiling headers included on top of C++ files is a very long, slow process. Compiling the huge header structures that form part of Windows API and other large API libraries is a very, very long, slow process. To have to do it over, and over, and over for every single Cpp source file is a death knell.
This is not unique to Windows but an old problem faced by all compilers that have to compile against a large API like Windows.
The Microsoft compiler can ameliorate this problem with a simple trick called precompiled headers. The trick is pretty slick: although every CPP file can potentially and legally give a sligthly different meaning to the chain of header files included on top of each Cpp file (by things like having different macros #define'd in advance of the includes, or by including the headers in different order), that is most often not the case. Most of the time, we have dozens or hundreds of included files, but they all are intended to have the same meaning for all the Cpp files being compiled in your application.
The compiler can make huge time savings if it doesn't have to start to compile every Cpp file plus its dozens of includes literally from scratch every time.
The trick consists of designating a special header file as the starting point of all compilation chains, the so called 'precompiled header' file, which is commonly a file named stdafx.h simply for historical reasons.
Simply list all your big huge headers for your APIs in your stdafx.h file, in the appropriate order, and then start each of your CPP files at the very top with an #include "stdafx.h"
, before any meaningful content (just about the only thing allowed before is comments).
Under those conditions, instead of starting from scratch, the compiler starts compiling from the already saved results of compiling everything in stdafx.h
.
I don't believe that this trick is unique to Microsoft compilers, nor do I think it was an original development.
For Microsoft compilers, the setting that controls the use of precompiled headers is controlled by a command line argument to the compiler: /Yu "stdafx.h"
. As you can imagine, the use of the stdafx.h
file name is simply a convention; you can change the name if you so wish.
In Visual Studio 2010, this setting is controlled from the GUI via Right-clicking on a CPP Project, selecting 'Properties' and navigating to "Configuration Properties\C/C++\Precompiled Headers". For other versions of Visual Studio, the location in the GUI will be different.
Note that if you disable precompiled headers (or run your project through a tool that doesn't support them), it doesn't make your program illegal; it simply means that your tool will compile everything from scratch every time.
If you are creating a library with no Windows dependencies, you can easily comment out or remove #include
s from the stdafx.h
file. There is no need to remove the file per se, but clearly you may do so as well, by disabling the precompile header setting above.
I was facing same problem.Tried every think mentioned here in blog.
But it was basic error to permit device "allow installing app from USB" which did it for me.
I've used this code before to create a simple timespan object:
function TimeSpan(time) {
this.hours = 0;
this.minutes = 0;
this.seconds = 0;
while(time >= 3600)
{
this.hours++;
time -= 3600;
}
while(time >= 60)
{
this.minutes++;
time -= 60;
}
this.seconds = time;
}
var timespan = new Timespan(3662);
It has to do with how the function is called- basically the order in which things are put on the the stack and who is responsible for cleanup.
Here's the documentation, but it doesn't mean much unless you understand the first part:

You change default value in MySQL configuration file (option connect_timeout in mysqld section) -
[mysqld]
connect_timeout=100
If this file is not accessible for you, then you can set this value using this statement -
SET GLOBAL connect_timeout=100;
You can try a list comp
>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
Another way is by using filter
>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
function getMeta(url){
$("<img/>",{
load : function(){

});
}
function getMeta(url){
var img = new Image();
img.onload = function(){
alert( this.width+' '+ this.height );
};
img.src = url;
}
function getMeta(url){
var img = new Image();
img.addEventListener("load", function(){
alert( this.naturalWidth +' '+ this.naturalHeight );
});
img.src = url;
}
Use the above simply as: getMeta( "http://example.com/img.jpg" );

I found this question as I had a similar problem. While data-backdrop
does "solve" the issue; I found another problem in my markup.
I had the button which launched this modal and the modal dialog itself was in the footer. The problem is that the footer was defined as navbar_fixed_bottom
, and that contained position:fixed
.
After I moved the dialog outside of the fixed section, everything worked as expected.
I went ahead and implemented greybeard suggestion in the comments. Mostly because I needed a highly efficient mission critical version of this code.
This should be the most efficient way to do this, with time complexity of O(log(n)*log(i)) rather than O(n). And worst case time complexity of O(n). If your arrays are clumpy and have long strings of values together, this will dwarf any other way to do it, otherwise it'll just be better than them.
It has two read values at the ends of the merging array and the write value within the results array. After finding out which is end value is less, it does a gallop search into that array. 1, 2, 4, 8, 16, 32, etc. When it finds the range where the the other array's read value is bigger. It binary searches into that range (cuts the range in half, search the correct half, repeat until single value). Then it array copies those values into the write position. Keeping in mind that the copy is, by necessity, moved such that it cannot overwrite the same values from the either reading array (which means the write array and read array can be the same). It then performs the same operation for the other array which is now known to be less than the new read value of the other array.
static public int gallopSearch(int current, int[] array, int v) {
int d = 1;
int seek = current - d;
int prevIteration = seek;
while (seek > 0) {
if (Integer.compare(array[seek], v) <= 0) {
break;
}
prevIteration = seek;
d <<= 1;
seek = current - d;
if (seek < 0) {
seek = 0;
}
}
if (prevIteration != seek) {
seek = binarySearch(array, seek, prevIteration, v);
seek = seek >= 0 ? seek : ~seek;
}
return seek;
}
static public int binarySearch(int[] list, int fromIndex, int toIndex, int v) {
int low = fromIndex;
int high = toIndex - 1;

if (cmp < 0) {
low = mid + 1;
} else if (cmp > 0) {
high = mid - 1;
} else {
return mid;// key found
}
}
return -(low + 1);// key not found.
}
static public int[] sortedArrayMerge(int[] a, int[] b) {
return sortedArrayMerge(null, a, a.length, b, b.length);
}
static public int[] sortedArrayMerge(int[] results, int[] a, int aRead, int b[], int bRead) {
int write = aRead + bRead, length, gallopPos;
if ((results == null) || (results.length < write)) {
results = new int[write];
}
if (aRead > 0 && bRead > 0) {
int c = Integer.compare(a[aRead - 1], b[bRead - 1]);
while (aRead > 0 && bRead > 0) {
switch (c) {
default:
gallopPos = gallopSearch(aRead, a, b[bRead-1]);
length = (aRead - gallopPos);
write -= length;
aRead = gallopPos;
System.arraycopy(a, gallopPos--, results, write, length);
c = -1;
break;
case -1:
gallopPos = gallopSearch(bRead, b, a[aRead-1]);
length = (bRead - gallopPos);
write -= length;
bRead = gallopPos;
System.arraycopy(b, gallopPos--, results, write, length);
c = 1;
break;
}
}
}
if (bRead > 0) {
if (b != results) {
System.arraycopy(b, 0, results, 0, bRead);
}
} else if (aRead > 0) {
if (a != results) {
System.arraycopy(a, 0, results, 0, aRead);
}
}
return results;
}
This should be the most efficient way to do it.
Some answers had a duplicate remove ability. That'll require an O(n) algorithm because you must actually compare each item. So here's a stand-alone for that, to be applied after the fact. You can't gallop through multiple entries all the way through if you need to look at all of them, though you could gallop through the duplicates, if you had a lot of them.
static public int removeDuplicates(int[] list, int size) {
int write = 1;
for (int read = 1; read < size; read++) {
if (list[read] == list[read - 1]) {
continue;
}
list[write++] = list[read];
}
return write;
}
Update: Previous answer, not horrible code but clearly inferior to the above.
Another needless hyper-optimization. It not only invokes arraycopy for the end bits, but also for the beginning. Processing any introductory non-overlap in O(log(n)) by a binarySearch into the data. O(log(n) + n) is O(n) and in some cases the effect will be pretty pronounced especially things like where there is no overlap between the merging arrays at all.
private static int binarySearch(int[] array, int low, int high, int v) {
high = high - 1;
while (low <= high) {
int mid = (low + high) >>> 1;
int midVal = array[mid];
if (midVal > v)
low = mid + 1;
else if (midVal < v)
high = mid - 1;
else
return mid; // key found
}
return low;//traditionally, -(low + 1); // key not found.
}
private static int[] sortedArrayMerge(int a[], int b[]) {
int result[] = new int[a.length + b.length];
int k, i = 0, j = 0;
if (a[0] > b[0]) {
k = i = binarySearch(b, 0, b.length, a[0]);
System.arraycopy(b, 0, result, 0, i);
} else {
k = j = binarySearch(a, 0, a.length, b[0]);
System.arraycopy(a, 0, result, 0, j);
}
while (i < a.length && j < b.length) {
result[k++] = (a[i] < b[j]) ? a[i++] : b[j++];
}
if (j < b.length) {
System.arraycopy(b, j, result, k, (b.length - j));
} else {
System.arraycopy(a, i, result, k, (a.length - i));
}
return result;
}
Python (until version 3) supports "old-style" and new-style classes. New-style classes are derived from object
and are what you are using, and invoke their base class through super()
, e.g.
class X(object):
def __init__(self, x):
pass
def doit(self, bar):
pass
class Y(X):
def __init__(self):
super(Y, self).__init__(123)
def doit(self, foo):
return super(Y, self).doit(foo)
Because python knows about old- and new-style classes, there are different ways to invoke a base method, which is why you've found multiple ways of doing so.
For completeness sake, old-style classes call base methods explicitly using the base class, i.e.
def doit(self, foo):
return X.doit(self, foo)
But since you shouldn't be using old-style anymore, I wouldn't care about this too much.
Python 3 only knows about new-style classes (no matter if you derive from object
or not).
There are two issues here.
Firstly, you can't use the []
syntax like you may be able to in other languages. Square brackets only apply to arrays in Java, and so can only be used with integer indexes.
data.put
is correct but that is a statement and so must exist in a method block. Only field declarations can exist at the class level. Here is an example where everything is within the local scope of a method:
public class Data {
public static void main(String[] args) {
Map<String, String> data = new HashMap<String, String>();
data.put("John", "Taxi Driver");
data.put("Mark", "Professional Killer");
}
}
If you want to initialize a map as a static field of a class then you can use Map.of
, since Java 9:
public class Data {
private static final Map<String, String> DATA = Map.of("John", "Taxi Driver");
}
Before Java 9, you can use a static initializer block to accomplish the same thing:
public class Data {
private static final Map<String, String> DATA = new HashMap<>();
static {
DATA.put("John", "Taxi Driver");
}
}
If you need to have control over the format of the date (in other words not just the yyyy-mm-dd format is acceptable), another solution could be adding a helper property that is of type string and add a date validator to that property, and bind to this property on UI.
[Display(Name = "Due date")]
[Required]
[AllowHtml]
[DateValidation]
public string DueDateString { get; set; }
public DateTime? DueDate
{
get
{
return string.IsNullOrEmpty(DueDateString) ? (DateTime?)null : DateTime.Parse(DueDateString);
}
set
{
DueDateString = value == null ? null : value.Value.ToString("d");
}
}
And here is a date validator:
[AttributeUsage(AttributeTargets.Property, AllowMultiple = true, Inherited = true)]
public class DateValidationAttribute : ValidationAttribute
{
public DateValidationAttribute()
{
}
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
if (value != null)
{
DateTime date;
if (value is string)
{
if (!DateTime.TryParse((string)value, out date))
{
return new ValidationResult(validationContext.DisplayName + " must be a valid date.");
}
}
else
date = (DateTime)value;
if (date < new DateTime(1900, 1, 1) || date > new DateTime(3000, 12, 31))
{
return new ValidationResult(validationContext.DisplayName + " must be a valid date.");
}
}
return null;
}
}
I experienced this error when using bindParam, and specifying PDO::PARAM_INT where I was actually passing a string. Changing to PDO::PARAM_STR fixed the error.
There are two ways to set this up. If you have an SID, use this (older) format:
jdbc:oracle:thin:@[HOST][:PORT]:SID
If you have an Oracle service name, use this (newer) format:
jdbc:oracle:thin:@//[HOST][:PORT]/SERVICE
Source: this OraFAQ page
The call to getConnection()
is correct.
Also, as duffymo said, make sure the actual driver code is present by including ojdbc6.jar
in the classpath, where the number corresponds to the Java version you're using.
I have taken an empty dictionary as f and updated the values in f as name,password or balance are keys.
f=dict()
f.update(name=input(),password=input(),balance=input())
print(f)
To use uint8_t
type alias, you have to include stdint.h
standard header.
Maven needs the dependencies in your local repository. The easiest way to get them is with internet access (or harder using other solutions provided here).
So assumed that you can get temporarily internet access you can prepare to go offline using the maven-dependency-plugin with its dependency:go-offline goal. This will download all your project dependencies to your local repository (of course changes in the dependencies / plugins will require new internet / central repository access).
Google is depreciating C2DM, but in its place their introducing GCM (Google Cloud Messaging) I dont think theirs any quota and its free! It does require Android 2.2+ though! http://developer.android.com/guide/google/gcm/index.html
This is an old question, but because this might help a lot of c# coders out there, there is an easy way to solve this right now as follows:
if ((dataTableName?.Rows?.Count ?? 0) > 0)
in KotlinDSL you can use like this :
flavorDimensions ("PlaceApp")
productFlavors {
create("tapsi") {
setDimension("PlaceApp")
buildConfigField("String", "API_BASE_URL", "https://xxx/x/x/")
}
}
i uses Js function replace simply.
<Text>{item.excerpt.rendered.replace(/<\/?[^>]+(>|$)/g, "")}</Text>
For a portable (ISO C90) implementation, you could use double parentheses, like this;
#include <stdio.h>
#include <stdarg.h>
#ifndef NDEBUG
# define debug_print(msg) stderr_printf msg
#else
# define debug_print(msg) (void)0
#endif
void
stderr_printf(const char *fmt, ...)
{
va_list ap;
va_start(ap, fmt);
vfprintf(stderr, fmt, ap);
va_end(ap);
}
int
main(int argc, char *argv[])
{
debug_print(("argv[0] is %s, argc is %d\n", argv[0], argc));
return 0;
}
or (hackish, wouldn't recommend it)
#include <stdio.h>
#define _ ,
#ifndef NDEBUG
# define debug_print(msg) fprintf(stderr, msg)
#else
# define debug_print(msg) (void)0
#endif
int
main(int argc, char *argv[])
{
debug_print("argv[0] is %s, argc is %d"_ argv[0] _ argc);
return 0;
}
tree -L 2 -u -g -p -d
Prints the directory tree in a pretty format up to depth 2 (-L 2). Print user (-u) and group (-g) and permissions (-p). Print only directories (-d). tree has a lot of other useful options.
This depends on where you want the error message be stored.
You can do the following:
echo "Error!" > logfile.log
exit 125
Or the following:
echo "Error!" 1>&2
exit 64
When you raise an exception you stop the program's execution.
You can also use something like exit xxx
where xxx
is the error code you may want to return to the operating system (from 0 to 255). Here 125
and 64
are just random codes you can exit with. When you need to indicate to the OS that the program stopped abnormally (eg. an error occurred), you need to pass a non-zero exit code to exit
.
As @chepner pointed out, you can do exit 1
, which will mean an unspecified error.
For completeness, using cut
cut -d : -f 2 <<< $var
And using only bash:
IFS=: read a b <<< $var ; echo $b
One simple thing you could do is abstract the test inside a function.
local function isempty(s)
return s == nil or s == ''
end
if isempty(foo) then
foo = "default value"
end
As drawn from http://php.net/ && Chipmunkninja:
The system() Function
The system function in PHP takes a string argument with the command to execute as well as any arguments you wish passed to that command. This function executes the specified command, and dumps any resulting text to the output stream (either the HTTP output in a web server situation, or the console if you are running PHP as a command line tool). The return of this function is the last line of output from the program, if it emits text output.
The exec() Function
The system function is quite useful and powerful, but one of the biggest problems with it is that all resulting text from the program goes directly to the output stream. There will be situations where you might like to format the resulting text and display it in some different way, or not display it at all.
For this, the exec function in PHP is perfectly adapted. Instead of automatically dumping all text generated by the program being executed to the output stream, it gives you the opportunity to put this text in an array returned in the second parameter to the function:
The shell_exec() Function
Most of the programs we have been executing thus far have been, more or less, real programs1. However, the environment in which Windows and Unix users operate is actually much richer than this. Windows users have the option of using the Windows Command Prompt program, cmd.exe This program is known as a command shell.
The passthru() Function
One fascinating function that PHP provides similar to those we have seen so far is the passthru function. This function, like the others, executes the program you tell it to. However, it then proceeds to immediately send the raw output from this program to the output stream with which PHP is currently working (i.e. either HTTP in a web server scenario, or the shell in a command line version of PHP).
The proc_open() Function and popen() function
proc_open() is similar to popen() but provides a much greater degree of control over the program execution. cmd is the command to be executed by the shell. descriptorspec is an indexed array where the key represents the descriptor number and the value represents how PHP will pass that descriptor to the child process. pipes will be set to an indexed array of file pointers that correspond to PHP's end of any pipes that are created. The return value is a resource representing the process; you should free it using proc_close() when you are finished with it.
You need good starting values such that the curve_fit
function converges at "good" values. I can not really say why your fit did not converge (even though the definition of your mean is strange - check below) but I will give you a strategy that works for non-normalized Gaussian-functions like your one.
The estimated parameters should be close to the final values (use the weighted arithmetic mean - divide by the sum of all values):
import matplotlib.pyplot as plt
from scipy.optimize import curve_fit
import numpy as np
x = np.arange(10)
y = np.array([0, 1, 2, 3, 4, 5, 4, 3, 2, 1])
# weighted arithmetic mean (corrected - check the section below)
mean = sum(x * y) / sum(y)
sigma = np.sqrt(sum(y * (x - mean)**2) / sum(y))
def Gauss(x, a, x0, sigma):
return a * np.exp(-(x - x0)**2 / (2 * sigma**2))
popt,pcov = curve_fit(Gauss, x, y, p0=[max(y), mean, sigma])
plt.plot(x, y, 'b+:', label='data')
plt.plot(x, Gauss(x, *popt), 'r-', label='fit')
plt.legend()
plt.title('Fig. 3 - Fit for Time Constant')
plt.xlabel('Time (s)')
plt.ylabel('Voltage (V)')
plt.show()
I personally prefer using numpy.
Since the reviewers did not like my edit on #Developer's code, I will explain for what case I would suggest an improved code. The mean of developer does not correspond to one of the normal definitions of the mean.
Your definition returns:
>>> sum(x * y)
125
Developer's definition returns:
>>> sum(x * y) / len(x)
12.5 #for Python 3.x
The weighted arithmetic mean:
>>> sum(x * y) / sum(y)
5.0
Similarly you can compare the definitions of standard deviation (sigma
). Compare with the figure of the resulting fit:
In Python 2.x you should additionally use the new division to not run into weird results or convert the the numbers before the division explicitly:
from __future__ import division
or e.g.
sum(x * y) * 1. / sum(y)
I use this
var e = document.getElementById('ticket_category_clone').value;
Notice that you don't need the '#' character in javascript.
function check () {
var str = document.getElementById('ticket_category_clone').value;
if (str==="Hardware")
{
SPICEWORKS.utils.addStyle('#ticket_c_hardware_clone{display: none !important;}');
}
}
SPICEWORKS.app.helpdesk.ready(check);?
dataGridView1.Columns
is probably of a length less than 5. Accessing dataGridView1.Columns[4]
then will be outside the list.
You can use array.slice(0,1) // First index is removed and array is returned.
inlace sort
def qsort(a, b=0, e=None):
# partitioning
def part(a, start, end):
p = start
for i in xrange(start+1, end):
if a[i] < a[p]:
a[i], a[p+1] = a[p+1], a[i]
a[p+1], a[p] = a[p], a[p+1]
p += 1
return p
if e is None:
e = len(a)
if e-b <= 1: return
p = part(a, b, e)
qsort(a, b, p)
qsort(a, p+1, e)
without recursion:
deq = collections.deque()
deq.append((b, e))
while len(deq):
el = deq.pop()
if el[1] - el[0] > 1:
p = part(a, el[0], el[1])
deq.append((el[0], p))
deq.append((p+1, el[1]))
test
is a non-destructive and
, it doesn't return the result of the operation but it sets the flags register accordingly. To know what it really tests for you need to check the following instruction(s). Often out is used to check a register against 0, possibly coupled with a jz
conditional jump.

Use the modulo operator:
if wordLength % 2 == 0:
print "wordLength is even"
else:
print "wordLength is odd"
For your problem, the simplest is to check if the word is equal to its reversed brother. You can do that with word[::-1]
, which create the list from word
by taking every character from the end to the start:
def is_palindrome(word):
return word == word[::-1]
As root on CentOS 7:
systemctl start memcached
systemctl stop memcached
systemctl restart memcached
To tell the service to start at reboot (ex chkconfig):
systemctl enable memcached
To tell the service to not start at reboot:
systemctl disable memcached
Another valid option is to spread the joins across multiple LINQ clauses, as follows:
public static IEnumerable<Announcementboard> GetSiteContent(string pageName, DateTime date)
{
IEnumerable<Announcementboard> content = null;
IEnumerable<Announcementboard> addMoreContent = null;
try
{
content = from c in DB.Announcementboards
// Can be displayed beginning on this date
where c.Displayondate > date.AddDays(-1)
// Doesn't Expire or Expires at future date
&& (c.Displaythrudate == null || c.Displaythrudate > date)
// Content is NOT draft, and IS published
&& c.Isdraft == "N" && c.Publishedon != null
orderby c.Sortorder ascending, c.Heading ascending
select c;
// Get the content specific to page names
if (!string.IsNullOrEmpty(pageName))
{
addMoreContent = from c in content
join p in DB.Announceonpages on c.Announcementid equals p.Announcementid
join s in DB.Apppagenames on p.Apppagenameid equals s.Apppagenameid
where s.Apppageref.ToLower() == pageName.ToLower()
select c;
}
// Add the specified content using UNION
content = content.Union(addMoreContent);
// Exclude the duplicates using DISTINCT
content = content.Distinct();
return content;
}
catch (MyLovelyException ex)
{
// Add your exception handling here
throw ex;
}
}
Using alias can be time-saving
alias myDir = "cd /this/is/a/long/directory; pwd"

I was looking forward this for a long time, and found no simple working example, but based on these answers I created the downloadAndUnzip()
function.
The usage is quite simple:
downloadAndUnzip('http://your-domain.com/archive.zip', 'yourfile.xml')
.then(function (data) {
console.log(data); // unzipped content of yourfile.xml in root of archive.zip
})
.catch(function (err) {
console.error(err);
});
And here is the declaration:
var AdmZip = require('adm-zip');
var request = require('request');
var downloadAndUnzip = function (url, fileName) {
/**
* Download a file
*
* @param url
*/
var download = function (url) {
return new Promise(function (resolve, reject) {
request({
url: url,
method: 'GET',
encoding: null
}, function (err, response, body) {
if (err) {
return reject(err);
}
resolve(body);
});
});
};
/**
* Unzip a Buffer
*
* @param buffer
* @returns {Promise}
*/
var unzip = function (buffer) {
return new Promise(function (resolve, reject) {
var resolved = false;
var zip = new AdmZip(buffer);
var zipEntries = zip.getEntries(); // an array of ZipEntry records
zipEntries.forEach(function (zipEntry) {
if (zipEntry.entryName == fileName) {
resolved = true;
resolve(zipEntry.getData().toString('utf8'));
}
});
if (!resolved) {
reject(new Error('No file found in archive: ' + fileName));
}
});
};
return download(url)
.then(unzip);
};
$('.class').length
This one does not work for me. I'd rather use this:
$('.class').children().length
I don't really know the reason why, but the second one works only for me. Somewhy, either size doesn't work.

For Angular 5+ only preform steps 1 and 4
In order to access your file locally in Angular 2+ you should do the following (4 steps):
[1] Inside your assets folder create a .json file, example: data.json
[2] Go to your angular.cli.json (angular.json in Angular 6+) inside your project and inside the assets array put another object (after the package.json object) like this:
{ "glob": "data.json", "input": "./", "output": "./assets/" }
full example from angular.cli.json
"apps": [
{
"root": "src",
"outDir": "dist",
"assets": [
"assets",
"favicon.ico",
{ "glob": "package.json", "input": "../", "output": "./assets/" },
{ "glob": "data.json", "input": "./", "output": "./assets/" }
],
Remember, data.json is just the example file we've previously added in the assets folder (you can name your file whatever you want to)
[3] Try to access your file via localhost. It should be visible within this address, http://localhost:your_port/assets/data.json
If it's not visible then you've done something incorrectly. Make sure you can access it by typing it in the URL field in your browser before proceeding to step #4.
[4] Now preform a GET request to retrieve your .json file (you've got your full path .json URL and it should be simple)
constructor(private http: HttpClient) {}
// Make the HTTP request:
this.http.get('http://localhost:port/assets/data.json')
.subscribe(data => console.log(data));
Here is my class for checking if a string is numeric. It also fixes numerical strings:
Here you go...
public class NumUtils {
/**

static String makeToInteger(String str) {
String s = str;
double d;
d = Double.parseDouble(makeToDouble(s));
int i = (int) (d + 0.5D);
String retStr = String.valueOf(i);
System.out.printf(retStr + " ");
return retStr;
}
/**
* Transforms a string to an double. If no numerical chars returns a String "0".
*
* @param str
* @return retStr
*/
static String makeToDouble(String str) {
Boolean dotWasFound = false;
String orgStr = str;
String retStr;
int firstDotPos = 0;
Boolean negative = false;
//check if str is null
if(str.length()==0){
str="0";
}
//check if first sign is "-"
if (str.charAt(0) == '-') {
negative = true;
}
//check if str containg any number or else set the string to '0'
if (!str.matches(".*\\d+.*")) {
str = "0";
}
//Replace ',' with '.' (for some european users who use the ',' as decimal separator)
str = str.replaceAll(",", ".");
str = str.replaceAll("[^\\d.]", "");
//Removes the any second dots
for (int i_char = 0; i_char < str.length(); i_char++) {
if (str.charAt(i_char) == '.') {
dotWasFound = true;
firstDotPos = i_char;
break;
}
}
if (dotWasFound) {
String befDot = str.substring(0, firstDotPos + 1);
String aftDot = str.substring(firstDotPos + 1, str.length());
aftDot = aftDot.replaceAll("\\.", "");
str = befDot + aftDot;
}
//Removes zeros from the begining
double uglyMethod = Double.parseDouble(str);
str = String.valueOf(uglyMethod);
//Removes the .0
str = str.replaceAll("([0-9])\\.0+([^0-9]|$)", "$1$2");
retStr = str;
if (negative) {
retStr = "-"+retStr;
}
return retStr;
}
static boolean isNumeric(String str) {
try {
double d = Double.parseDouble(str);
} catch (NumberFormatException nfe) {
return false;
}

One of the dummies ways to determine if .NET Core
is installed on Windows is:
cmd
dotnet --version
If the .NET Core
is installed, we should not get any error in the above steps.
I have created a module for pipes in the same directory where my pipes are present
import { NgModule } from '@angular/core';
///import pipe...
import { Base64ToImage, TruncateString} from './'
@NgModule({
imports: [],
declarations: [Base64ToImage, TruncateString],
exports: [Base64ToImage, TruncateString]
})
export class SharedPipeModule { }
Now import that module in app.module:
import {SharedPipeModule} from './pipe/shared.pipe.module'
@NgModule({
imports: [
...
, PipeModule.forRoot()
....
],
Now it can be used by importing the same in the nested module
This is quite easy to do with your Apache environment variables. This only works with Apache 2, which I assume you are using.
Simply use the following PHP code:
<?php
$request_url = apache_getenv("HTTP_HOST") . apache_getenv("REQUEST_URI");
echo $request_url;
?>
Map:
Map transformation.
The map works on a single Row at a time.
Map returns after each input Row.
The map doesn’t hold the output result in Memory.
Map no way to figure out then to end the service.
// map example
val dfList = (1 to 100) toList
val df = dfList.toDF()
val dfInt = df.map(x => x.getInt(0)+2)
display(dfInt)
MapPartition:
MapPartition transformation.
MapPartition works on a partition at a time.
MapPartition returns after processing all the rows in the partition.
MapPartition output is retained in memory, as it can return after processing all the rows in a particular partition.
MapPartition service can be shut down before returning.
// MapPartition example
Val dfList = (1 to 100) toList
Val df = dfList.toDF()
Val df1 = df.repartition(4).rdd.mapPartition((int) => Iterator(itr.length))
Df1.collec()
//display(df1.collect())
For more details, please refer to the Spark map vs mapPartitions transformation article.
Hope this is helpful!
The code can be cleaned up, but if you are using a list to store your tuples, any such lookup will be O(N).
If lookup speed is important, you should use a dict
to store your tuples. The key should be the 0th element of your tuples, since that's what you're searching on. You can easily create a dict from your list:
my_dict = dict(my_list)
Then, (VALUE, my_dict[VALUE])
will give you your matching tuple (assuming VALUE
exists).
Use git reset:
git reset --hard "Version 1.0 Revision 1.5"
(assuming that the specified string is the tag).
You can use below command if you want to print entire line and file name if the occurrence of particular word in current directory you are searching.
grep -m 1 -r "Not caching" * | head -1
REST vs. SOAP
SOAP:
? SOAP is simple object access protocol that run on TCP/UDP/SMTP.
? SOAP read and write request response messages in XML format.
? SOAP uses interface in order to define the services.
? SOAP is more secure as it has its own security and well defined standards.
? SOAP follows RPC and Document style to define web services.
? SOAP uses SOAP-UI as client tools for testing.
REST
? REST is representational state transfer that uses underlying HTTP protocols.
? REST is stateless.
? REST is an architectural style that is used to describe and define web services.
? REST can read and write request response messages in JSON/XML/Plain HTML.
? REST uses URI for each resource that is used in web service.A resource can be image text method etc.
? REST uses set of verbs, like HTTP's GET, POST, PUT, DELETE.
? REST is easy to develop and easy to manage as compared to SOAP UI.
? REST has light-weight client tools or plugins that can easily be integrated inside a browser.
? REST services are cacheable.
I have a library that is doing exactly you need.
Some time ago I had wrote simple and fast enough library for work with CSV files. You can find it by the following link: https://github.com/ukushu/DataExporter
It works with CSV like with 2 dimensions array. Exactly like you need.
As example, in case of you need all of values of 3rd row only you need is to write:
Csv csv = new Csv();
csv.FileOpen("c:\\file1.csv");
var allValuesOf3rdRow = csv.Rows[2];
or to read 2nd cell of
var value = csv.Rows[2][1];
Apostrophes in the strings.xml should be written as
\'
In my case I had an error with this string in my strings.xml and I fixed it.
<item>Most arguments can be ended with three words, "I don\'t care".</item>
Here you see my app builds properly with that code.
Here is the actual string in my app.
Update:
There is now the possibility to use prefix
to get the first n elements of an array. Check @mluisbrown's answer for an explanation how to use prefix.
Original Answer:
You can do it really easy without filter
, map
or reduce
by just returning a range of your array:
var wholeArray = [1, 2, 3, 4, 5, 6]
var n = 5
var firstFive = wholeArray[0..<n] // 1,2,3,4,5
I created an arrayList from it and I somehow can't find a way to store this information into a JTable.
The DefaultTableModel doesn't support displaying custom Objects stored in an ArrayList. You need to create a custom TableModel.
You can check out the Bean Table Model. It is a reusable class that will use reflection to find all the data in your FootballClub class and display in a JTable.
Or, you can extend the Row Table Model
found in the above link to make is easier to create your own custom TableModel by implementing a few methods. The JButtomTableModel.java
source code give a complete example of how you can do this.
I know how this can be done using
fgets
andstrtol
, I would like to know how this can be done usingscanf()
(if possible).
As the other answers say, scanf
isn't really suitable for this, fgets
and strtol
is an alternative (though fgets
has the drawback that it's hard to detect a 0-byte in the input and impossible to tell what has been input after a 0-byte, if any).
For sake of completeness (and assuming valid input is an integer followed by a newline):
while(scanf("%d%1[\n]", &n, (char [2]){ 0 }) < 2)
Alternatively, use %n
before and after %*1[\n]
with assignment-suppression. Note, however (from the Debian manpage):
This is not a conversion, although it can be suppressed with the
*
assignment-suppression character. The C standard says: "Execution of a%n
directive does not increment the assignment count returned at the completion of execution" but the Corrigendum seems to contradict this. Probably it is wise not to make any assumptions on the effect of%n
conversions on the return value.
Using the credentials helper command-line option:
git -c credential.helper='!f() { echo "password=mysecretpassword"; }; f' fetch origin
<form action="display.html" method="post">_x000D_
<input type="text" name="serialNumber" />_x000D_
<input type="submit" value="Submit" />_x000D_
</form>
_x000D_
In display.html you should add the following code.
<script>
function getParameterByName(name, url) {
if (!url) url = window.location.href;
name = name.replace(/[\[\]]/g, '\\$&');
var regex = new RegExp('[?&]' + name + '(=([^&#]*)|&|#|$)'),
results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, ' '));
}
var sn = getParameterByName('serialNumber');
document.getElementById("write").innerHTML = sn;
</script>
In your case, "EOF" is known as a "Here Tag". Basically <<Here
tells the shell that you are going to enter a multiline string until the "tag" Here
. You can name this tag as you want, it's often EOF
or STOP
.
Some rules about the Here tags:
example:
$ cat >> test <<HERE
> Hello world HERE <-- Not by itself on a separate line -> not considered end of string
> This is a test
> HERE <-- Leading space, so not considered end of string
> and a new line
> HERE <-- Now we have the end of the string
Got the same problem, found the following bug report in SQL Server 2012 If still relevant see conditions that cause the issue - there are some workarounds there as well (didn't try though). Failover or Restart Results in Reseed of Identity
I separate it, and then use an identity comparison to dictate what is does next.
$("#selectField").change(function(){
if(this.value === 'textValue1'){ $(".contentClass1").fadeIn(); }
if(this.value === 'textValue2'){ $(".contentclass2").fadeIn(); }
});
Sub Datainput()
'Checkbox values are 0 (false), 1 (true), 2 (changed or grey)
If activesheet.CheckBoxes("Check Box 1").value = 1 then
Msgbox ("Yay")
Else: Msgbox("Aww")
End if
End Sub
In my case I had something like cURL Error (7): ... Operation Timed Out
. I'm using the network connection of the company I'm working for. I needed to create some environment variables. The next worked for me:
In Linux terminal:
$ export https_proxy=yourProxy:80
$ export http_proxy=yourProxy:80
In windows I created (the same) environment variables in the windows way.
I hope it helps!
Regards!

# Make a set of your "types":
input_set = set([tpl[1] for tpl in input])
>>> set(['ETH', 'KAT', 'NOT'])
# Iterate over the input_set
for type_ in input_set:
# a dict to gather things:
D = {}
# filter all tuples from your input with the same type as type_
tuples = filter(lambda tpl: tpl[1] == type_, input)
# write them in the D:
D["type"] = type_
D["itmes"] = [tpl[0] for tpl in tuples]
# append D to results:
result.append(D)

For Swift 5:
extension String {
var htmlToAttributedString: NSAttributedString? {
guard let data = data(using: .utf8) else { return nil }
do {
return try NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding:String.Encoding.utf8.rawValue], documentAttributes: nil)
} catch {
return nil
}
}
var htmlToString: String {
return htmlToAttributedString?.string ?? ""
}
}
Then, whenever you want to put HTML text in a UITextView use:
textView.attributedText = htmlText.htmlToAttributedString
Well I write a script which works very well.

If choosing between OAuth versions, go with OAuth 2.0.
OAuth bearer tokens should only be used with a secure transport.
OAuth bearer tokens are only as secure or insecure as the transport that encrypts the conversation. HTTPS takes care of protecting against replay attacks, so it isn't necessary for the bearer token to also guard against replay.
While it is true that if someone intercepts your bearer token they can impersonate you when calling the API, there are plenty of ways to mitigate that risk. If you give your tokens a long expiration period and expect your clients to store the tokens locally, you have a greater risk of tokens being intercepted and misused than if you give your tokens a short expiration, require clients to acquire new tokens for every session, and advise clients not to persist tokens.
If you need to secure payloads that pass through multiple participants, then you need something more than HTTPS/SSL, since HTTPS/SSL only encrypts one link of the graph. This is not a fault of OAuth.
Bearer tokens are easy to for clients to obtain, easy for clients to use for API calls and are widely used (with HTTPS) to secure public facing APIs from Google, Facebook, and many other services.

You could try writing the XDocument to an XmlWriter piped to an XmlReader for an XmlDocument.
If I understand the concepts properly, a direct conversion is not possible (the internal structure is different / simplified with XDocument). But then, I might be wrong...
In simple words:
var x = (day == "yes") ? "Good Day!" : (day == "no") ? "Good Night!" : "";
By default you can't use PHP in HTML pages.
To do that, modify your .htacccess file with the following:
AddType application/x-httpd-php .html
e
is the short var reference for event
object which will be passed to event handlers.
The event object essentially has lot of interesting methods and properties that can be used in the event handlers.
In the example you have posted is a click handler which is a MouseEvent
$(<element selector>).click(function(e) {
// does something
alert(e.type); //will return you click
}
DEMO - Mouse Events DEMO uses e.which
and e.type

The question is really about scope, as the other guy put it.
In short, consider this "module":
Public Var1 As variant 'Var1 can be used in all
'modules, class modules and userforms of
'thisworkbook and will preserve any values
'assigned to it until either the workbook
'is closed or the project is reset.
Dim Var2 As Variant 'Var2 and Var3 can be used anywhere on the
Private Var3 As Variant ''current module and will preserve any values
''they're assigned until either the workbook
''is closed or the project is reset.
Sub MySub() 'Var4 can only be used within the procedure MySub
Dim Var4 as Variant ''and will only store values until the procedure
End Sub ''ends.
Sub MyOtherSub() 'You can even declare another Var4 within a
Dim Var4 as Variant ''different procedure without generating an
End Sub ''error (only possible confusion).
You can check out this MSDN reference for more on variable declaration and this other Stack Overflow Question for more on how variables go out of scope.
Two other quick things:
You don't really need jQuery for this. You could do it with plain javascript using the setTimeout method:
// redirect to google after 5 seconds
window.setTimeout(function() {
window.location.href = 'http://www.google.com';
}, 5000);
All tables should have a primary key (consisting of a single or multiple columns), duplicate rows doesn't make sense in a relational database. You can limit the number of delete rows using LIMIT
though:
DELETE FROM orders WHERE id_users = 1 AND id_product = 2 LIMIT 1
But that just solves your current issue, you should definitely work on the bigger issue by defining primary keys.

Starting from material components android 1.2.0-alpha01, you have slider
component
ex:
<com.google.android.material.slider.Slider
android:id="@+id/slider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:valueFrom="20f"
android:valueTo="70f"
android:stepSize="10" />
I had similar problem (in bash terminal command was working correctly but zsh showed command not found error)
just paste whatever you were earlier pasting in ~/.bashrc to:
~/.zshrc
You could try something like this:
...Binding="{Binding RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type Window}}, Path=DataContext.AllowItemCommand}" ...
In the XML file set the android:checkedButton

...../>
<RadioButton
android:id="@+id/button_2"
...../>
<RadioButton

If your server is expecting the POST request to be json, then you would need to add a header, and also serialize the data for your request...
Python 2.x
import json
import urllib2
data = {
'ids': [12, 3, 4, 5, 6]
}
req = urllib2.Request('http://example.com/api/posts/create')
req.add_header('Content-Type', 'application/json')
response = urllib2.urlopen(req, json.dumps(data))
Python 3.x
https://stackoverflow.com/a/26876308/496445
If you don't specify the header, it will be the default application/x-www-form-urlencoded
type.
The example provided by Mykhaylo Adamovych is very thorough and exposes most of the major features of JSch. I packaged this code (with attribution, of course) into an open-source library called Remote Session. I added JavaDoc and custom exceptions, and I also provided a facility to specify custom session parameters (RemoteConfig).
One feature that Mykhaylo's code doesn't demonstrate is how to provide an "identity" for remote system interactions. This is critical if you're going to execute commands that require super-user access (i.e. - sudo). Remote Session adds this capability in its SessionHolder.newSession() implementation:
RemoteConfig remoteConfig = RemoteConfig.getConfig();
Path keyPath = remoteConfig.getKeyPath();
if (keyPath == null) {
throw new RemoteCredentialsUnspecifiedException();
}
String keyPass = remoteConfig.getString(RemoteSettings.SSH_KEY_PASS.key());
if (keyPass != null) {
Path pubPath = keyPath.resolveSibling(keyPath.getFileName() + ".pub");
jsch.addIdentity(keyPath.toString(), pubPath.toString(), keyPass.getBytes());
} else {
jsch.addIdentity(keyPath.toString());
}
Note that this behavior is bypassed if the remote system URL includes credentials.
Another feature that Remote Session demonstrates is how to provide a known-hosts file:
if ( ! remoteConfig.getBoolean(RemoteSettings.IGNORE_KNOWN_HOSTS.key())) {
Path knownHosts = keyPath.resolveSibling("known_hosts");
if (knownHosts.toFile().exists()) {
jsch.setKnownHosts(knownHosts.toString());
}
}
Remote Session also adds a ChannelStream class that encapsulates input/output operation for the channel attached to this session. This provides the ability to accumulate the output from the remote session until a specified prompt is received:
private boolean appendAndCheckFor(String prompt, StringBuilder input, Logger logger) throws InterruptedException, IOException {
String recv = readChannel(false);
if ( ! ((recv == null) || recv.isEmpty())) {
input.append(recv);
if (logger != null) {
logger.debug(recv);
}
if (input.toString().contains(prompt)) {
return false;
}
}
return !channel.isClosed();
}
Nothing too complicated, but this can greatly simplify the implementation of interactive remote operations.
Only Objective-C is allowed by now... but since a few months ago you are allowed to write scripts that will be interpreted in your application.
So you may be able to write a LUA interpreter or a Python interpreter, then write some part of your application in this scripting language. If you want your application accepted on the App Store, these scripts have to be bundled with the application (your application cannot download it from the Internet for example)
Mine did not start because the Server did not accept the 'Dedicated MySQL Server' setting in the Configuration.
Regarding jQuery
, the following common methods will also remove other constructs such as data and event handlers:
In addition to the elements themselves, all bound events and jQuery data associated with the elements are removed.
To avoid memory leaks, jQuery removes other constructs such as data and event handlers from the child elements before removing the elements themselves.
Additionally, jQuery removes other constructs such as data and event handlers from child elements before replacing those elements with the new content.
The easiest solution working fine for me is this:
export CFLAGS=-ggdb
export CXXFLAGS=-ggdb
CMake will append them to all configurations' flags. Just make sure to clear CMake cache.
One option is to bind a handler to the input
event.
The advantage of this approach is that we don't prevent keyboard behaviors that the user expects (e.g. tab, page up/down, etc.).
Another advantage is that it also handles the case when the input value is changed by pasting text through the context menu.
This approach works best if you only care about keeping the input empty. If you want to maintain a specific value, you'll have to track that somewhere else (in a data attribute?) since it will not be available when the input
event is received.
const inputEl = document.querySelector('input');_x000D_
_x000D_
inputEl.addEventListener('input', (event) => {_x000D_
event.target.value = '';_x000D_
});
_x000D_
<input type="text" />
_x000D_
Tested in Safari 10, Firefox 49, Chrome 54, IE 11.
My original answer regarding :nth-of-type
is simply wrong. Thanks to Paul for pointing this out.
The word "type" there refers only to the "element type" (like div
). It turns out that the selectors div.bar:nth-of-type(2)
and div:nth-of-type(2).bar
mean the same thing. Both select elements that [a] are the second div
of their parent, and [b] have class bar
.
So the only pure CSS solution left that I'm aware of, if you want to select all elements of a certain selector except the first, is the general sibling selector:
.bar ~ .bar
http://www.w3schools.com/cssref/sel_gen_sibling.asp
My original (wrong) answer follows:
With the arrival of CSS3, there is another option. It may not have been available when the question was first asked:
.bar:nth-of-type(2)
http://www.w3schools.com/cssref/sel_nth-of-type.asp
This selects the second element that satisfies the .bar
selector.
If you want the second and last of a specific kind of element (or all of them except the first), the general sibling selector would also work fine:
.bar ~ .bar
http://www.w3schools.com/cssref/sel_gen_sibling.asp
It's shorter. But of course, we don't like to duplicate code, right? :-)

The route admin_edit_location
:
admin_edit_location:
path: /edit_location/{id}
defaults: { _controller: "AppBundle:Admin:editLocation" }
methods: GET
And the controller
public function editLocationAction($id){
// use $id
$em = $this->getDoctrine()->getManager();
$location = $em->getRepository('BackendBundle:locations')->findOneBy(array(
'id' => $id
));
}
You can change this in the page load
.
My intention is that when the page comes to the load
function, switch the links (the current link in the required one)
For Python versions prior to 2.6, use the string formatting operator %
:
filename = "ME%d.txt" % i
For 2.6 and later, use the str.format()
method:
filename = "ME{0}.txt".format(i)
Though the first example still works in 2.6, the second one is preferred.
If you have more than 10 files to name this way, you might want to add leading zeros so that the files are ordered correctly in directory listings:
filename = "ME%02d.txt" % i
filename = "ME{0:02d}.txt".format(i)
This will produce file names like ME00.txt
to ME99.txt
. For more digits, replace the 2
in the examples with a higher number (eg, ME{0:03d}.txt
).
I tried @david answer, and it didn't fix my issue. after a lot of hassle, I made a method and return the image with style string.
HTML Code
<div v-for="slide in loadSliderImages" :key="slide.id">
<div v-else :style="bannerBgImage(slide.banner)"></div>
</div>
Method
bannerBgImage(image){
return 'background-image: url("' + image + '")';
},
One more option, not exactly what you asked, but can be useful:
Go to Settings
-> Editor
-> File and code templates
-> Includes
tab (on the right). There is a template header for the new files, you can use the username here:
/**
* @author myname
*/
For system username use:
/**
* @author ${USER}
*/
OpenCV has region of interest functions which you may find useful. If you are using the cv::Mat
then you could use something like the following.
// You mention that you start with a CVMat* imagesource
CVMat * imagesource;
// Transform it into the C++ cv::Mat format
cv::Mat image(imagesource);
// Setup a rectangle to define your region of interest
cv::Rect myROI(10, 10, 100, 100);
// Crop the full image to that image contained by the rectangle myROI
// Note that this doesn't copy the data
cv::Mat croppedImage = image(myROI);
I found this code working:
from distutils.dir_util import copy_tree
# copy subdirectory example
fromDirectory = "/a/b/c"
toDirectory = "/x/y/z"
copy_tree(fromDirectory, toDirectory)

As @Alex McMillan mentioned, use state to dictate what should be rendered in the dom.
In the example below I have an input field and I want to add a second one when the user clicks the button, the onClick event handler calls handleAddSecondInput( ) which changes inputLinkClicked to true. I am using a ternary operator to check for the truthy state, which renders the second input field
class HealthConditions extends React.Component {
constructor(props) {
super(props);
this.state = {
inputLinkClicked: false
}
}
handleAddSecondInput() {
this.setState({
inputLinkClicked: true
})
}
render() {
return(
<main id="wrapper" className="" data-reset-cookie-tab>
<div id="content" role="main">
<div className="inner-block">
<H1Heading title="Tell us about any disabilities, illnesses or ongoing conditions"/>
<InputField label="Name of condition"
InputType="text"
InputId="id-condition"
InputName="condition"
/>
{
this.state.inputLinkClicked?
<InputField label=""
InputType="text"
InputId="id-condition2"
InputName="condition2"
/>
:
<div></div>
}
<button

this.state.illnessOrDisability === 'true' ?

}
/>
<BackLink backLink="/add-your-details" />
</div>
</div>
</main>
);
}
}
I would like to read the versionCode from an external file
I am sure that there are any number of possible solutions; here is one:
android {
compileSdkVersion 18
buildToolsVersion "18.1.0"
def versionPropsFile = file('version.properties')
if (versionPropsFile.canRead()) {
def Properties versionProps = new Properties()
versionProps.load(new FileInputStream(versionPropsFile))
def code = versionProps['VERSION_CODE'].toInteger() + 1
versionProps['VERSION_CODE']=code.toString()
versionProps.store(versionPropsFile.newWriter(), null)
defaultConfig {
versionCode code
versionName "1.1"
minSdkVersion 14
targetSdkVersion 18
}
}
else {
throw new GradleException("Could not read version.properties!")
}
// rest of android block goes here
}
This code expects an existing version.properties
file, which you would create by hand before the first build to have VERSION_CODE=8
.
This code simply bumps the version code on each build -- you would need to extend the technique to handle your per-flavor version code.
You can see the Versioning sample project that demonstrates this code.
Try the jquery each
function to walk through your json object:
$.each(data,function(i,j){
content ='<span>'+j[i].Id+'<br />'+j[i].Name+'<br /></span>';
$('#ProductList').append(content);
});
Maybe a bit late, but the answer to all of this mess is that call() is used in JS for inheritance. If we compare this to Python or PHP, for example, call is used respectively as super().init() or parent::_construct().
This is an example of its usage that clarifies all:
function Teacher(first, last, age, gender, interests, subject) {
Person.call(this, first, last, age, gender, interests);
this.subject = subject;
}

Tested on Ubuntu 18.10.
Schema
Ortho: camera is a plane, visible volume a rectangle:
Frustrum: camera is a point,visible volume a slice of a pyramid:
Parameters
We are always looking from +z to -z with +y upwards:
glOrtho(left, right, bottom, top, near, far)
left
: minimum x
we seeright
: maximum x
we seebottom
: minimum y
we seetop
: maximum y
we see-near
: minimum z
we see. Yes, this is -1
times near
. So a negative input means positive z
.-far
: maximum z
we see. Also negative.Schema:
How it works under the hood
In the end, OpenGL always "uses":
glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);
If we use neither glOrtho
nor glFrustrum
, that is what we get.
glOrtho
and glFrustrum
are just linear transformations (AKA matrix multiplication) such that:
glOrtho
: takes a given 3D rectangle into the default cubeglFrustrum
: takes a given pyramid section into the default cubeThis transformation is then applied to all vertexes. This is what I mean in 2D:
The final step after transformation is simple:
x
, y
and z
are in [-1, +1]
z
component and take only x
and y
, which now can be put into a 2D screenWith glOrtho
, z
is ignored, so you might as well always use 0
.
One reason you might want to use z != 0
is to make sprites hide the background with the depth buffer.
Deprecation
glOrtho
is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.
So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.
Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.
Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.
Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations. See also: https://stackoverflow.com/a/36211337/895245
With an explicit GLfloat transform[]

Output:
The matrix for glOrtho
is really simple, composed only of scaling and translation:
scalex, 0, 0, translatex,
0, scaley, 0, translatey,
0, 0, scalez, translatez,
0, 0, 0, 1
as mentioned in the OpenGL 2 docs.
The glFrustum
matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho
, more info at: https://gamedev.stackexchange.com/a/118848/25171
The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho
and frustum
operations.
Cconvert NSTimeInterval
milisecondedDate
value to nsstring
and after that convert into int
.
VLookup
You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".
External Reference
To reference a cell of the same Workbook use the following pattern:
<Sheetname>!<Cell>
Example:
Table1!A1
To reference a cell of a different Workbook use this pattern:
[<Workbook_name>]<Sheetname>!<Cell>
Example:
[MyWorkbook]Table1!A1
This code is for:
Here is the code, which is based on @milz 's answer:
DB::listen(function($sql) {
$LOG_TABLE_NAME = 'log';
foreach ($sql->bindings as $i => $binding) {
if ($binding instanceof \DateTime) {
$sql->bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
} else {
if (is_string($binding)) {
$sql->bindings[$i] = "'$binding'";
}
}
}
// Insert bindings into query
$query = str_replace(array('%', '?'), array('%%', '%s'), $sql->sql);
$query = vsprintf($query, $sql->bindings);
if(stripos($query, 'insert into `'.$LOG_TABLE_NAME.'`')===false){
$toLog = new LogModel();
$toLog->uId = 100;
$toLog->sql = $query;
$toLog->save();
}
});
The core is the if(stripos...
line, which prevents the recursion of inserting the insert into log
sql statement into database.

You can do this:
#include <cmath>
#ifndef M_PI
#define M_PI (3.14159265358979323846)
#endif
If M_PI
is already defined in cmath
, this won't do anything else than include cmath
. If M_PI
isn't defined (which is the case for example in Visual Studio), it will define it. In both cases, you can use M_PI
to get the value of pi.
This value of pi comes from Qt Creator's qmath.h.
take a look at jQuery plugin "Swapable"
http://code.google.com/p/jquery-swapable/
it's built on "Sortable" and looks like sortable (drag-n-drop, placeholder, etc.) but only swap two elements: dragged and dropped. All other elements are not affected and stay on their current position.
public class Statistics {
double[] data;
int size;
public Statistics(double[] data) {
this.data = data;
size = data.length;
}
double getMean() {
double sum = 0.0;
for(double a : data)
sum += a;
return sum/size;
}
double getVariance() {
double mean = getMean();
double temp = 0;
for(double a :data)
temp += (a-mean)*(a-mean);
return temp/(size-1);
}
double getStdDev() {
return Math.sqrt(getVariance());
}
public double median() {
Arrays.sort(data);
if (data.length % 2 == 0)
return (data[(data.length / 2) - 1] + data[data.length / 2]) / 2.0;
return data[data.length / 2];
}
}
A more groovyesque approach would be to use inject in combination with metaClass:
I would to love to say:
String myInput="This string is FORBIDDEN"
myInput.containsAny(["FORBIDDEN","NOT_ALLOWED"]) //=>true
And the method would be:
myInput.metaClass.containsAny={List<String> notAllowedTerms->
notAllowedTerms?.inject(false,{found,term->found || delegate.contains(term)})
}
If you need containsAny to be present for any future String variable then add the method to the class instead of the object:
String.metaClass.containsAny={notAllowedTerms->
notAllowedTerms?.inject(false,{found,term->found || delegate.contains(term)})
}
My problem was took IBOutlet
but didn't connect with interface builder and using in swift file.
Well, my case when you don't want to care about files list. Just show them all.
When you already ran git add
with your files list:
$ git diff --cached $(git diff --cached --name-only)
In more recent versions of git
, you can use --staged
also, which is a synonym of --cached
.
The same can be used for haven't added files but without --cached
option.
$ git diff $(git diff --name-only)
Git command alias for "cached" option:
$ git config --global alias.diff-cached '!git diff --cached $(git diff --cached --name-only)'

To describe model I use following snippet
Model.columns.collect { |c| "#{c.name} (#{c.type})" }
Again this is if you are looking pretty print to describe you ActiveRecord
without you going trough migrations or hopping that developer before you was nice enough to comment in attributes.
Java doesn't pass objects, it passes references (pointers) to objects. So yes, l2 and l1 are two pointers to the same object.
You have to make an explicit copy if you need two different list with the same contents.
I've experienced a problem with length of None, which leads to Internal Server Error: TypeError: object of type 'NoneType' has no len()
My workaround is just displaying 0 if object is None and calculate length of other types, like list in my case:
{{'0' if linked_contacts == None else linked_contacts|length}}
The Immediate Window can also be used to execute commands. Just type a >
followed by the command.
For example >shell cmd
will start a command shell (this can be useful to check what environment variables were passed to Visual Studio, for example). >cls
will clear the screen.
Here is a list of commands that are so commonly used that they have their own aliases: https://msdn.microsoft.com/en-us/library/c3a0kd3x.aspx
Enum is just a little bit special class. Enums can store additional fields, implement methods etc. For example
public enum Modes {
mode1('a'),
mode2('b'),
mode3('c'),
;
char c;
private Modes(char c) {
this.c = c;
}
public char character() {
return c;
}
}
Now you can say:
System.out.println(Modes.mode1.character())
and see output:
a
If you use Tomcat server I suggest you to put JSTL .jar file to the Tomcat lib folder. By doing this you will have an access to JSTL in all your web projects automatically (with taglib declaration in .jsp files of course).
If elements are always nearly sorted as in your example then builtin .sort()
(timsort) should be fast:
>>> a = [1,1,2]
>>> b = [1,2,2]
>>> a.sort()
>>> b.sort()
>>> a == b
False
If you don't want to sort inplace you could use sorted()
.
In practice it might always be faster then collections.Counter()
(despite asymptotically O(n)
time being better then O(n*log(n))
for .sort()
). Measure it; If it is important.
I had a similar problem and tested different ways to solve it.
Eventually I understood that my index.htm file had been saved with "Unicode" encoding (for using Farsi characters in my page) while my .css file had been save with "ANSI" format.
I changed the encoding of my .css file to "Unicode" with Notepad and the problem got solved.
A possible solution is:
java.awt.EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
myFrame.toFront();
myFrame.repaint();
}
});
Alternatively, you can use XPath query via XPathSelectElements
method:
var document = XDocument.Parse(yourXmlAsString);
var words = document.XPathSelectElements("//word[./category[text() = 'verb']]");
What database are you on? With MS SQL Server, it's a database-wide setting, or you can over-ride it per-query with the COLLATE keyword.
Its a bit counter-intuitive. The toolchain is called gcc-arm-linux-gnueabi. To invoke the tools execute the following: arm-linux-gnueabi-xxx
where xxx is gcc or ar or ld, etc
As recommended qTip and other projects are quite old I recommend using qTip2 as it is most up-to-date.
If you want to avoid drawing it yourself, you could use the undocumented class: UINavigationButton with style 1. This could, of course, stop your application from being approved... /John
I've found nosklo's answer very extensive and useful! For those, like myself, who might find accessing the raw request data directly also useful, I would like to add the way to do that:
import os, sys
# the query string, which contains the raw GET data
# (For example, for http://example.com/myscript.py?a=b&c=d&e
# this is "a=b&c=d&e")
os.getenv("QUERY_STRING")
# the raw POST data

The best way to solve your problem is to set the UseSystemPasswordChar
property to true. Then, the Caps-lock message is shown when the user enters the field and the Caps-Lock is on (at least for Vista and Windows 7).
Another alternative is to set the PasswordChar
property to a character value (* for example). This also triggers the automatic Caps-Lock handling.
As the cast
operation is available for Spark Column
's (and as I personally do not favour udf
's as proposed by @Svend
at this point), how about:
df.select( df("year").cast(IntegerType).as("year"), ... )
to cast to the requested type? As a neat side effect, values not castable / "convertable" in that sense, will become null
.
In case you need this as a helper method, use:
object DFHelper{
def castColumnTo( df: DataFrame, cn: String, tpe: DataType ) : DataFrame = {
df.withColumn( cn, df(cn).cast(tpe) )
}
}
which is used like:
import DFHelper._
val df2 = castColumnTo( df, "year", IntegerType )
Sleep() causes the currently executing thread to sleep (temporarily cease execution).
Yield() causes the currently executing thread object to temporarily pause and allow other threads to execute.
