Let's go over the basics: "Accessor" and "Mutator" are just fancy names fot a getter and a setter. A getter, "Accessor", returns a class's variable or its value. A setter, "Mutator", sets a class variable pointer or its value.
So first you need to set up a class with some variables to get/set:
public class IDCard
{
private String mName;
private String mFileName;
private int mID;
}
But oh no! If you instantiate this class the default values for these variables will be meaningless. B.T.W. "instantiate" is a fancy word for doing:
IDCard test = new IDCard();
So - let's set up a default constructor, this is the method being called when you "instantiate" a class.
public IDCard()
{
mName = "";
mFileName = "";
mID = -1;
}
But what if we do know the values we wanna give our variables? So let's make another constructor, one that takes parameters:
public IDCard(String name, int ID, String filename)
{
mName = name;
mID = ID;
mFileName = filename;
}
Wow - this is nice. But stupid. Because we have no way of accessing (=reading) the values of our variables. So let's add a getter, and while we're at it, add a setter as well:
public String getName()
{
return mName;
}
public void setName( String name )
{
mName = name;
}
Nice. Now we can access mName. Add the rest of the accessors and mutators and you're now a certified Java newbie.
Good luck.
For Windows (7), the same folder is located at,
%APPDATA%\Subversion\auth
Type in the above in the Run(Win key + R) dialog box and hit Enter,
To check the existing username open the below file as a text file,
%APPDATA%\Subversion\auth\svn.simple\xxxxxxxxxx
If a DLL is written in one of the .NET languages and if you only want to view what functions, there is a reference to this DLL in the project.
Then doubleclick the DLL in the references folder and then you will see what functions it has in the OBJECT EXPLORER window
If you would like to view the source code of that DLL file you can use a decompiler application such as .NET reflector. hope this helps you.
if you just want to see the folder size and not the sub-folders, you can use:
du -hs /path/to/directory
Update:
You should know that du shows the used disk space; and not the file size.
You can use --apparent-size if u want to see sum of actual file sizes.
--apparent-size
print apparent sizes, rather than disk usage; although the apparent size is usually smaller, it may be larger due to holes in ('sparse')
files, internal fragmentation, indirect blocks, and the like
And of course theres no need for -h (Human readable) option inside a script.
Instead You can use -b for easier comparison inside script.
But You should Note that -b applies --apparent-size by itself. And it might not be what you need.
-b, --bytes
equivalent to '--apparent-size --block-size=1'
so I think, you should use --block-size or -B
#!/bin/bash
SIZE=$(du -B 1 /path/to/directory | cut -f 1 -d " ")
# 2GB = 2147483648 bytes
# 10GB = 10737418240 bytes
if [[ $SIZE -gt 2147483648 && $SIZE -lt 10737418240 ]]; then
echo 'Condition returned True'
fi
Use a timer. There are 3 basic kinds, each suited for different purposes.
Use only in a Windows Form application. This timer is processed as part of the message loop, so the the timer can be frozen under high load.
When you need synchronicity, use this one. This means that the tick event will be run on the thread that started the timer, allowing you to perform GUI operations without much hassle.
This is the most high-powered timer, which fires ticks on a background thread. This lets you perform operations in the background without freezing the GUI or the main thread.
For most cases, I recommend System.Timers.Timer.
A nested dict is a dictionary within a dictionary. A very simple thing.
>>> d = {}
>>> d['dict1'] = {}
>>> d['dict1']['innerkey'] = 'value'
>>> d
{'dict1': {'innerkey': 'value'}}
You can also use a defaultdict from the collections package to facilitate creating nested dictionaries.
>>> import collections
>>> d = collections.defaultdict(dict)
>>> d['dict1']['innerkey'] = 'value'
>>> d # currently a defaultdict type
defaultdict(<type 'dict'>, {'dict1': {'innerkey': 'value'}})
>>> dict(d) # but is exactly like a normal dictionary.
{'dict1': {'innerkey': 'value'}}
You can populate that however you want.
I would recommend in your code something like the following:
d = {} # can use defaultdict(dict) instead
for row in file_map:
# derive row key from something
# when using defaultdict, we can skip the next step creating a dictionary on row_key
d[row_key] = {}
for idx, col in enumerate(row):
d[row_key][idx] = col
According to your comment:
may be above code is confusing the question. My problem in nutshell: I have 2 files a.csv b.csv, a.csv has 4 columns i j k l, b.csv also has these columns. i is kind of key columns for these csvs'. j k l column is empty in a.csv but populated in b.csv. I want to map values of j k l columns using 'i` as key column from b.csv to a.csv file
My suggestion would be something like this (without using defaultdict):
a_file = "path/to/a.csv"
b_file = "path/to/b.csv"
# read from file a.csv
with open(a_file) as f:
# skip headers
f.next()
# get first colum as keys
keys = (line.split(',')[0] for line in f)
# create empty dictionary:
d = {}
# read from file b.csv
with open(b_file) as f:
# gather headers except first key header
headers = f.next().split(',')[1:]
# iterate lines
for line in f:
# gather the colums
cols = line.strip().split(',')
# check to make sure this key should be mapped.
if cols[0] not in keys:
continue
# add key to dict
d[cols[0]] = dict(
# inner keys are the header names, values are columns
(headers[idx], v) for idx, v in enumerate(cols[1:]))
Please note though, that for parsing csv files there is a csv module.
The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:
<button type="button"> to override default submission behaviorevent.preventDefault() in the onSubmit event to prevent form submissionInsert extra type attribute to your button markup:
<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>
Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:
$(document).ready(function () {
// Listen to click event on the submit button
$('#button').click(function (e) {
e.preventDefault();
var name = $("#name").val();
var email = $("#email").val();
$.post("process.php", {
name: name,
email: email
}).complete(function() {
console.log("Success");
});
});
});
In this improvement, we listen to the submit event emitted from the <form> element:
$(document).ready(function () {
// Listen to submit event on the <form> itself!
$('#main').submit(function (e) {
e.preventDefault();
var name = $("#name").val();
var email = $("#email").val();
$.post("process.php", {
name: name,
email: email
}).complete(function() {
console.log("Success");
});
});
});
.serialize() to serialize your form, but remember to add name attributes to your input:The name attribute is required for .serialize() to work, as per jQuery's documentation:
For a form element's value to be included in the serialized string, the element must have a name attribute.
<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">
And then in your JS:
$(document).ready(function () {
// Listen to submit event on the <form> itself!
$('#main').submit(function (e) {
// Prevent form submission which refreshes page
e.preventDefault();
// Serialize data
var formData = $(this).serialize();
// Make AJAX request
$.post("process.php", formData).complete(function() {
console.log("Success");
});
});
});
I had a similar issue after upgrading to a new swift version recently. Moving files around caused my xcode project to reference items that were no longer in the project directory giving me the Error Code Build Input File Not Found.
In my situation I somehow had multiple files/images that were being referenced as described below:
In the image above.
It was in here that I somehow had multiple files and images that were being referenced from other folders and the build would fail as they could no longer find them. And I could not find them either! or how Xcode was still referencing them
I hope this helps someone else !
If you use Flutter, then you can access it via people.googleapis.com endpoint, code uses google_sign_in library
import 'package:google_sign_in/google_sign_in.dart';
Future<String> getPhotoUrl(GoogleSignInAccount account, String userId) async {
// final authentication = await account.authentication;
final url = 'https://people.googleapis.com/v1/people/${userId}?personFields=photos';
final response = await http.get(
url,
headers: await account.authHeaders
);
final data = json.decode(response.body);
return data['photos'].first['url'];
}
You will get something like
{
resourceName: people/998812322529259873423,
etag: %EgQBAzcabcQBAgUH,
photos: [{metadata: {primary: true, source: {type: PROFILE, id: 107721622529987673423}},
url: https://lh3.googleusercontent.com/a-/abcdefmB2p1VWxLsNT9WSV0yqwuwo6o2Ba21sh_ra7CnrZ=s100}]
}
where url is an accessible image url.
Use the Key keyword in your select will work, like below.
product.Select(m => new {Key m.CategoryId, Key m.CategoryName}).Distinct();
I realize this is bringing up an old thread but figured it might help some people. I generally code in VB.NET when working with .NET so Key may translate differently into C#.
THIS works

Try this Toggle Buttons
test_activity.xml

private ToggleButton togglebutton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
togglebutton = (ToggleButton) findViewById(R.id.togglebutton);
}
public void toggleclick(View v){
if(togglebutton.isChecked())
Toast.makeText(TestActivity.this, "ON", Toast.LENGTH_SHORT).show();
else
Toast.makeText(TestActivity.this, "OFF", Toast.LENGTH_SHORT).show();
}
}
Make a third column that has values like:
=IF(A1="Airline",B1)
=IF(A2="Airline",B2) etc
Then just perform a median on the new column.
I'm surprised noone's voted up Shao's answer that, as I understand it, it is impossible to do what's asked in standard C99, since converting a pointer to an integral type formally is undefined behavior. (Apart from the standard allowing conversion of uintptr_t <-> void*, but the standard does not seem to allow doing any manipulations of the uintptr_t value and then converting it back.)
You can use the mysqli multi_query function as below:
$sql = file_get_contents('mysqldump.sql');
$mysqli = new mysqli("localhost", "root", "pass", "testdb");
/* execute multi query */
$mysqli->multi_query($sql);
The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.
<h:outputLink value="destination.xhtml">link text</h:outputLink>
The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.
<h:form>
<h:commandLink value="link text" action="destination" />
</h:form>
The ?faces-redirect=true parameter on the <h:commandLink>, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href of the <a> element to be a fullworthy URL. It still remains #.
<h:form>
<h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>
Since JSF 2.0, there's also the <h:link> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a> element as well with the proper URL in href.
<h:link value="link text" outcome="destination" />
So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink> or <h:link>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.
When necessary, you can do the preprocessing job in the constructor or @PostConstruct of a @RequestScoped or @ViewScoped @ManagedBean which is attached to the destination page in question. You can make use of @ManagedProperty or <f:viewParam> to set GET parameters as bean properties.
Trick to update props if they are array :
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View,
Button
} from 'react-native';
class Counter extends Component {
constructor(props) {
super(props);
this.state = {
count: this.props.count
}
}
increment(){
console.log("this.props.count");
console.log(this.props.count);
let count = this.state.count
count.push("new element");
this.setState({ count: count})
}
render() {
return (
<View style={styles.container}>
<Text>{ this.state.count.length }</Text>
<Button
onPress={this.increment.bind(this)}
title={ "Increase" }
/>
</View>
);
}
}
Counter.defaultProps = {
count: []
}
export default Counter
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
See this link. It shows you how to dynamically create variables in PowerShell.
Here is the basic idea:
Use New-Variable and Get-Variable,
for ($i=1; $i -le 5; $i++)
{
New-Variable -Name "var$i" -Value $i
Get-Variable -Name "var$i" -ValueOnly
}
(It is taken from the link provided, and I don't take credit for the code.)
per various post... you cannot trigger a download via XHR. I needed to implement condition for the download, so, My solution was:
//make the call to the api with the ID to validate
someResource.get( { id: someId }, function(data) {
//confirm that the ID is validated
if (data.isIdConfirmed) {
//get the token from the validation and issue another call
//to trigger the download
window.open('someapi/print/:someId?token='+ data.token);
}
});
I wish that somehow, or someday the download can be triggered using XHR to avoid the second call. // _e
There's no shortcut for doing this in Java like the example you gave in Python.
You'd have to do this:
for (;i > 0; i--) {
somenum = somenum + "0";
}
AS Scott mentioned here http://weblogs.asp.net/scottgu/archive/2010/09/30/asp-net-security-fix-now-on-windows-update.aspx After windows installed security update for .net framework, you will meet this problem. just modify the configuration section in your web.config file and switch to a different cookie name.
I know this is old, but I had trouble with some solutions and pieced this together. I have tested this on Windows (Chrome, Firefox and MSIE) and OS X (Chrome and Safari) and believe this is the simplest solution. It works with these three style of attaching a label.
<label><input type="checkbox" class="c123" id="cb1" name="item1">item1</label>
<input type="checkbox" class="c123" id="cb2" name="item2">item2</input>
<input type="checkbox" class="c123" id="cb3" name="item3"><label for="cb3">item3</label>
Using jQuery:
$(".c123").click(function() {
$cb = $(this);
$lb = $(this).parent();
alert( $cb.attr('id') + ' = ' + $lb.text() );
});

Change that import to
from matplotlib.pyplot import *
Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:
import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
If you control the code of the tasks then you can work around the problem by letting a task trigger a trivial retry the first time it executes, then checking inspect().reserved(). The retry registers the task with the result backend, and celery can see that. The task must accept self or context as first parameter so we can access the retry count.
@task(bind=True)
def mytask(self):
if self.request.retries == 0:
raise self.retry(exc=MyTrivialError(), countdown=1)
...
This solution is broker agnostic, ie. you don't have to worry about whether you are using RabbitMQ or Redis to store the tasks.
EDIT: after testing I've found this to be only a partial solution. The size of reserved is limited to the prefetch setting for the worker.
The ID you are trying is an serverside.
That is going to render in the browser differently.
try to get the ID by watching the html in the Browser.
var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;
this may works.
Or do that ClientID method. That also works but ultimately the browser will get the same thing what i had written.
Webkit supports gradients in borders, and now accepts the gradient in the Mozilla format.
Firefox claims to support gradients in two ways:
IE9 has no support.
You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg
public class MyResult {
int returnCode;
String errorMessage;
// etc
}
public MyResult someMethod() {
// impl here
}
Using Focus method
Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
yourControl.Focus()
End Sub
The canonical way to get an interactive shell with docker-compose is to use:
docker-compose run --rm myapp
You can set stdin_open: true, tty: true, however that won't actually give you a proper shell with up, because logs are being streamed from all the containers.
You can also use
docker exec -ti <container name> /bin/bash
to get a shell on a running container.
Other way to get the minor version is:
SELECT extversion
FROM pg_catalog.pg_extension
WHERE extname='postgis'
You have a few issues with your code:
<select name="dbType" id=dbType"> should be <select name="dbType" id="dbType">
$('this') should be $(this): there is no need for the quotes inside the paranthesis.
use .val() instead of .value() when you want to retrieve the value of an option
when u initialize "selection" do it with a var in front of it, unless you already have done it at the beggining of the function
try this:
$('#dbType').on('change',function(){
if( $(this).val()==="other"){
$("#otherType").show()
}
else{
$("#otherType").hide()
}
});
UPDATE for use with switch:
$('#dbType').on('change',function(){
var selection = $(this).val();
switch(selection){
case "other":
$("#otherType").show()
break;
default:
$("#otherType").hide()
}
});
UPDATE with links for jQuery and jQuery-UI:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/jquery-ui.min.js"></script>??
You can also turn on WCF logging for more information about the original error. This helped me solve this problem.

It's baffling that they included a toLocaleString but not a parse method. At least toLocaleString without arguments is well supported in IE6+.
For a i18n solution, I came up with this:
First detect the user's locale decimal separator:
var decimalSeparator = 1.1;
decimalSeparator = decimalSeparator.toLocaleString().substring(1, 2);
Then normalize the number if there's more than one decimal separator in the String:
var pattern = "([" + decimalSeparator + "])(?=.*\\1)";separator
var formatted = valor.replace(new RegExp(pattern, "g"), "");
Finally, remove anything that is not a number or a decimal separator:
formatted = formatted.replace(new RegExp("[^0-9" + decimalSeparator + "]", "g"), '');
return Number(formatted.replace(decimalSeparator, "."));
Note that both the setLocationRelativeTo(null) and Tookit.getDefaultToolkit().getScreenSize() techniques work only for the primary monitor. If you are in a multi-monitor environment, you may need to get information about the specific monitor the window is on before doing this kind of calculation.
Sometimes important, sometimes not...
See GraphicsEnvironment javadocs for more info on how to get this.

Trying to open multiple panels of a collapse control that is setup as an accordion i.e. with the data-parent attribute set, can prove quite problematic and buggy (see this question on multiple panels open after programmatically opening a panel)
Instead, the best approach would be to:
To allow each panel to toggle individually, on the data-toggle="collapse" element, set the data-target attribute to the .collapse panel ID selector (instead of setting the data-parent attribute to the parent control. You can read more about this in the question Modify Twitter Bootstrap collapse plugin to keep accordions open.
Roughly, each panel should look like this:
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title"
data-toggle="collapse"
data-target="#collapseOne">
Collapsible Group Item #1
</h4>
</div>
<div id="collapseOne"
class="panel-collapse collapse">
<div class="panel-body"></div>
</div>
</div>
To manually enforce the accordion behavior, you can create a handler for the collapse show event which occurs just before any panels are displayed. Use this to ensure any other open panels are closed before the selected one is shown (see this answer to multiple panels open). You'll also only want the code to execute when the panels are active. To do all that, add the following code:
$('#accordion').on('show.bs.collapse', function () {
if (active) $('#accordion .in').collapse('hide');
});
Then use show and hide to toggle the visibility of each of the panels and data-toggle to enable and disable the controls.
$('#collapse-init').click(function () {
if (active) {
active = false;
$('.panel-collapse').collapse('show');
$('.panel-title').attr('data-toggle', '');
$(this).text('Enable accordion behavior');
} else {
active = true;
$('.panel-collapse').collapse('hide');
$('.panel-title').attr('data-toggle', 'collapse');
$(this).text('Disable accordion behavior');
}
});
This would work too:
document.getElementsByTagName('p')[0].id
(If element where the 1st paragraph in your document)
I'd recommend using JQuery's keyup and keydown methods on the document, as it normalizes the event codes, to make one solution crossbrowser.
For the right click, you can use oncontextmenu, however beware it can be buggy in IE8. See a chart of compatibility here:
http://www.quirksmode.org/dom/events/contextmenu.html
<p onclick="selectMe(1)" oncontextmenu="selectMe(2)">Click me</p>
$(document).keydown(function(event){
if(event.which=="17")
cntrlIsPressed = true;
});
$(document).keyup(function(){
cntrlIsPressed = false;
});
var cntrlIsPressed = false;
function selectMe(mouseButton)
{
if(cntrlIsPressed)
{
switch(mouseButton)
{
case 1:
alert("Cntrl + left click");
break;
case 2:
alert("Cntrl + right click");
break;
default:
break;
}
}
}
I know this is kind of late but this plugin should work. http://remysharp.com/2009/01/26/element-in-view-event-plugin/
$('p.inview').bind('inview', function (event, visible) {
if (visible) {
$(this).text('You can see me!');
} else {
$(this).text('Hidden again');
}
Run this from the branch where you want the file to end up:
git checkout otherbranch myfile.txt
General formulas:
git checkout <commit_hash> <relative_path_to_file_or_dir>
git checkout <remote_name>/<branch_name> <file_or_dir>
Some notes (from comments):
myfile.txt and mydiran alternative:
git show commit_id:path/to/file > path/to/file
Clearing the value of 0th index of input worked for me. Please try the below code, hope this will work (AngularJs).
scope.onClick = function() {
input[0].value = "";
input.click();
};
Just to clarify what yalestar said, this will give you the relative path:
Workbooks.Open FileName:= ThisWorkbook.Path & "\TRICATEndurance Summary.html"
Public - If you can see the class, then you can see the method
Private - If you are part of the class, then you can see the method, otherwise not.
Protected - Same as Private, plus all descendants can also see the method.
Static (class) - Remember the distinction between "Class" and "Object" ? Forget all that. They are the same with "static"... the class is the one-and-only instance of itself.
Static (method) - Whenever you use this method, it will have a frame of reference independent of the actual instance of the class it is part of.
Using homebrew install nvm:
brew update
brew install nvm
source $(brew --prefix nvm)/nvm.sh
Add the last command to the .profile, .bashrc or .zshrc file to not run it again on every terminal start. So for example to add it to the .profile run:
echo "source $(brew --prefix nvm)/nvm.sh" >> ~/.profile
If you have trouble with installing nvm using brew you can install it manually (see here)
Using nvm install node or iojs (you can install any version you want):
nvm install 0.10
# or
nvm install iojs-1.2.0
npm is shipping with node (or iojs), so it will be available after installing node (or iojs). You may want to upgrade it to the latest version:
$ npm install -g npm@latest
UPD Previous version was npm update -g npm
Using npm install ionic:
npm install -g ionic
What about ngCordova: you can install it using npm or bower. I don't know what variant is more fit for you, it depends on the package manager you want to use for the client side. So I'll describe them both:
Using npm: Go to your project folder and install ng-cordova in it:
npm install --save ng-cordova
Using bower: Install bower:
npm install -g bower
And then go to your project folder and install ngCordova in it:
bower install --save ngCordova

Here is the raw way to do it
$startTimeStamp = strtotime("2011/07/01");
$endTimeStamp = strtotime("2011/07/17");
$timeDiff = abs($endTimeStamp - $startTimeStamp);
$numberDays = $timeDiff/86400; // 86400 seconds in one day
// and you might want to convert to integer
$numberDays = intval($numberDays);
you can use CURRENT_TIMESTAMP, mysql function

Actually the purpose of np.meshgrid is already mentioned in the documentation:
Return coordinate matrices from coordinate vectors.
Make N-D coordinate arrays for vectorized evaluations of N-D scalar/vector fields over N-D grids, given one-dimensional coordinate arrays x1, x2,..., xn.
So it's primary purpose is to create a coordinates matrices.
You probably just asked yourself:
The reason you need coordinate matrices with Python/NumPy is that there is no direct relation from coordinates to values, except when your coordinates start with zero and are purely positive integers. Then you can just use the indices of an array as the index. However when that's not the case you somehow need to store coordinates alongside your data. That's where grids come in.
Suppose your data is:
1 2 1
2 5 2
1 2 1
However, each value represents a 3 x 2 kilometer area (horizontal x vertical). Suppose your origin is the upper left corner and you want arrays that represent the distance you could use:
import numpy as np
h, v = np.meshgrid(np.arange(3)*3, np.arange(3)*2)
where v is:
array([[0, 0, 0],
[2, 2, 2],
[4, 4, 4]])
and h:
array([[0, 3, 6],
[0, 3, 6],
[0, 3, 6]])
So if you have two indices, let's say x and y (that's why the return value of meshgrid is usually xx or xs instead of x in this case I chose h for horizontally!) then you can get the x coordinate of the point, the y coordinate of the point and the value at that point by using:
h[x, y] # horizontal coordinate
v[x, y] # vertical coordinate
data[x, y] # value
That makes it much easier to keep track of coordinates and (even more importantly) you can pass them to functions that need to know the coordinates.
However, np.meshgrid itself isn't often used directly, mostly one just uses one of similar objects np.mgrid or np.ogrid.
Here np.mgrid represents the sparse=False and np.ogrid the sparse=True case (I refer to the sparse argument of np.meshgrid). Note that there is a significant difference between
np.meshgrid and np.ogrid and np.mgrid: The first two returned values (if there are two or more) are reversed. Often this doesn't matter but you should give meaningful variable names depending on the context.
For example, in case of a 2D grid and matplotlib.pyplot.imshow it makes sense to name the first returned item of np.meshgrid x and the second one y while it's
the other way around for np.mgrid and np.ogrid.
np.ogrid and sparse grids>>> import numpy as np
>>> yy, xx = np.ogrid[-5:6, -5:6]
>>> xx
array([[-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5]])
>>> yy
array([[-5],
[-4],
[-3],
[-2],
[-1],
[ 0],
[ 1],
[ 2],
[ 3],
[ 4],
[ 5]])
As already said the output is reversed when compared to np.meshgrid, that's why I unpacked it as yy, xx instead of xx, yy:
>>> xx, yy = np.meshgrid(np.arange(-5, 6), np.arange(-5, 6), sparse=True)
>>> xx
array([[-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5]])
>>> yy
array([[-5],
[-4],
[-3],
[-2],
[-1],
[ 0],
[ 1],
[ 2],
[ 3],
[ 4],
[ 5]])
This already looks like coordinates, specifically the x and y lines for 2D plots.
Visualized:
yy, xx = np.ogrid[-5:6, -5:6]

The same applies here: The output is reversed compared to np.meshgrid:

Unlike ogrid these arrays contain all xx and yy coordinates in the -5 <= xx <= 5; -5 <= yy <= 5 grid.
yy, xx = np.mgrid[-5:6, -5:6]

It's not only limited to 2D, these functions work for arbitrary dimensions (well, there is a maximum number of arguments given to function in Python and a maximum number of dimensions that NumPy allows):
>>> x1, x2, x3, x4 = np.ogrid[:3, 1:4, 2:5, 3:6]
>>> for i, x in enumerate([x1, x2, x3, x4]):
... print('x{}'.format(i+1))
... print(repr(x))
x1
array([[[[0]]],
[[[1]]],
[[[2]]]])
x2
array([[[[1]],
[[2]],
[[3]]]])
x3
array([[[[2],
[3],
[4]]]])
x4
array([[[[3, 4, 5]]]])
>>> # equivalent meshgrid output, note how the first two arguments are reversed and the unpacking
>>> x2, x1, x3, x4 = np.meshgrid(np.arange(1,4), np.arange(3), np.arange(2, 5), np.arange(3, 6), sparse=True)
>>> for i, x in enumerate([x1, x2, x3, x4]):
... print('x{}'.format(i+1))
... print(repr(x))
# Identical output so it's omitted here.
Even if these also work for 1D there are two (much more common) 1D grid creation functions:
Besides the start and stop argument it also supports the step argument (even complex steps that represent the number of steps):
>>> x1, x2 = np.mgrid[1:10:2, 1:10:4j]
>>> x1 # The dimension with the explicit step width of 2
array([[1., 1., 1., 1.],
[3., 3., 3., 3.],
[5., 5., 5., 5.],
[7., 7., 7., 7.],
[9., 9., 9., 9.]])
>>> x2 # The dimension with the "number of steps"
array([[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.],
[ 1., 4., 7., 10.]])
You specifically asked about the purpose and in fact, these grids are extremely useful if you need a coordinate system.
For example if you have a NumPy function that calculates the distance in two dimensions:
def distance_2d(x_point, y_point, x, y):
return np.hypot(x-x_point, y-y_point)
And you want to know the distance of each point:
>>> ys, xs = np.ogrid[-5:5, -5:5]
>>> distances = distance_2d(1, 2, xs, ys) # distance to point (1, 2)
>>> distances

The output would be identical if one passed in a dense grid instead of an open grid. NumPys broadcasting makes it possible!
Let's visualize the result:
plt.figure()
plt.title('distance to point (1, 2)')
plt.imshow(distances, origin='lower', interpolation="none")
plt.xticks(np.arange(xs.shape[1]), xs.ravel()) # need to set the ticks manually
plt.yticks(np.arange(ys.shape[0]), ys.ravel())
plt.colorbar()
And this is also when NumPys mgrid and ogrid become very convenient because it allows you to easily change the resolution of your grids:
ys, xs = np.ogrid[-5:5:200j, -5:5:200j]
# otherwise same code as above
However, since imshow doesn't support x and y inputs one has to change the ticks by hand. It would be really convenient if it would accept the x and y coordinates, right?
It's easy to write functions with NumPy that deal naturally with grids. Furthermore, there are several functions in NumPy, SciPy, matplotlib that expect you to pass in the grid.
I like images so let's explore matplotlib.pyplot.contour:
ys, xs = np.mgrid[-5:5:200j, -5:5:200j]
density = np.sin(ys)-np.cos(xs)
plt.figure()
plt.contour(xs, ys, density)
Note how the coordinates are already correctly set! That wouldn't be the case if you just passed in the density.
Or to give another fun example using astropy models (this time I don't care much about the coordinates, I just use them to create some grid):
from astropy.modeling import models
z = np.zeros((100, 100))
y, x = np.mgrid[0:100, 0:100]
for _ in range(10):
g2d = models.Gaussian2D(amplitude=100,
x_mean=np.random.randint(0, 100),
y_mean=np.random.randint(0, 100),
x_stddev=3,
y_stddev=3)
z += g2d(x, y)
a2d = models.AiryDisk2D(amplitude=70,
x_0=np.random.randint(0, 100),
y_0=np.random.randint(0, 100),
radius=5)
z += a2d(x, y)
Although that's just "for the looks" several functions related to functional models and fitting (for example scipy.interpolate.interp2d,
scipy.interpolate.griddata even show examples using np.mgrid) in Scipy, etc. require grids. Most of these work with open grids and dense grids, however some only work with one of them.
I had to use Take(n) method, then transform to list, Worked like a charm:
var listTest = (from x in table1
join y in table2
on x.field1 equals y.field1
orderby x.id descending
select new tempList()
{
field1 = y.field1,
active = x.active
}).Take(10).ToList();
What is the purpose of this
names = list;
? Also, no ; required in Python.
Do you want
names = []
or
names = list()
at the start of your program instead? Though given your particular code, there's no need for this statement to create this names variable since you do so later when you read data into it from your file.
@JBernardo has already pointed out the other (and more major) problem with the code.
uint8, uint16, uint32, and uint64 are probably Microsoft-specific types.
As of the 1999 standard, C supports standard typedefs with similar meanings, defined in <stdint.h>: uint8_t, uint16_t, uint32_t, and uint64_t. I'll assume that the Microsoft-specific types are defined similarly. Microsoft does support <stdint.h>, at least as of Visual Studio 2010, but older code may use uint8 et al.
The predefined types char, short, int et al have sizes that vary from one C implementation to another. The C standard has certain minimum requirements (char is at least 8 bits, short and int are at least 16, long is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int is 16, 32, or 64 bits.
char is almost always exactly 8 bits, but it's permitted to be wider. And plain char may be either signed or unsigned.
uint8_t is required to be an unsigned integer type that's exactly 8 bits wide. It's likely to be a typedef for unsigned char, though it might be a typedef for plain char if plain char happens to be unsigned. If there is no predefined 8-bit unsigned type, then uint8_t will not be defined at all.
Similarly, each uintN_t type is an unsigned type that's exactly N bits wide.
In addition, <stdint.h> defines corresponding signed intN_t types, as well as int_fastN_t and int_leastN_t types that are at least the specified width.
The [u]intN_t types are guaranteed to have no padding bits, so the size of each is exactly N bits. The signed intN_t types are required to use a 2's-complement representation.
Although uint32_t might be the same as unsigned int, for example, you shouldn't assume that. Use unsigned int when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t when you need an unsigned integer type that's exactly 32 bits wide.
(And no, uint64 or uint64_t is not the same as double; double is a floating-point type.)
There are plenty available. Try using Modal windows of Jquery or DHTML would do good. Put the content in your div or Change your content in div dynamically and show it to the user. It won't be a popup but a modal window.
Jquery's Thickbox would clear your problem.
Another attempt at explaining monads, using just Python lists and the map function. I fully accept this isn't a full explanation, but I hope it gets at the core concepts.
I got the basis of this from the funfunfunction video on Monads and the Learn You A Haskell chapter 'For a Few Monads More'. I highly recommend watching the funfunfunction video.
At it's very simplest, Monads are objects that have a map and flatMap functions (bind in Haskell). There are some extra required properties, but these are the core ones.
flatMap 'flattens' the output of map, for lists this just concatenates the values of the list e.g.
concat([[1], [4], [9]]) = [1, 4, 9]
So in Python we can very basically implement a Monad with just these two functions:
def flatMap(func, lst):
return concat(map(func, lst))
def concat(lst):
return sum(lst, [])
func is any function that takes a value and returns a list e.g.
lambda x: [x*x]
For clarity I created the concat function in Python via a simple function, which sums the lists i.e. [] + [1] + [4] + [9] = [1, 4, 9] (Haskell has a native concat method).
I'm assuming you know what the map function is e.g.:
>>> list(map(lambda x: [x*x], [1,2,3]))
[[1], [4], [9]]
Flattening is the key concept of Monads and for each object which is a Monad this flattening allows you to get at the value that is wrapped in the Monad.
Now we can call:
>>> flatMap(lambda x: [x*x], [1,2,3])
[1, 4, 9]
This lambda is taking a value x and putting it into a list. A monad works with any function that goes from a value to a type of the monad, so a list in this case.
That's your monad defined.
I think the question of why they're useful has been answered in other questions.
Other examples that aren't lists are JavaScript Promises, which have the then method and JavaScript Streams which have a flatMap method.
So Promises and Streams use a slightly different function which flattens out a Stream or a Promise and returns the value from within.
The Haskell list monad has the following definition:
instance Monad [] where
return x = [x]
xs >>= f = concat (map f xs)
fail _ = []
i.e. there are three functions return (not to be confused with return in most other languages), >>= (the flatMap) and fail.
Hopefully you can see the similarity between:
xs >>= f = concat (map f xs)
and:
def flatMap(f, xs):
return concat(map(f, xs))

On iOS there is the switch UI component instead of a checkbox, look into the UISwitch class.
The property on (boolean) can be used to determine the state of the slider and about the saving of its state: That depends on how you save your other stuff already, its just saving a boolean value.
You can use the folowing code:
def float_range(initVal, itemCount, step):
for x in xrange(itemCount):
yield initVal
initVal += step
[x for x in float_range(1, 3, 0.1)]
{{ path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) }}
If you want to read it into a view variable:
{% set currentPath = path(app.request.attributes.get('_route'),
app.request.attributes.get('_route_params')) %}
The app global view variable contains all sorts of useful shortcuts, such as app.session and app.security.token.user, that reference the services you might use in a controller.
You can also set this directly from Interface Builder under the Attributes Inspector.

public int GetHighestValue(List<MyTypes> list)
{
return list.Count > 0 ? list.Max(t => t.Age) : 0; //could also return -1
}
This is also possible with a Dictionary
using System.Linq;
public int GetHighestValue(Dictionary<MyTypes, OtherType> obj)
{
return obj.Count > 0 ? obj.Max(t => t.Key.Age) : 0; //could also return -1
}
Try
System.exit(0);
this should terminate thread main and end the main program
This can also be done freely online: http://www.showmycode.com/
EDIT A quick Google search turned up this list, which probably has all the tools you could possibly want (look at the comments as well): http://bruce-lab.blogspot.co.il/2010/08/freeswfdecompilers.html
A Date object has no format, it is a representation. The date can be presented by a String with the format you like.
E.g. "yyyy-MM-dd", "yy-MMM-dd", "dd-MMM-yy" and etc.
To acheive this you can get the use of the SimpleDateFormat
Try this,
String inputString = "19/05/2009"; // i.e. (dd/MM/yyyy) format
SimpleDateFormat fromUser = new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat myFormat = new SimpleDateFormat("yyyy-MM-dd");
try {
Date dateFromUser = fromUser.parse(inputString); // Parse it to the exisitng date pattern and return Date type
String dateMyFormat = myFormat.format(dateFromUser); // format it to the date pattern you prefer
System.out.println(dateMyFormat); // outputs : 2009-05-19
} catch (ParseException e) {
e.printStackTrace();
}
This outputs : 2009-05-19
On top of all the previous answers, dont forget to hide your alert before using it with a simple style="display:none;"
<div class="alert alert-success" id="passwordsNoMatchRegister" role="alert" style="display:none;" >Message of the Alert</div>
Then use either:
$('#passwordsNoMatchRegister').show();
$('#passwordsNoMatchRegister').fadeIn();
$('#passwordsNoMatchRegister').slideDown();

The following solution is different to the ones proposed so far, and works for me.
The rationale is that you select all matching children first, and then filter out the ones which are not direct children. A child is a direct child if it does not have a matching parent with the same selector.
function queryDirectChildren(parent, selector) {
const nodes = parent.querySelectorAll(selector);
const filteredNodes = [].slice.call(nodes).filter(n =>
n.parentNode.closest(selector) === parent.closest(selector)
);
return filteredNodes;
}
HTH!
When you say
(a['x']==1) and (a['y']==10)
You are implicitly asking Python to convert (a['x']==1) and (a['y']==10) to boolean values.
NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a boolean value -- in other words, they raise
ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all().
when used as a boolean value. That's because its unclear when it should be True or False. Some users might assume they are True if they have non-zero length, like a Python list. Others might desire for it to be True only if all its elements are True. Others might want it to be True if any of its elements are True.
Because there are so many conflicting expectations, the designers of NumPy and Pandas refuse to guess, and instead raise a ValueError.
Instead, you must be explicit, by calling the empty(), all() or any() method to indicate which behavior you desire.
In this case, however, it looks like you do not want boolean evaluation, you want element-wise logical-and. That is what the & binary operator performs:
(a['x']==1) & (a['y']==10)
returns a boolean array.
By the way, as alexpmil notes,
the parentheses are mandatory since & has a higher operator precedence than ==.
Without the parentheses, a['x']==1 & a['y']==10 would be evaluated as a['x'] == (1 & a['y']) == 10 which would in turn be equivalent to the chained comparison (a['x'] == (1 & a['y'])) and ((1 & a['y']) == 10). That is an expression of the form Series and Series.
The use of and with two Series would again trigger the same ValueError as above. That's why the parentheses are mandatory.
Ayman is right but, you can use it like that as well :
if( $("#field > div.field-item").text().indexOf('someText') >= 0) {
$("#somediv").addClass("thisClass");
}
Use Not IsNull(Fields!W_O_Count.Value)
I managed to stop the video using "get(0)" (Retrieve the DOM elements matched by the jQuery object):
$("#closeSimple").click(function() {
$("div#simpleModal").removeClass("show");
$("#videoContainer").get(0).pause();
return false;
});
Open command prompt in the root folder of your project and run below command:
php artisan key:generate
It will generate Application Key for your application.
You can find the generated application key(APP_KEY) in .env file.
if(data.trim()==''){alert("Nothing Found");}
For some reason, radhoo's solution wouldn't work for me. When I used the following expression:
$query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES (".
(($val1=='')?"NULL":("'".$val1."'")) . ", ".
(($val2=='')?"NULL":("'".$val2."'")) .
")";
'null' (with quotes) was inserted instead of null without quotes, making it a string instead of an integer. So I finally tried:
$query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES (".
(($val1=='')? :("'".$val1."'")) . ", ".
(($val2=='')? :("'".$val2."'")) .
")";
The blank resulted in the correct null (unquoted) being inserted into the query.
There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.
You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.
When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.
Fastest by far (time is in comparison to Jacobs):
clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic;
for i=1:N,
d = 1/sqrt(V(1)*V(1)+V(2)*V(2)+V(3)*V(3));
V1 = V*d;
end;
toc % 1.5s
This prints 10 lines of trailing context after matching lines
grep -i "my_regex" -A 10
If you need to print 10 lines of leading context before matching lines,
grep -i "my_regex" -B 10
And if you need to print 10 lines of leading and trailing output context.
grep -i "my_regex" -C 10
Example
user@box:~$ cat out
line 1
line 2
line 3
line 4
line 5 my_regex
line 6
line 7
line 8
line 9
user@box:~$
Normal grep
user@box:~$ grep my_regex out
line 5 my_regex
user@box:~$
Grep exact matching lines and 2 lines after
user@box:~$ grep -A 2 my_regex out
line 5 my_regex
line 6
line 7
user@box:~$
Grep exact matching lines and 2 lines before
user@box:~$ grep -B 2 my_regex out
line 3
line 4
line 5 my_regex
user@box:~$
Grep exact matching lines and 2 lines before and after
user@box:~$ grep -C 2 my_regex out

line 7
user@box:~$
Reference: manpage grep
-A num
--after-context=num
Print num lines of trailing context after matching lines.
-B num

Use Following code for redirecting on route page. Use exception.Message instide of exception. Coz exception query string gives error if it extends the querystring length.
routeData.Values.Add("error", exception.Message);
// clear error on server
Server.ClearError();
Response.RedirectToRoute(routeData.Values);
window.onload however they are often the same thing. Similarly body.onload becomes window.onload in IE.
Create custom facebook button and change visability on native facebook button:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="@+id/facebookView"
android:layout_width="300dp"
android:layout_height="48dp"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="12dp"
android:background="@drawable/btn_frame"
android:gravity="center"
android:text="@string/Sign_in_facebook_button"
android:textColor="@color/colorAccent" />
<com.facebook.login.widget.LoginButton
android:id="@+id/facebookButton"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible"
android:layout_marginBottom="12dp" />
</LinearLayout>
Add listener to your fake button and simulate click:
facebookView.setOnClickListener(this);
@Override
public void onClick(View v) {
if (v.getId() == R.id.facebookView){
facebookButton.performClick();
}
}
If you need to know the default collation for a newly created database use:
SELECT SERVERPROPERTY('Collation')
This is the server collation for the SQL Server instance that you are running.
The target container should have the white-space:pre style.
Try it below.
<script>_x000D_

var content = document.getElementById('ta').value;_x000D_
document.getElementById('target').innerText = content;_x000D_
}_x000D_

$timestamp = now();
If you want a unix timestamp, you can also try this:
$unix_timestamp = now()->timestamp;
Please check this example here: Accessing Structure Members
There is explained that the right way to do it is like this:
strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);
If you are using a non default MySQL port number then do the following:
33747 then paste the following
$cfg['Servers'][$i]['port'] = 33747;

I had the same question. This works great in Wordpress!
<a href="//pinterest.com/pin/create/link/?url=<?php the_permalink();?>&description=<?php the_title();?>">Pin this</a>
You can solve this by finding
ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_520_ci;
in your .sql file, and swapping it with
ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci;
You can use the .not() method or :not() selector
Code based on your example:
$("ul#list li").not(".active") // not method
$("ul#list li:not(.active)") // not selector
Its best to use customize url approach. And its the easiest. Found this one. It will open a popup window and you dont need any bs authentication issues because of w_share and all.

You should first consider making GetStringData an async method and have it await the task returned from MyAsyncMethod.
If you're absolutely sure that you don't need to handle exceptions from MyAsyncMethod or know when it completes, then you can do this:
public string GetStringData()
{
var _ = MyAsyncMethod();
return "hello world";
}
BTW, this is not a "common problem". It's very rare to want to execute some code and not care whether it completes and not care whether it completes successfully.
Update:
Since you're on ASP.NET and wanting to return early, you may find my blog post on the subject useful. However, ASP.NET was not designed for this, and there's no guarantee that your code will run after the response is returned. ASP.NET will do its best to let it run, but it can't guarantee it.
So, this is a fine solution for something simple like tossing an event into a log where it doesn't really matter if you lose a few here and there. It's not a good solution for any kind of business-critical operations. In those situations, you must adopt a more complex architecture, with a persistent way to save the operations (e.g., Azure Queues, MSMQ) and a separate background process (e.g., Azure Worker Role, Win32 Service) to process them.
You can use nested query to get that, like below one is explained for the third max salary. Every nested salary is giving you the highest one with the filtered where result and at the end it will return you exact 3rd highest salary irrespective of number of records for the same salary.
select * from users where salary < (select max(salary) from users where salary < (select max(salary) from users)) order by salary desc limit 1
OK, the following answer is slightly beyond-scope if you only care about Python 3, but this question is the first Google hit even if you don't specify the Python version, so here's a way that works on both Python 2 and Python 3.
I'm also interpreting the question to be about converting bytes to the str type: that is, bytes-y on Python 2, and Unicode-y on Python 3.
Given that, the best approach I know is:
import six
bytes_to_hex_str = lambda b: ' '.join('%02x' % i for i in six.iterbytes(b))
The following assertion will be true for either Python 2 or Python 3, assuming you haven't activated the unicode_literals future in Python 2:
assert bytes_to_hex_str(b'jkl') == '6a 6b 6c'
(Or you can use ''.join() to omit the space between the bytes, etc.)
In IntelliJ Idea 2019 you can find scope "Problems" under the "Project" view. Default scope is "Project".
You can use as well VB .NET syntax:
=DateTime.Now.ToString("MM/dd/yyyy hh:mm tt")
You should be able to use the Clear() method.
the best of the best way is:
var floatNumber = 12.5523;
var x = floatNumber - Math.Truncate(floatNumber);
result you can convert however you like
You can get any file mime type with getContentResolver().getType(uri):
protected static void openFile(Context context, Uri localUri){
Intent i = new Intent(Intent.ACTION_VIEW);
i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
i.setDataAndType(localUri, context.getContentResolver().getType(localUri));
context.startActivity(i);
}
I have not spent the time to make 100% certain, but it worked for my inputs enough to be accepted by online JSON validators:
org.apache.velocity.tools.generic.EscapeTool.EscapeTool().java("input")
although it does not look any better than org.codehaus.jettison.json.JSONObject.quote("your string")
I simply use velocity tools in my project already - my "manual JSON" building was within a velocity template
Sometimes when you have multiple classes and you really need to overwrite all of them, it's easiest to use jQuery's .attr() to overwrite the class attribute:
$('#myElement').attr('class', 'new-class1 new-class2 new-class3');
for getting Hash map first element you can use bellow code in kotlin:
val data : Float = hashMap?.get(hashMap?.keys?.first())
escapeRegExp = function(str) {
if (str == null) return '';
return String(str).replace(/([.*+?^=!:${}()|[\]\/\\])/g, '\\$1');
};
I ran into the same. Saw an example using this: https://github.com/flesler/jquery.scrollTo
I use it as follows:
$('#arrow_back').click(function () {
$.scrollTo('#features_1', 1000, { easing: 'easeInOutExpo', offset: 0, 'axis': 'y' });
});
Clean solution. Works for me!
We started finding some machines with IE 11 not playing video (via flash) after we set the emulation mode of our app (web browser control) to 110001. Adding the meta tag to our htm files worked for us.
my @array = stat($filehandle);
The modification time is stored in Unix format in $array[9].
Or explicitly:
my ($dev, $ino, $mode, $nlink, $uid, $gid, $rdev, $size,
$atime, $mtime, $ctime, $blksize, $blocks) = stat($filepath);
0 dev Device number of filesystem
1 ino inode number
2 mode File mode (type and permissions)
3 nlink Number of (hard) links to the file
4 uid Numeric user ID of file's owner
5 gid Numeric group ID of file's owner
6 rdev The device identifier (special files only)
7 size Total size of file, in bytes
8 atime Last access time in seconds since the epoch
9 mtime Last modify time in seconds since the epoch
10 ctime inode change time in seconds since the epoch
11 blksize Preferred block size for file system I/O
12 blocks Actual number of blocks allocated
The epoch was at 00:00 January 1, 1970 GMT.
More information is in stat.
You should not use bash in this case to get rid of the output. Yum does have an option -q which suppresses the output.
You'll most certainly also want to use -y
echo "Installing nano..."
yum -y -q install nano
To see all the options for yum, use man yum.
Wikipedia never lets down:
jars use zip compression so you can use any unzip utility.
Example:
$ unzip myJar.jar -d ./directoryToExtractTo
The easiest way is probably to check the PATH environment variable of the process that is connecting to the database. Most likely the tnsnames.ora file is in first Oracle bin directory in path..\network\admin. TNS_ADMIN environment variable or value in registry (for the current Oracle home) may override this.
Using filemon like suggested by others will also do the trick.
Why not use a regular expression ?
public static boolean toBoolean( String target )
{
if( target == null ) return false;
return target.matches( "(?i:^(1|true|yes|oui|vrai|y)$)" );
}
@param will not affect testNumber.It is a Javadoc comment - i.e used for generating documentation .
You can put a Javadoc comment immediately before a class, field, method, constructor, or interface such as @param, @return .
Generally begins with '@' and must be the first thing on the line.
The Advantage of using @param is :-
By creating simple Java classes that contain attributes and some custom Javadoc tags, you allow those classes to serve as a simple metadata description for code generation.
/*
*@param testNumber
*@return integer
*/
public int main testNumberIsValid(int testNumber){
if (testNumber < 6) {
//Something
}
}
Whenever in your code if you reuse testNumberIsValid method, IDE will show you the parameters the method accepts and return type of the method.
In a google script project you can create html files (example: index.html) or gs files (example:code.gs). The .gs files are executed on the server and you can use Logger.log as @Peter Herrman describes. However if the function is created in a .html file it is being executed on the user's browser and you can use console.log. The Chrome browser console can be viewed by Ctrl Shift J on Windows/Linux or Cmd Opt J on Mac
If you want to use Logger.log on an html file you can use a scriptlet to call the Logger.log function from the html file. To do so you would insert <? Logger.log(something) ?> replacing something with whatever you want to log. Standard scriptlets, which use the syntax <? ... ?>, execute code without explicitly outputting content to the page.
As an exercise, I would suggest doing the following:
public void save(String fileName) throws FileNotFoundException {
PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
for (Club club : clubs)
pw.println(club.getName());
pw.close();
}
This will write the name of each club on a new line in your file.
Soccer Chess Football Volleyball ...
I'll leave the loading to you. Hint: You wrote one line at a time, you can then read one line at a time.
Every class in Java extends the Object class. As such you can override its methods. In this case, you should be interested by the toString() method. In your Club class, you can override it to print some message about the class in any format you'd like.
public String toString() {
return "Club:" + name;
}
You could then change the above code to:
public void save(String fileName) throws FileNotFoundException {
PrintWriter pw = new PrintWriter(new FileOutputStream(fileName));
for (Club club : clubs)
pw.println(club); // call toString() on club, like club.toString()
pw.close();
}
I had the same need in bash (Ubuntu 16.04 LTS) and the commands provided in the answers failed to work in my case. I had to use:
curl -X POST -F 'username="$USER"' -F 'password="$PASS"' "http://api.somesite.com/test/blah?something=123"
Double quotes in the -F arguments are only needed if you're using variables, thus from the command line ... -F 'username=myuser' ... will be fine.
Relevant Security Notice: as Mr. Mark Ribau points in comments this command shows the password ($PASS variable, expanded) in the processlist!
For setting the input type for an EditText programmatically, you have to specify that input class type is text.
editPass.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
If you are looking for Swift 3, Follow the steps to achieve this:
func viewDidLoad() {
//Define Layout here
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
//Get device width
let width = UIScreen.main.bounds.width
//set section inset as per your requirement.
layout.sectionInset = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
//set cell item size here
layout.itemSize = CGSize(width: width / 2, height: width / 2)
//set Minimum spacing between 2 items
layout.minimumInteritemSpacing = 0
//set minimum vertical line spacing here between two lines in collectionview
layout.minimumLineSpacing = 0
//apply defined layout to collectionview
collectionView!.collectionViewLayout = layout
}
This is verified on Xcode 8.0 with Swift 3.

You could use a literal eval:
>>> ast.literal_eval('0xdeadbeef')
3735928559
Or just specify the base as argument to int:
>>> int('deadbeef', 16)
3735928559
A trick that is not well known, if you specify the base 0 to int, then Python will attempt to determine the base from the string prefix:
>>> int("0xff", 0)
255
>>> int("0o644", 0)
420
>>> int("0b100", 0)
4
>>> int("100", 0)
100
I had a false response for the following:
fputs($connection, 'STARTTLS'.$newLine);
turns out I use the wrong connection variable, so I just had to change it to:
fputs($smtpConnect, 'STARTTLS'.$newLine);
If using TLS remember to put HELO before and after:
fputs($smtpConnect, 'HELO '.$localhost . $newLine);
$response = fgets($smtpConnect, 515);
if($secure == 'tls')
{
fputs($smtpConnect, 'STARTTLS'.$newLine);
$response = fgets($smtpConnect, 515);
stream_socket_enable_crypto($smtpConnect, true, STREAM_CRYPTO_METHOD_TLS_CLIENT);
// Say hello again!
fputs($smtpConnect, 'HELO '.$localhost . $newLine);
$response = fgets($smtpConnect, 515);
}
as an alternative syntax you can write foreach loops like so
foreach($arr as $item):
//do stuff
endforeach;
This type of syntax is typically used when php is being used as a templating language as such
<?php foreach($arr as $item):?>
<!--do stuff -->
<?php endforeach; ?>
The PHP way to do it is using the function parse_url, which parses a URL and return its components. Including the query string.
Example:
$url = 'www.mysite.com/category/subcategory?myqueryhash';
echo parse_url($url, PHP_URL_QUERY); # output "myqueryhash"
Hide the body with css then show it after the page is loaded:
CSS:
html { visibility:hidden; }
Javascript
$(document).ready(function() {
document.getElementsByTagName("html")[0].style.visibility = "visible";
});
The page will go from blank to showing all content when the page is loaded, no flash of content, no watching images load etc.
IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.

then install then follow instructions as per this page: https://cyleft.wordpress.com/2008/07/20/fixing-mysql-service-could-not-start-1067-errors/
For HTTP Basic Auth:
curl -H "Authorization: Basic <_your_token_>" http://www.example.com
replace _your_token_ and the URL.
Clarification Here:
While this will work:
JsonNode rootNode = objectMapper.readTree(file);
Iterator<Map.Entry<String, JsonNode>> fields = rootNode.fields();
while (fields.hasNext()) {
Map.Entry<String, JsonNode> entry = fields.next();
log.info(entry.getKey() + ":" + entry.getValue())
}
This will not:
JsonNode rootNode = objectMapper.readTree(file);
while (rootNode.fields().hasNext()) {
Map.Entry<String, JsonNode> entry = rootNode.fields().next();
log.info(entry.getKey() + ":" + entry.getValue())
}
So be careful to declare the Iterator as a variable and use that.
Be sure to use the fasterxml library rather than codehaus.
This is a simple word counter using regex. The script includes a loop which you can terminate it when you're done.
#word counter using regex
import re
while True:
string =raw_input("Enter the string: ")
count = len(re.findall("[a-zA-Z_]+", string))
if line == "Done": #command to terminate the loop
break
print (count)
print ("Terminated")
@David Conrad solution is the fastest I tried using the Normalizer, but it does have a bug. It basically strips characters which are not accents, for example Chinese characters and other letters like æ, are all stripped. The characters that we want to strip are non spacing marks, characters which don't take up extra width in the final string. These zero width characters basically end up combined in some other character. If you can see them isolated as a character, for example like this `, my guess is that it's combined with the space character.
public static String flattenToAscii(String string) {
char[] out = new char[string.length()];
String norm = Normalizer.normalize(string, Normalizer.Form.NFD);
int j = 0;
for (int i = 0, n = norm.length(); i < n; ++i) {
char c = norm.charAt(i);
int type = Character.getType(c);
//Log.d(TAG,""+c);
//by Ricardo, modified the character check for accents, ref: http://stackoverflow.com/a/5697575/689223
if (type != Character.NON_SPACING_MARK){
out[j] = c;
j++;
}
}
//Log.d(TAG,"normalized string:"+norm+"/"+new String(out));
return new String(out);
}
By forking SPLITS repo, I built one to test iOS memory that can be allocated to the Today's Extension
iOSMemoryBudgetTestForExtension
Following is the result that i got in iPhone 5s
Memory Warning at 10 MB
App Crashed at 12 MB
By this means Apple is merely allowing any extensions to work with their full potential.
I found there's one reason for this problem: not enough space on mobile. So I delete several APP from mobile and it's fixed.
The $innerListItem.position().top is actually relative to the .scrollTop() of its first positioned ancestor. So the way to calculate the correct $parentDiv.scrollTop() value is to begin by making sure that $parentDiv is positioned. If it doesn't already have an explicit position, use position: relative. The elements $innerListItem and all its ancestors up to $parentDiv need to have no explicit position. Now you can scroll to the $innerListItem with:
// Scroll to the top
$parentDiv.scrollTop($parentDiv.scrollTop() + $innerListItem.position().top);
// Scroll to the center
$parentDiv.scrollTop($parentDiv.scrollTop() + $innerListItem.position().top
- $parentDiv.height()/2 + $innerListItem.height()/2);
Just use this one, You have to use more when they are classes.

it is a very old thread, I know but this might help too if somebody gets here once they search for a solution.
Basically I used the document.currentScript to get the element from where my code is running and I filter using the name of the variable I am looking for. I did it extending currentScript with a method called "get", so we will be able to fetch the value inside that script by using:
document.currentScript.get('get_variable_name');
In this way we can use standard URI to retrieve the variables without adding special attributes.
This is the final code
document.currentScript.get = function(variable) {
if(variable=(new RegExp('[?&]'+encodeURIComponent(variable)+'=([^&]*)')).exec(this.src))
return decodeURIComponent(variable[1]);
};
I was forgetting about IE :) It could not be that easier... Well I did not mention that document.currentScript is a HTML5 property. It has not been included for different versions of IE (I tested until IE11, and it was not there yet). For IE compatibility, I added this portion to the code:
document.currentScript = document.currentScript || (function() {
var scripts = document.getElementsByTagName('script');
return scripts[scripts.length - 1];
})();
What we are doing here is to define some alternative code for IE, which returns the current script object, which is required in the solution to extract parameters from the src property. This is not the perfect solution for IE since there are some limitations; If the script is loaded asynchronously. Newer browsers should include ".currentScript" property.
I hope it helps.
For me the error was the files under js folder not included in the project this solve my issue :
1- In the solution explorer toolbar click Show All Files.
2- open js folder and select all files under the folder
3- right click then select include In Project
4- Save and build your application then its working correct and load .css and .js files
kill the java (TM) process from processes in you computer. re-run mvn cmd . It should work now.
For Redhat Versions(Centos 7) Use the below command to install Python Development Package
Python 2.7
sudo yum install python-dev
Python 3.4
sudo yum install python34-devel
If the issue is still not resolved then try installing the below packages -
sudo yum install python-devel
sudo yum install openssl-devel
sudo yum install libffi-devel
Use the context-parameter
$("#testdiv",parent.document)
But if you really use a popup, you need to access opener instead of parent
$("#testdiv",opener.document)
The number in parentheses in a type declaration is display width, which is unrelated to the range of values that can be stored in a data type. Just because you can declare Int(20) does not mean you can store values up to 10^20 in it:
[...] This optional display width may be used by applications to display integer values having a width less than the width specified for the column by left-padding them with spaces. ...
The display width does not constrain the range of values that can be stored in the column, nor the number of digits that are displayed for values having a width exceeding that specified for the column. For example, a column specified as SMALLINT(3) has the usual SMALLINT range of -32768 to 32767, and values outside the range allowed by three characters are displayed using more than three characters.
For a list of the maximum and minimum values that can be stored in each MySQL datatype, see here.
All the existing answers only work from the sqlite command line, which isn't ideal if you'd like to build a reusable script. Python makes it easy to build a script that can be executed programatically.
import pandas as pd
import sqlite3
conn = sqlite3.connect('your_cool_database.sqlite')
df = pd.read_sql('SELECT * from orders', conn)
df.to_csv('orders.csv', index = False)
You can customize the query to only export part of the sqlite table to the CSV file.
You can also run a single command to export all sqlite tables to CSV files:
for table in c.execute("SELECT name FROM sqlite_master WHERE type='table';").fetchall():
t = table[0]
df = pd.read_sql('SELECT * from ' + t, conn)
df.to_csv(t + '_one_command.csv', index = False)
See here for more info.

I faced the same issue. When I tried to run the project from IDE, it was giving me same error. But when I tried running from the command prompt, the project was running fine. So it came to me that there should be some issue with the settings that makes the program to Run from IDE.
I solved the problem by changing some Project settings. I traced the error and came to the following part in my pom.xml file.
<execution>
<id>default-cli</id>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>${java.home}/bin/java</executable>
<commandlineArgs>${runfx.args}</commandlineArgs>
</configuration>
</execution>
I went to my Project Properties > Actions Categories > Action: Run Project: then I Set Properties for Run Project Action as follows:
runfx.args=-jar "${project.build.directory}/${project.build.finalName}.jar"
Then, I rebuild the project and I was able to Run the Project. As you can see, the IDE(Netbeans in my case), was not able to find 'runfx.args' which is set in Project Properties.
Use require function when you need to load any class, function, or dependency.
Use include function when you want to load template-styled file
If you are still confused, just use require_once for all time.
The use of -X [WHATEVER] merely changes the request's method string used in the HTTP request. This is easier to understand with two examples — one with -X [WHATEVER] and one without — and the associated HTTP request headers for each:

This was written quickly, and is neither pretty nor efficient (plus it autoboxes alot, converting between int and Integer is annoying!), but it works.
It probably breaks the rules since I'm creating my own objects but hey I'm doing this as a diversion from real work :)
This also assumes that the resultSet/table is completely read into some sort of structure before you start building Nodes, which wouldn't be the best solution if you have hundreds of thousands of rows.
public class Node {
private Node parent = null;

// create special 'root' Node with id=0
Node root = new Node(null, 0, "root");
nodeMap.put(root.getId(), root);

It seems that you can use the repository browser. Click the revision button at top-right and change it to the revision you want. Then right-click your file in the browser and use 'Copy to working copy...' but change the filename it will check out, to avoid a clash.
From ?factor:
To transform a factor f to approximately its original numeric values,
as.numeric(levels(f))[f]is recommended and slightly more efficient thanas.numeric(as.character(f)).
The Problem Occur Because the application I was using and the dll i added to my application both have different Versions.
Add this Package- Install-Package Microsoft.Bcl.Async -Version 1.0.168
ADDING THIS PACKAGE async Code becomes Compatible in version 4.0 as well, because Async only work on applications whose Versions are more than or equal to 4.5
I had the same issue. Combining various approaches from the internet (and above) come up with the following approach (checkEmails.py)
class CheckMailer:
def __init__(self, filename="LOG1.txt", mailbox="Mailbox - Another User Mailbox", folderindex=3):
self.f = FileWriter(filename)
self.outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI").Folders(mailbox)
self.inbox = self.outlook.Folders(folderindex)
def check(self):
#===============================================================================
# for i in xrange(1,100): #Uncomment this section if index 3 does not work for you
# try:
# self.inbox = self.outlook.Folders(i) # "6" refers to the index of inbox for Default User Mailbox
# print "%i %s" % (i,self.inbox) # "3" refers to the index of inbox for Another user's mailbox
# except:
# print "%i does not work"%i
#===============================================================================
self.f.pl(time.strftime("%H:%M:%S"))
tot = 0
messages = self.inbox.Items
message = messages.GetFirst()
while message:
self.f.pl (message.Subject)
message = messages.GetNext()
tot += 1
self.f.pl("Total Messages found: %i" % tot)
self.f.pl("-" * 80)
self.f.flush()
if __name__ == "__main__":
mail = CheckMailer()
for i in xrange(320): # this is 10.6 hours approximately
mail.check()
time.sleep(120.00)
For concistency I include also the code for the FileWriter class (found in FileWrapper.py). I needed this because trying to pipe UTF8 to a file in windows did not work.
class FileWriter(object):
'''

'''
def __init__(self, filename):
'''
Constructor
'''
self.file = open(filename, "w")
def pl(self, a_string):
str_uni = a_string.encode('utf-8')
self.file.write(str_uni)
self.file.write("\n")
def flush(self):
self.file.flush()
If that helps anyone, (even if this is kind of poor as we must only allow this for dev purpose) here is a Java solution as I encountered the same issue.
[Edit] Do not use the wild card * as it is a bad solution, use localhost if you really need to have something working locally.

As of https://github.com/dotnet/coreclr/pull/14863, there is a new way to generate hash codes that is super simple! Just write
public override int GetHashCode()
=> HashCode.Combine(field1, field2, field3);
This will generate a quality hash code without you having to worry about the implementation details.
the problem is in the MatInputModule:
exports: [
MatInputModule
]
Though weirdly named, you can use the getimagesize() function. This will also give you mime information:
Array
(
[0] => 295 // width
[1] => 295 // height
[2] => 3 // http://php.net/manual/en/image.constants.php
[3] => width="295" height="295" // width and height as attr's
[bits] => 8
[mime] => image/png
)
On Mac, If you have a problem in logging in with the first password you were given in installation, maybe you can just simply kill the mysql process and then try.
So: 1- run the following command to find the PID of mysql:
ps -aef | grep mysql | grep -v grep
2- kill the process:
kill -15 [process id]
Then you can login with the initial password using this command:
mysql -uroot -p
Which ask you to enter your password. Just enter the initial password.
Sheet1.Range("myrange").Rows.Count
On MySQL 5.7 and Ubuntu 16.04, edit the file mysql.cnf.
$ sudo nano /etc/mysql/conf.d/mysql.cnf
Include the sql_mode like the following and save the file.
[mysql]
sql_mode=IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
Observe that, in my case, I removed the mode STRICT_TRANS_TABLES and the ONLY_FULL_GROUP_BY.
Doing this, it will save the mode configuration permanently. Differently if you just update the @@sql_mode through MySQL, because it will reset on machine/service restart.
After that, to the modified configuration take in action, restart the mysql service:
$ sudo service mysql restart
Try to access the mysql:
$ mysql -u user_name -p
If you are able to login and access MySQL console, it is ok. Great!
BUT, if like me, you face the error "unknown variable sql_mode", which indicates that sql_mode is an option for mysqld, you will have to go back, edit the file mysql.cnf again and change the [mysql] to [mysqld]. Restart the MySQL service and do a last test trying to login on MySQL console. Here it is!
The best (and easiest) way to copy data from a workbook to another is to use the object model of Excel.
Option Explicit
Sub test()
Dim wb As Workbook, wb2 As Workbook
Dim ws As Worksheet
Dim vFile As Variant
'Set source workbook
Set wb = ActiveWorkbook
'Open the target workbook
vFile = Application.GetOpenFilename("Excel-files,*.xls", _
1, "Select One File To Open", , False)
'if the user didn't select a file, exit sub
If TypeName(vFile) = "Boolean" Then Exit Sub
Workbooks.Open vFile
'Set targetworkbook
Set wb2 = ActiveWorkbook
'For instance, copy data from a range in the first workbook to another range in the other workbook
wb2.Worksheets("Sheet2").Range("C3:D4").Value = wb.Worksheets("Sheet1").Range("A1:B2").Value
End Sub
JavaScript uses the \ (backslash) as an escape characters for:
Note that the \v and \0 escapes are not allowed in JSON strings.
JQUery has a .parents() method for moving up the DOM tree you can start there.
If you're interested in doing this a more semantic way I don't think using the REL attribute on a button is the best way to semantically define "this is the answer" in your code. I'd recommend something along these lines:
<p id="question1">
<label for="input1">Volume =</label>
<input type="text" name="userInput1" id="userInput1" />
<button type="button">Check answer</button>
<input type="hidden" id="answer1" name="answer1" value="3.93e-6" />
</p>
and
$("button").click(function () {
var correctAnswer = $(this).parent().siblings("input[type=hidden]").val();
var userAnswer = $(this).parent().siblings("input[type=text]").val();
validate(userAnswer, correctAnswer);
$("#messages").html(feedback);
});
Not quite sure how your validate and feedback are working, but you get the idea.
If you are using Visual Studio, there is a GUI solution as well:
In your example, wc is a local variable which will be deallocated when the function call ends. This puts you into undefined behavior territory.
The simple fix is this:
const wchar_t *GetWC(const char *c)
{
const size_t cSize = strlen(c)+1;
wchar_t* wc = new wchar_t[cSize];
mbstowcs (wc, c, cSize);
return wc;
}
Note that the calling code will then have to deallocate this memory, otherwise you will have a memory leak.
I tried this and worked for me.
success: function (response) {
document.getElementById('packageItems').value = response.package_items;
ClassicEditor
.create(document.querySelector('#packageItems'), {
removePlugins: ['dragdrop']
})
.then(function (editor) {
editor.setData(response.package_items);
})
.catch(function (err) {
console.error(err);
});
},
I'm using visual studio 2015 and the solutions given above didn't work for me, so i did the following:
Delete the packages folder from my solution and also bin and obj folders from every project in the solution and give it a rebuild.
Maybe you will have the next error:

After editing @Wesley Rice's answer a couple times, I decided my changes were just getting too big to continue changing his answer instead of writing my own. So, I decided I need to write my own!
Read each line of a file in and operate on it line-by-line like this:
#!/bin/bash
input="/path/to/txt/file"
while IFS= read -r line
do
echo "$line"
done < "$input"
This comes directly from author Vivek Gite here: https://www.cyberciti.biz/faq/unix-howto-read-line-by-line-from-file/. He gets the credit!
Syntax: Read file line by line on a Bash Unix & Linux shell:
1. The syntax is as follows for bash, ksh, zsh, and all other shells to read a file line by line
2.while read -r line; do COMMAND; done < input.file
3. The-roption passed to read command prevents backslash escapes from being interpreted.
4. AddIFS=option before read command to prevent leading/trailing whitespace from being trimmed -
5.while IFS= read -r line; do COMMAND_on $line; done < input.file
And now to answer this now-closed question which I also had: Is it possible to `git add` a list of files from a file? - here's my answer:
Note that FILES_STAGED is a variable containing the absolute path to a file which contains a bunch of lines where each line is a relative path to a file I'd like to do git add on. This code snippet is about to become part of the "eRCaGuy_dotfiles/useful_scripts/sync_git_repo_to_build_machine.sh" file in this project, to enable easy syncing of files in development from one PC (ex: a computer I code on) to another (ex: a more powerful computer I build on): https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles.
while IFS= read -r line
do
echo " git add \"$line\""
git add "$line"
done < "$FILES_STAGED"
git add on it: Is it possible to `git add` a list of files from a file?As @kojiro said, you don't want to "run" this file. Source it as he says. It should get "sourced" at startup. Sourcing just means running every line in the file, including the one you want to get run. If you want to make sure a folder is in a certain path environment variable (as it seems you want from one of your comments on another solution), execute
$ echo $PATH
At the command line. If you want to check that your ~/.bash_profile is being sourced, either at startup as it should be, or when you source it manually, enter the following line into your ~/.bash_profile file:
$ echo "Hello I'm running stuff in the ~/.bash_profile!"
If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your <thead> to <caption> and remove the <td> inside of it, and then set fixed widths for the cells in <tbody>.
While you can filter Models with =, __gt, __gte, __lt, __lte, you cannot use ne or !=. However, you can achieve better filtering using the Q object.
You can avoid chaining QuerySet.filter() and QuerySet.exclude(), and use this:
from django.db.models import Q
object_list = QuerySet.filter(~Q(field='not wanted'), field='wanted')
Laravel 6 or above: just use the old() function for instance @if (old('cat')==$cat->id), it will do the rest of the work for you.
How its works: select tag store the selected option value into its name attribute in bellow case if you select any option it will store into cat. At the first time when page loaded there is nothing inside cat, when user chose a option the value of that selected option is stored into cat so when user were redirected old() function pull the previous value from cat.
{!!Form::open(['action'=>'CategoryController@storecat', 'method'=>'POST']) !!}
<div class="form-group">
<select name="cat" id="cat" class="form-control input-lg">
<option value="">Select App</option>
@foreach ($cats as $cat)
@if (old('cat')==$cat->id)
<option value={{$cat->id}} selected>{{ $cat->title }}</option>
@else
<option value={{$cat->id}} >{{ $cat->title }}</option>
@endif
@endforeach
</select>
</div>
<div class="from-group">
{{Form::label('name','Category name:')}}
{{Form::text('name','',['class'=>'form-control', 'placeholder'=>'Category name'])}}
</div>
<br>
{!!Form::submit('Submit', ['class'=>'btn btn-primary'])!!}
{!!Form::close()!!}
Probably the best reason is because 0xfffffffffffffff/15 would give you a horribly wrong answer...
In PowerShell v5.1 this is slightly different compared to v5. According to MS documentation, it has to have a -Path parameter to specify the archive file path.
Expand-Archive -Path Draft.Zip -DestinationPath C:\Reference
Or else, this can be an actual path:
Expand-Archive -Path c:\Download\Draft.Zip -DestinationPath C:\Reference

Assuming you have Manage Jenkins > Configure Global Security > Enable Security and Jenkins Own User Database checked you would go to:
ES2015 and later
In ES2015, parameter destructuring can be used to simulate named parameters. It would require the caller to pass an object, but you can avoid all of the checks inside the function if you also use default parameters:
myFunction({ param1 : 70, param2 : 175});
function myFunction({param1, param2}={}){
// ...function body...
}
// Or with defaults,
function myFunc({
name = 'Default user',
age = 'N/A'
}={}) {
// ...function body...
}
ES5
There is a way to come close to what you want, but it is based on the output of Function.prototype.toString [ES5], which is implementation dependent to some degree, so it might not be cross-browser compatible.
The idea is to parse the parameter names from the string representation of the function so that you can associate the properties of an object with the corresponding parameter.
A function call could then look like
func(a, b, {someArg: ..., someOtherArg: ...});
where a and b are positional arguments and the last argument is an object with named arguments.
For example:
var parameterfy = (function() {
var pattern = /function[^(]*\(([^)]*)\)/;
return function(func) {
// fails horribly for parameterless functions ;)
var args = func.toString().match(pattern)[1].split(/,\s*/);
return function() {
var named_params = arguments[arguments.length - 1];
if (typeof named_params === 'object') {
var params = [].slice.call(arguments, 0, -1);
if (params.length < args.length) {
for (var i = params.length, l = args.length; i < l; i++) {
params.push(named_params[args[i]]);
}
return func.apply(this, params);
}
}
return func.apply(null, arguments);
};
};
}());
Which you would use as:
var foo = parameterfy(function(a, b, c) {
console.log('a is ' + a, ' | b is ' + b, ' | c is ' + c);
});
foo(1, 2, 3); // a is 1 | b is 2 | c is 3
foo(1, {b:2, c:3}); // a is 1 | b is 2 | c is 3
foo(1, {c:3}); // a is 1 | b is undefined | c is 3
foo({a: 1, c:3}); // a is 1 | b is undefined | c is 3
There are some drawbacks to this approach (you have been warned!):
undefined (that's different from having no value at all). That means you cannot use arguments.length to test how many arguments have been passed.Instead of having a function creating the wrapper, you could also have a function which accepts a function and various values as arguments, such as
call(func, a, b, {posArg: ... });
or even extend Function.prototype so that you could do:
foo.execute(a, b, {posArg: ...});
You can resize using style and width to resize the textbox. Here is the code for it.
<!DOCTYPE html>_x000D_
<html lang="en">_x000D_
<head>_x000D_
<meta charset="UTF-8">_x000D_
_x000D_
</head>_x000D_
<body>_x000D_
<div align="center">_x000D_
_x000D_
<form method="post">_x000D_
<div class="w3-row w3-section">_x000D_
<div class="w3-rest" align = "center">_x000D_
<input name="lastName" type="text" id="myInput" style="width: 50%">_x000D_
</div>_x000D_
</div>_x000D_
</form>_x000D_
</div>_x000D_
</body>_x000D_
</html>Use align to center the textbox.
This might work:
git checkout 56e05f
echo ref: refs/heads/master > .git/HEAD
git commit
One can access each element of an array separately using the following code:
Object o=...;
if ( o.getClass().isArray() ) {
for(int i=0; i<Array.getLength(o); i++){
System.out.println(Array.get(o, i));
}
}
Notice that it is unnecessary to know what kind of underlying array it is, as this will work for any array.
You can do it multiple ways. Here are two. Cheers!
package learningjava;
public class helloworld {
public static void main(String[] args) {
new helloworld().go();
// OR
helloworld.get();
}
public void go(){
System.out.println("Hello World");
}
public static void get(){
System.out.println("Hello World, Again");
}
}
You can also create archive as usual and extract it with:
tar --strip-components 1 -xvf my_directory.tar.gz
For the given json format as in file ~/my-app/src/db/abc.json:
[
{
"name":"Ankit",
"id":1
},
{
"name":"Aditi",
"id":2
},
{
"name":"Avani",
"id":3
}
]
inorder to import to .js file like ~/my-app/src/app.js:
const json = require("./db/abc.json");
class Arena extends React.Component{
render(){
return(
json.map((user)=>
{
return(
<div>{user.name}</div>
)
}
)
}
);
}
}
export default Arena;
Output:
Ankit Aditi Avani
You can os.system function for simplicity :
import os
os.system("touch filename.extension")
This invokes system terminal to accomplish the task.
This solution produces a result list, that contains all differences from both input lists. You can compare your objects by any property, in my example it is ID. The only restriction is that the lists should be of the same type:
var DifferencesList = ListA.Where(x => !ListB.Any(x1 => x1.id == x.id))
.Union(ListB.Where(x => !ListA.Any(x1 => x1.id == x.id)));
Front :
<Image Name="camImage"/>
Back:
public async void Base64ToImage(string base64String)
{
// read stream
var bytes = Convert.FromBase64String(base64String);
var image = bytes.AsBuffer().AsStream().AsRandomAccessStream();
// decode image
var decoder = await BitmapDecoder.CreateAsync(image);
image.Seek(0);
// create bitmap
var output = new WriteableBitmap((int)decoder.PixelHeight, (int)decoder.PixelWidth);
await output.SetSourceAsync(image);
camImage.Source = output;
}
To change the title font size, use the following example
title('mytitle','FontSize',12);
to the change the graph axes label font size, do the following
axes('FontSize',24);
If your query consists only of the $where operator, you can pass in just the JavaScript expression:
db.T.find("this.Grade1 > this.Grade2");
For greater performance, run an aggregate operation that has a $redact pipeline to filter the documents which satisfy the given condition.
The $redact pipeline incorporates the functionality of $project and $match to implement field level redaction where it will return all documents matching the condition using $$KEEP and removes from the pipeline results those that don't match using the $$PRUNE variable.
Running the following aggregate operation filter the documents more efficiently than using $where for large collections as this uses a single pipeline and native MongoDB operators, rather than JavaScript evaluations with $where, which can slow down the query:
db.T.aggregate([
{
"$redact": {
"$cond": [
{ "$gt": [ "$Grade1", "$Grade2" ] },
"$$KEEP",
"$$PRUNE"
]
}
}
])
which is a more simplified version of incorporating the two pipelines $project and $match:
db.T.aggregate([
{
"$project": {
"isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] },
"Grade1": 1,
"Grade2": 1,
"OtherFields": 1,
...
}
},
{ "$match": { "isGrade1Greater": 1 } }
])
With MongoDB 3.4 and newer:
db.T.aggregate([
{
"$addFields": {
"isGrade1Greater": { "$cmp": [ "$Grade1", "$Grade2" ] }
}
},
{ "$match": { "isGrade1Greater": 1 } }
])
While I strongly disagree with the idea of running a laravel app on shared hosting (a bad idea all around), this package would likely solve your problem. It is a package that allows you to run some artisan commands from the web. It's far from perfect, but can work for some usecases.
Another possible cause of this is trying to use the ;x509; module on something that is not X.509.
The server certificate is X.509 format, but the private key is RSA.
So:
openssl rsa -noout -text -in privkey.pem
openssl x509 -noout -text -in servercert.pem
You can get MinGW (as others have suggested) but I would recommend getting a simple IDE (not VS Express). You can try Dev C++ http://www.bloodshed.net/devcpp.html Its a simple IDE for C/C++ and uses MinGW internally. In this you can write and compile single C files without creating a full-blown "project".
Before I go on, I have the latest version (v5.0.15) of OS X Server (yes, horrible, I know...however, the web server seems to work A-OK). I searched high and low for days trying to update (or at least get Apache to point to) a new version of PHP. My mcrypt did not work, along with other extensions and I installed and reinstalled PHP countless times from http://php-osx.liip.ch/ and other tutorials until I finally noticed a tid-bit of information written in a comment in one of the many different .conf files OS X Server keeps which was that OS X Server loads it's own custom .conf file before it loads the Apache httpd.conf (located at /etc/apache2/httpd.conf). The server file is located:
/Library/Server/Web/Config/apache2/httpd_server_app.conf
When you open this file, you have to comment out this line like so:
#LoadModule php5_module libexec/apache2/libphp5.so
Then add in the correct path (which should already be installed if you have installed via the http://php-osx.liip.ch/ link):
LoadModule php5_module /usr/local/php5/libphp5.so
After this modification, my PHP finally loaded the correct PHP installation. That being said, if things go wonky, it may be because OS X is made to work off the native installation of PHP at the time of OS X installation. To revert, just undo the change above.
Anyway, hopefully this is helpful for anyone else spending countless hours on this.
Better yet, consider sp_getapplock which is designed for this. Or use SET LOCK_TIMEOUT
Otherwise, you'd have to do something with sys.dm_tran_locks which I'd use only for DBA stuff: not for user defined concurrency.
For dynamic arrays (malloc or C++ new) you need to store the size of the array as mentioned by others or perhaps build an array manager structure which handles add, remove, count, etc. Unfortunately C doesn't do this nearly as well as C++ since you basically have to build it for each different array type you are storing which is cumbersome if you have multiple types of arrays that you need to manage.
For static arrays, such as the one in your example, there is a common macro used to get the size, but it is not recommended as it does not check if the parameter is really a static array. The macro is used in real code though, e.g. in the Linux kernel headers although it may be slightly different than the one below:
#if !defined(ARRAY_SIZE)
#define ARRAY_SIZE(x) (sizeof((x)) / sizeof((x)[0]))
#endif
int main()
{
int days[] = {1,2,3,4,5};
int *ptr = days;
printf("%u\n", ARRAY_SIZE(days));
printf("%u\n", sizeof(ptr));
return 0;
}
You can google for reasons to be wary of macros like this. Be careful.
If possible, the C++ stdlib such as vector which is much safer and easier to use.
On Windows, installation of easy_install is a little bit trickier, but still quite easy. The easiest way to do it is to download the distribute_setup.py file and run it. The easiest way to run the file is to open your downloads folder and double-click on the file.
Next, add the easy_install command and other Python scripts to the command search path, by adding your Python installation’s Scripts folder to the PATH environment variable. To do that, right-click on the “Computer” icon on the Desktop or in the Start menu, and choose “Properties”. Then click on “Advanced System settings” (in Windows XP, click on the “Advanced” tab instead). Then click on the “Environment variables” button. Finally, double-click on the “Path” variable in the “System variables” section, and add the path of your Python interpreter’s Scripts folder. Be sure to delimit it from existing values with a semicolon. Assuming you are using Python 2.7 on the default path, add the following value:
;C:\Python27\Scripts And you are done! To check that it worked, open the Command Prompt and execute easy_install. If you have User Account Control enabled on Windows Vista or Windows 7, it should prompt you for administrator privileges.
Now that you have easy_install, you can use it to install pip:
easy_install pip
You can't remove keyword case. But your example can be written shorter like this:
switch ((Answer - 1) / 4)
{
case 0:
cout << "You need more cars.";
break;
case 1:
cout << "Now you need a house.";
break;
default:
cout << "What are you? A peace-loving hippie freak?";
}
Use .*, and make sure you are using your implementations' equivalent of single-line so you will match on line endings.
