To add a bit to accepted answer ...
If you get an UnfinishedStubbingException
, be sure to set the method to be stubbed after the when
closure, which is different than when you write Mockito.when
Mockito.doNothing().when(mock).method() //method is declared after 'when' closes
Mockito.when(mock.method()).thenReturn(something) //method is declared inside 'when'
As an addition to Frank Heiken's answer, if you wish to use INSERT
statements instead of copy from stdin
, then you should specify the --inserts
flag
pg_dump --host localhost --port 5432 --username postgres --format plain --verbose --file "<abstract_file_path>" --table public.tablename --inserts dbname
Notice that I left out the --ignore-version
flag, because it is deprecated.
Adding the following to my stored procedure, solved the time out error by me:

Hi I have been using this page a lot for constraints and "how to". It took me forever to get to the point of realizing I needed:
myView.translatesAutoresizingMaskIntoConstraints = NO;
to get this example to work. Thank you Userxxx, Rob M. and especially larsacus for the explanation and code here, it has been invaluable.
Here is the code in full to get the examples above to run:
UIView *myView = [[UIView alloc] init];
myView.backgroundColor = [UIColor redColor];
myView.translatesAutoresizingMaskIntoConstraints = NO; //This part hung me up
[self.view addSubview:myView];
//needed to make smaller for iPhone 4 dev here, so >=200 instead of 748
[self.view addConstraints:[NSLayoutConstraint
constraintsWithVisualFormat:@"V:|-[myView(>=200)]-|"
options:NSLayoutFormatDirectionLeadingToTrailing
metrics:nil
views:NSDictionaryOfVariableBindings(myView)]];
[self.view addConstraints:[NSLayoutConstraint
constraintsWithVisualFormat:@"H:[myView(==200)]-|"
options:NSLayoutFormatDirectionLeadingToTrailing
metrics:nil
views:NSDictionaryOfVariableBindings(myView)]];
You can call a ant task called merge on maven, to put all coverage files (*.exec) together in the same file.
If you are run unit tests use the phase prepare-package, if you run integration test so use post-integration-test.
This site has an example to how call jacoco ant task in maven project
You can use this merged file on sonar.
I had Filezilla 3.6, and had the same issue as OP. I have upgraded to 3.10.3 thinking it would fix it. Nope, still the same.
Then I did a bit digging around the options, and what worked for me is:
Edit -> Settings -> FTP -> Passive Mode and switched from "Fall back to active mode" to "Use the server's external IP address instead"
Forcing the buttons stay in the same line will make them go beyond the fixed width of the div they are in. If you are okay with that then you can make another div inside the div you already have. The new div in turn will hold the buttons and have the fixed width of however much space the two buttons need to stay in one line.
Here is an example:
<div id="parentDiv" style="width: [less-than-what-buttons-need]px;">
<div id="holdsButtons" style="width: [>=-than-buttons-need]px;">
<button id="button1">1</button>
<button id="button2">2</button>
</div>
</div>
You may want to consider overflow property for the chunk of the content outside of the parentDiv
border.
Good luck!
Use COPY command like this:
COPY foo.txt /data/foo.txt
# where foo.txt is the relative path on host
# and /data/foo.txt is the absolute path in the image
read more details for COPY in the official documentation
An alternative would be to use ADD but this is not the best practise if you dont want to use some advanced features of ADD like decompression of tar.gz files.If you still want to use ADD command, do it like this:
ADD abc.txt /data/abc.txt
# where abc.txt is the relative path on host
# and /data/abc.txt is the absolute path in the image
read more details for ADD in the official documentation
Yes. Fetch the repository and then cherry-pick from the remote branch.
Let's take an example: You want to contribute to django, so you fork its repository. In the while you work on your feature, there is much work done on the original repo by other people. So the code you forked is not the most up to date. setting a remote upstream and fetching it time to time makes sure your forked repo is in sync with the original repo.
You need to use the Spring JUnit runner in order to wire in Spring beans from your context. The code below assumes that you have a application context called testContest.xml
available on the test classpath.
import org.hibernate.SessionFactory;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;
import java.sql.SQLException;
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.startsWith;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:**/testContext.xml"})
@Transactional
public class someDaoTest {
@Autowired
protected SessionFactory sessionFactory;
@Test
public void testDBSourceIsCorrect() throws SQLException {
String databaseProductName = sessionFactory.getCurrentSession()
.connection()
.getMetaData()
.getDatabaseProductName();
assertThat("Test container is pointing at the wrong DB.", databaseProductName, startsWith("HSQL"));
}
}
Note: This works with Spring 2.5.2 and Hibernate 3.6.5
MemoryStream ms = new MemoryStream();
yourBitmap.Save(ms, ImageFormat.Bmp);
byte[] bitmapData = ms.ToArray();
Use the children
function with the :first
selector to get the single first child of element
:
element.children(":first").toggleClass("redClass");
It's worth checking task manager for any stray wscript.exe tasks that are stuck. It could be one of those that's blocking access to the file.
Visual Studio Code will work for us in debugging.
I have to call ko.applyBinding each time search button click, and filtered data is return from server, and in this case following work for me without using ko.cleanNode.
I experienced, if we replace foreach with template then it should work fine in case of collections/observableArray.
You may find this scenario useful.
<ul data-bind="template: { name: 'template', foreach: Events }"></ul>
<script id="template" type="text/html">
<li><span data-bind="text: Name"></span></li>
</script>
in Rails 3, it should be
Model.where("column = ? or other_column = ?", value, other_value)
This also includes raw sql but I dont think there is a way in ActiveRecord to do OR operation. Your question is not a noob question.
If you are using Chrome, then debug with the console. Press SHIFT+CTRL+j to get the console on screen.
Trust me, it helps a lot.
This could have been solved by using the content put inside this block {[]}
like this. Example could be referred below for better clarity.
{[
'abc',
<b>my bold</b>,
'some other text'
]}
This would preserve the formatting for text under tags while the others would be printed as plain text.
You can just cast the WebRequest to an HttpWebRequest showed below:
var request = (HttpWebRequest)WebRequest.Create(myUri);
and then instead of trying to manipulate the header list, apply it directly in the request property request.Referer:
request.Referer = "yourReferer";
These properties are available in the request object.
Your only real problem is you are passing a string, not an object with a .src
property
Some suggestions:
<button>
data-
prefixed attributes for event data on the elementMarkup:
<div id="main_img">
<img id="img" src="1772031_29_b.jpg">
</div>
<ul id="thumb_img">
<li><button data-src='1772031_29_b.jpg'><img src='1772031_29_t.jpg' /></button></li>
<li><button data-src='1772031_55_b.jpg'><img src='1772031_55_t.jpg' /></button></li>
<li><button data-src='1772031_53_b.jpg'><img src='1772031_53_t.jpg' /></button></li>
</ul>
JavaScript:
If you need to support IE and other legacy browsers, Use a proper polyfill for Array.from
function clickedButton(btn, event) {
document.getElementById('img').src = btn.getAttribute('data-src');
}
function bindClick(btn) {
btn.addEventListener('click', clickedButton.bind(null,btn));
}
// Setup click handler(s) when content is loaded
document.addEventListener("DOMContentLoaded", function(){
Array.from(document.querySelectorAll('#thumb_img > button'))
.forEach(bindClick));
});
Edit: Vanilla JS for modern browsers.
function listselect() {
var selected = [];
$('.SelectPhone').prop('checked', function () {
selected.push($(this).val());
});
alert(selected.length);
<input type="checkbox" name="SelectPhone" class="SelectPhone" value="1" />
<input type="checkbox" name="SelectPhone" class="SelectPhone" value="2" />
<input type="checkbox" name="SelectPhone" class="SelectPhone" value="3" />
<button onclick="listselect()">show count</button>
Use the below where x is the variable which holds the markup in question.
$(x).find("div").html();
I used this below if this is what you are thinking. It it worked well for me.
<?php
include $_SERVER['DOCUMENT_ROOT']."/head_lib.php";
?>
What I was trying to do was pulla file called /head_lib.php from the root folder. It would not pull anything to build the webpage. The header, footer and other key features in sub directories would never show up. Until I did above it worked like a champ.
I've found String.fromCharCode(13, 10)
helpful when using view engines.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/fromCharCode
This creates a string with the actual newline characters in it and so forces the view engine to output a newline rather than an escaped version. Eg: Using NodeJS EJS view engine - This is a simple example in which any \n should be replaced:
viewHelper.js
exports.replaceNewline = function(input) {
var newline = String.fromCharCode(13, 10);
return input.replaceAll('\\n', newline);
}
EJS
<textarea><%- viewHelper.replaceNewline("Blah\nblah\nblah") %></textarea>
Renders
<textarea>Blah
blah
blah</textarea>
replaceAll:
String.prototype.replaceAll = function (find, replace) {
var result = this;
do {
var split = result.split(find);
result = split.join(replace);
} while (split.length > 1);
return result;
};
Regex to the rescue!
import re
s = re.sub('[^0-9a-zA-Z]+', '*', s)
Example:
>>> re.sub('[^0-9a-zA-Z]+', '*', 'h^&ell`.,|o w]{+orld')
'h*ell*o*w*orld'
This was a nasty little problem, and I'd like to throw my solution in. Some other solutions I found (async.io for example) looked promising but also presented a bit of a black box. The queue / event loop approach sort of ties you to a certain implementation. The concurrent futures source code, however, is around only 1000 lines, and easy to comprehend. It allowed me to easily solve my problem: create ad-hoc worker threads without much setup, and to be able to catch exceptions in the main thread.
My solution uses the concurrent futures API and threading API. It allows you to create a worker which gives you both the thread and the future. That way, you can join the thread to wait for the result:
worker = Worker(test)
thread = worker.start()
thread.join()
print(worker.future.result())
...or you can let the worker just send a callback when done:
worker = Worker(test)
thread = worker.start(lambda x: print('callback', x))
...or you can loop until the event completes:
worker = Worker(test)
thread = worker.start()
while True:
print("waiting")
if worker.future.done():
exc = worker.future.exception()
print('exception?', exc)
result = worker.future.result()
print('result', result)
break
time.sleep(0.25)
Here's the code:
from concurrent.futures import Future
import threading
import time
class Worker(object):
def __init__(self, fn, args=()):
self.future = Future()
self._fn = fn
self._args = args
def start(self, cb=None):
self._cb = cb
self.future.set_running_or_notify_cancel()
thread = threading.Thread(target=self.run, args=())
thread.daemon = True #this will continue thread execution after the main thread runs out of code - you can still ctrl + c or kill the process
thread.start()
return thread
def run(self):
try:
self.future.set_result(self._fn(*self._args))
except BaseException as e:
self.future.set_exception(e)
if(self._cb):
self._cb(self.future.result())
...and the test function:
def test(*args):
print('args are', args)
time.sleep(2)
raise Exception('foo')
If you are running against IIS rather than the VS webdev server, ensure that Index.aspx is one of your default files and that directory browsing is turned off.
There is unlikely to be any performance difference between the two operations in your usage. There is no type-conversion to be done because both parameters are already the same type. Both operations will have a type comparison followed by a value comparison.
Slight improvement on @arun-p-johny answer:
In html,
<pre id="log"></pre>
In js,
(function () {
var old = console.log;
var logger = document.getElementById('log');
console.log = function () {
for (var i = 0; i < arguments.length; i++) {
if (typeof arguments[i] == 'object') {
logger.innerHTML += (JSON && JSON.stringify ? JSON.stringify(arguments[i], undefined, 2) : arguments[i]) + '<br />';
} else {
logger.innerHTML += arguments[i] + '<br />';
}
}
}
})();
Start using:
console.log('How', true, new Date());
Please make sure you have typed correct spelling of using script section in view
the correct is
@section scripts{ //your script here}
if you typed @section script{ //your script here}
this is wrong.
When looking for the existence of a element in an array, proper casting is required to pass the SQL parser of postgres. Here is one example query using array contains operator in the join clause:
For simplicity I only list the relevant part:
table1 other_name text[]; -- is an array of text
The join part of SQL shown
from table1 t1 join table2 t2 on t1.other_name::text[] @> ARRAY[t2.panel::text]
The following also works
on t2.panel = ANY(t1.other_name)
I am just guessing that the extra casting is required because the parse does not have to fetch the table definition to figure the exact type of the column. Others please comment on this.
this did it for me. you can vary the options for the output format to Base64.Default whatsoever.
// encode base64 from image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
imageBitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
encodedString = Base64.encodeToString(b, Base64.URL_SAFE | Base64.NO_WRAP);
One solution (though not very pretty) is to use Apache common List/Set mutation
import org.apache.commons.collections.list.SetUniqueList;
final List<Long> vertexes=SetUniqueList.setUniqueList(new LinkedList<>());
it is a list without duplicates
Take note of the checked
and unchecked
keywords.
It matters if you want the result truncated to the int or an exception raised if the result doesnt fit in signed 32 bits. The default is unchecked.
now 2020, i am face to same question, but for this old question, there are so many new answer, just list some of it:
plugins: [
new HtmlWebpackPlugin({
// 1. title is the parameter, you can use in ejs template
templateParameters:{
title: JSON.stringify(someting: 'something'),
},
}),
//2. BUILT_AT is a parameter too. can use it.
new webpack.DefinePlugin({
BUILT_AT: webpack.DefinePlugin.runtimeValue(Date.now,"some"),
}),
//3. for webpack5, you can use global variable: __webpack_hash__
//new webpack.ExtendedAPIPlugin()
],
//4. this is not variable, this is module, so use 'import tt' to use it.
externals: {
'ex_title': JSON.stringify({
tt: 'eitentitle',
})
},
the 4 ways only basic, there are even more ways that i believe. but i think maybe this 4ways is the most simple.
Generally this error arise when we send header after echoing or printing. If this error arise on a specific page then make sure that page is not echoing anything before calling to start_session()
.
Example of Unpredictable Error:
<?php //a white-space before <?php also send for output and arise error
session_start();
session_regenerate_id();
//your page content
One more example:
<?php
includes 'functions.php';
?> <!-- This new line will also arise error -->
<?php
session_start();
session_regenerate_id();
//your page content
Conclusion: Do not output any character before calling session_start()
or header()
functions not even a white-space or new-line
Maybe this is obvious, maybe not, but you can make the string '\' by calling x=chr(92)
x=chr(92)
print type(x), len(x) # <type 'str'> 1
y='\\'
print type(y), len(y) # <type 'str'> 1
x==y # True
x is y # False
Detect key press, including key combinations:
window.addEventListener('keydown', function (e) {
if (e.ctrlKey && e.keyCode == 90) {
// Ctrl + z pressed
}
});
Benefit here is that you are not overwriting any global properties, but instead merely introducing a side effect. Not good, but definitely a whole lot less nefarious than other suggestions on here.
In my case it turned out to be a problem with the installation of my certificate on the service I was trying to consume with cURL. I failed to bundle/concatenate the intermediate and root certificates into my domain certificate. It wasn't obvious at first that this was the problem because Chrome worked it out and accepted the certificate in spite of leaving out the intermediate and root certificates.
After bundling the certificate, everything worked as expected. I bundled like this
$ cat intermediate.crt >> domain.crt
And repeated for all intermediate and the root certificate.

First, I realize I am late in answering this question.
Before discussing synchronous and asynchronous, let us briefly look at how programs run.
In the synchronous case, each statement completes before the next statement is run. In this case the program is evaluated exactly in order of the statements.
This is how asynchronous works in JavaScript. There are two parts in the JavaScript engine, one part that looks at the code and enqueues operations and another that processes the queue. The queue processing happens in one thread, that is why only one operation can happen at a time.
When an asynchronous operation (like the second database query) is seen, the code is parsed and the operation is put in the queue, but in this case a callback is registered to be run when this operation completes. The queue may have many operations in it already. The operation at the front of the queue is processed and removed from the queue. Once the operation for the database query is processed, the request is sent to the database and when complete the callback will be executed on completion. At this time, the queue processor having "handled" the operation moves on the next operation - in this case
console.log("Hello World");
The database query is still being processed, but the console.log operation is at the front of the queue and gets processed. This being a synchronous operation gets executed right away resulting immediately in the output "Hello World". Some time later, the database operation completes, only then the callback registered with the query is called and processed, setting the value of the variable result to rows.
It is possible that one asynchronous operation will result in another asynchronous operation, this second operation will be put in the queue and when it comes to the front of the queue it will be processed. Calling the callback registered with an asynchronous operation is how JavaScript run time returns the outcome of the operation when it is done.
A simple method of knowing which JavaScript operation is asynchronous is to note if it requires a callback - the callback is the code that will get executed when the first operation is complete. In the two examples in the question, we can see only the second case has a callback, so it is the asynchronous operation of the two. It is not always the case because of the different styles of handling the outcome of an asynchronous operation.
To learn more, read about promises. Promises are another way in which the outcome of an asynchronous operation can be handled. The nice thing about promises is that the coding style feels more like synchronous code.
Many libraries like node 'fs', provide both synchronous and asynchronous styles for some operations. In cases where the operation does not take long and is not used a lot - as in the case of reading a config file - the synchronous style operation will result in code that is easier to read.
The difference between <pluginManagement/>
and <plugins/>
is that a <plugin/>
under:
<pluginManagement/>
defines the settings for plugins that will be inherited by modules in your build. This is great for cases where you have a parent pom file.
<plugins/>
is a section for the actual invocation of the plugins. It may or may not be inherited from a <pluginManagement/>
.
You don't need to have a <pluginManagement/>
in your project, if it's not a parent POM. However, if it's a parent pom, then in the child's pom, you need to have a declaration like:
<plugins>
<plugin>
<groupId>com.foo</groupId>
<artifactId>bar-plugin</artifactId>
</plugin>
</plugins>
Notice how you aren't defining any configuration. You can inherit it from the parent, unless you need to further adjust your invocation as per the child project's needs.
For more specific information, you can check:
The Maven pom.xml reference: Plugins
The Maven pom.xml reference: Plugin Management
I found myself in a similar predicament today while trying to run a command through a Node.js module:
I was using the PowerShell and trying to run:
command -e 'func($a)'
But with the extra symbols, PowerShell was mangling the arguments. To fix, I back-tick escaped double-quote marks:
command -e `"func($a)`"
When using the MVVM Command pattern for Button function (recommended practice), a simple way to trigger the effect of the Button is as follows:
someButton.Command.Execute(someButton.CommandParameter);
This will use the Command object which the button triggers and pass the CommandParameter defined by the XAML.

What happens when the repository owner has not prepared a zip file, and you just want a download to use yourself? There is an answer and you don't need to go though that horrid process to download software, install and register keys and whatnot on GitHub, etc.!
To simply download a repository as a zip file: add the extra path '/zipball/master/' to the end of the repository URL and voila, it gives you a zip file of the whole lot.
For example,
becomes:
It then gives you a zip file to download.

If you're using .NET 4.5 and want to use async then you can use HttpClient

}
I encountered difficulties with Roi-Kyi Bryant's solution when multiple add-ins tried to modify the ribbon. I also don't have admin access on my work-computer, which ruled out installing the Custom UI Editor

module for Chart Tools.xlam
looks like
Option Explicit
Public Sub MoveChartWithRelativeLinksCallBack(ByRef control As IRibbonControl)
MoveChartWithRelativeLinks
End Sub
Public Sub MoveChartToManySheetsWithRelativeLinksCallBack(ByRef control As IRibbonControl)
MoveChartToManySheetsWithRelativeLinks
End Sub
Public Sub DeleteAllChartsInWorkbookSharingAnAddressCallBack(ByRef control As IRibbonControl)
DeleteAllChartsInWorkbookSharingAnAddress
End Sub
My CallBacks
module for Priveleged UDFs.xlam
looks like
Option Explicit
Public Sub InitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
ThisWorkbook.InitialisePrivelegedUDFs
End Sub
Public Sub DeInitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
ThisWorkbook.DeInitialisePrivelegedUDFs
End Sub
Different elements have a different callback sub-routine signature. For buttons, the required sub-routine parameter is ByRef control As IRibbonControl
. If you don't conform to the required callback signature, you will receive an error while compiling your VBA project/projects. Part 3 of the Microsoft guide defines all the callback signatures.
Here's what my finished example looks like
Some closing tips
idQ
and xlmns:
keyword. In my example, the Chart Tools.xlam
and Priveleged UDFs.xlam
both have access to the elements with idQ
's equal to x:chartToolsTab
and x:privelgedUDFsTab
. For this to work, the x:
is required, and, I've defined its namespace in the first line of my customUI.xml
file, <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.isMSO

Try this :
import urllib, urllib2, json
url = 'http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1'
request = urllib2.Request(url)
request.add_header('User-Agent','Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)')
request.add_header('Content-Type','application/json')
response = urllib2.urlopen(request)
json_object = json.load(response)
#print json_object['results']
if json_object['team'] == []:
print 'No Data!'
else:
for rows in json_object['team']:
print 'Team ID:' + rows['team_id']
print 'Team Name:' + rows['team_name']
print 'Team URL:' + rows['team_icon_url']
I would be inclined to include the year in the output. One way:
select to_char(DATE_CREATED, 'YYYY-MM'), sum(Num_of_Pictures)
from pictures_table
group by to_char(DATE_CREATED, 'YYYY-MM')
order by 1
Another way (more standard SQL):
select extract(year from date_created) as yr, extract(month from date_created) as mon,
sum(Num_of_Pictures)
from pictures_table
group by extract(year from date_created), extract(month from date_created)
order by yr, mon;
Remember the order by, since you presumably want these in order, and there is no guarantee about the order that rows are returned in after a group by.
there is a nicer alternative - use query() method:
In [58]: df = pd.DataFrame({'closing_price': np.random.randint(95, 105, 10)})
In [59]: df
Out[59]:
closing_price
0 104
1 99
2 98
3 95
4 103
5 101
6 101
7 99
8 95
9 96
In [60]: df.query('99 <= closing_price <= 101')
Out[60]:
closing_price
1 99
5 101
6 101
7 99
UPDATE: answering the comment:
I like the syntax here but fell down when trying to combine with expresison;
df.query('(mean + 2 *sd) <= closing_price <=(mean + 2 *sd)')
In [161]: qry = "(closing_price.mean() - 2*closing_price.std())" +\
...: " <= closing_price <= " + \
...: "(closing_price.mean() + 2*closing_price.std())"
...:
In [162]: df.query(qry)
Out[162]:
closing_price

Using pandas dataframe,we can write to csv. First create a dataframe as per the your needs for storing in csv. Then create csv of the dataframe using pd.DataFrame.to_csv() API.
using jQuery UI you can use the dialog that offers. More information at http://docs.jquery.com/UI/Dialog
I think you are confused about how the compiler puts things together. When you use -c
flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o
files thus don't mix with -c
, and compiler warns you about that. Symbols from object file are not moved to other object files like that.
All object files should be on the final linker invocation, which is not the case here, so linker (called via g++
front-end) complains about missing symbols.
Here's a small example (calling g++
explicitly for clarity):
PROG ?= myprog
OBJS = worker.o main.o
all: $(PROG)
.cpp.o:
g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<
$(PROG): $(OBJS)
g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)
There's also makedepend
utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M
gcc
option for building make
rules.
This answer only really works if you don't need to do anything other than transferring the inner code (innerHTML) from one to the other:
// Define old parent
var oldParent = document.getElementById('old-parent');
// Define new parent
var newParent = document.getElementById('new-parent');
// Basically takes the inner code of the old, and places it into the new one
newParent.innerHTML = oldParent.innerHTML;
// Delete / Clear the innerHTML / code of the old Parent
oldParent.innerHTML = '';
Hope this helps!
The easiest way to do this is to write file.readline()[0:-1]
This will read everything except the last character, which is the newline.
1) What is Express.js?
Express.js is a Node.js framework. It's the most popular framework as of now (the most starred on NPM).
.
It's built around configuration and granular simplicity of Connect middleware. Some people compare Express.js to Ruby Sinatra vs. the bulky and opinionated Ruby on Rails.
2) What is the purpose of it with Node.js?
That you don't have to repeat same code over and over again. Node.js is a low-level I/O mechanism which has an HTTP module. If you just use an HTTP module, a lot of work like parsing the payload, cookies, storing sessions (in memory or in Redis), selecting the right route pattern based on regular expressions will have to be re-implemented. With Express.js, it is just there for you to use.
3) Why do we actually need Express.js? How it is useful for us to use with Node.js?
The first answer should answer your question. If no, then try to write a small REST API server in plain Node.js (that is, using only core modules) and then in Express.js. The latter will take you 5-10x less time and lines of code.
What is Redis? Does it come with Express.js?
Redis is a fast persistent key-value storage. You can optionally use it for storing sessions with Express.js, but you don't need to. By default, Express.js has memory storage for sessions. Redis also can be use for queueing jobs, for example, email jobs.
Check out my tutorial on REST API server with Express.js.
MVC but not by itself
Express.js is not an model-view-controller framework by itself. You need to bring your own object-relational mapping libraries such as Mongoose for MongoDB, Sequelize (http://sequelizejs.com) for SQL databases, Waterline (https://github.com/balderdashy/waterline) for many databases into the stack.
Alternatives
Other Node.js frameworks to consider (https://www.quora.com/Node-js/Which-Node-js-framework-is-best-for-building-a-RESTful-API):
UPDATE: I put together this resource that aid people in choosing Node.js frameworks: http://nodeframework.com
UPDATE2: We added some GitHub stats to nodeframework.com so now you can compare the level of social proof (GitHub stars) for 30+ frameworks on one page.
Full-stack:

Static site generators:
text-align: center will only work for horizontal centering. For it to be in the complete center, vertical and horizontal you can do the following :
div
{
position: relative;
}
div img
{
position: absolute;
top: 50%;
left: 50%;
margin-left: [-50% of your image's width];
margin-top: [-50% of your image's height];
}
The other solution are OK, but there is no need to add separator at the very last if using :after or at the very beginning if using :before.
SO:
case :after
.link:after {
content: '|';
padding: 0 1rem;
}
.link:last-child:after {
content: '';
}
case :before
.link:before {
content: '|';
padding: 0 1rem;
}
.link:first-child:before {
content: '';
}
a simple code snippet that i prepared, hope it will be usefull for you;
$ages = array("Kerem"=>"35","Ahmet"=>"65","Talip"=>"62","Kamil"=>"60");
reset($ages);
for ($i=0; $i < count($ages); $i++){
echo "Key : " . key($ages) . " Value : " . current($ages) . "<br>";
next($ages);
}
reset($ages);
It work for me at code first. It return a list with matching property of view model(StudentChapterCompletionViewModel)
var studentIdParameter = new SqlParameter
{
ParameterName = "studentId",
Direction = ParameterDirection.Input,
SqlDbType = SqlDbType.BigInt,
Value = studentId
};
var results = Context.Database.SqlQuery<StudentChapterCompletionViewModel>(
"exec dbo.sp_StudentComplettion @studentId",
studentIdParameter
).ToList();
Updated for Context
Context is the instance of the class that Inherit DbContext like below.
public class ApplicationDbContext : DbContext
{
public DbSet<City> City { get; set; }
}
var Context = new ApplicationDbContext();
Or you can split your string to string array, splitting by space and then add every item of string array to empty string.
May be this is not the best and fastest method, but you can try, if other answer aren't what you whant.
If you want object key to be same as variable name, there's a short hand in ES 2015. New notations in ECMAScript 2015
var thetop = 10;
var obj = { thetop };
console.log(obj.thetop); // print 10
You can do it without setlocal
, because of the setlocal
command the variable won't survive an endlocal
because it was created in setlocal
. In this way the variable will be defined the right way.
To do that use this code:
set var1=A
set var2=B
set AB=hi
call set newvar=%%%var1%%var2%%%
echo %newvar%
Note: You MUST use call
before you set the variable or it won't work.
heikkim is right, here is some sample code adapted from some code I have:
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Row;
...
for (int rowIndex = 0; rowIndex <= sheet.getLastRowNum(); rowIndex++) {
row = sheet.getRow(rowIndex);
if (row != null) {
Cell cell = row.getCell(colIndex);
if (cell != null) {
// Found column and there is value in the cell.
cellValueMaybeNull = cell.getStringCellValue();
// Do something with the cellValueMaybeNull here ...
// break; ???
}
}
}
For the colCount
use something like row.getPhysicalNumberOfCells()
If you want the number of rows to be flexible, you can add row_number
in the SQL. For SQL server:
SELECT ROW_NUMBER() OVER (ORDER BY myOrder) ROW_NUMBER, * FROM myTable
Then filter the datatable on row_number:
Dataview dv= new Dataview(dt, "ROW_NUMBER<=100", "", CurrentRows)
You can use index arrays, simply pass your ind_pos
as an index argument as below:
a = np.array([0,88,26,3,48,85,65,16,97,83,91])
ind_pos = np.array([1,5,7])
print(a[ind_pos])
# [88,85,16]
Index arrays do not necessarily have to be numpy arrays, they can be also be lists or any sequence-like object (though not tuples).
Ctrl+/ to toggle "//" comments and Ctrl+Shift/ to toggle "/* */" comments. At least for Java, anyway - other tooling may have different shortcuts.
Ctrl+\ will remove a block of either comment, but won't add comments.
EDIT: It's Ctrl on a PC, but on a Mac the shortcuts may all be Cmd instead. I don't have a Mac myself, so can't easily check
Other answers have demonstrated the way you should do this. Here's a way you shouldn't:
>>> def foo(counter=[0]):
... counter[0] += 1
... print("Counter is %i." % counter[0]);
...
>>> foo()
Counter is 1.
>>> foo()
Counter is 2.
>>>
Default values are initialized only when the function is first evaluated, not each time it is executed, so you can use a list or any other mutable object to store static values.
Try both pip install pywin32
and pip install pypiwin32

decimal = int(hex, 16);
print(hex,"in Decimal =",decimal);
print(hex,"in octal =",oct(decimal));
print(hex,"in Binary =",bin(decimal));

Docker originally used LinuX Containers (LXC), but later switched to runC (formerly known as libcontainer), which runs in the same operating system as its host. This allows it to share a lot of the host operating system resources. Also, it uses a layered filesystem (AuFS) and manages networking.
AuFS is a layered file system, so you can have a read only part and a write part which are merged together. One could have the common parts of the operating system as read only (and shared amongst all of your containers) and then give each container its own mount for writing.
So, let's say you have a 1 GB container image; if you wanted to use a full VM, you would need to have 1 GB x number of VMs you want. With Docker and AuFS you can share the bulk of the 1 GB between all the containers and if you have 1000 containers you still might only have a little over 1 GB of space for the containers OS (assuming they are all running the same OS image).
A full virtualized system gets its own set of resources allocated to it, and does minimal sharing. You get more isolation, but it is much heavier (requires more resources). With Docker you get less isolation, but the containers are lightweight (require fewer resources). So you could easily run thousands of containers on a host, and it won't even blink. Try doing that with Xen, and unless you have a really big host, I don't think it is possible.
A full virtualized system usually takes minutes to start, whereas Docker/LXC/runC containers take seconds, and often even less than a second.
There are pros and cons for each type of virtualized system. If you want full isolation with guaranteed resources, a full VM is the way to go. If you just want to isolate processes from each other and want to run a ton of them on a reasonably sized host, then Docker/LXC/runC seems to be the way to go.
For more information, check out this set of blog posts which do a good job of explaining how LXC works.
Why is deploying software to a docker image (if that's the right term) easier than simply deploying to a consistent production environment?
Deploying a consistent production environment is easier said than done. Even if you use tools like Chef and Puppet, there are always OS updates and other things that change between hosts and environments.
Docker gives you the ability to snapshot the OS into a shared image, and makes it easy to deploy on other Docker hosts. Locally, dev, qa, prod, etc.: all the same image. Sure you can do this with other tools, but not nearly as easily or fast.
This is great for testing; let's say you have thousands of tests that need to connect to a database, and each test needs a pristine copy of the database and will make changes to the data. The classic approach to this is to reset the database after every test either with custom code or with tools like Flyway - this can be very time-consuming and means that tests must be run serially. However, with Docker you could create an image of your database and run up one instance per test, and then run all the tests in parallel since you know they will all be running against the same snapshot of the database. Since the tests are running in parallel and in Docker containers they could run all on the same box at the same time and should finish much faster. Try doing that with a full VM.
From comments...
Interesting! I suppose I'm still confused by the notion of "snapshot[ting] the OS". How does one do that without, well, making an image of the OS?
Well, let's see if I can explain. You start with a base image, and then make your changes, and commit those changes using docker, and it creates an image. This image contains only the differences from the base. When you want to run your image, you also need the base, and it layers your image on top of the base using a layered file system: as mentioned above, Docker uses AuFS. AuFS merges the different layers together and you get what you want; you just need to run it. You can keep adding more and more images (layers) and it will continue to only save the diffs. Since Docker typically builds on top of ready-made images from a registry, you rarely have to "snapshot" the whole OS yourself.
You could do it like this:
iterations = 10
variables = 2
output <- matrix(ncol=variables, nrow=iterations)
for(i in 1:iterations){
output[i,] <- runif(2)
}
output
and then turn it into a data.frame
output <- data.frame(output)
class(output)
what this does:
Dummy data (you should supply this for us)
visual1 = data.frame(ISSUE_DATE=runif(100,2006,2008),COUNTED=runif(100,0,50))
visual2 = data.frame(ISSUE_DATE=runif(100,2006,2008),COUNTED=runif(100,0,50))
combine:
visuals = rbind(visual1,visual2)
visuals$vis=c(rep("visual1",100),rep("visual2",100)) # 100 points of each flavour
Now do:
ggplot(visuals, aes(ISSUE_DATE,COUNTED,group=vis,col=vis)) +
geom_point() + geom_smooth()
and adjust colours etc to taste.
It took me a hell of a long time to really get a handle on this. The key to me was in understanding that "@" is for stuff that you want evaluated in situ and passed through into the directive as a constant where "=" actually passes the object itself.
There's a nice blog post that explains this this at: http://blog.ramses.io/technical/AngularJS-the-difference-between-@-&-and-=-when-declaring-directives-using-isolate-scopes
use the request()
helper instead. You don't have to worry about use
statements and thus this sort of problem wont happen again.
$input = request()->all();
simple
It should respond to ActionListeners, like this:
combo.addActionListener (new ActionListener () {
public void actionPerformed(ActionEvent e) {
doSomething();
}
});
@John Calsbeek rightly points out that addItemListener()
will work, too. You may get 2 ItemEvents
, though, one for the deselection of the previously selected item, and another for the selection of the new item. Just don't use both event types!
One of the best approach if you do not want to return any columns from table2
is to use the NOT EXISTS
SELECT table1.id
FROM table1 T1
WHERE
NOT EXISTS (SELECT *
FROM table2 T2
WHERE T1.id = T2.user_one
OR T1.id = T2.user_two)
Semantically this says what you want to query: Select every row where there is no matching record in the second table.
MySQL is optimized for EXISTS
: It returns as soon as it finds the first matching record.
The sample above worked like a charm. I just did a modification just in case I need to manage multiple values. I hope this helps!
app.service('sharedProperties', function () {
var hashtable = {};
return {
setValue: function (key, value) {
hashtable[key] = value;
},
getValue: function (key) {
return hashtable[key];
}
}
});
At launch, Java
was the only officially supported programming language for building distributable third-party Android software.
Android Native Development Kit (Android NDK) which will allow developers to build Android software components with C
and C++
.
In addition to delivering support for native code, Google is also extending Android to support popular dynamic scripting languages. Earlier this month, Google launched the Android Scripting Environment (ASE) which allows third-party developers to build simple Android applications with perl
, JRuby
, Python
, LUA
and BeanShell
. For having idea and usage of ASE, refer this Example link.
Scala is also supported. For having examples of Scala, refer these Example link-1 , Example link-2 , Example link-3 .
Just now i have referred one Article Here in which i found some useful information as follows:
(C# .net - Mono, etc)
.LUA
, Perl
, Python
, BeanShell
, etc.
I have read 2nd article at Google Releases 'Simple' Android Programming Language . For example of this, refer this .
Just now (2 Aug 2010) i have read an article which describes regarding "Frink Programming language and Calculating Tool for Android", refer this links Link-1 , Link-2
On 4-Aug-2010, i have found Regarding RenderScript
. Basically, It is said to be a C-like language for high performance graphics programming, which helps you easily write efficient Visual effects and animations in your Android Applications. Its not released yet as it isn't finished.
Indeed SET TEST_VARIABLE=value works for current process only, so SETX
is required. A quick example for permanently storing an environment variable at user level.
SETX TEST_VARIABLE etc
. Not applied yet (echo %TEST_VARIABLE%

,echo %TEST_VARIABLE%
shows etc
.etc
.Since I can not add a comment to the marked answer I will just post this here.
In addition to the correct answer you can indeed have this validated. Since this meta tag is only directed for IE all you need to do is add a IE conditional.
<!--[if IE]>
<meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">
<![endif]-->
Doing this is just like adding any other IE conditional statement and only works for IE and no other browsers will be affected.
I had exactly the same problem as you, tried everything, but the solution is really easy:
I would look at the Join operator:
from r in list join i in listofIds on r.Id equals i select r
I'm not sure how this would be optimized over the Contains methods, but at least it gives the compiler a better idea of what you're trying to do. It's also sematically closer to what you're trying to achieve.
Edit: Extension method syntax for completeness (now that I've figured it out):
var results = listofIds.Join(list, i => i, r => r.Id, (i, r) => r);
public static void ClearLine(int lines = 1)
{
for (int i = 1; i <= lines; i++)
{
Console.SetCursorPosition(0, Console.CursorTop - 1);
Console.Write(new string(' ', Console.WindowWidth));
Console.SetCursorPosition(0, Console.CursorTop - 1);
}
}
You could use an onclick
event handler in order to get the input value for the text field. Make sure you give the field an unique id
attribute so you can refer to it safely through document.getElementById()
:
If you want to dynamically add elements, you should have a container where to place them. For instance, a <div id="container">
. Create new elements by means of document.createElement()
, and use appendChild()
to append each of them to the container. You might be interested in outputting a meaningful name
attribute (e.g. name="member"+i
for each of the dynamically generated <input>
s if they are to be submitted in a form.
Notice you could also create <br/>
elements with document.createElement('br')
. If you want to just output some text, you can use document.createTextNode()
instead.
Also, if you want to clear the container every time it is about to be populated, you could use hasChildNodes()
and removeChild()
together.
<html>
<head>
<script type='text/javascript'>
function addFields(){
// Number of inputs to create
var number = document.getElementById("member").value;
// Container <div> where dynamic content will be placed
var container = document.getElementById("container");
// Clear previous contents of the container
while (container.hasChildNodes()) {
container.removeChild(container.lastChild);
}
for (i=0;i<number;i++){
// Append a node with a random text
container.appendChild(document.createTextNode("Member " + (i+1)));
// Create an <input> element, set its type and name attributes
var input = document.createElement("input");
input.type = "text";
input.name = "member" + i;
container.appendChild(input);
// Append a line break
container.appendChild(document.createElement("br"));
}
}
</script>
</head>
<body>
<input type="text" id="member" name="member" value="">Number of members: (max. 10)<br />
<a href="#" id="filldetails" onclick="addFields()">Fill Details</a>
<div id="container"/>
</body>
</html>

See a working sample in this JSFiddle.
Add the 'columns' parameter:
frame = pd.DataFrame({
'one thing':[1,2,3,4],
'second thing':[0.1,0.2,1,2],
'other thing':['a','e','i','o']},
columns=['one thing', 'second thing', 'other thing']
)
Use the -printcert
command like this:
keytool -printcert -file certificate.pem
You shouldn't send a request body with an HTTP GET request. You should modify addDepartment()
so that it only supports POST, and POST your JSON to that endpoint. If you want to GET information about a department, you should create a separate controller method that does that (and does not require a request body).
Also, double-check your endpoint definitions since you have misspelled "reimbursement" in the $.ajax
call.
for set empty all input such textarea select and input run this code:
$('#message').val('').change();
another approach is to use the double colons:
mtcars %>%
dplyr::group_by(cyl, gear) %>%
dplyr::summarise(length(gear))
This isn't directly answering the question, but to me, it looks like you might want the functionality of collections.Counter.
from collections import Counter
to_count = ["foo", "foo", "bar", "baz", "foo", "bar"]
count = Counter(to_count)
print(count)
print("acts just like the desired dictionary:")
print("bar occurs {} times".format(count["bar"]))
print("any item that does not occur in the list is set to 0:")
print("dog occurs {} times".format(count["dog"]))
print("can iterate over items from most frequent to least:")
for item, times in count.most_common():
print("{} occurs {} times".format(item, times))
This results in the output
Counter({'foo': 3, 'bar': 2, 'baz': 1})
acts just like the desired dictionary:
bar occurs 2 times
any item that does not occur in the list is set to 0:
dog occurs 0 times
can iterate over items from most frequent to least:
foo occurs 3 times
bar occurs 2 times
baz occurs 1 times
You can do the entire conversion in one line, using the following code:
String number = "1000500000.574";
String convertedString = new DecimalFormat("#,###.##").format(Double.parseDouble(number));
The last two # signs in the DecimalFormat constructor can also be 0s. Either way works.
The good news is a transaction in SQL Server can span multiple batches (each exec
is treated as a separate batch.)
You can wrap your EXEC
statements in a BEGIN TRANSACTION
and COMMIT
but you'll need to go a step further and rollback if any errors occur.
Ideally you'd want something like this:
BEGIN TRY
BEGIN TRANSACTION
exec( @sqlHeader)
exec(@sqlTotals)
exec(@sqlLine)
COMMIT
END TRY
BEGIN CATCH
IF @@TRANCOUNT > 0
ROLLBACK
END CATCH
The BEGIN TRANSACTION
and COMMIT
I believe you are already familiar with. The BEGIN TRY
and BEGIN CATCH
blocks are basically there to catch and handle any errors that occur. If any of your EXEC
statements raise an error, the code execution will jump to the CATCH
block.
Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.
I would recommend checking the connections to show the maximum thread connection is
show variables like "max_connections";
sample
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| max_connections | 13 |
+-----------------+-------+
1 row in set
Then increase it by example
set global max_connections = 500;
Instead you can use before insert and get max pkid for the particular table and then update the maximium pkid table record.
A good explanation from http://www.sqlines.com/postgresql/datatypes/text:
The only difference between TEXT and VARCHAR(n) is that you can limit the maximum length of a VARCHAR column, for example, VARCHAR(255) does not allow inserting a string more than 255 characters long.
Both TEXT and VARCHAR have the upper limit at 1 Gb, and there is no performance difference among them (according to the PostgreSQL documentation).
You can try anchoring it to the end of the string, something like \\[^\\]*$
. Though I'm not sure if one absolutely has to use regexp for the task.
An alternative is to use String.format
:
double[] arr = { 23.59004,
35.7,
3.0,
9
};
for ( double dub : arr ) {
System.out.println( String.format( "%.2f", dub ) );
}
output:
23.59
35.70
3.00
9.00
You could also use System.out.format
(same method signature), or create a java.util.Formatter
which works in the same way.
For Python 3.x, use input()
. For Python 2.x, use raw_input()
. Don't forget you can add a prompt string in your input()
call to create one less print statement. input("GUESS THAT NUMBER!")
.
Edit: I recommend you DO NOT run ADB under VirtualBox if you are using a Windows Host. Somehow I got VirtualBox to lock the device drivers on the host, eventually making it so that the ADB wouldn't work on the client nor the host for any device I plugged in. To fix, I removed VirtualBox extensions on the host and ran http://www.nirsoft.net/utils/usb_devices_view.html to delete the incorrect drivers. I could not get the correct drivers to load while VirtualBox extensions were installed, and this problem was a complete bastard to diagnose and fix.
Edit 2: Also the following is probably out of date, now that Google have released an integrated ADB extension for Chrome.
What an installation nightmare... Here are the steps I needed to get my Nexus 10 recognised on an XP virtual machine running under VirtualBox:
adb devices
finally shows me the device...You should have a default server for catch-all, you can return 404
or better to not respond at all (will save some bandwidth) by returning 444
which is nginx specific HTTP response that simply close the connection and return nothing
server {
listen 80 default_server;
server_name _; # some invalid name that won't match anything
return 444;
}
export
in sh
and related shells (such as bash
), marks an environment variable to be exported to child-processes, so that the child inherits them.
The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the environment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to word.
This works fine

Box-Muller implementation:
#include <cstdlib>
#include <cmath>
#include <ctime>
#include <iostream>
using namespace std;
// return a uniformly distributed random number
double RandomGenerator()
{
return ( (double)(rand()) + 1. )/( (double)(RAND_MAX) + 1. );
}
// return a normally distributed random number
double normalRandom()
{
double y1=RandomGenerator();
double y2=RandomGenerator();
return cos(2*3.14*y2)*sqrt(-2.*log(y1));
}
int main(){
double sigma = 82.;
double Mi = 40.;
for(int i=0;i<100;i++){
double x = normalRandom()*sigma+Mi;
cout << " x = " << x << endl;
}
return 0;
}
These functions should work.
// First, cache your array dimensions so you don't have to
// access them during each iteration of your for loops.
int rowLength = array.length, // array width (# of columns)
colLength = array[0].length; // array height (# of rows)
// This is your function:
// Prints array elements row by row
var rowString = "";
for(int x = 0; x < rowLength; x++){ // x is the column's index
for(int y = 0; y < colLength; y++){ // y is the row's index
rowString += array[x][y];
} System.out.println(rowString)
}
// This is the one you want:
// Prints array elements column by column
var colString = "";
for(int y = 0; y < colLength; y++){ // y is the row's index
for(int x = 0; x < rowLength; x++){ // x is the column's index
colString += array[x][y];
} System.out.println(colString)
}
In the first block, the inner loop iterates over each item in the row before moving to the next column.
In the second block (the one you want), the inner loop iterates over all the columns before moving to the next row.
tl;dr:
Essentially, the for()
loops in both functions are switched. That's it.
I hope this helps you to understand the logic behind iterating over 2-dimensional arrays.
Also, this works whether you have a string[,] or string[][]
Adding my piece of experience. I spent hours trying to find why I had CORS error.
It happens that I've renamed my cloud function (the very first I was trying after a big upgrade).
So when my firebase app was calling the cloud function with an incorrect name, it should have thrown a 404 error, not a CORS error.
Fixing the cloud function name in my firebase app fixed the issue.
I've filled a bug report about this here https://firebase.google.com/support/troubleshooter/report/bugs
Another C# example. I just made an extension method for it.
public static string GetCellFromTable(this IWebElement table, int rowIndex, int columnIndex)
{
return table.FindElements(By.XPath("./tbody/tr"))[rowIndex].FindElements(By.XPath("./td"))[columnIndex].Text;
}
I wrote a method for this sometime back. It deletes the specified directory and returns true if the directory deletion was successful.
/**
* Delets a dir recursively deleting anything inside it.
* @param dir The dir to delete
* @return true if the dir was successfully deleted
*/
public static boolean deleteDirectory(File dir) {
if(! dir.exists() || !dir.isDirectory()) {
return false;
}
String[] files = dir.list();
for(int i = 0, len = files.length; i < len; i++) {
File f = new File(dir, files[i]);
if(f.isDirectory()) {
deleteDirectory(f);
}else {
f.delete();
}
}
return dir.delete();
}
ActiveModel::Dirty
didn't work for me because the @model.update_attributes()
hid the changes. So this is how I detected changes it in an update
method in a controller:
def update
@model = Model.find(params[:id])
detect_changes
if @model.update_attributes(params[:model])
do_stuff if attr_changed?
end
end
private
def detect_changes
@changed = []
@changed << :attr if @model.attr != params[:model][:attr]
end
def attr_changed?
@changed.include :attr
end
If you're trying to detect a lot of attribute changes it could get messy though. Probably shouldn't do this in a controller, but meh.
Check out -webkit-appearance: none and its derivatives. Originally described by Chris Coyer here: https://css-tricks.com/almanac/properties/a/appearance/
Bit late to this...I'm surprised that no one mentioned Symfony's VarDumper
component that Laravel includes, in part, for its dd()
(and lesser-known, dump()
) utility functions.
$dumpMe = new App\User([ 'name' => 'Cy Rossignol' ]);
(new Symfony\Component\VarDumper\Dumper\CliDumper())->dump(
(new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($dumpMe)
);
There's a bit more code needed, but, in return, we get nice formatted, readable output in the console—especially useful for debugging complex objects or arrays:
App\User {#17 #attributes: array:1 [ "name" => "Cy Rossignol" ] #fillable: array:3 [ 0 => "name" 1 => "email" 2 => "password" ] #guarded: array:1 [ 0 => "*" ] #primaryKey: "id" #casts: [] #dates: [] #relations: [] ... etc ... }
To take this a step further, we can even colorize the output! Add this helper function to the project to save some typing:
function toConsole($var)
{
$dumper = new Symfony\Component\VarDumper\Dumper\CliDumper();
$dumper->setColors(true);
$dumper->dump((new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($var));
}
If we're running the app behind a full webserver (like Apache or Nginx—not artisan serve
), we can modify this function slightly to send the dumper's prettified output to the log (typically storage/logs/laravel.log):
function toLog($var)
{
$lines = [ 'Dump:' ];
$dumper = new Symfony\Component\VarDumper\Dumper\CliDumper();
$dumper->setColors(true);
$dumper->setOutput(function ($line) use (&$lines) {
$lines[] = $line;
});
$dumper->dump((new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($var));
Log::debug(implode(PHP_EOL, $lines));
}
...and, of course, watch the log using:
$ tail -f storage/logs/laravel.log
PHP's error_log()
works fine for quick, one-off inspection of simple values, but the functions shown above take the hard work out of debugging some of Laravel's more complicated classes.
You need to create new TextNodes as well as td nodes for each column, not reuse them among all of the columns as your code is doing.
Edit: Revise your code like so:
for (var i = 1; i < 4; i++)
{
tr[i] = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
td1.appendChild(document.createTextNode('Text1'));
td2.appendChild(document.createTextNode('Text2'));
tr[i].appendChild(td1);
tr[i].appendChild(td2);
table.appendChild(tr[i]);
}
Try adding this to your where
clause:
dateadd(day, -30, getdate())
An alternative way to code Brettski's answer, with which I otherwise agree entirely, might be
With New FileSystemObject
If .FileExists(yourFilePath) Then
.DeleteFile yourFilepath
End If
End With
Same effect but fewer (well, none at all) variable declarations.
The FileSystemObject is a really useful tool and well worth getting friendly with. Apart from anything else, for text file writing it can actually sometimes be faster than the legacy alternative, which may surprise a few people. (In my experience at least, YMMV).
If you are actually looking for the index number (and not the value) of the selected option then it would be
document.forms[0].elements["CCards"].selectedIndex
/* You may need to change document.forms[0] to reference the correct form */
or using jQuery
$('select[name="CCards"]')[0].selectedIndex

Figured it out for myself in the end. It is simple, I was just missing the ** operator to unpack the dictionary
So my example becomes:

No, you can't use underscore in subdomain but hypen (dash). i.e my-subdomain.agahost.com is acceptable and my_subdomain.agahost.com would not be acceptable.
From your question it seems like you are using C99, as you have used %lf
for double.
To achieve the desired output replace:
sprintf(aa, "%lf", a);
with
sprintf(aa, "%0.7f", a);
The general syntax "%A.B"
means to use B digits after decimal point. The meaning of the A
is more complicated, but can be read about here.
I usually have it on a Makefile
:
# All .js compiled into a single one.
compiled=./path/of/js/main.js
compile:
@find ./path/of/js -type f -name "*.js" | xargs cat > $(compiled)
Then you run:
make compile
I hope it helps.
All the existing (working) answers have one of two problems:
1. Ignored Indices:
For the most part, when a column being searched has a function called on it (including implicitly, like for CAST
), the optimizer must ignore indices on the column and search through every record. Here's a quick example:
We're dealing with timestamps, and most RDBMSs tend to store this information as an increasing value of some sort, usually a long
or BIGINTEGER
count of milli-/nanoseconds. The current time thus looks/is stored like this:
1402401635000000 -- 2014-06-10 12:00:35.000000 GMT
You don't see the 'Year' value ('2014'
) in there, do you? In fact, there's a fair bit of complicated math to translate back and forth. So if you call any of the extraction/date part functions on the searched column, the server has to perform all that math just to figure out if you can include it in the results. On small tables this isn't an issue, but as the percentage of rows selected decreases this becomes a larger and larger drain. Then in this case, you're doing it a second time for asking about MONTH
... well, you get the picture.
2. Unintended data:
Depending on the particular version of SQL Server, and column datatypes, using BETWEEN
(or similar inclusive upper-bound ranges: <=
) can result in the wrong data being selected. Essentially, you potentially end up including data from midnight of the "next" day, or excluding some portion of the "current" day's records.
What you should be doing:
So we need a way that's safe for our data, and will use indices (if viable). The correct way is then of the form:
WHERE date_created >= @startOfPreviousMonth AND date_created < @startOfCurrentMonth
Given that there's only one month, @startOfPreviousMonth
can be easily substituted for/derived by:
DATEADD(month, -1, @startOCurrentfMonth)
If you need to derive the start-of-current-month in the server, you can do it via the following:
DATEADD(month, DATEDIFF(month, 0, CURRENT_TIMESTAMP), 0)
A quick word of explanation here. The initial DATEDIFF(...)
will get the difference between the start of the current era (0001-01-01
- AD, CE, whatever), essentially returning a large integer. This is the count of months to the start of the current month. We then add this number to the start of the era, which is at the start of the given month.
So your full script could/should look similar to the following:
DECLARE @startOfCurrentMonth DATETIME
SET @startOfCurrentMonth = DATEADD(month, DATEDIFF(month, 0, CURRENT_TIMESTAMP), 0)
SELECT *
FROM Member
WHERE date_created >= DATEADD(month, -1, @startOfCurrentMonth) -- this was originally misspelled
AND date_created < @startOfCurrentMonth
All date operations are thus only performed once, on one value; the optimizer is free to use indices, and no incorrect data will be included.

Easy to use, supports not well formed HTML, a lot of examples.
this question is a bit old, but I will post my answer. I have tested various INI classes (you can see them on my website) and I also use simpleIni because I want to work with INI files on both windows and winCE. Window's GetPrivateProfileString() works only with the registry on winCE.
It is very easy to read with simpleIni. Here is an example:
#include "SimpleIni\SimpleIni.h"
CSimpleIniA ini;
ini.SetUnicode();
ini.LoadFile(FileName);
const char * pVal = ini.GetValue(section, entry, DefaultStr);
This is not possible the way you are trying it. The Jackson unmarshalling works on the compiled java code after type erasure. So your
public @ResponseBody ModelMap setTest(@RequestBody List<TestS> refunds, ModelMap map)
is really only
public @ResponseBody ModelMap setTest(@RequestBody List refunds, ModelMap map)
(no generics in the list arg).
The default type Jackson creates when unmarshalling a List
is a LinkedHashMap
.
As mentioned by @Saint you can circumvent this by creating your own type for the list like so:
class TestSList extends ArrayList<TestS> { }
and then modifying your controller signature to
public @ResponseBody ModelMap setTest(@RequestBody TestSList refunds, ModelMap map) {
You need to that in two steps, at least.
First, click on the ยถ symbol in the toolbar: you can see if you have CRLF
line endings or just LF
.
Click on the Replace button, and put \r\n
or \n
, depending on the kind of line ending. In the Search Mode section of the dialog, check Extended radio button (interpret \n
and such).
Then replace all occurrences with nothing (empty string).
You end with a big line...
Next, in the same Replace dialog, put your delimiter (</Row>
) for example and in the Replace With field, put the same with a line ending (</Row>\r\n
). Replace All, and you are done.
fscanf
will treat 2 arguments, and thus return 2. Your while statement will be false, hence never displaying what has been read, plus as it has read only 1 line, if is not at EOF, resulting in what you see.
This code also works:
this.formGroup.controls.nameOfcontrol.value
By default, post_max_size should be 4 times greater than upload_max_filesize.
In turn
memory_limit should be 16 times greater than post_max_size
This answer attempts a pragmatic summary of the many great answers on this page:
jeb's great answer deserves special mention, because it really goes in-depth and covers many edge cases.
Notably, he points out that a misconstructed variable/parameter reference such as %~
can break any of the solutions below - including REM
lines.
REM
(or case variations thereof) is the only official comment construct, and is the safest choice - see Joey's helpful answer.
::
is a (widely used) hack, which has pros and cons:
Pros:
Cons:
(...)
blocks, ::
can break the command, and the rules for safe use are restrictive and not easy to remember - see below.If you do want to use ::
, you have these choices:
(...)
blocks and use REM
there, or do not place comments inside (...)
altogether.::
inside (...)
, which are summarized in the following snippet:@echo off
for %%i in ("dummy loop") do (
:: This works: ONE comment line only, followed by a DIFFERENT, NONBLANK line.
date /t
REM If you followed a :: line directly with another one, the *2nd* one
REM would generate a spurious "The system cannot find the drive specified."
REM error message and potentially execute commands inside the comment.
REM In the following - commented-out - example, file "out.txt" would be
REM created (as an empty file), and the ECHO command would execute.
REM :: 1st line
REM :: 2nd line > out.txt & echo HERE
REM NOTE: If :: were used in the 2 cases explained below, the FOR statement
REM would *break altogether*, reporting:
REM 1st case: "The syntax of the command is incorrect."
REM 2nd case: ") was unexpected at this time."
REM Because the next line is *blank*, :: would NOT work here.
REM Because this is the *last line* in the block, :: would NOT work here.
)
Note that none of these styles are directly supported by the batch language, but can be emulated.
Inline comments:
* The code snippets below use ver
as a stand-in for an arbitrary command, so as to facilitate experimentation.
* To make SET
commands work correctly with inline comments, double-quote the name=value
part; e.g., SET "foo=bar"
.[1]
In this context we can distinguish two subtypes:
EOL comments ([to-the-]end-of-line), which can be placed after a command, and invariably extend to the end of the line (again, courtesy of jeb's answer):
ver & REM <comment>
takes advantage of the fact that REM
is a valid command and &
can be used to place an additional command after an existing one.ver & :: <comment>
works too, but is really only usable outside of (...)
blocks, because its safe use there is even more limited than using ::
standalone.Intra-line comments, which be placed between multiple commands on a line or ideally even inside of a given command.
Intra-line comments are the most flexible (single-line) form and can by definition also be used as EOL comments.
ver & REM^. ^<comment^> & ver
allows inserting a comment between commands (again, courtesy of jeb's answer), but note how <
and >
needed to be ^
-escaped, because the following chars. cannot be used as-is: < > |
(whereas unescaped &
or &&
or ||
start the next command).
%= <comment> =%
, as detailed in dbenham's great answer, is the most flexible form, because it can be placed inside a command (among the arguments).
It takes advantage of variable-expansion syntax in a way that ensures that the expression always expands to the empty string - as long as the comment text contains neither %
nor :
Like REM
, %= <comment> =%
works well both outside and inside (...)
blocks, but it is more visually distinctive; the only down-sides are that it is harder to type, easier to get wrong syntactically, and not widely known, which can hinder understanding of source code that uses the technique.
Multi-line (whole-line block) comments:
James K's answer shows how to use a goto
statement and a label to delimit a multi-line comment of arbitrary length and content (which in his case he uses to store usage information).
Zee's answer shows how to use a "null label" to create a multi-line comment, although care must be taken to terminate all interior lines with ^
.
Rob van der Woude's blog post mentions another somewhat obscure option that allows you to end a file with an arbitrary number of comment lines: An opening (
only causes everything that comes after to be ignored, as long as it doesn't contain a ( non-^
-escaped) )
, i.e., as long as the block is not closed.
[1] Using SET "foo=bar"
to define variables - i.e., putting double quotes around the name and =
and the value combined - is necessary in commands such as SET "foo=bar" & REM Set foo to bar.
, so as to ensure that what follows the intended variable value (up to the next command, in this case a single space) doesn't accidentally become part of it.
(As an aside: SET foo="bar"
would not only not avoid the problem, it would make the double quotes part of the value).
Note that this problem is inherent to SET
and even applies to accidental trailing whitespace following the value, so it is advisable to always use the SET "foo=bar"
approach.

You may be overcomplicating things, is there any reason you need the stringr package?
df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
as.Date(df$Date, "%m/%d/%Y %H:%M:%S")
[1] "2009-10-09" "2009-10-15"
More generally and if you need the time component as well, use strptime:
strptime(df$Date, "%m/%d/%Y %H:%M:%S")
I'm guessing at what your actual data might look at from the partial results you give.
All previous answers which I checked would list the files to be committed, too.
Here is a simple and easy solution that only lists files which are not yet in the
repo and not subject to .gitignore
.
git status --porcelain | awk '/^\?\?/ { print $2; }'
or
git status --porcelain | grep -v '\?\?'
I haven't had a problem just using Unix-style path separators, even on Windows (though it is good practice to check File.separatorChar).
The technique of using ClassLoader.getResource() is best for read-only resources that are going to be loaded from JAR files. Sometimes, you can programmatically determine the application directory, which is useful for admin-configurable files or server applications. (Of course, user-editable files should be stored somewhere in the System.getProperty("user.home") directory.)
function page_title($val){
include(dirname(__FILE__).'/simple_html_dom.php');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$val);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0');
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$return = curl_exec($ch);
$encot = false;
$charset = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
curl_close($ch);
$html = str_get_html('"'.$return.'"');
if(strpos($charset,'charset=') !== false) {
$c = str_replace("text/html; charset=","",$charset);
$encot = true;
}
else {
$lookat=$html->find('meta[http-equiv=Content-Type]',0);
$chrst = $lookat->content;
preg_match('/charset=(.+)/', $chrst, $found);
$p = trim($found[1]);
if(!empty($p) && $p != "")
{
$c = $p;
$encot = true;
}
}
$title = $html->find('title')[0]->innertext;
if($encot == true && $c != 'utf-8' && $c != 'UTF-8') $title = mb_convert_encoding($title,'UTF-8',$c);
return $title;
}
Or you can create an empty link at the end of your <li>
:
<a href="link"></a>
.menu li{position:relative;padding:0;}
.link{
bottom: 0;
left: 0;
position: absolute;
right: 0;
top: 0;
}
This will create a full clickable <li>
and keep your formatting on your real link.
It could be useful for <div>
tag as well
These are placeholders:
For example: 'Hi %s I have %d donuts' %('Alice', 42)
This line of code will substitute %s with Alice (str) and %d with 42.
Output: 'Hi Alice I have 42 donuts'
This could be achieved with a "+" most of the time. To gain a deeper understanding to your question, you may want to check {} / .format() as well. Here is one example: Python string formatting: % vs. .format

To include CSS and jQuery in your plugin is easy, try this:
// register jquery and style on initialization
add_action('init', 'register_script');
function register_script() {
wp_register_script( 'custom_jquery', plugins_url('/js/custom-jquery.js', __FILE__), array('jquery'), '2.5.1' );
wp_register_style( 'new_style', plugins_url('/css/new-style.css', __FILE__), false, '1.0.0', 'all');
}
// use the registered jquery and style above
add_action('wp_enqueue_scripts', 'enqueue_style');
function enqueue_style(){
wp_enqueue_script('custom_jquery');
wp_enqueue_style( 'new_style' );
}
I found this great snipped from this site How to include jQuery and CSS in WordPress โ The WordPress Way
Hope that helps.
I have a very well working solution for tables of max-width: 100%
.
Just use word-break: break-all;
for the table cells (except heading cells) to break all long text into several lines:
<!DOCTYPE html>
<html>
<head>
<style>
table {
max-width: 100%;
}
table td {
word-break: break-all;
}
</style>
</head>
<body>
<table border="1">
<tr>
<th><strong>Input</strong></th>
<th><strong>Output</strong></th>
</tr>
<tr>
<td>some text</td>
<td>12b6459fc6b4cabb4b1990be1a78e4dc5fa79c3a0fe9aa9f0386d673cfb762171a4aaa363b8dac4c33e0ad23e4830888</td>
</tr>
</table>
</body>
</html>
This will render like this (when the screen width is limited):
Unless I am greatly mistaken, the answer is, "No, there is no way."
The basic problem in situations like that is the fact that you are calling a MySQL function and you're not actually setting a value. CI escapes values so that you can do a clean insert but it does not test to see if those values happen to be calling functions like aes_encrypt
, md5
, or (in this case) now()
. While in most situations this is wonderful, for those situations raw sql is the only recourse.
On a side, date('Y-m-d');
should work as a PHP version of NOW()
for MySQL. (It won't work for all versions of SQL though).
According to the Java Language Specification (specifically ยง10.7 Array Members) it is a field:
- The
public
final
fieldlength
, which contains the number of components of the array (length may be positive or zero).
Internally the value is probably stored somewhere in the object header, but that is an implementation detail and depends on the concrete JVM implementation.
The HotSpot VM (the one in the popular Oracle (formerly Sun) JRE/JDK) stores the size in the object-header:
[...] arrays have a third header field, for the array size.
I believe enum have a .name() in its API, pretty simple to use like this example:
private int security;
public String security(){ return Security.values()[security].name(); }
public void setSecurity(int security){ this.security = security; }
private enum Security {
low,
high
}
With this you can simply call
yourObject.security()
and it returns high/low as String, in this example
I know it's a bit late and maybe you already, indirectly, said it, but again, Kafka is not a queue at all, it's a log (as someone said above, poll based).
To make it simple, the most obvious use case when you should prefer RabbitMQ (or any queue techno) over Kafka is the following one :
You have multiple consumers consuming from a queue and whenever there is a new message in the queue and an available consumer, you want this message to be processed. If you look closely at how Kafka works, you'll notice it does not know how to do that, because of partition scaling, you'll have a consumer dedicated to a partition and you'll get into starvation issue. Issue that is easily avoided by using simple queue techno. You can think of using a thread that will dispatch the different messages from same partition, but again, Kafka does not have any selective acknowledgment mechanisms.
The most you could do is doing as those guys and try to transform Kafka as a queue : https://github.com/softwaremill/kmq

Using the index:
df[1:4,]
Where the values in the parentheses can be interpreted as either logical, numeric, or character (matching the respective names):
df[row.index, column.index]
Read help(`[`) for more detail on this subject, and also read about index matrices in the Introduction to R.
One option is to use bouncycastle's PEMParser:
Class for parsing OpenSSL PEM encoded streams containing X509 certificates, PKCS8 encoded keys and PKCS7 objects.
In the case of PKCS7 objects the reader will return a CMS ContentInfo object. Public keys will be returned as well formed SubjectPublicKeyInfo objects, private keys will be returned as well formed PrivateKeyInfo objects. In the case of a private key a PEMKeyPair will normally be returned if the encoding contains both the private and public key definition. CRLs, Certificates, PKCS#10 requests, and Attribute Certificates will generate the appropriate BC holder class.

This returns an absolute difference in days between some Date
and today:
extension Date {
func daysFromToday() -> Int {
return abs(Calendar.current.dateComponents([.day], from: self, to: Date()).day!)
}
}
and then use it:
if someDate.daysFromToday() >= 7 {
// at least a week from today
}
The most up-voted solution did not work for me. I have date pickers with default of disabled, which works fine. When it comes time to enable them in the window.onload function, though, the $("#award_start_date").datepicker( 'enable' ); syntax did not enable the widgets. I was able to edit the field as if it were a text input field, but did not get the calendar chooser.
What does work is this:
if (x[i].id == "award_start_date") {
$("#award_start_date").datepicker( {enabled: true} );
}
if (x[i].id == "award_end_date") {
$("#award_end_date").datepicker( {enabled: true} );
}
It may be that this simply recreates the datepickers, but for my purposes, that is fine.
This is my second day using jQuery UI awesomeness, so I may be missing some of the finer points...
It reads the existing .config
file that was used for an old kernel and prompts the user for options in the current kernel source that are not found in the file. This is useful when taking an existing configuration and moving it to a new kernel.
console.log( 'You are running jQuery version: ' + $.fn.jquery );
You can use facet_wrap(~ variable, ncol= )
on a variable to create a new comparison. It's not on the same axis, but it is similar.

If I understand you, perhaps you don't need an array of zeroes; rather, you need a hash. The hash keys will be the values in the other array and the hash values will be the number of times the value exists in the other array:
use strict;
use warnings;
my @other_array = (0,0,0,1,2,2,3,3,3,4);
my %tallies;
$tallies{$_} ++ for @other_array;
print "$_ => $tallies{$_}\n" for sort {$a <=> $b} keys %tallies;
Output:
0 => 3
1 => 1
2 => 2
3 => 3
4 => 1
To answer your specific question more directly, to create an array populated with a bunch of zeroes, you can use the technique in these two examples:
my @zeroes = (0) x 5; # (0,0,0,0,0)
my @zeroes = (0) x @other_array; # A zero for each item in @other_array.
# This works because in scalar context
# an array evaluates to its size.
So, you want to exclude firstName
and country.name
. Here is what your ExclusionStrategy
should look like
public class TestExclStrat implements ExclusionStrategy {
public boolean shouldSkipClass(Class<?> arg0) {
return false;
}
public boolean shouldSkipField(FieldAttributes f) {
return (f.getDeclaringClass() == Student.class && f.getName().equals("firstName"))||
(f.getDeclaringClass() == Country.class && f.getName().equals("name"));
}
}
If you see closely it returns true
for Student.firstName
and Country.name
, which is what you want to exclude.
You need to apply this ExclusionStrategy
like this,
Gson gson = new GsonBuilder()
.setExclusionStrategies(new TestExclStrat())
//.serializeNulls() <-- uncomment to serialize NULL fields as well
.create();
Student src = new Student();
String json = gson.toJson(src);
System.out.println(json);
This returns:
{ "middleName": "J.", "initials": "P.F", "lastName": "Fry", "country": { "id": 91}}
I assume the country object is initialized with id = 91L
in student class.
You may get fancy. For example, you do not want to serialize any field that contains "name" string in its name. Do this:
public boolean shouldSkipField(FieldAttributes f) {
return f.getName().toLowerCase().contains("name");
}
This will return:
{ "initials": "P.F", "country": { "id": 91 }}
EDIT: Added more info as requested.
This ExclusionStrategy
will do the thing, but you need to pass "Fully Qualified Field Name". See below:
public class TestExclStrat implements ExclusionStrategy {
private Class<?> c;
private String fieldName;
public TestExclStrat(String fqfn) throws SecurityException, NoSuchFieldException, ClassNotFoundException
{
this.c = Class.forName(fqfn.substring(0, fqfn.lastIndexOf(".")));
this.fieldName = fqfn.substring(fqfn.lastIndexOf(".")+1);
}
public boolean shouldSkipClass(Class<?> arg0) {
return false;
}
public boolean shouldSkipField(FieldAttributes f) {
return (f.getDeclaringClass() == c && f.getName().equals(fieldName));
}
}
Here is how we can use it generically.
Gson gson = new GsonBuilder()
.setExclusionStrategies(new TestExclStrat("in.naishe.test.Country.name"))
//.serializeNulls()
.create();
Student src = new Student();
String json = gson.toJson(src);
System.out.println(json);
It returns:
{ "firstName": "Philip" , "middleName": "J.", "initials": "P.F", "lastName": "Fry", "country": { "id": 91 }}
And here is the one liner:
$("<li><div class='bar'>bla</div></li>").find("li").attr("id","1234").end().appendTo("body")
But I'm wondering why you would like to add the "id" attribute at a later stage rather than injecting it directly in the template.
I just experienced this same problem and it turned out that my problem was not in the php.ini files, but simply, that I was starting the apache server as a regular user. As soon as i did a "sudo /etc/init.d/apache2 restart", my errors were shown.
If you're treating it as a tuple (see section 3.3.3 of the language spec), then:
var t:[number, string] = [1, "message"]
or
interface NumberStringTuple extends Array<string|number>{0:number; 1:string}
var t:NumberStringTuple = [1, "message"];
Ruslik's suggestion to use source generation seems like a good thing to me. However, I wouldn't go with the concept of "main" and "generated" source files. I'd rather have one file with code almost identical to yours:
h=_myhash (mystring);
switch (h)
{
case 66452: // = hash("Vasia")
.......
case 1342537: // = hash("Petya")
........
}
The next thing I'd do, I'd write a simple script. Perl is good for such kind of things, but nothing stops you even from writing a simple program in C/C++ if you don't want to use any other languages. This script, or program, would take the source file, read it line-by-line, find all those case NUMBERS: // = hash("SOMESTRING")
lines (use regular expressions here), replace NUMBERS with the actual hash value and write the modified source into a temporary file. Finally, it would back up the source file and replace it with the temporary file. If you don't want your source file to have a new time stamp each time, the program could check if something was actually changed and if not, skip the file replacement.
The last thing to do is to integrate this script into the build system used, so you won't accidentally forget to launch it before building the project.
Good point that view is appeared if it's already in window hierarchy stack. thus we can extend our classes for this functionality.
extension UIViewController {
var isViewAppeared: Bool { viewIfLoaded?.isAppeared == true }
}
extension UIView {
var isAppeared: Bool { window != nil }
}
You're pretty much right about cout
and cin
. They are objects (not functions) defined inside the std
namespace. Here are their declarations as defined by the C++ standard:
Header
<iostream>
synopsis#include <ios> #include <streambuf> #include <istream> #include <ostream> namespace std { extern istream cin; extern ostream cout; extern ostream cerr; extern ostream clog; extern wistream wcin; extern wostream wcout; extern wostream wcerr; extern wostream wclog; }
::
is known as the scope resolution operator. The names cout
and cin
are defined within std
, so we have to qualify their names with std::
.
Classes behave a little like namespaces in that the names declared inside the class belong to the class. For example:
class foo
{
public:
foo();
void bar();
};
The constructor named foo
is a member of the class named foo
. They have the same name because its the constructor. The function bar
is also a member of foo
.
Because they are members of foo
, when referring to them from outside the class, we have to qualify their names. After all, they belong to that class. So if you're going to define the constructor and bar
outside the class, you need to do it like so:
foo::foo()
{
// Implement the constructor
}
void foo::bar()
{
// Implement bar
}
This is because they are being defined outside the class. If you had not put the foo::
qualification on the names, you would be defining some new functions in the global scope, rather than as members of foo
. For example, this is entirely different bar
:
void bar()
{
// Implement different bar
}
It's allowed to have the same name as the function in the foo
class because it's in a different scope. This bar
is in the global scope, whereas the other bar
belonged to the foo
class.
For serializable deep clone, with Type Information is,
export function clone<T>(a: T): T {
return JSON.parse(JSON.stringify(a));
}
Not exactly in-place, but some idea to do it:
a = ['a', 'b']
def inplace(a):
c = []
while len(a) > 0:
e = a.pop(0)
if e == 'b':
c.append(e)
a.extend(c)
You can extend the function to call you filter in the condition.
That syntax works fine for me:
CREATE FUNCTION dbo.test_func
(@in varchar(20))
RETURNS INT
AS
BEGIN
RETURN 1
END
GO
SELECT dbo.test_func('blah')
Are you sure that the function exists as a function and under the dbo schema?
Instead of adding Reader("Name")
you add a new ListItem
. ListItem
has a Text
and a Value
property that you can set.
Here is an approach that to me seems quite straightforward, and easier that adding an AttachedBehaviour (which is also a valid solution). We use the default UpdateSourceTrigger (LostFocus for TextBox), and then add an InputBinding to the Enter Key, bound to a command.
The xaml is as follows
<TextBox Grid.Row="0" Text="{Binding Txt1}" Height="30" Width="150">
<TextBox.InputBindings>
<KeyBinding Gesture="Enter"
Command="{Binding UpdateText1Command}"
CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}},Path=Text}" />
</TextBox.InputBindings>
</TextBox>
Then the Command methods are
Private Function CanExecuteUpdateText1(ByVal param As Object) As Boolean
Return True
End Function
Private Sub ExecuteUpdateText1(ByVal param As Object)
If TypeOf param Is String Then
Txt1 = CType(param, String)
End If
End Sub
And the TextBox is bound to the Property
Public Property Txt1 As String
Get
Return _txt1
End Get
Set(value As String)
_txt1 = value
OnPropertyChanged("Txt1")
End Set
End Property
So far this seems to work well and catches the Enter Key event in the TextBox.
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(foo);
foreach (PropertyDescriptor property in properties)
{
if (property.Name == "Name")
{
Console.WriteLine(property.DisplayName); // Something To Name
}
}
where foo
is an instance of Class1
td image
{
display: block;
margin-left: auto;
margin-right: auto;
}
If you want a module to simply never be cached (sometimes useful for development, but remember to remove it when done!) you can just put delete require.cache[module.id];
inside the module.
I took the liberty of putting together a jsFiddle illustrating the functionality of building a custom form using jQuery. Here it is...
EDIT: Updated the jsFiddle to include remove buttons for each field.
EDIT: As per the request in the last comment, code from the jsFiddle is below.
EDIT: As per Abhishek's comment, I have updated the jsFiddle (and code below) to cater for scenarios where duplicate field IDs might arise.
HTML:
<fieldset id="buildyourform">
<legend>Build your own form!</legend>
</fieldset>
<input type="button" value="Preview form" class="add" id="preview" />
<input type="button" value="Add a field" class="add" id="add" />
JavaScript:
$(document).ready(function() {
$("#add").click(function() {
var lastField = $("#buildyourform div:last");
var intId = (lastField && lastField.length && lastField.data("idx") + 1) || 1;
var fieldWrapper = $("<div class=\"fieldwrapper\" id=\"field" + intId + "\"/>");
fieldWrapper.data("idx", intId);
var fName = $("<input type=\"text\" class=\"fieldname\" />");
var fType = $("<select class=\"fieldtype\"><option value=\"checkbox\">Checked</option><option value=\"textbox\">Text</option><option value=\"textarea\">Paragraph</option></select>");
var removeButton = $("<input type=\"button\" class=\"remove\" value=\"-\" />");
removeButton.click(function() {
$(this).parent().remove();
});
fieldWrapper.append(fName);
fieldWrapper.append(fType);
fieldWrapper.append(removeButton);
$("#buildyourform").append(fieldWrapper);
});
$("#preview").click(function() {
$("#yourform").remove();
var fieldSet = $("<fieldset id=\"yourform\"><legend>Your Form</legend></fieldset>");
$("#buildyourform div").each(function() {
var id = "input" + $(this).attr("id").replace("field","");
var label = $("<label for=\"" + id + "\">" + $(this).find("input.fieldname").first().val() + "</label>");
var input;
switch ($(this).find("select.fieldtype").first().val()) {
case "checkbox":
input = $("<input type=\"checkbox\" id=\"" + id + "\" name=\"" + id + "\" />");
break;
case "textbox":
input = $("<input type=\"text\" id=\"" + id + "\" name=\"" + id + "\" />");
break;
case "textarea":
input = $("<textarea id=\"" + id + "\" name=\"" + id + "\" ></textarea>");
break;
}
fieldSet.append(label);
fieldSet.append(input);
});
$("body").append(fieldSet);
});
});
CSS:

Andy E is correct that there is no HTML-based way to do this*; but if you are willing to use Flash, you can do it. The following works reliably on systems that have Flash installed. If your app needs to work on iPhone, then of course you'll need a fallback HTML-based solution.
* (Update 4/22/2013: HTML does now support this, in HTML5. See the other answers.)
Flash uploading also has other advantages -- Flash gives you the ability to show a progress bar as the upload of a large file progresses. (I'm pretty sure that's how Gmail does it, by using Flash behind the scenes, although I may be wrong about that.)
Here is a sample Flex 4 app that allows the user to pick a file, and then displays it:

</fx:Declarations>
<s:Button x="10" y="10" label="Choose file..." click="showFilePicker()" />
<mx:Image id="myImage" x="9" y="44"/>

here are few differences between Comparator and Comparable I found on web :
If you see then logical difference between these two is Comparator in Java compare two objects provided to him, while Comparable interface compares "this" reference with the object specified.
Comparable in Java is used to implement natural ordering of object. In Java API String, Date and wrapper classes implement Comparable interface.
If any class implement Comparable interface in Java then collection of that object either List or Array can be sorted automatically by using Collections.sort() or Array.sort() method and object will be sorted based on there natural order defined by CompareTo method.
Objects which implement Comparable in Java can be used as keys in a sorted map or elements in a sorted set for example TreeSet, without specifying any Comparator.

My problem was I was modifying the settings for the wrong version of my app.
I had "Debug" selected instead of "Release", so my bundle identifier was not accurate when it came time to Archive.
You can list all existing tags git tag
or you could filter the list with git tag -l 'v1.1.*'
, where *
acts as a wildcard. It will return a list of tags marked with v1.1
.
You will notice that when you call git tag
you do not get to see the contents of your annotations. To preview them you must add -n
to your command: git tag -n2
.
$ git tag -l -n2
v1.0 Release version 1.0
v1.1 Release version 1.1
The command lists all existing tags with maximum 3 lines of their tag message. By default -n
only shows the first line. For more info be sure to check this tag related article as well.
Use a subselect:
select name, date, time
from mytable main
where date + time = (select min(date + time) from mytable where name = main.mytable)
order by date + time;
Personally I feel that the query string method is more reliable than trying to set headers on the server - there's no guarantee that a proxy or browser won't just cache it anyway (some browsers are worse than others - naming no names).
I usually use Math.random()
but I don't see anything wrong with using the date (you shouldn't be doing AJAX requests fast enough to get the same value twice).
To get the type, use the builtin type
function. With the in
operator, you can test if the type is a numpy type by checking if it contains the string numpy
;
In [1]: import numpy as np
In [2]: a = np.array([1, 2, 3])
In [3]: type(a)
Out[3]: <type 'numpy.ndarray'>
In [4]: 'numpy' in str(type(a))
Out[4]: True
(This example was run in IPython, by the way. Very handy for interactive use and quick tests.)
I figured out a way that works for me. It does require the use of a scratch table that a linked server has access to though.
I created a table and populated it with the values I need then I reference that table through a linked server.
SELECT *
FROM OPENQUERY(KHSSQLODSPRD,'SELECT *
FROM ABC.dbo.CLAIM A WITH (NOLOCK)
WHERE A.DOS >= (SELECT MAX(DATE) FROM KHSDASQL01.DA_MAIN.[dbo].[ALLFILENAMES]) ')
EDIT:
Indeed there was a patch which included sign()
in math, but it wasn't accepted, because they didn't agree on what it should return in all the edge cases (+/-0, +/-nan, etc)
So they decided to implement only copysign, which (although more verbose) can be used to delegate to the end user the desired behavior for edge cases - which sometimes might require the call to cmp(x,0)
.
I don't know why it's not a built-in, but I have some thoughts.
copysign(x,y):
Return x with the sign of y.
Most importantly, copysign
is a superset of sign
! Calling copysign
with x=1 is the same as a sign
function. So you could just use copysign
and forget about it.
>>> math.copysign(1, -4)
-1.0
>>> math.copysign(1, 3)
1.0
If you get sick of passing two whole arguments, you can implement sign
this way, and it will still be compatible with the IEEE stuff mentioned by others:
>>> sign = functools.partial(math.copysign, 1) # either of these
>>> sign = lambda x: math.copysign(1, x) # two will work
>>> sign(-4)
-1.0
>>> sign(3)
1.0
>>> sign(0)
1.0
>>> sign(-0.0)
-1.0
>>> sign(float('nan'))
-1.0
Secondly, usually when you want the sign of something, you just end up multiplying it with another value. And of course that's basically what copysign
does.
So, instead of:
s = sign(a)
b = b * s
You can just do:
b = copysign(b, a)
And yes, I'm surprised you've been using Python for 7 years and think cmp
could be so easily removed and replaced by sign
! Have you never implemented a class with a __cmp__
method? Have you never called cmp
and specified a custom comparator function?
In summary, I've found myself wanting a sign
function too, but copysign
with the first argument being 1 will work just fine. I disagree that sign
would be more useful than copysign
, as I've shown that it's merely a subset of the same functionality.
As of current edited version of the post, you call setInterval
at each change's end, adding a new "changer" with each new iterration. That means after first run, there's one of them ticking in memory, after 100 runs, 100 different changers change image 100 times every second, completely destroying performance and producing confusing results.
You only need to "prime" setInterval
once. Remove it from function and place it inside onload
instead of direct function call.
You don't need to replace it with anything. The setting magic_quotes_runtime
is removed in PHP6 so the function call is unneeded. If you want to maintain backwards compatibility it may be wise to wrap it in a if statement checking phpversion using version_compare
In my case, my index.js
just points to another js instead of my Launcher js mistakenly, which does not contain AppRegistry.registerComponent()
.
So, make sure the file yourindex.js
point to register the class.
Try using SweetAlert its just simply the best . You will get a lot of customization and flexibility.
