I have all of my .ts files inside a src
folder that is a sibling of my tsconfig.json
. I was getting this error when my include
looked like this (it was working before, some dependency upgrade caused the error showing up):
"include": [
"src/**/*"
],
changing it to this fixed the problem for me:
"include": [
"**/*"
],
Assuming you already have a JFrame to call this from:
JOptionPane.showMessageDialog(frame, "thank you for using java");
What it is: A class for which there is just one, persistent instance across the lifetime of an application. See Singleton Pattern.
When you should use it: As little as possible. Only when you are absolutely certain that you need it. I'm reluctant to say "never", but there is usually a better alternative, such as Dependency Injection or simply a static class.
if (Form.ModifierKeys == Keys.Shift)
does work for a text box if the above code is in the form's keydown event and no other control captures the keydown event for the key down.
Also one may wish stop further key processing with:
e.Handled = true;
Change your gmail password and try again, it should work after that.
Don't know why, but every time you change your hosting you have to change your password.
While Parallels is technically a VM it is capable of running games in high resolution at a high frame rate. If you run Parallels in Coherence mode it completely integrates Windows 7 into OS X and .Net framework is fully supported. So yes you can install Visual Studio on your Mac however the Apps you created would only run of windows computers unless they were web based.
the $("body").append(r)
statement should be within the test
function, also there was misplaced "
in the test
method
function test() {
var r=$('<input/>').attr({
type: "button",
id: "field",
value: 'new'
});
$("body").append(r);
}
Demo: Fiddle
Update
In that case try a more jQuery-ish solution
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
jQuery(function($){
$('#mybutton').one('click', function(){
var r=$('<input/>').attr({
type: "button",
id: "field",
value: 'new'
});
$("body").append(r);
})
})
</script>
</head>
<body>
<button id="mybutton">Insert after</button>
</body>
</html>
Demo: Plunker
Place the configuration information in a encrypted config file. Query this info in your code using an key. Place this key in a separate file per environment, and don't store it with your code.
Interesting. I got the same problem as you when I wrote a test version.
The solution is to use jquery's ability to chain and do:
$(this).width(500).css("text-align", "center");
Interesting find though.
To expand a bit, the following does not work
$(this).width(500);
$(this).css("text-align", "center");
and results only in the width being set on the style. Chaining the two, as I suggested above, does seem to work.
use following it handles all cases:-
import re
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.3')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '.3')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.3sd')
a=re.match('((\d+[\.]\d*$)|(\.)\d+$)' , '2.3')
To redirect all http
requests to https
, you can use :
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [NE,L,R]
If mod-rewrite isn't enabled and you are on apache 2.4, you can also use a Redirect
inside if
directive to redirect http
requests to https
.
Apache 2.4.
<if "%{HTTPS} !~ /on/">
Redirect / https://www.example.com/
</if>
I figured it out through trial and error... the real chink in the armor was a little known setting in IIS in the Configuration Editor
for the website in
Section: system.webServer/security/authentication/windowsAuthentication
From: ApplicationHost.config <locationpath='ServerName/SiteName' />
called useAppPoolCredentials
(which is set to False
by default. Set this to True
and life becomes great again!!! Hope this saves pain for the next guy....
In my project I use following code:
$('#attribute').select2();
$('#attribute').bind('change', function(){
var $options = $();
for (var i in data) {
$options = $options.add(
$('<option>').attr('value', data[i].id).html(data[i].text)
);
}
$('#value').html($options).trigger('change');
});
Try to comment out the select2 part. The rest of the code will still work.
import requests
url = requests.get("http://yahoo.com")
htmltext = url.text
print(htmltext)
This will work similar to urllib.urlopen
.
A good way to avoid loading multiple CSS files or to have inline CSS is to hand a class to the body tag depending on the version of Internet Explorer. If you only need general IE hacks, you can do something like this, but it can be extended to be version specific:
<!--[if IE ]><body class="ie"><![endif]-->
<!--[if !IE]>--><body><!--<![endif]-->
Now in your css code, you can simply do:
.ie .abc {
position:absolute;
left:30;
top:-10;
}
This also keeps your CSS files valid, as you do not have to use dirty (and invalid) CSS hacks.
The data.table
package also has unique
and duplicated
methods of it's own with some additional features.
Both the unique.data.table
and the duplicated.data.table
methods have an additional by
argument which allows you to pass a character
or integer
vector of column names or their locations respectively
library(data.table)
DT <- data.table(id = c(1,1,1,2,2,2),
val = c(10,20,30,10,20,30))
unique(DT, by = "id")
# id val
# 1: 1 10
# 2: 2 10
duplicated(DT, by = "id")
# [1] FALSE TRUE TRUE FALSE TRUE TRUE
Another important feature of these methods is a huge performance gain for larger data sets
library(microbenchmark)
library(data.table)
set.seed(123)
DF <- as.data.frame(matrix(sample(1e8, 1e5, replace = TRUE), ncol = 10))
DT <- copy(DF)
setDT(DT)
microbenchmark(unique(DF), unique(DT))
# Unit: microseconds
# expr min lq mean median uq max neval cld
# unique(DF) 44708.230 48981.8445 53062.536 51573.276 52844.591 107032.18 100 b
# unique(DT) 746.855 776.6145 2201.657 864.932 919.489 55986.88 100 a
microbenchmark(duplicated(DF), duplicated(DT))
# Unit: microseconds
# expr min lq mean median uq max neval cld
# duplicated(DF) 43786.662 44418.8005 46684.0602 44925.0230 46802.398 109550.170 100 b

You can use
ls -lrt -d -1 "$PWD"/{*,.*}
It will also catch hidden files.
Use real two-factor authentication to avoid the sole dependency on passwords which might be stored in many more places than the user's browser cache.
Use the hex code for a non-breaking space. Something like this:
.breadcrumbs a:before {
content: '>\00a0';
}
simpler is better - make sense?
in this case just members[0] = 0 works. don't make a simple question so complicated.

XAMPP is more powerful and resource taking than WAMP.
WAMP provides support for MySQL and PHP.
XAMPP provides support for MYSQL, PHP and PERL
XAMPP also has SSL feature while WAMP doesnt.
If your applications need to deal with native web apps only, Go for WAMP.
If you need advanced features as stated above, go for XAMPP.
As of priority, you cant run both together with default installation as XAMPP gets a higher priority and it takes up ports. So WAMP cant be run in parallel with XAMPP.
This is the format of /etc/crontab:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# | | | | |
# * * * * * user-name command to be executed
I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.
To run something every minute:
* * * * * username /var/www/html/a.php
To run something at midnight of every day:
0 0 * * * username /var/www/html/reset.php
You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:
chmod +x file.php
Start your php file with a shebang so that your shell knows which interpreter to use:
#!/usr/bin/php
<?php
// your code here
Based on your question:
My question is, using the code below, how would you be able to have multiple clients connected? I've tried lists, but I just can't figure out the format for that. How can this be accomplished where multiple clients are connected at once and I am able to send a message to a specific client?
Using the code you gave, you can do this:
#!/usr/bin/python # This is server.py file
import socket # Import socket module
import thread
def on_new_client(clientsocket,addr):
while True:
msg = clientsocket.recv(1024)
#do some checks and if msg == someWeirdSignal: break:
print addr, ' >> ', msg
msg = raw_input('SERVER >> ')
#Maybe some code to compute the last digit of PI, play game or anything else can go here and when you are done.
clientsocket.send(msg)
clientsocket.close()
s = socket.socket() # Create a socket object
host = socket.gethostname() # Get local machine name
port = 50000 # Reserve a port for your service.
print 'Server started!'
print 'Waiting for clients...'
s.bind((host, port)) # Bind to the port
s.listen(5) # Now wait for client connection.
print 'Got connection from', addr
while True:
c, addr = s.accept() # Establish connection with client.
thread.start_new_thread(on_new_client,(c,addr))
#Note it's (addr,) not (addr) because second parameter is a tuple
#Edit: (c,addr)
#that's how you pass arguments to functions when creating new threads using thread module.
s.close()
As Eli Bendersky mentioned, you can use processes instead of threads, you can also check python threading
module or other async sockets framework. Note: checks are left for you to implement how you want and this is just a basic framework.
For example folder named new under E: drive
type the command:
e:\cd new
e:\new\attrib *.* -s -h /s /d
and all the files and folders are un-hidden
The use
operator is for giving aliases to names of classes, interfaces or other namespaces. Most use
statements refer to a namespace or class that you'd like to shorten:
use My\Full\Namespace;
is equivalent to:
use My\Full\Namespace as Namespace;
// Namespace\Foo is now shorthand for My\Full\Namespace\Foo
If the use
operator is used with a class or interface name, it has the following uses:
// after this, "new DifferentName();" would instantiate a My\Full\Classname
use My\Full\Classname as DifferentName;
// global class - making "new ArrayObject()" and "new \ArrayObject()" equivalent
use ArrayObject;
The use
operator is not to be confused with autoloading. A class is autoloaded (negating the need for include
) by registering an autoloader (e.g. with spl_autoload_register
). You might want to read PSR-4 to see a suitable autoloader implementation.
Here's a way to do this using TPL. No need to create/dispose of a timer, etc:
void ScheduleSomething()
{
var runAt = DateTime.Today + TimeSpan.FromHours(16);
if (runAt <= DateTime.Now)
{
DoSomething();
}
else
{
var delay = runAt - DateTime.Now;
System.Threading.Tasks.Task.Delay(delay).ContinueWith(_ => DoSomething());
}
}
void DoSomething()
{
// do somethig
}
If you need to do it dynamically in the browser using javascript, here is an example...
<img id=graph alt=""
src="http://www.kitco.com/images/live/gold.gif"
/>
<script language="javascript" type="text/javascript">
var d = new Date();
document.getElementById("graph").src =
"http://www.kitco.com/images/live/gold.gif?ver=" +
d.getTime();
</script>
Like said Gumbo,
<?php
$fruits = array('apple', 'banana', 'cranberry');
echo end($fruits); // cranberry
?>
This is a follow up to my original question to help out others with the same problem. If you need to filter by an attribute, rather than manually looking up the id you can use the following code to retrieve all the id, value pairs for an attribute. The data is returned as an array with the attribute name as the key.
function getAttributeOptions($attributeName) {
$product = Mage::getModel('catalog/product');
$collection = Mage::getResourceModel('eav/entity_attribute_collection')
->setEntityTypeFilter($product->getResource()->getTypeId())
->addFieldToFilter('attribute_code', $attributeName);
$_attribute = $collection->getFirstItem()->setEntity($product->getResource());
$attribute_options = $_attribute->getSource()->getAllOptions(false);
foreach($attribute_options as $val) {
$attrList[$val['label']] = $val['value'];
}
return $attrList;
}
Here is a function you can use to get products by their attribute set id. Retrieved using the previous function.
function getProductsByAttributeSetId($attributeSetId) {
$products = Mage::getModel('catalog/product')->getCollection();
$products->addAttributeToFilter('attribute_set_id',$attributeSetId);
$products->addAttributeToSelect('*');
$products->load();
foreach($products as $val) {
$productsArray[] = $val->getData();
}
return $productsArray;
}
I came here from google so it might be relevant to others:
for yarn
you could use:
yarn --cwd /path/to/your/app run start
exec has memory limitation of buffer size of 512k. In this case it is better to use spawn. With spawn one has access to stdout of executed command at run time
var spawn = require('child_process').spawn;
var prc = spawn('java', ['-jar', '-Xmx512M', '-Dfile.encoding=utf8', 'script/importlistings.jar']);
//noinspection JSUnresolvedFunction
prc.stdout.setEncoding('utf8');
prc.stdout.on('data', function (data) {
var str = data.toString()
var lines = str.split(/(\r?\n)/g);
console.log(lines.join(""));
});
prc.on('close', function (code) {
console.log('process exit code ' + code);
});
You can use this code(Recommended)
MemoryStream objMS = new MemoryStream();
DataTable oDT = new DataTable();//Your DataTable which you want to convert
oDT.WriteXml(objMS);
objMS.Position = 0;
XPathDocument result = new XPathDocument(objMS);
This is another way but first ex. is recommended
StringWriter objSW = new StringWriter();
DataTable oDt = new DataTable();//Your DataTable which you want to convert
oDt.WriteXml(objSW);
string result = objSW.ToString();
$host
is a variable of the Core module.
$host
This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.
This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.
$http_host
is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER
(ref).
$http_HEADER
The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;
Summarizing:
$http_host
equals always the HTTP_HOST
request header.$host
equals $http_host
, lowercase and without the port number (if present), except when HTTP_HOST
is absent or is an empty value. In that case, $host
equals the value of the server_name
directive of the server which processed the request.Nothing special. Just as same as common Java Class Instance.
But those class are Synthetic proxy classes
created by java.lang.reflect.Proxy#newProxyInstance
Introduced in 1.3
http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection
It is a part of Java. so each JVM should support it.
In short : they are created using JVM ASM tech ( defining javabyte code at runtime )
something using same tech:
java.lang.reflect.Proxy#newProxyInstance
getProxyClass0
to obtain a `Class
`
ProxyGenerator.generateProxyClass
which return a byte[]define class
to load the generated $Proxy
Class (the classname you have seen)each method is build with same bytecode like
invocation handler
's invoke()
invocation handler
's invoke()
the class(bytecode) represent in form of byte[]
How to draw a class
Thinking your java codes are compiled into bytecodes, just do this at runtime

These examples seem a bit inefficient. Try this if you want to act upon the value:
<input id="cta" type="email" placeholder="Enter Email...">
<button onclick="return joinMailingList()">Join</button>
<script>
const joinMailingList = () => {
const email = document.querySelector('#cta').value
console.log(email)
}
</script>
You will encounter issue if you use this
keyword with fat arrow (=>
). If you need to do that, go old school:
<script>
function joinMailingList() {
const email = document.querySelector('#cta').value
console.log(email)
}
</script>
If you are working with password inputs, you should use type="password"
so it will display ****** while the user is typing, and it is also more semantic.
First Name: <input type="text" autocomplete="off" name="input1"/> <br/> Last Name: <input type="text" autocomplete="off" name="input2"/> <br/> <input type="submit" value="Submit" /> </form>
There is a setting in the IE options that controls whether it should open new links in an existing window or in a new window. I'm not sure if you can control it from the command line but maybe changing this option would be enough for you.
In IE7 it looks like the option is "Reuse windows for launching shortcuts (when tabbed browsing is disabled)".
You can use an open source and cross-platform option: inst2xsd from Apache's XMLBeans. I find it very useful and easy.
Just download, unzip and play (it requires Java).
When I need this kind of functionality in Java, I usually use the Observer pattern. It does imply an extra object, but I think it's a clean way to go, and is a widely understood pattern, which helps with code readability.
26 % 7 (you will get remainder)
26 / 7 (you will get divisor can be float value )
26 // 7 (you will get divisor only integer value) )
Just adding this clarification so that anyone who scrolls down this much can at least gets it right, since there are so many wrong answers upvoted.
Diansheng's answer and JakeJ's answer get it right.
A new answer posted by Shital Shah is an even better and more complete answer.
Yes, logit
as a mathematical function in statistics, but the logit
used in context of neural networks is different. Statistical logit
doesn't even make any sense here.
I couldn't find a formal definition anywhere, but logit
basically means:
The raw predictions which come out of the last layer of the neural network.
1. This is the very tensor on which you apply theargmax
function to get the predicted class.
2. This is the very tensor which you feed into thesoftmax
function to get the probabilities for the predicted classes.
Also, from a tutorial on official tensorflow website:
Logits Layer
The final layer in our neural network is the logits layer, which will return the raw values for our predictions. We create a dense layer with 10 neurons (one for each target class 0–9), with linear activation (the default):
logits = tf.layers.dense(inputs=dropout, units=10)
If you are still confused, the situation is like this:
raw_predictions = neural_net(input_layer)
predicted_class_index_by_raw = argmax(raw_predictions)
probabilities = softmax(raw_predictions)
predicted_class_index_by_prob = argmax(probabilities)
where, predicted_class_index_by_raw
and predicted_class_index_by_prob
will be equal.
Another name for raw_predictions
in the above code is logit
.
As for the why logit
... I have no idea. Sorry.
[Edit: See this answer for the historical motivations behind the term.]
Although, if you want to, you can apply statistical logit
to probabilities
that come out of the softmax
function.
If the probability of a certain class is p
,
Then the log-odds of that class is L = logit(p)
.
Also, the probability of that class can be recovered as p = sigmoid(L)
, using the sigmoid
function.
Not very useful to calculate log-odds though.
Run package declaration and body separately.
Yes. Which platform are you writing for? ASP.NET C#?
List<string> myList = new List<string>();
Session["var"] = myList;
Then, to retrieve:
myList = (List<string>)Session["var"];
You should define source code encoding, add this to the top of your script:
# -*- coding: utf-8 -*-
The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:
import sys
print sys.getdefaultencoding()
Also see:
You may want to look into to Simple Logging Facade for Java (SLF4J). It is a facade that wraps around Log4j that doesn't require an initial setup call like Log4j. It is also fairly easy to switch out Log4j for Slf4j as the API differences are minimal.
Do you have access to a PC with Windows 7, or a PC with the SDK already installed?
If so, the easiest solution is to copy the C:\Program Files\Microsoft SDKs\Windows\v7.1
folder from the Windows 7 machine to the Windows 8 machine.
Closures can be declared as typealias
as below
typealias Completion = (Bool, Any, Error) -> Void
If you want to use in your function anywhere in code; you can write like normal variable
func xyz(with param1: String, completion: Completion) {
}
next() and nextLine() methods are associated with Scanner and is used for getting String inputs. Their differences are...
next() can read the input only till the space. It can't read two words separated by space. Also, next() places the cursor in the same line after reading the input.
nextLine() reads input including space between the words (that is, it reads till the end of line \n). Once the input is read, nextLine() positions the cursor in the next line.
Read article :Difference between next() and nextLine()
Replace your while loop with :
while(r.hasNext()) {
scan = r.next();
System.out.println(scan);
if(scan.length()==0) {continue;}
//treatment
}
Using hasNext()
and next()
methods will resolve the issue.
Untested and unsure if this will work, but why not do a few if statements
before, to set variables for the switch statement
.
var small, big;
if(scrollLeft < 1000){
//add some token to the page
//call it small
}
switch (//reference token/) {
case (small):
//do stuff
break;
case (big):
//do stuff;
break;
}
Or even easier and without the need to create a filter: use PHP's mb_strimwidth
to truncate a string to a certain width (length). Just make sure you use one of the get_
syntaxes.
For example with the content:
<?php $content = get_the_content(); echo mb_strimwidth($content, 0, 400, '...');?>
This will cut the string at 400 characters and close it with ...
.
Just add a "read more"-link to the end by pointing to the permalink with get_permalink()
.
<a href="<?php the_permalink() ?>">Read more </a>
Of course you could also build the read more
in the first line. Than just replace '...'
with '<a href="' . get_permalink() . '">[Read more]</a>'
After having the same issue, I got confused with all the answers here and the comments over the repository of sass in github.
I just want to point out that as December 2014, this issue has been resolved. It is now possible to import css
files directly into your sass file. The following PR in github solves the issue.
The syntax is the same as now - @import "your/path/to/the/file"
, without an extension after the file name. This will import your file directly. If you append *.css
at the end, it will translate into the css
rule @import url(...)
.
In case you are using some of the "fancy" new module bundlers such as webpack, you will probably need to use use ~
in the beginning of the path. So, if you want to import the following path node_modules/bootstrap/src/core.scss
you would write something like @import "~bootstrap/src/core"
.
NOTE:
It appears this isn't working for everybody. If your interpreter is based on libsass
it should be working fine (checkout this). I've tested using @import
on node-sass and it's working fine. Unfortunately this works and doesn't work on some ruby instances.

Make both divs like this. This will align both divs side-by-side.

display : inline-flex;
}
The order the bound callbacks are called in is managed by each jQuery object's event data. There aren't any functions (that I know of) that allow you to view and manipulate that data directly, you can only use bind() and unbind() (or any of the equivalent helper functions).
Dowski's method is best, you should modify the various bound callbacks to bind to an ordered sequence of custom events, with the "first" callback bound to the "real" event. That way, no matter in what order they are bound, the sequence will execute in the right way.
The only alternative I can see is something you really, really don't want to contemplate: if you know the binding syntax of the functions may have been bound before you, attempt to un-bind all of those functions and then re-bind them in the proper order yourself. That's just asking for trouble, because now you have duplicated code.
It would be cool if jQuery allowed you to simply change the order of the bound events in an object's event data, but without writing some code to hook into the jQuery core that doesn't seem possible. And there are probably implications of allowing this that I haven't thought of, so maybe it's an intentional omission.
You can do it with a dynamic query.
declare @cadena varchar(max) = ''
select @cadena = @cadena + 'exec spAPI ' + ltrim(id) + ';'
from sysobjects;
exec(@cadena);
I think the only way to get the tasks that are waiting is to keep a list of tasks you started and let the task remove itself from the list when it's started.
With rabbitmqctl and list_queues you can get an overview of how many tasks are waiting, but not the tasks itself: http://www.rabbitmq.com/man/rabbitmqctl.1.man.html
If what you want includes the task being processed, but are not finished yet, you can keep a list of you tasks and check their states:
from tasks import add
result = add.delay(4, 4)
result.ready() # True if finished
Or you let Celery store the results with CELERY_RESULT_BACKEND and check which of your tasks are not in there.
Assuming the following:
You can delete an Android Studio module as follows:
Use lang attribut on the input. Locale on my web app fr_FR, lang="en_EN" on the input number and i can use indifferently a comma or a dot. Firefox always display a dot, Chrome display a comma. But both separtor are valid.
Agree with Subir Kumar Sao and Faiz.

For Python3:
a, b = list(map(str, input().split()))
v = int(b)
Completely relative:
<img src="kitten.png"/>
this is a relative path indeed.
Absolute in all respects:
<img src="http://www.foo.com/images/kitten.png"/>
this is a URL, and it can be seen in some way as an absolute path, but it's not representative for this matter.
The difference between relative and absolute paths is that when using relative paths you take as reference the current working directory while with absolute paths you refer to a certain, well known directory. Relative paths are useful when you make some program that has to use resources from certain folders that can be opened using the working directory as a starting point.
Example of relative paths:
image.png
, which is the equivalent to .\image.png
(in Windows)
or ./image.png
(anywhere else).
The .
explicitly specifies that you're expressing a path
relative to the current working directory,
but this is implied whenever the path doesn't begin at a root directory
(designated with a slash), so you don't have to use it necessarily
(except in certain contexts where a default directory
(or a list of directories to search)
will be applied unless you explicitly specify some directory).
..\images\image2.jpg
This way you can access resources from directories one step up the folders tree. The ..\
means you've exited the current folder,
entering the directory that contains both the working and images
folders.
Again, use \
in Windows and /
anywhere else.
Example of absolute paths:
D:\documents\something.doc
E:\music\good_music.mp3
and so on.
Never, never, never say
if something == True:
Never. It's crazy, since you're redundantly repeating what is redundantly specified as the redundant condition rule for an if-statement.
Worse, still, never, never, never say
if something == False:
You have not
. Feel free to use it.
Finally, doing a == None
is inefficient. Do a is None
. None
is a special singleton object, there can only be one. Just check to see if you have that object.
Got the same error, CHECK THIS : MINOR SILLY MISTAKE
check findviewbyid(R.id.yourID); If you have put the id correct or not.
Yes, remove the trailing /
and (at least in ubuntu 11.04) all the paths given must be relative or full path. You can't mix absolute and relative paths in the same command.
sudo tar -czvf 2011.10.24.tar.gz ./start-directory --exclude "home/user/start-directory/logs"

will work
In Windows PC Follow below.

Edit the .env file
Edit the Highlighted and change the UserName and the password adn The database Name accordingly.
You're not including the C file that contains main()

As Jeppe Stig Nielsen said, this thread already has great answers, but I thought this rather obvious subtlety was worth mentioning too.
using
directives specified inside namespaces can make for shorter code since they don't need to be fully qualified as when they're specified on the outside.
The following example works because the types Foo
and Bar
are both in the same global namespace, Outer
.
Presume the code file Foo.cs:
namespace Outer.Inner
{
class Foo { }
}
And Bar.cs:
namespace Outer
{
using Outer.Inner;
class Bar
{
public Foo foo;
}
}
That may omit the outer namespace in the using
directive, for short:
namespace Outer
{
using Inner;
class Bar
{
public Foo foo;
}
}
If you change your property to use a backing field (instead of an automatic property), you can do the following:
public event EventHandler ImageFullPath1Changed;
private string _imageFullPath1 = string.Empty;
public string ImageFullPath1
{
get
{
return imageFullPath1 ;
}
set
{
if (_imageFullPath1 != value)
{
_imageFullPath1 = value;
EventHandler handler = ImageFullPathChanged;
if (handler != null)
handler(this, e);
}
}
}
Also make sure you have the PostgreSQL development package installed. On Ubuntu you need to do something like this:
$ sudo apt-get install libpq-dev
In Java 8 this can be made a little cleaner, assuming you have a static import for org.mockito.Mockito.doAnswer
:
doAnswer(i -> {
// Do stuff with i.getArguments() here
return null;
}).when(*mock*).*method*(*methodArguments*);
The return null;
is important and without it the compile will fail with some fairly obscure errors as it won't be able to find a suitable override for doAnswer
.
For example an ExecutorService
that just immediately executes any Runnable
passed to execute()
could be implemented using:
doAnswer(i -> {
((Runnable) i.getArguments()[0]).run();
return null;
}).when(executor).execute(any());
(I'm using React Native; targetSdkVersion 22). I'm trying to change the look of a calendar date picker dialog. The accepted answer didn't work for me, but this did. Hope this snippet helps some of you.

<item name="android:textColorPrimary">#6bf442</item>

Do you want to match a class exactly, e.g. only matching FileInputStream
instead of any subclass of FileInputStream
? If so, use getClass()
and ==
. I would typically do this in an equals
, so that an instance of X isn't deemed equal to an instance of a subclass of X - otherwise you can get into tricky symmetry problems. On the other hand, that's more usually useful for comparing that two objects are of the same class than of one specific class.
Otherwise, use instanceof
. Note that with getClass()
you will need to ensure you have a non-null reference to start with, or you'll get a NullPointerException
, whereas instanceof
will just return false
if the first operand is null.
Personally I'd say instanceof
is more idiomatic - but using either of them extensively is a design smell in most cases.
This is what I found to be useful
global $base_root;
$base_root . request_uri();
Returns query strings and it's what's used in core: page_set_cache()
For the CTRL+C case, you can use this:
// Tell the system console to handle CTRL+C by calling our method that
// gracefully shuts down.
Console.CancelKeyPress += new ConsoleCancelEventHandler(Console_CancelKeyPress);
static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
{
Console.WriteLine("Shutting down...");
// Cleanup here
System.Threading.Thread.Sleep(750);
}
I had the same problem while trying to read the data from the request body. In my case which occurs randomly only to the mobile-based client devices. So I have increased the connectionUploadTimeout
to 1min as suggested by this link
Adding the below code helped me overcome the issue.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11;
$res = ActivityServer::query()->select('channel_id')->where(['id' => $id])->first()->attributesToArray();
I use get()
, it returns an object, I use the attributesToArray()
to change the object attribute to an array.
Java jar files are the same format as zip files - so if you have a zip file utility that would let you modify an archive, you have your foot in the door. Second problem is, if you want to recompile a class or something, you probably will just have to re-build the jar; but a text file or something (xml, for instance) should be easily enough modified.
Be aware of that only 32 bit version of PHP is available on the Windows platform.
Then if you for instance shift << or >> more than by 31 bits, results are unexpectable. Usually the original number instead of zeros will be returned, and it can be a really tricky bug.
Of course if you use 64 bit version of PHP (Unix), you should avoid shifting by more than 63 bits. However, for instance, MySQL uses the 64-bit BIGINT, so there should not be any compatibility problems.
UPDATE: From PHP 7 Windows, PHP builds are finally able to use full 64 bit integers: The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). 64-bit platforms usually have a maximum value of about 9E18, except on Windows prior to PHP 7, where it was always 32 bit.
It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.
However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:
http://api.jquery.com/jQuery.post/
And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!
File uploading (most of this applies if sending plain text too if javascript can choose the name of the file) http://www.developershome.com/wap/wapUpload/wap_upload.asp?page=security https://www.owasp.org/index.php/Unrestricted_File_Upload
Was playing with this today... I beleive you can also use @@ROWCOUNT, like this:
DECLARE @SQL VARCHAR(50)
DECLARE @Rowcount INT
SET @SQL = 'SELECT 1 UNION SELECT 2'
EXEC(@SQL)
SET @Rowcount = @@ROWCOUNT
SELECT @Rowcount
Then replace the 'SELECT 1 UNION SELECT 2' with your actual select without the count. I'd suggest just putting 1 in your select, like this:
SELECT 1
FROM dbo.Comm_Services
WHERE....
....
(as opposed to putting SELECT *)
Hope that helps.
You can achieve with following way
this.projectService.create(project)
.subscribe(
result => {
console.log(result);
},
error => {
console.log(error);
this.errors = error
}
);
}
if (!this.errors) {
//route to new page
}
Thanks @Kit Ho for your answer. I used your code and found that I kept running into errors where my InputStream was always null and ClassNotFound exceptions when the JSONObject was being created. Here's my version of your code which does the trick for me:
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import org.apache.commons.io.IOUtils;
import org.json.JSONObject;
public class JSONParsing {
public static void main(String[] args) throws Exception {
File f = new File("file.json");
if (f.exists()){
InputStream is = new FileInputStream("file.json");
String jsonTxt = IOUtils.toString(is, "UTF-8");
System.out.println(jsonTxt);
JSONObject json = new JSONObject(jsonTxt);
String a = json.getString("1000");
System.out.println(a);
}
}
}
I found this answer to be enlightening about the difference between FileInputStream and getResourceAsStream. Hope this helps someone else too.

I liked the solution from Ruidge, but I needed more control from XML. So I changed it to Kotlin and added attributes.
1) Copy the Kotlin class:

constructor(context: Context, attributeSet: AttributeSet) : this(context, attributeSet, 0)

constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int) : super(
context,
attrs,
defStyleAttr
) {
val typedArray = context.obtainStyledAttributes(
attrs,
R.styleable.DashedDividerView,
defStyleAttr,
R.style.DashedDividerDefault
)
dGap = typedArray.getDimension(R.styleable.DashedDividerView_dividerDashGap, dGap)
dWidth = typedArray.getDimension(R.styleable.DashedDividerView_dividerDashWidth, dWidth)
dColor = typedArray.getColor(R.styleable.DashedDividerView_dividerDashColor, dColor)
direction =
typedArray.getInt(R.styleable.DashedDividerView_dividerDirection, DIRECTION_HORIZONTAL)
paint.color = dColor
paint.style = Paint.Style.STROKE
paint.pathEffect = DashPathEffect(floatArrayOf(dWidth, dGap), 0f)
paint.strokeWidth = dWidth
typedArray.recycle()

override fun onDraw(canvas: Canvas) {
super.onDraw(canvas)
path.moveTo(0f, 0f)
if (direction == DIRECTION_HORIZONTAL) {
path.lineTo(measuredWidth.toFloat(), 0f)
} else {
path.lineTo(0f, measuredHeight.toFloat())
}
canvas.drawPath(path, paint)
}
}
2) Create an attr file in the /res directory and add this
<declare-styleable name="DashedDividerView">
<attr name="dividerDashGap" format="dimension" />
<attr name="dividerDashWidth" format="dimension" />
<attr name="dividerDashColor" format="reference|color" />
<attr name="dividerDirection" format="enum">
<enum name="vertical" value="0" />
<enum name="horizontal" value="1" />
</attr>
</declare-styleable>
3) Add a style to the styles file
<style name="DashedDividerDefault">
<item name="dividerDashGap">2dp</item>
<item name="dividerDashWidth">2dp</item>
<!-- or any color -->
<item name="dividerDashColor">#EE0606</item>
<item name="dividerDirection">horizontal</item>
</style>
4) Now you can use the default style
<!-- here will be your path to the class -->
<com.your.package.app.DashedDividerView
android:layout_width="match_parent"
android:layout_height="2dp"
/>
or set attributes in XML
<com.your.package.app.DashedDividerView
android:layout_width="match_parent"
android:layout_height="2dp"
app:dividerDirection="horizontal"
app:dividerDashGap="2dp"
app:dividerDashWidth="2dp"
app:dividerDashColor="@color/light_gray"/>
I cribbed this and added the 'px'; Works very well.
function getOffset(el) {
el = el.getBoundingClientRect();
return {
left: (el.right + window.scrollX ) +'px',
top: (el.top + window.scrollY ) +'px'
}
}
to call: //Gets it to the right side
el.style.top = getOffset(othis).top ;
el.style.left = getOffset(othis).left ;
In PySpark(python) one of the option is to have the column in unix_timestamp format.We can convert string to unix_timestamp and specify the format as shown below. Note we need to import unix_timestamp and lit function
from pyspark.sql.functions import unix_timestamp, lit
df.withColumn("tx_date", to_date(unix_timestamp(df_cast["date"], "MM/dd/yyyy").cast("timestamp")))
Now we can apply the filters
df_cast.filter(df_cast["tx_date"] >= lit('2017-01-01')) \
.filter(df_cast["tx_date"] <= lit('2017-01-31')).show()
When one gets the error 'sub-query returns more than 1 row', the database is actually telling you that there is an unresolvable circular reference. It's a bit like using a spreadsheet and saying cell A1 = B1 and then saying B1 = A1. This error is typically associated with a scenario where one needs to have a double nested sub-query. I would recommend you look up a thing called a 'cross-tab query' this is the type of query one normally needs to solve this problem. It's basically an outer join (left or right) nested inside a sub-query or visa versa. One can also solve this problem with a double join (also considered to be a type of cross-tab query) such as below:
CREATE DEFINER=`root`@`localhost` PROCEDURE `SP_GET_VEHICLES_IN`(
IN P_email VARCHAR(150),
IN P_credentials VARCHAR(150)
)
BEGIN
DECLARE V_user_id INT(11);
SET V_user_id = (SELECT user_id FROM users WHERE email = P_email AND credentials = P_credentials LIMIT 1);
SELECT vehicles_in.vehicle_id, vehicles_in.make_id, vehicles_in.model_id, vehicles_in.model_year,
vehicles_in.registration, vehicles_in.date_taken, make.make_label, model.model_label
FROM make
LEFT OUTER JOIN vehicles_in ON vehicles_in.make_id = make.make_id
LEFT OUTER JOIN model ON model.make_id = make.make_id AND vehicles_in.model_id = model.model_id
WHERE vehicles_in.user_id = V_user_id;
END
In the code above notice that there are three tables in amongst the SELECT clause and these three tables show up after the FROM clause and after the two LEFT OUTER JOIN clauses, these three tables must be distinct amongst the FROM and LEFT OUTER JOIN clauses to be syntactically correct.
It is noteworthy that this is a very important construct to know as a developer especially if you're writing periodical report queries and it's probably the most important skill for any complex cross referencing, so all developers should study these constructs (cross-tab and double join).
Another thing I must warn about is: If you are going to use a cross-tab as a part of a working system and not just a periodical report, you must check the record count and reconfigure the join conditions until the minimum records are returned, otherwise large tables and cross-tabs can grind your server to a halt. Hope this helps.
You need to make use of the begin
and end
method of the vector
class, which return the iterator referring to the first and the last element respectively.
using namespace std;
vector<string> myvector; // a vector of stings.
// push some strings in the vector.
myvector.push_back("a");
myvector.push_back("b");
myvector.push_back("c");
myvector.push_back("d");
vector<string>::iterator it; // declare an iterator to a vector of strings
int n = 3; // nth element to be found.
int i = 0; // counter.
// now start at from the beginning
// and keep iterating over the element till you find
// nth element...or reach the end of vector.
for(it = myvector.begin(); it != myvector.end(); it++,i++ ) {
// found nth element..print and break.
if(i == n) {
cout<< *it << endl; // prints d.
break;
}
}
// other easier ways of doing the same.
// using operator[]
cout<<myvector[n]<<endl; // prints d.
// using the at method
cout << myvector.at(n) << endl; // prints d.
Short answer: Use the change
event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.
Using querySelector
.
var checkbox = document.querySelector("input[name=checkbox]");
checkbox.addEventListener('change', function() {
if (this.checked) {
console.log("Checkbox is checked..");
} else {
console.log("Checkbox is not checked..");
}
});
_x000D_
<input type="checkbox" name="checkbox" />
_x000D_
$('input[name=checkbox]').change(function() {
if ($(this).is(':checked')) {
console.log("Checkbox is checked..")
} else {
console.log("Checkbox is not checked..")
}
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" name="checkbox" />
_x000D_
Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll
instead of querySelector
. Then use Array.filter
and Array.map
to extract checked values.
// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []
/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/
// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
checkbox.addEventListener('change', function() {
enabledSettings =
Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
.filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
.map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
console.log(enabledSettings)
})
});
_x000D_
<label>
<input type="checkbox" name="settings" value="forcefield">
Enable forcefield
</label>
<label>
<input type="checkbox" name="settings" value="invisibilitycloak">
Enable invisibility cloak
</label>
<label>
<input type="checkbox" name="settings" value="warpspeed">
Enable warp speed
</label>
_x000D_
let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];
// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
enabledSettings = checkboxes
.filter(":checked") // Filter out unchecked boxes.
.map(function() { // Extract values using jQuery map.
return this.value;
})
.get() // Get array.
console.log(enabledSettings);
});

You could also use the coalesce function. I tested this in PostgreSQL, but it should also work for MySQL or MS SQL server.
INNER JOIN x ON coalesce(x.qid, -1) = coalesce(y.qid, -1)
This will replace NULL
with -1
before evaluating it. Hence there must be no -1
in qid
.

How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?
You can undo changes to tracked files with:
git reset HEAD --hard
You can remove untracked files with:
git clean -f
You can remove untracked files and directories with:
git clean -fd
but you can't undo change to untracked files.
You can remove ignored and untracked files and directories
git clean -fdx
but you can't undo change to ignored files.
You can also set clean.requireForce
to false
:
git config --global --add clean.requireForce false
to avoid using -f
(--force
) when you use git clean
.
There are many ways to create a train/test and even validation samples.
Case 1: classic way train_test_split
without any options:
from sklearn.model_selection import train_test_split
train, test = train_test_split(df, test_size=0.3)
Case 2: case of a very small datasets (<500 rows): in order to get results for all your lines with this cross-validation. At the end, you will have one prediction for each line of your available training set.
from sklearn.model_selection import KFold
kf = KFold(n_splits=10, random_state=0)
y_hat_all = []
for train_index, test_index in kf.split(X, y):
reg = RandomForestRegressor(n_estimators=50, random_state=0)
X_train, X_test = X[train_index], X[test_index]
y_train, y_test = y[train_index], y[test_index]
clf = reg.fit(X_train, y_train)
y_hat = clf.predict(X_test)
y_hat_all.append(y_hat)
Case 3a: Unbalanced datasets for classification purpose. Following the case 1, here is the equivalent solution:
from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X, y, stratify=y, test_size=0.3)
Case 3b: Unbalanced datasets for classification purpose. Following the case 2, here is the equivalent solution:
from sklearn.model_selection import StratifiedKFold
kf = StratifiedKFold(n_splits=10, random_state=0)
y_hat_all = []
for train_index, test_index in kf.split(X, y):
reg = RandomForestRegressor(n_estimators=50, random_state=0)
X_train, X_test = X[train_index], X[test_index]
y_train, y_test = y[train_index], y[test_index]
clf = reg.fit(X_train, y_train)
y_hat = clf.predict(X_test)
y_hat_all.append(y_hat)
Case 4: you need to create a train/test/validation sets on big data to tune hyperparameters (60% train, 20% test and 20% val).
from sklearn.model_selection import train_test_split
X_train, X_test_val, y_train, y_test_val = train_test_split(X, y, test_size=0.6)
X_test, X_val, y_test, y_val = train_test_split(X_test_val, y_test_val, stratify=y, test_size=0.5)
1) Declare menu
in your class.
private Menu menu;
2) In onCreateOptionsMenu
do the following :
public boolean onCreateOptionsMenu(Menu menu) {
this.menu = menu;
getMenuInflater().inflate(R.menu.menu_orders_screen, menu);
return true;
}
3) In onOptionsItemSelected
, get the item and do the changes as required(icon, text, colour, background)
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_search) {
return true;
}
if (id == R.id.ventor_status) {
return true;
}
if (id == R.id.action_settings_online) {
menu.getItem(0).setIcon(getResources().getDrawable(R.drawable.history_converted));
menu.getItem(1).setTitle("Online");
return true;
}
if (id == R.id.action_settings_offline) {
menu.getItem(0).setIcon(getResources().getDrawable(R.drawable.cross));
menu.getItem(1).setTitle("Offline");
return true;
}
return super.onOptionsItemSelected(item);
}
Note:
If you have 3 menu items :
menu.getItem(0) = 1 item,
menu.getItem(1) = 2 iteam,
menu.getItem(2) = 3 item
Based on this make the changes accordingly as per your requirement.
Do a cross-domain AJAX call
Your web-service must support method injection in order to do JSONP.
Your code seems fine and it should work if your web services and your web application hosted in the same domain.
When you do a $.ajax with dataType: 'jsonp' meaning that jQuery is actually adding a new parameter to the query URL.
For instance, if your URL is http://10.211.2.219:8080/SampleWebService/sample.do
then jQuery will add ?callback={some_random_dynamically_generated_method}.
This method is more kind of a proxy actually attached in window object. This is nothing specific but does look something like this:
window.some_random_dynamically_generated_method = function(actualJsonpData) {
//here actually has reference to the success function mentioned with $.ajax
//so it just calls the success method like this:
successCallback(actualJsonData);
}
Check the following for more information
There isn't a field initialization syntax like that for objects in JavaScript or TypeScript.
Option 1:
class bar {
// Makes a public field called 'length'
constructor(public length: number) { }
}
bars = [ new bar(1) ];
Option 2:
interface bar {
length: number;
}
bars = [ {length: 1} ];
The DATE_ADD() function will do the trick. (You can also use the ADDTIME() function if you're running at least v4.1.1.)
For your query, this would be:
SELECT *
FROM courses
WHERE DATE_ADD(now(), INTERVAL 2 HOUR) > start_time
Or,
SELECT *
FROM courses
WHERE ADDTIME(now(), '02:00:00') > start_time
Maybe good ol' cfront will do?
I wanted to get the selected label. This worked for me in jQuery 1.5.1.
$("#list :selected").text();
One difference is for r+
if the files does not exist, it'll not be created and open fails. But in case of a+
the file will be created if it does not exist.
An empty static class is appropriate. Consider using several classes, so that you end up with good groups of related constants, and not one giant Globals.cs file.
Additionally, for some int constants, consider the notation:
[Flags]
enum Foo
{
}
As this allows for treating the values like flags.
I know this question has an accepted answer, but I feel that it doesn't work in all cases.
For completeness and since I spent too much time on this, here is what we did: we ended up using a function from php.js (which is a pretty nice library for those more familiar with PHP but also doing a little JavaScript every now and then):
http://phpjs.org/functions/strip_tags:535
It seemed to be the only piece of JavaScript code which successfully dealt with all the different kinds of input I stuffed into my application. That is, without breaking it – see my comments about the <script />
tag above.
It means that the object you pass in the request (I guess it is pagedoc
) has a circular reference, something like:
var a = {};
a.b = a;
JSON.stringify
cannot convert structures like this.
N.B.: This would be the case with DOM nodes, which have circular references, even if they are not attached to the DOM tree. Each node has an ownerDocument
which refers to document
in most cases. document
has a reference to the DOM tree at least through document.body
and document.body.ownerDocument
refers back to document
again, which is only one of multiple circular references in the DOM tree.
There are some basics difference between ICollection and IEnumerable
Simple Program:
using System;
using System.Collections;
using System.Collections.Generic;
namespace StackDemo
{
class Program
{
static void Main(string[] args)
{
List<Person> persons = new List<Person>();
persons.Add(new Person("John",30));
persons.Add(new Person("Jack", 27));
ICollection<Person> personCollection = persons;
IEnumerable<Person> personEnumeration = persons;
// IEnumeration
// IEnumration Contains only GetEnumerator method to get Enumerator and make a looping
foreach (Person p in personEnumeration)
{
Console.WriteLine("Name:{0}, Age:{1}", p.Name, p.Age);
}
// ICollection
// ICollection Add/Remove/Contains/Count/CopyTo
// ICollection is inherited from IEnumerable
personCollection.Add(new Person("Tim", 10));
foreach (Person p in personCollection)
{
Console.WriteLine("Name:{0}, Age:{1}", p.Name, p.Age);
}
Console.ReadLine();
}
}
class Person
{
public string Name { get; set; }
public int Age { get; set; }
public Person(string name, int age)
{
this.Name = name;
this.Age = age;
}
}
}
Use a terminal-handling library like the curses module:
The curses module provides an interface to the curses library, the de-facto standard for portable advanced terminal handling.
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]);
}
As everyone has pointed out, you'll do this by setting a float:right;
on the RHS content and a negative margin on the LHS.
However.. if you don't use a float: left;
on the LHS (as Mohit does) then you'll get a stepping effect because the LHS div is still going to consume the margin'd space in layout.
However.. the LHS float will shrink-wrap the content, so you'll need to insert a defined width childnode if that's not acceptable, at which point you may as well have defined the width on the parent.
However.. as David points out you can change the read-order of the markup to avoid the LHS float requirement, but that's has readability and possibly accessibility issues.
However.. this problem can be solved with floats given some additional markup
(caveat: I don't approve of the .clearing div at that example, see here for details)
All things considered, I think most of us wish there was a non-greedy width:remaining in CSS3...
CSS selector:
Use a CSS selector of img[src='images/toolbar/b_edit.gif']
This says select element(s) with img
tag with attribute src
having value of 'images/toolbar/b_edit.gif'
CSS query:
VBA:
You can apply the selector with the .querySelector
method of document
.
IE.document.querySelector("img[src='images/toolbar/b_edit.gif']").Click
You should put the parameter gravity to bottom not in the textview but in the Linear Layout. Like this:
<LinearLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="bottom|end">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Something"/>
</LinearLayout>

Answer marked '905' looks good but does not work.
Following worked for me. Any Primary Key, Unique Key, or Default constraints CAN NOT be disabled. In fact, if 'sp_helpconstraint '' shows 'n/a' in status_enabled - Means it can NOT be enabled/disabled.
-- To generate script to DISABLE
select 'ALTER TABLE ' + object_name(id) + ' NOCHECK CONSTRAINT [' + object_name(constid) + ']'
from sys.sysconstraints
where status & 0x4813 = 0x813 order by object_name(id)
-- To generate script to ENABLE
select 'ALTER TABLE ' + object_name(id) + ' CHECK CONSTRAINT [' + object_name(constid) + ']'
from sys.sysconstraints
where status & 0x4813 = 0x813 order by object_name(id)
As of November 2017 Chrome Introduced a new css property

$char = chr(bindec($bin));
You can just create an object like this:
public class SomeQuery
{
public string SomeParameter { get; set; }
public int? SomeParameter2 { get; set; }
}
And then in controller just make something like that:
[HttpGet]
public IActionResult FindSomething([FromQuery] SomeQuery query)
{
// Your implementation goes here..
}
Even better, you can create API model from:
[HttpGet]
public IActionResult GetSomething([FromRoute] int someId, [FromQuery] SomeQuery query)
to:
[HttpGet]
public IActionResult GetSomething(ApiModel model)
public class ApiModel
{
[FromRoute]
public int SomeId { get; set; }
[FromQuery]
public string SomeParameter { get; set; }
[FromQuery]
public int? SomeParameter2 { get; set; }
}
Try this:
const scope = angular.element(document.getElementById('YourElementId')).scope();
scope.$apply(function(){
scope.myfunction('test');
});
Set the breakpoint
as you do normally, right click the break point and select condion
option and sets your condition.

If you have the script editor open you will see the logs under View->Logs. If your script has an onedit trigger, make a change to the spreadsheet which should trigger the function with the script editor opened in a second tab. Then go to the script editor tab and open the log. You will see whatever your function passes to the logger.
Basically as long as the script editor is open, the event will write to the log and show it for you. It will not show if someone else is in the file elsewhere.
Python allows for private class members with the double underscore prefix. This technique doesn't work at a module level so I am thinking this is a mistake in Dive Into Python.
Here is an example of private class functions:
class foo():
def bar(self): pass
def __bar(self): pass
f = foo()
f.bar() # this call succeeds
f.__bar() # this call fails
In the Old Days (pre-ANSI), predefining symbols such as unix
and vax
was a way to allow code to detect at compile time what system it was being compiled for. There was no official language standard back then (beyond the reference material at the back of the first edition of K&R), and C code of any complexity was typically a complex maze of #ifdef
s to allow for differences between systems. These macro definitions were generally set by the compiler itself, not defined in a library header file. Since there were no real rules about which identifiers could be used by the implementation and which were reserved for programmers, compiler writers felt free to use simple names like unix
and assumed that programmers would simply avoid using those names for their own purposes.
The 1989 ANSI C standard introduced rules restricting what symbols an implementation could legally predefine. A macro predefined by the compiler could only have a name starting with two underscores, or with an underscore followed by an uppercase letter, leaving programmers free to use identifiers not matching that pattern and not used in the standard library.
As a result, any compiler that predefines unix
or linux
is non-conforming, since it will fail to compile perfectly legal code that uses something like int linux = 5;
.
As it happens, gcc is non-conforming by default -- but it can be made to conform (reasonably well) with the right command-line options:
gcc -std=c90 -pedantic ... # or -std=c89 or -ansi
gcc -std=c99 -pedantic
gcc -std=c11 -pedantic
See the gcc manual for more details.
gcc will be phasing out these definitions in future releases, so you shouldn't write code that depends on them. If your program needs to know whether it's being compiled for a Linux target or not it can check whether __linux__
is defined (assuming you're using gcc or a compiler that's compatible with it). See the GNU C preprocessor manual for more information.
A largely irrelevant aside: the "Best One Liner" winner of the 1987 International Obfuscated C Code Contest, by David Korn (yes, the author of the Korn Shell) took advantage of the predefined unix
macro:
main() { printf(&unix["\021%six\012\0"],(unix)["have"]+"fun"-0x60);}
It prints "unix"
, but for reasons that have absolutely nothing to do with the spelling of the macro name.

I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.
I'm amazed by everyone else's MUCH more complicated answers.
You can very simply define the alpha in the color definition of the button (or any other view) in your xml:
android:color="#66FF0000" // Partially transparent red
In the above example, the color would be a partially transparent red.
When defining the color of a view, the format can be either #RRGGBB
or #AARRGGBB
, where AA
is the hex alpha value. FF
would be fully opaque and 00
would be full transparent.
If you need to dynamically alter the opacity in your code, use
myButton.getBackground().setAlpha(128); // 50% transparent
Where the INT ranges from 0
(fully transparent) to 255
(fully opaque).
I have encountered a similar error (*ngIf
) even if all my imports were OK and the component was rendered without any other error + routing was OK.
In my case AppModule
was not including that specific module. The strange thing is that it did not complain about this, but this might be related with how Ivy works with ng serve
(kind of loads modules according to routing, but its dependencies are not considered).
You are applying the formatting to the workbook that has the code, not the added workbook. You'll want to get in the habit of fully qualifying sheet and range references. The code below does that and works for me in Excel 2010:
Sub test()
Dim wb As Excel.Workbook
Set wb = Workbooks.Add
With wb.Sheets(1)
.Range("A1") = "Acctdate"
.Range("B1") = "Ledger"
.Range("C1") = "CY"
.Range("D1") = "BusinessUnit"
.Range("E1") = "OperatingUnit"
.Range("F1") = "LOB"
.Range("G1") = "Account"
.Range("H1") = "TreatyCode"
.Range("I1") = "Amount"
.Range("J1") = "TransactionCurrency"
.Range("K1") = "USDEquivalentAmount"
.Range("L1") = "KeyCol"
.Range("A2", "A50000").Value = Me.TextBox3.Value
.Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"
End With
End Sub
Actually, you do not need to do a first guess. Simply doing
import matplotlib.pyplot as plt
from scipy.optimize import curve_fit
from scipy import asarray as ar,exp
x = ar(range(10))
y = ar([0,1,2,3,4,5,4,3,2,1])
n = len(x) #the number of data
mean = sum(x*y)/n #note this correction
sigma = sum(y*(x-mean)**2)/n #note this correction
def gaus(x,a,x0,sigma):
return a*exp(-(x-x0)**2/(2*sigma**2))
popt,pcov = curve_fit(gaus,x,y)
#popt,pcov = curve_fit(gaus,x,y,p0=[1,mean,sigma])
plt.plot(x,y,'b+:',label='data')
plt.plot(x,gaus(x,*popt),'ro:',label='fit')
plt.legend()
plt.title('Fig. 3 - Fit for Time Constant')
plt.xlabel('Time (s)')
plt.ylabel('Voltage (V)')
plt.show()
works fine. This is simpler because making a guess is not trivial. I had more complex data and did not manage to do a proper first guess, but simply removing the first guess worked fine :)
P.S.: use numpy.exp() better, says a warning of scipy
More flexible.. Here's an example printing rows of right-justified numbers with fixed widths, and space-padding.
//---- Header
std::string getFmt ( int wid, long val )
{
char buf[64];
sprintf ( buf, "% *ld", wid, val );
return buf;
}
#define FMT (getFmt(8,x).c_str())
//---- Put to use
printf ( " COUNT USED FREE\n" );
printf ( "A: %s %s %s\n", FMT(C[0]), FMT(U[0]), FMT(F[0]) );
printf ( "B: %s %s %s\n", FMT(C[1]), FMT(U[1]), FMT(F[1]) );
printf ( "C: %s %s %s\n", FMT(C[2]), FMT(U[2]), FMT(F[2]) );
//-------- Output
COUNT USED FREE
A: 354 148523 3283
B: 54138259 12392759 200391
C: 91239 3281 61423

I was trying to solve my issue with some of the answers above and for some reason it didn't work. I did switch to use the git extensions and this are the steps I did follow.
Tools -> Settings -> SSH -> Other ssh client
C:\Program Files\Git\usr\bin\ssh.exe
I guess that this steps are just the same explained above. The only difference is that I used the Git Extensions User Interface instead of the terminal. Hope this help.
:active
denotes the interaction state (so for a button will be applied during press), :focus
may be a better choice here. However, the styling will be lost once another element gains focus.
The final potential alternative using CSS would be to use :target
, assuming the items being clicked are setting routes (e.g. anchors) within the page- however this can be interrupted if you are using routing (e.g. Angular), however this doesnt seem the case here.
.active:active {_x000D_
color: red;_x000D_
}_x000D_
.focus:focus {_x000D_
color: red;_x000D_
}_x000D_
:target {_x000D_
color: red;_x000D_
}
_x000D_
<button class='active'>Active</button>_x000D_
<button class='focus'>Focus</button>_x000D_
<a href='#target1' id='target1' class='target'>Target 1</a>_x000D_
<a href='#target2' id='target2' class='target'>Target 2</a>_x000D_
<a href='#target3' id='target3' class='target'>Target 3</a>
_x000D_
As such, there is no way in CSS to absolutely toggle a styled state- if none of the above work for you, you will either need to combine with a change in your HTML (e.g. based on a checkbox) or programatically apply/remove a class using e.g. jQuery
$('button').on('click', function(){_x000D_
$('button').removeClass('selected');_x000D_
$(this).addClass('selected');_x000D_
});
_x000D_
button.selected{_x000D_
color:red;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<button>Item</button><button>Item</button><button>Item</button>_x000D_

If it's a PHP issue, you could simply alter the configuration file php.ini wherever it's located and update the settings for PORT/SOCKET-PATH etc to make it connect to the server.
In my case, I opened the file php.ini and did
mysql.default_socket = /var/run/mysqld/mysqld.sock
mysqli.default_socket = /var/run/mysqld/mysqld.sock
And it worked straight away. I have to admit, I took hint from the accepted answer by @Joni
Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.
Copied from IIS Modules Overview: Preconditions
By calling it?
var path = System.Web.HttpContext.Current.Server.MapPath("default.aspx");
Make sure you add a reference to the System.Web assembly.
In a typical application there is a UITabBarController and it embeds 3 or more UIViewController as its tabs. In such a case if you subclassed a UITabBarController as YourTabBarController then you can set the selected index simply by:
selectedIndex = 1 // Displays 2nd tab. The index starts from 0.
In case you are navigating to YourTabBarController from any other view, then in that view controller's prepare(for segue:) method you can do:
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destination.
// Pass the selected object to the new view controller.
if segue.identifier == "SegueToYourTabBarController" {
if let destVC = segue.destination as? YourTabBarController {
destVC.selectedIndex = 0
}
}
I am using this way of setting tab with Xcode 10 and Swift 4.2.
I solved this issue for myself, I found there's was two files of http-client with different version of other dependent jar files. So there may version were collapsing between libraries files so remove all old/previous libraries files and re-add are jar files from lib folder of this zip file:
That should work, you may need a space after the commas.
Also, the function you call afterwards must support an array of objects, and not just a singleton object.
InputStream is;
InputStreamReader r = new InputStreamReader(is);
BufferedReader br = new BufferedReader(r);
(Adding to previous answers (hope that helps someone):)
Age is simpler but in case of string and with ignoring case:
@fathers.any? { |father| father[:name].casecmp("john") == 0 }
should work for any case in start or anywhere in the string i.e. for "John"
, "john"
or "JoHn"
and so on.
@fathers.find { |father| father[:name].casecmp("john") == 0 }
@fathers.select { |father| father[:name].casecmp("john") == 0 }
I had the same problem. The only solution that worked for me was adding <property = "defaultEncoding" value = "UTF-8"> to multipartResoler in spring configurations file.
You could do:
svn revert -R .
This will not delete any new file not under version control. But you can easily write a shell script to do that like:
for file in `svn status|grep "^ *?"|sed -e 's/^ *? *//'`; do rm $file ; done
You are comparing two objects for equality. The snippet:
if (obj == this) { return true; }
is a quick test that can be read
"If the object I'm comparing myself to is me, return true"
. You usually see this happen in equals
methods so they can exit early and avoid other costly comparisons.
git fetch --all
git checkout origin/master -- <your_file_path>
git add <your_file_path>
git commit -m "<your_file_name> updated"
This is assuming you are pulling the file from origin/master.
Initializer block is just like any bits of code; it's not "attached" to any field/method preceding it. To assign values to fields, you have to explicitly use the field as the lhs of an assignment statement.
private int lineCount; {
try{
lineCount = LineCounter.countLines(sFileName);
/*^^^^^^^*/
}
catch(IOException ex){
System.out.println (ex.toString());
System.out.println("Could not find file " + sFileName);
}
}
Also, your countLines
can be made simpler:
public static int countLines(String filename) throws IOException {
LineNumberReader reader = new LineNumberReader(new FileReader(filename));
while (reader.readLine() != null) {}
reader.close();
return reader.getLineNumber();
}
Based on my test, it looks like you can getLineNumber()
after close()
.
what about
$(parentSelect).nextAll().fadeOut(200, function() {
$(this).remove();
}).one(function(){
myfunction();
});
dist = sqrt( (x2 - x1)**2 + (y2 - y1)**2 )
As others have pointed out, you can also use the equivalent built-in math.hypot()
:
dist = math.hypot(x2 - x1, y2 - y1)
Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.
I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:
seq 1 500000 | while read digit; do
touch $(printf "abigfilename%06d\n" $digit);
done
And we note:
$ getconf ARG_MAX
2097152
Note however I can do this:
$ echo * > /dev/null
But this fails:
$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long
I can run a for loop:
$ for f in *; do :; done
which is another shell builtin.
Careful reading of the documentation for ARG_MAX
states, Maximum length of argument to the exec functions. This means: Without calling exec
, there is no ARG_MAX
limitation. So it would explain why shell builtins are not restricted by ARG_MAX
.
And indeed, I can ls
my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX
is working as advertised: the exec is failing with more than ARG_MAX
characters on the argument list- including, it should be noted, the environment data.
this one allow you "inject" a piece of text to textbox, inject means: appends the text where cursor is.
function inyectarTexto(elemento,valor){
var elemento_dom=document.getElementsByName(elemento)[0];
if(document.selection){
elemento_dom.focus();
sel=document.selection.createRange();
sel.text=valor;
return;
}if(elemento_dom.selectionStart||elemento_dom.selectionStart=="0"){
var t_start=elemento_dom.selectionStart;
var t_end=elemento_dom.selectionEnd;
var val_start=elemento_dom.value.substring(0,t_start);
var val_end=elemento_dom.value.substring(t_end,elemento_dom.value.length);
elemento_dom.value=val_start+valor+val_end;
}else{
elemento_dom.value+=valor;
}
}
And you can use it like this:
<a href="javascript:void(0);" onclick="inyectarTexto('nametField','hello world');" >Say hello world to text</a>
Funny and have more sence when we have "Insert Tag into Text" functionality.
works in all browsers.
I had problems aligning the label to the input(s) elements so I transferred the label element inside the form-inline and form-group too...and it works..
<div class="form-group">
<div class="col-xs-10">
<div class="form-inline">
<div class="form-group">
<label for="birthday" class="col-xs-2 control-label">Birthday:</label>
</div>
<div class="form-group">
<input type="text" class="form-control" placeholder="year"/>
</div>
<div class="form-group">
<input type="text" class="form-control" placeholder="month"/>
</div>
<div class="form-group">
<input type="text" class="form-control" placeholder="day"/>
</div>
</div>
</div>
</div>
jQuery has a toggleClass function:
<button class="switch">Click me</button>
<div class="text-block collapsed pressed">some text</div>
<script>
$('.switch').on('click', function(e) {
$('.text-block').toggleClass("collapsed pressed"); //you can list several class names
e.preventDefault();
});
</script>
While none of the above solution worked for me (else than running the application with an other username),Renaming the application folder in %appdata% fixed the porblem for me. "C:\Users...\AppData\Roaming\Microsoft\MS Project"
I would only recommend using @ to suppress warnings when it's a straight forward operation (e.g. $prop = @($high/($width - $depth)); to skip division by zero warnings). However in most cases it's better to handle.
If you know that you want the values to the thousandths, place, it's
SELECT (num - FLOOR(num)) * 1000 FROM table...;
Mine was caused by a corrupt Maven repository.
I deleted everything under C:\Users\<me>\.m2\repository

Then did an Eclipse Maven Update, and it worked first time.
So it was simply spring-boot.jar

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.
Bootstrap requires a specific file structure to work. I see from your code you have this:
<link href="bootstrap.css" rel="stylesheet" media="screen">
Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.
But first, let me recommend you setup your folder structure like so:
/css <-- Bootstrap.css here
/fonts <-- Bootstrap fonts here
/img
/js <-- Bootstrap JavaScript here
index.html
If you notice, this is also how Bootstrap structures its files in its download ZIP.
You then include your Bootstrap file like so:
<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">
Depending on your server structure or what you're going for.
The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).
The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.
So, why do this?
Bootstrap.css has this specific line for Glyphfonts:
@font-face {
font-family: 'Glyphicons Halflings';
src: url('../fonts/glyphicons-halflings-regular.eot');
src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}
What you can see is that that Glyphfonts are loaded by going up one directory ../
and then looking for a folder called /fonts
and THEN loading the font file.
The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:
/fonts
Bootstrap.css
index.html
The CSS file is going one level deeper than looking for a /fonts
folder.
So, let's say the actual location of these files are:
C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html
The CSS file would technically be looking for a folder at:
C:\fonts
but your folder is actually in:
C:\www\fonts
So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.
When you get that fixed, your HTML should simply be:
<span class="glyphicon glyphicon-comment"></span>
Note, you need both classes. The first class glyphicon
sets up the basic styles while glyphicon-comment
sets the specific image.
If you ought to spare memory, read char by char and realloc each time. Performance will die, but you'll spare this 10 bytes.
Another good tradeoff is to read in a function (using a local variable) then copying. So the big buffer will be function scoped.
If you want to add a Series and use the Series' index as columns of the DataFrame, you only need to append the Series between brackets:
In [1]: import pandas as pd
In [2]: df = pd.DataFrame()
In [3]: row=pd.Series([1,2,3],["A","B","C"])
In [4]: row
Out[4]:
A 1
B 2
C 3
dtype: int64
In [5]: df.append([row],ignore_index=True)
Out[5]:
A B C
0 1 2 3
[1 rows x 3 columns]
Whitout the ignore_index=True
you don't get proper index.
Another easy option was to use [HeidiSQL client][1] for PostgreSQL
database.
How to go into the database tab where all the databases and tables are listed.
Click on any of the table/View which you wanted to see the DDL/create a statement of the particular table.
Now there this client do the following jobs for you for that table, on the right-hand side windows:
The first window would be for data of table
Second for your SQL Host information
Third for database-level information like which tables and what is the size
Forth which we are more concern about table/view information tab will have the create table statement readily available for you.
I can not show you in the snapshot as working with confidential data, Try it with yourself and let me know if any issues you guys found.
you can get a files modified date using vbscript too
Set objFS=CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
strFile= objArgs(0)
WScript.Echo objFS.GetFile(strFile).DateLastModified
save the above as mygetdate.vbs and on command line
c:\test> cscript //nologo mygetdate.vbs myfile
Code check:
This is offtopic here but the people over at CodeReview are more than happy to help you.
I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.
Lists:
As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List
.
Lists are very straightforward to use but take a look at the related documentation anyway.
A very simple example to keep multiple bikes in a list:
List<Motorbike> bikes = new List<Motorbike>();
bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });
And to iterate over the list you can use the foreach
statement:
foreach(var bike in bikes) {
Console.WriteLine(bike.make);
}
int v2= Int32.Parse(v1.ToString());
Late contribution but just came across something similar in Python datetime and pandas give different timestamps for the same date.
If you have timezone-aware datetime in pandas
, technically, tz_localize(None)
changes the POSIX timestamp (that is used internally) as if the local time from the timestamp was UTC. Local in this context means local in the specified timezone. Ex:
import pandas as pd
t = pd.date_range(start="2013-05-18 12:00:00", periods=2, freq='H', tz="US/Central")
# DatetimeIndex(['2013-05-18 12:00:00-05:00', '2013-05-18 13:00:00-05:00'], dtype='datetime64[ns, US/Central]', freq='H')
t_loc = t.tz_localize(None)
# DatetimeIndex(['2013-05-18 12:00:00', '2013-05-18 13:00:00'], dtype='datetime64[ns]', freq='H')
# offset in seconds according to timezone:
(t_loc.values-t.values)//1e9
# array([-18000, -18000], dtype='timedelta64[ns]')
Note that this will leave you with strange things during DST transitions, e.g.
t = pd.date_range(start="2020-03-08 01:00:00", periods=2, freq='H', tz="US/Central")
(t.values[1]-t.values[0])//1e9
# numpy.timedelta64(3600,'ns')
t_loc = t.tz_localize(None)
(t_loc.values[1]-t_loc.values[0])//1e9
# numpy.timedelta64(7200,'ns')
In contrast, tz_convert(None)
does not modify the internal timestamp, it just removes the tzinfo
.
t_utc = t.tz_convert(None)
(t_utc.values-t.values)//1e9
# array([0, 0], dtype='timedelta64[ns]')
My bottom line would be: stick with timezone-aware datetime if you can or only use t.tz_convert(None)
which doesn't modify the underlying POSIX timestamp. Just keep in mind that you're practically working with UTC then.

ArrayDeque
is probably the fastest object-based queue in the JDK; Trove has the TIntQueue
interface, but I don't know where its implementations live.
"The $.browser property is deprecated in jQuery 1.3, and its functionality may be moved to a team-supported plugin in a future release of jQuery."
There are a few possible ways to do this:
PYTHONPATH
to a colon-separated list of directories to search for imported modules.sys.path.append('/path/to/search')
to add the names of directories you want Python to search for imported modules. sys.path
is just the list of directories Python searches every time it gets asked to import a module, and you can alter it as needed (although I wouldn't recommend removing any of the standard directories!). Any directories you put in the environment variable PYTHONPATH
will be inserted into sys.path
when Python starts up.site.addsitedir
to add a directory to sys.path
. The difference between this and just plain appending is that when you use addsitedir
, it also looks for .pth
files within that directory and uses them to possibly add additional directories to sys.path
based on the contents of the files. See the documentation for more detail.Which one of these you want to use depends on your situation. Remember that when you distribute your project to other users, they typically install it in such a manner that the Python code files will be automatically detected by Python's importer (i.e. packages are usually installed in the site-packages
directory), so if you mess with sys.path
in your code, that may be unnecessary and might even have adverse effects when that code runs on another computer. For development, I would venture a guess that setting PYTHONPATH
is usually the best way to go.
However, when you're using something that just runs on your own computer (or when you have nonstandard setups, e.g. sometimes in web app frameworks), it's not entirely uncommon to do something like
import sys
from os.path import dirname
sys.path.append(dirname(__file__))
You can use a regular expression as below:
return string1.toLowerCase().replace(/^[a-zA-z]|\s(.)/ig, L => L.toUpperCase());
Can also be hidden from Storyboard (working on Xcode 10.1)
By adding runtime attribute: hidesShadow - Boolean - True
Yes, your secret key appears to be missing. Without it, you will not be able to decrypt the files.
Do you have the key backed up somewhere?
Re-creating the keys, whether you use the same passphrase or not, will not work. Each key pair is unique.
In each class that you need to inherit from, you can run a loop of each class that needs init'd upon initiation of the child class...an example that can copied might be better understood...
class Female_Grandparent:
def __init__(self):
self.grandma_name = 'Grandma'
class Male_Grandparent:
def __init__(self):
self.grandpa_name = 'Grandpa'
class Parent(Female_Grandparent, Male_Grandparent):
def __init__(self):
Female_Grandparent.__init__(self)
Male_Grandparent.__init__(self)
self.parent_name = 'Parent Class'
class Child(Parent):
def __init__(self):
Parent.__init__(self)
#---------------------------------------------------------------------------------------#
for cls in Parent.__bases__: # This block grabs the classes of the child
cls.__init__(self) # class (which is named 'Parent' in this case),
# and iterates through them, initiating each one.
# The result is that each parent, of each child,
# is automatically handled upon initiation of the
# dependent class. WOOT WOOT! :D
#---------------------------------------------------------------------------------------#
g = Female_Grandparent()
print g.grandma_name
p = Parent()
print p.grandma_name
child = Child()
print child.grandma_name
Navbars can utilize .navbar-toggler, .navbar-collapse, and .navbar-expand{-sm|-md|-lg|-xl} classes to change when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.
For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.
For example :
<nav class="navbar navbar-expand-lg"></nav>
Mobile menu is showing in large screen.

Try this:
public class MyVmBase : INotifyPropertyChanged

private ICommand _clickCommand;
public ICommand ClickCommand

{
return _clickCommand ?? (_clickCommand = new CommandHandler( MyAction));
}
}
public void MyAction(object message)
{
if(message == null)
{
Notify($"Method {message} not defined");
return;
}
switch (message.ToString())
{
case "btnAdd":
{
btnAdd_Click();
break;
}
case "BtnEdit_Click":
{
BtnEdit_Click();
break;
}
default:
throw new Exception($"Method {message} not defined");
break;
}
}
}
public class CommandHandler : ICommand
{
private Action<object> _action;
private Func<object, bool> _canExecute;
/// <summary>
/// Creates instance of the command handler
/// </summary>
/// <param name="action">Action to be executed by the command</param>
/// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
public CommandHandler(Action<object> action, Func<object, bool> canExecute)
{
if (action == null) throw new ArgumentNullException(nameof(action));
_action = action;
_canExecute = canExecute ?? (x => true);
}
public CommandHandler(Action<object> action) : this(action, null)
{
}
/// <summary>
/// Wires CanExecuteChanged event
/// </summary>
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
/// <summary>

public bool CanExecute(object parameter)
{
return _canExecute(parameter);
}
public void Execute(object parameter)
{
_action(parameter);
}
public void Refresh()
{
CommandManager.InvalidateRequerySuggested();
}
}
And in xaml:
<Button

Your code won't work because you haven't assigned anything to n
before you first use it. Try this:
def oracle():
n = None
while n != 'Correct':
# etc...
A more readable approach is to move the test until later and use a break
:
def oracle():
guess = 50
while True:
print 'Current number = {0}'.format(guess)
n = raw_input("lower, higher or stop?: ")
if n == 'stop':
break
# etc...
Also input
in Python 2.x reads a line of input and then evaluates it. You want to use raw_input
.
Note: In Python 3.x, raw_input
has been renamed to input
and the old input
method no longer exists.
I recommend using passthru
and handling the output buffer directly:
ob_start();
passthru('/usr/bin/python2.7 /srv/http/assets/py/switch.py arg1 arg2');
$output = ob_get_clean();
A simple find and replace for a single character would go something like:
s.replace(s.find("x"), 1, "y")
To do this for the whole string, the easy thing to do would be to loop until your s.find
starts returning npos
. I suppose you could also catch range_error
to exit the loop, but that's kinda ugly.
vector<vector> matrix(row, vector(col, 0));
This will initialize a 2D vector of rows=row and columns = col with all initial values as 0. No need to initialize and use resize.
Since the vector is initialized with size, you can use "[]" operator as in array to modify the vector.
matrix[x][y] = 2;
To do POST you'll need to have a form.
<form action="employee.action" method="post">
<input type="submit" value="Employee1" />
</form>
There are some ways to post data with hyperlinks, but you'll need some javascript, and a form.
Some tricks: Make a link use POST instead of GET and How do you post data with a link
Edit: to load response on a frame you can target your form to your frame:
<form action="employee.action" method="post" target="myFrame">
From the docs on angular.element
:
find()
- Limited to lookups by tag name
So if you're not using jQuery with Angular, but relying upon its jqlite implementation, you can't do elm.find('#someid')
.
You do have access to children()
, contents()
, and data()
implementations, so you can usually find a way around it.

I might be late to the party but I was trying to implement dynamic refs to my project the proper way and all the answer I have found until know aren't quiet satisfying to my liking, so I came up with a solution that I think is simple and uses the native and recommended way of react to create the ref.
sometimes you find that the way documentation is wrote assumes that you have a known amount of views and in most cases this number is unknown so you need a way to solve the problem in this case, create dynamic refs to the unknown number of views you need to show in the class
so the most simple solution i could think of and worked flawlessly was to do as follows
class YourClass extends component {
state={
foo:"bar",
dynamicViews:[],
myData:[] //get some data from the web
}
inputRef = React.createRef()
componentDidMount(){
this.createViews()
}
createViews = ()=>{
const trs=[]
for (let i = 1; i < this.state.myData.lenght; i++) {
let ref =`myrefRow ${i}`
this[ref]= React.createRef()
const row = (
<tr ref={this[ref]}>
<td>
`myRow ${i}`
</td>
</tr>
)
trs.push(row)
}
this.setState({dynamicViews:trs})
}
clickHandler = ()=>{
//const scrollToView = this.inputRef.current.value
//That to select the value of the inputbox bt for demostrate the //example
value=`myrefRow ${30}`
this[value].current.scrollIntoView({ behavior: "smooth", block: "start" });
}
render(){
return(
<div style={{display:"flex", flexDirection:"column"}}>
<Button onClick={this.clickHandler}> Search</Button>
<input ref={this.inputRef}/>
<table>
<tbody>
{this.state.dynamicViews}
<tbody>
<table>
</div>
)
}
}
export default YourClass
that way the scroll will go to whatever row you are looking for..
cheers and hope it helps others
Another way of looking at this is using POSIX ACLs, it needs to be supported by your file system, however you can have fine-grained tuning of all commands in linux the same way you have the same control on Windows (just without the nicer UI). link
Another thing to look into is PolicyKit.
You'll have to do quite a bit of googling to get everything working as this is definitely not a strength of Linux at the moment.
Step 1) Remove the semi-colon, it's an object you're creating...
a(this).next().css({
left : c,
transition : 'opacity 1s ease-in-out';
});
to
a(this).next().css({
left : c,
transition : 'opacity 1s ease-in-out'
});
Step 2) Vendor-prefixes... no browsers use transition
since it's the standard and this is an experimental feature even in the latest browsers:
a(this).next().css({
left : c,
WebkitTransition : 'opacity 1s ease-in-out',
MozTransition : 'opacity 1s ease-in-out',
MsTransition : 'opacity 1s ease-in-out',
OTransition : 'opacity 1s ease-in-out',
transition : 'opacity 1s ease-in-out'
});
Here is a demo: http://jsfiddle.net/83FsJ/
Step 3) Better vendor-prefixes... Instead of adding tons of unnecessary CSS to elements (that will just be ignored by the browser) you can use jQuery to decide what vendor-prefix to use:
$('a').on('click', function () {
var myTransition = ($.browser.webkit) ? '-webkit-transition' :
($.browser.mozilla) ? '-moz-transition' :
($.browser.msie) ? '-ms-transition' :
($.browser.opera) ? '-o-transition' : 'transition',
myCSSObj = { opacity : 1 };
myCSSObj[myTransition] = 'opacity 1s ease-in-out';
$(this).next().css(myCSSObj);
});?
Here is a demo: http://jsfiddle.net/83FsJ/1/
Also note that if you specify in your transition
declaration that the property to animate is opacity
, setting a left
property won't be animated.
if a device has an SD card, you use:
Environment.getExternalStorageState()
if you don't have an SD card, you use:
Environment.getDataDirectory()
if there is no SD card, you can create your own directory on the device locally.
//if there is no SD card, create new directory objects to make directory on device
if (Environment.getExternalStorageState() == null) {
//create new file directory object
directory = new File(Environment.getDataDirectory()
+ "/RobotiumTestLog/");
photoDirectory = new File(Environment.getDataDirectory()
+ "/Robotium-Screenshots/");
/*
* this checks to see if there are any previous test photo files
* if there are any photos, they are deleted for the sake of
* memory
*/
if (photoDirectory.exists()) {
File[] dirFiles = photoDirectory.listFiles();
if (dirFiles.length != 0) {
for (int ii = 0; ii <= dirFiles.length; ii++) {
dirFiles[ii].delete();
}
}
}
// if no directory exists, create new directory
if (!directory.exists()) {
directory.mkdir();
}
// if phone DOES have sd card
} else if (Environment.getExternalStorageState() != null) {
// search for directory on SD card
directory = new File(Environment.getExternalStorageDirectory()
+ "/RobotiumTestLog/");
photoDirectory = new File(
Environment.getExternalStorageDirectory()
+ "/Robotium-Screenshots/");
if (photoDirectory.exists()) {
File[] dirFiles = photoDirectory.listFiles();
if (dirFiles.length > 0) {
for (int ii = 0; ii < dirFiles.length; ii++) {
dirFiles[ii].delete();
}
dirFiles = null;
}
}
// if no directory exists, create new directory to store test
// results
if (!directory.exists()) {
directory.mkdir();
}
}// end of SD card checking
add permissions on your manifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Edit
A better way to do this is:
Create your own less file as a main less file ( like bootstrap.less ).
Import all bootstrap less files you need. (in this case, you just need to Import all responsive less files but responsive-1200px-min.less
)
If you need to modify anything in original bootstrap less file, you just need to write your own less to overwrite bootstrap's less code. (Just remember to put your less code/file after @import { /* bootstrap's less file */ };
).
Original
I have the same problem. This is how I fixed it.
Find the media query:
@media (max-width:1200px) ...
Remove it. (I mean the whole thing , not just @media (max-width:1200px)
)
Since the default width of Bootstrap is 940px, you don't need to do anything.
If you want to have your own max-width
, just modify the css rule in the media query that matches your desired width.
If your input file has a fixed amount of columns separated by commas and you know in which columns are the strings it might be best to use the function
textscan()
Note that you can specify a format where you read up to a maximum number of characters in the string or until a delimiter (comma) is found.
You can achieve you goal with below ways :-
long millis=System.currentTimeMillis();
java.sql.Date date=new java.sql.Date(millis);
or
// create a java calendar instance
Calendar calendar = Calendar.getInstance();
// get a java date (java.util.Date) from the Calendar instance.
// this java date will represent the current date, or "now".
java.util.Date currentDate = calendar.getTime();
// now, create a java.sql.Date from the java.util.Date
java.sql.Date date = new java.sql.Date(currentDate.getTime());
