Here's another way without using calc()
.
// 4 PER ROW
// 100 divided by 4 is 25. Let's use 21% for width, and the remainder 4% for left & right margins...
.child {
margin: 0 2% 0 2%;
width: 21%;
}
// 3 PER ROW
// 100 divided by 3 is 33.3333... Let's use 30% for width, and remaining 3.3333% for sides (hint: 3.3333 / 2 = 1.66666)
.child {
margin: 0 1.66666% 0 1.66666%;
width: 30%;
}
// and so on!
That's all there is to it. You can get fancy with the dimensions to get a more aesthetic sizes but this is the idea.
You can stash
(save the changes in temporary box) then, back to master
branch HEAD.
$ git add .
$ git stash
$ git checkout master
Jump Over Commits Back and Forth:
Go to a specific commit-sha
.
$ git checkout <commit-sha>
If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.
# checkout a new branch, add, commit, push
$ git checkout -b <branch-name>
$ git add .
$ git commit -m 'Commit message'
$ git push origin HEAD # push the current branch to remote
$ git checkout master # back to master branch now
If you have changes in the specific commit and don't want to keep the changes, you can do stash
or reset
then checkout to master
(or, any other branch).
# stash
$ git add -A
$ git stash
$ git checkout master
# reset
$ git reset --hard HEAD
$ git checkout master
After checking out a specific commit if you have no uncommitted change(s) then, just back to master
or other
branch.
$ git status # see the changes
$ git checkout master
# or, shortcut
$ git checkout - # back to the previous state
Here's an example that shows how to do sync & async.
import Foundation
class HttpDownloader {
class func loadFileSync(url: NSURL, completion:(path:String, error:NSError!) -> Void) {
let documentsUrl = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first as! NSURL
let destinationUrl = documentsUrl.URLByAppendingPathComponent(url.lastPathComponent!)
if NSFileManager().fileExistsAtPath(destinationUrl.path!) {
println("file already exists [\(destinationUrl.path!)]")
completion(path: destinationUrl.path!, error:nil)
} else if let dataFromURL = NSData(contentsOfURL: url){
if dataFromURL.writeToURL(destinationUrl, atomically: true) {
println("file saved [\(destinationUrl.path!)]")
completion(path: destinationUrl.path!, error:nil)
} else {
println("error saving file")
let error = NSError(domain:"Error saving file", code:1001, userInfo:nil)
completion(path: destinationUrl.path!, error:error)
}
} else {
let error = NSError(domain:"Error downloading file", code:1002, userInfo:nil)
completion(path: destinationUrl.path!, error:error)
}
}
class func loadFileAsync(url: NSURL, completion:(path:String, error:NSError!) -> Void) {

let destinationUrl = documentsUrl.URLByAppendingPathComponent(url.lastPathComponent!)
if NSFileManager().fileExistsAtPath(destinationUrl.path!) {

let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil)
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "GET"
let task = session.dataTaskWithRequest(request, completionHandler: { (data: NSData!, response: NSURLResponse!, error: NSError!) -> Void in
if (error == nil) {
if let response = response as? NSHTTPURLResponse {
println("response=\(response)")
if response.statusCode == 200 {
if data.writeToURL(destinationUrl, atomically: true) {
println("file saved [\(destinationUrl.path!)]")
completion(path: destinationUrl.path!, error:error)
} else {
println("error saving file")
let error = NSError(domain:"Error saving file", code:1001, userInfo:nil)
completion(path: destinationUrl.path!, error:error)
}
}
}
}
else {
println("Failure: \(error.localizedDescription)");
completion(path: destinationUrl.path!, error:error)
}
})
task.resume()
}
}
}
Here's how to use it in your code:
let url = NSURL(string: "http://www.mywebsite.com/myfile.pdf")
HttpDownloader.loadFileAsync(url, completion:{(path:String, error:NSError!) in
println("pdf downloaded to: \(path)")
})
Training Dataset: The sample of data used to fit the model.
Validation Dataset: The sample of data used to provide an unbiased evaluation of a model fit on the training dataset while tuning model hyperparameters. The evaluation becomes more biased as skill on the validation dataset is incorporated into the model configuration.
Test Dataset: The sample of data used to provide an unbiased evaluation of a final model fit on the training dataset.
You could use np.where. If cond
is a boolean array, and A
and B
are arrays, then
C = np.where(cond, A, B)
defines C to be equal to A
where cond
is True, and B
where cond
is False.
import numpy as np
import pandas as pd
a = [['10', '1.2', '4.2'], ['15', '70', '0.03'], ['8', '5', '0']]
df = pd.DataFrame(a, columns=['one', 'two', 'three'])
df['que'] = np.where((df['one'] >= df['two']) & (df['one'] <= df['three'])
, df['one'], np.nan)
yields
one two three que
0 10 1.2 4.2 10
1 15 70 0.03 NaN
2 8 5 0 NaN
If you have more than one condition, then you could use np.select instead.
For example, if you wish df['que']
to equal df['two']
when df['one'] < df['two']
, then
conditions = [
(df['one'] >= df['two']) & (df['one'] <= df['three']),
df['one'] < df['two']]
choices = [df['one'], df['two']]
df['que'] = np.select(conditions, choices, default=np.nan)
yields
one two three que
0 10 1.2 4.2 10
1 15 70 0.03 70
2 8 5 0 NaN
If we can assume that df['one'] >= df['two']
when df['one'] < df['two']
is
False, then the conditions and choices could be simplified to
conditions = [
df['one'] < df['two'],
df['one'] <= df['three']]
choices = [df['two'], df['one']]
(The assumption may not be true if df['one']
or df['two']
contain NaNs.)
Note that
a = [['10', '1.2', '4.2'], ['15', '70', '0.03'], ['8', '5', '0']]
df = pd.DataFrame(a, columns=['one', 'two', 'three'])
defines a DataFrame with string values. Since they look numeric, you might be better off converting those strings to floats:
df2 = df.astype(float)
This changes the results, however, since strings compare character-by-character, while floats are compared numerically.
In [61]: '10' <= '4.2'
Out[61]: True
In [62]: 10 <= 4.2
Out[62]: False
There's a I/O library available, but if it's available depends on your scripting host (assuming you've embedded lua somewhere). It's available, if you're using the command line version. The complete I/O model is most likely what you're looking for.
Shortened version of @AnttiHaapala:
json.dumps(dict_with_sets, default=lambda x: list(x) if isinstance(x, set) else x)
After searching, I got this clue: https://instructobit.com/tutorial/108/How-to-share-global-variables-between-files-in-Python
the key is: turn on the function to call the variabel that set to global if a function activated.
then import the variabel again from that file.
i give you the hard example so you can understood:
file chromy.py
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
def opennormal():
global driver
options = Options()
driver = webdriver.Chrome(chrome_options=options)
def gotourl(str):
url = str
driver.get(url)
file tester.py
from chromy import * #this command call all function in chromy.py, but the 'driver' variable in opennormal function is not exists yet. run: dir() to check what you call.
opennormal() #this command activate the driver variable to global, but remember, at the first import you not import it
#then do this, this is the key to solve:
from chromy import driver #run dir() to check what you call and compare with the first dir() result.
#because you already re-import the global that you need, you can use it now
url = 'https://www.google.com'
gotourl(url)
That's the way you call the global variable that you set in a function. cheers don't forget to give credit
Neither is better than the other, they do exactly the same thing. However, using .encode()
and .decode()
is the more common way to do it. It is also compatible with Python 2.
The line starting ALREADYEXISTS
uses ’
as the closing quote, it should be using '
. The open quote on the next line (where the error is reported) is seen as the closing quote, and this mix up is causing the error.
fibo = f.fibo
references the class itself. You probably wanted fibo = f.fibo()
(note the parentheses) to make an instance of the class, after which fibo.f()
should succeed correctly.
f.fibo.f()
fails because you are essentially calling f(self, a=0)
without supplying self
; self
is "bound" automatically when you have an instance of the class.
I'm using rather specified charset (ISO-8859-2) because not every mail system (for example: http://10minutemail.com) can read UTF-8 mails. If you need this:
function utf8_to_latin2($str)
{
return iconv ( 'utf-8', 'ISO-8859-2' , $str );
}
function my_mail($to,$s,$text,$form, $reply)
{
mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
"From: $form\r\n".
"Reply-To: $reply\r\n".
"X-Mailer: PHP/" . phpversion());
}
I have made another mailer function, because apple device could not read well the previous version.
function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
$s= "=?utf-8?b?".base64_encode($s)."?=";
$headers = "MIME-Version: 1.0\r\n";
$headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
$headers.= "Content-Type: text/plain;charset=utf-8\r\n";
$headers.= "Reply-To: $reply\r\n";
$headers.= "X-Mailer: PHP/" . phpversion();
mail($to, $s, $body, $headers);
}
Just to clear up... or sum up...
nchar
and nvarchar
can store Unicode characters.char
and varchar
cannot store Unicode characters.char
and nchar
are fixed-length which will reserve storage space for number of characters you specify even if you don't use up all that space.varchar
and nvarchar
are variable-length which will only use up spaces for the characters you store. It will not reserve storage like char
or nchar
.nchar
and nvarchar
will take up twice as much storage space, so it may be wise to use them only if you need Unicode support.
The reason for this is that you are trying to use an IntentService. Here is the line from the API Docs
The IntentService does the following:
Stops the service after all start requests have been handled, so you never have to call stopSelf().
Thus if you want your service to run indefinitely i suggest you extend the Service class instead. However this does not guarantee your service will run indefinitely. Your service will still have a chance of being killed by the kernel in a state of low memory if it is low priority.So you have two options:
1)Keep it running in the foreground by calling the startForeground()
method.
2)Restart the service if it gets killed.
Here is a part of the example from the docs where they talk about restarting the service after it is killed
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "service starting", Toast.LENGTH_SHORT).show();
// For each start request, send a message to start a job and deliver the
// start ID so we know which request we're stopping when we finish the job
Message msg = mServiceHandler.obtainMessage();
msg.arg1 = startId;
mServiceHandler.sendMessage(msg);
// If we get killed, after returning from here, restart
return START_STICKY;
}
OS: Ubuntu16.04
Reason: I deleted the client config file(~/.docker/config.json)
Solution:
ps -fC PROCESSNAME
ps and grep is a dangerous combination -- grep tries to match everything on each line (thus the all too common: grep -v grep hack). ps -C doesn't use grep, it uses the process table for an exact match. Thus, you'll get an accurate list with: ps -fC sh rather finding every process with sh somewhere on the line.
in MS SQL Server you can do:
SET DATEFORMAT ymd
year, month, day,
Try your code like this:
var app = express();
app.get('/test', function(req, res) {
res.sendFile('views/test.html', {root: __dirname })
});
Use res.sendFile instead of reading the file manually so express can handle setting the content-type properly for you.
You don't need the app.engine
line, as that is handled internally by express.
Another (and I think better) way to achieve this is to actually intercept the data. limitTo is okay but what if you're limiting to 10 when your array actually contains thousands?
When calling my service I simply did this:
TaskService.getTasks(function(data){
$scope.tasks = data.slice(0,10);
});
This limits what is sent to the view, so should be much better for performance than doing this on the front-end.
CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.
In HTML,
<div id="hideme">
<audio id="audioTag" controls>
<source src="/path/to/audio.mp3">
</audio>
</div>
with JS
<script type="text/javascript">
window.onload = function() {
var audioEl = document.getElementById("audioTag");
audioEl.load();
audioEl.play();
};
</script>
In CSS,
#hideme {display: none;}
Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:
openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp
This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).
A couple things I think you could try:
Put the literal value of the version in the child pom
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.2.3.RELEASE</version>
<scope>runtime</scope>
</dependency>
Clear your .m2 cache normally located C:\Users\user.m2\repository. I would say I do this pretty frequently when I'm working in maven. Especially before committing so that I can be more confident CI will run. You don't have to nuke the folder every time, sometimes just your project packages and the .cache folder are enough.
Add a relativePath tag to your parent pom declaration
<parent>
<groupId>com.mycompany.app</groupId>
<artifactId>my-app</artifactId>
<version>1</version>
<relativePath>../parent/pom.xml</relativePath>
</parent>
It looks like you have 8 total errors in your poms. I would try to get some basic compilation running before adding the parent pom and properties.
table-layout:fixed
will resolve the expanding cell problem, but will create a new one. IE by default will hide the overflow but Mozilla will render it outside the box.
Another solution would be to use: overflow:hidden;width:?px
<table style="table-layout:fixed; width:100px">
<tr>
<td style="overflow:hidden; width:50px;">fearofthedarkihaveaconstantfearofadark</td>
<td>
test
</td>
</tr>
</table>
I don't think there would be any significant performance difference between them, but I would prefer the 1st way.
If you have a Boolean
reference, Boolean.toString(boolean)
will throw NullPointerException
if your reference is null
. As the reference is unboxed to boolean
before being passed to the method.
While, String.valueOf()
method as the source code shows, does the explicit null
check:
public static String valueOf(Object obj) {
return (obj == null) ? "null" : obj.toString();
}
Just test this code:
Boolean b = null;
System.out.println(String.valueOf(b)); // Prints null
System.out.println(Boolean.toString(b)); // Throws NPE
For primitive boolean, there is no difference.
Swift: You need to add a subview with clip to bounds
var DateView = UIView(frame: CGRectMake(0, 0, view.frame.width, 100))
DateView.layer.borderWidth=1
DateView.clipsToBounds = true
var myDatepicker = UIDatePicker(frame:CGRectMake(0,-20,view.frame.width,162));
DateView.addSubview(myDatepicker);
self.view.addSubview(DateView)
This should add a clipped 100 height date picker in the top of the view controller.
My answer is based on the one provided by @x-yuri; but my scenario it's a little bit different. I wanted an image containing the script, not bind without needing to bind-mount it.

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.
This can not have a variable:
create function Func() returns table
as
return
select 10 as ColName
You have to do like this instead:
create function Func()
returns @T table(ColName int)
as
begin
declare @Var int
set @Var = 10
insert into @T(ColName) values (@Var)
return
end
The above works,(having an original document with mixed pages of 11' and 16' wide). However auto rotate needs to be off otherwise landscape pages are saved with page white top and bottom, so dont work in full screen view.
Solution is to re open the new PDF in acrobat and crop the first image (carefully to avoid white border), then select page range i.e. all, this then applies to all pages. job done !
An easy way to do it:
var data = '{"result":true,"count":1}';
var json = eval("[" +data+ "]")[0]; // ;)
.className::-webkit-scrollbar {
width: 10px;
background-color: rgba(0,0,0,0);

.className::-webkit-scrollbar-thumb {
background: rgba(255, 255, 255, 0.5);
border-radius: 5px;
}
gave me a nice mobile/osx like one.
Thought I would throw in a variation to the use of the os.path.splitext without the need to use array indexing.
The function always returns a (root, ext)
pair so it is safe to use:
root, ext = os.path.splitext(path)
Example:
>>> import os
>>> path = 'my_text_file.txt'
>>> root, ext = os.path.splitext(path)
>>> root
'my_text_file'
>>> ext
'.txt'
I think the previous answer is the best way to do it here is another simple way. just to print the sorted results.
String path="/tmp";
String[] dirListing = null;
File dir = new File(path);
dirListing = dir.list();
Arrays.sort(dirListing);
System.out.println(Arrays.deepToString(dirListing));
There is a much simpler solution for that.
Actually treating the items of JArray
as JObject
works.
Here is an example:
Let's say we have such array of JSON objects:
JArray jArray = JArray.Parse(@"[
{
""name"": ""Croke Park II"",
""url"": ""http://twitter.com/search?q=%22Croke+Park+II%22"",
""promoted_content"": null,
""query"": ""%22Croke+Park+II%22"",
""events"": null
},
{
""name"": ""Siptu"",
""url"": ""http://twitter.com/search?q=Siptu"",
""promoted_content"": null,
""query"": ""Siptu"",
""events"": null
}]");
To get access each item we just do the following:
foreach (JObject item in jArray)
{
string name = item.GetValue("name").ToString();
string url = item.GetValue("url").ToString();
// ...
}
Select t1.SongName
From tablename t1
left join tablename t2
on t1.SongName = t2.SongName
and t1.PersonName <> t2.PersonName
and t1.Status = 'Complete' -- my assumption that this is necessary
and t2.Status = 'Complete' -- my assumption that this is necessary
and t1.PersonName IN ('Holly', 'Ryan')
and t2.PersonName IN ('Holly', 'Ryan')
The actual walk through the directories works as you have coded it. If you replace the contents of the inner loop with a simple print
statement you can see that each file is found:
import os
rootdir = 'C:/Users/sid/Desktop/test'
for subdir, dirs, files in os.walk(rootdir):
for file in files:
print os.path.join(subdir, file)
If you still get errors when running the above, please provide the error message.
Updated for Python3
import os
rootdir = 'C:/Users/sid/Desktop/test'
for subdir, dirs, files in os.walk(rootdir):
for file in files:
print(os.path.join(subdir, file))
First, you have two variables of the same name i
. This calls for confusion.
Second, you should declare a variable called sum
, which is initially zero. Then, in a loop, you should add to it the numbers from 1 upto and including positiveInteger
. After that, you should output the sum
.
If you are using .Net 4.0 (or less):
class BetterWebClient : WebClient
{
private WebRequest _Request = null;
protected override WebRequest GetWebRequest(Uri address)
{
this._Request = base.GetWebRequest(address);
if (this._Request is HttpWebRequest)
{
((HttpWebRequest)this._Request).AllowAutoRedirect = false;
}
return this._Request;
}
public HttpStatusCode StatusCode()
{
HttpStatusCode result;
if (this._Request == null)
{
throw (new InvalidOperationException("Unable to retrieve the status
code, maybe you haven't made a request yet."));
}
HttpWebResponse response = base.GetWebResponse(this._Request)
as HttpWebResponse;
if (response != null)
{
result = response.StatusCode;
}
else
{
throw (new InvalidOperationException("Unable to retrieve the status
code, maybe you haven't made a request yet."));
}
return result;
}
}
If you are using .Net 4.5.X or newer, switch to HttpClient:
var response = await client.GetAsync("http://www.contoso.com/");
var statusCode = response.StatusCode;
Let's asume that show_images.php
is in folder images
and the site root is public_html
, so:
echo dirname(__DIR__); // prints '/home/public_html/'
echo dirname(__FILE__); // prints '/home/public_html/images'
If you are using Android Lollipop i.e. SDK 21, then:
CookieManager.getInstance().setAcceptCookie(true);
won't work. You need to use:
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
I ran into same issue and the above line worked as a charm.
nchar(YOURSTRING)
you may need to convert to a character vector first;
nchar(as.character(YOURSTRING))
It looks like you may have made a mistake as to where you are doing the copy of an Array. Have a look at my explanation below and a slight modification to the code which should work in helping you reset the data to its previous state.
In your example i can see the following taking place:
Am i right in thinking you don't want the 3rd point to happen in that order?
Would this be better:
Try this:
getGenericItems(selected: Item) {
this.itemService.getGenericItems(selected).subscribe(
result => {
// make a backup before you change the genericItems
this.backupData = this.genericItems.slice();
// now update genericItems with the results from your request
this.genericItems = result;
});
}
You can find the list of formats here (in the Double.ToString()-MSDN-Article) as comments in the example section.
There is delete
, delete_all
, destroy
, and destroy_all
.
The docs are: older docs and Rails 3.0.0 docs
delete
doesn't instantiate the objects, while destroy
does. In general, delete
is faster than destroy
.
to pass many options you can pass a object to a @Input decorator with custom data in a single line.
In the template
<li *ngFor = 'let opt of currentQuestion.options'
[selectable] = 'opt'
[myOptions] ="{first: opt.val1, second: opt.val2}" // these are your multiple parameters
(selectedOption) = 'onOptionSelection($event)' >
{{opt.option}}
</li>
so in Directive class
@Directive({
selector: '[selectable]'
})
export class SelectableDirective{
private el: HTMLElement;
@Input('selectable') option:any;
@Input('myOptions') data;
//do something with data.first
...
// do something with data.second
}
The correct way to copy a stream in Java is as follows:
int count;
byte[] buffer = new byte[8192]; // or 4096, or more
while ((count = in.read(buffer)) > 0)
{
out.write(buffer, 0, count);
}
Wish I had a dollar for every time I've posted that in a forum.
Prior to Android KitKat you have to root your device to install new certificates.
From Android KitKat (4.0) up to Nougat (7.0) it's possible and easy. I was able to install the Charles Web Debbuging Proxy cert on my un-rooted device and successfully sniff SSL traffic.
Extract from http://wiki.cacert.org/FAQ/ImportRootCert
Before Android version 4.0, with Android version Gingerbread & Froyo, there was a single read-only file ( /system/etc/security/cacerts.bks ) containing the trust store with all the CA ('system') certificates trusted by default on Android. Both system apps and all applications developed with the Android SDK use this. Use these instructions on installing CAcert certificates on Android Gingerbread, Froyo, ...
Starting from Android 4.0 (Android ICS/'Ice Cream Sandwich', Android 4.3 'Jelly Bean' & Android 4.4 'KitKat'), system trusted certificates are on the (read-only) system partition in the folder '/system/etc/security/' as individual files. However, users can now easily add their own 'user' certificates which will be stored in '/data/misc/keychain/certs-added'.
System-installed certificates can be managed on the Android device in the Settings -> Security -> Certificates -> 'System'-section, whereas the user trusted certificates are manged in the 'User'-section there. When using user trusted certificates, Android will force the user of the Android device to implement additional safety measures: the use of a PIN-code, a pattern-lock or a password to unlock the device are mandatory when user-supplied certificates are used.
Installing CAcert certificates as 'user trusted'-certificates is very easy. Installing new certificates as 'system trusted'-certificates requires more work (and requires root access), but it has the advantage of avoiding the Android lockscreen requirement.
From Android N onwards it gets a littler harder, see this extract from the Charles proxy website:
As of Android N, you need to add configuration to your app in order to have it trust the SSL certificates generated by Charles SSL Proxying. This means that you can only use SSL Proxying with apps that you control.
In order to configure your app to trust Charles, you need to add a Network Security Configuration File to your app. This file can override the system default, enabling your app to trust user installed CA certificates (e.g. the Charles Root Certificate). You can specify that this only applies in debug builds of your application, so that production builds use the default trust profile.
Add a file res/xml/network_security_config.xml to your app:
<network-security-config>
<debug-overrides>
<trust-anchors>
<!-- Trust user added CAs while debuggable only -->
<certificates src="user" />
</trust-anchors>
</debug-overrides>
</network-security-config>
Then add a reference to this file in your app's manifest, as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest>
<application android:networkSecurityConfig="@xml/network_security_config">
</application>
</manifest>
Try export PYTHONHOME=/usr/local
. Python should be installed in /usr/local
on OS X.
This answer has received a little more attention than I anticipated, I'll add a little bit more context.
Normally, Python looks for its libraries in the paths prefix/lib
and exec_prefix/lib
, where prefix
and exec_prefix
are configuration options. If the PYTHONHOME
environment variable is set, then the value of prefix
and exec_prefix
are inherited from it. If the PYTHONHOME
environment variable is not set, then prefix
and exec_prefix
default to /usr/local
(and I believe there are other ways to set prefix
/exec_prefix
as well, but I'm not totally familiar with them).
Normally, when you receive the error message Could not find platform independent libraries <prefix>
, the string <prefix>
would be replaced with the actual value of prefix
. However, if prefix
has an empty value, then you get the rather cryptic messages posted in the question. One way to get an empty prefix
would be to set PYTHONHOME
to an empty string. More info about PYTHONHOME
, prefix
, and exec_prefix
is available in the official docs.
Same question as @Dan - why not StringReader ?
If it has to be InputStreamReader, then:
String charset = ...; // your charset
byte[] bytes = string.getBytes(charset);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
InputStreamReader isr = new InputStreamReader(bais);
You have multiple oddities happening. The first has been edited in your post, but it had to do with the order that the methods were being called.
.format
returns a string. String does not have a subtract
method.
The second issue is that you are subtracting the day, but not actually saving that as a variable.
Your code, then, should look like:
var startdate = moment();
startdate = startdate.subtract(1, "days");
startdate = startdate.format("DD-MM-YYYY");
However, you can chain this together; this would look like:
var startdate = moment().subtract(1, "days").format("DD-MM-YYYY");
The difference is that we're setting startdate to the changes that you're doing on startdate, because moment is destructive.
If you are looking for Angular (v2+, currently version 8), try this answer or the official guide.
I have rewritten your JS fiddle here: http://jsfiddle.net/YGQT9/
<div ng-app="myApp">
<form name="saveTemplateData" action="#" ng-controller="FormCtrl" ng-submit="submitForm()">
First name: <br/><input type="text" name="form.firstname">
<br/><br/>
Email Address: <br/><input type="text" ng-model="form.emailaddress">
<br/><br/>
<textarea rows="3" cols="25">
Describe your reason for submitting this form ...
</textarea>
<br/>
<input type="radio" ng-model="form.gender" value="female" />Female
<input type="radio" ng-model="form.gender" value="male" />Male
<br/><br/>
<input type="checkbox" ng-model="form.member" value="true"/> Already a member
<input type="checkbox" ng-model="form.member" value="false"/> Not a member
<br/>
<input type="file" ng-model="form.file_profile" id="file_profile">
<br/>
<input type="file" ng-model="form.file_avatar" id="file_avatar">
<br/><br/>
<input type="submit">
</form>
</div>
Here I'm using lots of angular directives(ng-controller
, ng-model
, ng-submit
) where you were using basic html form submission.
Normally all alternatives to "The angular way" work, but form submission is intercepted and cancelled by Angular to allow you to manipulate the data before submission
BUT the JSFiddle won't work properly as it doesn't allow any type of ajax/http post/get so you will have to run it locally.
For general advice on angular form submission see the cookbook examples
UPDATE The cookbook is gone. Instead have a look at the 1.x guide for for form submission
The cookbook for angular has lots of sample code which will help as the docs aren't very user friendly.
Angularjs changes your entire web development process, don't try doing things the way you are used to with JQuery or regular html/js, but for everything you do take a look around for some sample code, as there is almost always an angular alternative.
This error message is very confusing. I just fixed the other 'warnings' in my project and I really had only one (simple one):
warning C4101: 'i': unreferenced local variable
After I commented this unused i
, and compiled it, the other error went away.
I did this inside the render() method:
render() {
const project = () => {
switch(this.projectName) {
case "one": return <ComponentA />;
case "two": return <ComponentB />;
case "three": return <ComponentC />;
case "four": return <ComponentD />;
default: return <h1>No project match</h1>
}
}
return (
<div>{ project() }</div>
)
}
I tried to keep the render() return clean, so I put my logic in a 'const' function right above. This way I can also indent my switch cases neatly.
background-position: calc(100% - 8px);
Update April 2013: Don't do this. It wasn't a good idea in 2009 when I first answered the question and it really isn't a good idea now. See this answer by hackbod for reasons:
Avoid reloading activity with asynctask on orientation change in android
Add android:configChanges="keyboardHidden|orientation"
to your AndroidManifest.xml. This tells the system what configuration changes you are going to handle yourself - in this case by doing nothing.
<activity android:name="MainActivity"
android:screenOrientation="portrait"
android:configChanges="keyboardHidden|orientation">
See Developer reference configChanges for more details.
However, your application can be interrupted at any time, e.g. by a phone call, so you really should add code to save the state of your application when it is paused.
Update: As of Android 3.2, you also need to add "screenSize":
<activity
android:name="MainActivity"
android:screenOrientation="portrait"
android:configChanges="keyboardHidden|orientation|screenSize">
From Developer guide Handling the Configuration Change Yourself
Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must declare
android:configChanges="orientation|screenSize"
. However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).
if you want it without try and except then there is the solution
what you are trying to do is print 'hello' if 'harry' in a list then the solution is
'hello' if 'harry' in sam else ''
Try this code :
import numpy as np
a1 = np.array([])
n = int(input(""))
for i in range(0,n):
a = int(input(""))
a1 = np.append(a, a1)
a = 0
print(a1)
Also you can use array instead of "a"
Remove these two lines:
xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");
XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.

I had this issue when after rebooted and the last copy of VSCode reopened. The above fix did not work, but when I closed and reopened VSCode via explorer it worked. Here are the steps I did:
//received fatal error_x000D_
git remote remove origin_x000D_
git init_x000D_
git remote add origin git@github:<yoursite>/<your project>.git_x000D_
// still received an err _x000D_
//restarted VSCode and folder via IE _x000D_
//updated one char and resaved the index.html _x000D_
git add ._x000D_
git commit -m "blah"_x000D_
git push origin master
_x000D_
If you really need True
or False
, just use bool
>>> bool(re.search("hi", "abcdefghijkl"))
True
>>> bool(re.search("hi", "abcdefgijkl"))
False
As other answers have pointed out, if you are just using it as a condition for an if
or while
, you can use it directly without wrapping in bool()
I understand that you want the Widget2 sharing the bottom border with the contents div. Try adding
style="position: relative; bottom: 0px"
to your Widget2 tag. Also try:
style="position: absolute; bottom: 0px"
if you want to snap your widget to the bottom of the screen.
I am a little rusty with CSS, perhaps the correct style is "margin-bottom: 0px" instead "bottom: 0px", give it a try. Also the pull-right class seems to add a "float=right" style to the element, and I am not sure how this behaves with "position: relative" and "position: absolute", I would remove it.
Each call to nextLine()
moves onto the next line, so when you are actually at the last readable line and the while
check passes inspection, the next call to nextLine()
will return EOF
.
Perhaps you could do one of the following instead:
If fileReader
is of type Scanner
:
while ((line = fileReader.hasNextLine()) != null) {
String line = fileReader.nextLine();
System.out.println(line);
}
If fileReader
is of type BufferedReader
:
String line;
while ((line = fileReader.readLine()) != null) {
System.out.println(line);
}
So you're reading the current line in the while condition and saving the line in a string for later use.
You can also use DBMS_METADATA:
select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY', 'PADCAMPAIGN')
from dual
import json
d = json.loads(j)
print d['glossary']['title']
Create your shell script as login.sh
in your $HOME folder.
Paste the following one-line script into Script Editor:
do shell script "$HOME/login.sh"
Then save it as an application.
Finally add the application to your login items.
If you want to make the script output visual, you can swap step 2 for this:
tell application "Terminal"
activate
do script "$HOME/login.sh"
end tell
If multiple commands are needed something like this can be used:
tell application "Terminal"
activate
do script "cd $HOME"
do script "./login.sh" in window 1
end tell
You can use menu left sidebar collapse accordion, animated with right arrow
Apache MPM prefork with modphp is used because it is easy to configure/install. Performance-wise it is fairly inefficient. My preferred way to do the stack, FastCGI/PHP-FPM. That way you can use the much faster MPM Worker. The whole PHP remains non-threaded, but Apache serves threaded (like it should).
So basically, from bottom to top
Linux
Apache + MPM Worker + ModFastCGI (NOT FCGI) |(or)| Cherokee |(or)| Nginx
PHP-FPM + APC
ModFCGI does not correctly support PHP-FPM, or any external FastCGI applications. It only supports non-process managed FastCGI scripts. PHP-FPM is the PHP FastCGI process manager.

Mathew's answer works for the terminal python shell, but it didn't work for IDLE shell in my case because many versions of python existed before I replaced them all with Python2.7.7. How I solved the problem with IDLE.
cd /Applications/Python\ 2.7/IDLE.app/Contents/Resources/
sudo nano idlemain.py
, enter password if required.os.chdir(os.path.expanduser('~/Documents'))
this line, I added sys.path.append("/Users/admin/Downloads....")
NOTE: replace contents of the quotes with the directory where python module to be addedThis seems to work, though possibly cumbersome for large lists.
>>> A = [0, 1]
>>> B = [1, 0]
>>> C = [0, 2]
>>> not sum([not i in A for i in B])
True
>>> not sum([not i in A for i in C])
False
>>>
However, if each list must contain all the elements of other then the above code is problematic.
>>> A = [0, 1, 2]
>>> not sum([not i in A for i in B])
True
The problem arises when len(A) != len(B)
and, in this example, len(A) > len(B)
. To avoid this, you can add one more statement.
>>> not sum([not i in A for i in B]) if len(A) == len(B) else False
False
One more thing, I benchmarked my solution with timeit.repeat, under the same conditions used by Aaron Hall in his post. As suspected, the results are disappointing. My method is the last one. set(x) == set(y)
it is.
>>> def foocomprehend(): return not sum([not i in data for i in data2])
>>> min(timeit.repeat('fooset()', 'from __main__ import fooset, foocount, foocomprehend'))
25.2893661496
>>> min(timeit.repeat('foosort()', 'from __main__ import fooset, foocount, foocomprehend'))

The "/f" is for "force". If you know the PID, then you can specify that, as in:

Lots of other options are possible, just type taskkill /? for all of them. The "/t" option kills a process and any child processes; that may be useful to you.

This is if you are building a package and you are finding error in imports. I learnt it the hard way.The answer isn't to add the package to python path or to do it programatically (what if your module gets installed and your command adds it again?) thats a bad way.
The right thing to do is: 1) Use virtualenv pyvenv-3.4 or something similar 2) Activate the development mode - $python setup.py develop

You may use clone()
which works well if your object has immutable objects and/or primitives, but it may be a little problematic when you don't have these ( such as collections ) for which you may need to perform a deep clone.
User userCopy = (User) user.clone();//make a copy
for(...) {
user.age = 1;
user.id = -1;
UserDao.update(user)
user = userCopy;
}
It seems like you just want to preserve the attributes: age
and id
which are of type int
so, why don't you give it a try and see if it works.
For more complex scenarios you could create a "copy" method:
publc class User {
public static User copy( User other ) {
User newUser = new User();
newUser.age = other.age;
newUser.id = other.id;
//... etc.
return newUser;
}
}
It should take you about 10 minutes.
And then you can use that instead:
User userCopy = User.copy( user ); //make a copy
// etc.
To read more about clone read this chapter in Joshua Bloch "Effective Java: Override clone judiciously"
Yes, jQuery
can be used with Node.js
.
Steps to include jQuery in node project:-
npm i jquery --save
Include jquery in codes
import jQuery from 'jquery';
const $ = jQuery;
I do use jquery in node.js projects all the time specifically in the chrome extension's project.
e.g. https://github.com/fxnoob/gesture-control-chrome-extension/blob/master/src/default_plugins/tab.js
As mentioned before, filesaver is a great package to work with files on the client side. But, it is not do well with large files. StreamSaver.js is an alternative solution (which is pointed in FileServer.js) that can handle large files:
const fileStream = streamSaver.createWriteStream('filename.txt', size);
const writer = fileStream.getWriter();
for(var i = 0; i < 100; i++){
var uint8array = new TextEncoder("utf-8").encode("Plain Text");
writer.write(uint8array);
}
writer.close()
You can grab eng.traineddata
Github:
wget https://github.com/tesseract-ocr/tessdata/raw/master/eng.traineddata
Check https://github.com/tesseract-ocr/tessdata for a full list of trained language data.
When you grab the file(s), move them to the /usr/local/share/tessdata
folder. Warning: some Linux distributions (such as openSUSE and Ubuntu) may be expecting it in /usr/share/tessdata
instead.
# If you got the data from Google, unzip it first!
gunzip eng.traineddata.gz
# Move the data
sudo mv -v eng.traineddata /usr/local/share/tessdata/
If all of the above does not work, you need to debug and make sure function onCreateOptionsMenu has been called (by placing debug or write log...)
If it's not run, maybe your Android theme is not supporting the action bar.
Open AndroidManifest.xml and set the value for android:theme
with theme support action bar:
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat">
In case the display is the only parameter from your style, you can run this command in order to remove all style:
$('#element').attr('style','');
Means that if your element looked like this before:
<input id="element" style="display: block;">
Now your element will look like this:
<input id="element" style="">
<?php
$field = 'display_name';
the_author_meta($field);
?>
Valid values for the $field
parameter include:
In the year of 2018, there's no need for listeners interfaces. You've got Android LiveData to take care of passing the desired result back to the UI components.
If I'll take Rupesh's answer and adjust it to use LiveData, it will like so:
public class Event {
public LiveData<EventResult> doEvent() {
/*
* code code code
*/
// and in the end
LiveData<EventResult> result = new MutableLiveData<>();
result.setValue(eventResult);
return result;
}
}
and now in your driver class MyTestDriver:
public class MyTestDriver {
public static void main(String[] args) {
Event e = new Event();
e.doEvent().observe(this, new Observer<EventResult>() {
@Override
public void onChanged(final EventResult er) {
// do your work.
}
});
}
}
For more information along with code samples you can read my post about it, as well as the offical docs:
Here's a solution to the general case that doesn't involve needing to know the length of the array ahead of time, using collect
, or using udf
s. Unfortunately this only works for spark
version 2.1 and above, because it requires the posexplode
function.
Suppose you had the following DataFrame:
df = spark.createDataFrame(
[
[1, 'A, B, C, D'],
[2, 'E, F, G'],
[3, 'H, I'],
[4, 'J']
]
, ["num", "letters"]
)
df.show()
#+---+----------+
#|num| letters|
#+---+----------+
#| 1|A, B, C, D|
#| 2| E, F, G|
#| 3| H, I|
#| 4| J|
#+---+----------+
Split the letters
column and then use posexplode
to explode the resultant array along with the position in the array. Next use pyspark.sql.functions.expr
to grab the element at index pos
in this array.
import pyspark.sql.functions as f
df.select(
"num",
f.split("letters", ", ").alias("letters"),
f.posexplode(f.split("letters", ", ")).alias("pos", "val")
)\
.show()
#+---+------------+---+---+
#|num| letters|pos|val|
#+---+------------+---+---+
#| 1|[A, B, C, D]| 0| A|
#| 1|[A, B, C, D]| 1| B|
#| 1|[A, B, C, D]| 2| C|
#| 1|[A, B, C, D]| 3| D|
#| 2| [E, F, G]| 0| E|
#| 2| [E, F, G]| 1| F|
#| 2| [E, F, G]| 2| G|
#| 3| [H, I]| 0| H|
#| 3| [H, I]| 1| I|
#| 4| [J]| 0| J|
#+---+------------+---+---+
Now we create two new columns from this result. First one is the name of our new column, which will be a concatenation of letter
and the index in the array. The second column will be the value at the corresponding index in the array. We get the latter by exploiting the functionality of pyspark.sql.functions.expr
which allows us use column values as parameters.
df.select(
"num",
f.split("letters", ", ").alias("letters"),
f.posexplode(f.split("letters", ", ")).alias("pos", "val")
)\
.drop("val")\
.select(
"num",
f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
f.expr("letters[pos]").alias("val")
)\
.show()
#+---+-------+---+
#|num| name|val|
#+---+-------+---+
#| 1|letter0| A|
#| 1|letter1| B|
#| 1|letter2| C|
#| 1|letter3| D|
#| 2|letter0| E|
#| 2|letter1| F|
#| 2|letter2| G|
#| 3|letter0| H|
#| 3|letter1| I|
#| 4|letter0| J|
#+---+-------+---+
Now we can just groupBy

Have just started switching over a project to c++11 and came across a perfectly good situation for constexpr which cleans up alternative methods of performing the same operation. The key point here is that you can only place the function into the array size declaration when it is declared constexpr. There are a number of situations where I can see this being very useful moving forward with the area of code that I am involved in.
constexpr size_t GetMaxIPV4StringLength()
{
return ( sizeof( "255.255.255.255" ) );
}
void SomeIPFunction()
{
char szIPAddress[ GetMaxIPV4StringLength() ];
SomeIPGetFunction( szIPAddress );
}

Joininig @Rudi's and @Pete's answers. I have created an RotateAnimation that keeps buttons functionality also after rotation.
setRotation() method preserves buttons functionality.
Code Sample:
Animation an = new RotateAnimation(0.0f, 180.0f, mainLayout.getWidth()/2, mainLayout.getHeight()/2);
an.setDuration(1000);
an.setRepeatCount(0);
an.setFillAfter(false); // DO NOT keep rotation after animation
an.setFillEnabled(true); // Make smooth ending of Animation
an.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {}
@Override
public void onAnimationRepeat(Animation animation) {}
@Override
public void onAnimationEnd(Animation animation) {
mainLayout.setRotation(180.0f); // Make instant rotation when Animation is finished
}
});
mainLayout.startAnimation(an);
mainLayout is a (LinearLayout) field
Just add the ? sign after index.php in the .htaccess file :
RewriteEngine on

You are using Ajax incorrectly. The idea is not to have it return anything, but instead hand off the data to something called a callback function, which handles the data.
That is:
function handleData( responseData ) {
// Do what you want with the data
console.log(responseData);
}
$.ajax({
url: "hi.php",
...
success: function ( data, status, XHR ) {
handleData(data);
}
});
Returning anything in the submit handler will not do anything. You must instead either hand off the data, or do what you want with it directly inside the success function.
target="_blank"
Opens a new window and show the related data.
target="_self"
Opens the window in the same frame, it means existing window itself.
target="_top"
Opens the linked document in the full body of the window.
target="_parent"
Opens data in the size of parent window.
myHash.each{|item|..}
is returning you array object for item
iterative variable like the following :--
[:company_name, "MyCompany"]
[:street, "Mainstreet"]
[:postcode, "1234"]
[:city, "MyCity"]
[:free_seats, "3"]
You should do this:--
def format
output = Hash.new
myHash.each do |k, v|
output[k] = cleanup(v)
end
output
end
You can get last N records simply by using last method:
Record.last(N)
Example:
User.last(5)
Returns 5 users in descending order by their id.
An active record query like this I think would get you what you want ('Something' is the model name):
Something.find(:all, :order => "id desc", :limit => 5).reverse
edit: As noted in the comments, another way:
result = Something.find(:all, :order => "id desc", :limit => 5)
while !result.empty?
puts result.pop
end

For t2/m3/c3/c4/r3/i2/d2 instances:
m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.
I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).
The large instance size has the most variation reported:
Burstable (T2) instances appear to exhibit burstable networking performance too:
The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:
t2.small (PDF)
Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.
You can use Array.filter function to filter out elements of an array based on the return value of a callback function. The callback function runs for every element of the original array.
The logic for the callback function here is that if the indexOf
value for current item is same as the index, it means the element has been encountered first time, so it can be considered unique. If not, it means the element has been encountered already, so should be discarded now.
var arr = ["X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11"];_x000D_
_x000D_
var filteredArray = arr.filter(function(item, pos){_x000D_
return arr.indexOf(item)== pos; _x000D_
});_x000D_
_x000D_
console.log( filteredArray );

Caveat: As pointed out by rob in the comments, this method should be avoided with very large arrays as it runs in O(N^2)
.
UPDATE (16 Nov 2017)
If you can rely on ES6 features, then you can use Set object and Spread operator to create a unique array from a given array, as already specified in @Travis Heeter's answer below:
var uniqueArray = [...new Set(array)]

I have been experiencing this problem for the last week now as I've been trying to send DELETE requests to my PHP server through AJAX. I recently upgraded my hosting plan where I now have an SSL Certificate on my host which stores the PHP and JS files. Since adding an SSL Certificate I no longer experience this issue. Hoping this helps with this strange error.
Had a similar problem, fixed it by calling python3
instead of python
, my modules were in Python3.5.
I'll assume that the data to transmit is a string.
As other commenters have stated, AJAX is one possible solution, but the cons outweigh the pros: it has a latency and it is harder to program (it needs the code to retrieve the value both server- and client-side), when a simpler escaping function should suffice.
So, we're back to escaping. json_encode($string)
works if you encode the source string as UTF-8 first in case it is not already, because json_encode
requires UTF-8 data. If the string is in ISO-8859-1 then you can simply use json_encode(utf8_encode($string))
; otherwise you can always use iconv
to do the conversion first.
But there's a big gotcha. If you're using it in events, you need to run htmlspecialchars()
on the result in order to make it correct code. And then you have to either be careful to use double quotes to enclose the event, or always add ENT_QUOTES
to htmlspecialchars. For example:
<?php
$myvar = "I'm in \"UTF-8\" encoding and I have <script>script tags</script> & ampersand!";
// Fails:
//echo '<body onload="alert(', json_encode($myvar), ');">';
// Fails:
//echo "<body onload='alert(", json_encode($myvar), ");'>";
// Fails:
//echo "<body onload='alert(", htmlspecialchars(json_encode($myvar)), ");'>";
// Works:
//echo "<body onload='alert(", htmlspecialchars(json_encode($myvar), ENT_QUOTES), ");'>";
// Works:
echo '<body onload="alert(', htmlspecialchars(json_encode($myvar)), ');">';
echo "</body>";
However, you can't use htmlspecialchars
on regular JavaScript code (code enclosed in <script>
...</script>
tags). That makes use of this function prone to mistakes, by forgetting to htmlspecialchars
the result when writing event code.
It's possible to write a function that does not have that problem, and can be used both in events and in regular JavaScript code, as long as you enclose your events always in single quotes, or always in double quotes. Here is my proposal, requiring them to be in double quotes (which I prefer):
<?php
// Optionally pass the encoding of the source string, if not UTF-8
function escapeJSString($string, $encoding = 'UTF-8')
{
if ($encoding != 'UTF-8')
$string = iconv($encoding, 'UTF-8', $string);
$flags = JSON_HEX_TAG|JSON_HEX_AMP|JSON_HEX_APOS|JSON_HEX_QUOT|JSON_UNESCAPED_SLASHES;
$string = substr(json_encode($string, $flags), 1, -1);
return "'$string'";
}
The function requires PHP 5.4+. Example usage:
<?php
$myvar = "I'm in \"UTF-8\" encoding and I have <script>script tags</script> & ampersand!";
// Note use of double quotes to enclose the event definition!
echo '<body onload="alert(', escapeJSString($myvar), ');">';
// Example with regular code:
echo '<script>alert(', escapeJSString($myvar), ');</script>';
echo '</body>';
In the URL you pointed to, the button_text.xml is being used to set the textColor attribute.That it is reason they had the button_text.xml in res/color folder and therefore they used @color/button_text.xml
But you are trying to use it for background attribute. The background attribute looks for something in res/drawable folder.
check this i got this selector custom button from the internet.I dont have the link.but i thank the poster for this.It helped me.have this in the drawable folder

Don't moveTo()
after each lineTo()
In other words, remove every moveTo()
except the first one.
Seriously, if I just copy-paste OP's code and remove the unnecessary moveTo()
calls, it works.
Nothing else needs to be done.
EDIT: I know the OP already posted his "final working solution", but he didn't state why it works. The actual reason was quite surprising to me, so I felt the need to add an answer.
You can use this
<a onClick={() => {window.location.href="/something"}}>Something</a>
A simple solution might be to just store the drawable id in a temporary variable. I'm not sure how practical this would be for your situation but it's definitely a quick fix.
Trying to depict with venn diagrams for better understanding..
Left Semi join : A semi join returns values from the left side of the relation that has a match with the right. It is also referred to as a left semi join.
Note : There is another thing called left anti join : An anti join returns values from the left relation that has no match with the right. It is also referred to as a left anti join.
Inner join : It selects rows that have matching values in both relations.

If you wannt get it inside an activity or fragmnet, then:
getContext().getResources().getString(R.string.string_name);
If you want to get it from a class outside of activity or fragment where you don't have the activity context then use application context:
getApplicationContext().getResources().getString(R.string.string_name);
You can use a deadlock graph

since this question was asked 4 years back..and i didn't realised that unless mentioned by the Questioner..when there were no Run time permissions support.
but hoping it useful for the users who still caught in this situation.. Have a look at Run Time Permissions ,for me it solved the problem when i added Run time permissions to grant camera access. Alternatively you can grant permissions to the app manually by going to your mobile settings=>Apps=>(select your app)=>Permissions section in the appeared window and enable/disable desired permissions. hope this will work.
UPDATE 9 July 2012 - Looks like this is fixed in RTM.
^

so you don't need to add them. (It doesn't appear to be a problem to include them, but you don't need them)View source shows the following:
data-val-regex-pattern="([a-zA-Z0-9 .&'-]+)" <-- MVC 3
data-val-regex-pattern="([a-zA-Z0-9 .&amp;&#39;-]+)" <-- MVC 4/Beta
It looks like we're double encoding.
You seem to be unnecessarily setting properties on your ComboBox
. You can remove the DisplayMemberPath
and SelectedValuePath
properties which have different uses. It might be an idea for you to take a look at the Difference between SelectedItem, SelectedValue and SelectedValuePath post here for an explanation of these properties. Try this:
<ComboBox Name="cbxSalesPeriods"
ItemsSource="{Binding SalesPeriods}"
SelectedItem="{Binding SelectedSalesPeriod}"
IsSynchronizedWithCurrentItem="True"/>
Furthermore, it is pointless using your displayPeriod
property, as the WPF Framework would call the ToString
method automatically for objects that it needs to display that don't have a DataTemplate
set up for them explicitly.
UPDATE >>>
As I can't see all of your code, I cannot tell you what you are doing wrong. Instead, all I can do is to provide you with a complete working example of how to achieve what you want. I've removed the pointless displayPeriod
property and also your SalesPeriodVO
property from your class as I know nothing about it... maybe that is the cause of your problem??. Try this:
public class SalesPeriodV
{
private int month, year;
public int Year
{
get { return year; }
set
{
if (year != value)
{
year = value;
NotifyPropertyChanged("Year");
}
}
}
public int Month
{
get { return month; }
set
{
if (month != value)
{
month = value;
NotifyPropertyChanged("Month");
}
}
}
public override string ToString()
{
return String.Format("{0:D2}.{1}", Month, Year);
}
public virtual event PropertyChangedEventHandler PropertyChanged;
protected virtual void NotifyPropertyChanged(params string[] propertyNames)
{
if (PropertyChanged != null)
{
foreach (string propertyName in propertyNames) PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
PropertyChanged(this, new PropertyChangedEventArgs("HasError"));
}
}
}
Then I added two properties into the view model:
private ObservableCollection<SalesPeriodV> salesPeriods = new ObservableCollection<SalesPeriodV>();
public ObservableCollection<SalesPeriodV> SalesPeriods
{
get { return salesPeriods; }
set { salesPeriods = value; NotifyPropertyChanged("SalesPeriods"); }
}
private SalesPeriodV selectedItem = new SalesPeriodV();
public SalesPeriodV SelectedItem
{
get { return selectedItem; }
set { selectedItem = value; NotifyPropertyChanged("SelectedItem"); }
}
Then initialised the collection with your values:
SalesPeriods.Add(new SalesPeriodV() { Month = 3, Year = 2013 } );
SalesPeriods.Add(new SalesPeriodV() { Month = 4, Year = 2013 } );
And then data bound only these two properties to a ComboBox
:
<ComboBox ItemsSource="{Binding SalesPeriods}" SelectedItem="{Binding SelectedItem}" />
That's it... that's all you need for a perfectly working example. You should see that the display of the items comes from the ToString
method without your displayPeriod
property. Hopefully, you can work out your mistakes from this code example.
Use a document.ready()
event around your call.
$(document).ready(function () {
$('#memberModal').modal('show');
});

I'm using version 4.4.2 and none of the other answers worked for me. But adding useMongoClient

db.close()
I'm surprised that none of the answers reference Object.assign since that's the technique I use whenever I think about "composition" in JavaScript.
And it works as expected in TypeScript:
interface IExisting {

interface INewStuff {
email: string
}
const existingObject: IExisting = {
userName: "jsmith"

const objectWithAllProps: IExisting & INewStuff = Object.assign({}, existingObject, {
email: "[email protected]"
})
console.log(objectWithAllProps.email); // [email protected]
Advantages
any
type at all&
when declaring the type of objectWithAllProps
), which clearly communicates that we're composing a new type on-the-fly (i.e. dynamically)Things to be aware of
existingObject
stays untouched and therefore doesn't have an email
property. For most functional-style programmers, that's a good thing since the result is the only new change).@Chris Haas has explained very well how to use itextSharp

This problem is so complicated and depend on MySQL Version.My problem was happened on MySQL 8.0.2. When I've config my.ini file on notepad and save it.I soleved following @jhersey29 solution https://stackoverflow.com/a/55519014/1764354 but little different approch.
my solution is restore my.ini file and edit config value via Option files on WorkBench Application. workBench Menu Example
querySelector
can be a complete CSS(3)-Selector with IDs and Classes and Pseudo-Classes together like this:
'#id.class:pseudo'
// or
'tag #id .class .class.class'
with getElementsByClassName
you can just define a class
'class'
with getElementById
you can just define an id
'id'
All the answers above are great. Only one thing is missing, be sure to drag the grey buttons to see the table (step number 2):
If speed is what you need and extra dependencies are not a problem, you maybe find numba
quite useful (now it is pretty easy to install, on any platform). The classic ray_tracing
approach you proposed can be easily ported to numba
by using numba @jit
decorator and casting the polygon to a numpy array. The code should look like:
@jit(nopython=True)
def ray_tracing(x,y,poly):
n = len(poly)
inside = False
p2x = 0.0
p2y = 0.0
xints = 0.0
p1x,p1y = poly[0]
for i in range(n+1):
p2x,p2y = poly[i % n]
if y > min(p1y,p2y):
if y <= max(p1y,p2y):
if x <= max(p1x,p2x):
if p1y != p2y:
xints = (y-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
if p1x == p2x or x <= xints:
inside = not inside
p1x,p1y = p2x,p2y
return inside
The first execution will take a little longer than any subsequent call:
%%time
polygon=np.array(polygon)
inside1 = [numba_ray_tracing_method(point[0], point[1], polygon) for
point in points]
CPU times: user 129 ms, sys: 4.08 ms, total: 133 ms
Wall time: 132 ms
Which, after compilation will decrease to:
CPU times: user 18.7 ms, sys: 320 µs, total: 19.1 ms
Wall time: 18.4 ms
If you need speed at the first call of the function you can then pre-compile the code in a module using pycc
. Store the function in a src.py like:
from numba import jit
from numba.pycc import CC
cc = CC('nbspatial')
@cc.export('ray_tracing', 'b1(f8, f8, f8[:,:])')
@jit(nopython=True)
def ray_tracing(x,y,poly):
n = len(poly)
inside = False
p2x = 0.0
p2y = 0.0
xints = 0.0
p1x,p1y = poly[0]
for i in range(n+1):
p2x,p2y = poly[i % n]
if y > min(p1y,p2y):
if y <= max(p1y,p2y):
if x <= max(p1x,p2x):
if p1y != p2y:
xints = (y-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
if p1x == p2x or x <= xints:
inside = not inside
p1x,p1y = p2x,p2y
return inside
if __name__ == "__main__":
cc.compile()
Build it with python src.py
and run:
import nbspatial
import numpy as np
lenpoly = 100
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in
np.linspace(0,2*np.pi,lenpoly)[:-1]]
# random points set of points to test
N = 10000
# making a list instead of a generator to help debug
points = zip(np.random.random(N),np.random.random(N))
polygon = np.array(polygon)
%%time
result = [nbspatial.ray_tracing(point[0], point[1], polygon) for point in points]
CPU times: user 20.7 ms, sys: 64 µs, total: 20.8 ms
Wall time: 19.9 ms
In the numba code I used: 'b1(f8, f8, f8[:,:])'
In order to compile with nopython=True
, each var needs to be declared before the for loop
.
In the prebuild src code the line:
@cc.export('ray_tracing' , 'b1(f8, f8, f8[:,:])')
Is used to declare the function name and its I/O var types, a boolean output b1
and two floats f8
and a two-dimensional array of floats f8[:,:]
as input.
For my use case, I need to check if multiple points are inside a single polygon - In such a context, it is useful to take advantage of numba parallel capabilities to loop over a series of points. The example above can be changed to:
from numba import jit, njit
import numba
import numpy as np
@jit(nopython=True)
def pointinpolygon(x,y,poly):
n = len(poly)
inside = False
p2x = 0.0
p2y = 0.0
xints = 0.0
p1x,p1y = poly[0]
for i in numba.prange(n+1):
p2x,p2y = poly[i % n]
if y > min(p1y,p2y):
if y <= max(p1y,p2y):
if x <= max(p1x,p2x):
if p1y != p2y:
xints = (y-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
if p1x == p2x or x <= xints:
inside = not inside
p1x,p1y = p2x,p2y
return inside
@njit(parallel=True)
def parallelpointinpolygon(points, polygon):
D = np.empty(len(points), dtype=numba.boolean)
for i in numba.prange(0, len(D)):
D[i] = pointinpolygon(points[i,0], points[i,1], polygon)
return D
Note: pre-compiling the above code will not enable the parallel capabilities of numba (parallel CPU target is not supported by pycc/AOT
compilation) see: https://github.com/numba/numba/issues/3336
Test:
import numpy as np
lenpoly = 100
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in np.linspace(0,2*np.pi,lenpoly)[:-1]]
polygon = np.array(polygon)
N = 10000
points = np.random.uniform(-1.5, 1.5, size=(N, 2))
For N=10000
on a 72 core machine, returns:
%%timeit
parallelpointinpolygon(points, polygon)
# 480 µs ± 8.19 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
0
instead of 1
(thanks @mehdi):for i in numba.prange(0, len(D))
Follow-up on the comparison made by @mehdi, I am adding a GPU-based method below. It uses the point_in_polygon
method, from the cuspatial
library:
import numpy as np
import cudf
import cuspatial
N = 100000002
lenpoly = 1000
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in
np.linspace(0,2*np.pi,lenpoly)]
polygon = np.array(polygon)
points = np.random.uniform(-1.5, 1.5, size=(N, 2))
x_pnt = points[:,0]
y_pnt = points[:,1]
x_poly =polygon[:,0]
y_poly = polygon[:,1]
result = cuspatial.point_in_polygon(
x_pnt,
y_pnt,
cudf.Series([0], index=['geom']),
cudf.Series([0], name='r_pos', dtype='int32'),
x_poly,
y_poly,
)
Following @Mehdi comparison. For N=100000002
and lenpoly=1000
- I got the following results:
time_parallelpointinpolygon: 161.54760098457336
time_mpltPath: 307.1664695739746
time_ray_tracing_numpy_numba: 353.07356882095337
time_is_inside_sm_parallel: 37.45389246940613
time_is_inside_postgis_parallel: 127.13793849945068
time_is_inside_rapids: 4.246025562286377
hardware specs:
Notes:
The cuspatial.point_in_poligon
method, is quite robust and powerful, it offers the ability to work with multiple and complex polygons (I guess at the expense of performance)
The numba
methods can also be 'ported' on the GPU - it will be interesting to see a comparison which includes a porting to cuda
of fastest method mentioned by @Mehdi (is_inside_sm
).
If you have a res/raw
folder, be sure to add a file with a valid filename, otherwise the entire folder won't show up in the R class. If there's an error with a filename, it will appear in red in the console.
Use:
MessageBoxResult m = MessageBox.Show("The file will be saved here.", "File Save", MessageBoxButton.OKCancel);
if(m == m.Yes)
{
// Do something
}
else if (m == m.No)
{
// Do something else

MessageBoxResult is used on Windows Phone instead of DialogResult...
You Can Now Delete App.
On October 4, 2018, Apple released a new update of the appstoreconnect (previously iTunesConnect).
It's now easier to manage apps you no longer need in App Store Connect by removing them from your main view in My Apps, even if they haven't been submitted for approval. You must have the Legal or Admin role to remove apps.
From the homepage, click My Apps, then choose the app you want to remove. Scroll to the Additional Information section, then click Remove App. In the dialog that appears, click Remove. You can restore a removed app at any time, as long as the app name is not currently in use by another developer.
From the homepage, click My Apps. In the upper right-hand corner, click the arrow next to All Statuses. From the drop-down menu, choose Removed Apps. Choose the app you want to restore. Scroll to the Additional Information section, then click Restore App.
You can show the removed app by clicking on all Statuses on the top right of the screen and then select Removed Apps. Thank you @Daniel for the tips.
Please note:
you can only remove apps if all versions of that app are in one of the following states: Prepare for Submission, Invalid Binary, Developer Rejected, Rejected, Metadata Rejected, Developer, Removed from Sale.
Add this to your pom.xml file:
<project ....>
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>
</project>
Where 1.7 is the Java version you intend to use. This overwrites the Maven compiler setting, so it's good to debug from here.
With the Array object methods you can modify the Array content yet compared to the basic for loops, these methods lack one important functionality. You can not modify the index on the run.
For example if you will remove the current element and place it to another index position within the same array you can easily do this. If you move the current element to a previous position there is no problem in the next iteration you will get the same next item as if you hadn't done anything.
Consider this code where we move the item at index position 5 to index position 2 once the index counts up to 5.
var ar = [0,1,2,3,4,5,6,7,8,9];
ar.forEach((e,i,a) => {
i == 5 && a.splice(2,0,a.splice(i,1)[0])
console.log(i,e);
}); // 0 0 - 1 1 - 2 2 - 3 3 - 4 4 - 5 5 - 6 6 - 7 7 - 8 8 - 9 9
However if we move the current element to somewhere beyond the current index position things get a little messy. Then the very next item will shift into the moved items position and in the next iteration we will not be able to see or evaluate it.
Consider this code where we move the item at index position 5 to index position 7 once the index counts up to 5.
var a = [0,1,2,3,4,5,6,7,8,9];
a.forEach((e,i,a) => {
i == 5 && a.splice(7,0,a.splice(i,1)[0])
console.log(i,e);
}); // 0 0 - 1 1 - 2 2 - 3 3 - 4 4 - 5 5 - 6 7 - 7 5 - 8 8 - 9 9
So we have never met 6 in the loop. Normally in a for loop you are expected decrement the index value when you move the array item forward so that your index stays at the same position in the next run and you can still evaluate the item shifted into the removed item's place. This is not possible with array methods. You can not alter the index. Check the following code
var a = [0,1,2,3,4,5,6,7,8,9];
a.forEach((e,i,a) => {
i == 5 && (a.splice(7,0,a.splice(i,1)[0]), i--);
console.log(i,e);
}); // 0 0 - 1 1 - 2 2 - 3 3 - 4 4 - 4 5 - 6 7 - 7 5 - 8 8 - 9 9
As you see when we decrement i
it will not continue from 5 but 6, from where it was left.
So keep this in mind.

If you have pressed any keys (whether typing characters or just moving the cursor) since your last undo command, there is no need to type C-g
before your next undo/redo. C-g
is just a safe key to hit that does nothing on its own, but counts as a non-undo key to signal the end of your undo sequence. Pressing another command such as C-f
would work too; it’s just that it would move the cursor from where you had it.
If you hit C-g
or another command when you didn’t mean to, and you are now undoing in the wrong direction, simply hit C-g
to reverse your direction again. You will have to undo all the way through your accidental redos and undos before you get to the undos you want, but if you just keep hitting C-/
, you will eventually reach the state you want. In fact, every state the buffer has ever been in is reachable, if you hit C-g
once and then press C-/
enough times.
Alternative shortcuts for undo

.
See Undo in the Emacs Manual for more details on Emacs’s undo system.
Just to expand on this error in the context of an interface, if you are type hinting your function parameters like so:
interface A
use Bar;
interface A
{
public function foo(Bar $b);
}
Class B
class B implements A
{
public function foo(Bar $b);
}
If you have forgotten to include the use
statement on your implementing class (Class B), then you will also get this error even though the method parameters are identical.
In MySQL, It should be like this
INSERT INTO this_table_archive (col1, col2, ..., coln)
SELECT col1, col2, ..., coln
FROM this_table
WHERE entry_date < '2011-01-01 00:00:00';
Had to try this:
cd
commandjava.exe -jar *filename*.jar
The app should pop right after that.

If you want to add wsdl reference in .Net Core project, there is no "Add web reference" option.
To add the wsdl reference go to Solution Explorer, right-click on the References project item and then click on the Add Connected Service option.
Then click 'Microsoft WCF Web Service Reference':
Enter the file path into URI text box and import the WSDL:
It will generate a simple, very basic WCF client and you to use it something like this:
YourServiceClient client = new YourServiceClient();
client.DoSomething();
You can't set a number in an arbitrary place in the array without telling the array how big it needs to be. For your example: int[] array = new int[4];
In regards to your question about newlines and carriage returns:
I would recommend using the predefined global constant PHP_EOL as it will solve any cross-platform compatibility issues.
This question has been raised on SO beforehand and you can find out more information by reading "When do I use the PHP constant PHP_EOL"
If you need to add emails as CC or BCC, add the following part in the variable you use as for your header :
$headers .= "CC: [email protected]".PHP_EOL;
$headers .= "BCC: [email protected]".PHP_EOL;

Currently, I am using Ubuntu 16.04 LTS. Me too was facing same problem while Fetching the Postgress Database values using Php so i resolved it by using the below commands.
Mine PHP version is 7.0, so i tried the below command.
apt-get install php-pgsql
Remember to restart Apache.

You can use following syntax to get attribute value from html element
//to retrieve html element
const element = fixture.debugElement.nativeElement.querySelector('name of element'); // example a, h1, p
//get attribute value from that element

Convert the string to an integer base 16 then to hexadecimal.
print hex(int(string, base=16))
These are built-in functions.
http://docs.python.org/2/library/functions.html#int
Example
>>> string = 'AA'
>>> _int = int(string, base=16)
>>> _hex = hex(_int)
>>> print _int
170
>>> print _hex
0xaa
>>>
You can get that error if you have an object with the same name as the schema. For example:
create sequence s2;
begin
s2.a;
end;
/
ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored
When you refer to S2.MY_FUNC2
the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2
there is no confusion, so it works.
The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.
It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.
select owner, object_type, object_name
from all_objects
where object_name = 'S2';
You should remove .Value
from all option buttons because option buttons don't hold the resultant value, the option group control does. If you omit .Value
then the default interface will report the option button status, as you are expecting. You should write all relevant code under commandbutton_click events because whenever the commandbutton is clicked the option button action will run.
If you want to run action code when the optionbutton is clicked then don't write an if loop for that.
EXAMPLE:
Sub CommandButton1_Click
If OptionButton1 = true then
(action code...)
End if
End sub
Sub OptionButton1_Click
(action code...)
End sub
What worked here : on the client
1) ssh-add
2) ssh-copy-id user@server
The keys has been created some time ago with plain "ssh-keygen -t rsa" I sw the error message because I copied across my ssh public key from client to server (with ssh-id-copy) without running ssh-add first, since I erroneously assumed I'd added them some time earlier.

Looks like this issue can be reproduced while folowing mentioned tutorial on unix machines. Also noticed that author uses TC 8.0.33
Win (and OSX) do not have such issue, at least on my env:

If you want result to be stored in another dataset:
df.drop_duplicates(keep=False)
or
df.drop_duplicates(keep=False, inplace=False)
If same dataset needs to be updated:

Can't you originally get the data as a JSONObject?
Perhaps parse the string as both a JSONObject and a JSONArray in the first place? Where is the JSON string coming from?
I'm not sure that it is possible to convert a JsonArray into a JsonObject.
I presume you are using the following from json.org
JSONObject.java
A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having get() and opt() methods for accessing the values by name, and put() methods for adding or replacing values by name. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.
JSONArray.java
A JSONArray is an ordered sequence of values. Its external form is a string wrapped in square brackets with commas between the values. The internal form is an object having get() and opt() methods for accessing the values by index, and put() methods for adding or replacing values. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.
This works for me
msg.BodyFormat = MailFormat.Html;
and then you can use html in your body
msg.Body = "<em>It's great to use HTML in mail!!</em>"
wait
also (optionally) takes the PID of the process to wait for, and with $! you get the PID of the last command launched in background.
Modify the loop to store the PID of each spawned sub-process into an array, and then loop again waiting on each PID.
# run processes and store pids in array
for i in $n_procs; do
./procs[${i}] &
pids[${i}]=$!
done
# wait for all pids
for pid in ${pids[*]}; do
wait $pid
done
You may call U.difference(lists)
method in underscore-java library. I am the maintainer of the project. Live example
import com.github.underscore.U;
import java.util.Arrays;
import java.util.List;
public class Main {
public static void main(String[] args) {
List<Integer> list1 = Arrays.asList(1, 2, 3);
List<Integer> list2 = Arrays.asList(1, 2);
List<Integer> list3 = U.difference(list1, list2);
System.out.println(list3);
// [3]
}
}
To have something like One, two and three you should add one more css style
li:nth-last-child(2):after {
content: ' ';
}
This would remove the comma from the second last element.

If you want to set it to LF as default, you can go to File->Preferences->Settings and under user settings you can paste this line in below your other user settings.
"files.eol": "\n"
For example.
"git.confirmSync": false,
"window.zoomLevel": -1,
"workbench.activityBar.visible": true,
"editor.wordWrap": true,
"workbench.iconTheme": "vscode-icons",
"window.menuBarVisibility": "default",
"vsicons.projectDetection.autoReload": true,
"files.eol": "\n"
You can sort an array ([...]
) with the .sort
function:
var people = [
{'name': 'a75', 'item1': false, 'item2': false},
{'name': 'z32', 'item1': true, 'item2': false},
{'name': 'e77', 'item1': false, 'item2': false},
];
var sorted = people.sort(function IHaveAName(a, b) { // non-anonymous as you ordered...
return b.name < a.name ? 1 // if b should come earlier, push a to end
: b.name > a.name ? -1 // if b should come later, push a to begin
: 0; // a and b are equal
});
function mydump(arr,level) {
var dumped_text = "";
if(!level) level = 0;
var level_padding = "";
for(var j=0;j<level+1;j++) level_padding += " ";
if(typeof(arr) == 'object') {
for(var item in arr) {
var value = arr[item];
if(typeof(value) == 'object') {
dumped_text += level_padding + "'" + item + "' ...\n";
dumped_text += mydump(value,level+1);
} else {
dumped_text += level_padding + "'" + item + "' => \"" + value + "\"\n";
}
}
} else {
dumped_text = "===>"+arr+"<===("+typeof(arr)+")";
}
return dumped_text;
}
A slightly less verbose way of declaring named enumerations:
object WeekDay extends Enumeration("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat") {
type WeekDay = Value
val Sun, Mon, Tue, Wed, Thu, Fri, Sat = Value
}
WeekDay.valueOf("Wed") // returns Some(Wed)
WeekDay.Fri.toString // returns Fri
Of course the problem here is that you will need to keep the ordering of the names and vals in sync which is easier to do if name and val are declared on the same line.
Swift 5
Add these protocols
- `UICollectionViewDelegate`
- `UICollectionViewDataSource`
- `UICollectionViewDelegateFlowLayout`
Your code will then look like this
extension YourViewController: UICollectionViewDelegate {
//Write Delegate Code Here
}
extension YourViewController: UICollectionViewDataSource {
//Write DataSource Code Here
}
extension YourViewController: UICollectionViewDelegateFlowLayout {
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: screenWidth, height: screenWidth)
}
}
Now the final and crucial step to see this take effect is to go to your viedDidLoad function inside your Viewcontroller.
override func viewDidLoad() {
super.viewDidLoad()
collection.dataSource = self // Add this
collection.delegate = self // Add this
// Do any additional setup after loading the view.
}
Without telling your view which class the delegate is it won't work.
in javascript you cant give to a class (constructor function) 2 different prototype object and because inheritance in javascript work with prototype soo you cant do use more than 1 inheritance for one class but you can aggregate and join property of Prototype object and that main property inside a class manually with refactoring that parent classes and next extends that new version and joined class to your target class have code for your question :
let Join = (...classList) => {
class AggregatorClass {
constructor() {
classList.forEach((classItem, index) => {
let propNames = Object.getOwnPropertyNames(classItem.prototype);
propNames.forEach(name => {
if (name !== 'constructor') {
AggregatorClass.prototype[name] = classItem.prototype[name];
}
});
});
classList.forEach(constructor => {
Object.assign(AggregatorClass.prototype, new constructor())
});
}
}
return AggregatorClass
};
"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.
Check that you don't send ANY content before calling session_start
. Better yet, just make session_start
the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).
You can convert your string to a DateTime
value like this:
DateTime date = DateTime.Parse(something);
You can convert a DateTime
value to a formatted string like this:
date.ToString("yyyyMMdd");
The Address property of a cell can get this for you:
MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)
returns A1
.
The other way around can be done with the Row
and Column
property of Range
:
MsgBox Range("A1").Row & ", " & Range("A1").Column
returns 1,1
.
I find this way is the nicest:
{this.state.yourVariable === 'news' && <Text>{data}<Text/>}
Here you go:
$( table ).delegate( '.tr_clone_add', 'click', function () {
var thisRow = $( this ).closest( 'tr' )[0];
$( thisRow ).clone().insertAfter( thisRow ).find( 'input:text' ).val( '' );
});
Live demo: http://jsfiddle.net/RhjxK/4/
Update: The new way of delegating events in jQuery is
$(table).on('click', '.tr_clone_add', function () { … });
Additional to putting the variable in quotation, one could also translate the output of the variable using tr
and converting spaces to newlines.
$ echo $var | tr " " "\n"
foo
bar
baz
Although this is a little more convoluted, it does add more diversity with the output as you can substitute any character as the separator between array variables.
You can use querySelectorAll to get all span elements and then use new ES2015 (ES6) spread operator convert StaticNodeList that querySelectorAll returns to array of spans, and then use map operator to get list of items.
See example bellow
([...document.querySelectorAll('#test span')]).map(x => console.log(x.innerHTML))
_x000D_
<div id="test">_x000D_
<span>1</span>_x000D_
<span>2</span>_x000D_
<span>3</span>_x000D_
<span>4</span>_x000D_
<div>
_x000D_
time = Time.now.getutc
Rationale: In my eyes a timestamp is exactly that: A point in time. This can be accurately represented with an object. If you need anything else, a scalar value, e.g. seconds since the Unix epoch, 100-ns intervals since 1601 or maybe a string for display purposes or storing the timestamp in a database, you can readily get that from the object. But that depends very much on your intended use.
Saying that »a true timestamp is the number of seconds since the Unix epoch« is a little missing the point, as that is one way of representing a point in time, but it also needs additional information to even know that you're dealing with a time and not a number. A Time
object solves this problem nicely by representing a point in time and also being explicit about what it is.
MS-SQL has a setting to prevent recursive trigger firing. This is confirgured via the sp_configure stored proceedure, where you can turn recursive or nested triggers on or off.
In this case, it would be possible, if you turn off recursive triggers to link the record from the inserted table via the primary key, and make changes to the record.
In the specific case in the question, it is not really a problem, because the result is to delete the record, which won't refire this particular trigger, but in general that could be a valid approach. We implemented optimistic concurrency this way.
The code for your trigger that could be used in this way would be:
ALTER TRIGGER myTrigger
ON someTable
AFTER INSERT
AS BEGIN
DELETE FROM someTable
INNER JOIN inserted on inserted.primarykey = someTable.primarykey
WHERE ISNUMERIC(inserted.someField) = 1
END
As of .NET 5, the implementation has changed. HttpClient
still throws a TaskCanceledException
, but now wraps a TimeoutException
as InnerException
. So you can easily check whether a request was canceled or timed out (code sample copied from linked blog post):
try
{
using var response = await _client.GetAsync("http://localhost:5001/sleepFor?seconds=100");
}
// Filter by InnerException.
catch (TaskCanceledException ex) when (ex.InnerException is TimeoutException)
{
// Handle timeout.
Console.WriteLine("Timed out: "+ ex.Message);
}
catch (TaskCanceledException ex)
{
// Handle cancellation.
Console.WriteLine("Canceled: " + ex.Message);
}
Be careful of difference between 'c'
and "c"
'c'
is a char suitable for formatting with %c
"c"
is a char* pointing to a memory block with a length of 2 (with the null terminator).
A general purpose image rotation, position, and scale.
// no need to use save and restore between calls as it sets the transform rather
// than multiply it like ctx.rotate ctx.translate ctx.scale and ctx.transform
// Also combining the scale and origin into the one call makes it quicker
// x,y position of image center
// scale scale of image
// rotation in radians.
function drawImage(image, x, y, scale, rotation){
ctx.setTransform(scale, 0, 0, scale, x, y); // sets scale and origin
ctx.rotate(rotation);
ctx.drawImage(image, -image.width / 2, -image.height / 2);
}
If you wish to control the rotation point use the next function
// same as above but cx and cy are the location of the point of rotation
// in image pixel coordinates
function drawImageCenter(image, x, y, cx, cy, scale, rotation){
ctx.setTransform(scale, 0, 0, scale, x, y); // sets scale and origin
ctx.rotate(rotation);
ctx.drawImage(image, -cx, -cy);
}
To reset the 2D context transform
ctx.setTransform(1,0,0,1,0,0); // which is much quicker than save and restore
Thus to rotate image to the left (anti clockwise) 90 deg
drawImage(image, canvas.width / 2, canvas.height / 2, 1, - Math.PI / 2);

Update December 2019 ionic - 4.7.1
<manifest xmlns:tools=“http://schemas.android.com/tools”>
<application android:usesCleartextTraffic=“true” tools:targetApi=“28”>
Please add above content in android manifest .xml file
Previous Versions of ionic
Make sure you have the following in your config.xml
in Ionic Project:
<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application" xmlns:android="http://schemas.android.com/apk/res/android">
<application android:networkSecurityConfig="@xml/network_security_config" />
<application android:usesCleartextTraffic="true" />
</edit-config>
Run ionic Cordova build android. It creates Android folder under Platforms
Open Android Studio and open the Android folder present in our project project-platforms-android. Leave it for few minutes so that it builds the gradle
After gradle build
is finished we get some errors for including minSdVersion
in manifest.xml
.
Now what we do is just remove <uses-sdk android:minSdkVersion="19" />
from manifest.xml
.
Make sure its removed from both the locations:
AndroidManifest.xml
.AndroidManifest.xml
.Now try to build the gradle again and now it builds successfully
Make sure you have the following in Application tag in App → manifest → Androidmanifest.xml
:
<application
android:networkSecurityConfig="@xml/network_security_config" android:usesCleartextTraffic="true" >
Open network_security_config
(app → res → xml → network_security_config.xml
).
Add the following code:
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">xxx.yyyy.com</domain>
</domain-config>
</network-security-config>
Here xxx.yyyy.com
is the link of your HTTP API. Make sure you don't include any Http before the URL.
Note: Now build the app using Android Studio (Build -- Build Bundle's/APK -- Build APK) and now you can use that App and it works fine in Android Pie. If you try to build app using ionic Cordova build android it overrides all these settings so make sure you use Android Studio to build the Project.
If you have any older versions of app installed, Uninstall them and give a try or else you will be left with some error:
App not Installed
In addition to S.Lott's answer and as becomingGuru mentioned in comments, its possible to add the queryset filters by overriding the ModelForm.__init__
function. (This could easily apply to regular forms) it can help with reuse and keeps the view function tidy.
class ClientForm(forms.ModelForm):
def __init__(self,company,*args,**kwargs):
super (ClientForm,self ).__init__(*args,**kwargs) # populates the post
self.fields['rate'].queryset = Rate.objects.filter(company=company)
self.fields['client'].queryset = Client.objects.filter(company=company)
class Meta:
model = Client
def addclient(request, company_id):
the_company = get_object_or_404(Company, id=company_id)
if request.POST:
form = ClientForm(the_company,request.POST) #<-- Note the extra arg
if form.is_valid():
form.save()
return HttpResponseRedirect(the_company.get_clients_url())
else:
form = ClientForm(the_company)
return render_to_response('addclient.html',
{'form': form, 'the_company':the_company})
This can be useful for reuse say if you have common filters needed on many models (normally I declare an abstract Form class). E.g.
class UberClientForm(ClientForm):
class Meta:
model = UberClient
def view(request):
...
form = UberClientForm(company)
...
#or even extend the existing custom init
class PITAClient(ClientForm):
def __init__(company, *args, **args):
super (PITAClient,self ).__init__(company,*args,**kwargs)
self.fields['support_staff'].queryset = User.objects.exclude(user='michael')
Other than that I'm just restating Django blog material of which there are many good ones out there.
Suppose you have less data, I suggest to try 70%, 80% and 90% and test which is giving better result. In case of 90% there are chances that for 10% test you get poor accuracy.
You could use ChromeOptions and set suitable argument:
options = ChromeOptions()
options.add_argument("--start-maximized")
driver = ChromeDriver(options)
To delete file:
del PATH_TO_FILE
To delete folder with all files in it:
rmdir /s /q PATH_TO_FOLDER
To delete all files from specific folder (not deleting folder itself) is a little bit complicated. del /s *.*
cannot delete folders, but removes files from all subfolder. So two commands are needed:
del /q PATH_TO_FOLDER\*.*
for /d %i in (PATH_TO_FOLDER\*.*) do @rmdir /s /q "%i"
Just gave the package openxlsx
a try today. It worked really well (and fast).
