If you are adding a loading view (an activity indicator view for instance), make sure you have an object of UIWindow class. If you show an action sheet just before you show your loading view, the keyWindow
will be the UIActionSheet
and not UIWindow
. And since the action sheet will go away, the loading view will go away with it. Or that's what was causing me problems.
UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
if (![NSStringFromClass([keyWindow class]) isEqualToString:@"UIWindow"]) {
// find uiwindow in windows
NSArray *windows = [UIApplication sharedApplication].windows;
for (UIWindow *window in windows) {
if ([NSStringFromClass([window class]) isEqualToString:@"UIWindow"]) {
keyWindow = window;
break;
}
}
}
This should do it

To start Microsoft Word for example, use this code:
private void button1_Click(object sender, EventArgs e)
{
string ProgramName = "winword.exe";
Process.Start(ProgramName);
}

For a side note, I personally use [Foo new]
if I want something in init to be done without using it's return value anywhere. If you do not use the return of [[Foo alloc] init]
anywhere then you will get a warning. More or less, I use [Foo new]
for eye candy.
<div class="modal fade" id="myModal" aria-hidden="true">

What you are looking for is this:
SHOW VARIABLES;
You can modify it further like any query:
SHOW VARIABLES LIKE '%max%';
Like the above stated, you can't change the background images in the animation. I've found the best solution to be to put your images into one sprite sheet, and then animate by changing the background position, but if you're building for mobile, your sprite sheets are limited to less than 1900x1900 px.
You can achieve this with Collections framework. Put all your options in a Collection say something like Collection<String> options
;
Then loop throgh this to compare your string with the list elements and if it is you can return a boolean value true and otherwise false.
Starting an Activity is not the right approach for this behavior. Instead have your BroadcastReceiver use an intent to start a Service which can continue to run as long as possible. (See http://developer.android.com/reference/android/app/Service.html#ProcessLifecycle)

This command did it for me:
zip -r Target.zip Source -x "*.DS_Store"
Target.zip
is the zip file to create. Source
is the source file/folder to zip up. And the _x
parameter specifies the file/folder to not include. If the above doesn't work for whatever reason, try this instead:
zip -r Target.zip Source -x "*.DS_Store" -x "__MACOSX"
The memory for a & b is not allocated by you. The compiler is free to choose a read-only memory location to store the characters. So if you try to change it may result in seg fault. So I suggest you to create a character array yourself. Something like: char a[10]; strcpy(a, "Hello");
There are many toolboxes. Since you mentioned one that is commercially available from MathWorks, I assume you mean how do you get a trial/license
http://www.mathworks.com/products/image/
There is a link for trials, purchase, demos. This will get you in touch with your sales representative. If you know your sales representative, you could just call to get attention faster.
If you mean just a general toolbox that is from a source other than MathWorks, I would check with the producer, as it will vary widely from "Put it on your path." to whatever their purchase and licensing procedure is.
You can also try Altair or ggpot which are focused on declarative visualisations.
import numpy as np
import pandas as pd
np.random.seed(1974)
# Generate Data
num = 20
x, y = np.random.random((2, num))
labels = np.random.choice(['a', 'b', 'c'], num)
df = pd.DataFrame(dict(x=x, y=y, label=labels))
from altair import Chart
c = Chart(df)
c.mark_circle().encode(x='x', y='y', color='label')
from ggplot import *
ggplot(aes(x='x', y='y', color='label'), data=df) +\

I just wanted to answer that question for Cocoa Swift programmers. This function returns NSImage with new size. You can use that function like this.
let sizeChangedImage = changeImageSize(image, ratio: 2)
// changes image size
func changeImageSize (image: NSImage, ratio: CGFloat) -> NSImage {
// getting the current image size
let w = image.size.width
let h = image.size.height
// calculating new size
let w_new = w / ratio
let h_new = h / ratio
// creating size constant
let newSize = CGSizeMake(w_new ,h_new)
//creating rect
let rect = NSMakeRect(0, 0, w_new, h_new)
// creating a image context with new size
let newImage = NSImage.init(size:newSize)
newImage.lockFocus()
// drawing image with new size in context
image.drawInRect(rect)
newImage.unlockFocus()
return newImage
}
You should be able to add the Java Development Tools by selecting 'Help' -> 'Install New Software', there you select the 'Juno' update site, then 'Programming Languages' -> 'Eclipse Java Development Tools'.
After that, you will be able to run your JUnit tests with 'Right Click' -> 'Run as' -> 'JUnit test'.
why dont you add a "source" column to each of the queries with a static value like
select 'source 1' as Source, column1, column2...
from table1
UNION ALL
select 'source 2' as Source, column1, column2...
from table2
If anyone is still facing this issue, Captor annotation worked for me
@Captor
private ArgumentCaptor<Object> argumentCaptor;
Then I was able to mock the request by:
ResponseEntity<YourTestResponse> testEntity = new ResponseEntity<>(
getTestFactoryResponse(),
HttpStatus.OK);
when(mockRestTemplate.exchange((String) argumentCaptor.capture(),
(HttpMethod) argumentCaptor.capture(),
(HttpEntity<?>) argumentCaptor.capture(),
(Class<YourTestResponse.class>) any())
).thenReturn(testEntity);
The configuration could be made as follows:
@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcAutoConfigurationAdapter {
// specific project configuration
}
Important here is that your WebMvcConfig
may override addResourceHandlers
method and therefore you need to explicitly invoke super.addResourceHandlers(registry)
(it is true that if you are satisfied with the default resource locations you don't need to override any method).
Another thing that needs to be commented here is that those default resource locations (/static
, /public
, /resources
and /META-INF/resources
) will be registered only if there isn't already a resource handler mapped to /**
.
From this moment on, if you have an image on src/main/resources/static/images
named image.jpg
for instance, you can access it using the following URL: http://localhost:8080/images/image.jpg
(being the server started on port 8080 and application deployed to root context).
Because in 2nd case you adding same reference twice and HashSet
have check against this in HashMap.put()
on which HashSet
is based:
if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
V oldValue = e.value;
e.value = value;
e.recordAccess(this);
return oldValue;
}
As you can see, equals
will be called only if hash of key being added equals to the key already present in set and references of these two are different.
//assuming b is BOOL. ternary operator helps us in any language.
NSLog(@"result is :%@",((b==YES)?@"YES":@"NO"));
I think you shouldn't prepend themesDir
. You only pass the filename of the template to flask, it will then look in a folder called templates
relative to your python file.
adb shell
am start -n com.package.name/com.package.name.ActivityName
Or you can use this directly:
adb shell am start -n com.package.name/com.package.name.ActivityName
You can also specify actions to be filter by your intent-filters:
am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName

To change the actual local market:
Basically the market is determined automatically based on your IP. You can change some local country settings from your Gmail account settings but still IP of the country you're browsing from is more important. To go around it you'd have to Proxy-cheat. Check out some ways/sites: http://www.affilorama.com/forum/market-research/how-to-change-country-search-settings-in-google-t4160.html
To do it from an Android phone you'd need to find an app. I don't have my Droid anymore but give this a try: http://forum.xda-developers.com/showthread.php?t=694720
The best way to do this is by running the command:
git diff --name-only --cached
When you check the manual you will likely find the following:
--name-only
Show only names of changed files.
And on the example part of the manual:
git diff --cached
Changes between the index and your current HEAD.
Combined together you get the changes between the index and your current HEAD
and Show only names of changed files.
Update: --staged
is also available as an alias for --cached
above in more recent git versions.
Because JSON has a string data type (which is practically anything between "
and "
). It does not have a data type that matches something
Replacing one string with another can be done in the below methods
Method 1: Using String replaceAll
String myInput = "HelloBrother";
String myOutput = myInput.replaceAll("HelloBrother", "Brother"); // Replace hellobrother with brother
---OR---
String myOutput = myInput.replaceAll("Hello", ""); // Replace hello with empty
System.out.println("My Output is : " +myOutput);
Method 2: Using Pattern.compile
import java.util.regex.Pattern;
String myInput = "JAVAISBEST";
String myOutputWithRegEX = Pattern.compile("JAVAISBEST").matcher(myInput).replaceAll("BEST");
---OR -----
String myOutputWithRegEX = Pattern.compile("JAVAIS").matcher(myInput).replaceAll("");
System.out.println("My Output is : " +myOutputWithRegEX);
Method 3: Using Apache Commons
as defined in the link below:
http://commons.apache.org/proper/commons-lang/javadocs/api-z.1/org/apache/commons/lang3/StringUtils.html#replace(java.lang.String, java.lang.String, java.lang.String)

If you are using -specs=/usr/lib/rpm/redhat/redhat-hardened-ld at link time,
you also need to use -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 at compile time, and as you are compiling and linking at the same time, you need either both, or drop the -specs=/usr/lib/rpm/redhat/redhat-hardened-ld .

As @ashishduh mentioned above, using android:autoLink="phone
is also a good solution. But this option comes with one drawback, it doesn't work with all phone number lengths. For instance, a phone number of 11 numbers won't work with this option. The solution is to prefix your phone numbers with the country code.
Example:
08034448845
won't work
but +2348034448845
will
Correct answer is simply:
SELECT a.group_id
FROM a
LEFT JOIN b ON a.group_id=b.group_id and b.user_id = 4
where b.user_id is null
and a.keyword like '%keyword%'
Here we are checking user_id = 4
(your user id from the session). Since we have it in the join criteria, it will return null values for any row in table b that does not match the criteria - ie, any group that that user_id is NOT in.
From there, all we need to do is filter for the null values, and we have all the groups that your user is not in.
Another alternative is to use Pycharm IDE. For each project, you can set the Project Interpreter in Settings.
For example, if anaconda is installed in /home/user/anaconda2/bin/python, you can select the Project Interpreter and set to this folder.
Since the whole project is set to Anaconda's path, you can import any module which is packaged within Anaconda.
You have to call close()
on the GZIPOutputStream
before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush()
probably won't help ... though calling finish()
instead of close()
should work. Look at the javadocs.)
Here's the correct code (in Java);
package test;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;
public class GZipTest {
public static void main(String[] args) throws
FileNotFoundException, IOException {
String name = "/tmp/test";
GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
gz.write(10);
gz.close(); // Remove this to reproduce the reported bug
System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
}
}
(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)
I ran into this issue by being a bit silly. I use nvm to manage my different versions of node, and installed react-native into a version of node that was not my default. Upon opening a new shell, I lost my command. :) Switching back of course fixed things.

Here is an efficient solution for fast creation of a randomized array. After randomization you can simply pick the n
-th element e
of the array, increment n
and return e
. This solution has O(1) for getting a random number and O(n) for initialization, but as a tradeoff requires a good amount of memory if n gets large enough.
There is two steps to extract year for all the dataframe without using method apply.
Step1
convert the column to datetime :
df['ArrivalDate']=pd.to_datetime(df['ArrivalDate'], format='%Y-%m-%d')
Step2
extract the year or the month using DatetimeIndex()
method
pd.DatetimeIndex(df['ArrivalDate']).year
The regex way:
var matches = !!location.href.match(/franky/); //a boolean value now
Or in a simple statement you could use:
if (location.href.match(/franky/)) {
I use this to test whether the website is running locally or on a server:
location.href.match(/(192.168|localhost).*:1337/)
This checks whether the href contains either 192.168
or localhost
AND is followed by :1337
.
As you can see, using regex has its advantages over the other solutions when the condition gets a bit trickier.
ln -s /usr/local/bin/python2.7 /usr/bin/python
I found the solution thanks to the link in Vincent's answer.
\renewcommand{\familydefault}{\sfdefault}
This changes the default font family to sans-serif.
It depends on the package. If the Makefile is generated by GNU autotools (./configure
) you can usually set the target location like so:
./configure --prefix=/somewhere/else/than/usr/local
If the Makefile is not generated by autotools, but distributed along with the software, simply open it up in an editor and change it. The install target directory is probably defined in a variable somewhere.
If you want to see which IP addresses are in use on a specific subnet then there are several different IP Address managers.

Follow following step to work genemotion like charm.
Open Oracle VM virtual Box
File -> Preferences ( ctrl + g ) -> open one dialog box -> select Network -> select Host only network choose you adapter ( there are three button on right side -add -remove -Edit host only nw.,
If you dont have any adapter then create.
After selecting your adapater choose Edit Edit host only network(space)
Open one dialog box then choose DHCP server choose Enable Server and fill all ip addresses.
like
IPv4 address/netmask: 192.168.56.1/255.255.255.0 (on Adapter tab)
DHCP server enabled checked (on DHCP server tab)
Server address/netmask: 192.168.56.100/255.255.255.0
Server lower/upper address: 192.168.56.100/192.168.56.254
Give ok.
In starting of the oracle virtual machine there are different tab like General ,system , Display ,storage,Network etc.. Click on Network
Open one dialog box, select Enable Network adapter attached to ->host only network and main thing is that in Name tab, choose adapter that you are choosing in preference both adapter much be match example you choose virtualbox...2 then here also choose that one.
Ok.
Now play your genemotion. if again error come then again restart to play you succedd.
:)
See full video here to see above all step and work well with genemotion.
UPDATE: Added C# code, and link to Windows Jobs
I spent sometime trying to figure out this problem, and at the time XtremeVBTalk was the most active and responsive. Here is a link to my original post, Closing an Excel Interop process cleanly, even if your application crashes. Below is a summary of the post, and the code copied to this post.
Application.Quit()
and Process.Kill()
works for the most part, but fails if the applications crashes catastrophically. I.e. if the app crashes, the Excel process will still be running loose.I found this to be a clean solution because the OS is doing real work of cleaning up. All you have to do is register the Excel process.

For CentOS: When installing php-gd you need to specify the version. I fixed it by running: sudo yum install php55-gd
I thought there were a few perfectly fine answers, but no concise summary of all possibilities; thus:
The core principal behind most answers here is redirection. Two are important redirection operators for writing to files:
echo 'text to completely overwrite contents of myfile' > myfile
echo 'text to add to end of myfile' >> myfile
Others mentioned, rather than from a fixed input source like echo 'text'
, you could also interactively write to files via a "Here Document", which are also detailed in the link to the bash manual above. Those answers, e.g.
cat > FILE.txt <<EOF
or cat >> FILE.txt <<EOF
make use of the same redirection operators, but add another layer via "Here Documents". In the above syntax, you write to the FILE.txt via the output of cat
. The writing only takes place after the interactive input is given some specific string, in this case 'EOF', but this could be any string, e.g.:
cat > FILE.txt <<'StopEverything'
or cat >> FILE.txt <<'StopEverything'
would work just as well. Here Documents also look for various delimiters and other interesting parsing characters, so have a look at the docs for further info on that.
A bit convoluted, and more of an exercise in understanding both redirection and Here Documents syntax, but you could combine Here Document style syntax with standard redirect operators to become a Here String:
Redirecting Output of cat Inputcat > myfile <<<'text to completely overwrite contents of myfile'
cat >> myfile <<<'text to completely overwrite contents of myfile'
For anyone who comes here, as I did, looking for the syntax to change origin to a different location you can find that documentation here: https://help.github.com/articles/changing-a-remote-s-url/. Using git remote add
to do this will result in "fatal: remote origin already exists."
Nutshell:
git remote set-url origin https://github.com/username/repo
(The marked answer is correct, I'm just hoping to help anyone as lost as I was... haha)
I needed to ensure values can still be entered with a comma instead of a point as a decimal separator. This seems to be an age-old problem. Background info can be found following these links:
I finally solved it with a little bit of jQuery. Replacing the commas with dots onChange. This seems to be working good so far in latest Firefox, Chrome and Safari.
$('input[type=number]').each(function () {
$(this).change(function () {
var $replace = $(this).val().toString().replace(/,/g, '.');

redis-cli -h XXX.XXX.XXX.XXX -p YYYY
xxx.xxx.xxx.xxx
is the IP address and yyyy
is the port
EXAMPLE from my dev environment
redis-cli -h 10.144.62.3 -p 30000
Host, port, password and database By default redis-cli connects to the server at 127.0.0.1 port 6379. As you can guess, you can easily change this using command line options. To specify a different host name or an IP address, use -h. In order to set a different port, use -p.
redis-cli -h redis15.localnet.org -p 6390 ping
You can use Func<T, TResult>
generic delegate. (See MSDN)
Func<MyType, ReturnType> func = (db) => { return new MyType(); }
Also there are useful generic delegates which considers a return value:
Method:
public MyType SimpleUsing.DoUsing<MyType>(Func<TInput, MyType> myTypeFactory)
Generic delegate:
Func<InputArgumentType, MyType> createInstance = db => return new MyType();
Execute:
MyType myTypeInstance = SimpleUsing.DoUsing(
createInstance(new InputArgumentType()));
OR explicitly:
MyType myTypeInstance = SimpleUsing.DoUsing(db => return new MyType());
Create two dates: one in June, one in January. Compare their getTimezoneOffset()
values.
Now check getTimezoneOffset()
of the current date.
The following snippets test for the "not contains" condition, as exemplified in the sample pseudocode in the question. For a direct solution with explicit looping, do this:
boolean contains = false;
for (char c : charArray) {
if (c == 'q') {
contains = true;
break;
}
}
if (!contains) {
// do something
}
Another alternative, using the fact that String
provides a contains()
method:
if (!(new String(charArray).contains("q"))) {
// do something
}
Yet another option, this time using indexOf()
:
if (new String(charArray).indexOf('q') == -1) {
// do something
}
//create TreeMap instance
TreeMap treeMap = new TreeMap();
//add key value pairs to TreeMap
treeMap.put("1","One");
treeMap.put("2","Two");
treeMap.put("3","Three");
/*
get Collection of values contained in TreeMap using
Collection values()
*/
Collection c = treeMap.values();
//obtain an Iterator for Collection
Iterator itr = c.iterator();
//iterate through TreeMap values iterator
while(itr.hasNext())
System.out.println(itr.next());
or:
for (Map.Entry<K,V> entry : treeMap.entrySet()) {
V value = entry.getValue();
K key = entry.getKey();
}
or:
// Use iterator to display the keys and associated values
System.out.println("Map Values Before: ");
Set keys = map.keySet();
for (Iterator i = keys.iterator(); i.hasNext();) {
Integer key = (Integer) i.next();
String value = (String) map.get(key);
System.out.println(key + " = " + value);
}
You can also perform Implicit Type Conversions with template literals. Example:
let fruits = ["mango","orange","pineapple","papaya"];
console.log(`My favourite fruits are ${fruits}`);
// My favourite fruits are mango,orange,pineapple,papaya
Working example with receiver (the top answer was just with action).
//starting
AlarmManager alarmManager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getActivity(), MyReceiver.class);
intent.setAction(MyReceiver.ACTION_ALARM_RECEIVER);//my custom string action name
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), 1001, intent, PendingIntent.FLAG_CANCEL_CURRENT);//used unique ID as 1001
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), aroundInterval, pendingIntent);//first start will start asap
//and stopping
Intent intent = new Intent(getActivity(), MyReceiver.class);//the same as up
intent.setAction(MyReceiver.ACTION_ALARM_RECEIVER);//the same as up
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), 1001, intent, PendingIntent.FLAG_CANCEL_CURRENT);//the same as up
alarmManager.cancel(pendingIntent);//important
pendingIntent.cancel();//important
//checking if alarm is working with pendingIntent
Intent intent = new Intent(getActivity(), MyReceiver.class);//the same as up
intent.setAction(MyReceiver.ACTION_ALARM_RECEIVER);//the same as up
boolean isWorking = (PendingIntent.getBroadcast(getActivity(), 1001, intent, PendingIntent.FLAG_NO_CREATE) != null);//just changed the flag
Log.d(TAG, "alarm is " + (isWorking ? "" : "not") + " working...");
It is worth to mention:
If the creating application later (process) re-retrieves the same kind of PendingIntent (same operation, same Intent's - action, data, categories, components, flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it.
In short, your PendingIntent should have the same features (operation and intent's structure) to take control over it.
if(arrayName.length > index && arrayName[index] !== null) {
//arrayName[index] has a value
}
there you go
$date = "04-15-2013";
$date1 = str_replace('-', '/', $date);
$tomorrow = date('m-d-Y',strtotime($date1 . "+1 days"));
echo $tomorrow;
this will output
04-16-2013
whilst sometimes you might have multiple php versions, you might also have a held-back version of php-mysql.. do a sudo dpkg -l | grep mysql | grep php and compare what you get from php -v
This is what I tried for a right outer join [as per my requirement]:
m1 <- merge(x=companies, y=rounds2, by.x=companies$permalink,
by.y=rounds2$company_permalink, all.y=TRUE)
# Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns
m1 <- merge(x=companies, y=rounds2, by.x=c("permalink"),
by.y=c("company_permalink"), all.y=TRUE)
This worked.
I know this is an ancient question, but I just thought that I'd weigh in.
I'm using disableScroll. Simple and it works like in a dream.
I have had some trouble disabling scroll on body, but allowing it on child elements (like a modal or a sidebar). It looks like that something can be done using disableScroll.on([element], [options]);
, but I haven't gotten that to work just yet.
The reason that this is prefered compared to overflow: hidden;
on body is that the overflow-hidden can get nasty, since some things might add overflow: hidden;
like this:
... This is good for preloaders and such, since that is rendered before the CSS is finished loading.
But it gives problems, when an open navigation should add a class to the body
-tag (like <body class="body__nav-open">
). And then it turns into one big tug-of-war with overflow: hidden; !important
and all kinds of crap.
@Navaneeth and @Antfish, no need to transform you can do like this also because in above solution only top border is visible so for inside curve you can use bottom border.
.box {_x000D_
width: 500px;_x000D_
height: 100px;_x000D_
border: solid 5px #000;_x000D_
border-color: transparent transparent #000 transparent;_x000D_
border-radius: 0 0 240px 50%/60px;_x000D_
}
_x000D_
<div class="box"></div>
_x000D_
To convert an int
ASCII value to character you can also use:
int asciiValue = 65;
char character = char(asciiValue);
cout << character; // output: A
cout << char(90); // output: Z

If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide()
, with additional arguments, as follows:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this).hide('slide',{direction:'right'},1000);
});
});
Without using jQuery UI, you could achieve your aim just using animate()
:
$(document).ready(
function(){
$('#slider').click(
function(){
$(this)
.animate(
{
'margin-left':'1000px'
// to move it towards the right and, probably, off-screen.
},1000,
function(){
$(this).slideUp('fast');
// once it's finished moving to the right, just
// removes the the element from the display, you could use
// `remove()` instead, or whatever.
}
);
});
});
If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js
onclick = "setTimeout(function() { document.getElementById('div1').style.display='none';document.getElementById('div2').style.display='none'}, 1000)"
Change 1000 to the number of milliseconds you want to delay.
VisualVm does not come with Apple JDK. You can use VisualVM Mac Application bundle(dmg) as a separate application, to compensate for that.
You can use the -TotalCount
parameter of the Get-Content
cmdlet to read the first n
lines, then use Select-Object
to return only the n
th line:
Get-Content file.txt -TotalCount 9 | Select-Object -Last 1;
Per the comment from @C.B. this should improve performance by only reading up to and including the n
th line, rather than the entire file. Note that you can use the aliases -First
or -Head
in place of -TotalCount
.
Try like
HTML in PHP :
echo "<a href='".$link_address."'>Link</a>";
Or even you can try like
echo "<a href='$link_address'>Link</a>";
Or you can use PHP in HTML like
PHP in HTML :
<a href="<?php echo $link_address;?>"> Link </a>
This error message can also be caused by SELinux. Check if SELinux is enabled with getenforce
You need to adjust SELinux to use your port and restart.

I had this issue also, I solved it instantly with this answer from a similar thread
In my case, I didn't want to delete the dependent record on key deletion. If this is the case in your situation just simply change the Boolean value in the migration to false:
AddForeignKey("dbo.Stories", "StatusId", "dbo.Status", "StatusID", cascadeDelete: false);
Chances are, if you are creating relationships which throw this compiler error but DO want to maintain cascade delete; you have an issue with your relationships.
I have an extension method for Uri that:
uri.WithQuery(new { name = "value" })
string/string
pairs (e.g. Dictionary`2).string/object
pairs (e.g. RouteValueDictionary).The documented version can be found here.
The extension:
public static Uri WithQuery(this Uri uri, object values)
{
if (uri == null)
throw new ArgumentNullException(nameof(uri));
if (values != null)
{
var query = string.Join(
"&", from p in ParseQueryValues(values)
where !string.IsNullOrWhiteSpace(p.Key)
let k = HttpUtility.UrlEncode(p.Key.Trim())
let v = HttpUtility.UrlEncode(p.Value)
orderby k
select string.IsNullOrEmpty(v) ? k : $"{k}={v}");
if (query.Length != 0 || uri.Query.Length != 0)
uri = new UriBuilder(uri) { Query = query }.Uri;
}
return uri;
}
The query parser:
private static IEnumerable<KeyValuePair<string, string>> ParseQueryValues(object values)
{
// Check if a name/value collection.
var nvc = values as NameValueCollection;
if (nvc != null)
return from key in nvc.AllKeys
from val in nvc.GetValues(key)
select new KeyValuePair<string, string>(key, val);
// Check if a string/string dictionary.
var ssd = values as IEnumerable<KeyValuePair<string, string>>;
if (ssd != null)
return ssd;
// Check if a string/object dictionary.
var sod = values as IEnumerable<KeyValuePair<string, object>>;
if (sod == null)
{
// Check if a non-generic dictionary.
var ngd = values as IDictionary;
if (ngd != null)
sod = ngd.Cast<dynamic>().ToDictionary<dynamic, string, object>(
p => p.Key.ToString(), p => p.Value as object);
// Convert object properties to dictionary.
if (sod == null)
sod = new RouteValueDictionary(values);
}
// Normalize and return the values.
return from pair in sod
from val in pair.Value as IEnumerable<string>
?? new[] { pair.Value?.ToString() }
select new KeyValuePair<string, string>(pair.Key, val);
}

You can simply use foreground for your View
to achieve clickable effect:
android:foreground="?android:attr/selectableItemBackground"
For use with dark theme add also theme to your layout
(to clickable effect be clear):
android:theme="@android:style/ThemeOverlay.Material.Dark"
allow_url_fopen
is generally set to On.
If it is not On, then you can try two things.
Create an .htaccess
file and keep it in root folder ( sometimes it may need to place it one step back folder of the root) and paste this code there.
php_value allow_url_fopen On
Create a php.ini
file (for update server php5.ini
) and keep it in root folder (sometimes it may need to place it one step back folder of the root) and paste the following code there:
allow_url_fopen = On;
I have personally tested the above solutions; they worked for me.
1) Go to teminal. open ~/.bashrc
. Add if not exists
if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi
2) open ~/.bash_aliases
. If not exists: touch ~/.bash_aliases && open ~/.bash_aliases
3) To add new alias rather
- edit .bash_aliases
file and restart terminal or print source ~/.bash_aliases
- print echo "alias clr='clear'" >> ~/.bash_aliases && source ~/.bash_aliases
where your alias is alias clr='clear'
.
4) Add line source ~/.bash_aliases
to ~/.bash_profile
file. It needs to load aliases in each init of terminal.
mute=1
or muted=1
as suggested by @Fab will work. However, if you wish to enable autoplay with sound you should add allow="autoplay"
to your embedded <iframe>
.
<iframe type="text/html" src="https://www.youtube.com/embed/-ePDPGXkvlw?autoplay=1" frameborder="0" allow="autoplay"></iframe>
This is officially supported and documented in Google's Autoplay Policy Changes 2017 post
Iframe delegation A feature policy allows developers to selectively enable and disable use of various browser features and APIs. Once an origin has received autoplay permission, it can delegate that permission to cross-origin iframes with a new feature policy for autoplay. Note that autoplay is allowed by default on same-origin iframes.
<!-- Autoplay is allowed. --> <iframe src="https://cross-origin.com/myvideo.html" allow="autoplay"> <!-- Autoplay and Fullscreen are allowed. --> <iframe src="https://cross-origin.com/myvideo.html" allow="autoplay; fullscreen">
When the feature policy for autoplay is disabled, calls to play() without a user gesture will reject the promise with a NotAllowedError DOMException. And the autoplay attribute will also be ignored.
use nth-child(item number) EX
<div class="parent_class">
<div class="myclass">my text1</div>
some other code+containers...
<div class="myclass">my text2</div>
some other code+containers...
<div class="myclass">my text3</div>
some other code+containers...
</div>
.parent_class:nth-child(1) { };
.parent_class:nth-child(2) { };
.parent_class:nth-child(3) { };
OR
:nth-of-type(item number) same your code
.myclass:nth-of-type(1) { };
.myclass:nth-of-type(2) { };
.myclass:nth-of-type(3) { };
This works for me
created a package called logger.go
package logger
import (
"flag"
"os"
"log"
"go/build"
)
var (
Log *log.Logger
)
func init() {
// set location of log file
var logpath = build.Default.GOPATH + "/src/chat/logger/info.log"
flag.Parse()
var file, err1 = os.Create(logpath)
if err1 != nil {
panic(err1)
}
Log = log.New(file, "", log.LstdFlags|log.Lshortfile)
Log.Println("LogFile : " + logpath)
}
import the package wherever you want to log e.g main.go
package main
import (
"logger"
)
const (
VERSION = "0.13"
)
func main() {
// time to use our logger, print version, processID and number of running process
logger.Log.Printf("Server v%s pid=%d started with processes: %d", VERSION, os.Getpid(),runtime.GOMAXPROCS(runtime.NumCPU()))
}
Declare an output cursor variable to the inner sp :
@c CURSOR VARYING OUTPUT
Then declare a cursor c to the select you want to return. Then open the cursor. Then set the reference:
DECLARE c CURSOR LOCAL FAST_FORWARD READ_ONLY FOR
SELECT ...
OPEN c
SET @c = c
DO NOT close or reallocate.
Now call the inner sp from the outer one supplying a cursor parameter like:
exec sp_abc a,b,c,, @cOUT OUTPUT
Once the inner sp executes, your @cOUT
is ready to fetch. Loop and then close and deallocate.
Both do the same work as they are used for routing purposes in SPA(Single Page Application).
URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.
HTML
<div ng-view></div>
Above tag will render the template from the $routeProvider.when()
condition which you had mentioned in .config
(configuration phase) of angular
Limitations:-
ng-view
on page$routeProvider
fails. (to achieve that, we need to use directives like ng-include
, ng-switch
, ng-if
, ng-show
, which looks bad to have them in SPA)AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.
Multiple & Named Views
Another great feature is the ability to have multiple ui-views in a template.
While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your view
s, and pairing those views with nested states.
HTML
<div ui-view>
<div ui-view='header'></div>
<div ui-view='content'></div>
<div ui-view='footer'></div>
</div>
The majority of ui-router
's power is it can manage nested state & views.
Pros
ui-view
on single pageui-view="some"
of state just by using absolute routing using @
with state name.@
to change ui-view="some"
. This will replace the ui-view
rather than checking if it is nested or not.ui-sref
to create a href
URL dynamically on the basis of URL
mentioned in a state, also you could give a state params in the json
format.For more Information Angular ui-router
For better flexibility with various nested view with states, I'd prefer you to go for ui-router
In addition to the above, I would like to point out that client-side validation (HTML code, javascript, etc.) is never enough. Also check the length server-side, or just don't check at all (if it's not so important that people can be allowed to get around it, then it's not important enough to really warrant any steps to prevent that, either).
Also, fellows, he (or she) said HTML, not XHTML. ;)
Just a small side-note... If you are using this with other scripts, the $ on the last line will cause a conflict. Just replace it with jQuery and you're good.
jQuery(function(){
jQuery('#showall').click(function(){
jQuery('.targetDiv').show();
});
jQuery('.showSingle').click(function(){
jQuery('.targetDiv').hide();
jQuery('#div'+jQuery(this).attr('target')).show();
});
});
This one work for me , first you bind datepicker to text-box and in next line set (today as default date) the date to it
$("#date").datepicker();
$("#date").datepicker("setDate", new Date());

Awesome tool!
Yes, rightly said. Hive does not support UPDATE option. But the following alternative could be used to achieve the result:
Update records in a partitioned Hive table
:
Join the two tables (main & staging tables) using a LEFT OUTER JOIN
operation as below:
insert overwrite table main_table partition (c,d)
select t2.a, t2.b, t2.c,t2.d from staging_table t2 left outer join main_table t1 on t1.a=t2.a;
In the above example, the main_table
& the staging_table
are partitioned using the (c,d)
keys. The tables are joined via a LEFT OUTER JOIN
and the result is used to OVERWRITE
the partitions in the main_table
.
A similar approach could be used in the case of un-partitioned Hive table
UPDATE
operations too.
You could refer to column alias but you need to define it using CROSS/OUTER APPLY
:
SELECT s.logcount, s.logUserID, s.maxlogtm, c.daysdiff
FROM statslogsummary s
CROSS APPLY (SELECT DATEDIFF(day, s.maxlogtm, GETDATE()) AS daysdiff) c
WHERE c.daysdiff > 120;
Pros:
WHERE/GROUP BY/ORDER BY
The error is:
Can not deserialize instance of java.lang.String out of START_ARRAY token at [Source: line: 1, column: 1095] (through reference chain: JsonGen["platforms"])
In JSON, platforms
look like this:
"platforms": [
{
"platform": "iphone"
},
{
"platform": "ipad"
},
{
"platform": "android_phone"
},
{
"platform": "android_tablet"
}
]
So try change your pojo to something like this:
private List platforms;
public List getPlatforms(){
return this.platforms;
}
public void setPlatforms(List platforms){
this.platforms = platforms;
}
EDIT: you will need change mobile_networks
too. Will look like this:
private List mobile_networks;
public List getMobile_networks() {
return mobile_networks;
}
public void setMobile_networks(List mobile_networks) {
this.mobile_networks = mobile_networks;
}

Sorry but vim don't work that way.
You should switch to "normal" mode, navigate and then go back to insert again.
You can try element[0].scrollTop, in my opinion this solution is faster.
Here you have bigger example - http://cvmlrobotics.blogspot.de/2013/03/angularjs-get-element-offset-position.html
Define "First"? If the table has a PK then it will be ordered by that, and you can delete by that:
DECLARE @TABLE TABLE
(
ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
Data NVARCHAR(50) NOT NULL
)
INSERT INTO @TABLE(Data)
SELECT 'Hello' UNION
SELECT 'World'
SET ROWCOUNT 1
DELETE FROM @TABLE
SET ROWCOUNT 0
SELECT * FROM @TABLE
If the table has no PK, then ordering won't be guaranteed...
Modifying Jeff's answer for optimal performance (thanks to performance test by Pierre Arnaud):
var type = typeof(MyType);
var implementsInterface = typeof(IMyInterface).IsAssignableFrom(type) && type.IsClass;
To find all types that implement an interface in a given Assembly
:
var implementations = typeof(TypeInTargetAssembly).Assembly.GetTypes()
.Where(t => typeof(IMyInterface).IsAssignableFrom(t) && t.IsClass);

For Oracle versions which does not support the WM_CONCAT, the following can be used
select "User", RTRIM(
XMLAGG (XMLELEMENT(e, department||',') ORDER BY department).EXTRACT('//text()') , ','
) AS departments
from yourtable
group by "User"
This one is much more powerful and flexible - you can specify both delimiters and sort order within each group as in listagg.
There is a simple example of convert enumeration to list. for this i used Collections.list(enum)
method.
public class EnumerationToList {
public static void main(String[] args) {
Vector<String> vt = new Vector<String>();
vt.add("java");
vt.add("php");
vt.add("array");
vt.add("string");
vt.add("c");
Enumeration<String> enm = vt.elements();
List<String> ll = Collections.list(enm);
System.out.println("List elements: " + ll);
}
}

In addition Swiss Mister post, in my case the window.open was launched inside a promise, which turned the popup blocker on, my solution was: in angular:
$scope.gotClick = function(){
var myNewTab = browserService.openNewTab();
someService.getUrl().then(
function(res){
browserService.updateTabLocation(res.url, myNewTab);
}
);
};
browserService:
this.openNewTab = function(){
var newTabWindow = $window.open();
return newTabWindow;
}
this.updateTabLocation = function(tabLocation, tab) {
if(!tabLocation){
tab.close();
}
tab.location.href = tabLocation;
}
this is how you can open a new tab using the promise response and not invoking the popup blocker.
Run CMD as administrator
and on CMD screen type ipconfig and the screen will appear with text
as this photo
and you can access your localhost using this ip you have to be connected to same network as your pc connected to
You can use
var mystr = "Doe";
mystr = "John " + mystr;
console.log(mystr)
Alternatively, you could just return false from the click event:
$('div.toggle').hide();
$('ul.product-info li a').click(function(event){
$(this).next('div').slideToggle(200);
+ return false;
});
Which would stop the A-Href being triggered.
Note however, for usability reasons, in an ideal world that href should still go somewhere, for the people whom want to open link in new tab ;)
I had the same issue when I was using GIT bash to merge master branch in to my feature branch. I followed the following steps to overcome this.
My advice is to stick to rule 0 and not redo what standard libraries already do, if this is enough. Look at math.h (cmath in standard C++) and functions frexp, frexpf, frexpl, that break a floating point value (double, float, or long double) in its significand and exponent part. To extract the sign from the significand you can use signbit, also in math.h / cmath, or copysign (only C++11). Some alternatives, with slighter different semantics, are modf and ilogb/scalbn, available in C++11; http://en.cppreference.com/w/cpp/numeric/math/logb compares them, but I didn't find in the documentation how all these functions behave with +/-inf and NaNs. Finally, if you really want to use bitmasks (e.g., you desperately need to know the exact bits, and your program may have different NaNs with different representations, and you don't trust the above functions), at least make everything platform-independent by using the macros in float.h/cfloat.
To obtain readable x tick labels without additional dependencies, you want to use:
... +
theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5)) +
...
This rotates the tick labels 90° counterclockwise and aligns them vertically at their end (hjust = 1
) and their centers horizontally with the corresponding tick mark (vjust = 0.5
).
Full example:
library(ggplot2)
data(diamonds)
diamonds$cut <- paste("Super Dee-Duper",as.character(diamonds$cut))
q <- qplot(cut,carat,data=diamonds,geom="boxplot")
q + theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))
Note, that vertical/horizontal justification parameters vjust
/hjust
of element_text
are relative to the text. Therefore, vjust
is responsible for the horizontal alignment.
Without vjust = 0.5
it would look like this:
q + theme(axis.text.x = element_text(angle = 90, hjust = 1))
Without hjust = 1
it would look like this:
q + theme(axis.text.x = element_text(angle = 90, vjust = 0.5))
If for some (wired) reason you wanted to rotate the tick labels 90° clockwise (such that they can be read from the left) you would need to use: q + theme(axis.text.x = element_text(angle = -90, vjust = 0.5, hjust = -1))
.
All of this has already been discussed in the comments of this answer but I come back to this question so often, that I want an answer from which I can just copy without reading the comments.
Find the text nodes (nodeType==3
) and replace the textContent
:
$('#one').contents().filter(function() {
return this.nodeType == 3
}).each(function(){
this.textContent = this.textContent.replace('Hi I am text','Hi I am replace');
});
Note that as per the docs you can replace the hard-coded 3
in the above with Node.TEXT_NODE
which is much clearer what you're doing.
$('#one').contents().filter(function() {
return this.nodeType == Node.TEXT_NODE;
}).each(function(){
this.textContent = this.textContent.replace('Hi I am text','Hi I am replace');
});

Here's an example using IterableDiffer with ngDoCheck. IterableDiffer is especially useful if you need to track changes over time as it lets you do things like iterate over only added/changed/removed values etc.
A simple example not using all advantages of IterableDiffer, but it works and shows the principle:
export class FeedbackMessagesComponent implements DoCheck {
@Input()
messages: UserFeedback[] = [];
// Example UserFeedback instance { message = 'Ooops', type = Notice }
@HostBinding('style.display')
display = 'none';
private _iterableDiffer: IterableDiffer<UserFeedback>;
constructor(private _iterableDiffers: IterableDiffers) {
this._iterableDiffer = this._iterableDiffers.find([]).create(null);
}
ngDoCheck(): void {
const changes = this._iterableDiffer.diff(this.messages);
if (changes) {
// Here you can do stuff like changes.forEachRemovedItem()
// We know contents of this.messages was changed so update visibility:
this.display = this.messages.length > 0 ? 'block' : 'none';
}
}
}
This will now automatically show/hide depending on myMessagesArray count:
<app-feedback-messages
[messages]="myMessagesArray"
></app-feedback-messages>

Since you're using gensim, you should probably use it's doc2vec implementation. doc2vec is an extension of word2vec to the phrase-, sentence-, and document-level. It's a pretty simple extension, described here
http://cs.stanford.edu/~quocle/paragraph_vector.pdf
Gensim is nice because it's intuitive, fast, and flexible. What's great is that you can grab the pretrained word embeddings from the official word2vec page and the syn0 layer of gensim's Doc2Vec model is exposed so that you can seed the word embeddings with these high quality vectors!
GoogleNews-vectors-negative300.bin.gz (as linked in Google Code)
I think gensim is definitely the easiest (and so far for me, the best) tool for embedding a sentence in a vector space.
There exist other sentence-to-vector techniques than the one proposed in Le & Mikolov's paper above. Socher and Manning from Stanford are certainly two of the most famous researchers working in this area. Their work has been based on the principle of compositionally - semantics of the sentence come from:
1. semantics of the words
2. rules for how these words interact and combine into phrases
They've proposed a few such models (getting increasingly more complex) for how to use compositionality to build sentence-level representations.
2011 - unfolding recursive autoencoder (very comparatively simple. start here if interested)
2012 - matrix-vector neural network
2013 - neural tensor network
2015 - Tree LSTM
his papers are all available at socher.org. Some of these models are available, but I'd still recommend gensim's doc2vec. For one, the 2011 URAE isn't particularly powerful. In addition, it comes pretrained with weights suited for paraphrasing news-y data. The code he provides does not allow you to retrain the network. You also can't swap in different word vectors, so you're stuck with 2011's pre-word2vec embeddings from Turian. These vectors are certainly not on the level of word2vec's or GloVe's.
Haven't worked with the Tree LSTM yet, but it seems very promising!
tl;dr Yeah, use gensim's doc2vec. But other methods do exist!
Do you need a type attribute at all? If you're using HTML5, no. Otherwise, yes. HTML 4.01 and XHTML 1.0 specifies the type
attribute as required while HTML5 has it as optional, defaulting to text/javascript
. HTML5 is now widely implemented, so if you use the HTML5 doctype, <script>...</script>
is valid and a good choice.
As to what should go in the type attribute, the MIME type application/javascript
registered in 2006 is intended to replace text/javascript
and is supported by current versions of all the major browsers (including Internet Explorer 9). A quote from the relevant RFC:
This document thus defines text/javascript and text/ecmascript but marks them as "obsolete". Use of experimental and unregistered media types, as listed in part above, is discouraged. The media types,
* application/javascript * application/ecmascript
which are also defined in this document, are intended for common use and should be used instead.
However, IE up to and including version 8 doesn't execute script inside a <script>
element with a type
attribute of either application/javascript
or application/ecmascript
, so if you need to support old IE, you're stuck with text/javascript
.
You can configure the connect body parser middleware in a configuration block in your main application file:
/** Form Handling */
app.use(express.bodyParser({
uploadDir: '/tmp/uploads',
keepExtensions: true
}))
app.use(express.limit('5mb'));
Here's the answer of your 2nd question :

Where netDateTime
is your DateTime variable serialized, something like "/Date(1456956000000+0200)/"

Think about this from an aspect-oriented point of view; what you want to do, really, is know all the classes at runtime that HAVE extended the Animal class. (I think that's a slightly more accurate description of your problem than your title; otherwise, I don't think you have a runtime question.)
So what I think you want is to create a constructor of your base class (Animal) which adds to your static array (I prefer ArrayLists, myself, but to each their own) the type of the current Class which is being instantiated.
So, roughly;
public abstract class Animal
{
private static ArrayList<Class> instantiatedDerivedTypes;
public Animal() {
Class derivedClass = this.getClass();
if (!instantiatedDerivedClass.contains(derivedClass)) {
instantiatedDerivedClass.Add(derivedClass);
}
}
Of course, you'll need a static constructor on Animal to initialize instantiatedDerivedClass... I think this'll do what you probably want. Note that this is execution-path dependent; if you have a Dog class that derives from Animal that never gets invoked, you won't have it in your Animal Class list.

If you know a .NET language (C#/VB.NET etc) then checkout VST.NET. This framework allows you to create (unmanaged) VST 2.4 plugins in .NET. It comes with a framework that structures and simplifies the creation of a VST Plugin with support for Parameters, Programs and Persistence.
There are several samples that demonstrate the typical plugin scenarios. There's also documentation that explains how to get started and some of the concepts behind VST.NET.

Take advantage of the standard char_traits
. Recall that a std::string
is in fact a typedef for std::basic_string<char>
, or more explicitly, std::basic_string<char, std::char_traits<char> >
. The char_traits
type describes how characters compare, how they copy, how they cast etc. All you need to do is typedef a new string over basic_string
, and provide it with your own custom char_traits
that compare case insensitively.
struct ci_char_traits : public char_traits<char> {
static bool eq(char c1, char c2) { return toupper(c1) == toupper(c2); }
static bool ne(char c1, char c2) { return toupper(c1) != toupper(c2); }
static bool lt(char c1, char c2) { return toupper(c1) < toupper(c2); }
static int compare(const char* s1, const char* s2, size_t n) {
while( n-- != 0 ) {
if( toupper(*s1) < toupper(*s2) ) return -1;
if( toupper(*s1) > toupper(*s2) ) return 1;
++s1; ++s2;
}
return 0;
}
static const char* find(const char* s, int n, char a) {
while( n-- > 0 && toupper(*s) != toupper(a) ) {
++s;
}
return s;
}
};

I created a reusable Angular service to handle high quality resizing of images / canvases for anyone who's interested: https://gist.github.com/transitive-bullshit/37bac5e741eaec60e983
The service includes two solutions because they both have their own pros / cons. The lanczos convolution approach is higher quality at the cost of being slower, whereas the step-wise downscaling approach produces reasonably antialiased results and is significantly faster.
Example usage:
angular.module('demo').controller('ExampleCtrl', function (imageService) {
// EXAMPLE USAGE
// NOTE: it's bad practice to access the DOM inside a controller,
// but this is just to show the example usage.
// resize by lanczos-sinc filter
imageService.resize($('#myimg')[0], 256, 256)
.then(function (resizedImage) {
// do something with resized image
})
// resize by stepping down image size in increments of 2x
imageService.resizeStep($('#myimg')[0], 256, 256)
.then(function (resizedImage) {
// do something with resized image
})
})
if (StringA.ToUpperInvariant() == StringB.ToUpperInvariant()) {
People report ToUpperInvariant() is faster than ToLowerInvariant().

Using getView()
returns the view of the fragment, then you can call findViewById()
to access any view element in the fragment view.
To add to Lennart Regebro's answer There is even the third way that can be used:
encoded3 = str.encode(original, 'utf-8')
print(encoded3)
Anyway, it is actually exactly the same as the first approach. It may also look that the second way is a syntactic sugar for the third approach.
A programming language is a means to express abstract ideas formally, to be executed by the machine. A programming language is considered good if it contains constructs that one needs. Python is a hybrid language -- i.e. more natural and more versatile than pure OO or pure procedural languages. Sometimes functions are more appropriate than the object methods, sometimes the reverse is true. It depends on mental picture of the solved problem.
Anyway, the feature mentioned in the question is probably a by-product of the language implementation/design. In my opinion, this is a nice example that show the alternative thinking about technically the same thing.
In other words, calling an object method means thinking in terms "let the object gives me the wanted result". Calling a function as the alternative means "let the outer code processes the passed argument and extracts the wanted value".
The first approach emphasizes the ability of the object to do the task on its own, the second approach emphasizes the ability of an separate algoritm to extract the data. Sometimes, the separate code may be that much special that it is not wise to add it as a general method to the class of the object.

The whole point of HttpOnly cookies is that they can't be accessed by JavaScript.
The only way (except for exploiting browser bugs) for your script to read them is to have a cooperating script on the server that will read the cookie value and echo it back as part of the response content. But if you can and would do that, why use HttpOnly cookies in the first place?

One Way to solve this problem is, push the negative of each element in the priority_queue so the largest element will become the smallest element. At the time of making pop operation, take the negation of each element.
#include<bits/stdc++.h>
using namespace std;
int main(){
priority_queue<int> pq;
int i;
// push the negative of each element in priority_queue, so the largest number will become the smallest number
for (int i = 0; i < 5; i++)
{
cin>>j;
pq.push(j*-1);
}
for (int i = 0; i < 5; i++)
{
cout<<(-1)*pq.top()<<endl;
pq.pop();
}
}
Using .Equals is also a lot easier to read.
This is an interesting variation on the theme. At first and second glances you would assume the true branch is taken. Not so!

The way to get what you want is to do this:
if (!(flag ?? true))
{
// false branch
}
else
{
// true branch

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.
Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE
so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.
also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

Yes, standard behaviour is the value is only sent if the checkbox is checked. This typically means you need to have a way of remembering what checkboxes you are expecting on the server side since not all the data comes back from the form.
The default value is always "on", this should be consistent across browsers.
This is covered in the W3C HTML 4 recommendation:
Checkboxes (and radio buttons) are on/off switches that may be toggled by the user. A switch is "on" when the control element's checked attribute is set. When a form is submitted, only "on" checkbox controls can become successful.

I had some problems with Xcode 5.1 crashing on me, when I opened the doc window.
I am not sure of the cause of it, because I was also updating docsets, while I opened the window.
Well, in Xcode 5 the modules directory now resides within the derived data folder, which I for obvious reasons didn't delete. I deleted the contents of ~/Library/Developer/Xcode/DerivedData/ModuleCache and the ~/Library/Preferences/com.apple.Xcode.plist and everything then seems to work, after I restarted Xcode.
Mota's answer is great unless your BufferedImage came from a Monochrome Bitmap. A Monochrome Bitmap has only 2 possible values for its pixels (for example 0 = black and 1 = white). When a Monochrome Bitmap is used then the
final byte[] pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();
call returns the raw Pixel Array data in such a fashion that each byte contains more than one pixel.
So when you use a Monochrome Bitmap image to create your BufferedImage object then this is the algorithm you want to use:
/**
* This returns a true bitmap where each element in the grid is either a 0
* or a 1. A 1 means the pixel is white and a 0 means the pixel is black.

SQL is the actual language that as defined by the ISO and ANSI. Here is a link to the Wikipedia article. MySQL is a specific implementation of this standard. I believe Oracle bought the company that originally developed MySQL. Other companies also have their own implementations of the SQL standard.
Old question but I upgrade the answers supporting Android prior and post 4.2 and considering all recent changes according to Android developers blog

To answer your question, yes you may pass JSON in the URI as part of a GET request (provided you URL-encode). However, considering your reason for doing this is due to the length of the URI, using JSON will be self-defeating (introducing more characters than required).
I suggest you send your parameters in body of a POST request, either in regular CGI style (param1=val1¶m2=val2
) or JSON (parsed by your API upon receipt)
My edit got rejected, so I'm attaching how to handle merging changes from a remote branch here.
If you have to do this after an incorrect merge, you can do something like this:
# If you did a git pull and it broke something, do this first
# Find the one before the merge, copy the SHA1
git reflog
git reset --hard <sha1>
# Get remote updates but DONT auto merge it
git fetch github
# Checkout to your mainline so your branch is correct.
git checkout develop
# Make a new branch where you'll be applying matches
git checkout -b manual-merge-github-develop
# Apply your patches
git checkout --patch github/develop path/to/file
...
# Merge changes back in
git checkout develop
git merge manual-merge-github-develop # optionally add --no-ff
# You'll probably have to
git push -f # make sure you know what you're doing.
What I use:
class Enum(object):
def __init__(self, names, separator=None):
self.names = names.split(separator)
for value, name in enumerate(self.names):
setattr(self, name.upper(), value)
def tuples(self):
return tuple(enumerate(self.names))
How to use:
>>> state = Enum('draft published retracted')
>>> state.DRAFT
0
>>> state.RETRACTED
2
>>> state.FOO
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Enum' object has no attribute 'FOO'
>>> state.tuples()
((0, 'draft'), (1, 'published'), (2, 'retracted'))
So this gives you integer constants like state.PUBLISHED and the two-tuples to use as choices in Django models.
With EF or LINQ to SQL:
var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();
With LINQ to Objects I suggest to use morelinq extension MaxBy
(get morelinq from nuget):
var item = items.MaxBy(i => i.Value);
Looks like TaskCache registry data is in ...
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache
... on my Windows 10 PC (i.e. add Schedule before TaskCache and TaskCache has an upper case C).
We had this in many other cases, what we decided internally is to always have a wrapper for the controller/directive so that we don't need to think about it. Here is you example with our wrapper.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular.min.js"></script>
<script>
function main($scope) {
$scope.thisScope = $scope;
$scope.testa = false;
$scope.testb = false;
$scope.testc = false;
$scope.testd = false;
}
</script>
<div ng-app >
<div ng-controller="main">
Test A: {{testa}}<br />
Test B: {{testb}}<br />
Test C: {{testc}}<br />
Test D: {{testd}}<br />
<div>
testa (without ng-if): <input type="checkbox" ng-model="thisScope.testa" />
</div>
<div ng-if="!testa">
testb (with ng-if): <input type="checkbox" ng-model="thisScope.testb" />

I got a simillary problem using unicode and fontawesome. when i wrote :
font-family: 'Font Awesome\ 5 Free';
content: "\f061"; /* FontAwesome Unicode */
On google chrome, a square appear instead of the icon. The new version of Font Awesome also requires
font-weight: 900;
That's work for me.
From : https://github.com/FortAwesome/Font-Awesome/issues/11946
Hope that's will help.
There are two ways to do this:
CSS: Use width as %, like 75%, so the width of the div will change automatically when user resizes the browser.
Javascipt: Use resize event
$(window).bind('resize', function()
{
if($(window).width() > 500)
$('#divID').css('width', '300px');
else
$('divID').css('width', '200px');
});
Hope this will help you :)
We need to wait for view will be drawn. For this purpose use OnPreDrawListener. Kotlin example:
val preDrawListener = object : ViewTreeObserver.OnPreDrawListener {
override fun onPreDraw(): Boolean {
view.viewTreeObserver.removeOnPreDrawListener(this)
// code which requires view size parameters
return true
}
}
view.viewTreeObserver.addOnPreDrawListener(preDrawListener)
Use the CATALINA_OPTS
environment variable.
Instead of
let loginRegisterButton:UIButton = {
//... }()
Try:
lazy var loginRegisterButton:UIButton = {
//... }()
That should fix the compile error!!!
You can use the sequence method list.extend
to extend the list by multiple values from any kind of iterable, being it another list or any other thing that provides a sequence of values.
>>> lst = [1, 2]
>>> lst.append(3)
>>> lst.append(4)
>>> lst
[1, 2, 3, 4]
>>> lst.extend([5, 6, 7])
>>> lst.extend((8, 9, 10))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
So you can use list.append()
to append a single value, and list.extend()
to append multiple values.
Here's Microsoft's write up on using SET IDENTITY_INSERT, which might be helpful to others seeing this post if they, like me, found this post when trying to recreate deleted records while maintaining the original identity column value.

There's also solution for Node JS app. CORS Anywhere is a NodeJS proxy which adds CORS headers to the proxied request.
The url to proxy is literally taken from the path, validated and proxied. The protocol part of the proxied URI is optional, and defaults to "http". If port 443 is specified, the protocol defaults to "https".
This package does not put any restrictions on the http methods or headers, except for cookies. Requesting user credentials is disallowed. The app can be configured to require a header for proxying a request, for example to avoid a direct visit from the browser. https://robwu.nl/cors-anywhere.html

One useful line of code for you would be:
$sql = "Your SQL statement here";
$result = mysqli_query($this->db_link, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($this->db_link), E_USER_ERROR);
This method is better than die
, because you can use it for development AND production. It's the permanent solution.
To find the minimum value of a list, you might just as well use min
:
x = min(float(s) for s in l) # min of a generator
Or, if you want the result as a string, rather than a float, use a key function:
x = min(l, key=float)
Thanks @John Leehey and @PeterH:
desiredSp = getResources().getDimension(R.dimen.desired_sp);
density = getResources().getDisplayMetrics().density;
textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, desiredSp / density);
The thing is if you define R.dimen.desired_sp to 25 in your dimen.xml

self.tableView.tableFooterView = UIView(frame: CGRectZero)
self.tableView.tableFooterView?.hidden = true
The second line of code does not cause any effect on presentation, you can use to check if is hidden or not.

Run the code snippet and see the variations. Here is note for quick understanding
Example 1(Object selection):- ng-option="os.name for os in osList track by os.id"
. Here track by os.id
is important & should be there and os.id as
should NOT have before os.name
.
ng-model="my_os"
should set to an object with key as id like my_os={id: 2}
.Example 2(Value selection) :- ng-option="os.id as os.name for os in osList"
. Here track by os.id
should NOT be there and os.id as
should be there before os.name
.
ng-model="my_os"
should set to a value like my_os= 2
Rest code snippet will explain.

I agree with Ed. C# does not make this easy the way VB does with ReDim Preserve. Without a collection, you'll have to copy the array into a larger one.
As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron
. Hence, do install it with:
yum install vixie-cron
And then start it with:
service crond start
To make it persistent, so that it starts on boot, use:
chkconfig crond on
On CentOS 7 you need to use cronie
:
yum install cronie
On CentOS 6 you can install vixie-cron
, but the real package is cronie
:
yum install vixie-cron
and
yum install cronie
In both cases you get the same output:

Create a drawable resource what background you need, in my case I named it bg_custom_progressbar.xml
<?xml version="1.0" encoding="utf-8"?>
<item>
<shape android:shape="rectangle" >
<corners android:radius="5dp"/>
<gradient
android:angle="180"
android:endColor="#DADFD6"
android:startColor="#AEB9A3" />
</shape>
</item>
<item>
<clip>
<shape android:shape="rectangle" >
<corners android:radius="5dp" />

<gradient
android:angle="180"
android:endColor="#44CF4A"
android:startColor="#2BB930" />
</shape>
</clip>
</item>
Then use this custom background like
<ProgressBar
android:id="@+id/progressBarBarMenuHome"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="20dp"
android:layout_marginStart="10dp"

android:layout_marginBottom="6dp"
android:indeterminate="false"
android:max="100"
android:minWidth="200dp"
android:minHeight="50dp"
android:progress="10"
android:progressDrawable="@drawable/bg_custom_progressbar" />
Its works fine for me
There is already an ISO standard for this; no need to invent your own scheme:
http://en.wikipedia.org/wiki/ISO_5218
Per the standard, the column should be called "Sex" and the 'closest' data type would be tinyint with a CHECK constraint or lookup table as appropriate.
I found this to accomplish the entire solution. The answer above fails to remove the window from the task bar.
private void ImportStatusForm_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
notifyIcon.Visible = true;
notifyIcon.ShowBalloonTip(3000);
this.ShowInTaskbar = false;
}
}
private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.WindowState = FormWindowState.Normal;
this.ShowInTaskbar = true;
notifyIcon.Visible = false;
}
Also it is good to set the following properties of the notify icon control using the forms designer.
this.notifyIcon.BalloonTipIcon = System.Windows.Forms.ToolTipIcon.Info; //Shows the info icon so the user doesn't think there is an error.
this.notifyIcon.BalloonTipText = "[Balloon Text when Minimized]";
this.notifyIcon.BalloonTipTitle = "[Balloon Title when Minimized]";
this.notifyIcon.Icon = ((System.Drawing.Icon)(resources.GetObject("notifyIcon.Icon"))); //The tray icon to use
this.notifyIcon.Text = "[Message shown when hovering over tray icon]";
If you have to run composer with sudo, you should change the directory of composer to
/usr/bin
this was tested on Centos8.
You can use jQuery's .is() function.
if ( $(".parent a").is("#idSelector") ) {
//Do stuff
}
It will return true if the parent anchor has #idSelector id.
print(', '.join(names))
This, like it sounds, just takes all the elements of the list and joins them with ', '
.
if (Enum.IsDefined(typeof(foo), value))
{
return (Foo)Enum.Parse(typeof(foo), value);
}
Hope this helps
Edit This answer got down voted as value in my example is a string, where as the question asked for an int. My applogies; the following should be a bit clearer :-)
Type fooType = typeof(foo);
if (Enum.IsDefined(fooType , value.ToString()))
{
return (Foo)Enum.Parse(fooType , value.ToString());
}
In your local system right,
go to this url : http://localhost/phpmyadmin/
In this click mysql default db, after that browser user table to get existing username and password.
The checked
attribute of an input type="checkbox"
is mapped with the defaultChecked
property, not with the checked
property.
So when doing something in a page when a checkbox is checked on uncheked, use the prop()
method instead. It fetches the property value and changes as the state of the checkbox changes.
Using attr(
) or getAttribute
(in pure JavaScript) in these cases are not the proper way of doing things.
if elem
is the concerned checkbox then do something like this to fetch the value:
elem.checked
or
$(elem).prop('checked')
you should use action instead of actionListener:
<h:commandLink id="close" action="#{bean.close}" value="Close" immediate="true"
/>
and in close method you right something like:
public String close() {
return "index?faces-redirect=true";
}
where index is one of your pages(index.xhtml)
Of course, all this staff should be written in our original page, not in the intermediate.
And inside the close()
method you can use the parameters to dynamically choose where to redirect.
I know that is a old question, but...
You can also use this in your class:
@Autowired
private HttpServletRequest context;
And this will provide the current instance of HttpServletRequest
for you use on your method.
you can use the left_on and right_on options as follows:
pd.merge(frame_1, frame_2, left_on='county_ID', right_on='countyid')
I was not sure from the question if you only wanted to merge if the key was in the left hand dataframe. If that is the case then the following will do that (the above will in effect do a many to many merge)
pd.merge(frame_1, frame_2, how='left', left_on='county_ID', right_on='countyid')
