There is also some more detail on the use of <mvc:annotation-driven />
in the Spring docs. In a nutshell, <mvc:annotation-driven />
gives you greater control over the inner workings of Spring MVC. You don't need to use it unless you need one or more of the features outlined in the aforementioned section of the docs.
Also, there are other "annotation-driven" tags available to provide additional functionality in other Spring modules. For example, <transaction:annotation-driven />
enables the use of the @Transaction annotation, <task:annotation-driven />
is required for @Scheduled et al...
<context:annotation-config>
: Scanning and activating annotations for already registered beans in spring config xml.
<context:component-scan>
: Bean registration + <context:annotation-config>
@Autowired and @Required are targets property level so bean should register in spring IOC before use these annotations. To enable these annotations either have to register respective beans or include <context:annotation-config />
. i.e. <context:annotation-config />
works with registered beans only.
@Required enables RequiredAnnotationBeanPostProcessor
processing tool
@Autowired enables AutowiredAnnotationBeanPostProcessor
processing tool
Note: Annotation itself nothing to do, we need a Processing Tool, which is a class underneath, responsible for the core process.
@Repository, @Service and @Controller are @Component, and they targets class level.
<context:component-scan>
it scans the package and find and register the beans, and it includes the work done by <context:annotation-config />
.
Using Accept header is really easy to get the format json or xml from the REST service.
This is my Controller, take a look produces section.
@RequestMapping(value = "properties", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.GET)
public UIProperty getProperties() {
return uiProperty;
}
In order to consume the REST service we can use the code below where header can be MediaType.APPLICATION_JSON_VALUE or MediaType.APPLICATION_XML_VALUE
HttpHeaders headers = new HttpHeaders();
headers.add("Accept", header);
HttpEntity entity = new HttpEntity(headers);
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties", HttpMethod.GET, entity,String.class);
return response.getBody();
Edit 01:
In order to work with application/xml
, add this dependency
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
To complete the answer from Sotorios Delimanolis.
It's true that ResponseEntity
gives you more flexibility but in most cases you won't need it and you'll end up with these ResponseEntity
everywhere in your controller thus making it difficult to read and understand.
If you want to handle special cases like errors (Not Found, Conflict, etc.), you can add a HandlerExceptionResolver
to your Spring configuration. So in your code, you just throw a specific exception (NotFoundException
for instance) and decide what to do in your Handler (setting the HTTP status to 404), making the Controller code more clear.
Nothing in the example says that the "classes implementing the same interface". MovieCatalog
is a type and CustomerPreferenceDao
is another type. Spring can easily tell them apart.
In Spring 2.x, wiring of beans mostly happened via bean IDs or names. This is still supported by Spring 3.x but often, you will have one instance of a bean with a certain type - most services are singletons. Creating names for those is tedious. So Spring started to support "autowire by type".
What the examples show is various ways that you can use to inject beans into fields, methods and constructors.
The XML already contains all the information that Spring needs since you have to specify the fully qualified class name in each bean. You need to be a bit careful with interfaces, though:
This autowiring will fail:
@Autowired
public void prepare( Interface1 bean1, Interface1 bean2 ) { ... }
Since Java doesn't keep the parameter names in the byte code, Spring can't distinguish between the two beans anymore. The fix is to use @Qualifier
:
@Autowired
public void prepare( @Qualifier("bean1") Interface1 bean1,
@Qualifier("bean2") Interface1 bean2 ) { ... }
Right after @mail($email_to, $email_subject, $email_message, $headers);
header('Location: nextpage.php');
Note that you will never see 'Thanks for subscribing to our mailing list'
That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!
Here are the ways to assign parent object in child object of Bi-directional relations ?
Suppose you have a relation say One-To-Many,then for each parent object,a set of child object exists. In bi-directional relations,each child object will have reference to its parent.
eg : Each Department will have list of Employees and each Employee is part of some department.This is called Bi directional relations.
To achieve this, one way is to assign parent in child object while persisting parent object
Parent parent = new Parent();
...
Child c1 = new Child();
...
c1.setParent(parent);
List<Child> children = new ArrayList<Child>();
children.add(c1);
parent.setChilds(children);
session.save(parent);
Other way is, you can do using hibernate Intercepter,this way helps you not to write above code for all models.
Hibernate interceptor provide apis to do your own work before perform any DB operation.Likewise onSave of object, we can assign parent object in child objects using reflection.
public class CustomEntityInterceptor extends EmptyInterceptor {
@Override
public boolean onSave(
final Object entity, final Serializable id, final Object[] state, final String[] propertyNames,
final Type[] types) {
if (types != null) {
for (int i = 0; i < types.length; i++) {
if (types[i].isCollectionType()) {
String propertyName = propertyNames[i];
propertyName = propertyName.substring(0, 1).toUpperCase() + propertyName.substring(1);
try {
Method method = entity.getClass().getMethod("get" + propertyName);
List<Object> objectList = (List<Object>) method.invoke(entity);
if (objectList != null) {
for (Object object : objectList) {
String entityName = entity.getClass().getSimpleName();
Method eachMethod = object.getClass().getMethod("set" + entityName, entity.getClass());
eachMethod.invoke(object, entity);
}
}
} catch (NoSuchMethodException | InvocationTargetException | IllegalAccessException e) {
throw new RuntimeException(e);
}
}
}
}
return true;
}
}
And you can register Intercepter to configuration as
new Configuration().setInterceptor( new CustomEntityInterceptor() );
Well one way to do it is set the height of your body to the height
that you want your page
to be. In this example I did 600px
.
Then set your wrapper
height to a percentage of the body here I did 70%
This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.
body {
padding-top: 70px;
border:1px solid black;
height:600px;
}
.mygrid-wrapper-div {
border: solid red 5px;
overflow: scroll;
height: 70%;
}
Update How about a jQuery approach.
$(function() {
var window_height = $(window).height(),
content_height = window_height - 200;
$('.mygrid-wrapper-div').height(content_height);
});
$( window ).resize(function() {
var window_height = $(window).height(),
content_height = window_height - 200;
$('.mygrid-wrapper-div').height(content_height);
});
This is the way I've done:
Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
MediaPlayer mp = MediaPlayer.create(getApplicationContext(), notification);
mp.start();
It is similar to markov00's way, but uses MediaPlayer instead of Ringtone which prevents interrupting other sounds, like music, that might already be playing in the background.
In the constructor of
public class ErrorEventArg : EventArgs
You have to add "base" as follows:
public ErrorEventArg(string errorMsg, string lastQuery) : base (string errorMsg, string lastQuery)
{
ErrorMsg = errorMsg;
LastQuery = lastQuery;
}
That solved it for me
pickBy uses identity by default:
_.pickBy({ a: null, b: 1, c: undefined, d: false });
If you're in the middle of a commit (i.e. in your editor already), you can cancel it by deleting all lines above the first #
. That will abort the commit.
So you can delete all lines so that the commit message is empty, then save the file:
You'll then get a message that says Aborting commit due to empty commit message.
.
EDIT:
You can also delete all the lines and the result will be exactly the same.
To delete all lines in vim (if that is your default editor), once you're in the editor, type gg
to go to the first line, then dG
to delete all lines. Finally, write and quit the file with wq
and your commit will be aborted.
Windows type
command works similarly to UNIX cat
.
Example 1: Merge with file names (This will merge file1.csv & file2.csv to create concat.csv)
type file1.csv file2.csv > concat.csv
Example 2: Merge files with pattern (This will merge all files with csv extension and create concat.csv)
When using asterisk(*) to concatenate all files. Please DON'T use same extension for target file(Eg. .csv). There should be some difference in pattern else target file will also be considered in concatenation
type *.csv > concat_csv.txt
Here's a real world example with the use of non-minified versus minified assets in your layout.
Web.Config
<appSettings>
<add key="Environment" value="Dev" />
</appSettings>
Razor Template - use that var above like this:
@if (System.Configuration.ConfigurationManager.AppSettings["Environment"] == "Dev")
{
<link type="text/css" rel="stylesheet" href="@Url.Content("~/Content/styles/theme.css" )">
}else{
<link type="text/css" rel="stylesheet" href="@Url.Content("~/Content/styles/blue_theme.min.css" )">
}
You should add namespace if you are not using it:
System.Windows.Forms.MessageBox.Show("Some text", "Some title",
System.Windows.Forms.MessageBoxButtons.OK,
System.Windows.Forms.MessageBoxIcon.Error);
Alternatively, you can add at the begining of your file:
using System.Windows.Forms
and then use (as stated in previous answers):
MessageBox.Show("Some text", "Some title",
MessageBoxButtons.OK, MessageBoxIcon.Error);

As far as I know, you can't ask apt
for what their current sources are. However, you can do what you want using shell tools.
Getting a list of repositories:
grep -h ^deb /etc/apt/sources.list /etc/apt/sources.list.d/* >> current.repos.list
Applying the list:
apt-add-repository << current.repos.list
Regarding getting the repository from a package (installed or available), this will do the trick:
apt-cache policy package_name | grep -m1 http | awk '{ print $2 " " $3 }'
However, that will show you the repository of the latest version available of that package, and you may have more repositories for the same package with older versions. Remove all the grep/awk stuff if you want to see the full list.
public static String currencyFormat(BigDecimal n) {
return NumberFormat.getCurrencyInstance().format(n);
}
It will use your JVM’s current default Locale
to choose your currency symbol. Or you can specify a Locale
.
NumberFormat.getInstance(Locale.US)
For more info, see NumberFormat
class.
If the script does its job (relatively) well, then it's running okay. Your problem is probably a single line in the file referencing a program that's either not on the path, not installed, misspelled, or something similar.
One way is to place a set -x
at the top of your script or run it with bash -x
instead of just bash
- this will output the lines before executing them and you usually just need to look at the command output immediately before the error to see what's causing the problem
If, as you say, it's the blank lines causing the problems, you might want to check what's actaully in them. Run:
od -xcb testscript.sh
and make sure there's no "invisible" funny characters like the CTRL-M
(carriage return) you may get by using a Windows-type editor.
You can also use Boost.Assignment:
const list<int> primes = list_of(2)(3)(5)(7)(11);
vector<int> v;
v += 1,2,3,4,5,6,7,8,9;
From wikipedia:
In computer science, an array data structure or simply array is a data structure consisting of a collection of elements (values or variables), each identified by one or more integer indices, stored so that the address of each element can be computed from its index tuple by a simple mathematical formula.
So when you say byte array, you're referring to an array of some defined length (e.g. number of elements) that contains a collection of byte (8 bits) sized elements.
In C# a byte array could look like:
byte[] bytes = { 3, 10, 8, 25 };
The sample above defines an array of 4 elements, where each element can be up to a Byte in length.
Definitely resize the image, and check it's format if you can. There have been cases of malicious files being uploaded and served by unwitting hosts- for instance, the GIFAR vulnerability allowed you to hide a malicious java applet in a GIF file, which would then be able to read cookies in the current context and send them to another site for a cross-site scripting attack. Resizing the images usually prevents this, as it munges the embedded code. While this attack has been fixed by JVM patches, naively serving up binary files without scrubbing them opens you up to a whole range of vulnerabilities.
Remember, most virus scanners can only run against the filesystem- if you store your binaries in the DB, you won't be able to run a scanner against them very easily.
(similar as Gustavo said, but additionally: )
For any previously search, you can do simply:
:%s///gn
A pattern is not needed, because it is already in the search-register (@/
).
"%" - do s/
in the whole file
"g" - search global (with multiple hits in one line)
"n" - prevents any replacement of s/
-- nothing is deleted! nothing must be undone!
(see: :help s_flag
for more informations)
(This way, it works perfectly with "Search for visually selected text", as described in vim-wikia tip171)
Please Try this code margin-left:60px

This happens because of the double-precision binary: IEEE 754 double-precision binary floating-point format: binary64
From the Wikipedia page for Double-precision floating-point format:
Double-precision binary floating-point is a commonly used format on PCs, due to its wider range over single-precision floating point, in spite of its performance and bandwidth cost. As with single-precision floating-point format, it lacks precision on integer numbers when compared with an integer format of the same size. It is commonly known simply as double. The IEEE 754 standard specifies a binary64 as having:
- Sign bit: 1 bit
- Exponent: 11 bits
- Significant precision: 53 bits (52 explicitly stored)
The real value assumed by a given 64-bit double-precision datum with a given biased exponent and a 52-bit fraction is
or
Thanks to @a_guest for pointing that out to me.
I believe there's no such option. Alternatively you can try this
set text=Hello
set text=%text% world
echo %text%
A slight variation on andrew.fox answer, as the string to decode might not be a correct base64 encoded string:
using System;
namespace Service.Support
{
public static class Base64
{
public static string ToBase64(this System.Text.Encoding encoding, string text)
{
if (text == null)
{
return null;
}
byte[] textAsBytes = encoding.GetBytes(text);
return Convert.ToBase64String(textAsBytes);
}
public static bool TryParseBase64(this System.Text.Encoding encoding, string encodedText, out string decodedText)
{
if (encodedText == null)
{
decodedText = null;
return false;
}
try
{
byte[] textAsBytes = Convert.FromBase64String(encodedText);
decodedText = encoding.GetString(textAsBytes);
return true;
}
catch (Exception)
{
decodedText = null;
return false;
}
}
}
}

There are couple of little visual studio extensions for this purpose:
In case of TFS 2012, looks like there is no need for 'Go offline' extensions. I read something about a new feature called local workspace for the similar purpose.
Alternatively I had good success with Git-TF. All the goodness of git and when you are ready, you can push it to TFS.

According to the React Documentation it's perfectly OK to call setState()
from within the componentDidMount()
function.
It will cause render()
to be called twice, which is less efficient than only calling it once, but other than that it's perfectly fine.
You can find the documentation here:
https://reactjs.org/docs/react-component.html#componentdidmount
Here is the excerpt from the documentation:
You may call setState() immediately in componentDidMount(). It will trigger an extra rendering, but it will happen before the browser updates the screen. This guarantees that even though the render() will be called twice in this case, the user won’t see the intermediate state. Use this pattern with caution because it often causes performance issues...
If you are using jQuery you can easily check the type of any element.
function(elementID){
var type = $(elementId).attr('type');
if(type == "text") //inputBox
console.log("input text" + $(elementId).val().size());
}
similarly you can check the other types and take appropriate action.
The first push should be a:
git push -u origin branchname
That would make sure:
origin
',simple
'Any future git push will, with that default policy, only push the current branch, and only if that branch has an upstream branch with the same name.
that avoid pushing all matching branches (previous default policy), where tons of test branches were pushed even though they aren't ready to be visible on the upstream repo.
You can do typeOf(T)
, but I would double check your method and make sure your not violating single responsability here. This would be a code smell, and that's not to say it shouldn't be done but that you should be cautious.
The point of generics is being able to build type-agnostic algorthims were you don't care what the type is or as long as it fits within a certain set of criteria. Your implementation isn't very generic.
I encountered this problem after these operations:
I finally resolved the problem by forcing the lock again : TortoiseSVN --> Get Lock --> check "steal lock" then commit or release lock.

The simplest way to log out and redirect back to the login or index:

exit();
?>
What is missing in the question and all the answers is that you might need the passphrase to read public data from the PKCS#12 (.pfx) keystore. If you need a passphrase or not depends on how the PKCS#12 file was created. You can check the ASN1 structure of the file (by running it through a ASN1 parser, openssl or certutil can do this too), if the PKCS#7 data (e.g. OID prefix 1.2.840.113549.1.7) is listed as 'encrypted' or with a cipher-spec or if the location of the data in the asn1 tree is below an encrypted node, you won't be able to read it without knowledge of the passphrase. It means your 'openssl pkcs12' command will fail with errors (output depends on the version). For those wondering why you might be interested in the certificate of a PKCS#12 without knowledge of the passphrase. Imagine you have many keystores and many phassphrases and you are really bad at keeping them organized and you don't want to test all combinations, the certificate inside the file could help you find out which password it might be. Or you are developing software to migrate/renew a keystore and you need to decide in advance which procedure to initiate based on the contained certicate without user interaction. So the latter examples work without passphrase depending on the PKCS#12 structure.
Just wanted to add that, because I didn't find an answer myself and spend a lot of time to figure it out.

PYTHONPATH
is an environment variable those content is added to the sys.path
where Python looks for modules. You can set it to whatever you like.
However, do not mess with PYTHONPATH
. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…
I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.
A simple way of using one instance of logging library in multiple modules for me was following solution:
import logging
logger = logging
logger.basicConfig(format='%(asctime)s - %(message)s', level=logging.INFO)
from base_logger import logger
if __name__ == '__main__':
logger.info("This is an info message")
fun triggerRestart(context: Activity) {
val intent = Intent(context, MainActivity::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
context.startActivity(intent)
if (context is Activity) {
(context as Activity).finish()
}
Runtime.getRuntime().exit(0)
}
After having oh so many problems with this thing (it's hard to debug the error since if you open the developer console the error no longer happens!) I decided to make an overkill code to never have to bother with this ever again:
if (typeof window.console === "undefined")
window.console = {};
if (typeof window.console.debug === "undefined")
window.console.debug= function() {};
if (typeof window.console.log === "undefined")
window.console.log= function() {};
if (typeof window.console.error === "undefined")
window.console.error= function() {alert("error");};
if (typeof window.console.time === "undefined")
window.console.time= function() {};
if (typeof window.console.trace === "undefined")
window.console.trace= function() {};
if (typeof window.console.info === "undefined")
window.console.info= function() {};
if (typeof window.console.timeEnd === "undefined")
window.console.timeEnd= function() {};
if (typeof window.console.group === "undefined")
window.console.group= function() {};
if (typeof window.console.groupEnd === "undefined")
window.console.groupEnd= function() {};
if (typeof window.console.groupCollapsed === "undefined")
window.console.groupCollapsed= function() {};
if (typeof window.console.dir === "undefined")
window.console.dir= function() {};
if (typeof window.console.warn === "undefined")
window.console.warn= function() {};
Personaly I only ever use console.log and console.error, but this code handles all the other functions as shown in the Mozzila Developer Network: https://developer.mozilla.org/en-US/docs/Web/API/console. Just put that code on the top of your page and you are done forever with this.
To use the default system proxies (e.g. from the http_support environment variable), the following works for the current request (without installing it into urllib2 globally):

in_ = opener.open(url)
in_.read()
It looks like there is actually a cross-platform way to do this that works on both iOS and Android (not sure about Windows). It uses only binding and does not require custom renderers (which seems rare). This is a mash-up of lots of googling, so thanks to anyone who I may have borrowed from...
I am assuming ViewCells, but this should work for Text or Image cells as well. I am only including the relevant code here beyond the typical text, image, etc.
On your page do something like this:
MyModel model1 = new MyModel();
MyModel model2 = new MyModel();
ListView list = new ListView
{
ItemsSource = new List<MyModel> { model1, model2 };
ItemTemplate = new DataTemplate( typeof(MyCell) )
};
Your custom Model might look something like this:
public class MyModel : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private Color _backgroundColor;
public Color BackgroundColor
{
get { return _backgroundColor; }
set
{
_backgroundColor = value;
if ( PropertyChanged != null )
{
PropertyChanged( this, new PropertyChangedEventArgs( "BackgroundColor" ) );
}
}
}
public void SetColors( bool isSelected )
{
if ( isSelected )
{
BackgroundColor = Color.FromRgb( 0.20, 0.20, 1.0 );
}
else
{
BackgroundColor = Color.FromRgb( 0.95, 0.95, 0.95 );
}
}
}
Then for your ItemTemplate you need a custom cell class something like this:
public class MyCell : ViewCell
{
public MyCell() : base()
{
RelativeLayout layout = new RelativeLayout();
layout.SetBinding( Layout.BackgroundColorProperty, new Binding( "BackgroundColor" ) );
View = layout;
}
}
Then in your ItemSelected event handler, do the following. Note that 'selected' is an instance of MyModel used to track the currently selected item. I am only showing background color here, but I also use this technique to reverse highlight the text and detail text colors.
private void ItemSelected( object sender, ItemTappedEventArgs args )
{
// Deselect previous
if ( selected != null )
{
selected.SetColors( false );
}
// Select new
selected = (list.SelectedItem as MyModel);
selected.SetColors( true );
}
The best solution, where en
is the English locale:
fraction.toLocaleString("en", {style: "percent"})
You're setting the global git options, but the local checkout possibly has overrides set. Try setting them again with git config --local <setting> <value>
. You can look at the .git/config
file in your local checkout to see what local settings the checkout has defined.
thanks kkudi! I was able to adapt your answer to work for an activity... here's what worked in my app..
public boolean isServiceRunning() {
ActivityManager activityManager = (ActivityManager)Monitor.this.getSystemService (Context.ACTIVITY_SERVICE);
List<RunningTaskInfo> services = activityManager.getRunningTasks(Integer.MAX_VALUE);
isServiceFound = false;
for (int i = 0; i < services.size(); i++) {
if (services.get(i).topActivity.toString().equalsIgnoreCase("ComponentInfo{com.lyo.AutoMessage/com.lyo.AutoMessage.TextLogList}")) {
isServiceFound = true;
}
}
return isServiceFound;
}
this example will give you a true or false if the topActivity matches what the user is doing. So if the activity your checking for is not being displayed (i.e. is onPause) then you won't get a match. Also, to do this you need to add the permission to your manifest..
<uses-permission android:name="android.permission.GET_TASKS"/>
I hope this was helpful!

I'm not really too clear what you are asking, but using the -f
command line option just specifies a file - it doesn't tell make to change directories. If you want to do the work in another directory, you need to cd
to the directory:
clean:
cd gtest-1.4.0 && $(MAKE) clean
Note that each line in Makefile
runs in a separate shell, so there is no need to change the directory back.

The js portion gets the element in the HTML to create the alert box, then deletes it after the user clicks ok.
You can call the alert using jAlert("Custom Text", "Ok!");
I was struggling with this, my app was installing but not complete (almost 60% I can say) in iOS8, but in iOS7.1 it was working as expected. The error message popped was:
"Cannot install at this time".
Finally Zillan's link helped me to get apple documentation. So, check:
ax.init.itunes.apple.com
is not getting blocked by your firewall/proxy (Just type this address in safari, a blank page must load). As soon as I changed the proxy it installed completely. Hope it will help someone.
Piping to xargs is a dirty way of doing that which can be done inside of find.
find . -type d -exec chmod 0755 {} \;
find . -type f -exec chmod 0644 {} \;
You can be even more controlling with other options, such as:
find . -type d -user harry -exec chown daisy {} \;
You can do some very cool things with find and you can do some very dangerous things too. Have a look at "man find", it's long but is worth a quick read. And, as always remember:
char **options[2][100];
declares a size-2 array of size-100 arrays of pointers to pointers to char
. You'll want to remove one *
. You'll also want to put your string literals in double quotes.
Static import is used to import static fields / method of a class instead of:
package test;
import org.example.Foo;
class A {
B b = Foo.B_INSTANCE;
}
You can write :
package test;
import static org.example.Foo.B_INSTANCE;
class A {
B b = B_INSTANCE;
}
It is useful if you are often used a constant from another class in your code and if the static import is not ambiguous.
Btw, in your example "import static org.example.Myclass;" won't work : import is for class, import static is for static members of a class.
I've updated Bryan's code for my Sierra iMac:
# this version was tested OK vith macOs Sierra 10.12.5 (16F73) on oct 0th, 2017
# original ipa file must be store in current working directory
IPA="ipa-filename.ipa"
PROVISION="path-to.mobileprovision"
CERTIFICATE="hexadecimal-certificate-identifier" # must be in keychain
# identifier maybe retrieved by running: security find-identity -v -p codesigning
# unzip the ipa
unzip -q "$IPA"
# remove the signature
rm -rf Payload/*.app/_CodeSignature
# replace the provision
cp "$PROVISION" Payload/*.app/embedded.mobileprovision
# generate entitlements for current app
cd Payload/
codesign -d --entitlements - *.app > entitlements.plist
cd ..
mv Payload/entitlements.plist entitlements.plist
# sign with the new certificate and entitlements
/usr/bin/codesign -f -s "$CERTIFICATE" '--entitlements' 'entitlements.plist' Payload/*.app
# zip it back up
zip -qr resigned.ipa Payload
I think for pretty-printing something, it's very helpful to know its structure.
To get the structure you have to parse it. Because of this, I don't think it gets much easier than first parsing the JSON string you have and then using the pretty-printing method toString mentioned in the comments above.
Of course you can do similar with any JSON library you like.
you should be using the .Value of the datetime parameter. All Nullable structs have a value property which returns the concrete type of the object. but you must check to see if it is null beforehand otherwise you will get a runtime error.
i.e:
datetime.Value
but check to see if it has a value first!
if (datetime.HasValue)
{
// work with datetime.Value
}
This is helped for me.
For select:
$('select_tags').on('change', function() {
alert( $(this).find(":selected").val() );
});
For radio/checkbox:
$('radio_tags').on('change', function() {
alert( $(this).find(":checked").val() );
});
For version 4.0, 4.5 on Windows

Deleting the .git
folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:
Checkout
git checkout --orphan latest_branch
Add all the files
git add -A
Commit the changes
git commit -am "commit message"
Delete the branch
git branch -D master
Rename the current branch to master
git branch -m master
Finally, force update your repository
git push -f origin master
PS: this will not keep your old commit history around
You can also check if your version is using MKL with:
import numpy
numpy.show_config()
To combine bitmasks you want to use bitwise-or. In the trivial case where every value you combine has exactly 1 bit on (like your example), it's equivalent to adding them. If you have overlapping bits however, or'ing them handles the case gracefully.
To decode the bitmasks you and your value with a mask, like so:
if(val & (1<<1)) SusanIsOn();
if(val & (1<<2)) BobIsOn();
if(val & (1<<3)) KarenIsOn();
You can use smartbind
from the gtools
package.
Example:
library(gtools)
df1 <- data.frame(a = c(1:5), b = c(6:10))
df2 <- data.frame(a = c(11:15), b = c(16:20), c = LETTERS[1:5])
smartbind(df1, df2)
# result
a b c
1.1 1 6 <NA>
1.2 2 7 <NA>
1.3 3 8 <NA>
1.4 4 9 <NA>
1.5 5 10 <NA>
2.1 11 16 A
2.2 12 17 B
2.3 13 18 C
2.4 14 19 D
2.5 15 20 E
I found my solution from this similar thread by enabling USB tethering on my LG G6 (requires data saver to be turned off)
Go to: Settings -> Tethering & networks -> switch on USB tethering
How about this?
JSONObject jsonObject = new JSONObject (YOUR_JSON_STRING);
JSONObject ipinfo = jsonObject.getJSONObject ("ipinfo");
String ip_address = ipinfo.getString ("ip_address");
JSONObject location = ipinfo.getJSONObject ("Location");
String latitude = location.getString ("latitude");
System.out.println (latitude);
This sample code using "org.json.JSONObject"
What worked for me was adding myWindow.document.close()
after myWindow.document.write()
. Here's my solution with a timeout to wait for the new window to finish loading (if you have a lot to load):
var win = window.open('', 'PrintWindow');
win.document.write('Stuff to print...');
setTimeout(function () {
win.document.close();
win.focus();
win.print();
win.close();
}, 1000);
What others said is correct but for those who still face the same problem:
In my case it happened because I copied another project n renamed it to something else BUT previous output files in bin
folder were still there... And unfortunately, hitting Build -> Clean Solution
after renaming the project and its Namespaces
doesn't remove them... so deleting them manually solved my problem!
For Postgresql you can use PERFORM. PERFORM is only valid within PL/PgSQL procedure language.
DO $$ BEGIN
PERFORM "saveUser"(3, 'asd','asd','asd','asd','asd');
END $$;
The suggestion from the postgres team:
HINT: If you want to discard the results of a SELECT, use PERFORM instead.
Here is a quick summary of the segues and an example for each type.
Show - Pushes the destination view controller onto the navigation stack, sliding overtop from right to left, providing a back button to return to the source - or if not embedded in a navigation controller it will be presented modally
Example: Navigating inboxes/folders in Mail
Show Detail - For use in a split view controller, replaces the detail/secondary view controller when in an expanded 2 column interface, otherwise if collapsed to 1 column it will push in a navigation controller
Example: In Messages, tapping a conversation will show the conversation details - replacing the view controller on the right when in a two column layout, or push the conversation when in a single column layout
Present Modally - Presents a view controller in various animated fashions as defined by the Presentation option, covering the previous view controller - most commonly used to present a view controller that animates up from the bottom and covers the entire screen on iPhone, or on iPad it's common to present it as a centered box that darkens the presenting view controller
Example: Selecting Touch ID & Passcode in Settings
Popover Presentation - When run on iPad, the destination appears in a popover, and tapping anywhere outside of this popover will dismiss it, or on iPhone popovers are supported as well but by default it will present the destination modally over the full screen
Example: Tapping the + button in Calendar
Custom - You may implement your own custom segue and have control over its behavior
The deprecated segues are essentially the non-adaptive equivalents of those described above. These segue types were deprecated in iOS 8: Push, Modal, Popover, Replace.
For more info, you may read over the Using Segues documentation which also explains the types of segues and how to use them in a Storyboard. Also check out Session 216 Building Adaptive Apps with UIKit from WWDC 2014. They talked about how you can build adaptive apps using these new Adaptive Segues, and they built a demo project that utilizes these segues.
GitHub Pages is GitHub’s official solution to this problem.
raw.githubusercontent
makes all files use the text/plain
MIME type, even if the file is a CSS or JavaScript file. So going to https://raw.githubusercontent.com/‹user›/‹repo›/‹branch›/‹filepath›
will not be the correct MIME type but instead a plaintext file, and linking it via <link href="..."/>
or <script src="..."></script>
won’t work—the CSS won’t apply / the JS won’t run.
GitHub Pages hosts your repo at a special URL, so all you have to do is check-in your files and push. Note that in most cases, GitHub Pages requires you to commit to a special branch, gh-pages
.
On your new site, which is usually https://‹user›.github.io/‹repo›
, every file committed to the gh-pages
branch (the most recent commit) is present at this url. So then you can link to your js file via <script src="https://‹user›.github.io/‹repo›/file.js"></script>
, and this will be the correct MIME type.
Personally, my recommendation is to run this branch parallel to master
. On the gh-pages
branch, you can edit your .gitignore
file to check in all the dist/build files you need for your site (e.g. if you have any minified/compiled files), while keeping them ignored on your master
branch. This is useful because you typically don’t want to track changes in build files in your regular repo. Every time you want to update your hosted files, simply merge master
into gh-pages
, rebuild, commit, and then push.
(protip: you can merge and rebuild in the same commit with these steps:)
$ git checkout gh-pages
$ git merge --no-ff --no-commit master # prepare the merge but don’t commit it (as if there were a merge conflict)
$ npm run build # (or whatever your build process is)
$ git add . # stage the newly built files
$ git merge --continue # commit the merge
$ git push origin gh-pages

I succeeded in defining nested routes by wrapping with Switch
and define nested route before than root route.
<BrowserRouter>
<Switch>
<Route path="/staffs/:id/edit" component={StaffEdit} />
<Route path="/staffs/:id" component={StaffShow} />
<Route path="/staffs" component={StaffIndex} />
</Switch>
</BrowserRouter>
Reference: https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/api/Switch.md
If .java
file contains top level (not nested) public
class, it have same name as that public class. So if you have class like public class A{...}
it needs to be placed in A.java
file. Because of that we can't have two public classes in one .java
file.
If having two public classes would be allowed then, and lets say aside from public A
class file would also contain public class B{}
it would require from A.java
file to be also named as B.java
but files can't have two (or more) names (at least in all systems on which Java can be run).
So assuming your code is placed in StaticDemoShow.java
file you have two options:
If you want to have other class in same file make them non-public (lack of visibility modifier will represent default/package-private visibility)
class StaticDemo { // It can no longer public
static int a = 3;
static int b = 4;
static {
System.out.println("Voila! Static block put into action");
}
static void show() {
System.out.println("a= " + a);
System.out.println("b= " + b);
}
}
public class StaticDemoShow { // Only one top level public class in same .java file
public static void main() {
StaticDemo.show();
}
}
Move all public classes to their own .java
files. So in your case you would need to split it into two files:
StaticDemo.java
public class StaticDemo { // Note: same name as name of file
static int a = 3;
static int b = 4;
static {
System.out.println("Voila! Static block put into action");
}
static void show() {
System.out.println("a= " + a);
System.out.println("b= " + b);
}
}
StaticDemoShow.java
public class StaticDemoShow {
public static void main() {
StaticDemo.show();
}
}
I just did this successfully by using the following CSS code.
@media(max-width:1000px) {
.navbar-collapse.collapse {
display: none !important;
}
.navbar-collapse {
overflow-x: visible !important;
}
.navbar-collapse.in {
overflow-y: auto !important;
}
.collapse.in {
display: block !important;
}
}
You could use inline styles and define the width in the <th>
tag. Make it so that the sum of the widths = 100%.
<tr>
<th style="width:10%">Size</th>
<th style="width:30%">Bust</th>
<th style="width:50%">Waist</th>
<th style="width:10%">Hips</th>
</tr>
Typically using inline styles is not ideal, however this does provide flexibility because you can get very specific and granular with exact widths.
There are three char types: (plain) char
, signed char
and unsigned char
. Any char is usually an 8-bit integer* and in that sense, a signed
and unsigned char
have a useful meaning (generally equivalent to uint8_t
and int8_t
). When used as a character in the sense of text, use a char
(also referred to as a plain char). This is typically a signed char
but can be implemented either way by the compiler.
* Technically, a char can be any size as long as sizeof(char)
is 1, but it is usually an 8-bit integer.
One of the aspects of .NET I like the most are generics. Even if you write procedural code in F#, you will still benefit from type inference. It makes writing generic code easy.
In C#, you write concrete code by default, and you have to put in some extra work to write generic code.
In F#, you write generic code by default. After spending over a year of programming in both F# and C#, I find that library code I write in F# is both more concise and more generic than the code I write in C#, and is therefore also more reusable. I miss many opportunities to write generic code in C#, probably because I'm blinded by the mandatory type annotations.
There are however situations where using C# is preferable, depending on one's taste and programming style.
I'm not sure I understand the question correctly, but if you want to prevent people from writing in the input field you can use the disabled
attribute.
<input disabled="disabled" id="price_from" value="price from ">
Check out printf...
#!/bin/bash
mystr="say \"hi\""
Without using printf
echo -e $mystr
Output: say "hi"
Using printf
echo -e $(printf '%q' $mystr)
Output: say \"hi\"
Simply:
/^([^0-9]*)$/
That pattern matches any number of characters that is not 0
through 9
.
I recommend checking out http://regexpal.com/. It will let you easily test out a regex.
Create your assets directory the same as lib level
like this
projectName
-android
-ios
-lib
-assets
-pubspec.yaml
then your pubspec.yaml like
flutter:
assets:
- assets/images/
now you can use Image.asset("/assets/images/")
Just did a quick test on ubuntu:
installed mysql-server, which created /etc/mysql/my.cnf
mysqld --verbose --help | grep -A 1 "Default options"
110112 13:35:26 [Note] Plugin 'FEDERATED' is disabled.
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf
created /etc/my.cnf and /usr/etc/my.cnf, each with a different port number
restarted mysql - it was using the port number set in /usr/etc/my.cnf
Also meanwhile found the --defaults-file option to the mysqld. If you specify a config file there, only that one will be used, regardless of what is returned by /usr/sbin/mysqld --verbose --help | grep -A 1 "Default options"
I know it's way too late to answer this question, but I'll just post the solution that worked for me, in case someone runs into trouble again in the future.
I tried using genymotion's own adb tools and the original Android SDK ones, and even purging and reinstalling adb from my system, but nothing worked. I kept getting the error:
adb server is out of date. killing...
cannot bind 'tcp:5037'
ADB server didn't ACK
*failed to start daemon*
error:
So I tried adb connect [ip]
as suggested here, but I didn't work either, the same error came up.
What finally worked for me was downloading ADT, and running adb directly from the downloaded folder, instead of the system-wide command. So adb devices
will give me the error above, but /yourdownloadpath/adb devices
works just fine for me.
Hope it helped.
A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
Whereas a GridLayout is a layout that places its children in a rectangular grid.
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.
I had the same problem (don't know why).
This fix requires access to an uncorrupted remote copy of the repository, and will keep your locally working copy intact.
But it has some drawbacks:
Execute these commands from the parent directory above your repo (replace 'foo' with the name of your project folder):
cp -R foo foo-backup
git clone [email protected]:foo foo-newclone
rm -rf foo/.git
mv foo-newclone/.git foo
rm -rf foo-newclone
On Windows you will need to use:
copy
instead of cp -R
rmdir /S
instead of rm -rf
move
instead of mv
Now foo has its original .git
subdirectory back, but all the local changes are still there. git status
, commit
, pull
, push
, etc. work again as they should.

There is a ToArray() function on Values:
Foo[] arr = new Foo[dict.Count];
dict.Values.CopyTo(arr, 0);
But I don't think its efficient (I haven't really tried, but I guess it copies all these values to the array). Do you really need an Array? If not, I would try to pass IEnumerable:
IEnumerable<Foo> foos = dict.Values;
res
is an HttpResponse object which extends from OutgoingMessage. res.send
calls res.end
which is implemented by OutgoingMessage to send HTTP response and close connection. We see code here
Another approach (more words, less code) that may help:
The locations of local maxima and minima are also the locations of the zero crossings of the first derivative. It is generally much easier to find zero crossings than it is to directly find local maxima and minima.
Unfortunately, the first derivative tends to "amplify" noise, so when significant noise is present in the original data, the first derivative is best used only after the original data has had some degree of smoothing applied.
Since smoothing is, in the simplest sense, a low pass filter, the smoothing is often best (well, most easily) done by using a convolution kernel, and "shaping" that kernel can provide a surprising amount of feature-preserving/enhancing capability. The process of finding an optimal kernel can be automated using a variety of means, but the best may be simple brute force (plenty fast for finding small kernels). A good kernel will (as intended) massively distort the original data, but it will NOT affect the location of the peaks/valleys of interest.
Fortunately, quite often a suitable kernel can be created via a simple SWAG ("educated guess"). The width of the smoothing kernel should be a little wider than the widest expected "interesting" peak in the original data, and its shape will resemble that peak (a single-scaled wavelet). For mean-preserving kernels (what any good smoothing filter should be) the sum of the kernel elements should be precisely equal to 1.00, and the kernel should be symmetric about its center (meaning it will have an odd number of elements.
Given an optimal smoothing kernel (or a small number of kernels optimized for different data content), the degree of smoothing becomes a scaling factor for (the "gain" of) the convolution kernel.
Determining the "correct" (optimal) degree of smoothing (convolution kernel gain) can even be automated: Compare the standard deviation of the first derivative data with the standard deviation of the smoothed data. How the ratio of the two standard deviations changes with changes in the degree of smoothing cam be used to predict effective smoothing values. A few manual data runs (that are truly representative) should be all that's needed.
All the prior solutions posted above compute the first derivative, but they don't treat it as a statistical measure, nor do the above solutions attempt to performing feature preserving/enhancing smoothing (to help subtle peaks "leap above" the noise).
Finally, the bad news: Finding "real" peaks becomes a royal pain when the noise also has features that look like real peaks (overlapping bandwidth). The next more-complex solution is generally to use a longer convolution kernel (a "wider kernel aperture") that takes into account the relationship between adjacent "real" peaks (such as minimum or maximum rates for peak occurrence), or to use multiple convolution passes using kernels having different widths (but only if it is faster: it is a fundamental mathematical truth that linear convolutions performed in sequence can always be convolved together into a single convolution). But it is often far easier to first find a sequence of useful kernels (of varying widths) and convolve them together than it is to directly find the final kernel in a single step.
Hopefully this provides enough info to let Google (and perhaps a good stats text) fill in the gaps. I really wish I had the time to provide a worked example, or a link to one. If anyone comes across one online, please post it here!
I faced the same problem and here's the solution I implemented with ES6
code
let id = 0; // This is a kind of global variable accessible for every instance
class Animal {
constructor(name){
this.name = name;
this.id = id++;
}
foo(){}
// Executes some cool stuff
}
cat = new Animal("Catty");
console.log(cat.id) // 1
I think you should add style="background:white;" to make looks like it is writable
<input type="text" size="23" name="dateMonthly" id="dateMonthly" readonly="readonly" style="background:white;"/>
In javascript there are no block-level scopes
only function-level scopes
:
Read this article about javaScript Scoping and Hoisting.
var deferred = $q.defer();
deferred.count = i;
console.log(deferred.count); // 0,1,2,3,4,5 --< all deferred objects
// some code
.success(function(data){
console.log(deferred.count); // 5,5,5,5,5,5 --< only the last deferred object
deferred.resolve(data);
})
var deferred= $q.defer();
inside a for loop it's hoisted to the top of the function, it means that javascript declares this variable on the function scope outside of the for loop
.closure scope
even after functions are executed.angular.forEach
:Here is a demo plunker: http://plnkr.co/edit/NGMp4ycmaCqVOmgohN53?p=preview

var promise = $http({
url : 'upload/question',

});
promises.push(promise);
});
return $q.all(promises);
}

If you are using jQuery you can also do this:
$('#leaveCode').val('14');
This will select the <option>
with the value of 14.
With plain Javascript, this can also be achieved with two Document
methods:
With document.querySelector
, you can select an element based on a CSS selector:
document.querySelector('#leaveCode').value = '14'
Using the more established approach with document.getElementById()
, that will, as the name of the function implies, let you select an element based on its id
:
document.getElementById('leaveCode').value = '14'
You can run the below code snipped to see these methods and the jQuery function in action:
const jQueryFunction = () => {_x000D_
_x000D_
$('#leaveCode').val('14'); _x000D_
_x000D_
}_x000D_
_x000D_

document.querySelector('#leaveCode').value = '14' _x000D_

}_x000D_

const getElementByIdFunction = () => {_x000D_

Submit your tasks into the Runner and then wait calling the method waitTillDone() like this:
Runner runner = Runner.runner(2);
for (DataTable singleTable : uniquePhrases) {
runner.run(new ComputeDTask(singleTable));
}
// blocks until all tasks are finished (or failed)
runner.waitTillDone();
runner.shutdown();

NOTE: The HTML/CSS code below should be viewed in IE only. The code will not be rendered correctly in Chrome!
We need to remember that:
A table has a border: its outer boundary (which can also have a border-radius.)
The cells themselves ALSO have borders (which too, can also have a border-radius.)
The table and cell borders can interfere with each other:
The cell border can pierce through the table border (ie: table boundary).
To see this effect, amend the CSS style rules in the code below as follows:
i. table {border-collapse: separate;}
ii. Delete the style rules which round the corner cells of the table.
iii. Then play with border-spacing so you can see the interference.
However, the table border and cell borders can be COLLAPSED (using: border-collapse: collapse;).
When they are collapsed, the cell and table borders interfere in a different way:
i. If the table border is rounded but cell borders remain square, then the cell's shape takes precedence and the table loses its curved corners.
ii. Conversely, if the corner cell's are curved but the table boundary is square, then you will see an ugly square corner bordering the curvature of the corner cells.
Given that cell's attribute takes precedence, the way to round the table's four corner's then, is by:
i. Collapsing borders on the table (using: border-collapse: collapse;).
ii. Setting your desired curvature on the corner cells of the table.
iii. It does not matter if the table's corner's are rounded (ie: Its border-radius can be zero).

You could make a little Tkinter app:
import Tkinter as tk
def onKeyPress(event):
text.insert('end', 'You pressed %s\n' % (event.char, ))
root = tk.Tk()
root.geometry('300x200')
text = tk.Text(root, background='black', foreground='white', font=('Comic Sans MS', 12))
text.pack()
root.bind('<KeyPress>', onKeyPress)
root.mainloop()
Just for the record, if you are using eslint-plugin-vue, the correct place to add 'parser': 'babel-eslint'
is inside parserOptions
param.
'parserOptions': {
'parser': 'babel-eslint',
'ecmaVersion': 2018,
'sourceType': 'module'
}
This is a favorite interview question. With this questions, the interviewer tries to find out how well you understand the behavior of objects with respect to constructors, methods, class variables (static variables) and instance variables.
import java.util.ArrayList;
import java.util.List;
class Test {
private final List foo;
public Test() {
foo = new ArrayList();
foo.add("foo"); // Modification-1
}
public void setFoo(List foo) {
//this.foo = foo; Results in compile time error.
}
}
In the above case, we have defined a constructor for 'Test' and gave it a 'setFoo' method.
About constructor: Constructor can be invoked only one time per object creation by using the new
keyword. You cannot invoke constructor multiple times, because constructor are not designed to do so.
About method: A method can be invoked as many times as you want (Even never) and the compiler knows it.
Scenario 1
private final List foo; // 1
foo
is an instance variable. When we create Test
class object then the instance variable foo
, will be copied inside the object of Test
class. If we assign foo
inside the constructor, then the compiler knows that the constructor will be invoked only once, so there is no problem assigning it inside the constructor.
If we assign foo
inside a method, the compiler knows that a method can be called multiple times, which means the value will have to be changed multiple times, which is not allowed for a final
variable. So the compiler decides constructor is good choice! You can assign a value to a final variable only one time.
Scenario 2
private static final List foo = new ArrayList();
foo
is now a static variable. When we create an instance of Test
class, foo
will not be copied to the object because foo
is static. Now foo
is not an independent property of each object. This is a property of Test
class. But foo
can be seen by multiple objects and if every object which is created by using the new
keyword which will ultimately invoke the Test
constructor which changes the value at the time of multiple object creation (Remember static foo
is not copied in every object, but is shared between multiple objects.)
Scenario 3
t.foo.add("bar"); // Modification-2
Above Modification-2
is from your question. In the above case, you are not changing the first referenced object, but you are adding content inside foo
which is allowed. Compiler complains if you try to assign a new ArrayList()
to the foo
reference variable.
Rule If you have initialized a final
variable, then you cannot change it to refer to a different object. (In this case ArrayList
)
final classes cannot be subclassed
final methods cannot be overridden. (This method is in superclass)
final methods can override. (Read this in grammatical way. This method is in a subclass)
Here is other example:
import numpy as np
import pandas as pd
""" This just creates a list of touples, and each element of the touple is an array"""
a = [ (np.random.randint(1,10,10), np.array([0,1,2,3,4,5,6,7,8,9])) for i in
range(0,10) ]
""" Panda DataFrame will allocate each of the arrays , contained as a touple
element , as column"""
df = pd.DataFrame(data =a,columns=['random_num','sequential_num'])
The secret in general is to allocate the data in the form a = [ (array_11, array_12,...,array_1n),...,(array_m1,array_m2,...,array_mn) ] and panda DataFrame will order the data in n columns of arrays. Of course , arrays of arrays could be used instead of touples, in that case the form would be : a = [ [array_11, array_12,...,array_1n],...,[array_m1,array_m2,...,array_mn] ]
This is the output if you print(df) from the code above:
random_num sequential_num
0 [7, 9, 2, 2, 5, 3, 5, 3, 1, 4] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
1 [8, 7, 9, 8, 1, 2, 2, 6, 6, 3] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
2 [3, 4, 1, 2, 2, 1, 4, 2, 6, 1] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
3 [3, 1, 1, 1, 6, 2, 8, 6, 7, 9] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
4 [4, 2, 8, 5, 4, 1, 2, 2, 3, 3] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
5 [3, 2, 7, 4, 1, 5, 1, 4, 6, 3] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
6 [5, 7, 3, 9, 7, 8, 4, 1, 3, 1] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
7 [7, 4, 7, 6, 2, 6, 3, 2, 5, 6] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
8 [3, 1, 6, 3, 2, 1, 5, 2, 2, 9] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
9 [7, 2, 3, 9, 5, 5, 8, 6, 9, 8] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Other variation of the example above:
b = [ (i,"text",[14, 5,], np.array([0,1,2,3,4,5,6,7,8,9])) for i in
range(0,10) ]
df = pd.DataFrame(data=b,columns=['Number','Text','2Elemnt_array','10Element_array'])
Output of df:
Number Text 2Elemnt_array 10Element_array
0 0 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
1 1 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
2 2 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
3 3 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
4 4 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
5 5 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
6 6 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
7 7 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
8 8 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
9 9 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
If you want to add other columns of arrays, then:
df['3Element_array']=[([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3])]
The final output of df will be:
Number Text 2Elemnt_array 10Element_array 3Element_array
0 0 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] [1, 2, 3]

2 2 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] [1, 2, 3]
3 3 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] [1, 2, 3]
4 4 text [14, 5] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] [1, 2, 3]

A lot of the times the implementation will exist in the same namespace as the interface. So, I came up with this:
public class InterfaceConverter : JsonConverter
{
public override bool CanWrite => false;
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
var token = JToken.ReadFrom(reader);
var typeVariable = this.GetTypeVariable(token);
if (TypeExtensions.TryParse(typeVariable, out var implimentation))
{ }
else if (!typeof(IEnumerable).IsAssignableFrom(objectType))
{
implimentation = this.GetImplimentedType(objectType);
}
else
{
var genericArgumentTypes = objectType.GetGenericArguments();
var innerType = genericArgumentTypes.FirstOrDefault();
if (innerType == null)
{
implimentation = typeof(IEnumerable);
}
else
{
Type genericType = null;
if (token.HasAny())
{
var firstItem = token[0];
var genericTypeVariable = this.GetTypeVariable(firstItem);
TypeExtensions.TryParse(genericTypeVariable, out genericType);
}
genericType = genericType ?? this.GetImplimentedType(innerType);
implimentation = typeof(IEnumerable<>);
implimentation = implimentation.MakeGenericType(genericType);
}
}
return JsonConvert.DeserializeObject(token.ToString(), implimentation);
}
public override bool CanConvert(Type objectType)
{
return !typeof(IEnumerable).IsAssignableFrom(objectType) && objectType.IsInterface || typeof(IEnumerable).IsAssignableFrom(objectType) && objectType.GetGenericArguments().Any(t => t.IsInterface);
}
protected Type GetImplimentedType(Type interfaceType)
{
if (!interfaceType.IsInterface)
{
return interfaceType;
}
var implimentationQualifiedName = interfaceType.AssemblyQualifiedName?.Replace(interfaceType.Name, interfaceType.Name.Substring(1));
return implimentationQualifiedName == null ? interfaceType : Type.GetType(implimentationQualifiedName) ?? interfaceType;
}
protected string GetTypeVariable(JToken token)
{
if (!token.HasAny())
{
return null;
}
return token.Type != JTokenType.Object ? null : token.Value<string>("$type");
}
}
Therefore, you can include this globally like so:
public static JsonSerializerSettings StandardSerializerSettings => new JsonSerializerSettings
{
Converters = new List<JsonConverter>
{
new InterfaceConverter()
}
};
Is the opaque overlay for aesthetic purposes?
If so, you can use:
#overlay {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 50;
background: #000;
pointer-events: none;
opacity: 0.8;
color: #fff;
}
'pointer-events: none' will change the overlay behavior so that it can be physically opaque. Of course, this will only work in good browsers.
Before writing this off as impossible I suggest you look at the source code of the lsof command.
There may be restrictions but lsof seems capable of determining the file descriptor and file name. This information exists in the /proc filesystem so it should be possible to get at from your program.
Other than the given answers, in the case that you have something like this:
<div id="test">
<input type="file" name="file0" onchange="changed()">
</div>
<script type="text/javascript">
var isAllowed = true;
function changed()
{
if (isAllowed)
{
var tmpHTML = $('#test').html();
tmpHTML += "<input type=\"file\" name=\"file1\" onchange=\"changed()\">";
$('#test').html(tmpHTML);
isAllowed = false;
}
}
</script>
meaning that you want to automatically add one more file upload if any files were uploaded, the mentioned code will not work, because after the file is uploaded, the first file-upload element will be recreated and therefore the uploaded file will be wiped from it. You should use .append() instead:
function changed()
{
if (isAllowed)
{
var tmpHTML = "<input type=\"file\" name=\"file1\" onchange=\"changed()\">";
$('#test').append(tmpHTML);
isAllowed = false;
}
}
if you use the eclipse, see the bellow image to allow the compiler to store the information about method parameters
function getKeys(obj){
var keys = [];
for (key in obj) {
if (obj.hasOwnProperty(key)) { keys[keys.length] = key; }
}
return keys;
}
Run this:
curl http://169.254.169.254/latest/meta-data/
You will be able to see different types of attributes which are provided by aws.
You are not allowed to use the concatenation operator with the case statement. One possible solution is to use a variable within the process:
process(b0,b1,b2,b3)
variable bcat : std_logic_vector(0 to 3);
begin
bcat := b0 & b1 & b2 & b3;
case bcat is
when "0000" => x <= 1;
when others => x <= 2;
end case;
end process;
I've added a "Connected Service" to our project by Visual Studio which generated a default method to create Client.
var client = new MyWebService.Client(MyWebService.Client.EndpointConfiguration.MyPort, _endpointUrl);
This constructor inherits ClientBase and behind the scene is creating Binding by using its own method Client.GetBindingForEndpoint(endpointConfiguration):
public Client(EndpointConfiguration endpointConfiguration, string remoteAddress) :
base(Client.GetBindingForEndpoint(endpointConfiguration),
new System.ServiceModel.EndpointAddress(remoteAddress))
This method has different settings for https service and http service. When you want get data from http, you should use TransportCredentialOnly:
System.ServiceModel.BasicHttpBinding result = new System.ServiceModel.BasicHttpBinding();
result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportCredentialOnly;
For https you should use Transport:
result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;

It's cool. However, it failed to backup my database correctly. Hence, I've modified it.
Please use like so: Backup_Mysql_Db::init("localhost","user","pass","db_name","/usr/var/output_dir" );

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.
use <br/>
tag
Example:
<string name="copyright"><b>@</b> 2014 <br/>
Corporation.<br/>
<i>All rights reserved.</i></string>
To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.
public $keyType = 'string'
Eloquent understands any of the types defined in the castAttribute()
function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.
This will ensure that your primary key is correctly cast into the equivalent PHP data type.
Overview: In this code snippet, I demonstrate how to group by ID where Table1 and Table2 have a one to many relationship. I group on Id, Field1, and Field2. The subquery is helpful, if a third Table lookup is required and it would have required a left join relationship. I show a left join grouping and a subquery linq. The results are equivalent.
class MyView
{
public integer Id {get,set};
public String Field1 {get;set;}
public String Field2 {get;set;}
public String SubQueryName {get;set;}
}
IList<MyView> list = await (from ci in _dbContext.Table1
join cii in _dbContext.Table2
on ci.Id equals cii.Id
where ci.Field1 == criterion
group new
{
ci.Id
} by new { ci.Id, cii.Field1, ci.Field2}
into pg
select new MyView
{
Id = pg.Key.Id,
Field1 = pg.Key.Field1,
Field2 = pg.Key.Field2,
SubQueryName=
(from chv in _dbContext.Table3 where chv.Id==pg.Key.Id select chv.Field1).FirstOrDefault()
}).ToListAsync<MyView>();
Compared to using a Left Join and Group new
IList<MyView> list = await (from ci in _dbContext.Table1
join cii in _dbContext.Table2
on ci.Id equals cii.Id
join chv in _dbContext.Table3
on cii.Id equals chv.Id into lf_chv
from chv in lf_chv.DefaultIfEmpty()
where ci.Field1 == criterion
group new
{
ci.Id
} by new { ci.Id, cii.Field1, ci.Field2, chv.FieldValue}
into pg
select new MyView
{
Id = pg.Key.Id,
Field1 = pg.Key.Field1,
Field2 = pg.Key.Field2,
SubQueryName=pg.Key.FieldValue
}).ToListAsync<MyView>();
Model
[Required(ErrorMessage = "You must provide a phone number")]
[Display(Name = "Home Phone")]
[DataType(DataType.PhoneNumber)]
[RegularExpression(@"^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$", ErrorMessage = "Not a valid phone number")]
public string PhoneNumber { get; set; }
View:
@Html.LabelFor(model => model.PhoneNumber)
@Html.EditorFor(model => model.PhoneNumber)

You are looking for child_process.exec
Here is the example:
const exec = require('child_process').exec;
const child = exec('cat *.js bad_file | wc -l',
(error, stdout, stderr) => {
console.log(`stdout: ${stdout}`);
console.log(`stderr: ${stderr}`);
if (error !== null) {
console.log(`exec error: ${error}`);
}
});
First make sure that equals is implemented correctly. From an IBM DeveloperWorks article:
- Symmetry: For two references, a and b, a.equals(b) if and only if b.equals(a)
- Reflexivity: For all non-null references, a.equals(a)
- Transitivity: If a.equals(b) and b.equals(c), then a.equals(c)
Then make sure that their relation with hashCode respects the contact (from the same article):
- Consistency with hashCode(): Two equal objects must have the same hashCode() value
Finally a good hash function should strive to approach the ideal hash function.

I do not feel there is anything wrong with using JQuery with angular and bootstrap, since it is included when adding bootstrap.
import {.......
declare var $: any;
@component.....
<div id="errorModal" class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" ..............
showErrorModal() {
$("#errorModal").modal('show');
}
function loadMarkers(){
{% for location in object_list %}
var point = new google.maps.LatLng({{location.latitude}},{{location.longitude}});
var marker = new google.maps.Marker({
position: point,
map: map,
url: {{location.id}},
});
google.maps.event.addDomListener(marker, 'click', function() {
window.location.href = this.url; });
{% endfor %}
To put it short 'value' is not an valid attribute of div. So it's absolutely correct to return undefined.
What you could do was something in the line of using one of the HTML5 attributes 'data-*'
<div id="demo" align="center" data-value="1">
And the script would be:
var val = document.getElementById('demo').getAttribute('data-value');
This should work in most modern browsers
Just remember to put your doctype as <!DOCTYPE html>

Log in as root, then run the following MySQL commands:
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;
request.remote_ip
is an interpretation of all the available IP address information and it will make a best-guess. If you access the variables directly you assume responsibility for testing them in the correct precedence order. Proxies introduce a number of headers that create environment variables with different names.
Just to add to the helpful and detailed answer:
If you have to check the exit code explicitly, it is better to use the arithmetic operator, (( ... ))
, this way:
run_some_command
(($? != 0)) && { printf '%s\n' "Command exited with non-zero"; exit 1; }
Or, use a case
statement:
run_some_command; ec=$? # grab the exit code into a variable so that it can
# be reused later, without the fear of being overwritten
case $ec in
0) ;;
1) printf '%s\n' "Command exited with non-zero"; exit 1;;
*) do_something_else;;

Related answer about error handling in Bash:
I do not know why the answer of @user1010160 got rating of 0. I would have given it +1 if I had enough reputations.
Since my app is designed for API less than 14 and I did not want to add code to my program I did not find a solution until I read his answer. What he said was that even though you have done what is needed in the Application styles it will not work unless you add a style to your activity and there you set textAllCaps to false.
It is not enough to have a style for the activity (my activity had a style), because the style might defaults to the AllCaps property. You have to set explicitly, in the activity too, that property to false.
I now have it both in the Application and in the Activity parts of the manifest file.
Probably you just want this:
dictList = dict.items()
Your approach has two problems. For one you use key
and value
in quotes, which are strings with the letters "key" and "value", not related to the variables of that names. Also you keep adding elements to the "temporary" list and never get rid of old elements that are already in it from previous iterations. Make sure you have a new and empty temp
list in each iteration and use the key
and value
variables:
for key, value in dict.iteritems():
temp = []
aKey = key
aValue = value
temp.append(aKey)
temp.append(aValue)
dictList.append(temp)
Also note that this could be written shorter without the temporary variables (and in Python 3 with items()
instead of iteritems()
):
for key, value in dict.items():
dictList.append([key, value])
You can use settype method too!
SetType($var,"Boolean") Echo $var //see 0 or 1
This will convert to a numeric value without the need to cast or specify length or digits:
STRING_COL+0.0
If your column is an INT
, can leave off the .0
to avoid decimals:
STRING_COL+0
If your whitespace is consistent you could use that as a delimiter, also instead of inserting \t
directly, you could set the output separator and it will be included automatically:
< file awk -v OFS='\t' -v FS='[/ ]' '{print $3, $5, $NF}'
I pretty much like the (relatively) new java.time library: it's close to awesome, imho.
You can calculate a duration between two instants this way:
import java.time.*
Instant before = Instant.now();
// do stuff
Instant after = Instant.now();
long delta = Duration.between(before, after).toMillis(); // .toWhatsoever()
API is awesome, highly readable and intuitive.
Classes are thread-safe too. !

Easiest way to use this function is to start by 'Recording a Macro'. Once you start recording, save the file to the location you want, with the name you want, and then of course set the file type, most likely 'Excel Macro Enabled Workbook' ~ 'XLSM'
Stop recording and you can start inspecting your code.
I wrote the code below which allows you to save a workbook using the path where the file was originally located, naming it as "Event [date in cell "A1"]"
Option Explicit
Sub SaveFile()
Dim fdate As Date
Dim fname As String
Dim path As String
fdate = Range("A1").Value
path = Application.ActiveWorkbook.path
If fdate > 0 Then
fname = "Event " & fdate
Application.ActiveWorkbook.SaveAs Filename:=path & "\" & fname, _
FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
Else
MsgBox "Chose a date for the event", vbOKOnly
End If
End Sub
Copy the code into a new module and then write a date in cell "A1" e.g. 01-01-2016 -> assign the sub to a button and run. [Note] you need to make a save file before this script will work, because a new workbook is saved to the default autosave location!
Per my understanding:
function range(start, end, step = 1) {
const _range = _start => f => {
if (_start < end) {
f(_start);
setTimeout(() => _range(_start + step)(f), 0);
}
}
return {
map: _range(start),
};
}
range(0, 50000).map(console.log);
This function doesn't raise the aforementioned concerns.

In the interests of completeness there are a couple of other solutions which (in my opinion) are more orthodox than solutions relying on the SqlDependency (and SqlTableDependency) classes. SqlDependency was originally designed to make refreshing distributed webserver caches easier, and so was built to a different set of requirements than if it were designed as an event producer.
There are broadly four options, some of which have not been covered here already:
Change tracking
Change tracking is a lightweight notification mechanism in SQL server. Basically, a database-wide version number is incremented with every change to any data. The version number is then written to the change tracking tables with a bit mask including the names of the columns which were changed. Note, the actual change is not persisted. The notification only contains the information that a particular data entity has changed. Further, because the change table versioning is cumulative, change notifications on individual items are not preserved and are overwritten by newer notifications. This means that if an entity changes twice, change tracking will only know about the most recent change.
In order to capture these changes in c#, polling must be used. The change tracking tables can be polled and each change inspected to see if is of interest. If it is of interest, it is necessary to then go directly to the data to retrieve the current state.
Change Data Capture
Source: https://technet.microsoft.com/en-us/library/bb522489(v=sql.105).aspx
Change data capture (CDC) is more powerful but most costly than change tracking. Change data capture will track and notify changes based on monitoring the database log. Because of this CDC has access to the actual data which has been changed, and keeps a record of all individual changes.
Similarly to change tracking, in order to capture these changes in c#, polling must be used. However, in the case of CDC, the polled information will contain the change details, so it's not strictly necessary to go back to the data itself.
Triggers to queues
Source: https://code.msdn.microsoft.com/Service-Broker-Message-e81c4316
This technique depends on triggers on the tables from which notifications are required. Each change will fire a trigger, and the trigger will write this information to a service broker queue. The queue can then be connected to via C# using the Service Broker Message Processor (sample in the link above).
Unlike change tracking or CDC, triggers to queues do not rely on polling and thereby provides realtime eventing.
CLR
This is a technique I have seen used, but I would not recommend it. Any solution which relies on the CLR to communicate externally is a hack at best. The CLR was designed to make writing complex data processing code easier by leveraging C#. It was not designed to wire in external dependencies like messaging libraries. Furthermore, CLR bound operations can break in clustered environments in unpredictable ways.
This said, it is fairly straightforward to set up, as all you need to do is register the messaging assembly with CLR and then you can call away using triggers or SQL jobs.
In summary...
It has always been a source of amazement to me that Microsoft has steadfastly refused to address this problem space. Eventing from database to code should be a built-in feature of the database product. Considering that Oracle Advanced Queuing combined with the ODP.net MessageAvailable event provided reliable database eventing to C# more than 10 years ago, this is woeful from MS.
The upshot of this is that none of the solutions listed to this question are very nice. They all have technical drawbacks and have a significant setup cost. Microsoft if you're listening, please sort out this sorry state of affairs.

These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".
The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.
ffmpeg
vs the fake oneFor a while both Libav and FFmpeg separately developed their own version of ffmpeg
.
Libav then renamed their bizarro ffmpeg
to avconv
to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv
instead of their counterfeit version of ffmpeg
. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.
This message was removed upstream when the fake "ffmpeg
" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.
In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1
. Unfortunately the new "deprecated" message has caused additional user confusion.
Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg
is back in the repositories again.
To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.
If you are using avconv
then you are using Libav. If you are using ffmpeg
you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.
Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h
header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg
or avconv
and viewing the console output.
ffmpeg
The real ffmpeg
is in the repository, so you can install it with:
apt-get install ffmpeg
Your options are:
ffmpeg
,ffmpeg
,These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.
Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg
from the repository.
For an interesting blog article on the situation, as well as a discussion about the main technical differences between the projects, see The FFmpeg/Libav situation.

Have you tried using a icon font like http://fortawesome.github.io/Font-Awesome/
Bootstrap comes with their own library, but it doesn't have as many icons as Font Awesome.
In my case, this is what resolved:
import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonProperty;
@JsonFormat(shape = JsonFormat.Shape.OBJECT)
public enum PeriodEnum {
DAILY(1),
WEEKLY(2),
;
private final int id;
PeriodEnum(int id) {
this.id = id;
}
public int getId() {
return id;
}
public String getName() {
return this.name();
}
@JsonCreator
public static PeriodEnum fromJson(@JsonProperty("name") String name) {
return valueOf(name);
}
}
Serializes and deserializes the following json:
{
"id": 2,
"name": "WEEKLY"
}
I hope it helps!

In my case this Microsoft.Owin.Host.SystemWeb package is present in the project.
But below two tags are not present in web.config.
<add key="owin:AutomaticAppStartup" value="true" />
<add key="owin:appStartup" value="namespace.className.methodName" />
after adding them it works smoothly.
Actually, you are quite right when it comes to header/footer. Here is some basic information on how each of the major HTML5 tags can/should be used (I suggest reading the full source linked at the bottom):
section – Used for grouping together thematically-related content. Sounds like a div element, but it’s not. The div has no semantic meaning. Before replacing all your div’s with section elements, always ask yourself: “Is all of the content related?”
aside – Used for tangentially related content. Just because some content appears to the left or right of the main content isn’t enough reason to use the aside element. Ask yourself if the content within the aside can be removed without reducing the meaning of the main content. Pullquotes are an example of tangentially related content.
header – There is a crucial difference between the header element and the general accepted usage of header (or masthead). There’s usually only one header or ‘masthead’ in a page. In HTML5 you can have as many as you want. The spec defines it as “a group of introductory or navigational aids”. You can use a header in any section on your site. In fact, you probably should use a header within most of your sections. The spec describes the section element as “a thematic grouping of content, typically with a heading.”
nav – Intended for major navigation information. A group of links grouped together isn’t enough reason to use the nav element. Site-wide navigation, on the other hand belongs in a nav element.
footer – Sounds like its a description of the position, but its not. Footer elements contain informations about its containing element: who wrote it, copyright, links to related content, etc. Whereas we usually have one footer for an entire document, HTML5 allows us to also have footer within sections.
Source: https://clzd.me/html5-section-aside-header-nav-footer-elements-not-as-obvious-as-they-sound/
Additionally, here's a description on article
, not found in the source above:
article – Used for element that specifies independent, self-contained content. An article should make sense on its own. Before replacing all your div’s with article elements, always ask yourself: “Is it possible to read it independently from the rest of the web site?”
tmp = df.groupby(['A'])['c'].transform('mean')
is like
tmp1 = df.groupby(['A']).agg({'c':'mean'})
tmp = df['A'].map(tmp1['c'])
or
tmp1 = df.groupby(['A'])['c'].mean()
tmp = df['A'].map(tmp1)
You can always try Manage Docker as a non-root user
paragraph in the https://docs.docker.com/install/linux/linux-postinstall/ docs.
After doing this also if the problem persists then you can run the following command to solve it:
sudo chmod 666 /var/run/docker.sock
you can do like this.....the below example shows text box(user control) value changed
// Declare a delegate
public delegate void ValueChangedEventHandler(object sender, ValueChangedEventArgs e);
public partial class SampleUserControl : TextBox
{
public SampleUserControl()
{
InitializeComponent();
}
// Declare an event
public event ValueChangedEventHandler ValueChanged;
protected virtual void OnValueChanged(ValueChangedEventArgs e)
{
if (ValueChanged != null)
ValueChanged(this,e);
}
private void SampleUserControl_TextChanged(object sender, EventArgs e)
{
TextBox tb = (TextBox)sender;
int value;
if (!int.TryParse(tb.Text, out value))
value = 0;
// Raise the event
OnValueChanged( new ValueChangedEventArgs(value));
}
}
One can also use the Flask Debug Toolbar extension to get more detailed information embedded in rendered pages.
from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension
import logging
app = Flask(__name__)
app.debug = True
app.secret_key = 'development key'
toolbar = DebugToolbarExtension(app)
@app.route('/')
def index():
logging.warning("See this message in Flask Debug Toolbar!")
return "<html><body></body></html>"
Start the application as follows:
FLASK_APP=main.py FLASK_DEBUG=1 flask run
5. Something else - there must be other solutions out there?
You're right, there is! And it is called JWT (JSON Web Tokens).
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA.
I highly recommend looking into JWTs. They're a much simpler solution to the problem when compared against alternative solutions.
I have just used dompdf and the code was a little different but it worked.
Here it is:
require_once("./pdf/dompdf_config.inc.php");
$files = glob("./pdf/include/*.php");
foreach($files as $file) include_once($file);
$html =
'<html><body>'.
'<p>Put your html here, or generate it with your favourite '.
'templating system.</p>'.
'</body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$output = $dompdf->output();
file_put_contents('Brochure.pdf', $output);
Only difference here is that all of the files in the include directory are included.
Other than that my only suggestion would be to specify a full directory path for writing the file rather than just the filename.
I stumbled across this old question and I think the easiest approach is still missing.
You can use rio
to import all excel sheets with just one line of code.
library(rio)
data_list <- import_list("test.xls")
If you're a fan of the tidyverse
, you can easily import them as tibbles by adding the setclass
argument to the function call.
data_list <- import_list("test.xls", setclass = "tbl")
Suppose they have the same format, you could easily row bind them by setting the rbind
argument to TRUE
.
data_list <- import_list("test.xls", setclass = "tbl", rbind = TRUE)
There is no out of the box DateTime picker for WPF..

$about->first()->id
or
$stm->first()->title
and your problem is sorted out.
document.getScroll = function() {
if (window.pageYOffset != undefined) {
return [pageXOffset, pageYOffset];
} else {
var sx, sy, d = document,
r = d.documentElement,
b = d.body;
sx = r.scrollLeft || b.scrollLeft || 0;
sy = r.scrollTop || b.scrollTop || 0;
return [sx, sy];
}
}
returns an array with two integers- [scrollLeft, scrollTop]
That is not possible with a normal query since the in
clause needs separate values and not a single value containing a comma separated list. One solution would be a dynamic query
declare @myList varchar(100)
set @myList = '(1,2,5,7,10)'
exec('select * from DBTable where id IN ' + @myList)
I had this Exception in the following situation.

and the name and path of my application class ("start-class") was wrong.
Yep, why not?
fs.Write(myByteArray, 0, myByteArray.Length);
I had the same problem, so I wrote this my self. This solution is differentiated from other answers because it can deserialize in to multiple levels.
Just send JSON string in to deserializeToDictionary function it will return non strongly-typed Dictionary<string, object>
object.
Old code
private Dictionary<string, object> deserializeToDictionary(string jo)
{
var values = JsonConvert.DeserializeObject<Dictionary<string, object>>(jo);
var values2 = new Dictionary<string, object>();
foreach (KeyValuePair<string, object> d in values)
{
// if (d.Value.GetType().FullName.Contains("Newtonsoft.Json.Linq.JObject"))
if (d.Value is JObject)
{
values2.Add(d.Key, deserializeToDictionary(d.Value.ToString()));
}
else
{
values2.Add(d.Key, d.Value);
}
}
return values2;
}
Ex: This will return Dictionary<string, object>
object of a Facebook JSON response.
Test
private void button1_Click(object sender, EventArgs e)
{
string responsestring = "{\"id\":\"721055828\",\"name\":\"Dasun Sameera Weerasinghe\",\"first_name\":\"Dasun\",\"middle_name\":\"Sameera\",\"last_name\":\"Weerasinghe\",\"username\":\"dasun\",\"gender\":\"male\",\"locale\":\"en_US\", hometown: {id: \"108388329191258\", name: \"Moratuwa, Sri Lanka\",}}";
Dictionary<string, object> values = deserializeToDictionary(responsestring);
}
Note: hometown further deserilize into a
Dictionary<string, object>
object.
Update
My old answer works great if there is no array on JSON string. This one further deserialize in to a List<object>
if an element is an array.
Just send a JSON string in to deserializeToDictionaryOrList function it will return non strongly-typed Dictionary<string, object>
object or List<object>
.
private static object deserializeToDictionaryOrList(string jo,bool isArray=false)
{
if (!isArray)
{
isArray = jo.Substring(0, 1) == "[";
}
if (!isArray)
{
var values = JsonConvert.DeserializeObject<Dictionary<string, object>>(jo);
var values2 = new Dictionary<string, object>();
foreach (KeyValuePair<string, object> d in values)
{
if (d.Value is JObject)
{
values2.Add(d.Key, deserializeToDictionary(d.Value.ToString()));
}
else if (d.Value is JArray)
{
values2.Add(d.Key, deserializeToDictionary(d.Value.ToString(), true));
}
else
{
values2.Add(d.Key, d.Value);
}
}
return values2;
}else
{
var values = JsonConvert.DeserializeObject<List<object>>(jo);
var values2 = new List<object>();
foreach (var d in values)
{
if (d is JObject)
{
values2.Add(deserializeToDictionary(d.ToString()));
}
else if (d is JArray)
{
values2.Add(deserializeToDictionary(d.ToString(), true));
}
else
{
values2.Add(d);
}
}
return values2;
}
}

I recommend using React.createRef()
and ref=this.elementRef
to get the DOM element reference instead of ReactDOM.findDOMNode(this)
. This way you can get the reference to the DOM element as an instance variable.
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
class MenuItem extends Component {
constructor(props) {
super(props);
this.elementRef = React.createRef();
}
handleNVFocus = event => {
console.log('Focused: ' + this.props.menuItem.caption.toUpperCase());
}
componentDidMount() {
this.elementRef.addEventListener('nv-focus', this.handleNVFocus);
}
componentWillUnmount() {
this.elementRef.removeEventListener('nv-focus', this.handleNVFocus);
}
render() {
return (
<element ref={this.elementRef} />
)
}
}
export default MenuItem;
In Eclipse, try Project > Open Project and select the projects to be opened.

IF(E2="suspended",IF(ISBLANK(F2),3,-2))))),-2)
Adding to @romanb brilliant answer.
This adds a little overhead in migration, because you obviously cannot create a field with not null constraint and with no default value.
// this up() migration is autogenerated, please modify it to your needs
$this->abortIf($this->connection->getDatabasePlatform()->getName() != "postgresql");
//lets add property without not null contraint
$this->addSql("ALTER TABLE tablename ADD property BOOLEAN");
//get the default value for property
$object = new Object();
$defaultValue = $menuItem->getProperty() ? "true":"false";
$this->addSql("UPDATE tablename SET property = {$defaultValue}");
//not you can add constraint
$this->addSql("ALTER TABLE tablename ALTER property SET NOT NULL");
With this answer, I encourage you to think why do you need the default value in the database in the first place? And usually it is to allow creating objects with not null constraint.
I believe running from Eclipse, if you're using "myconf.properties" as the relative path, You file structure should look somehting like this
ProjectRoot
src
bin
myconf.properties
Eclipse will look for the the file in the project root dir if no other dirs are specified in the file path
It is impossible to safely escape a string without a DB connection. mysql_real_escape_string()
and prepared statements need a connection to the database so that they can escape the string using the appropriate character set - otherwise SQL injection attacks are still possible using multi-byte characters.
If you are only testing, then you may as well use mysql_escape_string()
, it's not 100% guaranteed against SQL injection attacks, but it's impossible to build anything safer without a DB connection.
Use HTML5 Local Storage. you can store and use the data anytime you please.
<script>
// Store
localStorage.setItem("lastname", "Smith");
// Retrieve
var data = localStorage.getItem("lastname");

SQLite has a printf
function which does exactly that:
SELECT printf('%s-%.2d-%.4d', col1, col2, col3) FROM mytable
Open command prompt, type "systeminfo" and press enter. Your system may take few mins to get the information. In the result page you will find an entry as "System Installation Date". That is the date of windows installation. This process works in XP ,Win7 and also on win8.
If your instance is down, you are look for version information in alert.log

Look in the MySQL config file C:\xampp\mysql\bin\my.ini
.
At the top of that file are some comments:
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
There it tells you where to find your .my.cnf
file.
I'm using Mac OS and to write multiple lines in a SH Script following code worked for me
#! /bin/bash

And to access a variable we can use
$FILE_NAME
""" >> $FILE_NAME
cat $FILE_NAME
Please don't forget to assign chmod as required to the script file. I have used

Luckily, C# has no C/C++-style preprocessor - only conditional compilation and pragmas (and possibly something else I cannot recall) are supported. Unfortunatelly, C# has no metaprogramming capabilities (this may actually relate to your question to some extent).
You don't necessarily need to use the range function, you can simply do list[::-1] which should return the list in reversed order swiftly, without using any additions.
The proposed answers are great. Just would like to suggest an improvement to handle the case of null list using Optional.ofNullable
, new feature in Java 8:
List<String> carsFiltered = Optional.ofNullable(cars)
.orElseGet(Collections::emptyList)
.stream()
.filter(Objects::nonNull)
.collect(Collectors.toList());
So, the full answer will be:
List<String> carsFiltered = Optional.ofNullable(cars)
.orElseGet(Collections::emptyList)
.stream()
.filter(Objects::nonNull) //filtering car object that are null
.map(Car::getName) //now it's a stream of Strings
.filter(Objects::nonNull) //filtering null in Strings
.filter(name -> name.startsWith("M"))
.collect(Collectors.toList()); //back to List of Strings
Use the write()-Method of the Popup's document to put your markup there:
$.post(url, function (data) {
var w = window.open('about:blank');
w.document.open();
w.document.write(data);
w.document.close();
});
You can also do:
array = numpy.append(array, value)
Note that the numpy.append()
method returns a new object, so if you want to modify your initial array, you have to write: array = ...
void Fun(int *Pointer)
{
//if you want to manipulate the content of the pointer:
*Pointer=10;
//Here we are changing the contents of Pointer to 10
}
* before the pointer means the content of the pointer (except in declarations!)
& before the pointer (or any variable) means the address
EDIT:
int someint=15;
//to call the function
Fun(&someint);
//or we can also do
int *ptr;
ptr=&someint;
Fun(ptr);
The problem lies in position: static
. Static means don't do anyting at all with the position. position: absolute
is what you want. Centering the element is still tricky though. The following should work:
#whatever {
position: absolute;
bottom: 0px;
margin-right: auto;
margin-left: auto;
left: 0px;
right: 0px;
}
or
#whatever {
position: absolute;
bottom: 0px;
margin-right: auto;
margin-left: auto;
left: 50%;
transform: translate(-50%, 0);
}
But I recommend the first method. I used centering techniques from this answer: How to center absolutely positioned element in div?
To solve the issue, you are using the z-index on the footer and header, but you forgot about the position, if a z-index is to be used, the element must have a position:
Add to your footer and header this CSS:
position: relative;
EDITED:
Also noticed that the background image on the #backstretch has a negative z-index, don't use that, some browsers get really weird...
Remove From the #backstretch:
z-index: -999999;
Read a little bit about Z-Index here!
If you created your database following this tutorial: https://msdn.microsoft.com/en-au/data/jj193542.aspx
... then this might work:
.mdf
and .ldf
files in your project directoryNSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
height, @"user[height]",
weight, @"user[weight]",
nil];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:
[NSURL URLWithString:@"http://localhost:8080/"]];
[client postPath:@"/mypage.php" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *text = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"Response: %@", text);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"%@", [error localizedDescription]);
}];
The bottom statement is equivalent to:
.half {
flex-grow: 0;
flex-shrink: 0;
flex-basis: 50%;
}
Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.
Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.
I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)
For example if I had an application source code structure that looked like this:
Then I would do:
javadoc -d "C:\docs" -sourcepath "C:\b2b" -subpackages com
And that should create javadocs for source code of the com package, and all subpackages (recursively), found inside the "C:\b2b" directory.
There is little to be added to Garrett's great answer, but pandas also has a scatter
method. Using that, it's as easy as
df = pd.DataFrame(np.random.randn(10,2), columns=['col1','col2'])
df['col3'] = np.arange(len(df))**2 * 100 + 100
df.plot.scatter('col1', 'col2', df['col3'])
Look at this code, it can help you to get out of the loop fast!
foreach (var name in parent.names)
{
if (name.lastname == null)
{
Violated = true;
this.message = "lastname reqd";
break;
}
else if (name.firstname == null)
{
Violated = true;
this.message = "firstname reqd";
break;
}
}
Use this script instead:
@taskkill/f /im test.exe >nul 2>&1
@pause
What the 2>&1
part actually does, is that it redirects the stderr
output to stdout
. I will explain it better below:
Kill the task "test.exe". Redirect stderr
to stdout
. Then, redirect stdout
to nul
.
Show the pause message Press any key to continue . . .
until someone presses a key.
NOTE: The @
symbol is hiding the prompt for each command. You can save up to 8 bytes this way.
The shortest version of your script could be:
@taskkill/f /im test.exe >nul 2>&1&pause
The &
character is used for redirection the first time, and for separating the commands the second time.
An @
character is not needed twice in a line. This code is just 40 bytes, despite the one you've posted being 49 bytes! I actually saved 9 bytes. For a cleaner code look above.
You probably have allProviders
typed as object[]
as well. And property country
does not exist on object
. If you don't care about typing, you can declare both allProviders
and countryProviders
as Array<any>
:
let countryProviders: Array<any>;
let allProviders: Array<any>;
If you do want static type checking. You can create an interface for the structure and use it:
interface Provider {
region: string,
country: string,
locale: string,
company: string
}
let countryProviders: Array<Provider>;
let allProviders: Array<Provider>;
Thats what i am using try it.

Similar Question here
I'll repost my response and propose a merge:
Output UTC seems to be the subject of some confusion -- people seem to gravitate toward moment.js.
Borrowing from this answer, you could do something like this (i.e. use a convert function that creates the date with the UTC constructor) without moment.js:
controller
var app1 = angular.module('app1',[]);
app1.controller('ctrl',['$scope',function($scope){
var toUTCDate = function(date){
var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
return _utc;
};
var millisToUTCDate = function(millis){
return toUTCDate(new Date(millis));
};
$scope.toUTCDate = toUTCDate;
$scope.millisToUTCDate = millisToUTCDate;
}]);
template
<html ng-app="app1">
<head>
<script data-require="angular.js@*" data-semver="1.2.12" src="http://code.angularjs.org/1.2.12/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body>
<div ng-controller="ctrl">
<div>
utc {{millisToUTCDate(1400167800) | date:'dd-M-yyyy H:mm'}}
</div>
<div>
local {{1400167800 | date:'dd-M-yyyy H:mm'}}
</div>
</div>
</body>
</html>
here's plunker to play with it
Also note that with this method, if you use the 'Z' from Angular's date filter, it seems it will still print your local timezone offset.

You can do it like this, but sorry my english is not good enough.
First, get home base url with this simple code..
I've tested this code on my local server and public and the result is good.
<?php
function home_base_url(){
// first get http protocol if http or https
$base_url = (isset($_SERVER['HTTPS']) &&
$_SERVER['HTTPS']!='off') ? 'https://' : 'http://';
// get default website root directory
$tmpURL = dirname(__FILE__);
// when use dirname(__FILE__) will return value like this "C:\xampp\htdocs\my_website",
//convert value to http url use string replace,
// replace any backslashes to slash in this case use chr value "92"
$tmpURL = str_replace(chr(92),'/',$tmpURL);
// now replace any same string in $tmpURL value to null or ''
// and will return value like /localhost/my_website/ or just /my_website/
$tmpURL = str_replace($_SERVER['DOCUMENT_ROOT'],'',$tmpURL);
// delete any slash character in first and last of value
$tmpURL = ltrim($tmpURL,'/');
$tmpURL = rtrim($tmpURL, '/');
// check again if we find any slash string in value then we can assume its local machine
if (strpos($tmpURL,'/')){
// explode that value and take only first value
$tmpURL = explode('/',$tmpURL);
$tmpURL = $tmpURL[0];
}
// now last steps
// assign protocol in first value
if ($tmpURL !== $_SERVER['HTTP_HOST'])
// if protocol its http then like this
$base_url .= $_SERVER['HTTP_HOST'].'/'.$tmpURL.'/';
else
// else if protocol is https
$base_url .= $tmpURL.'/';
// give return value
return $base_url;
}
?>
// and test it
echo home_base_url();
output will like this :
local machine : http://localhost/my_website/ or https://myhost/my_website
public : http://www.my_website.com/ or https://www.my_website.com/
use home_base_url
function at index.php
of your website and define it
and then you can use this function to load scripts, css and content via url like
<?php
echo '<script type="text/javascript" src="'.home_base_url().'js/script.js"></script>'."\n";
?>
will create output like this :
<script type="text/javascript" src="http://www.my_website.com/js/script.js"></script>
and if this script works fine,,!
// the index of each item in fieldNames must correspond to
// the correct index in resultItems
