Because an interface is just a contract. And a class is actually a container for data.
In compact edition will take size automatically for datetime data type i.e. (8) so no need to set size of field and generate error for this operation...
Permitting a nested object :

I am trying to set a JPanel's background using an image, however, every example I find seems to suggest extending the panel with its own class
yes you will have to extend JPanel
and override the paintcomponent(Graphics g)
function to do so.
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(bgImage, 0, 0, null);
}
I have been looking for a way to simply add the image without creating a whole new class and within the same method (trying to keep things organized and simple).
You can use other component which allows to add image as icon directly e.g. JLabel
if you want.
ImageIcon icon = new ImageIcon(imgURL);
JLabel thumb = new JLabel();
thumb.setIcon(icon);
But again in the bracket trying to keep things organized and simple !! what makes you to think that just creating a new class will lead you to a messy world ?
{
"number" : ["1","2","3"],
"alphabet" : ["a", "b", "c"]
}
The OP left out some crucial information from the question and only put it in a comment to an answer.
I need to initialize after declaring, because will be different depending on a condition, I mean something like this int myArray[SIZE]; if(condition1) { myArray{x1, x2, x3, ...} } else if(condition2) { myArray{y1, y2, y3, ...} } . . and so on...
With this in mind, all of the possible arrays will need to be stored into data somewhere anyhow, so no memcpy is needed (or desired), only a pointer and a 2d array are required.
//static global since some compilers build arrays from instruction data
//... notably not const though so they can later be modified if needed
#define SIZE 8
static int myArrays[2][SIZE] = {{0,1,2,3,4,5,6,7},{7,6,5,4,3,2,1,0}};
static inline int *init_myArray(_Bool conditional){
return myArrays[conditional];
}
// now you can use:
//int *myArray = init_myArray(1 == htons(1)); //any boolean expression
The not-inlined version gives this resulting assembly on x86_64:
init_myArray(bool):
movzx eax, dil
sal rax, 5
add rax, OFFSET FLAT:myArrays
ret
myArrays:
.long 0
.long 1
.long 2
.long 3
.long 4
.long 5
.long 6
.long 7
.long 7
.long 6
.long 5
.long 4
.long 3
.long 2
.long 1
.long 0
For additional conditionals/arrays, just change the 2 in myArrays to the desired number and use similar logic to get a pointer to the right array.
SupressFinalize
tells the system that whatever work would have been done in the finalizer has already been done, so the finalizer doesn't need to be called. From the .NET docs:
Objects that implement the IDisposable interface can call this method from the IDisposable.Dispose method to prevent the garbage collector from calling Object.Finalize on an object that does not require it.
In general, most any Dispose()
method should be able to call GC.SupressFinalize()
, because it should clean up everything that would be cleaned up in the finalizer.
SupressFinalize
is just something that provides an optimization that allows the system to not bother queuing the object to the finalizer thread. A properly written Dispose()
/finalizer should work properly with or without a call to GC.SupressFinalize()
.
For Elasticbeanstalk environments, you can apply a key-value pair to a running instance like this:
There is a jquery print area. I've been using it for some time now.
$(".printMe").click(function(){
$("#outprint").printArea({ mode: 'popup', popClose: true });
});
I got the problem like you so I decide to write small tool to help me out. Please check ExcelDiff_Tools. It comes with several key points:

The below steps for using Android OpenCV sdk in Android Studio. This is a simplified version of this(1) SO answer.
Step (6) is since Android studio expects native libs in app/src/main/jniLibs
instead of older libs
folder. For those new to Android OpenCV, don't miss below steps
static{ System.loadLibrary("opencv_java"); }
(Note: for OpenCV version 3 at this step you should instead load the library opencv_java3
.)OpenCV written is in C/C++. Java wrappers are
First Option:
OPEN package.json and add "--port port-no" in "serve" section.
Just like below, I have done it.
{
"name": "app-name",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve --port 8090",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
}
Second Option: If You want through command prompt
npm run serve --port 8090
try this:
/////// Controller post and get simple text value
[HttpPost]
public string Contact(string message)
{
return "<h1>Hi,</h1>we got your message, <br />" + message + " <br />Thanks a lot";
}
//// in the view add reference to the Javascript (jQuery) files
@section Scripts{
<script src="~/Scripts/modernizr-2.6.2.js"></script>
<script src="~/Scripts/jquery-1.8.2.intellisense.js"></script>
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
}
/// then add the Post method as following:
<script type="text/javascript">
/// post and get text value
$("#send").on("click", function () {
$.post('', { message: $('#msg').val() })
//// empty post('') means post to the default controller,
///we are not pacifying different action or controller
/// however we can define a url as following:
/// var url = "@(Url.Action("GetDataAction", "GetDataController"))"
.done(function (response) {
$("#myform").html(response);
})
.error(function () { alert('Error') })
.success(function () { alert('OK') })
return false;
});
Now let's say you want to do it using $.Ajax and JSON:
// Post JSON data add using System.Net;
[HttpPost]
public JsonResult JsonFullName(string fname, string lastname)
{
var data = "{ \"fname\" : \"" + fname + " \" , \"lastname\" : \"" + lastname + "\" }";
//// you have to add the JsonRequestBehavior.AllowGet
//// otherwise it will throw an exception on run-time.
return Json(data, JsonRequestBehavior.AllowGet);
}
Then, inside your view: add the event click on a an input of type button, or even a from submit: Just make sure your JSON data is well formatted.
$("#jsonGetfullname").on("click", function () {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "@(Url.Action("JsonFullName", "Home"))",
data: "{ \"fname\" : \"Mahmoud\" , \"lastname\" : \"Sayed\" }",
dataType: "json",
success: function (data) {
var res = $.parseJSON(data);
$("#myform").html("<h3>Json data: <h3>" + res.fname + ", " + res.lastname)
},
error: function (xhr, err) {
alert("readyState: " + xhr.readyState + "\nstatus: " + xhr.status);
alert("responseText: " + xhr.responseText);
}
})
});
With Spring Boot JPA, use the below code in your application.properties file and obviously you can modify timezone to your choice
spring.jpa.properties.hibernate.jdbc.time_zone = UTC
Then in your Entity class file,
@Column
private LocalDateTime created;
To access properties and methods of a parent class use the base
keyword. So in your child class LoadData()
method you would do this:
public class Child : Parent
{
public void LoadData()
{
base.MyMethod(); // call method of parent class
base.CurrentRow = 1; // set property of parent class
// other stuff...
}
}
Note that you would also have to change the access modifier of your parent MyMethod()
to at least protected
for the child class to access it.
You are checking whether the string contains all illegal characters. Change the ||
s to &&
s.
something like below
var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
var friends= db.Friends.Where(f=>idList.Contains(f.ID)).ToList();
friends.ForEach(a=>a.msgSentBy='1234');
db.SaveChanges();
}
you can update multiple fields as below
friends.ForEach(a =>
{
a.property1 = value1;
a.property2 = value2;
});
I just had this issue as well in a PhoneGap application. I solved it by using the JavaScript function getTime()
in the following manner:
var currentTime = new Date();
var n = currentTime.getTime();
postUrl = "http://www.example.com/test.php?nocache="+n;
$.post(postUrl, callbackFunction);
I wasted a few hours figuring this out. It would have been nice of Apple to notify developers of this caching issue.
multipart/form-data
Note. Please consult RFC2388 for additional information about file uploads, including backwards compatibility issues, the relationship between "multipart/form-data" and other content types, performance issues, etc.
Please consult the appendix for information about security issues for forms.
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
The content type "multipart/form-data" follows the rules of all multipart MIME data streams as outlined in RFC2045. The definition of "multipart/form-data" is available at the [IANA] registry.
A "multipart/form-data" message contains a series of parts, each representing a successful control. The parts are sent to the processing agent in the same order the corresponding controls appear in the document stream. Part boundaries should not occur in any of the data; how this is done lies outside the scope of this specification.
As with all multipart MIME types, each part has an optional "Content-Type" header that defaults to "text/plain". User agents should supply the "Content-Type" header, accompanied by a "charset" parameter.
application/x-www-form-urlencoded
This is the default content type. Forms submitted with this content type must be encoded as follows:
Control names and values are escaped. Space characters are replaced by +', and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by
%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., %0D%0A').
The control names/values are listed in the order they appear in the document. The name is separated from the value by
=' and name/value pairs are separated from each other by `&'.
application/x-www-form-urlencoded
the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be:
MyVariableOne=ValueOne&MyVariableTwo=ValueTwo
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
To be able to install wheel files with a simple doubleclick on them you can do one the following:
1) Run two commands in command line under administrator privileges:
assoc .whl=pythonwheel
ftype pythonwheel=cmd /c pip.exe install "%1" ^& pause
2) Alternatively, they can be copied into a wheel.bat
file and executed with 'Run as administrator' checkbox in the properties.
PS pip.exe is assumed to be in the PATH.
Update:
(1) Those can be combined in one line:
assoc .whl=pythonwheel& ftype pythonwheel=cmd /c pip.exe install -U "%1" ^& pause
(2) Syntax for .bat files is slightly different:
assoc .whl=pythonwheel& ftype pythonwheel=cmd /c pip.exe install -U "%%1" ^& pause
Also its output can be made more verbose:
@assoc .whl=pythonwheel|| echo Run me with administrator rights! && pause && exit 1
@ftype pythonwheel=cmd /c pip.exe install -U "%%1" ^& pause || echo Installation error && pause && exit 1
@echo Installation successfull & pause
see my blog post for details.
The trick is to use $ sign before single quotes. It also works for cut and other tools.
grep $'\t' sample.txt
SELECT terms.*
FROM terms JOIN terms_relation ON id=term_id
WHERE taxonomy='categ'
If you by any chance are using Wordpress to develop your app (it's actually a convenient way to get authorization, info pages etc even for very simple stuff), you can use the following snippet:
$response = wp_remote_post( $url, array('body' => $parameters));
if ( is_wp_error( $response ) ) {
// $response->get_error_message()
} else {
// $response['body']
}
It uses different ways of making the actual HTTP request, depending on what is available on the web server. For more details, see the HTTP API documentation.
If you don't want to develop a custom theme or plugin to start the Wordpress engine, you can just do the following in an isolated PHP file in the wordpress root:
require_once( dirname(__FILE__) . '/wp-load.php' );
// ... your code
It won't show any theme or output any HTML, just hack away with the Wordpress APIs!
Try
let s= new Date().toLocaleString();_x000D_
_x000D_
console.log(s);
_x000D_
I think a more reliable way of closing a connection is to tell the sever explicitly to close it in a way compliant with HTTP specification:
HTTP/1.1 defines the "close" connection option for the sender to signal that the connection will be closed after completion of the response. For example,
Connection: close
in either the request or the response header fields indicates that the connection SHOULD NOT be considered `persistent' (section 8.1) after the current request/response is complete.
The Connection: close
header is added to the actual request:
r = requests.post(url=url, data=body, headers={'Connection':'close'})
You can try this if you want to override
var newArray= [444,555,666];
var oldArray =[11,22,33];
oldArray.forEach((name, index) => oldArray [index] = newArray[index]);
console.log(newArray);
Most of the other answers use a loop to reduce the font-size until it fits on the div, this is VERY slow since the page needs to re-render the element each time the font changes size. I eventually had to write my own algorithm to make it perform in a way that allowed me to update its contents periodically without freezing the user browser. I added some other functionality (rotating text, adding padding) and packaged it as a jQuery plugin, you can get it at:
https://github.com/DanielHoffmann/jquery-bigtext
simply call
$("#text").bigText();
and it will fit nicely on your container.
See it in action here:
http://danielhoffmann.github.io/jquery-bigtext/
For now it has some limitations, the div must have a fixed height and width and it does not support wrapping text into multiple lines.
I will work on getting an option to set the maximum font-size.
Edit: I have found some more problems with the plugin, it does not handle other box-model besides the standard one and the div can't have margins or borders. I will work on it.
Edit2: I have now fixed those problems and limitations and added more options. You can set maximum font-size and you can also choose to limit the font-size using either width, height or both. I will work into accepting a max-width and max-height values in the wrapper element.
Edit3: I have updated the plugin to version 1.2.0. Major cleanup on the code and new options (verticalAlign, horizontalAlign, textAlign) and support for inner elements inside the span tag (like line-breaks or font-awesome icons.)
In addition to @James Iry's solution, it is also possible to accomplish this using a fold. I suspect that this solution is slightly faster than the tuple method (fewer garbage objects are created):
val list = List("this", "maps", "string", "to", "length")
val map = list.foldLeft(Map[String, Int]()) { (m, s) => m(s) = s.length }
If i say without loop, i can use GOTO
statement for delete large amount of records using sql server.
exa.
IsRepeat:
DELETE TOP (10000)
FROM <TableName>
IF @@ROWCOUNT > 0
GOTO IsRepeat
like this way you can delete large amount of data with smaller size of delete.
let me know if requires more information.
The other answers are all great/correct (the main difference is whether the DestTable
exists already (INSERT
), or doesn't exist yet (SELECT ... INTO
))
You may prefer to use INSERT
(instead of SELECT ... INTO
), if you want to be able to COUNT(*)
the rows that have been inserted so far.
Using SELECT COUNT(*) ... WITH NOLOCK
is a simple/crude technique that may help you check the "progress" of the INSERT
; helpful if it's a long-running insert, as seen in this answer).
[If you use...]
INSERT DestTable SELECT ... FROM SrcTable
...then yourSELECT COUNT(*) from DestTable WITH (NOLOCK)
query would work.
For your specific data, you can use
Select col1, col2, LTRIM(RTRIM(SUBSTRING(
STUFF(col3, CHARINDEX('|', col3,
PATINDEX('%|Client Name =%', col3) + 14), 1000, ''),
PATINDEX('%|Client Name =%', col3) + 14, 1000))) col3
from Table01

select col3='Clent ID = 4356hy|Client Name = B B BOB|Client Phone = 667-444-2626|Client Fax = 666-666-0151|Info = INF8888877 -MAC333330554/444400800'

CHARINDEX:
SQL Server Execution Times (1):
CPU time = 5656 ms, elapsed time = 6418 ms.
SQL Server Execution Times (2):
CPU time = 5813 ms, elapsed time = 6114 ms.
SQL Server Execution Times (3):
CPU time = 5672 ms, elapsed time = 6108 ms.
PATINDEX:
SQL Server Execution Times (1):
CPU time = 5906 ms, elapsed time = 6296 ms.
SQL Server Execution Times (2):
CPU time = 5860 ms, elapsed time = 6404 ms.
SQL Server Execution Times (3):
CPU time = 6109 ms, elapsed time = 6301 ms.
Conclusion
The timings for CharIndex and PatIndex for 700k calls are within 3.5% of each other, so I don't think it would matter whichever is used. I use them interchangeably when both can work.
you can just use
ls > filenames.txt
(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd
to go to that folder first, or you can ls ~/docs > filenames.txt
To catch Guzzle errors you can do something like this:
try {
$response = $client->get('/not_found.xml')->send();
} catch (Guzzle\Http\Exception\BadResponseException $e) {
echo 'Uh oh! ' . $e->getMessage();
}
... but, to be able to "log" or "resend" your request try something like this:
// Add custom error handling to any request created by this client
$client->getEventDispatcher()->addListener(
'request.error',
function(Event $event) {
//write log here ...
if ($event['response']->getStatusCode() == 401) {
// create new token and resend your request...
$newRequest = $event['request']->clone();
$newRequest->setHeader('X-Auth-Header', MyApplication::getNewAuthToken());
$newResponse = $newRequest->send();
// Set the response object of the request without firing more events
$event['response'] = $newResponse;
// You can also change the response and fire the normal chain of
// events by calling $event['request']->setResponse($newResponse);
// Stop other events from firing when you override 401 responses
$event->stopPropagation();
}
});
... or if you want to "stop event propagation" you can overridde event listener (with a higher priority than -255) and simply stop event propagation.
$client->getEventDispatcher()->addListener('request.error', function(Event $event) {
if ($event['response']->getStatusCode() != 200) {
// Stop other events from firing when you get stytus-code != 200
$event->stopPropagation();
}
});
thats a good idea to prevent guzzle errors like:
request.CRITICAL: Uncaught PHP Exception Guzzle\Http\Exception\ClientErrorResponseException: "Client error response
in your application.
ES6 of the day here;
const json_getAllKeys = data => (
data.reduce((keys, obj) => (

And yes it can be written in very long one line;
const json_getAllKeys = data => data.reduce((keys, obj) => keys.concat(Object.keys(obj).filter(key => keys.indexOf(key) === -1)), [])
EDIT: Returns all first order keys if the input is of type array of objects
CONTAINS
is for a Full Text Indexed field - if not, then use LIKE
I hate bumping old articles but this is the first result for this in google search and I had a heck of a time with this problem (even with the support of you guys). So here goes nothing...
Hopefully my solution will help those that also was confused.
namespace MyApplication.WebAPI.Controllers
{
public class BaseController : ApiController
{
public T SendResponse<T>(T response, HttpStatusCode statusCode = HttpStatusCode.OK)
{
if (statusCode != HttpStatusCode.OK)
{
// leave it up to microsoft to make this way more complicated than it needs to be
// seriously i used to be able to just set the status and leave it at that but nooo... now
// i need to throw an exception
var badResponse =
new HttpResponseMessage(statusCode)
{
Content = new StringContent(JsonConvert.SerializeObject(response), Encoding.UTF8, "application/json")
};
throw new HttpResponseException(badResponse);
}
return response;
}
}
}
and then just inherit from the BaseController
[RoutePrefix("api/devicemanagement")]
public class DeviceManagementController : BaseController
{...
and then using it
[HttpGet]
[Route("device/search/{property}/{value}")]
public SearchForDeviceResponse SearchForDevice(string property, string value)
{
//todo: limit search property here?
var response = new SearchForDeviceResponse();
var results = _deviceManagementBusiness.SearchForDevices(property, value);
response.Success = true;
response.Data = results;
var statusCode = results == null || !results.Any() ? HttpStatusCode.NoContent : HttpStatusCode.OK;
return SendResponse(response, statusCode);
}
You need to use <br>
instead of \r\n
. For this you can use built in function call nl2br
So your code should be like this
$message = nl2br("CCCC\r\nCCCC CCCC \r CCC \n CCC \r\n CCC \n\r CCCC");
For right labels use ax.yaxis.set_label_position("right")
, i.e.:
f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
ax.yaxis.set_label_position("right")
plt.plot([2,3,4,5])
ax.set_xlabel("$x$ /mm")
ax.set_ylabel("$y$ /mm")
plt.show()
Another reason is when you have a SerialPort opened on a USB COM port, and then the USB device is unplugged. Because the SerialPort was opened, the resource holds a reference to the previously connected port in the system's registry. The system's registry will then contain stale data, so the list of available ports will be wrong. Therefore the port must be closed.
Calling SerialPort.Close() on the port calls Dispose() on the object, but it remains in memory until garbage collection actually runs, causing the registry to remain stale until the garbage collector decides to release the resource.
From https://stackoverflow.com/a/58810699/8685342:
try
{
if (port != null)
port.Close(); //this will throw an exception if the port was unplugged
}
catch (Exception ex) //of type 'System.IO.IOException'
{
System.GC.Collect();
System.GC.WaitForPendingFinalizers();
}
port = null;
In your Post
model add two accessor methods like this:
public function getCreatedAtAttribute($date)
{
return Carbon\Carbon::createFromFormat('Y-m-d H:i:s', $date)->format('Y-m-d');
}
public function getUpdatedAtAttribute($date)
{
return Carbon\Carbon::createFromFormat('Y-m-d H:i:s', $date)->format('Y-m-d');
}
Now every time you use these properties from your model to show a date these will be presented differently, just the date without the time, for example:
$post = Post::find(1);
echo $post->created_at; // only Y-m-d formatted date will be displayed
So you don't need to change the original type in the database. to change the type
in your database you need to change it to Date
from Timestamp
and you need to do it from your migration (If your using at all) or directly into your database if you are not using migration. The timestamps()
method adds these fields (using Migration) and to change these fields during the migration you need to remove the timestamps()
method and use date()
instead, for example:
$table->date('created_at');
$table->date('updated_at');

block to prevent a resource leak when an exception occurs.
To use the with
statement, create a class with the following methods:
def __enter__(self)
def __exit__(self, exc_type, exc_value, traceback)
In your example above, you'd use
class Package:
def __init__(self):
self.files = []
def __enter__(self):
return self
# ...
def __exit__(self, exc_type, exc_value, traceback):
for file in self.files:
os.unlink(file)
Then, when someone wanted to use your class, they'd do the following:
with Package() as package_obj:
# use package_obj
The variable package_obj will be an instance of type Package (it's the value returned by the __enter__
method). Its __exit__
method will automatically be called, regardless of whether or not an exception occurs.
You could even take this approach a step further. In the example above, someone could still instantiate Package using its constructor without using the with
clause. You don't want that to happen. You can fix this by creating a PackageResource class that defines the __enter__
and __exit__
methods. Then, the Package class would be defined strictly inside the __enter__
method and returned. That way, the caller never could instantiate the Package class without using a with
statement:
class PackageResource:
def __enter__(self):
class Package:
...
self.package_obj = Package()
return self.package_obj
def __exit__(self, exc_type, exc_value, traceback):
self.package_obj.cleanup()
You'd use this as follows:
with PackageResource() as package_obj:
# use package_obj
Most simple approach in Template driven forms for min/max validation with out using reactive forms and building any directive, would be to use pattern attribute of html. This has already been explained and answered here please look https://stackoverflow.com/a/63312336/14069524
The Reason
You are not opening the page through a server, like Apache, so when the browser tries to obtain the resource it thinks it is from a separate domain, which is not allowed. Though some browsers do allow it.
The Solution
Run inetmgr and host your page locally and browse as http://localhost:portnumber/PageName.html or through a web server like Apache, nginx, node etc.
Alternatively use a different browser No error was shown when directly opening the page using Firefox and Safari. It comes only for Chrome and IE(xx).
If you are using code editors like Brackets, Sublime or Notepad++, those apps handle this error automatically.
Configuring a button (or any widget) in Tkinter is done by calling a configure method "config"
To change the size of a button called button1
you simple call
button1.config( height = WHATEVER, width = WHATEVER2 )
If you know what size you want at initialization these options can be added to the constructor.
button1 = Button(self, text = "Send", command = self.response1, height = 100, width = 100)
You can use this code line in view(form)
<?= $form->field($model, 'hidden1')->hiddenInput(['value'=>'your_value'])->label(false) ?>
Please refere this as example
If your need to pass currant date and time as hidden input : Model attribute is 'created_on' and its value is retrieve from date('Y-m-d H:i:s') , just like:"2020-03-10 09:00:00"
<?= $form->field($model, 'created_on')->hiddenInput(['value'=>date('Y-m-d H:i:s')])->label(false) ?>
If you want a list of columns of a certain type, you can use groupby
:
>>> df = pd.DataFrame([[1, 2.3456, 'c', 'd', 78]], columns=list("ABCDE"))
>>> df
A B C D E
0 1 2.3456 c d 78
[1 rows x 5 columns]
>>> df.dtypes
A int64
B float64
C object
D object
E int64
dtype: object
>>> g = df.columns.to_series().groupby(df.dtypes).groups
>>> g
{dtype('int64'): ['A', 'E'], dtype('float64'): ['B'], dtype('O'): ['C', 'D']}
>>> {k.name: v for k, v in g.items()}
{'object': ['C', 'D'], 'int64': ['A', 'E'], 'float64': ['B']}
If you want to get only ID in array, can use array_map:
$data = array_map(function($object){
return $object->ID;
}, $data);
With that, return an array with ID in every pos.
You need to use the proper git URL:
pip install git+https://github.com/jkbr/httpie.git#egg=httpie
Also see the VCS Support section of the pip documentation.
Don’t forget to include the egg=<projectname>
part to explicitly name the project; this way pip can track metadata for it without having to have run the setup.py script.
Bundle was failing to install json -v '1.8.1' and deleting my Gemfile.lock and running bundle again solved this issue for me.
You have to set the associatedEmployee on the Vehicle before persisting the Employee.
Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);
newEmployee.setVehicles(vehicles);
Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);
One easy way to map that country name that you have to an int
to be used in the setImageResource
method is:
int id = getResources().getIdentifier(lowerCountryCode, "drawable", getPackageName());
setImageResource(id);
But you should really try to use different folders resources for the countries that you want to support.
I have also been through this problem,
First i tried setting my password of root to blank using command :
SET PASSWORD FOR root@localhost=PASSWORD('');
But don't be happy , PHPMYADMIN uses 127.0.0.1 not localhost , i know you would say both are same but that is not the case , use the command mentioned underneath and you are done.
SET PASSWORD FOR [email protected]=PASSWORD('');
Just replace localhost with 127.0.0.1 and you are done .
The JS solution works great but I would advise on a server side solution. Some of the sites I checked had this issue of the entire page going blank and only the year being seen once in a while.
The reason for this was the document.write actually wrote over the entire document.
I asked my friend to implement a server side solution and it worked for him. The simple code in php
<?php echo date('Y'); ?>
Enjoy!
Given its name, I think the standard way should be delete
:
import numpy as np
A = np.delete(A, 1, 0) # delete second row of A
B = np.delete(B, 2, 0) # delete third row of B
C = np.delete(C, 1, 1) # delete second column of C
According to numpy's documentation page, the parameters for numpy.delete
are as follow:
numpy.delete(arr, obj, axis=None)
arr
refers to the input array, obj
refers to which sub-arrays (e.g. column/row no. or slice of the array) andaxis
refers to either column wise (axis = 1
) or row-wise (axis = 0
) delete operation.each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.
For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.
http:..../somelink?componentId=123
would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123
The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

Sending signal 0 to a pid will raise an OSError exception if the pid is not running, and do nothing otherwise.
import os
def check_pid(pid):
""" Check For the existence of a unix pid. """
try:
os.kill(pid, 0)
except OSError:
return False
else:
return True
You can do it more simply, guaranteeing that your .gitconfig
is left in a meaningful state:
git push -u hub master
when pushing, or:
git branch -u hub/master
(This will set the remote for the currently checked-out branch to hub/master
)
git branch --set-upstream-to hub/master
(This will set the remote for the branch named branch_name
to hub/master
)
git branch branch_name --set-upstream-to hub/master
v1.7.x
or earlieryou must use --set-upstream
:
git branch --set-upstream master hub/master
I have found a weird problem with .gitignore. Everything was in place and seemed correct. The only reason why my .gitignore was "ignored" was, that the line-ending was in Mac-Format (\r). So after saving the file with the correct line-ending (in vi using :set ff=unix) everything worked like a charm!
awk '!seen[$0]++' file.txt
seen
is an associative-array that Awk will pass every line of the file to. If a line isn't in the array then seen[$0]
will evaluate to false. The !
is the logical NOT operator and will invert the false to true. Awk will print the lines where the expression evaluates to true. The ++
increments seen
so that seen[$0] == 1
after the first time a line is found and then seen[$0] == 2
, and so on.
Awk evaluates everything but 0
and ""
(empty string) to true. If a duplicate line is placed in seen
then !seen[$0]
will evaluate to false and the line will not be written to the output.
In [92]: (myseries==7).argmax()
Out[92]: 3
This works if you know 7 is there in advance. You can check this with (myseries==7).any()
Another approach (very similar to the first answer) that also accounts for multiple 7's (or none) is
In [122]: myseries = pd.Series([1,7,0,7,5], index=['a','b','c','d','e'])
In [123]: list(myseries[myseries==7].index)
Out[123]: ['b', 'd']
Recursion means a function calls repeatedly
It uses system stack to accomplish it's task. As stack uses LIFO approach and when a function is called the controlled is moved to where function is defined which has it is stored in memory with some address, this address is stored in stack
Secondly, it reduces a time complexity of a program.
Though bit off-topic,a bit related. Must read. : Recursion vs Iteration
You can use:
<script type="text/javascript">
function prepareFrame() {
var ifrm = document.createElement("iframe");
ifrm.setAttribute("src", "http://google.com/");
ifrm.style.width = "640px";
ifrm.style.height = "480px";
document.body.appendChild(ifrm);
}
</script>

To write inline styling use:
<div style="height: 100px;">
asdfashdjkfhaskjdf
</div>
Inline styling serves a purpose however, it is not recommended in most situations.
The more "proper" solution, would be to make a separate CSS sheet, include it in your HTML document, and then use either an ID or a class to reference your div.
if you have the file structure:
index.html
>>/css/
>>/css/styles.css
Then in your HTML document between <head>
and </head>
write:
<link href="css/styles.css" rel="stylesheet" />
Then, change your div structure to be:
<div id="someidname" class="someclassname">
asdfashdjkfhaskjdf
</div>
In css, you can reference your div from the ID or the CLASS.
To do so write:
.someclassname { height: 100px; }
OR
#someidname { height: 100px; }
Note that if you do both, the one that comes further down the file structure will be the one that actually works.
For example... If you have:
.someclassname { height: 100px; }
.someclassname { height: 150px; }
Then in this situation the height will be 150px.
EDIT:
To answer your secondary question from your edit, probably need overflow: hidden;
or overflow: visible;
. You could also do this:
<div class="span12">
<div style="height:100px;">
asdfashdjkfhaskjdf
</div>
</div>
Another type of solution would be to autogenerate the nginx conf files via Jinja2 templates from ansible. The advantage of this is easy deployment to a cloud environment, and easy to replicate on multiple dev machines
In rails 4 you can now use a css and sass helper image-url:
div.logo {background-image: image-url("logo.png");}
If your background images aren't showing up consider looking at how you're referencing them in your stylesheets.
This paragraph from the FptWebRequest class reference might be of interest to you:
The URI may be relative or absolute. If the URI is of the form "ftp://contoso.com/%2fpath" (%2f is an escaped '/'), then the URI is absolute, and the current directory is /path. If, however, the URI is of the form "ftp://contoso.com/path", first the .NET Framework logs into the FTP server (using the user name and password set by the Credentials property), then the current directory is set to /path.

After a lot of searching ,i found the problem was in my project dll file .i cleaned and rebuild my project when there were compilation errors ... simple solution is to remove all compilation errors in all pages either by removing contents or commenting lines ,then clean and rebuild your project ... this will sort out your problem ..
You can also implement a contains
method with foldLeft
, it's pretty awesome. I just love foldLeft algorithms.
For example:
object ContainsWithFoldLeft extends App {
val list = (0 to 10).toList
println(contains(list, 10)) //true
println(contains(list, 11)) //false
def contains[A](list: List[A], item: A): Boolean = {
list.foldLeft(false)((r, c) => c.equals(item) || r)
}
}
I've faced the exactly same problem but I've fixed it with another approache.
Using Ubuntu 18.04, first disable systemd-resolved
service.
sudo systemctl disable systemd-resolved.service
Stop the service
sudo systemctl stop systemd-resolved.service
Then, remove the link to /run/systemd/resolve/stub-resolv.conf
in /etc/resolv.conf
sudo rm /etc/resolv.conf
Add a manually created resolv.conf
in /etc/
sudo vim /etc/resolv.conf
Add your prefered DNS server there
nameserver 208.67.222.222
I've tested this with success.
with pandas, it is much easier, for example.
assuming you have the following data as CSV and let's call it test.txt
/ test.csv
(you know CSV is a sort of text file )
a,b,c,d
1,2,3,4
5,6,7,8
now using pandas
import pandas as pd
df = pd.read_csv("./text.txt")
df_to_doct = df.to_dict()
for each row, it would be
df.to_dict(orient='records')
and that's it.
I also landed in a similar situation. Use interactive rebase using the command below and while selecting, drop 3rd commit.
git rebase -i remote/branch
This worked for me ::-
mysql --host=hostNameorIp --user=username --password=password
or
mysql --host=hostNameorIp --user=username --password=password database_name
At the beginning of your file you set raw_input

There are various methods for collision resolution.Some of them are Separate Chaining,Open addressing,Robin Hood hashing,Cuckoo Hashing etc.
Java uses Separate Chaining for resolving collisions in Hash tables.Here is a great link to how it happens: http://javapapers.com/core-java/java-hashtable/
If you want to center elements inside a div and don't care about division size you could use Flex power. I prefer using flex and don't use exact size for elements.
<div class="outer flex">
<div class="inner">
This is the inner Content
</div>
</div>
As you can see Outer div is Flex container and Inner must be Flex item that specified with flex: 1 1 auto;
for better understand you could see this simple sample. http://jsfiddle.net/QMaster/hC223/
Hope this help.

In response to your first question: Yes, you have to run a server app to send the messages, as well as a client app to receive them.
In response to your second question: Yes, every application needs its own API key. This key is for your server app, not the client.
So by adding the #!/bin/sh

It also helped me in fixing an issue where I was executing bash script from Jenkins master on my Linux slave. By just adding #!/bin/bash

SQL Server 2012 above, I prefer use format() function, more simplify.

There's another option not cited here which is included in the GNU Make book by Stallman and McGrath (see http://www.chemie.fu-berlin.de/chemnet/use/info/make/make_7.html). It provides the example:
archive.a: ...
ifneq (,$(findstring t,$(MAKEFLAGS)))
+touch archive.a
+ranlib -t archive.a
else
ranlib archive.a
endif
It involves verifying if a given parameter appears in MAKEFLAGS
. For example .. suppose that you're studying about threads in c++11 and you've divided your study across multiple files (class01
, ... , classNM
) and you want to: compile then all and run individually or compile one at a time and run it if a flag is specified (-r
, for instance). So, you could come up with the following Makefile
:
CXX=clang++-3.5
CXXFLAGS = -Wall -Werror -std=c++11
LDLIBS = -lpthread
SOURCES = class01 class02 class03
%: %.cxx
$(CXX) $(CXXFLAGS) -o [email protected] $^ $(LDLIBS)
ifneq (,$(findstring r, $(MAKEFLAGS)))
./[email protected]
endif
all: $(SOURCES)
.PHONY: clean
clean:
find . -name "*.out" -delete
Having that, you'd:
make -r class02
; make
or make all
;make -r
(suppose that all of them contain some certain kind of assert stuff and you just want to test them all)you can also add comment by pressing Ctrl+shift+/ and shift+ / for one line.
This is what I did to integrate Identity with an existing database.
Create a sample MVC project with MVC template. This has all the code needed for Identity implementation - Startup.Auth.cs, IdentityConfig.cs, Account Controller code, Manage Controller, Models and related views.
Install the necessary nuget packages for Identity and OWIN. You will get an idea by seeing the references in the sample Project and the answer by @Sam
Copy all these code to your existing project. Please note don't forget to add the "DefaultConnection" connection string for Identity to map to your database. Please check the ApplicationDBContext class in IdentityModel.cs where you will find the reference to "DefaultConnection" connection string.
This is the SQL script I ran on my existing database to create necessary tables:

Check and solve any remaining errors and you are done. Identity will handle the rest :)
The diffrence is very simple:
Long version
If you want to have better readability, use Math.floor
. But if you want to minimize it, use tilde ~~
.
There are a lot of sources on the internet saying Math.floor
is faster, but sometimes ~~
. I would not recommend you think about speed because it is not going to be noticed when running the code. Maybe in tests etc, but no human can see a diffrence here. What would be faster is to use ~~
for a faster load time.
Short version
~~
is shorter/takes less space. Math.floor
improves the readability. Sometimes tilde is faster, sometimes Math.floor
is faster, but it is not noticeable.

Because it's a function definition and it needs to know what parameters the function accepts, and in what order. It can't just look at the expression and use the variables names in that, because some of those names you might want to use existing local or global variable values for, and even if it did that, it wouldn't know what order it should expect to get them.
Your error message means that Tk is calling your lambda with one argument, while your lambda is written to accept no arguments. If you don't need the argument, just accept one and don't use it. (Demosthenex has the code, I would have posted it but was beaten to it.)
Adding a space before the EOF delimiter allows to avoid cmd:
- shell: |
cat <<' EOF'
This is a test.

A little late to the party, but here is a comparison of the time taken to copy a file using various file copy methods. I looped in through the methods for 10 times and took an average. File transfer using IO streams seem to be the worst candidate:
Here are the methods:
private static long fileCopyUsingFileStreams(File fileToCopy, File newFile) throws IOException {
FileInputStream input = new FileInputStream(fileToCopy);
FileOutputStream output = new FileOutputStream(newFile);
byte[] buf = new byte[1024];
int bytesRead;
long start = System.currentTimeMillis();
while ((bytesRead = input.read(buf)) > 0)
{
output.write(buf, 0, bytesRead);
}
long end = System.currentTimeMillis();
input.close();
output.close();
return (end-start);
}
private static long fileCopyUsingNIOChannelClass(File fileToCopy, File newFile) throws IOException
{
FileInputStream inputStream = new FileInputStream(fileToCopy);
FileChannel inChannel = inputStream.getChannel();
FileOutputStream outputStream = new FileOutputStream(newFile);
FileChannel outChannel = outputStream.getChannel();
long start = System.currentTimeMillis();
inChannel.transferTo(0, fileToCopy.length(), outChannel);
long end = System.currentTimeMillis();
inputStream.close();
outputStream.close();
return (end-start);
}
private static long fileCopyUsingApacheCommons(File fileToCopy, File newFile) throws IOException
{
long start = System.currentTimeMillis();
FileUtils.copyFile(fileToCopy, newFile);
long end = System.currentTimeMillis();
return (end-start);
}
private static long fileCopyUsingNIOFilesClass(File fileToCopy, File newFile) throws IOException
{
Path source = Paths.get(fileToCopy.getPath());
Path destination = Paths.get(newFile.getPath());
long start = System.currentTimeMillis();
Files.copy(source, destination, StandardCopyOption.REPLACE_EXISTING);
long end = System.currentTimeMillis();
return (end-start);
}
The only drawback what I can see while using NIO channel class is that I still can't seem to find a way to show intermediate file copy progress.
To represent the text below in JavaScript:
"'http://example.com'"
Use:
"\"'http://example.com'\""
Or:
'"\'http://example.com\'"'
Note that: We always need to escape the quote that we are surrounding the string with using \
JS Fiddle: http://jsfiddle.net/efcwG/
General Pointers:
Example
var answer="It's alright";
var answer="He is called 'Johnny'";
var answer='He is called "Johnny"';
Example
var answer='It\'s alright';
var answer="He is called \"Johnny\"";
str.join()
works fine in Python 3, you just need to get the order of the arguments correct
>>> str.join('.', ('a', 'b', 'c'))
'a.b.c'
You can use sp_lock
(and sp_lock2
), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks
:
select
object_name(p.object_id) as TableName,
resource_type, resource_description
from
sys.dm_tran_locks l
join sys.partitions p on l.resource_associated_entity_id = p.hobt_id
There is an easier way to find a min integer in array list:
int min = array.get(0);
for (int i : array){
min = min < i ? min : i;
}
I had the same error. I created a directory under views direcotry named users
and created an index.blade.php
file in it. When calling this file you should write users.index
to indicate your path. Or just create index.blade.php
file under views. hope this will help someone who gets the same problem
Some of the other posts are confused about which dimension is which. Here's an NUNIT test that shows how 2D arrays work in C#
[Test]
public void ArraysAreRowMajor()
{
var myArray = new int[2,3]
{
{1, 2, 3},
{4, 5, 6}
};
int rows = myArray.GetLength(0);
int columns = myArray.GetLength(1);
Assert.AreEqual(2,rows);
Assert.AreEqual(3,columns);
Assert.AreEqual(1,myArray[0,0]);
Assert.AreEqual(2,myArray[0,1]);
Assert.AreEqual(3,myArray[0,2]);
Assert.AreEqual(4,myArray[1,0]);
Assert.AreEqual(5,myArray[1,1]);
Assert.AreEqual(6,myArray[1,2]);
}
You may not place the deprecated non-block-scoped stage
(as in the original question) inside parallel
.
As of JENKINS-26107, stage
takes a block argument. You may put parallel
inside stage
or stage
inside parallel
or stage
inside stage
etc. However visualizations of the build are not guaranteed to support all nestings; in particular
stage
nesting.parallel
branches inside a top-level stage, but currently no more.JENKINS-27394, if implemented, would display arbitrarily nested stage
s.
Here's a quick and dirty ctypes tutorial.
First, write your C library. Here's a simple Hello world example:
#include <stdio.h>
void myprint(void);
void myprint()
{
printf("hello world\n");
}
Now compile it as a shared library (mac fix found here):
$ gcc -shared -Wl,-soname,testlib -o testlib.so -fPIC testlib.c
# or... for Mac OS X
$ gcc -shared -Wl,-install_name,testlib.so -o testlib.so -fPIC testlib.c
Then, write a wrapper using ctypes:
import ctypes
testlib = ctypes.CDLL('/full/path/to/testlib.so')
testlib.myprint()
Now execute it:
$ python testlibwrapper.py
And you should see the output
Hello world
$
If you already have a library in mind, you can skip the non-python part of the tutorial. Make sure ctypes can find the library by putting it in /usr/lib
or another standard directory. If you do this, you don't need to specify the full path when writing the wrapper. If you choose not to do this, you must provide the full path of the library when calling ctypes.CDLL()
.
This isn't the place for a more comprehensive tutorial, but if you ask for help with specific problems on this site, I'm sure the community would help you out.
PS: I'm assuming you're on Linux because you've used ctypes.CDLL('libc.so.6')
. If you're on another OS, things might change a little bit (or quite a lot).
Arrays.equals
is not enough for a comparator, you can not check the map contain the data. I copy the code from Arrays.equals
, modified to build a Comparator
.
class ByteArrays{
public static <T> SortedMap<byte[], T> newByteArrayMap() {
return new TreeMap<>(new ByteArrayComparator());
}
public static SortedSet<byte[]> newByteArraySet() {
return new TreeSet<>(new ByteArrayComparator());
}
static class ByteArrayComparator implements Comparator<byte[]> {
@Override
public int compare(byte[] a, byte[] b) {
if (a == b) {
return 0;
}
if (a == null || b == null) {
throw new NullPointerException();
}
int length = a.length;
int cmp;
if ((cmp = Integer.compare(length, b.length)) != 0) {
return cmp;
}
for (int i = 0; i < length; i++) {
if ((cmp = Byte.compare(a[i], b[i])) != 0) {
return cmp;
}
}
return 0;
}
}
}
I just want to add, for anyone who uses:
String x=Integer.toBinaryString()
to get a String of Binary numbers and wants to convert that string into an int. If you use
int y=Integer.parseInt(x)
you will get a NumberFormatException error.
What I did to convert String x to Integers, was first converted each individual Char in the String x to a single Char in a for loop.
char t = (x.charAt(z));
I then converted each Char back into an individual String,
String u=String.valueOf(t);
then Parsed each String into an Integer.
Id figure Id post this, because I took me a while to figure out how to get a binary such as 01010101 into Integer form.
This post has a reasonable answer:
CMakeLists.txt.in
:
cmake_minimum_required(VERSION 2.8.2)

)
CMakeLists.txt
:
# Download and unpack googletest at configure time

# Prevent GoogleTest from overriding our compiler/linker options
# when building with Visual Studio
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
# Add googletest directly to our build. This adds
# the following targets: gtest, gtest_main, gmock
# and gmock_main
add_subdirectory(${CMAKE_BINARY_DIR}/googletest-src
${CMAKE_BINARY_DIR}/googletest-build)
# The gtest/gmock targets carry header search path
# dependencies automatically when using CMake 2.8.11 or
# later. Otherwise we have to add them here ourselves.
if (CMAKE_VERSION VERSION_LESS 2.8.11)
include_directories("${gtest_SOURCE_DIR}/include"
"${gmock_SOURCE_DIR}/include")
endif()
# Now simply link your own targets against gtest, gmock,
# etc. as appropriate
However it does seem quite hacky. I'd like to propose an alternative solution - use Git submodules.
cd MyProject/dependencies/gtest
git submodule add https://github.com/google/googletest.git
cd googletest
git checkout release-1.8.0
cd ../../..
git add *
git commit -m "Add googletest"
Then in MyProject/dependencies/gtest/CMakeList.txt
you can do something like:
cmake_minimum_required(VERSION 3.3)
if(TARGET gtest) # To avoid diamond dependencies; may not be necessary depending on you project.
return()
endif()
add_subdirectory("googletest")
I haven't tried this extensively yet but it seems cleaner.
Edit: There is a downside to this approach: The subdirectory might run install()
commands that you don't want. This post has an approach to disable them but it was buggy and didn't work for me.
Edit 2: If you use add_subdirectory("googletest" EXCLUDE_FROM_ALL)
it seems means the install()
commands in the subdirectory aren't used by default.
The difference is substantial for many applications. If you are currently constrained by storage throughput, particularly when reading data, BitLocker will slow you down.
It would be useful to compare with other software based whole disk or whole partition encryption like TrueCrypt (which has the advantage if you dual boot with Linux since it works for both Windows and Linux).
A much better option is to use hardware encryption, which is available in many SSDs as well as in Hitachi 7200 RPM HDD. The performance of encrypted v. not is undetectable, and the encryption is invisible to operating systems. If you have a decent laptop, you can use the built-in security functions to generate and store the key, which your password unlocks from the encrypted key storage of the laptop.
Make your Project and Workspace to point to JDK7 which will resolve the issue. https://developers.google.com/eclipse/docs/jdk_compliance has given ways to modify Compliance and Facet level changes.

Instead of redis-cli
you can simply use nc
!
nc -v --ssl redis.mydomain.com 6380
Then submit the commands.

It's pretty simple and no cast required.
First copy the source range then paste-special on target range with Transpose:=True, short sample:
Option Explicit
Sub test()
Dim sourceRange As Range
Dim targetRange As Range
Set sourceRange = ActiveSheet.Range(Cells(1, 1), Cells(5, 1))
Set targetRange = ActiveSheet.Cells(6, 1)
sourceRange.Copy
targetRange.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=True
End Sub
The Transpose function takes parameter of type Varaiant and returns Variant.
Sub transposeTest()
Dim transposedVariant As Variant
Dim sourceRowRange As Range
Dim sourceRowRangeVariant As Variant
Set sourceRowRange = Range("A1:H1") ' one row, eight columns
sourceRowRangeVariant = sourceRowRange.Value
transposedVariant = Application.Transpose(sourceRowRangeVariant)
Dim rangeFilledWithTransposedData As Range
Set rangeFilledWithTransposedData = Range("I1:I8") ' eight rows, one column
rangeFilledWithTransposedData.Value = transposedVariant
End Sub
I will try to explaine the purpose of 'calling transpose twice'. If u have row data in Excel e.g. "a1:h1" then the Range("a1:h1").Value is a 2D Variant-Array with dimmensions 1 to 1, 1 to 8. When u call Transpose(Range("a1:h1").Value) then u get transposed 2D Variant Array with dimensions 1 to 8, 1 to 1. And if u call Transpose(Transpose(Range("a1:h1").Value)) u get 1D Variant Array with dimension 1 to 8.
First Transpose changes row to column and second transpose changes the column back to row but with just one dimension.
If the source range would have more rows (columns) e.g. "a1:h3" then Transpose function just changes the dimensions like this: 1 to 3, 1 to 8 Transposes to 1 to 8, 1 to 3 and vice versa.
Hope i did not confuse u, my english is bad, sorry :-).
Please check the following file
%SystemRoot%\system32\drivers\etc\host
The line which bind the host name with ip is probably missing a line which bind them togather
127.0.0.1 localhost
If the given line is missing. Add the line in the file
Could you also check your MySQL database's user table and tell us the host column value for the user which you are using. You should have user privilege for both the host "127.0.0.1" and "localhost" and use % as it is a wild char for generic host name.
To make it more interesting and to hopefully enable less hair pulling for someone else. Using python, built dictionary for a device which we can use curl to configure.
Problem: {"timezone":"+5"} //throws an error " 5"
Solution: {"timezone":"%2B"+"5"} //Works
So, in a nutshell:

json = JSONEncoder().encode(var)
subprocess.call(["curl",ipaddress,"-XPUT","-d","data="+json])

PHP way of getting text from span tag:
$spanText = $this->webDriver->findElement(WebDriverBy::xpath("//*[@id='specInformation']/tbody/tr[2]/td[1]/span[1]"))->getText();
A cleaner approach ( only for test environment) in httpcliet4.3.3 is as follows.
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext,SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
The following is what I learned by playing around with various options for forcing a TextView
to a single line (with and without the three dots).
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:text="one two three four five six seven eight nine ten" />
This just forces the text to one line. Any extra text is hidden.
Related:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:ellipsize="end"
android:text="one two three four five six seven eight nine ten" />
This cuts off the text that doesn't fit but lets users know that the text has been truncated by adding an ellipsis (the three dots).
Related:
<TextView
android:id="@+id/MarqueeText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:singleLine="true"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:text="one two three four five six seven eight nine ten" />
This makes the text scroll automatically across the TextView. Note that sometimes it needs to be set in code:
textView.setSelected(true);
Supposedly android:maxLines="1"
and android:singleLine="true"
should do basically the same thing and since singleLine is apparently deprecated I would prefer not to use it, but when I take it out, the marquee doesn't scroll anymore. Taking maxLines
out doesn't affect it, though.
Related:
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/horizontalScrollView">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:scrollHorizontally="true"
android:text="one two three four five six seven eight nine ten" />
</HorizontalScrollView>
This allows the user to manually scroll to see the whole line of text.
The simplest way I have found is to just set the container name in the docker-compose.yml
See container_name documentation. It is applicable to docker-compose v1+. It works for container to container, not from the host machine to container.
services:
dns:
image: phensley/docker-dns
container_name: affy
Now you should be able to access affy
from other containers using the container name. I had to do this for multiple redis servers in a development environment.
NOTE The solution works so long as you don't need to scale. Such as consistant individual developer environments.
If you want to have unique elements in your list, then why not use a set, if of course, order does not matter for you: -
>>> s = set()
>>> s.add(2)
>>> s.add(4)
>>> s.add(5)
>>> s.add(2)
>>> s
39: set([2, 4, 5])
If order is a matter of concern, then you can use: -
>>> def addUnique(l, num):
... if num not in l:
... l.append(num)
...
... return l
You can also find an OrderedSet
recipe, which is referred to in Python Documentation
echo '<p>'. get_the_category( $id )[0]->name .'</p>';
is what you maybe looking for.
Mozila Firefox says that onreadystatechange
is an alternative to DOMContentLoaded
.
// alternative to DOMContentLoaded
document.onreadystatechange = function () {
if (document.readyState == "complete") {
initApplication();
}
}
In DOMContentLoaded
the Mozila's doc says:
The DOMContentLoaded event is fired when the document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading (the load event can be used to detect a fully-loaded page).
I think load
event should be used for a full document+resources loading.
Another answer here also mentions since 2012 you can remove Remove cached login via How to remove cached server names from the Connect to Server dialog?. Just confirmed this delete in MRU list works fine in 2016 and 2017.
SQL Server Management Studio 2017 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\14.0\SqlStudio.bin
SQL Server Management Studio 2016 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\13.0\SqlStudio.bin
SQL Server Management Studio 2014 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\12.0\SqlStudio.bin
SQL Server Management Studio 2012 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\11.0\SqlStudio.bin
SQL Server Management Studio 2008 delete the file C:\Users\%username%\AppData\Roaming\Microsoft\Microsoft SQL Server\100\Tools\Shell\SqlStudio.bin
SQL Server Management Studio 2005 delete the file – same as above answer but the Vista path.
C:\Users\%username%\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat
These are profile paths for Vista / 7 / 8.
EDIT:
Note, AppData
is a hidden folder. You need to show hidden folders in explorer.
EDIT: You can simply press delete from the Server / User name drop down (confirmed to be working for SSMS v18.0). Original source from https://blog.sqlauthority.com/2013/04/17/sql-server-remove-cached-login-from-ssms-connect-dialog-sql-in-sixty-seconds-049/ which mentioned that this feature is available since 2012!
If it's only to check how a parameter is formatted in the result query, most DBMS's will allow querying literals from nothing. Thus:
Using cmd As SqlCommand = Connection.CreateCommand
cmd.CommandText = "SELECT @Value"
cmd.Parameters.AddWithValue("@Value", "myValue")
Return cmd.ExecuteScalar
End Using
That way you can see if quotes are doubled, etc.
strtok
is an overlooked function for this sort of thing. It is meant to be quite fast.
$s = '233718_This_is_a_string';
$firstPart = strtok( $s, '_' );
$allTheRest = strtok( '' );
Empty string like this will force the rest of the string to be returned.
NB if there was nothing at all after the '_' you would get a FALSE
value for $allTheRest
which, as stated in the documentation, must be tested with ===, to distinguish from other falsy values.
If you want to test the logic just don´t test it asynchronously.
For example to test this code which works on results of an asynchronous method.
public class Example {
private Dependency dependency;
public Example(Dependency dependency) {
this.dependency = dependency;
}
public CompletableFuture<String> someAsyncMethod(){
return dependency.asyncMethod()
.handle((r,ex) -> {
if(ex != null) {
return "got exception";
} else {
return r.toString();
}
});
}
}
public class Dependency {
public CompletableFuture<Integer> asyncMethod() {
// do some async stuff
}
}
In the test mock the dependency with synchronous implementation. The unit test is completely synchronous and runs in 150ms.
public class DependencyTest {
private Example sut;
private Dependency dependency;
public void setup() {
dependency = Mockito.mock(Dependency.class);;
sut = new Example(dependency);
}
@Test public void success() throws InterruptedException, ExecutionException {
when(dependency.asyncMethod()).thenReturn(CompletableFuture.completedFuture(5));
// When
CompletableFuture<String> result = sut.someAsyncMethod();
// Then
assertThat(result.isCompletedExceptionally(), is(equalTo(false)));
String value = result.get();
assertThat(value, is(equalTo("5")));
}
@Test public void failed() throws InterruptedException, ExecutionException {
// Given
CompletableFuture<Integer> c = new CompletableFuture<Integer>();
c.completeExceptionally(new RuntimeException("failed"));
when(dependency.asyncMethod()).thenReturn(c);
// When
CompletableFuture<String> result = sut.someAsyncMethod();
// Then
assertThat(result.isCompletedExceptionally(), is(equalTo(false)));
String value = result.get();
assertThat(value, is(equalTo("got exception")));
}
}
You don´t test the async behaviour but you can test if the logic is correct.
Here is an example that shows the differences, which will help with the explanation.
var s1 = new String("Avoid newing things where possible");
var s2 = "A string, in TypeScript of type 'string'";
var s3: string;
String
is the JavaScript String type, which you could use to create new strings. Nobody does this as in JavaScript the literals are considered better, so s2
in the example above creates a new string without the use of the new
keyword and without explicitly using the String
object.
string
is the TypeScript string type, which you can use to type variables, parameters and return values.
Additional notes...
Currently (Feb 2013) Both s1
and s2
are valid JavaScript. s3
is valid TypeScript.
Use of String
. You probably never need to use it, string literals are universally accepted as being the correct way to initialise a string. In JavaScript, it is also considered better to use object literals and array literals too:
var arr = []; // not var arr = new Array();
var obj = {}; // not var obj = new Object();
If you really had a penchant for the string, you could use it in TypeScript in one of two ways...
var str: String = new String("Hello world"); // Uses the JavaScript String object
var str: string = String("Hello World"); // Uses the TypeScript string type
Try Using DateTime::createFromFormat
$date = DateTime::createFromFormat('d/m/Y', "24/04/2012");
echo $date->format('Y-m-d');
Output
2012-04-24
EDIT:
If the date is 5/4/2010 (both D/M/YYYY or DD/MM/YYYY), this below method is used to convert 5/4/2010 to 2010-4-5 (both YYYY-MM-DD or YYYY-M-D) format.
$old_date = explode('/', '5/4/2010');
$new_data = $old_date[2].'-'.$old_date[1].'-'.$old_date[0];
OUTPUT:
2010-4-5
To identify which x86/x64 version of VC is needed:
Go to IIS Manager > Handler Mappings > right click then Edit *.php path. In the "Executable (optional)" field note in which version of Program Files is the php-cgi.exe installed.
Include <tchar.h>
which has the line:
#define _tWinMain wWinMain
defaultConfig {
ndk {
abiFilters "armeabi-v7a", "x86", "armeabi", "mips"

Android's default system path of your application database is /data/data/YOUR_PACKAGE/databases/YOUR_DB_NAME
Your logcat clearly says Failed to open database '/data/data/com.example.quotes/databasesQuotesdb'
Which means there is no file present on the given path or You have given the wrong path for the data file. As I can see there should be "/" after databases folder.
Your DB_PATH variable should end with a "/".
private static String DB_PATH = "/data/data/com.example.quotes/databases/";
Your correct path will be now "/data/data/com.example.quotes/databases/Quotesdb"
Well your solution above depends on the image being a jpeg file. For a general solution i used
$img = $_POST['image'];
$img = substr(explode(";",$img)[1], 7);
file_put_contents('img.png', base64_decode($img));
Vibur DBCP is another library for that purpose. Several examples showing how to configure it for use with Hibernate, Spring+Hibernate, or programatically, can be found on its website: http://www.vibur.org/
Also, see the disclaimer here.
A few points I find useful when applying this to my own plots:
fig.suptitle(title)
rather than plt.suptitle(title)
fig.tight_layout()
the title must be shifted with fig.subplots_adjust(top=0.88)
Example code taken from subplots demo in matplotlib docs and adjusted with a master title.
import matplotlib.pyplot as plt
import numpy as np
# Simple data to display in various forms
x = np.linspace(0, 2 * np.pi, 400)
y = np.sin(x ** 2)
fig, axarr = plt.subplots(2, 2)
fig.suptitle("This Main Title is Nicely Formatted", fontsize=16)
axarr[0, 0].plot(x, y)
axarr[0, 0].set_title('Axis [0,0] Subtitle')
axarr[0, 1].scatter(x, y)
axarr[0, 1].set_title('Axis [0,1] Subtitle')
axarr[1, 0].plot(x, y ** 2)
axarr[1, 0].set_title('Axis [1,0] Subtitle')
axarr[1, 1].scatter(x, y ** 2)
axarr[1, 1].set_title('Axis [1,1] Subtitle')
# # Fine-tune figure; hide x ticks for top plots and y ticks for right plots
plt.setp([a.get_xticklabels() for a in axarr[0, :]], visible=False)
plt.setp([a.get_yticklabels() for a in axarr[:, 1]], visible=False)
# Tight layout often produces nice results
# but requires the title to be spaced accordingly
fig.tight_layout()
fig.subplots_adjust(top=0.88)
plt.show()
As astander has mentioned, you can do that with a UDF. However, for large sets using a scalar function (as oppoosed to a inline-table function) the performance will stink as the function is evaluated row-by-row. As an alternative, you could expose the same results via a stored procedure executing a fixed query with placeholders which substitutes in your parameter values.
(Here's a somewhat dated but still relevant article on row-by-row processing for scalar UDFs.)
Edit: comments re. degrading performance adjusted to make it clear this applies to scalar UDFs.
This will work:
WebElement searchbox = driver.findElement(By.name("j_username"));
WebElement searchbox2 = driver.findElement(By.name("j_password"));
try {
FileInputStream file = new FileInputStream(new File("C:\\paulo.xls"));
HSSFWorkbook workbook = new HSSFWorkbook(file);
HSSFSheet sheet = workbook.getSheetAt(0);
for (int i=1; i <= sheet.getLastRowNum(); i++){
HSSFCell j_username = sheet.getRow(i).getCell(0)
HSSFCell j_password = sheet.getRow(i).getCell(0)
//Setting the Cell type as String
j_username.setCellType(j_username.CELL_TYPE_STRING)
j_password.setCellType(j_password.CELL_TYPE_STRING)
searchbox.sendKeys(j_username.toString());
searchbox2.sendKeys(j_password.toString());
searchbox.submit();
driver.manage().timeouts().implicitlyWait(10000, TimeUnit.MILLISECONDS);
}
workbook.close();
file.close();
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
}
For compiler which support __COUNTER__
, you can use them for simple (but large) state mashines.
#define START 0
#define END 1000
int run = 1;
state = START;
while(run)
{
switch (state)
{
case __COUNTER__:
//do something
state++;
break;
case __COUNTER__:
//do something
if (input)
state = END;
else
state++;
break;
.
.
.
case __COUNTER__:
//do something
if (input)
state = START;
else
state++;
break;
case __COUNTER__:
//do something
state++;
break;
case END:
//do something
run = 0;
state = START;
break;
default:
state++;
break;
}
}
The advantage of using __COUNTER__
instead of hard coded numbers is that you
can add states in the middle of other states, without renumbering everytime everything.
If the compiler doesnt support __COUNTER__
, in a limited way its posible to use with precaution __LINE__
//slightly improved code without using collection framework
package com.test;
public class TestClass {
private static Link last;
private static Link first;
public static void main(String[] args) {

Link.insert(i+5);
}
Link.printList();
//Deleting
Link.deletefromFirst();
Link.printList();
}
protected static class Link {
private int data;
private Link nextlink;
public Link(int d1) {
this.data = d1;
}
public static void insert(int d1) {
Link a = new Link(d1);
a.nextlink = null;
if (first != null) {
last.nextlink = a;
last = a;
} else {
first = a;
last = a;
}
System.out.println("Inserted -:"+d1);
}
public static void deletefromFirst() {
if(null!=first)
{
System.out.println("Deleting -:"+first.data);
first = first.nextlink;
}
else{
System.out.println("No elements in Linked List");
}
}
public static void printList() {
System.out.println("Elements in the list are");
System.out.println("-------------------------");
Link temp = first;
while (temp != null) {
System.out.println(temp.data);
temp = temp.nextlink;
}

For people who searched for php multidimensional array get values
and actually want to solve problem comes from getting one column value from a 2 dimensinal array (like me!), here's a much elegant way than using foreach
, which is array_column
For example, if I only want to get hotel_name
from the below array, and form to another array:
$hotels = [
[
'hotel_name' => 'Hotel A',
'info' => 'Hotel A Info',
],
[
'hotel_name' => 'Hotel B',
'info' => 'Hotel B Info',
]
];
I can do this using array_column
:
$hotel_name = array_column($hotels, 'hotel_name');
print_r($hotel_name); // Which will give me ['Hotel A', 'Hotel B']
For the actual answer for this question, it can also be beautified by array_column
and call_user_func_array('array_merge', $twoDimensionalArray);
Let's make the data in PHP:
$hotels = [
[
'hotel_name' => 'Hotel A',
'info' => 'Hotel A Info',
'rooms' => [
[
'room_name' => 'Luxury Room',
'bed' => 2,
'boards' => [
'board_id' => 1,
'price' => 200
]
],
[
'room_name' => 'Non Luxy Room',
'bed' => 4,
'boards' => [
'board_id' => 2,
'price' => 150
]
],
]
],
[
'hotel_name' => 'Hotel B',
'info' => 'Hotel B Info',
'rooms' => [
[
'room_name' => 'Luxury Room',
'bed' => 2,
'boards' => [
'board_id' => 3,
'price' => 900
]
],
[
'room_name' => 'Non Luxy Room',
'bed' => 4,
'boards' => [
'board_id' => 4,
'price' => 300
]
],
]
]
];
And here's the calculation:
$rooms = array_column($hotels, 'rooms');
$rooms = call_user_func_array('array_merge', $rooms);
$boards = array_column($rooms, 'boards');
foreach($boards as $board){
$board_id = $board['board_id'];
$price = $board['price'];
echo "Board ID is: ".$board_id." and price is: ".$price . "<br/>";
}
Which will give you the following result:
Board ID is: 1 and price is: 200
Board ID is: 2 and price is: 150
Board ID is: 3 and price is: 900
Board ID is: 4 and price is: 300
single/double quotes
and backslash
everywhere:
$ python -c 'exec("import sys\nfor i in range(10): print \"bob\"")'
Much better:
$ python -c '
> import sys
> for i in range(10):
> print "bob"
> '
Since you already seem to have solved the basic pointer address display, here's how you would check the address of a double pointer:
char **a;
char *b;
char c = 'H';
b = &c;
a = &b;
You would be able to access the address of the double pointer a
by doing:
printf("a points at this memory location: %p", a);
printf("which points at this other memory location: %p", *a);
I'm assuming the table has a primary key. First try to run a unlock tables command to see if that fixes it.
If all else fails you can alter the table to create a new primary key column with auto-increment and that should hopefully fix it. Once you're done you should be able to remove the column without any issues.
As always you want to make a backup before altering tables around. :)
Note: MySQL workbench cannot work without a primary key if that's your issue. However if you have a many to many table you can set both columns as primary keys which will let you edit the data.
For me general solution :)

The usual way is to use UPDATE:
UPDATE mytable
SET new_column = <expr containing old_column>
You should be able to do this is a single transaction.
You could use the DateTime.Ticks property, which is a long and universal storable, always increasing and usable on the compact framework as well. Just make sure your code isn't used after December 31st 9999 ;)
This should do the trick!
// convert object => json
$json = json_encode($myObject);
// convert json => object
$obj = json_decode($json);
Here's an example
$foo = new StdClass();
$foo->hello = "world";
$foo->bar = "baz";
$json = json_encode($foo);
echo $json;
//=> {"hello":"world","bar":"baz"}
print_r(json_decode($json));
// stdClass Object
// (
// [hello] => world
// [bar] => baz
// )
If you want the output as an Array instead of an Object, pass true
to json_decode
print_r(json_decode($json, true));
// Array
// (
// [hello] => world
// [bar] => baz
// )

Open your run console type: services.msc look for: mysql right click properties where is written "path to executable", click and move the cursor to the right until you see the directory of my.ini, it's written "defaults-file-". to reach it manually on your explore folders you have to enable the visualization of hidden elements (explore folder>top menu>visualize>visualize hidden elements)
as explained by this video
You could use JavaScript and trigger the hidden file input when the button input has been clicked.
http://jsfiddle.net/gregorypratt/dhyzV/ - simple
http://jsfiddle.net/gregorypratt/dhyzV/1/ - fancier with a little JQuery
Or, you could style a div directly over the file input and set pointer-events
in CSS to none to allow the click events to pass through to the file input that is "behind" the fancy div. This only works in certain browsers though; http://caniuse.com/pointer-events

Try using getTime
(mdn doc) :
var diff = Math.abs(date1.getTime() - date2.getTime()) / 3600000;
if (diff < 18) { /* do something */ }
Using Math.abs()
we don't know which date is the smallest. This code is probably more relevant :
var diff = (date1 - date2) / 3600000;
if (diff < 18) { array.push(date1); }
I was looking for something along what you wanted, but wanted to put it back into a variable.
So this is what I did
variable = ['hello this is x' x ', this is now y' y ', finally this is d:' d]
basically

Even though this answer is late, i have summarized the differences below,
Observable:
function
that takes an observer
and returns a function Observer: an object with next, error.
subscribe/unsubscribe
to its data stream, emit
next value to the observer, notify
the observer about errors
and
inform the observer about the stream completion
function to handle next value
,errors and
end of stream(ui events,http responses,data with web sockets).multiple values
over timecancel-able/retry-able
and supports operators such as map,filter,reduce
etc.Observable.create()
- returns Observable that can invoke methods on
-Observer Observable.from()
- converts an array or iterable into
-Observable Observable.fromEvent()
- converts an event into Observable
-Observable.fromPromise()
- converts a Promise into Observable
-Observable.range()
- returns a sequence of integers in the speci?ed rangePromise:
A promise represents a task that will finish in the future;
Promises become resolved by a value
;
Promises get rejected by exceptions;
Not cancellable
and it returns a single value
A promise expose a function (then)
-then returns a new promise
;
-allows for the attachment
of that will be executed based on
state
;
-handlers
are guaranteed
to execute in order attached
;
your event is triggered only once... so this code may work try this
$(".addproduct,.addproduct,.addproduct,.addproduct,.addproduct").click(function(){//do something fired 5 times});
I personally use the Jackson module for Kotlin that you can find here: jackson-module-kotlin.

For Bootstrap 4 you may have to use .modal-backdrop.show
and play around with !important
flag on both background-color
and opacity
.
E.g.
.modal-backdrop.show {
background-color: #f00;
opacity: 0.75;
}
They are just \r\n and \n
are variants.
\r\n

Using hardcoded indexes itself can be a mess.
In order to avoid that, Python offers a built-in object slice()
.
string = "my company has 1000$ on profit, but I lost 500$ gambling."
If we want to know how many money I got left.
Normal solution:
final = int(string[15:19]) - int(string[43:46])
print(final)
>>>500
Using slices:
EARNINGS = slice(15, 19)
LOSSES = slice(43, 46)
final = int(string[EARNINGS]) - int(string[LOSSES])
print(final)
>>>500
Using slice you gain readability.
You can execute it using a function. Example:
var theInstructions = "alert('Hello World'); var x = 100";
var F=new Function (theInstructions);
return(F());
No, you can't undo, rollback or reverse a commit.
(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE
or similar, not an rm -rf /data/directory
scenario).
If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate
so that no checkpoint is run on shutdown.
You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.
If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.
Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base
, pg_clog
, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog
etc. No part is unimportant.
Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.
If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT
or UPDATE
. Thus, the old versions of the UPDATE
d rows might still be lying around, present but inaccessible.
Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter
and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl
in immediate
mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.
Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.
You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.
I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOAST
ed data so it's of limited utility. Give it a try, if you're lucky it might work.
See: pg_dirtyread on GitHub.
I've removed what I'd written in this section as it's obsoleted by that tool.
See also PostgreSQL row storage fundamentals
See my blog entry Preventing PostgreSQL database corruption.
On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED
for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.
I wrote a php function that will do this. I needed to make an insert statement in case a record needs to be replaced after deletion for a history table:

The expression 'AND' and 'OR' and 'NOT'
always evaluates to 'NOT'
, so you are effectively doing
while 'NOT' not in some_list:
print 'No boolean operator'
You can either check separately for all of them
while ('AND' not in some_list and
'OR' not in some_list and
'NOT' not in some_list):
# whatever
or use sets
s = set(["AND", "OR", "NOT"])
while not s.intersection(some_list):
# whatever
Not sure what isn't working in your case, but the following code will put a formula into cell A1 that will retrieve the value in the cell G2.
strProjectName = "Sheet1"
Cells(1, 1).Formula = "=" & strProjectName & "!" & Cells(2, 7).Address
The workbook and worksheet that strProjectName
references must exist at the time that this formula is placed. Excel will immediately try to evaluate the formula. You might be able to stop that from happening by turning off automatic recalculation until the workbook does exist.
Honestly, much as I love sed for appropriate tasks, this is definitely a task for perl -- it's truly more powerful for this kind of one-liners, especially to "write it back to where it comes from" (perl's -i
switch does it for you, and optionally also lets you keep the old version around e.g. with a .bak appended, just use -i.bak
instead).
perl -i.bak -pe 's/\.jpg|\.png|\.gif/.jpg/
rather than intricate work in sed (if even possible there) or awk...
You can also use google-collections (guava) Joiner class if you want to customize the print format
Given that today (was not available when this question was made) lots of people use Jupyter Notebook as python console, there is an extremely easy way to save the plots as .png
, just call the matplotlib
's pylab
class from Jupyter Notebook, plot the figure 'inline' jupyter cells, and then drag that figure/image to a local directory. Don't forget
%matplotlib inline
in the first line!
I have added line
$this->_productCollection->addAttributeToSelect('releasedate');
in
app/code/core/Mage/Catalog/Block/Product/List.php on line 95
in function _getProductCollection()
and then call it in
app/design/frontend/default/hellopress/template/catalog/product/list.phtml
By writing code
<div><?php echo $this->__('Release Date: %s', $this->dateFormat($_product->getReleasedate())) ?>
</div>
Now it is working in Magento 1.4.x
If you have defined a method inside your class as static, this is actually possible.
class myClass
{
public:
static void saySomething()
{
std::cout << "This is a static method!" << std::endl;
}
};
And from main, you declare a pointer and try to invoke the static method.
myClass * pmyClass;
pmyClass->saySomething();
/*
Output:
This is a static method!
*/
This works fine because static methods do not belong to a specific instance of the class and they are not allocated as a part of any instance of the class.
Read more on static methods here: http://en.wikipedia.org/wiki/Static_method#Static_methods
looks like you're better off systeming out to system("grep \"$QUERY\"")
since that script won't be particularly high performance either way. Otherwise http://php.net/manual/en/function.file.php shows you how to loop over lines and you can use http://php.net/manual/en/function.strstr.php for finding matches.
Try this:
public static void main(String[] args) throws IOException {
File file = new File("file.csv");
CSVReader csvFileReader = new CSVReader(new FileReader(file));
List<String[]> list = csvFileReader.readAll();
for (int i = 0; i < list.size(); i++) {
String[] filter = list.get(i);
if (filter[0].equalsIgnoreCase("bbb")) {
list.remove(i);
}
}
csvFileReader.close();
CSVWriter csvOutput = new CSVWriter(new FileWriter(file));
csvOutput.writeAll(list);
csvOutput.flush();
csvOutput.close();
}
If you are converting a varchar to int make sure you do not have decimal places.
For example, if you are converting a varchar field with value (12345.0) to an integer then you get this conversion error. In my case I had all my fields with .0 as ending so I used the following statement to globally fix the problem.
CONVERT(int, replace(FIELD_NAME,'.0',''))
In views with {{}}
and/or ng-model, Angular is setting up $watch()
es for you behind the scenes.
By default $watch
compares by reference. If you set the third parameter to $watch
to true
, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:
$scope.$watch('myModel', function() { ... }, true);
Update: Angular v1.2 added a new method for this, `$watchCollection():
$scope.$watchCollection('myModel', function() { ... });
Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.
Easy and without LINQ:
while (parameterList.Remove(null)) {};
This is what i've implemented:
$(window).resize(function(){ setTimeout(someFunction, 500); });
we can clear the setTimeout if we expect resize to happen less than 500ms
Good Luck...

for React Native 0.49 and over
you should go to project directory on terminal and run that command
1 - mkdir android/app/src/main/assets
2 - react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
if under 0.49
1 - mkdir android/app/src/main/assets
2 - react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
Then Use android studio to open the 'android' folder in you react native app directory, it will ask to upgrade gradle and some other stuff. go to build-> Generate signed APK and follow the instructions from there. That okey.

Here is a post which introduces different types of keystore in Java and the differences among different types of keystore. http://www.pixelstech.net/article/1408345768-Different-types-of-keystore-in-Java----Overview
Below are the descriptions of different keystores from the post:
JKS, Java Key Store. You can find this file at sun.security.provider.JavaKeyStore. This keystore is Java specific, it usually has an extension of jks. This type of keystore can contain private keys and certificates, but it cannot be used to store secret keys. Since it's a Java specific keystore, so it cannot be used in other programming languages.
JCEKS, JCE key store. You can find this file at com.sun.crypto.provider.JceKeyStore. This keystore has an extension of jceks. The entries which can be put in the JCEKS keystore are private keys, secret keys and certificates.
PKCS12, this is a standard keystore type which can be used in Java and other languages. You can find this keystore implementation at sun.security.pkcs12.PKCS12KeyStore. It usually has an extension of p12 or pfx. You can store private keys, secret keys and certificates on this type.
PKCS11, this is a hardware keystore type. It servers an interface for the Java library to connect with hardware keystore devices such as Luna, nCipher. You can find this implementation at sun.security.pkcs11.P11KeyStore. When you load the keystore, you no need to create a specific provider with specific configuration. This keystore can store private keys, secret keys and cetrificates. When loading the keystore, the entries will be retrieved from the keystore and then converted into software entries.

I have a small solution
let data = [{id: 1}, {id: 2}, {id: 3}, {id: 2}, {id: 3}]
let result = data.filter((value, index, self) => self.findIndex((m) => m.id === value.id ) === index))
Both questions are answered in git status
.
To unstage adding a new file use git rm --cached filename.ext
# Changes to be committed:
# (use "git rm --cached <file>..." to unstage)
#
# new file: test
To unstage deleting a file use git reset HEAD filename.ext
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# deleted: test
In the other hand, git checkout --
never unstage, it just discards non-staged changes.
Notice that width:50%
will resize it to 50% of the available space for the image, while max-width:50%
will resize the image to 50% of its natural size. This is very important to take into account when using this rules for mobile web design, so for mobile web design max-width
should always be used.
UPDATE: This was probably an old Firefox bug, that seems to have been fixed by now.
There is a, perhaps subtle, but important misconception in a number these answers. I thought I'd add my answer to clear it up.
What is
HEAD
?
HEAD
is a symbolic reference pointing to wherever you are in your commit history. It follows you wherever you go, whatever you do, like a shadow. If you make a commit, HEAD
will move. If you checkout something, HEAD
will move. Whatever you do, if you have moved somewhere new in your commit history, HEAD
has moved along with you. To address one common misconception: you cannot detach yourself from HEAD
. That is not what a detached HEAD state is. If you ever find yourself thinking: "oh no, i'm in detached HEAD state! I've lost my HEAD!" Remember, it's your HEAD. HEAD is you. You haven't detached from the HEAD, you and your HEAD have detached from something else.
HEAD
can point to a commit, yes, but typically it does not. Let me say that again. Typically HEAD
does not point to a commit. It points to a branch reference. It is attached to that branch, and when you do certain things (e.g., commit
or reset
), the attached branch will move along with HEAD
. You can see what it is pointing to by looking under the hood.
cat .git/HEAD
Normally you'll get something like this:
ref: refs/heads/master
Sometimes you'll get something like this:
a3c485d9688e3c6bc14b06ca1529f0e78edd3f86
That's what happens when HEAD
points directly to a commit. This is called a detached HEAD, because HEAD
is pointing to something other than a branch reference. If you make a commit in this state, master
, no longer being attached to HEAD
, will no longer move along with you. It does not matter where that commit is. You could be on the same commit as your master branch, but if HEAD
is pointing to the commit rather than the branch, it is detached and a new commit will not be associated with a branch reference.
You can look at this graphically if you try the following exercise. From a git repository, run this. You'll get something slightly different, but they key bits will be there. When it is time to checkout the commit directly, just use whatever abbreviated hash you get from the first output (here it is a3c485d
).
git checkout master
git log --pretty=format:"%h: %d" -1
# a3c485d: (HEAD -> master)
git checkout a3c485d -q # (-q is for dramatic effect)
git log --pretty=format:"%h: %d" -1
# a3c485d: (HEAD, master)
OK, so there is a small difference in the output here. Checking out the commit directly (instead of the branch) gives us a comma instead of an arrow. What do you think, are we in a detached HEAD state? HEAD is still referring to a specific revision that is associated with a branch name. We're still on the master branch, aren't we?
Now try:
git status
# HEAD detached at a3c485d
Nope. We're in 'detached HEAD' state.
You can see the same representation of (HEAD -> branch)
vs. (HEAD, branch)
with git log -1
.
HEAD
is you. It points to whatever you checked out, wherever you are. Typically that is not a commit, it is a branch. If HEAD
does point to a commit (or tag), even if it's the same commit (or tag) that a branch also points to, you (and HEAD
) have been detached from that branch. Since you don't have a branch attached to you, the branch won't follow along with you as you make new commits. HEAD
, however, will.
Well, .html()
uses .innerHTML
which is faster than DOM creation.
$eval
and $parse
don't evaluate JavaScript; they evaluate AngularJS expressions. The linked documentation explains the differences between expressions and JavaScript.
Q: What exactly is $eval doing? Why does it need its own mini parsing language?
From the docs:
Expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}. Expressions are processed by $parse service.
It's a JavaScript-like mini-language that limits what you can run (e.g. no control flow statements, excepting the ternary operator) as well as adds some AngularJS goodness (e.g. filters).
Q: Why isn't plain old javascript "eval" being used?
Because it's not actually evaluating JavaScript. As the docs say:
If ... you do want to run arbitrary JavaScript code, you should make it a controller method and call the method. If you want to eval() an angular expression from JavaScript, use the $eval() method.
The docs linked to above have a lot more information.
In order to run natively, you will likely need to use Cygwin (which I cannot live without when using Windows). So right off the bat, +1 for Cygwin. Anything else would be uncivilized.
HOWEVER, that being said, I have recently begun using a combination of utilities to easily PORT Bash scripts to Windows so that my anti-Linux coworkers can easily run complex tasks that are better handled by GNU utilities.
I can usually port a Bash script to Batch in a very short time by opening the original script in one pane and writing a Batch file in the other pane. The tools that I use are as follows:
I prefer UnxUtils to GnuWin32 because of the fact that [someone please correct me if I'm wrong] GnuWin utils normally have to be installed, whereas UnxUtils are standalone binaries that just work out-of-the-box.
However, the CoreUtils do not include some familiar *NIX utilities such as cURL, which is also available for Windows (curl.haxx.se/download.html).
I create a folder for the projects, and always SET PATH=. in the .bat file so that no other commands other than the basic CMD shell commands are referenced (as well as the particular UnxUtils required in the project folder for the Batch script to function as expected).
Then I copy the needed CoreUtils .exe files into the project folder and reference them in the .bat file such as ".\curl.exe -s google.com", etc.
The Bat2Exe program is where the magic happens. Once your Batch file is complete and has been tested successfully, launch Bat2Exe.exe, and specify the path to the project folder. Bat2Exe will then create a Windows binary containing all of the files in that specific folder, and will use the first .bat that it comes across to use as the main executable. You can even include a .ico file to use as the icon for the final .exe file that is generated.
I have tried a few of these type of programs, and many of the generated binaries get flagged as malware, but the Bat2Exe version that I referenced works perfectly and the generated .exe files scan completely clean.
The resulting executable can be run interactively by double-clicking, or run from the command line with parameters, etc., just like a regular Batch file, except you will be able to utilize the functionality of many of the tools that you will normally use in Bash.
I realize this is getting quite long, but if I may digress a bit, I have also written a Batch script that I call PortaBashy that my coworkers can launch from a network share that contains a portable Cygwin installation. It then sets the %PATH% variable to the normal *NIX format (/usr/bin:/usr/sbin:/bin:/sbin), etc. and can either launch into the Bash shell itself or launch the more-powerful and pretty MinTTY terminal emulator.
There are always numerous ways to accomplish what you are trying to set out to do; it's just a matter of combining the right tools for the job, and many times it boils down to personal preference.
I've generalized this into a Jquery plugin which takes a regex as an argument.
Coffee:
$.fn.removeClassRegex = (regex) ->
$(@).removeClass (index, classes) ->
classes.split(/\s+/).filter (c) ->
regex.test c
.join ' '
Javascript:
$.fn.removeClassRegex = function(regex) {
return $(this).removeClass(function(index, classes) {
return classes.split(/\s+/).filter(function(c) {
return regex.test(c);
}).join(' ');
});
};
So, for this case, usage would be (both Coffee and Javascript):
$('#hello').removeClassRegex(/^color-/)
Note that I'm using the Array.filter
function which doesn't exist in IE<9. You could use Underscore's filter function instead or Google for a polyfill like this WTFPL one.
