my live site is https site.
My test site urls are working fine with
$url = route('admin.taskmanager.taskmanager.edit', [$task->id]);
which is generating
http://example.com/app/taskmanager/taskmanagers/89/edit
but the same url in live site is generating
https://example.com/app/taskmanager/taskmanagers/89/edit
PROBLEM:
Above live site url is generating 502 gateway error.
but when I add /en to the url like
https://example.com/en/app/taskmanager/taskmanagers/89/edit
it is working.
Both are nginx platform with same conf files.
Test site which is http site is automatically adding /en
but live site with https is not adding /en to my generated urls using routes are throwing 502 error.
Any help?
@matiaslauriti my router is as below
$router->group(['prefix' => '/taskmanager'], function(Router $router) {
$router->bind('taskmanager', function($id) {
return app('Modules\Taskmanager\Repositories\TaskmanagerRepository')->find($id);
});
$router->get('taskmanagers/{taskmanager}/edit', [
'as' => 'admin.taskmanager.taskmanager.edit',
'uses' => 'TaskmanagerController@edit',
'middleware' => 'can:taskmanager.taskmanagers.access'
]);

I would like to obtain:

i.e. I would like to keep those rows whose numbers in columns B and C only match, for example YRI_1 / Medit_1 both have a "1" so it is a wanted row, but I would not like to keep for example YRI_1 / Medit_10, since this is "10" although it contains a "1".
I tried with awk:
for i in {1..4}
do
awk '$2=="*$i"||$3=="*$i" {print $1,$2,$3,$4,$5}' table > desired_table
done
where $i was supposed to be substituted in each iteration by the next number in the list 1..4, and also I pretended * to mean anything, because I am interested in the number (but I guess this is not the way to do it with awk).
A: You can use this awk command:
awk 'split($2, a, /_/) && split($3, b, /_/) && a[2] == b[2]' file
A B C D E

9 YRI_2 CHB_2 10668 0
*
*We use 2 split functions to split $2 and $3 and then compare 2nd fields of split array for equality.
*split returns number of elements in the resulting array. By using awk 'split($2, a, /_/) && split($3, b, /_/) && we are making sure that split is returning non-zero values.
A: Remove all chars except numbers ([^0-9]) from related cols and print if they match.

Currently I'm calling the cuda kernels within a C++ static function wrapper, so I can call the kernels from a .cpp file (not .cu), like this:
//kernels.cu:
//kernel definition
__global__ void kernelCall_kernel( dataRow* in, dataRow* out, void* additionalData){
//Do something
};
//kernel handler, so I can compile this .cu and link it with the main project and call it within a .cpp file
extern "C" void kernelCall( dataRow* in, dataRow* out, void* additionalData){
int blocksize = 256;
dim3 dimBlock(blocksize);
dim3 dimGrid(ceil(tableSize/(float)blocksize));
kernelCall_kernel<<<dimGrid,dimBlock>>>(in, out, additionalData);
}
If I call the handler as a normal function, the data printed is right.
//streamProcessing.cpp
//allocations and definitions of data omitted
//copy data to GPU
cudaMemcpy(data_d,data_h,tableSize,cudaMemcpyHostToDevice);
//call:
kernelCall(data_d,result_d,null);
//copy data back
cudaMemcpy(result_h,result_d,resultSize,cudaMemcpyDeviceToHost);
//show result:
printTable(result_h,resultSize);// this just iterate and shows the data
But to allow parallel copy and execution of data on the GPU I need to create a thread, so when I call it making a new boost::thread:
//allocations, definitions of data,copy data to GPU omitted
//call:
boost::thread* kernelThreadOwner = new boost::thread(kernelCall, data_d,result_d,null);
kernelThreadOwner->join();
//Copy data back and print ommited
I just get garbage when printing the result on the end.
Currently I'm just using one thread, for testing purpose, so there should be no much difference in calling it directly or creating a thread. I have no clue why calling the function directly gives the right result, and when creating a thread not. Is this a problem with CUDA & boost? Am I missing something? Thank you in advise.
A: The problem is that (pre CUDA 4.0) CUDA contexts are tied to the thread in which they were created. When you are using two threads, you have two contexts. The context that the main thread is allocating and reading from, and the context that the thread which runs the kernel inside are not the same. Memory allocations are not portable between contexts. They are effectively separate memory spaces inside the same GPU.
If you want to use threads in this way, you either need to refactor things so that one thread only "talks" to the GPU, and communicates with the parent via CPU memory, or use the CUDA context migration API, which allows a context to be moved from one thread to another (via cuCtxPushCurrent and cuCtxPopCurrent). Be aware that context migration isn't free, and there is latency involved, so if you plan to migrating contexts around frequently, you might find it more efficient to change to a different design which preserves context-thread affinity.

cat config.json | grep -Po '"server"\s*:\s*"([^"]*)"'
But I just want the part within (parentheses). I can't use a look-behind because it's variable-length. What are my options?
Sample input 1:
{"debug":false,"server":"dev-dutch","env":"dev"}
Sample input 2:
{
"debug": false,
"server": "dev-dutch",
"env": "dev"
}
Desired output for both:
dev-dutch
I know there are probably safer/better ways to parse JSON, but I want to do this in shell, and it should run on both Ubuntu and FreeBSD without installing any external programs, so I'm OK with a grep hack.
A: With GNU grep:
grep -Po '"server": *"\K[^"]+' file

(1) What's the sequence of firmware/software get called from x86 system bootstrap?
x86 power on reset-->coreboot-->SeaBIOS->GRUB->Linux kernel?
(2) If we use mini-sata as non-volatile storage, how should the grub binary and configuration file be stored on mSATA, in the MBR or something?
(3) How should linux kernel initrd be stored, in filesystem or on a raw disk? I recall from PowerPC development that there are no constraint on where kernel and ramdisk stored in flash, u-boot just need the address to bring kernel up.
A: It depends.
Your proposed flow with seabios and grub is certainly possible, but grub2 can act as a coreboot payload, too - in that case it's coreboot->grub->Linux.
Or if you don't estimate changing the kernel all the time, or if you go for kexec(), you can do coreboot->Linux, with Linux in flash.
Assuming you're going for a boot flow involving grub2, let's look at the other questions: With seabios, grub2 would be stored in MBR and some spare sectors, like with PCBIOS. With grub2 as payload, it's stored in flash.
No matter where grub2 resides, its configuration file, Linux kernel and initrd are best stored in a filesystem. grub2 provides drivers for nearly every modern filesystem, and it's the easiest way to maintain them from within the OS.

Per my understanding, I can't refer a .NET Standard library in a .NET Framework Library. I searched all over the internet but I couldn't find any way other than migrating my whole service to .NET Core.NET Standard.
Is there any other way to upgrade the latest version of Azure Storage SDKs?
A:
Is there any other way to upgrade the latest version of Azure Storage SDKs?
Direct upgrade from version 6 to 12 is not possible as SDK version 12 is actually quite different than older versions (9 or below).
Firstly, now the SDK is split in many SDKs and there are different SDKs for each service (Blobs, Files and Queues). Thus you would need to reference different Nuget packages in your source code.
Secondly, there have been many breaking changes in the SDKs thus simply referencing the Nuget packages for version 12 is just not sufficient. You will need to rewrite the code unfortunately.

I am having trouble coding the last row and column boxes. Basically, if say for Row 1, there is even a single 'Red', the last box on row 1 (1,6) should automatically turn red. If there is no red, but there is an 'amber', the last box should turn 'amber'. If there is a 'red' and an 'amber', 'red' should be given the priority. Similar logic for columns as well.
What I have tried so far:
Within the userform code:
Private Sub Txt_Score_1_1_Change() 'This is for row 1 column 1 on the matrix'
Call ScoreChange.ScoreChange("Txt_Score_1_1")
Within a module:
Public Sub ScoreChange(ctrlName As String)
If Scorecard.Controls(ctrlName).Value = "R" Then
Scorecard.Controls(ctrlName).BackColor = vbRed
ElseIf Scorecard.Controls(ctrlName).Value = "G" Then
Scorecard.Controls(ctrlName).BackColor = vbGreen
ElseIf Scorecard.Controls(ctrlName).Value = "A" Then
Scorecard.Controls(ctrlName).BackColor = vbYellow
Else
Scorecard.Controls(ctrlName).BackColor = vbWhite
End If
For i = 1 To 5
For j = 1 To 5
If Scorecard.Controls("Txt_Score_" & i & "_" & j).Value <> "" Then
If Scorecard.Controls("Txt_Score_" & i & "_" & j).Value = "R" Then
Scorecard.Controls("Txt_Score_" & i & "_6").Value = "R"
Scorecard.Controls("Txt_Score_6_" & j).Value = "R"
ElseIf Scorecard.Controls("Txt_Score_" & i & "_" & j).Value = "A" Then
Scorecard.Controls("Txt_Score_" & i & "_6").Value = "A"
Scorecard.Controls("Txt_Score_6_" & j).Value = "A"
End If
End If
Next j
Next i
End Sub
The above works to change the individual colours of the combo boxes when changed but falls apart for the 'total'/'all up' boxes.
What I think needs to be done to achieve the above is that I need to write a code that recognises when all the combo boxes for a specific row/column have been filled, and then stores those values in an array, and recognises within the array, the value for the last box.
Any help on how to achieve this will be appreciated.
Also, apologies if something similar has been posted elsewhere, but I did a lot of research and couldn't find anything.
Thanks.
A: I think there might be a simpler way of attacking this task, and certainly an easier way of consuming all the ComboBox_Change events.
If I understand your question correctly, you are saying that you have a matrix of 5 by 5 'child' ComboBoxes. You then have 5 'parent' controls that change based on the selection of the rows' children, and 5 'parent controls' that do the same for the columns' children.
What you could do, therefore, is create two classes. I've called them clsChild and clsParent. The child class traps the change event and then notifies the row and column parents that a change has occured. The parent class contains a list of its children and runs the colouring rules based on the children's selection.
In terms of the rules, I've created an Enum of your colours where Red is lowest and White is the highest, so you simply take the lowest 'score' of any of the children to colour the parent control.
I've kept the same naming conventions as your post for the ComboBoxes but I don't see why the 'parent' controls are Comboboxes - surely you wouldn't want a user to be able to change them? I've taken the liberty then of making them Labels with the naming convention Lbl_Score_R1 ... R5 for rows and Lbl_Score_C1 ... C5 for columns.
The beauty of this method is that you only need to tie up the relationships between children and parents once and simply pass the control objects between them. This will avoid having to do your awkward string manipulation every time a change event occurs.
So, the code...
i. Insert a new class and call it clsChild. Add the following code:
Option Explicit
Private WithEvents mCtrl As MSForms.ComboBox
Private mMum As clsParent
Private mDad As clsParent
Private mLight As Lights
Public Property Set Mum(val As clsParent)
Set mMum = val
Set mMum.ChildInLine = Me
End Property
Public Property Set Dad(val As clsParent)
Set mDad = val
Set mDad.ChildInLine = Me
End Property
Public Property Set Ctrl(val As MSForms.ComboBox)
Set mCtrl = val
With mCtrl
.List = Array("R", "A", "G", "W")
.ListIndex = 3
End With
End Property
Public Property Get Light() As Lights
Light = mLight
End Property
Private Property Let Light(val As Lights)
mLight = val
With mCtrl
Select Case mLight
Case Lights.Red: .BackColor = vbRed
Case Lights.Amber: .BackColor = vbYellow
Case Lights.Green: .BackColor = vbGreen
Case Lights.White: .BackColor = vbWhite
End Select
End With
If Not mMum Is Nothing Then mMum.ConsumeChildChanged
If Not mDad Is Nothing Then mDad.ConsumeChildChanged
End Property
Private Sub mCtrl_Change()
Select Case mCtrl.Value
Case Is = "R": Light = Red
Case Is = "A": Light = Amber
Case Is = "G": Light = Green
Case Else: Light = White
End Select
End Sub
ii. Insert another new class and call it clsParent and add the following code:
Option Explicit
Private mCtrl As MSForms.Label
Private mChildren As Collection
Private mLight As Lights
Public Property Set Ctrl(val As MSForms.Label)
Set mCtrl = val
Set mChildren = New Collection
End Property
Public Property Set ChildInLine(val As clsChild)
mChildren.Add val
End Property
Public Sub ConsumeChildChanged()
Dim lowest As Lights
Dim oChild As clsChild
lowest = White
For Each oChild In mChildren
With oChild
If .Light < lowest Then
lowest = .Light
End If
End With
Next
Light = lowest
End Sub
Private Property Get Light() As Lights
Light = mLight
End Property
Private Property Let Light(val As Lights)
mLight = val
With mCtrl
Select Case mLight
Case Lights.Red: .BackColor = vbRed
Case Lights.Amber: .BackColor = vbYellow
Case Lights.Green: .BackColor = vbGreen
Case Else: .BackColor = vbWhite
End Select
End With
End Property
iii. At the top of any Module add the following:
Public Enum Lights
Red
Amber
Green
White
End Enum
iv. And finally add the following to your UserForm code:
Option Explicit
Private mMum(1 To 5) As clsParent
Private mDad(1 To 5) As clsParent
Private mChild(1 To 5, 1 To 5) As clsChild
Private Sub UserForm_Initialize()
Dim i As Integer, j As Integer
For i = 1 To 5
Set mMum(i) = New clsParent
Set mMum(i).Ctrl = Me.Controls("Lbl_Score_R" & i)
Set mDad(i) = New clsParent
Set mDad(i).Ctrl = Me.Controls("Lbl_Score_C" & i)
Next
For i = 1 To 5
For j = 1 To 5
Set mChild(i, j) = New clsChild
With mChild(i, j)
Set .Ctrl = Me.Controls("Txt_Score_" & i & "_" & j)
Set .Mum = mMum(i)
Set .Dad = mDad(j)
End With
Next
Next
End Sub

Now when I try and make use of these factories using the following
Session session = getHibernateTemplate().getSessionFactory().openSession();
I always get the first factory by default and am able to access all the tables in its schema but not the second one. How do I specify which factory I want to use?
A: The HibernateTemplate constructor takes a SessionFactory as argument. I don't know what getHibernateTemplate() does in your code, but it should return a HibernateTemplate built with one of the SessionFactory beans you defined (either by declaring them in the spring context xml file, or by constructing them in Java from one of the injected session factories).
Note that, as the documentation of HibernateTemplate says (in bold):
As of Hibernate 3.0.1, transactional
Hibernate access code can also be
coded in plain Hibernate style. Hence,
for newly started projects, consider
adopting the standard Hibernate3 style
of coding data access objects instead,
based on
SessionFactory.getCurrentSession().
I would inject the session factory directly, and use the Hibernate API directly. HibernateTemplate doesn't bring much over the Hibernate API and often gets in the way, IMHO. (For example by not providing an equivalent to Query.uniqueResult()).

This wouldn't normally be an issue but recently I noticed that the class list is unreadable because the long class names make it too wide to fit on a screen.
Is there a way to make Doxygen break names of classes in the class list to more lines? Is there perhaps a way to hide specializations of a template class from class list while retaining the general template class? Is there a better solution?
I managed to find a silly work-around by hiding the classes in a namespace and then immediately importing this namespace to the global namespace, so that the names of those classes would not appear on the list, unless the namespace is clicked or detail level is increased. The obvious downside is that the classes now do not appear on the list (some of those are fairly important and I'd like them to be there).
I could also remove the following style:
.directory td.entry {
white-space: nowrap;
}
This can be done by saving this:
.directory td.entry {
white-space: normal;
}
as modify.css and specifying it under HTML_EXTRA_STYLESHEET. There are more word wrap tags however (e.g. flex-wrap), so additional editing might be required.
A: Finally, I went with modifying the css. I ended up using:
.directory td.entry {
white-space: normal;
/*width: 50%;*/ /* does not work, makes "Related Pages" look bad */
min-width: 512px; /* better, unless you have a 640x480 screen */
}
I saved this as doxygen_modify.css and specified path to it in HTML_EXTRA_STYLESHEET (note that if named doxygen.css, it will not be renamed automatically and instead it will be replaced by the main style sheet - and hence you will not see any changes).

Originally I installed Linux 17.2 (and later updated to 17.3) to do the job, however there seemed to be some conflict with my box causing there to be intermittent booting problems (it would often just stop dead and the monitor would go into power save, this didn't happen all the time but enough to be a problem)...
So I decided to update to Linux 18 to see if the problem persisted, which I;m happy to say, it does not, no boot problems at all, however I've instead run into a new problem :(
Since Linux Mint 8 has PHP7 by default in its repositories it is not compatible with what I'm trying to run, so I've been attempting to get PHP 5.6 installed, which I believe I have done, at-least it tells me I have it installed when I check the version in the terminal.
php -v

PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend
Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by

I achieved this with the following:
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:ondrej/php
$ sudo apt-get update
$ sudo apt-get install -y php5.6 php5.6-mcrypt php5.6-gd
http://tecadmin.net/install-laravel-framework-on-ubuntu/
However, following the same walk-through, I am unable to install as described because I get the following error:
Package libapache2-mod-php5 is not available, but is referred to by
another package. This may mean that the package is missing, has been
obsoleted, or is only available from another source
E: Package 'libapache2-mod-php5' has no installation candidate
and yet when I try installed apache2 flat
$ sudo apt-get install apache2
While apache works, PHP fails to work at all, I created a page with the phpinfo(); method and I simply get a blank page :(
Can somebody please help me shed some light on this ?
Thanks for any help in advance :(
Regards,
A: Try this module instead:
sudo a2enmod php5.6
sudo service apache2 restart

How can I access or directly make a list from all foo::bar values from hieradata file (below) in the Puppet module with lookup() or better way?
---
foo::bar:
'some uniq name':
baz: 12345
...
'another uniq name':
baz: 54321
...
So if it would be possible to use wildcards the key path would look like this -> foo::bar::*::baz.
A: This requires the use of the lookup function, a lambda iterator, and hash syntax notation, so it actually is not that easy, although the code may make it seem that way.
We need to iterate over the values for the keys inside the foo::bar hash. We can start off with that via:
lookup(foo::bar, Hash).each |String $key, Hash $value| {
# first $key is 'some uniq name' string
# first $value is 'some uniq name' hash
}
Now we need to access the values for the bar key inside each nested hash. We can do that by the normal syntax for accessing values of keys inside a hash:
lookup(foo::bar, Hash).each |String $key, Hash $value| {
$value['baz'] # first value is 12345
}
However, we need to store these values inside a variable so they are retained instead of being discarded after exiting the lambda scope. Therefore, we need to have a variable store the return value of the lambda iterator and use a lambda iterator that returns a modified array:
$bazes = lookup(foo::bar, Hash).map |String $key, Hash $value| {
$value['baz']
}
Thus achieving the goal of storing an array (or list as you put it) of all the baz values inside the hieradata. Although the code is short, it is arguably not that simple.

Functions are not valid as a React child
A: From AbTest component, you must return the component instance like
const AbTest = ({ components, criteriaToMatch }) => {
let ComponentToRender;
components.forEach((component) => {
if (component.criteria === criteriaToMatch) {
ComponentToRender = component.instance;
}
});
return <ComponentToRender />;
};

my cart activity
public class CartActivity extends AppCompatActivity {
Button l;
ImageView imv;
Toolbar t;
RecyclerView rv;
RecyclerView.LayoutManager layoutmanager;
RecyclerView.Adapter adapter;
List<products> cartitems;
ArrayList<products> selected_items_list = new ArrayList<>();
SharedPreference sharedPreference;
public static final String MyPREFERENCES = "MyPrefs";
int countt = 0;
boolean edit_mode = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cart);
rv = (RecyclerView) findViewById(R.id.mycartrecycler);
layoutmanager = new LinearLayoutManager(this);
rv.setLayoutManager(layoutmanager);
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
String jsonFavorites = preferences.getString(FAVORITES, null);
Gson gson = new Gson();
products[] favoriteItems = gson.fromJson(jsonFavorites,
products[].class);
cartitems = Arrays.asList(favoriteItems);
cartitems = new ArrayList<products>(cartitems);
adapter = new CartAdapter(cartitems, CartActivity.this);
rv.setAdapter(adapter);
}
}
A: Because you add the whole list in sharedpreferences.. look at below
you did this...
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(mContext);
SharedPreferences.Editor editor = preferences.edit();
Gson gson = new Gson();
String jsonFavorites = gson.toJson(productList);
1) if you want the specific selected result then you have to make a pojo class of product with the contain details like
public TextView title, count;
public ImageView thumbnail, cart;
private Context context;
and make getter and setter method of all fields.
in onclick method of cart,you have to pass that pojo class and get that class in your cart activity. that's how you can get your desire output.
2) the second way to add all details as a field of sharedpreferences like
editor.putString("title",title.getText().toString());
and set all count and thumbnail as an value.
I hope it will help you...
A: You are saving productList in SharedPreference.
Try like this
final Product product = productList.get(position);
// Some other code
holder.cart.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
holder.cart.setImageResource(R.drawable.ic_add_cart);
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(mContext);
SharedPreferences.Editor editor = preferences.edit();
Gson gson = new Gson();
String jsonFavorites = gson.toJson(product);
editor.putString(FAVORITES, jsonFavorites);
editor.commit();
}
});
In CartActivity
Gson gson = new Gson();
Product product = gson.fromJson(jsonFavorites,
Product.class);

android.os.Process.killProcess(android.os.Process.myPid());
System.exit(1);
System.exit(0);
All works, but the operating system shows me a message saying that the application has stopped and there is a button that says "restart application"
Is there a way to avoid that?
A: Did you tried ?
this.finishAffinity();
or
finishAndRemoveTask ();
Use System.exit(0); is a bad solution to finish an App.

if(count >= SIZE)
{
Ship *hold = new Ship[SIZE]; // to hold for a while value of list
for(int q = 0; q < SIZE; q++)
hold[q] = list[q];
delete[] list; //delete list
Ship *list = new Ship[SIZE + 10]; //set a new size for list
for(int q = 0; q < SIZE - 10; q++)
list[q] = hold[q];
delete[] hold;
}
A: There is no need for hold, just copy the old list to the new one.
But the real mistakes in your code are that you don't change SIZE but you assume that it has changed
Ship *list = new Ship[SIZE + 10]; //set a new size for list
for(int q = 0; q < SIZE - 10; q++)
should be
Ship *list = new Ship[SIZE + 10]; //set a new size for list
for(int q = 0; q < SIZE; q++)
...
SIZE += 10;
and that you declare a new list variable, when you should be changing the existing list variable.
Ship *list = new Ship[SIZE + 10]; //set a new size for list
should be
list = new Ship[SIZE + 10]; //set a new size for list
Here's your code with all mistakes fixed
if(count >= SIZE)
{
Ship *new_list = new Ship[SIZE + 10]; //make the new list
for(int q = 0; q < SIZE; q++) //copy from the old list
new_list[q] = list[q];
delete[] list; //delete the old list
list = new_list; //use the new list
SIZE += 10; //set a new size for list
}
Now here's the same code using std::vector
vec.resize(vec.size() + 10);
std::vector is a little bit easier (actually it's a whole lot easier). You should use it.
A: be careful when working with pointers.
// -------------- include directives:
#include <iostream>
#include <string>
// -------------- your class definitions
class ship {
public:
ship() {}
virtual ~ship() {}
};
// ------- declaration state
#define ADDITIONAL_RESERVED_SLOTS (10)
unsigned int arraySize{3};
unsigned int shipCount{}; // initial with zero count
ship* shipArray{nullptr}; // its very important to fill pointers with null for initialialization
void addNewShip(const ship& new_ship); // function prototype
put these lines in your initializer block of code
// ------- allocate array dynamicly with 3 slot
ship* shipArray = new ship[arraySize];
// zero allocated memory for pervent from mistakes
std::memset(shipArray, 0, (sizeof(ship) * arraySize));
add new ship in to your array with define a generic function like this:
void addNewShip(const ship& new_ship) {
if(++shipCount > arraySize) {
arraySize += ADDITIONAL_RESERVED_SLOTS;
// allocate new array
ship* pNewShipArray = new ship[arraySize];
// zero allocated memory for pervent from mistakes
std::memset(pNewShipArray, 0, (sizeof(ship) * arraySize));
// copy previuse data in to the new array
std::memcpy(pNewShipArray, shipArray, (sizeof(ship) * (shipCount - 1)));
// delete previuse array
delete[] shipArray;
// now you can use shipArray
shipArray = pNewShipArray;
}
// add new ship in to your array
shipArray[shipCount - 1] = new_ship; // be carefull!! if you have pointers in your ship class you most handle them too.

logs/foo/per_process_dir/journal.log
My little daemon is written in Python and uses the watchdog-module to watch over the files (inotify is used by the module on Linux). I simply ask the module to monitor the foo/ subdirectory (recursively) and it notifies me, whenever a journal is appended...
This all works but... The whole logs/ directory is rotated, when the application is restarted -- and I'd like my daemon to notice this automatically so that there'd be no need to restart it too.
I expected to receive a "moved" event -- when logs/ is renamed to logs-Sunday/, for example -- but it does not happen... The daemon is small currently and I loath having to enlarge it by adding the code for watching the logs/ folder separately.
Is there some other way, perhaps?
A: If you want to catch renames of the logs directory, you will need to attach your observer to its parent directory. That is, if your logs directory is actually appname/logs, then instead of calling, e.g.:
observer.schedule(event_handler, 'appname/logs', recursive=True)
You would use:
observer.schedule(event_handler, 'appname', recursive=True)
(And you will subsequently need to filter events and ignore those that are outside of the logs directory.)
This happens because your filesystem observer is attached to the logs directory. When you rename the logs directory, your observer continues to monitor it...under the new name. That is, the observer is attached to the inode, not to the path.

Now Media Library shows only list view (grid view is hanging with loader rolling) and when I upload images in Media Library it says "//Kuvaesitys" under "Maximum upload file size: 64MB" and in blue bar it says "Crunching...".
When uploading image in Customize view it gives this error message: "An error occurred in the upload. Please try again later."
My wild guess is there's something in the php above that is doing this but I can't find out what.

IIS 7.0, IIS 7.5, and IIS 8.0 define several HTTP status codes that
indicate a more specific cause of a 401 error. The following specific
HTTP status codes are displayed in the client browser but are not
displayed in the IIS log:
*
*401.1 - Logon failed.
*401.2 - Logon failed due to server configuration.
*401.3 - Unauthorized due to ACL on resource.
*401.4 - Authorization failed by filter.
*401.5 - Authorization failed by ISAPI/CGI application.
I need some custom extended HTTP codes like these:
*
*401.10 - User not found
*401.11 - User password mismatch
*401.12 - User account is locked
*401.13 - User account is expired
*...
How to return these extended 401 error codes from .NET MVC application?
A:
How to return these extended 401 error codes from .NET MVC application?
You cannot return them from your application in the sense that the user will receive them, as HTTP does not support substatus codes.
They are used only for IIS logging and tracing, only the "major" status code is returned.
A: Use Response.StatusCode and Response.SubStatusCode
A: In your action method you set the status codes manually:
Response.StatusCode = 401;
Response.SubStatusCode = 10;
Additionally, you can use the HttpStatusCode enumeration in System.Net:
Response.StatusCode = (int)HttpStatusCode.Unauthorized;

.bash_profile (line 2): if [ -f "$(brew --prefix)/opt/bash-git- prompt/share/gitprompt.sh" ]; then

is generated by the fish shell.
The .bash_profile file is intended only to be executed (sourced) by the bash shell. fish is a different shell, with different syntax; it's not compatible with bash.
If you're using fish as your interactive shell, and you want some commands to be executed automatically when you start a new shell, you'll need to translate the bash-specific commands to fish syntax and add them to your fish startup file. (Not a lot of people use fish, so providers of software packages aren't likely to provide startup commands in fish syntax -- but this package apparently does; see chepner's answer.)
A: Although the linked repository contains a script for fish, the README does not provide any directions for how to use that script. Not having used fish in several years, I think what you want to do is add
if status --is-login
source (brew --prefix)"/opt/bash-git-prompt/share/gitprompt.fish"
end
to ~/.config/fish/config.fish instead. The if status command prevents the file from being unnecessarily sourced if you aren't starting an interactive shell.

Simplified I have the following situation: one table rates with columns rate and converted generated with the scaffold statement within ruby. The column rate will be shown in the view, but the converted column not which will only be used in the background of the application.
Now it's my goal to ask the user for a rate given in the field rate so the application can calculate the converted and store this value in the database. It's a simple calculation: converted = 1 / rate.
Please advice :).
A: Well there are a ton of ways to do that, including but not limited to putting the logic in the model (probably cleanest), in the controller and in the view itself with a hidden field and javascript.
I would do it at the model level with a callback. For example, add this to your rates.rb model:
before_save :calculate_converted_rate
private
def calculate_converted_rate
self.converted = 1.0 / self.rate
end
Which as the code might suggest sets the converted field to the inverse of the rate field each time before a Rates instance is saved.
More information on ActiveRecord callbacks: http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html
A: Define your own mutator method in your model. This will allow you to take the input from your user, do what you want with it, then store it in the database. To illustrate:
class Rate < ActiveRecord::Base
def rate=(value)
write_attribute :rate, value
write_attribute :converted, 1.0 / value
end
end
This will override Rails' default rate= method, which is what gets called when your model is passed your rate data from (assumedly) your form. Construct your model's form normally, with a <%= f.text_field :rate %> or whatever you need to do.
Note the 1.0 / value, not 1 / value - this will ensure the result of that expression is a float, and that you won't lose any precision. If you divide an integer by an integer in Ruby, you'll always get an integer.

On the Execution of the Job Start Windows Batch file it will invoke the dimtableinsert job and then after it finishes it will invoke fact_dim_combine it is taking just minutes to run in the Talend Open Studio but when I invoke the batch file via the Task Scheduler it is taking hours for the process to finish
Time Taken
Manual -- 5 Minutes
Automation -- 4 hours (on invoking Windows batch file)
Can someone please tell me what is wrong with this Automation Process
A: The easiest way to know what is taking so much time is to add some logs to your job.
First, add some tWarn at the start and finish of each of the subjobs (dimtableinsert and fact_dim_combine) to know which one is the longest.
Then add more logs before/after the components inside the jobs.
This way you should have a better idea of what is responsible for the slowdown (DB access, writing of some files, etc ...)
A: The reason of the delay in the execution would be a latency issue. Talend might be installed in the same server where database instance is installed. And so whenever you execute the job in Talend, it will complete as expected. But the scheduler might be installed in the other server, when you call the job through scheduler, it would take some time to insert the data.
*
*Make sure you scheduler and database instance is on the same server
*Execute the job directly in the windows terminal and check if you have same issue

success: function(html) {

}
});
});
To load more items into a container which is sorted with jquery masonry. However when they are appended they do not follow the rest of the items and break the masonry style.
The new items work as a masonry layout, but they just dont continue on from the first ones. They start there own line.
I have searched and found this information on their site:
msnry.appended( elements )
// or with jQuery
$container.masonry( 'appended', elements )
I just need help modifying my original script to make the appended items work with masonry.
thanks, craig.
A: What you can do is append your incoming html to the masonry container and then 'inform' masonry about it. Take a look at this fiddle. So in your example, your success callback could look something like:
//...
success: function(html) {
var content = $("#content"),
elements = $(html);
// would make sense to reference your masonry container through
// a variable used earlier in the script, but that should work too
content.append(html).masonry('appended', elements);
}
//...
There are some other ways to do this, but it should suffice for what you described. What's important is that you pass elements that are of 'Type: Element, NodeList, or Array of Elements', so you might want to check what you're actually receiving.

queue = cl.CommandQueue(ctx,properties=cl.command_queue_properties.PROFILING_ENABLE)
<other codes>
for i in range(N):
events.append(prg3.butterfly(queue,(len(twid),),None,twid_dev,<buffers>))
events[i].wait()
for i in range(N):
elapsed = elapsed + 1e-9*(event[i].profile.end - event[i].profile.start)
print elapsed
While time module can be used like this,
k=time.time()
for i in range(N):
event = prg3.butterfly(queue,(len(twid),),None,twid_dev,<buffers>)
print time.time()-k
Since both of these give totally different results for N=20, ( while answer remains same and correct!), I have the following questions.
*
*What exactly does event profiling do and is it adding the time spent in event.wait() ?
*Since answer is same without event.wait() in case 2, is it the right amount of time spent in just executing the Kernel?
Please enlighten me about the right way to benchmark OpenCL programs in python.
A: Your second case is only capturing the time taken to enqueue the kernel, not to actually run it. These enqueue kernel calls return as soon as the kernel invocation has been placed in the queue - the kernel will be run asynchronously with your host code. To time the kernel execution as well, just add a call to wait until all enqueued commands have finished:
k=time.time()
for i in range(N):
event = prg3.butterfly(queue,(len(twid),),None,twid_dev,<buffers>)
queue.finish()
print time.time()-k
Your first case is correctly timing the time spent inside kernel execution, but is unnecessarily blocking the host in-between each kernel invocation. You could just use queue.finish() again once all commands have been enqueued:
for i in range(N):
events.append(prg3.butterfly(queue,(len(twid),),None,twid_dev,<buffers>))
queue.finish()
for i in range(N):
elapsed = elapsed + 1e-9*(event[i].profile.end - event[i].profile.start)
print elapsed
Both of these approaches should return almost identical times.

So far, it goes as follows:

import json
import re
url = 'www.html_code_url'
page = requests.get(url)
soup = BeautifulSoup(page.content, 'html.parser')
for script in soup.findAll('script'):
if 'required_json_content'in script.get_text():
json = script.get_text.replace('unnecessary_stuff','')
I also replace other tags that come along when I extract the JSON.
However, there is a portion of the text which I can't really remove. It goes something like this, right after the JSON:
something.push({"key1" : "field1","dict1" : [{"Id": 12479895,"randomnumber" : 1325757 ,"WebTree":{"options":[]}}]})
Is there a way to remove this 100 percent of the time?

I have tried to get this problem solved for several hours now and my head is aching (especially because I did already solve it earlier but can't remember how, the script in which I use my solution is stored on a caomputer at school).
Ok so this is my problem. In a given sequence of A's, T's, G's and C's (yup that's DNA) I have to find all the amino acids and count how many there are of them. In layman terms it comes down to this.
I have to search the sequence for certain patterns (also called codons) these are three letter long sequences of A's and/or T's and/or G's and/or C's. Each amino acid has at least one codon associated with it. My job is to count the amount of occurences of each amino acid.
In the second table you'll see the amino acid's to the left and the associated codons to the right.
I have a dictionary set up like so:
aaDic = {'ttt': 'F', 'tct': 'S', 'tat': 'Y', 'tgt': 'C',
'ttc': 'F', 'tcc': 'S', 'tac': 'Y', 'tgc': 'C',
'tta': 'L', 'tca': 'S', 'taa': '*', 'tga': '*',
'ttg': 'L', 'tcg': 'S', 'tag': '*', 'tgg': 'W',
'ctt': 'L', 'cct': 'P', 'cat': 'H', 'cgt': 'R',
'ctc': 'L', 'ccc': 'P', 'cac': 'H', 'cgc': 'R',
'cta': 'L', 'cca': 'P', 'caa': 'Q', 'cga': 'R',
'ctg': 'L', 'ccg': 'P', 'cag': 'Q', 'cgg': 'R',
'att': 'I', 'act': 'T', 'aat': 'N', 'agt': 'S',
'atc': 'I', 'acc': 'T', 'aac': 'N', 'agc': 'S',
'ata': 'I', 'aca': 'T', 'aaa': 'K', 'aga': 'R',
'atg': 'M', 'acg': 'T', 'aag': 'K', 'agg': 'R',
'gtt': 'V', 'gct': 'A', 'gat': 'D', 'ggt': 'G',
'gtc': 'V', 'gcc': 'A', 'gac': 'D', 'ggc': 'G',
'gta': 'V', 'gca': 'A', 'gaa': 'E', 'gga': 'G',
'gtg': 'V', 'gcg': 'A', 'gag': 'E', 'ggg': 'G'
}
I can of course count the amount of occurences of each codon but since there's more than one codon associated with each Amino Acid I really need the sum of specific codons.
for codons in aaDic:
s.count(codons)
(s is the sequence of a,t,c,g in the code above). For example:
tta,ttg,ctt,ctc,cta,ctg are all associated with the amino acid 'L', so I need to sum of all occurences of tta,ttg,ctt,ctc,cta,ctg to get the total amount of occurences of the amino acid 'L'.
I hope I am clear enough, it's a little hard to explain, especially after trying to do it so long for yourself and failing at it (which usually indicates you have little to no idea of what you are doing, at least that's the case with me :D)
EDIT:
Let me try to make myself somewhat more clear:
*
*We are given a sequence consisting exlusively of the letters A, T, C and G.
*We have to parse this sequence three by three.
suppose the sequence is "TTCTTACTC"
we get "TTC", "TTA", "CTC"
*We now look up these keys in the dictionary and we find the associated amino acids:
TTC is F
TTA is L
CTC is L
*We need to count and store in a list the number of F's, L's and any other value (FLIMVSPTAY*HQNKDECWRSG) in the dictionary.
The desired output would be a dictionary like so:
{L:total no. of the amino acid 'L' in the sequence, S:total no. of the amino acid 'S' in the sequence, ...}
A: If you use Python 2.7 or above, you can use collections.Counter to count the amino acids. First, split your base sequence into codons, then count the amino acids corresponding to each codon:
base_seq = "atcgtgagt"
codons = [base_seq[i:i + 3] for i in range(0, len(base_seq), 3)]
amino_acid_counts = collections.Counter(aaDict[c] for c in codons)
Note that the generator expression (aaDict[c] for c in codons) generates a sequence of amino acids, regardless by which codons they were encoded.
If you use an earlier version of Python, you can also use a plain dictionary for counting:
amino_acid_counts = dict.fromkeys(aaDict.values(), 0)
for c in codons:
amino_acid_counts[aaDict[c]] += 1
A: If you don't have 2.7+, you can still use a defaultdict:
counts = collections.defaultdict(int)
for k in aaDic:
counts[aaDic[k]] += 1
A: Try the following:
y = {}
for x in aaDic.items():
y[x[1]] = []
for x in aaDic.items():
y[x[1]].append(x[0])
Then you can find all the values with X keys with:
xkv = [ k for k in y.keys() if len(y[k]) == X ]
A: Using codons split from @sven-marnach:
base_seq = "atcgtgagt"
# split sequence, 3 by 3
codons = [base_seq[i:i + 3] for i in range(0, len(base_seq), 3)]
# for each codon we have, obtain his associated amino_acid from aaDic
amino_acids = map(aaDic.get, base_seq)
# here, amino_acids is ['I', 'V', 'S']
i_count = amino_acids.count('I')
# and so on
Then you can assemble your resulting dict with:
aa_names = set(aaDic.values())
return dict((aa_name, amino_acids.count(aa_name) for aa_name in aa_names))

fetch(UKOS.WMTS + "&request=GetCapabilities&version=2.0.0", {
headers: { Authorization: "Bearer " + UKOS.getToken() },
}).then(/* etc */);
I have read that the explicit use of 'async' and 'await' shouldn't be necessary when using 'fetch', but their use definitely alters the behaviour, though neither version works, as follows:
With 'async' and 'await' as above:
Error messages come from the access token being returned as 'undefined' before it could be returned by the CGI script, but after these the console.log statement, which has waited for the token, prints the right answer.
Without these keywords:
The console.log prints undefined before the error messages resulting from the undefined return value.
This is being tested using FF 96.0.3, but PaleMoon 29.4.4.4 does the same, IE dies much earlier, I suspect because it doesn't understand modern scripting syntax.
How can I force the return to wait for the correct value?
A: async functions always return promises. So code like { Authorization: "Bearer " + UKOS.getToken() } is going to be trying to concatenate a string with a promise, which is not what you want. You need to either call .then on the promise and put your code in the callback:
UKOS.getToken()
.then(token => {
return fetch(UKOS.WMTS + "&request=GetCapabilities&version=2.0.0", {
headers: { Authorization: "Bearer " + token },
})
})
.then(/* etc */)
Or you need to put your code in an async function, and await the promise:
async function someFunction() {
const token = await UKOS.getToken();
const response = await fetch(UKOS.WMTS + "&request=GetCapabilities&version=2.0.0", {
headers: { Authorization: "Bearer " + token },
})
/* etc */

luigi.rpc.RPCError: Errors (3 attempts) when connecting to remote scheduler 'http://localhost:8082'
sounds like try to ping central schedule, but be failed, then crashed, later tasks all be blocked, cannot run successfully.
and, some one else also meet the similar error, but his resolution not works.
Github - Failed connecting to remote scheduler #1894
A: I would try making the timeout a little longer if your central scheduler is getting overloaded. You could also increase retries and retry wait time.
in luigi.cfg
[core]
rpc-connect-timeout=60.0 #default is 10.0
rpc-retry-attempts=10 #default is 3
rpc-retry-wait=60 #default is 30
You may also want to add a watch have the scheduler process automatically restart on crash.
A: Have you configured the central scheduler properly? See the docs:
https://luigi.readthedocs.io/en/stable/central_scheduler.html
If not, try using the local scheduler by specifying --local-scheduler from the command line.

I have been using setdiff() from rgeos for many years, but I've found a quirk in redoing my work. What I basically want to do is to overlay a transparent hole over an Akima generated image map.
I find that I need to specify one of the hole vertices slightly larger than the polygon in which the hole is to be cut.
Here is the example script:
library(rgeos)
Changing 'maxy' to 2.1 provides the desired effect. Why not for 1.9?
maxy <- 1.9
maxy <- 2.1
x1 <- c(1, 1, 2, 2, 1)
y1 <- c(1, 2, 2, 1, 1)
xy1 <- cbind(x1, y1)
p1 <- as(xy1, "gpc.poly")
plot(p1, main="p1")
x2 <- c(1.1, 1.5, 1.9, 1.1)
y2 <- c(1.1, maxy, 1.1, 1.1) # NOTE: 'maxy' is here!
xy2 <- cbind(x2, y2)
p2 <- as(xy2, "gpc.poly")
plot(p2, main="p2")
plot(setdiff(p1, p2),
poly.args = list(col = "grey"),
main="setdiff(p1, p2)", asp=1)
If this cannot be fixed, is there another way to accomplish the same?
Thanks ahead of time.

I read this answer, but isn't there something from 2017 so far?
A: From the documentation as mentioned here, the TableReference takes the following parameters (dataset_ref, table_id). From your code snippet it looks like the braces are incorrectly placed.
with beam.Pipeline(options=pipeline_options) as pipeline:
dataset_ref = bigquery.DatasetReference('my-project-id', 'some_dataset')

A: This is a tough one, but I can think of a solution which involves invoking a script immediately after a merge operation (but before any manual resolving).
First off, the cache of conflict resolutions (.git/rr-cache) is stored by blob hash rather than by file path. There is nothing to indicate which file the resolutions actually came from, so I think hacking away at that directory would not be a viable solution.
This quote from maintainer Junio Hamano also hits on the fact that rerere is per-merge and not per-file:
There is no "I do not care if there are good resolutions remembered
that do not have anything to do with the current merge, just remove
all of them"---that is what "rm -fr .git/rr-cache" is for.
...which of course is not useful for you because selectively deleting files from .git/rr-cache is not well suited for automation in your use-case.
The feature to exploit may be the forget sub-command which takes a pathspec. The "forgetting" can only happen during the context of a merge however, which makes it fundamentally different than something like .gitignore which you can apply statically.
But, conceivably you could have a post-merge hook that invokes a script which:
Iterates over the conflicted files:
git diff --name-only --diff-filter=U
For every file that you want to "un-rerere", forget it:
git rerere forget -- path/to/file
...and restore the conflict:
git checkout -m path/to/file
Then, continue on with the merge per-usual leaving the rerere resolutions for the files you want remembered intact.
The list of files to have "rerere remembered" could be checked into the repository (perhaps in a file called .reremember) and queried from the script.

I have a collection C, with an array of attributes A1.
Each attribute has an array of subattributes A2.
How can I add a subdocument to a specific C.A1 subdocument ?
A: Here is an example.
db.docs.insert({_id: 1, A1: [{A2: [1, 2, 3]}, {A2: [4, 5, 6]}]})
If you know the index of the subdocument you want to insert, you can use dot notation with the index (starting from 0) in the middle:
db.docs.update({_id: 1}, {$addToSet: {'A1.0.A2': 9}})
This results in:
{
"A1" : [
{
"A2" : [
1,
2,
3,
9
]
},
{
"A2" : [
4,
5,
6
]
}
],
"_id" : 1
}
A: Yes, this is possible. If you post an example I can show you more specifically what the update query would look like. But here's a shot:
db.c.update({ A1: value }, { $addToSet: { "A1.$.A2": "some value" }})
I haven't actually tried this (I'm not in front of a Mongo instance right now) and I'm going off memory, but that should get you pretty close.
A: Yes, $push can be used to do the same. Try below given code.
db.c.update({ A1: value }, { $push: { "A1.$.A2": num }});

Conclusion
When list size reach 10000 items then so far only Schaffner's implementation is usable.
And because it's fairly simple to read I will pick it as the most elegant solution.
A: I can think of this, but no idea what-so-ever how it will scale compared to your existing solution:
<T> T notUsedRandomItem(List<T> allItems, List<T> usedItems) {
// this is only needed because your input List might not support removeAll
List<T> left = new ArrayList<>(allItems);
List<T> right = new ArrayList<>(usedItems);
left.removeAll(right);
return left.get(new Random().nextInt(left.size()));
}
One thing to keep in mind is that sorted is a stateful operation, so it will sort the entire "diff", but you only retrieve one element from that. Also your Comparator is wrong, for the same two values o1 and o2 you might say they are different - this can break in mysterious ways.
A: You should use HashSets to improve performance:
<T> T notUsedRandomItem(List<T> allItems, List<T> usedItems) {
Set<T> used = new HashSet<>(usedItems);
Set<T> all = new HashSet<>(allItems);
all.removeIf(used::contains); // or all.removeAll(used)
if (all.isEmpty()) throw new RuntimeException("Did not find item!");
int skip = new Random().nextInt(all.size());
Iterator<T> it = all.iterator();
for (int i = 0; i < skip; i++) it.next();
return it.next();
}
This removes elements from the all set if they belong to the used set. As Set.removeIf and Set.contains are being used, the removal of elements is optimal w.r.t performance. Then, a random number of elements is skipped in the resulting set, and finally, the next element of the set is returned.
Another approach is to shuffle the all list first and then simply iterate and return the first element that doesn't belong to the used set:
<T> T notUsedRandomItem(List<T> allItems, List<T> usedItems) {
Set<T> used = new HashSet<>(usedItems);
List<T> all = new ArrayList<>(allItems);
Collections.shuffle(all);
for (T item : all) if (!used.contains(item)) return item;
throw new RuntimeException("Did not find item!");
}
EDIT: Checking the last snippet of code, I now realize that there's no need to shuffle the whole list. Instead, you could randomize the indices of the allItems list and return the first element that doesn't belong to the used set:
<T> T notUsedRandomItem(List<T> allItems, List<T> usedItems) {
Set<T> used = new HashSet<>(usedItems);
return new Random().ints(allItems.size(), 0, allItems.size())
.mapToObj(allItems::get)
.filter(item -> !used.contains(item))
.findAny()
.orElseThrow(() -> new RuntimeException("Did not find item!"));
}
A: The Comparator you've passed into the sorted intermediate operation seems wrong and strange way to use a Comparator to my eyes anyway; which relates to what @Eugene has mentioned in his post.
Thus, I'd recommend you avoid any type of pitfalls and always use an API the way it's intended to be used; nothing more.
if you really want a random element from the said list; the only way that is possible is to find all the distinct elements of the two lists. so we cannot improve the speed in this aspect.
once this is done we simply need to generate a random integer within the range of the list containing the distinct elements and index into it given there is at least one element contained in it.
Though I have to admit there are probably better ways to accomplish the task at hand without the use of streams; here's how I have modified your code slightly to remove the misuse of .sorted((o1, o2) -> new Random().nextInt(2) - 1).
<T> T notUsedRandomItem(List<T> allItems, List<T> usedItems) {
List<T> distinctItems = allItems.stream()
.filter(item -> !usedItems.contains(item))
.collect(toList());
if(distinctItems.size() == 0) throw new RuntimeException("Did not find item!");
return distinctItems.get(new Random().nextInt(distinctItems.size()));

There are the following Classes:
public class Tag
{
public string Id{get;set}
public string Tag{
get{ return Id;}
}
public class AnEntity
{
[...]
public virtual ICollection<Tag> Tags{ get; set;}
}
I query the database this way:
var query = from entity in db.AnEntities
where [...]
select new {
[...]
Tags = entity.Tags.Select(tag => tag.Id).ToList()
}
If I execute the query now with await query.ToListAsync() the performance is quite reasonable.
However if i want to filter the search and return only the AnEntities that cointains all of a given set of tags, the performance is really bad. I do the "contains all query" this way:
var filters = new List<string>(){"Filter1", "Filter2"};
from filtent in query
where filters.Intersect(filtent.Tags).Count() == filters.Count
select filtent;
Is there a cleverer way to do this 'contains all' query?
Edit: I also thought about replace the Tags with a comma-seperated string but I'm not sure how i can run a 'contains all' query directly on the database. This is important, because after the filterquery there are some more queries and i dont want to receive entities from the database that dont contains all the given filters. Is there a way i could do it with a comma seperated string or something like that?
Many thanks for hints!
A: This is because EF creates a monstrous query with Intersect. It somehow has to translate the list filters into SQL and it does that by UNION-ing single-value SELECTs for each element in the list. And that happens a number of times in one query.
I've experienced that statements like Intersect, Except and sometimes All and Any are often better avoided and replaced by a solution using Contains, because Contains is always translated into an IN statement. In your case that would be
from filtent in query
where filtent.Tags.All(f => filters.Contains(f) )
select filtent
I'm sure this will produce a much better query that also performs much better. In this case, the All statement is translated into a harmless NOT EXISTS.

I am new to Node and JavaScript and I am trying to understand the different uses of package.json and package-lock.json. Before you read any further, no, I am not merely just asking for a summary of what their difference is here.
After doing some homework, my understanding of them is as follows:
*
*you want to commit both to source control, so neither should be mentioned in the .gitignore
*package.json describes your project and can do some lightweight dependency management, for instance, specifying that you want the latest version of the fizzbuzz package, or you want the latest 3.10.x version of the fizzbuzz package
*package-lock.json is purely for dependency management and goes into detail about which specific dependencies your project should use; for instance if you specify you want the latest 3.10.x version of fizzbuzz in your package.json file, the package-lock.json file might specify fizzbuzz-3.10.24, etc.
*you do directly modify/edit your package.json file, but you only let NPM and perhaps other command line tools modify your package-lock.json (hence no human being should ever edit package-lock.json)
Are these statements correct? If not, can someone please provide some details as to how/where my understanding is going awry?
A: Small answer
Your understanding is correct.
To run a basic Nodejs project you only need package.json file on your project, I mean it's required.
The package.json is used to keep the dependencies of the project. Which also defines project properties like description, author, license information, scripts, etc.
The package-lock.json is used to keep dependencies in a specific version number. It records the exact version of each installed package which allows you to install the same version of packages on different environments.
Brief answer
Why package-lock.json is created?
When you install a package in your project using the below command. for example
npm install node-sass --save
, it will install the exact latest version of that package in your project and save the dependency in the package.json with a carat (^) sign.
"node-sass": "^6.0.0"
Carat (^) means it will support any higher version with the major version. Here, package-lock.json is created for locking the dependency with the installed version, in this case 6.
What is the use of package-lock.json?
As mentioned above it records the exact version of each installed package which allows you to re-install them. This allows you to generate the same results in different environments. For that, we should use the package-lock.json file to install dependencies.
Why should we commit package-lock.json with our project source code (to Git)?
During deployment, when you run npm i (or npm install) on your server or whatever environment with the same package.json file without the package-lock.json, the installed packages might have a higher version now from what you had intended. In that case, if your code targeted a specific version of some of those packages you might have a problem.

What is wrong with my tests, and how can I test for the value of a variable set by the user?
A: Don't quote the variable name when passing it to eq:
(eq mu4e-sent-messages-behavior 'delete)
The problem with this piece of code:
(when (member mu4e-sent-messages-behavior '(sent)) t nil)
is that when will either return nil (if the condition is false) or the last value of the body (if the condition is true), which in this case is nil - so this piece of code will always return nil. Use if instead of when, and you should see it returning t.

Issue I am having is they have onboarded a new customer with a new feed. The customers feed which they are now sending me are correct, Although their XML files are missing the declaration at the top.
Example of Declaration missing
<?xml version="1.0" encoding="UTF-8"?>
This is stopping the feed from processing and displaying on the website.
If I manually add the Declaration and re upload it works.
Now the customer is saying they have never had the headers and it works for other 3rd party companies.
Is there a way to add the header once receiving the files, the feed processor & FTP server are in c#, dotnet3.1

I have a CSV file of exposures for days of the year e.g. 01/11/2002 (DMY).
I want these imported into Stata and it to recognise that it is a date variable. I've been using:
insheet using "FILENAME", comma
But by doing this I am only getting the dates as labels rather than names of the variables. I guess this is because Stata doesn't allow variable names to start with numbers. I have tried to reformat the cells as Dates in Excel and import but then Stata thinks the whole column is a Date and changes the exposure data into dates.
Any advice on the best course of action is appreciated...
A: As commented elsewhere, I too think you probably have a dataset that is best formatted as panel data. However, I address first the specific problem I think you have according to your question. Then I show some code in case you are interested in switching to a panel structure.
Here is an example CSV file open as a spreadsheet:
And here the same file, open in a text editor. Imagine the ; are ,. This is related to my system's language settings.
Running this (substitute delimiter(";") for comma, in your case):
clear all
set more off
insheet using "D:\xlsdates.csv", delimiter(";")
results in
which I think is the problem you describe: dates as variable labels. You would like to have the dates as variable names. One solution is to use a loop and strtoname() to rename the variables based on the variable labels. The following goes after importing with insheet:
foreach var of varlist * {
local j = "`: variable l `var''"
local newname = strtoname("`j'", 1)
rename `var' `newname'
}
The result is
The function strtoname() will substitute out the ilegal characters for _'s. See help strtoname.
Now, if you want to work with a panel structure, one way would be:
clear all
set more off
insheet using "D:\xlsdates.csv", delimiter(";")
* Rename variables
foreach var of varlist * {
local j = "`: variable l `var''"
local newname = strtoname("`j'", 1)
rename `var' `newname'
}
* Generate ID
generate id = _n
* Change to long format
reshape long _, i(id) j(dat) string
* Sensible name
rename _ metric
* Generate new date variable
gen dat2 = date(dat,"DMY", 2050)
format dat2 %d
list, sepby(id)
As you can see, there's no need to do anything beforehand in Excel or in an editor. Stata seems to be enough in this case.
Note: I've reused code from http://www.stata.com/statalist/archive/2008-09/msg01316.html.
A further note on performance: A CSV file with 122 variables or days (columns) and 10,000 observations or subjects (rows) + 1 header row, will produce 1,220,000 observations after the reshape. I have tested this on some old machine with a 1.79 GHz AMD processor and 640 MB RAM and the reshape takes approximately 8 minutes. Stata 12 has a hard-limit of 2,147,483,647 observations (although available RAM determines if you can actually achieve it) and Stata SE of 32,767 variables.
A: There seems to be some confusion here between the names that variables may have, the values that variables may have and the types that they may have.
Thus, the statement "Stata doesn't allow variables to start with numbers" appears to be a reference to Stata's rules for variable names; if it were true, numeric variables would be impossible.
Stata has no variable (i.e. storage) type that is a date. Strictly, it has no concept of a date variable, but dates may be held as strings or numbers. Dates may be held as strings insofar as any text indicating a date is likely to be a string that Stata can hold. This is flexible, but not especially useful. For almost all useful work, dates need to be converted to integers and then assigned a display format that matches their content to be readable by people. Stata has various conventions here, e.g. that daily dates are held as integers with 0 meaning 1 January 1960.
It seems likely in your case that daily dates are being imported as strings: if so, the function date() (also known as daily()) may be used to convert to an integer date. The example here just uses the minimal default display format for daily dates: friendlier formats exist.
. set obs 1
obs was 0, now 1
. gen sdate = "12/03/12"
. gen ndate = daily(sdate, "DMY", 2050)
. format ndate %td
. l
+----------------------+
| sdate ndate |
|----------------------|
1. | 12/03/12 12mar2012 |
+----------------------+
If your variable names are being misread, as guessed by @ChrisP, you may need to tell us more. A short and concrete example is worth more than a longer verbal description.

Example: imagine you have this
struct C { /* a class */ };
template<class T> struct S {
typedef C type; // S<T>::type is a type
};
What's bothering me is this:
template<class T> struct Typedef {
typedef typename S<T>::type MyType; // needs typename
};
template<class T> struct Inheritance
: S<T>::type // doesn't need typename
{ };
In both cases the parser should expect a type, so it could parse S<T>::type as one. Why does it only do so for inheritance, and not for typedefs? The pattern seems the same to me:
typedef $type$ $new_symbol$;
class $new_symbol$ : $type$ { $definition$ };
Or is there a usage of typedef I'm not aware of, which make this ambiguous?
PS: I'm pretty sure this has already been asked, but I can't find it (there's a lot of noise related to the typename keyword). This question is only about the syntax, not whether it's better to use inheritance or typedefs. I appologize in advance if there's a duplicate.
A: The reason is that the typedef syntax is more variable than the inheritance syntax. Normally you would write typedef first, and the type name second. But the order is actually unimportant. To wit, the following is a valid typedef:
int typedef integer_type;
Now consider what happens if we use a dependent name:
S<T>::type typedef integer_type;
Without doing some non-trivial lookahead, the parser cannot know that S<T>::type refers to a type name here (because it hasn’t yet seen the typedef), so by the disambiguation rules it infers a value. For consistency in the grammar, there is no special case for prefixed typedef (which, you are right, is unambiguous). There could be a special case, but there simply isn’t.

import nltk
f=open('word-freq-utf8-new.txt','rU')
text=f.read()
text1=text.split()
abst=nltk.Text(text1)
abst.concordance('سلام')
A: The nltk does not yet work really well with unicode, although they are working on it. As a bit of a quick fix, you can create a subclass for the concordance and overwrite the print_concordance method to make sure you are encoding/decoding at the right times for processing and display purposes. Here is a really quick fix, assuming you have already imported the nltk (I am using as an example part of a unicode Greek text):
>>> tokens = re.findall(ur'\w+', t.decode('utf-8'), flags=re.U) # I did this to make sure I was working with a decoded text. If you are working with an encoded text, skip this. `t` is the equivalent of your `text`.
>>> class ConcordanceIndex2(nltk.ConcordanceIndex):
'Extends the ConcordanceIndex class.'
def print_concordance(self, word, width=75, lines=25):
half_width = (width - len(word) - 2) // 2
context = width // 4 # approx number of words of context
offsets = self.offsets(word)
if offsets:
lines = min(lines, len(offsets))
print("Displaying %s of %s matches:" % (lines, len(offsets)))
for i in offsets:
if lines <= 0:
break
left = (' ' * half_width +
' '.join([x.decode('utf-8') for x in self._tokens[i-context:i]])) # decoded here for display purposes
right = ' '.join([x.decode('utf-8') for x in self._tokens[i+1:i+context]]) # decoded here for display purposes
left = left[-half_width:]
right = right[:half_width]
print(' '.join([left, self._tokens[i].decode('utf-8'), right])) # decoded here for display purposes
lines -= 1
else:
print("No matches")
If you are working with a decoded text, you will need to encode the tokens like so:
>>> concordance_index = ConcordanceIndex2([x.encode('utf-8') for x in tokens], key=lambda s: s.lower()) # encoded here to match an encoded text
>>> concordance_index.print_concordance(u'\u039a\u0391\u0399\u03a3\u0391\u03a1\u0395\u0399\u0391\u03a3'.encode('utf-8'))
Displaying 1 of 1 matches:
ΚΑΙΣΑΡΕΙΑΣ ΕΚΚΛΗΣΙΑΣΤΙΚΗ ΙΣΤΟΡΙΑ Euse
Otherwise, you can simply do this:
>>> concordance_index = ConcordanceIndex2(tokens, key=lambda s: s.lower())
>>> concordance_index.print_concordance('\xce\x9a\xce\x91\xce\x99\xce\xa3\xce\x91\xce\xa1\xce\x95\xce\x99\xce\x91\xce\xa3')
Displaying 1 of 1 matches:

Let's say that we have stored some data in the table. For example:
Column A Column B
x1 y1
x2 y2
x3 y3
If I try to send some data like (x1, y4), will y1 be set to y4?
If not is there a setting to do it from phpMyAdmin?
Or Do I need to use UPDATE?
A: You should use UPDATE or INSERT ON ON DUPLICATE KEY UPDATE
MORE INFO @ http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html
A: trying to insert a row with an existing primary key will cause an error, and that's exactly why no one uses things that might be duplicated as primary keys, to change the value of the existing row, you must use UPDATE, there is no other solution, but if you want to insert a new row, my advice is to go main stream, either use an autoincremented id as primary key, or use things like GUID(windows only).

const EventEmitter = require('events');
const WebSocket = require('ws');
const myEmitter = new EventEmitter();
const ws = new WebSocket('wss://someurl');
ws.on('message', (data) => {
........
/*
preprocess and do the mongodb stuff
*/
myEmitter.emit('someevent', data)});
});
My question is, how can I listen for such an event in my React client? If I stick with this approach, do I need to pass in myEmitter to my React components?
I am new to React so please let me know if there is any better way to solve the problem.
A:
do I need to pass in myEmitter to my React components?
no... your client side and serverside code should be separate. You can use a client-side SocketIO app like socket.io.
if you're going to be listening for a bunch of different events in different components, consider using an enhancer style wrapper
function withSocket (event?, onEvent?) { // note: this is TS
return (Component) => {
class WithSocketEvent extends Component {
constructor (props) {
super(props)
this.socket = io.connect(SOCKET_ENDPOINT)
}
componentDidMount () {
if (event && onEvent) {
this.socket.on(event, onEvent)
}
}
componentWillUnmount () {
this.socket && this.socket.close()
}
render () {
return (
<Component
{ ...this.props }
socket={ this.socket }
/>
)
}
}
return WithSocketEvent
}
}
// usage
class HasSocketEvent extends Component {
componentDidMount () {
// handle the event in the component
this.props.socket.on("someEvent", this.onSocketEvent)
}
onSocketEvent = (event) => {
}
render () {
}
}
// handle the event outside the component
export default withSocket("someEvent", function () {
// so something
})(HasSocketEvent)
// or
export default withSocket()(HasSocketEvent)

I want to create UUID.
But I can't find any c# version of 'CFUUIDXXXX'.
Anyone knows what the class name is?
If it doesn't exist, I have a question.
Looking Xamarin's API document is fastest way to know whether it exist or not?
If it doesn't exist, It seems like that Xamarin.iOS doesn't inject all the class from iOS native class?
Is it correct?
I also know about Guid. But I was told that there is no guarantee it's unique.
And also there is "UIDevice.CurrentDevice.IdentifierForVendor".
Is it good enough to use as UUID?
Thanks.
A: You can use NSUUID(in Xamarin NSUuid) instead.
This is the new younger cousin to CFUUID. NSUUID just popped up in iOS 6. It is pretty much exactly the same as CFUUID except it has a nice, modern Objective-C interface.
Here is a good comparison of all Id-Types: https://possiblemobile.com/2013/04/unique-identifiers/

/root/document/{ids}?fields={fields}
/root/externaldocument/{ids}?fields={fields}
to map to the same interface member:
Documents GetDocuments(string ids, string fields)
I have tried putting a wildcard into a literal URL segment:
[OperationContract]
[WebGet(UriTemplate = "/root/*document/{ids}?fields={fields}")]
Documents GetDocuments(string ids, string fields)
However, this is not valid and I get the following exception:
The UriTemplate '/root/*document/{ids}?fields={fields}' is not valid; the
wildcard ('*') cannot appear in a variable name or literal... Note that a
wildcard segment, either a literal or a variable, is valid only as the last
path segment in the template
If I wrap the wildcard segment in a template brace:
[OperationContract]
[WebGet(UriTemplate = "/root/{*document}/{ids}?fields={fields}")]
Documents GetDocuments(string ids, string fields)
Then I get an exception because there is no such input parameter in the method arguments:
Operation 'GetDocuments' in contract 'IAPIv2' has a UriTemplate that expects a
parameter named 'DOCUMENTS', but there is no input parameter with that name
on the operation.
My workaround is simply to have two entries, pointing to different methods, and then have the methods call a common implementation:
[OperationContract]
[WebGet(UriTemplate = "/root/document/{ids}?fields={fields}")]
Documents GetDocuments(string ids, string fields)
[OperationContract]
[WebGet(UriTemplate = "/root/externaldocument/{ids}?fields={fields}")]
Documents GetExternalDocuments(string ids, string fields)
But this seems kind of ugly.
I have read the documentation and cannot find this point specifically address. Is there any way I can have a wildcard literal segment in WCF? Or is this not possible in WCF?
A: As it turned out, the two entry points needed to have slightly different functionality. So I needed to capture which URL was used to enter the method. What I ended up doing was the following:
[OperationContract]
[WebGet(UriTemplate = "/root/{source}ocuments/{ids}?fields={fields}")]
DocumentCollection GetDocumentsById(string source, string ids, string fields);
Both URLs:
/root/document/{ids}?fields={fields}
/root/externaldocument/{ids}?fields={fields}
map to the same URL template, and thus I needed to have only a single entry with a single UriTemplate in my interface.
The "source" input parameter captures either "d" if the second segment is "documents or "externald" if the second segment is "externaldocuments". Thus by inspecting this input parameter, the method can react appropriately, depending upon which URL was used to reach the method.
Note that I could not use the following for the UriTemplate:
[WebGet(UriTemplate = "/root/{source}documents/{ids}?fields={fields}")]
because in this case, the incoming URL
/root/document/{ids}?fields={fields}
would not match the template, even though the template matches if an empty string ("") is used for the source input parameter. Apparently the UriTemplate matching algorithm requires there to be at least one character in a parameter capturing group for there to be a match.

Thank You
A: You should need to check the user is login status in the dashboard. For simply, you can try the below answer. As using Laravel, why can't you use the middleware property?
Middleware provide a convenient mechanism for filtering HTTP requests entering your application. For example, Laravel includes a middleware that verifies the user of your application is authenticated. If the user is not authenticated, the middleware will redirect the user to the login screen. However, if the user is authenticated, the middleware will allow the request to proceed further into the application.
public function dashboard()
{
$user = Session::get('user');
if($user)
return view('user.dashboard',['data'=>$user]);
else
return redirect('/login');

There is only one call to database and after that its using existing store from cache. How to make it reload from database every-time(or at least every-time when we reopen the display). Below is the code.
//store
Ext.define('NetworkStore', {
extend: 'Ext.data.Store',
alias: 'NetworkStore',
fields: ['Id', 'value'],
storeId: 'NetworkStore',
autoLoad: true,
proxy: {
type: 'ajax',
useDefaultXhrHeader: false,
actionMethods: { create: "POST", read: "GET", update: "POST", destroy: "POST" },
headers: { 'Content-Type': 'application/x-www-form-urlencode' },
limitParam: false,
startParam: false,
pageParam: false,
extraParams: {
Style: 1
},
url: 'url',
reader: {
type: 'json'
}
}
});
xtype: 'combo',
name: 'NetworkIDList',
store: Ext.create('NetworkStore').load({
params: {
Style: 3
}
}),
A: The offical docs in lastQuery offer:
listeners: {
beforequery: function (qe) {
delete qe.combo.lastQuery;
}
}
here is the full soure:
/**
* @property {String} lastQuery
* The value of the match string used to filter the store. Delete this property to force
* a requery. Example use:
*
* var combo = new Ext.form.field.ComboBox({
* ...
* queryMode: 'remote',
* listeners: {
* // delete the previous query in the beforequery event or set
* // combo.lastQuery = null (this will reload the store the next time it expands)
* beforequery: function(qe){
* delete qe.combo.lastQuery;
* }
* }
* });
*
* To make sure the filter in the store is not cleared the first time the ComboBox trigger
* is used configure the combo with `lastQuery=''`. Example use:
*
* var combo = new Ext.form.field.ComboBox({
* ...
* queryMode: 'local',
* triggerAction: 'all',
* lastQuery: ''
* });
*/
A: Add the desired logic to the list expand event handler.
Fiddle
xtype: 'combo',
name: 'NetworkIDList',
listeners: {
expand: function () {
this.getStore().load()
}
},
store: Ext.create('NetworkStore').load({
params: {
Style: 3
}
})
A: If we pass store as given below it will always get store from db not from cache.
store: {
type: 'NetworkStore',
proxy: {
extraParams: {
Style: 3
}
}
}
A: remoteFilter: true
true if want to load datas from the server side on each expand of combobox,
false if you want to load data locally after once it is loaded.
if remoteFilter property is not set in the store it defaults to false.
soo setting this property to true might solve the issue
A: First, you need to convert your desire to a systematic logic.
"at least every-time when we reopen the display"
Like the following logic:
*
*Listen to the widget's event, which means to "when we reopen the display"
*Reload the widget's store
{
xtype: 'combo',
name: 'NetworkIDList',
store: Ext.create('NetworkStore').load({
params: {
Style: 3
}
}),
//Add this:
afterRender: function(){
//Just do this to load the store
this.getStore().load();

afterRender is one of sample listeners which can be declared as a method. There are many other event listeners you can use to place your code to load the widget's store again and again as you want.
see https://docs.sencha.com/extjs/7.0.0/modern/Ext.Widget.html#method-afterRender
and .load() is the ProxyStore's method which can be used to first load manually or reload the store.
see https://docs.sencha.com/extjs/7.0.0/modern/Ext.data.ProxyStore.html#method-load
Hope it help.

As you know any user can dump database from phone and see its structure and data.
Does exist any way to prevent database dump from Android phones?
I avoid that anynone can have a look at database data (and then copy it) using any SQLite explorer.

With Bootstrap
I tired Bootstap with text and it is working. But i couldn't figure out how to do it with check box.
$(document).ready(function ()
{
$("#myInput").on("keyup", function ()
{
var value = $(this).val().toLowerCase();
$("#activityTable tr").filter(function ()
{
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
});
});
Above code only works with text information.
Does anyone knows how to update this code for checkbox please
A: You can give an id to the checkbox and then get it's state. Let's say it's id is chkBox then you will have to write like:
var isChecked = $("#chkBox").is(':checked');
and then use it in your filter function:
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1
&& (isChecked && $(this).find('input:checkbox').is(':checked')));
and if you meant was to show only rows where checkbox state is checked when user types in fitler box then:
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1
&& $(this).find('input:checkbox').is(':checked')
);
Now this will look in the tr for checkbox and if it is checked that row will be toggled.

The sample test case passes. It means that the postList in fetched Tag is also eagerly fetched and filled.
Is Spring data repository's methods eagerly fetching by default?

It is very simple class that has methods for:
creating file,
opening file
closing file
saving file
writing to file
etc
etc
There are some options i use when writing my text to file such as font size, color and max words.
These options are passed to the constructor.
Should I split this class in to two seperated classes:
fileMaker
fileMakerOptions
and use fileMakerOptions object hold responsibility for text size etc and pass to the constructor of fileMaker?
or would it be best to have file maker encapsulate everything related to making the file including the style options
A: If your class is simple. And if there are only few options. Then no, you should not create new class. Overrefactoring is very bad.
A: You should provide more information about your main class responsibility as far as count of options you want to handle. Anyway - the general idea of creating new additional instances is delete options handling responsibility from your main 'class' responsibility.
For me I decide, if the amount of options greater then 4-5 - then I creating separate option entity.
A: I only split up classes when an existing class becomes too difficult or gettign too many properties of functions OR when I know beforehand that it will be extended a lot.
In your case it depends on the complexity and amount of functions/properties.

mvn clean compile
For some calsses I get multiple versions of the same class, example
./classes/com/.../MyClass$1$1.class

./classes/com/.../MyClass$1$11.class
./classes/com/.../MyClass$1$12.class
./classes/com/.../MyClass$1$13.class
./classes/com/.../MyClass$1$14.class
etc.
Why is this happening?
A: The $1 notation is for anonymous inner classes. Running javac will result in the same sort of output.

For example, the default value of the input box is False but when user clicks on the save button, the value in the input box changes to True.
Need help in solving the condition logic.
function change()
{
var change = document.getElementById("check");
if (change.value == "false")
{
document.test.savereport = "True";
document.test.submit();
}
else
{
change.value = "false";
}
}
<form name="test" method="post">
<input type="text" name="savereport" value="False" />
</form>
<div align="center">
<button type="button" value="false" id="check" onclick="change()" />Save</button>
</div>
A: I'm rusty with the exact syntax but the following code should do
function change()
{
var change = document.getElementById("check");
if (change.value == "1")
{
change.value = false
document.test.savereport = "True";
document.test.submit();
}
else
{
change.value = true
}
}
A: I don't understand why you need to go through all the trouble of reading values for this particular requirement.
You are reading the value, comparing it to False, leaving it as is if so or if True, you change it to False.
Hence essentially, you are just leaving the value to be False no matter what the earlier value was.
So, simply change the value in savereport upon click of the button.
<script>
function change() {
document.getElementsByName("savereport")[0].value = 'True';
}
</script>
<form name="test" method="post">
<input type="text" name="savereport" value="False" />
</form>
<div align="center">
<button type="button" value="false" id="check" onclick="change()" >Save</button>
</div>
A: Apart from removing self-closing of button tag, replace
document.test.savereport = "True";
with
document.test.elements[ "savereport" ].value = "true"
Demo
function change() {
var change = document.getElementById("check");
if (change.value == "false") {
document.test.elements["savereport"].value = "True";
//document.test.submit();
} else {
change.value = "true";
}
}
<form name="test" method="post">
<input type="text" name="savereport" value="False" />
</form>
<div align="center">
<button type="button" value="false" id="check" onclick="change()"> Save </button>
</div>
A: The code at Question does not set the .value of <input type="text" name="savereport" value="False" /> element.
You can set the value of <input type="text" name="savereport" value="false" /> element to "false" and evaluate boolean false as a string to check for equality.
<form name="test" method="post">
<input type="text" name="savereport" value="false" />
</form>
<div align="center">
<button type="button" value="false" id="check" onclick="change()">Save</button>
<script>
var input = document.test.savereport;
function change() {
if (input.value === String(false)) {
input.value = true;
// document.test.submit();
} else {
input.value = false;
}
console.log(input.value);
}
</script>
</div>

this is loginctrl (Login Controller)
'use strict';
angular.module('dreamflow').controller('LoginCtrl', ['$scope', 'LoginService',
function($scope, LoginService) {
$scope.title = "Login";
$scope.master = {}
$scope.login = function() {
var user = {
username: $scope.username,
password: $scope.password
};
LoginService(user);
};
}
]);
this is loginService
angular.module('dreamflow')
.factory('LoginService', function($http, $location, $rootScope) {
return function(user) {
$http.post('/login',{
username: user.username,
password: user.password
}).then(function(response) {
if (response.data.success) {
console.log(response.data);
$rootScope.user = response.data.user;
$location.url('/');
} else {
console.log(response.data.errorMessage);
$location.url('/');
}
});
};
});
In the above code user details is coming after checking the success of response and then we are redirected to the home page. I want to access the user details coming in $rootScope.user in home page angular controller.
A: You can have a service which will hold the login username and the service will injected into both controllers as such:
jsfiddle with '$scope'
Also, I find that using 'this' instead of '$scope' is helpful in not mixing up controller scopes between each other in case you use more than one controller in the same place. There are also other reasons.
HTML:
<div ng-app="myApp">
<div ng-controller="ControllerOne as one">
<h2>ControllerOne:</h2>
Change testService.loginName: <input type='text' ng-model='one.myService.loginName'/> </br></br>
myName: {{one.myService.loginName}}
</div>
<hr>
<div ng-controller="ControllerTwo as two">
<h2>ControllerTwo:</h2>
myName: {{two.myService.loginName}}
</div>
</div>
JS:
app.service('testService', function(){
this.loginName = "abcd";
});
app.controller('ControllerOne', function($scope, testService){
this.myService = testService;
});
app.controller('ControllerTwo', function($scope, testService){
this.myService = testService;
});

default: this.apply( self, arguments ); break;
}
};
So does anyone know why?
A: Referencing the ECMAScript Language Specification 5.1 Edition (June 2011):
15.3.4.3 Function.prototype.apply (thisArg, argArray)
When the apply method is called on an object func with arguments thisArg and argArray, the following steps are taken:
*
*If IsCallable(func) is false, then throw a TypeError exception.
*If argArray is null or undefined, then
return the result of calling the [[Call]] internal method of func, providing thisArg as the this value and an empty list of arguments.
*If Type(argArray) is not Object, then throw a TypeError exception.
*Let len be the result of calling the [[Get]] internal method of
argArray with argument "length".
*Let n be ToUint32(len).
*Let argList be an empty List.
*Let index be 0.
*Repeat while index < n
*Let indexName be ToString(index).
*Let nextArg be the result of calling the [[Get]] internal method of
argArray with indexName as the argument.
*Append nextArg as the last element of argList.
*Set index to index + 1.
*Return the result of calling the [[Call]] internal method of func,
providing thisArg as the this value and argList as the list of
arguments.
15.3.4.4 Function.prototype.call (thisArg [ , arg1 [ , arg2, … ] ] )
When the call method is called on an object func with argument thisArg and optional arguments arg1, arg2 etc, the following steps are taken:
*
*If IsCallable(func) is false, then throw a TypeError exception.
*Let argList be an empty List.
*If this method was called with more than one argument then in left
to right order starting with arg1 append each argument as the last
element of argList
*Return the result of calling the [[Call]] internal method of func,
providing thisArg as the this value and argList as the list of
arguments.
As we can see, the format in which apply is specified is notably heavier and needs to do a lot more due to the need to change the format in which the arguments are given and how they are finally needed.
There are a number of checks in apply which are not necessary in call due to the difference of input formatting.
Another key point is the manner in which arguments are looped over (steps 4-12 in apply, implied in step 3 of call): the whole set-up for looping is executed in apply regardless of how many arguments there actually are, in call all of this is done only if needed.
Additionally it's worthwhile noting that the way in which step 3 in call is implemented isn't specified, which would help explain the drastic differences in different browser behavior.
So to shortly recap: call is faster than apply because the input parameters are already formatted as necessary for the internal method.
Be sure to read the comments below for further discussion.

How can I preconfigure this in docker so I do not have to do it each time?
A: Use Kibana create saved objects API to write a script and run it in a container or something like that:
kibana_endpoint=localhost
kibana_system_user_password="12345678"
curl -X POST \
"${kibana_endpoint}:5600/api/saved_objects/index-pattern/logstash" \
--header "kbn-xsrf: true" \
--header "Content-Type: application/json" \
--user "kibana_system:${kibana_system_user_password}" \
--data \
"
{
"attributes": {
"title" : "logstash-*",
"timeFieldName": "@timestamp"
}
}
"
A: You can use the index template to define a template, and next time whenever you create an index matching the pattern name defined in your template, it will have a settings and mappings defined in the template.

var ninja = ninject.Get<Ninja>();
But why can't I do this:
Type ninjaType = typeof(Ninja);
var ninja = ninject.Get<ninjaType>();
What's the correct way of specifying the type outside the call to Get?
A: Specifying type arguments is not a runtime thing, it's statically compiled. The type must be known at compile time. In your scenario, it is potentially unknown, or computed at runtime. Through reflection it is possible to construct a method call where you specify the type arguments, but it's unlikely you want to do that.
Also, most containers should have an overload that would look something like this:
Type ninjaType = typeof(Ninja);
var ninja = (Ninja)ninject.Get(ninjaType);
Finally, most containers should provide ways to specify in the container configuration, which type should be provided on certain conditions. I know that Ninject has a pretty DSL to conditionally specify which type should be returned under what circumstances. This would mean however, to code against an abstraction and let the container decide what is returned:
class DependencyConsumer {
ctor(IWarrior warrior) {
//Warrior could be a ninja, because e.g. you told NInject
//that the dependency should be filled that way for this class
}
}
A: Since the purpose of the T is to specify the type you want. Ninject receives your type T and calls typeof(T) on your behalf. I think that this way your code is shorter. Don't you think?

int val;
if (!(cin >> val));
I don't understand what the if(!()) stands for and also able to type a character.
A:
what does the ! mean after ...
! is a unary operator. In this case it is the logical NOT operator. If expression implicitly converted to bool results in true, then !expression is false and if expression implicitly converted to bool results in false, then !expression is true.
A: The ! operator in c++ is called NOT operator, it toggles true/false.
In the given code fragment:
int val;
if (!(cin >> val));
The "if" condition will be true when the input value(cin>>) is "not" an integer.
it can be further be clarified by the following code:
int val;
if (!(cin >> val))
cout << "not an integer";
else
cout <<"integer";
A: I think this should not work as
if(!(cin>>val))// this is similar to if((cin>>val)==false)
This mean if the the input was not integer or something similar.
I this what is really require is checking if is digit.
int val;
cin >>val;
if(!isdigit(val))
{
//goes in if false of else it skips the if statement.
}
This is just an assumption (could be wrong).If need correct ans more detail is required, like what is the goal or...!

I`m thinking where should I move this logic from if else block. How to do that Rails Way. Move that to helper??
Or is better way? Code below isn`t working.
A: Yes, a helper is the right place as the code seems to be about rendering only. So there is no business logic there. If you see yourself putting a lot of stuff like this into helpers, you could have a look at http://github.com/jcasimir/draper which is a gem that implements the presenter pattern.

<form method="post" name="Form1" action="default.asp" onsubmit="return processField();">
<input type="hidden" name="hiddentext1">
<input type="text" name="text1">
<input type="submit" value="Submit" id="button1">
</form>
And what I want is to call ProcessField function on the submit of the form. I know that ProcessField function works fine - tested it using an inline call. But now I want to attach the event via JavaScript. Below is my JavaScript code:
<script type="text/javascript">
if (window.addEventListener){
window.addEventListener('load', attachFormSubmit, false);
} else if (window.attachEvent){
window.attachEvent('onload', attachFormSubmit );
}
function attachFormSubmit(){
theForm = document.getElementById("Form1");
alert("attaching form submit");
if (theForm.addEventListener){
theForm.addEventListener('submit', CleanUpEID, false);
} else if (theForm.attachEvent){
theForm.attachEvent('onsubmit', CleanUpEID);
}
}
function ProcessField()
{
alert("processing field");
if (this.text1.value == '')
{
alert ("Please enter the value")
this.text1.focus()
return false
}
this.hiddentext1.value = this.text1.value;
// Disable button
with ($('button1')) {
value = "Processing ...";
disabled = true;
}
return true;
}
</script>
I have two issues with the above script:
*
*it attaches the event to the form multiple times - every time page reloads. I suspect there is a better place for my code but cannot figure it out.
*Keyword "this" in processField function comes up undefined. It works fine if I replace "this" with form name, but I was wondering what needs to be done in order for keyword "this" to work in this case.
I'd really appreciate if someone could point me in the right direction.
Thanks.
A: EDIT
OP had a series of questions that involve some fundamental concepts of JavaScript. I have provided some links that will hopefully answer those questions. See the end of this post.
Rewrote the code to demonstrate it actually works with a test server. With the syntax errors, you'd never get it working. The biggest error is you call processField() but you define a function called ProcessField(), JavaScript is case-sensitive.
In order to function for your purposes, you'll have to change the form's action of course. I had to validate it's input for a min of 5 and a max of 15 alphanumerics due to the test server's limits, so you'll want to change that as well probably.
*
*it attaches the event to the form multiple times - every time page reloads. I suspect there is a better place for my code but cannot figure it out
You are adding/attaching the eventListener/Handler to the window which makes your submit event global, plus you didn't provision any way to prevent default behavior, so any form and form elements that by default are triggered by a submit event will popup on the event chain. I added the eventListener to the form and then used stopPropagation(); to prevent any unintentional triggering during the bubbling phase.
*Keyword "this" in processField function comes up undefined. It works fine if I replace "this" with form name, but I was wondering what needs to be done in order for keywrod "this" to work in this case.
See explanation above concerning the typo of processField.*
Btw, I didn't bother adding the cross-browser crap attachEvent because IE8 is dead, and that 1% of the world can use IE9. If you want to cater to that 1% just apply attachEvent as you did in your code.

All is running, but quite often and absolutely random (even if I scroll very slowly), I get this error:
I/flutter (10990): EXCEPTION CAUGHT BY IMAGE RESOURCE SERVICE

And those images are skipped!
Is there a way to handle this error and force reload of those images missing?
Special thanks in advance
I've also tried with paginated listView, with minimum number of pages to be load at a time, but this doesn't solve and the error always returns randomly.

A: I was having exactly the same issue and was never able to figure out the cause of the issue.
I ended up using the Cached network image library which fixed my problems with image loading.
A: This issue still exists even though the issue on GitHub was closed:
This error really random and we couldn't know when it will become an error.
My solution to fix this issue is we can use FadeInImage to know when is the request image got the error Connection closed before full header was received, URI = we can handle it on imageErrorBuilder method.
I create a new Widget called UrlImage:
FadeInImage.memoryNetwork(
placeholder: kTransparentImage,
image: imageURL,
imageErrorBuilder: (context, error, stacktrace) { // Handle Error for the 1st time
return FadeInImage.memoryNetwork(
placeholder: kTransparentImage,
image: imageURL,
imageErrorBuilder: (context, error, stacktrace) { // Handle Error for the 2nd time
return FadeInImage.memoryNetwork(
fit: BoxFit.cover,
placeholder: kTransparentImage,
image: imageURL,
imageErrorBuilder: (context, error, stacktrace) { // Handle Error for the 3rd time to return text
return Center(child: Text('Image Not Available'));
},
);
},
);
More detail Widget, you can see the code below on my Gist:
https://gist.github.com/Robihamanto/5e0dd358d4da90603683ca74430aff8a
A: It may be because the widget is reused in the widget tree and thus interrupts the HTTP request. You could then use a key in your FutureBuilder or Image widget.
child: FutureBuilder<File>(
key: ValueKey(imageUrl), // or use UniqueKey()
...
A: The issue still exists as of writing this. I tried with CachedNetworkImage package and the result is same. Finally I ended up using extended_image and it works like charm. Have a look at the plugin here- https://pub.dev/packages/extended_image
I have completed ported my application to use this package. Loading, Error, Success events also can be handled easily like CachedNetworkImage

I would like to update this column to allow NULLs.
I have the following script to do this however I would like to check first if the column is already NULL (or NOT NULL), as it may have been changed previously.
ALTER TABLE [dbo].[aud]
ALTER COLUMN [actname] nvarchar(50) NULL
Any help appreciated.
A: select is_nullable from sys.columns c inner join sys.tables t on
t.object_id = c.object_id where t.name = 'aud' and c.name = 'actname'
Will give you a BIT representing whether it is nullable or not.
So you could switch on this like
IF EXISTS(SELECT * from sys.columns c inner join sys.tables t on
t.object_id = c.object_id where t.name = 'aud' and c.name = 'actname' AND
is_nullable = 1)
BEGIN
--What to do if nullable
END
ELSE
BEGIN
--What to do if not nullable
END
END
That of course assumes that the table and column exist at all...
A: There isn't really a need to do that, because if it's already Nullable, changing a column from Nullable to Nullable will have no negative effect.
However you can do it with this query:
SELECT is_nullable
FROM sys.columns
WHERE object_id=object_id('YourTable') AND name = 'yourColumn'
A: Use COLUMNPROPERTY to get column property . You may write something like
SELECT COLUMNPROPERTY(OBJECT_ID('dbo.aud'),'actname','AllowsNull') AS 'AllowsNull';

If I precompute the drill down levels I'm interested in, I have to put those values into a separate fact-table / measure group for each drill down level, or don't I? Is it possible to do this in a way that is transparent to the end user? So it should look like there is only one fact table and SSAS automatically selects the value from the correct fact table based on the drill-down level?
A: I found the answer in a Microsoft forum: http://social.msdn.microsoft.com/Forums/en-US/sqlanalysisservices/thread/d5998b23-936b-4e7b-b593-bd164b20c022
On the Calculate tab you can define a scope statement:
In this really trivial example, internet sales amount will be shown when reseller sales amount is chosen (at calendar quarters).
scope([Measures].[Reseller Sales Amount], [Date].[Calendar].[Calendar Quarter]);
this=[Measures].[Internet Sales Amount];
end scope;

TypeError: on_member_join() takes 1 positional argument but 2 were given
A: You don't get a Context parameter for the on_member_join event, only a Member parameter. Therefore, you'll need to access the Guild in some other way.
Fortunately, this can easily be done; Member objects have a guild attribute.
You can also simplify grabbing the Unverified role and welcome channel by using discord.utils.get. So, with those changes:
@commands.Cog.listener()
async def on_member_join(self, member):
role = discord.utils.get(member.guild.roles, name="Unverified")
await member.add_roles(role)
channel = discord.utils.get(member.guild.channels, name="welcome")
embed = discord.Embed(title=f"Welcome {member}", color=discord.Colour.blue())
await channel.send(embed=embed)

this.pictureBox1.ImageLocation = "d:\\*.png";
The directory alawys consists of single .png file, though it changes name periodically.
A: You can't use wildcards on a PictureBox, however Directory.GetFiles does support them. So you could use that like so:
string[] files = Directory.GetFiles(@"D:\", "*.png");
if (files.Length > 0) {
// File(s) were found. You can now either decide
// which one to display or just display the first
// one
pictureBox1.ImageLocation = files[0];
} else {
// No files found. Display a default image or something
}
A: The ImageLocation property is the path to a single image resource (file or url).
You can use Directory.GetFiles to enumerate the file(s) in the target folder using wildcards.
A: No. ImageLocation must specify the location of a single file to be displayed. If you wish to display multiple images, you will need multiple picture box controls.

Nignx is running uid 101 but serviceaccount directory owned by root user.
How to fix this error message?
Thanks
A: It's kinda odd, as I've tested I haven't experienced such a error.
You could use securityContext, set
*
*fsGroup: 101 or
*runAsUser/runAsGroup
But still the ingress-nginx sets appropriate securityContext (for example to bind on 80/443), so it should work.
A: As @sfgroups mentioned solution is to make nignx not running uid 101 but 0.
Add flag to installation command: --set controller.image.runAsUser=0.

On certain views in my rails app, I want to have other settings, like placeholders for example. I'm not sure if version 4 includes a lot of changes compared to some of the older ones, but here are some other stackoverflow references that I've used:
How do I add a placeholder attribute to an instance of CKEditor?
This one in particular suggests using CKEDITOR.replace("myeditor" , config ); to replace the placeholder, but that doesn't work for me. When I replace "myeditor" with the ID of my textarea element, such as this: CKEDITOR.replace("randomTextAreaID" , {placeholder: "Hello World"} );, I get this error:
Uncaught The editor instance "randomTextAreaID" is already
attached to the provided element.
There are other suggestions that appear as "hacks" from 2012, but that is 6 years ago. Can't imagine that setting a placeholder for a text editor would be this difficult.
** EDIT **
So I got it to work like this:
var editor = CKEDITOR.instances['randomTextAreaID'];
if (editor) { editor.destroy(true); }
CKEDITOR.replace( 'randomTextAreaID', {
height: 20,
});
but still looks like trying to set a placeholder isn't working.
I've also downloaded the placeholder plugin and placed it here: views/assets/javascripts/ckeditor/plugins/placeholder and still no luck. No javascript loading errors, just simply not working.
A: If you wish to use placeholders, please add this plugin to your CKEditor build. Since the placeholder require plugins which also have couple of dependencies, I would recommend using online builder. Simply select your package (e.g. standard), add placeholder plugin and the builder will take care of dependencies. Next download the minified version.
Once you have that working you need to add place holder in instance configuration (config.js is a global configuration, while configuration in replace method is instance specific):
CKEDITOR.replace( 'randomTextAreaID', {
height: 20,
extraPlugins : 'placeholder'
});
Place holders can be inserted using placeholder dialog. They will also auto-change (e.g. your initial content) text like [[any text]] to placeholder. To use more technical terms - this text will be upcasted to placeholder widget.
Please also see the placeholder demo in action: https://sdk.ckeditor.com/samples/placeholder.html
A: ckeConfig = {
extraPlugins: 'placeholder'
};
---------------------------------------------------------------------
<ckeditor id="editor1" [config]="ckeConfig"
(namespaceLoaded)="onNamespaceLoaded($event)"
[(data)]="editorData">
</ckeditor>
----------------------------------------------------------------------------
public onNamespaceLoaded( event ) {
event.on('dialogDefinition', function(event) {
if ('placeholder' == event.data.name) {
var input = event.data.definition.getContents('info').get('name');
input.id= 'aps-placeholders',
input.type = 'select';
input.items = [ ['Company'], ['Email'], ['First Name'], ['Last Name'] , ['City'] , ['Province'] , ['Province']];
input.setup = function() {
this.setValue('Company');
};
}
});
}
Add this method in ts , it will work fine if anyone has the same issue with cdkplaceholder ,Above solution is for angular(2+)

Suddenly I am getting the following error:
SqlException: The INSERT permission was denied on the object '', database '', schema 'dbo'.
I checked my user which is db owner in the database. Add my user directly to the table itself.
I am still getting the error.
How can I view it in SQL Profiler which account executed the query?
This is a virtual machine and everything is installed using my account.
Edit:1
*
*The SQL Profiler is running inside the same machine where SQL server is install. It is a completely isolated environment. Everything runs inside the same machine.
*Everything is installed under one account and that is mine account. No other account is used.
*SQL Server Agent (MSSQLServer) is running under NT Service\SQLServeragent
*SQL Server : NT Service\MSSQLSERVER
*My account has sysadmin and db_owner rights on the database
*gave direct access to the tables as well, but still no luck
A: In terms of capturing the offending batch/query in SQL Profiler, I'd suspect that perhaps you aren't capturing the correct events? If an exception is being thrown, the only way you'd be able to see which actual SQL batch/statement caused the exception would be by including "starting" events (in addition to the more common captured "completed" events).
Running a trace with the following should allow you to see which procedure/statement is throwing the exception if you are capturing the correct events, those you'd want to capture would/could include:
*
*SQL:BatchStarting
*SQL:BatchCompleted
*SQL:StmtStarting
*SQL:StmtCompleted
*RPC:Starting
*RPC:Completed
*SP:Starting
*SP:Completed
*SP:StmtStarting
*SP:StmtCompleted
*Exception
You mentioned you're using EF, so you could likely safely ignore events 5 & 6, and also 7-9 if you're not actually executing a sproc. Be sure you capture all associated columns in the trace as well (should be the default if you are running a trace using the Profiler tool). The Exception class will include the actual error in your trace, which should allow you to see the immediate preceding statement within the same SPID that threw the exception. You must include the starting events in addition to the completed events as an exception that occurs will preclude the associated completed events from firing in the trace.

Edit One thing I have noticed is that if I change keyup to blur it will work fine. I need this to run on keyup though. It will also accept .25 by itself but not a number then decimal. For example 2.25.
$(document).on('keyup', '.Monday', findTotalMon);
function findTotalMon() {
var arr = document.getElementsByClassName('Monday');
var tot = 0;
for (var i = 0; i < arr.length; i++) {
if (parseFloat(arr[i].value)) {
var newValue;
newValue = (.25 * Math.round(4 * arr[i].value));
arr[i].value = newValue;
tot += parseFloat(newValue);
}
}
document.getElementById('totalHoursMon').value = tot;
if (tot === 0) {
document.getElementById('totalHoursMon').value = '';
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input class="form-control full-width Monday" name="monday" id="monday" type="number" step="any" /><br><br>
<input class="form-control full-width totalBox" name="total" id="totalHoursMon" type="text" readonly="readonly"/>
A: The issue lies in the use of keyup and the overwriting of your fields value with the newly parsed / rounded float.
After typing your decimal separator, the input is parsed and rounded and the separator disappears, because "1." or "1," is parsed to 1.
One way to solve this is to only overwrite your field when the rounded input is different than the original input.
$(document).on('keyup', '.Monday', findTotalMon);
function findTotalMon() {
var arr = document.getElementsByClassName('Monday');
var originalValue, newValue, tot = 0;
for (var i = 0; i < arr.length; i++) {
originalValue = arr[i].value;
if (parseFloat(originalValue)) {
newValue = (.25 * Math.round(4 * arr[i].value));
tot += parseFloat(newValue);
if (newValue != originalValue) {
// we're only overwriting input when the rounded value is different than the original
arr[i].value = newValue;
}
}
}
document.getElementById('totalHoursMon').value = tot;
if (tot === 0) {
document.getElementById('totalHoursMon').value = '';
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input class="form-control full-width Monday" name="monday" id="monday" type="number" step="any" /><br><br>
<input class="form-control full-width totalBox" name="total" id="totalHoursMon" type="text" readonly="readonly"/>
On a side note :
Using keyup and overwriting your user's input is really annoying. For instance, while testing, I realized you can't use backspace to correct your input. I know you said you had to use keyup, but I strongly advise you to use blur or keypress. For your user's sake :)

ex: i have selected the date as "Thu Feb 22 2018 00:00:00 GMT+0530 (India Standard Time)".this is the value i get when i log in console.
But when i tried to debug in C# the value is changed.

How to handle or work with the typescript date object when passing it to a API method and displaying it back
My typescript Model
export class Visitor {
public id: number;
public firstname: string;
public lastname: string;
public dob: Date;
public genderId: number;
public age: number;
}
and C# model
public class Visitor
{
public int Id { get; set; }
public string Lastname { get; set; }
public string Firstname { get; set; }
public int Age { get; set; }
public DateTime DOB { get; set; }
}
A: As long as you are passing a valid Date object you should be fine.
Your problem probably lies in your Culture settings in .NET side.
Can you please try doing this in your controller action:
var culture = new CultureInfo("gu-IN");
CultureInfo.DefaultThreadCurrentCulture = culture;
CultureInfo.DefaultThreadCurrentUICulture = culture;
Since you provide no code, this is merely a guess.
A: When you are printing in console, browser is printing the date in local timezone which is India in your case. When you are retrieving the value on server, C# is treating date in UTC. That is why you see a difference of 5.30 hours. India time is UTC + 5.30 Hours.
If you are storing the date value in UTC format on server side then convert the value of date object from client side to UTC using the libraries such as momentjs.
While retrieving the value from server, send the UTC value from server and convert it to local time zone using libraries such as momentjs. I think this strategy will work.

background_splash.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="@color/dark_blue"/>
<item android:top="100dp">
<bitmap
android:gravity="top"
android:src="@mipmap/img_logo"/>
</item>
</layer-list>
As you see, I place the logo with margin 100dp from the top. Then I try to do the same in my fragment layout:
fragment_start.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@mipmap/bg_create_account">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@mipmap/img_logo"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="100dp" />
</RelativeLayout>
But the logo in the layout appears lower than logo on the splash screen. I thought, the problem is in the default margin of Activity. But if I set:
<dimen name="activity_horizontal_margin">0dp</dimen>
<dimen name="activity_vertical_margin">0dp</dimen>
Nothing still happens. I always see the "jump" of logo from top to down about 10-20 dp. How can I avoid it?
EDIT: My activity xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"/>
</LinearLayout>
EDIT 2: I tried to pick up the distance manually and if I set <item android:top="125dp"> (or 126dp) and leave android:layout_marginTop="100dp" I see no "jump". It means the difference is 25 or 26 dp, but where are they?
EDIT 3: according to answer from Bryan the issue exists only in Android 4.4(API 19) and above. To avoid it I overrode styles.xml in folder values-19 with:
<item name="android:windowTranslucentStatus">true</item>
A: It seems drawable that you use for the splash screen does not take into account the size of the status bar, but the Activity does. This is the ~25dp difference you are observing, though this height of ~25dp is not guaranteed to be the same on all devices.
A: Maybe the problem is in the ActionBarSize, try add this to the SplashScreen :
Without AppCompat
android:paddingTop="?android:attr/actionBarSize"
With AppCompat
android:paddingTop="?attr/actionBarSize"
Or if you want, (although may be considered a bad practice), you can set a negative padding in the Activity Layout using data binding :
android:paddingTop="@{-1 * ?android:actionBarSize}"

Here's the code
url<-'http://myneta.info/uttarpradesh2017/index.php?action=summary&subAction=candidates_analyzed&sort=candidate#summary'
webpage<-read_html(url)
candidate_info<- html_nodes(webpage,xpath='//*[@id="main"]/div/div[2]/div[2]/table')
candidate_info<- html_table(candidate_info)
head(candidate_info)
But getting no output, suggest what I am doing wrong?
A: That site has some very broken HTML. But, it's workable.
I find it better to target nodes in a slightly less fragile way. The XPath below finds it by content of the table.
html_table() croaks (or took forever and I didn't want to wait) so I ended up building the table "manually".
library(rvest)
# helper to clean column names
mcga <- function(x) { make.unique(gsub("(^_|_$)", "", gsub("_+", "_", gsub("[[:punct:][:space:]]+", "_", tolower(x)))), sep = "_") }
pg <- read_html("http://myneta.info/uttarpradesh2017/index.php?action=summary&subAction=candidates_analyzed&sort=candidate#summary")
# target the table
tab <- html_node(pg, xpath=".//table[contains(thead, 'Liabilities')]")
# get the rows so we can target columns
rows <- html_nodes(tab, xpath=".//tr[td[not(@colspan)]]")
# make a data frame
do.call(
cbind.data.frame,
c(lapply(1:8, function(i) {
html_text(html_nodes(rows, xpath=sprintf(".//td[%s]", i)), trim=TRUE)
}), list(stringsAsFactors=FALSE))
) -> xdf
# make nicer names
xdf <- setNames(xdf, mcga(html_text(html_nodes(tab, "th")))) # get the header to get column names
str(xdf)
## 'data.frame': 4823 obs. of 8 variables:
## $ sno : chr "1" "2" "3" "4" ...
## $ candidate : chr "A Hasiv" "A Wahid" "Aan Shikhar Shrivastava" "Aaptab Urf Aftab" ...
## $ constituency : chr "ARYA NAGAR" "GAINSARI" "GOSHAINGANJ" "MUBARAKPUR" ...
## $ party : chr "BSP" "IND" "Satya Shikhar Party" "Islam Party Hind" ...
## $ criminal_case: chr "0" "0" "0" "0" ...
## $ education : chr "12th Pass" "10th Pass" "Graduate" "Illiterate" ...
## $ total_assets : chr "Rs 3,94,24,827 ~ 3 Crore+" "Rs 75,106 ~ 75 Thou+" "Rs 41,000 ~ 41 Thou+" "Rs 20,000 ~ 20 Thou+" ...

The code I used for that is
python3 manage.py makemigrations
I tried:
python3 manage.py makemigrations polls
and it shows
"App 'polls' could not be found. Is it in INSTALLED_APPS?"
Here is my INSTALLED_APPS of the 'settings.py' file

I know some people simply put 'polls', it doesn't work either
Here is my folder structure:

SELECT *
FROM obj
WHERE ObjectType = 'user'
AND ( ((( valueOne > 6.13661152336E-318 ) and ( valueTwo < 1.68611310981 )
The problem is obviously that ValueOne is too small and hence cannot be represented within normal 64bit machine precision. The problem is that I read these values from a file and I do not have control over what Input data I get. I would implement a rounding procedure to deal with this problem, but I am not sure which is the minimal (in absolute value) representable number in SQL Server 2012 Express.
Can anyone help me on the matter
A: Decimal and numeric:
Fixed precision and scale numbers. When maximum precision is used, valid values are from - 10^38 +1 through 10^38 - 1
float and real:
Float Range: - 1.79E+308 to -2.23E-308, 0 and 2.23E-308 to 1.79E+308
Real Range: - 3.40E + 38 to -1.18E - 38, 0 and 1.18E - 38 to 3.40E + 38
int, bigint, smallint, and tinyint:
bigint range: -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807)
int range: -2^31 (-2,147,483,648) to 2^31-1 (2,147,483,647)
smallint range: -2^15 (-32,768) to 2^15-1 (32,767)
tinyint range: 0 to 255
6.13661152336E-318 is outside the range representable in SQL Server as a native SQL Server supported type. You can try to use a CLR User defined type. You'll need a custom CLR library to manipulate such extreme values.

This works well along with a server-rendered MVC application but i can't get it to work with a SPA using hellojs.
I was fiddling with the urls to get the login-page from Identity Server displayed. The login-logic is running fine but i think any little piece is missing to propertly redirect to my client app with an access token.
This is the code i use to initialize hellojs:
const AuthorityUrl = 'http://localhost:5000';
hello.init({
'openidconnectdemo': {
oauth: {
version: '2',
auth: AuthorityUrl + '/Account/Login',
grant: AuthorityUrl + '/Grant'
},
scope_delim: ' '
}
});
hello.init({
openidconnectdemo: this.authConfig.clientId
});
And this is the login code
hello.login('openidconnectdemo', {
redirect_uri: this.authConfig.redirectUrl,
scope: `openid profile`,
response_type: 'token',
display: 'page',
});
In this code in AccountController, Identity Server tries to redirect to the application but this fails as the ReturnUrl is null:
if (Url.IsLocalUrl(model.ReturnUrl))
{
return Redirect(model.ReturnUrl);
}
else if (string.IsNullOrEmpty(model.ReturnUrl))
{
return Redirect("~/");
}
else
{
// user might have clicked on a malicious link - should be logged
throw new Exception("invalid return URL");
}
Do i have to modify Identity Server in order to get them work together or is there something missing on the client part?
Thanks for any advise!
A: I'd probably recommend using oidc-client-js as it is a full implementation of OIDC and should be much easier to get working.
That said, it looks like your first issue here is that the auth URL should point at the authorize endpoint and not the sign in UI - i.e. it should be /connect/authorize rather than /account/login.

This is my Controller Code:
public function courseDetails($id)
{
$courseByID = DB::table('courses')
->join('course_outlines','course_outlines.course_id','=','courses.id' )
->where('courses.id',$id)
->select('courses.*','course_outlines.title1','course_outlines.class1')
->first();
return view('frontEnd.pages.courseDetails',['courseByID'=>$courseByID]);
}
This is my View code:
<div class="card" >
<div class="card-body">
<h2 class="">Course Outline</h2>
<div class="outline_section">
<h4><span class="outline_header">{{$courseByID->title1}}</span></h4>
<ul>
<li>{{$courseByID->class1}}</li>
</ul>
</div>
</div>
</div>
I want to show like this but using just 1 row ..
dd($courseByID) result :

"""
}
A: You can do like this :
<div class="card" >
<div class="card-body">
<h2 class="">Course Outline</h2>
<div class="outline_section">
<h4><span class="outline_header">{{$courseByID->title1}}</span></h4>
<ul>
@foreach(str_replace(['""','*'],['',''], explode(",",$courseByID->class1)) as $key => $val)
<li>{{ $val }}</li>
@endforeach
</ul>
</div>
</div>
</div>

string binary = "10011101";
MessageBox.Show(Convert.ToInt32(binary, 2).ToString("X"));
I will get the output as 9D. This is the simplest code which I can write in CSharp for converting Binary to Hexadecimal.
Is there any such way to do the same in SQL also(using some inbuilt function if any is available). Is it fn_varbintohexstr?
Is there any bitwise operation which will help to do the same conversion.
Thanks
A: select master.sys.fn_varbintohexstr(@binvalue)
Should do the trick.
A: I'm not aware of a built-in function which will convert a stream of bits into hex.
One solution would be to write a CLR function to carry out the conversion using the .Net code you have above.
Below is a T-SQL implementation, which splits the string into individual characters and then converts them to hex. If you have your own numbers table, the CTE can be discarded:
DECLARE @vch_string VARCHAR(MAX)
DECLARE @chr_delim CHAR(1)
SET @chr_delim = ','
SET @vch_string = '10011101'
-- replace nums_cte with a join to a numbers table if you have one
-- since it will be far more efficient.
;WITH nums_cte
AS
(
SELECT 1 AS n
UNION ALL
SELECT n+1 FROM nums_cte
WHERE n < LEN(@vch_string)
)
SELECT CAST(SUM(CAST(SUBSTRING(s,n,1) AS INT) * POWER(2,n -1)) AS VARBINARY(1)) AS hexvalue
FROM (SELECT REVERSE(@vch_string) AS s) AS D
JOIN nums_cte
ON n <= LEN(s)
OPTION (MAXRECURSION 0);

I found some extension library for Apache-Beam that does it:
But I can't find a way to save the sketch itself to BigQuery. to be able to use it later with merge function and other functions by some time sliding: see this link
my code:
.apply("hll-count", Combine.perKey(ApproximateDistinct.ApproximateDistinctFn
.create(StringUtf8Coder.of())))
.apply("reify-windows", Reify.windows())
.apply("to-table-row", ParDo.of(new DoFn< ValueInSingleWindow<KV<GroupByData,HyperLogLogPlus>>, TableRow>() {
@ProcessElement
public void processElement(ProcessContext processContext) {
ValueInSingleWindow<KV<GroupByData,HyperLogLogPlus>> windowed = processContext.element();
KV<GroupByData, HyperLogLogPlus> keyData = windowed.getValue();
GroupByData key = keyData.getKey();
HyperLogLogPlus hyperLogLogPlus = keyData.getValue();
if (key != null) {
TableRow tableRow = new TableRow();
tableRow.set("country_code",key.countryCode);
tableRow.set("event", key.event);
tableRow.set("profile", key.profile);
tableRow.set("occurrences", hyperLogLogPlus.cardinality());
I just found how to do hyperLogLogPlus.cardinality() but how can write the buffer itself, in way I can run on it later merge function, in BiGQuery.
Using hyperLogLogPlus.getBytes also didn't work for merge.
A: Currently this functionality is not supported by Apache Beam, but there are people working on it.
To be specific:
The extension library in Apache Beam you mentioned depends on this HyperLogLog implementation. The sketches produced by this library is not consistent with the sketches computed by Google Cloud BigQuery. So it wouldn't make sense to merge sketches in BigQuery.
A: Since this question was first asked in 2019 April, a BigQuery-compatible implementation of HLL sketch has been released, as noted in this GCP blog post, Using HLL++ to speed up count-distinct in massive datasets.
The post has illustrative code snippets showing how to save the HLL sketches to BigQuery as well as to GCS files.
Quoting the relevant parts of the post:
[The Google implementation of HyperLogLog] was added to BigQuery in 2017 and has recently been open sourced and made directly available in Apache Beam as of version 2.16. That means it’s available for use in Cloud Dataflow ...
Note: As of version 2.16, there are several implementations of approximate count algorithms. We recommend the use of HllCount.java, especially if you need sketches and/or need compatibility with Google Cloud BigQuery.
From section 3 of the post, "Storing the sketches in BigQuery":
BigQuery supports HLL++ via the HLL_COUNT functions, and BigQuery’s sketches are fully compatible with Beam’s, so it’s easy to interoperate with sketch objects across both systems.
In the example below we will:
1. Pre-aggregate data into sketches in Beam;
2. Store the sketches in BigQuery as byte[] columns along with some metadata about the time interval;
3. Run a rollup query in BigQuery, which can extract the results at interactive speed, thanks to the sketches that were pre-computed in Beam.

It gives an error "in" Token comma needed..? What else I need to do bring total rows?
A: You can use several steps to create several helper columns with intermediate results of conditional sums. Then you can create a new column, sum up all the intermediate results and the delete the helper columns with the intermediate results.
Keep in mind that unlike Excel, the calculations in Power Query always return constants and you can then delete calculated columns you no longer need. So,
*
*Create helper column 1 with complicated IF and Sum scenario
*Create helper column 2 with complicated IF and Sum scenario
*Create total column to add column 1 + column 2
*Delete helper columns and keep only the total column
A: That gives me exact result what I was looking for, but it is with DAX formula in PowerPivot:
=SUMX(FILTER('TableName',[ColName] = 1),'TableName'[ColName2])
So would be glad to convert it to Power-Query formula

i want to get data but it prints null
A: Change your code to this :
var sheetController = showBottomSheet(
context: context, builder: (context) => displayBottomSheet(number));
sheetController.closed.then((value) async {
await print(value);

$types = DB::table('cemetery_charge_types')
->join('payment_details', 'invoices.id', '=', 'payment_details.payable_id')
->join('invoices', 'cemetery_charge_types.id', '=', 'invoices.charge_type_id')
->select('cemetery_charge_types.*', DB::raw('SUM(payment_details.amount) as amount'),'invoices.*')
->whereIn('payment_details.payment_id', $payments->pluck('id'))
->get();
I have made sure all of the column names are correct, along with their tables, but I get the following error: Column not found: 1054 Unknown column 'invoices.id' in 'on clause'....
I have a table with charge types, which can have multiple invoices, who in turn can have multiple payment_details.
A: You need to change the order of your joins like this:
$types = DB::table('cemetery_charge_types')
->join('invoices', 'cemetery_charge_types.id', '=', 'invoices.charge_type_id')
->join('payment_details', 'invoices.id', '=', 'payment_details.payable_id')
->select('cemetery_charge_types.*', DB::raw('SUM(payment_details.amount) as amount'),'invoices.*')
->whereIn('payment_details.payment_id', $payments->pluck('id'))
->get();

I want to build a timeline of received and sent money of all users starting from a given date.
In case of startDate is "2019-02-01T00:00:00.000+0000", the ouput of my request should be like this:
[
{
"userId":"user123",
"name":"John",
"card":{
"amount":1000.0,
"sentMoneyList":[
{
"creationDate":"2019-08-07T00:00:00.000+0000",
"shopId":"merchant1",
"loyaltyPoint":200,
"amount":250
}
]
}
},
{
"userId":"user123",
"name":"John",
"card":{
"amount":1000.0,
"receivedMoneyList":[
{
"creationDate":"2019-09-07T00:00:00.000+0000",
"amount":40
}
]
}
},
{
"userId":"user123",
"name":"John",
"card":{
"amount":1000.0,
"receivedMoneyList":[
{
"creationDate":"2019-03-07T00:00:00.000+0000",
"amount":500
}
]
}
}
]
Here the java code that tries to get this result:
Criteria criteriaClient = new Criteria();
MatchOperation matchOperation = match(criteriaClient.orOperator(
Criteria.where("card.sentMoneyList.creationDate").gte(startDate),
Criteria.where("card.receivedMoneyList.creationDate").gte(startDate)));
UnwindOperation unwindSent = Aggregation.unwind("card.sentMoneyList");
UnwindOperation unwindReceived = Aggregation.unwind("card.receivedMoneyList");
Aggregation aggregation = Aggregation.newAggregation(unwindSent, unwindReceived, matchOperation);
List<UserDTO> result = mongoTemplate.aggregate(
aggregation, "users", UserDTO.class).getMappedResults();
It gives an empty List. what is missing in the query in order to get the result above ?
Thanks
A: You can achieve the expected output with $facet which helps you to categorize the incoming data. Here I have get sentMoneyList array in sentMoney array and receivedMoneyList array in receivedMoney. Then aggregate whatever that gives you the output.
public List<Object> test() {
Aggregation aggregation = Aggregation.newAggregation(
facet(
p -> new Document("$project",
new Document("card.receivedMoneyList", 0)
),
a -> new Document("$addFields",
new Document("card.sentMoneyList",
new Document("$filter",
new Document("input", "$card.sentMoneyList")
.append("cond",
new Document("$gte", Arrays.asList("$$this.creationDate", "2019-02-01T00:00:00.000+0000"))
)
)
)
),
unwind("$card.sentMoneyList")
).as("sentMoney").and(
p -> new Document("$project",
new Document("card.sentMoneyList", 0)
),
a -> new Document("$addFields",
new Document("card.receivedMoney",
new Document("$filter",
new Document("input", "$card.receivedMoney")
.append("cond",
new Document("$gte", Arrays.asList("$$this.creationDate", "2019-02-01T00:00:00.000+0000"))
)
)
)
),
unwind("$card.receivedMoney")
).as("receivedMoney"),
p -> new Document("$project",
new Document("combined",
new Document("$concatArrays", Arrays.asList("$sentMoney", "$receivedMoney"))
)
),
unwind("$combined"),
replaceRoot("combined")
).withOptions(AggregationOptions.builder().allowDiskUse(Boolean.TRUE).build());
return mongoTemplate.aggregate(aggregation, mongoTemplate.getCollectionName(Users.class), Object.class).getMappedResults();
}
First I request you to use Object.class to get the aggregated result and return as a List<Object>. If that works fine, then you can convert this model to UserDTO.class which should be structured same as output.
You have added a target collection users which is not a good practice. So use mongoTemplate.getCollectionName(YOUR_TARGET_COLLECTION.class)
Not : I've not tried this code, but this is written based on working Mongo playground

http://geoss.compusult.net/wes/serviceManagerCSW/csw?request=GetCapabilities&service=CSW
How would i create the proxy classes for the service?
More information HERE.
EDIT #1:
The hosting service above is implementing an OGC standard (CSW). The schemas for this standard are hosted HERE. And they have some WSDLs HERE. If i was to place the URL to one of those WSDL into visual studio's "add reference/service" i get a list of web operations and will generate a reference. However, that will not work because it does not know about the true hosting provider. So i'm not quite sure what to do.
Edit #2:
This is what it generated:
EDIT #3:
Following John Saunders's comment to check for erors, i got the following:
Custom tool error: Failed to generate
code for the service reference
'ServiceReference1'. Please check
other error and warning messages for
details. D:\temp\WebApplication2\WebApplication2\Service
References\ServiceReference1\Reference.svcmap 1 1 WebApplication2
So i checked the warnings and i saw a few warnings similar to this:
Warning 1 Custom tool warning: Cannot
import wsdl:portType Detail: An
exception was thrown while running a
WSDL import extension:
System.ServiceModel.Description.XmlSerializerMessageContractImporter
Error: Schema with target namespace
'http://www.opengis.net/cat/csw/2.0.2'
could not be found. XPath to Error
Source:
//wsdl:definitions[@targetNamespace='http://www.opengis.net/cat/csw/2.0.2/requests']/wsdl:portType[@name='csw'] D:\temp\WebApplication2\WebApplication2\Service
References\ServiceReference1\Reference.svcmap 1 1 WebApplication2
And these are the same types of warnings i've been getting when doing anything with with these schemas in .NET. Aren't schemas supposed to work with any language? Here are some example of my heart ache with .NET and these schemas:
HERE
HERE
HERE
So i'm not sure whether to blame the schemas or .NET for not being able to deal with such large schemas.
Event though Marc and Basiclife both provided answers that would have normally worked on "normal" schemas, John is getting the answer because he helped me troubleshoot it when i did not think it was a troubleshooting issue, but rather something i was missing. I should have known with these schemas though i thought creating the client wouldn't be as much of a big deal.
A: Right-click on your project, and go to Add Service Reference. Click Advanced at the bottom-left, then Add Web Reference at the bottom left again.
When you put in the URL, it will look up the available services, which you can select and give a name for within your project.
Edit:
Once you have the wsdl imported, you can change its base address via your app config.
Edit 2:
I am also used to WCF services :-) To change the URL, right-click on your reference, go to Properties, and change the Web Reference URL to whatever you need.
Edit 3:
When I add the reference, the following warning message appears in my Error List:
Warning 1 Custom tool warning: DiscoCodeGenerator unable to initialize code generator. No code generated. s:\dev\Sandbox\Sandbox\Web References\net.opengis.schemas\Reference.map
This is why Reference.cs is empty.
A: Right-click the project, select Add Service Reference. Enter the URL provided...
EDIT:
Add the reference to the WSDL. This is what VS needs to create the proxies.
Once the proxies have been created, you can edit the URL it actually uses to access the service in the web.config / app.config file for your application
A: Use the actual WSDLs to generate the service reference. Then, when you open the proxy class, use the constructor overload that includes an EndpointAddress. That will include the URL of the actual service.
The URL in the WSDL is only a hint.

def run
@entries.keep_if { |i| valid_entry?(i) }.each do |e|
begin
unique_id = get_uniqueid e
cdr_record = Cdr.find_by_uniqueid(unique_id).first
recording = cdr_record.nil? ? NullAsteriskRecording.new : AsteriskRecording.new(cdr_record, e)
recording.set_attributes
recording.import
rescue Exception => e
fail_status
end
end
end
fail_status is a private method that updates the instance variable to :failed. Through breaking some other things, I've basically verified this code works, but I want a test in place as well. Currently, I've got the following:
context "in which an exception is thrown" do
before do
@recording = double("asterisk_recording")
@recording.stub(:import).and_raise("error")
end
it "should set #status to :failed" do
# pending "Update instance variable in rescue block(s) of #run"
subject.run
subject.status.should eq :failed
end
end
But the test always fails. The rescue block is never evaluated (I checked with a puts statement that would be evaluated when I hardcoded in a raise statement). Am I using the double feature wrong, here? Or am I doing myself in by stubbing out an exception, so the rescue block never gets run?
A: You set up @recording in your before block, but the code you have posted for your run method will not use that @recording instance and therefore the call to recording.import in the run method will not raise an exception.
In your run method, recording can either end up being an instance of NullAsteriskRecording or AsteriskRecording. If you know that it is going to be an AsteriskRecording as your current test implies, one approach would be to change your before block to the following:
before do
AsteriskRecording.any_instance.stub(:import).and_raise("error")
end
