for example
var abb =dat.Abbrivation ;
A: You don't need jQuery. Just grab the object.
var abb = dat[0].Abbrivation;
jQuery is unfortunately a crutch for newer programmers. It is not necessarily good practice to turn everything into a jQuery function, especially if it isn't necessary at all.
update
dat, being an array, needs to have its first instance selected, which then has the Abbrivation property.

D:\My First Directory
D:\My Second Directory
when I am pass this two argument in console program in C#
like this :
Program.exe D:\My First Directory D:\My Second Directory
I access this this of output.
args[0] : D:\My
args[1] : First
args[2] : Directory
args[3] : D:\My
args[4] : Second
args[5] : Directory
I want to this type of output :
args[0] : D:\My First Directory
args[1] : D:\My Second Directory
A: The only way to do it is to pass the arguments inside double quotes, like this:
Program.exe "D:\My First Directory" "D:\My Second Directory"
There is no other simple way.
Operating system just works like that. One string is one argument.
You could do some wise mechanism though.
I wouldn't do it, I would just put those directories in double quotes.
But if I for some reason REALLY, REALLY had to do it, I'd do it like that:
*
*get all the arguments into one string
*magically split this string into list (array) of strings, using regular expressions (looking for string like: "D:\", of course as a regular expression).
But it could only work if you can only have directories in arguments and nothing else.

There is an API call to verify receipts, but I cannot find one to cancel. I looked at apple developer doc but could not find it.
Is there such an API? If not, what is the correct way to do this?
A: Unfortunately, there is no API to cancel a subscription. User have to do it themselves in the manage subscription screen.
For their convenience, you could provide a link to that screen in your app or via an email.

*pickup
*arrived
*in_route_to_destination
.
.
.
and so on
Since the database views dont propogate default values to the model, i am defining the values as follows
def pickup
self[:pickup] || true
end
def arrived
self[:arrived] || true
end
def delivery
self[:delivery] || true
end
There are 11 statuses and if i follow this way, i need to define 11 methods of the format
def status_name
self[:status_name] || true
end
Is there a way to optimise this?
A: I'm not sure it's the best design to have separate columns for each status as opposed to a generic status column but I don't know your full requirements so maybe that works best.
You can define them dynamically, though.
STATUS_COLUMNS = %i(pickup arrived in_route_to_destination delivery)
STATUS_COLUMNS.each do |method|
define_method method do
self[method] || true
end
end

I did this but the problem is count value same for each row.so I want when user increase and decrease the count of row 0 the count 1
after that when user come to second-row count should start from 0 not be count 1
Please help me to resolve this issues??.I want to increase and decrease the count of each row. so According to count ,prize should be increased Row 1 Count 1,prize 100 =100 Row 2 Count 2,prize 200= 400 But In my case count always showing last count value.for each row count value should be start from 1
A: I don't know what you tried so far, but you can do something like this.
holder.ivMinus.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int quantity = Integer.parseInt(holder.tvItemQuantity.getText().toString());
if (quantity > 0) {
quantity = quantity - 1;
storeItem.setItemQuantity("" + quantity);
holder.tvItemQuantity.setText(storeItem.getItemQuantity());
totoal = totoal * quantity;
Gtotoal = Gtotoal - Integer.parseInt(storeItem.getItemPrice());
;
settotal.setTotal(" \u20B9 " + Gtotoal);
} else {
}
}
});
holder.ivPlus.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int quantity = Integer.parseInt(holder.tvItemQuantity.getText().toString());
quantity = quantity + 1;
storeItem.setItemQuantity("" + quantity);
holder.tvItemQuantity.setText(storeItem.getItemQuantity());
Gtotoal = Gtotoal + Integer.parseInt(storeItem.getItemPrice());
settotal.setTotal(" \u20B9 "+ Gtotoal);
}

$('.class').parent().hover(
function() {
$({ value: $(this).val() }).animate( .... );
...
}, function() {
$({ value: $(this).val() }).animate( .... );
...
});
Unfortunately due to a plugin i use for creating a slider i have to use the .parent() selector, so i can not use ..
$('.parent') -> $('.class', this)
.. what i think it would solve it.
I have three elements with the ".class"-class and they are all three animated whenever i hover one of them.
further explanation:
The html is only one thing:
<input type="text" value="0" class="class" />
The Plugin creates a canvas above the input and the input is used as the value for the animated bar. It also creates a div wrapping around this two elements. Like so :
<div>
<canvas>
<input ... >
</div>
I'm sure i can find a easy solution by using id's and writing it multiple times in the code with the id's as selector, but i hope for a more elegant way to solve this.
Here the JSFiddle
A: As long as you know that the <canvas> tag will always be created, why not just use the <canvas> tag as the selector to provide context?
$('canvas').hover(
function() {
var that = $(this);
$({ value: $(this).next() }).animate(
...
progress: function() {
that.next().val(Math.round(this.value)).trigger('change');
}
);
}, function() {
var that = $(this);
$({ value: $(this).next().val() }).animate(
...
progress: function() {
that.next().val(Math.round(this.value)).trigger('change');
}
);
});
NEW Working Fiddle
A: Maybe try wrapping it in an event listener instead:
$(function(){
$('.class').on('hover',function(){
$({value:$(this).parent().val()}).animate( ...)
})
});

So if i comment ( like in the code) the loading of the script sketch.js i cant go to my sketch.js where i load the maze and the game background… But i have tried many things ( document.write, innerHTML, etc…) i just want to load sketch when i click on Button startGame ( so the function startGame would be launched)… If i delete the comments, and use the script, it works ok, but i want to control when to launch sketch.js ( when i press the button Start Game and not before)
If you know of anything easier would be nice…
Also i have another doubt… i want to print some text like scores, lives and time remaining… do you use another canvas to put text on it ( perhaps in a side of the screen or in the bottom), o in the same canvas you make room to have enough space to write ??
Thanks
A: You could store whether the game is started in a variable at the top of your sketch:
var started = false;
function draw(){
if(started){
// draw your game
}
}
function mousePressed(){
started = true;
}
You could set started equal to true when you press the button.
Or you could look into instance mode which allows you to load a sketch on the fly. You can read more about instance mode here.
Also i have another doubt… i want to print some text like scores, lives and time remaining… do you use another canvas to put text on it ( perhaps in a side of the screen or in the bottom), o in the same canvas you make room to have enough space to write ??
Either approach is fine. It's completely up to you. You could also modify the webpage and print the score there. The P5.dom library could come in handy for this.

Time::DATE_FORMATS[:db_usec] = '%Y-%m-%d %H:%M:%S.%6N'
But with this format the time is formated with local time zone.
I have to change the time in UTC first.
Post.created_at.utc.to_s(:db_usec)
How can I write a DATE_FORMATS like :db that formats the time in UTC?
A: You can easily change it by referring to the Rails api link.
Time::DATE_FORMATS[:db_usec] = ->(time) { time.utc.strftime('%Y-%m-%d %H:%M:%S.%6N') }

*I have defined the classes as below.
*I have used dagger with Retrofit here
What I am trying to do::
I am trying to catch the OfflineException in the request below how to catch it in Main Activity properly.
RequestInterceptor.java
public class RequestInterceptor implements Interceptor {
ConnectivityManager connectivityManager;
Application mApplication;
@Inject
public RequestInterceptor(Application mApplication) {
this.mApplication = mApplication;
connectivityManager = (ConnectivityManager) mApplication.getSystemService(Context.CONNECTIVITY_SERVICE);
}
@Override
public Response intercept(Chain chain) throws IOException {
if (isConnected()) {
throw new OfflineException();
}
Request.Builder r = chain.request().newBuilder();
return chain.proceed(r.build());
}
protected boolean isConnected() {
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
return networkInfo != null && networkInfo.isConnectedOrConnecting();
}
public class OfflineException extends IOException {
@Override
public String getMessage() {
return mApplication.getResources().getString(R.string.app_no_connectivity);
}
}
}
NetModule.java
import android.app.Application;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import com.google.gson.FieldNamingPolicy;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import java.util.concurrent.TimeUnit;
import javax.inject.Singleton;
import commons.LinksAndKeys;
import dagger.Module;
import dagger.Provides;
import okhttp3.Cache;
import okhttp3.OkHttpClient;
import retrofitDagger.retrofitUtils.RequestInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
@Module
public class NetModule {
String mBaseUrl;
Application mApplication;
// Constructor needs one parameter to instantiate.
public NetModule(String baseUrl, Application application) {
this.mBaseUrl = baseUrl;
this.mApplication = application;
}
// Dagger will only look for methods annotated with @Provides
@Provides
@Singleton
// Application reference must come from AppModule.class
SharedPreferences providesSharedPreferences(Application application) {
return PreferenceManager.getDefaultSharedPreferences(application);
}
@Provides
@Singleton
Application providesApplication() {
return mApplication;
}
@Provides
@Singleton
Cache provideOkHttpCache(Application application) {
int cacheSize = 10 * 1024 * 1024; // 10 MiB
Cache cache = new Cache(application.getCacheDir(), cacheSize);
return cache;
}
@Provides
@Singleton
Gson provideGson() {
GsonBuilder gsonBuilder = new GsonBuilder();

return gsonBuilder.create();
}
@Provides

Retrofit retrofit = new Retrofit.Builder()

}
}
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Inject
Retrofit retrofit;
TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
((App) getApplication()).getNetComponent().inject(this);
//Create textview and findViewByID
textView = (TextView) findViewById(R.id.textview_post);

}
@Override
public void onFailure(Call<List<Post>> call, Throwable t) {
//Set the error to the textview
textView.setText(t.toString());
}
});
}
}
A: As I know, there is no internet connection the RetrofitError contains a ConnectionException as the cause.
public class RetrofitErrorHandler implements ErrorHandler {
@Override
public Throwable handleError(RetrofitError cause) {
if (cause.isNetworkError()) {
if (cause.getCause() instanceof SocketTimeoutException) {
/* your code here*/
return new MyConnectionTimeoutException();
} else {
/* your code here*/
return new MyNoConnectionException();
}
} else {
//Do whatever you want to do if there is not a network error.
}
}
}
Or you can create a custom Retrofit client that checks for connectivity before executing a request and throws an exception.
public class ConnectivityCheck implements Client {
Logger log = LoggerFactory.getLogger(ConnectivityCheck.class);
public ConnectivityCheck (Client wrappedClient, NetworkConnectivityManager ncm) {
this.wrappedClient = wrappedClient;
this.ncm = ncm;
}
Client wrappedClient;
private NetworkConnectivityManager ncm;
@Override
public Response execute(Request request) throws IOException {
if (!ncm.isConnected()) {
log.debug("No connectivity %s ", request);
throw new NoConnectivityException("No connectivity");
}
return wrappedClient.execute(request);
}
}
and then use it when configuring RestAdapter
RestAdapter.Builder().setEndpoint(serverHost)
.setClient(new ConnectivityCheck(new OkHttpClient(), ...))
A: As far as I know, I don't think Retrofit supports 'connectivity checking in call time' and I don't think that is exactly what you want.
Try to check connectivity before your call, for example,
private void sendData() {
if( isConnected ) {
switch(call) {
case "userSignIn":
Call !
break;
...
}
}
Maybe you can check this solution too

A: The problem is that you generate id for your ColorBall and then try to use this id as an index of colorballs array:
private static int count = 1;
public ColorBall(Context context, Bitmap drawable) {
...
id=count;
count++;
}
and:
protected void onDraw(Canvas canvas) {
...
case MotionEvent.ACTION_MOVE: // touch drag with the ball
// move the balls the same as the finger
if (balID > 0) {
colorballs[balID-1].setX(X-25);
colorballs[balID-1].setY(Y-25);
}
break;
...
}
Which evidently is wrong. If it is id of the ColorBall that you want to refer ColorBall objects by, then consider using other types of collections to hold a list of ColorBall objects, i.e. HashMap<Integer, ColorBall>, otherwise use the index of element within the array to refer to certain ColorBall object.

/usr/share/vagrant/gems/gems/vagrant-2.1.2/lib/vagrant/util/safe_exec.rb:39:
in `exec': : Permission denied - /home/username/bin/sshPermission denied - /home/username/bin/ssh ( (Errno::EACCESErrno::EACCES)
The doc says: Vagrant will attempt to use the local SSH client installed on the host machine. However, which ssh correctly results in: /usr/bin/ssh. So why vagrant doesn't use it ?
The directory! /home/username/bin/ssh was included in the PATH env when the box was created and vagrant seems to have stored this information somewhere. Removing the directory from PATH didn't help. Only when I rename or remove the directory vagrant ssh does work.
Can anyone tell me where vagrant stored the wrong info ?
Edit: The Vagrantfile is nearly empty, only config.vm.box contained...
A: Guess I found the reason - seems to be a bug or strange behavior of the vagrant version 2.1.2 that I use:
I still had directory /home/username/bin in the PATH env. Vagrant seems to list all entries in all directories included in PATH to look for ssh and finds subdirectory /home/username/bin/ssh not realizing that this is a directory ...
After removing /home/username/bin the command vagrant ssh works as expected. So unless vagrant is improved I have to permanently rename my /home/username/bin/ssh directory ...

Error: could not find function "tokens".
But I can use, for example, "tokenize".
My code is:
train.tokens <- tokens(train$Text, what = "word", remove_numbers = TRUE,
remove_punct = TRUE,remove_symbols = TRUE, remove_hyphens = TRUE).
As a side note, when I try to automatically update the quanteda package, it says that I have the 0.9.8.3 version and that the newest available is 0.9.8.5. After it gets updated, nothing happens.
Thank you!
A: You need to make sure you have a current version of quanteda and the packages that it imports. Then this will work fine:
> quanteda::tokens("This is a test")
tokens from 1 document.
text1 :
[1] "This" "is" "a" "test"
> packageVersion("quanteda")

Is there a way to trigger an RDP or some GUI style user session to become active in a headless manner? If not, then is there a different way to execute my application, where the interactive GUI is available with SSH or other means of headless connection when there is no active user signed in?
The Windows VMs have OpenSSH server running for connections.
A: This question actually solved the other half of the puzzle for me, namely how to get SSH connections to use the interactive session. Here's how to keep an active interactive session open at all times. Note that depending on your use case you might explicitly need a multi-session windows installation, which is a different VM image in Azure for example.
*
*Have the user you want these commands to run in log on automatically when windows boots. https://learn.microsoft.com/en-us/troubleshoot/windows-server/user-profiles-and-logon/turn-on-automatic-logon
*Create a .bat file with the following contents somewhere (for me it's just on C:) tscon 1 /dest:console
*In task scheduler, create a task that runs this bat file whenever a remote user disconnects.
Point 2-3 are not necessary if you never RDP into the autologon user. Whenever you RDP to this user, the console session moves from the autologon session to your RDP session, and this script just reattaches the console session back when you disconnect. This way, that user always has the console attached and thus has GUI available.

RUN sudo apk add --update --no-cache openrc
RUN sudo rc-update add nfsmount
RUN sudo mount -t nfs nfs.local:FILE_SHARE /mnt
A: Allowing a container to perform a filesystem mount would be a security vulnerability, allowing a container escape to the host.
You cannot do this at build time in the Dockerfile. Instead you should configure the container with a volume mount. Support for this was added earlier this year.

ROOT > DOMAIN ROOT FOLDER > PHP MKDIR
ROOT > IMAGE FOLDER > MKDIR HERE
I need the php in the 'domain root folder' to create a directory within the 'image folder'. Any help?
A: You can usually do something like this:
mkdir('../images/newfolder');
You may have to add more ../../ on to the front of this, depending on where you are running the script from exactly. Each ../ moves you up another level, so it seems like just one would work here given your example, but you have to be sure you are where you think you are.
A: You could also use absolute path in your php-script.
mkdir('/root/images/new_folder');
Make sure that your web-server has permissions for writing to specific folder.
A: I usally work from the directory my current script is located in and maneuver my way to the desired location from there. Works fine as long as you don't move you script. In addition, it will be easier to keep track of where everything is relative to the script.
You can get the current path with:
$path = dirname(__FILE__);
Then appending ../ to go deeper etc.

My question is as follows:
I have "images", all of the same dimensions, which in some sense correspond to different phases of a target image. And I'd like to rebuild that full-blown image with tf functionality.
This turns out to be much less simple than I originally expected and I'd be very grateful for any help!
A more detailed exposition follows:
In numpy, one easily interleaves images via simple assignment -
import numpy as np
im = np.random.random((1, 8, 8, 2))
phased_im_01 = im[:, ::2, 1::2, :]
phased_im_00 = im[:, ::2, ::2, :]
phased_im_10 = im[:, 1::2, ::2, :]
phased_im_11 = im[:, 1::2, 1::2, :]
rebuild_im = np.zeros((1, 8, 8, 2))
rebuild_im[:, ::2, ::2, :] = phased_im_00
rebuild_im[:, ::2, 1::2, :] = phased_im_01
rebuild_im[:, 1::2, ::2, :] = phased_im_10
rebuild_im[:, 1::2, 1::2, :] = phased_im_11
print(np.all(rebuild_im == im))
But as known, assignment is a no-go in tf, and one usually uses things like tf.concat coupled with tf.reshape (for very simple cases) or tf.scatter_nd (for more complicated cases). I was unsuccessful in implementing the equivalent of the above numpy-functionality using any of the many things I tried (like permuting the tensor to have the width dimension first, trying to scatter_nd, and permuting back, a method I've successfully used before for other problems), or any solution on SO (like stacking and reshaping oneself to death).
Just to be clear, my actual use-case has an unknown batch-size, thousands of channels, and 4 phases in each image dimension. But I just need a working solution for the simple toy example above; generalization is on me ;-)
Thanks to any helpers out there, (and sorry I can only describe my efforts and not show them. They're just a mess of unsuccessful mistakes degrading into horrible trial-and-error code snippets until giving up and coming here for some help anyway, so no major loss).
Clarifications can be added on demand.
A: To reproduce the numpy example in TensorFlow, please try depth_to_space:
import tensorflow as tf
im = tf.random_normal((1, 8, 8, 2))
phased_im_01 = im[:, ::2, 1::2, :]
phased_im_00 = im[:, ::2, ::2, :]
phased_im_10 = im[:, 1::2, ::2, :]
phased_im_11 = im[:, 1::2, 1::2, :]
phases = tf.concat(
(phased_im_00, phased_im_01, phased_im_10, phased_im_11), axis=3)
rebuild_im = tf.nn.depth_to_space(phases, block_size=2, data_format='NHWC')
dif = tf.reduce_sum(rebuild_im - im) # 0.0
As kindly suggested by ShlomiF, the more general example is:
import numpy as np
import tensorflow as tf
tf.enable_eager_execution()
num_of_channels = 20
h = w = 256
num_of_phases = 4
im = np.random.random((1, h, w, num_of_channels))
phase_ims = []
for i in range(num_of_phases):
for j in range(num_of_phases):
phase_ims.append(im[:, i::num_of_phases, j::num_of_phases, :])
all_phases = tf.concat(phase_ims, axis=3)
rebuild_im = tf.depth_to_space(all_phases, block_size=num_of_phases, data_format='NHWC')
diff = tf.reduce_sum(rebuild_im - im)
print(np.asarray(diff)) # --> 0.0
As far as I know, the idea of depth_to_space, or periodic shuffling, came from this paper. You may find more details and visualization there.

import math
import random
random.seed()
n = 10000
for i in range(n):
x = random.random()
y = random.random()
z = (x,y)
if x**2+y**2 <= 1:
print z
else:
del z
So far, I am able to generate all of the points I need, but what I would like to get is the number of points that are produced when running the script for use in a later calculation. I'm not looking for incredibly precise results, just a good enough estimate. Any suggestions would be greatly appreciated.
A: Not sure if this is what you're looking for, but you can run enumerate on range and get the position in your iteration:
In [1]: for index, i in enumerate(xrange(10, 15)):
...: print index + 1, i
...:
...:
1 10
2 11
3 12
4 13
5 14
In this case, index + 1 would represent the current point being created (index itself would be the total number of points created at the beginning of a given iteration). Also, if you are using Python 2.x, xrange is generally better for these sorts of iterations as it does not load the entire list into memory but rather accesses it on an as-needed basis.
A: If you're doing any kind of heavy duty numerical calculation, considering learning numpy. Your problem is essentially a one-linear with a numpy setup:
import numpy as np
N = 10000
pts = np.random.random((N,2))
# Select the points according to your condition
idx = (pts**2).sum(axis=1) < 1.0
print pts[idx], idx.sum()
Giving:
[[ 0.61255615 0.44319463]
[ 0.48214768 0.69960483]
[ 0.04735956 0.18509277]
...,
[ 0.37543094 0.2858077 ]
[ 0.43304577 0.45903071]
[ 0.30838206 0.45977162]], 7854
The last number is count of the number of events that counted, i.e. the count of the points whose radius is less than one.
A: Just add hits variable before the loop, initialize it to 0 and inside your if statement increment hits by one.
Finally you can calculate PI value using hits and n.
import math
import random
random.seed()
n = 10000
hits = 0 # initialize hits with 0
for i in range(n):
x = random.random()
y = random.random()
z = (x,y)
if x**2+y**2 <= 1:
hits += 1
else:
del z
# use hits and n to compute PI

After constructing obj1 = myClass(12) and calling class function obj1.printInfo(), I am getting an error - AttributeError: type object 'myClass' has no attribute 'arg1' What might be the source of the problem ??
class myClass(object):
def __init__(self, arg1, arg2 = 0):
self.arg1 = arg1
self.arg2 = arg2
def printInfo (self):
print myClass.arg1, myClass.arg2
obj1 = myClass(12)
obj1.printInfo()
Thanks !
A: You want to use replace the body of printInfo(self) with:
def printInfo(self):
print self.arg1, self.arg2
The use of self here is not to specify the scope, as it is sometimes used in Java (MyClass.this) or in PHP. In this function, self is actcually the object that contains arg1 and arg2. Python is very explicit in this manner. In your previous method, you assigned arg1 and arg2 for self, so you should expect to get arg1 and arg2 back off of self.
With regard to your second question, if you want a "class" function (i.e. a static method), then you still need a reference to your obj1 to access its properties. For example:
class MyClass(object):
def __init__(self, arg1, arg2 = 0):
self.arg1 = arg1
self.arg2 = arg2
@staticmethod
def printInfo(obj):
print obj.arg1, obj.arg2
obj1 = MyClass(12)
MyClass.printInfo(obj1)
Also be sure to read PEP8 when you get a chance :)
A: Brain fart, eh? Switch myClass.arg1 to self.arg1:
def printInfo (self):
print self.arg1, self.arg2
A: You can do it like this:
def f1(arg1, arg2):

I tried to mix the tf layer inside my other keras layers.
input = Input(shape=state_shape)
conv = Conv2D(64, (6, 6), strides=(1, 1), activation='relu')(input)
spatial_softmax = tf.contrib.layers.spatial_softmax(conv, name='spatial_softmax', data_format='NHWC')
fc = Dense(128, activation='relu')(spatial_softmax)
fc = Dense(128, activation='relu')(fc)
output = Dense(action_size, activation='softmax')(fc)
Model(inputs=input, outputs=output)
But when I run the code I get the following error
AttributeError: 'Tensor' object has no attribute '_keras_history'
Any idea?
Thanks!
Edit: It's not the same question as here, I am asking for a layer with trainable weights and not a deterministic layer. Do the gradients will backprop to the layer ?
A: I believe you would need to put that inside a Lambda layer:
spatial_softmax = Lambda(lambda x: spatial_softmax(x, name='spatial_softmax',
data_format='NHWC'))(conv)

</div>
@endforeach
What javascript or something else should I use to pop up this model ?
A: $('.buttonClass').on('click', function(){
$('#modalID').fadeIn();
});
modalID has to be determined by a data-attribute that you can give to your buttons. For example
<button type="button" class="open" data-dismiss="modal" data-id={{$image->image_id}}>
And then in JavaScript add
$('.buttonClass').on('click', function(){
let modalID = '#' + $(this).data('id');
$(modalId).fadeIn();
});
A: Add class="modal-open" to your as
jQuery method
$('.modal-open').on('click', function() {
$( '#'+$(this).data('target') ).show();
})
Typing from my head so there could be typos.
If the as and .modals are added dynamically then:
$(this).on('click','.modal-open', function() { ...

My goal is to create a new type of product (different from Coffee and Brewer)
Here it says that we can create our own type of page and tranform them as product via the ecommerce tab:
https://docs.kentico.com/k11/e-commerce-features/configuring-your-store/configuring-product-page-types
What I should see:
What I see: (no ecommerce tab on the left)
I checked on the content module and I see a macro for a field called "Visible condition", is it why the tab is hidden ?
I'm connected as "administrator" so it should not be a problem of permissions.
Do you know how to make it visible ?
A: You are missing lots of tabs on the left like Fields, Layout, Alternative forms, Search as well. Make sure you macro signature is correct by going to System app > macro signature to resign them. Also make sure your hashsalt is the same in both Admin and MVC web.config.

After my first attempt at coding this solution, my localStorage entry looked like this:
616845040,796177849,848184043,1133088406,1205053317,1478518197,1525440546,1686606993,1753347541,1908577591,2056496592,-864967541,-1185668678,-835401591,-1017499054,-559563441,-1842092814,-1069291933,-1887162563
19 hashes, 210 bytes of data.
A little later, I revisited the code. Instead of just dumping the integers as decimal strings, I converted them into actual binary data. In other words, each hash is now a string of four characters in length representing the binary value of the integer. My localStorage entry now looks like this:
$ÄNð/tµ¹2BëCGÓ§X eµZì`"dhõÕqÂ7z¥Ðￌq¤ﾹT!ºￎ4ÈￃZ2R¥½Oﾒ3äòCæcﾏ/=
19 hashes, 76 bytes of data (There's some non-printable characters in there)
That's a savings of 63.8%.
Now, I am well aware that localStorage provides, by default, 5MB of storage space. I could easily store tens of thousands of hashes with the first method with no issues at all. But I like being efficient. I certainly wouldn't want a 5MB file on my computer when I could have the same data in 1.8MB (same compression ratio as above). That's why I save all my PNGs as indexed-palette when possible.
Is this a good mentality to have? Or am I just being pedantic? I guess this question could be summarised as: Should I compress, or just not care due to having more resources than I'll ever need?
A: Pedantic is good when coming to code. Compress when you can, but be sure that when reading your code, it's still readable and understandable that hashes are kept in whatever way.
What I mean is, don't sacrifice your code readability and maintainability for efficiency.

After packaging the NuGet package and referencing it, the bindings do not seem to be triggering at all from the package. When hovering over the [Binding] keyword, there's no referenced namespace and the text is in white.
Is it possible to have BindingAttribute recognized in a NuGet package at all?
A: Given you tagged specflow, I assume this question is really "How can I make Specflow use bindings from external assemblies". A quick google search of that question finds this page on the Specflow wiki.
The important part from the page:
In order to use bindings from an external binding assembly, you have to list it (with the assembly name) in the app.config of the SpecFlow project. The SpecFlow project is always included implicitly. See more details on the configuration in the <stepAssemblies> section of the configuration guide.
<specFlow>
<stepAssemblies>
<stepAssembly assembly="MySharedBindings" />
</stepAssemblies>
</specFlow>
Otherwise, NuGet doesn't do anything special, it's just a delivery mechanism. By the time the compiler runs, it doesn't know whether each assembly was from a project or package reference. At runtime it's irrelevant.
It's common for libraries like MVC or Specflow to only discover classes from the calling assembly, not all assemblies, so you usually have to read the docs of the framework you're using to find out how to register additional assemblies. There is no single or common way, each library or framework has its own technique.

from django.contrib import admin
from django.contrib.auth.models import User
admin.site.unregister(User)
class CustomUserAdmin(admin.ModelAdmin):
filter_horizontal = ('groups',)
list_display = ('username', 'email', 'last_login')
admin.site.register(User, CustomUserAdmin)
however after doing this and testing on the admin site the changes aren't reflected.
If I remove the last line:
admin.site.register(User, CustomUserAdmin)
it throws an error saying that User isn't registered so i think it's recognizing the new admin just not taking any effect.
A: Not sure if that's a case, but maybe you should inherit from from django.contrib.auth.admin import UserAdmin and not from the ModelAdmin.
A: It may be simpler to just override the built-in UserAdmin, changing what you need:
from django.contrib import admin
from django.contrib.auth.models import User
from django.contrib.auth.admin import UserAdmin
admin.site.unregister(User)
UserAdmin.filter_horizontal = ('groups',)
UserAdmin.list_display = ('username', 'email', 'last_login')

I'm using the following code to authenticate it originally.
var result = await new AuthorizationCodeMvcApp(this, new AppFlowMetadata()).
AuthorizeAsync(CancellationToken.None);
if (result.Credential != null)
{
var service = new YouTubeService(new BaseClientService.Initializer
{
HttpClientInitializer = result.Credential,
ApplicationName = "YouTube Upload Tool"
});
}
And this is my AppFlowMetadata class.
public class AppFlowMetadata : FlowMetadata
{
private static readonly IAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = "ID",
ClientSecret = "SECRET",
},
Scopes = new[] { YouTubeService.Scope.YoutubeUpload },
DataStore = new EFDataStore(-1) // A data store I implemented using Entity Framework 6.
});
public override string GetUserId(Controller controller)
{
return "test";
}
public override IAuthorizationCodeFlow Flow
{
get { return flow; }
}
}
If anyone can suggest anything, I would greatly appreciate it. Thank you.
A: While this is not an answer, this is how I got around it. I had to create the GET request for authorisation (redirect your user to the url you get back and set your Controller Action to receive the callback specified in your Google Developer Console) and the PUT request for the Token (which I then stored using EF6) manually. I used System.Net.Http.HttpClient to make these requests, which was quite straight forward. See this link for all the details I needed to get this working.
It was the only way I could set the access_type to "offline". If the .NET API does this, I'm still curious to find out how.
With the token data stored, I now use the API to validate and refresh the token when I need to. I actually did this in a server side console application rather than a MVC app (hence the EF token persistence).
UserCredential credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
new ClientSecrets
{
ClientId = "ID",
ClientSecret = "Secret"
},
new[] { YouTubeService.Scope.YoutubeUpload },
"12345",
CancellationToken.None,
new EFDataStore(-1) // My own implementation of IDataStore
);
// This bit checks if the token is out of date,
// and refreshes the access token using the refresh token.
if(credential.Token.IsExpired(SystemClock.Default))
{
if (!await credential.RefreshTokenAsync(CancellationToken.None))
{
Console.WriteLine("No valid refresh token.");
}
}
var service = new YouTubeService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "MY App"
});
I hope this helps others.

In the samples I have seen for Prism the Shell window has no explicit depencies so when it is resolved in the CreateShell of the bootstrapper it all stops there. Because of this modules must be explicitly resolved in the InitializeModules method.
Likewise, inserting views into the shell is usually done by resolving them in the module Initialize method and explicitly setting them to a given region, thus using the DI container more as a service locator.
Does anybody know how to link things together to enable a single resolve in Prism?
A: There is an application which has two modules Module1 and Module2.
You are saying the following is
public ShellView(IUnityContainer container, IRegionManager regionManager, IEventAggregator eventAggregator, IModule1 mod1, IModuel2 mod2)
{
}
better than this
public ShellView(IUnityContainer container, IRegionManager regionManager, IEventAggregator eventAggregator)
{
}
public class IModule1 : IModule
{
public void Initialize()
{
var container = ServiceLocator.Current.GetInstance<IUnityContainer>();
var regionManager = ServiceLocator.Current.GetInstance<IRegionManager>();
regionManager.RegisterViewWithRegion("Region1", typeof(Module1View));
}
}
public class IModule2 : IModule
{
public void Initialize()
{
var container = ServiceLocator.Current.GetInstance<IUnityContainer>();
var regionManager = ServiceLocator.Current.GetInstance<IRegionManager>();
regionManager.RegisterViewWithRegion("Region2", typeof(Module2View));
}
}
Which way one could do the project depends on many factors. For example I can selct the second approach citing
Modularity
The second approach is more loose coupled than the first. The first approach forces the app to declare the modules it is going to use.
I can decide my app will only define regions and I will create modules later on and inject the views to the respective regions.
I am not saying this is absolutely the case as you can very well select the first approach saying as the modules itself won't have any reference about where it is going to be used that approach is more modular. All I am saying is there are options about how to go about a problem and limiting the options is generally not a good idea.

So I want to schedule a job / task on appengine to run at the events date/time to send a push notification to all subscribers.
Example:
User A creates an event that will start on Saturday next week on 8 pm. User B and User B subscribe for this event.
On Saturday 8 pm a job/task should start to send the push notifications to User B and User C to inform that the event has started.
My question is:
How do I implement something like this in an efficient way on appengine? I want to say, start a Task for the Event on Saturday at 8 pm. There are Cronjobs and TaskQueues. Cronjobs can not be created programmatically. TaskQueue needs to be pulled and can not be scheduled to pull at a given date / time, right?
So the only solutions I see is to create a cronjob that will run every minute to check if there is a Event that starts right now.
An event can be created at any time and any day in the week. However the most events are created for the weekend and There are days when no event has been created for. So running a cronjob periodically ever minute is very inefficient. Im looking for a smarter solution, any ideas?
A: Indeed, based on your description, the solution is to create a cron job that checks for new events that start right now.
However, you should be careful not to exceed the 60 second window you have for each cron job. If you have a lot of events, you probably should move the actual processing from the cron job to background tasks using Push Task Queues.
You may take a look to this post for a combination of cron jobs and Task Queues.

ImportError: could not import module "PySide.QtXml"
When I try to convert the app shipped with cx_Freeze\Samples\PyQt4, it runs with no problems.
In this sample application there is just a simple QDialog called, but in my application I used QtDesigner for GUI design and I load it with PySide UiLoader directly in my py.file:
class MainWindow(QtGui.QMainWindow):
def __init__(self,parent=None):
QMainWindow.__init__(self)
loader = QUiLoader()
self.ui = loader.load('xxxx.ui',self)
QMetaObject.connectSlotsByName(self)
setup.py
from cx_Freeze import setup, Executable
# Dependencies are automatically detected, but it might need
# fine tuning.
buildOptions = dict(packages = [], excludes = [])
import sys
from cx_Freeze import setup, Executable
from PySide import QtXml
base = 'Win32GUI' if sys.platform=='win32' else None
options = {
'build_exe': {
'includes': 'atexit'
}
}
build_exe_options = {
'includes': ['atexit'],
}
executables = [
Executable('xxx.py', base=base)
]
setup(name='xxx',
version = '0.10',
description = 'First try',
options = dict(build_exe = buildOptions),
executables = executables)
In my opinion there's some problem using UiLoader when converting with cx_freeze but I have no clue how to overcome this issue.
A: This seems to be an old question. Still I am answering as it would help someone who is looking for a solution.
The solution is so simple that you just need to add "PySide.QtXml" to the includes list. After this your setup.py will look like this
build_exe_options = {
'includes': ['atexit'],
'packages': ['PySide.QtXml'],
}

Can anyone help me find a solution? Thanks.
Sorry for not attaching the code. Here it is.
#data is a 3d matrix. S is a shapefile.
[X,Y,Z]=meshgrid(xgr,ygr,zgr);
S = shaperead(filename);
hold on;
pcolor3(X,Y,Z,data); # show the 3d matrix
mapshow(S,'FaceColor',[0.5 0.5 0.5]); # show the base map
hold off;
I'm not sure if the problem is in function mapshow. When I use mapshow in a 3d scatterplot, it is good. However, this time, it's bad.

Just above the issue I assigned the distance value to a new Dictionary and match the values based on address, but this has limitations with other changes I need to make to get to the end state with the app. I have tried lots of different ways to assign the distance to an existing key:value pair in Response or create a new key value pair in Response. Some examples below:
item.District = d //Error: Cannot assign to property: 'item' is a 'let' constant
item[Distance] = d //Error: Cannot find 'Distance' in scope
item["Distance"] = d //Error: Value of type 'Response' has no subscripts
How do I create a new key:value pair in Response, or assign the value of d to the District key? Thanks so much in advance for any help you can provide.
A: First thing, your instance variables on your Response struct are a little confusing because they don't follow the convention of having variables in all-lowercase, and types capitalized.
Second, for your first error in your list of 3, item is a let constant because it is inside a for loop. You can get around this by declaring the loop this way:
for var item in self.response {
// I can modify item in this loop because it is declared a var
}
The other two errors are pretty self-explanatory, I think.
Third, it sounds like you want to alter your Response object programmatically after receiving it, which is also a bit of an anti-pattern. If you want to modify an object you have downloaded from a server, that's understandable, but it is confusing for someone reading your code to alter an object called "Response." (once you modify it, it no longer represents the server response for which it is named) At a minimum, you could change District to be a computed property of Response.
All that said, if you instantiate your loop using the var keyword, you should be able to do:
item.District = d

<soapenv:Envelope>
<soapenv:Body>
<s:Envelope>
<s:Body>
<soap:Envelope>
<soap:Body>
<soap-env:Envelope>
<soap-env:Body>
From the service I'm trying to access (Marketing Cloud) the documentation references various tags <soap-ENV:Body>, <s:Envelope>, etc. After trying to get successful response using "Retrieve" Soapaction finally worked by using "<s:Envelope>", "<s:Body>, etc.
Is the difference between the tags version 1.2 and another version?
I think if I better understand the tags should help understand how to properly submit to the Marketing Cloud service using tools such as Postman.
Here are some examples and just not sure how to get these various ones working in Postman
Example 1
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

A: I will go step by step through your program and improve it.
First of all creating arrays like this:
player1 = [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
player2 = [2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]
Is always a bad practice. Since you already use numpy in your project it's easy to create them like this:
player1 = np.ones(32, dtype=np.uint8)
player2 = np.full(32, 2, dtype=np.uint8)
However you don't really need those arrays anyway. You can just have an integer which keeps track of the remaining pieces. reamining_pieces = 32
To make the whole think easier I created a Player class which contains a Player number and the remaining Pieces.
class Player(object):
def __init__(self, number):
self.remaining_pieces = 32
self.number = number
Now after this you have a lot of functions which aren't really necessary. They are so simple that there is no advantage of writing a function for them.
So for example instead of writing
def create_board():
board = np.zeros((ROW_COUNT, COLUMN_COUNT))
return board
board = create_board()
It's a lot simpler and easier to read if you just write
board = np.zeros((ROW_COUNT, COLUMN_COUNT))
Same goes for def drop_piece(board, row, col, piece) and def is_valid_location(board, row, col) which both just add unnecessary complexity to it.
Step by step explanation
First, we start with a tuple of all directions:
directions = [(-1, -1), (-1, 0), (-1, 1), (1, 1), (1, 0), (1, -1), (0, 1), (0, -1)]
And we now want to go in all directions and every time we start at row, column which is where the newly placed piece is located.
for d in directions:
x = row
y = column
And since we don't know how far we have to go we use a while loop and take the first step in the direction. Because We don't want to go outside of the board we immediately check if we are still on the board. If we are, we can continue.
while True:
x = x + d[0]
y = y + d[1]
# check if we are still on the board
if (x in range(8)) and (y in range(8)):
For the following steps let's use this as an example:
[[0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 0]
[0 0 0 1 2 0 0 0]
[0 0 * 2 1 0 0 0]
[0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 0]]
The star is where has just been placed a one. If we go one step to the left, we will encounter a 0 and know that we don't have to go any further. That's what
if board[x][y] == 0:
break
Does.
If we now go to the right. We will first encounter a two and it just get's ignored and we go one step further to the right.
Here we finally find a one. So we know that between row, column and x, y every number can be converted to a one. To do that we start at row, column and move once again until we reach x, y. On the way we convert every number to a one:
if p.number == board[x][y]:
print(f'found {p.number}: x = {x + 1}, y = {y + 1}')
i = row
j = column
while i != x or j != y:
i = i + d[0]
j = j + d[1]
print(f'changed : x = {i + 1}, y = {j + 1} to {p.number}')
board[i][j] = p.number

why it doesn't work in Internet Explorer, but ok for other browser.
Many thanks
A: IE cannot read your imagearray.
Your last image in the array has a comma after it, followed by a comment stating to not include a comma after the last element. The IE error indicates your imagearray is empty, I suspect this is the problem.

Engine: PCRE
RegEx1: (?<=<prefix>)(.*)(?=<suffix1>)
RegEx2: (?<=<prefix>)(.*)(?=<suffix2>)
Result1: <content1>
Result2: <content1><suffix1><prefix><content2>
The desired result for RegEx2 is just <content2> but it is obviously greedy.
How do I make RegEx2 non-greedy and use only the last matching lookbehind?
[I hope I have translated this correctly from the NoteTab syntax. I don't do
much RegEx coding. The <prefix>, <content> & <suffix> terms are just meant to represent arbitrary strings. Only the "<" in the "?<=" lookbehind command is significant.]
I suspect it is something simple but after too many hours of searching I'm
giving up on solving it myself.
Thanks for the help
Art
A: I suggest you use:
(?<=<prefix>)(((?!<prefix>).)*)(?=<suffix2>)
This makes sure that there can be no <prefix> inside the match. The complete match result will be <content2>
A: Put something greedy in front of it?
(?:.*)(?<=<prefix>)(.*)(?=<suffix2>)
Since the greedy (?:.*) will gobble as much as it can, only the minimum will be matched by the rest of the pattern - effectively making the rest non-greedy.
The non-greedy .*? might also work:
(?<=<prefix>)(.*?)(?=<suffix2>)
A: I just had the same problem. But in my case it was
(?<=<prefix>)(?:.(?!<prefix>))*(?=<suffix>)
That did what I wanted.
This expression will match anything that is a concatenation of characters between <prefix> and <suffix> and doesn't contain the substring <prefix>. (I think so. I'm not very good at regexp.)

Such that in case connection is lost to a server due to loss of internet connection, there is a possibility to communicate between all devices with software containing peer to peer connections made through WebRTC without being connected to cell towers or the internet.
A: There could be a couple of different ideas mixed into your question, so it may be worth being quite precise in the answer.
WebRTC is IP and HTTP based, as mentioned in the comments, so it does need IP connectivity, but that connectivity could be a private network and not necessarily the internet, if both devices were connected to the same private network, or to two interconnected private networks.
However, you also say that cell towers are down - in this case there would be no connectivity to the cellular network, so the devices would only be able to communicate if they both had WiFi capabilities and were connected to the same WiFi networks, or to separate WiFi networks that had some sort of connection between them (I'm ignoring wired connections to the devices as I doubt this is what you are thinking of).
If you meant, could phones connect in a peer to peer manner if the network went down so they could work together to make and route calls, this is something which has been discussed and looked at quite extensively and certainly chat apps existed and exist which can do this, possibly the best known being the now discontinued FireChat (https://en.wikipedia.org/wiki/FireChat).
Its a constantly evolving field so any links will age quickly, but if you search for 'Mobile Mesh Networking' you will usually find the right material.
And, in answer to your original question - WebRTC itself does not enable peer to peer connectivity.

However, when i was testing it with downstream application where i consume from kafka and publish it to downstream. If downstream is down, the messages were still getting consumed and was not replayed.
Or lets say after consuming from kafka topic , in case i find some exception in service activator, i want to throw some exception as well which should rollback the transaction so that kafka messages can be replayed.
In brief, if the consuming application is having some issue , then i want to roll back the transaction so that messages are not automatically acknowledged and are replayed back again and again unless it is succesfuly processed.
A: That's not how Apache Kafka works. There is the TX semantics similar to JMS. The offset in Kafka topic has nothing with rallback or redelivery.
I suggest you to study Apache Kafka closer from their official resource.
Spring Kafka brings nothing over the regular Apache Kafka protocol, however you can consider to use retry capabilities in the Spring Kafka to redeliver the same record locally : http://docs.spring.io/spring-kafka/docs/1.2.2.RELEASE/reference/html/_reference.html#_retrying_deliveries
And yes, the ack mode must be MANUAL, do not commit offset into the Kafka automatically after consuming.

I want to update the "remaining" labels when a row is either inserted or deleted. The problem comes when I call my "setLabels" method in controller didChangeObject: delete and insertRowAtIndexPaths. With this (https://www.dropbox.com/s/fcj8h3a03pfud6x/Screenshot%202015-02-04%2019.11.46.png?dl=0 ) implementation the labels only update when the next cycle comes. (If i add one, nothing will happen until I add another or delete one. I'm left with the label values that correspond to the tableView before the most recent change. Always one step behind)
I added an NSLog to verify the method is being called (it is) so I have no idea why my labels won't update till controllerWillChangeContent is called for a second time.
PS: my set labels method is simple. It uses my "getSum" method which gets the sum of an entities attribute and sets the label

printf("%p\n",(*korzen)->right);

int main()
{
drzewo korzen =NULL;
char *words[10]={"alfabet","borixon","aaaaaa","zombie","bobas","kamil","agnieszka","kokos","zamach"};
for(int i=0;i<9;i++)
add(&korzen,words[i]);
printf("test1\n");
printftree(&korzen);
printf("test");
erease(&korzen);
return 0;
}
So this is my implementation of binary tree. Which loads 10 words to the tree . Sadly during 'printing' this tree I came across a problem which is core dumped. I don't know why but one of the structurs "has" (*korzen)->left that isn't NULL, my funcion wants to acess it,and the core dumped appears. After adding two lines
if(strcmp((*korzen)->string,"boril\0")==0)
(((*korzen)->right)->left)->left=NULL;
it works fine, but I don't know why i have this issue. Another issue is that despite having such a line as:
(*korzen)->hmanyt=1;
Afterall it doesn't have this value ... (only first word has hmanyt==1) . Help would be really appreciated.
A: It is a bad idea to assign NULL to a pointer which you want to free. Change place of *korzen=NULL; and free(*korzen); in your function erease:
Adapt your function erease like this:
void erease(drzewo* korzen)
{
if ( *korzen == NULL )
return;
if( (*korzen)->left !=NULL )
{
erease(&((*korzen)->left)); // (*korzen)->left is freed in erease
}
if( (*korzen)->right !=NULL )
{
erease(&((*korzen)->right)); // (*korzen)->right is freed in erease
}
free(*korzen);
*korzen=NULL;
return;
}
If you insert a new node in your tree you have to initialize its childs (*korzen)->left and (*korzen)->right with NULL. Further the type of drzewo is struct Tree*, so sizeof(drzewo) gives the size of a pointer not the size of struct Tree.
void add(drzewo* korzen,char word[])
{
while( *korzen != NULL )
{
int cmp = strcmp( ( *korzen )->string, word );
if ( cmp == 0 )
{
((*korzen)->hmanyt)++;
return;
}
else if( cmp<0 ) {
korzen=&((*korzen)->right);
}
else if (cmp>0 ) {
korzen=&((*korzen)->left);
}
}
// allocate new node and initiialize
*korzen=malloc(sizeof(struct Tree)); // allocat sizeof struct Tree ( not sizeof pointer to Tree)
( *korzen )->left = NULL; // <- left child is null
( *korzen )->right = NULL; // <- right child is null
strcpy(((*korzen)->string),word);
(*korzen)->hmanyt=1;
return;
}
Finally your function printftree:
void printftree(drzewo* korzen)
{
if ( *korzen == NULL )
return;
if( (*korzen)->left != NULL)
printftree(&((*korzen)->left));
printf("%s(%d)\n",(*korzen)->string,(*korzen)->hmanyt);
if((*korzen)->right != NULL)
printftree(&((*korzen)->right));
return ;
}

In Java I have written the following regex, and looks like that's what i need:
String regex = "([\\w&&\\D]|[\\u0410-\\u044F]|[\\s])+"
In GWT this works not as intended: it accepts #$%^... etc signs. I have to write the first group as [a-zA-Z_] to get what I want: letters and _ sign.
Moreover, before my modification, there was an old regex, which looked like
String regex = "([\\w&&\\D]+|[\\u0410-\\u044F]+|[\\s]+)";
Basing on my Java experience it should accept only words combined from Latin letters and _ sign, or words combined only of Cyrillic letters or words from whitespace. But in fact in GWT it accepts all words, and even &*(... etc signs.
So the questions are:
1) Why is [\\w&&\\D] not equivalent to [a-zA-Z_] in GWT?
2) Why does [...]+|[...]+|[...]+ in GWT behave like ([...]|[...]|[...])+ in Java?
A: GWT generates JS, so the reason could be the regexp differences between JS and Java.

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE `USER`='trial_505813';
then
KILL 25685;
But can I do something like:
KILL (SELECT `ID` FROM INFORMATION_SCHEMA.PROCESSLIST WHERE `USER`='trial_505813')
to kill all processes from specified user with one query?
A: MariaDB has a KILL USER <name> command: https://mariadb.com/kb/en/kill/
MySQL does not implement this feature. You would have to fetch all the process id's for that user and write a loop to kill them one by one.
Example in Python:
import mysql.connector
cnx = mysql.connector.connect(user='root', password='xxxx', database='test')
cursor = cnx.cursor()
cursor.execute("SELECT id FROM INFORMATION_SCHEMA.PROCESSLIST WHERE USER = %s", ["trial_505813"])
result = cursor.fetchall()
for row in result:
cursor.execute(f"KILL {row[0]}")
I have to comment that killing queries or threads because of a lock wait timeout seems like a harsh solution. It's likely that you could optimize queries so they don't hold locks too long.
If the query is already optimized, you could be letting a transaction remain uncommitted too long. A transaction holds locks until the transaction is finished. So you need to finish transactions (COMMIT or ROLLBACK) promptly after the query is done.

My problem is when tapping on navigation bar, it doesn't update the TabBarView body e.g. RankingTable doesn't update; in the demo code below I have put the same data in the table but the date drop down above the table should be formatted differently since I pass in a different formatter into each datatable when navigation bar is tapped. Namely, in the 2nd screenshot, on Nav1, it still shows the same dropdown date format as in the 1st screenshot which is on Nav0.
Screenshot1:
Screenshot2:
If I put a simple widget such as Text in the TabBarView body, then it updates as expected when tapping on the navigation bar items, not sure whether this implies the problem is my custom RankingTable widget.
Also, despite the body doesn't update when tapping on a new item in navigation bar, if I switch tab e.g. from Tab1 to Tab2 and switch it back to Tab1, then the body gets updated correctly, matching with the corresponding navigation bar item. It feels like the body data did get updated when tapping navigation but it just didn't get rendered.

A: The problem lies in your State.
First, there is no need for a constructor in your state. You can access the variables of your widget by calling widget.youFinalField.
The problem is: when you return a new RankingTable the underlying state is not recreated but rebuilt (the build and the didUpdateWidget methods are called).
Because you passed you variables in the construct (which is only used the very first time) your formatter doesn't update.
The solution is pretty simple, instead of using a constructor in your state just access the variables through the widget.
Working code state code:
// this puts a scrollable datatable and optionally a header widget into a ListView
class RankingTable extends StatefulWidget {
final Map<DateTime, List<RankingBase>> rankingMap;
final bool hasHeaderWidget;
final String dateFormatter;
//final bool isPlayer;
RankingTable(this.rankingMap,
{this.dateFormatter, this.hasHeaderWidget = true});
@override
_RankingTableState createState() => _RankingTableState();
}
class _RankingTableState extends State<RankingTable> {
DateTime _selectedDate;
@override
void initState() {
super.initState();
_selectedDate = widget.rankingMap.keys.last;
}
DataTable buildRankingTable() {
widget.rankingMap[_selectedDate].sort(RankingBase.performanceSort);
String nameOrPair =
widget.rankingMap[_selectedDate].first is PlayerRanking ? 'Name' : 'Pair';
int rank = 1;
return DataTable(
columns: <DataColumn>[
DataColumn(label: Text('Rank')),
DataColumn(label: Text(nameOrPair)),
DataColumn(label: Text('Played')),
DataColumn(label: Text('Win Ratio')),
DataColumn(label: Text('Points Won-Loss')),
DataColumn(label: Text('Duration')),
],
rows: widget.rankingMap[_selectedDate].map((RankingBase pr) {
DataCell titleCell;
if (pr is PlayerRanking)
titleCell = DataCell(Text('${pr.name}'));
else {
// var pair = pr as PairRanking;
// titleCell = DataCell(Text('${pair.player1Name}\n${pair.player2Name}'));
}
return DataRow(cells: [
DataCell(Text('${rank++}')),
titleCell,
DataCell(Text('${pr.played}')),
DataCell(Text('')),
DataCell(Text('${pr.pointsWon} - ${pr.pointsLost}')),
DataCell(Text('${pr.duration}')),
]);
}).toList(),
);
}
@override
Widget build(BuildContext context) {
List<Widget> childrenWidgets = [];
if (widget.hasHeaderWidget) {
var dateDropdown = DropdownButton<DateTime>(
items: widget.rankingMap.keys
.map((date) => DropdownMenuItem(
child: Text(
'$date ${widget.dateFormatter}'), //yMMMEd
value: date,
))
.toList(),
value: _selectedDate,
onChanged: (value) {
setState(() {
_selectedDate = value;
});
},
);
childrenWidgets.add(dateDropdown);
}
childrenWidgets.add(SingleChildScrollView(
padding: EdgeInsets.all(20.0),
scrollDirection: Axis.horizontal,
child: buildRankingTable(),
));
return ListView(
padding: EdgeInsets.all(10.0),
children: childrenWidgets,
);
}
}
A: The reason why RankingTable doesn't change is because build method in the code uses fields (rankingMap, dateFormatter, etc.) stored in your state.
When StatefulWidget is created for the first time, it also instantiates relevant State object which then builds your widget in build method. Every time you call setState method, Flutter recreates Widget from scratch, whereas State object is being persisted.
Widgets are temporary objects, used to construct a presentation of the application in its current state. State objects on the other hand are persistent between calls to build(), allowing them to remember information.
This means, every time RankingTable widget is created, your build method in _RankingTableState makes use of the same values passed in the constructor/assigned in initState (even though widget object contains updated fields values). On the other hand, when you naviagte back and forth by using the TabBar, state object is recreated with current dateFormatter - that's why the table is updated in this scenario.
To make it work as intended, you should remove all final fields from your state object and refer directly to its widget to get all necessary values:
class RankingTable extends StatefulWidget {
final Map<DateTime, List<RankingBase>> rankingMap;
final bool hasHeaderWidget;
final String dateFormatter;
RankingTable(this.rankingMap,
{this.dateFormatter, this.hasHeaderWidget = true});
@override
_RankingTableState createState() => _RankingTableState();
}
class _RankingTableState extends State<RankingTable> {
DateTime _selectedDate;
@override
initState() {
super.initState();
_selectedDate = widget.rankingMap.keys.last;
}
DataTable buildRankingTable() {
widget.rankingMap[_selectedDate].sort(RankingBase.performanceSort);
String nameOrPair =
widget.rankingMap[_selectedDate].first is PlayerRanking ? 'Name' : 'Pair';
int rank = 1;
return DataTable(
columns: <DataColumn>[
DataColumn(label: Text('Rank')),
DataColumn(label: Text(nameOrPair)),
DataColumn(label: Text('Played')),
DataColumn(label: Text('Win Ratio')),
DataColumn(label: Text('Points Won-Loss')),
DataColumn(label: Text('Duration')),
],
rows: widget.rankingMap[_selectedDate].map((RankingBase pr) {
DataCell titleCell;
if (pr is PlayerRanking)
titleCell = DataCell(Text('${pr.name}'));
else {
// var pair = pr as PairRanking;
// titleCell = DataCell(Text('${pair.player1Name}\n${pair.player2Name}'));
}
return DataRow(cells: [
DataCell(Text('${rank++}')),
titleCell,
DataCell(Text('${pr.played}')),
DataCell(Text('${NumberFormat("0.##%").format(pr.won / pr.played)}')),
DataCell(Text('${pr.pointsWon} - ${pr.pointsLost}')),
DataCell(Text('${pr.duration}')),
]);
}).toList(),
);
}
@override
Widget build(BuildContext context) {
List<Widget> childrenWidgets = [];
if (widget.hasHeaderWidget) {
var dateDropdown = DropdownButton<DateTime>(
items: widget.rankingMap.keys
.map((date) => DropdownMenuItem(
child: Text(
'${DateFormat(widget.dateFormatter).format(date)}'), //yMMMEd
value: date,
))
.toList(),
value: _selectedDate,
onChanged: (value) {
setState(() {
_selectedDate = value;
});
},
);
childrenWidgets.add(dateDropdown);
}

My question is: is there even a point to having the node server listen for HTTP traffic as well? I guess what I'm unsure about is what percent of user clients' browsers support https or if there is any reason to allow http traffic.
My app requires native websockets as well (requires >2011 browsers) so I'd imagine that all browsers past that would support https. Are there any instances or situations where clients can't use https and have to connect over http? Perhaps some mobile devices?
What are the pros and cons towards listening for only https as opposed to opening up both port 80 and 443?

function createChannel() {
randomString = crypto.randomBytes(12).toString('hex');
const randomCategory = message.guild.channels.create(randomString, {
type: 'category',
permissionOverwrites: [
{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
},
],
});
message.guild.channels.create(randomString, {
type: 'text',
parent: randomCategory.id,
permissionOverwrites: [
{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
},
],
});
message.guild.channels.create(randomString, {
type: 'voice',
parent: randomCategory.id,
permissionOverwrites: [
{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
},
],
});
}
This should create a category, and populate it with a voice and text channel with the same name. However, when I run it the channels don't get their parent set correctly.
A: According to the documentation, you should pass the channel as a parent instead of the id. You should probably also await the category creation before making the children.
async function createChannel(){
const randomString = crypto.randomBytes(12).toString('hex'); //added const here since you're never overwriting
const randomCategory = await message.guild.channels.create(randomString, {
type: 'category',
permissionOverwrites: [{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
}]
});
await message.guild.channels.create(randomString, {
type: 'text',
parent: randomCategory,
permissionOverwrites: [{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
}]
});
await message.guild.channels.create(randomString, {
type: 'voice',
parent: randomCategory,
permissionOverwrites: [{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
}]
});
}
A: guild.channels.create returns a promise so you either need to use the .then() method or async-await to get randomCategory. At the moment it's just a pending promise, not the returned category:
// make the function an async function
async function createChannel() {
randomString = crypto.randomBytes(12).toString('hex');
// use await to wait the promise to resolve
const randomCategory = await message.guild.channels.create(randomString, {
type: 'category',
permissionOverwrites: [
{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
},
],
});
message.guild.channels.create(randomString, {
type: 'text',
// pass the randomCategory object, not just the id
parent: randomCategory,
permissionOverwrites: [
{
id: message.guild.id,
allow: ['VIEW_CHANNEL'],
},
],
});
message.guild.channels.create(randomString, {
type: 'voice',
// pass the randomCategory object, not just the id
parent: randomCategory,
permissionOverwrites: [

The laptop shows a C# file in this way:
The pc shows the same C# file in this other way:
Obviously, I prefer the laptop version. But I can't get the PC to color the text in the same way.
Any suggestion?
A: VS Code comes with 2 dark and 2 light themes (Dark, Dark+, Light and Light+). On your laptop, the Dark+ theme is active, on your PC, it's the Dark theme.
Changing the Theme
In VS Code on your PC, press F1, enter Theme, select Preferences: Color Theme, select Dark+ from the dropdown and you should be fine.
You can also press Ctrl+K, then Ctrl+T to open the theme dropdown.

A: Try using form_for since you are modifying an existing object @task:
<%= form_for :task, @task, :url => { :action => :update_subject} do |f| %>
<%= f.label :subject %>:
<%= f.text_field :subject %>
<%= f.submit %>
<% end %>
A: Remove the following line from the Javascript:
$('form').submit(confirmSelections);
This will no longer perform dynamic form validations, but should allow the Submit button to work. The real issue will be somewhere in the confirmSelections logic, and that will be dependent on what data has been entered on the form.
As a side note, this code looks like it would need some serious rework. At a minimum:
*
*Use form_for instead of form_tag
*Use f.submit instead of submit_tag (once the form_for is implemented)
*All of the Javascript is static, and should be moved into the assets pipeline, rather than be included inline
*All of the Ruby code in the block immediately following <h2>Task Detail:</h2> should be moved to the controller/action
*The code for @notes = Note.where(task_id: @task.id).order('created_at') should be moved to the controller/action
*The Javascript should select CSS classes, not explicit CSS styling, so that your presentation is able to be easily maintained
These should actually help make this template reasonably maintainable and separate the MVC concerns from one another.
A: Not Sure why or how this fixed it but i removed the first form and made the second form cover the whole view. The downside to this is I have to submit the whole page in order to update the subject.

type Server struct {
Etcd [] struct {
CertCn string `json:"cert_cn"`
} `json:"etcd"`
}
type CertExpiryReport struct {
Data struct {
Servers map[string]*Server
} `json:"data"`
Summary struct {
Expired int `json:"expired"`
Ok int `json:"ok"`
Total int `json:"total"`
Warning int `json:"warning"`
} `json:"summary"`
}
The following is the JSON content.
{
"data": {
"myserver1.mydomain1.org": {
"etcd": [
{
"cert_cn": "CN:something"
}
]
}
"myserver2.mydomain2.org": {

{
"cert_cn": "CN:something"
}
]
}
},
"summary": {
"expired": 0,
"ok": 31,
"total": 31,
"warning": 0
}
}
This is my code.
func printStuff() {
bytes, err := ioutil.ReadFile(jsonFile)
if err != nil {
log.Errorf("%s", err.Error())
os.Exit(1)
}
var certExpiryReport CertExpiryReport
err = json.Unmarshal(bytes, &certExpiryReport)
if err != nil {
log.Errorf("%s", err.Error())
os.Exit(1)
}
log.Info(certExpiryReport)
}
The output is the following. I am not getting any errors.
{{map[]} {0 31 31 0}}
Why can't GO parse the JSON? Is something wrong with my structs?
A: There is something wrong with the struct (or JSON). CertExpiryReport struct has additional level of nesting in Data field. Try to replace
Data struct {
Servers map[string]*Server
} `json:"data"`
With
Data map[string]*Server `json:"data"`
Also, your JSON gives me error (you forgot comma after first server description). Here is working test with change to your structs and JSON: https://play.golang.org/p/QwnHGc9MElb
Other way would be to put inside JSON "data" field "servers" field, and store content of data there. If you need more nesting.

The sample application is very simple (it is part of GTSAM) but when I run it, I am getting this linker error:
Severity Code Description Project File Line Suppression State Error LNK2019 unresolved external symbol __imp_clock referenced in function gk_CPUSeconds example D:\MyData\SourceCode\gtsam_win\cmake\example_cmake_find_gtsam\build\metis-gtsamDebug.lib(timers.obj)
and
Severity Code Description Project File Line Suppression State Error LNK2019 unresolved external symbol __imp__time64 referenced in function time example D:\MyData\SourceCode\gtsam_win\cmake\example_cmake_find_gtsam\build\metis-gtsamDebug.lib(timers.obj) 1
a search showed me that these two functions are part of MSVC libraries and they should in linked to the system.
How can I fix the issue?
It seems that the problem is mis match between the setting during library build and application build, but I can not find any linker setting different. Where to look for any such difference?
A: __imp_ prefix in unresolved external runtime library symbol from the linked library means the library was built with DLL runtime (/MD in C++ -> Code Generation -> Runtime Library).
If you build the application with static runtime (/MT) the symbols from the DLL runtime will be unresolved. Runtime settings should be the same for all compilation units.

private double d = 1000;
private boolean b;
private final int f = 100;
private char c = 'c';
so if the parameter is one of the above the method should return only d, b, f or c. How is algorithms should be implemented. I have tried to use regex to strip the word after the types but it became very complicated. Can anyone give me some clues, thanks
A: try this
String type = str.replaceAll(".*\\s(.)\\s*=.*", "$1");
A: You can take the string before the equal sign without regex:
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
while(true){
String theString = sc.nextLine();
String left = theString.split("=")[0].trim(); // Split into variable part and value part
int lastSpace = left.lastIndexOf(" "); // there must be a space before a variable declaration, take the index
String variableName = left.substring(lastSpace+1); // take the variable name
System.out.println(variableName);
}
}
If you're implementing this on Python, it's much easier:
the_string = 'private double d = 1000;'
print the_string.split('=',1)[0].strip().rsplit(' ',1)[1]

Currently I'm inserting some items into the db in a for-loop, but if I make a one sql-query out of the inserts and insert them at the end of the process, this would help me reduce the time that is needed to connect to the MySQL db, since there is no need to make a new connection for each item.
Problem: I need the auto increment id's from those inserts. Now I can get them with the lastInsertId() -function, but only when I insert them one by one.
Question1: Is it even possible to get all the AI-id's from a multiple row -insert?
Question2: If it's not possible to get the id's from a multi-row-insert, is it possible to keep the connection open as long as all the items has been saved?
Maybe1...: I thought that maybe I could get the last insert id of the multi-row-insert, and then calculate the other id's based on how many inserts I made. But I'm not sure how the mysql actually works. If there are many other connections, is there a possibility that the other connections get some of the AI values that should belong to our current connection? This would end up in a situation where I should have id's: 1, 2, 3, but other connection stole some of these and we end up having: 1, 3, 5, and thus, the calculating won't work. I'm not an expert with the MySQL, and I cannot find a decent explanation of this in the docs.
Maybe2...: I was also thinking that if all else fails, I could get the just inserted id's with a SELECT -query. This could be faster than the original way if there are more than 2 items to be inserted. Or could it? The math would be that I insert 3 items in a one query and get the just inserted id's with one, VS I insert 3 items in 3 queries. But when would this be meaningless optimization and when an actual time saving feature?
Conditions:
I'm using Symfony2 -framework and Doctrine DBAL for the connections. One item has 20 columns worth of data. 1/3 of the columns are TINYINTs, 1/3 are VARCHARS of varying lengths but usually we are talking about short strings of 5-15 chars. And 1/3 of the columns are INT's and DOUBLE's that are small values as well. There can be anything of 1 to 60 items to be inserted at a time. I think about 90% of the inserts have around 1-6 items in a one session.
Update:
I've been testing this out and it seems that the DBAL doesn't close the connection but re-uses the already created connections by default. This is good.
I also tested the inserting of multiple items in one query VS inserting them one at a time. Results are not what I expected.. It didn't matter how many items I inserted, but the time it took was roughly the same. This sparks up a question: why? One might think that 100 inserts individually is slower than one insert with 100 rows, but this didn't seem to be the case. Does anyone have any insights on this behaviour? Why doesn't it work like I thought it would?

Here, I'm trying to add a node on tap... but I couldn't figure out how to get the specific coordinates to pass to the rendererPosition property of the new node.
cy.on('tap', function (e) {
if (e.cyTarget === cy) {
//var pos = $(this).position().left, //tried this, as jquery
//posY = $(this).position().top; //positioning without success
var idNum = cy.nodes().size();
var setID = idNum.toString();
cy.add([{
group: "nodes",
data: {
id: "n" + setID
},
renderedPosition: {
x: e.pageX, //- posX,
y: e.pageY //- posY
},
}]);
}
});
Using the same code but binding with the $('#cy').click function, it works... but with cy.on('tap') way, the event e doesn't have the pageX and pageY properties, neither can I get the element position using the $(this).position() function.
I really prefer using tap, as I'm trying to develop my application also for mobile interfaces.
Thanks in advance.
EDIT: Using @darshanags observation and this link, I solved this way:
var idNum = cy.nodes().size(),
setID = idNum.toString(),
offset = $("cy").offset(),
position = {
x: e.originalEvent.x - offset.left,
y: e.originalEvent.y - offset.top
};
cy.add([{
group: "nodes",
data: { id: "n" + setID },
renderedPosition: {
x: position.x,
y: position.y
},
...
}]);
A: Your usage of is incorrect, Cytoscape's .position() works a bit differently to jQuery's position():
Get the position and use it:
var idNum = cy.nodes().size(),
setID = idNum.toString(),
position = {
x: e.cyTarget.position("x"),
y: e.cyTarget.position("y")
};
cy.add([{
group : "nodes",
data : {
id : "n" + setID
},
renderedPosition : {
x : position.x,
y : position.y
}
}]);
Docs: http://cytoscape.github.io/cytoscape.js/#collection/position--dimensions/node.position
A: I answered this elsewhere, but had come across both these questions while trying to make this work, so I'll post it here, too.
In cytoscape.js 3.2, there are convenience functions for this:
cy.on("tap", function(e) {
cy.add([{
group: "nodes",
id: "testid",
renderedPosition: {
x: e.renderedPosition.x,
y: e.renderedPosition.y,
},
});
});
This ends up being equivalent to (assuming you've set container: $("#cy-container")):
cy.on("tap", function(e) {
let canvas = $("#cy-container").find("canvas").get(0);
cy.add([{
group: "nodes",
id: "testid",
renderedPosition: {
x: e.originalEvent.pageX - $(canvas).offset().left,
y: e.originalEvent.pageY - $(canvas).offset().top,
},
});
});

I have an Excel document where from cell A to L I have a block of data.
Row A has the name of an item, Row G has the items' price
As you can see, the items are unordered in the table, is it possible to get every line where A = Item1 and then use that to get all the prices? G
A: The simplest way to achieve that would be to just set a filter - Set the cursor to the header row, and select Data -- Filter. Then you can filter to your hearts content. (Consider adding the header row if you don't have one)
Another way to achieve the same functionality is to select Home -- "Format as Table". Confusing name, but a bit more versatile.

More concise:
createFoo(): Observable<Foo> {
return this.step1()
.flatMap((result: Bar) => {
const processedResult = { ..., result }
return this.step2(processedResult)
});
}
More readable:
createFoo(): Observable<Foo> {
return this.step1()
.map((result: Bar) => {
const processedResult = { ..., result }
return processedResult;
})
.flatMap((processedResult: any) => {
return this.step2(processedResult);
})
.map((result: Foo) => {
return result;
});
}
The first variant only uses one mapping function and is generally a lot less noisy, but I also find it more difficult to tell at a glance what's actually happening. It also seems like it wouldn't scale well if I had more than two observables that needed to be chained.
The second variant is more noisy, with three times the function calls, but I also find it better at explaining what types are output where and how data is processed over the course of the stream. It also makes it much clearer how flatMap differs from the regular map, which is something I've had some trouble keeping my understanding straight on.
Is there a convention with RxJs that favors one or the other? Or is it personal preference?

I initialize a room object from Room class with property map of type ArrayList like this:
Room room1 = new Room()
{
map = new ArrayList {
new ArrayList(new int[] { 1, 1 } ),
new ArrayList(new int[] { 1, 1 } ),
new ArrayList(new int[] { 1, 1 } )
}
}
Then I override ToString() method of the class Room
public override string ToString()
{
return "Room ["+map.Count+","+map[0].Count+"]";
}
Debug.Log(room1);
results in error:
'object' does not contain a definition for 'Count' and no accessible
extension method 'Count' accepting a first argument of type 'object' could
be found (are you missing a using directive or an assembly reference?)
if I change ToString override as follows:
{
return "Room ["+map.Count+","+map[0]+"]";
}
then the result of
Debug.Log(room1);
is "Room [3,System.Collections.ArrayList]"
thus I came to conclusion that I get the error:
System.Collections.ArrayList does not contain a definition for 'Count'
What is going on?

public event EventHandler SomeEvent;
...
{
....
if(SomeEvent!=null)SomeEvent();
}
In a multi-threaded environment, how does this code guarantee that another thread will not alter the invocation list of SomeEvent between the check for null and the invocation of the event?
A: As you point out, where multiple threads can access SomeEvent simultaneously, one thread could check whether SomeEventis null and determine that it isn't. Just after doing so, another thread could remove the last registered delegate from SomeEvent. When the first thread attempts to raise SomeEvent, an exception will be thrown. A reasonable way to avoid this scenario is:
protected virtual void OnSomeEvent(EventArgs args)
{
EventHandler ev = SomeEvent;
if (ev != null) ev(this, args);
}
This works because whenever a delegate is added to or removed from an event using the default implementations of the add and remove accessors, the Delegate.Combine and Delegate.Remove static methods are used. Each of these methods returns a new instance of a delegate, rather than modifying the one passed to it.
In addition, assignment of an object reference in .NET is atomic, and the default implementations of the add and remove event accessors are synchronised. So the code above succeeds by first copying the multicast delegate from the event to a temporary variable. Any changes to SomeEvent after this point will not affect the copy you've made and stored. Thus you can now safely test whether any delegates were registered and subsequently invoke them.
Note that this solution solves one race problem, namely that of an event handler being null when it's invoked. It doesn't handle the problem where an event handler is defunct when it's invoked, or an event handler subscribes after the copy is taken.
For example, if an event handler depends on state that's destroyed as soon as the handler is un-subscribed, then this solution might invoke code that cannot run properly. See Eric Lippert's excellent blog entry for more details. Also, see this StackOverflow question and answers.
EDIT: If you're using C# 6.0, then Krzysztof's answer looks like a good way to go.
A: The recommended way is a little different and uses a temporary as follows:
EventHandler tmpEvent = SomeEvent;
if (tmpEvent != null)
{
tmpEvent();
}
A: Safer approach:
public class Test
{
private EventHandler myEvent;
private object eventLock = new object();
private void OnMyEvent()
{
EventHandler handler;
lock(this.eventLock)
{
handler = this.myEvent;
}
if (handler != null)
{
handler(this, EventArgs.Empty);
}
}
public event MyEvent
{
add
{
lock(this.eventLock)
{
this.myEvent += value;
}
}
remove
{
lock(this.eventLock)
{
this.myEvent -= value;
}
}
}
}
-bill
A: In C# 6.0 you can use monadic Null-conditional operator ?. to check for null and raise events in easy and thread-safe way.
SomeEvent?.Invoke(this, args);
It’s thread-safe because it evaluates the left-hand side only once, and keeps it in a temporary variable. You can read more here in part titled Null-conditional operators.
A: The simplest way remove this null check is to assign the eventhandler to an anonymous delegate. The penalty incurred in very little and relieves you of all the null checks, race conditions etc.
public event EventHandler SomeEvent = delegate {};
Related question: Is there a downside to adding an anonymous empty delegate on event declaration?
A: I would like to suggest an slight improvment to RoadWarrior's answer by
utilizing an extention function for the EventHandler:
public static class Extensions
{
public static void Raise(this EventHandler e, object sender, EventArgs args = null)
{
var e1 = e;
if (e1 != null)
{
if (args == null)
args = new EventArgs();
e1(sender, args);
}
}
}
With this extension in scope, events can be raised simply by:
class SomeClass
{
public event EventHandler MyEvent;
void SomeFunction()
{
// code ...
//---------------------------
MyEvent.Raise(this);
//---------------------------
}
}

1.setSupportActionBar(toolbar);
2.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
The snippet of code is:
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Comments");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
A: you can reach the app bar(action bar) via the toolbar . you make a toolbar and design it however you like then change the style of app to no action bar, then in code set you toolbar as actionbar. then your design toolbar will be the app bar
A: Just an example.
Use an Activity with this theme:
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
and this layout:
<androidx.coordinatorlayout.widget.CoordinatorLayout>
<com.google.android.material.appbar.MaterialToolbar
android:id="@+id/toolbar"/>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Then just use:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
It is the result. Just an empty Toolbar.
Add the setSupportActionBar(toolbar);
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
setSupportActionBar(findViewById(R.id.toolbar))
}
This method sets the toolbar as the app bar for the activity
Now add getSupportActionBar().setDisplayHomeAsUpEnabled(true);
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
setSupportActionBar(findViewById(R.id.toolbar))
supportActionBar.setDisplayHomeAsUpEnabled(true)
}
This method set whether home should be displayed as an "up" affordance

For example, if I open a simple webpage, open Inspect Element, and change things like text inside paragraphs and headings, the changes are immediately reflected on the webpage and stay as long as I don't reload the page.
Similarly, I tried to do some changes to the JavaScript code (Really simple code that does not connect to any server), but the changes did not take effect (What I did was edit the function a button activated so it did document.write() instead of displaying text in a blank paragraph element) I'm fairly sure this is possible to do, and I'm missing out on something.
I am fully aware I can just save the webpage and do whatever I want with it's code, but I'm just seeing if I can do it this way as well.
A: You can inject javascript methods via the console. That will have the same effect and will also allow you to copy / paste the new methods in fairly easily, instead of manually editing a JS file each time you refresh the page. As an example, open the console and paste the following in (on this page):
$('p').on('click', function(){alert("clicked paragraph")});
Now click on a paragraph and you will see the alert.
A: Of course, you can. Open "Sources" tab in your developer tools.
Then, find your file in the sources tree on the left side. Select a file, edit it and save it using Ctrl+S, Chrome will substitute the original file with yours.
You can also click {} icon in the bottom to prettify JS and make it easier to edit and debug.
Note that it works only with .js files. You cannot modify inline scripts using this approach.

That outputs this graph:
I need to find the closest points in Z that are being crossed by each of the lines. The idea is to integrate the values in Z that are crossed by the blue lines and plot that as a function of slope of the lines. Anyone has a good solution for it? I've tried a set of for loops, but I think it's kind of clunky.
Anyway, thanks for your time...
A: I am not sure about the closest points thing. That seems "clunky" too. What if it passes exactly in the middle between two points? Also I already had written code that weighs the four neighbor pixels by their closeness for an other project so I am going with that. Also I take the liberty of not rescaling the picture.
i,j = np.meshgrid(np.arange(41),np.arange(11))
Z = i*j + j
class Image_knn():
def fit(self, image):
self.image = image.astype('float')
def predict(self, x, y):
image = self.image
weights_x = [1-(x % 1), x % 1]
weights_y = [1-(y % 1), y % 1]
start_x = np.floor(x).astype('int')
start_y = np.floor(y).astype('int')
return sum([image[np.clip(np.floor(start_x + x), 0, image.shape[0]-1).astype('int'),
np.clip(np.floor(start_y + y), 0, image.shape[1]-1).astype('int')] * weights_x[x]*weights_y[y]
for x,y in itertools.product(range(2),range(2))])
And a little sanity check it returns the picture if we give it it's coordinates.
image_model = Image_knn()
image_model.fit(Z)
assert np.allclose(image_model.predict(*np.where(np.ones(Z.shape, dtype='bool'))).reshape((11,41)), Z)
I generate m=100 lines and scale the points on them so that they are evenly spaced. Here is a plot of every 10th of them.
n = 1000
m = 100
slopes = np.linspace(1e-10,10,m)
t, slope = np.meshgrid(np.linspace(0,1,n), slopes)
x_max, y_max = Z.shape[0]-1, Z.shape[1]-1
lines_x = t
lines_y = t*slope
scales = np.broadcast_to(np.stack([x_max/lines_x[:,-1], y_max/lines_y[:,-1]]).min(axis=0), (n,m)).T
lines_x *= scales
lines_y *= scales
And finally I can get the "points" consisting of slope and "integral" and draw it. You probably should take a closer look at the "integral" it's just a ruff guess of mine.
%%timeit
points = np.array([(slope, np.mean(image_model.predict(lines_x[i],lines_y[i]))
*np.linalg.norm(np.array((lines_x[i,-1],lines_y[i,-1]))))
for i,slope in enumerate(slopes)])
plt.scatter(points[:,0],points[:,1])
Notice the %%timeit in the last block. This takes ~38.3 ms on my machine and therefore wasn't optimized. As Donald Knuth puts it "premature optimization is the root of all evil". If you were to optimize this you would remove the for loop, shove all the coordinates for line points in the model at once by reshaping and reshaping back and then organize them with the slopes. But I saw no reason to put myself threw that for a few ms.
And finally we get a nice cusp as a reward. Notice that it makes sense that the maximum is at 4 since the diagonal is at a slope of 4 for our 40 by 10 picture. The intuition for the cusp is a bit harder to explain but I guess you probably have that already. For the length it comes down to the function (x,y) -> sqrt(x^2+y^2) having different directional differentials when going up and when going left on the rectangle.

Python has accuracy problems for large numbers, but if one simply rounds a logarithm to its floor, then it's possible to have a very simple implementation. I'd rather not code my own, so I'm looking for one.
As an example for Java, Guava implements a very fast log10 function when you want to round to floor.
A: If you only need to work with integers, there's always this slow-but-simple method:

return len("%d" % x) - 1

and similarly an IP Address as well?
Thank you
A: A MAC address is already in hexadecimal format, it is of the form of 6 pairs of 2 hexadecimal digits.
String macAddress = "AA:BB:CC:DD:EE:FF";
String[] macAddressParts = macAddress.split(":");
// convert hex string to byte values
Byte[] macAddressBytes = new Byte[6];
for(int i=0; i<6; i++){
Integer hex = Integer.parseInt(macAddressParts[i], 16);
macAddressBytes[i] = hex.byteValue();
}
And...
String ipAddress = "192.168.1.1";
String[] ipAddressParts = ipAddress.split("\\.");
// convert int string to byte values
Byte[] ipAddressBytes = new Byte[4];
for(int i=0; i<4; i++){
Integer integer = Integer.parseInt(ipAddressParts[i]);
ipAddressBytes[i] = integer.byteValue();
}
A: The open-source IPAddress Java library will parse both MAC addresses and IP addresses, and convert to bytes in a polymorphic manner. Disclaimer: I am the project manager of that library.
The following code will do what you are requesting:
String ipv4Addr = "1.2.3.4";
String ipv6Addr = "aaaa:bbbb:cccc:dddd::";
String macAddr = "a:b:c:d:e:f";
try {
HostIdentifierString addressStrings[] = {
new IPAddressString(ipv4Addr),
new IPAddressString(ipv6Addr),
new MACAddressString(macAddr)
};
Address addresses[] = new Address[addressStrings.length];
for(int i = 0; i < addressStrings.length; i++) {
addresses[i] = addressStrings[i].toAddress();//parse
}
for(Address addr : addresses) {
byte bytes[] = addr.getBytes();
//convert to a list of positive Integer for printing
List<Integer> forPrinting = IntStream.range(0, bytes.length).map(idx -> 0xff & bytes[idx]).boxed().collect(Collectors.toList());
System.out.println("bytes for " + addr + " are " + forPrinting);
}
} catch(HostIdentifierException | IOException e) {
//e.getMessage has validation error
}
output:
bytes for 1.2.3.4 are [1, 2, 3, 4]
bytes for aaaa:bbbb:cccc:dddd:: are [170, 170, 187, 187, 204, 204, 221, 221, 0, 0, 0, 0, 0, 0, 0, 0]
bytes for 0a:0b:0c:0d:0e:0f are [10, 11, 12, 13, 14, 15]

I have what looks to me like appropriate object registration:
For<ISomeInterface>().Use(() => GetConcreteInstance());
For<ISomeInterface>().MissingNamedInstanceIs.TheDefault();
For<ISomeOtherThing>().Add<OtherConcreteClass>()
.Ctor<ISomeInterface>().IsNamedInstance("Special");
However, if no "Special" instance of ISomeInterface is configured (which would typically occur in another Registry, if it needs to happen), then rather than falling back to the default instance (which is what I would expect) a call like this
[Container].GetAllInstances<ISomeOtherThing>();
results in the following: System.NotSupportedException: Instance's of type 'StructureMap.Pipeline.DefaultInstance' does not support ToNamedClose() and cannot be used as a MissingInstance
I'm guessing something is wrong in my registration... but what?
A: Based on a conversation with Jeremy Miller in StructureMap's Gitter IM channel, it seems as if this is an oversight in the current implementation, and is likely to be fixed shortly.
For anyone else needing it, the bug report can be found at https://github.com/structuremap/structuremap/issues/438

The problem is that the portrait pictures are displayed as landscape pictures, but zoomed in and clipped in half. Landscape pictures are also clipped to some extent, depending on window size.
How do I get colorbox to automatically scale all images so that the entire image fits nicely inside the window, disregarding the orientation or size?
See the illustration below for a demonstration of the problem.
A: Found a solution (though not optimal) thanks to Vitalii Masilianok tip about max-height
In the colorbox css I set:
#cboxContent img {
max-height: 100%;
}
And then I have to use the onComplete callback to resize the Colorbox:
$(".gallery").colorbox({
maxWidth: "95%",
maxHeight: "95%",
transition: "none",
onComplete: function() {
$.colorbox.resize({ width: $('.cboxPhoto').width() })
}
});
Using this solution I remove the transition, otherwise I get awkward sizeup-sizedown transitions between each slide.
A: Try this attitude:
*
*Compute the widthRatio as imageWidth / winWidth, heightRatio as imageHeight / winHeight
*Compute the ratio as Math.max(widthRatio, heightRatio)
*Set the image size to original imageWidth / ratio and original imageHeight / ratio
*Hook the function on window.load and window.resize
See this code
var image = document.getElementById("image");
var origWidth = image.offsetWidth, origHeight = image.offsetHeight;
function setImageSize() {
var winWidth = window.innerWidth, winHeight = window.innerHeight;
var ratioWidth = origWidth / winWidth, ratioHeight = origHeight / winHeight;
var ratio = Math.max(ratioWidth, ratioHeight);
// var ratio = Math.max(ratio,1); uncomment this not to enlarge small images
with(image.style) {
width = origWidth / ratio - 20 + "px"; // 10 px margin
height = origHeight / ratio - 10 + "px";
}
}
window.addEventListener("load",setImageSize);
window.addEventListener("resize",setImageSize);

You must register your channel definitions before Flex starts up.
So if registering it from a plugin won't work, where should I register it from? Where do I put this code?
const myChannel = Flex.DefaultTaskChannels.createChatTaskChannel("myChannel",
task => {
task.attributes.myAttribute = "test"
}
);
Flex.TaskChannels.register(myChannel);
A: I believe that what you are doing there is registering the TaskChannel in the Flex UI. However, you also need to create the TaskChannel definition in the "back-end" (TaskRouter).
This documentation on creating a TaskChannel via the TaskRouter API should be helpful: https://www.twilio.com/docs/taskrouter/api/task-channel#create-a-taskchannel

all cells textView's text is needed to convert form text to speech(TTS) on click UIButton.

A: The problem is that not all cells are visible during you click the button on one of them so while user enters text in the textView and scroll the text is lost so , so implement didEndDisplaying to store the current textView's text in the a global array and when cell button clicked loop through the array contents and do tts for every text

A: SMS actually uses the same API as other messages (like email). The key difference is that you want to pick the SMS account specifically, and you probably want to build is as part of a conversation.
Using the Message part of the BlackBerry PIM API, try something like this:
MessageService messageService;
AccountService accountService;
//Get the SMS/MMS account
QList<Account> accountList = accountService.accounts(Service::Messages,"sms-mms");
AccountKey accountId = accountList.first().id();
// Create a contact to whom you want to send sms/mms. Put the right phone number in yourself
int contactKey = -1;
MessageContact recipient = MessageContact(contactKey, MessageContact::To,"5555555555", "5555555555");
//Create a conversation because sms/mms chats most of the time is a conversation
ConversationBuilder* conversationBuilder = ConversationBuilder::create();
conversationBuilder->accountId(accountId);
QList<MessageContact> participants;
participants.append(recipient);
conversationBuilder->participants(participants);
Conversation conversation = *conversationBuilder;
ConversationKey conversationId = messageService.save(accountId, conversation);
//Create a message Builder for sms/mms
MessageBuilder* messageBuilder = MessageBuilder::create(accountId);
messageBuilder->addRecipient(recipient);
// SMS API's handle body as an attachment.
QString body = "body of the sms";
messageBuilder->addAttachment(Attachment("text/plain","body.txt",body));
messageBuilder->conversationId(conversationId);
Message message;
message = *messageBuilder;
//Sending SMS/MMS
MessageKey key = messageService.send(accountId, message);
qDebug() << "+++++++ Message sent" << endl;`

Table 1: StationStatus
Table 2: DetectorStatus
I can excecute a query as followed:
SELECT TOP 1000 [DetectorStatusID],
[DetectorID],
[DateTime],
[DetectorModeID],
NULL as StationModeID,
[Status]
FROM [GMS_MAN].[dbo].[DetectorStatus]
UNION SELECT TOP 1000 [StationStatusID],
[DetectorID],
[DateTime],
NULL as DetectorMOdeID,
[StationModeID],
[Status] FROM [GMS_MAN].[dbo].StationStatus
ORDER BY Status
Which will result in the 2 tables combined in 1.
However, I don't know how to do this in the code.
The query I'm currently executing is only for the DetectorStatus Table
[Query]
[OutputCache(OutputCacheLocation.Server, 60)]
public IQueryable<DetectorStatu> GetDatabacklog(int userID)
{
User user = ObjectContext.Users
.Include("TeamMemberships")
.First(u => u.UserID == userID);
var teamIDs = user.TeamMemberships.Select(t => t.TeamID).ToList();
var siteIDs = ObjectContext.SiteMemberships.Where(t => teamIDs.Contains(t.TeamID)).Select(t => t.SiteID).ToList();
var DetectorStatus = ObjectContext.DetectorStatus
.Include("Detector")
.Include("Detector.Track")
.Include("Detector.Site")
.Include("Detector.EnabledDetectorTypes")
.Include("Detector.EnabledDetectorTypes.DetectorType")
.Where(d => siteIDs.Contains(d.Detector.SiteID))
.OrderBy(d => d.Status);
return DetectorStatus;
}
And I call it like:
private void GetDatabacklog()
{
LoadOperation<DetectorStatu> loadOp = context.Load(context.GetDatabacklogQuery(App.CurrentUser.UserID), LoadBehavior.RefreshCurrent, LoadDatabacklogCompleted, null);
}
private void LoadDatabacklogCompleted(LoadOperation<DetectorStatu> loadOperation)
{
//The rest of the code where i show the results.
}
My question, how can I use this in multiple tables?
Because in the query I need to call StationStatu and DetectorStatu, however I don't know how to do this.
When I add .Union to anything, I get the following error:
The code I'm using:
var detectorSt = ObjectContext.DetectorStatus.Select(x => new { x.DetectorID, x.Status});
var stationSt = ObjectContext.StationStatus.Select(x => new { x.DetectorID, x.Status});
var unioned = detectorSt.Union(stationSt);
return unioned;
A: I can't see any reason to query the data from two tables in a single query, without linking the results in any way. So I suggest you query the tables separately, select them into a common data object and merge them in client rather than server side (you can still sort the queries on server if you want, then just merge sorted data in client).
public class StatusTransferObject
{
public int DetectorId { get; set; }
public DateTimeOffset DateTime { get; set; }
public int? DetectorModeId { get; set; }
public int? StationModeId { get; set; }
public decimal Status { get; set; }
}
var orderedObjects1 = ObjectContext.DetectorStatus.OrderBy(s => s.Status).Select(s => new StatusTransferObject
{
DetectorId = s.DetectorID,
DateTime = s.DateTime,
DetectorModeId = s.DetectorModeID,
StationModeId = null,
Status = s.Status
});
var orderedObjects2 = ObjectContext.StationStatus.OrderBy(s => s.Status).Select(s => new StatusTransferObject
{
DetectorId = s.DetectorID,
DateTime = s.DateTime,
DetectorModeId = null,
StationModeId = s.StationModeID,
Status = s.Status
});
var mergedObjects = MergeSorted(orderedObjects1, orderedObjects2, (x1, x2) => x1.Status.CompareTo(x2.Status)).ToList();
MergeSorted is taken from the following question: Is there an easy way to merge two ordered sequences using LINQ?

I have an instance of MyType1, arg, passed in as an argument to a method. If arg is an instance of MyType2, then I'd like to perform some logic, transforming the instance. My code looks something like the code below.
Having to create a new local variable b feels inelegant - is there a way of achieving the same behavior without the additional local variable?
public MyType1 MyMethod(MyType1 arg)
{
if(arg is MyType2)
{
MyType2 b = arg as MyType2;
//use b (which modifies "arg" as "b" is a reference to it)...
}
return arg;
}
A: Note that the "is" and "as" is duplicating the test; either use is and then (once you know) just cast - or use as in the first place and test for null.
Re your issue; if you only want to do one thing - then cast:
if(arg is MyType2)
{
((MyType2)arg).SomeSpecialMethod();
}
Otherwise - perhaps a virtual method (on the base-type), or just refactor the logic out into another method, so you have:
if(arg is MyType2)
{
StuffThatTakesType2((MyType2)arg);
}
But persoanlly, I'd just use the extra variable:
MyType2 whatever = arg as MyType2;
if(whatever != null) {
whatever.Foo = 123;
whatever.Bar();
}
A: No; you need to create a separate variable.
Also, your code performs more casts than necessary; it would be a little bit faster like this:
MyType2 b = arg as MyType2;
if(b != null)
{
//Use b
}
A: I would say option 1 is to put all the modifying code (your comment line) as a function of MyType2, and then do (arg as MyType2).Foo() on it.
Option 2 is to implement MyMethod on both MyType1 and as an override in MyType2, and just call it without worrying. The MyType1 implementation may do nothing, which isn't the best design.
edit: technically not a violation of LSP since that only applies in the reverse of this situation (MyType2 shouldn't break behavior of MyType1).

[0]; Could not resolve type id 'console' into a subtype of [simple type, class io.dropwizard.logging.AppenderFactory]: known type ids = [AppenderFactory]
Here is the snippet of my .yml file:
logging:
appenders:
- type: console
timeZone: UTC
logFormat: '%-5level [%date{ISO8601}] [%X{requestId}] %c: %msg%n%rootException'
I was able to find posts about similar issues. For instance, this thread here suggests to check if file META-INF/services/io.dropwizard.logging.AppenderFactory is in the application jar and if it contents is as following:
io.dropwizard.logging.ConsoleAppenderFactory
io.dropwizard.logging.FileAppenderFactory
io.dropwizard.logging.SyslogAppenderFactory
I have verified it. In my case file is where it supposed to be and it has exactly the same contents.
Any help will be greatly appreciated.
Dropwizard version 0.9.2
A: Does the Gradle produce a Uber/Fat Jar (A jar with all it's dependencies inside itself) or a simple jar with only your Dropwizard app?
It's advisable to build an Fat-jar for Dropwizard deployments, so do switch over to this style if you're not doing so.
Now while building a Fat-Jar, you need to do the following to solve your problem (this was mentioned in the discussion you linked)
If you use maven-shade plugin for building a fat jar, don't forget about SPI resource transformer for collecting SPI resources into the jar.
<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
To do the same in Gradle, check this discussion.

I'm working with code that attempts to sort by that value but unfortunately, since it's a string, I get the unsurprising behavior that "10" comes before "2". I do not have license to change the data in the table, so I'm looking for a way to write the order so that it orders by the value as an integer rather than as the string it naturally is.
Here is some toy SQL to hopefully better show what I'm asking:
INSERT INTO hstore_test (sale)
VALUES ('"milk"=>"4",
"bread"=>"2",
"bananas"=>"12",
"cereal"=>"1"');
Now at this point I want to get all the things, sorted by milk -> value:
SELECT * FROM hstore_test ORDER BY sale -> 'milk';
This unfortunately sorts by the string value of milk ("4" in the example above).
I've been kind of envisioning something like
SELECT * FROM hstore_test ORDER BY CAST(sale -> 'milk' as INT);
but I can't convince myself that's correct.

In this case in the diagram, I'm relating a TeamMember via TeamMemberGUID in a many to many setup via the ObjectTag junction table a 'la the ObjectGUID field. I could just as easily relate any other GUID keyed entity in the same way. Thus I have a central repo of tags that can "tag" various entities. Pretty slick, or so I thought.
The trouble is I can't seem to find a way to bring this data back with LINQ to Entities. I'm using EF Code First and I want to bring this back in one query if possible. The closest I've gotten is using ugly outer join syntax:
var team = from tm in db.TeamMembers
join ot in db.ObjectTags on tm.TeamMemberGuid equals ot.ObjectGuid into objTags // outer join to ObjectTag
from ot2 in objTags.DefaultIfEmpty()
join tags in db.Tags on ot2.TagId equals tags.TagId into tmTags // join via ObjectTag to Tag
select new TeamMemberDTO
{
TeamMember = tm,
Tags = tmTags
};
But this gives me a flattened set (4 team members sharing 2 tags can equal up to 8 results) where what I'm looking for is a hierarchical TeamMember object with a Tags property of the associated tags.
I've tried normal relation properties but EF doesn't want to map more than one entity to a junction table so that's out. I've also tried a group by but haven't gotten far with that.
Is this out for LINQ to EF? Do I need to consider a view or something?
Really hoping an EF pro can help me on this one. I feel like I'm missing something or taking the wrong approach.

CustomerID Itemset
1 1
1 3

... ...
I want to write this table in Datatable 'Matrix' where the Rows are Itemset={1,2,3,4,5,6....,k} and Columns are CustomerID={1,2,3,4,...,x}
and the rows are 1 if the 'Itemset' belongs to the CustomerID.
The output I want is like..
1 2 3 4 5 6 7 ............. x
1 1 0 1 0 0 0 1 0 0 0 0 0 0 0 0
2 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0
3 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0
4
5
6 /And so on!
7

9
`
I tried to code it but the problem is in VS Parameters for SQL Query don't work with Loops.
This is my code-
objConnection.Open()
Dim matrix As DataTable = New DataTable("Retail")
intcount = 0
For intcount = 1 To noofCustomerID_col
matrix.Columns.Add(intcount, GetType(Integer))
Next
Dim i As Integer
Dim workRow As DataRow
Dim Boolin As Boolean
For i = 1 To 9
ObjCommand.CommandText = "Select count(*) from Retail Where CustomerID=@in and Itemset=@in"
ObjCommand.Parameters.AddWithValue("@in", i) {{I Get Error here as I can't Loop Parameters}}
Boolin = ObjCommand.ExecuteScalar()
workRow = matrix.NewRow()
workRow(0) = i
workRow(1) = Boolin
matrix.Rows.Add(workRow)
Next
Kindly Help. I know this code can completely be wrong and it's okay if you can suggest totally different way of doing it. I've been stuck for quite some time now! Thanks.
If any clarification is needed I shall explain as many times needed in the comments.
A: Like Tab Alleman suggested, SQL PIVOT can come handy here.
Dynamic SQL is also needed.
DECLARE @DynamicColumn NVARCHAR(MAX),
@DynamicQuery NVARCHAR(MAX)
SELECT @DynamicColumn = SELECT '[' + CONVERT(NVARCHAR, CustomerID) + '],'
FROM Retail AS Customer
ORDER BY CustomerID
FOR XML PATH('')
SELECT @DynamicColumn = SUBSTRING(@DynamicColumn, 0, DATALENGTH(@DynamicColumn) / 2)--REMOVE EXTRA ","
SELECT @DynamicQuery = 'SELECT *
FROM ( SELECT CustomerID,
ItemSet
FROM Retail) AS D
PIVOT
(
COUNT([CustomerID])
FOR Itemset IN (' + @DynamicQuery + ')
) AS P'
EXECUTE(@DynamicQuery)

I found that probably <to uri="log:ProcessSyncOperation?level=DEBUG&showHeaders=true" /> line cause error.
Is it possible to workaround this problem? (I know that I can delete this log but maybe there is other options)

A: You'll need to use the $sce service Strict Contextual Escaping.
Add this service in your controller declaration, like this:
controller('sampleController', ['$scope', '$http', '$sce', function($scope, $http, $sce) {
Now you must define a function that will only inject a span tag with a CSS class name with the yellow color to highlight, when the searched text is found, through the $sce.trustAsHtml method, to indicate AngularJS, the injected is safe content.
$scope.highlightText = function(text, search) {
if (search && search.length === 0) {
// Returns the default content.
return $sce.trustAsHtml(text);
}
// Define a regular expression to find the text globally and ignoring capital letters.
var regex = new RegExp(search, 'gi');
// If you already found the text then inject a span element with CSS class to highlight that you found.
return $sce.trustAsHtml(text.replace(regex, '<span class="foundText">$&</span>'));
};
In the previous regular expression replacement text, $& indicates to display the captured text that matches the regular expression within the replaced.
In the HTML, within the ng-repeat, add the ngBindHtml directive with highlightText function where the first parameter is the text that you'll have to search and the second parameter is the text to find.
In your case, in this way:
<tr ng-repeat="user in users | filter:searchFilter">
<td style="border: 1px solid black ; width:30%;white-space: pre-wrap;" ng-bind-html="highlightText(user.gsx$topic.$t, search)">{{user.gsx$topic.$t}}</td>
See in this example:
angular.module('sample', []).
controller('sampleController', ['$scope', '$http', '$sce', function($scope, $http, $sce) {
var url = "https://spreadsheets.google.com/feeds/list/153Obe1TdWlIPyveZoNxEw53rdrghHsiWU9l-WgGwCrE/od6/public/values?alt=json";
$http.get(url)
.success(function(data, status, headers, config) {
$scope.users = data.feed.entry;
console.log($scope.users);
})
.error(function(error, status, headers, config) {
console.log(status);
console.log("Error occured");
});
$scope.search = '';
$scope.searchFilter = function(item) {
if (item.gsx$topic.$t.indexOf($scope.search) != -1 || item.gsx$response.$t.indexOf($scope.search) != -1) {
return true;
}
return false;
};
$scope.highlightText = function(text, search) {
if (search && search.length === 0) {
// Returns the default content.
return $sce.trustAsHtml(text);
}
// Define a regular expression to find the text globally and ignoring capital letters.
var regex = new RegExp(search, 'gi');
// If you already found the text then inject a span element with CSS class to highlight that you found.
return $sce.trustAsHtml(text.replace(regex, '<span class="foundText">$&</span>'));
};
}]);
.foundText {
background-color: #ff0;
color: #f00;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.0/angular.min.js"></script>
<div ng-app="sample" ng-controller="sampleController">

Hope this helps!
A: You can add <span> with highlighted class. Make sure to create a deep copy of the original array. I used JSON.parse(JSON.stringify(...)). In addition, since we are adding the <span> and want to display it as html, we need to use ng-bind-html. In order to do that, we need to add ngSanitize as module dependency.
angular.module('myApp', ['ngSanitize'])
.controller('myController', ['$scope', ($scope) => {
const content = [{
question: 'Question 1',
answer: 'Answer 1'
},
{
question: 'Question 2',
answer: 'Answer 2'
}
];
//create copy of the original array
$scope.filteredContent = JSON.parse(JSON.stringify(content));
$scope.highlight = () => {
//create copy of the original array
$scope.filteredContent = JSON.parse(JSON.stringify(content));
$scope.filteredContent.forEach(fc => {
const regEx = new RegExp($scope.searchText);
fc.question = fc.question.replace(regEx, `<span class="highlight">${$scope.searchText}</span>`);
fc.answer = fc.answer.replace(regEx, `<span class="highlight">${$scope.searchText}</span>`);
});
};
}]);
table {
border-collapse: collapse;
margin-top: 10px;
border: 1pt solid black;
width: 100%;

padding: 0;

import matplotlib.pyplot as plt
import collections as col
import numpy as np
class Graph(object):
"""Single 2-D dynamic plot. The axes must be same length and
have both minimum and maximum possible values.
"""
def __init__(self, window, subplot_num, x_axis, y_axis):
ax = window.add_subplot(subplot_num)
self.y, = ax.plot(x_axis, # Obtain handle to y axis.
y_axis,
marker='^'
)
self.y_data = col.deque(y_axis, # Circular buffer.
maxlen=len(y_axis)
)
# Make plot prettier
plt.grid(True)
plt.tight_layout()
def add_datapoint(self, y):
self.y_data.appendleft(y) # Remember - circular buffer.
self.y.set_ydata(self.y_data)
I am passing to x_axis range(60) to set the static horizontal axis. y_axis is getting range(10, 60) in order to set it's range.
From then on, I listen to stdin and add a new point each second.
The problem is, that the inital graph is hidious:
I want to remove the initial diagonal line. I tried initializing y_axis with NaNs and calling ax.set_yrange(), but that doesn't do what I am opting for. I also tried not passing y values, but mpl.plot wants x and y axes of equal length.
How can I remove the initial diagonal line? I am ok both with manually setting y range or the graph resizing dynamically as new data arrives.

My show.blade.php
@section('content')
<p>This is user {{ $profile->name }}</p>
<p>This is address {{ $profile->address }}</p>
<img src= "/storage/images/{{ $profile->images }}" style="width:504px;height:228px />
@endsection
this works fine.
now edit.blade.php
<div class="container">
<form method="POST" action="/profiles/{{$profile->id}}" enctype="multipart/form-data">
{{ method_field('PATCH') }}
{{ csrf_field() }}
<div class="form-group">
name <input type="text" name="name" value="{{ $profile->name }}" />
</div>
<div class="form-group">
address <input type="textarea" name="address" value="{{ $profile->address }}" />
</div>
<div class="form-group">
@if ("/storage/images/{{ $profile->images }}")
<img src="{{ $profile->image }}">
@else
<p>No image found</p>
@endif
image <input type="file" name="image" value="{{ $profile->images }}"/>
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary">Submit</button>
</div>``
</div>
when I try to save the form a diffrent images path is saved in database table when updating the images ie
/tmp/phpHs0Io6
store controller is
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required|max:255',
'address' => 'nullable' ,
]);
$profile = new profile;
$profile-> user_id = auth()->id();
$profile-> name = $request->name;
$profile-> address = $request->address;
$request->image->store('public/images');
$path = $request->image->hashName();
$profile-> images = $path;
$profile->save();
return redirect('/home');
}
and update controller is
public function update(Request $request, profile $profile)
{
$this->validate($request, [
'name' => 'required|max:255',
'address' => 'nullable' ,
]);
$profile->update($request->all());
$profile-> name = $request->name;
$profile-> address = $request->address;
$request->image->store('public/images');
$path = $request->image->hashName();
$profile-> images = $path;
$profile->save();
return redirect('/home');
}
A: First of all before you save an image you have to check if user uploaded one; Your way of saving image is wrong use this pattern;
public function update(Request $request, profile $profile)
{
$this->validate($request, [
'name' => 'required|max:255',
'address' => 'nullable' ,
]);
$profile->update($request->all());
$profile-> name = $request->name;
$profile-> address = $request->address;
if(Input::hasFile('image')){
$file = Input::file('image');
$destinationPath = public_path(). '/uploads/';
$filename = $file->getClientOriginalName();
$file->move($destinationPath, $filename);
//then proceeded to save user
$profile-> images =
$destinationPath.$filename;
$profile->save();
return redirect('/home');
}else{
$profile->save();
return redirect('/home');
}
}
same on update function.
A: Instead of directly writing path in if condition, use file_exists function to check whether your image exist at the given location. For more info check this link
A: i am a bit late but i have a suggestion:
so if ur image is being uploaded in storage this code might work, u still need to resize image so its not over the whole site:
<div class="pull-right">
<label for="image">Choosen Datei:</label>
<img src="{{Storage::disk('local')->url($profile->image)}}" alt="">
<label for="image"
>Choose data</label
>
<input
type="file"
name="image"
id="image"
class="form-control"
/>
</div>
