I\'m already familiar with repeating tasks every n seconds by using Java.util.Timer and Java.util.TimerTask. But lets say I want to print \"Hello World\" to the console every random seconds from 1-5. Unfortunately I\'m in a bit of a rush and don\'t have any code to show so far. Any help would be apriciated.

The question is very simple, but I just could not find the answer!

\n\n

Why doesn\'t

\n\n
return x == 0? \"\" : \"Hello\"\n
\n\n

compile but

\n\n
return x == 0 ? \"\" : \"Hello\"\n
\n\n

does?

\n\n

This is really weird because all the other operators don\'t need an extra white space. e.g.

\n\n
let x = 1+1\nlet y = 1 + 1\n
\n\n

are the same.

\n\n

I think it has something to do with optionals. But when you use a ? operator on a variable, it must be used like this:

\n\n
let s: String? = nil\nlet x = s?.startIndex\n
\n\n

I mean it must follow another operator, right?

\n',,'01/01/2016 17:21',HQ 34558390,'Why does the reverse() function in the Swift standard library return ReverseRandomAccessCollection?','

Now that I\'ve learned Swift (to a reasonable level) I\'m trying to get to grips with the standard library, but in truth it\'s mainly ελληνικά to me!

\n\n

So a specific question: I have an array of strings and I can call reverse() on it.

\n\n
let arr = [\"Mykonos\", \"Rhodes\", \"Naxos\"].reverse()\n
\n\n

Now naively I thought I\'d get back a type of Array from this. (Ruby for example has a similar method that you pass an array and get back an array)

\n\n

But arr is now actually of type

\n\n
ReverseRandomAccessCollection<Array<String>>\n
\n\n

which is actually a struct, which conforms to CollectionType:

\n\n
public struct ReverseRandomAccessCollection<Base : CollectionType where Base.Index : RandomAccessIndexType> : _ReverseCollectionType\n
\n\n

This means I can do this:

\n\n
for item in arr {\n  print(item)\n}\n
\n\n

but I can\'t do

\n\n
print(arr[0])\n
\n\n

Why is this designed to be this way?

\n\n

Dictionaries in Swift also implement CollectionType, so I can do this:

\n\n
let dict = [\"greek\" : \"swift sometimes\", \"notgreek\" : \"ruby for this example\"].reverse()\n
\n\n

But dictionaries are not ordered like arrays, so why can I call reverse() on dicts?

\n\n

Bonus points if anyone can point me in the direction of where I can read up and improve my Swift stdlib foo, Ευχαριστώ!

var text: NSString = \"\"\n

with

\n\n
let text: NSString\n

I get an All stored properties of a class instance must be initialized before throwing from an initializer error.

I want to create a bigger Floating Action Button (FAB), more than the usual 56 dp, with a bigger icon inside.\n(For my purpose an icon will never be self-explanatory so I will create a png-file containing a short text and use this png as icon.)

\n\n

Increasing the size of the FAB works fine:
\nas i don\'t use the mini-FloatingActionButton, i redefined the mini-button-size.
\nin my layout-xml i specify:

\n\n
<android.support.design.widget.FloatingActionButton\n    ...\n    app:fabSize=\"mini\"\n    ....\n
\n\n

and in the dimensions.xml i redefine the size for the mini-fab:

\n\n
<dimen name=\"fab_size_mini\">80dp</dimen>\n
\n\n

However, I didn\'t manage to get a bigger icon on the FAB.\nI tried icons with different dp\'s from the material icons library - no success. Also setting a padding on the FAB-layout did not work.

I would like to run a process in a thread (which is iterating over a large database table). While the thread is running, I just want the program to wait. If that thread takes longer then 30 seconds, I want to kill the thread and do something else. By killing the thread, I mean that I want it to cease activity and release resources gracefully.

\n\n

I figured the best way to do this was through a Thread()\'s join(delay) and is_alive() functions, and an Event. Using the join(delay) I can have my program wait 30 seconds for the thread to finish, and by using the is_alive() function I can determine if the thread has finished its work. If it hasn\'t finished its work, the event is set, and the thread knows to stop working at that point.

\n\n

Is this approach valid, and is this the most pythonic way to go about my problem statement?

\n\n

Here is some sample code:

\n\n

When I use a prototype table view, I always have to conform to the protocol TableViewDataSource. I always forget what methods I need to implement, so I have to look at the source of the protocol every time. This is really time consuming.

I think Xcode must have a feature that automatically implements the needed methods for you, right? Just like IntelliJ IDEA, Eclipse, and Visual Studio.

\n\n

I want to know where can I find this feature. If there\'s isn\'t, is there a workaround for this? At least I don\'t have to open the source code of the protocol each time I conform to it.

If you don\'t understand what I mean, here\'s some code:

\n\n

I have a protocol

\n\n
protocol Hello {\n    func doStuff ()\n}\n

When I conform to it,

\n\n
class MyClass: Hello {\n\n}\n

I often don\'t remember the names of the methods that I need to implement. If Xcode has a feature that turns the above code, into this:

\n\n
class MyClass: Hello {\n    func doStuff () {\n        code\n    }\n}\n

I want to be able to detect if a mongo server is available from the java driver for the purpose of reacting to any abnormal events as one would in JDBC land etc. It all works fine when the server is up but I am struggling to understand why it is so difficult to detect errors. I have a feeling its because the mongo client runs in a different thread and it doesn\'t re throw to me or something?

\n\n
try {\n        MongoClient mongoClient = new MongoClient(\"localhost\", 27017);\n        MongoDatabase db = mongoClient.getDatabase(\"mydb\");\n        // if db is down or error getting people collection handle it in catch block\n        MongoCollection<Document> people = commentarr.getCollection(\"people\");\n    } catch (Exception e) {\n        // handle server down or failed query here.\n    }\n
\n\n

The result is

\n\n
INFO: Exception in monitor thread while connecting to server localhost:27017\n
\n\n

With the resulting stack trace containing a few different exceptions which I have tried to catch but my catch blocks still didn\'t do anything.

\n\n
com.mongodb.MongoSocketOpenException: Exception opening socket\nCaused by: java.net.ConnectException: Connection refused\n
\n\n

I am using the java mongodb driver 3.0.4, most posts I read are from an older API with hacks like MongoClient.getDatabaseNames() which throws a MongoException if errors, except this is deprecated now and replaced with MongoClient.listDatabaseNames() which doesn\'t have the same error throwing semantics.

\n\n

Is there a way to just execute a mongo query from the java driver in a try catch block and actually have the exception caught?

To give a little context to my issue...

\n\n

I have a Java EE web application (as a UI / client) that accesses services for data / business logic via a REST interface using the JAX-RS 2.0 client API (Resteasy implementation).

\n\n

Currently I inject a new JAXRS Client instance per request using a RequestScoped CDI managed bean, the thinking being that the client app may call multiple backend resources per request and I reuse the same JAXRS Client for the whole request (although I read somewhere this may not be correct as I am potentially changing the URI for each invocation)

\n\n

The documentation for JAXRS Client seems to suggest that the client is a potentially expensive operation and the app should limit the amount of connections it creates. It also seems to contradict itself and suggest the client should be closed once all the requests to a particular WebTarget are finished.

\n\n

The client application could potentially support thousands of simultaneous users so creating and destroying thousands of \'expensive clients\' does not seem to be the correct approach so am thinking a shared client pool is more appropriate but there doesn\'t seem to be any information on how this should be achieved.

\n\n

All examples appear to show creating a new client for the request and a) closing it after or b) not closing it but not really explaining what happens on a second request.

\n\n

Can you help provide some answers on how you think this would be solved or information on what the best practice for this approach is.

Thanks.

Let\'s say you have the repository:

\n\n
myCode/megaProject/moduleA\nmyCode/megaProject/moduleB\n
\n\n

Over time (months), you re-organise the project. Refactoring the code to make the modules independent. Files in the megaProject directory get moved into their own directories. Emphasis on move - the history of these files is preserved.

\n\n
myCode/megaProject\nmyCode/moduleA\nmyCode/moduleB\n
\n\n

Now you wish to move these modules to their own GIT repos. Leaving the original with just megaProject on its own.

\n\n
myCode/megaProject\nnewRepoA/moduleA\nnewRepoB/moduleB\n
\n\n

The filter-branch command is documentated to do this but it doesn\'t follow history when files were moved outside of the target directory. So the history begins when the files were moved into their new directory, not the history the files had then they lived in the old megaProject directory.

How to split a GIT history based on a target directory, and, follow history outside of this path - leaving only commit history related to these files and nothing else?

I am new to web development and I have just started building an Angular 2 app. At this point I am trying to create some CRUD components/forms but I find my self duplicating a lot of code. I am not going to ask what are the common best practices to avoid code duplication and achieve component reusability when designing CRUD applications with Angular2, because the post will get locked. I will rather focus on one particular aspect:

\n\n

I have a \"CRUD page\" that has a list (it is an html table actually) of resources and several buttons that open up \"create\", \"read\", and \"edit\" forms. The list is a separate component on its own and the create/read/edit separate components as well. Each row of the table includes another component which knows how to render a resource item. I will call this <resource-item> component. However, I have several of those \"CRUD pages\", each page for a different resource. So what I want is to reuse the list component for all the resources. So the first thing to do is to add Inputs or Attributes to the list component in order to control its labels. So far so good.

\n\n

But what about the <resource-item> component? Each resource of my application might have a completely different structure. As a result I will need different components for different resources, e.g.: <resource-a-item>, <resource-b-item>, etc. How can I specify which resource item component I want to use every time I create a list component?

  4. Step 2 also meant I needed to run the following commands in the psql command prompt: grant usage on schema public to public;\ngrant create on schema public to public;

I\'m using NodeJS with Express, and when I use foreign characters in the URL, they automatically get encoded.

How do I decode it back to the original string?

So the string: אובמה

I\'ve been trying to make a stopwatch in react and redux. I\'ve been having trouble trouble figuring out how to design such a thing in redux.

\n\n

The first thing that came to mind was having a START_TIMER action which would set the initial offset value. Right after that, I use setInterval to fire off a TICK action over and over again that calculates how much time has passed by using the offset, adds it to the current time, and then updates the offset.

\n\n

This approach seems to work, but I\'m not sure how I would clear the interval to stop it. Also, it seems like this design is poor and there is probably a better way to do it.

\n\n

Here is a full JSFiddle that has the START_TIMER functionality working. If you just want to see what my reducer looks like right now, here it is:

\n\n
const initialState = {\n  isOn: false,\n  time: 0\n};\n\nconst timer = (state = initialState, action) => {\n  switch (action.type) {\n    case \'START_TIMER\':\n      return {\n        ...state,\n        isOn: true,\n        offset: action.offset\n      };\n\n    case \'STOP_TIMER\':\n      return {\n        ...state,\n        isOn: false\n      };\n\n    case \'TICK\':\n      return {\n        ...state,\n        time: state.time + (action.time - state.offset),\n        offset: action.time\n      };\n\n    default: \n      return state;\n  }\n}\n

On Laravel i have configured CORS like this :

\n\n
public function handle($request, Closure $next)\n{\n    header(\"Access-Control-Allow-Origin: http://localhost:8001/\");\n\n    // ALLOW OPTIONS METHOD\n    $headers = [\n        \'Access-Control-Allow-Methods\'=> \'POST, GET, OPTIONS, PUT, DELETE\',\n        \'Access-Control-Allow-Headers\'=> \'Content-Type, X-Auth-Token, Origin\'\n    ];\n    if($request->getMethod() == \"OPTIONS\") {\n        // The client-side application can set only headers allowed in Access-Control-Allow-Headers\n        return Response::make(\'OK\', 200, $headers);\n    }\n\n    $response = $next($request);\n    foreach($headers as $key => $value)\n        $response->header($key, $value);\n    return $response;\n}\n
\n\n

The Normal cross domain POST request works fine. i.e $http.post(). I have tried many different variations of headers on angular but none helps. Also the OPTIONS request returns 200 OK but still preflight response failure message is displayed. Can anyone help me with how to further debug this issue?

I\'m looking to convert the MIN_SAFE_INTEGER through MAX_SAFE_INTEGER range of a JavaScript number (53-bits not including the sign) into a string of bits spread over 7 bytes shifted two to allow for sign and null identifiers.

Thus far the best I\'ve come up with is:

\n\n
function toUint8Array(data) {\n    data = data.toString(2);\n    data = new Array(65 - data.length).join(\'0\') + data;\n    var ret = new Uint8Array(data.length / 8);\n    for (var i = 0; i < 8; i++) {\n        ret[i] = 0;\n        ret[i] += (data[i * 8] == \'1\' ? 128 : 0);\n        ret[i] += (data[(i * 8) + 1] == \'1\' ? 64 : 0);\n        ret[i] += (data[(i * 8) + 2] == \'1\' ? 32 : 0);\n        ret[i] += (data[(i * 8) + 3] == \'1\' ? 16 : 0);\n        ret[i] += (data[(i * 8) + 4] == \'1\' ? 8 : 0);\n        ret[i] += (data[(i * 8) + 5] == \'1\' ? 4 : 0);\n        ret[i] += (data[(i * 8) + 6] == \'1\' ? 2 : 0);\n        ret[i] += (data[(i * 8) + 7] == \'1\' ? 1 : 0);\n    }\n    return (ret);\n}\n

Fiddle

As you can tell right off, this would be abominably slow (and the bits still haven\'t been shifted two places across all 7 active bytes.)

These two sets of letters are calculated and weaved back together to form one decrypted string.

This is a very simple, dummy example. I\'m having some issue matching dates in Pandas and I can\'t figure out why.

\n\n

Say I want to match row 1 in the above df.
\nI know beforehand that I want to match ID 1.
\nAnd I know the date I want as well, and as a matter of fact, I\'ll extract that date directly from row 1 of the df to make it bulletproof.

some_id = 1\nsome_date = df.iloc[1:2][\'Date\']  # gives 2016-01-01\n

So why doesn\'t this line work to return me row 1??

df[(df[\'ID\']==some_id) & (df[\'Date\'] == some_date)] \n

\n\n

I need to make simple thing. Make an input on a website, and under it, make a <p> tag. Whatever user inputs to this label/input, it will write that between the <p> tag. I know, that there is way in javascript, but i need to make it change forever, that means, when i refresh the page, it will be there, the same message forever. Any way to make it? Better to make it NOT using cross-database systém (in PhP)...

\n\n

Please help

There is an article Optimization killers in wiki of Bluebird library. In this article there is a phrase:

\n\n
\n

Currently not optimizable:
\n ...
\n Functions that contain a compound let assignment
\n Functions that contain a compound const assignment

\n
\n\n

What does compound let assignment and compound const assignment mean?\nIn ECMAScript 5.1 there was notion of compound assignment but in ECMAScript 2015, it seems there is no notion of any compound assignment there is only regular assignments.

\n\n

I suspect that compound let and const assignment, it is just compound assignment after declaration. For example:

\n\n
let n = 1;\nn += 4;\n
\n\n

Am I right?

This is the default configuration I want for working on personal projects, open source stuff, etc.

git clone ssh://git@git.mycorp.com:1234/groupA/projectA.git\ncd projectA\ngit config user.email \"mkobit@mycorp.com\"\ngit config user.name \"m.kobit\"\n

git config --global alias.clonecorp \'clone \\ \n        -c user.name=\"m.kobit\" -c user.email=\"mkobit@mycorp.com\"\'\ngit clonecorp ssh://git@git.mycorp.com:1234/groupA/projectA.git\n

Both of these can be error prone because they both depend on me being smart and following the right steps. Evidence shows that this is near-guaranteed for me to screw-up sometime.

What I intend to do is to merge it into weekly-based data. After grouping:

\n\n
    \n
  1. the Date should be every Monday (at this point, holidays scenario should be considered when Monday is not a trading day, we should apply the first trading day in current week as the Date).
    2. \n
  2. Open should be Monday\'s (or the first trading day of current week) Open.
    3. \n
  3. Close should be Friday\'s (or the last trading day of current week) Close.
    4. \n
  4. High should be the highest High of trading days in current week.
    5. \n
  5. Low should be the lowest Low of trading days in current week.
    6. \n
  6. Volumn should be the sum of all Volumes of trading days in current week.
    7. \n

which should look like this:

I don\'t mind working with scss instead of sass, but I find it weird. Because it made sass files for me etc.. and now it\'s wanting me to use scss.

\n\n

Does anyone know how I would maybe be able to use sass instead of scss?

I\'m looking for this for a long time.

I need to extract and get modulus and exponent from SSH server.

\n\n

For example, I know, that on server xxx.xxx.xxx.xxx is running ssh (I can connect to this server / ping) but I dont know user name and password so cannot log in.

I need to get modulus and exponent of public RSA key of this server.

I found, that ssh-keyscan can get modulus + exponent (from documentation) but only if ssh-rsa1 is used. If I try to get ssh-rsa(2) public key with ssh-keyscan, I cannot retrieve from output modulus and exponent.

I have noticed a bit of switching between using const and import for referencing libraries in node.js applications using es6 syntax with Babel.

\n\n

What is the preferred method and what is the difference between using const and import? Assuming you may be importing the same library in many files/components.

\n\n

const

\n\n
const React = require(\'react\')\n
\n\n

import

\n\n
import React from \'react\'\n
\n\n

Here are the definitions of each but I am still not sure which to use.

\n\n

import

\n\n

The import statement is used to import functions, objects or primitives that have been exported from an external module, another script, etc.

\n\n

const

\n\n

The const declaration creates a read-only reference to a value. It does not mean the value it holds is immutable, just that the variable identifier cannot be reassigned.

\n',,'05/01/2016 02:40',HQ 34603388,'Should Comparable ever compare to another type?','

I\'m wondering if there\'s ever a valid use case for the following:

\n\n
class Base {}\n\nclass A implements Comparable<Base> {\n    //...\n}\n
\n\n

It seems to be a common pattern (see Collections for a number of examples) to accept a collection of type T, where T extends Comparable<? super T>.

\n\n

But it seems technically impossible to fulfill the contract of compareTo() when comparing to a base class, because there\'s no way to ensure that another class doesn\'t extend the base with a contradictory comparison. Consider the following example:

\n\n
class Base {\n    final int foo;\n    Base(int foo) {\n        this.foo = foo;\n    }\n}\n\nclass A extends Base implements Comparable<Base> {\n    A(int foo) {\n        super(foo);\n    }\n    public int compareTo(Base that) {\n        return Integer.compare(this.foo, that.foo); // sort by foo ascending\n    }\n}\n\nclass B extends Base implements Comparable<Base> {\n    B(int foo) {\n        super(foo);\n    }\n    public int compareTo(Base that) {\n        return -Integer.compare(this.foo, that.foo); // sort by foo descending\n    }\n}\n
\n\n

We have two classes extending Base using comparisons that don\'t follow a common rule (if there were a common rule, it would almost certainly be implemented in Base). Yet the following broken sort will compile:

\n\n
Collections.sort(Arrays.asList(new A(0), new B(1)));\n
\n\n

Wouldn\'t it be safer to only accept T extends Comparable<T>? Or is there some use case that would validate the wildcard?

My teacher requested that I create a duplicate of a Stack that returns a new Stack containing the same elements and in the same order as the specified Stack.

\n\n

If I am only able to use methods that are unique to Stack, I would pop every element off the Stack and onto a que. Then I would pop from the bottom of the que onto a new Stack and return the new Stack.

\n\n

However, I figured that since Stack inherits from Vector I could just use the addAll() method from Vector!

\n\n

Here is the Java code implementation:

\n\n
public class DuplicateStack {\n\nprivate Stack backStack;\n\npublic Stack duplicateStack(Stack s) {\n    backStack.addAll(s);\n    return backStack;\n}\n
\n\n

This would seem to do all the work for me. Only problem is, I keep getting a nullPointerException when I run this in my main:

\n\n
Stack s1 = new Stack();\ns1.push(\"c\");\ns1.push(\"b\");\ns1.push(\"a\");\n\nDuplicateStack dup = new DuplicateStack();\nStack s2 = dup.duplicateStack(s1);\n\nwhile(!s2.empty())\n    System.out.println(s2.pop());\n
\n\n

The error comes from the addAll() call in my DuplicateStack class.\nSo my question is why am I getting a nullPointerException from the addAll(), and is there any way to make a duplicate copy other than using the method stated earlier (using only Stack unique methods)?

How do I package a Universal Windows Platform library written in C# that offers only architecture-dependent builds? For the sake of illustration, let\'s say that I have some architecture-specific code conditionally compiled in for each architecture (using #if ARM and equivalents).

\n\n

To be clear, no AnyCPU build exists for my library - only x86, x64 and ARM.

\n\n

An equivalent and potentially more common situation is one where I have a dependency on an external library that is only provided as architecture-specific builds (e.g. Win2D). To keep the context simple, let\'s assume there are no dependencies and only my own code is involved - the solution should reduce to the same thing either way.

In \"PHP World\" there is a weird feeling about infrastructure layer in any DDD application (example) what I could found.

\n\n

I see many examples, when developers using Doctrine2 in infrastructure layer, use Domain entities (from Domain layer) as Doctrine2 models, puting doc comments on top on it, or mention them in config (xml, yml).\nFor instance, Big Blue Book example, this is where domain entities are located: https://github.com/codeliner/php-ddd-cargo-sample/tree/master/CargoBackend/src/Model, and as you can see it\'s highly coupled with Doctrine (look on annotations). Are they ?

\n\n

I\'ve feeling that this is wrong way.

\n\n

What I understood about DDD, is:\nRepository should make a query to persistence layer and pass result to factory to instantiate Aggregate Root entity (Domain model) properly. It means that only Factory knows how specific Aggregate Root might be instantiated, moreover there is a, so called, entities lyfe cycle. It means that not every time Domain entity should be instantiated (hydrated) via __construct.

\n\n

If I have correct feeling, then where is a good example, of proper usage Doctrine2 in DDD-like application?

The current practice for CSS with React components seems to be using webpack\'s style-loader to load it into the page in.

\n\n
import React, { Component } from \'react\';\nimport style from \'./style.css\';\n\nclass MyComponent extends Component {\n    render(){\n        return (\n            <div className={style.demo}>Hello world!</div>\n        );\n    }\n}\n

By doing this the style-loader will inject a <style> element into the DOM. However, the <style> will not be in the virtual DOM and so if doing server side rendering, the <style> will be omitted. This cause the page to have FOUC.

I have a rails application in which I use foreman to start my rails and sidekiq servers. Since foreman doesn\'t interact well with regular byebug (you can\'t see the prompt as you type), I have set up remote debugging for both my rails and sidekiq servers. This works perfectly for the rails server, but when I connect to the byebug server for the sidekiq server, I get the following:

$ bundle exec byebug -R localhost:58501\nConnecting to byebug server localhost:58501...\nConnected.\n(byebug:ctrl)\n
\n\n

And I\'m unable to catch any byebug breakpoints.

\n\n

According to the documentation, the (byebug:ctrl) prompt means that the program has terminated normally (https://github.com/deivid-rodriguez/byebug/blob/master/GUIDE.md), but sidekiq is running jobs just fine.

\n\n

Is there something incorrect in my configuration, or is sidekiq just not compatible with byebug\'s remote debugging?

\n\n

Procfile:

\n\n
sidekiq: bundle exec sidekiq\nrails: rails server\n
\n\n

config/initializers/byebug.rb:

\n\n
if Rails.env.development?\n  require \'byebug\'\n\n  def find_available_port\n    server = TCPServer.new(nil, 0)\n    server.addr[1]\n  ensure\n    server.close if server\n  end\n\n  port = find_available_port\n\n  puts \"Starting remote debugger...\"\n  Byebug.start_server \'localhost\', port\n  puts \"Remote debugger on port #{port}\"\nend\n
\n\n

Note that when I don\'t use remote debugging, byebug functions fine with sidekiq (although in foreman I can\'t see the prompt as I type).

Also note that I\'ve tried using Byebug.wait_connection = true before Byebug.start_server, but I have the same issue.

The construction of brace in (4) clearly and unambiguously calls (2). On clang, the construction of paren in (3) unambiguously calls (1) where as on gcc 5.2, it fails to compile with:

\n\n
main.cpp: In function \'int main()\':\nmain.cpp:11:19: error: call of overloaded \'B(<brace-enclosed initializer list>)\' is ambiguous\n     B paren({1, 2});\n                   ^\nmain.cpp:6:5: note: candidate: B::B(A)\n     B(A ) { }  \n     ^\nmain.cpp:5:8: note: candidate: constexpr B::B(const B&)\n struct B {\n        ^\nmain.cpp:5:8: note: candidate: constexpr B::B(B&&)\n

There I was, writing a function that takes a value as input, calls a function on that input, and if the result of that is Just x, it should return x; otherwise, it should return the original input.

\n\n

In other words, this function (that I didn\'t know what to call):

\n\n
foo :: (a -> Maybe a) -> a -> a\nfoo f x = fromMaybe x (f x)\n
\n\n

Since it seems like a general-purpose function, I wondered if it wasn\'t already defined, so I asked on Twitter, and Chris Allen replied that it\'s ap fromMaybe.

\n\n

That sounded promising, so I fired up GHCI and started experimenting:

\n\n
Prelude Control.Monad Data.Maybe> :type ap\nap :: Monad m => m (a -> b) -> m a -> m b\nPrelude Control.Monad Data.Maybe> :type fromMaybe\nfromMaybe :: a -> Maybe a -> a\nPrelude Control.Monad Data.Maybe> :type ap fromMaybe\nap fromMaybe :: (b -> Maybe b) -> b -> b\n
\n\n

The type of ap fromMaybe certainly looks correct, and a couple of experiments seem to indicate that it has the desired behaviour as well.

\n\n

But how does it work?

\n\n

The fromMaybe function seems clear to me, and in isolation, I think I understand what ap does - at least in the context of Maybe. When m is Maybe, it has the type Maybe (a -> b) -> Maybe a -> Maybe b.

\n\n

What I don\'t understand is how ap fromMaybe even compiles. To me, this expression looks like partial application, but I may be getting that wrong. If this is the case, however, I don\'t understand how the types match up.

\n\n

The first argument to ap is m (a -> b), but fromMaybe has the type a -> Maybe a -> a. How does that match? Which Monad instance does the compiler infer that m is? How does fromMaybe, which takes two (curried) arguments, turn into a function that takes a single argument?

\n\n

Can someone help me connect the dots?

I\'m new to webpack and I\'m trying to understand loaders as well as its properties such as test, loader, include etc.

\n\n

Here is a sample snippet of webpack.config.js that I found in google.

\n\n
module: {\n    loaders: [\n      {\n        test: /\\.js$/,\n        loader: \'babel-loader\',\n        include: [\n          path.resolve(__dirname, \'index.js\'),\n          path.resolve(__dirname, \'config.js\'),\n          path.resolve(__dirname, \'lib\'),\n          path.resolve(__dirname, \'app\'),\n          path.resolve(__dirname, \'src\')\n        ],\n        exclude: [\n          path.resolve(__dirname, \'test\', \'test.build.js\')\n        ],\n        cacheDirectory: true,\n        query: {\n          presets: [\'es2015\']\n        }\n      },\n    ]\n}\n
\n\n
    \n

  1. Am I right that test: /.js$/ will be used only for files with extension .js?

    2. \n

  2. The loader: \'babel-loader\', is the loader we install using npm

    3. \n

  3. The include: I have many questions on this. Am I right that anything we put inside the array will be transpiled? That means, index.js, config.js, and all *.js files in lib, app and src will be transpiled.

    4. \n

  4. More questions on the include: When files get transpiled, do the *.js files get concatenated into one big file?

    5. \n

  5. I think exclude is self explanatory. It will not get transpiled.

  6. What does query: { presets: [\'es2015\'] } do?

How would one implement something that works like the defer statement from go in python?

\n\n

Defer pushes a function call to a stack. When the function containing the defer statement returns, the defered function calls are popped and executed one by one, in the scope that the defer statement was inside in the first place. Defer statements look like function calls, but are not executed until they are popped.

Go example of how it works:

func main() {\n    fmt.Println(\"counting\")\n\n    var a *int\n    for i := 0; i < 10; i++ {\n        a = &i\n        defer fmt.Println(*a, i)\n    }\n\n    x := 42\n    a = &x\n\n    fmt.Println(\"done\")\n}\n

Is it bad or good parctice to inject namespace std::experimental into std like following?

\n\n
namespace std\n{\nnamespace experimental\n{\n}\nusing namespace experimental;    \n}\n\n#include <experimental/optional>\n\nint main()\n{\n    std::optional< int > o;\n    return 0;\n}\n
\n\n

Or even in more modern form:

\n\n
#if __has_include(<optional>)\n# include <optional>\n#elif __has_include(<experimental/optional>)\n# include <experimental/optional>\nnamespace std\n{\nusing namespace experimental;    \n}\n#else\n#error !\n#endif\n\nint main()\n{\n    std::optional< int > o;\n    return 0;\n}\n
\n\n

The intention to introduce std::experimental \"sub-namespace\" is clear because std::experimental currently contains a plenty of new libraries. I think it is very likely all them will migrate into namespace std without any substantial changes and user code written currently can rely upon this (am I totally wrong?). Otherwise all this code should be refactored to change from std::experimental:: to std:: in the future. It is not big deal, but there may be reasons not to do so.

\n\n

The question is about both production code and not-too-serious code.

I am trying to perform unit tests in Django. I have the following form in index.html:

\n\n
<form method=POST>\n  {\% csrf_token \%}\n  <input name=itemT>\n</form>\n
\n\n

And I am testing if the view render the template correctly:

\n\n

views.py

\n\n
def homePage(request):\n    return render(request, \'index.html\')\n
\n\n

tests.py:

\n\n
request = HttpRequest()\n\nresponse = homePage(request)\nif response:\n    response = response.content.decode(\'UTF-8\')\n\nexpectedHTML = render_to_string(\'index.html\')\nself.assertEqual(response, expectedHTML)\n
\n\n

The response has a hidden input field with a csrf token; however, the expectedHTML does not (there is just a blank line at the place of {\% csrf_token \%}). So the assertion always fails.

\n\n

Is it possible to have render_to_string() generate a csrf input field? If so, would the token of response the same as that of expectedHTML?

\n\n

Or, is there any way to ignore the input field such that the test can be successful?

I\'m trying to get my ASP.NET application to automatically start whenever the application pool is running.

As per the lots and lots of references online I have already done the following:

\n\n
    \n
  • Set the Application Pool to StartMode=AlwaysRunning
    • \n
  • Set the site in question (that belongs to beforementioned Pool) to preloadEnabled=true
    • \n

    • \n
  • Add the <applicationInitialization> node to the web.config\'s <system.webServer> node
    • \n

The web application is based on Owin and has a simple log4net logging statement in it\'s Startup.Configuration() method. Now when restarting IIS I see that the w3svc.exe process is running, so I know the StartMode=AlwaysRunning is working. There are however no logging messages in the log file.

\n\n

Navigating to any url (even a nonexisting one) in the application will start the app and add the log line.

Because of the actual work that\'s done in the startup of the application I really want the application to truly preload, but I seem to be unable to get it done.

Searching this site I have unfortunately not been able to find a solution.

How should I go about passing thing into the child component such that the two components can be data bound against the same thing.

\n\n

I tried to do this:

\n\n
@Component({\n  selector: \'my-app\',\n  template: \'Parent (<div #child></div>)\'\n})\nclass MyApp {\n  thing : any;\n  constructor(dcl: DynamicComponentLoader, elementRef: ElementRef) {\n    dcl.loadIntoLocation(ChildComponent, elementRef, \'child\').then(ref => {\n        ref.instance.thing = this.thing;\n    });\n  }\n}\n
\n\n

It sort of works, but they are not synchronised as you would expect.

\n\n

Basically I am trying to achieve the same thing that would have been achieved by using ng-include in angular 1 where the child is a dynamically determined component and shares the model with its parent.

Then calling functions specifying values for the inherited values gives a compilation error:

\n\n
f(Something{\n    a: \"letter a\",\n    c: \"letter c\",\n})\n
\n\n

The error message is: unknown Something field \'a\' in struct literal.

\n\n

This seems highly weird to me. Is this really the intended functionality?

\n\n

Thanks for the help!

The columns I\'m querying are all of type VARCHAR2(128) in Oracle.

\n\n

I\'m also using this exact same code in another project and it works. The only difference is that for the project that works I\'m using Oracle.DataAccess and for the one that doesn\'t work, I\'m using Oracle.ManagedDataAccess (I am unable to use Oracle.DataAccess for this project). So I believe there is a bug/problem in the managed driver.

\n\n

I\'m open to solutions or workarounds.

Hi I have a website which the page logic should only accept submit under two conditions:

1) if the captcha is actively checked

\n\n

and

\n\n

2) if at least one file is attached (only pdf and image file types are allowed up to three total) are attached.

\n\n

the issue is that we are receiving blank applications however, I am seeing a scenario where you can attach non pdfs/images with a pdf/image and still submit which strips all attachments.

\n\n

proper behavior should be:\nprevent submit if non pdf/image type attached show error message \"Only image or pdf can be uploaded\" and then a message stating this and preventing form submit at the bottom of the page in red just like the other errors.

\n\n

Be polite. Thanks. :-)

I have read some related articles but didn\'t find a perfectly fitting answer to my questions.

\n\n

I need to create a simple application to perform basic accountancy related operations. The requirement is such that multiple users (in my case up to 5 people) in the same LAN need to be able to work on the same database from their machines. As the application is going to be simple (basic add/subtract operations and storing the results in the database) I wonder whether I need to use ASP.NET or I can use WPF implementing basic communication interface (WCF seems to be a good helper) as I was working mostly with WPF and have only little experience with ASP.NET. To keep simple again, I decided to use SQLite instead of RDMS (like MS SQL Server or MySQL). I read here that it is better to use client/server DB for my purpose but I believe that the scale of my project is so small that eventual latencies will not bother me. What I need to know is whether it is wise to use WPF with SQLite database as a shared network resource and accessed by other users or it is better to dive into ASP.NET for this reason.

\n\n

To sum up my requirements:

\n\n
    \n
  1. The application is very simple in terms of performed tasks (only basic accountancy related operations),
    2. \n
  2. Simple database (SQLite is my choise),
    3. \n
  3. Multiple access but only for few people (up to 3 or 5 people),
    4. \n
  4. The users will be in the same network,
    5. \n
  5. I do not bother about eventual latencies
    6. \n
\n\n

My doubts are:

\n\n
    \n

  1. In my case - will it be wise to use SQLite concurrency embedded mechanism if the traffic is very small (only few people)? In the SQLite docs it is stated that basic concurrency is handled in terms of multiple reading access and only single write access at the same time. However I have never used concurrency in SQL so I would need an opinion of somebody more experienced in this topic,

    2. \n

  2. Is it better to learn more ASP.NET to create a basic client/server app (I would prefer SQLite as DB again) than implementing WPF with some network related stuff like accessing the shared SQLite file or using WCF to achieve the same? I mean, isn\'t it complicating everything too much by prefering WPF over ASP.NET? If the application was supposed to be big, scalable etc. I would definitely stick to ASP.NET but in the case of simplicity of the project and simplicity of creating WPF application using C# and XAML I doubt which technology to use in my particular situation to keep simple in the terms of development.

    3. \n
\n\n

If there is a better solution than the stated above, please mention it (I would prefer to stick with C# but I am open to other suggestions).

I\'m trying to understand the best practice for controlling a StatefulWidget\'s state outside of that Widgets State.

\n\n

I have the following interface defined.

\n\n
abstract class StartupView {\n  Stream<String> get onAppSelected;\n\n  set showActivity(bool activity);\n  set message(String message);\n}\n
\n\n

I would like to create a StatefulWidget StartupPage that implements this interface. I expect the Widget to do the following:

\n\n
    \n

  1. When a button is pressed it would send an event over the onAppSelected stream. A controller would listen to this even and perform some action ( db call, service request etc ).

    2. \n

  2. The controller can call showActivity or set message to have the view show progress with a message.

    3. \n
\n\n

Because a Stateful Widget does not expose it\'s State as a property, I don\'t know the best approach for accessing and modifying the State\'s attributes.

\n\n

The way I would expect to use this would be something like:

\n\n
Widget createStartupPage() {\n    var page = new StartupPage();\n    page.onAppSelected.listen((app) {\n      page.showActivity = true;\n      //Do some work\n      page.showActivity = false;\n    });\n  }\n
\n\n

I\'ve thought about instantiating the Widget by passing in the state I want it to return in createState() but that feels wrong.

\n\n

Some background on why we have this approach: We currently have a Dart web application. For view-controller separation, testability and forward thinking towards Flutter we decided that we would create an interface for every view in our application. This would allow a WebComponent or a Flutter Widget to implement this interface and leave all of the controller logic the same.

I am trying to use Choices.js within a Vue component. The component compiles successfully, but then an error is triggered:

\n\n
\n

[vue-router] Failed to resolve async component default:\n ReferenceError: document is not defined

\n
\n\n

In the browser I see:

\n\n
\n

ReferenceError document is not defined

\n
\n\n

I think this has something to do with the SSR in Nuxt.js? I only need Choices.js to run on the client, because it\'s a client only aspect I guess.

\n\n

nuxt.config.js

\n\n
build: {\n  vendor: [\'choices.js\']\n}\n
\n\n

AppCountrySelect.vue

\n\n
<script>\nimport Choices from \'choices.js\'\n\nexport default {\n  name: \'CountrySelect\',\n  created () {\n    console.log(this.$refs, Choices)\n    const choices = new Choices(this.$refs.select)\n    console.log(choices)\n  }\n}\n</script>\n
\n\n

In classic Vue, this would work fine, so I\'m very much still getting to grips with how I can get Nuxt.js to work this way.

\n\n

Any ideas at all where I\'m going wrong?

\n\n

Thanks.

Problem

\n\n

I try to upload an image with angular\'s HttpClient to API Content-Type: multipart/form-data (angular v4+). Is it supported? How to do it?

\n\n

The upload works with XMLHttpRequest when using module like ng2-fancy-image-uploader. I would prefer to use a custom method with HttpClient which i could put into a http service together with other methods for accessing API.

\n\n

Here is what i have tried so far:

\n\n

model.service.ts

\n\n
import { Injectable } from \'@angular/core\';\nimport { HttpClient, HttpHeaders, HttpResponse } from \'@angular/common/http\';\nimport \'rxjs/add/operator/toPromise\';\n\n@Injectable()\nexport class ModelService {\n  constructor(private http: HttpClient) { }\n\n  public async updateAvatar(file: File): Promise<void> {\n\n    // headers\n    const headers = new HttpHeaders()\n      .append(\'Content-Type\', \'multipart/form-data\');\n\n    const formData: FormData = new FormData();\n    formData.append(\'avatar\', file, file.name);\n\n    const response: HttpResponse = await this.http\n      .patch(\'https://example.com/avatar\', formData, { headers, observe: \'response\' })\n      .toPromise();\n\n    console.log(response.status);\n  }\n}\n
\n\n

avatar-uploader.component.ts

\n\n
import { Component, ElementRef, OnInit, ViewChild } from \'@angular/core\';\nimport { ModelService } from \'./path/to/model.service\';\n\n@Component({\n  selector: \'app-avatar-uploader\',\n  template: \'<input type=\"file\" #fileInput (changes)=\"uploadAvatar()\">\'\n})\nexport class AvatarUploaderComponent implements OnInit {\n\n  @ViewChild(\'fileInput\') fileInputElement: ElementRef;\n\n  constructor() { }\n\n  ngOnInit() { }\n\n  public async uploadAvatar() {\n    const file: File = this.fileInputElement.nativeElement.files[0];\n\n    await this.model.updateAvatar(file);\n  }\n\n}\n
\n\n

This version sends a request to (express) API, but multer (a library for parsing multipart/form-data requests) fails to parse the request.

\n\n

So i guess i either use the HttpClient incorrectly, or it doesn\'t support multipart/form-data requests.

\n\n

I guess one could send base64 encoded file or use XmlHttpRequest, but i ask specifically about HttpClient\'s ability to do it.

I want to add \"display: flex\" to flexslider2 slides but the plugin\'s javascript sets the slides to \"display: block\" so I can\'t just declare that in my wp theme stylesheet because the javascript\'s style declarations take precedence over the stylesheet\'s.

So, what\'s the best way to override javascript css? Should I even be using the flexslider plugin? Is there a better way to use jquery/js to create a slider that I can use flex properties on?

\n\n
ƒ foo() {\n  console.log(process);\n  console.log(\"development\");\n}\n

It seems like the variable \"development\" was injected while webpack was compiling the input file. At the same time webpack also injected the process object into the JavaScript code, and the browser did print out the process object when foo was called:

\n\n
{title: \"browser\", browser: true, env: {…}, argv: Array(0), nextTick: ƒ, …}\n

In fact, if I do:

window.process = process\n

I can use process.nextTick right inside the browser console! I thought the nextTick function was a Node-specific implementation! Could anybody explain this?

I am resolving an exam from last year, and one of the questions is to make a little java program where we pretty much simulate a lottery game of 6 numbers. My question is about efficiency, the exam is written on paper and I feel like if I was to write everything I typed on the computer I would not have enough time, we have 90 minutes and this is only one of the problems, swing is not my strong point so that leads me to think that I could write this in much fewer lines. The public instance variable \'key\' is there to simulate a method from another class that generates a random key that we do not need to implement. We are only allowed to use FlowLayout, BorderLayout, CardLayout and GridLayout.

\"Even

\n\n

And many thousands more...

\n\n

Currently in MongoDB Compass I am using the following query:

\n\n
{ \"Category\" : \"BOND\" }\n
\n\n

But of course this just returns 1 document that where the Category is BOND.

\n\n

Can anybody tell me how I can query to find all documents where the field name \"Category\" contains the word \"BOND\" within it?

\n\n

Many thanks,\nG

I want my code to empty a specific text file, when it is the beginning of each month. I have this code but it doesn\'t seem to work, do I have something wrong with the syntax maybe?

\n\n
public void monthlyCleanse(File f){\n\n    LocalDate localDate = LocalDate.now();\n\n    String d = DateTimeFormatter.ofPattern(\"dd\").format(localDate);\n\n    System.out.println(d);\n\n    if(d.equals(\"01\")){\n\n\n        \"filename.txt\".replace(toString().valueOf(f), \"\");\n    }\n}\n
\n\n

As you can see I am changing the format to only show the day of the month, then I am checking if that day equals \"01\" then do something...which is to empty a text file.

\n\n

Then i am calling it here...

\n\n
    monthlyCleanse(new File(\"filename.txt\"));\n
\n\n

How can i make sure that this file is emptied?

I recently updated Google Chrome to the 61.0.3163.79 version and it was suddenly very slow with canvas. This issue only appears on Linux.

For exemple, http://vincentgarreau.com/particles.js/ was 60 FPS before the Chrome update, and now it run at 2 FPS.

What\'s wrong with the new Google Chrome update ?
