javascript array assign to multiple variable : i got a bit logic problem. i wan't to assign array to several variable. but it's doesn't work. appreciate for your help. function Case(values){ var x = values; var A = []; var B = []; var C = []; var temp = 0; A.push(values[i]); B.push(values[i]); C.push(values[i]); } var values = [5, 4, 3, 6, 7 , 8]; Case(values); Output expect: A = [5, 6]; B = [4, 7]; A = [3, 8];

Java Lambdas Interfaces : <p>As you all know we engineers works best at nights :) I was studying lambdas at yesterday night and I saw a piece of code like that,</p> <pre><code> BirdCompare tester = new BirdCompare(); MathOperation addition = (a, b) -&gt; (a + b); MathOperation subtraction = (int a, int b) -&gt; (a - b); MathOperation multiplication = (int a, int b) -&gt; { return a * b; }; MathOperation division = (a, b) -&gt; a / b; interface MathOperation { int operation(int a, int b); } </code></pre> <p>The sample simply assigned lambda expression to MathOperation interface's variable but how ? It makes a implementation of method named <strong>operation</strong> which is in the interface and the point I was confused is assignment of that implementation to the variable of interface.

Your project.json doesn't list 'win10' as a targeted runtime : <p>I hate reposting, but I thought posting to the <a href="https://social.msdn.microsoft.com/Forums/en-US/efb7e560-e2e4-4385-8287-a6ada4e3622b/uwphtml-problem-with-uap-app-running-with-references-to-a-pcl?forum=wpdevelop" rel="noreferrer">MSDN forum</a> was the right thing to do since it looks there are not many people working on UWP apps with HTML/JavaScript, but, since I had no answers at all, I'm turning to the great SO community for help.</p> <p><em>Problem:</em><br> I have a very simple UAP app in HTML/JavaScript that has a reference to a Windows Runtime Component which has a reference to a Class Library.</p> <p>I need to project to run in either PCs and/or mobiles so I need to compile it with Any CPU. The problem is that whenever I want to compile my app I get the following error:</p> <p><code>Your project.json doesn't list 'win10' as a targeted runtime. You should add '"win10": { }' inside your "runtimes" section in your project.json, and then re-run NuGet restore.</code></p> <p>And If I do add the plain win10 entry under runtimes, I get many other errors.

How to address 'OSError: libc not found' raised on Gunicorn exec of Flask app inside Alpine docker container : <p>I'm working on a Flask application based on the Microblog app from Miguel Grinberg's mega-tutorial. Code lives here: <a href="https://github.com/dnilasor/quickgig" rel="noreferrer">https://github.com/dnilasor/quickgig</a> . I have a working docker implementation with a linked MySQL 5.7 container. Today I added an Admin View function using the Flask-Admin module. It works beautifully served locally (OSX) on Flask server via 'flask run' but when I build and run the new docker image (based on python:3.8-alpine), it crashes on boot with a <code>OSError: libc not found</code> error, the code for which seems to indicate <a href="https://github.com/benoitc/gunicorn/blob/438371ee90b9676336a44c7abaeb30ee7fc57a5c/gunicorn/socketfromfd.py#L26" rel="noreferrer">an unknown library</a></p> <p>It looks to me like Gunicorn is unable to serve the app following my additions. My classmate and I are stumped!</p> <p>I originally got the error using the python:3.6-alpine base image and so tried with 3.7 and 3.8 to no avail. I also noticed that I was redundantly adding PyMySQL, once in requirements.txt specifying version no. and again explicitly in the dockerfile with no spec. Removed the requirements.txt entry. Also tried incrementing the Flask-Admin version no. up and down. Also tried cleaning up my database migrations as I have seen multiple migration files causing the container to fail to boot (admittedly this was when using SQLite). Now there is only a single migration file and based on the stack trace it seems like the <code>flask db upgrade</code> works just fine.</p> <p>One thing I have yet to try is a different base image (less minimal?), can try soon and update this. But the issue is so mysterious to me that I thought it time to ask if anyone else has seen it : )</p> <p>I did find <a href="https://bugs.python.org/issue28134" rel="noreferrer">this socket bug</a> which seemed potentially relevant but it was supposed to be fully fixed in python 3.8.</p> <p>Also FYI I followed some of the advice <a href="https://github.com/miguelgrinberg/microblog/issues/49" rel="noreferrer">here</a> on circular imports and imported my admin controller function inside <code>create_app</code>.</p> <p>Dockerfile:</p> <pre><code>FROM python:3.8-alpine RUN adduser -D quickgig WORKDIR /home/quickgig COPY requirements.txt requirements.txt RUN python -m venv venv RUN venv/bin/pip install -r requirements.txt RUN venv/bin/pip install gunicorn pymysql COPY app app COPY migrations migrations COPY quickgig.py config.py boot.sh ./ RUN chmod +x boot.sh ENV FLASK_APP quickgig.py RUN chown -R quickgig:quickgig ./ USER quickgig EXPOSE 5000 ENTRYPOINT ["./boot.sh"] </code></pre> <p>boot.sh:</p> <pre><code>#!/bin/sh source venv/bin/activate while true; do flask db upgrade if [[ "$?" == "0" ]]; then break fi echo Upgrade command failed, retrying in 5 secs... sleep 5 done # flask translate compile exec gunicorn -b :5000 --access-logfile - --error-logfile - quickgig:app </code></pre> <p>Implementation in <strong>init</strong>.py:</p> <pre><code>from flask_admin import Admin app_admin = Admin(name='Dashboard') def create_app(config_class=Config): app = Flask(__name__) app.config.from_object(config_class) ... app_admin.init_app(app) ... from app.admin import add_admin_views add_admin_views() ... return app from app import models </code></pre> <p>admin.py:</p> <pre><code>from flask_admin.contrib.sqla import ModelView from app.models import User, Gig, Neighborhood from app import db # Add views to app_admin def add_admin_views(): from . import app_admin app_admin.add_view(ModelView(User, db.session)) app_admin.add_view(ModelView(Neighborhood, db.session)) app_admin.add_view(ModelView(Gig, db.session)) </code></pre> <p>requirements.txt:</p> <pre><code>alembic==0.9.6 Babel==2.5.1 blinker==1.4 certifi==2017.7.27.1 chardet==3.0.4 click==6.7 dominate==2.3.1 elasticsearch==6.1.1 Flask==1.0.2 Flask-Admin==1.5.4 Flask-Babel==0.11.2 Flask-Bootstrap==3.3.7.1 Flask-Login==0.4.0 Flask-Mail==0.9.1 Flask-Migrate==2.1.1 Flask-Moment==0.5.2 Flask-SQLAlchemy==2.3.2 Flask-WTF==0.14.2 guess-language-spirit==0.5.3 idna==2.6 itsdangerous==0.24 Jinja2==2.10 Mako==1.0.7 MarkupSafe==1.0 PyJWT==1.5.3 python-dateutil==2.6.1 python-dotenv==0.7.1 python-editor==1.0.3 pytz==2017.2 requests==2.18.4 six==1.11.0 SQLAlchemy==1.1.14 urllib3==1.22 visitor==0.1.3 Werkzeug==0.14.1 WTForms==2.1 </code></pre> <p>When I run the container in interactive terminal I see the following stack trace:</p> <pre><code>(venv) ****s-MacBook-Pro:quickgig ****$ docker run -ti quickgig:v7 INFO [alembic.runtime.migration] Context impl SQLiteImpl.

PostgreSQL(Full Text Search) vs ElasticSearch : <p>Hi I am doing some research before I implement search feature into my service. I'm currently using PostgreSQL as my main storage. I could definitely use PostgreSQL's built-in Full-Text-Search but the problem is that I have data scattered around several tables. </p> <p>My service is an e-commerce website. So if a customer searches "good apple laptop", I need to join <code>Brand</code> table, <code>post</code> table and <code>review</code> table(1 post is a combination of several reviews + short summary) to fully search all posts. If I were to use elasticsearch, I could insert complete posts by preprocessing.</p> <p>From my research, some people said PostgreSQL's FTS and elasticsearch have similar performance and some people said elasticsearch is faster. Which would be better solution for my case?</p> <p>Thanks in advance</p>

Here is my current attempt but it is not working:</p> <p><strong>Startup.cs</strong></p> <pre><code>public IMapper Mapper { get; set; } private MapperConfiguration MapperConfiguration { get; set; } public void ConfigureServices(IServiceCollection services) { services.AddTransient&lt;IMapper, Mapper&gt;(); } public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { MapperConfiguration MapperConfiguration = new MapperConfiguration(cfg =&gt; { cfg.CreateMap&lt;Product, ProductViewModel&gt;().ReverseMap(); }); Mapper = MapperConfiguration.CreateMapper(); } </code></pre> <p><strong>In my controller:</strong></p> <pre><code>private IMapper _mapper { get; set; } // Constructor public ProductsController(IMapper mapper) { _mapper = mapper; } public IActionResult Create(ProductViewModel vm) { Product product = _mapper.Map&lt;ProductViewModel, Product&gt;(vm); } </code></pre> <p>It just isn't working at all... I must be missing some step or doing something wrong.</p>

debugging simple LISP functions. : <p>I am very new to lisp, and am having a hard time even getting my feet wet. I'm sure once, I have a few functions working, I'll be able to build upon them and work on higher order functions, and more complex problems. </p> <p>Can someone point out my errors in the following code. </p> <pre><code>(defun indeHelper(A L N) (cond (Null N) nil) ((= A (first L) (cons N (indeHelper A (rest L) (+ 1 N))))) (t (indeHelper A (rest L) (+ 1 N)))) (defun inde(A L) (funcall indeHelper(A L 1))) </code></pre> <p>Also how would I call this? I have one function I think is working ok, but I can't get the syntax for calling it. Thanks for any help.</p>

Recomendation: how to load dynamically a post with laravel : <p>I need a recommendation. I want to have a sidebar with all the titles of the posts and by clicking on any of them that this is loaded with its content in the main section of the page. The idea is that when loading the page not all the contents of each post are loaded, but only when clicking. What system can I use if I am using Laravel?</p> <p><a href="https://i.stack.imgur.com/xHHEn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xHHEn.png" alt="enter image description here"></a></p>

Is it possible to have same interface in javaee app and use it in CLI and GUI both? : <p>We have a javaee application whithout any gui. To adding some records to database config. tables( entities) we use manual sql script which is not safe and easy. We have decided to develop gui and also CLI for our application to handle this issue. Is it possible to have interfaces in javaee app and use then in both Gui and CLI? From end-user point of veiw, services and parameters arr same in both gui and cli. Something like jboss admin web console and jboss cli to deploy an artifact.</p>
