I am using gulp. 

I would like to having one or multiple JS files (say jQuery) to combine them in one, minify it, and write it to a distribution folder. 

This is how I do it: 

    minifyJS([&#39;/js/myModule.file1.js&#39;,
              &#39;/js/myModule.file2.js&#39;], &#39;/dist/js&#39;, &#39;myModule&#39;)

the function: 

    function minifyJS(sourceFiles, destinationFolder, filenameRoot) {
        return gulp.src(sourceFiles)
            .pipe(plumber())
    
            // .pipe(sourcemaps.init()) here ???
            .pipe(concat(filenameRoot + &#39;.js&#39;))
            .pipe(sourcemaps.init()) // or here ???
    
            .pipe(gulp.dest(destinationFolder)) // save .js
            .pipe(uglify({ preserveComments: &#39;license&#39; }))
            .pipe(rename({ extname: &#39;.min.js&#39; }))
            .pipe(gulp.dest(destinationFolder)) // save .min.js
            .pipe(sourcemaps.write(&#39;maps&#39;))
            .pipe(gulp.dest(destinationFolder)) // save .map
    }


What I am not sure about is the `sourcemaps.init()` location...   

Should I create multiple (2 in my case) map files (that would be nice if is supported by browsers) or only one (*/maps/myModule.map*)?

I am doing this:

    toolbar = (Toolbar) findViewById(com.sports.unity.R.id.tool_bar);
    setSupportActionBar(toolbar);
    setTitle(&quot;hello&quot;);

I want to set a custom font for the text here in the title &quot;hello&quot;. How to do that?

I just started to build a ubuntu server on DigitalOcean. When I start the nginx service, it gives the following error:

    /etc/nginx/sites-enabled$ service nginx start
    Failed to start nginx.service: The name org.freedesktop.PolicyKit1 was not provided by any .service files

I have never seen this before and searching on google seemed the solutions were not quite straightforward.

I have this issue during package installation in R version 3.0.2 (2013-09-25) on an Ubuntu machine:

    install.packages(&quot;randomForest&quot;)
    Installing package into ‘/usr/local/lib/R/site-library’
    (as ‘lib’ is unspecified)

I&#39;m building a new Docker image based on the standard Ubuntu 14.04 image. 

Here&#39;s my *Dockerfile*:

    FROM ubuntu:14.04
    RUN apt-get update -y
    RUN apt-get install -y nginx git python-setuptools python-dev
    RUN easy_install pip
    ADD . /code
    WORKDIR /code
    RUN pip install -r requirements.txt # only &#39;django&#39; for now
    ENV projectname myproject
    EXPOSE 80 8000
    WORKDIR ${projectname}
    CMD [&#39;python&#39;, &#39;manage.py&#39;, &#39;runserver&#39;, &#39;0.0.0.0:80&#39;]

When I try to run this image, I get this error...

 

&gt;    /bin/sh: 1: [python,: not found

But if I open a shell when running the image, running `python` opens the interactive prompt as expected. 

Why can&#39;t I invoke `python` through `CMD` in the Dockerfile?

I am trying to setup webserver with `PHP 7 RC3` + `Nginx` on `Ubuntu 14.04` (for test purposes).

I installed Ubuntu in Vagrant using `ubuntu/trusty64` and PHP 7 RC 3 from Ondřej Sur&#253; (https://launchpad.net/~ondrej/+archive/ubuntu/php-7.0).

I can not find the way to install `MySQL PDO` (PHP sees `PDO` class but not anything related to MySQL, like `PDO::MYSQL_ATTR_DIRECT_QUERY` etc.)

Looks like there is no lib `php7.0-mysql` (by analogy with standard `php5-mysqlnd` and `php7.0-fpm` etc. from Ondřej)

Section `PDO` in `phpinfo()`:

    PDO support	     enabled
    PDO drivers	     no value

How can I get it?

So I just installed Ubuntu, and this is my first time working in a Linux environment, so bear with my noobishness here.

Anyway, I downloaded the Java 8 JDK directly from Oracle, but I understand there&#39;s also an OpenJDK for Java 8 as well. I have two questions.

1. What is the difference between the Oracle version and OpenJDK. Pros/Cons?

2. When I try and get OpenJDK 8, I can&#39;t. I&#39;m pasting the terminal command and the error message I get here, hoping for advice. Again, very new to Linux, been on my first Linux distro ever for less than an hour here at this point.

        user@computer:~/Java$ sudo apt-get install openjdk-8-jdk
        Reading package lists... Done
        Building dependency tree       
        Reading state information... Done
        E: Unable to locate package openjdk-8-jdk

Any help would be appreciated. In the meantime, I&#39;m just gonna use the Oracle package. Thanks.

Edit:

So, now I have a new problem. I installed OpenJDK 7, it came with Maven and just installed before I realized I was getting a two-for-one deal. Now I have JDK 7, and Eclipse, and Maven, and they&#39;re all working, but I&#39;m stuck on JDK 7 rather than 8.

I saw that there&#39;s a link below, I intend to check it out in the morning, it&#39;s 2am and I&#39;m tired right now. Any other advice for this new issue would be appreciated, otherwise I will definitely be checking out that link first thing in the morning.
