    Any interesting new techniques anyone follows? Even old are current ones are welcome :) Just want to see how more experienced programmers approach problems.

    Also, any good books on this topic that are a must to read?

    Edit: the type of problem here is open to interpretation. I think there is a similar pattern that can be applied to problems of any type.

    Any clue about how to implement DRM in pdf, ppt or documents?

    Posted: 19 May 2020 04:13 AM PDT

    I am finding methods for content protection in the form of digital rights management for documents. I have been through the various types of technologies they use for streaming services I need to apply these to an Android application. I'd be thankful if any of you could help me out or even share a resource for this ( I have been through the Android documentation already)

    What to learn to become a self-taught programmer?

    Posted: 18 May 2020 09:44 PM PDT

    Hello there beginner computer science student here. I was just wondering what kind of introductory course is great to learn before continuing to learn any kind of programming language. Something perhaps that helps with computational or abstract thinking or anything that could help enhance problem solving skills.

    Artificial intelligence: How long would it take for someone to creat an ai from scratch?

    Posted: 18 May 2020 08:36 PM PDT

    I ran into someone who claims they made an ai software. They posted a video of it. The best I can say is it kind of looked like Jarvis from iron man. They showed it on their tv. But I thought how easily you could fool someone by just making an animation of an ai on after effects and just showing it on your tv. I had my doubts because this is someone that post everything about their life on social from dates to food they eat. But nothing suggests on their social media that they are or ever were a programmer or anything. Idk maybe I'm just skeptical or jealous. But they claim to have made an ai comparable to siri in 8 months, By themselves. Idk seems fishy too me...

    [R] Bringing Old Photos Back to Life

    Posted: 18 May 2020 08:52 AM PDT

    We invited Bo Zhang, the co-author of the paper Bringing Old Photos Back to Life, to share this research.

    " We propose to restore old photos that suffer from severe degradation through a deep learning approach. Unlike conventional restoration tasks that can be solved through supervised learning, the degradation in real photos is complex and the domain gap between synthetic images and real old photos makes the network fail to generalize. Therefore, we propose a novel triplet domain translation network by leveraging real photos along with massive synthetic image pairs. Besides, to address multiple degradations mixed in one old photo, we design a global branch with a partial nonlocal block targeting to the structured defects, such as scratches and dust spots, and a local branch targeting to the unstructured defects, such as noises and blurriness. The proposed method outperforms state-of-the-art methods in terms of visual quality for old photos restoration."

    Here is the read: Bringing Old Photos Back to Life

    Covid simulation that started lockdown was written in Fortran

    link to article

    I am beginner lever programmer and I rate myself 3/10 in my understanding of computer science. Handful of apps and automation scripts to my name. Can anybody tell me more about the fortran simulation and how it might have gone wrong? Apart for 40yrs old language and 15000 lines of code?

    Front-end -- Popup close button not closing the popup

    Posted: 18 May 2020 12:29 PM PDT

    I've been working on this popup that displays upon the webpage loading. It shows up, but for some reason the close button does not work. I'm a little inexperienced with front end, but I've been reading up on some tutorials and it seems if you wanna make something close you use the class "close." So I tried that, but to no success.

    I made a simplified test version of my website to eliminate possible external sources of the error.

    Oddly enough, it works on codepen and other compilers, but not when I open my file. This is the codepen ( https://codepen.io/Lavender786/pen/YzyRapR )

    This is what its looking like:

    HTML:

    <html>

    <head>

    <link rel="stylesheet" type="text/css" href="style.css"/>

    <script type="text/javascript" src="script.js"></script>

    </head>

    <body>

    <div id="ac-wrapper">

    <div id="popup">

    <center>

    <h3> welcome </h3>

    <a class="close" href="#">&times;</a>

    </center>

    </div>

    </div>

    </body>

    </html>

    the javascript file script.js

    function PopUp(){

    document.getElementById('ac-wrapper').style.display="block";

    }

    document.querySelector('.close').addEventListener("click",()=> document.getElementById('ac-wrapper').style.display='none');

    And the style file

    #ac-wrapper {

    position: fixed;

    top: 0;

    left: 0;

    width: 100%;

    height: 100%;

    background: rgba(255,255,255,.6);

    z-index: 1001;

    }

    #popup{

    display: "none";

    width: 555px;

    height: 375px;

    background: #FFFFFF;

    border: 5px solid #000;

    border-radius: 25px;

    -moz-border-radius: 25px;

    -webkit-border-radius: 25px;

    box-shadow: #64686e 0px 0px 3px 3px;

    -moz-box-shadow: #64686e 0px 0px 3px 3px;

    -webkit-box-shadow: #64686e 0px 0px 3px 3px;

    position: relative;

    top: 150px; left: 375px;

    }
