I couldn't find an artifact for the Towards HTTPS Everywhere on Android paper.

@principis how did you find this data? I believe the initial data we put on the website was based on an excel sheet from Thorsten Holz. I'd like to make sure that we update to the correct data before making such changes.

@vahldiek The list of papers that is currently on secartifacts seems to be generated from the spring/summer/fall quarter accepted papers sites. But I noticed that not all papers on the technical sessions page or in the proceedings are on those sites. Since I needed the data anyway for my thesis, I scraped the technical sessions page, followed the links to the presentation page and checked if there is an "Artifact Evaluated" image.

Here is my (very basic) script:

<?php

$url = 'https://www.usenix.org/conference/usenixsecurity20/technical-sessions';

$xml = new DOMDocument();
libxml_use_internal_errors(true);

if (!$xml->loadHTMLFile($url)) {
    die("Failed to parse html from source={$url}");
}

$finder = new DomXPath($xml);
$classname = 'node-paper';
$nodes = $finder->query("//*[contains(concat(' ', normalize-space(@class), ' '), ' $classname ')]");
foreach($nodes as $node) {
    $title = trim($node->firstElementChild->nodeValue);
    $paperUrl = 'https://www.usenix.org'.$node->firstElementChild->firstElementChild->getAttribute('href');

    $content = file_get_contents($paperUrl);
    if (strstr($content, 'https://www.usenix.org/sites/default/files/usenix_artifact_evaluation_passed_125.png')) {
        echo "{$title} : {$paperUrl}".PHP_EOL;
    }
}
