    Ray Cast Visual Search (RCVS). Fast and simple algorithm for searching 3D objects with similar shapes

      For me, these two models are quite similar, but in fact they don’t have obvious characteristics to measure this similarity. These models have different numbers of vertices, edges and polygons. They are of different sizes, rotated differently and both have the same transforms (Location = [0,0,0], Rotation in radians = [0,0,0], Scale = [1,1,1]). So how to determine their similarity?

      10 SEO Myths to Leave Behind in 2020

      • Search engines,
      • Search engine optimization
        To say SEO has “changed a lot” would be the understatement of the decade. We’ll often see multiple updates per year from Google, like the BERT update in October aimed at helping the search engine better interpret natural language searches. Or the site diversity update in June, which focused on reducing duplicate organic listings on SERPs for the same site.

        SEO vs. PPC — What's better for your business?

        • Search engines,
        • Internet marketing,
        • Display advertising,
        • Contextual advertising,
        • Search engine optimization
          What's better for your business?

          At a certain point, any website owner wonders what's better: SEO or PPC? Which promotion strategy will be the most rational to use in this particular situation? Or maybe it's best to combine both?

          Before you decide between SEO and PPC, you need to consider the differences between them…

          • Search engines,
          • Internet marketing,
          • Search engine optimization
            Let's say, your website offers content, products, or services for people from different regions or countries who speak different languages. Search engines will probably count this as duplicate content, leading to low rankings.

            PVS-Studio for Java hits the road. Next stop is Elasticsearch

            • PVS-Studio corporate blog,
            • Search engines,
            • Open source,
            • Java

              Picture 1

              The PVS-Studio team has been keeping the blog about the checks of open-source projects by the same-name static code analyzer for many years. To date, more than 300 projects have been checked, the base of errors contains more than 12000 cases. Initially the analyzer was implemented for checking C and C++ code, support of C# was added later. Therefore, from all checked projects the majority (> 80%) accounts for C and C++. Quite recently Java was added to the list of supported languages, which means that there is now a whole new open world for PVS-Studio, so it's time to complement the base with errors from Java projects.

              The Java world is vast and varied, so one doesn't even know where to look first when choosing a project to test the new analyzer. Ultimately, the choice fell on the full-text search and analytical engine Elasticsearch. It is quite a successful project, and it's even especially pleasant to find errors in significant projects. So, what defects did PVS-Studio for Java manage to detect? Further talk will be right about the results of the check.

              How to Discover MongoDB and Elasticsearch Open Databases

              • Information Security,
              • Search engines,
              • System administration,
              • Database Administration

                Some time ago among security researchers, it was very “fashionable” to find improperly configured AWS cloud storages with various kinds of confidential information. At that time, I even published a small note about how Amazon S3 open cloud storage is discovered.


                However, time passes and the focus in research has shifted to the search for unsecured and exposed public domain databases. More than half of the known cases of large data leaks over the past year are leaks from open databases.



                Today we will try to figure out how such databases are discovered by security researchers...
