• Programmatic Content Marketing in the B2B Segment

    Learn how content marketing platforms are used and can improve campaigns of agencies, media buyers.


    What’s Wrong with the Traditional Display Advertising?


    Various advertising formats demonstrate not equal efficiency in the B2C and B2B markets since decisions of private and corporate customers are influenced by different factors. While B2C sales are often driven by emotional aspect, prospects in B2B segment need relevant expert information to initiate a purchase. Since transaction price is high, they make decisions thoughtfully and need more time and data to make a deal. Marketing managers should consider these features when managing advertising campaigns for B2B advertisers.


    Unfortunately, the lion’s share of advertisers still promotes their goods and services through traditional online-display advertising id est banners. Low efficiency of such advertising strategy is caused by two major problems:


    1 — the wrong content
    2 — is shown to the wrong audience


    Let’s talk about both issues in details.

  • Checking the GCC 10 Compiler with PVS-Studio

      PVS-Studo vs GCC 10

      The GCC compiler is written with copious use of macros. Another check of the GCC code using PVS-Studio once again confirms the opinion of our team that macros are evil in the flesh. Not only does the static analyzer struggle with reviewing such code, but also a developer. GCC developers are certainly used to the project and are well versed in it. Nonetheless, it is very difficult to understand something on the third hand. Actually, due to macros, it was not possible to fully perform code checking. However, the PVS-Studio analyzer, as always, showed that it can find errors even in compilers.

    • WAL in PostgreSQL: 4. Setup and Tuning

      • Translation
      So, we got acquainted with the structure of the buffer cache and in this context concluded that if all the RAM contents got lost due to failure, the write-ahead log (WAL) was required to recover. The size of the necessary WAL files and the recovery time are limited thanks to the checkpoint performed from time to time.

      In the previous articles we already reviewed quite a few important settings that anyway relate to WAL. In this article (being the last in this series) we will discuss problems of WAL setup that are unaddressed yet: WAL levels and their purpose, as well as the reliability and performance of write-ahead logging.

      WAL levels


      The main WAL task is to ensure recovery after a failure. But once we have to maintain the log anyway, we can also adapt it to other tasks by adding some more information to it. There are several logging levels. The wal_level parameter specifies the level, and each next level includes everything that gets into WAL of the preceding level plus something new.

        Hello, Habr!


        About a month ago, I had a feeling of constant anxiety. I began to eat poorly, sleep even worse, and constantly read to a ton of news about the pandemic. Based on them, the coronavirus either captured, or liberated our planet, was either a conspiracy of world governments, or the vengeance of the pangolin, the virus either threatened everyone at once, or personally me and my sleeping cat…


        Hundreds of articles, social media posts, youtube-telegram-instagram-tik-tok (yes, I sin) content of varying degrees of content quality did not lead me to anything but an even greater sense of anxiety.


        But one day I bought buckwheat decided to end it all. As soon as possible!

        • What is Reactive Programming? iOS Edition

            There are many articles about Reactive Programming and different implementations on the internet. However, most of them are about practical usage, and only a few concern what Reactive Programming is, and how it actually works. In my opinion, it is more important to understand how frameworks work deep inside — spoiler: nothing actually complicated there — rather than starting to use a number of traits and operators meanwhile shooting yourself in the foot.


            So, what is RxSwift Combine Reactive programming?

          • Does gender segregation in the labor market still persist?

              Common sense prompts that gender segregation and gender discrimination on labor market have declined. There is a popular opinion that too much is talked about smaller women’s chances to blossom forth at work, while the problem was solved long ago. Actually, women all over the world have the same opportunities as men to get higher education, to hold a supervisor or manager position, to climb the career and salary ladder.



              The biggest corporations and companies run special programs to shorten gender inequality on labor market. That seems like the evidence: smaller firms try to imitate the policy, and also values, of world famous companies in order to succeed and gain benefit like the second ones do (it is an economic-sociological proved behavior), so in nearest future, or perhaps in present, all players on labor market will popularize the idea of gender equality in all its senses. However, the state of affairs is far from desired. Even if organizations follow gender unbiased strategy, will it solve the global problem of gender inequality at work overall?

              This is the guest article by Maria Antomony, HSE University graduate student, sociologist and code passionate.

                • «Build it & Break it»: How some algorithms generate captcha, while others crack it

                  Hello, Habr! Let's me present you a translation of an article "«Ломай меня полностью!» Как одни алгоритмы генерируют капчу, а другие её взламывают", author miroslavmirm.

                  Doesn't matter what kind of intelligence you have — be it artificial or natural — after this detailed analysis no captcha will be an obstacle. At the end of the article, you can find the simplest and most effective workaround solution.

                  CAPTCHA is a completely automated public Turing test to tell computers and humans apart by automatically setting up specific tasks that are difficult for computers but simple for human. This technology has become the security standard used to prevent automatic voting, registration, spam, brute-force attacks on websites, etc.

                • About Testing

                    Let's talk about Testing, about unit and integration tests which everyone here, i hope, likes to write.

                    Despite of lots of benefits, tests have two fundamental problems: there is no architecture at all (quality), nobody knows what is the meaning of the quantity.

                    Tests have a cost. Lets imagine dialog between manager and developer:
                    — John, how many hours does it take to implement?
                    — Approximately one week: 1,5 day for task and 3,5 days to write tests

                    So why people write tests? Let's try to build a mental model: we delivered a component, our beta testers found a bug, we wrote tests scenario. So, next time we try to deliver the same component, we already know about bad scenario and have automation to check it. So far so good. Next, we are trying to predict future bugs by writing lot's of tests and cover bad scenarios. Next, we deliver better components, users are happy. Profit. (Despite of all pros, the solution is not scalable — with every new component we will face a reality).

                      As of 2020, video marketing is, perhaps, the most popular and reliable way to advance via content marketing. Yes, useful articles, link exchanges, and advertising posts are still useful. However, video content is a much better way to sell your product to users. You can verify this by looking at the statistics, which suggests that in 2021 users will spend an average of 100 minutes a day watching a video. And if this is not enough for you, then polls suggest that about 48% of consumers prefer to learn about new products through video content.

                      • Amid COVID-19 Pandemic, 3D Printing Helps with Medical Equipment Shortage

                          image

                          With medical equipment drastically growing scarce, a number of organizations and enterprises have taken up the development and manufacture of mechanical ventilators, relying on fast production by means of 3D printing technologies. 3D printing is often implemented in the medical field, but now, it's proving to be of great help during the emergency.

                          The first news of 3D printed ventilation apparatus came from Spain (apart from the case of 3D printing of valves at an Italian hospital). Here, we are talking about the so-called Ambu bags — temporary manual ventilators usually applied in the field by, paramedics. A whole consortium was involved in the development of the 3D printed version with the mechanical drive mechanism. The Leitat Technology Center in Barcelona played the leading role; support was provided by the Catalan Health Service, Barcelona's Zona Franca industrial estate, Hewlett Packard Enterprise, and the Parc Taulí Hospital in Sabadell, which houses the Faculty of Medicine of the Autonomous University of Barcelona.

                                Static analysis is an extremely useful tool for any developer, as it helps to find in time not only errors, but also suspicious and strange code fragments that may cause bewilderment of programmers who will have to work with it in the future. This idea will be demonstrated by the analysis of the TensorFlow.NET open C# project, developed for working with the popular TensorFlow machine learning library.
