However, C++’s type system does not really conform to these elements. As a consequence, developers have to pay attention to avoid mistakes because of the missing compiler support. Moreover, C++11 provides an approach in which exceptions appear in the function’s signature in an inverse manner compared to the earlier standards. Static analysis is an approach in which we reason about a program based on the source with no execution of the analyzed code. It can be used for many purposes, for instance, finding bugs, refactoring the code, or measuring code complexity. In this paper, we analyze how the older style exception specifications can be rejuvenated for modern idioms. Explicitly marking the functions as having a guaranteed exception-free execution is the primary way since C++11. We develop a static analyzer tool for providing hints for these specifications. We evaluate our method with the analysis of open-source projects. Based on the previous evaluation, not using the strictest possible exception-specification is a problem that occurred in every analyzed project. We would like to assist developers in identifying instances of this problem by providing an integrated comprehension tool, that enables them to make use of the exception analysis results in an interactive way in their IDEs.","PeriodicalId":41192,"journal":{"name":"IPSI BgD Transactions on Internet Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85754306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper is motivated by possible application of the metaheuristic simulated annealing to the process of obtaining a close approximation of the Pareto front by a set of non-dominated solutions of the p-location problem. Contrary to the other approaches, the suggested method is based on minimization of non-dominated solution set area, which directly describes quality of the approximation. Elements of the simulated annealing method are used for random breaking some limits imposed on local characteristics of the improving process. The presented results of the numerical experiments give an insight to relations among the simulated annealing parameters and optimization process efficiency.","PeriodicalId":41192,"journal":{"name":"IPSI BgD Transactions on Internet Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82670987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transaction maintains consistency by shifting the database from one consistent state to another, protected by atomicity, isolation, and durability. This paper focuses on the isolation and parallelism allowing distributed access to the data tuple across multiple transactions. Access to the data tuple is marked by the locks applied on the row level. Locks can be shared expressing data retrieval process or exclusive intended to change the values of the columns. The general locking rule takes the lock before the operation and releases it just after the operation or at the end of the transaction. Oracle database, however, does not release the lock physically, whereas the data block access would be necessary to be reloaded during the transaction approval. Therefore, this paper aims in optimizing the process of unlocking data before the data retrieval process using multiple strategies.","PeriodicalId":41192,"journal":{"name":"IPSI BgD Transactions on Internet Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85151636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Natural semantics is important from the point of view of verifying the properties of the language and for expressing the dynamics of the calculation and the construction of a set of states during the calculation. Domain-specific languages are used more and more in practice, therefore their inclusion in the curriculum of the subject Semantics of Programming Languages is a significant innovation of the traditional way of teaching the semantics of (mostly) imperative languages. In the article, we present the basics of the natural semantics of the robot language and its software visualization. For this, we have developed an application, the use of which is of great importance in the teaching itself and allows students to easily understand the basics of formal semantics thanks to interactivity.","PeriodicalId":41192,"journal":{"name":"IPSI BgD Transactions on Internet Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90872743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes a language definition tool that uses a metamodel specification instead of grammar as the basis of the language definition. Inspired by a similar Java tool known as YAJCo, the metamodel is defined using usual object-oriented techniques—as classes in the Python programming language, and the result of the parsing process is a graph of objects. The tool is demonstrated in a case study of a simple imperative programming language. We explain our design decisions and also demonstrate the suitability of a dynamic language such, as Python, for this task.","PeriodicalId":41192,"journal":{"name":"IPSI BgD Transactions on Internet Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76200900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The platform very often ranks among the top 3 most popular platforms, it allows sending and sharing both text and graphic messages - pictures, gifs and video sequences. In 2021, we conducted an online research survey among nearly 3,500 respondents aged 15 - 20. We were interested in whether and to what extent the respondents have experienced sexting, what is the ratio of male to female recipients of sexting or sexual content, who is the most frequent sender of sexting content etc. We were also interested in the topic of safety in social networks. The results of the survey then show a greater need to promote information literacy, computational thinking and safe behavior on social networks as well as safe use of ICT.","PeriodicalId":41192,"journal":{"name":"IPSI BgD Transactions on Internet Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82273369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
