Abstract This paper examines events that occur synchronously around the globe at hackerspaces: during Global Synchronous Hackathons, participants use video streams to share experiences, work and interact in real time. This paper analyses synchronous hackathons through video repositories of these events. It aims at discerning what norms are enacted in presented hacking experiences and how those norms are communicated across the video streams. Hacking in these cases should be thought of as the creative activity of using technology to build something that solves a problem or challenge. Hackerspaces are social workshops and communities renting a physical space and usually interacting in digital spaces. In these environments, individuals are involved in hacking as combined social as well as solitary activities which, to some extent, embody certain norms. Individuals also create the “technological drama”; that is they create the discourse around the objects that inform their use and embed them in cultures. These cultures and their discourses possess norms which flow through them and exist around the objects. Members of hackerspaces commonly participate in the aforementioned “Synchronous Hackathons.” By comparing videos of these hackathons, I stress the relevance of norms which are not usually listed in reflections on hacker ethics such as those of Steven Levy or Pekka Himmanen: the awareness of the global other or the awareness of what might be termed “the cosmopolitical.” These norms seek to care for and attend to the people who exist at a distance. This transformation of local to global “hacker ethics” demonstrates the growth of the recognition, at least internally, that hackerspaces embody more than their local concerns: they are part of global movements with global interests and globalising norms. The video analysis is used to demonstrate the globalising norms of these communities as the norms surrounding cosmopolitics become more prevalent in their discourses.

Abstract The subject of the discussion in this paper is place in the sense of physical space and its role in creative activity. In the text, we emphasize that a physical place is implicitly defined as creative by the people who conduct or have conducted their creative activity there. We emphasize that it promotes a creative lifestyle and poses a challenge for education. We are looking for distinguishing features of creative places and spaces. In the paper, we also present a proposal to analyse creative places using Wilber’s (2007) integral theory and theory of affordance. Starting from the concepts of Florida (2010), Amabile (2019), Oldenburg (1989), and Palasma (2013), we list the conditions that a place should meet to promote creative activity. In the conclusions, we point to the role of creative affordances in education.

Maintenance professionals and other technical staff regularly need to learn to identify new parts in car engines and other equipment. The present work proposes a model of a task assistant based on a deep learning neural network. A YOLOv5 network is used for recognizing some of the constituent parts of an automobile. A dataset of car engine images was created and eight car parts were marked in the images. Then, the neural network was trained to detect each part. The results show that YOLOv5s is able to successfully detect the parts in real time video streams, with high accuracy, thus being useful as an aid to train professionals learning to deal with new equipment using augmented reality. The architecture of an object recognition system using augmented reality glasses is also designed.

A novel approach for preparing carbohydrate chips based on polydopamine (PDA) surface to study carbohydrate–lectin interactions by quartz crystal microbalance (QCM) biosensor instrument has been developed. The amino-carbohydrates were immobilized on PDA-coated quartz crystals via Schiff base reaction and/or Michael addition reaction. The resulting carbohydrate-chips were applied to QCM biosensor instrument with flow-through system for real-time detection of lectin–carbohydrate interactions. A series of plant lectins, including wheat germ agglutinin (WGA), concanavalin A (Con A), Ulex europaeus agglutinin I (UEA-I), soybean agglutinin (SBA), and peanut agglutinin (PNA), were evaluated for the binding to different kinds of carbohydrate chips. Clearly, the results show that the predicted lectin selectively binds to the carbohydrates, which demonstrates the applicability of the approach. Furthermore, the kinetics of the interactions between Con A and mannose, WGA and N-Acetylglucosamine were studied, respectively. This study provides an efficient approach to preparing carbohydrate chips based on PDA for the lectin–carbohydrate interactions study.
