The basic idea of is the Internet of Things is presence around us of a variety of things – such as RFID tags, sensors, actuators, mobile phones, etc. – which are able to interact with each other and cooperate with their neighbors to reach common goals. Semantic oriented IoT visions have also been proposed. The number of items involved in the future Internet is destined to become extremely high. Therefore, issues pertaining how to represent, store, interconnect, search, and organize information generated by the IoT will become very challenging. In this context, semantic technologies will play a key role. And creative approaches to visualizing data – humans are far better than computers at seeing patterns –frequently prove integral to the process of creating knowledge. From a privacy perspective, IoT is challenging because it operates in private settings, like homes, and presents an attack target that is harder to secure.
The article presents the basics of modern software testing theory. Testing automation and the integration of testing into code writing will be examined in detail, and concept of a testing environment for distributed systems will be introduced.
This article presents interface-related problems arising from a traditional keyboard. Some alternative suggestions for keyboard layout are discussed. Several ways of analyzing interfaces are introduced: the keystroke level model, the human processor model and cognitive walkthroughs.
The article outlines a wide range of issues related to human computer interface. The key concept here is the interface, however it may be defined. After presenting in short interface history, the interface research tools are discussed, especially eye movement tracing equipment. Principles of interface design (screen layout, error prevention, interaction design) are discussed later in more detail. A short presentation of specific issues – mobile phones and advertising banners follows. Interface concepts in development finish the article.

Personalizacja komputerowej reprezentacji wiedzy może dokonywać się w sposób wymuszony przez użytkownika lub w sposób automatyczny i może dotyczyć treści, architektury lub formy prezentacji wiedzy. Ważnym problemem dla takiej indywidualnej reprezentacji wiedzy jest pozyskiwanie aktualnych informacji dostępnych w zasobach sieci WWW. Autorzy analizują potrzeby w zakresie ewolucji zasobów wiedzy, identyfikują problemy badawcze, analizują dotychczasowe osiągnięcia w tej dziedzinie oraz proponują wykorzystanie różnych metod do realizacji zintegrowanego, rozproszonego, otwartego i personalizowanego modelu wiedzy.

Personalization of computer knowledge representation may be accomplished in both ways, individually by a user or automatically, and may be related to content, architecture or knowledge presentation form. The important issue of such an individual representation is updating of its current content by using information which is available on the internet. Authors analyze user's needs on the basis of knowledge resources evolution, identify research issues, analyze track record on this field of science and propose a utilization of different methods to create an integrated, open and personalized knowledge model.
