Юрія Гривняка - автора монографії про Івана Пулюя, яку було
опубліковано 1971 року у Лондоні завдяки фінансовій підтримці Союзу
українців у Великій Британії. Автором було використано ряд фото та
архівних матеріалів, отриманих від О. Пулюя. На жаль, творчість і
життєвий шлях Ю. Гривняка є маловідомими в Україні, а доля зібраних
ним джерел потребує фахового дослідженняThese theses are devoted to the study of the pages of Yuriy
Hryvniak’s biography. He was the author of a monograph dedicated to the study
of the life and activities of the famous Ukrainian scientist and public figure Ivan
Puluj. The author used a number of photos and archival materials received from
O. Puluj. Unfortunately, the creativity and life path of Y. Hryvniak is little
known in Ukraine, and the fate of the sources collected by him requires

On the limits of engine analysis for cheating detection in chess
No full textThe integrity of online games has important economic consequences for both the gaming industry and players of all levels, from professionals to amateurs. Where there is a high likelihood of cheating, there is a loss of trust and players will be reluctant to participate — particularly if this is likely to cost them money.
Chess is a game that has been established online for around 25 years and is played over the Internet commercially. In that environment, where players are not physically present “over the board” (OTB), chess is one of the most easily exploitable games by those who wish to cheat, because of the widespread availability of very strong chess-playing programs. Allegations of cheating even in OTB games have increased significantly in recent years, and even led to recent changes in the laws of the game that potentially impinge upon players’ privacy.
In this work, we examine some of the difficulties inherent in identifying the covert use of chess-playing programs purely from an analysis of the moves of a game. Our approach is to deeply examine a large collection of games where there is confidence that cheating has not taken place, and analyse those that could be easily misclassified.
We conclude that there is a serious risk of finding numerous “false positives” and that, in general, it is unsafe to use just the moves of a single game as prima facie evidence of cheating. We also demonstrate that it is impossible to compute definitive values of the figures currently employed to measure similarity to a chess-engine for a particular game, as values inevitably vary at different depths and, even under identical conditions, when multi-threading evaluation is used
Ivan Žuvela Šabo and His Etnographic Record from 1892
No full textU ovom tekstu otkriva se identitet autora jednog starijeg etnografskog zapisa nastalog na otoku Korčuli. Riječ je o rukopisu „Narodne pjesme junačke i žetelačke“ iz 1892., a koji se čuva u Arhivu Odsjeka za etnologiju Hrvatske akademije znanosti i umjetnosti u Zagrebu. Iako je u tom rukopisu autor potpisan kao „Ivan Žuvela, pravnik“, dosada ga se nije moglo točnije identificirati, iznesena je kriva pretpostavka, a čak se i spekuliralo da je riječ o pseudonimu. Istraživanjem dostupnih izvora i novinskih zapisa ipak se utvrdilo kako je zaista riječ o Velolučaninu Ivanu Žuveli iz grane Šabo, studentu prava koji je umro u svojoj 23-oj godini života, samo godinu dana po nastanku ovog rukopisa. Uz autora, u tekstu se detaljno progovara o rukopisu i njegovom iznimnom značaju za proučavanje nekadašnje svakodnevice, a posebno žetelačkih običaja na zapadnom dijelu otoka Korčule.This text reveals the identity of the hitherto unknown author one of the oldest known ethnographic record from the island of Korčula. The manuscript titled “Narodne pjesme junačke i žetelačke” (Folk Songs of Heroes and Harvesters) dates back to 1892 and is preserved in the Archive of the Ethnology Division at the Croatian Academy of Sciences and Arts in Zagreb. Although the author of the manuscript is signed as “Ivan Žuvela, legal scholar,” his precise identification has remained elusive, with incorrect assumptions and even speculation about a possible pseudonym. Through research of available sources and newspaper records, it has now been conclusively determined that the author is indeed Ivan Žuvela from Vela Luka, a member of the Šabo family, and a law student who passed away at the age of 23, just a year after creating this manuscript. In addition to introducing the author, this text provides a detailed exploration of the manuscript and its exceptional significance for studying the everyday life of the past, particularly the harvesting customs on the western part of the island of Korčula
