You love building cool robot applications, tackling complex navigation challenges, and making hardware *do things*. What you probably *don't* love is the endless cycle of dependency conflicts, the "works on my machine" nightmares, being chained to specific Ubuntu versions, or wrestling with Docker just to get a consistent build. - [Devising a method for detecting and correcting multi-bit data transmission errors in IoT systems based on the Golay code](https://index.0x77.dev/paper/15587-1729-4061.2025.326222): The object of this study is information systems within the Internet of Things. The task addressed involves devising an innovative method for detecting and correcting multi-bit data transmission errors in the Internet of Things networks based on Golay codes. As the main result of the research, a method has been devised for detecting and correcting multi-bit data transmission errors based on Golay codes during byte-by-byte transmission of an information block. - [Methods and devices for network censorship circumvention](https://index.0x77.dev/patent/us11968254b1): Methods and devices for network censorship circumvention utilizing peer-to-peer networks to enable users in censored networks to access restricted content through volunteer peer devices in uncensored networks. - [Systems and methods for data quality and validity improvement in education institutional, degree, and course license management](https://index.0x77.dev/patent/wo2024107645a1): Systems and methods for providing an accreditation management system (AMS) to validate educational resources by performing content validation operations comprising applying a cryptographic hash function to educational resources to generate a content validation hash, receiving a data stream from a computing device of a student user engaged with the educational resources, applying the cryptographic hash function to each educational resource to generate a content consumption hash, and comparing the content validation hash to the content consumption hash.
