4 Commits • 2 Features
Oct 1, 2025In 2025-10, NavigaTUM delivered targeted data and UX improvements across the repository, focusing on data integrity, search accuracy, and asset management. Key features delivered include ZA4 campus location data refinement (updated building names/addresses and new identifiers for Taufkirchen/Ottobrunn) and an asset refresh for LG data (WebP encodings) to improve visual consistency and storage efficiency. Major bugs fixed include correcting the data update workflow to delete .csv files (not .json) and aligning snapshot tests for the search executor with actual data, boosting reliability. Overall impact includes more accurate mapping/search data, safer data updates, more efficient asset handling, and more robust tests, contributing to faster, more reliable data-driven decisions and an improved user experience. Technologies demonstrated include Git-based change management, data normalization and mapping, image asset management, and test maintenance.

Sep 1, 2025September 2025: Focused on strengthening typing safety in the NavigaTUM front-end. Delivered a critical bug fix for SelectionSwitch to allow the model prop to accept a generic string, aligning with newer TypeScript versions. This change improves compatibility, reduces type-related errors, and enhances maintainability as part of ongoing TS tooling upgrades. The work was carried out in the TUM-Dev/NavigaTUM repository with a traceable commit for accountability and future audits.

Apr 1, 2025April 2025 — NavigaTUM (TUM-Dev/NavigaTUM): Security remediation month focused on vulnerability mitigation by upgrading multiple Rust crates to address RUSTSEC-2025-0024. Core commit: 44f44f981fe6375764736efa920267fcf3a451fb ("bump dependencys to get around RUSTSEC-2025-0024 Resolves #1920"). Affected crates include crossbeam-channel, deranged, half, hostname, linux-raw-sys, miniz_oxide, redox_syscall, rustls, tracing-actix-web, and winnow. No new features shipped this month; the focus was on security posture, stability, and audit readiness. Impact: reduced attack surface, ensured Cargo.lock reflects patched versions, and maintained compatibility with dependent services. Technologies/skills demonstrated: Rust dependency management, security patching, Cargo.lock auditing, vulnerability remediation, and release hygiene.

Mar 1, 2025In March 2025, NavigaTUM delivered two core improvements that enhance data reliability and user experience. First, the room search was enhanced for accuracy and coverage, accommodating varied room naming conventions and locations, with tests updated to reflect new expectations and results (including handling labels like "(Gesperrt)"). Second, height data parsing for maps was made robust, validating numeric values, supporting an optional 'm' suffix, and removing units/spaces to prevent parsing errors and improve map rendering reliability. These changes included targeted test updates and were supported by multiple commits to ensure reliability and regression protection. Overall, this work improves search reliability, map rendering stability, and data quality, reducing downstream support needs and enabling faster, more accurate user interactions.
